Ethical review represents the core of the scientific and technological ethical governance， and its quality depends on the participation of ethics. The absence of ethics and ethical experts will compromise the quality of the review. According to the spirit of the Guidelines on Strengthening the Governance over Ethics in Science and Technology， this paper analyzed the process of separating scientific and technological ethics from the field of scientific research morality， clarified the ethical attributes of ethical review， and argued that scientific research and technological innovation activities originated from ethics. On this basis， the fundamental principle of “ethics first” was proposed， aiming to proactively embed ethical considerations throughout the entire process of scientific and technological activities. This principle was the primary requirement for ensuring governance effectiveness and can also eliminate the risk of ethics being obscured in ethical governance. In practice， “ethics first” manifested specifically in dimensions such as prioritizing academic systems， prioritizing publicity， education， and training， as well as further advancing ethical considerations.

The Occupational Classification Dictionary of the People's Republic of China (2015 Edition) has added a new occupation type, Medical Nursing Assistants, aiming to meet the strong demand for medical care in the context of the aging population in China.In order to standardize the services of medical nursing assistants for the elderly in home and community settings and contribute to healthy aging, the National Health Commission issued the " Service Standards for Medical Nursing Assistants of Older Adults in Home and Community" ( WS/ T 803—2022) on September 28, 2022.The standards regulate the service processes, service items and requirements, as well as service evaluation and improvement for elderly medical nursing assistants.The interpretation of the standard's formulation background, the compilation process, and the standard's content are as follows.

Objective:To investigate the imaging characteristics of clear cell acanthoma (CCA) by dermoscopy and reflectance confocal microscopy (RCM) .Methods:A retrospective analysis was conducted on 12 patients diagnosed with CCA through histopathological examination at the Department of Dermatology, Wuhan No.1 Hospital, from 2020 to 2024. Dermoscopic and RCM features of these cases were summarized.Results:Among the 12 CCA patients, 3 were males and 9 were females, and they were aged 50.08 ± 10.43 years. Clinically, CCA lesions were typically presented as red or brown papules or nodules with well-defined borders, ranging in diameter from 3 mm to 2 cm. Histopathological examination showed that the tumor manifested as psoriasiform or papillary hyperplasia with a thickened spinous layer and a distinct boundary surrounded by the normal skin; proliferating cells were larger with lightly stained cytoplasm; neutrophil infiltration was observed in the epidermis, and vascular dilation was observed in the dermal papillae and superficial dermis; periodic acid-Schiff staining revealed abundant glycogen in the cells. In 10 patients examined by dermoscopy, dotted, globular, or glomerular vessels were arranged in a beaded pattern in all the 10 patients, and collar-like scales were seen at the edges of the lesions in 6 patients. In 6 patients examined by RCM, RCM images all revealed epidermal hyperplasia, thickened spinous layers, large keratinocytes with enlarged nuclei and abundant cytoplasm that blended in with the intercellular demarcations, disordered honeycomb structure of the epidermis, and dilation and up-thrust of blood vessels in the dermal papillae and superficial dermis; segmented cell infiltration was observed in the epidermis of 4 patients. As measured, the longest diameters of cells in the upper part of the CCA spinous layer ranged from 30.25 μm to 35.13 μm; the longest diameters of spinous layer cells at the CCA follicles (19.39 ± 2.93 μm) were significantly lower than those of the surrounding spinous layer cells (30.95 ± 5.66 μm, t = 5.73, P < 0.001) . Conclusions:CCA presents a distinctive vascular pattern on dermoscopy, and the majority of histological features can be visualized by RCM. Dermoscopy and RCM can be relatively reliable auxiliary diagnostic methods for CCA.

Objective:To describe epidemiological characteristics and their influencing factors of diabetes and pre-diabetes among adult residents in Hainan Province and provide a theoretical basis to develop epidemic prevention and control strategies for diabetes.Methods:This study used a two-stage unequal proportion cluster sampling method, and 32 857 subjects (≥18 years old) were collected from 24 cities/counties/districts in Hainan Province. All the subjects were investigated with questionnaires, physical examination, and laboratory tests from January to June 2023. The χ2 and Mantel-Haenszel trend χ2 tests were used to analyze the data. Multivariate logistic regression was used to analyze the factors influencing diabetes and pre-diabetes. SPSS 23.0 software was used to analyze the data. Results:The crude prevalence of diabetes and pre-diabetes in adult residents of Hainan Province were 18.1% and 22.8%, while the weighted rates were 13.7% and 20.7%, respectively. The results of multivariate logistic regression analysis showed that: aging (30-39 years old: OR=2.65, 95% CI: 2.06-3.41; 40-49 years old: OR=5.64, 95% CI: 4.40-7.24; 50- 59 years old: OR=9.88, 95% CI: 7.71-12.67; 60-69 years old: OR=18.34, 95% CI: 14.28-23.55; 70-79 years old: OR=21.30, 95% CI: 16.41-27.65; 80 years old and above: OR=24.13, 95% CI: 17.94-32.46), nationality (Li minority group: OR=1.50, 95% CI: 1.38-1.63; other ethnic groups: OR=1.53, 95% CI: 1.20-1.94), urban ( OR=1.12, 95% CI: 1.04-1.21), central obesity ( OR=2.14, 95% CI: 2.01-2.29), higher frequency of alcohol consumption (5-7 day/week: OR=1.24, 95% CI: 1.11-1.38), physical inactivity ( OR=1.09, 95% CI: 1.02-1.17) were risk factors for diabetes, while aging (30-39 years old: OR=1.53, 95% CI: 1.31-1.79; 40-49 years old: OR=2.36, 95% CI: 2.01-2.76; 50-59 years old: OR=3.03, 95% CI: 2.58-3.55; 60-69 years old: OR=4.22, 95% CI: 3.58-4.97; 70-79 years old: OR=5.05, 95% CI: 4.23-6.04; 80 years old and above: OR=6.08, 95% CI: 4.86-7.61), nationality: (Li minority group: OR=1.18, 95% CI: 1.10-1.28; other ethnic groups: OR=1.40, 95% CI: 1.14-1.71), urban ( OR=1.12, 95% CI: 1.04-1.19), central obesity ( OR=1.72, 95% CI: 1.62-1.83), higher frequency of alcohol consumption (1-4 day/week: OR=1.12, 95% CI: 1.01-1.23; 5-7 day/week: OR=1.35, 95% CI: 1.22-1.49) were risk factors for pre-diabetes. Conclusions:The epidemic situation of diabetes and pre-diabetes among adult residents in Hainan Province was not optimistic. In order to control the development of abnormal blood glucose, measures and targeted health education should be carried out to strengthen the screening, treatment, and management of people with abnormal blood glucose among different populations.

Background:To compare the efficacy and safety of monthly administrations of gonadotropin releasing hormone (GnRH) agonists LY01005 and Zoladex ? in Chinese patients with premenopausal breast cancer. Methods:From October 2020 to November 2021, 188 premenopausal breast cancer patients were enrolled in 34 hospitals and randomized 1:1 to receive either LY01005 or Zoladex ? every 28 days for a total of three injections. All patients concomitantly received oral tamoxifen (TAM). The primary efficacy endpoint was cumulative probability of maintaining menopausal level [oestradiol (E2) ≤30 pg/ml] from day 29 to day 85. The second efficacy endpoint included changes in E2, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) compared with the baseline. Pharmacokinetics (PK), pharmacodynamics (PD), and safety were analyzed. The study also evaluated the pharmacokinetic and pharmacodynamic characteristics of LY01005. Results:A total of 188 patients were randomised and 187 patients received either LY01005 or Zoladex ?. Cumulative probabilities of maintaining menopausal level (E2≤30 pg/ml) from day 29 to day 85 were 93.1% for LY01005 and 86.3% for Zoladex ?. The between-group difference was 6.8% (95% CI: -2.3%, 15.9%) and primary efficacy in the LY01005 group was not inferior to that in the Zoladex ? group. Changes in E2, LH, and FSH levels compared with the baseline were equivalent between the two groups (E2: 89.34% to 90.23% vs. 82.11% to 85.02%; LH: 88.89% to 95.52% vs. 89.70% to 97.02%; FSH: 75.36% to 80.85% vs.73.07% to 80.24%, respectively). After three consecutive doses of LY01005, the LH and FSH levels of the subjects showed a transient increase after the first dose, reached a peak on the second day and then started to decrease. The LH and FSH reached a lower level and remained at or below that level until the 85th day. Both treatments were well-tolerated. Conclusion:LY01005 is as effective as Zoladex ? in suppressing E2 to menopausal levels in Chinese patients with premenopausal breast cancer, with a similar safety profile.

Objective:To explore the effect of inspiratory muscle training(IMT)on respiratory function,psychological well-being,and sleep in patients recovered from corona virus disease 2019(COVID-19)infection.Method:Seventy-six adults who had recovered from COVID-19 between February and June 2023 at the depart-ment of rehabilitation medicine of the fourth medical center of the PLA general hospital,with a massive inspi-ratory pressure(MIP)of less than 70%were selected for this study.The participants were randomly divided into the control group(n=38)and the experimental group(n=38).The control group received conventional re-habilitation training,while the experimental group underwent an additional 4-week IMT program on top of con-ventional rehabilitation.Respiratory function including maximum massive inspiratory pressure(MIP),forced expi-ratory vital capacity(FVC),forced expiratory volume in the first second(FEV1),forced expiratory volume/forced vital capacity in the first second(FEV1/FVC),and peak expiratory flow rate(PEF),were measured be-fore and after the 4-week intervention.Psychological status and sleep quality were assessed using the Hamilton depression scale(HAMD),the Hamilton anxiety scale(HAMA)and Pittsburgh sleep quality index(PSQI).Result:After 4 weeks of intervention,the MIP,FVC,FEV1,FEV1/FVC,HAMD,HAMA,and PSQI im-proved in both control and experimental group compared with pre-intervention.The MIP,PEF,and PSQI in the experimental group were significantly better than pre-intervention(P<0.05);the control group showed sig-nificant improvement in MIP,FVC,FEV1,HAMA,and PSQI compared to pre-intervention(P<0.05).After 4 weeks of intervention,the MIP and PEF in the experimental group were significantly better than those in the control group(P<0.05);there was no significant difference in FVC,FEV1,FEV1/FVC,HAMD,HAMA,and PSQI between the two groups(P>0.05).Conclusion:IMT can effectively improve the respiratory function,physical and mental health of patients recov-ered from COVID-19,making it an effective rehabilitation strategy for post-COVID-19 recovery.

Objective To investigate the incidence of hip fracture among the elderly in communities,explore related influencing factors,and develop and validate a risk prediction model.Methods A stratified sampling method was used to collect sociodemographic data,lifestyles and risk factors in hip fracture between January 2023 and January 2024 among the elderly residents in communities in Deyang.With random splitting,479 elderly people(68.00%)were assigned to the model training set,and 221(32.00%)to the model validation set.In the model training set,the participants were divided into a fracture group and a non-fracture group based on hip fracture or not.Data from both groups were compared,and R software(version 4.3.1)was employed to develop and validate the risk prediction model.Results A total of 700 elderly residents in communities were included,62 of them had hip fracture within one year yielding a cumulative incidence rate of 8.86%.The risk prediction model identified six predictors:frequent consumption of preserved foods,daily exercise time,daily sunlight exposure,osteoporosis,times of fall within a year,and with≥20 pieces of natural teeth.In the training set,the model achieved an AUC of 0.945(95%CI:0.908-0.982),with a sensitivity of 88.89%and a specificity of 89.40%.The calibration curve demonstrated a good agreement between predicted and actual values,indicating a strong calibration.Decision curve analysis(DCA)showed a positive net benefit.In the validation set,the AUC was 0.892(95%CI:0.784-0.999),with a sensitivity of 82.35%and a specificity of 93.63%,confirming a good model fit and predictive performance.The calibration curve exhibited a strong consistency,and DCA indicated a positive net benefit.Conclusion The developed risk prediction model for hip fracture in elderly community residents demonstrates a strong predictive value.It provides a practical reference for community workers and healthcare professionals to screen and assess the risk of hip fracture among the elderly residents in communities.
