Objective:To observe the multimodal imaging features of retinal diseases associated with COVID-19.Methods:A retrospective case study. Sixteen patients (30 eyes) of retinal diseases associated with COVID-19 admitted to the Ophthalmology Department of the Second People's Hospital of Zhengzhou in December 2022 were included in the study. There were 5 males and 11 females, with the mean age of (26.69±9.88) years; 14 patients were bilateral and 2 patients were unilateral. The time of ocular symptoms after the diagnosis of COVID-19 was (2.63±0.89) days. All patients underwent the examinations of best corrtected visual acuity (BCVA), fundus color photography (FP), infrared fundus photography (IR), optical coherence tomography (OCT). Fluorescein fundus angiography (FFA) was performed in 2 patients (4 eyes). There were 20 eyes with acute macular neuroretinopathy (AMN), including 6 eyes with cotton wool spots; 10 eyes with Purtscher-like retinopathy (PLR). The BCVA of the patients was 0.1-1.0. No obvious abnormality was found in anterior segment examination. The features of FP, IR and OCT were analyzed retrospectively.Results:In 20 eyes of AMN, irregular reddish brown lesions in the central or paracentral area of the macula in 14 eyes; FP showed no obvious abnormality in 6 eyes; IR showed irregular map like low reflection in the central or paracentral area of macular in all eyes; OCT showed hyperreflectivity in outer plexiform layer and outer nuclear layer, hyporeflectivity in the ellipsoid zone and photoreceptor layers in all eyes; no abnormal fluorecence was observed in 2 eyes examined by FFA. In 10 eyes with PLR, cotton wool spots and retinal hemorrhage were observed in the posterior pole and/or peripapillary area, and the peripheral retina was generally normal, Purtscher spot was found in 5 eyes and macular edema in 4 eyes; OCT showed strong reflex signal in neuroepithelial layers, edema in neuroepithelial layers in 6 eyes; in the 2 eyes examined by FFA, fluorescein leakage from the retinal vein wall was observed, the posterior pole and peripapillary area retinal arteriole occlusions showed patchy hypofluorescence, the fluorescence was obscured by retinal hemorrhage below at inferior retina.Conclusions:For AMN associated with COVID-19, IR can show the lesion contour, OCT shows lesions in the outer retina. PLR associated with COVID-19 are usually at the posterior pole and/or peripapillary area in FP, OCT shows neurocortical edema.

AIM:This study aims to investigate the impact of nobiletin(NOB)on the gut microbiota and short-chain fatty acids(SCFAs)in high-fat diet-induced obese rats.METHODS:A total of 22 SD rats were randomly di-vided into the control(CON)group and high-fat diet(HFD)group.The HFD induced obesity,upon successful modeling,the rats were further divided into the HFD and NOB group,each group consisting of 6 rats.The NOB group received nobi-letin solution(100 mg·kg-1·d-1)via gavage for 21 consecutive days.Body weight was measured bi-daily,and hematoxylin-eosin(HE)staining was employed to observe pathological changes in adipose tissue and liver.Serum lipid levels were as-sessed using an auto-biochemical analyzer.Analysis of the gut microbiota was performed using 16S ribosomal RNA(rRNA)sequencing,while high-performance liquid chromatography mass spectrometry(LC-MS)was used to determine SCFAs levels in rat feces.RESULTS:Compared with CON group,HFD-fed demonstrated a substantial increase in body weight(P<0.01),accompanied by an augmentation in adipocyte diameter and the presence of hepatic cell vacuolization,indicative of cellular steatosis and inflammation.Moreover,there was a notable elevation in TG and TC levels(P<0.05).At the phylum level,the HFD rats exhibited an altered composition,characterized by an increase in Firmicutes and a con-current decrease in Bacteroidetes.At the genus level,Bacteroides,Lactobacillus and Blautia experienced a significant de-crease,while Colidextribacter showed an increase.Notably,there was a substantial reduction in the expression of propion-ic acid and butyric acid.In comparison to the HFD group,rats administered with NOB demonstrated a marked decrease in body weight(P<0.05),a reduction in adipocyte diameter,and an amelioration in hepatic cell vacuolization and cellular steatosis.Furthermore,TG and TC levels exhibited a significant decrease(P<0.05).At the phylum level,Firmicutes de-creased,and Bacteroidetes increased.At the genus level,Bacteroides,Lactobacillus and Blautia exhibited a significant in-crease,while Colidextribacter displayed a decrease.Additionally,there was an up-regulation of propionic acid and butyric acid levels in the NOB group.CONCLUSION:Nobiletin,through its multifaceted actions,demonstrates a potential anti-obesity effect by effectively reducing body weight in obese rats.This includes the regulation of gut microbiota structure,modulation of SCFAs content,and enhancement of lipid metabolism.

Objective:To explore the effects of WeChat-based health education on management of hypertensive outpatients under medical consortium.Methods:Totally 180 hypertensive patients who attended the Multidisciplinary Clinics of Beijing Anzhen Hospital, Capital Medical University, and Datun Community Health Service Center from communities under our medical consortium from November 2018 to April 2019 were selected and divided into the observation group ( n=91) and the control group ( n=89) according to the visit time. Patients in the control group received routine health education, while patients in the observation group received WeChat-based health education under medical consortium for 6 months. The self-management ability (using Hypertension Patients Behavior Rating Scale, HPSMBRS) , treatment compliance (using Therapeutic Adherence Scale for Hypertensive Patients, TASHP) , the 24 h average systolic and diastolic blood pressure, the average systolic and diastolic blood pressure at daytime, and the average systolic blood pressure and diastolic blood pressure at night were compared between the two groups. Results:After the intervention, the diet management, medication management, disease monitoring, exercise management, work and rest and emotional management scores of the observation group were higher than those of the control group, and the differences were statistically significant ( P<0.05) . After the intervention, the medication-taking behavior, bad medication-taking behavior, daily activity management behavior and tobacco and alcohol addiction scores were higher than those of the control group, and the differences were statistically significant ( P<0.05) . After the intervention, the 24 h average systolic and diastolic blood pressure, average systolic and diastolic blood pressure at daytime and average systolic and diastolic blood pressure at night decreased in the observation group, and the differences were statistically significant compared with the control group ( P<0.05) . Conclusions:The WeChat platform under medical consortium provides standardized, consistent, continuous and effective health education, which can improve the self-management ability and treatment compliance of hypertensive outpatients, and can effectively control blood pressure levels. It shows sound effects in clinical use.

Objective:To evaluate the association between the use of emergency medical services (EMS) and the severity of disease among patients admitted to the emergency room, to analyze the characteristics of the patients, and to build prediction model providing evidence-based use of EMS resources.Methods:The data of patients admitted to the Emergency Room of the First Affiliated Hospital of University of Science and Technology of China from January 2020 to July 2021 were extracted from the Chinese Emergency Triage Assessment and Treatment (CETAT) database. Patients were divided into the EMS use group (AB+ group) and self-seeing group (AB-group) according to whether they used EMS. The patients’ general condition, vital signs and laboratory tests results were recorded. The severity of patients’ condition was judged based on whether the patient was admitted to the department of critical medicine, specialized care unit, emergency operation and/or emergency percutaneous intervention. A 9-variable model that did not require laboratory inspection and 22-variable model that required laboratory inspection were established to correct the propensity score to analyze the correlation between the severity of disease and the EMS use. In the subgroup analysis, the correlation between the EMS use and severity of the patients was analyzed according to the reason of the patient’s visit.Results:During the study period, 16 489 patients were admitted to the emergency room, and 6975 patients were finally enrolled in this study. There were 2768 patients (39.7%) in the AB+ group and 4207 patients (60.3%) in the AB-group. In the AB+ group 522 patients (18.9%) were in high risk, and in the AB-group 563 patients (13.4%) were in high risk. Compared with the AB-group, patients in the AB+ group were older and had a higher proportion of coma, a faster autonomic heart rate, and a lower diastolic blood pressure and peripheral oxygen saturation (SpO 2). In the 9-variable model, sex, consciousness, temperature, heart rate and diastolic blood pressure were associated with the EMS use. In the 22-variable model, consciousness, SpO 2, neutrophils, and albumin were the relevant factors for patients using EMS. Before the correction of propensity score, the EMS use was an independent risk factor for critically ill patients ( OR=1.5, 95% CI 1.32-1.72, P<0.001). After adjusted using 9-variable propensity score, the EMS use ratio decreased significantly compared with that without correction ( OR=1.24,95% CI 1.08-1.42, P<0.001). Interestingly, after adjusted with propensity score match with 22-variable model, there was no association between the severity of disease and t the EMS use ( OR=1.10,95% CI 0.95-1.28, P=0.195). In subgroup analysis, patients’ chief complaint of central nervous system, cardiovascular system, and trauma were the top three reasons at admission. Before the propensity score correction, the EMS calling patients with chief complaint of central nervous system, digestive system, and trauma were related to the severity of the patients. After adjusted with 9-variable model the EMS use was associated with the severity of the disease only in trauma patients, and after adjusted with 22-variable model there was no statistical difference considering the severity of the disease in all subgroups. Conclusions:The EMS use is common. However, the association of the EMS use with the severity of disease is decreased with variable models using propensity score. These findings indicate that the EMS use should be based on multivariable models, which may be important in detecting critically ill patients, optimizing the EMS use, and avoiding unnecessary call in the future.

Objective:To evaluate the efficacy and safety of oral anisodine hydrobromide tablets in the treatment of nonarteritic anterior ischemic optic neuropathy (NAION).Methods:A multicenter nonrandomized controlled trial was conducted.A total of 282 acute NAION patients (282 eyes) were recruited from 16 hospitals in China from July 2020 to May 2021.Patients were divided into two groups according to treatment methods, which were control group (124 cases, 124 eyes) receiving regular treatment including citicoline sodium plus Ginkgo biloba leaf liquid extract or Ginkgo biloba leaf extract tablets plus mecobalamin, and experimental group (158 cases, 158 eyes) receiving treatment in control group plus oral anisodine hydrobromide tablets 1 mg, twice daily for 2 to 3 months.Best corrected visual acuity (BCVA), visual field index (VFI), peripapillary retinal nerve fiber layer (pRNFL) and radial peripapillary capillary vessel density (RPC) were assessed at 1, 2, 3, and 6 months after enrollment using the standard decimal visual acuity chart, 750i Humphery visual field analyzer, Cirrus HD-OCT 4000/Cirrus HD-OCT 5000, RTVue-XR optical coherence tomography respectively.The primary outcomes were BCVA and VFI, and the secondary outcomes were pRNFL, RPC, and the side effects during the follow-up.The study adhered to the Declaration of Helsinki.All patients were fully informed about the treatment and purpose of this study and voluntarily signed the informed consent form.The study protocol was approved by Chinese PLA General Hospital (No.S2020-021-01). Results:In all, 242 patients (242 eyes) completed the follow-up of BCVA, and 98 patients (98 eyes) completed the VFI follow-up.In terms of visual function, BCVA and VFI improved significantly over time in the two groups, and BCVA and VFI were better in experimental group than in control group at various follow-up time points (all at P<0.05). In terms of structure, pRNFL gradually decreased in both groups with the extension of treatment, and pRNFL was significanthy thinner in experimental group than in control group at various follow-up time points (all at P<0.05). There was no significant difference in RPC between the two groups at the last follow-up ( P>0.05). There were two cases with side effects and one case was discontinued due to side effects 25 days after enrollment. Conclusions:Oral anisodine hydrobromide can improve visual acuity and visual field in NAION and accelerate the regression of optic disc edema, with good safety.
