Objective:To investigate the awareness of Chinese gastroenterologists regarding the treatment targets of inflammatory bowel disease (IBD) as defined by the STRIDE-Ⅱ consensus and to identify challenges encountered in clinical practice.Methods:A nationwide cross-sectional survey was conducted via an online questionnaire distributed to gastroenterologists between February 16 and March 31, 2024. The survey encompassed demographic data, recognition and adherence to the STRIDE-Ⅱ consensus, perceived importance of IBD treatment targets, and clinical challenges.Results:A total of 203 valid questionnaires were collected from 28 provinces (autonomous regions/municipalities). The majority of participants (177/203, 87.2%) reported routinely referencing the STRIDE-Ⅱ consensus in IBD management. Over 90% of physicians identified endoscopic mucosal healing as the core treatment target. Additionally, approximately 80% emphasized the importance of clinical remission, endoscopic remission, quality-of-life improvement, disability prevention, and normalization of growth in pediatric patients. The challenges reported by more than half of physicians in acheiving the goals of the treatment process included lack of a standardized definition for mucosal healing (69.5%), management of psychological comorbidities (89.2%), drug failure (74.4%), penetrating Crohn's disease (72.4%), perianal fistulizing Crohn's disease (65.0%), and IBD management during pregnancy (61.1%).Conclusions:Chinese gastroenterologists demonstrate high awareness and adherence to the STRIDE-Ⅱ consensus, prioritizing mucosal healing as the cornerstone of IBD management. However, numerous challenges remain in clinical practice, particularly regarding operational definitions of therapeutic endpoints and complex disease phenotypes.

Objective:To explore the relationship between the personality traits and work-family conflict in Chinese adults and examine the roles of social support and self-efficacy in this relationship.Methods:A total of 2 079 working adults were selected and investigated with the Simplified Version of the Big Five Personality Scale(BFI-10),Work Family Conflict Scale(WFCS),Perceived Social Support Scale(PSSS),and General Self Efficacy Scale(GSES).The moderated mediating effect was tested by PROCESS.Results:The neuroticism scores were sig-nificantly positively correlated with the WFCS scores(r=0.11-0.19,P＜0.01),the scores of extraversion,agree-ableness and responsibility were significantly negatively correlated with the WFCS scores(r=-0.06--0.17,Ps＜0.01).The PSSS scores played a partial mediating role between neuroticism,agreeableness,responsibility scores and WFCS scores,the proportions of mediating effect were 17.03％,32.86％and 48.26％.The GSES scores mod-erated the relationship between WFCS scores and other personality traits(β=-0.07-0.04.Ps＜0.05),except for extroverted personality(β=-0.01,P＞0.05).Conclusion:Social support plays a mediating role between the per-sonality traits and work-family conflict,and the mediating effect is moderated by self-efficacy.

Objective:To develop clinical physicians′ health education competency assessment tool, so as to provide reference for competency-based capability enhancement management.Methods:Conduct a literature search using keywords such as " clinical physicians" " competency" " hospital health education" " health education competency" and " health education ability" to retrieve articles published between 2003 and 2023 in the China National Knowledge Infrastructure (CNKI) and PubMed databases. Through literature review, combined with the competency onion model, construct an initial pool of items for the clinical physicians′ health education competency scale (PHECS). From May to September 2023, expert consultation was used to screen items and form a test version of the scale. From November 2023 to January 2024, a purposive sampling method was used to recruit doctors from 2 comprehensive hospitals in Nanjing and 5 community health service centers in each district. A questionnaire survey was conducted using the test version of the scale, and scale validation was performed based on questionnaire data using item analysis and factor analysis, among other methods.Results:The constructed PHECS included three domains: knowledge, skills, and comprehensive quality, as well as ten dimensions: health education knowledge, clinical-related knowledge, health education program development, health education program implementation, health education program evaluation, organization and coordination, communication, personal traits and self-efficacy, motivation, and professional values, totaling 36 items. Confirmatory factor analysis indicated that the model fits well ( χ2/ df=2.438, RMSEA=0.078, CFI=0.937, TLI=0.928), and the PHECS had acceptable internal consistency (Cronbach′s α values range from 0.89 to 0.98) and good convergent validity ( AVE for each factor range from 0.71 to 0.94, and composite reliability ranges from 0.88 to 0.98). Conclusions:The PHECS developed in this study has good reliability, validity, and scientific merit, and can be used for competency-based management to enhance the health education capabilities of clinical physicians.

Tea green leafhopper(TGL),Empoasca onukii,is of biological and economic interest.Despite numerous studies,the mechanisms underlying its adaptation and evolution remain enig-matic.Here,we use previously untapped genome and population genetics approaches to examine how the pest adapted to different environmental variables and thus has expanded geographically.We complete a chromosome-level assembly and annotation of the E.onukii genome,showing nota-ble expansions of gene families associated with adaptation to chemoreception and detoxification.Genomic signals indicating balancing selection highlight metabolic pathways involved in adaptation to a wide range of tea varieties grown across ecologically diverse regions.Patterns of genetic vari-ations among 54 E.onukii samples unveil the population structure and evolutionary history across different tea-growing regions in China.Our results demonstrate that the genomic changes in key pathways,including those linked to metabolism,circadian rhythms,and immune system functions,may underlie the successful spread and adaptation of E.onukii.This work highlights the genetic and molecular basis underlying the evolutionary success of a species with broad economic impacts,and provides insights into insect adaptation to host plants,which will ultimately facilitate more sustain-able pest management.

Objective To investigate the value of detection of fetal cell-free fetal DNA(cff-DNA)in maternal plasma in the prenatal diagnosis of chromosomal abnormalities.Methods The plasma from 3200 gravidas(singleton with 20.3 ± 3.8 gestational weeks)was collected from April 1st 2011 to May 30th 2012.They were divided into 3 groups:(1)To tally 1720 cases were included in the high-risk serological screening group,in which women were younger than 35 years and got high-risk results in serological screening;(2)To tally 1310 cases were included in the advanced age group,in which women's age was more than 35 years;(3)To tally 170 cases were included in the supplementary group,in which women were younger than 35 years and got low-risk results in serological screening,or women who didn't take serological screening tests.All the 3030 gravidas in group 1 and 2 didn't take invasive prenatal diagnosis because of fear of abortion or short of prenatal diagnosis.Cff-DNA were detected by next generation sequencing in Shenzhen BGI Genomics Center for clinical laboratory.Amniocentesis and karyotype analysis were provided to the positive cases and women with negative results were followed-up by telephone.Results(1)The 3200 cases took cff-DNA detection,and 31 cases got positive results,including 27 cases of trisomy 21 and 4 cases of trisomy 18.Sixteen cases of trisomy 21 and 1 case of trisomy 18 were in the high-risk serological screening group.7 cases of trisomy 21 and 2 cases of trisomy 18 were in the advanced age group.Four cases of trisomy 21 and 1 case of trisomy 18 were in the supplementary group.(2)And the 84％(26/31)cff-DNA detecting positive cases received amniocentesis.In the 27 trisomy 21 positive cases,23 received amnioeentesis and got karyotype of 47XN,+ 21,with the diagnostic accordance rate of 100％.In the 4 cases who didn't take karyotype analysis,fetal anomaly(ventricular septal defect,dextrocardia and choroid plexus cyst)was found in 1 case before 20 gestational weeks;intrauterine fetal demise happened in 1 case before getting the result;2 other cases who already had healthy children took abortion in the local hospital without taking amniocentesis.In the 4 trisomy 18 positive cases,3 took amniocentesis,2 of which were trisomy 18 and took abortion,the other was chimera(46,XN/47,XN,+ 18)with only 2％ cells of trisomy 18,with no malformation found after delivery.Hypoevolutism(3 weeks less than gestational week),general hydropsy and intrauterine fetal demise happened before the other case took amniocentesis.(3)Follow up of cff-DNA negative cases:until May 30th 2012,no Down's baby was found in the 1230 cases with cff-DNA test negative results.Conclusions(1)The non-invasive fetal trisomy test(NIFTY)by next generation sequencing is a safe,accurate and high throughput method for the prenatal diagnosis of trisomy-21.(2)Use NIFTY as a further screening for pregnant women with high-risk serological screening results could lower invasive prenatal diagnosis rate.(3)Cases with positive NIFTY test results should receive amniocentesis and karyotype analysis to confirm the diagnosis before abortion.

Objective To investigate the immunoregulatory effect of thalidomide on the peripheral blood T-iymphocytes in systemic lupus erythematosus patients in vitro. Methods T-lymphoeytes were treated by thalidomide with different concentrations, then the proliferation of these T-lymphocytes proliferation was deteted by MTT while apoptosis and lymphocyte activation marker were analyzed by flow cytometry. The mRNA expression of IL-6, IL-10 and TNF-α was measured by real-time RT-PCR, One-way ANOVA was used for statistical analysis. Results In vitro, thalidomide inhibited the expression of CD3~+CD28~+ [500 μg/ml group vs the control group, (48±9)% vs (57±9)% P<0.05]. The pro-portion of apoptotic T-lymphoeytes in the 500 μg/ml group was (36±8)%, which was significantly higher than that in the control group [(23±5)%,P<0.05 ]. The values of A_(570nm) T-lymphocytes were significantly lower in the 100 μg/ml group, 300 μg/ml groupand 500 μg/ml group compared with those of the control group ( 100 μg/ml group vs 300 μg/ml group vs 500μg/ml group vs the control group, 0.39±0.05 vs 0.34±0.04 vs 0.30±0.03 vs 0.51±0.07, P<0.05), while thalidomide promoted the expression of CD8~+CD152~+ [ 100 μg/ml group vs 500 μg/ml group vs the control group, (5.0±0.6)% vs (7.8±0.7)% vs (4.2±0.6)%, P<0.05 ]. 500 μg/ml thalidomide inhibited the mRNA expression of IL-6, 2.5～500 μg/ml thalidomide inhibited IL-10, TNF-α mRNA expression of T-lymphocytes.Conclusion Thalidomide can inhibit the proliferative activities and CD28 expression of T-lymphocytes,reduce mRNA expression of IL-6, IL-10, TNF-α, stimulate CD28 expression and apoptosis of T-lymphocytes. These effects may play an important role in it's immune-suppressive effects on systemic lupus erythematosus.

Pain is one of the common clinical symptom, previous studies have implicated sodium channels as a key constituent in pain signaling. Sodium channel blockers with efficient sodium channel blockade effect play an important role in analgesic treatment. However, most drugs used in clinic have many drawbacks and can not meet the demand of the clinical use. Therefore, for the development of new generation of sodium channel blockers, it is of great significance to find small molecule sodium channel blocking lead compounds with novel chemical scaffolds and new structures, sodium channel blocking activity and structure-activity relationship are discussed in detail, and current problems and trends in future research are also emphasized.
