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 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.

OBJECTIVETo explore the biological characteristics of fibroblasts in adult granulation tissue in vitro, including cell viability, CD phenotypic, factor and protein expression, and differentiation, so as to facilitate further research of the role of fibroblasts in early wound healing.
METHODSFibroblasts were isolated from human granulation tissue and cultured by mechanical and enzymatic digestion method. The cell morphology and proliferation were observed under inverted phase contrast microscope. The first and third passages of cells' growth curve were drawn respectively. The surface markers (CD105, CD73, CD90, CD44, CD34, CD45, CD19, CD11b, HLA-DR) of the first and third passage fibroblasts were identified by Flow Cytometry. And the expression of Vimentin, CK19, CD31 and Factor VIII were detected by immunocytochemistry.
RESULTSPrimary cultured fibroblasts were short spindle, polygonal and irregular in shape. The morphology of fibroblasts were uniform by repeatedly passage cultured in vitro and showed spindle-shaped. The proliferative capacity of the fibroblasts were not significantly different, with logarithmic growth phase. From 1 to 4 days, The primary and third passage cells' proliferation was no difference (P > 0.05), After the five days, the proliferative ability of third generation was better than the primary passage (P < 0.01). All fibroblasts highly expressed mesenchymal stem cells' surface markers CD105, CD73, CD90 and CD44, and didnt express hematopoietic stem cells' surface markers CD34, CD45, CD19, CD11b and HLA-DR. The expression of mesenchymal stem cells' surface markers in third generation of cells were increased significantly. Immunocytochemistry showed positive expression of Vimentin, CD31, and negative expression of CK19 and Factor VIII.
CONCLUSIONSFibroblasts in human granulation tissue show the biology characteristics of Mesenchymal Stem Cells. Some biological markers of endothelial cells are expressed in fibroblasts in granulation tissue. The fibroblasts may play an important role during the process of endothelial to mesenchymal transformation in early wound healing.

Objective To evaluate the sensitivity and specificity of histopathologie analysis vs cytomegalovirus (CMV) detection for the diagnosis of CMV-infected hepatitis post liver transplantation. Methods Twenty-five biopsies with CMV infection and twenty-five without CMV infection were collected. Histopathologic observation, immunohistochemical staining and virus detection were performed on both groups to evaluate the sensitivity and specificity of these examinations for the diagnosis of CMV-infected hepatitis. Results The detection rate of microabscess, aggregation of monocyte and rnacrophage, and cytomegalic change in CMV infection group was higher than that in the group without CMV infection (P<0.05), but there was no significant difference in intranuclear inclusion and eosinophilic body between the two groups (P>0.05). The sensitivity and specificity of IHC and PCR for CMV detection were 20% and 100%, 72% and 84%, respectively. Conclosions CMV detection with PCR combined with histological observation is the most effective diagnostic scheme for CMV disease of liver.
