Current status and trend of acupuncture-moxibustion for myofascial pain syndrome: a visual analysis of knowledge graph based on CiteSpace and VOSviewer / 中国针灸

Bibliometric and scientific knowledge graph methods were used to analyze the research status and hot spots of acupuncture-moxibustion in treatment of myofascial pain syndrome (MPS) and explore its development trend. The articles of both Chinese and English versions relevant to MPS treated by acupuncture-moxibustion were searched in CNKI, VIP, Wanfang, SinoMed and WOS from the database inception to March 20, 2023. Using Excel2016, CiteSpace6.2.R2 and VOSviewer1.6.18, the visual analysis was conducted by means of the cooperative network, keyword co-occurrence, keyword timeline, keyword emergence, etc. From Chinese databases and WOS database, 910 Chinese articles and 300 English articles were included, respectively. The annual publication volume showed an overall rising trend. Literature output of English articles was concentrated in Spain, China, and the United States, of which, there was less cross-regional cooperation. In the keyword analysis, regarding acupuncture-moxibustion therapy, Chinese articles focused on "acupuncture", "electroacupuncture" and "acupotomy"; while, "dry needling" and "injection" were dominated for English one. Clinical study was the current hot spot in Chinese databases, in comparison, the randomized controlled double-blind clinical trial was predominant in WOS. Both Chinese and English articles were limited in the report of mechanism research. The cooperation among research teams should be strengthened to conduct comparative research, dose-effect research and effect mechanism research with different methods of acupuncture-moxibustion involved so that the evidences can be provided for deeper exploration.

Construction and identification of the adenoviral vector with dual reporter gene for multimodality molecular imaging / 华中科技大学学报（医学）（英德文版）

In this study, the recombinant adenovirus (Ad) vector containing dual reporter gene [i.e. human transferrin receptor gene (TFRC) and firefly luciferase reporter gene] was constructed to provide a novel experimental tool for magnetic resonance (MR) and bioluminescence dual-modality molecular imaging. The cDNA of TFRC was amplified by polymerase chain reaction (PCR) and cloned into the multiple cloning site of pShuttle-CMV-CMV-Luciferase vector. After identification by Sfi I digestion and sequencing, pShuttle-TFRC-Luciferase vector and the adenoviral backbone vector (pAdeno) were subjected to homologous recombination. The correct recombinant plasmid was then transfected into 293 packaging cells to produce adenoviral particles and confirmed by PCR. After infection of human colorectal cancer LOVO cells with Ad-TFRC-Luciferase, the expressions of transferrin receptor (TfR) and luciferase protein were detected respectively by Western blotting and bioluminescence imaging in vitro. The results showed that TFRC gene was successfully inserted into the adenoviral shuttle vector carrying luciferase gene. DNA sequence analysis indicated that the TFRC gene sequence in the shuttle plasmid was exactly the same as that reported in GenBank. The recombinant plasmid was identified correct by restriction digestion. Ad-TFRC-Luciferase recombinant adenovirus was constructed successfully, and the virus titer was 1.6×10(10) pfu/mL. Forty-eight h after dual reporter gene transfection, the expressions of TfR and luciferase protein were increased significantly (P<0.01). It was concluded that the recombinant adenovirus vector with dual reporter gene was successfully established, which may be used for in vivo tracing target cells in multimodality imaging.

Expression and significance of p53-inducible gene 3 (PIG-3) in diffuse large B cell lymphoma / 中国实验血液学杂志

This study was aimed to investigate the expression of p53-inducible gene 3 (PIG-3) in diffuse large B cell lymphoma (DLBCL) and the relationship between PIG-3 and the pathogenesis of lymphoma. The expression of PIG-3 in 20 patients with DLBCL and 20 healthy adults (as a control group) was detected by Western blot and RT-PCR. The results showed that the expression of PIG-3 protein in patients with DLBCL was significantly lower than that in controls, but the expression of PIG-3 was higher after chemotherapy for 6 months than that before chemotherapy. RT-PCR detection demonstrated that the size of PIG-3 amplified product is 1285 bp, which is coincident with theoretic value. It is concluded that the down-regulation of PIG-3 expression may be closely related to pathogenesis of DLBCL, so the PIG-3 gene can considered as a important marker for judging therapeutic efficacy and prognosis of patients with DLBCL.

Alteration of plasma interleukin-18 level in leukemia patients and its clinical significance / 中国实验血液学杂志

To explore the alteration of plasma level of IL-18 in patients with leukemia before and after chemotherapy and its clinical significance, the plasma level of IL-18 was determined with ELISA method before and 2 weeks after chemotherapy in 37 leukemia patients, and 18 normal individuals. The results showed that the plasma IL-18 level (153.34 +/- 50.74 pg/ml) in leukemia patients was similar to the level (135.82 +/- 47.00 pg/ml) in normal control, and the IL-18 level in ALL patients was significantly increased (173.3 +/- 34.4 pg/ml), while the IL-18 level in CML patients (111.8 +/- 50.5 pg/ml) was lower than normal level. After chemotherapy, the IL-18 level (100.89 +/- 50.07 pg/ml) was significantly lower than normal level and oneself before treatment. It is concluded that plasma IL-18 levels in leukemia patients are un-homogeneous and IL-18 production decreased after chemotherapy, and immunologic hypofunction in patients with chemotherapy might be related with the decrease of IL-18 and related cytokines.

Interleukin-18 and its related cytokines in plasma of patients with idiopathic thrombocytopenic purpura / 中国实验血液学杂志

To explore the role of immune regulating cytokines in pathogenesis of the idiopathic thrombocytopenic purpura (ITP) and its clinical significance, the levels of IL-18, TNF-alpha and Sc5b-9 in plasma of 32 ITP patients and 18 normal individuals were detected using ELISA methods. The results showed that IL-18, TNF-alpha and sC5b-9 levels in plasma of ITP patients were higher than that in normal individuals. The level of IL-18 was positively correlated with the levels of TNF-alpha and sC5b-9. In conclusion, The rising levels of the IL-18, TNF-alpha and sC5b-9 were correlated with disorder of Th1/Th2 subsets, and may contribute to the immune dysfunction in ITP patients. The dynamic observation of these cytokines may be useful in directing the clinical treatment for ITP patients.
