Objective · To compare the short and medium-term efficiency and safety of 1470 nm laser with foam sclerotherapy with ligation of great saphenous vein and 808 nm laser with foam sclerotherapy to treat varicose veins of lower extremity. Methods · Seventy-seven hospitalized patients patients and twenty-one day-surgery patients were retrospectively analyzed. Results · There was no obvious difference in the closure of great saphenous vein for short to medium-term efficiency between the day-surgery group and hospitalized group. The postoperative complications and recurrence rate of day-surgery group was not higher than that of the hospitalized group, but the degree of perioperative comfort, economic cost and the time returning to normal life of day-surgery group were superior to that of the hospitalized group. Conclusion · 1470 nm laser with foam sclerotherapy with ligation of great saphenous vein and 808 nm laser with foam sclerotherapy to treat varicose veins of lower extremity had similar clinical effect, but the degree of safety and comfort was higher and trauma was less. The day surgery with 1470 nm laser to treat varicose vein of lower extremity could also simplify the procedure of hospitalization and reduce the cost of health care, which could be a new option for patients.

The coronavirus disease 2019 (COVID-19) has caused global public health and economic crises. Thus, new therapeutic strategies and effective vaccines are urgently needed to cope with this severe pandemic. The development of a broadly neutralizing antibody against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is one of the attractive treatment strategies for COVID-19. Currently, the receptor-binding domain (RBD) of the spike (S) protein is the main target of neutralizing antibodies when SARS-CoV-2 enters human cells through an interaction between the S protein and the angiotensin-converting enzyme 2 expressed on various human cells. A single monoclonal antibody (mAb) treatment is prone to selective pressure due to increased possibility of targeted epitope mutation, leading to viral escape. In addition, the antibody-dependent enhancement effect is a potential risk of enhancing the viral infection. These risks can be reduced using multiple mAbs that target nonoverlapping epitopes. Thus, a cocktail therapy combining two or more antibodies that recognize different regions of the viral surface may be the most effective therapeutic strategy.
