Objective To explore the difference of efficacy and safety between denosumab and zoledronic acid in the treatment of patients with postmenopausal osteoporosis (PMOP), and to optimize the medication regimen for PMOP patients. Methods A total of 123 PMOP patients with high risk of fracture at the Second Affiliated Hospital of Naval Medical University from September 2021 to March 2024 were selected and randomly divided into two groups: the denosumab group (n=63) and the zoledronic acid group (n=60). Both groups underwent one-year treatment and follow-up, bone metabolism indexes, lumbar vertebrae, femoral neck, and total hip bone mineral density (BMD) were monitored, and any adverse reactions were documented. Results After treatment, the lumbar vertebrae and total hip BMD of patients in the denosumab group and the zoledronic acid group were significantly improved (P<0.05); the femoral neck BMD of patients in the zoledronic acid group was also significantly improved (P<0.05). The improvement of lumbar vertebrae BMD in the denosumab group was significantly better than that in the zoledronic acid group, while the improvement of femoral neck and total hip BMD in the zoledronic acid group was significantly better than that in the denosumab group (P<0.05). Bone metabolism indicators were significantly improved in both groups (P<0.05), and no significant liver and kidney dysfunction were observed. A total of 7 patients in the zoledronic acid group had mild adverse reactions and 5 patients in the denosumab group had mild adverse reactions. Conclusions Denosumab significantly increased lumbar vertebrae BMD and improved bone metabolism markers in PMOP patients, thus reducing risk of fracture and demonstrating good safety.

ObjectiveTo investigate the association of menopausal time and menopausal age with the risk of nonalcoholic fatty liver disease (NAFLD), and to provide a basis for the early prevention and treatment of NAFLD in clinical practice. MethodsRelated data were collected from 373 postmenopausal women who attended the outpatient service of Department of Spleen, Stomach, Liver and Gallbladder Diseases, The First Affiliated Hospital of Henan University of Chinese Medicine, from January 2017 to December 2021, including general information, menopausal age, menopausal time, and presence or absence of NAFLD. The chi-square test was used for comparison of categorical data; the independent-samples t test was used for comparison of normally distributed continuous data between groups, and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between groups. A Logistic regression analysis was used to calculate the association intensity and 95% confidence interval (95%CI) of menopausal time and menopausal age for the risk of NAFLD, and the restricted cubic spline (RCS) method was used to investigate the dose-response relationship between menopausal time/age and the risk of NAFLD. ResultsCompared with the women with normal menopause or late menopause, the women with early menopause had a higher prevalence rate of NAFLD and a higher degree of steatosis and fibrosis (all P<0.05). After adjustment for the confounding factors such as age and age of menarche, the risk of NAFLD in women with a menopausal time of >3 years was 4.80 (95%CI: 1.93 — 11.95, P=0.001) times that in women with a menopausal time of ≤3 years, and the risk of NAFLD in women with early or late menopause was 8.14 times (95%CI: 1.77 — 37.58, P=0.007) and 0.09 times (95%CI: 0.03 — 0.32, P<0.001), respectively, that in those with a normal menopausal age. There is a dose-response relationship between menopausal time/age and the risk of NAFLD. Menopausal time is positively correlated with the association intensity of NAFLD, while menopausal age is negatively correlated with the association intensity of NAFLD. ConclusionThe longer the menopause time and the earlier the menopause age, the ligher the risk of NAFLD.

[Objective] To analyze the loss rate of platelet donors and evaluate the strategies for establishing a platelet donor bank. [Methods] A total of 1 443 donors who joined the HLA and HPA gene donor bank for platelets in Henan Province from 2018 to 2020 were included in this study. Data on the total number of apheresis platelet donations, annual donation frequency, age at enrollment, donation habits (including the number of platelets donated per session and whether they had previously donated whole blood), and enrollment location were collected from the platelet donor information management system. Donor loss was determined based on the date of their last donation. The loss rates of different groups under various conditions were compared to assess the enrollment strategies. [Results] By the time the platelet bank was officially operational in 2022, 421 donors had been lost, resulting in an loss rate of 29% (421/1 443). By the end of 2023, the overall cumulative loss rate reached 52% (746/1 443). The loss rate was lower than the overall level in groups meeting any of the following conditions: total apheresis platelet donations exceeding 50, annual donation frequency of 10 or more, age at enrollment of 40 years or older, donation of more than a single therapeutic dose per session, or a history of whole blood donation two or more times. Additionally, loss rates varied across different enrollment locations, with higher enrollment numbers generally associated with higher loss rates. [Conclusion] Through a comprehensive analysis of donor loss, our center has adjusted its strategies for establishing the donor pool. These findings also provide valuable insights for other blood collection and supply institutions in building platelet donor banks.

ObjectiveTo study the pharmacological substances and mechanisms through which sesquiterpene ZH-13 from Aquilariae Lignum Resinatum improves neuroinflammation. MethodsBV-2 microglial cells were stimulated with lipopolysaccharide (LPS) to induce neuroinflammation. The cells were divided into the normal group, the model group, and the ZH-13 low- and high-dose treatment groups (10, 20 μmol·L-1). The model group was treated with 1 μmol·L-1 LPS. Cell viability was assessed using the cell proliferation and activity assay (CCK-8 kit). Nitric oxide (NO) release in the cell supernatant was measured using a nitric oxide kit (Griess method). The mRNA expression levels of interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), inducible nitric oxide synthase (iNOS), and interleukin-6 (IL-6) were detected by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). The phosphorylation of mitogen-activated protein kinase (MAPK) pathway proteins was assessed by Western blot. ResultsCompared with the model group, ZH-13 dose-dependently reduced NO release from BV-2 cells under LPS stimulation (P<0.05, P<0.01). In the 20 μmol·L-1 ZH-13 treatment group, the mRNA expression levels of IL-1β, TNF-α, iNOS, and IL-6 were significantly reduced compared to the model group (P<0.05, P<0.01). In both the low- and high-dose ZH-13 groups, the expression of the inflammatory factor TNF-α and the phosphorylation of c-Jun N-terminal kinase (JNK) in the upstream MAPK pathway were significantly reduced (P<0.05). After stimulation with the JNK agonist anisomycin (Ani), both low- and high-dose ZH-13 treatment groups showed reduced phosphorylation of JNK proteins compared to the Ani-treated group (P<0.01). ConclusionThe sesquiterpene compound ZH-13 from Aquilariae Lignum Resinatum significantly ameliorates LPS-induced neuroinflammatory responses in BV-2 cells by inhibiting excessive JNK phosphorylation and reducing TNF-α expression. These findings elucidate the pharmacological substances and mechanisms underlying the sedative and calming effects of Aquilariae Lignum Resinatum.

OBJECTIVE To compare the long-term cost-effectiveness of gonadotrophin-releasing hormone analogue (GnRHa) combined with recombinant human growth hormone (rhGH) (combination therapy regimen) versus GnRHa monotherapy (monotherapy regimen) in the treatment of central precocious puberty (CPP). METHODS From the societal perspective and based on a real-world study conducted at West China Second Hospital of Sichuan University, the cost-effectiveness analysis was performed to compare the long-term cost-effectiveness of two pharmacotherapy regimens for CPP girls, with final height as outcome indexes, using per capita disposable income of rural residents and urban residents (20 133-49 283 yuan) in 2022 as the social willing-to-pay (WTP) threshold. The robustness of the basic analysis result was verified by using one-way sensitivity analysis and probability sensitivity analysis, and the cost-effectiveness of different combinations of long-acting preparations was compared using scenario analysis. RESULTS The basic analysis result showed that the combination therapy regimen required an additional cost of 25 193.49 yuan for every one-centimeter improvement in the final height of girls with CPP compared with the monotherapy regimen, which was not cost-effective for residents in rural areas, but it was cost-effective for residents in urban areas. One-way sensitivity analysis showed that the uncertain factors with potential impacts on the results were, in order, the price of rhGH, the final height of pediatric patients in the combination therapy regimen group, the course of rhGH in the combination therapy regimen group, and the final height of pediatric patients in the monotherapy regimen group. Probabilistic sensitivity analysis indicated that the probability of the combination therapy regimen being cost-effective was higher than that of the monotherapy regimen when WTP was more than 26 010 yuan/cm. When GnRHa long-acting preparation was used for intramuscular injection every 3 months, the combination therapy regimen was not cost-effective for rural residents, but was cost-effective for urban residents; when rhGH long-acting preparation was injected subcutaneously once a week, the combination therapy regimen was not cost-effective for residents in both rural areas and urban areas. CONCLUSIONS The combination of GnRHa and rhGH is only recommended for CPP children with better affordability to improve final height. The benefits, risks, and affordability of treatment should be comprehensively considered before the decisions on pharmacotherapy, to avoid abuse of rhGH due to the blind pursuit of height growth.

AIM: To investigate the effects of insulin-like growth factor 1(IGF-1)on the secretion of transforming growth factor β2(TGF-β2), matrix metalloproteinase 2(MMP-2)and hypoxia-inducible factor 1α(HIF-1α)in human scleral fibroblasts(HSF)and their mechanism.METHODS: The cells were cultured with IGF-1 and PI3K/AKT pathway inhibitor LY294002, respectively. CCK-8 method was used to detect cell viability and determine the optimal concentration and time of drug action. Cell migration activity was observed by cell scratch method. To determine the effects of IGF-1 on HSF cells and the regulatory role of PI3K/AKT pathway, HSF cells were divided into control group(without drugs), IGF-1(80 μg/L)group, IGF-1+LY294002(80 μg/L+5 mmol/L)group, and LY294002(5 mmol/L)group, and were cultured for 24 h; the protein expression levels of TGF-β2, MMP-2, HIF-1α, PI3K and AKT were detected by Western blot; the fluorescence expression of TGF-β2, MMP-2 and HIF-1α was detected by cellular immunofluorescence.RESULTS: The results of CCK-8 showed that the cell viability of the 80 μg/L IGF-1 group cultured with different concentrations of IGF-1 was the highest(all P<0.05), and the cell viability of the 80 μg/L IGF-1 group at 24 h was the highest under different culture times. Therefore, the concentration of IGF-1 was selected as 80 μg/L for 24 h. The viability of cells cultured with different concentrations of LY294002 gradually decreased from 6 h(all P<0.05). According to the IC50 value, therefore, the concentration of LY294002 was selected as 5 mmol/L for 24 h. The cell scratch results showed that compared with the control group, the cell mobility of 40 μg/L and 80 μg/L IGF-1 groups was increased(all P<0.05). Compared with the control group, cell mobility in the 2.5 and 5 mmol/L LY294002 groups was decreased(all P<0.05). Western blot results showed that compared with the control group, the protein expressions of TGF-β2, MMP-2, HIF-1α, PI3K and AKT in the IGF-1 group were increased, while those in the LY294002 group were decreased(all P<0.05). Compared with the IGF-1 group, the expression levels of TGF-β2, MMP-2, HIF-1α, PI3K and AKT in the IGF-1+LY294002 group were decreased(all P<0.05). The results of cell immunofluorescence showed that compared with the control group, the fluorescence expressions of TGF-β2, MMP-2 and HIF-1α in the IGF-1 group were increased, while those in the LY294002 group were decreased(all P<0.05). Compared with the IGF-1 group, the fluorescence expressions of TGF-β2, MMP-2 and HIF-1α in the IGF-1+LY294002 group were significantly decreased(all P<0.05).CONCLUSION: IGF-1 promoted the proliferation and migration of human HSF. IGF-1 may up-regulate the expression of TGF-β2, MMP-2 and HIF-1α in HSF through the PI3K/AKT signaling pathway, and participate in the occurrence and development of myopia.

The innate immune system can be boosted in response to subsequent triggers by pre-exposure to microbes or microbial products, known as “trained immunity”. Compared to classical immune memory, innate trained immunity has several different features. Firstly, the molecules involved in trained immunity differ from those involved in classical immune memory. Innate trained immunity mainly involves innate immune cells (e.g., myeloid immune cells, natural killer cells, innate lymphoid cells) and their effector molecules (e.g., pattern recognition receptor (PRR), various cytokines), as well as some kinds of non-immune cells (e.g., microglial cells). Secondly, the increased responsiveness to secondary stimuli during innate trained immunity is not specific to a particular pathogen, but influences epigenetic reprogramming in the cell through signaling pathways, leading to the sustained changes in genes transcriptional process, which ultimately affects cellular physiology without permanent genetic changes (e.g., mutations or recombination). Finally, innate trained immunity relies on an altered functional state of innate immune cells that could persist for weeks to months after initial stimulus removal. An appropriate inducer could induce trained immunity in innate lymphocytes, such as exogenous stimulants (including vaccines) and endogenous stimulants, which was firstly discovered in bone marrow derived immune cells. However, mature bone marrow derived immune cells are short-lived cells, that may not be able to transmit memory phenotypes to their offspring and provide long-term protection. Therefore, trained immunity is more likely to be relied on long-lived cells, such as epithelial stem cells, mesenchymal stromal cells and non-immune cells such as fibroblasts. Epigenetic reprogramming is one of the key molecular mechanisms that induces trained immunity, including DNA modifications, non-coding RNAs, histone modifications and chromatin remodeling. In addition to epigenetic reprogramming, different cellular metabolic pathways are involved in the regulation of innate trained immunity, including aerobic glycolysis, glutamine catabolism, cholesterol metabolism and fatty acid synthesis, through a series of intracellular cascade responses triggered by the recognition of PRR specific ligands. In the view of evolutionary, trained immunity is beneficial in enhancing protection against secondary infections with an induction in the evolutionary protective process against infections. Therefore, innate trained immunity plays an important role in therapy against diseases such as tumors and infections, which has signature therapeutic effects in these diseases. In organ transplantation, trained immunity has been associated with acute rejection, which prolongs the survival of allografts. However, trained immunity is not always protective but pathological in some cases, and dysregulated trained immunity contributes to the development of inflammatory and autoimmune diseases. Trained immunity provides a novel form of immune memory, but when inappropriately activated, may lead to an attack on tissues, causing autoinflammation. In autoimmune diseases such as rheumatoid arthritis and atherosclerosis, trained immunity may lead to enhance inflammation and tissue lesion in diseased regions. In Alzheimer’s disease and Parkinson’s disease, trained immunity may lead to over-activation of microglial cells, triggering neuroinflammation even nerve injury. This paper summarizes the basis and mechanisms of innate trained immunity, including the different cell types involved, the impacts on diseases and the effects as a therapeutic strategy to provide novel ideas for different diseases.

Virus-related lymphoma exhibits a dual nature as both a hematologic malignancy and a viral infectious disease, making it more resistant to treatment and associated with poorer prognosis. This paper analyzes the understanding and therapeutic advantages of traditional Chinese medicine (TCM) in virus-related lymphoma. It proposes a TCM-based approach centered around syndrome differentiation, using standardized measurements of the overall TCM condition, multi-omics research of hematologic tumors, and artificial intelligence technologies to identify the "pre-condition" of virus-related lymphoma. A risk warning model will be established to early identify high-risk populations with viral infections that may develop into malignant lymphoma, thereby establishing a risk warning system for virus-related lymphoma. At the same time, a TCM health management approach will be applied to manage and regulate virus-related lymphoma, interrupting its progression and forming a human-centered, comprehensive, continuous health service model. Based on this, a standardized, integrated clinical prevention and treatment decision-making model for virus-related lymphoma, recognized by both Chinese and western medicine, will be established to provide TCM solutions for primary prevention of major malignant tumors.

ObjectiveTo screen and evaluate the antidepressant compounds of Curcumae Rhizoma, and explore its mechanism of regulating the nuclear factor erythroid 2-related factor 2(Nrf2)/glutathione(GSH) peroxidase 4(GPX4)/GSH pathway from an antioxidant perspective. MethodsThe antioxidant activities in vitro of 11 characteristic components from Curcumae Rhizoma, including curcumol, curgerenone, curdione, curzerene, curcumenol, curcumenone, dehydrocurdione, isocurcumenol, furanodienone, furanodiene and zederone, were detected using 1,1-diphenyl-2-picrylhydrazyl(DPPH) and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt(ABTS) radical scavenging assays. The depression in Drosophila melanogaster was induced by chronic unpredictable mild stress(CUMS), and W1118 wild-type male D. melanogaster were randomly divided into blank group, model group, curcumol group, curgerenone group, curdione group, curzerene group, curcumenol group,curcumenone group, dehydrocurdione group, isocurcumenol group, furanodienone group, furanodiene group, zederone group and fluoxetine group(10 μmol·L-1). The treatment groups received a dose of 0.1 g·L-1 of 11 characteristic components from Curcumae Rhizoma, while the blank and model groups were administered equivalent volumes of solvent. The sucrose preference test, climbing test and forced swimming test were used to evaluate the behavioral indicators of depression in D. melanogaster. Liquid chromatography-mass spectrometry(LC-MS) was used to detect the levels of 5-hydroxytryptamine(5-HT) and dopamine(DA) in the brain of D. melanogaster, and the entropy weight method was used to comprehensively evaluate neurobehavioral and neurotransmitter indicators, resulting in the identification of the antidepressant active components of Curcumae Rhizoma. In addition, a mouse depression model was established by CUMS, and C57BL/6J mice were randomly divided into blank group, model group, low and high dose groups of curzerene(0.5, 1 mg·kg-1), and fluoxetine group(10 mg·kg-1) to confirm the antidepressant effect of the optimal active ingredient by behavioral analysis. Flow cytometry was used to detect the content of reactive oxygen species(ROS) in the hippocampus of mice from each group. Enzyme-linked immunosorbent assay was used to detect the contents of adenosine triphosphate(ATP), superoxide dismutase(SOD), catalase(CAT) and GSH. Transmission electron microscope(TEM) was used to observe the effect of curzerene on the ultrastructure of mitochondria in hippocampal tissue. Western blot was performed to determine the level of Nrf2 protein, and Nrf2 inhibitor(ML385) was used to verify the relationship between the antidepressant effect of curzerene and regulation of Nrf2. Real time fluorescence quantitative polymerase chain reaction(Real-time PCR) was employed to detect the effect of curzerene on the mRNA expression level of GPX. ResultsIn vitro antioxidant experiments showed that curzerene and curgerenone exhibited the most significant ability to scavenge free radicals, and comprehensive evaluation results of entropy weight method indicated that curzerene stood out as the most promising active component. Compared with the blank group, the model group exhibited a significant decrease in sucrose preference coefficient and the number of times entering the open field center(P<0.01), as well as a significant increase in immobility time in the forced swimming and tail suspension tests(P<0.01), and the ROS content in hippocampus significantly elevated(P<0.01), while the ATP content significantly reduced(P<0.01). In the hippocampal neurons of the model group, mitochondrial cristae were disordered, with vacuolation of the inner membrane and severe damage. Nrf2 protein expression level in the model group was significantly decreased(P<0.05), and the antioxidant enzymes SOD, CAT and GSH contents were also significantly reduced(P<0.05, P<0.01), and the gene expression levels of GPX1, GPX4 and GPX7 were significantly decreased(P<0.01). Compared with the model group, the high-dose group of curzerene showed a significant increase in the sucrose preference coefficient and the number of times entering the open field center(P<0.05), as well as a significant decrease in immobility time in the forced swimming and tail suspension tests(P<0.05, P<0.01). The ROS content in the hippocampus of the high-dose group of curzerene was significantly reduced(P<0.01), while the ATP content was significantly increased(P<0.05). The neuronal mitochondrial damage in the hippocampus of the high-dose group of curzerene was alleviated, and the expression level of Nrf2 protein was significantly increased(P<0.05). The Nrf2 inhibitor ML385 reversed the improvement of curzerene on depressive behaviors in CUMS mice. The GSH content in the hippocampal neurons of the high-dose group of curzerene was significantly increased(P<0.01), while there were no significant differences in SOD and CAT contents. The expression level of GPX4 gene in the hippocampal neurons of the high-dose group of curzerene was significantly increased(P<0.05), while there were no significant differences in other GPX genes. ConclusionCurzerene is the best component with antidepressant activity in Curcumae Rhizoma. It may improve mitochondrial dysfunction to exert its antidepressant effect by regulating Nrf2 and its downstream GPX4/GSH pathway rather than CAT or SOD pathways.

AIM: To evaluate the repeatability and accuracy of iCare IC100 tonometer in measuring intraocular pressure(IOP)by comparing the correlation and difference with Goldmann applanation tonometry(GAT)and non-contact tonometer(NCT), and to compare the correlation of the three types of IOP measurement with the central corneal thickness(CCT).METHODS: Prospective study. A total of 90 outpatients(90 eyes)in Liaoning Aier Eye Hospital from March 2019 to May 2019 were randomly selected as study subjects. All patients were measured IOP using iCare IC100, NCT, and GAT. The interclass correlation coefficient(ICC)was used to evaluate the repeatability of IOP measured 3 times consecutively using an intraocular tonometer. The correlation and consistency of iCare IC100, GAT and NCT were compared by one-way ANOVA, Pearson linear correlation analysis and Bland-Altman analysis. The linear regression analysis was used to analyze the correlation of the three tonometers with CCT.RESULTS: The mean IOP measured with iCare IC100, GAT and NCT was 19.74±6.90, 19.88±7.07 and 18.47±6.31 mmHg, respectively(F=1.180, P=0.309). The measurements of iCare IC100 with GAT, iCare IC100 with NCT and GAT with NCT were all positively correlated(r=0.930, 0.946, 0.918, all P<0.05), the Bland-Altman analysis showed that the mean differences between iCare IC100 and GAT, iCare IC100 and NCT, GAT and NCT were -0.142±2.61, 1.27±2.24, and 1.41±2.81 mmHg, respectively, with 97%(87/90), 96%(86/90), and 97%(87/90)IOP differences distributed within their 95% confidence intervals. The IOP measured with iCare IC100 and CCT, GAT and CCT and NCT and CCT were all positively correlated(r=0.426, 0.353, 0.451, all P<0.01). The linear regression equations between iCare IC100, GAT and NCT measurement and CCT were iCare IC100 IOP=-19.62+0.074×CCT; GAT IOP=-13.54+0.063×CCT; NCT IOP=-19.65+0.072×CCT; that is, for every 10 μm increase in CCT, iCare IC100 measurement increased by 0.74 mmHg, GAT measurement increased by 0.63 mmHg, and NCT measurement increased by 0.72 mmHg.CONCLUSION: The iCare IC100 tonometer has good repeatability and accuracy in measuring IOP, and the CCT has a greater impact on the measurement of iCare IC100 than the GAT and NCT.
