This study established a population pharmacokinetics-pharmacodynamics model of clopidogrel in patients with acute coronary syndrome. Fifty-nine patients were enrolled. The plasma concentration of clopidogrel active metabolite and vasodilator stimulated phosphoprotein platelet reactivity index (VASP-PRI) were selected as the pharmacokinetics index and the pharmacodynamics index, respectively. The covariates including demographic characteristics, laboratory indexes, combined medication, complications and genetic polymorphisms of related enzymes were screened for their influence on the pharmacokinetic and pharmacodynamics parameters. Population pharmacokinetic and pharmacodynamics data analysis was performed using NONMEM software. The general linear model and the indirectly effect model-turnover model for pharmacokinetic and pharmacodynamic analysis were selected as the basic model, respectively. The population typical values of K12, CL/F, V/F, EC50, K(in), and E(max) were 0.259 h(-1), 179 L x h(-1), 632 L, 1.57 ng x mL(-1), 4.29 and 0.664, respectively. CYP2C19 was the covariate in the final pharmacokinetic model, and the model was to design a prior dosage regimen.

Objective:To investigate the expression and prognostic significance of CD19 in patients with Acute myelogenous leukemia with AML1-ETO positive. Methods: Clinical data of 66 patients AML with AML1-ETO positive who were newly diagnosed from Jan 2010 to Dec 2015 were collected. To retrospectively analyze the relationship between clinical characteristics and expression of CD19,so dose the prognosis. Results:The positive rate of CD19 expressing in AML with AML1-ETO positive was 50. 0%. There were no statistically significant differences in terms of age,gender,hemoglobin,platelet,percentage of bone marrow blasts,accompanied with chromosome ,gene mutations between patients with and without CD19 expression(P>0. 05). The white blood cell count(WBC) of the CD19 negative group was higher than CD19 positive group,while showed significant difference(P=0. 027). Although the relapse-free survival (RFS) of patients with CD19 expression was higher than those without,no significant difference was calculated (P=0. 105). Patients with CD19 expression had superior overall survival ( OS ) compared to those without CD19 expression ( P = 0. 030 ) . Multivariable analysis for OS identified CD19 positivity as an independent predictor associated with better prognosis. Conclusion: The expression of CD19 in AML with AML1-ETO positive may be an indicator associated with better prognosis.

Potassium metabolism in young adult men exercising in the heat for six consecutive days and the effect of potassium deficiency in mice and rats induced by low potassium diet during heat exposure were observed. Increased potassium loss in sweat and lower potassium intake resulted in negative potassium balance. Individuals with a negative potassium balance had lower se- rum potassium levels and higher body temperature after exercise. Potassium deficient mice accomplished less work done (2.372 vs 4.253 Kg.M) but exih-ibited a markedly greater rate of heat gain (1.36 vs 0.87℃/Kg.M) as compared to the controls. The survival rate and cellular energy metabolism also decreasedThese observations suggest that prevention from potassium deficiency must be emphasized during prolonged physical activity under hot environments. According to the linear regression equations between potassium intake and balance, it is proposed that the potassium requirements in mild and medium physical activity in the heat are 40 and 60 mEq/day respectively, and the allowance of potassium in the latter may be 70-80 mEq/day.

OBJECTIVETo investigate the inhibitory effects of phytosterols on abacterial prostatitis and discuss the possible mechanism.
METHODXiaozhiling-induced chronic prostatitis model were used to observe the inhibitory effect of phytosterols on abacterial prostatitis. The changes of serum IL-2, IL-1beta and TNF-alpha were evaluated by enzyme-linked immunosorbent assay (ELISA). The expression of COX-2 and 5-LOX were evaluated by Western blot and immunohistochemistry.
RESULTTreated by phytosterols (150 mg x kg(-1)), the number of white blood cells in xiaozhiling-induced chronic abacterial prostatitis rats was obviously decreased, the density of lecithin corpuscle in prostatic secretion increased and closed to control group. The edema, inflammatory infiltration of prostate were partly recovered compared with model group. The proliferation of chronic prostatitis were obviously decreased in phytosterols groups compared with model group in histological sections. Phytosterols could obviously reduce the serum IL-1beta, TNF-alpha, prostate COX-2 and 5-LOX expression and improve IL-2 level.
CONCLUSIONThese results demonstrated that phytosterols had good therapeutic effects on chronic abacterial prostatitis. Participation of immune regulation and inhibiting COX-2 and 5-LOX expression may be the mechanisms of action.
