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 investigate the influence of duodenal diverticula on cannulation time and complication in patients undergoing ERCP.Methods Data of 3 265 patients undergoing ERCP in Drum Tower Hospital affiliated to Nanjing Medical University between January 1,2008 and December 31,2014 were enrolled.The patients' information and endoscopic pictures/videos were collected.The duodenal diverticula,cannulation time,postoperative complications were analyzed.Results There were 2 599 (79.6％) cases of non-diverticula,445(13.6％) cases of one-diverticula,122(3.7％) patients with two or more diverticula,and 99 (3.0％) intradiverticular papilla.Patients with duodenal diverticula accounted for 20.4％ (666/3 265) of all patients who received ERCP procedure.The mean cannulation time was 6.62 minutes in all cases,6.30 minutes in non-diverticula group,7.63 minutes in one-diverticula group,8.07 minutes in two-or-more group,8.58 minutes in intradiverticular papilla group,respectively.There were significant differences in cannulation time and complication rate between the groups.Conclusion Duodenal diverticula may be one of the factors that affect the cannulation time.It may enhance the cannulation complications and prolong the cannulation time,especially in those with intradiverticular papilla.

Objective　To study the expression of p73 in human non-small cell lung cancer (NSCLC) and the relationship between p73 expression and clinico-pathological parameters. 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 explore an optimal model of three dimensional in vitro cell culture for simulating solid tumors in vivo . Methods The model of three dimensional cell culture was constructed under the conditions of inhibiting the cell wall attachment and stirring the medium. Multicellular spheroids (MCS) were cultured using microcarriers (CutiSpher). Drug sensitivity of monolayer cells (MC) and MCS was tested by MTT staining and cytometry, respectively. Ultrastructures of the MC and MCS were observed by transmission electron microscopy. Results Cells in three dimensional cell culture model without microcarriers were compacted into mass at 4 d while cells in MCS were found to attach to the microcarriers at 0.5 h. MCS had more than two layers of cells growing within it at 5 d. Compared with MC, MCS was more resistant to the anticancer drug, and had more plenty of organell and microvilli with more extensive and compact cell adhesion. Conclusion MCS has strong developmental properties and can simulate the cell cell interactions in vivo , especially cell adhesion, which may contribute to the drug resistance of MCS.

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 study change of the declarative memory in patients with the calcification of the pallidum.Method The Chinese version of Wechsler Memory Scale(WMS-RC)test and dmwing forgetting curve were applied in 30 patients and 30 normal controls.Results There was no differences in the WMS-CR test's scores between the two groups.The patients had poorly memory preservation rate at the delays of 2 hours((64.10±0.87)%Vs(44.83±1.57)%,P<0.01),despite normal memory preservation rate over 30 mins and the similar slope after the delays of l day in the forgetting curve.There were negative correlations between the size of calcification and the memory preservation rate at the delays of 2 hours and 9 hours(r=-0.743,r=-0.483.P<0.01).Conclusion The results may reflect the effect of the pallidum on"slower confiolidation"declamtive memory process which aroused by a consequence of the repeated firing of hippocampal-neocortieal connections while the patients have normal memory encoding and retrieval.

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.
