OBJECTIVE:To systematically review the efficacy of ursodeoxycholic acid(UDCA)in the prevention ofulcerative colitisassociated colorectal cancer (UC-CRC) and dysplasia (UC-Dys),and provide evidence-based reference for clinic. METH-ODS:Retrieved from Cochrane Library,EMBase,PubMed,CJFD,CBM,VIP and Wanfang Database,randomized controlled tri-als(RCT)or cohort studies about UDCA(test group)versus placebo(control group)in the prevention of UC-CRC and UC-Dys were collected. Meta-analysis was performed by using Rev Man 5.3 software after quality evaluation and data extraction by Co-chrane Manual 5.1.0. RESULTS:Totally 7 studies(3 randomized controlled trials and 4 cohort studies)were included in the analy-sis,involving 672 patients. Results of Meta-analysis of 3 RCT showed that there was no significant difference in the incidence of UC-CRC and UC-Dys between 2 groups [OR=0.95,95%CI(0.17,5.12),P=0.95];results of Meta-analysis of 4 cohort studiess-howed that there was no significant difference in the incidence of UC-CRC and UC-Dys between 2 groups[OR=0.74,95%CI(0.30, 1.84),P=0.52]. Results of subgroup analysis showed,the incidence of UC-CRC and UC-Dys in test group with low-dose UDCA (<15 mg/kg) was significantly lower than control group,the difference was statistically significant [OR=0.19,95%CI(0.08, 0.49),P<0.001];there were no signifficant diferences in the incidence of UC-CRC and UC-Dys in high-dose UDCA group[OR=1.97,95%Cl(0.53,7.25),P=0.31](≥15 mg/kg). There was no significant difference in the incidence of adverse reactions(P>0.05). CONCLUSIONS:UDCA can not decease the incidence of UC-CRC and UC-Dys,it only prompts a possible trend toward decreased UC-CRC and UC-Dys risk in low-doseUDCA.

Objective To investigate the effect of electroacupuncture (EA) on oocyte quality in patients with polycystic ovary syndrome (PCOS) undergoing in-vitro-fertilization and embryo transfer (IVF-ET).Method Totally 217 patients with PCOS undergoing IVF-ET were randomized into two groups by the random number table, 119 patients in an EA group and 98 in a control group. In addition to the long-term ovarian hyperstimulation given to the two groups, electroacupuncture was involved in the intervention in the EA group. The spindle, quality of eggs, and pregnancy result were observed and compared.Result The high-quality embryo rate was significantly higher in the EA group than the control group (P<0.05), and compared to the control group, the pregnancy rate was 8.36% higher in the EA group; it’s found that the number of eggs with spindle located between 11 and 1 o’clock was in a significant positive correlation with the level of E2 on the HCG administration day and the high-quality embryo rate (P<0.01); the EA group had a markedly higher ratio of eggs with spindle located between 11 and 1 o’clock compared to the control group (P<0.05); electroacupuncture markedly reduced the dosage and duration of using Gn in the PCOS patients (P<0.05). Conclusion It’s proven the relation between spindle and the quality of eggs; electroacupuncture can enhance the quality of eggs and the pregnancy rate in the PCOS patients.

Background Diabetic retinopathy (DR) is one of the most important microvascular complications of diabetes,which has become one of the leading causes of blindness.Neovascularization is the main pathological manifestations of DR,but its mechanism is unknown.There is a clear need to investigate its pathogenesis which can offer potential therapeutic targets.Objective The aim of this study was to investigate the expression and distribution of visfatin and vascular endothelial growth factor (VEGF) in diabetic model rats.Methods This study was approved by Animal Ethic Committee of Inner Mongolia Medical University.Sixty SPF 8-week-old male SpragueDawley rats were randomized into the diabetic group and control group.The rats were housed under a condition that alternated between 12 hours of light and darkness,with free access to rat food and water.Diabetes was induced by intraperitoneal injection of 60 mg/kg (0.60 ml/100 g) of streptozotocin (STZ) and control rats received equivalent volume of buffer.The models were regarded as successful when blood glucose was ≥ 16.7 mmol/L.Rats were sacrificed 12 weeks after the injection of STZ and retinal specimens were prepared to detect the expression of visfatin and VEGF.Total retinal protein was isolated from the retinas of experimental and control eyes,and the expression of visfatin and VEGF was assessed by Western blot.Frozen cross sections of retinas of 5 μm thickness were used to perform double immunofluorescence staining with anti-visfatin and anti-VEGF antibodies.Results Mean body weight of the diabetic rats was (189.02±11.34) g and that of the control rats was (489.57 ± 14.48) g at 12 weeks post-injection,showing a significant difference between them (t =5.236,P =0.003).Mean blood glucose level was (29.25±3.86) mmol/L in the diabetic group and (5.32±1.01) mmol/L in the control group,demonstrating a significant difference (t =11.778,P =0.000).Double immunofluorescence staining showed reduced expression of visfatin and VEGF in the retinal nerve fibrous layer and glial cells in the control rats.A stronger staining for visfatin and VEGF was found in the various layers of the retina in the diabetic rats,with an expression level of visfatin (A value) of 346.26±41.23,which was considerably higher than that of the control group (102.07±65.01) (t =8.291,P =0.000) in 12 weeks after injection.Furthermore,the expression of VEGF in the retina was elevated in the diabetic group compared with the control group (A value) (415.88±92.15 vs.113.06±32.06) (t=10.067,P=0.000).Conclusions Visfatin might contribute to the pathologic progression of diabetic retinal,neovascularization and it might play a synergistic role with VEGF in the pathophysiology of DR.

Objective To establish an expression system of TCRγ9/δ2-Fc protein by baculovirus vector ex-pression system and identify biological function of expressed TCRγ9/δ2-Fc protein. Methods γ9Fc and 82 (OT3) Fc gene fragments were amplified by overlap PCR and inserted into expression vector pBACp10ph. The recombinant plasmid pBACp10ph-γ9/δ2(OT3)-Fc and the baculovirus DNA were co-transfected into st9 cells. The expression position of TCRγ9/δ2 (OT3)-Fc was identified by Western blot and the expression efficiency of γ9Fc and δ2 (OT3) Fc was tested by flow cytometry (FCM). Furthermore, the binding activity of TCRγ9/δ2 (OT3)-Fc protein with SKOV3 ceils and MNS protein was evaluated with laser scanning confocal microslopy and surface plasmon resonance (SPR). Results The recombinant vector pBACp10ph-γ9/δ2(OT3)-Fc was constructed and TCRγ9/δ2(OT3)-Fc protein was expressed in sf9 ceils. However, the expression efficiency of γ9Fc and 82 (0T3) Fc was quite differ-ent. It was proved that purified TCRγ9/δ2 (OT3)-Fc protein can bind with SKOV3 cell and MNS protein. Conclu-sion TCRγ9/δ2-Fc protein is successfully expressed in baculovirus vector expression system and TCRγ9/δ2-Fc protein can simulate the binding activity of TCR in vitro.

Objectives To analyze the relationship between phosphorylation of serine-3 of cofilin1 and Taxol resistance of ovarian cancer and to evaluate the prognostic value of cofilin1 phosphorylation in estimating ovarian cancer survival using clinical samples.Methods Wild type (WT) plasmids with over-expression of wild cofilin1,S3L plasmids with over-expression of cofilin1 and inhibited phosphorylation at serine-3,and siRNA-C plasmids with down-regulation of cofilin1 were constructed using molecular biology techniques.After the SKOV3 and SK-TR30 cell-lines were transfected with these plasmids,changes in biological characteristics and drug resistance after instant transfection were compared.Fifty-one elderly female patients with microscopically confirmed ovarian cancer,who had received chemotherapy with Taxol and cis-platinum (TC)after surgery,including 30 chemo-sensitive and 21 chemo-resistant cases,were recruited in this study.Immunohistochemical methods were used to detect the expression of cofilinl and phosphorylated cofilin in tissue sections from the two groups.Progression free survival(PFS)was analyzed.Results Compared with the control group,the proportion of cells increased at the G0/G1 phase(P=0.034)and decreased at the S phase (P=0.031),and the apoptosis rate decreased(P=0.020),in SKOV3 cells with high expression of cofilin1.However,these characteristics disappeared when the wild type was replaced with the inactive mutant S3L.When cofilin1 expression was down-regulated in SK-TR30 cells,the proportion of cells at the G0/G1 phase decreased(P=0.020).The expression of cofilin1 was detected in 56.7 % (17/30)and 57.1% (12/21),respectively,sections of ovarian tumor tissues of the chemo-sensitive and chemoresistant groups,and there was no statistic difference (x2=0.332,P =0.943)between the two groups.The expression of phosphorylated cofilin was much higher in the chemo-resistant group (85.7% or 18/21)than in the chemo-sensitive group (53.3% or 16/30),and the difference was statistically significant(x2=5.829,P=0.016).The higher expression of phosphorylated cofilin was also correlated with shorter PFS(x2 =21.440,P<0.01,95% CI:0.068-0.883),especially in the chemo-sensitive group.Conclusions Serine-3 phosphorylation status of cofilin 1 is associated with paclitaxel resistance in ovarian cancer,but the underlying mechanisms of regulation need further investigation.

Objective To study the influence of exposure factors on posttraumatic stress disorder( PTSD) and Posttraumatic Growth( PTG) in middle school students in disaster area four years after the Wenchuan earth?quake . Methods 1 526 students from four schools in Worst?Hit Areas were investigated with Self?compiled Earth?quake Exposure Factors Questionnaire,Posttraumatic Growth Inventory( C?PTGI) and Impact of Event Scale( IES?R). Data were analyzed by ANOVA and multiple linear regression analysis.Results The score of IES?R had sig?nificant difference between different levels of all exposure factors(F=5.75~89.10, P<0.05) ,and students with high exposure level((26.68±14.66),(26.80±15.56),(27.83±14.62),(29.02±15.36),(27.77±15.74),(26.74± 15.63),(25.43±14.32),(29.51±14.36)) had heavier symptoms of PTSD than those with low exposure level ((22.84±13.96),(23.98±13.99),(23.63±14.21),(23.53±13.96),(23.64±13.83),(24.24±14.15),(21.27± 14.35),(17.54±13.34)). Only exposure factors of having witnessed someone injured and having close friends se?riously injured or being killed could significantly influence the score of PTGI(F=11.82, P=0.001;F=6.23, P=0.013). Regression analysis showed that five exposure factors (grade,having felt scared,having family members being killed,having close friends seriously injured or being killed,having witnessed someone injured) had signifi?cant effect on IES(ΔR 2=0.141) ,but only one factor( having witnessed someone injured) had weak effect on PTG (ΔR 2=0.007).Conclusion Exposure factors can predict posttraumatic stress symptoms in middle school students in Wenchuan four years after the earthquake,and the emotion of fear is a strongest predictor,but they can not pre?dict posttraumatic growth.

Objective To investigate the effect of sodium citrate on the efficacy of oral midazolam premedication in children with congenital heart disease. Methods Forty ASA Ⅱ or Ⅲ children, aged 2-6 yr, weighing 12-20 kg, undergoing cardiac surgery, were randomly divided into 2 groups (n = 20 each): control group (gronp C) and sodium citrate group (group S). Group S received oral mixture of midazolam 0.12 ml/kg (0.6 my/kg), ketamine 0.12 ml/kg (6 my/kg), glucose 0.12 ml/kg (60 mg/kg) and sodium citrate 0.12 ml/kg (3 mg/kg), total volume 0.48 ml/kg. Group C received oral mixture of midazolam 0.12 ml/kg, ketamine 0.12 ml/kg and glucose 0.24 ml/kg, total volume 0.48 ml/kg. Hydrochloric acid (pH value 1.75) was mixed with the mixtures in the two groups and pH values were measured. Preoperative anxiety scale and the onset time,sedation score and parental separation score after receiving oral drugs were recorded in preparation room for anesthesia. After entering the operating room, HR, MAP and SpO2 were monitored, and the response to venepuncture in children and the adverse effects associated with oral drugs were also observed and recorded. Results The pH value was 1.97 in group C and 4.52 in group S. The parental separation score, sedation score and response score were significantly lower and the onset time was significantly shorter in group S than in group C. HR, MAP and SpO2 were in the normal range after entering the operating room. There was no obvious adverse effect after administration of oral drugs in the two groups. Conclusion Application of sodium citrate in the oral premedication in children with congenital heart disease can raise the pH value, shorten the onset time of midazolam, and enhance the sedative efficacy.
