Objective To study the changes in the endothelial reserve capacity to release tissue plasminogen activator (tPA) and nitric oxide (NO) and its relation to vasodilation and to diabetic angiopathy. Methods The capacity of vascular endothelium to release tPA and NO was examined by venous occlusion of the upper arm. Brachial artery diameter was measured at baseline, during postocclusion reactive hyperemia (flow-mediated endothelium-dependent), and after sublingual nitroglycerol administration (endothelium-independent), using a high resolution ultrasound technique in 15 control subjects and 23 patients with type 2 diabetes mellitus. Vasodilation was expressed as the percentage change relative to the baseline diameter, while endothelial tPA and NO release was expressed as the percentage change relative to the baseline tPA and NO levels. Thickness of the intima of carotid artery was measured using ultrasound imaging. Results There was no significant difference in endothelium-independent vasodilation between control subjects and diabetics. However, significant reductions in endothelium-dependent vasodilation (P

Mixed saponin molecules in the extraction of Panax notoginseng(PNE) can be effectively desorpted into the molecular ionization for measurement and analysis by mass analyzer from matrix assisted laser desorption ionization-time of flight-mass spectrometry(MALDI-TOF MS). The saponin samples with chromatography purity were directly analyzed by MALDI-TOF MS, which indicated that the sensitivity of the method was higher than that of RP-HPLC. A technology of MALDI-TOF MS was directly employed to analyze the saponin kinds and their relative contents in Panax notoginseng(PN) while the saponins were perfectly extracted from the Chinese traditional medicine of PN. It was indicated that there were at least 20 saponins consisting of different molecular structure and that the content of both ginsenoside Rg1 and notoginsenoside R1 in PNE was relative high. R1 saponin was extracted and identified to follow its metabolism pathway by both thin layer chromatography and MALDI-TOF MS, respectively. The saponin fingerprinting maps in PNE can be established to evaluate the quality of PE and to study both metabolism pathway and mechanism of extra minim saponins in vivo.

Objective To investigate whether nimodipine could reduce complications after microvascular decompression in patients with hemifacial spasm. Methods 220 patients with hemifacial spasm , admitted into our hospital from May 2011 to Oct. 2013 , were all treated by microvascular decompression. They were divided randomly into two groups. Patients in the treatment group were treated with nimotop 50 mg/d after the operation for the first 3 days, then was orally taken 30 mg/d for a week. Patients in the control group were treated with the same after the operation without nimodipine. The postoperative complications including hearing deficit and peripheral facial paralysis were closely observed within three months after operation. Results The total effective rate was 100% in both groups. The incidence rate of peripheral facial paralysis and hearing deficit in treatment group was significant lower than that of the control group (P < 0.05). Conclusion Nimodipine has significant effect on reducing the incidence rate of peripheral facial paralysis and hearing deficit after microvascular decompression in patients with hemifacial spasm.
