ObjectiveCurrently,adsorption materials applied to remove low density lipoprotein (LDL) still remain defects.HB-H-8 resin has not been put in use in removing LDL.This study focused on primary evaluation of adsorption capability of HB-H-8 resin.MethodsHB-H-8 resin was used in the adsorption of LDL of patient that was higher than the normal range of blood sample in dynamic test and static test in vitro.ResultsThe time of adsorption saturation was two hours,and the optimum temperature was 37℃.The results of adsorption in vitro showed that the average adsorption rates of LDL and high density lipoprotein (HDL) were 63.2％ and 1.9％,respectively.ConclusionHB-H-8 resin has LDL higher adsorption capability,thus made it to be a potential blood purification material for the removal of LDL.

To investigate the effect of estrogen receptor (ER) agonist 17β-estradiol and G protein-coupled estrogen receptor 1 (GPER) agonist fulvestrant on masangial cell fibrogenesis under protein kinase C (PKC),we quantified type Ⅳ collagen (COL4A1),fibronectin (FN1),connective tissue growth factor (CTGF) and transforming growth factor-β1 (TGFβ1) gene transcription and semi-quantified phosphorylation of Akt signal upon Phorbol 12-myristate 13-acetate stimulation (which increased COL4A1,FN1,CTGF and TGFβ1 gene transcription to 2.5-0.5,1.4 ±0.2,26 ± 11 and 1.9 ±0.3 times compared with baseline,P ＜0.05) when incubated with the two drugs.It was found that 17β-estradiol and fulvestrant down-regulated COL4A1,FN1,CTGF and TGFβ1 genes transcription (P ＜0.05) and Akt signaling under PKC activation via ER and GPER.ER and GPER agonists are beneficial in protecting the mesangial cells from fibrogenic stimuli by inhibiting PKC signaling and excessive extracellular matrix production.

Patients who complained of pain, tenderness mass in neck, fever, limitation of mouth opening, pharyngalgia,dysphagia,with lab showing increased Neu, remarkably decreased PLT, upsurging Glu, urine-Glu, ALT, T-Bil, AFP, were finally diagnosed to suffer from deep neck abscesses after CT scanning. What was worth mentioning was that diabetes, hepatitis C, thrombocytopenia, and fungus infection added to the complexity of the treatment.

Objective To investigate the effects and the possible mechanisms of nerve growth factor (NGF) on serum levels of vascular endothelial growth factor (VEGF) and stromal cell-derived factor 1 (SDF-1) protein expression in rats with focal cerebral ischemia.Methods Male Sprague-Dawley rats weighting 200 ～ 250 g were subjected to middle cerebral occlusion (MCAO).MCAO rats were randomly divided into NGF group,saline control group and NGF+PI3K antagonist group (n =12).The neurological function was evaluated on the 4th,7th day after MCAO,and the serum levels of VEGF and SDF-1 protein were measured by ELISA.Results The neurological function was better in rats of the NGF group than those of the saline control group and NGF+PI3K antagonist on the 4th,7th day after MCAO (P ＜ 0.05).The serum levels of VEGF and SDF-1 protein of the NGF group was significantly higher than that of the saline control group and NGF+PI3K antagonist group on the 4th day after MCAO (P ＜ 0.05).Conclusions Treatment with NGF may improve neurological function of rats with focal cerebral ischemia,and upregulate serum levels of VEGF and SDF-1 protein expression.PI3K/AKT signal pathway may have attended the above regulation.

Hemoperfusion is a kind of medical device which contacts directly with blood.In the application,fully considering the interaction between the blood and the sorbent material,so as to improve the blood compatibility is particularly important.With the development of medical science,chemistry and biomedical engineering,a variety of new materials of hemoperfusion have been studied and the blood compatibility of hemoperfusion sorbent has also been greatly improved,making the range of hemoperfusion clinical applications increasingly wide.This paper,combining related research results in recent years,reviews the research progress of the hemoperfusion adsorbent's blood compatibility in recent years.

Objective To describe CT and MRI findings of the global choroidal hemangioma, and to investigate their value in the diagnosis and differentiation. Methods Nine choroidal hemangioma patients proven by surgical pathology( n =3)or clinic information ( n =6) were analyzed. CT scan was performed in 6 cases and MRI in 4 cases. All cases were examined by ultrasound and 3 with fundus fluorescein angiography (FFA). Results Two cases showed slight or crescent like thickening and iso density with respect to the global wall on CT scan. 5 cases on enhanced CT showed a flat or shuttle shaped homogeneous mass with marked enhancement. MRI ( n =3) revealed high signal intensity on T 1WI and low signal intensity on T 2WI with respect to the vitreous. 1 small tumor was found clearly by postcontrast fat suppressed T 1WI. Ultrasound showed homogeneous mass ( n =1) and inhomogeneous mass ( n =8), with retinal detachment in all cases. Conclusion CT + MRI + ultrasound can get most of the diagnostic imaging data for choroidal hemangioma. MRI was superior to CT and ultrasound in the diagnosis of choroidal hemangioma and differential diagnosis from other malignant tumors.

Objective The aim of this article was to deeply study the effects of different molecular weight of proteins and different structures of chemical substances on the adsorption specificity of HB-H-6 resin.Methods HB-H-6 resin was adopted to adsorb 5 different molecular weight proteins and different structural chemical substances including proteins,saccharides,human serum albumin (HAS),dextran and lipid,and then underwent static adsorption experiments in vitro.The adsorption rates of different structural chemical substances were analyzed from two experiments and the results were compared.Results The experiment results of HB-H-6 resin adsorption showed that the average adsorption rates of 5 different molecular weight proteins,myoglobin (Myo,16 700),ovalbumin (OVA,44 000),HAS (66 200),β-gal (130 000) and IgG (150 000),were significantly different:(0.00±0.33)％,(8.02± 1.23)％,(43.19±2.31)％,(34.25±1.07)％ and (0.00±0.69)％.In the studies on adsorption of different structural chemical substances,the average adsorption rates of different structural chemical substances proteins,saccharides,lipid were significantly different:the absorption rates of plasma total protein,albumin,globulin,glucose,triglyceride and cholesterol groups were:(11.18±0.72)％,(10.74±0.66)％,(11.74± 1.22)％,(7.17±0.12)％,(1.06± 1.04)％,(3.05± 0.65)％.The absorption rates of HAS and dextran groups were:(43.19±2.31)％ and (5.44±1.46)％.Conclusion In conclusion,the proteins' molecular weight of best adsorption condition is from 66 Ku to 130 Ku.The average adsorption rates of different structural chemical substances proteins,saccharides,lipid are significantly different.The average adsorption rates of proteins are higher than that of saccharides and lipid.It shows that HB-H-6 resin has adsorption specificity on different molecular weight proteins and different structural chemical substances.
