The diagnosis and treatment of the epithelioid sarcomas involving the peripheral nerves.

Epithelioid sarcomas are rare soft tissue tumors and have possibility to involve the peripheral nerve and present as sensory and motor disorders. The symptoms are similar to those of nerve compression diseases. This situation is extremely rare in clinic and was only reported as several case reports in literature.

Decorin suppresses stemness and migration potential of malignant peripheral nerve sheath tumor through inhibiting epidermal growth factor receptor signaling.

Cancer stem cells (CSCs) play pivotal roles in the growth, invasion, metastasis, chemo-resistance in malignant peripheral nerve sheath tumor (MPNST). The current characterization of CSCs in MPNST is not complete. Decorin is a critical regulator of microenvironment, but its expression and function in CSCs of MPNST has not been studied.

A Modified Endoscopic Carpal Tunnel Release Surgery.

In this study, a modified version of the endoscopic carpal tunnel release surgery was introduced, which is safe and easy to handle. Moreover, the requirement for surgical instruments is low. Six patients with carpal tunnel syndrome underwent the modified procedure.

Study on the potential of sludge-derived humic acid as energy storage material.

As one of the main methods for sludge treatment, recovery of renewable biogas energy by anaerobic digestion (AD) is a promising strategy to deal with the conflict between carbon neutralization and sharply increase of sewage sludge. Humic acid (HA) in sludge is a major inhibitor of biogas yields and needs to be removed or pretreated. However, as the graphene oxide-like material, HA is an ideal precursor for the preparation of energy storage materials with high performance.

Brain CT registration using hybrid supervised convolutional neural network.

Background: Image registration is an essential step in the automated interpretation of the brain computed tomography (CT) images of patients with acute cerebrovascular disease (ACVD). However, performing brain CT registration accurately and rapidly remains greatly challenging due to the large intersubject anatomical variations, low resolution of soft tissues, and heavy computation costs. To this end, the HSCN-Net, a hybrid supervised convolutional neural network, was developed for precise and fast brain CT registration.

Intercostal nerve transfer for restoration of the diaphragm muscle function after phrenic nerve transfer in total brachial plexus avulsion.

Object: To determine the possibility of innervation of the diaphragm muscle using intercostal nerve after ipsilateral phrenic nerve transfer in total brachial plexus avulsion.

Methods: Bilateral phrenic nerves and the 9th intercostal nerves were observed inside the thorax. The point where the phrenic nerve entered the diaphragm muscle (point A), the point where the 9th intercostal nerve gave rise to the cutaneous branch (point B) and crossed the posterior axillary line (point C) and the point where the posterior axillary line met the insertion of the diaphragm muscle (point D) were identified.

Galvanic replacement mediated 3D porous PtCu nano-frames for enhanced ethylene glycol oxidation.

Three dimensional (3D) porous PtCu nano-frames with a unique hollow structure were obtained after a galvanic replacement reaction, exhibiting a high normalized mass activity of 23.1 A m-2 μg-1 towards ethylene glycol oxidation with excellent stability. The morphological evolution and catalytic mechanism were detailed.

A New Surgical Method to Reconstruct the Fingertip.

Background: In our previous study, we used cross finger fascial flap combined with split-thickness toe nail bed graft to reconstruct large area defect of the nail bed with distal phalanx exposure. Fingertip avulsions are common injuries to the upper extremity and cause a great deal of distress for patients. Replantation, amputation and flap coverage are considered.

Decorin as a prognostic biomarker in patients with malignant peripheral nerve sheath tumors.

Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive soft-tissue sarcomas. The prognosis of MPNSTs has been reported to differ among previous studies. However, there have been a number of reported prognostic biomarkers associated with MPNSTs.

End-to-side neurotization with the phrenic nerve in restoring the function of toe extension: an experimental study in a rat model.

The phrenic nerve being transferred to the posterior division of the lower trunk with end-to-end neurorrhaphy is reported to be effective in restoring the function of digit extension in literature. However, the phrenic nerve is extremely important in respiration. We designed an animal experiment to discover whether the phrenic nerve being transferred to the posterior division of the lower trunk with end-to-side neurotization was feasible and provided the theoretical basis.

Large malignant granular cell tumor with suprascapular nerve and brachial plexus invasion: A case report and literature review.

Rationale: Malignant granular cell tumor is a kind of rare and highly aggressive malignant tumor that commonly occurs in lower extremity, trunk, and peritoneal cavity. Huge malignant granular cell tumor (MGCT) with suprascapular nerve and brachial plexus invasion was extremely rare.

Patient Concerns: We present a special case of a 48-year-old orthopedist who suffered from MGCT.

Reconstruction of large area defect of the nail bed by cross finger fascial flap combined with split-thickness toe nail bed graft: A new surgical method.

Fingertip injury commonly results in avulsion of the nail bed. For large area defects of the nail bed with distal phalanx exposure, methods for reconstruction of soft tissue defects are scarcely mentioned in the literature.From May 2014 to January 2016, 6 patients with large area defects of the nail bed with distal phalanx exposure were enrolled.

Outcome Comparison of Nerve Transfer with Different Donor Nerves in a Rat Model.

Objective: The phrenic nerve and the contralateral seventh cervical (C7) nerve root are the most commonly used donor nerves in the treatment of total brachial plexus avulsion. The aim of this study was to determine if the phrenic nerve or the contralateral C7 nerve root yields a superior outcome for nerve transfer.

Methods: A total of 60 Sprague-Dawley rats were randomly assigned to 1 of 3 groups.

Large cervicothoracic myxoinflammatory fibroblastic sarcoma with brachial plexus invasion: A case report and literature review.

Myxoinflammatory fibroblastic sarcoma is a rare sarcoma that develops in patients of all ages, which usually presents as a slow-growing painless mass in the distal extremities. To date, myxoinflammatory fibroblastic sarcoma with invasion of the brachial plexus has rarely been reported in the literature. In this study, a case of large cervicothoracic sarcoma, which invaded the brachial plexus, is presented.

Primary Brachial Plexus Tumors: Clinical Experiences of 143 Cases.

Objective: Primary brachial plexus tumors are extremely rare and the treatment is challengeable. Our aim is to share the experiences in the treatment of primary brachial plexus tumors.

Methods: A retrospective analysis of 143 patients with primary brachial plexus tumors was made in our department from January 2001 to December 2012.

Pronator teres branch transfer to the anterior interosseous nerve for treating C8T1 brachial plexus avulsion: an anatomic study and case report.

Background: The treatment of C8T1 avulsion is challenging for neurosurgeons. Various methods for the restoration of finger flexion are used. However, most of these methods have different disadvantages and cannot restore the full active range of motion of the fingers.
