OBJECTIVETo determine the differential diagnostic value of high molecular cytokeratin 34betaE12 as a benign marker in mammary lesions.

METHODS90 cases (30 benign non-proliferative diseases, 20 benign proliferative diseases, 10 intraductal carcinomas and 30 invasive carcinomas) were collected, all of which had undergone fine needle aspiration cytology (FNAC) examination and a follow-up operation. Immunohistochemical staining was performed using monoclonal antibodies against 34betaE12 on FNAC smears and the follow-up paraffin sections. SPSS 10.0 software was applied to analyze the differential diagnostic value of 34betaE12 in benign and malignant mammary lesions.

RESULTS(1) No significant difference was found in the expression of 34betaE12 between benign non-proliferative and proliferative disease. (2) A significant difference was found between the expression of 34betaE12 in mammary benign disease and mammary carcinoma. 66.7% and 66.3% of the carcinoma cases showed either lack of 34betaE12 expression or had only a few isolated 1+ cells which were cytoplasmic positive for 34betaE12 immunoreaction on FNAC smear and paraffin section respectively. The remaining 33% of cases having 2+ to 3+ cells mainly displayed cytoplasmic granular positive reaction rather than strong membranous and cytoplasmic positive reaction as benign lesions. In contrast with carcinoma, most benign lesions showed strong immunoreaction of 2+ to 3+ and especially exhibited complete strong membranous and cytoplasmic positive reaction on paraffin section, their positive expressive character differed from those of carcinoma. The positive rates on FNAC smear and paraffin section were 100% and 78% respectively. (3) Certain types of intraductal carcinoma, including low grade cribriform, papillary and solid type either lacked 34betaE12 expression or revealed a few isolated 1+ cells with cytoplasmic positivity for 34betaE12 immunoreaction. Pronounced immunoreaction of 3+ was only seen in high grade comedotype intraductal carcinoma.

CONCLUSIONS34betaE12 may serve as a marker of benign mammary disease for differential diagnosis. When there is a total or predominant lack of 34betaE12 expression, the possibility of carcinoma should be strongly considered. If 34betaE12 is expressed diffusely in the suspicious area with a strong membranous staining in particular, a benign proliferative process rather than carcinoma must be considered.

Objective To investigate the application technology and effect of Navien catheter in intracranial aneurysms embolization.Methods The clinical data of 15 patients with intracranial aneurysm treated with Navien catheter in Department of Neurosurgery of Yijishan Hospital Affiliated to Wannan Medical College from March to December 2016 were analyzed retrospectively. The extracranial segments of internal carotid arteries were seriously tortuous in all patients. The coaxial system was used during procedure. Whether the Navien catheter could be smoothly placed into the target artery or not was observed,and the coils or stent-assisted coils were used to embolize the intracranial aneurysms in the corresponding positions. The immediate embolization results were assessed by the Raymond grading. The intraoperative and postoperative complications were observed and the patients were followed up by imaging.Results All 15 patients had abnormal tortuosity of extracranial segments of internal carotid arteries. The Navien catheter was able to smoothly pass through the tortuous vessels and reach the desired position. The stent-assisted coil embolization was used in 9 patients,and the coil embolization was used in 6 patients. The success rate of the coil and stent placement technology was 100%. The stents were all accurately put in place without shift. According to the Raymond grading,the immediate embolization rate of aneurysms showed that 15 patients achieved Raymond gradeⅠ. One case developed internal carotid spasm during the procedure. The patient was improved after giving papaverine. Others did not have intraoperative complications,such as cerebral vasospasm,vascular dissection,in-stent thrombosis,and intraoperative aneurysm rupture. Five patients were followed up for 3 to 6 months with digital subtraction angiography (DSA). There was no recurrence of aneurysm and no in-stent stenosis and shift,No rebleeding or cerebral ischemia was observed.Conclusion Forpatients with severely tortuous in extracranial segments of internal carotid artery,using the Navien catheter may overcome artery tortuosity and other unfavorable factors of the patients and successfully reach the target vessel position,enable the embolization of intracranial aneurysms to be completed successfully.

OBJECTIVETo summarize the diagnostic features of fine needle aspiration cytology (FNAC) of myxoid lesions in soft tissue, and to define the cytological criteria for differentiating benign lesions from sarcomas and between various myxoid lesions.

METHODSFNAC data of 24 soft tissue myxoid lesions (14 benign lesions, 10 malignant lesions) from 1993 to 2006 from Kiang Wu Hospital, Macau were reviewed in correlation with the clinical course or the results of biopsy.

RESULTSGanglion, myxoma, and myxoid nodular fasciitis were the most common benign myxoid lesions of the soft tissues, all of which had low cellularity and lack of marked cellular atypia in smears in common. Ganglion was characterized by the disappearance of or the gradual minimization of the nodule after aspiration and the lack of blood vessel in smears. Myxoid nodular fasciitis was characterized by a pleomorphic pattern of proliferative cells and the presence of ganglion cell-like cells. Myxoid liposarcoma, extraskeletal myxoid chondrosarcoma and myxofibrosarcoma were the most common myxoid sarcomas. Cytologically, they had high cellularity and various degrees of cellular atypia. Myxoid liposarcoma exhibited branching chicken-wire like capillary vessels and/or lipoblasts; myxofibrosarcoma were prominent in both pleomorphic and atypia of the cells. The data revealed that the diagnostic accuracy of FNAC was nearly 100% in differentiating benign and malignant myxoid lesions of the soft tissues. The coordinate rate to the histopathology diagnosis of the common myxoid lesions of the soft tissues was above 75% (benign 71.4% and malignancy 80% respectively).

CONCLUSIONSFNAC is an effective method in diagnosing myxoid lesions of soft tissue, in correlation with the clinical data and the accessory examinations. FNAC can provide an objective basis for the treatment of myxoid lesions and prevention of unnecessary surgical operations.

OBJECTIVETo study the value of immunocytochemical study for cyclin D1, c-erbB-2, Ki-67, p21(CIP1/WAF1) and 34betaE12 in fine needle aspiration cytology (FNAC) diagnosis of mammary lesions.

METHODSOne hundred and thirty-five cases of breast diseases, all with FNAC performed and follow-up histologic correlation available, were enrolled into the study. These included 43 cases of benign non-proliferative diseases, 45 cases of benign proliferative diseases and 47 cases of mammary carcinoma. Immunostaining for cyclin D1, c-erbB-2, Ki-67, p21(CIP1/WAF1) and 34betaE12 was carried out on FNAC smears and paraffin sections of the corresponding biopsy specimens. The statistical significance was analyzed using SPSS11.5 software.

RESULTSNo statistically significant difference was observed in the expression of cyclin D1, c-erbB-2, Ki-67, p21(CIP1/WAF1) and 34betaE12 within the groups of benign non-proliferative and benign proliferative breast diseases. On the other hand, a significant difference in immunostaining results was found between benign breast lesions and mammary carcinoma (P < 0.001). A panel of cyclin D1, 34betaE12 and c-erbB-2 immunostaining is highly sensitive and specific in confirming the diagnosis of mammary carcinoma in FNAC samples. A positive reaction for cyclin D1 and c-erbB-2, when coupled with a negative reaction for 34betaE12, showed to be the most reliable supportive evidence for the malignant cytologic diagnosis. When taking the results of either cyclin D1 or 34betaE12 immunostaining into consideration, the sensitivity and specificity for diagnosing carcinoma was 95.7% and 94.3% respectively. On the other hand, when any of the three immunostains suggested carcinoma, the diagnostic sensitivity and specificity became 97.9% and 92.0% respectively. If the immunostaining results of any two of the three markers suggested carcinoma, the diagnostic sensitivity and specificity became 72.3% and 100% respectively. Within the carcinoma group, the degree of expression of cyclin D1, p21(CIP1/WAF1) and 34betaE12 showed little difference amongst different cytologic grades (according to Robinson cytologic grading system). There were however differences in expression of c-erbB-2 and Ki-67. Highest expression rate was observed in grade 3 carcinoma, while lowest expression rate was observed in grade 1 carcinoma (only in 40.0% and 33.3% of cases respectively). Whenever either cyclin D1 positivity or 34betaE12 negativity was demonstrated, the diagnostic accuracy for grade 1 and grade 2 carcinoma was 93.3% and 96.2 % respectively.

CONCLUSIONSImmunocytochemical study using a panel of antibodies for cyclin D1, c-erbB-2, and 34betaE12 has significant diagnostic value in distinguishing between benign breast diseases and mammary carcinoma in FNAC samples. Cyclin D1 and 34betaE12 are especially useful in confirming the cytologic diagnosis of low-grade cancer.

Objective To investigate the feasibility and effectiveness of endovascular treatment of posterior communicating artery aneurysm (PcoAA)in keeping the fetal posterior cerebral artery (FPCA) patency. Methods Form January 2014 to December 2015,14 patients with ruptured PcoAA enrolled retrospectively were treated with endovascular embolization. Six of them were treated with simple coil embolization,3 with stent-assisted coil embolization,3 with double catheter-assisted coil embolization,1 with stent-assisted coil embolization + double catheter technique,and 1 with Y-stent in Yijishan Hospital, Wannan Medical College. The immediate embolization rate of PcoAA (using Raymond grade),prognosis of the patients (the modified Rankin scale score at 6 months after procedure),complications,and imaging follow-up results were analyzed. Results The success rate of coil and stenting was 100% . All the stents were accurately released in place without displacement. The immediate Raymond grading of the aneurysms displayed that Raymond grade Ⅰ was in 8 cases,Raymond grade Ⅱ was in 4 cases,and Raymond grade Ⅲ was in 2 cases. All FPCA were kept patent. A coil protruded into internal carotid artery in one case during the procedure. Others did not have any complications,such as intraoperative cerebral vasospasm,in-stent thrombosis,and rupture. All 14 patients were followed up for 3 -24 months after procedure. Two had recurrence. Both were aneurysms embolized with coils only. No rebleeding and ischemic
complications were observed. The modified Rankin scale scores in 13 cases were 0 -2 at 6 months after procedure,1 was 4. Conclusions Endovascular embolization for the treatment of PcoAA and keeping FPCA patency are safe and feasible. A variety of endovascular treatment modalities are necessary in order to keep FPCA patency.

Objective To investigate the risk factors for influencing recrudescence after endovascular embolization of posterior communicating artery aneurysms.Methods From January 2014 to December 2014,71 consecutive patients (a total of 74 aneurysms) with posterior communicating artery aneurysm treated with endovascular treatment at the Department of Neurosurgery,Yijishan Hosptial of Wannan Medical College were enrolled retrospectively.The aneurysms were calculated as the number of cases (n=74).The aneurysms were divided into two groups according to whether they had recrudescence or not,including recurrent group (n=18) and non-recurrent group (n=56).The differences of the clinical data and aneurysm characteristics between the two groups were compared.Multivariate logistic regression was used to analyze the risk factors for recrudescence after endovascular embolization of posterior communicating artery aneurysms.Results Of the 74 patients with aneurysm,51 were treated with simple coil embolization and 23 were treated with stent-assisted coil embolization.All the coils were released satisfactorily.There were significant difference in the size of aneurysms and Raymond grade between the two groups (all P<0.01).The incidence of aneurysms with daughter cysts (55.6% [10/18] and the rate of non-stent-assisted coil embolization (88.9% [16/18]) in the recurrent group were significantly higher than those in the non-recurrent group (23.2% [13/56],62.5% [35/56]).The difference between the two groups was statistically significant (all P<0.05).There was no significant difference in other aneurysm features between the two groups (all P>0.05).After variable selection,the Raymond grade was referred to Raymond gradeⅠ.Multivariate logistic regression analysis showed that the non-stent-assisted coil embolization (OR,4.789,95%CI 1.207-19.009,P=0.026),Raymond grade Ⅱ (OR,12.326,95%CI 3.838-39.592,P<0.01),Raymond grade Ⅲ (OR,36.884,95%CI 2.892-470.454,P=0.005) were the independent risk factors for recrudescence after embolization of posterior communicating artery aneurysms.Conclusion Non-stent-assisted coil embolization,Raymond Ⅱ and Ⅲ may cause recrudescence of posterior communicating artery aneurysms.
