Objective To analyze the difference of irradiation dose and volume of organs at risk (OAR) particularly in small intestine between supine position and prone position on intensity-roodulated radiotherapy(IMRT) for cervical cancer. Methods 11 patients with Ⅱ_B-Ⅲ_B cervical cancer were scanned with supine position and prone position by CT.The CT images were transported to TPS,then target volumes were delineated and the IMRT plans were designed respectively.The prescribed dose was 95%PTV receiving 45 Gy in 23 fractions of 2 Gy.The exposure volumes of the OAR at different position and different dose levels in the dose volume histograms (DVH) were compared and analyzed.Results When tlle dose di8tributions met to the clinic request,the exposure volumes of small intestine at prone position were redueed than that at supine position in dose range 46-30 Gy(P<0.05),but this phenomenon Was not distinct in low dose range(< 20 Gy)(P>0.05).The exposure volumes of bladder, rectum, femur head and spine cord were no obviously differences at dissimilar position. Conclusion IMRT of cervical cancer should adopt prone position.because their small intestine will be protected better.

Objective To explore the reasons and the best treatment options of facial mass complicated after exogenous growth factor injections.Methods 17 cases of postoperative complications caused by exogenous growth factor injections were retrospectively analyzed.15 patients with chin masses received mass resection and repairment with submental fat and fascial flap.Facial masses of the other 2 patients were located in cheek.Simple cheek mass resection was usually useful.All the patients had scar treatment.The postoperative satisfactory survey was investigated after 6 months.Results The incisions of 17 patients were healed well.An analysis through color Doppler ultrasound examination showed no residual or recurrent mass within half a year follow-up.One of the 17 patients had facial asymmetry and needed further treatment.Others were satisfied with the facial appearance of treatment.Conclusions The masses resulted from injection of exogenous growth factor should be cut off timely and reasonable reconstruction through fat and fascial flap and scar treatment are helpful to restore the original appearance of patients.

Two isolation methods for sorting of endothelial progenitor cells (EPCs): from peripheral blood mononuclear cells (PBMCs) and CD133(+) enriched cells were compared, by defining the cell morphology, phenotype, reproductive activities and function in vitro, to provide a reference for clinical application of EPCs. PBMCs from healthy subjects were used either directly for cell culture or for CD133(+) sorting. The two groups of cells were cultured in complete medium 199 (M199) for 7 to 14 days and the phenotypes of EPCs were analyzed by FACS. The proliferation of differentiated EPCs was studied by MTT assay, and the VEGF concentration was measured using an ELISA kit. ECM gel experiment and migration assay were performed in vivo. The results showed that PBMCs produced more colony-forming units (CFU) than CD133(+) enriched cells from the same volume of blood (P<0.01). From day 7 to 14, the two groups showed decreased expression of hematopoietic stem cell markers and increased level of endothelial markers, but CD144(+) cells in CD133(+) group were less than in PBMCs group (P<0.01). PBMCs group secreted more VEGF than CD133(+) group on the day 7 (P<0.01). As compared with CD133(+) group, PBMCs group had more potent potential of proliferation and vascularization in vitro. It was concluded that CD133(+) sorted cells showed a lower capacity of differentiation, secretion, proliferation and vascularization in vitro, suggesting that CD133-negative cells may be a preferential way to get EPCs for clinical therapy.

AIM: To compare the methods of two currently employed isolation methods for endothelial progenitor cells (EPCs): from total peripheral blood mononuclear cells (PBMCs) and from enriched CD133~+ cells, by defining the cell morphology, phenotype, reproductive activities and function in vitro, providing a reference for clinic application. METHODS: PBMCs from the healthy subjects were used for CD133~+ sorting or not. The two groups of isolated cells were suspended in complete medium M199 for 7 d to 14 d. EPCs phenotype were characterized by FACS. The proliferation of differentiated EPCs was studied by MTT assay, and VEGF concentration was measured using an ELISA kit. Matrigel experiment and migration assay were imitated vascularization in vivo. RESULTS: PBMCs produced more colony-forming units (CFU) than CD133~+ cells from the same volume of blood (P<0.01). From 7 d to 14 d, the two groups show decreased expression of hematopoietic stem cell markers and increased level of endothelial markers, but CD144~+ cells in CD133~+ group were lower than those in PBMCs groups (P<0.01). Cells in PBMCs group secreted more VEGF than that in CD133~+ group on 7 d (P<0.01). Compared to CD133~+ group, PBMCs group showed more potential of proliferation and vascularization in vitro. CONCLUSION: CD133~+ sorted cells show a lower capacity of differentiation, secretion, proliferation and vascularization in vitro, which is unable to differentiate to mature endothelial cells, indicating that it's not a preferential way to obtain EPCs for clinic therapy.

Objective To analyze and evaluate the impact of adolescents' sexual and reproductive health education on students' sexual knowledge,attitude and behavior.Methods A short-term intervention was conducted among high school students in two schools in Xixiang county,Shaanxi Province.The intervention was carried out in the forms of manual,video,discussion,consultation,and so on .The contents of intervention consisted of the knowledge about adolescent physiology,care,conception,STD/HIV, and so on. Results The results showed that students' knowledge increased significantly(11.92±4.61 before intervention vs 19.81±4.8 after intervention,P=0.000).The sexual attitude and behavior changed insignificantly,especially the change of behavior.Conclusion The intervention is significantly effective in increasing knowledge,but less effective in the change of attitude and almost ineffective in the behavior change.

Retrospectively from February, 2006 to June, 2009 the clinical characteristics of 14 misdiagnosed cases of insulinoma in the First Affiliated Hospital of Zhengzhou University were analysed. The rate of misdiagnosis was 38% ( 14/37). The rate of IRI/G≤0. 3 was 33%. Insulinoma has often been misdiagnosised when IRI/G≤0. 3. Hence a diagnosis of insulinoma can not be excluded with this IRI/G rate.
