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 explore the role of inflammatory reaction mediated by p38-mitogen activated protein kinase (p38-MAPK) signal path on prevention and treatment of Parkinson disease (PD) model rats by electroacupuncture (EA).
METHODSThirty-two healthy male SD rats were randomly divided into a normal group, a sham operation group, a model group and an EA group, eight rats in each one. The PD model was established in the model group and EA group by subcutaneous injection of rotenone in skin-back area (2 mg/kg, dissolved in sunflower oil, 2 mg/mL in density), while the injection of sunflower oil emulsion without rotenone at the same point and quantity as the model group was applied in the sham operation group. The normal group was not given any intervention. The EA treatment (continuous wave, 2 Hz in frequency, 1 mA in intensity, 20 min) was applied at "Fengfu" (GV 16) and "Taichong" (LR 3) in the EA group, once a day for continuously 14 days. No treatment was given in the other groups. The expression of tyrosine hydroxylase (TH), phosphorylated p38-MAPK, cyclooxygenase-2 (COX-2) in the substantia nigra were detected with immunohistochemical method.
RESULTSThere was typical PD ethology change in the model group. Compared with the normal group and sham operation group, the expression of TH positive neuron in the substantia nigra in the model group was significantly decreased, while the expression of phosphorylated p38-MAPK and COX-2 were significantly increased (all P < 0.01). Compared with the model group, the expression of TH positive neuron in the EA group was apparently increased, while the expression of phosphorylated p38-MAPK and COX-2 were significantly decreased (all P < 0.01).
CONCLUSIONThe EA therapy could obviously reduce the expression of inflammation mediator COX-2, inhibit the phosphorylation of p38-MAPK, reduce the damage of dopaminergic neurons in the rats with PD, and this effect may be related with the impact of p38-MAPK signal path
