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.

ObjectiveTo analyze the trend of incidence, mortality rate and related life loss of colorectal cancer in Haishu District, Ningbo from 2017 to 2022, so as to provide a scientific basis for the prevention and treatment of colorectal cancer. MethodsThe incidence and death data of colorectal cancer among residents in Haishu District during 2017‒2022 were collected from the Ningbo Municipal Digital Disease Prevention and Control Platform. The incidence and mortality rate, the age-specific incidence and mortality rate, potential years of life lost (PYLL), potential years of life lost rate (PYLLR), and average years of life lost (AYLL) were calculated. The standardized rate was calculated based on the standardized population from the Sixth National Census in 2010, and the annual percentage change (APC) was calculated by Joinpoint Regression Program. ResultsA total of 2 595 cases of colorectal cancer were reported in Haishu District from 2017 to 2022, with a crude incidence rate of 68.23/100 000 and a standardized incidence rate of 39.72/100 000. There were no statistical differences in crude and standardized incidence rates(APC=2.288%, -0.160%,both P>0.05). In addition, a total of 898 colorectal cancer deaths were reported, with a crude mortality rate of 23.61/100 000 and a standardized mortality rate of 12.18/100 000, of which the crude mortality rate and standardized mortality rate of males showed an upward trend (APC=10.855%, 7.895%, both P<0.05). Furthermore, the crude incidence and mortality rate of colorectal cancer in males were higher than those in females (both P<0.05). The crude incidence and mortality rate of colorectal cancer in Haishu District showed an increasing trend by age (both P<0.05). PYLL caused by colorectal cancer was 7 818.52 person-years, and AYLL was 8.71 years, with a PYLLR of 2.06‰. ConclusionThe incidence and mortality rate of colorectal cancer in Haishu District are still at a high level. Colorectal cancer screening should be continued, relevant health knowledge should be facilitated and disseminated, awareness of early screening and diagnosis of colorectal cancer should be promoted, and ultimately improving the survival rate of the patients.

Objective To summarize the clinical efficacy of robotic-assisted left thoracic small-incision minimally invasive direct coronary artery bypass grafting(MIDCAB).Methods A retrospective analysis was conducted on the procedures and treatment outcomes of robotic-assisted MIDCAB in the Army Medical Center of PLA from October 2016 to June 2023.Baseline clinical information,MIDCAB-related data,perioperative conditions and data during follow-up were collected and analyzed.Results There were 23 patients subjected,including 21 males and 2 females,with a mean age of 58.17±7.49 years,and a body mass index(BMI)of 23.99±3.25 kg/m2.All of them experienced angina pectoris,and 1 had a history of myocardial infarction,1 had dilated cardiomyopathy,2 patients had chronic obstructive pulmonary disease(COPD),and 10 had a history of percutaneous coronary intervention(PCI).Robotic-assisted MIDCAB procedure was successfully completed.No internal mammary artery injury or transformation of the procedure occurred in these cases,and excellent bridging vessel flow was achieved after anastomosis of the internal mammary artery to left anterior descending branch.The incision length in the left chest was 8(8,8)cm,the operation time was 380(300,465)min,the intraoperative bleeding volume was 300(100,400)mL,the length of ICU stay was 3(2,3)d,the amount of thoracic drainage was 780(525,1 040)mL,and the postoperative length from surgery to discharge was 11.17±2.38 d.No mortality was observed during or within 30 d of hospitalization,and 1 patient was readmitted due to pericardial effusion within 30 d,and was discharged after symptomatic treatment including pericardiocentesis and drainage.No deaths,major adverse cardiovascular and cerebrovascular events(MACCE),or re-revascularization occurred in all patients during outpatient and telephone follow-up.Conclusion Robotic-assisted internal mammary artery dissection is a delicate and safe technique,and coronary artery bypass grafting in minimally invasive small-incision off-pump is effective,safe and feasible,with satisfactory short-and mid-term outcomes.The technique is suitable for minimally invasive coronary artery disease surgery and is worthy of popularization and application.

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:This study aims to investigate the therapeutic efficacy of staged endoscopic surgery for Shin-Ⅲ stage external auditory canal cholesteatoma. Methods:A retrospective analysis was conducted on the clinical data of 25 patients diagnosed with Shin-Ⅲ cholesteatoma of the external auditory canal, who were admitted to the Otology Center of the First People's Hospital of Foshan City from May 2020 to October 2024. All patients initially underwent endoscopic cholesteatoma removal. Based on the outcomes of the first-stage postoperative follow-up, patients were categorized into two groups: the repair type and the non-repair type. The non-repair type was further subdivided into simple and complex types. Of the total cases, 10 patients were of the repair type, with 9 requiring no further surgical intervention. The non-repair type comprised 15 patients, of which 8 were classified as simple type and underwent either tympanoplasty type Ⅰ or external auditory canal wall reconstruction during the second stage. The remaining 7 patients, identified as complex type, received open mastoidectomy or tympanotomy in the second stage, with or without ossicular chain reconstruction. Results:All patients were monitored for a minimum of six months postoperatively. The incidence of dry ear was observed in 22 patients, corresponding to a dry ear rate of 88.0%. Four cases experienced primary complications. Conclusion:Endoscopic phased operation for managing Shin-Ⅲ stage cholesteatoma of the external auditory canal can ensure that the surgical options match the severity of the lesions, reducing unnecessary surgical trauma and achieving good efficacy.

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.
