purpose To investigate the protective effect and character of dl-praeruptorin A(Pd-Ia)on focal cerebral ischemia in mice.Methods Transient focal cerebral ischemia in mice WaS induced by middle cerebral artery occlusion for 1.5 h.Pd-Ia was administered intraperitoneally either with multiple doses(1,5 and 10ms/ks)at 0.5 h before ischemia or single dose(5 ms/kg)at 0.5 h and 1 h before ischemic,the same time of ischemia,the same time of reperfusion,or 0.5 h and 1 h after reperfusion respectively.Neurological deficit score,infarct volume,brain edema,the activities of SOD and the contents of MDA were determined.Results Pretreatment with multiple doses(5 and 10 ms/ks)of Pd-Ia at 0.5 h before ischemia or single dose(5 mg/kg)of Pd-Ia at 0.5 h before ischemia,at the same time of ischemic,at the same time of reperfusion and 0.5 h after reperfusion significantly attenuated neurological deficit score,decreased infarct volume and alleviated brain edema,and the treatment at the time of reperfusion had the most marked effect.Pd-Ia(5 or 10 ms/ks)can significantly enhance the activities of SOD and lower the contents MDA.Conclusion dl-praeruptorin A has a neuroprotective effect on the injury in the acute phase of transient focal cerebral ischemia in mice,with optimal doses of 5 ms/ks and the optimal therapeutic time point of the same time of reperfusion.

Objective To study the clinical characteristic of non puerperal mastitis and estimate the effect of anti-mycobacterial agents for non puerperal mastitis .Methods 22 cases of periductal mastitis and gran-ulomatous mastitis receiving anti-mycobacteria drugs therapy from Mar .2012 to Mar.2014 were retrospectively analyzed.Results All patients were female.The mean age was 30 years(ranging from 24 to 46 years).The main clinical manifestation of the 22 patients were 18 patients(81.8%)with mass, 20 patients(90.9%)with abscess, 15 patients(68.2%)with fistula and 9 patients(40.9%)with all of the above 3 symptoms.6 patients had incision and drainage of abscess and 2 patients had tumor resection before anti-mycobacterial therapy .All of the 8 patients had postoperative recurrence .All patients underwent anti-mycobacterial therapy with 3 to 16 months.11 cases (50.0%)patients were cured without recurrence until now .7 cases(31.8%) patients were improved markedly and they still received drug treatment .2 cases(9.0%)patients with tumor size reduced to 2 cm were ready to sur-gical resection.2 cases(9.0%)were lost to follow-up.Conclusion Patients with refractory non puerperal masti-tis can be treated with anti-mycobacterial agents with relatively long treatment time and can also avoid mastecto-my.

Objective To explore the expression of BCSG 1 in the triple negative breast cancer and the non-triple-negative breast cancer and its significance .Methods The clinical data from 170 patients were retrospectively analyzed,which including 160 breast cancer and 10 benign breast disease .We checked the expression of BCSG 1 in the specimens by the immunohistochemistry to analysis the similarities and differences the BCSG 1 between the triple negative breast cancer and the non-triple negative breast cancer .Results The expression rate of the BCSG 1 was 41.0%in the non-triple negative breast cancer , which was lower than 57.5% in the triple negative breast cancer (χ2 =4.2,P=0.04).Conclusion The expression rate of the BCSG1 in the triple-negative breast cancer is higher than that in the non-triple-negative breast cancer.and it was statistically significant (P<0.05),so the expression of BCSG1 in triple negative breast cancer is unique .It prompt that BCSG1 can be a new treatment target in the triple negative breast cancer .
