Objective:To investigate the effect of atorvastatin on the blood lipid and uric acid levels of elderly patients with coronary heart disease complicated with diabetes mellitus.Methods:116 patients with coronary heart disease and diabetes were randomly divided into the control group and the experimental group,58 cases in each group.Both groups of patients were given blood glucose control,blood pressure and other symptomatic treatment.The control group was treated with Aspirin Enteric-coated Tablets 0.3～0.6 g/times,3 times/d,oral,clopidogrel tablets,2 tablets each time,1 time/d,oral,nitroglycerin,0.25～0.5 g/time,3 times/d,with service;the experimental group was given atorvastatin on the basis of control group,10～20 mg/time,1 time/d,treatment for 4 weeks.During the treatment,the dosage was timely adjusted according to the conditions of patients.The serum low density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol (HDL-C),triglyceride (TG),total cholesterol (TC),uric acid (UA),glycosylated hemoglobin (HbA1c) levels before and after treatment and the clinical treatment efficiency were observed and compared between two groups.Results:Compared with before treatment,the serum LDL-C,TG,TC,UA,HbA1c levels were decreased ahter treatment in both groups of patients,the HDL-C level was increased (P＜0.05);compared with the control group,the serum LDL-C,TG,TC,UA,HbA1c levels were lower,HDL-C level was higher in the experimental group (P＜0.05);compared with the control group,the effective rate of clinical treatment of the experimental group were higher (P＜0.05).Conclusion:Atorvastatin could effectively reduce the blood glucose,blood lipid,uric acid levels of elderly patients with coronary heart disease complicated with diabetes.

The paper is to report the pharmacokinetics of furosemide in rats living at plain area and high altitude. After intragastric administration of furosemide (2.87 mg x kg(-1)), serial blood samples (0.5 mL) were collected by retro-orbital puncture at 0, 20 min, 40 min, 1, 1.5, 2, 3, 4, 6, 8, 12 and 24 h, samples were determined by LC-MS/MS, and plasma concentration-time data were analyzed by DAS 2.0 software to get the related pharmacokinetic parameters. The main pharmacokinetic parameters: area under curve (AUC), mean residence time (MRT), the biological half-life (t1/2) and the peak concentration (C(max)) of furosemide, were significantly increased at high altitude, the time to reach peak concentration (t(max)) and clearance (CL) was significantly decreased. This study found significant changes on the pharmacokinetics of furosemide under the special environment of high altitude. This finding may provide some references for clinical rational application of furosemide at high altitude.

In this paper, a series of low-molecular-weight PEG-PCL-PEG triblock copolymers were successfully synthesized by ring-opening polymerization method, and were characterized using 1H-NMR and FTIR. The aqueous solution displayed specific thermosensitive gel-sol transition when the concentration was above corresponding critical gel concentration (CGC). The gel-sol phase diagram was recorded using test tube-inverting method, which was depended on the hydrophilic/hydrophobic balance in macromolecular structure, as well as heating history. As a result, the gel-sol transition temperature range could be altered, which might be very useful for its application as injectable drug delivery system.

OBJECTIVE To explore the role of the establishment of the trans-regional review system on rational drug use in second-grade general hospital ，and to promote the rational drug use. METHODS With the administrative support of Jiuquan Health Commission，5 second-grade general hospitals in Jiuquan Medical Association jointly established Jiuquan Rational Drug Use Review Training Center . A trans-regional review system was established to carry out cross-review of prescriptions and medical orders among 5 second-grade general hospitals. Totally 1 500 prescriptions and 900 medical records were collected from 5 second-grade general hospitals before （April to June ，2020）and after （July to September ，2020）the implementation of the project. The changes of rational drug use indicators ，the results of prescriptions and medical order review were investigated before and after the implementation of the project. RESULTS After the implementation of the project ，except for one hospital ，the proportion of drugs in other hospitals decreased to varying degrees with the highest decline rate of 22.56％ . Compared with before the implementation of the project ，reasonable rate of outpatient and emergency prescription review increased by 5.72％ averagely and the reasonable rate of medical order review increased by 10.10％（P＜0.05）. The average utilization rate of antibiotics in outpatients decreased by 14.45％，the average utilization rate of antibiotics in inpatients decreased by 7.98％，and the average use intensity of antibiotics decreased by 25.19％. CONCLUSIONS Through the establishment of trans-regional review system ，medical institutions can be forced to pay more attention to prescription review ，effectively improve the prescription review of pharmacists in medical institutions，and promote the rational use of drugs in medical institutions in the region. However ，there are still some problems ， such as incomplete system coverage ，insufficient work experience ，lagging of informatization ，uneven pharmacist level ，and insufficient assessment and supervision of administrative functional departments.
