Depression is closely associated with a neuro-endocrine-immune(NEI)system imbalance.The"excessive vitality leading to restraint and counter-regulation(Kang Hai Cheng Zhi)"theory elucidates the self-regulating mechanism for maintaining dynamic equilibrium in the body,and serves as an importance principle guiding treatment formulation and medication selection.Based on the correlation between NEI system imbalance and the traditional Chinese medicine pathogenesis of depression,and integrating the"Kang Hai Cheng Zhi"theory,the author posits that the pathogenesis of depression lies in overactive liver invading spleen,earth dampness impeding wood′s ascendancy,and disharmony between body and mind,as well as imbalance in storage and discharge functions of liver and kidney,disharmony between Yin and Yang,and disrupted counter-regulation.This dosely aligns with two key pathological methanisms at the micro level:microglial-limbic system homeostatic imbalance and hypothalamic-pituitary-adrenal axis-inflammatory circuit dysregulation.Clinically,the treatment principle for depression adheres to supporting the counter-regulation to restrain excess,with herbal interventions using strategies such as restraining wood to support earth,dredging earth to unblock wood,and harmonizing pivotal functions,as well as nourishing water to nurture wood,warming kidney to tonify liver,and relieving depression to calm the spirit.These approaches aim to regulate the liver,spleen,and kidney,embodying the core therapeutic tenet of"striving for equilibrium,"thereby restoring the body′s self-regulating capability.

Objective To explore the ability of different regions of interest(ROI)location settings for the detection of bronchial artery and pulmonary vascular lesions in children with hemoptysis via computed tomography angiography(CTA)examination.Methods The hemoptysis group(79 cases)who underwent chest CTA examination and the control group(79 cases)with negative CTA results were retrospectively selected.The ROI of the hemoptysis group were placed in the pulmonary trunk,left ventricle,ascending aorta and descending aorta,which were defined as groups 1,2,3 and 4 respectively.Clinical data(age,sex)and CT parameters,including bronchial artery diameter,ascending aorta CT value,pulmonary artery CT value,△CTA-PA,bronchial artery image score,pulmonary artery image score,were recorded and analyzed,respectively.Results There was a statistically significant difference in the diameter of the left and right bronchial arteries between the hemoptysis group and the control group(P＜0.05).In the hemoptysis group,there were statistically significant differences in the image scores of the left and right bronchial arteries,pulmonary artery image scores,and△CTA-PA among the four subgroups(P＜0.05).According to post-hoc comparison results,there was a statistically significant difference in the overall mean scores of the right bronchial artery image score(x2=11.333,P＜0.05)and left bronchial artery image score(x2=8.111,P＜0.05)between groups 2 and 3.Conclusion When ROI is placed in the ascending aorta,bronchial artery lesions and pulmonary vascular lesions can be detected simultaneously in CTA examination,which is helpful for the diagnosis of hemoptysis vascular etiology in children.

ObjectiveTo investigate the clinical features of patients with acute-on-chronic liver failure （ACLF）， and to construct a risk scoring table that can accurately predict the prognosis of patients in the early stage. MethodsA retrospective analysis was performed for the clinical data of 502 patients with ACLF who were admitted to Tangdu Hospital， Air Force Medical University， from January 1， 2010 to December 31， 2020 （training set）， and the influencing factors for 28-day mortality rate were identified. The 69 ACLF patients who were admitted to Tangdu Hospital， Air Force Medical University， from January 1 to December 31， 2021 were enrolled as the validation set. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. A univariate Cox regression analysis was used to obtain the early warning indicators associated with the 28-day prognosis of ACLF patients， and variance inflation factors were used to assess multicollinearity among predictors； a multivariate Cox regression analysis was used to construct a risk model for ACLF prognosis （mortality）. A risk scoring table for ACLF prognosis （mortality） was developed based on regression coefficients （β） from the model equation and weight assignments in the nomogram. Internal validation and comparison were performed for the risk model for ACLF prognosis （mortality）， the scoring table for ACLF prognosis （mortality）， and other scoring models （Child-Turcotte-Pugh ［CTP］ score， Model for End-Stage Liver Disease ［MELD］ score， MELD combined with serum sodium concentration ［MELD-Na］ score， and integrated MELD ［iMELD］ score） in the training set， while external validation and comprehensive evaluation of the scoring table and the other scoring models were performed in the validation set. The Nagelkerke’s R² test and the Hosmer-Lemeshow test were used to assess the degree of fitting of the risk model for ACLF prognosis （mortality）， the scoring table for ACLF prognosis （mortality）， and other scoring models， and fitting curves were plotted. C-index was used to assess the discriminatory ability of the scoring table for ACLF prognosis （mortality） and the other scoring models， and the Z-test was used for comparison of C-index between different models. The decision curve analysis was used to compare the clinical benefits of the scoring table for ACLF prognosis （mortality） and the other scoring models. ResultsThe multivariate Cox regression analysis showed that age （hazard ratio ［HR］=1.027， 95% confidence interval ［CI］： 1.015 — 1.039， P<0.001）， hepatic encephalopathy grade （grade 1： HR=2.928， 95%CI： 1.463 — 5.858， P=0.002； grade 2： HR=3.811， 95%CI： 2.078 — 6.988， P<0.001； grade 3： HR=3.916， 95%CI： 1.917 — 8.001， P<0.001； grade 4： HR=6.966， 95%CI： 4.559 — 10.644， P<0.001）， an increase in total bilirubin （TBil） by ≥17.1 μmol/L per day （HR=1.771， 95%CI： 1.248 — 2.513， P=0.001）， creatinine （HR=1.005， 95%CI： 1.004 — 1.006， P<0.001）， neutrophil count （HR=1.092， 95%CI： 1.060 — 1.126， P<0.001）， and international normalized ratio （HR=1.298， 95%CI： 1.187 — 1.418， P<0.001） were independent risk factors associated with the 28-day mortality rate of ACLF patients， and a risk scoring table was constructed for ACLF prognosis （mortality）. The Nagelkerke’s R² test showed that the risk scoring table for ACLF prognosis （mortality） had an R² value of 0.599 in the training set and 0.722 in the validation set， which were higher than the R² values of CTP， MELD， MELD-Na， and iMELD scores. The Hosmer-Lemeshow test showed that the risk scoring table for ACLF prognosis （mortality） had a P value of 0.280 in the training set and 0.788 in the validation set. The C-index analysis showed that the scoring table had a higher C-index than the other scoring models in the validation set （all P<0.001）， as well as a higher C-index than CTP score in the training set （P<0.001）. The decision curve analysis showed that the risk scoring table for ACLF prognosis （mortality） had higher clinical net benefits than the other scoring models. ConclusionCompared with other scoring models currently used in clinical practice， the novel risk scoring table for ACLF prognosis （mortality） constructed based on the six predictive factors of age， hepatic encephalopathy grade， an increase in TBil by ≥17.1 μmol/L per day， creatinine， neutrophil count， and international normalized ratio has a relatively high value in predicting the 28-day prognosis of ACLF patients.

Objective:To analyze the epidemiological characteristics of herpes zoster (HZ) in Zhoushan and Shaoxing cities of Zhejiang Province from 2022 to 2024.Methods:The HZ data were obtained from the Zhejiang Regional Health Information Platform. Specifically, information was sourced from 42 public hospitals and 149 primary healthcare institutions in Zhoushan and Shaoxing, covering both outpatient and inpatient records (e.g., name, sex, date of birth, ID number, visit date, diagnosis code, admission/discharge dates, and medical expenses). Additionally, vaccination records were matched by ID number from the Zhejiang Immunization Planning Smart Service Information System, including vaccination date, dose, and manufacturer. Permanent resident population data for both cities were collected and stratified by age, sex, and district/county. Based on these data, the epidemiological characteristics of HZ, such as incidence rate, hospitalization rate, and recurrence rate, as well as the occurrence of complications and vaccination, were analyzed.Results:From 2022 to 2024, a total of 45 280 initial HZ cases were identified. The mean age of patients was 57.82 years, with 52.69% being female patients and 95.01% being outpatient cases. Notably, the overall incidence rate of HZ was 3.18‰, showing a significant upward trend ( P<0.001). HZ occurred throughout the year without marked seasonality. The incidence rate increased with age ( P<0.001). The incidence rate was higher in females than males (3.46‰ vs. 2.91‰, P<0.001) and also higher in Shaoxing than Zhoushan (3.38‰ vs. 1.87‰, P<0.001). Regarding complications, these occurred in 44.51% (20 157/45 280) of patients, with the most common complication being postherpetic neuralgia. The incidence rate of HZ with complications was lower than that without complications (1.41‰ vs. 1.76‰, P<0.001), but both hospitalization (0.14‰ vs. 0.03‰, P<0.001) and recurrence rates (27.43‰ vs. 6.69‰, P<0.001) were higher for cases with complications. Additionally, among individuals aged ≥40 years, the overall HZ vaccination rate was 1.42‰. Conclusion:Herpes zoster imposes a substantial disease burden in Zhejiang Province, while the vaccination rate remains low.

The rabies virus(RABV)that causes rabies mainly attacks the peripheral and central nervous systems.In the later stages of infection,it is scattered in the salivary glands and transmit-ted to other susceptible animals through infectious saliva.To study dispersion of the RABV in the three pairs of salivary gland tissues,the street strain PB4 of the RABV was inoculated into 21-day-old female mice through the hind limb muscles.During the moribund stage of the mice,the sublin-gual gland,submandibular gland and parotid gland were collected,respectively.The TCID50 titer of RABV in the three kinds of glands of the mice and the copy number of the RABV N gene were de-tected,and RABV in different salivary glands was observed by immunofluorescence.The results showed that PB4 was dispersed in all three kinds of salivary glands of the mice,with the largest a-mounts in the parotid gland,followed by the submandibular gland,and the lowest amount in the sublingual gland.Three-month-old dogs were inoculated with PB4 through the cranial cavity,and saliva were collected every 12 h after inoculation.The saliva samples were detected by TCID50 and RT-qPCR.And during the moribund stage of the dogs when the disease occurred,the three pairs of salivary glands were collected.Through the determination of the TCID50 titer,RT-qPCR and immu-nofluorescence detection,it was demonstrated that among the three different salivary glands of the dogs,the largest amount of PB4 was found in the parotid gland and the lowest in the sublingual gland.Our results in mice and dogs clearly proved that the parotid gland was consistently found to exhibit the highest content of street RABV among the three major salivary glands,which could en-rich experimental data for analyzing the dispersion of RABV in the salivary glands and interpreta-tion of the intermittent secretion of saliva in clinically rabid dogs.

OBJECTIVES: To establish a prognostic model for primary liver cancer (PLC) using bioinformatics methods. METHODS: Based on the data from 404 patients in the Cancer Genome Atlas (TCGA) database, we constructed a prognostic model integrating the differentially expressed genes, anoikis, and immune-related genes (DAIs) using univariate Cox regression and the LASSO-Cox approach. The predictive ability of the model was evaluated using Kaplan-Meier method and receiver-operating characteristic curves, and a nomogram was developed to facilitate its clinical applications. Gene set enrichment analysis (GSEA) was performed to explore the associated pathways and relationship between the DAIs and the tumor immune microenvironment, and the half-maximal inhibitory concentration (IC₅₀) of liver cancer drugs was calculated using the "pRRophetic" R package. We also detected the expression of SEMA7A in paired tumor and adjacent tissues from liver cancer patients. RESULTS: We constructed and validated a prognostic model based on 7 DAIs (NR4A3, SEMA7A, IL11, AR, BIRC5, EGF, and SPP1), and obtained consistent results in both the TCGA training cohort and GEO validation cohort (GSE14520), where the patients in the low-risk group were characterized by more favorable clinical outcomes and immune status. By integrating this prognostic signature with clinical information, a composite nomogram was generated. Somatic mutation analysis showed that TTN, TP53, and CTNNB1 mutations accounted for the largest proportion of total mutations, and the patients in the low-risk-low-TMB group had higher survival rate. Drug sensitivity analysis revealed differences in sensitivity to chemotherapeutic agents between high- and low-risk groups and between TP53 mutations and non-mutations. In clinical tissue specimens, SEMA7A expression was significantly higher in liver cancer tissues than in the adjacent tissues. CONCLUSIONS We established a new prognostic model based on DAIs for predicting clinical outcomes and therapeutic response of patients with primary liver cancer.

This study aims to inquire about the fluctuations of ubiquitin-specific protease 47 on neu-roblastoma cells(Neuro-2a,N2a)infected by rabies virus(RABV).USP47 expression levels were detected after RABV infection in N2a cells through RT-qPCR,protein immunoblotting,and virus titer determination.The levels of RABV nucleoprotein and phosphoprotein gene and protein,and RABV titers in supernatants were analyzed during overexpression and knockdown of USP47.The results showed that RABV infection increased USP47 gene level in N2a cells.When overexpression of USP47,the levels of RABV N and P were increased,and the virus titers were also improved.Mo-reover,the level of interleukin-6(IL-6)genes decreased.Knocking down USP47 expression reduced levels of RABV N and P genes and proteins,lowered the virus titer,and elevated the IL-6 gene lev-el.The results suggest that USP47 promotes RABV infection and suppresses IL-6 expression.This finding lays the foundation for further investigation into the molecular mechanisms by which USP47 regulates RABV infection.

Objective To investigate the factors influencing the natural outcome of low-grade squamous intraepithelial lesions(LSIL)of the cervix.Methods A total of 154 patients who underwent colposcopic cervical biopsy in the Third Affiliated Hospital of Zhengzhou University from January 2022 to January 2023 were selected and divided into negative conversion group(55 cases),continuous group(70 cases)and upgraded group(29 cases)according to the follow-up results.Logistic regression was used to analyze the influence of related factors on the outcome of LSIL.Results There were statistically significant differences in the number of vaginal births,the results of thin-prep cytology test,human papilloma virus(HPV)typing,whether vaginal LSIL was combined,whether there were symptoms,and vaginal microecology among three groups(P＜0.05).Multivariate Logistic analysis showed that combined vaginal LSIL,vaginal microecological abnormalities,atypical squamous cell-cannot exclude high-grade squamous intraepithelial lesion(ASC-H)/high-grade squamous intraepithelial lesion(HSIL),HPV 16/18 positive or mixed positive were independent risk factors for persistent infection(P＜0.05),combined vaginal LSIL,symptomatic,vaginal microecological abnormalities,ASC-H/HSIL,HPV 16/18 positive or mixed positive were all independent risk factors for escalation of lesions(P＜0.05).Conclusion Patients with vaginal LSIL,vaginal microecological abnormalities,ASC-H/HSIL,HPV 16/18 positive or mixed positive should be followed up and early intervention to reduce the risk of disease escalation.

To establish a highly specific,sensitive,and efficient method for detecting antibodies a-gainst the Erns protein of classical swine fever virus(CSFV),and to distinguish CSFV vaccine strains from wild strains infections in combination with the E2 subunit vaccine.The purified Erns protein of the CSFV expressed by baculovirus was conjugated to carboxylated magnetic beads as a solid-phase carrier and horseradish peroxidase(HRP),separately.A double-antigen sandwich chemiluminescent enzyme immunoassay(CLEIA)was developed by optimizing various reaction parameters using a fully automated chemiluminescence analyzer.This method was then applied to quantitatively detect Erns protein antibodies in sera from pigs infected with prevalent strains and those immunized with the CSFV E2 subunit vaccine and challenged with field strains.The results showed that the optimal conditions for coupling protein-to-magnetic bead were as follows:coupling buffer pH of 8.0,a protein coupling amount of 2.5 mg/g,blocking solution of 10％BSA,serum sample volume of 20 μL.The optimal dilution of enzyme-labeled antigen was at 1:500 with a one-step reaction time of 15 minutes.The cutoff value of the established CLEIA method for detecting CSFV Erns protein antibodies was 5.83 U/mL and a diagnostic sensitivity of 1:128.No cross-reac-tivity was observed with positive sera against African swine fever virus,pseudorabies virus,porcine circovirus type 2,porcine epidemic diarrhea virus,porcine reproductive and respiratory syndrome virus,or porcine gastroenteritis virus.Additionally,the method yielded negative results with sera from pigs immunized with the E2 subunit vaccine.In repeatability tests,the intra-assay coefficient of variation(CV)ranged from 0.77％to 11.56％,and the inter-assay CV ranged from 10.30％to 14.55％,both below 15％.The positive and negative concordance rates with a commercial CSFV Erns protein antibody detection kit were 95.24％and 92.71％,separately,with an overall concord-ance rate of 93.23％.The double-antigen sandwich chemiluminescence method established in this study exhibits high sensitivity,excellent repeatability,and suitability for automated detection,making it applicable for serological differentiation between CSFV E2 subunit vaccination and infec-tion with prevalent strains.
