Objective To improve the methods of making myocardial ischemia-reperfusion model and observe the changes of electrocardiogram and ultrastructure of myocardium in rats.Methods The chest of young male SD rats through the fourth intercostal space was opened,and the left coronary artery was tied with a silicagel tube,after 30 minutes,untied to perfuse.Changes of electrocardiogram were observed and recorded.After reperfusion,the levels of AST,LDH,and CK-MB were measured and the tissue samples of the infarct areas were examined by transmission electronic microscope.Results The 90 percent of total rats were made myocardial ischemia reperfusion model successfully.In myocardial ischemia reperfusion rats:the QRS wave of myocardial ischemia-reperfusion rats was much higher than that of control group;the level of cardiac enzymes increased;myocardial and vascular endothelial cells ultrastructure was damaged seriously.Conclusions The improvement of modus operandi is right.Ischemia reperfusion can cause evident damage of myocardial and vascular endothelial cells ultrastructure in rats,and damage of myocardial cells is more severe than vascular endothelial cells.

Andrographis paniculata from different parts and origins were analyzed by UPLC-PDA fingerprint to provide refererice for related preparation technology. Using the peak of andrographolide as reference, 27 common peaks were identified, and digitized UPLC-PDA fingerprints for 23 batches of andrographis paniculata were established in this research. Principal component analysis (PCA) was carried out after feature extraction. The contents of andrographolide, neoandrographolide, deoxyandrographolide, dehydroandrographolide were determined by external standard method. The Plackett-Burman design combined with pareto chart was used to analyze the factors influencing the robustness of the method. It was found that the medicinal part has a more remarkable influence on the quality of andrographis paniculata than the origin. The contents of the 4 lactones the differ greatly in the different parts of andrographis paniculata, and the pH of the mobile phase is an important factor that influenced the robustness of the method.

The macroscopic characteristics, tissue, caterpillar body wall and powder of Ophiocordyceps xuefengensis in different batch numbers were observed and researched by the macroscopic and microscopic identification methods. The result shows that the morphology, size, abdominal annulations of caterpillar, etc. of 0. xuefengensis are the macroscopic identification characteristics, the caterpillar body surface mycelium, body wall sculpture and crochets on abdominal legs are the microscopic identification characteristics. These characters are stable and regular discriminant features, which are proved to be the identification basis of O. xuefengensis. In addition, The characters such as crochets on abdominal legs arrange in two parallel ellipse rings, the inner crochets are long strip, and the external toes are unciform, are specific.

AIM:To investigate the value of 3D-optical coherence tomography (OCT) in the diagnosis of macular disease before phacoemulsification.METHODS:Clinical records of 423 cataract patients (512 eyes) who underwent phacoemulsification combined with intraocular lens implantation in our hospital from June to December in 2015 were retrospectively analyzed.In addition to preoperative routine examination of fundus, Topcon 3D-OCT 2000 was used to examine the macula, the detection rate of macular disease was compared, risk factors of cataract combined with macular disease were analyzed.RESULTS:The OCT image results of 305 cases (384 eyes, 72.1%) were successfully obtained, 133 cases showed macular disease (146 eyes), the detection rate was 28.5% (95%CI:27.64%-29.40%);the macular disease of 35 cases (37 eyes) were detected by routine examination of fundus before operation, the detection rate was 7.2% (95%CI:6.72%-7.74%);the detection rate of 3D-OCT was significantly higher than routine examination of fundus for macular disease (χ2=79.05, P<0.01).Female, over 65 years old, surgical history of diseased eye, and high myopia were risk factors of cataract combined with macular disease, the relative risk was 1.705 (95%CI:1.091,2.664), 1.893 (95%CI:1.219,2.939), 6.593 (95%CI:2.027,21.447) and 95%CI:5.130 (2.841,9.263) respectively, the risk of cataract combined with macular disease showed an increasing trend with rising age.CONCLUSION:In preoperative examination of cataract patients, 3D-OCT has higher sensitivity in the detection of macular disease, especially for women, over 65 years old, high myopia and surgical history of diseased eye, 3D-OCT can be used as a routine preoperative examination.

ObjectiveTo determine the correlation between qualities of life(QOL) and depression,anxiety in cancer patients.Methods91 cancer patients was measured with self anxiety scale(SAS),self depression scale(SDS) and SF-36.ResultsDepression occurred in about 51.5% and anxiety occurred in about 24.1% of the general patients.The patients without depression showed a higher QOL than those with depression(P<0.05),and the patients without anxiety showed a higher QOL than those with anxiety(P<0.01).ConclusionDepression and anxiety are associated with poor quality of life,which should be put into plans of nursing.

OBJECTIVETo evaluate the effects of policosanol on serum lipid and heme oxygenase-1 (HO-1) in patients with hyperlipidemia.
METHODSThis randomized, open study included 72 patients with hyperlipidemia. The patients were randomly assigned to treatment group (policosanol, 20 mg/d, n = 36) or placebo group (placebo, two tablets/d, n = 36). The levels of serum lipids, hypersensitive C-reactive protein (hs-CRP), HO-1 were assessed before and after 16 weeks treatment. Drug-induced adverse effects and events were recorded during the observation period. The serum HO-1 was measured by ELISA.
RESULTS(1) After 16 weeks, all parameters remained unchanged in the placebo group; the level of TC decreased from (7.01 ± 1.03) mmol/L to (5.66 ± 0.83) mmol/L (-19.4%, P < 0.01), the level of LDL-C decreased from (4.78 ± 0.72) mmol/L to (3.70 ± 0.69) mmol/L (-22.5%, P < 0.01) in the treatment group. TG and HDL-C levels remained unchanged (P > 0.05) while the level of HO-1 significantly decreased from (1.82 ± 1.08) µg/L to (1.45 ± 0.81) µg/L (P < 0.01) and the level of hs-CRP decreased from (3.40 ± 3.64) mg/L to (1.86 ± 2.02) mg/L (P < 0.01) in the treatment group. (2) Safety index was similar between placebo and treatment groups (P > 0.05) and there was no adverse events including allergic reaction, muscle pain in all subjects during the observation period.
CONCLUSIONThe short-term data obtained from this small hyperlipidemia patient cohort suggest that policosanol is a safe lipid-lowering and anti-inflammatory agent for hyperlipidemia patients.

OBJECTIVESTo evaluate the effects of combined atorvastatin and probucol use on endothelial function in patients with acute coronary syndrome (ACS).
METHODSThirty patients with ACS were randomized to receive atorvastatin (20 mg/d) and probucol (500 mg/d, combination group, n = 15) or atorvastatin (20 mg/d) alone (atorvastatin group) within 24 h after admission for 4 weeks. Endothelium-dependent flow-mediated dilatation (FMD) and endothelium-independent sublingual nitroglycerin-mediated dilatation (NMD) as well as the levels of lipids and C-reactive protein were assessed at baseline, 1 week and 4 weeks after therapy.
RESULTSCompared to baseline, the levels of total cholesterol, LDL-C and C-reactive protein were significantly reduced after 1 week and 4 weeks in both groups, FMD equally increased after 1 week in both groups (atorvastatin group: 3.75% +/- 0.78% vs. 1.09% +/- 0.44%, combination group: 3.67% +/- 0.36% vs. 1.24% +/- 0.37%, P < 0.01). Post 4 weeks therapy, FMD increase was significantly higher in combination group (3.67% +/- 0.36% at 1 week vs. 6.85% +/- 0.64% at 4 weeks, P < 0.01) than that in atorvastatin group (3.75% +/- 0.78% vs. 3.80% +/- 0.31%, P = 0.954). NMD also equally and increased over 4 weeks in two groups (P < 0.01 vs. baseline). There was no correlation between the change in FMD/NMD and the changes in lipids or C-reactive protein levels.
CONCLUSIONSThe combined atorvastatin and probucol therapy early after ACS is superior to atorvastatin alone on improving endothelial function.
