Objective To explore the application effect of the Mini-CEX evaluation model based on the OBE concept in the clinical Practice teaching of neurology.Methods We Selected 100 students who will Practice in the Department of Neurology from 2022 to 2023 as the research objects,and divided them into the experimental group(n=50)and the control group(n=50).Under the guidance of the OBE concept,the experimental group was guided by learning outcomes,refined the teaching objectives,and applied the Mini-CEX evaluation mode for evaluation and feedback.In contrast,the control group adopted the traditional teaching mode.Combined with the observation data,we analyzed and compared the data of various indicators of the two groups of students at the beginning and end of the internship.Results At the end of the internship,the scores of clinical consultation,Physical examination,humanistic medicine,clinical diagnosis,health consultation,organizational effect,and overall evaluation of the experimental group were significantly improved and were higher than those of the control group.After the Practice,in terms of skill test scores,the experimental group scored higher than the control group,the difference was statistically significant(P<0.05),and the experimental group also scored higher in satisfaction evaluation than the control group.Conclusion The Mini-CEX evaluation teaching model based on the concept of OBE is applied to the clinical practice teaching of the neurology department,which can enhance the training effect of students'clinical practice skills.

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: This study aimed to analyze the temporal trends and characteristics associated with waist circumference (WC) among elderly Chinese people. Methods: We used data from 3,096 adults ≥ 65 years who participated in the China Health and Nutrition Survey (CHNS), an ongoing cohort study, between 1993 and 2015. We used longitudinal quantile regression models to explore the temporal trends and characteristics associated with WC. Results: WC increased gradually among the elderly Chinese population during the survey. The WC curves shifted to the right with wider distributions and lower peaks in men and women. All WC percentile curves shifted upward with similar growth rates in the 25th, 50th, and 75th percentiles. The WC means increased from 78 cm to 86 cm during the 22 years of our study. WC significantly increased with age and body mass index and decreased with physical activity (PA). These associations were stronger in the higher percentiles than in the lower percentiles. Conclusions WC is rising among Chinese adults ≥ 65 years. Factors affecting WC in elderly people may have different effects on different percentiles of the WC distribution, and PA was the most important protective factor in the higher percentiles of the WC distribution. Thus, different interventional strategies are needed.

Objective: This study aimed to determine the independent and joint associations of sedentary time (ST) and physical activity (PA) with metabolic syndrome (MetS) and its components among Chinese adults. Methods: The study analyzed data from 4,865 adults aged ≥ 18 years who participated in the 2009 and 2015 China Health and Nutrition Surveys (CHNS). Four types of leisure ST and three types of PA self-reported at baseline were collected. Multivariable logistic regressions were used to determine the independent and joint associations of ST and PA with the odds of MetS or its components. Results: For independent effects, higher levels of television time and total leisure ST was associated with higher MetS risk [odds ratio ( Conclusions MVPA and total PA have independent preventive effects, and sedentary behavior (mainly watching TV) has an unsafe effect on MetS and its components. Strengthening the participation of MVPA and combining the LPA to replace the TV-based ST to increase the total PA may be necessary to reduce the prevalence of MetS in Chinese adults.

Objective:To investigate the effective constituents and mechanism of Tingli Dazao Xiefeitang for the treatment of heart failure through network pharmacology and high resolution mass spectrometry technique as well as molecular docking technique. Method:Chemical components and potential targets in Descurainiae Semen Lepidii Semen and Jujubae Fructus were searched by referring to literature and BATMAN-TCM database. The disease targets were searched in GeneCards database with ''heart failure'' as the key word. STRING platform was used to construct protein-protein interaction（PPI） network based on common targets of drugs and disease. The network topology was analyzed by using Cytoscape 3.7.2 software to obtain the core targets eventually. Kyoto encyclopedia of genes and genomes（KEGG） enrichment analysis of the core targets was conducted through DAVID database to draw a network of “herb-compound-target-pathway”. Based on the results of the network pharmacology research above，high resolution mass spectrometry was used to analyze the decoction and confirm the selected active components. AutoDock 4.2.6 software was used for molecular docking verification of key active components and related targets. Result:A total of 85 components were obtained in Descurainiae Semen Lepidii Semen，and 49 components were obtained in Fructus Ziziphi Jujubae. A total of 1 078 drug targets and 1 549 disease targets were identified. After PPI analysis and network topology analysis，23 core targets and 33 active components were obtained，involving 19 signaling pathways （P<0.05）. Mass spectrometry analysis results indicated that 18 components such as isovanillic acid，descuraininA and kaempferol-7-O-β-D-glucopyranoside were confirmed in decoction. Molecular docking analysis results indicated that 6 core components （degree value top 6），such as isovanillic acid，descurainin A and kaempferol-7-O-β-D-glucopyranoside，had good binding activity with silent information regulatory factor 1（SIRT1），interleukin（IL）1B，protein kinase Bα（AKT1） and tumor necrosis factor（TNF）. The compound recipe for heart failure mainly involved mitogen-activated protein kinase（MAPK），hypoxia inducible factor-1（HIF-1），Mammalian target of rapamycin（mTOR） and other signaling pathways. Conclusion:This study preliminarily investigated the effective constituents and mechanism of Tingli Dazao Xiefeitang in the treatment of heart failure. It can provide references for the precise clinical medication and screening of quality control markers，as well as the discovery of active components in the treatment of heart failure.

OBJECTIVE: To investigate the clinical features of pregnant women with thalassemia in non endemic area, and to prevent the births of babies with intermedia or major thalassemia. METHODS: Two hundred and thirty-five pregnants women with thalassemia diagnosed from March 2015 to April 2016 in our hospital were enrolled and retrospectively analysed. The blood routine and hemoglobin electrophoresis were performed respectively by XN-9000 automatic blood cell analyzer and HYDRASYS hemoglobin electrophoresis apparatus. The three commonest deletion of α-thalassemia, the three non-deletion α-thalassemia and 21 known β-thalassemia mutation were all detected by fluorescence melting curve analysis. RESULTS: Among 235 pregnant women of thalassemia, the majority were β-thalassemia, which were followed by α-thalassemia and composite thalassemia. Most pregnant women showed a mild anemia, and suffered from microcytic anemia, but less suffered from iron deficiency anemia. The ratio of second-child pregnant women was increased, and the ratio was close to one third both in α-thalassemia and β-thalassemia patients, and 75% patients were composite thalassemia. HbF was found to be more in native pregnant women with β-thalassemia. Hemoglobin isomer was easy to found in the pregnant with α-thalassemia, and they were all non native. The genotype of -- CONCLUSION More pregnant women with thalassemia are founded to be in non endemic area, and shows their own unique clinical features. It is certainly to detect thalassemia mutation in their spouse and their babies, to prevent the births of babies with intermedia or major thalassemia.

Objective To estimate the association between three B-vitamin intakes and sociodemographic factors among adults in China.Methods We derived our data from the China Health and Nutrition Survey (CHNS) among 12,241 individuals aged 18–64 years. Log binomial regression was used to estimate adjusted prevalence ratios for factors associated with the inadequate intake of B-vitamins.Results Females with low incomes and living in the north had a higher prevalence of inadequate riboflavin intake than those with high incomes and living in the south. Both males and females living in a village had a higher prevalence of inadequate riboflavin intake than adults living in a city. Adults with low income, low education, and living in the north or in a village had a higher prevalence of inadequate niacin intake than adults with a high income, high education, and living in the south or in a city.Conclusion We found that income, region, and area of residence were associated with riboflavin intake. Education, income, region, and area of residence were associated with niacin intake. Well-tailored strategies and policies are needed to improve nutritional status in China.

Objective To investigate the genetic characteristics of patients with thalassemia gene in Ningbo City.Methods Totally 313 patients with thalassemia gene diagnosed during March 2015 to April 2016 in Ningbo First Hospital were included in the study.The results of routine blood test,hemoglobin electrophoresis and gene test,as well as the gender and origin distribution of patients with thalassemia gene were analyzed.Results Of the 313 patients who carried the thalassemia gene,there were 289 females and 24 males with a median age of 29 years,ranging from 1 d to 57 years after birth.And of the 313 patients,75 carried the α-thalassemia gene,230 β-thalassemia and 8 composite thalassemia.The average value of hemoglobin was around 100 g/L and the average value of erythrocyte mean corpuscular volume (MCV) was less than 80 ft.Abnormal hemoglobin was usually found in α-thalassemia.81.74％ (188/230) of β-thalassemia had abnormal hemoglobin electrophoresis.Most of the patients were women who were diagnosed of anemia in routine prenatal examination.The number of patients,who came from Ningbo City or one of whose grandparents came from Ningbo City,was closed to 50％.Among 20 α-thalassemia patients coming from Ningbo City,genotype of--sea was the commonest genotype,accounted for 70.00％ (14/20).Among 82 β3-thalassemia patients coming from Ningbo,genotype of IVS-Ⅱ-654 was commonest genotype,accounted for 54.88％ (45/82).Genotypes of 2 composite thalassemia coming from Ningbo City were αcs compound IVS-Ⅱ-654 and-α3.7 compound CD41-42.Conclusions In Ningbo City,the incidence of thalassemia in women in Ningbo is higher than that in men.The morbidity of β-thalassemia genotype is apparently higher than that of α-thalassemia,and genotype of IVS-Ⅱ-654 in β3-thalassemia patients is the commonest genotype.

OBJECTIVE: To study the association between S100A8 expression and prognosis in children with acute lymphoblastic leukemia (ALL). METHODS: The clinical data of 377 children with ALL who were treated with the CCLG-2008-ALL regimen were retrospectively reviewed. ELISA and PCR were used to measure serum protein levels and mRNA expression of S100A8. The Kaplan-Meier method was used for survival analysis and a Cox regression analysis was also performed. RESULTS: The children were followed up for 56 months, and the overall survival rate of the 377 children was 89.1%. The prednisone good response group had significantly lower S100A8 protein and mRNA levels than the prednisone poor response group (P<0.01). In the children with standard or median risk, both S100A8 protein and mRNA levels were associated with event-free survival rate (P<0.05). There were significant differences in S100A8 protein and mRNA levels between the children with different risk stratifications (P<0.01). The children who experienced events had significantly higher S100A8 protein and mRNA levels than those who did not (P<0.01). The Kaplan-Meier survival analysis and the Cox regression model suggested that S100A8 overexpression was an independent risk factor for the prognosis of children with ALL. CONCLUSIONS High S100A8 expression may be associated with the poor prognosis of children with ALL and is promising as a new marker for individualized precise treatment of children with ALL.
