Objective To study the clinical characteristics, diagnosis, treatment and its effectiveness of vulvar intraepithelial neoplasm Ⅲ(VIN Ⅲ).Methods Clinical data, including age of the patients, mode of surgical operation, pathological features, results of post-operation follow-up, of 12 cases of VIN Ⅲ admitted to the Peking Union Medical College Hospital(PUMCH)during January 1984 to December2006 were retrospectively analyzed.Results Mean age of the 12 cases was 40.3(ranging from 23 to 56)years.All the patients had symptoms of vulvar itching, three with VUlVar ulcer and one with vulvar pain.There was single neoplasm focus in two cases and multiple focuses in 10 cases, five cases with neoplasm in other sites and five with human papilloma virus(HPV)infection.All the 12 patients received surgical operation, three with simple vulvectomy(one with some residue at perianal incisal edge)and other nine with lumpectomy(four with some residue at incisal edge).Eight cases were followed-up for 9.0 months in average(ranging 1～22 months)after surgical operation, including three with some residue at incisal edge.Relapse was found in two cases three and 11 months after operation, respectively, who received re-operation, including one with residue at incisal edge and one without residue.Conclusions It is necessary to attach more importance to biopsy for the cases of suspected VIN Ⅲ, as well as colposcopic diagnosis for those with vaginal or vulvar neoplasm and testing for HPV infection.Surgical operation, including simple vulvectomy and lumpectomy with or without adjunctive measures, are main treatment for patients of VIN Ⅲ and follow-up is also important for all those with VIN Ⅲ.

ObjectiveTo investigate the effects of ABI-1 gene knockdown upon the proliferation and migration of human gastric cancer cell NCI-N87 in vitro. MethodsNCI-N87-ABI-I-ShRNA cell model was successfully constructed and validated by Real-time PCR and Western blot. The cellular morphous and skeleton, proliferative and migrative potents, and also AKT expression were compared between NCI-N87-ABI-1-ShRNA and its parents by immunofluorental staining, CCK-8 assay, transwell chamber and Western blotting.ResultsCCK-8 assay showed there was no significant difference in the proliferation rates at different time points between the NCI-N87-Vector and NCI-N87 cells while the proliferation rates at the time points of 36 and 48 hours of the NCI-N87-ABI-1-ShRNA were significantly lower than the NCI-N87( t =2. 85and 4. 166, P ＜ 0. 05 ). Transwell assay showed that migrated cell number were 66 ± 8, 65 ± 8 and 30 ± 4,respectively, and there was significant difference between the NCI-N87-ABI-1-ShRNA and NCI-N87 cells (t =9. 550,P ＜0. 05). Finally, ABI-1- knock-down altered the cellular morphoos and skeleton of 90％NCI-N87 cells and inhibited p-AKT expression.ConclusionABI-1 inhibits proliferation and migration of NCI-N87 cells in vitro probably by PI3K/AKT pathway.

Objective To explore the relationship between resilience and coping style of cardiac valvular postoperative patients with cardiopulmonary bypass.Methods A total of 208 cardiac valvular postoperative patients with cardiopulmonary bypass were recruited from 4 cardiovascular surgery in Guangdong and were investigated with the self-designed questionnaire,Connor-Davidson Resilience Scale (CD-RISC),Medical Coping Modes Questionnaire (MCMQ).Results The average score of resilience in cardiac valvular postoperative patients with cardiopulmonary bypass was (55.38±10.63)points.The average score of tenacity,strength and optimism were (28.21 ±5.87)points,(18.21 ±4.02)and (8.96± 1.85)points respectively.The average score of coping style of confrontation,avoidance and acceptance-resignation were(18.13±3.38),(16.95±1.75)and (9.24±2.47)points respectively.All the sub-scores of the resilience were positively correlated with confrontation,and all the sub-scores of the resilience were negatively correlated with avoidance and acceptance-resignation.Conclusions There is a certain degree of correlation between resilience and copping style of cardiac valvular postoperative patients with cardiopulmonary bypass.Nurses should enhance resilience of the patients,guide the patients to adopt effective coping styles,to promote disease rehabilitation and improve the quality of life.

Objective To investigate the value of the intraoperative real-time three-dimensional transesophageal echocardiography (RT 3D-TEE) in therapeutic application of surgery for the mitral valve prolapse.Methods Thirty-five patients underwent surgical treatment were diagnosed as mitral valve prolapse by 2-dimensional transthoracic echocardiography (2D-TTE),with or without ruptured chordae tendineae.RT 3D-TEE was performed for assessing the segment of prolapse and its complications before cardiopulmonary bypass and after heart resuscitation respectively.The echocardiographic results were compared with the surgical findings.Results The accuracy of RT 3D-TEE to identify segments with prolapse was significantly higher than that of 2D-TTE (91.4％ vs 82.9％,P =0.003).RT 3D-TEE was more accurate than 2D-TTE for identifying ruptured chordae tendineae,vegetation and thrombus since higher sensitivity,specificity and Youden index.Among all 35 patients,valvuloplasty was performed in 28 cases,whereas,only 7 cases underwent replacement of prosthetic valves.Three patients were benefited by accurate evaluation of therapeutic effect using RT 3D-TEE in time.ConclusionsIntraoperative RT 3D-TEE can be used to provide “ surgical view”,acquired adequate valuable information of mitral valve,and more reliable functional and anatomical assessment of the mitral valve components and its geometry.Suitable surgical intervention can be designed for improving outcomes of patients.

Objective To determine whether real-time three-dimensional transesophageal echocardiography(RT-3D TEE) is an accurate non-invasive technique for defining the morphology of atrial septal defects(ASD). Methods In 20 patients with secundum ASD, mean age 42.2 years (7 male, 13 female) ,live three dimensional surgical views of ASD were acquired,qualitative morphology of ASD such as the shape, presence of fenestrations and the defect margins were noted during the cardiac cycle. The measurements obtained from 2-dimensional transesophageal echocardiography(2D-TEE) and RT-3D TEE were compared to those obtained from stretched balloon diameter(SBD) or surgery. Measurements of the size and area change of ASD were validated during the cardiac cycle by RT-3D TEE,stepwise multiple linear regression analysis was performed to test the correlation between the maximum change ratios of area and diameter of ASD and age, atrial septal length, ASD shunting velocity, the maximum diameter of ASD and right ventricular systolic pressure. Results ① The morphology of ASD was circle-like or elliptical in systole,irregular or elliptical in diastole. ②The area and diameter of ASD measured by RT-3D TEE was minimal in isovolumetric contraction phase, maximal in isovolumetric diastole phase. The correlation coefficient of maximum diameter measured by 3D with SBD was 0.962 , greater than that by 2D and SBD (0.820). ③The change ratio of area and maximum diameter of ASD acquired by RT-3D-TEE was 11.48%-71.12% and 2.80%-43.87% respectively,and the correlation coefficient of them was 0.921. Conclusions RT-3D TEE using live 3D-Zoom mode accurately displayed the varying morphology,dimensions and spatial relations of ASD. RT-3D TEE can offer visualization morphological changing of ASD in different periods of cardiac cycle,providing more information for percutanous catheter intervention and open heart surgery.

Objective To evaluate the feasibility and accuracy of full volume three-dimensional echocardiography(FV3DE) for quantifying the left ventricular volume in healthy fetuses. Methods Two hundred and twenty-two normal fetuses with gestational ages between 20 and 40 weeks were investigated. Full volume three-dimensional, two-dimensional (2D) and M-mode images were acquired by Philips iE33 system and data was processed offline using QLAB analysis software. Left ventricular end-systolic volume(ESV) and end-diastolic volume ( EDV) were measured using semiautomated border detection echocardiographic techniques, and compared with 2D biplane Simpson's method and M-mode Teichholz formula. Results Thirty-six fetuses with poor three-dimensional images and 5 twin pregnancies were excluded,the study subjects consisted of 181 singleton fetuses. The highest concordance correlation ( r =0.987 for EDV, r =0.988 for ESV) P <0. 001) was noted between 2D biplane Simpson's and FV3DE-derived values with a small bias (0. 332 ml for EDV,0. 135 ml for ESV). The Bland-Altman analysis showed that FV3DE had the best reproducibility than M-mode Teichholz formula and 2D biplane Simpson's method. Intra- and interobserver error of EDV were 2.85% and 4.22% for FV3DE,8.37% and 8.98% for 2D biplane Simpson's rule,30. 63% and 54. 70% for M-mode Teichholz formula. Intra- and interobserver error of ESV were 2.34% and 6. 14% for FV3DE,6. 26% and 11.7% for 2D biplane Simpson's rule,43.06% and 66.03% for M-mode Teichholz formula. Conclusions FV3DE is a novel technique that can be more accurate than conventional methods in quantification of fetal left ventricular volumes, it may provide new insight into evolving fetal cardiac structure and function.
