ObjectiveTo investigate the therapeutic effect and mechanism of modified Chunzetang on bladder fibrosis and detrusor function in rats with neurogenic bladder urinary retention induced by spinal cord injury. MethodsIn this study, an improved Hassan Shaker spinal cord transection method was used to establish a model of neurogenic bladder urinary retention induced by spinal cord injury, and rats with a spinal cord injury behavior score of 0 were selected for follow-up experiments. The selected rats were randomly divided into a model group (normal saline gavage), low-dose traditional Chinese medicine (TCM) group (gavage of 14.4 g·kg-1 modified Chunzetang), high-dose TCM group (gavage of 28.8 g·kg-1 modified Chunzetang), positive drug group [intraperitoneal injection of 0.05 g·kg-1 nuclear transcription factor-κB (NF-κB) inhibitor pyrrolidine dithiocarbamate (PDTC)], and combination group (intraperitoneal injection of 0.05 g·kg-1 PDTC + gavage of 28.8 g·kg-1 modified Chunzetang). The rats in these groups were administrated with corresponding drugs once a day for four weeks. The BL-420s biofunction acquisition system was used in the experiment to calculate the urodynamic indexes, and the isolated bladder was quickly weighed. The detrusor traction experiment was used to record the minimum bladder contraction tension and frequency in each group. The pathological morphology and tissue fibrosis of detrusor in each group observed by Hematoxycin-eosin (HE) staining and Masson staining were compared. The expression level of α-smooth muscle actin (α-SMA) was detected by immunohistochemistry. Western blot was used to detect the protein expression of NF-κB p65, nuclear transcription factor-κB suppressor protein α (IκBα), transforming growth factor-β1 (TGF-β1), type Ⅰ collagen (ColⅠ), and type Ⅲ collagen (ColⅢ) in bladder tissue of rats in each group. Enzyme-linked immunosorbent assay (ELISA) was used to detect the changes in serum levels of IL-6, IL-1β, and TNF-α. ResultsCompared with that in the sham operation group, the pressure at the urinary leakage point in the model group decreased (P<0.01), and the bladder mass, bladder contractile tension, maximum bladder capacity, and bladder compliance increased (P<0.05,P<0.01). HE staining showed that the arrangement of bladder epithelial cells was disordered, and the pathological manifestations such as mucosa and myometria neutrophil infiltration were obvious. The lamina propria structure was destroyed, and the muscle fiber arrangement was disordered. The interstitial widening and tissue edema were obvious. Masson staining showed that the bladder wall of the model group had more collagen fiber deposition, and the degree of detrusor fibrosis was more severe. The content of detrusor in the visual field was reduced. At the same time, the protein expressions of NF-κB p65, TGF-β1, IκBα, ColⅠ, and ColⅢ in bladder tissue of rats in the model group were significantly increased (P<0.01), and the serum levels of IL-6, IL-1β, and TNF-α were significantly increased (P<0.05). Compared with that in the model group, the pressure at the urinary leakage point in the modified Chunzetang and positive drug groups was increased (P<0.05), and the wet bladder weight, minimum bladder contractile tension, maximum bladder capacity, and bladder compliance were restored (P<0.05, P<0.01). HE and Masson showed that the bladder epithelial cells were relatively neatly arranged, and the structure of the bladder lamina propria was relatively stable. The detrusor bundles were arranged in an orderly manner, and the interstitium was narrow. The degree of tissue edema was relatively low, and the degree of bladder detrusor fibrosis in the modified Chunzetang and positive drug groups was reduced, while the degree of bladder detrusor fibrosis in the positive drug group and combination groups was not obvious. The results of Western blot showed that the expression of NF-κB p65, IκBα, TGF-β1, ColⅠ, and ColⅢ in bladder tissue, as well as the serum levels of IL-6, IL-1β, and TNF-α in modified Chunzetang and positive drug groups were significantly lower, and the expression of bladder tissue-related proteins and the serum levels of IL-6, IL-1β, and TNF-α in the TCM groups decreased significantly with the increase in dose (P<0.05). The results of immunohistochemistry suggested that modified Chunzetang could fully affect the expression of α-SMA in bladder tissue. ConclusionModified Chunzetang can inhibit collagen deposition in bladder tissue of rats with urinary retention induced by spinal cord injury, delay the occurrence and development of bladder fibrosis, and protect the normal contractile function of bladder detrusor, and its mechanism may be related to inhibiting the NF-κB/TGF-β1 signaling pathway, reducing the production of NF-κB p65, IκBα, TGF-β1, ColⅠ, ColⅢ, and other related proteins, and protecting the muscle strength of detrusor.

In recent years, the incidence of dry eye disease(DED)is increasing, positioning it as one of the most prevalent diseases affecting the ocular surface. Inflammatory response is the pathological basis of DED, involving various inflammatory mediators and inflammatory signaling pathways. Consequently, anti-inflammatory treatment emerges as a fundamental strategy for preventing and managing DED. This review summarizes the classic inflammatory factors involved in the development and progression of DED, including interleukins, tumor necrosis factor, matrix metalloproteinases, chemokines, and cell adhesion molecules. It also discusses the relevant inflammatory signaling pathways: the MAPKs pathway, NF-κB pathway, Wnt pathway and TLR pathway. Additionally, this review addresses the mechanisms of action and alterations in relevant biomarkers associated with current first-line recommended anti-inflammatory therapies, including corticosteroids, immunosuppressants, nonsteroidal anti-inflammatory drugs, and traditional Chinese medicine approaches to inflammation management. This comprehensive overview aims to enhance understanding of the inflammatory mechanisms underlying DED while exploring future therapeutic prospects.

Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

[Objective] To analyze the loss rate of platelet donors and evaluate the strategies for establishing a platelet donor bank. [Methods] A total of 1 443 donors who joined the HLA and HPA gene donor bank for platelets in Henan Province from 2018 to 2020 were included in this study. Data on the total number of apheresis platelet donations, annual donation frequency, age at enrollment, donation habits (including the number of platelets donated per session and whether they had previously donated whole blood), and enrollment location were collected from the platelet donor information management system. Donor loss was determined based on the date of their last donation. The loss rates of different groups under various conditions were compared to assess the enrollment strategies. [Results] By the time the platelet bank was officially operational in 2022, 421 donors had been lost, resulting in an loss rate of 29% (421/1 443). By the end of 2023, the overall cumulative loss rate reached 52% (746/1 443). The loss rate was lower than the overall level in groups meeting any of the following conditions: total apheresis platelet donations exceeding 50, annual donation frequency of 10 or more, age at enrollment of 40 years or older, donation of more than a single therapeutic dose per session, or a history of whole blood donation two or more times. Additionally, loss rates varied across different enrollment locations, with higher enrollment numbers generally associated with higher loss rates. [Conclusion] Through a comprehensive analysis of donor loss, our center has adjusted its strategies for establishing the donor pool. These findings also provide valuable insights for other blood collection and supply institutions in building platelet donor banks.

OBJECTIVE To investigate the protective effect and mechanism of saikosaponin C (SSC) on acute liver injury (ALI) in mice induced by carbon tetrachloride (CCl4) based on serum metabolomics. METHODS Forty mice were divided into blank group (water), model group (water), positive control drug group (Biphenyl diester drop pills, 150 mg/kg), and SSC low- and high-dose groups (2.5, 10 mg/kg) using the random number table method, with 8 mice in each group. They were given water/ relevant drugs, once a day, for 7 consecutive days. One hour after the last administration, all mice were intraperitoneally injected with 0.2% CCl4 olive oil to induce ALI model, except for the blank group. After 17 hours of the modeling, the liver index of mice was calculated. The levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and IL-1β in serum of mice were detected. The histopathological changes of liver tissue were observed. Meanwhile, the serum metabolomics of mice were analyzed by liquid chromatography-mass spectrometry. RESULTS Compared with the blank group, the levels of liver index, ALT, AST, LDH, TNF-α, IL-6, and IL-1β in the model group were significantly increased (P<0.01). Hepatocytes were edema, vacuolar degeneration, more necrosis, and a large number of inflammatory cells were infiltrated. Compared with the model group, liver index and serum index levels of mice were significantly decreased (P<0.05 or P<0.01), accompanied by marked improvement in histopathological damage to the liver tissue. The metabolomics results showed that compared with the model group, there were 63 up-regulated and 256 down-regulated differential metabolites in the serum of mice in the SSC high-dose group, including prostaglandin B2, 20-hydroxy-leukotriene B4, 5- hydroxy-L-tryptophan, 7α -hydroxycholesterol, etc.; these metabolites were primarily involved in metabolic pathways such as arachidonic acid metabolism, 5-hydroxytryptamine synapse, primary bile acid biosynthesis. CONCLUSIONS SSC exerts a protective effect against CCl4-induced ALI by down-regulating the level of key metabolites such as prostaglandin B2 and 20-hydroxy-leukotriene B4, and then ruducing metabolic pathways such as arachidonic acid metabolism, 5- hydroxytryptamine synapse, and primary bile acid biosynthesis.
