Objective To evaluate the clinical application value of anti cyclic citrullinated peptide antibody(CCP) by immune tur‐bidity method for the the diagnosis of rheumatoid arthritis (RA) .Methods The serum of 195 cases of RA patients ,105 cases of os‐teoarthritis ,52 cases of osteoporosis ,42 cases of connective tissue ,40 patients with systemic lupus erythematosus ,305 cases of pa‐tients with other diseases and 90 cases of healthy controls were collected ,the CCP were detected by latex CMIA and ELISA . Results The CCP positive were 141 cases in RA(72 .30% ) ,54 cases(51 .42% ) in arthritis ,15 cases in osteoporosis (28 .84% ) ,15 cases in connective tissue(35 .71% ) ,18 cases (45 .0% ) in systemic lupus erythematosus (SLE) ,11 cases (3 .60% ) in other disea‐ses .There were negative in 90 cases of healthy controls .The variation coefficient was 1 .9% -2 .0% ,and the total coefficient of var‐iation was 2 .0% -2 .1% .The linear range of Latex method was divided into 0 .8-100 U/mL .There were no diffrence in the sensi‐tivity and specificity of detection to CCP by CMIA ,ELISA and Latex .Conclusion The sensitivity and specificity of detection to CCP by Latex was good ,and there was wide linear range .

Objective To investigate the efficacy and prognostic factors in patients with stage Ⅰ b and Ⅱ a cervical carcinoma by radical radiotherapy.Methods Between January 1999 and January 2012,108 patients with stage Ⅰ b and Ⅱ a cervical carcinoma received radical radiotherapy in Cancer Hospital,Chinese Academy of Medical Sciences were included and analyzed retrospectively.Patients of stage Ⅰ b1,Ⅰ b2,Ⅱa1 and Ⅱa2 were 18 (16.7％,18/108),38 (35.2％,38/108),33 (30.6％,33/108) and 19 (17.6％,19/108),respectively.Results The 5-year overall survival rate was 76.2％ and the 5-year disease free survival rate was 75.6％.Totally 25 (23.1％,25/108) patients developed recurrent disease,16 of them (64％,16/25) had local recurrences,6 (24％,6/25) had distant metastases and 3 cases had both local recurrence and distant metastases.Among patients with recurrent disease,23 died and 2 survive with tumor.Totally 24 patients died,23 of them died due to tumor recurrence and the other one died of other reason.The univariate analysis showed that,lymph node metastasis,squamous cell carcinoma antigen (SCC) levels before treatment,SCC levels after treatment 1 month had relation with overall survival time in patients with stage Ⅰ b and Ⅱ a cervical carcinoma (all P ＜ 0.05).The multivariate analysis showed that,lymph node metastasis and SCC levels after treatment 1 month were the independent prognostic factors for overall survival time for the cervical squamous cell carcinoma (OR =2.5,4.4 ; all P ＜ 0.05).Conclusions By means of radical radiotherapy,stage Ⅰ b and Ⅱ a cervical carcinoma patients with lymph node metastasis and SCC levels≥ 1.5 mg/L after treatment one month have poor prognosis.While,stage Ⅰ b and Ⅱ a patients with concurrent chemoradiotherapy after neoadjuvant chemotherapy did not affect the prognosis.The 5-year survival rate with concurrent chemoradiotherapy was higher than that of radiotherapy.
