Objective:
To observe the clinical efficacy and safety of Yiqi Tongluo Decoction in the intervention of early traditional Chinese medicine (TCM) syndromes after ischemic cerebrovascular disease (ICVD) intervention.
Methods:
From October 2020 to July 2023, a randomized, double-blind, placebo-controlled study was conducted to include 60 patients with qi deficiency, blood stasis, and phlegm obstruction syndrome after ICVD interventional therapy. They were assigned to the Yiqi Tongluo Decoction treatment group (30 cases) and the TCM placebo routine treatment control group (30 cases) according to the randomized block design. Both groups received routine standardized treatment of Western medicine, including dual antiplatelet, lipid regulation, and control of risk factors for cerebrovascular disease. The treatment group was treated with Yiqi Tongluo Decoction based on the control group. The course of treatment was 60 days and follow-up was carried out 2 and 6 months after the operation. The improvement of qi deficiency syndrome, blood stasis syndrome, phlegm syndrome score and TCM syndrome score, modified Rankin score (mRS), Barthel index (BI) score, Fatty acid-binding protein 4 (FABP4) level, incidence of transient ischemic attack (TIA) and ischemic stroke (IS) and incidence of adverse reactions, Head and neck CT angiography (CTA) or digital subtraction angiography (DSA) examination were collected. The clinical efficacy of the patients 2 months after the operation was taken as the main outcome index to preliminarily evaluate the early and long-term efficacy of Yiqi Tongluo Decoction after the ICVD intervention. The early and long-term clinical efficacy and safety of Western medicine standardized treatment combined with TCM Yiqi Tongluo Decoction on patients with qi deficiency, blood stasis and phlegm obstruction syndrome after ICVD intervention were evaluated. The safety of Yiqi Tongluo Decoction in the treatment of patients after ICVD intervention with white blood cell (WBC), C-reactive protein (CRP), fibrinogen (FIB), plasminogen time (PT), recurrence of cerebral ischaemia and restenosis in patients at 2 and 6 months after treatment were evaluated.
Results:
Compared to the control group, the TCM syndrome scores for qi deficiency, blood stasis and phlegm syndrome in the treatment group reduced significantly, the clinical efficacy improved significantly, the mRS score and FABP4 were reduced, and the BI score was increased. Adverse events such as cerebral ischaemia were fewer in the treatment group than in the control group, but the difference was not statistically significant; levels of CRP, WBC and PT were reduced, and levels of FIB were reduced at 6 months post-treatment, all P<0.01, and images were intuitively compared. The treatment group was superior to the control group.
Conclusion
Yiqi Tongluo Decoction combined with Western medicine standard treatment can improve the early clinical efficacy of ICVD patients with qi deficiency, blood stasis and phlegm obstruction syndrome after interventional surgery, improve neurological impairment and daily living ability, reduce the state of qi deficiency syndrome, blood stasis syndrome and phlegm syndrome after interventional surgery, and improve the clinical efficacy of TCM. At the same time, it can reduce the level of FABP4, the target of atherosclerosis and restenosis after interventional surgery, reduce the level of inflammation after interventional surgery in patients with ICVD, regulate coagulation function, and reduce the incidence of long-term recurrence of cerebral ischemia after interventional surgery, with good safety.

BACKGROUND:Degenerative scoliosis is defined as a condition that occurs in adulthood with a coronal cobb angle of the spine>10° accompanied by sagittal deformity and rotational subluxation,which often produces symptoms of spinal cord and nerve compression,such as lumbar pain,lower limb pain,numbness,weakness,and neurogenic claudication.The finite element method is a mechanical analysis technique for computer modelling,which can be used for spinal mechanics research by building digital models that can realistically restore the human spine model and design modifications. OBJECTIVE:To review the application of finite element method in the etiology and treatment of degenerative scoliosis. METHODS:The literature databases CNKI,PubMed,and Web of Science were searched for articles on the application of finite element method in degenerative scoliosis published before October 2023.Search terms were"finite element analysis,biomechanics,stress analysis,degenerative scoliosis,adult spinal deformity"in Chinese and English.Fifty-four papers were finally included. RESULTS AND CONCLUSION:(1)The biomechanical findings from the degenerative scoliosis model constructed using the finite element method were identical to those from the in vivo experimental studies,which proves that the finite element method has a high practical value in degenerative scoliosis.(2)The study of the etiology and treatment of degenerative scoliosis by the finite element method is conducive to the prevention of the occurrence of the scoliosis,slowing down the progress of the scoliosis,the development of a more appropriate treatment plan,the reduction of complications,and the promotion of the patients'surgical operation.(3)The finite element method has gradually evolved from a single bony structure to the inclusion of soft tissues such as muscle ligaments,and the small sample content is increasingly unable to meet the research needs.(4)The finite element method has much room for exploration in degenerative scoliosis.

Clinical and Molecular Hepatology 2025;31(2):409-425
Background/Aims:
Metabolic dysfunction-associated steatohepatitis (MASH) is a significant risk factor for gallstone formation, but mechanisms underlying MASH-related gallstone formation remain unclear. Golgi membrane protein 1 (GOLM1) participates in hepatic cholesterol metabolism and is upregulated in MASH. Here, we aimed to explore the role of GOLM1 in MASH-related gallstone formation.
Methods:
The UK Biobank cohort was used for etiological analysis. GOLM1 knockout (GOLM1-/-) and wild-type (WT) mice were fed with a high-fat diet (HFD). Livers were excised for histology and immunohistochemistry analysis. Gallbladders were collected to calculate incidence of cholesterol gallstones (CGSs). Biles were collected for biliary lipid analysis. HepG2 cells were used to explore underlying mechanisms. Human liver samples were used for clinical validation.
Results:
MASH patients had a greater risk of cholelithiasis. All HFD-fed mice developed MASH, and the incidence of gallstones was 16.7% and 75.0% in GOLM1-/- and WT mice, respectively. GOLM1-/- decreased biliary cholesterol concentration and output. In vivo and in vitro assays confirmed that GOLM1 facilitated cholesterol efflux through upregulating ATP binding cassette transporter subfamily G member 5 (ABCG5). Mechanistically, GOLM1 translocated into nucleus to promote osteopontin (OPN) transcription, thus stimulating ABCG5-mediated cholesterol efflux. Moreover, GOLM1 was upregulated by interleukin-1β (IL-1β) in a dose-dependent manner. Finally, we confirmed that IL-1β, GOLM1, OPN, and ABCG5 were enhanced in livers of MASH patients with CGSs.
Conclusions
In MASH livers, upregulation of GOLM1 by IL-1β increases ABCG5-mediated cholesterol efflux in an OPN-dependent manner, promoting CGS formation. GOLM1 has the potential to be a molecular hub interconnecting MASH and CGSs.

MethodsThe rat's trigeminal neuralgia model was constructed by infraorbital injection of Talci Pulvis, and the rats were randomly divided into the normal group, model group, carbamazepine group (60 mg·kg-1), Cranial Painkiller granules group (2.70 g·kg-1), and low, medium, and high dosage groups of Cranial Painkiller pills' extract powder (1.35, 2.70, 5.40 g·kg-1) according to the basal mechanical pain thresholds, and there were 10 rats in each group. The drug was administered by gavage to each group 2 h after modeling, and distilled water was given by gavage to the normal and model groups under the same conditions once a day for 10 d. Von Frey brushes were used to measure mechanical pain thresholds in rats. Hematoxylin-eosin (HE) staining was used to detect pathological changes in the trigeminal ganglion, and enzyme-linked immunosorbent assay (ELISA) was used to detect the inflammatory factors interleukin-1 (IL-1), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-α (TNF-α) levels in rat serum, as well as neuropeptide substance P (SP) and β-endorphin (β-EP) levels in rat brain tissue. Western blot technique was used to detect the levels of NLRP3, ASC, Caspase-1, and OTULIN proteins in rat brain tissue. ResultsCompared with the normal group, the pain threshold of rats in the model group showed a continuous significant decrease (P<0.01). The pathological damage of brain tissue was significant (P<0.01), and the inflammatory levels of IL-1, IL-6, IL-8, and TNF-α in serum were significantly elevated (P<0.01). The level of the SP in the brain tissue was significantly elevated (P<0.01), and the level of β-EP was significantly reduced (P<0.01), while the level of OTULIN was significantly reduced, and NLRP3, ASC, and Caspase-1 protein levels were significantly elevated (P<0.01). After administration of the drug, compared with the model group, the pain threshold of each dose group of the Cranial Painkiller pills' extract powder and the Cranial Painkiller granules group significantly increased (P<0.01). The inflammatory levels of IL-1, IL-6, IL-8, and TNF-α and SP levels significantly decreased (P<0.01), and the β-EP levels were significantly elevated (P<0.01), while the levels of OTULIN protein were significantly elevated (P<0.05, P<0.01), and the levels of NLRP3, ASC proteins were decreased (P<0.01)in high dose Cranial Painkiller pills' extract powder. Meanwhile, compared with those in the model group, the trigeminal ganglion lesions of rats in the Cranial Painkiller pills' extract powder and Cranial Painkiller granules groups showed different degrees of improvement (P<0.05, P<0.01). ConclusionThe Cranial Painkiller pills' extract powder has significant therapeutic effects on the rat model of trigeminal neuralgia induced by infraorbital injection of Talci Pulvis, and its mechanism is related to the improvement of OTULIN-regulated neuroinflammation.

ObjectiveTo investigate the protective effect and mechanism of verbenalin on mouse mononuclear macrophage leukemia cells (RAW264.7) damaged by human coronavirus (HCoV)-229E infection, thereby providing experimental evidence for its development and application. MethodsRAW264.7 macrophages were infected with different concentrations of HCoV-229E to establish a coronavirus-induced macrophage injury model using the cell counting kit-8 (CCK-8) assay for assessing cell proliferation and viability. Cells were randomly divided into four groups: normal control, verbenalin group (125 μmol·L-1), model group (HCoV-229E), and HCoV-229E + verbenalin group (HCoV-229E + 125 μmol·L-1 verbenalin). Cell viability was measured using the CCK-8 assay, and the maximum non-toxic concentration (CC0), half-maximal cytotoxic concentration (CC50), half-maximal effective concentration (EC50), and selectivity index (SI) of verbenalin were calculated. Calcein/PI double staining was used to assess cell viability and cytotoxicity, and JC-1 staining was applied to evaluate changes in mitochondrial membrane potential (MMP). mito-Keima adenovirus labeling was used to assess mitophagy levels in each group. ResultsA macrophage infection model was successfully established by infecting RAW264.7 cells with the original concentration of HCoV-229E for 36 h. The CC0 of verbenalin was 125 μmol·L-1. The CC50 was 448.25 μmol·L-1. The EC50 against HCoV-229E-infected cells was 46.28 μmol·L-1, and the SI was 9.68. Compared with the normal group, the model group showed significantly reduced cell survival rate (P<0.01), increased cell death rate (P<0.01), decreased MMP (P<0.01), and suppressed mitophagy (P<0.01). In contrast, verbenalin treatment significantly improved cell survival rate (P<0.01), reduced cell death rate (P<0.01), alleviated MMP loss (P<0.01), and enhanced mitophagy levels (P<0.01) compared with the model group. ConclusionVerbenalin can enhance the survival rate of macrophages following HCoV-229E infection. The underlying mechanism may be associated with the activation of mitophagy, maintenance of MMP stability, and alleviation of mitochondrial damage.

ObjectiveThis paper aims to investigate the therapeutic effects of Jidesheng Sheyao tablets on varicella-zoster virus (VZV) and its associated postherpetic neuralgia (PHN) to provide experimental evidence for the clinical application and secondary development of Jidesheng Sheyao tablets. MethodsFifty-six guinea pigs were randomly divided into seven groups according to their body weight, namely the normal group, the model group, the positive control group, the high-dose group, medium-dose group, and low-dose group of Jidesheng Sheyao tablets (1.92, 0.96, 0.48 g·d-1), and the group treated with oral administration combined with topical application of Jidesheng Sheyao tablets (0.96 g·d-1 + 1.2 g·kg-1·d-1). The skin on the back of the guinea pigs in each group was depilated and then abraded with sandpaper. Except for the normal group, 200 μL of VZV solution was dropped on the damaged parts of the back of the guinea pigs in the other groups, and the infection lasted for 2 consecutive days. The drug administration started 2 hours after the infection on the first day and lasted for 7 days. The pathological changes of the back of the guinea pigs in each group were observed every day starting from the second day after the infection. On the 7th day, the guinea pigs were sacrificed by CO2 anesthesia. The locally infected skin was taken, and the viral DNA nucleic acid load was detected by real-time polymerase chain reaction (Real-time PCR). The pathological histology examination was carried out after hematoxylin-eosin (HE) staining. Seventy rats were randomly divided into seven groups according to their body weight, namely the normal group, the model group, the positive control group, the high-dose group, medium-dose group, and low-dose group of Jidesheng Sheyao tablets (1.08, 0.54, 0.27 g·d-1), and the group treated with oral administration combined with topical application of Jidesheng Sheyao tablets (0.54 g·d-1 + 1.2 g·kg-1·d-1). The rats in each group (except the normal group) were subcutaneously inoculated with 50 μL of VZV suspension between the web of the first and second fingers of the left forelimb. The skin on the back of the rats was depilated, and the drug administration started 2 hours after the infection and lasted for 10 days. The mechanical withdrawal threshold of the paws of the rats was detected by a Von Frey filament algometer before inoculation and on the 1st, 3rd, 6th, 8th, and 10th days after inoculation, and the thermal withdrawal reflex latency of the paws of the rats was detected by a hot and cold plate algometer. On the 10th day after the virus inoculation, the rats were anesthetized after the behavioral examination, and the dorsal root ganglia of the spinal cord and spinal cord segments were taken. The contents of substance P (SP), neurokinin (NK), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β) in the dorsal root ganglia of the spinal cord and spinal cord were detected by enzyme-linked immunosorbent assay (ELISA). ResultsCompared with those in the normal group, the guinea pigs in the model group had obvious skin herpes lesions (P<0.01). The viral nucleic acid load was high (P<0.01), and there were disorganized subcutaneous cellular structures and obvious infiltration of inflammatory cells and cell necrosis (P<0.01). The mechanical withdrawal threshold of the paws and the thermal withdrawal reflex latency of the paws of the rats were significantly decreased (P<0.05), and the contents of NK, SP, TNF-α, and IL-1β in the dorsal root ganglia of the spinal cord and spinal cord of the rats were significantly increased (P<0.01). Compared with the model group, the high-dose and medium-dose groups of topical administration of Jidesheng Sheyao tablets and the group of oral administration combined with topical application could significantly improve the lesions such as skin redness and herpes of the guinea pigs caused by VZV infection (P<0.01), reduce the VZV viral nucleic acid load in the skin tissues of the guinea pigs (P<0.01), alleviate the degree of inflammatory cell infiltration and skin cell necrosis in the skin tissue (P<0.05), significantly increase the mechanical withdrawal threshold of the paws and the thermal withdrawal reflex latency of the paws of the rats (P<0.05), and decrease the contents of NK, SP, TNF-α, and IL-1β in the dorsal root ganglia of the spinal cord and spinal cord of the rats (P<0.01). ConclusionJidesheng Sheyao tablets demonstrated significant therapeutic effects on VZV-induced skin infections and postherpetic neuralgia (PHN), providing a promising candidate for the prevention and treatment of VZV infections.

ObjectiveTo construct an animal model of respiratory syncytial virus(RSV)-infected pneumonia suitable for preclinical studies. MethodsThe virulence of RSV to the four cell lines was observed by cytopathic effect (CPE), and 50% tissue culture infective dose(TCID50) was calculated. Twenty BALB/c mice were randomly divided into a normal group and a model group. Six BALB/c-hIGF1R mice served as the humanized IGF1R model group. Except for the normal group, the other groups received intranasal RSV infection on days 1 and 3 to establish a viral pneumonia model. The efficacy of establishing an RSV-induced pneumonia animal model based on humanized insulin-like growth factor 1 receptor (IGF1R) mice was evaluated by measuring organ indices, peripheral blood lymphocyte percentages, pulmonary pathology and imaging, and pulmonary viral load. Additionally, ten BALB/c mice served as normal group, and thirty-two BALB/c-hIGF1R mice were randomly assigned to humanized IGF1R model group, ribavirin group (82.5 mg·kg-¹·d-¹), and high and low dose groups of Lianhua Qingwen (3.3 mg·kg-¹·d-¹ , 1.65 mg·kg-¹·d-¹), with 8 mice per group. The viral load in lung tissue was measured after ribavirin and Lianhua Qingwen intervention, and the model was applied to the evaluation of anti-RSV drugs. ResultsIn the lungs of the humanized IGF1R model group, large solid and diffuse ground-glass shadows were seen, and the lung volume was significantly increased (P<0.01). The lung index was significantly increased (P<0.01), and both the spleen index and thymus index were significantly decreased (P<0.01). The percentages of CD3+ and CD4+T cells were significantly decreased (P<0.05), and there was a large amount of inflammation and stasis in the perivascular area of the lung tissue, which was predominantly characterized by lymphocytes. The endothelium of blood vessels was partially detached, with a small number of eosinophils. After infecting BALB/c-hIGF1R mice with RSV, the expression of viral nucleic acids in the lung tissue of the mice was significantly increased, with significant differences compared with the normal group (P<0.01). The expression of viral nucleic acids in the ribavirin group and the high and low dose groups of Lianhua Qingwen was significantly reduced, with significant differences compared with the normal group (P<0.01). ConclusionHumanized IGF1R mice are more susceptible to respiratory SVC, and the animal model of RSV-infected pneumonia based on humanized IGF1R mice was successfully constructed, which is suitable for the evaluation of anti-RSV drugs.
