Vitrectomy combined with internal limiting membrane peeling (ILMP) treats high myopic foveoschisis with good results, but there is a risk of iatrogenic macular holes, which may be reduced by preserving the internal limiting membrane of the central fovea. This study compared complete ILMP with partial ILMP, both combined with 25G vitrectomy, for the treatment of high myopic foveoschisis.Thirty-three cases (33 eyes) of high myopic foveoschisis were retrospectively analyzed. They underwent 25G vitrectomy combined with C3F8 gas filling; Group A (20 patients, 20 eyes) underwent complete ILMP, while Group B (13 patients, 13 eyes) underwent partial ILMP to preserve the internal limiting membrane of the central fovea. Patients were followed up for 6 months and underwent best corrected visual acuity (BCVA), intraocular pressure, diopter, slit lamp microscopy, indirect ophthalmoscope, A-mode and/or B-mode ultrasound, and optical coherence tomography. Surgical complications were recorded.Up to the last follow-up, the BCVA improved and central fovea thickness (CFT) was lower compared with before surgery in both groups (All P < .05). There were no significant differences in BCVA and CFT at each time point between the groups (P > .05). Most of the postoperative retinas of the 2 groups were completely reattached, with disappearance of the macular retinoschisis cavity. Two patients in the Group A and none in the Group B developed a macular hole during follow-up (P = .508).The results did not support the superiority of partial ILMP over complete ILMP in reduced incidence of macular hole. Both methods had a similar curative effect.

The cells and tissue in the human body are orderly and directionally arranged, and constructing an ideal biomimetic extracellular matrix is still a major problem to be solved in tissue engineering. In the field of the bioresorbable vascular grafts, the long-term functional prognosis requires that cells first migrate and grow along the physiological arrangement direction of the vessel itself. Moreover, the graft is required to promote the formation of neointima and the development of the vessel walls while ensuring that the whole repair process does not form a thrombus. In this study, poly (l-lactide-co-ε-caprolactone) (PLCL) shell layers and polyethylene oxide (PEO) core layers with different microstructures and loaded with sodium tanshinone IIA sulfonate (STS) were prepared by coaxial electrospinning. The mechanical properties proved that the fiber membranes had good mechanical support, higher than that of the human aorta, as well as great suture retention strengths. The hydrophilicity of the oriented-fiber membranes was greatly improved compared with that of the random-fiber membranes. Furthermore, we investigated the biocompatibility and hemocompatibility of different functional fiber membranes, and the results showed that the oriented-fiber membranes containing sodium tanshinone IIA sulfonate had an excellent antiplatelet adhesion effect compared to other fiber membranes. Cytological analysis confirmed that the functional fiber membranes were non-cytotoxic and had significant cell proliferation capacities. The oriented-fiber membranes induced cell growth along the orientation direction. Degradation tests showed that the pH variation range had little change, the material mass was gradually reduced, and the fiber morphology was slowly destroyed. Thus, results indicated the degradation rate of the oriented-fiber graft likely is suitable for the process of new tissue regeneration, while the random-fiber graft with a low degradation rate may cause the material to reside in the tissue for too long, which would impede new tissue reconstitution. In summary, the oriented-functional-fiber membranes possessing core–shell structures with sodium tanshinone IIA sulfonate/polyethylene oxide loading could be used as tissue engineering materials for applications such as vascular grafts with good prospects, and their clinical application potential will be further explored in future research.

Electroencephalogram (EEG) data depict various emotional states and reflect brain activity. There has been increasing interest in EEG emotion recognition in brain–computer interface systems (BCIs). In the World Robot Contest (WRC), the BCI Controlled Robot Contest successfully staged an emotion recognition technology competition. Three types of emotions (happy, sad, and neutral) are modeled using EEG signals. In this study, 5 methods employed by different teams are compared. The results reveal that classical machine learning approaches and deep learning methods perform similarly in offline recognition, whereas deep learning methods perform better in online cross-subject decoding.

In this study, a generalized fuzzy chance constrained programming method is developed for the energy system planning in Guangzhou under multiple uncertainties. Through integrating the generalized fuzzy programming and chance-constrained programming into an inexact optimization framework, this method can handle uncertainties expressed as probability distributions, fuzzy sets and fuzzy random variables. Solutions of energy supply, power generation, capacity expansion, air pollutant emissions, forest planning, and system cost under different levels of α-cut are obtained considering the constraint violation risk. The results show that the consumption of coal will decline gradually, while natural gas will become the main source of energy supply in the future; the power structure of the city changes from coal to clean energy (e.g., solar, wind, hydro and other renewable energy), and the city's energy supply security is enhanced by stimulating the utilization of renewable energy and reducing the utilization of imported energy. Moreover, a rational use of ecological land is of great significance. Forests can absorb carbon dioxide and will play a positive role in reducing greenhouse effects. When the preferred α value is predetermined by the decision makers, the energy selections can also be obtained directly from the resulting fuzzy membership function. The solutions obtained in the study will help managers to optimize the existing city energy structure, 2 make decisions according to different preferences between system cost and the violation of the constraint, and thus reflect the corresponding energy supply security level.

BackgroundCurrent studies have revealed that acceptance and commitment therapy (ACT) can alleviate the adverse effects of cancer; however, its effectiveness on the psychological flexibility, fatigue, sleep disturbance, and quality of life of patients with cancer remains unclear.AimsThe aims of this study were to identify the effectiveness of ACT on psychological flexibility, fatigue, sleep disturbance, and quality of life of patients with cancer, and to explore moderators.MethodsPubMed, Embase, Web of Science, CENTRAL, PsycINFO, CINAHL, CNKI, VIP, and Wanfang electronic databases were searched from inception to September 29, 2022. The Cochrane Collaboration's risk‐of‐bias assessment tool II and the Grading of Recommendations Assessment, Development, and Evaluation approach were used to evaluate evidence certainty. The data were analyzed using R Studio. The study protocol was registered with PROSPERO (CRD42022361185).ResultsThe study included 19 relevant studies (1643 patients) published between 2012 and 2022. The pooled results showed that ACT significantly improved psychological flexibility (mean difference [MD] = −4.22, 95% CI [−7.86, −0.58], p = .02) and quality of life (Hedges' g = 0.94, 95% CI [0.59, 1.29], Z = 5.31, p < .01) but did not significantly improve fatigue (Hedges' g = −0.03, 95% CI [−0.24, 0.18], p = .75) or sleep disturbance (Hedges' g = −0.26, 95% CI [−0.82, 0.30], p = .37) in patients with cancer. Additional analyses revealed a 3‐month sustainable effect on psychological flexibility (MD = −4.36, 95% CI [−8.67, −0.05], p < .05), and moderation analysis showed that intervention duration (β = −1.39, p < .01) and age (β = 0.15, p = .04) moderated the effects of ACT on psychological flexibility and sleep disturbance, respectively.Linking Evidence to ActionAcceptance and commitment therapy demonstrates effectiveness for psychological flexibility and quality of life of patients with cancer, but there is a lack of evidence regarding its effects on fatigue and sleep disturbance. In clinical practice, ACT should be designed in more detail and rounded to achieve better results.
