Objective To investigate the relationship between serum interleukin 6( IL-6 ),tumor necrosis factor α( TNF-α)and C reaction protein( CRP)levels and smoking and body mass index( BMI)in the elderly patients with stable chronic obstructive pulmonary disease( COPD ). Methods Elderly participants including 50 cases smokers with stable COPD,45 cases ex-smokers with stable COPD and 40 cases healthy ex-smokers were recruited in this study,who were hospitalized in the People's Hospital of Gansu Province from Dec. 2012 to Feb. 2014. Serum IL-6,TNF-α and CRP levels were detected. Correlation analysis was performed between serum IL-6,TNF-α,CRP levels and smoking index( SI),BMI in COPD smokers. Results The levels of serum IL-6,TNF-α and CRP in smoking group were(45. 9 ± 12. 1)mg/L,(58. 2 ± 15. 8)ng/L,(12. 2 ± 4. 1) mg/L,significantly higher than those in stop-smoking group((38. 1 ± 9. 6)mg/L,(45. 9 ± 11. 2)ng/L,(8. 6 ±3. 2)mg/L respectively),and healthy controls group((17. 0 ± 9. 9)mg/L,(27. 3 ± 13. 2)ng/L,(6. 3 ±5. 2)mg/L),and the differences were significant(F=84. 934,57. 224,23. 023;P﹤0. 01). In patients with smoking index≥400,the levels of serum IL-6,TNF-α and CRP were(50. 1 ± 12. 1)mg/L,(64. 2 ± 12. 6) ng/L,(13. 4 ± 3. 7)mg/L,significantly higher than those in patients with SI ﹤400 group((41. 0 ± 10. 2) mg/L,(47. 8 ± 14. 0)ng/L,(10. 8 ± 4. 2)mg/L respectively),and the differences were significant( t=2. 845, 4. 343,2. 347;P ﹤0. 01 or P ﹤0. 05 ). The levels of serum IL-6,TNF-α and CRP in smoking group were positively correlated with SI(r=0. 458,0. 438,0. 313;P﹤0. 01 or P﹤0. 05). The levels of serum IL-6,TNF-αwere negatively correlated with BMI,and the correlation coefficient were - 0. 358,- 0. 319( P ﹤0. 05). Conclusion The increase of serum IL-6,TNF-αand CRP caused by smoking may play an important role in the pathogenesis of COPD. And chronic smoking is the reason of the decline of BMI in COPD patients,and the decline of BMI is related to the high levels of serum IL-6 and TNF-α.

Objective To summarize the experiences of Nuss procedure with thoracoscope for repairing pectus excavatum.Methods 21 cases of pectus excavatum were treated by Nuss procedure with thoracoscope.In these patients,10 had symmetric pectus excavatum and 11 had asymmetric one.Results The operation in all patients were successful.The mean operating time wag(70.7±9.6)min and the mean intraoperative blood loss was(20.3±10.9)ml.The average hospital length of stay was(5.3±1.1)days,the average durante dolors was(6.9±4.0)days.The exceUent rate was 81.0%(17/21),including 90.0%(9/10)in symmetric pectus excavatum and 72.7%(8/11)in asymmetric pectus cxcavatum.Conclusion Nuss procedure is easy to perform,with minimal invasion,short operating time,and less blood loss.Nuss procedure is suitable for the symmetric pectus excavatum.

Objective To systematically evaluate the health status and intervention measures in the US Armed Forces, and to provide reference for the development of health promotion strategies in our army.Methods The PubMed, Medline, Springer, Elservier, HighWire and CNKI Database were searched electronically, with assigned search strategy for American military health status and intervention measures published from Jan.1997 to Dec.2015.Results There were 25 of pieces literature about training injury, low back pain, posttraumatic stress disorder, depression and cardiovascular disease that were screened.Conclusion The main health problems facing the US Armed Forces and the focus of the intervention measures involved training injuries, low back pain, mental illness and cardiovascular disease.Protection of military health is shifting from the single disease prevention to diversified comprehensive maintenance in the new era.

0.05). The daily average intake of protein, fat and carbohydrate was similar to the RNI. The energy percentage of three meals was 4∶4∶2. Conclusions The incidence rate of hyperlipemia is high. It is a dangerous module which affects the health of the old. Thus, the diet for the old should be improved for their health.

Physical therapy is one of the core courses of rehabilitation therapy in higher vocational education. This paper would introduce the experience of choice of materials, contents and teachings as well as the teachers construction. Some suggestions in course construction were discussed.

Objective To explore risk factors in the mortality of casualties and to find a way to improve trauma emergency service. Method The possible factors likely related to the mortality of casualties were taken into account based on each stage of trauma emergency so as to find the independent risk factors by using univariate and multivariate analyses. Results A total of 3 659 casualties were enrolled in this study.Of them, 226 casualties died and the mortality rate was 6.18%. Following factors were related to mortality after univariate analysis: age, cause of trauma, injury severity score, Glasgow come scale come on the scene, professional emergency treatment on the scene, intubation in the ambulance, debridement and hemostasis in the ambulance, low blood pressure at admission, closed drainage of pleural cavity, emergency operation, CVP monitoring in ICU and mechanical ventilation in ICU. After multivariate analysis, six factors were independently related to the mortality of casualties as follows: Glasgow coma scale, injury severity score, mechanical ventilation, blood pressure at admission, age and professional emergency treatment on the scene. Conclusions It has a great significance to investigate the risk factors of mortality for casualties. Severity of trauma and age were independently associated with the outcomes of trauma. Besides, improving prehospital care and stabilizing the trauma patients in early phase can further decrease the mortality.

Objective To investigate the prevalence of latent tuberculosis infection(LTBI),and to identify the risk factors in primary schoolchildren from Shanghai through the population-based field investigation combined with the tuberculosis infection enzyme-linked immunospot assay(T-SPOT.TB)assay.Methods The children in grade 4 and 5 were enrolled from four primary schools in Pudong new district and Yangpu district of Shanghai.Questionnaire interview was applied to investigate the soeiodemographic and clinical information related to LTBI.The T-SPOT.TB assay was used to detect LTBI in the enrolled subjects.Univaitate and multivariate analyses were used to identify the risk factors associated with LTBI among the primary schoolchildren.Results Totally 472 schoolchildren were enrolled in the present study,with 439(93.0%)being vaccinated with bacillus calmette-guerin (BCG) and ten (2.1%) having contact history with tuberculosis (TB) patients.Among the 472 eligible subjects,16(3.4%) children were T-SPOT.TB positive,who had no clinical symptoms andsigns relevant to TB and were defined as LTBI.The LTBI prevalence in BCG vaccinated and unvaccinated children were 2.7% and 12.1%,respectively (OR:6.972;95%CI:1.834-26.500);those in TB contacts and children without TB contact history were 30.0% and 2.8%, respectively (OR: 16. 38; 95% CI: 3. 692-72. 700). Conclusions The prevalence of LTBI among senior schoolchildren in Shanghai is 3.4%. BCG vaccination is protective for children from LTBI, while daily contacts with TB patients increases the risk of LTBI in schoolchildren.

Objective To determine risk factors in nosocomial infection of trauma patients during intensive care unit stay. Methods A retrospective study was carried out. A total of 1103 trauma patients admitted to the intensive care unit of five tertiary hospitals in Zhejiang Province in 2009 were reviewed. Demographic data, injury severity score and other variables related to the trauma services were collected. Univariate and multivariate analysis were processed to identify the independent risk factors of nosocomial infection in trauma patients during stay in intensive care unit. Results Overall, 171 patients( 15.5% )developed nosocomial infection during ICU stay. Of 1103 patients, 157 patients (14.2% ) died, and the 59 fatal patients were from infection group. The mortality rate in infection group was 34.7% , which was significantly higher than that in non - infection group (10.5% ). The independent risk factors of nosocomial infection in all the patients determined by using multivariate analysis included central venous monitoring, mechanical ventilation, age ≥65, the length of ICU stay > 14 days and injury severity score ≥ 16. For the severe trauma patients, central venous monitoring, mechanical ventilation, the length of ICU stay > 14 days were independent risk factors of nonsocomial infection. Conclusions The severity of injury, age, the length of ICU stay and invasive procedures were related to the nosocomial infection. To standardize the invasive procedures and to reduce the length of ICU stay may decrease the infection rate of trauma patients.
