Objective:To systematically evaluate the prevalence of dysphagia after treatment in patients with head and neck cancer.Methods:The Wanfang, CNKI, Web of Science, Embase, and PubMed databases were searched from their inception to May 2025. Two researchers independently performed literature screening, data extraction, and risk of bias assessment. The pooled prevalence and 95% confidence interval (CI) were used as effect measures, with heterogeneity assessed using the I2 statistics. Sensitivity analysis was conducted by a leave-one-out approach, and publication bias was evaluated using Egger's test and funnel plots. Results:A total of 18 studies were included, comprising 2,518 patients with head and neck cancer, of whom 1,303 were diagnosed with dysphagia. The meta-analysis showed that the overall prevalence of dysphagia after treatment was 51.2% (95% CI: 42.2%-60.2%). Subgroup analysis indicated higher prevalence among males (49.8%, 95% CI: 35.6%-64.0%), Asian populations (57.7%, 95% CI: 36.8%-77.2%), tumors of the hypopharynx and larynx (45.7%, 95% CI: 39.3%-52.2%), stage Ⅲ-Ⅳ disease (46.3%, 95% CI: 34.9%-58.0%), patients receiving concurrent chemoradiotherapy (51.0%, 95% CI: 41.5%-60.4%), smokers (53.0%, 95% CI: 35.1%-70.6%), studies published in 2020 or earlier (51.9%, 95% CI: 38.3%-65.4%), high-quality studies (66.5%, 95% CI: 45.1%-84.9%), and patients with a post-treatment interval ≤6 months (60.7%, 95% CI: 41.8%-78.1%) (all P<0.001). Conclusions:The prevalence of dysphagia after treatment in patients with head and neck cancer is high, with significant variations related to gender, tumor site, disease stage, geographic region, treatment modality, smoking status, publication year, study quality, and post-treatment interval. Early screening and timely intervention are recommended to improve the quality of life of patients with head and neck cancer.

Hyperglycemia is a primary biological characteristic of diabetes.It is well known that three key indicators are commonly used in clinical practice to measure plasma glucose levels,such as 2-hour postload glucose(2hPG),fasting plasma glucose(FPG),and glycated hemoglobin(HbA1c).However,the association between these indicators and breast cancer incidence remains unclear.This paper systematically reviews the relationship between plasma glucose levels and breast cancer based on the above three indicators,to provide a reference for the formulation of effective plasma glucose management strategies for the primary prevention of breast cancer.

The relationship between the duration of type 2 diabetes mellitus (T2DM) and the risk of female reproductive malignancies is complex and multifaceted. Large population cohort studies revealed a negative association between the duration of T2DM and the incidence of breast cancer and endometrial cancer. Furthermore, the risk of breast and endometrial cancer is the highest within a short time after T2DM diagnosis and remains remarkably higher in patients with longer diabetes duration than in the nondiabetic population. This phenomenon suggests causal reverse bias and potential detection bias. Nevertheless, T2DM remains an important risk factor for breast and

ObjectiveTo investigate the effects of Linggui Zhugantang on mitochondrial fission and fusion and silencing information regulator 3(Sirt3)/adenosine monophosphate dependent protein kinase (AMPK) signaling pathway in chronic heart failure (CHF) rats after myocardial infarction (MI). MethodSD rats randomly divide into sham operation group (normal saline ,thread only without ligature), model group (normal saline, ligation of the left anterior descending coronary artery proximal to the heart), Linggui Zhugantang group (4.8 g·kg-1) and Captopril group (0.002 57 g·kg-1), with 10 rats in each group. Administere drug continuously for 28 days. Echocardiography detected cardiac function parameters. Hematoxylin eosin (HE) staining observed the pathological changes of the heart. Immunofluorescence detected the levels of reactive oxygen species (ROS). JC-1 detect mitochondrial membrane potential. Colorimetry measure adenosine triphosphate (ATP), superoxide dismutase (SOD), malondialdehyde (MDA), mitochondrial respiratory chain complex activity (Ⅰ-Ⅳ). TdT-mediated dUTP nick end labeling (TUNEL) staining detected the apoptosis rate of myocardial tissue. Western blot detected protein expression levels of Sirt3, phosphorylated AMPK (p-AMPK), phosphorylated dynamic-related protein 1(p-Drp1), mitochondrial fission protein 1(Fis1), mitochondrial fission factor (MFF), optic atrophy protein 1(OPA1). ResultCompared to the sham group, the left ventricular end diastolic diameter (LVIDd) and left ventricular end systolic diameter (LVIDs) were significantly increased in model group (P<0.01), while the left ventricular short axis shortening rate (LVFS) and left ventricular ejection fraction (LVEF) were significantly decreased (P<0.01). There were inflammatory cell infiltration and obvious pathological injury in myocardial tissue. ROS, MDA levels and myocardial cell apoptosis rate were significantly increased (P<0.01), SOD level, ATP content, and membrane potential were significantly decreased (P<0.01). The activity of mitochondrial respiratory chain complexes (Ⅰ-Ⅳ) was significantly decreased (P<0.01). Levels of p-Drp1, Fis1, MFF proteins were significantly up-regulated (P<0.01), while Sirt3, p-AMPK, OPA1 proteins level were significantly down-regulated (P<0.01). Compared with model group, LVIDd and LVIDs were significantly decreased (P<0.01), LVEF and LVFS were significantly increased (P<0.01). Inflammatory cell infiltration and pathological damage of myocardial tissue were significantly relieved. ROS, MDA levels and myocardial cell apoptosis rate were significantly decreased in Linggui Zhugantang group and Captopril group (P<0.01), SOD level, ATP content, and membrane potential significantly increased (P<0.01). The activity of mitochondrial respiratory chain complexes (Ⅰ-Ⅳ) increased significantly (P<0.01),and p-Drp1, Fis1, MFF protein levels were significantly down-regulated (P<0.01), Sirt3, p-AMPK, OPA1 protein were significantly up-regulated (P<0.01). ConclusionLinggui Zhugantang can alleviate oxidative stress and apoptosis damage of myocardial cells, maintain mitochondrial function stability, and its effect may be related to mitochondrial mitosis fusion and Sirt3/AMPK signaling pathway.

ObjectiveTo establish the characteristic sugar spectrum of polysaccharides, oligosaccharides and monosaccharides of wild-simulated and transplanted Astragali Radix, and find out the difference of the sugar spectrum between the two, so as to provide a basis for quality evaluation of Astragali Radix. MethodThe relative molecular weight distribution of polysaccharides from 18 batches of wild-simulated Astragali Radix and 12 batches of transplanted Astragali Radix were characterized by high performance liquid chromatography-evaporative light scattering detection(HPLC-ELSD) to establish the characteristic chromatograms of two kinds of polysaccharides. The difference in the peak area ratio of APS-Ⅱ, a polysaccharide component with a relative molecular weight of 10 kDa, in two kinds of Astragali Radix was analyzed, and the critical value of peak area ratio of APS-Ⅱ was determined by receiver operating characteristic(ROC) curve. At the same time, APS-Ⅱ was partially acid-hydrolyzed by trifluoroacetic acid(TFA) to establish characteristic spectra of two kinds of oligosaccharides from Astragali Radix based on HPLC-ELSD, and the characteristics of differential oligosaccharides were found by principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA). Two kinds of APS-Ⅱ were completely acid-hydrolyzed by TFA and derivatized to establish characteristic spectra of two kinds of monosaccharides from Astragali Radix based on HPLC, PCA and OPLS-DA were performed on the peak area ratio of two kinds of monosaccharides to explore the differences in the composition of two kinds of APS-Ⅱ monosaccharides. ResultThe characteristic sugar spectrum of polysaccharides from Astragali Radix showed that the peak area ratio of APS-Ⅱ was the main difference, and the peak area of APS-Ⅱ of wild-simulated and transplanted Astragali Radix were 89.17%-97.17% and 80.14%-91.96%, respectively. The ROC curve determined the critical value of 92.28% for the difference of APS-Ⅱ peak area ratio of the two kinds of Astragali Radix. The multivariate analysis of APS-Ⅱ oligosaccharides revealed that the peak area ratio of oligosaccharides with polymerization degree≥10 was the main difference, which ranged from 11.835%-19.092% for wild-simulated products and 2.778%-7.017% for transplanted products. The results of monosaccharide characteristic sugar spectrum analysis showed that both Astragali Radix species consisted of six monosaccharides, and glucose and arabinose were the differential monosaccharide fractions. The peak area ratios of glucose and arabinose in wild-simulated products were 85%-93.9% and 2.7%-5.8%, respectively, while those of transplanted products were 74.3%-87.3% and 5.3%-10.7%, suggesting that the structures of the two polysaccharide fractions APS-Ⅱ of Astragali Radix may be different. ConclusionThe difference of sugar spectrum between two kinds of Astragali Radix may be related to the content and structure of APS-Ⅱ, and this study may provide a reference for the study of carbohydrates in Astragali Radix and the quality evaluation of medicinal materials.
