Coronary fistulae and ventricular septal perforation are very rare clinically, and even less caused by cardiac leiomyosarcoma. A case is reported that a 67-year-old female had cardiac leiomyosarcoma with progressive heart failure and coronary fistulae and ventricular septal perforation. This case was special since all ante-mortem examinations and cardiac surgery failed to detect the presence of any abnormal car-diac mass. Therefore, the malignant cardiac tumors could appear in an invasive form without mass and be one of the causes of the coronary fistulae and ventricular septal perforation.

A new type Ni-P hollow material with rod-shape is prepared by electroless deposition method and heat treatment based on the shape of Nocadia, a kind of bacteria. The material is characterized and its magnetic, electromagnetic and mechanical properties are measured. It is found that the Ni-P coating transforms from a disordered structure before hollowing to an ordered arrangement of face centered cubic (FCC) Ni after hollowing at 673 K and body centered tetragonal Ni3P occurs. After hollowing no change of the surface morphology has been found. But the cytoplasm disappears and the Ni-P layer becomes more compact. A new type hollow material with shell thickness of 150―200 nm is obtained. The saturation magnetization (Ms), remanent magnetization (Mr) and coercivity (Hc) are enhanced to 20 emu/g, 2.7 emu/g and 117.5 Oe, respectively. The dielectric and magnetic loss are improved to 14 and 0.4, respectively. The hardness and the elastic modulus are raised to 1.80 GPa and 23.79 GPa, respectively. All show great improvement compared with those before hollowing.

Development of transition metal-based photocatalysts with low cost, strong visible light absorption, and high efficiency is a longstand pursuit for advanced organic synthesis, yet remains highly challenging. In this article, an anthraquinone-based copper(I)cyclic trinuclear complex(1) was designed and it featured strong visible light absorption, high charge separation efficiency and photochemical properties. Complex 1 as a heterogeneous photocatalyst can efficiently catalyze homo-coupling of terminal alkynes and denitrification-oxidative coupling reaction between hydrazinopyridine and terminal alkynes with excellent yield(up to 99%), broad substrate tolerance(27 examples) and superior reusability(up to 10 cycles without loss of performance) under mild conditions.

The selectivity of short circuit protection of high voltage lines in coal mines cannot be realized by existing protection systems. To solve this problem, a scheme based on double layer Ether CAT and optical fiber interlock net was proposed. The system is mainly composed of double layer Ether CAT, optical fiber interlock net, ground monitoring station, underground control stations and integrated protection devices with Ether CAT communication interface and interlock interface. Double layer Ether CAT and optical fiber interlock net cooperate with each other, when one is interrupted, the other net carl realize selectivity of short circuit protection independently, Results of test show that the system can achieve selectivity of short circuit protection reliably, determine the fault location quickly, shorten troubleshooting time and improve safety and reliability of the power network in coal mines.
