Objective To explore the phenotypic characteristics of T lymphocyte subsets in the peripheral blood (PB) of Patients with rheumatoid arthritis.Methods forty-seven patients with ankylosing spondylitis (AS) and 36 health control were selected as our subjects.The patients were divided into definite Diagnosis AS group and potential AS group according to symptom and X-ray,flow cytometry was applied to measure T lymphocyte subsets and HLA-B27 of peripheral blood.At the same time,the levels of ESR,CRP and IgA were also measured.The correlation between T lymphocyte subsets and CRP HLA-B27,IgA level was analyzed.Results There was no significant difference between The definite diagnosis AS patients and healthy controls regarding of the percentages of CD3 + cells in peripheral blood,However the percentage of CD4 + cells in definite diagnosis AS patients was significantly increased than that of healthy controls (P < 0.05).The ratio of CD4 +/CD8 + cells was 3.80 ± 0.28 in AS patients,higher than that of potential AS patients.T lymphocyte subsets were showed an increase tendency as the increase the level of CRP,IgA.Conclusion Lower CD8 + cell and higher CD4 + cell were showed in the peripheral blood of AS patients,which was correlated with the disease activity and suggesting T cells might be involved in the pathogenesis process of AS.Meanwhile our data indicated that the immune response might be a susceptible factor of AS and early detection of T lymphocyte subsets might provide a diagnosis and treatment basis for diagnosis of AS.Therefore the disorder of T lymphocyte subsets might play an important role in the development of rheumatoid arthritis.

Objective To investigate the implementation and application of rotational DSA dual volume technology in displaying the intracranial artery stent.Methods Firstly,the “stent opacity”single volume technology was used to display 5 types of stent which were released in 7 cases of pure intracranial artery stenting and 12 cases of stent-assisted aneurysm embolization.Then we applied “vessel translucent”and “vessel opacity”single volume technology to display corresponding vessel segments.Finally,by coalescing the single volume imaging of stent and vessel,the “vessel opacity + stent opacity”dual volume image and “vessel translucent+ stent opacity”dual volume image were performed.We compared the effects of two kinds of dual volume imaging and assessed the imaging characteristics and influencing factors of each method.Results (1)On the “stent opacity”single volume display mode,in 7 cases of pure intracranial artery stenting,the display effect of two Pipeline stents and three Apollo stents belongs to level 1,the display effect of two Enterprise stents belongs to level 2;In 12 cases of stent-assisted aneurysm embolization,in the stent segments which weren’t influenced by artifacts,the display effect of two LEVIS stents belongs to level 1,the display effects of 5 Enterprise stents and 2 Solitaire AB stents belongs to level 2;While in the stent segments which were influenced by the artifact of spring coil and bone,the display effect significantly reduced, three pieces of Enterprise stents were even unable to identify.(2)On the “vessel opacity”single volume display mode,1 9 cases of vessel segment at the stent completed opacity display.The surface structure of vessel was very clear,but the structure under the surface was completely being covered.On the “vessel translucent”single volume display mode,the surface structure of 19 cases of vessel segment at the stent displayed clear at the tangential position.The vessel lumen also presented transparent state.(3)On the “stent opacity+vessels opacity”double volume display mode,the start-stop location and the adherence of stents in blood vessels in 1 6 cases were displayed clearly. When using the “stent opacity+ vascular opacity”double volume imaging,except 3 cases which used ball expansion Apollo stents could display comprehensive relationship between the blood vessels,in the other 13 cases,the relationship between stent and vascular could not be fully displayed.Conclusion On the condition that the single volume display technology shows stent well,the “stent opaque+vessels translucent”double volume display technology can well present the stent condition in the vessels.

Objective To investigate the status of food intolerance of patients with ulcerative colitis,(UC),to provide the basis for directing UC patients diet related nursing.Methods Forty-seven UC patients were selected from September 2013 to August 2014 in General Hospital of Tianjin University.The Southerland Disease Activity Index (DAI) was used to divide the UC patients into remission,mild activity and moderate to severe activity groups.The food-specific IgG antibodies status were tested by enzyme-linked immunosorbent assay in UC patients and healthy people.Relevant clinical parameters were analyzed statistically.Results Food intolerance rate in UC patients was as high as 68.08%(32/47);the food species:egg,wheat and milk ranked the most frequently intolerance food.The food intolerance rates in remission,mild activity and moderate to severe activity groups were 9/16,11/18,12/13,there were significantly different,x2=7.418,P<0.05.Extraintestinal manifestation group had significantly higher food intolerance rate compareed to non extraintestinal manifestation group:1 1/13 vs.55.88%(19/34),x2=2.234,P<0.05.No significant difference of food intolerance rate were showed among groups categorized according to sex,age,body mass index,site of lesion,P>0.05.Conclusions UC patients show higher food intolerance rate than healthy people.UC disease activity and extraintestinal manifestations are correlated to food intolerance,which is of great significance to guide diet related nursing of UC patient.

Objective To evaluate the influence of grape seed proanthocyanidin extract (GSPE) on sunburn cell formation and p53 protein expression induced by acute ultraviolet injury. Methods Ten volunteers were enrolled in this study. The buttock region served as the exposed region. Four areas were randomized and delineated on the buttock: one area (control area) received no exposure or product, the other 3 areas were exposed to two minimal erythema doses (MED) of simulated solar radiation (SSR) for 3 days. Of the 3 exposed areas, one area (SSR) received no product before exposure, one area (SSR + Veh) was pretreated with vehicle, the third area (SSR + GSPE) with the samples of GSPE. GSPE or vehicle was applied 30 minutes before each exposure at 2 μL/cm2. Skin biopsy was performed 24 hours after the last exposure, and skin specimens were subjected to hematoxylin eosin (HE) staining and histochemical analysis for p53 protein. Results There was a statistical difference in the number of sunburn cells per high power field (×200) between SSR sites and SSR + GSPE sites (29.8±11.1 cells vs 2.2±0.2 cells, P<0.01). A significant decrease was noticed in the account of p53 protein-positive cells per high power field (×200) in SSR + GSPE sites com-pared with the SSR sites (4.6±0.7 cells vs 19.3±3.4 cells, P<0.05). Conclusion GSPE exerts a poten-tial protective effect against acute ultraviolet injury and can serve as a natural sunscreen.

Based on the competition reaction of target protein, aptamer probe, padlock probe and complementary sequence, a highly sensitive fluorescent aptasensor was developed in this study in combination with rolling circle amplification. In the absence of target protein, the ligation-rolling circle amplification reaction was repressed because the complementary sequence hybridized with aptamer probe to form double-stranded duplex. While in the presence of target protein, the target molecules bound specifically with aptamer probe, inducing displacement of the complementary sequence and hybridization with padlock probe. The padlock probe was circularized with the assistance of E. coli DNA ligase, and the rolling circle amplification process could be accomplished by Phi 29 DNA polymerase. The amplification product contained thousands of repeated sequences which could hybridize with the loop of molecular beacon ( the detection probes) , resulting in a significant fluorescence signal. The effects of length of complementary DNA ( CDNA ) sequence and concentration of padlock probe were investigated. Under the optimized experimental conditions, the model target protein thrombin could be highly sensitively detected by the proposed aptasensing system in a linear range of 0 . 067-32 . 4 nmol/L with a detection limit of 0 . 03 nmol/L ( approximately 90 amol target molecules). Moreover, the presented sensing method was universal for other target analysis by skillfully design of the sequence of aptamer probe and related oligonucleotides.
