OBJECTIVE:To analyze bacterial infection of chronic bacterial prostatitis and to provide reference for clinical therapy. METHODS: Prostatic fluid was collected in sterile condition. Positive results of bacterial culture in 261 cases of chronic bacterial prostatitis were analyzed. RESULTS: Of total 261 cases, gram-postive bacteria accounted for 56.7%, which were mainly staphylococcus bacteria (41.9%) and gram-negative bacteria (43.3%) among which Escherichia coli accounted for 42.5%. CONCLUSION: Culture and drug sensitivity analysis of prostatic fluid and rational use of antibiotics based on results of drug sensitivity test has significance for drug use in the clinic.

AIM:ToinvestigatetheprotectiveeffectofquercetinonangiotensinⅡ(AngⅡ)-inducedcardio-myocyte hypertrophy and its possible mechanism .METHODS: Cardiomyocyte hypertrophy was induced by AngⅡ ( 100 nmol/L) in primary neonatal cardiomyocytes and H 9c2 cells.The cells were treated with different concentration of querce-tin (10 μmol/L, 20 μmol/L and 40 μmol/L) for 48 h and then the cardiomyocyte surface areas were measured by immu-nofluorescence .Proteasome activity was detected by fluorescent peptide substrate .The phosphorylated levels of GSK-3α/βand Akt in H9c2 cells were determined by Western blot .RESULTS:Compared with control group , the cardiomyocyte sur-face areas were both increased in primary cultured neonatal cardiomyocytes and H 9c2 cells, while the surface areas were significantly decreased by quercetin , especially at concentration of 20 μmol/L compared with Ang Ⅱgroup (P<0.05). Compared with control group , the chymotrypsin-like, trypsin-like and caspase-like activities of proteasome were all in-creased in H9c2 cells (P<0.05).The trypsin-like and caspase-like activities of proteasome were inhibited by 20 μmol/L and 40 μmol/L quercetin , while chymotrypsin-like activity was inhibited only at 20 μmol/L of quercetin compared with AngⅡgroup (P<0.05).In addition, phosphorylated levels of GSK-3α-Ser21, GSK-3β-Ser9 and Akt-Ser473 in AngⅡgroup were all increased compared with control group , which were obviously inhibited by in 20 μmol/L and 40 μmol/L quercetin ( P<0.05 ) .CONCLUSION: Quercetin decreases cardiomyocyte hypertrophy through proteasome inhibition , which may be related to the inhibition of Akt and therefore increasing activation of GSK -3α/βin H9c2 cells.

Intravenous glucose tolerance test(IVGTT)and oral glucose-insulin releasing test(OGIRT) in 12 subjects with normal glucose tolerance were performed.The results showed that the peak of insulin secretion Was at 40 minutes during()GIRT.The ratio of the change of insulin-to-glucose at 40 minutes(△I40/△G40)is an index in reflecting insulin sensitivity and β-cell function.

Objective To explore the influence of screening programme on awareness of cervical cancer prevention among 30 to 59 years old women who live in rural areas of Beijing.Methods A face-to-face cross-sectional survey on women's knowledge on cervical cancer prevention was conducted in 2008 and 2009 among subjects recurited by three-stage stratified random sampling.ResultsUnivariate analysis showed that since the initiation of cervical cancer screening in Daxing District of Beijing,the overall awareness of cervical cancer was significantly increased among women residents,and the percentage of women with 5 or more correct answers was increased from 37.3％ to 51.0％ ( x2=62.06,P＜0.001).After adjusting confounding factors,multivariate analysis showedthat cervical cancer screening programme contributed to improved awareness of cervical cancer-related knowledge ( OR =1.853,95％ CI1.590 -2.159).In addition,current place of residence,education level,household income per-capita and screening history within 5 years were major factors affecting women's awareness of cervical cancer ( OR vales were 1.766,2.580,1.350 and1.676,respectively),and higher education level and personal income were correlated with increased awareness rate.ConclusionCervical cancer screening could improve general knowledge of cervical cancer,especially for those who have never participated in the screening programme.

Objective To observe the effect of Huoluojiangu Capsule(HJC) on anti-inflammatory experiment.Methods The anti-inflammatory experimental models were established in three kinds of rats with pleuritis,the swellen sole of the foot and the PGE_2 content in inflammatory tissues,respectively.Results The swollen reaction in the sole of foot in rats induced by egg white was lessoned with the treatment of low,middle and high dosage of HJC.Compared with the blank control group,the treatment is effective in low dosage group and evidently effective in groups of middle and high dosage after 30 min(P0.05),respectively.Compared with the blank control group,the effect of HJC on the PGE_2 content in the inflammatory tissues of middle and high dosage groups was significant(P

Objective To investigate high risk human papillomavirus(HR-HPV)prevalence among married women in Beijing and to study the high risk flactors.nethods During March 2007 to September 2008.a total of 6185 married women sampled from 137 communities in 12 districts were screened bv HR-HPV DNA test and cytogical test.The interview was carried out with unified questionnaires.The databage was set up and twice entered in EpiDam 3.0.After checked up,the data were analyzed in SPSS 15.0.Results (1) The HR-HPV infection rate was 9.89%.The HR-HPV infection rate of the city zone,the suburb and the exurb were 9.34%,10.51% and 9.51% (P>0.05).The HR-HPV infection rate of the native and the oudander were 9.53%,11.30% (P<0.05).(2) The age distribution of HR-HPV infection was that the rate was around 10% among 25 to 44 age groups,which was the highest(11.21%) in 30 to 34 age group;then the rate was descended as the age raising,the rate of 50 to 54 age group was the lowest(7.78%).(3) Multiple logistic regression showed that the related risk factors of HR-HPV infection mainly included 1000 RMB and above of family income per person per month.possessing more than 1 sexual partner of her husband,outlander and hish levels of education.(4) The prevalence of cervical intraepithelial neoplasia(CIN)in HR-HPV positive group wag significantly higher than that in HR-HPV negative group(29.76% vs 3.32%,P<0.01).Conclusions(1)The HR-HPV infection rate among aged 25 to 54 years was 9.9% and there was no significant difference in area distribution.(2)The hish risk population which should strengthen screening was the married bearing-age women with high level of family income,outlander,high levels of education and her husband possessing more than 1 sexual partner.(3)HR-HPV infection is the main risk factor for CIN and cervical cancer.while does not provide a causal relationship with them.The high risk population should be checked regularly to understand the development of HR-HPV infection and CIN incidence.
