Methods HUVEC were cultured and stimulated with sera, and the expression of ICAM 1 and P selectin by flow cytometry were measured. Results (1) The expressions of ICAM 1 of P selectin on the HUVEC surface after stimulation with sera from women with ICP were higher than those of without stimulation in normal pregnancy ( P

Objective To evaluate renal vascular damage (RVLs) and detect the expression of miR-145 in children with lupus nephritis (LN).Methods Clinical data of 41 cases of LN diagnosed by renal biopsy from the children with systemic lupus erythematosus (SLE) were collected. Glomerular damage score and RVLs were evaluated. The children were divided into groups according to RVLs score and pathological pattern. In situ hybridization was performed to detect the expression of miR-145 in kidney blood vessel. Differences in RVLs, miR-145 expression in the renal blood vessels and glomerular damage score were observed among the groups with different renal pathological pattern. Differences in clinical parameters, glomerular damage score and miR-145 expression in the renal blood vessels were investigated among groups with different RVLs. Results Among the groups with different pathological pattern, there was no difference in RVLs (P>?0.05) while signiifcant different were found in the expression of miR-145 and glomerular damage score (P??0.05) while a statistical different was found in the expression of miR-145 (P?

Objective To study the role of expressions of vascular endothelial growth factor C (VEGF-C), vascular endothelial growth factor receptor-3 (VEGFR-3) and lymphatic vessel hyaluronan receptor-1(LYVE-1) on the lymphangio-genesis and prognosis in gastric cancer. Methods The tissue microarray technology was used to detect the expressions of VEGF-C, VEGFR-3 and LYVE-1 in 125 gastric cancer specimens, 96 adjacent normal tissues and 20 benign gastric lesion samples. The lymphatic vessel density (LVD) marked by Podoplanin was detected as well. Results The positive rates of VEGF-C, VEGFR-3 and LYVE-1 in gastric cancer tissues were 62.4%, 56.0%and 58.4%, which were significantly higher than those in adjacent normal tissues (10.4%,12.5%and 9.4%) and benign gastric lesion tissues (20%, 30%and 25%, P<0.05). The LVD score was significantly higher in gastric intra-tumoral and peri-tumoral samples (2.98±0.81 and 4.22±1.09) than that in adjacent normal tissues or benign gastric lesion samples (1.82±0.63 or 0.89±0.45, P<0.01). The LVD score was significantly higher in peri-tumoral samples than that of intra-tumoral samples (P<0.01). There was a positive relationship between expression levels of VEGF-C,VEGFR-3 and LYVE-1 with LVD (P<0.05). The positive expressions of the three indexes were the risk factors of lymph node metastasis and distant metastasis (P<0.05). There was a significantly longer 5-year survival rate in patients with negative expression of the three indexes (P<0.05). Conclusion VEGF-C, VEGFR-3 and LYVE-1 proteins were positively highly expressed in gastric cancer tissues, which were risk factors affecting the progno-sis of gastric cancer. The expression levels of the three indexes can be used to predict the prognosis and lymphangiogenesis of gastric cancer.

Objective To explore the effect of separate management of income and expenditure (SMIE) on standard community healthcare services. Methods Health management records of 137 community health service ( CHS) institutions in Beijing during 2006 and 2009 were retrospectively analyzed. Paired t test was used to compare annual healthcare services at urban and rural areas before or after SMIE was adopted. Results The standard community healthcare services was reduced from 1 081 965. 53 to 971 793. 98 at urban areas and from 157 492. 23 to 149 305. 25 at rural areas (P >0. 05). Urban healthcare center-based standard services was decreased from 59. 94% to 52. 14% (P < 0. 05 ); while out-hospital services were increased from 13. 50% to 18. 88% (P<0. 05). In urban areas,standard services for women healthcare, chronic disease profiling, health education and information management were significantly increased (I <0. 05). However,Temporary observation and endemic disease prevention and treatment were the main job of rural healthcare. Conclusions SMIE in CHS institutions could accommodate to the need of health management, supporting policies should be further improved.
