Objective:To discuss the passive immunity effect and mechanism of HBIG injections to matrix to block the mother-to-child vertical transmission of HBV. Methods:94 cases of patients with chronic viral hepatitis were selected and divided into 3 groups randomly. 31 cases of control group were given no HBIG intervention,while 31 cases of baby intervention ( BBI) group were given HBIG injection in 6h of birth,and 32 cases of infant & mom intervention ( IMI) group were given HBIG injection respectively in 28,32,36 weeks of gestation and 6h of birth. Further more,all newborns were vaccinated against hepatitis B in 0,1 and 6 months,after the last vaccination,peripheral blood of the children were extracted and detected for HBV markers,HBV-DNA and immune function. Results:There were significant difference (P<0. 05) in neonatal HBeAg,HBsAg and HBV-DNA positive rate for the three groups,with Control group got the highest while IMI group got the lowest;and there are also significant differences (P<0. 05) HBeAb positive rate,with Control group got the lowest while IMI group got the highest. We also found that the complement (C3,C4) levels and T cell subtypes (CD3+,CD4+,CD8+) count of the three groups of newborns had significant differences too(P<0. 05),with Control group got the lowest while IMI group got the highest;in terms of immunoglobulin,both the IMI and BBI group were higher in IgG and IgM level (P<0. 05), while there was no obvious difference in IgA between groups (P<0. 05). Conclusion:Maternal HBIG injections can effectively activate the maternal humoral immunity and cellular immunity,resulting in the decrease of HBV. It can also improve newborn′s antigen-antibody response and relieve T lymphocytes loss induced by antiviral consumption through placenta,which may play great role in the passive im-munity mechanism of blocking mother-to-fetus transmission.

OBJECTIVE:To probe into the utilization status of carbopenem antibacterials in our hospital.METHODS:The antimicrobial use density(AUD),the antimicrobial average daily cost(AADC),and the antimicrobial cost density(ACD) of carbopenem antibacterials used in our hospital during 2000～2006 were analyzed statistically using DDDs analytical method. RESULTS:DDDs and AUD of the carbopenem antibacterials used in our hospital showed an upward trend;the AADC of each kind was decreasing year by year but ACD presented an upward trend.CONCLUSION:Safe,effective,economical and rational use of carbopenem antibacterials is in the interest of protection of drug resources used for bacterial infection.

OBJECTIVE:To provide reference for the supply of emergency drugs. METHODS:The data of emergency drugs in the inpatients of our hospital were collected from hospital information system during 2012-2016,including the proportion and age of emergency patients,drug,clinical departments and disease types. The trend of emergency drugs was analyzed by using SPSS 16.0 software. RESULTS:The proportion of emergency patients and discharged patients were increasing year by year. The number of patients in <10 year-old and 10-19 year-old showed a declining trend year by year. The number of patients in 30-39 year-old,50-59 year-old and >60 year-old showed an increasing trend year by year. Among emergency drugs,the use frequency of Heparin sodium injection,Dexamethasone sodium phosphate injection and Flumethasone injection showed a declining trend year by year;the use fre-quency of Hemagglutination for injection,Penehyclidine ether injection,Atracurium besylate injection and Propofol injection showed an increasing trend year by year. Among clinical department,the number of pediatric patients showed a declining trend year by year;the number of patients in obstetrics department,emergency department,cardiology department,micro hand surgery department and pediatric surgery department showed an increasing trend year by year. Among emergency disease types,the number of patients with re-spiratory system disease,infectious and parasitic diseases showed a declining trend year by year;the number of patients with circula-tion system disease,injury and poisoning,certain other consequences of external factors,digestive system diseases,pregnancy,child-birth and puerperium disease as well as some cases originated in the perinatal period showed an increasing trend year by year. CON-CLUSIONS:With the change of the proportion,age and disease type of emergency patients,the type and utilization rate of emergen-cy drugs have changed. It is necessary to adopt effective measures to guarantee the supply of emergency drugs.

Objective To produce an experimental information for the safety assessment of Vero cells during subculture. Methods Passage and freeze on Vero cells, and Vero cells in different passages in vitro and in vivo tumorigenicity were tested. The protein expression of different Vero cell passages was analyzed. Results Vero cells passaged to p270 and 14 cell banks were developed and stored for future evaluation. In vitro and in vivo tumorigenicity Lest results of Vero cells in different passages were negative. Conclusion Although the tumorigenicity test results in vitro and in vivo process were negative, the protein expression of more than p200 Vero cells were changed, which produced the experimental reference for the safety evaluation of the process during the Vero cell passage.

Objective To analyze the genotypes distribution and clinical significance of human papillomavir-us(HPV) infection in atypical squamous cells of undetermined significance (ASC-US) ,low squamous intraepi-thelial lesion (LSIL) and high squamous intraepithelial lesion (HSIL) of uterine cervix ,meanwhile to conduct the cervical histopathological diagnostic analysis in the patients with ASC-US、LSIL and HSIL .Methods The gene amplification technique (PCR) combined with gene-chips technology were adopted to conduct the 23 kinds of HPV genotype detection on 236 cases of cervical ASC-US ,36 cases of cervical LSIL and 61 cases of cervical HSIL specimens .All cases of ASC-US ,LSIL and HSIL were performed the cervical biopsy his-topathological diagnosis .And then the subjects related data were analyzed .Results Among 236 cases of cervi-cal ASC-US specimens ,139 cases of HPV infection were detected with the total HPV infection rate 58 .90％(139/236) ,in which the single genotypes infection rate was 38 .14％ (90/236)and the multiple genotypes infec-tion rate was 20 .76％ (49/236);26 cases of HPV infection were detected from 36 cases of cervical LSIL speci-mens with the total HPV infection rate of 72 .22％ (26/36) ,in which the single genotypes infection rate was 52 .78％ (19/36) and the multiple genotypes infection rate was 19 .44％ (7/36);61 cases of HPV infection were detected from 58 cases of cervical HSIL specimens with the total HPV infection rate of 95 .08％ (58/61) , in which the single genotypes infection rate was 68 .85％ (42/61)and the multiple genotypes infection rate was 26 .23％ (16/61) .The total infection rates had statistically significantly differences among the cervical ASC-US group ,LSIL group and HSIL group (P<0 .05) .Conclusion HPV16 ,52 ,58 are the main types in the patients with cervical ASC-US ,LSIL and HSIL .The gene-chip technology can be used in the HPV genotypes detection of cervical cells ,which has an important clinical significance for further distribution management on ASC-US patients and should draw great attention of gynecologist .
