Serious troubles were caused by the highly heterogeneous cancer cells in clinical cancer treatment.In recent years,molecular characterization of tumors and corresponding individualized cancer management has become hotspots for cancer research.Circulating tumor cells (CTCs) are shed from primary solid tumors or metastases into the peripheral blood.CTCs could serve as liquid biopsy for patients with cancer,with non-invasive,real-time and repeatable access.Serial monitoring of the amount and molecular characteristics of CTCs in the blood samples has significant clinical value for prognostic prediction,targeted drugs choice and real-time evaluation of clinical effectiveness in individualized cancer treatment.This review summarizes current methods for the CTC isolation and detection,and discusses the perspectives of CTC analyses in real-time personalized cancer therapy.Some future research directions in this field are proposed.

Objective To study the mechanism of arsenic on human lung adenocarcinoma cells.Methods MTT,FCM and RT-PCR tests were used to investigate apoptosis levels induced by arsenic trioxide and the effect on LRP mRNA expression.Results 1.0μmol/L and 3.0μmol/L arsenic trioxide can decrease LRP mRNA expression.Conclusion Low concentration As_2O_3 may improve apoptosis of lung caner by decreasing LRP mRNA expression.As_2O_3 may be used to treat lung cancer but the results are not better than cisplatin.

Cis-3, 4-dichloro -a-chloro-cinnamoyl-sec.-butylamine (8601), a new compound of cinnamamides, has potent antagonistic effect on experimental epilepsy. 8601 is significantly more effective against MES in mice than Antiepilepsirine. It has also been found effective against convulsion induced by icv. injection of sodium glu-tamate and zinc sulfate.The mechanisms of anti-MES of 8601 is related to content of 5 HT in the whole brain of mice. Increased cerebral 5 HT with L-tyrosine potentiated the effect of anti-MES of 8601,while the opposite was obtained using reserpine or pCPA which decreased the concentration of cerebral 5 HT. The increase of cerebral 5 HT is correlated with the effect of anti-MES of 8601 with a correlation coefficient of 0.926 ( P

Objective To determine the relationship of the expression of aquaporin 5 (AQP5)with clinicopathology and prognosis of colorectal cancer.Methods We collected data from 45 patients with primary colorectal cancer without any adjuvant therapy before operation.The expression of AQP5 was measured by immunohistochemistry (IHC).Then we analyzed the correlation between AQP5 expression and clinicopathological parameters (including age,tumor size,clinical staging,tumor location,lymph node and pathological type)and the connection between AQP5 expression and prognosis based on follow-up data.Results Of the 45 tumor specimens,14 (31.1%)had a high level of AQP5 expression,29 (64.4%)exhibited a moderate level of staining,and 2 (4.4%)had an absence of AQP5 staining.AQP5 was only occasionally detected in para-neoplastic [3/45 (6.67%)]and normal tissues [3/45 (6.67%)].The overexpression of AQP5 was also positively associated with TNM stage (P =0.002),lymph node metastasis (P =0.01 6),and distant metastasis (P =0.000).However,it had no significant association with age, gender,histologic grade or tumor size (P > 0.05 ).Conclusion AQP5 may be used as a novel biomarker for predicting the prognosis of colorectal cancer.

To study the protective effect of Danqi Piantan capsule ( DPC) and its antelope horn substitution (DPCAS) on the cerebral ischemia, in order to preliminary study the possibility of replacing antelope horn with artificial bezoar. In this study, the left middle cerebral artery occlusion (MCAO) was adopted. Totally 150 SD rats were randomly divided into 5 groups: the sham operation group, the model group, the Danqi Piantan capsule (DPC) group (0.246 g x kg(-1) x d(-1)), the Danqi Piantan capsule without antelope horn (DPCRA) group (0.246 g x kg(-1) x d(-1)), the Danqi Piantan capsule without antelope horn and with double artificial bezoar (DPCDB) group (0.246 g x kg(-1) x d(-1)). The MCAO model was prepared 1 h later after the administration on the 5th day. At 24 h after the operation, the inner canthus blood was collected to determine the serum superoxide dismutase (SOD) activity and the endothelin (ET) content. At 72 h after the operation, the cerebral infarct size and the cerebral index were determined by TTC-staining. The fluorescent quantitative PCR method was used to detect brain Bcl-2, Caspase-3, IL-1β, P-selectin, E-selectin, ICAM-1 mRNA expressions. The mmunohistochemical method was used to detect ICAM-1, IL-1β, TNF-α, IL-6 expressions in ischemic penumbra. According to the results, compared with the model group, DPCDB and DPC groups showed almost consistent results, indicating both of the two group can significantly improved cerebral infarction index and cerebral index (P < 0.05), increase the serum SOD activity (P < 0.05), decrease the serum ET level and Caspase-3 expression, IL-1β, P-selectin, E-selectin, ICAM-1 mRNA expressions in brain tissues (P < 0.05) and expressions of ICAM-1, IL-1,6, TNF-α, IL-6 positive cells in ischemic penumbra (P < 0.05) and increase the Bcl-2 expression (P < 0.05). The DPCRA group showed much lower impacts on indexes than DPCDB and DPC groups. This suggests that DPCDB and DPC reveal similar efficacies and antelope horn in Danqi Piantan capsule can be substitutes by artificial bezoar.

The in vitro cell culture experiment was conducted to study the effect of Danqi Piantan capsule (DPC) and DPC dislodge the antelope horn with artificial bezoar double (DPCBD) on nerve regeneration and blood vessel regeneration and preliminarily investigate the possibility of substituting antelope horn in DPC with artificial bezoar. In this experiment, rats were randomly divided into 5 groups: the blank serum control group, the model group, DPC groups (0.306 g x kg(-1) x d(-1), the same below), DPC remove of antelope horn (DPCRA) groups and DPCBD groups. Brain microvascular endothelial cells cultured in vitro (BMEC), astrocytes and neural stem cells (NSC) were co-cultured to simulate neurovascular unit, label neurons with microtubule associated protein III (β-tubulin III) antibody and lable astrocytes with glial fibrillary acidicprotein (GFAP). ELISA was used for the detection of the content of BMEC lactate dehydrogenase instrument method (LDH), the inverted phase contrastmicroscope was adopted to observe the formation of BMEC tube like structure, the number of leukocytes and leukocytes adherent to BMEC were counted under the microscope, the expression levels of β-tubulin III and the ratio of GFAP positive cells was detected with inimmunofluorescence, and RT-PCR method was used to detect NGF, BDNF, VEGF and VEGFr-2 mRNA. According to the result, compared with the model group, both DPC and DPCBD can reduce LDH leakage, promote the formation of BMEC tube like structure, inhibit leukocytes and their adhesion to BMEC, increase the β-tubulin III positive cell differentiation proportion (P < 0. 01), reduce the proportion of GFAP positive cells (P < 0.01), increase the expressions of co-cultured NGF, VEGF, BDNF and VEGFr-2 mRNA to a certain extent, with the most significant difference on NGF and VEGF mRNA expressions (P < 0.05) and the same efficacy in both groups. DPCRA groups showed less impact on all indexes than that of DPCBD and DPC groups. The same efficacy of DPCBD and DPC on nerve regeneration and angiogenesis suggested that antelope horn in DPC can be substituted by artificial bezoar.
