ABSTRACT
In order to promote the standardization of traditional medicines in Laos， China and Laos jointly formed a census team to conduct resource survey， market survey， species identification and others of medicinal plants in Laos. According to the principles of nationality， tradition， effectiveness and commonness， 160 medicinal materials and 40 prescriptions were selected and collected into Lao Herbal Pharmacopoeia after recommendation， examination of experts and review by the established expert committee. Moreover， quality standards of traditional medicine and scientific and clear translation methods were formulated in line with the national conditions of Laos， and the contents were finally compiled according to the 2010 edition of Chinese Pharmacopoeia. The promulgation and implementation of Lao Herbal Pharmacopoeia is a successful example of cooperation in the field of health care between China and Laos， which is conducive to promoting mutually beneficial cooperation between China and Association of Southeast Asian Nations （ASEAN） countries in the field of traditional medicine， and making traditional medicine play a greater role in the medical and health services of ASEAN countries.
ABSTRACT
Objective To investigate the relationship between hepatitis B virus (HBV)deoxyribonucleic acid (DNA) and HBV covalently closed circular DNA (cccDNA) in the ovary and HBV intrauterine infection.Methods HBV DNA and HBV cccDNA were assayed in the ovaries of 33 pregnant women who were positive for HBV DNA,tested by Fluorescent quantitative polymerase chain reaction (FQ-PCR).The level of HBV mark (HBVM) and the content of HBV DNA in peripheral blood of infants were measured by chemoluminescence and FQ-PCR methods respectively.Results The overall positive rate for both HBV DNA and HBV cccDNA in ovarian samples was 51.52％ (17/33).The rate on intrauterine infection among infants was 12.12％ (4/33) and all the 4 infected infants were delivered from mothers with normal hepatic function.When HBV DNA and HBV cccDNA were both positive,the rate of intrauterine infection in infants was significantly higher than those who were with both negative results (P＜0.05).Levels of HBV cccDNA and the rate of positive samples were significantly higher in mothers with infants who appeared to have had intrauterine infection than those did not (P＜0.01 and ＜0.05,respectively).Conclusion HBV infection could be discovered in the human ovary and might be transmitted to the filial generation via ovum.
ABSTRACT
<p><b>OBJECTIVE</b>To analyze the efficacy and safety of bicyclol combined with thymosin in treatment of chronic viral hepatitis B (CHB).</p><p><b>METHODS</b>A total of 135 patients with CHB were randomized into experimental group and control group. The patients in the experimental group received bicyclol orally 75 mg daily and thymosin 20 mg intramuscular injection once every 2 days for 24 weeks and those in control group received bicyclol orally 75 mg daily alone for 24 weeks. The levels of serum aminotransferase (ALT/AST), HBV-DNA, HBeAg /antiHBe were observed.</p><p><b>RESULTS</b>Compared with pre-treatment levels, the serum aminotransferase levels decreased significantly in both groups, but there were no statistically significant differences between them. HBeAg negative conversion rate was significantly higher in the experimental group than in the control group (35.3 percent vs.19.4 percent, P less than 0.05). HBV DNA negative conversion rate was significantly higher in the experimental group than in the control group (36.7 percent vs. 20.9 percent, P less than 0.05). No obvious adverse events which were probably related to the drugs were observed in this study.</p><p><b>CONCLUSION</b>The combination of bicyclol with thymosin had better effect in treatment of chronic hepatitis B ias compared with bicyvlol alone.</p>
