Hormone receptor (HR)-positive/HER2-negative early breast cancer is the most common subtype of breast cancer, and endocrine therapy serves as the cornerstone of adjuvant treatment. In recent years, with the publication of key clinical trials such as SOFT, TEXT, and monarchE, and breakthroughs in novel agents studies like lidERA, the endocrine therapy strategy for HR-positive/HER2-negative early breast cancer has evolved toward increased precision and intensity. This article systematically reviews the latest advances in endocrine therapy, focusing on the consolidation of ovarian function suppression as a standard for high-risk premenopausal patients with updated follow-up evidence, the benefit-risk assessment of extended endocrine therapy, and the current application and interdrug differences of CDK4/6 inhibitors in the adjuvant setting. This manuscript also addresses existing challenges, including optimizing treatment-related quality of life and precisely identifying beneficiary populations, and briefly introduces the clinical trial progress of novel agents, such as oral selective estrogen receptor degraders. Furthermore, it outlines evidence-based strategies for ovarian protection during chemotherapy and fertility preservation for young patients. This review aims to provide clinicians with a comprehensive perspective, balancing the pursuit of maximal efficacy with patients′ long-term quality of life and individualized needs.

Objective To observe the efficacy and safety of neoadjuvant sintilimab combined with chemotherapy in the treatment of patients with locally advanced resectable esophageal squamous cell carcinoma (ESCC). Methods Clinical data were collected from patients with locally advanced resectable ESCC who received neoadjuvant immunotherapy combined with chemotherapy followed by surgical treatment at the Department of Thoracic Surgery of Jining No.1 People's Hospital from April 2020 to April 2022. The endpoints included major pathological response (MPR), pathological complete response (pCR), R0 resection rate, safety, and postoperative survival. Results A total of 43 patients with ESCC who received at least one cycle of neoadjuvant immunotherapy before surgery were included. Among them, there were 31 males and 12 females with a median age of 65 years (interquartile range: 58-69). All patients successfully completed the surgery without any surgical delays. The pCR rate was 14.0% (6/43), the MPR rate was 58.1% (25/43), and the R0 resection rate was 97.7% (42/43). Patients exhibited reliable safety during neoadjuvant therapy and postoperatively. The 2-year overall survival and disease-free survival rates were 90.7% and 81.4%, respectively. Kaplan-Meier survival analysis and log-rank test revealed lower recurrence rates and better survival in the MPR patients compared to the non-MPR patients. Conclusion The combination of neoadjuvant sintilimab and chemotherapy in the treatment of patients with locally advanced resectable ESCC has demonstrated significant clinical efficacy, while also being safe and reliable.

ObjectiveTo explore the mechanism of Huashi Baidu granules in treating influenza A （H1N1） virus infection based on the gut-lung axis. MethodsBALB/c mice were randomly assigned into a blank control group， a model control group， a positive control （oseltamivir phosphate capsules， 19.5 mg·kg^-1） group， and a Huashi Baidu granules （17.81 g·kg^-1） group. Mice in other groups except the blank control group were instilled nasally by H1N1 viral fluid for the modeling of influenza viral pneumonia and treated with corresponding drugs once daily by gavage for 5 consecutive days. The mouse lung index was calculated， and pathological changes in the lung and colon tissue were observed. Western blot was employed to quantify the expression levels of nucleotide-binding oligomeric domain-like receptor protein 3 （NLRP3）， cysteinyl aspartate-specific proteinase -1 （Caspase-1）， apoptosis-associated Speck-like protein containing a CARD （ASC）， gasdermin D （GSDMD）， interleukin-18 （IL-18）， IL-1β， and colonic tight junction protein 1 （CLDN1）， and Occludin in the lung and colon tissue. Non-targeted metabolomics was employed to analyze the metabolic profiles of the lung tissue and intestinal contents. The 16S rRNA sequencing was performed to analyze the gut microbiota structure in intestinal contents. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the 5-hydroxytryptamine （5-HT） levels in the serum， lung tissue， and colon tissue. ResultsCompared with the blank control group， the model control group showed elevated lung index， marked inflammatory cell infiltration and alveolar structural destruction in the lung tissue， obvious inflammatory cell infiltration and mucosal epithelial damage in the colon tissue， upregulated protein levels of NLRP3 inflammasome pathway proteins NLRP3， Caspase-1， GSDMD， IL-1β， and IL-18 in the lung and colon tissue （P<0.05， P<0.01）， downregulated protein levels of CLDN1 and Occludin in the colon tissue （P<0.05， P<0.01）. Compared with the model control group， Huashi Baidu Granules reduced the lung index （P<0.01）， alleviated pathological damage in the lungs and colon， inhibited the expression of NLRP3， Caspase-1， GSDMD， IL-1β， and IL-18 in lung and colon tissue （P<0.05， P<0.01）， and upregulated the expression of CLDN1 and Occludin in the colon tissue （P<0.05， P<0.01）. Metabolomics analysis showed that Huashi Baidu Granules downregulated the 5-HT pathway and arachidonic acid metabolism pathway in the lung and colon tissue， while upregulating nucleotide metabolism and TCA cycle. Compared with the blank control group， the model control group exhibited elevated levels of 5-HT in the serum， lung tissue， and colon tissue （P<0.01）. The intervention with Huashi Baidu Granules lowered the levels of 5-HT in the serum （P<0.05） and the lung and colon tissue （P<0.01）. Huashi Baidu Granules increased the diversity of gut microbiota， enriched beneficial bacteria such as Blautia， and inhibited pathogenic bacteria such as Desulfovibrio. ConclusionHuashi Baidu Granules significantly alleviate lung inflammation and pathological damage in mice infected with influenza A （H1N1） virus， reshape the intestinal microecology， and repair the intestinal barrier. It may exert cross-organ regulation by inhibiting the cascade of "gutogenic 5-HT release-circulatory transport-pulmonary 5-HT receptor activation-NLRP3 inflammasome assembly." It exerts therapeutic effects on influenza viral pneumonia through the gut-lung axis. This study provides a modern biological interpretation for the TCM theories of interior-exterior relationship between the lung and large intestine and simultaneous treatment of the lung and intestine.

Attention Deficit Hyperactivity Disorder (ADHD) is a chronic neurodevelopmental disorder with an estimated prevalence of approximately 6.4% among children and adolescents aged 6 to 16 in China. The etiology and pathogenesis of ADHD remain incompletely understood, and conventional treatment methods often have limited effectiveness. With advances in research into the etiology of ADHD, nutritional intervention has emerged as a potential adjunctive treatment and has garnered widespread attention. Multiple studies have demonstrated the potential effectiveness of nutritional interventions for ADHD. This review aims to summarize the progress in nutritional interventions for pediatric ADHD, particularly focusing on nutrient-level interventions (including polyunsaturated fatty acids, minerals, and vitamins), nutrition-related factors (such as probiotics), as well as the combined use of multiple nutrients and dietary nutrition (including dietary patterns). We will analyze and discuss the effectiveness of different nutritional interventions to provide a valuable reference for clinical nutritional diagnosis and treatment of the disease.

Objective:To investigate clinical efficacy and safety of dupilumab in the treatment of moderate to severe atopic dermatitis (AD) complicated with asthma.Methods:A self-controlled study before and after treatment was conducted to retrospectively analyze 45 patients with moderate to severe atopic dermatitis combined with asthma who received dupilumab in the respiratory allergy clinic of North Theater Command General Hospital from January 2021 to May 2024, which age ≥12 years, including 27 males, 18 females. The treatment period was 4 to 12 months. All patients were treated with dupilumab combined with inhaled glucocorticoids and long-acting beta2-receptor agonists, as well as symptomatic drugs for atopic dermatitis. Analyze the clinical data of the patients before and after treatment, including lung function, asthma and AD-related assessment scales. Generalized estimation equation was used to analyze the simple effect of time on the repeated measurement data following non-normal distribution, and Wilcoxon signed rank test was used to compare the differences of each observation index before and after treatment.Results:Among 45 patients with moderate to severe atopic dermatitis complicated with asthma, after treatment with dupilumab, the FEV 1 increased from 2.39 (1.87, 2.83) L at baseline to 2.50 (1.84, 2.97) L 3 months after treatment ( Z=2.417, P=0.016), 2.60 (1.95, 3.14) L 6 months after treatment ( Z=2.896, P=0.004); the FEV 1pred% increased from 74.10% (67.70%, 78.75%) at baseline to 77.09% (68.40%, 80.24%) at 3 months after treatment ( Z=2.574, P=0.010), and 77.20% (71.10%, 80.72%) at 6 months after treatment ( Z=2.861, P=0.004). Meanwhile, there were statistically significant differences in the ACT and Mini-AQLQ scales at 3, 6, and 12 months after treatment compared with those before treatment (ACT score Z=3.170, 4.216, 5.723; Mini-AQLQ score Z=3.231, 4.133, 5.826; all P<0.05). The EASI scale decreased from baseline 25.90 (18.95, 33.45) to 6.20 (1.15, 8.35) at 4 months after treatment ( Z=5.842, P<0.05) and 4.90 (2.75, 8.35) at 6 months after treatment ( Z=5.841, P<0.05), 4.00 (3.15, 5.05) at 12 months after treatment ( Z=5.841, P<0.05); The scores of each scale of IGA, NRS and DLQI decreased significantly compared with the baseline after 4 months, 6 months and 12 months of treatment, and this trend became more obvious with the extension of treatment time. The differences were statistically significant (IGA score Z=6.247, 6.070, 5.946; NRS score Z=5.960, 5.893, 5.879; DLQI score Z=5.880, 5.850, 5.848; all P<0.05). During treatment, 1 patient had local adverse reactions at the injection site and 1 patient had conjunctivitis. Conclusion:Dupilumab may have a positive effect on improving the clinical efficacy of patients with moderate to severe atopic dermatitis complicated with asthma. During the 12-month observation period, this biological agent generally demonstrated good safety characteristics.

Objective:To investigate multi-system involvement in Kennedy′s disease and its association with disease progression.Methods:We retrospectively reviewed the clinical, laboratory, and electrophysiological data from 48 genetically confirmed patients with Kennedy′s disease at the Department of Neurology, First Medical Center of the Chinese PLA General Hospital, between February 2016 and February 2024. The disease progression rate was calculated based on the functional scores at baseline and follow-up. Correlation analyses and multiple linear regression models were employed to assess the relationships among clinical variables and to identify potential predictors of disease progression.Results:The age of muscle weakness onset ranged from 16 to 66 years (mean 42±11 years), with a diagnostic delay of 5.0 (3.0, 9.8) years. Lower limb weakness was the most common initial symptom in 72.9% (35/48) of patients, and 37.5% (18/48) exhibited non-motor manifestations prior to the onset of weakness. Core motor manifestations included bulbar weakness (89.6%, 43/48) and symmetric proximal limb weakness (83.3%, 40/48), frequently accompanied by gynecomastia (74.2%, 23/31) and sexual dysfunction (64.6%, 31/48). The median CAG repeat length was 43 (42, 46), which showed a significant negative correlation with the age at onset ( r=-0.406, P=0.004). Patients with CAG repeats > 43 had a higher prevalence of sexual dysfunction. Elevated serum muscle enzymes were observed in 97.9% (47/48), and abnormal sex hormone levels were detected in 81.2% (39/48). Sensory neuropathy was present in 68.1% (32/47), with CAG repeat length inversely correlating with compound muscle action potential (CMAP) amplitudes in the median ( β=-0.29; t=-2.27, P=0.029) and ulnar ( β=-0.22; t=-2.23, P=0.031) nerves. Low-frequency repetitive nerve stimulation (RNS) revealed a decrement in 43.3% (13/30) of patients, most commonly affecting the axillary and spinal accessory nerves. The disease progression rate was 1.3±0.3 (range: 0.5-2.0). Furthermore, serum creatine kinase-MB (CK-MB) levels were negatively correlated with disease progression rate ( r=-0.303, P=0.036). Conclusions:Kennedy′s disease presents with diverse initial manifestations and frequent multi-system involvement. Non-motor manifestations may precede muscle weakness, serving as valuable clues for early diagnosis. Widespread sex hormone abnormalities (particularly testosterone/luteinizing hormone dysregulation) support the role of androgen insensitivity in disease pathogenesis. Sensory neuropathies are frequent and not length-dependent. The presence of decremental responses on low-frequency RNS suggests neuromuscular junction dysfunction, which may underlie motor impairment in patients with Kennedy′s disease. Finally, serum CK-MB may serve as a potential biomarker for disease progression.

Objective:Based on the activities of Helicobacter pylori ( HP) screening in Jiangsu Province in 2024, to evaluate the overall management ability in HP screening, testing, treatment and follow-up in primary medical facilities. Methods:From May 15 to October 18, 2024, the data of HP screening and treatment were retrospectively collected from 79 township health centers, community hospitals, and community health service centers in Jiangsu Province. The rates of screening completion, urea breath test (UBT) completion, treatment rate, UBT follow-up completion, and HP eradication were analyzed. Chi-square test was used for statistical analysis. Results:The completion rate of HP screening was 94.45% (15 489/16 400). There were 6 604 cases (42.64%) with serum HP antibody positive among the 15 489 individuals who completed screening. The positive rate of serum HP antibody in males was higher than that in females (44.77%, 2 643/5 904 vs. 41.32%, 3 961/9 585), and the difference was statistically significant ( χ2=17.69, P<0.001). The positive rates of serum HP antibody in screened individuals aged 18 to 19, 20 to 39, 40 to 59, and 60 to 75 years old were 22.38% (32/143), 36.12% (1 168/3 234), 45.01% (3 240/7 199), and 44.05% (2 164/4 913), respectively, and the difference was statistically significant( χ2=100.73, P<0.001). Among the 6 604 HP antibody-positive individuals, 4 381 cases completed UBT, with a UBT completion rate of 66.34% (4 381/6 604). There were 3 197 individuals with both HP serum antibody and UBT positive, the consistency rate of the 2 tests was 72.97% (3 197/4 381). Totally 2 737 cases received treatment, with a treatment completion rate of 85.61% (2 737/3 197); 2 327 individuals underwent UBT follow-up, with a follow-up completion rate of 85.02% (2 327/2 737). During follow-up, the result of UBT was negative in 1 982 individuals, and the HP eradication rate was 85.17% (1 982/2 327). Conclusions:There are deficiencies in the completion rate of HP screening, testing, treatment, and follow-up in primary hospitals, especially in the completion rate of UBT, which may be related to cognitive insufficiency for HP in residents. It is necessary to strengthen the training of physicians′ abilities in primary hospitals, optimize the allocation of drug resources, enhance health education, and increase residents′ participation and compliance.

Autism spectrum disorder (ASD) is a neurodevelopmental condition originating in early life, presenting significant challenges for affected families and society. ASD is characterized by atypical brain development occurring throughout gestation. Maternal diet during pregnancy plays a crucial role in ASD pathogenesis. Specifically, prenatal multivitamin supplementation and adequate vitamin D intake may reduce ASD risk; similar protective effects have been associated with polyunsaturated fatty acid (PUFA) and iron consumption. Although research findings are inconsistent, prenatal nutritional interventions represent a promising strategy for mitigating the future risk of mental health and other disorders in offspring. Therefore, this article reviews key nutrients implicated in ASD risk during pregnancy, to provide a theoretical foundation for developing precise perinatal nutritional intervention plans.
