Objective This study was to evaluate the relative applicability of serum cystatin C(Cys C)-based formulas and serum creatinine-based formulas for renal glomerular filtration rate(GFR) of Chinese children with chronic kidney disease(CKD).Methods Six hundred and nine Chinese CKD patients of less than 18 years old were enrolled from January 2011 to October 2016 in Shengjing Hospital of China Medical University.The value for estimated GFR (eGFR) was derived from using the 11 formulas,and 99mTc-DTPA renal dynamic imaging was the golden standard of standard GFR(sGFR).SPSS 22.0 statistical software was used to compare the accuracy of each assessment formula and the correlation between GFR markers(Cys C, β2-MG) and sGFR.Results A total of 609 children were enrolled,including 332 patients in CKD stage 1 (211 males and 121 females),165 patients in CKD stage 2(99 males and 66 females),70 patients in CKD stage 3(43 males and 27 females),22 patients in CKD stage 4(13 males and 9 females),and 20 patients in CKD stage 5(16 males and 4 females).All of the formulas either overestimate or underestimate GFR in chil-dren with CKD. In contrast with other formulas,CKD-EPI formula and Filler formula performed better regardless of gender and age difference.Serum β2-MG and serum Cys C all showed a negative relationship with sGFR(respectively r= -0.478 and r= -0.585,P<0.01).Conclusion CKD-EPI formula and Filler formula provide the better approximation to sGFR than other formulas in Chinese children with CKD.Howev-er,we need to try our best to enroll more patients to develop a more accurate GFR estimation formula in Chinese children.

OBJECTIVETo investigate the outcomes after combined organ radical resection for the recurrent gastric cancer.

METHODSComplete clinicopathological data of 48 recurrent gastric cancer patients who received radical resection before and underwent reoperation again in the Sun Yat-sen Memorial Hospital and The Second Affiliated Hospital of Xinjiang Medical University from January 2008 to December 2013 were analyzed retrospectively. Of 48 patients, 32 received combined organ radical resection(radical group) and 16 received combined organ palliative gastric stump resection (palliative group).

RESULTSIn the radical group, one case(3.1%,1/32) died 5 days after operation due to hepatorenal syndrome and 9 had postoperative complications (28.1%,9/32), including external intestinal fistula, pancreatic fistula, biliary fistula and anastomotic bleeding. In the palliative group, only one patient(6.2%, 1/16) had postoperative pneumonia and partial intestinal obstruction, with lower complication morbidity as compared to the radical group(P<0.05). The median survival time was significantly longer in the radical group(36.0 vs. 11.5 months, P<0.01). The 1- and 3-year survival rates were 93.1%, 72.4% in the radical group, and 31.3%, 18.8% in palliative group, whose differences were statistically significant. Multivariate Cox regression analysis showed that clinical stage (HR:3.106, 95% CI:1.357-6.321, P=0.008), peritoneal metastasis (HR:10.167, 95% CI:3.230-35.234, P=0.000) and radical cure situation(HR:3.256, 95% CI:1.267-9.389, P=0.009) were independent prognostic factors.

CONCLUSIONThe combined organ radical resection can provide better survival for recurrent gastric cancer patients, while the indications should be controlled strictly with preoperative multidisciplinary assessment and precise surgical judgment in order to decrease the complication.

OBJECTIVETo examine the association between 24 h urinary sodium to potassium ratio and metabolic syndrome (MS) in Chinese adults.

METHODSA population-based cross-sectional study was conducted among Chinese adults aged 18-69 years in Shandong province in 2011. Data on 24 h urinary excretion of sodium and potassium and components of MS were examined. Participants were divided into four groups according to the quartile of 24 h urinary sodium to potassium ratio.

RESULTSOf the 1 906 Chinese adults eligible for final data analysis, 471 (24.7%) were with MS. After completion of multivariate logistic regression analysis, when compared to the participants with 24 h urinary sodium to potassium ratio < 4.3, the OR (95% CI) of participants with 24 h urinary sodium to potassium ratio during 4.3-5.6, 5.7-8.1, and ≥ 8.1 were 1.27 (0.93-1.71), 1.06 (0.78-1.46), and 1.45 (1.06-1.97), respectively (P values for linear trend < 0.05). As for the components of MS, the odds of central obesity and elevated blood pressure but not the odds of elevated triglycerides, low high density lipoprotein cholesterol and elevated fasting glucose, had significantly increases with successive 24 h urinary sodium to potassium ratio quartiles (P values for linear trends < 0.05).

CONCLUSIONThe 24 h urinary sodium to potassium ratio appeared significantly associated with the odds of MS.
