The Zheboshan gold deposit, which is located in the "Gold Triangle" area on the borders of Sichuan, Gansu and Shaanxi provinces, is a very complicated micro_fine disseminated gold deposit. Considering the ICP_MS measurements and Rb and Sr isotope data, it is suggested that the ore_forming materials may have come from the quartz_amphibole porphyrite dykes. It is also suggested that the age of ore deposit is generally consistent with the age of formation of the quartz_amphibole porphyrite. It is further deduced that the deposit is a magmatic hydrothermal ore deposit.

According to differential geometry and gear geometry, the equation of meshing for small teeth difference planetary gearing and a universal equation of conjugated profile are established based on cylindrical pin tooth and given motion. The correct meshing condition, contact line, contact ratio, calculating method for pin tooth's maximum contact point are developed. Investigation on the theory of conjugated meshing is carried out when the tooth difference numbers between pin wheel and cycloidal gear are 1, 2, 3 and ?1, respectively. A general method called enveloping method to generate hypocycloid and epicycloid is put forward. The correct meshing condition for cycloid pin wheel gearing is provided, and the contact line and the contact ratio are also discussed.

Hepatitis C virus(HCV) infects approximately 180 million people worldwide. Significant progress has been made since the establishment of in vitro HCV infection models in cells. However, the replication of HCV is complex and not completely understood. Here, we found that the expression of host prion protein(Pr P) was induced in an HCV replication cell model. We then showed that increased Pr P expression facilitated HCV genomic replication. Finally, we demonstrated that the KKRPK motif on the N-terminus of Pr P bound nucleic acids and facilitated HCV genomic replication. Our results provided important insights into how viruses may harness cellular protein to achieve propagation.
