Limb-shaking transient ischemic attack (TIA), a rare manifestation, is commonly caused by severe stenosis or occlusion of an extracranial internal carotid artery. Such patients are usually treated with surgical revascularization or anti-platelet therapy. We present a 56-year-old woman with 6 months’ episodic attacks starting with mouth skewed to the right and a sensation of ‘weakness’ involving predominantly her left arm, and at times, also involved the left leg. This was immediately followed by rhythmic jerky movements of the left arm and at times, also involved the left leg. Magnetic resonance angiography revealed severe stenosis of M1 segment of the right middle cerebral artery. The patient’s symptoms were signifi cantly improved by treatment with anti-platelet drugs and nimodipine.

Objective To assess the efficacy of the mixtures of different concentrations of ropivacaine(R) and chloroprocaine(C)for epidural anesthesia in patients undergoing hysterectomy.Methods Sixty ASAⅠorⅡpatients aged 27-56 weighing 45-75 kg undergoing elective hysterectomy were randomly divided into 4 groups(n= 15 each);groupⅠ0.75% R alone;groupⅡ0.5% R-1% C;groupⅢ0.5% R-1.5% C and groupⅣ0.75% R+1% C.The epidural catheter was placed at L_(2,3)interspace and advanced 3.5 cm into the epidural space in cephalad direction.A total of 22 ml of epidural solution was injected in each group.The onset time,block height and duration of sensory block and the onset time,degree and duration of motor block(using Bromage scale)were assessed.The use of supplementary drugs(ketamine and ephedrine)and side effects were recorded.Results The onset time of sensory and motor block was significantly shorter in groupⅡ,ⅢandⅣthan in groupⅠ(0.75% R alone).The duration of sensory and motor block was significantly shorter in groupⅡandⅢthan in groupⅠandⅣ.The incidence of hypotension was significantly increased but the incidence of discomfort produced by traction on the viscera during operation was reduced in groupⅣas compared with groupⅠ.Conclusion The anesthetic efficacy of epidural 0.5% ropivacaine is significantly enhanced when mixed with 1.0% or 1.5% chloroprocaine.

The main results of the article are as follows:GS(10ug/ml,25ug/ml,50ug/ml)could augment NK activity of murine spleen cells in vitro(p

Objective To discuss the risk factors and clinical manifestation of coronary lesions in patients with premature coronary heart disease. Methods Coronary angiography was done in 415 coronary heart disease (CHD) patients. Patients were devided into two groups by age. One hundred and eighty patients with premature CHD (male≤55 years-old,female≤65 years-old) were compared with 235 patients with mature CHD to illustrate the risk factors of premature CHD and the clinical features of coronary lesions. Results The percentage of female patients was higher in patients with premature CHD(35.6% vs. 22.1%, P=0.003)and so were the history of dyslipidemia (74.4% vs. 55.7%, P

Objective To construct the expression plasmid of porcine leukemia inhibitory factor(LIF) in the prokaryotic system,and purify the expressed recombinant porcine LIF protein as antigen to immune rabbit for preparation of rabbit anti-pig LIF polyclonal antibody,and immunolocalize of LIF in pigs.Methods The cDNA fragment encoding mature porcine LIF protein was amplified by PCR,then cloned into the prokaryotic expression vector PET-31b at restriction sites NdeⅠand XhoⅠ.After transformed into E.coli BL21 for expression,the recombinant porcine LIF protein was purifed for preparation of anti-pig LIF polyclonal antibody as immunogen.Western blotting and ELISA were used to test the specificity and titer of the purifed IgG.Immunostaining was used to assay the expression of LIF in pigs.Results The constructed expression plasmid was identified by DNA sequencing and restriction enzyme digestion.The expression of the recombinant porcine LIF protein was performed exactly in E.coli BL21.By immuning the rabbit,the polyclonal antibody was successfully prepared.The results of ELISA and Western blotting showed that the antibody had high titer(1∶10000) and specificity.By immunostaining,LIF protein was faintly expressed in porcine myocardial cell,splenic cord and monolayer covering epithelium cell and pulmonary fibroblast.Conclusion The prepared polyclonal antibody has high titer and specificity;LIF has faint positive immunoreactivity in the normal porcine,myocardial cell,splenic cord and monolayer covering epithelium cell and pulmonary fibroblast.

With the development of internationalization of medical education,English-exclusive medical education has gradually been carried out to cultivate international medical students in many general medical colleges and universities.Analyzing the learning character of international medical students,paying attention to accumulation of practical public English and special English,using for reference all kinds of advanced experiences and forming own teaching style are the way to make good preparation for English-exclusive teaching for young teachers in general medical colleges and universities.
