Objective:To investigate the effect of EPO on humoral and cellular immunity and the monocyte antigen presenting function in patients with chronic renal failure(CRF).Methods:60 patients with CRF were divided into three groups.Group A patients accepted hemodialysis and treated with EPO.Group B patients treated with EPO and didn't accept hemodialysis.Group C patients didn't accept EPO treatment and hemodialysis.After 8 weeks treatment,the subpopulations of T lymphocyte were analyzed with detected by flow cytometry analysis method;Immunoglobulins were measured with radioactive immuntzation method.In addition,the infection rate of patients with CRF in every group was compared.Results:The parameters of immune functions of patients with CRF were comparable between groups before treatment.After treated with EPO for 8 weeks,RBC numbers and Hb were significantly increased in patients of group A and group B,but not in patients of group C.IgG and IgA were increased in patients of groups A and groups B and have statistic differences as compared with that in patients of group C(P

Objective:To evaluate and compare the effciency and safety of Cyberwand dual probe lithotriptor and Swiss lithoclast master in percutaneous nephrolithotomy for renal staghorn calculi.
Methods:A total of 138 patients with renal staghorn calculi were divided randomly into a Cyberwand dual probe lithotripter group (Group A, n=71) and a Swiss lithoclast master group(Group B, n=67). hTe data for operative time, blood loss volume, one-stage calculus clearance rate, hospitalization time, cost of hospitalization and complication in the two groups were collected and compared.
Results: The renal access was established successfully and the one-stage percutaneous nephrolithotomy (PCNL) was performed in the 2 groups. There was no significant difference in the size of stones, the age of patients and the complications between the 2 groups before the operations. Intraoperative gravel time in the Group A was signiifcantly shorter than that in the Group B (77.14±21.39 vs 84.25±20.62, P=0.049). There was no significant difference in the one-staged stone clearance rate, blood loss volume in the operation between the 2 groups. hTe one-staged stone clearance rate in the 2 groups were 67.6%(48/71) and 70.1%(47/67) respectively, with no signiifcant difference (P=0.854).
Conclusion:Two lithotrities were safe and effcient for renal staghorn calculi. But comparing with Swiss lithoclast master, Cyberwand dual probe lithotriptor is more effcient and convenient.

Objective To study the influence of furosemide on the currents of the delayed rectification potassium channel and sodium channel of mice's spiral ganglion neurons.Methods Postnatal mice(P1～P6) spiral ganglion neurons were obtained by mechanical dissociation and enzymolysis.Delayed rectification potassium channels' currents and sodium channels' currents were recorded with whole-cell patch clamp techniques.Observed was the influence of furosemide on potassium channels and sodium channels.Results When furosemide was added around the spiral ganglion neurons,the delayed rectification potassium currents were inhibited to around +200～+300 pA,and sodium currents were inhibited to about 30% of peak current.Furosemide was washed away after working steadily for 1 minute,5 and 10 minutes.The delayed rectification potassium currents could recover to 98%,64%,and 25% of the peak currents before and sodium currents could recover to 96%,76% and 54% of the peak currents accordingly.Conclusion The currents of delayed rectification potassium channels and sodium channels could be inhibited by furosemide to different degrees.The longer furosemide was used,the greater damage could occur in the ion channels.

Objective To investigate and evaluate the feasibility and analgesic effect of ultrasound guided intercostobrachial nerve (ICBN) blockade in patients with persistent pain after radical mastectomy with ICBN preservation.Methods In a total of 53 following-up female cases,aged 18-55 years,ASA Ⅰ or Ⅱ,receiving radical mastectomy with ICBN preservation during January,2014 to February,2016,19 patients complained persistent pain in the lateral chest,axilla and/or upper arm more than 3 months after the surgery were enrolled.ICBN blockade was performed using 0.5% ropivacine 10 mL injected in the potential space between the superior of pectoralis minor muscle and the inferior of serratus anterior muscle in the second intercostal space guided by ultrasound.Visual analogue scale (VAS) was applied to assess the pain intensity at rest,on movement,and with 100 kPa pressure before blockage and 30 min thereafter,and then the pain intensity (SPI) was calculated.All nerve blockade-related adverse events including local anesthetic-related allergy,central nervous system and cardiovascular toxicity were recorded.Seven-day follow-ups were required in all patients to assess the pain intensity.Results All 19 cases completed ICBN blockade guided by ultrasound,of which 17 cases completed the seven-day follow-ups.The mean difference in SPI was-9.19 VAS points (95%CI-11.24--7.14,P<0.01).Compared with each mean VAS and SPI before block,all that after block at day 1-6 were significantly decreased (P<0.01 or P<0.05).There were 14(82.4%),13(76.5%),7(41.2%) and 3(17.6%)cases that SPI was decreased over 5 points after block at day 1-4.No nerve blockade-related adverse event was observed.Conclusion Ultrasound guided ICBN blockade can relieve persistent post-mastectomy pain safely and effectively.

Objective To discuss the diagnosis and treatment of carcinoma of renal pelvis ac-companied with kidney stones. Methods Twenty-one cases of carcinoma of renal pelvis with kidney stones were reviewed. The urinary stones history was from 10 d to 24 years with an average of 27 months. Four cases had recurrent fever, weight loss. Seventeen cases had gross hematuria. CT scan-ning was performed in 17 cases, which indicated 9 cases of carcinoma of renal pelvis, 4 cases of possi-ble renal mass and enlarged renal hilum lymph nodes. MRU was performed in 10 cases, which showed 9 cases of stones concomitant with carcinoma of renal pelvis. IVU indicated 13 cases of light filling of contrast and 8 cases of complete negative filling. Nine cases who had been diagnosed before surgery were performed radical nephrectomy and local lymph nodes dissection. Five cases were carried out ne-phrostomy first because of pyonephrosis, then secondary subcapsule nephrectomy was performed, 2 of them who were diagnosed with carcinoma of renal pelvis after surgery were performed with ureterecto-my and excision of bladder cuff. Three cases were performed with subcapsule nephrectomy because of dense perinephric adhesion. Three cases with complicated calculi and nonfunctional kidney were per-formed with nephroureterectomy, 2 of them who were diagnosed with carcinoma of renal pelvis were carried out with ureterectomy and excision of bladder cuff. One case who was performed PCNL under ultrasound guidance was found a mass in the renal pelvis. The pathological examination indicated ade-nocarcinoma. Radical nephrectomy and lymphadenectomy of renal hilum were performed afterwards. Resnlts Twenty-one cases were performed with pathological examination, in which there were 4 ca-ses of transitional cell carcinoma, 16 cases of squamous cell carcinoma and 1 case of adenocarcinoma. All the 21 cases were discharged after surgery. Nine of them were followed up with 4 to 28 months. Six cases were dead. The post-surgery survival time was 3 to 21 months. Two of them died of heart infarction, 4 died of metastasis. Conclusions The carcinoma of renal pelvis should be considered be-fore surgery in the patients with long history of renal calculi, hydronephrosis and infection. CT scan-ning and MRU are helpful for the diagnoses of renal calculi concomitant with carcinoma of renal pel-vis. Earlier diagnosis, earlier management of renal calculi can extend survival time of the patients with renal calculi concomitant with carcinoma of renal pelvis.

Objective To explore whether LDL and oxLDL may induce kidney tubular epithelial-mesenchymal transition (EMT) and its mechanism. Methods The second generation human kidney tubular epithelial cells (TECs) were cultured for 24 hours in different conditions as (1) serum free as control, (2) treated with LDL (50 ?g/ml) , (3) treated with oxLDL(50 ?g/ml), (4) treated with LDL(50 ?g/ml) plus PD98059(5 ?mlo/L) , (5) treated with oxLDL(50 ?g/ml) plus PD98059 (5 ?mol/L). The expression of cytokeratin, E-cadherin, ?-SMA and vimentin was assessed by immunofluorescence and Western-blot. Western-blot was also performed to test the expression of collagen I and phospho-ERKl/2MAPK and phospho-GSK-3?. Results oxLDL was more potently in inducing tubular EMT than LDL at 24 hours as demonstrated by de novo a-SMA expression, increased expression of vimentin, partial loss of cytokeratin and reduction of E-cadherin expression by TECs. The expression of collagen I and phospho-ERKl/2MAPK and phospho-GSK-3? was increased in TECs stimulated by LDL or oxLDL. MAPK inhibitor (PD98059) inhibited the phosphorylation of GSK-3P and almost completely blocked oxLDL-induced tubular EMT. However, PD98059 alone was able to inhibit LDL-induced tubular EMT partially. Conclusions oxLDL is more potently in inducing tubular EMT than LDL. The ERKl/2MAPK-GSK-3? signaling pathway mediates the LDL or oxLDL-induced tubular EMT.

Objective To investigate the relationship among urinary protein molecular weight of IgA nephropathy ,renal tubu‐lointerstitium damage and clinical index ,and discuss the role of low molecular weight urinary protein in the mechanism of IgA pro‐gression .Methods A total of 34 patients with biopsy proven IgAN were studied .We detect the molecular weight of urinary protein by SDS‐PAGE .Data were processed with the classes of tubulointerstitial lesions and laboratory tests such as 24h urinary protein quantitation and serum creatinine(Scr) .Results The urinary protein were divided into four types according the SDS‐PAGE:the ball urinary protein group ,physiologic urinary protein group ,23 × 103 proteinuria group and 10 × 103 proteinuria group .Scores of tubu‐lointerstitial lesions ,twenty four hour urine protein quantitation and Scr level were all significantly higher in 10 × 103 proteinuria group than 23 × 103 proteinuria group (P<0 .05) .Conclusion 10 × 103 proteinuria may have close relationship with the progression of IgAN ,and it may be a useful index for the degree of tubulointerstitial lesions of IgAN .

Objective To investigate the expression and significance of glucogen synthase kinase-3β (GSK-3β) in the pathogenesis of chronic allograft nephropathy (CAN) in rats.Methods Kidneys of Fisher (F344) rats as donors were orthotopically transplanted into Lewis (LEW) rats as recipients.The renal function and histopathological changes were observed at 4,8,12,16,and 24week post-transplantation.Phosphorylated GSK-3β (p-GSK-3β) protein and mRNA expression was determined by using immunohistological assays and RT-PCR respectively.Results Our data showed that 24-h urinary protein excretion in CAN rats was increased significantly at week 16 as compared with F344/LEW controls.Allografts showed markedly increased mononuclear cells infiltration and presented with severe interstitial fibrosis and tubular atrophy at 16 and 24 week post-transplantation.p-GSK-3β expression (protein/mRNA) was down-regulated in rat kidneys with CAN,and the decrease became more significant over time after transplantation.p-GSK-3β expression was correlated significantly with 24-h urinary protein excretion,serum creatinine levels,tubulointerstitial mononuclear cells infiltration,smooth muscle cells migration in vascular wall,and interstitial fibrosis.Conclusion It was concluded that GSK-3β down-regulation was the key event that may be involved in mononuclear cells infiltration and vascular SMCs migration at early stage,and interstitial fibrosis and allograft nephroangiosclerosis at later stage of CAN pathogenesis in rats.

Objective To investigate the role and mechanism of phosphate myosin light chain (pMLC) in the rat kidney of chronic allograft nephropathy (CAN) model. Methods The left donor kidneys from Fisher (F344) rats were orthotopically transplanted into Lewis recipients. Meanwhile, the F344 rats and LEW rats with resection of the right kidney served as control groups. Animals were harvested respectively at the 4th, 8th and 12th week after transplantation. The creatinine clearance rate (CCr) was calculated by urine creatinine of 24-h urine. Blood samples were collected from rats for determination of serum creatinine. The expression of pMLC was detected by using Western blotting and immunohistochernistry, and that of integrin-linked kinase (ILK) by using immunohistochemistry. Results Mononuclear cells infiltration of allografts was markedly aggravated as compared to the controls. Allografts got severe interstitial fibrosis and tubular atrophy at 12th week after transplantation. The expression of pMILC and ILK was up-regulated in the kidney of CAN rats after transplantation, and increased more significantly as the time went on. The expression of pMILC was significantly correlated with 24-h urine protein excretion (r= 0. 273, P＜0. 05), serum creatinine levels (r = 0. 434, P＜0. 01 ), the number of tubulointerstitial infiltrated mononuclear cells (r = 0. 525, P＜0. 01 ), the number of smooth muscle cells (SMC) in vascular wall (r= 0. 676, P＜0. 01 ) and the extent of interstitial fibrosis (r= 0. 570, P＜0. 01 ).There was a significantly positive correlation between ILK and pMLC in CAN rats at the 4th week after transplantation (r= 0. 778, P＜0. 01 ). Conclusion pMLC might play an key role in CAN, and the over-expression of ILK might be involve in the pathogenesis of CAN.
