This is the first to report follow up at 1 year.
Both MRI and exam showed no evidence of recurrent disease at one year follow up. This report aims to further the understanding of Secretory Carcinoma tumours in the sinuses. Our report could be used to further understand diagnostic criteria for Secretory Carcinoma in the sinuses as well as treatment outcomes for surgical resection without adjuvant treatment.

A 50-year-old female presented out of hours with an acute, 16-h history of complete left sided visual loss, on a background of 3 days of visual changes. A left ethmoid mucocoele extending into the left orbital apex causing compression of the optic nerve was diagnosed on imaging. Emergency endoscopic sinus surgery with decompression and marsupialization of the ethmoid mucocoele was performed, which resulted in improvement of vision. This case is unusual due to improvement in vision despite the length of visual loss prior to surgical intervention. This case demonstrates the importance of considering rhinological causes for vision loss, and how critical early identification and surgical intervention can be to prevent serious complications such as permanent vision loss.
Huge intramedullary tumor is a rare condition. Surgical management of such huge ependymoma is technically challenging. We reported one case of 300 mm long intramedullary spinal cord ependymoma from oblongata to T4, which was satisfactorily en bloc gross total resected and the cervical spine alignment was successfully maintained by laminoplasty.
A 30-year-old man presented to our service with two-year progressive neck pain combined with bilateral sense disorders of both the upper and lower extremities. The neurological grade was ASIA D. Repeat MRI imaging demonstrated a "medulla oblongata to T4" intramedullary spinal cord tumor complicated with cervical physiological curvature loss.
Laminectomies were made at the C1-T4 level by a milling cutter. The tumor was gently separated bilaterally. The ventral part of the tumor was separated from the cranial and the caudal ends until reaching the middle site of the tumor. The whole tumor was isolated en bloc. ACY-775 Titanium miniplates were used bilaterally to fix both sides of the laminoplasty section on each level. At the 2-year postoperative follow-up, the muscle strength of both the upper and lower limbs were grade Ⅳ. No tumor recurrence was detected.
The total removal of an intramedullary ependymoma should be recommended as soon as the diagnosis is made, regardless of its extension. Long-level laminoplasty could be an effective alternative option to maintain the proper spine alignment.

Pheochromocytoma surgery is generally challenging for surgeons and anesthesiologists for cardiovascular complications.
A 54-year-old Japanese man was found to have a large right pheochromocytoma infiltrating the posterior part of his liver and vena cava and multiple lung metastases. After retroperitoneal laparoscopic dissection of the dorsal side of the tumor and ligation of the feeding vessels, total resection of the primary tumor, extended posterior sectional hepatectomy, and partial vena cava resection were performed by open surgery via a thoracoabdominal approach. Abundant congestive bleeding with instability of vital signs occurred during transection. It could be finally controlled by dissect the remnant feeding artery in the inmost space. Prior control of arterial in-flow enabled successful completion of the planned surgical procedure. The patient has now survived for 27 months since resection of the primary lesion.
Ligation of the feeding arteries to this hypervascular catecholamine-releasing tumor via a retroperitoneal laparoscopic approach prior to performing combined organ resection facilitated successful excision of this large malignant pheochromocytoma.

NADPH oxidase activity results in formation of H2O2, that, in turn, sets cellular redox status, a key regulator of cellular homeostasis and responses to external stimuli. Hydrogen peroxide metabolism regulates cell redox status by driving changes in protein cysteine oxidation often via cycling of thioredoxin/peroxiredoxin and glutathione; however, regulation of enzymes controlling synthesis and utilization of H2O2 is not understood beyond broad outlines. The data presented here show that calcium-stimulated epithelial Duox H2O2 synthesis is transient, independent of intracellular calcium renormalization, H2O2 scavenging by antioxidant enzymes, or substrate depletion. The data support existence of a separate mechanism that restricts epithelial H2O2 synthesis to a burst and prevents harmful changes in redox tone following continuous stimulation. Elucidation of this H2O2 synthesis tempering mechanism is key to understanding cellular redox regulation and control of downstream effectors, and this observation provides a starting point for investigation of the mechanism that controls H2O2-mediated increases in redox tone.China has approximately 10 million people with epilepsy. There is a vast epilepsy treatment gap in China, mainly driven by deficiencies in health-care delivery and social discrimination resulting from cultural beliefs about epilepsy. WHO's Global Campaign Against Epilepsy project in China showed that it was possible to treat epilepsy in primary care settings, which was a notable milestone. The China Association Against Epilepsy has been a necessary force to stimulate interest in epilepsy care and research by the medical and scientific community. Nearly 20 different anti-seizure medications are now available in China. Non-pharmacological options are also available, but there are still unmet needs for epilepsy management. The Chinese epilepsy research portfolio is varied, but the areas in which there are the most concentrated focus and expertise are epidemiology and clinical research. The challenges for further improvement in delivering care for people with epilepsy in China are primarily related to public health and reducing inequalities within this vast country.
