Objective To evaluate the role of procalcitonin (PCT) in the diagnosis and treatment of infective endocarditis (IE).Methods It was a retrospective study of 20 cases diagnosed as IE with positive culture between June 2010 and June 2012 of First Affiliated Hospital of China Medical University,Department of Infectious Diseases.Results The concentration of C-Reactive Protein (CRP) and PCT in the dead group recorded on the first day and the fifth day in the treatment was significant higher than the survival group.The decreased degree of CRP and PCT concentration after treatment in the dead group was much deeper than the survival group.Moreover,the concentration of CRP and PCT in Staphylococcus aureus IE and negative bacilli IE were significant higher than Streptococcus viridans IE or Enterococcus faecalis IE,which was commonly above 2 μg/ml level.Conclusions Serum procalcitonin,lined with CRP,has the similar significance in the assessment of infective endocarditis severity,however,PCT is slightly better than CRP in assessing prognosis.The concentration of procalcitonin has implications to the strains of IE pathogen,in the mean time,it' s beneficial to guide the early use of antibiotics.

The innovation in each aspect of medical and public health territory in our state gradually becomes the social focus.We analyze the key issues in the new type medical innovation in this paper,including clarifying government-dominant leadership of the medical innovation,identifying public welfare property of station-owned hospitals as the direction of medical innovation,impelling public health agency to perform total amount of money budget,and setting everyone's enjoying elementary medical service as the ultimate target of the medical innovation.Meanwhile,some beneficial opinions are also introduced in the paper.

In view of the present hospital professional and technical personnel in the making , performance e-valuation , salary management , personal development , health management , department management , as well as on the management of some of the ethical issues , analyzes its reason: hospital professional and technical personnel management ethics idea misunderstanding , hospital professional and technical personnel subject ethics value status unclear , hospital professional and technical personnel managers′ethical level is not high .And put forward the con-crete solving measures:strengthen dominated by social responsibilities of ethical supervision and management , es-tablish the principle of fairness , justice , ethics of competition system , director of the department , carried out by both efficiency and fair ethics idea of performance and salary rank management activities , to achieve individual all-round development as the goal of ethical career management , to strengthen the management of managers ethical education .

Objective To compare the contents of guanosine and adenine in peels of three strains of Trichosanthes kirilowii Maxim.;To provide references for germplasm resources evaluation and breeding of the Chinese medicinal materials. Methods HPLC method was used to determine the contents of guanosine and adenine with Waters AtlantisT3-C18 column (4.6 mm×150.0 mm, 5 μm). The mobile phase was methanol and water, and the detection wavelength was 254 nm. Results The contents of guanosinein in peels of three strains of Trichosanthes kirilowii Maxim. were 0.159 4, 0.159 6, 0.134 1 mg/g, respectively;the contents of adenine were 0.097 1, 0.127 9, 0.093 4 mg/g, respectively. Conclusion There were significient differences in the contents of adenine among three strains of Trichosanthes kirilowii Maxim.. Strain Ⅱ is with higher level of guanosine and adenine, which implies that the breeding of the Chinese medicinal materals is one way to improve the quality of Trichosanthis Exocarpium.

AIM: To observe the pathologic changes in lung and the role of p38 MAPKinase signal pathways in pulmonary alteration in diabetic rats. METHODS: Diabetic rats were induced by intraperitoneally injected streptozotozin (STZ). After 4 weeks,we observed the pathologic changes in lungs,tested protein kinase C (PKC) activities by isotope in lungs of model rats,tested transforming growth factor (TGF-?_1) by Western blotting and immunohistochemical analysis,and determined the expression of p38 MAPKinase mRNA using in situ hybridization.RESULTS: After STZ administration for 4 weeks,we observed thickened pulmonary capillary basal lamina and increased number of fibre in Diabetes mellitus (DM) rats. TGF-?_1 levels,PKC and p38 MAPK activities were also found increased. CONCLUSION: The increased activities of TGF-?_1 and p38 MAPK suggeste that TGF-?_1 may play an important role in diabetic lung,and hyperglycemia-PKC-p38 MAPK signal pathways may be involved in the pathogenesis of diabetes.
