ObjectiveTo assess the relapse rate， clinical efficacy， and safety of a traditional Chinese medicine （TCM） sequential syndrome differentiation protocol for frequently relapsing/steroid-dependent nephrotic syndrome （FRNS/SDNS） in children. MethodsA total of 151 children with FRNS/SDNS treated in the First Affiliated Hospital of Henan University of Chinese Medicine from December 2020 to June 2024 were randomized into an observation group （77 cases） and a control group （74 cases）. Both groups received Western medicine （prednisone tablets and tacrolimus capsules）. In addition， the observation group additionally underwent TCM sequential syndrome differentiation and the control group received 1/10 of the TCM dose. The 6-month intervention was followed by a 12-month follow-up， totaling 18 months of observation across seven time points （before treatment and after 1， 2， 4， 24， 52， 76 weeks of treatment）. The evaluation was carried out based on the following indicators. ① The relapse rates were mainly recorded after 24， 52， 76 weeks of treatment. ② The efficacy was evaluated based on the clinical remission rates after 1， 2， 4 weeks of treatment， the time to proteinuria clearance， the levels of 24-hour urine total protein （24-h UTP）， serum total protein （TP）， serum albumin （ALB）， cholesterol （CHO）， and triglycerides （TG） and the TCM symptom scores before treatment and after 24 weeks of treatment. ③ The treatment safety was evaluated based on blood routine and levels of liver enzymes， renal function indicators and blood glucose （Glu） before treatment and after 24 weeks of treatment. Results① Relapse rate： After 24 weeks of treatment， no significant difference in relapse rate was found between the two groups. The observation group showed lower relapse rates than the control group after 52 weeks of treatment ［24.2% （16/66） vs. 52.5% （31/59）， χ²=10.634， P<0.01］ and 76 weeks of treatment ［42.4% （28/66） vs. 74.6% （44/59）， χ²=13.186， P<0.01］ than the control group. ② Efficacy indicators： The two groups showed no significant difference in remission rate after 1 week of treatment. The observation group demonstrated higher remission rates after 2 weeks of treatment ［88.2% （67/76） vs. 74.0% （54/73）， Z=-1.999， P<0.05］ and 4 weeks of treatment ［94.7% （72/76） vs. 82.2% （60/73）， Z=-2.3589， P<0.05）. In addition， the observation group had shorter time to proteinuria clearance （P<0.01）. After treatment， both groups showed declined 24 h-UTP， CHO， TG， and TCM symptom scores and elevated TP and ALB levels （P<0.01）， and the observation group had lower CHO， TG， and TCM symptom scores and higher TP and ALB than the control group （P<0.05）. ③ Safety indicators： After treatment， both groups showed declined white blood cell count （WBC）， red blood cell count （RBC）， hemoglobin （HB）， and alanine aminotransferase （ALT） （P<0.05， P<0.01） and elevated Glu （P<0.01） and blood urea nitrogen （BUN） （P<0.05）. After 24 weeks of treatment， none of WBC， RBC， HB， PLT， ALT， AST， BUN， Cr or Glu had significant differences between groups. Moreover， the incidence of adverse reactions showed no significant difference between the two groups. ConclusionThe TCM sequential syndrome differentiation protocol effectively reduces the relapse rate， improves the remission rate， shortens the time to proteinuria clearance， raised serum protein levels， lowers blood lipid levels， and alleviates symptoms， demonstrating good clinical safety in children with FRNS/SDNS.

OBJECTIVE: To observe the effects of Tongdu Tiaoshen acupuncture (for unblocking the obstruction in the governor vessel and regulating the spirit) on depression-like behavior and the hippocampal Endophilin A1/reactive oxygen species (ROS) pathway in the chronic unpredictable mild stress (CUMS) model rats, and explore the mechanism of this therapy for depression. METHODS: Forty-eight male SD rats of SPF grade were randomly divided into a normal group (n=12) and a modeling group (n=36). In the modeling group, CUMS was performed to establish depression model. The successfully-modeled rats were randomized into a model group, a Tongdu Tiaoshen acupuncture group (referred to as the acupuncture group), and a fluoxetine group, with 12 rats in each group. In the acupuncture group, "Baihui" (GV20), "Shenting" (GV24), "Shuigou" (GV26) and "Dazhui" (GV14) were stimulated with acupuncture. This intervention measure was delivered once a day, continuously for 6 days; it was discontinued on day 7 and was completed in 28 days. In the fluoxetine group, intragastric administration was done with fluoxetine solution (2.1 mg/kg), once a day, and for 28 consecutive days. Before and after modeling, and after intervention completion, the body mass, sucrose preference rate and the total distance of movement and the boxes of horizontal crossing in the open field experiment were observed in each group. After intervention, using HE staining, the hippocampal neuron morphology was observed; using Nissl staining, the hippocampal Nissl body number was counted. The hippocampal mitochondria was observed under transmission electron microscopy. The average fluorescence intensity of ROS in hippocampal was determined using flow cytometry. With Western blot method, the protein expression of Endophilin A1, growth associated protein 43 (GAP-43), and brain-derived neurotrophic factor (BDNF) in hippocampal was detected; and with RT-qPCR method, the mRNA expression of Endophilin A1, GAP-43, and BDNF was recorded. Using the immunofluorescence, the average fluorescence intensity of Endophilin A1, GAP-43, and BDNF in hippocampal tissue was determined. RESULTS: Compared with the normal group, in the model group, the body mass, sucrose preference rate, and the total distance of movement and the boxes of horizontal crossing in the open field experiment decreased (P<0.01); the hippocampal neuronal structure was unclear, the matrix was relatively loose, and the number of Nissl body decreased (P<0.01); mitochondrial structure was disarranged, the outer membrane was ruptured, mitochondrial cristae was irregular or missed; the average fluorescence intensity of ROS in hippocampal tissue, the protein and mRNA expression and the average fluorescence intensity of Endophilin A1 in hippocampal tissue increased (P<0.01), while the protein and mRNA expression of GAP-43 and BDNF and its average fluorescence intensity decreased (P<0.01). Compared with the model group, the acupuncture group and the fluoxetine group showed the increase in body mass, sucrose preference rate, the total distance of movement and the boxes of horizontal crossing in the open field experiment (P<0.05, P<0.01); the hippocampal neuronal structure became relatively clear, the matrix was relatively dense, and the number of Nissl body was elevated (P<0.01); mitochondrial structure got normal and disarranged slightly, the average fluorescence intensity of ROS in hippocampal tissue, the protein and mRNA expression and the average fluorescence intensity of Endophilin A1 in hippocampal tissue were reduced (P<0.01), while the protein and mRNA expression of GAP-43 and BDNF and the average fluorescence intensity rose (P<0.01, P<0.05). Compared with the fluoxetine group, the acupuncture group presented the increase in the average fluorescence intensity of ROS, the protein expression and the average fluorescence intensity of Endophilin A1, the protein expression of GAP-43 and the mRNA expression of BDNF (P<0.01, P<0.05), and the decrease of the protein expression and the average fluorescence intensity of BDNF, the mRNA expression of Endophilin A1, and the average fluorescence intensity of GAP-43 (P<0.01, P<0.05). CONCLUSION Tongdu tiaoshen acupuncture alleviates depression-like behaviors in CUMS model rats and protects hippocampal neurons, which may be related to suppressing Endophilin A1/ROS signaling pathway and attenuating oxidative stress reactions.

Objective To investigate the clinical phenotypic characteristics of a pedigree with congenital tooth agenesis(CTA)and identify the pathogenic gene using whole-exome sequencing(WES),aiming to confirm the disease-causing mutation site,explore its potential impact on protein structure and function,and provide new insights for the diagnosis of CTA.Methods The study focused on a pedigree with congenital absence of premolars.Blood samples were collected from pedigree members,and genomic DNA was extrac-ted.Potential pathogenic mutations were screened using WES and bioinformatics analysis.Candidate mutations were validated by Sanger sequencing.Gene Ontology(GO)functional annotation and KEGG pathway enrichment analysis were performed on co-expressed genes of the candidate gene.Results Clinical examination revealed that all four members of the family were patients with missing premolar teeth.WES identified two novel mutations in the TTN gene(c.94145G＞A and c.105406C＞T)in all affected family members.Sanger sequencing confirmed co-segregation of these mutations with the disease phenotype in the pedigree.Bioinformatics analysis indicated that Ttn was highly expressed during craniofacial development in mouse embryos.Enrichment analysis demonstrated that Ttn co-ex-pressed genes were significantly enriched in the extracellular matrix(ECM)receptor interaction and PI3K/Akt signaling pathway.Conclusion This study suggests that TTN is a potential pathogenic gene for congenital premolar agenesis in this pedigree.

Objective:To investigate the effect of bronchoalveolar lavage fluid(BALF)cytology examination combined with lymphocyte immunoassay on clinical outcome of critically ill patients with stroke-associated pneumonia(SAP).Methods:One hundred and fifty-six critically ill patients with SAP admitted to Department of Respiratory and Critical Care Medicine of the Second People's Hospital of Weifang from September 2021 to June 2022 were selected,and randomly divided into a study group and a control group,with 78 cases in each group.Control group was treated with conventional pulmonary infection,and study group added bronchoscopic alveolar lavage treatment based on the treatment of control group,and the anti-infection treatment regimen was adjusted according to the results of BALF lymphocyte immunoassay.Clinical improvement rates,clinical symptom scores,serum inflammatory factors[procal-citonin(PCT),C-reactive protein(CRP),TNF-α],peripheral blood lymphocyte subsets(CD3+T,CD4+T,CD8+T)levels,treatment condition,in-hospital mortality and incidence of acute respiratory distress syndrome(ARDS)between the two groups were compared.Results:Clinical improvement rates were higher in study group(44.87%,58.97%,91.03%,97.44%)than that in control group(26.92%,42.31%,78.21%,88.46%)at 3 d,5 d,7 d and 10 d of treatment(P<0.05);serum PCT,CRP and TNF-α levels were lower in study group than that in control group after 10 d of treatment(P<0.05);peripheral blood CD3+T,CD4+T,CD8+T levels were higher in study group than that in control group after 10 d of treatment(P<0.05).CPIS and CURB-65 scores were lower in study group than that in control group after 10 d of treatment(P<0.05);duration of antimicrobial drug use,duration of mechanical ventilation,and length of hospital stay were shorter in study group than that in control group(P<0.05);in-hospital mortality rate(7.69%)and inci-dence of ARDS(5.13%)were lower in study group than that in control group(19.23%,15.38%)(P<0.05).Conclusion:Optimized anti-infection treatment plan based on BALF cytology examination combined with lymphocyte immunoassay can significantly improve clinical efficacy of critically ill patients with SAP,and help to promote recovery and improve the prognosis of patients.

Objective:To analyze the epidemiological characteristics of cases involving monkey injuries at medical institutions surrounding Qianlingshan Park in Guiyang City, and to provide a reference basis for preventive measures to reduce monkey injuries and standardized post-exposure treatment.Methods:A retrospective cross-sectional study was conducted, collecting 1 900 cases of monkey-induced injuries in Qianlingshan Park treated at the outpatient clinic of Guizhou Provincial Center for Disease Control and Prevention and the Department of Surgery at Qianling Hospital, Guiyang City, from 2021 to 2024. Statistical analysis was performed using Pearson′s chi-square test.Results:Total of 1 900 cases of monkey-related injuries in Qianlingshan Park were collected from 2021 to 2024. The exposure time distribution exhibited significant seasonality, with 48.58% of cases occurring during July and August, totaling 923 cases, indicating a peak in the summer. There were 774 male patients and 1 126 female patients, with a ratio of 1∶1.45.and significant differences were observed between different age groups and genders (χ2=195.00, P<0.001), with the highest number of cases occurring in the 0-9 and 20-29 age groups, accounting for 22.05%(419 cases) and 21.79%(414 cases), respectively. The upper limbs were the most common injury site, accounting for 50.84% of the total cases(966 cases in total), with significant differences between gender and injury location (χ2=22.00, P<0.001), Among females, the proportion of injuries to the upper and lower limbs (30.11% and 16.47%, respectively) was higher than that among males (20.74% and 8.63%, respectively). The majority of injuries were classified as Grade Ⅲ, making up 57.38% of cases(1 069 cases in total). Self-treatment after exposure was the most common approach(60.44%), with significant differences observed between wound severity and treatment method (χ2=6.90, P=0.032), Patients with Grade Ⅱ and Grade Ⅲ wounds were more likely to choose self-management (26.84% and 33.23%, respectively) than outpatient management (15.14% and 24.15%). Approximately 98.05% (1 863 cases) of monkey-injured patients had received rabies vaccinations. Conclusions:This study analyzes monkey-related injuries in Qianlingshan Park from 2021 to 2024, clarifying the temporal distribution of injuries, demographic characteristics, injury sites, and treatment methods. The findings provide references for optimizing human-monkey conflict management and the prevention and control of zoonotic diseases in urban ecological parks.

Objective:To analyze risk factors associated with false-positive results of quantitative fecal immunochemical testing (FIT), evaluate its performance for detecting advanced colorectal neoplasia across different subgroups, and explore the optimal positivity thresholds for each subgroup.Methods:Individuals who participated in the Zhejiang Colorectal Cancer Screening Program in 2020-2021, completed questionnaire-based risk assessment and quantitative FIT for initial screening, and undertook colonoscopy for confirmed diagnosis were included in this study. The information of individuals, including demographic characteristics, lifestyles, history of diseases, and family history of colorectal cancer (CRC), was collected by using questionnaires. The diagnostic outcomes of the individuals were obtained through colonoscopy and pathological examination. Multivariate logistic regression analyses were conducted to identify factors associated with false-positive FIT results. The optimal threshold of FIT was determined based on the receiver operating characteristic (ROC) curve and 10-fold cross-validation. The effectiveness of FIT screening in different subgroups was compared using the unified threshold of 100 ng/ml or optimal positivity thresholds.Results:There were 25 874 individuals included in the analysis, with 14 694 (56.79%) having fecal hemoglobin concentrations ≥100 ng/ml. A total of 3 830 advanced adenoma cases (14.80%) and 362 CRC cases (1.40%) were identified. Age below 60 years old, females, underweight, smoking, drinking, use of nonsteroidal anti-inflammatory drugs, no family history of CRC, no history of intestinal disease, no history of hypertension, and physical inactivity were associated with an elevated risk of false-positive results in FIT ( P<0.05). Compared to the predetermined threshold of 100 ng/ml, the false positive rate (FPR) of quantitative FIT decreased from 52.3% to 37.3% in all individuals, and decreased by more than 20% in females, individuals with normal weight, smokers, and those without a history of intestinal disease when adopting the optimal threshold (all P<0.001). Conclusion:The risk of false-positive results in quantitative FIT varies across different subgroups. Adopting the optimal thresholds could improve the specificity and reduce the FPR of quantitative FIT for CRC screening.

Objective:To evaluate the efficacy and safety of baricitinib combined with ruxolitinib cream in the treatment of progressive nonsegmental vitiligo.Methods:Clinical data were retrospectively collected from patients with progressive nonsegmental vitiligo in Boao Super Hospital. All the patients were treated with oral baricitinib daily (2 mg/day for patients weighing ≤ 50 kg; 4 mg/day for those > 50 kg) in combination with topical application of ruxolitinib cream twice daily for 24 consecutive weeks. Disease severity was assessed using the facial vitiligo area scoring index (F-VASI) and total body VASI (T-VASI) at baseline, week 12, and week 24. Adverse reactions were monitored throughout the treatment course.Results:Six patients with progressive nonsegmental vitiligo were collected, including 3 males and 3 females, aged 26 - 42 years, with the disease duration ranging from 0.5 to 25 years. At week 12, 3 patients achieved a 50% ~ < 75% improvement in facial vitiligo lesions (F-VASI 50), 1 patient achieved F-VASI 75 (75% ~ < 90% improvement), and 1 patient achieved T-VASI 50; at week 24, 4 patients achieved F-VASI 50, 1 patient achieved F-VASI 75, 1 patient achieved F-VASI 90 (≥ 90% improvement), and 3 patients achieved T-VASI 50. During the treatment, upper respiratory infection occurred in 1 patient, acne in 1 patient, pruritus in 2 patients, elevation of total cholesterol levels in 2 patients, and increase of high-density lipoprotein levels in 2 patients. No severe adverse events were observed during the treatment.Conclusion:The combination therapy with baricitinib and ruxolitinib cream may have potential efficacy and safety in the treatment of progressive nonsegmental vitiligo.

Objectives:To understand the awareness of HIV pre-exposure prophylaxis and post-exposure prophylaxis (PrEP/PEP) and related factors among female sex workers (FSWs) in Zhejiang Province to provide a reference for promoting PrEP/PEP.Methods:From April to July 2023, a questionnaire survey was conducted at the surveillance posts of prostitutes in 17 counties (cities and districts) in Zhejiang Province. The sample size of each post was at least 400 FSWs, and the information on social demography, sexual behavior, AIDS knowledge, prevention services, and detection were collected.Results:A total of 6 899 FSWs were surveyed. Most of them were ≥30 years old (57.7%), had secondary school education or below (61.8%), and had worked locally for ≥12 months (52.6%). The prevalence of HIV PrEP and PEP awareness among FSWs was 52.0% (3 589/6 899) and 58.6% (4 045/6 899), respectively. Multivariate logistic regression analysis showed that the negative related factors of awareness of PrEP/PEP among FSWs included age ≥30 years, local working time <6 months, and condom use during commercial sex in the last 1 month. The positive related factors of awareness of PrEP/PEP among FSWs included marital status was married or cohabiting, aware of HIV/AIDS knowledge, working in medium or high-end venues, finding clients primarily online in the past 6 months, receiving HIV prevention services in the past year, and having self-tested for HIV in the past year.Conclusions:The overall awareness of PrEP/PEP was relatively low among FSWs in Zhejiang Province. Efforts should be made to strengthen the publicity and education of PrEP/PEP, especially for those who are older and more mobile and working in low-end venues, combined with HIV prevention services to increase the use of PrEP/PEP.

In the general population, obesity (high BMI) is often considered as an important risk factor for many diseases and premature death. However, in patients with a certain disease, the risk of death in people with obesity was lower than that in people with normal weight. This abnormal correlation has caused widespread discussion, and different explanations have been given by physiology and epidemiology. Based on causal inference theory, this study used directed acyclic graphs to introduce the collision bias (also called collision-stratification bias). Through example demonstrations, this study explored whether and why the abnormal correlation between obesity and higher survival rates in patients with hyperglycemia exists. Finally, it was concluded that this abnormal correlation among patients with a certain disease (e.g., hyperglycemia in the current analysis) was partly or even totally caused by collider bias.
