The gas remains perfect, its state equation remains always valid, except it will name in more calorically imperfect gas or gas at High Temperature. The goal of this research is to trace the profiles of the supersonic plug nozzle when this stagnation temperature is taken into account, lower than the threshold of dissociation of the molecules, by using the new formula of the Prandtl Meyer function, and to have for each exit Mach number, several nozzles shapes by changing the value of this temperature. A study on the error given by the PG （perfect gas） model compared to our model at high temperature is presented. The comparison is made with the case of a calorically perfect gas aiming to give a limit of application of this model. The application is for the air.展开更多

Methods A total of 216 rats were included in the experiment, of which 192 rats were randomly divided into four groups, including sham operation group（group A）, model group（group B）, governor vessel group（group C）, and conception vessel and governor vessel group（group D）, 48 rats in each group. The rats in each group were further divided into six sub-groups, including 12 h group, 24 h group, 48 h group, 72 h group, 96 h group and 144 h group. MCAO operation course was simulated in group A, and the common carotid artery, internal carotid artery and external carotid artery on the right side were exposed, without insertion of suture or treatment. After completion of modeling in group B, treatment was not conducted. After completion of modeling in group C, ＂Shuǐgōu（水沟 GV 26）＂, ＂Bǎihuì（百会 GV 20）＂ and ＂Dàzhuī（大椎 GV 14）＂ of governor vessel were selected, and electroacupuncture device was connected with ＂GV 14＂ and ＂GV 20＂. After completion of modeling in group D, ＂GV 26＂, ＂GV 20＂ and ＂GV 14＂ of governor vessel, and ＂Qìhǎi（气海 CV 6）＂, ＂Guānyuán（关元 CV 4）＂ and ＂Chéngjiāng（承浆 CV 24）＂ of conception vessel were selected; electroacupuncture device was connected with ＂GV 14＂ and ＂GV 20＂, ＂CV 4＂ and ＂CV 6＂. Neurological severity score was conducted.Enzyme linked immunosorbent assay（ELISA） was applied to determine the concentration of peripheral serum adrenocorticotropic hormone（ACTH） of rats, and immunohistochemical method was adopted to detect the expression levels of tumor necrosis factor α（TNF-α） and transforming growth factor β1（TGF-β1） in brain tissue of rats. The other 24 rats were also randomly divided into four groups mentioned above, 6 rats in each group, to detect cerebral ischemie volume. Results Compared with group B, the ischemia volume in brain tissue at 144 h after cerebral ischemia reperfusion decreased significantly in group C and group D（P〈0.05）, and the ischemia volume in group D was less than that in group C（P〈0.05）. The neurological impairment scores of group C and group D at all time points were lower than those of group B, and the differences were statistically significant（all P〈0.05）. The scores of group D at all time points were lower than those of group C, and the differences since 24 h were statistically significant（all P〈0.05）. Compared with group B, the excessive expression of ACTH was suppressed dynamically and generally in group C and group D（P〈0.05）; the expression level of TNF-α was down-regulated and TGF-β1 was up-regulated as well in group C and group D（P〈0.05）. The effect in group D was superior to that in group C. Conclusion Electroacupuncture at conception vessel and governor vessel can protect brain through the intervention of the expression of correlative signals of inflammatory response stress-injury-repair of cerebral ischemia reperfusion.展开更多
