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.

The most serious desertification occurred in southeast of MuSu Desert,then appeared inferior degree in midst,north,south and east,anddegression degree in other directions.6.The changes of environment in Mu Su Desert in historical times havebeen controlled by climatic changes in temperature and drought-wetwithin hundreds or thousands years.At present,it came into being suchspatial structure and environmental characteristics fordesertification land because of being relative to other naturalgeographic characters and human activities.In all that,physiognomyand hiemal wind are the driving factors.The sandy matter in stratumis the physical fountain factor.The depravation of surface water inthis region is one of representations of environmental changes, meanwhile,it is also the factor which leads to the degradation ofvegetation and desertification.On the whole,human activity has actedupon these natural elements,becoming a dominant factor in the regionalenvironment changes since Ming and Qing dynasty.7.Influencing of human activities on the environment of Mu Su Deserthad occurred before Qin dynasty,and its intensity of earlier influencewas so slight that it could not cause a large scope and long timeenvironmental changes.

沙漠化的程度是东南部最强，中北部、南部和东部次之，而后向其他方向递减。6、毛乌素沙地历史时期的环境变化是受百年乃至千年尺度的气候冷暖、干湿变化控制的，之所以形成目前这样的沙漠化土地空间分布格局和环境特征，则与其地的自然地理特征和人类活动有密切关系，其中地貌及冬季风是动力因素；地层中的沙物质是物源因素；地表水环境恶化是区域环境变化的表现之一，同时又是植被退化和沙漠化的引致因素；人类活动总体上是叠加在自然因素之上的，只是明清以来在局地环境变化中成为主导因素。7、毛乌素沙地人类活动的环境影响在先秦时期就已出现，早期的影响程度是轻微的，不足以造成大范围、长时段的环境变化。

RESULTS Pe-ripheral whole blood cells of this experimental rabbit re-duced,and by PCR,no donor's cell was found,and slight defective profileration of marrow occurred;the pathologic re-sults showed that its pathological processes mainly occurred in its skin and were all slighter than homogenic GVHD,and there was no obvious difference in the invaded regions be-tween heterogenic and homogenic GVHD.

The pattern of lunar cycle can be classified into three strategies:(1) Planulation of S. hystrix and P. damicornis showed clear lunar periodicity and the peak of larval release shifted with different months. The peak of planulation occurred around the full moon in winter then shifted gradually to the first quarter moon phase in summer. The phase shift of larval release may be related to the seasonal variation of seawater temperature and the sudden temperature drops caused by upwelling.(2) Planulation of S. pistillata showed clear lunar periodicity and the peak of larval release occurred around the full moon.

在月周期方面可分成三种生殖策略：(1)尖枝列孔珊瑚与细枝鹿角珊瑚释放幼生不但有明显的月周期，而且释放幼生的高峰会随著月份而移动，由冬季至夏季期间，高峰从满月前后转变至上弦月前后；再由夏季至冬季期间，高峰从上弦月前后转变至满月前后，而此变动形成一个完整的年周期，原因可能与海水温度影响配子发育和胚胎速度与夏季期间涌升流所造成的降温有关。

With regard to the control issue from the aspect of the political science, Chapter Seven takes the relationship between farmers of China's southwest region and the local government as the subject investigated, discussed the contradictions, conflicts and even intensification of interests occurred during the time of the tobacco monopoly control, and touches many incredible inharmonic phenomena occurred under the background of the monopoly control by the central government even in the undeveloped countryside. Such inharmonic phenomena made, of course, farmers who planted and/or sold tobacco be in hot water, which led to the economic rational resistance against the behaviours of the local government that made people work hard and wasted money for nothing.
