Objective To determine the role of C-reactive protein(CRP) in evaluating the activity of ulcerative colitis. Methods Analysis was used to estimate the correlation of CRP with mean platelet volume in 41 patients with active ulcerative colitis and 17 patients ulcerative colitis in re-mission. The effects on disease severity were analyzed subsequently. Results Active UC patients sera CRP level(8.58 ±2.43)mg/L,which level of severe UC CRP (14.38 ±4.46)mg/L,the moderate level of CRP UC(6.68 ±2.35)mg/L,mild level of CRP UC(4.94 ±1.21)mg/L, while the remission stage UC patients CRP levels(3.05 ±0. 88)mg/L. CRP was found to be significantly higher in sera of patients with active ulcerative colitis than that in patients in remission (P ＜ 0.05). The sera level of CRP in inflammatory bowel disease at severe stage were significantly higher than those of medium stage (P ＜ 0. 05). CRP was observed to be slightly increased in sera of patients at mild stage (P ＜ 0. 05). Conclusion The increase of CRP could reflect the severity of active ulcerative colitis.

Objective To explore the endoscopic and clinicopathological features of progressive gastric carcinoma.Methods The datas of 172 cases of progressive gastric carcinoma confirmed by endoscpoy and pathology were collected from January 2002 to February 2006 in our hospital.The data of clinic,endoscope and pathology were retrospectively analyzed.Results The principal symptomof progressive gastric carcinoma was epigastric pain,weight loss,anorexia and anemia.Most of them were in gastric antrum,secondly in cardiac and gastric fundus.Type Ⅲ were the main styles by Borrmann's tandards,type Ⅱ was secondly.The most pathological type was adenocarcinoma,secondly was poorly differentiated.Conclusion Most of progressive gastr ic carcinoma has epigastric pain,and more epigastric pain appears in gastric antrum.The main styles by Borrmann's tandards is type Ⅲ,the most pathological type is adenocarcinoma.

Objective To compare the efficacy of 10-days sequential treatment( including rabeprazole,amoxillin, levofloxacin and tinidazole) and traditional trigeminy therapy (including rabeprazole, amoxillin and clarithromy-cin) for the eradication of helicobacter pylori ( Hp). Methods 90 patients with Hp positive who were detected by 14C urea breath test or gastroscope Hp test were randomly divided into two groups: the therapeutic group and the control group. The therapeutic group was treated with rabeprazole,amoxillin at first 5 days,rabeprazole,levofloxacin and tinidazole at the second 5 days,while the control group was treated with rabeprazole,amoxillin and clarithromycin for 10 days. The 14C urea breath test was detected after course of treatment finished in a month. Results The eradication rate of 10 days sequential treatment was 93. 3% and that of control group was 75. 6% ,and the difference between two groups was significant(P <0.05). Conclusion Comparing with traditional trigeminy therapy,the 10-days sequential treatment comprising rabeprazole and levofloxacin could achieve a higher eradication rate of Hp.

Objective To observe the operation of Nav1.6 voltage-gated sodium channels in rats with acute cerebral injury after electroacupuncture therapy and investigate the mechanism.Methods Male Sprague-Dawley rats were randomly divided into an ischemia control group (IC,n =48),an electroacupuncture group (ET,n =48),a nimodipine therapy group (NT,n =48) and a sham operation group (SO,n =24),and were treated accordingly.A model of acute cerebral ischemia was induced by occlusion of the right middle cerebral artery using the suture method.The expression of Nav1.6,the concentration of Ca2+ and infarct volume were observed at 6 h,1 d,2 d and 3 d after ischemia with the real-time quantitative fluorescence PCR,immunofluorescence and 2,3,5-triphenyl tetrazolium chloride methods,respectively.Results The Joshua score for neural function was zero in the sham operation group,and increased gradually in the three other groups 6 h and1 and 2 d after ischemia.The average Joshua score 3 d after ischemia was significantly lower than 1 d earlier in each group.In the ET group the expression of Nav1.6 was significantly upregulated at first,followed by a significant decrease.The concentration of Ca2+ behaved similarly.However,no significant changes were observed in the infarction volume percentage.At 3 d after ischemia the expression of Nav 1.6,the Joshua grades,the Ca2+ concentrations and the infarction volume percentage were all significantly lower in the ET group compared with the IC,NT and SO groups.Conclusion Electroacupuncture therapy after acute cerebral ischemia can inhibit the expression of Navl.6,reduced Na + inflow and calcium overload,and mitigate acute cerebral ischemic injury,at least in rats.The protective effect may be attributed to inhibiting the expression of Nav 1.6.

An experimental model of rhegmatogenous retinal detachment (RRD) in rabbits was established to simulate the pathophysiologic condition of human RRD. 24 rabbits were randomly divided into 3 groups and underwent vitrectomy with a vitrector and/or retinotomy with a Charles flute needle, with 12 in group I (vitrectomy and retinotomy), 7 in group I (retinotomy) and 5 in group III (vitrectomy). All animals underwent follow-up examinations with direct and indirect ophthalmoscopy and fundus photography 12 h and day 1, 3, 5, 7, 10, 14, 21, and 28 after the procedure(s). Retinal changes were recorded. As a result, 10 RRDs were successfully established in group I. Direct and indirect ophthalmoscopy and fundus photography demonstrated typical features of RRD. No RRD developed in group II and III. It was concluded that the experimental rhegmatogenous retinal detachment produced in a rabbit model after vitrectomy with retinotomy in this study was a convenient and reliable one. This RRD model mimicked the typical pathophysiological changes in humans.
