To analyze potential adverse drug events(ADEs) associated with ustekinumab and upadacitinib in the treatment of inflammatory bowel disease(IBD) based on an international authoritative database, thereby providing evidence for clinical medication safety. Data were extracted from the Food and Drug Administration Adverse Event Reporting System(FAERS) database using OpenVigil 2.1. ADE reports were collected for ustekinumab(from Q3 2017 to Q1 2025) and upadacitinib(from Q3 2019 to Q1 2025), where each drug was identified as the primary suspected medication for IBD. Signal detection and statistical analysis were performed using the reporting odds ratio(ROR) and proportional reporting ratio(PRR) methods. A total of 3648 ADE reports for ustekinumab and 3812 for upadacitinib, with each as the primary suspected drug in IBD treatment, were retrieved. Using the ROR-PRR combined detection method, relevant ADE signals were identified. High-frequency ADEs associated with ustekinumab included hypersensitivity reactions, various infections, and brain fog, while those associated with upadacitinib included acne, flatulence, and herpes zoster. System organ class(SOC) analysis of positive signals indicated that both drugs commonly caused ADEs in categories such as Infections and infestations, Gastrointestinal disorders, Nervous system disorders, Skin and subcutaneous tissue disorders, and Respiratory, thoracic, and mediastinal disorders. Among these, Infections and infestations were the most frequent SOC, involving preferred terms such as Escherichia sepsis and Pneumococcal pneumonia. Ustekinumab and upadacitinib exhibit distinct safety profiles in the treatment of IBD. In addition to known ADEs described in the prescribing information, ustekinumab requires close monitoring for hypersensitivity reactions, opportunistic infections, and potential neurological risks. For upadacitinib, attention should be paid to risks of acne, herpes zoster, hypercholesterolemia, and thrombotic events. These findings provide important safety information to support individualized clinical decision-making in IBD management.

Occupational contact dermatitis (OCD) is an occupational inflammatory skin disease. According to its pathogenesis, it can be divided into irritant contact dermatitis and allergic contact dermatitis. This review introduced the high-risk occupations of OCD, its incidence, common irritants and allergens, and corresponding treatments. Agriculture workers, construction workers, production workers, hairdressers, and medical workers are high-risk occupations of OCD who should be paid attention to.

Objective To investigate the association of transforming growth factor (TGF) gene rs1800469 (TGF1-509C/T) and rs1982073 (TGF1+869T/C) single nucleotide polymorphisms (SNP) with susceptibility of lung cancer. Methods The case group consisted of 193 histologically diagnosed lung cancer patients, and control group of 211 controls were selected from cancer-free patients at the same time. The single nucleotide polymorphisms of rs1800469 (TGF1-509C/T) and rs1982073(TGF1+869T/C) were analyzed by real-time fluorescent quantitative reverse transcription polymerase chain reaction method. The demographic characteristics, correlated risk factors of exposure and SNP between 2 groups were compared. Results The genotype distribution frequency of TGF1+869T/C and TGF1-509C/T in control group was accorded with Hardy-Weinberg law (P>0.05). The TT, TC and CC genotype distribution frequency in TGF1+869T/C in case group were 16.1%(31/193), 55.4%(107/193) and 28.5%(55/193), while these in control group were 22.3% (47/211), 50.2% (106/211) and 27.5% (58/211), and there were no statistical differences (P>0.05). The TT, TC and CC genotype distribution frequency in TGF1-509C/T in case group were 28.0%(54/193), 56.0%(108/193) and 16.1%(31/193), while these in control group were 27.0% (57/211), 51.2% (108/211) and 21.8% (46/211), and there were no statistical differences (P>0.05). The allele in rs1800469 (TGF1-509C/T) and rs1982073 (TGF1+869T/C) showed no association with lung cancer (P>0.05). Conclusions TGF gene SNP may not be associated with susceptibility to lung cancer in Han Chinese in North China.
