Zinc-fingers and homeoboxes 2 (ZHX2) is a novel transcriptional repression factor participating in regulating the expression of alpha fetal protein (AFP). ZHX2 has been confirmed to be largely correlated with development and metastasis of hepatocellular carcinoma (HCC) and invasion of multiple myeloma.

0.05). The 5-year survival rates were 77.4% in LS group and 75.7% in OS group for stage Ⅰ/Ⅱ (P=0.626), and 71.8% in LS group and 65.6% in OS group for stage Ⅲ(P=0.517), respectively. Conclusion: Long-term effect of laparoscopic resection is similar to that of open resection for colon cancer, but laparoscopic surgery has less long-term complications.

Objective To explore and evaluate the clinical value of MRI for status of axillary lymph node after neoadju-vant chemotherapy (NAC) in patients with breast cancer. Methods Forty-four patients with 1ocally advanced breast cancer (LABC) were underwent NAC for four cycles. The longest diameter of axillary lymph node (ALN) measured by MRI scan. Val-ue of apparent diffusion coefficient (ADC) and their correlation were compared before NAC and four cycles after NAC. Re-sults of MRI and pathological data for ALN were compared between two groups of patients. Results All patients finished four cycles of NAC. The total response rate (CR+PR) was 72.7% (32/44), and the total non-response rate (SD+PD) was 27.3%(12/44). The longest diameter of ALN was significantly shortened in response group. The longest diameter was (1.37± 1.06) cm before NAC and (0.90±0.76) cm after NAC (P<0.01). The ADC value of the tumor was significantly increased in re-sponse group [(0.91±0.28) ×10-3 mm2/s before NAC and (1.01±0.32)×10-3 mm2/s after NAC, P<0.01)]. There was no signifi-cant correlation between ADC value change (△ADC) and the longest diameter change of ALN (△L, r=0.131, P=0.413). The sensitivity, specificity and Kappa value of ALN evaluation after NAC were 100%, 62.5%and 0.68 measured by MRI. Con-clusion The change of tumor longest diameter reflects the effect of chemotherapy directly. The tumor ADC value of MRI can not be used as an independent indicator of chemotherapy effect of ALN, eventhouth MRI was the sensitive index for eval-uating the status of axillary lymph node after neoadjuvant chemotherapy for breast cancer.

Objective To explore the migration of transplanted neural stem cells labeled with SPIO with 4.7T MR system and study cell differentiation by immunohistochemistry in ischemic rats. Methods Rat neural stem cells(NSCs)co-labeled with SPIO mediated by poly-L-lysine and bromode- oxyuridine(BrdU)were transplanted into the middle cerebral artery occlusion(MCAO)rats after 14 days when MCAO model was made successfully.4.7T MR scanner was used to monitor the migration of transplanted cells after 1.2,3,4,5 and 6 weeks post-transplantation.After MRI examination at 6th week,the rats were killed and Prussian blue staining and immunohistochemistric staining were per- formed to study migration and functional differentiation of NSCs.Results Three weeks after trans- plantation,linear hypointensity area derived from migration of labeled NSCs was observed in the corpus callosum adjacent to the injection site.Six weeks after transplantation,linear hypointensity area was moved toward the midline along the corpus callosurn.MRI findings were confirmed by Prussian blue staining and immunohistochemical straining.Co-labeled immunohistochemical methods demonstrated transplanted NSCs could differentiated into astrocytes and neurons.Conclusion MRI is very useful in demonstrating the migration path of labeled NSCs.Transplanted NSCs into ischemic rats can differen- tiated into astrocytes and neurons during the process of migration.

Aim To evaluate the antianginal efficacy of trimetazidine in combination with other regular anti-ischemic drugs in the treatment of stable angina. Methods Twenty-two male cases with stable,effort-induced angina and positive exercise ECG test were treated with trimetazidine for 12 weeks.Exercise ECG test was examined again in the end of the study. Results There were obviously increased in exercise tolerance,total exercise workload after treatment(P

Oxaliplatin, the third generation of the platinum based chemotherapy agent, is effective in the treatment of multiple solid tumors and is also quite safe. However, there is a high incidence of peripheral neurotoxiciy, which is dose-limiting. Oxaliplatin induces two distinct forms of neurotoxicity: an acute syndrome that is triggered or aggravated by exposure to cold, and chronic cumulative sensory neurotoxicity which in nature resembles characteristics of cisplatin associated neurotoxicity. In this article, the clinical manifestations, electrophysiologic abnormalities, mechanism of neurotoxicity and therapy are reviewed.

This study investigated the effect of etoposide, an anticancer chemotherapy drug, on B7-H1 expression in retinoblastoma (Rb) cells and the role of miR-513a-5p in the process. Rb cells were divided into control and etoposide groups. In the etoposide group, cells were treated with etoposide at different concentrations (2.5, 5, 10, 20 and 40 μg/mL) for 24 h. Those given no treatment of etopside served as controls. Reverse transcription polymerase chain reaction (RT-PCR), fluorescence quantitative PCR and flow cytometry were performed to measure the mRNA and protein expression of B7-H1 in Rb cells. The mRNA expression of miR-513a-5p in Rb cells before and after etoposide treatment was also detected by fluorescence quantitative PCR. The miR-513a-5p mimics and the miR-513a-5p inhibitor were transfected into Rb cells separately, and fluorescence quantitative PCR and flow cytometry were used to detect the effect of the miR-513a-5p mimics or inhibitor on B7-H1 expression. TargetScan5.2 was employed to predict the miR-513a-5p binding sites in the 3'-untranslated region of B7-H1 mRNA. Luciferase reporter plasmids carrying this site were prepared and transfected into Rb cells and luciferase activity analyzed. The results showed that etoposide stimulated the mRNA and protein expression of B7-H1 in Rb cells, which reached a maximal level after treatment with 5 μg/mL etoposide (P<0.05). However, miR-513a-5p expression was decreased in Rb cells after etoposide treatment. When the miR-513a-5p inhibitor was added, B7-H1 expression was increased with the concentration of the miR-513a-5p inhibitor (P<0.05). Moreover, B7-H1 expression was decreased gradually with the concentration of the miR-513a-5p mimics increased (P<0.01). Additionally, the miR-513a-5p mimics were found to inhibit the luciferase activity. It was concluded that etoposide can promote B7-H1 expression in Rb cells, which may be associated with chemoresistance. The promoting effect of etoposide on B7-H1 expression can be reversed by miR-513a-5p mimics. MiR-513a-5p inhibits the mRNA and protein expression of B7-H1 via binding to the 3'-UTR of B7-H1 mRNA.

After several thousand years of development,TCM has formed its own sets of research methods.such as observation,comparison,classification,trial and error,and deduction,etc.Based on the unique TCM theory,experiences of clinical diagnosis and treatment of TCM,the author put forward that the research of TCM should combine macrophenomenon and microphenomenon,quality and quantity,and"Zheng"and"Xie",emphasize locality feature for the purpose of promoting the science research level.
