Objective:
To investigate the efficacy of magnesium-strontium co-doped hydroxyapatite mineralized collagen (MSHA/Col) in improving the bone repair microenvironment and enhancing bone regeneration capacity, providing a strategy to address the insufficient biomimetic composition and limited bioactivity of traditional hydroxyapatite mineralized collagen (HA/Col) scaffolds.
Methods:
A high-molecular-weight polyacrylic acid-stabilized amorphous calcium magnesium strontium phosphate precursor (HPAA/ACMSP) was prepared. Its morphology and elemental distribution were characterized by high-resolution transmission electron microscopy (TEM) and energy-dispersive spectroscopy. Recombinant collagen sponge blocks were immersed in the HPAA/ACMSP mineralization solution. Magnesium-strontium co-doped hydroxyapatite was induced to deposit within collagen fibers (experimental group: MSHA/Col; control group: HA/Col). The morphological characteristics of MSHA/Col were observed using scanning electron microscopy (SEM). Its crystal structure and chemical composition were analyzed by X-ray diffraction and Fourier transform infrared spectroscopy, respectively. The mineral phase content was evaluated by thermogravimetric analysis. The scaffold's porosity, ion release, and in vitro degradation performance were also determined. For cytological experiments, CCK-8 assay, live/dead cell staining, alkaline phosphatase staining, alizarin red S staining, RT-qPCR, and western blotting were used to evaluate the effects of the MSHA/Col scaffold on the proliferation, viability, early osteogenic differentiation activity, late mineralization capacity, and gene and protein expression levels of key osteogenic markers [runt-related transcription factor 2 (Runx2), collagen type Ⅰ (Col-Ⅰ), osteopontin (Opn), and osteocalcin (Ocn)] in mouse embryonic osteoblast precursor cells (MC3T3-E1).
Results:
HPAA/ACMSP appeared as amorphous spherical nanoparticles under TEM, with energy spectrum analysis showing uniform distribution of carbon, oxygen, calcium, phosphorus, magnesium, and strontium elements. SEM results of MSHA/Col indicated successful complete intrafibrillar mineralization. Elemental analysis showed the mass fractions of magnesium and strontium were 0.72% (matching the magnesium content in natural bone) and 2.89%, respectively. X-ray diffraction revealed characteristic peaks of hydroxyapatite crystals (25.86°, 31°-34°). Infrared spectroscopy results showed characteristic absorption peaks for both collagen and hydroxyapatite. Thermogravimetric analysis indicated a mineral phase content of 78.29% in the material. The scaffold porosity was 91.6% ± 1.1%, close to the level of natural bone tissue. Ion release curves demonstrated sustained release behavior for both magnesium and strontium ions. The in vitro degradation rate matched the ingrowth rate of new bone tissue. Cytological experiments showed that MSHA/Col significantly promoted MC3T3-E1 cell proliferation (130% increase in activity at 72 h, P < 0.001). MSHA/Col exhibited excellent efficacy in promoting osteogenic differentiation, significantly upregulating the expression of osteogenesis-related genes and proteins (Runx2, Col-Ⅰ, Opn, Ocn) (P < 0.01).
Conclusion
The MSHA/Col scaffold achieves dual biomimicry of natural bone in both composition and structure, and effectively promotes osteogenic differentiation at the genetic and protein levels, breaking through the functional limitations of pure hydroxyapatite mineralized collagen. This provides a new strategy for the development of functional bone repair materials

ObjectiveThis paper aims to observe the protective effect of Huamoyan granules on knee osteoarthritis (KOA) and explore whether its protective effect is oriented toward an anti-inflammatory direction by regulation of macrophage polarization, which can effectively inhibit the progression of pathological inflammatory response, reduce the release of inflammatory pain mediators, and downregulate the protein expression level of transient receptor potential vanilloid 1 (TRPV1), so as to provide experimental evidence for its clinical application and investigate its action mechanism. MethodsAfter adaptive feeding, Sprague-Dawley (SD) rats were randomly divided into six groups: sham group, model group, celecoxib group, and high, medium, and low-dose synovitis granule groups (9.6, 4.8, 2.4 g·kg-1). The administration dose of celecoxib capsules was 20 mg·kg-1. There were 10 rats in the sham group and 12 rats in the model group and each administration group. A KOA animal model was established by means of intra-articular injection of sodium iodoacetate into the knee joint. From the 10th day of the experiment, each administration group was given intragastric administration at a dose of 10 mL·kg-1 for 4 weeks. General conditions of rats in each group were assessed daily. The pressure pain threshold (PPT) to mechanical stimulation and joint diameter were recorded. X-ray examination was performed on the right knee joints of rats for imaging analysis. Enzyme linked immunosorbent assay (ELISA) was performed to detect the tumor necrosis factor-α (TNF-α), serum interleukin-1β (IL-1β), and other pro-inflammatory cytokines in rat serum samples, as well as the expression levels of neurogenic inflammatory mediators such as nerve growth factor (NGF) and calcitonin gene-related peptide (CGRP). Histopathological changes in the knee joint synovial tissues were examined by hematoxylineosin (HE) staining. Safranin O-fast green staining was performed to observe and evaluate the degree of knee cartilage lesions. Western blot was employed to quantitatively analyze TRPV1, p38 mitogen-activated protein kinase (p38 MAPK), and phosphorylated (p)-p38 MAPK in rat knee synovial tissues. Immunofluorescence (IF) was used to measure and assess M1/M2 macrophage polarization. ResultsCompared with those in the sham group, the circumference and joint diameter of the right knee were markedly enlarged in the model group (P<0.01), while PPTs of rats showed a significant reduction (P<0.01). The contents of IL-1β, TNF-α, CGRP, and NGF in rats' serum were significantly elevated (P<0.01), and the synovial Krenn score was increased (P<0.01). The Mankin score of cartilage tissue was increased (P<0.01), and the protein expressions of TRPV1 and p-p38 MAPK/p38 MAPK were significantly upregulated (P<0.01). The experimental intervention significantly reduced the proportion of pro-inflammatory M1 macrophages in the total macrophage population (P<0.01), and the percentage of M2 macrophages was decreased (P<0.01). The M1/M2 macrophage ratio was significantly elevated (P<0.01). Knee joint diameters of all dose groups of Huamoyan granules and the celecoxib group were reduced (P<0.01) compared with those of the model group, and the PPT recovery speeds in the high and medium-dose groups of Huamoyan granules were more obvious (P<0.05). The contents of IL-1β, CGRP, and NGF in the rats' serum in all administration groups were significantly reduced (P<0.05, P<0.01), and the content of TNF-α in rats' serum was significantly reduced (P<0.01). All dose groups of Huamoyan granules demonstrated significant reductions in both synovial Krenn score (P<0.05, P<0.01) and protein expression of TRPV1 and p-p38 MAPK/p38 MAPK in rats' synovial tissues (P<0.01). The percentage of M1 macrophages in the synovial tissues of the celecoxib group and all dose groups of Huamoyan granules was decreased (P<0.01). The percentage of M2 macrophages was increased (P<0.05), and the M1/M2 ratio was decreased (P<0.01). ConclusionHuamoyan granules can alleviate the inflammatory response of KOA, reduce the release of inflammatory pain mediators, and downregulate TRPV1 protein expression by regulating macrophage polarization. Its mechanism may be related to the TRPV1/p38 MAPK signaling pathway, thereby achieving the effect of improving peripheral pain hypersensitivity in KOA.

ObjectiveTo observe the clinical efficacy and safety of Yuyin Lidan granules (YYLD) in preventing the recurrence of common bile duct stones (CBDS) in patients with liver and gallbladder dampness-heat syndrome following endoscopic retrograde cholangiopancreatography (ERCP). MethodsThis randomized, parallel, controlled trial enrolled postoperative CBDS-ERCP patients who met the inclusion and exclusion criteria. Sixty-four patients were randomly assigned to an observation group or a control group, with 32 cases in each. Both groups received conventional Western medical treatment after ERCP, while the observation group additionally received YYLD for 8 weeks. The follow-up period lasted for 1 year. The efficacy indicators included bile bilirubin levels, traditional Chinese medicine (TCM) syndrome scores, clinical efficacy rate, pancreatitis and inflammation markers, postoperative liver function, and CBDS recurrence rate at 1-year follow-up, which were used to jointly evaluate the clinical efficacy and safety of both groups. ResultsA total of 56 patients completed the study and were included in the final analysis, i.e., 29 in the observation group and 27 in the control group. Baseline characteristics were comparable between the two groups. Compared with pre-treatment and with the control group after treatment, the bile bilirubin level in the observation group significantly decreased (P<0.05). After treatment, the clinical cure and marked improvement rates were higher in the observation group than in the control group, showing a statistically significant difference in overall clinical efficacy (P<0.05). Compared with pre-treatment, the primary and secondary symptoms in the observation group, as well as the primary symptom and the secondary symptom of nausea and vomiting in the control group (weeks 4 and 8), were significantly reduced (P<0.05). Compared with the control group after treatment, the observation group showed significant reductions in the primary symptom of loose stools/constipation (day 5 and week 4) and in three secondary symptoms, i.e., bitter taste and sticky dry mouth, abdominal distension and poor appetite (throughout the treatment period), and general heaviness and fatigue (day 5 and week 4), with statistical differences (P<0.05). Compared with pre-treatment, both groups showed decreased lipase and urinary amylase levels (P<0.05). However, no significant between-group differences were observed in pancreatitis or inflammation-related indices after treatment. Compared with pre-treatment, all liver function indicators in the observation group and alanine aminotransferase ( ALT ), γ-glutamyl transferase ( γ-GT ), alkaline phosphatase (ALP), and conjugated bilirubin in the control group significantly decreased at weeks 4 and 8 (P<0.05). Compared with the control group after treatment, only serum total bilirubin and unconjugated bilirubin were significantly reduced in the observation group during the treatment period (P<0.05). ConclusionYYLD combined with conventional Western medical treatment can effectively regulate bilirubin metabolism (in bile and serum), improve TCM clinical symptoms, and prevent CBDS recurrence after ERCP in patients with liver and gallbladder dampness-heat syndrome. This regimen is safe and effective and is worthy of further clinical research and promotion.

AIM: To compare the clinical efficacy of goniosynechialysis versus trabeculectomy combined with cataract phacoemulsification in treating glaucoma complicated with cataract.METHODS:From January 2019 to January 2024, patients with glaucoma complicated with cataract diagnosed in our hospital were included as the study subjects. They were assigned into trabeculectomy group and goniosynechialysis group based on different surgical methods. The trabeculectomy group was treated with cataract phacoemulsification combined with trabeculectomy, while the goniosynechialysis group was treated with cataract phacoemulsification combined with goniosynechialysis. The improvement of visual acuity, anterior chamber depth, chamber angle width, intraocular pressure, whole en face vessel density within the optic disc head and in the peripapillary region, and complications were compared between two groups.RESULTS: A total of 120 patients(120 eyes)with glaucoma combined with cataract were included in this study, among which 60 eyes were in the trabeculectomy group and 60 eyes in the goniosynechialysis group. The age of the trabeculectomy group was 60.72±6.16 years, including 28 males and 32 females. The age of the goniosynechialysis group was 61.04±6.24 years, including 31 males and 29 females. At 3 mo after surgery, the visual acuity of patients in both groups improved significantly, and the improvement of visual acuity in the goniosynechialysis group was significantly better than that in the trabeculectomy group(all P<0.01). At 3 mo after surgery, the anterior chamber depth and chamber angle width of patients in both groups were higher than those before surgery, and with the goniosynechialysis group being higher than the trabeculectomy group(all P<0.01), while the intraocular pressure was lower than that before surgery, and with the goniosynechialysis group being lower than the trabeculectomy group(all P<0.01). Before surgery, there was no significant difference in the whole en face vessel density within the optic disc head between the two groups(P>0.05), however, the whole en face vessel density within the optic disc head in both groups on 1 d after surgery were significantly lower than before surgery(all P<0.05); and compared with 1 d after surgery, there was a significant increase at 1 wk, 1, and 3 mo after surgery(all P<0.05); the whole en face vessel density within the optic disc head in the goniosynechialysis group was significantly higher than that in the trabeculectomy group at various time points after surgery(all P<0.05). However, there was no significant difference in the whole en face vessel density in the peripapillary region between the two groups before surgery and various time points after surgery(all P>0.05). Within 3 mo after surgery, the incidence of complications in the goniosynechialysis group(8.3%)was significantly lower than that in the trabeculectomy group(21.7%; P<0.05).CONCLUSION:Goniosynechialysis combined with phacoemulsification is more effective than trabeculectomy combined with phacoemulsification in the treatment of patients with glaucoma complicated with cataract in improving the visual acuity and whole en face vessel density within the optic disc head of patients, increasing the anterior chamber depth and chamber angle width, reducing intraocular pressure and the risk of complications. It has high safety and ideal short-term efficacy.

Objective To analyze the epidemiological characteristics and disease burden of liver cancer in Guangdong Province in 2020, and to provide a scientific foundation for the development of regionalized prevention and control strategies for liver cancer. Methods According to the cancer registry data of Guangdong Province, the incidence, mortality and age-standardized rate by Chinese standard population in 2020 were calculated to analyze the epidemiological characteristics of liver cancer. The disability adjusted life years (DALYs), year of life loss (YLL), year of lived with disability (YLD), and cause-eliminated life expectancy were used to assess the disease burden of liver cancer. Results In 2020, the crude incidence rate and the age-standardized incidence rate of liver cancer in Guangdong Province were 27.79/100 000 and 20.84/100 000,respectively, and the crude mortality rate and the age-standardized mortality rate of liver cancer were 25.49/100,000 and 17.64/100 000, respectively. The total DALY and DALY rate of liver cancer in Guangdong Province were 515 311 person-years and 513.83/100 000, respectively. After eliminating the causes of death from liver cancer, the life expectancy in Guangdong Province increased from 84.60 years to 84.99 years. All indicators consistently demonstrated that the burden of liver cancer was higher in males than that in females, and the burden of liver cancer was higher in rural areas than that in urban areas. Conclusion Liver cancer in Guangdong Province exhibits a high incidence, mortality and disease burden level in 2020. There are obvious differences of gender, age and region in cancer burden. It is necessary to strengthen liver cancer screening and diagnosis and treatment in men, the elderly and those in rural areas to reduce the burden of liver cancer gradually in Guangdong Province.

Objective: Blood safety surveillance is a critical measure for the objective assessment of blood quality and enhancing transfusion safety. This study aims to comprehensively understand the current status of blood safety surveillance and management in blood collection and supply institutions in Sichuan Province, systematically analyze existing problems and vulnerabilities, and provide a basis for optimizing management strategies and improving capabilities to ensure blood safety. Methods: The Blood Safety Surveillance questionnaire was designed, covering adverse donor reaction reporting, management of adverse events, and transfusion adverse reaction feedback. An online survey was conducted via Questionnaire Star platform among 21 blood collection and supply institutions in the province, gathering information on management systems, process implementation, and utilization of monitoring data. The collected data were organized and statistically analyzed using Excel. Results: The questionnaire response rate and validity rate were both 100%. Blood collection and supply institutions in Sichuan Province have generally established a blood safety surveillance system and achieved positive outcomes. Regarding adverse events in blood collection and supply, 95.24% (20 institutions) have established reporting procedures, and 66.67% (14) collect information through multiple channels such as internal reports, external reports, and statistical trend feedback. A total of 90.48% (19) institutions regularly summarize and analyze adverse event data, and 85.71% (18) produce reports with improvement recommendations based on this analysis.71.43% (15) institutions implement reward and penalty measures, and 71.43% (15) report underreporting or omission due to accountability or performance concerns. In terms of monitoring adverse blood donation reactions, all blood collection and supply institutions have established full-process management systems.76.19% (16) collect data through multiple approaches, including on-site donation records, voluntary donor reports, and donor follow-ups. Adverse reactions were followed up in 95.24% (20) of institutions with 65% (13) completing follow-ups within 24 hours.80.95% (17) have established investigation procedures, while 66.67% (14) believe underreporting or omission still occurs. All blood collection and supply institutions regularly compile statistics on adverse donation reactions. Of these, 85.71% (18) institutions providing feedback to management departments and 90.48% (19) analyzing the data and making recommendations.76.19% (16) institutions use monitoring data for return donor management and targeted care, and 71.43% (15 stations) incorporate it into management reviews. Regarding adverse transfusion reactions, 95.24% (20) institutions have established and implemented procedures for isolating, recalling, and tracing of problematic blood units. However, only 42.86% (9) have established feedback mechanisms of adverse transfusion reaction with hospitals, and only 19.05% (4) support direct reporting via information systems.47.62% (10) institutions regularly analyze adverse transfusion reaction data, and 19.05% (4) provide feedback and recommendations to relevant hospitals. All blood collection and supply institutions reported challenges in collecting hospital feedback, citing complexities in data collection and reporting processes. Conclusion: Blood safety surveillance systems have been preliminarily established in Sichuan Province. However, further strengthening is still required, including conducting in-depth data analysis and utilization, standardizing the configuration of emergency medications and equipment, and improving feedback mechanisms for adverse transfusion reactions. To improve the overall level of blood safety management, it is recommended to strengthen closed-loop data management, improve feedback mechanisms between blood collection and supply institutions and hospitals, foster a non-punitive reporting culture, and systematically advance the regionalization and standardization of the monitoring system. These efforts will contribute to sustainably improving the overall effectiveness and sustainability of blood safety management.

Ulcerative colitis is a chronic relapsing inflammatory bowel disease. Modern research indicates that immune dysregulation resulting from disruptions in circadian rhythm is closely associated with its pathogenesis. Both Western chronomedicine and traditional Chinese medicine(TCM)" treatment based on temporal factors" emphasize the temporal relationship between natural rhythms and human physiology and pathology. The " midnight-noon and ebb-flow " theory represents the concrete application and deepening of TCM " treatment based on temporal factors" within the realm of chronomedicine. This article correlates the onset time of ulcerative colitis with specific periods in the " midnight-noon and ebb-flow"theory:the Mao period(05:00-07:00),when the yangming large intestine meridian of hand is dominant; the Si period(09:00-11:00),when the taiyin spleen meridian of foot is dominant; and the You period(17:00-19:00),when the shaoyin kidney meridian of foot is dominant. According to this perspective,if the disease manifests during the Mao period,the pathogenesis is attributed to dampnessheat accumulation and disorder of qi and blood. Treatment should focus on clearing heat,resolving dampness,and harmonizing qi and blood,using modified formulas such as Shaoyao Decoction or Baitouweng Decoction. If it occurs during the Si period,the pathogenesis involves spleen deficiency with dampness obstruction and disharmony of qi and blood. Treatment should focus on strengthening the spleen,eliminating dampness,and restoring qi and blood,using modified formulas such as Huangya Decoction or Shenling Baizhu Powder. If it presents during the You period,the pathogenesis is characterized by fire failing to warm earth,and consumption resulting in qi and blood leakage. Treatment should focus on warming the kidney and spleen,and securing qi and blood,using modified formulas such as Sishen Pill or Tianhun Decoction. In addition to oral administration of Chinese herbal medicine,comprehensive therapies including acupuncture,herbal enemas,and acupoint application can provide novel insights for the clinical diagnosis and treatment of ulcerative colitis.

Background Work alienation is a subjectively negative psychological state characterized by detachment from one's job and its environment. Due to heavy workloads, high-intensity tasks, low compensation, as well as pressures related to promotion, nurses are particularly susceptible to work alienation. Objective To meta-analyze the primary factors affecting work alienation of nurses in China, providing an evidence-based foundation for improving nursing management and nurses' physical and mental health. Methods A systematic search was conducted across multiple databases, including PubMed, Embase, the Cochrane Library, Web of Science, CNKI, VIP, Wanfang Data, and DBM, for cross-sectional studies on work alienation and its influencing factors among nurses in China published from inception to December 2024. Two researchers independently conducted literature screening, data extraction, and risk of bias assessment for the included studies. Meta-analysis was performed using Stata 15.0 and RevMan 5.4 software. Pooled effect sizes were calculated using either fixed-effects or random-effects models based on the magnitude of heterogeneity. Results A total of 27 studies involving 13 028 nurses were included in the meta-analysis, from which 11 influencing factors of work alienation were identified. The pooled score for work alienation among nurses in China was 34.79 (95%CI: 32.56, 37.01). Subgroup analysis revealed that the emergency department reported the highest score (36.81, 95%CI: 31.64, 41.98), followed by the intensive care unit (34.99, 95%CI: 32.27, 37.72) and internal medicine department (33.90, 95%CI: 29.10, 38.71). Significant factors influencing work alienation included length of work experience [standardized mean difference (SMD)=0.32, 95%CI: 0.02, 0.61], professional title (SMD=0.30, 95%CI: 0.16, 0.44), monthly income (SMD=0.38, 95%CI: 0.14, 0.62), psychological capital (SMD=–0.41, 95%CI:–0.52, –0.29), work stress (SMD=0.54, 95%CI: 0.49, 0.58), attitude toward aggression and violence management (SMD=–0.38, 95%CI:–0.44, –0.32), and organizational climate (SMD=–0.47, 95%CI: –0.57, –0.36) (P <0.05). Sensitivity analysis confirmed the robustness of the meta-analysis results, and no significant publication bias was detected. Conclusion Nurses in China exhibit a high level of work alienation, particularly in high-acuity settings like emergency and intensive care unit departments compared to general departments. Shorter work experience (<5 years), lower professional title, lower monthly income (<5 000 CNY), and greater work stress are positively correlated with work alienation. In contrast, psychological capital, proactive attitudes toward managing aggression and violence, and a supportive organizational climate are negatively correlated. These findings indicate a need for nursing managers to develop targeted strategies based on these multifaceted factors to mitigate alienation among nursing staff.

This article examines a comprehensive model for managing refractive errors, with a specific focus on myopia. It investigates the epidemiological context of refractive errors and their socio-economic implications. It underscores the importance of early detection and management, especially for severe ocular conditions like retinal lesions and glaucoma. The article critiques existing refractive error management models' limitations and highlights challenges in managing asymptomatic myopic patients. It proposes a “Myopia Chronic Disease Management(MCDM)” model as an innovative comprehensive management approach. The model establishes a data-driven closed-loop management pathway that encompasses screening, diagnosis, intervention, follow-up, and feedback. Through a comparative analysis with the chronic care model(CCM)and the World Health Organization's(WHO)Integrated Patient-Centered Eye Care(IPCEC), it highlights its innovative strengths in integrating digital technologies with multi-tiered healthcare networks. This model encompasses the entire refractive correction process and incorporates strategies for public education via the internet and new media. In terms of strategy implementation, the article discusses the necessity of establishing eye health records and long-term follow-up plans, as well as the potential applications of medical consortium models and family contract-based services in management. Moreover, the article emphasizes the importance of intelligent software systems in chronic ocular condition health management. It provides an overview of the benefits and challenges associated with this novel management model and proposes directions for future research and potential enhancements. Through this thorough examination and analysis, the article highlights the critical importance and effectiveness of implementing comprehensive, multifaceted, and sustained strategies in the management of refractive errors.
