AIM: To investigate the chemical constituents of the plant drug Cornus officinalis Sieb et Zucc. which is widely used in Chinese traditional medicine, having actions of invigorating the liver and kidney, strengthening the body, and of an astringent, etc. METHODS: A sedoheptulose gallate was isolated from the water extracts of fruits of C.officinalis using various chromatographies. The structure determination was based on spectral (UV, IR, 1H & 13CNMR and MS) and chemical evidence. RESULTS: Its structure was characterized to be 7-O-galloyl-D-sedoheptulose (I). The proportion of its three major conformation forms of β-F, α-F and α-P in aqueous solution was estimated to be 57:24:19 according to their C-1 peak heights in the 13CNMR spectrum. CONCLUSION: I was found in natural world for the first time and its β-D-heptufuranosyl form was the predominant existing tautomer in its equilibrated aqueous solution according to NMR determination.

To explore the relationship between serum resistin concentration, hypertension, degree of obesity and blood glucose, fasting serum resistin concentration was measured with EIA in 17 normotensives and 44 patients with essential hypertension. Serum resistin concentration was significantly correlated with age and body fat percectage (BF%). The concentration level was significantly higher in grade 2 hypertension group [(30.5?11.0)?g/L] than in grade 1 hypertension group [(24.3?10.5)?g/L] and in normotensives group [(21.5?6.1)?g/L]. The difference in serum resistin concentration between the three groups disappeared when age and BF% were corrected by analysis of covariance. Serum resistin concentration was significantly correlated with systolic blood pressure, age, BF%, fasting plasma glucose. A stepwise multiple linear regression analysis revealed that age, BF% and fasting plasma glucose were significantly independent predictors of serum resistin concentration. The results suggest that serum resistin concentration is not directly related to blood pressure, but the concentration level is actually correlated with age, BF% and glucose metabolism.

Objective To investigate the effect of obesity on change of the levels of blood glucose and blood lipid after treatment with different combinations of antihypertensive drugs in patients with essential hypertension (EH). Methods One hundred and thirty-eight patients with mild to moderate EH were randomly divided into 3 groups with different combinations of drugs: reserpine with dihydralazine, hydrochlorothiazide, potassium chloride group (group 1), fosinopril with indapamide group (group 2), and nifedipine with atenolol group (group 3). Treatment period lasted for 14 months. Every group was divided into obesity subgroup and non-obesity subgroup according to Chinese obesity standard. Results After treatment, blood glucose levels were significantly decreased and blood lipid level was unchanged in both obesity subgroup and non-obesity subgroup of group 1. High density lipoprotein-cholesterol (HDL-C)/low density lipoprotein-cholesterol (LDL-C) ratio was significantly decreased and blood glucose was significantly increased in obesity subgroup, however, there was not significant change in the level of blood glucose and blood lipid in non-obesity subgroup of group 2. Blood glucose level was significantly increased and HDL-C/LDL-C ratio was significantly decreased in obesity subgroup, however, there was significant increase only in fasting blood glucose in non-obesity subgroup of group 3. Conclusions The results suggested that treatment with a combination of reserpine and dihydralazine, hydrochlorothiazide, potassium chloride showed beneficial effect on improving carbohydrate metabolism in both obese and non-obese patients with EH, while the treatment with the combination of fosinopril with indapamide deteriorated carbohydrate and lipid metabolism in obese patients with EH, and the treatment with combination of nifedipine with atenolol impaired carbohydrate and lipid metabolism in obese patients with EH.

Objective To investigate the effects of total alkaloids in Buxus microphylla leaves (ABML) on isolated rats thoracic aorta rings,and then to explore the possible mechanisms underlying the effects.MethodsThoracic aortas of Wistar rats were isolated,removed,and mounted onto an organ bath.The effects of ABML at different concentration on the contraction of isolated thoracic aorta rings (with and without endothelium) precontracted with KC1 or PE were observed with organ bath technique.Dose-effect curves of CaCl2 were recorded by organ bath technique.The concentration of intracellular Ca2+ ([Ca2+]i) increased by PE,KCI,and caffeine in the presence of ABML was determined using Ca2+ sensitive fluorescence indicator Fura-2/AM loaded thoracic aorta vascular smooth muscle (VSM) cells of rats.ResultsIn aorta rings precontracted with PE and KCI,ABML produced concentrationdependent relaxation in both intact and denuded endothelium ring groups.There was no difference in the inhibition of contraction between the intact and denuded endothelium ring groups at the same concentration.Exposure of isolated thoracic aorta rings to ABML led to a significant reduction in the contracting response induced by CaCI2,and shifted the cumulative concentration-response curves to right.ABML could significantly inhibit the extracellular Ca2+ influx induced by PE and KCI under [Ca2+]0 of 1.5 mmol/L,with inhibitory ratios of 40.2％ and 49.9％,respectively.In the case of Ca2+-free,ABML could significantly inhibit the intracellular Ca2+ release induced by PE,with inhibitory ratio of 72.4％.ConclusionABML relaxes thoracic aorta VSM cells by suppressing influx of extracellular Ca2+ via voltage-dependent Ca2+ channel and receptor-operated Ca2+ channel.

Atrial fibrillation (AF) is a common kind of arrhythmia,it is one of the main reasons causing ischemic stroke in aged patients.Left atrial appendage is the primary site where the thrombus is formed in non-valvular atrial fibrillation (NVAF) patients.Recent researches have indicated that occlusion of left atrial appendage can effectively reduce the occurrence of ischemic stroke in NVAF patients,its curative effect is no less than the preventive treatment effect of warfarin.The use of an ideal left atrial appendage occluder is the key to ensure a successful occlusion of the left atrial appendage.After decades of research,several left atrial appendage occluders have been developed,among them Watchman occluder and Amplatzer cardiac plug (ACP) are commonly used nowadays in clinical practice,and some kinds of occluder are still at their experimental research stage.This article aims to make a brief introduction about the current status of the study and the clinical application of left atrial appendage occluder.(J Intervent Radiol,2017,26:281-284)

Objective: To investigate the effect of human vascular endothelial growth factor on restenosis after angioplasty. Methods: A rabbit model of injured carotid artery was established using percutaneous transluminal angioplasty. The pcDNA3/hVEGF165（500 μg,n=12） and pcDNA3 （500 μg,n=12） were separately transfected into injured arterial wall with 30 min incubation. The carotid artery was imaged by arotic angiography at the end of week 2 and week 4. Pathology analysis and Northern blot analysis were performed for harvested injured artery segment. Results: Arotic angiography showed carotid artery diameter narrowness were obviously lessened at week 2 and week 4 in experimental group than that in control group; H-E stains showed lumina narrow ratio were obviously reduced at week 2 and week 4 in experimental group than that in control group［（9.58±1.35）% vs (31.72±1.72)%；(18.09±2.93)% vs (44.05±3.28)%， P<0.01 ］; By Northern blot analysis, the expression of hVEGF165mRNA in experimental group were upregulated than in contol group. Conclusion: pcDNA3/hVEGF165 can be transfected into smooth muscle cell and continue to secret bioactivity protein at least for 4 weeks; it can accelerate reendothelialization and prevent restenosis.

Objective: This multi-group case control study was performed to determine whether Helicobacter pylori infection was associated with gastric cancer and stomach diseases. Methods: Gastric cancer and stomach disease patients that were diagnosed pathologically between 1994 and 1996 years were divided into several case groups and control group, all histological specimens collected in gastric cancer high risk region of Shandong Province were used to measure exposure history. Results: After variables concerning age, sex and education were adjusted, odds ratios of chronic superficial gastritis in antrum, peptic ulcer disease and active degree of inflammation associated with H. pylori infection remained significant (OR was 2.072, 2.980, 2.086 respectively). Correlation analyses showed negative relationship between degree of stomach diseases and H. pylori infection(r=－0.217). Conclusion: The results support the hypothesis of a relationship between H. pylori infection and the development of chronic superficial gastritis in antrum, peptic ulcer disease and active degree of inflammation.
