AIM:To investigate the effect of apoptosis stimulation protein 2(ASPP2)on the development of traumatic proliferative vitreoretinopathy(PVR)in a rabbit model.METHODS:A total of 30 New Zealand white rabbits were selected, and the right eyes of all rabbits were inflicted with a scleral penetrating wound of approximately 6 mm. Then rabbits were randomly and evenly divided into experimental and control group. The experimental group received an intravitreal injection of 0.1 mL of ARPE-19 cell suspension transfected with lentivirus-ASPP2, while the control group received an intravitreal injection of 0.1 mL of ARPE-19 cell suspension transfected with negative control lentivirus. At 1, 2, 3, and 4 wk after PVR modeling, a handheld tonometer was used to measure the intraocular pressure. Moreover, fundus photography and ocular ultrasound examination were performed to detect the retinal proliferation. At 4 wk after modeling, hematoxylin-eosin staining was used to observe the morphological retinal changes, and Western blot was used to determine the protein expressions of ASPP2 and the epithelial-mesenchymal transition(EMT)marker Vimentin in the rabbit retinas.RESULTS:At 1, 2, 3, and 4 wk after modeling, there were no significant changes in intraocular pressure within the experimental and control group of rabbit eyes, either before or after PVR modeling, the success rate of PVR modeling in the experimental group was lower than that in the control group(P<0.05), and the retinal proliferation and structural disorder was less severe in the experimental group. At 4 wk after modeling, the retinal protein expression level of ASPP2 in the experimental group was significantly higher than that in the control group(t=3.193, P=0.033), while the Vimentin protein expression level was significantly lower in the experimental group(t=-3.599, P=0.023).CONCLUSION:ASPP2 may be involved in regulating the process of EMT in retinal pigment epithelial cells, thereby delaying the development and progression of traumatic PVR in rabbit eyes.

Knee osteoarthritis (KOA) is a prevalent degenerative joint disease characterized by synovial inflammation, cartilage loss. Often manifesting as joint pain and limited mobility, it severely affects the quality of life of patients. Traditional treatment methods such as pharmacological injections and surgical interventions primarily aim to alleviate symptoms but have limited effects on cartilage repair. Human umbilical cord mesenchymal stem cells (hUC-MSCs), due to their anti-inflammatory and chondrogenic capabilities, is considered a new hope for the treatment of KOA. This article synthesizes the latest research findings from both domestic and international sources to discuss the theoretical basis for the clinical application of hUC-MSCs in treating KOA, clinical study design, and efficacy evaluation. It also addresses the challenges in the clinical application of hUC-MSCs and explores future directions, in the hope of providing feasible theoretical support for the treatment of KOA with hUC-MSCs.

ObjectiveTo investigate the effects of Xixintang (XXT)-medicated serum on the amyloid β-protein (Aβ)25-35-induced polarization of BV-2 microglial cells by a cell experiment and uncover the potential mechanisms of this formula in the prevention and treatment of Alzheimer's disease (AD), thus providing scientific evidence for the clinical application of XXT. MethodsBV-2 microglial cells were subcultured. The optimal concentrations of XXT-medicated serum and Aβ25-35 were determined via the cell-counting kit-8 (CCK-8) assay. The cell experiment was carried out with the following groups: blank control, model (Aβ25-35 at 40 μmol·L-1), XXT-medicated serum (Aβ25-35 at 40 μmol·L-1 + 10% XXT-medicated serum), and blank serum (Aβ25-35 at 40 μmol·L-1 + 10% blank serum). After 24 hours of cell incubation, immunofluorescence was used to detect the expression of ionized calcium-binding adaptor molecule 1 (IBA1), CD16/32, and CD206. Real-time PCR was performed to measure the mRNA levels of CD206, CD163, inducible nitric oxide synthase (iNOS), and arginase 1 (Arg-1). Enzyme-linked immunosorbent assay (ELISA) was employed to quantify the levels of nerve growth factor (NGF), iNOS, and Arg-1. The nitric oxide (NO) concentration was determined via the nitrate reductase method. ResultsCompared with the blank control group, the model group showed increased expression of IBA1 and CD16/32 (P<0.01), decreased expression of CD206 (P<0.05), upregulation in the mRNA level (P<0.01) and content (P<0.05) of iNOS, downregulation in the mRNA levels of CD206, CD163, and Arg-1 (P<0.05, P<0.01), lowered levels of Arg-1 and NGF (P<0.05), and an elevation in the NO level (P<0.05). Compared with the model group, the XXT-medicated serum group exhibited reduced expression of IBA1 and CD16/32 (P<0.05, P<0.01) and increased expression of CD206 (P<0.01). Both the content and mRNA level of iNOS were downregulated (P<0.05, P<0.01), while the mRNA levels of CD206, CD163, and Arg-1 were upregulated (P<0.01) in the XXT-medicated serum group. In addition, the XXT-medicated serum group showed elevated levels of Arg-1 and NGF (P<0.05) and a lowered level of NO (P<0.05). The blank serum group showed no statistically significant differences in the measured parameters compared with the model group. ConclusionThe XXT-medicated serum can inhibit the polarization toward the M1 phenotype and promote the polarization toward the M2 phenotype, exerting anti-inflammatory and neurotrophic effects.

Immobilized enzyme-based enzyme electrode biosensors, characterized by high sensitivity and efficiency, strong specificity, and compact size, demonstrate broad application prospects in life science research, disease diagnosis and monitoring, etc. Immobilization of enzyme is a critical step in determining the performance (stability, sensitivity, and reproducibility) of the biosensors. Random immobilization (physical adsorption, covalent cross-linking, etc.) can easily bring about problems, such as decreased enzyme activity and relatively unstable immobilization. Whereas, directional immobilization utilizing amino acid residue mutation, affinity peptide fusion, or nucleotide-specific binding to restrict the orientation of the enzymes provides new possibilities to solve the problems caused by random immobilization. In this paper, the principles, advantages and disadvantages and the application progress of enzyme electrode biosensors of different directional immobilization strategies for enzyme molecular sensing elements by specific amino acids (lysine, histidine, cysteine, unnatural amino acid) with functional groups introduced based on site-specific mutation, affinity peptides (gold binding peptides, carbon binding peptides, carbohydrate binding domains) fused through genetic engineering, and specific binding between nucleotides and target enzymes (proteins) were reviewed, and the application fields, advantages and limitations of various immobilized enzyme interface characterization techniques were discussed, hoping to provide theoretical and technical guidance for the creation of high-performance enzyme sensing elements and the manufacture of enzyme electrode sensors.

N-acetyl-p-aminophenol (APAP) is an antipyretic analgesic commonly used in clinical practice, and APAP overdose can cause severe liver injury and even death. In recent years, the incidence rate of APAP-induced liver injury (AILI) tends to increase, and it has become the second most common cause of liver transplantation worldwide. Autophagy is a highly conserved catabolic process that removes unwanted cytosolic proteins and organelles through lysosomal degradation to achieve the metabolic needs of cells themselves and the renewal of organelles. A large number of studies have shown that autophagy plays a key role in the pathophysiology of AILI, involving the mechanisms such as APAP protein conjugates, oxidative stress, JNK activation, mitochondrial dysfunction, inflammatory response and apoptosis. This article elaborates on the biological mechanism of autophagy in AILI, in order to provide a theoretical basis for the treatment of AILI and the development of autophagy regulators.

The clinical practice guidelines for Chinese patent medicines (CPM) provide reference for the selection of national drug catalogs, the formulation of prescription collections in medical institutions, and the clinical use of CPM, constituting an important part of traditional Chinese medicine (TCM) guidelines. As a crucial part of Chinese drug supply guarantee system, CPM plays an important role in the treatment, prevention, and healthcare of many disease categories, whereas the application of CPM has problems of misuse and even abuse. To standardize the application of CPM, a research team at Zhejiang Chinese Medical University developed the Reporting Items for Practice Guidelines in Healthcare for Chinese Patent Medicines (RIGHT for CPM) based on the RIGHT checklist framework. The RIGHT for CPM checklist gathers key information from published CPM guidelines, existing TCM reporting checklists, and the RIGHT checklist and its extensions to form an initial pool of reporting items. Seventeen experts from different disciplines were invited to conduct two rounds of Delphi surveys, and the final checklist was reviewed and approved for publication by 18 leading experts in TCM research and guideline reporting from China and abroad. The RIGHT for CPM checklist adds 16 sub-items and revises 2 sub-items on the basis of the RIGHT checklist, highlighting the characteristics of CPM guideline reporting. It considers CPM selection and inclusion criteria, policy access, indications and symptoms, drug combination instructions, drug use in special populations, precautions, and recommendations of Western medical physicians, among others. This can further improve the quality and transparency of CPM guideline reporting, promote standardized reporting of CPM guidelines, and facilitate the rational clinical use of CPM. This article interprets the development process of the RIGHT for CPM checklist and the items that highlight the characteristics of CPM guidelines, with a view to promoting the application of the RIGHT for CPM checklist.
