12 months, baseline serum HBV DNA ≥104copies/ml) were prospectively followed. Virological and serologic responses and laboratory data of liver and renal function of each patient enrolled were monitored every three months. Entecavir resistant mutations were detected by direct sequencing of HBV reverse transcriptase region which was amplified by semi-nested polymerase chain reaction (PCR). HBV sequences of different genotypes obtained from GenBank were aligned to identify entecavir drug resistant substitutions. Results Of the 41 lamivudine refractory CHB patients who met the inclusion criteria, 16 patients (39%) achieved the point of undetectability in HBV DNA level (

Objective To explore the clinical value of measuring myoglobin (MYO) for the early diagnosis of ACS and monitoring the effect of thrombolysis. Methods MYO and cTnT, CK、CK-MB were measured. The sensitivity, specificity, positive predicting value and negative predicting value of cTnT and CK-MB at different time points were studied. And the correlation was investigated between the MYO plasma level and the severity of coronary artery lesion according to coronary arteriongraphy. The changes of MYO level with thrombolysis were also observed. Results The concentration of MYO, cTnT, CK, CK-MB in acute myocardial infarction patients were (56?34)?g/L, (0. 05?0. 03 )?g/L,(94?84) U/L,(17?13) U/L respectively, which were higher than that in the healthy controls(P 0. 05). The level of MYO rises to the peak at 5. 26 hours after operating thrombolysis. The peak time was earlier than CK and CK-MB (P

Interventional medicine plays an important role in the diagnosis and treatment of cardiovascular and cerebrovascular diseases, hepatobiliary tumors and other diseases, which has become the third largest type of treatment technology besides internal and surgical treatment. In recent years, with technological breakthroughs in imaging technology, robotic surgical system, artificial intelligence, Internet of Things and other fields, unprecedented opportunities have been provided for interventional/minimally invasive+robotics. Interventional robotic surgical systems have mushroomed around this field. The authors discuss the current status and future of interventional robotic surgical system with high recognition worldwide, especially the three categories of specialized robotic surgical system for vascular intervention, percutaneous puncture intervention and natural non-vascular luminal intervention.

Protein-protein binding is the basis of virus and host cell interactions. With the application of technology of studying protein interactions, more knowledge of replication and pathogenesis of hepatitis C virus (HCV) was acquired. Non-structure protein 5B(NS5B) of HCV is a kind of viral protein, which plays an important role in replication of HCV. However, the effect of NS5B is not clear. To investigate the biological function of NS5B, we performed yeast two hybrid to look for proteins in hepatocytes interacting with NS5B. We constructed NS5B bait plasmid by cloning the gene of NS5B into pGBKT7, then transformed it into yeast AH109(a type). The transformed yeast was mated with yeast Y187(? type)containing liver cDNA library plasmid in 2?YPDA medium. Diploid yeast was plated on synthetic dropout nutrient medium (SD/-Trp-Leu-His-Ade) containing x-?-gal for screening. Thirty-three colonies were selected and sequenced. Among them, two colonies were new genes with unknown function. The preliminary successful cloning of gene of protein interacting with NS5B paved the way for the study of the physiological function of NS5B and its associated protein.

Objective To explore the early diagnostic value of the expression level of plasma N-terminal pro-B-type natriuretic peptide(NT-proBNP)for heart failure(HF)in neonates.Methods Thirty-five neonates who were clinic diagnoses as HF newborns and 20 cases of non-HF newborns(control group)were selected,on the 2nd,the 7th day after birth,plasma NT-proBNP and CK-MB levels were measured with electrochemiluminescence method and mass method.All data were analyzed by SPSS 16.0 software.Results Compared with the control group,CK-MB and NT-proBNP were higher in the HF group before treatment(P0.05).Compared with before treatment,CK-MB and NT-proBNP were significantly lower in the HF group(P0.05),NT-proBNP level was lower in the control group(P

To try to find out the possible use of histochemistry in the prenatal diagnosis in first trimester of pregnancy, 20 kinds of enzymes in chorionic villi from 6th to 9th week of gestation which are related to inborn errors of metabolism were investigated and graded according to their histochemical reactive intensity; the enzymes listed below: (1). ?-glucuronidase, (2). ?-galactosidase, (3). arylsulfatase, (4). ?-N-acetylglucosaminidase, (5). 3?-hydroxysteroid dehydrogenase, (6). NADH dehydrogenase, (7). adenosine triphosphatase, (8). alkaline phosphatase,(9). acid phosphatase, (10). creatine phosphokinase, (11). glutamic dehydrogenase, (12). aldolase, (13). xylitol dehydrogenase, (14). alcohol dehydrogenase, (15). xanthine oxidase, (16). catalase, (17). ornithine carbamoyl transferase, (18). lipase, (19). cholinesterase, (20). ?-glutamyl transpeptidase. The experimental results show that the last 6 kinds of enzymes present negative reactions. Since the his- tochemical reactions of the first 14 kinds of enzymes are positive, it is possible that they can be used for the prenatal diagnosis of inborn errors of metabolism caused by dificiency of corresponding enzymes. The results also show that compared with biochemical method, histochemical method has the advantages of requiring smaller amount of chorionic villi, being without contamination by maternal cells, simplicity and rapidity.
