Objective To analyze the outcome of patients receiving intrauterine insemination with husband sperm,in order to evaluate the effect of relative factors on pregnancy rate after intrauterine insemination. Methods Ninety-eight infertile couples who received intrauterine insemination in the Affiliated Hospital of Nantong University from March 2013 to May 2014 were selected as our subjects and 181 cycles were included. The information including clinical factors including maternal age,infertile time,infertile causes, ovulation induction protocol,time of insemination and postwash total motitle sperm(TMS)and pregnancy rate were recorded. Results (1)Totally 26 patients received clinical pregnancies,and clinical pregnancy rate(CPR) was 14. 36% per cycle. With age increase pregnancy rate decreased( χ2 = 1. 654 9,P = 0. 647).(2)The pregnancy rate of the patients was the same within the infertile time( χ2 = 1. 588 5,P = 0. 662).(3)The pregnancy rate of the patients with secondary infertility was lower than that of the patients with primary infertility,but there was no significant difference(χ2 = 0. 923 3,P = 0. 337).(4)The pregnancy rate of ovulation induction cycles was lower than that of nature cycles,but there was no significant difference(χ2 = 2. 222 0,P= 0. 136).(5)Postwash TMS was showed the same trend(χ2 = 0. 643 4,P = 0. 422). Conclusion In terms of intrauterine insemination with husband sperm,age,infertile time,infertile types,ovulation induction protocol and posrwash TMS can affect pregnancy rate,and the effects of various factors should be considered comprehensively in the process of therapy.

ObjectiveTo summarize the clinical experience of simultaneous pancreas and kidney transplantation (SPK) after liver transplantation for patients with diabetes and uremia.MethodsThe clinical data of two patients who received SPK after liver transplantation were retrospectively analyzed.The two male patients had type 2 diabetes mellitus before liver transplantation,and suffered from endstage uremia due to diabetic nephropathy and immunosuppressant-induced toxicity.Rapid technique for combined abdominal multiple viscera procurement was performed.Kidneys,pancreas,duodenum segment and spleen were procured.Renal allograft was placed in the left iliac fossa,whereas pancreas allograft in the right iliac fossa. The pancreatic allograft exocrine secretion was drained into the proximal jejunum via a side-to-side duodenojujunostomy. Quadruple immunosuppressive regime including IL2 receptor monoclonal antibody induction,tacrolimus (Tac),mycophenolate mofetil (MMF) and steroid were used in case 1,and ATG and methylprednisolone were used in case 2.ResultsSPK was successfully applied to these two patients without serious surgical complications such as pancreatitis,graft and pancreatic fistula. The immunosuppressive regimen was based on tacrolimus with ATG induction,MMF and steroids.In the second case,serum creatinine level was decreased to the normal range within 1 week after the operation and then elevated continuously even he received empirical anti rejection treatment,Tac was tampered and rapamycin was used when the renal graft biopsy indicated drug toxicity,and creatinine level was decreased 3 weeks after the operation and recovered to the normal range at 5th week post-transplant. Both of the two patients achieved euglycemia with insulin independence about 10 days after the operation.And now these two patients have been followed up for 36 and 9 months,and the grafts function of the liver,kidney and pancreas was normal. Conclusion Immunologic reaction in patients undergoing simultaneous pancreas and kidneytransplantationafterlivertransplantationseemsmorecomplex, andareasonable immunosuppressive regimen is important to improVe the outcome.

Objective To explore the causes and management of intra-abdominal hemorrhage after orthotopic liver transplantation (OLT). Methods Clinical data of 638 OLT patients were analyzed retrospectively from January 2004 to December 2008 in the First Affiliated Hospital of Sun Yat-Sen University. The diagnosis and treatment of postoperative intra-abdominal hemorrhage after OLT were reviewed. Results Among the 638 patients, 53 suffered from posttransplant intra-abdominal hemorrhage,the morbidity was 8. 3% (53/638). Thirty-one cases suffering from bleeding on raw surfaces or around the liver due to impairment of coagulation function were treated by non-surgery methods, 22 cases who suffered from active postoperative intra-abdominal hemorrhage due to surgical factors underwent laparotomy and bleeding control operation after failure of anti-shock treatments such as hemostatic drugs, blood reperfusion.Among the 53 patients who suffered from intra-abdominal hemorrhage, 12 patients died, and the main causes were serious infections and multiple organ dysfunction syndrome. The mortality associated with intraabdominal hemorrhage was 22. 6%. Conclusions Intra-abdominal hemorrhage at different locations were found after OLT, and the fatal rate is quite high. Timely and appropriate treatments especially laparotomy may improve the prosnosis of these patients.

ObjectiveTo define the resistance rate and epidemiology of Gram-negative bacilli (GNB) of bloodstream infections (BSI) after liver transplantation. MethodsFrom Jan. 1998 to Dec.2009,a retrospective analysis of GNB in liver transplants was conducted. Bacterial, CMV and fungal infections were prevented by piperacillin/tazobactam, ganciclovir, fluconazole postoperatively. Bacterial inoculation,isolation and culture were mandated by national test standard. Vitek 2 Compact was used to evaluate identification and antimicrobial susceptibility testing. ResultsEighty-eight BSI occurred in 83 patients of the 768 patients,in which a total of 88 GNB were isolated. The incidence was 10. 8 %(83/768) ,and the most frequent pathogens were Escherichia coli (37 strains) and Klebsiella spp (18strains). The rate of infection (23. 9 %) was high in the interval of 1998-2000, and then decreased to 12. 4 % or below. Carbapenems and Piperacillin/tazobactam were the most consistently active against the Escherichia coli and Klebsiella spp, while resistance rate of Escherichia coli to Ciprofloxacin,Gentamycin, Ampicillin-clavulanic acid or Klebsiella spp after 2005 to Ciprofloxacin, Ticarcillinclavulanic acid was over 60 %. ConclusionGNB after liver transplantation were resistant to agents but active to Carbapenems and Piperacillin/tazobactam commonly, in which Escherichia coli and Klebsiella spp are common.

BACKGROUND: Simultaneous pancreas and kidney transplantation (SPK) has been considered an effective therapeutic means of diabetes mellitus (including type 1 and type 2) combined with end stage uremia. Because the pancreas possesses high immunogenicity, so a feasible immunosuppressive regimen is a key to successful pancreas transplantation. OBJECTIVE: To investigate the feasible immunosuppressive regimen after simultaneous pancreas and kidney transplantation (SPK). METHODS: From January 2005 to June 2009, 9 patients with diabetic nephropathy and end stage uremia, consisting of 5 males and 4 females, received SPK. The pancreatic allograft exocrine secretion was drained into the proximal jejunum via a side-to-side duodenojujunostomy. Quadruple immunosuppressive regimen including induction of interleukin-2 receptor monoclonal antibody, tacrolimus, mycophenolate mofetil and steroid, and gradual tacrolimus monotherapy. The clinical data of the 9 patients were analyzed retrospectively. RESULTS AND CONCLUSION: SPK was successfully applied to all patients without serious surgical complications such as pancreatitis, graft dysfunction and pancreatic fistula. One patient died of cardiovascular accident in the early stage after SPK. The other 8 patients were followed up for 4-50 months. Serum creatinine decreased to normal range within 1 week after surgery. The 8 patients achieved euglycemia during early postoperative stage with insulin independence time (11.5±3.5) days and with fasting blood glucose recovery time (15.4±6.3) days. Acute rejection of the renal graft occurred in 4 patients, 1 patient died of cardiovascular accident and the other 3 recovered after antihuman thymocyte globulin or steroids bolus treatment. No rejection was noted in pancreatic grafts. These findings indicate that SPK is an effective treatment for patients with diabetes mellitus-related middle- and end-stage uremia.Quadruple immunosuppressive regime including interleukin-2 receptor monoclonal antibody induction is feasible after SPK, and such a regimen can be safely converted to tacrolimus monotherapy.
