OBJECTIVE:To observe therapeutic efficacy and safety of domestic Imatinib mesylate tablet in the treatment of chronic myeloid leukemia(CML). METHODS:16 CML patients were selected,including 7 newly diagnosed CML patients and 9 patients diagnosed as CML more than 12 months. Imatinib mesylate tablet 400 mg,qd were used in all patients. Blood routine, bone marrow cytology,ph chromosome Evaluate efficacy,and observed peripheral blood fusion gene,Bcr-Abl/Abl gene mutation and ADR were all detected. RESULTS:After treatment,16 patients achieved complete hematologic remission (CHR);12 cases were pavtial cytogenetic response(MCyR),of which 2 cases achieved complete cytogenetic response(CCyR),2 cases were cyto-genelic remission. 15 patients'Bcr-Abl/Abl transcript levels were less than 10%,and only one case was more than 10%. No ADR difficult to tolerate was found in 16 patients. CONCLUSIONS:Domestic Imatinib mesylate tablet shows definite early therapeutic efficacy and high safety.

Objective To investigate the incidence and the relation between pulmonary hypertension (PH) and cardiac output in hemodialysis (HD) patients with PH. Methods The incidence of PH was estimated with Doppler echocardiography in 78 patients receiving HD. Left ventricular ejection fraction, cardiac volume, cardiac output and cardiac index were compared between patients with or without PH. Results PH was found in 20 patients (25.64%), among them15 had mild PH, 4 had moderate PH and 1 had severe PH. There was no statistical difference of ejection fraction, cardiac volume, cardiac output and cardiac index between the two groups. PH was not related to cardiac output. Conclusion HD can lead to PH, but cardiac output can not result in PH. Further investigations about the effect of elevated cardiac output induced by internal arteriovenous fistula and other factors on PH are needed.

Objective To investigate the comparability of the activity detection of 6 common serum enzymes by different bio-chemical detecting systems at the same laboratory to provide the basis for realizing the traceability and comparability of serum en-zyme detection.Methods The detection system consisted of the Hitachi 008 biochemical analyzer,and original reagents,C-fas cali-brator and controller of Roche was taken as the reference system X(comparison method)and the detection system consisted of the ABBOTT ARCHITECT C16000 biochemical analyzer,reagents and calibrator of Zhongsheng,and controller of BIO-RAD was taken as the detecting systemY (laboratory method),which were used to detect the accuracy and precision of fresh serum enzymes inclu-ding ALT,AST,ALP,GGT,LDH and CK according to the NCCLS document EP9-A2.Then the enzyme activity results detected by the Y and X methods were compared and the relative error(SE%)was calculated.The comparability of the results detected by these two kinds of different detection systems was judged with 1/2 of allowable error in the external quality assessment stipulated by CLIA′88 as the standard.Results The accuracy and precision of the activity detection results of 6 enzymes by the Hitachi 008 and ARCHITECT C16000 biochemical analyzers all conformed to the requirements and the systematic error was clinically acceptable. Conclusion In measuring same test item by two or more detection systems,the method comparability and the bias assessment should be performed for ensuring the accuracy and comparability of the detection results.

This study is to investigate the effect of artesunate on transforming growth factor-beta1 (TGF-beta1) induced epithelial-mesenchymal transition (EMT) and its possible mechanism. After the in vitro cultured RLE-6TN cells were treated with TGF-beta1 then artesunate intervened on it, after 24 h, expression of the markers of mesenchymal cell was assayed using Western blotting and real-time PCR analysis. Western blotting was also used to detect the effect of TGF-beta1 on the Smad3 and Smad7 expressions of RLE-6TN cells. Morphological alterations were examined by phase-contrast microscope, and ultrastructure changes by electron microscope. Incubation of RLE-6TN cells with TGF-beta1 resulted in the up-regulation of the expression of the mesenchymal cell markers, after artesunate intervened on it, resulted in the down-regulation of the expression. Meanwhile, incubation with artesunate intervened on RLE-6TN cells could lead to the apparent down-regulation of the expression of Smad3 and up-regulation of Samd7 and the transition of RLE-6TN cells to mesenchymal-like by TGF-beta1 induction, after artesunate intervened on it, RLE-6TN cells to epithelial-like. TGF-beta1 induced epithelial-mesenchymal transition process; artesunate can inhibit TGF-beta1-induced epithelial-mesenchymal transition process, the possible mechanism is up-regulation of the expression of Smad7 and down-regulation of the expression of Smad3, meanwhile inhibits phosphorylation of Smad3.
