Healthy rural reconstruction is a widely explored intervention implemented by China Rural Health Devel-opment Project with the support of the World Bank and UK Department for International Development. By using initial pro-ject baseline data survey, mid-term evaluation and supervision, terminal evaluation of acquired qualitative and quantitative data,this paper analyzes the intervention policy design and initial effects of China's healthy rural reconstruction. With transforming the living environment in rural areas as the starting point, the project has relatively achieved good results, by using different policy measures such as improving the environment, creating a social environment conducive to villagers' health, expanding and providing high-quality health services, foster healthy behaviors and lifestyles, etc. The main results include the expansion of the project to cover 745 administrative villages, the environment of healthy villa-ges is much better than other neighboring villages, villagers' health knowledge has been greatly increased, lifestyle be-haviors of villagers have improved, the attitudes and participation rate of residents in cultural and sports activities have improved, etc. This paper suggests implementing the healthy rural reconstruction nationwide. It is very important to in-tegrate the concept of healthy village throughout the connotation of all kinds of new rural reconstruction, so the concept of health is deeply rooted in rural areas and imperceptibly change people's living behaviors and habits.

Objective To explore the clinical features of type 2 diabetic patients with hypertension , and to analyze the influencing factors of glycemic control. Methods Using stratified cluster random sampling method, 5 communities were selected from urban areas of Huai'an in 2014. Type 2 diabetic patients managed by the communities were surveyed with questionnaire, physical and biochemical examinations. The related information and clinical features were compared between diabetic patients with and without hypertension. Logistic regression analysis was used to analyze the influencing factors of glycemic control. Results The number of well-controlled diabetic patients (HbA1c<7.0%) with and without hypertension (HbA1c<7.0%) were 419 (39.3%) and 480 (52.1%), respectively. Mean values of body mass index (BMI), diabetic duration and serum creatinine in diabetic patients with hypertension were significantly higher than those in diabetic patients without hypertension (P<0.05). The proportions of macrovascular complications and dyslipidemia in diabetic patients with hypertension were significantly higher than diabetic patients without hypertension (P<0.05). Multiple logistic regression analysis showed that high degree of education, high annual family income and high frequency of glucose monitoring were beneficial factors for glycemic control in diabetic patients with hypertension. Older age, hypertension, higher waist to hip ratio (WHR), the elevated triglyceride and serum creatinine were harmful factors for glycemic control. Conclusions The situation of glycemic control in diabetic patients with hypertension in urban areas of Huai'an is not optimistic. Therefore, community managements of risk factors such as central obesity and increased triglyceride in elder diabetic patients should be strengthened.

Objective To investigate MRI manifestations of lumbar and proximal femoral bone marrow changes before and after recombinant human granulocyte colony stimulating factor (rhG-CSF) was subcutaneous injected for healthy adults.Methods Twenty healthy blood stem cell donors without hematologic disease were enrolled in this study. All of them underwent lumbar sagittal and proximal femur coronal MRI examination with spin echo T1 WI and fat-suppressed T2WI.The first examination were performed before subcutaneous injection of rhG-CSF for comparison. In 4-7 days and 30-60 days after injection, the other two examinations were performed. The signal changes of lumbar and proximal femoral bone marrow were investigated by reading pictures and calculating the contrasted noise ratio (CNR).ResultsBefore rhG-CSF injection, all patients presented normal signal intensity of hone marrow. In 4-7 days after injection, all the 20 cases presented homogeneous signal decrease in lumbar vertebral bodys on T1 WI, accompanied by reduced fatty signal. In proximal femur, patchy or stripped hypointensity areas were found in intertrochanteric and subtrochanteric areas on T1 WI. On fat-suppressed T2 WI images, the signal of lumbar and proximal femoral bone marrow changed to equal or slightly-high signal intensity. In all cases,abnormal signal areas presented in lumbar and proximal femoral bone marrow occurred simultaneously in the same case.In the 10 cases received the third MRI during 30-60 days after rhG-CSF injection, signal intensity of lumbar bone marrow turned to normal in all sequence, but abnormal signal intensity areas were still existed and extended to distal part in femoral bone marrow, which appeared as symmetric stripped or patchy equal or slightly-low signal intensity on T1 WI and equal or slightly-high signal intensity on T2 WI. The CNR of lumbar bone marrow to subcutaneous fat before rhG-CSF injection, in 4-7 days and 30-60 days after rhG-CSF injection were 114. 11 ± 15. 11,71.04 ± 12. 25 and 91.64 ± 1 I. 68, respectively. Significant difference was found between before rhG-CSF injection and 4-7 days after injection ( P < 0. 05 ) , but no significant difference between the others( P > 0. 05 ). Conclusion After injection of rhG-CSF, the short-term changes of hematopoietic cells and fat content in bone marrow can be displayed on MRI, which provided non-invasive information for bone marrow transplantation.

Objective To investigate the mechanism of therapeutic action of dexamethasone on asthmatic mice by detecting the levels of IL-25 and IFN-γ in bronchoalveolar lavage fluid (BALF). Methods Balb/c mice with SPF grade were randomly divided into normal control group, asthma group and dexamethasone group. Asthma group and dexamethasone group were sensitized and challenged with ovalbumin ( OVA) . Dexamethasone group was intraperitoneally injected with dexamethasone one hour before challenging. The mice were executed 24 hours after the last challenge, and the HE stained pathological sections of the right lung were made. Pathological sections of lung were observed. BALF in the left lung was also collected. The total white blood cell count and absolute eosinophile ( EOS) count were observed, and the percentage of EOS was calculated. The levels of IL-25 and IFN-γwere measured with ELISA, and correlation analyses were made. Results The counts of total white blood cell and EOS, and the percentage of EOS were significantly higher in the asthma group than in the normal control group and dexamethasone group (P<0. 05). No differences were found between the normal control group and dexamethasone group. The IL-25 level was higher in the asthma group than in the normal control group and dexamethasone group (P<0. 05), and its level in the dexamethasone group was also higher than that in the normal control group. The IFN-γlevel was lower in the asthma group than in the normal control group and dexamethasone group (P<0. 05), while there was no significant difference between the normal control group and dexamethasone group. IL-25 was negatively correlated with IFN-γin each group. Conclusion Part of the mechanisms of dexamethasone acting on asthma are related to its inhibition on the pulmonary inflammation and promotion on the expression of IFN-γ, and possible inhibition of IL-25 expression.
