The latter is hydrolysed via 2,4-dichloro-5-fluoro-3-dichloromethylbenzoic acid, which can be isolated if necessary, to give 2,4-dichloro-5-fluoro-3-formyl-benzoic acid, the aldehyde group of which is reacted to give 2,4-dichloro-5-fluoro-3-N-hydroxyiminomethyl-benzoic acid, from which, with simultaneous conversion of the carboxyl group into the chlorocarbonyl group, water is eliminated using an acid chloride to give the nitrile 2,4-dichloro-3-cyano-5-fluoro-benzoyl chloride.

随后，在游离基条件下进行侧链的氯化，得到2，4-二氯-5-氟-3-二氯甲基-1-三氯甲基苯、后者被水解，经过2，4-二氯-5-氟-3-二氯甲基苯甲酸(如果需要此化合物可以分离)，得到2，4-二氯-5-氟-3-甲酰苯甲酸，将其醛基反应，得到2，4-二氯-5-氟-3-N-羟基亚氨基甲基苯甲酸，用酰氯从其中除去水，同时将羧基转化为碳酰氯，得到一种腈，即2，4-二氯-3-氰基-5-氯-苯甲酰氯。

Next we obtain some group theoretic conditions for the existence of p-blocks with defect 0 in some special groups, for instance, in an extension group of a nilpotent group by a abelian group, in a p-nilpotent group, in a group with all subgroups of order p are conjugate, and so on.

其次我们给出了一些特殊群的亏零块存在的群论条件，如幂零群被交换群扩张的群，p—幂零群，p—阶子群均共轭的群等。

Results EA group anaesthetize effect is slightly inferior than other two group,CSEA group and OCSEA group anaesthetize plane are more easy controlled than EA group,OCSEA group circulate is more stabilization than other two groups.

结果 硬膜外麻醉组的麻醉效果略差于另2组，CSEA组和OCSEA组的麻醉平面比EA组更易控制，OCSEA组的循环比其它2组更稳定。

Methods:All of 40 male Sprague-Dawley rats were divided into 3 groups:control group（group A, n = 10）, diabetic group for 4 weeks（group B, n = 14）, and diabetic group for 12 weeks（group C, n = 16）. The diabetes model was established by the injection of STZ. After some weeks erection function was examined by apomorphine injection. The content of NF-κB in the erectile tissue was evaluated by immunohistochemistry staining. At the same time the activity of NF-κB was detected by electrophoretic mobility shift assay.

M{rX*o0 OBJECTIVE: To investigate the effects of neuronal nitric oxide synthase inhibitor 7-nitroindazole (7-NI) on smoke inhalation pulmonary injury in rats. METHODS: Forty healthy male SD rats were randomly divided into three groups: control group (n=8), smoke inhalation model group (n=16) and 7-NI treatment group (n=16). After reproducing the smoke inhalation model, to the 7-NI treatment group rats 7-NI (20 mg/kg in 2 ml arachis oil) was administered by intraperitoneal injection, while in the control group and the model group, 2 ml arachis oil was administered by intraperitoneal injection.
