ABSTRACT

Objective@#To discuss the surgical method and clinical effect of applying the facial artery perforator-based nasolabial para-nasal advanced flap to repair the medial canthus and inner lower eyelid skin defects.@*Methods@#The advance nasolabial para-nasal perforator flap supplied by facial artery, was used to repair the medial canthus and inner lower eyelid skin defects, caused by dermatoma excision.@*Results@#All 18 flaps completely survived. The detects in the medial canthus andinner lower eyelid, and the donor sites in the nasolabial fold were primary healed.The medial canthus and inner lower eyelid were recovery satisfactorily.The flaps were not bloated, and the contour and texture of flaps were similar to adjacent tissue, with no need of secondary repair.The donor site was successfully hidden in the nasolabial dermatoglyph.@*Conclusions@#Nasolabial para-nasal perforator flap is easily obtained, reliable in blood supply, and flexible in transfer. It has a wide range of movement and is easy to advance, so as to repair medial canthus andinner lower eyelid defect. With above advantages, this flap is worthy towidely popularize.

ABSTRACT

Objective:To investigate the correlation between the expression of Golgi phosphoprotein 3 (GOLPH3) and the occurrence of apoptosis in colorectal cancer cells (CRC). Methods:Immunohistochemical assays of GOLPH3 and caspase-3 were performed on the paraffin-embedded sections of 62 CRC samples using the standard streptavidin-peroxidase technique. The apoptotic index of the CRCs was examined using the in situ terminal deoxynucleotidyl transferase nick-end labeling technique. The relationship of the GOLPH3 expression, the cell apoptosis, and the clinicopathologic parameters was analyzed. Results:The positive rates of GOLPH3 expression were significantly higher in the CRC tissues (53.2%) than in the normal colorectal mucosa (37.2%;P0.05). The caspase-3 expression and apoptotic index were significantly lower in the GOLPH3-positive CRC tissue than in the GOLPH3-negative tissue (P<0.05). GOLPH3 expression was negatively correlated with the apoptotic index of CRCs based on the Spearman correlation (r=-0.320, P<0.05). Conclusion:GOLPH3 overexpression in CRC tissue is negatively correlated with apoptotic index.

ABSTRACT

Objective To study the relationship between the number of examined lymph nodes and the prognosis of colorectal cancer by TNM stage. Methods According to the number of examined lymph nodes, 567 patients of colorectal carcinoma who underwent resection were divided into three groups: ≤ 6,7-11 and ≥ 12, the 5-year overall survival rates of three groups were compared. For each TNM stage ( stage Ⅰ -Ⅳ ) , patients were substratified into two groups basing on the number of examined lymph nodes:0. 05 ) , however, the 5-year survival rates of stage Ⅱ and Ⅲ colorectal cancer in ≥12 group were significantly higher than<12 group(71. 1% vs. 32. 6% ,48. 8% vs. 30. 0% ,P<0. 05) , multivariable analysis revealed that the number of lymph nodes examined was an independent factor of prognosis of stage Ⅱ and Ⅲ colorectal cancer. Conclusions The number of examined lymph nodes significantly influenced the 5-year overall survival rate of TNM stage Ⅱ and Ⅲ colorectal cancer.

ABSTRACT

We have made a cheap microsystem of capillary electrophoresis with a new method, integrating the electrodes, injection channel, separation channel, buffer reservoirs and detection cell on a polymethylmethacrylate (PMMA) chip. Using an integrated micro carbon fiber disk electrode as the working electrode in three electrodes system, 1 × 10-4 mol/L dopamine (DA) could be detected with end-column amperometric detection. The reproducibility was good. Peak current was 6.73 nA、theoretical plate numher was 71300/m and height equivalent of one theoretical plate height was 14.0 μm for 1 × 10-4 mol/L DA. The limit of detection was 3.6× 10-8mol/L and the linear range was extended from 5 × 10-7 mol/L to 1 × 10-4 mol/L for DA. 1 × 10-4 mol/L catechol (CA) and 5× 10- 5 mol/L DA were also separated completely with R. = 10.1.
