METHOD: I review the literature on the efficacy and complications of four frequently used neurosurgical procedures (cingulotomy, capsulotomy, limbic leucotomy and subcaudate tractotomy) that are used to treat refractory OCD.

我回顾了文献中关于四种手术方式的有效=性和并发症（扣带回切开术、内囊切开术、边缘系统白质切开术、尾状核下神经束切开术）。

The results are summarized as follows: tin the polygonum embryo sac of tetraploid grape , megaspore telrad arranged in straight line.

结果如下：在四倍体葡萄的蓼型胚囊中，四分体孢子呈直线排列，合点端的大孢子发育胚囊。

The megaspore mother cell is located at the 3rd or 4th layer of cells in the nucellus top end. It divides transversally to form a linear megaspore tetrad, and the megaspore at the chalazal end develops into the embryo sac mother cell.

大孢子母细胞位在珠心顶表皮下第三或四层细胞处，经横分裂后产生一直线形的大孢子四分体，其中位居合点端的大孢子发育成胚囊母细胞。

Afterwards, releases were carried on by the sequences: suprapatellar bursa; medial and lateral channel; medial and lateral patellar retinaculum; patella/femoral joint; condyloid socket; medial and lateral chamber; adhesion between femoral and quadriceps.

方法］釆用膝前内、前外及骸骨内上、外上4个5~10mm切口，先松解、扩张髌上囊创造出进入关节镜的空间，依照髌上囊→内、外侧沟→髌骨内、外侧支持带→髌股关节→髁间窝→膝关节内侧室→外侧室→股骨与股四头肌之间的粘连顺序进行松解。

Objective: To investigate the effect of diclofenac sodium to the changes of MMS,PGs in aqueous humor in rabbit after Nd:YAG laser posterior capsulotomy.

目的 ：探讨双氯酚酸钠对兔眼Nd ：YAG激光晶体后囊膜切开术后房水内中等分子物质及花生四烯酸代谢产物变化的影响。

The result showed that:CSCCa in 18 cases were classfied into four types: Infit rative type; Cystis type ; Aarefying type ; Spread hollow .The study proposed the differential diagnosis in CSCCa with metastic tumor,intrabong cyst and rarefying osteomyelitis.

结果显示 18例CSCCaX线分四型：即①浸润型；②囊腔型；③疏松型；④凿孔型，并提出了CSCCa与颌骨囊肿、癌瘤、疏松型骨髓炎的鉴别诊断。

Our study includes four aspects. In the first aspect we study several important conditions of porcine oocytes maturation in vitro and oocytes cleavage after parthenogenetic activation and found mNCSU-23+15IU/mlPMSG+20IU/mlHCG+15% PFF+0.57mMcysteine is a good culture condition .When the Cocs are cultured in it ,the maturation rate and oocytes cleavage rate are higher than those of foreign covered. Our result are (86.7±3.35)% and (86.3±4.16)% and the highest report of foreign is(85.7±4.1)%.In the second aspect we study the effect of different chemical activations on development of porcine parthennogenetic embryo and found two best activation method. The first one is that putting the maturation MII oocytes in the 20μmol/L ionomycin for 30 minutes and then putting them in the NCSU-23 condition containing 5μg/mICB and 5mM/L6-DMAP for 3.5 hours, the oocytes cleavage rate and morulae/blastocysts development rate are (76.7±7.6)% and (37.1±6.4)%.The second one is that putting the maturation MII oocytes in the 200μM/L Thimerosal for 20 minutes and then putting them in the NCSU-23 condition containing 8mM DTT for 30 minutes

本研究分为4个部分，第一部分对影响猪卵母细胞体外成熟和孤雌激活后胚胎分裂的几个重要条件进行了比较研究，确立了一种较好的培养方法：与颗粒细胞共培养，找到了一种适合猪卵母细胞体外成熟的培养基：mNCSU-23+15IU/mlPMSG+20IU/mlHCG+15%PFF+0.57mM半胱氨酸，成熟率和分裂率分别为(86.7±3.35)%和(86.3±4.16)%，国外报道的最高成熟率为(85.7±4.1)%；第二部分对猪卵母细胞孤雌激活的化学方法进行了研究，确立了化学激活猪卵母细胞的两种最佳方法：1将成熟的去卵丘颗粒细胞的MII期卵母细胞用20μmol/Lionomycin作用30min，再将卵母细胞培养于含5μg/mlCB和5mM/L 6-DMAP(6-二甲基氨基嘌呤)的NCSU-23培养液中，卵裂率和桑囊胚发育率达到(76.7±7.6)%和(37.1±6.4)%2将成熟的去卵丘颗粒细胞的MII期卵母细胞在200μM/L的Thimerosal中处理20min，再与8mM的DTT共孵育30min，卵裂率和桑/囊胚形成率为(81.0±2.8)%和(39.6±2.7)%；第三部分对孤雌激活胚胎的培养条件进行了研究，确立了一种最佳的胚胎培养条件：在SOF简单培养基中添加颗粒细胞进行前3天的培养，然后转入添加胎牛血清的NCSU—23培养基并和输卵管上皮细胞进行后期的培养，其桑椹胚和囊胚的发育率为(59.5±3.2)%；第四部分研究了IGF-I

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
