ObjectiveTaking Aurantii Fructus Immaturus juice(AFI)-processed Atractylodis Macrocephalae Rhizoma(AMR) as an example, this study aims to systematically compare the volatile and non-volatile components of AMR and its processed products, investigate the key differential components, evaluate their anti-inflammatory activities, and elucidate the synergistic mechanism of processing. MethodsThe chemical compositions of volatile and non-volatile components in AMR and AFI-processed AMR were systematically characterized using gas chromatography-mass spectrometry(GC-MS) and ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS), with relative mass fractions and response values determined separately. Volatile components were identified through searches in the National Institute of Standards and Technology(NIST)17 database, comparison with retention index(RI) and fragmentation pattern matching. Non-volatile components were identified by searching Waters Traditional Chinese Medicine (TCM) spectral library, in conjunction with PubChem and MassBank, characteristic fragmentation patterns and response values were also used to support identification. Differential components were screened using principal component analysis(PCA), orthogonal partial least squares-discriminant analysis(OPLS-DA), with variable importance in the projection(VIP) value >1. Components with high log2fold change(FC) among major differential groups were selected as those exhibiting significant changes before and after processing. The anti-inflammatory activity of the differential compounds was evaluated by assessing their effects on nitric oxide(NO) production in a lipopolysaccharide(LPS)-induced RAW264.7 macrophage model. Enzyme-linked immunosorbent assay(ELISA) was used to detect the effects of the differential components on tumor necrosis factor(TNF)-α, interleukin(IL)-1β, IL-6, and monocyte chemotactic protein(MCP)-1 levels, and immunofluorescence(IF) was employed to assess their effects on nuclear transcription factor(NF)-κB p65 translocation, thereby elucidating the underlying molecular mechanisms. ResultsA total of 36 compounds were identified in the volatile components of AMR and AFI-processed AMR, among which, sesquiterpenes and monoterpenes were significantly increased after processing. In the non-volatile components, 36 compounds were identified, and the main differential components were flavonoids, sesquiterpenoids, and triterpenoids. Flavonoids were the primary differential components distinguishing AMR from its processed products, representing compounds directly introduced during processing. Five compounds, including atractylenolide Ⅲ, tangeritin, nobiletin, hesperidin and narirutin, were selected as representatives of three classes based on their most prominent differential expression among different compound types for subsequent anti-inflammatory activity studies. The results showed that 100 μmol·L-1 tangerine and narirutin could significantly inhibit LPS-induced NO production(P<0.01) in a concentration-dependent manner. Tangeritin was able to significantly inhibit the levels of TNF-α and MCP-1 secreted by RAW264.7(P<0.05), while narirutin significantly inhibited the levels of TNF-α, IL-1β, MCP-1 and IL-6(P<0.01). IF revealed that both tangeritin and narirutin significantly blocked the translocation of NF-κB p65 from the cytoplasm to the nucleus. ConclusionAFI-processed AMR significantly alters the chemical composition profile of AMR, and the newly introduced flavonoid components during processing may be key to its enhanced anti-inflammatory effects.

OBJECTIVE To compare the antihypertensive efficacy of sacubitril/valsartan versus benazepril in patients with perimenopausal hypertension, as well as their impacts on ventricular remodeling and inflammatory fibrosis. METHODS A total of 206 perimenopausal hypertensive patients in our hospital from January 1, 2023 to December 30, 2024 were retrospectively included.These patients were enrolled and divided into benazepril group (105 cases) and sacubitril/valsartan group (101 cases). Benazepril group received Benazepril hydrochloride tablet, and sacubitril/valsartan group received Sacubitril valsartan sodium tablet. All patients were treated for 6 months. The blood pressure(systolic blood pressure and diastolic blood pressure) and blood pressure control status before and after treatment, echocardiographic indicators (left ventricular ejection fraction, left ventricular mass index, relative wall thickness, and early-diastolic peak transmitral flow velocity/early-diastolic peak velocity of the mitral annulus), inflammatory fibrosis related indicators(high-sensitivity C-reactive protein,ratio of monocytes to lymphocytes,and ratio of neutrophils to lymphocytes), as well as the occurrence of adverse reactions(hypotension,hyperkalemia,and angioedema) were observed in both groups before and after treatment. RESULTS The blood pressure control rate was significantly higher in the sacubitril/valsartan group than in benazepril group ( P <0.05). After treatment, the blood pressure, echocardiographic indicators(except for left ventricular ejection fraction) ,and inflammatory fibrosis related indicators were significantly lower than those before treatment within the same group, and the sacubitril/valsartan group were significantly lower than the benazepril group ( P <0.05). There were no statistically significant differences in the incidence of hypotension, hyperkalemia, angioedema, and overall adverse drug reactions between the two groups ( P >0.05). CONCLUSIONS Compared with benazepril, sacubitril/valsartan provides superior blood-pressure control, reverses ventricular remodeling, attenuates inflammatory fibrosis in perimenopausal hypertensive patients, while maintaining a similar safety profile.

BACKGROUND:The diabetic microenvironment can cause excessive M1 polarization of macrophages,and this hyperglycemic inflammatory state can inhibit osteogenic differentiation of bone marrow mesenchymal stem cells,thus affecting the healing of diabetic bone defects.Studies have indicated that mogroside V possesses anti-inflammatory,antioxidant,and hypoglycemic properties.However,its potential to modulate M1 polarization of macrophages and osteogenic differentiation of bone marrow mesenchymal stem cells under high glucose and inflammatory condition remains unclear. OBJECTIVE:To explore the effect of mogroside V on regulating M1 macrophage polarization and its effect on osteogenic differentiation of bone marrow mesenchymal stem cells under high glucose and inflammatory condition. METHODS:Murine diabetic models were established using C57BL/6 mice.Bone marrow-derived macrophages were isolated from tibia and fibula of normal and diabetic mice,and cultured in low-glucose and high-glucose media.Then M1 polarization of bone marrow-derived macrophages was induced using lipopolysaccharide and interferon-γ.Bone marrow-derived macrophages were treated with 160,320,and 640 μmol/L mogroside V.Flow cytometry was employed to determine the proportion of F4/80+CD86+cells.qRT-PCR was utilized to assess mRNA expression levels of inducible nitric oxide synthase,interleukin 1β,and interleukin 6.ELISA was employed to evaluate tumor necrosis factor-α secretion in bone marrow-derived macrophage supernatants.Bone marrow mesenchymal stem cells were isolated from tibia and fibula of C57BL/6 suckling mice,and induced osteogenic differentiation using low-or high-glucose osteogenic induction medium.Bone marrow mesenchymal stem cells were treated with M1 macrophage-conditioned mediums with or without 320 μmol/L mogroside V in osteogenic differentiation process.qRT-PCR was employed to assess the mRNA expression of alkaline phosphatase,Runt-related factor 2,osteocalcin,and osteopontin on day 14 after osteogenic induction.Alizarin red staining and quantitative analysis were conducted to evaluate calcium deposition on day 21 after osteogenic induction. RESULTS AND CONCLUSION:(1)Flow cytometry results showed that with the treatment of 320 and 640 μmol/L mogroside V,the proportion of F4/80+CD86+bone marrow-derived macrophages was significantly lower than that in the high-glucose control group(P<0.05).(2)qRT-PCR results showed that with the treatment of 160,320,and 640 μmol/L mogroside V,the mRNA expression levels of inducible nitric oxide synthase and interleukin 6 were significantly lower than that in the high-glucose control group(P<0.05).With the treatment of 320 and 640 μmol/L mogroside V,the mRNA expression level of interleukin 1β was significantly lower than that in the high-glucose control group(P<0.05).(3)ELISA results exhibited that with the treatment of 160,320,and 640 μmol/L mogroside V,the tumor necrosis factor-α secretion level was significantly lower than that in the high-glucose control group(P<0.05).(4)With the treatment of 320 μmol/L mogroside V,calcium salt deposition was increased in bone marrow mesenchymal stem cells under high glucose and inflammatory conditions(P<0.05),and the mRNA relative expression levels of alkaline phosphatase,Runt-related factor 2,and osteopontin were increased(P<0.05).These findings indicate that mogroside V can promote osteogenic differentiation of bone marrow mesenchymal stem cells by inhibiting the M1 polarization of bone marrow-derived macrophages under high glucose and inflammatory conditions and reducing the generation of inflammatory factors.

Objective:
To explore the types of medication adherence and their influencing factors among inpatients with chronic diseases based on latent profile analysis, so as to provide the basis for improving medication adherence among patients with chronic diseases.
Methods:
The inpatients with chronic diseases admitted to the Second Affiliated Hospital of Hainan Medical University were selected as the study subjects. Demographic information, chronic disease status, and health education were collected through questionnaire surveys. Medication adherence was assessed using the Medication Adherence Scale and categorized based on the scores of its eight items through latent profile analysis. Factors affecting medication adherence among inpatients with chronic diseases were analyzed using a multinomial logistic regression model.
Results:
Totally 290 valid questionnaires were recovered, with an effective recovery rate of 97.64%. There were 157 males (54.14%) and 133 females (45.86%), with a median age of 61 (interquartile range, 21) years. The median score of medication adherence was 4.75 (interquartile range, 4.50). Based on latent profile analysis, medication adherence was categorized into three types: subjective neglect with poor adherence (38.97%), subjective confidence with fluctuating adherence (28.28%), and self-reflective with good adherence (32.76%). Multinomial logistic regression analysis showed that compared to the subjective confidence with fluctuating adherence, family monthly income (5 000-10 000 yuan, OR=2.981, 95%CI: 1.055-8.429), comorbidity of chronic diseases (OR=3.478, 95%CI: 1.579-7.661), number of health education sessions received in the past year (≤1 session, OR=0.329, 95%CI: 0.120-0.907; 2 sessions, OR=0.363, 95%CI: 0.138-0.950), and health information literacy scores (<60 points, OR=2.596, 95%CI: 1.209-5.573) were statistically associated with subjective neglect with poor adherence (all P<0.05).
Conclusion
Subjective neglect with poor medication adherence among inpatients with chronic diseases is associated with family monthly income, comorbidity of chronic diseases, the number of health education sessions received, and health information literacy.

Objective:
To investigate the prevalence and influencing factors of menopausal syndrome among postmenopausal women in Pan'an County, Zhejiang Province, so as to provide the basis for guiding the health management of postmenopausal women.
Methods:
From May 2023 to April 2024, the postmenopausal women aged 40 to 69 years in Pan'an County were selected using the random cluster sampling method. Demographic information, lifestyle and prevalence of gynecological diseases were collected through questionnaire surveys. The prevalence of menopausal syndrome was assessed by modified Kupperman Score Scale. Factors affecting menopausal syndrome were analyzed by a multivariable logistic regression model.
Results:
A total of 816 postmenopausal women were surveyed, with an mean age of (57.63±2.92) years and a mean natural menopause age of (49.85±2.13) years. There were 574 cases with menopausal syndrome, with a prevalence of 70.34%. Flashes and sweating, insomnia and irritability were common symptoms, accounting for 62.87%, 47.43% and 41.18%, respectively. Multivariable logistic regression analysis showed that monthly personal income of ≤5 000 yuan (<3 000 yuan, OR=3.124, 95%CI: 1.829-5.335; 3 000-5 000 yuan, OR=2.399, 95%CI: 1.370-4.201) and having gynecological diseases (OR=1.970, 95%CI: 1.292-3.004) were associated with a higher risk of menopausal syndrome, while average (OR=0.141, 95%CI: 0.072-0.276) or sufficient sleep quality (OR=0.095, 95%CI: 0.049-0.185) were associated with a lower risk of menopausal syndrome.
Conclusion
The prevalence of menopausal syndrome among postmenopausal women in Pan'an County is relatively high, and is mainly influenced by personal economic status, sleep quality and the presence of gynecological diseases.

ObjectiveTo observe and compare the effects of different concentrations of cyclophosphamide (CTX) in inducing premature ovarian insufficiency (POI) model in mice and investigate the mechanism of injury. MethodsThirty-two 6~8-week-old female C57BL/6J mice were randomly divided into four groups (n=8 per group) using a weight-based block randomization method. The POI model was established via a single intraperitoneal injection of 75 mg/kg cyclophosphamide (CTX), 120 mg/kg CTX, 120 mg/kg CTX + 12 mg/kg Busulfan, or an equivalent volume of normal saline (control). Ovarian coefficients, serum estradiol (E2) and follicle-stimulating hormone (FSH) levels were measured. Western blotting was performed to assess changes in ovarian expression levels of NAD-dependent deacetylase sirtuin-5 (SIRT5) and forkhead box O3a (FOXO3a) under different modeling conditions. After determining the optimal CTX concentration for modeling, an additional forty 6~8-week-old femal C57BL/6J mice were randomly divided into five groups (n=8 per group) using a weight-based block randomization method: saline control, 120 mg/kg CTX sampling at 1, 2, 7, or 14 days after modeling. Western blotting was used to evaluate temporal changes of ovarian SIRT5 and FOXO3a protein expression. ResultsCompared with the saline control, all concentrations of CTX (75 mg/kg CTX, 120 mg/kg CTX) and 120 mg/kg CTX + 12 mg/kg Busulfan induced POI injury in mice. The 120 mg/kg CTX group exhibited smaller changes in ovarian coefficients (P<0.001) and E2 levels (P<0.05), whereas the 120 mg/kg CTX + 12 mg/kg Busulfan group showed rough and reduced luster fur, sluggish response and was in the worst state. Compared with the saline control group, FOXO3a expression was significantly down-regulated (P<0.05), while SIRT5 remained unchanged in the 75 mg/kg CTX group (P>0.05). In contrast, both SIRT5 (P<0.05) and FOXO3a (P<0.05) were significantly down-regulated in the 120 mg/kg CTX group. Further analysis revealed that on day 2 and 7 after 120 mg/kg CTX modeling, the expressions of SIRT5 (P<0.01) and FOXO3a (P<0.001) were significantly down-regulated, with the largest decrease observed on day 7 (SIRT5, P<0.000 1; FOXO3a, P<0.000 1). ConclusionOvarian injury in the POI model induced by 120 mg/kg CTX is milder than that in the POI model induced by 75 mg/kg CTX. Moreover, the expression changes of SIRT5 and FOXO3a are most significant on day 7 after modeling induced by 120 mg/kg CTX, which may be related to the inhibition of the SIRT5-FOXO3a signaling pathway.

ObjectiveThe full name of vertebroplasty is percutaneous vertebroplasty (PVP). It is a clinical technique that injects bone cement into the diseased vertebral body to achieve strengthening of the vertebra. The research on the safety and efficacy of bone cement is the basis for clinical application. In this study, vertebroplasty is used to evaluate and compare the safety and efficacy of Tecres and radiopaque bone cement in experimental pigs, and to determine the puncture method suitable for pigs and the pre-clinical evaluation method for the safety and efficacy of bone cement. MethodsTwenty-four experimental pigs (with a body weight of 60-80 kg) were randomly divided into an experimental group (Group A) and a control group (Group B). Group A was the Tecres bone cement group, and Group B was the radiopaque bone cement group, with 12 pigs in each group. Under the monitoring of a C-arm X-ray machine, the materials were implanted into the 1st lumbar vertebra (L1) and 4th lumbar vertebra (L4) of the pigs via percutaneous puncture using the unilateral pedicle approach. The animals were euthanized at 4 weeks and 26 weeks after the operation, respectively. The L4 vertebrae were taken for compressive strength testing, and the L1 vertebrae were taken for hard tissue pathological examination to observe the inflammatory response, bone necrosis, and degree of osseointegration at the implantation site. ResultsThe test results of compressive strength between groups A and B showed no significant difference at 4 weeks and 26 weeks after bone cement implantation (P > 0.05). Observation under an optical microscope (×100) revealed that at 4 weeks postoperatively, both groups A and B showed that the bone cement was surrounded by proliferative fibrous tissue, with lymphocyte infiltration around it. The bone cement was combined with bone tissue, the trabecular arrangement was disordered, and osteoblasts and a small amount of osteoid were formed. At 26 weeks postoperatively, bone cement was visible in both groups A and B. The new bone tissue was mineralized, the trabeculae were fused, the trabecular structure was regular and dense with good continuity, and no obvious inflammatory reaction was observed. ConclusionIn experimental pig vertebrae, there were no significant differences observed in the compressive strength, inflammation response, bone destruction, and integration with the bone between Tecres and non-radiopaque bone cement. Both exhibited good biocompatibility and osteogenic properties. It indicates that using vertebroplasty to evaluate the safety and efficacy of bone cement in pigs is scientifically sound.

BackgroundNon-suicidal self-injury (NSSI) behavior among adolescents has become a global public health concern. Anxiety and depression are considered key factors influencing NSSI behavior, while social support may play a protective role in alleviating emotional and behavioral issues. However, existing research has primarily focused on the direct impact of individual factors on NSSI behavior, with insufficient exploration of the combined effects of anxiety, depression and social support. ObjectiveTo investigate the direct effect of anxiety on NSSI, the mediating role of depression and the moderating role of social support in relationship between anxiety and NSSI behavior, thus to provide references for the prevention and intervention of NSSI behavior among adolescents. MethodsIn February 2022, a total of 40 820 students in grades 7 to 12 across 10 middle schools in a district of Chengdu were selected as participants, and they were assessed using Generalized Anxiety Disorder Scale-7 item (GAD-7), Patient's Health Questionnaire Depression Scale-9 item (PHQ-9), Social Support Scale for Urban Students (SSSUS) and Adolescent Self-Harm Scale (ASHS). Pearson correlation analysis was conducted to examine the correlations between scale scores among adolescents with NSSI behaviors. Mediation and moderation analyses were performed using Process 3.5 in SPSS, and the significance was tested with bootstrapping. The interaction was visualized by using simple slope analysis. ResultsAmong 34 534 (84.60%) valid respondents, 542 adolescents (1.57%) reported engaging in NSSI behavior. Significant differences in gender, GAD-7 scores, PHQ-9 scores, and SSSUS scores were observed between NSSI behavior group and non-NSSI group (χ²/t=62.889, 71.120, 94.365, -41.464, P<0.01).Adolesents with NSSI showed positive correlations between GAD-7 scores and both ASHS and PHQ-9 scores (r=0.158, 0.166, P<0.01). PHQ-9 scores were positively correlated with ASHS scores (r=0.364, P<0.01), but negatively correlated with SSSUS scores (r=-0.290, P<0.01). SSSUS scores were negatively correlated with ASHS scores (r=-0.247, P<0.01). Depression partially mediated the relationship between anxiety and NSSI behavior, with an effect size of 0.544 (95% CI: 0.162~0.944), accounting for 35.79% of the total effect. Social support moderated the relationship between depression and NSSI bahavior, with an effect value of -0.082 (95% CI: -0.135~-0.029). ConclusionAnxiety not only directly influences NSSI bahavior among adolescents, also indirectly exacerbates it through depression, while social support mitigates the impact of depression on NSSI behavior.

OBJECTIVE:
To establish a similarity measurement model for patients with dentofacial deformity based on 3D craniofacial features and to validate the similarity results with quantifying subjective expert scoring.
METHODS:
In the study, 52 cases of patients with skeletal Class Ⅲ malocclusions who underwent bimaxillary surgery and preoperative orthodontic treatment at Peking University School and Hospital of Stomatology from January 2020 to December 2022, including 26 males and 26 females, were selected and divided into 2 groups by sex. One patient in each group was randomly selected as a reference sample, and the others were set as test samples. Three senior surgeons rated the similarity scores between the test samples and the reference sample. Similarity scores ranged from 1 to 10, where 1 was completely different, and 10 was exactly the same. Scores larger than 7.5 was considered as clinically similar. Preoperative cone beam computed tomography (CBCT) and 3D facial images of the patients were collected. The three-dimensional hard and soft tissue features, including distances, angles and 3D point cloud features were extracted. The similarity measurement model was then established to fit with the experts' similarity scoring by feature selection algorithm and linear regression model. To verify the reliability of the model, 14 new patients were selected and input to similarity measurement model for finding similar cases. The similarity scoring of these similar cases were rated by experts, and used to evaluate the reliability of the model.
RESULTS:
The similarity metric models indicated that the features of the middle and lower craniofacial features were the main features to influence the craniofacial similarity. The main features that were related to the expert' s similarity scoring included distance of anterior nasal spine-menton (ANS-Me), distance of right upper canion point-Frankfurt horizontal plane (U3RH), distance of left superior point of the condyle-left gonion (CoL-GoL), distance of left gonion-menton (CoL-Me), distance of pogonion-midsagittal plane (Pog-MSP), distance of right alar base-left alar base (AlR-AlL), angle of pronasale-soft tissue pogonion-labrale inferius (Pn-Pog' -Li), distance of trichion-right tragus (Tri-TraR), distance of left exocanthion-left alar base (ExL-AlL), lower 1/3 of skeletal face, middle and lower 2/3 of skeletal face and upper lip region of soft tissue. Fourteen new patients were chosen to evaluate the model. The similar cases selected by the model had an average experts' similarity scoring of 7.627± 0.711, which was not significantly different with 7.5.
CONCLUSION
The similarity measurement model established by this model could find the similar cases which highly matched experts' subjective similarity scoring. The study could be further used for similar cases retrieval in skeletal Ⅲ malocclusion patients.
