Background Occupational disease diagnosis appraisal is an appeal procedure initiated when a party disagrees with the occupational disease diagnosis conclusion. It is a legal procedure to safeguard the health rights of employees and the legitimate rights and interests of employers. Objective To analyze the data of occupational disease diagnosis appraisal in Shanghai, identify existing problems, and provide suggestions for improving. Methods Statistical analysis was conducted on basic situation, characteristics of workers and employers, disease classification, and consistency between diagnosis and appraisal conclusions of all occupational disease diagnosis appraisal cases from 2012 to 2024. All diagnosis conclusions were named in accordance with the Classified Catalogue of Occupational Diseases included employers were classified according to the Measures for the Statistical Classification of Large, Medium, Small and Micro Enterprises" and the Notice on Adjusting the Provisions for Classifying Enterprise Registration Types; industry classification followed the Industrial Classification for National Economic Activities (GB/T 4754-2017). Results From 2012 to 2024, a total of 260 cases of occupational diseases diagnosis appraisal were closed. The main diagnosis were 138 cases of ear, nose, throat, and oral diseases (53.1%), chemical poisoning (18.8%), and pneumoconiosis and other respiratory diseases (16.2%). The proportion of ear, nose, throat, and oral diseases gradually increased (2022 excluded). The incidence of annual municipal and provincial cases decreased by 76.3% and 85.0% respectively (2024 vs 2012). The consistency rate of conclusions between appraisal and diagnosis gradually increased. The total consistency rates between final appraisals and diagnostic conclusions were 81.5%, and 79.7%, 87.8%, 100.0%, 85.0% for ear, nose, throat, and oral diseases, chemical poisoning, and pneumoconiosis and other respiratory system diseases, respectively. Specifically, the consistency rates were 80.1% and 80.0% for noise-induced deafness and chronic benzene poisoning. In terms of inconsistency reasons, "inconsistent interpretation of standards and excessive discretion in standard application" accounted for 43.8%, followed by "failure to correctly apply standards" (31.3%) and and "discrepancies in occupational exposure history recognition" (15.6%). Conclusion The revisions and improvements of the legal system for occupational disease diagnosis appraisal have played a positive role in improving the consistency of conclusions between appraisal and diagnosis of occupational diseases in Shanghai. It is suggested to further strengthening the publicity and training of occupational disease diagnosis standards to improve the quality of occupational disease diagnosis.

Lung cancer is the most common malignant tumor of the respiratory system, and its pathogenesis is still not fully understood. Despite the significant clinical efficacy achieved through treatments such as surgery, radiotherapy, chemotherapy, targeted therapy, and immunotherapy, they still come with many complications and significant adverse reactions. In recent years, numerous basic and clinical studies have confirmed the effectiveness of Chinese medicine in treating lung cancer. Chinese medicine features synergistic regulation through its multiple components, targets, pathways, and approaches. Active monomeric constituents in Chinese medicine are diverse, and their mechanisms of action are intricate, making it challenging to fully understand the mechanisms by which Chinese medicine prevents and treats lung cancer. Therefore, there is an urgent need to approach Chinese medicine intervention in lung cancer from a modern medical perspective, exploring the mechanisms of Chinese medicine intervention in lung cancer at the molecular biology and network pharmacology levels. According to traditional Chinese medicine (TCM), the occurrence of lung cancer is predominantly attributed to factors such as deficiency of healthy Qi, presence of pathogenic factors, internal accumulation of heat-toxins, internal accumulation of phlegm-dampness, and Qi stagnation and blood stasis. Literature analysis reveals that Chinese medicine compound formulas for lung cancer predominantly include tonifying agents and heat-clearing and toxin-removing agents, such as Shashen Maidongtang, Xiaoyan prescription, and Feijinsheng prescription. The single herbs used mainly include heat-clearing, deficiency-tonifying, blood-activating, stasis-resolving, phlegm-resolving, cough-relieving, and asthma-calming categories. The use of Chinese medicine aligns with the TCM understanding of the etiology and pathogenesis of lung cancer. Studies have shown that TCM can regulate the expression of key molecules in lung cancer-related signaling pathways, such as the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt), nuclear factor-kappa B (NF-κB), Wnt/β-catenin, mitogen-activated protein kinase (MAPK), and Janus kinase/signal transducer and activator of transcription (JAK/STAT), thereby exerting effects such as reducing lung cancer cell activity, blocking the cell cycle, inhibiting proliferation and invasion of lung cancer cells, inducing apoptosis in lung cancer cells, promoting cell autophagy, and reversing drug resistance, and intervening in the progression of lung cancer. This study systematically summarized recent research progress on how Chinese medicine monomers or formulas regulated the aforementioned signaling pathways and key protein expression to exert anti-lung cancer effects, aiming to elucidate the mechanisms by which Chinese medicine intervenes in the progression of lung cancer and provide insights and theoretical basis for further research and clinical application of Chinese medicine in lung cancer intervention.

The complex barriers to drug delivery in the eye make it difficult for traditional ophthalmic preparations to reach pathological tissues in the posterior segment of the eye via ocular surface. Therefore, intravitreal drug injection has been widely used for treating posterior segment diseases, but this invasive approach to drug delivery has disadvantages such as short drug half-lives, repeated injections, and many complications. Ophthalmic nanodrug delivery systems, which can overcome ocular drug delivery barriers, enhance drug permeability, and improve drug bioavailability, now make it possible to efficiently deliver drugs to the posterior segment of the eye. However, the carrier materials utilized for nanomedicine delivery are inherently intricate, and substantial disparities exist among research findings, posing a hindrance to the subsequent advancement of pertinent drug formulations. Consequently, this review centers on the principal physiological obstacles encountered in ocular drug delivery, emphasizing the utilization of diverse nanomedicine delivery systems in posterior segment pathologies. It aims to delve into their research progress in posterior segment diseases and establish a safer, more effective therapeutic approach for treating these ocular conditions.

By sorting out the differences and connections between family doctor teams and specialized disease teams, role competency and mutual collaboration, and introducing the learning health system (LHS) mechanism, a comprehensive operating system for community general practice learning organizations based on LHS was constructed, focusing on five single disease types. The system includes a combination of general and specialized medicine that links three levels of medical institutions, thereby opening up the business cooperation process between professionals in different institutions, and establishing a sustainable collaboration mechanism. This allows medical institutions at three levels to continuously tap the potential of their disciplines, achieve their own ability growth and feel higher work value, and also bring better health solutions to residents, guided by the common goal of "health centered, patient centered".

The adulteration and counterfeiting of herbal ingredients in medicinal and food homology (MFH) have a serious impact on the quality of herbal materials, thereby endangering human health. Compared to pharmaceutical drugs, health products derived from traditional Chinese medicine (TCM) are more easily accessible and closely integrated into consumers' daily life. However, the authentication of the authenticity of TCM ingredients in MFH has not received sufficient attention. The lack of clear standards emphasizes the necessity of conducting systematic research in this area. This study utilized DNA barcoding technology, combining ITS2,
