In March 2020, the WHO declared the COVID-19 disease as a pandemic disease. There have been studies on the COVID-19 to find a certain treatment, but yet, there is no certain cure. In this article, we present a possible way to treat severe cases of COVID-19. ⋯ It is expected that these similarities (structural and affinity to the receptor of ACE2) can lead to the same pathophysiological activity of the virus by the use of ACE2 and FcγRII (the antibody-dependent enhancement mechanism). Therefore, we propose a way of washing out (by plasmapheresis) the possible antibodies against the spike protein of the virus out of patients' plasma to stop the antibody-dependent enhancement (ADE)-mediated infection of the immune system cells at the first phase of the treatment and simultaneous use of the anti-ACE2 with anti-FcγRII monoclonal antibodies at the second phase. We propose these procedures for the patients that have no significant response for typical anti-viral, ARDS and conservative therapies, and the disease persists or progresses despite sufficient therapies.

This study was conducted to explore whether the effect of edaravone (5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol3-one, EDR) can ameliorate renal warm ischemia-reperfusion injury (IRI) by modulating endoplasmic reticulum stress (ERS) and its downstream effector after cardiac arrest (CA) and cardiopulmonary resuscitation (CPR) in a rat model. ⋯ In conclusion, we found that EDR ameliorates renal warm IRI by downregulating ERS and its downstream effectors in a rat AKI model evoked by CA/CPR. These data may provide evidence for future therapeutic benefits of EDR against AKI induced by CA/CPR.

Randomized Controlled Trial Comparative Study
Comparison of dexmedetomidine and sufentanil as adjuvants to local anesthetic for epidural labor analgesia: a randomized controlled trial.
The epidural dexmedetomidine combined with ropivacaine has been successfully used for labor analgesia. We compared the effects of dexmedetomidine and sufentanil as adjuvants to local anesthetic for epidural labor analgesia. ⋯ Dexmedetomidine is superior to sufentanil in analgesic effect and duration in first-stage labor during epidural analgesia when combined with 0.1% ropivacaine (www.chictr.org.cn, registration ChiCTR-OPC-16008548).

Randomized Controlled Trial
The effect of midazolam administration for the prevention of emergence agitation in pediatric patients with extreme fear and non-cooperation undergoing dental treatment under sevoflurane anesthesia, a double-blind, randomized study.
Background: Sevoflurane is generally the preferred anesthetic agent for general anesthesia in pediatric patients, due to its rapid induction and recovery characteristics. However, it has been recognized that a major complication is emergence agitation when awakening from general anesthesia. The aim of this study was to evaluate the occurrence rate of emergence agitation in the operating room and postoperative recovery area following intraoperative administration of midazolam to pediatric patients under general anesthesia. ⋯ The odds ratio between PAED score and Disability was 2.5. Conclusion: Administration of a single dose of 0.1 mg/kg midazolam dose significantly decreases the incidence of severe emergence agitation at the emergence after sevoflurane anesthesia, but not at the recovery phase. Furthermore, the evaluation of sedative and agitation condition using RASS score at emergence from anesthesia is useful to predict occurrence of agitation in the recovery phase.

Multicenter Study
Efficacy and Safety of Umbilical Cord Mesenchymal Stem Cell Therapy for Rheumatoid Arthritis Patients: A Prospective Phase I/II Study.
The traditional anti-inflammation disease-modifying anti-rheumatic drugs (DMARDs) have limited therapeutic effects in rheumatoid arthritis (RA) patients. We previously reported the safety and efficacy of umbilical cord mesenchymal stem cell (UC-MSC) treatment in RA patients that were observed for up to 8 months after UC-MSC infusion. The aim of this study is to assess the long-term efficacy and safety of UC-MSC along with DMARDs for the treatment of RA. ⋯ UC-MSC cells plus DMARDs therapy can be a safe, effective and feasible therapeutic option for RA patients.
