Background:The prognosis of systemic lupus erythematosus complicated with lupus enteropathy is poor. At present, studies on pathogenesis of lupus enteropathy are rare. Aims:To investigate the expressions of intercellular adhesion molecule-1 (ICAM-1),vascular cell adhesion molecule-1 (VCAM-1)and intestinal fatty acid binding protein (I-FABP) in lupus enteropathy in mice. Methods:Twenty MRL/ lpr lupus mice were randomly divided into two groups:lupus enteropathy group and control group. Lupus enteropathy model was established by administration with TNBS enema. Histological score was assessed,expressions of ICAM-1,VCAM-1 and I-FABP were determined by immunohistochemistry, and correlations with histological score were analyzed. Results:Compared with control group,histological score was significantly increased (8. 1 ± 5. 8 vs. 0. 8 ± 0. 5,P = 0. 000),expressions of ICAM-1 (9. 4% ± 2. 1% vs. 6. 2% ± 1. 1%),VCAM-1 (15. 1% ± 2. 1% vs. 12. 2% ± 1. 9%)and I-FABP (17. 5% ± 2. 5% vs. 6. 1% ± 0. 9%)were significantly increased (P < 0. 05)in lupus enteropathy group. Expressions of ICAM-1,VCAM-1 and I-FABP in colon tissue in lupus enteropathy group were positively correlated with histological score (r = 0. 870,P = 0. 010;r = 0. 881,P =0. 010;r = 1. 000,P = 0. 000). Conclusions:ICAM-1,VCAM-1 and I-FABP may be associated with pathogenesis of lupus enteropathy.

Wnt signals widely exist in live creatures,involved in many physical or pathological processes,including the cell prolif-eration, differentiation and apoptosis. Recent studies show that Wnt/β-catenin signaling pathway may play an important regula-tory role in the protective effects of neurovascular unit in ische-mic stroke. Some chemicals,such as sulindac and estradiol,and some compound traditional Chinese medicine which contains gly-coside( e. g. rhodiola rosea ) , volatile oil ( e. g. turmeric ) and compound prescription ( e. g. Dan Long Xing Nao Fang ) can protect the neurovascular unit by regulating the pathway. This aims to review the research progress of the protective effects of Wnt/β-catenin signaling pathway on the neurovascular unit in is-chemic stroke,with combination of chemicals and traditional Chi-nese medicine which can protect the neurovascular unit via Wnt/β-catenin signaling pathway. It aims to provide the methodology basis for elucidating the mechanism of drugs,and also provide a new idea for researching the new drug which can reduce the dis-ability rate caused by sequela of stroke.

Objective To explore the effect of early comprehensive rehabilitation therapy on dysphagia after stroke. Methods A total of 120 stroke patients with dysphagia were collected from December 2006 to May 2009 and divided into 3 trial groups and a control group randomly.No treatment was given to patients in the control group.Patients in trial group 1(T1)were given rehabilitation training,while patients in trial groups 2(T2)and 3(T3)were treated with VitalStim and electrical acupuncture,respectively,in addition to the rehabilitation training.A standardized swallowing assessment (SSA) and the swallowing quality of life(SWAL-QOL) scale were used to evalu-ate all the patients before and after 4 weeks of treatment. ResuIts No statistically significant difference was re-vealed before the treatment among the groups in terms of the patients'sex,age,course of disease,SSA or SWAL-QOL results.Statistically significant improvement was observed after treatment in the 3 trial group,but not in the control group with regard to the SSA and SWAL-QOL scores compared with those before treatment.The trial groups all had higher scores than the control group after treatment.while T2 and T3 had higher scores than T1 after treatment.There was no statistically significant difference between groups T2 and T3.Conclusions Early compre-hensive rehabilitation therapy can improve swallowing and the quality of life of stroke patients with dysphagia.Reha-bilitation combined with neuromuscular electrical stimulation provides effects similar to that of training combined with electrical accupuneture,and is more effective than simple training in treating dysphagia.

Objective To investigate the expression and significance of the endocrine gland-derived vascular endothelial growth factor (EG-VEGF) and vascular endothelial growth factor(VEGF) in adrenocortical lesions of primary aldosteronism. Methods The expressions of EG-VEGF, and VEGF were detected by immunohistochemistry and real-time fluorescence quantitative PCR in samples of 18 cases of adrenocortical adenoma, 6 adrenocortical hyperplasia, and 8 normal adrenal cortex. The correlation between the expressions of EG-VEGF, VEGF, and clinicopathological parameters was analyzed. Results The expression of EG-VEGF or VEGF in adrenocortical adenomas was higher than that in adrenocortical hyperplasia or normal adrenal cortex ( all P<0. 05 ), and the expression of EG-VEGF or VEGF between adrenocortical hyperplasia samples and normal adrenal cortex samples was indistinctive. There was no statistically significant correlation between EG-VEGF or VEGF expression and sex, age, blood pressure, serum potassium, plasma renin activity, except in case of serum aldosterone( P<0.05 ). A positive correlation between EG-VEGF and VEGF ( P<0. 01 ) was found. Conclusions EG-VEGF and VEGF may play a significant role in the formation and development of adrenocortical tumors in primary aldosteronism.

The expressions of Ki67 and FHIT were detected by immunohistochemical staining in 15 cases of adrenocortical carcinoma, 42 cases with adrenocortical adenoma,6 cases of adrenocortical hyperplasia, and 10 cases of normal adrenocortical tissue. The results showed that the highest expression of Ki67 and the lowest expression of FHIT were found in adrenocortical carcinoma. There were significant differences in the Ki67 and FHIT between adrenocortical adenoma and adrenocortical carcinoma ( both P < 0. 05 ). There existed negative correlation between the expressions of Ki67 and FHIT( r=-0. 712, P<0.05 ). Ki67 over-expression and loss of FHIT expression may be involved in the occurrence and development of adrenocortical carcinoma. It is suggested that combined detections of Ki67 and FHIT may have reference significance in the differentiation of adrenocortical adenoma from adrenocortical carcinoma.

Molecular imprinting technique (MIT) involves the synthesis of polymer in the presence of a template to produce complementary binding sites in terms of its size, shape, and functional group orientation. Such kind of polymer possesses specific recognition ability towards its template molecule. Despite the rapid development of MIT over the years, the majority of the template molecules that have been studied are small molecules, while molecular imprinting of proteins remains a significant yet challenging task due to their large size, structural flexibility and complex conformation. In this review, we summarize the research findings over the past five years, and discuss the characteristics of the technique, the most recent progress and the perspective in the field of molecular imprinting of proteins.
