  • Protein-energy wasting of maintenance hemodialysis patients

    Protein-energy wasting is one of the common complications of maintenance hemodialysis patients. It often causes decreased immune function, increased anemia, and decreased heart, brain, lung and other organ functions, resulting in decreased quality of life, decreased long-term survival rate, and increased mortality. This article discusses the causes, diagnosis, evaluation methods, intervention and prevention of protein-energy wasting in maintenance hemodialysis patients, and aims to provide a theoretical basis for evaluating the nutritional status, early intervention for protein-energy wasting, and improving prognosis and quality of life of maintenance hemodialysis patients.

  • Distal aortic remodeling after open repair of Stanford type A acute aortic dissection

    The replacement of thoracic aorta and elimination of proximal intimal tear are the classic methods for the treatment of Stanford type A aortic dissection. However, some patients still have residual tears in the distal aorta after operation and lead to dilation of the false lumen due to continuous perfusion. As negative remodeling of distal aorta is closely related to the long-term prognosis of patients, the exploration of related influencing factors has attracted the attention of scholars recently. We aim to review the definition, pathological mechanism and risk factors of unfavorable remodeling after open surgery.

  • Adrenal insufficiency after cardiovascular surgery with cardiopulmonary bypass

    Relative/absolute adrenal insufficiency is not uncommmon in the patients undergoing cardiovascular surgery with cardiopulmonary bypass. However, this complication was rarely reported due to its unspecific clinical presentations and the unawareness of ICU physicians and cardiac surgeons. However, this puts them on a higher risk of hemodynamic instability and cardiovascular adverse events during hospitalization. Systematic reviews concentrated on it are rarely reported currently. We aim to review the etiology, risk factors, potential pathogenesis and related research progress for this complication.

  • Functional role and underlying mechanisms of neuropilin-1 in proliferation and migration of rat vascular smooth muscle cells

    ObjectiveTo investigate the role and potential mechanisms of neuropilin-1 (NRP1) in the pathogenesis of vein graft failure.MethodsThe rat vascular smooth muscle cells (VSMCs) were transfected with NRP1-shRNA adenovirus and negative control adenovirus respectively. Cell counting kit-8, flow cytometry, Transwell and Western blot were used to investigate the effects of inhibition of NRP1 on VSMCs proliferation viability, apoptosis, migration capacity and its downstream signaling pathway protein expression.ResultsThe proliferation and migration of rat VSMCs could be inhibited after down-regulation of NRP1, and the increase of apoptosis was also observed. Moreover, inhibition of NRP1 significantly reduced Akt and NF-κB phosphorylation in rat VSMCs, but had little effect on activation of ERK1/2.ConclusionNRP1 may promote vein graft hyperplastic remodeling by regulating the proliferation and migration of VSMCs through PI3K/Akt and NF-κB pathways, but further animal study is required.

  • Research progress on silent cerebral infarction after cardiac surgery through cardiopulmonary bypass

    In the absence of symptoms, silent cerebral infarction can be discovered incidentally during an imaging or neuropathological examination. After cardiovascular surgery with cardiopulmonary bypass, the morbidity is high, and it may contribute to neurocognitive dysfunction, symptomatic cerebral infarction and increased risk of death. The embolus caused by various operations intraoperatively are closely associated with this progress. However, controversies over the prevention still persist. As a result, an overall summary of silent cerebral infarction after cardiovascular surgery with cardiopulmonary bypass will be presented in this review.

  • Analysis of protein differences in aortic aneurysm/dissection based on tandem mass tag proteomics

    ObjectiveTo analyze the differences in proteins between aneurysm/dissection patients and healthy subjects, and subsequently figure out differential proteins related to medial degeneration of aortic aneurysm/dissection.MethodsAortic wall samples were collected from 6 male aortic aneurysm patients (an aortic aneurysm group, mean age 56.50±8.19 years), 6 male aortic dissection patients (an aortic dissection group, mean age 54.17±6.68 years) and 6 male healthy subjects (a normal group, mean age 40.50±9.31 years) between December 2019 and May 2020 in West China Hospital of Sichuan University. Quantitative proteomics was performed using tandem mass tag (TMT) techniques, followed by gene ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis.ResultsA total of 63 differential proteins were obtained both in the aortic aneurysm group and the aortic dissection group compared with the normal group, with 30 up-regulating and 33 down-regulating. The differential proteins were involved in multiple biological processes and clusted on peroxisome proliferators-activated receptor (PPAR) signaling pathway, extracellular matrix-receptor interaction signaling pathway and complement and coagulation cascades signaling pathway.ConclusionThe identified proteins may help to demonstrate new molecular mechanisms related to medial degeneration of aortic aneurysm/dissection.

  • Risk factors for children with tic disorder: a systematic review

    Objective To systematically review the risk factors of tic disorder (TD) in children. Methods Databases including PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, CBM, VIP, and WanFang Data were electronically searched to collect observational studies on children with TD from inception to June 29th 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.3 software. Results A total of 32 studies involving 556 560 children were included. The results of meta-analysis showed that the risk factors for TD were as follows: male (OR=2.23, 95%CI 1.08 to 4.61, P=0.03), premature delivery (OR=1.66, 95%CI 1.04 to 2.64, P=0.03), low birth weight (OR=1.27, 95%CI 1.07 to 1.50, P=0.005), history of neonatal jaundice (OR=7.46, 95%CI 1.15 to 48.42, P=0.04), other adverse factors in the perinatal period (OR=2.74, 95%CI 1.89 to 3.98, P<0.000 01), poor eating habits (OR=2.11, 95%CI 1.52 to 2.93, P<0.000 01), long-term viewing of electronic products (OR=2.22, 95%CI 1.31 to 3.75, P=0.003), history of febrile convulsions (OR=2.43, 95%CI 1.21 to 4.86, P=0.01), recurrent respiratory infection (OR=2.63, 95%CI 1.49 to 4.64, P=0.000 8), chronic tonsillitis (OR=2.01, 95%CI 1.31 to 3.09, P=0.001), rhinopathy (OR=1.77, 95%CI 1.35 to 2.31, P<0.000 1), attention deficit hyperactivity disorder (ADHD) (OR=5.32, 95%CI 3.77 to 7.51, P<0.000 01), decreased blood iron content (OR=3.68, 95%CI 1.56 to 8.67, P=0.003), family history of TD (OR=6.33, 95%CI 3.20 to 12.53, P<0.000 01), family history of mental illness (OR=2.39, 95%CI 2.03 to 2.83, P<0.000 01), maternal mental disorder during pregnancy (OR=2.49, 95%CI 1.99 to 3.11, P<0.000 01), alcohol drinking during pregnancy (OR=1.40, 95%CI 1.09 to1.79, P=0.007), smoking or passive smoking during pregnancy (OR=1.84, 95%CI 1.68 to 2.01, P<0.000 01), and corporal punishment (OR=3.57, 95%CI 1.52 to 8.34, P=0.003). Parity (second birth and above) (OR=0.41, 95%CI 0.25 to 0.68, P=0.000 6) was a protective factor for tic disorder. Conclusions Current evidence shows that the incidence of TD is related to gender, family history of mental illness, maternal life habits during pregnancy, perinatal history, chronic respiratory diseases, abnormal trace elements, and strict education methods, etc. Moreover, parity is a protective factor for the occurrence of TD. Due to the limited quantity and quality of included studies, more high-quality studies are required to verify the above conclusions.

  • Hybrid or open surgery for aortic arch diseases: Which one is better?

    The conventional total arch replacement (cTAR) with frozen elephant trunk implantation is commonly regarded as the gold standard for aortic pathologies involving ascending aorta and proximal aortic arch. By combining open supra-aortic vessels debranching and emerging endovascular technologies, hybrid arch repair (HAR) has been increasingly performed as a promising alternative in risky patients with comorbidities and frailties. Nevertheless, the advantages or disadvantages of hybrid arch procedures and cTAR in terms of survival and related outcomes remain controversial. This study is aimed to briefly review the role and results of HAR in the management of aortic arch pathology in comparison of contemporary cTAR.
