Recently,many researches showed that vitamin D was involved in the pathophysiological processes of cardiovascular diseases.The incidence of vitamin D deficiency was increased with aging,and might be associated with an increased prevalence of cardiovascular disease with aging.In this paper,the association of vitamin D with cardiovascular diseases and the possible mechanisms are reviewed.

Background The mitochondrial Na+/Ca2+exchanger, NCLX, plays an important role in the balance between Ca2+influx and efflux across the mitochondrial inner membrane in endothelial cells. Mitochondrial metabolism is likely to be affected by the activity of NCLX because Ca2+activates several enzymes of the Krebs cycle. It is currently believed that mitochondria are not only centers of energy produc-tion but are also important sites of reactive oxygen species (ROS) generation and nucleotide-binding oligomerization domain receptor 3 (NLRP3) inflammasome activation. Methods&Results This study focused on NCLX function, in rat aortic endothelial cells (RAECs), induced by glucose. First, we detected an increase in NCLX expression in the endothelia of rats with diabetes mellitus, which was induced by an injection of streptozotocin. Next, colocalization of NCLX expression and mitochondria was detected using confocal analysis. Suppression of NCLX expression, using an siRNA construct (siNCLX), enhanced mitochondrial Ca2+influx and blocked efflux induced by glucose. Un-expectedly, silencing of NCLX expression induced increased ROS generation and NLRP3 inflammasome activation. Conclusions These findings suggest that NCLX affects glucose-dependent mitochondrial Ca2+signaling, thereby regulating ROS generation and NLRP3 in-flammasome activation in high glucose conditions. In the early stages of high glucose stimulation, NCLX expression increases to compensate in order to self-protect mitochondrial maintenance, stability, and function in endothelial cells.

Porcine Reproductive and Respiratory Syndrome virus (PRRSV) is the etiological agent of Por- cine Reproductive and Respiratory Syndrome. We summarized the recent research progress on molecular bi- ology of PRRSV including the structure of genome, viral structural and Non-structural protein.

Objective To explore the clinic value and efficacy of color Doppler ultrasound guided percutaneous microwave/radiorequency thermoablation for secondary hyperparathyroidism. Methods Fifty-six cases of secondary hyperparathyroidism who came from nephrology department of Beijing Friendship Hospital in the period of September 2012 to September 2013 were treated by color Doppler ultrasound guided percutaneous microwave/radiorequency thermoablation. One hundred and thirty-eight glands underwent this treatment and were evaluated by contrast enhanced ultrasound before, during and after operation. The levels of serum parathyroid hormone (PTH) were measured before and at 1 week, 1 month, 6 months and 1 year after treatment. Results The whole 56 cases achieved 1 month follow-up and 34 cases and 12 cases achieved 6 months and 1 year follow-up, respectively. Two special cases had been excluded. The PTH levels of 54 cases were signiifcantly different between after and before treatment [(369.5±183.4) ng/L vs (1321.6±471.4) ng/L, t=10.727, P=0.000]. The PTH levels continued to fall at the ifrst week after treatment, but there was no statistical signiifcance between the ifrst week and the ifrst day after treatment [(324.6±172.8) ng/L vs (369.5±183.4) ng/L], while there was signiifcantly different between the ifrst week after treatment and before treatment [(324.6±172.8) ng/L vs (1321.6±471.4) ng/L, t=9.364, P=0.000]. The PTH levels increased from (324.6±172.8) ng/L to (332.5±164.9) ng/L at 1 week and 1 month after ablation, while there was no signiifcant difference.But there is signiifcantly different between 1 month after treatment and before treatment (t=11.348, P=0.000). The PTH level at 6 months after treatment [(205.2±136.3) ng/L] and 1 year after treatment [(177.1±171.5) ng/L] had signiifcant difference compared with the value before treatment (t=8.737, P=0.000; t=7.655, P=0.017). Conclusion Color Doppler ultrasound guided percutaneous microwave/radiorequency thermoablation can be considered as a feasible and effective nonsurgical alternative treatment for secondary hyperparathyroidism patients.

Vitexin, a naturally occurring flavone glycoside in plants, has many pharmacological effects, which is widely distributed in nature. This paper reviewed the research progress of the distribution of vitexin in the plant resources and its pharmacological effects, and summarized its application prospects, aiming to provide a useful reference for the development of vitexin-enriched plant resources.

AIM:To investigate the cause of blindness, except those caused by cataract, in Haimen city.METHODS:According to the WHO`s criteria of blindness, the blindness level was decided through ophthalmic tests by associate chief or chief ophthalmologists who were trained especially for disability evaluation.The analysis of the the leading cause were taken too.RESULTS:Totally 3 266 persons were blindness, in which 2 118 were first level blindness, 1 148 persons were second lever blindness, and 1 308 persons were male, 1958 were female.The leading cause of blindness were retina and uveitis diseases (31.58%), genetic diseases(23.47%), cornea disease(14.49%).CONCLUSION:The leading cause of blindness are retina and uveitis diseases, genetic diseases, cornea diseases in Haimen city of Jiangsu province.Early prevention and treatment should be strengthened to reduce the occurrence of blindness.

This study aims to establish an HPLC method for simultaneous determination of gastrodin and eight nucleosides and nucleobases components in Gastrodia elata. The separation was carried out on an Agilent Zorbax Bonus-RP (4.6 mm x 250 mm, 5 μm) column with a methanol-(0.04% acetic acid) water solution gradient elution program at a flow rate of 1.0 mL x min(-1). The column temperature was 36 degrees C, and the detection wavelength was 254 nm. The volume of injection was 20 μL. The nine components including gastrodin, cytosine, uracil, cytosine, adenine, thymine, uridine, guanosine and adenosine were well separated. The calibration curve was well linear in the range of 2.04-262.00 mg x L(-1), 0.20-24.67 mg x L(-1), 0.18-23.75 mg x L(-1), 0.20-25.83 mg x L(-1), 0.20-26.67 mg x L(-1), 0.16-20.00 mg x L(-1), 0.22-27.71 mg x L(-1), 0.20-24.29 mg x L(-1), 0.24-30.58 mg x L(-1), respectively, and the correlation coefficient was between 0.998 9-0.999 9. The average recovery of gastrodin and eight nucleosides and nucleobases were 96.4%-99.6%, RSD less than 2.7% (n = 6). The contents of gastrodin in all the seven Tibet cultured Gastrodia elata samples were over 2 mg x g(-1). Further, all samples contain higher contents of adenosine, guanosine, uridine and cytidine compared to low contents of cytosine, uracil, adenine and thymine. The established method is accurate, reproducible and suitable for the determination of gastrodin and eight nucleosides and nucleobases comppnents in Gastrodia elata.
