Method Retrospectively, we analyzed the clinical characteristics of 756 cases who respectively received hysterectomy by total abdominohysterectomy (TAH,260 cases), modified abdominohysterectomy (MAH, 180 cases), transvaginal hysterectomy (TVH, 106 cases), or laparoscopic assisted vaginal hysterectomy (LAVH)(210 cases) and compared their effects and outcomes. Results The average operation time of TAH(98 ?23)minutes, MAH(67?18)minutes, TVH (63?19)minutes and LAVH(99?35)minutes. The average operation time of LAVH and TAH groups was significantly longer than that of TVH and MAH groups (P

Objective To investigate the relationship of serum and carcinoma levels of plasminogen activator inhibitor-1 (PAI-1)with clinical characteristics in patients with endometrial carcinoma.Methods Serum level of PAI-1 was determined by using enzyme-linked immunosorbent assay(ELISA) in patients with endometrial carcinoma (n =40),uterine prolapsed with normal endometrial tissues(n=40).The protein expression of PAI-1 in endometrial tissue was detected by using immunohistochemistry in patients with endometrial carcinoma and uterine prolapse patients.Results Serum level of PAI-1 was higher in patients with endometrial carcinoma than in uterine prolapse patients with normal endometrial tissues(19.43±7.12 μg/L vs.6.58±2.33 μg/L,P＜0.05).The rate of positive expression of PAI-1 was higher in endometrial carcinoma tissue than in uterine prolapse tissue[62.5 ％ (25/40) vs.7.5 ％ (3/40),P ＜ 0.01].Compared with early-stage endometrial carcinoma,advanced endometrial carcinoma had an increased rate of positive expression of PAI-1 (P ＜0.01).Compared with endometrioid adenocarcinoma,other pathological types of endometrial carcinoma had an increased rate of positive expression of PAI-1 (P ＜ 0.05).Poorly differentiated endometrial carcinoma versus highly differentiated endometrial carcinoma had an increased positive rate of PAI-1 (P ＜0.05).The rate of positive expression of PAI-1 was higher in endometrial carcinoma with myometrial invasion than without myometrial invasion(25/31 vs.0/9,P＜0.01).Conclusions The expression level of PAI-1 may be related to the invasion and metastasis of endometrial carcinoma.

Objective To investigate the efficacy and safety of modified anterior vaginal wall repair in the treatment of anterior vaginal prolapse and cystocele in elderly women.Methods We retrospectively analyzed the clinical value of modified anterior vaginal wall repair in 58 elderly women with stage Ⅱ-Ⅳ anterior vaginal prolapse and cystocele,which were evaluated by pelvic organ prolapse quantitation (POP-Q) system.The modified anterior vaginal wall repair was based on the paravaginal repair as an add-on to a reverse bridge repair and cross stitching of bilateral sutures stemmed from vaginal repair.According to the condition of each patient,other pelvic floor repair,perineal laceration repair,and paraurethral fascia reinforcement might be performed at the same time.The curative effectiveness was subjectively and objectively evaluated in the postoperative follow-up.Results A total of 58 operations were successfully finished.The follow-up time was 6-24 months with an average of (14±8) months.The subjective cure rate was 100％ and the rate of objective cure defined as the top of the vagina above the level of ischial spine was 100％ at 3 months follow-up (n=58).The subjective and objective cure rate was 100％ and 96.6％ (56/58) at 6 months follow-up (n=58),100％ and 94.1％ (32/34) at 12 months follow-up (n=34),91.7％ (11/12) and 91.7％ (11/12) at 24 months follow-up (n=12),respectively.Conclusions The modified anterior vaginal wall repair is safe and effective for anterior vaginal prolapse and cystocele in elderly women.

OBJECTIVETo investigate the relationship between miR-501-5p expression and the clinicopathological factors in patients with lung adenocarcinoma in Xuanwei area.

METHODSSurgical specimens of lung adenocarcinoma and paired adjacent tissues from 24 patients with lung adenocarcinoma from Xuanwei area were examined for miR-501-5p expression using microRNA microarray technique and qPCR. Chi-square test was used to analyze the association of miR-501-5P expression with the clinicopathological characteristics of the patients. Multiple regression analysis was performed to analyze the association of miR-501-5p expression with the patients' gender, age, tumor stage, and preoperative CEA level.

RESULTSMicroRNA microarray analysis and qPCR validation results revealed significantly upregulated expressions of miR-501-5p in patients with lung adenocarcinoma from Xuanwei area (Plt;0.01). The microarray data showed an up-regulation of miR-501-5p by 3.17 folds in lung adenocarcinoma tissue compared with the adjacent tissue (P=0.22376, FDR=0.071395). Chi-square test indicated that miR-501-5p expression level was associated with the patients' age (f=7.168, P=0.014), TNM stage (f=36.627, P<0.01), and preoperative serum CEA level (f=30.045, Plt;0.01), but not with the patients' gender (f=3.612, P=0.071). Multiple regression analysis revealed that miR-501-5p expression was positively correlated with the patients' age, TNM stage of the tumor, and serum CEA (Plt;0.05).

CONCLUSIONmiR-501-5p expression is up-regulated in lung adenocarcinoma with significant associations with the patients' age, TNM stages and serum CEA level in patients from Xuanwei area, suggesting its potential role in the tumorigenesis and progression of lung adenocarcinoma in Xuanwei area.
