Objective To verify the radiation shielding effects of a self-developed protective shield for infant bedside X-ray radiography, and measure the dose distribution in the indoor radiation field with and without the shield, and to provide guidance for the radiation protection of infants sharing the room. Methods A MUX-100J mobile medical diagnostic X-ray machine was used as the radiographic device to simulate the exposure conditions of infant bedside X-ray radiography. The ambient dose equivalent rates at measurement points in eight directions on the irradiation plane in the indoor radiation field were measured with and without the protective shield using an AT1121 X/γ dose rate meter under the conventional condition of 56 kV and the maximum single exposure time. Results During infant bedside X-ray radiography, the dose levels in all directions on the irradiation plane within 150 cm from the scatterer center were essentially symmetrically distributed. The ambient dose equivalent rate at 100 cm from the scatterer center on the irradiation plane was (8.01-8.28)×103 μSv/h without the protective shield and 48-84 μSv/h with the shield. At various distances from the scatterer center in all directions on the irradiation plane, the doses measured with the protective shield ranged from 0.34% to 14.12% of those measured without the shield, with an average of 1.85%. Conclusion The dose levels in the indoor radiation field were significantly reduced with the protective shield during infant bedside X-ray radiography. The use of the protective shield can effectively reduce the radiation risk for individuals near the radiographic site within the same room.

Farrerol is a dihydroflavone compound extracted from the dried leaves of Rhododendron dauricum belonging to the Ericaceae family. This article systematically reviews relevant research on farrerol both domestically and internationally, summarizes its pharmacological activities and mechanisms of action, and finds that it exerts cardiovascular and cerebrovascular protective effects by maintaining the homeostasis of vascular endothelial function and inhibiting vascular intimal hyperplasia; exerts renal protective effects by activating the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway to reduce renal damage; exerts liver protective effects by inhibiting the phosphatidylinositol 3-kinase/protein kinase B signaling pathway, activating the Nrf2 signaling pathway, improving insulin resistance, and reducing lipid deposition in the liver; exerts neuroprotective effects by activating the Nrf2/Keap1 signaling pathway, inhibiting the Toll-like receptor 4 and cyclic GMP-AMP synthase/stimulator of interferon genes signaling pathways to reduce neuroinflammatory damage; exerts bone protective effects by promoting tendon formation and inhibiting osteoclast differentiation; exerts antitumor effects by inducing tumor cell apoptosis and weakening tumor cell invasion and metastasis; and exerts antibacterial effects by downregulating α -toxin expression, interfering with β -lactamase/penicillin-binding protein 2a (PBP2a), and inhibiting PBP2a oligomerization. Currently, research on the pharmacological effects of farrerol is still mainly focused on animal and cell experiments. Further mechanistic studies and clinical trials are needed to provide theoretical basis for its new drug development and clinical application.

OBJECTIVE To investigate the clinical efficacy of integrating pharmacists into family health teams (FHTs) for long-term medication therapeutical management (MTM) in stroke patients, and empirically evaluate the service model. METHODS A pharmacist team, jointly established by clinical and community pharmacists from the Affiliated Suzhou Hospital of Nanjing Medical University (hereinafter referred to as “our hospital”), developed a pharmacist-supported MTM model integrated into FHTs. Using a prospective randomized controlled design, 170 stroke patients discharged from our hospital (July 2022-December 2023) and enrolled in FHTs at Suzhou Runda Community Hospital were randomly divided into trial group (88 cases) and control group (82 cases) according to random number table. The control group received routine FHTs care (without pharmacist involvement in the team collaboration), while the trial group xhz8405@126.com received 12-month MTM services supported by pharmacists via an information platform. These services specifically included innovative interventions such as personalized medication regimen optimization based on the MTM framework, dynamic medication adherence management, medication safety monitoring, a home medication assessment system, and distinctive service offerings. Outcomes of the 2 grousp were compared before and after intervention, involving medication adherence (adherence rate, adherence score), compliance rates for stroke recurrence risk factors [blood pressure, low-density lipoprotein cholesterol (LDL-C)], and incidence of adverse drug reactions (ADR). RESULTS After 12 months, the trial group exhibited significantly higher medication adherence rates, improved adherence scores, higher compliance rates for blood pressure and LDL-C targets compared to the control group (P<0.05). The incidence of ADR in the trial group (4.55%) was significantly lower than that in the control group (8.11%), though the difference was not statistically significant (P> 0.05). CONCLUSIONS Pharmacist involvement in FHTs to deliver MTM services significantly enhances medication adherence and optimizes risk factor for stroke recurrence, offering practical evidence for advancing pharmaceutical care in chronic disease management under the family doctor system.

Monotropein is a compound classified into iridoid which is found in herbaceous plants Morindae officinalis. It possesses anti-inflammatory, antioxidant, and anti-osteoarthritic activities. Previous study indicates that monotropein may have the potential to combat cardiovascular disease, although the related mechanism remains unclear. In this study, we constructed the model of atherosclerosis by oxidized low density lipoprotein-induced vascular smooth muscle cells and LDLR –/–mice given high-fat diet to investigate the effects of monotropein on atherosclerosis.Our results showed that monotropein treatment significantly reduced the area of atherosclerotic plaques and necrotic cores in mice, inhibited the proliferation and migration of vascular smooth muscle cells, and reduced inflammatory responses and oxidative stress, which in turn alleviated atherosclerosis. In addition, we found that monotropein reduced the expression levels of P-NF-κB and P-AP-1. In conclusion, our data suggest that monotropein inhibited the proliferation and migration of vascular smooth muscle cells by mediating the activity of NF-κB, AP-1, reducing the level of inflammation and oxidative stress, and thus resisting the development of atherosclerosis. These findings demonstrate the efficacious therapeutic impact of monotropein on atherosclerosis and elucidate its specific target.

Objective:
To investigate the relationship between relative grip strength and hyperuricemia (HUA) levels in university freshmen, and to explore the potential value of muscle function indicators in HUA prevention among young populations, so as to provide new scientific evidences for HUA control in the demographic.
Methods:
Utilizing health examination data from 1 744 freshmen enrolled in a Shaanxi Province university in September 2024, absolute grip strength was measured using CAMRY electronic dynamometers, with relative grip strength subsequently calculated. Spearman correlation analysis was employed to examine relationships between student characteristics and relative grip strength, and binary Logistic regression models assessed the association strength between relative grip strength and HUA.
Results:
The overall HUA detection rate among freshmen was 29.8%, with significant gender differences (male:43.1%; female:24.0%; χ 2=64.62, P <0.01). Correlation analysis revealed significant associations between relative grip strength, body weight, height, body mass index (BMI) and HUA in both genders (boys: r =-0.27, 0.54, 0.11 , 0.53; girls: r =-0.18, 0.33, 0.08, 0.33, all P <0.05). Binary Logistic regression demonstrated that each standard deviation increase in relative grip strength reduced HUA risk by 77% in males ( OR=0.23, 95%CI =0.14-0.37) and 80% in females ( OR=0.20, 95%CI =0.11-0.36) (both P <0.01).
Conclusions
Relative grip strength represents a significant factor associated with HUA in university students. Incorporating muscle strength training into HUA prevention programs and establishing muscle function based HUA risk warning systems should be considered.
