社会力量参与公立互联网医院建设激励与约束机制研究

社会力量具备相应的经济基础和技术条件,对于公立互联网医院体系建设具有积极的促进作用。但是实践中仍然存在商业模式不完善、监管制度不健全等问题。基于经济学契约理论要义,提出在坚持激励与约束机制并举、平衡公私益关系的前提下,通过完善医保政策、构建互联网医疗服务价格分类管理机制来促进社会力量向医疗服务公益性目标回归,并通过构建完善的监督体制来约束部分社会力量的盲目逐利性行为。     

移动DR床旁胸部摄影应用价值的评估

<正>随着科技的进步,医疗技术的不断提高,使得诸多影像学检查在临床疾病诊断和治疗工作中发挥了重要作用。20世纪90年代末推出了数字X线成像(digital radiography,DR)成像系统,DR数字影像具有成像质量高,成像速度快,辐射剂量小等优点通过该系统,可以直接将X线信号转换为数字信号,既缩短了拍摄时间,同时由于自带显示系统,医生可以第一时间获得有关患者病情的清晰影像资料,这对于     

Evaluation of cisplatin-hydrogel for improving localized antitumor efficacy in gastric cancer

Gastric cancer, one of the most common disease, has become a major public health problem worldwide. Cisplatin (DDP) has been a widely used drug for the treatment of cancer, also usually applied in gastric cancer in clinic. However, the side effects including toxicity and drug-resistance restricted the usage of DDP in clinic, so we prepared a DDP-complexed hydrogel (DDP-Gel) and investigated its efficacy in gastric cancer. For in vivo studies, MKN45-Luc cells were injected into BLAB/C node mice subcutaneously to establish gastric cancer with orthotopically grown tumors. Mice bearing tumors were treated with normal saline, DDP and DDP-Gel. Body weight and survival condition were observed and recorded. The treatment efficacy in vivo was detected by luciferase imaging and histological evaluation was performed by H&E staining of different organs. Additionally, normal ICR mice were treated with different doses of DDP/DDP-Gel to calculate their LD₅₀ in vivo. The results showed that DDP-Gel prolonged survival time and ameliorated body weight changes of mice bearing tumors. DDP-Gel exhibited higher efficacy to inhibit tumor growth and metastasis, compared to DDP. Besides, LD₅₀ of DDP-Gel was 166.0?mg/kg, 13.2 folds higher than DDP. As a conclusion, DDP-Gel showed a more effective and safer function than DDP in gastric cancer, which indicating that DDP-Gel might be a novel strategy for gastric cancer therapy.     

2005 - 2014年中国老年人肺癌发病的时间趋势分析

目的 分析2005 - 2014年我国老年人肺癌发病的时间趋势，为我国肺癌的防控工作提供依据。方法 根据2008 - 2017年《中国肿瘤登记年报》中肺癌的相关数据，分析2005 - 2014年我国老年人肺癌的发病情况，并通过年度变化百分比（annual percentage change，APC）分析其时间变化趋势。结果 2005 - 2014年我国老年人肺癌的发病率呈上升趋势（APC = 0.71%，P＜0.05），其中农村老年人肺癌的发病率从198.9/105上升至250.7/105，上升趋势更明显（APC = 2.81%，P＜0.05），尤以农村老年女性肺癌发病率的上升趋势最为明显（APC = 5.26%，P＜0.05）。2005 - 2014年中国老年人肺癌的发病在60～64岁和65～69岁组呈上升趋势（APC分别为2.83%和2.04%，均P＜0.05），而在农村地区，老年人所有年龄组的肺癌发病率都呈明显上升趋势（APC分别为3.49%，3.86%，1.66%，2.31%，3.49%及6.37%，均P＜0.05）。结论 2005 - 2014年我国老年人肺癌发病上升趋势明显，以农村老年女性最为突出，国家应针对高危人群及早开展筛查等工作，降低我国老年人肺癌的流行水平。     

The Long-Term Effective Rate of Different Branches of Idiopathic Trigeminal Neuralgia After Single Radiofrequency Thermocoagulation: A Cohort Study

To evaluate the efficacy of computed tomography (CT) guided single radiofrequency thermocoagualtion (RFT) in 1137 patients with idiopathic trigeminal neuralgia after a follow-up period of 11 years, specially focused on duration of pain relief in different branches of trigeminal nerve, side effect, and complications.Retrospective study of patients with idiopathic trigeminal neuralgia treated with a single CT guided RFT procedure between January 2002 and December 2013.The mean follow-up time was 46.14 ± 30.91 months. Immediate postprocedure pain relief was 98.4%. V2 division obtained the best pain relief rate: 91%, 89%, 80%, 72%, 60%, and 54% at 1, 3, 5, 7, 9, and 11 years, respectively. No statistical difference pairwise comparison was in other groups. The complications included masseter muscle weakness, corneitis, diplopia, ptosis, hearing loss, limited mouth opening, and low pressure headache. Masticatory weakness mostly occurred in patients with V3 branch involvement, while Corneitis and Diplopia all in patients with V1 branch involvement. No mortalities observed during or after RFT.All different branches division of trigeminal neuralgia achieved comparable satisfactory curative effect; V2 obtained the best excellent pain relief, after RFT procedure. Facial numbness is inevitable after RFT, which patients who have pain in all 3 trigeminal divisions and patients who desire no facial numbness should be cautious. Masticatory weakness is mainly related with V3 injured, while Corneitis and Diplopia in patients with V1 injured by RFT.     

肝移植术后认知与脑改变的多模态神经成像

肝性脑病是终末期肝硬化的重要并发症,导致病人出现一系列神经及认知功能改变。肝移植术后病人在肝功能恢复的同时其认知功能也可明显改善。MRI可以从脑代谢、结构及功能方面更进一步揭示肝硬化病人移植术后认知及脑改变情况。综述肝移植术后认知改变的研究现状以及最新的多模态MRI技术在术后脑改变中的应用,及其在揭示术后认知恢复及残存损害的神经机制中的价值。     

The quality of spontaneous adverse drug reaction reports from the pharmacovigilance centre in western China

Background: High-quality adverse drug reaction (ADR) reports are essential for conducting drug safety monitoring in pharmacovigilance. The study aim was to assess the current quality of ADR reports in western China, and to identify problems with ADR report quality.

Research design and methods: A sample of 1139 reports received by the Shaanxi ADR Monitoring Center from January 2015 to December 2017 was selected. ADR report quality was evaluated using an ADR report quality evaluation system.

Results: None of the reports were rated as excellent and 1.40% (n = 16) as good. Report quality was better for new and serious reports than for general reports. Medical institutions generated higher quality reports than pharmaceutical manufacturers. Nurses generated higher quality reports than doctors, pharmacists, and other professionals. Reporters of different occupations showed significant differences in the quality of the indicators Reporting time limit, Intervention ADR time, ADR termination time, ADR intervention measures, Original disease, and Cause of medication (P = 0.000).

Conclusions: The ADR data quality was poor in western China, and of lower quality than reported data from previous research in other regions. Improvements in the quality and availability of ADR reports are urgently needed.
