Objective The epidemiologic evidences indicate that the benefits of using vitamin E (VE) against lung cancer remain controversial, the goal of the present paper is to know whether VE can produce the protective effect in lung cancer induced by benzo(a)pyrene B(a)P . Methods 225 Swiss mice were randomly divided into groups and treated with B(a)P and VE to systematically observe the intervention effects of VE on mouse lung cancer caused by B(a)P. Results VE exhibited no protective effect on B(a)P-induced lung cancer in female mice and instead promoted B(a)P carcinogenesis; neither protective effect nor promotion effect was observed in the male mice. The mechanism by which VE intervention influenced B(a)P carcinogenesis and lung cancer in female mice might be more complex. Conclusion The results of the present paper suggest that VE should not be used to prevent lung cancer induced by B(a)P.

Objective To investigate the pathogenic bacteria types and distribution characteristics of critical patients with lower respiratory tract infection in neurosurgery department,and to analyze the high risk fac?tors of lower respiratory tract infections. Methods A retrospective analysis of 80 cases of critical patients with lower respiratory tract infection in neurosurgery department of General Hospital of People Liberation Army from April 2013 to April 2014 was carried out. The pathogenic bacteria types and distribution characteristics of lower respiratory tract infection were analyzed by means of bacterial identification,and single factor and multi factor Lo?gistic regression analysis was carried out to analyze the related factors of lower respiratory tract infection.Results One hundred and thirty?four strains of pathogenic bacteria were cultured from sputum of 80 cases of patients. Among which the gram negative bacteria were 109 strains,accounting for 81.34%(109/134),while the Gram positive bacteria were 17 strains,accounting for 12.69%(17/134) and the fungi were 2 strains,accounting for 1.49%(2/134).The proportion of three kinds of pathogenic bacteria had statistical significance(P=0.004, 0.001). The single factor Logistic regression analysis showed that,younger age,use of ventilator,use of antimi?crobial drugs and pulmonary infection rate were protective factors of lung infection(OR(95%CI)=0.586(0.475-0.722),0.708(0.574-0.873),0.827(0.697-0.981);P=0.043,0.007,0.000);disturbance of consciousness, tracheotomy,insert gastric tube, surgery and pulmonary infection incidence were risk factors for lung infection (OR(95%CI)=4.769(1.069-21.276),11.612(5.438-24.792),22.989(19.385-27.263),10.426(8.789-12.361);P=0.001,0.008,0.005,0.002).The multi factor Logistic regression analysis showed that there was a significant correlation between the trachea incision, the consciousness and the lower respiratory tract infection (OR(95%CI)=4.627(2.143-20.645),10.412(2.334-46.455);P=0.009,0.002).Conclusion Patients with conscious disturbance and tracheotomy were more likely to have lower respiratory tract infections. The pathogens of lower respiratory tract infections are Gram?negative bacteria,and the majority of pathogens are high resistance, and it is multi drug resistance.

Objective To evaluate the advantage and clinical value of javanica oil emulsion injection combined with radiotherapy for esophageal carcinoma. Method Randomized controlled trials (RCTs) concerning javanica oil emulsion injection combined with radiotherapy for esophageal carcinoma were made on electronic databases of CBM, CNKI, Wangfang, VIP and PubMed from 1990 to February 28, 2015. Quality of the included RCTs was assessed by Jadad scoring , and Meta-analyses were performed by RevMan5.3 software. Results Seven RCTs involving 575 patients were included in Meta-analysis. All studies were in low quality. The results of Meta-analyses showed that Javanica oil emulsion injection combined with radiotherapy for esophageal carcinoma, compared with control groups, could increase the recent curative effect (P < 0.000 01) and improve the quality of live (P = 0.000 8), decrease the hematologic toxicities (P = 0.03) and the incidence rate of radioaction esophagitis (P = 0.02), but not enough evidence was found to prove that it can enhance survival rate (P = 0.25). Conclusions The results of Meta-analysis indicate that javanica oil emulsion injection may have therapeutic effects on the treatment of esophageal carcinoma. Yet the effects of javanica oil emulsion injection still need to be confirmed by large multi-center randomized controlled trials.
