Ankle-brachium index and Doppler alterations were observed before operation and 30 days after operation. Results showed that, the ankle-brachium index and circulation state of Doppler had significantly increased at 30 days after operation compared to before operation (P

Objective To investigate the diagnosis value of p16 combined with Ki67 protein in cervical lesions.Methods Totally 1 542 women with previous liquid-based cytology smear result of abnormality underwent a colposcopy-directed biopsy excision procedure.Biopsy specimens were detected by p16 and Ki67 immunostaining alongside hematoxylin and eosin (H&E) staining.A four-semiquantitative class was used to describe the immunohistochemical results.Results Biopsy results revealed 1 542 women included 473 women with negative for dysplasia (NEG),629 women with cervical intraepithelial neoplasia (CIN) Ⅰ,206 women with CIN Ⅱ,206 women with CINⅢ and 28 women with cervical squamous cell carcinoma (SCC).The averageage of this study population was 34.47 years.CINs mainly occurred in women aged 20-29 years and 30-39 years.The positive rates of p16 in NEG,CIN Ⅰ,CIN Ⅱ,CINⅢ and SCC were 15.22％,60.25％,98.06％,99.51％,100.00％ respectively,and the positive rates of Ki67 were 12.05％,63.12％,96.12％,98.06％,100.00％ respectively.p16 expression and Ki-67 expression significantly increased with disease progression (p16:r =0.758,P =0.000 ; Ki67:r =0.773,P =0.000).Expression level of p16 was positively related with Ki-67 (r =0.774,P =0.000).The positive expression rates of p16 and Ki-67 of NEG were significantly lower than those of CIN and SCC (p16:x2 =1 127.46,P =0.000;Ki67:x2 =1 316.85,P =0.000).The positive expression rates of p16 and Ki-67 were markedly higher in CIN Ⅰ than those in CINⅡ,CINⅢⅢ and SCC (p16:x2 =500.19,P =0.000;Ki67:x2 =603.23,P=0.000).Conclusion Women aged 20-39 years are key subjects for cervical cancer screening.p16 and Ki67 immunohistochemistry is important in the ancillary diagnosis of cervical lesions.

OBJECTIVETo investigate the autopsy characteristics, pathologic type, malfomation and genetic characteristics of complete atrioventricular septal defect (CAVSD).

METHODSThirty five cases of CAVSD were collected from Maternal and Child Hospital of Haidian District during Jan.2003 to Jan.2015. Autoptic material, clinical history and chromosome examination were reviewed.

RESULTSAmong 35 cases of CAVSD between 18-38 gestational weeks, there were 26 cases with CAVSD A (74.3%, 26/35), 1 case with CAVSD B (2.8%, 1/35) and 8 cases with CAVSD C (22.8%, 8/35). Only CAVSD malformation was seen in 4 cases (11.4%, 4/35). Multiple malformations were seen in 31 cases (88.6%, 31/35). Combined malformations most frequently occurred in cardiovascular, respiratory and locomotor system. Among 15 cases with chromosome examination, chromosome aberrations was found in 13 cases (13/15) and trisomy-21 was found in 11 cases (11/15).

CONCLUSIONSCAVSD is a rare disease and CAVSD A is the most common type. CAVSD is usually combined with other malformations and chromosome aberrations.

OBJECTIVETo study the expression and clinicopathologic significance of cancer stem cell markers CD44v6 and CD24 in ovarian serous carcinoma tissues.

METHODSOne hundred and two cases of ovarian carcinoma diagnosed during the period from June, 2001 to December, 2010 were retrieved from archival files. The histology slides were reviewed and a two-tier system for grading of ovarian serous carcinoma was applied. The expression of CD44v6 and CD24 was detected by immunohistochemistry using EnVision method. The relationship between CD44v6/CD24 expression and various clinicopathologic parameters was analyzed.

RESULTSThere were 46.1% (47/102) and 59.8% (61/102) cases expressing CD44v6 and CD24, respectively. Both CD44v6 and CD24 expression showed positive correlation with higher histopathologic grade (P = 0.003 and P < 0.05, respectively). CD24 expression also correlated with the presence of lymph node metastasis (P < 0.05). There was no statistically significant relationship between the expression of these two markers (χ(2) = 0.394, P = 0.530). The age of the patients, histopathologic grade, clinical stage and nodal status correlated with progression-free survival time (P < 0.05). CD44v6 expression and histopathologic grade correlated with the overall survival time (P < 0.05). Patient age was an independent poor prognostic factor by multivariate analysis.

CONCLUSIONSCD44v6 expression, age older than 50 years, high clinical stage and presence of lymph node metastasis are associated with poor prognosis in patients with ovarian serous carcinoma. The two-tier system for grading of ovarian serous carcinoma is useful in predicting survival; and high tumor grade represents an important poor prognostic indicator for ovarian serous carcinoma.

Objective To investigate the effect of genetic factors on the occurrence of chronic post-thoracotomy pain syndrome ( PTPS) from the perspective of genetic polymorphisms. Methods Two hun-dred patients of both sexes, of American Society of Anesthesiologists physical statusⅠ or Ⅱ, aged 18-80 yr, scheduled for elective video-assisted thoracoscopic radical lung cancer surgery, were enrolled in this study. Blood samples were taken before operation for genotype analysis of 20 SNP loci, such as rs4073 and rs3774932, after DNA extraction. Postoperative multimodal analgesia was applied to maintain the visual an-alogue scale score ＜3. All the patients were followed up for 2-4 months after operation to record the occur-rence of PTPS. The patients were divided into 2 groups according to whether PTPS occurred: non-PTPS group (group N) and PTPS group (group P). Results The incidence of PTPS was 38. 7％ after surgery, and there were 114 patients in group N and 72 cases in group P . There was significant difference in A/T al-lele and genotype frequency at interleukin-8 rs4073 site and NF-κB1 rs3774932 site between the two groups (P＜0. 05). Conclusion Interleukin-8 and NF-kappa B1 genetic polymorphisms are associated with the occurrence of PTPS.

Objective To study the etiology, pathogenesis, clinicopathologic characteristics, prognosis and treatment of congenital pulmonary airway malformation (CPAM).Methods Eighteen cases of CPAM were enrolled into the study.The clinical history, autopsy findings and immunohistochemical results were evaluated, with review of literature.The pathogenetic mechanism, pathologic features and differential diagnosis of CPAM were studied.Results Histologic examination showed that 2 cases were classified as Stocker typeⅠ, 12 cases as type Ⅱ, and 4 cases as type Ⅲ.The lesion was unilateral and involved single lobe in 13 cases.The remaining 5 cases had bilateral diseases.Of the 18 cases studied, 12 cases showed single organ involvement and 6 cases had malformations affecting multiple organs.The associated malformations included cardiac anomalies ( 4 cases ) , polycystic kidney with gastrointestinal atresia (1 case) and nuchal cystic hygroma with hydrothorax (1 case).Conclusions CPAM is a rare pulmonary disorder.The etiology of this non-neoplastic condition is unknown.Imaging analysis is a valuable tool to suggest CPAM, while definite diagnosis requires pathologic examination.The overall prognosis is determined by the presence of associated malformations, fetal hydrops and pulmonary hypoplasia.

OBJECTIVETo study the pathogenesis, pathologic features and prognosis of fetal nuchal cystic hygroma.

METHODSForty autopsied cases of fetal nuchal cystic hygroma were collected during January 2003 to December 2012. The clinical history, pathologic changes and immunohistochemical (EnVision method) findings were reviewed, and the pathogenesis and pathologic characteristics were analyzed.

RESULTSOf the 40 cases, 16 (40.0%) showed single malformation and 24 (60.0%) were associated with multiple malformations in other organs and/or systems.Nineteen cases were septated and 21 were not. The associated malformations occurred in the respiratory system, skeletal system and urinary system.In the cases of combined malformations of umbilical cord, 3 were single umbilical artery malformations and 1 was torsion and stricture of umbilical cord.Four cases had chromosomal analysis, and all were trisomy-21.

CONCLUSIONSFetal nuchal cystic hygroma is a rare disease. The etiology is unknown, but it is not neoplastic.Lymphangioma is divided into 3 types:capillary lymphangioma, cavernous lymphangioma and cystic hygroma according to their expansile growth pattern. The overall prognosis is determined by any co-existing chromosomal anomalies, associated malformations and the time of diagnosis of the cystic hygroma.
