Objective To reveal and forecast the incidence trend of Brucellosis, in order to provide acientific basis for future intervention and policy-making. Methods Descriptive epidemiological method was used to analyze and statistically describe the distribution of the disease in different times, different locations and different (7.0783/10 million to 13.1257/10 million) and Qingxu ( 1.4811/10 million to 8.5241/10 million) were higher,followed by Yangqu county(0 to 5.8232/10 million), Xiaodian(0.8108/l0 million to 2.4229/10 million) and Jinyuan district ( 0.5329/ 10 million to 1.5896/10 million), and the remaining counties(districts) in the annual There were 223 cases of Brucellosis patients from 2006 to 2009 in Taiyuan. Vocational high risk population was farmers, with a total of 140 cases, accounting for 62.78% of the total number of incidence, followed by students and workers, respectively, 13, 14 cases, accounting for 5.83% and 6.28%, other occupational groups, 56 cases,77.58%;28 cases aged above 60 years, accounting for 12.56%;22 cases aged younger than 19 years, accounting identical in the four years, most cases occurred in spring and summer and showing a clear seasonal high.Conclusions The incidence trend of Brucellosis is on the rise from 2006 to 2009. High risk population is farmer,and the number of younger patients is on the rise, we propose strengthen protection for high risk groups.

OBJECTIVETo observe the correlation between constitution of yin deficiency syndrome (YDS) and polymorphism of HLA-DQA1/treatment response of Peg-lFNalpha therapy in HBeAg positive chronic hepatitis B (CHB) patients, and to explore constitution of Chinese medicine (CM) in response of interferon therapy.

METHODSTotally 120 HBeAg positive CHB patients who were treated with Peg-IFNalpha were enrolled, and assigned to YDS group (59 cases) and non-YDS group (61 cases) according to classification of CM constitutions. All patients were subcutaneously injected with Peg-IFNalpha-2b (1.0 microg/kg body weight) or Peg-IFNalpha-2a (180 microg), once per week. Effective efficacy was primarily judged when complete response (CR) or partial response (PR) was obtained at month 6. Those with CR or PR completed 1 year therapeutic course. HLA-DQA1 gene types were detected by polymerase chain reaction sequence specific primers (PCR-SSP). The distribution difference of CM constitutions in patients with CR or PR and their inter-group HLA-DQA1 allele frequency were compared.

RESULTSDifferent treatment responses of Peg-IFNalpha were observed in CHB patients of two different CM constitutions. The ratio of CR + PR was 61.0% (36/59) in YDS group, obviously lower than that in NYDS group [78.7% (48/61), P < 0. 05]. Patients with CR had a lower allele frequency of HLA-DQA1 * 0501 than those with no-response [14.8% (8/54) vs. 30.6% (22/72)] with statistical difference (P < 0.05). Patients with CR had a higher allele frequency of HLA-DQA1 * 0601 than those with no-response [18.5% (10/54) vs. 5.6% (4/72)] with statistical difference (P < 0.05). The allele frequency of HLA-DQA1 * 0301 was lower in YDS group than in non-YDS group [2. 5% (3/118) vs. 9.8% (12/122)] with statistical difference (P < 0.05). The allele frequency of HLA-DQA1 * 0501 was higher in YDS group than in non-YDS group [33.9% (40/118) vs. 18.9% (23/122)] with statistical difference (P < 0.05). Yet statistical significance was lost after adjustment (Pc > 0.05 for both).

CONCLUSIONSBoth constitutions of CM and HLA-DQA1 gene polymorphism af- fect HBeAg positive CHB patients' response to Peg-INFalpha. Constitutions of YDS and HLA-DQA1 * 0501 was not favorable to response, their association needed to be further studied.

Objective To provide the guidance for the control and treatment of blood stream infec-tion caused by Serratia marcescens strains through analyzing the homology and drug resistant genes of the iso-lates collected from the Intensive Care Unit ( ICU) of Shaoxing County Central Hospital.Methods Serratia marcescens strains were isolated from ICU patients with blood stream infection and also from the hands of health care providers in the ICU from June 1st to September 30th, 2013.The antibiotic susceptibilities of the Serratia marcescens isolates were tested.PCR was performed to amplify the common drug resistant genes. Pulse-field gel electrophoresis ( PFGE) was carried out for analyzing the homology of all isolates.The com-plete clinical data of the patients were collected and statistically analyzed with Spearman′s rank correlation coefficient.Results Seventeen strains were isolated in this study.All of the 17 strains were resistant to the first and second generation Cephalosporin, Gentamicin and Ciprofloxacin, and sensitive to Amikacin and Ceftazidime.The drug resistant rates to Carbapenems ranged from 11.76%to 35.29%.One of the isolates (5.88%) carried the TEM gene.The results of PFGE showed that the phenotypes of all isolates were identi-cal.Conclusion Serratia marcescens strains were critical hospital infectious pathogens.They were able to spread in the hospital and were resistant to multiple antibiotics.Clinical physicians should properly use anti-biotics for the patients based on the result of drug susceptibility test.A control regulation for Serratia marces-cens infection within hospital should be enforced to avoid the cross infection and the outbreak of resistant strains.

Objective: To observe the effect of acupuncture on Akt2 mRNA expression in skeletal muscle of insulin resistant rat models. Methods: Twenty-four SD rats were randomly divided into a control group, a model group and an acupuncture group. Fasting plasma glucose (FPG), fasting insulin (FINS), insulin sensitivity index (ISI), C peptide (C-P), as well as Akt2 mRNA expression in skeletal muscle of rats were detected by glucose oxidase method, ELISA and real-time PCR. Results: Compared with the control group, the level of FPG, FINS and C-P increased significantly (P<0.01) while ISI and Akt2 mRNA expression decreased markedly in the model group (P<0.01, P<0.05). In the acupuncture group, the levels of FPG, FINS and C-P were much lower than in the model group (P<0.01, P<0.01,P<0.05) and ISI and Akt2 mRNA expression increased markedly (P<0.01). Conclusion: The mechanism of acupuncture in treating insulin resistance may relate to the up-regulated of the Akt2 mRNA expression and to the improvement of the signal transduction of PI3K pathway.

In this study, 120 patients with rheumatic heart disease undergoing valve replacement were randomly divided into the control group and the Qishen group, with 60 cases in each group. Before the operation, the control group was given routine heart and diuretic treatments and placebo of Qishen Yiqi dropping pills for seven days (0.5 g each time, three times a day); While the Qishen group was given Qishen Yiqi dropping pills for seven days (0.5 g each time after meal, three times a day) on the basis of the routine treatments. The right ventricular end-diastolic volume (RVEDV), end-systolic volume (RVESV), stroke volume (SV) and right ventricular ejection fraction (RVEF) were detected after the operation. The results showed that patients in the two groups showed significantly lower right ventricular end diastolic volume (RVEDV), right ventricular end systolic volume (RVESV) and stroke volume (SV) decreased than that before the operation, but with significantly higher Ejection fraction (RVEF) significantly than that before the operation. However, the Qishen group showed a significantly lower right heart function reduction than the control group, with the statistical significance in the differences (P < 0.05). This indicated that the pretreatment with Qishenyiqi Drop Pills showed a remarkable efficacy in the improvement of right ventricular function after valve replacement.

Objective To study the function of core protein (CORE) of genotype 1b hepatitis C virus (HCV) of different strains (T: derived from tumor tissues; NT: derived from non-tumor tissues; C191: HCV-J6) and different domains (1-172, 1-126, 1-58, 59-126, 127-172 AA) of T CORE in the pathogenesis of HCV infection and to find the therapy target. Methods Different truncated genotype 1b HCV CORE eukaryotic expression plasmids (T, NT, C191) and different domains of T CORE were constructed and transfected to HepG2 cells. Cell apoptosis and necrosis were quantified by flow cytometry. Cell growth curves were observed with real time cell growth instrument. Results COREs from different strains of genotype 1b and different domains of CORE induced cell apoptosis and necrosis, and inhibited HepG2 cell growth at different levels. CORE derived from T induced apoptosis and necrosis and inhibited cell growth higher than that derived NT and C191. N terminal 1-58 AA of CORE derived from T induced cell apoptosis and necrosis and inhibited cell growth higher than any other domains. Conclusion COREs from different strains of genotype 1b HCV and different domains of CORE from the same HCV strain play different roles in their molecular pathogenesis of HCV. Among different domains of CORE, N terminal 1-58 AA might play an important role in its pathogenesis and be one target of gene therapy.

The contamination of extrinsic harmful contaminants including mycotoxins, heavy metals and pesticides, etc, brings serious risks to traditional Chinese medicines (TCMs), further to human health. Due to their unique photoluminescence, chemiluminescence, electrochemical and electrochemiluminescence properties, semiconductor quantum dots (QDs) nanoparticles are widely used to immobilize bioprobes and biosensors, etc. In this review, the luminescence characteristics and specific ligands of QDs probles which are used to determine contaminants were summed up. Then, the applications of QDs-coated novel probes in the determination of mycotoxins, heavy metals and pesticides were discussed in detail. In addition, the contamination levels and characteristics of extrinsic harmful residues in TCMs were investigated. Further, the maximum levels of those contaminants in TCMs were compared with those set by various countries. Finally, the future development trends and problems of QDs-coated probes in the determination of those extrinsic residues in TCMs were prospected.
