ABSTRACT
Objective:To investigate the effects of butylphthalide combined with ozagrel sodium on the National Institutes of Health Stroke Scale (NIHSS) score, activities of daily living (ADL) score, and coagulation function in patients with acute cerebral infarction.Methods:Ninety-four patients with acute cerebral infarction who were admitted to Gujiao Medical Group Central Hospital from January 2019 to November 2021 were included in this study. They were randomly assigned to undergo treatment with either ozagrel sodium (control group, n = 47) or butylphthalide combined with ozagrel sodium (observation group, n = 47) for 14 consecutive days. Before and after treatment, NIHSS score, ADL score, coagulation function (thrombin time, prothrombin time, D-dimer, activated partial thrombin time), bilateral middle cerebral artery blood flow status (mean blood flow velocity (Vm), resistance index, pulsatility index), brain tissue damage factor (brain natriuretic peptide, neuron-specific enolase, S100 β protein) and the incidence of adverse drug reactions were compared between the two groups. Results:Before treatment, there were no significant differences in NIHSS and ADL scores between the two groups (both P > 0.05). After treatment, the NIHSS score was significantly lower in the observation group than that in the control group [(8.70 ± 1.62) points vs. (9.45 ± 1.2) points, t = 2.51, P < 0.05]; the ADL score was significantly higher in the observation group than that in the control group [(65.15 ± 7.41) points vs. (61.20 ± 6.32) points, t = 2.78, P < 0.05]. Before treatment, there were no significant differences in thrombin time, prothrombin time, D-dimer, and activated partial thrombin time between the two groups (all P > 0.05). After treatment, thrombin time, prothrombin time, and activated partial thrombin time were significantly higher in the observation group than those in the control group ( t = 4.34, 3.00, 2.63, all P < 0.05). After treatment, D-dimer level in the observation group was significantly lower than that in the control group ( t = 3.39, P < 0.05). Before treatment, mean blood flow velocity, resistance index, and pulsatility index were similar between the two groups (all P > 0.05). After treatment, the mean blood flow velocity in the observation group was significantly higher than that in the control group ( t = 3.23, P < 0.05). The pulsatility index and resistance index were significantly lower in the observation group than those in the control group ( t = 2.14, 3.16, both P < 0.05). Before treatment, there were no significant differences in brain natriuretic peptide, neuron-specific enolase, and S100 β protein levels between the two groups (all P > 0.05). After treatment, brain natriuretic peptide, neuron-specific enolase, and S100 β protein levels in the observation group were significantly lower than those in the control group ( t = 3.09, 2.18, 3.33, all P < 0.05). There was no significant difference in incidence of adverse reactions between the observation and control groups [6.38% (3/47) vs. 2.13% (1/47), P > 0.05]. Conclusion:Butylphthalide combined with ozagrel sodium for the treatment of acute cerebral infarction can reduce neurological dysfunction and brain tissue injury, and improve coagulation function, hemodynamic state of the middle cerebral artery, and activities of daily life, without increasing adverse reactions.
ABSTRACT
Objective To compare the effects of closed reduction and interlocking intramedullary nail and percutaneous minimally invasive locking compression plate in treatment of tibial fractures.Methods 70 patients with tibial fractures were selected as research subjects,and they were randomly divided into the control group and the observation group according to the digital table,each group in 35cases.The control group was treated with closed reduction and interlocking intramedullary nail,while the observation group was treated with percutaneous minimally invasive locking compression plate.Then,the operation index,postoperative complications,treatment effect after treatment between two groups were compared.Results The operation time,fracture healing time,length of stay in the observation group were less than those in the control group[(70.37±11.06)min vs.(82.13±12.15)min,(3.02±0.61)month vs.(4.21±0.70)month,(13.39±3.02)d vs.(16.26±3.21)d](t=4.234,3.852,7.582,all P<0.05).The incidence rate of complication in the observation group was lower than that in the control group[14.28%(5/35) vs.51.42%(18/35)](χ2=10.943,P<0.05).The excellent rate in the observation group was statistically higher than that in the control group[94.28%(33/35) vs.74.28%(26/35)](χ2=5.285,P<0.05).Conclusion Closed reduction and interlocking intramedullary nail and minimally invasive percutaneous locking compression plate are successful in the treatment of tibial fracture,but interlocking intramedullary nail easily leads to delayed healing,complications and higher rate of surgery two times,while minimally invasive percutaneous locking compression plate can promote healing,curative effect is better.
ABSTRACT
Objective To determine chloramphenicol and metronidazolel in honey by isotope-labelled internal standards ultra performance liquid chromatography-mass spectrometry.Methods Samples were extracted with ethyl acetate solution,and cleaned up on a MCS cartridge.The target analytes were separated on a ZORBAX SB-C18column with gradient elution using a mobile phase made up of methanol and 5 mmol/L ammonium acetate solution (containing 0.05％ formic acid).Detection was carried out using positive and negative electrospray ionization and multiple reaction monitoring (MRM),and quantified with isotope internal standardmethod.Results The chloramphenicol and metronidazolel showed good linearity in the range of 0.05-5.00 ng/ml.The recovery at three spiked levels of 0.5,2.0 and 5.0 μg/kg were in the range of 79.3％-96.7％.The relative standard deviation (RSD) was 5.5％-14.8％.The limits of quantitation were 0.15 μg/kg,the limits of detection were 0.05 μg/kg.Conclusion The method is sensitive and accurate.It could be applied to the high-throughput analysis of chloramphenicol and metronidazolel.
