Technique of Distal Tendon Excision for the Treatment of Chronic Pain Caused by Isolated Proximal Gracilis Tears.

Proximal gracilis tear is a rare sports-related injury that can easily lead to misdiagnosis and underdiagnosis. Clinical manifestations are dominated by localized pain, tenderness, and dysfunction. Here, we report a therapy of proximal segmental tear of the gracilis and demonstrate its treatment process and clinical outcome.

Multimodal separation and cross fusion network based on Raman spectroscopy and FTIR spectroscopy for diagnosis of thyroid malignant tumor metastasis.

The diagnosis of cervical lymph node metastasis from thyroid cancer is an essential stage in the progression of thyroid cancer. The metastasis of cervical lymph nodes directly affects the prognosis and survival rate of patients. Therefore, timely and early diagnosis is crucial for effective treatment and can significantly improve patients' survival rate and quality of life.

Diagnosis of systemic lupus erythematosus using cross-modal specific transfer fusion technology based on infrared spectra and metabolomics.

Background: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease. Currently, the medical diagnosis of SLE mainly relies on the clinical experience of physicians, and there is no universally accepted objective method for diagnosing SLE. Therefore, there is an urgent need to design an intelligent approach to accurately diagnose SLE to assist physicians in formulating appropriate treatment plans.

Possible intermediate quantum spin liquid phase in α-RuCl under high magnetic fields up to 100 T.

Pursuing the exotic quantum spin liquid (QSL) state in the Kitaev material α-RuCl has intrigued great research interest recently. A fascinating question is on the possible existence of a field-induced QSL phase in this compound. Here we perform high-field magnetization measurements of α-RuCl up to 102 T employing the non-destructive and destructive pulsed magnets.

Signatures of a magnetic superstructure phase induced by ultrahigh magnetic fields in a breathing pyrochlore antiferromagnet.

The mutual coupling of spin and lattice degrees of freedom is ubiquitous in magnetic materials and potentially creates exotic magnetic states in response to the external magnetic field. Particularly, geometrically frustrated magnets serve as a fertile playground for realizing magnetic superstructure phases. Here, we observe an unconventional two-step magnetostructural transition prior to a half-magnetization plateau in a breathing pyrochlore chromium spinel by means of state-of-the-art magnetization and magnetostriction measurements in ultrahigh magnetic fields available up to 600 T.

Neuropeptide Y upregulates Runx2 and osterix and enhances osteogenesis in mouse MC3T3‑E1 cells via an autocrine mechanism.

The neuropeptide Y (NPY) system is considered one of the primary neural signaling pathways. NPY, produced by osteoblasts and other peripheral tissues, is known to inhibit biological functions of osteoblasts. However, until recently, little was known of the autocrine mechanism by which NPY is regulated.

Surface modification and chemical functionalization of carbon dots: a review.

Surface functional groups strongly affect the properties of carbon dots (CDs). Amino, carboxy, and hydroxy groups are most commonly encountered in CDs, and they can be introduced via covalent and noncovalent modification. This article (with 116 refs.

Formation of N, S-codoped fluorescent carbon dots from biomass and their application for the selective detection of mercury and iron ion.

Biomass is regarded as an excellent candidate for the preparation of heteroatom-doped carbon nanomaterials. We have developed a simple and facile one-pot synthesis of nitrogen and sulfur codoped fluorescent carbon dots from pigeon feathers, egg and manure via the pyrolysis carbonization method. The as-prepared four PCDs have high fluorescence quantum yield about 24.

N, B-doped carbon dots as a sensitive fluorescence probe for Hg(2+) ions and 2,4,6-trinitrophenol detection for bioimaging.

Nitrogen and boron co-doped carbon dots (BCNDs1-3) were prepared from three kinds of borate via a facile hydrothermal method. The as-prepared BCNDs did not shift with the change of excitation wavelength and possess good water dispersibility, strong fluorescence emission with high fluorescent quantum yield of 29.01%, 51.

Hydrogenated Oxygen-Deficient Blue Anatase as Anode for High-Performance Lithium Batteries.

Blue oxygen-deficient nanoparticles of anatase TiO2 (H-TiO2) are synthesized using a modified hydrogenation process. Scanning electron microscope and transmission electron microscope images clearly demonstrate the evident change of the TiO2 morphology, from 60 nm rectangular nanosheets to much smaller round or oval nanoparticles of ∼17 nm, after this hydrogenation treatment. Importantly, electron paramagnetic resonance and positronium annihilation lifetime spectroscopy confirm that plentiful oxygen vacancies accompanied by Ti(3+) are created in the hydrogenated samples with a controllable concentration by altering hydrogenation temperature.

The role of Sn in enhancing the visible-light photocatalytic activity of hollow hierarchical microspheres of the Bi/BiOBr heterojunction.

Hollow hierarchical microspheres of Bi/BiOBr (SBB) with oxygen vacancies were prepared using a one step solvothermal method. It was found that the stannous chloride dihydrate played key roles in the formation of Bi, defects and the stacking mode of hierarchical construction units. Positron annihilation lifetime spectroscopy (PALS) was used to demonstrate the oxygen vacancies in Bi/BiOBr samples.

[Study of therapeutic effect and mechanism of Sihuang powder treating acute synovitis in experimental rabbit induced by papain injection].

Objective: To prove the therapeutic effects of Sihuang powder (composed by four traditional Chinese herbs: root of baikal skullcap, bark of amur corktree, root of sorrel rhubarb, fruit of cape jasmine, which were mixed with wild Chrysanthemum flower solution)in treating acute synovitis in experimental rabbit knee osteoarthritic models induced by papain injection and to explore its mechanism.

Methods: Thirty-two New-Zealand white rabbits were divided into 6 groups: blank group, model group, Sihuang powder with high dosage group (2 g/kg), Sihuang powder with low dosage group (1 g/kg), Yingtaiqing group and wild Chrysanthemum flower group. The latter four groups were treated respectively with low and high dose Sihuang powder synovium and cartilage were tested concentrations of nitrogen monoxide (NO) and IL-1 level and then were prepared for pathologic and histologic observation 10 days later.
