Objective To investigatethe relationship between gastroesophageal reflux disease (GERD) symptoms and clinicopathological characteristics, p53 expression, and survival of Chinese patients with esophageal adenocarcinoma. Methods A total of 3882 patients with esophageal adenocarcinoma, 970 matched patients with esophageal squamous cell carcinoma, and 970 matched patients with gastric cardia adenocarcinoma were included to compare the incidence of GERD symptoms. Patients with esophageal adenocarcinoma were divided into two groups according to the presence and absence of GERD symptoms. The differences in clinicopathological characteristics and p53 expression between the two groups were compared by chi-square test, and the differences in survival between the two groups were compared by landmark analysis. Results The incidence of GERD symptoms increased successively in esophageal squamous cell carcinoma, esophageal adenocarcinoma, and gastric cardia adenocarcinoma. In patients with esophageal adenocarcinoma, the proportions of male, less than 65 years old, lower thoracic tumors, tumors without squamous cell carcinoma, poorly differentiation, early tumors (stage 0-I), and p53-positive tumors in the group with GERD symptoms were higher than those in the group without GERD symptoms; moreover, the long-term survival (≥15 years) was better. Conclusion GERD symptom is an important clinical sign of esophageal adenocarcinoma. It is closely related to specific clinicopathological characteristics, p53 overexpression, and good long-term prognosis.

ObjectiveTo characterize the evidence distribution and methodological quality of randomized controlled trials （RCTs） on oral Chinese herbal medicine （CHM） for atopic dermatitis （AD） based on evidence mapping. MethodsSeven databases （CNKI， Wanfang Data， VIP， CBM， Cochrane Library， PubMed， and Embase） and the Chinese Clinical Trial Registry were searched for the RCTs in Chinese and English. Evidence distribution was presented graphically and textually， and methodological quality was assessed via the Cochrane Risk of Bias tool （ROB 1.0）. ResultsA total of 168 RCTs were included. The number of annual publications showing an increasing trend， and 72.6% RCTs had sample sizes of 51-100 participants. The studies evaluated 108 distinct CHM interventions categorized as decoctions， granules， Chinese patent medicines， and extracts. Compound Glycyrrhizin was the most frequently used， followed by Xiaofengsan and Chushi Weiling decoction. Among the RCTs， 57.1% had the treatment courses of 4-8 weeks. Outcome measures predominantly focused on clinical response rate， skin lesion severity scores， and adverse events， with less attention to TCM symptom scores， skin barrier function， and relapse rates. The overall risk of bias was generally high. ConclusionWhile CHM for AD is a research hotspot and demonstrates clinical advantages， the related studies have problems such as unclear clinical positioning， poor research standardization and methodological quality， and insufficient prominence of TCM clinical advantages. Large-sample， methodologically rigorous， and high-quality studies are needed to enhance the evidence base for CHM in treating AD.

Linxian County in Henan Province, Northern China is known as the region with the highest incidence and mortality rate of esophageal cancer worldwide. Since 1959, the Henan medical team has conducted field work on esophageal cancer prevention and treatment in Linxian. Through three generations of effort exerted by oncologists over 65 years of research on esophageal cancer prevention and treatment in Linxian, the incidence rate of esophageal squamous cell carcinoma in this area has dropped by nearly 50%, and the 5-year survival rate has increased to 40%, reaching the international leading level. This article aims to summarize the history, present opportunities and new challenges, and explore the experience of esophageal cancer prevention and treatment in Linxian (referred to as the “Linxian experience”), providing reference and guidance to cancer prevention and treatment research in China.

Objective:To analyze the efficacy and prognostic factors of fractionated stereotactic radiotherapy (FSRT) for patients with breast cancer brain metastases (BCBM).Methods:Medical records and follow-up data of BCBM patients who underwent FSRT in Cancer Hospital Chinese Academy of Medical Sciences, Shenzhen Center and Shenzhen People's Hospital from August 2019 to May 2023 were collected. The R Studio platform of the R version 4.2.1 statistical software was applied to analyze patients' baseline characteristics, 1- and 2-year local brain control (LBC), overall survival (OS) and distant brain control (DBC) and corresponding median failure-free survival, draw survival curve using Kaplan-Meier method. Prognostic factors were screened by univariate analysis and multivariate analysis (Cox regression).Results:Cumulatively, 52 patients (163 metastases in total) had a median survival follow-up of 22.1 months, 83% were<60 years old. Molecular typing: 13 cases (25%) were positive for human epidermal growth factor receptor 2 (HER2+) / hormone receptor negative (HR-), 2 cases (4%) were luminal A, 26 cases (50%) were luminal B, and 11 cases (21%) were triple negative. The median number of brain metastases was 2 (range: 1 - 17). Follow-up outcomes: the median OS was 34.0 months, with 1- and 2-year OS rates of 85.6% and 65.4%, respectively; the median LBC was 20.6 months, with 1- and 2-year LBC rates of 79.2% and 45.2%, respectively; and the median DBC was 10.3 months, with 1- and 2-year DBC rates of 46.7% and 28.9%, respectively. During follow-up, 13 patients underwent salvage local therapy (10 FSRT); 5 developed radiation necrosis (1 symptomatic). Prognostic factor analysis: absence of extracranial organ metastases (compared with ≥3) was a protective factor for OS, P<0.05. For LBC, fewer (1 - 2) extracranial organ metastases (compared with ≥3), and single brain metastasis (compared with ≥2) were favorable prognostic factors , while N 3 staging upon initial diagnosis was a poor prognostic factor (all P<0.05). For DBC, brain metastasis after surgery was a good prognostic factor, while complicated with lung metastasis and asymptomatic brain metastasis at the first diagnosis were poor prognostic factors (all P<0.05). Conclusions:FSRT yields relatively good LBC and poor DBC for BCBM patients. A certain percentage of patients require salvage FSRT during follow-up, but OS is maintained acceptable and the radiation necrosis is tolerable. Among the prognostic factors, the absence of extracranial metastatic organs is a good prognostic factor for OS; patients with single brain metastasis, fewer extracranial metastatic organs, and non-N 3 staging upon initial diagnosis can obtain better LBC after FSRT.

This study investigated the regulatory potential of salidroside (SAL), a primary active compound in Rhodiola rosea L., on osteoclast differentiation by modulating the hypoxia-inducible factor 1-alpha (HIF-1a) pathway in osteoblasts. Luciferase reporter assay and chromatin immunoprecipitation (ChIP) assay were employed to validate whether the receptor activator of nuclear factor-?B ligand (RANKL) is the downstream target gene of HIF-1a in osteoblasts. The study also utilized lipopolysaccharide (LPS)-induced mouse osteolysis to examine the impact of SAL on osteolysis in vivo. Furthermore, conditioned medium (CM) from SAL-pretreated osteoblasts was used to investigate the paracrine effects on osteoclastogenesis through the HIF-1a pathway. Hypoxic condition-induced overexpression of HIF-1a upregulated RANKL levels by binding to the RANKL promoter and enhancing transcription in osteoblastic cells. In vivo, SAL significantly alleviated bone tissue hypoxia and decreased the expression of HIF-1a by downregulating the expression of RANKL, vascular endothelial growth factor (VEGF), interleukin 6 (IL-6), and angiopoietin-like 4 (ANGPTL4). In the paracrine experiment, conditioned media from SAL-pretreated osteoblasts inhibited differentiation through the HIF-1a/RANKL, VEGF, IL-6, and ANGPTL4 pathways. RANKL emerges as the downstream target gene regulated by HIF-1a in osteoblasts. SAL significantly alleviates bone tissue hypoxia and bone loss in LPS-induced osteolysis through the HIF-1a/RANKL, VEGF, IL-6, and ANGPTL4 pathways. SAL inhibits osteoclast differentiation by regulating osteoblast paracrine secretion.
