BACKGROUND:Beginning in the 2020 spring semester, due to COVID-19 pandemic, all school-age children China were homeschooled via live/recorded broadcasts, online group communication, and software-based homework submission. This study assessed effects of proper preparation for this educational approach. MATERIAL AND METHODS:The homeschooling behaviors feelings with 2010 surveys obtained separately from students, parents, teachers grades 1–9 15 Chinese provinces. Answers compared among low-...

BACKGROUND: Postoperative cognitive dysfunction (POCD) can be a debilitating complication after coronary artery bypass graft (CABG) surgery. Cerebral microemboli during cardiopulmonary (CPB) are believed to an important etiologic factor of POCD. In this study, we examined whether avoidance CPB with "off-pump" surgery reduces the number cerebral and incidence POCD CABG in Chinese population. METHODS: Two hundred twenty-seven patients were enrolled prospective cohort study. Fifty-nine...

Currently, various calculation methods for evaluating blood-loss in patients with total knee arthroplasty (TKA) are applied clinical practice. However, different may yield results. The purpose of this study was to determine the most reliable method calculating after primary TKA. We compared 245 who underwent unilateral TKA from February 2010 August 2011. calculated using four methods: Gross equation, hemoglobin (Hb) balance, Orthopedic Surgery Transfusion Hemoglobin European Overview...

As a new widespread contaminant, nanoplastics (NPs) pose potential risk to human health. Nevertheless, the adverse effects of NPs on male reproductive system are poorly understood. In this study, we aimed determine polystyrene (PS-NPs) (50 nm) sperm quality, with focus acrosome defects. After 35 days intragastric administration, quality was decreased and testicular structures were impaired in mice exposed PS-NPs both medium (1.0 mg/kg) high dose (10 groups. No significant changes observed...

Ginger has long been used as an alternative medication to prevent motion sickness. The mechanism of its action, however, is unknown. We hypothesize that ginger ameliorates the nausea associated with sickness by preventing development gastric dysrhythmias and elevation plasma vasopressin. Thirteen volunteers a history underwent circular vection, during which (scored 0–3, i.e., none severe), electrogastrographic recordings, vasopressin levels were assessed or without pretreatment in...

AbstractBackground: Loperamide improves anorectal function in patients with chronic diarrhoea. We wished to investigate whether the prodrug loperamide oxide has similar effects. Methods: Eleven diarrhoea and faecal incontinence participated a randomized, placebo-controlled, double-blind, crossover study of effects (4 mg twice daily for 1 week). Results: reduced wet stool weight improved patients' ratings symptoms. Mouth-to-caecum transit time was not altered, but whole-gut prolonged. There...

Coexposure of nanoplastics (NPs) with other pollutants adsorbed from the surroundings has received extensive attention. Currently, combined effects NPs and plasticizers remain unclear. Di-(2-ethylhexyl) phthalate (DEHP) is a commonly used plasticizer that raised much concern owing to its ubiquitous pollution endocrine-disrupting potential. This study aimed investigate toxic on male reproductive system upon coexposure DEHP. The C57BL/6J mice were orally administrated polystyrene nanoparticles...

Anorectal manometry and sphincter electromyography were performed in 23 patients with complete supraconal traumatic spinal injuries 30 age sex matched control subjects. Basal pressures the group similar to those normal subjects but conscious of activity was abolished all patients. Discriminant rectal sensation also during distension, 40% experienced a dull pelvic ache at maximum levels distension. Phasic contraction anal relaxation present exaggerated induced lower distending volumes than...

Hyperglycemia slows gastric emptying in normal individuals and patients with diabetes mellitus may affect both somatic visceral sensation. The effects of hyperglycemia on proximal motility sensation during intraduodenal infusion a triglyceride emulsion were evaluated using barostat six subjects euglycemia (approximately 15 mmol/l). Isobaric distension induced greater bag volumes compared at 3 (452 +/- 26 vs. 343 12 ml, P< 0.05) 4 mmHg (600 55 497 50 P < above basal pressure. During...

A combined manometric and ultrasonographic study of the internal anal sphincter was carried out in 20 patients with haemorrhoids age-matched normal controls. Mean(s.e.m.) basal pressure significantly higher than controls, 62(4) versus 45(6) cmH2O (P less 0.05), although there were no significant differences mean maximum squeeze pressures. During rectal distension 90 per cent showed reduction outermost channel, electromyogram suppressed external did not necessarily increase above baseline....

Abstract Anorectal manometry and electrophysiology studies were conducted in 25 men with non-prolapsing haemorrhoids, ten prolapsing 20 age-matched normal men. Mean(s.e.m.) minimum basal pressures significantly higher patients haemorrhoids than normals (61(5) versus 43(7) cmH2O; P < 0·05) or (55(4) 0·05). There no significant differences maximum squeeze pressures. During rectal distension, all subjects showed relaxation anal channels. However, 92 per cent of 40 the outer channels,...
