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 observe the effect of combination of partial body weight support and functional electrical stimulation on lower limb motor function for stroke patients. Methods From January,2023 to February,2024,60 stroke patients from Rehabilitation Hospital of Chancheng District People's Hospital in Foshan City were randomly divided into control group(n=30)and observation group(n=30).The control group received routine rehabilitation,while the observation group received a combination of ce-lestial orbit system and functional electrical stimulation in addition,for three weeks.They were assessed with Balance assessment and training system,Berg Balance Scale(BBS),Fugl-Meyer Assessment-Lower Extremities(FMA-LE)and Holden Functional Ambulation Category(FAC)before and after treatment. Results X-axis trajectory length,average speed of swaying,total wobble trajectory,Y-axis trajectory length,trajectory length per unit area,BBS score,FMA-LE score and FAC score improved in both groups after treatment(|t|＞4.809,P＜0.001);and all the indexes improved more in the observation group than in the control group(|t|＞2.268,P＜0.05),except X-axis trajectory length and average speed of swaying. Conclusion Supplement of the combination of partial body weight support and functional electrical stimulation is more effective on lower limb motor function,balance and walking for stroke patients.

Objective To explore the effectiveness of a nutritional intervention in rescuers who screened positive for depression. Methods A randomized controlled trial design was employed.From June to August,2022,4,460 rescuers were screened using the Self-Rating Depression Scale(SDS),and 1,615 positive cases were identified.Thirty-one volunteers were recruited and randomly divided into a nutritional intervention group and a control group.The intervention group received health education and nutritional intervention(a compound paste therapy primarily composed of red roses and Seville orange flowers),while the control group received psychological education.SDS scores were assessed before and after the intervention. Results There was a statistically significant decline in SDS scores in the nutritional intervention group after the intervention(P<0.05).Furthermore,the SDS scores of the intervention group were significantly lower than those of the control group,both before and after the intervention(P<0.05).No severe adverse reactions were observed during safety evaluation. Conclusion The nutritional intervention effectively reduced the depression scores in rescuers.Early nutritional intervention is recommended for rescuers who initially screen positive for depression.

Objective To explore the impact of clinical treatment decisions on the long-term survival of different molecular subtypes of locally advanced breast cancer(LABC),and to promote the development of more effective and individualized treatment regimens for LABC.Methods The cases of LABC diagnosed by pathology from 2010 to 2015 were searched in the database.Breast cancer-specific survival(BCSS)and overall survival(OS)were estimated by plotting Kaplan-Meier curves.The log rank test(Mantel-Cox)was used to analyze the difference between the groups,and the benefit population of LABC was determined after for age,TNM stage,grade,treatment methods.Results The 5-year OS and BCSS were 77.43％and 84.34％in breast-conserving,and 68.03％and 76.90％in mastectomy,respectively.The 5-year OS and BCSS of Luminal A LABC were 79.91％and 87.23％in breast-conserving,and 71.78％and 81.16％in mastectomy,respectively.The 5-year OS and BCSS of Luminal B LABC were 79.30％and 83.14％in breast-conserving,and were 70.37％and 76.92％in mastectomy,respectively.The 5-year OS and BCSS of triple-negative LABC were 60.77％and 68.13％in breast-conserving,and those of mastectomy were 47.13％and 55.94％,respectively.The 5-year OS and BCSS of HER2 positive were 75.42％,82.05％in breast-conserving,and were 67.05％and 75.01％in mastectomy,respectively;The 5-year OS and BCSS of triple-positive LABC were 86.12％and 91.63％in breast-conserving,and 74.54％and 82.56％in mastectomy,respectively.The 5-year OS and BCSS of well differentiated and N0 triple-positive LABC patients with chemotherapy were 88.24％and 76.91％,and those of patients without chmotherapy were 88.24％and 90.91％,respectively(BCSS:P=0.812;OS:P=0.311).Conclusion In the selective population,OS and BCSS of patients with LABC undergoing breast conserving surgery were significantly better than those of mastectomy.When OS and BCSS were compared for different molecular types and stages of LABC,breast-conserving surgery was still superior to total mastectomy.LABC could be considered for highly differentiated,N0 stage Triple positive without chemotherapy.

Objective To investigate the molecular typing,virulence,and drug resistance features of bacterial strains in a simultane-ous outbreak of paratyphoid fever A and B,and then provide evidence for the prevention and treatment of the simultaneous transmission of different types of paratyphoid fever.Methods The clinical data of 31 patients confirmed as paratyphoid fever in the Hospital of Xin-jiang Production and Construction Corps from September 2018 to November 2018 were retrospectively analyzed.The isolated strains were performed serotyping and drug sensitivity tests.The molecular typing and the detection of virulence and drug resistance genes were carried out by multiplex PCR,pulsed-field gel electrophoresis(PFGE),and multilocus sequence typing(MLST).Results A total of 32 strains of Salmonella paratyphi were isolated from 31 patients,with 19 strains classified as type A and 13 as type B.The intermedi-ate rates of all strains against ciprofloxacin were 100%.The molecular typing and serotyping results of 11 representative strains were consistent.The PFGE fingerprints of Salmonella paratyphi A and B were also consistent.The MLST of Salmonella paratyphi A was ST85,and that of Salmonella paratyphi B was ST86.All strains carried virulence island SPI1-SPI5 representative genes such as invA,sitC,sseL,sifA,mgtC,siiE,and sopB,and regulatory gene phoP.Salmonella paratyphi A also carried cytolethal distending toxin(CDT)genes with trimeric structure such as cdtB,pltA,and pltB.The virulence plasmid genes such as pefA,prot6E,and spvB were all negative.Conclusion The simultaneous transmission of Salmonella paratyphi A and B has the characteristics of high pathogenicity and poor sensitivity to ciprofloxacin,which should be highly concerned by clinical and laboratory personnel.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To analyze the prevalence and related factors of depression symptom among middle-aged and older adults belonging to Zhiguo ethnic minority groups,who experienced relative isolation prior to mod-emization and bypassed the transitional period associated with feudal monarchy in Yunnan Province.Methods:Using stratified cluster sampling,a total of 1 035 individuals from Zhiguo ethnic minority groups were investigated with the 9-item Patient Health Questionnaire(PHQ-9)to measure depression symptom scores(a total score≥5 was considered indicative of depression symptom).A self-administered questionnaire was utilized to investigate 24 cova-riates across five dimensions:sociodemographic,social-interpersonal network,mental health status,physical health status,and health behaviors.Results:Among the surveyed participants,231 individuals(22.32％)exhibited depres-sion symptoms.The logistic regression analysis showed that middle-aged and elderly people belonging to Zhiguo ethnic minority groups with occupations as laborers(OR=8.73),farmers(OR=7.34),and other professions(OR=7.13),those who reported feeling stressed or anxious in the last month(OR=5.43),those suffering from one(OR=2.81)or more chronic illnesses(OR=2.14),experiencing sleep problems(OR=3.74)/debilitating(OR=1.69)/mild-moderate pain(OR=2.23,4.37),and engaging in sedentary behavior(OR=2.27)were at higher risk for depressive symptoms.The risk of depressive symptoms was lower among middle-aged and elderly people be-longing to Zhiguo ethnic minority groups with higher social support scores(OR=0.96)and meaning in life scores(OR=0.96).Conclusion:The prevalence of depressive symptoms among middle-aged and elderly individuals of Zhiguo ethnic minorities is substantial,influenced by multiple factors.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.
