Objective To study the risk factors for pulmonary fungal infection associated with chronic obstructive pulmonary disease (COPD),and evaluate the efficacy and safety of itraconazole for treatment of pulmonary fungal infection associated COPD.Methods A retrospective analysis were conducted on clinical data of 42 COPD patients who were confirmed pulmonary fungal infection in a respiratory disease department from September 1 ,2007 to May 31 ,2012,and 53 COPD patients who had no pulmonary fungal infection were as control.Results Of 42 patients with COPD and pulmonary fungal infection,8 were confirmed by histopathological examination,34 were confirmed by clinical diagnosis;6 were acute cases,36 were chronic cases;28 were positive for fungal detection,6 of whom were detected Candida albicans ,13 were detected Aspergillus ,7 were detected unclassified fungi,and 2 had mixed fungal infection.Univariate analysis showed that underlying diseases,long-term use of broad-spectrum antimicrobi-als,long-term use of glucocorticoid,hypoproteinemia,invasive procedure,invasive mechanical ventilation,diabetes mellitus,history of invasive fungal infection were major risk factors for pulmonary fungal infection associated with COPD.After patients were treated by itraconazole,the improvement rate of clinical symptoms was 66.67%,fungal eradication rate was 60.71 %,total effective rate was 64.29%.Of 28 cases with positive fungal detection,the im-provement rate of clinical symptoms,fungal eradication rate,and total effective rate was 71 .43%(n=20),60.71 %(n=17),and 67.86%(n=19)respectively.Itraconazole had good therapeutic efficacy on acute and chronic pulmo-nary fungal infection associated with COPD.Adverse drug reaction rate was 23.81 %,most were mild and reversi-ble,and had no obvious impact on the treatment.Conclusion Itraconazole has positive clinical efficacy on treating pulmonary fungal infection associated with COPD,it is highly safe.

Objective To compare the license issuance and status of administration of laboratory animals in Jiangsu and Zhejiang provinces in the last five years, and to study the status of laboratory animal license management and industry development level in the two provinces.Methods Taking a combination of current status investigation, literature search, information collection and comparative analysis, to study the similarities and differences in the annual issuance of laboratory animal licenses, level of environmental facility, type of institution division, regional distribution of institutions, etc.in the two provinces over the last five years.Results Over the past five years, the total number of the issued laboratory animal licenses and approved institutions in Jiangsu province are significantly more than in Zhejiang province.The proportion of barrier environmental facilities in Jiangsu is slightly higher than that in Zhejiang.Laboratory animal institutions cover most areas of the provinces, relatively concentrated in the capital cities and economically developed cities.The business type institutions account for the highest percentage in the two provinces.Animal species in the two provinces are approximately the same.Conclusions The industrial structure of the laboratory animals in Jiangsu province is more perfect than that in Zhejiang province.Industrialization and socialization get a higher degree in Jiangsu province.The range of regular species of the laboratory animals needs to be further expanded.The competent departments need further optimize and promote license management system of the laboratory animals.

Objective To investigate the clinical efficacy of acupuncture at Hegu plus Fuliu in treating hyperhidrosis in Parkinson’s disease. Methods Fifty-seven Parkinson’s disease patients with hyperhidrosis were randomly allocated to a treatment group of 28 cases and a control group of 29 cases. The control group received conventional acupuncture and the treatment group, acupuncture at Hegu plus Fuliu in addition. The VAS score and the HDSS score were recorded in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results There were statistically significant pre-/post-treatment differences in the VAS score and the HDSS score in the two groups (P<0.01). There were statistically significant post-treatment differences in the VAS score and the HDSS score between the treatment and control groups (P<0.01). The total efficacy rate was 96.4% in the treatment group and 72.4% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Acupuncture at Hegu plus Fuliu can effectively reduce hyperhidrosis in Parkinson's disease patients.

By now,the mutations of C-KIT gene and PDGFRA have been regarded as the most important primary incidences.The latest results have revealed the fact that the abnormal expressions of p53,p16,p21 WAF-1,p27 and E-cadherin(cDH1) which were labeled as anti-oncogenes in most of human tumors,existed in the progression of gastrointestinal stromal tumor.Therefore,we put forward the theory that gene mutaion may lead to the instability of DNA that further promotes mutation of short tandem repeat in anti-oncogene coding region,on basis of which,that finally lead to the malignant progession of gastrointestinal stromal tumor by anti-oncogene mutation.

Objective:To detect and compare the intensity of gingipain K(Kgp)in culture medium and cell extract of Porphyromonas gingivalis(P.gingivalis)isolates in puberty gingivitis,and then to reveal the possible relationship between Kgp and puberty gingivitis.Methods:36 patients with puberty gingivitis aged from 14 to 17 years were enrolled.Clinical parameters including GI,SBI and PD were evaluated before subgingival plaque samples collection.Subgingival plaque samples were collected and then P.gingivalis isolates were obtained.16S rRNA PCR was used to confirm the presence of P.gingivalis in clinical isolates.Bacteria were cultured in BHI agar base and harvested at the end of log-phase growth.Culture fractions of P.gingivalis(culture medium and cell extracts)were performed with SDS-PAGE and Western blot technique using primary antibody against specific anti-Kgp N-terminal IgG subdomain.The data were statistically analyzed using SPSS 11.5 software.The relationship between the Kgp intensity and the clinical parameters was statistically analyzed using sum rank test.Results:There was positive correlation between the intensity of Kgp N-terminal IgG subdomain and the clinical parameters(P

Objective: To study the effects of Total Saponins of Panax Pseudoginseng injection on unstable angina pectoris (UAP) .
