LAM was taken by 10 patients with YMDD mutations and its curative effect was observed.RESULTS: Twenty-eight cases (26.9%) had YMDD mutations, of them 11 cases (28.9%) were in familial aggregation group (38 cases) and 17 cases (25.8%) in nonfamilial aggregation group (66 cases) with no significant difference between the two groups. Twenty-seven point one percent (16/59) cases were positive for HBeAg YMDD mutations, and 26.7% (12/45) cases were negative for HBeAg and positive for anti-HBe. There was also no significant difference between the two groups. Different YMDD incidence rate existed in different HBV genotypes.HBV DNA level did not have a positive correlation with the incidence of YMDD mutations. LAM was effective for all patients with mutations.CONCLUSION: Wild mutant strains in HBV and their incidence rate have no significant difference between familial aggregation and non-familial aggregation. It may have no significant relationship between YMDD mutations and pre-c-zone mutations. HBV DNA level may not have a positive correlation with YMDD mutations. LAM is clinically effective for CHB patients with YMDD mutations.展开更多

Two groups of patients were compared, depending on the treatment they have got group, which was taking 75 mg of enteric aspirin per day and the group, where pantoprazole has been added to aspirin in the usual dose. Mucosa assessment was studied using fibrogastroduodenoscopy and Lanza score. Also, the relationship between aggression factors that cause NSAID gastropathy and mucosal protection agents has been studied. It was proved that the pantoprazole influence reduces the ulcerative-erosive lesions amount. Stomach erosive lesions percentage decreased from 58.18% to 42.42%, stomach ulcers from 14.55% to 6.06%, duodenum erosive lesions decreased from 34.55% to 24.24%, duodenum ulcers deceased from 9.09% to 3.03%. A positive correlation between LTB4 and Lanza scale was checked after pantoprazole treatment, indicating an impact on the LTB4 reduction in ulcers healing in patients with NSAID gastropathy.展开更多

This study aimed to corroborate their presumed anti-inflammatory activity, identify their active ingredients and validate their use. The topical anti-inflammatory activity of a commercial partially purified Quillaja saponin aqueous extract （Ultra Dry 100Q, UD）, the crude acid hydrolysate （H-100Q） of this material, its two most abundant sapogenins QA （quillaic acid） and PA （phytolaccagenic acid）, and two formulations containing QA were subjected to topical assays for the inhibition ofmurine ear inflammation elicited by AA （arachidonic acid） or TPA （phorbol ester）. The dose-dependent anti-inflammatory activity of QA was confirmed in both AA （maximal effect 92.1%） and TPA （maximal effect 62.2%） assays, and PA showed significant anti-inflammatory activity against AA （46.5%）. Two dermo pharmaceutical formulations containing 8% w/v QA as the active ingredient--a cream and a gel--also exhibited significant anti-inflammatory effects in the TPA （50.8%） and AA （39.5%） assays.展开更多
