Objective To investigate the occurrence circumstance of acute stress disorder(ASD),clinical features and related risk factors,in the officers and soldiers who had gone to Beichuan county to provide disaster relief.Methods We used the self-general questionnaire,post-traumatic stress symptoms self-rating scale(PCL-C),perceived social support scale(PSSS),and coping style questionnaires(SCSQ)to assess the 126 subjects,combining with semi-structured interviews to determine and compare the ASD group and control group,and then analyzed the related factors.Results The prevalence rate of ASD officers and soldiers was 13.49%,with main symptoms of repeatedly breaking into painful memories,nightmares,reproducing the scenes of traumatic events,strong trouble of psychological pain,decreased interest,sleep disorders and emotional instability.These main symptoms of ASD interacts each other,and were reduced with positive response and good social support.Conclusion In the phase of acute stress(one month),the officers and soldiers taking part in earthquake relief have symptoms of ASD,so we should strengthen the necessary psychological assessment and comprehensive psychological intervention means,in order to slow down psychological trauma after disaster,prevent and reduce the possibility that ASD turns into post-traumatic stress disorder(PTSD).

Objective Animal experiment is indispensible for the progress of medicine and medical research.Experimental animals deserve basic respect and care.This paper reviewed the history and status of the experimental animal welfare nationally and internationally to identify the ethical problems existed in animal experiments,and finally discuss the establishing of ethical review system of experimental animals.Methods According to literature review,as well as summarizing the operating practice in the affiliated hospital of Chengdu university of TCM,this study analyzed the problems in the field of experimental animal welfare protection.Results Many countries,such as Britain,Germany and the United States,have legislation on the welfare of experimental animals.There are no such laws in China while departmental regulations has formulated.At present,the weak cognition of bioethics among medical personnel,lack of corresponding certification system,lack of the ethical review system of laboratory animal are still unsolved problems.This paper summarizes the principles of ethical review,the documents of review and the elements of review.Conclusions The protection of experimental animals is a systematic project,and ethical review as the first link of animal experiments can play a good role in promoting animal experiment.

Objective:To study the effect of health management based on the transtheoretical model and stages of change on patients with diabetes mellitus complicated by obesity.Methods:A total of 122 patients with type 2 diabetes mellitus (T2DM) complicated by obesity and admitted to Guangdong Second Provincial General Hospital between January 2019 and June 2020 were recruited to participate in the study. They were divided into two equal groups at random, the observation group and the control group —with 61 patients in each group. Both groups were subjected to individualized health management based on conventional drug treatment. The control group received routine health education and psychological support, while the observation group was subjected to the transtheoretical model and stages of change interventions for six months. The independent-samples t-test was used to compare blood glucose, body weight, and self-efficacy in the two groups after interventions, and the χ 2 test or Fisher′s precise test was used to compare behavior habit compliance rates in the two groups after interventions. Results:FBG with (6.27±0.92) mmol/L and (6.58±0.91) mmol/L, 2hPG with (8.53±1.39) mmol/L and (8.53±1.39) mmol/L, and HbA1c with (6.49±0.91)% and (6.78±0.96)% in the two groups were significantly lower at six months of interventions than those before ( P<0.05), but the differences between the two groups were not statistically significant ( P>0.05). BMI, waist circumference, and body fat rate with (30.46±2.51) kg/m 2, (91.72±10.45) cm, and (34.09±3.84)% of the observation group at six months of interventions were significantly lower than those before interventions ( P<0.05), whereas there were no significant changes in the control group before and after interventions ( P>0.05). The observation group′s BMI and body fat rate were lower than those of the control group ( P<0.05). The General Self-Efficacy Scale (GSES) scores in the two groups were (31.62±2.59) points and (28.75±2.48) points, which were significantly higher than those before interventions ( P<0.05). The observation group′s GSES score was higher than that of the control group ( P<0.05). At six months of interventions, the compliance rates of diet control (92.98% and 77.97%), reasonable exercise (87.72% and 71.19%), adherence to medication (98.25% and 91.53%), quitting smoking and alcohol (94.74% and 81.36%), blood glucose monitoring (91.23% and 94.92%), and regular review (100.00% and 98.31%) were all significantly higher in the two groups than those before interventions ( P<0.05). Additionally, the compliance rates of diet control, reasonable exercise, and quitting smoking and alcohol in the observation group were higher than those of the control group ( P<0.05). Conclusion:The use of the transtheoretical model and stages of change for the self-management intervention of diabetes mellitus patients with obesity is beneficial to improve self-efficacy, behavioral habits, and weight control effectiveness.

Objective:To investigate the correlation between residual cholesterol (RC) and carotid intima-media thickness (cIMT) in non-diabetic population.Methods:Non-diabetes population received health examination in Nanjing Drum Tower Hospital, The Affiliated Hospital of Nanjing University Medical School from January 1, 2018 to December 31, 2021 were retrospectively included. According to the carotid ultrasound results, they were divided into cIMT thickening group (≥1 mm) and non-thickening group (<1 mm). The RC level was calculated according to total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C). Multivariate logistic regression analysis was used to determine the correlation between RC and cIMT. Results:A total of 1 803 non-diabetes subjects, aged 58.3±15.6 years, including 1 100 males (61.0%), were enrolled. There were 916 patients (50.8%) in the cIMT thickening group and 887 (49.2%) in the non-cIMT thickening group. Compared with the non-cIMT thickening group, cIMT thickening group had significantly higher proportion of male, hypertension, hyperlipidemia, atrial fibrillation, past stroke history, smoking and alcohol consumption, as well as significantly higher age, blood glucose, triglyceride, RC, TC and LDL-C, and significantly lower HDL-C (all P<0.01). Multivariate logistic regression analysis showed that RC was independently associated with cIMT thickening ( Ptrend<0.001). Conclusion:RC is associated with cIMT thickening in non-diabetes population.
