Objective To evaluate the specificity of Architect chemiluminescence immunoassay ( CLIA) for diagnosis of syphilis in the clinical screening test.Methods 65 774 syphilis specific antibody results in the Beijing Tongren Hospital were retrospectively analyzed.In this study, Architect CLIA for diagnosis of syphilis was used as a screening test for the pre-operative patients from August 2011 to July 2012.All the repeatedly reactive samples were tested by the tolulized red unheated serum test ( TRUST) and Treponema pallidum particle agglutination ( TPPA) assay.Samples with with discordant results were verified by western blot ( WB) Finally, all the results were statistically analyzed by software SPSS 17.0.Results Among 65 774 samples, 940 (1.43%) were found to be repeatedly reactive using the Architect CLIA.Of these sera, 330 ( 35.11%) were reactive and 610 ( 64.89%) were nonreactive by TRUST.Because a TRUST titer of 1:1was not always sufficient to confirm a TPPA reactive result, all the samples with CLIA reactive results were finally performed by TPPA assays.The results showed that 843 ( 89.68%) were positive and 97 (10.32%) were negative.After arbitrated by the WB, out of 97 TPPA negative sera, 18 (18.56%) were positive;7(7.22%) were indeterminate and 72(74.23%) were negative.Conclusions The specificity of Architect CLIA for diagnosis of syphilis was 99.89%.The results showed that confirmation by TPPA on sera with screening test for syphilis by Architect CLIA effectively decreased the false-positive results and could be suitable for a routine supplementary for syphilis.However, if necessary, the WB should be further utilized.

Objective To investigate the risk factors and incidence of gas-related complications in peroral endoscopic myotomy for easophageal achalasia.Methods Clinical data of 216 patients with achalasia treated by peroral endoscopic myotomy from August 2011 to November 2013 were collected.Potential risk factors for gas-related complications were analyzed by univariate and multivariate analysis.Results The incidence of gas-related complications was 10.2％ (22/216).Univariate analysis showed risk factors for complications were Sigmoid type esophagus,simple longitudinal incision for tunnel entry,tunnel width ≤3 cm,degree of myotomy,and operation time (P ＜ 0.05),while multivariate analysis showed the risk factors were Sigmoid type esophagus,simple longitudinal incision for tunnel entry,and tunnel width ≤3 cm(P ＜ 0.05).Conclusion Simple longitudinal incision for tunnel entry,tunnel width≤3 cm and sigmoid type esophagus are risk factors of gas-related complications in POEM,while myotomy depth is not.

Objective To explore the effects of multidisciplinary comprehensive pulmonary rehabilitation on aged patients with pneumo-coniosis. Methods From January, 2012 to January, 2015, 85 old stable inpatients with pneumoconiosis were divided into control group (n=40) and rehabilitation group (n=45). Both groups accepted routine medicine, while the rehabilitation group received multidisciplinary com-prehensive pulmonary rehabilitation for twelve weeks. They were assessed with cardiopulmonary exercise test, BODE index and quality of life before and after treatment. Results The maximum work, maximal oxygen uptake, 6-minute walk distance, scores of modified Version of the British Medical Researsh Council Respiratory Questionnaire, BODE index, activities of daily living, social activities, depression and anx-iety improved in the rehabilitation group after treatment (t>3.379, P<0.01), and were better than those in the control group (t>2.201, P<0.05). No imporvement was found in all the indices in the control group after treatment (t<2.339, P>0.05). Conclusion Multidisciplinary comprehensive pulmonary rehabilitation can effectively improve exercise tolerance and quality of life in aged patients with pneumoconiosis.

Purpose To analyze the relationships between glomerular filtration rate (GFR) measured by SPECT and renal parenchyma thickness and enhanced CT value measured by CT, and to explore predictive significance of CT in evaluating renal function of patients with hydronephrosis.Materials and Methods One hundred and fifteen patients diagnosed with unilateral hydronephrosis by ultrasound were retrospectively analyzed. GFR% (GFR percentage of affected kidney to the both kidneys) was measured by SPECT. CT% (percentage of affected renal parenchyma thickness to the both kidneys) and enhanced CT% (percentage of enhanced CT value of affected kidney to the both kidneys) were measured by pre- and post-contrast CT scan. According to GFR, the renal function was divided into mild-to-moderate impairment, severely impairment and non-function. Twenty-five volunteers were recruited as control group. CT%, enhanced CT% and GFR%among the four groups were compared, and the correlation of CT% and enhanced CT%with GFR% was analyzed to evaluated CT in predicting renal function.Results CT%, enhanced CT% and GFR% in mild-to-moderate impairment group was significantly greater than those in severely impairment group and non function group (F=20.24, 7.78 and 329.21,P<0.05). GFR% was positive correlated with CT% (r=0.58,P<0.05) and enhanced CT% (r=0.61,P<0.05). Area under curve (AUC) of CT% were 0.54, 0.79 and 0.83 for mild-to-moderate impairment, severely impairment and non-function, with sensitivity of 92.91%, 93.47%, 65.72%, and specificity of 35.33%, 59.47%, and 88.62%, respectively. AUC of enhanced CT% were 0.79, 0.89 and 0.96 for the three groups, with sensitivity of 97.51%, 80.02%, 97.66%, and specificity of 58.14%, 89.82% and 94.27%, respectively.Conclusion There was high correlation between renal function imaging by SPECT and CT in evaluating renal function of hydroneohrosis patients. Pre- and post-contrast CT scan can be used as complements in predicting renal function, and post-contrast CT with high accuracy.
