Objective　To explore the development of endogenous CO and its mechanisms in asthma.Methods　50 guinea pigs were equally separated 5 groups.After the models of asthmatic guinea pigs were established in 4 groups,3 groups of them were treated with dexamethasone,the specific stimulator(hemin)and inhibitor(Sn-PP)of HO-1 respectively.The rest of groups were asthmatic one and normal control one(NCG).From all tested animals,the COHb in blood and lung HO-1 activity were examined,the lung tissues were pathologically observed and immunohistochemically stained.Results　In asthmatic and hemin stimulated groups,the levels of COHb with enhanced expression of lung HO-1 and their activity were significantly increased compared with NCG(t=4.43～9.97,P＜0.01).For example,the lung HO-1 activities in asthmatic group were (881±361)pmol/(mg*pro*h),COHb (4.94±2.15)% respectively.In dexamethason prevented and Sn-PP inhibited groups,however,all determined levels were markedly reduced compared with asthmatic group(P＜0.01).Conclusion　The increased HO-1 had resulted in the growth of endogenous CO in asthma.

To study the characteristics of pharmacological effects of property combinations of traditional Chinese medicines (TCMs) distributing in the stomach meridian based on medicinal property combination, in order to further define the association relationship between properties of TCMs and their pharmacological effects, and build a bridge for the interpenetration and combination between the medicinal property theory of TCMs and their pharmacological effects. On the basis of the studies on the medicinal property theory of TCMs distributing along the kidney meridian and their pharmacological effects, efforts were made to collect relevant data for medicinal properties and pharmacological effects and mine the characteristics of pharmacological effects that were corresponding to relevant medicinal property combination by processing materials related to medicinal properties and pharmacological effects with the association rules method. According to the analysis, TCMs distributing along the kidney meridian with different medicinal property combinations were significantly differentiated in the pharmacological effects, but shared identical pharmacological effects, such as immunological enhancement. In this study, TCMs distributing along the kidney meridian with different medicinal property combinations were taken as the carriers to closely integrate the traditional Chinese medicine theory with the modem study achievements, lay a solid foundation for further developing and enriching the traditional Chinese medical property theory, while providing a new perspective on the development of modem medicine.

Objective: To develop a cross-culture revision of VDI created by Crites. Methods: A total of 900 college students were tested at ramdom with VDI. Results: ①Item analysis confirms that the quality of items is high; ②Cronbach ? coefficients, and the test -retest stability coefficients ranged from 0.660 to 0.840, and 0.557 to 0.761, respectively; ③There were significant differences between post graduates and undergraduates. Conclusion: The psychometric properties of the inventory developed in the current study are acceptable.

Objective To explore the experience of operative cooperation of trans-sternocostal triangle hand-assisted double lung metastatic tumor resection.Method The clinical data of 54 patients undergoing trans-sternocostal triangle hand-assisted double lung metastatic tumor resection were retrospectively analyzed from January 2005 to December 2005.Results The operations were all successful,with blood loss of 10~700 mL,operation time of 40~300 min,averaged(130.3+43.0)mins.One hundred and seventy eight malignant tumor lesions were removed.No serious complications occurred.Conclusion The key points to ensure thesuccessful operation were as follows:preoperation of special equipment,reasonable position,intraoperative strict aseptic operation,fixing of endoscopic incision suturing instrument,and accurate cooperation at all procedures.

Objective To investigate the clinicopathologic features and prognostic analysis of intrahepatic mucinous cholangiocarcinoma (IMCC) and intrahepatic cholangiocarcinoma (ICC).Methods The retrospective cohort study was adopted.The clinicopathological data of 20 patients with IMCC and 51 patients with ICC who were admitted to the Fujian Provincial Hospital from March 2003 to March 2014 were collected.The observation indicators included (1) clinicopathologic features:gender,age,clinical symptoms (fever,jaundice,abdominal pain and peritoneal effusion),preoperative laboratory examination [alanine transaminase (ALT),aspartate transaminase (AST),direct bilirubin (DBil),carcinoembryonic antigen (CEA),CA19-9 and alphafetoprotein (AFP)],operation methods (radical resection,palliative resection) and pathological features (tumor location,lymph node metastasis,vascular invasion and pathological stage).(2) The follow-up of outpatient examination and telephone interview was performed to detect the survival of patients up to March 2015.Measurement data with normal distribution were represented as x-± s and comparison between groups was analyzed using t test.Count data were analyzed using the chi-square test.The survival curve was drawn by Kaplan-Meier method,and the survival rate was analyzed using the Log-rank test.Result The numbers of patients with fever,jaundice,elevated level of AST and DBil,lymph node metastasis,vascular invasion and numbers of patients with stage 0,Ⅰ,Ⅱ,Ⅲ,Ⅳ were 13,11,10,11,3,1 and4,6,2,6,2 with IMCC,12,10,9,2,22,36 and 0,14,5,3,29 with ICC,respectively,showing statistically significant differences in the above indicators (x2=10.830,8.639,7.672,25.059,8.036,24.765,26.601,P ＜ 0.05).All the patients were followed up for a median time of 14 months (range,1-118 months).The survival time and 1-,3-,5-year survival rates were (55 ± 8)months,94.4％,44.0％,16.7％ in 20 patients with IMCC and (30 ±6) months,36.5％,12.5％,4.0％ in 51 patients with ICC,respectively,showing a statistically significant difference (x2 =8.126,P ＜ 0.05).Conclusion The patients with MICC are more easily complicated with fever,jaundice and liver dysfunction,while they have less lymph node metastasis and vascular invasion,earlier pathological stage and better prognosis compared with patients with ICC.

Objective To construct the recombinant plasmid carrying small interfering RNA(siRNA) to CXCR4 and observe dumbness effect of chemokine receptor gene CXCR4 suppression by RNA interference(RNAi),and explore the new method of more efficacious therapeutic possibilities for HIV-1.Methods Small interfering RNAs targeting CXCR4 gene were designed by using software.The complement form was obtained by annealing and interted into vector Psilencer3.1-H1neo.After sequencing,MT4 cells were transfected using the plasmid vector.RT-PCR and flow cytometry detection were used to evaluate the suppression of CXCX4 expression in different groups.Results The recombinant plasmid had the correct special fragments and DNA sequence detected by PCR,electrophoresis and DNA sequencing;The siRNA obviously suppressed the expression of CXCR4.When transfected with plasmid vector for 48 h,the inhibitory rate was 70%,compared with control and negative groups,there were significant differences(P

Objective:To determine the in vitro release of two kinds of Changankang Pellets (Radix Astragall, Rhizama coptid) coated with Surelease and Eudragit respectively and verify their colon-targeted release in vivo through X-ray photography. Methods: Changankang Pellets were made by mixing the medical BaSO 4 powder and appropriate drugs together according to original produce and coat methods. After determining their in vitro release, they were tested in vivo by 2 volunteers. X-ray films were taken after appropriate time and analyzed to determine the location and status of these pellets inside healthy objects. Results: Pellets made by this way can carry drugs through stomach, intestine and targeted-release them in colon; the coating combined with pH-dependent and time-dependent Eudragit thin layer has better results. Conclusion: X-ray radiography applying BaSO 4 powder could be taken as a quality control method for colon-targeted release drugs. The preliminary results showed that Changankang Pellets met the requirements of colon-targeted release.
