To investigate the risk factors for acute kidney injury (AKI) following the use of amphotericin B deoxycholate and to develop a predictive model to guide clinical monitoring and intervention. A retrospective analysis was conducted on hospitalized patients who received amphotericin B deoxycholate between January 2014 and September 2024. Patients were divided into a training set and a validation set. Demographic data, laboratory findings, and medication orders were collected. Based on the occurrence of AKI during treatment and within 7 days after discontinuation, patients were classified into an AKI group and a non-AKI group. Univariate analysis was used to screen for potential risk factors, multivariate logistic regression was employed to construct a predictive model, and model performance was evaluated using the area under the receiver operating characteristic curve (AUC) and the Hosmer-Lemeshow test. The training set included 473 patients, comprising 255 males (53.91%) and 218 females (46.09%), with a median age of 52(35, 62) years. The AKI group consisted of 191 cases (40.38%), and the non-AKI group consisted of 282 cases (59.62%). The validation set included 114 patients, comprising 80 males (70.18%) and 34 females (29.82%), with a median age of 43.5 (31.0, 58.5) years. The AKI group consisted of 42 cases (36.84%), and the non-AKI group consisted of 72 cases (63.16%). Univariate analysis revealed statistically significant differences between the two groups in 23 factors (all Admission to the ICU, elevated serum creatinine at admission, and comorbid cardiac insufficiency as potential risk factors for AKI, while prophylactic use of diphenhydramine/promethazine or sodium bicarbonate showed a protective association. A predictive model with good discrimina-tion and calibration was developed, which may provide a basis for early identification of high-risk patients and timely adjustment of treatment strategies in clinical practice.

Objective To investigate the efficacy of preoperative nebulized indocyanine green (ICG)-assisted thoracoscopic anatomical lesion resection (TALR) in treating pediatric congenital pulmonary airway malformation (CPAM). Methods A retrospective analysis was conducted on clinical data of 45 children with CPAM who underwent thoracoscopic surgery at the Third Affiliated Hospital of Zhengzhou University between June 2023 and March 2025. The patients were divided into an ICG group (preoperative nebulized ICG 0.5 mg/kg+TALR) and a non-ICG group (TALR under white light), with perioperative and postoperative recovery parameters compared between groups. Results A total of 45 children [22 males, 23 females; median age 7.4 (1.1-75.0) months] were enrolled. The ICG group (n=22) and non-ICG group (n=23) both achieved uneventful recoveries. Compared to the non-ICG group, the ICG group demonstrated significantly shorter surgical duration [91.3 (38.0-144.0) min vs. 100.0 (50.0-175.0) min, P=0.032], reduced intraoperative blood loss [3.0 (2.0-10.0) mL vs. 5.0 (1.0-10.0) mL, P=0.049], shorter postoperative drainage duration [2.7 (1.9-3.9) d vs. 3.4 (1.8-19.9) d, P=0.003], and shortened hospital stay [4.6 (2.9-9.8) d vs. 5.0 (3.9-21.5) d, P=0.013]. Residual lesions occurred in 2 patients from the non-ICG group but none in the ICG group. Intragroup comparisons revealed significant improvements in ratio of time to peak tidal expiratory flow to expiratory time, ratio of volume to peak tidal expiratory flow to expiratory volume, and tidal volume per kilogram after surgery in both groups (P<0.05), though intergroup differences showed no statistical significance (P>0.05). Conclusion Preoperative nebulized ICG administration facilitates lesion identification in CPAM, reduces technical difficulty of TALR, enhances therapeutic outcomes, and provides valuable assistance for performing TALR procedures.

ObjectiveTo explore the therapeutic effect and mechanism of Huangqi Xiayuxue decoction against hepatocellular carcinoma based on network pharmacology, animal experiments, and cell experiments. MethodsThe active ingredients and corresponding targets of Huangqi Xiayuxue decoction were screened via databases including the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine (BATMAN-TCM). Hepatocellular carcinoma-related targets were retrieved from the GeneCards database. The common targets shared by Huangqi Xiayuxue decoction and hepatocellular carcinoma were subjected to Gene Ontology (GO) functional annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. Huangqi Xiayuxue decoction-containing plasma was prepared. The cell counting kit-8 (CCK-8) assay was adopted to observe the effects of different volume fractions (5%, 10%, 15%, and 20%) of Huangqi Xiayuxue decoction-containing plasma on the proliferation of HepG2, MHCC-97H, Hepa1-6, and Huh-7 cells, and the concentration for subsequent experiments was determined. Flow cytometry was adopted to detect the effects of Huangqi Xiayuxue decoction-containing plasma (5%, 10%, 15%, and 20%) on the apoptosis of MHCC-97H cells. A mouse model of subcutaneous xenograft hepatocellular carcinoma was established. The model mice were assigned into low-, medium-, and high-dose (4.63, 9.25, 18.5 g·kg-1) Huangqi Xiayuxue decoction and sorafenib (20 mg·kg-1) groups. Body mass and tumor volume of mice were dynamically monitored during the intervention period. After 3 weeks of intervention, hematoxylin-eosin (HE) staining was performed to observe tumor morphology. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay was employed to detect cell apoptosis. Immunohistochemistry (IHC) was adopted to examine the expression of cysteinyl aspartate-specific proteinase-3 (Caspase-3), B-cell lymphoma-2 (Bcl-2), and Bcl-2-associated X protein (Bax) in the tumor tissue. Real-time PCR and Western blot were employed to verify the changes in apoptosis-related factors and the phosphatidylinositol 3-kinase/protein kinase B/forkhead box O1 (PI3K/Akt/FoxO1) signaling pathway. ResultsA total of 220 common targets shared by Huangqi Xiayuxue decoction and hepatocellular carcinoma were screened out by network pharmacology, among which tumor protein p53 (TP53), Akt1, and signal transducer and activator of transcription 3 (STAT3) were the core targets. Pathway enrichment analysis indicated that the common targets were involved in cell apoptosis and proliferation, as well as the PI3K/Akt and FoxO signaling pathways. Cell experiments showed that compared with the blank plasma group, all volume fractions of Huangqi Xiayuxue decoction-containing plasma inhibited the proliferation of HepG2, MHCC-97H, Hepa1-6, and Huh-7 cells (P<0.01). The proportion of early apoptotic cells in MHCC-97H cells was increased after treatment with different volume fractions of Huangqi Xiayuxue decoction-containing plasma (P<0.01). Animal experiments revealed that Huangqi Xiayuxue decoction inhibited the growth of tumor volume, promoted tumor cell apoptosis in the high-dose group, up-regulated the protein and mRNA levels of Bax and Caspase-3, down-regulated the protein and mRNA levels of Bcl-2, and reduced the phosphorylation level of the PI3K/Akt/FoxO1 signaling pathway (P<0.05, P<0.01). ConclusionHuangqi Xiayuxue decoction exerts anti-hepatocellular carcinoma effects by inhibiting the activation of the PI3K/Akt/FoxO1 signaling pathway and promoting hepatocellular carcinoma cell apoptosis.

This study aims to analyze the screening results and epidemiological characteristics of prostate cancer (PCa) among elderly males in the rural areas of Songjiang, Shanghai City, through the implementation of a preliminary prostate-specific antigen (PSA) screening based on a community-linkage model, and to explore an effective screening approach. A retrospective observational study design was employed to collect data from residents who underwent PSA screening at Songjiang Hospital affiliated to Shanghai Jiao Tong University School of Medicine, in collaboration with multiple community health service centers in Songjiang District, Shanghai City, between June 2022 and June 2024, through free clinics and annual health examinations. Prostate biopsy was recommended for individuals with total PSA (tPSA) levels >10 ng/ml and those with 4 ng/ml≤tPSA≤10 ng/ml and abnormal free-to-total PSA (f/tPSA) ratios. Clinical characteristics of detected PCa patients were analyzed. Follow-up was conducted through phone calls and home visits by family doctors, coupled with enhanced health education. The results indicated that a total of 17 198 residents participated in the screening, among which 2 234 (12.99%) had tPSA levels between 4 ng/ml and 10 ng/ml, and 257 (1.49%) had tPSA levels >10 ng/ml. Ultimately, 417 residents underwent prostate biopsy, with 171 being diagnosed with PCa, yielding a positive biopsy rate of 41.00% and a PCa detection rate of 0.99%. The predominant pathological subtype among PCa patients was adenocarcinoma (168 cases, 98.24%). Of the 146 PCa patients who received treatment, the majority were classified as intermediate or high-risk (124 cases, 84.93%). Furthermore, with the optimization of the screening model, there was a significant increase in the proportion of subsequent outpatient visits. In conclusion, the community-linkage-based PSA screening model demonstrated high effectiveness in screening for PCa among elderly males in the rural areas of Songjiang, Shanghai City. Epidemiological findings revealed that PCa patients in this region are primarily composed of intermediate and high-risk groups, highlighting the need for intensified early screening and health education.

Objective:To establish a reference interval for serum iodine of pregnant women with normal thyroid function and to analyze the relationship between serum iodine and thyroid disease risk.Methods:From July 2022 to October 2023, using cross-sectional survey method, pregnant women aged 18 to 48 years old who had lived in iodine-deficient areas in the six provinces of China (Shanxi Province, Fujian Province, Yunnan Province, Xinjiang Uygur Autonomous Region, Zhejiang Province, and Anhui Province) for more than six months were selected as the survey subjects. Blood samples were collected, serum iodine was tested, and the percentile method was used to establish a reference interval for serum iodine of pregnant women with normal thyroid function. Meanwhile, serum levels of free thyroxine, thyroid stimulating hormone, thyroglobulin antibody (TgAb), and thyroid peroxidase antibody (TPOAb) were tested, and logistic regression was used to analyze the relationship between serum iodine and thyroid disease risk.Results:A total of 1 409 pregnant women from 6 provinces were investigated, including 1 087 with normal thyroid function and 322 with abnormal thyroid function. The median serum iodine level of pregnant women with normal thyroid function was 79.74 μg/L, and the preliminary reference interval for serum iodine was 47.57 - 128.96 μg/L. When serum iodine levels were lower (< 47.57 μg/L), pregnant women had a significantly increased risk of developing TgAb positivity, TPOAb positivity, hypothyroxinemia, hypothyroidism, and autoimmune thyroiditis ( OR = 4.44, 2.91, 3.41, 41.67, 23.43, P < 0.05). When serum iodine levels were high (> 128.96 μg/L), pregnant women had a significantly increased risk of developing hyperthyroidism ( OR = 9.91, P = 0.001). Conclusions:The reference interval for serum iodine of pregnant women with normal thyroid function is successfully established. Low serum iodine levels are associated with an increased risk of TgAb positivity, TPOAb positivity, hypothyroxinemia, hypothyroidism, and autoimmune thyroiditis, while high serum iodine levels are associated with an increased risk of hyperthyroidism.
