To systematically review the incidence rate of adverse drug reaction/event by Qingkailing injection. Such databases as the PubMed, EMbase, the Cochrane library, CNKI, VIP WanFang data and CBM were searched by computer from foundation to July 30, 2015. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data and cross check data. Then, Meta-analysis was performed by using the R 3.2.0 software, subgroup sensitivity analysis was performed based on age, mode of medicine, observation time and research quality. Sixty-three studies involving 9,793 patients with Qingkailing injection were included, 367 cases of adverse reactions/events were reported in total. The incidence rate of adverse reaction in skin and mucosa group was 2% [95% CI (0.02; 0.03)]; the digestive system adverse reaction was 6% [95% CI(0.05; 0.07); the injection site adverse reaction was 4% [95% CI (0.02; 0.07)]. In the digestive system as the main types of adverse reactions/events, incidence of children and adults were 4.6% [0.021 1; 0.097 7] and 6.9% [0.053 5; 0.089 8], respectively. Adverse reactions to skin and mucous membrane damage as the main performance/event type, the observation time > 7 days and ≤ 7 days incidence of 3% [0.012 9; 0.068 3] and 1.9% [0.007 8; 0.046 1], respectively. Subgroup analysis showed that different types of adverse reactions, combination in the incidence of adverse reactions/events were higher than that of single drug, the difference was statistically significant (P < 0.05). This study suggested the influence factors of adverse reactions occur, and clinical rational drug use, such as combination, age and other fators, and the influence factors vary in different populations. Therefore, clinical doctors for children and the elderly use special care was required for a clear and open spirit injection, the implementation of individualized medication.

There has been an increasing interest in recent years on mesenchymal stem cell (MSC). It is well known that MSCs are capable of self-renewal and differentiating into many cell lineages. MSC can be expended to a large quantity that is required for clinical transplantation. Recent studies show that MSC have potential application in immune diseases due to their unique immunologic characteristics, such as low immunogenicity and immunoregulatory function. But their immunoregulatory mechanism is not yet clear. This review discusses the advances in researches on the mechanism of MSCs' immunoregulatory function and potential clinical application in immune disease and organ transplantation.

OBJECTIVETo investigate the feasibility of serum pharmacology in evaluating the antitumor effect of Chinese medicine (CM) of Fuzheng Guben (supporting the healthy energy and strengthening the body's resistance to pathogens), the effects of Fuzheng Yiliu Decoction (FYD), a typical prescription of Fuzheng Guben, on proliferation and apoptosis of hepatoma cells in vitro were observed by two methods with serum pharmacology and traditional pharmacology, respectively.
METHODSHepG2 cells were treated with FYD-containing serum or crude FYD extract in vitro. The proliferation rate was determined by methyl thiazolyl tetrazolium (MTT) assay. Cell cycle and apoptosis rate was performed by flow cytometry. And the levels of interleukin-2 (IL-2) and tumor necrosis factor α (TNF-α) in FYD-containing serum were detected by radioimmunoassay.
RESULTSFYD-containing serum remarkably inhibited proliferation and induced apoptosis of hepatoma cells at least by promoting the production of IL-2 and TNF-α in vivo. On the contrary, crude FYD extract promoted the proliferation and did not induce cell apoptosis.
CONCLUSIONThe results by serum pharmacology were accordant with those of our previous animal and clinical trials which indicates that serum pharmacology is a reasonable and feasible method for the evaluation of the antitumor effect of herbs of Fuzheng Guben.

Fibrosis is the common end stage of most liver diseases. Unfortunately, there is no effective treatment available currently. This study was designed to evaluate the effect of Flk1+ mesenchymal stem cells (MSC) from murine bone marrow (Flk1 + MSC) on fibrosis formation induced by carbon tetrachloride (CCl4). In this study Flk1+ MSC were isolated from bone marrow of male BALB/c mice. A CCl4 induced hepatic fibrosis model was used. Flk1+ MSC were systemically infused immediately or one week after the female mice were challenged with CCl4. Fibrosis index and donor cell engraftment were assessed two or five weeks after CCl4 challenge. We found that Flk1+ MSC transplantation immediately, but not one week after exposure to CCl4, significantly reduced CCl4-induced liver damage and collagen deposition. In addition, levels of hepatic hydroxyproline and serum fibrosis markers (HA, P-III-P) in mice receiving immediate Flk1+ MSC transplantation after CCl4 challenge were significantly lower compared to those of control mice. More importantly, histological examination suggested that hepatic damage recovery was much better in these immediately Flk1+ MSC-treated mice. Immunofluorescence, PCR, and fluorescence in situ hybridization (FISH) analysis revealed that donor cells engrafted into host liver, had epithelium-like morphology and expressed albumin (ALB), although at low frequency. In conclusion Flk1+ MSC might initiate endogenous hepatic tissue regeneration, engraft into host liver in response to CCl4 injury, and ameliorate its fibrogenic effects.

OBJECTIVETo investigate whether human adipose derived adult stem (hADAS) cells can differentiate into endothelial cells.
METHODSStem cells were isolated and expanded from adipose tissue and then induced to differentiate into cells of osteogenic, adipogenic and neurogenic lineages in vitro. hADAS cells were induced with vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) to endothelial cells differentiation. hADAS cells were intravenously injected into mouse hindlimb ischemic models to test their ability to differentiate endothelial cells in vivo.
RESULTShADAS cells were easily isolated and expanded in vitro. They had the ability to differentiate into osteogenic, adipogenic and neurogenic lineages. The cells expressed vascular endothelial growth factor receptor-2 (VEGFR-2, Flk1), and expressed endothelial markers when cultured with VEGF and bFGF. In response to local cues, hADAS cells in vivo differentiate into endothelial cells that contributed to neoangiogenesis in hindlimb ischemia models.
CONCLUSIONSFlk1+ hADAS cells have multipotential not only similar to bone marrow mesenchymal stem cells, but also exhibiting characteristics of endothelial progenitor cells. They may be a potential source of endothelial cells for cellular pro-angiogenic therapies.

OBJECTIVETo study the inhibitory effect of Fuzheng Yiliu Granule (FYG) on hepatocellular cancer (HCC) and investigate the mechanism mediating its bioactivity.
METHODSH22 tumor-bearing ICR mice were treated with FYG [3.6 g/(kg·d)] for 5 days. Tumor volume and tumor weight, percentages of CD3(+), CD4(+), CD8(+), and natural killer (NK) cells in peripheral blood, tumor apoptosis and serum levels of interleukin-2 (IL-2), and tumor necrosis factor-α (TNF-α) were evaluated. FYG-containing serum was prepared from SD rats treated for 7 days [high dose 3.6 g/(kg·d); middle dose 1.8 g/(kg·d); low dose 0.9 g/(kg·d)]. Cell cycle, cell viability, and apoptosis were evaluated after HepG2 cell line was cultured in FYG-containing serum for 48 h. The levels of IL-2 and TNF-α in FYG-containing serum were also determined.
RESULTSFYG produced a potent antitumor effect (P<0.01) and induced marked apoptosis of the tumor tissue (P<0.05). Mice treated with FYG had higher percentages of CD3(+) and CD4(+) (P<0.05), and more NK cells (P<0.01) in the peripheral blood than those in the animals treated with normal saline. Mice receiving FYG had the highest serum levels of IL-2 and TNF-α (P<0.01). High-dose FYG-containing serum significantly decreased HepG2 cell viability, inhibited cell proliferation (P<0.05), and induced apoptosis (P<0.01). In addition, the levels of IL-2 and TNF-α of high-dose-containing serum were higher than the blank serum (P<0.01).
CONCLUSIONFYG could inhibit HCC growth by regulating immune function and inducing apoptosis of tumor cells in vivo and in vitro.

BACKGROUNDExposure of cells to sublethal concentrations of hydrogen peroxide (H2O2) can alleviate subsequent oxidative stress-induced apoptosis. We assessed the effects of H2O2 preconditioning on the therapeutic potential of human umbilical cord Wharton's Jelly mesenchymal stem cells (WJ-MSCs) in a murine model of myocardial infarction.
METHODSWJ-MSCs were incubated in the media for 2 hours with or without 200 µmol/L H2O2. Mice underwent left anterior descending coronary artery ligation, and received injection of phosphate buffered saline, 1×10(6) WJ-MSCs, or 1×10(6) H2O2 preconditioned WJ-MSCs 3 hours later via tail vein. Echocardiography was performed 0, 7, 14 and 28 days after surgery, and the mice were euthanized on day 28 for histological analysis. In vitro cytokine concentrations in the WJ-MSC cell supernatant were measured by enzyme-linked immunosorbent assay (ELISA). The effect of WJ-MSC cell supernatant on the migration and proliferation of endothelial cells were observed by transwell migration and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazoliumbromide (MTT) assays.
RESULTSEchocardiographic measurements revealed a significant improvement in the left ventricular contractility of the WJ-MSCs-H2O2 group compared to the WJ-MSCs group. Histological analysis revealed increased neovascularization and reduced myocardial fibrosis in the WJ-MSCs-H2O2 group compared to the WJ-MSCs group. Pretreatment of WJ-MSCs with H2O2 increased the secretion of interleukin-6 (IL-6) into the cell culture supernatant by approximately 25-fold. The culture supernatant from WJ-MSCs-H2O2 significantly increased the migration and proliferation of endothelial cells; these effects could be blocked using an anti-IL-6 antibody.
CONCLUSIONSThis study demonstrates that H2O2 preconditioning significantly enhanced the therapeutic potential of WJ-MSCs, possibly by stimulating the production of IL-6 by WJ-MSCs, which may cause migration and proliferation of endothelial cells and increase neovascularization.
