The expression of WEE1 in gastric cancer and its influence on prognosis of patients / 实用肿瘤学杂志

Objective The aim of this study was to investigate the expression of WEE1 in gastric cancer and its influence on prognosis of patients. Methods Seventy-eight patients with gastric cancer were enrolled. According to the presence or absence of lymph node(LN)metastasis,the patients were divided into LN( -)group and LN( +)group. The expression of WEE1 in gastric canc-er tissues was detected by immunohistochemistry and RT-qRCR techniques. The influence of WEE1 expression on LN metastasis and prognosis of gastric cancer were analyzed statistically. Results (1)The positive rate of WEE1 in gastric cancer was 43. 6% ,of which 13 cases were a low expression and 21 cases with high expression. The positive rates of WEE1 in LN( +) group and LN( -) group were 53. 8% and 23. 1% ,respectively. (2)The results of RT-qPCR showed that the mRNA expression of WEE1 in LN( -)and LN ( +)groups was(1. 32 ± 0. 21) and(3. 64 ± 0. 41),respectively,and the difference was statistically significant(P<0. 01). (3) The results of ROC curve showed that the area under curve(AUC)of WEE1 mRNA expression level for LN metastasis of gastric cancer was 0. 806,the sensitivity was 84. 8% ,the specificity was 79. 6% ,and the diagnostic efficacy was good. T stage and LN metastasis were independent risk factors for the expression of WEE1(P<0. 05). (4)Among 78 patients,7 patients were lost to follow-up,the rate of loss of follow-up was 8. 9% ,and 41 patients died within 5 years. Among them,13,10 and 18 died in the WEE1( -)group,low-ex-pression of WEE1 group and high-expression of WEE1 group,respectively. The 5-year survival rates of the three groups were signif-icantly different(χ2 =25. 67,P<0. 001). The survival rate in the low expression of WEE1 group was not significantly different from the high expression of WEE1 group(P>0. 05),but both of them were significantly low the WEE1( -)group(P<0. 05). Conclusion WEE1 has a high positive rate in gastric cancer,and is closely related to patient stage and LN metastasis. The positive expression of WEE1 is a strong signal for poor prognosis.

Histological analysis of nano-hydroxyapatite for repairing defect in rabbit jaw / 中国组织工程研究

BACKGROUND: To repair bone defect, histocompatibility, growing characteristics, biodegradation and repairing mechanism of nanometer need to be further studied in clinic. OBJECTIVE: To observe the growing characteristics and histocompatibility of nano-hydroxyapatite (Nano-HA) for repairing jaw defect of rabbits.DESIGN: Randomized grouping animal study.SETTING: Beijing Jishuitan Hospital and Stomatology College of Jiamusi University.MATERIALS: A total of 24 New Zealand rabbits, either gender, weighing 2.5-3.5 kg, were provided by Animal Experimental Center of Jiamusi University. The animal experiment had got confirmed consent from local ethic committee. Nano-HA was provided by Material Engineering College of Jiamusi University and dealt with routine hyperthermia/hypertension sterilization. In addition, hydroxyapatite was provided by Wuhan Industry University, and the diameter was 1.0-2.0 μm.METHODS: The experiment was carried out in the Experimental Animal Center of Jiamusi University from November 2001 to May 2006. All rabbits were randomly divided into experimental group and control group with 12 in each group. Bone defect in the diameter of 1.0 cm was produced on body of mandible. Nano-HA was used to repair the bone defect of rabbits in the experimental group, while hydroxyapatite was used to repair the bone defect of rabbits in the control group. At 1, 4, 8 and 12 weeks after operation, all rabbits were sacrificed. In addition, medical imaging analysis system was used to analyze generative quantity of tissue in the two groups; meanwhile, histological quality and quantity were also analyzed so as to observe histocompatibility and newborn osteogenesis. MAIN OUTCOME MEASURES: Histocompatibility and newborn osteogenesis.RESULTS: With the time passing by, the amount of repairing materials was decreased because of the combination with newborn tissue into bone in bone defect-repaired region in the experimental group. When it was closed to normal bone, the amount was stable. However, bony callus was not able to grow in materials in the control group. Results of correlation analysis demonstrated that materials were negatively straight-line correlation with newborn bone (r = -0.912 0, P < 0.01). During the repairing procedure of bone defect, newborn bone was closely correlative with Nano-HA; while, with the increase of newborn bone, the amount of repairing materials was decreased because of the combination with newborn tissue into bone.CONCLUSION: Nano-HA can combine with newborn bone tissue so as to rapidly generate bone, while it has an excellent biocompatibility.
