ObjectiveTo explore the current status and issues regarding the application of ancient books in clinical practice guidelines and expert consensus of traditional Chinese medicine （TCM） published in China， and to provide methodological recommendations for the incorporation of ancient books in the development of TCM guidelines. MethodsWe searched China National Knowledge Infrastructure （CNKI）， WanFang Data， VIP， SinoMed， PubMed， Embase， as well as six industry websites including China Association of Chinese Medicine， National Group Standards Information Platform， and Chinese Association of the Integration of Traditional and Western Medicine，etc. TCM clinical practice guidelines or expert consensus issued during January 1st， 2017， to November 26th， 2022 were searched. Clinical practice guidelines or expert consensus that explicitly referred to ancient books were included， and the content regarding the searching for ancient books， sources of access to ancient books， methods of evaluating the level of evidence， methods of evaluating the level of recommendation， and methods of evaluating the evidence for the ancient books were analysed. ResultsA total of 1,215 TCM clinical practice guidelines or expert consensus were retrieved， with 442 articles explicitly mentioning the application of ancient books， including 300 （67.87%） clinical practice guidelines and 142 （32.13%） expert consensus. Sixty of the 442 publications explicitly reported that ancient books searching had been conducted （13.57%）； among these 60 publications 27 （45.00%） explicitly reported ancient books searching strategies， and the most frequent method was manual searching with a total of 24 articles （40.00%）. The most popular search source was Chinese Medical Dictionary， a TCM classics database， with a total of 18 articles. 197 articles （44.57%） explicitly reported the evaluation criteria for the level of evidence， of which 141 articles （71.57%） involved the evaluation criteria for the ancient books； 413 articles （93.44%） mentioned ancient books in the recommendations， and only the source of formula name was mentioned in 409 （99.03%） of the publications. ConclusionThe current application of ancient books in TCM clinical practice guidelines and expert consensus is limited， with issues of non-standard searching and evaluation methods. Standar-dization and uniformity are needed in evidence grading and recommendation standards. Future research should clarify the scope and methods of applying ancient book， emphasize their integration with modern research evidence， and enhance their value and quality in the development of TCM clinical practice guidelines.

Objective: To investigate the present situation of health education on school myopia prevention and control in primary and middle schools in Beijing, so as to provide scientific basis and suggestions for effective implementation of health education on school myopia prevention and control. Methods: From November 6-17, 2023, a total of 551 school doctors and health care teachers from public primary and secondary schools in seven districts of Beijing were investigated by using stratified random cluster sampling method. The contents included basic information, the basic situation of school health work, and the status of myopia prevention and control in schools. The data was described by frequency and proportion. Chisquare test was used to analyze the influencing factors. Results: A total of 89.8% of the respondents were found in the school of offering health education courses about myopia prevention and control. Among these respondents, 54.5% were equipped with health education course material of professional myopia prevention and control, and the teachers were primarily class teachers (57.6%), health care teachers (45.5%), and physical education teachers (45.1%), and most of the classes were conducted once a month (33.7%) and once a semester (28.1%). A total of 95.6% of the subjects had health education activities about myopia prevention and control at their schools. The frequency of activities was once a month (38.5%) and once a semester (27.9%). There were statistically significant differences of the report rate in setting up health education courses on myopia prevention and control, and the frequency of activities in different areas and different types of schools (χ2=19.53, 13.15, 34.30, 20.32, P<0.05). Conclusions Health education on school myopia prevention and control in primary and middle schools in Beijing is supportive. But health education courses taught by professional teachers should pay attention to the norms of the course material to complete a certain amount of class time, and development of health education activities should be diversified, so as to effectively implement health education of myopia prevention and control at school.

Circular RNAs (circRNAs) are a new class of non-coding RNAs, which have been confirmed to regulate insect gene expression and immune response through multiple manners such as competing endogenous RNA (ceRNA) regulatory network. Currently, function of circRNA in honey bee immune response remains unclear. In this study, PCR and Sanger sequencing were performed to validate the back splicing (BS) site of ame_circ_000115 (in short ac115). RT-qPCR was used to detect the expression profile of ac115 in larval guts of Apis mellifera ligustica stressed by Ascosphaera apis. Dual-luciferase reporter gene assay was conducted to verify the binding relationship between ac115 and ame-miR-13b. Interference of ac115 in larval guts was carried out by feeding specific siRNA, followed by determination of the effect of ac115 interference on expression of six genes relevant to host immune response. The results confirmed the existence of BS site within ac115. Compared with the un-inoculated group, the expression of ac115 in 4-day-old larval gut of the A. apis-inoculated group was up-regulated with extreme significance (P < 0.000 1), while that in 5- and 6-day-old larval guts were significantly up-regulated (P < 0.05). The brightness of specific band for ac115 in 4-, 5- and 6-day-old larval guts of the siRNA-circ_000115-fed group gradually became weak, whereas that of the siRNA-scrambl-fed group was pretty high without obvious variation. Compared with that of the siRNA-scramble-fed group, the expression of ac115 in 4-day-old larval gut of the siRNA-circ_000115-fed group was significantly down-regulated (P < 0.05), whereas that of the 5- and 6-day-old larval guts were down-regulated with extreme significance (P < 0.001). Ame-miR-13b was truly existed and expressed in A. m. ligustica larval guts, and there was true binding relationship between ac115 and ame-miR-13b. Compared with that of the siRNA-scramble-fed group, the expression of antimicrobial peptide genes hymenoptaecin and abaecin in 6-day-old larval gut of the siRNA-circ_000115-fed group was significantly up-regulated (P < 0.05), while that of ecdysone receptor (Ecr) was down-regulated with extreme significance (P < 0.01). These results indicate that ac115 is truly expressed in A. m. ligustica larval guts, BS site truly exists within ac115, and effective interference of ac115 in A. m. ligustica larval guts can be achieved via feeding siRNA. Moreover, ac115 potentially regulates Ecr expression through adsorption of ame-miR-13b and expression of hymenoptaecin and abaecin using a non-ceRNA manner, further participating in host stress-response.

Chest trauma is one of the most common injuries. Venous thromboembolism (VTE) as a common complication of chest trauma seriously affects the quality of patients′ life and even leads to death. Although there are some consensus and guidelines on the prevention and treatment of VTE at home and abroad, the current literatures lack specificity considering the diagnosis, treatment and prevention of VTE in patients with chest trauma have their own characteristics, especially for those with blunt trauma. Accordingly, China Chest Injury Research Society and editorial board of Chinese Journal of Traumatology organized relevant domestic experts to jointly formulate the Chinese expert consensus on the diagnosis, treatment and prevention of chest trauma venous thromboembolism associated with chest trauma (2022 version). This consensus provides expert recommendations of different levels as academic guidance in terms of the characteristics, clinical manifestations, risk assessment, diagnosis, treatment, and prevention of chest trauma-related VTE, so as to offer a reference for clinical application.

Objective    To compare the clinical outcomes of transcatheter aortic valve implantation (TAVI) in oncology and non-oncology patients with severe aortic stenosis (AS). Methods    A computer-based search in PubMed, The Cochrane Library, EMbase, CBM, CNKI and Wanfang databases from their date of inception to December 2021 was performed, together with reference screening, to identify eligible clinical trials. Two investigators screened the articles, extracted data, and evaluated quality independently. RevMan 5.3 and Stata 12.0 softwares were used for meta-analysis. Results    The selected 8 cohort studies contained 57 988 patients, including 12 335 cancer patients and 45 653 non-cancer patients. The results of meta-analysis showed that in patients with cancer, the 30-day mortality [OR=0.74, 95%CI (0.65, 0.84), I2=0%, P<0.000 01], stroke [OR=0.87, 95%CI (0.76, 0.99), I2=0%, P=0.04] and acute kidney injury [OR=0.81, 95%CI (0.76, 0.85), I2=49%, P<0.000 01] were lower than those in patients without cancer. The 1-year mortality [OR=1.46, 95%CI (1.15, 1.86), I2=62%, P=0.002] and late mortality [OR=1.51, 95%CI (1.24, 1.85), I2=61%, P<0.000 1] were higher in patients with cancer. Conclusion    It is effective and safe in cancer patients with severe AS undergoing TAVI. However, compared with patients without cancer, it is still high in long-term mortality, and further study of the role of TAVI in cancer patients with AS is necessary.

Basophils have been neglected for a long time as an immune cell.Recently, it gained respect because of its important role in helper T lymphocytes(Th)2 immune response.Basophils are involved in the pathogenesis of bronchial asthma through a variety of possible mechanisms.Basophils can act as initiators initiate and establish Th2 immune response by interacting with dendritic cells; basophils can act as immune regulators, regulate immune cell functions such as type 2 innate lymphoid cells by secreting cytokines such as interleukin 4 to consolidate allergic inflammation; basophils can also act as immune effectors participate in allergic airway inflammation through IgE-depended and non IgE-depended activation.In addition, clinical research is focused on the usage of basophil activation status as possible biomarker in predicting the outcome of allergic disease therapy, which is of great clinic value in individualized management of asthma.

OBJECTIVE:To compare the differences between artificially cultivated and wild Xinjiang Artemisia rupestris,and screen the different components. METHODS:HPLC-MS was adopted to establish the fingerprints of artificially cultivated and wild Xinjiang A. rupestris from different origin and harvest time. Principal component analysis was conducted by Marker ViewTM soft-ware and SIMCA-P 11.5 software,the characteristics of principal components were analyzed,difference variable was screened, and different components of artificially cultivated and wild varieties were obtained. RESULTS:Fingerprints of 22 batches of A. rup-estris(12 batches of wild varieties,10 batches of artificially cultivated varieties)were established. According to the principal com-ponent analysis,artificially cultivated and wild varieties were well grouped,with obvious differences;the principal components of artificially cultivated varieties with different harvest time showed certain difference,mainly before and after flowering,concentrat-ing in to-be flowering and full flowering periods. Wild varieties from different origins had obvious regional difference,showing cer-tain differences in composition and content. 268 variables were found in matrix of positive ion mode and 155 in negative ion mode. 28 groups of variables were extracted by difference variable,and 19 variables were determined. CONCLUSIONS:Artificially culti-vated and wild varieties have obvious difference in principal component,mainly in flowering period and picking places. It can pro-vide theoretical basis for the standardized cultivation and origin protection of Xinjiang A. rupestris.
