Esophageal cancer is a common malignant tumor. Most patients have already in the late stage of the disease when the diagnosis is confirmed and have lost the surgery chance. In recent years, esophageal stent has been widely applied in the treatment of esophageal stenosis caused by esophageal cancer. The clinical experience shows that the esophageal stent can effectively solve the problem of dysphagia. However, the ordinary esophageal stent has no therapeutic effect on the esophagus tumor. The esophageal stent loaded with ~(125)I seeds can not only solve the dysphagia problem but also can treat the primary esophagus cancer with its brachytherapy effect. This article aims to review the clinical application and the up-to-date research progress of the esophageal stent loaded with ~(125)I seeds.

cases of acute promyelocytic leukemia (APL) were treated with drugs of all trans retinoic acid (ATRA) and Proplylene glucol mannurate sulfate (PGMS).Complete Remission rate was 90%. Because of using Proplylene glucol mannurate sulfate (PGMS), the rate of DIC and the rate of death were decreased.

Objective To study the bacteriology, clinical characteristics and treatment of ventriculitis fol-lowing ventricular-peritoneal shunt. Methods The clinical data and bacteriological results of eight patients with ven-triculitis following ventricular-peritoneal shunt from April 1998 to April 2007 were analyzed retrospectively. Shunt de-vice was removed in all patients. Intraventricular and intravenous antibiotics were given until the infection was con-trolled,and a secondary shunt device was placed. Results In eight patients,five were infected by Staph. Epidermi-dis,one by a mixed infection of Staph. Aureus and Pseudomonas acruginosa,one by Staph. Aureus,and one by E. Co-li. All patients were given intraventricular and intravenous antibiotics therapy. 8 cases recovered well after treatment. Conclusion Ventriculitis following ventricular-peritoneal shunt is a dangerous complication and is not easy to cure. After the removal of shunt device, a satisfactory result could be achieved by the administration of intraventricular and intravenous antibiotics.

OBJECTIVE:To observe the clinical efficacy and safety of ezetimibe combined with simvastatin in the treatment of membranous nephropathy complicated with hyperlipidemia. METHODS:90 patients with membranous nephropathy complicated with hyperlipidemia were randomly divided into observation group and control group,45 cases in each group. All patients received health guidance,low-fat diet,and the drugs without interfere with regulating lipid,hepatoprotective and lipid metabolism were for-bid. Control group was orally given 20 mg Simvastatin tablet,qd;observation group was additionally given 10 mg Ezetimibe tab-let,qd. They were treated for 8 weeks. Clinical efficacy was observed,lipid levels [total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol (HDL-C)],aspartate aminotransferase (AST),ala-nine aminotransferase(ALT),urinary protein quatitation,creatine kinase(CK)before and 2,4,8 weeks after treatment,and the incidence of adverse reactions were compared. RESULTS:Total effective rates of membranous nephropathy and hyperlipidemia were 95.56% and 93.30% in observation group,which were significantly higher than 73.33% and 75.56% in control graup,with statistical significance (P<0.05) .There were no significant differences in TG,HDL-C and LDL-C levels before and 2,4,8 weeks after treatment,and TC level before and 2,4 weeks after treatment between 2 groups (P>0.05);after 8 weeks of treat-ment,TC level in observation group was significantly lower than control group,the differences were statistically significant (P<0.05). Compared with control group,there were no significant differences in AST,ALT,urinary protein quatitation and CK level between 2 groups before and 2,4,8 weeks after treatment(P>0.05). And there was no significant difference in the incidence of adverse reactions between 2 groups(P>0.05). CONCLUSIONS:Ezetimibe shows similar clinical efficacy with simvastatin in the treatment of membranous nephropathy complicated with hyperlipidemia,it can effectively reduce TC level,with good safety.

Objective To investigate the expression of syndecan-1 (SDC1) in glioma cells and the effects of synde?can-1 knockdown on the proliferation and invasion of A172 cells. Methods The expression of syndecan-1 in glioma cells was analyzed using quantitative Real-time PCR and Western blotting. A172 cells were transfected with lentiviral vector carrying SDC1 shRNA to establish a stable SDC1-silencing cell line. The cell proliferation was analyzed by MTT assay. Trypan blue exclusion assay and flow cytometry, and Transwell assays were performed to measure the migration and invasion abilities, respectively. The mRNA and protein and expression levels of SDC1, Proliferation Cell Nuclear An?tigen (PCNA) and Matrix Metalloproteinase 9 (MMP-9) were detected by using qRT-PCR and Western blotting. Results The expression levels of SDC1 were significantly different in different glioma cell lines. The stable SDC1-silencing cell line was successfully established, in which the mRNA and protein expression levels of SDC1 were significantly decreased (P<0.05). SDC1 knockdown significantly reduced the cell proliferation, migration(58.40±5.24 vs. 255.8±16.09、226.5± 22.84,F=126.4,P<0.05)and invasion(61.67 ± 16.26 vs. 233.70 ± 17.24、244.30 ± 28.15,F=69.87,P<0.05)compared with either control group or blank group. SDC1 knockdown also significantly decreased the mRNA and protein expression levels of PCNA and MMP-9 (P<0.05). Conclusion:SDC1 knockdown suppresses the capacities of proliferation, invasion and migration of glioma A172 cell, implying that SDC1 may serve as a novel target in the biotherapy of glioma.

Objective To investigate the incidence and influence factors of respiratory diseases in patients with type 2 diabetes and Alzheimer's disease. Methods One hundred patients with type 2 diabetes complicated with Alzheimer's disease were selected as the study group in our hospital from November 2015 to June 2017. One hundred type 2 diabetes without Alzheimer's disease who did physical examinations during this period were selected as the control group. We observed and compared the pulmonary functions and qualities of lives of each group, and used Logistic regression curve to do multivariate analysis. Results The number of patients with respiratory infection, chronic obstructive pulmonary disease and lung cancer in the study group was significantly higher than that in the control group (P＜0. 05). The blood glucose levels of the study group were higher than those of the control group (P＜0. 05), and the qualities of lives of the study group were significantly worse than those of the control group (P＜0. 05). Age, living environment, complications and depression have influence on the incidence of respiratory diseases in patients with type 2 diabetes and Alzheimer's disease on some level. Conclusion The morbidity of respiratory diseases in patients with type 2 diabetes and Alzheimer's disease were high, and the quality of life, age, living environment and complications were factors that cause respiratory diseases in patients with type 2 diabetes and Alzheimer's disease.

Objective To investigate the effects of intratumoral implantation of ~(32)P-CP-PLLA seeds on the normal canine liver tissue and to exolore the metabolism of ~(32)P-CP-PLLA seeds implanted in the liver of experimental dogs.Methods Twelve beagles were enrolled in this study.The dogs were randomly and equally divided into four groups:group A(185 MBq),group B(370 MBq),group C(740 MBq)and group D(0 MBq).By using laparotomy procedure ~(32)P-CP-PLLA seeds were implanted into dog's liver.CT scan was performed before operation as well as before the dog was sacrificed.All dogs were sacrificed three months after the implantation.Before the procedure and 1,2,4,8 and 12 weeks after the procedure the blood tests and serum biochemical tests were conducted.One dog from group B and group C was selected respectively and was fed in a metabolic cage.Within one month after the procedure the cpm in feces and in urine was determined every 24 hours.One dog was picked out from each of the three groups and was punctured to get its liver tissue for pathologic exam each time at 1,2,4,8 and 12 weeks after the implantation,and SPECT imaging was also performed at the same time.Pathologic study,both macroscopic and microscopic(including optical and electronic microscopy)was made to observe the liver damage after the dog was sacrificed.The statistical analysis was processed by using SPSS 13.0 software and the measuring data were expressed with mean±standard deviation((x)±s).Results Two months after the procedure,serological examination found that the serum alkaline phosphatase(BKP)in both group Band group C was significantly higher than that in other groups,the difference was statistically significant (P ＜0.05),and the BKP levels returned to normal in three months.The postoperative 30-day inspection of the urine showed that the radioactive particles slowly released into the body and eliminated from the body with the urine and feces,mainly through the renal excretion.The 30-day cumulative percentage of eliminated radioactive dose in the urine and in the feces was 6.34% and 11.64% respectively.No sign of particle displacement was found on SPECT imaging.On autopsy three months after the implantation,the size of the radioactive seeds became smaller and fragile.With the radioactive dose used increasing,the area of liver damage at the site of seed implantation became bigger,which was demonstrated on CT scan,macroscopic exam and pathologic study.The local damaged focus of the liver caused by ~(32)P-CP-PLLA seeds was manifested as a spherical lesion which was encysted by a layer of fibrous tissue with an edematous zone peripherally.Conclusion The implantation of ~(32)P-CP-PLLA seeds in dog's liver causes only localized hepatic damage with no general adverse effects.The implanted seeds can slowly release the radioactive dose and will not immigrate to other organs in the body.Besides,the seeds possess excellent stability,targeted orientation and safety.

Objective To investigate the effect of different gene expression levels of Syntenin on invasion and mi?gration of glioma cells and the underlying molecular mechanisms. Methods Lentiviral RNA interference was used to knockdown the expression of syntenin in U-87 cells. Real-time quantitative PCR was used to detect mRNA expression levels of syntenin . Transwell assay and adhesion assay were used to examine the invasion, migration and adhesion, re?spectively. Western-blot was used to detect the protein expression levels of Syntenin, AKT, p-AKT, and MMP-9. Re?sults The mRNA expression level of Syntenin was greatly reduced in interference group compared with empty vector group (P<0.01). The ability of invasion and migration was much lower in interference group than in empty vector group (P<0.01). However, there were no significant differences in invasion and migration between empty vector group and con?trol group. The adhesion ability of glioma U-87 cells was much higher in interference group than in empty vector group (P<0.05). However, when U-87 cells were seeded on 96-wells coated with HUVEC, the adhesion ability was much lower in interference group than in empty vector group(P<0.05). The protein expression levels of Syntenin, p-AKT, and MMP-9 in interference group were markedly decreased compared with empty vector group(P<0.05). There was no signif?icant difference in expression of AKT protein between interference group and empty vector group (P>0.05). Conclusion Syntenin may enhance the invasion and migration ability of glioma though up-regulation of p-AKT, which in turn pro?motes MMP-9 expression in a corresponding signal transduction pathway.
