Objective:To observe and analyze the correlations between aqueous humor cytokine concentrations and disorganization of retinal inner layers (DRIL), as well as postoperative visual acuity, in patients with idiopathic epiretinal membrane (iERM).Methods:A prospective clinical study. From November 2022 to October 2024, 40 eyes of 40 patients diagnosed with iERM at Ophthalmology Center of Zhejiang Provincial People's Hospital (Affiliated People's Hospital) underwent cataract surgery alone or combined with pars plana vitrectomy (iERM group) were enrolled; 19 eyes of 19 patients undergoing cataract surgery alone during the same period served as the control group. All eyes underwent best-corrected visual acuity (BCVA) testing and swept-source optical coherence tomography (SS-OCT). BCVA was assessed using a logarithmic visual acuity chart and converted to the logarithm of the minimum angle of resolution (logMAR) for statistical analysis. Central macular thickness (CMT) was measured using SS-OCT. The iERM group was further subdivided into DRIL-positive and DRIL-negative subgroups (21 eyes and 19 eyes, respectively), based on the presence or absence of DRIL. Aqueous humor samples were collected preoperatively from eyes in both the iERM and control groups. Concentrations of transforming growth factor (TGF)-β1, TGF-β2, TGF-β3, platelet-derived growth factor (PDGF)-AB, hepatocyte growth factor, fibroblast growth factor, vascular endothelial growth factor-A (VEGF-A), placental growth factor (PLGF), glial cell line-derived neurotrophic factor (GDNF), intercellular adhesion molecule-1 (ICAM-1), angiopoietin (Ang)-1, Ang-2, tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) were measured. Follow-up examinations using the same equipment and methods were performed at 1 month postoperatively. Aqueous cytokine levels were compared between the iERM group, control group, DRIL-positive subgroup, and DRIL-negative subgroup. Correlations between aqueous cytokine levels in the iERM group and BCVA or CMT were also analyzed. Intergroup comparisons utilized the Mann-Whitney U test; correlations between variables were assessed using Spearman's rank correlation analysis. Results:Compared to the control group, the iERM group exhibited significantly higher aqueous concentrations of TGF-β1, TGF-β3, PDGF-AB, PLGF, GDNF, ICAM-1, Ang-1, and TNF-α ( P<0.05). Compared to the DRIL-negative subgroup, the DRIL-positive subgroup showed significantly elevated aqueous concentrations of TGF-β3, PDGF-AB, PLGF, GDNF, ICAM-1, Ang-1, Ang-2, TNF-α, and IL-6 ( P<0.05). Significant differences were observed in logMAR BCVA ( P=0.028) and CMT ( P<0.001) within the iERM group between preoperative and 1-month postoperative measurements. LogMAR BCVA differed significantly between the DRIL-positive and DRIL-negative subgroups ( P=0.048). Correlation analysis revealed that baseline aqueous levels of VEGF-A and IL-6 in eyes with DRIL were positively correlated with postoperative BCVA ( r=0.324, 0.452; P=0.042, 0.003). No significant correlation was found between CMT and any cytokine ( P>0.05). Conclusions:Aqueous humor cytokines are closely associated with DRIL in iERM patients. IL-6 and VEGF-A may serve as potential predictive biomarkers for early postoperative visual recovery.

Objective:To explore the effect and mechanism of naringenin (NAR) on glucose and lipid metabolism and oxidative stress in rats with gestational diabetes mellitus (GDM) .Methods:10 normal pregnant rats were selected as the control group, and the GDM model was prepared. One-time tail iv streptozotocin (STZ, 35 mg/kg) was used to construct GDM model. The 50 rats successfully modeled were divided into model group, metformin group (Met group, 20 mg/kg), low NAR (NAR-L, 50 mg/kg), high (NAR-H, 100 mg/kg) dose groups and NAR+EX527 group (NAR 100 mg/kg+EX527 10 mg/kg), 10 rats per group. Rats in Met group and NAR low-dose and high-dose groups were given corresponding doses of drugs ig. Rats in NAR+EX527 group were given NAR ig and EX527 ip at the same time, once a day, for 28 consecutive days. The levels of fasting blood glucose (FBG) and fasting serum insulin (FINS) in rats were detected, and the homeostasis model assessment for insulin resistance (HOMA-IR) was calculated; the levels of serum triglycerides (TG), cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) were detected; the level of malondialdehyde (MDA) in pancreatic tissue and the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) were detected; the tissue lesions of pancreas and placenta were observed with HE staining; the expression of pancreatic tissue AMP-activated protein kinase (AMPK), p-AMPK, silent information regulator 1 (SIRT1), peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1 α) proteins was detected with Western blotting method. Results:Compared with control, the FBG, FINS, HOMA-IR, serum TC, TG, LDL-C levels, and pancreatic tissue MDA level in the model group were significantly increased, the SOD and GSH-Px activities, pancreatic tissue p-AMPK/AMPK ratio and SIRT1 and PGC-1 α expression levels were significantly reduced ( P<0.05), and the placenta and pancreas tissues showed obvious pathological damage; Compared with the model group, the FBG, FINS, HOMA-IR, serum TC, TG, LDL-C levels, and pancreatic tissue MDA level in the Met group and the NAR-L and NAR-H groups were significantly reduced, the SOD and GSH-Px activities, pancreatic tissue p-AMPK/AMPK ratio and SIRT1 and PGC-1 α expression levels were significantly increased ( P<0.05), the placenta and pancreas tissues damage reduced; and on the basis of NAR intervention, the use of SIRT1 inhibitor EX527 could significantly reverse the protective effect of NAR on GDM rats. Conclusion:NAR may improve glucose and lipid metabolism disorder and oxidative stress response in GDM rats by activatin SIRT1/PGC-1 α pathway.

Objective:To observe the changes of peripapillary vessel density and retinal nerve fiber layer parameters (RNFL) in diabetic mellitus (DM) patients with early diabetic retinopathy (DR).Methods:A retrospective clinical study. From January to December 2018, twenty-eight DM patients (47 eyes, DM group) and 20 normal subjects (40 eyes, control group) in Eye Hospital of Wenzhou Medical University at Hangzhou were included in the study. There was no significant difference between the two groups in age ( t=-1.397, P=0.169) and sex composition ratio ( χ2=0.039, P=0.843). The optic nerve head was scanned by OCT angiography (OCTA) with HD 4.5 mm ×4.5 mm imaging scanning mode for all subjects. The peripapillary radial peripapillary capillaries vessel density (ppVD) and peripapillary retinal nerve fiber layer (pRNFL) thickness were measured. The changes of ppVD and pRNFL thickness between the two groups were observed. Pearson correlation analysis was used to analyze the correlation between ppVD and pRNFL in each quadrant. Results:Compared with the control group, the mean ppVD and superior-hemi part, inferior-hemi part, superior, nasal, inferior and temporal quadrant ppVDs of DM group were all significantly lower than those of control group ( t=5.107, 4.360, 3.713, 4.007, 2.806, 4.046, 2.214; P<0.05). The mean and all quadrants pRNFL thickness were lower in eyes of DM group compared with the control, and the superior and inferior quadrant pRNFL thickness were statistically significant ( t=2.117, 2.349; P<0.05), while the mean pRNFL and superior-hemi, inferior-hemi part, nasal and temporal quadrant were not statistically significant ( t=1.867, 1.717, 1.869, 0.720, 0.303; P>0.05). Pearson correlation analysis showed that the significant high-positive correlation was found between ppVD and pRNFL thickness in the nasal quadrant ( r=0.734, P<0.001). Conclusion:In early DR patients, ppVD decreased and pRNFL thinned.

Malignant tumor has become an urgent threat to global public healthcare. Because of the heterogeneity of tumor, single therapy presents great limitations while synergistic therapy is arousing much attention, which shows desperate need of intelligent carrier for co-delivery. A core‒shell dual metal-organic frameworks (MOFs) system was delicately designed in this study, which not only possessed the unique properties of both materials, but also provided two individual specific functional zones for co-drug delivery. Photosensitizer indocyanine green (ICG) and chemotherapeutic agent doxorubicin (DOX) were stepwisely encapsulated into the nanopores of MIL-88 core and ZIF-8 shell to construct a synergistic photothermal/photodynamic/chemotherapy nanoplatform. Except for efficient drug delivery, the MIL-88 could be functioned as a nanomotor to convert the excessive hydrogen peroxide at tumor microenvironment into adequate oxygen for photodynamic therapy. The DOX release from MIL-88-ICG@ZIF-8-DOX nanoparticles was triggered at tumor acidic microenvironment and further accelerated by near-infrared (NIR) light irradiation. The

Pulmonary drug delivery has attracted increasing attention in biomedicine, and porous particles can effectively enhance the aerosolization performance and bioavailability of drugs. However, the existing methods for preparing porous particles using porogens have several drawbacks, such as the inhomogeneous and uncontrollable pores, drug leakage, and high risk of fragmentation. In this study, a series of cyclodextrin-based metal-organic framework (CD-MOF) particles containing homogenous nanopores were delicately engineered without porogens. Compared with commercial inhalation carrier, CD-MOF showed excellent aerosolization performance because of the homogenous nanoporous structure. The great biocompatibility of CD-MOF in pulmonary delivery was also confirmed by a series of experiments, including cytotoxicity assay, hemolysis ratio test, lung function evaluation,

Objective:
To understand the situation of neglect and behavior problems of children aged 3-6 years in rural areas of Urumqi, Xinjiang, and to provide basis and reference for the prevention and treatment of child neglect.
Methods:
Stratified random cluster sampling was performed to select 1 326 children aged 3-6 years from 6 kindergartens in rural Urumqi. The “Chinese Rural Child Aged 3-6 Years Neglect Evaluation Norm” and “Conners Parent Symptom Questionnaire” were used.
Results:
The total neglect rate of rural children was 51.89%, and the rate of behavioral problems was 23.37%. Each dimensional score of neglect among children with behavioral problems was higher than those without behavior preblems, and the difference was statistically significant (t=2.77,4.05,2.95,2.44,3.01,2.71,P<0.05). Emotional neglect was correlated with all factors in behavioral preblems, except phychosomation fact (r=0.18,0.80,0.15,0.14,0.19,P<0.05). Neglect in educational was correlated with all factors in behavioral factors except anxiety and hyperactivity (r=0.06,0.05,0.62,0.08,P<0.05).
Conclusion
Neglect of children aged 3-6 years in rural areas of Urumqi is more prominent and behavioral problems are more common, which should be paid more attention by relevant departments and parents.

Objective:To investigate the correlation of the blood concentration of tacrolimus ( Tac) and serum cystatin C ( SCysC) and serum creatinine (Scr) in the patients with renal transplantation. Methods:Totally 84 cases of renal transplantation patients (67 male/17 female) treated with Tac were involved. The blood concentration of Tac, SCysC and Scr were monitored after the operation. Data results were categorized according to the postoperative time and the blood concentration. The correlations of Tac blood concentra-tion,SCysC and Scr were analyzed and compared by using Pearson correlation analysis. Results: The blood concentration of Tac was not significantly associated with SCysC and Scr in different postoperative time groups and different drug concentration groups ( P >0. 05). As the extension of time,the blood concentration of Tac showed a gradual declining trend, while SCysC and Scr levels de-creased first, and then increased gradually after two years of the operation. Conclusion:The blood concentration of Tac has no effect on the function evaluation of transplanted kidney by the biochemical indicators such as SCysC and Scr.
