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 study the level and structure of intelligence in children with benign epilepsy of childhood with centrotemporal spikes(BECT)and investigate factors affecting their intelligence.Methods Congitive skills such as intelligence quotient(IQ),phonological test and morphological test,were evaluated in 47 children with BECT,and the results were compared to a control group of 30 children matched for gender,age,level of education and family background.The effects of age of onset,disease course,seizure frequency,seizure type,location of spike,and spike and wave index(SWI)on the level and structure of intelligence were also analyzed.Results The total IQ score was slightly lower in children with BECT(104.20±12.34)when compared to the control group of normal children(109.45±15.01),but the difference was not significant.There was no difference in performance IQ scores between BECT and normal children.BECT children had a lower verbal IQ score(90.67±18.40)when compared to the control group(98.17±13.18,t=3.431.P<0.05).Analyses of verbal subtests revealed significant differences between BECT and normal children in vocabulary and similarities(5.97±2.95 vs 8.51±3.67 and 4.85±3.02 vs 6.95±3.07,respectively,t value were 2.365 and 2.096,both P<0.05).The differences between BECT and normal children were also significant in phonological test and morphological test (12.56±2.3 vs 16.78±3.72 and 22.35±3.25 vs 24.15±5.28,respectively,t=2.478 and 2.770,both P<0.05).SWI was negatively correlated with verbal IQ,vocabulary,similarities,phonological test and morphological test(r=-0.305--0.838,P<0.05).Age of onset,disease course and seizure frequency were not correlated with verbal IQ,phonological test and morphological test.The level of intelligence was not different among children with left hemispheric foci,fight hemispheric foci or bilateral foci.The level of intelligence Was similar between children with partial seizures or secondarily generalized seizures.Conclusions Children with BECT have normal level of intelligence,but the structure of intelligence is abnormal with retardation of their language ability.SWI affects the language ability in children with BECT,but age of onset,seizure type and location of spike do not influence their language ability.

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.

ObjectiveTo determine the optimal timing of antenatal taurine supplementation to improve neuron and neural stem cell proliferation in fetal rats with intrauterine growth restriction.Methods Twenty-five pregnant SD rats were randomly divided into five groups (five rats in each group): group A was the control group, group B to E were the fetal growth restriction (FGR) model groups with low-protein diet during the experiment, group C, D, and E were supplemented with taurine [300 mg/(kg·d)] at day 9, 11 and 15, respectively. The birth weight of newborn rats was measured after natural delivery. The rats with body weight two standard deviations lower than the average weight in group A were diagnosed as FGR. There were five litters of newborn rats in each group, and two were randomly selected from each litter, resulting in ten newborn rats in each group. Proliferating cell nuclear antigen (PCNA) and fatty acid binding protein 7 (FABP7) positive cell expression in newborn rat brain tissues were detected by immunohistochemistry. Single factor analysis of variance, LSD tests were used for statistical analysis.ResultsThe average birth weight of newborn rats in group A, B, C, D and E were (6.61±0.45), (4.65±0.23), (5.37±0.17), (5.74±0.21), and (5.00±0.24) g, respectively. Average birth weight was lower in group B than in group A (t=2.447), higher in group D and E than in group B (t=2.306 and 2.306), higher in group D than in group C and E (t=2.306 and 2.306), and the differences were statistically significant (allP<0.05). The positive expression of PCNA in the brain of neonatal rats was mainly located in the nucleus. The number of PCNA positive cells in each high power field (×400) in group A, B, C, D and E was 31.03±5.38, 46.49±4.38, 59.65±5.37, 67.76±5.84, and 53.53±6.94, respectively. The number of PCNA positive cells in group B was higher than that in group A (t=2.110), higher in groups C, D and E than in group B (t=2.110, 2.110 and 2.131), higher in group D than in group C and E (t=2.101 and 2.110), and the differences were all statistically significant (allP<0.05). The positive expression of FABP7 was mainly located in the cytoplasm of neonatal rat brain. The integral optical density (IOD) in group A, B, C, D, and E was 451 733.1± 141 452.3, 207 232.2±60 525.2, 333 766.6±68 412.1, 380 647.4±131 145.9, and 278 967.1±127 630.7, respectively. The IOD in group B was lower than that in group A (t=3.165,P=0.000), higher in groups C, D and E than in group B (t=5.272, 7.132, 2.950), and the differences were statistically significant (allP<0.05). Although the IOD in group D was higher than that in group C, the difference was not significant (t=1.953, P>0.05). The IOD in group D was higher than that in group E, and the difference was statistically significant (t=4.182,P<0.05).ConclusionsAntenatal taurine supplementation can promote neuron and neural stem cell proliferation in rats with FGR. The effect is most obvious on the 11th day of pregnancy, and may lead to the promotion of brain development.
