Following the publication of this paper, it was drawn to the Editor's attention by a concerned reader that, regarding the cell invasion assay data shown in Fig. 4A, the 'Control' and 'pU‑siNC' data panels appeared to share an overlapping section of data, such that data which were intended to show the results of differently performed experiments had apparently been derived from the same original source. The authors were contacted by the Editorial Office to offer an explanation for this apparent anomaly in the presentation of the data in this paper; however, up to this time, no response from them has been forthcoming. Owing to the fact that the Editorial Office has been made aware of potential issues surrounding the scientific integrity of this paper, we are issuing an Expression of Concern to notify readers of this potential problem while the Editorial Office continues to investigate this matter further.

This study aimed to explore the bidirectional causal relationship between inflammatory bowel disease (IBD) and Hashimoto thyroiditis (HT) using Mendelian randomization (MR) analysis. While both conditions are characterized by persistent inflammation and immune dysregulation, the direction of causality remains unclear. We performed a 2-sample bidirectional MR analysis using summary statistics from genome-wide association studies for IBD and HT. Genetic variants strongly associated with IBD and HT were selected as instrumental variables for forward and reverse MR analyses, respectively. Various MR methods, including inverse-variance weighted (IVW), MR-Egger regression, weighted median, and weighted mode, were employed to assess causal relationships. Sensitivity analyses were conducted to evaluate the reliability of results, including tests for pleiotropy and heterogeneity. Data were sourced from individuals of European descent to minimize population stratification bias. In the forward MR analysis, no strong evidence of a causal effect of IBD on HT was found, with the IVW method yielding an odds ratio (OR) of 0.9617 (95% CI: 0.7549-1.2251; P = .7519) Similarly, in the reverse MR analysis, no significant causal effect of HT on IBD was observed, with the IVW method showing an OR of 0.9991 (95% CI: 0.9693-1.0298, P = .9527). Sensitivity analyses confirmed the absence of heterogeneity or pleiotropic effects that could influence the results. The MR-PRESSO analysis did not detect any outlier SNPs. This bidirectional MR analysis provides no evidence for a causal relationship between IBD and HT in either direction.
Hepatocellular carcinoma (HCC) is one of the deadliest malignancies worldwide featured with the poor prognosis and high mortality in affected patients. Given its insensitivity to conventional systemic chemotherapy, the development of novel modalities for HCC management is highly urgent. Sonodynamic therapy (SDT) has gained considerable momentum in cancer therapy. Especially, through synergistic SDT/chemotherapy, SDT would enhance the chemotherapeutic process on inhibiting tumor growth, which holds great potential on combating HCC. In this work, we report on the design/fabrication of targeted biodegradable nanosonosensitizers based on hollow mesoporous organosilica nanoparticles (HMONs), followed by pore-engineering including covalent anchoring of protoporphyrin (PpIX, HMONs-PpIX) and conjugation of arginine-glycine-aspartic acid in order to specifically targeting HCC cells. Such nanosonosensitizers provide efficient loading and controllable stimuli-responsive release of chemotherapeutic agents for HCC-targeting chemotherapy, thus promoting an enhancing chemotherapeutic process via the unique sonotoxicity under ultrasound irradiation. The HMONs matrix with biologically active organic groups in the framework (disulfide bond) are endowed with intrinsic tumor microenvironment-responsive biodegradability and improved biocompatibility/biosafety. In particular, a synergistic inhibition effect of drug-loaded HMONs-PpIX-arginine-glycine-aspartic acid on HCC growth has been systematically demonstrated both in vitro and in vivo (84.7% inhibition rate), which brings insights and meets the versatile therapeutic requirements for HCC management.

Objectives: A potentially curative hepatic resection is the optimal treatment for hepatocellular carcinoma (HCC), but most HCCs, even at an early stage, eventually recur after resection. To investigate clinical features of initial recurrence and long-term prognosis of patients after recurrence. Methods: From a multicenter database, patients withearly-stage HCC (Barcelona Clinic Liver Cancer [BCLC] stage 0/A) were retracted. Time to initial recurrence, patterns of recurrence, and treatment modalities for recurrent tumors were investigated. Univariable and multivariable analysis were used to identify independent risks associated with postoperative recurrence, as well as post-recurrence survival (PRS). Results: Among 1,424 patients, 679 (47.7%) developed recurrence at a median follow-up of 52.9 months, including 412 (60.7%) early recurrence (≤2 years after surgery) and 271 (31.3%) late recurrence (>2 years). Independent risks of postoperative recurrence included cirrhosis, preoperative alpha-fetoprotein level>400ug/L, tumor size>5cm, multiple tumors, satellites, microvascular invasion, and intraoperative blood transfusion. The most common pattern for initial recurrence were intrahepatic only (87.3%), while the median PRS of patients with recurrence was 22.4 months. Multivariable analysis revealed that receiving irregular recurrence surveillance, beyond Milan criteria of the initial tumor, early recurrence, BCLC stage B/C of the recurrent tumor, and non-curative treatments were independently associated with poorer PRS. Conclusions: Nearly half of patients with early-stage HCC experienced recurrence after resection. Understanding recurrence risks may help identify patients at high risk of recurrence who may benefit from future adjuvant therapies. Meaningful survival even after recurrence can still be achieved by postoperative regular surveillance and curative treatment.
Background: Hepatocellular carcinoma (HCC) is one of the most common malignancies in China. Most HCC patients are first diagnosed at an advanced stage, and systemic treatments are the mainstay of treatment. Summary: In recent years, immune checkpoint inhibitors have made a breakthrough in the systemic treatment of middle-advanced HCC, breaking the single therapeutic pattern of molecular-targeted agents. To better guide the clinical treatment for effective and safe use of immunotherapeutic drugs, the Chinese Association of Liver Cancer and Chinese Medical Doctor Association has gathered multidisciplinary experts and scholars in relevant fields to formulate the “Chinese Clinical Expert Consensus on Immunotherapy for Hepatocellular Carcinoma (2021)” based on current clinical studies and clinical medication experience for reference in China. Key Messages: The consensus contained 17 recommendations, including the preferred regimen for first- and second-line immunotherapy, evaluation and monitoring before/during/after treatment, management of complications, precautions for special patients, and potential population for immunotherapy.
Non-alcoholic fatty liver disease (NAFLD) is emerging as an epidemic risk factor for hepatocellular carcinoma (HCC). The progression of NAFLD to HCC is closely associated with paracrine communication among hepatic cells. Vascular endothelial growth factor A (VEGFA) plays a key role in NAFLD and HCC; however, the cellular communication of VEGFA in the pathological transition from NAFLD to HCC remains unclear. Here, we found that VEGFA elevation was considerably distributed in hepatocytes of clinical and murine NAFLD-HCC specimens. Notably, progression from NAFLD to HCC was attenuated in hepatocyte-specific deletion of Vegfa (VegfaΔhep) mice. Mechanistically, VEGFA activated human hepatic stellate cell (HSC) LX2 into a fibrogenic phenotype via VEGF-VEGFR signaling in fatty acid medium, and HSC activation was largely attenuated in VegfaΔhep mice during NAFLD-HCC progression. Additionally, a positive correlation between VEGFA and hepatic fibrosis was observed in the NAFLD-HCC cohort, but not in the HBV-HCC cohort. Moreover, LX2 cells could be activated by conditioned medium from NAFLD-derived organoids, but not from HBV livers, whereas this activation was blocked by a VEGFA antibody. In summary, our findings reveal that hepatocyte-derived VEGFA contributes to NAFLD-HCC development by activating HSCs and highlight the potential of precisely targeting hepatocytic VEGFA as a promising therapeutic strategy for NAFLD-HCC.
Background: Surgical resection is the only treatment modality that ensures complete tumor removal in patients with liver tumors involving a major hepatic vein. Central hepatectomy is a challenging procedure that often result in large defect at the right hepatic vein, which is not amenable to suturing or end-to-end anastomosis. Meanwhile, good outflow reconstruction is essential for early postoperative recovery and long-term survival. Methods: We describe a simple technique for reconstructing the right hepatic vein. The technique is an effective method for reconstructing large venous defects after the hepatic vein resection. Reconstruction of the right hepatic vein has the advantages of prevention of congestion in segments VI and VII. Conclusions: This technique allows surgeons to reconstruct the hepatic vein without synthetic vascular grafts and cryopreserved veins.
Portal vein tumor thrombus (PVTT) is very common and it plays a major role in the prognosis and clinical staging of hepatocellular carcinoma (HCC). We have published the first version of the guideline in 2016 and revised in 2018. Over the past several years, many new evidences for the treatment of PVTT become available, especially for the advent of new targeted drugs and immune checkpoint inhibitors which have further improved the prognosis of PVTT. So, the Chinese Association of Liver Cancer and Chinese Medical Doctor Association revised the 2018 version of the guideline to adapt to the development of PVTT treatment. Future treatment strategies for HCC with PVTT in China would depend on new evidences from more future clinical trials.
