有脐的

Results There was no obvious discrimination of the seed morphology between AMM and AM.

结果通过肉眼和光学显微镜观察，两种黄芪种子的形态差异不明显，在电子显微镜下观察，两种黄芪种子的萌发孔形状、种脐和种皮的微观结构有明显差异；蒙古黄芪较膜荚黄芪种子硬实率高，萌发不整齐，萌发高峰滞后。

Species of Rytidosperma lack cleistogenes, and also differ from the above description in having lemma hairs in tufts, ciliate lodicules, and a punctiform hilum.

Rytidosperma的种缺乏闭花受精植物，以及在有外稃毛成丛，具缘毛的鳞被和一点状的种脐方面不同于上述描述。

Wing articulated to seed; needles 2-5 per bundle; apophyses and umbo of different types.

Bladder artery comes from umbilical artery and along the bladder border to the bladder top and branchestoward bladder ventrally or dosally wall.

膀胱动脉主要起自脐动脉，沿膀胱侧缘行向膀胱顶，沿途发出1～4支基本对称的分支分布于膀胱前面，两侧膀胱动脉的分支在其表面有吻合现象。

ConclusionHCMV infection significantly down-regulated the expression of HOXB6 gene.The result suggests that the abnormal expression of HOXB6 gene induced by HCMV may play an important role in HCMV-induced abnormal hematogenic damage.

结论HCMV感染能诱导脐血红系祖细胞HOXB6的表达下调，HCMV有可能通过调控HOXB6基因表达异常而引起红系祖细胞的增殖障碍。

In recent years,human umbilical vein endothelial cells have highly application value in gestational hypertension and phlebothrombosis research.

近年来，人脐静脉内皮细胞在妊娠高血压综合征、静脉血栓等方面的研究中有很高的应用价值。

Vein transplantation of human UCB-MSCs has protective effects on splenocyte damages induced by irradiation, can promote proliferation and accelerate repair of splenocytes. The action mechanism is associated with elevating natural killer cell activity, and number of CD4+ and CD8+.

脐血间质干细胞静脉输注对辐射造成的脾细胞损伤有一定保护作用，可促进脾脏细胞的分裂增殖，加速脾脏细胞的修复，其作用机制可能与提高NK细胞活性和CD4+、CD8+数量有关。

Surface urothelial involvement by carcinoma and presence of cystitis cystica/glandularis do not necessarily exclude the diagnosis of urachal carcinoma.

癌组织中混有膀胱表面的尿路上皮和囊性/腺性膀胱炎成分，都不能排除脐尿管癌的诊断。

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。

Objective: To investigate the relationship of the systolic/diastolic ratio in the umbilical artery and gestation ages of normal fetus and to study the difference of the S/D ratio between the northeast region and the southwest region of China.

目的：探讨胎儿脐动脉的S/D值与孕龄的关系，把东北与西南地区的S/D值对照，探讨两地的S/D值是否有差异。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.
