[Purposes]This paper analyzes the topics of the highly read posts in new media of laboratory medical journals,to reveal the hotspots and preferences of users,and guide the formulation of post topic optimization strategy,aiming at improving the dissemination power and influence of new media of laboratory medical journals.[Methods]Taking the WeChat official account of"Laboratory Medicine"(referred to as"Laboratory Medicine")as an example,we used Python programming to screen out the top 100 read posts published on its platform from January 1,2018 to May 31,2023.Based on the Latent Dirichlet Allocation model,we identified the topics of the 100 posts and analyzed them,and then proposed a corresponding post topic optimization strategy for new media of laboratory medical journals.[Findings]The topics of the highly read posts of"Laboratory Medicine"are"Policy document on nucleic acid detection for prevention and control of COVID-19","Code of conduct in the medical industry",and"Professional qualification examination and continuing education".Based on the topic identification and analysis,the topic optimization strategy of multi-voice polyphony(serialized sub-topic development,topic deduction from new perspectives,and case topic collection)is proposed.This strategy is to stretch the narrative tension of the topic of posts,from text telling to retelling text,to enhance the depth and breadth of the topic of new media posts of laboratory medicine journals.[Conclusions]By identifying and analyzing the research topic of the highly read posts on"Laboratory Medicine",it is helpful to formulate more accurate optimization strategies for the topic of posts and provides a basis for the research innovation and spatial expansion of the future topic of the highly read posts of new media of laboratory medical journals.

OBJECTIVE:To investigate the puberty timing status and its correlation with obesity in 8 - 19 year-old students in the urban area of Chongqing.METHODS:A total of 3046 primary and middle school students were recruited by using multiple-stage stratified cluster sampling method. The pubertal growth spurt in the students was evaluated by Pubertal Development Scale (PDS), and the physical examination, including body height, weight, the external genitalia, testicular volume and pubic hair of boys, and the breast and pubic hair of girls. The age of each stage was calculated by the method of Probability unit regression, and whether the pubertal start earlier being related to obesity was analyzed by the Spearman rank correlation.RESULTS:The average age of breast to B2 phase, pubic hair to FP2 phase and the menarche for girls were at 11.51, 13.93 and 12.29 year-old respectively. The average age of genitalia to G2 phase, pubic hair to MP2 phase, the volume of testicular to 4 ml and the first nocturnal emission for boys were at 13.13, 13.62, 11.67 and 13.57 year-old respectively. Among girls, the proportion of overweight or obesity was higher in the earlier puberty group than those in the normal development group, and existing a rank correlation (P < 0.01).CONCLUSION:The earlier puberty timing and advanced sexual development were obvious in girls, which may correlate with the factors of obesity.

Objective To evaluate reliability and validity of the Multidimensional Sub-health Questionnaire of Adolescents(MSQA).Methods The stratified cluster random sampling was taken for choosing 1 522 middle school students from Chongqing Three Gorges reservoir areas.All the students were surveyed with MSQA,and one week later,218 of them were re-tested with the MSQA and also with Symptom Check List-90(SCL-90) and Cornell Medical Index(CMI).Test-retest reliability and internal consistency reliability were used to evaluate reliability of MSQA,and construct validity and criterion-related validity were used to evaluate validity of MSQA.Results The test-retest correlation coefficients of whole questionnaire,somatic sub-health domain,mental sub-health domain and each dimension were 0.941,0.926,0.901,0.838,0.822,0.831,0.923,0.913 and 0.934 respectively(P0.01).The Cronbach′s α coefficient and split-half reliability coefficient of whole MSQA questionnaire were 0.961 and 0.938 respectively.The Cronbach′s α coefficient of each dimension and each domain of MSQA were 0.711~0.921,while split-half reliability coefficient were 0.697~0.915.The correlation coefficient of each dimension and its domain were 0.813~0.952(P0.01).The correlation coefficient between total score of mental symptom of SCL-90 and total score of mental sub-health domain of MSQA was 0.766(P0.01).The correlation coefficient between total score of somatic sub-health of CMI and total score of somatic sub-health of MSQA was 0.575(P0.01).Conclusion MSQA has a good reliability and validity,and it may be taken as an instrument to assess sub-health of middle school students of Three Gorges reservoir areas.
