05).Hypoxic exposure for 12h also resulted in significantly lowered expression of HIF1

protein in U251 cells (

< 0.05).Overexpression of MEG3 obviously suppressed the proliferation and invasiveness of U251 cells (

< 0.05).

MEG3 overexpression inhibits the proliferation and invasion of U251 cells through suppressing the expression of HIF1

mRNA and protein, suggesting that MEG3 may serve as a potential therapeutic target for glioblastomas.

To evaluate the value of fundus autofluorescence (FAF) imaging combined with spectral domain optical coherence tomography (SD-OCT) in diagnosis, prognostic assessment and follow-up observation of acute Vogt-KoyanagiHarada (VKH) disease.

Clinical data were collected from 12 patients (23 eyes) with acute VKH disease treated in our hospital from May, 2018 to November, 2019, including detailed medical history, best corrected visual acuity (BCVA), and results of slit lamp biomicroscopy, fundus photography, SD-OCT, fundus fluorescein angiography (FFA) and FAF imaging.SDOCT and FAF imaging were repeated after a course of treatment and in follow-up examination, and the results were compared with those at the time of admission.

VKH disease involved both eyes in 11 patients (91.7%).Fundus photography showed optic disc edema in 16 eyes (69.6%), and multiple retinal neuroepithelial detachment was detected by SD-OCT in all the involved eyes (100%).IN all the eyes, FFA revealed small and dense fluorescein leakage in y SD-OCT (

< 0.05).

The combination of fluorescein angiography, FAF imaging and SD-OCT can significantly improve the diagnostic accuracy of VKH disease.FAF imaging combined with SD-OCT provides an effective and noninvasive modality for evaluation of remission and monitoring the changes in VKH disease.

To evaluate the effect of general anesthesia on postoperative melatonin secretion in 4-to 6-year-old children with snoring.

Twenty children with snoring aged 4-6 years of either gender (ASA grade Ⅰ and Ⅱ) were selected for adenoidectomy.Before, during and 3 days after the operation, salivary melatonin levels of the children were measured at 11 selected time points (T1-T11).The illumination intensity and body temperature of the children were recorded at each time point of measurement.The sleep time of the children in 3 days after the operation was recorded, and postoperative pain scores (FLACC) and Riker and Rehabilitation Quality Rating Scale-15(QoR-15) scores were assessed.Sleep Apnea Life Quality Evaluation Questionnaire (OSA-18) was used to evaluate postoperative recovery of the children at 28 days after the operation.The incidence of major adverse events of the children during hospitalization was recorded.

No significant difference was found in baseline salivary melatonin level among the 20 children not cause significant changes in melatonin secretion to cause disturbance of the circadian rhythm in these children.

In preschool children with snoring, general anesthesia affects but does not inhibit melatonin secretion on the first night after surgery, and minor surgeries under general anesthesia in the morning do not cause significant changes in melatonin secretion to cause disturbance of the circadian rhythm in these children.

To investigate the value of hand-held retinal optometer and optical coherence tomography (OCT) in predicting postoperative visual acuity in patients with age-related cataract and idiopathic macular epiretinal membrane.

We retrospectively analyzed the data of patients undergoing phacoemulsification combined with intraocular lens implantation for age-related cataract in our hospital from January, 2019 to April, 2020.Preoperative examination detected idiopathic macular epiretinal membrane in 45 of the patients (52 eyes) with lens opacity grade C2N2P1 according to LOCSⅡ lens opacity classification criteria.Based on the thickness of the macular fovea, the eyes were divided into group A (9 eyes) with macular thickness < 300 μm by OCT examination, group B (25 eyes) with macular thickness of 300 to 400 μm, and group C (18 eyes) with macular thickness >400 μm.The best corrected visual acuity and retinal visual acuity before operation and the best corrected visual acuity on the first day and at 3 months aftern accurately assess postoperative vision in patients with stage C2N2P1 cataract.Patients with a macular thickness >400 μm caused by idiopathic macular epiretinal membrane are likely to have poor postoperative visual outcomes.

To investigate the effects of restrictive fluid management in patients with severe traumatic brain injury (sTBI).

Between January, 2019 and June, 2020, we randomly assigned 51 postoperative patients (stay in the ICU of no less than 7 days) with sTBI into treatment group (

=25) with restrictive fluid management and the control group (

=26) with conventional fluid management. link2 The data of optic nerve sheath diameter (ONSD), middle cerebral artery pulsatility index (MAC- PI), neuron-specific enolase (NSE) level, inferior vena cava (IVC) diameter, Glascow Coma Scale (GCS) score, mean arterial blood pressure, heart rate, and fluid balance of the patients were collected at ICU admission and at 1, 3 and 7 days after ICU admission, and the duration of mechanical ventilation, ICU stay, and 28-day mortality were recorded.

The cumulative fluid balance of the two groups were positive on day 1 and negative on days 3 and 7 after ICU admission; at the same time points, the patients in the treatment group had signific0.05).

Restrictive fluid management can reduce cerebral edema and improve the prognosis but does not affect the 28-day mortality of patients with sTBI.

To investigate accuracy of the currently used strategies for intraocular pressure measurements for reflecting actual 24-hour intraocular pressure fluctuations.

From September, 2018 to January, 2019, the patients with a suspected diagnosis of primary open angle glaucoma at our hospital were prospectively enrolled to receive 24-hour intraocular pressure monitoring using a Goldmann tonometer. With the intraocular pressure measurements at 000, 200, 500, 700, 800, 1000, 1100, 1400, 1600, 1800, 2000, and 2200 as the gold standard (strategy 1), we compared the measurements taken at 500, 700, 1000, 1400, 1800, and 2200 (strategy 2) and at 800, 1100, 1400, and 1600 (strategy 3) for their accuracy in reflecting 24-h intraocular pressure fluctuations.

A total of 41 patients (82 eyes) were enrolled in this study. The peak intraocular pressures measured using the 3 strategies were 21.09±4.15 mmHg, 20.54±4.10 mmHg, and 19.91±4.38 mmHg, respectively, showing significant differences among them (

< 0.05). The trough intraocular pressures measured by the 3 strategies were also significantly different (13.93±3.38 mmHg, 14.63±3.49 mmHg, and 15.46±3.63 mmHg, respectively;

< 0.05). The co-occurrence of the peak intraocular pressure was 74.39% between strategies 1 and 2 and 43.90% between strategies 1 and 3. The sensitivity of strategies 2 and 3 for detecting 24-h intraocular pressure fluctuations was 55.56% and 36.11%, respectively.

For suspected cases of glaucoma, intraocular pressure measurements at 4 and 6 time points of a day can not precisely reflect the actual range of intraocular pressure fluctuations, and may lead to a missed diagnosis of glaucoma.

To explore the mechanism by which ginsenoside 20(S)-Rg3 upregulates the expression of tumor suppressor von Hippel-Lindau (VHL) gene in ovarian cancer cells.

Ovarian cancer cell line SKOV3 treated with 20(S)-Rg3 were examined for mRNA and protein levels of VHL, DNMT1, DNMT3A and DNMT3B by real-time PCR and Western blotting, respectively. The changes in VHL mRNA expression in SKOV3 cells in response to treatment with 5-Aza-CdR, a DNA methyltransferase inhibitor, were detected using real-time PCR. VHL gene promoter methylation was examined with methylation-specific PCR and VHL expression levels were determined with real-time PCR and Western blotting in non-treated or 20(S)-Rg3-treated SKOV3 cells and in 20(S)-Rg3-treated DNMT3A-overexpressing SKOV3 cells. VHL and DNMT3A protein levels were detected by immunohistochemistry in subcutaneous SKOV3 cell xenografts in nude mice.

Treatment of SKOV3 cells with 20(S)-Rg3 significantly upregulated VHL and downregulated DNMT3A expressions at both the mRNA and protein levels (

< 0.05) and upregulated DNMT3B expression only at the mRNA level, but did not cause significant changes in either the mRNA or protein level of DNMT1. Treatment of the cells with 2 and 5 μmol/L 5-Aza-CdR obviously increased VHL mRNA expression by by over 3 folds (

< 0.05). 20(S)-Rg3 significantly decreased the methylation level in the promoter region of VHL gene, and this effect was abrogated by DNMT3A overexpression in the cells (

< 0.05). link3 Immunohistochemisty showed a significantly increased VHL expression but a lowered DNMT3A expression in subcutaneous SKOV3 cell xenografts in 20 (S)-Rg3-treated nude mice.
