ObjectiveTo investigate the effect of Danggui Shaoyaosan on the expression of Toll-like receptor 4/nuclear factor-kappa B p65/NOD-like receptor protein 3 (TLR4/NF-κB p65/NLRP3) signaling pathway in the renal tissues of db/db mice with spontaneous diabetes, and to explore the potential mechanism by which Danggui Shaoyaosan alleviates inflammation in diabetic kidney disease (DKD). MethodsThirty db/db mice were divided into five groups: A model group, Danggui Shaoyaosan low- (16.77 g·kg-1·d-1), medium- (33.54 g·kg-1·d-1), and high-dose (67.08 g·kg-1·d-1) intervention groups, as well as an irbesartan group (0.025 g·kg-1·d-1) by the random number table method, with 6 mice in each group. Additionally, 6 db/m mice were assigned to the normal group. After 8 weeks of intervention, the following parameters were determined by corresponding methods: body weight, fasting blood glucose (FBG), 24-hour urinary protein (24 h-UTP), and serum creatinine (SCr) levels, renal histopathological analysis by hematoxylin-eosin (HE) staining, Masson staining, and periodic acid-Schiff (PAS) staining, the protein and mRNA expression levels of TLR4, NF-κB p65, NLRP3, tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-10 (IL-10), and interleukin-18 (IL-18) by Western blot and Real-time quantitative polymerase chain reaction (Real-time PCR), as well as TLR4, NF-κB p65, and NLRP3 protein expression in renal tissues by immunohistochemistry (IHC). ResultsCompared with the normal group, the model group exhibited increased body weight, FBG, 24 h-UTP, and SCr levels (P<0.05); disordered renal structure, thickened basement membrane, and interstitial inflammatory cell infiltration, elevated TLR4, NF-κB p65, NLRP3, TNF-α, IL-1β, IL-6, and IL-18 expression; as well as decreased IL-10 expression (P<0.05). Compared with the model group, these pathological changes and biochemical abnormalities were reversed in the medicine intervention groups to varying degrees (P<0.05). ConclusionDanggui Shaoyaosan may delay DKD progression by alleviating renal inflammatory response and reducing urinary protein excretion via modulating the TLR4/NF-κB p65/NLRP3 signaling pathway.

Neurological diseases have high morbidity and disability rates, posing a severe threat to human health. Cli nical manifestations include motor, sensory, cognitive and conscious disorders. Chaihu jia longgu muli decoction is derived from Treatise on Febrile Diseases , with the effects of harmonizing Shaoyang, activating Yang and clearing heat, and tranquilizing the mind. This paper systematically reviews the research progress in clinical application and mechanism of Chaihu jia longgu muli decoction in the field of neurological diseases. It has been found that the decoction shows favorable efficacy in various neurological diseases such as insomnia, depression, epilepsy, vertigo, migraine and vascular dementia. The specific mechanisms are related to regulating neurotransmitter levels, repairing neuronal function, alleviating neuroinflammation, improving mitochondrial dysfunction and regulating intestinal flora. In the future, standardized prospective follow-up cohorts should be established, and core outcome indicators should be clearly defined to strengthen the evidence base. Furthermore, multidisciplinary research should be leveraged to expand the therapeutic value of Chaihu jia longgu muli decoction in the management of neurological diseases.

BACKGROUND:
The use of potentially inappropriate medications (PIMs) is a major concern for medication safety as it may entail more harm than potential benefits for older adults. This study aimed to explore the prescribing rate, healthcare utilization, and expenditure of older adults using PIMs in China.
METHODS:
A cross-sectional analysis was conducted using a national representative database of all medical insurance beneficiaries across China, extracting ambulatory visit records of adults aged 65 years and above between 2015 and 2017. Descriptive analysis was conducted to measure the rate of patients exposed to PIM, prescribing rate of each PIM, average annual outpatient visits per patient, average total medication costs for each visit, average annual cost of PIMs for each patient, and average annual medication costs for each patient. Generalized linear model with logit link function and binomial distribution was used to examine the adjusted associations between PIMs and independent variables.
RESULTS:
In total, 845,278 (33.2%) participants were identified to be exposed to at least one PIM. Patients aged 75-84 years (38.1%, 969,809/2,545,430) and ≥85 years (37.9%, 964,718/2,545,430) were more likely to be prescribed with PIMs. Beneficiaries of the Urban Employee Basic Medical Insurance (UEBMI) and living in eastern and southern regions were more frequently prescribed with PIMs. Compared with patients without PIM exposure (7.5 visits, drug cost of RMB 1545.0 Yuan), patients with PIM exposure showed higher adjusted average annual number of outpatient visits (10.7 visits, β = 3.228, 95% confidence interval [CI] = 3.196-3.261) and higher annual drug costs (RMB 2461.8 Yuan, Coef. = 916.864, 95% CI = RMB 906.292-927.436 Yuan).
CONCLUSIONS
The results showed that the use of PIM among older adults was common in China. This study suggests that the use of PIM could be considered as a clear target, pending multidimensional efforts, to promote rational prescribing for older adults.

Objective:To investigate the role of ubiquitin-specific protease 21 (USP21) in enterovirus group A type 71 (EV-A71) infection.Methods:Peripheral blood mononuclear cells (PBMC) were obtained from a cohort of 24 children infected with EV-A71 and 24 healthy children. Expression of USP21 was determined by real-time fluorescence quantitative PCR (qPCR). Additionally, the impact of USP21 overexpression or knockout on EV-A71 replication was evaluated using a combination of qPCR and western blot (WB) analysis. Furthermore, WB was employed to measure the levels of EV-A71 structural protein VP1, phosphorylated interferon regulatory factor 3 (IRF3) and other key molecules in the RIG-I-like receptor (RLR) signaling pathway. Co-immunoprecipitation (Co-IP) was utilized to investigate the effects of USP21 on the ubiquitin levels of EV-A71 nonstructural protein 2A protease (2A pro). Results:In comparison to healthy children, the expression of USP21 mRNA in PBMC of children infected with EV-A71 was notably elevated. The overexpression of USP21 significantly enhanced the cytopathic effects induced by EV-A71, upregulated levels of VP1 mRNA and protein, and facilitated EV-A71 replication, leading to a decrease in cell activity with increasing levels of USP21 transfection. Following the knockout of the USP21 gene, the VP1 mRNA levels were significantly declined in comparison to the control group. Furthermore, the overexpression of USP21 was found to have no impact on the transcriptional activity of EV-A71 2A pro. However, it was observed to enhance the expression of 2A pro protein, reduce the ubiquitination of 2A pro, suppress the protein levels of mitochondrial antiviral signaling protein (MAVS) and melanoma differentiation-associated gene 5 (MDA5), as well as decrease the phosphorylation of IRF3. Additionally, the induction of IFN-β mRNA by EV-A71 infection was downregulated. Conclusions:USP21 has been shown to enhance the replication of EV-A71 through the downregulation of 2A pro ubiquitination, suppression of MAVS and MDA5 protein expression, and inhibition of the interferon signaling pathway.

ObjectiveTo evaluate the clinical efficacy of Xu's Shenqiyizhu (SQYZ) decoction combined with chemotherapy in the treatment of cancer-related fatigue (CRF) of stagnated-toxin spleen deficiency type after gastric cancer surgery and explore its possible mechanism. MethodsFifty postoperative gastric cancer patients with CRF of stagnated-toxin spleen deficiency type were selected and randomly divided into an experimental group and a control group by using a random number table,with 25 cases in each group. The control group was treated with FLOT chemotherapy (50 mg·m-2 docetaxel (iv drip on day 1) + 85 mg·m-2 oxaliplatin (iv drip on day 1) + 200 mg·m-2 calcium folinate (iv drip on day 1) + 2 600 mg·m-2 fluorouracil (iv drip for 24 h on day 1),once every three weeks) and basic and symptomatic supportive treatment. The experimental group was treated with Xu's SQYZ decoction (decocted twice,200 mL taken orally twice a day) in addition to the treatment of the control group. One course of treatment lasted for three weeks,with a total of four courses conducted. Observation was performed on the piper fatigue scale (PFS) scores,karnofsky performance status (KPS) scores,European Organization for Research and Treatment of cancer quality of life questionnaire (EORTC QLQ-C30) scores,traditional Chinese medicine syndrome scores,and serum levels of tumor necrosis factor-α (TNF-α),interferon-γ (IFN-γ),and interleukin-6 (IL-6)detected via enzyme linked immunosorbent assay (ELISA) before and after treatment in the two groups. The safety test results before and after treatment for the two groups of patients,as well as the occurrence of adverse events during treatment, were recorded. Transcriptome sequencing data of peripheral blood samples from gastric adenocarcinoma patients and normal individuals were downloaded from the gene expression omnibus (GEO) database,and differentially expressed genes between the tumor and normal groups were identified. Differential gene enrichment analysis was made based on the Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO). The CRF relevance scores of genes were retrieved from the GeneCards database. Results① Compared with that before treatment,the total PFS score in the experimental group was significantly reduced (P<0.05). Compared with the control group after treatment,the experimental group showed significantly reduced total PFS score (P<0.05). ② Compared with that before treatment,the KPS score in the experimental group decreased significantly (P<0.05). Compared with the control group after treatment,the experimental group exhibited a significantly decreased KPS score (P<0.05). The experimental group demonstrated significantly increased functional scores (physical function,role function,emotional function,social function,and overall health) (P<0.05) and significantly reduced symptom scores (fatigue,shortness of breath,loss of appetite,constipation,and diarrhea) of the EORTC QLQ-C30 scale after treatment compared with before treatment. Compared with the control group after treatment,the experimental group presented significantly increased functional scores (physical function,emotional function,social function,and overall health) (P<0.05) and significantly reduced symptom scores (fatigue,nausea and vomiting,shortness of breath,loss of appetite,and diarrhea) of the EORTC QLQ-C30 scale (P<0.05). Compared with those before treatment,the traditional Chinese medicine syndrome scores (eating too little and poor digestion,fatigue and weakness,postprandial bloating,abnormal bowel movements,lassitude and weakness,and total score) in the experimental group were significantly reduced (P<0.05). Compared with the control group after treatment,the experimental group had significantly reduced traditional Chinese medicine syndrome scores (eating too little and poor digestion,fatigue and weakness,nausea and vomiting,and sallow complexion) (P<0.05), which indicated better efficacy in the experimental group than in the control group (χ2=7.996,P<0.05). The serum levels of TNF-α,IL-6,and IFN-γ were significantly correlated with each other (P<0.01). Compared with those before treatment,the levels of serum cytokines TNF-α,IL-6,and IFN-γ in the experimental group were significantly reduced (P<0.05). Compared with the control group after treatment,the experimental group showed significantly reduced serum levels of cytokines TNF-α,IL-6,and IFN-γ (P<0.05). ③ There were no significant intra-group and inter-group differences in the safety test results of the two groups before and after treatment. During the treatment period,there was no significant difference in the incidence of adverse reactions between the two groups of patients. ④ Compared with the normal group,the tumor group exhibited a total of 328 significantly up-regulated genes in the peripheral blood (P<0.05),and KEGG and GO analyses showed that they were significantly enriched in signaling pathways such as TNF (P<0.05). ⑤ TNF,IL6,IFNG, and other cytokine encoding genes may be key pathogenic genes for CRF. ConclusionXu's SQYZ decoction can alleviate symptoms such as fatigue in postoperative chemotherapy patients with gastric cancer and improve their functional status and quality of life. Its mechanism may be related to improving cytokine imbalance.

As a common medical condition, vertigo can be induced by multiple diseases in the modern medical system. Its incidence rate shows an upward trend with the increase in age. According to the theory of mutual interference between clear Qi and turbid Qi in Huangdi's Internal Classic (Huang Di Nei Jing), this paper systematically analyzes the pathogenesis of vertigo and explores the mechanism and clinical application value of Xiao Chaihutang in the treatment of vertigo. It is believed that the mutual inference between clear Qi and turbid Qi leads to the failure of clear Yang to ascend, resulting in the lack of nourishment for the brain and the inability of turbid Yin to descend, which disturbs the clear orifices, thus causing vertigo. The core pathogenesis lies in the dysfunction of Qi movement, the disorder of body fluid distribution, and the imbalance between Yin and Yang. The compatibility of Xiao Chaihutang takes into account the methods of pungent medicinal materials opening and bitter medicinal materials descending, tonifying deficiency and purging excess, and regulating Qi movement. This prescription can regulate the pathological state of the mutual interference between clear Qi and turbid Qi from three aspects: regulating Qi movement throughout the body, harmonizing the distribution of body fluids, and coordinating Yin and Yang as well as the interior and exterior, thus preventing and treating vertigo. Modern research findings show that Xiao Chaihutang can improve hemodynamics to promote cerebral blood circulation and has anti-inflammation, immunomodulatory, and anti-tumor functions, which correspond to the therapeutic effects of Xiao Chaihutang under the theory of mutual interference between clear Qi and turbid Qi. The decoction exerts therapeutic effects on vertigo caused by hypertension, stroke, otitis media, Meniere’s disease, and brain tumor as well as benign paroxysmal positional vertigo. Further exploration of the theoretical connotation of mutual inference between clear Qi and turbid Qi and analysis of the pathogenesis of vertigo and the therapeutic effect of Xiao Chaihutang can better interpret the internal correlations among the three, thus providing new ideas for the syndrome differentiation and treatment of vertigo.
