Systemic lupus erythematosus (SLE) is an autoimmune disease accompanied by various complications, and the exact etiology remains unclear. Treatments for SLE encompass hormone therapy, plasma exchange and immunoadsorption, and targeted biological therapies. Berbamine (BBM), a cellular immunopotentiator with diverse biological functions, has not been reported to have immunomodulatory and therapeutic effects on SLE. The mice were divided into control group, model group, positive control group, low, medium and high BBM groups. In control group, C57BL/6J wild mice received intraperitoneal injection of saline. In model group, MRL/lpr lupus mice were treated with intraperitoneal injection of saline. In positive control group, MRL/lpr lupus mice received intragastric administration of hydroxychloroquine sulfate tablets [Plaquenil, 150 mg/(kg·d)]. In BBM groups, MRL/lpr lupus mice received intragastric administration of different concentration of BBM respectively [20 mg/(kg·d), 50 mg/(kg·d), 100 mg/(kg·d)]. After 8 weeks of treatment, blood was collected from the retro-orbital venous plexus, and ELISA was used to detect the levels of anti-double-stranded DNA (dsDNA) antibodies, antinuclear antibodies (ANA), and anti-small nuclear ribonucleoprotein/Sm (snRNP/Sm) antibodies. Spleen tissues were collected for analysis of Th1/Th2 ratio by flow cytometry. The RNA and protein of spleen were extracted, and the levels of T-box transcription factor T-bet and GATA3 (GATA binding protein 3) mRNA and protein were detected by qRT-PCR and Western blot. The proliferation of white blood cells in the blood was tested by blood routine test. The histopathological changes of kidneys of each group were detected by HE staining. Compared with the model group, the levels of ANA, anti-dsDNA, and anti-snRNP/Sm antibodies were significantly reduced in the BBM-treated groups. The Th1/Th2 ratio was significantly decreased in the model group, but reversed by BBM. Compared with the control group, T-bet expression was significantly downregulated, while GATA3 expression was significantly upregulated in the model group. After BBM intervention, T-bet expression significantly increased, while GATA3 expression decreased compared with the model group. The number of white blood cells significantly decreased in the model group, and increased in the BBM-treated groups. In the model group, the glomerular mesangial and endothelial cells showed significant hyperplasia, clear thrombus was observed in the dilated capillaries, and inflammatory cells infiltrated in the renal interstitium. In medium and high BBM groups, the infiltration of inflammatory cells and capillary thrombosis were significantly decreased. In conclusion, BBM exhibits certain immunomodulatory effects on SLE and promotes the proliferation of white blood cells.

PURPOSE: This study aims to identify the prevalence and risk factors of military training-related abdominal injuries and help plan and conduct training properly. METHODS: This questionnaire survey study was conducted from October 2021 to May 2022 among military personnel from 6 military units and 8 military medical centers and participants' medical records were consulted to identify the training-related abdominal injuries. All the military personnel who ever participated in military training were included. Those who refused to participate in this study or provided an incomplete questionnaire were excluded. The questionnaire collected demographic information, type of abdominal injury, frequency, training subjects, triggers, treatment, and training disturbance. Chi-square test and t-test were used to compare baseline information. Univariate and multivariate regression analyses were used to explore the risk factors associated with military training-related abdominal injuries. RESULTS: A total of 3058 participants were involved in this study, among which 1797 (58.8%) had suffered training-related abdominal injuries (the mean age was 24.3 years and the service time was 5.6 years), while 1261 (41.2%) had no training-related abdominal injuries (the mean age was 23.1 years and the service time was 4.3 years). There were 546 injured patients (30.4%) suspended the training and 84 (4.6%) needed to be referred to higher-level hospitals. The most common triggers included inadequate warm-up, fatigue, and intense training. The training subjects with the most abdominal injuries were long-distance running (589, 32.8%). Civil servants had the highest rate of abdominal trauma (17.1%). Age ≥ 25 years, military service ≥ 3 years, poor sleep status, and previous abdominal history were independent risk factors for training-related abdominal injury. CONCLUSION More than half of the military personnel have suffered military training-related abdominal injuries. Inadequate warm-up, fatigue, and high training intensity are the most common inducing factors. Scientific and proper training should be conducted according to the factors causing abdominal injuries.

OBJECTIVE: To investigate the clinical efficacy of Zhuangdan Yanshi Decoction combined with dapoxetine hydrochloride in the treatment of premature ejaculation with cholestasis and phlegm disturbance. METHODS: A total of 120 patients diagnosed with premature ejaculation and treated in the Andrology Outpatient Department of Shaanxi Provincial Hospital of Traditional Chinese Medicine from March to December in 2022 were selected and randomly divided into treatment group and control group, with 60 cases in each group. The incubation period of intravaginal ejaculation (IELT), the Diagnostic Scale of Premature Ejaculation (PEDT), the Premature Ejaculation Assessment Scale (PEP), the 5-item Sexual Function Evaluation of Chinese Premature Ejaculation Patients (CIPE-5) and the improvement of traditional Chinese medicine symptom scores were compared before and after the treatment. And the adverse reactions were recorded as well. RESULTS: A total of 105 cases were ultimately included, with 55 cases in the treatment group and 50 cases in the control group. Measurable improvements in IELT, PEDT scores, PEP scores, CIPE scores and TCM symptom scores had been found after treatment in both of two groups (P<0.05). Moreover, the improvement in the treatment group was superior to that in the control group (P<0.05). The total effective rate in the treatment group was 89.1%, which was higher than that(84%) in the control group, with no statistically significant difference between the two groups (P>0.05). The incidence of adverse reactions in the treatment group was 9.1%, which was 24% in the control group. There was significantly difference between two groups (P<0.05). CONCLUSION The combination therapy with Zhuangdan Yanshi Decoction and dapoxetine hydrochloride for premature ejaculation associated with cholestasis and phlegm disturbance syndrome is definite, and it can reduce the side effects of drugs, which is better than oral dapoxetine hydrochloride alone.

Objective To explore whether superovulation impairs the process of pregnancy establishment in mice by changing the intrauterine environment. Methods The implantation and pregnancy of superovulated and normal mice were compared. The superovulated mice were subjected to unilateral tubal ligation on day 0. 5 and blastocysts were transplanted to the other uterine horn on day 2. 5. The number of implantation sites of bilateral uterine horn was compared. The differences between preimplantation uteri of superovulated and normal pseudopregnancy mice were compared by tissue sections and high-throughput sequencing. Bioinformatics analysis was performed on the differentially expressed genes in two groups. Results Compared with the control group, the pregnancy rate of mice in the superovulation group decreased significantly. The number of implantation sites in the superovulation group was higher than the control. There was no significant difference in the pregnancy rate of the uterine horn between the control side and the transplanted side of the superovulated mice. The endometrium was thinned and the number of glands was reduced in superovulated pseudopregnancy mice. The gene expression patterns of preimplantation uterus in superovulation pseudopregnancy and normal pseudopregnancy mice were different. There were 1097 significantly differentially expressed genes, including 752 up-regulated genes and 345 down-regulated genes. Bioinformatics analysis showed that differentially expressed genes are mainly involved in biological processes, such as decidualization, response to progesterone, positive regulation of angiogenesis. They were mainly enriched in FoxO signaling pathway, cell cycle pathway and steroid biosynthesis pathway. Conclusion Superovulation impaired the process of establishing pregnancy and altered the gene expression patterns of biomarker of uterine receptivity in mice.

Objective: To explore the clinical efficacy and safety of modified Huqianwan in treatment of rheumatoid arthritis (RA) liver-kidney Yin deficiency syndrome, and investigate its possible mechanism. Method: A total of 184 patients with RA liver-kidney Yin deficiency syndrome were randomly divided into Chinese medicine group (62 cases), western medicine group (57 cases) and integrated Chinese and western medicine group (65 cases) according to the digital table method. The patients in Chinese medicine group were treated with Huqianwan; the patients in western medicine group were treated with methotrexate tablets and leflunomide tablets; and the patients in integrated Chinese and western medicine group received Huqianwan+methotrexate tablets and leflunomide tablets,with a treatment course of 12 weeks in all groups. The pain visual analog scale (VAS), swelling and tenderness scores of 28 joints (DAS28), average hands grip strength, morning stiffness time and liver-kidney Yin deficiency syndrome differentiation of traditional Chinese medicine (TCM) syndrome score were compared between groups before and after treatment. The changes of erythrocyte sedimentation rate (ESR), C reactive protein (CRP), immunoglobulin (Ig) G, tumor necrosis factor-alpha (TNF-α) and rheumatoid factor (RF) were detected in all groups after treatment. Clinical efficacy, and incidence of adverse reactions such as gastrointestinal response, liver injury, leukopenia, serum glutamate oxaloacetic aminotransferase (GOT) and platelet (PLT) level changes were compared between the groups, so as to investigate the efficiency and safety of the different medicines. Result: After 12 weeks of treatment, the total clinical effective rate was 79.0%, 80.7%, and 92.3% respectively in Chinese medicine group, western medicine group, and integrated Chinese and western medicine group; the integrated Chinese and western medicine group was significantly better than the Chinese medicine group and western medicine group (P<0.01), but there was no difference between the Chinese medicine group and western medicine group. Every treatment group can effectively improve liver and kidney Yin deficiency syndrome in RA patients (P<0.05), and the effect in integrated Chinese and western medicine group was superior to that in Chinese medicine group (P<0.05); the effect in Chinese medicine group was superior to that in western medicine group (P<0.05). The incidence of adverse reactions was Chinese medicine group (1.61%, 1/62)Conclusion: The efficacy in treating RA liver and kidney Yin deficiency syndrome shows no significant difference between modified Huqianwan and methotrexate tablets+leflunomide tablets. In the treatment of RA liver and kidney Yin deficiency syndrome, Huqianwan has fewer adverse reactions. Huqianwan combined with methotrexate tablets+leflunomide tablets is superior to that in methotrexate tablets+leflunomide tablets in treatment of RA liver-kidney Yin deficiency syndrome.

Objective To understand the water quality of self-supply wells in four provinces of northern China (Heilongjiang, Beijing, Inner Mongolia and Tibet), so as to provide a reference for supervision and management of self-supply wells. Methods Water were sampled from 233 self-supply wells in four northern provinces of China according to standard examination methods for drinking water (GB/T 5750-2006). In total, The samples were tested for 27 kinds of water quality parameters involving sensory properties, chemistry, bacteriology and toxicology, and then evaluated. Results The total unqualified rate of water quality in self-supply well water in four northern provinces of China was 52.36%. The water quality varied greatly among provinces. As for Heilongjiang, the main unqualified indicators of self-supply wells water involved turbidity, visible to the naked eye, manganese, arsenic and nitrate. In relation to Beijing, these referred to the nitrate and microorganism. In case of Inner Mongolia province, these included sulfate and fluoride. With reference to Tibet, these were zinc and chloride. Conclusions To ensure the safety of drinking water for residents, the management, disinfection and purifying measures of self-supply wells should be strengthened basing on their regional differences and water quality characteristics.

Objective To investigate the prognostic value of heart-type fatty acid-binding protein (H-FABP)in pediatric patients with severe sepsis and septic shock. Methods A prospective observational study was carried out in consecutive pediatric patients with severe sepsis and septic shock admitted between October 2016 and September 2017. Data of patient's demographics, clinical characteristics, blood biochemical markers including H-FABP, N-terminal B-type natriuretic peptide (NT-BNP), creatine kinase isoenzyme(CK-MB) and cardiac troponin I(cTnl), Lactate dehydrogenase (LDH) and Lactic acid (Lac), complications and survival status were collected and analyzed. The receiver operating characteristic (ROC) curve was mainly used to evaluate the power of a continuous variable for 28-day survival rate, and Kaplan-Meier analysis was used to compare 28-day survival curves in pediatric patients with severe sepsis and septic shock. Results A total of 78 cases with severe sepsis (n=33) and septic shock (n=45) were enrolled in this study. There were 64 survival cases and 14 non-survivor within 28 days after admission. The plasma levels of H-FABP, NT-BNP, LDH, CK-MB were significantly higher in non-survivor than those in survivor (49.10±65.14) vs. (5.06±4.29) ng/ml; (131.63±130.91) vs. (37.30±29.24) U/L; (2 403.88±415.97) vs.(2 971.57±279.49) U/L; (5 872.93±6 383.28)pg/ml vs. (1 656.86±2 715.73) pg/ml; respectively, all P＜0.05). The area under the receiver operating characteristic curve (AUC) of H-FABP was 0.858 (95％ confidence interval [CI]: 0.716-1.0; P=0.002), which was superior to CK-MB (AUC=0.841,95％CI: 0.696-0.986; P=0.003);LDH (AUC=0.818, 95％CI: 0.610-1.000; P =0.005) and NT-BNP (AUC=0.728, 95％CI: 0.535-0.921;P=0.045). A Kaplan-Meier curve showed a significantly lower survival rate in patients with H-FABP greater than 7.7 ng/mL than the patients with H-FABP less than 7.7 ng/mL. Conclusions H-FABP is an effective prognostic indicator in pediatric patients with severe sepsis and septic shock with superiority to traditional myocardial enzyme.

OBJECTIVE: To investigate the level and influencing factors of health-related quality of life in myasthenia gravis (MG) patients with myasthenia gravis quality of life-15 (MGQOL-15) Chinese version and to provide corresponding measures in one tertiary hospital of Sichuan Province. METHODS: We collected the general data (gender, age, body mass index BMI, marital status, educational level and employee status), clinical data [Osserman type, myasthenia gravis composite (MGC), other immunopathies, disease duration, frequency of outpatient visits per month, ratio of disease cost to income each month and frequency of symptoms during the past month] and the MGQOL-15 Chinese version from 168 myasthenia gravis patients in one tertiary hospital of Sichuan Province. RESULTS: The mean score of MGQOL-15 was 17.67±12.78. The score of the item "My occupational skills and job status have been negatively affected." was the highest, followed by "I have trouble using my eyes." and "I am frustrated by my MG." Single factor analysis showed that MG patients' QOL were different with different disease severity MGC (F=19.353, P<0.001), ratio of disease cost to income each month (F=5.831, P<0.001) and the frequency of symptoms during the past month (F=9.128,P<0.001). Multiple regression analysis showed that disease severity MGC (β=0.743,P<0.001), ration of disease cost to income each month (β=3.347,P<0.001) and the frequency of symptoms during the past month (β=2.216,P<0.003) were the main predictors of HRQOL in the MG patients. CONCLUSION Our study showed that the MGQOL-15 is helpful for clinicians to evaluate MG patients' QOL regularly, investigate the influencing factors and implement corresponding interventions the so as to improve the patients' quality of life. Disease severity MGC, ratio of disease cost to income each month and the frequency of symptoms during the past month were the main predictors of MG patients' QOL. Clinicians should pay more attention to MG patients' disease severity MGC and the frequency of symptoms during the past month.
