Indicators like means,increase（decrease） percentages were used to descriptively analyze the average hospitalization expense of each time（AHEET） and its trends of breast cancer patients with different medical insurance coverages treated in medical institutions of different types and grades.Results：In 2011–2015,the AHEET borne by breast cancer patients in China had been constantly increasing.Specifically,the self-pay inpatients had the largest increase,inpatients covered by Urban Employee Basic Medical Insurance（UEBMI）and Urban Resident Basic Medical Insurance（URBMI）were the next,and those covered by New Rural Cooperative Medical System（NRCMS）had the least increase.Breast cancer inpatient treated in public hospitals had quite greater increase and higher expenditure level than those in private hospitals.The AHEET borne by the inpatients in Grade 3 hospitals had greater increase and higher cost than those in Grade 2 hospitals.Conclusions：The inpatient payments of breast cancer patients will be wisely controlled by reducing the number of self-pay inpatients,taking advantage of restriction mechanism of the medical insurances,and promoting healthy competition between private hospitals and public hospitals.The economic burden imposed on the society by breast cancer can be relieved through further control of inpatient payments of UEBMI-and URBMI-covered breast cancer patients and of Grade 3 hospitals.展开更多

文摘目的观察间歇有氧训练对低氧肺动脉高压(hypoxic pulmonary arterial hypertension,HPAH)大鼠的肺动脉压及肺小动脉结构的影响,探讨间歇有氧训练改善HPAH的机制。方法30只雄性SD大鼠随机分为对照组、HPAH组、康复组,每组各10只。HPAH组及康复组给予低氧环境(氧浓度9%~11%,8 h/d,持续4周)建立大鼠HPAH模型。康复组在造模后给予间歇有氧训练4周。干预完成后测定各组大鼠的平均肺动脉压(MPAP)与右心室肥厚指数(RVHI);观察肺动脉病理学改变并测定肺小动脉管壁厚度/血管外径(MT%);检测自噬相关指标Beclin-1、LC3的蛋白表达。结果HPAH大鼠MPAP、RVHI指标与对照组(12.52±2.60)mmHg(1 mm Hg=0.133 k Pa)、(21.37±3.75)%相比,HPAH组和康复组的MPAP、RVHI均升高,但康复组(26.14±4.21)mmHg、(28.09±4.43)%低于HPAH组(40.41±3.97)mmHg、(47.92±5.57)%,差异具有统计学意义(P<0.05)。HPAH组MT%(51.77±4.44)%明显高于对照组(29.38±3.07)%,肺血管重构明显;康复组MT%(40.07±2.95)%较HPAH组明显下降,肺血管重构程度减轻。HPAH组和康复组大鼠肺组织自噬标志性蛋白Beclin-1、LC3蛋白表达较对照组均增加;但康复组Beclin-1、LC3蛋白表达明显高于HPAH组(P<0.05)。结论间歇有氧康复训练可降低肺动脉压,改善HPAH大鼠肺动脉重构,其机制可能与间歇有氧康复训练激活自噬相关。
