This article aims at exploring ways of integrating subject of pathobiology under the guidance of scientific outlook on development and improving and enriching pathobiology inte-gration and construction through curriculum systems recombination and integration,teaching con-tents optimization to reflect the latest research progress,network education platform establish-ment,comprehensive and exploratory laboratory course teaching system construction,new syl-labus and teaching material making up.

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.

To fully incarnate"specialization"peculiarities of microbiology teaching courses by means of optimizing microbiology teaching contents and curriculum systems,and making up a new syllabus suitable to different specialties will lay a very solid foundation for cultivating medical talents with specialty traits.

Pathogen biology is a main course of curricula in medical university.In developing quality courses,we optimized Pathogen biology course content,created the PBL teaching mode suitable for this course,set up network teaching platform,enhanced teachers' qualification,constructed comprehensive and exploratory experiment teaching system,wrote new teaching syllabus and other measures,made the Pathogen biology course construction more reasonable and perfect.

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.
