BACKGROUND: Death burden of stroke is severe with over one-third rural residents in China, but there is still a lack of specific national and high-quality reports on the urban-rural differences in stroke burden, especially for subtypes. We aimed to update the understanding of urban-rural differences in stroke deaths. METHODS: This is a descriptive observational study. Data from the national mortality surveillance system, which covers 323.8 million with 605 disease surveillance points (DSPs) across all 31 provinces, municipalities, and autonomous regions in China. All deaths from stroke as the underlying cause from 2015 to 2020 according to DSPs. Crude mortality rate and age-standardized mortality rate (ASMR) were estimated through DSPs. Average annual percentage change was used to explain the change in mortality rate. RESULTS: From 2015 to 2020, the majority of deaths from all stroke subtypes occurred in rural areas. There were significant differences between the changes of urban and rural ASMRs. On the whole, the changes in urban areas were evidently better, and the ASMR differences were basically expanding. Stroke ASMR in urban China decreased by 15.5%. The rural ASMR of ischemic stroke increased by 12.9%. The rural and urban ASMRs of intracerebral hemorrhage decreased by 24.9% and 27.4%, and those of subarachnoid hemorrhage decreased by 29.5% and 40.4%, respectively. The highest ASMRs of all stroke subtypes and the increasing trend of ischemic stroke ASMR make rural males the focus of stroke management. CONCLUSIONS The death burden of stroke varies greatly between urban and rural China. Rural residents face unique challenges.

Extracellular vesicles (EVs), nanoscale lipid bilayer vesicles actively secreted by organisms into the extracellular environment, are rich in specific bioactive substances, such as proteins, genetic materials and lipids. These vesicles are involved in intercellular interactions and can pass through the blood-brain barrier, and may thus potentially serve as important biological substances for treatment of neurological diseases. In this review, we summarize the biological origin of EVs and their therapeutic potential in neurological diseases, expound the possibility of EV-based treatment of neurological diseases using traditional Chinese medicine, and discuss the challenges and prospects of researches of EVs for the treating neurological diseases.

BACKGROUND:Grape seed extract has been shown to be effective in inhibiting the growth of androgen-dependent tumors(e.g.,breast cancer),and thus grape seed extract could theoretically inhibit epiphyseal closure induced by estrogen in late adolescence. OBJECTIVE:To screen the effects of grape seed extract on apoptosis of growth plate chondrocytes and epiphyseal closure in rats. METHODS:(1)In vitro experiment:Growth plate chondrocytes from rat large tibia and femur at logarithmic growth stage were obtained and cultured in groups:normal control group,model control group(adding 17β-estradiol to induce apoptosis),positive control group(adding letrozole and 17β-estradiol),grape seed extract group(adding 17β-estradiol and 10 μg/mL grape seed extract),Caspase-9 inhibitor group(adding 17β-estradiol and Caspase-9 inhibitor),Caspase-9 agonist group(adding 17β-estradiol and Caspase-9 agonist).Cell apoptosis was detected by flow cytometry after 48 hours of culture.(2)In vivo experiment:Thirty 3-month-old Sprague-Dawley rats were randomly divided into model control group,positive control group and low-,medium-and high-dose groups,with five rats in each group.All rats were injected subcutaneously with 17β-estradiol(3 times per week)to establish epiphyseal closure models,followed by intragastric administration of letrozole in positive control group and 0.05,0.2 and 0.8 g/kg grape seed extract in low-,medium-and high-dose groups,respectively,once a day until over 2/3 of the epiphyseal plate in the model control group was closed.The length of the tibia was then observed.Another 18 Sprague-Dawley rats were randomly divided into model control group,positive control group,and medium-dose group,with 6 rats in each group,treated as above for 1.5 continuous months.The expression of Caspase-9 protein in rat growth plate cartilage was detected by western blot. RESULTS AND CONCLUSION:(1)In vitro experiment:17β-estradiol could induce apoptosis in growth plate chondrocytes,and letrozole,grape seed extract,and caspase-9 inhibitors could all inhibit apoptosis in growth plate chondrocytes.(2)In vivo experiment:When more than 2/3 of the epiphyseal plate in the model control group was closed,the number of rats with epiphysis closure in the positive control and medium-dose groups was less than that in the model control group(P＜0.05),and the tibial length was longer than that in the model control group(P＜0.05),and the Caspase-9 protein expression in the tibial growth plate was lower than that in the model control group(P＜0.05).To conclude,the appropriate dose of grape seed extract can effectively inhibit the apoptosis of growth plate chondrocytes and delay epiphyseal closure,which has the potential to promote bone growth.

Objective To explore the efficacy of semaglutide in the treatment of type 2 diabetes mellitus(T2DM)com-bined with non-alcoholic fatty liver disease(NAFLD)and its effect on oxidative stress and inflammatory factors.Methods Totally 80 patients with T2DM accompanied by NAFLD admitted to the First Affiliated Hospital of Xinxiang Medical University from July 2021 to December 2022 were selected and randomly assigned to the observation group and the control group,with 40 patients in each group.Patients in the control group were treated with pioglitazone metformin and dapagliflozin,while patients in the observation group were treated with pioglitazone metformin,dapagliflozin,and semaglutide.The levels of glycated hemoglobin(HbA1c),fasting blood glucose(FBG),2-hour postprandial blood glucose(2hPG),body mass,body mass index(BMI),waist circumference,alanine aminotransferase(ALT),aspartate aminotransferase(AST),gamma-glutamyl transferase(GGT),controlled attenuation parameter(CAP),liver stiffness measurement(LSM),malondialdehyde(MDA),glutathione peroxidase(GSH-PX),lipid peroxide(LPO),tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),and interleukin-10(IL-10)before and after the treatment were compared.Results After 24 weeks of treatment,the overall response rate(ORR)in the observation group and control group was 92.5％(37/40)and 72.5％(29/40),respectively;and the ORR in the observation group was significantly higher than that in the control group(x2=5.541,P＜0.05).Before treatment,there was no statistically significant difference in the body mass,BMI,waist circumference,HbA1c,FBG,2hPG,ALT,AST,GGT,CAP,LSM,MDA,GSH-PX,LPO,TNF-α,IL-6,and IL-10 of patients between the 2 groups(P＞0.05);after 24 weeks of treatment,the body mass,BMI,waist circumference,HbA1c,FBG,2hPG,ALT,AST,GGT,CAP,LSM,MDA,LPO,TNF-α,IL-6,and IL-10 were significantly lower than before treatment,while GSH-PX was significantly higher than before treatment(P＜0.05);after 24 weeks of treatment,the body mass,BMI,waist circumference,HbA1c,FBG,2hPG,ALT,AST,GGT,CAP,LSM,MDA,LPO,TNF-α,IL-6,and IL-10 of patients in the observation group were significantly lower than those in the control group,and GSH-PX was significantly higher than that in the control group(P＜0.05).The incidence of adverse reactions in the observation group and the control group during the treatment period was 17.5％(7/40)and 12.5％(5/40),respectively;and the difference in the incidence of adverse reactions between the two groups was not statistically significant(P＞0.05).Conclusion Semaglutide significantly downregulates the levels of FBG,2hPG and HbA1c in patients with T2DM combined with NAFLD and reduces the body mass,waist circumference,liver enzyme level,hepatic fat content,hepatic fibrosis,oxidative stress,and inflammatory indicators.

The density and composition of lymphocytes infiltrating colon tumors serve as predictive factors for the clinical outcome of colon cancer.Our previous studies highlighted the potent anti-cancer properties of the principal compounds found in Garcinia yunnanensis(YTE-17),attributing these effects to the regu-lation of multiple signaling pathways.However,knowledge regarding the mechanism and effect of YTE-17 in the prevention of colorectal cancer is limited.In this study,we conducted isobaric tags for relative and absolute quantification(iTRAQ)analysis on intestinal epithelial cells(IECs)exposed YTE-17,both in vitro and in vivo,revealing a significant inhibition of the Wnt family member 5a(Wnt5a)/c-Jun N-terminal kinase(JNK)signaling pathway.Subsequently,we elucidated the influence and mechanism of YTE-17 on the tumor microenvironment(TME),specifically focusing on macrophage-mediated T helper 17(Th17)cell induction in a colitis-associated cancer(CAC)model with Wnt5a deletion.Additionally,we performed the single-cell RNA sequencing(scRNA-seq)on the colonic tissue from the Wnt5a-deleted CAC model to characterize the composition,lineage,and functional status of immune mesenchymal cells during different stages of colorectal cancer(CRC)progression.Remarkably,our findings demon-strate a significant reduction in M2 macrophage polarization and Th17 cell phenotype upon treatment with YTE-17,leading to the restoration of regulatory T(Treg)/Th17 cell balance in azoxymethane(AOM)/dextran sodium sulfate(DSS)model.Furthermore,we also confirmed that YTE-17 effectively inhibited the glycolysis of Th17 cells in both direct and indirect co-culture systems with M2 macrophages.Notably,our study shed light on potential mechanisms linking the non-canonical Wnt5a/JNK signaling pathway and well-established canonical β-catenin oncogenic pathway in vivo.Specifically,we proposed that Wnt5a/JNK signaling activity in IECs promotes the development of cancer stem cells with β-catenin activity within the TME,involving macrophages and T cells.In summary,our study undergoes the po-tential of YTE-17 as a preventive strategy against CRC development by addressing the imbalance with the immune microenvironment,thereby mitigating the risk of malignancies.

Objective To explore the effect of pregabalin on sleep of patients after video-assisted thoracic surgery(VATS).Methods 120 cases of patients undergoing VATS under general anesthesia were randomly divided into 75 mg pregabalin group(group A),150 mg pregabalin group(group B),and placebo group(group C),with 40 patients in each group.On the night of the operation,the morning and evening of the first day and the second day after the operation,the patients in the three groups were given one tablet of pregabalin(75 mg),one tablet of placebo with the same shape and smell,two tablets of pregabalin(150 mg)and two tablets of placebo with the same shape and smell respectively.Athens insomnia scale(AIS)was used to evaluate the incidence of postoperative sleep disturbance(PSD)on the night of operation,and the patients'sleep quality every night from one night before operation to the 2nd day after operation was assessed using the St.Mary's Hospital sleep questionaire(SMH).Pittsburgh sleep quality index(PSQI)was used to evaluate the patients'sleep quality one day before the operation,7 days after operation,and 1 month after the operation.The digital rating scale(NRS)was used to evaluate the patients'pain at the incision and the surgical side.The remedial analgesia,incidence of adverse events in the 72 h postoperative period,and patient satisfaction score were recorded.Results The incidence of PSD in group A,group B and group C was 45.0％,42.5％and 72.5％,respectively,the incidence of group A and group B was significantly lower than in group C(group A,B and C compared in pairs,P＜0.016 7).The SMH scores in group A and group B were significantly higher than in group C on the day of operation,the first day and the second day after operation(group A,B and C compared in pairs,P＜0.016 7).The incidence of NRS scores in groups A and B at the incision and postoperative remedial analgesia was significantly lower than in group C on postoperative day 1 and postoperative day 2(group A,B and C compared in pairs,P＜0.016 7).There was no statistically significant difference in the pain scores at the incision and shoulder among the three groups at the remaining time points.The postoperative patient satisfaction scores were significantly higher in group A and group B than in group C(P＜0.01).The incidence of dizziness in group B was significantly higher than in the other two groups(P＜0.016 7).Conclusion Oral administration of pregabalin(75 mg/150 mg)for 3 days after VATS can reduce the incidence of PSD and improve the quality of sleep that night,but oral administration of 150 mg pregabalin may increase the incidence of dizziness.

Objective:Based on latent profile analysis, the category characteristics of decisional dilemma of participating in thrombolysis decision-making agents of patients with acute myocardial infarction (AMI) are analyzed to reduce the decision-making difficulties of decision-making agents in AMI patients.Method:The 292 cases of decision-making agents of patients with AMI and treated by intravenous thrombolysis in emergency department of Xinjiang Uygur Autonomous Region People's Hospital were selected as respondents From January 2022 to June 2023.A cross-sectional survey was conducted using General Information Questionnaire, Perceived Social Support Scale, State-Trait Anxiety Inventory, Control Preference Scale, Wake Forest Physician Trust Scale and Decisional Conflict Scale.Selected Mplus 8.3 software to conduct potential profile analysis on the survey data.Results:The 281 valid questionnaires were ultimately collected, with 146 males and 135 females aged 35-72(55.61 ± 9.05) among 281 AMI patients; 135 acting decision-makers from the south, 146 females, aged 30-72(55.52 ± 6.74).The score of decisional dilemma of participating in thrombolysis of decision-making agents of patients with AMI was 45(41, 46). LPA analysis showed that decisional dilemma of participating in thrombolysis of decision-making agents can be divided into 4 latent profiles which were low-level decisional dilemma profile accounts for 16.01% (45/281), high-level decisional dilemma profile accounts for 16.38% (46/281), extra high-level decisional dilemma profile with social support restricting accounts for 35.23% (99/281) and extra high-level decisional dilemma profile with information restricting accounts for 32.28% (91/281). Multiple logistic regression analysis showed represented patients with AMI history, decision-making agent ′s age, gender, educational level, decision-making role, decision-making participation type were significant influencing factors of decisional dilemma of participating in thrombolysis of high-level decisional dilemma profile (all P<0.05);represented patients with AMI history, decision-making agent ′s age, gender, education level, decision-making role, assuming patient ′s treatment payment role, assuming patient ′s care role, perceived social support level, state anxiety level, decision-making participation type and trust doctors level were significant influencing factors of decisional dilemma of participating in thrombolysis of extra high-level decisional dilemma profile with social support restricting and extra high-level decisional dilemma profile with information restricting(all P<0.05). Conclusions:The level decisional dilemma of participating in thrombolysis of decision-making agents for intravenous thrombolysis treatment of AMI patients were high, and their decisional dilemma can be divided into low-level decisional dilemma profile, high-level decisional dilemma profile, extra high-level decisional dilemma profile with social support restricting and extra high-level decisional dilemma profile with information restricting.They should be purposively intervened based on their corresponding decisional dilemma profile.
