In the process of laboratory study, oxycodone was prepared by oxidating thebaine at 6,14-position under oxydol, hydrodeoxidizing 7,8-position double bond and 14-position ether under palladium catalyst. Furthermore, N-methyl of oxycodone was isolated byα-chloro-ethyl chloroformate under anhydrous condition and protection of 14-position hydroxyl to obtain noroxycodone, which was further converted into methylnaltrexone by N-alkylation in presence of cyclopropyl bromomethane, then by isolating 3-position methyl of methylnaltrexone under boron tribromide, becoming hydrochloride to prepare target compound, natrexone hydrochloride.

实验室工艺方面，本文首先用双氧水氧化蒂巴因的6-位和14-位、在钯炭催化下加氢还原7-8位双键和14-位醚合成羟考酮，然后提出并优化了在无水和14-位保护的情况下，用氯甲酸-α-氯乙酯脱去羟考酮的N-位甲基合成去甲羟考酮，再用环丙甲基溴将去甲羟考酮的N-位烷基化合成甲基纳曲酮，最后采用三溴化硼脱去甲基纳曲酮的3-位甲基和成盐酸盐合成盐酸纳曲酮。

Their 95% effective concentration (EC95) value was 0.4735 μg/mL. Flumorph at the concentration of 0.5 μg/mL, can lead the inhibit rate of growth of mycelium, formulation of sporangium and germination of zoospore of Phytophthora sojae to 100%, the concentration was lower than Apron XL, Metalaxy which lead to the same inhibition rate. It indicated that Flumorph can obviously inhibit the growth of P.sojae in vitro, and effect is better than that of Apron XL and Metalaxy.

结果表明：氟吗啉对所测定的菌株4个发育阶段均有显著的抑制作用，氟吗啉对大豆疫霉菌菌丝生长EC50 值为0.1906μg/mL，EC95 值为0.4735 μg/mL；在0.5 μg/mL 浓度下对大豆疫霉菌孢子囊形成和孢子萌发抑制率达100%，低于达到相同抑制效果的金阿普隆和甲霜灵；说明该药剂在离体条件下能够有效抑制大豆疫霉菌的生长，效果好于金阿普隆和甲霜灵。

The available operation range in clivus and anterior cranial base by transsphenoidal opproach was also observed during the operation under the help of neuronavigational pointer. Forty-one patients underwent sublabial, transseptal, transsphenoidal approach to the pituitary region guided by Surgical Microscope Navigation was studied. The piriform aperture was 27. 2mm±3. 1 , the origin of inferior nasal concha 30mm±4. 1, the origin of middle nasal concha 27. 9mm±4. 3. These data are important for transsphenoidal approach, because the piriform aperture and the origin of both inferior and middle nasal conchas restricted the opening width of the Hardy specula. If any distance of these bony structures was much less than the mean one, may cause inadequate opening of the specula blade and resulting dissatisfied operative field. Microadenomas or cystic tumors perhaps can be operated even in a narrow exposure, but large or giant solid adenomas may need a proper evaluation including changing the operative approach or performing a bilateral submucous inferior conchotomy or posterior ethmoidectomy firstly.

手术中还利用CT导航系统观察棒研究了经口—鼻蝶窦入路在斜坡区和前颅底能够达到的实际有效操作范围，为扩大经蝶窦入路手术在斜坡区和前颅底的应用奠定基础，在国内外尚未见同类报道。41例垂体瘤患者梨状孔平均宽度27.2mm±3.1，下鼻甲根部附着处间距30mm±4.1，中鼻甲根部附着处间距27.9mm±4.3，这是经口—鼻蝶窦入路手术中，对Hardy双瓣鼻窥器张开限制的主要骨性结构，若患者这些径线值明显小于平均值，则可能因为鼻窥器打开不充分而影响手术暴露，当然对于垂体微腺瘤和以囊变为主的垂体瘤可能影响不大，但对于大和巨大垂体瘤必须要有充分的准备，包括评估是否改用其他入路，或先行鼻甲切除再行经蝶手术。

The results show that the foamable MAA/MAN copolymers were prepared at 40-60℃ by polymerizing the mixture of 50phr MAA, 50phr MAN, 1-5phr magnesium oxide, 2-8phr butanol and tert-butanol, 0.2-0.3 phr dibenzoyl peroxide and tert-butyl perbenzoate and 0.1-0.2phr DMF. Then the resulting copolymers were expanded at 200-220℃ for 2-3h, subsequently treated at 160℃ for 5-6h, generating PMI foams with excellent mechanical properties and heat-resistance.

Since the lesion presented above is localized both intra- and extralaryngeal, herniates through the thyrohyoid membrane into the submandibular space, is fluid-filled and communicates with the laryngeal ventricle, the cyst is most likely a mixed laryngocele. Differential diagnosis consists of ventricular appendix, thyroglossal duct cyst, submucosal cyst, abscess or pyolaryngocele.

如果一个病变表现为局限性的喉内或喉外病变，通过甲状舌骨膜疝入到下颌下间隙，其内充满了液体，通过喉室相交通，最有可能的就是混合性喉气囊肿，鉴别诊断包括ventricular appendix，甲状舌管囊肿、粘膜下囊肿、脓肿或感染性喉气囊肿

This means it should do more damage against lightly armored or fully sundered targets but less damage against heavily armored targets.

这意味著，在无视护甲穿透等级的情况下，你能对轻甲目标能造成更多伤害，而面对护甲值高的目标你的伤害将有所降低。

When 3-benzoyl-5-formyl-indolizine or ethyl 5-benzoyl-indolizine-3-carboxylatewere used as substrates, a novel coupling reaction occurred, givinghydroxy-cycl[3,2,2]azines. A mechanism of the reaction was proposed.
