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.

Prostate cancer (PCa) is the most common urological malignancy in men worldwide, and its incidence is increasing annually. Radiotherapy is one of the main treatment methods for PCa. However, some patients still have recurrence, local progression, and even distant metastasis after receiving radical radiotherapy. As an emerging tumor treatment strategy, immunotherapy has made great progress in the treatment of various solid tumors. Owing to the inherent immune escape mechanism of PCa, the efficacy of immunotherapy is unsatisfactory. Therefore, new combined strategies must be explored to improve the efficacy of immunotherapy for PCa. With the in-depth study of the tumor immune microenvironment, the immunomodulatory effect of radiotherapy has gradually attracted attention. Researchers found that the immunomodulatory effect of radiotherapy depends on the dose. Low-dose radiotherapy can enhance tumor immunogenicity by remodeling the tumor microenvironment, whereas high-dose radiotherapy can further activate the innate immune signaling pathway by directly inducing the immunogenic necrosis of tumor cells. Therefore, the synergistic strategy of radiotherapy and immunotherapy has become a research hotspot. This work aims to review the regulatory effect of radiotherapy on PCa antitumor immunity, clarify the latest progress and potential clinical value of radiotherapy combined with immunotherapy, and provide a theoretical basis and new research directions for optimizing the combination immunotherapy strategies for prostate cancer.

Objective:To explore the genotype-phenotype relationship of Wilson's disease (WD) and further study the mutation spectrum in the ATP7B gene.Methods:The clinical data and genetic test results of 115 cases with WD diagnosed in the First Affiliated Hospital of Zhengzhou University from 2015 to 2022 were retrospectively analyzed. The rank sum test was used for quantitative data comparison, and χ2 test was used for count data comparison. Multivariate logistic regression was used to analyze the relationship between patients' genotype and phenotype. Results:The onset of liver manifestations (hepatic type) accounted for 60.9%, neurological symptoms (cerebral type) for 13.0%, and mixed hepato-cerebral symptoms for 26.1%. Presymptomatic individuals (hepatic types) accounted for 62.9%. Next-generation sequencing- diagnosed WD cases accounted for 87.8%. Combined multiplex ligation-dependent probe amplification assay-diagnosed WD cases accounted for 89.6%. A single case with a detected pathogenic locus accounted for 10.4%. The diagnostic rate of WD by genetic testing combined with clinical data was 100%. A total of 76 ATP7B mutations were detected, and the top three mutation frequencies were c.2333G>T (p.Arg778Leu) (30.7%), c.2975C>T (p.Pro992Leu) (7.3%), and c.2621C>T (p.Ala874Val) (6.4%). The mutations were mainly distributed in exons 8, 11-13, and 15-18, accounting for more than 90% of the total mutations. Eight new mutations were found, including c.3724G>A (p.Glu1242Lys), c.3703G>C (p.Gly1235Arg), c.3593T>C (p.Val1198Ala), c.2494A>C (p.Lys832Gln), c.1517T>A (p.Ile506Lys), c.484G>T (p.Glu162Ter), c.1870-49A>G, and the missing of exons 10-21. Liver histopathology showed cellular edema, degeneration, inflammation, and necrosis, as well as a 42.8% copper staining positive rate. Genotype-phenotype analysis showed that the p.Arg778Leu mutation had higher alanine aminotransferase (ALT) levels than those carrying other mutations ( P=0.024), while the homozygous mutation of p.Arg778Leu was associated with cerebral-type patients ( P=0.027). Conclusion:Genetic testing plays an important role in the diagnosis of WD. p.Arg778Leu is the first high-frequency mutation in the Chinese population, and patients carrying it have higher ALT levels. The p.Arg778Leu homozygous mutation is prone to causing cerebral-type WD. This study expands the ATP7B gene mutation spectrum.

Objective To explore the effect of Sufu on lung adenocarcinoma by observing its mutation and the changes in Gli1 transcription after its mutation.Methods cBioPortal for Cancer Genomics was used to obtain the mutation status of Sufu in lung cancer.Four Sufu single base mutation vectors were constructed and transfected into lung adenocarcinoma cell lines A549 and H1975 to establish cells with Sufu overexpression and knockout.Wounding healing assay was employed to determine the effect of Sufu on cell migration,and RT-qPCR,immunofluorescence assay and dual luciferase reporter gene assay were utilized to explore the changes in Gli1 transcription after Sufu mutation.Results cBioPortal data showed that the mutation rate of Sufu in lung cancer was 11.76％in squamous cell carcinoma(2/17),0.96％in adenocarcinoma(6/625),1.01％in small cell lung cancer(4/396),and 0.69％in non-small cell lung cancer(77/11 227).The median survival of lung cancer patients was significantly decreased in those with Sufu mutation than those without(38.00 vs 54.34 months,HR=1.943,P＜0.05).A549 cells were sensitive to Sufu knockout,and it resulted in significant increase of the transcription level of Gli1(P＜0.05).Overexpression of Sufu inhibited cell migration ability in both A549 and H1975 cells(P＜0.05).Sufu mutation had no significant influence on the location of Gli1 in the cells.The Sufu-T411M mutation up-regulated the the transcription level of Gli1(P＜0.05).Conclusion Sufu has an inhibitory effect on lung adenocarcinoma metastasis,and can be regarded as a potential target for lung adenocarcinoma metastasis.

OBJECTIVE To explore the clinical characteristic manifestation of Rosai-Dorfman disease(RDD)involving the nasal cavity and paranasal sinuses.METHODS The clinical data of 16 patients with RDD involving the nasal cavity and paranasal sinuses who received treatment in Department of Rhinology of Beijing Tongren Hospital Affiliated to Capital Medical University from December 2016 to December 2023,were retrospective analyzed.RESULTS The male to female ratio was 1:3,with an average age of 47.4 years and an average disease duration of 22.34 months.There were 14,3,5,6 and 1 patients who complained of nasal congestion,dry nose,decreased sense of smell,head and face pain,and bulging/diplopia,respectively.There were 9 patients who had external nasal swelling.There were 14 RDD patients who were involved at least the nasal septum,12 patients who were simply affected in the nasal cavity,and 3 cases who involved the paranasal sinuses.There was 1 case belonged to a mixed type of RDD.There were 8 of 10 cases who were misdiagnosed or missed due to intraoperative rapid freezing.Endoscopic examination showed bilateral bulging in 9 patients'nasal septum,and nodular or granular new growth on 7 patients'nasal floor and inferior turbinate surface.Sinus CT found 9 patients'the nasal septum area showed a circular uniform soft tissue shadow or symmetrical soft tissue thickening shadow,5 patients'nasal floor and inferior turbinate showed obvious soft tissue thickening shadow.CONCLUSION RDD involving the nasal cavity and paranasal sinuses has certain typical features in external nasal manifestations,endoscopic and imaging examinations.Comprehensive judgment can help improve the feasibility of clinical diagnosis of RDD.

OBJECTIVE To determine the prevalence of frontal recess cells variations in patients with frontal sinus associated headache according to the International Frontal Sinus Anatomy Classification(IFAC).METHODS A retrospective study was conducted on the CT scans of sinuses in patients with frontal sinus associated headache.We reviewed 46 patients with frontal sinus-related headache who had clinical symptoms and were relieved after nasal endoscopic surgery.The development of frontal recess cells in the frontal recess drainage area was analyzed,and the variation of middle meatus and sinus involvement were analyzed in the same time.The Anatomical variations and imaging characteristics of frontal recess cells development in patients with frontal sinus associated headache were analyzed.RESULTS A total of 92 sinus CT profiles were analyzed in 46 patients.The most common cells were agger nasi cell(ANC)(100%,92/92),followed by supra bulla cell(SBC)(78.3%,72/92),supra agger cell(SAC)(67.4%,62/92),supra bulla frontal cell(SBFC)(27.2%,25/92),supra agger frontal cell(SAFC)(20.7%,19/92),frontal septal cell(FSC)(8.7%,8/92)and supraorbital ethmoid cell(SOEC)(0%,0/92).In the conventional frontal sinus drainage area,SAFC(P=0.0108),SAC(P=0.0104)and SAFC(P=0.0088)in the IFAC classification were significantly associated with the occurrence of frontal sinus associated headache.At the same time,the middle concha bullosa also showed a significant correlation with the occurrence of frontal sinus associated headache in the lower segment of the frontal recess drainage channel(P=0.0390).CONCLUSION In the frontal recess drainage channel,the abnormal development of SAC,SAFC,SBFC and the middle concha bullosa are significantly correlated with frontal sinus associated headache.

OBJECTIVE To test whether there are some differences among chronic rhinitis,chronic rhinosinusitis patients with nasal polyps(CRSsNP)and without nasal polyps(CRSsNP)in symptom severity,health-related quality-of-life impairment,and objective inflammatory factors.METHODS A total of 154 consecutive patients who had been treated at the Otolaryngology Department of Beijing Tongren Hospital from January 2017 to December 2018 were recruited in this study.The patients aged 18-70 years,with 106 males and 48 females.All patients performed endoscopic examination,nasal exhaled nitric oxide(nNO),skin prick test(SPT),sinus CT scan,complete blood count,and fulfilled the visual analogue scale(VAS)self-assessment of nasal symptoms and the SNOT-22 questionnaire under the guidance of the physician.According to the inclusion criteria,A total of 43 patients with CR,58 patients with CRSsNP and 53 patients with CRSwNP were enrolled in our study.RESULTS The total SNOT-22 score in CRSsNP group was significantly lower than that in CR and CRSwNP groups(30.0±19.4 vs.41.1±21.9,30.0±19.4 vs.40.9±18.7,P<0.05),and there was no significant difference between CR group and CRSwNP group.The average scores of nasal symptoms and extranasal symptoms in CRSwNP group were the highest;the scores in CRSsNP group were lower.The impact of CR patients on sleep damage was significantly higher than that in CRSsNP patients(9.9±6.2 vs.5.1±5.3,P<0.05),and there was no significant difference between CR group and CRSwNP group(9.9±6.2 vs.7.1±5.7,P>0.05).When patients suffered with positive SPT,there was no statistical difference in symptom scores and SNOT-22 scores between CR,CRSsNP,and CRSwNP;but with negative SPT,there was a significant statistical difference in both symptom scores and SNOT-22 scores among the three groups.CONCLUSION CR,CRSsNP and CRSwNP have a significant impact on quality of life,respectively.In terms of symptom scores and quality of life scores,the CR group and CRSwNP group are similar and the scores are higher than that of the CRSsNP group.However,the objective inflammation factors are not consistent with the subjective symptom scores and quality of life scores.

OBJECTIVE To predict biomarkers of type 2 inflammation in chronic rhinosinusitis with nasal polyps(CRSwNP)by employing peripheral blood indicators.METHODS CRSwNP patients admitted to the Rhinology Department of Beijing Tongren Hospital from June 2020 to May 2022 were enrolled and their basic clinical data were collected.The blood percentage of eosinophils(Eos%),Eos count,periostin and total IgE,as well as mucosal interleukin-5(IL-5)and Staphylococcus aureus enterotoxin-immunoglobulin E(SE-IgE)were tested.The receiver operating characteristic(ROC)curve was used to evaluate the predictive value of each blood indicator for positive mucosal expression of IL-5/SE-IgE.The logistic regression was employed to screen multiple blood indicators with predictive value for positive mucosal expression of IL-5/SE-IgE in order to construct a nomogram model.RESULTS The proportion of asthma,blood Eos%,periostin and total IgE in CRSwNP patients showed statistical differences between IL-5/SE-IgE positive and negative subgroups.ROC univariate analysis demonstrated that blood Eos%,Eos count,periostin and total IgE could predict mucosal IL-5 positivity with AUC ranging from 0.655 to 0.784,and mucosal SE-IgE positivity with AUC ranging from 0.721-0.802.The logistic regression confirmed that blood Eos%and total IgE,as well as blood periostin and total IgE were independent predictors for mucosal IL-5 and SE-IgE positivity,respectively.The nomogram models were constructed for predicting IL-5/SE-IgE positivity in CRSwNP mucosa,with consistency incides(C-index)of 0.804 and 0.81,indicating good predictive accuracy.CONCLUSION The nomograms constructed based on blood Eos%and total IgE,as well as blood periostin and total IgE,could have good predictive value for the positive mucosal expression of IL-5 and SE-IgE in the CRSwNP,which help to predict the severity of endotype and phenotype of CRSwNP.
