Objective:This study has two objectives. One is to detect the methylation status of reversion-inducing cysteine-rich protein with Kazal motifs (RECK, a new tumor suppressor gene) gene promoter in primary laryngeal squamous cell carcinoma and nor-mal laryngeal mucosa. The other is to analyze the correlation between RECK gene methylation status and radiosensitivity in laryngeal squamous cell carcinoma. Methods:Methylation-specific polymerase chain reaction was used to detect the RECK gene methylation of 70 specimens of laryngeal squamous cell carcinoma and 15 normal tissues of laryngeal mucosa. The patients underwent six cycles of ra-diotherapy and were followed-up for 5 years. The correlation between RECK gene methylation status and radiosensitivity in laryngeal squamous cell carcinoma was analyzed. Results: After six cycles of radiotherapy, 47 patients (67.14%) showed sensitivity and 23 (32.86%) showed tolerance to radiotherapy. The methylation level of the RECK gene was lower in the radiation-sensitive group than in the nonradiation-sensitive group (P<0.05). The methylation level of the RECK gene was lower in the remission group than in the non-remission group. RECK gene methylation could increase the risk of cancer by approximately 5.010 times (OR=5.010, 95%CI:1.616-15.533). Conclusion:RECK gene promoter methylation in human laryngeal squamous cell carcinoma is an early event that is correlated with the patient's sensitivity to radiotherapy. Thus, the patient's sensitivity to radiation can be predicted by detecting the meth-ylation status of the RECK gene promoter.

Objective To study whether p38 mitogen-activated protein kinases (p38MAPK) signal pathway were activated in the process of tumor necrosis factor-like weak inducer of apoptosis (TWEAK) which then induces rheumatoid arthritis (RA) fibroblast-like synoviocyte (FLS) to synthesize matrix metalloproteinase-1 (MMP-1) and look for the relative mechanisms of how TWEAK was involved in the destruction of articular bones and cartilage. Methods RA FLS were primarily cultured and stimulated with TWEAK. FLS were pretreated with SB203580 or not. ELISA was used to detect the concentration of MMP-1 in cell-cultured supernatant. Western blotting was used to detect the expression of p-p38MAPK and P65 in RA FLS. Results TWEAK (100 ng/ml) could induce RA FIS to synthesize MMP-1. SB203580 could partially inhibite the expression of MMP-1 producted by RA FLS which was induced by TWEAK. TWEAK could make p38MAPK phosphorylated and increase the expression of P65 protein in the cell nucleus. Conclusion TWEAK induces RA FLS to synthesize MMP-1. In this process, p38MAPK signal transduction pathway is activated and then induce the expression of NF-κB.

Objective To compare the results of the three grades pictures affiliated With the Synotophore and to choose the opti- mal pictures for the clinician.Design Retrospective case series.Participants 41 normal persons and 44 cases of intermittent exotropia. Methods All participants were separately examined the three grades function with different kinds and degrees pictures affiliated with the Synotophore.The average radian measured with four sorts of pictures of the first grade function and the average measured with the three sorts of pictures of the second grade function were analysed,the stereoacuity of third grade function was measured with qualitative picture and random dot quantitative picture.Comparison was made between two groups of the people who possessed with stereoacuity. Main Outcome Measures Radians and seconds gained from the pictures affiliated with the Synotophone,Results Synotophore of the superposition of the first grade function:the outcome of using four sorts of pictures to examine the normal persons were 1.47+1.68, 1.21?1.21,1.68?1.60,1.32?1.27,F=0.595,P=0.619;the intermittent exotropias were 8.41?4.30,8.73?4.26,8.45?3.86,8.73?4.28,F= 0.070,P=0.987;the difference was not prominent.The fusion range of the second grade of Synotophore,using three different pictures to examine the normal persons were 26.03?6.17,21.11?6.87,17.21?5.40,F=17.260,P=0.000,the result of the fusion range has direct proportion with the degrees of the pictures,the bigger the picture was,the larger the fusion range,the difference was statistically signif- icant.And there was no significant differences for the intermittent exotropias when examined with the same pictures(21.74?7.43,21.31?7.82,20.32?7.53),F=0.590,P=0.556.The stereoaeuity of the third grade of Synotophore,in the normal person group 85.4% and 100%, X~2=4.877,P=0.027,the results were statistically significant between the qualitative picture and the random dot quantitative picture. About the intermittent exotropia group,no statistically significant differences were detected(72.73% and 59.10%),X~2=1.821,P=0.177. Condusion Choose pictures randomly when examine the first grade function of Synotophore;for the second grade function of Syno- tophore in both groups may choose intergraded degree pictures;the stereoacuity of the third grade of Synotophore,normal group should choose quantitative pictures,while strabismic patients may choose both of them.(Ophthalmol CHN,2008,17:120-122)

Objective To investigate the characteristics and distribution of class teaching skill points in state high quality course pathology using Flanders interaction analysis system to analyze the teaching video of pathology course.Methods Teaching videos of state high quality course (pathology course) between 2006 and 2012 were analyzed by Flanders interaction analysis system.Frequencies of using teaching skill,presentation skill and interaction skill were statistically analyzed.Results The study found that frequencies of using teaching skill points in pathology course were decreased in the following order:presentation skill (53.94％),interaction skill (26.64％) and teaching skill (19.42％).Sensory focusing was most commonly used in presentation skill.Monitoring and expressing concern were most commonly used in interaction skill.Gestures and cases were most commonly used in teaching skill.Conclusions Teachers in pathology teaching should correctly handle the relationship among the presentation,interaction and teaching skills according to the teaching objectives and teaching content.

Objective To describe the CT features of giant lymph node hyperplasia in abdomen.Methods A retrospective study of CT features of giant lymph node hyperplasia in abdomen confirmed by surgery or biopsy pathology was performed.CT findings of all lesions were assessed by two radiologists including size,location,pattern of enhancement and density characteristics.Results 1 2 patients with giant lymph node hyperplasia in abdomen were confirmed including 7 women and 5 men with age range from 11 to 75 years (median age 3 9 years).All patients underwent pre-and post-contrast enhanced CT.CT showed a single mass in 9 patients lo-cated at retroperitoneum in 5,porta hepatic in 2,and mesentery in 2.Multiple masses were located at chest,abdomen and neck in 3.The lesions ranged in size from 1.2 to 11.9 cm in maximum diameter with an average size of 3.7cm.CT showed all lesions with well-defined margin and regular shape.The lesions less than 5 cm in diameter usually showed homogeneous enhancement,and how-ever those more than 5 cm showed heterogeneous enhancement.The calcification was seen in two patients.Conclusion CT features of giant lymph node hyperplasia in abdomen are characteristic.

Objective To investigate the expression of human epididymal protein 4 (HE4) in chronic kidney disease (CKD) and its clinical value.Methods From April 2014 to December 2015,Serum samples of 92 non-cancer patients diagnosed as CKD and 84 healthy controls were collected in Nantong University Hospital.HE4,BUN,Scr,Cys C and β2MG were detected.The difference of HE4 expression in different stages of CKD and the correlation of HE4 with Urea,Scr,Cys C and β2MG were analysized,respectively.ROC curve was used to evaluate the auxiliary diagnostic value of HE4,BUN,Scr,Cys C and β2MG.Results The serum HE4 expression in patients with impaired renal function was 388.2 (130.1～1 659.5)mIu/ L,(F=16.237,P=0.001).Which was significantly higher than that in the control group [38.1 (32.77 ～ 48.17)mIu/L].The serum HE4 expression was increased by the stage of renal damage and the difference was existed among different groups (P＜0.05).HE4 expression was positive related with Cys C and β2MG.The AUC of HE4,BUN,Scr,Cys C and β2MG were 0.878,0.785,0.816,0.874 and 0.819,respectively.Conlusion It needs to consider the exsits of impaired renal function when the HE4 was detected.The HE4 might be a novel early diagnostic indication for CKD.
