Objective To study on effects of Alprostadil on 24-hour urinary albumin(U-Alb)in patients with diabetic nephropathy.Methods:38 patients with diabetic nephropathy were included in the study.The test group involving 20 patients were grouped into group A(pristine diabetic nephropathy) and group B(clinical diabetic nephropathy)randomly according to urinary albumin.The control group including 18 patients were grouped into two groups according to the same way.The subjects in both groups have the same therapy in terms of control of blood glucose,blood pressure,plasma lipids,and other therapy methods.Besides,the test group was injected Alprostadil(凯时)10ug from vein,one time a day,14 day continuously,but Alprostadilas well.Results After the treatment of two groups,the level of the urinary albumin decreased obviously compared with the index before treathent,and decreased significantly compared with normal control group.Conclusion Alprostadil can lower urinary albumin with diabetic nephropathy.

Cloning and identification of differentially expressed genes or proteins is helpful not only for finding the functions of genes and proteins, but also for discovery of the mechanism of some diseases. Some methods have been developed for screening differentially expressed genes, such as differential display RT-PCR (DDRT PCR), subtractive hybridization (SH), DNA chip technique, and serial analysis of gene expression (SAGE). In subtractive hybridization, there have advanced three improved methods which include representational difference analysis (RDA), suppression subtractive hybridization (SSH), and full-length-gene-obtainable subtractive hybridization. For obtaining differentially expressed proteins, scientists have only two choices so far. One is two-dimentional gel electrophoresis. The other is phage display antibody repertoire library technique. Since all of the methods above have their own advantages and disadvantages, they should be used according to different needs.screening, differentially expressed genes, differentially expressed proteins

Objective: To investigate changes of plasma glucagon level in patients with heart failure (HF) caused by coronary heart disease (CHD) and its clinical significance. Methods: A total of 30 HF patients caused by CHD were selected as HF group, another 30 healthy subjects with corresponding age and gender were regard as normal control group. HF patients received comprehensive therapy of enhancing myocardial contractility, diuretic and vasodilator of 7~10d according to Chinese diagnostic and treatment guideline of chronic heart failure. Changes of glucagon level before and after treatment were observed. Results: Before treatment, plasma level of glucagon in HF group was significantly higher than that of normal control group [(205.67±120.22) ng/L vs. (90.53±20.5) ng/L, P<0.05]. After treatment, plasma level of glucagon [(120.42±30.33) ng/L] significantly decreased than before treatment (P<0.05) in HF group. Conclusion: Plasma glucagon significantly increases in patients with heart failure and gradually decreases to near normal level after treatment. Glucagon level may be regard as one of indexes judging patients’ condition.

OBJECTIVE:To provide reference for the development of clinical pharmacists’career and the establishment of le-gal system in China. METHODS:The background,progress and situation of applying for“pharmacists’health care provider sta-tus”in the United States were introduced. The reasons for achieving provider status in California,Washington,and Oregon were summed up in aspects of politics,economics and education. The chance and challenge for achieving provider status at federal level were also discussed. Based on the development of clinical pharmacists in China,the suggestions were put forward for the improve-ment of legal system of clinical pharmacists in China. RESULTS & CONCLUSIONS:“Health care provider status”in the United Stated were recognised by 3 states with local developed economics,high-level education,and collective efforts of pharmacy organi-zations. Multiple national pharmacy organizations as American Pharmacists Association,American Society of Health-System Phar-macists and American Pharmacy College Society are working together toward provider status at the federal level. Our country should pay attention to related legal system construction,establish perfect and definite clinical pharmacists legal system as soon as possible to provide legal guarantee for career development of clinical pharmacists in China.

Objective To explore the characteristic and clinical meaning of myocardial bridge in patients with multi-slice spiral CT(MSCT) coronary angiography.Methods 875 patients with suspected or diagnosed coronary artery disease were studied with MSCT coronary angiography,579 cases were male and 296 cases were female,ranged from 30~87 years old in age with average of 60 years old.The heart was scanned with retrospectively ECG-gated,reconstruction from phase for all original tomographic source images at 30%~40% R-R phase interval according to heart rate ≥75 bpm and at 40%~50% R-R phase interval according to heart rate ≤75 bpm.The images of maximum intensity projection,multiplanar reconstruction and vulume reconstruction were gained to show left and right main coronary artery and their main branchs on mulliple angle.Results The myocardial bridges were detected in 89 cases,the positive rate was 10.2%,36 cases(40.5%)had different grade stenosis(≤50%).The myocardial bridges located at middle segment of anterior descending artery(79.8%),the thickness of myocardial bridge was 0.06~0.55 cm,the atherosclerosis plaques were found in 20 cases,the vascular stenosis was approximate to 50%.39 cases with simple myocardial bridges had angina,21 cases hadn’t angina.23 cases with myocardial bridges accompanied by coronary artery atherosclerosis had angina.Conclusion MSCT coronary angiography may clearly detect the myocardial bridge,which can provide more worthy information for clinical diagnosis and treatment.

Objective To study the sensitivity and reliability of rat skin anaphylactoid test method, detect and evaluate the anaphylactoid reaction of traditional Chinese medecine injection. Methods The condition of rat skin anaphylactoid test was optimized by studying the influencing factors of sensitivity and reliability of test with C48/80 as a tool drug, Tween80, endotoxin, China cobra toxin, trichosanthin injection, Tanreqing injection and Xuesaitong injection were investigated. Results The best conditions of rat skin anaphylactoid test was as follows:intrademal inject the drug with insulin syringe, 50-100μL per point, immediately inject 0.5%Evans blue dye 1 mL though caudal vein, 15 min later, kill the rat by carotid artery bleeding, clip dorsal skin to do the test. With this method, Tween80, endotoxin, China cobra toxin and trichosanthin injection all can induce blue stain in rat skin. Tanreqing injection showed no blue stain at the clinical dose. Xuesaitong injection although can induce blue stain in rat skin at the clinical dose, but the results cannot exclude the interference of its pharmacological function. Conclusion The method is simple with short test cycle, less dose of test drug, high detection sensitivity and good reproducibility, but some drug can show false positive result due to its own property.

AIM To evaluate the beneficial effects of isoliensinine on paraquat(PQ)-induced acute lung injury and pulmonary fibrosis and explore the mechanism of its action. METHODS PQ (45 mg·kg-1, ip)-induced acute lung injury and PQ (100 mg·kg-1, ig)-induced pulmonary fibrosis were prepared. At 8, 24 and 48 h after PQ administration, the effects of isoliensinine (20 mg·kg-1, ig, 3 times a day, from 24 h before PQ administration to the end of experiment) on activity of superoxide dismutase (SOD), alkaline phosphatase (ALP) and the content of malondialdehyde (MDA) in plasma and bronchoalveolar lavage fluid (BALF) of acute lung injury groups were evaluated respectively. On the 14 d following PQ ingestion, the effects of isoliensinine (10, 20 and 40 mg·kg-1, ig, twice a day, from 24 h before PQ administration to the end of experiment) on hydroxyproline content, transforming growth factor β1 (TGF-β1) and matrix metalloproteinase-2 (MMP-2) expressions and the histopathological changes in lung tissues of pulmonary fibrosis groups were observed. RESULTS In the acute lung injury model, isoliensinine (20 mg·kg-1) significantly increased SOD activity, and decreased MDA content and ALP activity, as well as ameliorated the histopathological damage of lung tissue compared with PQ group. However, the indexes mentioned above in isoliensinine alone group did not change obviously compared with normal saline group. In the pulmonary fibrosis model, isoliensinine (10, 20 and 40 mg·kg-1) resulted in a dose-dependent decrease of hydroxyproline content compared with PQ group [(2.11±0.21), (1.94±0.24) and (1.89±0.26), respectively, vs (2.44±0.33) mg·g-1 wet tissue]. The expressions of TGF-β1 and MMP-2 in the lung tissue of the isoliensinine 40 mg·kg-1+PQ group were significantly less than those of the PQ group. Furthermore, isoliensinine could improve the histopathological changes of fibrosis as comparison with PQ group. CONCLUSION Isoliensinine has protective effects on PQ-induced acute lung injury and pulmonary fibrosis.
