Minor stroke is a common subtype of acute ischemic stroke， primarily defined by a National Institutes of Health Stroke Scale score ≤3 or ≤5. Despite mild clinical symptoms， it carries a risk of early deterioration， and its intravenous thrombolysis strategy has long been controversial. This article systematically summarizes the results of key randomized controlled trials in recent years， which found that although non-inferiority has been confirmed among thrombolytic agents such as alteplase， tenecteplase， and prourokinase， none of these have shown superior functional improvement in the treatment of minor stroke compared with dual antiplatelet therapy or aspirin monotherapy， and they carry safety risks such as symptomatic intracranial hemorrhage. Subgroup analyses suggested potential benefits for patients with a National Institutes of Health Stroke Scale score>3， disabling symptoms， or the large artery atherosclerosis subtype， but the evidence is inconsistent. The limited net benefit of thrombolysis is primarily attributed to heterogeneous definitions， a generally favorable natural prognosis， and the offsetting effect of bleeding risks. Future studies should focus on unifying definitions， leveraging multimodal imaging for precise patient selection， optimizing drug regimens， and ultimately achieving precise stratification and individualized thrombolytic interventions for minor stroke.

BackgroundAs a high prevalence disorder， schizophrenia has caused significant burden to family and society due to the impairment of occupational and social function. Currently， the dominant vocational training model in China follows a paternalistic， clinician-led decision-making approach. Although it improves patients' social function to some extent， it undermines their autonomy and treatment adherence. Therefore， it is urgently necessary to explore a new intervention method to enhance treatment compliance and social function in patients. ObjectiveTo explore the impact of shared decision-making oriented vocational training on social function in hospitalized schizophrenia patients， so as to provide references for rehabilitation interventions. MethodsA total of 68 patients diagnosed with schizophrenia according to the International Classification of Diseases， tenth edition （ICD-10） criteria were consecutively enrolled from January to June 2024 at The Third People's Hospital of Wenjiang Distric， Chengdu. Participants were randomly allocated into the research group （n=34） and the control group （n=34） using a random number table method. Both groups received routine rehabilitation training， while the research group received shared decision-making oriented vocational training for 12 weeks， 2 times a week for 2 hours each time. Before and at the 4^th and 12^th week of intervention， two groups were evaluated by General Self-Efficacy Scale （GSES）， Stigma Scale for Mental Illness （SSMI）， Scale of Social function of Psychosis Inpatients （SSFPI） and Inpatient Psychiatric Rehabilitation Outcome Scale （IPROS）. ResultsA total of 63 participants completed the study， with 30 cases in the research group and 33 cases in the control group. Repeated measures ANOVA revealed statistically significant time effects and interaction effects in both groups for GSES， SSMI， SSFPI and IPROS scores （F=20.451， 16.022； 26.193， 12.944； 23.957， 5.023； 11.776， 3.985， P<0.05 or 0.01）， while no significant group effects were observed （F=0.188， 0.742， 1.878， 0.474， P>0.05）. At the 12^th week of intervention， there were statistically significant differences in GSES， SSMI， SSFPI and IPROS scores between the two groups. ConclusionShared decision-making oriented vocational training may help to improve social function in patients with schizophrenia. ［Funded by 2023 Chengdu Medical Research Project （number， 2023468）］

Objective To compare the application value of direct arteriovenous fistula(AVF),after ultrasound-guided percutaneous transluminal angioplasty(PTA)dilation of radial artery AVF formation and reverse"J"arteriovenous graft(AVG)in hemodialysis patients with small diameter vessels.Methods Totally 96 end-stage renal disease patients with distal radial artery＜1.5 mm and cephalic vein≥2.0 mm who planning to receive hemodialysis were retrospectively enrolled.The patients were divided into AVF group(n=30),PTA+AVF group(n=34)and AVG group(n=32)according to fistulization methods.The technical success rate,clinical success rate,primary patency rate and secondary patency rate were compared among groups.Results The technical success rate of AVF group,PTA+AVF group and AVG group was 80.00%,94.12%and 100%,respectively,and the clinical success rate was 30.00%,82.35%and 93.75%,respectively,with significant differences among 3 groups(both P＜0.05).The primary patency rate 1,3,6,9 and 12 months after fistulization in AVF group was 80.00%,30.00%,27.59%,27.59%and 24.14%,respectively,in PTA+AVF group was 94.12%,82.35%,78.79%,68.75%and 62.50%,respectively,while in AVG group was 100%,93.33%,83.33%,76.67%and 66.67%,respectively,all being significant different among 3 groups(all P＜0.05).The secondary patency rate 1,3,6,9 and 12 months after fistulization in AVF group was 83.33%,75.00%,75.00%,70.83%and 58.33%,respectively,in PTA+AVF group was 93.33%,93.33%,83.33%,83.33%and 80.00%,respectively,while in AVG group was 100%,100%,93.33%,90.00%and 80.00%,respectively,also being significant different among 3 groups(all P＜0.05).Conclusion Compared with direct and after ultrasound-guided PTA dilation of radial artery AVF formation,AVG formation was more valuable for hemodialysis patients with small diameter vessels.

Objective To investigate the impact and underlying mechanism of curcumin(Cur)on the aberrant proliferation and migration of VSMC.Methods VSMC was treated with Ang Ⅱ to establish a cell proliferation model.The experiment included blank control group,model group,and low-,medium-and high-dose Cur treatment groups(1.5,3.0 and 4.5 pmol/L,n=11).To explore the effect of Cur on the AMPK/mTOR signaling pathway,VSMC was also assigned into blank control,Ang Ⅱ(10-6 mol/L),Cur(3.0 μmol/L)and Ang Ⅱ+Cur groups(n=3).Western blotting was employed to detect the expression of VSMC differentiation markers(α-SMA),dedif-ferentiation marker(OPN),autophagy-related proteins(P62 and Beclin-1),and proteins involved in the AMPK/mTOR pathway(AMPK,p-AMPK,mTOR,p-mTOR,p70S6K,p-p70S6K).Results Exposure to Ang Ⅱ enhanced the proliferation and migration of VSMC when compared with the blank control group(155％vs 100％,66％vs 48％,P＜0.05).When compared with the model group,the proliferative rate was significantly lower in the medium-and high-dose Cur groups,and the migratory rate was obviously decreased in the three Cur groups(P＜0.05).The α-SMA expression was increased in the medium-and high-dose Cur groups,and that of OPN was decreased in the three Cur groups when compared with the model group(P＜0.05).Enhanced Be-clin-1 and p-AMPK/AMPK and down-regulated P62,p-mTOR/mTOR,and p-p70S6K/p70S6K were observed in the Ang Ⅱ and Cur groups than the blank control group(P＜0.05).The Cur Ang Ⅱ and Cur+AngⅡ groups had notably higher Beclin-1 and p-AMPK/AMPK but lower P62,p-mTOR/mTOR,and p-p70S6K/p70S6K than the Ang Ⅱ group(P＜0.05).Conclusion Cur in-hibits the proliferation and migration of VSMC induced by Ang Ⅱ,potentially through its activa-ting the AMPK/mTOR signaling pathway and enhancing autophagy in VSMC.

Objective To investigate the level 4 surgical safety management in tertiary public hospitals in Sichuan Province.Methods A combination of questionnaires and qualitative interviews was used to investigate the basic situation of four-level surgery performed,the volume of surgery,and the management of surgery in 34 tertiary public hospitals in Sichuan Province.Results Among the 34 tertiary public hospitals surveyed,the percentage of patients discharged with level Ⅳ surgery in 2023 was 18.96％,which was lower than the level of the percentage of patients discharged with level Ⅳ surgery did not establish a leading group for level Ⅳ surgery (17.65％),a system for preoperative multidisciplinary discussion of level Ⅳ surgery(14.71％),and a system for preoperative multidisciplinary discussion of level Ⅳ surgery with various department-related expert pool(41.18％),multidisciplinary joint examination room(23.53％),and the monitoring and evaluation mechanism for the completion of preoperative multidisciplinary discussion for level 4 surgery(20.59％).Conclusion The volume of level Ⅳ surgeries in tertiary public hospitals in Sichuan Province needs to continue to be improved,and the establishment of a standardized management system for level Ⅳ surgeries is imperative.

Public hospitals have introduced third-party payment methods to improve patients'medical treatment experience,however large public hospitals face challenges in financial reconciliation due to the complexity of income types,multiple accounting units,and delayed cross-hospital reconciliation.Based on the practical experience of the First Affiliated Hospital of Zhengzhou University in financial management,it analyzes the current situation of third-party payment in hospitals and identifies key problems in financial reconciliation,such as increased risk of re-funds,prominent single-sided accounting issues,and low efficiency of manual reconciliation.It proposes strategies for optimizing the hierarchical structure of the reconciliation post,updating accounting subjects rationally,and im-proving the intelligence of the reconciliation system,to provide reference for financial reconciliation work in large pub-lic hospitals under third-party payment methods and improve the operational efficiency of public hospitals.

Objective:To investigate the computed tomography (CT) imaging features of patients with chronic hydrocephalus after intracerebral hemorrhage surgery and the difference between endoscopic third ventriculostomy (ETV) and ventricular peritoneal shunt (VPS).Methods:A total of 158 patients with intracerebral hemorrhage who received surgical treatment in the Department of Neurosurgery of the People′s Hospital of Jinan from January 2021 to June 2023 were retrospectively selected as the study objects, including 78 patients with chronic hydrocephalus after surgery as the hydrocephalus group, and 80 patients with no hydrocephalus after surgery as the non-hydrocephalus group, and the CT imaging data of the patients were statistically analyzed. Hydrocephalus group was divided into ETV group (42 cases) and VPS group (36 cases) according to different treatment methods. The efficacy and quality of life of the two groups were compared, and the incidence of complications in the two groups were counted.Results:There was no significant difference between hydrocephalus group and non-hydrocephalus group in the site of cerebral hemorrhage, hematoma morphology and the proportion of patients with mixed signs, lobular signs and black hole signs (all P>0.05). The proportion of patients with ventricular dilation and hematoma enlargement in hydrocephalus group was significantly higher than that in non-hydrocephalus group (all P<0.05). The National Institute of Health Stroke Scale (NIHSS) scores of hydrocephalus patients in the two groups were measured continuously at different time points, and there was no significant difference in NIHSS scores between the ETV group and the VPS group before treatment, at 2 weeks and 4 weeks of treatment (all P>0.05). There was no significant difference between the ETV group and the VPS group ( P>0.05). The recurrence rate of the ETV group was lower than that of the VPS group ( P<0.05). The quality of life scores of patients in ETV group were higher than those in the VPS group at 3 months and 6 months after surgery ( P<0.05). Conclusions:CT examination of patients with chronic hydrocephalus after intracerebral hemorrhage will show obvious characteristics of hematoma enlargement and ventricle enlargement. The efficacy of ETV and VPS in the treatment of chronic hydrocephalus after intracerebral hemorrhage surgery is similar, but the former has a lower recurrence rate and a higher postoperative quality of life.

The Diagnosis-Intervention Packet(DIP)payment exerts notable effects on hospitals' economic operations.As centralized hubs of high-quality medical resources,tertiary hospitals face a functional mismatch with the provision of services for primary care diseases.By analyzing the admission and payment practices for primary care diseases in sample hospitals in Henan Province,it identifies key challenges,including inadequate alignment between healthcare payment reform policies and management systems,weak foundational capabilities in hospital health insurance informatization,and insufficient awareness of health insurance policies among medical staff.It is recommended that hospitals should strengthen communication and coordination with health insurance administration agencies to foster positive interactions between healthcare providers and insurers;continuously advance in-house health insurance informatization and enhance data governance capabilities;improve strategic awareness and innovate value-based health insurance management models.

Objective To investigate the expression of microRNA-508-3p(miR-508-3p)in epithelial ovarian cancer(EOC)tissue,its impact on the migration and invasion of ovarian cancer cells,and its regulatory relationship with zinc-finger E-box-binding homeobox 1(ZEB1).Methods The surgical resection of EOC cancer tissues and paired adjacent normal tissues were collected.SKOV3 cells were divided into the NC mimic group(transfected with NC mimic),miR-508-3p mimic group(transfected with miR-508-3p mimic),si-NC group(transfected with si-NC),si-ZEB1 group(transfected with si-ZEB1)and co-transfection group(co-transfected with si-ZEB1 and miR-508-3p mimic).The mRNA expression levels of miR-508-3p and ZEB1 in EOC cancer tissues,adjacent normal tissues and five groups of cells were measured by real-time quantitative polymerase chain reaction.The Transwell assay was used to detect the cell migration and invasion abilities.Results The relative expression levels of miR-508-3p in EOC tissues and adjacent normal tissues were 0.77±0.36 and 1.07±0.40,the relative expression levels of ZEB1 mRNA in EOC tissues and adjacent normal tissues were 2.10±1.21 and 1.29±0.95,and the differences were statistically significant(all P＜0.01).The migration cell number of the NC mimic,miR-508-3p mimic,si-NC,si-ZEB1 and co-transfection groups was 633.00±32.49,319.20±19.89,650.40±25.85,375.00±17.25 and 129.40±17.10;the invasion cell number was 527.20±25.01,288.60±16.68,520.00±25.83,293.40±18.37 and 76.60±8.76;the relative expression levels of miR-508-3p were 1.05±0.37,3.94±1.21,1.01±0.21,1.26±0.34 and 3.40±0.41;the relative expression levels of ZEB1 mRNA were 1.00±0.04,0.58±0.05,1.00±0.08,0.54±0.07 and 0.29±0.03,respectively.The above indicators showed statistically significant differences between the miR-508-3p mimic group and the NC mimic group,between the si-NC group and the co-transfection group(P＜0.01,P＜0.05).Conclusion MiR-508-3p is lowly expressed in EOC cancer tissue,and it may inhibit the migration and invasion of ovarian cancer cells by targeting ZEB1 expression.

Porcine reproductive and respiratory syndrome virus(PRRSV)mainly causes sow abor-tion,stillbirth,mummified fetus and respiratory symptoms in piglets.Since first reported in China in 1996,the virus complexity has increased significantly in more than 20 years of genetic evolution,bringing huge economic losses to the pig industry.In recent years,with the emergence of various PRRSV recombinant virus strains,preventing and controlling this epidemic became increasingly difficult.The purpose of this article is to comprehensively review the genome structure and func-tion of PRRSV,RNA virus recombination mechanism,main types of recombination,and the epi-demic status and recombination for the dominant epidemic PRRSV strains,in order to provide clues for in-depth research on gene recombination of PRRSV,thus providing the theoretical sup-port for formulating scientific prevention and control strategies.
