Objective To investigate the relationship between the activity of Na +/K +pump on RBC membrane and abnormal potassium transportation through cellular membrane in hypokalemic patients Methods Activity of RBC ATPase in 17 cases of hypokalemic paralysis patients and 16 cases of healthy controls was tested Results Activity of RBC ATPase was statistically higher in hypokalemic periodic paralysis (HOPP)group[( 25 6?3 5) ?mol?(10 7RBC) 1 ?h 1 ], and lower in nephridium oxidosis group [(1 9?0 8) ?mol?(10 7RBC) 1 ?h 1 ]than in control group[(6 2?0 9) ?mol?(10 7 RBC) 1 ?h 1 , P

Objective To evaluate the actual mismatch risk for KIR genes,KIR ligand HLA-C gene and KIR ligand HLA-Bw4I80 related genes in kidney transplant recipients and their donors.Method KIR genes,KIR ligand HLA-C gene and KIR ligand HLA-Bw4I80 related genes were analyzed in 322 recipients and their donors who received kidney transplantation.The effect of mismatches on acute rejection after transplantation was studied as well.Result In 322 cases of recipients and their donors,average mismatch risk for KIR-L gene was 4.73％,9.10％ for KIR-S gene and 1.95％ for KIR ligand HLA-C gene respectively.There were 245 cases (76.09％) of KIR ligand HLA-Bw4I80 related genes mismatch and 77 cases (23.91 ％) of match resepctively.There was no statistically significant difference in AR rate between KIR ligand HLA-Bw4I80 related genes mismatch group and match group (8.16％ in 245 vs.7.79％ in 77) (P＞0.05).AR reversal rate in mismatch group and match group was 95.0％ and 66.7％ (P＞0.05).Conclusion The mismatch risk for KIR ligand HLA-Bw4I80 related genes was even common between kidney transplant recipients and their donors,and this specific mismatch may be of benefit to patients who undergo actuate rejection.Further study is still required.

Objective To determine the value of MR cholangiography(MRC)in the preoperative evaluation of biliary anatomy of living liver donors.Methods Fifty eight consecutive donors underwent MRC examinations and living liver transplantation.MRC was performed on a 1.5 T scanner with breath-hold rapid acquisition of T_2WI slab and breathing-gating 3D FSE T_2WI.Images of MRC and IOC were compared and classified according to the modified Huang's classification.Results Thity four(58.6%)liver donors showed normal biliary anatomy on IOC,and 24(41.4%)donors revealed variant bile anatomy.MRC correctly depicted biliary anatomy in 91.4%(53/58)donors.The sensitivity,specificity,positive predictive value and negative predictive value of MRC in distinguishing normal and difierent types of variant biliary anatomy were 83.3%(20/24),100%(34/34),100%(20/20),89.5%(34/38)respectively.Conclusion MRC can accurately assess the biliary anatomy in living liver donors and may guide the preoperative planning of liver transplant.

Diabetic nephropathy is one of the most serious complications of diabetes mellitus and it seriously endangers people's health.Some previous studies indicate that the occurrence and development of diabetic nephropathy is not positively associated with control of blood glucose and course of disease,Its development has family aggregation and ethnic differences.In addition to environmental factors,genetic factors play an important role in the process of occurrence and development of diabetic nephropathy,Many genetic mutations can lead to a high degree of susceptibility to diabetic nephropathy.Discovery of some related genes of diabetic nephropathy and elucidation of these genes function provide an effective means in the early diagnosis,gene therapy and individualized drug therapy of diabetic nephropathy.In this review the action and function of discovered related genes of diabetic nephropathy are summarized.

Objective To evaluate the value of virtual touch tissue imaging quantification (VTIQ),which was combined with ultrasound Breast Imaging Reporting and Data System (BI-RADS),for differentiating benign from malignant breast lesions.Methods Totally 190 patients with 214 breast lesions were enrolled in this study.All lesions were classified according to the BI-RADS for sonography.The maximum,minimum and mean shear wave velocity (SWV) values on VTIQ in the lesions were obtained.The SWV between benign and malignant lesions were analyzed.Receiver operating characteristic(ROC) curves were plotted to determine the cut off value of VTIQ for differential diagnosis of breast lesions. Results Pathology confirmed 166 benign lesions and 48 malignant lesions.The SWVmax,SWVmin,SWVmean of malignant lesions were significantly higher than those of benign lesions (all P<0.001).The SWVmean 3.67 m/s as the best value in the diagnosis of benign and malignant lesions.The sensitivity,specificity,positive predictive value and negative predictive value of the combination of the SWVmean and BI-RADS classification standard in the diagnosis of benign and malignant breast lesions were 77.6%,97.5%,92.7%,91.3%,respectively.Conclusions The combination of VTIQ and ultrasonic BI-RADS can improve the ability of differential diagnosis of benign and malignant breast lesions.

Objective To investigate the role of phosphatidylinositol 3-kinase (PI3K)/protein-serine-threonine kinases(Akt) signal transduction pathway in EphB receptor-mediated neuropathic pain in rats.Methods Forty-eight pathogen-free male SD rats aged 2-3 months weighing 150-180 g were randomly divided into 6 groups (n =8 each):groups sham operation (groups S1 and S2 ); groups chronic constrictive injury (CCI) (groups C1and C2 ) and groups EphBI-Fc (EphB receptor antagonist) + CCI (groups E1 and E2 ).Neuropathic pain was induced by placing 4 ligatures on left sciatic nerve at 1 mm intervals with 5-0 silk thread in groups C1,C2,E1 and E2.EphBI-Fc 0.5 μg in 5 μl normal saline was injected intrathecally 1 h before operation and at 1 and 2 d after operation (group E1 ) or on 5th day after operation (group E2).Normal saline 5 μl was injected intrathecally instead of EphBI-Fc 1 h before operation and at 1 and 2 days after operation (groups S1 and C1 ) or on 5th day after operation (groups S2 and C2 ).Pain withdrawal latency to noxious thermal stimulation (PWL) and pain withdrawal threshold to noxious mechanical stimulation (PWT) were measured before operation and at 1,3 and 5 d after operation.The animals were sacrificed at 5 d after operation after measurement of pain threshold.The lumbar segment of spinal cord (L4-6) was removed for determination of c-Fos,PI3K and phosphorylated Akt(p-Akt) expression.Results CCI significantly reduced PWL and PWT and up-regulated spinal c-Fos,PI3K and p-Akt expression in groups C1 and C2 as compared with groups S1 and S2.EphB1-Fc significantly decreased hyperalgesia and the upregulated spinal Fos,PI3K and p-Akt protein expression induced by CCI in groups E1 and E2 as compared with groups C1 and C2.Conclusion Spinal EphB receptor is involved in the development and maintenance of neuropathic pain through PI3K/Akt signal transduction pathway.

OBJECTIVETo explore the feasibility of the treatment of upper eyelid sulcus using the expanded polytetrafluoroethylene implanted in orbit.

METHODSFrom July 2009 to April 2011, a total of 16 patients with upper eyelid sulcus were treated for recreating youthful periorbital appearance. To correct this kind of clinical characteristic, expanded polytetrafluoroethylene with different size were used as the orbital implant to restore the orbital contents and reinforce the bony support. upper eyelid sulcus was reversed effectively.

RESULTSWith average 2.5 year follow up, upper eyelid sulcus of 16 cases was reversed effectively. No postoperative complication related to globe or affected normal physical function was found.

CONCLUSIONSThe technique of orbital implantation with Expanded Polytetrafluoroethylene is beneficial for the treatment of the upper eyelid sulcus.
