The outcrops of Amdo gneiss is about 30 km south of Amdo County in north- ern Tibet. The field occurrence, mineral composition, textural characteristics, and whole-rock geochemical features of the four gneiss samples indicate the protolith of the gneisses is intermediate-acid intrusive rock. Gneiss zircon trace element tracing and genetic analysis shows that zircon has typical characteristics of magmatic zircon. The 2~6pbF38U concordant age of zircon is 505-517 Ma, corresponding to the Middle-Late Cambrian, which is the formation age of the protolith. The samples have char- acteristics of high silicon, alkali-rich, alkalic rate AR =1.73-3.7, the differentiation index DI = 70.78-90.28; rock aluminum saturation index ranges from 1.02 to 1.05, FeO / MgO ranges from 2.63 to 4.50, 10000 x Ga/AI ranges from 2.12 to 2.41, and P205 and A1203 content decreased with SiO2 increasing. Th and Y contents have a good positive correlation with Rb content; the genetic type of protolith of the gneiss is the differentiation of subalkaline over aluminum I-type granite. Combined with re- gional data, the tectonic setting of the Amdo gneiss protolith is closely related to the collision orogenic process. The prelimi- nary view is that the Middle-Late Cambrian magmatic events developed on the microcontinent could be the result of Andean- type orogeny along the Gondwana super-continental margin after the end of the Pan-African orogeny.展开更多

Methods Eighty patients were randomly divided into an electroacupuncture combined with heat-sensitive moxibustion group（group A, n=40） and a western medicine group（group B, n=40）. Zǐgōng（子宫 EX-CA 1）, Xuèhǎi（血海 SP 10）, Gānshū（肝俞 BL 18） and Shènshū（肾俞 BL 23） were selected in group A, and acupuncture combined with heat-sensitive moxibustion were carried out. Climen was taken orally in group B. The score changes of menstrual cycle, tidal fever and sweatiness, emotional excitement, soreness and weakness of waist and knees, dizziness and tinnitus, as well as the cured and markedly effective rate of the patients in the two groups before and after two courses of treatment were compared. Results The cured and markedly effective rate of group A was 72.5%（29/40）, which was superior to that of group B（37.5%, 15/40）（ P〈0.05）. The symptom scores were improved significantly in the two groups after treatment（all P〈0.05）, and the improvement in group A was superior to that in group B（all P〈0.05）. Conclusion The efficacy of electroacupuncture combined with heat-sensitive moxibustion is superior to that of conventional western medicine in treatment of premature ovarian failure.展开更多
