To study the effect of urokinase on platelet activation and aggregation in the patients with glomerulonephritis. Platelet counts(PC),mean platelet volume (MPV), and platelet distribution width (PDW) were determined with automatic blood cell analytic apparatus, the expressive levels of platelet granular membrane protein (GMP 140) and fibrinogen receptor(GPⅡb Ⅲa) on the surfaces of platelets were assayed with flow cytometry, and the levels of fibinogen and fibrin degradation products (FDP) in blood were measured with ELISA in 102 children with glomerulonephritis. The results showed that urokinase led to PC decreas,MPV increase and PDW exceeding normal value in 102 children with glomerulonephritis, including micro change (MC),glomerulosclerosis (GS),membranous nephropathy (MN), and proliferative glomerulonephritis (PGN).The expressive levels of GMP 140 after the treatment with urokinase were significantly higher than that before the treatment and controls( P 0 01). The results suggested that urokinase used in the patients with glomerulonephritis increased platelet activation function and decreased platelet aggregation function.

BACKGROUND:Neural stem cel transplantation has been used to treat a series of brain injury diseases, such as cerebral palsy, but its effect on Alzheimer’s disease is rarely reported. OBJECTIVE:To observe the effect of neural stem cel transplantation on the behavior and immune regulating system of Alzheimer’s disease rats. METHODS:Thirty-five Sprague-Dawley rats were enrol ed to make a postcerebral incision and given hippocampal injection of amanita phal oides acid to establish rat models of Alzheimer’s disease. Another 10 rats were only given hippocampal injection of normal saline after preparation of postcerebral skin incision as sham operation group. Then 32 successful rat models were randomly divided into two groups (n=16 per group):rats in experimental group were administrated hippocamal injection of 5×109/L al ogeneic neural stem cel suspension;those in model group were given no injection. Five-day Morris water maze test was conducted at 4 weeks after transplantation. At 1 week after Morris water maze test, levels of interleukin-1 and interleukin-10 in the cerebral homogenate were detected, as wel as pathological changes of brain tissues were observed in the three groups. RESULTS AND CONCLUSION:Compared with the model group, the abilities of cognition and memory were significantly higher in the sham operation group (P<0.01), and the abilities of spatial learning and memory were significantly higher in the experimental group (P<0.05, P<0.01). Levels of interleukin-1 and interleukin-10 in the model group were significantly higher than those in the sham operation group (P<0.01) but significantly lower than those in the experimental group ( P<0.01). Besides, the number of neurons in the model group was obviously less than that in the experimental and sham operation group. These results indicate that neural stem cell transplantation supplements and protects neurons against Alzheimer's disease in rats, thereby significantly improving the learning and memory ability.

Objective:To explore the role CD4+CD45RO+memory T cells in the pathogenesis of Hashimoto's thyroiditis (HT) by detecting the percentages of CD4+CD45RO+ memory T cells in peripheral blood mononuclear cells in peripheral blood of newly diagnosed HT patients. Methods:53HT patients and 43 matched healthy controls (HC) were included in this study. According to the thyroid functions,HT patients were divided into euthyroid subset(HT-A,n =15) ,subclinical hypothyroidism(HT-B,n=14) and overt hypothyroidism subset (HT-C,n=24). The percentages of CD4+CD45RO+memory T cells in PBMCs,as well as the level of serum IFN-γ and IL-17,and thyroid functions,and the titers of thyroid-specific autoantibodies (TPOAb,TgAb) were respectively detected by flow cytometry,ELISA,and ECLIA. Results:The percentages of CD4+CD45RO+ memory T cells in PBMCs,as well as the level of serum IFN-γ and IL-17,the titers of TPOAb,TgAb were all significantly higher than that in HC(P<0. 01). Bivariate correlation revealed that the percentages of CD4+CD45RO+ memory T cells positively correlated with the level of serum IFN-γ,TPOAb and TgAb(P<0. 01,P=0. 015,P<0. 01) in HT patients. Conclusion:The significant increase of CD4+CD45RO+memory T cells in peripheral blood of patients with HT suggested a role of CD4+CD45RO+ memory T cells in the pathogenesis of this disease.

Objective To establish an experimental retinal artery occlusion (RAO) model by means of photochemistry therapy with 532 nm frequency-doubled laser, and to evaluate the feasibility of this method. Methods Ten eyes from ten healthy adult New Zealand rabbits were intravenously injected 5% rose bengal solution, then their monocular retinal artery was irradiated by 532 nm frequency-doubled laser. Both eyes of these rabbits were examined by direct ophthalmoscope and fundus photographic camera on the 1st hour, 24th hour and 3rd day. Meanwhile, the experimental eyes were examined by fundus fluorescein angiography (FFA). These rabbits were killed on the 3rd day, experimental eyes were enucleated, the retina was observed under light microscope. Results There were 9 eyes approved having RAO by direct ophthalmoscope and FFA. Thrombi in retinal arterials could be found by light microscope in all these 9 experimental eyes, and the walls of blood vessel were intact without any obvious necrosis or attenuation. Conclusions RAO animal model can be induced by photochemistry therapy with 532 nm frequency-doubled laser. There are thrombi in the retinal artery without trauma of the artery wall. Photochemistry therapy is an efficient, secure and reproducible method to induce animal model of RAO.
