Objective To explore the role of claudin-3, claudin-4 in carcinogenesis and progression of ovarian mucous cystoadenocarcinoma. Methods Immunohistochemical and in situ hybridization method were employed to detect the expression of claudin-3, -4, claudin-4 mRNA in ovary epithelium, mucinous cystadeno-nut, mucinous cystadenoma of borderline, mucous cystadenocarcinoma. Results claudin-3, -4 expression was lowest in ovarian epithelium and mucinous cystadenoma, higher in borderline mucinous cystadenoma, and high-est in ovarian cystadenocarcinoma(P<0.05 ). The expression of claudin-3, -4 in poor differentiated ovarian carcinoma was stronger than that in well- differentiated and moderately differentiated carcinoma (P< 0.05 ),but there was no significant difference between well-differentiated and moderately differentiated carcinoma(P>0.05). Conclusion The overexpvession of claudin-3, -4 is correlated closely with the carcinogenesis and advancement of ovarian mucinous carcinoma, and may have correlation with the differentiated degree of o-varian carcinoma, claudin-3, -4 may become the specific markers of ovarian mucous cystadenocarcinoma.

Medical examination is an important measurement of evaluating the teaching effect and studying results,and also is the main method and content of teaching quality evaluation in universities and colleges.During the teaching evaluation we found that many problems of medical examination need to be solved and improved.This paper deals with three major aspects closely related to teachers including the standardization of programming test paper,rating the test scores,and statistical analysis of the examination papers.

Objective:In 2003,a survey of the manpower of pediatric dentists was made in China in order to provide basis for database. Methods:Questionnaires were distributed to dentists presenced the 5th conference of pediatric dentistry in China,and 139 available answers were analysis. Results:In those 139 pediatric dentists, with a mean age of 38.2?8.7,females were significantly more than males, and 89.9% dentists had bachelor, master or doctor degree. Significant relations were found between self-estimate ability of dentists and their length of work, degree, character of clinic.Conclusion:To date, the team of pediatric dentists begins to take shape, the structure of age and education are rational, but the number of them is insufficient and it is necessary to improve the basic and continuing education.

Objective To investigate the clinicopathologic features and the expression of p53,PCNA and Bcl-2in tricholemmal carcinoma.Methods Skin lesions were studied with HE staining and immunohis-tochemical markers for p53,PCNA and Bcl-2(S-P method)in22cases of skin tricholemmal carcinoma.Both morphological manifestations and immunohistochemical expression were observed.Results There were15fe-male and7male cases of tricholemmal carcinoma with the ages of40-79y,including16cases whose scalp were involved.Positive staining of p53,PCNA and Bcl-2was found in72%,100%and63%of patients,re-spectively.The positive cells of p53were diffusely distributed.PCNA-positive cells were increased along with the degree of differentiation.Significant differences of Bcl-2expression were found among the various degrees of differentiation(P

Objective To explore the alterations, relationship and clinical significance of CD4 +CD25 +CD127 low/ -
regulatory T cells ( Treg ) and lymphocyte subsets in peripheral blood of patients with acute myelocytic leukemia ( AML) . Methods The level of peripheral blood lymphocyte subsets and Treg of untreated AML patients and com-plete remission( CR) patients were tested by flow cytometry,and were compared with that of 30 normal controls. Re-sults The proportions of Treg were much higher in untreated AML patients and CR patients than in normal con-trols, while the mean proportion of Treg in untreated AML patients was higher than that in CR patients(P<0. 05). The proportions of NK( CD3 -CD16 +CD56 +) cells in untreated AML patients and CR patients were both decreased compared with normal controls,and the mean proportion of NK cells in untreated AML patients was lower than that in CR patients(P<0. 05). Compared with the normal controls,the proportions of CD3 +T cell, CD4 +T cell,and the ratio of CD4 +/CD8 + decreased in untreated AML patients ( P <0. 05 ) , but the proportions of CD8 +T cell was higher than in normal controls;the proportions of CD3 +T cell, CD4 + T cell, CD8 +T cell and the ratio of CD4 +/CD8 + in CR patients were close to the proportions in normal controls, but there was significant difference between CR patients and untreated AML patients(P<0. 05). Conclusion The increase of Treg, CD8 +T cell and decrease of NK cells, CD3 +T cell, CD4 +T cell, and the ratio of CD4 +/CD8 + in peripheral blood of patients with AML in-dicate that the immune function of patients with AML is depressed. Treg control the immune response of CD8 +T cells,at the same time inhibit the natural immune response of NK cells, playing a major role in the disorders of CD4 +T cells and CD8 +T cell balance,and closely relate with the development of AML. The immune treatment of patients with AML will be optimised by reducing the amount of Treg or removing the suppression function.

Objective To explore changes of procedural memory in patients with primary insomnia(PI) and its characteristics.Methods Thirty-six PI patients and 36 controls were enrolled.The procedural memory was respectively detected with category exemplar generation and motor sequence tasks,and the declarative memory was assessed by free recall task.Results Compared with the controls,PI patients showed few correct numbers in the category exemplar generation (7.0 (6.0,8.8) vs 9.0 (9.0,11.0),Z=5.537,P＜0.01) and motor sequence task (8.0±3.3 vs 11.5 (8.6,13.8),Z=4.152,P＜ 0.01)and the phases of immediate recall (3.0 (2.3,4.0) vs 6.0 (5.0,7.0),Z =6.479,P ＜ 0.01),delayed recall (9.0 ± 2.2 vs 11.0 (10.0,12.0),Z =4.747,P ＜ 0.01) and delayed recognition (15.0 (13.0,15.0) vs 15.0 (15.0,15.0),Z=4.637,P＜0.01) of the free recall task.Furthermore,the early morning awakening group had significantly lower correct numbers in the motor sequence task,the delayed recall and recognition phases of the free recall task than the difficulty initiating and maintaining sleep groups.Conclusion The procedural and declarative memories are impaired in the PI patients,especially the early morning awakening insomniacs.
