Objective To evaluate the efficacy of levonorgestrel-releasing intrauterine system(LNGIUS) in the treatment of endometriosis. Methods Fifty-three patients suffering from endometriosis were placed LNG-IUS in uterine cavity after menstruation. The efficacy 3,6,12 months after LNG-IUS placement was observed and compared. Results The scores of dysmenorrhea, deep dyspareunia, menstrual anus pain 3,6,12 months after LNG-IUS placement were lower than those before LNG-IUS placement (P ＜ 0.05 ).CA125 [(21.8±12.5) kU/L]and destradiol [(78.8±45.5)ng/L] 12 months after LNG-IUS placement were improved than those before LNG-IUS placement and 3,6 months after LNG-IUS placement [CA 125:(36.3±17.5), (33.5±15.6), (28.2 ± 11.7) kU/L,destradiol: (40.4 ± 28.6), (42.5 ± 31.5), (56.5 ± 36.2) ng/L](P ＜ 0.05 ). The menstrual blood volume was less 6,12 months after LNG-IUS placement than that before LNG-IUS placement (P＜0.05), and the quality of life was improved( P ＜ 0.05 ). Conclusion LNG-IUS can be safe and effective treatment of patients with endometriosis, and less side effects.

Objective To evaluate the clinical effect of the procedure that involves drilling and inserting a motility peg at the time of hydroxyapatite orbital implant.Methods 89 patients who needed hydroxyapatite orbital implant were divided into groups A and B.The patients in group A were drilled and inserted a motility titanium peg when hydroxyapatite implantation.The patients in group B were drilled and inserted a motility titanium peg 6 months after hydroxyapatite implantation.Data were recorded.including the rate of postoperative pain and conjunctive edema,postoperative facial appearance,motility of the artifieial eye,the rate of hydroxyapatite exposure,excursion and extrusion of titanium peg and other complications.Results The mobility of the prosthesis was 44.97%in group A,and 45.34%in group B.There was no difference in appearance and the motility of their artificial eye between the two groups.The rate of excursion of titanium peg was 4.2% in group A and 7.3%in group B and no statistical difference was found between the two groups.There were no prosthesis exposure,extrusion of titanium peg,secondary infeetion and other complication in one-year follow-up.There were no difference in the rate of postoperative pain and eonjunctive edema in first operative stage.The postoperative reaction in group A was lighter than that in group B in secondary operanve stage.Conclusion The hydroxyapatite orbital implant primary procedure drilling is simple,safe,convenient and effective.It is worth to recommend that procedure that involves drilling and inserting a motility peg at the time of hydroxyapatite orbitaI primary implant.

Objective To evaluate the application of the polymethyl methacrylate (PMMA) artificial eye in acquired ophthalmostewesis. Methods We summarized the experience in the application of PMMA in prosthesis for 8 years. 1155 patients were involved in the artificial eye custom-made program. The artificial eye was individually prepared based on the patient's condition and characters of the healthy eye.Results PMMA artificial eye associated with hydroxyl apatite implantation gave good cosmetic results with good motility, and there was no rejective reaction. The artificial eye was almost same to the real one in color and transparency. Conclusion It is suggested that PMMA is one of the best materials for manufacture of artificial eye at present.

Objective To compare the clinical application of FACS analysis indicators and traditional infection indicators in early diagnosis of infection in premature infants .Methods 60 premature infants were divided into the infected group (n=29) and non-in-fected group(n=31) according to their clinical symptoms and laboratory results .BD FACSCanto Flow Cytometry was employed to detect CD11b ,CD64 and CD45RO ,BACTEC 9120 Automated Blood Culture System was used to conduct body fluids and secretions culture .Sysmex XE-5000 Automated Hematology Analyzers and i-CHROMA Reader Immunofluorescence Analyzer were adopted to conduct the complete blood count test and hypersensitive C-reactive protein (hs-CRP) detection ,respectively .Receiver operator characteristic(ROC) curve was used to analyze the diagnostic value of indexes above in preterm infants with infection ,and their sen-sitivity ,specificity ,positive predictive value and negative predictive value were calculated .Results On the first day after birth ,neu-trophil CD11b ,CD64 ,monocyte CD64 and hs-CRP levels of preterm infants in infection group were obviously higher than those in non-infection group(P<0 .05) .Differences of CD45RO ,WBC ,neutrophil absolute and percentage between the two groups showed no statistical significance(P>0 .05) .ROC area under the curve(AUC)>0 .7 was found in Neutrophil CD64 ,monocyte CD64 and hs-CRP ,which had higher value in early diagnosis of infection in premature infants .The highest sensitivity ,specificity ,positive pre-dictive value and negative predictive value were 79 .31% ,96 .78% ,83 .34% and 75 .00% ,respectively .Conclusion FACS analysis indicators has better clinical value in the early diagnosis of infection in premature infants .

Objective:To analyze the trend relevant factors leading to death and their patterns over a 10-year period in inpatients with connective tissue diseases (CTDs).Methods:All clinical data about death in inpatients with CTDs were retrospectively reviewed between 2005 and 2014 at the Department of Rheumatology and Immunology in Xiangya Hospital of Central South University.Results:In the 10-year time period,the overall hospital mortality was 15.689‰.The disease itself accounted for 44.71% of the total causes of death,infection accounted for 42.94%,and comorbidities accounted for 12.35%.The constituent ratio of deaths and the average hospital mortality caused by the disease itself declined gradually year by year,and the constituent ratio of deaths caused by infection and comorbidities increased gradually year by year (P<0.05).In 2013-2014,infection was the leading cause of death,which accounted for 51.06%.The survival time for CTDs inpatients with interstitial lung disease (ILD) was shorter than that of CTDs inpatients without ILD,and even the risk of death was 1.722 times of the latter.The proportion of deaths caused by the disease itself was the highest in systemic sclerosis and systemic lupus erythematosus,that by infection was the highest in idiopathic inflammatory myopathy (IIM),and that by comorbidities was the highest in rheumatoid arthritis.Conclusion:The proportion of deaths and the hospital mortality in CTDs inpatients caused by the disease itself show a declining trend,while the proportion of deaths caused by infection and comorbidities increase.CTDs patients with ILD have shorter survival time and an increase in risk of death.
