OBJECTIVE: To investigate the effect of parathyroidectomy(PTX)on the progression of renal anemia and erythropoietin dose in maintenance hemodialysis(MHD)patients with secondary hyperparathyroidism(SHPT)of uremia. METHODS: A total of 58 MHD patients with SHPT treated with PTX were retrospectively analyzed. The changes of serum intact parathyroid hormone(iPTH), calcium(Ca), phosphorus(P), alkaline phosphatsae(AKP), hemoglobulin(Hb), hematocrit(Hct), serum ferritin(SF), transferrin saturation(TS), c-reactive protein(CRP), albumin(Alb)and Kt/V at 3 months and6 months after PTX treatment were evaluated. The Hb level at 3 and 6 months after surgery and the doses of recombinant human erythropoietin(EPO)were recorded. RESULTS: Serum iPTH decreased dramatically(before PTX 1828.88±811.2 ng/L,three months after PTX 56.75±158.4 ng/L,six months after PTX 64.52±178.5 ng/L, P<0.05); Ca, P and AKP levels also decreased significantly after PTX(P<0.05). Hb increased after PTX(before PTX 99.92±14.26 g/L, six months after PTX123.2±13.65 g/L, P<0.05); meanwhile, the dose of EPO decreased after the operation[before PTX 235.18±62.65 U/(kg·W), three months after PTX 158.78±34.24 U/(kg·W),six months after PTX 112.53±25.37 U/(kg·W), P<0.05]. CONCLUSION: PTX can effectively control secondary hyperparathyroidism, significantly improve the renal anemia, and decrease dose of erythropoietin in MHD patients with SHPT.

OBJECTIVE: To investigate the clinical and pathological features in hyperuricemic IgA nephropathy,and the effect of hyperuricemia on progression of IgAN.METHODS: Patients with IgAN confirmed by renal biopsy were enrolled.Those patients were admitted to the First Affiliated Hospital of Fujian Medical University from January 2006 to December 2016.The relationship between uric acid and clinical and pathological changes was analyzed.Patients were followed up and the level of serum creatinine was measured.Primary endpoint was double of creatinine or end-stage renal disease(ESRD)or renal replacement therapy.Risk factors of progression in IgAN were assessed using Kaplan-Meier and Cox proportional hazards analyses.RESULTS: A total of 231 patients with IgAN either reached the endpoint or followed up for more than 2 years were enrolled.Among these patients,the prevalence of hyperuricaemia was 39.8%.There were significant differences in gender,systolic blood pressure,diastolic blood pressure,serum creatinine,blood urea nitrogen,24-hour urine protein,eGFR,degree of tubule atrophy/interstitial fibrosis between high(H-UA)group and normal(N-UA)uric acid group(P<0.05).A total of29 patients reached the endpoint.Univariate COX regression analysis showed that there were significant differences between the progressive group and the non-progressive group in glomerulosclerosis,renal tubular atrophy/interstitial fibrosis,24-hour urine protein quantification,hyperuricemia,anemia,hypertension,blood creatinine,and blood urea nitrogen(P<0.05).Kaplan-Meier survival curve suggested that renal survival was lower in H-UA IgAN group.Anemia,24-hour urine protein,glomerulosclerosis,and serum creatinine are independent risk factors for progression of Ig AN assessed by multivariate analysis.CONCLUSION: Hyperuricemia may be positively associated with severe clinical and pathological damage,more renal tubular atrophy/interstitial fibrosis lesions,and lower renal survival.

<p><b>Objective</b>To compare the level of testosterone between type-2 diabetes mellitus (T2DM) patients and healthy controls and to investigate the status of hypogonadism and the influence of hypopgonadism on the quality of life.</p><p><b>METHODS</b>We collected serum total testosterone (TT), free testosterone (FT), sex hormone-binding globulin (SHBG), and other clinical data from 166 T2DM patients aged over 30 years and 186 age-matched healthy controls. We investigated the quality of life (QoL) of the two groups of subjects using the questionnaires of Androgen Deficiency in Aging Males (ADAM), Aging Male Symptoms (AMS), 36-Item Short-Form Health Survey (SF-36), and Special Quality of Life for Diabetes Mellitus (DSQL).</p><p><b>RESULTS</b>The level of calculated FT (cFT) was remarkably lower in the T2DM patients than in the healthy controls (P<0.05), but no statistically significant differences were observed between the two groups in the levels of TT, bio-available testosterone (Bio-T), and SHBG. The T2DM males with hypogonadism showed significant differences from those without in age, height, systolic blood pressure, and creatinine (P<0.05). Based on the criteria of cFT <0.3 nmol/L and AMS score ≥27, the incidence rate of hypogonadism was 51.81% in the T2DM patients, 31.58% in the 30-39 yr group, 32.50% in the 40-49 yr group, 50% in the 50-59 yr group, 69.23% in the 60-69 yr group, and 77.27% in the ≥70 yr group, elevated by 77.4% with the increase of 10 years of age (OR = 1.774, P<0.001). The AMS score was significantly correlated with the scores of DSQL (r = 0.557, P<0.001) and SF-36 (r = -0.739, P<0.001) in the T2DM patients.</p><p><b>CONCLUSIONS</b>T2DM patients have lower levels of cFT than healthy men, accompanied with a higher incidence of hypogonadism. Age is a main risk factor of hypogonadism. Severer testosterone deficiency symptoms are associated with lower scores of QoL in T2DM males.</p>

<p><b>BACKGROUND</b>Data on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.</p><p><b>METHODS</b>The survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.</p><p><b>RESULTS</b>The analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).</p><p><b>CONCLUSIONS</b>The prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.</p>

<p><b>OBJECTIVE</b>To evaluate the clinical efficacy and safety of sequential treatment with alprostadil and beraprost sodium for chronic renal failure caused by chronic glomerulonephritis.</p><p><b>METHODS</b>Sixty-three patients with chronic renal failure due to chronic glomerulonephritis, after receiving a 2-week-long conventional treatment, were randomly divided into alprostadil group (n=20, with alprostadil injection at 10 µg/d for 2 weeks), sequential treatment group (n=21, with alprostadil injection at 10 µg/d for 2 weeks and oral beraprost sodium at 20 µg three times a day for 12 weeks), and strengthened sequential treatment group (n=22, with alprostadil injection at 20 µg/d for 2 weeks and a double dose of oral beraprost sodium for 12 weeks). Urinary albumin excretion rate (UAER), cystatin C (Cys C), blood urea nitrogen, creatinine, fibrinogen, D-dimer, prothrombin time (PT), and platelets were tested before and after the treatment, and the changes in urinary albumin discharge rate, serum creatinine, and glomerular filtration rate were determined.</p><p><b>RESULTS</b>The patients in strengthened sequential treatment group showed a significantly decreased change rate of urinary albumin discharge rate (P<0.01) than those in the other two groups. In the two sequential treatment groups, especially the strengthened treatment group, the change rate of glomerular filtration rate increased significantly compared with that in alprostadil group (P<0.01). Strengthened sequential treatment resulted also in significantly decreased increment of serum creatinine compared that in the other 2 groups (P<0.01). After 14 weeks of treatment, fibrinogen and D-dimer were decreased in all the 3 groups (P<0.05) to a comparable level between the 3 groups (P>0.05), and prothrombin time (PT) or platelet showed no significant changes (P>0.05).</p><p><b>CONCLUSION</b>Sequential treatment with alprostadil and beraprost sodium can improve the glomerular filtration rate and decrease urine albumin excretion rate, serum creatinine increase rate, and lower blood fibrinogen and D-dimer levels, thus delaying the progression of chronic renal failure caused by chronic glomerulonephritis. This therapy shows a dose-related effect with good clinical safety.</p>

<p><b>OBJECTIVE</b>To study whether alisol B could inhibit complement 3a (C3a) induced renal tubular epithelial-mesenchymal transition (EMT).</p><p><b>METHODS</b>The in vitro cultured human renal tubular epithelial HK-2 cells were intervened with 5 ng/mL transforming growth factor-beta (TGF-beta), 0.1 micromol C3a, and 0.1 micromol C3a + 10 micromol alisol B, respectively. The mRNA and protein expressions of alpha-SMA, E-cadherin, and C3 were detected using RT-PCR, Western blot, and immunofluorescence, respectively.</p><p><b>RESULTS</b>The mRNA and protein expressions of C3 in HK-2 cells were up-regulated after intervention of C3a (P < 0.01), the mRNA and protein expressions of alpha-SMA in HK-2 cells were obviously enhanced (P < 0.01), the mRNA and protein expressions of E-cadherin obviously decreased (P < 0.01). When compared with the group intervened by exogenous C3a, after intervention of alisol B, the mRNA and protein expressions of alpha-SMA in HK-2 cells were obviously reduced (P < 0.01), the mRNA and protein expressions of E-cadherin obviously increased (P < 0.05).</p><p><b>CONCLUSIONS</b>Exogenous C3a could induce renal tubular EMT. Alisol B was capable of suppressing C3a induced EMT.</p>
