Objective:Tumor suppressor gene nitrogen permease regulator like 2 (NPRL2), also called tumor suppressor candidate gene 4 (TUSC4), widely exists in all kinds of human tissues and is highly conserved in different kinds of biological species. The expression of NPRL2 is markedly decreased in many human tumor tissues, such as lung cancer, breast cancer,renal carcinoma, et al. NPRL2 is located in human chromosome 3p2.13, and participates in DNA mismatch modification, regulation of signal transduction du-ring cell cycle progression, and apoptosis induction. NPRL2 gene inactivation is related with the initiation and progression of several malignant tumors. The mechanism underlying the tumor-inhibiting activity of NPRL2 gene is not clear and needs to be further investigated.

OBJECTIVE:To review the curative efficacy and safety of itopride vs. domperidone in the treatment of functional dyspepsia(FD). METHODS:Randomized controlled trails(RCTs)of itopride vs. domperidone in the treatment of FD were enrolled and retrieved from Cochrane Library,PubMed,EMBASE,SCI,CBM,CNKI,VIP and Wanfang Database. Other retrieval was carried out by hand. Methodological quality evaluation and meta-analysis of RCTs were carried out. RESULTS:Of total 18 RCTs enrolled,11 RCTs were graded B and 7 RCTs graded C. Itopride group were superior to domperidone group in respect of total response rate,the relief rate of nausea,abdominal distention,belching,vomiting,epigastric pain and sour regurgitation. There was no statistical significance. The incidence of ADR in itopride group was lower than in domperidone group. There was no statistical significance in difference between two groups. The relief rate of anorexia and early satiety in itopride group were superior to domperidone group. Statistical significance was noted in difference between two groups. CONCLUSION:Recent study shows itopride has better effect than domperidone on FD,which should be confirmed by high quality study.

Anti-glutamic acid decarboxylase antibody-associated encephalitis is a kind of autoimmune encephalitis mediated by anti-glutamic acid decarboxylase antibody, which belongs to anti-neuronal intracellular synaptic protein antibody-associated encephalitis. Clinical manifestations include stiff-person syndrome, cerebellar ataxia, limbic encephalitis, seizures, etc., often associated with a variety of autoimmune diseases, rarely associated with tumors. Detection of anti-glutamic acid decarboxylase antibody is crucial for clinical diagnosis. Immunotherapy helps to relieve symptoms and improve prognosis. The incidence of this disease is low, and there are few reports at home and abroad. This paper intends to review the research on this encephalitis, hoping to improve the clinicians′ understanding and the level of diagnosis and treatment of the disease.

Objective By comparing clinical efficacy of percutaneous vertebroplasty with high viscosity bone cement and percutaneous kyphoplasty with conventional low viscosity bone cement for osteoporotic vertebral compression fractures,to explore the clinical value of treatment of osteoporotic vertebral compression fractures with high viscosity bone cement.Methods In this prospective study,100 patients with one-level OVCF and older than 70 years were diagnosed and treated in our hospital from June 2014 to December 2015,which were randomly divided into 2 groups (50 patients in each),applied unilateral percutaneous vertebroplasty with high viscosity bone cement and bilateral percutaneous kyphoplasty with conventional low viscosity bone cement,respectively.Collected data of basic clinical informations (including age,gender,body mass index,etc.),preoperative and postoperative visual analog scales (VAS),Oswestry disability questionnaire (ODI),operative time,intraoperative X-ray times,the amount of bone cement injection,leakage of bone cement,anterior vertebral height and kyphosis (Cobb angle) of preoperative and postoperative,and statistical analysis.Results There were significant improvement of both VAS and ODI scores of the postoperative 1 day,3 months and 12 months compared with preoperative,but there was no significant difference between two groups;The operative time,intraoperative fluoroscopy times,bone cement injection amount and intraoperative bone cement leakage of high viscosity bone cement PVP group were significantly less than those of low viscosity bone cement PKP group (P＜0.05);the anterior vertebral height and kyphosis improved,and there was a significant difference between preoperative and postoperative of low viscosity bone cement PKP group (P＜0.05).Conclusion The efficacies of unilateral PVP with high viscosity bone cement and bilateral PKP with conventional low viscosity bone cement for osteoporotic vertebral compression fractures are the same,which can relieve pain and improve function of life significantly.However,the high viscosity bone cement PVP is simpler surgical procedure,with shorter operative time,less intraoperative radiation,less bone cement leakage rate.The domestic bone cement injection device can significantly reduce the cost of surgery,it worth to be widely used for clinical application.

ObjectiveTo study the effect of lentivirus-mediated microRNA-21 RNAi on biological behaviors in human hepatic cancer cells.MethodsMicroRNA-21 specific siRNA gene was synthesized and cloned into the recombinant lentiviral vector,pGCSIL-GFP.HepG2 cells were infected by microRNA-21 siRNA recombinant lentivirus (miR-21-siRNA-Ⅳ).The HepG2 cells were devided into SI group,NC group and N group in vitro.The expression of the targets of miR-21 was detected by RT-PCR.Cell growth was analyzed by MTT assay.The invasion was dectected by tmnswell method.Apoptosis was detected by Hoechst33258.BALB/c nude mice were randomly divided into SI group and NC group.The growth of transplant tumors in BALB/c nude mice were observed.Results ( 1 ) The expression level of miR-21 was inhibited significantly by miR-21-siRNA-lⅣ.(2) The proliferation of HepG2 was also markedly suppressed in MTT at the 96 h point ( P =0.0031,P ＜ 0.05 ).(3) The number of cells that migrated through the chamber of SI group decreased ( P =0.0004,P ＜ 0.05 ).(4) The cell apopotosis in SI group increased markedly.In addition,the caspase 3 mRNA significantly increased ( P =0.0002,P ＜ 0.05 ).( 5 ) Tumor growth curve was not statistically different between groups ( P =0.0002,P ＜ 0.05 ).ConclusionsMicroRNA-21 specific siRNA suppresses the proliferation and migration of HepG2 cells and induces tumor cell apoptosis inhibiting the growth of transplanted tumor in Balb/c nude mice.

Objective To explore the influence of up-regulated Foxp3 on Treg function and kidney transplantation chronic rejection reaction in rat model.Method The kidney transplantation chronic rejection reaction rat model was established.The F344 kidney was transplanted to Lewis rats,and retroviruses highly expressing Foxp3 were constructed.The Banff 97 hierarchical diagnostic criteria were used to diagnose chronic renal allograft nephropathy (CAN).The rat models were divided into three groups by random number table.In experimental group,the pSCV-BsdRFP-FoxP3 retroviruses were injected into the rats via the tail vein after operation.In negative control group,the pSCV-BsdRFP retroviruses were injected into the rats via the tail vein after operation.In blank group,the normal saline was injected into the rats via the tail vein after operation.Enzyme-linked immunosorbent assay (ELISA) was used to detect the changes of interleukin-10 (IL-10) and tumor necrosis factor-β (TGF-β) immediate,1,2,3,and 4 weeks after operation.The rats were killed at 4th week after operation,and kidney tissues were taken out for pathological examination.Result The pathological changes of CAN were observed at 4th week.The typical chronic rejection change was seen at 12th week.The levels of IL-10 and TGF-β were increased,and reached the peak at 3rd week.The levels of IL-10 and TGF-β in experimental group were higher than in negative control group and blank group at 1st,2nd,3rd,and 4th week.At 4th week,obviously different degrees of intimal thickening,and mild hyperplasia of interstitial fibers,glomerular sclerosis and infiltration with lymphocytes and plasma cells were observed in the three groups.In the experimental group,the lesions were mildest,and apparent neointimal hyperplasia was found.Conclusion pSCV-BsdRFP FoxP3 retroviruses can reduce the kidney transplantation chronic rejection reaction in rat model,and have the potential treatment effect.
