The outbreak of coronavirus disease 2019 (COVID-19) has resulted in significant morbidity and mortality worldwide. Vaccination against coronavirus disease 2019 is a use-ful weapon to combat the virus. Patients with chronic liver diseases (CLDs), including compensated or decompensated liver cirrhosis and noncirrhotic diseases, have a decreased immunologic response to coronavirus disease 2019 vaccines. At the same time, they have increased mortality if infected. Current data show a reduction in mortality when patients with chronic liver diseases are vaccinated. A suboptimal vac-cine response has been observed in liver transplant recipi-ents, especially those receiving immunosuppressive therapy, so an early booster dose is recommended to achieve a better protective effect. Currently, there are no clinical data com-paring the protective efficacy of different vaccines in patients with chronic liver diseases. Patient preference, availability of the vaccine in the country or area, and adverse effect profiles are factors to consider when choosing a vaccine. There have been reports of immune-mediated hepatitis after coronavi-rus disease 2019 vaccination, and clinicians should be aware of that potential side effect. Most patients who developed hepatitis after vaccination responded well to treatment with prednisolone, but an alternative type of vaccine should be considered for subsequent booster doses. Further prospec-tive studies are required to investigate the duration of immu-nity and protection against different viral variants in patients with chronic liver diseases or liver transplant recipients, as well as the effect of heterologous vaccination.

Brugada syndrome （BrS） is primary electrical disorder characterized by ST segment elevation with right bundle branch block morphology in patients with apparent structurally normal hearts, It predisposes affected individuals to ventricular tachycardia/fibrillation （VT/VF） and sudden cardiac death （SCD）.A number of studies have identified risk factors that are associated with a more malignant course of disease. These include male gender, syncope, a spontaneous type 1 ECG pattern, family history of SCD, family history of Brugada syndrome,

Suppression of Tumorigenicity 2 （ST2） is a member of the interleukin （IL）-1 receptor family The ST2 receptor exists in two isoforms - ST2 ligand （ST2L） and soluble ST2 （sST2）.ST2L is a membrane receptor and sST2 is a trun- cated receptor which is soluble in the blood, allowing it to be detected in serum. IL-33 is a member of the IL-1 family of ligand and is the fimctional ligand of ST2L receptor. It binds to the ST2L, thereby mediating its immune function.

Although single-atom catalysts(SACs)have attracted enormous attention for their applications in the electrochemical reduction of CO_(2)(CO_(2)RR)due to their extraordinary catalytic activity and well-defined active centers,neighboring effects and their influence on the electrochemical performance of SACs have not been well *** this review,we present a summary of the neighboring effects on SACs for the CO_(2)RR process,where the surrounding atoms not only induce electronic modulation of the metal atom but also participate in the CO_(2)*** theoretical and experimental studies have pointed out that the neighboring sites of the anchored metal center can provide second active/adsorption locations during the catalytic process,enhancing CO_(2)RR performance *** review supplies advanced insights into the significant roles and impacts of neighboring effects on the catalytic process,which also benefit the development of advanced SACs to achieve efficient electrocatalysis.

Prokaryotic type II adaptive immune systems have been developed into the versatile CRISPR technology, which has been widely applied in site- specific genome editing and has revolutionized biomedical research due to its superior efficiency and flexibility. Recent studies have greatly diversified CRISPR technologies by coupling it with various DNA repair mechanisms and targeting strategies. These new advances have significantly expanded the generation of genetically modified animal models, either by including species in which targeted genetic modification could not be achieved previously, or through introducing complex genetic modifications that take multiple steps and cost years to achieve using traditional methods. Herein, we review the recent developments and applications of CRISPR-based technology in generating various animal models, and discuss the everlasting impact of this new progress on biomedical research.

Complications aroused from Meckel’s diverticulum tend to developed in children. Children presented with abdominal pain, intestinal obstruction, intussusception or gastrointestinal bleeding may actually suffered from complicated Meckel’s diverticulum. With the advancement of minimally invasive surgery (MIS) in children, the use of laparoscopy in the diagnosis and subsequent laparoscopic excision of Meckel’s diverticulum has gained popularity. Recently, single incision laparoscopic surgery (SILS) has emerged as a new technique in minimally invasive surgery. This review offers the overview in the development of MIS in the management of children suffered from Meckel’s diverticulum. The current evidence in different laparoscopic techniques, including conventional laparoscopy, SILS, the use of special laparoscopic instruments, intracorporeal diverticulectomy and extracorporeal diverticulectomy in the management of Meckel’s diverticulum in children were revealed.
