ObjectiveTo observe the activation patterns and functional connectivity in the prefrontal cortex of patients with post-stroke anxiety (PSA) using functional near-infrared spectroscopy, in order to explore the underlying neural mechanism. MethodsFrom December, 2024 to September, 2025, 120 stroke patients were selected in Changzhou De'an Hospital. They were divided into PSA group (n = 60) and non-PSA group (n = 60) according to the score of Hamilton Anxiety Scale (HAMA). All patients wore an 18-channel fNIRS acquisition cap for detection. The differences in resting-state functional connectivity between the frontopolar cortex (FPC) and dorsolateral prefrontal cortex (DLPFC) were examined in both groups, as well as task-related activation in these brain regions. ResultsResting-state functional connectivity analysis revealed no statistically significant difference in network connectivity between two groups in the FPC and DLPFC regions (|t| < 1.301, P > 0.05). Task-related activation results revealed significantly reduced activation in the contralateral FPC of PSA group compared to the non-PSA group (Z = -2.063, P < 0.05). Activation levels in this region showed a negative correlation with the scores of HAMA (ρ = -0.201, P = 0.028). ConclusionActivation decreased in the contralateral frontal pole during the task state for patients with PSA, and the activation levels negatively correlates with anxiety severities.

Objective: To investigate the emotional and behavioral problems among preschool children and the correlations with maternal parenting competence and family rearing environment, so as to provide a scientific basis and practical guidance for the physical and mental health development of preschool children. Methods: In June 2025, 660 preschool children aged 3-6 years old were selected from 10 kindergartens in Hefei, Anqing, and Tongling in Anhui Province by using a stratified cluster random sampling method. A questionnaire survey was conducted among all parents of preschool children using the Parent version of the Strengths and Difficulties Questionnaire, the Child Family Rearing Environment Scale, and the Chinese version of the Parenting Sense of Competence Scale. Pearson correlation analysis and multiple linear regression analysis were used to analyze the related factors of emotional and behavioral problems among preschool children. SPSS macro program Process 4.1 and Bootstrap method were used to test the mediating effect of family parenting environment between emotional and behavioral problems among preschool children and maternal parenting competence. Results: The detection rate of emotional and behavioral problems among preschool children was 20.15%. The total scores of family rearing environment and maternal parenting competence were negatively correlated with emotional and behavioral problems among preschool children ( r =-0.45,-0.79), and the total score of family rearing environment was positively correlated with the total score of maternal parenting competence ( r =0.43) (all P <0.01). Multiple linear regression showed that, after controlling whether being only child, parents educational level, registered residence location and other variables, family rearing environment, self efficacy and satisfaction were all negative predictors of emotional and behavioral problems among preschool children ( B =-0.07, -0.42, -0.42, all P <0.01). The mediation effect results showed that maternal parenting competence could positively predict the family rearing environment ( B =0.75), while maternal parenting competence and family rearing environment could both negatively predict emotional and behavioral problems among preschool children ( B =-0.49, -0.06 ) (all P <0.05). The Bootstrap sampling method test results showed that the effect value of the indirect effect of maternal parenting competence on emotional and behavioral problems through the family rearing environment was -0.04, and the effect proportion was 8.21 %. Conclusion Preschool children with a better family rearing environment and stronger maternal parenting competence are less likely to have emotional and behavioral problems, among which the family rearing environment has a mediating effect.

Objective To analyze the epidemiological characteristics of statutory infectious diseases in Yichang City from 2015 to 2023 and evaluate the effectiveness of non-pharmaceutical interventions (NPIs) in infectious disease prevention and control, and to provide a basis for formulating prevention and control strategies. Methods Descriptive epidemiological methods were used to analyze annual incidence rates. SARIMA and SARIMA intervention models were constructed to predict the incidence rates of infectious diseases. Interrupted time series analysis (ITS) was applied to assess the control effectiveness. Results The average annual incidence rate from 2015 to 2023 was 787.47/100 000, with the top five diseases being influenza, hand-foot-and-mouth disease, hepatitis B, tuberculosis, and diarrheal diseases. The average incidence rate from 2015 to 2019 (654.31/100 000) was significantly higher than that from 2020 to 2022 (489.01/100 000) (χ²= 3 499.6, P < 0.05). The total incidence rate in 2023 (2 396.51/100 000) was significantly higher than the average annual incidence rates from 2015-2019 (χ²= 108 186.1, P < 0.05) and 2020-2022 (χ²= 112 869.4, P < 0.05). SARIMA model results indicated that the actual incidence rate from 2020 to 2022 decreased by 73.49% compared to the predicted rate without intervention, with the highest decline observed in respiratory infectious diseases (79.57%). The SARIMA-intervention model showed a 55.48% relative decrease in the total incidence rate for 2023, with the largest reduction in respiratory infectious diseases (63.28%) and a slight increase in intestinal infectious diseases (5.48%). Conclusion NPIs effectively reduce the incidence of statutory infectious diseases in the short term, especially for acute respiratory and intestinal infectious diseases. However, long-term effectiveness faces challenges, necessitating the development of differentiated prevention and control strategies.

Despite breakthroughs in immunotherapy for solid tumors, significant variations in treatment efficacy persist. Up to 80% of cancer patients suffer from malnutrition, which leads to: lymphoid atrophy and reduced T-cell reserves; deficiency of substrates required for T-cell activation and expansion; concurrent inflammation hindering T-cell infiltration into tumors; and cachexia accelerating PD-1 antibody clearance. Clinical studies confirm that severe malnutrition significantly impairs immune responses and increases the risk of treatment toxicity. Therefore, implementing standardized nutritional therapy is crucial for optimizing the reserve, activation, expansion, and infiltration capacity of immune cells, thereby providing a sound immune system foundation for immunotherapy. Immunonutrition therapy, by enhancing immunonutrients such as arginine, omega-3 polyunsaturated fatty acids, and nucleotides, reduces the secretion of pro-inflammatory mediators and promotes T-cell activation and proliferation. This enhances anti-tumor immune responses, prolongs survival, and advances cancer treatment towards multimodal combination and precision approaches.

OBJECTIVE To evaluate the efficacy and safety of sacituzumab tirumotecan combined with bevacizumab for the treatment of human epidermal growth factor receptor 2-negative （HER2－） breast cancer with brain metastases.METHODS Clinical data of 90 patients with HER2－ breast cancer with brain metastases treated at the First Affiliated Hospital of Nanyang Medical College from December 2024 to November 2025 were retrospectively collected. According to the treatment regimens， the patients were divided into a control group （ n ＝55） and an experimental group （ n ＝35）. Patients in the experimental group received sacituzumab tirumotecan combined with bevacizumab， whereas those in the control group received conventional systemic therapy， including albumin-bound paclitaxel-based regimens， capecitabine-based regimens， or gemcitabine/vinorelbine combined with platinum-based regimens. Short-term efficacy， progression-free survival （PFS）， brain metastasis-related efficacy， adverse events， treatment discontinuation due to adverse events， and treatment-related deaths were compared between the two groups.RESULTS The objective response rate （ORR）， disease control rate， median PFS， intracranial disease control rate， and proportion of patients with improvement in neurological symptoms in the experimental group were significantly higher than in the control group （ P ＜0.05）. Stratified analysis showed that PFS of the experimental group was significantly longer than the control group among patients with Breast-Graded Prognostic Assessment scores ≥2.0 and ＜2.0 （ P ＜0.05）. There were no statistically significant differences in the proportion of patients with glucocorticoid dose reduction/discontinuation， the incidence of adverse events of different grades， or the rate of treatment discontinuation due to adverse events between the two groups （ P ＞0.05）. No treatment-related deaths occurred in either group.CONCLUSIONS Compared with conventional systemic therapy， sacituzumab tirumotecan combined with bevacizumab can improve the ORR and prolong PFS in patients with HER2－ breast cancer with brain metastases， with an overall manageable safety profile.

ObjectiveTo investigate the clinicopathological features， molecular profile， treatment response， and prognosis of SMARCA4 （BRG-1） and SMARCB1 （INI-1）-deficient undifferentiated tumors of the digestive system， aiming to enhance the understanding of this rare and highly aggressive molecular subtype. MethodsThis study is a single-center retrospective analysis. We included 9 cases of malignant digestive system tumors with loss of BRG-1 expression and 3 cases with loss of INI-1 expression， all pathologically confirmed at Sun Yat-sen University Cancer Center between April 2022 and December 2025. By reviewing clinical data， histological morphology，immunohistochemistry and next-generation sequencing （NGS） results from partial cases， we systematically summarized their clinicopathological and molecular characteristics， treatment strategies， and survival outcomes. Results​ Among the 12 patients， 6 were male and 6 were female， with a median age of 62 （44-70） years. 9 cases exhibited SMARCA4 deficiency， and 3 cases exhibited SMARCB1 deficiency. Tumors originated in the stomach （5 cases）， colon （3 cases）， pancreas （1 case）， with the primary site unknown in 3 cases. The histology predominantly showed undifferentiated carcinoma， with 1 case of poorly differentiated carcinoma. The tumor cells were epithelioid with significant atypia. Epithelial markers （e.g. CKpan） were often lost or markedly decreased， while vimentin could be positive. All 9 cases tested for MMR status were mismatch repair proficient （pMMR）， and the Ki-67 proliferation index was high ［median 80% （60%-90%）］. A discordance was observed between IHC findings and NGS results in the 6 sequenced cases. The NGS profiling revealed frequent co-occurring mutations， including TP53， KRAS， and NRAS， with no germline mutations identified.The median follow-up time was 277 （55-867） days. 9 of the 12 patients presented with stage Ⅳ disease at the time of initial diagnosis. Among 3 newly diagnosed patients without metastasis who received treatment， 2 achieved prolonged recurrence-free survival. Patients with advanced disease at initial diagnosis primarily underwent platinum-based chemotherapy or combination regimens， yet their prognosis was generally poor， with a median overall survival of 60 （45-541） days， ranging from 16 to 867 days. Notably， several patients who received chemotherapy combined with targeted therapy and immunotherapy achieved extended survival. ConclusionSMARCA4/SMARCB1-deficient undifferentiated tumor of the digestive system is a distinct molecular subtype characterized by high aggressiveness and poor prognosis， predominantly affecting middle-aged and elderly individuals. Diagnosis relies on the immunohistochemical loss of BRG-1 or INI-1 proteins. While no standard of care currently exists， treatment often refers to regimens for adenocarcinoma of the primary site. Combined immunotherapy and targeted therapy may offer potential benefits， warranting further validation in large-scale prospective studies.

Multiple acyl-CoA dehydrogenase deficiency (MADD) is a rare inherited metabolic disorder of fatty acid oxidation, with highly heterogeneous clinical manifestations. Late-onset MADD predominantly presenting with myopathic features is easily confused with inflammatory myopathy; early identification and administration of high-dose vitamin B₂ can achieve favorable therapeutic effects. This article reports a MADD patient with main manifestations of exercise intolerance and progressive post-exertion muscle weakness. The case is analyzed by integrating blood and urine metabolic screening results and genetic testing findings, so as to provide a reference for the early diagnosis of this disease.

Objective:To investigate the characteristics of elastic program of excited shear wave of plantar soft tissue of diabetic patients and its correlation with levels of glucose metabolism.Methods:A total of 92 patients with type 2 diabetes who admitted to Cangzhou Hospital of Integrated Traditional Chinese Medicine and Western Medicine during January 2022 and January 2023 were selected as diabetes group,and another 92 patients in the prediabetes stage were included in the prediabetes group.Both groups of patients used excited shear wave with different frequencies(400,450,500,550,and 600 Hz)under elastic technique of shear wave.The velocities of shear waves at the 1st metatarsal head,the 3rd metatarsal head and calcaneus of plantar soft tissue,and the thickness of soft tissue of these patients were assessed.The fasting plasma glucose(FPG),2-hour postprandial glucose(2hPG),and glycosylated hemoglobin(HbA1c)levels of sugar metabolism level of two groups were measured,and the correlations between velocity of shear wave,thickness of soft tissue,and level of glucose metabolism were further analyzed.The occurrence of diabetic foot ulcer in the diabetes group was investigated by using follow-up.The receiver operating characteristic(ROC)curve was adopted to assess the predictive value of the velocity of shear wave,and the thickness of soft tissue for diabetic foot ulcer.Results:The FPG,2hPG and HbA1c of glucose metabolism level in the diabetes group were(6.48±0.48)mmol/L,(9.64±1.31)mmol/L and(6.21±0.15)%,respectively,all of which were higher than those[(8.03±0.62)mmol/L,(12.26±1.25)mmol/L and(7.66±0.42)%]in the prediabetes group,and the differences were statistically significant(t=18.961,18.961,31.185,P<0.05).The thickness level of soft tissue at the first metatarsal head was(10.42±3.11)mm in the diabetes group,which was less than(11.76±3.24)mm in the prediabetes group,with a statistically significant difference(t=2.862,P<0.05).Spearman correlation analysis showed that the velocity of shear wave at 500 Hz frequency had a strongest correlation with FPG and HbA1c(r=0.320,0.256,P<0.05),respectively.In the follow-up for patients of diabetes group,14 cases occurred ulcers and 78 cases did not occur ulcers.The velocities of shear wave of the first metatarsal head of 14 patients with ulcers were higher than those of patients without ulcers at all tested frequencies(400,450,500,550,and 600 Hz).The area under curve(AUC)value of ROC curve,specificity and sensitivity of 500 Hz were respectively 0.775,88.46%,and 78.57%in predicting plantar ulcer of patients with diabetes.Conclusion:The velocity of shear wave of soft tissue at the first metatarsal head is significantly correlated with abnormal glucose metabolism in patients with type 2 diabetes.The velocity of shear wave appeared strongest correlation with FPG and HbA1c at500 Hz frequency,which has higher predictive value for diabetic foot ulcer.
