ABSTRACT
Objective To investigate and analyze the changes of serum interleukin-34(IL-34),rheumatoid factor(RF) and nuclear factor κB receptor activator ligand(RANKL) in patients with rheumatoid arthritis Its relationship with osteoporosis.Methods A total of 40 patients suffering from rheumatoid arthritis in the hospital between January 2016 and January 2017 were included in the study group,and 40 healthy subjects who underwent the same period of physical examination at the same time were enrolled as controls.By enzyme-linked immunosorbent assay(ELISA) were detected in 2 groups of serum IL-34 and RANKL levels were detected by latex agglutination assay of serum RF levels in 2 groups,and routine testing in patients with bone mineral density,erythrocyte sedimentation rate(ESR),C reactive protein(CRP) and anti CCP antibody.And the modified DAS28 score of disease activity of rheumatoid arthritis evaluation.Results The levels of serum IL-34,RF and RANKL in the study group were significantly higher than those in the control group(P＜0.05).The incidence of osteoporosis in the study group was significantly higher than that in the control group(P＜0.05).The levels of IL-34,RF and RANKL in the osteoporosis patients were significantly higher than those in the normal group(P＜0.05).The Spearman correlation analysis showed that the serum IL-34 levels were positively correlated with ESR,CRP,anti-CCP and DAS28 (P＜ 0.05).There was a negative correlation between serum IL-34,RF and RANKL levels and bone mineral density(P＜0.05).Conclusion The levels of serum IL-34,RF and RANKL in patients with rheumatoid arthritis were significantly increased,and the above indexes were negatively correlated with bone mineral density.It suggested that IL-34 may be involved in osteoporosis.
ABSTRACT
Objective To investigate the prognostic value of metabolic parameters of 18F-fluorodeoxyglucose positron emission tomography/computed tomography(FDG PET-CT)before radiotherapy in patients with esophageal cancer receiving radiotherapy. Methods We retrospectively analyzed the clinical data of 37 patients with stage Ⅱ-Ⅲ esophageal squamous cell carcinoma admitted to Anhui Provincial Hospital from 2010 to 2015,who underwent PET-CT scans within 4 weeks before radiotherapy. The following information was collected:age,sex,the location of primary lesion,clinical stage,and treatment regimen.The maximum standard uptake value(SUVmax), mean standard uptake value(SUVmean), metabolic tumor volume(MTV), PET tumor length(PTL),and total lesion glycolysis(TLG)were calculated. The optimal cut-off values of SUVmax, SUVmean,MTV,PTL,and TLG were determined by the receiver operating characteristic(ROC)curve. The Kaplan-Meier method was used to calculate survival rates,and the log-rank test was used for survival comparison and univariate prognostic analysis;the Cox model was used for multivariate prognostic analysis of significant variables. Results The area under the ROC curve suggested that MTV>TLG>PTL=0.713>0.679>0.670. The Kaplan-Meier survival analysis showed that patients had better survival time when MTV was less than 27.44 cm3,TLG was less than 166.2 g,and PTL was less than 36.74 mm(P<0.05).The Cox multivariate regression analysis showed that only MTV was an independent prognostic factor for radiotherapy in patients with esophageal cancer(P=0.000). Conclusions MTV, TLG and PTL have certain values in predicting the prognosis of patients with esophageal cancer before radiotherapy, and are helpful for selecting and adjust the clinical treatment regimen and improving the survival rate and prognosis.
