ObjectiveTo investigate the effects of jatrorrhizine on endogenous metabolites and metabolic pathways in the mouse model of ulcerative colitis. MethodsThirty male C57BL/6J mice were randomly divided into the normal group， the model group， the low-dose and high-dose jatrorrhizine groups （0.04， 0.16 g·kg^-1）， and the mesalazine group （0.52 g·kg^-1）The mouse model of ulcerative colitis was established with 3% dextran sulfate sodium （DSS） and treated with different doses of jatrorrhizine by gavage. The changes in body weight， colon length， disease activity index （DAI）， and colonic histopathology were analyzed to evaluate the therapeutic effects of jatrorrhizine. UPLC-Q-TOF/MS was employed to determine the serum and fecal levels of metabolites in mice. Metabolomics methods were used to screen the differential metabolites， on the basis of which the potential therapeutic mechanism of jatrorrhizine on DSS-induced ulcerative colitis in mice was investigated. ResultsAfter intervention with jatrorrhizine， the model mice showed significantly decreased DAI（P<0.05，P<0.01）， recovered colon length，（P<0.05，P<0.01） and alleviated histopathology of the colon. The metabolomics study screened out 13 differential metabolites in the serum and 8 differential metabolites in the feces. The pathway enrichment analysis predicted three potential metabolic pathways： Biosynthesis of unsaturated fatty acids， phenylalanine， tyrosine and tryptophan biosynthesis， and phenylalanine metabolism. ConclusionJatrorrhizine may treat ulcerative colitis by regulating the biosynthesis and metabolism of amino acids and the synthesis of unsaturated fatty acids.

The preferred treatment for adrenal functional tumors is laparoscopic surgical resection. However, in recent years, various ablation techniques have gradually been applied in the treatment of adrenal tumors. This report presents the successful diagnosis and treatment experience of 4 aldosterone-producing adenomas and 1 cortisol-secreting adenoma treated with a combined cold and hot ablation system at Xi’an Daxing Hospital from Dec. 2023 to Dec. 2024, providing a new treatment approach for clinical exploration.

Mitochondria are organelles in eukaryotic cells that play a crucial role in cellular energy me-tabolism,oxidative stress,heat production,and signal transduction.Mitochondrial transplantation(MT)is currently one of the most advanced techniques for treating mitochondrial dysfunction and anti-aging re-search.This study aimed to explore the feasibility and effectiveness of xenogeneic MT by transplanting mitochondria from yak(Bos grunniens),domestic cattle(Bos taurus),and horse(Equus caballus)into mice(Mus musculus).The results demonstrated that mitochondria from yak,domestic cattle,and horse could be successfully transplanted into mice and maintained in various tissues and organs of the mice for at least 14 days,as confirmed by confocal imaging,digital PCR,and DNA sequencing.MT mice exhibi-ted positive biological effects,including increased ATP content and mitochondrial DNA copy number(P＜0.05),with the maximum effect observed on day 7,which was sustained until day 14.Reactive oxygen species(ROS)levels in MT mice significantly increased at 2 hours post-injection(P＜0.05),then grad-ually decreased towards baseline levels by day 7 and day 14(P＞0.05).These findings support the effec-tiveness of xenogeneic MT and suggest that the effects can be maintained for up to 14 days.This study provides scientific evidence for future clinical applications.

Objective To develop a novel method for measuring the Hounsfield Unit(HU)value of the surface carbon fiber material of the Varian Exact IGRT Couch,and to establish a treatment couch model in the treatment planning system(TPS)for correcting the attenuation of radiation dose caused by the treatment couch.Methods Two different field combinations were used to measure the radiation dose attenuation at the thin end and the middle medium-thickness part of the Varian Exact IGRT Couch.Dose deviations were measured when radiation passed through the treatment couch or not.Multiple sets of different HU values for the couch surface materials were defined in the TPS,and the dose difference between with and without couch was calculated under the same conditions as the measurements.The HU value of the treatment couch material corresponding to the actual measurements was found by data comparison and analysis.Results The attenuation for two interpenetrating fields was-2.49%to-1.69%at the thin end,and-3.43%to-2.23%at the medium-thickness part.The attenuation for multiple oblique incident fields ranged from-3.12%to-2.17%at the thin end,and that was-3.59%to-2.86%at the medium-thickness part.When the HU values of the couch model's surface and internal materials in the TPS were defined as-500 and-960,for two interpenetrating fields,the attenuation was-2.57%to-1.53%at the thin end,and-3.28%to-2.18%at the medium-thickness part;while for multiple oblique incident fields,the attenuation was-3.12%to-2.21%at the thin ends,and-3.42%to-2.43%at the medium-thickness part.These calculated results were consistent with the actual measurement values.For 40 verification plans,the average point dose difference between measurement and calculation in TPS were 0.90%and 0.89%at the thin end and medium-thickness part,respectively.Conclusion This novel measurement method can measure the HU value of the surface carbon fiber material and internal foam material of Exact IGRT Couch.Defining the HU values of these two materials of the couch model in the TPS as-500 and-960 can correct the radiation dose attenuation caused by the treatment couch,thereby improving the dose accuracy of the target volume and organs-at-risk.

Objective:To explore the characteristics of potential categories of chronic disease co-morbid patients' learned helplessness, and to analyze the differential characteristics of different categories of chronic disease co-morbid patients.Methods:Convenience sampling method was used to select patients with chronic disease co-morbidities who attended The NO.1 People's Hospital of Xiangyang, Hubei University of Medicine, from June to December 2023 as survey respondents. General information questionnaire, Learned Helplessness Scale, Health Questionnaire Somatic Symptom Cluster Scale, Kessler Psychological Distress Scale, and Comprehension Social Support Scale were used for the cross-sectional survey. The potential profile of learned helplessness, and the influencing factors of potential categories of learned helplessness was analyzed.Results:A total of 810 patients with chronic co-morbidities were investigated. There were 453 males and 357 females, aged (65.03±10.89) years old. The learned helplessness of these patients was categorized into three different potential categories, which were named as low-level learned helplessness group, medium-level learned helplessness group, high-level learned helplessness, accounting for 17.5% (142/810), 23.5% (190/810), and 59.0% (478/810), respectively. Compared with the low-level learned helplessness group, the probability of belonging to the medium-level learned helplessness group and high-level learned helplessness group was higher for patients with chronic co-morbidities with more severe physical symptoms ( OR=1.456, 1.391, both P<0.01). Compared with the low-level learned helplessness group, the probability of belonging to the medium-level learned helplessness group and high-level learned helplessness group was higher for patients with chronic co-morbidities with more severe the psychological distress ( OR=1.359, 1.917, both P<0.01). Compared with the low-level learned helplessness group, the probability of belonging to the medium-level learned helplessness group and high-level learned helplessness group was higher for patients with chronic co-morbidities with lower levels of social support ( OR=0.928, 0.874, both P<0.01). Compared with the low-level learned helplessness group, patients with a duration of illness >5 years were used as controls, patients with a duration of illness 2-5 years were more likely to belong to the medium-level learned helplessness group and high-level learned helplessness group ( OR=74.586, 62.620, both P<0.01). Compared with the low-level learned helplessness group, patients with neutral personalities were compared, patients with extroverted personalities had a lower probability of belonging to the medium-level learned helplessness group ( OR=0.105, P<0.05), while patients with introverted personalities had a lower probability of belonging to the medium-level learned helplessness group and high-level learned helplessness group ( OR=0.052, 0.046, both P<0.01). Conclusions:Patients with chronic disease co-morbidities have higher levels of learned helplessness during disease treatment and have more distinctive categorical characteristics. Healthcare professionals should adopt targeted nursing interventions according to different categories of chronic disease co-morbid patients to reduce the level of learned helplessness.
