OBJECTIVETo explore the correlation between signs of living body in abdominal and pelvic cavities and syndrome typing of Chinese medicine (CM) in colorectal cancer patients.

METHODSTotally 112 colorectal cancer patients undergoing open abdominal surgery or laporoscopic surgery were syndrome typed as five types, i.e., inner-accumulation of damp and heat, blockage of stasis and toxin, Pi-Shen yang deficiency, blood-qi deficiency, Gan-Shen yin deficiency. Signs of living body in abdominal and pelvic cavities were collected. The correlation between signs of living body in abdominal and pelvic cavities and syndrome typing of CM were analyzed.

RESULTSRed colorectal canals or mass were dominated in colorectal cancer patients with inner-accumulation of damp and heat syndrome. Dark purple colorectal canals or mass were dominated in colorectal cancer patients with blockage of stasis and toxin syndrome. Reddish colorectal canals or mass were dominated in colorectal cancer patients with blood-qi deficiency syndrome. Pale colorectal canals or mass were dominated in colorectal cancer patients with Pi-Shen yang deficiency syndrome. Whitish or red-white stripes were dominated in colorectal cancer patients with Gan-Shen yin deficiency syndrome. Dropsy colorectal canal was associated with Pi-Shen yang deficiency syndrome. Intracavitary effusion was often seen in colorectal cancer patients with inner-accumulation of damp and heat syndrome. The effusion was yellowish in less amount. Intracavitary adhesion was often seen in colorectal cancer patients with blockage of stasis and toxin syndrome. There was no correlation between the maximum diameter of mass or each syndrome type of CM.

CONCLUSIONThere existed correlation between signs of living body in abdominal and pelvic cavities and syndrome typing of CM, which could be taken as one of references for syndrome typing of colorectal cancer patients.

OBJECTIVETo investigate the protective effects of adiponectin on myocardial ischemia-reperfusion injury and the potential mechanisms in rats.

METHODSThirty-two male rats aged 8 weeks were randomly assigned to sham operation (sham), myocardial ischemia-reperfusion (MIR), diltiazem treatment (diltiazem) or adiponectin administration (APN) groups (n = 8 each). MIR rats underwent left anterior descending artery (LAD) occlusion for 30 min followed by 60 min reperfusion. Diltiazem (7 microg/g) and APN (120 ng/g) were given by caudal intravenous injection at the end of 30 min ischemia and the beginning of reperfusion for rats in diltiazem or APN groups. Animals were sacrificed after 60 min reperfusion for determining the myocardial nitric oxide (NO), Caspase 3, activity of AMP-activated protein kinase(AMPK) and concentration of peroxisome proliferators-activated receptor gamma (PPARgamma). Apoptotic cells were stained by Caspase 3 Activity Assay Kit and mitochondria in myocardial cells were observed by transmission electron microscope (TEM).

RESULTSThe myocardial Caspase 3 level was significantly increased [(168.50 +/- 30.08) micromol/L vs. (53.25 +/- 11.41) micromol/L, P < 0.01], AMPK activity, PPARgamma and NO concentrations were significantly reduced in MIR group compared with those in sham group (all P < 0.05) [(0.74 +/- 0.59) IU/ml vs. (25.63 +/- 4.61) IU/ml, P < 0.01; 0.1894 vs. 0.7949, P < 0.01; (6.359 +/- 1.355) micromol/L vs. (10.396 +/- 1.901) micromol/L, P < 0.01], these effects could be significantly reversed by APN. In comparison with MIR group, the levels of Caspase 3 in cardiac muscles were significantly lowered in Adiponectin group [(88.75 +/- 6.92) micromol/L vs. (168.50 +/- 30.08) micromol/L, P < 0.01], whereas the level of AMPK and PPARgamma, NO concentration in the cardiac muscle was remarkably increased [(27.22 +/- 4.76) IU/ml vs. (0.74 +/- 0.59) IU/ml, P < 0.01; 0.8613 vs. 0.1894, P < 0.01; (15.755 +/- 1.045) micromol/L vs. (6.359 +/- 1.355) micromol/L, P < 0.01]. APN also preserved the function and structure of mitochondria in rats post ischemia/reperfusion injury. The protective pharmacologic actions of APN were superior to that of diltiazem.

CONCLUSIONAdiponectin could protect myocardial tissues from myocardial ischemia-reperfusion injury in rats, possibly by upregulating myocardial AMPK and PPARgamma expressions and preventing myocardial cells from apoptosis.

To study the anti-coagulant effect and influence of danggui Sini decoction (DSD) on rat's plasma endogenous metabolites by animal experiment and ¹H-NMR based metabolomics method. After intragastric administration of Danggui Sini Decoction for 7 days, Plasma thrombin time (TT) was measured. Rat plasma metabolic fingerprint in two groups was analyzed using ¹H-NMR, based on which the principal component analysis( PCA) and orthogonal partial least-squares discriminant analysis(OPLS-DA) models for metabonomic analysis. Potential biomarkers were screened by using variable importance in the projection (VIP) and T test. DSD could prolong TT of the rat significantly (P < 0.05). Compared with control group, six kinds of endogenous metabolites in DSD group change significantly (P < 0.05), among which isobutyrate, carnitine and phenylalanine content had an upward trend (P < 0.01) and lysine, Histidine and cholesterol content had a downward trend (P < 0.05). It is likely that carnitine, phenylalanine, Histidine and cholesterol are the potential metabolic markers in the anti-coagulant process and DSD affects the platelet aggregation and the expression of tissue factor and fiber protease by regulating the energy, amino acid and lipid metabolism.

OBJECTIVETo study the epidemiologic characteristics of hand-foot-mouth disease (HFMD) in Guiyang between 2008 and 2010.

METHODSThe epidemiologic characteristics of HFMD were analyzed by descriptive statistical methods based on the data from the China Information System for Disease Control and Prevention.

RESULTSA total of 27383 cases of HFMD were recorded in Guiyang between 2008 and 2010. The incidence of HFMD increased from 66.4439/100000 in 2008 to 163.9276/100000 in 2009 and 471.5515/100000 in 2010 (P<0.01). The mortality rate was 0.1026/100000 in 2010, which was significantly lower than in 2009 (0.2821/100000) (P<0.05). HFMD occurrence showed seasonality and reached a peak between April and June. HFMD cases were commonly noted in children under 5 years old, and especially in children under 3 years old. The main detected pathogen was human enterovirus 71 (EV17) in 2009. Whereas in 2010 the disease was mainly caused by CoxA16 and other intestinal viruses.

CONCLUSIONSThe incidence of HFMD in Guiyang increased year by year from 2008 to 2010, but the mortality rate decreased year by year. HFMD occurrence showed an obvious seasonality. HFMD was common in children under the age of five. The main pathogens of this disease included EV17, CoxA16 and other intestinal viruses.

BACKGROUNDThe prognosis of unresectable large hepatocellular carcinomas is poor. This study evaluated the efficacy and safety of sorafenib combined with transcatheter arterial chemoembolization and radiofrequency ablation in the treatment of hepatocellular carcinomas larger than 5 cm.

METHODSThe treatment of 22 patients with large, unresectable hepatocellular carcinomas (5.0-16.5 cm) treated with sorafenib after transcatheter arterial chemoembolization combined with radiofrequency ablation between 2007 and 2011 was reviewed. The local effects, survival rates, toxicity, and prognostic factors were analyzed.

RESULTSDuring a follow-up of 9-49 months, 19 patients died and three survived. The median overall survival was 32 months. The overall cumulative 12, 24, and 36-month survival rates were 85.9%, 66.8%, and 23.5% respectively. Technical effectiveness was achieved in 12 out of 28 lesions (42.85%) at the first CT check. The median time to tumor progression was 21 months. The progression-free survival rates at 6, 12, and 24 months were 90.9%, 72.0%, and 38.4%, respectively. Combined therapy was generally well tolerated. There was only one major procedure-related complication, biloma (4.5%). Sorafenib-related adverse events exceeding grade 3 were hand-foot skin reaction (2/22, 9.1%), gastrointestinal hemorrhage (1/22, 4.5%), and diarrhea (2/22, 9.1%). The absence of vascular invasion before treatment was found to be the best prognostic factor in the univariate analysis.

CONCLUSIONSSorafenib combined with transcatheter arterial chemoembolization and radiofrequency ablation is a promising approach to the treatment of large, unresectable hepatocellular carcinomas. However, large-scale randomized clinical trials are needed to determine the future role of this treatment.

Ex vivo expansion of hematopoietic progenitor cells (HPCs) is valuable for clinical application, however, traditional ex vivo culture negatively affects long-term hematopoietic reconstitution ability. In the hematopoietic system, the expression of Notch receptors and their ligands has been widely reported. Active Notch signal inhibits the differentiation of HSCs while promotes their expansion, suggesting that ex vivo expansion of hematopoietic progenitor cells could be enhanced by manipulating Notch signal pathways. In this article the Notch signal pathways, Notch signal and maintenance of hematopoietic progenitor cells, Notch signal and expansion of hematopoietic progenitor cells and molecular mechanism of Notch signal maintaining undifferentiation of hematopoietic progenitor cells were reviewed.
