The Tongshi magmatic complex comprises fine-grained porphyritic diorite and syenitic porphyry. Eighteen analyses for fine-grained porphyritic diorite gave two concordia ages, in which ten analyses constitute the young age group, giving ^206Pb/^238U ages ranging from 167.9 Ma to 183 Ma with a weighted mean age of 175.7±3.8 Ma, and the other eight yielded ^207Pb/^206Pb ages of 2502 Ma to 2554 Ma with a weighted mean 2518±11 Ma. Two analyses for syenitic porphyry gave ages of 2485 Ma and 2512 Ma, respectively. The age of 175.7±3.8 Ma indicates that the crystallization of the Tongshi magmatic complex occurred in the Middle Jurassic, whereas that of 2518±11 Ma is interpreted as the age of inherited magmatic zircons in the Neoarchean Wutai period.展开更多

METHODS:The study evaluated all patients with colorectal cancer referred to either general surgical units or a colorectal unit from 1/1996 to 6/2001.These results were compared to a historical control group treated within general surgical units at the same hospital from 1/1989 to 12/1994.A Kaplan- Meier survival analysis compared the overall survivals (all- cause mortality) between the groups.A Cox proportional hazards model was used to determine the influence of a number of independent variables on survival.These variables included age,ASA score,disease stage,emergency surgery, adjuvant chemotherapy and/or radiotherapy,disease location,and surgical unit. RESULTS:There were 974 patients involved in this study. There were no significant differences in the demographic details for thethree groups.Patients in the colorectal group were more likely to have rectal cancer and Stage Ⅰ cancers, and less likely to have Stage Ⅱ cancers.Patients treated in the colorectal group had a significantly higher overall 5-year survival when compared with the general surgical group and the historical control group (56 % versus 45 % and 40 % respectively,P<0.01).Survival regression analysis identified age,ASA score,disease stage,adjuvant chemotherapy,and treatment in a colorectal unit (Hazards ratio:0.67;95 % CI:0.53 to 0.84,P =0.0005),as significant independent predictors of survival. CONCLUSION:The results suggest that there may be a survival advantage for patients with colon and rectal cancers being treated within a specialist colorectal surgical unit.展开更多
