RESUMO
BACKGROUND: The diagnosis of peripheral isolated nodular lesions that are suspected as pulmonary tuberculosis (PTB) is challenging, which are not easily accessible via conventional bronchoscopy. This study evaluated the combined use of Xpert MTB/RIF assay and endobronchial ultrasonography with a guide sheath (EBUS-GS) for detecting MTB infection in peripheral lung bands, for early detection of PTB. METHODS: The clinical data of 232 patients with suspected peripheral nodular PTB who underwent EBUS-GS between June 2020 and October 2023 were retrospectively reviewed. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and area under the curve (AUC) of acid-fast bacilli smear, culture, Xpert MTB/RIF assay, and pathological examination were calculated. To assess diagnostic accuracy, the results of the four methods were directly compared with the final clinical diagnosis. RESULTS: In total, 146 and 86 patients were clinically diagnosed with peripheral nodular PTB and non-PTB, respectively. The sensitivity, specificity, PPV, NPV, and AUC values of combined Xpert MTB/RIF assay and EBUS-GS were 47.26%, 100.0%, 100.0%, 52.76%, and 0.74; those of acid-fast bacilli smear were 8.22%, 97.67%, 85.71%, 38.53%, and 0.53; those of culture were 31.51%, 100.0%, 100.0%, 46.24%, and 0.66; and those of pathological examination were 23.97%, 97.67%, 94.59%, 43.08%, and 0.61, respectively. CONCLUSION: The diagnostic accuracy of the combined Xpert MTB/RIF assay and EBUS-GS was significantly better than that of other conventional tests. Hence, this novel technique can be routinely applied for diagnosing and managing peripheral nodular PTB.

This study conducted a pharmacoeconomic evaluation of Shaoma Zhijing Granules in the treatment of tic disorder(TD) in children. Firstly, from the perspective of the healthcare system, cost-effectiveness analysis was used to evaluate the economic efficiency of Shaoma Zhijing Granules compared with Changma Xifeng Tablets and Jiuwei Xifeng Granules in the treatment of TD in children. Then, through network Meta-analysis, the overall effectiveness of different regimens was calculated, combined with the total cost of the regimens, to calculate the incremental cost-effectiveness ratio(ICER). Finally, sensitivity analysis was performed to verify the stability of the study results and the credibility of the conclusions. This study included 17 articles, including 9 articles on Chinese patent medicines(3 on Shaoma Zhijing Granules, 2 on Jiuwei Xifeng Granules, and 4 on Changma Xifeng Tablets), for the treatment of TD in children, and 8 articles on Chinese patent medicines combined with conventional western medicines(3 on Shaoma Zhijing Granules, 2 on Jiuwei Xifeng Granules, and 3 on Changma Xifeng Tablets). In the Chinese patent medicine group, the total cost of Shaoma Zhijing Granules for treating TD was CNY 4 410.00, with clinical total effective rate of 77.53%; the total cost of Jiuwei Xifeng Granules for treating TD was CNY 5 192.70, with clinical total effective rate of 82.13%. The ICER of Jiuwei Xifeng Granules vs Shaoma Zhijing Granules was 169.95, higher than the willingness-to-pay(WTP, cost of increasing efficiency by 1% is CNY 85.70). Therefore, Jiuwei Xifeng Granules did not have a cost-effectiveness advantage over Shaoma Zhijing Granules. The total cost of Changma Xifeng Tablets for treating TD was CNY 1 282.50, with clinical total effective rate of 80.60%. The total cost of Changma Xifeng Tablets was lower and clinical total effective rate was higher than that of Shaoma Zhijing Granules. Overall, Shaoma Zhijing Granules did not have a cost-effectiveness advantage. In the Chinese patent medicine combined with conventional western medicine group, the total cost of Shaoma Zhijing Granules for treating TD + conventional western medicines was CNY 6 768.52/6 778.48, with clinical total effective rate of 96.18%. The total cost of Jiuwei Xifeng Granules + conventional western medicines for treating TD was CNY 6 522.56, with clinical total effective rate of 88.30%. The ICER of Shaoma Zhijing Granules + conventional western medicines vs Jiuwei Xifeng Granules + conventional western medicines was 31.20, lower than WTP. Therefore, Shaoma Zhijing Granules + conventional western medicines had a cost-effectiveness advantage over Jiuwei Xifeng Granules + conventional western medicines. The total cost of Changma Xifeng Tablets + conventional western medicines for treating TD was CNY 1 706.12, with clinical total effective rate of 95.39%. The ICER of Shaoma Zhijing Granules + conventional western medicines vs Changma Xifeng Tablets + conventional western medicines was 6 334.06, higher than WTP. Therefore, although Shaoma Zhijing Granules + conventional western medicines had higher clinical total effective rate compared with Changma Xifeng Tablets + conventional western medicines, it did not have a cost-effectiveness advantage. Overall, for different medication regimens(Chinese patent medicines monotherapy or in combination with conventional western medicines), Shaoma Zhijing Granules and Jiuwei Xifeng Granules both had a cost-effectiveness advantage, but compared with Changma Xifeng Tablets, neither had a cost-effectiveness advantage. For Chinese patent medicines in combination with conventional western medicines, clinical total effective rate of Shaoma Zhijing Granules in combination with conventional western medicines for the treatment of TD in children was the highest.

The National Nutrition Plan(2017-2030) and the Healthy China Action Plan(2019-2030) propose to vigorously develop traditional dietary care services, fully leverage the role of traditional dietary care in modern nutrition, and guide citizens to develop dietary habits that are in line with the dietary characteristics of different regions in China. Traditional dietary care has a long history in China and is one of the brilliant treasures of Chinese cuisine and traditional Chinese medicine(TCM) culture. It has played an important role in disease prevention, treatment, and health preservation and longevity. To promote the traditional culture of TCM, and guide and standardize the application and promotion of dietary care, it is necessary to develop a dietary care guideline with TCM characteristics. Based on the theories and practices of TCM, the China Academy of Chinese Medical Sciences(CACMS) has developed this guideline, which is tailored to local conditions and combined with modern nutrition, and targets people with different physical constitutions. According to the principles of dialectical diet, tailored to people, times, and local conditions, reinforcing healthy qi, correction, the combination of meat and vegetables, and the combination of four qi and five flavors, suitable ingredients are recommended(including TCM materials that are both food and medicinal materials). By promoting the popularization and development of traditional dietary care, this guideline contributes to integrating the strength of TCM into a unique nutritional and health model with Chinese characteristics.

BACKGROUND: Acute appendicitis (AA) is the most common cause of acute abdomen in children. Anesthesia significantly influences the surgical treatment of AA in children, making the scientific and effective selection of anesthetics crucial. AIM: To assess the clinical effect of atropine (ATR) in combination with remifentanil (REMI) in children undergoing surgery for AA. METHODS: In total, 108 cases of pediatric AA treated between May 2020 and May 2023 were selected, 58 of which received ATR + REMI [research group (RG)] and 50 who received REMI [control group (CG)]. Comparative analyses were conducted on the time to loss of eyelash reflex, pain resolution time, recovery time from anesthesia, incidence of adverse events (AEs; respiratory depression, hypoxemia, bradycardia, nausea and vomiting, and hypotension), intraoperative responses (head shaking, limb activity, orientation recovery, safe departure time from the operating room), hemodynamic parameters [oxygen saturation (SPO2), mean arterial pressure, heart rate, and respiratory rate], postoperative sedation score (Ramsay score), and pain level [the Face, Legs, Activity, Cry, Consolability (FLACC) Behavioral Scale]. RESULTS: Compared with the CG, the RG showed significantly shorter time to loss of eyelash reflex, pain resolution, recovery from anesthesia, and safe departure from the operating room. Furthermore, the incidence rates of overall AEs (head shaking, limb activity, etc.) were lower, and influences on intraoperative hemodynamic parameters and stress response indexes were fewer. The Ramsay score at 30 min after extubation and the FLACC score at 60 min after extubation were significantly lower in the RG than in the CG. CONCLUSION: ATR + REMI is superior to REMI alone in children undergoing AA surgery, with a lower incidence of AEs, fewer influences on hemodynamics and stress responses, and better post-anesthesia recovery.
RESUMO
BACKGROUND: Plerocercoid larvae of the tapeworm Spirometra mansoni can infect both humans and animals, leading to severe parasitic zoonosis worldwide. Despite ongoing research efforts, our understanding of the developmental process of S. mansoni remains inadequate. To better characterize posttranslational regulation associated with parasite growth, development, and reproduction, a comparative phosphoproteomic study was conducted on the plerocercoid and adult stages of S. mansoni. METHODS: In this study, site-specific phosphoproteomic analysis was conducted via 4D label-free quantitative analysis technology to obtain primary information about the overall phosphorylation status of plerocercoids and adults. RESULTS: A total of 778 differentially abundant proteins (DAPs) were detected between adults and plerocercoids, of which 704 DAPs were upregulated and only 74 were downregulated. DAPs involved in metabolic activity were upregulated in plerocercoid larvae compared with adults, whereas DAPs associated with binding were upregulated in adults. Gene Ontology (GO) and Kyoto Encyclopedia of Genes (KEGG) analyses indicated that most DAPs involved in signal transduction and environmental information processing pathways were highly active in adults. DAPs upregulated in the plerocercoid group were enriched mainly in metabolic activities. The kinases PKACA, GSK3B, and smMLCK closely interact, suggesting potential active roles in the growth and development of S. mansoni. CONCLUSIONS: The dataset presented in this study offers a valuable resource for forthcoming research on signaling pathways as well as new insights into functional studies on the molecular mechanisms of S. mansoni.

Ischemic stroke is one of the most disabling and fatal diseases around the world. The damaged brain tissues will undergo excessive autophagy, vascular endothelial cells injury, blood-brain barrier (BBB) impairment and neuroinflammation after ischemic stroke. However, there is no unified viewpoint on the underlying mechanism of brain damage. Transforming growth factor-ß1 (TGF-ß1), as a multi-functional cytokine, plays a crucial role in the intricate pathological processes and helps maintain the physiological homeostasis of brain tissues through various signaling pathways after ischemic stroke. In this review, we summarize the protective role of TGF-ß1 in autophagic flux, BBB, vascular remodeling, neuroinflammation and other aspects after ischemic stroke. Based on the review, we believe that TGF-ß1 could serve as a key target for treating ischemic stroke.

OBJECTIVE: This study aimed to evaluate the efficiency of nanopore sequencing for the early diagnosis of tuberculous meningitis (TBM) using cerebrospinal fluid and compared it with acid-fast bacilli (AFB) smear, mycobacterial growth indicator tube culture and Xpert Mycobacterium tuberculosis (MTB)/rifampicin (RIF). DESIGN: Single-centre retrospective study. SETTING: The Tuberculosis Diagnosis and Treatment Center of Zhejiang Chinese and Western Medicine Integrated Hospital. PARTICIPANTS: We enrolled 64 adult patients with presumptive TBM admitted to our hospital from August 2021 to August 2023. METHODS: We calculated the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of AFB smear, culture, Xpert MTB/RIF and nanopore sequencing to evaluate their diagnostic efficacy compared with a composite reference standard for TBM. RESULTS: Among these 64 patients, all tested negative for TBM by AFB smear. The sensitivity, specificity, PPV and NPV were 11.11%, 100%, 100% and 32.2% for culture, 13.33%, 100%, 100% and 2.76% for Xpert MTB/RIF, and 77.78%, 100%, 100% and 65.52% for nanopore sequencing, respectively. CONCLUSION: The diagnostic accuracy of the nanopore sequencing test was significantly higher than that of conventional testing methods used to detect TBM.

Acute postsurgical pain (APSP) has received growing attention as a surgical outcome. When poorly controlled, APSP can affect short- and long-term outcomes in patients. Despite the steady increase in awareness about postoperative pain and standardization of pain prevention and treatment strategies, moderate-to-severe APSP is frequently reported in clinical practice. This is possibly because pain varies widely among individuals and is influenced by distinct factors, such as demographic, perioperative, psychological, and genetic factors. This review investigates the risk factors for APSP, including gender, age, obesity, smoking history, preoperative pain history, pain sensitivity, preoperative anxiety, depression, pain catastrophizing, expected postoperative pain, surgical fear, and genetic polymorphisms. By identifying patients having an increased risk of moderate-to-severe APSP at an early stage, clinicians can more effectively manage individualized analgesic treatment protocols with a combination of pharmacological and non-pharmacological interventions. This would alleviate the transition from APSP to chronic pain and reduce the severity of APSP-induced chronic physical disability and social psychological distress.
RESUMO
PURPOSE: To evaluate the diagnostic performance of contrast-enhanced (CE) ultrasound using Sonazoid (SNZ-CEUS) by comparing with contrast-enhanced computed tomography (CE-CT) and contrast-enhanced magnetic resonance imaging (CE-MRI) for differentiating benign and malignant renal masses. MATERIALS AND METHODS: 306 consecutive patients (from 7 centers) with renal masses (40 benign tumors, 266 malignant tumors) diagnosed by both SNZ-CEUS, CE-CT or CE-MRI were enrolled between September 2020 and February 2021. The examinations were performed within 7 days, but the sequence was not fixed. Histologic results were available for 301 of 306 (98.37%) lesions and 5 lesions were considered benign after at least 2 year follow-up without change in size and image characteristics. The diagnostic performances were evaluated by sensitivity, specificity, positive predictive value, negative predictive value, and compared by McNemar's test. RESULTS: In the head-to-head comparison, SNZ-CEUS and CE-MRI had comparable sensitivity (95.60 vs. 94.51%, P = 0.997), specificity (65.22 vs. 73.91%, P = 0.752), positive predictive value (91.58 vs. 93.48%) and negative predictive value (78.95 vs. 77.27%); SNZ-CEUS and CE-CT showed similar sensitivity (97.31 vs. 96.24%, P = 0.724); however, SNZ-CEUS had relatively lower than specificity than CE-CT (59.09 vs. 68.18%, P = 0.683). For nodules > 4 cm, CE-MRI demonstrated higher specificity than SNZ-CEUS (90.91 vs. 72.73%, P = 0.617) without compromise the sensitivity. CONCLUSIONS: SNZ-CEUS, CE-CT, and CE-MRI demonstrate desirable and comparable sensitivity for the differentiation of renal mass. However, the specificity of all three imaging modalities is not satisfactory. SNZ-CEUS may be a suitable alternative modality for patients with renal dysfunction and those allergic to gadolinium or iodine-based agents.

Diabetic retinopathy (DR) is a complication of diabetes with a complex pathophysiology and multiple factors involved. Recently, it has been found that the upregulation of the renin-angiotensin-aldosterone system (RAAS) leads to overexpression of angiotensin II (Ang II), which induces oxidative stress, inflammation, and angiogenesis in the retina. Therefore, RAAS may be a promising therapeutic target in DR. Notably, RAAS inhibitors are often used in the treatment of hypertension. Still, the potential role and mechanism of DR must be further studied. In this review, we discuss and summarize the pathology and potential therapeutic goals of RAAS in DR.

The development of modern omics technology has facilitated in-depth research on many disciplines in the field of medicine. For instance, the introduction of omics-related technology has facilitated research on the mechanism of formula's action and led to the innovative development of sophisticated pharmacological analysis methods. However, in general, the previous ideas are only limited to the application level, failing to integrate with the discipline connotation of formulaology. Furthermore, they are unable to fulfill their potential role in the future evolution of formulaology and steer comprehensive research on the clinical efficacy and safety of formulas. We should not forget our origins, which are compatible with other countries, and embrace the future. Therefore, this paper proposes the three essentials of "holism, macro, and practice" to investigate the future direction of high-quality development in fangjiomics.

An elderly female patient with left pyelonephritis developed worsening left flank pain, hypotension and a drop in haemoglobin (Hb) from 97 g/L to 67g/L on the third day of her admission. There was no recent trauma, history of coagulopathy or risk factors for renal malignancy or vascular disease.A contrasted CT scan of the kidneys revealed a 3.8 cm left renal subcapsular haematoma with no active contrast extravasation. Her atraumatic subcapsular haematoma fulfils two out of three clinical features of Lenk's triad (acute flank pain, hypovolaemic shock), suggestive of Wunderlich syndrome. Urine and blood cultures grew Klebsiella pneumoniae and she was managed conservatively with culture-directed antibiotics, fluids and blood products.Wunderlich syndrome is a rare complication of pyelonephritis and should be considered in patients with pyelonephritis who develop acute severe flank pain, Hb drop and haemodynamic instability. Appropriate medical and surgical therapies need to be instituted early to ensure good outcomes.

ETHNOPHARMACOLOGICAL RELEVANCE: Qiteng Xiaozhuo Granules (QTXZG), a traditional Chinese medicine prescription, is widely acknowledged for its therapeutic efficacy and lack of discernible toxicity in clinical practice, substantiating its potential in the treatment of chronic glomerulonephritis (CGN). Nevertheless, the specific effectiveness and underlying mechanisms of QTXZG remain insufficiently explored. AIM OF THE STUDY: The purpose of this study was to explore the mechanism of the QTXZG in the treatment of CGN via targeting autophagy based on serum pharmacochemistry, network pharmacology, and experimental validation. METHODS: Serum samples from SD rats orally administered QTXZG were analyzed using UPLC-QE/MS to identify contained compounds. Network and functional enrichment analyses elucidated QTXZG's targets and biological mechanisms. Reliability was ensured through molecular docking, in vivo and in vitro experiments. RESULTS: After oral administration of QTXZG, 39 enriched compounds in serum samples collected 1 h later were identified as potential active agents, with 508 potential targets recognized as QTXZG-specific targets. Through integration of various databases, intersection analysis of QTXZG targets, CGN-related genes, and autophagy-related targets identified 10 core autophagy-related targets for QTXZG in CGN. GO and KEGG analyses emphasized their roles in autophagy, inflammation, and immune processes, particularly emphasizing the enrichment of the AMPK/mTOR signaling pathway. Molecular docking results demonstrated strong binding affinities between QTXZG's key compounds and the predicted core targets. In animal experiments, QTXZG was found to ameliorate renal tissue damage in CGN model mice, significantly reducing serum creatinine (Scr) and blood urea nitrogen (BUN) levels. Importantly, both animal and cell experiments revealed QTXZG's ability to decrease excessive ROS and inflammatory factor release in mesangial cells. Furthermore, in vitro and in vivo experiments confirmed QTXZG's capacity to upregulate Beclin1 and LC3II/I expression, decrease p62 expression, and induce CGN autophagy through modulation of the AMPK/mTOR pathway. CONCLUSIONS: This study indicated that QTXZG can induce autophagy in CGN by affecting the AMPK/mTOR pathway, and induction of autophagy may be one of the possible mechanisms of QTXZG's anti-CGN.

Objective To analyze the incidence and risk factors of hypothermia in elderly patients with malnutrition during proximal femoral nail antirotation(PFNA)internal fixation under general anesthesia.Methods A total of 139 elderly patients underwent PFNA internal fixation under general anesthesia were selected,and the nutritional status scores 1 day before surgery ranged from 0 to 11 points.Univariate and multivariate Logistic binary regression analysis was performed to analyze the related factors that may lead to intraoperative hypothermia.Results Among 139 elderly patients with preoperative nutritional scores of 0 to 11 points,79 cases(56.83%)developed intraoperative hypothermia.The results of univariate and multivariate Logistic binary regression analysis suggested that age≥75 years old,mini nutritional assessment short form(MNA-SF)nutritional score 0 to 7 points,BMI<18.5 kg/m2,duration of general anesthesia≥2 hours,intraoperative flushing fluid volume≥1 000 mL and intraoperative fluid volume≥1 000 mL were the risk factors for the occurrence of intraoperative hypothermia in elderly patients(OR>1,P<0.05).The use of warm blanket insulation was the protective factor against the occurrence of intraoperative hypothermia(OR<1,P<0.05).Conclusion The incidence of intraoperative hypothermia during PFNA internal fixation under general anesthesia in elderly patients with mainutrition before operation is high,and patients with poor nutritional status are more likely to develop intraoperative hypothermia.Patients with older age,poor nutritional status,lower BMI,longer duration of general anesthesia,and more intraoperative flushing fluid volume and intraoperative fluid volume are likely to lead to intraoperative hypothermia.The use of warm blanket can reduce the incidence of intraoperative hypothermia.
RESUMO
BACKGROUND: To assess the relationship between novel insulin resistance (IR) indices and the presence and severity of diabetic retinopathy (DR) in patients with type 2 diabetes. METHODS: This is a cross-sectional study involving 2211 patients. The study outcomes were DR events. The study exposures were IR indices including estimated glucose disposal rate (eGDR), natural logarithm of glucose disposal rate (lnGDR), metabolic insulin resistance score (METS-IR), triglyceride glucose index-body mass index (TyG-BMI), triglyceride glucose index-waist-to-hip ratio (TyG-WHR), and triglyceride/high-density lipoprotein cholesterol(TG/HDL-c ratio). We used binary and multivariate ordered logistic regression models to estimate the association between different IR indices and the presence and severity of DR. Subject work characteristic curves were used to assess the predictive power of different IR indices for DR. RESULTS: DR was present in 25.4% of participants. After adjusting for all covariates, per standard deviation (SD) increases in eGDR (ratio [OR] 0.38 [95% CI 0.32-0.44]), lnGDR (0.34 [0.27-0.42]) were negatively associated with the presence of DR. In contrast, per SD increases in METS-IR (1.97 [1.70-2.28]), TyG-BMI (1.94 [1.68-2.25]), TyG-WHR (2.34 [2.01-2.72]) and TG/HDL-c ratio (1.21 [1.08-1.36]) were positively associated with the presence of DR. eGDR was strongly associated with severity of DR. Of all variables, eGDR had the strongest diagnostic value for DR (AUC = 0.757). CONCLUSIONS: Of the six IR indices, eGDR was significantly associated with the presence and severity of DR in patients with type 2 diabetes. eGDR has a good predictive value for DR. Thus, eGDR maybe a stronger marker of DR.
