BACKGROUND: While emotional distress, encompassing anxiety and depression, has been associated with negative clinical outcomes, its impact across various clinical departments and general hospitals has been less explored. Previous studies with limited sample sizes have examined the effectiveness of specific treatments (e.g., antidepressants) rather than a systemic management strategy for outcome improvement in non-psychiatric inpatients. To enhance the understanding of the importance of addressing mental health care needs among non-psychiatric patients in general hospitals, this study retrospectively investigated the impacts of emotional distress and the effects of early detection and management of depression and anxiety on hospital length of stay (LOS) and rate of long LOS (LLOS, i.e., LOS >30 days) in a large sample of non-psychiatric inpatients. METHODS: This retrospective cohort study included 487,871 inpatients from 20 non-psychiatric departments of a general hospital. They were divided, according to whether they underwent a novel strategy to manage emotional distress which deployed the Huaxi Emotional Distress Index (HEI) for brief screening with grading psychological services (BS-GPS), into BS-GPS ( n = 178,883) and non-BS-GPS ( n = 308,988) cohorts. The LOS and rate of LLOS between the BS-GPS and non-BS-GPS cohorts and between subcohorts with and without clinically significant anxiety and/or depression (CSAD, i.e., HEI score ≥11 on admission to the hospital) in the BS-GPS cohort were compared using univariable analyses, multilevel analyses, and/or propensity score-matched analyses, respectively. RESULTS: The detection rate of CSAD in the BS-GPS cohort varied from 2.64% (95% confidence interval [CI]: 2.49%-2.81%) to 20.50% (95% CI: 19.43%-21.62%) across the 20 departments, with a average rate of 5.36%. Significant differences were observed in both the LOS and LLOS rates between the subcohorts with CSAD (12.7 days, 535/9590) and without CSAD (9.5 days, 3800/169,293) and between the BS-GPS (9.6 days, 4335/178,883) and non-BS-GPS (10.8 days, 11,483/308,988) cohorts. These differences remained significant after controlling for confounders using propensity score-matched comparisons. A multilevel analysis indicated that BS-GPS was negatively associated with both LOS and LLOS after controlling for sociodemographics and the departments of patient discharge and remained negatively associated with LLOS after controlling additionally for the year of patient discharge. CONCLUSION Emotional distress significantly prolonged the LOS and increased the LLOS of non-psychiatric inpatients across most departments and general hospitals. These impacts were moderated by the implementation of BS-GPS. Thus, BS-GPS has the potential as an effective, resource-saving strategy for enhancing mental health care and optimizing medical resources in general hospitals.

Loss of protein homeostasis is a hallmark of cellular senescence, and ribosome pausing plays a crucial role in the collapse of proteostasis. However, our understanding of ribosome pausing in senescent cells remains limited. In this study, we utilized ribosome profiling and G-quadruplex RNA immunoprecipitation sequencing techniques to explore the impact of RNA G-quadruplex (rG4) on the translation efficiency in senescent cells. Our results revealed a reduction in the translation efficiency of rG4-rich genes in senescent cells and demonstrated that rG4 structures within coding sequence can impede translation both in vivo and in vitro. Moreover, we observed a significant increase in the abundance of rG4 structures in senescent cells, and the stabilization of the rG4 structures further exacerbated cellular senescence. Mechanistically, the RNA helicase DHX9 functions as a key regulator of rG4 abundance, and its reduced expression in senescent cells contributing to increased ribosome pausing. Additionally, we also observed an increased abundance of rG4, an imbalance in protein homeostasis, and reduced DHX9 expression in aged mice. In summary, our findings reveal a novel biological role for rG4 and DHX9 in the regulation of translation and proteostasis, which may have implications for delaying cellular senescence and the aging process.

Objective: To investigate the effects of “Three Methods and Three Acupoints” (TMTP) Tuina therapy on spinal microcirculation in sciatic nerve injury (SNI). Methods: Thirty-six Sprague–Dawley rats were randomly assigned to four groups: normal, sham operation, model, and TMTP Tuina. Successful model induction was confirmed by observable hind limb lameness. After 20 sessions, hind limb grip strength and motor nerve conduction velocity (MNCV) were measured at baseline and following the 10th and 20th intervention. CD31 and α-SMA in the ventral horn of SNI model rats were detected using immunofluorescence. Motor neurons in the ventral horn were detected by Nissl staining. PTEN levels in the ventral horn were measured by ELISA, and PI3K, Akt, BDNF, VEGF, and HIF-1α expression was determined by RT-PCR. Spinal cord microcirculation was evaluated by western blotting analysis of the levels of Akt, p-Akt, BDNF, and VEGF. Results: Hind limb grip strength and MNCV significantly improved in the TMTP Tuina group compared to the model group (both P < .001). Morphology of ventral horn motor neurons in the TMTP Tuina group improved compared to the model group, with increased expressions of α-SMA (P = .002) and CD31 (P = .006). Western blot analysis indicated increased expression of VEGF (P = .005), p-Akt (P < .001), and BDNF (P = .008) in the ventral horn following Tuina treatment. RT-PCR analysis revealed increased expression of PI3K, Akt, BDNF, VEGF and HIF-1α (all P < .05). In contrast, expression of PTEN decreased compared to the model group (P < .001). Conclusion TMTP Tuina therapy may restore motor function in rats, enhance ventral horn motor neuron morphology, and promote angiogenesis and vascular smooth muscle proliferation. The mechanism may involve the activation of the PI3K/Akt signaling pathway.

Objective:To analyze the differences in clinical and endoscopic ultrasonography (EUS) findings between diffuse and focal IgG4-related autoimmune pancreatitis (IgG4-AIP).Methods:Data of patients diagnosed as having IgG4-AIP who underwent EUS at Chinese PLA General Hospital from September 2011 to April 2022 were retrospectively collected. General clinical data, EUS features, and postoperative pathology were analyzed for characteristic differences.Results:A total of 40 patients were included in the study, 60.03±10.87 years old, a higher proportion of males (85.0%, 34/40). All patients underwent EUS, and 28 underwent EUS-guided fine-needle aspiration. Among the 40 patients, 29 (72.5%) had diffuse type and 11 (27.5%) had focal type. Abdominal pain [65.5% (19/29) VS 18.2% (2/11), χ2=5.393, P=0.020] and thickening of the bile duct wall [51.7% (15/29) VS 9.1% (1/11), χ2=4.394, P=0.036] were more common in the diffuse type, while main pancreatic duct dilation [45.5% (5/11) VS 10.3% (3/29), χ2=4.146, P=0.042] was more common in the focal type, with the lesion most commonly located in the pancreatic head (90.9%, 10/11). There was no significant difference in the presence of chronic pancreatitis parenchymal changes between the two groups [34.5% (10/29) VS 27.3% (3/11), χ2=0.003, P=0.955]. Conclusion:There are certain differences in abdominal pain and biliary and pancreatic duct lesions between diffuse and focal AIP. The high expression of chronic pancreatitis characteristics is not observed in either group, which provides clues for the classification of AIP in clinical practice.

Background The active metabolite of benzo[a]pyrene (BaP), 7,8-dihydroxy-9,10-epoxybenzo[a]pyrene (BPDE), can form adducts with DNA, but the spectrum of BPDE-DNA adducts is unclear. Objective To identify the distribution of BPDE adduct sites and associated genes at the whole-genome level by chromatin immunoprecipitation followed by sequencing (ChIP-Seq), and serve as a basis for further exploring the toxicological mechanisms of BaP. Methods Human bronchial epithelial-like cells (16HBE) were cultured to the fourth generation inthe logarithmic growth phase. Cells were harvested and added to chromatin immunoprecipitation lysis buffer. The lysate was divided into experimental and control groups. The experimental group received a final concentration of 20 μmol·L⁻¹ BPDE solution, while the control group received an equivalent volume of dimethyl sulfoxide solution. The cells were then incubated at 37 °C for 24 h. Chromatin fragments of 100-500 bp were obtained through sonication. BPDE-specific antibody (anti-BPDE 8E11) was used to enrich DNA fragments with BPDE adducts. High-throughput sequencing was conducted to detect BPDE adduct sites. The top 1000 peak sequences were subjected to motif analysis using MEME and DREME software. BPDE adduct target genes at the whole-genome level were annotated, and Gene Ontology (GO) functional analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of BPDE adduct target genes were conducted using bioinformatics techniques. Results The high-throughput sequencing detected a total of 842 BPDE binding sites, distributed across various chromosomes. BPDE covalently bound to both coding and non-coding regions of genes, with 73.9% binding sites located in intergenic regions, 19.6% in intronic regions, and smaller proportions in upstream 2 kilobase, exonic, downstream 2 kilobase, and 5' untranslated regions. Regarding the top 1000 peak sequences, four reliable motifs were identified, revealing that sites rich in adenine (A) and guanine (G) were prone to binding. Through the enrichment analysis of binding sites, a total of 199 BPDE-adduct target genes were identified, with the majority located on chromosomes 1, 5, 7, 12, 17, and X. The GO analysis indicated that these target genes were mainly enriched in nucleic acid and protein binding, participating in the regulation of catalytic activity, transport activity, translation elongation factor activity, and playing important roles in cell division, differentiation, motility, substance transport, and information transfer. The KEGG analysis revealed that these target genes were primarily enriched in pathways related to cardiovascular diseases, cancer, and immune-inflammatory responses. Conclusion Using ChIP-Seq, 199 BPDE adduct target genes at genome-wide level are identified, impacting biological functions such as cell division, differentiation, motility, substance transport, and information transfer. These genes are closely associated with cardiovascular diseases, tumors, and immune-inflammatory responses.
