The patient population was divided into two groups: the Ommaya-used group, comprising patients in whom the Ommaya drainage system was activated post-surgery, and the Ommaya-unused group, comprising patients in whom the system was not activated. The study analyzed clinical, imaging, and outcome data of the patient population.Results: A total of 123 patients with IVH were included: 75 patients in the Ommaya-used group and 48 patients in the Ommaya-unused group. The patients in the Ommaya-used group showed a lower 3-month GOS than those in the Ommaya-unused group (p< 0.0001). The modified Graeb scale (mGS) in the Ommaya-unused group was significantly lower than that in the Ommaya-used group before the operation (p< 0.01) but not after surgery (p> 0.05). The GCS in the Ommaya-unused group was significantly lower than that in the other group, and there was a close correlation between the GCS and 3-month GOS (p< 0.0001). The GCS score showed significance in predicting the use of Ommaya (p< 0.001).Conclusion: The study demonstrated that combining EVD and Ommaya drainage was a safe and feasible treatment for IVH. Additionally, preoperative GCS was found to predict the use of Ommaya drainage in subsequent treatment, providing valuable information for pre-surgery decision-making.Keywords: intraventricular hemorrhage, Ommaya, external ventricular drainage

The subjects were divided into branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO) according to the involved vessel, subsequently the subjects received intravitreal conbercept treatment. The BCVA and fundus microstructure were measured to identify predictors of effective outcomes.Results: BCVA, central retinal thickness (CRT), fovea avascular zone (FAZ), and foveal vascular density (FVD) in superficial capillary plexus (SCP) were significantly changed from baseline to 6-month follow-up in both CRVO and BRVO. In the BRVO group, age and baseline BCVA were correlated with changes of BCVA, while the baseline CRT, FVD in the DCP, and parafovea vascular density (PFVD) in DCP were associated with changes of CRT (P< 0.05). In the CRVO group, the baseline BCVA was correlated with changes of BCVA, while age, gender, baseline CRT, FVD in DCP, and PFVD in DCP were associated with changes of CRT (P< 0.05). There were no serious adverse events (SAEs) related to the drug or the injection procedure.Conclusion: Intravitreal injections of conbercept can improve BCVA and CRT and change the FVD in SCP effectively both in BRVO and CRVO groups. In addition, the baseline FVD and PFVD in the DCP were related to the change of CRT after intravitreal conbercept treatment.Keywords: conbercept, retinal vein occlusion, macular edema, microvascular structure, best-corrected visual acuity

Face-to-face interviews were conducted to collect information on socio-demographics, preferences for WeChat-based and hospital-based family intervention, social support, and coping.Results: Over 72.16% of participants endorsed hospital-based family intervention, while 50.11% endorsed WeChat-based family intervention. Endorsement of WeChat-based family intervention was associated with younger age (OR=0.42, 95% CI: 0.22, 0.79), WeChat use (OR=12.90, 95% CI: 7.48, 22.23), and higher social support (OR=1.03, 95% CI: 1.01, 1.04). Endorsement of hospital-based family intervention was associated with lower education (OR=0.19– 0.37, 95% CI: 0.07, 0.66) and WeChat use (OR=3.27, 95% CI: 1.91, 5.59).Conclusion: The studies showed a higher endorsement rate for hospital-based family intervention than WeChat-based family intervention and provide implications for developing targeted family intervention programs based on participants’ own unique characteristics.Keywords: preference, WeChat, caregiving, schizophrenia

Depression was assessed using the Centre for Epidemiological Studies Depression Scale (CES-D). Vision-related quality of life was evaluated using the Visual Function Questionnaire-25 (VFQ-25). Social support was captured with the Social Support Rating Scale (SSRS). Generalized linear models were used to estimate the individual and joint association of VFQ-25 composite score (VFQCS) and SSRS score (SSRSS) with depression.Results: A total of 1618 subjects (60.9% female) aged 61.69 ± 8.72 years in an urban district of Jiangjun Street, Fushun City, Liaoning province, Northeast China from July 2012 to May 2013 were recruited, of which, 23.36% (95% CI: 21.30– 25.42%) were identified with depression. Every 14.1 increase in VFQ-25 composite score decreased the risk of depression by half (OR = 0.5; 95% CI: 0.4– 0.6); with the elevation of 10.0 SSRS score the risk of depression decreased by 40% (OR = 0.6; 95% CI: 0.5– 0.7). Patients with the VFQCS less than 91.3 and SSRSS less than 38.0 had 5.9 times more risk of depression (OR = 5.9; 95% CI: 3.6– 9.7). Age (over 60 years) (OR = 0.6; 95% CI: 0.4– 0.9) and medical history of cardiovascular disease (OR = 1.7; 95% CI: 1.1– 2.5) were independently correlated with depression symptom.Conclusion: The prevalence of depression is high among patients with T2DM in urban district in northeast China. Vision-related quality of life and social support scores are significantly associated with depression. Measures should be taken to screen depressive symptoms in patients with type 2 diabetes patients. These patients need to be intervened with appropriate and effective treatment as early as possible. Meanwhile, behavioral health specialists should guide the patient to get and use social support sources effectively.Keywords: diabetic retinopathy, depression, quality of vision, Visual Function Questionnaire-25, Social Support Rating Scale

The aim of this study was to reveal key genes for prognosis and establish prognostic gene signatures based on genes encoded by chr1p/19q.Materials and methods: The data was downloaded from The Cancer Genome Atlas (TCGA), Chinese Glioma Genome Atlas (CGGA) and Gene Expression Omnibus (GEO). Differentially expressed genes (DEGs) between lower grade glioma tissue and normal brain were identified. The univariate COX regression, robust likelihood-base survival analysis (rbsurv) and multivariate COX regression analysis were used to establish the 4-gene-signature based on the DEGs. The receiver operating characteristic (ROC) curve and the Kaplan-Mere curve were used to verify the prediction accuracy of the signature. Gene Set Enrichment Analysis (GSEA) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were also performed to explore the reasons for good prognosis in patients with chr1p/19q deletion.Results: A total of 1346 DEGs were identified between lower grade glioma samples and normal brain samples in GSE16011, including 56 up-regulated mRNAs located on chr1p and 20 up-regulated mRNAs located on chr19q. We established a 4-gene-signature that was significantly associated with survival based on the 76 gene. The AUC of the 4-gene-signature for 5-year OS in TCGA and CGGA was 0.837 and 0.876, respectively, which was superior compared to other parameters such as chr1p/19q co-deletion, IDH mutant, WHO grade and histology type, especially in chr1p/19q non-co-deletion patients. GSEA and KEGG analysis suggested that the prolongation of chr1p/19q in patients could be associated with cell cycle and DNA mismatch repairing.Conclusions: We established a robust 4-gene-signature based on the chr1p/19q and we explored the potential function of these newly identified survival-associated genes by bioinformatics analysis. The 4-gene from the signature are promising molecular targets to be used in the future.Keywords: lower grade glioma, prognostic signature, 1p/19q co-deletion, rbsurv

Reduced melanogenesis may lead to depigmentation conditions such as vitiligo. Psoralen, a furocoumarin derivative, is closely associated with melanogenesis, and its derivative 8-methoxypsoralen is used in psoralen and ultraviolet A therapy for pigmentation disorders. In a previous study, we synthesized a new series of amine derivatives of furocoumarin, of which 5-(morpholinomethyl)-3-phenyl-7H-furo[3,2-g]chromen-7-one (encoded as D206008) showed a remarkable melanogenic effect in B16 murine cells.Methods: In this study, we examined the effects of D206008 on the melanogenesis-related pathways in B16 cells. D206008 increased melanin production and tyrosinase (TYR) activity, as well as the mRNA and protein expression levels of the melanogenic enzymes TYR, TRP-1 and TRP-2, and the melanogenesis-related transcription factor microphthalmia-associated transcription factor (MITF) in a dose-dependent (0–100 µM) and time-dependent (0–48 hours) manner.Results: Mechanistically, D206008 inhibited β-catenin degradation by enhancing the phosphorylation of Akt and glycogen synthase kinase-3β (GSK-3β), which increased the accumulation of β-catenin in the cytoplasm. Nuclear translocation of β-catenin also increased in response to D206008 treatment.Conclusion: Taken together, these data indicate that D206008 promotes melanin synthesis by stimulating the nuclear translocation of β-catenin, which activates MITF transcription and eventually melanogenesis.
