Objective To investigate the correlation of the middle cerebral artery stenosis (MCAS) and the mild cognitive function impairment (MCI),and the clinical efficacy of statins in patients with MCI. Methods Six hundred and thirty-six patientse,who received transcranial color doppler ultrasound (TCD)assay, were enrolled in our hospital hospitalization or outpatients. The simple mental state examination (MMSE) and clinical dementia rating scale (CDR) were used as cognitive function assessment indexes. Forty-four cases of MCI with MCAS and 58 cases of MCI with NMCAS were used as the treatment group , who received the atorvastatin 20 mg every day , 56 cases of MCI with NMCAS were used as the control group , who only received the routine and basic diseases treatment. One yearlater,we determined the changes of MMSE and CDRagain. Results We detected 124 patients with MCAS, 512 patients with NMCAS, and 44 cases of MCAS patients with MCI, the prevalence was 35.5%,114 cases of NMCAS in patients with MCI, with the prevalence of 22.3%, the prevalence between the two groups was statistically different. One year later, the patients in the treatment group, MMSE score was improved, the score of MCI of the MCAS group improved more significantly. Conclusion The middle cerebral artery stenosis correlated with the occurrence of MCI. Atorvastatin could improve cognitive function in patients with MCI, especially for MCI which was caused by middle cerebral artery stenosis.

OBJECTIVE: To investigate the mechanism of the pulmonary injury in rats caused by chronic intermittent hypoxia (CIH) and to investigate the intervention effect of Edaravone. METHOD: Ninety-six male Wistar rats were divided into four groups randomly: the control group (NC), chronic intermittent hypoxia group (CIH), chronic intermittent hypoxia normal saline matched group (NS), chronic intermittent hypoxia edaravone treatment group (NE). The four groups were also divided into 1, 2, 3, 4 W time subgroups, and each time subgroup had 6 rats. After the experiment, sections of pulmonary were stained with hematoxylin-eosin (HE) and the level of SOD, MDA, PO2 and Ang II mRNA in rat homogenate pulmonary were measured. RESULT: Pulmonary histology revealed that the CIH group showed high levels of interstitial edema, alveolar atelectasis, inflammatory cell infiltration of alveolar epithelial cell, pulmonary injury were serious in 1, 2, 3, 4 W. But the pulmonary histology of the UC group and the NS group was normal. Compared with the NS group, pulmonary injury of NE group 1, 2, 3, 4 W, significantly decreased. Compared with the NC group, the levels of PO2 in the CIH group were decreased; while the compared with the NS group, the levels of PO2 in the NE group were increased. Compared with the UC group and NS group, the levels of Ang II mRNA in each time point in CIH group were increased gradually (P < 0.05), the content of MDA were increased in 1, 2, 3, 4 W (P < 0.05), they had reached the peak all at 4 W; while the SOD in each time point in CIH group were decreased gradually (P < 0.05) compared with that in UC group and NS group; The Ang II mRNA levels of CIH in pulmonary showed positive correlation with MDA [r = 0.782,P < 0.01]; while the Ang II mRNA levels of CIH in pulmonary showed negative correlation with SOD [r = - 0.904, P < 0.01]. CONCLUSION CIH can cause pulmonary injury through oxidative stress and activating Ang II, and Edaravone could prevent pulmonary injury induced by CIH through scavenging oxygen free radicals.

OBJECTIVETo evaluate the hemodynamic changes in the central branches of the middle cerebral artery in different stages of neonatal hypoxic-ischemic encephalopathy (HIE) and provide new evidence for clinical diagnosis of HIE.

METHODSFrom March, 2013 to July, 2013, a total of 136 newborn infants were diagnosed to have HIE in our center. We performed two-dimensional ultrasonography and color Doppler ultrasound for assessments of systolic velocity (Vs) and resistant index (RI) of the central branches of the middle cerebral artery. The data were compared with the results of a control group consisting of 251 normal full-term infants.

RESULTSInfants with mild HIE showed hyperechoic changes in the white matter around the ventricle, while in moderate and severe HIE, such hyperechoic changes were diffuse in both hemispheres with unclear echoes of the brain structures. Pulse Doppler assessments of hemodynamics of the central branches of the middle cerebral artery demonstrated a significant decrease in Vs and an increase in RI regardless of HIE severity (P<0.05). In addition, Vs and RI values in mild HIE infants differed significantly (P<0.05) from those in infants with moderate and severe HIE, who had comparable Vs and RI values (P>0.05).

CONCLUSIONTranscranial ultrasonography may provide dynamic information on cerebral blood flow in neonates and hemodynamic parameters of the central branches of the middle cerebral artery are valuable for clinical diagnosis and early intervention of HIE.

Objective:To study the hepatic hemodynamics changes and pathophysiological mechanisms of the use of a functional shunt after auxillary liver transplantation to treat portal hypertension associated with a small-for-size graft.Methods:A retrospective analysis of the clinical data of patients with portal hypertension treated with functional shunting of small-volume grafts from a living donor liver at the Beijing Friendship Hospital, Capital Medical University from July 2014 to December 2018, and a total of 6 patients were included as the research objects, including 4 males and 2 females, with a median age of 35.5 (29.0-52.0) years old. Blood flow monitoring data were collected during and after operation, and the characteristics of liver hemodynamics were analyzed.Results:The portal venous blood flow of the remnant native liver gradually decreased to no flow. As a buffer response, the flow velocity of hepatic artery increased. The portal venous blood flow of the graft gradually increased in the early postoperative period and then gradually decreased from post-operation Day 5 to 10 due to gradual increase in portal venous resistance. However, the portal venous perfusion gradually increased from Day 10 after the operation, reached to a level and declined to a stable level about 1 month after the operation. The volume of abdominal drainage slowly decreased after the peak level at Day 5-10 after the operation, and disappeared completely at Day 30 after operation.Conclusions:When using auxiliary liver transplantation for functional shunting to treat portal hypertension, autologous residual liver can act as a guide buffer for the pressure gradient of portal vein hyperperfusion in liver transplantation, and reach a steady state of blood flow distribution about 1 month after surgery, while relying on autologous remnant liver hepatic artery buffer response prevents small liver syndrome.

Objective:To review our experience in the use of "Full right-Full left" split liver transplantation in adult-to adult or adult-to adult-size child.Methods:The clinical data of liver donors to 4 recipients of full right-full left split liver transplantation performed at Beijing Friendship Hospital of Capital Medical University from January to December 2019 were reviewed. The surgical methods of split liver transplantation, cold ischemia time, operation time, intraoperative blood transfusion, and postoperative complications and prognosis were analyzed.Results:The 4 recipients of complete right hepatic-left hepatic split liver transplantation included 3 adults and 1 heavy child (45 kg). Their ages ranged from 14 to 48 years, and body weight ranged from 45 to 61 kg. The end-stage liver disease model score were 21, 12, 41, and 30 points. The ratios of graft mass to recipient's body mass ranged from 0.85% to 1.35%. The cold ischemia time was 457-650 min, and the operation time was 460-575 min. Early liver function recovered smoothly in all the 4 patients after transplantation, and no small liver syndrome occurred. Patients were followed up to 6 months after operation. One patient developed anastomotic biliary leak, which was cured by endoscopic retrograde cholangiopancreatographic treatment. Another patient developed biliary stricture presenting with repeated biliary tract infection despite percutaneous transhepatic puncture biliary drainage. A third patient died six months from lung infection.Conclusion:In properly selected patients, using full right-full left hemiliver by split liver transplantation increased organ utilization and provided patients with increased treatment opportunities.

Objective:To systematically synthesize the qualitative research on the attitude and experience of health care personnel towards the hospice care of patients with heart failure, so as to provide evidence support for hospice care.Methods:Qualitative research on the attitude and experience of health care personnel towards the hospice care of patients with heart failure was retrieved through computers in PubMed, Embase, Web of Science, CINAHL, China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database, VIP and Wanfang. The retrieval time limit was from the establishment of the database to July 1, 2022. The quality of the included article was evaluated using the quality evaluation criteria for qualitative research of the Joanna Briggs Institute Evidence-Based Health Care Center in Australia. The results were synthesized using the aggregation synthesis method.Results:Totally 15 articles were included. A total of 61 results were extracted, and 9 categories were included and 3 synthetic results were synthesized and summarized, namely, the timing of intervention, obstacle factors and promotion strategies of hospice care for patients with heart failure.Conclusions:Health care personnel should involve in hospice care in the early stage of heart failure and take into account the wishes, needs of patients and their families and prognosis of patients. Health care personnel should strengthen multidisciplinary cooperation and communication with patients and their families. Relevant departments need to provide guidance and support from the policy aspect, and strengthen the publicity and education of health care personnel, patients and their families. We will work together to integrate hospice care into the disease management of patients with heart failure, so as to improve the quality of life of patients.

Objective:To review the paper on the admittance evaluation indicators of palliative care for patients with heart failure, and clarify the admittance evaluation indicators of palliative care for patients with heart failure and corresponding evaluation criteria or tools at home and abroad.Methods:Based on the framework of the scoping review, paper retrieval was carried out through computer in PubMed, Web of Science, Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), WanFang Database, Chinese Biomedical Literature Database and VIP. The retrieval time limit was from the establishment of the database to April 30, 2022. The original research and review on the admittance evaluation of palliative care for patients with heart failure were included, and the data were independently screened and extracted by two researchers.Results:A total of 15 papers were included. The results of document integration showed that the admittance evaluation indicators of palliative care for patients with heart failure included four categories, namely, disease progress, patient needs, medical resource utilization and medical institutions. It included 12 evaluation indicators and corresponding evaluation criteria or evaluation tools, including the patient's expected survival period, cardiac function, high-risk biomarkers, exercise status, complications, advanced treatment, patient's subjective will, complex symptom relief needs, social support needs, multiple unplanned admissions, hospital stay extension, and medical institution software and hardware resources.Conclusions:The content of the admittance evaluation indicators of palliative care for patients with heart failure is comprehensive, but the evaluation criteria for some indicators are not clear, and there is no consensus on the whole. In the future, researchers can select sensitive evaluation indicators on the basis of existing research, construct the admittance evaluation indicators of palliative care for patients with heart failure, and verify it in clinical practice, so as to promote the application of palliative care in the disease management of patients with heart failure.
