RESUMO
OBJECTIVE: Observational studies suggested that peripheral blood eosinophils were associated with the risk of nasal polyps. However, these studies did not confirm the causality. This study aims to apply Mendelian randomization (MR) method to comprehensively assess the potential causal association between peripheral blood eosinophils and nasal polyps. METHODS: Genetic instrumental variables were extracted from the largest available genome-wide association study (GWAS) of European participants, which were used to investigate the relationship between peripheral blood eosinophils and nasal polyps. The inverse variance weighted method, the MR Egger method, and the weighted median method were applied for this analysis. MR-Egger intercept tests, leave-one-out analyses, and funnel plots were performed for the sensitivity analysis. RESULTS: With the inverse variance weighted method, the MR analysis suggested that there was a significant difference between peripheral blood eosinophils and the risk of nasal polyps (ukb-a-97, OR 1.004, 95% CI 1.003-1.005, p < 0.001; ukb-a-541, OR 1.005, 95% CI 1.004-1.006, p < 0.001; ukb-b-7211, OR 1.004, 95% CI 1.003-1.005, p < 0.001; ukb-b-8425, OR 1.004, 95% CI 1.003-1.005, p < 0.001; finn-b-J10_NASALPOLYP, OR 3.089, 95% CI 2.537-3.761, p < 0.001). Consistent results were also proved by using the weighted median method and the MR Egger method. CONCLUSIONS: Our findings reveal the causal effect of peripheral blood eosinophils on the increased risk of nasal polyps.

This study aimed to assess the effect of parasternal intercostal block on postoperative wound infection, pain, and length of hospital stay in patients undergoing cardiac surgery. PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, VIP, and Wanfang databases were extensively queried using a computer, and randomised controlled studies (RCTs) from the inception of each database to July 2023 were sought using keywords in English and Chinese language. Literature quality was assessed using Cochrane-recommended tools, and the included data were collated and analysed using Stata 17.0 software for meta-analysis. Ultimately, eight RCTs were included. Meta-analysis revealed that utilising parasternal intercostal block during cardiac surgery significantly reduced postoperative wound pain (standardised mean difference [SMD] = -1.01, 95% confidence intervals [CI]: -1.70 to -0.31, p = 0.005) and significantly shortened hospital stay (SMD = -0.40, 95% CI: -0.77 to -0.04, p = 0.029), though it may increase the risk of wound infection (OR = 5.03, 95% CI:0.58-44.02, p = 0.144); however, the difference was not statistically significant. The application of parasternal intercostal block during cardiac surgery can significantly reduce postoperative pain and shorten hospital stay. This approach is worth considering for clinical implementation. Decisions regarding its adoption should be made in conjunction with the relevant clinical indices and surgeon's experience.
RESUMO
Ultra-weak bioluminescence (UWL) is a physiological phenomenon widely existing in all the biological activities including human, animals, plants, etc., which reflects the energy metabolism of the organism. Since the last century, ultra-weak photon emission (UPE) has been applied to the study of the essence of meridians and acupoints of traditional Chinese medicine and obtained some results as the higher luminescence characteristics, but many problems remain unsolved due to the limitation of detection technology. In recent years, along with the development of bioluminescence signal acquiring system and imaging system, we are able to further explore the characteristics and biological mechanisms of UWL of acupuncture points and meridians in the human body. We proposed to study changes of ultra-weak luminous intensity of acupuncture points and meridians before and after needling stimulation, and the delayed effect of UPE phenomenon, etc., trying to reveal their regularities and essence. In this paper, the prospect of application of UPE to acupuncture research is also discussed by combining newly acquired results of some biological substances of acupoints in experimental studies.
