Objective To observe the efficacy of growth hormone ( GH) co-treatment in poor responders undergoing IVF-ET.Methods To analyze all the ovaries low response patients treated by IVF/ICSI,80 cases were ran-domly divided into two groups:40 patients in GH group were given GH along with Gn daily until the HCG administra-tion.40 patients in the control group received the same treatment protocol except the GH co -treatment.The catching spawn number and MⅡova,fertile rate,the number of perfect embryos ,pregnant rate were observed .The serum con-centrations of IGF-I,IGFBP-3 were detected by ELISA and compared between the two groups .Results The number of oocytes retrieved ,number of MII oocytes ,cleavage ,number of embryos available of GH group were increased without statistical significance(all P>0.05 ).The serum IGFBP-3 level of 2 groups had no statistical significance .The fertile rate,pregnant rate ,serum IGF-I level were significantly higher in GH group than those in the control group ( all P<0.05).Conclusion GH co-treatment in poor responders could improve the outcome of IVF-ET,which imply that GH could improve the quality of oocytes and embryos related to the elevated IGF-1 level in serum .

Thoracic endovascular aortic repair (TEVAR) has been increasingly used in the treatment of Stanford type B dissection.The incidence of new entry after thoracic endovascular aortic repair has been gradually increased report including at the proximal end and at the distal end of the endograft.New entry is difficult to handle following thoracic endovascular aortic repair for aortic dissection,and associates with a high substantial mortality.It need pay more attention to prevention and treatment on new entry after thoracic endovascular aortic repair.We summary and analyze the possible causes,prevention and management of new entry after thoracic endovascular aortic repair for aortic dissection.This article review and conclusion the progress on stent graft induced new entry after thoracic endovascular aortic repair.

Objective To explore the distribution characteristics and clinical typing methods in distal crevasses of Stanford B aortic dissection.Methods Review of the cases in the People's Hospital of Xinjiang Urgur Autonomous Region from 2010 January to 2013 June were diagnosis of Stanford type B aortic dissection with computed tomographic angiography data,Observed its distal crevasses distribution and statistical its number,then summarizes the distribution characteristics of the distal crevasses and further put forward a method of clinical typing.Results Refer to 115 cases with Stanford type B aortic dissection computed tomographic angiography data,including 101 cases with distal crevasses (87.83％) and a total of 240 distal crevasses,an average of 2.37 per case.Conclusions The distal crevasses more often appear in the area involving visceral artery,combined with its different in distribution characteristics and processing methods,we put forward the classification method,namely:Type Ⅰ:the distal crevasses are located in the zone of the thoracic artery; Type Ⅱ:the distal crevasses are close to the visceral artery or involvement it; Type Ⅲ:the distal crevasses are lower than the renal artery,not involving the visceral artery; Type Ⅳ:the distal crevasses are located in the zone of the iliac artery.

Objective To explore the significance and important measure of integrative treatment of multiple trauma patients with severe craniocerebral injury in emergency center. Methods One hundred and forty-eight multiple trauma patients with severe craniocerebral injury in emergency center from November 2002 to February 2006 were analysed retrospectively. Result In total 148 cases, 72 were cured and 26 dead, 7 were in status of plant man, 17 experienced severe deformity, and 26 did mild deformity. Conclusion Multiple trauma patients with severe craniocerebral injury usually experience a serious situation and rapid development. Therefore emergency doctors are required for organizing salvage of such patients, at the same time treatment and diagnosis are implemented. Firstly the most important key to successful salvage is appropriate disposal of fatal injury and early elimination of shock. Proper surgical choice, especially at the first time, inspection and protection of visceral functions, and attention to nutritional support are other vital methods to gain more successful salvage. ICU is also emphasized for its essentiality.

Objective To evaluate the perioperative safety of minimally invasive and open pancreaticoduodenectomy (PD).Methods The China National Knowledge Infrastructure,VIP,PubMed,The Cochrane Library and EMBASE were searched with the key words of laparoscopic,laparoscopy,robotic,da Vinci,minimally invasive,pancreaticoduodenectomy,微创,腹腔境,机器人,胰十二指肠切除术 to retrieve literatures on minimally invasive and open pancreaticoduodenectomy.All the patients were divided into the minimally invasive PD group and the open PD group,and the patients in the minimally invasive PD group were further divided into the robotic PD group and the laparoscopic PD group.A meta analysis was carried out using the RevMan 5.2 software.The count data were represented by the odds ratio (OR) and 95％ confidence interval (95％ CI),and the measurement data were represented by the weighted mean difference (WMD) and 95 ％ CI.Heterogeneity of the publication was analyzed using chi-square test,and the publication bias was analyzed using the funnel plots.The stability of results was analyzed using the sensitivity analysis.Results Ten literatures including 690 patients were selected.There were 235 patients in the minimally invasive PD group,and 455 in the open PD group; 107 patients were in the robotic PD group and 128 in the laparoscopic PD group.There were no significant difference in the incidence of postoperative complications,pancreatic fistula,delayed gastric emptying,postoperative hemorrhage,bile leakage,reoperation,mortality and number of lymph nodes dissected between the minimally invasive PD group and the open PD group (OR =0.75,1.01,0.98,1.50,0.94,0.56,1.06,WMD =2.29,95％ CI:0.40-1.41,0.67-1.53,0.55-1.77,0.76-2.94,0.37-2.38,0.26-1.20,0.48-2.32,-0.55-5.13,P ＞ 0.05).Although the operation time of the minimally invasive PD group was significantly longer than the open PD group,lesser volume of blood loss,shorter duration of postoperative hospital stay and higher R0 resection rate was detected in the minimally invasive PD group (WMD =99.57,-355.70,-3.30,OR =0.49,95％ CI:36.99-162.15,-608.38--103.01,-6.58-0.03,0.26-0.92,P ＜ 0.05).The operation time of the laparoscopic PD group was significantly longer than that of the open PD group (WMD =93.17,95％ CI:55.98-130.37,P ＜ 0.05).The operation time of the robotic PD group was comparable to that of the open PD group (WMD =122.96,95％ CI:-48.48-294.40,P ＞ 0.05).There was no significant difference in the duration of postoperative hospital stay between the laparoscopic PD group and the open PD group (WMD =-0.81,95％ CI:-5.08-3.45,P ＞ 0.05).The operation time of the robotic PD group was significantly shorter than that of the open PD group (WMD=-6.82,95％CI:-13.21--0.44,P＜0.05).Conclusions The perioperative safety of minimally invasive PD was comparable to open PD.Minimally invasive PD has the advantages of lesser blood loss and quick recovery of patients.Robotic PD could significantly decrease the operation time.Minimally invasive PD could be a reasonable alternative when the requirement of indications is fulfilled.

Objective To explore the misunderstanding and comprehension of hybrid operation for treating aortic dissection involving aortic arch.Methods From March 2009 to November 2013,13 patients received hybrid operation for aortic dissection involving aortic arch in the People's Hospital of Xinjiang Urgur Autonomous Region were enrolled,including male 11 and female 2,and aged 36 ～ 60 years old with a mean age (44 ± 6.8) years old.All patients were type-B aortic dissection.All of them were not suitable to be treated with endovascular exclusion monotherapy.The ascending aorta-brachiocephalic artery bypass and left carotid artery bypass was established with median sternotomy approach and neck incision in 13 patients,and 2 patients did left subclavian artery bypass additionally,then retrograde endovascular stent graft implantation was used.Computed tomography angiography (CTA) scanning at 3-month,9-month,1-year and every-year after operation showed no stent grafts translocation and bypass graft obstruction.Results The surgical operation and stent grafts implantation were completely successful.Angiography showed 1 case had end leakage and other cases no obvious displacement or end leakage of stent grafts in operation.Blood flow in true lumen of aortic dissection was recovered and all of bypass grafts were unobstructed.No death and severe complications occurred.All patients were followed-up with 3 to 56 months [(29.0 ± 10.2) months],and all patients resumed normal life.Enhanced CT scanning after operation showed 1 case had endoleak and other cases no endoleak,stent grafts translocation and bypass graft obstmction.No signs of brain and limb ischemia were observed.Conclusions To summarize misunderstanding and experience by continuous explore feature of hybrid operation for treating disease involving aortic arch,we developed a more reasonable surgical treatment options that can improve the success rate of complex aortic dissection surgery,and ultimately achieve better surgical results.

Objective To assess the treatment of splenic artery aneurysms(SAA) and curative effect evaluation.Methods Twelve SAA patients treated in our hospital from January 2012 to May 2014 were clinical analyzed.The male in Twelve patients was 4 man and others were female.The vagus splenic artery aneurysms are originated from the superior mesenteric artery,tumors are single,from 1.5cm to 2.8cm in diameter,an average of 2.1cm.Twelve cases were performed surgery,4 patients underwent elective surgery,interventional embolization of the splenic aneurysm in 3 patient,The others were performed interventional embolization + superior mesenteric artery covered stents.Results Technical success was achieved in all twelve patients,2 patients had adverse effects such as abdominal pain,fever,etc.There revealed no aneurysm recurrence was found.Twelve patients were followed for 6-24 months,the follow-up by examinations with electronic computer X-ray tomography or color Doppler ultrasonic as well as angiography every 3 months.One patient died of severe abdominal bleeding 1 year later after the operation and the other eleven patients remained in good condition with no occurrence of re-canalization of the lesions.Conclusions For the vagus splenic aneurysm with suitable for anatornic conditions,cavity therapy is safe and effective,for the vagus splenic aneurysm involving hepatic artery,need to open surgery for vascular remodeling.

Objective To evaluate the efficacy and safety of catheter-directed thrombolysis (CDT) combined with anticoagulant compared with traditional treatment (Anticoagulant alone A C) for deep venous thrombosis.Methods We searched Medline,Embase,Cochrane Central Register of Controlled Trials,PubMed,Chinese Biomedical Literature Data Base (CBM),Chinese Scientific Journal,Full-text Data Base (CSJD),and,added with hand searcing and other retrievals.The Cochrane Collaboration's RevMan 5.0.18 was used for Meta-analysis.Results Four randomized controlled trials were available and were included in the study.Meta-analysis showed that 6 months after treatment,iliofemoral vein patency rate of CDT group was higher than that of AC group (OR =5.13,95％ CI:2.01-13.14,P =0.0006);Major complications of CDT group compared to those of AC group were not statistically significant(OR =2.74,95％ CI:0.76-8.07,P =0.13),but the minor complications and total complications of CDT group were higher than those of AC group [(OR =7.86,95％ CI:3.10-19.90,P ＜0.0001)and(OR=5.42,95％CI:1.47-20.01,P=0.01)].Conclusions CDT is a positively effective way to treat early DVT.Application of CDT in patients without contraindications to its use can have good therapeuic effect.
