Objective To comprehend the action mechanism of simvastatin in pulmonary hypertension(PH)when it induced by high pulmonary blood flow.Methods Abdominal aorta-inferior vena cava shunting was made in rats to establish animal model of PH induced by high pulmonary blood flow,simvastatin with dose of 2 mg/(kg?d)was used to interfere for 11 weeks.And then,pulmonary arterial pressure,apoptosis rate and proliferation rate of pulmonary vascular smooth muscle cell were determined.Results were compared with other groups.Results Simvastatin could cut down the pulmonary arterial pressure well,pulmonary arterial pressures of simvastatin group rats were lower than those of spliting groups obviously(Pa

To clarify the effects of zinc on the proliferation and apoptosis of cultured human retinal pigment epithelia (RPE) and the expression of caspase-3 in RPE cells. The effect of Zinc on the proliferation of RPE were examined with MTT method. TUNEL method was used to detect the apoptosis of RPE cells. Caspase-3 was detected by immunohistochemistry. A concentration of zinc higher than 0.001 microM could inhibit the proliferation of RPE. And the relationship between concentration of zinc higher than 10 microM and growth prohibition rate of RPE cells was dose-dependent. All concentrations of zinc including 0.001 microM enhanced the expression of caspase-3 of RPE. But only the concentration of zinc higher than 0.01 microM could induce apoptosis of RPE. It is concluded that zinc could enhance the expression of caspase-3 of RPE cells and induce apoptosis of RPE cells. Caution should be taken when using zinc supplements for the treatment of ARMD patients without deficiency of zinc.

Objective To explore the role of the preoperative DSA examination and selected embolization in surgical treatment of intracranial huge meningiomas .Methods The clinical materials of 13 patients was collected and analyzed .Preoperative DSA was carried out in all cases ,10 of 13 underwent selected preoperative embolization ,the meningiomas were totally excised by surgery 4 to 7 days after the embolization .Results After the embolization ,DSA showed that the blood fed to the tumors was completely blocked in 8 cases ,and in great part in 2 cases .All tumors were totally removed ,the bleeding during operation was significantly decreased in patients who underwent preoperative embolization compared to the patients without embolization (P<0 .05) .Necrosis in different degree of meningiomas was found in postoperative pathological examination .There were no severe complications occurred during and after operations in all patients .Conclusion Preoperative selective embolization could significantly decrease the bleeding during operations .

This article systematically summarizes the non-clinical safety studies, pharmacological studies and postmarketing safety studies of Xiyanping injection based on literature. These studies include acute toxicity test, long-term toxicity test, reproductive toxicity test, active and passive anaphylaxis test, curative mechanism study, clinical trials of effectiveness, active surveillance, security analysis of passive monitoring data, the real world analysis of hospital information system (HIS) data, literature analysis, etcetera This article also analysis the relationship of the different evidence, summarizes the strategy of the researches, in order to make it to be a reference for making a systemic research program of traditional Chinese medicine injection.

The contents of coumarins in the sulfur fumigated Angelicae Dahuricae Radix (Baizhi, ADR) were reduced significantly. To achieve the quality control of ADR, the qualitative identification of sulfur fumigated ADR and quantitative model of imperatorin content should be established. The near-infrared (NIR) spectrograms of non-sulfur and sulfur fumigated ADR were collected by NIR diffuse reflectance spectroscopy technology and pretreated by the method of first derivative derivation and vector normalization. The Ward's Algorithm method was used for the cluster analysis. The non-sulfur and sulfur fumigated ADR can be quickly identified in the range of 8,806. 0-3 811.0 cm(-1) based on the cluster analysis. The NIR quantitative model of imperatorin was established by the contents of imperatorin determined by HPLC in combination with partial least squares regression analysis. According to the calibration model established in this study, correlation coefficients (R2), the root-mean-square error of cross-validation (RMSECV), and the root-mean-square error of prediction (RMSEP) for imperatorin were 0.982 8, 0.006 8, 0.011 8, respectively. The quantitative model of imperatorin can be applied to determine the content of imperatorin in ADR accurately.
