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 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 discuss the effect of problem-based learning(PBL)model in Neurological history collection.Methods PBL model was performed in Neurological class during the period of novitiation,and estimated by the students.Results PBL model has more advantages in improving autonomous study motivation,and brings up accurate clinical learning method.Con-clusions Compared with the traditional model,PBL model was more suitable for the development of modern medical medicine.

Objective To investigate the clinical efficacy of acupuncture plus ashi point pricking bloodletting in treating acute gouty arthritis.Methods Seventy patients with acute gouty arthritis were randomly allocated to a treatment group of 38 cases and a control group of 32 cases. The treatment group received acupuncture plus ashi point pricking bloodletting and the control group, routine medication. Blood uric acid and C reaction protein contents were measured in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results There were statistically significant differences in blood uric acid and C reaction protein contents after one and two courses of treatment compared with before treatment in the two groups (P<0.01). After two courses of treatment, there was a statistically significant difference in comparing C reaction protein contents between the two groups (P<0.05). The total efficacy rate was 84.2% in the treatment group and 81.3% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Acupuncture plus ashi point pricking bloodletting is an effective way to treat acute gouty arthritis.

BACKGROUND:Because macrophages play an important role in the body’s inflammatory response, the detection of the impact of biological materials on the behavior of macrophages can assess the immunogenicity of materials. OBJECTIVE: To analyze the activation effect of decelularized extracelular matrix materials on macrophages. METHODS: The peritoneal macrophages of BALB/c mouse were obtained and cultured by dividing into five groups. Control group was simple cel culture group, experimental group 1 was acelular matrix membrane material directly contacting with macrophage for culture, experimental group 2 was fresh pericardial material directly contacting with the macrophage for culture, experimental group 3 was acelular matrix membrane material indirectly contacting with macrophages for culture, experimental group 4 was fresh pericardium material indirectly contacting with macrophages for culture. After 24 hours of culture, the secretion of nitric oxide and cytokines in cel culture supernatant was determined. After 48 hours of culture, the absorbance value was determined by MTT method and the toxicity grading was determined. RESULTS AND CONCLUSION: The toxicity grading in experimental groups 1-4 was respectively grades 2, 4, 0, 2. The nitric oxide level in experimental groups 1 and 2 was higher than that in the control group (P < 0.05), and the nitric oxide level in the experimental group 2 was higher than that in the experimental group 1 (P < 0.05). There were no significant differences in interleukin-2, interleukin-4,interferon γ, interleukin-17A and interleukin-10 levels between these five groups. The interleukin-6 level in the experimental group 2 was higher than that in the control group (P < 0.05); The expression levels of tumor necrosis factors in experimental group 1, 2 and 4 were higher than those in the control group (P < 0.05), and experimental group 2 higher than the experimental group 1 (P < 0.05), experimental group 1 higher than the experimental group 4 (P < 0.05). These results show that acelular matrix material can activate macrophages in direct contact.
