Objective To evaluate the efficiency of levonorgestrel-releasing intrauterine system (LNG-IUS) in the treatment of recurrent endometriosis after conservative surgery or conservative surgery combined with medical treatment. Methods Twenty-three patients with recurrent endometriosis after conservative surgery or conservative surgery combined with medical treatment were treated by LNG-IUS. All patients rejected further operation and had no desire of fertility. The visual analogue scale (VAS) scores of pain, menstrual model, weight and serum CA125 level and the volume of ovarian endometriotic cysts before and after 3, 6, 12, 24 and 36 months of treatment were recorded and compared. Results ( 1 ) VAS score:after 12 months of using LNG-IUS, dysmenorrheal, chronic pelvic pain or dyspareunia were relieved significantly. VAS score were dropped from 5.9 ± 2. 3,4. 3 ± 2.0 to 1.0 ± 0. 7,1.4 ± 1. 1 ( P ＜ 0. 01 ). ( 2 )Volum of cysts :after 6 months of using LNG-IUS, the volume of recurrent ovarian endometriotic cysts in 11 patients were reduced from ( 11.4 ± 6. 1 ) em3 to ( 5. 5 ± 3.4 ) em3 significantly ( P ＜ 0. 01 ). At 12 months of follow-up, it suggested that 2 patients' ovarian endometriotic cysts disappeared. At 24 months follow-up,9 patients ovarian endometriotic cysts disappeared ( 3 ) CA125: serum CA125 decreased from ( 65.5 ± 19. 6 )kU/L to (42. 1 ± 13.6) kU/L at 6 months after treatment remarkably (P ＜ 0. 01 ). Continued to decrease after 12 months and then become steady. Irregular bleeding and spotting was the main side effects, weight gain was also observed in few patients. Conclusions LNG-IUS could be used in treatment of recurrent endometriosis after conservative surgery or conservative surgery combined with medical treatment effectively. It could relieve pain, reduce the level of CA125 and decrease the size of ovarian endometriotic cysts. LNG-IUS seems to be an effective, safe, and long term treatment for endometriosis with fewer side effects and better compliance.

Inflammatory bowel disease(IBD)is no cure at present,and only drugs and surgery can relieve symptoms,delay and reduce recurrence.Therefore,it is very important to monitor the disease activity.Glycocalyx,a polyglycoprotein complex covering luminal side of vascular endothelial cells,is supportive in maintaining the intestinal mucosal barrier,and inflammation leads to its structural damage.This review introduces currently available non-invasive biomarkers of clinical importance for IBD in laboratory testing,and analyzes the value of serum glycocalyx injury markers(syndecan-1,HS and HA)in the diagnosis or monitoring of IBD.

Objective To explore the influence of Yoga exercise on the work stress and coping styles of operating room nurses. Methods A total of 77 nurses were selected working in the operating room of our hospital,and all the nurses were randomly divided into observation group(38 cases)and the control group (39 cases). The nurses of observation group did Yoga exercise regularly,while the nurses of control group did not make any Yoga workout regularly. We used psychological stress scale( CPSS)to assess anxiety of two groups nurses before and after the intervention,and investigated every nurse's pressure coping style respectively before and after care. Results Pressure improvement mark in the observation group had been greatly improved after Yoga exercise intervention(16. 203 ± 4. 218),while it was(3. 127 ± 1. 037)in the control group with statistical significance( t = 3. 012,P < 0. 05);the improvement of anxiety in the observation group was significantly better than that of the control groups,the difference had statistical significance(P < 0. 05);the stress coping style of observation group were obvious improved after the intervention compared with that of the control group(P < 0. 05). Conclusions Yoga exercises can improve the working stress and coping operating room nurses effectively.
