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 elucidate the complete genomic characteristics of the Akabane virus (AKV) DHL10M117 strain and the Tibet orbivirus (TIBOV) DH10M1019 strain, isolated from mosquito specimens collected in 2010 from Dehong prefecture, Yunnan province.Methods:The complete RNA virus sequences were obtained using metatranscriptomics and high-throughput sequencing.Results:The complete genome sequences of the DHL10M117 strain, consisting of the S, M, and L gene segments with lengths of 856 bp, 4 309 bp, and 6 869 bp, respectively, were acquired. Phylogenetic analysis indicated that the DHL10M117 strain is an AKV strain, closely related to the AKV strain DHL10M110, isolated from Yunnan. The S and M segment phylogenetic trees revealed that the strain is closely related to AKV strains circulating in southern China and Japan, and distantly related to strains from Australia, suggesting that this strain belongs to the Asian lineage with distinct regional characteristics. Homology analysis confirmed that the gene sequences of the S, M, and L segments of the DHL10M117 strain showed 100% nucleotide and amino acid identity with the DHL10M110 strain. Additionally, the complete genome sequences of the DH10M1019 strain, comprising ten gene segments (Seg-1 to Seg-10) with lengths of 3 950 bp, 2 904 bp, 2 769 bp, 1 978 bp, 1 772 bp, 1 638 bp, 1 165 bp, 1 142 bp, 1 103 bp, and 832 bp respectively, were obtained. Phylogenetic analysis showed that DH10M1019 is a TIBOV strain, with eight gene segments (Seg-1 to Seg-4, Seg-6, Seg-8 to Seg-10) clustering with known strains in the same major branch, while Seg-5 and Seg-7 formed distinct branches, independent of known reference strains, suggesting that DH10M1019 may represent a new serotype of TIBOV.Conclusions:Through complete genome sequence analysis, it was confirmed that DHL10M117 and DH10M1019 are AKV and TIBOV, which provided a scientific basis for the epidemiological characterisation, pathogenicity analysis and investigation of the two viruses.

Objective:The complete genome sequence characteristics of Quang Binh virus (QBV) and Manglie virus (MaV) isolated from mosquitoes in Daluo Town, Menghai county.Methods:Mosquitoes collected in Daluo Town, Menghai county in July 2012 were used for virus isolation. The nucleic acid was extracted from the supernatant of Aedes albopictus cell line (C6/36) showing cytopathic effect (CPE) positivity, and was sent to a company for sequencing after library construction. Phylogenetic and nucleotide/amino acid sequence similarity analysis was performed using DNAStar, Maff, and other softwares.Results:RNA libraries of strains BNDL1205 and BNDL1227 yielded 67 336 692 and 61 259 266 qualified gene sequences (reads) respectively. After assembly and alignment, sequences of lengths 10 865 bp and 10 864 bp were obtained. Sequence analysis indicated that they belong to QBV, with strains BNDL1205 and BNDL1227 clustering with QBV (strain VN180) isolated from Vietnam on the same evolutionary branch, sharing nucleotide similarity of 84.2% and 84.1%, and amino acid similarity of 94.6% and 94.4% respectively. RNA library of strain BNDL1223 yielded 48 622 610 qualified reads. After assembly and alignment, three gene fragments (Contigs) matched MaV. Further merging using SeqMan produced a complete nucleotide sequence of 9 219 bp. Analysis revealed that strain BNDL1223 is closely related to MaV isolated in Yunnan in 2018, sharing nucleotide similarity of 97.8% and amino acid similarity of 99.2%.Conclusions:During the investigation of arboviruses in mosquitoes in Daluo Town, Menghai county, three strains of viruses were identified: 2 strains of QBV and 1 strain of MaV. Local mosquitoes play a significant role in the transmission of QBV and MaV, necessitating enhanced monitoring and detection of local vector mosquitoes.

Systemic lupus erythematosus （SLE） is an autoimmune disease in which the immune system mistakenly attacks multiple tissues and organs of the body. The comorbid anxiety and depression are highly prevalent conditions among SLE， thereby worsening the prognosis of patients and posing a serious diagnostic challenge to the clinicians. The purpose of this article is to review the literature available for the influencing factors of comorbid anxiety and depression in SLE， and to provide references for optimizing treatment strategies for SLE patients with comorbid anxiety and depression. A total of 25 original research articles are included to provide a systematic and quantitative review， in which the genetic， immune， central nervous system and socio-psychological factors affecting the comorbid anxiety and depression in SLE are explored.

Illness anxiety disorder (IAD) is a psychiatric disorder defined by excessive worry about having or developing a serious undiagnosed medical condition. IAD can affect the social functions of patients and increase burdens imposed on the family and society. The concept of IAD was first proposed in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) in 2013. However, the rates of screening and identification of IAD are at a relatively low level in clinical practice, and the effectiveness of pharmacological and psychological intervention on IAD are still in the process of exploration and validation. The recognition of IAD should be enhanced and the efficacy of intervention need to be further improved. This article reviews the progress of clinical studies on IAD to improve clinicians′ understanding of the disease, and help them adopt appropriate treatments as early as possible to alleviate patient suffering and improve disease prognosis.

Objective:To explore the expression pattern of aryl hydrocarbon receptor (AhR) in mice peritoneal macrophages (PMs) after major trauma and analyze the effects of enhanced AhR expression on the inflammatory cytokine level and bactericidal ability after trauma.Methods:The experimental study method was used. Forty 6-8-week-old male C57BL/6J mice (the same mouse age, sex, and strain below) were divided into control group, post trauma hour (PTH) 2 group, PTH 6 group, and PTH 12 group according to the random number table (the same grouping method below), with 10 mice in each group. Mice in the latter 3 groups were constructed as severe trauma model with fracture+blood loss, while mice in control group were left untreated. The primary PMs (the same cells below) were extracted from the mice in control group, PTH 2 group, PTH 6 group, and PTH 12 group when uninjured or at PTH 2, 6, and 12, respectively. Then the protein and mRNA expressions of AhR were detected by Western blotting and real-time fluorescence quantitative reverse transcription polymerase chain reaction, respectively, and the gene expressions of AhR signaling pathway related molecules were analyzed by transcriptome sequencing. Twenty mice were divided into control group and PTH 6 group, with 10 mice in each group, and the PMs were extracted. The level of ubiquitin of AhR was detected by immunoprecipitation. Twelve mice were divided into dimethyl sulfoxide (DMSO) alone group, PTH 6+DMSO group, MG-132 alone group, and PTH 6+MG-132 group, with 3 mice in each group. After the corresponding treatment, PMs were extracted, and the protein expression of AhR was detected by Western blotting. Twenty mice were constructed as PTH 6 model. Then, the PMs were extracted and divided into empty negative control adenovirus (Ad-NC) group and AhR overexpression adenovirus (Ad-AhR) group. The protein expression of AhR was detected by Western blotting at 36 h after some PMs were transfected with the corresponding adenovirus. The rest cells in Ad-NC group were divided into Ad-NC alone group and Ad-NC+endotoxin/lipopolysaccharide (LPS) group, and the rest cells in Ad-AhR group were divided into Ad-AhR alone group and Ad-AhR+LPS group. The expressions of interleukin-6 (IL-6) and tumor necrosis factor α (TNF-α) in the cell supernatant were detected by enzyme-linked immunosorbent assay at 12 h after the corresponding treatment ( n=6). Twenty mice were obtained to extract PMs. The cells were divided into control+Ad-NC group, PTH 6+Ad-NC group, control+Ad-AhR group, and PTH 6+Ad-AhR group, and the intracellular bacterial load was detected by plate spread method after the corresponding treatment ( n=6). Data were statistically analyzed with one-way analysis of variance, least significant difference test, analysis of variance for factorial design, and independent sample t test. Results:Compared with 1.16±0.28 of control group, the protein expressions of AhR in PMs in PTH 2 group (0.59±0.14), PTH 6 group (0.72±0.16), and PTH 12 group (0.71±0.17) were all significantly decreased ( P<0.05). The overall comparison of the difference of AhR mRNA expression in PMs among control group, PTH 2 group, PTH 6 group, and PTH 12 group showed no statistical significance ( P>0.05). The AhR signaling pathway related molecules included AhR, AhR inhibitor, cytochrome P450 family member 1b1, cytochrome P450 family member 11a1, heat shock protein 90, aryl hydrocarbon receptor-interaction protein, and heat shock protein 70 interaction protein. The heat shock protein 90 expression of PMs in PTH 2 group was higher than that in control group, while the expressions of other molecules did not change significantly after trauma. Compared with that in control group, the level of ubiquitin of AhR in PMs in PTH 6 group was increased. Compared with that in DMSO alone group, the protein expression of AhR in PMs in PTH 6+DMSO group was decreased, while that in PMs in MG-132 alone group had no significant change. Compared with that in PTH 6+DMSO group, the protein expression of AhR in PMs in PTH 6+MG-132 group was up-regulated. At transfection hour 36, compared with that in Ad-NC group, the protein expression of AhR in PMs in Ad-AhR group was increased. At treatment hour 12, compared with those in Ad-NC+LPS group, the expressions of IL-6 and TNF-α in PM supernatant of Ad-AhR+LPS group were significantly decreased (with t values of 4.80 and 3.82, respectively, P<0.05). The number of intracellular bacteria of 1×10 6 PMs in control+Ad-NC group, PTH 6+Ad-NC group, control+Ad-AhR group, and PTH 6+Ad-AhR group was (3.0±1.8), (41.8±10.2), (1.8±1.2), and (24.2±6.3) colony forming unit, respectively. Compared with that in PTH 6+Ad-NC group, the number of intracellular bacteria of PMs in PTH 6+Ad-AhR group was significantly decreased ( t=3.61, P<0.05). Conclusions:Ubiquitin degradation of AhR in PMs of mice after major trauma results in decreased protein expression of AhR. Increasing the expression of AhR in post-traumatic macrophages can reduce the expressions of LPS-induced inflammatory cytokines IL-6 and TNF-α, and improve the bactericidal ability of macrophages after trauma.
