The benefit of postoperative adjuvant therapy for patients with resectable esophageal squamous cell carcinoma (ESCC) is not yet supported by high-level evidence. This review analyzes the role of adjuvant therapy by examining the discrepancy between clinical needs and guidelines, its historical evolution, recent advances in high-risk factors, and future outlooks. We provide a detailed discussion of high-risk factors used for patient selection, including lymph node positivity, and for node-negative patients, features such as tumor length, location, T stage, extent of lymph node dissection, differentiation, vascular and neural invasion, laboratory indices, and molecular markers. The goal is to inform the development of individualized precision treatment strategies for resectable ESCC.

Ischemic stroke （IS） represents a major global health challenge with complex pathological mechanisms. Although modern therapies such as intravenous thrombolysis and endovascular thrombectomy have advanced， their application remains constrained by narrow therapeutic time windows， hemorrhagic risks， and uneven distribution of medical resources. Traditional Chinese medicine （TCM） demonstrates unique value in the prevention and treatment of IS， owing to its multi-component， multi-target， and holistic regulatory characteristics. This review summarized the molecular mechanisms by which active ingredients and compound formulations of TCM exert therapeutic effects against IS through the regulation of inflammatory responses， oxidative stress， excitatory toxicity， apoptosis， and autophagy. Studies have indicated that components such as curcumin， baicalin， and astragaloside Ⅳ inhibit microglial activation and the nucleotide-binding oligomerization domain （NOD）-like receptor protein 3 （NLRP3） inflammasome to attenuate neuroinflammation， activate the nuclear factor erythroid 2-related factor 2（Nrf2）/heme oxygenase-1 （HO-1） pathway to alleviate oxidative stress， modulate glutamate receptor function to counteract excitatory toxicity， and regulate the B-cell lymphoma 2（Bcl-2）/Bcl-2-associated X protein （Bax）， cysteine aspartate-specific protease （Caspase）， and phosphatidylinositol 3 kinases （PI3K）/protein kinase B （Akt） signaling pathways to suppress neuronal apoptosis. Recent research has further revealed that TCM can modulate ferroptosis by targeting key proteins glutathione peroxidase 4 （GPX4） and acyl-coenzyme A synthetase long-chain family member 4 （ACSL4） to maintain iron homeostasis， intervene in the "microbiota-gut-brain axis" to ameliorate dysbiosis and reduce neuroinflammation， utilize exosomes for brain-targeted drug delivery， and influence neural repair processes through epigenetic regulation. Furthermore， the review discussed the integrated mechanisms of compound formulations， such as Buyang Huanwu Decoction， in improving cerebral microcirculation and promoting neurovascular remodeling via multi-component synergy. It also analyzed the strategy and advantages of integrating TCM with Western medicine for IS treatment， providing a novel theoretical foundation and research directions for future investigations and clinical translation of TCM in IS management.

Background Benign prostatic hyperplasia (BPH) is a common chronic urinary disease in middle-aged and older men, yet the impact of long-term exposure to atmospheric particulate matter (PM) on its pathogenesis remains unclear. Objective To investigate the association between PM exposure and the risk of incident BPH in middle-aged and older men. Methods Based on four waves of follow-up data (2011–2018) from the China Health and Retirement Longitudinal Study (CHARLS), 4766 participants were enrolled. Robust Poisson regression models were employed to assess the association between exposure to PM (PM₁, PM_2.5, and PM₁₀) and the risk of incident BPH. Relative risks (RR) and their corresponding 95% confidence intervals (95%CI) were calculated. Dose-response relationships were fitted using restricted cubic splines (RCS). Subgroup analyses were performed to explore potential effect modifications, and multiple imputation was used to handle missing data. Results Over a mean follow-up of 6 years, 914 incident BPH cases were identified among the4766 participants (cumulative incidence: 19.18%). After adjusting for confounders, each 10 μg·m⁻³ increase in PM₁, PM_2.5, and PM₁₀ concentrations was associated with a 13.1% (RR=1.131, 95%CI: 1.063, 1.203), 8.5% (RR=1.085, 95%CI: 1.050, 1.122), and 5.1% (RR=1.051, 95%CI: 1.034, 1.069) increased risk of BPH, respectively. RCS analysis showed that no nonlinear relationship was found between PM₁ and PM_2.5 and the risk of BPH (P>0.05); however, a nonlinear association was observed for PM₁₀ (P=0.03), with the risk increment slowing beyond 100 μg·m⁻³. Subgroup and sensitivity analyses confirmed the robustness of these findings. Conclusion Long-term exposure to ambient particulate matter may be associated with an increased risk of incident BPH in middle-aged and older men.

OBJECTIVE: Left ventricular remodeling induced by myocardial ischemia/reperfusion injury (MI/RI) is a common cardiac dysfunction. Accumulating evidence has demonstrated that autophagy plays a vital role in protecting against ventricular remodeling. This study aims to investigate the performance of Compound Danshen Tablets (CDT) in rescuing ventricular remodeling and whether autophagy as the potential mechanism. METHODS: The left anterior descending arteries of rats were temporarily ligated for 30 min to construct the MI/RI model. Ventricular remodeling was induced by reperfusion for 28 d, during which the MI/RI rats were administered CDT (300 mg/kg and 600 mg/kg), atorvastatin (2 mg/kg), and diltiazem (16 mg/kg). Cardiac function and structure were examined by echocardiography. Immunohistochemistry, Masson's trichrome staining, and hematoxylin-eosin (HE) staining were utilized to assess the fibrosis and histological alterations in the heart tissue. The expression of autophagy-related proteins was detected using Western blotting. RESULTS: CDT attenuated the cardiac dysfunction, structural changes, histopathological changes and fibrosis induced by MI/RI. CDT significantly enhanced the level of Beclin1 and microtubule-associated protein 1 light chain 3 beta (LC3β), and reduced p62 levels in MI/RI rats. Moreover, CDT significantly increased the phosphorylation of adenosine monophosphate-activated protein kinase (AMPK) and inhibited mammalian target of rapamycin (mTOR) phosphorylation. CONCLUSION CDT ameliorated MI/RI-induced ventricular remodeling by activating autophagy and improving autophagic flux via the AMPK/mTOR signaling pathway.

In recent years, the incidence of multiple primary lung cancer (MPLC) has been increasing, and it cannot be ignored in clinical practice. The treatment of MPLC is still controversial, but surgical treatment is recognized as the most important treatment. However, current studies have shown that the treatment of MPLC needs to develop multimodal treatment according to different patients. This review summarizes multiple treatment method for MPLC, including surgery, ablation, chemotherapy, radiotherapy, targeted therapy, and immunotherapy in order to enhance understanding of MPLC treatment.

OBJECTIVE To evaluate cerebrospinal fluid(CSF)flow dynamics and volume changes of pulsatile tinnitus(PT)patients caused by sigmoid sinus wall dehiscence(SSWD)with different intracranial pressure via MRI.METHODS Prospective enrolled 35 SSWD-PT patients with intracranial hypertension,25 SSWD-PT patients with normal intracranial pressure and 35 age-,sex-matched healthy controls.Demographic characteristics were recorded.Intracranial pressure was assessed by the index of transverse sinus stenosis(ITSS)and morphology changes.CSF flow dynamics were evaluated via phase-contrast magnetic resonance imaging(PC-MRI)and CSF volume were evaluated via three-dimensional T1-weighted turbo field echo(3D T1-TFE)sequence and ITK-SNAP software.Compared the differences of each index between three groups.RESULTS The mean flux and regurgitant fraction were significantly different among the three groups(P<0.05).The intracranial hypertension group presented significantly decreased mean flux(MF)and significantly increased regurgitant fraction(RF)compared to controls(P<0.017).There were no significant differences in MF and RF of normal intracranial pressure group compared with intracranial hypertension group and control group(P>0.017).There were no statistical differences in age,sex,body mass index,forward flow volume,backward flow volume,mean velocity,peak velocity,stroke volume and CSF volume(P>0.05).CONCLUSION SSW D-PT patients have abnormal changes in CSF,and those with increased intracranial pressure are more obvious.These changes may be associated with abnormal hemodynamics in the sigmoid sinus and the occurrence of PT.

BACKGROUND:Disruption of biological rhythms(circadian rhythms)is a typical problem associated with aging.Maintaining the normal function of biological rhythms may be a promising anti-aging strategy.Expression of nuclear factor erthroid 2-related factor 2(Nrf2)is biologically regulated.The glycogen synthase kinase 3(GSK3)system represents a"regulatory valve"that controls subtle oscillations in Nrf2 levels.Circadian changes in the transcript levels of antioxidant genes can influence the response of organisms to oxidative stress.However,the specific molecular mechanism of GSK3/Nrf2 in regulating organismal aging is still puzzling. OBJECTIVE:To search for the general pattern of GSK3/Nrf2-regulated biological rhythms in organismal aging by reviewing the literature in this field. METHODS:The bibliographic method was used to search,review and screen the relevant literature using the keywords of"glycogen synthase kinase 3,nuclear factor erthroid 2-related factor 2,biorhythms and aging"to lay a theoretical foundation for the analysis of the whole paper.Comparative analysis method,through reading and analyzing the obtained literature,was performed to compare the similarities and differences between the literature,thereby providing reasonable theoretical support for the argument.Further comparative analysis of the literature was conducted to clarify the relationship between the relevant indicators as well as the ideas for analysis throughout the text. RESULTS AND CONCLUSION:GSK3 can indirectly regulate Nrf2 expression through the regulation of rhythm genes.GSK3 and Nrf2 are components of anti-aging programs and are associated with biological rhythms.In addition,GSK3/Nrf2 is involved in several metabolic pathways,including those associated with age-related diseases(type 2 diabetes and cancer)and neurodegenerative diseases.

Objective:To evaluate the effect of an opioid-sparing anesthesia strategy primarily using quadratus lumborum block combined with esketamine on early postoperative recovery in patients undergoing laparoscopic radical resection of colon cancer.Methods:This study was a randomized controlled trial. From January 2023 to July 2024, 72 patients of either sex, aged 45-65 yr, with body mass index of 18-25 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, undergoing elective laparoscopic radical resection of colon cancer with general anesthesia at Yichang Central People′s Hospital, were divided into 2 groups ( n=36 each) using a random number table method: control group (group C) and opioid-sparing anesthesia strategy group (group D). Anesthesia was induced with sufentanil and propofol and maintained with propofol and remifentanil in group C. In group D, ultrasound-guided quadratus lumborum block was performed before the start of anesthesia, and anesthesia was induced with esketamine, propofol and lidocaine and maintained with esketamine, propofol, low-dose remifentanil, lidocaine and magnesium sulfate. Patient-controlled intravenous analgesia was carried out at the end of surgery until 48 h postoperatively, using dezocine for rescue analgesia. The Quality of Recovery-15 scores were assessed and recorded at 1 day before operation and 1, 3 and 7 days after operation. Ramsay sedation scores were recorded at 2, 6, 12, 24 and 48 h after surgery. The effective pressing times of patient-controlled analgesia and requirement for rescue analgesia were recorded within 24 h after surgery and during the 24-48 h postoperative period. The intraoperative consumption of opioid, emergence time, duration of postanesthesia care unit stay, time to first flatus, first ambulation time and length of postoperative hospital stay were also recorded. The postoperative complications were recorded during hospital stay and assessed with the Clavien-Dindo classification. Results:Compared with group C, the Quality of Recovery-15 scores were significantly increased at each time point after operation, Ramsay sedation scores were increased at 2, 6 and 12 h after operation, the effective pressing times of patient-controlled analgesia and rate of rescue analgesia were decreased in each postoperative period, the intraoperative consumption of remifentanil was reduced, the time to first flatus, first ambulation time and length of postoperative hospital stay were shortened, the incidence of nausea and vomiting was decreased ( P<0.05), and no significant change was found in the emergence time or duration of postanesthesia care unit stay in group D ( P>0.05). Conclusions:The opioid-sparing anesthesia strategy primarily using quadratus lumborum block combined with esketamine can raise the quality of early postoperative recovery in the patients undergoing laparoscopic radical resection of colon cancer.

Genetic factors are often involved in the pathogenesis of young adult stroke, and its subtype, atherosclerotic type of large arteries, may be caused by a combination of genetic and environmental factors, but little is known about its underlying pathogenesis. To provide clues for better understanding of identifying relevant stroke etiological genetic factors and adopting effective preventive strategies, the role of genetic factors in atherosclerosis and related risk factors was described, and the possible genetic mechanisms of large-artery atherosclerotic stroke in young people were explored, which may be further investigated in future research in the following areas: etiological typing of stroke in young people and the related genetic mechanisms; modifiable vascular risk factors and the development of secondary prevention strategies; high-resolution vascular imaging magnetic resonance imaging in the etiological typing of stroke in young people and the pathogenesis of premature atherosclerosis and vulnerable plaques.
