1.Causal relationship between Parkinson disease and the risk of mental illness: A two-sample Mendelian randomization study
Journal of Apoplexy and Nervous Diseases 2026;43(2):145-149
Objective Observational studies have shown an association between Parkinson disease (PD) and mental illness, but further studies are needed to explore the causal relationship between them. This study aims to investigate such causal relationship using the method of two-sample Mendelian randomization (MR). Methods Related data were extracted from GWAS, and summary statistics associated with PD, depression, sleep disorders, and anxiety phenotype-variants were obtained. Single nucleotide polymorphisms (SNPs) for PD were selected as instrumental variables, and MR-PRESSO was used to exclude outliers. Inverse variance weighting was used as the main method to assess causal effect estimates, and MR Egger, weighted median, simple mode, and weighted mode were used to verify the robustness of the findings. A sensitivity analysis was used to validate the reliability of the results, including the Cochran Q test, the MR-Egger intercept test, funnel plots, and the leave-one-out method. Results A total of 21 SNPs associated with PD were identified. The MR analysis showed that PD had a causal relationship with depression (OR=0.974,95%CI 0.934‒1.015, P=0.210), sleep disorders (OR=1.056, 95%CI 0.970-1.149, P=0.211), and anxiety (OR=0.998, 95%CI 0.996‒1.001, P=0.118), with no statistical significance. Different MR analyses and sensitivity analyses showed that PD did not directly contribute to the development of mental illness. Conclusion There is no direct causal relationship between PD and depression/sleep disorders/anxiety. In clinical practice, healthcare professionals should pay attention to the mental health of patients with PD. Randomized controlled studies should be conducted in the future to further validate the results of this study.

As a key treatment method for end-stage liver diseases, long-term efficacy of liver transplantation is limited by rejection and serious complications such as liver and kidney toxicity, infection risks and tumor recurrence caused by immunosuppressive drugs. In recent years, nanotechnology, with its targeted delivery capabilities and spatio-temporal controlled release characteristics, has demonstrated great potential in precisely regulating immune responses. This article systematically reviews the multi-level application strategies and mechanisms of nanomedicine in the immunoreprogramming of liver transplantation, covering innate immunoreprogramming (phenotypic transformation of Kupffer cells or macrophages, inhibition of inflammasomes and mitochondrial repair), adaptive immune remodeling (targeted regulation of dendritic cells, gene silencing vectors and reprogramming of T cell functions), and elaborates on the strategies for coordinated regulation of the microenvironment. The article also focuses on the targeted application of liver sinusoidal endothelial cells. In response to clinical translation bottlenecks, innovative solutions such as the design of degradable polymer carriers, the construction of intelligent response systems and the optimization of large-scale production pathways are proposed, providing theoretical support and practical directions for achieving the paradigm shift from "global immunosuppression" to "precise immune tolerance".

The classic formula Mulisan is the 45th of the 93 formulas in the Catalogue of Ancient Classic Formulas (second batch) of Han medicine published by the National Administration of Traditional Chinese Medicine. It consists of Ostreae Concha, Astragali Radix, Ephedrae Radix et Rhizoma, and wheat, with the effect of replenishing qi and stopping sweating. It is a common formula in the clinical treatment with traditional Chinese medicine. This study analyzes the historical evolution, composition, dosage, original plants and their processing methods, decocting method, efficacy, indications, and modern clinical application of Mulisan by tracing, comparative analysis, and bibliometric methods. The results showed that Mulisan firstly appeared in the Pulse Classic written by WANG Shuhe in the Western Jin Dynasty. The formulation idea can be traced back to the Important Prescriptions Worth a Thousand Gold for Emergency in the Tang Dynasty. The herb composition, dosage, efficacy, and indications of Mulisan were first recorded in the Treatise on Diseases, Patterns, and formulas Related to Unification of the Three Etiologies in the Southern Song dynasty. In terms of original plants and their processing methods, Ostreae Concha is the shell of Ostrea rivularis, which should be calcined before use. Astragali Radix and Ephedrae Radix et Rhizoma are the dried roots of Astragalus membranaceus var. mongholicus and Ephedra sinica, respectively, the raw material of which should be used. Wheat is the dried mature fruit of T. aestivum, which can be used without processing, while the stir-fried fruit, being thin and deflated, demonstrates better effect. The composition of Mulisan is Ostreae Concha 8.26 g, Astragali Radix 8.26 g, Ephedrae Radix et Rhizoma 8.26 g, and wheat 7.92 g. The medicinal materials should be ground into coarse powder and decocted with 450 mL water to reach a volume of 240 mL, and the decoction should be taken warm. In modern clinical practice, Mulisan has a wide range of indications, including spontaneous sweating and night sweating caused by Yang deficiency or Qi deficiency. The clinical disease spectrum treated by Mulisan involves endocrine system diseases, neurological diseases, respiratory system diseases, and cancer. This formula plays a significant role in the treatment of internal medicine diseases in traditional Chinese medicine. This study aims to provide a scientific basis for the subsequent research, development, and clinical application of Mulisan.

Objective:To explore the learning patterns of resident physicians in anesthesiology when performing tracheal intubation guided by Shikani laryngoscope, and provide a reference for the skill training of clinical anesthesiologists.Methods:From August 2023 to December 2024, a total of 19 resident physicians specializing in anesthesiology participated in this study at Peking University Third Hospital. All resident physicians received standardized training on clinical skills. None of them had received specialized training in Shikani laryngoscope-guided tracheal intubation. The relevant theoretical teaching and practical guidance were provided by the same senior attending physician throughout the study. A flipped-classroom teaching model was adopted, and each student was instructed by the teaching physician to perform the procedure on 15 cases in chronological order, resulting in a total of 285 cases. The cumulative sum (CUSUM) value for each tracheal intubation was calculated, and the learning curve was plotted using R software. A fourth-order polynomial nonlinear regression model was used to fit the curve and estimate the 95% confidence interval of the learning curve. The first-order derivative function of the regression model was further analyzed to reveal the dynamic changes in proficiency with the number of training sessions. The CUSUM curve was segmented using the maximum statistics test to identify the optimal breakpoint.Results:The maximum selection test revealed that the breakpoint for the increase in CUSUM level was at the eighth attempt.Conclusions:Resident physicians in anesthesiology can master Shikani laryngoscope-guided tracheal intubation after eight standardized training sessions. Moreover, the participants showed high satisfaction with the flipped-classroom teaching model.
