Objective To investigate the prevention effect of curcumin loaded nano - liposomes on diabetic cardiomyopathy. Methods The curcumin-loaded nano-liposomes were prepared by Film dispersion and ultrasonic hydration technology and their quality inspections were also investigated.Sixty SD rats were randomly divided into normal control group,model control group,blank and curcumin-loaded nano-liposomes group ( n＝15). Diabetes model was induced by intraperitoneal single injection of STZ(70 mg·kg-1).After two weeks of STZ injection,the rats with model control were used for this study.The curcumin loaded nano-liposomes treatment group rats were treated with curcumin loaded nano-liposomes ( 5 mg·kg-1) via caudal vein administration for 12 weeks (three times a week).Rats of normal control group,blank nano-liposomes treated group and model control group were administrated equivalent volume of 0. 9% sodium chloride solution or blank nano-liposomes solution. After treatment for 12 weeks,the experimental animals underwent ultrasonic heart function examination.Then the rats were sacrificed and their hearts were arrested after saline perfusion. The myocardial cell collagen volume fraction ( CVF) and apoptosis index were detected. Results Curcumin loaded nano-liposomes showed good morphology and curcumin encapsulation efficiency ( 88. 37 ± 1.21) %with high stability and dispersibility. From the animal experiments, the evaluation indexes in curcumin loaded nano-liposomes treated group including LVIDd and LVFS were significantly higher than model control group and nano-liposomes treated group(P<0.05),and the LVPW,CVF and apoptosis index were significantly lower than model control group and nano-liposomes treated group(P<0.05). Conclusion Curcumin loaded nano-liposomes can improve the cardiac function of diabetic rats by reducing the fibrosis and apoptosis index of myocardial cells in diabetic rats, which could be used to prevent the diabetic cardiomyopathy.

OBJECTIVE To study the gene chip joint pyrosequencing technology in the newborn genetic deafness gene mutation screening, and provide a theoretical basis for the early diagnosis and prevention of genetic deafness. METHODS 2000 Neonatal EDTA umbilical cord blood was collected and genomic DNA (gDNA) was extracted. Microarray chip was used to detect four deafness gene at 9 mutation sites. And the positive result of gene chip detection was verified by pyrosequencing.RESULTS Among the GJB2 mutations, there were 1 case of 35delG mutation type, 3 cases of 176 del16 mutation type, 57 cases of 235del C mutation type, 9 cases of 299 del AT mutation type, 6 cases of GJB3 gene 538C>T mutation type. There were 5 cases of 1555A>G mutations and 1 case of 1494C>T mutations in mitochondrial 12S rRNA. There were 6 cases of 2168A>G mutation type and 23 cases of IVS7-2A>G mutations in SLC26A4. 103 cases of newborns carry the mutated gene in 2,000, the gene mutation rate is 5.15%. CONCLUSION All the four genes mutation at nine mutation sites are found in newborns with family history of non-hereditary deafness, and GJB2 gene mutation is common. The screening of genetic deafness in newborns is very important for early diagnosis and prevention of hereditary hearing loss. In particular, the diagnosis of mitochondrial 12S rRNA gene mutation can prevent the occurrence of deafness caused by drug use, for the genetic mutation of these carriers' health is of great significance.
