ObjectiveTo investigate the intervention of level of atorvastatin calcium tablets (lipitor) on soluble CD40 (CD40L) and high sensitivity C-reactive protein (hs-CRP) in patients with angina.Methods 65 patients with coronary heart disease were divided into stable angina (SA group,n= 30) and unstable angina (UA group,n= 35).The vein blood was collected in the hospitalized morning,2,4,6 weeks after treatment and serum levels of hs-CRP and CD40L were measured and compared between the two groups.ResultsThe levels of soluable CD40L [(20.52± 2.91)μg/L] and CRP [(7.96±1.69) mg/L] in UA group were higher than SA group [(7.96±-1.35) tg/L and ( 1.58 ± 0.91 ) mg/L] (t = 21.705、18.493,both P＜ 0.05) before treatment,and after treatment,their levels in the two groups were significantly lower than pre-treatment (P＜0.01).ConclusionsCD40L and hs-CRP may involved in the pathophysiology of unstable angina process and can be used as an indicator reflecting vulnerable plaque.Lipitor might enhance stability of atherosclerotic plaque and prevent acute coronary events by reducing levels of CD40L and hs-CRP.

OBJECTIVE:To determine whether bacterial endotoxins test(BET) can replace the pyrogen test for the sodium bicarbonate injection.METHODS:The comparative experiment of tachypleus amebocyte lysate(TAL) and rabbits were studied to determine the sensitivity.RESULTS:The sensitivity of TAL test was 0.125 EU.ml－1, 12 times higher than that of using rabbits.CONCLUSIONS:BET may replace pyrogen test.

Objective To investigate the effects of stretch load on the quantity of rat bladder interstitial cells of Cajal (ICCs) and c-kit expression in the cells. Methods Rat models of detrusor instability with partial outflow obstruction were established. The quantity of ICCs and c-kit expression in ICCs from stable, unstable and normal detrusor were studied with light microscopy and Western blotting. Results The quantity of ICCs and expression of c-kit in the stable and unstable detrusors were higher than that in normal control group (P

Objective To investigate the effects of stretch load on the ultramicrostructure and c-kit expression of the bladder interstitial cells of cajal (ICCs) in rats. Methods Rat model with detrusor overactivity due to partial outflow obstruction with bladder neck ligation were established. The effects of stretch load on the changes of ultramicrostructure of the bladder ICCs were observed by scanning electron microscopy. The changes in c-kit gene expression of ICCs in stable, overactive, and normal detrusors were analyzed with RT-PCR. Results The ultramicrostructure of the ICCs changed significantly. The expression of c-kit was significantly higher in the overactive group than that in stable and normal groups (P

Objective To identify PRKAR1A mutations in a pedigree with Carney's complex through clinical investigation and molecular biology research,and to summarize the genetic law,characteristics,and clinical features of this family disease.Methods The family members received a detailed medical examination and related biochemical tests.The hereditary history and clinical features were recorded.DNAs of 12 family members were extracted from blood and 9 exons and adjacent introns of PRKAR1A were sequenced.Results PRKAR1A mutation intron4 c.440+4 delG was identified in 7 family members,including the proband's patient,who presented special signs of pigmentation on the lips,buccal mucosa,and fingertips.Conclusions The deletion mutation (c.440+4del G) in intron 4 of the PRKAR1A gene was found in this family,which is possibly associated with the phenotype skin pigmentation.

Objctive To study the effects of traditional Chinese medicine S Kangdu mixture on functions of immune system and bone marrow in mice. Methods Animal model, which marrow and immune system were inhibited, was established by 60 Co or cyclophosphamide injection. The mixture was administrated orally. The white blood cell counts, spleen colony formed unites (CFU S), and the index of carbon clean up were measured. Results The mixture obviously improved leukopenia in peripheral induced by cyclophosphamide administration, and facilitated marrow karyocyte proliferation and formation of CFU S in 60 Co treated mice and reinforced phagocytosis of mononuclear phagocytic system in cyclophosphamide treated mice. Conclusion Traditional Chinese medicine S Kangdu mixture can significantly ameliorate immunological function and stimulate hemopoietic function in mice.

In order to provide us new clues to induce some endogenous protective molecular mechanisms, the changes in gene expression profile induced by ischemia-reperfusion in pulmonary tissues of rats were investigated and the dynamic mechanism of pulmonary ischemia-reperfusion injury was elucidated. Thirty male Wistar rats were randomly divided into 6 groups: 5 ischemia-reperfusion (I/R) groups (I/R 0-h, I/R 1-h, I/R 3-h, I/R 6-h, I/R 24-h) and control group (n=5 in each). An in situ ischemia-reperfusion lung injury rat model was established by occluded hilus of lung. The RatRef-12 Expression Beadchip (22 226 gene probes per array) was used to analyze the pattern of gene expression in all groups. The results showed that 648, 340, 711, 1279 and 641 genes were differentially expressed in I/R 0-, 1-, 3-, 6-and 24-h groups respectively. The differentially expressed genes were classified as following 7 functional categories: cytokine, adhesion molecule, growth factor and apoptosis-related factor, oxidation and antioxidation molecule, metabolic enzyme, ion channel and aquaporin, signal transduction molecule. It was suggested that gene chip technology was an effective and quick method for screening differentially expressed genes. Many differentially expressed genes with different functions interacted each other to result in pulmonary ischemia-reperfusion injury.
