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 study the clinical characteristics and related of the adverse drug reactions(ADR) induced by carbamazepine,and propose preventive solutions.METHODS: 102 cases of carbamazepine-induced ADR,reported in medical journals of China from January 2001 to December 2005,were collected and analyzed.RESULTS:Skin and its appendages received most impairment from carbamazepine-induced adverse reactions(representing 35.3%),followed by general impairment of the body and impairment of the blood & hematopoietic system.Combined use of drugs is liable to induce adverse reactions,indicated by the fact that 16.7% of the sufferers received treatment by combined use of multiple drugs.Most of the ADR occurred 1h after administration.CONCLUSION:Individual differences of patients and combined use of drugs are among the factors that result in carbamazepine-induced adverse reactions.

OBJECTIVE:To analyze the clinical features and correlation factors of ADR caused by second generation antihistamine drugs for references of clinical rational drug use.METHODS:A total of 128 cases ADR cases induced by second generation antihistamine drugs that met our criteria were obtained by retrieving the domestic literature database between 1986 and 2006,which were categorized and analyzed in accordance with the ADR categorization stipulated by WHO international drug monitoring cooperation center.RESULTS:Of the 128 ADR cases,more were seen in male than in female,38 presented cardiovascular system lesions,accounting for 29.69%,followed by lesions of skin and its appendants(28.13%) and systemic reactions(20 cases,15.63%).However,the prognosis of these ADR was satisfactory.CONCLUSION:The ADR caused by second generation antihistamine drugs are associated to many factors such as patients’ sex and physical condition as well as drug combination etc.Clinic should be alert to such ADR such as allergic shock and arhythmia in patients treated with second generation antihistamine drugs.

OBJECTIVE:To discuss the influencing factors of anticoagulation with warfarin in patients who had undergone artificial mechanical heart valve replacement and the relation between dosage regimens and international normalized ratio(INR).METHODS:123 patients who had undergone artificial valve replacement patients were followed-up.The patients were treated with warfarin therapy for anticoagulation after surgery,and given a regular follow-up.Patients' age,gender,and INR value etc were recorded and the adverse events including bleeding,embolism and death were observed.RESULTS:No death case was reported;femoral vein thrombosis occurred in 1 case;gingival bleeding occurred in 11 cases and urinary tract bleeding was noted in 3 case.The incidence of anticoagulation-associated ADR was close to that reported in overseas literature.CONCLUSION:According to INR,individual dose of warfarin should be administered on day 5 after artificial valve replacement.Maintaning INR at 1.5~2.0 can achieve certain anticoagulation efficacy and is relatively safe.
