ConclusionYinaotongluo Capsule can effectually improve enenery metabolism during cerebral ischemia and reperfuing, so that to reduce the neuronal dysfunction and death in infarcts at the late stage.

Panax ginseng C. A. Meyer (P. ginseng) has been used as traditional medicine in Asian countries for more than 2,000 years. P. ginseng contains many active components such as ginsenosides, peptides, essential oil and polysaccharides, among which, P. ginseng polysaccharides were reported to have immunomodulating, anti-cancer, anti-adhesive and antioxidant activities. For better understanding of the structures and biological activities of all the ginseng polysaccharides, here the recent research achievements were reviewed. This review would be helpful for the relevant researchers to get useful information.

Objective To investigate the effects of lipoxin A4 on store-operated calcium channel (SOC) and production of reactive oxygen species in macrophages induced by hpopolysaccharide (LPS).Method Macrophages were randomly assigned Io one of the following six groups:control group,LPS group,Thapsigargin group,lipoxin A4+LPS group,lipoxin A4+Thapsigargin group,2-Aminoethoxydiphenylborate+Thapsigargin group.The intracellular[Ca2+]iwas analyzed by eonfoeal laser microscopy.The production of reactive oxygen specips(ROS) was assayed by flow cytometry.Results LPS increased intracellular[Ca2+]i and reactive oxygen species in a dose-dependent manner.Lipoxin A4 suppressed approximately 75% of the Ca2+ ertry signal induced by thapsigargin and suppressed approximately 93% of the Ca2+ entry signal induced by LPS.The increase in intracellular[Ca2+]i was associated with increased ROS production which was abolished in the presence of lipoxin A4.Conclusions These findings indicate that the LPS-indueed intracellular[Ca2*]i increase depends on the Ca2+entry through SOC channel,and lipoxin A4 inhibits Ca2+ influx and ROS production through SOC channel in ratine maerophages induced by LPS.

Objective To investitate the efficacy of cannabinoid-2 receptor (CB2R) activation in preventing liver ischemia-reperfusion (I/R) injury in mice.Methods Forty-eight male C57BL/6J mice,weighing 20-30 g,were divided into 4 groups (n =12 each):sham operation group (group S),group I/R,CB2R agonist JWH133 group (group J),and CB2R agonist JWH133 + CB2R antagonist SR144528 group (group JS).Liver I/ R was produced by blocking the hepatic artery and portal vein for 30 min followed by 45 min of reperfusion in anesthetized mice.At 60 min before ischemia,JWH133 20 mg/kg was injected intraperitoneally in group J,and JWH133 20 mg/kg and SR144528 30 mg/kg were injected intraperitoneally in group JS.The liver was removed at 45 min of reperfusion for determination of tumor necrosis factor-α (TNF-α),macrophage inflammatory protein-1α (MIP-1α) and MIP-2 contents (using ELISA),and expression of TNF-α,MIP-1α,MIP-2 and intercellular adhesion molecule-1 (ICAM-1) mRNA (by RT-PCR) in the liver tissues and for microscopic examination of the pathological changes.Results Compared with group S,the contents of TNF-α,MIP-1α and MIP-2 were significantly increased,and the expression of TNF-α,MIP-1α,MIP-2 and ICAM-1 mRNA was up-regulated in J and JS groups.Compared with group I/R,the contents of TNF-α,MIP-1α and MIP-2 were significantly decreased,and the expression of TNF-α,MIP-1α,MIP-2 and ICAM-1 mRNA was down-regulated in J group,and no significant change was found in the parameters mentioned above in JS group.Compared with group J,the contents ofTNF-α,MIP-1α and MIP-2 were significantly increased,and the expression of TNF-α,MIP-1α,MIP-2 and ICAM-1 mRNA was up-regulated in JS group.The pathological changes of liver tissues were significantly attenuated in group J as compared with I/R and JS groups.Conclusion CB2R activation is effective in preventing liver I/R injury in mice and the mechanism is related to inhibitioni of inflammatory responses in liver tissues.

Objective To assess the feasibility of using PET molecular imaging to evaluate the therapeutic effects of traditional Chinese medicine FuZhiSan (FZS) on the model of aging Alzheimer's disease (AD) rats. Methods Twenty aged AD rats (Sparague-Dawley rats,male) were randomly divided into FZS treated group (n = 10) and control group (n = 10). Another 10 healthy adult rats were as blank controls. Morris water maze record system was used for cognitive function assessment. Before and after FZS treatment 18 F-fluorodeoxyglucose (FDG) and 11 C-2- [4'-(methylamino) phenyl] benzothiazol-6-ol ( PIB )PET imaging was undertaken. After post-treatment imaging procedures the brain tissues of all animals were taken for histochemical study,such as staining with HE,congo red,amyloid β (Aβ) immunofluorescence,5-bromo-2-deoxyuridine (BrdU) immunofluorescence and NeuN immunofluorescence. Paired t-test was performed with SPSS 13.0 software for the data analysis. Results The cognitive dysfunction of aging AD rats was improved after FZS treatment. The escape latency in FZS treated group was significantly shorter than that of control group ((32.5 ±10.8) s vs (102.6±8.8) s,t =15.7987,P=0. 0001). Diffuse neuronal loss and Aβ deposition were detected in the hippocampus and cortex in the aged AD rats. The imaging data showed that brain glucose metabolism was amended in FZS treated group while the abatement of amyloid deposition was not significant. Immunofluorescence results indicated that the neuronal proliferation was more remarkable in FZS treated group. Conclusions It may be feasible to use PET imaging as a method to evaluate the therapeutic effect in AD rats. FZS may ameliorate memory dysfunction of aged AD rats. Its mechanism may be partly contributed to the enhancement of the neuronal proliferation and survival.
