In this study, modification technology by surface coating was used to improve the flowability of powder of Chinese herbs extracts. Seven kinds of powder of Chinese herbs extracts were coated with 1% silica nanoparticles using an under-driven Comil. The powder characteristics tester was used to evaluate the flowability of uncoated and coated powders. Surface morphology and particle size distribution of powders were compared by scanning electron microscope (SEM) and optical microscope. The powder hygroscopicity was also investigated. The results showed that, after modification, angle of repose, angle of spatula, compressibility and adhesiveness extremely decreased, and flowability index substantially increased, the powder flowability was significantly improved, especially Gegen and Dahuang extracts powders. Scanning electron microscopy images showed the distribution of silica nanoparticles on the host drug particle surfaces. There were no remarkable changes in the particle size distribution and hygroscopicity of all powders after coating. Therefore, Comilling for surface coating modification technology was an effective method to improve the flowability of Chinese herbs extracts and suggested a possible way forward to enhance the quality of Chinese drugs pharmaceutics in their study and manufacture.

Objective: To explore the influencing factors of slow blood flow phenomenon after emergency percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Methods: Clinical and PCI angiographic data of 488 patients, who were diagnosed as AMI and received primary PCI in our hospital from Jan 2010 to Jun 2011, were retrospectively analyzed. Patients were divided into slow blood flow group (n=51, TIMI flow ≤ grade 2) and normal flow group (n=437, TIMI flow= grade 3). Their clinical characteristics between two groups were compared. Results: Compared with normal flow group, there were significant reductions in percentages of thrombus aspiration (75.3% vs. 60.8%) and application of platelet glycoprotein IIb/IIIa receptor antagonist (81.7% vs. 68.6%) during PCI, and significant rise in total length of implanted stents [(31.8±12.2) mm vs. (35.7±12.0) mm] in slow blood flow group, P<0.05 all. Multi-factor Logistic regression analysis indicated that percentages of thrombus aspiration during PCI and total length of stents were independent influencing factors for slow blood flow (P<0.05 both). Conclusion: Percentages of thrombus aspiration and total length of stents during PCI are independent influencing factors for slow blood flow.

The expressions of Ki67 and FHIT were detected by immunohistochemical staining in 15 cases of adrenocortical carcinoma, 42 cases with adrenocortical adenoma,6 cases of adrenocortical hyperplasia, and 10 cases of normal adrenocortical tissue. The results showed that the highest expression of Ki67 and the lowest expression of FHIT were found in adrenocortical carcinoma. There were significant differences in the Ki67 and FHIT between adrenocortical adenoma and adrenocortical carcinoma ( both P < 0. 05 ). There existed negative correlation between the expressions of Ki67 and FHIT( r=-0. 712, P<0.05 ). Ki67 over-expression and loss of FHIT expression may be involved in the occurrence and development of adrenocortical carcinoma. It is suggested that combined detections of Ki67 and FHIT may have reference significance in the differentiation of adrenocortical adenoma from adrenocortical carcinoma.

OBJECTIVETo study the protective effects of ofloxacin by reduction of endotoxin on lung in rats with hepatopulmonary syndrome (HPS).

METHODSRat models of HPS were induced by ligating the bile duct to result in the biliary cirrhosis. Thirty male SD rats were randomly divided into three groups with 10 animals in each one: sham operation group (the bile ducts were isolated and 2 ml NS was injected i.p), HPS model group (the bile ducts were ligated and 2 ml NS was injected i.p) and levofloxacin group (the bile ducts were did as the former group and 20 mg/kg ofloxacin injected i.p). After 6 weeks the portal pressure, ratios of dry weight to wet weight of lung (D/W), weight of spleen, plasma levels of endotoxin, MPO active and MDA contents in the lung. Plasma and lavage fluid of lung were examined. The results of the blood-gas analysis, the bacterial culture of blood, bile and ascites and the evaluation of pathologic change of lung be also investigated.

RESULTSIn levofloxacin group, portal pressure [(19.28 +/- 2.3) compare with (17.80 +/- 2.18)cm H2O, P<0.01], D/W [(5.1 +/- 0.7) compare with (4.9 +/- 0.7), P <0.01], plasma endotoxin levels [(59 +/- 6.2) compare with (268 +/- 35.6)ng/L, P<0.01], MPO active [(0.40 +/- 0.10) compare with (0.24 +/- 0.03)U, P<0.01] and MDA [(0.32 +/- 0.05) compare with (0.22 +/- 0.03) micromol/L, P<0.01] contents in the lung were significantly decreased compared with those in HPS group, and the inflammation of lung was also obviously alleviated.

CONCLUSIONReduction of endotoxin can attenuate the injury of lung in HPS rats.

Hyaluronan acid sodium gels are used in ophthalmic surgery, orthopedic treatment and cosmetic surgery. In 2009,there were 12 domestic manufacturers in China producing 33 kinds of products. 23 kinds of imported products were allowed by SFDA to sale in the meantime. Since manufacturers use different production processes, product performances are quite different. According to the GB/T 16886. 1-2001, we designed a pilot program to evaluate the sodium hyaluronate gel products comprehensively in this paper. The results showed that, except chromosome aberration test of gel A and subchronic systemic toxicity of gel C appeared positive, the remaining samples of the test results were negative. This article provides a reference to write standard of cross-linked hyaluronic sodium gel and the revision of standard YY0308-2004.

Objective　To investigate the prognosis in risk of ventricular arrhythmia in coronary heart disease with heart rate variability (H RV), left ventricular ejection fraction (LVEF) and other clinical background dat a. Methods　A total of 81 patients were divided into ventricular premature beats (VPBs)≥30/h group and VPBs<30/h group. Their LVEF, HRV and cli nical data were studied and analyzed. Results　The age and blood pressure between 2 groups had no significant difference. LVEF, standard deviati on of all normal RR intervals (SDNN), SD of the average of NN interval (SDANN) a nd HRV triangular index (HRVI) were significant less in VPBs≥30/h group than in VPBs<30/h group (43.29±15.38 vs 67.33±11.47，P＜0.01；90.05±22.2 9 vs 117.90±30.32，P＜0.05；77.43±17.78 vs 105.69±28.79，P＜0.05 ；24.54±8.70 vs 32.70±10.87，P＜0.05, respectively). Incidence of myo cardial infarction (MI) was larger in VPBs≥30/h group than VPBs<30/h group. LVE F was the independent predictable factor in risk of ventricular arrhythmia with multinomial regression logistic analysis（B=0.119, P=0.032）. Co nclusion 　Our findings indicate that LVEF is an independent predictable factor i n risk of ventricular arrhythmia in coronary heart disease. Although HRV and MI history can not be used to predict VPB, significant difference is found between 2 groups. High-risk patients could be selected successfully when these data are considered in combination.
