Pituitary stalk interruption syndrome(PSIS) is a rare disease characterized by different degrees of anterior pituitary hormone deficiency.The typical imaging finding is a thin or absent pituitary stalk,often associated with an ectopic posterior pituitary and a hypoplastic anterior pituitary.The cause is still unkown.Dynamic contrastenhanced MRI helps to confirm the diagnosis.Replacement of multiple anterior pituitary hormones is the key of the treatment.Doctors should have a thorough understanding of the disease and give patients efficacious treatment and a better prognosis would be obtained.

Objective To understand the clinical profiles of arthritis after human parvovirus B19(B19) infection.Methods Four cases were described and the clinical and laboratory characteristics were analyzed. Results The median onset age of the 4 patients(2 females and 2 males)was 34 years old.Typical clinical manifestations included joint symptoms,flu-like malaise and erythematous rash.Anti-Bl9 IgM antibodies were all positive in 4 patients.B19 DNA was detected in blood samples of 3.Other types of arthritis were excluded. No relapses were noticed after followed-up of 1~3 years.Conclusion The Anti-B19 lgM and B19 DNA should be detected in patients suffer from arthritis with unknown origin.

Objective To investigate the effect of rivaroxaban on prevention from deep venous thrombosis after hip replacement surgery .Methods 80 patients with lower limb parallel arthroplasty were randomly divided into observation group and control group from January 2014 to January 2015.40 cases in each group.Control group was given aspirin treatment, observation group was given rivaroxaban treatment, indicators changes were followed up and recorded.Results PT, APTT values of observation group one week after treatment were (35.79 ±2.16),(15.84 ±2.11) s, which were better than control group (45.64 ±2.12),(18.72 ±2.02) s (P<0.05).TT, D-dimer of observation group(13.48 ±2.10)s,(2.34 ±0.33)g/L after a week were better,than control group (16.38 ±1.79)s, (1.42 ±0.21)g/L (P<0.05) respectively.Conclusion Effect of rivaroxaban in prevent deep venous thrombosis after hip replacement surgery is exact without obvious adverses reaction, it is worthy of further research and application.

Objective To determine the effect of the combined use of urokinase and glycoprotein Ⅱb/Ⅲa-targeted microbubbles prepared by direct conjugation method to dissolve the thromb in vivo and analyse the velocity tracing change of blood flow and explore the possible mechanism. Methods A total of 42 rabbits with platelet-rich thrombi in the femoral artery were randomized into 7 treatment groups ( n = 6 in each group): 1) ultrasound alone (US); 2) ultrasound plus non-targeted microbubbles ( US + M); 3) urokinase alone (UK) ;4) ultrasound, non-targeted microbubble and urokinase (US + M + UK); 5) ultrasound plus platelet-targeted microbubble ( US + R); 6) platelet-targeted microbubble plus urokinase (R + UK); 7)ultrasound, platelet-targeted microbubble and urokinase (US + R + UK). A total of 6 ml of infusion liquor of Urokinase,RGDS and microbubbles (SonoVue) were mixed by 1 ∶ 1 ∶ 1 ratio by the direct conjugation method, infusion via vein within 20 min. Ultrasound was conducted to lyse the clot for 30 min. The recanalization and the velocity tracing change of blood flow in thrombolytic process were evaluated at 120 min post treatment. Results For US, UK, US + M, US + R and US + M + UK groups, recanalization was failed. The R + UK and US + R + UK was recanalizated ( P <0.001 ). The blood flow velocity tracing was small and low width in US,UK, US + M, US + R and US + M + UK groups. The wave was high width and disorderly under the thrombolysis therapy in the R + UK and US + R + UK. The thrombolytic effect was demonstrated by the high-width and disorderly resonance changes in the blood flow spectrum during the thrombolytic therapy of US + R + UK. Conclusions The blood flow spectrum of groups had different characteristics in vivo when thrombus was issolved,ultrasonic resonance might be the possible mechanism.

Objective To investigate the value of ultrasonography in evaluating the femoral artery thrombosis in rabbit. Methods Thrombosis was induced by external application with 10% ferric chloride and transient femoral artery-occlusion with bulldog clamp in twenty New-Zealand rabbits. The thrombosis was monitored by both Doppler flowmeter and ultrasonography. The histopathological result was used as the golden standard. The consistency of the above two results with the golden standard was analyzed. Results Thirty-two femoral arteries thrombosis were produced successfully. There was high consistency between the results of ultrasonic evaluation and histopathological examination (Kappa = 0. 720, P < 0. 001 ), and moderate consistency between the results of Doppler flowmeter evaluation and histopathological examination (Kappa = 0. 546, P <0. 001 ). Within the thirty-two femoral arteries thrombosis, there were nineteen arteries with occlusive thrombus examined by histopathological means. Both the results of Doppler flowmeter and ultrasonography were highly consistent with the results of histopathological examination (Kappa = 0. 800 and 0.798 respectively, P < 0. 001 ). Conclusions There is high consistency between the results of ultrasonic evaluation and histopathological examination for the common femoral artery thrombosis in rabbit.In the non-occlusive thrombus diagnosing,ultrasonography is better than Doppler flowmeter.

Objective To investigate the specific anti-tumor immune response induced by dendritic cells (DCs) transfected with total RNA of human pancreatic cancer Capan-2 cells.Methods DCs were isolated and cultured from peripheral blood mononuclear cells (PBMCs) derived from six patients with pancreatic cancer.Total RNA of Capan-2 cells and MUC4 mRNA were transfected into DCs by electroporation.The survival rate of transfected DCs was determined by MTT method and the expression of MUC4 mRNA in DCs was detected by Western blotting.The activity of cytotoxic T lymphocyte cells (CTLs) induced by DCs transfected with total RNA of Capan-2 cells were evaluated by IFN-γ ELISA and the induction of specific CTL response to the killing effect on pancreatic cancer cell in vitro were measured by 51 Cr standard cytotoxicity test.Results The survival rate of DCs transfected with total RNA of Capan-2 cells (DC-Capan-2-total RNA) showed a decrease in a time dependent manner and the survival rate was reduced to 60.81% after transfection for 96 h.The survival rate of MUC4 mRNA transfection DCs (DC-MUC4 mRNA) was stable at around 80%.The difference of DCs surviral rate between the two groups was statistically significant (P < 0.05).The amount of MUC4 protein expression of DC-Capan-2-total RNA was significantly lower than that of DC-MUC4 mRNA (P <0.05).The quantity of CTL IFN-γ release induced by DC-Capan-2-total RNA was (89.34 ± 3.85)U/mL and the quantity of DC-MUC4 mRNA induced CTL IFN-γ release was (21.77 ± 21.77)U/ml There was statistically significant between the two groups (P <0.05).In addition,the specific CTLs induced by DC-Capan-2-total RNA could effectively identify and kill the HLA-A2+/MUC4+ Capan-2 and the HLA-A2+/MUC4-PANC 1 cells,and could not effectively identify and kill the HLA-A2 /MUC4-MiaPaCa-2 cells and the HLA-A2-/MUC4 + AsPC-1 cells.Conclusions A more pronounced CTL anti-tumor immune response can be induced by DCs transfected with total RNA of Capan-2 cells compared with a single tumor associated antigen,but it is limited by MHC class Ⅰ antigen presented.
