Objective To investigate the effect of Epimedium flavanoids (EF) on neuro-inflammatory reaction in Alzheimer disease (AD) mice model.Methods β-amyloid1-40 (Aβ1-40) was injected to the right lateral ventricle of 2-month-old male ICR mice to induce AD model. Morris water maze and step-through tests were used to measure the learning and memory ability of mice. The concentrations of interleukin-1β (IL-1β) and tumor necrosis factor α (TNF-α) in the hippocampus were determined by radioimmunoassay. The expression of glial fibrillary acidic protein (GFAP) positive cells (astrocytes) was detected by immunochemistry staining.Results Compared with the sham-operation group, the learning and memory ability decreased (P<0.05, P<0.01), the concentrations of IL-1β and TNF-α in the hippocampus increased (P<0.01) and the expression of astrocytes in the hippocampus elevated (P<0.05) in Aβ1-40 injection model mice. Intragastric administration of EF (100 and 300 mg/kg) for 3 weeks significantly improved the learning and memory ability (P<0.05, P<0.01), decreased IL-1β and TNF-α concentrations in the hippocampus (P<0.05, P<0.01) and inhibited the expression of astrocytes in the hippocampus (P<0.05), compared with Aβ1-40 injection model mice.Conclusion EF can decrease the inflammatory reaction in the brain of mice induced by Aβ.

Chinese Journal of Urology 2011;32(10):682-684
Objective To evaluate the clinical role of F-18 fluorodeoxyglucose (FDG)-positron emission tomography (PET) for the diagnosis and staging of prostate cancer.Methods 18F-FDG PET/CT and 99Tcm-MDP ECT whole body bone scan were both performed in 40 patients with prostate cancer proved by biopsy or surgery.We then evaluated the diagnostic value of 18F-FDG PET/CT for prostate cancer.Results Of 40 cases,17 cases were detected by 18 F-FDG PET/CT with a sensitivity of 42.5%.Of the 17 cases with lymphoma metastasis,8 cases were detected by CT while 15 cases were detected by 18F-FDG PET/CT.The sensitivity of 18F-FDG PET/CT is 88.2%.Though 18F-FDG PET/CT and 99Tcm-MDP bone scan have a similar sensitivity in detecting bone metastases,18 F-FDG PET/CT has better specificity and accuracy in detecting bone metastases than that of an 99Tcm-MDP bone scan.Conclusions Though the diagnostic value of 18F-FDG PET/CT in detecting primary focus of prostate is limited,it still has an important role in detecting lymph node metastases and bone metastases.18F-FDG PET/CT has its superiority in prostate cancer staging.It can also help clinicians to select the regimen of treatment.

ObjectiveTo discuss the effect of health education pathways in old patients undergoing laparoscopic cholecystectomy. Methods62 old patients undergoing iaparoscopic cholecystectomy were divided into the control group and the observation group, each group included 31 patients. The control group used the traditional method of health education, and the observation group adopted health education pathways. The satisfaction degree of patients with nursing and incidence of postoperative complication were compared between the two groups using χ2 test and t test. ResultsThe satisfaction degree of patients with nursing was higher and incidence of postoperative complication was lower in the observation group com-pared with those of the control group. ConclusionsHealth education clinical pathway can raise the edu-cation ability of nurses, increase the satisfaction degree of patients, reduce the complications and improve the serf- guard ability of the old people.

Objective To compare the therapeutic effects of two different intervention methods in the treatment of Navelbine leakage.Methods 40 cases with Navelbine leakage were collected and randomly divided into the control group and the observation group in equal number.Local block therapy in earlier period was used in the control group,and non-local block therapy was adopted in the observation group.Then the therapeutic effects of the two methods were compared.Results The differences of effect between the observation group and the control group were significant.Conclusions Local medicine injection in earlier period,wet compress and microwave physiotherapy after 24 hours is more effective than the local block in earlier period in the treatment of Navelbine leakage.It may shorten the time of pain and detumesccnce obviously,so it is worth popularizing clinically.

Objective To observe the effect of 2,3,5,4'-tetrahydroxy stilbene-2-?-D-glycoside (TSG)on learning and memory and free radicals metabolism in mice with dementia induced by ?-amyloid(A?).Methods The mice models were established by injection of A?1-40 into the right lateral ventricle,and the treatment group was administered with TSG for 8 weeks by gastrogavage.Morris water maze and step-through test were performed in all the mice and then the mice were killed and radioimmunoassay was used to detect the content of interleukin-6(IL-6).Results The learning and memory in model mice were worse and the cortical IL-6 content increased compared to the normal control mice.TSG improved the learning and memory of A?-induced model mice and reduced cortical IL-6 content.Conclusion TSG could improve the learning and memory of dementia mice and decrease cortical IL-6 content,indicating a promising prospect in the treatment of dementia disease such as Alzheimer's disease.

Chinese Journal of Rehabilitation Theory and Practice 2003;9(11):643-645
ObjectiveTo observe the effect of 2,3,5,4'-tetrahydroxy stilbene-2-β-D-glycoside(TSG) on learning and memory ability and free radicals metabolism in dementia model mice induced by β-amyloid (Aβ).MethodsAβ1-40 was given to the right lateral ventricle in the model group, and the TSG had been administered to the therapy group for 8 weeks by gastrogavage.All the mice of different groups were tested with Morris water maze and step-through test. Then the mice were killed and biochemical assays of neurol MDA,MAO-B,T-AOC were performed.ResultsThe model mice showed worse ability in learning and memory compared with control mice. The MDA cotent, MAO-B activity in the cortical increased in model mice compared with normal control; TSG reduced the MDA content, MAO-B activity,and increased T-AOC activity.ConclusionTSG can improve the learning and memory ability of model mice, decrease peroxidation level of brain, and increase antioxidation ability of brain, which suggest that TSG may have a promising application in treatment of dementia disease such as AD.

Objective To observe the effects of ultrashort wave diathermy on the expression of tumor necrosis factor-α (TNF-α) andBcl-2 in hippocampus, striatum and motor cortex of rats with cerebral ischemia/reperfusion. Methods The model of focal ischemia/reperfusionin Sprague-Dawley rats was induced with intraluminal middle cerebral artery occlusion (MCAO) with nylon monofilament suture. Therats were divided into 3 groups: sham group (n=6), model group (n=6) and ultrashort wave diathermy group (n=6). Brain tissue slices wereimmunohistochemically stained (SABC) to observe the expression of TNF-α and Bcl-2. Results The expression of TNF-α and Bcl-2 in lefthippocampus, striatum and motor cortex was higher in the model group than in the sham group (P<0.01). The expression of TNF-α was lowerbut Bcl-2 was higher in the ultrashort wave diathermy group than in the model group (P<0.05). Conclusion Ultrashort wave diathermycan affect the expression of TNF-α and Bcl-2, which may associate to the neuroprotection from focal cerebral ischemia/reperfusion injury.
