Epigallocatechin-3-gallate [EGCG] inhibits 3-hydroxy-3-methylglutaryl-CoA reductase in the presence of glycerol

The inhibition of 3-hydroxy-3-methylglutaryl CoA reductase [HMGCR] is considered able to decrease serum cholesterol levels and dramatically reduce the risk for cardiovascular and cerebrovascular diseases. The statins, competitive inhibitors of HMGCR, have been employed to control hypercholesterolemia. But their side effects, especially their safety of long-term administration have attracted great attention. Therefore, there is still an urgent requirement for the development of safer inhibitors of HMGCR with less serious side effects. In this study, we cloned and purified the catalytic domain of human HMGCR [delta HMGCR], and applied the method of Ultra Performance Liquid Chromatography [UPLC] to assay delta HMGCR activity and screen its inhibitors from natural products. The results indicated that EGCG can inhibit delta HMGCR in the presence of some glycerol in vitro and can decrease cellular total cholesterol in HepG2 cells. As a consequence, it is promising to put EGCG into the development of hypolipidemic health product

Hand-foot-mouth disease pathogen separation and EV71 VP1 gene analysis in Sanmenxia City, Henan Province, China / 病毒学报

The aim of this study was to understand the enterovirus types and biological features of pediatric cases of HFMD in Sanmenxia City during 2011, and compare the latter to a cohort of healthy children. Stool samples of 55 cases of HFMD and 60 healthy children were collected for the isolation and identification of enteroviruses using RNA extraction and real-time RT-PCR assays. EV71 and CA16 were identified by nucleotide sequencing using virus-specific VP1 primers; for the other enteroviruses, 012/011 and 008/013 primers were used for amplification and sequencing. The results were analysed by sequence alignment with known sequences, and the characteristics of the EV71 VP1 gene were also analyzed. The detection rates for enteroviruses in cases of HFMD and healthy children were 52.73% (29/55) and 18.33% (11/60), respectively. Among these, there were 22 cases of EV71, four cases of CA16 and three cases of other enteroviruses in the cases with HFMD. Eleven healthy children had intestinal viruses, of which nine were Coxsackie B virus strains (81.82%, 9/11). Gene sequencing of the 19 EV71 strains illustrated that they were all subgenotype C4a, but the evolutionary tree showed an obvious clustering between cases from Lingbao City and Lushi County. This study demonstrates that the EV71 subgenotype C4a and CA16 strains were the most common cause of HFMD in Sanmenxia City in 2011, and that Coxsackie B strains were prevalent in healthy children. This finding may indicate that there is a widespread source of recessive infection in the community.

Protective effects of edaravone on diffuse brain injury in rats / 世界急诊医学杂志（英文）

BACKGROUND: Edaravone can alleviate brain injury and improve neurological functions and symptoms. This study aimed to investigate the effect of edaravone on the p38Mitogen-activated protein kinases/Caspase-3 (p38MAPK /Caspase-3) pathway after diffuse brain injury (DBI) in rats. METHODS: DBI models were established according to the description of Marmarou's method. A total of 250 rats were divided (random number) into four groups: control group (CG, n=45), model group (MG, n=77), low-dose edaravone group (n=67, dosage 5 mg/kg) and high-dose edaravone group (n=61, dosage 10 mg/kg). After 1, 6, 24, 48, and 72 hours after injury, brain tissues were collected. The changes of neuron morphous in the hippocampal region were observed through Nissl staining. The expression levels of phosphorylated p38MAPK and caspase-3 were detected by immunohistochemistry and Western blotting respectively. Learning and memory function were tested with Morris water maze from the 3rd to 7th day after injury. RESULTS: Some neurons had histopathologic changes of necrosis and apoptosis in the model group compared with the control group. The phosphorylated p38MAPK expressions increased at 1, 6, 4, and 48 hours (P<0.05), but no significant difference was observed at 72 hours (0.54±0.19 vs. 0.40±0.14, P>0.05). Caspase-3 expressions increased at 6, 24, 48, and 72 hours respectively (P<0.05), but there was no significant difference at 1 hour (0.59±0.29 vs. 0.40±0.17, P>0.05). From the 3rd to 6th day during the Morris water maze test, the latency to find the platform was significantly prolonged (P<0.05) and times of rats crossing the platform was decreased on the 7th day (2.28±1.18 vs. 8.20±1.52, P<0.05). The phosphorylated p38MAPK expressions decreased at 6, 24 and 48 hours respectively in the low dose edaravone group compared with the model group (P<0.05), whereas no significant difference was seen at 1 hour (1.66±0.80 vs. 1.85±0.86, P>0.05). Caspase-3 expression decreased at 6, 24, 48, and 72 hours (P<0.05). The latency to find the platform was significantly shortened (P<0.05), and times of rats crossing the platform increased (4.17±1.15 vs. 2.28±1.18, P<0.05). The above mentioned parameters changed more significantly in the high-dose edaravone group than in the low-dose edaravone group. CONCLUSION: Edaravone can alleviate brain tissue damage after DBI, inhibit p38MAP signal activation after early injury, reduce the expression of caspase-3, and promote the recovery of neurological function in the late period.

Objective To compare the diagnostic value of myocardial perfusion imaging (MPI) and 64 multi-slice spiral CT (64-MSCT) for coronary artery disease (CAD). Methods Fifty-two patients with suspected or known CAD were included in the study. Each patient underwent both stress and rest MPI,MSCT as well as conventional coronary angiography (CAG) within 1 month. The stress and rest MPI were scored by a 5-grade criteria (0 ～ 4) based on 17 coronary artery segments. The difference between summed stress and rest scores ＞ 1 was defined as myocardial ischemia. Stenosis in one main vessel or one main branch of the main vessel ≥50% was defined as myocardial ischemia by MSCT. CAG was used as the reference for comparison. Statistical analysis was performed using SPSS 13. 0 software. Kappa value was used to test the accordance of MPI and MSCT results. X2 test was used to evaluate the difference between MPI and MSCT results. Results The patient-based sensitivity, specificity, positive and negative predictive values and accuracy of MPI and MSCT for the diagnosis of CAD were 86.7% (26/30), 77.3% ( 17/22),83.9% (26/31), 81.0% ( 17/21), 82.7% (43/52) and 83.3% ( 25/30), 86.4% ( 19/22), 89.3%( 25/28), 79.2% ( 19/24), 84.6% (44/52), respectively. The vessel-based sensitivity, specificity, positive and negative predictive values and accuracy of MPI and MSCT were 74.5% (38/51), 81.0% (85/105 ), 65.5% (38/58), 86.7% ( 85/98), 78.8% ( 123/156 ) and 90.2% (46/51 ), 88.6% ( 93/105 ),79.3 % (46/58), 94.9% (93/98), 89.1% ( 139/156), respectively. There was no statistically significant difference between MPI and MSCT for either patient or lesion-based diagnosis (X2 =0.44, 0.21, both P ＞0.05 ). 96.0% (24/25) patients with both abnormal MPI and MSCT positive were valified by CAG while 83.3% (15/18) patients with both MPI and MSCT negative were excluded by CAG. Conclusions Both MPI and MSCT are reliable diagnostic modalities for CAD. They also provide complementary diagnostic value to each other.
