BACKGROUND:Currently, discectomy, fusion or decompression is considered an effective and conventional method for the treatment of spinal disease. Although there have been many reports on the adverse effects of diabetes on spinal surgery, but there are stil some differences. OBJECTIVE:To systematical y evaluate the observational studies and case-control studies about the effect of diabetes on the complications of spinal surgery. METHODS:The control ed and comparative studies regarding the effect of diabetes on the results and complications of spinal surgery were searched from the database according to the inclusion criteria. The observed indicators including mortality, revision rate, surgical site infection, the incidence of venous thrombosis, blood loss, operative time and hospitalization time. Two authors participated in extracting the data and evaluating the methodology and quality of the included studies. Meta-analysis was conducted according to the guidelines of epidemiological observational studies (MOOSE). The risk assessment of the extracted data was conducted using RevMan 5.2 software. RESULTS AND CONCLUSION:Eighteen literatures, involving 2 824 063 patients, were eventual y enrol ed. The experimental result showed that the mortality, surgical site infection, incidence of venous thrombosis of diabetic patients after the spinal surgery were significantly higher than those of non-diabetic patients;the hospital stay was significantly longer than that of non-diabetic patients (P<0.05). There were no significant differences in the risk of revision, intraoperative blood loss and operation time between diabetic patients and non-diabetic patients (P>0.05). These results suggest that diabetic patients take a higher risk once accepting the spinal surgery than the non-diabetic patients. Diabetes increases the risks of postoperative mortality, surgical site infection, venous thrombosis and hospitalization time after spinal surgery.

Xanthine oxidase (XOD), catalyzing purine metabolism, is the key enzyme in uric acid (UA) biosynthesis, and becomes an important target for hyperuricemia treatment. The inhibition on XOD plays an important role in the treatment of hyperuricemia-related diseases, such as gout, as well as oxidative stress-induced tissue injury. Here, studies on the natural products with XOD inhibition are reviewed.

Objective To investigate the prevalence and charateristics of carotid atherosclerosis among healthy middle-aged people of community. Methods Totally 1930 subjects aged 50 years and above were selected randomly from 10027 participants recruited during Phase 3 of the Guangzhou Biobank Cohort Study (GBCS).Common carotid artery intima-media thickness (CCA-IMT) and carotid plaques (CP) were measured by B-mode ultrasonography using ALT HDI 3000 mainframe with a high-resolution. Results The prevalences of CCA-IMT and CP in men were higher than women [41.5％(400/963)vs.16.2 (157/967),34.1％ (328/967) vs.13.8％ (133/967),both P＜0.001].The prevalence of CCA-1MT was higher with age increasing in either men or women in groups of 50-yrs,60-yrs and 70-79 yrs (all P＜0.001).The most of CP was cankerous spot (37.8％),secondly hard spot (24.9％),soft spot (22.1％) and the prevalence of flat spot was lowest (15.2％).The number of CP was not significantly different between the left and right side (51.0％ and 49.0％).The most common location of CP was bifurcations of carotid arteries (61.7 ％),next the common carotid artery (21.0％) and internal carotid artery (ICA) was lowest (17.3 ％).The prevalence of CP was 44.4％ (83/87) in women aged 50- yrs,it was higher than that in men 20.9％ (108/517).However,the prevalence of CP was 79.1％ (409/517) in men aged more than 60 yrs,higher than that in women (55.6％). Conclusions The carotid atherosclerosis is commonly encountered disease in the male elderly,and the most of CP was cankerous spot in bifurcations of carotid arteries

Objective To explore the association of genetic polymorphism of fucosyltransferase (FUT) 2 and FUT3 and expression of Lewis antigen with ulcerative colitis (UC) in Chinese Zhejiang Han population.Methods We genotyped FUT2 (rs281377, rs1047781 and rs601338) and FUT3 (rs28362459, rs3745635 and rs3894326) in 485 UC patients and 580 healthy controls using SNaPshot. By immunohistochemistry method, we also evaluated expression of Lewis a and b antigens in the sigmoid colon of 10 UC patients and 10 patients with benign colonic polyps.Results The frequencies of mutant allele (A) and genotype (GA+AA) in FUT3 rs3745635 were higher in UC patients than in controls (P=0.016, 95%CI 1.339-1.699;P=0.038, 95%CI 1.330-1.742, respectively). Stratified analyses revealed that the frequencies of mutant allele (G) and genotype (TG+GG) of FUT3 rs28362459 were significantly lower in patients with extensive colitis than in those with distal colitis (P=0.001, 95%CI 0.567-0.786;P<0.001, 95%CI 0.503-0.742, respectively). Similar conclusions were drawn for the mutant allele (A) and genotype (GA+AA) of FUT3 rs3745635 in patients with extensive colitis compared to those with distal colitis (P=0.011, 95%CI 0.621-0.900;P=0.006, 95%CI 0.553-0.845, respectively). Although expression of Lewis b antigen in the sigmoid colon did not differ between UC patients and controls, Lewis a antigen expression was higher in the crypt epithelium of both inflammatory and non-inflammatory sigmoid colon of UC patients than in controls (P=0.028).Conclusion Polymorphisms of FUT3 and expression level of Lewis a antigen might be associated with UC.

Objective To investigate the effects ofthrce generations oftretinoids on the apoptosis of and caspase expressions in human cutaneous squamous cell carcinoma cell line SCL-1. Methods SCL-1 cells were cultured in vitro in the presence of three tretinoins, namely all-trans retinoic acid (ATRA), acitrefln and tazarotene at a concentration of 1×10-5 mol/L. On day 1, 3, 5, MTT assay and ELISA were used to detect the cell proliferation and apoptosis of these SCL-1 cells respectively; on day3, flow cytometry with Annexin V/PI was applied to analyze the cell cycle and early apoptosis, Western blot to measure the protein expressions of caspase-8 and caspase-9 in these cells. Results The growth of SCL-1 cells could be inhibited by ATRA, acitretin or tazarotene of 1×10-5 mol/L in a time-dependent manner (all P<0.01). All the three tretinoids could induce the cell apoptosis of SCL-1 cells (P<0.01), arrest them in G1-phase, and activate caspase-8 and caspase-9 (F=35.50, 25.79, respectively, both P<0.01). Of the three tretinoins, acitretin exerted the strongest effect on all the parameters tested. Conclusions Tretinoins can inhibit the growth and induce the apoptosis of cutaneous squamous carcinoma cells, which may be mediated through Fas- and mitochondria-way.

Objective To investigate the molecular transduction mechanisms of apoptosis in cuta-neous squamous cell carcinoma cell line SCL-1 induced by acitretin. Methods SCL-1 cells were cultured and continuously treated with various concentrations of acitretin. Apoptosis was assessed by enzyme-linked immunosorbent assay (ELISA) in these cells on day 1, 3 and 5. Apoptotic cells were observed by acridine orange staining on day 5. The protein expressions of Fas, FasL, Fas-associated death domain (FADD), cas-pase-8, caspase-3 and poly ADP-ribose polymerase (PARP) were examined using Western blot in SCL-1 cells treated with acitretin at 1 x 105 mol/L at different time points. Neutralizing anti-Fas antibody (ZB4,1 μg/mL) was utilized to pretreat SCL-1 cells before the treatment with acitretin, following that, ELISA was done to compare the apoptosis in cells treated with ZB4, acitretin, or the combination of ZB4 and acitretin,respectively. Results Acitretin induced the apoptosis of SCL-1 cells in a dose- and time-dependent manner.Morphologically, acitretin-treated SCL-1 cells showed a typical characteristic of apoptosis. Significant increase in Fas, FasL, and FADD protein expression, as well as the activation of caspase-8, caspase-3 and PARP were induced by the treatment with acitretin. The apoptosis absorbance value was 0.78 ± 0.04 in cells treated with acitretin alone, decreased to 0.41 ± 0.03 in cells treated with ZB4 and acitretin (P ＜ 0.05), .suggesting that ZB4 could block the apoptosis of SCL-1 cells inducedby acitretin. Conclusion Acitretin could induce the apoptosis of cutaneous squamous cell carcinoma cells likely by Fas signaling pathway.

OBJECTIVEThe aim of this investigation was to examine the changes of the color stability, surface microstructure and chemical constitution of light-curing composite resin after accelerated aging, and the relations between them.

METHODSFour light-curing composite resin were aged in an accelerated aging instrument. The color was measured by CIE L*a*b* with a spectrophotometer after treatment for 24 h and 96 h. And the color differences were calculated. Environmental scanning electron microscopy (ESEM) and Fourier transform infrared spectroscopy (FTIR) spectrometer were used to examine the microstructure and chemical composition of the specimens before and after accelerated aging. The color differences were analyzed statistically by repeated-measures two-way analysis of variance and t-test after aging for 24 h and 96 h. The level of significance was defined as alpha=0.05.

RESULTSThe materials demonstrated statistically significant differences in color after aging between the 24 h and 96 h (P<0.05). There were significant influences on the microstructure and the chemical composition after aging. The matrix appeared some concaves and pores, the filler particles exposed after aging. The energy of chemical bonds were weaken or broken under the aging, and the unsaturated polymer reacted again.

CONCLUSIONThe color differences of the composite resin increase with the aging time and irradiation dose. The hybrid filled composites have the best color stability.
