Objective To investigate the effects of Astragalus polysaccarides (APS) on 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis in rats. Methods Forty male Sprague-Dawley rats were randomly divided into five groups (n = 8 ): control group, TNBS group, low-dose APS group, high-dose APS group, and prednisone group. Experimental colitis was induced in rats by enema administration of TNBS. Rats in APS and sions and histological damages were determined, and the activity of myeloperoxidase (MPO) was measured in the excised colonic tissues. Cytokine levels including interleukin (IL)-4 and IL-10 were determined by enzyme-linked immunosorbent assay. Results Both macroscopic lesions and histological colonic damages induced by TNBS were reduced by low-dose APS treatment. These were accompanied by significantly attenuated colonic MPO activity (P = 0. 03) and the increase of IL-4 and IL-10 levels. The macroscopic lesions and MPO activities of high-dose APS group were higher than TNBS group, histological damage and level of IL-4 were lower, and level of IL-10 was higher, but all without statistical significance. Levels of IL-4 and IL-10 were lower than those of TNBS group, but there was no significant difference between prednisone group and TNBS group. Levels of IL-4 and IL-10 were significantly lower in prednisone group than in control group ( P = 0. 049, P = 0. 001 ). Conclusions Different doses of APS have different effects on TNBS-induced colitis. Lower dose of APS has the therapeutic potential inexperimental colitis, while higher dose of APS may aggravate the disease.

Objective To investigate the effect of Astragalus polysaccharides (APS) on 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis in rats and on dendritic cells (DCs) in mesenteric lymph nodes.Methods Forty-four male Sprague-Dawley rats were randomly divided into four groups (n = 11) using simple random sampling: normal control group, TNBS group, APS group, and 5-aminosalicylic acid (5-ASA) group.Experimental colitis was induced in rats by TNBS enema in the last three groups.Rats in APS and 5-ASA groups were treated by gavage with APS (0.75 g ? kg-1 ? d-1) and 5-ASA (100 mg ? kg-1 ? d-1) on the 10 consecutive days following TNBS administration.The rats were then sacrificed and the colonic inflammatory scores of rats were measured, including the scores of disease activity index ( DAI) , macroscopic lesions, and histological damages,as well as the activity of myeloperoxidase (MPO).The expressions of major histocompatibility complex class Ⅱ(MHC Ⅱ ) and costimulatory molecule CD86 on DCs were determined by flow cytometry.Results Compared with the TNBS group, APS group had significantly decreased scores of DAI ( P = 0.007 ) , macroscopic lesions (P =0.017), and histological damages (P = 0.016).Moreover, its level of the activity of MPO dropped but without statistical significance (P =0.183).TNBS group had significantly higher expressions of MHC Ⅱand CD86 molecules on DCs than the normal control group (P = 0.005, P = 0.008), APS group (P = 0.023, P = 0.018), and 5-ASA group (P = 0.017, P=0.013).Conclusion APS may attenuate TNBS-induced colitis in rats and downregulate the activation of DCs in mesenteric lymph nodes.

Objective To evaluate the etiology, pathogenesis, clinical manifestation, imaging features, treatments and factors related to prognosis of acute spinal spontaneous hematoma.Methods The clinical data of 38 patients with acute spinal hematoma treated in our hospital from 2011 till now were analyzed retrospectively.Duration of follow-up was 6 months.The factors influencing the prognosis were analyzed.Results Acute epidural hematomas (n=29) were much more common than subdural (n=5), subarachnoid (n=1) and intramedullary (n=3).Most hematomas were located in the cervical and thoracic vertebra regions.The etiology of acute spinal spontaneous hematoma was unknown in most patients.Twenty-nine patients were dealt with surgical intervention and 9 patients were treated conservatively.After 6-month follow up, recovery rate measured by JOA score in patients of spinal injury ASIA level A and B was (51.26 ±38.97), and level C, D and E was (80.33 ±25.83), P<0.05.Recovery rate in patients with hematoma discovered in less then 24 hours treated with surgical decompression was (64.79 ±36.10), and that in those with hematoma present over 24 hours was (34.54 ±30.17), P<0.05.Conclusions Acute spinal hematoma always caused by unknown etiology, and usually manifests itself in a sudden onset of pain and neurological deficits.The early diagnosis mainly depends on MRI.Patients presenting with severe neurologic dysfunction or showing signs of progressive deficit should have immediate surgical intervention. The status of neurological deficits before surgery and the length of interval between onset and surgical intervention are associated with recovery.

Objective　To evaluate the role of transfected angiotensinⅡ(Ang Ⅱ) receptor AT1 anti-sense nucleotide (AT1A) in the expression of subtypes of AngⅡ receptor mRNA, synthesis of protein and nucleic acid in cardiomyocytes. Methods　AT1 cDNA sequence (476 bp) was cloned with RT-PCR and reversely inserted into PcDNA3.1 (5.4 kb) to construct an intact plasmid containing AT1A (PAT1A). The plasmid was then transfected into the cultured cardiomyocytes and identified with RT-PCR and Western blot. The synthesis of protein and nucleic acid identified by 3H-Leu and 3H-TdR incorporation, and expressions of AT1 and AT2 mRNA by RT-PCR, were compared between transfected and nontransfected cardiomyocytes after being stimulated with 10-7 mol/L AngⅡ for 24 h. Results　The plasmid PAT1A were successfully constructed. The AT1 mRNA and its protein were expressed significantly less in the transfected cardiomyocytes than in the control (P<0.01). In the transfected cardiomyocytes, AT1 mRNA expression was markedly decreased, but that of AT2 mRNA obviously increased (P<0.01) when compared with the nontransfected cardiomyocytes after stimulation for 24 h with AngⅡ 10-7 mol/L; no significant difference was found in 3H-Leu and 3H-TdR incorporation between them. Conclusion　After the cardiomyocytes was tranfected with AT1A, the expression of AT1 mRNA was markedly suppressed，while AT2 mRNA up-regulated at the same time. Our results indicate that AT1A blocking can not effectively interrupt the Ang Ⅱ-induced synthesis of the protein and nucleic acid in cardiomyocytes.

AIM: To investigate the protective effect of calcium antagonists on anoxia/reoxygenation (A/R) injury of cardiomyocytes. METHODS: Primary-cultured cardiomyocytes were divided into four groups, namely A/R, A/R+nifedipine(Nif), A/R+ruthenium red(Ru)+heparin (Hep) and control groups. The following parameters were measured in all groups: intracellular calcium concentration ([Ca 2+ ]i), cardiac cell viability, ATP content, lactate dehydrogenase (LDH) activity in the medium, PKC and MAPK activity and -Leucine(-Leu) incorporation. RESULTS: In comparison with A/R group, A/R+nifedipine(Nif) and A/R+ruthenium red(Ru)+heparin (Hep) groups showed a marked decrease in [Ca 2+ ]i and LDH content, and a significant increase in cell viability ,ATP content, activity of PKC and MAPK and -Leu incorporation(P

AIM: To investigate the contribution of angiotensin-converting enzyme inhibitor (ACEI) to the regulation of calpain system in infarcted myocardium. METHODS: Rat myocardial infarction (MI) model was established by permanent ligation of the left coronary artery. The treatment with the ACEI inhibitor rampril (1 mg?kg~-1 ?d~-1 ) was started 7 days prior to surgery. On day 1, 3, 7 and 14 after MI, protein levels of calpainⅠ, Ⅱ and calpastatin were determined in left ventricular free wall (LVFW), interventricular septum (IS) and right ventricule. RESULTS: CalpainⅠprotein level was increased in IS 14 d post MI, whereas the protein level of calpainⅡ was maximally increased in LVFW 3 d post MI. Rampril decreased protein up-regulation of calpainⅠ and Ⅱ, and reduced infarct size and interstitial fibrosis. Calpastatin protein expression was not affected by ACEI. CONCLUSIONS: CalpainⅠ is involved in cardiac remodelling in the late and calpainⅡ contributes to cardiac tissue damage in the early phase of MI. The heart protective effect of ACEI may be related to the inhibition of calpain system in the pathogenesis of myocardial infarction.

Objective To investigate the involvement of mitogen-activated protein kinase(MAPK)and PI3K(phosphatidylinositol 3 kinase)/ Protein kinase B(Akt) signal transduction pathways in the mechanism of myocardium remodeling in patients with congestive heart failure(CHF).Methods Thirty nine patients of mitral valve disease with CHF were randomly selected and 30 cases of healthy persons were included as controls.Cardiac function parameters were measured by echocardiography.Concentration of AngⅡ in plasma and myocardial tissues was determined by radio immunoassay.Activity of PKC was determined by using competive prote in binding method,activity of MAPK was detected by the methods of immunoprecitipation.Immunoprecitipation was used to assay the protein expression and phosphorylation of PI3K and Akt(Protein kinase B),protein expression of C-FOS and ?-skeletal-actin in myocardial tissues.Results Pathological changes of myocardial tissues in CHF with valvular heart diseaseshowed typical myocardial remodeling.The hypertrophy was dominant at early stagy of CHF,while at end stage the characteristics include disordered alignament of the myocytes,the discontinuity and dissolving of cardiomyofibrills,destroyed subcellular organs,and the hyperplasia of interstitial tissue.AngⅡ concentration in plasm and myocardial tissues in patients with CHF was higher than those in the control group(P

Objective To assess the nutritional risk of patients with inflammatory bowel disease (IBD).Methods The nutritional status of 112 IBD patients from PUMC Hospital were evaluated by Nutritional Risk Screening 2002 (NRS 2002).Using Chinese standard,a body mass index (BMI) that was lowered than 18.5 kg/m~2 according to clinical material was regarded as malnutrition,and the score was recorded as 3.The se-verity of ulcerative colitis (UC) was evaluated using True-Love criteria as mild,moderate,and severe.Crohn's disease (CD) was evaluated using Harvey-Bradshaw Index as in remission stage (≤4),moderately active stage (4-8),and severely actively stage (≥9).Results All these 112 patients,including 70 UC cases and 42 CD cases,were evaluated by NRS2002.Forty-five patients (40.2%) were judged as at the risk of malnutrition.The incidence of malnutrition was significantly higher in CD patients than in UC patients (52.4% vs.32.9%,P<0.05).It was also significantly correlated with the severity of disease.In patients with severe IBD,the rate of mal-nutrition evaluated by BMI according to clinical material was significantly lower than the rate of nutritional risk.Con-clusions The risk of malnutrition is high in IBD patients.NRS 2002 can be used for nutritional risk screening.

A method based on HPLC-ICP-MS was established to separate the reaction products of ( ethylenediamine) palladium(Ⅱ) chloride([Pd ( en ) Cl2])and 5’-deoxyguanylic acid ( 5’-dGMP). Two reaction products were detected at pH 8. 0 with 25 mmol/L phosphate buffer solution as chromatography eluent. One was the main product with HPLC retention time of 2. 8 min, the other product’s retention time was 3.2 min. According to ESI-MS(MS/MS) study, m/z=510, 511, 512, 514, 516[M+1]+ parent ions ( abundances same to palladium isotopes) were detected. Further analysis showed that the main product was[Pd( en) ( N1-5’-dGMP) ]. However the other product was hardly to be detected by ESI-MS. By using HPLC-DAD and HPLC-ICP-MS, we found that the two reaction products had the same UV absorption spectra and palladium percentage content. Combined with other groups’research, the other reaction product was deduced as dimmer, trimer or tetramer form of[Pd( en) ( N1-5’-dGMP) ]. Further study revealed that[Pd( en) ( N1-5’-dGMP) ] was easily formed in acid solution while its polymer form was generated in alkaline solution. At pH 6. 0, [Pd(en)(N1-5’-dGMP)] was formed within 12 hours with good stability. Research also revealed that the total amount of two reaction products declined as reaction pH climbed.
