Historically,most vitreoretinal surgeons have considered the single operation anatomical reattachment rate of the retina following rhegmatogenous retinal detachment(RRD)repair as the primary outcome measure.Nevertheless,even with successful anatomical retinal reattachment,many patients still experience visual function defects such as metamorphopsia and aniseikonia.Retinal displacement is one of the primary contributing factors.Accumulating evidence suggests that postoperative visual function and vision related quality of life are of greater clinical importance to patients.PubMed and Web of Science database were searched for studies published before November 2025 on “retinal displacement”and“rhegmatogenous retinal detachment”.This paper systematically reviews the research advances in retinal displacement after RRD repair, as well as its detection modalities,pathogenesis,risk factors,and functional prognosis.

BACKGROUND: Molecular subtyping is an essential complementarity after pathological analyses for targeted therapy. This study aimed to investigate the consistency of next-generation sequencing (NGS) results between circulating tumor DNA (ctDNA)-based and tissue-based in non-small cell lung cancer (NSCLC) and identify the patient characteristics that favor ctDNA testing. METHODS: Patients who diagnosed with NSCLC and received both ctDNA- and cancer tissue-based NGS before surgery or systemic treatment in Lung Cancer Center, Sichuan University West China Hospital between December 2017 and August 2022 were enrolled. A 425-cancer panel with a HiSeq 4000 NGS platform was used for NGS. The unweighted Cohen's kappa coefficient was employed to discriminate the high-concordance group from the low-concordance group with a cutoff value of 0.6. Six machine learning models were used to identify patient characteristics that relate to high concordance between ctDNA-based and tissue-based NGS. RESULTS: A total of 85 patients were enrolled, of which 22.4% (19/85) had stage III disease and 56.5% (48/85) had stage IV disease. Forty-four patients (51.8%) showed consistent gene mutation types between ctDNA-based and tissue-based NGS, while one patient (1.2%) tested negative in both approaches. Patients with advanced diseases and metastases to other organs would be suitable for the ctDNA-based NGS, and the generalized linear model showed that T stage, M stage, and tumor mutation burden were the critical discriminators to predict the consistency of results between ctDNA-based and tissue-based NGS. CONCLUSION ctDNA-based NGS showed comparable detection performance in the targeted gene mutations compared with tissue-based NGS, and it could be considered in advanced or metastatic NSCLC.

Objective: To investigate morphological differences between obstructive and non-obstructive coronary artery disease (CAD) patients using computer-aided image analysis, and identify color and texture features for traditional Chinese medicine (TCM) syndrome differentiation. Methods: This prospective study enrolled patients undergoing coronary computed tomography angiography (CTA) at the Affiliated Hospital of Liaoning University of Traditional Chinese Medicine between May 1, 2024 and August 7, 2025. Based on CTA results, patients were categorized into obstructive CAD and non-obstructive CAD groups. Standardized tongue images were acquired using a dedicated mobile application (Traditional Chinese Medicine Tongue Image-Assisted Diagnosis System) and analyzed for the overall tongue surface and three macroscopic features (tooth marks, fissures, and red dots) from which high-dimensional color and texture parameters were extracted. Multi-scale texture features were derived using spatial-domain Laplacian pyramid and frequency-domain wavelet transform methods. Dimensionality reduction and feature selection were performed using principal component analysis (PCA) and random forest with 5-fold cross-validation. Feature stability was assessed using Hodges-Lehmann estimator and Cliff’s δ. A multi-view XGBoost model was developed to differentiate the two groups and evaluated on a temporally independent validation set using accuracy and the area under the receiver operating characteristic curve (AUC). SHapley Additive exPlanations (SHAP) analysis was applied to interpret model decisions. Results: This study analyzed 373 CAD patients, including 167 with obstructive CAD and 206 with non-obstructive CAD according to CTA results. The whole cohort was divided into training set (n = 316, obstructive : non-obstructive = 142 : 174 ) and validation set (n = 57, obstructive : non-obstructive = 25 : 32), with balanced baseline characteristics (P > 0.05). Macroscopic tongue analysis revealed that patients with obstructive CAD had fewer tooth marks [odds ratio (OR) = 0.43, P < 0.05] and red dots (OR = 0.46, P < 0.05). High-dimensional color analysis identified pronounced intergroup differences, most notably a reduction in hue values in the hue-saturation-intensity (HSI) color space among obstructive CAD patients (Cliff’s δ = – 0.31, P = 2.72 × 10–6; Hodges-Lehmann estimator: – 0.31). PCA results suggested that tongue surface features explained the highest proportion of variance (48.2%). Random forest screening identified 77 stable features across all tongue regions, with wavelet-transformed texture features demonstrating the highest importance. The multi-view XGBoost fusion model achieved an accuracy of 75% and an AUC of 0.779 in the independent validation set. SHAP analysis identified the wavelet-based feature—left-handed lower-level gray-level size zone matrix zone variance (LHL_glszm_ZoneVariance) as the top predictor, accounting for 40.6% of the model's decision variance, and indicated that 85.3% of the predictive power came from wavelet-based texture features. Conclusion This study has provided objective evidence for the TCM concept that “the tongue reflects the heart” by identifying distinct morphological and colorimetric tongue patterns in patients with obstructive CAD through artificial intelligence (AI)-driven image analysis, and the promising performance of the computational model suggests its potential as a non-invasive adjunctive tool for CAD assessment.

Precancerous lesions of gastric cancer （PLGC） are a group of pathological changes caused by abnormalities in the structure， morphology， and differentiation of gastric mucosal epithelial cells. Since the early symptoms are hidden and non-specific， PLGC is not easy to be diagnosed and it has often developed into intermediate or advanced gastric cancer once being diagnosed and missed the best time for treatment. Accordingly， the incidence of this disease is increasing year by year， which lifts a heavy burden on the patients. The pathogenesis of PLGC is complex， involving inflammatory microenvironment， bile reflux， glycolysis， autophagy， and apoptosis. Currently， PLGC is mainly treated with anti-inflammatory and endoscopic therapies， which are difficult to curb the development of PLGC. Therefore， seeking a safe and effective therapy is an important topic of modern research. Traditional Chinese medicine （TCM）， characterized by treatment based on syndrome differentiation and a holistic view， exerts effects via multiple pathways， mechanisms， and targets. Recent studies have confirmed that TCM can regulate the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR）， Wnt/β-catenin， Sonic Hedgehog， nuclear factor-κB （NF-κB）， Janus kinase/signal transducer and activator of transcription （JAK/STAT）， hypoxia-inducible factor-1α （HIF-1α）， neurogenic locus notch homolog protein （Notch）， nuclear factor E₂-related factor 2 （Nrf2） and other signaling pathways. By targeting these pathways， TCM can inhibit aerobic glycolysis， reduce oxidative stress， repair the inflammatory microenvironment， regulate cellular autophagy， and promote vascular normalization， thereby delaying or reversing PLGC. However， few researchers have systematically summarized the TCM regulation of PLGC-associated pathways. By reviewing the relevant articles at home and abroad， this paper summarized the roles of the above signaling pathways in the development of PLGC and the research progress in the regulation of signaling pathways by TCM in the treatment of PLGC， with a view to providing a new theoretical basis for the clinical research on PLGC and the drug development for this disease.

Lipoatrophic diabetes(LD) is a rare and distinct form of diabetes characterized by notable clinical heterogeneity. It is often considered one of the manifestations of lipodystrophy syndrome(LDS). In clinical practice, LD is frequently misdiagnosed as type 2 diabetes; however, its management protocols and prognostic outcomes differ significantly from those of other diabetes subtypes. Therefore, timely and accurate diagnosis is of great clinical importance. This paper presents two detailed case reports of female patients with LD. Through an in-depth analysis of their clinical features, it also provides an comprehensive review of the key clinical manifestations of LDS, potential pathogenic mechanisms, and current approaches to genetic diagnosis. The aim is to enhance clinicans′ awareness of LDS and improve corresponding diagnostic and therapeutic strategies.

Objective:To revise the quality standards of purified siliceous earth in the Chinese Pharmacopoeia 2020 Vol Ⅳ.Methods:Referring to USP2024 and GB 14936-2012 food additive purified siliceous earth and related ref-erences,the current quality standards for pharmaceutical excipient purified siliceous earth were revised,including description,dissolved substances in water,dissolved substances in acid,and content determination.The soluble a-luminum content was also investigated.Results:Revised the description of characteristic items,methods for deter-mining dissolved substances in water and acid,and limits for content determination;Through the investigation of soluble aluminum before and after filtration of human serum albumin(HSA)samples using purified siliceous earth as a filter aid,it is shown that purified siliceous earth has a certain degree of adsorption effect on aluminum ele-ment.At present,the use of low-temperature ethanol ultrafiltration process does not increase the residual aluminum content in biological products,so an aluminum element determination item is not added to the standard.Conclusion:The comprehensive quality standards for purified siliceous earth will be included in the Chinese Phar-macopoeia 2025 edition,providing strong technical support for the quality and safety supervision of this product.

Objective:To evaluate the effect of esketamine on the quality of postoperative sleep in preschool children undergoing day surgery.Methods:This was a prospective randomized controlled study. One hundred and four preschool children of either sex, aged 4-7 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, underwent elective day surgery for strabismus correction under general anesthesia at the First Affiliated Hospital of Zhengzhou University from July to September 2024, were selected. The preschool children were divided into 2 groups ( n=52 each) by the random number table method: control group (group C) and esketamine group (group S). In group S, additional esketamine 0.25 mg/kg was intravenously injected during anesthesia induction. The sleep quality scores were evaluated using the Children′s Sleep Habit Questionnaire by the guardians on the night before surgery, the 1st night after surgery, the 3rd night after surgery and the 7th night after surgery, and development of postoperative sleep disorders (the Children′s Sleep Habit Questionnaire score >41) was recorded. The FLACC pain scores and usage rate of flurbiprofen axetil were recorded immediately before leaving the postanesthesia care unit (PACU) and on days 1, 3 and 7 after surgery. The time of laryngeal mask airway removal, length of stay in PACU and development of adverse reactions such as increased oral secretions, agitation, nausea and delirium within 48 h after surgery were recorded. Results:Compared with group C, the Children′s Sleep Habits Questionnaire score and incidence of postopoerative sleep disorders were significantly decreased on the 1st night after surgery, the FLACC pain scores were decreased immediately before discharge from the PACU and at 1 day after surgery, the usage rate of flurbiprofen axetil was decreased ( P<0.05), and no significant change was found in the time of laryngeal mask airway removal, length of stay in PACU and incidence of postoperative adverse reactions in group S ( P>0.05). Conclusions:Anesthesia induction with esketamine 0.25 mg/kg can improve the quality of postoperative sleep in preschool children undergoing day surgery.

Objective To analyze the characteristics of acupoint selection in treatment for func-tional constipation.Methods Clinical literature on acupuncture and electroacupuncture therapy for functional constipation from January 1,2013,to December 31,2023,was retrieved from CNKI.The acupuncture prescriptions were collected and organized,and data mining techniques were employed to analyze the patterns of acupoint selection.Results A total of 182 articles were included,yielding 123 acupuncture prescriptions involving 92 acupoints with usage frequency of 967 times.The top 10 acu-points in frequency were Tianshu(158 times),Shangjuxu(138 times),Dachangshu(61 times),Zu-sanli(60 times),Zhigou(57 times),Fujie(57 times),Guanyuan(35 times),Zhongwan(34 times),Qihai(34 times),and Quchi(28 times).The meridians of the selected acupoints for acu-puncture treatment of functional constipation were mainly involved in stomach,bladder,Ren,and spleen meridians.Association rule analysis revealed that the combination of Tianshu-Shangjuxu had the highest occurrence probability(75.82％),followed by Tianshu-Dachangshu(33.52％)and Tianshu-Zusanli(32.97％).Cluster analysis of acupoints showed that the main acupoints selected for acu-puncture treatment of functional constipation could be divided into 10 clusters,including primary acu-points,acupoints for various syndrome types,acupoints for regulating spirit,and acupoints for regula-ting sympathetic nerves.Conclusion Acupuncture treatment for functional constipation should follow the principles of holistic treatment and syndrome differentiation,combined with the methods of selecting acupoints based on their upper-lower,proximal-distal,and anterior-posterior relationships.The acu-point selection patterns identified in this study can provide important references for clinical treatment of functional constipation,offer guidance for practitioners in acupoint selection,facilitate precise treatment,and promote early patient recovery.
