ObjectiveTo discuss effective measures to improve postoperative sexual life quality of patients with cervical intraepithelial neoplasia (CIN).MethodsOne hundred and twenty patients with CIN were randomly assigned to the blue-ribbon club group, the friendship-support group and the control group. The blue-ribbon club patients were regarded as club members and received special education every two months. The friendship-support group patients received education one by one in the hospital setting and the control group patients received the same education as before participated into the trial. Female sexual function index (FSFI)was used to evaluate sexual function before and 6 months after intervention.ResultsExcept sexual pain, the total score of FSFI and the score of sub-domain in the blueribbon club were significantly higher than that in the control group. The total score of FSFI and score of sub-domain were significantly higher than that in the control group. There were no significant differences between both intervention groups.ConclusionsBoth education intervention modes of the blue-ribbon club group and the friendship- support group could effectively improve sexual function for post-operation patients with CIN.

Objective To study the expression of P57kip2 and its clinical significance in hilar bile duct adenocarcinoma.Methods The expressions of P57kip2 in hilar bile duct adenocarcinoma tissues (37 cases) and normal bile duct tissues (32 cases) were determined by immunohistochemical SP methods.The relations between the expression levels of P57kip2 with clinicopathologic parameters were analyzed.Results The positive rate of P57kip2 was 43.2％ (16/37) in bile duct adenocarcinoma,while it was 87.5％ (28/32) in normal duct tissues (P ＜0.01).The expression level of P57kip2 in adenocarcinoma showed no significant association with gender,age or CA19-9 level (P ＞0.05),but they were significantly related with lymph node metastasis,invasion and degree of differentiation (P ＜ 0.05).Conclusions P57kip2 is associated with the occurrence and development of hilar bile duct adenocarcinoma.It may play an important role in invasion and metastasis of hilar bile duct adenocarcinoma.The P57 protein can be used as an index to diagnose hilar bile duct adenocarcinoma.

Objective To investigate the effects of different culture media and pretreatment methods on the results of matrix-assisted laser desorption ionization time-of-flight mass spectrometry(MALDI-TOF MS) for the identification of Vibrio parahaemolyticus,and then provide the optimal conditions.Methods Forty strains of Vibrio parahaemolyticus were collected,and subcultured with the blood agar plate,thiosulfate citrate bile salts sucrose(TCBS) agar plate and double wash agar plate,respectively.The pretreatment methods before mass spectrometry included the smear method,extension method and extraction method.The effects of different culture media and pretreatment methods on the results of MALDI-TOF MS for the identification of Vibrio parahaemolyticus were analyzed by the logistics regression model and Chi-square test of SAS software.Results The detection rate of Vibrio parahaemolyticus was the highest in the combination of blood agar plate with the extraction method(genus level:100％;species level:67.5％),followed by the combination of double wash agar plate with the extraction method(genus level:70％;species level:37.5％).For the genus identification level of Vibrio parahaemolyticus,when the pretreatment method was the same,different culture media produced significantly different detection rates(P ＜ 0.01).However,when the culture medium was the same,there was no significant difference in detection rates for different pretreatment methods (P ＞ 0.05).The odd ratios (OR) of the smear method and extention method relative to the extraction method were 0.66 and 0.95,respectively,and there was no significant difference in detection rates for them(P ＞ 0.05),while the ORs of the TCBS agar plate and double wash agar plate relative to blood agar plate were 0.06 and 0.10,respectively,and there was significant difference in detection rates for them(P ＜0.05).The logistic regression equation was Y=2.95-0.41a-0.05b-2.83c-2.83d(a:smear method;b:extension method;c:TCBS agar plate;d:double wash agar plate).For the species identification level of Vibrio parahaemolyticus,when the extension method or the extraction method was used,different culture media produced significantly different detection rates(P ＜ 0.05).When the blood agar plate was used,different pretreatment methods also produced significantly different detection rates(P ＜ 0.01).The ORs of the smear method and extention method relative to the extraction method were 0.32 and 0.55,respectively,and there was significant difference in detection rates for them (P ＜ 0.05),while the ORs of the TCBS agar plate and double wash agar plate relative to blood agar plate were 0.18 and 0.49,respectively,and there was significant difference in detection rates for them(P ＜0.05).The logistic regression equation was Y =0.20-1.15a-0.61b-1.72c-1.72d(a:smear method;b:extension method;c:TCBS agar plate;d:double wash agar plate).Conclusion For improving the detection rate of Vibrio parahaemolyticus by MALDI-TOF MS,the selection of appropriate culture medium is more important than that of the pretreatment method.It is recommended that the extraction method may be as a conventional pretreatment method,and that the optimal medium is the blood agar plate,followed by the double wash agar plate and TCBS agar plate.

BACKGROUND: The degree of neurofilament (NF) phosphorylation is closely correlated with the occurrence of Alzheimer disease (AD), and apolipoprotein E4 (apoE4) is a generally acknowledged liability factor for AD, but the effect and mechanism of apoE4 on the NF phosphorylation in neurons are not very clear. It has been reported that in the neurons cultured in vitro and in brain tissue of AD patients, the amino acid residues of apoE4 protein C terminal (272-299) could be truncated by hydrolysis,and produce truncated-apoE4 fragment. The latter interacts with the NF phosphorylation in neurofibrillary tangles (NFTs), which are the characteristic pathological changes of AD.OBJECTIVE: To observe the effect of truncated-apoE4 overexpression on the NF phosphorylation in the cultured neurons.DESIGN: A non-randomized controlled observation.SETTING: Department of Biochemistry and Molecular Biology, School of Basic Medical Sciences, Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: The experiment was carried out in the Laboratory of Biochemistry and Molecular Biology, Tongji Medical College, Huazhong University of Science and Technology in December 2005. The mice neuroma cell strain N2a was provided by Dr. Xu.METHODS: The truncated-apoE4(△272-299) cDNA was subcloned into pEGFP-c3 to form pEGFP-T-apoE4 recombinant. Then pEGFP-c3, pEGFP-apoE4 and pEGFP-T-apoE4 were transfected into N2a cells by lipofectamine2000 respectively. NF phosphorylation was detected by Western blot assay. The activities of glycogen synthase kinase-3 (GSK-3) and cyclin-dependent kinase 5(CDK-5) were measured.MAIN OUTCOME MEASURES: The degree of NF phosphorylation and the activities of GSK-3 and CDK-5 were mainly observed.RESULTS: In the transfected groups, the contents of phosphorylated NF were significantly increased, the GSK-3 activities were significantly increased, which were the most significant in the pEGFP-T-apoE4 transfected group (P＜0.05), but the CDK-5 activities were not significantly different from that in th e control group (P＞0.05).CONCLUSION: These results indicate that in vitro overexpression of truncated-apoE4(△272-299) can lead to NF hyperphosphorylation by activating of GSK-3 but not CDK-5, which may be the underline mechanism of AD induced by truncated-apoE4(△272-299).
