Objective To summarize the clinical features of patients with ovarian tumor associated anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis,and to explore the influence of operation patterns on the prognosis.Methods The clinical data of ovarian tumors with anti-NMDAR encephalitis in the Third Affiliated Hospital of Sun Yat-sen University from January 2009 to December 2018 were collected,and the clinical characteristics,treatment and prognosis were analyzed.Results A total of 110 patients with ovarian tumors and anti-NMDAR encephalitis were collected.All patients were positive for anti-NMDAR antibodies in serum and/or cerebrospinal fluid.The age of onset ranged from 10 to 35 years (24.6 ±5.7).About 60.9％ patients'initial symptom was psychosis.The main clinical features were psychosis (97.3％),seizures (83.6％),conscious disturbance (72.7％),autonomic dysfunction (64.5％),dyskinesia (64.5％),central hypoventilation (54.5％) and impaired memory (31.8％).Most patients'symptoms were relieved after surgery and immunotherapy.Postoperative pathological results revealed that ovarian teratoma accounted for 97.8％ of the ovarian tumor.The prognosis of patients with surgery was better than the patients without surgery,with statistically significant difference (P ＜ 0.05).The prognosis of patients with adnexectomy was better than the patients with ovarian tumor excision,with statistically significant difference (P ＜ 0.05).Conclusions Anti-NMDAR encephalitis,with psycho-neurological symptoms as dominant manifestation,is usually associated with ovarian tumor.For young female patients with psychosis,clinicians should be alert to the possibility of anti-NMDAR encephalitis and screen for tumor.Patients with adnexectomy and immunotherapy can get a better prognosis.

Objective To explore the epidemiology characteristics of endometrial cancer (EC).Methods We retrospectively analyzed 10081 patients diagnosed with EC from 62 hospitals between 2000 and 2010 in Guangdong province.Results The mean age at diagnosis was 52.8 ± 9.3.The proportion were 19.3％,64.2％,16.6％ in patients with ages ≤45,＞ 45-60,＞ 60 respectively.From 2000 to 2010,the mean ages at each year were no statistic significance.The number of cases of EC were positively correlated with years(r =0.964,P ＜ 0.001).The number of cases of patients with ≤ 30 years old (r =0.857,P =0.001),≤35 years old (r =0.866,P =0.001),≤40 years old (r =0.952,P ＜ 0.001),≤ 45 years old (r =0.952,P ＜0.001) were positively correlated with years.The ratios of patients with ≤30 years old (x2 =10.390,P =0.407),≤35 years old (x2 =11.651,P =0.309),≤ 40 years old (x2 =17.329,P =0.067),≤45 years old (x2 =5.154,P =0.881) during these eleven years were no statistic significance.The ratios of type Ⅰ EC at 2000-2010 were no statistic significance.Conclusions EC often present in patients aged from ＞ 45-60 years old.The case number of EC showed an increasing trend.However,the proportion of young patients was stable.The endometroid adenocarcinoma was the main histological type of EC.
