Objective To study the inhibition effects of various gastrin-shNAs on gastrin expression in gastric cancer cell line BGC-823. Methods Four nucleotide sequences of shRNA were designed corresponding to various sites of gastrin gene.Four shRNAs were synthesized by in vitro transcription and transfected into gastric cancer cell line BGC-823 at the final concentration of 10nmol/L,20nmol/L,40nmol/L and 80nmol/L respectively.In situ hybridization and immunohistochemistry techniques were applied to investigate the inhibition of gastrin expression and screen the most effective shRNA.The inhibitory effect on gastrin mRNA of screened shRNA was further identified by RT-PCR.MTT assay was used to determine the inhibitory effect of 4 shRNAs at various final concentrations on the growth of BGC-823 cells. Results The gastrin mRNA and protein exression were suppressed distinctly 24,48,and 72hours after transfection,and exhibited time-and concentration-dependent tendency.The highest suppression efficiency on both mRNA(54.27?0.042)% and protein(41.69?0.038)% level occurred 72 hours later in the cells transfected with shRNAs.The RT-PCR result showed that the inhibitory ratio of shRNA3 on gastrin mRNA of BGC-823 was 48.1%.MTT displayed a proliferative inhibition of the BGC-823 cells after transfection of shRNAs with a concentration-denpendent tendency except the shRNA4 treated cells.Conclusion Four gastrin-shRNAs showed a significant inhibition effect on gastrin expression of gastric cancer cell BGC-823 on mRNA and protein level.shRNAs might be the most effective gastrin-shRNA.Inhibited gastrin expression by shRNAs resulted in a significant decrease of proliferative ability of BGC-823 cells.

Objective To evaluate the impact on long-term survival using elective transcatheter arterial chemoembolization (TACE) before liver transplantation (LT) to treat patients with hepatocellular carcinoma (HCC).Methods A medical literature search was conducted up to October 2011 to identify comparative studies which evaluated survival rates,recurrence rates,and disease free survival.Pooled odds ratios (OR) and 95 ％ confidence intervals (95 ％ CI) were calculated using either the fixed or random effect model.Results 571 patients were included into this meta-analysis:326 patients were treated with elective TACE before LT and 245 patients were not treated before LT.A comparison between the elective pretransplantation TACE group and the LT only group showed the odds risks (95％CI) of 1-,3-,5-years overall survival rate were 1.90 (0.09-3.33),1.19 (0.67-2.14),1.23(0.63-2.39),respectively.The odds risks (95％CI) of 1,3,5-years disease free survival rates were 1.36 (0.65-2.83),0.91 (0.48-1.75),1.16 (0.76-1.79),respectively.The odds risk (95％CI of recurrence was 1.60 (0.65-3.89).Conclusion Pretransplatation TACE improved 1-year overall survival,but it did not improve the 3 and 5 years overall survival,disease-free survival and recurrence rates.

We investigated health condition and evaluate the viability of Barthel's measuring scale for 1297 elder patients at 17 nursing homes.We nursed all patients by standards and performed a comparison study.The nursing percentages of highest and lowest levels were higher than the previous ones ( P ＜ 0.01 ),while the nursing percentage of normal level was lower than the previous one ( P ＜ 0.01 ).The cooperation between doctors and nurses became optimized through progressive patient care.Ideal nursing standard should be based upon the doctors' judgment and nurses' evaluation.The new standard will be more suitable for patients and easier to control for nurses.

Low-frequency repetitive transcranial magnetic stimulation (rTMS) is a non-invasive brain stimulation method that has been used in the treatments of stroke patients. Our purpose was to investigate the effects of low-frequency rTMS on the hand motor function recovery for stroke patients. After searching from electronic database from January 1990 to April 2012, we collected randomized controlled trials explored the low-frequency rTMS effects on the hand motor function rehabilitation. A total of 7 comparisons (N = 216) from 5 articles were included in this study. We summarized the effect size by calculating the standardized mean difference (SMD). Summary of effect size (SES) indicated positive effects of low-frequency rTMS on the finger motor ability (SMD = 0.58) and hand function (SMD = -0.98). Few adverse effects occurred. The evidence showed that low-frequency rTMS could improve the paretic hand recovery after stroke.

Objective To evaluate the effect of TLR2McAb and TLR4McAb on intestinal flora of DSS-induced colitis in mice. Methods Fifty healthy male BALB/c mice (SPF level), were randomly assigned into five groups: the control group( group A), the UC model group( group B), TLR2McAb intervention group( group C), TLR4McAb intervention group( group D) and TLR2McAb + TLR4McAb intervention group(group E). Clinical symptoms were evaluated by the disease activity index(DAI), while tissue sam ples were evaluated by histological scoring(HS). The quantities of mRNA for IFN-γ, IL-4 and IL-17 were determined by real-time PCR. Meanwhile, fecal samples were obtained directly from the cecum for microbiological studies. Results After the treatment with TLR2McAb and TLR4McAb, DAI and HS were decreased significantly. Compared with group A, inflammatory cytokines such as IFN-γ, IL-4 and IL-17 in group B were higher. Compared with group B, expression of these three cytokines in group C to E was all markedly decreased. Group A showed a considerable predominance of Lactobacillus spp and Bifidobacterium spp,while the UC model group showed a conspicuous increase of Escherichia coli and decreases of Lactobacillus spp and Bifidobacterium spp. After treatment with TLR2McAb or/and TLR4McAb, Lactobacillus spp and Bifidobacterium spp increased to the normal level. But counts of E. Coli in the three intervention groups were not changed. Conclusion TLR2McAb and TLR4McAb suppressed the development of DSS-induced colitis and increase cecum counts of Lactobacilli and Bifidobacteria.

Objective:To Construct 3-D standard external nasal morphological database for nasal prostheses.Methods:12 plaster models of 6 types of external nose were prepared and scanned by a lasser scanner.The data documents were primarily saved as .asc format. The digital noses were partitioned to six areas by the nasal anatomical features: Nasal bridge area,nasal tip and collumella area,left and right dorsal areas,left and right ala nostril areas, the surface model of each area was constructed and connected to a group. With adding the background color, the surface model of external nose was visualized from any observing angles; then the nasal length and width were measured and the original data were replaced by HAN standard data.12 digital nose models with the same size were obtained and the documents were saved by each type with both .asc format and .igs format.Results:Point-cloud data and surface model data of 6 types of standard external digital noses were obtained.Conclusion:The nasal morphological database may be used as the foundation for CAD/CAM technique preparation of nasal prostheses

Objective To evaluate the safety and feasibility of total retroperitoneal laparoscopic nephroureterectomy for a tuberculous non-functional kidney. Methods A total of 15 individuals diagnosed with unilateral non-functional kidney secondary to tuberculosis were encountered from January 2013 to January 2016. There were 12 male and 3 female patients with an average age of 47 (range 36~64 years old) in the cohort. All patients had normal renal function on the contralateral side and underwent the standard three-drug antituberculosis treatment for at least four weeks before surgery. Total retroperitoneal laparoscopic nephroureterectomy was performed in all patients, and the enlarged section of the distal ureter was managed using different auto-suture techniques. Results All the operations were successfully performed without conversion. The median operative time was 109 min (range, 75~138 min), the median blood loss was 157 ml (range, 70~230 ml), and the median hospitalization time was 7 days (range, 5~11 days). Renal vein injury, lumbar vein injury and rupture of distal ureter occurred in 1 patient, respectively. Peritoneum injury was observed in 3 patients. No serious perioperative complications occurred. Anti-tuberculosis chemotherapy was prescribed to all patients, with the entire course of treatment lasting five months. No recurrenceof tuberculosis of the bladder or the contralateral kidney was observed during the median follow-up period of 25 months. Conclusion Total retroperitoneal laparoscopic nephroureterectomy is a safe and feasible approach for the treatment of tuberculous non-functional kidneys, and it is minimal and rapid recuperation.
