As the core vehicle for preserving and transmitting traditional Chinese medicine（TCM） academic thought and clinical experience， the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine， this study conducted a comprehensive analysis of critical challenges， including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic， encompassing three dimensions of authenticity and standardization， characteristics and advantages， application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment， while aligning with modern scientific research standards， achieving a balance between individualized TCM experience and standardized evaluation. Concurrently， this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases， contributing significantly to the inheritance of TCM knowledge， evidence-based practice， and the reform of talent evaluation mechanisms.

Objective: To analyze the correlation between the levels of vitamin A, vitamin D, vitamin E with body fat mass percentage(FMP) as well as lifestyle factors among primary school students, so as to provide references for exploring the vitamin nutritional status of primary school students and its potential influencing factors. Methods: From September 1 to October 30, 2021, a cluster sampling method was used to select 750 thirdgrade students from eight primary schools in Luohu District, Shenzhen. Their body composition was measured, and blood samples were collected to detect the serum levels of vitamin A, vitamin D, and vitamin E using a mass spectrometer. Dietary and exercise habits were collected through questionnaires. Mann-Whitney U test and Kruskal-Wallis H rank sum test were used for inter group comparisons, spearman correlation was used for correlation analysis,and Logistic regression model was used to analyze the association between lifestyle and vitamin content. Results: The overall level of vitamin A in school aged children was 0.4 (0.4, 0.5) mg/L, with a deficiency rate of 0 and a marginal deficiency rate of 5.1%; the level of vitamin D was 26.0 (22.0, 30.0) ng/mL, with a deficiency rate of 0.4% and an insufficiency rate of 12.7%; the content of vitamin E was 11.8 (10.1, 13.5) mg/L, with an insufficiency rate of 0.8%. Spearman correlation analysis showed that vitamin A was positively correlated with FMP in the total population, boys, girls, and normal weight population ( r =0.18, 0.18, 0.20, 0.10), and vitamin D was positively correlated with FMP in the total population and obese population ( r =0.08,0.16)(all P <0.05). Logistic regression analysis showed that marginal deficiency of vitamin A was associated with consumption of animal, snack, and dairy/egg/bean foods ( OR =0.45, 0.55, 0.59); whether vitamin D was deficient was influenced by gender ( OR =2.65) and exercise ( OR = 1.96 ) (all P <0.05). Conclusion Vitamin A, vitamin D and vitamin E levels are associated with body fat percentage, with significant variations in vitamin status among individuals of different body types, necessitating targeted supplementation.

Aim To explore the possible regulatory effect of leptin on acyl-CoA synthetase long chain fami-ly member ACSL5 and their effect on migration and in-vasion of breast cancer cell,and to explore the underly-ing mechanism.Methods The expression of leptin receptor was detected by immunofluorescence assay.The migration and invasion ability of MCF-7 cells were detected by wound healing assay and Transwell assay respectively.The downstream target gene of leptin was analyzed by PCR microarray data.The expression of ACSL5 in breast cancer and its correlation with the staging and prognosis of breast cancer patients were as-sessed uing bioinformatics methods.The expression of ACSL5 in MCF-7 cells treated with different concentra-tions of leptin was detected using real time fluorescence quantitative polymerase chain reaction(RT-qPCR).Overexpressing ACSL5 was constructed by lentiviral transfection;the expressions of EMT related proteins,AMPK-α and p-AMPK-α were detected by Western blot.Results Leptin promoted breast cancer cell mi-gration and invasion and EMT.ACSL5 was significant-ly low expressed in breast cancer and related to progno-sis.Leptin downregulated the expression of ACSL5 through OBR.Leptin activated AMPK pathway to downregulate ACSL5 and promote migration,invasion and EMT of breast cancer cells.Conclusions Leptin may promote the migration,invasion and EMT of breast cancer by downregulating ACSL5 through activating AMPK pathway.

Objective To compare the blood flow perfusion area in different retinal vascular plexuses between adults and children using swept-source optical coherence tomography angiography(SS-OCTA)and explore the correlation of the retinal blood flow perfusion area with spherical equivalent(SE)and axial length(AL).Methods A total of 112 partici-pants,including 58 children(116 eyes,aged 8-13 years)and 54 adults(108 eyes,aged 18-30 years),were recruited from Eye Hospital,Wenzhou Medical University from December 2020 to December 2024.Based on SE,these children and adults were further divided into the emmetropia(-0.50＜SE ≤+0.50 D),low myopia(-3.00＜SE≤-0.50 D),and moderate myopia(-6.00＜SE≤-3.00 D)groups.SS-OCTA was used to acquire the perfusion area data across retinal vascular layers.The inner vascular network of the retina was subdivided into the peripapillary radial vascular network,su-perficial vascular plexus(SVP),middle vascular plexus(MVP),and deep vascular plexus(DVP).The blood flow perfu-sion areas across retinal vascular layers were compared between adults and children.Pearson correlation analysis was per-formed to assess the correlation of the blood flow perfusion areas across retinal vascular layers with AL and SE in adults and children,respectively.Results SE was negatively correlated with AL in both adults and children(r=-0.781 and-0.667,respectively;both P＜0.001).The total inner retinal perfusion area was negatively correlated with AL in both adults and children(r=-0.239 and-0.299,respectively;both P＜0.05).In children,the perfusion area in the peripapil-lary radial vascular network,SVP,and DVP was negatively correlated with AL(r=-0.443,-0.315,and-0.220,respec-tively;all P＜0.05).In adults,the perfusion area in SVP,MVP,and DVP was negatively correlated with AL(r=-0.243,-0.230,and-0.364,respectively;all P＜0.05).Adults with low/moderate myopia exhibited a significantly larger perfu-sion area in the peripapillary radial vascular network compared with children with corresponding myopia levels,and the differences were statistically significant(both P＜0.001).Conclusion There were significant differences in the perfu-sion area of the peripapillary radial vascular network between adult and pediatric myopic patients.AL showed the strongest correlations with the perfusion area of the peripapillary radial vascular network in adults and the perfusion area of DVP in children,respectively,suggesting distinct effects of retinal vascular layers at different stages of ocular growth.

Glycoengineering was carried out in the mammalian cell line CHO for the production of pro-tein-based drugs.Firstly,the genome sequence of the Rosa26 locus of CHO cells was determined,the gRNA sequences were designed,and the landing pad was integrated into the Rosa26 locus of CHO cells by CRISPR/Cas9 technology.Three targeting vectors co-expressed by glycosyltransferases,which are β-1,4 galactosyltransferase(B4GALT1),α-2,6-sialyltransferase 1(ST6GAL1)and N-acetaminoglycosyl-transferase Ⅲ(GnT Ⅲ),were constructed by overlapping PCR and seamless ligation technology,and the three glycosyltransferase genes were integrated into the CHO Rosa26 locus by Cre enzyme-mediated cassette exchange technology.PCR confirmed that three glycosyltransferases had been successfully site-directed integrated into the Rosa26 site.The mRNA expression levels of the three glycosyltransferases were more than 50 000-fold by qRT-PCR,and the protein expression levels of the three glycosyltrans-ferases were more than 4-fold via western blotting(P＜0.001).A CHO-engineered cell line with three glycosyltransferases integrated into Rosa26 site was successfully constructed.

Objective:To analyze the characteristics of anonymous online dating and related factors of not being tested for HIV among men who have sex with men and to provide the basis for developing targeted HIV prevention strategies and intervention measures.Methods:Using a cross-sectional study design, respondents were recruited with the assistance of MSM social organizations from April to July 2023 in eight cities in Shandong Province. Snowball sampling, activity venues, and networks were employed, targeting a sample size of 400 people per city. A face-to-face questionnaire survey collected data on sociodemographic characteristics, drug use, sexual intercourse, and online informed dating. Blood samples were also collected for HIV and syphilis antibody testing.Results:In the past six months, 2 787 MSM sought homosexual partners through the Internet, and 78.26% (2 181/2 787) chose to make anonymous online dating. Before having homosexual sex with online sexual partners, 10.41% (290/2 787) of them did not ask each other about HIV infection status and 33.37% (930/2 787) of them not being tested for HIV. There were statistically significant differences in the distribution of age, marital status, household registration, education level, sexual orientation, ways to find male sexual partners, not asking online sexual partners about their HIV status before sexual intercourse, no mutual HIV testing with online sexual partners before sexual intercourse, and syphilis antibody between anonymous and non-anonymous online dating persons (all P<0.05). The results of multivariate logistic regression analysis showed that <25 years old (a OR=1.43, 95% CI: 1.15-1.77) and ≥35 years old age group (a OR=1.61, 95% CI: 1.29-2.01), people with no AIDS knowledge (a OR=2.37, 95% CI: 1.25-4.49), drug users (a OR=1.38, 95% CI: 1.17-1.63), online dating anonymous (a OR=2.19, 95% CI: 1.76-2.73), HIV antibody positive (a OR=3.61, 95% CI: 2.22-5.88) and no intervention services in the last 1 year (a OR=1.58, 95% CI: 1.05-2.38) were the related factors of MSM not being tested for HIV before having sexual intercourse through online dating. Conclusions:The phenomenon of anonymous online dating was common among MSM in Shandong Province, and the proportion of MSM not being tested for HIV before having sexual intercourse through anonymous online dating was relatively high. It is necessary to strengthen health publicity and promote informed dating in MSM.

The anterior cingulate cortex (ACC) has recently been proposed as a key player in the representation of itch stimuli. However, to date, little is known about the contribution of specific ACC interneuron populations to itch processing. Using c-Fos immunolabeling and in vivo Ca²⁺ imaging, we reported that both histamine and chloroquine stimuli-induced acute itch caused a marked enhancement of vasoactive intestinal peptide (VIP)-expressing interneuron activity in the ACC. Behavioral data indicated that optogenetic and chemogenetic activation of these neurons reduced scratching responses related to histaminergic and non-histaminergic acute itch. Similar neural activity and modulatory role of these neurons were seen in mice with chronic itch induced by contact dermatitis. Together, this study highlights the importance of ACC VIP⁺ neurons in modulating itch-related affect and behavior, which may help us to develop novel mechanism-based strategies to treat refractory chronic itch in the clinic.

With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

In recent years, the reform of the registration, evaluation, and approval system for traditional Chinese medicine(TCM) has been promoted at the national level, with establishment of an evaluation evidence system for TCM registration that combines TCM theory, human use experience, and clinical trials(known as the "three-combined" evaluation evidence system). This system, which aligns with the characteristics of TCM clinical practice and the laws of TCM research and development, recognizes the unique value of human use experience in medicine and returns to the essence of medicine as an applied science, thus receiving widespread recognition from both academia and industry. However, it meanwhile poses new and higher challenges. This article delves into the value and challenges faced by the "three-combined" evaluation evidence system from three perspectives: registration management, medical institutions, and the TCM industry. Furthermore, it discusses how the China Association of Chinese Medicine, leveraging its academic platform advantages and leading roles, has made exploratory and practical efforts to facilitate the research and development of new TCM drugs and the implementation of the "three-combined" evaluation evidence system.
