Objective To evaluate the epidemiological characteristics of brucellosis in Jinan city and to identify its cause in order to provide evidence for development of specific preventive strategies in the future.Methods Epidemic information of the disease and survey data of brucellosis cases from 2002 to 2008 in the Infectious and Endemic Disease Control Jinan Centre for Disease Control and Prevention were analyzed statistically.Results From 2002 to 2008, 52 cases were diagnosed as brucellosis, among which 39 cases from Zhangqiu city.The incidence rate ranged from 0.02 to 0.10 hundred thousandth from 2002 to 2006, and 0.25 and 0.26 hundred thousandth in 2007 and 2008, respectively. The disease was found each mouth throughout the year, marked with summer peak[38.46%(20/52)]. Patients increased year after year in summer and spring seasons(r = 0.92, P < 0.01) .The disease was most commonly found in 30 - 59 age group[69.23%(36/52)];men women incidence ratio was 1.67: 1.00;farmers accounting for 94.23%(49/52). There were 5 clusters of family outbreak brucellosis, involving 12 cases. Forty five patients contacted with sheep, accounting for 86.54% (45/52). Conclusions Brucellosis epidemic in Jinan is in an upward trend, mainly in summer and spring, elderly and middle-aged men farmers are the majority of patients. Zhangqiu of Jinan city is a key place for prevention and control of brucellosis;source of infection is not completely eliminated, exotic livestock have not been effectively quarantined, practitioners with weak sense of self-protection is the main reason of the epidemic rise.

OBJECTIVETo evaluate the curative effect of Danxiaoling Pill (DXLP), a Chinese herbal preparation, in treating intrahepatic cholestasis in pregnancy (ICP).
METHODSFifty-eight cases of ICP were divided randomly into two groups and treated by DXLP and Composite Yiganling as control respectively with the other identical conventional treatment. The changes of clinical symptoms, related laboratory parameters after treatment and the condition of labor were observed.
RESULTSThe total effective rate in both groups was 100%, but the markedly effective rate in the DXLP treated group was higher than that in control group (P < 0.01). Levels of blood cholyglycine acid (CGA), alanine transaminase (ALT), aspartate transaminase (AST), total bilirubin, total cholesterol and low density lipoprotein were all decreased in both groups after treatment, but DXL showed a better efficacy in decreasing CGA, ALT and AST than that of Yiganling. Moreover, the amniotic fluid meconium contaminated rate, premature delivery occurrence in the DXLP group were lower than those in the control group, while the weight of newborn baby was higher in the former than in the latter.
CONCLUSIONDXLP could effectively lower the serum bile acid and improve liver function in treating ICP.

This study was designed to analyze the effect of the mitochondrial respiratory pathways of Candida albicans (C.albicans) on the biofilm formation.The 2,3-bis (2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide (XTT) reduction assay was used to measure the metabolic activities of biofilms formed by the C.albicans which were cultured in the presence of respiratory pathways inhibitors.The biofilms formed by the wide type (WT),GOA1-deleted (GOA31),GOA1-reconstituted (GOA32),AOX1a-deleted (AOX1) and AOX1b-deleted (AOX2) C.albicans strains were examined by the XTT reduction assay and fluorescence microscopy.The expression of adhesion-related genes BCR1,ALS1,ALS3,ECE1 and HWP1 in the biofilms formed by the above five C.albicans strains was detected by real time polymerase chain reaction.It was found that the metabolic activity of biofilms formed by C.albicans was decreased in the presence of alternative oxidase inhibitor whereas it was increased in the presence of classical mitochondrial respiratory pathway complex Ⅲ or complex Ⅳ inhibitor.AOX1 strain produced scarce biofilms interspersed with few hyphal filaments.Moreover,no significant changes in the expression of BCR1 and ALS3 were observed in the AOX1 strain,but the expression of ALS1 and ECE1 was down-regulated,and that of HWP1 was up-regulated.These results indicate that both AOX1 and AOX2 can promote the biofilm formation.However,AOX1a primarily plays a regulatory role in biofilm formation in the absence of inducers where the promoting effect is mainly achieved by promoting mycelial formation.

?AlM: To evaluate the clinical efficacy of posterior continuous curvilinear capsulorhexis ( PCCC ) combined with anterior vitrectomy in preventing posterior capsule opacification of congenital cataract surgery.
?METHODS:Postoperative clinical follow-up data of 82 cases ( 87 eyes ) with congenital cataract treated in Eye Center of our hospital from January 2011 to August 2014 were retrospectively analyzed. The patients were divided into the surgical control group ( 38 cases, 40 eyes, recieved phacoemulsification + PCCC ) and the study group ( 44 cases, 47 eyes, accepted phacoemulsification+ PCCC + anterior vitrectomy). The incidence of central optic axis opaque and postoperative visual acuity distribution were recorded at 1a follow - up. lntraoperative and postoperative complications were observed.
?RESULTS:The rate of central optic axis opaque grade 0 in control group was 37. 5%, compared to 76. 6% in study groups. The opacity distribution ratio of grade 1,2,3 and 4 in study group were lower than that of control group, and the central optic axis opacity distribution ratio in study group was significantly better than that of control group (P<0. 05). The 19 eyes(47. 5%) of visual acuity testing ≤0. 5 in control group , was higher than the 7 eyes(14. 89%) of that in the study group, The 21 eyes (52. 5%) of visual acuity testing >0. 5 in control group was lower than the 40 eyes ( 85. 11%) of that in study group. The visual acuity between two groups has statistical significance difference after 1a follow-up ( P<0. 05 ) , and the visual acuity in study group was significantly better than that in the control group. The postoperative intraocular pressure at 1mo and 1a follow-up was lower than before operation in two groups ( P<0. 05), but there was no significant difference between two groups in intraocular pressure (P<0. 05).
?CONCLUSlON: Combination of phacoemulsification, PCCC and anterior vitrectomy presents reliable clinical effects on postoperative central optic axis opacity distribution ratio and visual acuity, and it should be adopted to prevent the occurrence of posterior capsule opacification.
