Objective To explore the effects of ephedrine on the hippocampal cell apoptosis and behavioral performance after hypoxia-ischemia brain injury in neonatal rats.Methods Totally 90 7-day rats were randomly divided into 3 groups,ephedrine treatment group,model group,and sham group.Hypoxia-ischemia brain injury model was established by permanently ligating right common carotid artery.Ephedrine (1.5 mg/kg,once per day) was injected intraperitoneally to the rats of ephedrine treatment group for 7 d,and the rats of model group was given normal saline at the same volume.At the following time interval of 6 and 12 h,and 1,3,and 7 d after hypoxia,the expression of bcl-2 and bax were detected in the hippocampal region by immunohistochemical staining.At 4 weeks after surgery,behavioral changes in the remaining rats were tested by Morris water maze.Results Compared with model group,the expression of bcl-2 in the ephedrine treatment group was significantly increased after hypoxic-ischemic injury,peaked at 1 d and decreased in 3 d after operation.And the expression of bax in the ephedrine treatment group was decreased in 1 d after hypoxic-ischemia.The average time of escape latency was gradually decreased in each group.However,from the 3rd to 5th day,it was much shorter in ephedrine treatment group than in model group.In addition,the frequency platform passing in the ephedrine treatment group and the percentage of swimming distance traveled in the previous target quadrant was significantly greater than those of the control group.Conclusion Ephedrine upregulates bcl-2 and downregulates bax in the hippocampus of neonatal rats after hypoxia-ischemia,and improves their ability of learning and memory.

Purpose:To compare taxol,cisplatin(TP) and mitomycin, vinorelbine and cisplatin (MNP) with mitomycin,vindesine and cisplatin (MVP) and to evaluate the efficacy of the three regimens in patients with advanced non small cell lung cancer (NSCLC).Methods: One hundred and ten patients were enrolled in this study, 27 on TP, 40 on MNP and 43 on MVP. The characteristics of patients were comparable.Results:An objective response rate was observed in 51.9% of patients in the TP arm, 45.0% of patients in the MNP arm versus 32.6% in the MVP arm. The median duration of survival was 11.2 months in the TP arm, compared with 10.5 months in the MNP arm and 8.1 months in the MVP arm. The progression free survival was 9.0 months、8.0 months and 6.8 months in the TP、MNP and MVP arms, respectively. The major toxicities were bone marrow suppression、nausea、vomiting and alopecia.Conclusions:TP had a higher response rate than MNP and MVP, with acceptable toxicity. Its efficacy should be confirmed through a randomized study.

OBJECTIVE: To explore the effect of integrated pharmaceutical intervention on medication compliance, risk factors control, and 6 months and 2 years prognosis in patients with coronary artery disease(CAD) after first percutaneous coronary intervention (PCI) in china. METHODS: 200 cases of patients diagnosed with CAD and underwent PCI successfully firstly in Zhoupu hospital during January 2015 to December were enrolled. The control group was given routine treatment and nursing care; pharmacist intervention group, on this basis, was given pharmaceutical intervention by pharmacists, including optimizing medication program, formulating pharmaceutical care plan, medication education, health education and regular pharmacists outpatient follow-up. The two groups were followed up for two years. Comparison of the Readmission(Readm) rate, incidence rate of major adverse cardiac events (MACEs), Readm expenses, awareness rate of commonly used two-grade preventive drugs for CAD, medication compliance and emotion management after 6 months and two years in the two groups. The control of risk factors in the two groups after 2 years were compared. RESULTS: After six months, the Readm rate, the incidence of MACEs and Readm expenses in pharmacist intervention group were lower than those in the control group, and the medication compliance was slightly higher than the control group (94.9% vs 87.4%); two years later, the standard rate of risk factors in pharmacist intervention group was significantly better than the control group(smoking3.1% vs. 12.6%, P=0.012; blood glucose standard rate79.6% vs. 62.1%, P=0.007; blood pressure standard rate74.5% vs. 53.7%, P=0.003; blood lipid standard rate84.7% vs. 57.9%, P<0.001); and the Readm rate, the incidence of MACEs and the cost of Readm were significantly lower than those of the control group after six months and two years. CONCLUSION: Pharmacists′ active pharmaceutical intervention on patients after PCI can effectively improve the medication compliance of the patients, reduce the postoperative risk factors and the incidence of MACEs, reduce medical expenses, improve the clinical prognosis, which were more significant when the follow-up time was longer.

Objectives To evaluate the influences of age and sex on dose-response and recovery time course of atracurium. Methods Seventy-two patients (38 men and 34 women), ASA grade I, aged 15 ～ 59 years,scheduled for elective surgery were included in the study. All patients were divided into three groups according to their ages: Group 1, 32 patients aged 15 ～ 29 years; Group 2, 21 patients aged 30 ～ 40 years, and Group 3, 19 patients aged 41 ～ 59 years. General anesthesia was maintained with 60% nitrous oxide in oxygen, thiopentone and fentanyl. Neuromuscular function was assessed by train-of-four(TOF) stimulation of accelerometry and the percentage depression of the first response (T1) of the TOF stimulus was used as the study parameter. The dose-response relations of atracurium were determined by the cumulative dose-response technique. Results As compared to older and female patients, dose-response curves of atracurium in young and male patients were shifted in a parallel fashion to the left. The dose-response relation of atracurium correlated closely with patients′ ages and sexes by multiple linear regression analysis.There were significant differences of ED50、ED90 and ED95, and clinical duration and total duration of action following administration of atracurium of same doses between the three age groups as well as men and women. Conclusions Age and gender could significantly affect the pharmacodynamics of atracurium.

The incidence of liver disease is increasing year by year. Due to the complex predisposing factors and unclear pathogenesis of liver diseases, the cure rate is still not ideal, so it is urgent to clarify its mechanism to find more effective therapeutic targets and drugs. Long non-coding RNA (lncRNA), as a non-coding RNA with a length of more than 200 nt, is a research hotspot in liver diseases in recent years. Focusing on the main signal transduction pathways in liver diseases, this review mainly summarizes the latest research progress of lncRNA in regulating liver disease-related signaling pathways, and elaborates that lncRNAs participate in various physiological processes such as cell proliferation, apoptosis, invasion, and migration by regulating key signaling pathways in liver diseases, thereby promoting the occurrence and development of liver diseases. This review provides new ideas for studying the mechanism of liver diseases, and new directions for finding new targets and biomarkers for the treatment of liver diseases.

OBJECTIVETo investigate peripheral blood apelin levels in patients with acute ST-elevation myocardial infarction (STEMI) and their correlation with the one-year outcome of the patients.

METHODSA total of 153 consecutive patients, including 93 with acute STEMI undergoing primary percutaneous coronary intervention (PCI), 30 with acute STEMI and 30 with stable angina all undergoing elective PCI, and 10 healthy control subjects were examined for peripheral blood apelin levels and clinical parameters. The composite endpoints (CEPs) were determined at the one year follow-up.

RESULTSApelin levels were significantly decreased in all the patients at admission, but increased following primary PCI. Apelin levels showed a negative correlation with glycosylated hemoglobin levels. At one year following PCI, the patients with a lower apelin level showed an increased risk for lowered left ventricular ejection fraction ratio, but further analysis failed to provide evidence that apelin levels were predictive of the one-year outcome.

CONCLUSIONPeripheral blood apelin levels might be useful for predicting the clinical outcomes of patients with acute STEMI.

OBJECTIVETo investigate the association between Arg16Gly polymorphism of beta(2)-adrenergic receptor (ADRB2) gene and blood pressure levels.

METHODSA total of 487 hypertensive individuals were recruited from YueXi county of Anhui province. 672 patients' parents and siblings were also invited to take part in the study and used as genomic control. Blood pressure was measured and a standardized questionnaire regarding social-economic characteristics, general health status, occupational history and life-style and dietary factors was administered for each participant. The ADRB2 Arg16Gly polymorphism was genotyped by using a PCR-Restriction Fragment Length Polymorphism (RFLP) method. The association between the ADRB2 polymorphism and hypertension in hypertensive adults was determined by utilizing a family-based association test analysis.

RESULTSIn this study population, carriers of the ADRB2 Arg16 allele had lower systolic (P < 0.01) and diastolic (P < 0.01) blood pressure, suggesting that the genetic effect on blood pressure was more likely to fit an additive model.

CONCLUSIONOur results suggest a probable association between Arg16Gly polymorphism of ADRB2 gene and hypertension.

OBJECTIVETo investigate the expression of RRM1 and ERCC1 genes in tumor tissues and peripheral blood lymphocytes of advanced non-small cell lung cancer (NSCLC).

METHODSTissue and peripheral blood samples were collected from 49 advanced NSCLC patients treated with gemcitabine plus carboplatin. The expressions of RRM1 and ERCC1 mRNA in tumor tissue and peripheral lymphocytes were detected by real-time fluorescent quantitative PCR. The relationship of gene expression with clinical characteristics,chemotherapy response and prognosis was analyzed.

RESULTSThe RRM1 expression in tumor tissues was positively correlated with that in peripheral blood lymphocytes,while no significant correlation was observed between ERCC1 expression in tumor tissues and that in peripheral blood (rs=0.332 and 0.258; P=0.020 and 0.073, respectively). The expression of RRM1 and ERCC1 in tumor tissues peripheral lymphocytes was synchronous (rs=0.634 and 0.351; P<0.001 and 0.013, respectively). There was no significant correlation of gene expression with gender, age, smoking status, performance status, clinical stages and histological types of patients (P>0.05). Significant difference was found in response rate to chemotherapy (P<0.05,P<0.01,P<0.05),median survival time (P<0.05,P<0.01,P<0.05) and 1-year survival rate (P<0.01,<0.05,P<0.05) between patients with low RRM1 and ERCC1 expression levels in tumor tissues or low RRM1 expression levels in peripheral blood and those with high RRM1 and ERCC1 expression levels. The patients with low ERCC1 expression levels in tumor tissues gained higher 2-year survival rate (P<0.05). There was no correlation of the expression of ERCC1 in peripheral blood with the response to chemotherapy and prognosis (P>0.05).

CONCLUSIONThe expression of RRMI and ERCC1 genes in tumor tissues and RRM1 in peripheral blood lymphocytes is closely correlated with the response to chemotherapy and prognosis of patients with advanced NSCLC treated with gemcitabine plus carboplatin.
