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.

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.

Objective To study the effects of Baihu Rensen decoction combined with Fufang Xiebai capsules for treatment of patients with severe pneumonia accompanied by heat-phlegm and sthenic-fu syndrome.Methods A prospective study was conducted; 266 severe pneumonia cases with heat-phlegm and sthenic-fu syndrome admitted into the Department of Respiratory Diseases in Kunshan Hospital Affiliated to Jiangsu University from January 2012 to December 2013 were selected. The patients were randomly divided into a integrated traditional Chinese and western medicine group (136 cases) and a western medicine treatment group (130 cases). Both groups were given basic conventional western medicine according to the disease situation. The integrated traditional Chinese medicine (TCM) was additionally given Baihu Rensen decoction combined with 350 mg of Fufang Xiebai capsules, 3 times a day, 4 grain each time, 7 days constituting a course of treatment. The rate of body temperature descent, the degree of improvement in clinical TCM symptoms, peripheral white blood cell (WBC) count, neutrophil percentage and the situation of endogenous pyrogen production in the two groups were compared.Results After treatment, the body temperature, TCM symptom scores, WBC count and neutrophil percentage were lower than those before treatment, 3 days after treatment these data reached their valley values, and the decrease in level was more significant in the combination group [body temperature (℃): 36.5±0.0 vs. 37.0±0.0, TCM symptom scores: 1.7±0.2 vs. 6.1±0.7, WBC (×109/L): 7.1±0.3 vs. 8.3±0.5, neutrophil percentage: 0.64±0.02 vs. 0.76±0.23, allP < 0.05]. Interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), interferon (IFN-α, IFN-γ), and interleukin-6 (IL-6) level in western medicine (WM) group was respectively marked 1, the levels of IL-1β, TNF-α, IFN-α, IFN-γ, and IL-6 in combination group after treatment for 6 hours were significantly lower than those of WM group, and reached the valley at 12 hours (the relative expression value of each of the above indexes in combination group to each of those in WM group was 0.37, 0.16, 0.21, 0.27 and 0.15 respectively), and had a mild rebound at 24 hours.Conclusion By the addition of Baihu Rensen decoction combined with Fufang Xiebai capsules on conventional basic medicine for treatment of severe pneumonia patients with heat-phlegm and sthenic-fu syndrome, the therapeutic effect is much better.

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.

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.

Hyperhomocysteinemia is an independent risk factor for arterial and venous obstructive vascular di-seases. Raised plasma homocysteine concentrations are caused by genetic and non-genetic factors. The pathogenic mechanism is not clear. It may be associated with endothelium dysfunction, abnormal lipid metabolism, hypertrophy of intima media, increased platelet aggregation and several clotting factors interfered, etc. The metabolism and pathogenic mechanism of homocysteine are reviewed in this article, which provides theoretical foundation for the treatement of hyperhomocysteinemia.

BACKGROUND: Several studies have demonstrated that the range,thickness and morphology of oral prosthesis directly influence patient's phonetic function,and titanium base and polymethyl methacrylate(PMMA)resin base yield different influences on phonetic function due to different thicknesses of materials.OBJECTIVE: To analyze the phonetic parameters in one complete denture patient who wear titanium base and PMMA resin base simultaneously and investigate the influences of maxillary complete denture base on phonetic function.METHODS: Through the use of computer-based voice analysis software PRAAT4.4.34,frequency value of the first concentrated frequency area when speaking consonant sounds/x,sh,r,zh,ch,j,q/and voice onset time when speaking consonant sounds/g,k,zh,ch,j,q/were statistically analyzed in the same patient who separately wear titanium complete denture base and PPMA resin complete denture base,and spectrogram of velar stops between complete denture bases was compared.RESULTS AND CONCLUSION: MMPA resin complete denture base was to some extent poor in promoting the recovery of phonetic function owing to great base thickness.Titanium complete denture base with less thickness in the tongue or palate region would help recovery of phonetic function.Extraction and analysis of phonological parameters,such as frequency value of first concentrated frequency area and voice onset time,using CSL computer*based voice analysis system,would provide objective evidence for lamprophony analysis after wearing complete denture.Maxillary denture with thinner base in tongue and palate regions better promotes the recovery of patient's phonetic function.

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.

Objective:To analyze the curative effect of suppression expression of URG4 on cervical cancer mice and the possible mechanisms.Methods:The expression of URG4 were analyzed in cervical cancer tissues and para-carcinoma tissues.16 male BALB/c nude mice were divided into Group A ( inoculated with URG4-siRNA SiHa cells) and Group B ( inoculated with SiHa cells) . After 4 weeks,mice were executed and analyzed.Results:The expression of URG4 were higher in human cervical cancer tissues than that in para-carcinoma tissues ( P<0.05).After experiment,Group A had a lower tumor weight,but a higher body weight than these of Group B,the difference was statistically significant (P<0.05).Group A mice had a lower levels of URG4 in tumor than that of Group B mice (P<0.05).Group A mice had a lower levels of Ki67 in tumor than that of Group B mice,the difference was statistically significant (P<0.05).Group A mice had lower levels of CyclinD1,β-catenin and C-myc in tumor than these of Group B mice (P<0.05). Conclusion:The expression of URG4 in cervical cancer tissue is up-regulation.Suppression expression of URG4 can suppress tumor growth in vivo,which may though suppress the Wnt/β-catenin signaling pathway.
