Objective To compare the influence of hemodialysis (HD) and peritoneal dialysis (PD) on early outcome of patients underwent kidney transplantation from donation after cardiac death (DCD).Methods Patients admitted in the First People's Hospital of Foshan with DCD kidney transplant from January 1st,2011 to June 30th,2016 were analyzed retrospectively.Recipients were grouped into HD group (n=61) and PD group (n=28) according to their pre-transplant dialysis modality.Their short-term outcomes after DCD kidney transplant were compared,including recovery of renal function,short-term complications and laboratory data.Results Patients had longer dialysis duration and lower hemoglobin,serum albumin and phosphorus in PD group than those in HD group (all P ＜ 0.05),but no significant difference shown in age,gender,body mass index,primary disease,blood pressure,and hepatitis B infection (all P ＞ 0.05).HD patients with 6.00(4.00,11.00) d recovery time of renal function,18.00(17.00,21.50) d hospital time,had 24.59％ the delayed graft function (DGF),3.28％ acute rejection and 16.39％ infection during hospitalization.While for PD patients the recovery time of renal function was 4.00(3.75,7.00) d;hospital time was 19.00(15.00,21.75) d;the incidence rate of DGF was 14.29％;acute rejection was 3.57％;and infection during hospitalization reached 17.86％.Above indexes were not significantly different between HD and PD groups (all P ＞0.05).Repeated measure ments showed that,compared with those before transplant surgery,after 1 month,3 months and 6 months HD and PD groups had decreased creatinine and phosphorus,and increased hemoglobinserum albumin and calcium;Serum albumin and calcium were different between the two groups (P ＜ 0.001,P=0.040),whereas creatinine,hemoglobin and phosphorus did not show difference (all P ＜ 0.05).After transplantation the trends of creatinine,hemoglobin,calcium and phosphorus were not different between the two groups (P values were 0.295,0.310,0.501 and 0.063,respectively).Conclusions No significant difference of the recovery regarding renal function,anemia,nutrition status and mineral metabolites was found between pre-transplant HD and PD modality in patients who underwent DCD kidney transplantations.

This paper reports a case of peritonitis caused by Campylobacter fetus in a continuous ambulatory peritoneal dialysis (CAPD) patient. The patient was a middle-aged man, with chronic kidney disease stage 5 secondary to chronic glomerulonephritis, and had been on CAPD for 6 years. He was admitted to our department with a 7 day history of abdominal pain and cloudy effluent. Peritoneal effluent culture was negative and metagenomic next-generation sequencing suggested Campylobacter fetus. Intraperitoneal treatment with amikacin was failed. Peritoneal dialysis catheter was removed and hemodialysis treatment was performed. After treatment of erythromycin oral for 4 weeks, the patient's symptoms was improved and discharged.

OBJECTIVETo investigate the impact of androgen receptor splice variant 7 (AR-V7) expression on overall survival for patients with metastatic prostate cancer.

METHODSThe data of 113 diagnosed metastatic prostate cancer patients from January 2002 to June 2010 were collected retrospectively, including patient's age at diagnosis, prostate-specific antigen (PSA) level at diagnosis,Gleason score, clinical stage, PSA nadir during hormonal therapy, the time to PSA nadir, vital status, survival time and cause of death. The expression of AR-V7 in prostate cancer tissue was detected by using immunohistochemical staining. The correlation of AR-V7 expression and patient clinicopathological characteristics in all patients were analysed using Student t-test or Chi-square test. Cox proportional hazards regression models were used to evaluate the predictive role of AR-V7 expression and patient characteristics for overall survival.

RESULTSThe median PSA nadir was 0.7 µg/L (ranged from 0.0 to 143.0 µg/L). The median time to PSA nadir was 8.1 months (ranged from 0.9 to 71.0 months). The follow-up was performed until March 12, 2014. During the follow-up period, 67 of 113 metastatic prostate cancer patients (59.3%) died and the median overall survival was 96 months (ranged from 5 to 135 months). The AR-V7 detection rate was 20.4% (23/113). The serum PSA level in patients with positively expression of AR-V7 was significantly higher than that without AR-V7 expression (t = 2.521, P = 0.013). Multivariate Cox regression analysis indicated that the expression of AR-V7 (HR = 2.421, P = 0.002) and time to PSA nadir (HR = 1.019, P = 0.022) were independent prognostic factors of overall survival for metastatic prostate cancer patients.

CONCLUSIONSThe expression of AR-V7 in prostate cancer tissues and time to PSA nadir during hormonal therapy are independent prognostic factors of overall survival for metastatic prostate cancer patients. Therapy targeting AR-V7 may improve prognosis of metastatic prostate cancer patients.

Objective:To determine whether the early stage platelet count can predict the outcome of peritoneal dialysis-associated peritonitis (PDAP).Methods:A retrospective cohort study was conducted by selecting PDAP patients who were hospitalized in the First People's Hospital of Foshan from January 2012 to January 2019. According to the final treatment outcome, the patients were divided into cured group and withdrawn group. The withdrawn group included patients who transferred to hemodialysis or died. Basic data on demography, blood routine examination, peritoneal fluid, biochemical indicators were compared between the two groups. Logistic regression analysis was used to analyze the withdrawn risk factors of PDAP.Results:There were 180 patients included in the study, including 112 cases in the cured group and 68 cases in the withdrawn group. Compared with the cured group, there were older age [(53.38±14.17) years old vs (48.41±13.04) years old, t=2.407, P=0.017], longer age of dialysis [(49.20±26.05) months vs (30.36±32.97) months, t=4.034, P<0.001], longer hospital stay [(23.88±11.50) d vs (17.80±3.95) d, t=5.133, P<0.001] and higher platelet count [(285.55±107.23)×10 9/L vs (234.90±74.03)×10 9/L, t=3.450, P=0.001], lower serum albumin [(31.72±7.47) g/L vs (35.40±4.93) g/L, t=-3.972, P<0.001] in the withdrawn group. Multivariate logistic regression analysis showed that longer dialysis age ( OR=1.012, 95% CI 1.007-1.024, P=0.015) and higher platelet count ( OR=1.013, 95% CI 1.004-1.026, P=0.008) were independent risk factors, and higher serum albumin ( OR=0.941, 95% CI 0.896-0.988, P=0.005) was an independent protective factor of withdrawal from peritoneal dialysis in PDAP patients. Conclusions:The long dialysis age, early high platelet count are independent risk factors and high serum albumin level is an independent protective factor for withdrawal from peritoneal dialysis in PDAP patients.

Objective:To analyze the clinical efficacy of two-stage total hip arthroplasty in the treatment of chronic septic hip arthritis.Methods:From January 2008 to March 2020, 17 patients with chronic septic hip arthritis (17 hips) received two-stage total hip arthroplasty at Department of Orthopaedic Surgery, The First Affiliated Hospital to of Fujian Medical University. They were 11 males and 6 females, with an average age of 54.5 years (from 19 to 77 years) and 9 left and 8 right hips affected. There were 10 cases of primary septic hip and 7 cases of secondary infection after hip surgery. Three patients had undergone debridement in other hospitals and one patient had developed a sinus tract. In the first stage operation, the diseased femoral head and neck were resected to implant an articulating spacer after thorough debridement; in the second stage operation, the spacer was removed to implant a uncemented artificial hip prosthesis in 16 cases or a cemented artificial hip prosthesis in one case. Recorded were the results of microbial culture, operation time, intraoperative blood loss, and therapeutic outcomes of the patients.Results:Pathogenic data were available in 13 patients and the culture was negative in 4. The pathogens were detected by metagenomic next-generation sequencing in 2 patients with culture negative. In the first stage operation, operation time averaged 140.6 min (from 90 to 176 min) and intraoperative blood loss 361.8 mL(from 100 to 1 000 mL); in the second stage operation, operation time averaged 130.3 min (from 91 to 166 min)and blood loss 291.2 mL(from 50 to 700 mL). The average interval between the first and the second stage operations was 115.0 days(from 66 to 227 d). During the interval, spacer fracture occurred in one case, spacer dislocation in one case and lower extremity deep venous thrombosis in one case. All the patients were followed up for 12 to 82 months (average, 36.7 months) after second stage operation. The inflammatory indexes decreased to normal in all the 17 patients and infection recurrence was observed in none of them.Conclusions:Two-stage total hip arthroplasty may result in a high rate of successful treatment of chronic septic hip arthritis. Specific use of sensitive antibiotics after identification of specific pathogenic microorganisms by multiple methods is the key to a successful treatment.

Objective:Objectives To investigate the predictive value of color Doppler flow imaging (CDFI) for the proteinuria following pyeloplasty for congenital ureteropelvic junction obstruction (UPJO) in children.Methods:We identified a series of 206 children with a mean age of (20.0±28.8) months (1-132 months), consisted of 171 males and 35 females, diagnosed with congenital UPJO accepted pyeloplasty from January 2014 to September 2018, the preoperative mean urinary Albumin/Creatinine Ratio (ACR) was (17.3±160.1) mg/mmol and the mean β2-microglobulin/Creatinine Ratio (β2-MG/Cr) was (135.6±383.8) μg/mmol, ultrasound showed a mean renal pelvis dilatation of (3.1±1.5) cm and a mean cortical thickness of (0.3±0.1) cm, and classified as grade Ⅰ-Ⅴ according to the blood flow distribution in renal by CDFI, these children were divided into three groups of increased, decreased and unchanged blood flow according to the postoperative CDFI within 1 week, the postoperative urinary protein and renal function indexes within 1 week and 2 years were retrospectively analysed among groups.Results:Within 1 week postoperatively, an increased, decreased and unchanged blood flow occurred in 113 (54.9%), 31(15.0%), 62(30.1%) children, respectively. Urinary ACR in above mentioned groups was (112.3±400.7), (16.1±29.3), (32.7±48.4) mg/mmol, β2-MG/Cr was (887.4±6061.0), (50.2±62.7), (51.9±57.8)μg/mmol, there were significant differences among groups ( P<0.01). Contralateral hydronephrosis occurred in 21(18.6%), 4(12.9%), 8(12.9%) children, urinary N-Acetyl-β-D-glucosaminidase (NAG) was (7.5±5.2), (7.0±5.4)、(5.7±4.5) U/L, these indexes showed no significant differences among groups. There was a positive correlation between the increased blood flow level and the decreased renal pelvis dilatation (Spearman’s correlation coefficient 0.2, P<0.01), ACR (Spearman’s correlation coefficient 0.4, P<0.01) and β2-MG/Cr (Spearman’s correlation coefficient 0.3, P<0.01). After a follow up of 2 years, 67 children were diagnosed with proteinuria in this series, 51 cases of them with an increased blood flow, which had significantly higher percentage than children with a decreased (4 cases, 12.9%) or unchanged blood flow (12 cases, 19.3%). Logistic multivariate analysis indicated that early postoperative (within 1 week) increased blood flow ( OR=1.9, 95% CI 1.5-2.6), contralateral hydronephrosis ( OR=2.2, 95% CI 1.1-4.8) and urinary NAG ( OR=1.1, 95% CI 1.0-1.1) were predictive of proteinuria, the increased blood flow was independent predictor of proteinuria (Ⅰ level increased: OR=1.9, 95% CI 1.5-2.6). Conclusions:The CDFI reveals good predictive value for the postoperative proteinuria, an early marked increased blood flow postoperatively indicated risk of proteinuria in the long term.
