There is a long history of Toad venom in the treatment of cancer in China.Bufalin,extracted from Toad venom,is one of the biologically active compounds of anticancer.We elaborate the molecular mechanism of bufalin on anticancer activity from several aspects such as inducing cell apoptosis and differentiation,inhibitting cell proliferation and angiogenesis,enhancing the sensitivity of chemotherapeutics,which can provide the basis for in-depth study of Toad venom and its development and clinical medication.

Purpose:To evaluate the efficacy and toxicity of combination of MabThera and CEOP regimen in the treatment of aggressive B-cell lymphoma. Methods:21 patients diagnosed as aggressive B-cell lymphoma with median age of 48 years old (from 15 to 68 years old),received the treatment of MabThera plus CEOP regimen. This treatment consisted of MabThera 375 mg/m2 intravenously infusion on day 1,cyclophosphamide 750 mg/m 2 ,epirubicin 60 mg/m 2 ,vincristine 2 mg on day3 ,prednisone 40 mg/m 2 orally taken on day 3~7. Results:In all 21 patients,16 (76.2%) complete response and 3 (14.2%) partial response were observed. Thus,the overall response rate was 90.5%. Moreover,of the remaining patients,1(4.8%) achieved stable disease and 1(4.8%) had progressive disease. In the 19 responsive patients,the follow-up duration were from 2 to 15 months. One case of thyroid lymphoma experienced recurrence after 14 months with complete response. Until now,the other responses have been maintained. Only one dose of MabThera infusion related-toxicity was observed in all who received 87 cycles. The hematological toxicities were mainly leucopenia and neutropenia. 5( 23.8% ) experienced 3-4 grade neutropenia. Only 1 patient developed neutropenia fever. The other non-hematological toxicities were 1-2 grade except grade 3 alopecia. Conclusions:The combination of MabThera and CEOP regimen had high efficacy with mild toxicity in the treatment of aggressive B-cell lymphoma,hopefully may become the standard treatment.
4.Development of a nano-TiO_2 ceramic-coated orthodontic bracket
Journal of Practical Stomatology 1996;0(02):-
Objective:To develop nano-TiO_2 ceramic-coated orthodontic brackets, and to study the surface characters of ceramic film. Methods:TiO_2 nanoparticles were synthesized by the Gel-Sol method. Electron beam physical vapor deposition(e-beam PVD)technology was used to deposit the nano-TiO_2 ceramic film on the surface of the orthodontic brackets, which were manufactured by the Xinya factory, Hangzhou.The surface properties of the nano-TiO_2 ceramic film were observed with scanning electron microscopy(SEM),transmission electron microscopy(TEM) and X ray power diffraction(XRD).Results:The synthesized TiO_2 particles were uniform with the diameter of (6?2) nm. The TiO_2 ceramic film on the orthodontic brackets was 5~8 ?m in thickness, with smooth surface and anatase stratiform structure.Conclusions:The nano- TiO_2 ceramic film has good surface properties and actinochemistry characters without any influence on the slot size.

Objective To observe the relationship between serum bilirubin levels of elderly heart failure patients and type, clinical symptom and prognosis of the heart failure. To explore the pathophysiological role of heme oxygenase 1/CO bilirubin system in the pathogenesis of the heart failure. Methods Serum total bilirubin and direct bilirubin and indrect bilirubin levels of 57 inpatients admitted to our depatment because of heart failure from April 1998 to June 2000 were examined in the second day, first and second week after admission, respectively. Results (1) Compared with the recovery stage of the heart failure, the serum total bilirubin levels during the heart failure attack increased by 52 9% and 78 9%, respectively than the first and second week after the attack(26 1 ?mol/L vs 17 4 ?mol/L and 14 6 ?mol/L, P

Objective To evaluate the surgical treatment of huge staghorn stones. Method The clinic dates of 184 cases treated with an incision of the infrarenal sinus supplemented by a postrenal low pole segmental incision were studied. Result 184 cases were all successful.Conclusion We conclude that this method, need no interruption of renal blood flow had advantages of simple procedure less bleeding, completely removing calculi, protecting renal function.

Objective:To observe the effect of soluble CD14 (sCD14) on the inducing activity of lipopolysaccharide(LPS) on human gingival fibroblasts(HGFs). Methods:In vitro cultured HGFs were stimulated by FITC labeled LPS at the concentration of 0 (control), 100 ng/ml, 100 ng/ml LPS+100 ?g/ml sCD14 and 100 ng/ml LPS+100 ?g/ml ENP respectively for 24 h. The binding activity of LPS to HGFs was measured in the level of mean fluorescence intensity of FITC-LPS.TNF-? and IL-6 in the culture supernatant were measured by ELISA. Results:The binding activity of FITC-LPS to HGFs and the level of TNF-? and IL-6 in culture supernatant were significantly decreased in sCD14 and ENP group(P
