Efficacy of neuroendoscopic-assisted surgery in the management of symptomatic sacral perineural (Tarlov) cysts: a technical report.

Introduction: The Tarlov cysts are pathological enlargements of the cerebrospinal fluid spaces between the endoneurium and perineurium, which can cause intolerable sciatic pain, motor impairment of lower limbs, and bladder/bowel dysfunction. Currently, the treatment results are unsatisfactory due to the low cure rates and extensive surgical trauma. Thus, there is an ongoing exploration of surgical techniques for Tarlov treatment.

Syringo-Subarachnoid Shunt with Tube Versus T-Tube via the Dorsal Root Entry Zone Approach for Eccentric Syringomyelia.

Objective: This study compared the clinical therapeutic efficacy of syringo-subarachnoid shunt placement with direct tube and T-tube via the dorsal root entry zone (DREZ) approach for treatment of eccentric syringomyelia.

Methods: A retrospective study was performed of 41 patients with idiopathic or secondary eccentric syringomyelia from November 2011 to December 2022. Syringo-subarachnoid shunt placement with direct tube or T-tube via the DREZ approach was performed.

Air pollution and temperature are associated with increased COVID-19 incidence: A time series study.

Objectives: Although COVID-19 is known to be caused by human-to-human transmission, it remains largely unclear whether ambient air pollutants and meteorological parameters could promote its transmission.

Methods: A retrospective study was conducted to study whether air quality index (AQI), four ambient air pollutants (PM, PM, NO and CO) and five meteorological variables (daily temperature, highest temperature, lowest temperature, temperature difference and sunshine duration) could increase COVID-19 incidence in Wuhan and XiaoGan between Jan 26th to Feb 29th in 2020.

Results: First, a significant correlation was found between COVID-19 incidence and AQI in both Wuhan (R=0.

Prevalence of stress and its determinants among residents enrolled in China Standardized Training Program for Resident Doctor (C-STRD) program: A cross-sectional study.

Background: It has been widely understood that well-trained doctors are crucial for a high-quality public health system and safe patient care. Thus, in 2011, China initiated its first national residency training program, called the China Standardized Training for Resident Doctor (C-STRD), for medical graduates to prepare qualified doctors for the medical care system with increasing demands. So far, no studies have specifically address the prevalence of stress and its determinants among residents enrolled in the C-STRD.

Distinct roles of neuregulin in different models of neuropathic pain.

The objective of the study was to investigate the role of neuregulin-ErbB signaling in neuropathic pain in different types of injury. Neuregulin-1(NRG-1) was injected into animals with either formalin-induced pain model or spared nerve injury (SNI) model. Formalin tests or paw withdrawal tests were performed to study the role of NRG-1 in neuropathic pain.

[Effect of local mild hypothermia on expression of aquaporin-4 following intracerebral hemorrhage in rats].

Objective: To examined the effect of local mild hypothermia on the expression of aquaporin-4 (AQP-4) following intracerebral hemorrhage (ICH) in rats and clarified the mechanism of hypothermia on brain edema formation following ICH.

Methods: Two hundreds and forty male Wistar rats were randomly divided into two groups: the intracerebral hemorrhage (ICH) group, in which autologous arterial blood were stereotaxically injected into right caudate nucleus; the local mild hypothermia (ICH + H) group, in which the rats were given 4 h local mild hypothermia after the injection of blood. Each group was divided into 6 subgroups: control, 6 h, 24 h, 72 h, 5 d and 7 d after operation; Brain water content was determined by dry-wet weight method and the permeability of BBB was measured by Evans-Blue extravasation.
