本实验在64只氨基甲酸乙酯麻醉、断双侧迷走神经、自主呼吸的健康家兔上进行，观察电、化学刺激中缝背核、中缝大核对颏舌肌和膈肌肌电、以及窒息增幅反应的作用。

MSCs were cultured in a conditional medium in subculture including: dexamethasone, vitamin C, and β-glycerophosphate. At the same time, we constructed the eukaryotic expression vector containing VEGF165gene. VEGF165 gene was transfected into MSCs by means of LipofectAMINE?2000. The stably gene expressive cells were screened with G-418 for 14 days.

在脂质体介导下将构建成功的真核表达载体pcDNA3.1- VEGF165转染到诱导培养的MSCs，G-418筛选阳性细胞克隆，将阳性克隆细胞和未转染的MSCs共同接种于β-磷酸三钙上，体外培养7天后，植入原大鼠肌肉内。

This model considers more factors, especially great and complex effect of geological factors on grouting spread, Value of fissure aperture is cleared and defined, all kinds of parameters of geology and grouts property in connection with model can be tested accurately, therefore this approach practice more and have more practical value comparing with other grouting model to provide solid theoretical basis for grouting controlling method.

在频率水力隙宽和宾汉流体的渗流规律的研究成果基础上，考虑地下水影响半径、频率水力隙宽、粘度时变性、裂隙的倾角和方位角、流核等诸多影响因素，建立了牛顿流体和宾汉流体的注浆扩散模型，并对数学模型实现了计算机模拟，便于工程实际中的应用。

Morphology of sexual reproduction abortion in'High Noon', a distant hybridization cultivar of tree peonies(P.delavayi var. lutea×P. suffruticasa), was systematically investigated with light microscopy and cross. The results indicated that:(1)The stamens matured earlier than the gynoecia and pollens dispersed at the early stage of anthesis but the rate of normal 2-celled pollens were merely 2.41%.

采用光镜和杂交等方法对牡丹远缘杂交一代品种'正午'有性生殖败育进行系统形态学观察发现：(1)雄蕊较雌蕊先成熟，初花期即散粉，正常2-细胞花粉仅占2·41%，且花粉在多种培养液中、在自身和其它两种柱头上均不萌发；柱头在谢花期大量分泌粘液，进入最佳授粉状态；(2)同一胚珠中多个大孢子母细胞减数分裂高度不同步，胚囊发育与受精延迟，部分胚乳游离核在细胞化时期分裂异常；(3)自花及品种内异花授粉不结实，天然授粉结实率为0·053‰~0·130‰。

Based on the force analysis and strength check on the gyroscopic support, the original design has been improved, such as enlarging the diameter of steel material.

The embryological studies of strawberry showed that the ovule of strawberry were hemitropous, the ovule had the obvious hypostace structure, the type of its embryo sac was Polygonum, the embryo sac was long and narrow, the type of development of embryo was the Geum type of the Asterad type, the endosperm was Nuclear type and the somatic embryo sacs happened The integral transparency technique combined with the technique of microdissection was used in this experiment The combination was an innovation in the techniques of section.

对草莓胚胎学的研究结果表明：草莓胚珠横生、胚珠具明显的承珠盘结构、胚囊发育为蓼型、胚囊狭长、胚胎发育为紫菀型水杨梅类型、胚乳核型、并有体细胞胚囊的产生。试验中采用了多种制片方法，其中将整体透明技术和显微解剖技术相结合的方法是在制片技术上的一次创新。

The Taohezhenwu Decoction has good curative effect in treating and preventing CRF of rats induced with adenine by improving the renal function, electrolyte disturbances, acid-base equilibrium, hemophthisis and the function of SOD, reducing the harm of NO, TNF-α, and lessening or delaying the deterioration of nephron.

桃核真武汤能改善腺嘌呤大鼠慢性肾衰模型的肾功能、调节电解质酸碱平衡紊乱、纠正贫血、减少尿蛋白的丢失、减少NO与TNF-α损伤、提高SOD的保护作用、一定程度上防止肾单位的恶化，对SD大鼠腺膘呤所致之CRF的防治有肯定的疗效。

Results The average operation time was 23.5min. The average hospital stay was 3.5d. The correction of the prolapsed hemorrhoids was satisfied in 93.5% patients. Intraoperative hemorrhea occurred in two cases because the large range rectum mucosa was uncompletely stapled or cut. Urine retention occurred in 184 cases (31.9%), anal pain in 357 cases (62%) and a second operation were performed in 3 cases because of postoperative hemorrhea. A total of 484 cases were followedup for 14 years. The postoperative satisfaction rate of symptom improvement was 94 .3%. Four cases underwent thrombosed external hemorrhoid resection. Other patients had no recurrence, no anal stenosis and no fecal incontinence.

结果 手术时间平均23.5 min，平均住院时间3.5 d，切除痔上黏膜宽度平均约2.5 cm.93.5％术中痔核回缩满意，因大面积钉合不全及切割不全各1例发生术中大出血，尿潴留184例（31.9％），肛门疼痛357例（62％），3例术后大出血再次行手术止血。484例（84％）随诊1～4年，术后症状改善满意者94.3％，2例误诊，4例因血栓外痔行血栓外痔切除术，其余患者均无复发，无肛门狭窄、大便失禁。
