Journal of International Oncology 2012;(11):815-817
Ezrin protein plays an important role in morphogenesis,motility,adhesion.Moreover,Ezrin protein participates in multiple steps of the process of tumor invasion and metastasis.In the progress of tumor metastasis,Ezrin protein is related to several signaling pathways such as Rho mediated signaling pathways,hepatocyte growth factor (HGF) pathways,Fas mediated cell apoptosis signaling pathways,phosphatidyl inositol 3-kinase (PI3K)-Akt pathways,and in which it plays different regulatory role.
2.Orthopantomography and cone-beam CT for bone height measurement and simulation in posterior implant region
Chinese Journal of Tissue Engineering Research 2017;21(20):3152-3157
BACKGROUND: Cone-beam CT (CBCT) and orthopantography are two imaging methods mostly used in the preoperative evaluation of dental implantation. CBCT has high cost and low penetration rate, but orthopantography can result in a larger error in the measurement of bone quantity.OBJECTIVE: To compare the accuracy of bone quantity measurement using CBCT and orthopantography, and to evaluate the clinical effect of simulation in posterior implant region. METHODS: 115 implants from 72 patients undergoing implantation of posterior teeth in the Eye & ENT Hospital of Fudan University were selected. The horizontal heights from the top of the alveolar bone to the important anatomic structures (mandibular nerve or maxillary sinus floor) were measured using CBCT and orthopantography and then analyzed statistically. The implantation simulations were performed using Planmeca Romexis3.8 (for CBCT) and Cliniview9.3 (for orthopantography) to compare the differences in stimulated and postoperative horizontal heights.RESULTS AND CONCLUSION: There were significant differences in the measured data between CBCT and orthopantography (P < 0.05), especially in the maxilla (P < 0.01). There were significant differences between the simulated and postoperative results of the two methods (P < 0.05). The average error and standard deviation in orthopantography were larger than those in CBCT. The average error of implantation simulation using CBCT in the maxilla was smaller than that using orthopantography, whereas the error was similar in mandibular simulations. To conclude, CBCT is more accurate for assessing the quantity of bone in posterior implant region, especially in the maxilla. The accuracy of CBCT and orthopantography in implantation simulation needs to be improved.

4.Changes in retinal structure and function of Alzheimer's patients
International Eye Science 2017;17(10):1867-1870
Alzheimer's disease( AD) , a neurodegenerative disease, can result in memory loss, cognitive and behavioral deficits. The pathological hallmarkes are β amyloid plaques and neurofibrillary tangles which lead loss of neurons in brain. As the extension of the central nervous system, retina has a similar tissue anatomy with central nervous system. The β amyloid plaques have also been detected in retina of AD. Furthermore, according to eye examinations of AD patients, we have found the loss of retinal ganglion cells, the attenuation of retinal nerve fiber layer thickness, the smaller changes of macula lutea, the decline of vascular density and so on. And then, there occurs the visual field loss and the decline of contrast sensitivity and so on in AD patients. Thus, the retina has occurred nerve degenerative changes in AD. Meanwhile, there has been proved that the retina nerve degeneration is even earlier than senile plaques formation in brain. In addition, curcumin, a natural and safe fluorescent dye, can be used to label β amyloid plaques in retina. The above suggests that retina can be a window for the early diagnosis of AD.

7.Differential expression of Ezrin in cervical cancer tissues and the relationship between Ezrin and PCNA, MMP-2, MMP-9, HPV
China Oncology 2013;(11):904-909
Background and purpose:Previous studies have revealed potential roles for Ezrin in a variety of cancers. Ezrin participates in several functions including cell adhesion, motility and cell survival, and there is increasing evidence that it regulates tumour progression. This study aimed to determine the differential expression of Ezrin between cervical cancer tissues and normal controls and to explore the association of Ezrin expression with clinical pathological characteristics and with the expression of PCNA, MMP-2, MMP-9 and HPV E6 protein. Methods:Retrospective study was performed among 30 cervical cancer tissue samples which were diagnosed in our hospital from Jan. 2002 to Dec. 2006. Ten normal cervixes from uterine myomas were employed as normal controls. Semi-quantitative immunohistochemisty analysis was performed to detect the association of Ezrin expression with clinical pathological characteristics, and with expression of PCNA, MMP-2 and MMP-9, HPV E6 protein in cervical cancer tissue and normal controls. Analyze the association of Ezrin expression with the clinical characteristics. Results:The expression of Ezrin was strong and the distribution was diffuse mainly in the cytoplasm and membrane in cervical cancer tissues, while the normal cervical tissues was weak and mainly in the membrane. However, there was no signiifcant association between the expression of Ezrin and the clinical characteristics including tumor stage, histology and grade. Ezrin expression was positively correlated with the expression of MMP-2, MMP-9 and HPV E6 protein in cervical cancer tissues, except PCNA. Conclusion:Ezrin was over-expressed in cervical cancer tissues and may be involved in the progress of invasion and metastasis in cervical cancer.

HMG-CoA reductase inhibitor, routinely utilized in the treatment of hypertriglyceridemia, does not decrease serum levels of triglyceride (TG) as much as it decreases levels of cholesterol. Clofibrates, on the other hand, quite effectively decrease triglyceride levels but severe adverse effects have been reported. Dandao-paishi-tang, a Chinese herb combination, generally used to promote the passage of gallstones, was modified and used to treat three patients with hypertriglyceridemia. A male with hypertriglyceridemia, mild hypertension, and cholelithiasis began to take modified Dandao-paishi-tang when 55 years old. Serum TG level decreased from 634mg/dl to 273mg/dl over four years of treatment. A 66-year-old female patient with hypertriglyceridemia and diabetes took the prescription for four months and TG decreased from 815mg/dl to 442mg/dl. A 76-year-old female with mild hypertriglyceridemia showed a decrease in TG from 154mg/dl to 132mg/dl in four months.
