Objective To explore the effect of community comprehensive intervention on stroke-prevention-related knowledge, belief and behavior of hypertensive patients. Methods The community-based comprehensive interventions were done to 77 hypertensive patients, with the measures including archives establishment, hypertension-phased management, regular follow-up and multi-mode health education. The stroke-prevention-related knowledge, belief and behavior of them were assessed by the stroke-preventing knowledge questionnaire (SPKQ), champion′s health belief model scale (CHBMS) and (stroke-prevention behavior questionnaire,SPBQ) before and after the intervention. Results Their knowledge on daily-life and pre-stroke symptoms and part of their behaviors (health duty, physical exercises and stress management after the intervention were superior, as compared to the pre-intervention (P<0.05). There were no significant differences in other stroke-related knowledge and behaviors and health belief in comparison of the pre-and post-intervention (P>0.05). Conclusion The community-based intervention can improve parts of stroke prevention knowledge and health behavior among hypertensive patients. The intervention needs to be modified based on ecological models of health promotion and health belief model.

To study the link between BRAFV600E status and the expression of BIM gene in papillary thyroid carcinoma( PTC) tissues and to analyze the association of these factors with clinicopathological characteristics. BRAFV600E status was determined by MASA-PCR, and qPCR was applied to detect the expression of BIM gene. Finally, the associations of these factors with clinicopathological characteristics were analysed. The rate of mutant BRAFV600E in PTC was 54. 1% , and the expression of BIM gene was lowered in BRAFV600E positive PTC tissues. Additionally, there was significant association( P < 0. 05) between BRAFV600E positiveness and raised TNM Staging (Ⅲ/ Ⅳ), and lowered BIM expression was significantly associated (P<0. 05) with the tumor size and raised TNM Staging(Ⅲ/ Ⅳ). These findings may help us to know more about the mechanism of PTC and to develop new diagnostic biomarkers or prognostic indicators of PTC.

Objective To compare the clinical and pathological features of Chinese young breast cancer(age ≤ 35)with elder patients(> 35)using Meta analysis .Methods Published studies concerning clinical and pathological features of young breast cancer in China were searched systemically and assessed .Stata12 .0 software was used for data analyzing and calculating OR and its 95%CI .Results Totally 31 studies were selected for Meta analysis ,and most of them were classified as 6 - 7 scores ,which showed the quality of articles was high .The risk factors of breast cancer and its pooled odds ratio values with statistical significance were as fol‐lows 6 .42(95% CI :4 .22 - 9 .79) ,0 .61(95% CI :0 .50 - 0 .74)when clinical staging of 0 - Ⅱ phase or Ⅰ - Ⅱ phase ,2 .25(95% CI :1 .69 - 2 .99)when histological type of Invasive carcinoma ,1 .73(95% CI :1 .23 - 2 .43)when histological grade of III grade ,1 .80 (95% CI :1 .23 - 2 .43)when positive of lymph node metastasis .Conclusion Compared with elder breast cancer ,the clinical and pathological characteristics of young breast cancer were mainly for the high misdiagnosis rate ,the late clinical stage ,the high pro‐portion invasive carcinoma ,the poor histological differentiation and the lymph node metastasising easily ,the hint of young breast cancer screening and treatment may be different principles and measures should be adopted .

ObjectiveTo establish a new biomechanical test for evaluating biomechanical properties of femoral metaphysis in ovariectomized rats.MethodsTwenty-five-month-old female Sprague-Dawley rats were randomly divided into ovariectomized (OVX) group and the sham-operated (Sham) group (n=10).Twelve weeks after operation,femur BMD and histomorphometry of distal femur were detected.Furthermore,femur biomechanical parameters were determined by diaphysis three-point bending test and a new designed metaphysis bending test.The relationships between the biomechanical parameters and BMD or bone histomorphometry were assessed with Pearson correlations.ResultsThe femur BMD,bone histomorphometrical indexes(％Th.Ar,Tb.N,Tb.Th),and biomechanical parameters(maximum load,yield load and stiffness) of OVX group significantly decreased compared with Sham group.In metaphysis bending test,the mean difference of the maximum load(Fmax),yield load(Fy) between group OVX and Sham were significant higher than that in diaphysis three-point bending test.Positive correlations between biomechanical parameters and femur BMD or bone histomorphometry indexes were observed in both the diaphysis bending and metaphysis bending test.The biomechanical parameters in the metaphysis bending test showed stronger correlations with BMD and bone.ConclusionFemur metaphysis bending test could be used to evaluate the biomechanical properties of osteoporosis.When compared with diaphysis bending test,femur metaphysis bending test is more sensitive in evaluating the change of biomechanical properties of femur in osteoporotic rats.
