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.

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 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.

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.

Objective To explore the impact of morphological changes of mitral valve coaptation on ischemic mitral regurgitation (IMR),and observe coaptation image of mitral valve in systole in patients with IMR by using real-time three-dimensional transesophageal echocardiography (RT3D-TEE).Methods RT3D-TEE was performed on 112 patients with IMR and 38 patients without MR as the control.Patients with IMR were divided into group of mild IMR (n =46),group of moderate IMR (n =45) and group of severe IMR (n =21),according to the severity of mitral regurgitation.Mitral valve quantification (MVQ)software of Qlab 8.1 was used for image post-processing of RT3D-TEE.The coaptation parameters was measured,included length of anterior combination(LCA3dlf),length of posterior combination(LCP3dlf),area of anterior combination(A3DTANT) and area of posterior combination (A3DTPOST) at end-systole.Then,these coaptation parameters of mitral valve were compared statistically.Logistic regression assessing was applied for analyzing the results.Results Coaptation line of anterior and posterior leaflets was almost same in normal subjects.With increasing of mitral regurgitation,a tendency to prolong in LCA3dlf and LCP3dlf were observed in IMR (P <0.05).Compared to that in mild and moderate IMR groups,besides A3DTANT and A3DTPOST,LCA3dlf and LCP3dlf were also increased significantly in severe IMR group (P <0.05).LCP3dlf was an independent correlation factor of IMR by Logistic regression analysis.The sensitivity was 73.3% and the specificity was 94.7% when LCP3dlf≥32 mm was regarded as cut-off point,and the area under the ROC curve was 0.949 (0.900~0.999).Conclusions Abnormal coaptation of anterior and posterior leaflets of mitral valve might be one of main cause of IMR.Involution structure of mitral valve before surgery is helpful for surgeon to select an optical surgical procedure and evaluate effects of treatment in patients with IMR.
