Objective To explore the safety and feasibility of blocking blood flow in interstitial tubal pregnancy treated with laparoscopic opening-taking embryo operation.Methods The clinical data of 98 patients with lump interstitial tubal pregnancies (requesting reserve procreate function) from January 2006 to December 2013 were chosen.Among them,56 patients were in study group (January 2010-December 2013) and 42 patients were in control group (January 2006-December 2009).All patients were treated with opening-taking embryo by laparoscopic operation.In study group,we first blocked the uterine artery and ovarian artery blood supply of pregnancy lump,secondly opened pregnancy lump and stripped gestation sac with hydraulic pressure separation during operation.Whereas,in control group,we opened pregnancy lump and taken out pregnancy tissues according to convention method without blocking blood flow.Operation success rate,operation blood volume,operation time,persistent ectopic pregnancy (PEP) happening rate,fallopian tube unobstructed information,and pregnancy information after operation were compared between two groups.Results In study group,operation success rate was 96.4％,which was significantly higher than that in control group (61.9％) (P ＜0.01) ; operation blood volume was[(20.7 ± 10.4)ml],which was significantly less than that in control group [(60.7 ± 18.4) ml] (P ＜ 0.01) ; operation time [(46.6 ±14.2) min] was significantly shorter than that in control group [(66.5 ± 19.4) min] (P ＜ 0.01) ; there was no PEP in study group,while there were 5 PEPs (11.9％) in control group.Fallopian tube unobstructed rate after operation in study group (76.9％) was significantly higher than that in control group (41.7％) (P ＜ 0.05).Conclusions Application of blocking blood flow in opening-taking embryo by laparoscopic operation on lump interstitial tubal pregnancies is safe and effective.

Aim To investigate the antinociception, tolerance and withdrawal abstinence of δ/μ/κ opioid receptor triple agonist KUST201 ( DPI-125 ) in rats. Methods Male Sprague-Dawley rats were used to de-termine the time course of analgesic effects and ED50 effects of co-administration of naltrindole were assessed as well. In withdrawal experiments, KUST201 was ad-ministrated twice daily for 3 d with increasing doses each day. On the 4th day, the rats were given a single dose, challenged with naloxone 3 h later, and signs of abstinence were monitored. Results The ED50 values of KUST201 were 0. 34 mg·kg-1 in tail-pinch test and 0. 68 mg · kg-1 in hot-plate test. The antinociception actions of KUST201 started to decrease 1 h after ad-ministration, and disappeared after 2 h. In chronic tol-erance experiments, the antinociception actions started to decrease on d 3 , and completely disappeared on d 7 . Naltrindole could reduce the antinociceptive action of KUST201. In withdrawal experiments, abstinence scores increased significantly in the dose range between 2~8 times of tail-pinch ED50 . Conclusion Compared with previously reported δ/μ/κ triple agonist DPI-3290 , KUST201 exhibits similar antinociceptive effects in rats. The chronic tolerance to KUST201 actions de-velops less quickly, but the abstinence scores of KUST201 are slightly higher. The activation of δ-opi-oid receptor can synergistically enhance the antinoci-ception mediated by μ-receptor.

Objective To explore the relationship among social support, postpartum depression and quality of life of puerperal women. Methods A total of 348 puerperal women were investigated with Postnatal Social Support Questionnaire,Edinburgh Postnatal Depression Scale (EPDS) and WHO Quality of Life-BREF (WHOQOL-BREF). Results Pearson correlation analysis showed that there was a significant positive correlation between social support and the quality of life (r=0.483, P < 0.01), and a significant negative correlation to postpartum depression (r=-0.243, P < 0.01),and a significant negative correlation between postpartum depression and quality of life (r=-0.408, P<0.01). Intermediary effect of postpartum depression was tested. Conclusions A good social support system is benefit to improve depression scores for EPDS, and promote the life quality in puerperal women.

Objective To investigate an effective endoscopic management of biliary anastomotic stric-tures (AS) following orthotopic liver transplantation (OLT) and to evaluate the factors which may effect the ontcome. Methods Sixty-five patients, who were diagnosed as AS 3 months after OLT, underwent ERCP. Af-ter adequate dilation of the narrowing bile ducts, plastic stents, as many as possible, were inserted across the strictures and kept in place for at least six months. Results A total of 90 consecutive endoscopic procedures were performed in 65 patients. Before stents placement, the strictures were dilated by catheter or balloon (di-ameter range: 6-10 mm), or not dilated, according to the status of the bile ducts. An average of 3 (ranging from 2 to 6) plastic stents were placed with mean total size of 22.8 F (range 14-42 F), and the stents were kept for 8. 0 months on average (range 0.2-37.8 months). Of 90 procedures of stents placement, 54 (60%) were followed by stents removal and cholangiography, which confirmed stricture resolution in 26 (48.1%). The stricture resolution rate was 81.0% (17/21) in patients who underwent balloon dilation followed by more than 3 stents (> 21 F) for at least 3 months. Stricture re-occurred in 3 patients after stents removal, in whom stents were kept less than six months. Conclusion Endoscopic sequential intervention is effective for post-OLT biliary strictures according to the stage and grade. Radical dilation with maximal stenting can lead to complete resolution of AS. To achieve better result, if possible, balloon dilatation followed by three or mere endoprothe-ses (of at least 21 F) sustaining for more than 6 months is necessary.

ObjectiveTo retrospectively investigate the clinical features of the biliary tract complieations after living donor liver transplantation (LDLT) and the efficacy of endoscopy.MethodsThe LDLT patients with hiliary eomplieations were given endoscopic retrograde eholangiopanereatography (ERCP) and endoscopic therapies were carried out according to the result of eholangiogram.ResultsTwenty-one patients,among whom 43.8% were at early postoperative stage,underwent 28 endoscopic procedures.Nineteen patients (90.4%) had biliary anastomotic strictures with angled malformation.Bile leakage was found in 9 patients (42.9%).The success rate of endoscopic therapy was 85.7% ,including nose-bile drainage in 5,stent placement in 10,balloon dilatation and/or multiple stents placement in 9 and bile collection drainage in 2.During follow-up,leak heal was confirmed in 3 patients and stricture resolution was achieved in another 2 eases. ConclusionBiliary complication is relatively common in the early stage after LDIX,and severe anastomotie stricture with angled malformation is most frequently seen, usually associated with bile leakage. Series of endoscopic interventions with the strategy of "leak first,and then stricture"might achieve satisfactory outcome.

Acute appendicitis is one of the most common acute abdominal diseases in surgery. Due to its urgent onset and rapid progress, timely diagnosis and early treatment are beneficial to the prognosis of patients. The diagnosis of acute appendicitis should be based on the characteristics of different populations, based on clinical symptoms, physical examination, laboratory examination, and imaging methods. Anti-infection treatment should be started as soon as possible in the early stage, and antibiotics should choose effective drug treatment with both anaerobic bacteria and aerobic bacterial infection. Appendectomy is still the most effective treatment for acute appendicitis. In the case of uncomplicated abdominal infection such as simple and non-perforated appendicitis, antibiotic treatment may be chosen, but the development needs to be closely observed. Laparoscopic appendectomy is the first choice, but in pregnancy patients should be cautious. Emergency surgery is required for acute perforated appendicitis and attention should be paid to intraoperative abdominal flushing. Immediate surgical treatment of appendiceal abscess may involve the risk of partial ileectomy. Antibiotic treatment is recommended, with percutaneous abscess puncture and drainage if necessary.

BACKGROUND:Among many transplanted cells,adult autologous bone barrow-derived mononuclear cells have beenused in clinical practice because they are easy to be obtained,without immunological rejection and ethical disputationand other advantages.How to distinguish donor cells from receptors and observe the survival of donor cells following stem cell transplantation still trouble people.OBJECTIVE: superparamagnetic iron oxide (SPIO)particles-labeled bone marrow-derived mononuclear cells from minipigs were used to observe the feasibility of in vivo tracking with magnetic resonance imaging(MRI).DESIGN:A controlled observation experiment.SETTING:Institute of Cardiovascular Disease,Zhongda Hospital Affiliated to Southeast University.MATERIALS:This experiment was carried out in the Institute of Cardiovascular Disease,Zhongda Hospital Affiliated to Southeast University between April 2006 and August 2006.Healthy Chinese minipigs,aged 3 to 4 months,weighing from 20 to 30 kg,were provided by the Experimental Animal Center of Southeast University[SYXK(Su)2002-0012].METHODS: Autologous bone marrow-derived mononuclear cells of minipigs were isolated and cultured. Bone marrow-derived mononuclear cells in the suspension were traced with SPIO particles.Ferrum in the cells were shown by Prussian blue staining, and cell viability was evaluated by trypan blue exclusion method. Eleven minipigs used for preparation of model of myocardial infarction were divided into experimental group(n=9)and control group(n=2).By means of percutaneous left or right cervical artery or femoral artery puncturation, 1.5 to 2.0 mm balloon was used to occlude 1/3 left anterior descending branch,304 to 405 kPa,60 minutes later,ischemic preconditioning was conducted 3 tO 4 times before operation. When pig models of myocardial infarction were successful that was proved by surface electrocardiogram,bone marrow-derived mononuclear cells were percutaneously injected into coronary artery.Coronary arteriography was performed through femoral artery acupuncture at 24 hours after establishing infarction models.Suspension of bone marrow-derived mononuclear cells was perfused into coronary artery with OTW catheter.Then,the injector and OTW catheter for containing cells were rinsed with normal saline containing heparin and infused with the residual cells within 10 minutes.Non-labeled cells were perfused in 2 minipigs of control group by the same method.Postoperatively, bone marrow-derived mononuclear cells were traced by magnetic resonance and compared with Prussian blue-stained myocardial tissue sections.RESULTS: Seven minipigs of experimental group and one minipig of control group were Involved in the final analysis.One of each group was used for preparation of model of myocardial Infarction.One minipig of experimental group died from anesthetic accident before magnetic resonance.①Bone marrow-derived mononuclear cells all were nearly labeled by SPIO particles. Bone marrow-derived mononuclear cells could further proliferate in culture medium containing Fe2O3-PLL without obvious changes of cellular shape. ②T2+WI showed that 5 of 8 models of myocardial infarction presented fuzzy low-echo signal region in peripheral myocardial infarction after transplantation of labeled cells and the low-echo signal disappeared 4 weeks Iater. Ex vivo T2+WI sequence showed there was a dot-distributed low-echo signal region in the peripheral infarction region.③It was found in histological examination that 5 models(cell number over 106) had Prussian blue-positive cells,which distributed the same as those in magnetic resonance signal reducing region.CONCLUSION:SPIO particles-labeled bone marrow-derived mononuclear cells are safe and effective;T2+ WI is sensitive to tracing SPIO particles-labeled bone marrow-derived mononuclear cells;Magnetic resonance can in vivo trace SPIO particles-labeled stem cells transplanted through coronary artery,magnetic resonance signal change is related with the number of stem cells and division growth.
