Objective To study the effects of three kinds of endoscopic therapy on gastric varices. Methods In this study, the efficacies of endoscopic band ligation ( EVL) , endoscopic injection of tissue adhesives (histoacryl) and sclerotic agent (EIS) for gastric varices were assessed. Forty consecutive, non-randomized patients with gastric varices were prospectively studied. EVL was done for 11 cases, Histoacryl 15 cases, and EIS 14 cases, to control and prevent relapse of bleeding. Results In the following-up ( six months) period, the effective rate of EVL, histoacryl and EIS were 100. 0% , 100. 0% and 72. 7% ; the e-radicative rate 25. 0% , 30. 8% ,0 (P

To elucidate the signal transduction mechanism of systemic inflammatory response syndrome induced by LPS,Western blot analysis was used to assay the protein expression and phosphorylation levels of ERK, JNK,and p38 MAPK in murine KC which were stimulated by LPS. It was found that LPS treatment resulted in no significant change in their protein expression, but a rapid transient increase in their phosphorylation levels, which peaked at 30, 45,and 20 minutes,respectively; The values returned to mear baseline within 2 hours. Kinase phosphorylation levels of these three MAPKs induced by LPS were found to be dose dependent in a range of 10 pg/ml to 100ng/ml. No phosphorylation was observed in unstimulated cells. Among them, p38 MAPK shoned fastest and highest phosphorylation levels. The results show that LPS can markedly activate ERK, JNK,and p38 MAPK in KC, and p38 MAPK may play a more important role in LPS induced kupffer cell activation than ERR and JNK.

ObjectiveTo investigate the short-term effect of health education intervention on the recovery of new schizophrenia patients. Methods82 patients were randomly divided into observation group, in which patients accepted routine antipsychotic medication, general nursing and system health education intervention, and control group, in which patients accepted antipsychotic medication and general nursing. Brief psychiatric Rating Scale (BPRS) and Positive And Negative Syndrome Scale (PANSS) were used to assess the effects. ResultsThere was no difference in the score of every factor before intervention (P>0.05), but it became different after intervention (P<0.01 or P<0.05). ConclusionHealth education intervention can improve the effect on schizophrenia.

Objective To explore the effect and safety of transcranial approach for spheno-orhital meningioma. Design Retro- spective case series. Participants Thirty-two patients being operated with transcranial approach. Twenty-four cases were meningothelial meningiomas, 3 cases were fibrous meningiomas, 1 case was psammomatous meningioma, 2 cases were atypital meningiomas, 2 case were malignant meningiomas. Methods All patients underwent frontal-temporal craniotomy, the involved sphenoid wing bone and peri- orbit were removed to prevent recurrence. The superior orbital fissure and optic canal were decompressed, the dural and periorbital de- feet were repaired by autogenous temporal fascia or artificial dura. Main Outcome Measures Preoperative and postoperative exoph- thalmus and eyeball movement, the extent of tumor resection, the ratio of recurrence. Results The extent of tumor resection: 8 cases were Simpson gradeⅡ, 20 cases Simpson gradeⅢ, 4 cases Simpson grade IV. After surgery, proptosis were improved in all patients, ophthalmoplegia was found in 6 eases. There was no operation-related death or other significant complication. Tumor recurred in 6 cas- es. Conclusions Adequate exposure of the tumor and bony decompression of the cranial nerves can result from transcranial approach, all the involved bone should be removed in order to prevent recurrence. This approach is relatively safe and the ptoptosis are improved significantly. Complete surgical resection is difficult because of the involvement of the orbital apex, superior orbital fissure and cav- ernous sinus.

Objective To assess the safety and efficacy of endoscopic retrograde cholangiopancreatography (ERCP) for pancreaticobiliary diseases in children. Methods Data of 9 patients younger than 14 years who underwent ERCP at between November 2004 and May 2010 were indentified through a computer database search. Therapeutic methods, success rate and procedure-related complications were evaluated.Results A total of 9 patients underwent 17 ERCP procedures under anesthesia, including 16 therapeutic and 1 diagnostic procedure. The success rate was 94. 1% (16/17) and the complication rate was 11.8%(2/17), including 1 mild pancreatitis and 1 peri-pancreatic infection. Conclusion ERCP is an important tool with high safety and efficacy for diagnosis and treatment of pancreaticobiliary diseases in children.

Objective To study the role of Bid in simulated ischemia/reperfusion injury in cultured neonatal rat cardiocytes and its possible mechanism.Methods A cell culture model of neonatal rat(born within 3 days) cardiocytes was used to establish simulated ischemia/reperfusion model.Unrelated siRNA or Bid specific siRNA was transfected into rat cardiocytes by Oligofectamine.The activation of Bid and caspase-8 was detected by Western blotting.The apoptotic rate of cardiocytes was determined by flow cytometry.Results Bid and caspase-8 of cardiocytes were activatied in simulated ischemia/reperfusion injury model.The activation of caspase-8 of cardiocytes in Bid-specific siRNA group decreased significantly compared with those in simulated(ischemia/reperfusion) group and unrelated siRNA group;the apoptotic rate of cardrocytes(7.4%) was lower than those in simulated ischemia/reperfusion group(51.2%) and unrelated siRNA group(48.7%)(P

ObjectiveTo evaluate the feasibility of detecting the mutations of KRAS,EGFR in nonsmall-cell lung cancer and colorectal cancer patients with high resolution melting curve analysis. MethodsAt first,the mutations in KRAS exon 2 and EGFR exons 18 to 21 of 5 patients with non-small cell lung cancer and 5 patients with colorectal cancer were detected by high resolution melting curve analysis.Then the results were confirmed with direct sequencing. ResultsBy high resolution melting curve analysis,1 of 10 patients was found to carry EGFR 19 mutation who was harboring 2236-2250del mutation.By direct sequencing,consistent results of the patients with mutations orwithout mutations were got. Conclusion s The new high resolution melting curve analysis was more efficient,more convenient than direct sequencing.Moreover,it was a low-cost test,which was suitable for clinic test.

Data is the basis and soul of clinical trials. To obtain accurate data, strict and standard data management is essential, which can be effectively supported by quality control in statistical analysis. In this paper, we briefly introduce the concept of the quality control in clinical trials, and describe its contents and methods. We hope that this work will be helpful to the application of statistical quality control in data management of clinical trials.
