The activity of matrix metalloproteinases (MMPs) in the uterine flushing and endometrial tissue of normal adult women wearing FCu-IUD (fixed Cu-IUD) or FICu-IUD (indomethacin-releasing FCu-IUD) was observed by using zymography on SDS-PAGE containing gelatin. The results showed that the activity and kinds of MMPs in FCu-IUD group were increased significantly as compared with themselves before being inserted FCu-IUD. However, compared with the FCu-IUD group, the activity of some kinds of MMPs in the FICu-IUD group was decreased significantly. These data suggest that IUD can enhance the activity of MMPs in human endometrium, intermediated by prostaglandins, and MMPs may have relation to IUD-induced menorrhagia and indomethacin reduces IUD-induced menorrhagia by partly inhibiting MMPs synthesis.

OBJECTIVETo study the Cupric ion release characteristics of different copper raw materials in intrauterine device in vitro by ICP. Reveal the relationship between purity and shape of Cu-IUD copper and copper ion release.

METHODSAccording to a certain proportion, the copper raw materials were 100 times diluted into the simulated uterine solution at 37 +/- 0.5 degrees C. Replaced medium at certain time points and collected soaking liquid. Using ICP analyzed the concentration of copper ion released.

RESULTSThe largest daily release of copper ions was in the first 7 days. There was no statistically significant difference between the copper ion release amount of 99.99% and 99.95% purity copper wire (P > 0.05). The release of copper ion of the copper wire was far greater than that of the copper pipe in early stage (P < 0.01). The release amount decreased and stabilized at 56 day.

CONCLUSIONRelease characteristics of copper ion could effectively analysis by ICP. And in the same area, the release amount of copper ions of copper wire was greater than that of copper pipe.

Two kinds of Cu-containing intrauterine contraceptive device (Cu-IUD) has been evaluated through the study on the release of copper ion and corrosion of copper surface in artificially formulated fluid. The result showed that the copper ions were released profusely from the stainless steel stents Cu-IUD in the first week of soak (25-12 microg/d), and then it became slowly and steady. The release of the copper ions from the titanium nickel shape memory alloy stents Cu-IUD were always slowly and steady in two months (0.5-5 microg/d). It obviously shows that the corrosion on copper surface of stainless steel stents Cu-IUD were more serious than titanium nickel shape memory alloy stents Cu-IUD by using 200 times microscope testing before and after soaking in formulated fluid.

OBJECTIVE: To evaluate the efficacy and adverse effects of levonorgestrel-releasing intrauterine system (Mirena) in the treatment of adenomyosis. METHODS: The clinical data of 75 patients with adenomyosis who had Mirena insertion in Women's Hospital,Zhejiang University School of Medicine from September 2013 to December 2013 were retrospectively analyzed. The patients were followed up to 39 months. The efficacy and adverse effects were assessed. RESULTS: Pictorial Blood Loss Assessment Chart (PBAC) scores were decreased significantly after Mirena insertion both in patients with menorrhea (118±13 vs. 29±33, <0.01) and normal menstruation (82±15 vs. 14±13, <0.01); the patients with menorrhea showed a more significant decrease in PBAC score than those with normal menstruation (90±35 vs. 69±19,<0.01). The visual analogue scale (VAS) score decreased significantly after Mirena insertion compared with pre-treatment[7(6,7) vs. 1(0,2), <0.01]. The expulsion of Mirena occurred in 18 cases (24.0%); 9 cases (12.0%) had no effect and 28 cases (37.3%) had changes of menstruation patterns. Multivariate Cox regression analysis showed that the expulsion of Mirena was not associated with post-treatment VAS score, PBAC score before and after treatment or menstrual stabilization time (all >0.05). CONCLUSIONS Mirena is effective and safe in the long term management of adenomyosis, but about one third patients may require further treatment because of the expulsion or ineffectiveness of Mirena.

Intrauterine contraceptive device (IUCD) is common choice for contraception. Migration of IUCD is one of the complications that are encountered. Here we report a case of IUCD migration to the sigmoid colon. A 39-year-old Malay lady carrying a copper T type of IUCD presented with missing thread then underwent examination under anaesthesia, proceeded to hysteroscopy but failed removal. Abdominal ultrasound detected it in the left lower quadrant of abdomen. She then underwent diagnostic laparoscopy where the device was found to be embedded in the sigmoid colon. Technical difficulty necessitated conversion to mini laparotomy and sigmoidotomy to remove the IUCD and the bowel closed primarily. IUCD is a relatively simple and safe contraceptive procedure but possible complications are bleeding and pain that usually co-exist, pelvic infection, expulsion and perforation. Investigations should be based on clinical suspicion and migrated IUCD in symptomatic patients should be surgically removed whereas, asymptomatic patients can be managed conservatively under certain circumstances. However in the presence of a concurrent pathology that requires exploration then retrieval of the migrated IUCD should be undertaken.

Background: Progressively increasing population of the country leads to unmet needs for responsible parenthood. This is reflective to reproductive age women with unplanned pregnancies which may consequently lead to maternal morbidity and mortality and adverse perinatal outcomes. Provision of family planning methods is implemented. One of the temporary methods of Long Acting Reversible Contraception (LARC) is Intrauterine Contraceptive Device (IUD). The effectiveness is similar to tubal sterilization with its perfect use. However, one of the drawbacks is dealing with its expulsion which affects its efficacy. Objective: The study determined the expulsion rate between Immediate and Early postpartum IUD insertion after vaginal delivery. Expulsion rate was evaluated during the following periods: prior to discharge, after 4 weeks, after 12 weeks and 24 weeks post-insertion. Methodology: This was an Observational Cross Sectional Study conducted for a year designed to collect data among patients who had IUD insertion after vaginal deliveries in a 6-month period of follow up. Sample size was computed using epi info 7.0. Finite Population Collection was derived to meet the population size available which resulted to 159 participants. Randomization was initiated to classify between immediate and early IUD insertion. Expulsion was observed during follow up at the family planning center of the institution Results: This data showed no direct correlation in the expulsion rates between early and immediate postpartum IUD insertion. The expulsion rate was 6.25% for Immediate and 5.55% for Early IUD insertion respectively. There were no expulsion observed beyond 12 weeks post insertion. Relationship between early/immediate IUD insertion and expulsion rate was investigated using Chi square test. Conclusion Improved education and heightened awareness among reproductive aged women would initiate higher acceptance of IUD during postpartum period. Proper and improved technique of IUD insertion during postpartum period may decrease expulsion rate hence promoting better utilization of this family planning method.

OBJECTIVETo investigate the apoptosis-related mechanisms of levenorgestrel-releasing intrauterine system (LNG-IUS), oral medroxyprogesterone (MPA), and injective gonadotrophic hormone releasing hormone agonist (GnRHa) on eutopic endometrium of patients with endometriosis. Methods We collected the samples of endometrium from patients with endometriosis before operation and after insertion of LNG-IUS, administration of oral MPA, or injection of GnRHa. The ultrastructure of endometria was observed and compared by electron microscopy. Apoptotic cells were assessed by the terminal deoxynucleotidyl transferase-mediated deoxy-UTP nick-end labeling (TUNEL) assay, and the expressions of Bax, Fas, and Fas-L mRNA were determined by semi-quantitative reverse transcription-polymerase chain raction. Results After have been exposured to LNG-IUS, the apoptotic rate of endometrial epithelial cells and stromal cells increased from (24. 4 +/- 35.0)% to (51.0 +/- 37.8)% (P = 0.027) and (35.3 +/- 30.2)% to (76.4 +/- 11.2)% (P = 0.008), respectively. The degree of apoptosis under transmission electron microscopy was in an order of GnRHa > LNG-IUS > MPA. The expression of Fas-L mRNA in eutopic endometrium of patients with endometriosis was significantly higher than that of the normal control (P < 0.05). The expressions of three apoptosis-related proteins had no significant difference.

CONCLUSIONMedical treatments can increase the apoptosis of eutopic endometrial cells, and such effect was strongest in GnRHa and relatively weaker in LNG-IUS and MPA.
