Aim To further study the protective effects of acutobin on focal cerebral ischemia -reperfusion injury in rats. Methods Reversible middle cerebral artery occlusion (MCAO) models were produced by intraluminal suture technique, and reperfusion was begun 3 hours after occlusion and lasted 24 h. The extent of neurological deficits was evaluated by Longa' method; The cerebrovascular morphology was observed by electron microscope. The infarct area of brain was measured by 2,3,5-triphenyltetrazolium chloride (TTC) staining technique;The 2~4 U?kg~(-1) doses of Acutobin were administrated i.v. at the beginning of ischemia or reperfusion respectively. Results ① After 3-h occlusion and 24 h reperfusion, the neurological syndromes and the infarct area were showed, the change of cerebrovascular morphology were appeared and the ratio of TXB_2/6-Keto-PGF_(1?) in plasma was increased. ② After different doses of acutobin were administrated at different time respectively, the neurological syndromes were alleviated; the infarct areas of brain were diminished; the hurt of cerebrovascular endothelial cell was lessened and the ratios of TXB_2/6-Keto-PGF_(1?) in plasma were reduced. Conclusion Protective effects of acutobin on cerebral ischemia-reperfusion injury in rats may be related to lessening cerebrovascular injury and balancing the ratio of TXB_2/6-Keto-PGF_(1?)

Objective To evaluate the role of hippocampal AMPA receptors in the antidepressant effect of ketamine in rats.Methods Thirty male Wistar rats aged 2 months weighing 180-220 g were randomly divided into 3 groups (n =10 each):control group (group C); ketamine group (group K) and AMPA receptor antagonist NBQX group (group N).The animals were forced to swim for 15 min on the 1st day.On the 2nd day,NBQX 10 mg/kg was injected intrapefitoneally in group N; 30 min later,normal saline was injected intraperitoneally in group C,while ketamine 10 mg/kg was injected intraperitoneally in groups K and N.The forced swimming test was performed again for 5 min at 30 min after administration and the immobility time of the rats was recorded.Then the animals were sacrificed and the hippocampus was removed for determination of the expression of phosphorylated rapamycin (p-mTOR) and phosphorylated glutamate receptor 1 (p-GluR1).Results Compared with group C,the immobility time was significantly shortened and the expression of p-mTOR and p-GluR1 up-regulated in group K,and the immobility time was significantly shortened,the expression of p-mTOR up-regulated and the expression of p-GluR1 down-regulated in group N (P < 0.05).Compared with group K,the immobility time was significantly prolonged and the expression of p-mTOR and p-GluR1 down-regulated in group N (P < 0.05 ).Conclusion AMPA receptors in hippocampus are involved in the antidepressant effect of ketamine in rats and the inhibition of mTOR and GluR1 activities may be involved in the mechanism.

Objective To make nurses understand the essential factors of caring nursing service and satisfy the requirement of in-hospital patients. Methods To establish the plan of role-play test(RPT).The roles of patients were played by nurses. They experienced the caring requirement of patients, true feeling, the state of physiology and psychology, etc. Then we discuss and analyze the collected information to consummate measures of caring nufing service. Results The RPT deeped the nurses' understanding about essential factors of caring nursing service. The nursing quality and patients' satisfaction degree were improved compared with those of before(P<0.05).The nursing complaints and service quality were also increased. Conclusion Application of RPT proved to be an effective way to deepen the caring nursing service.

Objective To observe the change of brain iron content in deep gray nucleus using susceptibility weighted imaging (SWI) in patients with Parkinson's diseases (PD). Methods The SWI examination was performed in 40 PD patients (10 patients with Hoehn-Yahr stage Ⅰ , 9 patients with Hoehn-Yahr stage Ⅱ , 9 patients with Hoehn Yahr stage Ⅲ , 6 patients with Hoehn-Yahr stage Ⅳ, 6 ptients with Hoehn Yahr stage Ⅴ ) and 33 gender- and age- matched controls, after conventional brain magnetic resonance imaging examination on a 3.0T magnetic resonance imaging.The signal values of substantia nigra zona compacta (SNc), substantia nigra zona reticulate (SNr),red nucleus (RN), putamen (Pu), globus pallidus (GP) and caudate nucleus (CN) were assessed.Results Compared with the controls, the PD patients had statistically significance of signal value differences of SNc (P=0.002), SNr (P=0.043). RN (P= 0.003), Pu (P=0.023). GP (P=0.001) andCN (P=0.033). The more significant differences of SNc(P=0.001), SNr (P=0.010),RN (P<0. 001 ), Pu (P=0. 008), GP (P<0. 001) and CN (P=0. 011) were observed between more severe PD lesion and control. The signal values of SNc and GP showed obviously negative correlations with Hoehn-Yahr grading (SNcr=-0.943. P<0.001; GPr=-0.923, P<0.001). But there was weakly correlation of the signal values of SNr, RN, Pu, CN with Hoehn Yahr grading (SNr r=0. 496. P=0.001; RN r=-0. 480. P=0.002; Pu r=-0. 494, P=0.001; CN r=-0.471, P=0.002) Conclusions Measurement of the brain iron content of SNc and GP using SWI on MRI is a reliable means of diagnosing PD, and it has significant correlation with Hoehn-Yahr grading, It could evaluate the severity of PD.

Objective To explore the clinical characteristics,relationship between treatment and prognosis of sarcoidosis and relationship of relapse to prednisone.Methods The clinical data of 165 patients with sarcoidosis were collected.The clinical characteristics,treatment process and prognosis,relationship of relapse with prednisone maintenance dose and course of treatment were retrospective analyzed.Results Among them,the most common involved systems were lung and lymph nodes.The involvement rates of lung,extra-thorax lymph nodes,cutaneous,ocular,salivary glands,liver & spleen,kidney and nervous system was 87.3%,51.5%,6.7%,6.1%,6.1%,4.2%,1.2% and 1.2% respectively.Unilateral tonsil,breast,ovary and bone involvement was seen in only 1 patient respectively with an involvement rate of 0.6%.A retrospective analysis was made for 114 cases with complete follow-up data.The mean follow-up period was (11.7 ± 5.7) (5-32) years.And 46 cases had no symptom on routine medical examinations.The most common consulted departments were respiratory,dermatological and general surgery departments.Among 74 patients on prednisone,48 patients (64.9%) were cured while 13 patients (17.6%) relapsed.Whereas in the observation group,25/38 patients (65.8%) remitted spontaneously and only 1 patient (2.6%) had recurrence.Relapse occurred more often in prednisone therapy group than in observation group (P < 0.05).Longer prednisone 10-15 mg daily maintenance and a longer total course of treatment were associated with fewer recurrence(P < 0.05).Conclusions The clinical manifestations of sarcoidosis vary and many patients have a self-limiting course.The most common involved systems are lung and lymph nodes.Stage Ⅰ / Ⅱ disease should be observed before prednisone therapy.Prednisone 10-15 mg daily for at least 6 months and a total course of treatment over 18 months may prevent relapse.
