Objective To explore the protective effect of atorvastatin on irradiated endothelium and the thrombomodulin(TM)expression.Methods Cultured human coronary artery endothelial cells(HCAEC)and human umbilical vein endothelial cells(HUVEC)were treated by atorvastatin at the final concentration of 10 μmol/ml for 10 min,and then irradiated with 2 and 25 Gy.Cell cycles status and TM expression were quantitatively measured by flow cytometry 24 hours after irradiation.Protein C activation in endothelial cells was also assessod.Results After administration with atorvastatin for 24 h,the TM expression increased by 77%,59% and 61% in normal control group,2 Gy group and 25 Gy group,respectively(t=27.395,26.420,58.065;P=0.000).The protein C levels decreased by 23% and 34% compared with the normal group post-irradiation to 2 and 25 Gy,but increased by 79% and 76% compared with the irradiated control group after administration with atorvastatin.The rates of cell apoptosis decreased by 6% and 16% in 2 Gy and 25 Gy groups,respectively after administration with atorvastatin for 24 h(t=4.178,17.863;P=0.000).Conclusions Atorva statin can protect endothelia cell from irradiation-induced apeptosis by increasing TM expression and protein C activation.

Objective To analyze the consistency of transcutaneous perianal ultrasonography (TPUS) and pelvic magnetic resonance imaging (MRI) in diagnosing perianal lesions of Crohn's disease (CD), and to evaluate the value of transcutaneous perianal ultrasonography in detecting perianal lesions of CD. Methods A cohort of 102 patients diagnosed as Corhn's disease were enrolled from August 2008 to August 2010. Perianal abscess and fistula of these CD patients was diagnosed by ultrasonography and MRI system. Statistics was performed with SPSS 11.5 software for X2 test. The consistency was analyzed with Kappa test. Results The mean onset time of perianal lesions in CD was -0.443 year (95％CI:-1.659～0.773 year) before typical symptoms showed up. There was no significant difference in detecting perianal lesions of CD between transcutaneous perianal ultrasonography and pelvic magnetic resonance imaging (P ＝ 0.706, Kappa ＝ 0.541). If pelvic magnetic resonance imaging was considered as the golden standard in detecting perianal lesions of CD,the sensitivity (Sen), specificity (Spe), Youden's index, positive predictive value (PPV) and negative predictive value (NPV) of TPUS were 72.73％, 82.61％, 0.55, 66.67％ and 86.36％ respectively.Furthermore, there was no significant difference between transcutaneous perianal ultrasonography and pelvic magnetic resonance imaging in detecting perianal abscess ( P ＝ 0.706, Kappa ＝ 0.496) and fistula (P＝0.655, Kappa＝0.546) of CD. Conclusions Perianal lesions occur in the entire course of CD. There was favorable consistency between transcutaneous perianal ultrasonography and pelvic magnetic resonance imaging in detecting perianal abscess and fistula of CD. Transcutaneous perianal ultrasonography can be used as an additional method in detecting and evaluting perianal lesions of CD.

Objective To explore the early diagnosis and risk factors for judging prognosis of acute respiratory distress syndrome (ARDS),and to provide references for clinical intervention.Methods Using the method for prospective cohort study,clinical data were collected from 64 ARDS and 66 high-risk ARDS patients in Department of Respiratory Diseases of Xinqiao Hospital from January 2013 to March 2016.They included patients' demographic data,Acute Physiology and Chronic Health Evaluation system Ⅱ (APACHE Ⅱ) score,oxygenation index,blood routine test,coagulation function and inflammatory markers (procalcitonin,C-reaction protein,tumor necrosis factor and interleukin-6) within 24h and the state of survival or death of the 24th day.Risk factors for predicting progression of the high-risk ARDS patients into ARDS patients and influencing the prognosis of the ARDS patients were analyzed by using logistic regression.Results Univariate logistic regression analysis found that the independent risk factors for progression of ARDS were APACHE Ⅱ score (OR=6.764,P=0.001),hypoproteinemia (OR=10.54,P=0.002),white blood cell count (OR=3.912,P=0.012),fibrinogen (OR=9.953,P=0.064),and D-dimer (OR=4.239,P=0.029).The mortality rate was 43.75％ (36/64) in ARDS group,and the oxygenation index (OR=6.573,P=0.014),platelet count (OR=9.376,P=0.003),hypoproteinemia (OR=10.738,P=0.056) were the independent risk factors of death in ARDS patients.Multivariate logistic regression showed that combination of multiple indicators for predicting ARDS improved the specificity,but reduce the sensitivity.APACHE Ⅱ and hypoproteinemia (sensitivity 62.50％,specificity 92.42％) and APACHE Ⅱ and D dimmer (sensitivity 62.07％,specificity 93.33％) had better specificity and sensitivity.The specificity and sensitivity of combining hypoproteinemia and platelet count to predict the risk of death in these patients were 77.78％ and 60.71％.Conclusions In high-risk ARDS patients,combining hypoproteinemia or APACHE Ⅱ score with D-dimer to judge the development of ARDS has good specificity but poor sensitivity.For ARDS patients,low oxygenation index,thrombocytopenia and hypoproteinemia indicate a poor prognosis.

Borneol is a traditional Chinese medicine. In the past few years, many studies showed that borneol can improve the bioavailability of other drugs, promoting drugs to cross the blood-brain barrier, so the potential drug interactions between borneol and other medicines have attracted great attention, but the influence of borneol to CYP450 and its isoforms are rarely reported. In this research, male Wistar rats were orally administered by borneol for 7 days, then the mRNA and protein expression and the activities of CYP2D were detected, we also compared the pharmacokinetic parameters of CYP2D's specific substrate between control group and borneol group. The results show that borneol (33, 100 and 300 mg x kg(-1) x d(-1)) have no significant effect on CYP2D, while the activites of CYP2D increased 1.71, 1.97 and 2.89 times comparing to the control group. At the same time, borneol (300 mg x kg(-1) x d(-1)) caused the C(max) decreased 10.6% (P > 0.05), AUC(0-∞) decreased 27.5% (P < 0.01), CL/F increased 41.1% (P < 0.01), V(z)/F increased 23.1% (P > 0.05) of dextromethorphan. Our data provided that borneol speed up dextromethorphan's elimination in vivo. Since the activity of CYP2D can be induced by borneol, the metabolic interactions might happen when borneol and the substrate drug CYP2D are used together.

Background Pathologic myopia is one of the common blinding eye diseases.Recent research suggests that immune response participates in the pathogenesis of pathologic myopia,and inflammation is an important factor that influent immune status.Objective Present study was to observe the change of high sensitive C-reactive protein(hs-CRP) in serum in the patients with pathologic myopia and explore the role of inflammation in the development of pathologic myopia. Methods Serum hs-CRP was measured from 30 patients with pathologic myopia,30 patients with simple myopia and 30 normal controls with Nephelometric Turbidity in the OLYMPUS AU5400 automatic biochemical analyzer.Written informed consent was obmined from each subject before medical examination.Results The mean age was(30+10) years in pathologic myopia group,and(32+8)years in simple myopia group and(32+9)years in normal control group.The range of preoperative spherical equivalent refraction was (-6.00--22.00) D in pathologic myopia group,(-1.00--6.00) D in simple myopia group and(-1.00-+1.00) D in normal control group.The level of hs-CRP in serum was(3.68±1.15)mmol/L in the patients with pathologic myopia and was significantly higher than that of simple myopia group(1.99±0.68 mmol/L)and normal controls (2.11±O.66 mmol/L)(q=10.69,P＜0.01;q=9.91,P＜0.01),respectively.No significant correlation was found between hs-CRP level and myopic degrees in pathologic myopia group(R2=0.037,P＞0.05). Conclusion Hs-CRP may play rule in the inflammatory reaction during the pathogenesis of pathologic myopia.

Objective To detect the relationship of pathological grade and stage of bladder cancer with common chromosomal aberrations of urine exfoliated cells by FISH. Methods A total of 99 urine samples were detected by FISH with probes of chromosomes 3,7,17 and 9p21 to collect pathological grade and stage information of bladder tumor tissues. Results (1) The aberrations of chromosome 3 and 17 had significant correlation with pathological grade and stage (P<0.05) but that of chromosome 7 had no correlation with pathological stage (P>0.05), but had correlation with grade (P < 0.05). The aberration of 9p21 had no correlations with pathological grade or stage (P > 0.05). (2)The polysomic chromosomal aberrations of chromosomes 3, 7 and 17 assessed correlated with high-grade and high-stage bladder carcinoma. The 9p21 deletion was found at a significant frequency in low-grade and low-stage lesions, when, 9p21 amplification was found at a significant frequency in high-grade and high-stage lesions. Conclusions Aberrations of the four chromosomes, especially polysomic chromosomal aberrations of the bladder cancer cases could present a possible trend toward greater chromosome increased with tumor grades and progressive stages of invasion.

Objective To explore the toxicity and biological activity of cobalt nanoparticles (CoNPs) on osteoclasts,and to analyze the relationship between cobalt nanoparticles and osteolysis.Methods From November 2014 to July 2015,RAW264.7 cell was induced to osteoclast-like cell by LPS.Different concentrations of cobalt nanoparticles and cobalt chloride were added,and the cell morphology was observed under a microscope.24 h after induction on RAW264.7,cells were grouped into cobalt nanoparticles group (10,20,50,100 μmol/L),cobalt chloride group (10,20,50,100 mol/L) and control group.MTT assessment and Q-PCR were performed at 2 h,4 h,8 h,24 h,48 h post-treatment.Results With the increase of concentration (10,20,50,100 μmol/L) and the action time (2 h,4 h,8 h,24 h,48 h),the inhibition rate of cobalt nanoparticles and cobalt chloride on osteoclast like cells was significantly increased,and the inhibition rate of cobalt nanoparticles was higher.With different concentrations (10,20,50,100 μmol/L) of CoNPs and cobalt chloride,the relative expression of CAⅡ,Cat K gene mRNA expression decreased compared with the control group,when the concentration of CoNPs was in the range of 10-50 μ mol/L,the relative expression of CAⅡ and Cat K was increased,which was reduced in cobalt chloride group.Conclusion Different concentrations of cobalt nanoparticles and cobalt chloride can inhibit the proliferation and differentiation of osteoclasts,and cobalt nanoparticles is more pronounced,when the concentration of cobalt nanoparticles was 10-50 μmol/L,the relative expression of osteoclasts CAⅡ,Cat K increaseed,which was suppressed at the same concentration of cobalt chloride.

Objective To investigate the expression of CD40-CD154 co-stimulatory pathway in peripheral circulation and intestinal mucosa in patients with inflammatory bowel disease (IBD),the difference between the expression of CD40-CD154 in patients with IBD and that in healthy controls,and the correlation between CD40-CD154 levels and disease activity. Methods A total of 62 patients with Crohn's disease (CD),64 patients with ulcerative colitis (UC) and 56 healthy controls were enrolled. Enzyme-Linked Immuno Sorbent Assay (ELISA),SYBR-green real time PCR and immunohistochemical assay were respectively applied to evaluate expression of CD40-CD154 in plasma,mononuclear cells of peripheral blood and intestinal mucosa. Results Levels of CD40 (P=0. 000) and CD154 (P=0. 001) in plasma,mononuclear cells of peripheral blood and intestinal mucosa were significantly higher in patients with CD and UC than in healthy controls. However,no correlation between disease activity and CD40-CD154 expression in peripheral circulation or intestinal mucosa was detected (P ＞ 0. 05 ). Conclusion CD40-CD154 pathway activation is found in plasma,peripheral blood mononuclear cells and intestinal mucosa in patients with IBD,but is not correlated with disease activity.
