Objective:To analyze the therapeutic effect and safety of finasteride on aged patients with isolated systolic hypertension (ISH)complicated benign prostatic hyperplasia (BPH).Methods:A total of 84 aged ISH + BPH pa-tients admitted from Jun 2011 to May 2013 were selected.According to medication plan,they were divided into fin-asteride group (n=44)and routine treatment group (n=40,only received routine treatment because they cannot use finasteride).Course of treatment was all six months.International prostate symptom score (IPSS),quality of life (QOL) questionnaire score,prostate-specific antigen (PSA),incidence rate of acute urinary retention,maximum u-rinary flow rate (Qmax),postvoid residual urine (PRV),prostate volume (PV)and incidence rate of adverse reac-tions were compared between two groups.Results:Compared with routine treatment group,there were significant reductions in IPSS [(13.2±2.4)scores vs.(9.4±1.1)scores],PRV [(21.4±4.6)ml vs.(9.0±2.3)ml],PV [(36.8±3.8)ml vs.(29.5±3.0)ml],PSA [(2.45±0.74)μg/L vs.(1.26±0.48)μg/L]and incidence rate of acute urinary retention (17.50% vs.9.09%),P<0.05 or <0.01,and significant increase in Qmax [(10.2±2.4) ml vs.(13.7±3.8)ml]and QOL score [(3.1±1.0)scores vs.(4.7±1.5)scores]in finasteride group (P<0.05). There were no significant difference in incidence rates of adverse reactions between two groups,P>0.05 all.Con-clusion:Therapeutic effect of finasteride is significant and adverse reactions don’ t increase significantly in aged pa-tients with isolated systolic hypertension complicated benign prostatic hyperplasia.

[Objective]To evaluate the effect of integrated management of blood loss in total knee arthroplasty (TKA ) between gypsum fixed up, ice compress,elastic bandage and only with elastic bandage. [Methods]From January 2006 to August 2008,107 patients undergoing TKA were randomized divided into integrated management group( 54 cases) and control group( 53 cases).Sex,age and deseases in two groups were comparative.The patients in integrated management were treated with elastic bandage,gypsum fixed up,leg elevated by 35 degrees at the hip with knee extended, continuous cold therapy.The patient in control group were only treated with single elastic bandage.The loss of blood during 2 h, 12 h, 24 h postoperative were analyzed.[Results]The blood loss was 170 ml(85~505 ml),210 ml(105~560 ml), 260 ml(110~580 ml)at 2 h、12 h、 24 h postoperative in integrated management group,and 180 ml(110~900 ml), 320 ml(115~930 ml),390 ml(170~970 ml) in control group.The blood loss in integrated group was obviously and a statistically significant difference was found between the two groups (P

Background and purpose:miR-124 is considered to be a tumor suppressor in multiple tumors, including lung cancer, prostate cancer, bladder cancer, and breast cancer. However, its function is unclear in gastric cancer. This study aimed to explore the expression of miR-124 in human gastric mucosal epithelium cells and different gastric cancer cells, as well as gastric cancer tissues and matched para-cancerous tissues. The correlations of miR-124 expression with gender, age, histological grade, T stage, TNM stage, lymph node metastasis and prognosis of gastric cancer patients were analyzed.Methods:A real-time lfuorescent quantitative polymerase chain reaction (RTFQ-PCR) was employed for detecting the expression of miR-124 in human gastric mucosal epithelium cells and gastric cancer cells. The expression of miR-124 in gastric cancer tissues and matched para-cancerous tissues was detected by in situ hybridization.Results:The RTFQ-PCR results indicated that the expression of miR-124 was down-regulated in MKN-74, MKN-28, MKN-45, MGC-803, SGC-7901 and AGS cells compared to GES-1 cells.In situ hybridization showed that miR-124 was strongly expressed in normal gastric mucosa. However, low expression, focal positive expression or lack of miR-124 expression were observed in gastric cancer tissues. Statistical analysis showed that miR-124 was close-ly correlated to histological stage, TNM stage and node metastasis of gastric cancer patients, but not the age, gender and tumor size. The OS and DFS of the patients with low expression of miR-124 were shorter than that of the patients with high expression of miR-124. Multivariate analysis suggested that miR-124 down-regulation was an independent prog-nostic factor for survival in patients with gastric cancer.Conclusion:miR-124 is down-regulated in gastric cancer cells and tissues. The expression of miR-124 is correlated to histological stage, TNM stage, node metastasis and prognosis.

Objective Study the relationship between HLA antibodies production and the number of Gravidity.Methods A total of 856 pregnant women of first pretanal in Xiasha Hospital of Sir Run Run Shaw Hospital of Zhejiang University from Nov 2016 to Mar 2017 were recruited.The blood samples were collected during 24-28 weeks of pregnancy,and the expression of platelet-specific alloantibody was detected by solid-phase red cell adherence assay.Results There were 67 positive HLA antibody in pregnant women,and the antibody positive rate was 7.8％.There were 15 positive HLA antibody in 334 first pregnant women,14 in 214 two or more pregnancy pregnant women without abortion,10 in 107 pregnant women with once abortion,28 in 223 pregnant women with two or more abortion.The antibody positive rate respectively is 4.5％,6.5％,9.3％ and 12.6％.The production of HLA antibody was significantly associated with the numberof gravidity.Conclusion The antibody positive rate of two or more pregnancy is significantly higher than the fisrt pregnancy.

Objective To explore the effect of neural cell adhesion molecule (NCAM) on adhesion,migration and morphology of mouse bone marrow-derived mesenchymal stem cells (BMSCs).Methods We isolated and cultured BMSCs from wild-type and NCAM gene knockout mice.The expression of NCAM was detected by Western blot and immunofluorescence.Wound healing and adhesion assays were used to detect cell migration and adhesion ability respectively.The morphological changes were observed and the expressings of protein β1 integrin,E-cadherin,β-catenin and N-cadherin were analysed by Western blot.Results The migration and adhesion of BMSCs were significantly reduced after NCAM gene knockout.Meanwhile,the expression of β1 integrin was lower than those in wild-type BMSCs (P<0.01).The morphology of NCAM gene knockout BMSCs changed from irregular to flattened,and expressed epithelial identification marker E-cadherin and β-catenin (P<0.05).However,the expression level of mesenchymal identification marker N-cadherin was decreased (P<0.01).Conclusions NCAM is involved in adhesion and migration of BMSCs via regulating the expression of β1 integrin.Furthermore,NCAMmay negatively regulate the mesenchymal-epithelial transitions of BMSCs.

Objective To explore a new technique to treat the benign stricture at hilar bile duct of plastic anastomosis, so as to obtain the theoretical basis and the feasibilities of practical application in treating the benign stricture at hilar bile duct with plastic anastomosis through the animal experiments. Methods 30 miniature pigs were randomly divided into three groups. Group A (control group):2 centimeters of the bile duct above the duodenum was isolated;Group B:The same separation of bile duct with group A, then making physical injury on it with the clamps and electric heat;Group C:Making bile duct injury model in group C as group B,and then monitoring of the diet, feces, urine, ALT, AST and bilirubin etc. When the bile duct stricture was formed, taking the plastic anastomosis operation in this group. After all the operations, we observed the diet, mental state and the color of the urine of animals in all the three groups, and tested ALT,AST,T-BIL and D-BIL levels on the pre- and post-day and every 7 days after surgery respectively. After three months of the surgery,we executed all the pigs,picked up part of the liver tissue,then preserved them by liquid nitrogen for pathological examination. Results From the day before operative-day to the 30 days after operation, there was no significant change in ALT, AST, T-BIL and D-BIL in group A,while the relative indicators of group B and C had obvious changes ( <0.05) . The indicators of group B were significantly increased 21 days after surgery, compared with pre-operation and 14 days after operation respectively ( <0.05) . In group C, the indicators were significantly declined 14 to 21 days after the plastic anastomosis compared with pre-operation (<0.05) . Conclusions Treating benign stricture at hilar bile duct of miniature pigs by plastic anastomosis is feasible and practicable. This study provides an experimental basis for clinical application of plastic anastomosis in treatment of benign stricture at hilar bile duct.

Objective Using the Chinese anthropomorphic chest phantom to measure the absorbed dose of various tissues and organs under different noise index, and to assess the radiation dose of MSCT chest scanning with the effective dose(ED). Methods The equivalence of the Chinese anthropomorphic chest phantom(CDP-1C) and the adult chest on CT sectional anatomy and X-ray attenuation was demonstrated. The absorbed doses of various tissues and organs under different noise index were measured by laying thermoluminescent dosimeters(TLD) inside the phantom, and the corresponding dose-length products(DLP) were recorded. Both of them were later converted into ED and comparison was conducted to analyze the dose levels of chest CT scanning with automatic tube current modulation (ATCM) under different noise index. Student t-test was applied using SPSS 12.0 statistical software. Results The Phantom was similar to the human body on CT sectional anatomy. The average CT value of phantom are -788.04 HU in lung,45.64 HU in heart,65.84 HU in liver,254.32 HU in spine and the deviations are 0.10%,3.04%, 4.49% and 4.36% respectively compared to humans. The difference of average CT value of liver was statistically significant(t=-8.705,P＜0.05),while the differences of average CT values of lung, heart and spine were not significant(t value were -0.752,-1.219,-1.138,respectively and P＞0.05).As the noise index increased from 8.5 to 22.5, the DLP decreased from 393.57 mGy·cm to 78.75 mGy·cm and the organs dose declined. For example, the average absorbed dose decreased from 22.38 mGy to 3.66 mGy in lung. Compared to ED calculating by absorbed dose, the ED calculating by DLP was lower. The ED values of the two methods were 6.69 mSv and 8.77 mSv when the noise index was set at 8.5. Conclusions Application of the Chinese anthropomorphic chest phantom to carry out CT dose assessment is more accurate. The noise index should be set more than 8.5 during the chest CT scanning based on ATCM technique.

Objective To investigate the feasibility of resection of internal wall for pancreatic mucinous cystic neolplasms (MCN).Methods Successive observation and cyst wall thickness measurement of the pathological sections of 24 cases with pancreatic MCN admitted in our hospital during 2008-2011.One patient with pancreatic tail MCN was treated by resection of internal wall.Results The cyst wall thicknesses of the 24 cases vary from 2 mm to more than 2 cm,and the thicknesses of fibrous envelop near pancreatic vary from 0.1 mm to 8.0 mm.The fibrous envelop thickness of 17 cases were more than 0.5 mm(70.8％,17/24).These cases could be treated with resection of internal wall.Pancreatic leakage occurred in 8 of the 24 patients (33.3％,8/24).The patient treated by resection of internal wall had no pancreatic leakage.Conclusion We consider that 70.8％ cases of pancreatic MCN could be treated by resection of internal wall to cure MCN and avoid the possibility of postoperative pancreatic fistula.
