AIM: To observe the manifestations and distribution patterns of visual field in non-arteritic anterior ischemic optic neuropathy(NAION).METHODS: Retrospective observational study. The investigation encompassed 183 patients(246 eyes)diagnosed with NAION who were evaluated at the Neuro-Ophthalmology/Acupuncture Department within the Eye Hospital, China Academy of Chinese Medical Sciences from June 2018 to December 2023. Recorded clinical data covered demographic details, incidence, disease duration, presence of systemic diseases, and histories of tobacco and alcohol use, along with best-corrected visual acuity(BCVA), visual field index(VFI), type of visual field defect, and thickness of the peripapillary retinal nerve fiber layer(pRNFL).RESULTS: A total of 183 patients(246 eyes)were enrolled. The cohort consisted of 101 males and 82 females; 120 exhibited unilateral symptoms, while 63 showed bilateral symptoms, with a mean age of 56.20±9.78 years(range 29-81 years). The types of visual field defects observed were varied: 90 eyes(36.6%)had diffuse loss, 63 eyes(25.6%)experienced inferior hemifield loss, 32 eyes(13.0%)displayed ring scotomas, 22 eyes(8.9%)had arcuate scotomas, 11 eyes(4.5%)presented with quadrant defects, 15 eyes(6.1%)had sectorial or wedge defects, and 13 eyes(5.3%)showed superior hemifield loss. The BCVA(LogMAR)and VFI of patients with diffuse visual field loss were poorer than patients with other types of visual defects(all P<0.05). There were statistically significant differences in visual field defects among patients of different genders and ages(all P<0.05). However, history of hypertension, diabetes, hyperlipidemia, sleep apnea and other systemic diseases, history of smoking and alcohol, and course of disease did not show specificity in the NAION visual field(all P>0.05).CONCLUSION:NAION manifests with a broad spectrum of visual field impairments across different genders, age, and levels of visual functionality. Extensive future research is necessary to identify additional reasons influencing the types of visual field damage in NAION.

ObjectiveTo evaluate the effects of Shenling Guben Granules on quality of life and immune function in patients with HIV classified as immunological non-responders （INRs）. MethodsA prospective， multicenter， randomized， double-blind， controlled trial was conducted from August 21， 2018， to January 6， 2021， across eight hospitals in China. A total of 300 INR patients， diagnosed with spleen-kidney yang deficiency or lung-spleen Qi deficiency syndromes， were enrolled and randomly assigned to either the observation group or the control group， with 150 patients in each group. The control group received antiretroviral therapy （ART） combined with placebo， while the observation group received ART combined with Shenling Guben Granules. After 72 consecutive weeks of treatment， the World Health Organization Quality of Life for HIV brief version （WHOQOL-HIV BREF） was used to assess quality of life before and after treatment in both groups. Immune indicators （CD4⁺ and CD8⁺ T cell counts）， complete blood count， liver and renal function， and adverse events during treatment were also evaluated to assess safety. ResultsA total of 279 patients were included in the final analysis （140 in the observation group and 139 in the control group）. After treatment， CD4⁺ T cell counts in the observation group increased significantly compared to baseline （P< 0.05）， whereas the control group showed an upward trend without statistical significance. Compared with the control group after treatment， the observation group showed a significantly greater increase in CD4⁺ levels （P<0.05）. There were no significant differences in the total score or domain scores of quality of life （physical， psychological， independence， social relationships， environment， and spirituality）， or in CD8⁺ T cell counts， before and after treatment in either group. The incidence of adverse events during treatment was 10% （14/140） in the observation group and 10.07% （14/139） in the control group， with no statistically significant difference between the two groups. ConclusionAlthough Shenling Guben Granules did not significantly improve quality of life in INR patients， they significantly increased CD4⁺ cell counts and demonstrated good safety， providing scientific evidence to support their use as a treatment option for INR patients.

Objective:To observe the clinical characteristics of non arteritic anterior ischemic optic neuropathy (NAION) in patients of different genders.Methods:A retrospective clinical analysis. A total of 183 cases (246 eyes) of NAION with complete diagnosis and treatment confirmed by Departments of Neuro-ophthalmology/Acupuncture and Moxibustion of Eye Hospital, China Academy of Chinese Medical Sciences from June 2018 to December 2023 were included. Among them, 101 cases (138 eyes) were male and 82 cases (108 eyes) were female. Their age was (59.2±9.8) years. The number of right and left eyes were 120 and 126, respectively. The patient's gender, age, disease course, history of hypertension, history of diabetes, history of hyperlipidemia, history of smoking and drinking, best corrected visual acuity (BCVA), intraocular pressure, and peripapillary Retinal Nerve Fiber Layer (pRNFL) thickness were recorded in detail. Visual field defects were classified into diffuse defects, ring scotoma, fan-shaped or wedge-shaped defects, upper and lower half defects, arcuate scotoma, and quadrantanopia. Logistic regression analysis was utilized to determine whether gender was an independent factor affecting the degree of visual field impairment in NAION.Results:Compared with female patients, male patients showed earlier onset age, a shorter interval between binocular onsets, a higher morbidity rate of hyperlipidemia, and a higher proportion with history of smoking and drinking, with statistically significant differences ( P<0.05). There was no statistically significant difference in disease duration, intraocular pressure, pRNFL thickness, and intraocular perfusion pressure between patients of different genders ( P>0.05). Female patients exhibited better BCVA than male patients, but the difference was not statistically significant ( P>0.05). The degree of visual field impairment in female patients was significantly better than that in males. Males' visual field defects were mostly in the lower half, while females' defects were mostly of arcuate scotoma, with statistically significant differences ( P<0.05). The results of multiple logistic regression analysis showed that the gender of male was an independent risk factor for severe visual field impairment in NAION patients (odds ratio=2.936, 95% confidence interval 1.275-6.763, P=0.011). Conclusions:Male NAION patients have an earlier onset age and a shorter interval between the initial and contralateral eye onset. Male patients exhibit a more severe degree of visual field impairment, which is mostly manifested as lower half visual field defect. While female patients tend to develop arcuate scotoma. After adjusting for other influencing factors, the gender of male remains an independent risk factor for severe visual impairment in NAION patients.

Diabetic retinopathy(DR)is one of the most common retinal complications of diabetes could cause irreversible loss of central vision in the working-age population. Current studies showed that systemic risk factors, inflammatory response, and oxidative stress played a central role in the development of DR. Although traditional sequencing methods have provided valuable insights into the pathogenesis of DR, offering crucial guidance for clinical diagnosis and treatment, they still possess certain limitations. In recent years, the emerging single-cell RNA sequencing technology(scRNA-seq)has enabled precise analysis of mRNA transcriptomes at the single-cell level. This technique accurately identifies novel cell subtypes in retinal diseases, detects rare cells, and reveals intercellular heterogeneity. It contributes to elucidating the pathogenesis and development of retinal diseases, and facilitates exploration of gene regulatory relationships associated with these disorders to provide valuable insights for future precision medicine. This article reviews the technology of single-cell sequencing and its application in DR research. It also explores the mechanisms of different types of cells associated with DR, aiming to enhance the utilization of scRNA-seq in DR research and identify potential therapeutic targets to improve clinical diagnosis and treatment of DR.

Healthy lifestyles and good living habits are effective strategies and important approaches to prevent chronic non-communicable diseases. With the development of evidence-based medicine, the evidence translation system has made some achievements in clinical practice. There is, however, no comprehensive, professional and efficient system for translating lifestyle evidence globally. Therefore, the Health Lifestyle Evidence (HLSE) Group of Lanzhou University constructed the HLSE Evidence Translation System (https://hlse.cn/), with the aim of synthesizing, evaluating, translating, and applying lifestyle-related evidence resources. This paper aims to introduce the functional module design of the evidence translation system, the system development process and testing, introduce the interface design and function demonstration, and explain the significance of constructing the HLSE.

Objective:To identify and analyze the genuine medicinal plant Gentiana scabra Bge. from 9 regions in Liaoning Province using DNA barcode technology based on the base sequence of internal transcribed spacer. Methods:DNA was extracted from the medicinal parts of 26 Gentiana scabra Bge. samples by using DNA kit extraction method. The ITS sequence was amplified through polymerase chain reaction (PCR), and then two-way sequencing was carried out. Other sources and outgroup sequences of the medicinal plant Gentiana scabra Bge. were downloaded from Genbank. After the sequencing results were spliced by using SeqMan 7.1.0 software, MEGA 7.0 software was used to analyze and compare the data, and calculate the genetic distance of K2P (Kimura 2-parameter). The phylogenetic tree was established by Neighbor-Joining (NJ) method for analysis. Results:According to the results of NJ cluster tree, all Gentiana scabra Bge. samples from different sources were clustered into one large branch, and Gentiana scabra Franch. and Gentiana triflora Pall. were clustered into one branch respectively, with obvious differences; Gentiana scabra and Gentiana manshurica Kitag. were clustered into one branch, and the genetic relationship was relatively close. In combination with the variation site and genetic distance, the base sequences of Gentiana scabra and Gentianamanshurica were very similar, and the interspecific differences were very small. Except for the intraspecific variation of only one sample collected in Liaoning Province, the base sequences of the other samples were the same, and there was no difference between " Gentiana scabra Bge. in Qingyuan" and Gentiana scabra Bge. samples from other regions in Liaoning Province. Conclusion:The DNA barcode technology of ITS sequence can be used to differentiate and identify medicinal plant Gentiana scabra Bge. and its original plants from different sources with a high success rate.

Objective:To use rbcL sequences to identify the rhizomes of the Liaoning collection of Atractylodes chinensis (DC.) Koidz.; To provide a basis for ensuring the feasibility of cultivation of the native herb in Liaoning Province. Methods:A total of 30 rhizomes of Atractylodes chinensis (DC.) Koidz. were collected from 10 regions cultivated in Liaoning Province, and the total DNA was extracted. DNA barcodes were screened by PCR, and the rbcL sequences of the samples were amplified and sequenced, and the amplification and sequencing success rates were calculated. Sequence alignment was performed using MEGA 7.0 software; a systematic clustering tree was constructed using the neighbour-joining method. Results:The success rates of DNA extraction from the rhizomes of Atractylodes chinensis (DC.) Koidz. were all 93.3%, and the success rates of PCR amplification and sequencing were all 100%. Among the 30 samples of Atractylodes chinensis (DC.) Koidz. in Liaoning Province, two samples had intraspecific variation, and the rest of the base sequences of Atractylodes chinensis (DC.) Koidz. were identical. Atractylodes chinensis (DC.) Koidz. was closer to the herbs of the genus Cangzhu, a relative species of Asteraceae, and was genetically more distant from the rest of Asteraceae. The NJ tree could distinguish Atractylodes chinensis (DC.) Koidz. and its relatives. Conclusion:The quality of Atractylodes chinensis (DC.) Koidz. cultivars in Liaoning Province is basically similar, and the rbcL sequence can be used as a valid sequence fragment for the identification of Atractylodes chinensis (DC.) Koidz. DNA barcode.

Objective:To investigate the effect of clinical practice of evidence-based medicine (EBM) in facilitating the essential competent capability of ultrasound medicine residents.Methods:A total of 39 residents undergoing standardized residency training in the Department of Ultrasound Medicine at the Second Affiliated Hospital of Zhejiang University School of Medicine from October 2021 to October 2024 were randomly assigned into two groups: control group (19 residents) and an evidence-based traceability group (20 residents). The two groups received same EBM theoretical teaching materials, however, the evidence-based traceability group was additionally required to complete a clinical practice component in ultrasound medicine as part of their EBM curriculum. A comparison was made between the two groups at the conclusion of the teaching cycle with respect to self-assessment (EBM attitude, skills, knowledge), objective test (case analysis, theoretical knowledge), and teaching satisfaction.Results:After the teaching period, the evidence-based traceability group exhibited significantly elevated self-assessment scores in both EBM theoretical knowledge and practice skills when compared to the control group with scores of (26.70±1.17)score vs (21.37±4.15)score and (22.40±1.39)score vs (17.79±3.15)score, respectively (both P<0.001). In the objective test (case analysis, theoretical knowledge), the evidence-based traceability group scored higher in case analysis relevant to clinical scenarios compared to the control group[(59.55±4.56) score vs (52.11±6.58) score, P<0.001], while no statistically significant difference was observed in theoretical knowledge[(29.00±3.08) score vs (27.89±4.19) score, P=0.357]. Both groups reported high teaching satisfaction, with no significant difference between groups ( P>0.05). Conclusions:The incorporation of clinical practice in EBM education for ultrasound medicine residents enhances their clinical practice abilities and improves their analytical and problem-solving skills in real clinical scenarios, contributing to the development of general competent capability among residents.
