Objective To analyze the distribution and clinical characters of cyanotic congenital heart diseases in newborns.Method We examined the suspicious cases with color doppler ultrasonic cardiogram(CFM),and compared with the results of autopsies.Results The most common congenital diseases in the group were complete transposition of the great arteries,with the proportion of 34.4%, and most of them were compounded cardiovascular disorders. The most common symptom was cyanosis, took the proportion of 84.3%; some patients had no cyanosis, tachypnea and murmurs.The cases with cardiovascular disorders most were combined with type Ⅱrespiratory failure and metabolic acidosis.Conclusions There are many types of congenital heart diseases, the symptoms are untypical,so the suspicious cases shall examine with CFM as early as possible.

Objective To clone,express,and purify Tp 0319 outer membrane protein of Treponema pallidum and to develop an indirect ELISA for diagnosing syphilis.Methods The expression plasmid PQE32/Tp 0319 was conventionally constructed.The recombinant Tp 0319 protein was produced in E.coli M15 after induction by IPTG.The Tp 0319 protein was analyzed by SDS-PAGE and Western blotting,and then purified with Ni-NTA affinity chromatography.Indirect ELISA was developed to detect the syphilis antibody in human sera.Results The recombinant plasmid PQE32/Tp 0319 was constructed successfully and the fusion protein with relative molecular weight near 30 000 Dalton was revealed by SDS-PAGE.Western blotting proved that the recombinant protein specifically reacted with anti-Tp antibodies in sera from syphilis patients.The results of the indirect ELISA indicated the sensitivity and the specificity were both 100%.The concordance of 300 sera(150 from blood donors and 150 from syphilis patients)detected in parallel by the ELISA and the TPPA was 95.3%.Conclusions The data suggest that the prepared recombinant protein Tp 0319 of Treponema pallidum has high immunoreactivity.The recombinant protein can be used to develop ELISA kit for diagnosing syphilis.

ObjectiveTo determine whether antibiotic prophylaxis can reduce the risk of postoperative infective complications in men undergoing transrectal prostatic biopsy (TPB) who had sterile preoperative urine.MethodsMEDLINE, EMBASE, Cochrane Collaboration Reviews, Chinese Medical Current Contents (CMCC), and National Knowledge Infrastructure (CNKI) were searched for rando-mized controlled trials that compared the effect of antibiotic prophylaxis with placebo or active controls for men undergoing TPB with preoperative sterile urine. Two reviewers independently extracted the data of patient characteristics and outcomes based on a prospectively developed protocol.ResultsA total of 12 trials (3 placebo controlled, 3 non-treatment controlled, and 6 activly controlled) involving 1 987 patients, met the inclusion criteria. Prophylactic antibiotic use in patients at low risk undergoing TPB significantly decreased bacteriuria and middle degree fever incidence, but could not decrease the incidence of bacteremia. The relative risk for post-TPB bacteriuria, middle degree fever, and bacteremia were 0.32 (95% CI 0.23 to 0.46), 0.37 (95% CI 0.17 to 0.77), and 0.96 (95% CI 0.61 to 1.50), respectively. Effective antibiotic classes included quinolone, co-quinolone and nitroimidazole, and co-trimethoprim and sulfamethoxazole. Treatment protocols of any duration were effective.ConclusionAntibiotic prophylaxis obviously decreases the incidence of bacteriuria and middle degree fever but not bacteremia in men with preoperative sterile urine undergoing TPB. A significant decrease in bacteriuria incidence can be achieved with a range of antibiotic agents, including quinolones and co-quinolone and nitroimidazole. Treatment protocols of any duration are effective with no heterogeneity.

Objective To evaluate the value of prenatal ultrasound in the interrupted aortic arch (IAA), and analyze the reasons of misdiagnosis and improve diagnostic ratio of this kind of defects. Methods Ultrasonic characteristics were analyzed in 16 fetuses with aortic arch anomalies, which were compared with ultrasound image and autopsy results of the normal fetus. The relativity of fetal IAA and abnormal chromosome was also analyzed. Results Among the 16 cases, 15 cases were confirmed by anatomy and the accuracy of ultrasound diagnosis was 94% (15/16), of which one case was serious constriction of aortic arch, one case was error type, three cases were obtained explicit type due to unsatisfactory results of prenatal ultrasound. The coincidence rate of ultrasonic type was 73% (11/15). All of the corrected diagnosed cases were detected with ventricular septal, of which 5 cases were detected with complete endocardial cushion defect, 9 cases were found extra cardiac malformations. Among the 7 karyotype check cases, 3 cases were diagnosed with Trisomy 18, 1 case Trisomy 13, while the rest 3 cases normal. The incidence rate of Trisomy 18 was 43 % (3/7). Conclusions Prenatal ultrasound shows a high accuracy in diagnosing fetal interrupted aortic arch (IAA ), but there’s a need to be improved in explicit typing. It is difficult to identify fetal interrupted aortic arch (IAA) and serious constriction of aortic arch (COA). The incidence rate of Trisomy 18 in the abnormal chromosome of fetal IAA is high.

Objective To investigate the effect of aurora kinase inhibitor VX-680 on cell apoptosis and Bcl-2 expressions in human bladder cancer T24 cells. Methods T24 cells were cultured and treated with VX-680 at various concentrations and time points in vitro. VX-680-induced apoptosis of T24 cells was calculated by flow cytometry. The morphological change of treated cells was observed by microscopy;Bcl-2 mRNA and protein expression in T24 cells was detected by RT-PCR and Western blot assay , respectively. Results The apoptosis rate of VX-680-induced T24 cells increased in a dose-and time-dependent manner. The increase of apoptosis rate and decrease of Bcl-2 mRNA and protein expression in VX-680-induced T24 cells were in a dose-dependent manner. Conclusion VX-680 can significantly induce the apoptosis of T24 cells by down-regulating Bcl-2expression in a dose-dependent manner.

Objective To explore the possible mechanisms of Arsenic Trioxide in treating rheumatoid arthritis(RA)by observing the changes of HE staining and NF-KB expression as well as the apoptosis of syn- oviocytes in adjuvant-induced arthritis rats.Methods After the animal model was set up on Wistar rats sue- cessfully,they were randomly divided into AA model group and arsenic trioxide treatment group.The treat- ment group were injected with 4 mg'kg~(-1)9?d~(-1)arsenic trioxid fluid for 7 days.All of the rats were killed 3 days after the complete of injections.The joint specimens were exposed,fixed,decalcified,wrapped and cut into slices.All slices were examined by HE stain and immunohistological evaluation.Results HE staining showed that when compared with the normal control group,the layers of synoviocytes of the AA group were increased to 6-8,and the arrangement of synoviocytes was disordered and heavy inflammatory cell infiltration were found in the AA group.In the arsenic trioxide treatment group,the layers of synoviocytes increased to 3～4,and medi- um amount of inflammatory cell infiltration were found.The intensity of synovial NF-kB(p65)positive stain in AA model group was significantly higher than that in the normal control group.The synovial expression and ac- tivation of NF-kB in the treatment group were decreased markedly,and did not return to normal level.The average gray scale calculation showed that there were significant differences between the three groups(P

A new wood-degrading fungus Monodictys asperospera(Cooke & Massee) Ellis with a high level of laccase production was chosen to study.This laccase was purified by ammonium sulfate precipitation,DEAE-cellulose and sephacryl S-300.Purification of about 8.1 fold was achieved with an overall yield of 5.7%.Its molecular weight was estimated to be about 77 kD.The optimum temperature and pH of the lac-case activity were 55?C and 6.0,respectively.Kinetic studies of the laccase showed that the Km and the Vmax for using syringaldazine as substrate was 0.163 mmol/L and 0.194 mmol/(L.min),respectively.The carbo-hydrate content was 18.14%.In addition,it was found that laccase activity was significantly inhibited by Cu2+.

Objective To explore the relationship between pulse wave velocity(PWV)and blood pressure classification and cardiovascular risk factors stratification in patients with essential hypertension. Methods Totally,390 patients with essential hypertension were recruited in the study and their carotid- femoral PWVs were recorded by an automatic pulse wave velocity measurement system.The patients were stratified by their cardiovascular risk factors.PWVs were compared between patients with varied blood pressures or with and without cardiovascular risk factors.Results There was no significant difference in PWV between patients of phase 1 and phase 2 hypertension,[(10.8?1.7)m/s vs.(11.9?1.2)m/s,P =0.398].PWV in patients with more than one risk factor was significantly higher than that in those with hypertension alone,[(10.4?1.4)m/s vs.(11.7?1.4)m/s,P=0.018].Conclusions PWV in hypertensive patients with one or more than one other risk factors was significantly higher than that in those without other risk factors.Cardiovascular risk factor might play a more important role in arterial stiffness.
