ObjectiveTo investigate the inhibitory effect of Biejiajian Pills （BJJW） on the growth of liver cancer， as well as its potential mechanism in mediating the AMP-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR） pathway through mitochondrial energy metabolism. MethodsHuman hepatoma Huh7 cells were used to establish a nude mouse model of subcutaneous xenograft tumor. A total of 18 tumor-bearing nude mice were randomly divided into model group， BJJW group （2.2 g/kg）， and metformin group （250 mg/kg）， and the corresponding drug was given by gavage for 14 consecutive days. Tumor volume and weight were monitored during the experiment； HE staining was used to observe histopathological changes； the levels of reactive oxygen species （ROS） and adenosine triphosphate （ATP） in tumor tissue were measured； immunohistochemistry and Western blotting were used to measure the expression levels of proteins associated with the AMPK/mTOR pathway. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups， and the Tukey’s 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 test was used for further comparison between two groups. ResultsCompared with the model group， the BJJW group had a tumor inhibition rate of 45.73%， with significant reductions in both tumor volume and weight （P<0.01）. Pathological examination showed that compared with the model group， the BJJW group had a significant reduction in the number of tumor cells and the presence of extensive necrosis. Mechanistic studies showed that compared with the model group， the BJJW group had a significant increase in ROS level （P<0.001） and a significant reduction in ATP level （P<0.001）， as well as significant increases in p-AMPK/AMPK ratio （0.81±0.20 vs 0.13±0.04， P<0.01） and p-ULK1/ULK1 ratio （0.69±0.17 vs 0.18±0.13， P<0.01） and a significant reduction in p-mTOR/mTOR ratio （1.34±0.16 vs 3.20±0.62， P<0.01）. ConclusionBJJW may inhibit the growth of liver cancer by inducing mitochondrial energy metabolism dysfunction， increasing the level of ROS， reducing the level of ATP， and activating the AMPK/mTOR signaling pathway.

Objective: To evaluate the causal effects and population heterogeneity of Guangzhou′s Voluntary Blood Donation Privilege Certificate Policy on blood donation behavior, and to provide empirical evidence for optimizing blood management policies. Methods: Using an interrupted time series (ITS) design, we analyzed 30 quarters of blood collection data from Guangzhou Blood Center (from July 2018 to December 2025). Taking the third quarter of 2021 as the intervention node, we constructed ordinary least squares (OLS) regression models incorporating level and trend effects, and conducted stratified analyses by gender, age group, previous donation frequency, and per-donation volume. Results: The tiered incentive policy demonstrated significant heterogeneous effects. Apheresis donations showed sustained growth, with 2 units of component blood exhibiting a significant trend effect (β=304.58, P<0.001); high-frequency donors (11+ times) demonstrated sustained growth trends in apheresis donations. For whole blood, immediate effects were significant for donors with 1-2 previous donations (β=4 537.55, P<0.001) and 3-10 previous donations (β=2 159.69, P<0.05); high-frequency donors (11-30 times) showed sustained growth trends (P<0.01). Stratified by per-donation volume, 400 mL whole blood demonstrated a significant immediate effect (β=4 391.01, P<0.1), while 200 mL whole blood showed a significant declining trend (β=-893.24, P<0.01). Conclusion: The tiered incentive policy effectively enhanced blood donation participation while maintaining the donors’ altruistic motivations. Young and middle-aged adults primarily drove apheresis donations. The policy demonstrated immediate incentive effects on low-frequency whole blood donors and long-term retention effects on high-frequency donors. Per-donation volume showed an "upward migration" trend, optimizing the blood collection structure. Differentiated outreach, conversion and retention strategies are recommended to further strengthen blood supply security.

On July 1， 2026， Hepatology International published online the APASL clinical practice guidance on the diagnosis and management of patients with Wilson’s disease. The guidance formulates 22 recommendations for Wilson’s disease from the aspects of clinical manifestations， laboratory and imaging diagnostics， genetic testing， family screening， lifestyle modifications， pharmacotherapy， liver transplantation， pregnancy management， and care for asymptomatic/presymptomatic patients. This article systematically reviews the core contents of this guidance， with a particular focus on the excerpted recommendations for diagnosis and treatment， in order to provide a practical reference for the clinical identification， diagnosis， and long-term management of patients with Wilson’s disease.

Hereditary hemochromatosis （HH） is a hereditary disease characterized by iron overload resulting from mutations in genes involved in iron metabolism. Type ⅣA HH， also known as classical ferroportin disease， is caused by loss-of-function mutations in the SLC40A1 gene and has the clinical manifestations of a significant increase in serum ferritin， normal or low transferrin saturation， and marked iron deposition in the spleen. This article reports a case of type ⅣA HH with a significant asymptomatic increase in serum ferritin. Magnetic resonance imaging showed that the severity of iron overload in the spleen was significantly higher than that in the liver； liver biopsy showed mild fatty liver disease and iron deposition in Kupffer cells； gene variation analysis identified a heterozygous mutation in SLC40A1 c.485_487del （p.Val162del）. Screening of family members showed that the proband’s mother carried the same variation and had the manifestation of iron overload in the liver and spleen， which further confirmed the pathogenicity of this variation. This case highlights that type ⅣA HH often has an insidious onset and is frequently misdiagnosed. For patients with an unexplained persistent increase in serum ferritin， active genetic testing for HH should be considered， even in the presence of concurrent liver diseases， in order to realize early diagnosis and intervention.

Purpose: This study assessed the performance of the ultrasound-guided attenuation parameter (UGAP) in diagnosing and grading hepatic steatosis in patients with metabolic dysfunctionassociated steatotic liver disease (MASLD). Magnetic resonance imaging proton density fat fraction (MRI-PDFF) served as the reference standard. Methods: Patients with hepatic steatosis were enrolled in this prospective study and underwent UGAP measurements. MRI-PDFF values of ≥5%, ≥15%, and ≥25% were used as references for the diagnosis of steatosis grades ≥S1, ≥S2, and S3, respectively. Spearman correlation coefficients and area under the receiver operating characteristic curves (AUCs) were calculated. Results: Between July 2023 and June 2024, the study included 88 patients (median age, 40 years; interquartile range [IQR], 36 to 46 years), of whom 54.5% (48/88) were men and 45.5% (40/88) were women. Steatosis grades exhibited the following distribution: 22.7% (20/88) had S0, 50.0% (44/88) had S1, 21.6% (19/88) had S2, and 5.7% (5/88) had S3. The success rate for UGAP measurements was 100%. The median UGAP value was 0.74 dB/cm/MHz (IQR, 0.65 to 0.82 dB/ cm/MHz), and UGAP values were positively correlated with MRI-PDFF (r=0.77, P<0.001). The AUCs of UGAP for the diagnoses of ≥S1, ≥S2, and S3 steatosis were 0.91, 0.90, and 0.88, respectively. In the subgroup analysis, 98.4% (60/61) of patients had valid controlled attenuation parameter (CAP) values. UGAP measurements were positively correlated with CAP values (r=0.65, P<0.001). Conclusion Using MRI-PDFF as the reference standard, UGAP demonstrates good diagnostic performance in the detection and grading of hepatic steatosis in patients with MASLD.

Inflammatory diseases (IDs) are a general term of diseases characterized by chronic inflammation as the primary pathogenetic mechanism, which seriously affect the quality of patient′s life and cause significant social and medical burden. Current drugs for IDs include nonsteroidal anti-inflammatory drugs, corticosteroids, immunomodulators, biologics, and antioxidants, but these drugs may cause gastrointestinal side effects, induce or worsen infections, and cause non-response or intolerance. Given the outstanding performance of metal polyphenol network (MPN) in the fields of drug delivery, biomedical imaging, and catalytic therapy, its application in the diagnosis and treatment of IDs has attracted much attention and significant progress has been made. In this paper, we first provide an overview of the types of IDs and their generating mechanisms, then sort out and summarize the different forms of MPN in recent years, and finally discuss in detail the characteristics of MPN and their latest research progress in the diagnosis and treatment of IDs. This research may provide useful references for scientific research and clinical practice in the related fields.

Objective:To explore the role of long noncoding RNA(lncRNA) CCDC18-AS1 in parathyroid carcinoma(PC) diagnosis.Methods:This cross-sectional study included 55 patients with primary hyperparathyroidism treated at Beijing Shijitan Hospital from 2013 to 2024. Of these, 12 patients were diagnosed with PC and 43 with parathyroid adenoma(PA). Tissue samples and clinical data were collected, and lncRNA CCDC18-AS1 expression were measured using real-time quantitative PCR(RT-qPCR).Results:LncRNA CCDC18-AS1 expression was significantly higher in the PC group than that in the PA group( P=0.003). It was identified as an independent risk factor for PC, independent of age, sex, or serum calcium levels. Among patients with hypophosphatemia, no significant differences in lncRNA CCDC18-AS1 expression was observed between the PC and PA groups. However, in patients with normal serum phosphate levels, lncRNA CCDC18-AS1 expression was significantly higher in the PC group( P<0.001) and showed a positive correlation with serum phosphorus concentration( P=0.001). The area under the receiver operating characteristic(ROC) curve(AUC) for lncRNA CCDC18-AS1 in PC diagnosis was 0.758(95% CI 0.620-0.866, P=0.005), comparable to that of lncRNA plasmacytoma variant translocation 1(PVT1). Among patients with normal serum phosphate, the AUC for lncRNA CCDC18-AS1 increased to 0.969(95% CI 0.835-0.999, P<0.001), with 100% sensitivity and 92.31% specificity, suggesting superior diagnostic performance compared to PVT1(0.840, 95% CI 0.653-0.950, P=0.001). Conclusions:LncRNA CCDC18-AS1 may serves as a potential biomarker for PC diagnosis, with greater diagnostic value in patients with normal serum phosphorus levels.

Objective:To investigate the efficacy and safety of high-frequency irreversible electroporation (H-FIRE) in treating benign prostatic hyperplasia (BPH).Methods:This randomized controlled open-label multicenter clinical trial enrolled patients from nine medical centers in China between August 2020 and July 2022. Inclusion criteria: age 50–80 years, International Prostate Symptom Score (IPSS) ≥12, maximum urinary flow rate (Q max) >5 ml/min and ≤15 ml/min. Exclusion criteria: prostate malignancy, contraindications to surgery or anesthesia. Patients were randomized 1∶1 into the H-FIRE group (experimental) or the control group (daily oral 0.2 mg tamsulosin hydrochloride sustained-release capsules). Primary outcomes included Q max, IPSS, prostate volume, and International Index of Erectile Function-5 (IIEF-5) scores, measured at baseline, 1 and 3 months post-treatment. Results:A total of 160 cases were included in this study, including 80 cases in the experimental group and 80 cases in the control group, 30 cases in Renji Hospital, 7 cases in Qilu Hospital of Shandong University, 8 cases in Tongji Hospital, 3 cases in Hunan Provincial Hospital, 13 cases in Shanghai Pudong Hospital, 29 cases in Hwa Mei Hospital, 18 cases in Yiyuan County People's Hospital, and 38 cases in Shanghai East Hospital, and 14 cases in Sun Yat-sen Memorial Hospital. At 3 months of post-treatment, Q max in the experimental group increased by a median of 7.50 (3.55, 14.50) ml/s from the baseline value, whereas in the control group it increased by a median of 1.70 (-1.40, 6.00) ml/s, and the difference between the two groups was statistically significant ( P < 0.01, U = 1 083); and at 3 months of post-treatment, IPSS in the experimental group decreased by a median of 12.00 (7.00, 17.00) points in the test group and 6.00 (2.00, 11.00) points in the control group, and the magnitude of improvement in IPSS scores in the test group was significantly higher than that in the control group ( P < 0.01, U = 1 248); at 3 months of post-treatment, the prostate volume decreased by a median of 12.16 (5.69, 18.27) ml in the experimental group and 0 (-3.94, 6.89) ml in the control group, suggesting that H-FIRE significantly reduced prostate gland volume ( P<0.01, U=1 111). The difference in elevated IIEF-5 scores from baseline at 3 months of treatment between the experimental and control groups was not statistically significant[0(-2.00, 1.00) points vs. 0(-2.00, 1.50) points; P=0.54, U=2 338]. There were no serious adverse events in the two groups. Conclusions:H-FIRE could significantly improve both subjective and objective symptoms of BPH with a low risk of severe complications.

Objective:To explore the curative effect of abdominal flap carried with combined perforating vessels in reconstruction of extra large and complicated defect in extremities.Methods:A retrospective analysis was conducted on 16 patients who were admitted to the Department of Hand Surgery, the Affiliated Traditional Chinese Medicine Hospital for treatment of extra large and complex wounds in extremities, from January 2020 to December 2023. There were 6 defects in upper limbs and 10 in lower limbs. Fourteen patients had a combination of fracture and 6 of tendon defects. The defects were large and sized from 30.0 cm×9.0 cm to 35.0 cm×15.0 cm. The defects were reconstructed by large sized abdominal flaps at 32.0 cm×10.0 cm to 36.0 cm×16.0 cm. According to the size of the defect, perforators of different arteries carried by the abdominal flap were combined by anastomosis in a manner of internal and external supercharging in order to boost the blood supply of the flap. The supercharging vessel anastomosis was as follows: one superficial circumflex iliac artery (or superficial inferior epigastric artery) was anastomosed with the contralateral branch of the deep inferior epigastric artery, with the veins were anastomosed with the corresponding veins, and the main trunk of the deep inferior epigastric artery was anastomosed end-to-end or end-to-side with the main branch of the recipient artery. Alternatively, both of the left and right superficial iliac circumflex (or inferior epigastric) arteries were directly anastomosed end-to-side or end-to-end with the main trunk or its branches in the recipient site, and the veins were anastomosed end-to-side or end-to-end with the adjacent veins. The donor site was pulled and relaxed by a pull-rod wound expander and sutured layer by layer. After surgery, routine anti-infection, anti-vasospasm, anticoagulation, enhancement of blood circulation and other symptomatic treatment were given. Postoperative follow-ups were conducted at outpatient clinic and via telephone and WeChat interviews. The colour and the sign of capillary reflux of the flap were closely observed.Results:All patients were included in the postoperative follow-up for 6-26 months, with an average of 13 months. Fifteen flaps survived after surgery. One flap had partial necrosis and the necrosis was found being caused by a thrombosis at the vessel anastomotic site. The necrotic tissue was removed and the defect was reconstructed by a flap transfer. The abdominal donor sites healed by first intention, and the navel was normal in terms of location and shape. There was no muscle hernia, except a minor scar hyperplasia. The flaps healed well, with satisfactory appearance and soft texture, without obvious bloating. The donor site healed well with partial scar formation.Conclusion:When an abdominal flap is used to reconstruct an extremely large and complex defect in extremities, the perforating vessels of different source arteries carried by the flaps can be anastomosed in a manner of combination, hence the flap can be flexibly freed, with satisfactory treatment effects.

AIM To observe the effects of Hugan Tablets on high-fat diet induced non-alcoholic fatty liver disease(NAFLD)in a mouse model,and the autophagy,pyroptosis and the PI3K/Akt/mTOR signaling pathway as well.METHODS The C57BL/6 mice were randomly divided into the normal group,the model group,the Hugan Tablets group(0.7 g/kg)and the Yishanfu group(0.23 g/kg),with 10 mice in each group.The NAFLD mouse model was established by 16 weeks feeding of high-fat diet.From the 13th week,the mice started their corresponding dosing of the drug by gavage followed by killing of the mice at the end of 16th week and collection of their serum and liver tissue samples.The mice had their serum ALT,AST,TG,TC,LDL levels,liver TG,TC,NEFA,MDA levels and activities of SOD and GSH-Px detected;their serum levels of IL-1β,IL-6 and TNF-αdetected by ELISA;their hepatic pathological changes observed using HE staining and oil red O staining;and their hepatic protein expressions of ACC,CPT1A,FAS,p-PI3K,p-Akt,p-mTOR,P62,LC3,NLRP3,GSDMD and Caspase1 detected by Western blot.RESULTS Compared with the model group,the Hugan Tablets group displayed decreased body weight and hepatosmatic index level(P＜0.01);decreased levels of serum ALT,AST,TG,TC,LDL,IL-6,IL-1β and TNF-α(P＜0.05,P＜0.01);increased hepatic levels of TG,TC,NEFA and MDA(P＜0.05);decreased activities of SOD and GSH-Px(P＜0.05);improved pathological changes of hepatic lipid deposition and hepatocytic ballooning and decreased NAS score and oil red O staining area(P＜0.01);decreased hepatic protein expressions of ACC1,FAS,NLRP3,Caspase1,GSDMD,P62,p-PI3K,p-Akt and p-mTOR(P＜0.05,P＜0.01);and increased protein expressions of CPT1A and LC3(P＜0.01).CONCLUSION Hugan Tablets can effectively prevent and control the development of high-fat diet induced NAFLD in mice,and the mechanism may be associated with the promotion of autophagy in hepatocytes and the inhibition of pyroptosis via the inhibition of PI3K/Akt/mTOR signaling pathway.
