Metabolic bone disease in nephrotic syndrome(NS) are increasingly being renal physician's attention.As calcium binding protein and VitD binding protein losing with a large number of protenuria, the bone metabolic biochemical abnormalities had happened at the beginning of the onset of the nephrotic syndrome, and is further exacerbated by therapeutic high-dose or long course of glucocorticoids (GC) application.The main mechanism of the glucocorticoid-induced osteoporosis (GIOP) is for GC to inhibit the activity of osteoblasts and promote apoptosis of osteoblasts and formation of osteoclasts, resulting in secondary hyperparathyroidism,leading to increasing the risk of osteoporosis,slow growth and fracture,seriously harm to children's physical and mental health.The biomarkers of bone transform can prompt the NS with bone metabolic abnormalities early;vertebral body bone dual-energy X-ray absorptiometry bone mineral density detection is the best method and position to determine GIOP.As the most commonly used and effective means to prevent and control metabolic bone disease, calcium supplements and VitD were always taken when GC was treated for NS, even the dosage of GC was very low.So far, it is still lack of guideline of prevention and treatment of bone metabolic abnormalities in NS in children.

Objective To assess the prediction value of technetium-99m methoxyisobutylisonitrile(~(99)Tc~m-MIBI) for the effect of chemotherapy in small cell lung cancer (SCLC) patients. Methods Fifty-three patients with SCLC were divided into two groups according to the chest computed tomography (CT) examination, 39 patients in group A with complete or partial remission, and 14 patients in groups B with stable or progressive status. ~(99)Tc~m-MIBI was performed before chemotherapy. Following i. v. administration of 740 MBq ~(99)Tc~m-MIBI, SPECT imagings at 10 -30 minutes (early) and 2 -3 hours (delayed) were performed to obtain the uptake ratio of early phase tumor/normal lung tissue (ER) and the uptake ratio of delayed phase tumor/normal lung tissue (DR). The retention index (RI) was calculated as (DR-ER)/ ER × 100%. The differences of ER,DR and RI between the two groups were tested through t-test and rank sum test. Results ~(99)Tc~m-MIBI uptake was significantly higher in group A than group B: 2.33(SD:0.21) vs 2.02(SD:0.31) for the early ratio (ER) (t = -3.401, P<0.05) and 2.44(SD:0.19) vs 1.86 (SD :0.30) for the delayed ratio (DR) (t = - 6.724,P < 0.05). The median of RI in group A was signifi-cantly higher than that in group B (5.31% vs -9.26%,P <0.05). Conclusions ER,DR and RI of ~(99)Tc~m-MIBI SPECT may be helpful in predicting the response to chemotherapy in patients with SCLC.

Objective To investigate whether expression of XAF1 mediated by edenovirus vector AdS/F35 could induce apoptosis in pancreatic cancer cell line BxPC-3 and its possible mechanisms.Methods Preconstructed recombinant Ad5/F35-XAF1 virus and negative control Ad5/F35-Null was tranfected into BxPC3:the expression of XAF1 mRNA and protein before and after tranfection was,analyzed by semi-quantitative RT-PCR and Western blot.The expressions of proteins including Caspase-3,PARP,Caspase-8 and bcl-2 were detected by Western blots.Cell apoptosis was assessed by Annexin-v/PI and TUNEL staining.Results After Ad5/F35-XAF1 tranfection,XAF1 mRNA and protein expression significantly increased,and the difference was statistically significant when compared with control group and Ad5/F35-Null group(P＜0.05).The apoptosis rate was(19.90±3.09)%and(9.29±2.13)%,which was significantly different(P＜0.01)from those in the Ad5/F35-Null group[(6.72±0.7)6%,(2.73±0.51)%]or in the control group[(7.22±1.53)%,(1.56±0.47)%].The expression of Caspase-3,PARP and Caspase-8 significantly increased,but the expression of bcl-2 decreased.Conclusions XAF1 plays a major role in the apoptosis of pancreatic cancer that acts thriugh the activation of death receptor pathway and mitochondrial pathway of apoptosis.
