Key Clinical Message: In outpatient settings, Mycobacterium chelonae complex infection brought on by cosmetic injections are rather uncommon. We came across a case of infection brought on by a commercial stem cell injection. [ABSTRACT FROM AUTHOR]

Background: Photoaging is a degenerative biological process that affects the quality of life. It is caused by environmental factors including ultraviolet radiation (UVR), deep skin burns, smoking, active oxygen, chemical substances, and trauma. Among them, UVR plays a vital role in the aging process. Aim: With the continuous development of modern medicine, clinical researchers have investigated novel approaches to treat aging. In particular, mesenchymal stem cells (MSCs), non‐coding RNAs are involved in various physiological processes have broad clinical application as they have the advantages of convenient samples, abundant sources, and avoidable ethical issues. Methods: This article reviews research progress on five types of stem cell, exosomes, non‐coding RNA in the context of photoaging treatment: adipose‐derived stem cell, human umbilical cord MSCs, epidermal progenitor cells, keratinocyte stem cells, and hair follicle stem cells (HFSCs). It also includes stem cell related exosomes and their non‐coding RNA research. Results: The results have clinical guiding significance for prevention and control of the onset and development of photoaging. It is found that stem cells secrete cytokines, cell growth factors, non‐coding RNA, exosomes and proteins to repair aging skin tissues and achieve skin rejuvenation. In particular, stem cell exosomes and non‐coding RNA are found to have significant research potential, as they possess the benefits of their source cells without the disadvantages which include immune rejection and granuloma formation.

With the rapid development of the mobile device and Internet usage, the mobile banking has seen remarkable growth across the world, especially in the past few years, as one of the emerging financial innovations. This paper attempts to explore the mobile banking services offered by selected commercial Chinese banks. The main data of this study were obtained through the comprehensive evaluation of mobile banking services. The DEMATEL-ANP method was used to evaluate the main factors influencing the adoption of mobile banking. The results show that there is still big space for the improvement of the mobile banking services for the selected Chinese banks. The management significance and suggestions for these banks are also discussed. [ABSTRACT FROM AUTHOR]

Objective: To detect the self-assembly morphology of sodium hyaluronate injection on mica using atomic force microscopy(AFM)., Methods: Atomic force microscopy with nanometer resolution was used to observe the self-assembly morphology of different concentrations of sodium hyaluronate injection on mica at room temperature., Results: The self-assembly morphology of 0.001, 0.01, and 0.1 mg/ml sodium hyaluronate injection on mica featured piebald, reticular and dendritic structures, respectively. At 1 and 5 mg/ml, sodium hyaluronate injection displayed bacilliform and spherical structures on mica, respectively; the diameter and height of the particles of 5 mg/ml sodium hyaluronate was 197.97±78.48 nm and 30.79±18.67 nm, significantly greater than those of 0.1 mg/ml sodium hyaluronate injection (49.52±11.93 nm and 5.37±1.59 nm, respectively, P<0.05)., Conclusion: The self-assembly morphology of sodium hyaluronate injection on mica varies with its concentration. The piebald and reticular structure may facilitate the function of sodium hyaluronate, and the dendritic feature resembles the representative model of diffusion-limited aggregation (DLA).
