AIM: To explore the mechanism of Nao-re-qing oral liquid (NRQ) decreasing endotoxin (ET)-induced fever in rabbits. METHODS: (1) The ET-induced fever model was established in rabbits. Febrile response of rabbits was observed. (2) The arginine vasopressin (AVP) content in the ventral septal area (VSA),and cAMP content in hypothalarmus (HP) and CSF were determined by radioimmunoassay.RESULTS: (1) In ET group,the maximal increment in body temperature (?T) [(1.80?0.16) ℃],6 h thermal respone index (TRI_6)(11.31?0.20),the cAMP content in the HP [(1.35?0.21)nmol/g],the cAMP content in CSF [(66.69?1.82) nmol/L] and AVP content in the VSA [(30.80?9.59)ng/g ] were significantly higher than those in NRQ+ET group[?T(0.82?0.08) ℃,TRI_6(5.73?0.09),HP: cAMP(0.70?0.50)nmol/g,CSF: cAMP(56.86?1.34),AVP:(11.91?3.47)ng/g]( P

AIM: To investigate the antipyretic mechanism of Naoreqing (NRQ) oral liquid, a Chinese medicine. METHODS: ① Fever models of rabbits were established by intravenous. injection of endogenous pyrogen (EP). ② The antipyretic action of NRQ were observed. ③ cAMP contents in the hypothalamus (HP) and the cerebrospinal fluid (CSF) were determined by radioimmunoassay. RESULTS: ① NRQ obviously reduced body temperature of febrile rabbits induced by EP (P

Objective To discuss the clinical results and surgical method in treatment of hypertensive intracerebral hemorrhage in basal ganglia. Methods From January 2007 to June 2013, the use of surgery treatment of hypertensive intracerebral hemorrhage in basal ganglia under direct vision assisted by the deep cold light suction in 104 cases,all the cases were done through lateral fissure-brain island approach,removing the hematoma with bipolar coagulation and hemostasis at sametime. This paper analyzed the group of patients with surgical methods and clinical efficacy. Results CT scan of intreatment group showed that there were 6 cases of secondary operation because of recurrent hemorrhage, and the hematoma-cleared rate>80% in 73 cases,50%-80% in 21 cases,<50% in 10 cases before operation within 6 hours. According to ADL classification,the 92 cases were alive after operation, good recovery in 65 cases, moderate disability in 22 cases, 5 cases of severe disability, death and give up treatment 12 cases. There was 12 cases of sec-ondary operation because of recurrent hemorrhage in control group, and the hematoma-cleared rate>80% in 16 cases,50%-80%in 23 cases,<50%in 24 cases before operation within 6 hours. According to ADL classification,the 45 cases were alive after operation in control group, good recovery in 14 cases,moderate disability in 16 cases,15 cases of se-vere disability,death and give up treatment 18 cases. There were significant differences between the two groups in op-eration time, intra-operative blood loss, the volume of blood transfusion, hematoma clearance rate, postoperative sur-vival rate and the survival quality ADL grading at half a year, and the indexes mentioned above in treatment group were better than those in control group. Conclusion Surgery treatment of hypertensive intracerebral hemorrhage in basal ganglia under direct vision by lateral fissure-brain island approach assisted by the deep cold light suction will shooter the operation time and lower the surgical injury,increase hematoma-cleared rate,it aslo has reliable hemostasis and more effective,so this method is worthy of clinical use.
