Objective To study the changes of quantitative expression,adhering activity and genomic density polymorphism of complement type 1 in erythrocytes (CR1) of patients with liver cancer (104 patients) and their clinical significance.Methods Polymerase chain reaction (PCR),HindIII restriction enzyme digestion,the quantitative assay of ECR1 and the adhering activity assay of CR1 in erythrocytes were used.Results No difference was observed between the patients with liver cancer (29.8%) and healthy individuals (25.3%) in the spot mutation rate of CR1 density gene (χ2 =0.537,P>0.05).The number and the adhering activity of CR1 in patients with liver cancer (0.83±0.22 and 47.1±6.5) were significantly lower than those in healthy individuals (1.26±0.33 and 62.4±7.6; t=10.5,P<0.0001).The number and the adhering activity of ECR1 in high expression genomic type (HH) liver cancer were obviously lower than those of healthy individuals,expecially those of the patients with advanced liver cancer.There was a good relationship between quantitative expression,adhering activity of ECR1 and liver cancer development.Conclusion Defective expression of CR1 in liver cancer is mostly acquired through central peripheral mechanisms.The changes of CR1 quantitative expression and adhering activity are consanguineously related to the severity and the activity of the development in patients with liver cancer.

Aim To investigate total flavones of epimedium (TFE) modulation of glycine-activated current (IGly) in acutely dissociated rat spinal dorsal horn neurons. Method Whole-cell patch-clamp technique was used. Result TFE inhibited IGly reversibly in a concentration-dependent manner. It shifted the concentration-response relationship to the right without altering the maximum response and Hill coefficient of the IGly. TFE did not change the ion selectivity of glycine receptor either. Conclusion These results indicate that TFE directly inhibited the glycine receptor response by decreasing the affinity of glycine to its receptor.

Objective To investigate renal expression of ApoE in human lupus nephritis (LN) and its relationship with renal damages.Methods Renal expression of ApoE was examined in 40 LN patient biopsy samples by immunohistochemieal staining.The relationship between ApoE levels" and renal pathologic changes,renal injuries was analyzed.Results Only weak ApoE expression was found in normal renal tissue.The expression of ApoE was significantly higher in LN patients [ glomerular:(31.2±11.0) vs (3.0±1.6);tub-ular:(71.64±8.90) vs (0.60±0.06)].The expression of ApoE was higher in class IV than non-class IV LN [glomerular: (38.4±4.5) vs (18.0±4.6);tubular: (77.6±2.5) vs (60.0±3.2)].Spearman's relation-ship analysis showed that the expression of ApoE in glomerular and tubular was closely related to the renal histological score activity index and functional changes in LN (P<0.01).Conclusion The expression of ApoE is high in renal tissues of LN,especially in class IV,and the high expression may be associated with LN activity and progressive renal dysfunction.

BACKGROUND:Bone marrow mesenchymal stem cel transplantation is considered as a promising therapy for spinal cord injury. How to more effectively promote the survival of bone marrow mesenchymal stem cel s in the area of spinal cord injury and to accelerate the recovery of motor function after spinal cord injury is a current study focus. Previous studies have found that low-frequency electromagnetic fields can promote bone marrow mesenchymal stem cel proliferation and differentiation, but whether the low-frequency electromagnetic fields can be applied to bone marrow mesenchymal stem cel transplantation for treatment of spinal cord injury requires further studies. OBJECTIVE:To discuss the effects of low-frequency electromagnetic fields on motor function of spinal cord injury rats after transplantation of bone mesenchymal stem cel s. METHODS:Sixty-four rat models of incomplete spinal cord injury at T 10 were established by compression method and then randomized into control group, transplantation group (bone mesenchymal stem cel transplantation), electromagnetic field group and combination group (electromagnetic field+bone mesenchymal stem cel transplantation). After successful modeling, bone mesenchymal stem cel s labeled with 5-bromo-2'-deoxyuridine were injected into the original injured site in the transplantation group and combination group, which were isolated and purified with the fast adherence method;while alpha-minimum essential medium was injected into the electromagnetic field group and control group for instead. At 24 hours post-operation, the electromagnetic field group and combination group were explored to low-frequency electromagnetic fields (frequency 50 Hz, magnetic indaction intensity 5 mT) for 60 minutes per day. RESULTS AND CONCLUSION:After cel transplantation for 21 days, the Basso, Beattie, and Bresnahan scores in the combination group was higher than the other groups (P<0.05). 5-Bromo-2'-deoxyuridine positive cel s grew wel , and integrated into the normal spine;syringomyelia was reduced, and the number of spinal neural cel s was increased in the combination group. In addition, glial fibril ary acidic protein expression was decreased in the combination group, while matrix metal oproteinase 2 expression was increased. It indicates that low-frequency electromagnetic fields could promote recovery of motor function in the spinal cord injury rats transplanted with bone mesenchymal stem cel s, which could be associated that low-frequency electromagnetic fields facilitate the survival of transplanted bone mesenchymal stem cel s, up-regulate the expression of matrix metal oproteinase 2, and reduce glial scar formation in the spinal cord injured site.

Objective To investigate the clinicopathological features and prognostic factors in patients with low grade glioma. Methods Eighty- seven patients with low grade glioma confirmed by cytological examination were retrospectively analyzed. Results Among 87 patients, male accounted for 62.1%(54/87), and the average age was 36.2 years. The average followed- up time was 51.4 months (3-135 months), and 5 cases were lost in follow-up. The follow- up rate was 94.3% (82/87). The 3- year survival rate was 84.1%, and the 5- year survival rate was 66.7%. The 3- year survival rate was related to clinical symptoms, maximum diameter of tumor and the extent of resection (P<0.01 or<0.05);and the 5- year survival rate was related to years, Karnofsky score, clinical symptoms, maximum diameter of tumor, the pathology classification and extent of resection (P<0.05 or<0.01). Conclusions Low grade glioma is more common in male patients and patients under the age of 40 years. Age below 40 years, Karnofsky score ≥ 70 scores, only epilepsy symptom, tumor diameter below 6.0 cm, oligodendrogliomas, complete resection or subtotal resection are positive prognostic factors. Postoperative radiotherapy can reduce the rate of tumor progression.

Objective To study the mechanism of restenosis following percutaneous transluminal coronary angioplasty(PTCA),and to replicate a dynamic model of cell proliferation and remoulding of vascular wall at different time points in rabbits after intimal injury.Methods The model of restenosis in common carotid artery was established by balloon injury in 70 rabbits.The indexes such as lumen area,thickness and area of intima and media,and cross sectional area bounded by the external elastic lamina(EELA) were respectively measured by computer image analysis technology at the 1st,3rd,5th, 7th,14th,28th and 35th day after the injury.Results Endothelial cells were denudated at the 1st day after injury.The proliferation of vascular smooth muscle cell(VSMC) was detected on the surface of lumen at 3 days after injury.At the 7th day after injury,the neointima was formed and continuously thicken.The thickness and area of the neointima as well as extracellular matrix were gradually increased after 14 days,and were maximal after 35 days.The thickness and area of media were also gradually increased during 3~14 days and decreased after 28 days.Compared with non-injured vessel,the medial area was obviously increased at the 14th day.The lumen area was decreased at the 5th~7th day after injury and was obviously less than that of non~injured vessel after 14 days.The EELA was gradually increased at the 1st~7th day after injury,and reached its maximum at the 14th day.The EELA was declined gradually after 28 days.Conclusion The progress of restenosis(RS) can be simulated through the model of restenosis in common carotid artery of rabbit established by balloon injury.The intimal proliferation and vascular remodeling are the leading pathogenesis of restenosis.
