Evaluation on application of electrolyte module in OLYMPUS AU 5421 Automatic Biochemical Analyzer / 国际检验医学杂志

Objective To evaluate the performance of electrolyte module in OLYMPUS AU5421 Automatic Biochemical Analy-zer in K+ ,Na+ ,Cl- detection .Methods Electrolyte module in OLYMPUS AU5421 Automatic Biochemical Analyzer was employed to detect K+ ,Na+ ,Cl- ,and their precision ,accuracy ,linearity range ,cross-contamination and the test results of instruments were compared .The linear regression equation and regression coefficients were calculated according to the methods of Clinical and Labo-ratory Standards Institute(CLSI) EP6-A ,EP9-A2 documents .Results The within-run precisions of K + ,Na+ ,Cl- were 0 .328% , 0 .306% ,0 .343% ,respectively ,and their between-run precisions were 0 .780% ,1 .012% ,0 .985% ,respectively .Their regression coefficients of linear equation were all greater than 0 .999 ,and their cross-contamination rate were 1 .066% ,0 .812% and 0 .858% , respectively .Conclusion Electrolyte module in OLYMPUS AU5421 Automatic Biochemical Analyzer modules has advantages of good precision ,accuracy ,linear range ,and low cross-contamination rate .

Regulative mechanism of Chinese herbal medicine on cell signaling pathway in kidney / 中国中药杂志

In kidney, the role of cell proliferation, differentiation, apoptosis, inflammatory mediators and cytokines expression is closely related with cell signaling pathways, including tyrosine kinase pathway, transforming growth factor-beta/Smad pathway, Rho/Rho-associated coiled-coil forming protein kinase pathway, phosphoinositol pathway, cyclic nucleotide pathway, nuclear factor kappaB pathway and so on. Some Chinese herbs and their extracts, such as rhubarb and triptolide, as well as some Chinese herbal prescriptions, such as astragalus-angelica mixture and Chailing decoction, not only could ameliorate proliferation, differentiation and apoptosis of renal cell by regulating cell signaling pathways, but also could control target gene transcription, expression and its biological effects through inhibiting the phosphorylation of key signaling molecules.

Clinical significance of diversity of serum LAP during pregnancy / 临床检验杂志

Objective To explain the physiological properties of serum leucine aminopeptidase (LAP) and discuss the different levels and clinical meaning of serum LAP during the second and the third trimester of gestation.Methods Rate turbidimetry was used to assay serum LAP activity of 175 pregnant women in the second trimester of gestation, among whom 162 were normal and 13 were intrahepatic cholestasis of pregnancy (ICP), and 302 pregnant women in the third trimester of gestation, among whom 215 were normal, 76 were ICP, 6 were pregnancy-induced hypertension syndrome and 5 were premature delivery, and 100 healthy or non-pregnant women.Results Serum LAP activity of pregnant women in the group of the second trimester of gestation was (140.43?64.39) U/L, in the group of the third trimester of the gestation was (234.72?93.53) U/L, and in control group was (72.62?15.31) U/L. The serum LAP activities of the two pregnant groups were much higher than that of control group (P
