ObjectiveTo study preoperative diagnosis and operative route of traumatic diaphragmatic rupture in order to improve postoperative quality of patients' life.MethodsA retrospective analysis was carried out in 63 patients with traumatic diaphragmatic rupture,all that were identified through operation from January 1990 to March 2009.All cases were associated with pneumothorax and/or hemopneumothorax at various degrees.Forty-nine cases complicated with acute peritonitis and 41 cases complicated with hemorrhagic shock.Thirty-seven cases were diagnosed definitely preoperatively,22 cases were found in operations research,4 cases with inefficacious conservation converted to operation.Thoracotomy was performedin 24 cases,laparotomy in 14 cases,combined thoracolaparotomy in 8 cases and thoracotomy plus laparotomy in 17 cases.ResultsFifty-seven cases recovered,6 cases died of hemorrhagic shock (2 cases),pericardial tamponade ( 1 case),acute respiratory failure ( 1 case) and acute renal failure at postoperative 1 week (2 cases).ConclusionDefinite and timely preoperative diagnosis and correct operative approach are striving the rescue time and success and avoiding complication.

Objective To explore the influence of different method of mediastinal lymph node excision on the immune function of non-small cell lung cancer patients.Metbods Clinical data was collected continuously from 415 cases of inhospital patients with non-small cell lung cancer from March 2009 to March 2012,who were divided into system lymph node dissection group (SLND,216 cases) and lymph node sampling group (LNS,199 cases).The total lymphocytes,NK cells,CD4+ T cells and CD8+ T cells in blood samples taken preoperatively and at 3rd and 7th day postoperation were analyzed.Results Total lymphocytes,NK cells and CD8+ T cells were reduced significantly in the SLND group compared with those in LNS group at 3rd day and 7th day postoperation (3rd day:LC (0.95±0.57) × 109/L vs (1.10±0.65) × 109/L,CD8+ T cells (19.53± 6.48) ％ vs (20.93±6.70) ％,NK (17.36±6.06) ％ vs (18.57±5.97) ％,P ＜ 0.05; 7th day:LC (0.86±0.53) × 109/L vs (1.00±0.60) × 109/L,CD8+ T cells (17.27±5.64) ％ vs (18.40±5.26) ％,NK (13.11±4.84) ％ vs (14.20± 5.30) ％; P ＜ 0.05).CD4+ T cells in the SLND group were reduced significantly at 3rd day postoperation compared with LNS group ((29.59±6.53) ％ vs (31.19±6.32) ％,P ＜ 0.05).Conclusion LNS can reduce immunosuppression compared with SLND for postoperative patients.

Objective:To investigate the distribution characteristics of cognition-related lifestyles of elderly in communities and explore the integrated effects on early cognitive decline.Methods:The participants were from the Project of Prevention and Intervention of Neurodegenerative Disease for Elderly in China. A total of 2 537 older adults aged ≥60 years without dementia in the 2015 baseline survey and the 2017 follow-up survey were included. The information about their cognition-related lifestyles, including physical exercise, social interaction, leisure activity, sleep quality, smoking status, and alcohol consumption, were collected through questionnaire survey and the integrated scores were calculated. Multivariate logistic regression analysis was used to assess the association between integrated cognition-related lifestyle score and early cognitive decline.Results:In the 2 537 older adults surveyed, 28.7% had score of 5-6, while only 4.8% had high scores for all 6 healthy lifestyles. Significant differences in healthy lifestyle factor distributions were observed between men and women. Multivariate logistic regression model showed that the risks for early cognitive decline in the older adults who had lifestyle score of 4 and 5-6 were lower than that in those with lifestyle score of 0-3 ( OR=0.683, 95% CI: 0.457-1.019; OR=0.623, 95% CI: 0.398-0.976; trend P=0.030). In the women, the risks for early cognitive decline was lower in groups with score of 4 and 5-6 than in group with score of 0-3 ( OR=0.491, 95% CI: 0.297-0.812; OR=0.556, 95% CI: 0.332-0.929; trend P=0.024). Conclusion:Cognition-related healthy lifestyles are associated with significantly lower risk for early cognitive decline in the elderly, especially in women.
