ObjectiveTo provide a reference for the establishment and appliance of enzyme reference measurement of CK in China by comparing and analyzing the RELA results of CK in IFCC from 2006-2008. Methods The RELA samples of CK were measured according to the reference procedure for the measurement of catalytic activity concentration of CK (37 ℃) ,which had been published by IFCC. The EP5A2 protocol was used for evaluation of the imprecision and ERM was used for verification of the trueness. Results In RELA 2006, the result of sample A was (9. 896 ±0. 112) μkat/L, and the result of sample B was (4.953 ±0. 120) μkat/L. In RELA 2007, the result of sample A was (2.684 ±0.054)μkat/L, and the result of sample B was (8.798 μ0. 101) μkat/L. In RELA 2008, the result of sample A was (10. 523 ±0. 149) μkat/L,and the result of sample B was (10. 551 ±0. 141) μkat/L. The precision of the CK reference method in the year 2006 to 2008 was 0. 92%, 0. 86% and 0. 88% respectively, each of them is less than 1% and the results of ERMs were consistent with the certified value(1. 68 ± 0. 07)μkat/L,which verify the imprecision and accuracy of the reference method. Conclusions All of the results in the continuous three years were in the range of equivalence limits suggested by IFCC. The CK reference method suggested by IFCC has been established and it is getting better.

Aim To further investigate the protective effect and mechanisms of total paeony glycoside (TPG) on apoptosis in experimental myocardial ischemic rats.Methods The myocardial ischemic model of rats was established by subcutaneous injection of isoprenaline (ISO), and early apoptosis rate of myocardial cells and the expression of apoptosis related genes Bax, Bcl-2 and proteins in myocardial tissues were analyzed and contrasted among five groups, including normal control, ISO injury, TPG prevention and treatment, TPG treatment and positive control.Results Compared with ISO injury group, all of indexes had improved in various degrees in TPG prevention and treatment group and TPG treatment group, such as the decrease of early apoptosis rate,expression of Bax gene and protein, the increase of Bcl-2 gene and protein and the ratio of Bcl-2 protein/Bax protein.Conclusion TPG has protective effect on apoptosis in ischemic myocardium induced by ISO.The pharmacological mechanism may relate to the activation of the Bcl-2 gene and protein expression, the inhibition of Bax gene and protein expression, as well as the increase of Bcl-2/Bax ratio.

Objective] To summarize national famous doctor of traditional Chinese medicine-Wu Liangcun ’s experience about the clinical treatment of ovarian cancer. [Method] By studying and following Professor Wu Liangcun to diagnose, this paper discusses Professor Wu ’s academic views and clinical experience of diagnosis and treatment of ovarian cancer respectively from the aspects such as etiology and pathogenesis, and treatment based on syndrome differentiation. It expounds the characteristics of his prescription and also gives proven cases. [Result]Professor Wu Liangcun proposes that the pathogenesis of ovarian cancer is mainly congenital deficiency and physical weakness resulted from cold coagulation, qi stagnation, blood stasis and phlegmatic hygrosis. All these remain a standstill, gather together and become a disease. He uses the syndrome differentiation method to divide the common ovarian cancer into four types:blood stasis and vital energy retardation, phlegm dampness condensation, deficiency of liver-yin and kidney-yin, asthenia of qi and blood. In the treatment, he organically combines the dialectics and the differentiation of disease; In the selection of drugs, he streamlines the prescription and the drug, which maximizes the efforts of the drugs and has good efforts in clinic.[Conclusion] Professor Wu Liangcun is good at making a diagnosis and giving treatment of ovarian cancer in combination with disease and syndrome, and he uses medicine flexibly. It has a very good effect and practical value for guiding clinic, and it should be promoted.

To induce immune tolerance in recipient rats of allogenic heart transplantation with hydrocamptothecin (HCPT) and cyclosporin A (CsA) and to study the mechanisms of the tolerance, inbred SD rats were chosen as heart donors and Wistar rats as recipients. After transplantation, the recipients were treated with HCPT and/or CsA. The level of cytokine expression was assessed using RT-PCR. The results showed 3 of 10 heart grafts in group C (HCPT 2. 0mg) and 5 of 10 in group E (HCPT+CsA) survived longer than 730 days even immunosup-pression agents (HCPT and CsA) were withdrawn on day 60 after transplantation. Immune tolerance was verified by challenge with SD and SHR rat skin. The levels of IL-2 and IFN-? rnRNA expression were significantly lower in the grafts of tolerant rats than in those of rejected rats, The levels of IL-4 and IL-10 mRNA were significantly higer in the grafts of tolerant rats than in those of rejected rats. The level of cytokine mRNA expression in the grafts was similar to that in spleen of recipients. Our conclusions is high or low dosage of HCPT combined with CsA could induce tolerance in allogenic heart transplantation in rat recipients. Cytokine deviation is one of the mechanisms in allogenic heart transplantation immune tolerance induced by hydrocamptothecin.

Objective To investigate the effects of 5-Aza-2'-deoxycytidine (5-Aza-dc),a methylation inhibitor,on the proliferation of androgen-sensitive prostate cancer line (LNCaP),and on its regulation of methylation on glutathione s transferaseP1 (GSTP1) and retinoic acid receptorβ2 (RARβ2) gene.Methods LNCaP cells were treated with 5-Aza-dc in different concentration,CCK8 method was used to detect the growth of LNCaP cells.The methylation of GSTP1 and RARβ2 gene in LNCaP cell was detected by nested methylation specific polymerase chain reaction (nMSP).Results The proliferation of LNCaP cells was inhibited after exposed to 5-Aza-dc.The methylation of GSTP1 and RARβ2 gene was changed from hypermethylation to demethylation by the 5-Aza-dc.These effects were dose-and time-dependent within certain concentration of 5-Aza-dc,but LNCaP cells grew better after 72 h than within 48 h when exposed to 5 Aza dc below 1.0 μmol/L.Also the methylation of GSTP1 and RARβ2 gene changed from hypermethylation to demethylation by the 5-Aza-dc was not different when exposed to 5-Aza-dc below 1.0 μmol/L within 72 h and 48 h.Conclusions 5-Aza-dc may effectively inhibit the growth of LNCaP cells and reverse the DNA methylation damage in some tumor suppressor genes,but the continuity and stability of low dose 5-Aza-dc is changeable.The study will provide a research basis for clinical treatment.

Objective To evaluate the appropriateness of hospitalization days at a tertiary hospital in 2014 by means of the Appropriateness Evaluation Protocol ( AEP ) , and to analyze the causes of inappropriate stays. Methods Medical records of inpatients admitted at a tertiary hospital in 2014 were randomly selected. AEP( US version) was used to evaluate the appropriateness of every hospitalization day, while the causes of inappropriate hospitalization day were also analyzed. Results A total of 1 641 days of stay from 148 medical records were reviewed, and 129 days of stay (7. 9%) were seen as inappropriate. Two major factors for inappropriate stays were waiting for surgery and waiting for test, roughly 89. 1% of the inappropriate hospitalization days. The proportion of inappropriate hospital stays reduced to 4. 8% after adjustment of two-day weekend. Inappropriate hospital stays mostly appeared during the second day to the eighth day after admission(93. 8%). Logistic analysis results showed that with concomitant symptoms, preoperative waiting days > 5 days, high level surgery, non-emergency admission were significantly associated with appropriateness of hospital stays (P<0. 05). Conclusions The rate of inappropriate stays will be reduced and the quality of medical services will be improved if comprehensive measures could be carried out according to the causes of inappropriate stays.
