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.

ObjectiveTo observe the effect of Qishao capsules on renal injury in db/db mice with diabetic kidney disease （DKD），and explore its mechanism of protecting the kidney by inhibiting podocyte apoptosis. Methodsdb/m mice （7 mice） were used as the normal group，and db/db mice （35 mice） were randomly divided into a model group，a dapagliflozin group （0.001 g·kg^-1·d^-1），and low-，medium-，and high-dose groups of Qishao capsules （0.341 3，0.682 5，and 1.365 g·kg^-1·d^-1，respectively）. Drug intervention lasted for 8 consecutive weeks. After sampling，the serum renal function indicators ［creatinine（SCr），and urea nitrogen（BUN）］，fasting blood glucose （FBG），24 h urinary protein quantification （24 h-UTP）， and other indicators of the mice were measured. The pathological tissue morphology of the kidney was observed by periodic acid-silver methenamine （PASM） and Masson's trichrome （Masson） staining. Immunohistochemical detection of cysteine-dependent aspartate-specific protease （Caspase）-3 and B-cell lymphoma 2 （Bcl-2） was performed. Western blot was used to detect the protein expression of Caspase-8，Caspase-7，Caspase-3， and other molecules. Terminal deoxynucleotidyl transferase dUTP nick End labeling （TUNEL） staining was used to observe apoptosis in renal tissue. Immunofluorescence staining of Wilms tumor suppressor gene-1 （WT-1） was used to observe podocyte injury. Real-time polymerase chain reaction （Real-time PCR） was employed to detect Caspase-8 and Caspase-3 mRNA expression in the kidneys of experimental mice. Data analysis was conducted using statistical software GraphPad Prism 10. ResultsCompared with the normal group，the model group showed significantly increased 24 h-UTP，SCr，BUN，and FBG （P<0.01）. Additionally， PASM staining of renal tissue showed increased glycogen deposition，glomerular hypertrophy，and thickening of the basement membrane. Masson staining showed collagen fiber proliferation in renal tissue. Transmission electron microscopy showed thickening of the renal tissue basement membrane and fusion or loss of foot processes in the model group. The immunohistochemical results showed that Caspase-3 in the kidneys of the mice in the model group significantly increased （P<0.01），while the Bcl-2 protein expression level decreased significantly （P<0.01）. The number of TUNEL positive cells in renal tissue significantly increased （P<0.01）. The positive expression of WT-1 in podocytes was significantly reduced （P<0.01）. Western blot analysis showed significant upregulation of Caspase-8，Caspase-7，and Caspase-3 protein expression in renal tissue （P<0.01）. The mRNA expression levels of Caspase-8 and Caspase-3 in the kidneys increased significantly （P<0.01）. Compared with the model group，the Qishao capsules groups can significantly reduce the levels of 24 h-UTP，SCr，BUN，and FBG （P<0.01）. The pathological damage of renal tissue and podocyte injury were improved to some extent. Immunohistochemistry in the kidney showed a significant decrease in Caspase-3 （P<0.01） and a significant increase in Bcl-2 protein expression level （P<0.01）. Additionally， there were a significant decrease in the number of TUNEL positive cells in renal tissue （P<0.01），a significant increase in WT-1 positive expression in podocytes （P<0.01），marked downregulation of Caspase-8，Caspase-7，and Caspase-3 protein expression in renal tissue （P<0.05，P<0.01），and a significant decrease in Caspase-8 and Caspase-3 mRNA expression levels （P<0.01）. ConclusionQishao capsules can inhibit podocyte apoptosis by regulating the expression of Caspase-8，Caspase-7， and Caspase-3，thereby improving the diabetic renal injury in db/db mice.

Objective To investigate the association between plasma homocysteine(Hcy)level and coronary artery calcification(CAC)and its clinical predictive efficacy.Methods A total of 172 patients who underwent coronary CT angiography North China University of Science and Technology Affiliated Hospital from April 2019 to May 2021 and CAC score(CACS)＞0 were enrolled.According to the CACS value,the subjects were divided into mild calcification group(n=136)and severe calcification group(n=36),and the clinical characteristics of two groups were compared and analyzed.Multivariate Logistic regression model was used to screen the independent influencing factors of CAC severity,and a prediction model was constructed based on the Hcy detection value.The clinical diagnostic value was evaluated by the receiver operating characteristic(ROC)curve.Results There were significant differences in Hcy,white blood cell count,triglyceride and magnesium ion levels between two groups(P＜0.05).Multivariate Logistic regression analysis showed that Hcy,white blood cell count and magnesium ion level were independent risk factors for the progression of CAC.Furthermore,a regression model based on Hcy was constructed and ROC curve was fitted to evaluate its predictive efficacy.The results suggested that the predictive model had the best performance when the critical value of Hcy was set at 27.4μmol/L:the sensitivity was 55.6％,the specificity was 97.1％,and the area under the curve was 0.765.Conclusion Hcy serves as an independent risk factor for the severity of CAC and can effectively predict the progression of CAC with high accuracy.

Objective To construct an assay for early infection diagnosis of Angiostrongylus cantonensis based on gold nanorod polymerization.Methods Stable gold nanorods were synthesized by the gold seed growth method,and labeled with different concentrations of sulfhydrylated crude and purified antigens of lar-vae and adults of Angiostrongylus cantonensis,and their excretory and secretory antigens,and then scanned the longitudinal surface plasmon resonance(LSPR)of the stable gold nanorods by ultraviolet-visible(UV-Vis)spectrophotometry,and screened for the optimal labeled antigens for the detection of different infection time after infection of rats with Angiostrongylus cantonensis.The displacement changes were screened to se-lect the best labeled antigens for the detection of serum antibodies and positive sera of series of dilution gradi-ents at different infection times(5,7,14,21 d)after infection with Angiostrongylus cantonensis in rats,and at the same time,the enzyme-linked immunosorbent assay(ELISA)was set up for the same test.Kappa test was used to compare the consistency of the two assays.Results Gold nanorods with stable aspect ratio were suc-cessfully prepared.The gold nanorods labeled with 10 μg/mL of adult purified antigen had a maximum LSPR shift of 40 nm,and were able to detect serum antibodies in rats 5 d after mild,moderate and severe infection with Angiostrongylus cantonensis,as well as positive sera at a maximum dilution of 1∶600.The ELISA was able to detect serum antibodies in rats after 14 d of mild infection,and 7 d of moderate and severe infection,as well as positive sera at a maximum dilution of 1∶200.The ELISA detected positive serum antibodies in rats after 14 d of mild infection and 7 d of moderate and severe infection,as well as in rats at a maximum dilution of 1∶200.The Kappa value of the two methods was 0.750(P<0.01),and the results of the two methods had strong consistency.Conclusion A polymerized gold nanorod assay for early and rapid diagnosis of An-giostrongylus cantonensis infection is successfully constructed.

Objective To explore the traditional Chinese medicine(TCM)syndrome characteristics of patients with Chikungunya hemorrhagic fever and to provide empirical data to support the application of TCM in diagnosing and treating Chikungunya hemorrhagic fever.Methods A cross-sectional survey was conducted to collect clinical data(sex,age,days since onset,and comorbidity underlying disease conditions)and TCM with four-examination information(symptoms,tongue manifestations,and pulse manifestations)from 255 patients with Chikungunya hemorrhagic fever who visited Lecong Hospital of Shunde,Foshan,the Third People's Hospital of Shunde District of Foshan,Shunde Hospital of Southern Medical University Affiliated Chencun Hospital between July 23 and July 29,2025.Factor and cluster analyses were used to summarize TCM syndrome characteristics and analyze core pathogenesis in conjunction with clinical features.Results Among the 255 patients with Chikungunya hemorrhagic fever,131 were male and 124 were female,with a age of(49.05±17.93)years and a disease duration of(3.26±1.78)days.Among the four types of examination information in TCM,35 items exhibited a frequency exceeding 10%.The most prevalent symptoms were arthralgia(180 patients,70.59%),exanthem(153 patients,60.00%),fatigue(99 patients,38.82%),anhidrosis(98 patients,38.43%),pruritus(96 patients,37.65%),and fever(92 patients,36.08%).Tongue and pulse manifestations were primarily white fur(155 patients,60.78%),pink tongue(111 patients,43.53%),slippery pulse(143 patients,56.08%),and greasy fur(134 patients,52.53%).Patients with disease onset≤3 d had a higher incidence of arthralgia,fatigue,fever,aversion to cold,generalized muscle pain,aversion to wind,insomnia,headache,sweating,low-grade fever,poor appetite,loose stool,hyperhidrosis,and red tongue than those with disease onset≥4 d(P<0.05).Patients with disease onset≥4 d had a higher incidence of pink tongue and thick fur than those with disease onset≤3 d(P<0.05).The syndrome elements in patients with Chikungunya hemorrhagic fever predominantly manifested on the defensive exterior,with involvement of the sinew-bone joints,skin-muscle,and spleen.Pathogenic factors were primarily characterized by external winds,dampness,and heat.Factor and cluster analysis result indicated three TCM pathogenesis progression patterns:imbalance of the defensive exterior with wind-dampness conflict and heat transformation;dampness-heat flowing into muscles and meridians causing joint obstruction and qi blood stasis;and dampness-heat congelation resulting in qi mechanism obstruction,consumption of body fluids,and infiltration of the skin.Conclusion Patients with Chikungunya hemorrhagic fever primarily present with fever,joint pain,and rashes.In TCM,this condition falls under the category of"dampness-warmth"syndrome.Its etiology is attributed to pathogens,with transmission occurring through mosquito bites.The core pathogenesis of TCM is the invasion of the defensive exterior and dampness-toxic heat accumulation.The therapeutic principles focus on clearing heat pathogens,resolving dampness pathogens,dispersing wind pathogens,and promoting the resolution of rashes.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.
