摘要：Aim This study aimed to investigate the clinical efficacy of externally applied Traditional Chinese Medicine (TCM) on diabetic foot. Methods We searched the China Knowledge Network (CNKI), Wanfang Database, PubMed and Web of Science from inception to July 31, 2022, to find all randomized control trials (RCTs) related to externally applied TCMs in diabetic foot treatment. Information about the total effective rate, healing rate, and healing time were extracted. In addition, the relative risk (RR)/odds ratio (OR) or standardized mean difference (SMD) and 95?% confidence interval (CI) were calculated. Results Finally, a total of 34 RCTs including 3758 patients were included in this meta-analysis. There were 5 articles that reported hydropathic compress with astrogalin, 14 articles that reported MEBO burn cream, 9 articles that reported compound cortex phellodendri liquid and 6 articles that reported Shengji Yuhong ointment. Compared with the basic treatment, the externally applied TCM (astrogalin, MEBO burn cream, compound cortex phellodendri liquid and Shengji Yuhong ointment) combined with basic treatment improved the total effective rate (RR?=?1.31 [1.20, 1.42], P?<?0.0001) and healing rate (RR?=?1.84 [1.56, 2.17], P?<?0.0001) and shortened the healing time (SMD?=???2.51 [??3.39, ??1.63], P?<?0.0001). Conclusion Our systematic review and meta-analysis revealed that common TCM applied externally could significantly improve the clinical efficacy comparing to the basic treatment.

摘要：New hopes in cell therapies have steadily arisen with ongoing progress in stem cell research, and innumerable conditions could be now treated and cured, from musculoskeletal injuries to diabetes to cardiac failure, to cite but a few, with the appropriate stem cells available. Arguably, the ideal therapeutic stem cells are those that naturally heal, repair, and replenish the target tissue in life, and research from the last decades has uncovered the presence of such committed, specialized stem cells in most organs. However, these cell lineage-specific regenerative cells are rare, difficult to identify and purify, and virtually impossible to culture for amplification as functionally intact, undifferentiated units. For this reason, and with the notable exception of hematopoietic stem cells, these are not presently amenable to clinical utilization.From the 1980's, Prof. Rongxiang Xu developed the theory that some of the pluripotent stem cells that build the embryo in early development also establish through adult life a minor subset of cells which, although seemingly terminally differentiated, retain strong multi-lineage developmental potential. He called these "potential regenerative cells" (PRCs), proposing these can be recruited into tissue repair and regeneration when no other progenitor cells are available (1). Although this hypothesis could not be fully tested experimentally at the time, it later turned out as strikingly visionary: on the one hand, it was demonstrated that mature cells can be reprogrammed into stem cells in culture, a discovery rewarded by attribution of the Nobel Prize in Medicine or Physiology in 2012 (2). Hence, transition from a functional, specialized cell back into a naïve, unbiased stem cell is, biologically, feasible and might explain the persistence of Rongxiang Xu's PRCs in adult organs. Another example in support of PRC existence refers to mesenchymal stem cells. MSCs are multipotent cells that can differentiate in culture into bone, cartilage, fat, tendon, muscle, and indirectly support, via growth factor secretion, the regeneration of multiple other tissues (3). This extraordinary potential has stimulated the use of MSCs in over 2000 clinical trials in attempts to treat multiple conditions in cardiology, orthopaedics, cancerology, nephrology, and many other specialties including medical immunology, since MSCs are also immunosuppressive (see clinicaltrials.gov). Despite such a popularity, progress in MSC science has long been hindered by the unknown identity of native, tissueresident mesenchymal stem cells, since these cells appear and expand in extended cultures of total, unselected cell populations dissociated from bone marrow, adipose tissue, umbilical cord, or other organs. Put in other words, MSCs are normally produced in vitro from elusive, rare ancestor cells that have long resisted description. This changed when multicolour, stringent flow cytometry cell sorting and sensitive differentiation assays were used for MSC prospective identification. In full support of the PRC concept proposed by Rongxiang Xu, innate tissue resident mesenchymal stem cells turned out to be differentiated perivascular cells of documented function. Pericytes, which enwrap capillaries and microvessels, regulate blood pressure and control angiogenesis. Equivalent cells populate the tunica adventitia at the periphery of larger blood vessels. Both purified pericytes and adventicytes give rise to bona fide mesenchymal stem cells when cultured in vitro (4,5). The use of transgenic reporter mice, in which cell lineages can be tracked dynamically, has confirmed the progenitor cell potential of perivascular cells in vivo (6). In aggregate, all these results have confirmed that differentiated cells can be reprogrammed into regenerative cells in culture and in the living organism, thus supporting Dr Xu's hypothesis on the existence of PRCs in adult organs.Professor Rongxiang Xu contributed to the development of formulations, mostly inspired by traditional Chinese medicine, for stem cell (PRC) stimulation in situ and in culture. Such a supplement, for instance, named GIC, was claimed to regenerate the gastrointestinal mucosa, as well as nerves, in culture. More recently, the LifeRegen Inc. company developed a line of products inspired by Dr Xu's research and patents were issued for a proprietary blend of natural ingredients produced via an original manufacturing process. All LifeRegen protocols rely on the infusion of combined black sesame oil, skullcap root, and beeswax. These products are considered GRAS (generally recognized as safe) by the FDA, and represent a scientific breakthrough merging ancient Chinese medicine recipes and Rongxiang Xu's groundbreaking results that are, moreover, being supported and extended by ongoing current research. More precisely, GI Balance and Juvenate Skincare are LifeRegen's proprietary formulations developed to nurture and renew the gut lining and create a cellular, rejuvenation promoting protective barrier for the skin, respectively.The insightful Prof. Rongxiang Xu predicted that some of the cells that constitute developed organs retain stem potential, and hence can be qualified as "potentially regenerative cells", and devised formulations that can stimulate such cells into tissue regeneration. He left us a rich legacy of centers at prestigious institutions, such as the Rongxiang Xu Center for Regenerative Therapeutics at Beth Israel Deaconess Medical Center in Boston, the Rongxiang Xu Center for Regenerative Life Science at the University of Southern California, and the Rongxiang Xu College of Health and Human Services at Cal state LA.The LifeRegen company has resumed and considerably amplified and diversified Dr Xu's approach to regenerative medicine, and is now sponsoring clinical studies for the GI Balance supplement that in previous published research enabled regeneration and rejuvenation of the entire gut mucosa within 6 months. In a more fundamental investigation perspective, PRCs have been prospectively identified and characterized in depth, for instance as pericytes and other perivascular elements, and can be purified to homogeneity and in large numbers from multiple organs (3). This opens unforeseen possibilities in regenerative medicine research whereby such well-characterized potential regenerative cells can be selected from the bone marrow, pancreas, skin, adipose tissue and other organs and treated with natural supplements for enhanced proliferation, migration, and differentiation. Such protocols should be initialized in culture and further developed in vivo by transplantation into relevant animal hosts. In perspective are novel biomolecular manoeuvres to drive the improved healing and replenishment of, for instance but not exclusively, cardiovascular, musculoskeletal, and epithelial tissues.

摘要：The porcine model was used to investigate the wound healing process. 116 partial and full-thickness wounds were induced on the back of the animals using the CO2 Three local dressing agents were tested: Povidone Iodine, Silver Sulphadiazine and MEBO ointments. The following parameters were evaluated: physical examination, photography, pH, transepidermal water loss and moisture of the wound, planimetry and histological assessment of injury. The measurement of different parameters revealed that partial-thickness burn wounds were better assessed using Transepidermal Water Loss (TEWL), while full-thickness ones are better assessed using planimetry, measuring the surface of the wound. MEBO significantly accelerates the wound healing process of partial- (inflicted by CO2 Laser) and full-thickness excised wounds when compared to other local agents applied on wounds similar in size, extent and cause and the control group.

摘要：Background:Hand-foot syndrome (HFS), also known as palmoplantar erythrodysesthesia, is a common adverse effect of the fluoropyrimidine chemotherapy agent capecitabine. Hand-foot syndrome of any grade is reported to affect 43% to 71% of patients treated with single-agent capecitabine chemotherapy. Although not life-threatening, it can have adverse effects on the quality of life (QoL) and daily living activities of a patient.  Sometimes the dose interruptions and reductions required after observation of HFS can also impact on dose intensity and treatment outcomes.  As an option for the treatment of this case, we would reported our preliminary study of the effectiveness of moist exposed burn ointment (MEBO) for stage II and III HFS.   Methods:  We will evaluate the clinical sign and symptoms of hand foot syndrome grade II and III associated with capecitabine as adjuvant chemotherapy agent on advanced stage colorectal cancer.  All patients with HFS will treated with topical MEBO twice daily, the clinical improvement of the symptoms will be recorded.   Results: We reported 8 cases of grade II and III hand foot syndrome, 2 patients were grade III HFS and the others were grade II.  These symptoms occurred after 2 until 3 months after capecitabine administration for locally advanced (stage III) colonic adenocarsinoma.  Topical MEBO were used twice a day for 3 months, pain reduction was achieved with no capicetabine dose interruption and reduction during chemotherapy period.  Allergic reaction was not found during and after MEBO application in this case.   Conclusion:Moist exposed burn ointment was an effective treatment option in managing hand foot syndrome, better option in reducing the pain without interrupting the capecitabine doses.
