AIM: To evaluate the effect of luteolin on ulcerative colitis in experimental animals. METHODS: The mouse model of acute colitis was induced by instillation of dinitrochlorobenzene (DNCB) /alcohol. Luteolin (1, 10 and 50 mg?kg~(-1)) were orally administrated to mice for 3 days. Diarrheas, colon weight index, macroscopic damage in the colon were observed and the activity of MPO and the content of PGE_2 in colon were also examined. RESULTS: The diarrhea and the colon weight in- dex were reduced and the macroscopic damage in the inflammatory colon was effectively attenuated by luteolin. The elevated level of MPO and PGE2 were also significantly decreased. CONCLUSION: Luteolin can effectively inhibit the inflammatory infiltration, bleeding and proliferation in experimental ulcerative colitis.

Objective Hypercellularity in proliferan've glomerulonephritis can result from either increased proliferation or the failure of cells to undergo apoptosis in response to stimuli. Increasing evidence supports that alterations in the control of cell survival are important in the pathogenesis of proliferative glomerulonephritis. Methods Apoptotic cells in the glomeruli have been analyzed by the in situ end labeling (ISEL) of TdT from patients diagnosed with membranoproliferative glomerulonephritis (MPGN, n = 12), type IV lupus nephritis (LN, n = 15) and acute postinfectious glomerulonephritis (APGN, n = 13) in the present study. In addition, the proliferating cell nuclear antigen (PCNA)-positive proliferating glomerular cells were observed by immunochemical 4 layer PAP method in these patients. Results The ratio of proliferating and apoptotic cells was the highest one in patients with MPGN (3.91) as compared to APGN (1.28) and LN(1 .02). The extends of increasing apoptotic cells in the glomeruli were different among patients with MPGN,, APGN and LN, although all of them showed extremely glomerular hypercellularity. The number of apoptotic glomemlar cells was significantly higher in patients with APGN (1.16?0.35) than those with MPGN (0.12?0.16) as well as LN patients (0.35 ? 0.20). Conclusion Apoptosis is essential in the resolution of glomerular cellularity together with the remodeling processes. Intense proliferations without increment in apoptosis are the characterisitics of MPGN and LN associated with their renal histological changes and prognosis.

Objective To study the diagnosis and treatment of adrenal tumors. Methods 1 006 cases of adrenal tumors treated from 1957 to 2000 were reviewed. Results Of the 1 006 cases of adrenal tumors,845(84.0%) were functional with 12(1.4%) malignant and 161(16%) nonfunctional with 11( 6.8%) malignant.There were 180 incidentaloma including 19 pheochromocytoma.A total of 996 tumors have been surgically removed and 10 cases underwent surgical exploration only.The total mortality rate was 0.3%. Conclusions Adrenal tumors occurred mostly in patients of 30~50 years of age.The prevalence of Cushing syndrome was more in females than in males.Ultrasonography and CT are the method of choice for the localization of the tumor whereas hormone levels should be determined both in the symtomatic and asymtomatic patients with adrenal tumors.Functional adrenal tumors and solid incidentaloma of large size should be surgically removed while asymtomatic incidentaloma less than 3 cm in size could be observed and followed up and surgery might be undertaken when indicated.

OBJECTIVEThis study aims to compare and determine a kind of nano-hydroxyapatite composite material with good antibacterial efficacy on Enterococcusfaecalis (E. faecalis) in vitro.
METHODSWe investigated the antimicrobial activity of four kinds of nano-hydroxyapatite composites, namely, silver/hydroxyapatite composite nanoparticles (Ag/nHA), yttrium/hydroxyapatite composite nanoparticles (Yi/nHA), cerium/hydroxyapatite composite nanoparticles (Ce/nHA), and hydroxyapatite nanoparticles (nHA), against E. faecalis in vitro using the agar diffusion and broth dilution method by measuring the growth inhibition zone and the minimum inhibitory concentration (MIC), respectively.
RESULTSThe agar diffusion test results showed that Ag/nHA displayed an obvious growth inhibition zone, whereas Yi/nHA, Ce/nHA, and nHA showed no influence on E. faecalis. The MIC value of Ag/nHA was 1.0 g.L-1, and the three other materials had no effect on E.faecalis even at the high concentration of 32.0 g.L-1.
CONCLUSIONAg/nHA display a potential antimicrobial efficacy to planktonic E.faecalis. Whereas, the three other kinds of nano-hydroxyapatite composites (Yi/nHA, Ce/nHA, nHA) show no influence.

Objective To evaluate the use of keyhole dynamic magnetic resonance (MR) imaging in evaluation of pituitary microadenomas. Methods Fifty three patients with pituitary microadenomas proved by operation or clinical findings such as headache, amenorrhea, lactating, fat or acromegaly were retrospectively studied on dynamic MR, conventional contrast enhanced MR, and unenhanced MR. Then the image data were analyzed by two experienced doctors who didn′t know the details and three degrees were made as follows: grade 0, no evidence of the tumor; gradeⅠ, asymmetry signals in the pituitary; and gradeⅡ, nodulated or sheets signals in the pituitary. The grading data were compared with statistical methods. Results In dynamic MR grading system: grade 0 was revealed in 1 patient, gradeⅠ in 29 patients and gradeⅡ in 23 patients. In conventional enhanced MR: grade 0 in 26 patients, grade Ⅰ in 17 patients and gradeⅡin 10 patients. In conventional unenhanced MR: grade 0 in 39 patients, grade Ⅰin 10 patients and grade Ⅱ in 4 patients. The diagnostic rate of dynamic MR, conventional enhanced MR, and unenhanced MR was 98.1%, 51.9%, and 26.4%, respectively. ( P

This paper is aimed to assess the effects of red blood cell (RBC) transfusion on clinical outcomes in cardiac surgery. Trials were identified by computer searches of the Pubmed, MEDLINE, Cochrane Library (Issue 10, 2012), from January 1980 to October 2012. References in identified trials and review articles were checked and experts contacted to identify any additional trials. The homogeneous randomized controlled trials (RCTs) were analyzed with RevMan 5.1 software. Five trials involving a total of 1,203 patients were identified. The results of meta-analyses showed that restrictive transfusion strategies reduced the risk of receiving a RBC transfusion (MD = - 1.46, 95% CI -1.18(-) -1.1) and the volume of RBCs transfusion (RR = 0.69, 95% CI 0.53-0.89). No significant difference was noted between the two strategies in terms of mortality, adverse events and hospital or intensive care length of stay. Based on the results mentioned above, one can draw a conclusion that restrictive transfusion strategies reduced the risk of receiving RBC transfusion and the volume of RBCs transfused. Restrictive transfusion strategies did not appear to impact on the rate of adverse events and hospital or intensive care length of stay, compared to liberal transfusion strategies.

OBJECTIVETo investigate the dynamic features of angiogenesis in residual tumors after high intensity focused ultrasound (HIFU),and to determine the temporal effect and mechanism of hypoxia inducible factor-2 alpha (HIF-2a) in the angiogenic process of residual tumors.
METHODSXenograft tumors of HepG2 cells were generated by subcutaneously inoculating athymic BALB/c nu/nu mice with the hepatoma cells.About 30 days after inoculation,all mice (except in the control group) were treated by HIFU and assigned randomly to the following 7 groups according to various time intervals post-treatment:1st,3rd,5th day and 1st,2nd,3rd,4th week when the residual tumor tissues were obtained from the experimental groups.Protein levels of HIF-2a and vascular growth factor A (VEGF-A) were quantified by immunohistochemistry and western blotting,and mRNA levels were measured by (real-time quantitative) qPCR. Microvascular density (MVD) was calculated by counting the CD31-positive vascular endothelial cells identified by means of an immunohistochemical staining method.
RESULTSCompared with results from the control group,the protein and mRNA levels of HIF-2a expression reached the highest level in the experimental mice at the 2nd week (P=0.000 and P < 0.01 respectively),and were decreased thereafter(3rd week and 4th week, P=0.000 and P < 0.05).VEGF-A expression in the residual tumor tissues group that received HIFU was significantly decreased,compared with the control group,at all time points uPto 1 week (all P=0.000 and P < 0.01),but the levels increased compared to controls in the 2nd through 4th week (all P=0.000, P < 0.05). Similar results were obtained for MVD.
CONCLUSIONHIFU treatment can inhibit angiogenesis in residual hepatoma tissues in the short-term (1 to 2 weeks post-treatment) in mice with hepatocellular carcinoma,but can promote angiogenesis overtime (2 to 4 weeks post-treatment); the angiogenic process may involve the HIF-2α/VEGFA pathway.
