Aim To investigate the effect of fenofibrate on focal cerebral ischemia injury in rats and its mechanism.Methods The rat model of global cerebral ischemia/reperfusion injury was established by bilateral common carotid arteries occlusion combined with hemorrhagic hypotension.Fenofibrate (33, 100, 300 mg·kg~(-1)) was intragastriclly administered 30 min before the operation, MK886 (6 mg·kg~(-1)) was given intraperitoneally 30 min before administration of fenofibrate (300 mg·kg~(-1)).Morris water maze was used to evaluate the ability of spatial learning and memory function.HE staining was used to observe pathological morphological changes of hippocampal neurons. NF-κBp65 expression was detected by immunohistochemistry, SOD activities and MDA contents were analyzed by biochemistry, and IL-1β, IL-6, IL-10, TNF-α levels were detected by ELISA.Results Fenofibrate remarkably improved the spatial learning and memory function, obviously prevented the hippocampal neurons from karyopycnosis and losing induced by I/R. Fenofibrate significantly blunted the increase of MDA, NF-κBp65, TNF-α, IL-1β, IL-6, and the decrease of IL-10 and SOD activities of I/R rats.Conclusions Fenofibrate has an obviously neuroprotective effect on global cerebral ischemia/reperfusion damage by activating PPARα.The anti-inflammation and antioxidative stress of fenofibrate may be involved in the protective mechanism.

100 were found in 8,7 and 9 patients respectively.(3)The positive rate in detection of insulinoma by ultrasonography,CT scan and intraoperative palpation was 30%,60% and 100% respectively.Conclusion Typical symptoms and laboratory examinations are main evidence in diagnosis of insulinoma.Intraoperative ultrasound and palpation are more useful for localization diagnosis of insulinoma.Operations should be considered in patients with typical clinical characteristic and negative imageology.

Objective To explore the effects of YOGA relaxation on anxiety and somatic symptoms in patients with depression. Methods 60 inpatients with depression were ctegorized into the control group and the observation group with 30 cases in each group. HAMD scale were scored before and after medication (2,4,8 weeks). Results Before medication, there was no statistical differenoe between two groups in HAMD total score and subscores, but the difference was obvious in anxiety and somatic, sleep disturbance and hopelessness subscore at the end of the second and 4th week. Conclusions YOGA relaxation can improve anxiety emotion and somatic symptoms, enhance sleep quality in patients with depression.

Aim To study the protective effect of caffeic acid on brain damage induced by chronic aluminum overload in rats.Methods The brain injury model of rats was established via intragastric administration of aluminum gluconate(element aluminum 200 mg?kg-1) once a day,5 d a week for 20 weeks.The 5-LO inhibitor caffeic acid(30 mg?kg-1,10 mg?kg-1) was intragastrically administered 1 h after aluminum administration.Pathomorphological changes of hippocampal neuron and the spatial learning and memory function were observed.The MAO-B,AChE and SOD activities,and the MDA contents of brain tissue in rats were measured.Results Chronic aluminum overload could markedly induce spatial learning and memory function impairment,and hippocampal neuronal injury in rats.The MAO-B and AChE activities,and the MDA content significantly increased,while SOD activities significantly decreased in chronic aluminum overload rats.The administration of the caffeic acid can significantly prevent rats from learning and memory function impairments and hippocampal neuronal death,and blunted the decrease of SOD activities and increased MDA contents induced by chronic aluminum overload in rats.Caffeic acid also obviously decreased the MAO-B activities and AChE activities of chronic aluminum overload rats.Conclusion Administration of caffeic acid can prevent the rat brain from damage induced by chronic aluminum overload.

Objective To understand the epidemiological status of chronic diseases and its related risk factors among adult residents in Hebei province.Methods A total of 4 200 adults from 20 districts in Hebei province were selected by multistage stratified random sampling method,and they were investigated with questionnaire,and the body measurement and blood sample were analyzed.Results The prevalent rates of overweight,obesity,central obesity,hypertension,dyslipidemia and diabetes mellitus were 35.19%,16.38%,52.98%,38.50%,39.62% and 5.81%,respectively.The age-adjusted rates were 30.28%,14.05%,44.32%,27.86%,32.71% and 4.00%,respectively.The prevalence of chronic diseases was highly associated with age.The prevalence of chronic diseases in male was higher than that in female among people aged under 55 yrs,but lower among people aged over 55 yrs.The rates were higher in urban areas than in rural areas.The prevalence rates of cigarette smoking and alcohol-drinking in male were higher than in female(P

Objective To clarify insulin resistances and pancreatic ?-cell hypofunctions in cases with different glucose tolerance. Methods 5523 Chinese underwent OGTT and were classified into normal glucose tolerance (NGT), isolated impaired fasting glucose (IFG), isolated impaired glucose tolerance (IGT), IFG with IGT (IFG+IGT) and type 2 diabetes mellitus (T2DM) groups based on OGTT results. HOMA-IR, HOMA-?△I30/△G30and AUCI of different groups were statistically analyzed by SPSS12.0. Results Compared to NGT group, HOMA-IR was increased by 41%, 19%, 47% and 69% respectively in IFG, IGT, IFG+IGT and T2DM groups (all P

Objective To study the neurotoxicity of chronic aluminum overload and the protective effects of nimodipine in rats.Methods The brain damage models of rats were established via intragastric administration of aluminum gluconate(element aluminum 400 mg/kg)once a day,5 d/week for 12 weeks.The step-down test and programmed Morris water maze test were used to evaluate the changes of learning and memory functions of rats.Pathomorphological changes of hippocampi of rats were observed.The activities of SOD,ChAT,AchE,MAO-B and the contents of MDA of brain tissue in rats were also measured.Nimodipine(80 mg/kg)were intragastrically administered 4 h after aluminum administration every time for 12 weeks.Results Chronic aluminum administration induced the impairment of avoidance learning and memory ability and spatial oriental ability.Consistent with the behavioral changes,neuronal death in the hippocampi,decreased activities of SOD and ChAT,increased content of MDA,and increased activity of MAO-B and AchE were detected in the aluminum-overload mice.The administration of nimodipine could significantly protect rats from the brain damage,and behavioral and biochemical changes above caused by aluminum overload were in a dose-dependent manner.Conclusion These results suggest that changes of cellular calcium overload and oxide stress and MAO-B activities are involved in pathophysiological mechanisms of brain injury induced by chronic aluminum overload.Nimodipine has a protective effect on neurotoxicity of chronic aluminum overload.

Objective To observe the effects of the third-stage community-based rehabilitation program on functional recovery of stroke patients with hemiplegia. Methods 158 stroke patients with hemiplegia were divided into rehabilitation group and control group. Besides normal medicine and first-stage institution-based rehabilitation similar with that of control, rehabilitation group received a standardized third-stage community-based rehabilitation. They were assessed with the National Institutes of Health Stroke Scale (NIHSS), Fugl-Meyer Assessment (FMA), Modified Barthel Index (MBI) and Modified Rankin Scale (MRS) before, 1 month and 6 months after treatment. Results The scores of the FMA and the MBI of the rehabilitation group were higher than that of the control group (P<0.01), while were lower of the NIHSS and MRS in the rehabilitation group than in the control group at the end of the sixth month (P<0.01). Conclusion The third-stage community-based rehabilitation may improve the recovery of the stroke patients with hemiplegia.

OBJECTIVE:To provide reference for rational use of second class of psychotropic drugs in the clinic. METHODS:The second class of psychotropic drugs in outpatient department of our hospital during 2012-2015 were analyzed retrospectively in respects of the number of common drugs prescription,distribution of gender/age/disease diagnosis,DDDs and DUI,etc. RE-SULTS:During 2012-2015,second class of psychotropic drugs in outpatient department of our hospital accounted for 25.09%of to-tal prescription amout. The drugs with high use frequency were alprazolam,clonazepam,lorazepam and estazolam,accounting for 93.10% of total prescription amount of second class of psychotropic drugs. The proportion of male to female was 1∶1.50;the pa-tients aged 19-35 years old took up the biggest proportion,accounting for 34.62%. The proportion of schizophrenia prescription was the highest,accounting for 45.17%. DDDs of alprazolam was the highest,being 742 141.67;its DUI was 1.075;DUI of oth-er drugs was lower than 1.0. CONCLUSIONS:The use of second class of psychotropic drugs is basically reasonable in our hospi-tal. Guiding principles of Clinical Application of Psychotropic Drugs should be implemented strictly and continously to avoid abuse of second class of psychotropic drugs.
