RESUMEN
Objective:To investigate the effect of baseline function movement assessment of ankylosing spondylitis (AS) on treatment outcomes.Methods:The clinical data of 90 patients with AS who met the medical insurance treatment for major disease in Chengdu were collected including clinical symptoms, functional movement screen (FMS) and ankylosing spondylitis disease activity score (ASDAS) after 24 weeks adalimumab treatment. They were divided into the non-treat-to-target group and the non-treat-to target group based on the ASDAS score, t-test or χ2 test was used to compare the differences between the two groups. Logistic regression model was used to analyze the influence of baseline FMS on the outcome of patients reaching the treatment target. Results:① The two groups were different in the FMS [(15.8±2.3) vs (12. 6±2.5), t=6.17, P<0.001], squat [(2.2±0.6) vs (1.7±0.5), t=3.57, P=0.001], hurdle spanning [(2.2±0.7) vs (1.8±0.6), t=2.11, P=0.038], straight lunge [(2.3±0.7) vs (1.7±0.5), t=4.23, P<0.001], shoulder flexibility [(2.5±0.6) vs (2.2±0.8), t=2.21, P=0.037], active straight leg raise [(2.1±0.6) vs (1.8±0.6), t=2.35, P=0.021], spinal stabilization pushups [(2.4±0.7) vs (1.8±0.8), t=3.76, P<0.001], body rotation stability [(2.2±0.7) vs (1.6±0.8), t=3.42, P=0.001] at baseline. ② The two groups were different in ASDAS score [(0.96±0.28) vs (2.19±0.52), t=14.69, P=0.000], FMS [(17.4±1.9) vs (12.7±2.8), t=9.77, P<0.001], deep squat [(2.6±0.5) vs (1.5±0.5), t=9.09, P<0.001], hurdle step [(2.2±0.6) vs (1.8±0.8), t=2.80, P=0.006], straight lunge [(2.6±0.6) vs (1.8±0.9), t=4.85, P<0.001], shoulder flexibility [(2.8±0.4) vs (2.5±0.5), t=2.10, P=0.038], active straight leg raise [(2.2±0.6) vs (1.9±0.8), t=2.46, P=0.016], spinal stability push-ups [(2.8±0.4) vs (1.6±0.7), t=10.36, P<0.001], and body rotation stability [(2.3±0.7) vs (1.6±0.8), t=4.76, P<0.001] at the end of the observation. ③ The cut-off value of the FMS for predicting whether AS patients meet the standard at baseline was 14.25 points (Sensitivity 0.733, specificity 0.800). ④ Logistic regression results showed that in the baseline, FMS series of action tests, squat [ OR (95% CI)=0.155 (0.035, 0.677), P=0.013], straight lunge [ OR (95% CI)=0.375 (0.148, 0.953), P=0.039], spinal stability push-ups [ OR(95% CI)=0.136(0.043, 0.436), P=0.001], and body rotation stability [ OR(95% CI)=0.308 (0.121, 0.780), P=0.013] were the influencing factors of the AS patient's treatment outcome ( P<0.05). Conclusion:The AS patients in the non-treat-to-target group have better FMS tests at baseline and at the end of the study than the non-treat-to-target group. Squats, straight lunges, remember stable push-ups, and body rotation stability are the influencing factors for the treatment outcomes of AS patients at baseline.
RESUMEN
ObjectiveTo investigate the correlation of the serum and synovial fluid interleukin (IL)-1β,IL-6,tumor necrosis factor(TNF)-α and bone marrow edema with osteoarthritis of the knee (KOA).MethodsThe clinical data of 331 KOA patients were included and all patients had knee MRI.Bone marrow edema were detected in 172 cases and 159 cases had non-bone marrow edema.The clinical symptoms,WOMAC score,and the serum and synovial fluid IL-1β,IL-6,TNF-α levels were compared using One-way ANOVA analysis and Spearman's correlation analysis.Results① The serum and synovial fluid IL-1β,IL-6,TNF-α in osteoarthritis was positively correlated(serum r=0.24,0.38,0.31; synovial fluid r=0.20,0.29,0.33 ; all P＜0.05) ; ② The serum and synovial fluid IL-6 and TNF-α levels of osteoarthritis with bone marrow edema were significantly higher than those of the osteoarthritis without bone marrow edema(serum F=8.139,7.172; synovial fluid F=9.201,7.001; all P＜0.05); ③ The serum and synovial fluid TNF-α,IL-6 levels was associated with osteoarthritis with bone marrow edema in volume (serum r,=0.27,0.26; synovial fluid rs=0.29,0.32; all P＜0.05) and severity(serum rs=0.29,0.27; synovial fluid rs=0.29,0.31; all P＜0.05); ④ The serum and synovial fluid IL-1β,IL-6,TNF-α of osteoarthritis with synovitis was significantly higher than that of osteoarthritis without synovitis group (group of bone edema:serum F=3.931,5.866,5.514; synovial fluid F=4.211,5.202,5.972; all P＜0.05.non-bone edema patients:serum F=3.513,3.114,7.112; synovial fluid F=3.722,3.965,8.891; all P＜0.05).ConclusionIL-1β,IL-6,TNF-α are elevated in osteoarthritis with synov-itis.IL-6 and TNF-α are elevated significantly in knee osteoarthritis with bone marrow edema in particular.

Objective To investigate the expression of the double-stranded RNA-dependent protein kinase (PKR) gene in the peripheral blood leukocyte of patients with systemic lupus erythematosus (SLE),and to evaluate the relationship between the gene expression and the disease activity.Methods The clinical data of 100 SLE patients,40 non-SLE patients with rheumatic diseases,and 40 normal controls were collected.Total RNA was extracted from the peripheral blood and then reverse transcribed into cDNA.Sybr green dye based real-time quantitative PCR method was used to compare the expression levels (indicated as 2-△Ct value) of PKR in the three groups.Results (1) The 2-△Ct value of PKR expression level in the SLE patients was (14.69 ± 7.62),which was significantly higher than those in the non-SLE patients (5.09 ±4.73,P =0.012) and normal controls (4.79 ± 3.49,P =0.005).(2) The 2-△Ct value of PKR expression level in the SLE patients with severe activity was (22.57 ±2.61),which was significantly higher than those in the SLE patients with mild activity and no activity(12.94±2.41,P =0.000 ;8.85 ± 2.17,P =0.000).(3) The 2 △Ct value of PKR expression level in the SLE patients with lupus nephritis was significantly higher than that in the SLE patients without lupus nephritis (16.85 ± 7.32 vs 8.35 ± 2.04,P =0.034).(4) The 2-△Ct value of PKR was correlated with the systemic lupus erythematosus index(SLEDAI) scores(r =0.32,P =0.000),WBC (r =0.46,P =0.000),Hb (r =-0.22,P =0.035),the quantitation of urine protein in 24 hours (r =0.21,P =0.000),HDL-C (r =0.21,P =0.022),and anti-RNP antibody (rs =-0.21,P =0.025).Conclusions The expression of PKR in the SLE patients is up-regulated,especially in those with severe activity.The expression level of PKR gene is associated with SLE disease activity.
RESUMEN
The growth-inhibiting and apoptosis-inducing effects of WW domain-containing oxidoreductase (WWOX)gene on ovarian cancer cell line A2780 were investigated.The full length cDNA of human WWOX gene was amplified from normal human ovary tissues.The correct cDNA of full length WWOX was subcloned into eukaryocytic expression vector pCMV.After introduction of WWOX gene into cancer cells with liposome,the WWOX mRNA and protein level in the cancer cells were detected by reverse transcription polymerase chain reaction(RT-PCR)and immunoblotting.The growth activities of cancer cells were detected by Trypan blue staining.The clone formation assayin soft agar was employed to observe the proliferation of the cancer cells.Apoptosis was examined by DNA ladder and acridine orange-ethidium bromide fluorescent staining.The results showed that 72 h after WWOX gene transfection,the WWOX expression was increased significantly(P<0.01).The growth of ovarian cancer cells was decreased by 16.41% to 38.49%(P<0.01).The clone formation abilities were reduced(P<0.01).Some cancer cells presented the characteristic morphological changes of apoptosis with obvious ladder bands on electrophoresis.The apoptosis rate was(20.7±6.0)%(P<0.01).It was concluded that over-expression of WWOX gene could induce apoptosis and inhibit the growth of ovarian cancer cells,which might be potentially useful in the gene therapy of ovarian cancers.
