Objective This article introduced the concrete methods and benefits of promoting and holding competition of acupuncture and moxibustion in TCM universities or colleges. A regular skill competition will not only stimulate students' passion for TCM study and expand teaching methods, but also serve as a effective way to enhance practical skills of students.

Objective To study the correlation between preoperative dye exclusion test and liver function in patients with primary hepatic carcinoma.Methods This was a cross sectional survey.A total of 192 cases of primary liver cancer patients were recruited from May 2014 to March 2015 at the Second Military Medical University Affiliated Eastern Hepatobiliary Surgery Hospital.Hereinto, 160 cases were male and 32 females, the male to female ratio was 5: 1.The age of the patients ranged from 26 to 72 years old, and the average age was 50.5 years old.ICG 15 minutes retention rate of ICG clearance test was determined by PDD method in 192 cases of primary liver cancer patients.ICGR15 value was stratified into three stages: ICGR15 ＜ 10％ , ICGR1510％-20％ , and ICGR15 ＞ 20％.The ICGR15 stage of patients with different ChildPugh grades was analyzed.The biological liver function indexes of patients were simultaneous detected including TBIL, TBA, TP, ALB, PA, ALT, AST, PT-INR, HA, LN, Ⅲ, Ⅳ, APRI, PLT etc.The correlations of ICGR15 and biological indexes of liver function were analyzed using Spearman nonparametric correlation analysis.Results (1) ICGR15 was positively correlated with Child-Pugh grade (r =0.477, P ＜ 0.01) in the 192 cases of HCC.The hierarchical analysis showed that there were significant differences between ICGR15 and different Child-Pugh grades (P ＜ O.05).(2) Child-Pugh classification and ICGR15 comparison further showed that, ICGR15 increased with Child-Pugh grade.While ICG plasma clearance rate (ICGK) and effective hepatic blood flow (EHBF) reduced (P ＜ 0.05).(3) The correlation analysis between ICGR15 and biological indexes of liver function showed that: ICGR15 was positively correlated with TBIL,TBA, ALT, AST, AFU, GGT, PT-INR, HA, LN, Ⅲ, Ⅳ and APRI index [(AST/ULN) × 100/ PLT (× 109/L)] (r =0.422, 0.389, 0.219, 0.301, 0.219, 0.244, 0.325, 0.652,0.403, 0.523, 0.519, 0.434, P ＜ 0.05);and was negatively correlated with TP, ALB, PA, SOD, WBC, PLT (r =-0.290,-0.532, 0.546, 0.531, 0.256, 0.327, P＜ 0.05).Conclusions ICGR15 as a indicator for liver reserved and dynamic function can comprehensively reflect the liver reserve function is associated with the existing Child-Pugh grades and liver function biochemical indexes.Therefore, ICGR15 could be served as a sensitive index reflecting the preoperative liver reserve function.

Objective To understand the relationship between air pollutants and digestive system cancers, and to provide a reference for future research and prevention and control of digestive system cancer. Methods All relevant literature published in English between 1970-2022 was searched through the databases of PubMed, web of science and Embase, and meta-analysis was used to explore the effects of specific air pollutants on digestive system cancers. Results PM_2.5 was able to increase the risk of incidence or mortality of total digestive cancers by 11% (1.05 to 1.17). For specific cancers, PM_2.5 was only associated with an increased risk of liver cancer in this study, with a combined RR (95% CI) of 1.31 (1.19 to 1.46), while there was no statistically significant association with other specific digestive cancers ( P>0.05）. NO2 increased the risk of incidence or mortality of total digestive cancers by 3% (1.00 to 1.07). Conclusion For specific digestive system cancers, PM_2.5 has the most pronounced effect on liver cancer. More evidence is needed to support the relationship between NO₂ and cancer. Currently, it has been observed that NO2 has a negative effect on overall digestive cancers. This study provides insights for the prevention and control of digestive system cancer in countries and regions with high PM_2.5 and NO₂ concentrations.
