Objective To investigate the effect of tunor necrosis factor alpha (TNF-α) antagonist treatment and traditional disease-modifying antirheumatic drugs treatment on the quality of life of male patients with ankylosing spondylitis (AS).Methods In 42 patients with AS open-label study,patients were grouped after consent,and divided into the TNF-α antagonist treatment group and the non-TNF-α antagonist treatment group.All patients were treated for 4 months.The clinical and laboratory indexes and quality of life changes were analyzed before and after the treatment.T test,Pearson's correlation analysis were used for statistical analysis with software version 13.0.Results There were no significant differences in age,disease course,disease activity and the quality of life between the two groups before treatment.Disease activity and the quality of life of the two groups after treatment were improved compared with that of before treatment.After treatment,the Bath ankylosing spondylitis disease activity index (BASDAI) score [(1.9±1.6) scores,(3.0±1.3) scores,t=-2.429,P=0.020],erythrocyte sedimentation rate (ESR) [(9±6) mm/1 h,(18±17) mm/1 h,t=-2.286,P=0.031] and C reactive protein(CRP) levels [(18±21) mg/L,(62±85) mg/L,t=-2.258,P=0.035] of the TNF-α antagonists treatment group decreased significantly than those non-TNF-α antagonist treatment group,while the hemoglobin (Hb) levels [(143±15) g/L,(138±18) g/L,t=2.545,P=0.015] were significantly increased in TNF-α antagonist treatment group.The improvement extent of quality of life was more evident in TNF-α antagonists treatment group,such as,the average score [(72± 15) scores,(55±19) scores,t =3.254,P=0.002].The average degree of improvement in quality of life and BASDAI score,Bath ankylosing spondylitis functional index (BASFI) score were negatively related to the improvement in the TNF-α treatment group (r=-0.497,P=0.018; r=-0.558,P=0.007).Conclusion TNF-α antagonist treatment can not only improve the AS disease activity,but can also improve the quality of sexual life of male patients,which may direct affect on male reproductive system.

Objective To explore the relationship between osteopontin (OPN),its downstream product thrombin-cleaved osteopontin (NTOPN) and radiographic changes in osteoarthritis (OA).Methods The levels of OPN and NTOPN in serum and synovial fluid were tested by enzyme-linked immuno sorbent assay (ELISA) kit in 22 OA patients and 21 health controls.The correlation between the above parameters and clinical data such as radiology changes of OA patients was analyzed.Results The serum level of OPN in the OA group was positively correlated with C reactive protein (CRP) (r =0.574,P =0.005).The serum level of OPN in the OA group was slightly lower than that in the healthy control group [(1.8 ± 0.5) μg/L vs (1.7 ± 1.1) μg/L,P ＞ 0.05].Similarly,the serum level of NTOPN in the OA group was significantly higher than that in control group [(21.1 ± 11.7) μg/L vs (14.7 ± 3.6) μg/L,P ＜ 0.05].Meanwhile,serum NTOPN level in female patients was significantly higher than that in male patients [(23.2 ± 11.80) μg/L vs (11.1 ± 4.9) μg/L,P ＜ 0.05].In synovial fluid of OA group,the level of OPN was (7.75 ± 2.33) μg/L,NTOPN was (0.91 ± 0.49) μg/L and the ratio of NTOPN/OPN was 0.12 ± 0.08.The level of OPN of synovial fluid in the OA group was positively correlated with CRP (r =0.574,P =0.005).NTOPN-to-OPN ratio of synovial fluid in the OA group was positively correlated with Kellgren-Lawrence grade (r =0.535,P =0.022).Conclusions The serum level of OPN is correlated with severity of inflammation in the OA patients.Meanwhile,NTOPN-to-OPN ratio of synovial fluid is correlated with OA severity.As a downstream bioactive product of OPN,NTOPN may play an important role in OA pathogenesis.Whether these parameters can be used as predictors of joint lesion severity and inflammatory status is worth further study.

Objective To identify the clinical features and risk factors of rheumatoid arthritis-associated interstitial lung disease (RA-ILD).Methods The clinical and laboratory data of 595 patients with RA hospitalized in Chaoyang Hospital.550 cases of patients were performed pulmonary high-resolution CT examination.Risk factors were analyzed with logystic regression analysis.Results ① There were 237 (39.8％)patients with RA-ILD.13.5％ of RA-ILD occurred before the dia-gnosis of RA,69.7％ of RA-ILD occurred within ten years after the diagnosis of RA,16.8％ of RA-ILD occurred more than ten years after the diagnosis of RA.② The most common manifestations of HRCT were reticular opacity (57.8％),pleural thickening (57％),ground-glass opacity (53.2％),followed by septal thicke-ning,nodules,bullae,cellular-like changes and bronchiectasis.③ Pleural disease,bronchiectasis,pulmonary hypertension in RA patients were associated with RA-ILD.④ Compared with the RA-N-ILD patients,RA-ILD patients had a higher proportion of male patients,higher rate of smoking,older mean age at onset,shorter duration,more swollen joints higher levels of lactate dehydrogenase,globulin,erythrocyte sedimentation,C-reactive protein and rheumatoid factor,the difference was statistically significant (P＜0.05).The forced vital capacity,forced expiratory volume in one second,carbon monoxide diffusion rate was lower,the difference was statistically significant (P＜0.05).Logistic regression analysis showed that age,smoking,elevated lactate dehydrogenase,RF-positive rate were relevant factors of RA-ILD.Conclusion ILD is common in RA,and most of it occurrs within ten years after the diagnosis of RA,and often coexists with other lung disease.Age,smoking,elevated lactate dehydrogenase,RF-positive rate

Objective:To optimize the determination technology for the total amino acids in Runing pills. Methods:The process was optimized by L9 (34 ) orthogonal design using the hydrolysis temperature, hydrolysis time and hydrochloric acid concentration as the evaluation factors,and the content and yield of total amino acids as the evaluation indices. Results: The optimal determination condi-tions were as follows:the hydrolysis temperature was 110℃, the hydrolysis time was 22 h and the hydrochloric acid concentration was 6 mol·L-1 . Conclusion:The optimal determination technology can be applied in the total amino acids from Runing pills,which pro-vides the basis for the further research of Runing pills.

Objective To study the clinical value of anti-ribosomal P0 protein antibodies (anti-P0). Methods Line immuno-assay and immunoblotting methods were used to detect anti-P0 and rRNP antibodies of 49 SEE patients and 61 patients with other rheumatic diseases.The expressions of anti-P0 were compared with those of rRNP antibodies.Possible relations between anti-P0 and clinical features and other antibodies in SLE were explored.Results 36.7%and 6.1% of SEE patients showed positive anti-P0 and rRNP antibodies respectively.Anti-P0 was always negative in patients with other rheumatic diseases (P＜0.01).Among SLE pa tients,incidence of skin rash was 77.8%(35.5%) ff anti-P0 was found to be positive (negative) (P＜0.05). Besides,for patients with positive and negative anti-P0,the chance of positive anti-SmD1 was 61.1% and 19.4% respectively (P＜0.01).Sensitiviy of anti-P0 for SLE diagnosis was 36.73% with specificity and positive predictive value as high as 100%,and 66.30% as the negative predictive value.Conclusion Sera anti-P0 is highly specific for SLE and it is associated with the occurence of rash and the expression of anti-StuD 1 anti bodies in SEE.

Objective:To study the impact of rotary cell culture system(RCCS) on the quality and activity of fetal islets of pancreas after cryopreservation and resuscitation.Methods:The fetal islets of pancreas were assigned into three groups averagely,experiment group 1,2 and control group.In experiment group1 and 2,fetal islets of pancreas were cultivated in RCCS and common culture respectively.While in control group,fresh fetal islets of pancreas were cultivated in RCCS all the time.We resected the fetal pancreas and digested with Collagenase V and purified with ficoll solution.Then standard cryopreservation step was adopted,and after resuscitation,the islets of pancreas were cultivated continuously.And the quantity,quality and activity of the islets of pancreas,and insulin stimulation test results in all groups were detected.Results:After purification,islets got from one fetal pancreas reached 2,331.98-5,115.43 IEQ(average 3,551.27? 253.76 IEQ) .The survival rate,the insulin release and stimulation index in islets of pancreas of group 1 incubated in RCCS were higher than those in common culture.Conclusion:RCCS are good for the growth and proliferation of islets of pancreas,and the islets of pancreas cultivated in RCCS have better insulin secreting capacity.RCCS combined standard cryopreservation method may further improve the cryopreservation effect.
