ObjectiveTo investigate the association between immunoglobulin G (IgG)/immunoglobulin M (IgM) ratio and prognosis in patients with initially unresectable hepatocellular carcinoma (iuHCC) receiving TTP triple therapy with transcatheter arterial chemoembolization (TACE), tyrosine kinase inhibitor (TKI), and programmed cell death protein-1 (PD-1) inhibitors. MethodsA retrospective analysis was performed for the clinical data of 151 iuHCC patients who received TTP triple therapy in Department of Hepatobiliary Surgery, Guangxi Medical University Cancer Hospital, from November 2019 to December 2022, and according to IgG/IgM ratio, they were divided into high IgG/IgM group (IgG/IgM ratio >13.23) and low IgG/IgM group (IgG/IgM ratio ≤13.23). The t-test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. The Kaplan-Meier method and the log-rank test were used for survival analysis, and the Cox proportional hazards model was used to investigate the potential influencing factors for overall survival (OS). ResultsThe 151 patients had a median OS of 26.7 months (95% confidence interval [CI]: 19.8-not reached) and a median progression-free survival of 12.5 months (95%CI: 10.4 — 15.8). The objective response rate was 83.4% and the disease control rate was 94.0%. There were no significant differences in baseline data between the high IgG/IgM group and the low IgG/IgM group (all P>0.05). There was a significant difference in median OS between the high IgG/IgM group and the low IgG/IgM group (20.6 months vs not reached, P=0.016). In both the high IgG/IgM group and the low IgG/IgM group, salvage hepatectomy was significantly associated with the improvement in OS (χ2=8.297 and 10.307, both P<0.05). The multivariate analysis showed that high IgG/IgM ratio (hazard ratio [HR]=1.799, 95%CI: 1.077 — 3.006, P=0.025), baseline alpha-fetoprotein >400 ng/mL (HR=1.762, 95%CI: 1.017 — 3.050, P=0.043), and BCLC stage (HR=2.265, 95%CI: 1.212 — 4.232, P=0.010) were independent influencing factors for OS. ConclusionHigh IgG/IgM ratio is associated with a poorer prognosis in iuHCC patients receiving TTP triple therapy, and salvage hepatectomy has a potential value in improving the prognosis of patients with a high IgG/IGM ratio.

OBJECTIVE To investigate the application and influencing factors of sodium-dependent glucose transporters 2 inhibitors(SGLT-2i) in patients with heart failure with preserved ejection fraction(HFpEF) in the real world. METHODS Data from 358 patients with HFpEF who were hospitalized at the First Affiliated Hospital of Chongqing Medical University from May 2023 to May 2024 were retrospectively collected. The patients were divided into the SGLT-2i group and the non-SGLT-2i group based on whether they were prescribed SGLT-2i upon discharge. Baseline characteristics, comorbidities, and differences in drug treatment were compared between the two groups. Based on univariate analysis, multivariate Logistic regression analysis was performed to identify independent influencing factors of SGLT-2i use in patients with HFpEF, followed by further stratified analysis. RESULTS Among 358 HFpEF patients, the overall utilization rate of SGLT-2i was 33.5%. Combined with type 2 diabetes [OR=9.063,95%CI(4.924-16.679) ] , atrial fibrillation [OR=3.135,95%CI(1.590-6.178) ] , coronary artery heart disease [OR=1.888,95%CI(1.072-3.327) ] and the use of loop diuretics [OR=3.822, 95%CI (1.588-9.200) ] were all independent influencing factors for the use of SGLT-2i in patients with HFpEF ( P <0.05). The results of the stratified descriptive analysis were consistent with those of the multivariate analysis, showing a higher utilization rate of SGLT-2i among patients with concomitant T2DM,atrial fibrillation, coronary artery heart disease, and those receiving loop diuretics ( P <0.05); whereas the utilization rate of SGLT-2i was comparable across patients with different levels of renal function ( P >0.05). CONCLUSIONS In the real-world clinical practice, the utilization of SGLT-2i in patients with HFpEF remains suboptimal, and treatment coverage still needs to be improved. Their use of SGLT-2i is primarily influenced by the presence of type 2 diabetes, atrial fibrillation, coronary artery heart disease, and the use of loop diuretics.

Objective To analyze survival outcomes and influencing factors among patients with colorectal cancer in Yunnan Province. Methods Clinical data were retrospectively collected from 4 892 patients with colorectal cancer. Survival data were obtained through follow-up. Overall survival (OS) was calculated by using the Kaplan-Meier method. Univariate analysis was performed by applying the log-rank test. Meanwhile, multivariate analysis employed the Cox proportional hazards regression model. Results The 1-, 3-, 5-, and 10-year OS rates for the entire cohort were 91.90%, 74.40%, 64.40%, and 28.70%, respectively. Univariate analysis revealed that age, ethnicity, region, differentiation grade, TNM stage, clinical stage, metastatic status, histological type, and treatment modality (chemotherapy, radiotherapy, and surgery) were associated with patient prognosis (all P<0.05). Multivariate analysis identified age (HR=1.250), region (HR=1.262), differentiation grade (HR=0.761), clinical stage (HR=3.128), and treatment modality (chemotherapy, HR=0.644; radiotherapy, HR=1.605; surgery, HR=0.384) as independent factors affecting survival prognosis in patients with colorectal cancer (all P<0.001). Conclusion Age, region, clinical stage, and treatment modality are independent factors influencing survival among patients with colorectal cancer in Yunnan Province. In clinical practice, these factors should be integrated to develop individualized prevention and treatment strategies, thereby improving patient outcomes.

Objective:
To systematically evaluate the therapeutic efficacy and maintenance effects of digital psychological therapies on depressive symptoms among adolescents, so as to provide a reference for clinical practice.
Methods:
Randomized controlled trial(RCT) investigating digital psychological therapies to improve depressive symptoms among adolescents were searched across databases, including PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang database, VIP database, and SinoMed, from database inception to November 20, 2025. Following literature screening, quality assessment, and data extraction, a Meta analysis was performed using Stata 18.0 software.
Results:
A total of 20 studies involving 2 042 adolescents aged 11-19 were included. The Meta analysis revealed that digital psychological therapies significantly alleviated depressive symptoms in adolescents ( SMD =-0.59, 95% CI =-0.85 to -0.32, P <0.01). The therapeutic effect was sustained at long term follow up ( SMD =-0.21, 95% CI =-0.34 to -0.09, P <0.01). Furthermore, depression scores in the intervention group showed a continued decrease from post intervention to long term follow up ( SMD =-0.28, 95% CI =-0.41 to -0.14, P <0.01). Egger s linear regression test indicated possible publication bias (Kendall s tall=0.28, P <0.01).
Conclusions
Digital psychological therapies can effectively improve depressive symptoms among adolescents, with stable long term efficacy. However, current evidence remains limited and exhibits substantial heterogeneity. Therefore, further large sample, high quality RCTs are warranted to validate the effectiveness of this intervention.

ObjectiveTo investigate the association of the traditional Chinese medicine (TCM) syndrome types of primary liver cancer (PLC) with clinical features and multimodal quantitative radiological features on computed tomography (CT) and magnetic resonance imaging (MRI), and to provide a reference for the objectification of TCM syndrome differentiation and precise diagnosis and treatment. MethodsA retrospective analysis was performed for the clinical data of 312 patients who were diagnosed with PLC in The First Affiliated Hospital of Hunan University of Chinese Medicine from March 2020 to June 2025, and according to the TCM syndrome type, they were divided into stagnation of liver Qi group with 40 patients, stagnation of liver Qi and spleen deficiency group with 109 patients, Qi stagnation and blood stasis group with 62 patients, dampness-heat toxin amassment group with 81 patients, and liver-kidney Yin deficiency group with 20 patients. Clinical features and multimodal quantitative radiological features were compared between the patients with different TCM syndrome types. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups; the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups, and the Dunn’s multiple test was used for further comparison between two groups; the chi-square test was used for comparison of categorical data between groups, and the Bonferroni method was used for further comparison between two groups. ResultsThere were significant differences between the patients with different TCM syndrome types in China liver cancer staging (CNLC), Child-Pugh class, alanine aminotransferase, aspartate aminotransferase, albumin, direct bilirubin, total bilirubin, prothrombin time, neutrophil, and albumin-bilirubin score (all P<0.05). In the stagnation of liver Qi group, the patients with Child-Pugh class A accounted for 75.00%; among the patients with CNLC stage I PLC, the patients with stagnation of liver Qi accounted for 60.00%, and those with Qi stagnation and blood stasis syndrome accounted for 59.68%, while among the patients with CNLC stage IV PLC, the distribution proportion of dampness-heat toxin amassment (27.16%) and liver-kidney Yin deficiency (30.00%) was significantly higher than that of stagnation of liver Qi (2.50%) (all P<0.05). Radiological examination showed that there were significant differences between the patients with different TCM syndrome types in the number of tumors, ascites, venous tumor thrombus, maximum tumor diameter, intrahepatic metastasis, and lymph node metastasis in the hepatic hilar and retroperitoneal regions (all P<0.05). Compared with the patients with stagnation of liver Qi, the patients with liver depression and spleen deficiency or liver-kidney Yin deficiency were more likely to develop intrahepatic metastasis; the patients with liver depression and spleen deficiency, dampness-heat toxin amassment, or liver-kidney Yin deficiency were more likely to develop lymph node metastasis in the hepatic hilar and retroperitoneal regions; the patients with liver-kidney Yin deficiency were more likely to experience multiple tumors; the patients with liver depression and spleen deficiency or dampness-heat toxin amassment were more likely to develop ascites (all P<0.05). Compared with the patients with Qi stagnation and blood stasis syndrome, the patients with liver depression and spleen deficiency had a significantly longer maximum tumor diameter and a significantly higher proportion of patients with venous tumor thrombus (both P<0.05). Furthermore, among the 184 patients with MRI diffusion-weighted imaging sequences, the patients with dampness-heat toxin amassment or Qi stagnation and blood stasis syndrome had significantly higher ADC values and relative ADC values than those with stagnation of liver Qi (all P<0.05). ConclusionThere are significant differences in CT/MRI radiological features and clinical features between PLC patients with different TCM syndrome types, among whom the patients with liver depression and spleen deficiency, dampness-heat toxin amassment, and liver-kidney Yin deficiency tend to exhibit progressive radiological features, and those with dampness-heat toxin amassment or Qi stagnation and blood stasis syndrome tend to have higher ADC values. These findings provide an objective basis for TCM syndrome differentiation in PLC.

ObjectiveTo investigate the contamination status of ochratoxin A (OTA) in commercially available food products in Shanghai, and to assess OTA exposure levels and the associated non-carcinogenic and carcinogenic risks among pregnant women by integrating dietary consumption data of this population. MethodsThe levels of OTA contamination in 1 520 food samples collected in Shanghai from 2022 to 2023 were determined using liquid chromatography-tandem mass spectrometry. An exposure assessment model was developed based on the dietary consumption levels of pregnant women from the 2016‒2017 Shanghai Pregnant Women Dietary Monitoring Survey to calculate the estimated daily intake (EDI) of OTA, the margin of exposure for non-carcinogenic toxicity (MOE1), and the margin of exposure for carcinogenic toxicity (MOE2). An MOE1 greater than 200 and an MOE2 greater than 10 000 indicate that the non-carcinogenic toxicity and carcinogenic toxicity resulting from exposure are negligible, respectively. For samples with OTA contamination levels below the limit of detection (LOD), which accounted for more than 80% of the samples, the OTA levels were assigned values of 0 and LOD, respectively, for subsequent calculations. ResultsThe detection rates of OTA in cereals, nuts, dried fruits, and alcohol samples collected in 2022 were 2.03%, 0, 0, and 0, respectively. The OTA detection rates in cereals, nuts, dried fruits, beans, and alcohol samples collected in 2023 were 2.50%, 0.39%, 2.47%, 1.67%, and 13.33%, respectively. For pregnant women in Shanghai in 2022, simulation results indicated that when assigning a value of 0 and the LOD, theP50 values of EDI for dietary OTA exposure were 0.05 and 0.72 ng·(kg·d)-1, respectively, and the P95 values of EDI for dietary OTA exposure were 0.25 and 2.40 ng·(kg·d)-1, respectively. For pregnant women in Shanghai in 2023, the P50 values of EDI for dietary OTA exposure were 0.04 and 1.00 ng·(kg·d)-1, respectively, and the P95 values of EDI for dietary OTA exposure were 0.23 and 2.67 ng·(kg·d)-1, respectively, both substantially below the tolerable daily intake (TDI) for OTA [17 ng·(kg·d)-1]. The EDI for dietary OTA exposure in 100.0% of Shanghai pregnant women was lower than the TDI, indicating an overall low level of dietary OTA exposure among this population. For 100.0% of pregnant women, the MOE₁ for dietary OTA exposure exceeded 200. When assigned a value of 0, the MOE₂ for 100.0% of pregnant women in both 2022 and 2023 exceeded10 000. When assigned the LOD value, 72.3% and 81.8% of pregnant women in 2022 and 2023, respectively, had an MOE₂ exceeding 10 000. ConclusionFrom 2022 to 2023, samples of cereals, nuts, dried fruits, beans, and alcohol sold in Shanghai exhibited varying degrees of OTA contamination. The overall EDI of OTA exposure among pregnant women in Shanghai remained at a low level. The non-carcinogenic and carcinogenic risks associated with OTA exposure were generally low and at controllable levels.

ObjectiveTo investigate the efficacy and safety of simplified diagnosis and treatment strategies and regimens in the treatment of patients with human immunodeficiency virus (HIV)/hepatitis C virus (HCV) co-infection. MethodsThis multicenter prospective real-world study was conducted among 198 patients with HIV/HCV co-infection who received hepatitis C treatment in 10 designated primary hospitals for hepatitis C in Yuxi, China from July 2023 to June 2024, and according to whether genotype detection was performed, they were divided into genotype detection group with 122 patients and non-genotype detection group with 76 patients. The patients were observed in terms of sustained virologic response at 12 weeks (SVR12), safety, and liver biochemical parameters. Propensity score matching was used to match the two cohorts, using caliper matching (caliper value = 0.02) at a ratio of 1∶1. The independent-samples t test or the Wilcoxon signed-rank test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between groups. ResultsAmong the 122 patients in the genotype detection group, 63.11% (77/122) had genotype 3, while the non-genotype detection group had 76 patients; both groups achieved an SVR12 rate of 100%. From baseline to 12 weeks after treatment, both groups had a significant increase in the serum level of albumin, significant reductions in the serum levels of total bilirubin, alanine aminotransferase, aspartate aminotransferase, and alpha-fetoprotein, and a significant reduction in FibroScan value (all P<0.05). A total of 54 patients (27.27%) experienced at least one adverse reaction, and anemia was the most common adverse reaction (38 patients, 19.19%), with an incidence rate of 50.00% (33/66) in patients with liver cirrhosis. HIV viral load remained <50 IU/mL before and after treatment, and there was no significant change in CD4+ T lymphocyte count after treatment (Z=-0.969, P=0.202). Compared with the genotype detection group, the non-genotype detection group had a significantly shorter time from positive HCV RNA testing to treatment initiation (4±2 days vs 19±4 days, t=5.321, P<0.05) and significantly lower testing costs (618±97 yuan vs 789±129 yuan, t=3.661, P<0.05). ConclusionFor patients with HIV/HCV co-infection, the simplified diagnosis and treatment strategies can achieve a relatively high SVR12 rate, improve biochemical indicators, and effectively reduce time cost and economic burden, with a favorable safety profile.

Objective: To analyze the characteristics and key risk factors of abnormal blood disposal throughout the 2024-2025 blood collection and supply process based on nationwide multi-site monitoring data, develop a comprehensive prevention and control strategy across the entire chain, reduce preventable blood waste, and ensure clinical blood safety. Methods: According to the Guidelines for Haemovigilance (T/CSBT 001-2026), we extracted 74 cases of abnormal blood disposal events reported by the China Blood Transfusion Association′s Blood Safety Monitoring System from January 1 2024, to December 31 2025, and conducted descriptive statistical analysis on the distribution of events, types of deviations, root causes, and classifications of disposal manifestations. Results: A total of 664 adverse events related to blood collection and supply were reported over two years, with 74 cases involving discarded abnormal blood units, accounting for 11.1% of the total. Among these, blood component preparation (40.5%) and blood collection (37.8%) remained traditional high-risk stages. The proportion of blood waste occurring during storage, distribution, and transportation increased from 7.7% in 2024 to 34.3% in 2025. Deviations from standard operating procedures (SOP) by personnel were the primary cause, accounting for 74.3% of cases. Discarded blood units were categorized into four types: compromised closed blood bag systems (40 cases), mainly due to inadequate heat sealing, physical damage, or dropped bags; blood out of the cold chain (12 cases), primarily resulting from blood being left at work sites; imbalanced proportion of preservation solution (10 cases), mostly caused by blood collection volumes exceeding the standard capacity of blood bags; and other causes (12 cases). Conclusion: Human operational errors are the core cause of abnormal blood waste. The collection and preparation stages have long been at high-risk, and the risks in the storage and transportation stages have been increasing year by year. We should focus on standardizing personnel management, improving specialized operation norms such as heat sealing, transportation, and storage, establishing a full-process intelligent cold chain monitoring and multi-node visual verification mechanism, and systematically reducing the occurrence rate of abnormal blood waste through a closed-loop quality intervention system, thereby improving the utilization efficiency of voluntary blood donation resources.

ObjectiveTo investigate the value of preoperative dual-layer spectral detector CT (DLCT) parameters in predicting lymph node metastasis (LNM) of non-functional pancreatic neuroendocrine neoplasms (NF-pNENs). MethodsA retrospective study was conducted on patients with pathologically confirmed NF-pNENs who underwent preoperative contrast-enhanced DLCT examination between September 2019 and July 2024. Regions of interest (ROIs) were manually delineated on three representative slices of the solid component of the lesion, and the mean values were recorded. Conventional CT parameters, monochromatic energy images (40 keV, 70 keV, 100 keV), iodine concentration maps, and effective atomic number (Zeff) maps in the pancreatic parenchymal phase and portal venous phase were acquired. A total of 34 parameters, including clinical characteristics, imaging features, conventional CT and DLCT quantitative parameters, were analyzed. Intergroup differences were compared between the LNM and non-LNM groups. Independent predictive factors were screened using logistic regression and least absolute shrinkage and selection operator (LASSO) regression. Receiver operating characteristic (ROC) curves were generated for each predictive model, and the area under the curve (AUC) was calculated to evaluate the predictive efficacy. ResultsA total of 82 patients with NF-pNENs were enrolled, including 37 males and 45 females, with a mean age of 49.7±14.7 years. Thirty patients were performed with LNM and 52 were with non-LNM. After univariate logistic regression, LASSO regression and multivariate stepwise logistic regression analyses, body mass index (BMI), organ invasion, normalized CT value in the portal venous phase (nCTv) and normalized iodine concentration in the portal venous phase (nICv) were identified as independent predictive factors. The AUCs of the clinical-radiological qualitative model (BMI+organ invasion), conventional CT model (nCTv), DLCT model (nICv) and comprehensive model (organ invasion+nICv) were 0.815 (0.719, 0.910), 0.750 (0.642, 0.858), 0.829 (0.733, 0.925) and 0.865 (0.879, 0.953), respectively. The comprehensive model combining clinical-radiological and DLCT characteristics exhibited superior predictive performance. ConclusionDLCT parameters are more effective than conventional CT parameters in predicting LNM in NF-pNENs, enabling non-invasive preoperative prediction and assisting clinical decision-making.
