Irritable bowel syndrome （IBS） is a functional bowel disorder characterized primarily by abdominal pain and altered defecation habits. In recent years， traditional Chinese medicine （TCM） has made progress in multiple aspects of IBS research and treatment， including syndrome distribution， development of TCM formulas， clinical efficacy evaluation， external therapies， and psychosocial regulation. However， it still faces challenges such as over-reliance on symptomatic manifestations rather than biomarkers for diagnostic criteria， and the lack of high-quality evidence-based data supporting the efficacy of TCM formulas in treating IBS. This paper proposed that TCM diagnosis and treatment of IBS should adhere to the strategy of integrating the holistic concept with syndrome differentiation and treatment， combining TCM external therapies such as acupuncture， moxibustion and acupoint application）， and emphasizing individualized diagnosis and treatment for psychosomatic abnormalities. Future research should integrate multi-omics technologies， artificial intelligence and other methods to deepen the understanding of the pathogenesis of IBS and the mechanisms of TCM formulas， so as to promote the standardization and internationalization of TCM in the diagnosis and treatment of IBS.

Objective To investigate the clinical efficacy of Yinhuo Guiyuan moxibustion as an adjunc-tive therapy to Yaotongning Capsules in treating kidney deficiency-related lumbago in patients with stage 3-4 chronic kidney disease.Methods Sixty patients with stage 3-4 chronic kidney disease admitted from Janu-ary 2021 to June 2023 were randomly divided into a control group and an observation group,with 30 cases in each group.Both groups received basic treatment interventions during the study period.The control group re-ceived Yaotongning Capsules orally,while the observation group received additional Yinhuo Guiyuan moxibus-tion therapy.Clinical efficacy,pain scores,renal function indicators,satisfaction scores,and adverse reaction rates were compared between the two groups.Results The total effective rate was significantly higher in the observation group(93.33％)than in the control group(73.33％,P＜0.05).At the 4th,8th,and 12th weeks of treatment,the VAS scores of both groups were lower than baseline values,with the observation group dem-onstrating significantly lower scores compared to the control group at the same time points(P＜0.05).After treatment,both groups showed reductions in BUN,Scr,and 24hUP levels,with the observation group showing lower levels than the control group(P＜0.05).The observation group demonstrated higher satisfaction scores than the control group(P＜0.05).No significant difference was found in adverse reaction rates between groups(x2=0.218,P=0.640).Conclusion Yinhuo Guiyuan moxibustion combined with Yaotongning Cap-sules is effective in treating stage 3-4 chronic kidney disease patients,effectively alleviating low back pain,improving renal function indicators,enhancing treatment satisfaction,with lower incidence of adverse reac-tions.

Objective To compare the positioning errors and the motion of acromioclavicular joint in breast cancer patients with integrated cervicothoracic thermoplastic membrane and breast bracket fixation,and to provide reference for accurate irradiation of upper and lower clavicular region.Methods Sixty-three pa-tients with breast cancer who were treated in the radiotherapy center of the hospital from November 1,2021 to August 9,2023 were selected as the study objects,and were divided into the integrated cervicothoracic thermo-plastic membrane group(n=32)and breast bracket group(n=31)according to different positioning meth-ods.The translation errors of left and right direction(X),head and foot direction(Y)and ventral and dorsal direction(Z)and the rotation errors of sagittal plane(Rx),cross section(Ry)and coronal plane(Rz)of the two groups were analyzed,and the movement amplitude and three-dimensional displacement of acromioclavic-ular joint were measured respectively.Results Compared with the breast bracket group,X translation errors[(0.18±0.14)cm vs.(0.15±0.12)cm]and Z translation errors[(0.19±0.14)cm vs.(0.16±0.14)cm]of the cervicothoracic thermoplastic memberane group were greater,Z translation error[(0.21±0.17)cm vs.(0.22±0.21)cm]and Rx rotation error of cervical and sternoclavicular joints[(0.93±0.87)° vs.(1.08±0.92)°]were smaller,Rz rotation error[(1.00±0.94)° vs.(0.95±0.86)°]was greater,and the motion ΔX of acromioclavicular joint[(0.18±0.15)cm vs.(0.25±0.21)cm]was smaller,the difference was statistically significant(P＜0.05).Conclusion Integrated cervicothoracic thermoplastic membrane can be used as a solu-tion for prophylactic irradiation of breast cancer in the upper and lower clavicular region and for radiation leak-age in the presence of metastasis.

China is a country with a high incidence of esophageal cancer.The pathological type is mainly squamous cell carcinoma.Squamous intraepithelial neoplasia is the most recognized precancerous lesion of esopha-geal squamous cell carcinoma,and its monitoring and intervention is an effective method to reduce the incidence of esophageal squamous cell carcinoma and improve the quality of life of patients.Understanding the etiology,clinical features,diagnosis and treatment of esophageal squamous cell carcinoma plays a crucial role in the prevention and early diagnosis and treatment of esophageal squamous cell carcinoma.At present,the clinical research related to esophageal squamous intraepithelial neoplasia is still insufficient,and there are some differences in clinical treat-ment.This review summarizes the risk factors,clinical features,diagnosis,prognosis and treatment of esophageal squamous intraepithelial neoplasia,hoping to provide ideas for the clinical management of esophageal squamous intraepithelial neoplasia.

Based on the sampling survey data of 11 164 medical researchers in China, this paper analyzed the understanding, attitude and compliance of medical researchers on scientific research ethics in China. The survey found that although most medical researchers claim to have more understanding of scientific research ethics, the level of understanding of scientific research ethics is not optimistic; the channels to scientific research ethics knowledge are diversified, but the standardized training channels are insufficient; most researchers held the positive attitude toward following the ethical norms, but those male, youth under 35, with senior professional titles, or from northeast China held negative attitude relatively; more than half of the researchers claimed that the supervision of research ethics in China was basically in place, but some people said that the violation of scientific research ethics was common, and some researchers reported that there was a phenomenon of "direct seal consent and reply" in ethical review. Compared with medical institutions, enterprises and universities are the weak links of scientific research ethics training, education and review. Based on the above actuality, it puts forward policy suggestions to strengthen the scientific research ethics training and ethics review requirements.

The cognition and attitude of scientific research ethics consciousness affect the willingness and degree of individual researchers to follow research ethics norms. This study investigated the awareness, access and training needs of Chinese medical researchers (n=11 164) on the knowledge of scientific research ethics. The survey found that more than 50.0% of people were aware of the "golden rice incident" and "skull transplantation"; 80.0% of people were knew of Operational Quideline for the Ethic Review of Biomedical Research Involving Human Subject; 90.0% said that "respecting people" and "not harming" were the basic ethical principles, but 42.8% and 75.1% chose "beneficial" and "fair" respectively; more than 60.0% of people have acquired scientific research ethics knowledge through "self-study", "special training organized by units" or "words and deeds taught by mentors or colleagues", but still 30.0% have not participated in scientific research ethics lectures in recent three years; In terms of training needs, more than 50.0% chose "ethical norms for research and application", followed by "frontier ethical issues" (41.0%) and "ethical review" (36.7%). Based on this, this paper puts forward some suggestions to improve the content and form of scientific research ethics education and training in China.

Hair loss affects millions of people at some time in their life, and safe and efficient treatments for hair loss are a significant unmet medical need. We report that topical delivery of quercetin (Que) stimulates resting hair follicles to grow with rapid follicular keratinocyte proliferation and replenishes perifollicular microvasculature in mice. We construct dynamic single-cell transcriptome landscape over the course of hair regrowth and find that Que treatment stimulates the differentiation trajectory in the hair follicles and induces an angiogenic signature in dermal endothelial cells by activating HIF-1α in endothelial cells. Skin administration of a HIF-1α agonist partially recapitulates the pro-angiogenesis and hair-growing effects of Que. Together, these findings provide a molecular understanding for the efficacy of Que in hair regrowth, which underscores the translational potential of targeting the hair follicle niche as a strategy for regenerative medicine, and suggest a route of pharmacological intervention that may promote hair regrowth.

In order to improve the effectiveness of private class inquiry with the development of information teaching, the smart teaching platform has been established, with instructional management, curriculum setting, teacher preparation, classroom application, supervision and monitoring modules. Taking the platform as the medium, the small class inquiry learning community of entity curriculum is constructed between students and the teachers. In the eight-year medical teaching, the content of learning cycle is designed according to the entity curriculum, which is issued on cloud platform before class, in class and after class. Students learn basic concepts by themselves in the learning community, explore the application of knowledge under the guidance of teachers, and expand knowledge in class or after class. After having test in teaching procedure, the small class learning community based on smart teaching cloud platform has a submission rate, interaction rate and score rate of more than 90%. It can not only make full use of the advantages of information-based teaching resources, but also build face-to-face learning community in the course teaching, reflecting the emotional interaction of personalized teaching. It's suggested that new approaches to teaching should be student-centered and activity-based, engaging students actively in the learning process, which can promote students' autonomous learning ability and innovative thinking ability.

Objective:To report the sampling study design and radiography protocol of a large-sample investigation on skeletal maturation of 3 to 18-year-old children in China.Methods:Multi-stage stratified random sampling was employed in this study. Two provinces, municipalities, or autonomous regions were randomly selected from each of the seven regions of China, including Northeast China, Northwest China, North China, Central China, East China, Southwest China, and South China. Then one rural and one urban investigation site were randomly selected from each province, municipality, or autonomous region. In total 28 sites were included. Among those sites, four residential districts were randomly selected from each urban site, and four townships from each rural site. For each residential district or township, 1-4 kindergartens, primary schools, and middle schools were chosen. Random cluster sampling was used to extract 3-<6-year-old children in kindergartens, and 6-18-year-old children in primary schools and middle schools. The investigation on skeletal maturation was sampled proportionate to the sampling of the whole study. The estimated simple size was 780 for each site, and 21 840 for all 28 sites in total. There were six groups of 3-<6-year-old children classified at 0.5-year intervals, and 12 groups of 6-18-year-old children classified at 1-year intervals. Posteroanterior position radiography of the left hand and wrist was achieved for all subjects.Results:The study was performed from August 26, 2019 to October 16, 2021. In total, 20 444 children received posteroanterior position radiography of the left hand and wrist, including 10 196 males and 10 248 females, 9 711 urban and 10 733 rural, respectively. The 3-<6-year-old group included 1 611 (male 819, female 792) subjects, and the 6 to 18-year-old group included 18 833 (male 9 377, female 9 456) subjects.Conclusion:This nationwide investigation on skeletal maturation of 3 to 18-year-old children in seven regions of China was successfully preformed. The results of this study can provide an important reference for establishing the current evaluation criteria of bone age in Chinese children and adolescents.
