Increased peripheral leukocyte aggravates brain injury and leads to poor outcome in stroke patients receiving intravenous thrombolysis: A study based on clinical evidence.

Whether the dynamic development of peripheral inflammation aggravates brain injury and leads to poor outcome in stroke patients receiving intravenous thrombolysis (IVT), remains unclear and warrants further study. In this study, total of 1034 patients with acute ischemic stroke who underwent IVT were enrolled. Serum leukocyte variation (whether increase from baseline to 24 h after IVT), National Institutes of Health Stroke Scale (NIHSS), infarct volume, early neurologic deterioration (END), the unfavorable outcome at 3-month (modified Rankin Scale [mRS] score ≥3) and mortality were recorded.

Integrated High-Performance Infrared Phototransistor Arrays Composed of Nonlayered PbS-MoS Heterostructures with Edge Contacts.

Molybdenum disulfide (MoS) has attracted a great deal of attention in optoelectronic applications due to its high mobility, low off-state current and high on/off ratio. However, its intrinsic large bandgap limits its application in infrared detection. Here, we have developed a high-performance infrared photodetector by integrating nonlayered PbS and layered MoS nanostructures via van der Waals epitaxy.

Clinical importance of surgical treatment of low rectal carcinoma in anus-preserving procedure--an analysis of 86 cases.

We investigated the methods and experiences of an anus-preserving procedure in curative resection of low rectal carcinoma. Eighty-six patients with low rectal carcinoma underwent Dixon's procedure with device assistance. Patients were then observed for the effects of operation.
