ObjectiveTo study the efficacy of transcatheter arterial chemoembolization (TACE) combined with surgical resection in the treatment of ruptured hepatocellular carcinoma (HCC).MethodsThe clinical data of 26 patients who presented with ruptured HCC to our hospital from January 2008 to December 2011 were retrospectively studied. These patients received TACE (n=19),surgical resection (n=7),and surgical resection after TACE (n=8).ResultsShock in the 19 patients who received TACE was promptly corrected and the vital signs were stabilized.On subsequent CT,the tumors shrunk in size.Salvage liver resection was carried out in 8 patients 1 month after TACE.After treatment,AFP decreased or became normalized,thus the treatment results were good. A one-stage liver resection was carried out in 7 patients. One patient died after operation and peritoneal metastases occurred in 4 patients. Conclusions TACE stopped bleeding from ruptured HCC efficaciously,reduced the need for open exploration,and improved the rate of resection of HCC.TACE combined with surgical resection significantly lowered the rate of abdominal tumor metastases.

AIM: To identify the down-regulated genes in adult rat cardiac fibroblasts (CF) stimulated with angiotensin Ⅱ (AngⅡ). METHODS: Suppression subtractive hybridization (SSH) was performed between the CF stimulated by AngⅡ (driver) and unstimulated CF (tester) to generate subtractive cDNA library. The library was screened with dot blots hybridization to further verify the differentially expressed cDNA clones. Partial positive clones were sequenced and BLAST analyzed. RESULTS: Seventeen down-regulated genes related to intracellular signal transduction, transcriptional repression, deposition of fibrous matrix and cellular cytoskeletal rearrangement, and 4 new expression sequence tags (EST) were acquired. CONCLUSION: SSH is a powerful technique with high sensitivity for the detection and clone of down-regulated genes expressed in CF induced by AngⅡ, which is helpful to clarify the mechanism of cardiac remodeling.

As people’s attention to health continues to increase, the market demand for traditional Chinese medicine (TCM) is growing steadily. The quality and safety of Chinese medicinal materials have attracted unprecedented social attention. In particular, the issue of exogenous harmful residue pollution in TCM has become a hot topic of concern for both regulatory authorities and society. The Chinese Pharmacopoeia 2025 Edition further refines the detection methods and limit standards for exogenous harmful residues in TCM. This not only reflects China’s high-level emphasis on the quality and safety of TCM but also demonstrates the continuous progress made by China in the field of TCM safety supervision. Basis on this study, by systematically reviewing the development history of the detection standards for exogenous harmful residues in TCM and analyzing the revisions and updates of these detection standards in the Chinese Pharmacopoeia 2025 Edition, deeply explores the key points of the changes in the monitoring standards for exogenous harmful residues in TCM in the Chinese Pharmacopoeia 2025 Edition. Moreover, it interprets the future development directions of the detection of exogenous residues in TCM, aiming to provide a reference for the formulation of TCM safety supervision policies.
