Objective:To study on effects of Welling Granule on union of peptic ulcer and the gastrical ulcer induced by acetic acid in the rat. Methods:With random grouping method,the clinical recurrence rate of peptic ulcer,and regenerated macosa of healing gastric ulcer in the rat was investigated quantitatively with hematoxylin-eosin staining,and gastric wall combining macus amount,gastric acid and pepsin activity were determined.Results:Weiling Granule could decrease the recurrence rate of peptic ulcer,improve injury of the tissue of gastric macosa in the rat,increase gastric wall combining mucus amount,and decrease secretion of gastric acid.Conclusion:Weiling Granule can increase quality of ulcerative healing,which is possibly one of the mechanisms of anti- recurrence of peptic ulcer clinically.

To study the changes in levels of tumor necrosis factor ? (TNF ?), interleukin 6 (IL 6) and interleukin 1? (IL 1?) produced by the peripheral blood mononuclear cells (PBMC) of patients with congestive heart failure (CHF), and to investigate the effects of captopril, one of angiotensin converting enzyme inhibitors in active form, on production of these cytokines. PBMC from 35 CHF patients and 12 healthy controls were isolated by density centrifugation with Ficoll Hypaque, and were cultured with captopril at 10 -4 ～10 -2 mol/L in the presence of lipopolysaccharide (LPS). After incubation for 24 hours, TNF ? and IL 6 contents in the culture supernatants were measured by an enzyme linked immunosorbent assay (ELISA), and IL 1? by radioimmunoassay (RIA). The results showed that PBMC from CHF patients released significantly more TNF ?, IL 6 and IL 1? compared with cells from controls ( P

Objective To observe the pharmacological characteristics of a novel antihypertensive drug iptakalim hydrochloride (Ipt) by dilating large and small arteries. Methods The vasodilating action of Ipt was studied using isolated rat tail artery helical strips and aortic rings. Results The vasodilating action of Ipt at 10 7-10 3mol/L was observed in rat tail artery strips precontracted with potassium chloride (KCl) in a concentration and endothelium dependent manner, but no significant vasodilating effect was seen on rat aortic rings. Ipt-induced relaxation in tail artery was significantly greater in spontaneous hypertensive rats than that in normotensive rats. The vasodilating actions of Ipt in small arteries could be markedly antagonized by glibenclamide, an inhibitor of ATP-sensitive potassium channels. Conclusion The results suggest that iptakalim hydrochloride has a selective vasodilating action in small arteries, and the action is related to activation of ATP-sensitive potassium channels.

Objective To investigate the effect of hydrogen sulfide (H2S) on the cholesterol efflux and ATP-binding cassette transporter A1 (ABCA1) expression in foam cells .Methods RAW 264 .7 macrophages were incubated with oxidized low density lipoprotein to induce foam cells .Foam cells were incubated with H2S donor sodium hydrosulfide .Cholesterol efflux from macropha-ges was tested by labed cholesterol .The cellular levels of free cholesterol (FC) ,cholesterol ester (CE) and total cholesterol (TC) were measured by high performance liquid chromatography assays .The mRNA and protein expressions of ABCA1 were detected by Real-time PCR and Western blot .Results Compared with the foam cells ,the rates of cholesterol efflux were significantly in-creased ,the levels of TC ,FC ,CE and CE/TC ratio were significantly decreased(P<0 .05) and expression of ABCA1 was signifi-cantly increased by treatment with H2S in dose-and time-dependent manner(P<0 .05) .Conclusion H2S up-regulates of expres-sion ABCA1 and promotes cholesterol efflux in RAW 264 .7 macrophage-derived foam cells .

ObjectiveTo observe the clinical efficacy of acupuncture at cranial sutures (cranial acupuncture) plus rehabilitation training in treating cerebral infarction.MethodSixty patients with cerebral infarction were randomized into an acupuncture-rehabilitation group (cranial acupuncture plus rehabilitation training) and a rehabilitation group (dryrehabilitation training), 30 cases in each group, to respectively receive cranial acupuncture plus rehabilitation training and dry rehabilitation training. The Fugl-Meyer Assessment (FMA) and Barthel Index (BI) were adopted to respectively evaluate the motor function of limbs and activities of daily living (ADL); the content of hypersensitive C-reactive protein (hs-CRP) was also observed before and after treatment for the evaluation of therapeutic efficacy.ResultThe acupuncture-rehabilitation group wassuperior to the rehabilitation group in improving the motor function and ADL, and down-regulating the hs-CRP content (P<0.05).ConclusionCranial acupuncture plus rehabilitation training is the optimal protocol in treating cerebral infarction, and it canproduce a more significant efficacy than dry rehabilitation training.

OBJECTIVEWolff-Parkinson-White syndrome (WPW) is considered to be an autosomal dominant hereditary disease, but the gene is not identified. The objective of this study was to localize the genetic loci of Wolff-Parkinson-White syndrome.

METHODSLinkage analysis between the disease of Wolff-Parkinson-White syndrome and 3 STR (short tandem repeats) markers on 7q3 (D7S505, D7S688, and D7S483) was tested in 3 kindreds of the Wolff-Parkinson-White syndrome (101 numbers in total) by genotyping.

RESULTSWolff-Parkinson-White syndrome was linked to the loci above. The maximum two-point Lod score detected at D7S505 was 6.4 at a recombination fraction (theta) of 0.1; the Lod score of D7S688, D7S483 was 5.3 vs 2.5.

CONCLUSIONThe gene of Wolff-Parkinson-White syndrome is located at 7q3.

Objective To analyze the clinic features and hereditary characteristics of three subtypes of porokeratosis, namely disseminated superficial actinic porokeratosis (DSAP), porokeratosis palmaris et plantaris disseminata(PPPD) and porokeratosis of Mibelli (PM) in five pedigrees with porokeratosis. Meth-ods After clinical and pathological diagnosis, every living family member of the five pedigrees with poro-kerotosis was undergoing medical examination and genetics analysis. These five pedigrees consisted of three DSAP pedigrees (totally 266 family members including 100 patients), and one PPPD pedigree (composing of 90 members including 26 patients), one PM pedigree (cornposing of 34 members including 17 patients). Results While diagnosed as porokeratosis, the five pedigrees included three distinctive variants, each with its own clinic characteristics. The lesions was initiated on the face in DSAP subtype, on palms and the flex-ion side of fingers in PPPD subtype; or involving sun-covered areas in PM subtype. Of the three subtypes of porokeratosis, the onset age in DSAP subtype was earliest, usually about 8-20 years old, about 14-20 years old in PPPD subtype, but PM subtype about 20-30 years old. Conclusions As a group of autosomal dominant genodermatosis, porokeratosis presented various clinic variants with different genetic basis. And, different subtype could be seen in a same patient or same pedigree.
