Neoadjuvant chemotherapy is one of the common means in multidisciplinary treatment of locally advanced breast cancer,with anthracyclines and taxanes as main chemotherapeutic drugs.In recent years,molecular target agents have significantly improved the efficacy of chemotherapy,as well as have provided more choices and ideas for clinical treatment.Currently,the widely studied molecular targeted drugs include trastuzumab,lapatinib,pertuzumab,T-DM1 and bevacizumab.

Objective To explore the influence of ROI size on the diagnostic performance of shear wave elstography (SWE) of breast masses.Methods A total of 225 consecutive patients with 239 solid breast masses underwent SWE before surgery,and then quantitative SWE parameters,including the maximum stiffness (Emax),mean stiffness (Emean),ratio of stiffness of the mass to stiffness of surrounding fat (Eratio) and standard deviation (SD),were measured by two methods,one method was using larger ROI to include the largest part of a mass,and the other was placing fixed ROI=2 mm over the stiffest part of the lesion to measure.The diagnostic performance of the two methods were evaluated by ROC curve,and the cut-off value,sensitivity and specificity of each SWE parameter were obtained.Results There were no statistically significant differences between the performance of Emax,Emean and SD from the two different methods (all P＞ 0.05),the performance of Eratio of the two methods showed significant difference (P=0.046).The significantly higher specificity of Emax and Emean in the larger ROI were found,and the significantly higher sensitivity of SD and Eratio in the ROI=2 mm was found.Furthermore,the diagnostic performance of combination of SWE and BI-RADS were not greatly affected by the ROI size,the difference had no statistical significance (all P＞0.05).Conclusion The ROI size only affects the diagnostic performance of Eratio,and donot affect the diagnostic performance of the quantitative SWE parameters (Emax,Emean,SD) and combination of SWE and BI-RADS.

Objective To investigate the effects of endaravane on hypoxia-ischemia (HI)-induced brain injury in neonatal piglets. Methods Male piglets 3-7 days old weighing 2.0-3.0 kg were used in this study. Group Ⅰ 10 piglets were randomly collected as sham operation without HI. Twenty piglets with HI were randomly divided into 2 groups (n = 10 each) : group Ⅱ HI and group Ⅲ HI + endaravone. The animals were anesthetized with intraperitoneal pentobarbital sodium 50 mg/kg, tracheostomized and mechanically ventilated with 30% O_2. Right femoral artery and vein were cannulated. MAP, HR, PET CO_2, blood gases and glucose and rectal temperature were monitored. After 15 min stabilization cardiac arrest was induced by inhalation of hypoxic air (O_2 10%) for 40 min followed by inhalation of 21% O_2 for 5 min. The tracheal tube was then occluded for 7 min. Cardio-pulmonary resuscitation (CPR) was then started until recovery of spontaneous circulation (ROSC). CPR > 3 min was considered a failure. A bolus of endaravone 3 mg/kg was given iv over an hour at 30 min after CPR,followed by continuous infusion at 1.5 mg·kg~(-1)·h~(-1) for 5.5 h in group Ⅲ , while in group Ⅱ vehicle was given instead of endaravone. The neurological function of the animals was evaluated at 48, 72 and 96 h after ROSC and scored (0-154, 0 = normal, 154 = severest dysfunction). The animals were killed at 96 h after ROSC. The brains were removed for microscopic examination of striatum and cortex and determination of 8-hydroxy-2'-deoxyguanine (8-OHdG/OHG) expression in putamen by immuno-histochemistry. Results The neurological function scores were significantly higher at 48 h after ROSC and the number of viable neurons in striatum and sensory cortex were significantly lower and the expression of 8-OHdG/OHG in putamen was significantly higher in group Ⅱ than in group Ⅲ . Conclusion The antioxidant endaravone given after CPR can attenuate Hl-induced brain injury by inhibiting oxidative damage to DNA and RNA.

Protein kinase C (PKC) is a group of phospholipid-dependent serine/threonine protein kinases, which togeth-er with protein kinase A (PKA) and protein kinase G (PKG) constitute a superfamily of serine/threonine protein kinase AGC. PKC includes classic PKC, novel PKC, atypical PKC and some members of kinase associated with PKC (PRK). PKC is wide-ly distributed in mammalian tissues and cells, which plays an important biological role in growth and metabolism, prolifera-tion and differentiation of cells. A series of studies have demonstrated that variations of multiple cells, occurrence and devel-opment of diseases are related to the abnormal expression of PKC. Therefore, designing and searching for efficient PKC inhib-itors have very important implications for synthesis of many kinds of effective drugs and treatment of a variety of clinical dis-eases including cancer, cardiovascular, and hypertension, et al. In recent years, the research on PKC inhibitors has become the focus of domestic and foreign research. A large number of literatures have reported many kinds of effective PKC inhibi-tors, and analyzed their function site, mechanism, clinical trial data and so on. The discovery of these PKC inhibitors has im-portant implications for structural analysis of PKC and the treatment of diseases. So in this paper, the efficient PKC inhibi-tors are summarized.

[Summary] Glucagon-like peptide-1 ( GLP-1 ) agents play important roles in glycemic control in type 2 diabetes. Moreover, these agents also show various protective effects on cardiovascular system. GLP-1 agents improve vascular endothelial function, ameliorate the risk factors of cardiovascular disease including obesity, hyperglycemia, dyslipidemia and hypertension, delay the occurrence and progression of atherosclerosis, and protect against cardiac ischemia-reperfusion injury and heart failure. Therefore, GLP-1 agents may have beneficial effects on cardiovascular diseases at different stages and in multiple aspects.
