Purpose:To evaluate clinical utility of carbon dioxide digital subtraction angiography(CO_2-DSA).Materials anti Methods:CO_2-DSA was performed in 85 patients including hepatic.renal,splenic,and super mesenterie arteriography in 75 cases,abdominal artefiography and extremity arteriography in 3 cases,direct portography in 6 cases, hepatic venography in 1 case.Delivery method met the behavior of the gas combination with optimal imaging technique and postprocessing method were applied in order to obtain image accuracy. The images quality of CO_2-DSA was then compared with that of conventional contrast agent arteriograms.Results:CO_2-DSA provided good visualization of the large vascular trunks and their 1st,2nd.grade branches of the target vessels,which could be beneficial for guiding interventional procedures.It was inferior to the conventional DSA in visualization of small vessels, however,CO_2-DSA was superior to conventional DSA in the detection of arterioportal shunts (APS),tumor blood sinuses(including Cavernous hemangioma),retrograde visualization of portal vein.The side effects were minimal.Conclusion:CO_2-DSA could provide accurate, clinical useful veseular images.CO_2-DSA is believed to be a safe and effective alternative to iodine contrast agent.

0.05) .Macroscopic and microscopic observations of all target organs did not reveal any pathologic changes. Conclusion: Domestic-made CO_2 is a safe vascular contrast agent, but further study is necessary to assess the safety of injecting, CO_2 into the cerebral circulation.

Objective To evaluate diagnosis value of PP65 antigenaemia assay(AA) on cytomegalovirus(CMV) infection in febrile children.Method One hundred and twenty-eight febrile children with febrile duration between one to two weeks,their blood preparations and urine aliquots were screened,indirect IF staining(antigen PP65),ELISA(CMV-IgM) and light microscope(urinary cytomegalic inclusion).Three methods above mentioned were used in all patients.Result The positive rate of PP65 antigenaemia,CMV-IgM and urinary cytomegalic inclusion was 17.2%,8.6%,6.3%,respectively.The positive coincidence rate of PP65 antigen with CMV-IgM and PP65 antigen with urinary cytomegalic inclusion was 50%(11/22),36%(8/22),respectively.Nineteen childrens antigenaemia PP65 became negative with patient′s condition improved.Three children′s PP65 antigenaemia remained positive,when they were clinic cured.Two of them became negative after two weeks and one after three weeks.Conclusion Antigenaemia PP65 is effective in early diagnosis of active CMV infection,predicting patient′s condition and providing early intervention and treatment.

Cell-penetrating peptide (CPP) is a kind of small molecular peptide which can pass through a variety of cell membranes. It can carry bioactive macromolecules into cells. Due to lacking of tissue-selecting and targeting behavior, the application of CPP in the field of tumor treatment is limited. Activatable cell- penetrating peptide (ACPP) has brought the dawn to the application of CPP. This review mainly introduces the applications of ACPP in the targeting antitumor drug delivery which was designed based on the differences between tumor microenvironment and normal tissues as well as the exogenous physical stimulation.

OBJECTIVE:To optimize the processing technology of honey-fried Polygonum perfoliatum. METHODS:The pro-cessing method of honey-fried P. perfoliatum was optimized by L9(34)orthogonal test with the contents of effective component quer-cetin and water-soluble extract as comprehensive evaluation index,with the amount of honey,moistening time,baking temperature and baking time as investigating factors. RESULTS:The optimal processing technology was as follows as 30% honey,moistening for 120 min,baking for 50 min at 70 ℃. In verification test,the content of quercetin in 3 batches of honey-fried P. perfoliatum was higher than 0.05%,and the content of water-soluble extract was higher than 25%(RSD<2.5%,n=3). CONCLUSIONS:The optimized processing technology is stable and practical,and can provide reference for standardizing the processing technology and quality control of honey-fried P. perfoliatum.

Objective To analyze the clinical therapeutic effect of lumbar fusion in the treatment of lumbar degenerative diseases in the spine pelvic sagittal balance. Methods From June 2009 to June 2012,the clinical data of 92 cases with lumbar degenerative diseases ac-cepted lumbar spinal fusion operation in our hospital was collected. The contrast lumbar lordosis ( LL) ,lumbar sagittal vertical axis ( SVA) , pelvic incidence angle ( PI) ,sacral inclination angle ( SS) ,pelvic tilt angle ( PT) and other numerical parameters,using the Oswestry disabil-ity index ( ODI) ,visual analogue scale ( VAS) and the Japan Society of Department of orthopedics ( JOA) score were followed up two years after operation,and the postoperative effect was evaluated. Results The spinal pelvic parameters SVA,LL,SS and PT after surgery were changed obviously,and the difference was statistically significant(P<0. 05). The postoperative follow-up of VAS,ODI and JOA score were better than that of preoperation,the difference was significant(P<0. 05). Conclusion Lumbar fusion operation can restore lumbar lordosis, to maintain the spine pelvic sagittal balance and improve the effect of operation,and have positive significance to improve the postoperative symptoms.

Objective:To evaluate the staining of different resin artificial teeth treated by different coloring agents.Methods:1 6 teeth of each brand of Endura Anterio,Heraeus's three color synthetic resin teeth,synthetic resin teeth,Efucera-A,KaiFeng synthetic resin teeth were respectively made into test specimens.A surface roughness tester was used to measure Ra along 3 tracks on each sur-face.The specimens of the same brand were respectively immersed into coffee,tea and vinegar as the test groups and distilled water as a control for 4 weeks.The initial and further color of each specimen was measured using a colorimeter.The CIE L* a* b* values were recorded and color differences (ΔE)after immersion were calculated.Data were statistically analyzed by ANOVA.Results:The color stability of the specimens in coffee and tea was significantly affected by the coloring agents(P <0.05),the higher ΔE was ob-served in coffee than in tea(P <0.05).There were no statistically evident color change in water and in vinegar(P >0.05).The ΔE values in the same coloring agent were as follows:Efucera-A,Heraeus's three color synthetic resin teeth,Endura Anterio,synthetic resin teeth and KaiFeng synthetic resin teeth (P <0.05).Conclusion:Extrinsic pigment can make resin artificial teeth stained,and the staining susceptibility of five resin artificial teeth is different.

Mantle cell lymphoma (MCL), being a kind of aggressive non-Hodgkin ' s lymphoma (NHL), accounts for 6 % - 8 % of NHL in adults which is characterized by malignant B cell infiltration of lymph node, gastrointestinal tract and bone marrow. MCL commonly responds to initial therapy but inevitably occurs relapse and drug resistance. The study on MCL in the 58th American Society of Hematology Annual Meeting has covered many aspects such as basic research, clinical treatment and new drug research. The development of novel mouse model and the exploration of signaling pathways provide a basis for the improvement of MCL pathogenesis and new drug research. VcR-CVAD, VCR and some other chemotherapy regimens designed for different patients have showed satisfactory results. New drugs such as inhibitors of CDK, PI3K and bcl-2 in initial clinical trials are also promising. IACS-010759 and other small molecules provide new directions for the treatment of MCL.
