OBJECTIVE: To observe the clinical efficacy of Xujiang Xie's bloodletting therapy combined with Qingyan Lige decoction on acute pharyngitis with lung-stomach heat accumulation. METHODS: A total of 88 patients with acute pharyngitis of lung-stomach heat accumulation were randomly divided into an observation group (44 cases, 4 cases dropped out) and a control group (44 cases, 4 cases dropped out). The control group was treated with oral Qingyan Lige decoction, 150 mL each time, twice a day for 6 continuous days. On the basis of the treatment in the control group, Xujiang Xie's bloodletting therapy was applied at bilateral Shaoshang (LU11), Shangyang (LI1), and Erjian (EX-HN6) in the observation group, 0.1-0.5 mL of bloodletting per site, once every other day for 3 times in total. The TCM symptom and sign score, complete blood count (white blood cell [WBC] count, neutrophilic granulocyte percentage [NE%]), inflammation indexes (serum levels of C-reactive protein[CRP], interleukin[IL]-1β, IL-6, tumor necrosis factor [TNF]-α) and immune indexes (？？, ？？, ？？) of the two groups were observed before treatment and after 6 days of treatment, and the clinical efficacy was evaluated. RESULTS: After 6 days of treatment, the sore throat scores, redness and swelling scores of pharyngeal mucosa and uvula, pharyngeal dry and burning scores, hyperemia scores of posterior pharyngeal lymphoid follicles, chill and fever scores, total scores of TCM symptom and sign, WBC count, NE%, CRP, IL-1β, IL-6, TNF-α and ？？ in both groups were decreased compared with those before treatment (P<0.05), the above indexes in the observation group were lower than those in the control group (P<0.01, P<0.05, P<0.001). After 6 days of treatment, the levels of ？？ and ？？ in both groups were increased compared with those before treatment (P<0.05), and the above indexes in the observation group were higher than those in the control group (P<0.001). The total effective rate of the observation group was 95.0% (38/40), which was higher than 90.0% (36/40) in the control group (P<0.001). CONCLUSION Xujiang Xie's bloodletting therapy combined with Qingyan Lige decoction could improve the symptoms in patients with acute pharyngitis of lung-stomach heat accumulation, inhibit inflammatory response and improve immune function.

Objective:To evaluate the effectiveness of virtual case teaching integrating standardized patients (SP) and objective structured clinical examination (OSCE) in enhancing students' clinical thinking and practical skills in experimental exercise therapy course.Methods:In April 2023, 52 students from the 2021 cohort and 54 students from the 2022 cohort of the Rehabilitation Therapy undergraduate program at Xinjiang Medical University were selected and divided into the experimental group and control group according to their classes. In the shoulder joint mobilization experimental class of the exercise therapy course, virtual SP teaching was performed in the experimental group of both cohorts. For the control group, student-led SP teaching was performed in the 2021 cohort, while the traditional "lecture + demonstration" method was used in the 2022 cohort. Upon completion of teaching, theoretical exams, case analysis, practical exams, and a teaching satisfaction survey were conducted on the students. Data were analyzed using the t-test and chi-square test in SPSS 25.0. Results:In both cohorts, the experimental group had similar theoretical exam scores ( P=0.207 and P=0.097, respectively) to the control group, but had higher practical exam scores ( P=0.013 and P=0.002, respectively) than the control group. In the case analysis exam, the experimental group scored higher than the control group in the 2022 cohort ( t=2.84, P=0.006) but similarly to the control group in the 2021 cohort ( t=1.53, P=0.132). All students believed that virtual SP teaching was most engaging. In terms of understanding complex concepts, increasing active participation, and fostering clinical thinking, the 2022 cohort was more satisfied with virtual SP teaching, whereas the 2021 cohort experienced no significant difference between virtual SP teaching and student-led SP teaching. In addition, the 2021 cohort found that student-led SP teaching was more helpful for improving doctor-patient communication skills. Conclusions:The application of virtual SP teaching in the experimental exercise therapy course effectively enhances students' practical skills and case analysis capabilities, contributing greatly to their overall clinical management thinking.

Non-alcoholic fatty liver disease (NAFLD) is a metabolic disease characterized by abnormal deposition of lipid in hepatocytes. If not intervened in time, NAFLD may develop into liver fibrosis or liver cancer, and ultimately threatening life. NAFLD has complicated etiology and pathogenesis, and there are no effective therapeutic means and specific drugs. Currently, insulin sensitizers, lipid-lowering agents and hepatoprotective agents are often used for clinical intervention, but these drugs have obvious side effects, and their effectiveness and safety need to be further confirmed. Adenosine monophosphate (AMP)-activated protein kinase (AMPK) plays a central role in maintaining energy homeostasis. Activated AMPK can enhance lipid degradation, alleviate insulin resistance (IR), suppress oxidative stress and inflammatory response, and regulate autophagy, thereby alleviating NAFLD. Natural herbal medicines have received extensive attention recently because of their regulatory effects on AMPK and low side effects. In this article, we reviewed the biologically active natural herbal medicines (such as natural herbal medicine formulas, extracts, polysaccharides, and monomers) that reported in recent years to treat NAFLD via regulating AMPK, which can serve as a foundation for subsequent development of candidate drugs for NAFLD.

Objective To investigate the therapeutic efficacy of artesunate(AS)on polycystic ovary syndrome(PCOS)in mice and explore the potential mechanism primarily.Methods Twenty-five female C57BL/6J mice were randomly divided into Control group,model group(PCOS group),low-and high-dose AS groups(AS15 and AS30 groups)and metformin group(Met group).In addition to the Control group,the mouse model of PCOS was established by subcutaneous injection of dehydroepiandrosterone(DHEA,60 mg/kg)following by a high-fat diet for 21 d.After modeling,AS of 15 and 30 mg/kg was intraperitoneally injected into the mice of the AS 15 and AS30 groups,respectively,and 200 mg/kg Met was given to those of the Met group by gavage,once per day,for 6 weeks.ELISA was used to detect serum testosterone(T),fasting insulin(FINS),luteinizing hormone(LH)and follicle-stimulating hormone(FSH),and the LH/FSH ratio was calculated.The levels of fasting blood glucose(FBG),triglyceride(TG)and total cholesterol(TC)were detected by automatic biochemical analyzer,and the homeostasis model assessment of insulin resistance(HOMA-IR)was calculated.The estrous cycle was observed,and HE staining was performed for pathological changes in the ovary and uterus.Immunofluorescence assay was employed to measure the expression of p-eIF2α,ATF4 and CHOP in the ovarian tissue.After steroidogenic human granulosa-like tumor cell line KGN were exposed to 100 μmol/L DHEA to simulate the hyperandrogen environment of PCOS,and then treated with 5 and 10 μg/mL AS for 24 h,the protein levels of endoplasmic reticulum stress signaling pathway was detected by Western blotting.Results Compared with the Control group,the PCOS mice had disturbed estrous cycle,polycystic changes in the ovaries,and significantly increased serum T level and LH/FSH ratio(P＜0.05),and obviously elevated HOMA-IR,TC and TG levels in terms of metabolism(P＜0.01).The expression levels of p-eIF2α,ATF4 and CHOP were notably up-regulated in the ovarian granulosa cells of PCOS mice and KGN cells after DHEA exposure(P＜0.05).Additionally,AS treatment attenuated the pathological changes of ovary and uterine expression,decreased the serum T level and the LH/FSH ratio(P＜0.05),and reduced HOMA-IR,TC and TG levels(P＜0.05)when compared with the PCOS mice.Moreover,the expression levels of p-eIF2α,ATF4 and CHOP were significantly down-regulated after AS treatment in both ovarian granulosa cells of PCOS mice and KGN cells(P＜0.05).Conclusion AS significantly improves glycolipid metabolic disorder and reproductive dysfunction in PCOS mice,which may be associated with its suppressing endoplasmic reticulum stress by inhibiting the PERK/eIF2α/ATF4/CHOP pathway.

Objective To investigate the role of p300 in lipid metabolism disorders.Methods Bioinformatics analysis was performed to analyze the expression patterns of p300 in lipid metabolism disorder-related diseases and its correlation with SREBP-1c and downstream lipid metabolic enzymes.Immunofluorescence assay was used to detect the expression of p300 in the liver tissues of the patients with varying disease severity of non-alcoholic fatty liver disease(NAFLD).A mouse model of lipid metabolism disorder was established in male C57BL/6J mice by feeding high-fat diet(HFD)for 12 weeks.Western blotting was employed to assess p300 expression level in the liver tissues of HFD-fed mice.A cell model of lipid metabolism disorder was established in HepG2/AML-12 cells induced with free fatty acid(FFA).The effects of siRNA-mediated knockdown of p300 was observed to measure the levels of intracellular total cholesterol(TC)and triglyceride(TG),lipid deposition,and production of reactive oxygen species(ROS).Results Clinically,p300 was highly expressed in lipid metabolism disorders,and its level was positively correlated with NAFLD severity(P<0.05).Gene Set Enrichment Analysis(GSEA)revealed that p300 expression was significantly associated with fatty acid metabolism,cholesterol homeostasis,lipogenesis,PPAR signaling pathway,and peroxisome pathway.In vivo,p300 was significantly up-regulated in the livers of HFD-fed mice(P<0.01).In vitro,FFA stimulation markedly increased p300 expression in both HepG2 and AML-12 cells(P<0.01),whereas p300 knockdown significantly reduced intracellular TG and TC levels(P<0.01),attenuated lipid droplet accumulation,and reversed FFA-induced ROS elevation(P<0.01).Furthermore,p300 expression was positively correlated with the expression of SREBP-1c and its downstream key lipid synthesis enzymes.Conclusion p300 may promote hepatic lipid accumulation by acetylating and activating SREBP-1c and regulating downstream lipid metabolic enzymes,thereby affecting lipid synthesis and oxidative stress.These findings suggest that p300 may be a potential therapeutic target for lipid metabolism disorder-related diseases.
