Objective To analyze the values of anteroposterior diameter (APD) in fetal renal pelvis separation during different gestational weeks and in predicting the prognosis.Methods Totally 182 cases of fetal renal pelvis separation in the Second Affiliated Hospital of Soochow University were enrolled in this study between January 2013 and October 2015.All of them were followed up to 12 months after birth.The detecting gestational weeks of non-reversible renal hydronephrosis and values of fetal renal pelvis APD were analyzed.Results Among the 182 cases of fetal renal separation,46 cases were detected in the second trimester,136 cases were detected in the third trimester (bilateral renal pelvis separation occurred in 92 cases).During the follow-up,114 cases recovered in the fetal period and 52 cases recovered within 12 months after birth,finally,16 cases (8.8％,16/182) of them progressed to non-reversible renal hydronephrosis.Among the 16 fetus of non-reversible renal hydronephrosis,10 cases (62.5％,10/16) were detected in the second trimester,their values of APD were 7.4-11.5 mm and the average was (8.0± 1.5) mm;6 cases (37.5％,6/16) were detected in the third trimester,their values of APD were 13.6-14.8 mm and the average was (12.8±2.0) rmm.The values of APD in fetus who were detected in the second trimester were smaller than those in the fetus who detected in the third trimester and the prognosis in the fetus who were detected in the second trimester was worse than those in the fetus who were detected in the third trimester,the fetus (21.7％,10/46) who progressed to non-reversible renal hydronephrosis in the second trimester were more than the fetus (4.4％,6/136) who were detected in the third trimester.Conclusion Clinical following-up combined with the detecting gestational weeks of fetal renal pelvis separation and values of fetal renal plevis APD by prenatal ultrasound may be helpful in predicting their prognosis.

OBJECTIVE:To investigate the protective effect of the compatibilities of ginsenosides Rg1 and aconitine on myocar-dial cell of in vitro cultured heart failure model. METHODS:The myocardial cells of neonate rat were grouped into normal control group,model group,positive control group(Deslanoside injection,1×10-7 mol/L),ginsenosides Rg1 group(1×10-8 mol/L),acon-itine group (1 × 10-9 mol/L) or their compatibilities groups (1∶1,2∶1,1∶2,V/V). Except for normal control group,other groups were given 0.8%pentobarbital sodium to induce heart failure model of myocardial cells. After modeling,each group was given rele-vant medicine for 1 h,and then the activities of T-ATPase,Ca2+-Mg2+-ATPase,Na+-K+-ATPase in cells were all detected. The activi-ties of acyl carrier protein(ACP)and lactate dehydrogenase(LDH),and the contents of brain natriuretic party(BNP),TNF-α and total glycogen were measured in cell culture fluid. RESULTS:Compared with normal control group, T-ATPase and Ca2+-Mg2+-ATPase activities were decreased significantly in model group;meanwhile,Na+-K+-ATPase activity was increased signifi-cantly,and ACP,LDH activities and BNP content in cell culture fluid were increased significantly(P<0.05). Compared with mod-el group,the activities of T-ATPase in treatment groups were increased significantly,while the activity of LDH in cell culture fluid was decreased significantly;when the volume ratio of ginsenoside Rg1 to aconitine was 2∶1,protective effect was the strongest;the activities of Na+-K+-ATPase in aconitine group and compatibility groups were all decreased significantly,with statistical signifi-cance(P<0.05). The activities of ACP and BNP in cell culture fluid were all decreased in treatment groups,but the content of to-tal glycogen in cells and the TNF-α content of in cell culture fluid had no change (P>0.05). CONCLUSIONS:Compatibility of ginsenosides Rg1 and aconitine can improve ATPase activities and membranous permeability,regulate BNP secretion and protect myocardial cell of heart failure model,especially the compatibility of ginsenosides Rg1 to aconitine of 2∶1 ratio.

To evaluate clinical effect and immunological mechanism of intravene ous immunoglobulin (IVIG) for the treatment of bronchiolitis induced by respirat ory syncytial virus (RSV) in infants, the levels of serum interleukin 6 (IL- 6), interleukin 8 (IL-8) and tumor necrosis factor-α (TNF -α) were determined before and after IVIG therapy in 26 cases with IVIG therapy, 30 cases with the conventional therapy and 40 cases as normal controls , respectively. The recovery time of the clinical signs and symptoms and duratio n of hospitalization were also compared between the IVIG group and the conventio nal group. The results showed that the levels of IL-6, IL-8 and TNF-α were significantly higher in two groups before treatment comparin g to normal infants. These cytokines tended to decrease after IVIG therapy altho ugh no significantly difference was observed between the IVIG group and the conv entional group. It was noticed that the recovery time of clinical wheezing and l ung signs were obviously shortened in the IVIG group comparing to the convention a l group (4.0±2.1 Vs. 5.2±1.4days; 5.4±1.5 Vs. 6.5±1.8days, P ＜0.001， P＜0.05). No significantly difference of hospitalization days w as observed between two groups (9±2.2 Vs. 10.3±3.1days, P＞ 0.05). It is concluded that cytokines involves in the pathogenesis of bronchiolitis ind uced by RSV in infants, and IVIG therapy can be helpful for the improvement of t he clinical situation. However, the inhibitory effect on the production of cytok ines seems not to be obvious when single　IVIG　therapy　is given at a dose of 0.25g/kg.
