The structure properties for even–even nuclei around^(230)U,located on the hexadecapoledeformation island,are investigated using the potential-energy-surface calculation within the framework of the macroscopic-microscopic model.The impact of different deformation degrees of freedom(including axial and nonaxial quadrupole and hexadecapole deformations)on total energy,shell,and pairing contributions is analyzed,based on the projected energy maps and curves.The single-particle structure is presented and briefly discussed.To a large extent,a much better agreement with experimental data and other theoretical results is obtained if the hexadecapole deformations,especially the axial one,are taken into account.These results could provide useful insights into understanding the effects of different quadrupole and hexadecapole deformations.

Aneuploidy rates in embryos produced by assisted reproduc- tive technologies commonly exceed 50%, particularly in couples where the woman is of advanced maternal age or has experienced repeated implantation failure （Harper et al., 2012）. Pre-implantation genetic diagnosis （PGD） conducted at many fertility clinics worldwide is now a frontline treatment for infertile couples with a poor prognosis for pregnancy as well as couples where one partner is a carrier of a balanced translocation （Munne, 2012）.

配电网灵活性提升优化过程中易受不均匀电压、强磁场、电流效应等问题的干扰,灵活性提升效果不明显。为了解决上述问题,提出适应多元源荷接入的配电网两阶段灵活性提升优化方法。该方法首先采用瞬时功率平衡算法保证配电网达到三相平衡状态,其次通过无功出力与有功损耗的输出特点实现配电网的无功规划,有效地提高配电网运行质量,降低网损。最后采用多元源荷接入的两阶段提升优化法提升配电网的灵活性,第一阶段基于灵活性三指标与多源源荷供给特性构建灵活性提升优化模型,第二阶段考虑配电网灵活性指标的概率平衡性,并采用线性转换算法对模型求解,完成配电网灵活性提升优化。试验结果表明,所提方法的网损率小,净负荷波动曲线小,计算时间短,配电网分布式电源接入的灵活适应性强。可见通过灵活性优化调度,可以有效提升含分布式电源配电网的灵活性,提高配电网接纳分布式电源的能力。

阴阳学说是在整体辨证指导下中医学朴素的辨证思想,阴阳盈亏的动态变化可以反应人体的生命活动。笔者团队在前期的文献调研和临床实践中发现“阳虚阴结”是结直肠癌发生的关键病机,阳气不足,痰、湿、瘀等属阴的代谢产物失于气化而积聚形成“阴瘤”,停滞于肠道而形成结直肠癌。阳化气是正常细胞代谢产生能量的过程,阳虚而阴邪之物不化在体内结聚而成瘤。阴阳失衡所产生的盈亏之变可引起体内的能量或物质代谢变化,其中谷氨酰胺是肿瘤细胞中消耗量最大的氨基酸,其代谢过程中不仅为肿瘤细胞生长提供物质基础,同时还可拮抗免疫细胞对谷氨酰胺的利用,并创造一种乏氧的酸性微环境,促进肿瘤细胞的增殖和生长。本文对结直肠癌细胞谷氨酰胺代谢的特点进行了详细的论述,旨在从“阳虚阴结”的病机阐述结直肠癌发生,并阐释中医药重塑肿瘤细胞代谢的科学理论,旨为结直肠癌的综合治疗提供新的思路和方法。

BACKGROUND Acupuncture is relatively popular worldwide,but an unregulated operation can easily lead to infections.The purpose of this report was to analyze a clinical case of surgery combined with the use of antibiotics for the treatment of thoracic vertebral infection by Escherichia coli(E.coli)after acupuncture.CASE SUMMARY A 63-year-old male was diagnosed with E.coli infection in the thoracic vertebra after acupuncture.His fever and pain did not improve after treatment with broadspectrum antibiotics for 10 d.Thus,debridement of the infected area and biopsy were decided.The final pathology confirmed the diagnosis of vertebral infection by E.coli.The patient underwent anterior and posterior thoracic vertebral debridement and internal fixation surgery combined with the use of sensitive antibiotics.He had no fever or backache 3 mo postoperatively.CONCLUSION In this report,we first considered antibiotic treatment for the patient with septic spinal infection,but the effect was not obvious.Interventional surgery was combined with the use of sensitive antibiotics to relieve backache,and good clinical results were achieved.Furthermore,acupuncture practitioners should pay attention to hygienic measures.

It is of great significance to synthesize carbon dots(CDs)with desirable hydrophilicity for the ever-growing application of CDs in different fields.In this study,the hydrophilic and hydrophobic CDs were facilely prepared by solvothermal treatment of o-dihydroxybenzene and urea in N,N-dimethylformamide(DMF).Optimization experiments revealed that the solvothermal temperature has a great impact on the surface states of the CDs.The hydrophobic CDs with a contact angle of 110.7°was obtained at 200℃.The structural and optical characterizations,along with theoretical calculations elucidated that the lipophilic nature of the CDs was resulting from the formation of polymer chains.The presence of extended conjugated sp^(2)-domains and amino groups contributed to the red emission of the CDs synthesized at low reaction temperatures(160-200℃).With the further increase of solvothermal temperature,the hydrophobic CDs were gradually transformed to the hydrophilic state accompanying the blue shift of the fluorescence of the CDs.The highly hydrophilic CDs with a contact angle of 25.9°were obtained at 240℃ due to the increased formation of hydrophilic functional groups on the surface of CDs.The red emissive CDs exhibited a sensitive color and fluorescence response to ethanol content while the fluorescence of the blue emissive CDs remained constant.By combining the two kinds of CDs,a dual-emission sensor was constructed,which was successfully applied for the evaluation of the alcoholic strength in commercial Baijiu commodities in both fluorometric and colorimetric modes.
