Objective To evaluate the effect of liver function on liver enhancement in hepatobiliary phase of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid(Gd-EOB-DTPA)-enhanced MRI.Methods Sixty-seven patients who suffered from cirrhosis and received enhanced MRI with Gd-EOB-DTPA were retrospectively analyzed,and divided into three subgroups according to ChildPugh score(45 patients in group A,20 in group B,5 in group C).All the individuals of both groups had MRI before injection,and hepatobiliary phase images were obtained at 5,10,and 20 minutes after bolus administration of Gd-EOB-DTPA.The relative enhancement(RE) was calculated by dividing the signal intensity of liver(SI) at t min after injection(SIt) by precontrast SI(SI0).The total serum bilirubin level(TB),serum albumin level(Alb) and prothrombin time(PT) were recorded.The one-way ANOVA was used to compare the RE among three groups at 5,10 and 20 minutes.SNK was used for further pairwise comparison.The effect of liver function on RE was assessed with the generalized linear model.Pearson correlation coefficients were measured between each biochemical test result(TB,Alb,PT) and RE at different time points.Results The RE at 5,10 and 20 minutes were 1.59±0.20,1.65±0.22,1.69±0.25 of group A; 1.47± 0.14,1.48±0.18,1.50±0.22 of group B,1.35±0.07,1.27±0.06,1.26±0.06 of group C.There were statistically significant differences of RE among groups at 5,10 and 20 minutes(F=5.854,11.207,9.666,P＜0.01).Statistically pairwise comparison differences of RE were found between group A and C at 5,10 and 20 minutes(P＜0.01),between B and C at 10 and 20 minutes(P＜0.05),between A and B at 10 minutes(P＜ 0.05).There were statistically significant differences of TB,Alb and PT among groups(P＜0.01).RE at 10 and 20 minutes had moderate negative correlation with TB(r=-0.483,-0.500; P＜0.01),low negative correlation with PT(r=-0.326,-0.351;P＜0.01) and weak positive correlation with Alb(r=0.290,0.292;P＜0.05).Conclusions There are differences of RE among patients with different liver function,and the RE is associated with TB,Alb and PT.Thus,it may allow us to estimate the liver function.

- () is the earliest and existed well-known work on acupuncture and moxibustion, with irreplaceable literature values and huge impacts on the later generations. Feiyang (BL 58) is the -connecting point of the bladder meridian and recorded 11 times in -. This book is the representative for the exploration on the acupoint nomenclature and clinical connotation. Through the investigation on the textual connotation of the specified terms and the alias of Feiyang (BL 58), it was discovered that the nomenclature of this acupoint was based on the main symptoms, the characters of the running course of meridian and acupuncture effects. It was proved that the unique property of this acupoint was as rising, dispersing and flying of meridian . In comparison of -- () of the printed edition of the Dynasty version and - (), it was found that the indications and connotation of Feiyang (BL 58) were more extensively richer than the records in teaching materials. Those study results contribute to the extension of the clinical application of this acupoint.

Neoadjuvant chemoradiotherapy (nCRT) followed by total mesorectal excision (TME) and adjuvant chemotherapy serves as a traditional standard treatment for locally advanced rectal cancer (LARC). However, such treatment suffers low pathological complete response (pCR) rates, which are merely less than 15%, and low anal-preservation rates, failing to meet the demand of patients for high quality of life. Recently, total neoadjuvant therapy (TNT) whereby postoperative adjuvant chemotherapy is performed preoperatively has further increased the pCR rate, gradually becoming a novel therapeutic approach. Nevertheless, the pCR rate of TNT remains below 30%. Presently, immune checkpoint inhibitors (ICIs) have been proved to be highly successful in treating various solid tumors, yet they are scarcely employed to treat LARC. In recent years, many clinical trials have been conducted to explore the application of nCRT combined with ICIs in the treatment of LARC. This paper reviews the advances in research on this therapy.

Radiomics,as a noninvasive method of image analysis,had been confirmed through numerous studies in predictive value for esophageal cancer in staging,treatment response and radiation pneumonia.The research background of radiomics,its clinical application,challenges,and future research direction in esophageal cancer were summarized in this review.
