Tenascin-C (TNC) is an extracellular matrix glycoprotein, which is usually highly expressed in embryonic tissues and tumor tissues, but is not expressed or just lowly expressed in mature tissues. TNC is involved in various complex signaling pathways during tumor metastasis, especially through modulating FAK, RhoA, Wnt and Notch pathways by interacting with syndecan-4, integrin α5β1, matrix metalloproteinases (MMPs) and vascular endothelial growth factor (VEGF). As a result, TNC affects epithelial mesenchymal transition, tumor cell adhesion, proliferation and angiogenesis, which eventually enhances the invasion and metastasis ability of many tumors. Further studies have demonstrated that TNC could be used as prognosis or metastasis marker of patients with malignant tumor.

Objective To explore the timing of wound closure and the choice of methods in Gustilo Ⅲtype tibiofibula open fractures after emergency debridement.Methods 42 patients with Gustilo Ⅲ type tibiofibula open fractures from January 2014 to January 2015 were selected as the observation group.All patients were performed emergency fracture fixation after debridement and wound secretion culture immediately after debridement, if the training result was positive,the debridement,again until the training results for negative when square in 48 hours after closing a wound.Selected 38 patients with GustiloⅢtype tibiofibula open fractures,the prompt debridement 38 cases were fracture fixed routine treatment after closing the wound,they were set as the control group.Compared two groups of patients with wound infection and fracture healing.Results The fractures wound infection rate of the observation group was 4.76%,which was significantly lower than 15.79% of the control group,the difference was statistically significant(χ2 =10.739,P=0.000).The wound healing time and fracture healing time of the observation group were significantly better than those of the control group,there were statistically significant differences( t=9.684,7.324,all P<0.05).Conclusion GustiloⅢtype emergency open tibiofibula fracture after debridement of the wound closure time should according to the results of wound secretion culture,cultivate the results can be achieved when the negative for wound closure,according to the degree of injury of soft tissue,to choose the right means of wound closure.

Objective: To develop a way of high-quality real-time three dimension surface reconstruction for high-resolution volume data.Method 3D surface point sets of single organ were using a method of binding the threshold and morphological operations.The normal vector of every surface point was calculated.According to the gray gradients of volume data,the triangle face was replaced by surface points to describe the organ surface,and the surface was displayed with OpenGL interface of display card after defining the color and transparent of the organ surface.Result Based on hardware platform of personal computer,the reconstruction of skeleton and skin for the digitized virtual Chinese man No.1(VCH-M1) from CT database was constructed,the rendering speed was faster than 25 F/s.Conclusion The algorithm is capable of realizing a real-time rendering for 512?512?1720 high resolution volume data.

OBJECTIVETo evaluate the possibility of vaginal hysterectomy for patients with moderately enlarged uterus of benign lesions.

METHODSOne hundred and seventeen women with benign uterine diseases underwent vaginal hysterectomy. These patients were divided into two groups according to uterine weight. Group I contained 60 patients with uterine enlargement to a weight of 200 to 750 g, and group II contained 57 patients with uterine weight of less than 200 g. Uterine morcellation was performed in some cases. The perioperative data in both groups were analyzed.

RESULTSIn group I, 59 cases underwent transvaginal hysterectomy successfully, except 1 case converted to abdominal operation and the uterine morcellation was performed in 21 women. In group II, all patients successfully underwent transvaginal hysterectomy without any assistance of special technique. The mean uterine weight of group I was significantly heavier than that of group II (280.18 +/- 100.40 g vs 146.48 +/- 35.19 g). The mean operating time was significantly longer for group I than that for group II (83.93 +/- 26.26 minutes vs 35.22 +/- 20.55 minutes). There were no significant differences in blood loss and complications between group I and group II. There was no injury of urinary bladder or rectum, and no vaginal vault infection.

CONCLUSIONSVaginal hysterectomy of moderately enlarged uterus can be safely and effectively performed by experienced operators. In some cases, in order to reduce the uterine volume, uterine morcellation should be used to shorten operative time, reduce the bleeding, and lower the postoperative complications.

Preparation of maternal strain A/PR/8/34 HA antiserum for influenza virus classical reassortment. A/PR/8/34 virus was digested by bromelain after inactivation and purification. 5%-20% sucrose continuous density gradient centrifugation method was used to purify HA protein. SIRD method was used to select the target protein. SDS-PAGE method was used to identified HA protein. High Immunogenic A/PR/8/34 HA protein was successfully prepared and HI titer reached 10240. High purity HA antiserum was identified by SIRD method. The key reagent in the classical reassortment of influenza virus was prepared, and the complete set of technical methods were explored, which laid the foundation for the independent research and development of seasonal influenza vaccine strains of China.

Objective:To study the compatibility and stability of coenzyme A for injection, adenosine disodium triphosphate and inosine injection. Methods:By simulating the clinical medication, the three drugs and 5% glucose injection were mixed together. The contents and relative substances of coenzyme A, adenosine disodium triphosphate and inosine were measured by HPLC. The changes in appearance, pH and insoluble particles were observed or tested at ambient temperature. Results:The mixed solution showed no signifi-cant changes in appearance, pH, number of insoluble particles, contents and relative substances of coenzyme A, adenosine disodium triphosphate and inosine in 4 h, while the mixed solution became turbid and the pH, number of insoluble particles and contents of the three drugs showed significant changes after 24-h storage. Conclusion:The mixed solution of coenzyme A for injection, adenosine dis-odium triphosphate and inosine injection in 5% glucose injection should be used up in 4 h at ambient temperature.

AIM: To investigate the effect of canstatin on cultured rabbit vascular smooth muscle cells(VSMC). METHODS: By means of cationic liposome mediated method, canstatin RNA was transferred into cultured VSMC. The proliferation quantity of VSMC were determined by the cell counting method and thymidine(-TdR) incorporation. RESULTS: Canstatin RNA could be effectively transferred into cultured primary rabbit aortic smooth muscle cells by the cationic liposome-Dosper and could markedly inhibit VSMC proliferation. CONCLUSION: Transfection of canstatin RNA could inhibit the growth of VSMC in vitro.

Objective To study binocular rivalry (BR)objectively and the correlation between fusiform face area (FFA)and visual cortex.Methods Six subjects participated in this study,with one eye presented a normal face expres-sion picture flickered at 8.57 Hz,while the other presented a fearful face flickered at 12 Hz or 15 Hz,respectively.Electro-encephalogram(EEG)was recorded during this process.Steady state visual evoked potential(SSVEP)evoked by two flick-ering rates was analyzed by time-frequency analysis of short time fourier transformation(STFT).The time index of BR was estimated and the correlation coefficient between FFA and visual cortex compared.Results The total average time was (411.6 ±73.8)ms for the left eye and (547.6 ±126.7)ms for the right eye.The switch rate of the two groups was not different,but the left FFA was more sensitive than the right FFA in process of the fearful face.Neither side of FFA had any frequency preference to the flickered fearful face.Conclusion SSVEP can be used as a frequency tag of BR or as a tool to evaluate visual sensation under BR objectively.SSVEP combined with BR can be used in research of neural mechanisms of visual awareness.
