Effects of Appropriate Prolonged Sacral Neuromodulation Testing in Improving Implantation Rate of a Permanent Implantable Pulse Generator in Patients with Refractory Lower Urinary Tract Dysfunctions in Mainland China.
Sacral neuromodulation (SNM) has become an effective method for treating lower urinary tract voiding dysfunction during the past 20 years. Because of the expensive cost, the number of implantable pulse generator (IPG) implantations per year in China is far lower than that in Western developed countries since 2012. This study was to summarize the effects of the appropriate prolonged SNM testing time in improving the implantation rate of a permanent IPG in patients with refractory lower urinary tract symptoms (LUTS) in mainland China. ⋯ Appropriate extension of the Stage I testing time of an SNM-barbed electrode could significantly improve the Stage II permanent implantation rate in Chinese refractory LUTS patients; there were no wound infections, and the postoperative complication rate was low. This study recommended that Stage I period of SNM therapy should be 4 weeks according to safety and successful conversion rate.

Efficacy and Safety of the WATCHMAN Left Atrial Appendage System for Stroke Prevention in Chinese Patients with Nonvalvular Atrial Fibrillation: A Single-center, Prospective, Observational Study.
In patients with nonvalvular atrial fibrillation (NVAF), embolic stroke is thought to be associated with left atrial appendage (LAA) thrombi. The WATCHMAN LAA Occlusion Device has been shown to be noninferior to conventional oral anticoagulation with warfarin for stroke prevention in patients with NVAF. This study aimed to evaluate the procedural feasibility, safety and 12-month outcomes of the WATCHMAN LAA Occlusion Device in NVAF patients with high risk for stroke in China. ⋯ LAA closure with the WATCHMAN Device was feasible, efficient, and safe for NVAF to prevent the accidence of stroke in Chinese patients. During the 12-month follow-up period, the observed ischemic stroke rate (2.0% per year) in our study was lower than the predicted annual stroke risk (4.0%) using the CHA2DS2-VASc score.

Laryngeal Mask Airway for Cesarean Delivery: A 5-Year Retrospective Cohort Study.
The laryngeal mask airway (LMA) is the most commonly used rescue airway in obstetric anesthesia. The aim of this retrospective cohort study was to evaluate the application of the LMA in parturients undergoing cesarean delivery (CD) for 5 years in our hospital. As a secondary objective, we investigated the incidence of airway-related complication in obstetric general anesthesia (GA). ⋯ Our results suggested that GA was mainly used for contraindication to neuraxial anesthesia or a failed block, and emergent CDs accounted for most cases. The second-generation LMA could be used for obstetric anesthesia, but correct position to achieve a good seal is the key to prevent reflux and aspiration. Whether they could replace the tracheal tube in routine practice needs further large prospective studies.

Morphological changes of the vasculature system in patients with myopia have been observed by Doppler ultrasound and fundus fluorescein angiography (FFA); however, these studies have limitations. Doppler ultrasound provides low-resolution images which are mainly obtained from visualized large vessels, and FFA is an invasive examination. Optic coherence tomography (OCT) angiography is a noninvasive, high-resolution measurement for vascular density. The purpose of this study was to investigate the change of vascular density in myopic eyes using OCT angiography. ⋯ Our results suggested that with the increase of myopia, the vascular density decreased in macular region, but not in optic disc region.
