Chinese Journal of Behavioral Medicine and Brain Science 2009;18(11):1010-1012
Objective To investigate the difference of adiponectin( ADPN) levels in cerebral stroke and the relationship with inflammatory factors. Methods Using clinical, imaging, and laboratory data, 136 consecutive patients with acute cerebral infarction were categorized into three subtypes: large-artery atherosclerosis (LAA, n= 77) , small-artery atherosclerosis (SAA, re = 21) , cardioembolism (CE, n = 38). Patients of acute cerebral hemor-rhage(n = 39) were also included. Clinical features, levels of adiponectin, IL-10 and hsCRP were compared between groups. Results ADPN level of cerebral stroke group was lower than the control group(6. 3 ±2. 2 vs 8. 9 ± 2.7 mg/L). ADPN level differed by stroke subtype(F = 5. 21, P = 0. 005): highest in the CE group (8. 0 ± 1. 9 mg/L) and lowest in the LAA group(5. 5 ± 1. 0 mg/L). There was no significant difference between ischemic and hemorrhagic groups. ADPN level was relative to IL-10 ( r = 0. 274, P < 0. 01 ) and hs-CRP( r = -0. 308, P< 0. 05 ) . Conclusion Hypoadiponectinemia is associated with atherosclerosis and stroke. The variation of levels of ADPN and the inflammatory factors may contribute to the inflammation after ischemic stroke.

Journal of Guangzhou University of Traditional Chinese Medicine 2000;0(04):-
[Objective] To investigate the effect of Ruangan Kangxian Prescription (RKP), a prescription mainly composed of Radix Salviae Miltiorrhizae, Radix Paeoniae Rubra, Catechu, Radix Stephaniae Tetrandrae and Polyporus, for rats liver fibrosis induced by carbon tetrachloride (CC14) and to explore its mechanism. [Methods] Rats with liver fibrosis were induced by CC14 and were randomized to RKP group, normal group, Biejia Ruangan Tablet (BRT) group and model group. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), hyaluronic acid (HA), laminin (LN) , procollagen Ⅲ (PCⅢ ) were detected; hepatic histopathology and immunohistochemical result of transforming growth factor ?1 (TGF ?1 ) were also examined. [ Results ] Death rate of rats was reduced; serological parameters of hepatic function and liver fibrosis were improved and liver fibrosis showed by immunohistochemical method, HE staining and Masson staining was inhibited in RKP and BRT groups (P 0.05). [ Conclusion ] RKP and BRT have the similar effect in preventing CC14-induced liver fibrosis in rats and its mechanism may be related to the counteraction of expression of TGF ?1 .

Cilostazol increases the level of intracellular cyclic adenosine monophosphate (cAMP) by inhibiting cyclic nucleotide phosphodiesterase-3. Its main role was induced by the increased cAMP, including the inhibition of platelet aggregation, anti-thrombosis, vasodilation, and anti-endothelial cell proliferation. Recent experimental studies line indicated that cilostazol is promising in the intervention of acute cerebral ischemia and chronic cerebral hypoperfusion. Clinical trials have also demonstrated its efficacy. This article summarizes the pharmacological effect and mechanism of cilostazol, as well as its protective effect during ischemic stroke.

Objective To investigate the effect of therapeutic hypercapnia on the inflammatory response in the rat lung transplantation. Methods Male pathogen free Wistar rats weighing 300-400 g were used in this study. The animals were anesthetized with 3% pentobarbital sodium 30 mg/kg, tracheostomized and mechanically ventilated (V_T 10 ml/kg, RR 50 bpm, FiO_2 50%). Carotid artery and femoral vein were cannulated for BP monitoring, blood sampling and fluid and drug administration. Left lung transplantation was performed using modified cuff technique. Forty-eight animals in which lung transplantation was successfully performed were randomized into 2 groups ( n = 24 each) : model group (M) and hypercapnia group (H) . In group H, PaCO_2 was maintained at 80-100 mm Hg by inhalation of CO_2.Arterial blood samples were obtained before lung transplantation (To , baseline) and at 1, 2, 4 h (T_(1-3)) of reperfusion for determination of blood TNF-α, IL-1 and IL-8 concentrations. The animals were then killed and the transplanted lungs were removed for microscopic examination and calculation of wet/dry lung weight ratio. Results The MAP and PaO_2 were significantly higher in group H than in group M. The blood IL-8 and TNF-α concentrations were significantly lower at T_(1-3) in group H than in group M, but there was no significant difference in blood IL-1 concentration between the 2 groups. The elastase content in the lung tissue was significantly lower at T_2 and T_3 in group H than in group M. Microscopic examination showed that the alveolar hemorrhage, the infiltration of the lung by macrophages and neutrophils and lung edema were significantly less in group H than in group M. Conclusion Therapeutic hypercapnia can obviously inhibit the inflammatory response in the rat lung transplantation.
