Objective To investigate the risk of death between older and non-older critical patients in intensive care unit (ICU) in Shuyang People's Hospital.Methods A retrospective cohort study was conducted. The critical patients who aged 15 or above, and admitted to ICU of Shuyang People's Hospital from January 2014 to December 2016 were enrolled, and all the data was collected from theregistration and electronic medical records in the ICU. The prevalence and causes of death in ICU critical patients during the study period were observed. The patients were divided into elderly group (65 years and older) and non-elderly group (15-65 years), and logistic regression analysis was performed for the risk of death in the two groups.Results During the study period, 2707 critical patients in emergency were admitted to the ICU of Shuyang People's Hospital, and patients not satisfied the inclusion criteria were excluded. Finally, a total of 2466 patients were enrolled in the analysis with the male and female ratio of 1.6 : 1, an average age of (61.8±17.3) years, a median Glasgow coma scale (GCS) score of 6 (4, 8), and with a median ICU stay of 3 (1, 6) days. In 2466 critical patients, the most common cause of critical state was spontaneous intracerebral hemorrhage (25.5%) and traumatic brain injury (17.0%), with a fatality rate of 46.0% and 39.5% within first 7 days respectively. Compared with the non-elderly patients (n = 1415), the incidences of death of the elderly patients (n = 1051) due to traumatic brain injury, cerebral infarction, heart failure/cardiovascularcrisis, and respiratory critically ill were significantly increased (9.4% vs. 4.7%, 2.9% vs. 0.8%, 5.0% vs. 2.1%, 2.5% vs. 1.0%, respectively), while the incidence of death for pesticide/drug poisoning in the elderly group was significantly lower than that in the non-elderly group (0.2% vs. 1.2%, allP < 0.01). Stepwise logistic regression analysis showed that traumatic brain injury [hazard ratio (HR) = 1.878, 95% confidence interval (95%CI) = 1.233-2.864,P = 0.003), cerebral infarction (HR = 0.435, 95%CI = 0.229-0.826, P = 0.011), heart failure/cardiovascular crisis (HR = 0.399, 95%CI = 0.238-0.668,P = 0.000), and respiratory critically ill (HR = 0.239, 95%CI = 0.126-0.453,P= 0.000) in the older patients were significantly high risk factors of death as compared with those in non-older patients.Conclusions In the general ICU, the most common cause is spontaneous intracerebral hemorrhage and traumatic brain injury in critical patients with a high fatality rate. The risk of death in elderly patients with severe traumatic brain injury, cerebral infarction, heart failure/cardiovascular crisis, respiratory critically ill is higher than that of the non-elderly patients.

Background and Objectives: Stroke mimics are medical conditions producing stroke-like symptoms but eventually get diagnosed as non-stroke diseases. Epileptic seizure is a common type of stroke mimic. The purpose of this study is to investigate the application of emergency multimodal computed tomography (CT) in the diagnosis of epileptic seizure. Methods: We retrospectively reviewed the case group of patients with suspected stroke in the emergency stroke care service of the First Affiliated Hospital of Suzhou University from September 2017 to October 2019. We included those who underwent multimodal CT, including non-contrasted cranial CT, CT perfusion with CT angiography, and were ultimately diagnosed as epileptic seizures. Ten patients with acute anterior circulation ischemic stroke were assigned as controls. Results: A total of five cases met the inclusion criteria. Multimodal CT was completed within 2.25 to 3.50h from symptom onset. On CT perfusion, hyperperfusion was shown in four cases and slightly increased perfusion in one case with epileptic seizures. Cerebral blood flow and cerebral blood volume were significantly increased, while time to peak and mean transit time decreased in the regions of interest of the epileptic hemisphere when compared to either the non-affected hemisphere or the ischemic area in the control group (P<0.05). The abnormal perfusion areas did not follow vascular territory supply and CT angiography did not show vessel occlusion in the case group. Conclusion: Emergency multimodal CT could be used effectively to differentiate epileptic seizure from stroke.

Objective To evaluate reference range for fasting venous blood cells in the healthy 51 584 elderly people from Shuyang,China.Methods Totally 1000 non-old people and 51 584 elderly people were involved in this study.Fasting venous blood cells were collected from each group of subjects using standard procedures.The collected aliquots were processed according to standard operating procedures to determine participants' complete blood counts.Non-parametric methods were employed to calculate the reference intervals and 95 ％ confidence intervals for complete blood counts by Sysmex XE-2100 blood cell analyzer.Results The reference ranges of fasting venous blood cells in elderly subjects (male,female) were [(3.25-9.45) × 109/L and (3.35-9.39) × 109/L,WBC];[(3.87-5.55) × 1012/L and (3.71-5.19) × 1012/L,RBC] ; [(116.2-169.5)g/L and(107.4-153.6)g/L,Hb] ; [(37.2-52.4) ％ and(35.2-48.6) ％,HCT] ; [(86.3-104.8)fl and (85.2-103.5) fl,MCV] ; [(27.0-33.4) pgand(26.4-32.5)pg,MCH]; [(297.1-335.4)g/L and(293.3-330.5)g/L,MCHC];[[(38.4-54.2) and (38.6-52.9),RDW-SD]; [(11.3-15.4)％ and(11.4-15.3)％,RDW-CV];[(98.8-303.8) × 109/L and (109.9-334.8) × 109/L,PLT] ; [(1.10-3.42) and (1.20-3.78) ml/L,PCT];[(11.2-15.6) fl and(11.3-15.5)fl,MPV]; [[(8.89-16.7)％ and(9.48 17.1)％,PDW];[(20.3-49.1) ％ and (20.5-48.6) ％,PLCR],respectively.13 parameters of fasting venous blood samples in elderly people had statistically significant differences compared with non-old people (all P ＜0.05).Conclusions The reference range of fasting venous blood samples in elderly people are significantly different from non-old people.It is necessary to scientifically and reasonably establish the reference ranges for fasting venous blood cells in local elderly people.

Objective:To elucidate the phenomenon that epileptic seizure occurs in patients with epilepsy without definite diagnosis when driving a motor vehicle and its hazards.Methods:From January 2020 to June 2022, 7 epileptic patients who experienced traffic accidents caused by seizures were selected from the First Affiliated Hospital of Soochow University, and their demographic data, traffic accident related data and epilepsy diagnosis and treatment data were summarized and analyzed.Results:A total of 7 adult patients with epilepsy were collected, including 6 males, 4 of whom had been driving for more than 10 years. Among them, 1 patient drove a bus, and the other 6 patients drove private cars. Totally 5/7 of the accidents resulted in personal injury, and 3/7 of the accidents resulted in personal death. In 5 patients, video electroencephalogram showed interictal epileptiform discharges. In 2 patients, the imaging findings suggested the presence of cerebral cortical lesions that may lead to seizures. In terms of the form of seizure, 3 patients′ seizure type was focal to bilateral tonic-clonic, and the other 4 patients were very probable to be focal impaired awareness seizure.Conclusions:Undiagnosed epileptic seizures lead to traffic accidents, endanger patients and public safety, which need to attract attention from both doctors and patients, as well as the whole society.

Objective To study the effect of carboxyamidotriazole-orotate(CTO)on the proliferation and fatty acid anabolism regulation of human pancreatic cancer cells.Methods Human pancreatic cancer cell lines AsPC-1,AsPC-1/GEM(AR),PANC-1 and MiaPaCa-2 were used as the study subjects;cell survival rate was detected by sulfo-nylrhodamine B(SRB);the mRNA level of key genes for fatty acid synthesis was detected by qPCR;the protein level of the AMPK/ACC pathway was detected by Western blot;intracellular lipid metabolites were examined by liquid chromatography-mass spectrometry(LC-MS).Results Comparing to control group,CTO significantly de-creased the cell viability of AsPC-1,AR,PANC-1,and MiaPaCa-2(P＜0.05).CTO down-regulated the mRNA level of key fatty acid synthesis genes(P＜0.05).CTO significantly reduced the protein expression of AMPK,ACC and c-Myc(P＜0.05),while increasing the protein expression of p-AMPK and p-ACC(P＜0.05).CTO decreased lipid metabolite content in AR cells(P＜0.05).Conclusions CTO attenuates cellular fatty acid anabolism by inhibition of oncogene c-Myc expression and AMPK/ACC pathway,down-regulates the expression of fatty acid synthesis-related genes,and then inhibits proliferation of the human pancreatic cancer cell lines AsPC-1,AR,PANC-1 and MiaPaCa-2.
