ObjectiveTo explore the impact of comprehensive vocational rehabilitation on quality of life and return-to-work outcomes for individuals with mild work-related disability. MethodsA longitudinal observational study was conducted. A total of 343 work-injured employees receiving comprehensive vocational rehabilitation intervention in Guangdong Work Injury Rehabilitation Hospital from June, 2023 to December, 2024 were selected. The 36-item Short Form Health Survey (SF-36) was adopted to assess their health-related quality of life at admission and discharge. All subjects were followed up within one year after discharge to collect their return-to-work status. The differences in each dimension score of SF-36 among patients with different return-to-work outcomes (return to original post, transfer to new post and non-return to work) were compared, and the independent influencing factors of return-to-work outcomes were identified. ResultsComprehensive vocational rehabilitation intervention significantly improved the scores of physical functioning (PF), role-physical (RP) and role-emotional (RE) among work-injured employees (P < 0.05). At discharge, compared with patients who failed to return to work, patients returning to original post obtained significantly higher scores in PF, RP, bodily pain (BP), general health (GH), vitality (VT), social functioning (SF) and mental health (MH), patients transferred to new post achieved significantly higher scores in PF, BP, GH and SF (P < 0.05). Taking non-return-to-work status as the reference category, the multinomial logistic regression model showed the adverse factors for return to original post included low educational attainment (college diploma or below), on-site placement service, increased lost workdays and low employment intention (pre-contemplation and contemplation stages); the protective factor was positive evaluation of health transition (HT); for patients transferred to new posts, adverse factors were low employment intention (pre-contemplation stage) and increased lost workdays, while protective factors covered on-site placement service and positive HT evaluation. ConclusionComprehensive vocational rehabilitation can improve the quality of life for injured workers. Better quality of life is positively associated with return-to-work outcomes. HT, education level, job placement mode, lost workdays and employment willingness are independent factors impacting return-to-work outcomes.

Eight new diterpenoids, Isodons A-H (1-8), comprising seco-abietane and abietane-type structures, together with 13 known analogues (9-21), were isolated from Isodon lophanthoides (Buch.-Ham. ex D. Don) Hara. The compounds (+)-3/(-)-3, (+)-4/(-)-4, and (+)-5/(-)-5 were identified as three enantiomeric pairs. The planar structures and absolute configurations of 1-8 were determined through high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), 1D & 2D nuclear magnetic resonance (NMR) spectroscopy, electronic circular dichroism (ECD) calculations, and X-ray diffraction crystallography. A cholesterol 7α-hydroxylase (Cyp7a1) luciferase reporter assay revealed significant anti-cholestatic activities for compounds 1, (+)-4, 6, 7, 12-14, and 16. Additionally, compound 6 demonstrated anti-cholestatic effects through the farnesoid X receptor (FXR)-associated signaling pathways in vitro and in vivo. These findings suggest potential applications for I. Lophanthoides in pharmaceutical development.

This article interpreted the basic requirements for humanistic caring of patients in the operating room, the environment and facilities for humanistic caring, the procedures and measures for humanistic caring, and the quality management framework, aiming to assist administrators and clinical practitioners across various levels of medical institutions in accurately understanding and effectively implementing the standard, and to provide essential textual reference and practical guidance for promoting the application of the standard.

Bronchopulmonary dysplasia (BPD), characterized by impaired alveolarization and dysregulated vascularization, is a severe health burden for neonates worldwide. Hyperoxia induced acute lung injury is a major contributor to the progression and deterioration of BPD. An increasing number of animal studies have revealed that human umbilical cord blood derived mononuclear cells (hUCB-MNCs) infusion significantly attenuated the hyperoxia-induced acute lung injury through regeneration capacity. Currently, clinical application requires determination of the optimal dose and adjustment to good manufacturing practices. In this work, we comprehensively investigated the optimal dose of hUCB-MNCs in alleviating hyperoxia-induced lung injury in neonatal C57BL6/J mice. Mice with hyperoxia exposure were implanted with low (3×104cells/kg, Dl), middle (3×105 cells/kg, Dm) and high (3×106 cells/kg, Dh) dose of hUCB-MNCs at postnatal day 7. Three weeks after graft, characteristics exhibited in lungs including morphology, function and cytokine expression were thoroughly analyzed. Implantation of hUCB-MNCs sharply reverted the impaired lung architecture induced by hyperoxia exposure dose dependently as evidenced by indicated parameters. Attenuated expression of IL-1β concomitant with enhanced expression of IL-10 and IL-2 were shown in Dh inoculated groups, where Dl and Dm failed to restore the level of IL-10, IL-1β and IL-2. Significantly re-escalated marker of angiogenic marker VEGFA, CD31 in lung tissue were uniquely observed in Dh group. Mechanistically, our study revealed the appropriate dose of intravenous infusion of hUCB-MNCs in alleviating hyperoxia-induced lung injury through modulating reactive oxygen species response in neonatal mice.Therefore, a tight control of hUCB-MNCs density or levels of CB-MNC related products is of great significance.

Objective:To predict pre-treatment clinical parameters that are associated with poor response and prognosis to ursodeoxycholic acid (UDCA) in patients with primary biliary cholangitis (PBC) and to use second-line treatment drugs in the early stages to delay the progression of the disease so that patients can benefit from early-stage treatment.Methods:Patients diagnosed with PBC at the Second Affiliated Hospital of Kunming Medical University from 2013 to 2022 were collected. Two hundred fifty-seven cases were screened in accordance with the inclusion and exclusion criteria. The response and prognosis conditions one year after treatment were followed up in outpatient and inpatient departments, as well as through telephone calls. Statistical analyses were performed using t-tests, Mann-Whitney U test, χ2 test, Fisher's exact test, and logistic regression analysis according to different data. Results:A total of 257 PBC cases were included, with 223 females (86.80%) and 34 males (13.20%). Univariate and multivariate binary logistic regression analyses showed that baseline high albumin levels [odds ratio ( OR): 0.882, 95% confidence interval ( CI): 0.805～0.967, P=0.008] were a protective factor for PBC patients' response to UDCA treatment after adjusting for different confounding factors, while baseline high alkaline phosphatase ( OR: 1.012, 95% CI: 1.008～1.016, P<0.001) and baseline high neutrophil/lymphocyte ratio (NLR) level ( OR: 1.462, 95% CI:1.079～1.981, P=0.014) were risk factors for a poor response to UDCA. Trend analysis showed that the baseline NLR quantile was positively correlated with the risk of poor response to UDCA ( OR: 5.512, 95% CI: 1.040～29.216, P=0.045) in patients with PBC. Cox proportional hazards regression analysis identified that age [hazard ratio ( HR): 1.050, 95% CI: 1.019～1.082] and NLR value ( HR:1.089, 95% CI:1.021～1.161) were independent influencing risk factors for all-cause mortality in PBC patients ( P<0.05). Conclusion:Baseline high albumin levels are protective factors against a poor biochemical response to UDCA, while baseline high alkaline phosphatase levels and high NLR are risk factors for a poor biochemical response to UDCA in patients with PBC. Additionally, baseline high NLR values are positively correlated with poor biochemical response to UDCA treatment.

Hepatocellular carcinoma(HCC),as the most common type of liver cancer,poses a significant threat to global public health due to its high incidence and mortality rates.This paper delves into the etiology,pathogenesis,and syndrome differentiation of liver cancer from the perspective of"dispersing qi and fortifying the body resistance",based on the clinical experience of renowned traditional Chinese medicine(TCM)practitioner,Prof.Changquan Ling.Prof.Ling believes that the development of liver cancer is closely related to the disruption of liver qi flow,the accumulation of blood stasis over time,and the generation of toxin from long-term stagnation,accompanied by pathological changes such as imbalance of yin and yang,deficiency of the body's vital qi and accumulation of pathogenic factors,and internal blazing of cancer toxins.In terms of treatment,he emphasizes the principles of dispersing qi and fortifying the body resistance,addressing both the root cause and symptoms.This is achieved by regulating the functions of viscera,improving the stagnation of qi flow,and supplemented by methods such as clearing heat and detoxifying,and softening and dispersing hard masses,aiming to break the vicious cycle of qi stagnation,deficiency of vital qi,and pathogenic factor generation,thereby promoting the recovery from the disease.Through detailed analysis of clinical cases,this paper demonstrates Prof.Ling's unique insights and significant efficacy in treating liver cancer through"dispersing qi"to"fortify the body resistance",ultimately achieving"tumor suppression".This provides new references and perspectives for the clinical diagnosis and treatment of liver cancer in TCM.
