Objective To research tumor cell apoptosis induced by Lp-THAE of rabbit VX2 liver implanted tumor.Methods 27 New Zealand white rabbits implanted with VX2 tumor at left middle lobe of the liver divided into three groups:Group A(n = 9) Lp-THAE:treated through transhepatic artery catheterization;Group B(n = 9) THAI and Group C(n = 9) as control.The rabbits were executed at second to fifth day after treatment.HE dye microscopy was taken for counting the typical apoptosis cells and calculating apoptosis index(ApI).FITC-AnnexinV/PI assay was used for measuring apoptosis by flow cytometry.Results The ApI of tumor central area and marginal area were(17.769 ? 2.417)%,(4.129 ? 1.172)%,P

Objective To research the angiographic manifestations of rabbit implanted VX_2 liver carcinoma.Methods 34 New Zealand big white rabbit were implanted VX_2 tumor pieces under orthophoria into liver left middle segment.Angiography of coeliac artery-hepatic artery catheterization via right femoral artery was performed at the third week after inoculation.Results The tumor blood vessel and tumor stain in 6 rabbit could be not showed clearly by digital cinematography mode but which could be showed in 28 rabbit by digital subtraction mode.The tumor angiographic signs included:dilating growth of tumor,the feeding arteria surrounding the tumor surface were resemblance to the clenched fist,embraced globosity and wreath in form;many slender vessels from feeding arteria appeared as small bud form,root form and filose form pushed forward to the center from the surface of tumor.The tumor vascular density in periphery was higher than that in center and formed circular or oval tumor stain which more denser at periphery than center.The tumor node stain was complete with definite margin when tumor size was large or equal to 1 cm in diameter,and the tumor stain appeared as clump with indefinit margin.Conclusion There are abundant vascularity for rabbit implanted liver VX_2 tumor,and more abundant at periphery part than center part, coeliac artery catheterization angiography can show the typical manifestations of tumor clearly.

Objective To research the angiographic anatomy of celiac artery in rabbit.Methods 36 New Zealand big white rabbitswere included in this study,the angiography of celiac artery and hepatic artery via right femoral artery was performed,and the branchand diameter of celiac artery system were analysed.Results 66.7% of the celiac arterial opening localized at the level of T_(12) vertebral body low edge,gastrohepatic arterial truncus could been divided into three types : type Ⅰ(47.22%),tree-like branch;type Ⅱ(38.88%),trifurcate branch and type Ⅲ(13.90%),dichotomy branch.The length of proper hepatic artery was from 22.70 to 33.00 mm(26.64 mm?2.28 mm),the inner diameter of proper hepatic artery,left hepatic artery and right hepatic arteria was 0.60~1.20 mm(0.90 mm?0.16 mm),0.60~1.10 mm(0.72 mm?0.09 mm) and 0.50~1.00 mm(0.67 mm?0.09 mm) respectively.The segmental artery of liver could be displaied clearly by proper hepatic artery angiography.Conclusion To realize the angiographic anatomy of rabbit celiac artery would provide a useful help for transhepatic arterial interventional treatment of the liver VX_2 tumor model of rabbit.

To observe the expression of CD40/CD40L on peripheral blood mononuclear cells (PBMC) in patients with condyloma acuminatum (CA), flow cytometry was employed to examine the expression of CD40 and CD40L on PMBC in 36 patients with CA and 20 healthy controls. Our results showed that mean level of CD40 expression in CA patients was significantly lower than that in the controls (6.58% +/- 2.74% vs 14.81% +/- 6.12%, t = 5.703, P < 0.05); the average level of CD40L in CA patients was also significantly lower than that in the controls (0.73% +/- 0.54% vs 2.67% +/- 2.43%, t = 3.532, P < 0.05). Our results suggest that the reduced costimulatory interaction of CD40 and CD40L in CA patients may be one of the important factors responsible for the low cellular immunity.

【Objective】To study the effect of light weight-bearing activity on postmenopausal osteoporosis.【Methods】36 female rats were randomly divided into 3 groups:① Sham,② Ovx (ovarietomized),③ Ovx+Im (ovarietomized and immobilized).All the group's maintained daily activity.And because of being immobilized,the right hind limbs of the third group lacked weight-bearing activity.12 weeks after ovarietomy,the BMD (bone mineral density),histomorphometry and biomechanics of the right femurs of rats were measured and analyzed.【Results】Comparing with the Sham group,the Ovx group's right femurs were manifested with the decrease of BMD,TBV (trabecular bone volume),MTT(mean trabecular thickness) and MCT(mean cortex thickness),while the increase of RS(resorption surface) and OS(osteotoid surface).Meanwhile their biomechanic nature declined.But statistically the BMD,MCT and the criteria of mechanical strength were not significant decrease.Otherwise,the Ovx+Im group's right femurs showed more apparent decrease of BMD,TBV,MTT and MCT.And the biomechanic nature was worse.Comparing with the Sham group,the BMD,MCT and the criteria of mechanical strength of the Ovx+Im group were statistically significant decreased.【Conclusion】If maintaining light weight-bearing activity,the ovarietomized rats were able to maintain relatively better bone quality.A lack of light weight-bearing activity wouldcause thedecline of bone quality.Thusthestudy suggested light weight-bearing activity was significantly effective on the prevention and treatment of postmenopausal osteoporosis.

objective:To investigate the clinical features and prognosis of pinealoblastoma in children. Methods:The clinical data of 10 patients with pinealoblastoma were retrospectively analyzed. These patients were admitted to the Department of Radiation Oncology, Beijing Shijitan Hospital, Capital Medical University from December 2011 to December 2015. Results:This study included 10 patients, with 8 males and 2 females, with a median age of 7 years. Of the 10 patients, 5 underwent gross total resection and 5 underwent sub-total resection. The 10 patients were exposed to craniospinal irradiation after surgery. The median doses of craniospinal irradiation and tumor bed were 30.6 (25.5-36) Gy and 55.8 (50.4-60) Gy, respectively. Of the 10 patients, 4 underwent chemotherapy 1 month af-ter radiotherapy. The median follow-up period was 16.5 (1.5-49) months. The 10 patients survived. No local and distant recurrences were observed. Conclusion:Pinealoblastomas are rare, malignant, and pineal regional lesions that can metastasize along the neuroax-is. Surgery combined with adjuvant radiotherapy and chemotherapy should be applied to patients with pinealoblastoma. Prognosis is also favorable.

Objective To investigate the early diagnostic value of traditional scoring systems in critical acute pancreatitis.Methods From Jan 2007 to Ju12013,consecutive 184 patients with AP who were admitted to the surgical intensive care unit of the Institute of General Surgery,Nanjing Generai Hospital of Najing Militery Region within 72 h from the onset of the disease were studied.Patients were assigned to four groups,including mild,moderate,severe and critical AP according to the determinant based classification and the receiver operating characteristics(ROC) curve was used to predict the presence of critical AP,and Z test and logistic regression was applied to determine the diagnostic value of traditional scoring systems.Results The area under ROC (AUC) of Sofa,BISAP and CTSI score for early diagnosis of critical AP was 0.896,0.877 and 0.862;the best cut off value was 4.5,9.5 and 2.5.Moreover,the AUC of APACHE Ⅱ and Ranson score was 0.807 and 0.707,and the best cut off value was 8.5 and 3.5,respectively.Z test showed early diagnosis rate of Sofa,BISAP,CTSI score was significantly higher than that in Ranson score,and the difference between the two groups was statistically significant (P ＜ 0.05);though they were higher than APACHE Ⅱ score,the difference between the two groups was not statistically significant (P ＞ O.05).Logistic regression showed that high APACHE Ⅱ,Sofa,BISAP and CTSI score were independent risk factors for the development of critical AP (P ＜ 0.05).Conclusions Sofa,CTSI and BISAP score may be clinically important for early diagnosis of critical AP.

Aim To observe the apoptosis of human leukemic cells induced by F951, a novel bcl-2 antisense oligodeoxynucleotide. Methods HL60 cells were cultured with F951 in variant doses. Apoptotic cells were detected by flow cytometry, DNA ladder, electron microscope observation and terminal-deoxynucleotidyl transferase mediated nick end labeling (TUNEL). Results After HL60 cells were treated for 48 hours, mitochondria apoptotic cells can be detected at the ratio of 3.00% in the untreated group, 13.57% in the FNS control group and 30.95%, 38.08%, 52.55% with 5, 10, 20 ?mol?L-1 F951 respectively; the ratio of cells with caspase activity was 0.08% in the untreated group, 0.14% in the FNS control group and 43.68%, 60.54%, 80.37% with 5, 10, 20 ?mol?L-1 F951 respectively. Typical DNA ladder was seen from gel electrophoresis in F951 treated groups, and more apparent effect in the aspect of inducing DNA ladder had been observed with the improvement of F951 concentration. Detected through TUNEL and electron microscope, apoptotic cells in untreated group and FNS control group can only be found by chance, but very commonly seen in F951 treated groups and more frequently with the improvement of F951 concentration. Conclusion F951 can induce cell apoptosis in HL60 cells. Such effect is achieved through the inhibition of bcl-2 gene expression by F951 which initialize apoptosis passageway in consequence.

Aim To study the inhibitory effects of F951,a novel bcl-2 antisense oligodeoxynucleotide,on expression of bcl-2,growth of tumor and survival time of nude mice transplanted subcutaneously with acute myeloid leukemia.Methods HL-60 cells with high expression of bcl-2 were proliferated in vitro.The models of the nude mice with HL-60 cells were established by subcutaneous transplantation with drugs directly injected.The effects of F951 and F951 with low dose Ara-c on growth of tumor and survival time of mice with tumor were observed.The expressions of bcl-2 mRNA in the tumors implanted were detected by fluorescent quantitation RT-PCR.The morphologic structure of tumor tissues was assayed by light microscope.Results After each group mice with tumors were treated for 14 days,the volume,the weight of tumor and the bcl-2 mRNA expression of tumor tissue were shown respectively as follows: NS control group(15.17?3.40)cm3、(12.69?0.92)g、9.79?104 Copies??g-1;FNS group(15.91?3.77)cm3,(12.38?1.21)g;8.31?104 Copies??g-1;Ara-C group(1.24?0.55)cm3,(2.32?0.49)g,2.59?104 Copies??g-1;F951 group(2.6?1.55)cm3,(3.53?0.67)g;1.01?103 Copies??g-1;F951+Ara-C group(0.62?0.48)cm3,(1.05?0.63)g,9.5?102 Copies??g-1.The data above showed that F951 could downregulate the expression of bcl-2 in nude mice with HL-60 cells xenograft and inhibit growth of tumor.The growth of tumor of F951 group was reduced,and the inhibitory rate was 72.18%,there was significant difference comparing control groups with NS and FNS(P
