Objective:To investigate the expression pattern of 14 innate immunity related microRNAs ( miRNAs) in brucellosis patients.Methods:By using Real time PCR assay, expression levels of 14 miRNAs in serum samples from brucellosis patients and healthy volunteers were analyzed.Results: Of the 14 miRNAs tested, 13 showed decreased expression in brucellosis patients.And significant Ct differences over one were observed for nine of the miRNAs.In them,five miRNAs,including miR-122,miR-145a,miR-155,miR-301a and miR-146a levels significantly decreased in brucellosis patients (P<0.01).Conclusion:Decreased serum levels of miR-122,miR-145a,miR-155,miR-301a and miR-146a are confirmed and may serve as novel biomarkers for human brucellosis diagno-sis.

Objective:To investigate the effects of Liuweidihuang pill on the insulin levels in sera and pancreatic islets from spontaneous mouse models of human type 2 diabetes administrated with different doses .Methods:The 6-8 week-old KK-Ay mice were randomly divided into three groups including no drug control group ,low-dose group and high-dose group,in addition C57BL/6J mice were used as a genetic control group .All the animals were given with different dose Liuweidihuang pill solutions or sterile distilled water by intragastrical administration for fifteen weeks .The fasting blood glucose ,body mass and food consumption were measured weekly .The serum insulin levels were surveyed by ELISA .And the insulin levels in the pancreas islets were detected by immunofluorescence and immunohistochemistry .Results:Decreased fasting blood glucose ,controlled body mass and food consumption ,and lower levels of insulin in the sera and pancreas islets were confirmed from the KK-Ay mice administered with Liuweidihuang pill .Furthermore,the low dose program exhibits a stronger effect .Conclusion:Liuweidihuang pill has exhibited relatively therapeutic effects in the spontaneous type 2 diabetes mice including controls of hyperglycemia and body mass and relieving insulin resistance .In addition , the low-dose regimen showed even better treatment in controlling insulin levels in the sera and pancreas islets .

Objective To study the clinical efficacy of Bushen Huoxue decoction in the treatment of varicocele infertility and its influence on epididymis function and sperm vitality. Methods A total of 98 patients with varicocele infertility who were treated in our hospital from August 2016 to July 2018 were selected. The patients were randomly divided into control group of 49 cases and study group of 49 cases. The patients in the control group were treated with Maizhiling plus Wuzi Yanzong pill; the patients in the study group were treated with Bushen Huoxue decoction. After 12 weeks of treatment, the clinical efficacy of the patients was evaluated. The semen quality (including semen volume, sperm density, sperm motility, forward-moving sperm), sex hormones, and seminal plasma neutral α-glucosidase in the two groups were compared before and after treatment. After the end of treatment, the patients were followed up for 3 months to observe the pregnancy of the patients' spouse. Results After treatment, the total effective rate of the study group was87.76％, and the total effective rate of the control group was 69.39％. The semen quality, sex hormone and neutral α-glucosidase levels in the study group were better than those in the control group (P<0.05). Conclusion Bushen Huoxue decoction has a significant clinical effect in treating varicocele infertility. It can improve the semen quality, improve testosterone level and seminal plasma neutral α-glucosidase level, and improve the fertility of patients with varicocele.It is worthy of clinical promotion.

Background/Aims: Chronic hepatitis B (CHB) and fatty liver (FL) often co-exist, but natural history data of this dual condition (CHB-FL) are sparse. Via a systematic review, conventional meta-analysis (MA) and individual patient-level data MA (IPDMA), we compared liver-related outcomes and mortality between CHB-FL and CHB-no FL patients. Methods: We searched 4 databases from inception to December 2021 and pooled study-level estimates using a random- effects model for conventional MA. For IPDMA, we evaluated outcomes after balancing the two study groups with inverse probability treatment weighting (IPTW) on age, sex, cirrhosis, diabetes, ALT, HBeAg, HBV DNA, and antiviral treatment. Results: We screened 2,157 articles and included 19 eligible studies (17,955 patients: 11,908 CHB-no FL; 6,047 CHB-FL) in conventional MA, which found severe heterogeneity (I2=88–95%) and no significant differences in HCC, cirrhosis, mortality, or HBsAg seroclearance incidence (P=0.27–0.93). IPDMA included 13,262 patients: 8,625 CHB-no FL and 4,637 CHB-FL patients who differed in several characteristics. The IPTW cohort included 6,955 CHB-no FL and 3,346 CHB-FL well-matched patients. CHB-FL patients (vs. CHB-no FL) had significantly lower HCC, cirrhosis, mortality and higher HBsAg seroclearance incidence (all p≤0.002), with consistent results in subgroups. CHB-FL diagnosed by liver biopsy had a higher 10-year cumulative HCC incidence than CHB-FL diagnosed with non-invasive methods (63.6% vs. 4.3%, p<0.0001). Conclusions IPDMA data with well-matched CHB patient groups showed that FL (vs. no FL) was associated with significantly lower HCC, cirrhosis, and mortality risk and higher HBsAg seroclearance probability.

Objective To study the antifungal effect of demethylzelamaldehyde in vitro. Methods The minimum inhibitory concentrations （MIC） of demethylzeylasteral and fluconazole against 23 fungal strains were determined by micro liquid dilution method. The synergistic index （FICI） of the two drugs was determined using a checkerboard micro liquid dilution method. The synergistic effect of the combination of the two drugs was visually verified by paper diffusion experiments. Finally, the cytotoxicity of demethylzelamaldehyde was determined by CCK-8 method. Results Demethylzelamaldehyde showed a broad spectrum of antifungal activity when used alone, with MICs ranging from 4 g/L to 32 g/L. When combined with fluconazole, the effective concentration of fluconazole could be reduced from over 64 g/L to 0.25 g/L, with FICI values ranging from 0.129 to 0.254, indicating the synergistic effect of the two drugs. The CCK-8 results showed that demethylzeylasteral exhibited cytotoxicity only at concentrations four times higher than the MIC value. Conclusion Demethylzelamaldehyde exhibited good antifungal effect and synergistic effect with fluconazole, and its toxicity was low.
