RESUMEN
Objective To identify and verify the different genes expression pattern between human endometrial endothelial cells (HEEC) isolated from endometrial cancer and normal endometrium.Methods Endothelial cells were isolated from 5 patients with endometrial cancer (endometrial cancer group 1) and 5 patients with normal endometria tissue (control group 1) admitted from June to November 2007 in Shandong Cancer Hospital.Global expression patterns of endothelial cells were examined using oligonucleotide microarrays.Tissues from 36 patients with endometrial cancer(endometrial cancer group 2) and 10 normal endometrial tissues (control group 2) admitted from January 2007 to April 2008 were selected to verify the expression of different genes,in which up-regulated genes including ESM1,MMP-10,SPP1 and HMGB1 were tested by quantitative real-time PCR and immunohistochemistry.Results Microarray analyses revealed 317 genes that exhibited ＞ 2-fold or ＜ 0.5 differences were identified (including 191 genes up-regulated and 126 down-regulated).Pathway analysis showed that these genes involved cell cycle,cell adhesion molecules,and extracellular matrix-receptor interaction were obviously predominant.Of them,97 up-regulated genes and 44 down-regulated genes were related to angiogenesis.The mRNA expression of ESM1,MMP-10,SPP1 and HMGB1 in endometrial cancer group 2 were 0.898、3.890、1.433 and 1.881,respectively.Positive expression of SPP1,MMP-10,ESM1 and HMGB1 was observed in endometrial cancer group 2.However,the SPP1,ESM1 and HMGB1 was negative expressed in control group 2.Conclusion It shows that there are the different angiogenesis related genes between endometrial cancer and normal endothelium,which will provide insights into the anti-angiogenesis therapy for endometrial cancers.
RESUMEN
Objective To observe and cpmpare the efficacy and complications of hyperfractional integrated intraeavitary brachtherapy in middle-advanced squamous-cell carcinoma with the traditionsl brachytherapy.Methods In the observed group,328 patients with cervical cancer received hypeffractional integrated intracavitary after loading therapy between Jan 2004 and Jan 2005 were selected.The dose of point A was 2.5 Gy-3.0 Gy/fraction,2 fractions per week,and the total dose of reference point A was 49.8 Gy in stage Ⅱ b,52.6 Gy in stage in Ⅲb.In the control group,331 cases treated with traditional aflerloading brachytherapy between Jan 2002 and Dec 2003 were selected.The dose of point A was 5.0～7.0 Gy/fraction,1 fraction per week,and the total dose of point A was 50.1 Gy in stage Ⅱb,53.5 Gy in stage Ⅲb.In vitro irradiation began at the same time with the intracavitary brachytherapy.The whole pelvic was irradiated with 15 MV X-rays.Results In the observed group,the recent control rate of stage Ⅱb was 97.2%(104/107),94.1%(208/221)for stage Ⅲb.The 3-year survival rate was 80.5%(264/328).and the 5-year survival rate was 68.6%(225/328).The complication rate was 5.2%(17/328)for cystitis, 14.6%(48/328) for proctitis.Out of 331 cases in control group,the recent control rate of stage Ⅱb was 95.4%(103/108),92.8%(207/223)for stage Ⅲb.The 3-year survival rate was 75.2%(249/331),the 5-vear survival rate was 62.5%(207/331).The complication rate was 13.3%(44/331)for cystitis,and 32.3%(107/331)for proctitis.Conclusions Compared with combination of traditional brachytherapy and external radiotherapy,combination of hyperfraetional integrated brachtherapy therapy and external radiotherapy has no significant improvement for recent control rate and long-term survival rate,but could reduce the complication rates of cystitis and proctitis.
RESUMEN
Objective To study the clinical value of operation in advanced endometrial carcinoma.Methods A retrospective study was carried out in 78 patients with advanced endometrial carcinoma received operation in our hospital from Jan.1,1997 to Dec.31,2007.The basic operation procedures were included total hysterectomy,adnexectomy,omentectomy,appendectomy and resection of metastatic lesions located in abdomino-pelvic cavity.The criteria of satisfied operation Was considered that the sizes of residual leision was smaller than or equal to 2 cm,which Was used to evaluate the effect of operation.The prognostic factors were also analyzed.Results Among the 78 cases,the rate of ideal cytoreductive surgery was 83%(65/78),included 23 cases of no residual leisions,42 cases of residual leisions size smaller than or equal to 2 cm,while 13 cases of residual leisions size larger than 2 cm.The Survival rate of 1-year,3-year and 5-year were 91%(61/67),55%(28/51)and 28%(10/36),respectively.The results by single factor analysis shown that the survival rate were correlated with prognostic factors included extent of disease,ascites,size of residual lesions,circles of chemotherapy.Conclusion It is important value for advanced endometrial carcinoma to ideal cytoredutive surgery followed by combined chemotherapy,while radiotherapy no further therapeutic effects.
RESUMEN
Objective To evaluate the guiding effect of CT software to reduce the postoperative syndrome and surgery risk in patients with sinus disease performed the functional endoscopic sinus surgery (FESS). Methods Fifty patients of accessory sinus disease were scanned by spinal CT, and then three dimensions reconstruction made in workstation. Under center of ethmoid sinus ,the five groups of anatomy data measured were obtained , used to guide surgery and contrasted with result of no used to guide surgery in 68 patients in FESS. The data were performed the statistical management and compared with results of FESS. Results Under guided by five groups of anatomy data measured ,the postoperative syndrome was reduced by 16.0 percent; the curative effect went up by 15.0 percent; the pay for hospital was reduced 31.0 percent and the recurrence rate was reduced 8.6 percent. Conclusion Used the technic in FESS, the surgery risk, the recurrence rate and pay for hospital are reduced, but the curative effect go up. The technic is much adapt to be used in village and towns hospital where there aren′t navigation equipment.
RESUMEN
Objective To evaluate the clinical value of using three-dimensional reconstruction and incising software in facial fracture. Methods Twenty-nine patients of facial fracture were examined with spiral CT first and then the images were taken with three-dimensional reconstruction and incising software on work-station. 2D images, 3D images and incising images were evaluated. Results BZ 3D images were superior to 2D images in demonstrating the space relationship of facial fractures, such as the fracture location, range, fragments displacement. However 2D images were better in illustrating deep structure; The 3D images could illustrate deep structure as well as 2D images when combined with incising software. Conclusion 3D images can provide information of space relationship in assessing facial fracture. The range can be extended combining with the incising software, and do better for illustrating deep struction.
