Journal of International Oncology 2016;43(1):8-11
Objective To evaluate the efficacy and safety of sunitinib versus sorafenib in the first-line treatment of advanced renal cell carcinoma.Methods Forty-two patients with advanced renal cell carcinoma were divided into two groups according to the therapeutic method.Twenty patients were treated with sunitinib (50 mg, oral administration, once a day, for 4 weeks, drug withdrawal of 2 weeks, 6 weeks was a cycle) and 22 patients were treated with sorafenib (400 mg, oral administration, twice a day, until the disease progression, 6 weeks was a cycle).The efficacy and toxicity were evaluated every 2-cycle treatment.Results All 42 patients could be evaluated.The disease remission rate (RR), disease control rate (DCR) of sunitinib group and sorafenib group were 30.0% (6/20), 22.7% (5/22), 90.0% (18/20), 77.3% (17/22) respectively,the median progression free survival (PFS) were 10.8, 6.2 months, the median overall survival (OS) were 25.6, 18.6 months respectively.There were no statistical differences in the RR (x2 =0.287, P =0.592) and DCR (x2 =1.222, P =0.269) between the two groups.There were statistical difference in the PFS (x2 =6.041, P =0.014) and OS (x2 =11.245, P =0.001) between the two groups.The most common toxicities of the sunitinib group were diarrhea, fatigue, oral mucositis, nausea, vomiting, all these toxicities were mainly Ⅰ-Ⅱ degree, and could be well tolerated.The hand-foot syndrome rate of the sorafenib group obviously exceeded the sunitinib group (59.1% vs.25.0% , x2 =4.972, P =0.026).Conclusion Sunitinib has good efficacy in the first-line treatment of advanced renal cell carcinoma with less toxicity than sorafenib, so it is worthy of popularization.

Objective To compare different equations for estimated glomerular filtration rate (eGFR) in patients with chronic kidney disease (CKD).Methods Hospitalized patients with CKD from the nephrology department of the First Affiliated Hospital of Nanjing Medical University (Jiangsu Province Hospital) were recruited between December 2014 and May 2015.The calculations of eGFR and 24 h creatinine clearance rate (Ccr) were accomplished in three days after admission.The eGFRs were calculated separately using the 24 h creatinine clearance rate adjusted by the standard body surface area (Ccr_BSA),Cockcroft-Gault equation adjusted by the standard body surface area (eCcr_BSA),CKD-EPI creatinine equation (EPI_Cr),CKD-EPI cystatin C equation (EPI_CysC),CKDEPI creatinine-cystatin C equation (EPI_Cr_CysC),simplified MDRD (MDRD) and China MDRD equations.The EPI_Cr_CysC equation was used as the standard and the precision and accuracy of the other six equations were compared and analyzed.Results A total of 403 CKD participants were enrolled in the study,with 228 male patients and a mean age of (54.9± 18.4) years.The main primary diseases were chronic glomerulonephritis (43.7%) and diabetic nephropathy (13.2%).The median concentration of serum creatinine and cystatin C were 117.5 (69.7,242.4) μmol/L and 1.80 (1.13,3.31) mg/L,respectively.The median values of Ccr_BSA,eCcr_BSA,MDRD,China MDRD,EPI_Cr,EPI_CysC and EPI_Cr_CysC equations were 50.8 (21.1,96.2),51.9 (23.3,93.2),53.6 (23.0,97.4),52.2(22.4,94.1),53.2 (22.1,97.3),35.1 (15.4,67.0) and 49.1 (22.8,82.3) ml · min-1 · (1.73 m2)-1,respectively.There was well agreement among MDRD,China MDRD and EPI_Cr equations,while there were large differences between equations derived from CysC (EPI_Cr_CysC and EPI_CysC) and equations derived only from creatinine (EPI_Cr,MDRD,China MDRD,eCcr_BSA,Ccr_BSA equations).Compared with EPI_Cr_CysC equation (the reference equation),EPI_Cr equation showed the highest accuracy [percentage of other eGFR equation calculations that were > 30% of the reference equation calculations (1-P30),30.8%] while Ccr_BSA equation showed the lowest (1-P30,42.4%).EPI_CysC equation showed the highest precision [inter-quartile range (IQR) of the difference,11.7 ml·min-1 · (1.73 m2)-1] while Ccr_BSA equation showed the lowest [IQR of the difference,22.8 ml· min-1 ·(1.73 m2)-1].Conclusions The agreement among equations derived only from creatinine is better;while it exhibits some differences between equations with cystatin C and equations derived only from creatinine.The accuracy of EPI_Cr equation is second only to EPI_Cr_CysC equation and it is currently the most suitable eGFR equation for clinical popularization of renal glomerular function assessment.

Aims To extract,separate and identify the flavonoid constituents in Humulus Scandens and to ex-plore the relationship of monomers and alveolar fluid clearance (AFC)in mice in vivo.Methods Humulus scandens were extracted with alcohol and then isolated by the technology of Column and the structures were i-dentified by spectrometry.In vivo AFC was measured using bovine serum albumin protein assays affected by luteolin-7-O-β-D-glucoside (LGL ) and cosmsiin (AGL).Results The main constituents of flavanones
in Humulus scandens were LGL and AGL.Both of them could improve the AFC.Conclusion The AFCs of LGL and AGL,compared to the blank control group, increased which explains the effect of flavonoid constit-uents on removing edema and promoting water absorp-tion.

PurposeAcute lung injury/acute respiratory distress syndrome is a common severe disease, this paper aims to explore the pathological basis of diffuse comet-tail artifacts in rabbits with acute lung injury and evaluate the imaging value on pathological changes.Materials and Methods The bilateral anterior chest walls of the rabbits were divided into four zones, namely, left upper zone, right upper zone, left lower zone and right lower zone. The normal chest ultrasound images of the 6 rabbits were obtained. After oleic acid (0.1 ml/kg) was injected, the images of comet-tail artifact in the four lung zones were dynamically observed and stored for 1 hour. The chest ultrasound images were evaluated according to the ultrasound scores. The degree of pathological damage in each lung zone was assessed and analyzed in terms of the correlation with the ultrasound results.Results The animal model of acute lung injury with diffuse comet-tail artifacts was successfully made in all of the 6 rabbits. The main pathological changes of the animal model of oleic acid were diffuse pulmonary edema, congestion and congestive hemorrhage; necrosis was found in 4 rabbits. The area of pulmonary edema, congestion, and congestive hemorrhage increased gradually from top to bottom, and double diaphragm leaves were typical. A significant correlation was found between the ultrasound scores of comet-tail artifacts and the degrees of pathological damage (r=0.819,P<0.05).Conclusion The histological changes of chest diffuse comet-tail artifacts due to acute lung injury are pulmonary edema, congestion and congestive hemorrhage. The scope and density of diffuse comet-tail artifacts may indicate the degree of pulmonary parenchyma injury, which is important as reference to guide the treatment and prognosis.
