ObjectiveTo explore the effect of Shenge Bushen Capsules （SBC） on sexual development in normal 3-week-old mice. MethodsThe experiment consisted of two parts. In the first part， mice were divided into four groups： The control group and the low， medium， and high-dose SBC groups （234.7， 469.4， 938.7 mg·kg^-1， respectively）. In the second part， mice were divided into four groups： Control group， Pseudostellariae Radix polysaccharide （PRP） group， total flavonoids group， and SBC group， all receiving a dose of 469.4 mg·kg^-1. After 7 days of administration， the vaginal opening of female mice and the descent of testes and scrotum in male mice， as well as the ovarian and testicular organ indices， were observed. After 4 weeks of administration， female and male mice were housed together for 2 days， and the pregnancy rate of females was monitored. After delivery， the pregnant female mice continued receiving the treatment for 4 weeks， and the sexual development of their offspring， including vaginal opening， testicular descent， and organ indices of ovaries and testes， was observed. Serum sex hormones were measured by enzyme-linked immunosorbent assay （ELISA）， and the expression of gonadotropin-releasing hormone （GnRH） and growth hormone （GH） proteins in the hypothalamus was assessed by Western blot. ResultsCompared with the control group， there was no significant effect on the vaginal opening of female mice or the descent of testes in male mice after 7 days of SBC administration. After 4 weeks of administration， the pregnancy rate in the low-dose group was significantly reduced （P<0.05）， but no significant effects were observed in the other groups. The three doses of SBC did not significantly affect the ovarian or testicular organ indices， and there was no significant upregulation in the expression of GnRH or GH in the hypothalamus. The primary component of SBC， Pseudostellariae Radix polysaccharide， significantly reduced the vaginal opening in female mice after 7 days of administration （P<0.05）. After 4 weeks， the serum estradiol levels of non-pregnant female mice were decreased （P<0.05）， but there was no significant effect on the expression of GnRH or GH proteins in the hypothalamus of either male or female mice. Additionally， there were no significant effects on precocious puberty indicators， such as vaginal opening and testicular descent， in the offspring mice. ConclusionSBC does not significantly promote precocious puberty in young mice， and it does not have any noticeable effects on the pregnancy rate of adult mice or the sexual development of their offspring.

Objective　To analyze the clinical characteristics and prognostic factors for clinical cure in chronic hepatitis B virus (HBV) infected patients with pegylated interferon-α-2b (PEG-IFN-α-2b) based therapy. Methods　This is a retrospective study. Chronic HBV infected patients receiving PEG-IFN-α-2b therapy were enrolled in Yuncheng Central Hospital affiliated to Shanxi Medical University between August 2020 and November 2023. Treatment-naïve patients received PEG-IFN-α-2b monotherapy, while nucleoside (acid) analogs (NAs)-experienced patients received PEG-IFN-α-2b add-on therapy. The study endpoint was hepatitis B surface antigen (HBsAg) negative in accompany with HBV DNA below the detection limit (course of treatment < 48 weeks) or treatment for 48 weeks. The general characteristics, virological variables, blood routine test, and liver function of patients were collected at baseline and study endpoint. Student’s t test or Mann-Whitney U test was used for comparison. The prognostic factors of clinical cure were examined using univariate and multivariate stepwise logistic regression models. Results　A total of 61 chronic HBV infected patients were enrolled, including 39 males and 22 females. The age were (39.13±7.53) years. Twenty-one cases were treatment-naïve, while 40 patients were NAs-experienced. Nineteen cases were positive for HBV DNA at baseline. The baseline HBsAg levels were 211.30(50.93, 2 110.00) IU/mL. Thirty-four patients achieved clinical cure at the study endpoint with 25.50 weeks of median course of PEG-IFN-α-2b treatment. Twenty-seven patients did not achieve clinical cure at the study endpoint, and the course of treatment was 48 weeks. Clinical cure group had significant lower baseline HBsAg level when compared with non-clinical cure group [78.66(19.54, 204.60) IU/mL vs 2 078.00(442.20, 4 237.00) IU/mL, P<0.001]. At the study endpoint, the white blood cell, platelet, red blood cell, hemoglobin levels were lower than those in baseline (P<0.05), while alanine aminotransferase and asparatate aminotransferase levels were higher than those in baseline (P<0.05). There were no remarkable differences in blood routine tests or liver function between clinical cure and non-clinical cure group at either baseline or study endpoint (P>0.05). Baseline low HBsAg level was a predictor for clinical cure in patients receiving PEG-IFN-α-2b therapy (OR=0.998, 95%CI: 0.998-0.999). No severe adverse events were happened during therapy. Conclusion　PEG-IFN-α-2b-based therapy was well-tolerant, and could achieve high rate of clinical cure in chronic HBV-infected patients who had low baseline HBsAg level.

Objective This study aims to explore the associations between threat and deprivation childhood traumas and dysfunctional attitudes among patients with major depressive episode,based on the dimensional model of adversity and psychopathology(DMAP).Methods Data from 970 patients with major depressive episode were collected and categorized based on the childhood trauma questionnaire-short form(CTQ-SF)scores into no trauma(426),threat-only(86),deprivation-only(210),and mixed groups(248).Cognitive distortions were assessed using the dysfunctional attitudes scale(DAS),with scores above the upper quartile indicating significant distortions.Multifactorial logistic regression analysis was employed to examine the association between threat and deprivation and dysfunctional attitudes.Results There were significant differences in the proportion of cognitive distortions among the no trauma,threat-only,deprivation-only,and mixed groups(19.25% vs.30.23% vs.20.00% vs.35.89%,P<0.001),with differences across all dimensions(P≤0.001).Multifactorial logistic regression revealed a positive correlation between threat and overall cognitive distortions(OR=2.031,P<0.001),and specific positive correlations with dimensions such as vulnerability(OR=1.709,P<0.001),appeal and repulsion(OR=2.088,P<0.001),perfectionism(OR=2.321,P<0.001),compulsivity(OR=1.765,P=0.001),approval seeking(OR=1.837,P<0.001),dependency(OR=1.554,P=0.006),and autonomous attitudes(OR=1.864,P<0.001).In contrast,deprivation was only positively correlated with the cognitive philosophy dimension(OR=1.495,P=0.015).Conclusion Childhood trauma is closely associated with dysfunctional attitudes in patients with major depressive episode.Threat correlates positively with cognitive distortions in all dimensions except cognitive philosophy,whereas deprivation correlates only with the cognitive philosophy dimension.

Objective To investigate the efficacy and safety of intravenous thrombolysis with low-dose and standard-dose recombinant tissue plasminogen activator(rt-PA)in the elderly patients(aged over 80 years)with acute ischemic stroke(AIS).Methods A total of 201 elderly patients with AIS treated at Tianjin Fourth Central Hospital from February 2019 to February 2023 were prospectively included and randomly assigned to the rt-PA low-dose group(n=93,0.6 mg/kg)and rt-PA standard-dose group(n=108,0.9 mg/kg).The incidence of intra-cranial hemorrhage,symptomatic intracranial hemorrhage,fatal intracranial hemorrhage,neurologic deterioration within 7 days and mortality within 90 days were observed to evaluate the safety.The neurologic improvement rate and good prognosis rate at 90 days were used to evaluate the effectiveness.A stratified analysis of 90-day outcomes was performed based on stroke severity and age.Results The incidence of intracranial hemorrhage,symptomatic intracranial hemorrhage and fatal intracranial hemorrhage within 7 days in rt-PA low-dose group was lower than that in rt-PA standard-dose group(P＜0.05).There were no statistically significant differences between the two groups concerning the residual safety index and the effectiveness index.The 90-day good prognosis rate of moderate stroke sub-group and of≥90 years of age sub-group in rt-PA low-dose group were both higher than that of rt-PA standard-dose group(P＜0.05).Conclusions For AIS patients with moderate stroke and aged over 90 years,intravenous thrombolytic therapy with rt-PA 0.6 mg/kg is recommended.

Objective:To investigate the prevalence of hyperuricemia (HUA) in Bozidun Kirghiz township of Xinjiang Aksu region, and to explore the risk factors for the occurrence of HUA in the local area.Methods:A cross-sectional survey study was conducted by randomly selecting 9 villages in Bozidun Kirgiz Township by the whole-group sampling method and questionnaire were distributed to the households. The questionnaire included: demographic information, history of past illness, personal history, and all subjects were measured for height, weight, blood pressure, abdominal circumference, etc. The diagnostic of HUA if the serum uric acid (SUA) level >420 μmol/L in men or >360 μmol/L in women. The incidences of HUA in different age, sex, food type and life style behavior were analyzed. T test, non-parametric test and Chi-square test were used to analyze the differences among the groups, and logistic regression was used to analyze the risk factors. Results:①A total of 2 138 subjects were surveyed, among which 68 patients were with HUA, the prevalence of HUA in Bozidun Kirghiz township, Aksu region in the general population was 3.18%(68/2 138); the prevalence rate in men was 4.60%(45/978), 45 patients were identified; and the prevalence rate in women was 1.98%(23/1 160), 23 patients were identified. The peak age of HUA in male and female patients was 51~60 years old. ②The prevalence of HUA was lower in those who consumed dairy products ( χ2=6.91, P=0.017), nuts ( χ2=8.43, P=0.038) and eggs ( χ2=7.38, P=0.023), and lower in those who consumed more. Different intake of cereals ( χ2=0.87, P=0.647), meat( χ2=0.82, P=0.662), vegetables and fruits( χ2=5.22, P=0.073) had no effect on the prevalence of HUA.③In terms of different life behaviors, the prevalence of HUA in men who had been smoking was higher than those who had never smoked (57.78%, 28.89%, 13.33%, χ2=8.16, P=0.017). In the relationship between drinking and HUA, the prevalence rates of male always drinking, ever drinking and never drinking were 80.00%, 11.11% and 3.89%, respectively, the difference was statistically significant ( χ2=6.67, P=0.038). ④Multi-factor logistic regression analysis showed that high BMI, old age, high TG, increased Cr and increased WBC were risk factors for the occurrence of HUA [ OR(95% CI)=1.13(1.04, 1.23), 1.03(1.00,1.05),1.39(1.00, 1.93), 1.03(1.02, 1.05), 1.27(1.07, 1.49), all P<0.05]. Conclusion:The prevalence of HUA in Bozidun Kirgiz township in Aksu prefecture of Xinjiang is lower than that in other areas with continental climate. High BMI, old age, high TG, increased Cr and increased WBC count are risk factors for the development of HUA .

Objective:To investigate the positivity rate and high titer of antinuclear antibody (ANA) and anti-dsDNA antibody in healthy Tajik, Kirgiz, and Han Chinese populations in Xinjiang.Methods:A total of 3 687 cases of Tajik residents, 2 140 cases of Kyrgyz residents, and 2 034 cases of Han residents were selected as the study subjects, and ANA and anti-dsDNA antibodies were detected and comparatively analyzed. Data were analyzed using SPSS 22.0 software with χ2 test. Results:The positive rate of ANA in Tajik group was 15.1% [(555/3 687), 10.2%(147/1 445) male, 18.2%(408/2 242) female], of which high titers accounted for 25.8%(143/555). It was 16.7%(357/2 140) in the Kyrgyz group [10.3% male(101/980), 19.4%(256/1 160) female], with high titers accounting for 14.8%; and in the Han group, the positivity rate was 16.6% [9.8%(70/720) male, 19.1%(267/1 314) female], with high titers accounting for 18.4%(62/1 337). There was no significant difference in ANA positivity rate among the three ethnic groups( χ2=3.64, P=0.162), but there were differences in the percentage of high titer of ANA in Tajik ethnic group compared with Han and Kyrgyz ethnic groups(25.8% vs. 18.4%, χ2=6.02, P=0.014; 25.8% vs.14.8%, χ2=14.71, P=0.001), which accounted for a high percentage. The highest number of ANA high titers in all three groups was in the age group of 51~60 years. The ANA karyotype with the highest percentage of high titers in the Tajik and Kyrgyz populations was granular, while it was homogeneous and in the Han it was homogeneous.The positive rate of anti-dsDNA antibody in the Tajik group was 0.71%(26/3 687), of which high titer accounted for 23.1%(6/126); in the Kyrgyz group, it was 0.75%(16/2 034), and high titer accounted for 31.3%(4/14); and in the Han group, the positive rate was 0.69%(14/2 034), of which high titer accounted for 28.6%(4/64), and there was no statistical significance of in the difference in the positive rate of anti-dsDNA antibody and the proportion of high titer among the three groups( χ2=0.06, P=0.972; χ2=0.37, P=0.832). Conclusion:The percentage of ANA and anti-dsDNA antibodies and high titers varied vary among the three ethnic groups in this study, and long-term follow-up is needed to monitor keep an eye on the incidence of autoimmune diseases in people with high autoantibody titers.

OBJECTIVE To explore the effects and potential mechanism of evodiamine on inflammatory response and apoptosis of epithelial cells in asthma model rats. METHODS SD rats were separated into control group， model group， evodiamine low-dose group （10 mg/kg）， evodiamine high-dose group （20 mg/kg）， dexamethasone group （positive control， 0.5 mg/kg）， epidermal growth factor （EGF） group [mitogen-activated protein kinase （MAPK） activator， 10 μg]， evodiamine high-dose+EGF group （20 mg/kg evodiamine+10 μg EGF）， with 10 rats in each group. Except for the control group， the other groups were sensitized by 3-point injection of 10% ovalbumin（OVA）-aluminium hydroxide mixture and stimulated by inhalation of 2%OVA nebulized liquid to establish an asthma model. The count of inflammatory cells （macrophages and lymphocytes） in bronchoalveolar lavage fluid （BALF） was detected in each group； pathological changes of lung tissue in rats were observed； the apoptosis of airway epithelial cells， the levels of serum inflammatory factors [tumor necrosis factor-α， interleukin-6 （IL-6） and IL-4]， the expressions of pathway-related proteins p38 MAPK， phosphorylated p38 MAPK （p-p38 MAPK）， signal transduction and transcription activating factor 1 （STAT1）] and apoptosis-related proteins [B cell lymphoma-2 （Bcl-2） and Bcl-2 associated X protein （Bax）] were all detected in lung tissue. RESULTS Compared with the control group， bronchial mucosal edema， thickening of alveolar septa and extensive infiltration of inflammatory cells were observed in the lung tissue of rats in the model group； the number of inflammatory cells， apoptosis rate of airway epithelial cells， the levels of inflammatory factors， p-38 MAPK/p-38 MAPK， and the protein expressions of Bax and STAT1 were increased significantly； the expressions of Bcl-2 protein and Bcl-2/Bax were reduced significantly （P＜0.05）. Compared with the model group， the pathological changes in lung tissues were alleviated to varying degrees in evodiamine low-dose and high-dose groups， and dexamethasone groups， and the above indicators were significantly reversed. However， the change trends of corresponding indicators in the EGF group were opposite to the above （P＜0.05）. EGF could significantly attenuate the effect of high-dose evodiamine on inflammatory response in asthmatic rats （P＜0.05）. CONCLUSIONS Evodiamine can relieve inflammatory reactions and inhibit the apoptosis of airway epithelial cells in asthmatic rats， the mechanism of which may be associated with inhibiting p38 MAPK/STAT1 signaling pathway.

Objective: To explore the association of tobacco/alcohol-excessive Internet usage and insufficient sleep with depressive symptoms among middle school students, so as to provide a reference for improving mental health of middle school students. Methods: In accordance with the cluster random sampling method, a total of 18 484 middle school students in Shanghai were surveyed from September to November 2022. Tobacco/alcohol-excessive Internet usage and sleep duration with depressive symptoms were assessed using the relevant scale items included in the questionnaire of Surveillance for Common Disease and Health Risk Factors among Students. The χ 2 test was used for inter group comparison, Logistic regression analysis and likelihood ratio test were used to analyze the independent and aggregated associations of tobacco/alcohol-excessive Internet use and insufficient sleep wiht depressive symptoms. Results: Self reported rates of tobacco/alcohol-excessive Internet usage, insufficient sleep and depressive symptoms among adolescents were 14.7%, 73.5% and 16.3%, respectively. Tobacco/alcohol-excessive Internet usage ( OR=2.69, 95%CI =2.44-2.97) and insufficient sleep ( OR=1.76, 95%CI =1.58-1.95) were associated with depressive symptoms ( P <0.05). Compared to middle school students with no tobacco/alcohol-excessive Internet usage and sufficient sleep, those with both tobacco/alcohol-excessive Internet usage and insufficient sleep showed the higher rate of depressive symptoms ( OR=4.71, 95%CI =4.08-5.44, P <0.05). Further stratified analysis results showed that, compared to the boys and the high school students, the separate and joint association of tobacco/alcohol-excessive Internet usage and insufficient sleep with depressive symptoms were more pronounced in the girls and the middle school students [ OR (95% CI ) for tobacco/alcohol-excessive Internet usage were 3.09 (2.68-3.56) and 4.74 (3.86-5.83), respectively; OR (95% CI ) for insufficient sleep were 1.86 (1.60-2.17) and 2.00 (1.58-2.53), respectively; and the OR (95% CI ) for the joint association were 6.05 (5.01-7.31) and 9.15 (6.98-11.99), respectively, P <0.05]. Conclusions Tobacco/alcohol-excessive Internet usage and insufficient sleep are associated with depressive symptoms in middle school students. Prevention and control strategies for adolescent mental health should be developed with consideration of health related behaviors, and also need to be tailored by focusing on gender and grade differences.
