Abstract
OBJECTIVE To analyze the density, distribution and insecticide resistance of Aedes albopictus in Ningbo City in 2021, so as to provide insights into formulation of dengue fever control strategies. METHODS Four administrative villages were randomly selected from each county (district) in Ningbo City from April to November, 2021, to investigate the indoor population density of Aedes larvae, and the Breteau index (BI) was calculated. The population density of adult mosquitoes was investigated in residential areas, parks/bamboo forests, waste tire stacking sites/waste stations/construction sites in each county (district). On June 2021, larvae of the natural strain A. albopictus were collected from epidemic sites of dengue fever in Ningbo City in 2018, and raised in laboratory. Then, larvae and female mosquitoes without blood feeding were selected for insecticide resistance bioassays, while insecticide-sensitive strains of A. albopictus served as controls. The resistance of A. albopictus larvae to deltamethrin, beta-cypermethrin, propoxur, temephos and dichlorvos using the impregnation method, and the medium lethal concentration (LC50) and resistance ratio (RR) were calculated. The resistance of adult A. albopictus to beta-cypermethrin, permethrin, deltamethrin, propoxur and malathion was determined using the tube bioassay, and the mosquito mortality was calculated. RESULTS A total of 10 072 small water containers from 9 935 households were investigated in Ningbo City in 2021, and there were 1 276 containers with Aedes larvae detected, with an average BI of 12.89. Totally 1 422 mosquito nets were allocated and 954 female A. albopictus were captured, with an average net trapping index of 1.34 mosquitoes/(net·hour). Both larval and adult A. albopictus mosquitoes were found from April to November, and the density of larval A. albopictus peaked in September (BI = 21.21), while the density of adult A. albopictus peaked in August, with a net trapping index of 2.38 mosquitoes/(net·hour). The LC50 values of delta-methrin, beta-cypermethrin, propoxur, temephos and dichlorvos were 0.017 4, 0.000 9, 0.364 1, 0.038 1 mg/L and 0.001 6 mg/L against larvae of natural strains of A. albopicchus, with RRs of 49.66, 25.53, 9.65, 2.24 and 6.06, and the mortality rates of adult mosquitoes were 66.00% (66/100), 69.39% (68/98), 25.00% (25/100), 98.97% (96/97) and 100.00% (98/98) 24 hours post-treatment with 0.08% beta-cypermethrin, 0.03% deltamethrin, 0.4% permethrin, 0.05% propoxur, and 0.5% malathion for 24 h, respectively. CONCLUSIONS A. albopictus is widely distributed in Ningbo City, with a high population density and presents high-level resistance to common pyrethroid insecticides. The population density and insecticide resistance of A. albopictus requires to be reinforced.

Abstract
SIGNIFICANCE We present a unique cause for zonular dehiscence, which provides a pathway for subsequent dislocation of an implanted phakic refractive lens (PRL) into the vitreous cavity. PURPOSE To determine the cause of zonular dehiscence and to avoid similar complications after PRL implantation in the future. CASE REPORT A 37-year-old highly myopic patient with refraction of -24.0 DS in both eyes received PRL implantation in both eyes. In the 14-month postoperative follow-up, it was found that the PRL dislocated into the vitreous cavity. The patient then underwent phacoemulsification and vitrectomy. The patient was treated successfully. No ocular complication was found. The visual acuity of the left eye was 20/40, two weeks after surgery. CONCLUSIONS We report a unique cause for zonular dehiscence, and the clarification of its detailed characteristics may contribute to prevention of such a complication in the future.

Abstract
Purpose Circulating exosomes regulate immune responses and induce immune tolerance in immune-mediated diseases. This study aimed to investigate the role of circulating small extracellular vesicles (sEVs) derived from patients with Vogt-Koyanagi-Harada (VKH) syndrome, in T-cell responses. Methods The sEVs were isolated from the plasma of healthy controls, patients with VKH, and other uveitis patients. The effects of autologous and allogeneic sEVs on the proliferation of circulating CD4+ T cells were evaluated. Microarray analysis of sEVs was performed to determine their differential miRNA expression profiles. The target genes of the candidate miRNA were predicted and verified. The role of both the candidate miRNA and target genes in T-cell proliferation was tested. Results Plasma-derived sEVs from patients with VKH inhibited the proliferation of autologous CD4+ T cells. Among all the miRNAs that might be associated with inflammatory activity, we found that miR-410-3p had the largest number of T-cell proliferation target genes. MiR-410-3p mimics inhibited the proliferation of Jurkat cells and CD4+ T cells. C-X-C motif chemokine ligand 5 (CXCL5) was confirmed to be a potential target gene of miR-410-3p, and siRNA-mediated CXCL5 knockdown inhibited cell proliferation. Conclusions Circulating sEVs exert an inhibitory effect on autologous CD4+ T cells mediated by miR-410-3p by targeting CXCL5, supporting the possibility of using autogenic sEVs to inhibit ocular inflammation.

Abstract
BACKGROUND Alzheimer's disease (AD) is a type of disease frequently occurs in the elderly population. Diagnosis and treatment methods for this disease are still lacking, and more research is required. In addition, little is known about the function of the circular RNAs (circRNAs) in AD. METHODS In this research, RNA expression data of AD from the Gene Expression Omnibus (GEO) database were downloaded. The expression levels of circRNAs in cerebrospinal fluid samples of healthy participants and AD patients were measured by reverse transcription‑quantitative PCR (RT-qPCR). The diagnosed value of differential expressed circRNAs was analyzed with the Receiver operating characteristic curve (ROC). Pathways related to circ_0001535 were found using gene set enrichment analysis (GSEA) and Metascape. The direct interactions between circ_0001535 and E2F transcription factor 1 (E2F1) or E2F1 and dihydrofolate reductase (DHFR) were verified using Chromatin immunoprecipitation (ChIP) and RNA Binding Protein Immunoprecipitation (RIP) assays. Cell Counting Kit-8 (CCK8) and flow cytometry were used to identify the function of circ_0001535/E2F1/DHFR axis on the proliferation and apoptosis of AD cells. RESULTS In total, 12 circRNAs have been linked to AD diagnosis. The expression levels of 7 circRNAs differed between AD patients and control groups. Circ_0001535 had the most diagnose value among these circRNAs. Hence, circ_0001535 was regarded as a key circRNA in the present study. E2F1/DHFR axis was predicted to be regulated by circ_0001535. In addition, IP assays experiment results showed that E2F1 could bind to the promoter region of DHFR and be regulated by circ_0001535. In vitro results showed that circ_0001535 overexpression could promote DHFR expression, while E2F1 knock down could inhibit DHFR expression in SH-SY5Y cells. Finally, rescue experiments suggested that circ_0001535 could reduce Aβ25-35-induced SH-SY5Y cell proliferation and facilitate apoptosis through E2F1/DHFR axis. CONCLUSIONS Our research in AD circRNA can offer important information regarding the role of specific circRNAs in the AD environment and point to specific future areas of therapeutic intervention in AD.

Abstract
Accumulating evidence now demonstrated that circular RNAs (circRNAs) are closely related to the pathogenesis of lung adenocarcinoma (LUAD). Through GEO2R online analysis, we screened hsa_circ_0000009 (circ_0000009) from the GEO database (GSE158695), and its expression in LUAD cancer tissues and cell lines was detected by RT-qPCR. The looping structure of circ_0000009 was tested by RNase R and actinomycin D experiments. The changes of proliferation were tested by CCK-8 or EdU assay. And the changes of apoptosis in A549 and H1299 cells were measured via flow cytometry. The A549 BALB/c tumor model was established to evaluate the influence of circ_0000009 on LUAD cell growth in vivo. In addition, experiments connected with ceRNA direction (mainly including bioinformatics prediction and luciferase reporter assay) and RNA Binding Protein (RBP) direction (mainly including RNA pull-down assay, RIP assay and mRNA stability assay) were further developed to reveal the regulatory mechanism of circ_0000009. The gene and protein levels in this project were assessed by RT-qPCR and western blotting analysis, respectively. The data manifested that circ_0000009 was in low expression in LUAD. The in vitro and in vivo experiments threw light on that overexpression of circ_0000009 dramatically suppressing LUAD tumorigenesis. Mechanistically, circ_0000009 promoted the expression of PDZD2 by sponging miR-154-3p. Furthermore, circ_0000009 stabilized PDZD2 by recruiting IGF2BP2. This study illustrated the mechanism that overexpressing of circ_0000009 suppressed LUAD progression by upregulating PDZD2 expression, providing an original treatment direction for LUAD.

Eur J Pediatr 2023:10.1007/s00431-023-04965-7.

Abstract
This study investigated the characteristics of refractive status, visual acuity, and retinal morphology in children with a history of receiving intravitreal ranibizumab for retinopathy of prematurity (ROP). Children 4-6 years of age were enrolled and divided into the following four groups: group 1, children with a history of ROP who had been treated with intravitreal ranibizumab; group 2, children with a history of ROP who had not received any treatment; group 3, premature children without ROP; and group 4, full-term children. Refractive status, peripapillary retinal nerve fiber layer (RNFL), and macular thickness were measured. A total of 204 children were enrolled. In group 1, myopic shift was not noted, but poorer best corrected visual acuity (BCVA) and shorter axial length were observed. Significantly lower peripapillary RNFL thickness in the average total and superior quadrant, higher central subfield thickness, lower parafoveal retinal thickness in average total, superior, and nasal and temporal quadrants were observed in group 1 than in the other groups. The poor BCVA in patients with ROP was correlated with the lower RNFL thickness in the superior quadrant. Conclusion: Children with a history of type 1 ROP treated with ranibizumab did not show a myopic shift but did show abnormal retinal morphology and the poorest BCVA among all groups. We suggest that pediatric ophthalmologists should always pay attention to visual development in patients with ROP with a history of intravitreal ranibizumab. What is Known: • Anti-VEGF is efficiently and widely used in the treatment of type 1 retinopathy of prematurity (ROP), and different anti-VEGF agents are associated with different prevalence of myopia. • Patients with ROP who receive treatment such as laser therapy or cryotherapy have abnormal macular development and retinal nerve fiber layer (RNFL) thickness. What is New: • Children with a history of ROP treated with intravitreal ranibizumab did not show a myopic shift but did show poor BCVA at 4-6 years of age. • Abnormal macular morphology and lower peripapillary RNFL thickness were found in these children.

Abstract
Pyrite FeS2 now emerges as a promising anode for potassium-ion batteries (PIBs) due to its low cost and high theoretical capacity. However, the significant volume expansion, low electrical conductivity, and the ambiguous mechanism related to potassium storage severely hinder its development for PIBs anodes. Herein, FeS2 nanostructures are skillfully dispersed on the graphene surface layer by layer (FeS2@C-rGO) to form a sandwich structure by using Fe-based metal organic framework (Fe-MOF) as precursors. The unique structural design can improve the transfer kinetics of K+ and effectively buffer the volume expansion during cycling, thereby enhancing the potassium storage performance. As a result, the FeS2@C-rGO delivers a high capacity of 550 mAh/g at a current density of 0.1 A/g. At a high rate of 2 A/g, the capacity can maintain 171 mAh/g even after 500 cycles. Moreover, the electrochemical reaction mechanism and potassium storage behavior are revealed by in-situ X-ray diffractionand density functional theory calculations. This work not only provides a novel insight into the structural design of electrode materials for high-performance PIBs, but also proposes a valuable understanding of the potassium storage mechanism of the FeS2-based anode.

Abstract
Selective electro-oxidation of aliphatic alcohols into value-added carboxylates at lower potentials than that of the oxygen evolution reaction (OER) is an environmentally and economically desirable anode reaction for clean energy storage and conversion technologies. However, it is challenging to achieve both high selectivity and high activity of the catalysts for the electro-oxidation of alcohols, such as the methanol oxidation reaction (MOR). Herein, a monolithic CuS@CuO/copper-foam electrode for the MOR with superior catalytic activity and almost 100% selectivity for formate is reported. In the core-shell CuS@CuO nanosheet arrays, the surface CuO directly catalyzes MOR, while the subsurface sulfide not only serves as an inhibitor to attenuate the oxidative power of the surface CuO to achieve selective oxidation of methanol to formate and prevent over-oxidation of formate to CO2 but also serves as an activator to form more surface O defects as active sites and enhances the methanol adsorption and charge transfer to achieve superior catalytic activity. CuS@CuO/copper-foam electrodes can be prepared on a large scale by electro-oxidation of copper-foam at ambient conditions and can be readily utilized in clean energy technologies.

Abstract
In this investigation, non-spontaneous combustion coal gangue was activated by two methods: (1) low-temperature calcination and (2) calcium addition. Differences in the activity of the activated coal gangue were studied at various calcination temperatures and amounts of calcium addition. Meanwhile, the cementation activity of the activated coal gangue was evaluated according to the activity effect analysis. Furthermore, the influences of the activated coal gangue on the cementation activity of cement were investigated. The results indicated that the activities of the activated coal gangue increased at a temperature between 500 °C and 700 °C. The calcium addition method can also increase the activity of coal gangue, with the effect being better when the gangue is mixed with slag. The addition of calcium and the calcination of coal gangue can promote the production of active minerals such as metakaolin, which is the main reason for the increased cementation activity.

Abstract
The effects of an electron shuttle (dissolved black carbon (DBC) derived from biochar) on the microbial reduction of ferrihydrite and subsequent imidacloprid (IMI) degradation were studied. The results showed that DBC addition enhanced the microbial reduction of Fe(III) in ferrihydrite and increased the quantity of Fe(II) released into the liquid phase. The electron transfer capacity of DBC was significantly influenced by the content of redox-active oxygen-containing functional groups (e.g., quinone, hydroquinone, and polyphenol groups), which was dependent on the pyrolysis temperature. The electrochemical characteristics of DBC resulted in enhanced electron transfer, which promoted Fe(III) reduction and mediated the microbial transformation of ferrihydrite. The microbial transformation of ferrihydrite resulted in the formation of secondary minerals such as siderite and vivianite. The IMI degradation efficiency was related to the Fe(III) reduction rate and the pyrolysis temperature used in DBC production, and the degradation pathways were nitrate reduction and imino hydrolysis induced by the Fe(II) generated from the reduction of Fe(III) in ferrihydrite. The results obtained in this study provide new data for understanding the multifunctional roles of biochar-derived DBC in the redox and transformation processes of iron minerals induced by iron-reducing bacteria, the related biogeochemical cycles of iron and the fate of pollutants.

Abstract
BACKGROUND To investigate the prevalence and predictors of retinal breaks reopening after vitrectomy with air tamponade in rhegmatogenous retinal detachment (RRD). METHODS A retrospective cohort study was conducted in Shanghai General Hospital. Chart review was performed among 1715 patients with primary RRD who received pars plana vitrectomy (PPV) with air tamponade as initial management. Patients were followed up for recurrence. The clinical features of the eyes with retinal breaks reopening were recorded. Logistic regression was constructed to investigate the predictors for breaks reopening. RESULTS A total of 137 (7.99%) patients had recurrent retinal detachment after PPV with air tamponade. The causes of surgery failure included new or missed retinal breaks (48.9%), reopening of original tears (43.8%) and proliferative vitreoretinopathy (7.3%). The median time to recurrence for the patients with breaks reopening was 18.0 days. Multivariate logistic regression indicated that the presence of retinal break(s) ≥ 1.5 disc diameters (DD) (odds ratio [OR]: 2.68, 95% confidence interval [CI]: 11.04-6.92, P = 0.041), and shorter period for restricted activities (OR: 0.94, 95% CI: 0.89-0.99, P = 0.020) were the independent predictors for breaks reopening. CONCLUSIONS Breaks reopening is an important cause for retinal redetachment after PPV with air tamponade in primary RRD. The first 2-4 weeks after surgery is the "risk period" for breaks reopening. Special attention should be paid for patients with retinal break(s) ≥ 1.5 DD. A prolonged period for restricted activities is recommended.

Abstract
BACKGROUND Transient receptor potential channel 6 (TRPC6) is reported to be involved in the pathogenesis of diabetic complications, but its role in diabetic retinopathy (DR) remains unknown. The aim of our study was to determine the role and mechanism of TRPC6 in DR. METHODS High glucose was used to construct a DR cell model using rat retinal Müller cells (rMC-1). Intracellular Ca2+, reactive oxygen species (ROS) and cell pyroptosis were evaluated by flow cytometry. Protein levels of NLRP3, pro-caspase-1, active caspase-1, gasdermin D (GSDMD), GSDMD-N, TRPC6 and H3K27ac were detected by Western blot. mRNA levels of EP300 and TRPC6 were analyzed by reverse transcriptase-polymerase chain reaction (RT-PCR). Levels of IL-1β and IL-18 were estimated by enzyme linked immunosorbent assay (ELISA). The interaction between EP300 and TRPC6 was validated by a chromatin immunoprecipitation assay. RESULTS The knockdown of TRPC6 reduced inflammation and cell pyroptosis in HG induced rMC-1 cells, whereas overexpression of TRPC6 had the opposite effects. The inhibition of ROS and NLRP3 reversed TRPC6-mediated cell pyroptosis in the DR cell model. In addition, EP300 increased the expression of H3K27ac and TRPC6 to promote cell pyroptosis, which was suppressed by the knockdown of TRPC6. CONCLUSIONS Our study revealed a novel EP300/H3K27ac/TRPC6 signaling pathway that may contribute to HG induced Müller cell pyroptosis. TRPC6 played a novel role in Müller cell pyroptosis triggered by HG, and may be a potential target for DR treatment in the future.

Abstract
PURPOSE To evaluate the feasibility and usefulness of cine magnetic resonance urography (cine MRU) as a novel postoperative examination after upper urinary tract reconstruction surgery. METHODS Ninety-six patients underwent cine MRU for postoperative evaluation between August 2015 and August 2020. The morphological observations included regular peristalsis, anastomosis, urine flow signals, and reflux. The quantitative evaluations included luminal diameter, peristaltic amplitude, contraction ratio, peristaltic waves, and ureteric jets. The surgical outcomes were classified as success, gray area, or failure by combining the results of cine MRU, symptoms, and the degree of hydronephrosis. RESULTS There was no obvious stenosis of the anastomosis in 83 patients (86.46%). Regular peristalsis of the ureter and signals of urination was observed in 85 (88.54%) and 84 patients (87.50%), respectively. In addition, three patients (3.13%) showed urine reflux. The patients in both the success group and the gray area group showed significantly different creatinine levels (success 86.2 ± 22.3 μmol/L vs. failure 110.7 ± 8.2 μmol/L, P = 0.016; gray area 81.0 ± 20.0 μmol/L vs. failure 110.7 ± 8.2 μmol/L, P = 0.009) and estimated glomerular filtration rate (success: 88.5 ± 23.1 mL/min·1.73 m2, failure: 61.6 ± 14.1 mL/min·1.73 m2, P = 0.014; gray area: 94.7 ± 24.6 mL/min·1.73 m2, failure: 61.6 ± 14.1 mL/min·1.73 m2, P = 0.007) compared to those in the failure group. The ipsilateral split renal function was 33.6 ± 15.0, 24.5 ± 13.4, and 20.1 ± 0.4 mL/min in the success, gray area, and failure groups, respectively (P = 0.354). CONCLUSION Cine MRU demonstrates the morphology and function of the reconstructed upper urinary tract. The results of cine MRU can be used to evaluate the surgical effect, providing guidance for further treatment.

Abstract
Oxysophoridine (OSR) is an alkaloid extracted from Sophora alopecuroides L. and exerts beneficial effects in cerebral ischemia/reperfusion (I/R) injury. However, the molecular mechanism underlying the regulatory effects of OSR in cerebral I/R injury remains unclear. In the present study, a cerebral I/R injury rat model was established by occlusion of the right middle cerebral artery. Hematoxylin and eosin and triphenyltetrazolium chloride staining were performed to assess histopathological changes and the extent of cerebral injury to the brain. A Cell Counting Kit‑8 and TUNEL assay and western blotting were performed to assess cell viability and apoptosis. Ferroptosis and oxidative stress were evaluated based on ATP and Fe2+ levels and DCFH‑DA staining. The protein expression levels of inflammatory factors were assessed using ELISA. The protein expression levels of members of the toll‑like receptor (TLR)4/p38MAPK signaling pathway were evaluated using immunofluorescence staining and western blotting. The results demonstrated that OSR decreased brain injury and neuronal apoptosis in the hippocampus in I/R‑induced rats. OSR inhibited reactive oxygen species (ROS) production, decreased levels of ATP, Fe2+ and acyl‑CoA synthetase long‑chain family member 4 (ACSL4) and transferrin 1 protein and increased the protein expression levels of ferritin 1 and glutathione peroxidase 4. Furthermore, OSR blocked TLR4/p38MAPK signaling in brain tissue in the I/R‑induced rat. In vitro experiments demonstrated that TLR4 overexpression induced generation of ROS, ATP and Fe2+, which promoted the expression of ferroptosis‑associated proteins in hippocampal HT22 neuronal cells. The ferroptosis inducer erastin decreased the effects of OSR on oxygen‑glucose deprivation/reoxygenation (OGD/R)‑induced cell viability, oxidative stress and inflammatory response. Together, the results demonstrated that OSR alleviated cerebral I/R injury via inhibition of TLR4/p38MAPK‑mediated ferroptosis.

Abstract
OBJECTIVE This study investigated the feasibility and accuracy of fetal intelligent navigation echocardiography (FINE) for the prenatal diagnosis of congenital heart disease (CHD) by inexperienced and experienced operators. METHOD In this prospective study, all volume data sets from 120 fetuses with a broad spectrum of CHD were acquired using spatiotemporal image correlation technology. The prenatal diagnostic procedures were performed by two operators with different experience (beginner: 1 year and expert: 15 years) using FINE and traditional fetal echocardiography. Data were analyzed on the time of examination and acquisition of results. RESULTS Diagnoses made by FINE and traditional echocardiography were completely consistent with the final diagnosis of CHD in 98 (81.66%) versus 20 (16.66%) (P < 0.001) beginners and 87.50% (n = 105) versus 101 (84.16%) experts, respectively. On the contrary, there was significant difference using traditional echocardiography (16.66% versus 84.16%, P < 0.001) by two examiners. Furthermore, the examination time decreased when using FINE compared with using traditional echocardiography (beginner operators: 4.54 ± 1.03 min versus 20.58 ± 3.36 min, P < 0.001; expert operators: 3.89 ± 0.96 min versus 12.73 ± 1.62 min, P < 0.001). CONCLUSION Based on our results, a prenatal diagnosis of CHD can be made with high feasibility and accuracy using FINE compared with traditional fetal echocardiography for beginner operators.

Abstract
Body mass index (BMI) and gut microbiota show significant interaction, but most studies on the relationship between BMI and gut microbiota have been done in Western countries. Relationships that are also identified in other cultural backgrounds are likely to have functional importance. Hence here we explore gut microbiota in adults living in Xining city (China P.R.) and relate results to subject BMI. Analysis of bacterial 16s rRNA gene was performed on faecal samples from participants with normal-weight (n=24), overweight (n=24), obesity (n=11) and type 2 diabetes (T2D) (n=8). The results show that unweighted but not weighted Unifrac distance was significantly different when gut microbiota composition was compared between the groups. Importantly, the genus Streptococcus was remarkably decreased in both obese subjects and subjects suffering from T2D, as compared to normal-weight subjects. Accordingly, strong association was identified between the genus Streptococcus and BMI and especially Streptococcus salivarius subsp. thermophiles was a major contributor in this respect. As previous studies have shown that Streptococcus salivarius subsp. thermophiles is also negatively associated with obesity in Western cohorts, our results suggest that this species is a potential probiotic for the prevention of obesity and related disorders.
