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.

With the development of tissue engineering,the bone tissue engineering is developing rapidly. Engineering hone typically uses an artificial extracellular matrix (scaffold),osteoblasts or progenitors,and os- teoinductive factors which promote cell attachment,differentiation,and mineralized bone formation.Highly porous scaffolds play a critical role in cell seeding,proliferation,and new 3D-tissue formation.A variety of biodegradable polymer materials and scaffolding fabrication techniques for engineering bone have been developed over the past decade.This article reviews the scaffold design and fabrication methods tor engineering bone to analyze their ad- vantages and limitations.Various architectural parameters of scaffolds important for bone tissue engineering (e.g. porosity,pore size,interconnectivity) are discussed.

This experiment was based on a full-length SAMDC sequence from the drought stress induced cDNA library of Cleistogenes songorica.Two methods,absolute quantification and relative quantification,were used to analyze the gene expression under different tissue and drought stress treatment by real-time quantitaive PCR experiments and were compared each other,while CsSAMDC gene was used as a case.Leaves and roots tissue were sampled from the plants at 0,4,6,8,and 10 d of drought stress and 1 and 4 d after rewatering.The 2-CT method was used to analyze the relative changes in gene expression from quantitative real-time PCR experiments.A standard curve was generated by the purified plasmid DNA.The primer concentration in the realtime PCR was optimized.All absolute quatification data were normalized by the normalization factor from the most stable house-keeping genes in C.songorica.Relative quantification results using 2-CT method showed that CsSAMDC transcripts increased 5.93?0.71 fold in roots,down regulated 0.62?0.13 fold in leaves,under drought stress.Absolute quantification results showed that CsSAMDC transcripts up-regulated in roots significantly under drought stress as 1ong as 8 to 1 0 days after drought stress,while down-regulated in both roots and leaves after drought stress within 6 days and 1 to 4 days after rewatering,compared with control.CsSAMDC transcipt showed similar tendency of gene expression compared by using relative and absolute quantification methods.

Objective To observe the therapeutic effect of acupuncture plus oral taking Chinese medicine compared with that of oral taking Chinese medicine only for the treatment of insomnia.Methods Totally 64 patients were randomized into treatment group(33 cases)and control group(31 cases).The treatment group was treated by acupuncture with filiform needle[Baihui(GV 20),Sishen- cong(EX-HN1),Shenting(GV 24),Neiguan(PC 6),Shenmai(BL 62)and Zhaohai(KI 6)being the main points] plus oral taking Chinese medicine.The control group was treated by oral taking Chinese medicine only.All 64 cases were examined by SPIEGEL scale. Results The treatment group was better than the control group in general therapeutic effect and improvement of quality of sleep(P

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.

Objective The study was performed to analyze the diagnosis and treatment of blue rubber bleb nevus syndrome of Chinese patients by evaluating the researches in China.Methods Chinese Journal Full-text Database,Wangfang Data and Weipu Chinese Medical Journal Database were searched for the clinical data of the patients with blue rubber bled nevus syndrome.Results Among the 50 patients,31 cases were male,and 19 cases were female.All patients (100％) had the venous malformations of the skin.Thirty-five (70％) cases had melena,13 (26％) cases had bloody stool,and 35(70％) had dizziness and palpitation.Blue rubber bled nevus syndrome were diagnosed with gastroscopy (40/48,83.33 ％),coloscopy (30/41,73.17％) and small intestinal examination (23/25,92％).Fourteen cases received symptomatic treatment.Twelve cases received therapeutic endoscopy,which lesions were located in stomach and colon.Sixteen cases received operation,and 2 cases were treated by laparoscopy and endoscopy.Conclusions Blue rubber bleb nevus syndrome is a rare disease.The skin and gastrointestinal system are involved in all patients with blue rubber bleb nevus syndrome in China.The routine examination for diagnosis of blue rubber bleb nevus syndrome should include examination of the small intestine.It still needs further research about effective treatment of blue rubber bleb nevus syndrome.
