Objective To observe the effect of the diagnoses and therapies to the lateral epicondylitis of humerus based on the principle of myofacial trigger points pain. Methods 35 patients are diagnosed as lateral epicondylitis of humerus, mainly involved lateral muscle groups of elbow. They were treated with a wet needling combined with a stretch therapy and some medications, such as multi-vitamin etc. Results All of the patients are very effective. Pain scale before and after treatment is 4.4?1.03 and 1.2?0.4(P

The administration of mesenchymal stem cells (MSCs) as a therapy for liver disease holds great promise. MSCs can differentiate into hepatocytes, reduce liver inflammation, promote hepatic regeneration and secrete protective cytokines. However, the risks of iatrogenic tumor formation, cellular rejection and infusional toxicity in MSC transplantation remain unresolved. Accumulating evidence now suggests that a novel cell-free therapy, MSC-secreted exosomes, might constitute a compelling alternative because of their advantages over the corresponding MSCs. They are smaller and less complex than their parent cells and, thus, easier to produce and store, they are devoid of viable cells, and they present no risk of tumor formation. Moreover, they are less immunogenic than their parent cells because of their lower content in membrane-bound proteins. This paper reviews the biogenesis of MSC exosomes and their physiological functions, and highlights the specific biochemical potential of MSC-derived exosomes in restoring tissue homeostasis. In addition, we summarize the recent advances in the role of exosomes in MSC therapy for various liver diseases, including liver fibrosis, acute liver injury and hepatocellular carcinoma. This paper also discusses the potential challenges and strategies in the use of exosome-based therapies for liver disease in the future.

Objective: To establish a screening system for anti-metastatic small-molecule compounds based on perinucleolar compartment (PNC) prevalence in liver cancer cells and to investigate its validity. Methods: Polypyrimidine tract-binding protein (PTB) monoclonal antibody was used to measure the PNC prevalence in HepG2, HepG2M, and Huh7 cells, and wound healing assay and transwell assay were used to analyze the migration and invasion abilities of hepatoma cells. HepG2M cells were used as the model for the screening of anti-metastatic small-molecule compounds, and after the treatment with the compounds A1, A4, and E696, qPCR was used to measure the expression of metastasis-related miRNAs (miR-141 and miR-200c). A one-way analysis of variance was used for comparison of data between multiple groups. Results: PTB immunofluorescence assay showed that HepG2M cells had the highest PNC prevalence, followed by Huh7 and HepG2 cells, and PNC prevalence was positively correlated with the metastasis and invasion abilities of hepatoma cells. The PNC prevalence of HepG2M cells was reduced to 22.88% ±4.61% by A1, 14.22% ± 3.05% by A4, and 26.12% ± 4.94% by E696. Wound healing assay showed that the 48-hour scratch ratio increased from 17.70% ± 3.34% to 64.50% ± 2.65%, 83.40% ± 5.10%, and 57.20% ± 3.06% (F = 171.1, P < 0.01), respectively. Transwell assay showed that the number of invasive cells was reduced from 264.33 ± 30.50 to 104.33 ± 13.50, 58.00 ± 11.00, and 111.33 ± 19.50 (F = 59.87, P < 0.01), respectively. The anti-metastatic effect of these three compounds was positively correlated with their ability to destroy PNC. A4 upregulated the expression of miR-141 and miR-200c in a dose-dependent manner, and after HepG2M cells were treated with A4 at a concentration of 5 μM, 10 μM, or 20 μM, the level of miR-141 was increased to 3.61 ± 0.78, 8.12 ± 1.15, and 18.24 ± 2.44 folds (F = 88.01, P < 0.01), respectively, and that of miR-200c was increased to 2.82 ± 0.43, 4.82 ± 0.89, and 10.74 ± 1.22 folds (F = 87.94, P < 0.01), respectively. Conclusion The screening system for anti-metastatic small-molecule compounds based on PNC prevalence can provide an effective technical platform for research and development of anti-metastatic drugs for liver cancer.
