Prevalence of respiratory viruses among hospitalized children with lower respiratory tract infections during the COVID-19 pandemic in Wuhan, China.

OBJECTIVES: We aimed to investigate the continuous changes in respiratory virus epidemics in hospitalized children with lower respiratory tract infections (LRTIs) persisting from January 2019 to December 2022 in Wuhan, China. METHODS: We retrospectively enrolled children with LRTIs admitted to the Wuhan Children's Hospital. Specimens were nasopharyngeal aspirates which had been collected and detected the following microorganisms with direct immunofluorescence: influenza virus types A and B, respiratory syncytial virus, parainfluenza virus types 1-3, and adenovirus. We also analyzed demographic data and laboratory test results. RESULTS: A total of 22,660 patients were enrolled. The total virus detection rate in 2019, 2021, and 2022 significantly declined gradually (36.96% vs 29.47% vs 22.62%, P value < 0.001). All the detected viruses did not follow previously observed seasonal patterns during the COVID-19 pandemic. Children hospitalized for LRTIs were older during the COVID-19 pandemic in contrast to the pre-period, particularly notable in cases attributed to respiratory syncytial virus and parainfluenza virus type 3 infections. CONCLUSIONS: This work adds to our knowledge of the epidemiology characteristics of respiratory viruses spanning the COVID-19 pandemic among children with LRTIs. The circulation of respiratory viruses changed consistently, and active LRTI surveillance in children remains critical for defining the healthcare burden of respiratory viruses.

Potential Mechanisms of Action of Chinese Patent Medicines for COVID-19: A Review.

Coronavirus disease 2019 (COVID-19) is an emergent infectious pneumonia caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is highly contagious and pathogenic. COVID-19 has rapidly swept across the world since it was first discovered in December 2019 and has drawn significant attention worldwide. During the early stages of the outbreak in China, traditional Chinese medicines (TCMs) were involved in the whole treatment process. As an indispensable part of TCM, Chinese patent medicines (CPMs) played an irreplaceable role in the prevention and treatment of this epidemic. Their use has achieved remarkable therapeutic efficacy during the period of medical observation and clinical treatment of mild, moderate, severe, and critical cases and during convalescence. In order to better propagate and make full use of the benefits of TCM in the treatment of COVID-19, this review will summarize the potential target of SARS-CoV-2 as well as the theoretical basis and clinical efficacy of recommended 22 CPMs by the National Health Commission and the Administration of TCM and local provinces or cities in the treatment of COVID-19. Additionally, the study will further analyze the drug composition, potential active ingredients, potential targets, regulated signaling pathways, and possible mechanisms for COVID-19 through anti-inflammatory and immunoregulation, antiviral, improve lung injury, antipyretic and organ protection to provide meaningful information about the clinical application of CPMs.

Liver regional continuous chemotherapy: use of femoral or subclavian artery for percutaneous implantation of catheter-port systems.

AIM: To evaluate the feasibility and safety of the intraarterial chemotherapy of the liver cancer by an interventional method, catheter-port system. METHODS: Thirty-two catheter-port systems were implanted percutaneously via the femoral artery or subclavian artery. Chemotherapies were performed 0-5 d after the implantation of the catheter-port systems. The mean interval between two sequential chemotherapies was 4 wk. The occurrence of side effects of the implantation was examined clinically. RESULTS: Implantation of the catheter-port was successful in all patients. Mean patency period was 210 d. One occlusion (3.1%) of the catheter was observed. Displacement of the catheter was observed in one case (3.1%). One patient rated a hematoma in the chest wall as important. Mild hematoma was reported in 8 cases (25%). In 3 of 32 cases (9.4%), mild pain was reported initially, and dysesthesia was reported in seven (21.9%). No patient rated overall discomfort as mild, severe, or important. CONCLUSION: Percutaneous placement is feasible and safe for liver regional continuous chemotherapy. Compared with surgical placement, the overall complication rate is comparable or less.
