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.

This study aims to explore the impact of host plants on the quality of Taxilli Herba and provide a theoretical basis for the quality control of Taxilli Herba. The components of Taxilli Herba from three different host plants(Morus alba, Salix babylonica, and Cinnamomum cassia) and its 3 hosts(mulberry branch, willow branch, and cinnamon branch) were detected by widely targeted metabolomics based on ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS). Principal component analysis(PCA), orthogonal partial least squares discriminant analysis(OPLS-DA), and Venn diagram were employed for analysis. A total of 717 metabolites were detected in Taxilli Herba from the three host plants and the branches of these host plants by UPLC-MS/MS. The results of PCA and OPLS-DA of Taxilli Herba from the three different host plants showed an obvious separation trend due to the different effects of host plants. The Venn diagram showed that there were 32, 8, and 26 characteristic metabolites in samples of Taxilli Herba from M. alba host, S. babylonica host, and C. cassia host, respectively. It was found by comparing the characteristic metabolites of Taxilli Herba and its hosts that each host transmits its characteristic components to Taxilli Herba, so that the Taxilli Herba contains the characteristic components of the host. The Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway analysis showed that the differential metabolites of Taxilli Herba from the three hosts were mainly enriched in flavonoid biosynthesis, arginine and proline metabolism, and glycolysis/gluconeogenesis pathways. Furthermore, the differential metabolites enriching pathways of Taxilli Herba from the three hosts were different depending on the host. In a word, host plants have a significant impact on the metabolites of Taxilli Herba, and it may be an important factor for the quality of Taxilli Herba.

OBJECTIVE:
To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM).
METHODS:
This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis.
RESULTS:
Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings.
CONCLUSIONS
RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective:To investigate the changes of the epidemiology and clinical characteristics of human metapneumovirus (hMPV) among children with acute lower respiratory tract infection (ALRTI) before and after the discontinuation of non-pharmaceutical interventions (NPI) during coronavirus disease 2019 epidemic.Methods:This was a retrospective cohort study. Children hospitalized at The Second Affiliated Hospital and Yuying Children′s Hospital of Wenzhou Medical University between January 2021 and December 2023, who were diagnosed with ALRTI by nasopharyngeal secretion testing for respiratory pathogens nucleic acid were enrolled. Clinical and laboratory data were collected. Children admitted between January 1, 2021 and January 7, 2023 were classified as the pre-NPI withdrawal group (abbreviated as pre-withdrawal group), while those admitted from January 8, 2023 afterward were classified as the post-NPI withdrawal group (abbreviated as post-withdrawal group). Nasopharyngeal secretions from the enrolled children were tested for 13 respiratory pathogens using polymerase chain reaction-capillary electrophoresis fragment analysis, and bacterial cultures were also performed. Statistical analyses were performed using the Mann-Whitney U test or chi-square test. Results:A total of 30 855 ALRTI cases were enrolled, with 1 679 of hMPV-positive. In the pre-withdrawal group, there were 861 cases with an age of onset of 2.0(1.0, 3.0) years, and the highest proportion was in the 1 to <3 years age group, accounting for 35.3%(304/861). In the post-withdrawal group, there were 818 cases with an age of onset of 3.0(2.0, 4.0) years, and the highest proportion was in the 3 to <5 years age group, accounting for 39.2%(321/818).The age of onset in the post-withdrawal group was significantly older than that in the pre-withdrawal group ( Z=7.69, P<0.001) .The hMPV detection rate was higher in the pre-withdrawal group than that in post-withdrawal group (5.75%(861/14 984) vs 5.15%(818/15 871); χ2=5.25, P=0.022). In the pre-withdrawal group, the epidemic peaks occurred in winter and spring, with the highest rates in January 2022(25.2%(224/890)) and March 2022 (21.6%(186/860)). In the post-withdrawal group, the epidemic peak shifted to spring and summer, and the detection rate became increased since April 2023(10.8%(136/1 258)). The post-withdrawal group showed lower rates of wheezing, shortness of breath, cyanosis, respiratory support, severe pneumonia, intensive care unit admission, and shorter hospital stays compared to the pre-withdrawal group ( χ2=69.09, 31.63, 12.97, 57.96, 55.73, 5.48 and Z=7.11, respectively, all P< 0.05).In the pre-withdrawal group, 412 cases (47.9%(412/861)) had other pathogens detected, compared to 445 cases (54.4%(445/181)) in the post-withdrawal group, indicating a significantly higher rate of co-infections in the post-withdrawal group ( χ2=7.20, P<0.05). The most commonly detected pathogens in both groups were Mycoplasma pneumoniae (MP), rhinovirus, and Streptococcus pneumoniae. However, the post-withdrawal group showed significantly higher detection rates of MP and influenza virus, but lower bacterial detection rates compared to the pre-withdrawal group ( χ2=39.41, 9.70, 5.63, respectively, all P<0.05). The detection rate of Haemophilus influenzae was 2.1%(17/818) in the post-withdrawal group which lower than that (6.7%(58/861)) in the pre-withdrawal group, and the difference was statistically significant ( χ2=21.32, P<0.001). Conclusions:In 2023, following the withdrawal of NPI, the epidemic peak of hMPV in Wenzhou area is delayed to spring and summer. The age of children with hMPV-associated ALRTI increases, with the majority being 3 to <5 years old. The overall severity of the disease decreases. However, the detection of mixed pathogens increases, with MP being the most common, while bacterial detection decreases.

This study aims to identify the main chemical compounds, investigate the effects of different drying methods on the quality, and determine the appropriate drying method of Callicarpae Nudiflorae Folium. UPLC-UV-Q-TOF-MS was employed to characterize and identify 35 main compounds, including phenylethanoid glycosides, flavonoids, and iridoids in Callicarpae Nudiflorae Folium. A method for the simultaneous determination of 8 compounds with strong UV absorption and high content was established to evaluate the quality of Callicarpae Nudiflorae Folium dried by different methods. UPLC-UV-Q-TOF-MS combined with principal component analysis(PCA) was employed to compare the Callicarpae Nudiflorae Folium samples treated by microwave drying at different power(119, 231, and 385 W), drying in the shade, sun drying, and oven drying at different temperatures(50, 60, 70, 80, 90, and 100 ℃). The total content of decaffeoyl acteoside, picroside Ⅲ, galuteolin, forsythin B, acteoside, isoacteoside, 6-hydroxyluteolin-7-glucoside, and caffeic acid in Callicarpae Nudiflorae Folium, as well as the content of most compounds, decreased with the rise in drying temperature and with the decrease in microwave power. Considering the content of compounds, low carbon, and energy saving, microwave drying at 231 W, low-temperature drying, or natural drying is recommended for the production of Callicarpae Nudiflorae Folium. This study provides a scientific basis for the selection of drying methods for Callicarpae Nudiflorae Folium at the place of origin and for the improvement of quality standards.
