AIM:We aimed to evaluate the effect of angiotensin(Ang)(1-7)on autophagy in MIN6 cells un-der high-palmitate(PA)and high-glucose culture conditions.METHODS:MIN6 cells were cultured under various con-ditions:Dulbecco's Modified Eagle Medium(control,CON),high glucose and high PA concentrations(GLT),Ang(1-7)plus high glucose and high PA concentrations[Ang(1-7)+GLT],A779 inhibitor plus Ang(1-7)plus high glucose and high PA concentrations[A779+Ang(1-7)+GLT],and 3-methyladenine(3-MA)plus Ang(1-7)plus high glucose and high PA concentrations[3-MA+Ang(1-7)+GLT].The expression of microtubule-associated protein 1 light chain 3(LC3)was assessed using immunofluorescence,and Western blot was used to measure the expression of the autophagy-related proteins LC3-Ⅱ/LC3-Ⅰ and P62.Apoptosis was quantified using flow cytometry.RESULTS:GLT cells had fewer cytoplas-mic organelles,more vacuolated cells,an altered autophagosome distribution,higher P62 expression(P＜0.05),and greater apoptosis(P＜0.05)than CON cells.Ang(1-7)+GLT cells showed greater autophagosome formation,much less cy-toplasmic vacuolization,a higher LC3-Ⅱ/LC3-Ⅰ ratio(P＜0.05),lower P62 expression(P＜0.05),and less apoptosis(P＜0.05)than CON cells.A779 negated the pro-autophagic effects of Ang(1-7)in the MIN6 cells.Furthermore,inhibition of autophagy with 3-MA resulted in significantly greater apoptosis in 3-MA+Ang(1-7)+GLT cells vs Ang(1-7)-treated cells.CONCLUSION:Ang(1-7)activates Mas receptors to promote autophagy in pancreatic β cells cultured under high-glucose and high-fat conditions,thereby mitigating apoptosis and cellular pathology.

Oropharyngeal squamous cell carcinoma(OPSCC)is a malignant tumor originating from the squamous epithelium of the oro-pharyngeal mucosa,accounting for more than 90％of oropharyngeal malignancies.In recent years,human papillomavirus(HPV)infec-tion has become one of the primary etiological factors of oropharyngeal squamous carcinoma.The incidence of HPV-associated oropharyn-geal squamous carcinoma has been rising annually,with a noticeable trend toward younger populations,posing a significant threat to hu-man health.Due to the distinct biological behavior and clinical characteristics of HPV-associated oropharyngeal squamous carcinoma com-pared to its non-HPV-related counterpart,the diagnostic and treatment strategies for oropharyngeal squamous carcinoma have undergone substantial changes.Prevention and screening for oropharyngeal squamous carcinoma are of critical importance.The diagnostic and treat-ment process involves multi-disciplinary collaboration,including oral and maxillofacial surgery,otolaryngology,head and neck surgery,oncology,radiology and pathology.Based on evidence from clinical practice,a comprehensive,integrated diagnostic and therapeutic ap-proach has been established,centered around the concept of"prevention,screening,diagnosis,treatment,and rehabilitation",covering the entire patient lifecycle and providing a valuable reference for clinical practice.

Oral squamous cell carcinoma(OSCC)is a malignant lesion originating from the oral mucosal squamous epithelium,account-ing for over 80％of oral and maxillofacial malignancies.Key etiological factors include tobacco,alcohol abuse,and betel quid chewing.In China,its incidence has shown an overall upward trend,posing a significant threat to public health.OSCC exhibits high local invasive-ness,making early diagnosis critical for improving prognosis.Its clinical management requires close multidisciplinary collaboration among oral and maxillofacial surgery,head and neck surgery,radiation oncology,medical oncology,reconstructive surgery,radiology,patholo-gy,and nutritional support teams.Given the increasing disease burden of OSCC and rapid development of multidisciplinary collaborative models,an expert panel has formulated this integrated management consensus based on evidence-based medicine and extensive deliber-ation.Centered on the'Prevention-Screening-Diagnosis-Treatment-Rehabilitation'framework,the consensus provides comprehensive guidance for the entire disease course of OSCC patients,aiming to standardize clinical practice.

In recent decades,the incidence of human papillomavirus(HPV)-associated oropharyngeal squamous cell carcinoma(OPSCC)has shown a marked increase.Significant changes have also occurred in the OPSCC diagnosis and treatment paradigm.Deter-mining HPV status prior to treatment is now essential,and radiotherapy/chemotherapy,immunotherapy,and minimally invasive surgical techniques have progressively emerged as key modalities for managing OPSCC.However,alongside these paradigm shifts,a comprehen-sive technical consensus guiding the entire diagnostic and therapeutic process for OPSCC patients is currently lacking.Given China's large population base and the rising incidence of OPSCC,an expert panel convened to develop a clinical technical consensus on OPSCC diagno-sis and management tailored to China's specific context.This consensus aims to further enhance and standardize understanding of OPSCC management techniques among relevant healthcare professionals.

Objective:To explore the anger emotional state,traits and expression characteristics in patients with schizophrenia with violent behavior in community.Methods:Twenty-five patients with schizopnrenia with a history of violent behavior among the community rehabilitation institutions were selected as the violent behavior group,and 74 patients with schizopnrenia without a history of violent behavior were selected as the nonviolent behavior group.The Brief Psychiatric Rating Scale(BPRS)was used to assess psychiatric symptoms,and the State-Trait An-ger Expression Inventory(STAXI)was used to assess anger characteristics.Results:Compared with the nonviolent behavior group,the violent behavior group had significantly higher scores in the trait of anger(patient dimension score,rational dimension score)and expression of anger(total score,restraint dimension score)[(28.0±23.8)vs.(19.6±13.3),(55.0±30.6)vs.(40.0±21.5),(34.2±11.6)vs.(27.3±10.7),(56.0±26.1)vs.(33.7±21.1),Ps＜0.05].Higher scores of rationality dimension of anger trait(OR=3.69,95％CI:1.43-7.98)and re-straint dimension of anger expression(OR=3.25,95％CI:1.39-7.47)were risk factors for violent behaviors.Conclusion:Compared with patients with schizopnrenia without violent behavior,patients with violent behavior history may show more lack of rationality,and poorer anger restraint.

Objective To investigate correlation between serum bilirubin levels of different subtypes and diabetic nephropathy(DN)in patients with type 2 diabetes mellitus(T2DM).Methods Clinical data of 494 patients with T2DM admitted to Suizhou Central Hospital Affiliated to Hubei Medical University from January 2019 to May 2023 were retrospectively analyzed,and they were divided into DN group(175 cases)and non-DN group(319 cases)according to whether they had DN.Correlation between levels of total bilirubin(TBil),direct bilirubin(DBil),indirect bilirubin(IBil)in serum and the occurrence of DN were analyzed.Results There were statistically significant differences on age,course of diabetes,hypertension,coronary heart disease,smoking,drinking,TBil,DBil,IBil,alanine aminotransferase(ALT),blood urea nitrogen(BUN),serum creatinine(SCr),uric acid(UA),total cholesterol(TC),triglyceride(TG),low density lipoprotein(LDL),high density lipoprotein(HDL),glycosylated hemoglobin(HbA1c),body mass index(BMI),systolic blood pressure,fasting plasma glucose(FPG)and estimated glomerular filtration rate between two groups.Age,course of diabetes,hypertension,coronary heart disease,TBil,DBil,IBil,ALT,BUN,SCr,UA,TC,TG,HDL,LDL,HbA1c,BMI and FPG were influencing factors of DN in female T2DM patients(P<0.05).Age,course of diabetes,hypertension,coronary heart disease,smoking,alcohol consumption,TBil,DBil,IBil,ALT,BUN,SCr,UA,TC,TG,HDL,LDL,HbA1c,BMI and FPG were influencing factors of DN in male T2DM patients(P<0.05).TBil,DBil and IBil were significantly correlated with development of DN in patients with T2DM(P<0.001).Risk of developing DN gradually decreased with increasied TBil(1-15 μmol/L),IBil(1-10 μmol/L)and DBil(1-4 μmol/L),but after TBil>15 μmol/L,IBil>10 μmol/L and DBil>4 μmol/L,increased in TBil,DBil and IBil levels no longer reduced risk of developing DN.Conclusion There is a non-linear correlation between levels of TBil,DBil,IBil and risk of DN in patients with T2DM.Within a certain range,TBil,DBil and IBil are independent protective factors for occurrence of DN,and reaching a certain level will no longer reduce risk of DN.There is no significant difference between serum bilirubin and risk of DN in different genders.
