湘南铜山岭矽卡岩铜铅锌矿床产于铜山岭岩体北东缘隐伏接触带及其外围地层中,在成因上与铜山岭花岗闪长斑岩密切相关。铜山岭铜铅锌矿床具有独特的成矿分带,从岩体向外依次发育近端内矽卡岩、近端外矽卡岩、硫化物-石英脉和远端矽卡岩矿体。根据穿切关系、交代结构和矿物组合等地质特征可以把铜山岭铜铅锌矿床划分为4个矿化蚀变阶段,从早到晚依次为进变质矽卡岩、退变质矽卡岩、石英-硫化物和碳酸盐阶段,其中石英-硫化物阶段为主成矿阶段。闪锌矿成分压力计研究表明,近端内矽卡岩型团块状硫化物矿石中闪锌矿的形成压力为(3.1±1.0)×10^(8) Pa,对应的成矿深度为6~12 km,相当于中—上地壳水平,说明铜山岭铜铅锌矿床形成于较大深度。近端内矽卡岩、近端外矽卡岩和远端矽卡岩中都存在两阶段绿泥石。绿泥石成分温度计研究表明,3类矽卡岩中退变质矽卡岩阶段绿泥石的形成温度分别为345~388℃、296~376℃和296~338℃,代表各类矽卡岩形成温度的下限;石英-硫化物阶段绿泥石的形成温度分别为270~318℃、209~238℃和200~223℃,代表各类矽卡岩矿体的成矿温度。3类矽卡岩的绿泥石温度表现出逐步降低的趋势,指示近端内矽卡岩、近端外矽卡岩和远端矽卡岩矿体依次形成。

Staphylococcal necrotizing pneumonia producing the Panton Valentine leukotoxin (PVl) has been described for many years. The french reference center for staphylococcal toxaemia defined it with precision in 1999. A 10- year- old child, died in 36 hours from respiratory distress and shock. Staphylococcal pneumonia was suspected then confirmed: S. Aureus producing PVl was isolated in lung, blood and articulations.

Vascular Ehlers-Danlos syndrome(EDS) is at high risk of death by arterial rupture. Case report. -A 13-year-old boy with vascular EDS and aortic dissection was admitted in pediatric emergency care unit. The children died after surgery by massive hemorrhage and prothetic rupture. Discussion. -The precocity of this vascular accident EDS is uncommon. It occured despite clinical and echocardiographic follow-up. The death of the children confirmed the difficulties in surgery of vascular manifestation, even if appropriate and rapid management was already done. Conclusion. -Patients with vascular EDS must be identified because of its lethal complications. Friability of the vessels makes surgical treatment difficult. A trial using beta blockers therapy is ongoing.

Breast cancer is the most frequent female malignancy worldwide. Current strategies in breast cancer therapy,including classical chemotherapy, hormone therapy, and targeted therapies, are usually associated with chemoresistance and serious adverse effects. Advances in our understanding of changes affecting the interactome in advanced and chemoresistant breast tumors have provided novel therapeutic targets, including, cyclin dependent kinases, mammalian target of rapamycin,Notch, Wnt and Shh. Inhibitors of these molecules recently entered clinical trials in mono- and combination therapy in metastatic and chemo-resistant breast cancers. Anticancer epigenetic drugs, mainly histone deacetylase inhibitors and DNA methyltransferase inhibitors, also entered clinical trials. Because of the complexity and heterogeneity of breast cancer, the future in therapy lies in the application of individualized tailored regimens. Emerging therapeutic targets and the implications for personalized-based therapy development in breast cancer are herein discussed.
