Work serves as a critical means of obtaining resources, facilitating personal growth, realizing self-worth, and engaging in social interactions. However, work-related diseases pose significant threats to workers’ health and productivity, and impose considerable economic burdens. This article categorized work-related diseases into six major types, including musculoskeletal disorders, mental and behavioral disorders, cardiovascular and metabolic diseases, digestive system diseases, reproductive system diseases, and non-specific respiratory diseases, and summarized their risk factors, assessment methods, policy regulation, and prevention and control measures. Current research in this field predominantly relies on cross-sectional studies, which present limitations in causal inference and potential risks of bias. Future studies should expand sample sizes, optimize research designs, and establish multidimensional evaluation systems to comprehensively assess the health and economic impacts of work-related diseases. It is recommended to enhance the translation of research findings into practice, thereby providing a scientific basis for the occupational health protection system and promoting the well-being and sustainable development of the working population.

ObjectiveTo establish fingerprint profiles and a quantitative determination method for Lycii Cortex, providing a scientific basis for the formulation of quality standards for Lycii Cortex and its roasted products. MethodsHigh performance liquid chromatography(HPLC) was developed for the quantitative method for determining kukoamine B in Lycii Cortex and its roasted products on an Alphasil XD-C18 CH column(4.6 mm×250 mm, 5 μm). HPLC fingerprint profiles were established for 10 batches of Lycii Cortex and its roasted products, and ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used to identify the common peaks based on reference standards, literature and MS information. Quality evaluation indicators included yield of decoction pieces, appearance properties, content of kukoamine B, and fingerprint profiles. The temperature and time of the roasting process were investigated to select the optimal preparation process, which was then verified. Additionally, chemical pattern recognition was combined to assess the differences in the chemical composition of Lycii Cortex before and after roasting, as well as among samples from different origins. ResultsQuantitative analysis indicated that the contents of kukoamine B in Lycii Cortex and its roasted products were 0.35%-5.51% and 0.24%-4.15%, respectively. The transfer rate of kukoamine B was 58.6%-78.9% after roasting. The fingerprint profile analysis demonstrated that the method established in this study effectively separated kukoamine B from other components in the samples and distinctly differentiated it from its impurity peak, cis-N-caffeoylputrescine. The HPLC fingerprint profiles of Lycii Cortex and its roasted products showed high similarity(all above 0.95), with 7 common peaks identified and five common components, including kukoamine B, cis-N-caffeoylputrescine, N-coumaroyl tyramine, feruloyltyramine, and glucosyringic acid, confirmed. Process optimization confirmed that baking at 110 ℃ for 20 min was a stable and feasible method for roasting Lycii Cortex. Principal component analysis and cluster analysis showed that there was little difference in the chemical composition between raw and roasted Lycii Cortex, but the quality of Lycii Cortex from different origins differed greatly. ConclusionThis study successfully established the fingerprint profiles and a quantitative method for the effective component kukoamine B in Lycii Cortex and roasted Lycii Cortex. The qualitative and quantitative analyses clarified that the impact of the roasting process on the chemical composition of Lycii Cortex was less significant than the variations due to its geographical origin. The findings of this study offer a reference for the development of quality evaluation methods and the establishment of quality standards for Lycii Cortex and its processed products.

ObjectiveTo investigate the potential mechanism of the Jianpi Yishen Huatan Formula (健脾益肾化痰方,JPYSHF) in treating squamous cell lung cancer through the LncRNA ALAL-1/USP4/HDAC2 signaling pathway. MethodsForty Sprague-Dawley (SD) rats were randomly divided into a control group and high-, medium-, and low-dose JPYSHF group with 10 rats in each group. Rats in the JPYSHF groups were administered JPYSHF concentrated liquid at doses of 45, 30, and 15 g/(kg·d) via intragastric gavage, respectively, while the control group received 10 ml/(kg·d) of normal saline, once daily for 10 consecutive days before preparation of drug containing serum. Human lung squamous carcinoma SK-MES-1 cells were divided into a control group and low-, medium-, and high-dose JPYSHF-medicated serum groups. The control group was cultured with 10% saline-containing serum, while the JPYSHF groups were cultured with 10% low-, medium-, or high-dose medicated serum. After 48 hours of incubation, flow cytometry was used to detect apoptosis rates, and a cell scratch assay was performed to evaluate migration areas at 0 h and 24 h to calculate migration rate. Additional SK-MES-1 cells were divided into control serum, JPYSHF-medicated serum (low-, medium-, high-) dose, LncRNA-silenced group (transfected with ALAL-1 siRNA), USP4-inhibited group (treated with 35 μmol/L PR-619, a deubiquitinase inhibitor), and HDAC2-inhibited group (treated with 60 μmol/L Vorinostat). After 24 and 48 hours of culture, cell viability was assessed using the CCK-8 assay; LncRNA ALAL-1, USP4, and HDAC2 mRNA levels were quantified by qPCR after 24 hours; USP4 and HDAC2 protein levels were measured by Western Blot after 48 hours. ResultsCompared with the control serum group, the total apoptosis rate of cells in middle- and high-JPYSHF-medicated serum group significantly increased, and the cell migration rate of cells in the low-, middle- and high-JPYSHF-medicated serum group significantly decreased (P<0.05 or P<0.01). The cell migration rate of the low-, medium- and high-JPYSHF-medicated serum groups decreased with the increase of concentration in a concentration-dependent manner (P<0.05 or P<0.01). Compared with the control serum group at the same time, the cell viability at 24 h and 48 h significantly decreased in all groups (P<0.05 or P<0.01). Compared with the low-JPYSHF-medicated serum group at the same time, the cell viability at 24 h and 48 h also decreased in the high-JPYSHF-medicated serum group and the LncRNA silencing group (P<0.05). Compared with the control serum group, the expression of USP4 and HDAC2 mRNA reduced in the low- and medium-dose JPYSHF-medicated serum groups and the USP4 inhibitor group, and the expression of LncRNA ALAL-1, USP4 and HDAC2 mRNA reduced in the high-dose JPYSHF-medicated serum group and LncRNA-silencing group, and HDAC2 mRNA expression reduced in the HDAC2 inhibitor group. USP4 and HDAC2 protein levels were reduced in cells of all groups except for USP4 protein level in HDAC2 inhibitor group (P<0.05 or P<0.01). ConclusionJPYSHF-medicated serum inhibits proliferation and promotes apoptosis of human lung squamous carcinoma cells, and its mechanism of action may be related to its inhibition of the LncRNA ALAL-1/USP4/HDAC2 pathway, with best effect at a high concentration.

Major depressive disorder is a prevalent and debilitating mental disorder worldwide. Suicidal ideation and behavior represent a severe clinical manifestation closely associated with high mortality and disease burden. Current antidepressants have a delayed onset of action and fail to address the urgent need for rapid symptom relief in patients with major depressive disorder with suicidal ideation or behavior (MDSI). The glutamatergic antidepressant esketamine has demonstrated rapid antidepressant efficacy and a tolerable safety profile in patients with MDSI in multiple clinical trials, making it a promising therapeutic option. Esketamine is a non-selective, non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist. In 2023, the nasal spray formulation was approved in China for use in combination with oral antidepressants to alleviate depressive symptoms in adults with MDSI. This review summarizes the latest clinical research progress on esketamine nasal spray for MDSI, providing evidence-based guidance for psychiatrists in clinical decision-making.
