The neuromuscular control for lower limb exoskeleton- a 50-year perspective.

Historically, impaired lower limb function has resulted in heavy health burden and large economic loss in society. Although experts from various fields have put large amounts of effort into overcoming this challenge, there is still not a single standard treatment that can completely restore the lost limb function. During the past half century, with the advancing understanding of human biomechanics and engineering technologies, exoskeletons have achieved certain degrees of success in assisting and rehabilitating patients with loss of limb function, and therefore has been spotlighted in both the medical and engineering fields.

Resolution of type I Chiari malformation and associated syringomyelia following intrathecal chemotherapy: case report.

Type I Chiari malformation (CM-I) consists of downward herniation of the cerebellar tonsils below the foramen magnum and often requires surgical decompression if symptomatic. Spontaneous resolution of CM-I is rare. We present a case of resolved CM-I without surgery in a 6-year-old boy with B-cell lymphoma who was diagnosed with CM-I during lymphoma staging.

Research Progress of Cancer Stem Cells in Uveal Melanoma.

Uveal melanoma is the most common malignant tumor in adult eyes, mostly in the choroid, but also in the iris and ciliary body. Distant metastasis is found in nearly half of the patients. Cancer stem cells are a kind of cells with the ability of self-renewal and multidirectional differentiation, which are related to tumor invasion and metastasis.

Choroidal vascular changes in retinitis pigmentosa patients detected by optical coherence tomography angiography.

Background: To evaluate choroidal vascular changes, including choriocapillaris (CC) and middle/large choroidal vessels, in retinitis pigmentosa (RP) patients using wide-angle optical coherence tomography angiography (OCTA) and to determine whether changes in the choroidal vascularity have a relationship with visual function and retinal structural changes.

Methods: 34 patients with a confirmed diagnosis of RP and 48 controls were recruited. All patients underwent detailed ophthalmologic and imaging examinations, including two types of OCTA (Optovue, 3 × 3 mm, 6 × 6 mm; VG-200, 12 × 12 mm).

The role of sacral laminoplasty in the management of spina bifida and sacral cystic lesions: case series.

Objective: Although laminae are not viewed as essential structures for spinal integrity, in the sacrum the anatomical weakness and gravity makes it a vulnerable area for CSF accumulation and expansion. The congenital or postoperative defects of sacral laminae, such as in patients with spina bifida, make this area more susceptible to forming progressive dural ectasia, pseudomeningocele, or expansile arachnoid cyst (Tarlov cyst). In addition, adhesions between the dura and surrounding soft tissue after laminectomy can cause some local symptoms, which are difficult to relieve.

The protective effect of asiatic acid on podocytes in the kidney of diabetic rats.

The essential ingredient of Centella asiatic is asiatic acid (AA). There are a lot of biological activities in AA, such as anti-oxidant, anti-diabetic. However, so far, there have been no reports on the underlying protective mechanism of AA on podocytes.

Is the chiasm-pituitary corridor size important for achieving gross-total resection during endonasal endoscopic resection of craniopharyngiomas?

OBJECTIVE Craniopharyngiomas arise from the pituitary stalk, and in adults they are generally located posterior to the chiasm extending up into the third ventricle. The extended endonasal approach (EEA) can provide an ideal corridor between the bottom of the optic chiasm and the top of the pituitary gland (chiasm-pituitary corridor [CPC]) for their removal. A narrow CPC in patients with a prefixed chiasm and a large tumor extending up and behind the chiasm has been considered a contraindication to EEA, with a high risk of visual deterioration and subtotal resection.

Transorbital endoscopic eyelid approach for resection of sphenoorbital meningiomas with predominant hyperostosis: report of 2 cases.

Sphenoorbital meningiomas (SOMs) are slow-growing tumors that originate from the sphenoidal wing and are associated with visual deterioration, extrinsic ocular movement disorders, and proptosis caused by hyperostosis of the lateral wall of the orbit. In some cases, the intracranial component is quite small or "en plaque," and the majority of the symptoms arise from adjacent hyperostosis. Craniotomy has traditionally been the standard of care, but new minimally invasive multiportal endoscopic approaches offer an alternative.

Reoperation for growth hormone-secreting pituitary adenomas: report on an endonasal endoscopic series with a systematic review and meta-analysis of the literature.

OBJECTIVE Surgery is generally the first-line therapy for acromegaly. For patients with residual or recurrent tumors, several treatment options exist, including repeat surgery, medical therapy, and radiation. Reoperation for recurrent acromegaly has been associated with poor results, with hormonal control usually achieved in fewer than 50% of cases.
