ABSTRACT

Objective To explore the effect of recombinant human tissue plasminogen activator(rt-PA) intravenous thrombolytic therapy combined with antiplatelet therapy on the recurrence of cardio cerebral vascular adverse events in patients with mild acute ischemic stroke (AIS).Methods From December 2015 to December 2017,74 patients with mild AIS treated in Shaoxing Central Hospital were selected in the research.According to the random number table method,the patients were divided into two groups,with 37 cases in each group.The control group received rt-PA intravenous thrombolysis,and the combined group was treated with antiplatelet therapy on the basis of the control group.The serum creatinine(SCr),alanine transaminase(ALT) and platelet count(PLT) were compared before and after treatment in the two groups,and the scores of the Barthel index scale and the modified Rankin scale were compared between the two groups.The incidence of cardiovascular adverse events in 3 months of the two groups was also recorded.Results There were no statistically significant differences in liver and kidney function indicators between the two groups before and after treatment (t =0.30,0.27,0.20,0.77,0.03,0.64,all P > 0.05).Before treatment,the Barthel index scale scores in the combined group and control group[(74.97 ±4.74)points,(61.95 ± 4.24) points] were significantly increased,and the increasing degree in the combined group was more significant than that in the control group(t =12.45,P < 0.05).The modified Rankin scale scores in the combined group and control group[(1.16 ± 0.37) points,(2.05 ± 0.45) points] were significantly decreased compared with those before treatment,and the reduction degree of the combined group was more significant than that in the control group(t =9.29,P < 0.05).The total incidence rate of bleeding events,cardiovascular events,cerebrovascular events and death events in the combined group(5.41%) was significantly lower than that of the control group(27.03%) (x2 =4.87,P < 0.05).Conclusion rt-PA intravenous thrombolytic therapy combined with antiplatelet therapy can effectively improve the nerve function and daily activity of patients with mild AIS.It can also effectively reduce the incidence of cardiovascular and cerebrovascular adverse events,and thus help to improve the prognosis and improve the quality of life.Therefore,it has good clinical application value.

ABSTRACT

Objective Broth dilution method was used as a reference method to observe the capability of Kirby-Bauer disc diffusion assay(K-B)for correcting automated ampicillin susceptibility detection of He-mophilus influenzae(HI).Methods A total of 228 HI strains isolated were collected,broth dilution assay,K-B and automated microdilution broth test(ATB)were used to determine the susceptibility of HI to ampicillin. Analyze the essential agreements of the three methods and the correction of K-B to the errors of A TB. Results The essential agreement of K-B or ATB with broth dilution method were 77.19%,70.18% respec-tively,combination of K-B and ATB could make the essential agreement increase up to 86.0%,which was sig-nificantly higher than ATB(χ2=16.600,P=0.000).Major error of ATB(42.0%)was higher than that of K-B(10.0%)(χ2=13.306,P=0.001),but very major error and minor error showed no significant difference be-tween the two methods(χ2=1.208,P=0.272;χ2=1.182,P=0.227),meanwhile,76.19% of major error of ATB could be corrected by K-B.For the very major error of ATB,53.57% could be corrected by K-B.Howev-er,the corrective capability of K-B to minor error of ATB was relative low.Conclusion K-B test could correct some errors generated by ATB.For the β-lactamase negative strains which were judged as ampicillin resistance by A TB,K-B test should be used to correct the errors by ATB.Moreover,it is necessary to apply K-B to confirm am-picillin sensitivity of the β-lactamase positive strains which were judged as ampicillin susceptible by ATB.

ABSTRACT

Objective To investigate the immediate effects of lower limb with open chain weight-adding on joint position sense and gait symmetry in stroke patients. Methods From January, 2016 to January, 2017, 39 stroke patients were included. Their joint position sense and gait symmetry were compared before and after weight-adding. The joint position senses of active reproduction of active positioning (ARAP) and passive reproduction of passive positioning (PRPP) were assessed during lower limb straight leg raise. The gait symmetry was also as-sessed and three indexes were recorded including the symmetry of foot rotation angle, step length and percentage of single leg support phase. Results After weight-adding, the position sense of PRPP did not improve (t=0.832, P=0.832), nor of the symmetry of foot rotation an-gle (t=-0.704, P=0.483) and percentage of single leg support phase (t=0.381, P=0.702);the position sense of ARAP improved (t=3.158, P=0.011), as well as the symmetry of step length (t=2.022, P=0.041). Conclusion The lower limb with open chain weight-adding could im-prove the active joint position sense and symmetry of step length.

ABSTRACT

The inter-species differences of estradiol metabolism were investigated in human, Beagle dog and rat liver microsomes by comparing enzyme kinetics of parent drug and the formation of its major metabolites. The incubation systems of estradiol with liver microsomes of the three species were optimized in terms of estradiol concentration, microsomal protein content and incubation time. The concentrations of estradiol and its metabolites were measured by LC-MS/MS method. The t1/2, CLint, CLh, Km and Vmax of estradiol incubated with male human liver microsomes were 40.02 +/- 8.32 min, 41.39 +/- 6.57 mL x min(-1) x kg(-1), 13.81 +/- 12.36 mL x min(-1) x kg(-1), 26.8 +/- 6.99 micromol x L(-1) and 0.75 +/- 0.92 micromol x L(-1) x min(-1), respectively. The corresponding parameters of female human were 44.71 +/- 10.21 min, 29.85 +/- 8.97 mL x min(-1) x kg(-1), 0.01 +/- 0.68 mL x min(-1) x kg(-1), 44.2 +/- 7.73 micromol x L(-1) and 1.27 +/- 4.41 micromol x L(-1) x min(-1), that of male dog were 21 +/- 7.33 min, 165.53 +/- 29.33 mL x min(-1) xkg(-1), 26.01 +/- 8.39 mL x min(-1) x kg(-1), 19.5 +/- 7.34 micromol x L(-1) and 1.6 +/- 0.65 micromol x L(-1) x min(-1), that of female dog were 25.5 +/- 5.32 min, 135.11 +/- 42.34 mL x min(-1) x kg(-1), 0.24 +/- 3.18 mL x min(-1) x kg(-1), 8.33 +/- 6.32 micromol x L(-1) and 0.51 +/- 2.15 micromol x L(-1) x min(-1), that of male rat were 5.11 +/- 3.84 min, 485.63 +/- 36.52 mL x min(-1) x kg(-1), 49.57 +/- 15.29 mL x min(-1) x kg(-1), 62 +/- 13.74 micromol x L(-1) and 19.16 +/- 9.67 micromol x L(-1) x min(-1), and that of female rat were 7.0 +/- 3.69 min, 354.82 +/- 33.33 mL x min(-1) x kg(-1), 8.04 +/- 3.23 mL x min(-1) x kg(-1), 35.38 +/- 7.65 micromol x L(-1) and 8.39 +/- 4.91 micromol x L(-1) min(-1), respectively. There were nine metabolites detected from all the three species, but the relative amounts of the metabolites generated were different in three species. The results indicted that the major phase I metabolic pathway of estradiol was similar in the liver microsomes from all the three species. However, the inter-species differences were found in the view of relative amounts of the metabolites as well as the metabolic characteristics of estradiol in liver microsomal incubation.

ABSTRACT

Objective To study the level and structure of intelligence in children with benign epilepsy of childhood with centrotemporal spikes(BECT)and investigate factors affecting their intelligence.Methods Congitive skills such as intelligence quotient(IQ),phonological test and morphological test,were evaluated in 47 children with BECT,and the results were compared to a control group of 30 children matched for gender,age,level of education and family background.The effects of age of onset,disease course,seizure frequency,seizure type,location of spike,and spike and wave index(SWI)on the level and structure of intelligence were also analyzed.Results The total IQ score was slightly lower in children with BECT(104.20±12.34)when compared to the control group of normal children(109.45±15.01),but the difference was not significant.There was no difference in performance IQ scores between BECT and normal children.BECT children had a lower verbal IQ score(90.67±18.40)when compared to the control group(98.17±13.18,t=3.431.P<0.05).Analyses of verbal subtests revealed significant differences between BECT and normal children in vocabulary and similarities(5.97±2.95 vs 8.51±3.67 and 4.85±3.02 vs 6.95±3.07,respectively,t value were 2.365 and 2.096,both P<0.05).The differences between BECT and normal children were also significant in phonological test and morphological test (12.56±2.3 vs 16.78±3.72 and 22.35±3.25 vs 24.15±5.28,respectively,t=2.478 and 2.770,both P<0.05).SWI was negatively correlated with verbal IQ,vocabulary,similarities,phonological test and morphological test(r=-0.305--0.838,P<0.05).Age of onset,disease course and seizure frequency were not correlated with verbal IQ,phonological test and morphological test.The level of intelligence was not different among children with left hemispheric foci,fight hemispheric foci or bilateral foci.The level of intelligence Was similar between children with partial seizures or secondarily generalized seizures.Conclusions Children with BECT have normal level of intelligence,but the structure of intelligence is abnormal with retardation of their language ability.SWI affects the language ability in children with BECT,but age of onset,seizure type and location of spike do not influence their language ability.
