The author reviewed some researches on teacher's work related stress in China and abroad. The present researches mainly focus on the sources of stress in teachers' work life. Some practices of work related stress in USA and Chinese special education field were discussed in the article. In the end, the author took a perspective on future research of teacher's work related stress in Chinese special education field.

0.05).Conclusion MSCs could derive to cardiomyocyte-like cells after induction and incubation for 4 weeks in vitro,of which Ca~(2+)/CaMKⅡ is similar to the normal cardiomyocytes cells.

OBJECTIVE To investigate the clinical distribution and antibiotics resistance of Pseudomonas aeruginosa nosocomial infection after open-heart operation.METHODS The clinical data of 393 patients with nosocomial infection from Jan 2004 to Dec 2007 were analyzed retrospectively.RESULTS There were 57 infected cases caused by P.aeruginosa,and accounted for 14.5% of all infections during period.All infected patients had serious original heart diseases,and received broad-spectrum antibiotic therapy previously.Forty-two patients developed postoperative cardiorespiratory function failure,and 28 patients needed circulatory support.Thirty-six patients prolonged mechanical ventilation time for over 1 week.Results of susceptibility test showed that ciprofloxacin,levofloxacin and piperacillin/tazobactam were the most active antibiotics,followed by tobramycin,netilmicin,gentamicin,meropenem and imipenem/cilastatin.P.aeruginosa presented high resistance to ceftazidime and cefoperazone/sulbactam.CONCLUSIONS P.aeruginosa is one of the most common pathogenic bacteria after open-heart operations in our hospital and presented multidrug resistance.Rational use of antibiotics is important to reduce drug resistant strains.

Molecular markers have been widely used in the treatment of breast cancer. Cell proliferation markers Ki-67 antigen representing breast neoplasms proliferative activity is associated with clinic pathological features and prognosis and has an important predictive value in assessing the effect of neoadjuvant chemotherapy and endocrine therapy. High expression of Ki-67 is a bad prognostic factor of breast cancer, which is highly related to tumor progression, metastasis and prognosis.

Objective To explore the effects of simvastatin in the treatment of hyperlipidemia fatty liver. Methods Animal models were set up by feeding high caloric diet. Liver index (liver weight/body weight), liver function, blood lipid, liver lipid, the content of MDA in serum and liver were assayed before and after therapy with simvastatin. Results Liver index, blood lipid, liver lipid, and the content of MDA in liver as well as in serum increased significantly ( P

Objective To observe the behavior changes and connexin 32(CX32),connexin 43(CX43)expressions in hippocampus and the effect of carbenoxolone on their expression in epileptic immature rats induced by lithium-pilocarpine.Methods Seventy-two SD immature rats of 21 d were randomly divided into control group(n=24),lithium-pilocarpine kindled group(n=24)and carbenoxolone treated group(n=24),each group by 24 h,3 d,7 d and 30 d were subdivided into 4 groups(n=6).Immuno-histochemisty was used to observe the expressions of CX32 and CX43 in hippocampus areas of immature rats,and to observe their behavior changes.Results The scores of the severe elileptiform seizures(Racine Ⅳ/Ⅴlevel)in lithium-pilocarpine group were significantly higher than those in carbenoxolone treated group;The latency in carbenoxolone treated group was prolonged significantly(P

Objective To explore the change rule and clinical application value of hemorheologic indexes in patients with acute intracerebral hemorrhage ( ICH) . Methods The hemorheology indexes of 100 acute ICH patients ( ICH group) were detected within 24 h, and compared with 30 normal controls ( normal control group) . The effect of hemorheology index on history of hypertension, hemorrhage quantity and the hemorrhage location were analyzed. Results Compared with those in normal control group, the indexes of whole blood viscosity, plasma viscosity and erythrocyte sedimentation rate were significantly increased and erythrocyte aggregation index, erythrocyte deformability index and hematocrit were significantly decreased in acute stage ( all P< 0. 01 ) . Blood rheology indexes were changed significantly in hypertensive cerebral hemorrhage group (all P<0. 01), the whole blood viscosity (200 s-1 and 50 s-1 ) , erythrocyte aggregation index, hematocrit and erythrocyte sedimentation rate in non-hypertensive cerebral hemorrhage group were changed significantly ( P< 0. 05 - 0. 01 ). Compared with normal the non-hypertensive cerebral hemorrhage group, the whole blood rheology indexes except erythroate sedicmnt ation rate significantly erythrocyte sedimentation rate were significantly changed ( P< 0. 05 ) . As the hemorrhage quantity increased in each groups, the whole blood viscosity ( 200 s-1 and 50 s-1 ) and plasma viscosity of cerebral hemorrhage patients were significantly increased, otherwise the erythrocyte aggregation index was significantly decreased (P<0. 05-0. 01). There were statistical differences compared the indexes of whole blood viscosity (200 s-1 and 1 s-1 ) , plasma viscosity, erythrocyte aggregation index and erythrocyte sedimentation rate among each groups of different hemorrhage locations in acute ICH patients (all P<0. 05). Conclusions The blood of acute ICH patients shows a state of concentrated, sticky, aggregation and coagulation that severely affects the prognosis. The patients with hypertension and greater hematoma changed obviously, different hemorrhage location affected differently.
