Objective:To examine the utilization and cost of outpatient care and their influencing fac-tors among middle and aged peasant-workers in China. Methods:The data of China Health and Retire-ment Longitudinal Study ( CHARLS) collected in 2011-2012 were used and the data on peasant-workers aged 45 years and older were analyzed with Two-part Model. Results: The four-week outpatient rate of middle and aged peasant-workers was 13. 7% (407/2 974). The determinants of the rate included gen-der, marital status, economic level, household size, the place of insurance enrollment, self-assessed health and having or having no chronic diseases. The average outpatient cost was (400. 3 ± 56. 7) yuan (RMB) and the median was 138. 0 yuan. Multivariate analyses showed that outpatient costs were higher for those males who lived in Eastern China and worked at the same place with insurance enrollment, with fair to bad self-assessed health and chronic diseases. Conclusion:Allowing higher flexibility for migrants to transfer the new rural cooperative medical system ( NCMS ) between rural and urban areas and thus making reimbursement for medical services provided by undesignated providers received immediately could increase the use of outpatient services.

Objective To evaluate the relationship between recurrence of cryptogenic ischemic cerebrovascular disease (CICVD) and patent foramen ovale (PFO),as well as to access the clinical significance of PFO in ischemic cerebrovascular disease.Methods Consecutive patients with CICVD aged 15 to 70 years who were hospitalized in Department of Neurology,Xuanwu Hospital Capital Medical University from January 2008 to March 2011 were prospectively investigated.Identified by transesophageal echocardiography,patients were divided into two groups with respect to outcome:PFO group and non-PFO group.The recurrence of cerebral ischemic events was compared between the two groups after neurological follow-up.Results A total of 91 patients were recruited,including 57 patients with PFO and 34 patients without PFO.The follow-up period of two groups was 695 (506,1142) d.The recurrence rate at 15 months in patients with PFO (24.5％ (12/49)) was higher than those without PFO (6.9％ (2/29),x2 =4.391,P =0.036).Cum hazard curve indicated that recurrence risk of cerebral ischemic events in patients with CICVD in PFO group was higher than that of patients in non-PFO group during the follow-up period (P =0.044).Cox model used for multivariate survival analysis indicated that PFO was a risk factor for cerebral ischemic event recurrence among patients with CICVD (OR =4.159,95％ CI 1.178-14.689,P =0.027).Conclusions PFO is associated with increased recurrence risk of cerebral ischemia in CICVD patients.In addition,PFO may be a significant factor for ischemic cerebrovascular disease.

AIM: To investigate the effect of hypoxia on the expression of MMP-2 and TIMP-1 in pulmonary artery fibroblasts. METHODS: MMP-2 activity was measured by using gelatin zymography. TIMP-1 protein level was determined by immunocytochemistry and Western blotting. mRNA expression was determined by reverse transcriptase-polymerase chain reaction (RT-PCR). RESULTS: The production of MMP-2 mRNA and protein was down-regulated in pulmonary artery fibroblasts exposed to hypoxia for 24 h. Gelatin zymography also demonstrated that lower level of MMP-2 activity was induced after hypoxia. Meanwhile, hypoxia induced the up-regulation of TIMP-1 mRNA and protein in pulmonary artery fibroblasts. CONCLUSION: Hypoxia induces unbalance of MMP-2/TIMP-1 in pulmonary artery fibroblasts, which may contribute to the mechanism of hypoxic pulmonary vascular remodeling.

The up-regulation mechanism of membrane type I matrix metalloproteinase (MT1-MMP) in macrophages stimulated by silica in vitro and the contribution of early growth response 1 (Egr-1) transcription factor in the gene expression pathway were investigated. Macrophages stimulated by silica were treated with Egr-1 antibody or Egr-1 decoy oligodeoxynucleotides (ODN). The levels of MT1-MMP proteins were determined by Western blot and the expression of MT1-MMP mRNAs was detected by RT-PCR. The results showed as compared with control macrophages, silica-stimulated group showed up-regulated gene expression of MT1-MMP via Egr-1 (P<0.01). Compared with silica-stimulated macrophages untreated with antibody, the cells treated with 5 microg/mL Egr-1 antibody were associated with reduced expression of MT1-MMP protein (P<0.01) and mRNA (P<0.01). Compared with silica-stimulated untransfected group, the Egr-1 "decoy" ODN group was associated with reduction in the expression of MT1-MMP protein and mRNA (P<0.01). It was concluded gene expression of MT1-MMP which may play a critical role in silicosis was up-regulated by silica in macrophages. Egr-1 participated in the expression of MT1-MMP and positively regulated the expression. Both Egr-1 antibody and Egr-1 decoy ODN suppressed the expression of MT1-MMP through the Egr-1 pathway and may become a potential therapeutic tool in the management of silicosis in the future.

ObjectiveTo investigate the related factors of ischemic cerebrovascular diseases in patients with patent foramen ovale (PFO). Methods42 patients with PFO，aged ≤55 years old, with cerebral infarction or transient ischemic attack and treated with aspirin were involved. All patients were examined with transesophageal echocardiography. 6 cases relapsed and 36 cases did not. The size of PFO, serum fibrinogen level, and combination of atrial septal aneurysm (ASA) were compared. ResultsThey were followed up for (512.51±127.38) d. The serum fibrinogen level was (3.33±1.11) g/L in no relapse group, and was (4.40±1.49) g/L in relapse group （P=0.032）. There was not significant difference in the size of PFO (P=0.618) and combination ASA (P=0.554) between these groups. Logistic regression showed that patients with ischemic cerebrovascular diseases history involved in relapse (OR=46.913,95%CI:2.371～928.254), but the serum fibrinogen level did not （OR=2.656,95%CI:0.977～7.219）. ConclusionThe PFO patients with history of ischemic cerebrovascular diseases incline to relapse. It is not sure the influence of the serum fibrinogen level on it.

0.05).Conclusion DTI can noninvasive detect the potential disorder of corpus eallosum in vivo,thus providing useful information to differentiate the cerebral ischemia disease from multiple sclerosis.

Objective To analyze the risk factors for patients with cryptogenic ischemic cerebrovascular disease (CICVD) and patent foramen ovale (PFO), as well as to evaluate the relationship between common risk factors and PFO in cerebral ischemia. Methods Consecutive patients with CICVD aged 15 to 70 years who referred to Department of Neurology, Xuanwu Hospital, Capital Medical University from January 2008 to July 2011 were investigated. Identified by transesophageal echocardiography, they were divided into PFO group and non-PFO group with respect to outcome. The common risk factors of cerebral ischemic between 2 groups were compared. The relationship between these risk factors and PFO was analyzed. Results A total of 102 patients were investigated, including 61 patients (59.80%) with PFO and 41 patients (40.20%) without PFO. Positive family history of ischemic cerebrovascular disease proportion in PFO group (31.1%)was higher than that in non-PFO group (9.8%) (P=0.011). There was no significant difference in other observed indicators (P>0.05). Positive family history of ischemic cerebrovascular disease correlated with PFO among CICVD patients (r=0.251, P=0.011). Conclusion PFO was not only more common in CICVD patients, but also correlated with positive family history of ischemic cerebrovascular disease.
