AIM To assess the efficacy and safety of fibrin sealant for closure of mucosal penetration at the cardia during peroral endoscopic myotomy(POEM).METHODS Twenty-four patients who underwent POEM and experienced mucosal injury of the cardia during the procedure were retrospectively identified. Of the 24 patients, 21 had mucosal penetration and 3 had only slight mucosal damage without penetration. The 21 patients with mucosal penetration received fibrin sealant for closure at the site of penetration. Penetration-related characteristics, treatment, and recovery were reviewed for all 21 patients to assess the efficacy and safety of fibrin sealant for closure of mucosal penetration at the cardia. Clinical data, including general characteristics, procedure-related parameters, Eckardt scores, lower esophageal sphincter pressures (LESP), and esophagogastroduodenoscopy(EGD) results, were analyzed to determine their influence on treatment success after mucosal penetration during *** All 21 patients had a solitary mucosal penetration in the cardia (12 in esophageal region of the cardia, 9 in the stomach region of the cardia, and 1 in both the esophageal and stomach regions). Twelve had ahole-like penetration and 9 had a linear penetration. For those with a hole-like penetration, the mean size was 0.14 cm2 (0.02-0.32 cm2). For those with a linear penetration, the median size was 0.37 cm (0.10-1.00 cm). Closure of the mucosal penetration using fibrin sealant was performed successfully in all 21 patients(two patients required 5 m L fibrin sealant, and the remaining 19 patients required 2.5 mL). Two patients had a nasogastric tube placed for five days after POEM; the remaining 19 patients were kept fasting for 3 d. All 21 patients were discharged after a median of 5 d(range: 5-7 d) postoperatively. During a median 42 mo (range: 9-62 mo) follow-up, all 21 patients with a mucosal penetration successfully healed without the occurrence of infection, ulcer, or esophagitis. Furth

Abundant aggregated, elongate, shallow borings have been discovered from the Lower Cretaceous Yixian Formation in western Liaoning, China. By contrast with several similarly-shaped trace fossils, such as Asthenopodichnium, Teredolites,Rogerella, Cubiculum and Petroxestes, their appearance, size, arranged modes, distribution density and substrate types are most similar with traces of Petroxestes that was discovered from Southern Ohio, USA（J. Paleontol. 62： 306-08,1988）. This is the first report of Petroxestes from China, and also the first report of these traces from a terrestrial environment.

AIM: To evaluate the real-life clinical outcomes of intravitreal injection of conbercept combined rescue therapy for polypoidal choroidal vasculopathy(PCV). METHODS: This was an open label, single center, and interventional study. All enrolled patients were treated initially with three consecutive monthly intravitreal conbercept injections(0.5 mg). Additional conbercept injections were administered upon substantial polyp regression with improved visual acuity(VA). Eyes with partial or no polyp regression and poor VA were rescue treated with photodynamic therapy(PDT) for subfoveal polyps or thermal laser photocoagulation for extrafoveal polyps. Best-corrected visual acuity(BCVA), central foveal thickness(CFT) and polyp regression were observed as primary outcomes. Side effects were also collected during the follow-up period. RESULTS: A total of 56 eyes(56 patients) with PCV were included. BCVA increased significantly from the baseline of 43.52±24.21 letters to 55.88±21.94 letters(Pents showed polyp regression. Twenty-three eyes achieved complete polyp regression after the three initial injections, which increased to 44 eyes at 12 mo. Seventeen eyes underwent rescue therapy, among which 2 eyes treated with PDT and 15 eyes treated with laser photocoagulation. A mean of 4.30±1.43 injections were given per eye. No intraocular inflammation, retinal or vitreous hemorrhage, or systemic complication occurred. CONCLUSION: Conbercept is an effective and safe option for the treatment of PCV in Chinese population. The treatment regimen of three initial conbercept injections followed by additional injections or rescue therapies is efficacious for treating PCV.

Dear editor,Recently, finite-dimensional systems with infinitedimensional actuator or sensor dynamics have drawn the attention of researchers worldwide. Many real-world systems can be modeled as ordinary differential equation (ODE)-partial differential equation (PDE) cascade systems, such as traffic flows, chemical reactor processes, heat exchangers,and oil well drilling. In this study, we consider the problem of compensating the actuator dynamics modeled by the Euler-Bernoulli beam (EBB) equation.

This paper is concerned with a popular form of Cahn-Hilliard equation which plays an important role in understanding the evolution of phase separation. We get the existence and regularity of a weak solution to nonlinear parabolic, fourth order Cahn-Hilliard equation with degenerate mobility M(u)= u^m(1-u)^m which is allowed to vanish at 0 and 1. The existence and regularity of weak solutions to the degenerate Cahn-Hilliard equation are obtained by getting the limits of Cahn-Hilliard equation with non-degenerate mobility. We explore the initial value problem with compact support and obtain the local non-negative result. Further, the above derivation process is also suitable for the viscous Cahn–Hilliard equation with degenerate mobility.
