RESUMEN
AIM: Evidence suggests an association between maternal hypothyroidism and risk of attention-deficit/hyperactivity disorder (ADHD) or autism spectrum disorder (ASD) in offspring. We examined the risk of ASD and ADHD in individuals with congenital hypothyroidism (CHT). METHODS: A nationwide population-based cohort study enrolled a total of 1260 children younger than 12 years with a confirmed diagnosis of CHT and no prior diagnosis of any neurodevelopmental disorders, selected from the National Health Insurance Research Database of Taiwan between 1998 to 2013. In addition, 12,600 controls matched for sex, age, and residence were selected. Cox proportional hazards analysis was used to investigate the association among CHT, ASD, and ADHD. RESULTS: Children with CHT were associated with a higher incidence of ASD (7.1 vs 1.3, P < 0.001) and ADHD (39.7 vs 18.7, P < 0.001) than the control group. Cox regression analyses demonstrated that children with CHT were associated with elevated risks of ASD (hazard ratio [HR], 4.72 [95% confidence interval (CI), 2.08-10.70]) and ADHD (HR, 2.03 [95% CI, 1.49-2.77]), after adjusting for demographic data and family history of major psychiatric disorders, compared with the control group. CONCLUSION: Children with CHT were associated with approximately a two-fold increased risk of ADHD and a four-fold increased risk of ASD than the control group. Our study highlights the need for future research to elucidate the potential pathophysiology among CHD, ASD, and ADHD.
RESUMEN
BACKGROUND: Inhibitory control function and proinflammatory cytokines play a role in the pathomechanisms underlying major affective disorders and suicidal behavior. However, the distinct or interactive effects of major affective disorders and suicidal symptom severity on inhibitory control function and proinflammatory cytokines remain unclear. METHODS: This study included 287 patients with bipolar disorder, 344 with major depressive disorder, and 169 healthy controls. We categorized the participants into three groups on the basis of Montgomery-Åsberg Depression Rating Scale (MADRS) item 10 (suicidal symptoms) score: 0, 2 or 3, and ≥4. The participants completed the go/no-go task and the measurements for C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α) levels. RESULTS: Errors in the go/no-go task were associated with suicidality (p = .040), regardless of the severity of suicidal symptoms and diagnosis. An elevated CRP level was especially associated with MADRS item 10 score ≥ 4 (p = 0.001). Increased TNF-α level could distinguish bipolar disorder from major depressive disorder (p < .001). DISCUSSION: Our study indicated the distinct effects of major affective disorder diagnosis and suicide symptom severity on inhibitory control function and CRP and TNF-α levels. Importantly, individuals with the poorest inhibitory control function and highest CRP levels had more severe suicidal symptoms.
RESUMEN
BACKGROUND: Anxiety disorders, major psychiatric disorders (e.g., schizophrenia and major affective disorders), and neurodevelopmental disorders (e.g., autism and attention-deficit/hyperactivity disorder [ADHD]) may cluster together within families. However, whether the first-degree relatives (FDRs) of individuals with generalized anxiety disorder (GAD) are at an elevated risk of neurodevelopmental or major psychiatric disorders remains unknown. METHODS: We identified 2,378,190 FDRs of patients with GAD and 9,512,760 birth year-matched and sex-matched controls from Taiwan's National Health Insurance Research Database. Neurodevelopmental disorders, including autism and ADHD, and major psychiatric disorders, including schizophrenia, bipolar disorder, major depressive disorder, obsessive-compulsive disorder, and GAD, were identified. RESULTS: The FDRs-parents, offspring, and siblings-of individuals with GAD were more likely to be diagnosed as having schizophrenia (relative risk: 1.22), bipolar disorder (1.36), major depressive disorder (1.29), autism (1.20), ADHD (1.52), obsessive-compulsive disorder (1.21), and GAD (1.61) than are the FDRs of individuals without GAD. CONCLUSION: Our findings support the notion of a familial coaggregation between GAD, major psychiatric disorders, and neurodevelopmental disorders. Future studies should elucidate the definitive genetic etiology of this familial coaggregation.
RESUMEN
Liver fibrosis is a commonly observed pathological phenomenon that occurs during the progression of various types of chronic liver diseases. The Hippo pathway is closely associated with the pathogenesis of liver fibrosis. Previous studies have shown that wedelolactone (WED) has a significant anti-hepatic fibrosis effect, whereas the target and mechanism underlying WED remain elusive. In this study, we found that WED significantly alleviated liver fibrosis and injury by inhibiting the expression of YAP and TAZ. In an in vitro model, WED suppressed the activation of hepatic stellate cells (HSCs) induced by TGF-ß1, as well as the mRNA and protein expression of α-SMA, YAP, and TAZ. The allosteric regulation of YAP by WED was confirmed using MD and CETSA. Moreover, specific knockdown or inhibition of YAP did not enhance the suppressive effect of WED on HSC activation or protein expression associated with fibrosis. These findings demonstrated that the administration of WED effectively alleviated liver fibrosis by suppressing the Hippo/YAP/TAZ pathways. In addition, YAP activity may be regulated by WED via allosteric regulation.
RESUMEN
OBJECTIVES: Previous studies have demonstrated poor oral hygiene in children with attention deficit hyperactivity disorder (ADHD). However, the association between ADHD and periodontitis is still unclear. METHODS: In all, 16,211 adolescents with ADHD and 162,110 age- and sex-matched controls participated in the study between 2001 and 2011. To identify the occurrence of periodontitis, the participants were followed up till the end of 2011. Confounding factors, including smoking, diabetes, and depressive disorder, were assessed and adjusted in the Cox regression models. RESULTS: Adolescents with ADHD (HR: 2.29) were more likely to develop periodontitis later in life than controls. We additionally observed the beneficial effect of atomoxetine (HR: 0.42) on the periodontitis risk among adolescents with ADHD. However, this finding should be interpreted cautiously given the small sample (n = 290) of children taking atomoxetine in the present study. CONCLUSIONS: ADHD is an independent risk factor for subsequent periodontitis development. Oral health should be closely monitored in adolescents with ADHD. Future investigation of the shared pathomechanisms between periodontitis and ADHD is warranted.
RESUMEN
Neurological disorders are the primary cause of human disability and mortality globally, however, current medications slightly alleviate some symptoms of degenerative diseases. Serine is an important amino acid for the brain function and involved in a variety of biosynthetic pathways and signal transduction processes. The imbalance of serine metabolism is associated with neurodegeneration, including neuroinflammation, oxidative stress and apoptosis. Altered activities of serine metabolizing enzymes and accumulation of serine metabolites affect the survival and function of nerve cells. Abnormal serine levels are observed in animal models with neurological diseases, but not all human studies, therefore, the maintenance of serine homeostasis is a potentially therapeutic strategy for neurological disorders. To date, physiological and pharmacological roles of serine in neurological diseases have not been systemically recapitulated, and the association between serine and neurological diseases is controversial. In this review, we summarize physicochemical properties of serine, biological processes of serine in the brain (source, biotransformation, and transport), and the application of serine in neurological diseases including Alzheimer's disease, schizophrenia, and depression. Here, we highlight physicochemistry, physiology, pharmacology, and therapeutic potentials of serine in the prevention and treatment of neurological dysfunction. Our work provides valuable hints for future investigation that will lead to a comprehensive understanding of serine and its metabolism in cellular physiology and pharmacology. Although broad by necessity, the review helps researchers to understand great potentials of serine in the prevention and treatment of neurological dysfunction.
RESUMEN
OBJECTIVES: To screen biomarkers for forensic identification of acute myocardial infarction (AMI) by non-targeted metabolomic studies on changes of urine metabolites in rats with AMI. METHODS: The rat models of the sham surgery group, AMI group and hyperlipidemia + acute myocardial infarction (HAMI) group were established. Ultra-high performance liquid chromatography-mass spectrometry (UPLC-MS) was used to analyze the changes of urine metabolic spectrometry in AMI rats. Principal component analysis, partial least squares-discriminant analysis, and orthogonal partial least squares-discriminant analysis were used to screen differential metabolites. The MetaboAnalyst database was used to analyze the metabolic pathway enrichment and access the predictive ability of differential metabolites. RESULTS: A total of 40 and 61 differential metabolites associated with AMI and HAMI were screened, respectively. Among them, 22 metabolites were common in both rat models. These small metabolites were mainly concentrated in the niacin and nicotinamide metabolic pathways. Within the 95% confidence interval, the area under the curve (AUC) values of receiver operator characteristic curve for N8-acetylspermidine, 3-methylhistamine, and thymine were greater than 0.95. CONCLUSIONS: N8-acetylspermidine, 3-methylhistamine, and thymine can be used as potential biomarkers for AMI diagnosis, and abnormal metabolism in niacin and nicotinamide may be the main causes of AMI. This study can provide reference for the mechanism and causes of AMI identification.

Studies have reported inconsistent results regarding associations between parental depression and offspring neurodevelopmental disorders, such as developmental delay and autism spectrum disorder (ASD). In all, 7,593 children who were born between 1996 and 2010 in Taiwan and had at least one parent with major depressive disorder and 75,930 birth-year- and sex-matched children of parents without major depressive disorder were followed from 1996 or time of birth to the end of 2011. Intergroup differences in neurodevelopmental conditions-including ASD, attention-deficit hyperactivity disorder (ADHD), tic disorder, developmental delay, and intellectual disability (ID)-were assessed. Compared with the children in the control group, the children of parents with major depression were more likely [hazard ratio (HR), 95% confidence interval (CI)] to develop ADHD (1.98, 1.80-2.18), ASD (1.52, 1.16-1.94), tic disorder (1.40, 1.08-1.81), developmental delay (1.32, 1.20-1.45), and ID (1.26, 1.02-1.55). Parental depression was associated with offspring neurodevelopmental disorders, specifically ASD, ADHD, developmental delay, ID, and tic disorder. Therefore, clinicians should closely monitor the neurodevelopmental conditions of children of parents with depression.
RESUMEN
OBJECTIVES: The association between specific types of malignancies and the subsequent risk of dementia remains unknown. DESIGN: A retrospective population-based cohort study based on data from Taiwan National Health Insurance Research Database. SETTING AND PARTICIPANTS: We recruited 32,250 patients who survived malignancies and 322,500 controls between 1998 and 2011 and followed them up until the end of 2013. MEASUREMENTS: Diagnoses of dementia (including Alzheimer's disease (AD), vascular dementia (VaD), and unspecified dementia) was made during the follow-up period. Cox regression analyses were performed after adjusting for potential confounders. A sensitivity analysis was conducted to exclude patients with prodromal dementia. RESULTS: Cancer survivors were more likely to develop AD (hazard ratio [HR]: 1.68, 95% confidence interval [CI]: 1.38-2.06), unspecified dementia (HR: 1.19, 95% CI: 1.07-1.32), and any dementia (HR: 1.26, 95% CI: 1.16-1.37) compared with controls after adjusting for potential confounders. Importantly, cancers of the digestive and genitourinary organs seem to be associated with AD, unspecified dementia, and any dementia, whereas only malignant neoplasms of the brain are more likely to develop into VaD. Sensitivity analyses after exclusion of the first three or five years of observation and after exclusion of case enrollment before 2009 or 2007 showed consistent findings. CONCLUSION: Cancer survivors are at higher risk of subsequent dementia. Different types of cancer survivors may contribute to variable risks of specific dementias. Further studies are necessary to investigate the underlying mechanisms in cancer survivors and patients with dementia.
RESUMEN
BACKGROUND: The mental health of child and adolescent intensive care unit (ICU) survivors is increasingly being researched. However, the literature on how various types of critical illness influence specific psychiatric disorders remains limited. METHODS: This study analyzed the data of 8704 child and adolescent ICU survivors and 87,040 age-, sex-, family income-, and residence-matched controls who were followed from enrollment to the end of 2013; the data covered the period from 1996 to 2013 and were extracted from a nationwide data set. The primary outcomes were the risks of five major psychiatric disorders (MPDs), namely schizophrenia, bipolar disorder (BD), major depressive disorder (MDD), obsessive compulsive disorder (OCD), and posttraumatic stress disorder (PTSD). RESULTS: Relative to the controls, the child and adolescent ICU survivors (mean age = 10.33 years) exhibited higher risks of developing five MPDs. The associated hazard ratios (HRs) and confidence intervals (CIs) are as follows: PTSD, HR = 4.67, 95 % CI = 2.42-9.01; schizophrenia, HR = 3.19, 95 % CI = 2.27-4.47; BD, HR = 2.02, 95 % CI = 1.33-3.05; OCD, HR = 1.96, 95 % CI = 1.21-3.16; and MDD, HR = 1.68, 95 % CI = 1.44-1.95. The risks of developing MPDs varied across multiple types of critical illness related to ICU admission. CONCLUSIONS: The risks of MPDs were significantly higher among the child and adolescent ICU survivors than among the controls. The development of appropriate MPD prevention strategies should be emphasized for this vulnerable population.

Cognitive deficits associated with oxidative stress and the dysfunction of the central nervous system are present in some neurodegenerative diseases, such as Alzheimer's disease and Parkinson's disease. Selenium (Se), an essential microelement, exhibits cognition-associated functions through selenoproteins mainly owing to its antioxidant property. Due to the disproportionate distribution of Se in the soil, the amount of Se varies greatly in various foods, resulting in a large proportion of people with Se deficiency worldwide. Numerous cell and animal experiments demonstrate Se deficiency-induced cognitive deficits and Se supplementation-improved cognitive performances. However, human studies yield inconsistent results and the mechanism of Se in cognition still remains elusive, which hinder the further exploration of Se in human cognition. To address the urgent issue, the review summarizes Se-contained foods (plant-based foods, animal-based foods, and Se supplements), brain selenoproteins, mechanisms of Se in cognition (improvement of synaptic plasticity, regulation of Zn2+ level, inhibition of ferroptosis, modulation of autophagy and de novo synthesis of L-serine), and effects of Se on cognitive deficits, as well as consequently sheds light on great potentials of Se in the prevention and treatment of cognitive deficits.

Background: Low-dose ketamine infusion has been demonstrated to exert antisuicidal effects on patients with treatment-resistant depression (TRD) and strong suicidal ideation. Although evidence suggests an association between hopelessness and suicidality, very few studies have investigated the antihopelessness effects of ketamine.Methods: This study included 84 patients with TRD and strong suicidal ideation. The diagnosis of depression was based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, diagnostic criteria for major depressive disorder. They were randomly assigned to receive a single infusion of either 0.5 mg/kg ketamine or 0.045 mg/kg midazolam. Hopelessness and suicidal symptoms were assessed at baseline, at 240 minutes postinfusion, and on Days 2, 3, 7, and 14 postinfusion. The assessments were performed using the self-report Beck Hopelessness Scale (BHS) and Positive and Negative Suicide Ideation Inventory (PANSI). The analysis focused on the positive and negative domains of the BHS and PANSI, respectively. The clinical trial was conducted between August 15, 2018, and November 30, 2021.Results: Statistical analyses performed using a generalized linear model revealed that the ketamine group had significantly higher PANSI-positive (P = .008) and lower PANSI-negative (P = .015) suicidal ideation scores on Day 2 postinfusion than did the midazolam group. At 240 minutes postinfusion, the ketamine group had significantly lower BHS-negative domain scores than did the midazolam group (P = .031). Notably, the observed ketamine-induced reduction in hopelessness at 240 minutes postinfusion was associated with its antisuicidal effect on Day 2 postinfusion.Discussion: A single infusion of low-dose ketamine resulted in a brief (â¼4 hours) yet significant reduction in hopelessness. Subjective antisuicidal effects of ketamine were noted on Day 2 postinfusion. Further studies are needed to elucidate the neuromechanisms underlying the antihopelessness and antisuicidal effects of ketamine.Trial Registration: UMIN Clinical Trials Registry identifiers: UMIN000033916 and UMIN000033760.

Age-related cognitive decline is a prominent concern in older adults and selenium (Se) deficiency has been found to be associated with cognitive deficits. For the first time, the present study explored the association between Se intake and cognitive performance in older people with/without cognitive impairment using the data from the National Health and Nutrition Examination Survey 2011-2014. Weighted linear regression models were conducted to evaluate the association between dietary Se/total Se intakes and cognitive assessments. A total of 2387 participants were included. The significant positive association between dietary Se/total Se intakes and total scores of cognitive functioning tests existed only in the older people with low cognitive performance (p < 0.001), not in those with normal cognitive performance. In conclusion, Se intake was beneficial for cognitive decline only in the low cognition older people but failed in normal cognition older people.
RESUMEN
Previous studies have shown an association between the thalamocortical dysconnectivity and treatment-resistant depression (TRD). Whether a single subanesthetic dose of ketamine may change thalamocortical connectivity among patients with TRD is unclear. Whether these changes in thalamocortical connectivity is associated with the antidepressant and antisuicidal effects of ketamine treatment is also unclear. Two resting-state functional MRIs were collected in two clinical trials of 48 patients with TRD (clinical trial 1; 32 receiving ketamine, 16 receiving a normal saline placebo) and 48 patients with TRD and strong suicidal ideation (clinical trial 2; 24 receiving ketamine, 24 receiving midazolam), respectively. All participants underwent rs-fMRI before and 3 days after infusion. Seed-based functional connectivity (FC) was analyzed in the left/right thalamus. FCs between the bilateral thalamus and right middle frontal cortex (BA46) and between the left thalamus and left anterior paracingulate gyrus (BA8) increased among patients in the ketamine group in clinical trials 1 and 2, respectively. FCs between the right thalamus and bilateral frontal pole (BA9) and between the right thalamus and left rostral paracingulate gyrus (BA10) decreased among patients in the ketamine group in clinical trials 1 and 2, respectively. However, the associations between those FC changes and clinical symptom changes did not survive statistical significance after multiple comparison corrections. Whether ketamine-related changes in thalamocortical connectivity may be associated with ketamine's antidepressant and antisuicidal effects would need further investigation. Clinical trials registration: UMIN Clinical Trials Registry (UMIN-CTR): Registration number: UMIN000016985 and UMIN000033916.
RESUMEN
Selenium (Se) is an essential trace element for humans and its low or high concentration in vivo is associated with the high risk of many diseases. It is important to identify influential factors of Se status. The present study aimed to explore the association between several factors (Se intake, gender, age, race, education, body mass index (BMI), income, smoking and alcohol status) and blood Se concentration using the National Health and Nutrition Examination Survey 2017-2020 data. Demographic characteristics, physical examination, health interviews and diets were compared among quartiles of blood Se concentration using the Rao-Scott χ2 test. Se levels were compared between the different groups of factors studied, measuring the strength of their association. A total of 6205 participants were finally included. The normal reference ranges of blood Se concentration were 142.3 (2.5th percentile) and 240.8 µg/L (97.5th percentile), respectively. The mean values of dietary Se intake, total Se intake and blood Se concentration of the participants were 111.5 µg/day, 122.7 µg/day and 188.7 µg/L, respectively, indicating they were in the normal range. Total Se intake was the most important contributor of blood Se concentration. Gender, race, education status, income, BMI, smoking and alcohol status were associated with blood Se concentration.

BACKGROUND: The risks of sexually transmitted infections (STIs) and teenage pregnancy in the offspring of parents with schizophrenia remain unknown. METHODS: From the Taiwan National Health Insurance Research Database, 5,850 individuals born between 1980 and 1999 having any parent with schizophrenia and 58,500 age-, sex-, income- and residence-matched controls without parents with severe mental disorders were enrolled in 1996 or on their birthdate and followed up to the end of 2011. Those who contracted any STI or became pregnant in adolescence during the follow-up period were identified. RESULTS: Cox regression analyses demonstrated that offspring of parents with schizophrenia (hazard ratio [HR]: 1.21, 95% confidence interval [CI]: 1.02-1.44), especially daughters (HR: 1.30, 95% CI: 1.06-1.58), were more likely to contract any STI later in life than the control comparisons. In addition, daughters of parents with schizophrenia had an elevated risk of being pregnant in their adolescence (HR: 1.47, 95% CI: 1.29-1.67) compared with those having no parents with severe mental disorders. DISCUSSION: The positive relationship between parental schizophrenia and offspring STIs and teenage pregnancy necessitates clinicians and public health officers to closely monitor the sexual health in the offspring of parents with schizophrenia so that optimal and prompt preventive measures can be taken in the at-risk group.
RESUMEN
OBJECTIVE: To study the effect of Shexiang Tongxin Dropping Pill (STDP) on angiogenesis in diabetic cardiomyopathy mice with coronary microcirculation dysfunction (CMD). METHODS: According to a random number table, 6 of 36 SPF male C57BL/6 mice were randomly selected as the control group, and the remaining 30 mice were injected with streptozotocin intraperitoneally to replicate the type 1 diabetes model. Mice successfully copied the diabetes model were randomly divided into the model group, STDP low-dose group [15 mg/(kg·d)], medium-dose group [30 mg/(kg·d)], high-dose group [60 mg/(kg·d)], and nicorandil group [15 mg/(kg·d)], 6 in each group. The drug was given by continuous gavage for 12 weeks. The cardiac function of mice in each group was detected at the end of the experiment, and coronary flow reserve (CFR) was detected by chest Doppler technique. Pathological changes of myocardium were observed by hematoxylin-eosin staining, collagen fiber deposition was detected by masson staining, the number of myocardial capillaries was detected by platelet endothelial cell adhesion molecule-1 staining, and the degree of myocardial hypertrophy was detected by wheat germ agglutinin staining. The expression of the vascular endothlial growth factor (VEGF)/endothelial nitric oxide synthase (eNOS) signaling pathway-related proteins in myocardial tissue was detected by Western blot. RESULTS: Compared with the model group, medium- and high-dose STDP significantly increased the left ventricular ejection fraction and left ventricular fraction shortening (P<0.01), obviously repaired the disordered cardiac muscle structure, reduced myocardial fibrosis, reduced myocardial cell area, increased capillary density, and increased CFR level (all P<0.01). Western blot showed that high-dose STDP could significantly increase the expression of VEGF and promote the phosphorylation of vascular endothelial growth factor receptor 2, phosphoinositide 3-kinase, protein kinase B, and eNOS (P<0.05 or P<0.01). CONCLUSION: STDP has a definite therapeutic effect on diabetic CMD, and its mechanism may be related to promoting angiogenesis through the VEGF/eNOS signaling pathway.
RESUMEN
In this study, we examined the risk of sexually transmitted infections (STIs) among adolescents and young adults (AYAs) with borderline personality disorder (BPD). A total of 4649 AYAs with BPD and 46,490 age-, sex-, and socioeconomic-matched controls without BPD were enrolled from the National Health Insurance Research Database of Taiwan from 2001 to 2009 and were followed up until the end of 2011. Participants who contracted any STI during the follow-up period were identified. Cox regression analysis was conducted to examine the risk of contracting any STI among both patients and controls. A total of 4649 AYAs with BPD and 46,490 age-, sex-, and socioeconomic-matched controls without BPD were enrolled from the National Health Insurance Research Database of Taiwan from 2001 to 2009 and were followed up until the end of 2011. Participants who contracted any STI (ICD-9-CM code 042, 091-097, 087.11, 078.8, 078.88, 131, and 054.1) during the follow-up period were identified. Cox regression and sub-analyses stratified by sex, age, psychiatric comorbidity subgroups, and psychotropic medication usage were conducted to assess STI risk. AYAs with BPD were at a higher risk of contracting any STI (hazard ratio [HR] = 50.79, 95% confidence interval [CI] = 33.45-77.11) in comparison with controls, including HIV, syphilis, genital warts, gonorrhea, chlamydia, trichomoniasis, and genital herpes. The association of BPD with an increased risk of any STI was prevalent in both sexes, adolescents, and young adult patients. BPD with or without psychiatric comorbid subgroup were all associated with an elevated risk of contracting any STI relative to the control group. AYAs with BPD are highly susceptible to contracting STIs. Future studies should examine the role of the core symptoms of BPD, sexual orientation, risky sex behaviors, depressive and anxiety symptoms, and substance use before sex in the risk of STIs among AYAs with BPD.
RESUMEN
Schizophrenia is highly comorbid with obsessive-compulsive disorder (OCD); both conditions share numerous pathophysiological etiologies. We, thus, examined the risk of mental disorders in the parents of probands with schizophrenia, OCD, or both conditions. Between 2001 and 2011, we enrolled a nationwide cohort of 69,813 patients with schizophrenia, OCD, or both. The control cohort included 698,130 individuals matched for demographics. Poisson regression models were employed to examine the risk of six mental disorders in their parents, including schizophrenia, bipolar disorder, depressive disorder, OCD, alcohol use disorder, and substance use disorder. We stratified patients into schizophrenia-only, OCD-only, and dual-diagnosis groups, and the dual-diagnosis group was further divided into schizophrenia-first, OCD-first, and simultaneously diagnosed groups. Compared with controls, the schizophrenia, OCD, and dual-diagnosis groups had higher risks for the six mental disorders in their parents (range of odds ratio [OR] 1.50-7.83). The sub-analysis of the dual-diagnosis group showed that the schizophrenia-first, OCD-first, and simultaneously diagnosed groups had higher odds for schizophrenia, bipolar disorder, depressive disorder, and OCD (range of OR 1.64-6.45) in their parents than the control group; the simultaneously diagnosed and OCD-first diagnosed groups had a higher odds of parental substance use disorder, while the schizophrenia-first diagnosed group had a higher odds of parental alcohol use disorder. The interrelationship between OCD and schizophrenia is linked to bipolar disorder, depressive disorder, alcohol use disorder, and substance use disorder. The results have implications for mental health policy and future research.
RESUMEN
This study aimed to explore the mechanism of Shexiang Tongxin Dropping Pills(STDP) in treating diabetic cardiomyopathy(DCM) based on network pharmacology, molecular docking, and animal experiments. BATMAN, TCMSP, and GeneCards were searched for the active ingredients and targets of STDP against DCM. STRING and Cytoscape were used to build the protein-protein interaction(PPI) network and "drug-active ingredient-target" network. Gene Ontology(GO) functional annotation and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analysis of the targets were carried out based on DAVID. The molecular docking of key receptor proteins with corresponding active ingredients was performed using AutoDock Vina. The rat model of DCM was established by a high-fat diet combined with intraperitoneal injection of streptozotocin. Rats were assigned into control, model, low-(20 mg·kg~(-1)) and high-dose(40 mg·kg~(-1)) STDP, and metformin(200 mg·kg~(-1)) groups. After 8 weeks of continuous administration, the cardiac function, myocardial pathological changes, and myocardial collagen fiber deposition of rats in each group were detected by echocardiography, hematoxylin-eosin(HE) staining, and Sirius red staining, respectively. The myocardial hypertrophy was detected by WGA staining. The expression levels of p38 mitogen-activated protein kinase(p38), phosphorylation-p38(p-p38), c-Jun N-terminal kinase(JNK), phosphorylation-JNK(p-JNK), caspase-3, and C-caspase-3 in the myocardial tissue of rats in each group were measured by Western blot. The network pharmacology predicted 199 active ingredients and 1 655 targets of STDP and 463 targets of DCM. One hundred and thirty-four potential targets of STDP for treating DCM were obtained, and the AGE-RAGE signaling pathway in diabetic complications was screened out. Molecular docking results showed that miltirone, dehydromiltirone, and tryptanthrin had strong binding affinity with RAGE. The results of animal experiments confirmed that STDP effectively protected the cardiac function of DCM rats. Compared with the DCM model group, the STDP groups showed significantly down-regulated protein levels of p-p38, p-JNK, and C-caspase-3. To sum up, STDP may protect the cardiac function of DCM rats by regulating the AGE-RAGE signaling pathway.
