Objective. To explore the effect of autologous stem cell transplantation combined with modified VTD regimen on elderly patients with multiple myeloma and its influence on miRNA cytokines. Methods. The data of 42 elderly patients with multiple myeloma who were treated in our hospital from May 2010 to June 2018 were retrospectively analyzed, and they were divided into the combined group (autologous stem cell transplantation combined with improved VTD scheme, n = 25 ) and the control group (improved VTD scheme, n = 17 ) according to different treatment schemes, and the clinical efficacy of the two groups was compared. The levels of CD3+, CD4+, CD4+/CD8+, and Treg were measured in the two groups. The expression levels of miRNA-15a, miRNA-16, and miRNA-21 in the bone marrow fluid of the two groups were measured before and after treatment. The levels of M protein and myeloma cells in the two groups were detected. Comparing the incidence of adverse reactions between the two groups, the Kaplan-Meier method was used for survival analysis. Results. The total effective rate of the combined group (84.00%) was higher than that of the control group (52.94%), and the difference was statistically significant ( P < 0.05 ). After treatment, the levels of CD3+, CD4+, CD4+/CD8+, Treg, miRNA-15a, and miRNA-16 in the combined group were higher than those in the control group, and the levels of miRNA-21, M protein, and myeloma cells were lower than those in the control group, with statistical significance ( P < 0.05 ). There was no significant difference in adverse reactions between the two groups ( P > 0.05 ). The first, second, and third year survival rates of group A (96.00%, 88.00%, and 80.00%) were significantly higher than those of the control group (70.59%, 58.82%, and 47.06%), and the difference was statistically significant ( P < 0.05 ). Conclusion. Autologous stem cell transplantation combined with a modified VTD regimen can effectively improve the immune function and survival rate of elderly patients with multiple myeloma, which is safe and effective.

Objective. To explore the effect of a moxibustion instrument combined with intermediate frequency electrostatic therapy on pain and joint function in elderly patients with cold-dampness arthritis (KOA). Method. 200 patients with cold-dampness KOA treated in our hospital from May 2019 to September 2021 were selected. According to the random number table method, they were divided into the observation group ( n = 100 ) and control group ( n = 100 ). The observation group was treated with moxibustion combined with medium-frequency treatment, and the control group was treated with medium-frequency treatment. The clinical effects of the two groups were compared. The joint functions of the two groups were evaluated by the visualization scale of the osteoarthritis index (WOMAC index) of McMaster University in Western Ontario. The TCM symptom scores of the two groups were evaluated according to the guiding principles for clinical research of new traditional Chinese medicine. The visual analogue scale (VAS) was used to evaluate the pain degree of the two groups, and the microcirculatory blood perfusion (MBPU) and interleukin-1 were compared between the two groups, β (IL-1β) and tumor necrosis factor-α (TNF-α). The levels of matrix metalloproteinase-1 (MMP-1), serum bone morphogenetic protein-2 (BMP-2), cartilage oligomeric matrix protein (COMP), and serum type II collagen C-terminal peptide (CTX-II) were assessed by the comprehensive quality of life questionnaire-74. Result. The total effective rate of the observation group (92.00%) was higher than that of the control group (76.00%), and the difference was statistically significant ( P < 0.05 ) in β and TNF-α. The levels of MMP-3, BMP-2, comp, and CTX-II and the improvement of quality of life score in the control group were better than those in the control group ( P < 0.05 ). Conclusion. Moxibustion instrument combined with intermediate frequency electrostatic therapy can effectively improve the knee joint function, pain, blood perfusion, inflammatory reaction, and cartilage damage of the elderly patients with cold-dampness-type knee arthritis, and the therapeutic effect is good.
