Rubidium(Rb)deposits mostly occur in the South China and Central Asia orogenic belts and are often closely associated with highly differentiated granites.This study investigates a newly-discovered giant Rb deposit at Gariatong in the Central Lhasa terrane in Tibet.Detailed field studies and logging data revealed that the Rb mineralization mainly occurs in monzogranite and is related to greisenization.LA-ICP-MS U-Pb dating of zircon yielded ages of 19.1±0.2 Ma and 19.0±0.2 Ma for greisenized monzogranite and fresh monzogranite,respectively.The monzogranites are characterized as strongly peraluminous,with high contents of SiO2,Al2O3,K2O and Na2O as well as a high differentiation index.They are enriched in light rare earth and large ion lithophile elements with significant negative Eu anomalies and depleted high fieldstrength elements.Petrological and geochemical features of these ore-related monzogranites suggest that they are highly fractionated S-type granites,derived from remelting of crustal materials in a post-collisional setting.The geochemistry of zircon and apatite points to a low oxygen fugacity of the ore-related monzogranite during the magma’s evolution.The discovery of the Gariatong Rb deposit suggests that the Central Lhasa terrane may be an important region for rare metal mineralization.

Increasing evidence supports the hypothesis of autologous immune attack in severe aplastic anemia(SAA):the predominant role of activated cytotoxic T cells(CTL)expressing-interferon in inhibiting the growth of bone marrow(BM)cells,putative autoantigens,and oligoclonal expansion of CD8+T cells.1 For SAA patients,the definitive therapies are immunosuppressive therapy(IST)or hematopoietic stem transplantation(HSCT).

为了研究驻涡加力燃烧室凹腔稳定器的冷却特性,设计了三种不同冷却结构的凹腔稳定器。采用实验研究的方法,对不同冷却结构的凹腔稳定器冷却特性进行研究,同时改变试验中凹腔油气当量比、次流与主流流量比(0.25~0.37)和主流马赫数(0.17~0.26),分析不同结构和气流参数下了凹腔冷却特性。结果表明:驻涡加力燃烧室的凹腔稳定器壁面最高温度出现在前壁面,前壁面温度较上壁和后壁偏高300K左右;凹腔稳定器壁温受冷却孔开孔率、凹腔油气比、次流与主流流量比影响较大,受马赫数影响较小。综合考虑各个方案试验结果,在凹腔稳定器冷却孔开孔率较低时,凹腔内部油气当量比建议取1.2~1.5。

Conducting scientific drilling on subglacial lakes and obtaining samples of subglacial lake water holds great significance in unraveling the formation and evolution of Antarctic subglacial lakes and early Earth's life forms. Despite various approaches to access and directly sample subglacial water and sediments, clean access and exploration of subglacial lakes remain challenging.To address this concern, Jilin University has developed the RECoverable Autonomous Sonde(RECAS) prototype. This technology enables sampling and in-situ detection of subglacial lake water while being isolated from the surface, thus minimizing the risk of pollution. Laboratory tests, including downward and upward drilling, long-running, remote-control, and cold-environment assessments, were conducted to validate the sonde's principle and functionality. During the 38th Chinese National Antarctic Research Expedition, CHINARE(2021–2022 season), the RECAS prototype underwent testing on the flank region of D?lk glacier, 10 km from Zhongshan Station in Antarctica. Three boreholes with depths of 200.3, 183.2, and 133.5 m were successfully drilled, with the refrozen meltwater sealing the boreholes during the process. Approximately 600 mL of melted water samples were collected from each hole. Throughout the drilling tests, all systems of the RECAS prototype performed within the expected ranges.

为研究弹性支撑刚度对矩形钢管混凝土翼缘工字形梁稳定性能的影响,开展了集中荷载作用下3根带有不同弹性支撑刚度的矩形钢管混凝土翼缘工字形梁的稳定性能试验,研究试验梁的位移及应变的变化规律,获得梁的失稳形式和稳定承载力。试验结果表明,整个加载破坏过程分为三个阶段,即弹性阶段、弹塑性阶段和破坏阶段,3根试验梁均发生整体弯扭屈曲失稳。随着弹性支撑刚度增加,梁稳定承载力增大,验证了设置弹性支撑可有效地提高该梁的稳定承载力。在试验基础上,利用ANSYS有限元软件对该梁进行非线性屈曲分析,将获得的稳定承载力与试验结果进行对比,误差均小于5%,从而验证有限元分析方法的正确性。最后,研究了混凝土强度、上翼缘含钢率和腹板高厚比等参数对该类梁稳定性能的影响规律。研究表明,增大上翼缘钢管含钢率和减小腹板高厚比均可明显提高该类梁的稳定承载力,而增强混凝土强度对梁的稳定承载力提高较小。

Effects of exercise therapy on bone mineral density in earlypostmenopausal women: a controlled trial

引用

Frontiers of Medicine 2009年第3期3卷 323-329页

作者： shilin deng Department of Physical Education Wuhan University of TechnologyWuhan 430070China

The purpose of this article is to determine the effect of a well-designed combined aerobic,resistance,and extension exercise program on bone mineral density(BMD)in postmenopausal women.The population comprised 45 postmenopausal women,who exercised over 12 months(exercise group),and 36 women who served as a non-training control group.BMD of the hip,and lumbar spine was measured at the baseline and 12th month.Repeated measurement analysis of variance and nonparametric test were utilized to compare differences between the exercise group and controls.Thirty-six out of 45 persons in the exercise group and 36 controls completed the study.Average compliance was 82.2%for the whole exercise group at the 12th month.All the subjects had decreased BMD,but the rate of bone loss was lower in the exercise group than in the control group at the L4 and hip.Although the exercise program in this study may probably reduce the rate of bone loss in weight-bearing skeletal sites,we do not suggest the exercise by itself be viewed as prevention or treatment for osteoporosis.Further,the exact dose-response relationship of exercise and bone mass in early postmenopause is not clear.

Can statins reduce risk of lung cancer,especially among elderly people? A meta-analysis

引用

Chinese Journal of Cancer Research 2013年第6期25卷 679-688页

作者： Zhantao deng Shu Zhang Long Yi shilin Chen Department of Thoracic Surgery Jiangsu Cancer Hospital Affliated to Nanjing Medicinal University Key Laboratory of Medical Molecular Technology Medical School of Nanjing University Nanjing Drum Tower Hospital

Objective： As the most common cause of cancer mortality throughout the world, lung cancer has drawn people＇s attention on how to reduce the risk with chemopreventive ways. Many epidemiological studies have shown inconsistent effects of statins on lung cancer, but some observational studies have showed that statins had protective effect on lung cancer among elderly people. So we preformed this meta-analysis to find whether statins were chemopreventive. Methods： We searched MEDLINE, EMBASE and Web of Science databases from inception to September, 2013. A total of 23 studies were selected, including 15 observational studies and 8 randomized controlled trials （RCTs）. Both fixed and random-effects models were used to calculate pooled estimates in primary and sensitivity analyses. We used Q and 12 statistics to assess statistical heterogeneity, and evaluated publication bias by Begg＇s test and Egger＇s test. Results： No association between statins and lung cancer risk was identified either in the meta-analysis among RCTs [relative risk （RR）： 0.95, 95% confidence interval （95% CI）： 0.85-1.06] or observational studies （RR： 0.89, 95% CI： 0.77-1.04）. We also selected 6 observational studies that all researched on elderly people. The result of meta-analysis showed that there was still no protective effect between statins and lung cancer among elderly people （RR： 1.03, 95% CI： 0.96-1.11）. Conclusions： Our results did not support a protective effect of statins on the overall lung cancer risk and the lung cancer risk among elderly people. More well-designed RCTs are needed to enhance our understanding of the chemopreventive effect of statins on lung cancer.
