Objective To investigate the influence of the liver failing to convey and disperse on space navigation aging.Methods High and low neuroticism subjects screened by Eysenck personality questionnaire were included in liver failing to convey and disperse group and liver controlling conveyance and dispersion group,respectively.The two groups were then divided into youth and elderly groups based on age.Finally,spatial navigation task was conducted to record and analyze behavioral(reaction time and accuracy)and EEG data(amplitude and latency of P2 and N2 components)of all the four groups(30 subjects each group).Results Compared with liver controlling conveyance and dispersion group,the accuracy in subjects with liver failing to convey and disperse decreased significantly(P<0.001)and reaction time was prolonged significantly(P<0.05).The interaction effect between age and liver regulation status showed a marginal significant difference(P=0.078).The accuracy of elderly people was lower than that of youth people(P=0.002)for liver failing to convey and disperse subjects,while there was no significant difference between the two groups for subjects with liver controlling conveyance and dispersion.The P2 amplitude in the elderly group was significantly smaller than that in the youth group(P=0.027).The amplitude of P2 in group of liver failing to convey and disperse was significantly smaller than that in group of liver controlling conveyance and dispersion(P=0.042).The interaction effect of P2 amplitude between age and liver regulation status showed a marginal significance(P=0.073).For youth subjects,the P2 amplitude in group of liver controlling conveyance and dispersion was significantly larger than that in group of liver failing to convey and disperse(P=0.007),while there was no significant difference in P2 amplitude between the two groups for the elderly subjects.The N2 amplitude for tasks of allocentric frames of reference was significantly greater than that of egocentric frames of reference(P=0.024).Conclusion Liver failing to convey and disperse caused by long-term emotional disturbance accelerates spatial navigation aging,and selective attention feature inhibition disorder may be the underlying ERPs neuroelectrophysiological mechanism.

Objective To investigate the influence of the and mechanism of liver failing to convey and disperse on age-related changes in attentional search based on ERPs.Methods oddball attention search task was administrated to record and analyze behavioral and EEG data(N2pc、SPCN、N2pc-Ptc components)of 120 subjects.Results Compared with liver controlling conveyance and dispersion group,the accuracy in subjects with liver failing to convey and disperse decreased significantly(P<0.05).The elderly group had a lower accuracy(P<0.001)and a longer reaction time(P<0.001)compared to the young group.The N2pc amplitude in subjects with liver failing to convey and disperse was significantly greater than that in subjects with liver controlling conveyance and dispersion(P<0.05).The interaction effect of SPCN amplitude between age and liver failing to convey and disperse status was significant(P=0.024).And in the elderly group,SPCN amplitude in subjects with liver dysregulation was significantly smaller than that of liver controlling conveyance and dispersion(P=0.042).The N2pc-Ptc peak to peak amplitude interaction effect between age and liver regulation status was marginal significant(P=0.087),and in liver failing to convey and disperse group,N2pc-Ptc peak to peak amplitude of the elderly was significantly smaller than that of the young(P=0.008).Conclusion Attention search ability is impaired in the elderly with liver failing to convey and disperse,and the electrophysiological abnormalities,such as directed attention allocation,spatiotemporal dynamic cohesion and short-term memory maintenance,may be part of the mechanism.

Objective To investigate the clinical efficacy and safety of facilitated percutaneous coronary intervention(PCI)with half-dose recombinant staphylokinase(r-SAK)in patients with ST-segment elevation myocardial infarction(STEMI)who are expected to undergo PCI within 120 minutes.Methods From October 2021 to August 2022,a total of 200 STEMI patients in eight centers were included and randomly assigned in a 1﹕1 ratio to either r-SAK group or control group.Patients received loading doses of aspirin and ticagrelor and intravenous heparin and were randomized to receive an intravenous bolus of either 5 mg r-SAK or normal saline prior to PCI.The outcomes were set as ST-segment resolution(STR)at 60-90 minutes after PCI,the proportion and transition of pathological Q waves on the 5th day after PCI,and the proportion of high-sensitivity cardiac troponin T(hs-cTnT)peaking within 12 hours of onset.The safety outcome was major bleeding events defined as Bleeding Academic Research Consortium(BARC)≥type 3 bleeding during hospitalization.Results Compared with the control group,the r-SAK group had a higher proportion of STR≥70%within 60-90 minutes after PCI(58.3%vs.40.3%,P=0.009);a lower proportion of pathological Q waves(59.1%vs.74.1%,P=0.040);a lower rate of Q wave progression(14.8%vs.43.2%,P＜0.001);a higher rate of Q wave disappearance(12.5%vs.3.7%,P=0.027);and a higher proportion of hs-cTnT peaking within 12 hours of symptom onset[31/40(77.5%)vs.17/33(51.5%),P=0.027].Regarding the safety outcome,no significant difference in BARC≥type 3 bleeding was found between the two groups during hospitalization(P＞0.05).Conclusions For STEMI patients who were expected to undergo primary PCI within 120 minutes of symptom onset,the facilitated PCI with half-dose r-SAK significantly increased the proportion of STR≥70%at 60-90 minutes after PCI,reduced the formation of pathological Q waves,and shortened the time to peak hs-cTnT,without increasing the risk of bleeding,which should be an alternative reperfusion strategy worthy of further study.
