ABSTRACT
Purpose To investigate the multi-slice spiral CT (MSCT) features ofchromophobe renal cell carcinoma (CCRC),renal oncocytoma (RO) and clear-cell renal cell carcinoma (CCRCC) for the improvement of its diagnostic accuracy.Materials and Methods The MSCT data of 15 CCRC cases,8 RO cases,and 29 CCRCC cases confirmed by surgery or pathology at Dong H ua Hospital from October 2012 to April 2016 were retrospectively studied.The CT signs of different tumors were compared.Results Most CCRCC cases had cystic degenerations,which showed significant difference with CCRC and RO cases (P＜0.05);RO cases were found mostly with star-shaped scars,which had significant difference with CCRCC cases (P＜0.05);the enhanced scanning showed most of CCRC were enhanced homogeneously,which presented significant difference from CCRCC (P＜0.05).The lesion-kidney-ration (LKR) of CCRCC at cortical phase,parenchymal phase or excretory phase was significantly different from that of CCRC (P＜0.05);the LKR of CCRCC at cortical phase was significantly different from that of RO (P＜0.05);the LKR of CCRC at the three phases were all significantly different from that of RO (P＜0.05).The average △ LKR value of CCRCC was significantly different from that of CCRC and RO (P＜0.05);there was a certain degree of difference distribution of their △ LKR among the three kinds of cases.Taking CCRCC as object,when the LKR at cortical phase was 0.693 or △ LKR was 0.068,the sensitivity reached 93.3％ and the specificity reached 72.2％ or 88.9％ respectively in evaluating the differential diagnosis of CCRC and RO.Taking RO as object,when the LKR was 0.656 at cortical phase or was 0.595 at parenchymal phase,the sensitivity reached 83.3％ and 91.7％ respectively,and the specificity was 75.0％ and 58.3％ respectively,in evaluating the differential diagnosis of CCRC.Conclusion Enhanced MSCT at different phases,especially the calculation of LKR and △ LKR value,can benefit the diagnosis of CCRC,RO and CCRCC.
ABSTRACT
Objective To investigate folic acid combined with Qizhi Weitong granule on serum gastrin, sIL-2R and immune function in chronic atrophy gastritis patients of Hp positive.Methods 46 cases with Hp positive chronic atrophy gastritis were selected and randomly divided into two groups according to different treatment, 23 cases in each group.The control group were given folic acid tablet on the basis of conventional treatment, and the experimental group were treated on the basis of control group combined with Qizhi Weitong granule.The patients in two groups were all treated for three months.Serum gastrin, sIL-2R and T cell subsets levels were detected after treatment.ResuIts Compared with control group after treatment, the serum gastrin level of experimental group was higher (P<0.05), sIL-2R level was lower (P<0.05), CD4 +T, CD4 +T/CD8 +T were higher (P<0.05), and CD8 +T level was lower ( P<0.05 ) .ConcIusion Folic acid combined with Qizhi Weitong granule could significantly increase serum gastrin and CD4 +T level and reduce sIL-2R and CD8 +T level in chronic atrophy gastritis patients of Hp positive, as a guidance for clinical.
ABSTRACT
To evaluate the effects of supplemental probiotics and xylo-oligosaccharide on performance,digestive enzyme activities,blood index and intestinal microflora.Two hundred and forty crossbred early weaned PIC piglets with an average initial weight of (6.83 + 0.9) kg,weaned at (21 ± 2) d of age,were divided into four groups.Control Ⅰ (positive diet,with no probiotics and xylo-oligosaccharide but more fish meal,whey powder and little soybean meal),Control Ⅱ (negative diet,with no probiotics and xylo-oligosaccharide but less fish meal,whey powder and more soybean meal),Negative diet + 0.035 % probiotics,negative diet + 0.002% xylo-oligosaccharide.The results of theses studies suggested that whey powder and fish meal from 5.50% to 2.50%,soybean meal from 22.50% to 26.50% could result in decreasing of alimentary canal enzyme activity,blood sugar,total serum protein and the quantities of Bacillus in appendix(P<0.05),and raising of serum urea nitrogen,the quantities of Escherichia coli in appendix,diarrhea indexes and Feed/Gain(P<0.05).Addition of probiotics and xylo-oligosaccharide could significantly improve the activities of alimentary canal protein,lipase and amylase(P<0.05),decrease Feed/Gain and the levels of blood sugar and decrease the levels of serum urea nitrogen and improve protein equilibrium in blood and energy metabolism.The quantities of bacillus were improved,Escherichia coli were decreased in appendix(P<0.05).Diarrhea indexes were decreased(P<0.05).Whether adding probiotics and xylo-oligosaecharide or not could not affect ADG and ADFI (P>0.05).Addition of probiotics and xylo-oligosaccharide could improve digestive function,beneficial microbial population of post-alimentary canal,Feed/Gain and prevent the diarrhea of piglets.
