Background Health literacy is closely related to mental health, and improving health literacy has been shown to promote mental well-being. However, whether occupational stress among workers in mining and manufacturing is associated with their occupational health literacy remains inconclusive. Objective To study the levels of occupational health literacy and occupational stress among workers in three industrial sectors (metal ores mining, metal smelting, and manufacture of non-metallic mineral products) in Gansu Province, and to analyze the correlation between them. Methods Between May and December 2024, a stratified cluster random sampling method was employed to survey workers from 73 large, medium, and small and micro sized enterprises across the aforementioned industries in Gansu Province. Participants’ occupational health literacy and occupational stress levels were assessed. The LASSO regression model was applied to identifykey factors influencing occupational stress, and subsequently a multilevel random intercept mixed-effects logistic model was used to study factors influencing occupational stress and to explore the relationship between occupational health literacy and occupational stress. Results A total of 3611 workers across the three industries were surveyed, among whom 1031 (28.55%) experienced occupational stress. Workers with adequate occupational health literacy—whether assessed in terms of overall literacy or specific dimensions—demonstrated a significantly lower prevalence of occupational stress compared to those without adequate literacy (P<0.05). Through the LASSO regression analysis, it was found that the factors closely related to occupational stress were dimension one (occupational health legal knowledge), dimension two (basic knowledge of occupational health protection), and dimension four (healthy working methods and behaviors) of occupational health literacy, gender, average monthly income, and night shifts. The results from the three-level random intercept mixed-effects logistic regression model indicated that dimensions one (OR=0.69, 95%CI: 0.58, 0.82), two (OR=0.71, 95%CI: 0.58, 0.87), and four (OR=0.81, 95%CI: 0.67, 0.98) of occupational health literacy were negatively correlated with the risk of occupational stress. Workers with an average monthly income of 3001–≤5000, 5001–≤7000, and ≥7001 yuan reported occupational stress risks that were 61% (OR=0.61, 95%CI: 0.45, 0.81), 56% (OR=0.56, 95%CI: 0.41, 0.78), and 36% (OR=0.36, 95%CI: 0.24, 0.53) of those with an average monthly income ≤3000 yuan, respectively. Male workers (OR=1.66, 95%CI: 1.32, 2.10) and those on night shifts (OR=2.29, 95%CI: 1.90, 2.76) had a higher risk of occupational stress. The random effects variance showed that the intraclass correlation coefficient was 0.12. Conclusion There is a negative correlation between occupational stress and occupational health literacy among workers in mining and manufacturing. Being male, having a low income, and working night shifts are risk factors affecting workers' occupational stress. It is recommended to focus on these groups of workers and incorporate occupational health literacy into workplace mental health promotion.

Qingzao Jiufeitang is a famous classical formula for treating lung injury caused by warm and dryness， included in the Catalogue of Ancient Famous Classical Formulas（The First Batch）. By systematically organizing ancient and modern literature on this formula， this study analyzed and verified the origin， medicinal composition， original plants and processing， dosage and decoction method， efficacy and application of this formula. According to the research， Qingzao Jiufeitang was first recorded in Yimen Falyu in the Qing dynasty， and its creation was mainly inspired by the Ming dynasty physician MIAO Xiyong's idea of the moisturizing drugs with sweet flavour and cold nature. Based on the 2020 edition of the Pharmacopoeia of the People's Republic of China（hereinafter referred to as the Chinese Pharmacopoeia） and the textual research results of modern scholars on traditional Chinese herbal medicines， the botanical sources and processing methods of the herbs in this formula are basically clarified. Among them， Mori Folium， Gypsum Fibrosum， Ginseng Radix et Rhizoma， Sesami Semen Nigrum， Asini Corii Colla， Ophiopogonis Radix and Eriobotryae Folium are consistent with the 2020 edition of the Chinese Pharmacopoeia. The primary source of Glycyrrhizae Radix et Rhizoma is the dried roots and rhizomes of Glycyrrhiza uralensis， family Leguminosae， while the primary source of Armeniacae Semen Amarum is the dried mature seeds of Prunus armeniaca， family Rosaceae. It is recommended to use Gypsum Ustum， stir-fried Sesami Semen Nigrum， stir-fried Armeniacae Semen Amarum， Asini Corii Colla bead， and honey-fried Eriobotryae Folium， and the rest of the raw products. According to the conversion of ancient and modern doses， the recommended dosages are 11.19 g for Mori Folium， 9.33 g for Gypsum Fibrosum， 3.73 g for Glycyrrhizae Radix et Rhizoma， 2.61 g for Ginseng Radix et Rhizoma， 3.73 g for Sesami Semen Nigrum， 4.48 g for Ophiopogonis Radix， 2.61 g for Armeniacae Semen Amarum， 3.73 g for Eriobotryae Folium. The decoction method is to add 300 mL of water， decoct it down to 180 mL， remove the residue， and then add 2.98 g of Asini Corii Colla into the decoction. Take it warm after meals， two to three times a day. Qingzao Jiufeitang has the effects of clearing dryness and moistening the lungs， nourishing Yin and invigorating Qi. In ancient times， it was mainly used to treat stagnation and depression of various Qi， as well as paralysis， asthma and vomiting. In modern clinical practice， it is mostly used to treat diseases in respiratory system， otolaryngology， skin system and digestive system caused by warm-dry impairing lung， deficiency of both Qi and Yin. The above research results can provide a reference for the later development of Qingzao Jiufeitang.

Cancer ranks as the second leading cause of death globally and has surpassed cardiovascular diseases to become the primary cause of mortality in developed countries. Cancer stem cells (CSCs), which play crucial roles in cancer recurrence, metastasis, and drug resistance, have attracted significant attention in targeted therapeutic strategies. Aptamers, with unique three-dimensional structures capable of specifically recognizing the surface markers of CSCs, show promising potential in targeted drug delivery systems. Compared with conventional antibodies, aptamers are praised for small molecular weights, low production costs, and easy chemical modification. This review systematically summarizes recent advances in aptamer research targeting the surface markers of CSCs, with particular emphasis on aptamer-drug conjugate systems targeting the markers including EpCAM, CD133, CD44, and ABCG2. Both in vitro cellular studies and in vivo animal models have demonstrated the definite anti-cancer efficacy of aptamer-based drug delivery systems, which are of great significance to develop novel therapeutic strategies and improving the therapeutic effects of CSC-targeted treatment. Thus, aptamer-based drug delivery system has broad application prospects in the field of precise cancer treatment.

OBJECTIVE Aimed at investigating whether reflux pharyngitis is an independent risk factor for the failure of type Ⅰ tympanoplasty for chronic otitis media.This is achieved by analyzing the relationship between the postoperative tympanic membrane healing in patients who underwent type Ⅰ tympanoplasty and pharyngolaryngeal reflux finding score(RFS).METHODS Patients who underwent type Ⅰ tympanoplasty in the Department of Otolaryngology Head and Neck Surgery,Nanshan People's Hospital,Shenzhen,China,from January 2023 to July 2024 were retrospectively included.All the patients received preoperative perfect nasal endoscopy,laryngoscopy,evaluation by the RFS questionnaire,preoperative otoscopy for tympanoplasty,pure tone hearing threshold,and temporal bone thin-layer CT examination.Postoperative otoscopic examination was performed to observe tympanic membrane healing and followed up for 3 months.The patients were divided into surgery success group and failure group based on the criterion of whether a complete tympanic membrane was formed by endoscopic examination within 3 months.The RFS scores of the two groups were statistically analyzed.RESULTS A total of 135 patients with an average age of 44.78 years(±12.22 years)took part in this study,with 60 males and 75 females included,and 68 left ears and 67 right ears involved.There were 120 patients in the surgery success group,and 15 patients in the failure group.Statistical analysis revealed that the RFS score of the patients in the tympanoplasty failure group was remarkably higher than that of the patients in the tympanoplasty success group.Moreover,there were significantly more cases with suspected reflux pharyngitis in the surgery failure group(P=0.007).Reflux-induced tympanic membrane lesion and reperforation mostly occurred in the central part of the tympanic membrane graft.CONCLUSION Reflux pharyngitis has been implicated with tympanoplasty failure,and thus may be a causative factor.Additionally,the RFS can be used to screen patients with chronic suppurative otitis media for suspected reflux pharyngitis.Findings from this work indicate that perioperative anti-reflux therapy,combined with dietary and lifestyle counselling for the patients who suffer from reflux pharyngitis and are about to undergo the tympanoplasty surgery may improve surgical success rate.

Sj?gren's syndrome(SS)is one of the common rheumatic diseases in clinical practice.Modern medicine commonly uses drugs such as artificial tears,saliva,glucocorticoids,immunosuppressants,and biologics to control the condition.Clinical practice has shown that in addition to modern medical basic treatment,the use of traditional Chinese medicine(TCM)can help improve the clinical efficacy of SS.According to the symptoms and signs of Sj?gren's syndrome in TCM,it is classified as"dryness and obstruction",and the core pathogenesis of the disease is spleen deficiency and deficiency of body fluids.Subsequently,toxic and pathogenic factors gather,leading to the decline of internal organs.The initial causes are spleen damage,unstable barrier,and invasion of pathogenic factors.The core link is spleen dysfunction,insufficient body fluid,and dryness arising from it.Spleen deficiency generates evil,obstruction of qi,and lack of body fluids are the root causes of illness.The main treatment method is the"spleen strengthening method",which treats spleen deficiency,dampness and stagnation,and the body fluid is not distributed.The treatment focuses on strengthening the spleen and qi,supplementing the lungs and generating fluids.Spleen deficiency leads to loss of vitality,blood stasis obstructs blood vessels,and the treatment is to strengthen the spleen,soothe the liver,remove blood stasis,and unblock the orifices.The spleen yang is not vigorous,and qi transformation is impaired.The treatment is to invigorate the spleen and warm the stomach,promote yang circulation,and promote diuresis.

Objective To investigate the risk factor for adverse events(AEs)after non-sedated esophagogastroduodenoscopy(EGD).Methods The data on clinical manifestations,adverse events after non-sedated EGD and common risk factors were collected and retrospectively analyzed with statistical methods in patients who underwent non-sedated EGD from May 2018 to June 2019.These patients were divided into AEs group and non-AEs group.Results Of 2 384 patients,57.67%(1 375/2 384)presented with nausea,12.79%(305/2 384)vomiting,and 5.79%(138/2 384)presented with pharyngalgia.Multivariate Logistic regression analysis was performed.Advanced age(≥65 years old)(OR=0.683,95%CI:0.506-0.921)was protective factors for nausea after non-sedated EGD.Hypertension(OR=1.361,95%CI:1.026-1.806),overweight(OR=1.399,95%CI:1.154-1.695),obesity(OR=2.594,95%CI:1.760-3.823)and inspection duration>15 min(OR=3.107,95%CI:2.296-4.206)were independent risk factors for nausea after non-sedated EGD.Advanced age(OR=0.393,95%CI:0.221-0.699)and imported equipment(OR=0.697,95%CI:0.546-0.890)were protective factors for vomiting after non-sedated EGD.Moreover,inspection duration>15 min(OR=1.641,95%CI:1.008-2.699)was independent risk factors for vomiting after non-sedated EGD.There was no difference in success rate of non-sedated EGD between two groups(P<0.05).Conclusion Hypertension,overweight and obesity were independent risk factors for nausea after non-sedated EGD.The advanced age and imported equipment were protective factors for vomiting after non-sedated EGD.In addition,inspection duration over 15 min is a risk factor for AEs such as nausea and vomiting after nonsedative EGD.Whether AEs occurred or not is non-related to success rate of non-sedated EGD.

Gastric cancer is a common clinical tumor,and its incidence and mortality rates rank among the top of malignant tumors.Helicobacter pylori(Hp)is an important carcinogenic factor for gastric cancer.Studies have found that in addition to Hp,other microorganisms in the stomach also play a key role in the progression of gastric cancer.The composition and diversity of the gastric microbiota vary significantly under different gastric disease conditions,which may affect the progression of gastric cancer.Hp can induce gastric epithelial inflammation and oxidative stress through various virulence factors,thereby promoting the occurrence of gastric cancer.Non-Hp microorganisms can be involved in the process of gastric cancer through pathways such as metabolic changes and immune regulation.In recent years,with the development of high-throughput sequencing technology,the complexity of gastric microbiota has gradually been revealed,which provides new insights for the early warning and intervention of gastric cancer.This article comprehensively review the role of gastric microbiota in the progression of gastric cancer.

Purpose To compare the clinical and cardiovascular magnetic resonance(CMR)characteristics of hypertrophic cardiomyopathy(HCM)with and without diabetes mellitus,and to investigate the effect of diabetes mellitus on left ventricular remodeling in HCM patients.Materials and Methods A total of 96 HCM patients diagnosed with CMR in Chengdu Fifth People's Hospital from January 2021 to March 2023,retrospectively.They were divided into HCM with diabetes mellitus group(n=22)and HCM without diabetes mellitus group(n=74)according to whether they had diabetes mellitus.The clinical baseline and CMR data of HCM patients were analyzed,and left ventricular function and strain were compared between the two groups.Results The HCM group with diabetes mellitus was observed to have a significantly higher left ventricular mass index compared to HCM without diabetes mellitus group[(1.33±0.50)g/ml vs.(1.10±0.23)g/ml;t=3.002,P=0.003],along with a significantly lower left ventricular global circumferential strain[-19.69(-21.82,-17.06)%vs.-16.33(-20.84,-13.86)%;Z=543.000,P<0.05]and global longitudinal strain[(-8.69±3.94)%vs.(-10.74±3.62)%;t=2.227,P<0.05)].Furthermore,diabetes mellitus was identified as an independent factor associated with an increased left ventricular mass index(β=0.330,P<0.05)by multivariate linear regression analysis.Conclusion In patients with HCM,diabetes mellitus is independently associated with left ventricular remodeling.The global circumferential strain and longitudinal strain of HCM patients with diabetes mellitus decreases significantly,suggesting that diabetes mellitus has a significant impact on left ventricular strain in HCM patients.
