ABSTRACT
Objective To investigate the diagnostic and prognostic value of immunoglobulin (Ig)G isotype rheumatoid factors (IgG-RF) in rheumatoid arthritis (RA).Methods Five hundred patients with RA were enrolled randomly.IgG-RF antibody was detected by enzyme-linked immunosorbent assay (ELISA).The correlations between serum IgG-RF antibody and clinical features,disease activities,laboratory of RA patients were evaluated.The comparison of continuous variables was performed by using the Student t-test or Mann-Whitney U test in accordance with normality testing.Chi-square test was performed for categorical variables.A value of P less than 0.05 was considered statistically significant.Results ① IgG-RF was positive in 41.0％ (205/500) of RA patients.In patients with anti-citrullinated protein/peptide autoanti-bodies (ACPA) negative,RF negative or the seronegative patients (both ACPA and RF were negative),the positive rate of IgG-RF was 22.4％(24/107),13.2％(17/129) and 9.1％(5/55),respectively.② Compared with patients with negative IgG-RF,patients with positive IgG-RF had higher rates of joint deformity [(58.5％(120/205) vs 39.3％(116/295),x2=17.918] and bone erosion [(75.6％(118/156) vs 60.3％(140/232),x2=9.796] (P＜0.01,respectively).③ The patients with positive IgG-RF had higher rates of elevated ESR(86.3％ vs 67.8％,x2=22.426),IgG(29.9％ vs 20.0％,x2=6.310),compared to patients with negative IgG-RF (P＜0.05,respectively),and levels of ESR [(59±35) mm/1 h vs (47±32) mm/1 h,t=3.989] and CRP [(390±450) mg/L vs (290±340) mg/L,t=3.004] was higher in IgG-RF positive group than the negative (P＜0.01,respectivelys).④ Compared with the IgG-RF negative patients,the positive group had higher smoking rates (22.9％ vs 12.5％,x2=9.227),higher current smoking rates (16.6％ vs 7.1％,x2=11.119) and higher smoking index [(107±238) vs (49±161),t=3.199](P＜0.05,respectively).Conclusion IgG-RF had its clinical values in RA diagnosis.IgG-RF is significantly associated with joint deformity,bone erosions and smoking.
ABSTRACT
Objective To evaluate the value of 2012 classification criteria for early rheumatoid arthritis (ERA),2010 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) classification criteria,and 1987 ACR classification criteria in the diagnosis of early rheumatoid arthritis (RA).Methods Patients who had at least one swollen and tender joint with disease duration no more than 2 years,and age more than 16 years were enrolled.The patients were diagnosed as RA or other non-RA by 2 experienced rheumatologists.The clinical and laboratory parameters were recorded.The sensitivity and specificity of three RA classification criteria were compared by McNemar test,The areas under the receiver operating characteristic curve (ROC) curve (AUC) of each RA classification criteria were analyzed using MedCalc software.Results Atotal of 310 patients were enrolled in this study,including 182ERA and 128 non-RA.The sensitivity(88.5％) of ERA criteria was much higher than that of the 1987 ACR criteria (45.6％,x2=75.013,P＜0.05),and not significantly different with the 2010 ACR/EULAR criteria (91.8％,X2=1.042,P＞0.05).The specificity of ERA criteria (91.4％) of 2010 ACR/EULAR criteria (87.5％,x2=1.8,P＞0.05) was similar to that of the 1987 ACR criteria (96.1％,x2=3.1,P＞0.05).The AUC of ERA criteria was 0.962 [95％CI(0.934,0.980)],which was slightly better than that of the 2010 ACR/EULAR criteria 0.959 [95％CI(0.931,0.978)],Z=0.380,P=0.7038,and much higher than that of the 1987 ACR criteria 0.885 [95％CI (0.845,0.919)],Z=4.517,P＜0.01.Conclusion Overall evaluation,the diagnostic value of ERA criteria is better than 1987 ACR and 2010 ACR/EULAR criteria in early rheumatoid arthritis.Compared to 2010 ACR/EULAR classification criteria,ERA criteria is more simple and practical.
ABSTRACT
Objective To investigate the effectiveness of population rehabilitation in community and home-based aerobic exercise in reducing cancer-related fatigue and promoting the quality of life in postoperative elderly patients with esophageal cancer.Methods The 68 post-operative patients with esophageal cancer receiving the first chemotherapy in our hospital were assigned to two group (n=34,each):study group received an intervention of population rehabilitation of community,and control group received only home based aerobic exercise.The effect of intervention was evaluated by the Piper fatigue scale(PIPER) and he World Health Organization quality of life (WHOQOL-BREF) in the beginning of the next chemotherapy cycle.Results After 4 weeks intervention,the scores of PIPER and WHOQOL BREF were significantly lower in study group than in control group[(4.2±1.6) vs.(5.4±0.7),(45.3±10.0) vs.(49.9±10.7),t=-2.334,5.334,P=0.031,0.042)].The cancer related mild degree fatigue accounted for 23.5％ (8 cases) in study group which was significantly higher than in control group1case(2.9 ％,1 case) (x2 =11.865,P＜0.01).Conclusions The population rehabilitation in community is a safe and feasible intervention.It is superior to homebased aerobic exercise for alleviating the severity and extent of cancer-related fatigue in elderly patients.
ABSTRACT
Objective To investigate the status of life quality in the elderly in Shanxi Province Changzhi City, and to analyze its influencing factors. Methods The quality of life, activities of daily living and status of community services were measured simultaneously by 36-Item Short Form Health Survey (SF-36). Activities of Daily Living Scale, Community Healthy Needs Scale and survey results were used and analyzed using t-test, correlation and stepwise regression analysis. Results According to the criterion of life quality in the elderly which were proposed by Zhang Lei, the quality of life in the elderly scored 72. 1-117.0, reached 98.5%. The quality of life in the elderly was impacted by the ability of caring oneself, marital status, degree of culture, economic situation and so on. The demand rate for health guidance and periodic physical examination was higher. Conclusions The quality of life in the elderly is at a medium level. There is a wide gap between the demand of community healthy services and the utilization of community healthy services.
ABSTRACT
Objective To investigate the quality of life of elderly caregivers and its factors. Methods Elderly caregivers living in Changzhi City were enrolled in this study. 36-item short-form (SF-36) health survey and Activity of Daily Living Scale ( ADL) were used as study tools. The data was analyzed by statistical description,t test or multiple regression. Results Those with score of quality of life reaching 72. 1 to 117. 0 accounted for 98. 8%. The total score and score of eight dimensions of SF-36 showed statistically significant difference between different daily living activity groups ( P < 0.05) . The state of health and self-care ability of the elderly imposed a major impact on eight dimensions of SF-36. Age, sex, level of education, marital status and wage had different impact on each dimension of SF-36. Conclusion The quality of life of elderly caregivers is at a medium level. The main factors of quality of live of elderly caregiver are their state of health and self-care ability of the elderly.
ABSTRACT
Objective To explore the feasibility of Lugol's iodine staining in association with P53 oncoprotein test to detect early esophageal cancer and precancerous lesions through endoscopy. Methods Lugol's iodine was sprayed on esophageal mucosa under endoscopy in 78 patients with suspected early malignancy. Severe dysplasia which taken from unstained position by iodine were prepared immunohistochemically for P53 oncoprotein study. Then endoscopic mucosal resection (EMR) was performed to these severe dysplasia with P53 oncoprotein－ positive mucosa. Results There were 31 unstained areas (25 patients) including squamous cell carcinomas (n=3) and severe dysplasias (n=16). Expression of P53 was found in 7 severe dysplasia (43.8％ ),and 1 carcinoma in situ was found by EMR. Conclusion This modified method seemed feasible not only to detect early esophageal cancer,but also to resect severe dysplasia mucosa selectively by EMR.
