ObjectiveTo study the effects and mechanism of survivin gene on invasion of prostate cancer cell.MethodsAfter PC-3 prostate cancer cell lines were transfected by survivin small interfering RNA (siRNA), the mRNA and protein of survivin and matrix metalloproteinase-2 and-9 were determined by real time RT-PCR and western blot assay, respectively. The anchorage-independent growth was examined by clon formation in soft agar, and invasion ability was evaluated by boyden chamber model.The invasion ability of cancer cells in vivo was determined by nude mice model. ResultsThe results from clon formation in soft agar showed that the colonies numbers of group of 3.125,6.250 and 12.500 nmol/L of siRNA were 17.8±1.6,13.6±1.5 and 8.8±1.4, and the control group was 22.6±1.8(P<0.05). The results from boyden chamber model exhibited that the cells numbers crossing filter membrane in group of 3.125,6.25 and 12.5 nmol/L of siRNA were 33.6±2.1,19.5±1.9,8.1±1.83, and the control group was 49.4±2.3(all P<0.05). The results in vivo showed that cancer cells of control groups invaded into striped muscle and blood vessel, and there were no these phenomenons in transferred group with survivin siRNA. Survivin siRNA could reduce expression level of MMP-2 and MMP-9 in prostate cancer cells(P<0. 01).Conclusions Survivin-directed RNA interference can inhibit invasion of human prostate cancer cell through down-regualting MMP-2,-9 genes.

ObjectiveTo investigate changes of sex hormone levels and sexual function in male patients after liver transplantation.MethodsBlood samples were taken from 69 male patients receiving liver transplantation pretransplantation and postoperative 3rd,7th,14th day,1st and 3rd month respectively.Serum estradiol and testosterone were measured by radioimmunoassay.Serum sex hormone binding globulin was measured by ELISA.Sixty-nine discharged adult male liver transplant recipients ( age ranging 24 -45 years) with a normally functioning allograft for at least 6 months were questioned on their pre-and post-operativesexualfunction compared with 23adulthealthy controls.ResultsPretransplantation serum estradiol and sex hormone binding globulin were significantly higher (87.56±31.21 vs.26.00 ±9.12,u=9.30,P＜0.0001,134.50±30.68 vs.51.04 ±12.05,u=12.69,P ＜ 0.0001,respectively),and testosterone was lower than normal controls (2.02 ± 1.28 vs.4.82 ± 1.48,u =-8.73,P ＜0.0001 ) and levels were correlated with MELD scores (r =0.80,P ＜0.0001,r =-0.77,P ＜0.0001,r =0.72,P ＜0.0001,respectively).Sex hormone levels were back to normal on postoperative 2nd week (serum estradiol) or 1st month (serum testosterone and sex hormone binding globulin).Compared with pretransplant status,sexual function improved significantly when evaluated on postoperative 6th month.ConclusionsLevels of serum sex hormone were correlated with MELD scores before liver transplant.After liver transplant,estradiol was back to normal level on postoperative 2nd week,testosterone and sex hormone binding globulin back to normal level on postoperative 1 st month.Sexual function significantly improves after liver transplantation.

Objective To investigate the prevention and cure effect of anisodamine gel on phlebitis caused by intravenous infusion of KLT. Methods 96 patients with intravenous infusion of KLT were divided into the experimental group and the control group, 48 patients in each group, and the skin at the top of transfusion puncture points of the patients of the experimental group was evenly embrocated with 2% anisodamine gel along the vein before 3 to 5 minutes of intravenous infusion of KLT, while the control group was without any treatment. After observing the situation of venous injury, the skin at the top of transfusion puncture points of the positive patients would be embrocated with 2% anisodamine gel. The incidence, degree of phlebitis and treatment effect were compared between the two groups. Results The incidence rate of phlebitis of the control group was 68.7%, of which grade II, III occupied 60.4%, while the incidence rateof phlebitis of the experimental group was 10.4%, in which there was no occurrence of grade II, III phlebitis. All the venous injury symptoms of 33 patients of the control group and 5 patients of the experi -mental group disappeared after treatment, and after statistical processing, the incidence rate of phlebitis in the experimental group and the control group showed significant differences. Conclusions The embrocating of 2% anisodamine gel can effectively avoid the occurrence of the phlebitis caused by intravenous infusion of KLT.

Objective To investigate the effect of prevention and treatment of venous injury caused by intravenous infusion of Delisheng with anisodamine gel.Methods 100 patients with intravenous infusion of Delisheng were randomly divided into the experimental group and the control group,50 patients in each group,and the skin at the top of transfusion puncture points of the patients of the experimental group were evenly embrocated with 2% anisodamine gel along the vein before 3 to 5 minutes of intravenous infusion of Delisheng,while the control group received no treatment.After observing the situation of venous injury,the skin at the top of transfusion puncture points of the positive patients was embrocated with 2% anisodamine gel,and the effect on venous injury was observed.Results The incidence rate of intravenous pain of the experimental group was 4%,there wasn't any occurrence of poor intravenous infusion or swelling of the infusion position.The incidence rate of poor intravenous infusion of the control group was 34% and phlebitis incidence rate was 42%,and intravenous pain incidence rate was 68%.All the venous injury symptoms of 39 patients of the control group and 2 patients of the experimental group disappeared after treatment.Conclusions The embrocating of 2% anisodamine gel can effectively prevent and treat the venous injury caused by intravenous infusion of Delisheng.

Objective To investigate the prevalence of cardiovascular and cerebrovascular diseases in the army old male hypertensive patients in Beijing. Methods From October 2011 to April 2014, old male patients in the geriatric department of the General Hospital of Chi-nese People's Liberation Army were enrolled and categorized into 3 groups: normotensive, well-controlled hypertensive and poorly-con-trolled hypertensive groups. The prevalence of cardiovascular and cerebrovascular diseases was recorded and binary logistic regression was used to analyze the differences among the groups. Results 719 old male patients were enrolled, 228 in normotensive group, 389 in well-con-trolled hypertensive group and 102 in poorly-controlled hypertensive group. Compared to normotensive group, there was more incidence of angina (OR=2.547, P<0.001), myocardial infarction (OR=2.493, P=0.003), cerebral thrombosis (OR=3.438, P=0.003) and peripheral artery atherosclerotic disease (OR=1.766, P=0.026) in the well-controlled hypertensive group, and it was more of angina (OR=4.123, P<0.001), la-cunar infarction (OR=2.810, P=0.020), cerebral thrombosis (OR=3.484, P=0.001) and peripheral artery atherosclerotic disease (OR=3.773, P<0.001) in the poorly-controlled hypertensive group. There was not significant difference of prevalence of cerebral hemorrhage (0.9%, 1%and 1%, respectively). Conclusion In the army old male hypertensive patients in Beijing, control rate of blood pressure was higher than com-mon population, but the prevalence of ischemic diseases was still higher than in the normotensive patients. Anti-hypertension and control of other risk factors could reduce the mobidity of cerebral haemorrahge.

In patients with renal transplantation, the levels of sTM, sEPCR and vWF each have positive correlation(r=0 595 P

The research of esophageal target is a difficult spot in the precise radiotherapy and the target mobility has an important effect for the radiotherapy of esophageal cancer.By different breathing control techniques,controlling the patient's respiratory may narrow target mobility so as to improve the accuracy of radiotherapy.But the present studies of the movement range of esophageal cancer with the respiratory control technologies have not come to a consistent standard.The area shape and position change of esophageal cancer target is a key problem that needs to be solved in the esophageal precise radiotherapy.

As a transcriptional repressor,Bmi-1 is a member of polyeomb group gene family.It may play an important role in self-renewal ability and proliferation of stem cell.At present,studies show that Bmi-1 is highly expressed in a variety of solid tumors,which can be regarded as one of the markers of cancer stem cells and has a close relation to the cancer development and progression and radiation resistance.It will provide an important target gene for the treatment of malignant tumors.

Objective To explore clinical characteristics and the perinatal effects of multiple systems in pre-pregnancy obesity patients with early-onset preeclampsia. Methods A total of 111 cases with early-onset preeclampsia in our Inpatient Obstetric Department were reviewed in this study. According to pre-pregnancy body mass index (BMI), patients were divided into normal before pregnancy group (BMI<28 kg/m2, n=56) and obese before pregnancy group (BMI≥28 kg/m2, n=55) . The body weight, BMI, weight gain during pregnancy, risk factors, clinical features, and clinical features of neonatal index were compared between two groups. The correlation between maternal and neonatal indexes and glucose and lipid indexes were compared. Results Obese before pregnancy was more prone to blood concentration and disorders of lipid metabolism. The serum levels of lipid, glycosylated hemoglobin (HbA1c), hematocrit, platelet and fibrinogen were significantly higher in obese before pregnancy group than than those of normal group. The induced neonatal acidosis and other organ damage, newborn Apgar score, pH, glucose were significantly lower in obese before pregnancy group than those of normal group. The residual alkali (BE), lactic acid (LAC), creatine kinase (CK) and creatine kinase (CKMB) were higher in obese before pregnancy group than those of normal before pregnancy group. Correlation analysis showed that maternal low density lipoprotein cholesterol (LDL-C), total cholesterol (TC), three acyl glycerol (TG) and HbA 1c were negatively correlated with neonatal Apgar score and pH, and which were positively correlated with neonatal LAC and CKMB. Both differences were significant (P<0.05 or P<0.01). Conclusion The dyslipidaemia in early onset preeclampsia in obesity patients before pregnancy is closely related with maternal and perinatal outcomes.
