In the context of non-alcoholic fatty liver disease (NAFLD), characterized by dysregulated lipid metabolism in hepatocytes, the quest for safe and effective therapeutics targeting lipid metabolism has gained paramount importance. Sanhuang Xiexin Tang (SXT) and Baihu Tang (BHT) have emerged as prominent candidates for treating metabolic disorders. SXT combined with BHT plus Cangzhu (SBC) has been used clinically for Weihuochisheng obese patients. This retrospective analysis focused on assessing the anti-obesity effects of SBC in Weihuochisheng obese patients. We observed significant reductions in body weight and hepatic lipid content among obese patients following SBC treatment. To gain further insights, we investigated the effects and underlying mechanisms of SBC in HFD-fed mice. The results demonstrated that SBC treatment mitigated body weight gain and hepatic lipid accumulation in HFD-fed mice. Pharmacological network analysis suggested that SBC may affect lipid metabolism, mitochondria, inflammation, and apoptosis-a hypothesis supported by the hepatic transcriptomic analysis in HFD-fed mice treated with SBC. Notably, SBC treatment was associated with enhanced hepatic mitochondrial biogenesis and the inhibition of the c-Jun N-terminal kinase (JNK)/nuclear factor-kappa B (NF-κB) and extracellular signal-regulated kinase (ERK)/NF-κB pathways. In conclusion, SBC treatment alleviates NAFLD in both obese patients and mouse models by improving lipid metabolism, potentially through enhancing mitochondrial biogenesis. These effects, in turn, ameliorate inflammation in hepatocytes.

【Objective】 To establish an experimental method for detecting phagocytosis of sensitized red blood cells in vitro by flow cytometry. 【Methods】 Mononuclear cells were isolated from the peripheral blood of blood donors and cultured in a cell incubator for 1 hour, and then adherent monocytes were isolated and obtained. Di^b-positive red blood cells (RBCs) were labeled with PKH26 and then sensitized with IgG anti-Di^b. The sensitized RBCs were added to monocytes for in vitro phagocytosis assay. Monocytes were labeled with FITC anti-human CD14, then phagocytosis was measured by flow cytometry, and the phagocytic efficiency was calculated. The method was used to detect the phagocytic efficiency of monocytes on human IgG anti-D sensitized RBCs with different titers. 【Results】 The phagocytic efficiency of monocytes was averaged at 5% (1.2%~7.6%, SD 3.30) versus 81% (71.4%~92.7%, SD 8.65) in the negative versus positive control group, respectively. Phagocytic activity of monocytes mediated by anti-D was correlated with the antibody titer. The phagocytosis efficiency was within 10% when the antibody titer was lower than 32 and increased sharply when the titer was between 32 to 128, it entered a plateau and stabilized at 80% at the titer above 256. 【Conclusion】 A detection platform for detecting phagocytosis-sensitized RBCs in vitro by flow cytometry has been successfully established. It can be used to assess the clinical significance of red blood cell allotype or autologous IgG antibodies.

Objective: To investigate the prevalence of bullying and its association with quality of life in Shenzhen middle school students’ and to provide scientific basis for intervention measures. Methods: The study was a cross-sectional study with stratified cluster sampling. The short version of World Health Organization Quality of Life (WHOQOL-BREF), Center for Epidemiological Studies Depression Scale (CES-D) and Self-completed questionnaires, including demographic characteristics and bullying, were utilized to examine the study objectives. 2 103 school students from Shenzhen were selected to take part in the study during July-October of 2017. Multiple liner regression analysis was used to analyze the association between bullying and quality of life. Results: 418 middle school students (19.9%) suffered bully in the past year. 326 students (15.5%) suffered traditional bullying and 182 students (8.7%) suffered cyberbullying in the past year. Male students, junior middle school students and those with bad grades as well as bad relationship with family and classmates were more likely to suffer bullying(χ2=8.89, 41.56, 14.83, 23.42, 32.26, 46.75, P<0.05). The prevalence of depression in students with bullying experience was significantly higher than those without bullying. Students with bullying experience reported significantly lower scores than those without bullying experience in physical domain, psychological domain, social relationship domain and environment domain, and the differences were of statistical significance(t=-7.54, -7.08, -6.88, -6.02, P<0.01). Conclusion The prevalence of bullying in middle school students was high. It was negatively associated with students’ quality of life. The findings underscore the importance of developing psychological interventions for students with bullying.

Objective To investigate high risk human papillomavirus(HR-HPV)prevalence among married women in Beijing and to study the high risk flactors.nethods During March 2007 to September 2008.a total of 6185 married women sampled from 137 communities in 12 districts were screened bv HR-HPV DNA test and cytogical test.The interview was carried out with unified questionnaires.The databage was set up and twice entered in EpiDam 3.0.After checked up,the data were analyzed in SPSS 15.0.Results (1) The HR-HPV infection rate was 9.89%.The HR-HPV infection rate of the city zone,the suburb and the exurb were 9.34%,10.51% and 9.51% (P>0.05).The HR-HPV infection rate of the native and the oudander were 9.53%,11.30% (P<0.05).(2) The age distribution of HR-HPV infection was that the rate was around 10% among 25 to 44 age groups,which was the highest(11.21%) in 30 to 34 age group;then the rate was descended as the age raising,the rate of 50 to 54 age group was the lowest(7.78%).(3) Multiple logistic regression showed that the related risk factors of HR-HPV infection mainly included 1000 RMB and above of family income per person per month.possessing more than 1 sexual partner of her husband,outlander and hish levels of education.(4) The prevalence of cervical intraepithelial neoplasia(CIN)in HR-HPV positive group wag significantly higher than that in HR-HPV negative group(29.76% vs 3.32%,P<0.01).Conclusions(1)The HR-HPV infection rate among aged 25 to 54 years was 9.9% and there was no significant difference in area distribution.(2)The hish risk population which should strengthen screening was the married bearing-age women with high level of family income,outlander,high levels of education and her husband possessing more than 1 sexual partner.(3)HR-HPV infection is the main risk factor for CIN and cervical cancer.while does not provide a causal relationship with them.The high risk population should be checked regularly to understand the development of HR-HPV infection and CIN incidence.
