Objective To explore the relation between rheumatoid arthritis (RA) and the meteorological factors.Methods All RA cases in the group were followed for 12 months,patients were follow-up for every two weeks.In each followed-up,all RA cases were evaluated by the disease activity score-28 (DAS28) and the improved Jamieson questionnaire,and the correlation of the DAS28 and the average values of meteorolo-gical factors (temperature,humidity,atmospheric pressure,relative humidity,wind speed) by Pearson correlation coefficient.The moderate-severe activity cases were evaluated by chi-square test of different seasons.Results One hundred and eighty-eight cases completed the observation,One hundred and sixty-four cases were in moderate disease activities (x2=9.42,P=0.022).Sixty-eight cases were distributed in winter,which was significantly higher than other three seasons.The average temperature and wind speed was negatively related to the DAS28 (r=-0.743,P＜0.01; r=-0.576,P=0.003).Conclusion The activity of RA has the characteristics of seasonal changes,and is easily being aggravated in winter.Many factors may influence RA,including temperature and wind speed.Creating an appropriate micro-climate environment is beneficial for RA patients to reduce the disease activity.

Objective To observe before and after surgery plasma vascular endothelial growth factor (VEGF) and transforming growth factor beta 1 (TGF-β1) content changes in the children with congenital heart disease(CHD) combined severe pulmonary arterial hypertension(PAH),and to explore the relationship with the pulmonary artery pressure.Methods Sixty cases patients with CHD in the First Hospital of Hebei Medical University from June 2014 to January 2015 were selected,including 30 cases left to right shunt CHD with severe PHD,30 cases no PHD.The content of serum VEGF,TGF-β1,parallel echocardiographic estimates pulmonary artery mean pressure(PAMP) of all children were detected with preoperative and postoperative 24 h,7 d and 30d.Results PAMP of children with severe PAH before surgery was (60.29±8.48) mmHg and (48.36±5.25)mmHg of postoperative 24 h,(28.21±3.29) mmHg of 7 d after surgery,(25.21±2.09) mmHg of 30 d after surgery,the difference was statistically significant (F within the grouP=39.86,P＜0.001),and compared with no PHD group,the difference was significant ((14.26±1.78) mmHg,(14.30±1.92) mmHg,(13.31±1.02)mmHg;F between groups=46.01,P＜0.001).The levels of VEGF and TGF-β1 in severe PHD group were (808.90±41.37) ng/L and (1156.96±83.68) ng/L of before operation,(620.21±30.30) ng/L and (906.20±65.11) ng/L of postoperative 24 h,(454.49±21.48) ng/L and (826.23±35.11) ng/L of postoperative 7 d,(454.49±21.48) ng/L and (806.49±29.48) ng/L of postoperative 30 d,the differences were significant (Fwithin the grouP=43.73,P＜0.001;F within the grouP=65.41,P＜0.001),compared with no PHD group,the differences were significant (VEGF:(379.25±20.21) ng/L,(380.05±19.98) ng/L,(380.05±19.98) ng/L,F between groups =54.09,P＜0.001;TGF-β1:(728.56±29.93) ng/L,(728.11±25.26) ng/L,(727.05±24.99) ng/L,F between groups=83.05,P＜0.001).Conclusion Plasma VEGF and TGF-β1 level has correlation with pulmonary artery pressure,the severity evaluation of pulmonary hypertension and surgical curative effect has a certain significance.After surgery,severe PAH is still exist in a certain period in children with pulmonary hypertension,sufficient attention should be paid to strengthening treatment and follow-up.

Background:CXC chemokine receptor type 2(CXCR2)is a member of G protein coupled receptor superfamily,and is mainly involved in the growth of tumor,angiogenesis and the pathogenesis of inflammatory diseases. Studies showed that CXCR2 was associated with the pathogenesis of inflammatory bowel disease(IBD),but the exact role has not yet been clarified. It was found that the interaction of interleukin-8(IL-8)with CXCR1 and CXCR2 played an important role in the pathogenesis of IBD. Aims:To investigate the expressions and significance of CXCR2 and IL-8 in patients with IBD. Methods:A total of 121 IBD patients in active stage from October 2013 to December 2014 at Zhongnan Hospital of Wuhan University were enrolled and assigned into Crohn’s disease(CD)group and ulcerative colitis(UC)group. Seventy healthy subjects were served as controls(HC). Expressions of IL-8 mRNA and CXCR2 mRNA in peripheral blood and intestinal mucosal tissue were determined by real-time PCR;expression of CXCR2 protein in intestinal mucosal tissue was determined by Western blotting. Results:In peripheral blood,expression of IL-8 mRNA in UC group was significantly higher than that in HC group(P = 0. 017),while expressions of CXCR2 mRNA in CD,UC and HC groups were not significantly different (P = 0. 285). In intestinal mucosal tissue,expressions of IL-8 mRNA in CD,UC and HC groups showed no significant difference(P = 0. 206),while expressions of CXCR2 mRNA in CD and UC groups were significantly higher than that in HC group(P = 0. 002;P < 0. 001),and expression of CXCR2 mRNA in UC group was significantly higher than that in CD group(P = 0. 005);expressions of CXCR2 protein in UC and CD groups were higher than that in HC group(P = 0. 049 P =0. 080). Conclusions:Expressions of CXCR2 mRNA and protein in intestinal mucosal tissue of patients with IBD, especially UC are significantly increased. Down regulation of CXCR2 expression in intestinal mucosa may provide a new target for treatment of UC. IL-8 is significantly highly expressed in peripheral blood of patients with UC,which suggests that IL-8 might be related mainly with UC.

BACKGROUND:Different weaving methods of autologous tendon lead to various treatment efficacies on cruciate ligament rupture, but the preferred method is stil controversial.
OBJECTIVE:To comparatively analyze the clinical efficacy of single-bundle and double-bundle autografts on anterior cruciate ligament reconstruction.
METHODS:A retrospective analysis of 48 cases of anterior cruciate ligament rupture was performed. According to the composition of graft beam, these 48 patients were divided into two groups:double-bundle group (n=24) and single-bundle group (n=24). Al surgical patients underwent autologous anterior cruciate ligament reconstruction by arthroscopy, and were fol owed up for at least 6 months. The function of knee joint after operation was comprehensively analyzed through IKDC and Lysholm scores.
RESULTS AND CONCLUSION:Al of the patients (n=48) exhibited no joint complications postoperatively, such as intra-articular infection, joint effusion and incision inflammation. The IKDC scores and Lysholm scores in the double-bundle group were better than those in the single-bundle group, but there was no statistical y significant difference (P>0.05). This study demonstrated that single-bundle and double-bundle autografts both have good curative effects on anterior cruciate ligament reconstruction by arthroscopy. But in contrast, the curative effects of double-bundle autografts are better.

Background:Studies showed that neuropeptide S receptor 1(NPSR1)gene polymorphisms were associated with the susceptibility of inflammatory bowel disease( IBD)in Europe’s populations,however,there is no study on the relevance in Chinese population. Aims:To investigate the association of NPSR1 gene polymorphisms with IBD in Chinese Han population. Methods:A total of 457 IBD patients[355 cases of ulcerative colitis(UC)and 102 cases of Crohn’s disease ( CD)]from Zhongnan Hospital of Wuhan University and 500 healthy controls were recruited. Genotyping of 2 single nucleotide polymorphisms(SNPs)of NPSR1,rs323922(C→G mutation)and rs740347(G→C mutation)was performed by using PCR and sequencing techniques. Results:Differences of the frequencies of genotypes and alleles for rs323922 and rs740347 between UC,CD patients and controls didn’t reach statistical significance(P >0. 05). Genotype-phenotype analysis showed that there were some impact of genotypes for rs323922 and rs740347 on clinical phenotypes of IBD:( i) For rs323922,mutant CG genotype was correlated with male CD patients(OR:0. 441,95% CI:0. 230-0. 844)and CD involving the colon(OR:0. 425,95% CI:0. 199-0. 911),and might be a protective factor.(ii)For rs740347,mutant CC genotype was correlated with early onset CD patients( <16 years old)(OR:15. 019,95% CI:2. 634-86. 470)and mutant C allele was correlated with CD involving the colon(OR:2. 142,95% CI:1. 709-4. 294),both were risk factors. Conclusions:Polymorphisms of NPSR1 rs323922 and rs740347 are not contributors of IBD susceptibility in Chinese Han population,but might be correlated with some clinical phenotypes of IBD.
