Objective To explore the application value of CA125 detection in the diagnosis and treatment of ovarian endometriosis cyst,to provide a reference for clinical diagnosis and treatment.Methods 51 patients with ovarian endometriosis cyst were selected as the observation group,and 51 patients with non endometriosis of benign ovarian cyst were selected as control group.The serum CA125 level was detected and compared between the two growps.Results Before operation,the serum CA125 level of the observation group was (95.29 ± 55.47) U/ml,which was significantly higher than that of the control group (17.96 ± 6.82) U/ml (P ＜ 0.05).In the observation group,serum CA125 level of patients with endometriosis clinical pathological stage Ⅱ-Ⅳ was significantly higher than that of patients with stage Ⅰ (P ＜ 0.05).The endometriosis clinical TNM stage was positively correlated with preoperative serum CA125 level in the observation group (r =0.8795,P ＜ 0.05).The preoperative serum CA125 level in patients with dysmenorrhea score 1 point,2 points,3 points was significantly higher than that in patients with dysmenorrhea score 0 point (P ＜ 0.05).The preoperative serum level of CA125 was positively correlated with dysmenorrhea score in the observation group (r =0.5594,P ＜ 0.05).Conclusion The detection of serum carbohydrate antigen CA125 level has important value in diagnosis,treatment and prognosis of ovarian endometriosis.

Objective To compare the risk effects of different antiplatelet therapies on gastrointestinal injury and summarize the endoscopic characteristics of gastrointestinal mucosal injury in the elderly. Methods The dyspepsia symptoms, gastrointestinal bleeding and endoscopic findings were retrospectively evaluated among 577 patients who received the antiplatelet therapy with aspirin and/or clopidogrel. Results The risk of dyspepsia symptoms and gastrointestinal bleeding was slightly higher in clopidogrel group than in aspirin group (both P＞0.05, x2=0.48, 0.72), and OR (95% CI): 1.10 (0.59-2.07) and 1.74 (0.48-6.33), for the risk of dyspepsia symptoms and gastrointestinal bleeding, respectively. In aspirin plus clopidogrel group, the risk of dyspepsia symptoms had no significant increase as compared with aspirin or clopidogrel group (x2=0.37, 0.03, for aspirin or clopidogrel group, respectively, both P＞0.05), but the risk of gastrointestinal bleeding was significantly higher than in aspirin group (x2=5.43, P＜0.05), OR (95% CI): 4.77 (1.15-19.79) and slightly higher than in clopidogrel group (P＞0.05). In this study, 57 patients received endoscopy and the detection rate of erosion or ulcer was 78.9%. Erosion (61.4%) was most in the gastric antrum; gastric ulcer (10.6%) located in gastric antrum and angle; duodenal ulcer (18.0%) located in bulb. In patients with dyspepsia symptoms erosion (70.5%), were most likely found but patients with gastrointestinal bleeding showed mainly ulcer (69.2%). Conclusions In the elderly the use of clopidogrel alone is not safer than low-dose aspirin and the combination would increase the risk of gastrointestinal bleeding. The detection rate of erosion or ulcer is high in patients with symptoms. Patients with dyspepsia symptoms most likely show erosion, but patients with gastrointestinal bleeding have mainly ulcer and complex ulcers more common.
