Objective To investigate the effects of different dosage of atorvastation on inflammatory factors in patients with unstable angina(UAP)post PCI.Methods 116 patients with their coming order were randomly divided into two groups.The observation group of 56 cases with the dosage of 20mg/d,and the control group of 60 cases with the common dosage of 10mg/d.Blood samples were examined at the day of the operation preoperatively,24 h after PCI,4W,12W after administration.Results(1)The consistency of hs-CRP and cTnI of patients after PCI were more higher than that before PCI(P

Objective To observe the principles of cell proliferation and apoptosis in the developing mouse cochlear sensory epithelium, and investigate correlation with differentiation of hair cells.Methods The developing inner ears of C57BL/6 embryonic mice,aged from eighth embryonic day (E8) to just natal mice (P0), were observed by transmission electron microscope.Results Cochlear primordium arose at E10. After E14, sensory epithelia began to differentiate. Corti primordium arose at E16, and shapes of supporting and hair cells tend to mature. But the organ of Corti was still poorly developed at P0. Meanwhile Cell karyokinesis of the cochlea arose at E11 ,then gradually increased. But it began to decrease from E14. Cell apoptosis arose at E13.It reached its peak from E14 to E15,then it began to decrease gradually.Conclusion Cell proliferation and apoptosis were inevitable in the developing mouse cochlea.Cell proliferation, cell apoptosis and differentiation of hair cells consequently arose and overlapped each other. Homeostasis between cell proliferation and apoptosis has an important role in the developing mouse cochlear sensory epithelium.

Objective To study the intra- tumor basis of pleural indentation (P I) and find the influential factors correlated with PI in peripheral lung cancer . Methods Eighty-six cases of peripheral lung cancer (includin g experimental gr oup of 34 cases with PI and control group of 52 cases without PI) were subjected to identify the constitution in tumoral interstitium. And 7 variables (includin g intra-tumor fibrosis, tumor-chest wall distance, histological type, diameter o f tumor, differentiated degree, lymphatic metastases, sex, etc.) were investigat ed about PI by single factor analysis and multiple factor analysis of Logistic r egression model. Results(1)Collagenous fibers were the mai n fiber in tumoral interstitium, and were higher in experimental group than that in control group ( t=3074, P005). Conclusion Collagen Ⅰfibers are the main type of interstiti al fibers, and myofibroblasts are the main type of interstitial cells in PI asso ciated peripheral lung cancer. Intra-tumor fibrosis, tumor-chest wall distance , and histological types are the main influential factors in PI formation, and int ra-tumor fibrosis is the basic and inside factor. The histological types affect PI formation. Tumor-chest wall distance plays an important outside role in PI f ormation.

Objective To investigate the effect of kangaroo mother care on children′s comfort with intramuscular injection. Methods One hundred children with an intramuscular injection were grouped according to the injection date. Those treated with injection on odd-numbers days were assigned as the intervention group , and those with injection on even-numbered days as the control group, with 50 cases in each group. The control group received routine care and the intervention group with kangaroo mother care. The two groups were compared in terms of comfort level. Result The comfort level of the observation group was higher than that of the control group with statistical significance (P<0.01). Conclusion Kangaroo mother care can improve the comfort level of children patients with intramuscular injection. It is a simple, safe and effective in non-pharmaceutical pain therapy.

The inter-species differences of estradiol metabolism were investigated in human, Beagle dog and rat liver microsomes by comparing enzyme kinetics of parent drug and the formation of its major metabolites. The incubation systems of estradiol with liver microsomes of the three species were optimized in terms of estradiol concentration, microsomal protein content and incubation time. The concentrations of estradiol and its metabolites were measured by LC-MS/MS method. The t1/2, CLint, CLh, Km and Vmax of estradiol incubated with male human liver microsomes were 40.02 +/- 8.32 min, 41.39 +/- 6.57 mL x min(-1) x kg(-1), 13.81 +/- 12.36 mL x min(-1) x kg(-1), 26.8 +/- 6.99 micromol x L(-1) and 0.75 +/- 0.92 micromol x L(-1) x min(-1), respectively. The corresponding parameters of female human were 44.71 +/- 10.21 min, 29.85 +/- 8.97 mL x min(-1) x kg(-1), 0.01 +/- 0.68 mL x min(-1) x kg(-1), 44.2 +/- 7.73 micromol x L(-1) and 1.27 +/- 4.41 micromol x L(-1) x min(-1), that of male dog were 21 +/- 7.33 min, 165.53 +/- 29.33 mL x min(-1) xkg(-1), 26.01 +/- 8.39 mL x min(-1) x kg(-1), 19.5 +/- 7.34 micromol x L(-1) and 1.6 +/- 0.65 micromol x L(-1) x min(-1), that of female dog were 25.5 +/- 5.32 min, 135.11 +/- 42.34 mL x min(-1) x kg(-1), 0.24 +/- 3.18 mL x min(-1) x kg(-1), 8.33 +/- 6.32 micromol x L(-1) and 0.51 +/- 2.15 micromol x L(-1) x min(-1), that of male rat were 5.11 +/- 3.84 min, 485.63 +/- 36.52 mL x min(-1) x kg(-1), 49.57 +/- 15.29 mL x min(-1) x kg(-1), 62 +/- 13.74 micromol x L(-1) and 19.16 +/- 9.67 micromol x L(-1) x min(-1), and that of female rat were 7.0 +/- 3.69 min, 354.82 +/- 33.33 mL x min(-1) x kg(-1), 8.04 +/- 3.23 mL x min(-1) x kg(-1), 35.38 +/- 7.65 micromol x L(-1) and 8.39 +/- 4.91 micromol x L(-1) min(-1), respectively. There were nine metabolites detected from all the three species, but the relative amounts of the metabolites generated were different in three species. The results indicted that the major phase I metabolic pathway of estradiol was similar in the liver microsomes from all the three species. However, the inter-species differences were found in the view of relative amounts of the metabolites as well as the metabolic characteristics of estradiol in liver microsomal incubation.
