CT长骨测量在骨折髓内钉固定术中的应用

目的：探讨CT在长骨测量中的应用价值.方法：经X线检查证实的肱骨、股骨、胫骨骨折患者600多例，其中302例临床行髓内钉固定术，并在术前进行了健侧骨的CT定位扫描，测量其两点之间骨干长度及骨髓腔最窄处的宽度。结果 依据术前CT定位测量数据而选择的髓内钉在手术中完全适用。结论：此方法操作简便测量数据准确为临床提供可靠依据。     

Temperature trends in Japan: 1900–1996

Summary ?Long-term trends in annual, seasonal, and monthly mean temperature (abbreviated as AMT, SMT, MMT, respectively) in Japan are investigated. The magnitude of a trend is measured by assuming it to be linear. The statistical significance of a site trend is assessed by the Mann-Kendall (MK) with consideration of serial correlation. The statistical field significance of trends in three major climatic regions: Hokkaido (I), areas adjacent to the Japan sea (II), and to the Pacific Ocean (III), is evaluated by the bootstrapping test which preserves cross-correlation among sites. From 1900 to 1996, AMT increased from 0.51 to 2.77 °C averaged across all 46 sites. At the regional scale, AMT increased by 1.38, 1.08, and 1.32 °C in regions I, II, and III, respectively. The trends at both sites and regions are statistically significant even at the significance level (α) of 0.005. SMT increased from 0.47 to 3.69 °C at all the 19 available sites with the highest increases in winter and spring. Except for a few series, the changes in SMT are statistically significant at α = 0.01. The upward trends in SMT are statistically significant even at α = 0.001 in both regions II and III. MMT at 19 sites increased within a wide range from 0.17 to 4.12 °C. The increases are largest in the winter and spring months, and most of the site increases are statistically significant at α = 0.05. The trends are statistically significant at α = 0.025 and 0.001 in regions II and III, respectively. The trends in both SMT and MMT in region III are larger than those in region II.
