In the paper, the process of human body producing Trimethylamine-N-oxide (TMAO) under the role of intestinal microbes has been analyzed, and the ways to reduce the level of TMAO which can increase the incidence of heart disease has been designed. The expected result is that the level of TMAO in plasma is successfully reduced by regulating intestinal microbes. This paper can provide useful information for further studies in self-healing therapy by regulating intestinal microbes.</p> Xingmei Jin Copyright (c) 2023 Xingmei Jin https://creativecommons.org/licenses/by-nc/4.0 2023-04-19 2023-04-19 13 1 1 4 10.18282/pmr.v10i2.2365 https://ojs.piscomed.com/index.php/PMR/article/view/2777 <p>Objective To study the therapeutic effect of Xiaoyao Pill combined with intense pulsed light on stable chloasma. Methods 80 patients with stable chloasma in Shaanxi People's Hospital from September 2018 to September 2019 were enrolled in this prospective randomized controlled study. Randomly divided into control group and observation group, 40 cases in each group. The control group was treated with APT570; The observation group was treated with APT570 combined with oral Xiaoyao Pill Concentrated Pill. Follow-up for 8 months, the therapeutic effects of the two groups were compared. Chi-square test was performed on the data. Results The effective rate of the observation group was 95%, which was higher than that of the control group by 75% (P &lt; 0.05). Conclusion During the treatment of chloasma, APT570 combined with Xiaoyao Pill, a traditional Chinese medicine, can significantly improve the effective rate, reduce the recurrence rate and significantly improve the facial skin quality, which has important clinical experience value.</p> Guodong Wang Jing Zhang Wenjie Gao Copyright (c) 2023 Guodong Wang, Jing Zhang, Wenjie Gao https://creativecommons.org/licenses/by-nc/4.0 2023-04-19 2023-04-19 13 1 5 9 10.18282/pmr.v10i2.2777 https://ojs.piscomed.com/index.php/PMR/article/view/2622 Natural Killer Cells (NK cells) based immunotherapy involving a variety of immune checkpoint inhibitors (ICIs) is becoming increasingly common and has achieved considerable success. However, at the same time, it also faces some huge burning problems. Cancer immunotherapy with NK cells enables the precise elimination of cancer cells. Besides, NK cells can be massively expanded in vitro and do not lead to graft-versus-host-disease (GVHD). Furthermore, ICIs are capable to augment the tumoricidal capacity of NK cells. These characteristics make NK cells dominated immunotherapy a key player in cancer treatment.

We performed a bioinformatic analysis of the prognostic value and immune infiltration correlation of PECAM-1 in breast cancer<strong>.</strong> The results showed that there were significant differences in PECAM-1 expression levels between breast invasive carcinoma tissues and adjacent normal tissues. The high expression of PECAM-1 was significantly related to favorable overall survival, progression-free survival and distant metastasis free survival in patients with breast cancer. There were significantly positive correlations with the levels of infiltrated B cell, CD4+T cells, CD8+ T cells, neutrophils, macrophages, and dendritic cells in breast cancer. In summary, the expression of PECAM-1 can serves as a prognostic biomarker in breast invasive carcinoma and is correlated with immune infiltrates.</p> Qingfang Yue Yuan Zhang Fei Cao Fei Wang Copyright (c) 2023 Qingfang Yue, Yuan Zhang, Fei Cao, Fei Wang https://creativecommons.org/licenses/by-nc/4.0 2023-04-19 2023-04-19 13 1 15 20 10.18282/pmr.v10i2.2771 https://ojs.piscomed.com/index.php/PMR/article/view/2772 <p><strong>Objective</strong><strong><span style="font-family: 'Times New Roman';">: </span></strong>To evaluate the therapeutic effect and safety of acupuncture on Parkinson's disease (PD) with orthostatic hypotension (OH) patients. <strong>Method</strong><strong><span style="font-family: 'Times New Roman';">s</span></strong><strong><span style="font-family: 'Times New Roman';">: </span></strong>A randomized controlled clinical trial was used to observe the efficacy of acupuncture in the treatment of 51 PD with OH patients.
