Objective To summarize the clinical characteristics and analyze prognostic factors of neuroblastoma (NB) in infants (≤12 months) at a single center. Methods A retrospective analysis was conducted on the clinical data of infant patients (≤12 months) diagnosed with NB and treated between January 2014 and December 2022. Clinical features were analyzed, and comparisons between two sample rates were performed using the χ² test. Univariate prognostic analysis was conducted using the log-rank test, and survival outcomes were analyzed using the Kaplan-Meier method. Results A total of 42 infants (≤12 months) with NB were enrolled. Low-risk patients underwent surgical resection alone; intermediate-risk patients received surgery combined with chemotherapy with or without maintenance therapy; high-risk patients were treated with surgery and chemotherapy with or without maintenance therapy or radiotherapy. The 5-year event-free survival (EFS) rate was (92.7±4.9)%, and the 5-year overall survival rate was (95.2±3.6)%. Only two patients died because of tumor recurrence or progression. Univariate analysis identified MYCN amplification and the initial lactate dehydrogenase (LDH) level ≥ five times the upper limit of the normal were significantly associated with poor prognosis (5-year EFS: 33.3% vs. 97.4% and 60.0% vs. 97.3%, P<0.0001 and P=0.0035). Conclusion Infant NB has a favorable overall prognosis. MYCN amplification and markedly elevated initial LDH are associated with poor outcomes.

Objective: To determine the association between exposure to entertainment screen content on mobile phones and symptoms of anxiety-depression co-morbidity among college students,so as to provide evidence for mental health interventions. Methods: A baseline survey was conducted from April to May 2019. A total of 1 135 college students were selected from one university each in Shangrao City, Jiangxi Province and Hefei City, Anhui Province using cluster random sampling method. A follow up study was conducted in November 2019, resulting in 1 110 matched valid responses. Self rating questionnaires were used to assess the exposure of entertainment screen content. The Depression Anxiety Stress Scale-21(DASS-21) and the Patient Health Questionnaire-9 (PHQ-9) were used to evaluate the anxiety symptoms, depressive symptoms, and symptoms of anxiety-depression co-morbidity among college students. A multivariate binary Logistic regression model was constructed following initial intergroup comparisons with Chi-square test to determine the association between baseline exposure to mobile entertainment screen content and the risk of symptoms of anxiety depression co-morbidity at baseline and the 6 month follow up. Results: The prevalence rates of symptoms of anxiety-depression co-morbidity among college students were 25.4% and 20.6% at baseline and follow up, respectively.After adjusting for confounding factors such as gender, self rated family economic status and self rated health status, the results of multivariate binary Logistic regression analysis showed that compared with the appropriate exposure level group, the exposure of entertainment screen content on mobile phones at baseline, including frequent exposure to reading( OR =1.65,95% CI =1.14-2.39), occasional exposure to other entertainment screen content ( OR =1.46,95% CI =1.01-2.10)and frequent exposure to other entertainment screen content( OR =1.76,95% CI =1.20-2.60), increased the co-occurrence risk of symptoms of anxiety-depression co-morbidity among college students during the follow up period (all P <0.05). Conclusion Occasional or frequert exposure to mobile entertainment screen content can increase the risk of symptoms of anxiety depression co-morbidity among college students.

ObjectiveThis study aimed to investigate whether Bushen Tongluo prescription inhibits macrophage polarization by regulating the Wnt3a/β-catenin signaling pathway， thereby reducing epithelial-mesenchymal transition and excessive extracellular matrix deposition， in order to elucidate the anti-pulmonary fibrosis mechanisms of Bushen Tongluo prescription and provide a new theoretical basis for the clinical treatment of pulmonary fibrosis. MethodsFifty male Sprague-Dawley （SD） rats were randomly divided into a blank group， model group， pirfenidone group， and high- and low-dose Bushen Tongluo prescription groups. Except for the blank group， the pulmonary fibrosis model was established by intratracheal instillation of bleomycin. Intervention was initiated on day 28 after modeling. The high- and low-dose Bushen Tongluo prescription groups were administered Bushen Tongluo prescription at doses of 30.88， 15.44 g·kg^-1， respectively， by intragastric gavage. The pirfenidone group was administered pirfenidone capsules at 110 mg·kg^-1 by intragastric gavage. The blank and model groups were given an equal volume of normal saline by gavage， once daily for 90 days. After treatment， the level of transforming growth factor-β₁ （TGF-β₁） in bronchoalveolar lavage fluid （BALF） was detected by enzyme-linked immunosorbent assay （ELISA）. Morphological changes in lung tissue and the collagen volume fraction were compared. The protein distribution and expression of E-cadherin， cytokeratin 19， α-smooth muscle actin （α-SMA）， vimentin， collagen type Ⅰ （Col Ⅰ）， and collagen type Ⅲ （Col Ⅲ） in lung tissue were detected by immunohistochemistry. The protein distribution and expression of CD68， arginase-1 （Arg-1）， inducible nitric oxide synthase （iNOS）， Wnt3a， and β-catenin in lung tissue were detected by immunofluorescence. The protein expression of Wnt3a and β-catenin in lung tissue was detected by Western blot， and the mRNA expression of Wnt3a and β-catenin was detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. ResultsCompared with the blank group， a large number of inflammatory cells infiltrated the airway walls， alveolar spaces， and interstitial tissue in the model group， with obvious fibrous tissue hyperplasia. The level of TGF-β₁ in BALF was significantly increased. The protein expression of E-cadherin and cytokeratin 19 in lung tissue was decreased， whereas the protein expression of α-SMA， Vimentin， Wnt3a， β-catenin， Col Ⅰ， and Col Ⅲ was increased. The fluorescence-positive area ratios of CD68， Arg-1， iNOS， Wnt3a， and β-catenin in lung tissue were increased. The protein and mRNA expression levels of Wnt3a and β-catenin in lung tissue were significantly increased （P<0.01）. Compared with the model group， all treatment groups showed varying degrees of improvement in inflammatory cell infiltration and fibrous tissue hyperplasia in the airway walls， alveolar spaces， and interstitial tissue， decreased TGF-β₁ levels in BALF， increased protein expression of E-cadherin and cytokeratin 19 in lung tissue， decreased protein expression of α-SMA， Vimentin， Col Ⅰ， and Col Ⅲ， decreased fluorescence-positive area ratios of CD68， Arg-1， iNOS， Wnt3a， and β-catenin in lung tissue， and decreased protein and mRNA expression levels of Wnt3a and β-catenin in lung tissue （P<0.05， P<0.01）. ConclusionBushen Tongluo prescription can improve bleomycin-induced pulmonary fibrosis in rats by inhibiting epithelial-mesenchymal transition and reducing excessive extracellular matrix deposition. The mechanism may be related to inhibition of the Wnt3a/β-catenin signaling pathway and the macrophage polarization mediated by this pathway.

Objective: To systematically analyze the confirmatory positivity of different combinations of HBsAg screening results in blood testing, providing data to support the optimization of blood donor eligibility management. Methods: A retrospective analysis was conducted on blood screening data from 174 266 voluntary blood donor samples at the Chongqing Blood Center between October 2021 and September 2022. Samples with inconsistent results between the two HBsAg enzymelinked immunosorbent assays (ELISA) and individual donor nucleic acid testing (NAT) were confirmed using an electrochemiluminescence immunoassay (ECLIA) and a neutralization test. The detection efficacy of four different HBsAg ELISA reagents was compared using the HBsAg-confirmed positive samples. Results: A total of 767(0.44%) HBV-reactive (HB-sAg and/or HBV DNA reactive) samples were detected. Among them, 344 samples with discordant serological and NAT results were collected, of which 64(18.6%) were confirmed positive by neutralization test. Additionally, 5 samples that were neutralization-negative but double-reactive for HBsAg and HBV DNA were confirmed as positive according to FDA guidance, resulting in a total of 69(20.1%) confirmed HBsAg-positive samples. There were significant differences in the neutralization test confirmation rates among different screening result categories (P<0.05): The group with dual HBsAg reagent reactivity (double reactive) & NAT-negative had the highest confirmation rate (96.9%, 31/32); the group reactive to only reagent 2 (single reactive) had a rate of 25.7% (29/113); while the confirmation rates for samples reactive to only reagent 1 and samples with isolated HBV DNA positivity were extremely low [0(0/34) and 2.4%(4/165), respectively]. The four commercial reagents showed significant differences in their ability to detect confirmed positive samples that were initially single reactive (P<0.05). Conclusion: Given the performance variations among HBsAg screening reagents, thorough performance verification is essential before implementation. When NAT is negative, dual HBsAg reactivity in screening can serve as a basis for confirming infection and directly deferring blood donors. However, confirming infection in donors with single HBsAg reactivity is more challenging, necessitating supplementary tests to rule out infection risk.

Objective:To analyze the associated factors and cumulative effects of cardiometabolic multimorbidity (CMM) among residents in southern Xinjiang.Methods:A stratified random cluster sampling method was used to conduct questionnaire surveys, physical examinations and laboratory tests among the personnel of the 51st Brigade, 3rd Division, Xinjiang, in 2016. The multivariate logistic regression, multivariate linear regression, restricted cubic spline, and network analysis methods were used to study the association of lifestyle (smoking, alcohol consumption and physical activity), socioeconomic (occupation, education and marital status) and clinical factors (waist circumference, body mass index and family history) with CMM.Results:A total of 12 773 study subjects were included. The prevalence of cardiovascular metabolic diseases among residents in southern Xinjiang was 52.49%. Specifically, the prevalence rates of dyslipidemia, hypertension, coronary heart disease, diabetes, and stroke were 31.14%, 29.95%, 6.78%, 6.26%, and 2.47%, respectively, and the prevalence of CMM was 19.06%. Multivariate logistic regression analysis revealed that the associations between clinical and socioeconomic factors and CMM significantly increased with higher scores. Specifically, the OR rose from 1.75 (clinical factors) and 1.07 (socioeconomic factors) on a score of 1 to 4.41 and 1.93 on a score of 3, respectively. The association between lifestyle factors and CMM was only observed at higher scores ( OR=1.26, 95% CI:1.07~1.62). The trend test using the scores of each group as continuous variables in the model showed that the risk of disease increased with the accumulation of clinical, socioeconomic and lifestyle factors (all P<0.05). Restricted cubic spline analysis demonstrated a non-linear relationship between the total number of associated factors and CMM ( Poverall<0.05 and Pnon-linear<0.05). Network analysis identified hypertension (strength=0.42) as the “core node” among the five diseases. When analyzing the three types of influencing factors, hypertension (strength=0.68), dyslipidemia (strength=0.47), coronary heart disease (strength=0.37), and clinical factors (strength=0.53) emerged as “core nodes”. In the network of nine associated factors, abnormal waist circumference and BMI (strength=0.90 and 0.84) were identified as “key factors”, while hypertension (strength=0.68) and dyslipidemia (strength=0.52) were identified as “key diseases”. Conclusion:The prevalence of CMM among residents in southern Xinjiang is high, and there is a cumulative effect of multiple factors. Hypertension and dyslipidemia are key diseases in the multimorbidity network, while abnormal BMI and waist circumference are key associated factors.

Objective:To explore effect of Astragalus polysaccharides(APS)through TLR4/NF-κB signal pathway on intesti-nal immune inflammation of rats with dampness stagnancy due to spleen deficiency syndrome based on fecal microbiota transplantation.Methods:Rats with dampness stagnancy due to spleen deficiency syndrome were fed with high-fat and low-protein diet and subjected to exhaustive swimming,transplant flora microbiota after intervention of APS.General condition,changes in weight gain,time of weight exhaustion swimming,spleen index and thymus index were tested.Pathological manifestations of duodenal tissue inflammation were observed by HE staining.Serum IL-1β,IL-6 and TNF-α concentrations of rats were determined by ELISA.Protein levels of TLR4,NF-κB p65 and IκBα in colon were determined by Western blot.Results:Compared with model group,general condition rating,changes in weight gain and time of weight exhaustion swimming in APS-FTG group were increased significantly(P<0.01);spleen index and thymus index were increased;pathological manifestations of duodenal inflammation were significantly relieved;serum IL-1β,IL-6 and TNF-α concentrations were decreased significantly(P<0.01),TLR4 and NF-κB p65 levels in colon were decreased significantly(P<0.05 and P<0.01),IκBα level was in colon increased significantly(P<0.01).Conclusion:APS improves intestinal microbiota of rats with dampness stagnancy due to spleen deficiency syndrome and inhibits TLR4/NF-κB pathway activation through intestinal flora,thus improving intestinal immune inflammation status in rats with dampness stagnancy due to spleen deficiency syndrome.

Objective To explore curative effect of two thrombolytic regimens in the treatment of ultra-early acute cerebral infarction(ACI)of different age groups and different thrombolytic time windows.Methods A total of 166 patients with ACI were enrolled,with interval from onset to treatment≤4.5 h.According to different thrombolytic regiments,patients were divided into the recombinant tissue plasminogen activator(rt-PA)group(104 cases,intravenous thrombolysis with 0.9 mg/kg rt-PA)and the tenecteplase(TNK)group(62 cases,intravenous thrombolysis with 0.25 mg/kg TNK).According to different age groups and different thrombolytic time windows,patients were divided into the high age group(≥70 years),the low age group(＜70 years),the short time window group(＜3 h)and the long time window group(3-4.5 h).After thrombolysis,laboratory indexes[neutrophil(NEU),lymphocyte(LYM)],scores of National Institutes of Health Stroke Scale(NIHSS),modified Rankin scale(mRS)and incidence of adverse events were compared in different groups by factorial analysis method.Results There was no significant difference in any index between the rt-PA group and the TNK group(P＞0.05).Compared with the high age group at 7 d after thrombolysis,NIHSS score,NEU,neutrophil to lymphocyte ratio(NLR)and high sensitive C-reactive protein(hs-CRP)were lower,while LYM and albumin(ALB)were higher in the low age group(P＜0.05).Compared with the long time window group,NEU and NLR were lower,while LYM was higher in the short time window group(P＜0.05).There was no significant difference in total incidence of adverse events within 14 d of thrombolysis between the different age groups and the different thrombolytic time window groups(P＞0.05).Conclusion For patients with ultra-early ACI,0.9 mg/kg rt-PA and 0.25 mg/kg TNK have comparable efficacy in intravenous thrombolysis,and both have better effects when patient age is＜70 years old and the thrombolysis time window is＜3 hours.

This article presents a case study of a patient who visited the Geriatric Department of Peking Union Medical College Hospital due to "palpitations, shortness of breath for more than 2 years, limb weakness for 6 months, edema, and nocturnal dyspnea for 2 months". The patient exhibited decreased muscle strength in the limbs and involvement of swallowing and respiratory muscles, alongside complications of heart failure and various arrhythmias which were predominantly atrial. Laboratory tests revealed the presence of multiple autoantibodies and notably anti-mitochondrial antibodies. Following a comprehensive multidisciplinary evaluation, the patient was diagnosed with anti-mitochondrial antibody-associated inflammatory myopathy. Treatment involved a combination of glucocorticoids and immunosuppressants, along with resistance exercises for muscle strength and rehabilitation training for lung function, resulting in significant improvement of clinical symptoms. The case underscores the importance of collaborative multidisciplinary approaches in diagnosing and treating rare diseases in elderly patients, where careful consideration of clinical manifestations and subtle abnormal clinical data can lead to effective interventions.

Objective:To assess the diagnostic performance of a panel of autoantibodies against multiple tumor-associated antigens (BRCA2, P53, ANXA11, PARP1, TRIM21, ATAD2, NY-ESO-1 and CAGE) in the detection of breast cancer.Methods:This was a retrospective case-control study. A total of 545 patients diagnosed with breast cancer (BC) by pathological examination, and eligible for enrolment at Jiangsu Cancer Hospital from January 2022 to December 2023 were selected as the patient group. In the same period, 200 patients with benign breast disease (BD) and 200 healthy individuals (HC) were included. Enzyme-linked immunosorbent assay (ELISA) was used to detect the serum levels of tumor-associated autoantibodies in each group. The tumor markers including carcinoembryonic antigen (CEA), glycoconjugate antigen 125 (CA125) and glycoconjugate antigen 153 (CA153) were detected using electrochemiluminescence. Univariate and multivariate logistic regression analyses were used to screen the factors associated with breast cancer. The receiver operating characteristic (ROC) curve was applied to evaluate diagnostic value.Results:The levels of seven autoantibodies against BRCA2, P53, ANXA11, PARP1, ATAD2, NY-ESO-1 and CAGE were significantly higher in the BC group compared to HC group (all P<0.05). Additionally, the levels of six autoantibodies against BRCA2, P53, PARP1, ATAD2, NY-ESO-1 and CAGE were significantly higher in the BC group than those in BD group (all P<0.05). The levels of PARP1 and ATAD2 in the BD group were higher than those in HC group ( P<0.05). Logistic multivariate analysis revealed that BRCA2 ( OR=1.099, 95% CI 0.824-1.107), P53 ( OR=1.534, 95% CI 0.813-2.898), NY-ESO-1( OR=1.159, 95% CI 0.789-1.712) and CA153 ( OR=1.029, 95% CI 0.778-1.495) were potential indicators for breast cancer (all P<0.05). The ROC curves indicated that the AUCs for breast cancer using BRCA2, P53, NY-ESO-1, and CA153 were 0.602 (95% CI 0.549-0.635), 0.688 (95% CI 0.642-0.734), 0.729 (95% CI 0.677-0.781), 0.714 (95% CI 0.663-0.764), respectively. The sensitivities were 0.405, 0.588, 0.683 and 0.653, while the specificities were 0.770, 0.825, 0.851 and 0.790, respectively. The AUC of the combined detection including BRCA2, P53, NY-ESO-1, and CA153 for breast cancer was 0.857 (95% CI 0.832-0.883), with a sensitivity of 0.719 and a specificity of 0.835. Conclusions:The levels of tumor-associated autoantibodies to BRCA2, P53 and NY-ESO-1 were significantly elevated in breast cancer patients, and the combination of the three autoantibodies and CA153 has high diagnostic value for breast cancer.
