ABSTRACT
Objective To evaluate the accuracy of the biometry using immersion B scan and partial coherence interferometry (Lenstar LS900) for the axial length (AL) of silicone oil-filled eyes respectively.Methods Thirty-five silicone oil-filled eyes (38 patients) were included in the study.All of these eyes underwent silicone oil removal,cataract extraction and intraocular lenses implantation.The AL of all the silicone oil-filled eyes was measured with A/B-scan ultrasound and Lenstar LS900 before operation and with Lenstar LS900 after operation.The measured distance was compared respectively.The method of immersion B-scan guided with respective sonic velocity.AL was the sum of corneal thickness,anterior chamber depth,lens thickness,the apparent length of oil bubble (velocity values 996 m/s),the depth of the water layer beneath the oil bubble.Results Thirty-one eyes were measured with Lenstar LS900 before silicone oil removal,and the mean AL was (24.12± 1.70) mm,7 eyes failed to get the results before the operation;36 eyes were measured with Lenstar LS900 after silicone oil removal,and the mean AL was (24.45±1.89) mm.All eyes were measured with B-scan before silicone oil removal,and the mean AL was (24.87±2.52) mm.The difference (31 eyes) of AL measurement before silicone oil removal by two methods was (-0.00±0.09) mm;the difference (31 eyes) between pre-and post-surgical AL measurement with Lenstar LS900 was (0.02±0.07) mm;the difference (36 eyes) between pre-surgical AL measured with B-scan and post-surgical AL measured with Lenstar LS900 was (-0.02±0.11) mm.All the differences were not statistically significant (t=-0.205,1.752,-1.280;P＞ 0.05).The consistency of the results measured by two methods was well in Bland-Ahamn analysis.Conclusions Measurement results of AL between immersion B-scan guided with respective sonic velocity and Lenstar LS900 are high repeatability on silicone oil-filled eyes.The AL of silicone oil-filled eyes can be measured reliably by immersion B-scan guided with respective sonic velocity.
ABSTRACT
Objective To compare the applied signification of optical and ultrasonic biometry in observing the axial length of eyes with vitreous hemorrhage and retinal detachment. Methods This is a prospective clinical study. We randomly selected 57 cases (57 eyes) with vitreous hemorrhage and (or) retinal detachment from May 1, 2016 to May 31. Patients had not been performed eye surgery, also denied the history of ocular trauma and excluded other eye diseases. 25 eyes with vitreous hemorrhage, 24 eyes with retinal detachment, 8 eyes complicated with vitreous and retinal detachment hemorrhage. At 24 hours before surgery, we measured axial length using the Lenstar LS 900, immersion B-ultrasound (IB) and immersion A-ultrasound (IA). The differences between three methods were assessed with paired sample t-test. Results IB and IA data was collected from all 57 eyes, there was no statistical significance between measurements of IB and IA (P > 0.05). In the eyes with serious refractive medium opacity (36 eyes), the results showed no statistical significance difference between measurements of IB and IA (P > 0.05). The measurements of three groups can be obtained from the rest eyes (21 eyes): significant statistical difference of the measurements between IB and Lenstar was detected[(24.057±1.441)mm vs(23.470±1.775)mm],(t=3.099, P < 0.05) same results between IA and Lenstar was obtained [(23.962±1.443) mm vs (23.470±1.775) mm], difference was statistically significant (t=2.643, P < 0.05). But the measurements showed no statistical significance difference between the measurements of IB and IA (P > 0.05). Conclusions In the eyes with vitreous hemorrhage and (or) retinal detachment, the measurements of axial length could not be achieved or existed deviations on account of refractive medium opacity when using optical biometry. Under such circumstances, we should choose IA or IB as the optimization method to obtain measurements, in order to get much more accurate results.
ABSTRACT
Objective:To study the health equity and explore the influencing factors of health inequities among those insured in New Rural Cooperative Medical System and to provide theoretical and factual basis for improvement of medical insurance system through .Method:Using concentration index decomposition to explore the sources of inequity in health outcomes and the degree of horizontal inequity in health outcomes .Results:Economical level leads that the concentration indexes of two week prevalence favor the poor , i.e.the worse the health outcome of the rich is.Economical level leads that the concentration indexes of chronic disease prevalence and self -reported health defective rate favor the rich , i.e.the worse the health outcome of the poor is .Conclusion:Economic level is the primary factors affecting two weeks prevalence , age, culture level, the employment situation is the factors al-leviate health outcomes unfair .Increase people′s economic level and cultural level , improve the situation of em-ployment is important to the health equity .
ABSTRACT
Objective: To analyze the equity of benefit which residents with different income get from Urban Employee Medical Insurance ( UEMI) and New Rural Cooperative Medical System (NCMS). Methods: Data used in this study is based on the forth household health service survey in Shanxi province. The indirectly standardization method and concentration index were employed to analyze the horizontal inequity index of benefit rate and benefit degree. Results:The horizontal inequity index of benefit rate and benefit degree in UEMI are 0.0524 and 0.0025, and the horizontal inequity index of benefit rate and benefit degree in NCMS are 0.2312 and 0.3228. Conclusion: The urban residents get the equal benefit from UEM, and there were pro-rich horizontal inequities of benefit rate and benefit degree in NCMS.
ABSTRACT
Social governance is a novel form of public administration made based on the analysis and judgment for the power pattern in the course of social administration, a model advocated in the premise of a clearly positioned relationship among the government, marketplace, society and citizens.Social evaluation is an effective carrier and means leveraging the social governance theory, which has found extensive and outstanding use in such issues as expression of public interests and responsibilities,and in tackling sharp social problems. The authors called into play the scenario analysis based on public hospital management reforms with the social governance theory. In addition, they explored social governance at home and abroad as well as the theories, meaning and progress of social evaluation, and analyzed the pathways and probes in social evaluation and governance in the fields in question. On such basis, the paper proposed to explore and develop the social evaluation strategies and study framework for public hospitals in terms of healthcare management, aiming at building the social governance system and policies for public hospitals.
ABSTRACT
OBJECTIVE To investigate the properties of nosocomial infections among acute stroke victims,analyze the risk factors associated with these infections,and find out effective methods of care and management.METHODS Between Jan 2003 to Dec 2006,428 cases of stroke victims were studied to analyze the special properties and risk factors related to hospital infections among them.RESULTS Their nosocomial infection rate was 8.93%,repetitive infection rate was 9.41%,and the top five infected sites were the lower respiratory tract,digestive tract,urinary tract,upper respiratory tract and skin,with their respective rates as 47.66%,17.76%,15.19%,9.81%and 6.31%.The occurrence of hospital infections was associated with stroke as well as the quality of the nursing care process,invasive procedures,duration of stay in the hospital,dietary conditions,etc.CONCLUSIONS Nosocomial infection is still a high frequent complication in cerebral stroke and those related factors should be paid attention.To effectively decrease nosocomial infections related to stroke,it is necessary to improve nursing care and supervision as well as control over the quality of care.
