（ E）-5,5＇-Bis（ 5-（ benzo[ b ]thiophen- 2-yl ）thiophen-2-yl ）-1,1＇-bis（ 2-ethylhexyl ）-[ 3,3＇-bipyrrolylidene ]- 2,2＇（1H, l＇H）-dione （BTBPD） has been reported by Zhang and co-workers. To further understand the charge-transporting nature of BTBPD, the density-functional theory （DFF） and the Marcus charge transfer theory were performed. The character of the frontier molecular orbitals, reorganization energies and transfer integrals in different directions were considered in details. The results revealed that the BTBPD has high hole transport efficiency （μ = 0.29 cm2 V-1 s-1 ）. The intermolecular π-π interaction and S...S interaction provide the holes transport channels.

BACKGROUND Upper gastrointestinal bleeding(UGIB) after an acute myocardial infarction(AMI) is not an uncommon complication. Acute UGIB caused by Mallory-Weiss syndrome(MWS) is usually a dire situation with massive bleeding and hemodynamic instability. Acute UGIB caused by MWS after an AMI has not been previously *** SUMMARY A 57-year-old man with acute inferior wall ST elevation myocardial infarction underwent a primary coronary intervention of the acutely occluded right coronary artery. Six hours after the intervention, the patient had a severe UGIB,followed by vomiting. His hemoglobin level dropped from 15.3 g/d L to 9.7 g/d L. In addition to blood transfusion and a gastric acid inhibition treatment,early endoscopy was employed and MWS was diagnosed. Bleeding was stopped by endoscopic placement of titanium *** Bleeding complications after stent implantation can pose a dilemma. MWS is a rare but severe cause of acute UGIB after an AMI that requires an early endoscopic diagnosis and a hemoclip intervention to stop bleeding.

The ecological environment in the area where the Qinghai-Tibet Railway passes through is very fragile and is showing the tendency of retrogression. So as the construction would largely disturb the earth surface and vegetation and would have a large quantity of earth and stone digging, the construction of the railway in this area would certainly lead to a series of questions. Through the integrated analysis of the actualities of soil erosion and water and soil conservation along the section of Tanggula-Lhasa of the Qinghai-Tibet Railway, and with the combination of the features of the railway construction and the environment, the protection measures and proposals about the soil erosion along the section of Tanggula to Lhasa of the Qinghai-Tibet Railway have been put forward, so as to reach to the purpose of holding back the further development of soil erosion along the line, improving the ecological environment in the local area and maintaining the railway in normal operation.
