RESUMO

BACKGROUND: Alpinia nantoensis (Zingiberaceae) is an aromatic plant endemic to Taiwan, which is used as food flavoring and traditional herbal medicine. The biological activities of compounds isolated from this plant are rarely investigated. PURPOSE: The present study was aimed to investigate the anti-metastatic potential of trans-3­methoxy­5-hydroxystilbene (MHS) a major stilbene isolated from the rhizomes of A. nantonensis. METHODS: We investigated the anti-metastatic potential of MHS on human non-small cell lung carcinoma (A549) cell line using wound healing, trans-well, western blot, zymography and immunofluorescence assays. RESULTS: Initial cytotoxicity assay showed that treatment with MHS did not exhibit cytotoxicity to A549 cells up to the concentration of 40 µM. Further in vitro wound healing and transwell chamber assays revealed that MHS significantly inhibited tumor cell migration in a dose-dependent manner, which is associated with inhibition of matrix mettalloprotinase-2 (MMP-2) and matrix mettalloprotinase-9 (MMP-9) at both enzyme and protein levels. The inhibition of MMPs activity by MHS was reasoned by suppression of their corresponding transcription factor, ß-catenin as indicated by reduced levels of ß-catenin in the nucleus. MHS also regulates epithelial-to-mesenchymal transition (EMT) by increasing E-cadherin and occludin as well as decreasing N-cadherin levels in A549 cells. Furthermore, pre-treatment with MHS significantly inhibited A549 cells migration and EMT in TGF-ß induced A549 cells. CONCLUSION: To the best of our knowledge, this is the first report demonstrating that MHS, a plant-derived stilbene has a promising ability to inhibit lung cancer cell metastasis in vitro.

RESUMO

Urban soil is an important part of the urban ecosystem, which is strongly correlated with human health and life quality. In this study, Lin'an city was chosen as a typical small city to study the spatial variation and distribution of heavy metals in urban soils and their pollution characteristics using multivariate analysis, geostatistics, and GIS techniques. A total of 62 soil samples were collected from the study areas. The results indicated that the average concentrations of soil Mn, Cu, Zn, Pb, Cr, and Cd were 439.42, 42.23, 196.80, 62.55, 63.65, and 0.22 mg·kg-1, respectively. Compared with the background values and the environmental quality standards, these heavy metals were accumulated in urban soils to some extent. Almost 80% of the study area was polluted by heavy metals. The single potential ecological risk index of heavy metals indicated that Pb had the highest ecological risk. The pH and most of the heavy metals had strong correlations, and there were strong correlations among the heavy metals. The principle component analysis (PCA) showed that Pb, Zn, and Cu had the same pollution source, which was related to vehicle exhausts; Mn and Cr were mainly from the parent material; and Cd was from the emissions of manufacturing plants. The spatial structure and distribution of heavy metals and their corresponding available fractions had strong spatial autocorrelation with all of the C0/(C0+C)<50%. Their spatial patterns were influenced by human activities.

RESUMO

Pain afflflicts over 50 million people in the US, with 30.7% US adults suffering with chronic pain. Despite advances in therapies, many patients will continue to deal with ongoing symptoms that are not fully addressed by the best conventional medicine has to offer them. The patients frequently turn to therapies outside the usual purview of conventional medicine (herbs, acupuncture, meditation, etc.) called complementary and alternative medicine (CAM). Academic and governmental groups are also starting to incorporate CAM recommendations into chronic pain management strategies. Thus, for any physician who care for patients with chronic pain, having some familiarity with these therapies-including risks and benefits-will be key to helping guide patients in making evidence-based, well informed decisions about whether or not to use such therapies. On the other hand, if a CAM therapy has evidence of both safety and efficacy then not making it available to a patient who is suffering does not meet the need of the patient. We summarize the current evidence of a wide variety of CAM modalities that have potential for helping patients with chronic pain in this article. The triad of chronic pain symptoms, ready access to information on the internet, and growing patient empowerment suggest that CAM therapies will remain a consistent part of the healthcare of patients dealing with chronic pain.

RESUMO

OBJECTIVE: To assess the clinical efficacy of danlou tablet (DT) in treating coronary heart disease angina (CHDA) patients of phlegm and stasis mutual obstruction syndrome (PSMOS). METHODS: Totally 66 CHDA patients of PSMOS were recruited from four centers (Beijing Guang'anmen Hospital, Beijing Anzhen Hospital, First Affiliated Hospital of Henan College of Traditional Chinese Medicine, and Hubei Union Hospital). They were assigned to two groups according to the random digit table, the treatment group (treated by DT +Western medicine) and the control group (treated by Western medicine), 33 in each group. All patients took Western medicine. Patients in the treatment group were given DT, 1.5 g each time, twice daily, while those in the control group took DT placebo. The treatment course was 28 days for all. The efficacy of angina, the angina attack frequency, its duration, the score of angina, the numbers of ST segment depression and flat or inversed T wave, the lead number of inversed T wave, the angina relief time after taking nitroglycerin, the amount of nitroglycerin were observed in the two groups. The changes of Chinese medicine (CM) syndrome scores, including the duration and frequency of chest tightness and pain, shortness of breath, fatigue, palpitation, spontaneous sweating, and total syndrome score were compared before and after treatment. The changes of hypersensitive C-reactive protein (hs-CRP), homocysteic acid (HCY), soluble CD40 ligand (sCD40L), interleukin-6 (IL-6), myeloperoxidase (MPO), matrix metalloproteinase-9 (MMP-9), and vascular cell adhesion molecular-1 (VCAM-1) were also observed in both groups. RESULTS: The total effective rate was significantly higher in the treatment group (26/32 cases, 81.2%) when compared with the control group (13/30 cases, 43.3%, P < 0.05). Compared with before treatment in the same group, the duration and frequency of chest tightness and pain, the score of angina, the numbers of ST segment depression and flat or inversed T wave, the lead number of inversed T wave, the angina relief time after taking nitroglycerin, the amount of nitroglycerin, the duration and frequency of chest tightness and pain, hs-CRP, sCD40L, HCY, IL-6, MMP-9, MPO were lowered after treatment in both groups (P < 0.01, P < 0.05). The VCAM-1 level decreased in the treatment group, while it increased in the control group, showing statistical difference (P < 0.01, P < 0.05). Compared with the control group after treatment, the duration and frequency of chest tightness and pain, the score of angina, the angina relief time after taking nitroglycerin, the amount of nitroglycerin, the duration and frequency of chest tightness and pain, fatigue, the total syndrome score, the levels of hs-CRP, sCD40L, HCY, IL-6, MMP-9, MPO, and VCAM-1 were lowered in the treatment group after treatment (P < 0.01, P < 0.05). CONCLUSION: DT could improve CHDA patients' clinical symptoms, inhibit the inflammation reaction, showing plaque stabilizing and anti-oxidization effects.

RESUMO

BACKGROUND: With the wide application of percutaneous coronary intervention (PCI) in patients with coronary heart disease (CHD), it is a popularly concerned problem within clinical doctors to promote the patients' early recovery and improve their health related quality of life (HR-QoL). OBJECTIVE: To evaluate the efficacy and safety of Xuefu Zhuyu (XFZY) Capsule, a compound traditional Chinese herbal medicine for activating blood circulation, in improving HR-QoL in unstable angina (UA) patients with blood-stasis syndrome after PCI, and to make a comparison with Shengmai (SM) Capsule. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: The study was performed at Rescue Center of Emergency, Beijing Anzhen Hospital, China Capital University of Medical Science from March 2008 to February 2009. Using a randomized, double-blinded, double-dummy and placebo controlled study design, ninety patients diagnosed as UA and concomitant blood stasis syndrome after successful PCI therapy were enrolled and randomized into three groups: XFZY group, SM group and placebo group, and the patients were administered with the corresponding medications for 4 weeks. MAIN OUTCOME MEASURES: The Short-Form 36 (SF-36) and Seattle Angina Questionnaire (SAQ) were applied to assess the HR-QoL in each group before and after the treatment. RESULTS: A total of 90 patients were recruited and 4 cases of them withdrew from the study during the treatment period indicating a 4.4% of dropping rate. After the treatment, several domains of scores in SF-36 and SAQ were significantly increased in three groups (P<0.05, P<0.01). The efficacy of XFZY Capsule in improving body pain (BP), general health (GH), vitality (VT), social function (SF), role emotional (RE), angina stability (AS), angina frequency (AF), as well as treatment satisfaction (TS) was better than that of placebo (P<0.05, P<0.01). Meanwhile, the dimensions of BP, GH, SF, AS, AF, TS were improved as compared with those in the SM group (P<0.05). No obvious adverse reaction was found during and after the treatment with the exception of one case in XFZY group reporting of discomfort in the stomach. CONCLUSION: Compared with SM Capsule, a short-term treatment of XFZY Capsule exhibits better efficacy in improving HR-QoL in UA patients with blood-stasis syndrome after PCI. However, its long-term efficacy and safety needs further investigation. TRIAL REGISTRATION: ClinicalTrials.gov Identifier, NCT00817024.
