OBJECTIVE To evaluate the efficacy and safety of immune checkpoint inhibitors （ICIs） combined with neoadjuvant chemotherapy in the treatment of early triple-negative breast cancer （TNBC）. METHODS Randomized controlled trials （RCTs） comparing ICIs combined with neoadjuvant chemotherapy （experimental group） versus neoadjuvant chemotherapy alone （control group） were retrieved from PubMed， Cochrane Library， Embase， Web of Science， CNKI， Wanfang Data， and VIP databases， as well as relevant studies published at oncology academic conferences. The search period was from database inception to June 30， 2025. After literature screening， data extraction， and quality assessment， a meta-analysis was performed by using RevMan 5.4 software. RESULTS A total of 6 RCTs involving 3 786 patients were finally included. The meta-analysis results showed that the experimental group had superior event-free survival [HR＝0.73， 95%CI （0.62， 0.85）， P＜0.000 1]， overall survival [HR＝0.69， 95%CI （0.57， 0.84）， P＝0.000 3]， and pathological complete response （pCR） [OR＝1.57， 95%CI （1.37， 1.80）， P＜0.000 01] compared to the control group. The incidence of ≥grade 3 adverse event （AE）， severe AE （SAE）， and ≥ grade 3 immune-related adverse event （irAE） in the experimental group was significantly higher than that in the control group. There was no statistically significant difference between the two groups in the incidence of any AE or any irAE （P＞0.05）. Subgroup analysis revealed that， regardless of programmed cell death ligand 1 expression status （negative or positive），the pCR in the experimental group was significantly higher than that in the control group （P＜0.05）. Additionally， the pCR of the patients with positive lymph nodes in the experimental group was significantly higher to that in the ontrol group （P＜0.05）. There was no statistically significant difference in pCR between the two groups with negative lymph nodes （P＝0.09）. CONCLUSIONS ICIs combined with neoadjuvant chemotherapy can significantly improve event-free survival and overall survival in patients with TNBC， providing patients with long-term survival benefits. However， the risk of ≥ grade 3 AE， SAE and ≥ grade 3 irAE has increased.

Dry eye disease(DED)is a common ocular surface disorder worldwide, primarily characterized by a loss of homeostasis of the tear film, and frequently associated with meibomian gland dysfunction(MGD), decreased tear film stability, ocular discomfort, and visual impairment. In recent years, factors such as the widespread use of digital devices,the aging population, and environmental changes have contributed to a significant increase in its global prevalence, making it a major public health concern. Red light therapy(RLT), also known as low-level laser therapy(LLLT)or photobiomodulation(PBM), is a non-invasive treatment that utilizes low-energy red or near-infrared light to irradiate tissues. It exerts photobiomodulatory effects to promote cellular repair and functional recovery. This therapy has demonstrated considerable potential in treating various ocular conditions. Its broader clinical application could improve therapeutic outcomes, alleviate patient discomfort and financial burden, and reduce the consumption of healthcare resources, thereby yielding significant socio-economic benefits. This paper systematically reviews the multifaceted mechanisms and application prospects of RLT in managing DED, including its anti-inflammatory effects, improvement of meibomian gland function, promotion of conjunctival goblet cell repair, and alleviation of visual fatigue, aiming to provide a theoretical foundation and practical reference for its clinical adoption.

ObjectiveTo investigate the triglyceride-glucose (TyG) index and the level of serum homocysteine (Hcy) in association with the incidence of stroke in type 2 diabetes mellitus (T2DM) patients. MethodsBased on the chronic disease risk factor surveillance cohort in Pudong New Area, Shanghai, excluding those with stroke in baseline survey, T2DM patients who joined the cohort from January 2016 to October 2020 were selected as the research subjects. During the follow-up period, a total of 318 new-onset ischemic stroke patients were selected as the case group, and a total of 318 individuals matched by gender without stroke were selected as the control group. The Cox proportional hazards regression model was used to adjust for confounding factors and explore the serum TyG index and the Hcy biochemical indicator in association with the risk of stroke. ResultsThe Cox proportional hazards regression results showed that after adjusting for confounding factors, the risk of stroke in T2DM patients with 10 μmol·L⁻¹-¹ and Hcy>15 μmol·L⁻¹ was 1.532 times (95%CI: 1.017‒2.309 times, P=0.041) and 1.738 times (95%CI: 1.119‒2.699 times, P=0.014) higher respectively, compared to T2DM patients with Hcy≤10 μmol·L⁻¹. T2DM patients with TyG>9.074 had 1.396 times higher risk of stroke (95%CI: 1.091‒1.787, P=0.008) compared to those with TyG≤9.074. The study found that urea and α1-antitrypsin (α1-AT) were independent risk factors for the incidence of stroke in T2DM patients. For every unit increase in urea andα1-AT, the risk of stroke in T2DM patients increased by 233.6% (HR=3.336, 95%CI: 1.588‒7.009, P=0.001) and 11.3% (HR=1.113, 95%CI: 1.028‒1.205, P=0.008), respectively. Cumulative risk curves showed that Hcy>10 μmol·L⁻¹ and TyG>9.074 accelerated the time to stroke occurrence in T2DM patients. ConclusionElevated levels of Hcy>10 μmol·L⁻¹ and a higher TyG index are risk factors for stroke in T2DM patients. Effective interventions for Hcy and TyG should be conducted for diabetic patients to reduce the incidence of stroke.

Objective:To analyze the incidence and impact on the auditory prognosis of vertigo/dizziness in sudden sensorineural hearing loss patients with moderately severe hearing loss and above. Methods:Clinical data of patients with unilateral sudden sensorineural hearing loss hospitalized from January 2008 to December 2022, aged 18-60 years, PTA≥50 dB HL, and within 14 days of onset were selected. Based on the clinical records of sudden sensorineural hearing loss patients, we determined whether they were accompanied by vertigo/dizziness. The degree of hearing loss is referenced to the 2021 WHO grading criteria and divided into the moderately severe, severe, profound, and total deafness groups. The SPSS 22.0 software was applied to analyze the difference in the auditory prognosis between sudden sensorineural hearing loss patients with moderately severe hearing loss and above who have dizziness/vertigo and those who do not. Results:A total of 697 patients with moderately severe hearing loss and above were collected, including 382 males and 315 females, with an average age of（40.8±11.0） years. The proportions of sudden sensorineural hearing loss patients with dizziness/vertigo among those with moderately severe to total deafness hearing loss were 18.4%, 35.7%, 47.9%, and 76.4% respectively. Compared to the moderately severe, severe, profound, and total deafness groups, the difference was statistically significant（P<0.001）. The complete recovery rates of sudden sensorineural hearing loss patients with moderately severe to total deafness hearing loss were 28.2%, 25.2%, 18.2%, and 1.9% respectively, and the total effective rates were 72.8%, 83.5%, 86.7%, and 78.0% respectively. There were statistically significant differences in complete recovery rate（P<0.001）, significant efficiency rate（P<0.001）, effective rate（P=0.026）, and no recovery rate（P=0.022） among the moderately severe, severe, profound, and total deafness groups. The differences in complete recovery between sudden sensorineural hearing loss patients with and without vertigo/dizziness were statistically significant in the moderately severe, severe, profound, and total deafness groups（P<0.05）, while the total effective rates were only statistically significant in the profound group compared to those without vertigo/dizziness（P<0.05）. After inpatient treatment, sudden sensorineural hearing loss patients with dizziness/vertigo had statistically significant final hearing thresholds at 4 000 and 8 000 Hz for moderately severe hearing loss patients, 2 000-8 000 Hz for severe hearing loss patients, 500-8 000 Hz for profound hearing loss patients, and 2 000-8 000 Hz for total deafness patients compared to those without dizziness/vertigo（P<0.05）. Conclusion:The higher the degree of hearing loss in patients with moderately severe hearing loss and above, the higher the proportion of accompanied vertigo/dizziness. Patients with vertigo/dizziness have poorer recovery of high-frequency hearing, and the complete recovery rate is significantly lower than the patients without vertigo/dizziness.

There are millions of patients with taxane-induced peripheral neuropathy （TIPN）， and there is no effective treatment or prevention measure in clinical practice. The occurrence of TIPN may be related to the dosage form of paclitaxel drugs， genetic and molecular markers， drug dosage and chemotherapy cycle， patient factors， etc. At present， drugs for treating TIPN mainly include those that inhibit axonal degeneration （such as dosazosin， tamsulosin）， prevent mitochondrial dysfunction （such as glutathione trisulfides， antioxidants α -lipoic acid）， improve calcium imbalance in the internal environment （Shaoyao gancao decoction， N-type voltage-gated calcium channel inhibitor IPPQ）， and inhibit neuroinflammation （such as chemokine inhibitors and selective interleukin-8 receptor inhibitors DF2726A）. Further exploration of drug treatment strategies targeting different induction mechanisms is expected to become a new direction for precise clinical prevention and personalized treatment of TIPN.

Objective To explore the relationship between baseline urinary protein levels and the onset of chronic obstructive pulmonary disease (COPD). Methods A questionnaire survey, blood and urine sample collection, physical examination, and pulmonary function test were conducted among permanent residents over 40 years old in Pudong New Area, Shanghai. The subjects were divided into four groups based on the baseline urine albumin-to-creatinine ratio (ACR) quartiles (0~1.65 mg/g, 1.65~4.89 mg/g, 4.89~10.78 mg/g, and ≥10.78 mg/g). Cox regression analysis was used to explore the relationship between ACR levels and the incidence of COPD in middle-aged and elderly people. Results Among the 3 105 subjects, the median follow-up time was 3.212 years (P25~P75：3.102~3.473). 116 new cases of COPD were observed, with an incidence density of 10.423 per 1000 person-years. The incidence densities for COPD at four ACR levels were 7.922 per 1 000 person-years, 8.300 per 1 000 person-years , 11.419 per 1 000 person-years, and 13.843 per 1 000 person-years, respectively. Cox regression analysis revealed that as the ACR level increased, there was a rising trend in the incidence rate of COPD (χ²=4.396, P=0.036). After adjusting for gender, age, education level, occupational exposure to dust, history of childhood pneumonia, smoking, family history of COPD, central obesity, and hypertension, the risk of developing COPD was 2.499 times higher (95% CI: 1.460~4.276) for ACR levels ≥10.78 mg/g compared to the reference group with a baseline ACR level of 0~1.65 mg/g. Conclusion Elevated ACR levels in middle-aged and elderly population may increase the risk of COPD, and early monitoring of urine protein levels is beneficial for COPD prevention.

ObjectiveTo evaluate the intervention effect of meteorological risk forecasting service on acute onset and medical expenses of chronic obstructive pulmonary disease（COPD） patients， and to provide scientific basis for the establishment of health management model for chronic obstructive pulmonary disease（COPD） patients. MethodsStudy subjects were recruited from chronic obstructive pulmonary patients aged ≥40 in Pudong New Area. Propensity score matching method was used to determine the intervention group and the control group. The control group received regular health education and follow-up management， and the intervention group was provided with meteorological and environmental risk forecasting services through WeChat， mobile phone short message service（SMS）and telephone. Finally， a total of2 589 subjects were included in the analysis， including 1 300 in the intervention group and 1 289 in the control group. General demographic data， past medical history and family history of COPD， COPD related knowledge and practice survey， COPD related symptom assessment， acute onset， health service utilization and medical expenses before and after intervention were collected through questionnaire survey. The differences of acute attack， health service utilization and related medical expenses between the two groups before and after intervention were compared to evaluate the intervention effect. ResultsIn terms of acute attacks， after intervention， the incidence of acute attacks in the intervention group was lower than that before intervention（χ²=52.901， P<0.001）， and the incidence of acute attacks in the groups with different intervention methods was lower than that before intervention （P<0.001）. WeChat had the best effect， decreasing the incidence by 14.4%， followed by mobile phone SMS SMS decreasing by 12.3%. In terms of utilization of health services， the outpatient rate due to acute attack was lower in the intervention group after intervention than that before intervention （χ²=7.129， P=0.008）， and the outpatient rate due to acute attack was lower in the subjects who received the forecast service through mobile phone SMS than that before intervention （χ²=4.675， P<0.001）. In terms of medical expenses， there was no significant difference between control group and intervention group with different intervention methods before intervention （P>0.05）. After intervention， the difference between the control group and the intervention group with different intervention methods was statistically significant （H=11.864， P<0.05）. The results of multiple comparisons showed that compared with the control group， the average annual medical expenses of patients receiving mobile phone SMS and telephone forecasting services after intervention were lower than those of the control group， and the difference was statistically significant （P<0.05）. ConclusionMeteorological risk forecasting service can reduce the acute onset of COPD， reduce the rate of consultation and medical expenses due to acute onset， and provide scientific basis for the basic COPD health management model.

With the high-speed growing demands for biomedical materials, graphene oxide(GO) and its functional derivatives show broad application prospects in the system of drug delivery, tumor therapy and nanobiology. GO has excellent hydrophilicity and easily modified surface properties, due to a large content of oxygen-containing functional groups on the GO surface. Meanwhile, the huge specific surface areas and unique π-electronic structures give GO adhesion and adsorption capacities. By means of π-π stacking, electrostatic interaction, hydrophobic interaction or covalent bonding, therapeutic agents can be effectively combined with GO to construct drug delivery systems. GO plays an important role in transdermal drug delivery systems due to their biocompatibility, antibacterial activity, and pro-wound healing activity. As a novel drug delivery system, GO nanomaterials can achieve targeted drug delivery, accumulate drug concentrations at the focal site, and improve drug delivery efficiency. Utilizing the promoting skin regeneration and wound healing properties of GO, several antibacterial materials and wound dressings are prepared for wound treatment. In addition, the special far-infrared resonance effect and electrothermal effect of GO result in heat and electric transfer. In other words, graphene oxide could control and promote transdermal absorption efficiency upon the stimuli of heat and electric. GO is expected to break through the limitation of low transdermal absorption rates in the transdermal drug delivery systems and achieve the purpose of enhancing the transdermal permeability of target molecules (especially macromolecules): ultimately improving bioavailability in vivo. This paper will introduce the structures, physicochemical properties, and biological activities of graphene oxide, summarize its application in transdermal drug delivery systems such as drug carriers, antibacterial materials, wound dressings and transdermal enhancers, and prospect its application in clinical medicine. We hope to provide new ideas and different point of views for the biomedical research of graphene oxide and derivatives. GO will become a representative biomaterial in the field of precision medicine and play a key role in the diagnosis and treatment of diseases.

Objective:To investigate the value of intratumoral and peritumoral radiomics models based on 18F-FDG PET-CT in predicting epidermal growth factor receptor (EGFR) mutation status in lung adenocarcinoma and interpret peritumoral radiomics features. Methods:This study was a cross-sectional study. Patients with lung adenocarcinoma who underwent 18F-FDG PET-CT at the Third Affiliated Hospital of Soochow University between January 2018 and April 2022 were retrospectively collected and samplied into a training set (309 cases) and a test set (206 cases) in a 6∶4 ratio randomly. Radiomics features were extracted from the intratumoral and peritumoral regions of interest based on PET and CT images, respectively, and the optimal feature sets were selected. Radiomics models were established using the XGBoost algorithm, and radiomics scores (intratumoral CT label, peritumoral CT label, intratumoral PET label, peritumoral PET label) were calculated. Logistic regression analysis was used to construct a clinical model and a combined model (incorporating PET-CT intratumoral and peritumoral radiomics, clinical features, and CT semantic features). The predictive performance of the models was evaluated using receiver operating characteristic curves and the area under the curve (AUC). Unsupervised clustering, Spearman correlation analysis, and visualization methods were used for the interpretability of peritumoral radiomics features. Results:In both the training and test sets, the AUC value of CT peritumoral labels was greater than that of CT intratumoral labels for predicting EGFR mutation status in lung adenocarcinoma (training set: Z=3.84, P<0.001; test set: Z=1.99, P=0.046). In the test set, the AUC value of PET intratumoral labels (0.684) was slightly higher than that of PET peritumoral labels (0.672) for predicting EGFR mutation status, but the difference was not statistically significant ( P>0.05). The combined model had the highest AUC value for predicting EGFR mutation status of lung adenocarcinoma in both the training and test sets and was significantly better than the clinical model (training set: Z=6.52, P<0.001; test set: Z=2.31, P=0.021). Interpretability analysis revealed that CT peritumoral radiomics features were correlated with CT shape features, and there were significant differences in CT peritumoral features between different EGFR mutation statuses. Conclusions:The value of CT peritumoral labels is superior to that of CT intratumoral labels in predicting EGFR mutation status in lung adenocarcinoma. The predictive performance of the model can be improved by combining PET-CT intratumoral and peritumoral radiomics, clinical features, and CT semantic features.

Objective:To explore the interaction between pediatric sleep-disordered breathing（SDB）, the intestinal microbiota, and pediatric non-alcoholic fatty liver disease（NAFLD）. Methods:A total of 63 non-obese children（47 children with SDB in the experimental group and 16 without SDB in the control group） were enrolled in this study. The liver function and degree of SDB were assessed in both groups. High-throughput 16S rRNA sequencing was conducted to detect the composition and functional variations of the intestinal microbiota in the two groups of children. Results:Compared with children in the experimental group, serum ALT and AST levels were higher in the control group. and the relative proteobacteria abundance of intestinal flora increased, and the relative abundance of Bacteroidetes decreased significantly. Function including membrane transport, carbohydrate metabolism and lipid metabolism, were enriched in the intestinal microbiota of children with SDB. Conclusion:The composition and functional annotation of the pediatric liver functional status and gut microbiota were significantly different between the two groups of children with and without SDB. Changes in SDB-associated intestinal bacterial abundance may be related to the pathogenesis of pediatric NAFLD.
