Objective To explore the traumatic situation and transfer methods of the in-patients injured in Lushan Earthquake, and to provide evidence for treating injured mass in future. Methods The information of the patients injured in Lushan Earthquake who were admitted in Chengdu Military General Hospital were collected by “No. 1 Military Medical Project” hospital information system and a self-edited “Questionnaire for Hospitalized Patients Injured in 4.20 Lushan Earthquake”. Results A total of 65 patients were admitted in this hospital: 63 (96.92%) patients were injured in the main shock; 28 (43.08%) patients were injured by building collapse; 23 (35.38%) patients got injured due to falls or got bruised when escaping; and 14 (21.54%) patients were accidentally injured. Rescue methods: 32 (49.23%) patients were saved by themselves; 23 (35.38%) patients were mutually helped; 10 (15.38%) patients were rescued by local non-military rescue team; 34 (52.31%) patients were rescued by military rescue teams; and 26 (44.83%) patients were transferred by air transport. Conclusion In order to cope with emergencies and major disasters (e.g. earthquake) and to treat injured mass scientifically in the future, we should set up emergency wards scientifically and reasonably, carry out education on earthquake prevention and disaster mitigation widely, reinforce self-care and mutual aid in the stricken area, quickly send rescue and medical teams, and organize training for air transportation of patients.
Objective To investigate the psychological stress level and its influence factors of the motor transport soldiers in Military Station C at high altitude, and provide the data basis for the proper stress management. Methods A cluster random sampling was performed on the motor transport soldiers in Military Station C. And SCL-90 were adopted to measure the psychological stress level of the motor transport soldiers while the self-made basic information questionnaire was conducted to collect the information of demographic characteristic, length of military service, driving years. Then the effect of basic information on the psychological stress level was analyzed. Results 1 692 soldiers in Military Station C were enrolled in this survey. The scores of somatization, depression, psychosis and the total score of the SCL-90 of these soldiers were higher than the norm (allP values<0.001). The scores of interpersonal relationship, depression, terror and stubborn of the only child were higher than those of non-only-child (P=0.034,P=0.039,P=0.025,P=0.002). The scores of interpersonal relationship and anxiety were positively correlated with their education levels (P=0.008,P=0.026). The compulsory servicemen had higher scores of anxiety, terror and psychosis (P<0.001,P=0.026,P=0.001) but lower scores of somatization (P<0.001) compared with the sergeants. Those who suffered from neck discomfort had higher somatization scores (P<0.001). Conclusion Some factors involved in psychological stress level of the motor transport soldiers in Military Station C are higher than the norm, suggesting that more attention should be paid to their psychological states by the army administrators and the health management department, especially the only child, new recruits, junior soldiers and those who suffers from somatization discomfort.
Objective To systematically review the prevalence of depression in rural Chinese population aged 60 and above from 2010 to 2023. MethodsThe CNKI、WanFang Data、VIP、CBM、PubMed、Embase and Cochrane Library databases were electronically searched to collect cross-sectional studies on the prevalence of depression of elderly populations in rural China from January 2010 to March 2023. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using Stata 17.0 software. ResultsA total of 23 cross-sectional studies with a total sample of 34 916 cases and 11 308 depression patients were included. The meta-analysis results showed that the prevalence of depression in rural Chinese population was 31.02% (95%CI 26.10% to 36.16%). Subgroup analysis showed that the prevalence was higher among females than males; the GDS-30 scale had the highest detection rate, followed by the CES-D-10 and GDS-15 scales; the prevalence was higher in the Midwest than in the East; and the prevalence was higher in surveys conducted after 2015 than in 2015 and before. In addition, the prevalence of depression was higher in the rural elderly population aged 70 and above, non-married, illiterate or semi-literate, with poor self-rated health status, living alone, in poor economic status, with chronic diseases, and with low social activity. ConclusionThe prevalence of depression is high among the rural elderly population in China, and there are significant disparities in the prevalence of different characteristics of the elderly. These differences should be given more attention to improve the mental health of the rural elderly population. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Objective To explore the number variation trend of inpatients with traumatic brain injury (TBI) in high altitude and plain areas. Methods The first page information in medical records of TBI patients, who were admitted to military hospitals from 2001 to 2007, was searched and extracted from the Chinese Trauma Database. Two military hospitals in high altitude area and another two in the same hospital level in plain area were selected. Then, the number variation trend of TBI inpatients in those two areas was compared. Results In high altitude area, the proportion of male patients and their median inpatient days were higher, while the age, proportion of Han patients and surgery rate were lower than those in plain area (all Plt;0.001). During 2001-2007, there were 9 141 TBI patients discharged from the four hospitals, and the average annual growth rate was 13.15%. In high altitude area, the average annual growth rate of discharged inpatients was 24.00%, while in plain area, it was just 7.09%. The 4 common categories of TBI were intracranial injury, open wound of the head, neck and trunk, skull fracture, and other injuries. Conclusion Compared with the plain area, there are significant differences in the demographics, hospital stay and surgery of inpatients in high altitude area. The average annual growth rate of TBI inpatients discharged from hospitals in high altitude area is faster than that in plain area, to which should be paid attention by relevant departments.
目的 初步观察电针足三里穴对不全肠梗阻大鼠小肠Cajal间质细胞（interstitial cells of Cajal，ICC）数量变化的影响，为进一步探讨电针足三里穴对ICC表型变化的影响奠定基础。方法 采用圈套法造成不全肠梗阻从而建立ICC数目减少的SD大鼠模型。取20只雌性大鼠采用简单随机法均分成正常对照组、不全肠梗阻30d未电针足三里穴组（梗阻组）、不全肠梗组30d电针足三里穴组（足三里组）和不全肠梗阻30d电针阴陵泉穴组（阴陵泉组） 4组。其中足三里组和阴陵泉组分别连续电针足三里穴或阴陵泉穴7d后，取小肠组织采用免疫组化方法以及免疫荧光观察ICC数量的变化。结果 正常对照组、足三里组、梗阻组及阴陵泉组ICC阳性面积分别为（102 051.00±16 969.38） μm2、（92 642.12±14 854.49） μm2、（45 221.33±6 230.20） μm2和（63 136.16±8 863.91） μm2，各组间差异有统计学意义（F=21.240，P＜0.001），其中足三里组的ICC阳性面积较梗阻组高（P＜0.05）。结论 电针足三里穴可使不全肠梗阻大鼠小肠受损的ICC数量得到部分恢复，但其具体机理有待进一步研究。
