Objective To evaluate the soothing effects of hemodiafiltration on patients with refractoriness nephrotic edema and its influence on prognosis of nephrotic syndrome.Methods All the 15 cases involved had undergone hemodiafiltration periodically during acme edema and administered with the same standard loading dose of prednisone for 8 weeks.Meanwhile,clinical and lab indexes (urine volume,Cr,Bun,urinary protein,albumin) were measured.Results All patients improved in urine volume and renal function gradually after the treatment of hemodiafiltration for 1 to 3 times.By the 8th week of post-hemodiafiltration,urinary protein 24 h declines obviously[(6.42?2.31)g/d to (0.87?1.24)g/d].Conclusion Hemodiafiltration is an effective treatment in relieving retention of water,increasing the remission rate of protein urine,recovering patients' renal function and improving their prognosis to nephritic syndrome patients with severe refractory edema.

purpose: to investigate the adhesive properties of renal tubular epithelial cells on matrigel and compared with the following three cases: ischemia、hypoxia and ischemia & hypoxia(I/H).materials and methods: A micropipette aspiration technique was adopted to determine the adhesive mechanics of renal tubular epithelial cells on matrige. results: it showed that the adhesion of renal tubular epithelial cells on matrigel was higher than that of those three model, further more, a different factor was followed by different adhesive mechanic. conclusion: the adhesion of I/H is lower, the ischemia is higher, but all were lower compared with control. It suggested that effect of hypoxia on adhesive properties of renal tubular epithelial cells on matrigel is bigger than that of ichemia.

Objective To investigate the therapeutic effect of endothelial progenitor cells(EPCs) in ameliorating rat progressive focal segmental glomerular sclerosis(FSGS) model induced by adriamycin.Methods Bone marrow mononuclear cells from male SD rats,after cultured by adherence method,were identified as EPCs.Female SD rats were divided into normal control group,adriamycin induced renal disease(ADR) group,EPCs transplantation group.ADR group and EPCs group underwent unilateral nephrectomy and received 5,3 mg/kg of adriamycin via tail vein 1 week and 2 weeks after operation,while the control group underwent sham operation and received 0.9% sodium chloride solution of equal volume.The whole body irradiation by 5 Gy X ray was done 1 week after the 2nd injection of adriamycin,then immediately 1?106 EPCs were transplanted via tail vein.The rats in control group and ADR group were only injected with 0.9% sodium chloride solution after whole body irradiation.The body weight and urine protein were measured before operation(0 week) and 4(1 week after EPCs transplantation),8,12 and 16 weeks after nephrectomy.Y chromatosome incorporation was detected with in situ hybridization at the 4th and 16th week.The histological and ultrastructural changes of kidney were evaluated at the 16th week.Results At the 4th and 16th weeks,Y chromatosome positive cells could be found incorporation in the area of glomerular and tubular epithelial cells.Since the 4th week,the weight of rats in both ADR group and EPC group became significantly less than that in control group and since the 8th week that in ADR group became less than that in EPC group(P

ObjectiveTo investigate the treatment and safety of interferon ? plus Ribovirin for chronic hepatitis C after kidney transplantation. MethodsFive patients with chronic hepatitis C after kidney transplantation were administered with interferon ? (50 ?g) subcutaneously once a week, plus Ribovirin (600 mg) orally once daily. The levels of HCV-RNA, ALT and serum creatinine in patients’ serum were monitored monthly. ResultsFour in 5 patients presented normal ALT and negative HCV-RNA in serum 12 weeks after treatment, and obtained sustained viral response 24 weeks after interferon ? plus Ribovirin therapy. During treatment, renal graft rejection did not occur. The most frequent side-effects were the decrease of leukocyte and hemoglobin, myalgia and fever, but did not influence the course of treatment. ConclusionCombination of interferon ? with Ribovirin can be a valid therapeutic option in renal transplant recipients with hepatitis C, and shows no influence on the renal function.

BACKGROUND: Advanced oxidation protein products (AOPPs) are a crucial pathogenic link to such long-term uremic complications in hemodialysis patients as immune system dysregulation, accelerated atherosclerosis, dialysis-related amyloldosis and so on. However, basic studies on AOPPs are relatively few, and one of the main reasons is the fact that it is difficult to obtain AOPPs with high pudty and biological activity.OBJECTIVE: To prepare, pudfy and indentify AOPPs, with the hope of searching for a method of preparing AOPPs with high purity and biological activity.DESIGN, TIME AND SETTING: A single sample observation was completed in the Clinical Biochemistry Section of Ecsomatics Department, Third Military Medical University of Chinese PLA from September to November in 2008. MATERIALS: Human serum albumin (HSA) was provided by Chengdu Rongsheng Company Ltd. Hitrap 26/60 sephacryl S-300 was purchased from GE Healthcare.METHODS: Hypochloric acid was used in the oxidation of purified HSA to prepare in vitro the AOPPs-modified HSA (AOPPs-HSA), which was then isolated by Hitrap 26/60 sephacryl S-300. Relative molecular mass was determined by sodium dodecyl sulfate polyacrylamide gel electropheresis (SDS-PAGE), native polyacrylamide gel electrophoresis (PAGE) and molecular weight standards. Structural features and biological activities were identified in the experiment of tumor necrosis factor α (TNF-α) release from monocytes.MAIN OUTCOME MEASURES: ①The purification and gel electrophoresis results of HSA. ②The purification and gel electrophoresis results of AOPPs. ③The dose-effect relationship between AOPPs-HSA and TNF-α release from monocytes. RESULTS: The relative molecular mass of AOPPs-HSA was 670 000 according to SDS-PAGE, native PAGE and molecular weight standards. Moreover, AOPPs-HSA could encourage the release of TNF-α from monocytes. The time effects showed that TNF-α release volume significantly increased after 6 hours of stimulation by AOPPs-HSA (1 g/L) and reached a peak at hour 12. CONCLUSION: Highly purified and bioactive AOPPs can be successfully prepared by the above-mentioned method, which builds a basis for further study on AOPPs.

Objective To investigate clinieopathologic characteristics and therapy of local advanced welldifferentiated thyroid carcinoma.Methods Data of 23 cases of advanced well-differentiated thyroid carcinoma treated from Jan.1996 to Dec.2005 were retrospectively reviewed.The data included age,pathologic type,local invasion,operative plan,postoperative complications and survival duration.Results Histology showed there were 15 cases of papillary carcinoma,6 ca8es of follicular carcinoma,and 2 cases of papiIlary follicular carcinoma.8 cases had local invasion into recurrent laryngeal nerve,12 cases had invasion into trachea,3 cases had trachea and esophagus invasion,and 8 cases had suprahyoid muscle invasion.All the 23 cases underwent resection procedure.According to surgical procedure,they were divided into radical resection group(n=6),tumor resection group(n=14)and tumor debulking group(n=3).2 cases received radiotherapy after thyroidectomy in tumor debulking group.All patients were followed up.Overall survival rate after 1 year,3 years and 5 years Was 91.3%(21/23),82.6%(19/23),and 60.8%(14/23)respectively.Prognosis of radical tumor removal group and tumor resection group was obviously better than that of tumor debulking group.Conclusions Prognosis is good for local advanced well-differentiated thyroid carcinoma patients receiving resection.Protection of local organ function Can enhance postoperative life quality.

Objective To analyze the cognitive changes and influencing factors in patients with lacunar cerebral infarction after carotid artery intervention therapy. Methods Sixty lacunar cerebral infarction combined with carotid stenosis patients treated with artery intervention therapy (intervention therapy group) and 68 lacunar cerebral infarction without carotid stenosis patients treated with drug therapy (drug therapy group) were selected. The neuropsychological test was completed at entry and 1, 6, 12 months after entry, and the results were compared with 60 healthy controls (control group). The cognitive changes were observed. The neuropsychological test included mini mental state examination (MMSE), Montreal cognitive assessment scale (MoCA) and cognitive field test. Results There were statistical differences in other scores except the Stroop test C section and Wechsler adult intelligence scale (WAIS-RC) picture arrangement subtest at entry in intervention therapy group and drug therapy group compared with control group (P<0.05). There were no statistical differences in the all scores at entry between drug therapy group and intervention therapy group (P>0.05). In intervention therapy group, the MMSE scores, MoCA total score, Rey-Osterrieth complex figure test (ROCFT), auditory verb learning test (AVLT), and the WAIS-RC picture arrangement subtest, verbal fluency test, WAIS-RC digit span backwards subtest of performing function 12 months after entry were significantly better than those at entry, and there were statistical differences (P<0.05). MMSE score, MoCA total score, long-time delayed recall of ROCFT, the immediate recall, long-time delayed recall and short delayed recall of AVLT, semantic category fluency test of performing function and digit span backwards subtest of WAIS-RC 6 months after entry were significantly better than those at entry:(27.8 ± 2.2) scores vs. (26.4 ± 1.9) scores, (20.7 ± 2.3) scores vs. (19.3 ± 2.0) scores, (12.4 ± 3.2) scores vs. (10.8 ± 2.6) scores, (54.3 ± 10.6) scores vs. (49.9 ± 10.9) scores, (12.4 ± 2.0) scores vs. (11.2 ± 2.8) scores, (12.9 ± 2.0) scores vs. (10.6 ± 2.6) scores, (17.5 ± 4.0) scores vs. (15.4 ± 3.4) scores and (4.0 ± 0.9) scores vs. (3.5 ± 0.9) scores, and there were statistical differences (P<0.05). In drug therapy group, there were no statistical differences in the all scores 1 and 6 months after entry, compared with that at entry (P>0.05);the MMSE score, MoCA total score, ROCFT, the immediate recall, long-time delayed recall and short delayed recall of AVLT, WAIS-RC picture arrangement subtest, verbal fluency test, WAIS-RC digit span backwards subtest of performing function and digit span backwards subtest of WAIS-RC 12 months after entry were significantly better than those at entry, and there were statistical differences (P<0.05). There were no statistical differences in all scores 12 months after entry between intervention therapy group and drug therapy group (P>0.05). In patients intervention therapy group, Logistic regression analysis showed that the MoCA score was related with age, hypertension and low education level (P<0.01 or<0.05), but was not related with smoking, diabetes and interventional treatment (P>0.05). Conclusions Cognitive impairment in patients with lacunar cerebral infarction and carotid stenosis is severe and extensive, but most cognition disorders can improve to normal level 12 months after artery intervention therapy.
