In this paper,a series of optically active MeO-BIPHEP-type ligands,（S）-6,6′-dimethoxy-2,2’-bis（di-p-alkoxyphenylphosphine）- 1,1′-biphenyl were synthesized and used to prepare the ruthenium *** effects of para-substituted were observed,the results showed that the ruthenium catalysts[diphosphine RuCl;diamine]containing both t-Bu and i-Pr substitutions have better activities and enantioselectivities than the non-substituted ruthenium catalysts in the asymmetric hydrogenation of acetophenone.

Chelation of 188Re to compounds such as MAG3 will further reduce the radiation dose to the patient in case of balloon rupture through the rapid excretion from the body. In order to prepare highly concentrated, carrier free 188Re-MAG3, Sbenzoyl mercaptoacetyltriglycine (S-Bz-MAG3) was synthesized, labeled with carrier free 188Re. The overall yield of S-Bz-MAG3 is higher than those published in theliterature. Dependence of the labeling yield of 1ssRe-MAG3 upon concentrations of reducing agent, pH, reaction time, etc. was examined and optimum conditions were confirmed. The concentration procedure was succeeded with Sep-Pak C18 cartridge to obtain highly concentrated 1s8Re-MAG3. In the case of optimun conditions, the labeling yield of 188Re-MAG3 was more than 98%. Radiochemical purity of 188ReMAG3 was more than 92% after 24 hour storage at room temperature.

Inheritance analysis and gene mapping of the glabrous trait were conducted using the crosses between a pubescent rice material Chuanxiang 29B （an aromatic elite maintainer line of hybrid rice）, and two glabrous rice materials, Lemont and R2 （R2 is a new restorer line of hybrid rice）. All F1 plants from the two crosses had pubescent leaves, confirming that the pubescence trait in Chuanxiang 29B is dominant over the glabrous trait. In F2 individuals, the segregation ratio of three pubescent to one glabrous plant suggests that a single glabrous gene was present in Lemont and R2. Using the bulked segregant analysis, the linkage analysis of the simple sequence repeat markers showed that the glabrous gene, gl-1, was flanked by GL311 and GL8 with the genetic distances of 0.19 and 0.92 cM on chromosome 5, respectively.

188Re labeled monoclonal antibodies are potential candidates for use in radioimmunotherapy. S-Bz-MAG3 as a bifunctional chelating agent was used for labeling of IgG with carrier free 188Re by pre-radiolabeling of the chelating approach. The conjugation conditions were optimized. The stability of 188Re-MAG3-IgG in vitro was high. The results may be useful to the studies of 188Re labeled MAbs for radioimmunotherapy.

A 34-year-old man admitted to our de- partment with complex blunt pancreaticoduodenal injury af- ter a car accident. The wall of the first, second, and third portions of the duodenum was extensively lacerated, and the pancreas was longitudinally transected along the supe- rior mesenteric vein-portal vein trunk. The pancreatic head and the uncinate process were devitalized and the distal common bile duct and the proximal main pancreatic duct were completely detached from the Vater ampulla. The length of the stump of distal common bile located at the cut surface of remnant pancreas was approximately 0.6 cm. A simplified Kausch-Whipple＇s procedure was performed after debride- ment of the devitalized pancreatic head and resection of the damaged duodenum in which the stump of distal common bile duct and the pancreatic remnant were embedded into the jejunal loop. Postoperative wound abscess appeared that eventually recovered by conservative treatment. Dur- ing 16 months follow-up the patient has been stable and healthy. A simplified pancreaticoduodenectomy is a safe alternative for the Whipple procedure in managing complex pancreaticoduodenal injury in a hemodynamically stable patient.

糖尿病视网膜病变(diabetic retinopathy,DR)是糖尿病的微血管和神经并发症,氧化应激是其重要致病机制。自噬是细胞在生理和病理条件下的一种重要调节活动,能够通过降解细胞内多余或损伤的蛋白质和细胞器维持细胞内环境稳态。研究表明,自噬和氧化应激之间具有重要联系,本文从DR早期微血管病变、DR神经病变和DR其它病变等方面综述自噬与氧化应激的具体关系,以期为阐明DR发病机制提供新的思路。
