ABSTRACT

OBJECTIVE@#To investigate the pre-treatment preventive maintenance and quality control procedure of MRI system and transcranial MRI-guided focused ultrasound (TcMRgFUS) treatment system by monitoring quality control of these two systems.@*METHODS@#The general performance index and image quality control index of MRI system, as well as the quality assurance program of TcMRgFUS EXABLATE 4000 system were tested and recorded.@*RESULTS@#The general performance index and image quality control index of MRI system met requirements.@*CONCLUSIONS@#Through system detection, the system performance could be monitored, ensuring the accuracy and safety of surgery.

ABSTRACT

Objective:To analyze the influence of factors before initiation of extracorporeal cardiopulmonary resuscitation (ECPR) on the prognosis of patients, so as to explore the intervention timing and improvement strategy of ECPR.Methods:A retrospective analysis was performed on 29 patients who underwent ECPR in the First Affiliated Hospital of Hunan Normal University (Hunan people's Hospital)from July 2018 to April 2021. Patients were divided into the survival group ( n = 13) and death group ( n = 16) according to whether they survived at discharge. The duration of conventional cardiopulmonary resuscitation (CCPR), initial heart rate before ECPR, the ratio of out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA), and the ratio of transported cases outside the hospital were compared between the two groups. According to different CCPR time, the patients were divided into the ≤45 min group, 45-60 min group and >60 min group to compare the hospital survival and sustained return of spontaneous circulation (ROSC) rate . According to the location of cardiac arrest, the patients from emergency department and other department were divided to compare the survival of IHCA. Results:The total survival rate was 44.83%, the average duration of extracorporeal membrane oxygenation (ECMO) was 114 (33.5, 142.5) h, and the average duration of CCPR time was 60 (44.5, 80) min. The duration of ECMO was longer in the survival group than in the death group ( P = 0.001). The duration of CCPR (the time from CPR to ECMO) in the survival group was significantly shorter than that in the death group ( P = 0.010). Patients with defibrillatory rhythm had higher hospital survival rate ( P = 0.010). OHCA patients had higher mortality than IHCA patients ( P = 0.020). Mortality of patients transferred from other hospitals was higher ( P = 0.025). Hospital survival and ROSC decreased in turn by CCPR duration ≤ 45 min, 45-60 min, and > 60 min ( P = 0.001). The location of CA occurrence had no impact on the hospital survival rate of IHCA patients ( P=0.54). Conclusions:Hospital survival of ECPR is higher than that of CCPR. ECPR is effective for refractory cardiac arrest. The prognosis of ECPR is significantly related to the duration of CCPR, initial heart rate, and location of CA. Education and team training should be strengthened to improve the survival rate of ECPR.

ABSTRACT

Based on a field survey of typical hospitals in Zhejiang,this paper drew a conclusion on three models of the mixed-ownership hospitals development in Zhejiang.It summed up the experiences learnt in the practice about how to maintain the public welfare of the public hospitals,how to ensure the essential health services supply as well as the incentive mechanism for social capital.Suggestions were proposed to develop the mixed-ownership hospitals based on the analysis.

ABSTRACT

Mixed-ownership hospitals constitute an experiment of such ownership in the health care sector,attracting high attention as of its birth.This paper introduced the background of such ownership,and analyzed the development of such hospitals in terms of policy,present situation and external effects.The authors,arguing against major challenges,stated their views on such hospitals along with in-depth analysis of key issues in their development.

ABSTRACT

Objective Plasma levels of matrix metalloproteinase-9 ( MMP-9 ) and serum level of high-sensitivity C reactive protein (hs-CRP) were detected to investigate their distributions between patients with stable stroke and those with asymptomatic intracranial artery stenosis and to explore their clinical significance. Methods The mean level of the serum hs-CRP of the group with recurrent stroke (2.34 mg/L)was the highest, followed by that of the group with the stable stroke( 1.45 mg/L),asymptomatic intracranial artery stenosis ( 1.31 mg/L) and control group (0.96 mg/L) ( P = 0.001 ). The level of the MMP-9 was in sequence of recurrent stroke group ( 121.82 ± 72.99 ) μg/L > asymptomaticintracranial artery stenosis group ( 119.18 ± 80.01 ) μg/L > stable stroke group( 112.76 ± 59.66) μg/L,while no statistical significance was found among groups( P = 0.947 ). However, the level of MMP-9 of three patient groups( 118.08 ± 71.06 ) μg/L was significant higher than control group( 57.55 ± 10.44 )μg/L (P <0.001 ). The spearman analysis for the relationship showed that the concentration of MMP-9 was positively associated with that of hs-CRP ( r = 0.337, P < 0.001 ). Conclusions The hs-CRP maintained a high level in stable stage of stroke. The MMP-9 level in the patients group was significant higher than control group and the level of MMP-9 was positively associated with that of hs-CRP which suggested MMP-9 might be correlated with atherosclerosis other than stroke occurrence.

ABSTRACT

Objective To study the effect of Qing Yi Tang(QYT) on bacterial and endotoxin translocation from intestine in acute hemorrhagic necrotizing pancreatitis(AHNP) in rats.Methods SD rats were randomly divided into 3 groups: AHNP group,AHNP +QYT treatment group and sham operation(SO) group.AHNP models were set up in the former two group,while the pancreas was only mobilized in SO group.After setting up the model,QYT was gavaged in the QYT group,while normal saline was gavaged in the SO group and AHNP group.The concentration of endotoxin(ET) and the DNA of E.coli expressoin in portal vein blood in three groups of rats were measured 24h later.Results The concentration of ET and amount of E.coli DNA in portal vein of QYT group were lower than those of AHNP group.Conclusions QYT can reduce significantly the concentration of ET and E.coli DNA in portal vein blood and decrease bacterial and endotoxin translocation from intestine in the AHNP rats.
