Objective To explore the predictive value of the modified frailty index-11 (mFI-11) for postoperative complications in elderly lung cancer patients undergoing robot-assisted lobectomy. Methods Clinical data were retrospectively collected from lung cancer patients aged ≥65 years who underwent robot-assisted lobectomy at the Department of Thoracic Surgery, Gansu Provincial Hospital, from January 2022 to June 2025. Based on the optimal grouping threshold of 0.27 in previous studies for the mFI-11 score, patients were divided into a frail and a non-frail group. Postoperative complications of the two groups were analyzed, and multivariable logistic regression was used to assess the relationship between mFI-11 and postoperative complications. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive efficiency of mFI-11 for postoperative complications. Results A total of 161 patients were included, with 77 males and 84 females, and an average age of (68.48±2.90) years. Among them, 103 (64.0%) patients were in the non-frail group and 58 (36.0%) in the frail group. Differences between the two groups in terms of independent functional status, hypertension requiring drug control, history of type 2 diabetes, history of chronic obstructive pulmonary disease, American Society of Anesthesiologists classification, and tumor staging were all statistically significant (P<0.05). The length of postoperative hospital stay in the frail group was longer than that in the non-frail group [5.50 (5.00, 8.25) d vs. 5.00 (4.00, 5.00) d, P<0.001]. The incidence rates of general respiratory diseases (25.9% vs. 8.7%), hypoproteinemia (15.5% vs. 4.9%), arrhythmia (12.1% vs. 1.9%), bronchopleural fistula (5.2% vs. 0.0%), transfer to ICU for severe complications (10.3% vs. 1.0%), and readmission within 30 days after discharge (12.1% vs. 1.9%) were all higher in the frail group compared to the non-frail group (P<0.05). Multivariable logistic regression analysis found that mFI-11 had a good predictive efficiency for postoperative complications: general respiratory diseases [area under the curve (AUC)=0.759], hypoproteinemia (AUC=0.723), arrhythmia (AUC=0.795), transfer to ICU for severe complications (AUC=0.713), and readmission within 30 days after discharge (AUC=0.702). Conclusion mFI-11 can effectively predict postoperative complications in elderly lung cancer patients undergoing robot-assisted lobectomy and can serve as an objective indicator for identifying high-risk elderly lung cancer patients.

Objective: To investigate the association between plant-based dietary patterns and gestational weight gain (GWG) among pregnant women with gestational diabetes mellitus (GDM), so as to provide the evidence for guiding the reasonable diet during pregnancy. Methods: GDM pregnant women who participated in the WeBirth project in Hangzhou Obstetrics and Gynecology Hospital were selected. Maternal age and pre-pregnancy body mass index (BMI) were collected. The Chinese version of Pregnancy Physical Activity questionnaire was used to assess the daily activity equivalent. The food frequency questionnaire was used to collect the frequency and amount of food intake in the last month before enrollment. The overall plant-based diet index (PDI), healthy plant-based diet index (HPDI), and unhealthy plant-based diet index (UPDI) were constructed based on food intake and grouped by quartiles. Multiple linear regression models were used to analyze the association between plant-based dietary patterns and GWG. Results: A total of 1 943 pregnant women with GDM, with a median age of 30.91 (interquartile range, 4.92) years. The median BMI of pre-pregnancy was 21.51 (interquartile range, 4.06) kg/m2. The medians of PDI, HPDI and UPDI were 32.42 (interquartile range, 4.60), 32.48 (interquartile range, 4.41) and 32.40 (interquartile range, 5.36), respectively. The median of GWG was 11.30 (interquartile range, 4.52) kg. Multiple linear regression analysis showed that PDI (Q3 group, β=0.674, 95%CI: 0.064-1.285; Q4 group, β=0.702, 95%CI: 0.098-1.306), UPDI (Q3 group, β=1.332, 95%CI: 0.771-1.894; Q4 group, β=1.115, 95%CI: 0.550-1.681) were positively associated with GWG after adjusting for age, pre-pregnancy BMI, daily activity equivalent and daily energy intake. No significant association was found between HPDI and GWG (all P>0.05). Conclusion UPDI was associated with a higher risk of GWG in pregnant women with GDM.

Objective To evaluate the correlation between MRI burden of cerebral small vessel disease and cognitive impairment in elderly hypertensive people.Methods Data of elderly hypertensive people with CSVD at Xingtai People's Hospital Affiliated to Hebei Medical University from January 2018 to September 2024 were analyzed.According to the total MRI burden score,patients were divided into mild to moderate(0-2)and severe(3-4)burden groups.The baseline data and cognitive impairment were compared between groups.The correlation between risk factors of MRI burden and cognitive impairment was analyzed.Results The severe burden group had higher systolic blood pressure[178(155,180)mmHg vs.159.50(147.75,170)mmHg,higher fasting blood glucose[5.70(5.37,5.92)mmHg vs.5.38(4.83,5.70)mmHg,P<0.05]and higher the proportion of cognitive impairment[8(28.1%)vs.3(6.8%),P<0.05]than the mild to moderate group.Multivariate logistic regression analysis revealed that systolic blood pressure(OR=1.033,95%CI:1.001-1.067,P<0.05)was the independent risk factor for total MRI burden.Spearman correlation analysis revealed that MRI total burden was negatively correlated with MMSE score(r=-0.315,P=0.011)and MoCA score(r=-0.662,P<0.001).Compared with the mild to moderate burden group,the severe group performed worse in the areas of orientation,attention and computation,language ability on the MMSE,and worse in visual space and executive ability,attention,language,delayed recall,and orientation on the MoCA(P<0.05).Conclusion Systolic blood pressure is the independent risk factor of MRI total burden in elderly hypertensive people.The higher the total MRI burden,the more severe the cognitive impairment,the worse performance in orientation,visual space and executive ability,attention and computation,language,and delayed recall.

In modern society, sugary foods have become an integral part of many people′s lives. However, excessive sugar consumption has adverse effects on both overall health and oral health, serving as a contributing factor to the global increasing incidence in oral diseases, cardiovascular diseases, cancers, obesity, and diabetes. In response to the health risks related to high-sugar diets, the World Health Organization (WHO) and World Dental Federation (FDI) have proposed initiatives and recommendations, with various governments implementing different policies and strategies to reduce sugar intake. Chinese government has also taken proactive measures. The "Healthy China Action (2019-2030)" initiative introduced by the State Council in 2019 established a crucial benchmark in limiting the average daily intake of added sugar to 25 g per person forward to 2030. Experts from Chinese Center for Disease Control and Prevention and the field of oral health have meticulously examined the impacts of sugar reduction on oral health, as well as strategies, methods, and practical considerations related to reducing sugar intake through several meeting and wrote the "Expert consensus: reducing free-sugar for caries prevention", which was subsequently reviewed and revised based on the feedback from multiple stakeholders. They have conducted thorough analyses of global trends in sugar reduction and best practices to provide valuable insights to China for crafting effective policies and strategies on sugar reduction. This consensus mainly includes the classification of free sugars, the latest scientific evidence on dental caries, recommendations from WHO on sugar-sweetened beverage taxes, nutrition labeling, advertising, food reform, adjusting supply systems, education, and promotion strategies, as well as sugar reduction actions taken by various governments around the world. Combining the actual situation in China, policy recommendations and authoritative popular science knowledge on sugar reduction for caries prevention to public are proposed to advocate for experts in multiple fields to focus on sugar reduction for caries prevention, promote the work process, and provide the scientific basis for oral health educators.

Objective To explore the application value of different deep learning models in predicting the lung cancer spread through air spaces(STAS).Methods A total of 203 patients with stage Ⅰ—Ⅱ primary lung cancer were included,of which 74 were STAS-positive and 129 were STAS-negative.Patients were randomly divided into training set(142 cases)and test set(61 cases)at a 7∶3 ratio.Region of interest(ROI)was outlined using ITK-SNAP software,facilitating the extraction of tumor and peritumoral images.The Resnet18,Inception_v3,and Vision Transformer(Vit)were employed for model training and feature extraction.Feature selection was performed by the least absolute shrinkage and selection operator(LASSO)algorithm and Spearman correlation coefficient,followed by the establishment of a predictive model using the Naive Bayes machine learning algorithm.The receiver operating characteristic(ROC)curve was drawn to compare the prediction performance of each model.The assessment of calibration was performed using calibration curves,and the evaluation of clinical application value was conducted using decision curve analysis(DCA).Results The area under the curve(AUC)for the training and test sets were as follows:the training set Resnet18 0.849-0.930,Inception_v3 0.848-0.888,Vit 0.747-0.842;and the test set Resnet18 0.796-0.846,Inception_v3 0.783-0.804,Vit 0.690-0.796.In tumor-peritumoral images,Resnet18 had a higher calibration and better clinical net benefit,while Vit showed superior calibration and clinical net benefit when only tumor tissue was considered.Conclusion Deep learning models can effectively predict lung cancer STAS,providing more decision support for the preoperative diagnosis and treatment of stages Ⅰ—Ⅱ lung cancer.

Objective To develop Tibetan nasalance test materials,and to determine the normal range of na-salance in Tibetan-speaking children,and to investigate the characteristics of nasalance in Tibetan schoolchildren in different Chinese and Tibetan corpora.Methods Three corpora,including three Chinese test sentences,three Ti-betan test materials,and three Tibetan rhymes,were selected to test the nasalance of 50 children(7～12 years old)in the context of Tibetan as their mother tongue in the Tibetan region during pronunciation.Results Differences in nasalance between Chinese and Tibetan nasal sentences were statistically significant(P＜0.01)and lower in Tibetan than in Chinese among Tibetan schoolchildren.The mean nasalance of Tibetan rhymes showed/i/＞/u/＞/a/.Na-sal sentences of Tibetan corpus,oral sentences,oral-nasal sentences and Tibetan rhyming/i/had statistically signif-icant differences in nasalance between genders(P＜0.05 or P＜0.01).Conclusion When assessing the nasalance of Tibetan schoolchildren with Tibetan,a special dialect of Tibetan,as their mother tongue and main language of com-munication in Tibet,the choice of corpus is one of the important factors influencing the nasalance in addition to age and gender,and the application of the Tibetan corpus provides important reference information for the phonological assessment of Tibetan children with nasal resonance disorders.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Objective To study the syntactic impairment characteristics of wh-question comprehension and expression in Chinese non-fluent aphasic patients.Methods The differences in comprehension and expression be-tween 25 non-fluent aphasic patients and 25 normal subjects were tested in the form of sentence-figure matching and elicitation-repetition to analyze syntactic impairment characteristics related to sentence patterns,question objects,and question words.Results The patients with non-fluent aphasia had impaired comprehension and expression of specific interrogative sentences,and the order of correct comprehension was:(active interrogative sentence,object pseudo-split interrogative sentence)＞(subject pseudo-split interrogative sentence,passive interrogative sentence),and the order of correct expression was:active interrogative sentence＞(pseudo-split interrogative sentence,pas-sive interrogative sentence).Conclusion The pattern of impaired comprehension and expression of wh-question was similar in patients with Chinese non-fluent aphasia.The main influences on syntactic structure included the object of questioning(subject-object)and the type of sentence.Obstacles were more pronounced in sentences with wh-move-ment and non-canonical order.

Objective To investigate the effect of percutaneous balloon compression on the ocular surface in the treatment of trigeminal neuralgia (TN). Methods A total of 30 patients (60 eyes) diagnosed with TN who underwent parallel balloon compression surgery from May 2023 to June 2024 were included in the study. Corneal sensation,Schirmer Ⅰ test results,tear film break-up time (TBUT),and corneal fluorescein staining scores were evaluated in both eyes one day before and one day after the surgery. Results The tear secretion values and TBUT in both eyes of TN patients were lower than normal. Preoperatively,there were no statistically significant differences in various ocular examinations between the two eyes (P=0.144,P=0.072,P=0.069,P=1.000). One day postop-eratively,the corneal sensitivity,tear secretion value,and TBUT of the affected eye were significantly lower com-pared to the contralateral eye (P<0.01,P<0.01,P<0.01),while the fluorescein staining score showed a slight increase but was not statistically significant (P=0.157). Compared to preoperative levels,the postoperative corneal sensitivity,tear secretion value,and TBUT of the affected side were significantly reduced (P<0.01,P<0.01,P<0.01),while the fluorescein staining score showed a slight increase but remained non-significant (P=0.157). Conclusions TN patients patients exhibit reduced bilateral tear secretion and compromised tear film stability. Following balloon compression surgery,the corneal sensitivity of the affected eye diminishes,leading to a further decline in tear secretion and tear film stability. Consequently,it is imperative that TN patients receive ophthalmic intervention,treatment,and regular follow-up,irrespective of whether they undergo surgery.

Objective To investigate the correlation between voice fatigue index(VFI)and the subjective and objective assessment results of voice impairment.Methods Fifty-one patients with voice disorders and 48 normal subjects were selected for VFI assessment and comparison of the differences in scores between the two groups.Sub-jective voice handicap index(VHI)and objective acoustic assessment were performed on the patients with voice dis-orders to analyze the correlation between VFI scores and the results of subjective and objective assessment of voice disorders.Results There was significant difference of the VFI scores between the voice disorder patients and the control group,with the total VFI score,part Ⅰ and part Ⅱ scores higher than those of control group,and the partⅢ score lower than those of the control group(P＜0.05),and there was a strong correlation between the total and part VFI scores and the total and part VHI scores(P＜0.05 or P＜0.01).The VFI part Ⅰ and part Ⅱ scores were regatively correlated with the I-low(P＜0.05),but there was not a significant correlation with the other acoustics parameters and the dysphonia severity index(DSI)(P＞0.05).Conclusion Voice fatigue symptoms were more prominent in the voice-impaired population,and the VFI score was significantly correlated with the subjective voice disorder severity,but the correlation with the objective acoustic parameters was not significant.
