Objective: To investigate the effects of bovine plasma fibronectin on the proliferation and differentiation of rat osteoblasts. Methods:Rat osteoblasts were cultured and identified. AlamarBlue were used to determine the effect of various concentration of bovine plasma fibronectin on the proliferation of the osteoblasts. ELISA method was used to determine the alkaline phosphatase activity of the cells. Results: Fibronectin stimulated the proliferation of rat osteoblasts at 40 ?g/ml (P

Objective To investigate the value of multi-slice spiral CT (MSCT) in diagnosis of colorectal carcinoma. Methods MSCT images of 42 cases of colorectal carcinoma proved by surgery and pathology were retrospectively analyzed. Multiplanar reconstruction (MPR) in all cases, and curved planar reconstruction (CPR), shaded surface display (SSD), CT virtual colonoscopy (CTVC) and Raysum were performed in some of the cases. MSCT findings were analyzed in comparison with operative and pathologic features. Results The detecting rate and quatitative rate of colorectal carcinomas with MSCT were 100%,respectively.The accurate rates were 82.9%(29/35) and 100%(7/7) in detection of invasion of surrounding structures and metastasis in abdominal organs respectively,the sensitivity and specificity for detetion of lymph node metastasis were 71%(22/31) and 100% with MSCT imaging.Conclusion MSCT scan with multiform reconstruction techniques can make definite diagnosis of colorectal carcinoma, which is helpful for treatment plan.

Objective:To detect the expression of cyclin B 1 in human ameloblastoma(AB). Methods:Expression of cyclin B1 was detected in 73 cases of AB (32 primary, 33 recurrent and 8 malignant cases), 19 of odontogenic keratocyst (OKC) and 7 of normal oral mucosa by streptovidin-biotin method. Results:The ratio of positive nuclear expression of cyclin B 1 in normal oral mucosa, OKC and AB was 28.6%(2/7), 36.8%(7/19) and 63.0%(46/73) respectively (P

The disc degeneration disease has been main research focus in spinal surgery,but the pathogenesis of disc degeneration is still not clear.Appropriate animal models are important for the study of pathogenesis of disc degeneration.Presently,models of disc degenetation are mainly classified into two categaries:vitro models and vivo models.The animal vitro models include disc cell models and disc tissue models.The vivo models include mechanics models and trauma models.This review tries to give a short introduction about the status and progress of animal model about disc degeneration.

Objective To open out new method,we probe into immune function of??ST and NKT cells in NSCLC.Methods The peripheral blood cells were stained with antibodies labeled with fluorescence in NSCLC,??T,NKT and their set group cells were counted with flow cytometry.Results The absolute counts of??T,CD~+_(56)??T,CD~-_(56)??T,NKT and??T~+ NKT cells in NSCLC was significantly lower than that of normal controls.The relative counts of NKT,??T~+ NKT,??T~-NKT and CD~+_56??T cells in NSCLC was not sig- nificantly lower than that of normal control.The absolute counts of??T cells in NSCLC positively correlated to the number of NKT cells,(r=0.426,P=0.009).Conclusion The absolute counts of??T,NKT and their set ground cells in NSCLC was significantly lower than that of normal controls.In NSCLC the relation of the??T and NKT had positive correlation.

The effect of PubMed on the development of biomedical journals and the role of its Linkout function in extending the effect of journals were analyzed , followed by a description of the technologies and methods for the full-text seamless link of journal Websites and PubMed using its Linkout function with Biomedical and Environmental Sciences as an example .

The JC virus is a widely infected human polyomavirus. Recent foreign researches showed that the JC virus infection is correlated with tumors of nervous system and digestive system, while, and study on the relationship between JC virus infection and gynecological tumor is seldom reported. In this study, we first establish the nucleic acid detection methods and procedures for JC virus and its highly homologous BK virus. The JC and BK viruses infection was evaluated by detect the viral DNA in samples including biopsy tissues, serum as well as urine of myoma of uterus (98 cases), cervical cancer (84 cases), endometrial cancer (40 cases) and ovarian tumor (72 cases) patients. The BK viral DNA positive rate was significantly higher in urine samples than that of blood and biopsy samples, and there is no significant difference of the BK viral DNA positive rate among all patient groups. The JC viral DNA positive rate is almost 0 in serum samples and biopsy. tissues, however, viral DNA positive rate is more than 50% in urine samples. In fibroids group, the JC viral DNA positive rate is up to 65. 3% which is significantly higher than that in other patients groups and healthy control. Further gynecological tumor associated viruses detection showed that only human papilloma virus infection is associated with cervical cancer, the herpes simplex virus, EB virus and cytomegalovirus infection is extremely low in our patient groups. No synergistic effect on gynecological tumor caused by viruses co-infection was observed. Our study showed that JC virus infection is highly related to the pathogenesis of uterine fibroids.

Objective To investigate the efficacy of preoperative transcatheter artery chemoembolization (TACE) correlates with outcome after orthotopic liver transplantation (OLT) in patients with hepatocellular carcinoma (HCC). Methods Sixty-seven patients with HCC underwent TACE before OLT. In all the patients, there were 52 males and 15 females with age ranging from 34 to 67 years old (average 48). Sixty-one patients met the Milan' standard, and 6 patients exceeded Milan' standard. Classic OLT was done in 62 patients and pigyback liver transplantation was done in 5 patients. Immunosuppression regimen after operation included Tacrolimus (or Ciclosporin,Sirolimus), mycophynolate, steroid hormone. The efficacy of TACE was assessed according to histological findings after OLT. Tumor recurrence rate of 1-and 2-year tumor recurrence rate, and 1-and 2-year survival rate in different groups with different responses to preoperative TACE were compared. Results Tumor necrosis rate was greater than 50% in 50 patients and new tumor nodi occurred in 2 patients. Tumor necrosis rate after TACE was 73. 77%. Tumor necrosis rate was less than 50% in 17 patients and new tumor nodi occurred in 7 patients. Forty-eight patients had satisfactory efficacy after TACE and no new tumor nodi occurred, 1-and 2-year tumor recurrence rate was 2. 08/ (1/48) and 6. 25% (3/48) respectively, and 1- and 2-year survival rate was 97. 92% (47/48) and 95. 83% (46/48) respectively. Nineteen patients had worse efficacy after TACE and new nodi occurred, 1- and 2-year tumor recurrence rate was 36. 84% (7/19) and 57. 89% (11/19), and 1-and 2-year survival rate was 73.68% (14/19) and 47. 37% (9/19) respectively. There were statistically significant difference between the two groups (P＜0.05). Conclusion TACE provides good local control in preoperatively diagnosed HCC, but its impact is limited in lesions not detected preoperatively. Patients with satisfactory efficacy after TACE before OLT had a good prognosis. The response to preoperative TACE may predict long-term outcome after LT.
