Objective To evaluate the maternal age at delivery in Beijing and the effect of maternal age on pregnancy outcomes.Methods A retrospective analysis was conducted on 14 970 singleton pregnancies from 15 hospitals in Beijing from June 20th to November 30th in 2013.These hospitals were sorted by the numbers of delivery and chosen as clusters by systemic cluster sampling method.The data of age,diagnosis with gestational diabetes mellitus (GDM) and pre-eclampsia (PE),neonatal birth weight,gestational age at delivery,postpartum hemorrhage and infants admitted to the neonatal ICU (NICU) were collected.The 14 970 women were divided into 5 groups according to their ages at delivery:(1) less than 20 years (n=205),(2)20-<30 years (n=9 228),(3)30-<35 years (n=4 365),(4)35-<40 years (n=1 017),and (5) 40 years and older (n=155).T-test and x2 test were used for between-group comparison,and logistic regression analysis was used to examine the association between age and the risk of adverse pregnancy outcomes.Results (1) The mean maternal age at delivery in 2013 in Beijing was (28±4) years old.Among them,205 (1.4%,205/14 970) delivered under 20 years of age;1 172 (7.8%,1 172/14 970) ≥35 years;and 155 (1.O%,155/14 970) at 40 years and older.(2) The prevalence of diabetes,hypertension,overweight and obesity increased with age,and the incidence of these conditions were 3.4%,4.3% and 31.4% in women with advanced age,respectively.(3) Compared with 20-<30 years group,less than 20 years was associated with significantly lower incidence of GDM [adjust OR (aOR)=0.393,95% CI:0.222-0.696] and cesarean section rate (aOR=0.549,95%CI:0.391-0.771),and higher incidence of preterm birth (aOR=2.144,95%CI:1.256-3.662).Moreover,30-<35 years,35-<40 years and 40 years and older groups all had significantly higher risk of GDM (30-34 years,aOR=1.513,95%CI:1.374-1.666;35-<40 years,aOR=2.094,95%CI:1.786-2.455;≥40 years,aOR=2.174,95%CI:1.492-3.167),preterm birth (aOR=1.219,95%CI:1.021-1.455;aOR=1.644,95%CI:1.251-2.161;aOR=2.141,95%CI:1.209-3.792),cesarean section (aOR=1.373,95% CI:1.268-1.486;aOR=2.960,95% CI:2.550-3.435;aOR=4.332,95%CI:2.920-6.426) and NICU admission rate (aOR=1.236,95%CI:1.059-1.443;aOR=1.337,95%CI:1.018-1.756;aOR=2.389,95%CI:1.385-4.121),when compared to the 20-<30 years of age group.Higher incidence of PE (aOR=1.292,95%CI:1.007-1.659) and postpartum hemorrhage (aOR=1.224,95%CI:1.048-1.429) were also noted in women of 30-<35 years,compared to 20-<30 years group respectively.Conclusion Both advanced maternal age and adolescent pregnancy are associated with increasing risk of adverse pregnancy outcomes.

Objective:To investigatethe transdermal delivery characteristics of methylphenidate hydrochloride (MPH) in vitro. Methods: Characteristics of MPH crossing nude rats skin were studied with Franz diffusion cells. A high performance liquid chromatographic (HPLC) method was established to determine the concentration of MPH crossed the skin. The permeability coefficient (P), steady state flux (J) and lag time(LT) for MPH through the skin of nude rats treated with various enhancers were compared with those of control. Results: The permeability coefficient increased with the increase of MPH concentration. The penetration of MPH through nude rats skin was obviously enhanced by 8%Azone and 5%propylene glycol (P

After the outbreak of coronavirus disease 2019, the number of severe cases in Wuhan increased dramatically, which was far beyond the load of intensive care unit.As a result, the isolation ward became the place for the treatment of severe cases.Because the important role of anesthesiologists, more than 20 anesthesiologists from Union Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology have been sent to eight isolation wards of severe patients.They have participated in the treatment of more than 800 severe coronavirus disease 2019 patients, including more than 300 critical cases with more than 120 cases getting better recovery.Their work included endotracheal intubation, central venous catheterization, artery cannulation and blood gas analysis, and bedside cardiopulmonary ultrasound examination, and more importantly they have played an important role in respiratory management after endotracheal intubation, the treatment of cardiovascular events and precise fluid therapy.During these works, anesthesiologists improved their own professional skills through the cooperation with other specialists, including the standard writing skills of medical records and prescription, appropriate protection against infectious diseases, standard medication and oxygen therapy for respiratory diseases, and the capability of continuously management of critical cases.

It has been proposed by Basic Questions On Proper Therapies for Different Diseases Geographically (《素问·异法方宜论篇》) that "wei (痿) diseases should be treated by Daoyin (导引)". Furthermore, it is clarified that the indications of Daoyin are those conditions related to spleen and dampness caused by dampness pathogen, excessive food intake and less exercise, and mainly manifested as heavy limbs, fatigue and flaccidity, which is similar to the metabolic imbalance in the early stage of glucose or lipid metabolism disorder in modern medicine. Based on modern clinical and basic research evidence, Daoyin can inhibit the response of inflammation, alleviate oxidative stress, regulate intestinal microbiota, and modulate gene expression to improve metabolic abnormalities, and this will provide ideas for researches on the indications of Daoyin.

ObjectiveTo investigate the current status and development needs of evidence-based medicine (EBM) capability in ethnic minority medicine, and explore effective strategies to enhance EBM capability in this field. MethodsThe questionnaire survey was conducted in various ethnic minority medical institutions and research organisations. The questionnaire covered three dimensions, firstly, perceptions and attitudes towards evidence-based medicine; secondly, advantages and challenges in the development of ethnic minority medicine; thirdly, demands and recommendations for enhancing evidence-based medicine capability in ethnic minority medicine. ResultsA total of 501 valid questionnaires were collected, of which 103 questionnaires were collected by re-sending to minority medicine regions with insufficient participation. The questionnaires included 354 responses (70.66%) from practitioners of minority medicine, including Tibetan medicine, Mongolian medicine, Uyghur medicine, Zhuang medicine, and Korean medicine. Among the 501 questionnaires, 146 respondents (29.14%) indicated that they knew about EBM, 355 respondents (70.86%) had either a "general understanding" or had "not heard about" EBM before, and 469 respondents (93.61%) believed that introducing ECM could promote the development of ethnic minority medicine. The primary challenge in promoting EBM in the field of ethnic minority medicine is the lack of professionals in EBM and a lack of understanding of how to apply it into clinical practice (442 respondents, 88.22%). In the 9-point importance rating for enhancing evidence-based abilities, high scores were achieved in standardization of clinical practice guidelines (7.50±1.90) and methods for sample sizes in clinical research (7.45±1.90). Regarding the demand for improving clinical research literacy, expert academic lectures, and experience sharing (404 respondents, 80.64%) and evidence-based methodology monographs on ethnic minority medicine (401 respondents, 80.04%) were emphasized. ConclusionsPractitioners in ethnic minority medicine hold a positive attitude towards integrating EBM. However, there remains substantial room for the education and dissemination of EBM. Enhancing evidence-based capabilities can be achieved through specific measures such as cultivating or recruiting talents in EBM, establishing evidence-based support platforms for clinical research, organizing regular academic lectures and exchanges, and strengthening the construction of theoretical frameworks and evaluation systems tailored to ethnic minority medicine, thereby following a path of evidence-based practices aligned with the unique characteristics of ethnic minority medicine.
