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 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.

Objective To compare the efficacy and safety of full-thickness peroral endoscopic myotomy (POEM) and circular myotomy for patients with severe achalasia.Methods The clinical data of 123 patients with severe achalasia who were admitted to the Second Xiangya Hospital of Central South University from August 2011 to May 2013 were retrospectively analyzed.Seventy patients who received full-thickness POEM were in the full-thickness myotomy group,and the other 53 patieuts who received circular myotomy were in the circular myotomy group.The clinical efficacies and incidences of complications of the 2 groups were compared.Patients in the 2 groups were followed up at the out-patient department till May 2014.The consecutive measurement data were presented by (x) ± s and analyzed using thc t test; the non-consecutive data were presented by M (range) and analyzed using the Wilcoxon rank test.Data before and after operation were compared using the repeated measure of analysis of variance.The count data were analyzed using the chi-square test.Results All the patients successfully received POEM.The operation time of the full-thickness myotomy group and the circular myotomy group were (57 ± 8)minutes and (63 ± 12)minutes,with significant difference between the 2 groups (t =3.421,P <0.05).The incidences of complications of the full-thickness myotomy group and the circular myotomy group were 14.3% (10/70) and 11.3% (6/53),with no significant difference between the 2 groups (x2=0.234,P >0.05).Atotal of 119 patients were followed up,with the median time of 18 months (range,12-24 months).The Eckardt scores at postoperative month 6 and 12 were 0 (range,0-3) and 0 (range,0-3) in the full-thickness myotomy group,and 0 (range,0-2) and 0 (range,0-3) in the circular myotomy group,with no significant difference between the 2 groups (Z =0.525,1.476,P > 0.05).The sussess rates of the full-thickness myotomy group and the circular myotomy group were 98.6% (69/70) and 98.1% (52/53),with no significant difference between the 2 groups (x2=0.040,P > 0.05).The diameters of the esophagus at postoperative month 6 of the full-thickness myotomy group and the circular myotomy group were (3.2 ± 0.3) cm and (3.4 ± 0.4) cm,with no significant difference between the 2 groups (t =1.927,P > 0.05).The diameters of the esophagus at postoperative month 6 and 12 were significantly lesser than (5.9 ± 1.0) cm and (5.9 ± 1.0) cm before operation (F =780.923,493.018,P < 0.05).No recurrence was detected in the 2 groups during the follow-up.Conclusion The short-term efficacy and incidence of complications of full-thickness myotomy and circular myotomy are comparable,while the operation time of patients who received full-thickness myotomy is shorter.
