The rapid development of intelligent ophthalmology research in recent years still faces some challenges in its clinical application or clinical translation process. Two important issues that urgently need to be addressed in the development of intelligent ophthalmology are: promoting clinical application and maintaining medical equity. In response to the aforementioned issues, this article analyzes the reasons and current situation of the insufficient promotion of clinical application and the potential challenges of medical equity, and proposes that promoting clinical application and maintaining medical equity are key issues in the development of intelligent ophthalmology. At the same time, it systematically proposes corresponding specific measures to promote the development of intelligent ophthalmology.

In September 2023， the Measures for Scientific and Technological Ethics Review （Trial Implementation） was issued， revising the provisions related to the simplified procedure for ethical review in Chapter 3， Section 3. This revision of these provisions provides systematic guarantees for further optimizing ethical review work， ensuring that ethical review procedure is well-regulated， and improving scientific research efficiency. The “simplified procedure” does not mean reducing the quality and requirements of the review. Instead， based on always following internationally recognized ethical standards and emphasizing not violating national laws and regulations， improving the efficiency of ethical review and subsequent research work， and promoting the development of life sciences and medical research involving humans. In practical work， it introduces numerous new opportunities and challenges for the improvement of ethics review ability， such as new tests on the judgment and decision-making power of ethics committees， how to ensure the reliability and controllability of the conditions related to the simplified review procedure， and how to determine the basic conditions for adopting the simplified review procedure for review. Therefore， to actively respond to the challenges and possible risks brought by the simplified procedure review， efforts should be made to achieve three “unifications”， including the unification of researchers’ moral autonomy and the heteronomy of supervision implemented by relevant departments； the unification of the standard formulation of the simplified procedure review and the review work in practice； and the unification of ethical responsibility and legal responsibility.

Exosomes are ubiquitous in all types of body fluids, exhibiting a high degree of abundance and diversity. Given their distinctive structure and function, exosomes are involved in a range of life activities, including intercellular communication, material transport, and immune regulation. An increasing number of studies have identified exosomes as a source of diagnostic markers for diabetic retinopathy. Furthermore, exosomes represent a novel avenue for therapeutic intervention, with promising clinical applications. This paper examines the diagnostic and therapeutic mechanisms of exosomes in diabetic retinopathy, reviews the advancements in exosomes-based diagnostics and therapeutics for diabetic retinopathy, and aims to enhance the precision and efficiency of clinical diagnosis and treatment of diabetic retinopathy.

Glaucoma is an eye disease characterized by pathologically elevated intraocular pressure, optic nerve atrophy, and visual field defects, which can lead to irreversible vision loss. In recent years, the rapid development of artificial intelligence(AI)technology has provided new approaches for the early diagnosis and management of glaucoma. By classifying and annotating glaucoma-related images, AI models can learn and recognize the specific pathological features of glaucoma, thereby achieving automated image analysis and classification. Research on glaucoma imaging classification and annotation mainly involves color fundus photography(CFP), optical coherence tomography(OCT), anterior segment optical coherence tomography(AS-OCT), and ultrasound biomicroscopy(UBM)images. Color fundus photography is primarily used for the annotation of the optic cup and disc, OCT is used for measuring and annotating of the thickness of the retinal nerve fiber layer, and AS-OCT and UBM focus on the annotation of the anterior chamber angle structure and the measurement of anterior segment structural parameters. To standardize the classification and annotation of glaucoma images, enhance the quality and consistency of annotated data, and promote the clinical application of intelligent ophthalmology, this guideline has been developed. This guideline systematically elaborates on the principles, methods, processes, and quality control requirements for the classification and annotation of glaucoma images, providing standardized guidance for the classification andannotation of glaucoma images.

OBJECTIVE: To observe the clinical efficacy of Daoqi (directing qi flowing) acupuncture technique in Huangdi Neijing (Yellow Emperor's Inner Classic) for moderate-to-severe obstructive sleep apnea-hypopnea syndrome (OSAHS). METHODS: Sixty patients with moderate-to-severe OSAHS were randomly divided into a Daoqi acupuncture group (30 cases) and a conventional acupuncture group (30 cases, 1 case dropped out). In the Daoqi acupuncture group, Daoqi acupuncture technique in Huangdi Neijing was applied at Shanglianquan (Extra), Fengfu (GV16), and bilateral Lieque (LU7), Zhaohai (KI6); in the conventional acupuncture group, conventional acupuncture was applied at Shanglianquan (Extra), Fengfu (GV16), Yamen (GV15), and bilateral Lieque (LU7), Zhaohai (KI6), Zusanli (ST36), Fenglong (ST40). The treatment was adopted once every other day, 3 times a week, 4 weeks as one course and 3 courses were required totally in both groups. Before and after treatment, the polysomnography (PSG) indexes [apnea-hypopnea index (AHI), hypopnea index (HI), apnea index (AI), longest apnea duration, lowest nocturnal SaO₂ (LSaO₂)], and scores of Epworth sleepiness scale (ESS), Pittsburgh sleep quality index (PSQI), World Health Organization quality of life-BREF (WHOQOL-BREF) were observed, and the clinical efficacy was evaluated after treatment in the two groups. RESULTS: After treatment, the AHI, HI, AI and longest apnea duration were reduced compared with those before treatment in the two groups (P<0.01), the LSaO₂ was increased in the Daoqi acupuncture group (P<0.01); in the Daoqi acupuncture group, the AHI, HI, AI and longest apnea duration were lower than those in the conventional acupuncture group (P<0.05), and the LSaO₂ was higher than that in the conventional acupuncture group (P<0.05). After treatment, the ESS and PSQI scores were decreased compared with those before treatment (P<0.01), while the WHOQOL-BREF scores were increased compared with those before treatment (P<0.01) in the two groups; in the Daoqi acupuncture group, the ESS and PSQI scores were lower than those in the conventional acupuncture group (P<0.05, P<0.01), and the WHOQOL-BREF score was higher than that in the conventional acupuncture group (P<0.05). The total effective rate was 93.3% (28/30) in the Daoqi acupuncture group, which was higher than 82.8% (24/29) in the conventional acupuncture group (P<0.01). CONCLUSION Daoqi acupuncture technique in Huangdi Neijing can effectively treat moderate-to-severe OSAHS patients, improve the clinical symptoms and quality of life, and has the advantages i.e. simpler acupoints selection and gentler stimulation.

OBJECTIVE: To explore the effectiveness of primary interventional revascularization combined with secondary perforator composite flap in the treatment of peripheral arterial disease (PAD) accompanied by soft tissue defects around the ankle. METHODS: Between January 2022 and January 2025, 12 patients with PAD and soft tissue defects around the ankle were admitted. Among them, there were 9 males and 3 females; their ages ranged from 52 to 82 years, with an average of 68.9 years. The causes of injury included 4 cases of traffic accident, 5 cases of falls, 1 case of falling from height, 1 case of foreign body puncture injury, and 1 case of electric shock injury. The infection duration ranged from 1 month to 35 years, with a median duration of 3.5 months. The wound size ranged from 5.5 cm×3.0 cm to 15.0 cm×9.0 cm. The ankle-brachial index (ABI) was 0.32±0.12. The visual analogue scale (VAS) score for pain was 3.3±0.5. Preoperative vascular stenosis assessment was performed in all patients, with primary intervention to dredge large and medium-sized arteries, followed by secondary repair of the wound using a perforator composite flap. The flap size ranged from 6.5 cm×4.0 cm to 16.0 cm×10.0 cm. The donor sites were sutured directly or repaired with skin grafts. After two stages of treatment, the effectiveness was evaluated by measuring ABI, observing flap survival and wound healing, assessing VAS scores, and American Orthopedic Foot and Ankle Society (AOFAS) scores. RESULTS: All 12 cases completed two stages of treatment; all patients were followed up after the second-stage treatment, with a follow-up period ranging from 7 to 28 months, with an average of 16.8 months. After the first-stage treatment, the skin temperature around the ankle was significantly higher than that before treatment, and the ABI increased to 0.71±0.07, with a significant difference ( t=9.918, P<0.001). After the second-stage treatment, the blisters on the distal end of the skin flap occurred in 3 cases. The flaps survived and the wounds healed, with a healing time ranging from 10 to 14 days (mean, 11.8 days). The incisions at the donor site healed by first intention, and the skin grafts survived. The VAS score was 0.5±0.5 at 3 weeks, which was significantly lower than that before treatment ( t=13.675, P<0.001). No infection recurrence occurred during follow-up. At 6 months after the second-stage treatment, the AOFAS score of the ankle joint ranged from 92 to 97, with an average of 94.7, all reaching excellent. CONCLUSION Interventional revascularization combined with perforator composite flap for staged treatment of PAD with ankle soft tissue defects can obtain good effectiveness, by unclogging the main blood vessels, improving lower limb blood supply, and improving the survival rate of the skin flap.

Negative logarithm of the acid dissociation constant (pK _a) significantly influences the absorption, distribution, metabolism, excretion, and toxicity (ADMET) properties of molecules and is a crucial indicator in drug research. Given the rapid and accurate characteristics of computational methods, their role in predicting drug properties is increasingly important. Although many pK _a prediction models currently exist, they often focus on enhancing model precision while neglecting interpretability. In this study, we present GraFpK _a, a pK _a prediction model using graph neural networks (GNNs) and molecular fingerprints. The results show that our acidic and basic models achieved mean absolute errors (MAEs) of 0.621 and 0.402, respectively, on the test set, demonstrating good predictive performance. Notably, to improve interpretability, GraFpK _a also incorporates Integrated Gradients (IGs), providing a clearer visual description of the atoms significantly affecting the pK _a values. The high reliability and interpretability of GraFpK _a ensure accurate pK _a predictions while also facilitating a deeper understanding of the relationship between molecular structure and pK _a values, making it a valuable tool in the field of pK _a prediction.
