Objective A method was established for genotyping of hepatitis B virus (HBV),based on the restriction fragment length polymorphism(RFLP)created by BsrI, StyI,DpnI and HpaII action on an amplified segment of the S region. Methods 223 full-genomic sequences were analyzed and the aligned nucleotide and amino acid sequences of S gene, genotype specific regions were identified by the restriction enzymes, BsrI, StyI,DpnI and HpaII. Pre S PCR-RFLP genotyping method was applied to a number of serum samples from hepatitis B e antigen (HBeAg) positive and negative Chinese chronic HBV carriers. And in 90 samples the following genotypes were observed: 30B, 30 C, 30D. The method using S gene PCR-RFLP was confirmed to be correct by these 90 samples. Three samples of each genotype B, C and D were randomly selected and directly sequenced their S gene to confirm that HBV S gene PCR-RFLP genotyping method was correct disectly. Results The results of two PCR-RFLP HBV genotyping methods were coincide with that of S gene sequence. Conclusions The method for genotyping of hepatitis B virus (HBV), based on S gene RFLP is established to be highly sensitive, differential and accurate. The RFLP patterns are easy to be recognized because of its simplicity and singleness.

Objective To explore the relationship between hepatitis B virus (HBV) genotype and outcome of HBV infection. Methods PCR amplification of HBV small S gene in combination with a restriction fragment length polymorphism (RFLP) analysis was applied to identify HBV genotype in the serum samples of 80 asymptomatic HBV carriers (AsC group) and 120 liver cirrhosis patients with HBV infection (LC group) in Gangdong province of China. Results The frequency of HBV genotypes B, C and D in AsC group was 45% (37/80), 33.75%(26/80) and 21.25%(17/80)respectively, and that of HBV genotypes B, C and D in LC group was 32.5%(39/120), 65.8%(79/120) and 1.6%(2/120) respectively. There is no HBV genotypes A, E and F in this series. The distribution of HBV genotypes in the two groups was not significant correlation with the state of HBeAg. There was a significant difference in the distribution of HBV genotypes between the two groups (P

Objective To investigate the expression of mRNAs for cholesterol side chain cleavage enzyme (p450 scc), 17?-hydroxylase / C17-20 lyase (P450 C17) and 3?-hydroxysteroid dehydrogenase (3?-HSD) in frontal cortex, amygdala, hippocampus, striatum and midbrain of morphine dependence rats.Methods Twenty-one male SD rats were randomly divided into 3 groups with 7 animals in each group: (1) control group (group C) ; (2) morphine dependence group (group D) and (3) morphine withdrawal group (group W). In group D and W the animals were given intraperitoneally increasing doses of morphine starting from 5 mg?kg-1 to 10, 15, 20, 30, 40 and 50 mg?kg-1 twice a day for 7 days. In group C the animals were given normal saline instead of morphine. In group C and D the animals were decapitated 1 h after last injection. In group W naloxone 2 mg?kg-1 was given 1h after last morphine injection, then the animals were decapitated 30 min after withdrawal symptoms were observed. The brains were immediately removed and the frontal cortex, amygdala, hippocampus, striatum and midbrain were separated. The expression of mRNAs for the three steroidogenic enzymes in the different brain regions of rats were determined by RT-PCR.Results The expression of P450scc mRNA in striatum and 3?-HSD mRNA in amygdala, striatum and frontal cortex decreased in group D compared with group C. The expression of 3?-HSD mRNA increased in morphine withdrawal group compared with group D.Conclusion The gene expression of steroidogenic enzymes decreases in some brain regions of morphine dependence rats, suggesting that endogenous neurosteroids might be involved in morphine dependence.

Objective To compare the effects and cost of peripheral intravenous catheter (PIV) and peripherally inserted central catheter (PICC) on very low birth weight infants (VLBWI).Methods From July 2013 to August 2015,95 VLBWI with PICC (PICC group) and 90 VLBWI with PIV (PIV group) admitted to the Neonatal Intensive Care Unit (NICU) of Changzhi Maternal and Child Care Hospital were included in the analysis.The two groups were compared in body mass increase,average length of hospital stay,incidence of catheter-related complications,and care cost and effect.Results The body mass increase per weak was higher in the PICC group than in the PIV group,with statistically significant difference (P ＜ 0.05).The average length of hospital stay in the PICC group was shorter than that in the PIV group [(48.2 ± 5.2) d vs.(53.2 ± 8.1) d,P ＜ 0.05].The incidence of catheter-related complications was lower in the PICC group than in the PIV group (35.4％ vs.44.9％),including phlebitis (PICC group,21 person-times;PIV group,169 person-times),liquid leakage or exosmose (PICC group,2 person-times;PIV group,185 person-times),and catheter prolapse (PICC group,3 person-times;PIV group,145 person-times) with statistically significant differences (all P ＜ 0.05),and catheter blockage (PICC group,7 person-times;PIV group,84 person-times) and other complications such as venous embolism and infection (PICC group,1 person-time;PIV group,3 person-times) with no statistically significant differences (all P ＞ 0.05).The average monthly cost in the PICC group (1 951.5 yuan) was lower than that in the PIV group (2 008.5 yuan),and the cost of single insertion in the PICC group (1 691.5 yuan) was higher than that in the PIV group (129.9 yuan),the cost-effectiveness was better in the PICC group than in the PIV group (30.22 vs.36.45).Conclusions For VLBWI,PICC can reduce the times of venous puncture,the incidence of complications,and promote body mass increase.However,the monthly cost was similar between the two groups in this study,possibly because of the short-time of this study.The advantages in cost-effectiveness of PICC may become more prominent when the catheter dwelling time extends.

The implementation of cancer genome scientific program has promoted the diagnosis, prevention and tar-get treatment of diseases at molecular level with massive cancer genome data accumulated. Effective mining and use of cancer genome data have thus become the focus in the field of cancer genome. The cancer genome was annotated and demonstrated according to the mining of high-throughput cancer genome data from American National Cancer Research Center, namely the disease-named entity and drug-named entity were identified from the gene function descriptive text and the mined high-throughput data were annotated from their clinical application, in order to help scientific workers to find the relationship between diseases, drugs and genes in scientific literature.

Objective To study the possibility of the exist of specific antibody against platelet in tumor patients and to evaluate the value of MAIPA in measure of specific antibody against platelet in malignant tumor patients with nonimmune thrombocytopenic purpura. Methods Anti- GPⅡb/Ⅲa and anti- GPⅠb/Ⅸ autoantibodies were detected by a modified monoclonal antibody immobilization of platelet antigens assay(modified MAIPA). Results The positive rate of the platelet antibody in nonimmune thrombocytopenic purpura is very low with MAIPA. Conclusions The platelet GP- specific autoantibody detection is considerably important in discriminating immune from nonimmune thrombocytopenia.

Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases. However, due to its complex pathogenesis, there are no officially approved drugs for NAFLD treatment currently. Therefore, it is extremely urgent to find safe and effective anti-NAFLD drugs. Nowadays, lipid-lowering drugs are the main option for NAFLD therapy, but the clinical efficacy of chemical drugs is also very limited, as well as the frequent side effects or adverse reactions. Traditional Chinese medicine (TCM) has attracted more and more attention in the treatment of NAFLD due to its unique advantages through multiple targets and pathways with few side effects. In recent years, numerous studies have demonstrated that the imbalance of gut microbiota plays an important role in the occurrence and development of NAFLD. This review systematically summarizes the experimental and clinical evidences of TCM active compounds and TCM prescription involved in the regulation of intestinal flora in the treatment of NAFLD in recent years, so as to provide a reference for further exploring the pathogenesis of NAFLD and exploring TCM treatment methods.
