Objective： To demonstrate the validity and reliability of volumetric quantitative computed tomography （vQCT） with multi-slice computed tomography （MSCT） and dual energy X-ray absorptiometry （DXA） for hip bone mineral density （BMD） measurements, and to compare the differences between the two techniques in discriminating postmenopausal women with osteoporosis-related vertebral fractures from those without. Methods： Ninety subjects were enrolled and divided into three groups based on the BMD values of the lumbar spine and/or the femoral neck by DXA. Groups 1 and 2 consisted of postmenopausal women with BMD changes 〈-2SD, with and without radiographically confirmed vertebral fracture （n= 11 and 33, respectively）. Group 3 comprised normal controls with BMD changes 〉-ISD （n-46）. Post-MSCT （GE, LightSpeed16） scan reconstructed images of the abdominal-pelvic region, 1.25 mm thick per slice, were processed by OsteoCAD software to calculate the following parameters： volumetric BMD values of trabecular bone （TRAB）, cortical bone （CORT）, and integral bone （INTGL） of the left femoral neck, femoral neck axis length （NAL）, and minimum cross-section area （mCSA）. DXA BMD measurements of the lumbar spine （AP-SPINE） and the left femoral neck （NECK） also were performed for each subject. Results： The values of all seven parameters were significantly lower in subjects of Groups 1 and 2 than in normal postmenopausal women （P〈0.05, respectively）. Comparing Groups 1 and 2, 3D-TRAB and 3D-INTGL were significantly lower in postmenopausal women with vertebral fracture（s） [（109.8±9.61） and （243.3±33.0） mg/cm^3, respectively] than in those without [（148.9±7.47） and （285.4±17.8） mg/cm^3, respectively] （P〈0.05, respectively）, but no significant differences were evident in AP-SPINE or NECK BMD. Conclusion： the femoral neck-derived volumetric BMD parameters using vQCT appeared better than the DXA-derived ones in discriminating osteoporotic postmenopausal women with vertebral fractures from those wit

Effects of ketamine on proinflammatory cytokines and nuclear factor kappaB in polymicrobial sepsis rats

引用

World Journal of Gastroenterology 2006年第45期12卷 7350-7354页

作者： Xue-Min Song jian-Guo Li Yan-Lin Wang Qing Zhou Zhao-hui Du Bao-hui jia jian-Juan Ke Department of Anesthesiology Zhongnan Hospital of Wuhan University Wuhan 430071 Hubei Province China

AIM： To explore the effects of ketamine on hemodynamics, plasma proinflammatory cytokine （TNF-α and IL-6） levels and nuclear factor kappa B （NF-κB） activation during polymicrobial sepsis. METHODS： Male Sprague-Dawlay rats were subjected to cecal ligation and puncture （CLP） or sham operation. The rats were randomly assigned into four equal groups： sham CLP group, CLP group, ketamine （KT）Ⅰ group and KTⅡgroup. Thirty minutes before CLP, ketamine （5 mg/kg per hour and 10 mglkg per hour, respectively） was infused continuously through the left femoral vein cannula in KT Ⅰ group or KTⅡgroup. Sham CLP group and CLP group received 0.9% saline only （5 mL/kg per hour）. The right femoral artery was cannulated to monitor mean arterial pressure （MAP） and heart rates （HR）,and draw blood samples. The proinflammatory cytokine （TNF-α and IL-6） levels of plasma were measured using enzyme-linked immunosorbent assays （ELISA）. The hepatic NF-κB activation was determined by Western blot and HPIAS 2000 image analysis system. Twenty hours after CLP, the rats were killed by right femoral artery phlebotomization. RESULTS： CLP produced progressive hypotension, and a first increase followed by a decrease in HR. The hypotension was prevented, and the HR was slightly steady in ketamine treated rats. TNF-α levels of plasma reached a peak value at 2 h after CLP. Ketamine （KT Ⅰ group or KTⅡgroup） caused a significant decrease compared with CLP group at 2, 5 and 9 h time points after CLP （14.3 ± 1.9 vs 4.3 ± 0.9, 9.7 ± 1.4 vs 4.3 ± 0.9; 9.3 ± 1.5 vs 4.3 ± 0.9, 8.7 ± 1.4 vs 4.3 ±0.9; 6.0 ± 1.5 vs 5.0 ± 1.7, 5.3 ± 0.8 vs 5.0 ± 1.7; P 〈 0.01, respectively）. The IL-6 levels of plasma firstly ascended and then descended in CLP group, and reached a peak value at 9 h after CLP. Ketamine （KT I group or KTH group） caused a significant decrease compared with CLP group at 5, 9 or 20 h after CLP （135.0 ± 52.6 vs 60.0 ± 16.3, 112.5 ± 52.6 vs 60.0 ± 16.3; 410.0 ± 68.7 vs 62.5 ± 12.5, 250.0 ± 28.0 vs 62.5 ± 12.

Understanding the local structure and thermophysical behavior of Mg-La liquid alloys via machine learning potential

引用

International Journal of Minerals,Metallurgy and Materials 2025年第2期32卷 439-449页

作者： jia Zhao Taixi Feng Guimin Lu National Engineering Research Center for Integrated Utilization of Salt Lake Resource East China University of Science and TechnologyShanghai 200237China Joint International Laboratory for Potassium and Lithium Strategic Resources East China University of Science and TechnologyShanghai 200237China

The local structure and thermophysical behavior of Mg-La liquid alloys were in-depth understood using deep potential molecular dynamic(DPMD) simulation driven via machine learning to promote the development of Mg-La alloys. The robustness of the trained deep potential(DP) model was thoroughly evaluated through several aspects, including root-mean-square errors(RMSEs), energy and force data, and structural information comparison results;the results indicate the carefully trained DP model is reliable. The component and temperature dependence of the local structure in the Mg-La liquid alloy was analyzed. The effect of Mg content in the system on the first coordination shell of the atomic pairs is the same as that of temperature. The pre-peak demonstrated in the structure factor indicates the presence of a medium-range ordered structure in the Mg-La liquid alloy, which is particularly pronounced in the 80at% Mg system and disappears at elevated temperatures. The density, self-diffusion coefficient, and shear viscosity for the Mg-La liquid alloy were predicted via DPMD simulation, the evolution patterns with Mg content and temperature were subsequently discussed, and a database was established accordingly. Finally, the mixing enthalpy and elemental activity of the Mg-La liquid alloy at 1200 K were reliably evaluated,which provides new guidance for related studies.

2005-2007年对紫贻贝(Mytilus galloprovincialis)和厚壳贻贝(Mytilus coruscus)种间进行了杂交生产性试验,通过亲贝强化培育、确认雌雄亲贝、改革育苗水体交换方法、投喂混合单细胞藻类、流水培养附着稚贝等技术,获得F1代。结果表明,正交F1代幼虫的成活率明显高于反交F1代和厚壳贻贝,在幼虫培育前期与紫贻贝的成活率相当,但随着幼虫的发育有高于紫贻贝的趋势。正交F1代幼虫的壳长和壳高在培育阶段的前期生长与紫贻贝相当,低于厚壳贻贝,高于反交F1代;但后期的生长明显增快,并高于反交F1代和其他两种贻贝。各试验组贻贝海区养殖的成活率在90%以上,正交F1代最高,显著高于反交F1代。各试验组生长特性,正交F1代>紫贻贝>厚壳贻贝>反交F1代。其中正交F1代获附着稚贝3.77×109ind。正交F1除在孵化率上低于紫贻贝、厚壳贻贝外,在壳长、壳高、成活率等方面指标具有一定杂交优势,而反交F1代的杂交优势不明显。

THE DISTRIBUTION-FREE NEWSVENDOR PROBLEM WITH BALKING AND PENALTIES FOR BALKING AND STOCKOUT

引用

Journal of Systems Science and Systems Engineering 2014年第2期23卷 153-175页

作者： hui Yu jia Zhai School of Economics and Business Administration Chongqing University School of Business Administration Chongqing University of Technology

This paper investigates the ordering policy for the newsvendor problem with customer balking and penalties for balking and stockout. Our analysis is based on the assumption that only the mean and the variance of the demand distribution are known. In contrast to the existing research, we provide a new tradeoff tool as a replacement of the traditional one to weigh the holding cost and the goodwill cost segment： the balking penalty cost and the stockout penalty cost. Specifically, in addition to the stockout penalty, we also introduce the balking penalty, provide a new proof of the optimality of robust ordering policy to guarantee that the lower bound of expected profit obtained by us is tight, and get an robust optimal order quantity which is an exact solution but not an approximate one as before. Numerical experiments are conducted to illustrate the effect of penalties for balking and stockout.
