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.

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 relationship between SHP1 and CD99 expression in Hodgkin lymphoma (HL) .Methods RT‐PCR and Western blot to detect the expression of CD99 and SHP1 mRNA and protein expression in IM9、KM3、L428、L428‐CD99 cells ;fluorescence confocal to observe the expression and co‐localization of CD99 and SHP1 ;transiently interference CD99 in IM9 cells and then detect the expressing of SHP1 mRNA and protein levels .Results SHP1 mRNA was low expressed in L428、KM3 and high expressed in IM9;gene and protein expression were consistent trend;in L428‐CD99 cell SHP1 mRNA expression and protein levels were higher than L428 cell;CD99 expressed in membrane and SHP1 expressed in cell plasma;transient interference CD99 ,SHP1 decreased in mRNA expression and protein levels .Conclusion In HL cells ,SHP1 expression related to the missing expression of CD99 ,and its mechanism remains to be studied .

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.
