BACKGROUND The brown tumor is a kind of complication of hyperparathyroidism(HPT). The ultimate therapy usually is the resolution of HPT. We herein report an unlocatable HPT patient who received resection of a huge brown tumor of the rib, and experienced "self-recovery" of serum calcium and parathyroid *** SUMMARY A 34-year-old female patient who suffered from a gradually increasing mass of the left chest wall since 2007 came to our hospital for treatment. The patient had a history of serum Ca and parathyroid hormone(PTH) increasing since June 2015 and received zoledronic acid treatment for 17 mo. When she came to our hospital in November 2017 after discontinuing medical treatment for 3 mo, the serum Ca and PTH levels were within normal ranges. The patient had no imaging abnormalities of parathyroid ultrasound or 99 m Tc-methoxyisobutyl *** computed tomography revealed a local soft tissue mass of 96 mm × 113 mm with bone erosion of the left 8 th rib, and the mass presented irregular enhancement with an unclear boundary between the mass and spleen. The mass was thought to likely be caused by HPT, but a malignancy could not be ruled *** of the mass was performed, and the pathology proved that the mass was a brown tumor. A diagnosis of unlocatable HPT was considered. Since the serum Ca and PTH levels were both normal pre-and post-operation, the patient did not receive exploratory surgery for HPT, and received regular *** The huge brown tumor of the rib and "self-recovered" serum PTH and Ca levels are relatively rare in HPT patients. An exploratory operation may be deferred for these patients, and long-term follow-up should be performed.

A new Zn（Ⅱ） complex, [Zn（L）2（H2O）2], where H2L = N-（2-hydroxy-1-naphthyli- dene）-L-sedne, has been synthesized and characterized by single-crystal X-ray diffraction. The crystal belongs to monoclinic system, space group C2/c with a = 13.669（2）, b = 6.4657（9）, c = 31.463（5） A, β = 98.010（2）°, V = 2753.6（7） A^3, Z = 8, Mr = 358.64, Dc = 1.730 g/cm^3, F（000） = 1472,μ（MoKa） = 1.814 mm^-1, the final R = 0.0355 and wR = 0.0706. The Zn（Ⅱ） atom adopts a square-pyramidal geometry coordinated by the tridentate ligand and two water molecules. Intermolecular hydrogen bonds link the complex molecules into a two-dimensional layer.

A new and efficient way is presented for discrete integrable couplings with the help of two semi-direct sum Lie algebras. As its applications, two discrete integrable couplings associated with the lattice equation are worked out. The approach can be used to study other discrete integrable couplings of the discrete hierarchies of solition equations.

Graphene, as a fabulously new-emerging carbonaceous material with an ideal two-dimensional rigid honeycomb structure, has drawn extensive attention in the field of material science due to extraordinary properties, including mechanical robustness, large specific surface area, desirable flexibility, and high electronic conductivity. In particular,as an auxiliary material of electrode materials, it has the potential to improve the performance of lithium-ion batteries. However, wide utilization of graphene in lithium-ion batteries is not implemented since tremendous challenges and issues,such as quality,quantity, and cost concerns, hinder its *** remains a debate whether graphene can act as an impetus in the evolution of lithium-ion batteries. In this review, we summarize the desirable properties, several common synthesis methods as well as applications of graphene as the anode in lithium-ion batteries, seeking to provide insightful guidelines for further development of graphene-based lithium-ion batteries.

棉花蕾铃脱落是一个普遍存在的现象,有对逆境环境胁迫的主动适应性脱落,也有因品种遗传特性、环境条件、栽培措施以及生物和非生物胁迫被动的受损脱落。蕾铃脱落直接影响着棉花的产量,国内外现有公开报道多集中于20世纪50、60年代关于乙烯和脱落酸对棉花蕾铃脱落影响的初步发现。结合其他植物的研究结果来看,蕾铃脱落似乎与生长素、赤霉素和细胞分裂素等促生长类激素的下降以及乙烯和脱落酸等抑制生长类激素的升高密切相关,激素在植物体内不仅介导新陈代谢过程,还协调着与信号通路相关的调控因子,在脱落过程中起着关键作用。本文从植物激素调控入手,综述了近年来包括脱落区形成和作用的分子调控机制以及各激素在棉花蕾铃脱落以及其他植物(生殖)器官脱落过程中的响应和调控机制等。发现目前以棉花蕾铃脱落为对象的研究非常匮乏,且多集中于少数激素对棉花生殖生长影响的有限研究,缺乏对导致蕾铃脱落的深层次机制的探究和解析。因此,未来研究方向应着重于探究棉花蕾铃脱落的遗传基础、发掘新的抗脱落基因资源和培育抗脱落棉花品种,同时加强在以棉花为模型植物下,蕾铃脱落与植物激素调节的关系研究,为提高棉花产量提供理论依据和技术支持。

The variation of plant dead-time deeply a?ects the stability of the predictive PI controlsystem. It is important for designing and applying the PPI controller to calculate the delay margin.A criterion of stability for the PPI system and the quantitive relationship among the delay margin,the time constant of the closed-loop system, and the dead-time of the model are given. A graphicalgorithm to compute the delay margin is also developed. The phenomenon that there exist morethan one stability delay zones is discussed. The algorithm is shown to be precise by some simulations.
