Objective To investigate the effect of Scutellaria baicalensis stem-leaf total flavonoids(SSTF) on blood glucose,blood lipid levels and insulin resistance in type 2 diabetic rats with hyperlipidemia,and to explore the possible therapeutic mechanism. Methods Experimental rat model was established by feeding high-fat diet and intraperitoneal injection of small-dose streptozotocin. The effects of SSTF on blood glucose,blood lipid,insulin sensitive index(ISI) and antioxidative capacity of experimental rat model were investigated. Results SSTF significantly reduced the serum fasting blood glucose(FBG),total cholesterol(TC),and low-density lipoprotein cholesterol(LDL-C) levels,increased high-density lipoprotein cholesterol(HDL-C) level and ISI,and reduced triglyceride(TG) level to some extent. SSTF also had an effect on decreasing malondialdehyde(MDA) content in both serum and liver tissue,increasing serum superoxide dismutase(SOD) activity significantly and glutathione(GSH) content to some extent. Conclusion SSTF have significant effect on decreasing blood glucose and blood lipid and improving insulin resistance in type 2 diabetic rats with hyperlipidemia. Its therapeutic mechanism may be related to the antioxidation function.

Objective To investigate the effect of Scutellaria baicalensis stem-leaf total flavonoids(SSTF)on lipid metabolism in hyperlipidemia rats.Methods On the basis of establishing hyperlipidemia rat model,blood and liver lipids,lipid metabolic enzyme,and the amount of fecal bile acids were investigated after feeding of fatty emulsion for 30 days.Results Compared to the model group,SSTF significantly reduced the serum levels of total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterol(LDL-C),and increased high density lipoprotein cholesterol(HDL-C),increased the activity of lecithin cholesterol acyltransferase(LCAT).SSTF also showed the effect on decreasing liver TC,TG and increasing the amount of fecal bile acids.Conclusion SSTF have an effect on decreasing lipid metabolism in hyperlipidemia rats,and the possible mechanism is associated to the increase of LCAT activity and fecal bile acids excretion.

AIM: To investigate the protective effects of the total paeony glycoside(TPG) on the focal cerebral ischemia and regional cerebral blood flow(rCBF) in rats. METHOD: The rat model of focal cerebral ischemia was made by middle cerebral artery occlusion(MCAO) with nylon suture.TPG was injected into every group rats once a day before 48 h,and injected before MCAO 30 min and after 4 h,12 h.After 24 h the effects of the drug were studied about neurological deficit,the water content of brain tissue,the cerebral infarcted zone,under microscopic examination,as well as rCBF on each rat with laser Doppler fiowmeter(LDF). RESULTS: The sympton of brain ischemia was obvious in model rats by contrast to the sham rats,and the model rats rCBF decreased markedly after MCAO.50 mg/kg and 100 mg/kg TPG injection could obviously promote neurological deficit,decrease the water content of brain tissue and the cerebral infarcted zone.And the pathological slices also proved its protective effect on neuron.The laser Doppler flowmeter detected result indicated that 100 mg/kg TPG inject could greatly increase MCAO rats rCBF. CONCLUSIONS: TPG injection has a marked prospective activity on rat focal brain ischemia in rats,and the increase of rCBF may be one of the protection mechanism.

Objective:To evaluate the cough-settling, phlegm-dispelling and panting-calming actions of Ginkgo Distillate. Methods: The cough-settling and phlegm-dispelling effects were observed on the ammonia water-induced cough model of mice and phenol red expectoration method. The panting-calming effect was observed by wheezing and panting incubation period and relaxation test of isolated tracheal smooth muscle. Results: Ginkgo Distillate could inhibit mouse cough induced by ammonia water, promote mouse tracheal expectoration induced by phenol red, remit the wheezing and panting induced by histamine phosphate, prolong the wheezing and panting incubation period. It also possessed the inhibition on guinea pig tracheal contraction induced by histamine phosphate. Conclusions: Ginkgo Distillate has the cough-settling, phlegm-dispelling and panting-calming actions.

A cold saponification method for determination of 5 lutein stereoisomers in dairy products by high performance liquid chromatography ( HPLC ) was developed. Samples were cold-saponified at room temperature and extracted by n-hexane/petroleum/dichloromethane ( 2: 2: 1 , V/V/V ) . Then 5 lutein stereoisomers were separated on a YMC C30 column with gradient elution using methanol/methyl tert-butyl ether as the mobile phase, and data were acquired by a photodiode array detector at wavelength of 445 nm. The calibration curve was linear in the range of 0 . 127-5 . 082 mg/L with correlation coefficient of 0 . 9999 , and the recoveries were from 96 . 7% to 102 . 2% with the RSDs in the range of 4 . 1%-5 . 4% ( n=6 ) . The limit of detection was 0 . 010 μg/g ( S/N=3 ) , and the limit of quantification was 0 . 030 μg/g ( S/N=10 ) . By presenting results of good accuracy, precision and sensitivity, this method validates its suitability for routine analysis of 5 lutein stereoisomers in dairy products.

Objective To study the relation of esophageal motility and acid reflux between gastroesophageal reflux disease (GERD) patients with and without esophageal injury.Methods A total of 25 patients who met the GERD diagnosis criteria were conducted esophageal-gastric-duodenal endoscopy examination and followed with high-resolution esophageal manometry.The changes of esophageal pH postprandial were also detected.The differences of esophageal motility and acid reflux time between GERD patients with and without esophageal injury were compared.Patients were divided into non-acid reflux group and acid reflux group according to DeMeester score.The changes of esophageal motility indexes of these two groups were compared.Wilcoxon test and t test were used for statistical analysis.Results There was no significant difference in baseline value of lower esophageal sphincter (LES) pressure,remained LES pressure,speed of the esophageal peristalsis,the time of esophageal pH<4 and DeMeester score between groups with and without esophageal injury (all P>0.05).But esophageal contraction amplitude of group with esophageal injury was lower than that of group without esophageal injury (31.9 mm Hg vs 64.2 mm Hg,1 mm Hg=0.133 kPa,Z=-2.37,P=0.02).There was no significant difference in baseline value of LES pressure,remained LES pressure,speed of the esophageal peristalsis between acid reflux group and non acid reflux group (all P>0.05).But the esophageal contraction amplitude of acid reflux group was lower than that of non acid reflux group (36.4 mm Hg vs 71.8 mm Hg,Z=-2.25,P=0.02).Conclusions There was no significant correlation between the LES pressure and esophageal acid reflux with esophageal injury in GERD patients.Esophageal peristalic contraction may be associated with esophageal injury and acid reflux.

OBJECTIVETo determine the effects and related mechanism of Scutellaria baicalensis stem-leaf total flavonoid (SSTF) on vascular smooth muscle cells (VSMCs) proliferation induced by high triglyceride blood serum (HTG).
METHODVSMCs isolated from rat aorta were cultured in vitro and proliferation was stimulated by HTG, SSTF was added to influence the proliferation of VSMCs. The proliferation and cell cycle of VSMCs were determined by MTT assay and flow cytometry, respectively. CO released into the culture media was quantitated by measuring carbon monoxide hemoglobin (COHb). The protein expressions of HO-1 and extracellular signal-regulated kinase (ERK/p-ERK) were detected by Western blot analysis.
RESULT500 mg x L(-1) SSTF could obviously suppress the cell multiplication by HTG's induction, remarkably increase the production of COHb in VSMCs, obviously suppresse the mitotic cycle progress of VSMCs (P < 0.05, P < 0.01), in the time and dosage dependence. Furthermore, 500 mg x L(-1) SSTF remarkably declined the ERK/p-ERK protein expression (P < 0.01), but did not have the influence on the HO-1 protein's expression.
CONCLUSIONSSTF inhibited the proliferation of VSMCs directly by blocking cell cycle progression, and the ERK signal transduction way possibly participated in the cytoprotection of SSTF.
