Objective To study the role of CT in the evaluation after patellar dislocation triple surgeries.Methods Retrospectively analysed the CT measurements of 60 recurrent patellar dislocation patients (61 knees),who had undergone patellar dislocation triple surgeries,within one month before and after procedures.The measurements included patellar tilt angle,lateral patellar displacement,trochlear con-gruence angle,Tibial Tuberosity-Trochlear Groove distance,Insall-Salvati Ratio and Caton-Deschamps Index.Moreover,the troch-lear dysplasia classifications of all patients were evaluated.In addtion,an analysis has also been completed for 40 (41 knees)of 60 patients who had second postoperative CT examinations as follow-up assessment 3 to 6 months after surgeries.Results All one-month postoperative measurements decreased obviously with statistical significance(P <0.05 ).Furthermore,one case of subluxa-tion,1 1 cases of abnormal Tibial Tuberosity-Trochlear Groove distance,13 cases of abnormal Insall-Salvati Ratio and 14 cases of Ca-ton-Deschamps Index abnormities were also observed.Besides that,it was also found that all patients had trochlear dysplasia and 5 cases were diagnosed with patellar subluxation or dislocation at the second postoperative follow-up assessment.Conclusion The patients with redislocation or risks for patellar instability can be detectecd by CT which provides objective evidence for postoperative evaluation and further treatments.

Objective To investigate the quality control and quality assurance of the SPECT/CT system.Methods The energy peak,energy resolution capacity and the intrinsic uniformity of the device's detector were regularly examined, and the quality control was performed. Results The daily hardware maintain could reduce the rate of system's trouble. The device's energy peak,energy resolution capacity were consistent during half year's observation period. The two detector's intrinsic uniformity were better after calibration than before. [ detector Ⅰ: ( 2.71 ± 0.28 ) vs (2.37±0.11)(t=2.489,P<0. 05);detector Ⅱ:(2.68 ±0.12)vs(2.38 ±0. 19)(t =6.421,P <0.01) ] .Conclusion Regular quality control and maintain could keep the function stabilization,enhance the availability rate of the SPECT/CT system.

Objective To investigate the role of thyroid autoimmunity in chronic urticaria. Methods The thyroid function, anti-thyroid auto-antibodies, and relevant cytokines were detected by RIA and ELISA methods in 56 patients with chronic urticaria and 40 healthy controls. Results Serum thyroid-stimulating hormone (TSH), anti-thyroglobulin antibody (TG-Ab) and anti-thyromicrosome antibody (TMA ) levels were increased in 8, 5 and 7 cases, respectively, in 56 patients, which were significantly higher than those in healthy controls (P

Further healthcare system reform calls for desirable pathway design. This paper introduced the logical framework of the new healthcare system reform pathway design and typical practical experience in Hangzhou.Known for " Internet+Smart healthcare" forerunner, Hangzhou has pioneered the reform of public hospitals and the construction of smart handy service for the public.With the aim of fully protecting the health rights and interests of urban and rural residents, comprehensive policy has been taken to deepen the reform of public hospitals; with the comprehensive promotion of contracted services and the primary level sharing of resources as a carrier, we will build a hierarchical medical service system of vertical linkage.We will also innovate and practice the governing philosophy of " Medicine has its limitations but we have the courage to overcome, service is boundaryless and we must pursue excellence".Promotion of party building in the industry also ranks high.Deepening the reform of " one visit for all" in the field of medical and health services as a measure to enhance people′s sense of gain; The " public-private partnership" to encourage the development of the social governance system and legalization in healthcare proves successful at this stage. However, there are still many challenges in the information security maintenance of smart healthcare, the balance of stakeholder interests in public hospitals, the all-round advancement of hierarchical medical service, standardizing and streamlining the reform of " one visit for all".
