OBJECTIVE:To compare the effects of iguratimod combined with methotrexate and diacerein respectively on relat-ed indexes of refractory rheumatoid arthritis (RRA). METHODS:98 RRA patients were randomly divided into control group (48 cases)and observation group(50 cases). Control group received Iguratimod tablet 25 mg,twice a day+Methotrexate tablet with ini-tial dose of 10 mg,once a week,increased to 12.5 mg after 2 weeks,increased to 15 mg in the second courses,once a week. Ob-servation group received Iguratimod tablet(the same dosage and usage with control group)+Diacerein granule 50 mg,twice a day. 4-week was a course,they were treated for 6 courses. Morning stiffness time,the numbers of 28 joints tenderness and swelling,28 joint disease activity score (DAS28),erythrocyte sedimentation rate (ESR),rheumatoid factor (RF),IL-1,vascular endothelial growth factor (VEGF),tumor necrosis factor (TNF)-α,C-reaction protein (CRP),malondialdehyde (MDA),superoxide dis-mutase(SOD),total antioxidant capacity(TAOC),early peak flow(peak E),left ventricular late flow peak flow(peak A),E/A and left ventricular ejection fraction(LVEF)before and after treatment,and the incidence of adverse reactions in 2 groups were ob-served. RESULTS:Before treatment,morning stiffness time,the numbers of 28 joints tenderness and swelling,DAS28 score, ESR,RF,IL-1,TNF-α,CRP,VEGF,MDA,TAOC and peak A in 2 groups were significantly lower than before treatment,and observation group was significantly lower than control group;SOD,peak E,E/A and LVEF in 2 groups were significantly higher than before treatment,and observation group was significantly higher than control group,with statistical significances (P<0.05). And there was no significant difference in the incidence of adverse reactions (P>0.05). CONCLUSIONS:Iguratimod combined with diacerein is superior to iguratimod combined with methotrexate in improving cardiac function,oxidation-antioxidant imbalance play and reducing inflammatory reactions in the treatment of RRA,with similar safety.

Objective To explore airway remodeling and air trapping in asthmatic patients with low dose CT scanning and quantitative analysis. Methods 52 stable asthmatic patients in which 29 were severe and 23 were slight,and 20 healthy control cases were underwent low dose dual phase CT scanning. The LA/BSA, WA/BSA, TA/BSA, WA%and Pi10WA were analyzed as airway remolding indexes. The MLD of expiratory, VI-850 (%) of expiratory, MLD E/I, VI-850E-I (%) and VI-850/-950E-I (%) were analyzed as air-trapping indexes. One-Way ANOVA or H Kruskal-Wallis was used to analyze the above indicators. Results Airway remodeling indexes and LA/BSA were (9.6 ± 2.6), (11.0 ± 3.4) and (12.6 ± 3.0)mm2/m2 in severe asthmatics group, non-severe asthmatics group and healthy control group respectively, and there was significant difference between the three groups (F=5.60, P=0.006). WA%of each group was (65.1 ± 2.5)%, (63.3 ± 4.4)%and (62.0 ± 3.0)%, and there was significant difference between the three groups (F=5.53,P=0.006). The Pi10WA was (18.4±2.6), (17.7±3.1) and (16.4±1.4) mm2 respectively with significant difference between the three groups (F=3.59 ,P=0.033). Air-trapping indexes, MLD of expiratory of each group was-(771 ± 59),-(724 ± 43) and-(676 ± 60) HU respectively with significant difference (F=5.60, P=0.006). VI-850(%) of expiratory of each group was 30.79(30.45)%, 13.53(12.09)%and 2.85(6.87)%respectively with significant difference (H=17.20,P<0.001). Conclusions Low dose of CT scan and quantitative analysis can provide an objective and quantitative information for patients with airway disease of asthma, and both WA% and Pi10WA were objective indexes. The severe asthmatic patients were associated with obvious airway remodeling and air trapping compared with non-severe asthmatic patients.

Objective To investigate the significance of test of receptor activator of nuclear factor?kappa B(NF?κB)ligand(RANKL)in serum and urine for the diagnosis of osteoporosis. Methods A total of 53 patients with osteoporosis(the experimental group)and 45 healthy controls(the normal control group)were recruited in this study. The expression levels of RANKL in serum and urine was measured and compared by enzyme?linked immunosorbent assay. Results The serum and urine levels of RANKL in the experimental group were significantly higher than those in the normal control group(P<0.01). The areas under receiver operating characteristic(ROC)curve of serum and urine RANKL were 0.898 and 0.734, respectively. The combined detection of serum and urine RANKL and Ca2+reached a high sensitivity of 89.5%and a specificity of 86.1%for diagno?sis of osteoporosis. Conclusion RANKL may be closely associated with the progression of osteoporosis. Serum and urine RANKL test may be help?ful in the diagnosis of osteoporosis.

Purpose To explore the CT manifestations and pathological features of pneumonia-type lung cancer, and to improve the diagnosis capability of pneumonia-type lung cancer. Materials and Methods CT and pathologic features of 33 cases of biopsy or surgical pathology confirmed pneumonia-type lung cancer patients were retrospectively analyzed and classified according to the new pulmonary adenocarcinoma classification. Results Among the 33 pneumonia-type lung cancer subjects, CT showed multiple distributions within both lungs in 22 cases, lateral lobe distribution in 9 cases, segmental distribution in 2 cases. Lung consolidation was found in all lesions, among them 21 cases appeared mainly as lower lobe consolidation, 32 cases as inflatable bronchial symptoms within the consolidation, including inflatable bronchoconstriction in 24 cases;consolidation with multiple pulmonary nodules found in 23 cases;ground glass shadowing around or distal to the consolidation found in 26 cases;combined with cysts or honeycomb lung symptom in 13 cases. Inhomogeneous mild enhancement of lung consolidation after enhancement found in 18 cases and inhomogeneous moderate enhancement in 15 cases;blood vessel branch shadow within the consolidation was visible in 21 cases. Pathology results revealed 26 cases of invasive mucinous adenocarcinoma, and 7 cases of invasive mucinous adenocarcinoma partial mixed with papillary or alveolar adenocarcinoma. Conclusion CT features of pneumonia-type lung cancer are single or multiple opacities, within which inflatable bronchial symptoms can be observed, with multiple nodules and ground glass shadowing, cysts or honeycomb symptom can also be found concomitant, the lesions expand, increase and spread to both lungs, taking its dynamic change features into consideration will also help to improve the diagnostic accuracy.

Purpose To investigate the value of three-dimensional quantitative measurement of spiral CT in evaluating tumor size and preoperative T stage in stage I non-small cell lung cancer (NSCLC). Materials and Methods The complete data of 125 patients with stage I NSCLC confirmed surgically and pathologically were compared in terms of maximum tumor diameter and T stage analysis by means of three-dimensional quantitative CT measurement, two-dimensional measurement and general pathology measurement. Results The mean maximum tumor diameter of these 125 patients measured by quantitative three-dimensional CT measurement, two-dimensional measurement and general pathology measurement were (26.21±8.14) mm, (27.03±9.90) mm and (25.60±9.31) mm, respectively. The difference in mean maximum tumor diameter by two-dimensional measurement and three-dimensional quantitative measurement was significant, and remained so when two-dimensional measurement and pathology measurement was compared (t=2.377, P<0.05;t=2.961, P<0.01), but that between three-dimensional quantitative measurement and pathology measurement was not significant (t=1.281, P>0.05). Bland-Altman analysis showed that three-dimensional quantitative measurement had higher consistency than two-dimensional measurement when compared with the gold standard pathology measurement. When three-dimensional quantitative measurement was taken to be the staging criterion, 20% results (25 cases) obtained by two-dimensional measurement proved to be inconsistent. Conclusion Compared with two-dimensional measurement, quantitative three-dimensional CT measurement can provide more accurate information in maximum tumor diameter and T stage for patients with stage I NSCLC, therefore can be applied as a more accurate criterion in preoperative staging and prognosis of stage I NSCLC.
