Objective The aim of this study was to evaluate the effect of marriage quality intervention in peer education model among women with breast cancer.Methods Marginal quality questionnaire was used to assess in the intervention and control groups during the perioperative period.There had 120 breast cancer patients in the intervention group and 135 normal subjects for control group.The patients were followed by the peer education model and the marriage and quality education during the chemotherapy period.The marriage quality questionnaires were carried out one year after the operation.Results Marital satisfaction(38.73±7.45),couples communication(38.12±7.03)and sex life(36.77±6.96)were significantly higher than those of the patients who participated in the traditional health education group after 1 year of operation.The control subjects with traditional health education had lower satisfaction of marital life(32.59±9.29),husband and wife communication(34.41±7.39)and sexual life(32.59±6.59)in one year after surgery(P<0.001).The scores of marital satisfaction,husband and wife communication,and sex scores were significantly lower in patients with traditional health education after 1 year of operation(P<0.001).Conclusion Marriage quality interventions in the peer education model can effectively affect the marital quality of postoperative patients with breast cancer.

Background Acanthamoeba keratitis is a sort of serious infectious eye disease with high causing-blindness rate.Acanthamoeba keratitis often is misdiagnosed as fungal keratitis or viral keratitis in the early stage.Because conventional clinical diagnosis methods show a low specificity and take a long time,timely treatment often is delayed.Conventional PCR does not apply well because the lesion sample is not enough to extract DNA.However,direct PCR can amplify 18S rRNA conserved sequence of acanthamoeba keratitis without the extraction of DNA.Objective This study was to discuss the feasibility for rapid diagnosis of acanthamoeba keratitis using direct PCR to amplify the gene 18S rRNA fragment.Methods Ten acanthamoeba strains were isolated from 10 eyes with acanthamoeba keratitis in Qingdao Eye Hospital.The sensitivity of the direct PCR assay was tested using different numbers of amoebas.The specificity of the assay was tested using DNA extracted from acanthamoeba,candida albicans,pseudomonas aeruginosa,herpes simplex virus-1 (HSV-1) and normal human corneal epithelial cell.Acanthamoeba keratitis models were established using infected method in clean 6-week-old female BALB/c mice.Corneal lesion samples were obtained 1 day,3,5,7,10,15 days after modeled.The effectivity and feasibility of the direct PCR assay for rapid diagnosis of acanthamoeba keratitis were evaluated and compared with culture method,corneal smear examination and real-time PCR.Results Direct PCR primers could only amplify DNA of acanthamoeba rather than other pathogens,and 10 stains of acanthamoeba were detected at least in each sample.During the development of acanthamoeba keratitis in the mice,the diagnosis positive rate of direct PCR was 80.0％,90.0％,80.0％,70.0％,70.0％ and 50.0％ in 1 day,3,5,7,10,15 days after modeled with the total positive rate 73.3％,which was higher than 31.7％ of culture method,56.7％ of corneal smear examination and 61.7％ of realtime PCR,with a significant difference between the direct PCR and culture method (P =0.005),but no significant difference was seen in the total positive rate between the direct PCR and real-time PC R (P =0.172) or corneal smear examination (P =0.056).Conclusions The direct PCR assay is a simple,rapid,highly specific and sensitive method for the rapid diagnosis of acanthamoeba keratitis,especially for the limited lesion sample.

The epitope-G1 gene of Bovine ephemeral fever virus (BEFV) glycoprotein was synthesised by PCR and cloned into expression vector pPIC9K to construct recombinant plasmid pPIC9K-G1. Then the pPIC9K-G1 was linearized and transformed into Pichia pastoris GS 115. The recombinant P. pastoris strains were selected by a G418 transformation screen and confirmed by PCR. After being induced with methanol, an expressed protein with 26 kDa molecular weight was obtained, which was much bigger than the predicted size (15.54 kDa). Deglycosylation analysis indicated the recombinant G1 was glycosylated. Western blot and ELISA tests, as well as rabbit immunization and specificity experiments indicated that the target protein had both higher reaction activity and higher immunocompetence and specificity. The recombinant G1 protein could be used as a coating antigen to develop an ELISA kit for bovine ephemeral fever diagnosis.

Objective To investigate the relationship between carotid atherosclerotic plaque and multiple risk factors of angiocardiopathy,and to evaluate the injuries caused by different risk factors to subclinical target organ to control the general risk factors of angiocardiopathy.Methods Four hundred and twenty six outpatients and impatients,treated in our hospital from May 2007 to May 2009 with the results of color ultrasonic examination,were divided into carotid atherosclerotic plaque group(284 cases) and no carotid atherosclerotic plaque group( 142 cases).The clinical information including their age,body mass index,smoking condition,past medical history such as hypertension,diabetes mellitus and hyperlipoidemia were recorded,and the levels of total cholesterol(T C),high density lipoprotein cholesterol( HDL-C),low density lipoprotein cholesterol(LDL-C),triglyceride (TG),lipoprotein ( a ) ( LP (a) ),apolipoprotein A - 1 ( Apo A 1 ),apolipoprotein B ( Apo B ),highsensitivity C-reactive protein( hs-CRP),homocysteine ( HCY),microalbuminuria( MAU ) and uricacid(UA) were determined by lab tests.The independent variable and univariable data were processed and analyzed statistically to find out the risk factors of carotid atherosclerotic plaque.Results Age and drinking were significantly correlated with the carotid intima-media wall thickening(IMT) (P ＜ 0.001 ).Overweight,diabetes mellitus,increased LP (a),hyperlipoidemia,age,increased MAU and HCY could independently predict carotid atherosclerosis and plaque formation ( x2 =71.35,38.45,t =3.26,x2 =37.23,t =118.51,6.723 and 3.17respectively,Ps ＜ 0.05 ).The aggregated number of the risk factors was correlated to IMT and carotid atherosclerotic plaque ( P =0.0001 ).Conclusion Age,drinking,overweight,diabetes mellitus,increased LP (a),hyperlipoidemia,MAU and HCY are risk factors of carotid atherosclerosis and plaque formation,and the contribution of each factor can multiply and overlap,more risk factors means greater risk.
