Objective: To investigate the effects of vitamin B2 (VB2) combined with blue light irradiation on the recovery process and liver function of neonatal jaundice. Method: 150 children with jaundice admitted from May 2024 to October 2025 were selected and randomly divided into a control group and an experimental group using a random number table method, with 75 cases in each group. The conventional group received blue light irradiation treatment, while the experimental group received oral VB2 treatment on the basis of the conventional group. Compare the oxidative stress response of two groups of children [glutathione peroxidase (GSH Px) higher than the control group, 8-hydroxydeoxyguanosine (8-OHdG), advanced protein oxidation products (AOPP), superoxide anion (O2-)], liver microcirculation [von Willebrand factor (vWF), soluble thrombomodulin (sTM), hepatic artery resistance index (HA-RI), portal vein blood flow velocity (PVV)], bilirubin excretion [total bilirubin (TBil), indirect bilirubin (IBil)], liver function [alanine aminotransferase (ALT), aspartate aminotransferase (AST)], rehabilitation process [phototherapy time, bilirubin recovery time to normal, jaundice regression time]. Hospitalization rehabilitation time and treatment safety. Result: After treatment, the GSH Px levels in the experimental group were higher than those in the control group, while 8-OHdG, AOPP, and O2- levels were lower than those in the control group (P<0.05); The vWF, sTM, and HA-RI of the experimental group were lower than those of the control group, while PVV was higher than that of the control group (P<0.05). The TBil, IBil, ALT, and AST of the experimental group were (80.52 ± 5.47) μ mol/L, (68.52 ± 5.49) μ mol/L, (30.25 ± 5.48) U/L, and (32.14 ± 5.22) U/L, respectively, which were lower than those of the conventional group [(85.19 ± 6.44) μ mol/L, (74.37 ± 6.52) μ mol/L, (35.29 ± 6.17) U/L, (38.55 ± 6.48) U/L], and the difference was statistically significant (P<0.05). The phototherapy time, bilirubin recovery time, jaundice resolution time, and hospital rehabilitation time of the experimental group were (3.05 ± 0.33) days, (4.22 ± 1.39) days, (5.41 ± 1.27) days, and (5.12 ± 0.49) days, respectively, which were lower than those of the conventional group [(3.68 ± 0.36) days, (5.36 ± 1.45) days, (6.28 ± 1.33) days, and (6.51 ± 0.54) days], and the difference was statistically significant (P<0.05). The incidence of adverse reactions in the experimental group was not significantly different from that in the control group (P>0.05). Conclusion: VB2 combined with blue light irradiation can alleviate oxidative stress response and improve liver microcirculation in children with jaundice. It has a positive effect on promoting bilirubin excretion and improving liver function, and does not significantly increase treatment risk while promoting the recovery of children. It has high safety and can be further promoted.

Objective To investigate the thermal ablation effect of microbubble ultrasound cavitation combined with microwave ablation on rabbit VX2 tumors. Methods Twenty-four rabbits with liver transplantation tumors were randomly divided into four groups: blank control group, ultrasound-only cavitation treatment group, microwave-only ablation treatment group, and ultrasound-cavitation combined with microwave ablation treatment group. Enhanced ultrasound was used to show the size, shape and contour of the tumor before and after treatment in each group, and the local temperature of the treatment area was detected by a temperature needle. Results The blood flow perfusion defect was the most severe in the combined treatment group. The defect volume of the microwave ablation group and the combined treatment group were 1.53±0.20 and 1.68±0.43 (P=0.117). The temperature reached the plateau time in the microwave ablation group and the combined treatment group. It was (21.7±5.0)s and (10.3±5.0)s (P<0.01), and the highest temperature (℃) was 100.9±5.0 and 134.1±6.0 (P<0.01). Conclusion MWA combined with MEUS for liver cancer can sharply increase the local temperature in the treatment area to the peak temperature, which is expected to improve the treatment effect of liver cancer.

Objective To explore the effect of bile duct ligation induced obstructive cholestasis on rat hepatocytes. Methods Ten Lewis rats were randomly divided into control group and cholestasis group, and the cholestasis was induced by bile duct ligation for 2 weeks. The histopathological changes were compared by H&E and aniline blue staining and the liver function was compared by biochemical analysis. Primary hepatocytes were isolated by modified two-step collagenase perfusion, and the expressions of hepatocyte marker genes, cell proliferation marker genes and cholangiocyte marker genes were detected by RT-qPCR. Results Compared with the control group,the liver of the cholestatic group showed obvious disordered histopathology, deposition of fibrous collagen and impaired liver function. Compared with the control group, the primary hepatocytes in the cholestasis group expressed higher cell proliferation-related genes（Ki67,Foxm1,Pcna and HGF）（P<0. 05）. Primary hepatocytes in the cholestasis group expressed lower levels of hepatocyte marker genes（Alb,Mrp2,Bsep and Catenin1）（P<0. 05）,and higher levels of cholangiocyte marker genes（Ck7,Ck19,Mdr1 and Cftr）（P<0. 05）and higher levels of the hepatic progenitor cell marker genes（Epcam and Sox9）（P<0. 05）. Conclusions Cholestasis induces rat hepatocyte plasticity in the transformation into bile duct properties.
