Objective To investigate the expression and distribution of parathyroid hormone (PTH) in renal tissues of early stage chronic kidney disease (CKD),and to elucidate its potential role in renal lesion.Methods Eighty-two patients of early stage CKD (stage 1 and 2) diagnosed as glomerulonephritis (GN) with different pathologic types by renal biopsy in our department between 2009 and 2012 were enrolled in the study.Renal tissues of eight patients with mismatched HLA haplotype or the normal part of renal cancer were chosen as controls.Scr,BUN,serum calcium,phosphorus,PTH and 25(OH)VitD3 were measured.Creatinine clearance (Ccr) was calculated by Cockcroft-Gault (CG)formula.99mTc-DTPA clearance rate was used to detect GFR.Patients were divided into mild,moderate and severe groups according to the renal interstitial extent of inflammatory cells infiltration.Immunohistochemistry was used to observe the expression and distribution of PTH in renal tissues.Image-Pro Plus software was used to calculate A value of PTH in renal tissues and compare the extent of PTH expression.Results The levels of calcium,phosphorus,25(OH)VitD3 and PTH in peripheral blood from GN patients of CKD stage Ⅰ and 2 were normal.PTH had no correlation with the above indexes.PTH expression could be seen in renal tissues of all the GN patients with different pathologic types,and it mainly located in renal tubular,only a few in glomeruli and interstitium.The expression of PTH in renal tissues of GN increased compared with the controls (P ＜ 0.01).Furthermore,PTH expression elevated with the increase of inflammatory cells infiltration in interstitium.However the expression of PTH was not significantly different among different pathologic types of GN.Conclusions In the early stage CKD,PTH expression in patients of GN increases,which occurs earlier as compared to PTH elevation in peripheral blood and the imbalance of minerals and bone metabolism.The intensity of PTH expression is associated with the local inflammation.

Objective To investigate the ability of social cognition in patients with right temporal lobe infarction.Methods Fifteen patients with temporal lobe infarction (TLI) and 20 healthy controls (HC) were examined with the recognition of faux pas and reading the mind in the eyes tasks for assessing the ability of social cognition.Results The TLI group performed significantly worse when compared with the HC group (28.6 ± 6.1,36.4 ± 4.3 respectively) as revealed in the total faux pas-related scores (U =41.00,P ＜0.01).For the control question,there was no significant difference between the TLI group and the HC group (9.86 ±0.35,10.00 ± 0.00 ; U =130.00,P =0.097).In the reading the mind in the eyes task,patients with TLI performed worse than the HC group(17.13 ±6.41,29.75 ±2.07 respectively),and the difference had statistical significance (U =0.00,P ＜ 0.01).But there was no significant difference in gender recognition judgment (30.37 ± 1.16,31.35 ± 1.08 respectively; U =106.00,P =0.129).Conclusions The right temporal lobe involves in social cognition.Moreover,the right temporal lobe not only involves in the verbal related social cognitive processing,but also involves in the no-verbal related social cognitive processing.

Objective To investigate the values of three-dimensional visualization technology in the diagnosis and surgical treatment of hepatic hemangioma. Methods Thirty two patients with hepatic hemangioma who had been hospitalized during the period from July 2010 to January 2014 in our hospital were scanned by 64-slice spiral computerized tomography (CT) before surgical treatment. Three-dimensional (3D) reconstruction based on the CT data was carried out to achieve dignosis and surgical planning. Assisted with the 3D model , we chose the best surgical procedure for liver resection, protecting the major blood vessels near hemangioma and retaining normal liver tissue as far as possible. Results The location, size and shape of hepatic hemangioma, vascular variation, and spatial relationship with intrahepatic vessel were shown factually by three-dimensional reconstruction. All the hemangiomas were preoperatively assessed to be resectable. The compliance rate for preoperative surgical planning to actual surgery was 100%. Under assistance of the 3D model during surgery , 14 patients received laparoscopic hepatectomy and 18 underwent hepatectomy. Pringle′s maneuver was applied in 18 patients , with blocking time of (15.32 ± 7.12) min and blood loss of (188.63 ± 66.37) mL. The postoperative complications included pleural effusion in 5 patients and incision infection in one patients. Conclusions Three-dimensional visualization technology for the individualized diagnosis and treatment of hepatic hemangioma helps reduce surgical trauma and incidence of postoperative complications.

OBJECTIVESTo further investigate the effects of cisapride on intestinal bacterial overgrowth (IBO), bacterial and endotoxin translocation, intestinal transit and permeability in cirrhotic rats.

METHODS25 normal control rats, 25 cirrhotic rats, 20 cirrhotic rats received saline, and 20 cirrhotic rats treated with cisapride were included in the study. All animals were assessed with many variables including bacterial and endotoxin translocation, IBO, intestinal transit and permeability.

RESULTSBacterial translocation was found in 48%(12/25) cirrhotic rats and none of control rats. Among the 20 rats with IBO, there were 11 rats with bacterial translocation (BT) while only one rats occurred BT out of the 5 rats without IBO. Cirrhotic rats with IBO had a significantly higher rate of endotoxin translocation, higher intestinal permeability and longer intestinal transit than those without IBO. BT of a specific organism was always associated with IBO of that organism. Compared with the placebo group, cisapride-treated rats had lower rates of bacterial and endotoxin translocation and IBO, which had close relationship with shorter intestinal transit and lower permeability.

CONCLUSIONEndotoxin and bacterial translocation in cirrhotic rats may be the result of IBO and higher permeability. IBO may be the result of longer transit. Cisapride which can accelerate intestinal transit and improve intestinal permeability is helpful in preventing and treating intestinal bacterial and endotoxin translocation.

OBJECTIVETo investigate whether cyclooxygenase-2 (COX-2) and heme oxygenase-1 (HO-1) are involved in the bradykinin-induced delayed protection.

METHODSCardiac contractility, lactate dehydrogenase (LDH) and infarct area were analyzed in isolated rat hearts undergoing ischemia-reperfusion injury induced by Langendorff method.

RESULTConscious rats received bradykinin (40 microg/kg), and the isolated hearts were subjected to 30 min of regional ischemia and 120 min of reperfusion 24 h later. Bradykinin pretreatment would improve post-ischemic performance, and reduced the release of LDH and infarct size. COX-2 inhibitor celecoxib (3 mg/kg) abolished bradykinin-induced protection, leading to poorer myocardial performance, release of more LDH and larger infarct sizes. Administration of HO-1 inhibitor ZnPP IX(20 microg/kg) before bradykinin partially abrogated the delayed protection. Pretreatment with the mitochondrial ATP sensitive potassium channel(mitoK(ATP) antagonist 5-HD before or 24 h after bradykinin administration also abolished the effect of protection.

CONCLUSIONThe results indicate that activation of HO-1 and COX-2 might be involved in the delayed cardioprotection evoked by bradykinin, and mitoK(ATP) channel may serve as both a trigger and a mediator in the cardioprotection.

Objective: To investigate the efficacy of alternative donor (AD) in the treatment of aplastic anemia (AA) in children. Methods: The clinical data of AA children who received AD HSCT in our center from Apr. 2010 to Dec. 2016 were retrospectively analyzed. The overall survival (OS) rate, implant success rate, incidence of acute and chronic graft-versus-host disease (GVHD) were statistically analyzed. Results: A total of 109 children with acquired AA, including 64 severe AA (SAA) , 32 very severe AA (VSAA) and 13 transfusion dependent non-severe AA (NSAA) , were recruited in this retrospective AD HSCT study, the median age was 6 (0.8-18) years old. Of them, 44 patients with 10/10 matched unrelated donor (MUD) , 44 patients with mismatched unrelated donor (MMUD) and 21 patients with mismatched related donor (MMRD) . All patients did not receive ATG before HSCT and the active infection was excluded. Except 3 patients suffered from a second graft failure (2 of them rescued by second HSCT) , 106/109 (97.2%) were engrafted with neutrophil and platelet recovery occurring at a median of 13 days (range, 9-19) and 16 days (range, 10-81) post-transplant. Until day 100 post transplantation, the incidence was 74.3% (81/109) for acute GVHD (aGVHD) and 39.4% (43/109) for grade Ⅱ-Ⅳ aGVHD, 30.7% (31/101) and 9.9% (10/101) for overall chronic GVHD (cGVHD) and moderate cGVHD, respectively, and nobody developed an extend cGVHD. After median follow up of 39 (0.7-103) months for all patients, 13 of 109 patients died. The estimated 5-year overall survival (OS) of the entire cohort was 88.1% (95%CI 81.1%-91.4%) with no difference among the MUD, MMUD and MMRD cohort (93.2%, 84.1% and 85.7%, respectively, P=0.361) . Conclusion: These excellent outcomes suggest that unmanipulated AD PBSC is a good HSCT source for children with SAA. It's reasonable to consider AD HSCT as first line therapy for SAA children without matched sibling donor. Better strategies are required to prevent GVHD.
