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.

Purpose To explore the effect of ultrasonic section,patient position and other factors on Young's modulus and shear wave velocity measurement of the muscle,and to study the consistency between Young's modulus and shear wave velocity on reflection of muscle hardness.Materials and Methods Shear wave elastography was used to detect 10 healthy young men and 10 women.Longitudinal and transverse detection of the Young's modulus and shear wave velocity of gastrocnemius and soleus were performed in natural ankle joint position,maximum plantar flexion and maximum dorsiflexion position.Results ① Comparison of the elasticity measurement between gastrocnemius and soleus.There were significant differences in the Young's modulus in the maximum plantar flexion and Young's modulus and shear wave velocity in maximum dorsiflexion position in longitudinal detection (P＜0.05) that gastrocnemius measurements were higher than soleus measurements.There were significant differences in Young's modulus and the shear wave velocity (P＜0.05) in natural position and maximum dorsiflexion position that soleus measurements were higher than gastrocnemius measurements.② In the positions of the ankle joints,the differences between longitudinal detection values and transverse detection values of gastrocnemius or soleus were statistically significant (P＜0.01) and longitudinal detection values were higher than transverse detection values.③ Comparison of the elasticity measurement of gastrocnemius and soleus muscle among different positions of the ankle joints.The measurement in natural position and in the maximum plantar flexion were evidently higher than that in the maximum dorsiflexion position (P＜0.01) in longitudinal detection.The maximum dorsiflexion position showed higher elasticity measurement.Only elasticity measurement in natural position and the maximum plantar flexion of the soleus was statistically different from that in the maximum dorsiflexion position (P＜0.01) that it was higher in the maximum dorsiflexion position.Conclusion The ultrasound elasticity measurements of gastrocnemius and soleus are related with the ultrasonic longitudinal or transverse section and the relative ankle positions.Moreover,there are some differences in elasticity measurements between these two muscles.should be given to all of these in quantitative evaluation of muscle hardness using shear wave ultrasound elastography.

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.

?AlM: To investigate the expression of miR-181 in the lens tissue of cataract and the regulating mechanism of miR-181 on apoptosis of human lens epithelial cell.
?METHODS:Real time q-PCR was used to measure the expression of miR-181 in the anterior lens capsules of age - related cataract and human lens epithelial cell apoptosis model. miR- 181 mimic and inhibitor were transfected using Lipofectamine 2 000 to regulate the expression of miR-181, and then Real time q-PCR was used to verify transfection efficiency. Flow cytometry was used to detect the change of cell apoptosis rate.
? RESULTS: Compared with control group, the expression of miR-181 was significantly higher in both the anterior lens capsules of age-related cataract and human lens epithelial cell apoptosis model; the relative expression of miR-181 in lens epithelial cells transfected with miR-181 mimic was increased, whereas decreased in cells transfected with miR-181 inhibitor;the apoptosis rate of cells transfected with miR - 181 mimic was increased, while reduced in miR-181 inhibitor group. Each result was statistically significant (P<0. 01).
?CONCLUSlON:High expression of miR-181 is detected in anterior lens capsule of age-related cataract. miR-181 might play a certain role in the pathogenesis of cataract via promoting human lens epithelial cell apoptosis. miR-181 probably becomes a new approach for the nonoperative treatment of cataract, but the concrete mechanism still needs to be further studied.

Objective To measure serum surfactant protein (SP) A and D levels in patients with interstitial lung disease associated with rheumatoid arthritis (RA).Methods Serum SP-A and SP-D levels of RA,RA-ILD patients and healthy controls were assessed using a sensitive enzyme-linked immunosorbent assay (ELISA).The relationship between SP-A and SP-D and RA-ILD was analyzed.The serum SP-A and SP-Dpositive rate was calculated for the three groups.The correlation between SP-A and SP-D with RF,anti-CCP,antinuclear antibody,antikeratin antibody,anti-perinuclear factor,C-reactive protein,erythrocyte sedimentation rate,were analyzed.Mean value of groups were compared with variance analysis,Spearmam rank correlation test was used for correlation analysis.Results The levels of serum SP-A in RA-ILD patients and RA patients as well as in healthy controls were [ (51.2±9.2),(25.9±2.6),( 15A±0.3 ) μg/L] respectively.The level of serum SP-D of the three groups was [ ( 42.5 ±8.1 ),(20.8 ± 1.5 ),( 16.6±0.8 ) μg/L ] respectively.The levels of serum SP-A and SP-D in patients with RA complicated with ILD were higher than those simple RA patients and healthy controls (P＜0.05).The levels of serum SP-A and SP-D in patients with RA were not significantly higher than those in healthy controls (P＞0.05).The positive rate of serum SP-A and SP-D in RA-ILD patients were significantly higher than those in simple RA patients and healthy controls.The positive rate of serum SP-D of RA-ILD patients was higher than that of SP-A.The levels of serum SP-A and SP-D in patients with RA complicated with ILD were correlated positively with age,C-reactive protein.The level of serum SP-D was correlated positively with RF,anti-CCP,antikeratin antibody.There was no correlation between the level of serum SP-A and SP-D with RA-ILD and antinuclear antibody,antiperinuclear factor,erythrocyte sedimentation rate.Conclusion The levels of serum SP-A and SP-D are correlated with RA-ILD and may be useful markers for ILD in patients with RA.These two paramenters may be helpful to early diagnosis of RA-ILD.The Serum SP-D levels are more sensitive in predicting the development of RA-ILD than other parameters and can help in assessing the severity of lung damage.
