Effects of Niaoduqing Particles () on Delaying Progression of Renal Dysfunction: A Post-trial, Open-Label, Follow-up Study / 中国结合医学杂志

OBJECTIVE@#To follow up the participants of the randomized clinical trial "Efficacy and Safety of Niaoduqing Particles () for Delaying Moderate-to-Severe Renal Dysfunction", and assess the long-term effects of Niaoduqing Particles on delaying the progression of renal dysfunction.@*METHODS@#Participants, who had previously been randomly assigned to receive Niaoduqing Particles or placebo for 24 weeks (146 cases in each group), were invited to follow-up and all were administered Niaoduqing Particles 5 g thrice daily and 10 g before bedtime for 24 weeks. The primary endpoints were changes in baseline serum creatinine (Scr) and estimated glomerular filtration rate (eGFR) after completion of the open-label treatment period.@*RESULTS@#After the double-blind period, the median (interquartile range) changes in Scr were 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) μmol/L for the Niaoduqing Particle and placebo groups, respectively (P=0.008), and the median changes in eGFRs were-0.2 (-4.3-2.7) and-2.21 (-5.7-0.8) mL•min•1.73 m, respectively (P=0.016). There were significant differences in the double-blind period changes in renal function between groups. After the open-label period, the median changes in Scr were 9.0 (-10.0-41.9) and 17.5 (-6.0-50.0) μmol/L for the Niaoduqing Particle and placebo groups according to baseline grouping, respectively (P=0.214), and the median changes in eGFRs were-2.3 (-6.4-1.9) and-3.7 (-7.5-1.1) mL•min•1.73 m, respectively (P=0.134). There were no statistical differences in the open-label period changes in renal function between groups. The eGFR reduction of participants who accepted Niaoduqing Particle treatment for 48 weeks was projected to 2.5 mL•min•1.73 m per year.@*CONCLUSION@#Niaoduqing Particles appear to have long-term efficacy for patients with moderate-to-severe renal dysfunction. Although there was no statistical difference, the early use of Niaoduqing Paticles seems to ameliorate the worsening of renal function. (Trial registration No. ChiCTR-TRC-12002448).

Use of arterial conduit for arterial revascularization during liver and multivisceral transplantation / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>At present, revascularization is still one of the most critical technologies in orthotopic liver transplantation (OLT). Hepatic artery (HA) variations occur frequently in both donors and recipients. Moreover, there are always some pathological changes in the recipient hepatic artery. If handled improperly, it may cause complications after anastomosis. Therefore, arterial conduit could be used in primary OLT, re-OLT and multiple-OLT. This study aimed to investigate the indications, methods and techniques with usage of arterial conduit for HA revascularization during adult OLT.</p><p><b>METHODS</b>We reviewed 1200 patients of consecutive OLTs performed during 2000 - 2009 in the First Affiliated Hospital of Sun Yat-sen University. Of these patients, 48 recipients with artery variations received HA revascularization with usage of arterial conduit and special postoperative managements. The indications, methods, techniques, and the managements of postoperative complications in adult OLT with usage of arterial conduit for HA revascularization were analyzed.</p><p><b>RESULTS</b>In 48 cases with artery bypass, the arterial conduit were anastomosed between donor hepatic artery and recipient infrarenal aorta (n = 32), between donor hepatic artery and recipient suprarenal aorta (n = 10), and between donor upper abdominal organ cluster artery and recipient suprarenal aorta (n = 6). The technique was applied in 4% (48/1200 cases) of the whole OLTs performed in the same period, and the patency rate of the conduits was 100%. Forty patients (83.3%) survived, and the average survival time was 3.9 years. Eight patients (16.7%) died (all due to tumor recurrence), while the average survival time was 1.2 years. All these patients have not experienced artery-related complications in their survival time.</p><p><b>CONCLUSIONS</b>When recipient HA has variations or pathological changes in OLT, the donor artery should be anastomosed to recipient abdominal aorta with an arterial conduit to achieve satisfactory outcomes. For arterial anastomosis can not be routinely performed, donor iliac artery as a conduit to be anastomosed with the recipient abdominal aorta is safe and effective.</p>

Cardiovascular risk profile in systemic lupus erythematosus: a cross-sectional study of 879 patients / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the prevalence of cardiovascular diseases (CVD) in patients with systemic lupus erythematosus (SLE) and estimate the associated risk factors for CVD.</p><p><b>METHODS</b>This cross-sectional study was conducted in 879 SLE patients treated in our hospital between March, 2006 and March, 2011. The demographic data and the clinical data including SLE duration, therapeutic regimen, renal pathological data, estimated glomerular filtration rate (eGFR), SLE Disease Activity Index (SLEDAI), and associated biochemical parameters were analyzed. Cardiovascular ultrasound was used for detecting and analyzing the cardiovascular structural and functional abnormalities.</p><p><b>RESULTS</b>Eighty-five cases of CVD were found in the 879 SLE cases (9.7%). After age stratification, CVD was identified in 5.8%, 9.0%, 14.0% and 20.0% in SLE patients aged ≤19, 20-39, 40-59 and ≥60 years, respectively, showing a tendency to increase with age (P=0.002). The prevalence of CVD differed significantly between patients with and those without lupus nephritis (P=0.001). Among the 85 patients with CVD, 23.5% (20/85) had left ventricular hypertrophy, 49.5% (42/85) had congestive heart failure, 20.0% (17/85) had stroke, 3.5% (3/85) had angina pectoris, and 3.5% (3/85) had peripheral CVD. Compared to those without CVD, patients with CVD had a longer SLE duration (P=0.002), a longer time of steroids treatment (P=0.026), a higher blood pressure (P=0.0006), a lower eGFR (P=0.001), and a lower concentration of HDL (P=0.007). Logistic regression analysis showed that SBP, eGFR, HDL, SLE duration, SLEDAI index, serum C3 and hs-CRP were the risk factors for CVD in SLE patients (P=0.033).</p><p><b>CONCLUSION</b>SLE is associated with a high risk of CVD which increases with age, and SLE patients with lupus nephritis have an even higher risk for CVD. SBP, eGFR, HDL, SLE duration, SLEDAI index, serum C3 and hs-CRP are the risk factors for CVD in SLE patients.</p>
