Abstract
The metastasis of human osteosarcoma (OS) shows a difficult‑to‑treat clinical scenario and results in decreased quality of life and diminished survival rates. Finding or developing novel treatments to improve the life quality of patients is urgent. Bisdemethoxycurcumin (BDMC), a natural product, was obtained from the rhizome of turmeric (Curcuma longa) and exerts antitumor activities in numerous human cancer cell lines. At present, there is no study showing BDMC effects on OS cell migration and invasion. In the present study, the effects of BDMC on cell migration and invasion of OS U‑2 OS cells were investigated in vitro. Cell viability and proliferation were measured by flow cytometric and MTT assays, respectively. Cell motility, MMP‑2 and ‑9 activity, and cell migration and invasion were assayed by scratch wound healing, gelatin zymography, and Transwell chamber assays, respectively. The protein expression levels were measured by western blotting. BDMC at 20 and 40 µM significantly reduced total cell viability, and BDMC at 5 and 10 µM significantly inhibited cell motility in U‑2 OS cells. BDMC significantly suppressed the activities of MMP‑2 and MMP‑9 in U‑2 OS cells. BDMC suppressed cell invasion and migration after 24 h treatment in U‑2 OS cells, and these effects were in a dose‑dependently manner. Results from western blotting indicated that BDMC significantly decreased the protein expression levels of PI3K/Akt/NF‑κB, PI3K/Akt/GSK3β, and MAPK pathway in U‑2 OS cells. Furthermore, BDMC inhibited uPA, MMP‑2, MMP‑9, MMP‑13, N‑cadherin, VE‑cadherin, and vimentin but increased E‑cadherin in U‑2 OS cells. Based on these observations, it was suggested that BDMC may be a potential candidate against migration and invasion of human OS cells in the future.

Abstract
Human glioblastoma (GBM) is one of the common cancer death in adults worldwide, and its metastasis will lead to difficult treatment. Finding compounds for future to develop treatment is urgent. Bisdemethoxycurcumin (BDMC), a natural product, was isolated from the rhizome of turmeric (Curcuma longa), which has been shown to against many human cancer cells. In the present study, we evaluated the antimetastasis activity of BDMC in human GBM cells. Cell proliferation, cell viability, cellular uptake, wound healing, migration and invasion, and western blotting were analyzed. Results indicated that BDMC at 1.5-3 μM significantly decreased the cell proliferation by MTT assay. BDMC showed the highest uptake by cells at 3 h. After treatment of BDMC at 12-48 h significantly inhibited cell motility in GBM 8401 cells by wound healing assay. BDMC suppressed cell migration and invasion at 24 and 48 h treatment by transwell chamber assay. BDMC significantly decreased the levels of proteins associated with PI3K/Akt, Ras/MEK/ERK pathways and resulted in the decrease in the expressions of NF-κB, MMP-2, MMP-9, and N-cadherin, leading to the inhibition of cell migration and invasion. These findings suggest that BDMC may be a potential candidate for the antimetastasis of human GBM cells in the future.

Abstract
Bisdemethoxycurcumin (BDMC) has biological activities, including anticancer effects in vitro; however, its anticancer effects in human glioblastoma (GBM) cells have not been examined yet. This study aimed to evaluate the tumor inhibitory effect and molecular mechanism of BDMC on human GBM 8401/luc2 cells in vitro and in vivo. In vitro studies have shown that BDMC significantly reduced cell viability and induced cell apoptosis in GBM 8401/luc2 cells. Furthermore, BDMC induced apoptosis via inhibited Bcl-2 (anti-apoptotic protein) and increased Bax (pro-apoptotic proteins) and cytochrome c release in GBM 8401/luc2 cells in vitro. Then, twelve BALB/c-nude mice were xenografted with human glioblastoma GBM 8401/luc2 cancer cells subcutaneously, and the xenograft nude mice were treated without and with BDMC (30 and 60 mg/kg of BDMC treatment) every 3 days. GBM 8401/luc2 cell xenografts experiment showed that the growth of the tumors was significantly suppressed by BDMC administration at both doses based on the reduction of tumor size and weights. BDMC did not change the body weight and the H&E histopathology analysis of liver samples, indicating that BDMC did not induce systemic toxicity. Meanwhile, treatment with BDMC up-regulated the expressions of BAX and cleaved caspase-3, while it down-regulated the protein expressions of Bcl-2 and XIAP in the tumor tissues compared with the control group. This study has demonstrated that BDMC presents potent anticancer activity on the human glioblastoma GBM 8401/luc2 cell xenograft model by inducing apoptosis and inhibiting tumor cell proliferation and shows the potential for further development to the anti-GBM cancer drug.

Abstract
BACKGROUND This study aimed to investigate skin condition, quality of life, and psychological impact of breast cancer patients after radiation therapy. We designed and administered a questionnaire to breast cancer survivors for better understanding the skin sequelae after radiation therapy. METHODS This study performed an anonymous online survey. Invitation join was posted in Facebook groups for Breast Cancer. Content of the questionnaire included basic information and a three-point scale on the degree of skin dryness, sweating, hotness sensation, itchy sensation, presence of pigment deposition, history of severe skin disorder, psychological impact, and quality of life after radiotherapy. Categorical variables were summarized using counts and percentages, and then Mantel-Haenszel chi-square tests, multiple correspondence analysis, Wald chi-square statistics, and logistic regression analyses were performed; P < 0.05 was considered statistically significant. RESULTS In total, 421 breast cancer survivors completed the questionnaire. Among them, 331 (78.62%) reported rarely sweating; 340 (80.76%) reported dry skin; 184 (43.71%) reported itchy skin in addition to dry skin; 336 (79.81%) had severe or mild skin color deposition; and 76 (18.05%) had eczema or contact dermatitis. Dry skin problems were caused by absent sweating and skin dryness in the irradiated skin area, post-RT severe skin disorders, and skin color deposition. Compared with patients sweating normally in the radiation field, patients with absent sweating and hotness sensation in the radiation field had a higher risk of depression. CONCLUSIONS This study showed that breast cancer patients after whole breast radiotherapy may experience skin dryness, hypersensitivity and hyper pigmentation in the irradiated skin area. These "radiation-irritated skin" lesions may induce depressive psychological status and impact the quality of life in breast cancer patients after whole breast radiotherapy.

Abstract
BACKGROUND/AIM Maslinic acid (MA), a pentacyclic triterpene extracted from wax-like coatings of olives, has been shown to reduce cancer cell number through induction of autophagy and apoptosis in many human cancer cells including human leukemia HL-60 cells. In the present study, we investigated whether or not MA affects immune responses in a leukemia mouse model. MATERIALS AND METHODS WEHI-3 cells were intraperitonealIy (i.p.) injected into normal BALB/c mice to develop leukemia. Mice were then treated by i.p. injection with MA at different doses (0, 8, 16 and 32 mg/kg) for 2 weeks. After treatment, all animals were weighed and blood, liver and spleen tissues were weighed. Blood or spleen both were used for determination of cell markers or phagocytosis, natural killer (NK) cell activities and T- and B-cell proliferation, respectively, by using a flow cytometric assay. RESULTS MA did not significantly affect body, liver, and spleen weights. However, MA increased markers of T-cells (at 16 mg/kg treatment) and monocytes (at 32 mg/kg treatment), but reduced B-cell markers (at 8 mg/kg treatment); MA did not significantly affect cell marker of macrophages. Furthermore, MA increased phagocytosis by macrophages from peripheral blood mononuclear cells and peritoneal cavity at 32 mg/kg treatment and increased NK cell activity at target cell:splenocyte ratio of 25:1 but did not affect B- and T-cell proliferation. CONCLUSION MA increased immune responses by enhancing macrophage phagocytosis and NK cell activities in leukemic mice.

Abstract
BACKGROUND/AIM Etomidate, an intravenous anesthetic, has been shown to have anticancer effects, including induction of cell-cycle arrest and apoptosis. However, to our knowledge, there are no reports about the anti-metastasis effects of etomidate on A549 human lung adenocarcinoma cells. MATERIALS AND METHODS The cell viability, cell adhesion, gelatin zymography assay, transwell migration and invasion assay, and western blotting analysis were used to investigate the effects of etomidate on A549 cells. RESULTS In our study, etomidate showed low cytotoxicity, inhibited cell adhesion, and suppressed the migration and invasion in A549 cells. The activity of matrix metallopeptidase 2 (MMP2) was reduced by 48 h treatment of etomidate. Results of western blotting analysis indicated that etomidate down-regulated the expression of protein kinase C, MMP7, MMP1, MMP9, and p-p-38, but up-regulated that of RAS, phosphoinositide 3-kinase, and phosphor-extracellular-signal related kinase after 24 and 48 h treatment, in A549 cells. CONCLUSION Etomidate suppressed the migration and invasion of lung adenocarcinoma A549 cells via inhibiting the expression of MMP1, MMP2, MMP7 and MMP9, and provides potential therapeutic targets for lung cancer treatment.

Abstract
Deguelin, a rotenoid, is isolated from a natural plant species, and has biological activities including antitumor function. In the present study, we investigated the effect of deguelin on the cell adhesion, migration and invasion of NCI-H292 human lung cancer cells in vitro. Cell viability was analyzed by using flow cytometer. Cell adhesion was determined by using the cell-matrix adhesion assay. Wound healing assay was used to examine cell migration. Cell migration and invasion were investigated using a Boyden chamber assay. The protein expression was measured by Western blotting and confocal laser microscopy. The electrophoretic mobility shift assay was used to measure NF-[Formula: see text]B p65 binding to DNA.We selected the concentrations of deguelin at 0, 0.5, 1.0, 1.5, 2.0 and 2.5[Formula: see text][Formula: see text]M and we found that those concentrations of deguelin did not induce significant cytotoxic effects on NCI-H292 cells. Thus, we selected those concentrations of deguelin for metastasis assay. We found that deguelin inhibited cell adhesion, migration and invasion in dose-dependent manners that was assayed by wound healing and transwell methods, respectively. Deguelin decreased the expression of MMP-2/-9, SOS 1, Rho A, p-AKT (Thr308), p-ERK1/2, p-p38, p-JNK, NF-[Formula: see text]B (p65) and uPA in NCI-H292 cells. Deguelin suppressed the expression of PI3K, SOS 1, NF-[Formula: see text]B (p65), but did not significantly affect PKC and Ras in the nuclei of NCI-H292 cells that were confirmed by confocal laser microscopy. We suggest that deguelin may be used as a novel anticancer metastasis of lung cancer in the future.

Abstract
Ouabain, the specific Na+ /K+ -ATPase blocker, has biological activity including anti-proliferative and anti-metastasis effects in cancer cell. There is no study to show ouabain inhibiting cell migration and invasion in human osteosarcoma U-2 OS cells. Thus, we investigated the effect of ouabain on the cell migration and invasion of human osteosarcoma U-2 OS cells. Results indicated that ouabain significantly decreased the percentage of viable cells at 2.5-5.0 μM, thus, we selected 0.25-1.0 μM for inhibiting studies. Ouabain inhibited cell migration, invasion and the enzymatic activities of MMP-2, and also affected the expression of metastasis-associated protein in U-2 OS cells. The cDNA microarray assay indicated that CDH1, TGFBR3, SHC3 and MAP2K6 metastasis-related genes were increased, but CCND1, JUN, CDKN1A, TGFB1, 2 and 3, SMAD4, MMP13, MMP2 and FN1 genes were decreased. These findings provide more information regarding ouabain inhibited cell migration and invasion and associated gene expressions in U-2 OS cells after exposed to ouabain.

Abstract
The aim of the present study was to investigate the cytotoxic effects of bufalin on SCC-4 human tongue cancer cells. Cell morphological changes and viability were examined using phase contrast microscopy and flow cytometry, respectively. The results indicated that bufalin induced morphological changes and reduced total viable cells. Apoptotic cell death was analyzed by DAPI staining and DNA gel electrophoresis; the results revealed that bufalin induced cell apoptosis. Levels of reactive oxygen species (ROS), Ca2+, nitric oxide (NO) and mitochondrial membrane potential (ΔΨm) were measured by flow cytometry, and bufalin was observed to increase Ca2+ and NO production, decrease the ΔΨm and reduce ROS production in SCC-4 cells. In addition, western blotting was performed to detect apoptosis-associated protein expression. The results demonstrated that bufalin reduced the expression of the anti-apoptotic protein B-cell lymphoma 2 (Bcl-2) and increased the expression of the pro-apoptotic protein, Bcl-2-associated X protein. However, bufalin treatment also increased the expression of other apoptosis-associated proteins such as apoptosis-inducing factor and endonuclease G in SCC-4 cells. Based on these findings, bufalin may induce apoptotic cell death via mitochondria-dependent pathways in human tongue cancer SCC-4 cells.

Abstract
Gypenosides (Gyp), the primary components of Gynostemma pentaphyllum Makino, have long been used as a Chinese herbal medicine. In the present study, the effects of Gyp on cell viability, the cell cycle, cell apoptosis, DNA damage and chromatin condensation were investigated in vitro using human oral cancer HSC-3 cells. The results of the present study indicated that Gyp induces cell death, G2/M phase arrest and apoptosis in HSC-3 cells in a dose-dependent manner. It was also demonstrated that Gyp decreased the depolarization of mitochondrial membrane potential in a time-dependent manner. A cDNA microarray assay was performed and the results indicated that a number of genes were upregulated following Gyp treatment. The greatest increase was a 75.42-fold increase in the expression of GTP binding protein in skeletal muscle. Levels of the following proteins were also increased by Gyp: Serpine peptidase inhibitor, clade E, member 1 by 20.25-fold; ras homolog family member B by 18.04-fold, kelch repeat and BTB domain containing 8 by 15.22-fold; interleukin 11 by 14.96-fold; activating transcription factor 3 by 14.49-fold; cytochrome P450, family 1 by 14.44-fold; ADP-ribosylation factor-like 14 by 13.88-fold; transfer RNA selenocysteine 2 by 13.23-fold; and syntaxin 11 by 13.08-fold. However, the following genes were downregulated by GYP: Six-transmembrane epithelial antigen of prostate family member 4, 14.19-fold; γ-aminobutyric acid A receptor by 14.58-fold; transcriptional-regulating factor 1 by 14.69-fold; serpin peptidase inhibitor, clade B, member 13 by 14.71-fold; apolipoprotein L 1 by 14.85-fold; follistatin by 15.22-fold; uncharacterized LOC100506718; fibronectin leucine rich transmembrane protein 2 by 15.61-fold; microRNA 205 by 16.38-fold; neuregulin 1 by 19.69-fold; and G protein-coupled receptor 110 by 22.05-fold. These changes in gene expression illustrate the effects of Gyp at the genetic level and identify potential targets for oral cancer therapy.

Abstract
Cantharidin (CTD) is a natural toxin in beetles of the Mylabris genus (blister beetle), which has been revealed to induce cell death in various types of human cancer cells. However, to the best of our knowledge, no previous studies have investigated the effect of CTD on the expression of genes and their associated signaling pathways in human bladder carcinoma cells. In the present study, CTD-induced cell morphological changes and apoptosis were observed using phase-contrast microscopy and the terminal deoxynucleotidyl transferase dUTP nick end labeling assay, respectively, in TSGH-8301 human bladder carcinoma cells. In addition, a complementary DNA microarray analysis demonstrated that CTD treatment led to a >2-fold upregulation of 269 genes. For example, the DNA damage-associated gene DNA-damage-inducible transcript 3 had a 4.75-fold upregulation. Furthermore, another 286 genes were >2-fold downregulated in response to CTD treatment. Matrix-remodeling associated 5, which is associated with cell migration and invasion, was downregulated 7.98-fold.

Abstract
Deguelin, a naturally occurring rotenoid of the flavonoid family, is known to be an Akt inhibitor, to have chemopreventive activities and anti-tumor effect on several cancers. In this study, investigation to elucidate the effect of deguelin on apoptotic pathways in human lung cancer cells and on the anti-tumor effect in lung cancer xenograft nu/nu mice was performed. In vitro studies, found that deguelin induced cell morphological changes, and decreased the percentage of viability through the induction of apoptosis in H460 lung cancer cells. Deguelin triggered apoptosis in H460 cells was also confirmed by DAPI staining, DNA gel electrophoresis, and Annexin V-FITC staining and these effects are dose-dependent manners. It was also found that deguelin promoted the Ca2+ production and activation of caspase-3 but decreased the level of ΔΨm in H460 cells. Western blots indicated that the protein levels of cytochrome c, AIF, and pro-apoptotic Bax and Bak protein were increased, but the anti-apoptotic Bcl-2 and Bcl-x were decreased that may have led to apoptosis in H460 cells after exposure to deguelin. It was also confirmed by confocal laser microscope examination that deguelin promoted the release of AIF from mitochondria to cytosol. In vivo studies, found that in immunodeficient nu/nu mice bearing H460 tumor xenografts showed that the deguelin significantly suppressed tumor growth. Deguelin might be a potential therapeutic agent for the treatment of lung cancer in the future. This finding might fully support a critical event for deguelin via induction of apoptotic cell death and H460 tumor xenografts model against human lung cancer. © 2015 Wiley Periodicals, Inc.

Abstract
In this study we investigate the molecular mechanisms of caspases and mitochondria in the extrinsic and intrinsic signal apoptosis pathways in human leukemia HL-60 cells after in vitro exposure to 18α-glycyrrhetinic acid (18α-GA). Cells were exposed to 18α-GA at various concentrations for various time periods and were harvested for flow cytometry total viable cell and apoptotic cell death measurements. Cells treated with 18α-GA significantly inhibited cell proliferation and induced cell apoptosis in a dose-dependent manner, with an IC50 value of 100 μM at 48 h. The cell growth inhibition resulted in induction of apoptosis and decreased the mitochondria membrane potential (ΔΨm) and increased caspase-8, -9 and -3 activities. Furthermore, cytochrome c and AIF were released from mitochondria, as shown by western blotting and confirmed by confocal laser microscopy. Western blotting showed that 18α-GA increased the levels of pro-apoptotic proteins such as Bax and Bid and decreased the anti-apoptotic proteins such as Bcl-2 and Bcl-xl, furthermore, results also showed that 18α-GA increased Fas and Fas-L which are associated with surface death receptor in HL-60 cells. Based on those observations, the present study supports the hypothesis that 18α-GA-induced apoptosis in HL-60 cells involves the activation of the both extrinsic and intrinsic apoptotic pathways.

Abstract
OBJECTIVE Sleep deprivation (SD) leads to the disturbance of the estrous cycle. Serotonin, the levels of which increase with SD, has been shown to inhibit luteinizing hormone production and the receptor has been found in the follicles. In this study, the serotonin effect on preovulatory follicular steroidogenesis is investigated and the underlying mechanisms are elucidated. MATERIALS AND METHODS Female rats were subjected to SD for a time span of 1-4 days using the dish-over-water-method with a Rechtschaffen apparatus. Serum estradiol and serotonin concentrations were assessed; thereafter, they were evaluated with the effect of serotonin on the estradiol production and steroidogenic acute regulatory (StAR) protein expression in a serum-free culture system. Preovulatory follicles were dissected mechanically from the ovaries of 21-day-old rats, which induced follicle growth, and cultured for 24 hours with or without recombinant human follicle-stimulating hormone (FSH) in the presence or absence of serotonin. RESULTS SD, led to a significant decrease in serum estradiol concentrations, while serotonin concentrations were significantly elevated (all p < 0.05). Follicles were cultured with a constant dose of FSH (50 mIU/mL) and increasing doses of serotonin, estradiol production was reduced by 20%. The inhibitory effect of serotonin was concentration dependent. The addition of serotonin (0.1 μg/mL) decreased FSH-induced estradiol production and attenuated FSH-stimulated follicular StAR protein expression. The inhibitory effects of serotonin could be reduced by the serotonin receptor antagonist ketanserin. CONCLUSION These findings suggest that decreased serum estradiol concentrations in SD rats may be the result of serotonin-related inhibition of estradiol production and decreased large follicle expression of StAR protein.

Abstract
Various sedative agents, including dexmedetomidine (dex), induce immunosuppression, and enhance infection progression. However, there was no information on how anesthetic affects local and systemic cellular immune function. We conducted this study to examine the impact of dex on the differentiation and function of immune cells at site of inflammation and in peripheral blood during endotoxemia of mice. In BALB/c mice with and without endotoxemia, we evaluated the influence of two dosages of 5 and 50 mcg/kg/h intravenous dex on immune cells: including number of T cells (CD3), B cells (CD19), natural killer cells (CD8a), monocytes (CD11b), and macrophages (Mac-3) in peripheral blood, the activities of macrophages in peripheral blood and in peritoneal lavage, and proliferation of B and T cells and of natural killer cells activity in the spleen. Endotoxemia increased the number of CD3 T cells, CD 19 B cells and macrophages in the peripheral blood, augmented macrophage activity in the peritoneum, and increased T cell proliferation and natural killer cell activity in the spleen. Further administration of 5 mcg/kg/h dex attenuated systemic increase in number of T cells, B cells, and macrophages during endotoxemia and 50 mcg/kg/h dex significantly attenuated the increase in activity of macrophages in the peripheral blood during endotoxemia. In the peritoneum, however, 5 mcg/kg/h dex preserved and 50 mcg/kg/h dexmedetomidine enhanced the activity of macrophages during endotoxemia. Increased in proliferation of T cells in spleen during endotoxemia was attenuated by both doses of dex. Last, 50 mcg/kg/h dex enhanced natural killer cells activity during endotoxemia. While preserving the effects of endotoxemia on macrophage's activity in the infection site and natural killer cell's activity in the spleen, dex decreased systemic fulminant immune reaction in endotoxemia, by attenuating the augmented response in the number of T cells, B cells and macrophages, activity of macrophages in the peripheral blood, and proliferation of T cells in spleen during endotoxemia.

Abstract
Prostate cancer has its highest incidence and is becoming a major concern. Many studies have shown that traditional Chinese medicine exhibited antitumor responses. Quercetin, a natural polyphenolic compound, has been shown to induce apoptosis in many human cancer cell lines. Although numerous evidences show multiple possible signaling pathways of quercetin in apoptosis, there is no report to address the role of endoplasmic reticulum (ER) stress in quercetin-induced apoptosis in PC-3 cells. The purpose of this study was to investigate the effects of quercetin on the induction of the apoptotic pathway in human prostate cancer PC-3 cells. Cells were treated with quercetin for 24 and 48 h and at various doses (50-200 μM), and cell morphology and viability decreased significantly in dose-dependent manners. Flow cytometric assay indicated that quercetin at 150 μM caused G0/G1 phase arrest (31.4-49.7%) and sub-G1 phase cells (19.77%) for 36 h treatment and this effect is a time-dependent manner. Western blotting analysis indicated that quercetin induces the G0/G1 phase arrest via decreasing the levels of CDK2, cyclins E, and D proteins. Quercetin also stimulated the protein expression of ATF, GRP78, and GADD153 which is a hall marker of ER stress. Furthermore, PC-3 cells after incubation with quercetin for 48 h showed an apoptotic cell death and DNA damage which are confirmed by DAPI and Comet assays, leading to decrease the antiapoptotic Bcl-2 protein and level of ΔΨm , and increase the proapoptotic Bax protein and the activations of caspase-3, -8, and -9. Moreover, quercetin promoted the trafficking of AIF protein released from mitochondria to nuclei. These data suggest that quercetin may induce apoptosis by direct activation of caspase cascade through mitochondrial pathway and ER stress in PC-3 cells.

Abstract
Propofol is one of the most widely clinically used intravenous anesthetic, and it induces apoptosis in human and murine leukemia cell lines. Yet, whether propofol causes DNA damage and affects the mRNA expression of repair-associated genes in cancer cells remains undetermined. In the present study, we investigated the effects of propofol on DNA damage and associated mRNA gene expression in RAW264.7 cells. Comet assay and DNA gel electrophoresis were used to evaluate DNA damage in RAW264.7 cells and propofol-inhibited cell growth in vitro. The results revealed a longer DNA tail and DNA fragmentation. Real-time PCR assay was used to examine mRNA gene expression of DNA damage and DNA repair-associated genes. Following exposure to propofol for 48 h, a decrease in the mRNA expression of DNA-PK, BRCA1, MGMT and p53 was noted in the RAW264.7 cells. Results from the western blotting indicated that p53, MGMT, 14-3-3-σ, BRCA1 and MDC1 proteins were decreased while p-p53 and p-H2A.X(S140) were increased in the RAW264.7 cells following exposure to propofol. In conclusion, exposure to propofol caused DNA damage and inhibited mRNA expression and protein levels of repair-associated genes in RAW264.7 cells.

Abstract
Propofol (2,6-diisopropylphenol) is the most extensively used general anesthetic-sedative agent and it is employed in clinical patients. It has been shown that propofol exhibits anticancer activities. However, there is no available information to address propofol-induced cytotoxic effects and affected gene expressions on murine leukemia cells. Therefore, we investigated the effects of propofol on the levels of protein and gene expression, which are associated with apoptotic death in mouse leukemia RAW 264.7 cells in vitro. Results indicated that propofol induced cell morphological changes, cytotoxicity, and induction of apoptosis in RAW 264.7 cells in vitro. Western blot analysis demonstrated that propofol promoted Fas, cytochrome c, caspase-9 and -3 active form and Bax levels, but inhibited Bcl-xl protein level which led to cell apoptosis. Furthermore, cDNA microarray assay indicated that propofol significantly enhanced 5 gene expressions (Gm4884; Gm10883; Lce1c; Lrg1; and LOC100045878) and significantly suppressed 26 gene expressions (Gm10679; Zfp617; LOC621831; LOC621831; Gm5929; Snord116; Gm3994; LOC380994; Gm5592; LOC380994; Gm4638; LOC280487; Gm4638; Tex24; A530064D06Rik; BC094916; EG668725; Gm189; Hist2h3c2; Gm8020; Snord115; Gm3079; Olfr198; Tdh; Snord115; and Olfr1249). Based on these observations, propofol-altered apoptosis-related proteins might result from induction of apoptotic gene expression and inhibition of cell growth gene expression, which finally led to apoptosis in a mouse leukemia cell line (RAW 264.7) in vitro.

Abstract
Metastasis is a major cause of death of patients with malignant tumors. Matrix metalloproteinases (MMPs) are important for the migration and invasion of various types of cancer cell. Propofol is a known anesthetic agent, widely used for short-term anesthesia and for longer-term sedation. Propofol inhibits the proliferation of a variety of tumor cells, but there is no available information regarding propofol-inhibited migration and invasion of tumor cells in vitro. In this study, we investigated the effects of propofol on the migration and invasion of human lung carcinoma A549 cells. Wound healing assay and Boyden chamber assays indicated that propofol inhibited the migration and invasion of A549 cells in vitro. Gelatin zymographic analysis showed the inhibitory effect of propofol on the activation of expression MMP-2. Western blot analysis also indicated that propofol suppressed the protein expiration of growth factor receptor-bound protein 2 (GRB2), Jun N-terminal kinases 1/2 (p-JNK1/2), p-p38, MMP-2 and MMP-9 in A549 cells. Results from real-time PCR assay also showed that propofol inhibited the mRNA gene expression of MMP-2, -7 and -9, and enhanced that of tissue inhibitor of metalloproteinase 1 (TIMP1) and TIMP2 in A549 cells. Taken together, these data show that propofol inhibits MMP-2 and -9 mRNA and protein expressions, resulting in suppression of lung cancer cell invasion and migration in vitro.

Abstract
PURPOSE The edible mushroom (fungus) Agaricus blazei Murill (ABM) is a health food in many countries. Importantly, it has been shown to have antitumor and immune effects. There is no available information on ABM-affected immune responses in leukemia mice in vivo. Experimental Design. In this study, the authors investigated the immunopotentiating activities of boiled water-soluble extracts from desiccated ABM in WEHI-3 leukemia mice. The major characteristic of WEHI-3 leukemia mice are enlarged spleens and livers after intraperitoneal injection with murine leukemia WEHI-3 cells. Isolated T cells from spleens of ABM-treated mice resulted in increased T-cell proliferation compared with the untreated control with concanavalin A stimulation. RESULTS ABM decreased the spleen and liver weights when compared with WEHI-3 leukemia mice and this effect was a dose-dependent response. ABM promoted natural killer cell activity and phagocytosis by macrophage/monocytes in leukemia mice in a dose-dependent manner. ABM also enhanced cytokines such as interleukin (IL)-1β, IL-6, and interferon-γ levels but reduced the level of IL-4 in WEHI-3 leukemia mice. Moreover, ABM increased the levels of CD3 and CD19 but decreased the levels of Mac-3 and CD11b in leukemia mice. CONCLUSIONS The ABM extract is likely to stimulate immunocytes and regulate immune response in leukemia mice in vivo.

Abstract
Numerous studies have shown that rutin has anticancer effects. We have previously reported that rutin induced cell cycle arrest and apoptosis in murine leukemia WEHI-3 cells in vitro and in vivo. However, there are no data showing that rutin inhibits human leukemia HL-60 cells in vivo in a murine xenograft animal model. Human leukemia HL-60 cells were implanted into mice and treated with vehicle (1% DMSO), rutin (120 mg/kg of body weight) or vinblastine (120 μg/kg of body weight). Compounds and agents were injected once every four days intraperitoneally (i.p.) for 36 days. Treatment with 120 mg/kg of rutin or with 120 μg/kg of vinblastine resulted in a reduction of tumor weight and volume when compared with the control groups. Tumor size in xenograft mice treated with 120 mg/kg of rutin was significantly smaller than that in the untreated-control group. These novel findings indicate that rutin inhibits tumor growth in a xenograft animal model. Rutin may be useful in treating leukemia but certainly much more research is needed. © 2011 Wiley Periodicals, Inc. Environ Toxicol, 2012.

Abstract
We have shown that gypenosides (Gyp) induced cell cycle arrest and apoptosis in many human cancer cell lines. However, there are no reports showing that show Gyp acts on human leukemia HL-60 cells in vitro and in a murine xenograft model in vivo. In the present study effects of Gyp on cell morphological changes and viability, cell cycle arrest and induction of apoptosis in vitro and effects on Gyp in an in vivo murine xenograft model. Results indicated that Gyp induced morphological changes, decreased cell viability, induced G0/G1 arrest, DNA fragmentation and apoptosis (sub-G1 phase) in HL-60 cells. Gyp increased reactive oxygen species production and Ca(2+) levels but reduced mitochondrial membrane potential in a dose- and time-dependent manner. Gyp also changed one of the primary indicators of endoplasmic reticulum (ER) stress due to the promotion of ATF6-α and ATF4-α associated with Ca(2+) release. Gyp reduced the ratio of Bcl-2 to Bax due to an increase in the pro-apoptotic protein Bax and inhibited levels of the anti-apoptotic protein Bcl-2. Oral consumption of Gyp reduced tumor size of HL-60 cell xenograft mode mice in vivo. These results provide new information on understanding mechanisms by which Gyp induces cell cycle arrest and apoptosis in vitro and in vivo.

Abstract
Etomidate is an important tool in the arsenal of the emergency physician, and it has been used in a variety of scenarios for both intubation and procedural sedation. In the present study, we investigated the cytotoxicity of etomidate including induction of apoptosis, and levels of protein and gene expressions associated with apoptotic cell death in murine leukemia RAW264.7 cells in vitro. Cytotoxic and apoptotic responses to etomidate of RAW264.7 cells, including cell morphological changes and cell viability were examined and measured by phase-contrast microscopy and flow cytometric assay, respectively. Results indicated that etomidate increased apoptotic cell morphological changes and reduced cell viability in RAW264.7 cells. 4',6-Diamidino-2-phenylindole (DAPI) staining also showed that etomidate induced the formation of apoptotic bodies, a characteristic of apoptosis. Results from Western blotting indicated that etomidate enhanced the levels of cytochrome c, apoptosis-inducing factor (AIF), endonuclease G (Endo G), caspase-9, caspase-3 active form and Bax proteins, but it inhibited the expression of Bcl-xl, leading to apoptosis. DNA microarray assay indicated that etomidate increased the expression of 17 genes (LOC676175; Gm14636; 2810021G02Rik; Iltifb; Olfr1167; Ttc30b; Olfr766; Gas5; Rgs1; LOC280487; V1rd4; Hist1h2bc; V1rj3; Gm10366; Olfr192; Gm10002 and Cspp1) and reduced the expression of 15 genes: (Gm10152; Gm5334; Olfr216; Lcn9; Gm10683; Gm5100; Tdgf1; Cypt2; Gm5595; 1700018F24Rik; Gm10417; Maml2; Olfr591; Trdn and Apol7c). In conclusion, etomidate induced cytotoxic and apoptotic effects the in murine leukemia RAW264.7 cells in vitro.

Abstract
Antrodia cinnamomea is an expensive and highly valued folk medicinal fungus that grows only inside the rotten trunk of Cinnamomum kanehirae, an evergreen broad-leaved tree. This fungus has recently been used commercially in the formulation of nutraceuticals and functional foods in Taiwan. It has been used for centuries as a detoxificant in cases of food poisoning, diarrhea, vomiting, hepatic disease and various kinds of cancers. The present study investigated the effects of Antrodia cinnamomea on mutagenicity using a bacterial reverse mutation assay employing the Salmonella typhimurium strains TA97, TA98, TA100, TA102, and TA1535. The effects of Antrodia cinnamomea on chromosome structure were tested in Chinese hamster ovary (CHO) cells. Antrodia cinnamomea was not mutagenic in all bacterial strains and it was not genotoxic in CHO cells.

Abstract
In Taiwan, oral cancer is the fourth leading cause of male cancer mortality, and is still increasing. The Basiodiomycete, Agaricus brasiliensis Murill (ABM) is a dietary mushroom and has been known for its immuneenhancing, antitumor, antioxidation, antiviral and antimutagenesis functions. However, the exact anticancer mechanisms of ABM on human oral cancer cells are still unclear. In the present study, we investigated the effects of 50% ethanol crude extracts and hot water extracts of ABM on oral cancer CAL 27 cells. We observed that 0.9 mg/ml and 0.7 mg/ml of ABM 50% ethanol crude extracts and hot water, respectively, caused morphological changes and significantly reduced cell viability after 48-h treatment. The results showed that both extracts of ABM inhibited cell proliferation, increased the Ca(2+) release, reduced the mitochondria membrane potential (ΔΨm), and caused cell cycle arrest in the G(0)/G(1) phase, which contributed to apoptosis. Additionally, ABM induced DNA fragmentation, a characteristic of apoptosis and the expressions of apoptosis-related proteins, including apoptosis-inducing factor, cytochrome c, and caspase-3, were increased. Overall, we demonstrated that 50% ethanol crude extract and hot water extracts of ABM were able to induce apoptotic cell death in CAL 27 cells via the release of cytochrome c from mitochondria into the cytoplasm and activation of caspase-3 in vitro.

Abstract
Diallyl sulfide (DAS), one of the main active constituents of garlic, causes growth inhibition of cancer cells in vitro and promotes immune responses in vivo in experimental settings. However, its effects on the induction of cell cycle and apoptosis in human cervical cancer cells are still unclear. The aims of this study were to explore the anti-cancer effects of DAS in HeLa human cervical cancer cells and to investigate the underlying mechanisms in vitro. Cytotoxicity and apoptosis in HeLa human cervical cancer cells were examined by the morphological changes, viability assay, 4',6-Diamidino-2-phenylindole dihydrochloride (DAPI) staining, comet assay, Western blotting and confocal microscopy examination. The results showed that DAS treatment for 24-72 h resulted in a marked decrease in cell viability time- and dose-dependently. Flow cytometric analysis showed that a 48-h treatment of 75 µM DAS induced G0/G1 cell cycle arrest and sub-G1 phase (apoptosis) in HeLa cells. Typical apoptotic nucleus alterations were observed by fluorescence microscopy in HeLa cells after exposure to DAS using DAPI staining. Cells treated with different concentrations of DAS also showed changes typical of apoptosis such as morphological changes, DNA damage and fragmentation, dysfunction of mitochondria, cytochrome c release and increased expression of pro-caspase-3 and -9. DAS also promoted the release of AIF and Endo G from mitochondria in HeLa cells. In conclusion, DAS induced G0/G1 cell cycle arrest and apoptosis in HeLa cells through caspase- and mitochondria and p53 pathways providing further understanding of the molecular mechanisms of DAS action in cervical cancer. This study, therefore, revealed that DAS significantly inhibits the growth and induces apoptosis of human cervical cancer HeLa cells in vitro.

Abstract
We report a 27-year-old hemostatically competent female scheduled for partial hepatectomy. During the operation, she experienced an accidental inferior vena cava tear and suffered acute blood loss. After fluid resuscitation and blood transfusion, she developed hypothermia, with a temperature of 33.8 degrees C, and severe coagulopathy with activated clotting time exceeding 1500 seconds measured using the Hemochron Response system (ITC, Edison, NJ, USA). Despite sufficient blood transfusion and correction of her electrolyte imbalance, the poor hemostasis persisted. After per-forming peritoneal lavage with warm saline, her condition dramatically improved and her hypothermia and severe coagulopathy were reversed.

Abstract
Dizziness and nausea are frequent problems among patients receiving patient-controlled epidural analgesia (PCEA) after major surgery. It is important to consider the various etiologies that might cause these adverse events, especially among patients who have undergone massive hepatic resection for living donor liver transplantation (LDLT). We have described 2 LDLT cases with persistent dizziness and nausea postoperatively despite several adjustments in PCEA management. Their symptoms were quickly relieved after suspension of PCEA medication. Our 2 cases of LDLT represented a unique setting for this type of complication.

Abstract
Tetramethylpyrazine (TMP) is the major component extracted from the Chinese herb, Chuanxiong, which is widely used in China for the treatment of cardiovascular problems. The aims of this study were to examine whether TMP may alter angiotenisn II (Ang II)-induced proliferation and to identify the putative underlying signaling pathways in rat aortic smooth muscle cells. Cultured rat aortic smooth muscle cells were preincubated with TMP and then stimulated with Ang II, [3H]-thymidine incorporation and the ET-1 expression was examined. Ang II increased DNA synthesis which was inhibited by TMP (1-100 microM). TMP inhibited the Ang II-induced ET-1 mRNA levels and ET-1 secretion. TMP also inhibited Ang II-increased NAD(P)H oxidase activity, intracellular reactive oxygen species (ROS) levels, and the ERK phosphorylation. Furthermore, TMP and antioxidants such as Trolox and diphenylene iodonium decreased Ang II-induced ERK phosphorylation, and activator protein-1 reporter activity. In summary, we demonstrate for the first time that TMP inhibits Ang II-induced proliferation and ET-1, partially by interfering with the ERK pathway via attenuation of Ang II-increased NAD(P)H oxidase and ROS generation. Thus, this study delivers important new insight in the molecular pathways that may contribute to the proposed beneficial effects of TMP in cardiovascular disease.

Abstract
The in vitro effect of extracted fractions of Cordyceps sinensis (CS) mycelium on hCG-treated testosterone production from purified normal mouse Leydig cells was examined. Different fractions extracted from CS (F1-water soluble polysaccharide, F2- water soluble protein and F3- poorly water soluble polysaccharide, and protein) were added to Leydig cells with hCG, and the production of testosterone was determined by radioimmunoassay (RIA). Testosterone productions stimulated by hCG in mouse Leydig cells were suppressed by F2 at 10 mg/ml and F3 at doses from 3 to 10 mg/ml, respectively. F2 and F3 at 10 mg/ml did inhibit dbcAMP-stimulated testosterone productions which indicated that F2 and F3 might affect steroidogenesis at the site after the formation of cyclic AMP. Finally, cycloheximide inhibited F2- and F3-treated mouse Leydig cell testosterone production.

Abstract
Syndrome of inappropriate secretion of antidiuretic hormone and diabetes insipidus occurring in very short order in the same patient is rare. We report a 9 month-old male infant suffering form holoprosencephaly developed syndrome of inappropriate secretion of antidiuretic hormone followed by diabetes insipidus within a relative short time postoperatively after his third operation. Inability to suppress as well as to stimulate arginine vasopressin secretion and anesthetic and surgical stresses, were thought to be the possible causes of this event.

Abstract
A 26-year-old pregnant woman with a body mass index of 60 was scheduled for cesarean section at 36 weeks' gestation. She was found having affected with gestational diabetes mellitus and hypertension at 17 weeks of pregnancy. The blood glucose level as controlled by subcutaneous injection of insulin was maintained at the level of 110-140 mg/dL. Hypertension was also controlled by methyldopa and hydralazine with the systolic pressure maintaining at 140-180 mmHg during the pregnancy. Abnormal perfusion of umbilical artery without compromise of placental function was found twice by Doppler prenatal examination at gestation of 33 and 34 weeks respectively. The operation was performed under general anesthesia. However, apnea and low Apgar score of the neonate were noted. General anesthesia was thought as the root cause of this event at first. After a series of examination and management, hypoglycemia and uteroplacental perfusion insufficiency were considered as the causes of this morbidity. The neonate's condition was improved in 48 hr after close care.

Abstract
Unintentional dural puncture is the most frequent cause of postdural puncture headache (PDPH) in epidural anesthesia and analgesia. Conservative treatments of PDPH include bed rest, oral analgesics, and hydration. When conservative measures fail, epidural blood patch is an effective substitute. However, epidural blood patch carries some risks, such as subdural hematoma, pneumocephalus, exacerbation of PDPH and new dural puncture. Many patients may refuse the procedure due to the risks involved. We describe a female patient who had her PDPH successfully treated with epidural saline delivered by a patient-controlled analgesia device (Abbott Pain Management-APM) without molestation of her daily activities.

Abstract
We report a case of generalized convulsion during partial hepatectomy for the purpose of organ donation for syngenesioplastic liver transplantation under sevoflurane anesthesia. This 23-year-old male Taiwanese living donor had no history of epilepsy. Anesthesia was inducted with fentanyl, propofol and rocuronium was used to facilitate endotracheal intubation. Sevoflurane in the mixture of oxygen and air and rocuronium were used for maintenance of anesthesia. Generalized convulsion with mild fever was observed 11 hours after the start of surgery when the surgeons happened to take a recess pending the removal of the recipient's liver. Convulsive episode subsided after aggressive management. Another 3 hours were required to complete the operation and the patient woke up in the postanesthesia room uneventfully.

Abstract
The so-called Dyke-Davidoff-Masson syndrome (DDMS) is a rare disorder of cerebral hemiatrophy. The clinical presentation may consist of facial asymmetry, contralateral atrophy (including the trunk, and the extremities) and hemiparesis, speech difficulties, mental retardation, and epilepsy. Because it involves multiple systems, especially problem of the airway, occult myopathy, and seizure disorder, anesthesia for such a patient is a challenge to any anesthesiologist. However, there are no clinical reports which concern the anesthetic management of such patients in the literature. We herein report a 5-year-old girl, a sufferer of DDMS, scheduled for burr trephination. The successful anesthetic management is brought forward with highlights of inference from the experience.

Abstract
The decrease of arterial blood pressure and body temperature after epidural or spinal anesthesia is thought to be the result of sympathetic block, which could cause pooling and redistribution of blood into the lower extremities. Studies have demonstrated that leg wrapping with elastic bandages may reduce the incidence of hypotension after spinal anesthesia. We tried to extend these previous observations to epidural anesthesia by testing the hypothesis that leg wrapping with elastic bandages should decrease the incidence of hypotension in patients receiving epidural anesthesia. Moreover, we evaluated the effect of this maneuver as regards hypothermia and shivering. Sixty parturients were randomly allocated to receive either leg wrapping with tight elastic bandages (leg-wrapped group) or not (control group) before anesthesia. Sublingual temperature was observed at five periods: baseline, immediately after epidural anesthesia, abdominal skin disinfection, skin incision, and delivery. Hypotension and shivering during the observation periods were also recorded. The incidence of hypotension was significantly less frequent (P = 0.03) in the leg-wrapped group (23%) compared with the control group (50%). Shivering incidences were similar in both groups (70% versus 70%). Sublingual temperature decreased significantly (P < 0.001) throughout the procedure in each group. However, no differences were found between the two groups at each designated observation, even if compared by the magnitude of temperature decrease. We conclude that although leg wrapping with elastic bandages prevents maternal hypotension after epidural anesthesia, it does not reduce the incidence or magnitude of hypothermia or prevent shivering.

Abstract
The purpose of this study was to investigate the antioxidant effects of a hot water extract of Panax notoginseng (PNG) against chronic ethanol-induced hepatotoxicity. Fifty mice were divided into fi ve equal groups with 10 in each group. Group 1 (control) received saline, whereas group 2 received ethanol (70%, 0.1 mL, p.o.) once daily for 4 weeks, which induced hepatotoxicity, manifested biochemically by a significant elevation of serum enzyme activities, such as SGOT and SGPT. Hepatotoxicity was further evidenced by a significant increase in the hepatic lipid peroxidation measured. Groups 3-5 were administered a hot water extract of PNG at doses of 10, 25 and 50 mg/kg 2 weeks after initiating oral administration of ethanol, for a further 2 weeks. PNG ameliorated the rise in serum sGOT and sGPT induced by chronic ethanol administration. The mice were killed after PNG administration. In a separate study, PNG inhibited the lipid peroxidation in the mouse liver homogenate induced by ethanol in a dose-dependent manner. The findings indicate that PNG is an efficient cytoprotective agent against chronic ethanol-induced hepatotoxicity, possibly through inhibition of the production of oxygen-free radicals that cause lipid peroxidation.

Abstract
BACKGROUND The risk of cardiac patients undergoing noncardiac surgery is relatively high. Successful preoperative evaluation and perioperative anesthetic management of a patient require a good communication among the patient, the anesthesiologist and the surgeon as well as excellent cooperation between the surgeon and anesthesiologist with a tacit understanding of the peri-operative risks. Peri-operative risk factors have been readily investigated in Caucasians or Westerners. As different ethnic populations may have different risk factors for a same disease entity, understanding the uniqueness in this respect in Taiwanese is mandatory. The purpose of this study is to examine the risk factors, perioperative cardiac events and the qualities of preoperative preparation and post-operative intensive care in Taiwanese cardiac patients undergoing noncardiac surgery. METHODS Two medical centers in Taiwan worked out a set of prospective questionnaire to evaluate the preoperative preparation, intraoperative events, and postoperative care of cardiac patients undergoing noncardiac surgery in these hospitals. RESULTS Between March 2002 and May 2002, there were 196 cardiac patients undergoing noncardiac surgery out of a total of 10,129 anesthetized surgical patients in two medical centers. The risk factors of these patients included coronary artery disease, hypertension, diabetes mellitus, congestive heart failure, arrhythmia, and renal function impairment. In these 196 cases, only 26.5% (52) and 16.8% (33) had been preoperatively evaluated by cardiologist and anesthesiologist respectively through consultation. The number of pre-operation specific cardiac tests totaled 34, and 41 patients (20.9%) required post-operative intensive care. There were two peri-operative fatalities and fourteen peri-operative cardiac events. CONCLUSIONS The quality of care for preoperative evaluation and quality assurance need to be improved in Taiwan.

Abstract
Many volatile anesthetics have long been thought to affect pulmonary functions including lung ventilation (LV) and alveolar epithelial permeability (AEP). The purpose of this study is to examine the influence of volatile anesthetics on LV and AEP by noninvasive radionuclide lung imaging of technetium-99m labeled diethylene triamine pentaacetic acid radioaerosol inhalation lung scan (DTPA lung scan). Twenty patients undergoing surgery and receiving volatile anesthesia with 1% halothane were enrolled as the study group 1. The other 20 patients undergoing surgery and receiving volatile anesthesia with 1.5% isoflurane were enrolled as the study group 2. At the same time, 20 patients undergoing surgery with intravenous anesthesia drugs were included as a control group. Before surgery, 1 hour after surgery, and 1 week after surgery, we investigated the 3 groups of patients with DTPA lung scan to evaluate LV and AEP by 99mTc DTPA clearance halftime (T1/2). No significant change or abnormality of LV before surgery, 1 hour after surgery, or 1 week after surgery was found among the 3 groups of patients. In the control group, the 99mTc DTPA clearance T1/2 was 63.5 +/- 16.4, 63.1 +/- 18.4, and 62.8 +/- 17.0 minutes, before surgery, 1 hour after surgery, and 1 week after surgery, respectively. In group 1, it was 65.9 +/- 9.3, 62.5 +/- 9.1, and 65.8 +/- 10.3 minutes, respectively. No significant change in AEP before surgery, 1 hour after surgery, or 1 week after surgery was found. However, in group 2, the 99mTc DTPA clearance T1/2 was 65.5 +/- 13.2, 44.9 +/- 10.5, and 66.1 +/- 14.0 minutes, respectively. A significant transient change in AEP was found 1 hour after surgery, but it recovered 1 week after surgery. We conclude that volatile anesthesia is safe for LV and AEP, and only isoflurane can induce transient change of AEP.
