Objective:To evaluate the value of DSA in diagnosis of intestinal vascular malformation.Methods:The clinical and DSA characters in 8 patients with small intestinal malformation were analyzed.There were 6 males and 2 females.All patients were underwent selective and supper selective superior mesenteric inferior mesenteric or colic artery angiographies.Results:The clinical fectures:1)the main sympton is acute lower gastrointestinal bleeding;(2)the results of conventional examination were generally negative;(3)the hemoglobin was dropped down to 4～6 g/ml in a short period.DSA feactures included:(1)artery-vein fistula;(2)markedly stainning in local small intestinal walls;(3)abnormal hyperplasia and distubance of small vessels.Conclusion:DSA is the most valuable method in diognosis of atute intestinal bleeding.

Objective To investigate the effects and mechanisms of extraction centipede extraction (CE) on grafting hepatocellular carcinoma (HCC) in nude mice.Methods We set up model of Bel-7404 cells heterotopic grafting HCC in nude mice,and observed the tumor growth and metastasis after intragastric administration of CE (treatment group).Immunohistochemical methods were used to detect X-chromosome linked inhibitor of apoptosis protein(XIAP),bax gene,vascular endothelial growth factor(VEGF) and angiopoietin-2(Ang-2) in tumor tissue.Results There was distinctive inhibitive effect of CE on in Bel-7404 cells heterotopic grafting HCC in nude mice.The staining cells population,staining intensity and the optical density(OD)of XIAP,VEGF and Ang-2 in the control group were higher than those in treatment group,but those of BAX were lower than that in treatment group,and there was significant difference between the 2 groups(P

0.05). S.sobrinus strains had significantly lower initial adhesive ability to saliva coated hydroxyapatite in the absence of sucrose than S.mutans (P

砄bjective:To investigate the consistency of Streptococcus mutans and Streptococcus sobrinus isolates identified by colony morphology,biochemical tests and DNA base content analysis.Methods:46 clinical isolates (30 of S.mutans and 16 of S.sobrinus ) were identified by colony morphology,biochemical tests and determination of DNA base contents with reversed phase high performance liquid chromatography. S.mutans Ingbritt and S.sobrinus 6715 were used as the controls. Results:The DNA contents (G+C mol%) of S.mutans and S.sobrinus clinical isolates, identified by colony morphdogy and biochemical test, were 37.52 and 45.19 respectively,consistent with the expected 36～38 and 44～46 mol percent of G+C.Conclusion: S.mutans and S.sobrinus isolates,identified by colony morphology and biochemical tests ,were consistent with the DNA G+C content analysis. S.mutans and S.sobrinus can be easily and reliably identified by colony morphology and biochemical tests.

Baicalein is an important component of traditional Chinese herb, Scutellariae Radix(Huang Qin), and has various efficacies, including anti bacterial, antivirus, anti inflammation, protecting the liver function, diuresis, anti tumor, and shows good values in clinical application. It was majorly applied to acute or chronic inflammation. This article reviews developments in its pharmacological action and mechanism and provides theoretical evidences for exploiting of baicalein.

Objective To study the effects of single leaf Asarum on pulmonary ventilation in experimental rats with syndrome of cold fluid shooting lung. Methods Wistar rats were randomly divided into three groups including singe leaf Asarum group [fed with water extracts of singe leaf Asarum 1 mL/(kg?d)], singe leaf Asarumi Miq group [fed with water extracts of singe leaf Asarumi Miq 1 mL/(kg?d)] and normal saline group [fed with 0.9% normal saline 1 mL/(kg?d)]. After fed continually for 6 days, whole lung of rats were washed with normal saline [7 ℃, 2.5 mL/(kg?d)] and then were perfused for 30 seconds. This treatment was repeated 5 times every 5 minutes to make the model of cold fluid shooting lung. The fluid of perfusion was collected and detected. The changes of TXB2, ET, protein and phospholipids of the fluid were measured before and after lavage. Results TXB2, ET and protein in the perfusing fluid ascended obviously, while phospholipids were low in normal saline group. TXB2 and ET in singe leaf Asarum group and single leaf Asarumi Miq group were less than that in normal saline group (P

Objective To study the apoptosis in human gastric cancer cell BGC-823 induced by the components in serum of Banxia Xiexin prescription and different herbal fomulation. Method multiplication of cell BGC-823 was observed with MTT method. The genic expression of bcl-2 was tested by S-P immunohistochemistry tehnique. Results As for inhibition of cell BGC-823 multiplication, the groups of Xinkai, Kujiang and Xinku in Banxia Xiexin prescription and different herbal fomulation was dose-dependent and more sensitive than the groups of Xingan, Kugan, Ganbu and the intact prescription (P

Objective To study effect of the components in serum of Banxia Xiexin Prescription and different herbal formula on the apoptosis of cell BGC-823 and apoptosis-related gene expression. Methods The genic expression of bcl-2 and bax was tested by S-P immunohistochemistry technique. Results The apoptotic index of the groups of Xinku in Banxia Xiexin Prescription was significantly higer than that in the groups of Xingan, Kugan, Ganbu and the intact prescription (P

OBJECTIVE:To provide reference for rational clinical use of drugs and sound management thereof. METH-ODS:The relative data of antihypertensive drugs applied in 34 hospitals in Wuhan city during 2011 and 2013 were analyzed sta-tistically by using the analytical method of the Defined Daily Dose(DDD)recommended by WHO. RESULTS:Both consump-tion amount and DDDs of antihypertensive drugs in Wuhan city were increasing during 2011 and 2013,where calcium-channel blockers(CCB)enjoyed the largest consumption amount and the highest DDDs,with the constituent ratio of over 40% respec-tively,followed by angiotensinⅡreceptor antagonist (ARB) and angiotensin converting enzyme inhibitors (ACEIs). The con-sumption amount and DDDs of new compound preparation also increased. Top three single drugs in terms of consumption amount were amlodipine,levamlodipine and valsartan,while amlodipine,nifedipine and felodipine ranked the top three in DDDs list. CONCLUSIONS:Wide usage of antihypertensive drugs in Wuhan City are respectively CCB,ARB,ACEI,adrener-gic receptor blockers and diuretics,which are applied in current principle of antihypertensive drugs use and basically rational in clinical application.

Calculus Bovis (CB) is one of the precious traditional Chinese medicines (TCM) and has been widely used in oriental countries over 2000 years.It possesses a broad spectrum of pharmacological properties such as relieving fever,analgesic,diminishing inflammation,sedation,reducing blood pressure,recovering gallbladder functions,antioxygenation,and anti-tumor and improving immunity,et al.Due to the scarce resource and high price of natural CB,its substitutes,artificially synthesized CB and C.Bovis Sativus (CBS),also called in vitro cultured C.Bovis,have already been developed and widely used in medicine preparation.By using the literature material method,the current article explored literatures regard to pharmacological activities and clinical application of CB and its substitute,and the compound preparations were also included,from 1949 to 2016 in journals of domestic and foreign.All documents are summarized to provide a valuable reference for further basic or clinical research about CB and its substitute.
