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.

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.

ObjectiveTo observe the clinical efficacy and safety of Guben Quyu Jiedu prescription in treating nocturnal hypoxemia of chronic obstructive pulmonary disease (COPD) combined with Obstructive sleep apnea hypopnea syndrome ( OSAHS ) (deficiency of lung, spleen and kidney with blood stasis and toxicity). MethodsThe paper used a forward-looking, random double-blind, placebo-controlled design method to select 96 patients with COPD combined with OSAHS, and their traditional Chinese medicines (TCM) syndrome differentiation was deficiency of lung, spleen and kidney with blood stasis and toxicity. These patients were randomly divided into the observation group and the control group, with 48 cases in each group. Based on conventional Western medicine treatment, the observation group was treated with Guben Quyu Jiedu prescription and the control group was treated with traditional Chinese medicine placebo. Both courses of treatment were 90 days. Then the paper compared the changes in minimum pulse oxygen saturation (SpO2) during the night, apnea index (AHI), OSAHS efficacy evaluation, TCM syndrome efficacy evaluation, and TCM symptom score before and after treatment between the two groups. ResultsThere were 5 withdrawals in the observation group and 8 withdrawals in the control group, so 43 cases in the observation group and 40 cases in the control group completed the trial. Compared with the condition before treatment, the minimum SpO2 during the night and AHI in the observation group were significantly improved at night (P<0.01) and were better than those in the control group (P<0.01). OSAHS efficacy in the observation group was better than in the control group (χ2=7.085, P<0.05). In terms of TCM syndrome efficacy, the total effective rate was 81.40% (35/43) in the observation group, significantly higher than that in the control group, which was 15.00% (6/40) (χ2=36.78, P<0.01). The TCM symptom scores of the two groups were improved compared with the condition before treatment, and the effect of the two groups was similar in the four main symptoms of snoring, choking, lethargy, and cough. However, the observation group was better than the control group in 10 details such as dizziness, headache, chest tightness, chest pain, wheezing, dry mouth, and thirst (P<0.05). ConclusionUsing Guben Quyu Jiedu prescription combined with conventional Western medicine can treat COPD combined with OSAHS hypoxemia at night (deficiency of lung, spleen and kidney with blood stasis and toxicity). In this way, the minimum pulse oxygen saturation (SpO2) of patients, the level of disease control, and the quality of life of patients can be improved, and the clinical symptoms can be relieved.

AIM: To analyze the clinical utility and value of the ultra-wide-field swept-source optical coherence tomography angiography(UWF-SS-OCTA)technique in changes of blood flow density and thickness in the central and peripheral regions of the retina and choroid in patients with nonproliferative diabetic retinopathy(NPDR)with or without diabetic kidney disease(DKD).METHODS: Cross-sectional study. Totally 50 cases(50 eyes)of diabetes mellitus(DM)that visited our hospital between June 2023 and June 2024 were included. They were divided into three groups: NPDR combined with DKD group(DKD group, n=20), NPDR without DKD group(NDKD group, n=20), and DM without retinopathy group(DM group, n=10, which served as control). In order to investigate the impact of DKD on ocular microangiopathy in NPDR patients, the retina and choroid within 24 mm×20 mm of the scan were separated into central and peripheral areas using the 3×3 nine-grid partition option that comes with UWF-SS-OCTA, and the parameters were then quantitatively assessed.RESULTS:The central and peripheral blood flow density of the choroidal capillary layer(CCP)was statistically significant between the DM group and the DKD group(t=3.93, P=0.0003; t=3.34, P=0.0016), and between the NDKD group and the DKD group(t=-3.06, P=0.003; t=-2.55, P=0.013), but there was no statistically significant difference between the DM group and the NDKD group(t=1.44, P=0.157; t=1.26, P=0.21). The mid-large choroidal vessel(MLCV)showed a progressive decline in central and peripheral blood flow density in the DM, NDKD, and DKD groups(F=13.74, 19.03, all P<0.0001). The DM, NDKD, and DKD groups saw a progressive decrease in central and peripheral choroidal thickness(CT; F=10.72, P=0.0001; F=13.12, P<0.001).CONCLUSION:CCP, MLCV, and CT can be used as visual indicators to identify impaired renal function in patients with NPDR. UWF-SS-OCTA can support the development of precise and noninvasive monitoring and treatment technology for diabetic ocular microangiopathy, while also offering a scientific foundation for the joint management of DR and DKD.
