Objective To review our experiences of diagnostic methods and surgical treatment of the left superior vena cava (LSVC) draining into the left atrium.Methods Nineteen patients with LSVC draining into the left atrium were diagnosed and treated surgically from February 1998 to January 2012.All the cases were combined with other congenital heart diseases including patent ductus arteriosus,ventricular septal defect,atrial septal defect,single atrium,triatriatum,partial endocardial cushion defect,anomalous pulmonary venous drainage,right ventricle outflow stenosis,pulmonary valve stenosis,tetralogy of Fallot,double outlet right ventricle,complete endocardial cushion defect,tricuspid atresia.The patients were diagnosed through different methods including echocartiographic examination,cardiac catheterization,computer tomography,and explored during the operation,even postoperatively.All were treated surgically with four techniques including simple ligation to the LSVC,including ligation during a redo procedure; intra atrial rerouting to drainage the flow from the LSVC to the right atrium,atrial septum reconstruction to make the outlet of the LSVC lying in the right side of the patched atrial septal,and bidirectional Glenn shunt to get a physiological result.Results No mortality postoperatively.All the cases were uneventful postoperatively.And the main postoperative course was related only to the main diagnosis of congenital heart disease,not to the left superior vena cava draining into the left atrium.The echo examination result was satisfied before the discharge.The early and long term follow-up(1-11 years) results are excellent,no arrhythmia,no cardiac deficits after echo examination,including stenosis obstruction and residual shunt.No death.Conclusion The diagnostic methods of the LSVC draining into the left atrium are difficult,the only way to make the diagnosis clearly enough before the operation is depending on improving of more and more comprehending to this rare cardiac anomaly,by the pediatric cardiologists,the sinologist,the intensive care unit,and the pediatric cardiae surgeons.The choice of different surgical treatment is depending on the diagnosis and the findings during the operations,and the results are excellent after a suitable choice made.

Objective To determine the effect and safety of metallic stents in the treatment of acute malignant colorectal obstruction.Methods From May,2000 to June,2003, self-expanding metallic stents were implanted in 15 patients with acute left colonic obstruction caused by malignancies. The postoperative remission and complications were observed.Results Stents were implanted successfully in 12 cases(80.0%,12/15).Of the 12 cases,the obstruction were all disappeared within 24h. No death or colonic perforation happened in this series. Stent migration and anal pain developed each in one case after stent implantation. Elective radical resection was performed on 8 cases after bowel preparation and supportive therapy; and stents reserved permanently in other 4 cases. Conclusions The implantation of self-expanding metallic stents is a safe and effective method for the temporary remission or permanent treatment of acute left-colonic or rectal obstruction caused by malignancies,it can instead of colostomy.

Objective To investigate the risk factors and establish the Cox's regression model and the personal prognosis index for the recurrence of ischemic stroke in 3-year follow-up.methods 1058 patients were retrospectively reviewed consecutively diagnosed with ischemic stroke admitted to the Neurology Department of the Hebei united University Affiliated Hospital from January 1,2013 to December 31,2013.Cases were followed up since the onset of ischemic stroke.The follow-up was finished in January 1,2016.Kaplan-Meier methods were used for recurrence rate description.Monovariant and multivariate Cox's proportional hazard regression model were used to analyze risk factors associated with recurrence.Thus,a recurrence model was set up.Result sDuring the period of follow-up,184 cases relapsed.The 1-year recurrence rate was 29.9 person-year,2-year recurrence rate was 46.6 person-year,3-year recurrence rate was 52.7 person-year.Monovariant and multivariant Cox's proportional hazard regression model showed that the independent risk factors associated with recurrence were age(X1)(RR=1.303;95%CI:1.019~1.666)history of heart disease(X2)(RR=1.788;95%CI:1.127~2.836),hypertension(X3)(RR=1.897;95%CI:1.097~3.280),diabetes(X4)(RR=1.674;95%CI:1.015~2.760),total cholesterol(X5)(RR=2.136;95%CI:1.396~3.266).The personal prognosis index(PI)of recurrence model was as the following: PI=0.265X1+0.581X2+0.640X3+0.515X4+0.759X5.Conclusion sAge,history of heart disease,hypertension,disease progression,and total cholesterol are the independent risk factors associated with recurrence of ischemic stroke.The recurrence model and the personal prognosis index equation are successful constructed.

Objective To investigate the utilization rate of gold fiducial markers and reasons for abandonment of gold fiducial markers in the CyberKnife VSI System, and to provide reference data for implantation of gold fiducial markers and radiotherapy planning. Methods From March to August,2017,a total of 47 patients had gold fiducial markers implanted or pasted. In those patients, 42 patients had gold fiducial markers implanted,including 32 receiving computed tomography(CT)-guided 3D-printing coplanar template assisted implantation, 1 receiving CT-guided 3D-printing non-coplanar template assisted implantation,1 receiving CT-guided implantation,and 8 receiving ultrasound-guided implantation. A total of 44 patients received the CyberKnife treatment, including 2 patients who failed to use gold fiducial markers and were treated with spine tracking instead and 3 patients missing the treatment for other reasons. The numbers of utilized and abandoned gold fiducial markers were recorded for calculation of the utilization and abandonment rates. The reasons for abandonment of gold fiducial markers were analyzed and classified. Results A total of 134 gold fiducial markers were implanted into or pasted to the 44 patients.In all the gold fiducial markers, 111 were utilized and 23 abandoned, yielding a utilization rate of 82.8% and an abandonment rate of 17.2%.The reasons for abandonment of gold fiducial markers included large rigidity error(26.1%), unqualified implanted fold fiducial markers(17.4%), displacement of gold fiducial markers(26.1%), and others(30.4%). Conclusions Compared with the CT-guided or ultrasound-guided implantation of gold fiducial markers, the CT-guided 3D-printing coplanar or non-coplanar template assisted implantation of gold fiducial markers requires only two puncture needles for each implantation and implants two gold fiducial markers by a single needle,which reduces the number of puncture needles,risk of puncture-induced injury,and incidence of complications after implantation. Not all the gold fiducial markers implanted by a variety of ways will be utilized. Some gold fiducial markers will be abandoned for different reasons,which should be taken into account during implantation of gold fiducial markers.

PURPOSE: To demonstrate the feasibility, safety, and technical strategies of hand-assisted laparoscopic complete mesocolic excision (HAL-CME) and to compare oncological outcomes between HAL-CME and the open approach (O-CME) for right colon cancers. METHODS: Patients who were scheduled to undergo a right hemicolectomy were divided into HAL-CME and O-CME groups. Measured outcomes included demographic variables, perioperative parameters, and follow-up data. Demographic variables included age, sex distribution, body mass index (BMI), American Society of Anesthesiologists (ASA) physical status classification, previous abdominal surgery, tumor localization, and potential comorbidities. Perioperative parameters included incision length, operative time, blood loss, conversion rate, postoperative pain score, postoperative first passage of flatus, duration of hospital stay, total cost, number of lymph nodes retrieved, TNM classification, and postoperative complications. Follow-up data included follow-up time, use of chemotherapy, local recurrence rate, distant metastasis rate, and short-term survival rate. RESULTS: In total, 150 patients (HAL-CME, 78; O-CME, 72) were included. The groups were similar in age, sex distribution, BMI, ASA classification, history of previous abdominal surgeries, tumor localization, and potential comorbidities. Patients in the HAL-CME group had shorter incision lengths, longer operative times, less operative blood loss, lower pain scores, earlier first passage of flatus, shorter hospital stay, higher total costs, similar numbers of lymph nodes retrieved, similar TNM classifications, and a comparable incidence of postoperative complications. The 2 groups were also similar in local recurrence rate, distant metastasis rate, and short-term survival rate. CONCLUSION: The results demonstrate that the HAL-CME procedure is a safe, valid, and feasible surgical method for right hemicolon cancers.

OBJECTIVETo summarize the initial experience of simultaneous pancreas kidney transplantation (SPK) with portal venous and enteric drainage.

METHODSBetween Jane 2001 and Jane 2003, SPK were performed in 5 patients. Systemic venous-enteric drainage (SED) was used in the first 2 patients and portal venous-enteric drainage (PED) in the last 3 cases. All patient were immunosuppressed with quadruple therapy, which included anti-CD25 mAb (Zenapax/Simulect) induction therapy, FK506, mycophenolate mofetil (MMF), and prednisone baseline therapy. The complications were analyzed.

RESULTSSerum glucose and renal function of the 5 cases were normal and no further insulin was needed within 7 days post-operation. No technique complications such as duodenal fistula and thrombosis were observed, One episode of acute rejection of kidney allograft occurred in one patient with SED, and resolved with a bolus corticosteroids. One case with SED and one with PED were died of sepsis and FK506 toxicity 4 weeks after transplantation. The death occurred with functioning pancreas graft. No latter complications were observed in the 3 survived patients with excellent graft functions.

CONCLUSIONSBoth methods of SED and PED can be performed successfully and with no latter complications. But with its potential physiologic and immunologic advantages, PED might be a standard procedure for SPK.

BACKGROUNDReceptor activator of nuclear factor kappa B (NF-κB) ligand (RANKL) and osteoprotegerin (OPG) have been recently shown to play important roles in bone resorption. The aim of this study was to investigate the possible association between the expression of bone resorption regulators (RANKL and OPG) and inflammatory cell infiltration in chronic apical periodontitis.

METHODSThe samples of chronic periapical lesions (n = 40) and healthy periapical tissues (n = 10) were examined for immunohistochemical analysis of RANKL and OPG. Lesion samples were further analyzed for the inflammatory infiltration condition. The inflammatory cell infiltration was scored in relation to immunohistochemical reactivity for CD3, CD20 and CD68.

RESULTSThe number of RANKL-positive cells and the ratio of RANKL/OPG in chronic apical periodontitis were significantly higher than those in healthy periapical tissues (P < 0.001). The number of RANKL-positive cells was higher in lesions with severe inflammatory infiltration than in those with light inflammatory infiltration (P < 0.05). Significantly increased RANKL expression was found with T lymphocytes (CD3(+)), macrophages (CD68(+)) and B lymphocytes (CD20(+)) infiltration (P < 0.05). No association was found between the ratio of RANKL/OPG and inflammatory cell infiltration.

CONCLUSIONSRANKL expression was increased with T, B lymphocytes and macrophages infiltration, respectively in chronic periapical lesions. RANKL appears to be closely related to periapical inflammatory infiltrates. The relative ratio of RANKL/OPG may be a key determinant of RANKL-mediated bone resorption.

OBJECTIVETo evaluate wound healing after types of pancreaticojejunostomy.

METHODSAfter resection of the pancreatic head, 38 domestic piglets were divided into two groups according to the types of anastomoses: group I: binding pancreaticojejunostomy, a new technique designed and advocated by professor Peng Shuyou; group II: end-to-end pancreaticojejunal invagination. Anastomotic strength in vivo and histopathological findings were assessed on operative day and postoperative day 5 and 10.

RESULTSBursting pressure was 139.7 +/- 8.0, 178.7 +/- 9.7 and 268.8 +/- 12.8 mm Hg in group I on day 0, 5 and 10, whereas 67.3 +/- 7.9, 96.2 +/- 10.4 and 130.6 +/- 9.3 mm Hg in group II. The gain on day 0 to 5 and 5 to 10 was 27.9% and 50.5% in group I and 42.9% and 35.7% in group II, respectively. A significant difference was observed between group I and group II, and between 5 and 10 day after anastomoses (P < 0.01). Breaking strength was 4.5 +/- 0.4, 6.6 +/- 0.4 and 10.0 +/- 0.6 N in group I on day 0, 5 and 10 and 4.6 +/- 0.6, 5.8 +/- 0.5 and 7.1 +/- 0.6 N in group II. Although a similar value was shown in both types of anastomoses on day 0, a rapider gain was demonstrated on day 0 to 5 and 5 to 10 in group I (44.8% and 52.9%) than in group II (25.4% and 22.0%). A significant difference was found on day 5 and 10 between the two types of anastomoses (P < 0.05 and P < 0.01). Anastomotic site was well repaired by connective tissue and the cut surface of pancreatic stump was covered by mucosal epithelium in group I on day 10, but the cut surface was incompletely repaired by granulation tissue and no, regeneration of the epithelium was found in group II.

CONCLUSIONAnastomotic strength of binding pancreaticojejunostomy was stronger than end-to-end pancreaticojejunal invagination and the healing was better and rapid.
