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 systematically evaluate the effects of oral non-peptidic thrombopoietin receptor agonists （TPO-RAs） on hepatic enzyme in adult patients with immune thrombocytopenia. METHODS A comprehensive literature search was conducted in PubMed， Web of Science， CNKI， Wanfang database and the Chinese Medical Association Journal Full-Text Database to collect randomized controlled trials （RCTs） comparing oral non-peptidic TPO-RAs （intervention group） with placebo or conventional therapy （control group）. All databases were searched from their inception to June 2025. After literature screening， data extraction and quality assessment of the included studies， meta-analysis was conducted using RevMan 5.4.1 software. RESULTS Twelve RCTs comprising 1 388 patients were included， with 971 in the intervention group and 417 in the control group. Meta-analysis results showed that there were no significant differences between the two groups in terms of the incidence of hepatic enzyme elevation[OR＝1.24， 95%CI （0.77， 1.99）， P ＝0.37 ] ， the incidence of hepatic enzyme elevation in patients treated for ≥6 weeks[OR＝1.21， 95%CI （0.73， 1.99）， P ＝0.46 ] ， and the incidence of severe hepatic enzyme elevation[OR＝1.39， 95%CI（0.46， 4.20）， P ＝0.55 ] . Subgroup analysis showed that there were no significant differences in the incidence of hepatic enzyme elevation between the intervention group and control group among patients using eltrombopag[OR＝1.57，95%CI（0.85，2.87）， P ＝0.15 ] ， avatrombopag[OR＝0.88，95%CI （0.09，8.46）， P ＝0.91 ] ， and hetrombopag[OR＝1.04，95%CI（0.30，3.65）， P ＝0.95 ] ， respectively. CONCLUSIONS Oral non-peptidic TPO-RAs do not significantly increase the risk of hepatic enzyme elevation in adult patients with immune thrombocytopenia， and show an overall favorable hepatic safety profile.

Objective: To investigate the changes in oropharyngeal airway parameters and hyoid position in skeletal ClassⅡ adult female patients with different vertical skeletal types who were treated with maxillary anterior teeth retraction with maximum anchorage, and to provide a reference for orthodontic clinical diagnosis and treatment. Methods: This study was reviewed and approved by the Medical Ethics Committee, and informed consent was obtained from patients. Sixty adult female patients with skeletal ClassⅡ were selected and divided into a skeletal ClassⅡ normodivergent group and a skeletal ClassⅡ hyperdivergent group based on the patients’ mandibular plane angle. In both groups, the bilateral maxillary first premolars were extracted and the maxillary anterior teeth were retracted with maximum anchorage. Cone beam CT(CBCT) images were collected before and after treatment, and three-dimensional measurement software was used to analyze oropharyngeal airway-related parameters. Results: After retraction of the maxillary anterior teeth with maximum anchorage, the 10 parameters related to the oropharyngeal airway did not exhibit statistically significant differences in the normodivergent group (P>0.05), but the perpendicular distance from the highest point of the hyoid bone to the vertical line passing through the sella (H-X) value decreased (P<0.001). In the hyperdivergent group, the oropharyngeal area at the level of the epiglottis tip (OPA-E), anterior-posterior diameters of the oropharynx at the level of the epiglottis tip (E-AP), most constricted axial area of the oropharynx (OPA-MCA), and anterior-posterior diameters of MCA area of the oropharynx (MCA-AP) decreased after treatment (P<0.001). In addition, the oropharyngeal volume (OPV) decreased after treatment (P<0.05), and the perpendicular distance from the highest point of the hyoid bone to the horizontal line passing through the sella (H-Y) and the highest point of the hyoid bone to the epiglottis base (H-Eb) values increased after treatment (P<0.05). Conclusion After retraction of the maxillary anterior teeth with maximum anchorage, there is no change in the oropharyngeal airway in skeletal ClassⅡ normodivergent female adult patients, while skeletal ClassⅡhyperdivergent female adult patients have a risk of reduction in the oropharyngeal airway after maximuim anchorage retraction of the maxillary anterior teeth.

ObjectiveTo explore the regulation of hypothalamic-pituitary-gonadal （HPG） axis by modified Erxian decoction in rats with perimenopausal syndrome （PMS） and to further analyze the expression of proteins related to the silent information regulator 1 （SIRT1）/hypothalamic kisspeptin （Kisspeptin）/gonadotropin-releasing hormone （GnRH） signaling pathway in the arcuate nucleus region （ARC） of the hypothalamus， so as to reveal the potential target of action and molecular biological mechanism of modified Erxian decoction for the treatment of perimenopausal syndrome. MethodsAn animal model was established via the incomplete castration method， with successful modeling confirmed by the exfoliated cervical cell smear method. The 48 rats were divided into six groups based on the randomization principle after successful modeling， including a sham operation group， a model group， an estradiol valerate group （0.09 mg∙kg^-1∙d^-1）， high-， medium-， and low-dose modified Erxian decoction groups （7.614， 3.807，1.903 5 g∙kg^-1∙d^-1）， with 8 rats in each group. The estradiol valerate group and the high-， medium- and low-dose modified Erxian decoction groups were continuously administered by gavage for 28 days， and the indicators were detected 24 hours after the last administration. Body weights and uterine indices were measured. The pathological changes of the uterus were observed by hematoxylin-eosin （HE） staining. Enzyme-linked immunosorbent assay （ELISA） was performed to measure the levels of estradiol （E₂）， follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and gonadotropin-releasing hormone （GnRH）. Real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot were used to determine the expression levels of SIRT1， Kisspeptin， kisspeptin receptor （GPR54）， and GnRH in the ARC region of the hypothalamus and gonadotropin-releasing hormone receptor （GnRH-R） in pituitary. ResultsCompared with the sham operation group， rats in the model group had a significantly increased body weight （P0.01）， reduced wet weight and index of uterus （P0.01）， endometrial thinning or atrophy， glandular atrophy， and a decreasing number of glands. Additionally， serum levels of E₂ and the expression of SIRT1 in the ARC region of the hypothalamus significantly decreased （P0.01）. Serum levels of FSH， LH， and GnRH， the expression of Kisspeptin， GPR54， and GnRH in the ARC region of the hypothalamus， and GnRH-R in pituitary significantly increased （P0.01）. Compared with the model group， the estradiol valerate group and the high-， medium-dose modified Erxian decoction groups had significantly reduced body weight， serum levels of FSH， LH， and GnRH， and expression of Kisspeptin， GPR54， and GnRH in the ARC region of the hypothalamus and GnRH-R in pituitary （P0.05， P0.01） and significantly increased wet weight and index of uterus， serum level of E₂， and expression of SIRT1 in the ARC region of the hypothalamus （P0.05， P0.01）. In addition， they showed thickened endometrium， increased number of endometrial glands， and improved glandular atrophy. ConclusionModified Erxian decoction regulates the function of the HPG axis through multi-targets， and its mechanism of action may be related to the up-regulation of the expression of SIRT1 in the ARC region of the hypothalamus， the inhibition of the over-activation of the Kisspeptin/GnRH signaling pathway， the regulation of the expression of GnRH-R in the pituitary， the restoration of secretion balance of gonadotropins， and the elevation of the estrogen level. This study provides an experimental basis for the interpretation of the scientific connotation of modified Erxian decoction in the treatment of perimenopausal syndrome and a theoretical reference for the development of a novel therapeutic strategy based on the SIRT1/Kisspeptin/GnRH pathway.

Objective:To investigate the predictive value of controlling nutritional status (CONUT) score in the prognosis of patients with advanced diffuse large B-cell lymphoma (DLBCL).Methods:A retrospective case series study was performed. The clinical data of 654 patients newly diagnosed with advanced DLBCL diagnosed in 7 medical centers in Huaihai Lymphoma Working Group from October 2009 to January 2022 were retrospectively collected. All the patients received rituximab-based immune chemotherapy regimens. The patients were randomly assigned to the training set (458 cases) and the validation set (196 cases) in a 7:3 ratio. The clinicopathological data of patients were collected, and the CONUT score was calculated based on albumin, lymphocyte count, and total cholesterol. The optimal critical value of CONUT scote was determined by using MaxStat method. Kaplan-Meier method was used to draw survival curves; Cox proportional hazards model was used to make univariate analysis and multivariate analysis on the factors influencing overall survival (OS). The efficacy of CONUT score in combination with the International prognostic index (IPI) and an enhanced IPI (NCCN-IPI) in predicting OS was evaluated by using receiver operating characteristic (ROC) curves.Results:The median follow-up time of 654 patients was 38.1 months (95% CI: 35.3 months- 40.9 months), and the 5-year OS rate was 49.2%. According to the MaxStat method, the optimal critical value for CONUT score was determined to be 6 points. All the patients were classified into the normal nutritional status group (CONUT score ≤ 6 points, 489 cases) and the poor nutritional status group (CONUT score > 6 points, 165 cases). The results of the multivariate analysis showed that CONUT score > 6 points, male, lactate dehydrogenase >240 U/L, high white blood cell count, low hemoglobin level and age > 60 years were independent risk factors for OS of patients with advanced DLBCL (all P < 0.05). Patients in the poor nutritional status group (CONUT score > 6 points) had worse OS compared with that in the normal nutritional status group in the overall cohort of advanced DLBCL. Subgroup analysis revealed that among patients with Eastern Cooperative Oncology Group-performance status (ECOG PS) score < 2 points, IPI low-intermediate risk, IPI intermediate-high risk, NCCN-IPI low-intermediate risk, and NCCN-IPI intermediate-high risk, the patients in the poor nutritional status group (CONUT score > 6 points) had worse OS compared with that in the normal nutritional status group (CONUT score ≤ 6 points) (all P < 0.05). Conclusions:CONUT score has a certain value in the assessment of the prognosis of patients with advanced DLBCL, and its predictive efficacy is further improved when combined with IPI and NCCN-IPI.

Objective:To investigate the relationship between protein-energy wasting (PEW) and parathyroid hormone (PTH) levels in patients undergoing maintenance hemodialysis.Methods:A cross-sectional study was conducted to enroll 150 adult patients undergoing maintenance hemodialysis at The Third Affiliated Hospital of Anhui Medical University from January 2022 to May 2023. These patients were categorized into four groups based on their PTH levels: low PTH group (< 150 ng/L), standard PTH group (150-300 ng/L), very high PTH group (300-600 ng/L), and extreme high PTH group (> 600 ng/L). The diagnosis of PEW was determined using the diagnostic criteria proposed by the International Society of Renal Nutrition and Metabolism (ISRNM). Logistic regression analysis was performed to investigate the association between PEW and PTH levels.Results:Among the 150 patients undergoing maintenance dialysis, 52 (34.7%) were diagnosed with PEW. The prevalence of PEW was significantly higher in the low PTH group compared with the standard, very high, and extreme high PTH groups ( χ2 = 20.64, all P < 0.05). Univariate logistic regression analysis revealed a strong association between low PTH levels ( OR = 13.810, 95% CI: 2.907-65.603, P = 0.001) and an increased risk of PEW. The risk of PEW in the low PTH group was 13.810 times higher than that in the extreme high PTH group. Multivariate logistic regression analysis further confirmed that low PTH levels ( OR = 19.891, 95% CI: 1.810-218.620, P = 0.014) and low C-reactive protein levels ( OR = 1.056, 95% CI: 1.015-1.099, P = 0.007) were independently associated with an increased risk of PEW. Higher hemoglobin levels ( OR = 0.959, 95% CI: 0.931-0.988, P = 0.005) and a larger middle upper arm circumference ( OR = 0.544, 95% CI: 0.338-0.875, P = 0.012) were independently associated with a reduced risk of PEW. The risk of PEW in the low PTH group was 19.891 times higher than that in the extreme high PTH group. However, there was no significant difference in the risk of PEW in the standard and very high PTH groups compared with the extreme high PTH group (both P > 0.05). Conclusion:The risk of PEW is markedly elevated in patients with low PTH levels, emphasizing the importance of clinical attention to the prevention and treatment of low PTH levels. Addressing this issue may hold great value in reducing the risk of PEW.

Objective: To investigate the mechanism of action of Wuzi Yanzong pill (WYP) in rats with oligoasthenozoospermia (OAZ) via metabolomics and to provide a possible basis for improving this WYP-based treatment. Methods: A rat model of OAZ was established by treating male Sprague–Dawley rats with glucosides from Tripterygium wilfordii Hook. F. Seventy-two rats were randomly divided into six groups: control, L-carnitine (positive control), model, and low-, medium-, and high-dose WYP groups. Rats in the experimental groups were treated with WYP for 4 weeks. At the end of the treatment period, sperm cell quality (density, motility, and viability) was assessed using a semen analysis system, mitochondrial membrane potential (MMP) was assessed using flow cytometry, and testicular injury was assessed using hematoxylin and eosin staining to validate the therapeutic effect of WYP in OAZ. Further, serum metabolomics-based analysis was performed using high-performance liquid chromatography-mass spectrometry to identify differential metabolic pathways and possible mechanisms of action of WYP in OAZ treatment. Results: A rat model of OAZ was considered successfully-established after comparing the quality of spermatozoa in the model group to that in the control group. WYP-M and WYP-H treatments significantly improved sperm cell density, motility, and viability compared with those in the model group (all P < .05). Compared with the model group, both WYP-M and WYP-H treatments increased MMP values (P = .006 and P = .021 respectively), while there was no significant difference in the L-carnitine group. L-carnitine and WYP administration reversed damage to the testes to varying degrees compared with that in the model group. Further, 44 differential metabolites and four metabolic pathways, especially autophagy pathway, related to OAZ were identified via metabolomics. Conclusions WYP improves sperm cell quality and MMP in OAZ primarily via autophagy regulation. These findings can be employed to improve the efficacy of WYP in humans.

Glutamate is a major excitatory neurotransmitter in the central nervous system and a potential neurotoxin.During the development of depression,the glutamate concentration increases in the hippocampus.When glutamate accumulates,it causes serious damage to neurons and brain tissue,aggravating the depressive state.Therefore,glutamate accumulation may be a major mechanism of depression development.Astrocytes,glutamate transporters,and glutamate receptors play important regulatory roles in the glutamate concentration.This article reviews the mechanism-of-action of traditional Chinese medicine on depression by regulating astrocytes,glutamate transporters,and glutamate receptors,and provides new ideas to explore treatment of depression by traditional Chinese medicine.

Objective:To analyze the screening test results of people infected with human immunodeficiency virus (HIV) in the window period confirmed to be "negative" by Western blotting, with a view to finding a way to identify people infected with HIV during the window period as soon as possible.Methods:In the serum (plasma) samples of HIV-positive people screened by the fourth-generation chemiluminescent immunoassay in medical institutions at all levels in Pudong New District, Shanghai from 2014 to 2021, a total of 100 people (200 samples) were confirmed as "negative" and the fourth-generation enzyme-linked immunosorbent assay was screened positive. According to the follow-up results, it was divided into the early infection group (24 cases) and the uninfected group (76 people), and the fourth-generation rapid diagnostic test (RDT) was performed. The compliance rates of positive results of screening and follow-up were compared, and the epidemiological data of early HIV infections were analyzed. The chi-square test was used for statistical analysis.Results:Of the 200 samples, 48(24.00%) were early infected. A total of 106 samples antigens and (or) antibodies were positive by the fourth-generation RDT screening, and the compliance rate with the follow-up results was 45.28%(48/106), of which those of the fourth-generation RDT screening antigen positive and follow-up results were 100.00%(36/36), which was higher than the antibody positive results (24.68%(19/77)). The difference was statistically significant ( χ2=57.49, P<0.001). Of the 24 cases of early HIV infections, 19(79.2%) had acute symptoms. Only one out of six people≥50 years old had asked about the partner about his HIV status before engaging high-risk sex, and 13 out of 18 people <50 years old had asked the partners about their HIV status or to detect HIV before engaging high-risk sex. The difference was statistically significant ( χ2=5.71, P=0.017). Out of the six people ≥50 years old, only one actively tested HIV, and 12 out of 18 people <50 years old actively tested HIV, and the difference was statistically significant ( χ2=4.53, P=0.033). Conclusions:The Western blotting confirmed "negative" samples may be false negative. The comprehensive evaluation which combined with the fourth-generation screening test could help to screen out HIV window infection. In addition, the publicity, education and monitoring of high-risk population need to be further strengthened.
