[Successful treatment of rheumatoid arthritis complicated with myasthenia gravis with low-dose rituximab: A case report].

Rheumatoid arthritis (RA) and myasthenia gravis (MG) are two distinct autoimmune diseases. Compared with the general population, the incidence of RA is notably higher among patients with MG. Similarly, the rate of MG in patients diagnosed with RA is also significantly increased.

[IgA vasculitis with necrosis of the small intestine secondary to monoclonal gammopathy of renal significance: A case report].

Monoclonal gammopathy of undetermined significance combined with renal damage is named monoclonal gammopathy of renal significance. There are few reports about IgA vasculitis in patients with monoclonal gammopathy of undetermined significance. Here, we report a case of monoclonal gammopathy of renal significance, who had manifestations of IgA vasculitis, including purpura, gastrointestinal bleeding and joint pain.

Epidemiological Investigation of Yak () Fascioliasis in the Pastoral Area of Qinghai-Tibet Plateau, China.

The objective of this investigation was to understand the epidemiology of fascioliasis in yaks in the alpine pastoral areas of the Qinghai-Tibet Plateau, China. The prevalence of infection was estimated by examining eggs in the feces of yaks and by autopsy after the slaughter. Yaks were sampled from a total of 16 representative counties in Qinghai province, and risk factors were assessed based on regional and age characteristics.

10 μm thick ultrathin glass sheet to realize a highly sensitive cantilever for precise cell stiffness measurement.

The micro-cantilever-based sensor platform has become a promising technique in the sensing area for physical, chemical and biological detection due to its portability, small size, label-free characteristics and good compatibility with "lab-on-a-chip" devices. However, traditional micro-cantilever methods are limited by their complicated fabrication, manipulation and detection, and low sensitivity. In this research, we proposed a 10 μm thick ultrathin, highly sensitive, and flexible glass cantilever integrated with a strain gauge sensor and presented its application for the measurement of single-cell mechanical properties.

A review on intelligent impedance cytometry systems: Development, applications and advances.

Impedance cytometry is a well-established technique for counting and analyzing single cells, with several advantages, such as convenience, high throughput, and no labeling required. A typical experiment consists of the following steps: single-cell measurement, signal processing, data calibration, and particle subtype identification. At the beginning of this article, we compared commercial and self-developed options extensively and provided references for developing reliable detection systems, which are necessary for cell measurement.

Anhydrobiotic chironomid larval motion-based multi-sensing microdevice for the exploration of survivable locations.

African chironomid () larvae can suspend their metabolism by undergoing severe desiccation and then resume this activity by simple rehydration. We present a microdevice using interdigital comb electrodes to detect the larval motion using the natural surface charge of the living larvae in water. The larvae were most active 2 h after soaking them in water at 30°C; they exhibited motions with 2 Hz frequency.

Transcriptome analysis reveals the regulatory mechanism by which suppresses adventitious shoot formation in apple.

Adventitious shoot (AS) regeneration accelerates plant reproduction and genetic transformation. is involved in many biological processes, but its regulation of AS regeneration has not been reported. Here, we showed that the genotype and CK/IAA ratio of apple leaves were the key factors that affected their capacity for AS formation.

Prevalence and genetic diversity of Echinorhynchus gymnocyprii (Acanthocephala: Echinorhynchidae) in schizothoracine fishes (Cyprinidae: Schizothoracinae) in Qinghai-Tibetan Plateau, China.

Background: The schizothoracine fishes, an excellent model for several studies, is a dominant fish group of the Qinghai-Tibet Plateau (QTP). However, species populations have rapidly declined due to various factors, and infection with Echinorhynchus gymnocyprii is cited as a possible factor. In the present study, the molecular characteristics of E.

Effects of alendronate and alfacalcidol on bone in patients with myasthenia gravis initiating glucocorticoids treatment.

Objective: Glucocorticoids (GCs) are the first-line treatment for myasthenia gravis (MG) and act as long-term immunosuppressants. However, GCs can induce osteoporosis and bone fractures. In this study, we evaluate the effects of oral alendronate and alfacalcidol, or alfacalcidol alone on the bone of Chinese patients with MG who will initiate treatment with GCs.

Association Between Geranylgeranyl Pyrophosphate Synthase Gene Polymorphisms and Bone Phenotypes and Response to Alendronate Treatment in Chinese Osteoporotic Women.

Objective To investigate the relationship between geranylgeranyl pyrophosphate synthase (GGPPS) gene polymorphisms and bone response to alendronate in Chinese osteoporotic women.Methods A total of 639 postmenopausal women with osteoporosis or osteopenia were included and randomly received treatment of low dose (70 mg per two weeks) or standard dose (70 mg weekly) of alendronate for one year. The six tag single nucleotide polymorphisms of GGPPS gene were identified.

Novel mutations in FKBP10 in Chinese patients with osteogenesis imperfecta and their treatment with zoledronic acid.

Osteogenesis imperfecta (OI) is a group of hereditary disorders characterized by decreased bone mass and increased fracture risk. The majority of OI cases have an autosomal dominant pattern of inheritance and are usually caused by mutations in genes encoding type I collagen. OI cases of autosomal recessive inheritance are rare, and OI type XI is attributable to mutation of the FKBP10 gene.

Osteogenesis imperfecta type V: Genetic and clinical findings in eleven Chinese patients.

Introduction: Osteogenesis imperfecta (OI) type V is a rare inherited disease characterized by multiple fractures, intraosseous membrane calcification, and hypercallus formation. We investigate the causative gene, phenotype and also observe the effects of zoledronic acid in Chinese OI type V patients.

Methods: The clinical phenotype and causative gene mutation was investigated in eleven patients with type V OI.

THE CLINICAL CHARACTERISTICS AND EFFICACY OF BISPHOSPHONATES IN AUDLT PATIENTS WITH OSTEOGENESIS IMPERGECTA.

Objective: Osteogenesis imperfecta (OI) is characterized by low bone mass and recurrent fractures. Adults with OI are often treated with oral or intravenous bisphosphonates (BPs). We investigated the clinical phenotypes of adult OI patients and prospectively compared the efficacy of oral alendronate (ALN) with intravenous zoledronic acid (ZOL) in OI patients.
