Lens injury is an important etiological factor in the reduction of visual function following ocular trauma.Currently, there are no clear standards for the classification of lens injury, and comprehensive diagnostic tools are lacking.This deficiency leads to numerous controversies and challenges in critical areas, such as diagnosis and preoperative evalution, timing of surgery, surgical strategy, and assessment of postoperative prognosis.Tomographic imaging technology, such as computed tomography, magnetic resonance imaging, optical coherence tomography, has introduced a new dimension to the evaluation of lens injury, which is crucial for assessing the transparency, texture, location, morphology, and integrity of the lens, as well as the zonules and nearby intraocular structures.However, the use of tomographic imaging technology is somewhat limited due to the limitations of relying on a single method.With the ongoing advancement of imaging technologies and the rapid development of big data and artificial intelligence, tomographic imaging will become an increasingly essential tool in the future management of lens injury.Our expert group reviewed the epidemiological characteristics and classification of lens injury and the major challenges currently faced in the diagnosis and treatment of lens injury, and provided expert recommendations mainly focusing on the application, shortcomings and limitations of current tomographic imaging technology in the diagnosis and treatment of lens injury, and future development directions.

Objective:To investigate the clinical significance and inducing factors of abnormal intraoperative neurophysiological monitoring (IONM) signals during surgery for cervical degenerative diseases.Methods:A retrospective analysis was performed on 586 patients who underwent cervical degenerative disease surgery with IONM at the Department of Orthopedics, The First Affiliated Hospital of Soochow University, from April 2015 to April 2024. Surgical approaches included 380 anterior spinal canal decompression and fusion procedures, 154 posterior spinal canal decompression and fusion procedures (including single-door laminoplasty, total laminectomy, and hemilaminectomy), and 52 combined anterior-posterior surgeries. The multimodal IONM protocol employed transcranial electrical stimulation motor evoked potentials (TES-MEP) and cortical somatosensory evoked potentials (CSEP), combined with electromyography (EMG). Bilateral deltoid muscles, thenar/hypothenar muscles and abductor hallucis muscles were monitored in all patients. Intraoperative MEP, SEP, and EMG results were recorded to analyze the causes of abnormal signals, intraoperative response strategies, and postoperative neurological function and outcomes. Fourfold table chi-square tests were used to analyze factors possibly associated with IONM alerts.Results:Among the 586 cervical surgeries, 17 cases (2.9%) exhibited abnormal IONM signals. These included 4 cases of anterior cervical discectomy and fusion (ACDF), 4 cases of anterior cervical corpectomy and fusion (ACCF), and 2 cases of combined anterior-posterior surgeries for cervical spondylotic myelopathy; and 5 posterior surgeries and 2 anterior ACCF procedures for ossification of the posterior longitudinal ligament (OPLL). The rate of abnormal IONM signals was significantly higher in patients with maximum spinal cord compression (MSCC)>60% (5.8%, 12/208) than in those with MSCC≤60% (χ 2=9.417, P=0.002); in patients with intraoperative hypotension during posterior surgery (mean arterial pressure reduction>20% from baseline, cumulative duration>20 min), the abnormal IONM rate was 22.2% (6/27), which was significantly higher than that in patients without intraoperative hypotension (χ 2=33.542, P<0.001); in patients who underwent calcified tissue removal during anterior surgery, the abnormal IONM rate was 9.3% (5/54), which was significantly higher than that in patients without calcified tissue removal (χ 2=13.162, P=0.003). Thus, MSCC>60%, intraoperative hypotension during posterior surgery, and calcified tissue removal during anterior surgery may be inducing factors for abnormal IONM signals. Among the 17 patients with monitoring abnormalities, 8 cases showed no significant improvement after corresponding intraoperative treatments, and 7 of these 8 cases experienced varying degrees of muscle strength decline and sensory numbness immediately after surgery; 9 cases showed partial or complete recovery of signals, among which 8 cases had no new-onset neurological impairment after surgery, and 1 case developed unilateral upper limb grip strength decline. IONM demonstrated a sensitivity of 0.8750 and specificity of 0.8889. Conclusions:Multimodal IONM can detect electrophysiological abnormalities of spinal cord nerve function during cervical degenerative disease surgery, providing real-time warning of potential nerve damage during the operation. The proportion of abnormal IONM signals is relatively high in cases with MSCC>60%, intraoperative hypotension during posterior cervical surgery, or calcified tissue removal during anterior cervical surgery.

OBJECTIVE To investigate the effect and potential mechanism of Ziyin Mingmu Formula in treating age-related mac-ular degeneration(AMD)by combining network pharmacology with animal model validation.METHODS Active ingredients of Ziyin Mingmu Formula were obtained from the TCMSP and BATMAN databases,and their targets were searched using the PharmMapper da-tabase.AMD disease targets were identified using the GeneCards,DrugBank,OMIM,and TTD databases.Venny analysis was per-formed to identify the intersection of active ingredient and disease targets.A protein-protein interaction(PPI)network was constructed using the String database,and core targets were screened using Cytoscape 3.9.0 software.KEGG pathway enrichment analysis was per-formed using the DAVID database.Molecular docking of key active ingredients with core targets was performed using Autodock software.A laser-induced mouse choroidal neovascularization(CNV)model was used.Optical coherence tomography angiography(OCTA)was used to assess CNV area in vivo,immunofluorescence staining was used to assess CNV area on choroidal flat mounts,and Western blot analysis was used to examine the expression of proteins involved in the vascular endothelial growth factor(VEGF)pathway.RESULTS Network pharmacology analysis identified 221 active ingredients in the Ziyin Mingmu Formula.PPI analysis i-dentified 29 core targets,including SRC,protein kinase B(AKT1),mitogen-activated protein kinase 1(MAPK1),and heat shock protein 90α family class A member 1(HSP90AA1).KEGG analysis revealed that the VEGF signaling pathway was the most highly en-riched.Molecular docking revealed that the core targets SRC,AKT1,MAPK1,and HSP90AA1 had good binding affinity with the main active ingredients,diosmetin,catechin,vestitol,and licochalcone A.Animal experiments showed that the Ziyin Mingmu Formula significantly reduced CNV area in model mice,downregulated VEGF protein expression,decreased VEGFR2,p38,and ERK1/2 pro-tein phosphorylation levels,and inhibited the VEGF signaling pathway.CONCLUSION Ziyin Mingmu Formula may inhibit CNV for-mation by regulating the VEGF signaling pathway.

Objective To establish the judgment basis of ventilation pipe status by 0 daPa wideband acoustic immittance(WAI-0 daPa),and to assist doctors to determine the status of ventilation tube and determine the timing of extubation.Methods A total of 43 children with 62 ears aged 3-6 years old were tested by 0 daPa broadband acoustic reactance test.The normal middle ear function group were ten children with 20 ears.Children with secreto-ry otitis media more than 12 months after tympanic tube catheterization were divided into 11 cases 19 ears of clear ventilation tube group,and 23 ears in 22 cases of ventilation tube blockage group.A total of 107 frequencies of WAI-0 daPa were obtained.The Kruskal-Wallis H and Nemenyi were used to analyze the influence of ventilation tube status on WAI-0 daPa.Results The WAI-0 daPa at 226-667 Hz was significantly higher in the clear ventila-tion tubegroupthan in the normal middle ear group.The WAI-0 daPa at 226-500 Hz was significantly lower in the blocked ventilation tube group than in the clear ventilation tube group.The WAI-0 daPa at 2 000-3 364 Hz and 6 727 Hz in the normal middle ear function group were significantly higher than those in the blocked ventilation tube group.The WAI-0 daPa in low frequencies was less than 20％,the possibility of blackage of eardrum tube was greater.Conclusion The absorptivity in low frequency region of WAI-0 daPa can be used to determine the status of tympanic catheter ventilation tube and assist doctors to determine the timing of extubation.

Objective:To understand the basic situation of occupational internal exposure to 131I among nuclear medicine staff in Jiangsu province, and to analyze the relevant factors that contribute to the formation of internal exposure. Methods:A four-year external direct measurement of thyroid organ counting was conducted on nuclear medicine staff who underwent 131I treatment in Jiangsu province. The result were statistically analyzed, and the effective dose of accumulated internal exposure was estimated. The relationship between the detection rate of internal exposure and 10 possible factors was analyzed. Results:A total of 847 person-times were monitored during the monitoring period, of which 345 person-times were detected for 131I, with a detection rate of 40.7%. The highest individual monitoring result for internal exposure was 24.83 kBq, with an average value of 77.3 Bq and a median of 28.3 Bq among the detected individuals. The average committed effective dose of internal exposure for staff was 0.201 mSv, with a median of 0.074 mSv among the detected individuals. Conclusions:There is statistically significant difference in the detection rate of individual doses of internal exposure among nuclear medicine staff in each year. It has been observed that the main factors related to the detection rate are age, hospital grade, job position, location, whether there is an automatic dispensing operation, operating method, exposure level and length of exposure. Sufficient attention should be given to the situation of internal exposure, and further effective monitoring should be conducted on all such staff members.

Breast cancer is the leading cause of cancer-related mortality among women worldwide and has drawn extensive research attention.Owing to its molecular heterogeneity,drug resistance,and low therapeutic response,single-modality treatments often fail to achieve satisfactory efficacy or broad applicability.Combination therapy,designed based on the pathophysiological characteristics,related signaling pathways,and biomarkers of breast cancer,has emerged as a promising approach for improving therapeutic outcomes.With the advancement of research on combination strategies,the understanding of their molecular mechanisms—particularly key signaling pathways and biomarkers—has become increasingly important.However,comprehensive reviews addressing these molecular mechanisms and synergistic strategies remain scarce.This article summarizes recent advances in combination therapy for breast cancer,providing a comprehensive review of recent combination therapies for breast cancer and their underlying molecular mechanisms,and focusing on key signaling pathways involved in combination therapy and synergistic strategies,thereby providing theoretical insights and reference for researchers,graduate students,and clinicians engaged in the development of novel combination therapeutic strategies for breast cancer and related malignancies.

Objective To explore the clinical effect of applying an improved"outside-in"technique in hip arthroscopic surgery.Methods Totally 136 patients undergoing hip arthroscopic surgery between June 2021 and July 2023 were selected and studied retrospectively.According to their different surgi-cal approach,they were divided into a modified approach group(n=75,including 30 males and 45 fe-males,with an average age of 36±14)and a classic approach group(n=61,including 33 males and 28 females,with an average age of 31±11).Before as well as 4 weeks,3 months and 6 months after the surgery,both groups were evaluated using the visual analog scale(VAS)and Harris hip score,and observed their surgical complications.Moreover,the surgical outcomes and time of sur-gical approach establishment were compared between the two groups.Results There was no significant difference between the two groups in general information,preoperative VAS and Harris scores.More-over,no significant difference was found between the two groups in the Harris score after surgery.Compared with the classic approach group,the improved group had significantly less surgical time(49.0±16.9 min vs.66.0±13.3 min,P<0.05),without using the C-arm fluoroscopy during surgery.Moreover,in the modified approach group,the time for establishing the mid-anteriorapproach was sig-nificantly shortened(10.4±5.9 min vs.25.9±15.1 min,P<0.05),along with the traction time during surgery(66.0±13.3 min vs.49.0±16.9 min,P<0.05).Conclusion The modified"outside-in"hip ar-throscopy technique is a safe and effective surgical method,easier to operate,with shorter surgical time.

Aim To investigate the impact of G pro-tein-coupled estrogen receptor 1(GPER1),also known as GPR30 playing a significant role in the nerv-ous system,on neuronal damage and cognitive dysfunc-tion following epileptic seizures.Methods The pro-tein expression levels of GPER1 and the DNA damage marker γ-H2AX in epileptic rats were assessed using Western blot.The hippocampal neuronal damage and apoptosis in pilocarpine-induced epilepsy models were evaluated using Nissl and TUNEL staining techniques,compared with GPER1 knockdown(GPER1-KD)rats with wild-type(WT)controls.The behavioral activi-ties,including memory and spatial learning,were mo-nitored during the chronic phase of epilepsy using the IntelliCage system.Results Compared to the control group,GPER1 protein expression in the cerebral cortex and hippocampus significantly increased 24 hours post-epilepsy onset.In the GPER1-KD+EP group,hipp-ocampal neuronal damage was more severe,with a sig-nificant increase in apoptotic neurons compared to the WT+EP group.The IntelliCage data revealed that during free exploration,nose contact,position learn-ing,and reverse position learning stages in the GPER1-KD+EP group exhibited fewer visits and a higher error rate than in the WT+EP group.Conclu-sions Deficiency in GPER1 impairs memory and spa-tial learning abilities following epilepsy,potentially due to exacerbated neuronal injury,apoptosis,and inflam-mation.GPER1 represents a promising therapeutic tar-get for mitigating post-epileptic nerve damage and cog-nitive impairment.

Objective To retrospectively analyze the clinical risk factors and prognosis of perioperative myocardial injury(MINS)in non-cardiac surgery patients admitted to the intensive care unit(ICU).Methods A total of 478 postoperative patients admitted to the Department of Intensive Medicine,Minhang Hospital,Fudan University from Jan 2020 to Dec 2023 were selected.They were divided into MINS group(n=302)and normal group(n=176)based on whether myocardial injury occurred within 7 days after surgery.The differences in clinical characteristics between the two groups were compared,and risk factors for perioperative myocardial injury were identified.Risk factors for mortality in the MINS group were analyzed with 30-day mortality as the clinical endpoint.Results The prevalence of acute physiology and chronic health evaluation Ⅱ(Apache Ⅱ)score,coronary artery disease,and chronic kidney disease were all higher in the MINS group than those in the normal group,with statistically significant differences(P<0.05).The proportion of emergency surgeries,co-infection,and perioperative hypotension were significantly different between the MINS group and the normal group(P<0.05).Multivariate logistic regression analysis revealed that chronic kidney disease,emergency surgery,co-infection,and intraoperative and postoperative hypotension were risk factors for MINS occurrence.Prognostic analysis indicated that perioperative hypotension was a risk factor for 30-day mortality in MINS patients.Conclusion MINS is closely associated with patients'underlying conditions,timing of surgery,and perioperative hypotension status,and especially perioperative hypotension affects the final outcomes.

Objective To explore the relationship between insulin resistance and idiopathic central precocious puberty(ICPP)in girls and the diagnostic value of insulin resistance.Methods Clinical data of 245 girls aged 4 to 7.5 years with low luteinizing hormone(LH)levels(0.2-0.83 IU/L),normal body weight(body mass index standard deviation score between-2 and+2),and early breast development who visited the Department of Pediatric Endocrinology,Henan Provincial Maternal and Child Health Hospital from January 2022 to March 2025 were retrospectively analyzed.According to the Expert Consensus on the Diagnosis and Treatment of Central Precocious Puberty(2022),patients were assigned to an ICPP group(n=123)or a control group(n=122).Correlations between the homeostasis model assessment of insulin resistance(HOMA-IR)and selected indices were assessed.Multivariable logistic regression was used to evaluate the association between HOMA-IR and ICPP,and the diagnostic performance of various indices for ICPP was evaluated.Results HOMA-IR was higher in the ICPP group than in the control group(P<0.001)and was positively correlated with LH peak(rs=0.467,P<0.05)and the LH peak/FSH peak ratio(rs=0.444,P<0.05).The multivariable logistic regression model including age,BMI,and basal LH showed that HOMA-IR was closely associated with ICPP(OR=2.756,95%CI:1.940-3.913).Receiver operating characteristic curve analysis showed that the areas under the curve for basal LH,HOMA-IR,and their combination in diagnosing ICPP were 0.735,0.735,and 0.805,respectively(P<0.05),and the combined model had a greater area under the curve than either basal LH or HOMA-IR alone(both P<0.05).Conclusions HOMA-IR is closely associated with ICPP in girls with low LH and normal body weight,and combining HOMA-IR with basal LH improves early identification and diagnostic efficiency in this population.
