Using radial pulse wave as hemodynamic measurements to quantify effects of acupuncture therapy for patients with traumatic brain injury and ischemia stroke.

Background and aim: Traumatic Brain Injury (TBI) and stroke are major sources of death and disability worldwide. Acupuncture has been used as a supplemental therapy for patients with TBI and stroke. This study was aimed to evaluate the effects of acupuncture therapy for patients with TBI and stroke by radial pulse spectrum. Experimental procedure: 22 patients (6 TBI and 16 stroke) were enrolled and underwent radial pressure wave measurement before and after acupuncture treatment at Dubi (ST-35), Zusanli (ST-36) and Jiexi (ST-41). The harmonic analysis of the radial pressure wave was calculated and transformed into Fourier series coefficients Cn, Pn and the variation coefficient CnCV. Results: After acupuncture, systolic blood pressure, heart rate, and Glasgow Coma Scale changed very slightly. The harmonic index C4, C7, C9, C10, C3CV and C5CV had significant increases. (P < 0.05) After 3-week course acupuncture treatment, systolic blood pressure, C7, C8, C9, C10 and P10 had significant increases. (P < 0.05). Conclusion: Harmonic analysis of radial pulse waves may detect earlier circulatory system changes of acupuncture treatment before they were evident with other hemodynamic readings or scale.

Novel anti-aging herbal formulation Jing Si displays pleiotropic effects against aging associated disorders.

Common characteristics of aging include reduced somatic stem cell number, susceptibility to cardiac injuries, metabolic imbalances and increased risk for oncogenesis. In this study, Pleiotropic anti-aging effects of a decoction Jing Si herbal drink (JS) containing eight Traditional Chinese Medicine based herbs, with known effects against aging related disorders was evaluated. Adipose derived mesenchymal stem cells (ADMSCs) from 16 week old adult and 24 month old aging WKY rats were evaluated for the age-related changes in stem cell homeostasis. Effects of JS on self-renewal, klotho and Telomerase Reverse Transcriptase expression DNA damage response were determined by immunofluorescence staining. The effects were confirmed in senescence induced human ADMSCs and in addition, the potential of JS to maintain telomere length was evaluated by qPCR analysis in ADMSCs challenged for long term with doxorubicin. Further, the effects of JS on doxorubicin-induced hypertrophic effect and DNA damage in H9c2 cardiac cells; MPP+-induced damages in SH-SY5Y neuron cells were investigated. In addition, effects of JS in maintaining metabolic regulation, in terms of blood glucose regulation in type-II diabetes mice model, and their potential to suppress malignancy in different cancer cells were ascertained. The results show that JS maintains stem cell homeostasis and provides cytoprotection. In addition JS regulates blood glucose metabolism, enhances autophagic clearances in neurons and suppresses cancer growth and migration. The results show that JS acts on multiple targets and provides a cumulative protective effect against various age-associated disorders and therefore it is a candidate pleiotropic agent for healthy aging.

Antimicrobial and Immunomodulatory Activity of Herb Extracts Used in Burn Wound Healing: "San Huang Powder".

"San Huang Powder," a nonsterile milled herb powder, is frequently used to treat burn wounds in traditional Chinese herbal medicine. However, treating a wound with a nonsterile dressing or reagent is not compatible with the current guidelines in modern medicine. Therefore, we investigated the bactericidal and anti-inflammatory activities of four herb extracts used in "San Huang Powder" in vitro. Meanwhile, an in vivo porcine model with superficial second-degree burns was used for the experiments since the size and skin composition of pigs are the closest to that of the human body. The minimal bactericidal concentration (MBC) of the herb extracts was determined. The in vitro assay indicated that Rhubarb and Phellodendron bark extracts decreased the levels of inflammatory cytokines, IL-8, and GM-CSF on LPS-induced HMEC-1 cells. In accordance with this result, the histopathological evaluation results showed that the efficacy of "San Huang Powder" containing both herb materials was much better than the group without Rhubarb. Our results not only provide a basis to understand why "San Huang Powder" has been used to clinically treat wounds without sterilization directly since ancient times but also show the advantages of using multiple herb materials simultaneously on wound sites to prevent infection during treatment. Rhubarb is the recommended ingredient involved in the preparation of "San Huang Powder" to ensure the healing efficacy of burn wounds.

The curative effects of the traditional Chinese herbal medicine "Jinchuang ointment" on excisional wounds.

BACKGROUND: "Jinchuang ointment" is a traditional Chinese herbal medicine for external incised wounds. This herbal medicine has been successfully used to treat patients with diabetic foot ulcers and pressure sores in Taiwan for several decades. We previously examined its biological activities on cell-based in vitro assay platforms. Because some patients refused to use animal-derived ingredients ointment during our clinical practice, the efficacy of plant oil-based reconstituted "Jinchuang ointment" was also investigated. METHODS: A porcine excisional wound model was established and used to evaluate its efficacy in vivo in this study. Besides, an unusual clinical case is also present. RESULTS: As judged from the wound appearance of animal studies on day 14 and the results of blood flow flux at the wound sites on day 28, "Jinchuang ointment" accelerated wound closure significantly better than the control group. CONCLUSIONS: The results from clinical treatment, histopathological evaluation, and the animal study showed that "Jinchung ointment" promotes wound healing significantly better than the control group. Also, sesame oil-reconstituted ointment can be a choice for patients who refuse to use lard-containing ointment.

Effects of Moxibustion on the Levels of Insulin-Like Growth Factor 1: A Pilot Study.

Moxibustion () is a traditional Chinese medicine therapy performed using Artemisia argyii. Zusanli (, ST36) is an acupoint in the stomach meridian, long associated in ancient Chinese medical practices with the extension of life span when moxibustion is applied to it. The aim of this study was to investigate changes in insulin-like growth factor 1 (IGF-1) levels after application of moxibustion to ST36. Four healthy men and women participated in this 28-day trial and were randomly divided into 2 groups. Group A received moxibustion treatment from days 1 to 14, while group B received moxibustion treatment from days 15 to 28. Blood samples were taken 5 times during this study to measure serum IGF-1 (s-IGF-1) levels. The s-IGF-1 levels increased in both groups after 7 and 14 d of moxibustion therapy (group A: 11.02% [7 d] and 29.65% [14 d]; group B: 169.12% [7 d] and 274.85% [14 d]). After moxibustion therapy had been completed (day 14), s-IGF-1 levels continued to increase in group A (increases on day 21 and day 28 were 53.19% and 61.45%, respectively). There were no adverse events in either group. The s-IGF-1 levels were significantly raised in both groups after 7 and 14 d of moxibustion therapy. Moreover, once therapy had been completed, s-IGF-1 levels continued to increase in group A up to 14 d after the treatment.

Peptides corresponding to the predicted heptad repeat 2 domain of the feline coronavirus spike protein are potent inhibitors of viral infection.

BACKGROUND: Feline infectious peritonitis (FIP) is a lethal immune-mediated disease caused by feline coronavirus (FCoV). Currently, no therapy with proven efficacy is available. In searching for agents that may prove clinically effective against FCoV infection, five analogous overlapping peptides were designed and synthesized based on the putative heptad repeat 2 (HR2) sequence of the spike protein of FCoV, and the antiviral efficacy was evaluated. METHODS: Plaque reduction assay and MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) cytotoxicity assay were performed in this study. Peptides were selected using a plaque reduction assay to inhibit Feline coronavirus infection. RESULTS: The results demonstrated that peptide (FP5) at concentrations below 20 µM inhibited viral replication by up to 97%. The peptide (FP5) exhibiting the most effective antiviral effect was further combined with a known anti-viral agent, human interferon-α (IFN-α), and a significant synergistic antiviral effect was observed. CONCLUSION: Our data suggest that the synthetic peptide FP5 could serve as a valuable addition to the current FIP prevention methods.
