Objective:
To investigate the status of heat illness, knowledge awareness and adaptive behaviors of heat wave knowledge among food delivery riders, so as to provide a basis for optimizing heat wave response measures for food delivery riders.
Methods:
In November 2022, food delivery riders from a large food delivery platform in Ningbo City, Zhejiang Province were selected as survey subjects using a cluster sampling method. A self-designed electronic questionnaire was used to select demographic information, work status, lifestyle behaviors and disease history, heat illness status, knowledge awareness and adaptive behaviors of heatwave.
Results:
A total of 911 questionnaires were distributed, and 830 valid questionnaires were recovered, resulting in a valid response rate of 91.11%. Among the respondents, 796 (95.90%) were male, and 818 (98.55%) worked full-time. The mean age was (27.75±8.00) years. A total of 470 respondents (56.63%) had a work tenure of less than 1 year. The primary working hours were 8-<12 hours, with 504 people accounting for 60.72%. There were 108 cases of heatstroke, with an occurrence rate of 13.01%. And 286 people reported heat-related symptoms, with an occurrence rate of 34.46%. The overall awareness rate of heat wave knowledge was 73.22%, while the awareness rate of heat warning signal classification was relatively low at 9.04%. The heat wave cognition score was (5.86±1.31) points. There were statistically significant differences in heat wave cognition scores among food delivery riders of different ages, educational levels, family annual income, work tenures, and work durations (all P<0.05). Regarding positive adaptive behaviors, the number of riders paying attention to weather forecasts and actively learning about preventive measures was higher (734 people each, accounting for 88.43%). Regarding negative adaptive behaviors, the number of riders who often drank ice-cold beverages was higher (509 people, accounting for 61.33%). The heat wave adaptive behavior score was (6.88±1.77) points. There were statistically significant differences in adaptive behavior scores among riders with different educational levels, family annual income, work tenures, and smoking frequency (all P<0.05).
Conclusions
The occurrence rates of heatstroke and heat-related symptoms among food delivery riders are relatively high. The knowledge awareness and adaptive behaviors regarding heat wave are at a moderate level. It is suggested to strengthen health education, reinforce risk cognition of heat wave, and promote positive adaptive behaviors among food delivery riders.

ObjectiveTo investigate the effects of zinc finger E-box binding homeobox 1 (ZEB1) on the proliferation, migration, and invasion of lung adenocarcinoma H322 cells, as well as its underlying molecular mechanisms. MethodsThe gene expression characteristics of the transcription factor ZEB1 in lung adenocarcinoma were analyzed using data from the GEO and TCGA public databases. RT-qPCR and Western blot were employed to measure mRNA and protein expression levels of ZEB1 in lung adenocarcinoma cell lines (H322, A549, 95-D) and normal human bronchial epithelial cells (BEAS-2B). Lentiviral transduction was utilized to establish stable ZEB1-overexpressing (Oe-ZEB1) and vector control (Oe-NC) H322 cell lines. Cell proliferation was assessed using CCK-8, colony formation, and EdU assays, while apoptosis was evaluated by Hoechst33258/PI double staining. Wound healing and Transwell assays were performed to examine cell migration and invasion capabilities. Cell cycle distribution was determined by flow cytometry, and Western blot was used to analyze protein expression changes in relevant signaling pathways. ResultsThe findings from GEO and TCGA indicated that ZEB1 expression in lung adenocarcinoma varied with tumor malignancy grade. RT-qPCR and Western blot analyses revealed significantly higher ZEB1 expression in lung adenocarcinoma cell lines compared to BEAS-2B cells (P0.05). Results from the CCK-8, colony formation, EdU, wound healing, and Transwell assays demonstrated that, compared with the un-transfected control (Control) group, Oe-ZEB1 H322 cells exhibited enhanced proliferation, migration, and invasion capabilities (P0.05). Hoechst33258/PI double staining and flow cytometry analyses showed that, relative to the Control group, apoptosis was reduced in Oe-ZEB1 H322 cells (P0.05). Additionally, a decreased proportion of cells in the G1 phase and an increased proportion in the S phase were observed in Oe-ZEB1 cells, indicating accelerated cell cycle progression. Western blot analysis further revealed that, compared with the Control group, Oe-ZEB1 H322 cells exhibited upregulated expression of N-cadherin, mutant p53 (mutp53), and Cyclin D1 (P0.05), while expression levels of E-cadherin, murine double minute 2 (MDM2), and p21 were downregulated (P0.05). ConclusionOverexpression of ZEB1 promotes the proliferation, migration, and invasion of lung adenocarcinoma H322 cells and may facilitate cell cycle progression by modulating the MDM2/mutp53/p21 signaling pathway, thereby promoting the transition of cells from the G0/G1 phase to the S phase.

As an innovative form of combining traditional aromatherapy with modern nasal medicine delivery technology, "olfactory administration of Chinese medicine" carries the theoretical essence of traditional Chinese medicine (TCM), which is "moving and channeling Qi and fragrance, dredging and awakening the mind". Based on the systematic records of olfactory therapies in ancient books in emergency care, disorders of consciousness, lung system, and gynecological diseases, this paper examines the historical evolution of its clinical application, and elucidates the profound historical basis and theoretical feasibility of "olfactory administration of Chinese medicine" as a new form. Combined with the innovation and precise application of modern Chinese medicine olfactory agents in multi-system diseases such as nervous, respiratory, and cardiovascular diseases, this paper further analyzes the multi-dimensional mechanism of olfactory receptor pathway, olfactory brain pathway, nasal mucosal blood vessels, and lymphatic channels, and demonstrates its advantages of rapid onset, targeted brain entry, and systemic regulation. Under the background of continuous growth in the demand for external TCM treatment, continuous breakthroughs in the technology of nasal dosage forms, and increasingly accurate drug delivery paths, Chinese medicine olfactory agents have shown significant practical applicability and development potential. This study aims to provide theoretical support and practical direction for the system construction of this form.

Rice (Oryza sativa L.), as a thermophilic crop, is highly susceptible to cold stress during its growth process. Chilling injury at the plumule stage and seedling stage often affects the morphological development and leads to yield reduction of rice. The exploration and utilization of cold tolerance genes are among the most direct and effective approaches to address cold stress in rice. To identify quantitative trait loci (QTLs) associated with cold tolerance at plumule and seedling stages, in this study, we measured the seedling rates and survived seedling rates of the indica rice cultivar 'HZ', the japonica cultivar 'Nekken2', and their 120 recombinant inbred lines (RILs) under cold stress. A previously constructed high-density genetic linkage map was used for the mapping of the QTLs conferring cold tolerance at the plumule and seedling stages. A total of 4 QTLs for plumule-stage cold tolerance and 9 QTLs for seedling-stage cold tolerance were detected, with the maximum limit of detection reaching 5.20. Notably, a genetically overlapping QTL for both plumule and seedling stages was identified on chromosome 8, spanning a physical interval of 24 432 953-25 295 129 bp. Candidate genes within the detected QTL intervals were screened, and quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to analyze the gene expression during the plumule and seedling stages. The results revealed that LOC_Os03g06570, LOC_Os03g07100, LOC_Os06g08280, LOC_Os08g38440, LOC_Os08g39100, and LOC_Os08g39540 exhibited significantly differential expression between the parental lines. These genes were either significantly downregulated or upregulated under cold stress. Among them, the first three gene (LOC_Os03g06570, LOC_Os03g07100, and LOC_Os06g08280) were hypothesized to be key candidates regulating the cold tolerance of rice seedlings, while the latter three genes (LOC_Os08g38440, LOC_Os08g39100, and LOC_Os08g39540) were identified as comprehensive regulators of cold tolerance during both plumule and seedling stages. These findings lay a foundation for the fine mapping and cloning of cold tolerance genes at the plumule and seedling stages, providing valuable insights for breeding cold-tolerant rice varieties.

5.Application Progress of Virtual Reality Technology for the Treatment of Spinal Cord Injury
Journal of Sun Yat-sen University(Medical Sciences) 2025;46(3):391-400
Spinal cord injury (SCI) is a prevalent neurological disorder that often results in motor, sensory, cognitive, balance, and walking impairments, and can even lead to pain, significantly affecting the physical and mental health and quality of life of patients. Conventional treatment methods, primarily conducted in hospital settings, tend to be monotonous and lack engagement, leading to low patients’ compliance, motivation and cooperation. In contrast, virtual reality (VR) technology can serve as an effective adjunctive therapeutic approach, immersing patients in simulated virtual environments for functional training in specific contexts and tasks, thereby providing a sense of real experience to achieve assessment and therapeutic outcomes. The interactive and engaging nature of VR technology markedly enhances patients’ interest and motivation in treatment, offering new possibilities for home-based rehabilitation and presenting patients with alternative treatment options. This review systematically introduces the application of VR technology in the treatment of patients with SCI, focusing on its roles in assessing functional impairments, improving motor function, enhancing balance and walking abilities, alleviating pain, and promoting recovery from cognitive and psychological disorders, as well as its impact on other functional impairments and its combined use with other technologies. Furthermore, this article delves into the current advantages and limitations of VR technology, aiming to deepen the understanding of VR among physicians and therapists, promote its widespread clinical application, advance the field of rehabilitation medicine, provide theoretical foundations and directions for future research, and offer new insights and references for clinical practice.

Objective:
To explore the clinical and imaging characteristics of patients with regional odontodysplasia accompanied by hypodontia and to provide a reference for clinical diagnosis and treatment.
Methods:
This report presents the imaging manifestations, diagnosis, and treatment of a case of regional odontodysplasia (RO) accompanied by hypodontia. It includes a retrospective summary of the dynamic changes in the imaging characteristics of the affected teeth over a 5-year period, along with a comparative analysis of the literature. The patient was a 9-year-old female who presented to the Clinic of Oral Rare and Genetic Diseases of our hospital with the chief complaint of “discomfort for over seven months following the extraction of the teeth in the left mandibular region.” Based on her clinical manifestations and imaging findings, she was diagnosed with RO in the left mandible and with hypodontia of permanent teeth 12 and 34. A treatment plan was formulated, and long-term follow-up was conducted. The current radiographic images were compared with previous imaging data to summarize the developmental changes in her teeth, and a comparative analysis was also performed with the literature to identify similarities and differences with previously reported RO dental characteristics.
Results:
During the follow-up period, the patient's symptoms did not worsen, and a conservative observation approach was adopted; the treatment plan was decided after the eruption of the affected teeth. By comparing and analyzing imaging data from three ages (4.5, 8.5, and 9 years old), it was determined that the deciduous and permanent teeth in the left mandible of this patient exhibited typical “ghost” radiographic features, alongside hypodontia of teeth 12 and 34, as well as the delayed development of tooth 35. A literature review and analysis indicated that RO manifests clinical characteristics such as delayed tooth eruption, reduced tooth size, and yellow crowns, along with typical “ghost” radiographic appearances. Treatment requires a personalized approach based on the patient’s specific condition. To date, only five cases of RO patients with hypodontia have been reported, while the delayed development of permanent tooth buds has not yet been documented.
Conclusion
For patients with RO, dynamic imaging evaluation plays a critical role in early diagnosis. RO is associated with hypodontia and delayed tooth germ development. Long-term follow-up and personalized treatment plans are the key to RO treatment.

Chronic obstructive pulmonary disease (COPD) is a common clinical chronic airway disease with high morbidity, high mortality, a heavy disease burden, and complex mechanisms that have not been fully elucidated. Clinical problems promote the continuous progress of basic research. The establishment and evaluation of animal models is an important way to delve into the pathogenesis and treatment strategies of COPD. On the basis of the etiology, pathogenesis, diagnostic criteria, and syndrome differentiation of COPD in traditional Chinese medicine (TCM) and Western medicine, this paper summarizes the establishment methods and characteristics of existing animal models of COPD and analyzes the fitting degree of the models with the disease characteristics in Western medicine and syndrome characteristics in TCM. The results showed that the animal models of COPD in Western medicine were mainly induced by single factors and compound factors, and the model with the highest fitting degree was established by cigarette smoke combined with lipopolysaccharide and hormone. The model showed a fitting degree of 84% with the disease characteristics in Western medicine and 70% with the syndrome characteristics in TCM, being consistent with the clinical characteristics of COPD induced by multiple factors. Most of the animal models of COPD in TCM were established on the basis of disease models and combined with TCM etiology and pathogenesis characteristics, and prepared by syndrome differentiation. Among them, the model of accumulation of cold and water retention in lung had the highest fitting degree of 92% with the TCM diagnostic criteria. The models of phlegm-heat obstructing lung and phlegm-stasis obstructing lung had the fitting degree of 94% with clinical manifestations in Western medicine and the highest fitting degree with the diagnostic criteria in Western medicine. Different animal models of COPD have their own advantages and disadvantages, and most of them simply replicate the manifestations of COPD at a certain stage, failing to reflect the multiple causes and the dynamic changes of TCM etiology and pathogenesis. Moreover, the syndromes of these models fail to match the clinical syndromes in TCM. Therefore, establishing the animal models reflecting clinical characteristics of COPD in TCM and Western medicine and improving the model evaluation criteria are important contents to promote the overall development of integrated traditional Chinese and western medicine for COPD.

OBJECTIVE To systematically evaluate the efficacy and safety of different chemotherapy combination regimens for first-line treatment of metastatic colorectal cancer (mCRC). METHODS PubMed, Cochrane Library, Embase and Web of Science were electronically searched to collect randomized controlled clinical trial (RCT) on first-line treatment for mCRC from January 1, 2000 to February 16, 2025. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Network meta-analysis was performed by using R4.4.3 and Stata 17.0 software. RESULTS A total of 28 RCTs, involving 16 intervention measures, were included. In terms of prolonging progression-free survival (PFS) and overall survival (OS), FOLFOX (5-fluorouracil+oxaliplatin+calcium folinate regimen)+cetuximab had the highest probability of ranking first. In terms of improving objective response rate (ORR), FOLFOXIRI (5-fluorouracil+oxaliplatin+irinotecan+calcium folinate regimen)+ bevacizumab and FOLFOX+bevacizumab+nivolumab had the highest probability of ranking first; in terms of the incidence of grade 3 or higher adverse reactions, FOLFOXIRI+panitumumab had the highest probability of ranking first; in subgroup analysis of KRAS wild-type patients, FOLFIRI (5-fluorouracil+irinotecan+calcium folinate regimen)+panitumumab and FOLFIRI+bevacizumab had the highest probability of ranking first in terms of prolonging PFS and OS, respectively; in terms of ORR, FOLFOXIRI+ cetuximab had the highest probability of ranking first. CONCLUSIONS In first-line treatment for mCRC, FOLFOX combined with targeted therapy has advantages in terms of efficacy and safety. However, individualized treatment strategies should be formulated based on the KRAS gene status and tumor location of patients.

Objective To investigate the effects of cucurbitacin B (CucB) on alleviating skin lesions and inflammation in psoriasis mice via the cGAS-STING signaling pathway. Methods The expression of genes associated with the cGAS-STING signaling pathway in psoriatic lesions and non-lesional skin was analyzed, and hallmark gene set enrichment analysis was performed. The cytotoxicity of CucB on BMDMs was evaluated using the CCK-8 assay. The expression levels of genes and proteins related to the cGAS-STING signaling pathway, along with the secretion of inflammatory cytokines, were measured at different concentrations of CucB using quantitative PCR, Western blotting, and ELISA. Imiquimod-induced psoriasis BALB/c mice were divided into four groups: normal group, model group, low-dose CucB group [0.1 mg/ (kg.d)], and high-dose CucB group [0.4 mg/ (kg.d)], with five mice per group. PASI scoring was performed to assess the severity of psoriasis after 6 days of treatment, and HE staining was conducted to observe pathological damage. Meanwhile, the mRNA levels of inflammatory cytokines and their secretion were detected by qPCR and ELISA. Results Most cGAS-STING signaling-related genes were upregulated in lesional skin of psoriasis patients, and the hallmark gene set enrichment analysis revealed that the most significantly upregulated genes were primarily associated with immune response signaling pathways. CucB inhibited dsDNA-induced phosphorylation of interferon regulatory factor 3 (IRF3) and STING proteins in both bone-marrow derived macrophages(BMDMs) and THP-1 cells. CucB also suppressed dsDNA-induced mRNA expression of IFNB1, TNF, IFIT1, CXCL10, ISG15, and reduced the secretion of cytokines such as IFN-β, IL-1β, and TNF-α in THP-1 cells. In the imiquimod-induced psoriasis mouse model, CucB treatment reduced psoriatic symptoms, alleviated skin lesions, and attenuated inflammation. ELISA and qPCR results showed that CucB significantly reduced serum secretion levels of IL-6, TNF-α, and IL-1β, as well as the mRNA levels of IL23A, IL1B, IL6, TNF, and IFNB1. Conclusion CucB inhibits cytoplasmic DNA-induced activationc of the GAS-STING pathway. CucB significantly attenuates skin lesions and inflammation in IMQ-induced psoriatic mice, and the potential molecular mechanism may be related to the down-regulation of the cGAS-STING pathway.

Chronic glomerulonephritis (CGN) is a common clinical chronic glomerular disease caused by autoimmune reaction, the pathogenesis of which is complex and has not been fully elucidated. There is no specific treatment method in modern medicine. The establishment of an animal model of CGN in accordance with its characteristics in western medicine and traditional Chinese medicine will help to reveal the pathogenesis of CGN, rate drugs, and improve the treatment plan. Based on the clinical diagnostic criteria of CGN, the paper establishes the syndrome differentiation criteria of CGN for Chinese and western medicine. Through summarizing the literature on animal models of CGN and making a further analysis, it is found that the CGN models are mainly modeled using rats with the methods of single-factor induction or two-factor induction, and the main manifestation of the disease characteristics is nephritis-related symptoms. The single-factor-induced or two-factor-induced CGN rat models have a high fitting degree with the clinical characteristics in western medicine, but the fitting degree is insufficient with the clinical characteristics in traditional Chinese medicine. In addition, the CGN models with syndromes of traditional Chinese medicine are dominated by Qi deficiency in the spleen and kidney and Qi deficiency in the lung and kidney, while models for Yang deficiency in the spleen and kidney, Yin deficiency in the liver and kidney, and deficiency of both Qi and Yin are slightly insufficient. Therefore, it is important to prepare a new and improved animal model of CGN, so that a preclinical model can be provided for the exploration of the pathogenesis of CGN in western medicine and traditional Chinese medicine and its therapeutic research.
