Objective:
To explore the related influencing factors of high frequency hearing loss (HFHL) in workers exposed to noise and establish a prediction nomogram for HFHL.
Methods:
A total of 822 workers exposed to noise from 46 enterprises were included. A questionnaire survey and a pure-tone hearing test were conducted for the workers. The data of noise level of the workers exposed was also collected. After single factor analysis of related influencing factors, the multivariate Logistic regression analysis was performed to identify the final independent influencing factors of HFHL. Finally, a nomogram model was established by R software to achieve individual prediction of HFHL.
Results:
Among the 822 workers exposed to noise, 166 (20.2%) workers had HFHL. In multivariate Logistic regression analysis, increasing age, men, increasing wearing earphone time, less wearing earplugs, and high noise level were the independent risk factors for HFHL. The C-index of the nomogram model for predicting HFHL was 0.834 (95%

Pharmaceutical excipients, as an indispensable part of drug preparation, play crucial roles as drug carriers, improving drug release, ensuring drug stability, and enhancing patient compliance. Traditional Chinese Medicine (TCM) boasts a rich developmental history. With the modernization of technology, the deep integration of pharmacy, chemistry, and materials science has provided broader opportunities for innovative research in TCM. Simultaneously, the demand for high-quality excipients has become increasingly critical.This paper aims to review current research and applications of excipients in TCM preparations, including pre-mixed and co-processed excipients, modified excipients, and the unification of drugs and excipients, such as flavoring agents, fillers, penetration enhancers, and delivery systems. A meticulous synthesis and analysis of existing research aims to provide a reference for selecting excipients in TCM preparations, stimulate innovation in excipient development for TCM, and advocate for the development of personalized excipients.

Objective:To summarize the characteristics of neuralgia in Fabry disease and explore the effects of genders and alpha-galactosidase A (GLA) gene mutation types on neuralgia.Methods:Questionnaires and Brief Pain Inventory evaluations were conducted on the recruited patients diagnosed as Fabry disease in Department of Neurology, Peking University First Hospital from January 2001 to April 2020. The characteristics of the neuralgia were summarized, and the portrait of neuralgia between male and female patients, and the patient groups carrying truncated mutations and non-truncated mutations of GLA gene was compared.Results:A total of 93 patients with Fabry disease were enrolled. The incidence of neuralgia was 91.4% (85/93),and the average onset age of pain was 9 years. The average remission age was 20 years with the remission incidence of 22.8% (18/79). Pain attack on extremities [96.5%(82/85)] was the most common form. The neuralgia relieving rate of male patients [17.5%(11/63)] was lower than that of females (7/16, χ2=5.01, P=0.025).Brief Pain Inventory scores showed that the degree of most severe pain attack within 24 hours of male patients (4.16±3.20) was higher than that of females (2.07±2.02, t=3.03, P=0.004),and the impact of pain on daily life [male 4 (7) vs female 0 (4), Z=-2.33, P=0.020], walking ability [male 5 (8) vs female 0 (2), Z=-2.87, P=0.004], daily work [male 5 (8) vs female 0 (2), Z=-3.10, P=0.002], relationship [male 2 (6) vs female 0 (3), Z=-2.67, P=0.008] and interests [male 4 (8) vs female 0 (3), Z=-2.81, P=0.005] of male patients was also higher than female patients. The truncated mutation group [1 (2)] only showed higher score on the current pain level than the non-truncated mutation group [0(0), Z=-2.89, P=0.003]. Conclusions:The neuralgia in Chinese patients with Fabry disease showed high incidence and early onset. Male patients presented more severe pain than female which led to a greater impact on life, while the type of GLA gene mutation had less impact on neuralgia.
