Objective To summarize our experience on the treatment for severe vascular injuries in the operation of great saphenous varicose vein. Methods The clinical data of 4 cases (5 lower limbs) from December 2004 to April 2009 of severe vascular injuries were retrospectively analyzed. For the lower limbs in which from the end of femoral artery to the upper part of posterior tibial artery were stripped, reconstruction operation using blood vessel prothesis was performed, above knee amputation was performed because of limb gangrene. For three limbs in which 10 cm to 15 cm superficial femoral artery were stripped, reconstruction operation using autologous saphenous vein were performed, above knee amputation was performed for one limb 5 days after the operation. For the limb in which 2 cm superficial femoral vein were cut, reconstruction operation using autologous saphenous vein were performed. Results No cases died perioperatively,for four limbs of injuried artery, ampution were performed for two limbs(50% ) ;two limbs (50%) were saved. The patient of injuried superficial femoral vein recovered. Conclusions Severe vascular injuries can be prevented and its incidence reduced by improving the awareness for iatrogenic vascular injuries,accurate operation; once the vascular injury occurred, prompt and rational measures must be adopted.

Objective To develop a scale of social adaptation degrees of special service personnel (referred to as scale) applying Traditional Chinese Medicine and psychological theory and to assess its reliability and validity. Methods By literature review, job analysis, inventory survey, topics interview, this scale was determined in dimensions, items and items pool based on theoretical model. Results After specialist important analysis and combining the different results of statistical analysis, including Cronbach's α coefficient, resolution factor, correlation analysis and confirmatory factor analysis, 6 dimensions, 14 factors and 40 items were finally kept in the scale. The dimensions were psychological characteristics, physical condition, intelligence level, interpersonal relationships, environmental factors and moral character. The factors were self-control, self-esteem character bias, self-confidence, physiological function, learning intelligence, creating intelligence, leadership intelligence, gregariousness, cooperative, confidence feeling, natural environment, social environment and moral character. Conclusion This scale was made on the basis of general international principle, it had good reliability and validity meeting measurement standard of traditional Chinese medicine and psychological theory, and it is an effective and practical evaluation tool of social adaptation degrees of special service personnel.

Objective To study the expression level of NLRP3 (NLR family, pyrin domain containing3) inflammasome (NLRP3, ASC, caspase-1 ) mRNA in peripheral blood monocytes (PBMCs) from patients with gout arthritis (GA) and to explore the pathogenesis of GA. Methods NLRP3 inflammasome mRNA was measured using quantitative real-time PCR in PBMCs. The expression of NLRP3 inflammasome mRNA in PBMCs was compared between patients with GA (n=24) and healthy controls (n=24). β-actin was selected as the internal control. Students' t-test was used in two independent samples and Spearman's correlation was used to evaluate the relationship between mRNA level and inflammatory parameters. Results The expression of ASC mRNA in GA increased significantly when compared to healthy controls [(0.029±0.021 ) vs (0.009±0.007 ), P＜0.01 ], and the expression of NLRP3 and caspase-1 mRNA was significantly lower in patients with GA compared to healthy controls [(0.062±0.084) vs (0.133±0.106), P＜0.05; (0.025±0.014) vs (0.117±0.156), P＜0.01]. Moreover, the expression of ASC mRNA was found to correlate significantly with globulin (r=-0.547, P＜0.05) and very low density lipoprotein cholesterol (r=-0.540, P＜0.05) in GA patients,and caspase-1 was correlated to globulin(r= -0.773. P＜0.01) and very low density lipoprotein cholesterol (r=-0.465. P＜0.05). Furthermore, the ASC mRNA in GA patients was associated significantly with NLRP3 mRNA(r=-0.450, P＜0.05) and caspase-1 (r=0.604, P＜0.01 ). Conclusion Dysregulated expression of the NLRP3inflammasome is involved in the inflammatory response and plays a key role in the pathogenesis of GA.

Though Runx2 and Osterix are both key transcription factors in the pathway of osteoblast differentiation, whether Runx2 positively regulates Osterix being unknown. It was showed that Runx2 induced the gene expression of Osterix both in the non-osteoblastic cell lines, either pluripotent or differentiated, and in the osteoblastic cell lines. At the same time, the results also indicated that Runx2 up-regulated the activity of the 3.2 kb human Osterix promoter. Further experiments identified a highly conserved and functional Runx2 binding site "AGTGGTT" within the promoter. Thus the results support the hypothesis that Runx2 is involved in the regulation of the Osterix gene expression. Moreover, the transient transfection and dual-luciferase assay showed Osterix up-regulated the activity of the 2.3 kb type Ⅰ collagen promoter in the non-osteoblastic cells, but Runx2 did not. This difference implies that Osterix, the down stream transcription factor of Runx2 during osteoblast differentiation, is needed to stimulate the osteoblast-specific gene expression of type Ⅰ collagen.

The core protein (CP) of the classical swine fever virus (CSFV) is one of its structural proteins. Apart from forming the nucleocapsid to protect internal viral genomic RNA, this protein is involved in transcriptional regulation. Also, during viral infection, the CP is involved in interactions with many host proteins. In this review, we combine study of this protein with its disorders, structural/functional characteristics, as well as its interactions with the non-structural proteins NS3, NS5B and host proteins such as SUMO-1, UBC9, OS9 and IQGAP1. We also summarize the important part played by the CP in CSFV pathogenicity, virulence and replication of genomic RNA. We also provide guidelines for further studies in the CP of the CSFV.

Objective To investigate the single nucleotide polymorphisms(SNPs) rs3733591(C>T) of SLC2A9 gene in Chinese Han population, and to explore the association of this gene polymorphisms with gout susceptibility, tophi, serum uric acid levels, other clinical and laboratory data and the levels of SLC2A9 mRNA of peripheral blood mononuclear cells(PBMCs). Methods ① A total of 297 primary gout arthritis patients(GA) and 211 normal controls(NC) were enrolled into this study. The clinical and laboratory data of patients were collected. The genotypes and alleles frequencies were measured by using TaqMan ?SNP Geno-typing Assays and the possible association between gene polymorphism of SLC2A9 and gout was investigated by Chi-square test. The odds ratios(OR) and 95% confidence intervals(95%CI) were calculated. ② The lev-els of SLC2A9 mRNA on PBMCs of 86 gout patients(46 patients in remission) and controls were measured by real-time quantitative polymerase chain reaction (RT-qPCR). The nonparametric test was used to analyze the expression in different groups. Results The frequencies of genotypes and alleles of rs3733591(C>T) in gout patients were different from controls(P<0.05). The frequency of TT genotype was significantly lower than that in controls (P<0.05) and the relative risk of this genotype to develop gout was 0.647 (95%CI: 0.452-0.925). Moreover, the frequency of T allele in cases was much lower than in controls (60.9% vs 69.2%, χ2=7.324, P=0.007, OR=0.695), but the frequency of C allele was much higher(39.1% vs 30.8%, χ2=1.440, P=0.007, OR=1.440). Interestingly, the levels of SLC2A9 mRNA on PBMCs in gout patients who carried TC genotype of rs3733591 was higher than those who carried TT genotype(P<0.05). There was no difference in the expression of SLC2A9 mRNA on PBMCs among different genotype carriers of rs3733591 in controls (P>0.05). However, there was no significant difference in the distribution of genotypes and alleles between 30 tophaceous gout patients and 190 non-tophaceous gout patients(P>0.05). Conclusion Results of present study suggest the rs3733591(C>T) polymorphism of the SLC2A9 gene might be associated with gout development, but not with tophaceous gout. The C allele predisposes to gout, and TT genotype and T allele might protect Chinese Han population from developing gout. The rs3733591(C>T) polymorphism probably affects the susceptibility to gout by influencing the f expression of SLC2A9 mRNA susceptibility.

Objective This study is aimed to evaluate the association between the ABCG2 gene rs2231142 variant and gout using meta-analysis. Methods Related studies were identified by searching extensively in Chinese and foreign language databases such as Pubmed, EMBASE, Cochrane Library, CBMdisc databases and so on. The quality of included studies was assessed by using the Newcastle-Ottawa Scale (NOS). The odds ratio (OR) was calculated using a random-effects or fixed-effects model. A Q statistic was used to evaluate the heterogeneity, and Eggerˊs test and funnel plot were used to assess publication bias. Sub-group analyses on ethnicities and sex were also performed. Results A total of 10 studies, including 3 478 gout patients and 10,089 controls from 6 countries or regions, were included and identified for the current metaan-alysis. It was found that the A allele or AA genotype of the ABCG2 rs2231142 polymorphism had an increased risk for gout in the general population [A allele: OR=2.03, 95%CI (1.77, 2.34), P<0.01 and AA genotype: OR=3.01, 95%CI (2.34, 3.88), P<0.01, respectively]. Similar results were found in sub-group analyses of different gender and races. Conclusion Existing evidence indicate that rs2231142 polymorphism (the A allele and AA genotype) is associated with increased risk of gout.

Objective To investigate the role of adiponectin (ADP) and its receptors (ADR) in pati ents with primary gouty arthritis (GA).Methods Enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of plasma ADP in 88 GA and 80 healthy controls (NC).Real time quantitative polymerase chain reaction (RT-qPCR) was employed to study the expression of ADR1 and ADR2 mRNA in peripheral blood mononuclear cells (PBMCs).The biochemical indicator of TG,HDL,LDL,VLDL,apoA1,apoB100 and uric acid (UA) were detected at the same time.T test,Spearman's correlations and regression analysis were used for statistical analysis.Results The concentration of plasma ADP was significantly lower in GA than that in NC [(6±7) μg/ml,(8±6) μg/ml,t=-3.71,P＜0.01 ],the expression of ADR1 and ADR2 mRNA in GA (ADR1:0.09±0.08,ADR2:0.0122±0.0164) was significantly increased when compared to the NC (ADR1:0.05±0.03,ADR2:0.0054±0.0024) (t=2.71,2.35,P＜0.05).In the GA patients,the level of ADP was negatively correlated with the lymphocytes count (LY) and UA (r=-0.32,-0.36,P＜0.05),and it was positively correlated with ESR and LDL level (r=0.31,0.39,P＜0.05).The expression of ADR1 mRNAwas negatively correlated with TG (r=-0.43,P＜0.05 ),but positivdy correlated with ESR and CRP level (r=0.45,0.57,P＜0.05).The expression of ADR2 mRNA was negatively correlated with glucose and UA(r=-0.50,-0.59,P＜0.05).Conclusion Altered expression of ADP and its receptors may be involved in thepathogenesis of gouty inflammation.
