In this paper , we summarize the theoretical models and research progress about program evaluation and practical situation of children ’ s health in Nujiang prefecture .We then develop a framework for comprehensively evaluating the intervention for children ’ s health based on program theory .This framework comprises the outside pro-gram environment , intervention action modules and change modules , and assessment techniques environment .The e-valuation mainly includes leading agencies , implementing agencies , coordinating agencies , coordination/implementa-tion personnel , intervention and service standards , the environment and atmosphere , target populations , interven-tions, determinants, outcome and effect .

The Theory of Change holds that the change in a project ’ s effectiveness can be derived from the changing process in the certain context .Only after analyzing changes caused by a project and the possible changing path or hypothesis can we determine the real cause of an effect .In 2012, the maternal, child and community health department of the former Ministry of Health began a comprehensive intervention project for children ’ s health in Nu-jiang Prefecture .The project was designed to explore modes and mechanisms for improving children ’ s health in the west, poverty and ethnic minority areas through cooperation at the national , provincial, and prefecture levels.Based on the Theory of Change , this article describes the logical framework of the comprehensive intervention project .In or-der to lay the foundation for improving the project design , ensuring the implementation of the project and conducting the follow-up monitoring and evaluation , we also expound the goals , implementation strategies , and intervention measures, project activities and output , implementation routes .

0.05). In the non-smoking group, the pulse pressures of patients with coronary heart disease were significantly higher than those of subjects with negative angiographic results. Among the three subgroups with different severity of coronary arterial lesion, the pulse pressure of 3-vessel diseases was higher than those of both 2-vessel and 1-vessel subgroup. The pulse pressure of subjects with negative angiographic results in smoking group was significantly higher than that in non-smoking group [(56.1?17.2) mm Hg vs (50.9?11.4) mm Hg,1 mm Hg=0.133 kPa P

AIM: To investigate the changes of intrarenal endothelin system in the course of congestive heart failure. METHODS: A canine congestive heart failure model induced by rapid right ventricular pacing was used in the present study. Twenty-one mongrel dogs divided randomly into 3 groups: control, congestive heart failure 2 weeks(CHF2) and congestive heart failure 4 weeks (CHF4). The severity of heart failure was evaluated by means of hemodynamic measurement. The concentration of plasma endothelin was detected via RIA, and the expression of endothelin was detected by RT-PCR. RESULTS: The concentration of plasma endothelin in both of CHF2 and CHF4 elevated significantly. In CHF2, the expression of endothelin receptor B(ETB) in renal medulla increased significantly. And in CHF4, the expression of preproendothelin, endothelin receptor A(ETA) and ETB increased both in renal cortex and medulla. Furthermore, in cortex, the expression of ETA increased more significantly than ETB, while in medulla, ETB expressed much more than ETA. CONCLUSION: The changes of renal endothelin system expression plays a role in the regulation of water and electrolyte balance during the progress of congestive heart failure.

AIM: To evaluate expression of the components of endothelin system in pulmonary tissue in a canine pacing-induced congestive heart failure model. METHODS: Twenty-one dogs were divided into 3 groups received 2 (pacing 2 group) or 4 weeks (pacing 4 group) rapid right ventricular pacing, respectively, whereas the other group consisted of 7 dogs received sham-operation as control group. Haemodynamic parameters were detected via left and right heart catheterization. Plasma endothelin-1 was determined by means of RIA. In addition, RT-PCR was used to quantify expression of mRNA of components of endothelin system using ?-actin as internal control. One-way ANOVA and linear regression analysis were used for statistical study. RESULTS:Plasma endothelin-1 increased significantly in heart failure animals. The ratio of preproET-1 to ? actin mRNA was significantly increased from 0.14?0.06 in control group to 0.35?0.08 in pacing 2 group and 0.53?0.08 in pacing 4 group ( P

Objective_To study the effect of Y-27632 on invasion and motility of SGC-7901 gastric carcinoma cells, and to find whether Y-27632 excerts the effect by attenuating SRF expression.Methods_SGC-7901 gastric carcinoma cells were divided into 3 groups:1)blank control group;2)Y-27632 group;3)siRNA-SRF-1107 group. Transfected siRNA-SRF or incubated by Y-27632 48 h.The effect of Y-27632 on proliferation suppressions of SGC-7901 gastric carcinoma cells was detected by CCK-8 assay.Cell invasion was examined by Transwell and wound healing test.The expression of SRF, ROCK1, E-cadherin, β-catenin, F-actin, MRTF-A and Cyclin D1 were detected by Western blot.Results_Y-27632 inhibited invasion (P<0.05)but had no effect on proliferation of SGC-7901 gastric carcinoma cells.Y-27632 reduced ROCK1, MRTF-A, F-actin, SRF protein expressions by 37.0%, 44.3%, 62.7%and 62.7%respectively, and E-cadherin protein expression was up-regulated by 2.64 folds(P<0.05).Conclusions_The inhibition of ROCK and up-regulation of E-cadherin by Y-27632 can inhibit the invasion and migration of SGC-7901 gastric carcinoma cells that is explained at least, in part, by attenuating SRF expression.

Objective To investigate the correlation among mammographic features、pathology and molecu-lar biology markers of breast infitrating ductal carcinoma(IDC) tissues.Methods The mammographic features of 93 cases with IDC confirmed by surgery and histopathology were analyzed retrospectively.The mastectomy specimens of the IDC were stained with immunohistochemistry,and the expression of ER、PR、C-erbB-2 were measured.The rela-tionship between the immunohistochemical pathologic results and mammographic features was analyzed.Results A-mong the 93 cases of IDC,ER positive expression was positively correlated with the spiculate margin of breast cancer (P<0.05);C-erbB-2 positive expression was positively correlated(P<0.05).Moreover,ER and PR positive expres-sion showed a significant inverse correlation with the calcifying of breast cancer(P>0.05);ER and PR positive ex-pression was positively correlated with the transfer of lymph(P<0.05);there existed correlation between the positive expression of C-erbB-2 and lymphatic metastasis and pathohistology grade(P<0.05).Conclusion There was a pos-itive correlation among IDC mammography、pathology and the abnormal value of ER、PR and C-erbB-2.The X-ray mammography could reflect the diagnosis value of ER、PR and C-erbB-2 roughly,and thadpractical value in determi-ning prognoses and endocrinotherapy.

OBJECTIVETo investigate changes over time in the shape and signal intensity of high intensity zone (HIZ) in the lumbar intervertebral discs on magnetic resonance images in patients with low back pain.

METHODSThe imaging data were collected from 27 patients with low back pain, who underwent lumbar magnetic resonance (MR) imaging examinations that identified HIZ lesions and received follow-up MR examinations at least 1.5 years later over the period from January 2009 to January 2017. The initial and follow-up MR T2WI images of the patients were read by two experienced radiologists to categorize the changes in the shape of the HIZ lesions into enlarged, unchanged, shrunk, and disappeared. The volume and signal/cerebrospinal fluid signal intensity (T2/CSF) ratio of the HIZ were measured on sagittal MR images using ImageJ software.

RESULTSOf the 43 HIZ lesions found in the initial examinations, 22 (51.2%) remained unchanged in the follow-up examinations, 10 (21.3%) were enlarged, 9 (20.9%) shrank, and 2 (23.3%) disappeared. The follow-up examinations revealed 4 new HIZ lesions in the intervertebral discs. The volumes of these lesions did not vary significantly in the follow-up examinations (=0.653), but the T2/CSF ratio was significantly higher in the follow-up than in the initial examinations (=0.043).

CONCLUSIONSAfter observation for an average of 3 years and 3 months, most of the HIZ lesions in the lumbar intervertebral discs of the patients with low back pain remained stable in shape, but their signal intensity on MR images increased.
