由于春运出湖北省高峰和全国各地管控开始之间的时间差,使得在这个时间段内,除湖北外的国内地区是个输入一代到感染二代之间独立自然连续传播体系。基于此,我们使用正态分布的线性叠加来拟合全国除湖北外每日新增的数据,简单模型预测和实际新增结果的高度吻合验证了除湖北外是个近似理想系统。拟合计算得到的新冠病毒可再生系数R0=2.2,一代到二代的峰值传播时间是7天。我们还讨论了偏离理想传播体系的原因并分析了一些省的特殊情况。

[Objective] Evaluate on the treatment efficacy and safety for transcranial magnetoelectric encephalopathy treatment instrument (brand name: AOBO Parkinson’s Treatment Instrument) treatmenting parkinson's disease. [Methods] Use methods of double center,randomized, double blind, self crossover, 22 Parkinson’s patients who met the inclusion criteria were randomly divided into A group and B group, then were carried on the curative effect analysis, and were observed therapeutic effect. [Results] The treatment group of 22 cases, basically cured in 0 cases, markedly effective in 9 cases, effective in 8 cases, ineffective in 5 cases. The total efficiency rate and total effective rate were 40.91% (9/22) or 77.27% (17/22) respectively. The control group of 22 cases, basically cured in 0 cases, markedly effective in 2 cases, effective in 3 cases, ineffective in 17 cases. The total efficiency rate and total effective rate were 9.09% (2/22) or 22.73% (5/22) respectively, the total effective rate and total effective rate in the treatment group were higher than those in the control group, the difference was statistically significant (P<0.05). Among them, the main symptoms of resting tremor, rigidity, bradykinesia, evaluation, the treatment group has significant difference (P<0.01); There was no significant difference in the control group (p>0.05); There was significant difference between the treatment group and the control group (p<0.05).

目的 探讨经颅磁电刺激(TMES)疗法对海仁酸(KA)致颞叶癫痫鼠的疗效。 方法 62只大鼠按照随机数字表法分为预处理组(共32只)和治疗组(共30只),预处理组再分为4个小组,分别给予治疗仪最大电流强度(MCI) 0%,25%,50%,75%的电流刺激,确定本实验条件下的最佳刺激参数。治疗组再分为3个小组,每组10只。2组(癫痫刺激组、癫痫非刺激组)为符合纳入标准的癫痫模型大鼠,刺激组刺激参数为预处理组确定出的最佳刺激参数;非刺激组大鼠刺激前后处理与刺激组相同,但治疗仪无有效的能量输出。第3组对照组为未造模对照大鼠。3组大鼠均给予每天1次,40 min/次,共14 d的刺激。记录并比较3组大鼠行为学、电生理学及组织学变化,以评估TMES疗法对癫痫大鼠的疗效。 结果 50%MCI为最佳刺激强度。癫痫刺激组大鼠癫痫波出现的频率明显低于癫痫非刺激组大鼠[(30.210 ±4.580)次/min vs. (31.380 ± 4.247)次/min],差异有统计学意义(t=3.235,P=0.001)。Timm染色结果提示3组大鼠染色评分差异有统计学意义(F=17.429, P=0.000),癫痫刺激组大鼠海马齿状回的内分子层Timm染色评分较癫痫非刺激组明显减轻,差异有统计学意义(P<0.05)。结论 TMES疗法可通过改善癫痫大鼠海马齿状回内分子层组织学变化程度来影响齿状回神经元环路的形成,进而降低癫痫脑电波的发作频率。

是一种基于经颅磁电刺激技术有效治疗帕金森病、阿尔茨海默病的新观点,可理解成电压门控钙离子通道物理激活最佳靶点假说,基本内容:帕金森病、阿尔茨海默病等神经元退行性变疾病,与物理门控离子通道密切相关,可用物理手段来解决,激活递质能神经元是治疗的关键,电压门控钙离子通道则是物理手段激活的最佳靶点,目的是诱导钙离子内流触发神经元轴突终末突触囊泡释放神经递质。脑细胞激活论,指出了阿尔茨海默病、帕金森病等神经元退行性变疾病的治疗原则、方法与目的,提示了试图通过药物化学手段来寻求神经元退行性变疾病的解决办法,可能会动摇我们应对疾病的信心,而物理手段的应用或物理化学手段的联合应用也许是我们今后应对一些重大脑病的主要科研方向。

This is a new idea that based on effective treatment of Parkinson's disease and Alzheimer's disease with transcranial magnetoelectric stimulation technology, it can understand a hypothesis about voltage-gated Ca2+ channels is the best target for activation by physical means, basic content:Parkinson's disease , Alzheimer's disease etc. neuronal degeneration diseases, that closely related to physical-gated ion channels, which can be treated with physical means, activating neurotransmitters-energic neurons plays key roles in the treatment, and voltage-gated Ca2+ channels is the best target for physical means, the purpose is to induce Ca2+ inflowing and triggers neuronal axon terminals synaptic vesicles releasing neurotransmitters. The theory of brain cell activation sets forth the principle, method and purpose of treatment of the physical gated ion channel diseases such as Alzheimer's disease, Parkinson's disease and other neural degeneration diseases, and indicates that the attempt to treat these diseases using pharmaceutical and chemical approaches could shake our confidence in conquering the diseases, and the application of physical approaches or combined application of physical and chemical approaches in the treatment of some major encephalopathy may be our main research direction in the future.
