ABSTRACT
Intravenous thrombolysis is an effective treatment for acute ischemic stroke, but its benefits are time-dependent. The time from onset to intravenous thrombolysis is divided into onset-to-door time (ODT) and door-to-needle time (DNT). The former reflects pre-hospital delay, while the latter reflects in-hospital delay and can be controlled by stroke improvement plan. This article reviews the influence of DNT on clinical outcomes, the influencing factors of DNT and the stroke improvement plan to shorten DNT.
ABSTRACT
Objective:To compare the clinical value of stent assisted intestinal bypass and temporary loop ileostomy in laparoscopic low anterior resection of rectal cancer.Method:In this retrospective analysis, 57 patients undergoing laparoscopic low anterior resection for rectal cancer in the First Affiliated Hospital of Ningbo University from Jan 2020 to Jan 2022 were divided into intestinal bypass group (36 cases) and loop ileostomy group (21 cases).Result:There were no significant differences in postoperative GI function recovery and postoperative complication rate between the two groups (all P>0.05). The levels of albumin, prealbumin and hemoglobin in the intestinal bypass group were better than those in the ileostomy group when evaluated on 3rd months after operation [(40.5±2.3) g/L vs. (38.1±2.6)g/L、(26.4±2.7)mg/dl vs. (24.5±2.0)mg/dl、(137.6±5.9) g/L vs. (134.0±7.0) g/L, t=3.605、2.743、2.085, all P<0.05]. Hospital expenses of the intestinal bypass group was lower [(571 000±7 500) yuan vs. (69 300±9 100) yuan, t=-5.477, P<0.05]. Conclusion:Compared with traditional ileostomy, the stent assisted intestinal bypass reduces trauma with lower expenses and improves patients' status after laparoscopic low anterior resection for rectal cancer.
ABSTRACT
Carotid atherosclerotic plaque rupture and thrombosis are the independent risk factors of acute ischemic cerebrovascular disease. Early identification of vulnerable plaques provides the evidence for early intervention in patients with asymptomatic carotid artery stenosis, and also helps to reduce the recurrence risk in patients with symptomatic carotid artery stenosis. This article focuses on comparing the advantages and limitations of the available clinical imaging methods in identifying vulnerable carotid artery plaque, and provides relevant prognostic indicators for patient risk stratification in clinical work.
ABSTRACT
Objective To explore the current residents training of standardized training program and their attitude towards the program,so as to provide suggestions for optimizing the training system.Methods Questionnaire surveys were carried out among 1 427 resident physicians from 10 hospitals in 7 provinces and cities between March 2017 to May 2017.The investigation covered demographic information,current work and study,training effect and problems.Statistical description and x2 test were used for analysis.Results Only 18.08％ of the residents in standardized training program considered it as unnecessary,while 80％ of them agreed with its effectiveness in improving their clinical skills and humanistic quality.67.29％ of them thought of resignation because of low income and high work pressure.Compared with " double track" residents,those of "double-track integration" complained of lower income and higher workload.Conclusions Chinese residents in standardized training program had a positive attitude towards the training system.However,the measures should be improved to prevent from possible occupational burnout.It is suggested that professionalism and professional identity education be improved,and subjective well-being feeling of residents be focused to avoid burnouts.

ABSTRACT
Objective To investigate the clinical value of miRNA-34a,miRNA-34c,and miRNA-135a in the early diagnosis of mild cognitive impairment (MCI) and Alzheimer's disease (AD).Methods The patients were collected in the outpatient and inpatient of Neurology during Aug 2014 to May 2016.The levels of miRNA-34a,miRNA-34c,an dmiRNA-135a were detected with quantitative real-time polymerase chain reaction (qRT-PCR).Results AD patients had higher level of miRNA-34a than the controls.The levels of miRNA-34c were higher in MCI and AD patients,while lower levels of miRNA-135a compared to the controls.Conclusions The miRNA 34a and miRNA-135a were likely to became the biomarker in early diagnosis of MCI and AD.
ABSTRACT
A series of studies have demonstrated that bone marrow mesenchymal stem cells (MSCs) are attractive candidates for cell and gene therapies, because they are readily obtained and multipotentially differentiated. Then homogeneous MSC cultures in vitro with more rapidly self-renewing ability and multipotential differentiation will accelerate and improve their progress in clinical application. Colter et al. found that early colonies contain a third kind of cells very small round cells that rapidly self-renew, besides spindle-shaped cells and large flat cells, called RS cells. RS cells are characterized by their extremely small size, rapid rate of replication, and enhanced potential for multilineage differentiation. Moreover, they can be distinguished from more mature cells in the same cultures by a series of surface epitopes and expressed proteins. Therefore, the results raise the possibility that RS cells may have the greatest potential for long-term engraftment and differentiation in vivo.
