Lacunar infarction in patients with hypertension is also common cerebrovascular disease, clinical manifestations of light, many people without clinical symptoms, and in nuclear magnetic resonance, CT examination or autopsy, was found when more specific clinical symptoms are: a simple movement obstacles, mild hemiplegia, aphasia or without sensory disturbance; pure sensory disturbance, migraine paresthesia or loss of body; dysphonia - clumsy hand syndrome, manifested as paresis and paralysis of tongue, speaking clearly, swallowing difficulties, fine motor hand and foot less flexible; ataxia and hemiparesis, inability to break limbs and lower limbs than upper limbs, uncoordinated movements, these symptoms often disappear in two weeks.

腔隙性脑梗塞也是高血压患者中常见的脑血管病，临床表现较轻，很多人无临床症状，而在核磁共振，CT检查或尸体解剖时才被发现，较为特殊的临床症状有：单纯运动障碍、轻度偏瘫，不伴失语或感觉障碍；单纯感觉障碍、偏身感觉异常或丧失；发音障碍-手笨拙综合征，表现为轻瘫和舌瘫、说话不清、吞咽困难、手脚精细运动欠灵活；共济失调性轻偏瘫，肢休无力、下肢重于上肢，运动不协调，这些症状常可在2周内消失。

Some scholars have suggested in recent esophageal cancer in vitro three-field irradiation method, subparagraph hyperfractionated radiotherapy, and the introduction of 60 Co, 137Cs, 192Yb esophageal cavity Brachytherapy to reduce lung tissue and spinal cord suffered while reducing the radiation dose radiation injury, increased radiation therapy.

在这个补偿系统中，可能会产生激光棒和透镜横向或纵向未校准以及激光棒倾斜而导致的未校准等情况，我们对于激光腔内每一种未校准而产生的退偏损耗进行了理论分析。

The mice in experimental group and control group were exposed to 350 cGy radiation produced by 60Co. After 3 h, karyocytes at different concentrations in the fresh human umbilical cord blood were injected into the mice in experimental group A, B, C via their tail veins, and the equal volume of normal sodium was also injected into control group via tail veins. After one month, carbon tetrachloride (CCl4) was injected into experimental group A, B and control group via abdominal cavity, and the equal volume of normal sodium was injected into experimental group C. After two months, immunohistochemistry and reverse transcriptase polymerase chain reaction were used to detect the expressions of human cytokeratin-18 (CK18), cytokeratin-19 (CK19) and albumin in liver tissues of all mice.

采用60Co治疗仪γ射线对实验组和对照组行350cGy的亚致死剂量照射，实验组A、B、C3组照射后3h内经尾静脉分别输入1.0×10^7个/只、2.0×10^7个/只和3.0×l0^7个/只人新鲜脐血有核细胞，对照组经尾静脉注入等体积无菌生理盐水。1个月后对实验A、B组和对照组裸鼠经腹膜腔注射四氯化碳(CCl4)，实验C组注射等体积生理盐水。2个月后采用免疫组化和RT-PCR方法检测裸鼠肝组织人源性CK18、CK19和人源性白蛋白的表达。
