Objective To investigate the therapeutic effect and mechanism of non-mitogenic acid fibroblast growth factor 1( NMFGF1) on diabetic cardiomyopathy ( DCM) by using PEG-modified nano-liposomes combined with ultrasound-targeted microbubble destruction technique ( UTMD ) . Methods The NMFGF1 loaded PEG-modified nano-liposomes were prepared by a water-in-water emulsion method and their quality inspections were also investigated. Type 1 diabetes animal model was induced by intraperitoneal injection of streptozotocin ( 70 mg/kg) in male SD rats. The diabetic rats were raised twelve weeks after the diabetes model was established and DCM rats were selected by ultrasonic heart function examination. After two weeks of intervention, all rats were kept for another two weeks and then underwent transthoracic echocardiography examination. The rats were sacrificed and myocardial tissue was obtained to quantify myocardial collagen fraction ( CVF ) and cardiac myocyte apoptotic index by Sirius red staining and TUNEL staining. Results NMFGF1-loaded PEG-nano-liposomes showed a good morphology and 90.3%± 1.4% NMFGF1 encapsulation efficiency. Compared with DCM group, NMFGF1group, and NMFGF1-PEG-nano-liposomes group, NMFGF1-loaded PEG-nano-liposome plus UTMD group showed increased left ventricular end diastolic diameter (LVIDd) [(7.36±0.42) vs (5.75±0.24), (6.64±0.27), (6.72±0.24)mm, all P<0.05]and leftventricularfractionshortening(LVFS) [(50±3) vs (33±2), (44±5), (43±3)mm, all P<0.05], and decreased left ventricular posterior wall thickness (LVPW) [(1.65±0.07) vs (1.89±0.08), (1.73±0.11), (1.73 ±0.07) mm, all P<0.05], with decreased CVF and apoptotic index(all P<0.05). Conclusion PEG-nano-liposomes combining with UTMD technique has a greater translational potential in the delivery of NMFGF1 for the treatment of DCM by attenuating oxidative stress-induced injury and may provide a promising strategy for treating diabetes cardiomyopathy.

[Abstract] Objective: To evaluate the expression level of FOXD1 in glioma tissues of different grades, and to investigate the correlation between the expression of FOXD1 and the prognosis of glioma patients. Methods: The tumor tissues were collected from 40 glioma patients, who received surgical treatment in the neurosurgery department of the First Hospital of China Medical University from September 2014 to February 2015; Seven non-tumor tissues obtained from patients underwent internal decompression for traumatic brain injury were used as controls. The FOXD1 expression in glioma and non-tumor brain tissues was analyzed by qRT-PCR and IHC, and the correlations between clinical pathological features of glioma patients and FOXD1 expression level were analyzed. Furthermore, the Kaplan-Meier method was used to analyze the relationship between FOXD1 expression and survival time of patients. In addition, the expression of FOXD1 in glioma tissues and its relationship with patients’prognosis were confirmed by the data from GEO (GSE4290, GSE2223) and Rembrandt database. Results: qRT-PCR showed that the FOXD1 mRNA expression in glioma tissues of WHO grade IV was significantly higher than that of non-tumor brain tissues and glioma tissues of WHO grade II (P<0.01). German immunohistochemical score (GIS) was used to evaluate the immunohistochemical staining intensity, and the relationship between FOXD1 expression and clinical pathological features was analyzed. The results showed that FOXD1 in glioma tissues was related to WHO phathological grade level (χ2=11.73, P<0.01). There was statistically significant difference between the survival time of FOXD1 high expression group and FOXD1 low expression group (P=0.043). The data from GEO data base (GSE4290, GSE2223) and Rembrandt datasets showed that glioma tissues have a higher FOXD1 mRNA expression level than normal brain tissues, and the elevated expression of FOXD1 mRNA was negatively associated with the survival time of glioma patients. Conclusion: FOXD1 was highly expressed in glioma tissues, and the expression level of FOXD1 was increased as the pathological grade increases. The elevated expression of FOXD1 was related with the poor survival of glioma patients.

Objective To investigate the role of TNSALP gene detection in prenatal diagnosis of HPP. Method The clinical data and the results of complete exon sequencing of TNSALP gene in one neonate with low alkaline phosphatase (HPP) were analyzed retrospectively. Peripheral bloods from his family members were collected. The amniotic fluid cell in fetuses at 17 weeks was tested for candidate gene mutations by Sanger sequencing. Results Mainly manifestations in 6-day-old baby were multiple fractures, limb shortening and bending and dyspnea. He died of respiratory failure 9 days after birth. The serum alkaline phosphatase was decreased and serum calcium was decreased slightly; serum phosphorus, serum 25 hydroxyvitamin-D and parathyroid hormone were normal. X-ray showed that the whole body bone was very poorly mineralized, and the long diaphysis was enlarged with shape of a cup at the end and multiple fractures existed. Gene sequencing revealed a complex heterozygous missense mutation in the TNSALP gene, including the heterozygous missense mutation c.542C>T in exon sixth causing 181st amino acids changed from serine to leucine (p.S181L), and tenth exon heterozygous missense mutation in c.1016G>A causing 339th amino acid changed from glycine to glutamic acid (p.G339E). The parental phenotypes were normal. The c.542C>T mutation is inherited from his father and the c.1016G>A mutation is inherited from his mother. These two mutations were not detected in the fetus. Conclusion TNSALP gene analysis can be applied to the diagnosis and prenatal diagnosis of HPP.
