Simultaneous management of intestinal mucosal barrier dysfunction and gut microbiota dysregulation represents a significant challenge in the treatment of inflammatory bowel disease (IBD). Herein, we report a novel system that integrates multi-enzyme mimicking cerium single-atom nanocatalysts (CeSACs) with Lactobacillus reuteri probiotics (LR@CeSACs) for multipronged management of IBD. In this system, CeSACs demonstrate robust multi-enzyme activities across a broad pH range, effectively scavenging elevated reactive oxygen species, downregulating pro-inflammatory cytokines, and suppressing the expression of fibrosis-related genes. Moreover, probiotics promote the targeting and retention of the CeSACs for sustained catalytic antioxidant therapy. In turn, the inflammation relief enabled by CeSACs promotes bacterial viability, allowing for the rapid reshaping of intestinal barrier function and the restoration of gut microbiota. Therefore, LR@CeSACs exhibit excellent catalytic anti-inflammatory and anti-fibrotic therapeutic effects, as well as a certain prophylactic effect, as demonstrated in several murine models.

Insomnia is a prevalent disorder characterized by difficulties in falling asleep or maintaining sleep.Chronic insomnia can severely impair physical and mental health,as well as quality of life.The traditional Chinese medicine(TCM)theory,"all the eleven zang organs depend on the gallbladder,"is derived from the chapter of Discussion on Six-Plus-Six System and the Manifestations of Organs of Plain Questions.It highlights the pivotal role of the gallbladder in maintaining visceral function.The gallbladder governs decision-making and plays a central role in sleep regulation by modulating spleen-stomach transportation and transformation,dispersing qi movement throughout the body,harmonizing yin and yang,and modulating ying and wei systems.Research has demonstrated that bile acids correspond closely with the gallbladder's TCM functions of"governing the earth zang"and"regulating the eleven zang organs,"serving as a crucial material basis for gallbladder physiology.Dysregulation of bile acid metabolism may contribute to insomnia through multiple pathways,including gastrointestinal dysfunction,disruption of gut microbiota balance,induction of neuroinflammation,and circadian rhythm disturbances.This study proposes that bile acid metabolism disorder may constitute a key pathological mechanism linking gallbladder dysfunction—according to TCM theory—to insomnia.Based on clinical experience,novel therapeutic strategies are proposed under the framework of"regulating the gallbladder to tranquilize mind",including the use of gallbladder-related materials,prioritized application of liver-regulating herbs,and implementation of a sleep rhythm reconstruction protocol.

Hepatocellular carcinoma (HCC) is a type of tumor with a high incidence rate, a low rate of early diagnosis, and poor prognosis, and its development and progression involve many factors. As an important organelle in cells, mitochondria is the "energy factory" of cells and is one of the main sites for the production of reactive oxygen species in vivo, and it also participates in the regulation of cell apoptosis. There are varying degrees of changes in mitochondrial membrane, oxidation respiratory chain, mitochondrial dynamics, mitochondrial DNA, and mitochondrial calcium homeostasis during the development and progression of HCC, and such changes may affect the progression of HCC. This article systematically elaborates on the association between mitochondria and HCC, so as to provide a new direction for the diagnosis and treatment of HCC.

Sodium taurocholate cotransporting polypeptide (NTCP) is not only an important transporter for bile acid absorption into the liver, but also a functional receptor for HBV and HDV, and extensive studies have been performed for its structure, function, gene characteristics, and expression and regulation mechanisms. NTCP is also associated with chronic viral hepatitis, nonalcoholic fatty liver disease, liver fibrosis, primary biliary cholangitis, and hepatocellular carcinoma. This article elaborates on the role of NTCP in various hepatobiliary diseases, so as to provide new direction for the diagnosis and treatment of related diseases.

ObjectiveTo investigate the clinical effect and safety of transcatheter arterial chemoembolization (TACE) combined with microwave ablation (MWA) in the treatment of advanced primary liver cancer. MethodsA total of 186 patients with advanced primary liver cancer who were treated in The Fifth Medical Center of Chinese PLA General Hospital from April 2015 to June 2019 were enrolled and divided into study group and control group using a random number table, with 93 patients in each group. Both groups of patients underwent TACE, and the patients in the study group were treated with ultrasound-guided percutaneous MWA. The two groups were compared in terms of clinical outcome and complications. Quantitative real-time PCR was used to measure the serum level of microRNA-202 (miR-202), ELISA was used to measure the serum levels of fragile histidine triad (FHIT) and P16 protein, and the changes in the above three indices at 3 months after treatment were compared. The two-independent-samples t test was used for comparison of continuous data between two groups, and the paired t-test was used for comparison within one group before and after treatment; The chi-square testwas used for comparison of categorical data between groups. ResultsThe study group had a significantly higher objective response rate than the control group (47.32% vs 27.96%, χ2=7.422, P=0.006), and there was no significant difference in disease control rate between the two groups(P＞0.05). Both groups had significant increases in the serum levels of miR-202, FHIT, and P16 protein at 3 months after treatment (all P＜0.05), and compared with the control group, the study group had significantly higher serum levels of miR-202 (0.84±0.14 vs 0.58±017, t=11.385, P＜0.001), FHIT (1126.35±73.05 pg/ml vs 762.87±56.71 pg/ml, t=37.904, P＜0.001), and P16 protein (52.86±651 pg/ml vs 39.06±5.37 pg/ml, t=15.770, P＜0.001). ConclusionUltrasound-guided MWA in addition to TACE can improve the short-term response of patients with advanced primary liver cancer and increase the serum levels of miR-202, FHIT, and P16 protein, with relatively high safety.

Objective To evaluate the effects on catheter related blood stream infection by different dressing frequency of peripherally inserted central catheter(PICC)with neonates. Methods A systematic review of randomized controlled trials (RCTs) from databases, Data were searched about the transparent dressing replacement frequency for neonatal PICC catheterization. The meta-analysis was performed by using RevMan 5.2 software. Results Nine RCTs were included in a total of 1 730 patients. Meta analysis showed that there was no significant difference in the incidence of PICC puncture dressing, catheter-related infections (including puncture port infection, catheter-related blood flow infection, catheter bacterial colonization) at every 3, 5, and 7 days (P> 0.05). Conclusion the dressing of PICC catheter are replaced will not increase the incidence of catheter-related infections within 7 days, throughout the more appropriate frequency of dressing replacement is once every 7 days.
