Objective To investigate the status of smoking and drinking among the officers and soldiers in associated logistics army,analyze the feature and primary cause of service men' s smoking and drinking,and provide scientific reference for the intervention measures.Methods A questionnaire survey was conducted among 1102 officers and soldiers in associated logistics army in Guangdong.Results 95.6％ officers and soldiers knew smoking was harmful to health,and 94.1％ knew drinking was harmful to health.The rate of recognition of smoking and drinking harm in officers,high-ranking soldiers and obligatory soldiers were significantly different (P ＜0.001 ),and the rate of recognition in different educational background wasn't significantly different (P ＞ 0.05 ).34.5％ officers and soldiers smoked or drank for reducing pressure.The total smoking or drinking rate was 64.7％or 72.6％ respectively in the service men.The rate of smoking and drinking in the officers and soldiers were significantly different (P＜0.01).In total 713 smokers,28.3％ smoked occasionally,25.8％ often,and 45.9％ heavily.In 800 drinkers,56.6％ drank lightly,32.3％ moderately,and 11.1％ heavily.In all drinkers,45.9％ drank beer,11.5 ％ drank distillate spirit,12.1％ drank port wine,and 5.5 ％ drank imported wine and spirits.Officers drank beer or distillate spirit dominantly (49.2％ and 30.8％,respectively),while high-rank soldiers and obligatory soldiers (40.6％ and 59.3％,respectively) drank beer dominantly.16.9％ officers,1.6％ high-rank soldiers and 0％ obligatory soldier respectively drank heavily distillate spirit ( ＞ 250 g every time).Conclusion Heath education and good environment for service men should be provided to give up smoking and drinking,thus to further prohibit smoking and drinking in the army.

Objective To analyze the blood perfusion modes of retroperitoneal benign and malignant masses by real-time contrast-enhanced ultrasonography (CEUS). Methods Forty-five patients with retroperitoneal masses, including 18 benign and 27 malignant masses, were performed with CEUS. The perfusion of contrast agent, entering style and the vascular patterns of contrast agent were described. And the diagnosis value of perfusion characteristics was evaluated in retroperitoneal benign and malignant masses. Results The perfusion of CEUS showed significant differences in the entering style of contrast agent and the vascular patterns in malignant masses in comparison to benign masses. In the entering style of contrast agent, center enhancement of malignant masses was 70. 37% (19/27), periphery enhancement of benign masses was 72.22% (13/18) ,there was statistical significane in the result( P = 0.0069). To the vascular patterns level,there were 2 with level 0 and 11 with level 1 in benign group, 10 with level 2 and 9 with level 3 in malignant group, there was statistical significane between malignant group and benign group too( P=0.0206). Conclusions CEUS is benefit to improve the accuracy of diagnosis of retroperitonea malignant and benign masses.

Objective To investigate the clinical efficacy and safety of hyperthermic intraperitoneal perfusion chemotherapy (HIPC) in treatment of advanced colorectal cancer.Methods The Meta-analysis was applied to analyze 8 randomized controlled quantitative studies published at domestic and abroad.These patients treated by HIPC after radical operation with colorectal cancer were included for the treatment group,and those treated only by radical operation with colorectal cancer for the control group.Relative risk (RR) of outcome variable of 3-year and 5-year survival rate and safety between the two groups were compared.Results There were 8 selected literatures,including 1 501 cases,in which 765 cases for treatment group,and 736 cases for control group.RR of 5-year survival rate of the total patients was 2.39 (95% CI:1.66-3.45).RR of 3-year survival rate of the total patients was 2.13 (95% CI:1.45-3.13).The results demonstrated that HIPC could improve 5-year and 3-year survival rate,and sensitivity analysis confirmed the conclusions more reliable.The security was described in 5 literatures,the available information showed smaller potential security issue.Conclusions HIPC after radical operation of advanced colorectal cancer can increase 5-year and 3-year survival rate of patients,improve the prognosis of patients.Whether patients with increased incidence of postoperative complications related to the HIPC is no clear-cut conclusions for lack of related research.

Objective To explore the microsurgery methods in patients with early intracranial aneurysm rupture. Methods Sixty-seven patients with early intracranial aneurysm rupture received the emergency microsurgery after releasing cerebrospinal fluid from improved Paine point via pterion craniotomy. Thirty-nine patients received surgery within 1 d after intracranial aneurysm rupture, and the other 28 patients were within 1-3 d. Results The therapeutic effect was evaluated by Glasgow outcome score (GOS) at discharge. Among the 45 patients with Hunt-Hess Ⅰ-Ⅲ grade, cure was in 41 cases, improved in 4 cases. Among the 22 patients with Hunt-HessⅣ-Ⅴgrade, cure was in 6 cases, improved in 6 cases, moderate disability in 4 cases, severe disability in 1 case, and death was in 5 cases. Conclusions The microsurgery of clipping aneurysm directly via pterion approach is still by far the most reliable treatment. And releasing cerebrospinal fluid from improved Paine points can effectively reduce the acute brain swelling of early operation, which will make it an effective adjuvant therapy to emergency microsurgery of clipping aneurysm.
