超低频脉冲磁场抑制癌瘤和提高细胞免疫功能的实验研究

在报道用电子显微镜观测超低频脉冲磁场(峰值磁场0.6～2.0T,磁场梯度10～100T·m^-1,脉冲宽度20～200ms,重复频率0.16～1.34Hz)抑制鼠S-180肉瘤和加强免疫细胞溶癌作用以后,报道了用Faulgen染色法测定肉瘤细胞核的DNA倍性,和用电镜技术和细胞结构的体视学分析磁场对癌细胞形态的影响,观测到磁场影响癌细胞的代谢:磁场使癌细胞的恶性程度降低,抑制其高速和异形生长;磁场抑制癌细胞的分裂和DNA的复制;磁场提高细胞免疫功能,加强淋巴细胞、浆细胞反应.     

Experimental studies on extremely low frequency pulsed magnetic field inhibiting sarcoma and enhancing cellular immune functions

The previous observation with an electron microscope showed that extremely low frequency (ELF) pulsed magnetic field (PMF) (with the maximum intensity of 0. 6-2. 0 T, gradient of 10-100 T. M-1, pulse width of 20-200 ms and frequency of 0. 16-1. 34 Hz) inhibited the growth of S-180 sarcoma in mice and enhanced the ability of immune cell's dissolving sarcoma cells. In this study, the DNA contents of nuclei were assayed by using Faulgen Staining method. With an electron microscope and cell stereoscopy technology it was observed that magnetic field affected the sarcoma cell's metabolism, lowered its malignancy, and restrained its rapid and heteromorphic growth. The magnetic field enhanced the cellular immune ability and the reaction of lymphocytes and plasma. Since ELF pulsed magnetic fields can inhibit the growth of sarcomas and enhance the cellular immune ability, it is possible to use it as a new method to treat cancer.     

公立医疗机构产权制度民营化改革的经济规范分析

????? 公立医疗机构民营化改制是我国医疗体制改革中颇受争议的热点。从经济学角度规范分析,医疗服务的私人物品特点是民营化的基本前提,收紧预算约束、提高效率是民营化的主要依据。在民营化过程中,地方政府充当了民营化改制的推力,条块冲突主要影响了民营化的整个进程。在目前回归公益为主的政策引导下,民营化将不会作为未来医疗体制改革的重点,但局部民营化仍应得到积极实施,兼顾机构职工与患者利益条件下未来民营化进程将呈现复杂形态,而分部门、分机构、分地区的改制试点将是下一阶段民营化发展的主要方向。
