Objective To summarize the initial application of three dimensional angiography(3D angio) in the diagnosis of carotid stenosis and carotid stenting.Methods 23 patients with carotid stenosis confirmed by conventional angiography (two dimensional angiography, 2D Angio) received 3D Angio including 16 accepted both 2D Angio and 3D Angio before and after carotid stenting and then undengone comparative study. Results 32 stenosed lesions were found, including 5 in common carotid artery, 19 in neck section of internal carotid artery, 3 in patrous section, 2 in caverous sinus and 3 in middle cerebral artery. 3D Angio could demonstrate the changes of stenosed segment from every point of view. The degree and extent of stenosis could be accuratly evaluated. The characterization of lesions including the diminution of lumen and coarse plaques could be clearly displayed. After stenting, the wall of stenosed segment became smooth and the plaques disappeared.Conclusions The diagnosis and treatment of carotid stenosis by 3D Angio is helpful to accurately estimate the extent of stenosis, the characterization of the lesions and monitor the results of stenting.

Objective To establish stable Graves disease (GD) mice models with immunization and electroporation (EP).Methods Fifty mice were divided into 3 groups by random number table method:experimental group (n =30),control group (n =10),blank group (n =10).Recombinant plasmid pcDNA3.1/hTSHR268 was constructed and injected to bilateral gastrocnemius in experimental group mice on the 1st,4th,7th and 10th week.The same volume of normal saline was injected in the control group and blank group at the same time.Both experimental group and control group were subjected to EP at the same time and the same location to enhance immunization.Serum T4 was tested with radioimmunoassay.TRAb N-terminal (TRAb N) and TRAb C-terminal (TRAb C) antibodies were tested with ELISA.Whole body 99TcmO4-imaging was performed and then thyroid morphology and pathology were investigated.Data were analyzed by one-way analysis of variance and the least significant difference (LSD) t test.Results GD BALB/c mice models were built successfully (80％,24/30).Serum T4 increased from (16.06±5.16) nmol/L at the basic level to(95.04±68.92) nmol/L on the 12th week(F=18.906,t=-5.598,P＜0.05).Serum TRAb N antibody increased from (0.006±0.002) U/L at the basic level to (0.251±0.110) U/L on the 12th week(F=47.491,t=-10.869,P＜0.05).Serum TRAb C antibody increased from (11.176±2.635)×103 arbitrary unit (AU)/L at the basic level to (46.395±22.001)× 103 AU/L on the 12th week(F=14.642,t =-7.787,P＜0.05).On the 18th week serum T4,TRAb N and TRAb C decreased to (36.64±23.68) nmol/L,(0.094±0.053) U/L and (24.456±6.725)× 103 AU/L respectively,which were still higher than those preimmune levels(t=-4.161,-8.085,-9.008,all P＜0.05).There were no significant change of T4,TRAb N and TRAb C in the control group and blank group.After 4 times of immunization,the 99TcmO4-uptake by thyroids in immunized mice increased.The thyroid glands of immunized mice showed enlargement.Microscope examination showed that there were lymphocytes infiltration,colloid decrease and epithelial cell proliferation in thyroids of immunized mice.Conclusion GD mice models were successfully established by injecting recombinant plasmid pcDNA3.1/hTSHR268 and EP.

Objective To investigate the CT imaging features of urinary tract ceftriaxone-associated pseudolithiasis.Methods The CT imaging data of three patients with ceftriaxone-associated pseudolithiasis were collected from August,2008 to April,2012.Their data combined with related literatures were used to review CT imaging features of urinary tract pseudolithiasis.Those three patients,including 2 males and 1 female,were 9,21 and 55 years old,respectively.Ceftriaxone sodium was administrated to one patient due to appendicitis and the other two patients due to urinary tract infection.After ceftriaxone treatment,1 case began to have backache and abdominal pain on day 13,1 case presented backache with floc in the urine on day 2 and progressed to anuria,and the other one had cotton-like material in the urine on day 5.Urinary tract high density shadows were found in all patients by CT scan.The patient with anuria was treated with ureteroscopic lithotripsy and percutaneous nephrolithotomy.The other 2 cases were arranged to be followed up with CT scan.In those cases,the CT showed that the high density shadow in one patient disappeared 16 days after drug discontinuation.The high density shadow was significantly reduced 12 days after ceftriaxone withdrawal in the other one.However,no follow-up was performed afterwards.Results All the urinary tract ceftriaxone-associated pseudolithiasis presented the high density shadows on CT,with CT value 47-667 HU.The density of CT results is homogenic,except one ureteral stone.The pseudolithiasis,existed in kidney,ureter and bladder simultaneously,were found in two patients.And the other patient was found that the pseudolithiasis existed in both kidney and bladder.Two cases were accompanied with hydroureter and hydronephrosis and the other case were accompanied with cholecystolithiasis.The multiple renal pseudolithiasis was noticed in 2 cases,which exhibited the nodular shape.And one patient with hydronephrosis presented both sand-like and nodular stones.Ureteral pseudolithiasis was found in 1 case with 4 stones and the other one with 2 stones.In those pseudolithiasis,5 appeared column morphology and one showed nodular shape.The single nodular stone in bladder was found in one case.And the multiple bladder stones were found in 2 cases.Conclusions The CT imaging characters of urinary tract ceftriaxone-associated pseudolithiasis are high homogenic density shadows in multiple parts of bilateral urinary tracts.The ceftriaxone-associated pseudolithiasis is column shape in ureter and sand-like or nodular shape in kidney and bladder.

Objective To establish the normal reference ranges of peripheral blood CD4 and CD8 lymphocytes for the healthy population in Tianjin. Methods 366 samples were recruited from among local physical examination adults and their absolute and proportional values for the ranges of CD4 and CD8 lymphocytes were detected by quantitative flow cytometry with fluorescence labeled antibodies. Results Mean absolute values were (860.27?255.15) cells/?l for CD4 T cells,(671.60?371.39) cells/?l for CD8 T cells and (1.44?0.62) for CD4/CD8 ratio; and the proportional values were (37.05?7.42)% for CD4 T cells,(28.42?7.46)% for CD8 T cells. Our results showed no differences between gender and age on CD4 T cell counts among the healthy adult population in Tianjin. Conclusions There is difference in CD4 T lymphocyte counts in different areas.

Background Researches showed that thymic stromal lymphopoietin (TSLP) is an interleukin-17-like inflammatory factor and plays important roles in the pathogenesis and development of allergic diseases.However,the study whether TSLP plays roles in allergic conjunctivitis is rare.Objective This study was to investigate the expression change of TSLP and IL-4 in ocular surface tissue and cervical lymph node in the mice with allergic conjunctivitis induced by artemisia annua,a common plant in China,and to explore the role of TSLP and IL-4 in the pathogenesis and development of allergic conjunctivitis.Methods Twenty female BALB/c mice aged 6-8 weeks were randomized into normal control group and model group.Antigen solution was prepared using 400 μl extracting solution of artemisia annua pollen with 400 μl antigen solvent.The mouse models of allergic conjunctivitis were established by injection of 50 μl antigen solution in footpad followed by ocular topical administration of extracting solution once a day from day 10 to 12 after injection,and no any intervention was given in the normal control group.The mice were sacrificed and eyeballs were obtained 13 days after modeling,and corneal epithelium,conjunctiva and cervical lymph nodes were harvested for the detection of TSLP mRNA and IL-4 mRNA by real-time PCR.Immunochemistry was employed to assay the expression of TSLP and IL-4 proteins in corneal,conjunctival and subconjunctival tissues.Results Ocular inflammatory signs appeared 0.5 hours after ocular topical administration of extracting solution,including eyelid edema,conjunctival congestion,tears,scratching eyelids,etc.The symptoms lasted for 6-24 hours,with the model successful rate 80％.Real-time PCR indicated that the expression of IL-4 was absent in corneal epithelium in both model group and normal control group.The relative expression levels of TSLP mRNA in the corneal epithelium,conjunctiva and cervical lymph nodes in the model group were more (1.63±0.20)times,(2.71±0.48) times and (1.48 ±0.05) times than the normal control group,showing significant differences between the two groups (t =4.44,14.16,5.01,all at P＜0.05).Compared with the normal control group,the relative expression levels of IL-4 mRNA in the model group increased (2.94±0.39) times and (1.74±0.09) times,with significant differences between the two groups (t =9.92,14.54,both at P＜0.05).Immunochemistry assay showed that the expression of TSLP protein in the corneal and conjunctival epithelial cells were enhanced in the model group compared with the normal control group.In addition,an intensive expression of IL-4 protein was seen in subconjunctival tissue in the model group,while the expression of IL-4 was absent in the normal control group.Conclusions TSLP is mainly expressed in the cornea,conjunctiva and cervical lymph nodes of the mice with allergic conjunctivitis,suggesting that TSLP promotes the inflammatory process of cornea and conjunctiva;IL-4 is mainly expressed in conjunctiva,showing IL-4 participates in conjunctival inflammatory process.TSLP and IL-4 play synergistic roles in promoting the inflammatory process of ocular surface in the mice with allergic conjunctivitis,which may be new therapeutic targets.

Anti-HIV drugs still remain as the dominant role in the treatment of acquired immunodeficiency syndrome (AIDS), because no vaccine was found till today. Owing to structural diversity, few side effects, and abundant resources, natural compounds from traditional Chinese medicines and medicinal plants have unique advantages and good potential in prevention and treatment of AIDS. Many researchers have made great efforts in the field of anti-HIV natural compounds, and have found some natural compounds from traditional Chinese medicines with potent anti-HIV activities. These compounds can be classified into the following categories: alkaloids, coumarins, lignans, flavonoids, terpenoids, tannins, polysaccharides, proteins and peptides, and polyphenols. However, most of these researches are performed in vitro, and most natural compounds show weak anti-HIV activities and indefinite acting targets. In the paper, we reviewed some natural compounds derived from traditional Chinese medicines with potent anti-HIV activities in recent years.
