Methods　Expression of p7 3 gene was detected by RT-PCR in 32 human NSCLC tissues, tissues adjacent to ca ncer and non-cancer lung tissues. Results　p73 gene expression up-regulated substantially and detected in 87.5%(28/32) of human NSCLC tissues while expressed at low level in tissues adjacent to cancer and non-cancer lung tissues. Conclusion　Marked up-regulation of p73 gene expres sion is found in human NSCLC.

Objective To study the effects of collaborative care model on the negative mood and the quality of life of lung cancer patients. Methods Sixty patients were randomized into the observation group and the control group with 30 cases in each.The control group only received usual care,the observation group Was treated with collaborative care,encouraging patients and their families to participate in health care.Using SDS、SAS、activities of daily living(ADL)scale and St.George's Respiratory Question-naire(SGRQ)to evaluate the effects ofthe patients in both groups on admission and one months after the discharge.Results One months after the discharge,the scores of anxiety and depression among the observation group were lower than those of the control group;ADL grade and quality of life score in the observation group compared with the control group were significantly improved,the difference was statistically significant. Conclusions Application of collaborative care management can improve the state of anxiety and depression,reduce hospitalization time and medical costs as well as improve quality of life.

Objective To understand the awareness status of knowledge on malaria control among residents and students,so as to evaluate the effectiveness of health education during the elimination phase of malaria in Jinshan District ,Shanghai City. Methods In 2010 and 2014,the stratified sampling and cluster sampling methods were taken to select the investigation sites, including 3 villages,1 middle schools,1 primary school,then the residents above 15 years old and the students in the above se?lected sites were investigated by questionnaires to understand their awareness status on malaria control. Results In 2010,the general awareness rates of malaria control knowledge of the study objects were 74.22%,and those of the residents,middle school students,and primary school students were 75.68%,61.86%and 72.20%,respectively. There was no significant differ?ence between the awareness rates of objects with different gender(χ2=1.755,P>0.05). The rate of the residents was higher than that of the students(χ2=59.838,P<0.01). From 2010 to 2014,a series of health education on malaria control was car?ried out. In 2014,the general awareness rate of knowledge on malaria control was 96.03%,and those of the residents,middle school student,and primary school students were 92.28%,98.59%and 99.49%,respectively. The awareness rate of the stu?dents was higher than that of the residents(χ2=275.794,P<0.01). Conclusion Through the health education and communi?ty advocacy,the awareness rates of knowledge on malaria control among residents and students have improved and met the quali?fication of malaria elimination in Jinshan District.

An enrichment culture showing specific algae-lysing activity was isolated from the mixtures of different samples and Microcystis aeruginosa. The process of algal lysis was monitored by chlorophyll measurement, PCR, and denaturing gradient gel electrophoresis (DGGE). The result showed that the enrichment culture had still high algicidal activity against M. aeruginosa after 1/100000 dilution. Rubritepida sp. C1, Pseudomonas sp. C2 and Sphingomonas sp. C3, as accompanying bacteria, existed in M.aeruginosa. The bacterial community in M. aeruginosa showed significant change after adding the enrichment culture, where uncultured Flavorbacterium sp. A2, Sphingomonas sp. C3 and Hydrogenophaga sp. A3 were observed, and A2 became a dominant species. The obvious correlation can be seen between change of bacterial population and extinction of M. aeruginosa. Compared identification of pure bacterium with sequencing of DGGE band, it was inferred that uncultured bacteria were probably play an important role in controlling the growth and abundance of M. aeruginosa.

Objective To evaluate surgical complications and outcomes based on prostate size in patients with benign prostatic hyperplasia (BPH) treated with plasmakinetic enucleation of prostate (PKEP).Methods A retrospective review was conducted of PKEP performed in 326 patients with BPH.According to the prostate size on preoperative transrectal ultrasonography measurement,patients were divided into three groups:groupl:＜40ml (n =92),group2:40～80ml (n =155),and group3:＞80ml (n =79).Intraoperative and perioperative parameters were evaluated.Patient perioperative data and postoperative outcomes were compared.Patients were followed up at 1,3,6 and 12 months after surgery.Early and late complications were recorded.Results There were significant differences among three groups regarding the mean operative time (P ＜ 0.01) and the mean resected tissue weight (P ＜ 0.01).However,enucleation efficiency (P ＜ 0.01) in gm tissue per minute increased significantly as prostate size increased.Mean hemoglobin decrease (P ＞0.05),mean serum sodium decrease (P ＞0.05),mean postoperative irrigation time (P ＞ 0.05),mean catheter time (P ＞ 0.05) and mean hospital stay (P ＞0.05) did not differ significantly among three groups.Three groups had a similar and significant postoperative improvement in international prostate symptom score (IPSS),quality of life (QOL),maximum urine rate (Qmax),and post-void residual urine volume(PVR) independent of prostate size (P ＜ 0.01),but no significant difference was found among three groups during 1,3,6 and 12-month follow-up (P ＞ 0.05).Perioperative and postoperative complications did not depend on prostate size (P ＞ 0.05).Conchsions Although patients with a larger BPH required significantly longer operation time in PKEP,prostate size did not affect perioperative and postoperative complications or micturition improvement.

Objective To find an effective method for the treatment of mitomycin C extravasation injuries. Methods The rabbit model of mitomycin C extravasation was made and managed by different methods. The therapeutic efficacy in each group was assessed by using regression index and regression time. Results The therapeutic efficacy in ice compress group and ice compress plus amifostine group was better than that in other groups and the regression time was the shortest. There was no inflammation and necrosis in skin in ice compress group. Conclusion Ice compress, which can prevent inflammation and necrosis in skin, is one of the most effective treatment methods for mitomycin C extravasation injuries.

Objective To study the mechanism of multicellular drug resistance of pulmonary adenocarcinoma cell line A549 mediated by cell-cell adhesion. Methods We compared the sensitivity of monolayer cells (MCs) to adriamycin (ADM) with that of multicellular spheroids (MCSs) which was employed as a three dimensional cell culture model. Transmission electron microscopy was applied to observe the cellular ultrastructure. Bcl-2, Bcl-xL, and Bax expression levels were detected by flow cytometry and indirect immunofluorescent staining. Results Compared with MCs, MCSs had more than two layers of cells, more extensive and compact cell adhesion, and inlay junctions were found within them. MCSs were more resistant to ADM. At the same time, Bcl-2 and Bcl-xL expressions in MCSs were much higher. After treatment with ADM, expressions Bcl-2 and Bcl-xL increased markedly in MCSs. Conclusion MCSs could simulate the solid tumors in vivo and has multicellular drug resistance mediated by cell-cell adhesion. The possible mechanisms may be associated with the upregulation of Bcl-2 and Bcl-xL.
