Objective To evaluate the efficacy of long-term lamivudine therapy in patients with decompensated cirrhosis after HBV infection. Methods The clinical courses and outcomes of lamivudine therapy in 60 patients with decompensated cirrhosis were observed and the results were compared with those in historical control group who did not receive lamivudine therapy. Kaplan-Meier method was used to measure the survival rates of two groups. Results There was significant improvement of Child scores in the treatment group, which were 9.4±2.4 at the baseline and 8.3±1.8, 6.5±2.2, 6.3±0.7 at 12 months,24 months and 36 months of the therapy (P<0.01), respectively. Significant clinical improvements were observed in 20 patients in the treatment group, but no improvement was observed in the controls. The rates of serum HBV DNA clearance was 84.7% (50/59), 89.2% (50/56), 76.8% (40/52) and 72%(36/50) at 6 months, 12 months, 24 months and 36 months of the therapy. And the rates of YMDD mutant were 0, 7% (4/56), 17.3% (9/52) and 26% (13/50) at these time points. The survival rates for the treatment group were 77.7%, 50% and 46. 5% at 1 year, 2 year and 3 year, while those in the control group were 71.28%, 45% and 43.5%, the difference was of no statistical significance (P=0.12).Conclusion Lamivudine therapy can significantly improve the liver function in patients with decompensated cirrhosis, but it may not improve the survival of patients.

In recent years,studies have shown that galactose - deficient IgA1(Gd - IgA1)antibodies are im-portant in the pathogenesis of IgA nephropathy(IgAN). Serum levels of Gd - IgA1 antibodies are associated with levels of proteinuria and renal histological grading. Measuring the antibodies has guidance value in the diagnosis of IgAN,for its sensitivity and specificity can be up to 88% - 89% and 89% - 92% respectively. In addition,the antibodies play an important role in clinical prognosis,and it may provide a new direction for treatment in IgAN. Now,its role in prognosis of IgAN was reviewed.

Objective To investigate the effects of desflurane and/or nitric oxide (NO) on the lung injury induced by ischemia-reperfusion ( I/R) during cardiopulmonary bypass (CPB) in children with pulmonary hypertension secondary to congenital heart disease (CHD) .Methods Forty children with CHD and pulmonary hypertension (24 male, 16 female) aged 0.6-3.7 yrs weighing 7.1-11.9 kg undergoing cardiac surgery under CPB were randomly divided into 4 groups ( n = 10 each): group control; group DES; group NO and group DES + NO. The patients were premedicated with oral midazolam 0.5 mg?kg-1. Anesthesia was induced and maintained with fentanyl and vecuronium. Radial artery was cannulated for MAP monitoring and blood sampling. Pulmonary catheter was placed under direct vision after chest was opened. The patients received inhalation of desflurane (1-1.3 MAC) (group DES)/NO (10-20 ppm) (group NO) /DES + NO (group DES + NO) immediately after pulmonary catheterization until the start of CPB. MAP, PAP, peak airway pressure (Ppeak) and compliance of respiratory system (Crs) were recorded at 5 min after induction (T0 ), 5 min before CPB (T1 ), 5 min after start of CPB (T2) and at the end of surgery (T3) . Blood samples were taken at T0 and T3 for determination of methemoglobin (Met-Hb), soluble intercellular adhesion molecule-1 (sICAM-1), XOD and MDA.Results The four groups were comparable with respect to age, M/F ratio, body weight, duration of CPB and type of operation performed. MAP was significantly decreased after inhalation of desflurane alone or desflurane + NO before CPB ( at T1) as compared to the baseline value at T0; while PAP was significantly decreased after inhalation of NO alone or NO+ desflurane before CPB (at T1) as compared to the baseline value. Ppeak was significantly lower while Crs was significantly higher at end of surgery (T3) in group NO and NO + desflurane than in control group. Blood sICAM-1 and MDA concentrations and XOD activity were significantly lower at the end of surgery (T3 ) in group DES, NO and DES + NO than in control group. Met-Hb was significantly increased at the end of surgery (T2) as compared to the baseline (T0) in group NO and DES + NO but was still within normal range. Conclusion Inhalation of desflurane and/or NO can ameliorate the lung injury during CPB in children with pulmonary hypertension secondary to CHD, in addition to inhibit the pulmonary hypertension.
