ABSTRACT
Objective:To summarize the management experience of helicopter medical transport in patients with critical heart disease, so as to provide reference for transport of patients with critical heart disease under the background of major natural disasters.Methods:The clinical and transport data of 36 critically ill cardiac patients in Fuwai Central China Cardiovascular Hospital from 16:30 on July 21 to 19:30 on July 22, 2021 due to historically rare heavy rainstorms were collected. All 36 critically ill cardiac patients were transported by helicopter. The safe transportation was implemented under the measures of quickly forming a transport leadership and coordination group, clarifying responsibilities and division of labor, doing a good job in the pretreatment of the patient's condition, pipeline assessment and mechanical circulation support (MCS) equipment, simulating and practicing the transfer process, improving the safety of the transfer implementation process, and effectively handing over with the target hospital. The gender, age, disease type, MCS, transport and outcome of patients were collected.Results:Thirty-six patients with cardiac critical illness were from adult extracardiac intensive care unit (ICU), adult cardiac care unit (CCU), children's CCU, comprehensive ICU and department of neurology. There were 24 males and 12 females; age (50.93±20.86) years old. There were 12 patients using respirator, 7 patients needing MCS, 2 of whom needed both extracorporeal membrane oxygenation (ECMO) and intra-aortic balloon pump (IABP), and 7 patients with post-cardiac surgery. The total distance of transportation of 36 patients was 1 638.4 km, the transit time was 10.5 hours, one way flight time of helicopter was about 8 minutes, and the average transport time per patient was about 17.5 minutes. The vital signs of 36 patients during transport were basically stable, without complications, and all of them reached the target hospital safely.Conclusion:Under the seamless connection of the rapid establishment of the transfer leadership coordination group, assessment of the patient's condition and pretreatment, the simulation of the transfer process, and the effective handover with the receiving hospital, the use of helicopter for medical transport for critically ill heart patients is feasible and safe, which can buy valuable time for saving patients' lives and further treatment.
ABSTRACT
@#Objective To explore the relationship between the polymorphism of catechol-O-methyltransferase (COMT) gene Val158Met site and depression in Parkinson's disease. Methods From June, 2016 to December, 2017, a cohort of 268 Chinese patients with Parkinson's disease and 252 age- and gender-matched healthy control subjects were recruited. The patients were divided into depression group (n=116) and non-depression group (n=152) according to Hamilton Depression Scale score. Their blood samples were collected and the polymorphism of Val158Met was carried out using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results No difference was identified in Val158Met polymorphism of genotype (χ2=0.78, P>0.05) and allele (χ2=0.25, P>0.05) among the depression group, the non-depression group and the control group. Conclusion The polymorphism of Val158Met in COMT gene does not contribute to the risk of depression in Parkinson's disease in China.
ABSTRACT
Objective To summarize the clinical and radiological features of DYT6 dystonia with mutations based on the data of our patient cohort as well as the report by others.Methods Clinical data of the 11 patients with DYT6 dystonia in Peking Union Medical College Hospital from June 2009 to May 2012 were retrospectively reviewed and analyzed.Clinical data included gender,onset age,initiative symptom of onset,the sites of involvemet,family history,etc.All patients were examined for brain MRI scan,6 patients were examined for DTI.Results Of the eleven gene-confirmed DYT6 dystonia patients,7 were male and 4 were female,with an onset-age ranged from 5 years to 36 years,the mean age of onset was 19.4years.Eight patients had a family history.There were 10 patients with early onset dystonia and only 1 patient with late onset dystonia.The most common site of onset was the neck (7/11),and the next was the right arm,1-5 body areas were affected at the time of neurological assessment,the average amount was 2.8,and the most frequently affected anatomical site was the neck (10/11),next came lower face,jaw and tongue.Among all the patients,6 patients presented with segmental dystonia,4 patients presented with focal dystonia,only 1 patient presented with generalized dystonia.All the patients with thanatos-associated protein domain-containing apoptosis-associated protein (THAP) domain affected had a family history,but the patients with the same mutant gene varied with clinical manifestation.Only 1 patients with non-THAP domain affected had a family history,but in most families,there were adult asymptomatic mutant gene carriers.Mutations within the THAP domain were associated with an earlier age of onset than non-THAP domain (17.3 and 21.8 years old).Routine MRI of all patients were normal and DTI of 6 patients showed that fractional anisotropy values in the bilateral sensorimotor area in DYT6 dystonia were reduced.A detailed description of a patient with TOR1A and THAP1 gene mutations was given.Conclusions Early onset dystonia is the main manifestation in patients with DYT6 dystonia in China.The most common site of onset is the neck,and the next is the right arm.The most frequently affected anatomical site is the neck,next come lower face,jaw and tongue.Laryngeal dystonia is absent.The patients with same mutant gene show high heterogeneity in the clinical manifestations,mutations within the THAP domain of THAP1 tend to manifest at an earlier age and higher penetration than mutations localized to non-THAP domain.Reduction of fractional anisotropy values indicates that the axonal integrity and coherence in the region of sensorimotor area is damaged in DYT6 dystonia.
ABSTRACT
Objective To observe the cerebral activation pattern in patients with cervical dystonia (CD) during finger movements and the changes caused by botulinum toxin injection by functional MRI.The possible etiological mechanism of CD and effect of peripheral botulinum toxin treatment on the level of central nerves system are investigated.Methods A designed functional MRI block with complex finger movements was applied and 11 patients with CD as well as 11 age and gender matched controls were scanned.Compare the activation pattern of CD pre/post treatment groups versus health controls.Evaluate and compare the symtom severity with Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS).Make a correlation analysis between activation pattern alteration and TWSTRS change in CD pre/post treatment groups.Results An reduced extent of activation in patients with CD was demonstrated compared to healthy controls in ipsilateral putamen,prefrontal cortex and contralateral somatosensory cortex to the direction of the head deviation,while an elevated extent of activation in ipsilateral precuneus and fusiform with statistic significance.At the time point of 4 weeks after botulinum toxin treatment patients showed no evident difference with healthy controls except for the decreased activation in contralateral precuneus to the direction of the head deviation.TWSTRS of patients with CD decreased from (20.02 ± 5.52) to (4.11 ± 4.34) with statistic significance (t =11.71,P =0.000) after botulinum toxin treatment.There was a positive correlation between cerebral activation pattern change in some cerebral areas (ipsilateral primary somatosensory cortex,premotor cortex,supplementary motor cortex,insula,fusiform,hippocampus with parahippocampa as well as contralateral middle temporal cortex and hippocampus with parahippocampa to the direction of the head deviation) and TWSTRS score decrease.Conclusions There are widespread abnormalities in cortical and subcortical activation pattern in patients with CD,which might due to dysfunction of sensory-motor integration.We speculate a basic pre-dystonic state is present in affected body parts prior to clinical symptoms appear.Botulinum toxin fulfills its subsequent central effect by reorganizing and normalizing the cerebral cortex in patients with CD.
