RESUMEN

BACKGROUND: In recent years, the incidence of depression during pregnancy has gradually increased, and the disorder of lipid metabolism in patients with depression is an important research direction. Therefore, this study aimed to explore the correlation between depression during pregnancy and metabolic syndrome (MS). METHODS: A total of 113 pregnant women diagnosed as depression during pregnancy from November 2019 to January 2022 were selected as the observation group. After excluding 3 cases, 110 cases were finally included. And 102 pregnant women who were not diagnosed as depression during pregnancy in the same period were selected as the control group. After excluding 2 cases, 100 cases were finally included for comparative study. The levels of various parameters, including serum triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C), fasting plasma glucose (FPG), C-reactive protein (CRP), systolic blood pressure (SBP), and diastolic blood pressure (DBP) were compared between the two groups. Furthermore, the Edinburgh Postnatal Depression Scale (EPDS) was used to evaluate the depression scores of postpartum women. Additionally, the correlation between EPDS scores and clinical indexes was assessed in patients with depression during pregnancy. RESULTS: We observed that the body weight, EPDS score, the proportion of hyperglycemia, hypertension, and dyslipidemia were significantly higher in the observation group compared to the control group (p < 0.001). Furthermore, the observation group exhibited significantly higher levels of TG, TC, HDL-C, LDL-C, FPG, CRP, SBP, and DBP than the control group (p < 0.001). Pearson linear correlation analysis revealed that TG, TC, HDL-C, LDL-C, FPG, CRP, SBP, and DBP levels were positively correlated with EPDS scores (p < 0.001). CONCLUSION: This study indicates a specific correlation between MS and depression during pregnancy, and MS-related indicators are positively correlated with EPDS scores among these individuals.

RESUMEN

INTRODUCTION: Cystic adenomyosis is a rare variant of adenomyosis, with only 90 reported cases found in the literature so far. Diverticulum-like adenomyosis is even more uncommon, with only one documented case to date. CASE PRESENTATION: We report the case of a 42-year-old asymptomatic woman who had an incidental finding of a parauterine cyst on an abdominal computed tomography scan. B-ultrasonography also revealed an endometriotic cyst. Further MRI revealed a cystic lesion measuring 7.6 × 6.1 × 7.7 cm that communicated with the uterine cavity through a tiny channel. The fluid in the cyst showed high signal intensity on T1-weighted image (T1WI), and the cyst wall showed a marked low signal intensity on T2-weighted image (T2WI). No other masses were found on either side. After obtaining informed consent, we performed a laparoscopic exploration on the patient, where it became apparent that the 7.6 × 6.1 × 7.7 cm cystic mass was located on the left uterine isthmus-the excised lesion contained chocolate-like fluid within a thickened wall. Pathological examination revealed typical endometrial glands and interstitial tissues in the cystic wall. DISCUSSION: Cystic adenomyosis is a rare benign lesion in women of reproductive age that is known to cause hypermenorrhea, dysmenorrhea, and abnormal uterine bleeding. Our case represents the second documented case of diverticulum-like adenomyosis. However, the patient in our case did not exhibit abnormal uterine bleeding or dysmenorrhea. One possible explanation for this finding is that the sinus tract was too small to cause blood influx into the uterine cavity. CONCLUSION: Our case report provides valuable insights for clinicians to better understand this uncommon disease and reduce the incidence of misdiagnosis.

RESUMEN

Recent studies have shown that prostate cancer-associated long non-coding RNA, PRNCR1, plays crucial roles in the development of multiple human cancers. However, its role in ovarian cancer is barely known. This study was carried out to investigate the role of PRNCR1 and the underlying mechanisms in OC. The expression of PRNCR1 and miR-653-5p in OC cell lines and tissues were detected by qRT-PCR. The expression of ELF2 protein was evaluated by Western blot analysis. Cell proliferation was measured by colony formation and MTT assay. Cell invasion and migration were evaluated by Transwell and wound healing assay. Luciferase reporter assay and RNA-binding protein immunoprecipitation assay were performed to determine the interaction between miR-653-5p and PRNCR1, as well as between miR-653-5p and ELF2. In vivo tumor xenograft model was established to evaluate the role of PRNCR1 in tumor growth. Our results demonstrated that PRNCR1 was significantly upregulated in both OC cell lines and tissues, and high expression of PRNCR1 was correlated with poor survival of OC patients. Overexpression of PRNCR1 accelerated OC cell invasion, migration and proliferation. Besides, the expression of PRNCR1 was negatively correlated with the expression of miR-653-5p, while positively correlated with the expression of E74-like factor 2 in OC tissues. Importantly, ELF2 could target miR-653-5p, and PRNCR1 increased the expression levels of ELF2 by sponging miR-653-5p in OC cells. Furthermore, the miR-145-5p/ELF2 axis was involved in the regulation of PRNCR1 in OC progression in vivo. PRNCR1 promotes OC tumor progress via the miR-653-5p/ELF2 axis and might be a potential therapeutic target for OC.

RESUMEN

BACKGROUND: Citrin deficiency (CD) is an autosomal recessive disease resulting from biallelic mutations of the SLC25A13 gene. This study aimed to investigate the molecular epidemiological features of CD in the Guangdong and Shaanxi provinces of China. METHODS: A total of 3,409 peripheral blood samples from Guangdong and 2,746 such samples from Shaanxi province were collected. Four prevalent SLC25A13 mutations NG_012247.2 (NM_014251.3): c.852_855del, c.1638_1660dup, c.615+5G>A, and c.1751-5_1751-4ins(2684) were screened by using the conventional polymerase chain reaction (PCR)/PCR-restriction fragment length polymorphism and newly-developed multiplex PCR methods, respectively. The mutated SLC25A13 allele frequencies, carrier frequencies, and CD morbidity rates were calculated and then compared with the Chi-square and Fisher's exact tests. RESULTS: The mutations were detected in 68 out of 6,818 SLC25A13 alleles in Guangdong and 29 out of 5,492 alleles in the Shaanxi population. The carrier frequencies were subsequently calculated to be 1/51 and 1/95, while the CD morbidity rates were 1/10,053 and 1/35,865, in the 2 populations, respectively. When compared with the Shaanxi population, Guangdong exhibited a higher frequency of mutated SLC25A13 allele (68/6,818 vs. 29/5,492, χ2=8.570, P=0.003) in general, with higher c.852_855del (54/6,818 vs. 13/5,492, χ2=17.328, P=0.000) but lower c.1751-5_1751 -4ins(2684) (2/6,818 vs. 9/5,492, P=0.015) allele frequencies. The distribution of c.615+5G>A and c.1638_1660dup between the 2 provinces, as well as all 4 prevalent mutations among different geographic regions within the 2 provinces, did not differed significantly. CONCLUSIONS: Our findings depicted the CD molecular epidemiological features in Guangdong and Shaanxi populations, providing preliminary but significant laboratory evidences for the subsequent CD diagnosis and management in the 2 provinces of mainland China.

RESUMEN

OBJECTIVE: This research was designed to probe into the clinical significance of anti-mullerian hormone (AMH) levels in early missed abortion. METHODS: Forty-six women with early missed abortions treated in our hospital from October 2018 to June 2019 were collected as the research subjects and included in the observation group (OG), while 51 normal pregnant women were included in the control group (CG) during the same period. The levels of AMH, human follicle stimulating hormone (FSH) and human luteinizing hormone (LH) in the serum of women of both groups were tested by enzyme-linked immunosorbent assay (ELISA). The diagnostic value of AMH in early missed abortion was analyzed by receiver operating characteristic (ROC). The correlation between AMH and FSH, LH was assessed via Pearson correlation. According to the median expression of AMH before treatment, patients were divided into high and low expression groups (HEG, LEG, respectively), and time of vaginal bleeding and menstrual resurgence, and the incidence of coagulation dysfunction were compared after operation. RESULTS: The AMH and FSH levels in serum of patients in the OG were obviously lower than those in the CG, and the LH level was markedly higher. The area under the curve of serum AMH was 0.867. AMH was positively correlated with FSH and negatively correlated with LH. The time of vaginal bleeding and menstruation resurgence of the HEG patients were remarkably lower than those of the LEG (All P < 0.05). CONCLUSION: Serum AMH level is expected to be a good prognostic indicator in diagnosing early missed abortion.

RESUMEN

BACKGROUND: On January 20, 2020, a new coronavirus epidemic with human-to-human transmission was officially declared by the Chinese government, which caused significant public panic in China. In light of the coronavirus disease 2019 outbreak, pregnant women may be particularly vulnerable and in special need for preventive mental health strategies. Thus far, no reports exist to investigate the mental health response of pregnant women to the coronavirus disease 2019 outbreak. OBJECTIVE: This study aimed to examine the impact of coronavirus disease 2019 outbreak on the prevalence of depressive and anxiety symptoms and the corresponding risk factors among pregnant women across China. STUDY DESIGN: A multicenter, cross-sectional study was initiated in early December 2019 to identify mental health concerns in pregnancy using the Edinburgh Postnatal Depression Scale. This study provided a unique opportunity to compare the mental status of pregnant women before and after the declaration of the coronavirus disease 2019 epidemic. A total of 4124 pregnant women during their third trimester from 25 hospitals in 10 provinces across China were examined in this cross-sectional study from January 1, 2020, to February 9, 2020. Of these women, 1285 were assessed after January 20, 2020, when the coronavirus epidemic was publicly declared and 2839 were assessed before this pivotal time point. The internationally recommended Edinburgh Postnatal Depression Scale was used to assess maternal depression and anxiety symptoms. Prevalence rates and risk factors were compared between the pre- and poststudy groups. RESULTS: Pregnant women assessed after the declaration of coronavirus disease 2019 epidemic had significantly higher rates of depressive symptoms (26.0% vs 29.6%, P=.02) than women assessed before the epidemic declaration. These women were also more likely to have thoughts of self-harm (P=.005). The depressive rates were positively associated with the number of newly confirmed cases of coronavirus disease 2019 (P=.003), suspected infections (P=.004), and deaths per day (P=.001). Pregnant women who were underweight before pregnancy, primiparous, younger than 35 years, employed full time, in middle income category, and had appropriate living space were at increased risk for developing depressive and anxiety symptoms during the outbreak. CONCLUSION: Major life-threatening public health events such as the coronavirus disease 2019 outbreak may increase the risk for mental illness among pregnant women, including thoughts of self-harm. Strategies targeting maternal stress and isolation such as effective risk communication and the provision of psychological first aid may be particularly useful to prevent negative outcomes for women and their fetuses.

RESUMEN

Medical care has become an indispensable part of people's lives, with a dramatic increase in the volume of medical data (e.g., diagnosis certificates and medical records). Medical data, however, is easily stolen, tampered with, or even completely deleted. If the above occurs, medical data cannot be recorded or retrieved in a reliable manner, resulting in delay treatment progress, even endanger the patient's life. In this paper, we propose a novel blockchain-based data preservation system (DPS) for medical data. To provide a reliable storage solution to ensure the primitiveness and verifiability of stored data while preserving privacy for users, we leverage the blockchain framework. With the proposed DPS, users can preserve important data in perpetuity, and the originality of the data can be verified if tampering is suspected. In addition, we use prudent data storage strategies and a variety of cryptographic algorithms to guarantee user privacy; e.g., an adversary is unable to read the plain text even if the data are stolen. We implement a prototype of the DPS based on the real world blockchain-based platform Ethereum. Performance evaluation results demonstrate the effectiveness and efficiency of the proposed system.

RESUMEN

BACKGROUND INFORMATION: Angiotensin-(1-7) [ANG-(1-7)] mediates vasodilation, antiproliferation, anti-apoptosis and antifibrosis, therefore, it opposes the effects of angiotensin II (ANG II). However, the detailed signal transduction mechanism following the Mas receptor activated by ANG-(1-7) is still poorly understood. Src homology2-containing inositol phosphatase 1 (SHP-1), a redoxsensitive protein tyrosine phosphatase, negatively influences downstream signalling molecules, such as mitogen-activated protein kinases (MAPKs), through dephosphorylation, thereby inhibiting proliferative and profibrotic signalling induced by ANG II. Therefore, we hypothesised that SHP-1 may mediate the antiproliferative signalling of ANG-(1-7) through the regulation of the dynamic balance of MAPKs and SHP-1 in isolated cardiac fibroblasts. Primary culture of neonatal Sprague-Dawley rats cardiac fibroblasts was treated separately with different interventions to investigate this issue. RESULTS: Our data revealed that ANG II increased the phosphorylation of extracellular signal-related kinase (p-ERK1/2) and the ratio of (p-ERK1/2)/(ERK1/2), but ANG-(1-7) decreased them. The effects of ANG-(1-7) on the phosphorylation p-ERK1/2 were blocked by the Mas receptor antagonist A-779. Unlike ANG II, which decreased the activity of SHP-1, ANG-(1-7) increased its activity. Overexpression of SHP-1 attenuated the ANG II-stimulated phosphorylation of c-Src, its downstream molecules ERK1/2, α-smooth muscle actin and transforming growth factor-ß1 (TGF-ß1). These effects were also inhibited by the specific inhibitor of SHP-1, sodium stibogluconate. ANG-(1-7) had no significant effects on the gene expression of TGF-ß1, collagen I or collagen III, but was found to antagonise the stimulatory effects of ANG II on them. CONCLUSIONS: ANG-(1-7), through Mas receptor, activates SHP-1 in cardiac fibroblasts, which can negatively modulate ANG II-induced phosphorylation of c-Src and MAPKs, and inhibits profibrotic factors TGF-ß1 and collagen production. ANG-(1-7) can thereby serve as a protective role by counteracting the effects of ANG II.

RESUMEN

OBJECTIVE: To investigate root canal curvature in maxillary anterior teeth. METHODS: About 400 human maxillary anterior teeth were examined by indirect digital radiography both from labiolingual and mesiodistal directions. The root canal curvature was analyzed. RESULTS: The major sort of maxillary anterior teeth was type I. The proportion of maxillary center incisors, maxillary lateral incisors, maxillary canines curved in mesiodistal were 11.17%, 16.19% and 21.43%, in labio-lingual were 39.59%, 40.00% and 29.59%, both in labiolingual and mesiodistal directions were 4.60%, 35.24% and 24.49%. About 50% of maxillary anterior teeth were moderate curve, the degree of root canal curvature of maxillary canines was larger than that of maxillary incisors, and radius of curvature and length of the curved part of root canal of maxillary canines were smaller than that of maxillary incisors. CONCLUSION: Root canal curvature in maxillary anterior is complex, especially in maxillary canine. In order to improve quality of root canal therapy, we need to understand types of root canal, degree of root canal curvature and radius of curvature completely.
