Objective: To investigate the expression of vasculogenic mimicry (VM) in endometrial carcinoma tissues and its rela-tionship with the clinicopathologic features and prognosis of the disease. Methods: A total of 267 paraffin-embedded endometrial carci-noma specimens of patients with complete follow-up data were collected from the Shijiazhuang Bethune International Peace Hospital between January 2005 and June 2014. CD31-PAS dual staining was performed to identify the VM structure. Tissue samples were then divided into VM-positive and VM-negative groups. CD133 expression was detected by immunohistochemical streptavidin peroxidase method. Results: Among the 267 endometrial carcinoma patients, 65 cases (24.3%) were VM positive. VM formation was closely corre-lated with the International Federation of Gynecology and Obstetrics Staging (χ2=9.987, P=0.002), histodifferentiation grade (χ2=11.795, P=0.001), myometrial invasion depth (χ2=5.499, P=0.019), vascular cancer embolus (χ2=22.599, P<0.001), and lymph node me-tastasis (χ2=7.848, P=0.005). Kaplan-Meier survival curve analysis showed that survival time was significantly shorter in the VM-posi-tive group (median survival time was 51 months) than in the VM-negative group (median survival time was 100 months) (χ2=70.973, P<0.001). Moreover, CD133 expression was significantly higher in the VM-positive group [75.4% (49/65)] than in the VM-negative group [58.9% (119/202)] (χ2=5.720, P=0.017). Conclusion: VM is closely correlated with the pathogenesis, development, and malignancy of endometrial carcinoma. Furthermore, VM is one of the important indexes influencing the prognosis of this disease. Therefore, CD133-positive cells may contribute to VM formation.

Excessive medical treatment goes against the human rights of patients and therefore must be stopped.Main reasons include the impulse of existing medical benefit mechanism,the morality decline of medical staff,and patients' eagerness to shake off physical pain and psychological advocating for high-cost medical expenditure.This paper also comes up with relevant countermeasures including reversing the current healthcare mechanism,establishing an evaluation system for medical ethics of medical staff,and building up a monitoring mechanism for the development of clinical guidelines of evidence-based medicine.

The obese children are increasing at a surprisingly high annual rate of 9.1 percent in China.Meanwhile children are lack of health consciousness and self-protection,thus obese children are more vulnerable towards obesity.Since parents are responsible for their children's daily lives and behaviors,the health education of obesity should be started with those parents with obese children.This paper calls to carry out health education aimed at parents of obese children through multiple means such as community health services,taking advantage of public media and establishing specific clubs,in order to effectively control the increase of obese children.
