[Systemic lupus erythematosus associated macrophage activation syndrome with neuropsychiatric symptoms: A report of 2 cases].

Systemic lupus erythematosus (SLE) associated macrophage activation syndrome (MAS) is clinically severe, with a high mortality rate and rare neuropsychiatric symptoms. In the course of diagnosis and treatment, it is necessary to actively determine whether the neuropsychiatric symptoms in patients are caused by neuropsychiatric systemic lupus erythematosus (NPSLE) or macrophage activation syndrome. This paper retrospectively analyzed the clinical data of 2 cases of SLE associated MAS with neuropsychiatric lesions, Case 1: A 30-year-old female had obvious alopecia in 2019, accompanied by emaciation, fatigue and dry mouth.

[Delimitation of urban development boundary based on ecological sensitivity evaluation and CA-Markov simulation in plain city:A case of Nanchang, Jiangxi, China].

The rational delimitation of urban development boundary plays an important role in guiding the orderly growth of urban space and ensure proper environment health of urban space. In this study, we evaluated the ecological sensitivity of Nanchang City from four aspects (soil erosion, habitat, geological disaster and water resource) and simulated urban expansion in 2020 based on CA-Markov and land use data in 2000, 2010 and 2015. Spatial decision-making analysis of the two aspects was carried out in combination to the future development of the study area.

Spatiotemporal patterns of the trade-off and synergy relationship among ecosystem services in Poyang Lake Region, China.

Poyang Lake region is the largest freshwater lake impacted area in China. Quantitative analysis of trade-off and synergy in ecosystem service is of great significance for realizing regional sustainable development. Based on multi-source data of remote sensing, soil, meteorology and DEM, we quantitatively measured food supply service, soil conservation service and water yield service in Poyang Lake region from 2005 to 2015, and analyzed their spatiotemporal patterns and evolution characteristics.

[Case-control study on calcaneal locking plates and tension band with Kirschner's nail for the treatment of patellar fracture].

Objective: To compare clinical effect between calcaneal locking plates and tension band with Kirschner's nail for the treatment of patellar fracture.

Methods: From December 2009 to December 2017, 58 patients with patellar fracture were divided into plate group(calcaneal locking plate) and tension band(tension band with Kirschner's nail) by surgical method. There were 29 patients in plate group, including 14 males and 15 females, aged from 18 to 72 years old with an average of (36.

Largely enhanced photocatalytic activity of Au/XS/Au (X = Re, Mo) antenna-reactor hybrids: charge and energy transfer.

An antenna-reactor hybrid coupling plasmonic antenna with catalytic nanoparticles is a new strategy to optimize photocatalytic activity. Herein, we have rationally proposed a Au/XS/Au (X = Re, Mo) antenna reactor, which has a large Au core as the antenna and small satellite Au nanoparticles as the reactor separated by an ultrathin two-dimensional transition-metal dichalcogenide XS shell (∼2.6 nm).

Strong magnetic resonances and largely enhanced second-harmonic generation of colloidal MoS and ReS@Au nanoantennas with assembled 2D nanosheets.

Colloidal disk-like and sphere-like MoS nanoantennas are synthesized. They consist of curly and interlaced 2D nanosheets. The resonance peak of the MoS nanoantennas can be tuned from 500 to 900 nm by adjusting the size and shape.

Plasmon-Enhanced Photoelectrochemical Current and Hydrogen Production of (MoS-TiO)/Au Hybrids.

Three component hybrid (MoS-TiO)/Au substrate is fabricated by loading plasmonic Au nanorods on the MoS nanosheets coated TiO nanorod arrays. It is used for photoelectrochemical (PEC) cell and photocatalyst for hydrogen generation. Owing to the charge transfer between the MoS-TiO hetero-structure, the PEC current density and hydrogen generation of TiO nanoarrays are enhanced 2.

[Minimally invasive percutaneous plate osteosynthesis for the treatment of intertrochanteric femoral fractures of Evans IlI and IV in elderly patients].

Reduced expression of PTEN and increased PTEN phosphorylation at residue Ser380 in gastric cancer tissues: a novel mechanism of PTEN inactivation.

Aim: PTEN is a tumor suppressor gene in different cancers. This study was to determine the protein expression of PTEN and phosphorylation of PTEN (p-PTEN) at residue Ser380 in different histology specimens of gastric tissues.

Objective: To explore the influence of Free-skin-grafted penoscrotal avulsion injuries on spermatogenesis.

Methods: Forty-two male New Zealand albino rabbits during child-bearing period were divided into the experimental group (n = 24) and the control group (n = 18) using random digits table, and 24 female rabbits with reproductive history were used for mating experiment. The experimental group animal's scrotum skin were excised, and the split skin from abdominal region was used to repair the skin defect of scrotum.

3D nanostructured Ni(OH)2 microspheres as an efficient immobilization matrix of Ru(bpy)3(2+) for high-performance electrochemiluminescence sensor.

The electrochemistry and electrochemiluminescence (ECL) of novel three-dimensional nanostructured Ru(bpy)(3)(2+)/Ni(OH)(2) microspheres were investigated for the first time. The negatively charged porous Ni(OH)(2) microspheres composed of Ni(OH)(2) nanowires were specifically designed to interact with Ru(bpy)(3)(2+). The large surface area and porous structure of Ni(OH)(2) microspheres enhance loading of Ru(bpy)(3)(2+) and mass transport of the model analyte, tripropylamine (TPA).
