Drug-eluting stents have great impact to the coronary artery bypass grafting(CABG) in cardiac surgery. Someone even believes that it could replace the surgery procedure. However, the drug-eluting stents are not so ideally in the clinic practice. There are no significant difference between drug-eluting stents and bare metal stents in the mortality and the angina recurrence in middle-long term follow-up. The same results are in the compare with the CABG. As the challenge of the drug-eluting stents, the cardiac surgery has many aspects practice and progress in the harvest of the bypass graft. In the article, the change of the CABG conduit in the era of drug-eluting stents are reviewed.
Krüppel-like factor 4 (KLF4) is a member of the sample Kruppel transcription factor protein family, is an evolutionary conservative contain zinc finger transcription factors, involved in regulating many cellular processes, such as cell growth, proliferation, differentiation and invasion, KLF4 expression in a variety of tissues and cells in the body, has widely in many physiological and pathological conditions. Many studies have shown that KLF4 is involved in neurobiological processes such as neuroinflammation, oxidative stress, apoptosis and axon regeneration, and is closely related to a variety of nervous system diseases such as epilepsy, stroke, and Alzheimer’s disease. Now KLF4 in its role in the development of nervous system diseases were reviewed, help to understand the pathogenesis of the disease and clinical treatment for diseases of the nervous system to provide potential targets.
ObjectiveTo analyze the clinical characteristics, risk factors, treatment and prognosis of epilepsy secondary to cerebral infarction.MethodsThe clinical data of 109 patients with epilepsy secondary to cerebral infarction admitted to the Affiliated Central Hospital of Shandong First Medical University from October 2018 to February 2021 were retrospectively analyzed, including the location of cerebral infarction, seizure type, seizure time and antiepileptic treatment.Results3 426 patients with cerebral infarction were treated in the same period, and the incidence of epilepsy secondary to cerebral infarction was 3.18%. Among 109 patients with epilepsy secondary to cerebral infarction, 71 were male and 38 were female, the average age was (67.42 ± 28.58) years. Time of seizure after cerebral infarction: 67 cases (61.47%) were early onset epilepsy and 42 cases (42.47%) were late onset epilepsy. The infarct site: 63.30% (69 /109) in cortex, 11.93% (13/109) in subcortical area, and 24.77% (27/109) in lacunar infarction secondary epilepsy. 5 cases died, the fatality rate was 1.59%, of which 4 patients died of early onset epilepsy, status epilepticus, and 1 patient died of late onset epilepsy due to acute cerebral infarction.ConclusionsIn patients with epilepsy secondary to cerebral infarction, the cortex is the most common site of infarction; focal seizures are more than comprehensive seizures; status epilepticus often indicates poor prognosis, so timely antiepileptic treatment should be given to improve the prognosis.
ObjectivesTo systematically review the application of evidence-based medicine (EBM) combined with problem-based learning (PBL) method in clinical teaching.MethodsDatabases including WanFang Data, CNKI, VIP, CBM, PubMed and EMbase were searched to identify eligible randomized controlled trials that compared EBM plus PBL with traditional lecture based learning (LBL) method in clinical teaching from inception to March 28th, 2020. Two reviewers independently screened literature, extracted data and assessed risk bias of included studies. Statistical analysis was performed using Stata 14.0 software.ResultsA total of 33 randomized controlled trials with 2 855 students were included. The results showed that students in EBM combined with PBL group obtained better scores of specialized theory (WMD=6.87, 95%CI 5.08 to 8.66, P<0.001), skills examination (WMD=10.57, 95%CI 8.98 to 12.16, P<0.001) and case analysis (WMD=9.79, 95%CI 4.71 to 14.88, P<0.001), comparing with those in LBL group. Besides, EBM combined with PBL method improved students’ overall ability including independent learning capability, clinical thinking ability, problem-solving capability, literature exploring capacity, communication and presentation skills and team-work ability.ConclusionsApplication of EBM combined with PBL method can improve clinical teaching quality.
Esophageal cancer is a highly prevalent tumor species in Henan province, which brings heavy medical burden to families and society. Surgical treatment plays a dominant role in the treatment of non-advanced esophageal cancer. However, cancer cells in esophageal cancer lesions are highly invasive, postoperative recurrence and metastasis rates are pretty high. More effective systemic and comprehensive treatment is urgently needed to improve the prognosis. We invited 52 doctors in esophageal surgery, oncology, pathology, imaging, and radiation therapy of 32 hospitals at all levels in Henan province, to repeatedly negotiate and fully discuss in combination with evidence and clinical practice experience. Finally, “diagnosis and treatment pathway of neoadjuvant immunotherapy for esophageal cancer in Henan province” was formulated. In this treatment pathway, seven recommendations were proposed from seven perspectives including target population, patient evaluation, protocol selection, surgical timing, postoperative management, organ preservation, and general principles to offer reference for medical personnel related to esophageal cancer surgery.
