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.

The Telomeric Repeat Amplification Protocol(TRAP)and its modified versions change the size and/or the ratio of the telomerase products in the amplification stage of the assay.Based on TRAP,a useful method was developed for detecting telomerase activity in rice.A special precursor primer and a special reverse primer and conducted two steps of PCR cycles were designed.GENE Genius? Bio-imaging System was applied for this quantitative analysis for exploring telomerase activity and its optimal reaction conditions.The method ensured that the optimal reaction conditions for the telomerase was 19℃,13minutes,at a concentration of 0.28 u g/? l.A quantitative analysis method was established for detecting telomerase activity in rice.With this method,we detected telomerase activity in roots,young leaves and young panicles of six parental lines of hybrid rice.The results show that young panicles have the highest telomerase activity,demonstrating that telomerase activity is closely related to the cell vitality in plants.

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.

OBJECTIVEAntigen-presenting cells such as monocytes and dendritic cells (DCs) stimulate T-cell proliferation and activation during adaptive immunity. This cellular interaction plays a role in the growth of atherosclerotic plaques. Tanshinone II A (TSN) had been shown to decrease the growth of atherosclerotic lesions. We therefore investigated the ability of TSN to inhibit human monocyte-derived DCs and their T-cellstimulatory capacity.

METHODSDCs derived from human monocytes cultured with recombinant human interleukin (IL)-4 and recombinant human granulocyte-macrophage colony-stimulating factor were co-cultured with TSN and lipopolysaccharide for 48 h. Phosphate-buffered saline was used as a negative control. Activation markers and the capacity of DCs for endocytosis were measured by flow cytometry, and proinflammatory cytokines were measured by enzyme-linked immunosorbent assays. DCs were co-cultured with lymphocytes to measure T-cell proliferation and IL-2 secretion by mixed lymphocyte reactions.

RESULTSTSN dose-dependently attenuated DC expression of costimulatory molecules (CD86), and decreased expression of major histocompatibility complex class II (human loukocyte antigen-DR) and adhesion molecules (CD54). Moreover, TSN reduced secretion of the proinflammatory cytokines IL-12 and IL-1 by human DCs, and restored the capacity for endocytosis. Finally, TSN-preincubated DCs showed a reduced capacity to stimulate T-cell proliferation and cytokine secretion.

CONCLUSIONSTSN inhibits DC maturation and decreases the expression of proinflammatory cytokines, while impairing their capacity to stimulate T-cell proliferation and cytokine secretion. These effects may contribute to the influence of TSN on the progression of atherosclerotic lesions.

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.

Clinical reports on cardiac syndrome X (CSX) have been increasing in recent years. In general, CSX does not increase the cardiovascular mortality, but it can affect the patient's quality of life (QOL) and increase the incidence rates of cardiovascular and cerebrovascular events. Although a variety of drugs and therapies have been utilized in the clinical treatment, the management of CSX still represents a major challenge due to its unclear pathogenesis. It is necessary to explore more effective treatment programs. Many attempts have been made on trials of the Chinese medicine (CM) treatment for CSX and proved that CM has a certain advantage in efficacy to improve clinical symptoms and QOL. CM may provide a new approach for the effective treatment of CSX.
