Objective To study the clinical characteristics of elderly sleep apnea syndrome (ASA). Methods 329 SAS patients diagnosed by 7-hour polysomnography(PSG) were classified into the aged and the middle aged groups. Results Both the body mass index(BMI) and neck circumference were significantly lower in the aged group than those in the middle aged group(P

Objective To study the clinical characteristicsand perioperative managementof complicated placenta increta, effectively reduce the maternal adverse perinatal outcomes. Methods Retrospective analysis 25 cases of complicated placenta increta between January 2013 and December 2015 in the Third Affiliated Hospital Of Guangzhou Medical University. Grouped into preoperative line 9 cases of ureteral catheter group and without catheter group 16 cases; Conventional hysterectomy group of 17 cases and the posterior hysterectomy group of 8 cases , compare the operation time , postpartum hemorrhage , blood transfusion amount , bladder injury or ureteral injury rate , rate of transferred to the ICU and hospital stay. Results 76% appear repeatedly painless vaginal bleeding during pregnancy , 56% appear bleeding before delivery. Prenatal diagnosis of 17 cases (68%). The preoperative line cystoscopy + bilateral retrograde ureteral catheter or after the posterior hysterectomy , shorter operation time , less postpartum hemorrhage , reduce blood transfusion volume , no urinary tract injury rate, transferred to the ICU rate is low, the difference was statistically significant (P < 0.05). Conclusions We should attach importance to repeated painless vaginal bleeding , improve prenatal diagnostic rate of complicated placenta increta. The perioperative managementis more comprehensive , effective and standard participation , preoperative ureteral catheter and the posterior hysterectomy can effectively reduce the maternal adverse perinatal outcomes.

Objective To screen and diagnose obstructive sleep apnea-hypopnea syndrome (OSAHS) in elderly males by obesity index using receiver operating characteristic(ROC) curves. Methods Data of 402 consecutive elderly male patients who underwent polysomnography from 2001 to 2008 were collected. The relationship between apnea hypopnea index(AHI) and obese indexes such as body mass index (BMI), neck circumference (NC), waist circumference (WC) and waist-to-hip ratio (WHR) were analyzed by Pearson's correlation. ROC curves were used to determine the best cutoff values to screen and diagnose OSAHS, and their priority was compared by area under curve (AUC). A two-tailed P value less than 0.05 was considered statistically significant. Statistical analysis was carried out with SPSS version 13.0. Results (1) AHI was positively correlated with BMI (r=0.241,P<0.001), NC(r=0.201,P<0.001), WC(r=0.210,P<0.001) and WHR(r=0. 097,P>0.05)) in elderly male patients. The area under curve (AUC) of BMI, NC, WC and WHR was 0.61, 0.58, 0.51 and 0.45 respectively, and P value was 0.001,0.060,0.840 and 0. 250 respectively. Only BMI was competent in screening and diagnosing OSAHS in elderly male adults; (2) The optimal value of BMI was 22.0 kg/m~2 in screening OSAHS with specificity 90% and rate of missed diagnosis 10%; (3) The optimal value of BMI was 29.0 kg/m~2 in diagnosing OSAHS with specificity 90% and rate of missed diagnosis 10%. Conclusions BMI more than 22.0 kg/m~2 could be the reference standard to screen OSAHS and BMI more than 29.0 kg/m~2 to diagnose OSAHS in elderly men.

OBJECTIVETo investigate the controlling effects of bionic glue on Paratrioza sinica.

METHODP. sinica and bionic glue were chosen as materials to investigate the adhesive rate, mortality rate, and study the effects of behavior of P. sinica and growth of leaves sprayed with bionic glue.

RESULTSpraying of the bionic glue can significantly increase the adhesive rate of P. sinica with no obviously repellency, and it can be used to control the adults of P sinaca in field with no significant effect on the growth of wolfberry leaves.

CONCLUSIONBionic glue has significant controlling effects on adults of P. sinica, it can be used as an eliminator of adults of P. sinica in field at the beginning of the vegetation season to suppress of the development of P. sinica population.
