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.

Objective:To investigate the effects of exosomes secreted by bone marrow mesenchymal stem cells (BMSCs) during osteogenic differentiation on the polarization of Raw264.7 macrophages and to elucidate the underlying mechanisms.Methods:PBS, uninduced BMSCs conditioned medium (CM), and osteogenic induction BMSCs CM for 7 d, 14 d, and 21 d were respectively added to Raw264.7 macrophages. After 48 h of treatment, Western blotting was used to detect and compare the expression of M1 markers of macrophages [inducible nitric oxide synthase (iNOS) and CD86] and M2 markers of macrophages [arginase-1 (ARG-1) and CD163] in each group. In addition, Raw264.7 macrophages were divided into three groups: the PBS group (only PBS added), the BMSCs-exo group (exosomes derived from uninduced BMSCs were added), and 7D-BMSCs-exo (exosomes derived from BMSCs were added after 7 days of osteogenic induction). The absorbance values of Raw264.7 cells in each group at 24 h, 48 h and 72 h were detected by an enzyme-linked immunosorbent assay (ELISA) reader. Western blotting was performed to assess changes of M1 or M2 marker proteins in Raw264.7 macrophages treated by exosome. The supernatants of the three groups of Raw264.7 macrophages were then co-cultured with BMSCs. Alizarin Red staining was used to quantify the formation of mineralized nodules, and alkaline phosphatase (ALP) staining was used to evaluate the osteogenic activity, and the expression levels of osteogenesis-related proteins Runx2, ALP, osteopontin (OPN), and osteocalcin (OCN) were detected. The migration ability of endothelial progenitor cells (EPCs) was detected by scratch assay for migration distance, and the angiogenesis ability was detected by in vitro tube formation assay for the number of vascular rings formed. The expressions of vascular endothelial growth factor (VEGF)-A and platelet-derived growth factor (PDGF) were detected by Western blot. The activation of the MAPK signaling pathway was evaluated by measuring phosphorylated and total P38 and ERK1/2 levels.Results:Western blot analysis showed that CM from BMSCs after 7 days of osteogenic induction (7D-BMSCs-CM) induced the strongest M2 polarization in macrophages. Compared with the PBS group, 7D-BMSCs-CM induced the most significant polarization of Raw264.7 macrophages to the M2 type, and increased ARG-1 and CD163 expression to 1.36±0.09 and 1.69±0.09, respectively ( P<0.05), while decreasing iNOS and CD86 to 0.21±0.03 and 0.29±0.03 ( P<0.05). The absorbance values of macrophages in the 7D-BMSCs-exo group were significantly higher than those in the PBS group at 24 h, 48 h, and 72 h ( P<0.05). Compared with BMSCs-exo group, 7D-BMSCs-exo upregulated the expressions of CD163 and ARG-1 while inhibited the expressions of iNOS and CD86 ( P<0.05). Alizarin red staining showed enhanced mineral deposition and a higher degree of mineralization in the 7D-BMSCs-exo group, the staining intensity of ALP also increased simultaneously, the Western-blot results showed that the protein expressions of Runx2, ALP, OPN and OCN were respectively higher than those in the PBS group ( P<0.05). The results of the scratch assay showed that the relative migration distance of EPCs cells in the 7D-BMSCS-exo group at 24 h reached 2.30±0.05 μm, which was higher than that in the PBS group 1.10±0.02 μm ( P<0.05). The Tube formation experiment showed that the number of vascular rings in the EPCs group was higher than that in the PBS group (30.3±2.5 and 15.0±1.0, P<0.05), and the protein expressions of VEGF-A and PDGF were upregulated. Furthermore, the levels of phosphorylated P38 and ERK1/2 were significantly reduced in the 7D-BMSCs-exo group 0.40±0.06 and 0.25±0.06 compared with the PBS group ( P<0.05). Conclusions:Exosomes secreted by BMSCs during osteogenic differentiation promote the M2 polarization of Raw264.7 macrophages, with the most pronounced effect observed at the 7th day. M2-polarized macrophages, in turn, enhance the osteogenic differentiation of BMSCs and the angiogenic capacity of EPCs. These processes are closely associated with the suppression of the MAPK signaling pathway.

Objective:To analyze the temporal distribution of other infectious diarrhea (OID) in Shenzhen and provide evidence for the prevention and control of OID.Methods:The incidence data of OID in Shenzhen from 2011 to 2023 were collected. The seasonal and trend decomposition using loess (STL), seasonal index method, concentration degree and circular distribution method were used to analyze the incidence trend and temporal distribution of OID.Results:A total of 477 611 cases of OID were reported in Shenzhen from 2011 to 2023, with an average annual incidence rate of 260.19/100 000 showing a fluctuating upward trend. The seasonal index method indicated that October-January was period with high incidence of OID in Shenzhen and the seasonal intensity began to decrease in 2020. STL revealed an obvious incidence peak in winter. The concentration method showed that OID had a certain seasonality before 2018 except 2016, but the seasonality was not obvious after 2018. The circular distribution results showed that r was 0.05, mean angle ā was 1.92° and angular standard deviation s was 141.93° ( Z=1 033.37, P<0.001), with the peak on January 1 st and the high incidence period from August 11 th to May 25 th. Conclusions:OID had a certain degree of seasonality in Shenzhen, with an obvious incidence peak in winter. Since the seasonal intensity of OID decreased after 2018, the surveillance, early warning and risk assessment of OID should be continued, and prevention and control measures should be adjusted timely according to the change in the characteristics of the epidemic.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Hypoxic-ischemic (HI) brain damage poses a high risk of death or lifelong disability, yet effective treatments remain elusive. Here, we demonstrated that miR-100-5p levels in the lesioned cortex increased after HI insult in neonatal mice. Knockdown of miR-100-5p expression in the brain attenuated brain injury and promoted functional recovery, through inhibiting the cleaved-caspase-3 level, microglia activation, and the release of proinflammation cytokines following HI injury. Engineered extracellular vesicles (EVs) containing neuron-targeting rabies virus glycoprotein (RVG) and miR-100-5p antagonists (RVG-EVs-Antagomir) selectively targeted brain lesions and reduced miR-100-5p levels after intranasal delivery. Both pre- and post-HI administration showed therapeutic benefits. Mechanistically, we identified protein phosphatase 3 catalytic subunit alpha (Ppp3ca) as a novel candidate target gene of miR-100-5p, inhibiting c-Fos expression and neuronal apoptosis following HI insult. In conclusion, our non-invasive method using engineered EVs to deliver miR-100-5p antagomirs to the brain significantly improves functional recovery after HI injury by targeting Ppp3ca to suppress neuronal apoptosis.

Objective To investigate the stent location and effectiveness in different types of iliac vein compression.Methods A retrospective analysis was conducted on patients with left iliac vein compression who underwent stent implantation at our department from June 2021 to December 2023. Based on the location of compression, patients were categorized into high, classical, and low types. The patients’ general information, lesion characteristics, stent details, stent patency, and clinical outcomes were analyzed and followed up.Results A total of 242 patients were included in this study. And 90. 9% (220 cases) were the classical type, 5.4% (13 cases) were the high type, and 3.7% (9 cases) were the low type. There was no significant difference in age distribution, gender ratio and comorbidities among the three groups. The length of inferior vena cava protruding from the high type was significantly longer than that of the classical type[(3.1±0.8) cm vs. (1.6±1.0) cm, P<0.001), but significantly shorter in the low type[(-0.7±2.4) cm vs. (1.6±1.0) cm, P<0.001). The mean follow-up time was (18.0±7.0) months. The stent patency rate was 97.0% at 1 year and 92.8% at 2 years postoperation. The clinical symptoms of the three groups were significantly relieved. No thrombosis was found in right limbs.Conclusions There is a significant difference in the location of the stent tip between classical and non-classical compression types. Complete coverage of lesion by the stent should be the prerequisite for stent placement in treatment of all three types. Small sample, short-term follow-up data suggested that stents can also relieve clinical symptoms and have good patency rate in the high compression type and the low compression type.

Objective To explore the effect and preliminary mechanism of the plant-derived immunostimulatory molecule,ophiopogonin,on enhancing the immune response of a subunit vaccine with the receptor-binding domain(RBD)of coronavirus spike protein as the antigen.Methods CCK-8 assay was used to determine the cytotoxicity of ophiopogonin D'(OPD')on bone marrow-derived dendritic cells(BMDCs).Female Balb/c mice were randomly divided into RBD,RBD/OPD',RBD/Alum,and control groups.The immunization dose was 5 μg of antigen per mouse and 100 μg of adjuvant per mouse,and immunization was carried out according to the intramuscular injection immunization procedure on days 0,21,and 42.The titers of specific IgG and its subtype antibodies were detected by ELISA.The cytokine levels in the supernatant of splenocytes were detected using ELISA.The number of splenocytes secreting IFN-γ was detected by ELISpot.Laser confocal microscopy was employed to observe the uptake of antigen by BMDCs.The phagocytic ability of BMDCs for antigen was quantitatively analyzed by flow cytometry.The mechanism of its enhanced immune effect was preliminarily explored using transcriptomics technology combined with bioinformatics research.Results When the concentration of OPD'was less than 5 μg/mL,the survival rate of BMDCs was 100%.After a single intramuscular injection in mice,except for a slight decrease in body weight,the other biochemical indicators were within corresponding normal ranges.After intramuscular injection immunization of the vaccine,the titers of serum-specific IgG,IgG1,and IgG2a in the RBD/OPD'group were significantly higher than those in the RBD group(P<0.05).Compared with the RBD group,the RBD/OPD'group induced a high-level Th1 cell immune response of IL-1β,TNF-α,and IFN-γ(P<0.01)and had more lymphocytes secreting IFN-γ(P<0.001).Laser confocal microscopy displayed that BMDCs took up more antigens after OPD'treatment,which was further confirmed with flow cytometry in quantitative analysis on antigen uptake rate(P<0.01).Transcriptomics results indicated that there was more significant enrichment of the PPAR signaling pathway in the RBD/OPD'group than the RBD group,suggesting that OPD'may activate the PPAR signaling pathway to exert its adjuvant effect.Conclusion OPD'effectively enhances the immune response of the RBD subunit vaccine,and its action mechanism may be related to the activation of the PPAR signaling pathway.
