OBJECTIVE To investigate the effects and mechanisms of Lycium ruthenicum Murr. in improving sleep. METHODS Network pharmacology was employed to identify the active components of L. ruthenicum and their associated disease targets, followed by enrichment analysis. A caffeine‑induced zebrafish model of sleep deprivation was established , and the zebrafish were treated with L. ruthenicum Murr. extract (LRME) at concentrations of 0.1, 0.2 and 0.4 mg/mL, respectively; 24 h later, behavioral changes of zebrafish and pathological alterations in brain neurons were subsequently observed. The levels of inflammatory factors [interleukin-6 (IL-6), IL-1β, IL-10, tumor necrosis factor-α (TNF-α)], oxidative stress markers [superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), catalase (CAT)], and neurotransmitters [5- hydroxytryptamine (5-HT), γ-aminobutyric acid (GABA), glutamic acid (Glu), dopamine (DA), and norepinephrine (NE)] were measured. The protein expression levels of protein kinase B1 (AKT1), phosphorylated AKT1 (p-AKT1), epidermal growth factor receptor (EGFR), B-cell lymphoma 2 (Bcl-2), sarcoma proto-oncogene,non-receptor tyrosine kinase (SRC), and heat shock protein 90α family class A member 1 (HSP90AA1) in the zebrafish were also determined. RESULTS A total of 12 active components and 176 intersecting disease targets were identified through network pharmacology analysis. Among these, apigenin, naringenin and others were recognized as core active compounds, while AKT1, EGFR and others served as key targets; EGFR tyrosine kinase inhibitor resistance signaling pathway was identified as the critical pathway. The sleep improvement rates in zebrafish of LRME low-, medium-, and high-dose groups were 54.60%, 69.03% and 77.97%, 开发。E-mail:hjp_yft@163.com respectively, while the inhibition ratios of locomotor distance were 0.57, 0.83 and 0.95, respectively. Compared with the model group, the number of resting counts, resting time and resting distance were significantly increased/extended in LRME medium- and high-dose groups (P<0.05). Neuronal damage in the brain was alleviated. Additionally, the levels of IL-6, IL-1β, TNF-α, MDA, Glu, DA and NE, as well as the protein expression levels of AKT1, p-AKT1, EGFR, SRC and HSP90AA1, were markedly reduced (P<0.05), while the levels of IL-10, SOD, GSH-Px, CAT, 5-HT and GABA, as well as Bcl-2 protein expression, were significantly elevated (P<0.05). CONCLUSIONS L. ruthenicum Murr. demonstrates sleep-improving effects, and its specific mechanism may be related to the regulation of inflammatory responses, oxidative stress, neurotransmitter balance, and the EGFR tyrosine kinase inhibitor resistance signaling pathway.

OBJECTIVE To analyze the safety and efficacy of vonoprazan (VPZ) in the treatment of peptic ulcer (PU) and post-endoscopic submucosal dissection (ESD) ulcers, providing evidence-based pharmaceutical evidence for clinical practice and medical decision-making. METHODS Retrieved from CNKI, Wanfang, VIP, CBM, PubMed, Embase, Web of Science, and the Cochrane Library, meta-analyses/systematic reviews related to VPZ in the treatment of PU and post-ESD ulcers were collected. Two researchers independently performed literature screening, data extraction, quality assessment of included studies, and evaluation of literature overlap. By employing the umbrella review analysis, a fresh meta-analysis was conducted on all relevant raw research data when a high degree of overlap was identified among the included studies. RESULTS A total of 17 meta-analyses were included, with quality ranging from high to very low; all outcome measures involved showed a very high level of overlap in the included meta-analyses (corrected covered area: 22.22%-100%). In the treatment of post-ESD ulcers, compared to proton pump inhibitor (PPI), VPZ significantly improved the ulcer healing rate at 4 weeks post-ESD [RR=1.27, 95%CI (1.03, 1.56), Z=2.21, P= 0.027] and the ulcer contraction rate post-ESD [MD=0.08, 95%CI (0.00, 0.16), Z=2.09, P=0.037], while significantly reducing the ulcer recurrence rate in patients with a history of PU [RR=0.49, 95%CI (0.32, 0.73), Z=3.49, P=0.001]; the delayed bleeding rate in the VPZ group was significantly lower than that in the lansoprazole subgroup [RR=0.47, 95%CI (0.25, 0.90), Z=2.28, P=0.02]. In the treatment of PU, the incidence of adverse events with VPZ was significantly higher than that with PPI in the duodenal ulcer subgroup [RR=1.13, 95%CI (1.02, 1.26), Z=2.38, P=0.017]. CONCLUSIONS For post-ESD ulcers, VPZ demonstrates superior therapeutic efficacy compared to PPI and can reduce ulcer recurrence rates in patients with a history of PU. However, it does not offer advantages in terms of safety for duodenal ulcer treatment.

OBJECTIVE To investigate the efficacy and safety of omadacycline in the treatment of macrolide-unresponsive Mycoplasma pneumoniae pneumonia (MUMPP) in children. METHODS A retrospective study was conducted on children aged 1-18 years old with MUMPP who were hospitalized in the Department of Pediatrics, the First Affiliated Hospital of Xinjiang Medical University from January 2022 to June 2025. According to the selection of secondary antibiotics after 72 h of initial treatment with macrolides, they were divided into the omadacycline group and the doxycycline group. Based on conventional treatment, children in the omadacycline group were given intravenous infusion of 2.4 mg/kg (once daily) of omadacycline tosylate, while children in the doxycycline group were given oral doxycycline hydrochloride tablets at 2 mg/kg (twice daily). The efficacy and safety were compared between the two groups of pediatric patients. Univariate analysis and multivariate Logistic regression analysis were performed on clinical efficacy, and subgroup analysis along with multiple sensitivity analyses were conducted to verify the robustness of the conclusions. RESULTS A total of 284 children with MUMPP were included in this study, with 142 in the omadacycline group and 142 in the doxycycline group. In terms of efficacy, although the hospitalization time of children in the omadacycline group was longer than that in the doxycycline group ( P <0.05), the lung lesion absorption rate and clinical efficacy were significantly higher or better than those in the doxycycline group ( P <0.05). The results of multivariate Logistic regression analysis showed that medication (OR=5.300, 95%CI: 2.526-11.123), length of hospital stay (OR=1.348, 95%CI: 1.167-1.556), and medication duration (OR=1.422, 95%CI: 1.169-1.729) were influencing factors of clinical efficacy ( P <0.05). The subgroup analysis results showed that the clinical efficacy of omadacycline was significantly better than that of doxycycline in all subgroups ( P <0.05). The results of multiple sensitivity analysis showed that the regression coefficients B of the four models (gradually adjust variables) before and after inverse probability of treatment weighting were significantly greater than 1 ( P <0.05). In terms of safety, there was no statistically significant difference in the inci dence of adverse drug reactions between the two groups of patients ( χ 2 =0.447, P =0.504). CONCLUSIONS In the case of hospitalization and prolonged medication, the efficacy of omadacycline in treating childhood MUMPP is superior to that of doxycycline, and its safety is good.

OBJECTIVE To investigate the prevalence and influencing factors of potentially inappropriate medication (PIM) among the elderly in nursing homes in Urumqi based on three PIM screening tools, and to compare the applicability of different tools. METHODS A cross-sectional study design was adopted. Elderly individuals from six nursing homes in Urumqi were selected as the research subjects from May 2021 to September 2023. Demographic characteristics, disease burden and medication records of the elderly were collected. PIM screening was performed using the Chinese PIM criteria (2024 edition), the American Geriatrics Society (AGS) Beers criteria (2023 edition), and the Screening Tool of Older Person’S Prescriptions(STOPP)/Screening Tool to Alert to Right Treatment(START) (2023 edition). Fleiss’s Kappa test was used to assess the consistency among the three screening tools, and multivariate Logistic regression was used to analyze the influencing factors of PIM. RESULTS The prevalence of PIM screened by the Chinese PIM criteria was 47.4% (323/682), by the AGS Beers criteria was 43.4% (296/682), and by the STOPP criteria was 50.9% (347/682). The consistency among the three screening tools was low (Fleiss’s Kappa=0.12, P <0.001). Multivariate Logistic regression analysis showed that all three screening tools indicated that polypharmacy, aspirin use and psychotropic drug use were independent risk factors for PIM among elderly in nursing houses (all OR>1, P <0.05). CONCLUSIONS The prevalence of PIM among the elderly in nursing homes in Urumqi is relatively high. Polypharmacy, aspirin use and psychotropic drug use are common independent risk factors for PIM. There are differences in screening results among the three tools with low consistency. The Chinese PIM criteria can serve as a first-line tool for PIM screening in nursing homes.

OBJECTIVE To explore the intervention mechanism of Bushen anzhi decoction (BSAZD) in rats with insomnia induced by kidney failing to store spirit. METHODS A total of 36 SD rats were randomly divided into normal group (normal saline), model group (normal saline), eszopiclone group (positive control group, 0.27 mg/kg), and low-, medium- and high-dose BSAZD groups (5.85, 11.70, 23.40 g/kg), with 6 rats in each group. Except for the normal group, rats in the remaining groups were subjected to combined administration of D-galactose and DL-4-chlorophenylalanine to establish the rat model of insomnia due to kidney failing to store spirit. After successful modeling, corresponding liquid medicine or normal saline was intragastrically administered once daily for 14 consecutive days. After the last administration, behavioral indicators and hippocampal histopathological morphology of rats were detected. Untargeted metabolomics was adopted to screen serum differential metabolites and enrich relevant signaling pathways. RESULTS Compared with the model group, the high-dose BSAZD group exhibited significantly increased open arm entries , open arm time and sleep time ( P <0.05), accompanied by markedly decreased closed arm entries, closed arm time and sleep latency ( P <0.05). Hippocampal neurons in the high-dose BSAZD group were arranged regularly, and the size, morphology and location of cell nuclei were nearly normal. Untargeted metabolomics analysis identified oxidized glutathione, glutamate and other differential metabolites in serum of rats in the high-dose BSAZD group; these differential metabolites were mainly enriched in GABAergic synapse, glutamatergic synapse, cAMP signaling pathway and 2-oxocarboxylic acid metabolism pathway. CONCLUSIONS BSAZD can improve sleep quality, relieve anxiety-like behaviors in rats with insomnia due to kidney failing to store spirit. Its therapeutic mechanism may be associated with regulating GABAergic and glutamatergic synaptic pathways to restore neurotransmitter balance and further alleviate oxidative stress injury, modulating the cAMP signaling pathway to facilitate neural repair, and intervening the 2-oxocarboxylic acid metabolism pathway to optimize energy supply.

ObjectiveTo investigate the association of the serum levels of Golgi protein 73 (GP73), hypoxia-inducible factor-1α (HIF-1α), and matrix metalloproteinase-9 (MMP-9) before and after transcatheter arterial chemoembolization (TACE) with the treatment outcome of patients with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). MethodsA total of 135 patients with HBV-related HCC who received TACE for the first time in The First Affiliated Hospital of Xinjiang Medical University from January 2023 to October 2025 were enrolled as subjects, and the serum levels of GP73, HIF-1α, and MMP-9 were measured before TACE and at 1 month after TACE. According to the treatment outcome after TACE, the patients were divided into remission group and non-remission group. The two groups were compared in terms of general information and the serum levels of GP73, HIF-1α, and MMP-9 before and after treatment. The Logistic regression analysis was used to investigate the influencing factors for the efficacy of TACE, and the receiver operating characteristic (ROC) curve was used to assess the value of the serum levels of GP73, HIF-1α, and MMP-9 before treatment used alone or in combination in predicting the efficacy of TACE. The independent-samples t test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. ResultsAmong the 135 patients after treatment, 78 (57.78%) were enrolled in the remission group and 57 (42.22%) were enrolled in the non-remission group. Before treatment, the remission group had significantly lower serum levels of GP73, HIF-1α, and MMP-9 than the non-remission group (all P<0.05); after treatment, both groups had reductions in the serum levels of GP73, HIF-1α, and MMP-9, and the remission group had significantly lower levels than the non-remission group (all P<0.05). The binary Logistic regression analysis showed that increases in the serum levels of GP73, HIF-1α, and MMP-9 before treatment were independent influencing factors for the efficacy of TACE (all P<0.05). The ROC curve analysis showed that the serum levels of GP73, HIF-1α, and MMP-9 before treatment used alone had an area under the ROC curve (AUC) of 0.799, 0.835, and 0.777, respectively, in predicting the efficacy of TACE, among which HIF-1α showed the highest predictive value, and the combination of these three indicators had an AUC of 0.950, a Youden index of 0.787, an optimal cut-off value of 0.39, a sensitivity of 87.72%, and a specificity of 91.03%. ConclusionTACE can reduce the serum levels of GP73, HIF-1α, and MMP-9 in patients with HBV-related HCC, and patients with a good outcome tend to have greater reductions. The high serum levels of GP73, HIF-1α, and MMP-9 before treatment are independent risk factors for poor short-term efficacy of TACE, and the combination of these three indicators has a relatively high value in predicting the efficacy of TACE.

OBJECTIVE To optimize the preparation process of Pollen Typhae dripping pills.METHODS Using appearance morphology, roundness, tailing phenomenon, adhesion condition, friability, and total flavonoids content of Pollen Typhae as evaluation indicators, the analytic hierarchy process-entropy weight method (AHP-EWM) hybrid weighting method was employed to determine the weight coefficients of each indicator and calculate the comprehensive score as the response value. The effects of matrix type and ratio, drug-to-matrix ratio, and condensation temperature on the forming process of dripping pills were respectively investigated, through single-factor experiments and Box-Behnken response surface methodology and the optimal process was optimized and validated. The cumulative dissolution rate of Pollen Typhae dripping pills within 150 min was determined and compared with that of total flavonoid extract from Pollen Typhae .RESULTS The optimal preparation process for Pollen Typhae dripping pills was determined as follows: the ratio of PEG4000 to PEG6000 was 2∶1, the drug-to-matrix ratio was 1∶2, and the condensation temperature was 17.5 ℃. The measured average comprehensive score of dripping pills prepared under these conditions was 9.208 (RSD=0.91%, n =3), with a relative error of 0.83% compared to the predicted value of 9.285. The release mechanism of Pollen Typhae dripping pills was Fickian diffusion controlled deceleration release. The initial dissolution rate was fast, and the dissolution rate decreased in the middle and later stages. The total flavonoid extract from Pollen Typhae was released rapidly in the initial dissolution stage and quickly entered the plateau phase. Their maximum dissolution rates were 95.96% and 84.07%, respectively.CONCLUSIONS The optimized preparation process for Pollen Typhae dripping pills was stable and reliable. The dissolution rate of Pollen Typhae dripping pills prepared by optimized process was higher than that of the total flavonoid extract from Pollen Typhae .

Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

BACKGROUND:
Cervical squamous cell carcinoma (CESC), the most common subtype of cervical cancer, is primarily caused by the high-risk human papillomavirus (HPV) infection and genetic susceptibility. Single-cell RNA sequencing (scRNA-seq) has been widely used in CESC research to uncover the diversity of cell types and states within tumor tissues, enabling a detailed study of the tumor microenvironment (TME). This technology allows precise mapping of HPV infection in cervical tissues, providing valuable insights into the initiation and progression of HPV-mediated malignant transformation.
METHODS:
We performed the scRNA-seq to characterize gene expression in tumor tissues and paired adjacent para-cancerous tissues from four patients with early-stage CESC using the 10× Genomics platform. The HPV infection and its subtypes were identified using the scRNA data and viral sequence mapping, and trajectory analyses were performed using HPV+ or HPV- cells. Interactions between different types of keratinized cells and their interactions with other cell types were identified, and pathways and specificity markers were screened for proliferating keratinized cells. The Cancer Genome Atlas (TCGA) dataset was used to verify the prognostic correlation between tumor-specific PI3+S100A7+ keratinocyte infiltration and CESC, and the localization relationship between PI3+S100A7+ keratinocytes and macrophages was verified by immunofluorescence staining.
RESULTS:
Various types of keratinocytes and fibroblasts were the two cell types with the most significant differences in percentage between the tumor tissue samples and paired adjacent non-cancerous tissue samples in the early stages of CESC. We found that PI3+S100A7+ keratinocytes were associated with early HPV-positive CESC, and PI3+S100A7+ keratinocytes were more abundant in tumors than in adjacent normal tissues in the TCGA-CESC dataset. Analysis of clinical information revealed that the infiltration of PI3+S100A7+ keratinocytes was notably higher in tumors with poor prognosis than in those with good prognosis. Additionally, multiplex immunofluorescence analysis showed a specific increase in PI3+S100A7+ expression within tumor tissues, with PI3+S100A7+ keratinocytes and CD163+ macrophages being spatially very close to each other. In the analysis of cell-cell interactions, macrophages exhibited strong crosstalk with PI3+S100A7+ proliferating keratinocytes in HPV-positive CESC tumors, mediated by tumor necrosis factor (TNF), CCL2, CXCL8, and IL10, highlighting the dynamic and tumor-specific enhancement of macrophage-keratinocyte interactions, which are associated with poor prognosis and immune modulation. Using CIBERSORTx, we discovered that patients with high infiltration of both PI3+S100A7+ proliferating keratinocytes and macrophages had the shortest overall survival. In the analysis of cell-cell interactions, PI3+S100A7+ proliferating keratinocytes and macrophages were found to be involved in highly active pathways that promote differentiation and structure formation, including cytokine receptor interactions, the Nuclear Factor kappa-light-chain-enhancer of activated B cells (NF-κB) signaling pathway, and TNF signaling pathway regulation. Further subtyping of fibroblast populations identified four subtypes. The C1 group, characterized by its predominance in tumor tissues, is a subtype enriched with cancer-associated fibroblasts (CAFs), whereas the C3 group is primarily enriched in adjacent non-cancerous tissues and consists of undifferentiated cells. Moreover, the distinct molecular and cellular differences between HPV16- and HPV66-associated tumors were demonstrated, emphasizing the unique tumor-promoting mechanisms and microenvironmental influences driven by each HPV subtype.
CONCLUSIONS
We discovered a heterogeneous population of keratinocytes between tumor and adjacent non-cancerous tissues caused by HPV infection and identified macrophages and specific CAFs that play a crucial role during the early stage in promoting the inflammatory response and remodeling the cancer-promoting TME. Our findings provide new insights into the transcriptional landscape of early-stage CESC to understand the mechanism of HPV-mediated malignant transformation in cervical cancer.
