Objective To analyze the monitoring results of occupational hazard factors (OHF) in the workplace of key industries in Shaoguan City from 2021 to 2024. Methods A total of 486 enterprises of key industries in Shaoguan City, selected from the "Occupational Diseases Hazardous Items Reporting System" and the "Guangdong Provincial Occupational Health Quality Control Platform" from 2021 to 2024, were used as the research subjects. Data on the declaration of occupational hazard projects, the exposure to OHF and the occupational medical examinations for workers, the usage of protective equipment and the setup of protection facilities in enterprises, and the monitoring results of OHF were analyzed. Results From 2021 to 2024, a total of 486 enterprises of key industries in Shaoguan City were monitored, and the detection rate of OHF exceeding national standard was 57.0%. The exceedance rates in medium/large enterprises and small/micro enterprises were 67.1% and 55.0%, respectively. A total of 51 771 worker-exposures to OHF were recorded, with an exposure rate of 55.8%. Training coverage for enterprise managers, occupational health personnel, and workers were 96.7%, 97.1%, and 98.7%, respectively. Abnormal rates in occupational medical examinations were 3.3%, 0.2%, and 0.8% among workers exposed to noise, dust, and chemical factors, respectively. Provision rates of dust respirators, chemical respirators, hearing protection devices (earplugs and earmuffs) were 93.2%, 85.4% and 86.8%, respectively, with wearing compliance rates of 98.7%, 98.8% and 97.1%. Installation rates of dust control, chemical hazard control, and noise control facilities were 97.2%, 90.3%, and 69.9%, respectively, and all facilities were 100.0% effective. Exceedance rates for OHF and noise increased annually (all P<0.05), whereas those for dust and chemical factors decreased (all P<0.05). The exceedance rates of work position from high to low were dust (18.1%), noise (17.1%) and chemical factors (6.4%). Lead-related position had the highest exceedance rate (31.9%). Industries with higher exceedance rates included metal products manufacturing (27.3%), ferrous metal smelting and rolling (24.1%), and non-metallic mineral products manufacturing (23.7%). Conclusion Workplaces in key industries of Shaoguan City face relatively high risks of occupational hazards. It is essential to focus on noise management, with efforts to strengthen occupational health supervision and guidance for small/micro enterprises as well as industries with severe occupational hazards, promoting the standardization of occupational health management.

Patients with lung cancer experience a heavy symptom burden during the perioperative period, which seriously affects their recovery and quality of life. Traditional symptom management models rely mainly on scheduled ward rounds during hospitalization and outpatient follow-up after discharge. However, they have limitations such as delayed symptom recognition, lack of post-discharge monitoring, and non-quantitative symptom assessment, which often lead to delayed interventions and low patient satisfaction. In recent years, the symptom management model based on electronic patient-reported outcomes (ePRO) has been increasingly valued in clinical practice. Existing high-level evidence from both domestic and international studies indicates that, through proactive monitoring, real-time alerts, and remote interventions, this model enables dynamic and continuous symptom management and helps improve patient recovery and healthcare experience. As a supplement to routine medical care, the ePRO-based symptom management model aims to enhance the quality of care rather than replace existing medical processes. To promote the standardized application of this model in perioperative lung cancer care, this consensus integrates domestic and international evidence. After multiple rounds of voting by more than 50 experts, it formulates 12 consensus statements covering the three core components, symptom monitoring, alerting, and intervention, to provide scientific and practical recommendations for clinical practice.

Transmissible gastroenteritis(TGE)is a highly contagious gastrointestinal disease of pigs caused by the transmissible gastroenteritis virus(TGEV).It results in severe diarrhea and high mortality in suckling piglets.As no specific treatment available,vaccination is considered to be one of the most cost-effective measures for preventing and controlling TGE.However,the immune protection provided by vaccines based on traditional TGEV strains is becoming inadequate due to the continuous emergence of strong and new strains of the virus,which poses a serious threat to the pig industry's health and development.Therefore,the development of new vaccines with im-proved efficiency and broad-spectrum coverage is urgently needed.This paper aims to summarize the pathogenic structural characteristics of TGEV,discuss the latest advancements in TGEV vac-cine research and development,and propose future strategies for the development of highly effec-tive TGEV vaccines.The findings of this paper can serve as a valuable reference for effectively pre-venting and controlling TGE in clinical practice.

The postoperative symptom burden in patients with lung cancer is severe and adversely impairs their quality of life. Symptom management is the cornerstone of medical care. Patient-reported outcome (PRO)-based symptom management is being increasingly recognized as the best "patient-centered care" model in clinical practice. However, the precise implementation of this model in patients undergoing lung cancer surgery is hindered by the lack of a lung cancer surgery-specific scale, implementation standards, clinical application parameters and high-quality researches. The use of a precise and simple PRO scale and an electronic PRO platform may greatly improve the feasibility of implementing this model. Currently, the application of PRO-based symptom management in lung cancer surgery is still being explored and needs to be improved in clinical research and practice.

Objective:To investigate whether the nutrition support team (NST) benefits esophageal carcinoma (EC) patients who are concurrently undergoing chemoradiotherapy. Methods: Between June 2012 and December 2013, 40 EC patients undergoing chemoradiotherapy were divided into the NST group and routine treatment (RT) group, with 20 patients in each group. At the end of chemoradiotherapy, the nutritional status, incidence of complications, and completion rates of radiotherapy were evaluated. The length of hospital stay (LOS) and cost were also compared between the two groups. Results:The nutrition and blood parameter values of the NST group were better (P<0.05) than those of the RT group. The incidence of complications was lower in the NST group (P<0.05) than that in the RT group. In addition, all patients in the NST group achieved the treatment plan, whereas five of the patients in the RT group interrupted or delayed the plan (P<0.05). The average LOS decreased by 3.8 d (P<0.05), and the hospitalization costs were reduced to 6300 RMB person-times (P>0.05) for the patients of the NST group. Conclusion: NST could maintain the nutritional status and improve the treatment compliance and tolerance of EC patients undergoing chemoradiotherapy, thereby shortening the LOS time and reducing the costs.

We studied immune modulation and antioxidant effects of wheat peptides on immunosuppressed mice. Mice were administrated with wheat peptides orally for 10 days and treated with cyclophosphamide at the 8th day. The indexes including serum hemolysin, plaque forming cells, spleen cells proliferation, liver antioxidant enzymes activties, malondialdehyde (MDA), scavenging serum 2,2-Diphenyl-1-picrylhydrazyl and *OH and macrophage phagocytic ability in vitro were measured to assess the immune functions and antioxidation abilities. In vivo study shows that cyclophosphamide significantly decreases serum hemolysin (HC50) and phagocytic function of macrophages. Simultaneously, liver superoxide dismutase, catalase activity and total oxidation capacity were decreased and malondialdehyde was increased. Wheat peptides could recover HC50 and spleen cell proliferation when orally administrated. Furthermore, they could also enhance serum 2,2-Diphenyl-1-picrylhydrazyl and *OH scavenging. In conclusion, wheat peptides can help body resist the stress related disorders in immune and antioxidant system.
