Objective To establish a HPLC method for determining and comparing the contents of diosbulbin B in
Dioscorea bulbifera L. from different regions. Methods The medicine powders were extracted twice by water, then the water extracts were combined and detected by HPLC at 35℃,with Kromasil-C18 column (4. 6 mm×250 mm,5μm) and a mobile phase of acetonitrile-water-glacial-acetic acid (34660. 1). The flow rate was 1. 0 mL·min-1 and the detection wavelength was 210 nm. Results The linear range of diosbulbin B was 26. 0-260. 0 μg·mL-1(r=0. 999 9). The average content of diosbulbin B in Dioscorea bulbifera L. from different areas was that of Hebei>Guangxi>Jiangsu>Sichuan>Zhejiang. Conclusion The method is simple,quick,accurate and suitable for the determination of diosbulbin B in Dioscorea bulbifera L. from different regions.
2.Xinnaoxuemianning Combined with Statins on Carotid Atherosclerotic Plaque in Patients with Cerebral Infarction
Chinese Journal of Biochemical Pharmaceutics 2017;37(9):65-66,69
Objective To investigate the effects of Xinnaoxuemianning combined with statins on carotid atherosclerotic plaque in patients with cerebral infarction. Methods 180 cerebral infarction patients were divided into the observation group (90cases) and the control group (90cases) by random number table method. The control group was given atorvastatin calcium tablets and the observation group was given additionally Xinnaoxuemianning. The changes and prognosis of carotid atherosclerotic plaques were evaluated before and after treatment, and the incidence of adverse reactions was counted. Results There were no differences in the carotid atherosclerotic plaque, TCM syndrome score and neurological deficit severity between the two groups before treatment. After treatment, the above indexes were significantly improved, and the increasing degree of the observation group was better than that of the control group. The incidence rate of adverse reactions was lower in the observation group than that in the control group (5.56% vs.13.33%) (P<0.05). Conclusion Xinnaoxuemianning can reduce the carotid atherosclerotic plaque area and correct the unstable plaques in patients with cerebral infarction.

Objective To understand the current status of health knowledge demands and its associated factors in general population. Methods A questionnaire-based survey by convenience sampling method was carried out in 700 subjects aged over 15 years old in October 2014. Information of demographics and health knowledge demands were collected. Data was analyzed using SPSS 17.0. Results A total of 653 subjects were responded, with a response rate of 93.3%. Respondents in male and female were 339 (51.9%) and 314 (48.1%) respectively. There were no differences among age , educational levels and self-reported health status between the two genders 86.6% of the participants showed that they had interests in health knowledge. Educational level and age were the factors associated with the interests. 65.8% and 72.3% of people want to get practical health knowledge of western and traditional Chinese medicine respectively. The top concern of health issues were cardiovascular and cerebrovascular diseases. For preferred ways of learning health knowledge , television is the favorite one (44%), especially in elderly (over 63.8%). A relative high option rate was newspaper and magazine in all age groups. However, young people showed that they preferred the ways of the internet and Wechat (about 50%). For health disseminators, the participants in all age had greatest trust in experts in large hospitals (over 60%). The second option was retired old experts. The experienced patients were convinced in some degree and increased with age. Conclusions In future, health education in general population should considered the characteristics of the population and the applicability of knowledge. Besides , it is necessary to integrate traditional Chinese medicine with Western medicine, traditional media with new media, also authoritative experts and living example.

Objective:To construct a THANK adenovirus vector and observe expression of THANK in SMMC-7721 cell line after THANK adenovirus infection. Methods: Human THANK cDNA was cloned into shuttle vector pAdTrack-CMV, and the resultant plasmid was linearized and subsequently cotransformed into E.coli BJ5183 with an adenoviral backbone plasmid pAdEasy-1.Recombinants were then selected and the linearized recombinant plasmid was transfected into 293 cell lines. Finally, THANK recombinant adenovirus production was observed by fluorescent microscope and confirmed by PCR and Western blot analysis. Further THANK adenovirus were used to infect SMMC-7721 cells with different MOI. The expression of THANK in SMMC-7721 cells was observed by fluorescent microscope and by PCR and Western blot analysis. Results: A human THANK recombinant adenovirus vector was constructed and infected SMMC-7721 cell line with high efficiency. The expression of THANK in SMMC-7721 cells was over 35 ng/ml 5 d after transfection. Conclusion: Adenovirus can induce stable expression of THANK in SMMC-7721 cells.

Objective To determine the pattern and incidence of congenital coronary anomalies (CCA) in adults undergoing coronary angiography. Methods The diagnostic angiographic data collected from October 2000 to October 2006 were reviewed, from which congenital coronary anomalies were found, and their angiographic features were studied. Results Among 1520 adults undergone coronary angiography, anomalous coronary arteries were found in 58 cases (3.82%). Depending on the anatomic characteristics of anomalous coronary arteries, these 58 cases were classified as following. Anomalies of origin and distribution were found in 26 cases (1.71%), among them separated origin of left anterior descending and left circumflex from left coronary sinus were found in 14 cases, left main trunk and left circumflex arising from right coronary sinus in 1 case for each, single left coronary artery in 2 cases, right coronary arteries arising from ascending aorta in 4 cases, from left coronary sinus in 3 cases, and from posterior coronary sinus in 1 case, respectively. Anomalies of coronary termination were observed in 11 cases (0.72%), and all of them were coronary artery fistulas. Anomalies of intrinsic coronary arterial anatomy in 21 cases (1.38%), among them myocardial bridge in 18 cases, hypoplasia of left circumflex artery in 2 cases, and sinus node artery arising from left posterior ventricular branch in 1 case. No anomalous collateral vessels were found. Conclusion Coronary angiography is one of the important methods of detecting anomalous coronary arteries. Classification based on the anatomic characteristics can help clarify the pattern and incidence of congenital anomalies of coronary arteries in adalts.

Background and purpose:Matrix metalloproteinase11(MMP-11)is an interesting member of the MMP family,and its overexpression has been demonstrated in human cancers such as non-small cell lung cancer and oesophageal adenocarcinoma.Furthermore,strong MMP11 gene expression is correlated with both increased aggressiveness of tumors and a poor clinical outcome,but there was no related reports on gastric cancer.We focussed our study on the significance of MMP-11 expression in gastric cancer.Methods:MMP-11 was selected and confirmed at both mRNA and protein level in 130 cases of gastric cancer serum specimen by RT-PCR,enzyme-linked-immuno-sorbent-assay(ELISA)techniques,respectively.Results:The total positive rates of serum MMP-11 mRNA in gastric cancer and healthy people were 68.4% and 5%,respectively.Our data demonstrated that MMP-11 protein levels in gastric cancer were(44?27)ng/ml,significantly higher than those in control subjects(P=0.001).MMP-11 protein levels in 30 cases with recurrence were(51?27)ng/ml and(27?28)ng/ml in 30 patients without recurrence.MMP-11mRNA positive expression was consistent with MMP-11 protein levels in gastric cancer patients.Conclusions:Serum MMP-11 may play an important role as a biomarker in diagnosis and prediction of recurrent gastric cancer.

The repair of severed tendons within the digital sheath constitutes a complicated surgical problem. The injury and adhesion of the tendons are an important factor for functional return in the hand. On the basis of experimental study, 7 cases of injuries of flexor digitalis tendons have been treated by using silastic artificial tendons since 1982. During the operation the tendon graft was ensheathed in a porous filmy silastic tube, including the sites of anastomosis. This technique can prevent adhesion between tendon and its surrounding tissues. The operation can be performed in one stage. The operative procedure and its indication, reconstruction of the pulley system and the gliding function of the tendon were discussed.
