OBJECTIVE:
To review the current research status and hotspots of acupuncture-assisted tumor chemotherapy and provide references for clinical and basic research in this field.
METHODS:
The relevant literature on acupuncture-assisted tumor chemotherapy from the inception of the China National Knowledge Infrastructure (CNKI) and Web of Science (WoS) databases to December 10, 2023, was retrieved. CiteSpace6.2.R4 and VOSviewer1.6.20 software was used to analyze publication volume, authors, institutions, source journals, and keywords, etc. and to create visualized mapping.
RESULTS:
A total of 2 116 articles were included (1 829 from CNKI and 287 from WoS), showing an overall upward trend in publication volume. The scope of acupuncture-assisted tumor chemotherapy has expanded, with a growing variety of research types. In CNKI, the most prolific authors and institutions were from Henan University of CM, forming core research teams. In WoS, the most prolific author was Bao T, and the leading institution was Kyung Hee University in South Korea, although author and institution distribution was more scattered, with close inter-regional collaboration. There were 602 keyword nodes in CNKI and 383 in WoS, with high-frequency keywords in both databases mainly focusing on treatment protocols, cancer types, and chemotherapy-related adverse reactions. CNKI publications highlighted frequent use of acupoints, with more diverse acupoint protocol options, while WoS focused more on different research methods. Recent CNKI studies have focused on improving immune function and quality of life, while "systematic review" emerged as a key term in WoS.
CONCLUSION
Research on acupuncture-assisted tumor chemotherapy should further strengthen collaboration and communication, focus on improving clinical evidence, and promote wider application of acupuncture in integrative oncology research.

The application of medical imaging technology is playing an important role in diagnosis and treatment of cancer.In clinic,the most commonly used imaging technology to detect cancers are X-ray computed tomo graphy,nuclide imaging,magnetic resonance imaging and near-infrared fluorescence imaging.Contrast agents could enhance imaging signals and increase the sensitivity and accuracy of cancer detection.Neverthness,most of clinically used contrast agents have problems such as short retention time and tumor targeting insufficient,which is not favorable to cancer detecting.So it is of great significance to develop tumor targeting contrast agents.Currently,targeting strategies are divided into three types:passive targeting,active targeting and activatable targeting.In this review,we conclude the recent progress and applications of tumor targeting contrast agents of different imaging modilities.Besides,the future development of tumor targeting contrast agents is also prospected.

Objective To investigate the correlation of infiltration of mast cells in kidney with renal interstitial fibrosis, expression of TGF-β1 and stem eel] factor (SCF) in rat models withprotein-overload nephropathy. Methods Sixty uninephrectomized SD rats were randomly divided into model group [intraperitoneal injections of bovine serum albumin (BSA)] and control group (intraperitoneal injections of equal volume of saline). Ten rats from both groups were sacrificed respectively at week 3, 7 and 11 after injection. 24 h urinary protein and serum biochemistry of these SD rats at the time of sacrifice were measured. The intensity of mast cell infiltration was examined by toluidine blue (TB) staining and immunohistochemistry using a monoclonal anti-MC chymase antibody. The expression of TGF-β1 and SCF was detected byimmunohistochemistry, using a monoclonal mouse anti-rat TGF-β1 antibody and a polyclonal rabbstanti-rat SCF antibody. Results Severe proteinuria was induced in the rats by BSA injectionpeaked at week 7 [(199.1±98.4) mg/d] after the BSA injection and gradually decreased until week11 [(133.7±67.8) mg/d]. Renal injury was accompanied with chymase-postitive and TB-postitive mast cell infiltration, in close proximity to areas of interstitial fibrosis. With aggravation oflesions degree, the number of mast cells increased,the difference between the modal rats and control rats was significant (P<0.05). Immunostainahle expression of SCIF and TGF-β1 was detected in tubular as well as interstitial cells, and increased with the BSA injection. The difference between the model rats and control rats was significant (P<0.05). Mast cells were positively correlated with interstitial fibrosis (r=0.772, P<0.01), expression of TGF-β1 (r=0.521, P<0.01) and SCF(r=0.916,P<0.01). Conclusions Increased infiltration of mast cells is involved in interstitial fibrosis of rats with protein-overload nephropathy. Proteinuria may attract mast cells to kidney by chemot actions of SCF,and mast cells may contribute to the development of renal fibrosis by secreting chymase and increasing expression of TGF-β1.
