Chinese Journal of cardiovascular Rehabilitation Medicine 2015;24(1):24-26
Objective:To measure serum level of cystatin C (Cys C)in patients with essential hypertension (EH)and analyze its correlation with pulse pressure (PP).Methods:A total of 60 EH patients and 30 cases with normal physi-cal examination results were selected.According to PP level,EH patients were divided into PP>60mmHg group (n=29)and PP≤60mmHg group (n=31).Serum Cys C concentration was measured by latex particle-enhanced immu-noturbidimetric method in two groups,and the results were statistically analyzed.Results:Cys C level of PP >60mmHg group was significantly higher than that of PP≤60mmHg group,and the both groups were significantly higher than that of normal control group [(1.40±0.06)mg/L vs.(1.19±0.54)mg/L vs.(0.72±0.20)mg/L], P <0.05 all;linear correlation analysis indicated that Cys C level was positively correlated with PP (r =0.325,P <0.05)and systolic blood pressure (SBP,r = 0.399,P < 0.05),and PP was positively correlated with SBP (r =0.876,P <0.01)in EH group.Conclusion:Cys C level is positively correlated with PP in EH patients.Cys C level can be used as an early index detecting renal function damage caused by hypertension.
6.Spinal cord injury and MicroRNA:in vitro prefabrication of tissue-engineered spinal cord and repair of spinal cord injury
Chinese Journal of Tissue Engineering Research 2015;(2):267-271
BACKGROUND:In the whole world, spinal cord injuries caused by trauma lead to more than 180 000 people presenting with permanent impairment annualy. A large number of experiments have confirmed in recent years, under physiological conditions, microRNA has specific expression and plays an important role in the nervous system. OBJECTIVE: To discuss the changes in microRNA expression induced by injuries as wel as the pathophysiological significance in spinal cord injury, and to explore the development potential of microRNA in tissue-engineered and clinical repair of spinal cord injury. METHODS:A computer-based search of PubMed and Chinese Journal Database was performed for related articles published from January 2000 to December 2014 using the keywords of “SCI, microRNA, transcriptional control, clinical research progress” in English and Chinese. Finaly, 38 articles were included for result analysis. RESULTS AND CONCLUSION: Mechanical injury initialy triggers a series of complex secondary damages, including nervous, vascular and immune systems, which can influence the severity of spinal cord injury to a great extent. Secondary damage to the spinal cord is mainly attributed to the activation and deactivation of some specific genes associated with celular and biochemical mechanisms, such as cysteine aspartate specific protease (caspase) gene family, apoptosis related protein Fas and its ligand Fasl system, P53 gene, apoptosis related gene Bcl-2 family. Recent studies have proved that the functional activation of microRNA expression is the key to spinal cord injury. With the development of biological information engineering, studies and controling technologies associated with microRNA expression have been gradualy dominated, some clinical application based on microRNA technology has entered the clinical trial stage. It is believed that with the continuous development of technology and decrease of cost, permanent dysfunction due to spinal cord injury can be regulated and repaired through the microRNA technology at gene level in the future.

9.A novel single-sided groove target release biodegradable stent inhibits coronary artery intimal hyperplasia
Chinese Journal of Tissue Engineering Research 2017;21(26):4222-4227
BACKGROUND: Theoretically, a novel single-sided groove target release biodegradable stent can avoid drug-induced inflammation of the local vessel wall, reduce drug dose, decrease the likelihood of thrombosis, and relieve stenosis.OBJECTIVE: To evaluate the influence of the novel single-sided groove target release biodegradable stent on intimal hyperplasia in a healthy porcine coronary artery model.METHODS: Eighteen healthy pigs were randomly divided into three groups, bare metal stent group, Firebird metal stent group and Firehawk stent group, which were implanted with L605 cobalt chromium alloy bare metal stents and L605 cobalt chromium alloy non-biodegradable rapamycin-eluting stent and L605 cobalt chromium alloy biodegradable rapamycin-eluting stent, respectively. Two same stents were implanted into the left anterior descending artery and the right coronary artery of each pig, respectively. After 1 and 3 months of follow-up, coronary angiography was performed,and the pigs were killed to take coronary artery samples for detection of intima hyperplasia.RESULTS AND CONCLUSION: At 1 and 3 months after stent implantation, no stenosis, thrombosis and aneurysm occurred in the three groups shown by the coronary angiography; the lumen loss was significantly lower in the Firebird metal stent group and Firehawk stent group than the bare metal stent group (P < 0.05), while there was no difference between the Firebird metal stent group and Firehawk stent group. Histopatologically, there was no coronary arterial tissue necrosis or luminal thrombosis in the three groups. Compared with the bare metal stent group, at 1 and 3 months after stent implantation, the neointimal area and the percentage of stenosis were significantly lower in the Firebird metal stent group and Firehawk stent group (P < 0.05), while the residual lumen area and internal elastic lamina area were significantly higher (P < 0.05). Additionally, there was no significant difference between the Firebird metal stent group and Firehawk stent group. Overall, the Firehawk stent that achieves the same clinical efficacy as the non-biodegradable rapamycin-eluting stent effectively inhibits intimal hyperplasia, and prevents stent restenosis after stent implantation.However, future investigations on the long-term effect are warranted.
