Objective To establish a mouse model of lymph node metastasis of breast cancer cells by luciferase imaging assay,to monitor early process of lymph node metastasis,and to evaluate the effect of X-ray radiation therapy on tumor.Methods The mouse mammary cancer cell line 4T1-Luc expressing luciferase was inoculated subcutaneously into the paw pad of nude mice to establish a model of subcutaneous lymph node metastasis.The lymph node metastasis in nude mice was continuously observed by in vivo fluorescence imaging system,and the nude mice with early lymph node metastasis of breast cancer cells were divided into control group and treatment group randomly.The radiotherapy effect was observed by in vivo fluorescence imaging system and evaluated by the pathological changes of HE staining of tumor tissue.Results A mouse lymph node metastasis model of breast cancer cells was successfully established,and the volume of primary tumor in paw correlated with the fluorescence photon number positively (r =0.958,P ＜ 0.001).On the twenty-fourth day after inoculation,the fluorescence photon number in pad tumor and popliteal fossa tumor of treatment group were significantly decreased in comparison with the control group (t =32.58,P ＜ 0.05),and the inhibition ratio of radiotherapy on tumor growth approached to 85 ％.HE staining showed that the apoptosis and necrosis in irradiated tumor was obviously higher than that in control group.Conclusions Bioluminescence imaging technique can be used to evaluate the effect of X-ray on breast cancer suppression and lymph node metastasis in mice.

OBJECTIVE:To compare the effects of prophylactic application of 3 different antibiotics on prognosis in patients underwent breast lesion resection. METHODS:1 066 patients with breast lasion resection from 12 hospitals of Shaanxi province were divided into trial group(360 cases),control group A(352 cases)and control group B(354 cases)according to random num-ber table. Trial group was given first generation cephalosporin cefazolin;control group A was given second generation cephalospo-rin cefuroxime;control group B was given third generation cephalosporin cefoperazone sodium and tazobactam sodium. The dosage regimens of 3 groups were as follows:relevant drug 2 g added into 0.9%Sodium chloride injection 100 ml,ivgtt,0.5 h before sur-gery,medication course≤24 h after surgery in trial group. Those indexes of 3 groups were observed,such as post-operative ADR, incision healing,infection,hospitalization duration,phamaceutical costs per capita. RESULTS:There was no statistical signifi-cance in the rate of incision healing and the rate of post-operative infection among 3 groups(P>0.05). The incidence of post-opera-tive ADR,hospitalization duration and phamaceutical costs per capita in observation group were significantly lower or shorter than in control group A and B,with statistical significance(P<0.05). CONCLUSIONS:Cefazolin is better than cefuroxime and cefo-perazone sodium and tazobactam sodium to reduce the postoperative adverse reaction,antibiotics cost per capita and hospital drug cost per capita,shorten the hospitalization duration.

ObjectiveTo establish an animal model of implanted inferior vena cava tumor thrombus (IVCTT)and examine its growth with MDCT and 3D-MPR. MethodsTumor cell line VX2 was inoculated subcutaneously into rabbit to develop the primary tumor, which was then cut into small strips. Purse-string suture was performed on the anterior wall of IVC after the laparotomy in eighteen New Zealand white rabbits.The tumor strip was injected into IVC through the purse and suspensory fixed on the inner wall of IVC. The general conditions,body weight,and the survival time were monitored after operations.MDCT examinations were performed with plain scan,arterial phase,portal phase and venous phase enhancement every week for all animals and 3D-MPR were acquired.The volumes of IVCTT were calculated.IVC,IVCTT and metastasis were examined with gross and histological pathology. ResultsThe IVCTT was confirmed by MDCT and 3D-MPR images.Collateral varicose veins caused by IVC obstruction and metastasis were also shown in images.IVCTT and metastasis were confirmed by pathological method. The success rate of IVCTT was 100 ％. The mean survival time of operated animals was(49.5±4.4)days. ConclusionsInjecting and suspensory fixing VX2 tumor strip into IVC is a reliable method to establish the IVCTT animal model. MDCT and 3D-MPR are valuable methods to monitor the growth and metastasis of IVCTT in animal models. The model of implanted IVCTT of rabbits provides a useful tool for the research of treatment of IVCTT.

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.
