川南"都掌蛮"岩画研究

四川珙县麻塘坝的岩画及悬棺葬 ,是汉魏唐宋僚人 (僰人 )、元明时期都掌人在同地域同时代的遗存。川南都掌蛮继承了古代僚人的主要习俗 ,岩画在头饰椎髻、使用铜鼓、巫术活动、猎头祭祀等方面 ,呈现出与悬棺葬俗相同的文化特质 ,揭示了岩画与悬棺葬之间的密切关系。岩画以丰富的文化内涵 ,折射出都掌蛮及其先民在生存发展、经济生活、文化传统、宗教习俗诸方面的活动痕迹 ,岩画是都掌蛮刻画在峭壁上的史诗     

对矿产资源可持续开发利用的思考

中国要实现全面建设小康社会和现代化建设的目标,不能走过度消耗自然资源特别是不可再生矿产资源的老路.必须立足于中国国情,落实科学发展观,切实转变经济增长方式,走新型工业化道路,矿产资源的可持续发展战略应当确立适度利用的对策,以促进和保证经济社会的可持续发展.     

中国岩画中的原始宗教文化考释

岩画作为流传至今的人类最早最辉煌的艺术遗产,也是远古人类活动的真实记录.在我国岩画中,有很多有关原始宗教的题材,主要表现了自然崇拜、图腾崇拜、祖先崇拜、生殖崇拜等方面的内容.中国岩画中所反映的原始宗教已大致具备某些人为宗教的特质和要素,既高于一般意义的原始宗教又不能纳入到人为宗教的范畴,是介于原始宗教和人为宗教之间的一种过渡形态,属于变异原始宗教类型,在一定程度上具有地域民族宗教的特色和意义.     

Effects of testosterone replacement therapy on hypogonadal men with osteopenia or osteoporosis: a subanalysis of a prospective randomized controlled study in Japan (EARTH study)

Objective: We investigated the effects of testosterone replacement therapy (TRT) on bone mineral density (BMD) among hypogonadal men with osteopenia/osteoporosis.

Methods: From our previous EARTH study population, 74 patients with a clinical diagnosis of osteopenia or osteoporosis and hypogonadism were included in this study, as the TRT (n?=?35) and control (n?=?34) groups. The TRT group was administered 250?mg of testosterone enanthate injection every 4 weeks for 12 months. The BMD, waist circumference, body mass index, body fat percentage, and muscle volume were measured at baseline and at 12 months. Blood biochemical data, including total cholesterol, triglycerides, HDL-cholesterol, hemoglobin A1c, and adiponectin values were also evaluated.

Results: At the 12-month visit, BMD significantly increased in both groups. However, comparisons on changes of parameter values from baseline to the 12-month visit between the TRT and control groups were significantly different in BMD (5.0?±?5.0 vs. 3.0?±?3.2; p?=?.0434) and in adiponectin value (?0.90?±?3.33 vs. 0.10?±?2.04; p?=?.0192). There were no significant changes in other parameters.

Conclusions: TRT for 12 months could improve BMD with a decrease in adiponectin levels among hypogonadal men with osteopenia/osteoporosis.     

An association between bone mineral density and anabolic hormones in middle-aged and elderly men with prediabetes

Introduction: Prediabetes (PD) leads to reduced testosterone (T) in males, but the association between the anabolic hormones and bone mineral density (BMD) remains unknown.

Objectives: We investigated an association between the anabolic hormones and BMD in middle-aged and elderly men with PD.

Methods: We investigated 84 prediabetic and 56 control men. Total T (TT), calculated free T (cFT), and dehydroepiandrosterone sulfate (DHEAS) were measured, and BMD was assessed using DXA methods.

Results: Patients with PD had lower TT (p?p?<?.005), and DHEAS (p?<?.02) than control group. BMD values of the lower lumbar spine (p?<?.02) and total body (p?<?.05) in prediabetic men were lower than in control group. Lumbar spine BMD correlated with TT (r?=?0.376), cFT (r?=?0.235), and HbA1c (r?=??0.368); femoral neck BMD correlated with TT (r?=?0.412) and cFT (r?=?0.421). The high lumbar spine and femur neck BMD was associated with high TT, cFT, and low HbA1c, while the high total body BMD with high TT, cFT, and low HbA1c.

Conclusion: The anabolic hormones significantly affect BMD in male with PD, and screening for low BMD is necessary in these patients.     

抗日歌曲中的记忆

发生于1937年至1945年间的抗日战争对所有中国人来说是一场无法忘记的民族战争。在抵抗侵略过程中,中国人民所表现出来的伟大的民族主义精神是人类历史上的宝贵财富,为后代树立了楷模。在战争期间作为一种对抗日活动的支持,民族音乐家创作了大批的抗日歌曲,以音乐的形式反映人们反帝反封建的革命意识,表现出鲜明的政治倾向和军事化特点。这些歌曲不仅以艺术的形式记录了伟大的革命事业,帮助人们记住革命的历史与传统,而且为日后的音乐创作和音乐生活提供了深刻的经验。     

辽代矿产资源的开发与利用

契丹民族在很早的时代就已经学会了开发和利用矿产资源,并掌握了金属开采、冶炼和制造等技术。契丹民族开采的矿种有银、铜、铅和铁等,冶炼和制造技术发达,他们主要制造生产工具和生活用具。论述了辽代的矿产资源的开发和金属冶炼,及辽代矿产资源的利用。     

任楼煤矿地应力测量与分析

本文介绍了空心包体应力解除法的基本原理和方法,并利用其对任楼煤矿地应力进行了测量。实测结果表明,任楼煤矿地应力以水平应力为主导,且水平应力大于铅直应力,并随深度的增加而增大。每个测点的应力状态与其所处的构造部位、岩体结构、岩性分布等有关。这些分布特征对矿井深部的巷道支护及矿井灾害的防治有着重要的指导意义。
