Path analysis showed internodal distance,first lateral branch number and whole-plant leaf weight with a significant positive effect on vindoline content (P.05), with path coefficients of 0.959, 0.716 and 0.431 respectively, which suggests that internodal distance, first lateral branch number and whole-plant leaf weight are the important factors in breeding C.

通径分析结果表明，长春花的主要农艺性状中，节间距、一级侧枝数和全株叶片重对文多灵含量的正影响达到了显著水平(P.05)，通径系数分别为0.959、0.716和。431，说明节间距、一级侧枝数和全株叶片重可以作为高含量文多灵长春花品种选育的重要参考指标。

Eighteen patients had multilevel anterior cervical discectomies with or without internal fixation, 22 patients had decompressive surgery (12 laminectomies and 10 intersegmental decompressions) for multiseg- ment spinal stenosis, 15 patients had laminectomy with posterior spinal fixation, and remaining 9 patients had laminectomy and excision of spinal tumor.

18例患者行多极前颈椎间盘切除术伴或不伴内固定， 22例患者因多节段椎管狭窄行减压手术（ 12例椎板切除术和10例节间减压）， 15例行椎板切除、后脊柱固定术，其余9例行椎板切除术和脊髓肿瘤切除术。

Although there is fair evidence that articial disc replacement is similarly effective compared to fusion for single level degenerative disc disease and that an interspinous spacer device is superior to nonsurgical therapy for 1- or 2-level spinal stenosis with symptoms relieved with forward exion, insufcient evidence exists to judge longterm benets or harms.

尽管已有相当的证据证明人工椎间盘置换治疗单节段脊柱退变疾病具有和融合手术类似的疗效，也有相当的证据证明棘突间支架治疗1～2个节段伴间歇性跛行的椎管狭窄的疗效优于非手术治疗，但以上都缺乏长期随访的证据。

Results: The thickness of intertransverse ligament was about 0.60~1.39mm.

结果：横突间韧带厚度0.60~1.39mm；L(下标 3-5)节段动脉前支及伴行静脉90%以上位于相邻横突间韧带腹侧上1/2处，横突间韧带背侧中1/3处有一恒定节段动脉分支；腰神经前支与矢状面夹角18.90°~39.20°，下位横突的副突处距前方走行腰神经前支距离为5.63~8.05mm，椎弓峡部侧缘至腰神经前支的距离为1.73~3.64mm。

Observing localization of the drug and morphologic change in DRG cells and motor neurons in spinal cord anterior hom after 1% adriamycin intraneural injection into the sciatic nerve of rabbits. Moreover, evaluating sensory and motor function 1-8 weeks following injection. Exploring whether the agent, injected into sciatic nerve, has the effect of chemo-ganglionectomy on the corresponding DRG.

研究家兔坐骨神经内注射1％阿霉素后，药物的聚集部位及相应脊髓前角运动神经元和背根节细胞的形态学变化，测定家兔1～8周下肢感觉及运动功能，探讨坐骨神经内注射阿霉素能否对相应背根神经节产生化学切除术作用。

We introduced improved primary mixed glial culture and different-attachment method to isolate and purify the OPCs, the cells were proliferated in serum-free medium, flow cytometry and immunohischemistry methods were employed to estimate the purity of cultured OPCs. Their abilities of differentiation and expression of trophic factors were identified by RT-PCR and immunostaining. Several methods including TUNEL and MTT were adopted to estimate the protective effects of conditioned culture medium from oligodendrocyte lineage cells on the primary cultured cerebellar granule neurons. Intravitreal transplant of OPCs, combined with retrograde fluorescent labeling the superior colliculus and intraorbital optic nerve transection, were used to investigate the protective effects of OPCs on the axotomized RGCs in vivo. Intravitreal transplantof OPCs or NSCs on the newborn rats, and retinal transplant of OPCs on the young rats were performed, to observe the myelin formation in the retina at different stages after cellular transplantation. Optic nerve transection was carried out on some rats with myelinated retinae, to study the influence of myelination on the injuried RGCs.

为此，本研究采用改良的胶质细胞混合培养与差速贴壁方法获得大鼠OPCs，使用无血清培养基进行扩增、培养，用免疫组织化学和流式细胞技术对培养细胞的纯度进行鉴定，对少突胶质系细胞表达部分营养因子的情况进行检测；采用TUNEL、MTT等方法对少突胶质系细胞条件培养基对原代培养小脑颗粒神经元的保护作用进行检测；将OPCs移植入成年SD大鼠玻璃体内，利用上丘逆行荧光标记技术，观察眼内移植的OPCs对眶内视神经切断时的视网膜神经节细胞的保护作用及其持续时间；将OPCs或NSCs移植入新生和幼年SD大鼠玻璃体或视网膜内，观察不同时期视网膜内髓鞘形成与分布特点，分析髓鞘的超微结构，并观察眼内髓鞘形成对损伤神经节细胞的保护作用。

The water content of external layer of root xylem of Kalidium foliatum is highest. In the range of root diameter from 0.3cm to 0.5cm,the most roots diameter are between 0.3cm and 0.5cm.

盐爪爪根的皮层含水量在径级为0.3－0.5cm范围内最高，大于0.5cm含水量反呈下降，而盐节木根径级在0.5－0.6cm范围内皮层和木质部含水量均最高，这可能是盐爪爪和盐节木根系径级分别多集中在0.3－0.5cm和0.5－0.6范围内的原因之一。
