Objective To analyze the clinical effect of debridement in the treatment of Kashin-Beck disease under an ankle arthroscopy.Methods Totally 40 patients with ankle Kashin-Beck disease who had underwent surgery in the Fifth Hospital of Daqing from January 2015 to October 2016 were selected as the research subjects.All patients were treated with cleaning treatment under arthroscopy,evaluated via the visual analogue scale method,and compared pain before and 6,12 month after the treatment.Walking function and ankle motion of the patients were evaluated via an ankle-scoring system,and the quality of life of patients was investigated before and after the treatment through a questionnaire survey.Results The visual analogue scale of before and 6,12 months after the treatment was (6.2 ± 1.0),(2.3 ± 1.2) and (1.6 ± 0.4) scores,respectively;ankle foot score (53.3 ± 6.8),(86.6 ± 5.1) and (88.7 ± 6.2) scores,respectively;ankle activity score (15.9 ± 4.1),(36.9 ± 4.9) and (41.8 ± 6.4) scores,respectively;and life quality score (53.1 ± 4.0),(75.4 ± 6.6) and (88.7 ± 10.5) scores,respectively.The differences between groups were statistically significant (F =2.1,2.6,2.3,2.5,P ＜ 0.05).Visual analogue scale of 6 and 12 months after the treatment was significantly lower than that before the treatment,ankle foot score and ankle activity score and life quality score were significantly higher than those before the treatment (P ＜ 0.05).Conclusion The debridement under an ankle arthroscopy can effectively reduce the pain of patients with Kashin-Beck disease,and improve the walking function of the patients obviously,significantly improve the patients' life quality,and the method should be widely applied in clinical treatment.

Objective To explore the incidence rate and related factors of high intraocular pressure after vitro-retinal surgery for patients with diabetic retinopathy(DRP). Methods The 986 patients(1 326 eyes) with DRP arranged vitro-retinal surgery were studied. The inci-dence rate of intraocular pressure was analyzed between different types,grades,complicated with macular detachment,filled with silicone oil/C3F8,total/supplementary retina photo-coagulation and crystalline lens excision. Results The incidence rate of high intraocular pressure was 27. 8%(368/1 326). The incidence rate of high intraocular pressure of proliferative DRP (34. 0%) was obviously higher than non-pro-liferative DRP (17. 2%)(χ2 =30. 648,P=0. 000),and higher in DRP D grade than B grade(34. 1%,20. 8%)(χ2=8. 834,P=0. 003). The incidence rate of high intraocular pressure of proliferative DRP (34. 0%) was obviously higher in patients complicated with macular de-tachment(30. 4%,22. 7%)(χ2 =8. 834,P=0. 0030). The incidence rate of patients filled with silicone oil/C3F8(39. 1%,24. 0%) (χ2 =28. 088,P=0. 000),total/supplementary retina photo-coagulation(32. 8%,16. 8%) (χ2 =21. 159,P=0. 000),with/without crystal-line lens excision (40. 5%,25. 9%)(χ2=15. 532,P=0. 0001)was different obviously. Conclusion There is a high incidence rate and re-lated factors of high intraocular pressure after vitro-retinal surgery for patients with diabetic retinopathy,and it is related to different DRP types,grades,complicated with macular detachment,filled with silicone oil/C3F8,total/supplementary retina photo-coagulation,crystalline lens excision.

Objective To study the clinic manifest-rations, mechanism, diagnosis and treatment of pulmonary arterial hypertention (PAH) in systemic lupus erythamatosus (SLE). Methods The clinic symptoms, laboratory tests. Doppler tests of patients who were diagnosed with PAH and SLE during last five years were analyze retrospectively. Results Anti-RNP antibody's prevalence rate was high. The presence of pulmonary arterial perssure (PAP) was not related to SLE disease active index (SLEDAI). Those who had PAP higher than 45 mm Hg were prone to have Raynaud's phenomenon PAH had no association to auto-antibodies and other systemic lesions. There were no differences in clinic features, auto-antibodies and other examinations between those with kidney injure and without kidney injure. Conclusion PAH may develop insidiously in SLE, so early diagnosis and prompt treatment of PAH can improve the prognosis.

Objective To investigate the effect of wire?reinforced epidural catheters on the success rate of epidural catheterization for labor analgesia. Methods A total of 200 nulliparous parturients who re?ceived labor analgesia voluntarily, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, aged 20-45 yr, with body mass index<35 kg∕m2, were divided into 2 groups (n=100 each) using a random number table: common catheter group ( group Ⅰ) and reinforced catheter group ( group Ⅱ) . After suc?cessful epidural puncture, the corresponding catheter was inserted inⅠandⅡgroups. The development of difficult insertion, intravascular catheter insertion or paresthesia during insertion was defined as a failure of epidural catheterization. The occurrence of the failure of epidural catheterization was recorded. Results Compared with group Ⅰ, the failure rate of epidural catheterization was significantly decreased in groupⅡ( P<0.05) . Conclusion Wire?reinforced epidural catheters can raise the success rate of epidural catheter?ization for labor analgesia.

The combined use of chemometrics and chemiluminescence (CL) measurements,with the aid of the stoppedflow mixing technique,developed a simple time-resolved CL method for the simultaneous determination of captopril (CPL) and hydrochlorothiazide (HCT).The stopped-flow technique in a continuous-flow system was employed in this work in order to emphasize the kinetic differences between the two analytes in cerium (Ⅳ)-rhodamine 6G CL system.After the flow was stopped,an initial rise of CL signal was observed for HCT standards,while a direct decay of CL signal was obtained for CPL standards.The mixed CL signal was monitored and recorded on the whole process of continuousflow/stopped-flow,and the obtained data were processed by the chemometric approach of artificial neural network.The relative prediction error (RPE) of CPL and HCT was 5.9％ and 8.7％,respectively.The recoveries of CPL and HCT in tablets were found to fall in the range between 95％ and 106％.The proposed method was successfully applied to the simultaneous determination of CPL and HCT in a compound pharmaceutical formulation.
