Objective To review published literatures comparing the safety and effectiveness of retroperitoneal laparoscopic partial nephrectomy (RLPN) with transperitoneal laparoscopic partial nephrectomy (TLPN) and provide reference for clinical work. Methods The search strategy was performed to identify relevant papers from the Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE, Google Scholar, China Hospital Knowledge Database, Wangfang Chinese Periodical Database, and VIP Chinese Periodical Database. All papers comparing RLPN with TLPN were included from 2000 to 2015.Two to three reviewers independently screened, evaluated, and extracted the included papers. A Meta-analysis was executed by using Review Manager 5.3 software. The interesting outcomes were tumor size, operating time, estimated blood loss, warm ischaemia time, length of hospital stay, positive margin rate, open conversion rate, overall complication rate, and recurrence rate. Results The literature search obtained 378 papers, then 10 of them were ultimately met the inclusion criteria and included in the systematic review. Finally, 6 of the 10 papers were included in the Meta-analysis. RLPN had significantly less operating time [P= 0.01, mean difference (MD)=-33.68, 95% confidence interval (CI) within (-60.35,-7.01)] and shorter length of hospital stay [P< 0.0001,MD=-1.47, 95%CI within (-2.18,-0.76)] than TLPN. Significant differences were not found between RLPN and TLPN in other outcomes. Conclusions RLPN may be equally safe and be faster than TLPN. Each center can choose a modality according to your own operating habits and experience.

Objective To study the short-term clinical efficacy of treating patients with advanced gastrointestinal cancer with lentinan injection and javanica oil emulsion injection.Methods Clinical information of 42 patients with advanced gastrointestinal cancer were retrospectively collected.The 42 patients were divided into two groups according to treatments,with 21 case in the control group who were treated with javanica oil emulsion injection,as well as 21 case in the treatment group treated with lentinan injection and javanica oil emulsion injection.The efficacy,quality of life (QOL) and adverse effects were observed after treatment for 3 weeks.Results 81.0％ (17/21)of patients in the treatment group improved in QOL,which was much higher than that in the control group 47.6％ ( 10/21 ) ( x2 =5.081,P =0.024 ).The objective remission rate was 19.0％ (4/21)and 14.3％ (3/21)in the treatment group and the control group respectively,with no significant differece bwtween the two groups( x2 =0.171,P =0.679 ).the disease control rate was 85.7％ (18/21)in the treatment group,which was significantly higher than that of 61.9％ (12/21)in the control group( x2 =4.200,P =0.040 ).The incidence of adverse effect related to hematological toxicity,liver and kidney function,the digestive tract and itching of skin were similar between the two groups (Ps ＞ 0.05 ).Phlebitis in the treatment group was not as frequent as that in the control group(P ＜0.05).Conclusion Treating patients with advanced gastrointestinal cancer with lentinan injection and javanica oil emulsion injection had high efficacy than treating only with javanica oil emulsion injection,and it improved QOL signifiantly with safety.

Objective To explore the clinical efficacy of treating pains suffered from metastatic bone cancer with composite kushen injection and pamidronate disodium injection.Methods The clinical information of 60 cases of metastatic bone cancer patients suffered with pains was collected retrospectively.Thirty patients were assigned to the treatment group and 30 to the control group according to the treatment they underwent.The control group were treated with pamidronate disodium injection for 3 cycle,the treatment group were additionaly treated with composite kushen injection.The differences of two groups cases were compared in respect of the relief of pains and the changes of performance status (PS) and the incidence of adverse effects after treatment for 3 cycles.Results The objective remission rate of bone pain was 60.0％ (18/30) in the treatment group,which was significantly higher than that of 30.0％ (9/30) in the control group was higher( x2 =5.455,P=0.020 ).The incidence of adverse effect was 40.0％ (12/30) in the treatment group and 46.6％ (14/30) in the control group,with no significant difference between the two groups( x2 =0.271,P =0.602).In the treatment group the performance status of patients was( 2.30 ± 0.70 ) after treatment,which was better than that of( 1.80 ± 0.80 )before treatment(t =15.000,P =0.042),wheras there was no significant difference on performance status in the control group.Conclusion Kushen injection has synergistic effect with pamidronate disodium injection in treating pains with matstatic bone cancer.It could improve the short term efficacy,and significantly relief the pain and improve the quality of life.

A total of 68 patients with histologically proven endometrial cancer were preoperatively evaluated with a 3.0 T magnetic resonance (MR) unit.Two radiologists interpreted the depth of myometrial invasion on T2-weighted and diffusion-weighted(DW) MR (b =700 s/mm2) imaging.Myometrial tumor spread was classified as superficial (＜ 50％) or deep (≥50％ myometrial thickness).Statistical methods included Kappa statistics for reader agreement,accuracy assessment and receiver operating characteristic analysis for diagnostic performance comparison.For assessing the depth of myometrial invasion,the diagnostic accuracy,sensitivity and specificity were as follows:T2-weighted imaging-reader 1st,61.8％,60.0％ and 65.2％;reader 2nd,66.2％,64.4％ and 69.6％ ; T2-weighted combined DW imaging-reader 1st,86.8％,84.4％and 91.3％ ; reader 2nd,89.7％,86.7％ and 95.7％.Reader agreement was excellent for T2-weighted combined DW imaging (Kappa =0.818).For assessing deep myometrial involvement,ROC analysis showed that the diagnostic accuracy was significantly higher on T2-weighted combined DW imaging than that on T2-weighted imaging.The AUC (area under the curve) values measured by two readers on T2-weighted and T2-weighted combined DW imagings were 0.626,0.879 and 0.670,0.912 respectively.The addition of 3.0T MR diffusion-weighted to T2-weighted imaging can improve the diagnostic performance of MR imaging in the assessment of myometrial invasion.

Objective: To use in vivo fluorescence image analysis system for evaluating the efficacies of pVAX1-Ag85A and pVAX1-Ag85B DNA vaccines in treatment of bladder cancer cell-implanted tumors in mice. Methods: Discosomasp red fluorescent protein (DsRed) stably transfected bladder cancer BTT cell line (BTT-DsRed) was established and BTT-DsRed cell-implanted mouse model was constructed. Six days later, 24 BTT-DsRed-bearing mice were randomly divided into pVAX1-Ag85A DNA vaccine group, pVAX1-Ag85B DNA vaccine group, and saline group through injecting the pVAX1-Ag85A, pVAX1-Ag85B, and saline into the right hind limbs of mice, respectively. The growth and metastasis of implanted BTT-DsRed tumors were examined by in vivo fluorescence image analysis system. Results: BTT cell line stably transfected with DsRed (BTT-DsRed) was successfully established. Fluorescence visible mouse model was successfully es-tablished by inoculating BTT-DsRed cells into hind limbs of mice. After treatment with pVAX1-Ag85A or pVAX1-Ag85B for 2 weeks, the in vivo tumor fluorescence intensity in pVAX1-Ag85B group was significantly lower than that in the saline group (P <0.05). After 3 weeks, tumor fluorescence intensities in both pVAX1-Ag85A and pVAX1-Ag85B groups were significantly lower than that in the saline group (P < 0.01). But the efficacies of pVAX1-Ag85A and pVAX1-Ag85B groups were similar (P > 0.05). The distant lymphatic metastasis rate in pVAX1-Ag85B group was significantly lower than those in the saline (25.0% vs 87.5%) and pVAX1-Ag85A groups (25.0% vs 62.5%) (P <0.05). Conclusion: In vivo fluorescence image analysis system can dynamically, sensitively and visually evaluate the anti-tumor effects of DNA vaccines against bladder cancer cell-implanted tumors. Both pVAX1-Ag85A and pVAX1-Ag85B DNA vaccines have anti-tumor effects for bladder cancers.

Objective To evaluate the clinical manifestations, endoscopic features and the clinical pathological characteristics of H. heilmannii-associated gastritis, and to compare these variables with those of H. pylori-ussociated gastritis. Methods The clinical data, endoscopic findings and pathologic characteristics of 3107 patients, who underwent endoscopy from 2005 to 2007, were retrospectively analyzed. Results Twenty-five cases of H. heilmannii infection were identified, the infection rates of H. heilmannii and H. pylori were 0.80% (25/3107) and 4.12% (1060/3107) respectively. Three cases were mixed infections. Of 25 patients, 20 showed such gastroenterologic symptoms to a greater or less extent as abdominal distending pain,nausea and anorexia, and other 5 cases were asymptomatic. All 25 patients showed chronic gastritis by en-doscopy, including chronic superficial gastritis (7/25, 28% ), erosion ( 3/25, 12% ), chronic atrophic gastritis (4/25, 16%), bile reflux(1/25, 4%), ulcer (1/25, 4%), polyp (1/25, 4%) and duodenal bulbar inflammation (2/25, 8% ). In rapid urease test, 3 cases were hyper-positive, 3 cases positive, 7 ca-ses mild-positive and 12 cases negative. According to histological observation, H. heilmannii scattered or ac-cumulated within the gastric pits, glandular lumen or mucus. The organism was observed in parietal cells with cell damage in one case. Sporadic lymphatic and plasmic infiltration were found in all patients with H.heilmannii infection, infiltration of neutrophils (12/25), gland atrophy and intestinal metaplasia (4/25)and lymphoid follicles (6/25) were also observed. Compared with H. pylori-associated gastritis, H. heilman-nii-associated gastritis showed less inflammation, less helicobacter density, mononuclear cell infiltration and neutrophilic activity ( P < 0.05 ). Conclusion H. heilmanaii mainly induces chronic gastritis, which is less severe than H. pylori-associated gastritis.

Objective To observe therapeutic effects of HuGanJieXian decoction on rats hepatic fibrosis induced by tetrachloride. Methods Rat models of hepatic fibrosis were constructed by intraperitoneal injection of tetrachloride.HuGanJieXian decoction composed of low, middle, and high dose curcumin were given to these rats respectively at the same time. Sho-saiko-to compound treatment group and Fufangbiejiarangan Tablets treatment group were made as positive control groups. After twelve weeks, all rats were executed. Serum samples were kept for measuring serum levels of PC-Ⅲ, LN, and HA. Left livers were extirpated for pathologic examination including H.E and Masson stainings. Grade of hepatic fibrosis were evaluated according to SSS system. The levels of superoxide dismutase (SOD) and malondialdehyde (MDA) of supematant centrifugated from hepatic tissue homogenate were detected. Results Serum levels of PC-Ⅲ, LN, and HA were depressed obviously in decoction groups compared with those of fibrotic group (P<0.05) , especially in the low-dose curcumin group.HuGanJieXian Decoction could increase the level of SOD and decrease the level of MDA (P<0.05) , especially in the low-dose curcumin group. Staining of H. E and Masson showed that degrees of hepatic fibrosis in decoction groups were improved obviously compared with that of the fibrotic group. Conclusion HuGanJieXian Decoction can improve rat hepatic fibrosis, the mechanism of this effect may be associated with protecting hepatic cell membrane and anti- peroxidative damage.

The gene encoding the phosphatidylserine synthase in Escherichia coli K12 Sgal-(ExPASy P23830) was amplified by PCR. After DNA sequence analysis, it was inserted into the inducible expressive shuttle vector pBES of Bacillus subtilis, which was constructed in the lab, and the recombinant plasmid pBES-pss was transformed into competent cells of the Bacillus subtilis strain DB104. The positive transformant DB104 (pBES-pss) was grown on Bacillus subtilis common fermentation medium, which contained 30?g/ml kanamycin. After 2 hours cultivation, sucrose was added and increased to the final concentration of 2% for induction and this phosphatidylserine synthase was secreted into the medium. The result of SDS-PAGE showed that the molecular weight of the protein was 52kDa and the result of enzyme coupling colorimetric method showed that the enzyme activity was 1.50U/ml. The recombinant Bacillus subtilis has increased the yield of phosphatidylserine synthase which will be used for industrial biosynthesis of phosphatidylserine.
