Objective To explore enhanced MRI diagnostic value of CPA(cerebellopontine angle) tumors.Methods 68 cases of CPA tumors,including acoustic neuromas(n=34),trigeninal neuromas (n=5),meningiomas(n=20)and cholesteatomas(n=9),proved surgically and pathologically were studied.All patients were performed MR scans before and after contrasted-enhancement on axial,sagittal and coronal plane.Results 23 of 34 acoustic neuromas showed nodule-ring-like,wreathlike or mutilocular enhanced masses;11 were homogeneous masses.The facial-hearing nerve bundle were markedly thickened and enhanced in 34 cases and in which 15 presented "water-chestnut"sign;suggesting it was a typical appearance of acoustic neuromas.5 trigeminal neuromas manifested nodule-ring-like or multilocular enhanced masses(n=3),and dumbbell-like masses(n=2).20 meningiomas exhibited homogeneous massive enhancement,"dural tail"sign(n-11),the facial-hearing-nerve bundle on the affected side were enhanced but not thickened(n-5);which represented reactive changes to the tumors.9 cholesteatomas displayed long T 2 long T 1,no enhancement;spreaded along subarachnoid space and basilar artery encapsuled(n-5).Conclusion Enhanced MRI can reveal the characteristics of CPA tumors,it is of especial value for diagnosis of the tumors.

Objective To investigate the efficacy of TTC and FTC regimens as neoadjuvant chemotherapy in breast cancer. Methods Collecting clinical data of 325 patients received neoadjuvant chemotherapy with TIC and FTC regimens from June 2004 to April 2008, among them 138 patients received neoadjuvant chemotherapy with TTC regimen in one group, and 187 patients received neoadjuvant chemotherapy with CTF regimen in the other group. The expression of Topo Ⅱ a in specimen of 325 patients before neoadjuvant chemotherapy were detected by immunohistochemical method. Results Among the 325 cases of neoadjuvant chemotherapy, the overall response rate (RR) was 87.7 % in TIC arm and 67.4 % in FTC arm (P=0.000), but in the group of Topo Ⅱ a(+) Her-2(-), the overall response rate (RR) was 87.8 % in TTC arm and 79.4 % in FTC arm (P=0.266), and in the groups of Topo Ⅱ a(-), there was statistical significance; the pathologic complete response rate (pCR) was 13.7 % in TIC ann and 11.2 % in CTF ann (P=0.491). Conclusion TIC regimen is superior to FTC regimen in the response rate of neoadjuvant chemotherapy, but patients with negative expression of Topo Ⅱ a may get more benefits from 9eoadjuvant taxane and anthracycline chemotherapy.

Objective To study the imaging features of meningiomas of ethmoid sinuses. Methods Six cases of meningiomas of ethmoid sinuses verified pathologically were analyzed retrospectively. Results CT scans of 6 cases exhibited huge cystic masses ( n =3), huge cystic solid masses ( n =2), huge solid mass ( n =1). The cystic walls were remarkable osteosclerosis. The density of solid masses were homogeneous, or heterogeneous with calcifications and cystic changes, and prominent contrast enhancement. MR images of 1 case (1/6) showed a cystic solid mass, the cystic portion was highsignalintensity on T 2WI and lowsignalintensity on T 1WI, while the solid mass was isosignalintensity on T 1WI and T 2WI. The solid portion was enhanced. X ray plain films of 3 cases (3/6) displayed ethmoid sinuses enlargement and high density. Conclusion For the meningiomas of ethmoid sinuses, CT finding was specific, MRI was helpful in differential diagnosis, and X ray plain film was of no qualitative value.

Objective To summarize the outcome of treatment for thoracic vertebra ossification of ligamentum flavum (OLF)with en-bloc removal of the spinal canal’s posterior wall termed as the “thinned cap uncovering”technique.Methods From 2003 to 2013,56 patients with OLF were treated with thinned cap uncovering technique.In this group,there were 40 male patients and 1 6 female ones,with the average age of 45 years (range of 30-65 years)and the average history of 3 years.The 56 patients were followed up for an average duration of 2 years and 7 months (1-5 years).Results According to WANG’s evaluation,45 cases (about 80%) had excellent results,9 cases (about 1 6%)had good results,and 3 cases had improved symptoms,the excellence to good rates being 96%.Conclusion Removal of the posterior wall of the spinal canal via “thinned cap uncovering”technique is a reliable and effective treatment for thoracic OLF.The strategy for successful operation is to use high speed drill to cut bone accurately,which allows discectomy for thoracic vertebra and to diminish faults and complications during the surgical procedure.

Objective The aim of this study was to collect diagnosis,treatment,and follow-up information of inpatients with malignant tumors at the Affiliated Tumor Hospital of Xinjiang Medical University,analyze the distribution and composition of malignant tumor types,mortality,and survival status,and provide reference for the prevention and treatment of malignant tumors in the local area.Methods The case and mortality data of inpatients with malignant tumor from 2010 to 2020 were calculated,and the survival status was collected by follow-up.The composition,different pathological stage,composition and sequential changes of malignant tumors,as well as survival rates of the 1-year,3-year and 5-year were analyzed.Results A total of 111,418 patients with malig-nant tumor were admitted to the hospital from 2010 to 2020.Breast cancer accounted for 20.67％of inpatients,followed by lung canc-er,thyroid cancer,cervical cancer and gastric cancer;The leading cause of malignant tumor death was lung cancer(accounting for 26.70％),followed by gastric cancer,esophageal cancer,liver cancer and colorectal cancer.The 1-year,3-year,and 5-year sur-vival rates were 87.20％,65.80％and 57.20％,respectively.The overall survival rates of patients with stages Ⅰ and Ⅱ malignant tumors were significantly higher than those of patients with stages Ⅲ and Ⅳ(P=0.003).Conclusion Breast cancer,lung cancer,thyroid cancer,cervical cancer and gastric cancer are the high incidence of malignant tumors in Xinjiang,among which thyroid cancer,breast cancer,and cervical cancer have a higher 5-year survival rate.Early screening,diagnosis and treatment of malignant tumors should be strengthened,and prevention strategies and resource allocation should be adjusted in time according to the distribution of malignant tumors to reduce the incidence and mortality of malignant tumor and improve the health level of people in Xinjiang.
