Objective To detect the level of plasma microRNA-1 (miR-1) in acute myocardial infarction (AMI) and compare the diagnostic values of it with that of cardiac troponin T (cTnT).Methods During 2011-05 to 2012-05,there were fifty-six plasma samples taken from patients with AMI and twenty-eight plasma specimens got from non-AMI controls were analyzed.The expression of plasma miR-1 was measured by quantitative reverse transcription-polymerase chain reaction (qRT-PCR),and the level of plasma cTnT was measured by using electrochemiluminescence-based methods on the Elecsys 2010 Immunoassay Analyzer.Then,the SPSS 16.0 was used for the statistical analysis.Data were presented as means ± standard deviation unless otherwise described.The differences about clinical characteristics between AMI patients and controls were tested using Student' s t-test or Fisher' s exact test.The Mann-Whitney test was conducted to compare the expression of microRNAs between the AMI patients and controls.The comparison of microRNAs expression between different intervals of AMI patients was done using Wilcoxon signed rank test.The receiver operating characteristic (ROC) curve was established to discriminate AMI patients from controls.Results The expression of plasma miR-1 was significantly increased in AMI patients (P ＜ 0.01) compared with healthy controls.The contents of the plasma miR-1 in AMI patients fell down nearly to the normal level at 14 days (P ＞ 0.05).There was no relevance between the expression of plasma miR-1 and the clinical characteristics of the study population (P ＞ 0.05).Moreover,ROC curve analyses demonstrated that miR-1 had the specificity and sensitivity for the diagnosis of early AMI,but was not superior to cTnT.Conclusions Our results showed that plasma miR-1 had the capacity in early diagnosis of early AMI,and can be biomarker for AMI,however,miR-1 is not superior to cTnT for the diagnosis of AMI.

OBJECTIVETo establish a method for detecting plasma concentration of corn polysaccharide iron complex (CPIC) and investigate its absorption, distribution and elimination in rats.

METHODSUsing radioactivity isotope tracing method, we detected the radioactivity of (59)Fe-CPIC in the plasma of rats at different time points by gavages of 3 doses (28.0, 14.0, and 7.0 mg/kg) (59)Fe-CPIC in SD rats. The pharmacokinetic parameters was obtained using DAS 2.0 program for analysis of tissue distribution and elimination of (59)Fe-CPIC.

RESULTSThe standard curve was linear within the range of 0.14-141 µg/ml (r=0.9999, n=5). The average recovery was 95% with a relative standard deviation no more than 15%. The pharmacokinetic parameters at 3 doses obtained, namely t1/2 and AUC (0-), were 214∓104, 231∓110, and 181∓81 min, and 1986.3∓513.3, 737.0∓467.0, and 315.1∓226.1 mg·min-1·L(-)1, respectively. (59)Fe-CPIC were detected in all the 13 tissues types examined and high radioactivity intensity was found in the gastrointestinal tract, hematogenic organs and other organs rich in blood. (59)Fe-CPIC was eliminated after intragastric administration primarily via the feces in rats.

CONCLUSIONThe method we established is easy and specific, and the pharmacokinetic parameters of (59)Fe-CPIC fit the two- compartment open model.

Objective:To evaluate the long-term safety, tolerability and efficacy of Lacosamide add-on therapy in Chinese children with partial-onset seizures.Methods:SP848 was a global multicenter single-arm study involving 60 Chinese children with partial-onset seizures with the age of 4-17 years who were managed by Lacosamide add-on therapy at seven hospitals across China from April 2018 to May 2019.After treatment with at least two kinds of anti-seizure medications simultaneously or sequentially, partial seizures were still poorly controlled and Lacosamide oral solution (syrup) or tablets were added.The minimum initial oral dose was 2 mg/(kg·d), and the maximum allowable dose was 12 mg/(kg·d)or 600 mg/d during the study period.The dose was adjusted according to the tolerance and seizure control level of partial-onset seizures children.Seizure frequency and the median percentage change in partial-onset seizures per 28 days from baseline to the final visit were recorded, including 50% responder rate and 75% responder rate.Results:A total of 60 Chinese children with the mean age of 9.18 (4.00-15.40) years were included in this interim analysis, involving 39 males and 21 females.The mean course of epilepsy was 5.04 (0.50-15.20) years.A total of 43 patients (71.7%) still have been treated.One patient (1.7%) has completed the 6-12 months of follow-up, and 14 patients (23.3%) have completed the follow-up for less than 6 months.The median change in the frequency of partial seizures every 28 days from baseline to the last visit was -2.91, with its median percentage as -25.46%, and the proportions of ≥50%, while ≥75% responder rate were 40.0% and 28.3%, respectively.A total of 52 patients (86.7%) had 265 treatment emergent adverse events (TEAE), 11 patients (18.3%) had 19 serious TEAE, 37 patients (61.7%) had 127 drug-related TEAE, and 11 patients (18.3%) had 16 TEAE leading to the discontinuation of the trial.The most common TEAE were upper respiratory tract infections (20 cases, 33.3%), followed by drowsiness (16 cases, 26.7%), dizziness (15 cases, 25.0%) and vomiting (13 cases, 21.7%). There were no abnormal changes in the electrocardiographic findings during the treatment.Conclusions:For Chinese patients with partial seizures who are older than the age of 4 years and poorly controlled by other drugs, Lacosamide is effective and well tolerated as an add-on therapy drug.The safety characteristics are consistent with those reported in children and adults.No new safety concerns are identified.

The aim of this study is to construct a bifunctional fusion protein, which can conjugate both human red blood cells and antibodies against classical swine fever virus (CSFV). We respectively amplified 2E8ScFv and mE2 genes from different recombinant vectors, in which 2E8ScFv gene is the single chain Fv gene against H antigen of human red blood cells, whereas mE2 gene is the main antigen coding region gene of CSFV E2 protein. We used overlap extension PCR to obtain an artificial fusion gene segment 2E8mE2 containing genes of Both 2E8ScFv and mE2, then ligated into the expression vector pET-DsbA and expressed in Escherichia coli BL21(DE3) PlysS host cells, after induced with IPTG the target fusion protein was successfully expressed and identified in inclusion bodies by SDS-PAGE and Western blotting. We purified the fusion protein and renatured it from inclusion bodies to obtain a native state of well biological activity. The Erythrocyte agglutination test results indicated that the fusion protein can conjugate both human red blood cells and antibodies of CSFV.

Objective:To explore the safety and effectiveness of medium-frequency electrotherapy for increasing the volume of the latissimus dorsi muscle.Methods:Fifteen adult New Zealand white rabbits were randomly divided into three groups, namely group A, group B, and group C, with 5 rabbits in each group. This was a self-control study, with the right latissimus dorsi muscle as the experimental group and the left latissimus dorsi muscle as the control group. The three groups corresponded to three different current intensity levels: 7.062 mA for group A (6th gear), 10.593 mA for group B (9th gear), and 14.124 mA for group C (12th gear). After the 12th, 24th, and 36th sessions of the experiment, ultrasonography was used to collect the thickness of the latissimus dorsi muscle. After the 36th electrostimulation, the latissimus dorsi muscle samples were collected to measure their in vivo muscle thickness and wet weight and were then sent for HE and MASSON staining.Results:After the 12th, 24th, and 36th electrostimulation sessions, ultrasonographic sampling in groups A and B showed an increase in the thickness of the right latissimus dorsi muscle compared to the left; for example, the thickness on the right of group B increased by 37.8%. The wet weight data collected after the 36th electrostimulation in groups A and B showed an increase in the right latissimus dorsi muscle compared to the left; for example, the wet weight on the right of group B increased by 5.04%.Conclusions:Different electrostimulation modes of medium-frequency therapy technology can induce muscle fiber thickening or atrophy. In this experiment, the 9th gear (10.593 mA) of medium-frequency therapy technology may be a suitable choice for inducing muscle fiber thickening, and the 12th gear (14.124 mA) may be a suitable choice for inducing skeletal muscle thinning.
