METHODS One hundred and twenty patients with HLD were divided into 2 groups. Group A ( n =60) received Suc 750mg , po. bid. Group B ( n =60) received Pen 250mg , po. qid. The period of maintenance treatment varied from 6 months to 3 years, averaging 1 5 years. Symptoms and therapeutic effects were evaluated by modified Goldstein scale. RESULTS The total effectiveness of group A in two different periods of treatment were 80% and 85% respectively, higher than those of group B (58% and 59% respectively) ( P <0 05). Suc also had obvious curative effects for the patients who failed in the use of Pen. There were fewer side effect in group A than in group B ( P <0 05). Suc and Pen could increase urinary copper excretion effectively and continually. CONCLUSION Suc is more effective and safer than Pen. Clinically, it can replace Pen as first choice drug for long term maintenance therapy of HLD.展开更多

In complete responders, interferon alfa-2a was administered for further 6 months at the same dose used before as monotherapy.RESULTS Seven (20.6%) of 34 non-responders stopped the combined therapy due to adverse events, including two patients with histological and clinical Child A cirrhosis. In 17/27 (63%)non-responders, the combined therapy was stopped after three months because of non-response. Ten of the 27 non-responders completed the 1;2-month treatment course. At a mean follow up of 28 months (16- 37 months)after the treatment, 4/10 (15%) previous non-responders still remained complete responders,All 13 previous relapsers completed the 12-month treatment course. At a mean follow up of 22months (9 - 36 months) after treatment, 6/13(46%) the previous relapsers were stillsustained complete responders.CONCLUSION Our treatment schedule of the combined therapy for 6 months of interferon alfa2a with a low dose of ribavirin (10 mg/kg/day)followed by 6 months of interferon alfa-2amonotherapy is able to induce a sustainedcomplete response rate in 15% of non-responders and 46% of relapsers with chronic hepatitis C virus-related liver diseases comparable to those obtained with the standarddoses of ribavirin 1000 - 1200 mg/day.Randomized prospective controlled trials using lower total amounts of ribavirin in combination with interferon should be performed.展开更多

Patients were randomly assigned to receive either MBZ [200 mg taken three times per day GRID） （n = 61）] or QC [2 mg/kg bodyweight tid （n = 61）], both for five days. Follow-up faecal samples were obtained at 3, 5 and 7 d after the end of the treatment.RESULTS： Although the frequency of cure was higher for QC （83.6%） than for MBZ （78.7%）, the difference was not statistically significant （P 〉 0.05）. Adverse events were reported more in the QC group （P 〈 0.05）, all of them transient and self-limiting.CONCLUSION： Despite final cure rates ocurring lower than expected, the overall results of this study reconfirmed the efficacy of MBZ in giardiasis and also indicate that, although comparable to QC, at least in this setting the 5 d course of MBZ did not appear to improve the cure rates in this intestinal parasitic infection.展开更多

Neonate mice were orally infected with 50 μLrotavirus suspension (4 × l0s PFU/mL) and treated with ORS or oral liquid of QWBZP, respectively.``RESULTS Eighty-three cases of rotaviral gastroenteritis treated with QWBZP revealed a better efficacy than that treated with ORS (x2 - 10.8T, P<0.05). The contents of sodium and glucose as well as number of patients with positive human rotavirus antigen in stool in QWBZP group were all less than that in ORS group. In animal models,QWBZP was found effective in treating rotavirus gastroenteritis in neonate NIH mice, as compared with control groups. In QWBZP group, the mortality of infected mice was decreased by 73.3%, the body weight of infected mice was increased, the contents of sodium and glucose as well as number of mice with positive rotavirus antigen in feces were significantly reduced, and the pathological changes such as damage of small intestinal mucosa and villi were also obviously alleviated.``CONCLUSION QWBZP has effects on improving the absorptive function of small intestine, shortening the duration of diarrhea and rotavirus shedding from stool and alleviating the pathological changes of small intestine induced by rotavirus.展开更多
