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.

Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

Objective Developing a new type of full-face respiratory protective mask for nuclear facility sites to enhance the sound transmission function and improve the facial adaptability. Methods Combined with feedback from on-site practical needs, this study utilized finite element simulation and ergonomic design methods to investigate the voice transmission units of full-face masks and the facial features of workers at key nuclear facilities. Based on the research results, a new full-face respiratory protection mask structure was designed. Results The optimized structure of passive thin film voice transmission unit significantly enhanced voice transmission efficiency, reducing average voice transmission loss by approximately 70% compared to the control group using thin plate units of equivalent thickness. The existing facial feature test panels insufficiently cover and unevenly classify the facial features of workers at key nuclear facilities. In this study, a specialized test panel based on measurement data achieved a total coverage of 98.5% with high distribution uniformity within each class, providing effective guidance for redesigning full-face mask structural parameters. In comparison to foreign products currently utilized in nuclear facilities, the newly designed full-face mask structure exhibited excellent tightness and structural safety and reliability, and can be cleaned, decontaminated, and reused. Conclusion The results of this study provide significant guidance for improving and optimizing full-face respiratory protection mask used at nuclear facilities, as well as promoting domestic production of high-quality full-face respiratory protection masks.

Glioma is the most common primary central nervous system tumor,mainly derived from glial cells,with strong invasiveness,easy recurrence,and poor prognosis.Glioblastoma is a high-grade glioma with the highest degree of malignancy.The clinical treatment method is mainly surgical resection,supplemented by compre-hensive treatment such as radiotherapy,chemotherapy,and electric field therapy,but the treatment effect is not satisfactory.In recent years,with the rapid development of the field of tumor immunotherapy,CD73 is a novel immune checkpoint related to adenosine metabolism,which can promote tumor progression by inhibiting anti-tumor immune responses and promoting angiogenesis.This article systematically reviews the mechanism of action of CD73 and discusses its biological role and application in glioma,aiming to provide potential treatment options for glioma patients.

Objectives:Fenofibric acid is extracted from the widely used hypolipemic fenofibrate,nowadays being approved for marketing around numerous nations and regions,nonetheless not in China.Present trial evaluated the efficacy and safety in the Chinese hypertriglyceridemia population. Methods:This is a multi-center,randomized,double-blind,placebo-controlled phase Ⅲ clinical trial.Patients from 3 different cohorts,including severe hypertriglyceridemia(HTG),moderate HTG and mixed-dyslipidemia(MD),were randomized at 1:1 ratio to receive fenofibric acid 135 mg or placebo daily for 12 weeks.The primary endpoint was the percentage change of triglyceridemia(TG)from baseline at week 12.Secondary endpoints were the percentage changes of other blood lipid indexes.At the same time,the incidence of medical adverse events was observed. Results:Among the three cohorts of patients with severe HTG(n=52),moderate HTG(n=23)and MD(n=52),the TG levels in the fenofibric acid-treated group decreased by(49.12±29.19)%,(49.95±25.19)%and(49.79±19.28)%,respectively from baseline to 12 weeks,while the corresponding placebo groups decreased by(18.88±40.69)%,(8.11±29.86)%and increased by(10.42±73.04)%,respectively from baseline to 12 weeks.The differences between treatment and placebo groups were statistically significant(P<0.017 for severe HTG cohort,P<0.05 for moderate and MD cohort).The high-density lipoprotein cholesterol(HDL-C)in the fenofibric acid-treated group increased by(25.51±21.45)%,(24.55±24.73)%,and(23.60±27.38)%,and the placebo group increased by(1.91±20.42)%,(2.40±9.32)%and(7.13±19.12)%,respectively,the differences between the two groups were statistically significant(all P<0.05).In the fenofibric acid group,adverse events with incidence>5%included upper respiratory tract infection(10.9%),abdominal pain(6.3%),and increased serum creatinine levels(6.3%),rates of adverse events were similar between the two groups(P>0.05). Conclusions:Fenofibric acid can significantly reduce triglycerides and elevate HDL-C levels safely in Chinese patients with severe to moderate HTG without statin or MD patients on top of statin therapy.

Objective To investigate the therapeutic effectiveness of ozone combined with low-temperature plasma coagulation therapy on patients with cervical spondylotic radiculopathy and its influence on inflammatory responses.Methods Ozone in combination with low-temperature plasma radio-frequency coagulation was applied to 75 patients with cervical spondylotic radiculopathy in Pain Medicine Department of Capital Medical University Affiliated Beijing Anzhen Hospital from May 2022 to May 2023.Pain scores were assessed using Visual Analog Scale(VAS)and Neck Disability Index(NDI)before and two weeks after treatment.Enzyme-linked immunosor-bent assay(ELISA)was used to analyze the level of tumor necrosis factor-alpha(TNF-α),interleukin-6(IL-6)and interferon-gamma(IFN-γ)before and two weeks after treatment.Results After treatment with ozone plus low-temperature plasma radiofrequency,VAS and NDI scores showed a significant decrease[VAS:5.36(4,7)vs.1.32(1,2),P＜0.000 1;NDI:32.72(24,70)vs.7.62(3.55,8.9),P＜0.000 1].Two weeks after surgical intervention,there was an effective reduction in the level of IL-6,TNF-αand IFN-γ alleviating the inflammatory re-sponse[IL-6:4.33(2.51,5.04)vs.3.49(2.08,4.43),P＜0.05;TNF-α:1.95(1.41,2.21)vs.1.61(1.02,2.03),P＜0.05;IFN-γ:1.84(1.18,2.47)vs.1.55(0.76,2.09),P＜0.05].Conclusions This Ozone combined with low-temperature plasma radiofrequency ablation is an effective technology for treatment of cer-vical spondylotic radiculopathy.

Objective To investigate the influence of different cell structures on the static and dynamic mechanical performance of porous titanium alloy scaffolds,and to provide a theoretical mechanical basis for the application of scaffolds in the repair of mandibular bone defects.Methods Porous titanium alloy scaffolds with diamond,cubic,and cross-sectional cubic cell structures were manufactured using three-dimensional printing technology.Uniaxial compression tests and ratcheting fatigue with compression load tests were conducted to analyze the static and dynamic mechanical performances of scaffolds with different cell structures.Results The elastic moduli of the diamond cell,cross-sectional cubic cell,and cubic cell scaffolds were 1.17,0.566,and 0.322 GPa,respectively,and the yield strengths were 71.8,65.1,and 31.8 MPa,respectively.After reaching the stable stage,the ratcheting strains of the cross-sectional cubic,diamond,and cubic cell scaffolds were 3.3%,4.0%,and 4.5%,respectively.The ratcheting strain increased with increasing average stress,stress amplitude,and peak holding time,and decreased with increasing loading rate.Conclusions The evaluation results of the static mechanical performance showed that the diamond cell scaffold was the best,followed by the cross-sectional cubic cell scaffold and the cubic cell scaffold.The evaluation results of the dynamic mechanical performance showed that the cross-sectional cubic cell scaffold performed the best,followed by the diamond cell scaffold,whereas the cubic cell scaffold performed the worst.The fatigue performance of the scaffold is affected by the loading conditions.These results provide new insights for scaffold construction for the repair of mandibular bone defects and provide an experimental basis for further clinical applications of this scaffold technology.

Objective:To investigate the significance of B-Raf proto-oncogene, serine/threonine kinase (BRAF) V600E mutation in the prediction of response to apatinib treatment in advanced radioactive iodine-refractory differentiated thyroid cancer (RAIR-DTC). Methods:Twenty patients (10 males, 10 females, age: 51.5(46.3, 65.0) years) with advanced RAIR-DTC from Peking Union Medical College Hospital between March 2016 and March 2023 were retrospectively enrolled, and all patients were treated with apatinib and underwent genetic sequencing (including BRAF V600E and telomerase reverse transcriptase (TERT) promoter). The serological and imaging data, progression-free survival (PFS) and overall survival (OS) data were collected during apatinib treatment. The Kaplan-Meier survival analysis (log-rank test) was performed, and Mann-Whitney U test were used to analyze the differences of duration of response (DOR) between mutation group and wild-type group. Then univariate and multivariate Cox regression analyses were conducted. Results:The PFS (35.3 vs 9.2 months, χ2=7.53, P=0.006) and DOR (25.8(7.4, 35.2) vs 8.2(2.5, 13.4) months, U=23.00, P=0.046) of the BRAF V600E mutation group were longer than those of the wild-type group. Univariate Cox regression analysis showed that the BRAF V600E mutation group had better PFS benefit (hazard ratio ( HR)=0.22 (95% CI: 0.06-0.72), P=0.013), and the risk of disease progression or death in patients with lung metastasis and bone or brain metastasis was 3.06(95% CI: 1.10-8.54, P=0.033) times higher than that in patients with lung metastasis alone. Further, multivariate cox regression analysis showed that only BRAF V600E mutation was an independent predictor of PFS ( HR=0.23 (95% CI: 0.07-0.80), P=0.021), suggesting that RAIR-DTC patients with BRAF V600E mutation might have better efficacy of apatinib. There was no significant difference in PFS ( χ2=1.34, P=0.247) and OS ( χ2=0.19, P=0.664) between TERT promoter mutation group and wild-type group. Conclusion:RAIR-DTC patients with BRAF V600E mutation have longer PFS and DOR after apatinib treatment than those with BRAF V600E wild-type, suggesting that BRAF V600E may be a potential biomarker to guide tyrosine kinase inhibitor (TKI) therapy and help to refine TKI treatment indications.

The coronavirus disease 2019 (COVID-19) epidemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is still ongoing. With the continuation of the epidemic, the SARS-CoV-2 genome is constantly mutating and evolving, producing more and more SARS-CoV-2 variants, which has brought severe pressure to the prevention and control of COVID-19. In view of the spread of COVID-19, it is extremely important to confirm the infection with SARS-CoV-2 and identify SARS-CoV-2 variants through nucleic acid detection. Therefore, it is urgent to develop highly sensitive and highly specific detection method for different application scenes, such as on-site, high-throughput and automated detection, to realize the diagnosis of SARS-CoV-2 and its variants. At present, researchers have used clustered regularly interspaced short palindromic repeats (CRISPR)-based nucleic acid detection technology combined with lateral flow strips and other technologies to establish a variety of diagnostic method for SARS-CoV-2 and SARS-CoV-2 variants, which can be applied to different scenes and regions. In this article, we summarize the research progress of CRISPR-based SARS-CoV-2 diagnostic method.
