Background:In recent years,the incidence and mortality of colorectal carcinoma have been increasing rapidly. Diagnosing and treating cancer at gene level have become a new effective approach. Aims:To investigate the expression of S-phase kinase-associated protein 2(Skp2)and its relationship with vascular endothelial growth factor(VEGF)and tumor microvessel density(MVD)in colorectal carcinoma. Methods:Thirty-five colorectal carcinoma patients from March 2014 to March 2015 at People’s Hospital of Hubei University of Medicine were enrolled. Fifteen para-cancerous tissue samples were served as controls. The expressions of Skp2,VEGF and MVD value were determined by immunohistochemical SP, and their relationships with clinicopathological characteristics were analyzed. Results:The expression of Skp2 in colorectal carcinoma was significantly higher than that in para-cancerous tissue( P = 0. 000),and was correlated with tumor differentiation and lymph node metastasis(P < 0. 05),but not with gender,age and TNM stage(P > 0. 05). Expression of VEGF and MVD value were significantly higher than those in para-cancerous tissue(P = 0. 019,P = 0. 002),and were correlated with lymph node metastasis and TNM stage(P < 0. 05). Expression of Skp2 was positively correlated with the expression of VEGF and MVD value in colorectal carcinoma( r = 0. 569,P = 0. 000;r = 0. 481,P = 0. 017 ). Conclusions:The abnormal high expression of Skp2 is involved in the angiogenesis of colorectal carcinoma. Skp2,VEGF expressions and MVD value may be served as important markers for malignancy degree of colorectal carcinoma.

ObjectiveTo observe the synergistic action of lower He-sea and Front-mu points in treating functional dyspepsia by adopting electroacupuncture at the lower He-sea and Frong-mu points of stomach.MethodSixty patients with functional dyspepsia were randomized into a lower He-sea group, a Front-mu group, and a combining group of lower He-sea and Front-mu points, to receive treatment once daily, 5 sessions a week, totally for 4 weeks. Nepean Dyspepsia Index (NDI) was tested before and after intervention, and the general therapeutic efficacy was evaluated.ResultThe total effective rate was 100.0% in the combining group, versus 90.0% in the Front-mu group and 90.0% in the lower He-sea group, and the differences were statistically significant (P<0.05). The follow-up study showed that the total effective rate was 100.0% in the combining group, versus 90.0% in the Front-mu group and 85.0% in the lower He-sea group, and the differences were statistically significant (P<0.05). Before treatment, therewere no significant inter-group differences in comparing Nepean Dyspepsia Symptom Index (NDSI) and Nepean Dyspepsia Life Quality Index (NDLQI)(P>0.05), while there were significant differences in comparing NDSI and NDLQI after treatment (P<0.05). ConclusionIt can improve the functional dyspepsia symptoms by using the lower He-sea point and Front-mu point together or using them separately, while the combining use can produce a more significant efficacy.

PurposeTo analyze the sonographic and the histological features of special types of breast malignant tumors in order to explore preoperative ultrasound diagnosis. Materials and Methods Seven cases of special types of breast malignant tumors confirmed by pathology were retrospectively investigated by ultrasound. The sonographic and histological features of the lesions were reviewed. The ultrasonogram manifestations of the breast anatomy and the lesions were observed and recorded.Results Among 7 cases, there were 2 cases of papillary carcinoma, 3 cases of mucinous carcinoma, and 2 cases of lymphoma. Microscopically, the papillary carcinoma had clear boundaries with infringing mesenchyme, and the tissues were papillary and dense. The mucinous carcinoma had cancer cells floated in mucus lake. The primary breast lymphoma was diffused large B-cell type with focal lesion. For sonography type of breast, there were 3 cases of fatty types, 1 case of fibroglandular-1 and 3 cases of fibroglandular-2. The papillary carcinoma was hypoechoic in 2 cases, one of them was expansive growth with large size. Two cases of mucinous carcinoma were hypoechoic without accompanying sound attenuation in 1 case and with accompanying acoustic shadow due to calcification in the other case. Lymphoma was apparent anechoic and cystoid.Conclusion Special types of breast malignancies have different sonographic features and histological features from the common invasive ductal carcinoma. It has high clinical significance to enhance the understanding of rare malignant breast tumors.

BACKGROUND:With the improvement of cervical posterior surgical techniques, lateral mass screw fixation technology has been widely used in the reconstruction surgery of the cervical spine for stability. However, currently, the finite element study on the lateral mass screw fixation reconstruction of the cervical spine is rare. OBJECTIVE:To establish a fine normal lower cervical spine (C3-C7 ) three-dimensional finite element model and a reconstructed finite element model with three-segment laminectomy with lateral mass screw fixation. Then, to do an initial biomechanical analysis of the lateral mass screw fixation reconstructed lower cervical finite element model. METHODS:We col ected a normal female volunteer aged 30 years old to do CT scan for the whole cervical spine. The Dicom data were obtained. Then, the CT scanning images were dealt with software Mimics 10.01, Geomagic Studio 12.0, Solidworks2012, HyperMesh 10.1 and Abaqus 6.12 software to build the normal lower cervical spine (C 3-C7 ) finite element model, the laminectomy finite element model and the rebuilt finite element model. At last, we analyzed the stress changes of reconstructed models under the state of flexion, extension, lateral bending and rotational motion. RESULTS AND CONCLUSION:The lower cervical spine finite element model contained 503 911 elements and 93 390 nodes with a fine realistic appearance. It successful y passed the validation. The surgical procedure was completed in the software, and the lateral mass screw fixation reconstruction finite element model has been established. Lateral mass screw fixation system provides good stability for the postoperative finite element model. The activity of rebuilt finite element model is much lower than the normal finite element model. In the extension condition, the stress of lateral mass screw fixation system becomes strong.
