Onehealth, an evidence-based decision-making software, is based on the United Nations' epidemiological reference modules to predict the effect of health services. Onehealth is a large database. The software is using activitybased costing, simulating investment costs of health system and changes of mortality in different coverage levels. By the cost of inputs/avoid deaths, it could quantify the cost of health services effectiveness and provide an intuitive basis for the rational allocation of health resources. This study introduces the relevant concepts, model structures and applications of Onehealth. We took the study of child nutrition interventions in Sudan for example and to present Onehealth tool's operating. As a new auxiliary and evidence-based decision-making software with scientific and rigorous theoretical approach, Onehealth has practical significance on the national or regional macro decision-making.
ObjectiveTo study the long-term prevention effect of self-developed chitosan electrospun membrane on cerebrospinal fluid leakage. MethodsTwenty-five healthy adult New Zealand rabbits were selected to prepare the bilateral dural defect (0.8 cm×0.8 cm in size) via midline incision of head.Defect of the right was repaired with chitosan electrospun membrane as the experimental group; defect of the left was not repaired as the control group.At 2-16 weeks after operation,one rabbit was sacrificed for the general observation of inflammatory response surrounding bone window and absorption of chitosan electrospun membrane; at 3 and 6 weeks after operation,5 rabbits were sacrificed for sampling to observe histological change and collagen expression by HE and Masson staining,and to measure the expressions of epidermal growth factor receptor (EGFR) and basic fibroblast growth factor (bFGF) by immunohistochemical staining. ResultsNo inflammatory reaction of swelling,exudation,and sppuration appeared in the skin and subcutaneous tissue after operation in 2 groups.There was no adhesion around the chitosan electrospun membrane,and new fiber membrane formed under the chitosan electrospun membrane in the experimental group; no cerebrospinal fluid leakage happened; the chitosan electrospun membrane was gradually degraded with time,and was completely absorbed at 16 weeks.There was uneven scar around the dural detect in control group.Histological observation showed less inflammatory cell infiltration in the experimental group,showing significant difference in the number of inflammatory cells compared with control group at 3,6 weeks (P<0.05); capillary,granulation tissue and collagen fiber massively proliferated; collagen fiber arranged in line,and there was a clear borderline between chitosan electrospun membrane and adjacent collagen fiber.The immunohistochemical staining showed that there were high expressions of bFGF and EGFR in the experimental group,and low expressions of bFGF and EGFR in the control group. ConclusionChitosan electrospun membrane for dural defect of rabbit can effectively reconstruct the dura,and it has exact long-term prevention effect on cerebrospinal fluid leakage.
目的 探討經陰道B型超聲（B超）在診斷早期宮外孕中的臨床應用價值。 方法 回顧分析2011年5月－2012年3月應用陰道B超與腹部B超對78例宮外孕患者進行對比檢查的臨床資料并回顧性分析，評價兩種檢查方法的臨床效果。 結果 78例宮外孕患者，應用經陰道B超檢查診斷準確率為97.44%，應用腹部B超準確率為61.54%，差異具有統計學意義（χ2=6.472，P＜0.05）；經陰道B超檢查診斷附件包塊、宮內假孕囊、心血管搏動、胚芽、盆腔積液的檢出率明顯高于經腹部B 超檢查的檢出率（P＜0.05）。 結論 陰道B超具有操作簡單、快速、無副作用、無需充盈膀胱等優點，在宮外孕的早期診斷中具有絕對的優越性，為臨床提供了更方便、更快捷的診斷手段，減輕了患者痛苦，提高了診斷的準確率，值得臨床廣泛推廣和應用。
ObjectivesThis study aimed to study the economic effect of five kinds of detection systems for nucleic acid, which were based on five kinds of working electrodes: gold electrode, glassy carbon electrode, carbon paste electrode, screen printing electrode, and indium-tin-oxide (ITO) glass electrode.MethodsThe cost of completing a single test was taken as the cost of economic analysis. The Youden index was used to represent the effect of cost-effectiveness analysis (CEA). Meanwhile, the cost-utility analysis (CUA) and incremental cost-effectiveness ratio (ICER) were used for the economic analysis of the corresponding system.ResultsThe cost of five detection systems based on gold electrode, glass carbon electrode, carbon paste electrode, screen printing electrode, and ITO glass electrode was 3.70 yuan/unit, 4.20 yuan/unit, 5.25 yuan/unit, 33.98 yuan/unit and 5.01 yuan/unit, respectively. The Youden indexes of all five systems were 1. The cost effectiveness (C/E) were 3.70, 4.20, 5.25, 33.98, and 5.01, respectively. The cost utility (C/U) were 6.61, 6.89, 9.91, 62.93, and 9.45, respectively. The C'/E and C'/U of the gold electrode detection system were the minimum (2.96 and 5.29). Compared with the system applying the gold electrode, the system using the glassy carbon electrode had ΔC >0 and ?E0 >0; When carbon paste electrode, screen printing electrode, and ITO glass electrode system were used, ?C was >0 and ?E0 was <0.ConclusionsFrom the perspective of CEA and CUA, the system using the gold electrode has the best economic effect. The sensitivity analysis proved the reliability of CEA and CUA results. According to the ICER, gold electrode or glassy carbon electrode can be used in clinical practice with the choice depending on the user.
Objectives To describe background, measures and impacts of building essential healthcare system in the developed and developing countries aboard. Methods Search words were chosen by both health policy experts and search coordinators after discussion and pilot. The resources we searched included electronic databases, websites of health institutions and governments and search engine Google. Any reports of implemented strategy to develop an essential healthcare package were included. Pre-designed data extraction form was used for collecting strategies and study method of included studies. Then the extracted information was analyzed and described. Result 166 studies covering 72 countries were included, most of which were studies in the middle and low Countries. In terms of study objectives, many studies (160 articles) aimed to describe strategies, while few studies(6 articles) were to evaluate effectiveness of strategies. Most of studies evaluating effectiveness were cross-sectionnary data, Except one time cohort study with intervention. Conclusions Strategies to implement essential healthcare system varies in the different country because of diversity of political, culture and economic background and different goals. The experience in transition countries gives us more high lights.
Objective To compare the economic effectiveness of universal screening, high-risk population screening, and no screening strategies for thyroid disease prevention and control among pregnant women in China through cost-effectiveness analysis, providing evidence-based support for optimizing health policy decisions on prenatal thyroid disease screening. Methods Based on the characteristics of thyroid disorders during pregnancy, a combined decision tree and Markov model was developed to conduct a lifetime cost-effectiveness analysis across three strategies: no screening, high-risk population screening, and universal screening. Sensitivity analyses were performed on key parameters. Results Base-case analysis demonstrated that universal screening was the most cost-effective strategy when the World Health Organization (WHO)-recommended payment threshold of 1×gross domestic product (GDP) per capita was used, with an incremental cost-effectiveness ratio (ICER) of 20636.18 yuan per quality-adjusted life year (QALY) compared to no screening, followed by high-risk population screening (ICER=21071.71 yuan/QALY). The results of the sensitivity analysis showed a strong stability of the model. Conclusions Of the 3 screening programs for thyroid disease in pregnancy, universal screening is the most cost-effective when the WHO-recommended payment threshold of 1×GDP per capita is used.
