  COVID-19 pandemic caused a major crisis, affecting and straining health care systems, including some very advanced ones. The pandemic may have also indirectly affected access to health care for patients with other conditions, not related to COVID-19, even in countries not overwhelmed by an outbreak.We analyzed and compared visits to the emergency room (ER) department during the same calendar period of 2019 and 2020 (from March 1 to March 31 of each year) in our hospital, a medium size, tertiary center, located in the center of Athens, which is not a referral center for COVID-19.Total ER visits were reduced by 42.3% and the number of those requiring hospitalization by 34.8%. This reduction was driven by lower numbers of visits for low risk, non-specific symptoms and causes. However, there was a significant decrease in admissions for cardiovascular symptoms and complications (chest pain of cardiac origin, acute coronary syndromes, and stroke) by 39.7% and for suspected or confirmed GI hemorrhage by 54.7%. Impt of non-COVID-19 diseases during the pandemic.
  Pain on injection is a well-recognized adverse event of propofol administration for the stimulation of general anesthesia. Pre-treatment with lidocaine or flurbiprofen axetil has proven to be effectual in the reduction propofol-induced pain in adults. Nonetheless, only few studies have evaluated the clinical therapeutic effects of lidocaine combination with flurbiprofen axetil to prevent pain on injection of propofol. The current study aims to evaluate the clinical therapeutic effects of lidocaine combination with flurbiprofen axetil to reduce pain on injection of propofol among adult patients.
 
  The literature search will be conducted from their inception to November 2020 from MEDLINE, EMBASE, Web of Science, and Cochrane Library databases without date or geographical restrictions. However, language will be restricted to publications in English and Chinese.  https://www.selleckchem.com/products/ABT-869.html  Two authors will independently screen abstracts and titles of all papers to determine whether to include or exclude them. The authors will also study characteristic and outcomes of data extraction and carry out risk of bias assessment. We plan to use either a fixed-effects or random-effects model to estimate the risk ratios (RR) or mean difference (MD) or standardized mean difference (SMD) together with 95% confidence interval (CI).
 
  This study will provide high-quality evidence for the clinical therapeutic effects of lidocaine combination with flurbiprofen axetil for reducing pain on injection of propofol in adult patients.
 
  This study will summarize current evidence for the management of pain on injection of propofol in adult patients and provide guidance for both intervention and future research.
 
  Since no data collection will be involved, there is no need for an ethics approval.

  Previous studies have showed that the high expression of urokinase plasminogen activator (uPA) in pathology and serology is closely related to the progression of hepatocellular carcinoma (HCC). However, there are no systematic reviews for these evidence, and the association between uPA and HCC is still not completely understood. Therefore, we will undertake a systematic review of the literature to summarize previous evidence regarding this topic, in order to clarify the prognostic significance of uPA in HCC.
 
  Studies comparing the HCC patients with high and low expression of uPA on the clinicopathological features and the prognosis are eligible for this review. Outcomes include all endpoints about survival and clinicopathological features. Prospective or retrospective primary studies which published in English will be included. Four databases of Medline, EMBASE, Web of Science, and the Cochrane Library will be systematically searched from their inception to Mar 2021 to retrieve relevant studies.

  Guillain-Barré syndrome (GBS) is an acute autoimmune neurological disorder mainly involving the peripheral nerves. Currently, various cytokines have been shown to be involved in the pathogenesis of GBS. Because of their similar biological structures, interleukin (IL)-36α, IL-36β, IL-36γ, and IL-36 receptor antagonist (Ra) were all renamed and collectively called IL-36 cytokines. The roles of IL-36 cytokines in GBS currently remain unclear.Forty-two patients with GBS and 32 healthy volunteers were included in our study. Serum IL-36α, β, γ, and interleukin-36 receptor antagonist (IL-36Ra) levels of patients with GBS in the acute and remission phases and healthy volunteers were measured by enzyme-linked immunosorbent assay (ELISA). In addition, we examined the serum levels of other inflammatory factors that have been shown to be involved in GBS pathogenesis, represented by IL-17 and tumor necrosis factor-α (TNF-α). Furthermore, the correlations between the serum levels of IL-36 cytokines and different clinicalIL-17 and TNF-α levels, while serum IL-36Ra levels were negatively correlated with the levels of these 2 inflammatory factors. Similar results were observed in cerebrospinal fluid (CSF), IL-36α and IL-36γ levels in CSF were positively correlated with GDSs, while IL-36Ra levels in CSF were negatively correlated with GDSs. Additionally, the serum and CSF levels of IL-36α and IL-36γ in the axonal subtype of GBS patients were higher than those in the demyelination subtype.Based on our findings, IL-36 cytokines may be involved in the pathogenesis of GBS and some of these cytokines may help predict the disease severity and other clinical characteristics of GBS.
