Neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) is an autosomal recessive disease caused by SLC25A13 gene mutations, and is characterized by delayed jaundice clearance, liver dysfunction, and elevated aminoacidemia. The confirmed diagnosis depends on gene analysis. Citrin deficiency is one of the important causes of neonatal intrahepatic cholestasis in China. Recently more and more researches about NICCD were reported. The paper summarized the epidemiology, pathogenesis, clinical characteristics, and progresses in diagnosis and treatment of NICCD.

Oxidative stress is a redox imbalance in the body, which is one of the important factors leading to tissue damage and diseases. The nuclear factor E2-related factor 2 (Nrf2)-Kelch like ECH-associated protein 1 (Keap1) signaling pathway is not only an important defense system against oxidative damage, but also one of the key signaling pathways of the antioxidant capacity. Numerous studies have shown that targeting the Keap1-Nrf2 signaling pathway to activate Nrf2 has become an effective strategy for the treatment of oxidative stress and related diseases. Using small molecules to directly block the Keap1-Nrf2 protein-protein interaction (PPI) is one of the important directions for activating Nrf2 and exerting the cytoprotective effect, which can avoid the potential side effects of covalent modification of Nrf2. On the other hand, the Keap1 is an efficient E3 ubiquitin ligase that has been used in the design of proteolysis targeting chimeras (PROTACs). This review summarizes the research progresses of Keap1-Nrf2 protein interaction inhibitors and degraders based on the Keap1 E3 ubiquitination system in recent years.

Correlation between the intrahepatic inflammatory pathogenesis and the TCM theory of liver collateral injury by toxins in patients of type 2 diabetes mellitus (T2DM) with insulin resistance (IR) was investigated, to elucidate that removing toxins, dredging collateral and modulating Gan could be one of the effective approaches for inhibiting intrahepatic inflammation mechanism of T2DM with IR.

Objective: This study aimed to evaluate the effects of 2 endoscopic spine surgeries on the biomechanical properties of normal and osteoporotic spines. Methods: Based on computed tomography images of a healthy adult volunteer, 6 finite element models were created. After validating the normal intact model, a concentrated force of 400 N and a moment of 7.5 Nm were exerted on the upper surface of L3 to simulate 6 physiological activities of the spine. Five types of indices were used to assess the biomechanical properties of the 6 models, range of motion (ROM), maximum displacement value, intervertebral disc stress, maximum stress value, and articular protrusion stress, and by combining them with finite element stress cloud. Results: In normal and osteoporotic spines, there was no meaningful change in ROM or disc stress in the 2 surgical models for the 6 motion states. Model N1 (osteoporotic percutaneous transforaminal endoscopic discectomy model) showed a decrease in maximum displacement value of 20.28% in right lateral bending. Model M2 (unilateral biportal endoscopic model) increased maximum displacement values of 16.88% and 17.82% during left and right lateral bending, respectively. The maximum stress value of L4–5 increased by 11.72% for model M2 during left rotation. In addition, using the same surgical approach, ROM, maximum displacement values, disc stress, and maximum stress values were more significant in the osteoporotic model than in the normal model. Conclusion In both normal and osteoporotic spines, both surgical approaches were less disruptive to the physiologic structure of the spine. Furthermore, using the same endoscopic spine surgery, normal spine biomechanical properties are superior to osteoporotic spines.

PURPOSE: The aim of the study was to evaluate the efficacy and safety of combining sorafenib with chemotherapy in patients with human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer. METHODS: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, American Society for Clinical Oncology abstracts, and European Society for Medical Oncology abstracts were searched. Randomized clinical trials that compared the efficacy and safety of sorafenib plus chemotherapy in patients with HER2-negative advanced breast cancer with placebo plus chemotherapy were eligible. The endpoints were progression-free survival (PFS), overall survival (OS), time to progression (TTP), duration of response (DOR), overall response rate (ORR), clinical benefits, and adverse effects. The meta-analysis was performed using Review Manager 5.2.6 (The Nordic Cochrane Centre), and the fixed-effect model weighted by the Mantel-Haenszel method was used. When considerable heterogeneity was found (p<0.1), further analysis (subgroup analysis, sensitivity analysis, or random-effect model) was performed to identify the potential cause. The results are expressed as hazard ratios or risk ratios, with their corresponding 95% confidence intervals. RESULTS: The final analysis included four trials comprising 844 patients. The results revealed longer PFS and TTP, and higher ORR and clinical benefit rates in patients receiving sorafenib combined with chemotherapy compared to those receiving chemotherapy and placebo. OS and DOR were similar in the two groups. Meanwhile, the incidence of some adverse effects, including hand-foot skin reaction/hand-foot syndrome, diarrhea, rash, and hypertension, were significantly higher in the sorafenib arm. CONCLUSION: Sorafenib combined with chemotherapy may prolong PFS and TTP. This treatment was associated with manageable toxicities, but frequent dose interruptions and reductions were required.
