Objective To evaluate the in vitro inhibitive activities of mycophenolic acid against hepatitis B virus in vitro. Methods The different concentrations of the test drugs in DMEM were added to the well with the monolayer growth of HepG2.2.15 cells. The culture medium was refreshed with DMEM containing the appropriate drugs every 3 days. At 3rd, 6th and 9th days, the supernatant was collected for HBsAg quantitative assay, total RNA was isolated from cells for RT-PCR and realtime-PCR assays. Results It was found no significant anti-HBV effect of mycophenolic acid on concentration of 2～250 ?g/ml, and mini inhibitory efficacy of HBV replication on concentration of 1250 ?g/ml. There was significant anti-HBV effect of lamivudine on concentration of 5 ?g/ml. When combined with lamivudine mycophenolic acid can significantly potentiate anti-HBV activities of lamivudine, and it can get maximal inhibition effect on concentration of 10 ?g/ml. Conclusions Mycophenolic acid could inhibit HBV replication and potentiate anti-HBV activities of lamivudine.

Objective To evaluate the in vitro inhibiting activities of interferon-alpha (INF-?) against hepatitis B virus (HBV). Methods HepG2 2 2 15 cells were treated with INF-?. At 3rd, 6th and 9th days after treatment, the supernatant was collected for HBsAg quantitative assay, and total RNA of the cells was isolated for RT-PCR and realtime-PCR assay of HBV mRNA. Results There were no significant differences in HBsAg titer and virus mRNA level at 3rd and 6th days between the experimental and control groups. At 9th day, HBsAg titer and virus mRNA level in INF-? group were significantly lower than those in control group. And 500IU/ml INF-? could get maximal inhibiting effect against HBV. Conclusion INF-? can inhibit transcription and expression of HBV gene in HepG2 2 2 15 cells, which indicated that INF-? can inhibit HBV replication directly.

Objective To summarize complications and early clinical effect of less invasive stabilization system and the femoral condylar support plates in treatment of AO type C distal femoral fractures. Methods We reviewed 46 patients who had internal fixation of AO type C distal femoral fractures. Of all 46 patients, 25 were with less invasive stabilization sys-tem and 21 were with femoral condylar support plates fixation. Comparative analysis was performed using intraoperative in-dex, postoperative complications and the Evanich score at follow-up. Results All 46 patients were followed up with a mean time of 19.6 months after surgery. The difference in incision length, blood loss, fracture healing time was significant between the 2 groups(P＜0.05)but not in the duration of operations and hospital stays(P>0.05). The statistical signifi-cance was also found in the total incidence of postoperative complications and the Evanich score at the last follow-up(P＜0.05). Conclusion Patients with less invasive stabilization system fixation had the characteristics of less trauma, shorter fracture healing time, less postoperative complications and better functional recovery compared with femoral condylar sup-port plates. Less invasive stabilization system had became an ideal internal fixation in treatment of AO type C distal femoral fractures.

Objective To construct dual-luciferase reporter plasmids containing the wild type and mutant rat extracellular signal-regulat-ed kinase 1 (ERK1) gene 3' untranslated regions (UTR) which were used to detect rno-miR-15b-5p's putative target gene. Methods The rat ERK1 gene 3' UTR fragment was amplified by polymerase chain reaction (PCR) from PC12 cell cDNA and cloned into pmiR-RB-ReportTM vector. The mutant rat ERK1 gene 3' UTR fragment was obtained by overlap PCR and inserted into pmiR-RB-ReportTM vector. Successful wild type and mutant recombinant plasmids were confirmed by DNA sequencing. PC12 cells were co-transfected with rno-miR-15b-5p mim-ic and pmiR-ERK13' UTR or pmiR-ERK1-mut 3' UTR and then analyzed by dual-luciferase reporter assay system. The achieved mutation sequence of the target site TGCTGCT was mutated to CGAACGT and GTACACG, respectively. Results The wild-type reporter vector pmiR-ERK13' UTR and the mutant reporter vector pmiR-ERK1-mut 3' UTR were successfully constructed. The rno-miR-15b-5p mimic de-creased the activity of pmiR-ERK13' UTR plasmid (P<0.001) but did not decrease the activity of pmiR-ERK1-mut 3' UTR plasmid. Conclu-sion The recombinant pmiR-ERK13' UTR and pmiR-ERK1-mut 3' UTR plasmids were constructed successfully, and luciferase activities demonstrated that the 3' UTR of ERK1 gene might be a potential target of rno-miR-15b-5p.

Objective To synthetically evaluate the relationship between miR-31 and the prognosis of carcinoma and to investi-gate its related mechanism.Methods The correlative literatures of tumor prognosis were retrieved from the electronic databases PubMed,EMBASE and ISI Web of Science.The pooled hazard ratios (HRs)and 95% confidence interval(95%CI )were extracted. The prognostic data were performed the synthesis analysis.Results A total of 7 trials conformed to the inclusion criteria including accumulated 2 012 cases of carcinoma.Meta-analysis revealed that the decrease of miR-31 expression in the tumor patients had the poor prognosis (HR=0.784,95%CI :0.630-0.974);in the subgroup analysis,the synthesis results adopting the multivariable a-nalysis and China subjects were 3.512 (95%CI :1.797-6.865)and 1.574 (95%CI :1.062-2.333),which indicating that the in-crease of miR-31 expression predicted the poor prognosis;miR-31 had no statistical significance in the digestive system (P >0.05). Conclusion The prognostic role of miR-31 may possess the histological and regional specificity and has the potential as a novel marker.

Objective To explore the curative effect of deep-brain magnetic stimulation (DMS) on learned helplessness behavior in the chronic restrained stress (CRS) rat model. Methods Twenty-nine Sprague-Dawley rats were randomly divided into control group (n=8) and CRS group (n=21). CRS group was exerted chronic restrained stress, while the control group did not receive any stress, for three weeks. Then learned helplessness behavior was tested using Forced Swimming Test (FST) and the hopeless rats of the CRS group were divided ran-domly into sham group (n=6), DMS group (n=8) and citalopram group (n=7), that received corresponding treatment respectively. They were evaluated with FST again after one-week treatment. Results The immobile time in FST was longer in CRS group than in the control group after three-week stress (F=11.260, P=0.002). After one-week treatment, no significant improvement was found in the citalopram group (F=1.565, P=0.235), however, the immobile time in DMS group decreased (F=6.277, P=0.025), and was shorter than that in the sham group (F=5.560, P=0.036). Conclusion CRS could result in learned helplessness behavior, which could be alleviated with one-week DMS.
