Piezo1, a mechanosensitive nonselective cation channel characterized by multiple transmembrane domains, plays a critical role intransducing mechanical stimuli at the cellular membrane and participates in various physiological and pathological processes. Recent studies have established a significant association between Piezo1 and the occurrence and development of multiple ophthalmic disorders. Substantial evidence demonstrates that Piezo1 contributes to ocular disease progression by regulating fundamental cellular processes including proliferation, differentiation, apoptosis, and inflammatory responses, with particular relevance to glaucoma, corneal diseases, retinal disorders, and dry eye syndrome. Piezo1 has made rapid progress in ophthalmology, and has been established as an important mechanosensor in the eye, widely involved in intraocular pressure regulation, retinal function maintenance, corneal homeostasis and repair, and ocular development, and its dysfunction is closely related to the pathological mechanisms of many important blinding eye diseases. Consequently, Piezo1 is not only a key molecule for understanding ocular mechanobiology, but also represents a highly promising therapeutic target. Its study offers new perspectives for the development of novel therapeutic strategies against ocular diseases. This review systematically summarizes current research advances regarding Piezo1 channels in ophthalmology, analyzes their mechanistic involvement in disease processes, and evaluates their potential therapeutic value, thereby offering innovative perspectives for the clinical management of ocular diseases.

OBJECTIVE:
As an age-related neurodegenerative disease, the prevalence of mild cognitive impairment (MCI) increases with age. Within the framework of traditional Chinese medicine, spleen-kidney deficiency syndrome (SKDS) is recognized as the most frequent MCI subtype. Due to the covert and gradual onset of MCI, in community settings it poses a significant challenge for patients and their families to discern between typical aging and pathological changes. There exists an urgent need to devise a preliminary diagnostic tool designed for community-residing older adults with MCI attributed to SKDS (MCI-SKDS).
METHODS:
This investigation enrolled 312 elderly individuals diagnosed with MCI, who were randomly distributed into training and test datasets at a 3:1 ratio. Five machine learning methods, including logistic regression (LR), decision tree (DT), naive Bayes (NB), support vector machine (SVM), and gradient boosting (GB), were used to build a diagnostic prediction model for MCI-SKDS. Accuracy, sensitivity, specificity, precision, F1 score, and area under the curve were used to evaluate model performance. Furthermore, the clinical applicability of the model was evaluated through decision curve analysis (DCA).
RESULTS:
The accuracy, precision, specificity and F1 score of the DT model performed best in the training set (test set), with scores of 0.904 (0.845), 0.875 (0.795), 0.973 (0.875) and 0.973 (0.875). The sensitivity of the training set (test set) of the SVM model performed best among the five models with a score of 0.865 (0.821). The area under the curve of all five models was greater than 0.9 for the training dataset and greater than 0.8 for the test dataset. The DCA of all models showed good clinical application value. The study identified ten indicators that were significant predictors of MCI-SKDS.
CONCLUSION
The risk prediction index derived from machine learning for the MCI-SKDS prediction model is simple and practical; the model demonstrates good predictive value and clinical applicability, and the DT model had the best performance.

Traditional Chinese medicine (TCM) is a well-accepted therapy for atopic dermatitis (AD). However, there are currently no evidence-based guidelines integrating TCM and Western medicine for the treatment of AD, limiting the clinical application of such combined approaches. Therefore, the China Association of Chinese Medicine initiated the development of the current guideline, focusing on key issues related to the use of TCM in the treatment of AD. This guideline was developed in accordance with the principles of the guideline formulation manual published by the World Health Organization. A comprehensive review of the literature on the combined use of TCM and Western medicine to treat AD was conducted. The findings were extensively discussed by experts in dermatology and pharmacy with expertise in both TCM and Western medicine. This guideline comprises 23 recommendations across seven major areas, including TCM syndrome differentiation and classification of AD, principles and application scenarios of TCM combined with Western medicine for treating AD, outcome indicators for evaluating clinical efficacy of AD treatment, integration of TCM pattern classification and Western medicine across disease stages, daily management of AD, the use of internal TCM therapies and proprietary Chinese medicines, and TCM external treatments.

Objective:To analyze the CT and MRI imaging features of Kimura disease in parotid region.Methods:This study was a cross-sectional study. From January 2018 to June 2023, a total of 40 patients with Kimura disease in parotid region who were initially diagnosed and confirmed by postoperative pathology were retrospectively collected in the Ninth People′s Hospital, School of Medicine, Shanghai Jiao Tong University. There were 36 male patients and 4 female patients, with an age of (46±19) years, ranging from 8 to 74 years old. The clinical data, preoperative CT and MRI findings were analyzed. For patients undergoing MRI examination, the apparent diffusion coefficient (ADC) value of the lesion was measured, and the type of time-signal intensity curve (TIC) was analyzed.Results:The ratio of male to female patients was 9∶1, with a long clinical history (1 month to 20 years). And 37 cases (37/40, 92.5%) were associated with elevated peripheral blood eosinophils. Among the 40 cases, there were 4 cases of nodular type, 34 cases of diffuse type, and 2 cases of intermediate type. Nodular type: All lesions were located in the superficial lobe of unilateral parotid gland, and 3 cases had multiple lesions. The lesions were round, well-defined, and homogeneous in density or signal intensity. Two lesions showed hyperintensity on T 2WI and obvious homogeneous enhancement. The TIC was plateau type, and the ADC values were 0.74×10 -3 mm 2/s and 0.82×10 -3 mm 2/s. Diffuse type: The 22 cases had multiple lesions, and 20 cases had subcutaneous lesions in other parts of the head and neck. The lesions were irregular in shape and ill-defined in boundary. The adjacent subcutaneous tissue and skin were involved in 33 cases. The density or signal intensity of the lesions was heterogeneous, and among the 15 patients who underwent MRI, 14 cases showed uneven slightly hyperintensity with hypointense strips on T 2WI, moderate or significant enhancement. TIC showed a persistent pattern in 9 cases, and a plateau pattern in 6 cases. The ADC value was (0.99±0.21)×10 -3 mm 2/s. Intermediate type: The 2 cases were single, irregular in shape, without involvement of adjacent subcutaneous tissue and skin, with obvious enhancement and no necrosis. And 28 cases of diffuse type and 2 cases of nodular type were accompanied by ipsilateral or bilateral cervical lymphadenopathy. The enlarged lymph nodes had clear boundaries, homogeneous density or signal intensity, and homogeneous enhancement. Conclusions:The Kimura disease in parotid region has a long clinical course and elevated peripheral blood eosinophils. The diffuse type is more common in the morphology, with multiple ill-defined lesions in and around the parotid gland, and can be accompanied by similar subcutaneous lesions in other parts of the head and neck with obvious enhancement, accompanied by cervical lymph node enlargement. TIC shows persistent pattern or plateau type, and the ADC value is low. The nodular type and intermediate type are rare.

Ferroptosis is a novel type of iron-dependent cell death driven by lipid peroxidation. More and more evidence shows that ferroptosis is related to various pathological conditions, such as neurodegenerative diseases, diabetic nephropathy, and cancer. Ferroptosis driven by lipid peroxidation may promote or inhibit the occurrence and development of these diseases. The intracellular antioxidant system plays an important role in resisting ferroptosis by inhibiting lipid peroxidation. The key pathways of ferroptosis include the amino acid metabolism pathway with SLC7A11-GPX4 as the key molecule, the iron metabolism pathway with ferritin or transferrin as the main component, and the lipid metabolism pathway. The occurrence of ferroptosis is regulated by intracellular proteins, which undergo various post-translational modifications, including ubiquitination. The ubiquitin-proteasome system (UPS) is one of the main degradation systems in cells. It catalyzes the ubiquitin molecule to label the protein and then the proteasome recognizes and degrades the target protein. UPS promotes ferroptosis by promoting the degradation of key ferroptosis molecules (such as SLC7A11, GPX4, and GSH) and antioxidant systems (such as NRF2). UPS can also inhibit ferroptosis by promoting the degradation of related molecules in the lipid metabolism pathway (such as ACLS4 and ALOX15). In this review, we summarize the latest research progress of ubiquitination modification in the regulation of ferroptosis, generalize the published studies on the regulation of ferroptosis by E3 ubiquitin ligase and deubiquitination, and sum up the targets of ubiquitin ligase and deubiquitination regulating ferroptosis, which is helpful to identify new prognostic indicators in human diseases and provide potential therapeutic strategies for these diseases.

OBJECTIVE To establish the HPLC fingerprint of Xintongshu spray, determine the contents of identified components, and investigate the transferring patterns of the index components of decoction pieces, intermediates and spray, so as to provide scientific reference for technology management and quality control of Xintongshu spray. METHODS HPLC fingerprints of 13 batches of Xintongshu spray were established by the Similarity Evaluation System for Chromatographic Fingerprints of TCM (2012 edition), and common peaks were identified; the contents of identified components were determined by HPLC. The paeonol in Moutan Cortex and ferulic acid in Chuanxiong Rhizoma were used as index components to investigate the transferring patterns of them in decoction pieces, intermediates and spray. RESULTS There were a total of 33 common peaks in the fingerprints of 13 batches of Xintongshu spray, and the similarities were more than 0.994. Eight components were identified, i.e. gallic acid (peak 5), oxypaeoniflorin (peak 9), chlorogenic acid(peak 10), caffeic acid (peak 14), paeoniflorin (peak 17), ferulic acid (peak 21), senkyunolide Ⅰ (peak 27) and paeonol (peak 31). The contents of 8 components ranged from 0.590 3- 0.719 7, 0.565 7-0.851 3, 0.279 4-0.368 1, 0.080 6-0.106 1, 1.922 5-3.033 5, 0.151 3-0.191 6, 0.250 6-0.336 0, 3.056 7-4.161 0 mg/mL, respectively. The average transfer rates of paeonol and ferulic acid from decoction pieces to sprays were 63.76% and 38.06%, respectively. It was also found that the process in which the loss of paeonol was more than 30% was the extraction by percolation and negative pressure concentration of Moutan Cortex. The process in which the loss of ferulic acid was more than 50% was the steam distillation extraction process of Chuanxiong Rhizoma. CONCLUSIONS The established HPLC fingerprint and content determination method of Xintongshu spray are reproducible and specific. The key processes that cause a decrease in the average transfer rates of the index components are the extraction by percolation and negative pressure concentration of Moutan Cortex and steam distillation extraction of Chuanxiong Rhizoma.
