Objective To analyze the change of surgical route and range of hysterectomy in the past 10 years.Methods From January 2000 to December 2010,the clinical data of patients with hysterectomy were analyzed retrospectively,including clinical features,surgical path and scope of operation.Results There were 1980 patients.The predominant reason for hysterectomy was leiomyomas (52.88%,1047/1980),adenomyosis (17.78%,352/1980),cervical intraepithelial neoplasia (12.17%,241/1980).The age of the patients with hysterectomy for abdominal,transvaginal and laparoscopic was (46.54 ± 7.35),(58.73 ± 10.49),(44.10 ±5.12) years.In 2000-2005,the proportion of abdominal,transvaginal and laparoscopic proportion were 81.78% (615/752),8.64% (65/752) and 9.57% (72/752).In 2006-2010 were 64.50% (792/1228),6.51% (80/1228) and 28.99% (356/1228).In 2006-2010,the proportion of abdominal significantly decreased and laparoscopic significantly rised compared with those in 2000-2005,there were statistically significant differences (P < 0.01).In 2000-2005,unilateral and bilateral annex removal ratios were 15.43% (116/752),12.23% (92/752),in 2006-2010 were 8.63% (106/1228),7.49%(92/1228).Unilateral and bilateral annex removal ratios in 2006-2010 were significantly lower than those in 2000-2005,there were statistically significant differences (P < 0.01 or < 0.05).Conclusions Over the past 10 years,hysterectomy route and range changed with the percentage of laparoscopic increasing,and concomitant unilateral or bilateral annex removal decreased.

AIM: To investigate whether salidroside has influence on the activities of endothelial progenitor cells (EPCs) and its mechanism.METHODS:Mononuclear cells from normal human peripheral blood were cultured in fi-bronectin coated flasks in endothelial progenitor medium .After 7 d, EPCs were characterized as adherent cells with acLDL-DiI uptaking and lectin binding by direct fluorescent staining .The proliferation and migration of EPCs were analyzed by MTT assay and Transwell chamber assay , respectively.The EPCs adhesion assay was performed by re-plating the cells on fibronectin-coated dishes , and then adherent cells were counted .NO and Akt protein were also detected .RESULTS:Sali-droside promoted EPCs proliferative , migratory and adhesive capacities in a concentration dependent manner .Salidroside also increased NO secretion , and the level of phosphorylated Akt protein .However , the effects of salidroside on EPCs were inhibited by phosphoinositide 3-kinase inhibitor LY294002.CONCLUSION:Salidroside regulates the activity of EPCs by phosphoinositide 3-kinase/Akt signaling pathway .

Objective · To investigate the status of depression and anxiety in patients with recurrent spontaneous abortion (RSA) and the possible influence factors and to provide theoretical support for further psychological intervention. Methods · RSA patients and women with no history of RSA were invited to complete a questionnaire, including basic information, Self-Rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS). All data were analyzed by SPSS. Results · Of all 1064 cases included in this study, 725 were RSA cases, 217 cases with one spontaneous abortion and 122 in control group with no history of spontaneous abortion. Our results showed that both RSA patients and patients with one spontaneous abortion have significantly higher SDS and SAS scores than control group. Furthermore, non-pregnant RSA patients with lower education level, lower household income and 3-5 years of marriage have significantly higher levels of depression and anxiety. Patients with multiple miscarriages (≥4), history of induced abortion and no live birth, score significantly higher in SDS. Conclusion · Whether pregnant or not, RSA patients are much easier to become depressive and anxious, which may be associated with education level, household income, length of marriage, numbers of pregnancy losses and previous live birth. Women with one spontaneous abortion also show a significant higher tendency of depression and anxiety. These patients should be given proper psychological intervention if necessary.

To prevent the perforation of nasal septum due to button battery lodging in nose.
METHOD:
In 34 cases of nasal button battery, 28 were removed under general anesthesia and 6 under local anesthesia. The general treatment of nasal douching and local dressing were done after operation.
RESULT:
Only 1 case of perforation were found in 25 cases undertaken general treatment after operation, and perforation were found in all 9 cases with no general treatment.
CONCLUSION
Nasal douching and local dressing after battery removing can alleviate the mucosal erosion and decrease the sequels of nasal button battery.

Objective To analyze the mammographic features of invasive lobular carcinoma (ILC)compared to those of invasive ductal carcinoma (IDC).Methods Twenty cases with ILC and 95 cases with IDC were retrospectively evaluated by two breast radi-ologists according to the Breast Imaging Reporting and Data System (BI-RADS)lexicon.The mammographic findings were com-pared between ILC and IDC with the independent samples chi-square test or Fisher’s exact test,as appropriate.Results Mass was the most common finding in both ILCs and IDCs,but less frequent in ILCs (36.4% vs 63.9%,P =0.008).Mass in ILCs was more frequently lobular or irregular shape with spiculated margin.Architectural distortion and focal asymmetry were more frequent in ILCs than in IDCs,however,the differences were no significant.The frequency of calcifications was not significantly different between the two groups.The distributions of calcifications were more regional in ILCs,and more segmental or linear in IDCs (P =0.01).Conclu-sion ILCs are more usually shown as non-mass appearances on mammography.ILCs that appeared as mass are more frequently ir-regular in shape with spiculated margins.

Objective To explore a reasonable,accuracy and effectual proposition model for medical imaging examination.Methods Mean scores and their standard deviation and distribution as well as the difficulty,discrimination,reliability and validity of the test paper were analyzed for the 2005 grade 7-year program students by using SPSS 13.0 statistic software.Results The scores of the 67 copies of test paper displayed a normal distribution,with the mean score of 73.76 and standard deviation of 11.88.The difficulty,reliability and validity indexes of the test paper were 0.74,0.78 and 0.25 respectively.The difficulty,discrimination,reliability and validity indexes of subjective items were higher than those of objective items(0.76 vs.0.73,0.94 vs.0.90,0.71 vs.0.68,0.32 vs.0.22,respectively).Conclusions We should keep quite high proportion of subjective items and make detailed scoring standard in medical imaging examination.Furthermore,as a supplement,objectively items such as multiple choice questions can expand the scope of knowledge examined.
