Objective To investigate the genetic characteristics of the VP1 region of Coxsackievirus A10 (CVA10) in Yunnan Province. Methods Fecal samples of suspected hand, foot and mouth disease (HFMD) were subjected to real-time fluorescent quantitative PCR for detection of enterovirus CVA10. Positive samples were subjected to VP1 gene sequence amplification and Sanger sequencing. Sequence splicing was performed with DNAstar7.1 Seqman software, and nucleotide sequence and amino acid site analysis were performed using Mega 6.0 software. Results The sequencing of VP1 gene of CVA10 obtained a sequence of 894 nucleotides, encoding 298 amino acids. Compared with the original strain, there were mainly three active amino acid mutation regions, 13-33, 141-142, and 283-285. The nucleotide difference rate between the Yunnan isolates and the reference strain ranged from 16.92% to 30.90%, and the amino acid difference rate ranged from 2.58% to 4.00%. C1 and C2 group nucleotide difference was 10.58%, and the amino acid difference rate was 1.80%. The VP1 150-176 region exhibited highly conserved characteristics. Six CVA10 strains and Sichuan strain MW178898 belonged to the C1 group of the C genotype. The other 14 CVA10 strains belonged to the C2 group. Conclusion VP1 gene mutation is active and CVA10 is an important pathogen of HFMD in Yunnan. C2 genotype of CVA10 is dominant in this study, and C1 and C2 have co-circulated in Yunnan. It is necessary to strengthen monitoring and develop multivalent vaccines containing CVA10 epidemic genotype.

Objective To observe the value of MRI for differential diagnosis of ovarian granulosa cell tumor(OGCT)and ovarian thecoma-fibroma(OTF).Methods Data of 37 females with OGCT(OGCT group)and 74 with OTF(OTF group)were retrospectively analyzed.MRI parameters were compared between groups.Multiple logistic regression analysis was performed,and the efficacy of each parameter alone and their combination for distinguishing OGCT and OTF were observed.Results Significant differences of cystic-solid classification,degree of cystic changes,the maximum diameter of cyst area of lesions,T2WI signal,enhancement degree and apparent diffusion coefficient(ADC)of the solid part of lesions,presence of honeycomb sign/cheese sign,presence of tumor blood vessels and bleeding were found between groups(all P＜0.05).Degree of cystic changes,ADC and presence of honeycomb sign/cheese sign were impact factors of MRI for distinguishing OGCT and OTF.The area under the curve(AUC)of the above three for distinguishing OGCT and OTF was 0.834,0.868 and 0.744,respectively,and of the combination was 0.934,greater than any alone(all P＜0.05).Conclusion MRI features such as degree of cystic changes,ADC and presence of honeycomb sign/cheese sign were helpful for distinguishing OGCT and OTF.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective:To introduce the Experience of Embodiment Scale(EES)and examine the validity and reliability in a sample of college students.Methods:Totally 1 254 college students(sample 1)were selected for en-try analysis and exploratory factor analysis,and 623 college students(sample 2)were selected for confirmatory fac-tor analysis,validity and internal consistency reliability tests,531 college students(sample 3)were selected for re-testing at a 4-week interval.The Body Esteem Scale for Adolescents and Adults(BESAA),Socio-Cultural Attitudes Toward Appearance Questionnaire(SATAQ-4),Eating Disorder Examination Self-Assessment Questionnaire 6.0(EDE-Q6.0),and Brief Symptom Inventory(BSI-18)were used as validity scales.Results:The EES had 31 items divided into 6 factors,which explained 69.53％of the total variance,and the factor loadings of each item ranged from 0.61 to 0.87.Confirmatory factor analysis revealed a model fit was good(x2/df=2.63,CFI=0.82,TLI=0.80,SRMR=0.07,RMSEA=0.08).The EES scores were positively associated with the BESAA scores(r=0.59,P＜0.01),and negatively correlated with the scores of SATAQ-4,EDE-Q6.0 and BSI-18(r=-0.54,-0.44,-0.47;P＜0.01).The Cronbach α coefficient of the total scale was 0.90,and ICC of retest was 0.88.Conclusion:The Chinese version of the EES has good validity and reliability and could be used to measure the embodied experience of college students.

Objective To investigate the current postoperative physical activity levels of lung cancer patients after a month and to analyze the influencing factors.Methods From January to December 2023,a total of 1,195 lung cancer patients from 16 hospitals in eastem,central and westem China were selected as the survey subjects by the convenient sampling method.A cross-sectional survey was conducted by General Information Questionnaires,Health-Related Physical Fitness Surveys,MD Anderson Symptom Inventory,Hospital Anxiety and Depression Scale,Social Support Rating Scale,Self-Rated Abilities for Health Practices Scale,and the International Physical Activity Questionnaire.Results 36 questionnaires with missing data exceeding 10％and 13 duplicate questionnaires were excluded,resulting in the analysis of 1,146 questionnaires.After a month postoperatively,lung cancer patients with moderate and low levels of physical activity were 732(63.9％)and 204(17.8％),respectively.Multivariate regression analysis showed that the influencing factors included residence,average monthly family income,regional lymph node staging,family history of lung cancer,grip strength,hemoglobin,and depression score(P＜0.05).Conclusion The physical activity level of lung cancer patients a month after surgery is influenced by a combination of sociodemographic,disease-related,health-related physical fitness,and psychological factors.Clinical healthcare professionals should accurately assess the physical activity levels of lung cancer patients,identify those with insufficient physical activity,and develop and implement personalized intervention strategies based on their physical condition and potential influencing factors to enhance their physical activity levels and improve their quality of life.

Objective To construct a theoretical model of venous thromboembolism(VTE)risk perception in pregnant women,so as to provide a scientific basis for promoting pregnant women to form a correct risk perception of VTE and actively take preventive behaviors.Methods A qualitative research approach guided by the procedural grounded theoiy was adopted.Data were collected by a semi-structured deep interview on 18 pregnant women who received prenatal examination in the outpatient department of a tertiary A obstetrics and gynecology hospital in Nanjing from June to July 2023,and the data were analyzed by three-level coding and continuous comparison method.Results The VTE risk perception of pregnant women was affected by 6 factors including social coupling system,self health status,life behavior habits,knowledge on disease,compliance behavior and emotional stimulation.Pregnant women perceived VTE risk from 3 aspects:threats to maternal and child safety,increased family economic burden and increased time cost,impact on social roles.Thus,3 health behavior decisions were formed,including taking preventive behaviors,overcoming implementation barriers,and seeking knowledge behaviors,in order to reduce their own risk of VTE,and prevent the occurrence of VTE.Conclusion The theoretical model of VTE risk perception of pregnant women can guide medical staff to comprehensively consider the influencing factors of VTE risk perception of pregnant women,optimize the form and content of VTE health education,give pregnant women individualized and sustainable VTE prevention guidance,and strengthen pregnant women's perception of VTE risk and the benefits of preventive behavior,so as to actively take the correct health behavior decisions.

Objective:To establish an epidemiological cut-off value (ECV) for antifungal drugs against Cryptococcus neoformans in East China through a multicenter in vitro drug susceptibility test. Methods:A retrospective collection of 479 clinical isolates of Cryptococcus neoformans was conducted by the East China Invasive Fungal Infection Group (ECIFIG) from January 1, 2017 to December 31, 2022. Mass spectrometry and gene sequencing were used for identification. A unified drug susceptibility testing system was established in the fungal laboratories across three sub centers in Shanghai, Jiangxi, and Jiangsu provinces.

Objective:To investigate the teaching effect of blended teaching mode based on BOPPPS in the teaching of Natural Medicinal Chemistry.Methods:The undergraduate students of grade 2019 majoring in pharmacy of a medical college were selected as the research objects and divided into 2 groups randomly.Students in class 2 were set as the control group(n=27)and students in class 1 were set as the experimental group(n=29).The students of the two classes were taught by the same group of teachers.The control group adopted traditional teaching methods and classroom teaching as the main teaching mode combines with multimedia teaching.The experimental group received blended teaching mode based on BOPPPS.The final examination scores,teaching effects and student satisfaction of the two groups were compared and analyzed.Results:The survey results showed that the teaching effect of the blended teaching model based on BOPPPS was recognized by 96.55%of the students in the experimental group.The final examination score in the experimental group was higher than that in the control group(P＜0.05).The teaching effect of the experimental group was significantly better than that of the control group(P＜0.05),and the satisfaction of students in the experimental group was higher than that in the control group(P＜0.05).Conclusion:The application of blended teaching mode based on BOPPPS in the teaching of Natural Medicinal Chemistry can effectively stimulate students'learning interest and improve the teaching quality.

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.

Purpose To explore the application and clini-copathological significance of molecular classification in endome-trial cancer(EC)of WHO(2020)tumors of the female repro-ductive system.Methods Sixty-two EC patients were collected and categorized into four subgroups,namely POLE mutation type,mismatch repair deficient(MMRd)type,non-specific molecular spectrum(NMSP)type,and p53 mutation type,based on WHO molecular classification tested by PCR and im-munohistochemistry.The correlation among four molecular sub-groups and their clinicopathological features were analyzed.Re-sults The molecular classification was distributed as follows:3(4.8％)cases were POLE-mutated,15(24.2％)cases MMRd,36(58.1％)cases NSMP and 8(12.9％)cases p53 abnormal expression.There were no significant differences a-mong POLE-mutated and infiltration depth,grade,lymph vascu-lar space invasion and other pathological factors such as lymph node metastasis and FIGO stage(P＞0.05).Among 15 patients with MMRd,the proportion of FIGO stage Ⅱ+Ⅲ significantly increased.One case showed abnormal overexpression of p53 pro-tein,while two cases showed complete loss of expression in MMRd subgroup.36 cases of NSMP were associated with low histopathological grade(Grade Ⅰ+Ⅱ)(P＜0.05),and no significant differences were observed among NSMP and other clinicopathological factors(P＞0.05).The p53 abnormal ex-pression in 8 cases was related to high histopathological grade(Grade Ⅲ)(P＜0.05),and the rate of lymph node metastasis and FIGO stage Ⅱ+Ⅲ significantly increased in patients with p53 abnormal expression,and although the difference was not statistically significant(P＞0.05).Conclusion The molecu-lar subgroups of EC have certain clinical application value,the cases with MMRd and p53 abnormal expression may have poor prognosis than these with POLE-mutated and NSMP.
