Objective To find the source of CA 125 in serum and the values of the expression of CA125 in serum, ascites and tissue in patients with epithelial ovarian cancer. Methods Detected the expression of CA125 in the primary lesions of epithelial ovarian cancer and the metastasis in abdominopelvic cavity (peritoneal and omental metastatic lesions) by S-P immunohistochemical methods. Compared the expression of CA 125 in tuberculose focus and acute inflammation focus in abdominopelvic cavity and detected CA125 in serum and ascites by ELISA. Results The levels of CA125 in serum of the patients with epithelial ovarian cancer [(523.66±158.02)kU/L],benign epithelial ovarian tumor [(138.11±26.52)kU/L] and tuberculosis of abdominopelvie cavity [(486.56±147.10)kU/L] were higher than that with the normal ovary [(17.48±3.37)kU/L], and there were significant differences (P<0.05).The levels of CA125 in serum of the patients with epithelial ovarian cancer and tuberculosis of abdominopelvic cavity were significantly higher than that with benign epithelial ovarian tumor, and there were significant differenees (P<0.01). The levels of CA125 in ascites of the patients with epithelial ovarian cancer [(996.85±337.87)kU/L] and tuberculosis of abdominopelvic cavity [(596.78±197.10)kU/L] were higher than that with benign epithelial ovarian tumor [(179.48±63.08)kU/L] and normal ovary [(177.70±51.72)kU/L], and there were significant differences (P<0.01).The level of CA125 in ascites of the patients with epithelial ovarian cancer was higher than that with tuberculosis of abdominopelvic cavity, and there was significant difference (P<0.01). By correlation analysis, the relationship of the level of CA 125 in serum and in ascites of the patients with epithelial ovarian cancer was positive correlation(r=0.687). Conclusion Besides the original and metastatie lesions (greater omenta and peritoneum) of epithelial ovarian cancer can express CA 125, the second Maller canal, for example the peritoneum mesothelial cell can be stimulated to express CA125 by ascites, which results in the increase of CA125 in serum.

Objective To evaluate if the flexible ureteroscopy could treat stones located in lower calyx with the infundibulopelvic angle (IPA) less than 30°.Methods Thirty-six patients with inferior caliceal calculi on whom flexible ureteroscopic procedures were performed between November 2009 and June 2015 were reviewed.The mean age of the patients was 52.1 years (34-71),with the mean stone diameter of (1.5 ± 0.8) cm (1.2-2.6 cm).IPA was smaller than 30° in all 36 cases,which confirmed by CTU examination.IPA was less than 10° in 15 patients,between 11 ° and 20° in 13 patients and between 21 ° and 30° in 8 patients.Results The success rate was 63.9％ (23/36 patients) in patients with IPA smaller than 30° after first session of procedure,and the stone free rate reached 100％ after the second session of procedure.The mean operation duration was (95.5 ± 31.4) min(51-127 min).The mean hospital stay after operation was(4.1 ± 1.2)days (3-5 days).No major complications were recorded and no patients needed to convert to open surgery.Double J tube was removed after 4 weeks postoperatively.Patients were followed up for 4-12 months,during which ultrasound and CT scan were used for stone detection.Conclusions The small IPA (＜30°) negatively affected the SFR in the first session operation.However,its negative effect was solvable by using modern endoscopes.A complete stone clearance was achievable even in case of unfavorable anatomic conditions in experienced hand.
