Ameloblastic fibroma (AF) is a benign tumor, it is a true mixed tumor composed of neoplastic epithelium and mesenchymal. This tumor is rare, and it almost arises in the mandible. A 22-years old female patient referred AF in the maxillary was present. The tumor was asymptomatic, except the right facial bulge. The radiograph showed a well-circumscribed neoplasm with several low density cysts involving the right maxillary and ethmoid. The lesion was enucleated and the material was sent for histopathologic examination. Microscopically, it was composed epithelium and mesenchymal with histopathological diagnosis of ameloblastic fibroma.

Objective To investigate the efifcacy of thalidomide combined with VAD in treatment of elderly multiple myeloma(MM). Methods 76 cases of elderly MM were randomly divided into two groups, control group (n=38) were treated with VAD alone while the observation group (n=38) were treated with thalidomide and VAD. Clinical efifcacy and adverse reactions in two groups were compared. Results The total effective rate in observation group was 84.21%, which was signiifcantly higher than 55.26%in control group (P<0.05). After treatment, the M protein, myeloma cells andβ2-microglobulin in observation group were (20.77±4.15)×10-2μg/mL, (12.84±2.85)×10-2μg/mL and (2.48±0.53)μg/mL, which were signiifcantly lower than before treatment and control group(P<0.05). Hemoglobin in observation group was (108.83±5.81) g/L, which was signiifcantly higher than before treatment and control group(P<0.05). The adverse reactions were nausea, vomiting, drowsiness, constipation, infection and rash and so on in two groups after treatment, and there was no signiifcant difference between two groups. Conclusion Thalidomide combined with VAD regimen has a better effect in treatment of elderly multiple myeloma than single VAD, has less adverse reactions and well tolerated.

Objective To observe the influences of different anesthesia methods or adjuvant chemotherapy on hemorheological parameters in patients with cervical cancer.Methods Sixty pa-tients with cervical cancer were equally randomized into two groups.Patients in group A received three courses of chemotherapy preoperatively while those in group B did not.The patients of group A and B were divided respectively into two subgroups,combined epidural general anesthesia group (groups A1 and B1),general anesthesia group (group A2 and B2).Blood samples were taken for the hemorheological measurement at 5 min before induction of anesthesia,60 min after induction of anes-thesia and at the end of surgery.Results Red cell deformability index (EDI)was significantly lower in group A than that in group B;Erythrocyte rigidity index (ERI)and blood viscosity were higher in group A compared with those in group B (P <0.05).In groups A1 and B1,EDI,plasmic viscosity packed ERI,and ERI were all lower than those before anesthesia induction (P < 0.01 );while in groups A2 and B2 Hct decreased.Conclusion The patients of cervical cancer after chemotherapy showed some hemorheological changes characterized by a lowered EDI.Combined general and epidural anesthesia can significantly improve the above parameters.

Objective To evaluate clinical use of adaptive statistical iterative reconstruction (ASiR) method in low-dose scan on children temporal bone by comparison of radiation dose delivered by GE Discovert HD CT 750 scan and GE Lightspeed VCT64 scan.Method Sixty patients with congenital deafness were divided into two groups according to gender,age (each N =30).Group a received low-dose CT scan on temporal bone by GE Discovery HDCT 750 (preset NI =12),and the original images were reconstructed with ASiR (weighted value =40％).Group B received CT scan by GE Lightspeed VCT 64 (preset NI =8),and the original images were reconstructed with filter back projection (FBP).Data were collected and analysed using the SPSS 18.0 software.Resultes The mean value of electric current of average tube and CTDIvol were significantly different between group A and B [(110.40 ± 21.72) mA vs.(168.56±24.36) mA,and (26.43 ±3.48) mGy vs.(39.66 ±4.17) mGy,respectively (t=-9.76,-3.31,P＜0.05)].The noise index was (33.13 ±2.68) in group A and (33.79 ±2.93) in group B respectively,and the results had no statistical significance (P ＞ 0.05).Subjective scores of the images were (4.06 ± 0.03) and (4.05 ± 0.03),with no statistical significance either (P ＞ 0.05).Conclusions On a condition of achieving same image quality,CT scan program using GE Discovery HD CT 750 with 40％ ASiR reconstruction and 4 units NI value enhancement could effectively reduce radiation dose on children's temporal bone compared to FBP method using GE Lightspeed VCT 64.

Objective To investigate the clinical effect of super selective embolization combined with opera-tion for treatment of meningiomas.Methods 82 cases treated by operation and pathology in return for meningioma were collected in the study,including 44 cases of preoperative superselective embolization for aneurysms as the treat-ment group,and the remaining 38 cases without preoperative embolization of patients as the control group.The opera-tion time,bleeding amount in the operation and the rate of total tumor removal were recorded and compared between the two groups.Results The average amount of bleeding of treatment group was (330.36 ±95.41)mL.The average amount of bleeding of control group was (460.82 ±114.64)mL.The data of the two groups was statistically significant (t =5.624,P <0.01).,The treatment group bleeding amount was less than that of the control group;,the mean oper-ation time of treatment group was (5.36 ±2.62)h,,the average operation time of control group was (6.63 ±2.25)h.The data of the two groups was statistically significant (t =2.355,P =0.021 ),the operation time of the treatment group was less than that of the control group.The total resection rate was 70.4% in treatment group and 36.8% in the control group,there was statistically significant (P <0.05),and the total resection rate in the treatment group was higher than that in the control group.Conclusion Compared with single operation treatment of meningiomas superse-lective embolization combined with operation for treatment of meningiomas can shorten operation time,reduce intraoperative hemorrhage,improve the rate of total tumor removal.It can reduce the operation risk and improve the treatment effect.

Objective To evaluate the influence of diabetes on cancer stage,treatment,and overall survival rate among newly diagnosed cancer patients,and the correlation between diabetes mellitus and cancer.Methods Total 16 890 newly diagnosed cancer patients were analyzed retrospectively.Morbidity rate of diabetes mellitus,stage of cancer,cancer treatment,survival rate,and comorbidities were collected and compared.Results 9.57% of those 16 890 cancer patients were suffering from diabetes by the time of cancer diagnosis.The prevalence of diabetes was high among patients with pancreas cancer (18.76%),renal cancer (16.76%),colorectal cancer (12.34%),and uterine cancer (10.97%).Colorectal cancer was often diagnosed at an advanced tumor stage.Compared with those without diabetes,diabetic patients with colorectal cancer,gastric cancer,and endometrial carcinoma were more likely to receive surgical treatment.Unadjusted analyses showed that the median survival time and percent alive at 3 years in cancer patients with diabetes were significantly reduced in all types of cancers,except for prostate cancer,as compared with those cases without diabetes.After adjustment for occurrence of cardiovascular disease,diabetic patients with colorectal,breast,endometrial,ovary,prostate,kidney,and lung cancers still had a 8%-55% increased risk of mortality compared to cancer patients without diabetes mellitus (P＜0.05).Conclusion The prevalane of cancer in diabetes is higher than non-diabetics.Diabetic cancer patients are frequently treated less aggressively and have a worse prognosis compared to those without diabetes.

Obiective To study the regularity of three-dimensional displacement in respiration of lung cancer. Methods Af-ter CT scanning, the CT images were transferred into target planning system (TPS) to obtain three-dimensional reconstruc-tion images. Then target drawing and noting of target position, tumor volume, lung function, patient gender, age and weight were performed. The images during the course of inspiration and expiration in simulator were scanned and transferred into TPS by DICOM RT port. At last, the three-dimensional displacement curve of the interested points(X,Y and Z axis) could be obtained. Results The three-dimensional real time displacement curve of lung cancer interested points could be estab-fished by the way of collecting simulator images and drawing interested points. The maximum displacement range of the interested points were 4.2mm in Z-axis(head-foot direction), 3.8ram in X-axis(left-right direction), 2.9ram in Y-axis(ante-rior-posterior direction). Conclusion The three--dimensional real time displacement curve of lung cancer at any point of the target can be established by collecting the dynamic images in simulator and reconstructing of the corresponding images in target planning system through the DICOM RT.
