Objective: To study the mechanism of effect of total flavone of rhizoma drynariae in groups with different dosage on osteoblasts cultured in vitro. Methods: To culture osteoblasts with UMA-106-01 osteoblast strain and to observe the activity of ALP and the endosmosis of 3H-TdR. Results: The total flavone of rhizoma drynariae increased the activity of ALP in cells cultured with UMR-106-01 strain. The ALP activities correspondingly changed in the 24h, 48h and 72h, which related to dosage effect and time effect. Among them, the activity in the 48h is the most ideal one. And the amount of endosmosis of the total flavone of rhizoma drynariae to 3H-TdR increased more remarkably in the 48h than that in the 24h and it also related to the time effect. Conclusion: The total flavone of rhizoma drynariae can promote the differentiation and multiplication of osteoblasts.

Objective To investigate the incidence of infection and the effect of anti-infection prophylaxis in renal transplanted patients after Basiliximab induction therapy. Methods A total of 204patients who have received renal transplantation and Basiliximab induction therapy from January 1,2001 to December 31, 2010 in our hospital have been retrospective analysed in this study. These patients were divided into a prophylaxis group (118 cases) with Ganciclovir + Sulfadiazine +Trimethoprim therapy and a control group (86 cases) without any anti-infection prophylaxis.Furthermore, 440 transplanted patients in the same peroid without any induction therapy were also analysed. They were also devided into two groups: an anti-infection prophylaxis group (206 cases)and a control group (234 cases) without any anti-infection prophylaxis. Results In the prophylaxis group with Basiliximab induction therapy, there were 23 patients (19. 5 %, 23/118)experienced hospitalization due to infection, 3 cases (13. 0 %,3/23) among them were severe infection, and 3patients (13.0 %, 3/23) died from vital infection. In the non-prophylaxis control group with Basiliximab induction therapy, 27 patients (31.4 %, 27/86) had infection complication, 7 patients (25.9 % ,7/27) among them were severe infection, and 4 patients(14. 8 % ,4/27)died. The incidence of infection between the above two groups is significantly different (P＜0. 05). In the prophylaxis group without induction therapy, the incidence of infection was 15.0 % (31/206), there were no severe infection cases but 7 patients (22. 6 %, 7/31) died from infection. In the non-prophylaxis control group without induction therapy, the incidence of infection was 12. 8 % (30/234), 3 cases among them were severe infection(10. 0 %,3/30)and 5 patients died from infection (16. 7 %, 5/30).The incidence of infection in Basiliximab induced patients without anti-infection prophylaxis is significantly higher than that in patients without induction therapy and anti-infection prophylaxis (31.4 % vs. 12.8 %,P＜0.01). Conclusion Basiliximab induction therapy increased the risk of infection, but not the rate of mortality. It is necessary to give anti-infection prophylaxis in renal transplanted patients with Basiliximab induction therapy.

Objective To investigate the infection following the lymphocytes deleted agent (ATG) and IL-2 receptor antagonists (Basilixinab and Daclizumab)-based induction therapy after renal trausplantation.Methods A retrospective analysis was carried out on 701 kidney transplant recipients between Jan. 1,2005 to Dec.31,2010.According to exclusive and inclusive criteria,finally 549 patients were evaluated,including 429 patients treated with ATG (ATG group) and 120 patients with anti-CD25 monoclonal antibodies (monoclonal antibodies group; 86 patients with Basiliximab,and 34 patients with Daclizumab).The incidence of acute rejection,infection rate,infection time,hospital stay,severe infection rate and mortality were analyzed.After operation,the patients received an immunosuppression therapy including Tacrolimus (cyclosporine A),Mycophenolate-Mofetil and prednisone to present rejection. Part of the patients were treated with ganciclovir and sulfamethoxazole sulfadiazine and trimethoprim for infection prevention.Results The acute rejection rate in ATG group and monoclonal antibodies group was 15.9％ (68/429) and 10.0％ (12/120),and there was no statistically significant difference (P＞0.05).The infection rate in ATG group was 11.9％ (51/429),including 13.7％ (7/51) with severe infection,and mortality was 7.8％(4/51).The infection rate was 15.0％ (18/120) in monoclonal antibodies group,including 11.1％ (2/18) with severe infection,and mortality was 5.6％ (1/18).There was no statistically significnat difference in infection rate,severe infection rate and mortality between two groups (P＞0.05).The hospital stay in ATG group and monoclonal antibodies group was 25.8 days and 19.1 days respectively (P＜0.05).Dead cases had not received regular anti-infection treatment,and the patients age was over 50 years.Conclusion The infection risk and mortality between these two induction therapies are identical,but hn comparison to the patients using ATG,the infection of patients using anti-CD25 monoclonal antibodies is easier to control.Anti-infection prophylaxis is important to reduce infection rate and decrease infectious mortality.

Objective To explore disinfection efficacy of anerdian using swab and spray disinfection methods.Methods Hands of 30 subjects were randomly divided into the swab group and the spray group.The samples of before and after disinfection in each group were collected separately and observed their disinfection effect.Results The number of bacteria showed no significant difference between the two groups.The passing rate of disinfection reached 100％.The time of disinfection in the spray group was (2.58±0.32)s,significantly less than that in the swab group,(12.26±1.48)s,however,the drying time in the spray group was (42.37±1.79)s,significant longer than that in the swab group,(26.24±1.46)s.A subject hand disinfection used 0.5ml 0.2％ anerdian in the spray group,and 0.75ml 0.2％ anerdian and two cotton buds was used in the swab group.Conclusions There is identical disinfection efficacy between spray and swab methods.Spray disinfection method has short operating time,less use of disinfectant without using cotton buds,it is able to replace swab disinfection and will play an important role to reduce medical waste and health care costs.

Objective To investigate the influence of proline-rich tyrosine kinase 2 (Pyk2)gene RNA interference on proliferation,invasion and migration of Hep3B hepatocellular carcinoma cells.Methods The Pyk2 gene RNA interference vector was transfected in Hep3B hepatocellular carcinoma cells by lipofectamine. The Hep3B cells divided into three groups:siRNA group (the vector with Pyk2 RNAi gene was transfected), negative control group (the vector without Pyk2 RNAi gene was transfected),and blank control group (no vectors was transfected).Pyk2 mRNA and protein were detected using reverse transcription reverse transcription-poly-merase chain reaction (RT-PCR)and Western blotting.The biological behavior including cell proliferation,inva-sion and migration were detected by 3-(4,5-dimethyl-2-thiazoly)-2,5-diphenyl-2H-tetrazolium bromide (MTT), transwell and wound healing assay,respectively.Results The expression of Pyk2 mRNA of Hep3B cell line in siRNA group (0.1 6 ±0.03)was significantly decreased than those in negative group (0.74 ±0.1 3)and blank control group (0.77 ±0.1 6),with statistically significant differences (t=51 .46,P=0.000;t=53.21 ,P=0.000).The expression of Pyk2 protein of Hep3B cell line in siRNA group (0.24 ±0.06)was significantly decreased than those in negative group (0.83 ±0.05)and blank control group (0.91 ±0.06),with statisti-cally significant differences (t=57.29,P=0.000;t=68.53,P=0.000).The cell proliferation inhibition rate at 48 hours in siRNA group (26.1 7%±0.28%)was significantly raised than those in negative group (9.28%± 0.22%)and blank control group (6.47%±0.31%),with statistically significant differences (t=31 .45,P=0.004;t=34.64,P=0.002).The number of transmembrane cells in siRNA group (32.5 ±8.5)/1 0 HP was significantly declined than those in negative group (98.4 ±1 2.3 )/1 0 HP and blank control group (1 1 2.6 ± 1 1 .3)/1 0 HP,with statistically significant differences (t=95.64,P=0.000;t=1 05.1 7,P=0.000).The wound healing assay in siRNA group (28.1 7%±1 .46%)was significantly lower than those in negative group (77.38%±2.24%)and blank control group (79.41%±3.1 7%),with statistically significant (t=85.86,P=0.000;t=89.37,P=0.000).Conclusion Pyk2 gene involves the proliferation,invasion and migration of Hep3B cells,which has close correction with development and metastasis of hepatocellular carcinoma.Pyk2 gene is very helpful to become a molecular target for the diagnosis and treatment of hepatocellular carcinoma.
