Rheumatoid arthritis(RA) is an autoimmune disease(AID) characterized by arthrosynovitis.Cytokines are involved in the whole course of the disease.Such important cytokines as TNF-? and IL-1? play a key role in the proliferation of synovial cells and progression of inflammation,and,therefore,have been taken as clinical therapeutic targets for RA in the recent years.The blocking agent of TNF-? or IL-1? is effective for only a few patients and the increasing adverse events it causes,such as infection and malignancy,are arousing more and more concern.The abnormal expression and imbalance of interleukin-6(IL-6) are closely associated with RA.IL-6 is an important regulatory factor for the pathogenesis of RA,and the blocking agent may be applied to the treatment of the disease.

Purpose To investigate the correlation of CT features with peripheral blood eosinophil count and proportion in eosinophilic gastroenteritis (EG).Materials and Methods Seventeen cases of clinically confirmed EG were retrospectively analyzed.The lesions were observed based on CT findings,and the count and proportion of peripheral blood eosinophil were calculated.Results Among 17 cases of EG patients,2 cases had one lesion,the peripheral blood eosinophil count and proportion of which were (0.28±0.22)× 109/L and (4.85 ± 2.19)％,respectively;5 cases had two lesions,the eosinophil count and proportion of which were (3.19± 1.82)× 109/L,(37.04± 11.36)％,respectively;6 cases had three lesions,the eosinophil count and proportion of which were (3.93 ±2.37)× 109/L and (45.22±22.99)％,respectively;3 cases had four lesions,the eosinophil count and proportion of which were (6.48±0.34)× 109/L and (75.83± 9.33)％,respectively;1 case had seven lesions,the eosinophil count and proportion of which were 8.87× 109/L and 75.60％,respectively.Conclusion There is a certain correlation of the peripheral blood eosinophil count and proportion with EG lesions.When the count and proportion of peripheral blood eosinophil increase significantly,the range of lesions may become more extensive,which suggests the scope of endoscopy or imaging examinations should be expanded in clinical work.

Objective To investigate the relationship between IL-6-174C/G and-572C/G site gene polymorphism with nonvalvular atrial fibrillation(NVAF) as well as the national differences of interleukin-gene polymorphism between Kazak and Han nationality in Xinjiang region.Methods Seventy-nine Kazak patients of NVAF(Kazak NVAF group),78 Han patients with NVFA (Han NVAF group),75 Han cases of non-AF and 79 Kazak cases of non-AF were selected in Xinjiang region.The venous bloods were collected from extracting DNA.IL-6 gene-174G/C and-572C/G polymorphism in various groups were analyzed by adopting the PCR-RFLP technique.Results The allele frequency of IL-6-572G/C site G in the NVAF group was significantly higher than that in the control group(x2 =4.076,P＜0.05).The allele frequency of IL-6 gene-572 G/C site G had statistical difference between the NVAF group and the control group(OR=1.519,95 ％CI:I.087-2.122,P＜0.05),but the distribution difference between the Han and Kazak control groups had no statistical significance(P＞0.05);the advanced age ≥75 years old)(OR=6.468,95 ％CI:2.427-17.240) and left atrial dimension(OR =1.053,95 ％ CI:1.022-1.085) were the independent factors of AF occurrence;the left ventricular ejection fraction was a protective factor for preventing AF occurrence.The allele frequency of IL-6 gene 174G/C site C and G had no statistical difference among various groups(P＞0.05).Conclusion The allele of IL-6-572 G/C site G is a risk factor of genetic predisposition in NVAF.IL-6-174G/C site gene polymorphism has no relation with the susceptibility of AF.
