Objective To investigate the clinical effect of IFNα combined with mannan peptide in treatment of patients with HBeAg-positive chronic hepatitis B ( CHB ). Methods Eighty HBeAg-positive CHB patients with HBV DNA quantity ranging from 10 to 10 eopies/mL were enrolled and randomized into the treatment group and the control group ( n = 40 for each ). Patients in treatment group were given daily subcutaneous injection of IFNα-2b 5,000,000 U for 52 weeks, and received mannan peptide 10 mg per intravenous injection or 2. 5 mg per intramuscular injection for a total of 2 to 3 treatment courses (12 weeks for each). The control group received only IFNα-2b treatment. Liver function, serum markers of hepatitis B, HBV DNA quantity and blood tests were performed before the treatment and at 2, 4, 8, 16, 26 and 52-week during the treatment; and the adverse effects were recorded. Results The rates for ALT normalization, negative HBsAg, negative HBeAg, HBeAg seroconversion and negative HBV DNA were 91. 8% , 17. 5% , 52. 5% , 27. 5 % and 47. 5% at 52nd week in the treatment group, while those in the control group were 80. 0% , 12. 5% , 30. 0% , 10. 0 % and 25. 0% , respectively. There were significant differences in HBeAg-negative, HBeAg-seroeonversion and HBV DNA-negative rates between two groups (χ2 = 4. 178, 4.021 and 4.381, P < 0. 05 ) , and these indexes in the treatment group were increased to 57. 5% , 30. 0% and 50. 0 respectively at 52nd week after drug withdraw. White blood cells began to be elevated at 4th week and were restored to the normal levels at 8th week in the treatment group, while the count in the control was lower than the normal value even at 52nd week of the treatment with the average of (3.45±1. 18)×109/L. Conclusion Alpha-interferon combined with mannan peptide therapy is effective for patients with HBeAg-positive CHB, which may restore the declined peripheral WBC counts induced by interferon and improve the compliance.

To explore a new method for identification of Mongolian patent medicine (MPM) by PCR amplification of specific alleles. Eight kinds of MPM were used to study the identification of "Digeda" raw materials. The total DNA of Lomatogonium rotatum and Corydalis bungeana samples were extracted through modified CTAB method, psbA-trnH sequence was amplified by PCR and sequenced directionally. Specific primer was designed. The DNA of 8 kinds of MPM also was extracted and purified by the commercial DNA purification kits. The rbcL and two pair of specific primers sequences were amplified. The specific amplified products were sequenced in forward directions. All specific sequences were aligned and were analyzed. The results indicated that L rotatum can be identified by specific primers from Digeda-4 Tang, Digeda-8 San, Digeda-4 San, and C. bungeana medicinal materials can be identified by specific primers from Li Dan Ba Wei San, Yi He Ha Ri-12 and A Ga Ri-35. PCR amplification of specific alleles can stably and accurately distinguish raw medicinal materials in MPM.

OBJECTIVETo evaluate the efficacy and safety of ambroxol in the prevention of respiratory distress syndrome (RDS) in preterm infants.
METHODSElectronic searches were performed in the Cochrane Library, PubMED, EMBASE, Chinese CBM, Chinese VIP Database, Chinese Wanfang Database and Chinese CNKI Database up to the year of 2009 for randomized controlled trials (RCT) on ambroxol for the prevention of RDS in preterm infants. The meeting articles related to the RCT were manually searched in Pediatrics and Pediatric Research. Meta analysis was performed for the results of homogeneous studies by the Cochrane Collaboration's software RevMan 5.0.17.
RESULTSSix RCTs involving 823 preterm infants were included, and the quality assessment for the trials demonstrated 1 article as A class, 1 article as B class and 4 articles as C class. The Meta analysis showed that ambroxol administration significantly reduced the incidence of RDS (OR=0.24, 95%CI: 0.15 - 0.64, P<0.01), bronchopulmonary dysplasis (BPD, OR=0.41, 95%CI: 0.23 - 0.75, P<0.01), intraventricular hemorrhage (IVH, OR=0.39, 95%CI:0.24 - 0.64, P<0.01), patent ductus arteriosus (PDA, OR=0.33, 95%CI: 0.17 - 0.67, P<0.01) and pulmonary infection (OR=0.24, 95%CI:0.14 - 0.38, P<0.01). No adverse events related to the ambroxol treatment were reported.
CONCLUSIONSThe current evidence shows that early use of ambroxol can reduce the risk of RDS, BPD, IVH, PDA and pulmonary infection in preterm infants.
