Case Report: Snake Venom Ophthalmia Caused by Cobra Exposure: A Report of 26 Cases.

We report 26 cases of eye injuries resulting from cobra venom sprayed by Naja atra. This accounts for 14.5% of patients (26/173) treated for cobra injuries who presented to the emergency department of a snakebite treatment center in Guangzhou, South China.

Proteomic characteristics of six snake venoms from the Viperidae and Elapidae families in China and their relation to local tissue necrosis.

Patients envenomed by snakes from the Viperidae and Elapidae families in China often have varying degrees of local tissue necrosis. Due to the relative clinical characteristics of local tissue necrosis and ulceration following envenoming, this study has analyzed the proteome of six snake venoms from the Viperidae and Elapidae family, and the toxin profiles of each snake were compared and correlated with the clinical manifestations that follow cytotoxic envenoming. Deinagkistrodon acutus and Naja atra envenomation induce severe ulceration, which is absent in Bungarus multicinctus envenomation and mild in the other three vipers.

Intra-operative optical coherence tomography in corneal lamellar graft reinforcement for Boston type I keratoprosthesis corneal melt.

Corneal melt is a sight-threatening complication of Boston type 1 keratoprosthesis (KPro). Severe corneal melt may result in hypotony, choroidal hemorrhage, and even spontaneous extrusion of the KPro, which may lead to a poor visual prognosis. Lamellar keratoplasty is one surgical option for the management of mild corneal melt, especially when a new KPro is not available.

Pediatric Chemical and Thermal Ocular Injuries Requiring Hospitalization in South China.

Purpose: To study the clinical characteristics of children with severe ocular chemical or thermal injuries in South China and evaluate prognostic factors affecting final visual acuity (VA).

Methods: A five-year retrospective study was conducted on pediatric patients who were first admitted to Zhongshan Ophthalmic Center with severe chemical or thermal ocular injuries. Data collected and analyzed comprised socioeconomic and socio-demographic data, details regarding their injury, subsequent treatment, and visual outcomes.

Effectiveness of clotting factor replacement therapy after antivenom treatment on coagulopathic envenomation following green pit viper bites: a retrospective observational study.

Background: Green pit vipers (GPVs), namely Trimeresurus albolabris and Trimeresurus stejnegeri accounts for most snakebites in Southern China. Green pit viper venom contains thrombin-like enzymes, resulting in defibrination syndrome. Using of clotting factor replacement after antivenom administration is controversial.

Clinical Experience in Patients with Ocular Burns Treated with Boston Type I Keratoprosthesis Implantation with or Without Prophylactic Ahmed Glaucoma Valve Implantation.

Introduction: To compare outcomes in eyes with ocular burns following Boston Type I keratoprosthesis (KPro) implantation with and without prophylactic pars plana tube surgery.

Methods: A retrospective review of patients with ocular burns who underwent KPro surgery at Zhongshan Ophthalmic Center was performed. Twenty-six eyes of 26 patients without a preoperative diagnosis of glaucoma before KPro surgery met the inclusion criteria.

Prone versus Supine Position Ventilation in Adult Patients with Acute Respiratory Distress Syndrome: A Meta-Analysis of Randomized Controlled Trials.

The purpose of this meta-analysis was to compare the efficacy and safety of prone versus supine position ventilation for adult acute respiratory distress syndrome (ARDS) patients. The electronic databases of PubMed, Embase, and the Cochrane Library were systematically searched from their inception up to September 2020. The relative risks (RRs) and weighted mean differences (WMDs) with corresponding 95% confidence intervals (CIs) were employed to calculate pooled outcomes using the random-effects models.

Impacts of a Specific Cyclooxygenase-2 Inhibitor on Pressure Overload-Induced Myocardial Hypertrophy in Rats.

Objective: The aim of this study was to observe the impacts of the specific cyclooxygenase-2 inhibitor celecoxib on cardiac structures, functions, and inflammatory factors during the process of pressure overload-induced myocardial hypertrophy.

Methods: Twenty-four male Sprague Dawley rats were randomly divided into 3 groups: the sham operation group, the surgery group, and the celecoxib group. The model was established according to the abdominal aortic coarctation method.

Comparing the efficacy of bag-valve mask, endotracheal intubation, and laryngeal mask airway for subjects with out-of-hospital cardiac arrest: an indirect meta-analysis.

Background: For subjects with out-of-hospital cardiac arrest (OHCA), bag-valve mask (BVM), endotracheal intubation (ETI), and laryngeal mask airway (LMA) are the most common methods of ventilatory support; however, the best choice remains controversial.

Methods: A comprehensive search of online databases was performed. A traditional meta-analysis was performed to determine the risk ratio of BVM LMA and ETI LMA.

Effect of Zhenwu Tang Granule on pressure-overloaded left ventricular myocardial hypertrophy in rats.

Background: In the perspective of traditional Chinese medicine, few studies have focused on the compound preparations though there are many investigations. The present study was undertaken to investigate the effect of Zhenwu Tang Granule on chronic pressure-overloaded left ventricular hypertrophy in rats.

Methods: The study was performed at the laboratory of Guangzhou Institute of Respiratory Disease.
