OBJECTIVE:To investigate the clinical efficacy of alprostadil combined with edaravone in the treatment of unsta-ble angina pectoris(UAP),and their effects on serum oxidative stress indexes,the levels of MMP-2 and MMP-9. METHODS:Be-sides conventional treatment,control group was treated with Alprostadil injection 2 ml added into 0.9% Sodium chloride injection (NS)100 ml,ivgtt,qd;while observation group was additionally treated with Edaravone injection 15 ml added into NS 100 ml, ivgtt,qd. Treatment courses of 2 groups lasted for 2 weeks. The frequency and duration of UAP attack,serum levels of MDA, SOD,TAC,MMP-2 and MMP-9 levels were observed 2 groups;the occurrence of ADR was also observed. RESULTS:There was no statistical significance in frequency of angina pectoris attack,duration,MDA,SOD,TAC,MMP-2 and MMP-9 between 2 groups before treatment (P>0.05). After treatment,the total effective rate of observation group (94.3%) was significantly higher than that of control group(81.4%). The frequency of angina pectoris attack and the level of MDA,were significantly reduced,and the duration of angina pectoris was significantly shortened SOD and TAC increased significantly;the change of observation group was more significant than that of control group with statistical significance(P<0.05). ADR was mild in 2 groups;there was no statisti-cal significance in the incidence of ADR(P>0.05). CONCLUSIONS:Alprostadil combined with edaravone is significantly effec-tive for UAP,reduces the frequency of angina,shortens the duration of angina pectoris,alleviates oxidative stress and reduces se-rum levels of MMP-2 and MMP-9 with good safety.

Objective To investigate the clinical value of the peripheral blood monocyte human leukocyte antigen-DR (mHLA-DR) for assessment of degree of severity and the diagnosis of acute pancreatitis (AP). Methods A case-control study was conducted. Eighty-six AP patients admitted to Shandong Liaocheng People's Hospital from June 2014 to May 2015 were enrolled. Patients were classified into four groups [mild (n = 33), moderate (n = 25), severe (n = 16), critical (n = 12)] according to the disease classification. Eighty healthy persons subjected to physical examination center of our hospital at the same time were served as controls. Acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) scores in patients were estimated. Flow cytometry was used to measure the expression of the peripheral blood mHLA-DR, and the Pearson method was used to analyze the relationship between the level of mHLA-DR and the APACHE Ⅱ score. The receiver-operating characteristic curve (ROC) was plotted, and then the clinical value of the peripheral blood mHLA-DR was analyzed for the diagnostic value in AP patients. Results The expression of the mHLA-DR in patients with AP was significantly lower than that of healthy control group [(63.7±18.6)% vs. (86.4±8.3)%, t = 5.319, P < 0.001]. The expression levels of the mHLA-DR in mild group, moderate group, severe group, and critical group were (79.6±6.5)%, (66.4±9.4)%, (49.9±8.1)%, (32.5±12.0)%, respectively, and the APACHE Ⅱ score were 4.67±1.99, 5.88±2.05, 9.06±2.62, 12.33±3.96, respectively. Pair wise comparisons were statistically significant (all P < 0.05). The HLA-DR expression level in the peripheral blood of patients with AP was negatively correlated with the APACHE Ⅱ score (r = -0.695, P < 0.001). The area under the ROC curve (AUC) of mHLA-DR expression in peripheral blood for AP was 0.894 [95% confidence interval (95%CI) = 0.847-0.941, P < 0.001], and the cut-off point was 84.40%, with the sensitivity of 75.0%, the specificity of 90.7%, and the accuracy rate of 83.1%. The AUC of mHLA-DR expression for mild AP was 0.938 (95%CI = 0.889-0.987, P < 0.001), and the cut-off point was 72.70%, with the sensitivity of 87.9%, the specificity of 88.7%, and the accuracy rate of 88.4%. The AUC of mHLA-DR expression for severe and critical AP was 0.943 (95%CI = 0.881-1.005, P < 0.001), and the cut-off point was 57.85%, with the sensitivity of 84.0%, the specificity of 96.4%, and the accuracy rate of 90.6%. Conclusions The expression levels of the peripheral blood mHLA-DR in AP patients can reflect the degree of disease, and contribute to the diagnosis of AP. The value of mHLA-DR may be used as a new biological indicator in the diagnosis and assessment for the severity of AP.

Aim To investigate the induction effect of ginsenoside Rc, Re, Rf and Rg1 on CYP1A1, and further validate the role of aryl hydrocarbon receptor in CYP1A1 expression. Methods Dual luciferase re-porter gene system was performed. Four kinds of gin-senoside were screened for aryl hydrocarbon receptor activation by reporter assays, and TCDD as the positive control. Further with different concentrations of ginsen-oside Rc, Re, Rf and Rg1 treated on LS174T cells, RNA and total protein were extracted to detect the reg-ulating effect of ginsenosides on CYP1 A1 mRNA and protein expression with Real-time PCR and Western blot technology respectively. Results Reporter gene screening showed that the ginsenoside Rc, Re, Rf and Rg1 could activate AhR and had potential effects on the induction of CYP1A1 enzyme. Meanwhile, dose-de-pendent induction of the gene expression were observed in response to ginsenoside Rc, Re, Rf and Rg1 and the levels of CYP1 A1 protein expression were increased by ginsenoside Rc, Re, Rf and Rg1 in varying de-grees. Conclusion Ginsenoside Rc, Re, Rf and Rg1 can up-regulate the gene and protein expression of CYP1 A1 possibly via the AhR-mediated CYP1 A1 path-way.

Objective:To explore the clinical characteristics, mechanism and countermeasures of drug-induced second thrombocy-tosis ( ST) in order to ensure safe medication. Methods:Drug-induced ST published during 1996 and 2016 in domestic and overseas medical journals was collected and statistically analyzed in respects of age, gender, kind and distribution of drug-induced ST, treatment and outcome of ST. Results:Totally 198 cases were collected, which involved 30 different drugs of eight types mainly including antitu-mor drugs, blood system drugs and antibiotics. Among the patients, 112 ones (56. 6％) were male and the other 86 ones (43. 4％) were female. Totally 14 patients had embolization with the overall incidence of 7. 0％. Conclusion:Without timely and favorable treat-ment, drug-induced ST may lead to thrombosis. To ensure the safety of medication, platelet level should be monitored regularly during medication.
