The pathogenesis of ulcerative colitis (UC) is spleen-stomach weakness with dampness. Therefore, Qu-Shi (QS, eliminating dampness) is the main treatment principle. According to different pathogens, four QS methods in the UC treatment were summarized based on clinical experiences. In the clinic , the application of heat-clearing and dampness-eliminating, warm yang and dampness-eliminating, dampness-eliminating with bitter and pungent, spleen-reinforcing and dampness-eliminating. The indications should be identified for the application of principle-method-prescription-medicine. The flexible application of four methods mentioned above can increase the clinical efficacy.

Iatrogenic injury in choledocho-pancreatico-duodenal junction is usually difficult to discover in the course of operation because of its unique anatomical position. The injury can lead to postoperative chilis, fever, pain and swelling of the waist, which would easily be misdiagnosed as acute necrotizing pancreatitis. Controlling operations, such as bile and pancreatic juice separation, duodenal diverticularization, jejunal fistulation for enteral nutrition and abdominal drainage should be performed in dealing with the injury in choledocho-pancreatico-duodenal junction. Combined application of pyloric suture with absorbable thread and ligatian, gastric fistulation, ligation of the distal common bile duct and T-tube drainage is minimally invasive, and can fulfill a fully separation of bile and pancreatic juice and duodenal diverticularization. It will improve the possibility of secondary radical operation by ameliorating pyemia and general nutritional condition.

Objective To study the dinical value of serum soluble E-selectin(sE-selectin)and serum soluble P-selectin(sp-selectin)in patients with esophageal squamous cell carcinoma. MethodsThe sP-selectin and sP-selectin of the serum was measured by ELISA in 27 patients with viral encephalitis and 35 normal persons. ResultsIn patients with organ metastasissE-selectin and sP-selectin levels were significantly higher than normal(P＜0.01),In patients with organ metastasis,sE-selectin and sP-selectin levels increased more pronounced.No visceral metastasis in patients with esophageal cancer,postoperative serum sE-selectin and sP-selectin levels significantly decreased compared with the preoperative(P＜0.01),there are organ metastasis in patients with esophageal cancer sE-selectin and sP-selectin levels decreased not obvious. ConclusionsE-selectin and sP-selectin could be used as a new tumor detection of esophageal cancer targets,and has close relatimship with the incidence of esophageal cancer,development and metastasis.

Objective:To assess clinical value of grading scale for intracerebral hemorrhage(ICH).Methods:By using the grading scale for ICH suggested by Hemphill and colleagues, 205 patients with acute ICH presenting to our department during 2000～2001 were studied retrospectively.Results:Thirty-mortality of ICH patient increased steadily with ICH Score.Conclusion:The grading scale for ICH is a simple amd reliable method of ICH score,worthy of clinical application.

Objective; To test the effect of fosinopril and valsartan on cardiomyocte apoptosis and expression of Bcl - 2 and Bax in myocardium of ischemia - reperfusion (I - R) rat model. Methods; SD rats were randomly divided into four groups as follows: Sham - operation group. Ischemia - reperfusion group . Fosinopril group and Valsartan group. The TdT - mediated dUTP nick end labeling (TUNEL) method was used to detect apoptotic myocytes in different groups. Bcl - 2 and Bax expression in myocardium were analyzed by immunohistochemical technique. Results ; The number of apoptotic cardiomytocytes in Ischemia 30min - reperfusion 48 hours group were significantly more (247. 2?25.9), than those in Ischemia 30min - reperfusion 4 hours group (P

Objective:To Construct a prokaryotic expression vector of cystatin C(Cys C)to provide a basis of purify Cys C protein produced by the expression system.Methods:Total RNA was isolated from HL-60 cells,and human Cys C gene was amplified with RT-PCR.The cDNA fragment was cloned into pET32a(+)vector,which was confirmed with sequencing and electrophoresis.Results:The result of electrophoresis showed that Cys C had been cloned into pET32a(+)vector,and the result of.DNA sequence analysis also showed the cloned Cys C gene sequence was completely correspondent to GeneBank data.Conclusion:The prokaryotic expression vector of cystatin C(Cys C)was obtained,providing a basis of purification of Cys C protein produced by the expression system.

Objective To study the adhesion and proliferation of rabbit bone marrow mesenchymal stem cells(BMSCs) on the HA/TCP bone graft scaffold.Methods BMSCs were harvested from the iliac bone and obtained by using adhesive culture method.BMSCs were induced with osteogenic medium,at the 7th day,the cells were stained by the calcium cobalt method to show the activities of alkaline phosphatase(ALP).At the 10th day,the mineralized nodules of osteoblasts stained with chinalizarin.Otherwise BMSCs were induced with adipogenic medium,and at the 21st day the cells stained with oil red O.We cultured the BMSCs on the surface of a matrix scaffold with osteogenic medium.The morphologic characters were checked by light microscopy,fluorescence microscopy and scanning electronic microscopy,and the proliferation of BMSCs were assayed using the MTT test.Results At the 7th day after osteoblastic induction,ALP was strongly positive,and at the 10th day,mineralized nodules stained with chinalizarin were jacinth.At the 21th day after adipogenic induction,the adipocytes were stained with oil red O.BMSCs grew well around or in pores of the HA/TCP bone graft scaffold and could be seen using both fluorescence microscopy and scanning electron microscopy.The MTT test assay showed that the HA/TCP couldn't inhibit the proliferation of BMSCs.Conclusion BMSCs have a good biocompatibility with a HA/TCP bone graft scaffold.

Objective: To study the effect of acute hypoxia with simulated high altitude on the expression of orexins in rats hypothalamus. Methods: Rats were exposed to different high altitude(3 000 m,(4 000) m,5 000 m and 6 000 m for 8 h daily) in a hypobaric chamber.The expression of orexins in rat hypothalamus was determined by immunohistochemistry and the pathology changes of rat hypothalamus was observed with transelectricity. Results: The number of orexin-A immunoreactive positive cells in hypothalamus decreased obviously with hypoxia for 1 day(P

Objective To study the differences of electrolytes,C-reactive protein in different type,gender and recur- rent of febrile convulsion.Methods 174 cases of children febrile convulsion were collected.We detected the electro- lytes,C-reactive protein respectively and analyzed their relationship.Results In children febrile convulsion,the lev- els of the electrolytes,C-reactive protein had nothing to do with the type,gender and recurrent of the febrile convul- sion.Conclusion We should treat routinely the children who suffered from febrile convulsion without considering the type,gender and recurrent.

Objective To study the relationship between HCV chronic infection and expression of CXC chemokines mRNA.Methods The levels of IL-8,IP-10 and Mig mRNA in peripheral blood mononuclear cells(PBMC) of chronic hepatitis C patients were detected by real-time quantitative polymerase chain reaction(RT-PCR) before,and 3,6 months after combined therapy of interferon-?(IFN-?) and Ribavirin.The rate of chemokine/GAPDH was regarded as the extreme level of chemokine.Results The mean level of HCV-RNA and expressive levels of IL-8,IP-10,Mig mRNA in peripheral blood of HCV chronic infection were 2.09?10~(6)copies/ml,and(1.243 7?0.071 2),(0.682 8?0.073 8),(0.668 3?0.075 4),with significant difference with those of normal controls(P0.05).Conclusion The expressions of IL-8,IP-10 and Mig mRNA in PBMC are high in patients with chronic hepatitis C,and associated with the replication level of HCV,and less associated with the gene type of HCV.IFN-? can effectively restrain the replication of HCV and down-regulate the levels of IL-8,IP-10 and Mig mRNA near to normal level in patients with chronic hepatitis C.IFN-? plays an important role in down-regulating inflammation response and controlling the development of the patients' condition.
