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.

ObjectiveTo investigate the clinical efficacy and potential mechanism of Shengmai Jiuxin decoction in the treatment of acute decompensated heart failure (ADHF) with the traditional Chinese medicine (TCM) pattern of Qi and Yin deficiency, Yang deficiency, and blood stasis. MethodsA total of 68 patients diagnosed with ADHF of Qi and Yin deficiency, Yang deficiency, and blood stasis type were randomly assigned to an observation group (34 cases) and a control group (34 cases). Both groups received conventional Western medical treatment, while the observation group was additionally administered Shengmai Jiuxin decoction. Parameters compared before and after treatment included: TCM syndrome score, TCM syndrome efficacy, New York Heart Association (NYHA) functional classification, left ventricular ejection fraction (LVEF), N-terminal pro-B-type natriuretic peptide (NT-proBNP), six-minute walk distance (6MWD), hypoxia-inducible factor-1 alpha (HIF-1α), vascular endothelial growth factor A (VEGF-A), Caspase-3, and the number of rehospitalizations for heart failure within one month after discharge. ResultsThere were no significant differences in sex, age, vital signs, or underlying diseases between the two groups. Compared with baseline, both groups exhibited significant reductions in TCM syndrome scores, NT-proBNP, and HIF-1α levels (P<0.01), as well as significant increases in 6MWD, LVEF, VEGF-A, and Caspase-3 levels (P<0.05, P<0.01). After treatment, the observation group showed significantly greater reductions in TCM syndrome score, NT-proBNP, HIF-1α, and Caspase-3 levels compared with the control group (P<0.05) and significantly greater increases in 6MWD, TCM syndrome efficacy, and VEGF-A levels (P<0.05). No significant differences were observed between the groups in NYHA functional classification, LVEF, or the number of rehospitalizations for heart failure within one month after discharge. No drug-related adverse events were reported in either group during the treatment period. ConclusionShengmai Jiuxin decoction can improve cardiac function and clinical symptoms in patients with ADHF of Qi and Yin deficiency, Yang deficiency, and blood stasis type. Its mechanisms may be related to the regulation of the HIF-1 signaling pathway by modulating targets such as HIF-1α, VEGF-A, and Caspase-3.

The traditional Chinese medicine(TCM) industry is a crucial part of China's pharmaceutical sector and plays a strategic role in ensuring public health and promoting economic and social development. In response to the practical demand for high-quality development of the TCM industry, this paper focused on the bottlenecks encountered during the digital and intelligent transformation of TCM production systems. Specifically, it explored technical strategies and methodologies for constructing the best TCM production mode. An innovative artificial intelligence(AI)-centered technical architecture for TCM production was proposed, focusing on key aspects of production management including process modeling, state evaluation, and decision optimization. Furthermore, a series of critical technologies were developed to realize the best TCM production mode. Finally, a novel AI-driven TCM production mode characterized by a closed-loop system of "measurement-modeling-decision-execution" was presented through engineering case studies. This study is expected to provide a technological pathway for developing new quality productive forces within the TCM industry.

Pelvic organ prolapse (POP), whose etiology is influenced by genetic and clinical risk factors, considerably impacts women's quality of life. However, the genetic underpinnings in non-European populations and comprehensive risk models integrating genetic and clinical factors remain underexplored. This study constructed the first polygenic risk score (PRS) for POP in the Chinese population by utilizing 20 disease-associated variants from the largest existing genome-wide association study. We analyzed a discovery cohort of 576 cases and 623 controls and a validation cohort of 264 cases and 200 controls. Results showed that the case group exhibited a significantly higher PRS than the control group. Moreover, the odds ratio of the top 10% risk group was 2.6 times higher than that of the bottom 10%. A high PRS was significantly correlated with POP occurrence in women older than 50 years old and in those with one or no childbirths. As far as we know, the integrated prediction model, which combined PRS and clinical risk factors, demonstrated better predictive accuracy than other existing PRS models. This combined risk assessment model serves as a robust tool for POP risk prediction and stratification, thereby offering insights into individualized preventive measures and treatment strategies in future clinical practice.

Objective:To explore the correlations of brain network functional connectivity (FC) alterations with cerebrospinal fluid (CSF) pathological biomarkers in patients with Alzheimer's disease (AD).Methods:A total of 39 patients with cognitive impairment, admitted to Department of Neurology, Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University from January 2020 to December 2022 were recruited; 23 patients were with AD and 16 with non-AD. Clinical data were compared between the 2 groups. Resting-state functional MRI (rs-fMRI) data were collected, and FC differences between brain networks and FC differences within brain networks were compared by independent component analysis. Correlations of FC differences between brain networks and FC differences within brain networks with concentrations of β-amyloid protein 1-42 (Aβ 1-42) and Tau protein in CSF were analyzed. Results:Compared with the non-AD group, AD group had significantly lower Aβ 1-42 in CSF ( P<0.05). Compared with those in the non-AD group, FC alterations between the left frontoparietal network (lFPN) and anterior default mode network (aDMN) and between the visual network (VN) and posterior cingulate cortex (PCC), as well as FC alterations in lFPN, were significantly increased in AD group ( P<0.05). Compared with those in the non-AD group, FC alterations between lFPN and cerebellar network (CEN), and FC alterations in aDMN, sensorimotor network (SMN) and VN were significantly decreased in AD group ( P<0.05). In AD group, FC in SMN was positively correlated with total Tau and phosphorylated-Tau181 in CSF ( P<0.05); FC between VN and PCC was positively correlated with total Tau in CSF ( P<0.05). CSF Aβ 1-42 was positively correlated with FC alterations in aDMN and VN, but negatively correlated with FC in FPN ( P<0.05). Conclusion:In AD patients, characteristic changes in FC within and between multiple brain networks are noted, which are related to changes of Tau protein and Aβ 1-42 in CSF.

Objective:To explore the mediating role of positive coping style between social support and post-discharge coping difficulty among mothers of premature infants, so as to provide guidance for medical staff to deeply understand and improve the post-discharge coping difficulty of mothers.Methods:A convenience sampling method was employed to select 310 mothers of premature infants from the neonatal intensive care units of five tertiary level A hospitals in Shandong Province from March to June 2023 as the study population. A cross-sectional survey was conducted using the general information questionnaire, the Social Support Rating Scale, the Simple Coping Style Questionnaire, and the Post-Discharge Coping Difficulty Scale-Parent Form.Results:A total of 280 valid questionnaires were returned, among which the age of mothers was (32.70 ± 5.08) years. The score of social support, positive coping style and post-discharge coping difficulty in mothers of preterm infants was (42.59 ± 7.40), (23.06 ± 6.75) and (3.64 ± 1.74) points respectively. Social support was positively associated with positive coping style ( r=0.404, P<0.01), social support and positive coping style were negatively associated with post-discharge coping difficulty ( r=-0.368, -0.369, both P<0.01). Positive coping style partially mediated the relationship between social support and post-discharge coping difficulty, which accounted for 31.11% of the total effect. Conclusions:Social support can affect post-discharge coping difficulty of mothers of premature infants through positive coping style. Medical staff should pay attention to the enhancement of social support and the cultivation of positive coping style of mothers of premature infants, and take targeted measures to reduce the post-discharge coping difficulty.

ObjectiveTo evaluate the effectiveness and safety of Qiaoqi Formula (翘芪组方) for mild influenza. MethodsA randomized controlled study was designed, recruiting 74 patients with mild influenza, who were randomly divided into trial group and control group. The trial group took Qiaoqi Formula orally, 40ml each time, twice a day; the control group took Lianhua Qingwen Capsules (连花清瘟胶囊) orally, 1.4 g each time, three times a day. Both groups were treated for 3 consecutive days and follow-up for 4 consecutive days after treatment. The time for fever reduction including onset of fever reduction, complete fever reduction time, fever reduction rates at 24, 48 and 72 hours, improvement of influenza symptoms, total traditional Chinese medicine (TCM) symptom score, and safety indicators in two groups after treatment were recorded. ResultsSixty-five patients were ultimately included, including 36 in the trial group and 29 in the control group. Onset time of fever reduction in the trial group was (15.49±23.47) h, the complete fever reduction time (21.37±30.06)h, and the 24 h, 48 h, 72 h, fever reduction rate was 77.14%, 88.57%, 91.42% respectively. The above indicators of the control group showed as (17.58±20.38)h, (24.30±21.87)h, 61.29%, 90.32%, 96.77% respectively, with no statistically significant differences (P>0.05). On the 7th day after treatment, the total score of TCM syndromes in trial group and control group decreased compared to those before treatment (P<0.05). There was no statistically significant difference in the cure rate, significant effective rate, effective rate, and total effective rate of TCM syndromes between groups (P>0.05). On the 4th day, the lymphocyte ratio of patients in the control group was higher than before treatment, while alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea, and creatinine of both groups before and after treatment were within the normal range. The main adverse reactions in both groups were mild headache and dizziness, and no serious adverse reactions observed. ConclusionThe therapeutic effect of Qiaoqi Formula in treating mild influenza is equivalent to Lianhua Qingwen Capsules, which can shorten the fever reduction time, improve clinical symptoms, and no adverse events observed during the study.
