Aim To evaluate the effect and safety of azithromycin injection produced in China and cefazolin in the treatment of respiratory tract infections.Methods 50 patients with respiratory tract infections were divided randomly into two groups. Patients in the test group recieved azithromycin in the dosage of 250 mg?d-1,qd for 5 d iv with double dosages at the first time and patients in the control group recieved cefazolin in the dosage of 2.0 g,bid,iv for 5～10 d. Results No statistical significant differences of overall clinical effect were observed between two groups .The fully recovery,effective and side reaction rates for the test group were 46.67%,90% and 3.3%,respectively,and for control group the data were 60%,95%,and 0%, respectively.Conclusion Azithromycin injection produced in China is effective and safe in the treatment of respiratory infections.

OBJECTIVETo investigate the prevalence and subtype distribution of human papillomavirus (HPV) infection and its correlation with age among women in Beijing urban area, and provide some epidemiological evidence for the clinical application of HPV vaccines.

METHODSWe collected cervical specimens from 1999 women in the Outpatient Department of our hospital, performed genetyping of HPV-DNA, and analyzed the incidence of HPV infection in different age groups.

RESULTSHPV infection was detected in 502 (25.2%) of the 1999 women patients, with 391 (19.6%) cases of high-risk HPV, which included 326 (83.4%, 326/391) cases of single infection. HPV-16 was the most common type (21.2%, 69/326), followed by HPV-52 (19.3%, 63/326) and HPV-58 (16.0%, 52/326). The prevalence of HPV infection was the highest among the women aged 41 -50 years and the lowest among those over 60 years.

CONCLUSIONThe subtype- and age-specific distribution of HPV infection among women in Beijing urban area shows an obvious heterogeneity, which deserves due consideration in the clinical application of HPV vaccines.

The yeast fusant ZFF-28, which is high in biomass production and rich in selenium, was constructed after mutagenesis and protoplasts fusion between yeast strains. The total selenium content of ZFF-28 is 1.8 and 1.0 times higher than that of the parental strains Saccharomyces cerevisiae ZY-67 and Saccharomyces kluyveri SZY-198 respectively. Using single factor tests and a L16(4(3) x 2(1)) orthogonal design, the cultivation conditions was optimized as: 50mL culture in 250mL shake flasks in molasses containing 6% sugar and 60microg/mL Se at 28 degree C for 25h at 220 r/min, with the initial pH adjusted to 6.0 - 6.5. Under the optimized conditions, the biomass (dry weight) reached 8.2g/L and the Se content of the cells reached 2050microg/g, with organic and inorganic Se contents being 91% and 9% respectively.

OBJECTIVETo explore the prevalence of syphilis and risk factors on pregnant women in Fujian province.

METHODSFrom July 1st, 2004 to June 30th, 2006, epidemiologic methods as questionnaires to fill in and rapid plasma reagent testing (RPR) were performed. Pregnant women with positive RPR test and then were confirmed by treponema pallidum test (TP). Intervention was provided to the pregnant women who were followed up to the postpartum periods. Results were compared during the peri-neonatal stage between syphilis-infected and non-infected women. Factors which were relative to syphilis infection were analyzed by simple and then further logistic regression analysis.

RESULTSThere were 38 418 pregnant women under study, of whom 772 were confirmed including 60 who were still pregnant. The prevalence of syphilis during pregnancy was 1.85% (712/38 418), with mostly underlying syphilis which played an important role during the neonatal stage. Main risk factors to have been found as: women's occupation, cultural background, place of living, husband's occupation, family income, having sexually transmitted disease(STD) infection. The prognosis of peri-neonatal stage was worse if the mother was having blood RPR test positive. Mortality of peri-neonatal, preterm birth rate and low-birth weight rate were found also higher among mothers when RPR was positive (P < 0.01).

CONCLUSIONThe prevalence of syphilis in Fujian province was going up yearly. 8 factors including women's occupation, cultural background, place of living, received poor health education, having multiple sexual partners, husband's occupation, family income and having STD were main risk factors in the province, the mother's status of syphilis infection would strongly relate to the peri-neonatal stage of pregnancy.

Objective To explore the maternal-fetal transmission patterns and interventional methods of syphilis during pregnancy.Methods A total of 847 cases of syphilis in pregnancy confirmed by rapid plasma reagin test(RPR)and treponema pallidum hemoagglutination test(TPHA)were treated with procaine benzylpenieillin intramuscular injection,and with erythrocin oral medication if hypersensitive to benzylpenicillin.Eight hundred forty seven cases of syphilis during pregnancy were followed up for pregnancy outcomes.And their newborn babies were tested using the RPR.The newborns with positive results were given intervention and followed up until 24 months after birth.Results(1)A total of 733 cases among the total 847 have given birth to living-babies,in which 626 cases were tested using RPR,and the positive rate was 55.1%(345/626).(2)The RPR positive rate,neonatal mortality,preterm birth rate and low birth rate in the newborn of mothers with an RPR titer higher than or at 1:8 were higher than those of mothers with an RPR titer lower than 1:8(P

Objective To evaluate the effect of Astragalus injection on serum SOD and MDA in patients during supratentorial tumor resection. Methods Twenty-four patients with ASAⅠorⅡ degree, aged 20~55 years old, undergoing supratentorial tumor resection were randomized into the control group (group C) and the Astragalus group (group R), with 12 cases in each group. Patients in group R received 250 mL 0.9% sodium chloride in addition with 20 mL Astragalus injection. Patients in group C received the same amount of 0.9%sodium chloride. Blood samples were taken from jugular venous bulb before induction of anesthesia (T1), intubation (T2), open dura instantly (T3), 1 h after the dura opened (T4), 24 h after the dura opened (T5), and 48 h after the dura opened (T6). The levels of serum SOD and MDA were determined. Results The serum SOD in both group R and group C was lower at T3~6 than that at T1 , but the serum SOD in group R reduced significantly compared with group C (P < 0.05); The serum MDA in both group R and group C at T4~6 was higher than that at T1, but the serum MDA in group R increased significantly compared with group C (P <0.05). Conclusion Astragalus injection can enhance the serum SOD activity and reduce MDA output in patients during supratentorial tumor resection.

Self-cloning is a favorable technique in modification of industrial microorganisms especially food microorganisms because of its bio-safety. A survey and outlook of research in breeding of self-cloning industrial brewing yeast were introduced in this study.

· AIM: To study the clinical characteristics of metastatic bacterial endophthalmitis.endophthalmitis were retrospectively studied.manifestation was found in 17 cases (77%), iridal purulent nodules in 2 cases and retinal purulent embolism In 3 cases. The total number of leucocytes and neutrophilic granulocytes was elevated markedly, while lymphocyte count was reduced significantly in early stage. Positive rate of bacterial cultivation was 36%.dophthalmitis often have apparent extraocular infected situation before eye Is involved. Ocular appearance and laboratory examination have some specificity in early stage, while bacterial cultivation, as a golden standard,needs to be further improved.
