Objective To investigate the relation between serum asymmetric dimethylarginine (ADMA) level and endothelial function before and after living donor kidney transplantation in uremic patients.Methods A total of 38 renal transplant patients (21males and 17 females) and 36 healthy controls (20 males and 16 females) were enrolled. Plasma ADMA, symmetric dimethylarginine (SDMA), malondialdehyde (MDA), glutathione peroxidase (SeGSHPx), C-reactive protein (CRP) were mea-sured before transplantation and on Days 1, 3, 7, 14, and 28 posttransplantation. The brachial artery flow mediated dilatation (FMD) was studied before transplantation and on the 28th day after the transplantation. Results Serum levels of ADMA,SDMA,MDA and CRP were significantly increased, and the activities of nitric oxide (NO) and SeGSHPx were decreased in uremic patients compared with age matched healthy subjects (all P＜0.01). Serum levels of ADMA,SDMA,MDA and CRP decreased while the activities of NO and SeGSHPx increased significantly at the first day after the transplantation (all P＜0.01). The decrement of plasma SDMA normalized on the 28th day (P＞0.05). The FMD was lower in the patients than the control group (P＜0.01) and improved significantly on the 28th day of posttransplantation (P＜0.05). Serum levels of ADMA were positively correlated with MDA (r=0.412, P＜0.01;r=0.342,P＜0.01) and negatively correlated with the values of SeGSHPx (r=-0.345, P＜0.01;r=-0.315, P＜0.01) and FMD (r=-0.452,P＜0.01;r=-0.416,P＜0.01) both before and after kidney transplantation. Conclusion The level of serum ADMA is associated with endothelial function improvement in uremic patients both before and after kidney transplantation.

Objective To observe the effect of constraint-induced movement therapy combined with motor imagery on unilateral spatial neglect (USN) in stroke patients. Methods Fifty stroke patients with USN were randomly divided into a treatment group ( n = 27 ) and a control group ( n = 23 ). Both groups received routine physical therapy training, including with the Bobath technique and low frequency electrotherapy, while the treatment group received constraint-induced movement therapy and motor imagery in addition. All the patients were assessed with 4 scales of the regular USN assessment ( cancellation tests, line bisection tests, clock drawing tests,copying drawing tests) and with the Barthel index (BI) before and after 8 weeks of treatment. Results After 8 weeks of treatment, both groups' average USN assessments and Barthel indices improved significantly. Furthermore, both the USN results and the Barthel index scores in the treatment group were, on average, significantly better than those in the control group. Conclusion For USN stroke patients, constraint-induced movement therapy combined with motor imagery improves the symptoms of USN and ADL ability significantly better than routine physical therapy treatment alone.

Objective To study CT and MRI features of intracranial chondrosarcomas. Methods CT and MRI of 3 cases with intracranial chondros arcomas proved by pathology were retrospectively analyzed.Results CT scans showed the tumors were lobular mass, per itumoral edema were not serious, intratumorous calcification and bone invasion w ere seen in 2 cases.MRI showed that tumor had low to intermediate signal intensi ty or hypointensity on T 1WI, high signal intensity on T 2WI. On contrast enha nced MRI,the center of lesions which was low signal intensity on T 2WI was no e nhancement, but there was observable enhancement at periphery of tumors.Conclusion Intracranical chondrosarcomas are often orgina ted from synchondrosis of the skull base,the lesions are often associated with c alcification, and bone invasion, the accurate dignosis should depend on microsco pic examination and immunohistochemical staining.

Objective To study the appearance of magnetic resonance imaging (MRI) in early stages of cartilage degeneration and to detect its values.Methods Intra articular injection of 5 units of papain causing a reversible loss of cartilage proteoglycan in the New Zealand rabbit knees.Rabbits were scanned with magnetic resonance imaging,using a 0 3 T Hitachi magnet with 16 cm coil.Gradient echo sequences and spin echo sequences were performed in the sagittal planes at 0,24,48 and 72 hours after intra injection of papain.Then signal intensity and thickness of cartilage were measured.The proteoglycan content was measured biochemically and histochemically.Results The cartilage thickness and signal intensity decreased significantly in treated knees compared with control knees at 24 and 48 hours ( P 0 05) after injection of papain.These changes on magenetic resonance (MR) images were consistent with the changes of proteoglycan concentration measured by biochemical analysis and histochemical staining of cartilage.Conclusion It is possible for MRI to detect the early stages of cartilage degeneration.

Objective To examine the effect of fibronectin connecting segment-1 (CS1) peptidefacilitated blockade of inflammatory cells-fibronectin adhesion on a rat liver transplantation model of prolonged ex vivo cold ischemia.Methods A model of liver transplantation in Wistar→Wistar rat was established.The donors of the CS1 treatment group received CS1 peptides through the tail vein for 3 days before operation.Another two doses of CS1 peptides were administered into the liver intraportally during procurement and before transplantion.Recipients received an additional 3-day course of CS1 peptides after transplantation.Rats in control group received scrambled peptides.Rats were sacrificed at 6,24 and 72 h after transplantion,and plasma transaminase activity and hepatic pathological changes were studied.The inflammatory cells and liver sinusoidal endothelial cells were visualized histochemically.Real-time PCR was used to detect tumor necrosis factor-α (TNF-α),interleukin-1β (IL-1β) and vascular endothelial growth factor (VEGF) mRNA expression in the liver.Results The plasma transaminase activity and hepatic necrosis areas in CS1 treatment group were significantly lower than in control group (P＜0.05).CS1 peptides treatment significantly decreased the number of Kupffer cells after transplantation and greatly inhibited the recruitment of neutrophils to the graft liver as compared with control group (P＜0.05).After prolonged cold ischemia,only a few hepatic endothelial cells exhibited positive staining of hepatic sinusoidal endothelial cell biomarker SE-1.Lots of hepatic sinusoidal endothelial cells positive for SE-1 staining could be detected in CS1 group at 72 h after transplantation,while much less SE-1 positive cells presented in the control goup.Prolonged cold ischemia caused a significant increase of TNF-α,IL-1β and VEGF mRNA expression in the graft liver of control group after transplantation.The expression of TNF-α mRNA at 6 and 24 h and VEGF mRNA expression at 24 h were significantly lower in CS1 group than in control group (P＜0.05).Conclusion Peptide-mediated blockade of inflammatory cells-fibronectin interaction decreased the mRNA expression of inflammatory cytokines,prevented hepatic sinusoidal endothelial cells from injury and subsequently protected against severe ischemia/reperfusion injury of the graft liver after transplantation.

Objective To investigate the effects of multimodal analgesia of parecoxib and fentanyl on perioperative immune functions in patients of hepatocellular carcinoma (HCC).Methods Eighty HCC patients scheduled for hepatectomy were randomly divided into two groups:parecoxib sodium combined with fentanyl group (group P,40 cases) and fentanyl group (group C,40 cases).The percentages of CD3 +,CD4+,CD8+,CD4+/CD8+ T cells,CD3-CD16+ CD56+ (NK),interleukin-4 (IL-4),interferon-γ (IFN-γ) and the ratio of IFN-γ/IL-4 were detected at the following time points:30 minutes before induction of anesthesia (T0),at the end of the surgery (T1),24 h after surgery (T2) and 72 h after surgery (T3).The analgesic effects were estimated by visual analogue scale (VAS) after surgery.Total fentanyl consumption and adverse effects were also recorded.Results The percentages of CD3 + T cells were significantly lower in group C than that in group P at T2 (t =2.155,P ＜0.05).The percentages of NK in group P were recovered nearly to baseline (T0) at T2,which was higher than that of group C (t =2.791,P ＜0.05).In group C,the percentages of CD3 + T cells and NK has not recovered to baseline at T3 (respectively t =3.065,3.231,P ＜ 0.05).In group P,IL-4 serum levels were significantly lower than those in group C,while IFN-γ serum levels were significantly higher than those in group C at T2 (respectively t =2.173,2.100,P ＜0.05).From T2 to T3,the ratio of IFN-γ/IL-4 significantly increased in group P than those in group C (respectively t =3.259,2.203,P ＜ 0.05).VAS scores at rest and on cough in group P were significantly lower than those in group C at 2 h,6 h,12 h and 24 h after operation (respectively t =8.661,9.726,9.147,7.109,P＜0.05;t =8.569,9.614,9.144,8.509,P＜0.05).The total fentanyl consumption in group P was lower than that in group C (t =2.636,P ＜ 0.05).There were no significant differences regarding the incidence of adverse effects between the two groups.Conclusions Perioperative multimodal analgesia of parecoxib sodium combined with fentanyl enhances the analgesic efficacy,and reduces the dosage of opioid consumption,helps recover the cell immunity function of HCC patients after hepatectomy.

OBJECTIVE: To investigate the relationship between the level of Foxp3 mRNA in the peripheral blood monocytes (PBMCs) with acute rejection or chronic allograft nephropathy after kidney allotransplantation. METHODS: Real-time quantitative polymerase chain reaction was used to examine Foxp3 mRNA expression in the PBMCs from 16 patients with acute rejection, 8 patients with chronic allograft nephropathy, 8 patients at stable stage after kidney transplantation, 8 patients of end-stage renal disease, and 8 normal controls. RESULTS: The level of Foxp3 mRNA in the PBMCs was significantly lower in patients with acute rejection than that in patients with chronic allograft nephropathy (P<0.01). Foxp3 mRNA expression was significantly lower in patients with chronic allograft nephropathy than that in the normal controls, the end-stage renal disease group, and stable stage group (P<0.01). The level of Foxp3 mRNA was not significantly different in the PBMCs among the normal controls, the end-stage renal disease group, and the stable stage group (P>0.05). CONCLUSION The level of Foxp3 mRNA expressed in PBMCs can reflect the status of renal allograft, and may be a noninvasive biomarker for diagnosing acute rejection and chronic allograft nephropathy.
