·AIM:To evaluate the role of internal limiting membrane(ILM)peeling in preventing secondary epiretinal membrane(ERM)formation in pars plana vitrectomy(PPV)for proliferative diabetic retinopathy(PDR).·METHODS:This retrospective study analyzed the medical records of patients who underwent PPV for PDR and were followed up for minimum 3 *** peeling was performed based on the intraoperative surgeons’*** was assessed by optical coherence tomography *** relationship between ILM peeling and postoperative ERM was analyzed.·RESULTS:In total,212 eyes from 197 patients were included in this *** incidence of secondary ERM in the ILM non-peeling group was significantly higher than that in the ILM peeling group(37.0%vs 14.0%;P<0.001).Multivariate logistical regression revealed that ILM peeling was highly associated with the prevention of secondary ERM development[odds ratio 0.38;95%confidence interval0.17-0.86;P<0.05].·CONCLUSION:ILM peeling during PPV for PDRs can effectively reduce the incidence of secondary ERM development and is worth consideration by vitreoretinal surgeons.

AIM： To report the results of rhegmatogenous retinal detachment（RRD） repair after pars plana vitrectomy（PPV） without operative use of heavy liquid, and utilizing air tamponade in selected ***： RRD patients without severity of proliferative vitreoretinopathy C2 or more underwent PPV without operative use of heavy liquid, and utilizing air tamponade were consecutively enrolled. Alternative postoperative facedown position or lateral position was required for 3-5 ***： Totally 36 eyes of 36 patients（24 males, 66.7%） aged 53.8±10.9 y underwent this modified surgery. The mean number of retinal break was 2.1±1.3. Most of the eyes（29, 80.6%） had retinal detachment involving more than one quadrant. Twenty-two（61.1%） eyes with cataract had combined phacoemulsification and intraocular lens implantation. The mean follow up time was 4.6±1.8 mo. Two eyes with retinal redetachment underwent a second retinal repair surgery with silicone oil tamponade, yielding the primary reattachment rate to 94.4%（34/36）. Six（16.7%） eyes had intraocular pressure higher than 25 mm Hg. The visual acuity（logMAR） improved from 0.98±0.74 preoperatively to 0.52±0.31 postoperatively（P〈0.001）. CONCLUSION： The success rate of this modified retinal repair surgery is comparable with traditional surgery. This technique can be considered for certain retinal detachment patients, since its apparent advantages included lower surgical complications, reduced surgery expenditure, shorter time for postoperative facedown position, and avoiding silicone oil removal surgery.

In this paper, we explore state-based potential games using the semi-tensor product of ***, applying the potential equation, we derive both a necessary and sufficient condition as well as a sufficient condition to verify whether a state-based game qualifies as a potential game. Next, we present two static equivalence conditions of state-based potential games. We then delve into dynamic equivalence. We propose a criterion that allows us to identify state-based games that are dynamically equivalent to state-based potential games and share similar dynamic properties. Ultimately, we introduce the concept of state-based networked evolutionary games. We provide a necessary and sufficient condition to ensure that a state-based networked evolutionary game can be classified as a state-based potential game.

Our understanding of pre-Cretaceous dinosaur reproduction is hindered by a scarcity of evidence within fossil records. Here we report three adult skeletons and five clutches of embryo-containing eggs of a new sauropodomorph from the Lower Jurassic of southwestern China, displaying several significant reproductive features that are either unknown or unlike other early-diverging sauropodomorphs, such as relatively large eggs with a relatively thick calcareous shell formed by prominent mammillary cones, synchronous hatching and a transitional prehatching posture between the crocodilians and living birds. Most significantly,these Early Jurassic fossils provide strong evidence for the earliest known leathery eggs. Our comprehensive quantitative analyses demonstrate that the first dinosaur eggs were probably leathery, elliptical and relatively small, but with relatively long eggshell units, and that along the line to living birds, the most significant change in reptilian egg morphology occurred early in theropod evolution rather than near the origin of Aves.
