Objective To explore the effect of TLR2 on collagen Ⅰ(colⅠ) in adipose tissue of high-fat-diet induced obese mice.Methods Male C57bl/6J mice and TLR2 knockout mice were divided into groups according to high fat diet or normal chow.Total collagen, TLR2, colⅠ, MMP1, MMP2, TIMP1, colⅠα1 mRNA and colⅠα2 mRNA in adipose tissue were measured at the end of the experiments.Results Total collagen, TLR2, colⅠ, MMP2, TIMP1, colⅠα1 mRNA, and colⅠα2 mRNA in adipose tissue increased while MMP1 in adipose tissue decreased in mice with high fat diet.Decreased levels of total collagen, colⅠ, MMP2, TIMP1, colⅠα1 mRNA and colⅠα2 mRNA in adipose tissue were detected in TLR2 gene knockout mice with high fat diet.However, there was an increased level of MMP1 in TLR2 gene knockout mice with high fat diet.Conclusion In high-fat-diet induced obese mice, deposition of colⅠ in adipose tissue seems to be alleviated by TLR2 gene knockout via MMP1 and TIMP1.

Conclusion The formulation screened out for the dispersible tablets of breviscapinum is suitable for the production on a large scale.

OBJECTIVE: To evaluate the diagnostic value of multi-slice spiral CT (MSCT) for plasma cell mastitis. METHODS: Radiographs of MSCT for forty-six patients with plasma cell mastitis diagnosed by pathological examination were reviewed. RESULTS: The findings of MSCT of plasma cell mastitis could be divided into four types, including the inflammation type, the abscess type, the sinus and fistula type, and the mixed type, and each type had its radiographic characteristics. CONCLUSION: MSCT is helpful for diagnosing plasma cell mastitis and should be used as an examination of first choice for the patients.

Objective To evaluate the clinical application of the fistulography of multi-slice spiral CT(MSCT)in the diagnosis of anal fistula.Methods A total of 28 patients who were verified operatively of fistula in ano underwent preoperative fistulography of MSCT.The multi-planar reformation(MPR)and surface shadow display(SSD)images were generated and analyzed retrorespectively.Results There were 8 cases with perianal abscess and 20 cases with anal fistula in 28 patients.Complex fistula was diagnosed in 16 cases,and simple inter-sphincteric fistula was found in 4 cases;the inner orificiums of anal fistulas were revealed accurately with MPR images in 18 cases.Conclusion The fistulography of MSCT is valuable for preoperative assessment of anal fistula,in particular for investigation of the inner orificiums of anal fistulas with MPR.

Objective: To determine the inhibitory effects of anti-bone sialoprotein(BSP) antibody on human breast cancer cells adhering to bone matrix in vitro.Methods: Expression of BSP in 3 different cancer cell lines(bone seeking breast cancer cell MDA-MB-231-BO,lung adenocarcinoma cell SPCA-1 and colon carcinoma cell LOVO)was detected immunohistochemically.Cells adhering test was carried out to investigate the adhering of the 3 different cancer cell lines to mouse bone matrix in vitro and the inhibitory effect of anti-BSP antibody on MDA-MB-231-BO cells adhering to mouse bone matrix;Enzyme-linked immunosorbent assay was carried out for quantitative detection of TGF-?.Results: BSP immunostaining was positive in MDA-MB-231-BO cells and negative in SPCA-1 and Lovo cells.The number of MDA-MB-231-F10 cells adhering to mouse bone matrix was significantly more than SPCA-1 or Lovo cells(P

Wuhan Pu Ai Hospital implemented the pharmaceutical direct supply mode since October 2006 as an experiment.The pilot proved the mode as successful in reducing drug costs proportion,promoting rational use of drugs,and raising business volume of the hospital.Authors also recommend to further efforts in drug supply price supervision mechanism,government subsidy mechanism,direct supply catalogue and drug supply mode among others.Other recommendations include innovation in directly supply mode,hospital internal reform,packaged performance appraisal and incentive mechanism for medical workers,and building a ceiling mechanism for total medical expense control.

ObjectiveUsing large sample clinical study to reevaluate the safety and efficacy of recombinant human growth hormone(ANSOMONE) in treating pediatric growth hormone deficiency(GHD).Methods1012 cases were administered with ANSOMONE at a dose of 0.1 IU · kg-1 · d -1 in bedtime for 6 months.The alteration of mean height,growth rate,height standard deviation scores,bone age,and anti-GH antibody and occurrence of adverse effects were observed.ResultsThe growth rate was promoted from ( 2.50 ± 0.85 ) cm/year to ( 13.44 ± 4.27 ) cm/year,the net growth rate was( 10.94 ±3.69)cm/year.There was significant difference between the pre-treatment and post-treatment patients ( P ＜ 0.01 ).The post-treatment anti-GH antibody positive rate was 13.34％,which had no obvious effect on the efficacy.Few patients exert transient inflammation reactions,which disappeared with any treatment.ConclusionANSOMONE had significant efficacy,and could promote the height increase obviously.It had good safety without any obvious side effect and early-maturing effect.

Objective To investigate the hospital mortality of rheumatic heart disease (RHD)and major cause of death. Methods One hundred and thirty patients with RHD prepared to take valve replacement from January 2006 to November 2009 were involved in this study. They were divided into two groups according to all clinical data: death group (10 cases ) and survival group (120 cases ). The clinical data and complications were collected, and the hospital mortality and their causes were analyzed with Logistic regression analysis. Results Univariate analysis: total bilirubin and indirect bilirubin levels in death group [(30.31 ± 19.10), (22.38 ± 17.34) μmol/L] were significantly higher than those in survival group [(19.47 ± 8.61),(12.92 ± 7.30) μmol/L] (P ＜ 0.01). The incidence of postoperative complications,history of cerebral infarction and cardiovascular complications in death group were significantly higher than those in survival group (P ＜0.01). The Logistic regression analysis showed that the postoperative complications was an independent risk factor for hospital mortality (P =0.002). Conclusions RHD with postoperative complications is identified as an independent predictor of hospital mortality. It is very important to enhance the treatment and care during hospitalization.

BACKGROUND:Phytohemagglutinin (PHA) can stimulate the peripheral blood mononuclear cells (PBMCs) into cellcycle, and cause their immune activation, which is a common immune proliferation model. However, the role of non-PBMC ingredient of peripheral blood is unclear, as wel as the expression of endothelial cells related cytokines. OBJECTIVE:To study the effect of whole blood culture and PBMCs alone culture with PHA on the PBMC proliferation and apoptosis, expression of inflammatory cytokine and endothelial cellsecreted cytokine markers. METHODS:Morphological changes of PBMCs separated from normal karyotype human peripheral blood individual y cultured with or without PHA were observed. The PBMCs were col ected by whole blood culture or PBMC separated culture. mRNA was extracted for the fluorescence quantitative RT-PCR, which was applied to detect the cellproliferation, apoptosis, and expression of inflammatory cytokine and endothelial cellsecreted cytokines. The statistic analysis was used for the significance explication. RESULTS AND CONCLUSION:PBMCs alone cultured ere different from those undergoing whole blood culture. The PHA could up-regulate the gene expression of Ki67, proliferating cellnuclear antigen, Caspase 3, interferon-γ, tumor necrosis factor-βand interleukin-6, but down-regulate Protein C. This indicted that PHA could promote the proliferation and apoptosis of PBMCs and up-regulate the expression of inflammatory cytokines, but down-regulate the expression of endothelial cells secreted coagulation cytokines.
