There are three diwa regions in South Siberia and West Mongolia. One of them is arranged in West Transbaikalia and was formed from Devonian till Carboniferous periods. Numerous deposits of tungsten , tin, molybdenum, REE, synnyrites, urtites are genetically linked with intrusive rocks. The next diwa region is arranged in North Mongolia and South Buryatia. This diwa region was formed in the Late Paleozoic time. The deposits of molybdenum, tungsten, boron, iron, copper, beryllium are genetically linked with magmatic rocks of this region. The third region was formed in Devonian in West Mongollia. The magmatic rocks of this region are represented by alkaline granitoids. Some deposits of REE and rare metals are linked with these rocks.

目的：通过多中心临床研究分析高强度聚焦超声治疗不能手术胰腺癌的1年生存情况。方法：2013年1月到2014年1月,中国和保加利亚的不能手术的胰腺癌患者32例,男/女=20/12,年龄41~81（59.8±9.1）岁。胰腺癌病灶最大径20~60（39.3±9.6）mm,远处转移/无转移的患者18/14例。接受HIFU和/或化疗。记录术后并发症,疼痛变化和生存情况。使用Kaplan-Meier法计算总生存率和中位生存时间,比较化疗与否、是否发生远处转移的患者生存率有无差异（Log-Rank检验）。结果：术后1月,皮肤浅Ⅱ°烧伤者2例,经保守处理后1~2周愈合。伴有胰腺癌相关性疼痛症状的患者30例与术前比较,减轻的24例（80.0%）,不变的5例（16.7%）,加重的1例（3.3%）。所有患者的1年生存率为38.4%,中位生存时间为12个月。接受辅助化疗的患者1年生存率为57.4%,中位生存时间12月;未接受辅助化疗的患者1年生存率为20.8%,中位生存时间为6月;二者间比较有显著性差异。伴有远处转移的患者1年生存率为0%,中位生存时间为7月;无远处转移的患者1年生存率为49.2%,中位生存时间为12月;二者间比较无统计学差异。结论：中国和保加利亚的不能手术胰腺癌患者均能安全完成HIFU治疗,1年生存率和中位生存时间优于其它非手术治疗手段。辅助化疗能增加生存受益,远处转移是预后不良因素。
