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.

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.

Objective To evaluate the efficacy and safety of endoscopic mucosal resection (EMR) for rectal carcinoid tumors. Methods From January 2006 to January 2009, EMR was performed in 28 patients with rectal carcinoids, who were followed up to evaluate the therapeutic effect and safety. Results Tumor diameters varied from 0.4 cm to 1. 2 cm (mean 0.7± 0. 2 cm). Negative resection margin was a-chieved in 26 cases (92. 9% ), tumor margin within 0. 1 cm of resection margin in 1 (7. 1% ) , and two margins coincided in 1 patient (7. 1% ). Hemostasis was performed with metal clips in 14 patients (50% ) and argon plasma coagulation (APC) in 9 (32. 1% ). Except for rectal bleeding in 1 patient (3. 6% ) , no other complications were observed. There was no recurrence in any patients during a follow-up of 6-36 months. Conclusion EMR is a useful and safe method for treatment of small rectal carcinoid tumor which does not cross submucosal layer.

Objective To study the effect of fosinopril on the expression of NADPH oxidase subunit p22phox mRNA and the extracellular matrix (ECM) accumulation in the kidneys of rats with diabetes mellitus . Methods Diabetic rats induced by streptozotocin were randomly divided into control group(DM group) and fosinopril group (fosinopril 10 mg'kg-1·d-1) (DM+Fosin group) and treated for 12 weeks . Expression of p22phox mRNA of NADPH oxidase in kidneys was measured by RT-PCR . The expression of fibroneetin was studied by immunohistochemistry and matrix metalloproteinases 9 activity was detected by Zymography . Meanwhile, the kidney hypertrophy index, serum creatinine level and 24-hour urinary protein excretion were evaluated . Results The expression level of p22phox mRNA in the kidneys of DM+Fosin group rats was decreased by 45% than that of DM group at week 4 (P＜0 .05) . At week 8 fosinopril significantly decreased the expression of glomerular and tubulointerstitial fibronectin by 52,5% and 42 .9% respectively (P＜0 .05), while increased MMP-9 activity by 29 .6% (P＜0 .05) compared with DM group . Fosinopril significantly decreased 24-hour urinary protein excretion of diabetic rats from week 8 . Serum creatinine level, 24-hour urinary protein excretion and kidney hypertrophy index were significantly decreased by 35 .9%, 50 .2% and 17 .2% in rats of DM+Fosin group than those of DM group at week 12 (P＜0 .05) . Fosinopril did not affect blood sugar significantly . Conclusion Fosinopril has beneficial effect on diabetic nephropathy partly through inhibiting the expression of NADPH oxidase p22 phox mRNA .

Aim To observe the retinal angiogenesis and detect the altered expression of genes related with angiogenesis and oxidative stress during the develop-ment of oxygen-induced retinopathy ( OIR) in newborn mice. Methods OIR was established in newborn mice according to the protocol of Smith et al. Newborn mice at 7 days old were placed into 75 . 5% oxygen for up to 5 days, and then they were put in room air for another 5 days. Retinal neovascularization was ob-served by immunofluorescence staining with cluster of differentiation 31 ( CD31 ) . Gene expression was de-tected using Real-time PCR analysis. Retinal CD31 immunofluorescence staining assay showed that relative hypoxia induced retinal neovascularization in OIR mice after hyperoxia-induced subside of retinal microvascu-lar. Results Real-time PCR analysis showed that vas-cular endothelial growth factor ( VEGF) and its recep-tor ( VEGFR) such as VEGFA, VEGFD, VEGFR1, VEGFR2 gene expression were increased in OIR mouse as compared to control. Platelet-derived growth factor ( PDGF) and its receptor ( PDGFR) such as PDGFA, PDGFB, PDGFRa, PDGFRb gene expression was also increased in OIR mouse as compared to control. Matrix metalloproteinases ( MMPs ) such as MMP2 gene ex-pression were increased in OIR mouse as compared to control. Gene expressions of nuclear factor-related fac-tor ( Nrf2 ) and its downstream genes such as the two subunits of glutamate-cysteine ligase ( GCL):the cata-lytic subunit ( GCLC) and regulatory subunit ( GCLM) were both decreased in OIR mouse as compared to con-trol. Conclusion Our research demonstrates that the expression of genes related with angiogenesis is in-creased in retinas in the development of OIR in mice, whereas the expression of Nrf2 and its downstream genes is all decreased.
