Autoimmune hepatitis (AIH) is a chronic, immune-mediated liver injury of unknown etiology. The onset of this disease involves the activation and recruitment of diverse immune and non-immune cells, which in turn trigger hepatic damage. Immune checkpoint molecules (ICM) are expressed on the surface of multiple cell types. By regulating cellular functional states, they help limit the intensity and duration of immune responses, thereby preventing excessive inflammation and tissue damage, and maintaining immune homeostasis. In AIH, however, this natural "braking" mechanism is impaired, leading to aberrant activation of both immune and non-immune cells and the breakdown of immune homeostasis. Consequently, ICM are likely to play a critical role in the pathogenesis of AIH. A deeper understanding of the function of ICM in AIH not onlyadvances our insight into the disease mechanism, but also suggests that targeting these molecules may represent a promising therapeutic strategy for the treatment of AIH.

ObjectiveThis study aims to explore the mechanism by which Yishen Huoxue Tongqiao Formula improves metabolism-neuroplasticity and treats unilateral vestibular labyrinth destruction by regulating the metabolic balance of glutamate (Glu)/γ-aminobutyric acid (GABA). Methods48 Sprague-Dawley (SD) adult rats were randomly divided into the sham operation group, model group, Yishen Huoxue Tongqiao Formula groups with low, medium, and high doses (9.20, 18.39, 36.78 g·kg-1), and betahistine group (1.62 mg·kg-1). A unilateral vestibular labyrinth destruction (vestibular dysfunction) model was established by intratympanic injection of chloroform into the right ear, while the control group received intratympanic injection of normal saline. Drugs were administered once daily for seven consecutive days. During the period, behavioral tests were performed to evaluate the behaviors of rats after unilateral vestibular labyrinth destruction. Hematoxylin-eosin (HE) staining and Nissl staining were used to observe the neuronal morphology in the medial vestibular nucleus. Golgi staining was employed to assess the number of dendritic spines of neurons in the medial vestibular nucleus. Ultra-performance liquid chromatography-tandem mass spectrometry (LC-ESI-MS/MS) was utilized to detect Glu/GABA. Immunofluorescence and immunohistochemistry were used to detect the expressions of neuronal nuclei (NeuN), growth-associated protein 43 (GAP-43), and glial fibrillary acidic protein (GFAP). Western blot and real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) were applied to determine the expressions of glutamate-immunoreactive (Glu-IR), GABA, GFAP, postsynaptic density protein 95 (PSD-95), and GAP-43. ResultsCompared with the sham operation group, the model group presented with head deviation, balance disorder, increased tail suspension score, nuclear consolidation of medial vestibular nerve neurons, and decreased Nissl bodies (P<0.01). The number of dendritic spines in neurons and NeuN-positive cells decreased. The content of Glu decreased. The content of GABA increased (Glu/GABA decreased). The expression of GAP-43 was down-regulated, and GFAP was up-regulated (P<0.05, P<0.01). The expressions of Glu-IR, PSD-95, and GAP-43 proteins, as well as Glu-IR mRNA decreased, while the expressions of GABA and GFAP proteins and mRNA increased (P<0.05, P<0.01). Compared with those in the model group, the head deviation, imbalanced behavior, and tail suspension scores in each treatment group decreased, with alleviated neuronal injury and recovered Nissl bodies (P<0.01). The number of dendritic spines of neurons increased, and the number of NeuN-positive cells rebounded. The content of Glu increased, and the content of GABA decreased (Glu/GABA increased). GFAP was down-regulated, and GAP-43 was up-regulated (P<0.05, P<0.01). The expressions of Glu-IR, PMD-95, and GAP-43 proteins, as well as Glu-IR mRNA increased, while the expressions of GABA and GFAP proteins and mRNA decreased. The effect was more significant in the high-dose group (P<0.01). ConclusionThe Yishen Huoxue Tongqiao Formula can alleviate vestibular dysfunction, and its mechanism may be associated with regulating the metabolic balance of Glu/GABA, mitigating neural damage, improving synaptic plasticity (promoting GAP-43 expression and inhibiting GFAP expression), and facilitating vestibular compensation.

Objective:To analyze the current status of routine supervision by the discipline inspection departments of public hospitals and the existing problems, and discussion of countermeasures, in order to provide reference for improving the supervision and management of discipline inspection.Methods:In January 2023, 19 full-time discipline inspection cadres from Beijing municipal public hospitals were selected as the subjects of the investigation. A self-made questionnaire was used, and the survey was conducted through the Questionnaire Star platform to understand the current status of routine supervision by discipline inspection departments in various public hospitals, with descriptive analysis of the questionnaire data. From October to December 2023, 12 full-time discipline inspection cadres from 8 Beijing municipal public hospitals were selected as interview subjects. Face-to-face interviews were conducted on how to effectively carry out routine supervision and how to utilize the roles of discipline committee members and branch discipline inspection committee members, with Colaizzi′s seven-step method used to analyze the interview data.Results:41 valid questionnaires were collected. The results showed that the routine supervision matters mainly involved political supervision and supervision of key links in the operation of power, including the implementation of the Central Eight Regulations and their detailed rules (40 people, 97.6%), the selection and appointment of cadres (40 people, 97.6%), the execution of party discipline by party members and leading cadres (39 people, 95.1%), and the implementation of significant decisions and deployments by the state, Beijing municipal and higher-level departments (38 people, 92.7%), etc.; routine supervision was mainly carried out through meeting supervision (41 people, 100.0%), collaborative supervision (41 people, 100.0%), special supervision (40 people, 97.6%), and letter and visit supervision (40 people, 97.6%); the weakness in routine supervision mainly included insufficient supervision of the party committee at the same level (29 people, 70.7%), etc. The lack of information technology means such as " internet" and " big data" (26 people, 63.4%), insufficient professional knowledge training for discipline inspection cadres and lack of professional personnel (26 people, 63.4%), insufficient supervision capabilities of discipline inspection cadres (26 people, 63.4%), limited methods of routine supervision (26 people, 63.4%), and insufficient innovation in supervision methods (26 people, 63.4%) had affected the effectiveness of routine supervision. Analysis of the interview materials yielded five themes: building a supervision system, grasping the key content of routine supervision, optimizing the methods of routine supervision, enriching the paths of supervision, and strengthening the construction of integrity culture and discipline inspection cadres.Conclusions:The routine supervision efficiency of the discipline inspection departments in Beijing municipal public hospitals still needs to be further improved. It is recommended to further improve the relevant work from the aspects of strengthening the construction of the discipline inspection supervision system, enhancing the efficiency of discipline inspection supervision, reinforcing information technology supervision methods, and perfecting the construction of discipline inspection cadre teams.

Objective To analyze and evaluate the implementation effect of tuberculosis prevention and control program in Wuhan, and to provide reference for scientific formulation of tuberculosis prevention and control measures. Methods Using the National Tuberculosis Information Management System, descriptive statistical analysis was carried out on the medical record information of pulmonary tuberculosis patients registered in Wuhan , 2016 - 2021. Results A total of 34 937 cases of pulmonary tuberculosis were registered in Wuhan , with an average annual incidence rate of 49.85/100 000. The incidence rate showed a downward trend year by year, with a statistically significant difference in 2016—2021 (χ2trend = 708.387, P<0.001). The patients mainly came from referrals, accounting for 71.86%, and the proportion of referrals varied significantly among different years (χ2=355.541, P<0.001). The diagnosis type was mainly pathogenic negative, accounting for 49.12%. The proportion of pathogenic negative had statistically significant difference among different years (χ2=1 354.830, P<0.001). The proportion of patients cured and completed the course of treatment reached 93.98%, with statistically significant differences in the proportions among different years (cured, χ2=1 080.252, P<0.001; completed the treatment course, χ2= 933.655, P<0.001). The sputum examination rate of newly diagnosed patients in each year reached over 90%, and the overall completion rate reached over 95%. The proportion of positive pathogens showed an increasing trend year by year. Conclusion The overall epidemic situation of tuberculosis in Wuhan is declining year by year, and tuberculosis prevention and control work has achieved remarkable results. Active screening in key areas and populations should be strengthened, and prevention and control strategies should be formulated by emphasizing the key and difficult points.
