The antioxidation of Zea pollinium in rats was studied. Twenty four 5-month old Wistar rats were selected, and randomly divided into control group (basal diet) and bee pollen group (diet containing 10% bee pollen). After feeding with the diet for 10 weeks, the results showed that the MDA levels in serum and liver were 5.73 ?0.22nmol/ml and 0.1951 ? 0.0049nmol/mg protain respectively in the bee pollen group, obviously lower than those of the control group (8.23?0.21nmol/ml and 0.2497?0.0083nmol/mg protein) (p

Objective To identify mutations in the OSMR gene in a pedigree with familial primary cutaneous amyloidosis (FPCA).Methods Clinical data were collected from a pedigree with FPCA.Peripheral blood samples were obtained from the proband,his 19 relatives,and 50 unrelated healthy human controls.Genomic DNA was extracted from these blood samples,and subjected to PCR for the amplification of 18 encoding exons and their flanking sequences of the OSMR gene followed by DNA sequencing.Results A heterozygous missense mutation c.2081C ＞ T,which leads to the substitution of proline by threonine at position 694,was detected in the OSMR gene of the proband and his affected relatives,but not in unaffected relatives or healthy controls.Conclusion The heterozygous mutation p.P694L in the OSMR gene may cause the clinical phenotype of FPCA in this family.

Objective:To explore the efficacies of single-center pediatric transplantations and discuss the current problems.Methods:From July 2007 to September 2019, the clinical data of 202 children (aged ≤17 years) undergoing renal transplantation were reviewed. And their perioperative complications, transplantation outcomes and patient/kidney survival were analyzed.Results:The most common perioperative complication was delayed graft function (DGF)( n=24, 11.9%), recurrence of renopathy ( n=8, 4.0%) and acute rejection ( n=21, 10.4%). The major causes of death and graft failure were lung infection ( n=9, 4.5%) and rejection ( n=11, 5.4%). Perioperative serum creatinine decreased progressively from (816.1±303.1) μmol/L preoperatively to (62.7±20.6) μmol/L at Month 3 post-operation. The value of eGFR were (166.8±37.3), (135.1±29.0) and (109.9±31.1) ml/(min·1.73 m 2) at Year 1/3/5 post-operation respectively. The survival rates were 96.7%, 96.3%, 94.1%, 93.5%, 94.1% and 90.7% at Year 1/3/5 post-operation respectively. No difference existed in human/kidney survival rate between LD and DD groups at Year 1/3/5 post-operation ( P>0.05) and transplantation outcomes were excellent. Conclusions:Effective and successful outcomes have been achieved at our center. And further optimizations are required for resolving various problems.
