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.

0bjective To compare the curative effects of GnRH-a and mifepristone in treatment of endometriosis after laparoscopic operation.Methods 114 cases of patients were selected from March 2012 to December 2014 in our hospital with endometriosis after laparoscopic surgery,randomly divided into mifepristone group,GnRH-a group and untreated group,each group for 38 cases.mifepristone group were treated by oral mifepristone one week after operation,25 mg,qd,continuing to take 6 months;GnRH-a group,post operative 1 week received injection of GnRH-a (Tamiflu)3.75 mg,once every 4 weeks,6 times in a row;The untreated group,fails to drug treatment.To compare the symptoms,relapse rate pregnancy rate and serum hormones including FSH, LH and E2 levels.Results After treatment, the total effective rate of GnRH-a and mifepristone group is significantly higher than the untreated group(P<0.05),and the recurrence rate is lower than the untreated group(P <0.05),the pregnancy rate is higher than the untreated groups(P<0.05).The recurrence rate,the remission rate and the pregnancy rate of mifepristone group are lower than the untreated group,there was no statistical significance.Conclusion Mifepristone and GnRH-a can both,effectively reduce the recurrence rate after EMT laparoscopic surgery,can guarantee the pregnancy rate,reduce the adverse reaction.

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.

2 months were selected. Anthropometric measurements, laboratory examinations and dietary surveys were used to assess the nutritional status. ResultsBody weight(53.714.6)kg and body mass index (BMI) (19.34.6)kg/m~2were in low normal range. Total lymphocyte counts (2.000.71)10~9/L and serum transferrin contents (1.800.44)g/L were decreased and the creatinine-height index (42.4321.82)% was obviously lower than normal range of adult. ConclusionsThese patients have energy deficiency. The changes of the mentioned parameters could be the reflection of the nutritional status of these patients and also closely related to the changes of their body composition. It is necessary to evaluate nutritional state of the elderly patients. However, the characteristics of the body composition of the elderly patients should not be ignored and a global assessment is needed.

Chemokine CXCL9/Mig (monokine induced by IFN-?) belongs to the subfamily of chemotactic cytokines known as CXC-chemokines. In vivo CXCL9 is mainly induced by IFN-? in macrophages and primary glial cells. In vitro, CXCL9 can be secreted by cells such as macrophages, microvascular endothelial cells and neutrophils, in response to the synergy of IFN-? and TLR(toll-like receptor) ligands. CXCL9 is a chemoattractant for activated T lymphocytes, tumor-infiltrating T-lymphocytes, but not for neutrophils or monocytes. The receptor specific for CXCL9 is CXCR3, a G protein-coupled protein which has seven transmembrane domain. The structure and the chemical characterization of CXCL9, as well as its effects on autoimmune deseases, allograft rejection, cancer therapy were reviewed.

Objective To investigate the expression and significance of Toll-like receptor 4(TLR4)in the uvea of endotoxin in- duced uveitis.Design Experimental study.Participants 12 Wistar rats were divided into two groups at random,a group(n=6)of endo- toxin induced uveitis(EIU)and a control group(n=6).Methods Cholera vibrio was injected into hind footpad and abdominal cavity in the EIU group.In the control group,cholera vibrio was replaced by PBS.Anterior segment of the rats eyes were observed by slit lamp microscope at 4h,10h,16h,24h after injection.Immunohistochemical staining was performed using polyclonal antibodies to TLR4 on the frozen sections of the eyes and uveal wholemounts at 24 hours after LPS injection.Main Outcome Measures The inflammation of anterior segment and the number of TLR4 positive cells in uveal wholemounts.Results The inflammation began at 4h after LPS injec- tion.Cellulose exudates were observed at 16h after injection.The positive-stained protein located in cellular membrane or cytoplasm. The number of TLR4 positive cells in EIU group is evidently higher than that in the control group.TLR4 positive cells were hardly de- tected in the frozen sections of eyes.Conclusion TLR4 expression increases in the EIU,which suggests that TLR4 probably participates in the formation and development of acute anterior uveitis.(Ophthalmol CHN,2008,17:48-51)

Objective To explore the relationship between serum Cystatin C (CysC) ,hypersensitive C-reactive protein (hs-CRP) level and the carotid intima-media thickness(IMT) in patients with type 2 diabetes mellitus(T2DM) .Methods 85 patients with T2DM were divided into two groups according to IM T level :Normal IM T group and IM T increased group .40 healthy people were chosen as control .The level of CysC and hs-CRP were measured and IMT of the carotid artery was determined by color Doppler ul-trasonography in 85 diabetics and 40 normal subjects .Results The CysC levels in IMT increased group was higher than normal IMT group and control group(P<0 .05) .The hs-CRP level in IMT increased group was higher than that in the normal IMT group and control group(P<0 .01) .The analysis of correlation indicated that the level of hs-CRP had positive correlation with IMT .And there was no association between serum CysC level and carotid IMT (r=0 .104 ,P>0 .05) .Conclusion There is no definite correla-tion between serum CysC level and carotid IMT in patients with type 2 diabetes mellitus .Serum CysC level is not predictive index in carotid intima-media thickness of T2DM .Inflammatory play an important role in early carotid atherosclerosis in patients with T2DM .
