In vivo imaging of alkaline phosphatase in lipid metabolic diseases with a photoacoustic probe.

Lipid metabolic diseases have become an important challenge to global public health. Along with lifestyle changes, the incidence of obesity, diabetes and other metabolic syndromes is on the rise, and the number of patients with fatty liver disease is also increasing. Therefore, it is particularly important to develop effective lipid imaging strategies to monitor and manage fatty liver disease.

A case report of Erdheim-Chester disease-clinically characterized by recurrent fever, multiple bone destruction, and antinuclear antibodies.

Background: Erdheim-Chester disease is a form of histiocytosis. It is an extremely rare illness. Since its discovery, hundreds of cases of this disease have been identified across the globe.

Systemic lupus erythematosus complicated with reversible posterior encephalopathy syndrome: a case report.

A 28-year-old female patient was hospitalized primarily because of "intermittent fever for 28 days aggravated by systemic rashes, oral ulcer, and edema in both eyelids for 5 days." During treatment, convulsions and loss of consciousness occurred. Magnetic resonance imaging (MRI) of the head revealed an abnormal signal with shadows in the bilateral frontal, parietal, temporal, and occipital lobes; cerebellar hemispheres; and basal nodes, with high signal intensity on T2 weighted imaging (T2WI), on fluid-attenuated inversion-recovery, and of the apparent diffusion coefficient and low signal intensity on T1WI and diffusion weighted imaging.

Contralateral S1 nerve root transfer for motor function recovery in the lower extremity among patients with central nervous system injury: study protocol for a randomized controlled trial.

Background: Central nervous system injury (CNSI) comprises a series of common diseases that severely affect patients' motor function and quality of life and is associated with high disability and mortality rates. Previous studies have shown that contralateral lumbosacral nerve root transfer significantly improved the function of the paralyzed limb in rat models of CNSI. These studies showed that severing the sacral 1 nerve root (S1) did not damage the function of the ipsilateral lower extremity.

Differential gene and protein expression between rat tibial nerve and common peroneal nerve during Wallerian degeneration.

Wallerian degeneration and nerve regeneration after injury are complex processes involving many genes, proteins and cytokines. After different peripheral nerve injuries the regeneration rate can differ. Whether this is caused by differential expression of genes and proteins during Wallerian degeneration remains unclear.

Effect of exosomes from adipose-derived stem cells on the apoptosis of Schwann cells in peripheral nerve injury.

Aims: Recovery after peripheral nerve injury (PNI) is often difficult, and there is no optimal treatment. Schwann cells (SCs) are important for peripheral nerve regeneration, so SC-targeting treatments have gained importance. Adipose-derived stem cells (ADSCs) and their exosomes can promote peripheral nerve repair, but their interactions with SCs are unclear.

Effect of exogenous spastin combined with polyethylene glycol on sciatic nerve injury.

Polyethylene glycol can connect the distal and proximal ends of an injured nerve at the cellular level through axonal fusion to avoid Wallerian degeneration of the injured distal nerve and promote peripheral nerve regeneration. However, this method can only prevent Wallerian degeneration in 10% of axons because the cytoskeleton is not repaired in a timely fashion. Reconstruction of the cytoskeletal trunk and microtubule network has been suggested to be the key for improving the efficiency of axonal fusion.

High serum sICAM-1 is correlated with cerebral microbleeds and hemorrhagic transformation in ischemic stroke patients.

Intercellular adhesion molecule 1 (ICAM-1) is an adhesive protein involved in inflammatory responses and endothelial dysfunction. ICAM-1 expression is upregulated in cerebrovascular tissue affected by stroke. We investigated whether serum soluble ICAM-1 (sICAM-1) levels are associated with cerebral microbleeds (CMBs) and risk of hemorrhagic transformation (HT).

Uric acid demonstrates neuroprotective effect on Parkinson's disease mice through Nrf2-ARE signaling pathway.

Uric acid has neuroprotective effect on Parkinson's disease (PD) by inhibiting oxidative damage and neuronal cell death. Our previous study has shown that uric acid protected dopaminergic cell line damage through inhibiting accumulation of NF-E2-related factor 2 (Nrf2). This study aimed to investigate its in vivo neuroprotective effect.

Chemical Composition, Antioxidant, DNA Damage Protective, Cytotoxic and Antibacterial Activities of Cyperus rotundus Rhizomes Essential Oil against Foodborne Pathogens.

Cyperus rotundus L. (Cyperaceae) is a medicinal herb traditionally used to treat various clinical conditions at home. In this study, chemical composition of Cyperus rotundus rhizomes essential oil, and in vitro antioxidant, DNA damage protective and cytotoxic activities as well as antibacterial activity against foodborne pathogens were investigated.

Neuroprotective effects of bisperoxovanadium on cerebral ischemia by inflammation inhibition.

PTEN is a dual specificity phosphatase and is implicated in inflammation and apoptosis of cerebral ischemia and reperfusion (I/R) injury. Bisperoxovanadium (Bpv), a specific inhibitor of PTEN's phosphatase activity, has demonstrated powerful neuroprotective properties. We investigated the neuroprotective roles of Bpv in the rat model of middle cerebral artery occlusion (MCAO) cerebral I/R injury, and explored the modulation of inflammatory mediators and PI3K/Akt/GSK-3β pathways by Bpv.

Accurate segmental motor innervation of human lower-extremity skeletal muscles.

Background: There is limited knowledge about accurate segmental motor innervation of the human lower extremity skeletal muscles. The aim of the present study was to explore the truth of segmental motor innervation of the lower extremity.

Methods: Included in this study were 20 patients with unilateral fracture of the sacrum and sacral nerve injury, who underwent internal fixation and decompression of the sacral nerve in our hospital between June 2009 and January 2014.

[The re-evaluation of 140 patients diagnosed as ankylosing spondylitis and nonradiographic axial spondyloarthritis].

Objective: To re-evaluate the diagnoses of ankylosing spondylitis (AS) and nonradiographic axial spondyloarthritis (nr-axSpA) and analyze the incidence and reason of misdiagnosis.

Methods: Patients who were previously diagnosed as AS and nr-axSpA before referrals to Peking Union Medical College Hospital (PUMCH) were re-evaluated by three rheumatologists of PUMCH according to the modified New York criteria for AS and Assessment of SpondyloArthritis international Society (ASAS) axial SpA classification criteria for nr-axSpA.

Results: Totally 87 prior AS patients and 53 prior nr-axSpA patients were enrolled in this study.
