ObjectiveTo observe the effect of Zishen Tiaogan prescription on the oxidative stress injury in the rat model of diminished ovarian reserve (DOR) and explore the role of the Kelch-like ECH-associated protein 1 (Keap1)/nuclear factor E2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) signaling pathway. MethodsForty-eight female SD rats were randomly assigned into a normal group (n=12) and a modeling group (n=36). The rats in the modeling group received subcutaneous injection of galactose (350 mg·kg-1) combined with immobilization stress daily. After 28 days of modeling, 6 rats in the normal group and 6 rats in the modeling group were sacrificed to examine the modeling results. The successfully modeled rats were assigned into model, estradiol valerate (0.09 mg·kg-1), and low-, medium-, and high-dose (6.39, 12.78, 25.56 g·kg-1, respectively) Zishen Tiaogan prescription groups. The intervention lasted for 4 weeks with 6 animals per group. Hematoxylin-eosin staining was used to observe the estrous cycle and the pathological changes in the ovarian tissue. The ovarian index was calculated. Enzyme-linked immunosorbent assay was employed to measure the serum levels of sex hormones and oxidative stress-related indexes. Western blot and real-time PCR were employed to determine the protein and mRNA levels, respectively, of Nrf2, Keap1 and HO-1 in the ovarian tissue. The positive expression of superoxide dismutase 2 (SOD2) in the ovarian tissue was detected by immunohistochemistry (IHC). ResultsCompared with the normal group, the model group showed reduced follicles in the ovary, loose arrangement of the follicle granule layer, declined levels of anti-Mullerian hormone (AMH) and estradiol (E2) in the serum, elevated levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) (P<0.01), lowered levels of superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH) (P<0.01), and increased accumulation of malondialdehyde (MDA) (P<0.01). In addition, the modeling led to up-regulated protein and mRNA levels of Keap1 (P<0.01), the expression of Nrf2 and HO-1 protein was significantly decreased (P<0.01), the mRNA expression of Nrf2 was significantly decreased (P<0.05), the mRNA expression of HO-1 was significantly decreased (P<0.01), in the ovarian tissue. Compared with model group, the estradiol valerate and low-, medium-, and high-dose Zishen Tiaogan prescription groups showed increases in the ovarian index (P<0.01) and serum E2 and AMH levels (P<0.01), declined levels of FSH and LH (P<0.01), increased follicles in the ovary, elevated levels of SOD, CAT, and GSH, and reduced accumulation of MDA (P<0.05, P<0.01). Furthermore, these groups showcased down-regulated protein and mRNA levels of Keap1 (P<0.01), the expression of Nrf2 protein was significantly increased (P<0.01), the expression level of HO-1 protein was increased (P<0.05,P<0.01), and increased positive expression of SOD2 (P<0.01). ConclusionZishen Tiaogan prescription can regulate the serum levels of hormones, down-regulate the expression of Keap1, up-regulate the expression of Nrf2, HO-1, and SOD2, enhance the antioxidant capacity, and reduce the peroxidation damage in the ovarian tissue to improve the ovarian reserve function in the rat model of DOR. High-dose Zishen Tiaogan prescription demonstrated the best effect and the mechanism is associated with the regulation of the Keap1/Nrf2/HO-1 pathway.

Immunoglobulin A (IgA) nephropathy is a globally prevalent type of primary glomerulonephritis, characterized by complex symptoms and diverse clinical manifestations. The internationally recognized " multiple hit hypothesis" explains the systemic immune disease features of IgA nephropathy. However, current treatment strategies primarily focus on local pathological changes, inadequately addressing its complex systemic mechanisms. The " qi cycle in round" theory, an integral concept of the academic thought of HUANG Yuanyu, a prominent medical expert from the Qing Dynasty, offers a concise and insightful framework for understanding complex pathologies. For example, this theory provides valuable insights for elucidating the pathogenesis of IgA nephropathy and guiding its clinical management by simplifying intricate systemic processes. This study applies the " qi cycle in round" theory to postulate that patients with IgA nephropathy experience disrupted qi flow owing to spleen-stomach qi deficiency and dampness-heat accumulation. These imbalances manifest as internal symptoms, such as diarrhea; external vulnerability to illness; upper body symptoms, like sore throat; and lower body symptoms, such as hematuria and proteinuria. Pathologically, the condition is characterized by immune complex deposition. This article also emphasizes strategies that prioritize tonifying spleen-stomach qi to enhance the pivotal functions of transportation and transformation. Regulating qi and relieving stagnation are emphasized to harmonize ascending and descending dynamics. Additionally, eliminating turbidity and unblocking collaterals are highlighted to promote qi transformation. These approaches aim to restore the harmonious operation of organ qi dynamics and harmonious qi transformation functions. This study aims to provide a reference for syndrome differentiation and IgA nephropathy treatment using traditional Chinese medicine based on the " qi cycle in round" theory.

OBJECTIVE To establish drug utilization evaluation (DUE) criteria for pyrotinib to promote its appropriate application in clinical practice. METHODS Based on the label of Pyrotinib maleate tablets, with relevant guiding principles and diagnostic and treatment guidelines as the evaluation basis, DUE criteria for pyrotinib were determined through the Delphi method. Attribute hierarchical model (AHM) and entropy weight method (EWM) were used to combine and assign weights to each indicator within the DUE criteria. Additionally, the weighted technique for order preference by similarity to an ideal solution (TOPSIS) method was applied to perform rationality evaluation of medication in archived medical records from Hainan Provincial Tumor Hospital and Hainan Western Central Hospital regarding the use of pyrotinib from November 2019 to November 2023. RESULTS The established DUE criteria for pyrotinib included 4 primary indicators (prescription authority, indications for use, medication process, and medication outcomes) and 11 secondary indicators. The secondary indicators with higher weights were the route of administration and dosage (0.257) and indications in the label (0.241). Among the 88 archived cases included, there were 28 cases of inappropriate medication (31.82%), 43 cases of generally appropriate medication (48.86%), and 17 cases of appropriate medication (19.32%). The main issues related to inappropriate medication involved off-label use (42.05%) and inappropriate routes of administration and dosage (43.18%). CONCLUSIONS DUE criteria for pyrotinib established using the AHM-EWM-weighted TOPSIS method is highly operational and results in quantifiable evaluation outcomes. The overall rationality of the use of pyrotinib in the above hospitals remains to be improved, and there are some issues, like the off-label use,and inappropriate routes of administration and dosage being liaoyylyy@163.com unreasonable.

ObjectiveTo evaluate pharmacological effects of Shengmai injection(SMI)on cerebral ischemia and study its neuroprotective mechanism. MethodsMale specific pathogen-free (SPF) Sprague-Dawley (SD) rats were randomly divided into a sham group, a model group, a low-dose SMI group(3 mL·kg-1), a middle-dose SMI group(6 mL·kg-1), a high-dose SMI group(12 mL·kg-1), and a Ginaton group(4 mL·kg-1)according to the random number table method, with 12 rats in each group. The rat model of cerebral ischemia-reperfusion(MCAO/R)was prepared via the suture method. The administration groups were intraperitoneally injected with corresponding concentrations of SMI or Ginaton injection after reperfusion, which was conducted for 3 consecutive days. The sham group and model group were administered the equivalent volume of physiological saline. The pharmacological effects of SMI on brain injury in MCAO/R rats were evaluated by neurological function scores, cerebral infarction area, hematoxylin-eosin (HE) staining, Nissl staining, terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) staining, and Western blot. The dominant link and key protein of SMI treating cerebral injury were explored using proteomic analysis. The related mechanisms of SMI were further validated using enzyme-linked immunosorbent assay (ELISA), Western blot, and chloride ion fluorescence probe with oxygen-glucose deprivation/reoxygenation(OGD/R)-treated PC12 cells and MCAO/R rats. ResultsCompared with the sham group, the model group showed significantly increased neurological function scores, cerebral infarction area, neuronal apoptosis rate, and expression levels of apoptosis related proteins (P<0.05, P<0.01)and significantly decreased density of Nissl bodies and neurons(P<0.01). Compared with the model group, the SMI groups exhibited significantly decreased neurological function scores, cerebral infarction area, neuronal apoptosis rate, and expression levels of apoptosis related proteins (P<0.05, P<0.01)and significantly increased density of Nissl bodies and neurons (P<0.05). The proteomic analysis results showed that oxidative stress and inflammatory response were important processes of SMI intervening in MCAO/R injury, and the chloride intracellular channel protein 1 (CLIC1) was one of key proteins in its action network. The levels of representative indicators of oxidative stress and inflammatory response in the MCAO/R rats of the SMI groups were significantly reduced, compared with those in the model group(P<0.05, P<0.01), and the expression levels of CLIC1 and downstream NOD-like receptor protein 3 (NLRP3) decreased (P<0.01). In addition, the experimental results based on the OGD/R PC12 cells showed that SMI significantly increased the cell survival rate(P<0.01) and significantly decreased the intracellular chloride ion concentration(P<0.05). ConclusionSMI has neuroprotective effects. Oxidative stress and inflammatory response are key processes of SMI intervening in MCAO/R injury. The potential mechanism is closely related to the regulation of CLIC1.

Objective:
To investigate the correlation between social jetlag and psychological behavior in upper primary school students,so as to provide reference for sleep health promotion in primary school students.
Methods:
From April to June 2024, a survey was conducted among 4 341 fourth and fifth grade students from 9 public primary schools in a district in Beijing. Sleep patterns were assessed using a self designed questionnaire, while psychological behavior was evaluated using the Strengths and Difficulties Questionnaire (SDQ)(parent version). A generalized estimating equation (GEE) model was used to examine the association between different levels of social jetlag and psychological behavior problem scores in primary school students.
Results:
The proportions of students with social jetlag of <1.0, 1.0-<2.0, and ≥2.0 h were 57.6%, 30.6%, and 11.8%, respectively. The GEE model analysis found that after adjusting for covariates, compared with primary school students with social jetlag of <1.0 h, those with 1.0 -<2.0 and ≥2.0 h had higher scores for internalizing behavior problems [ β (95% CI ) =0.23(0.05-0.41),0.28(0.02-0.54), P < 0.01]. Primary school students with ≥2.0 h of social jetlag had higher scores for externalizing behavior problems [ β (95% CI )=0.42 (0.13-0.71), P <0.01]. Among boys and primary school students with an average nighttime sleep duration of ≥9 h, comparied with social jetlag of <1.0 h,those with sucial jetlag 1.0-<2.0 h had higher scores on internalizing and externalizing behavior problems[ β (95% CI )=0.32(0.07-0.56),0.51 (0.11-0.90), 0.26 (0.06-0.46),0.58 (0.25-0.91), P <0.05].
Conclusions
Greater social jetlag may be a risk factor for internalizing and externalizing behavior problems in upper primary school students. Reducing social jetlag may help decrease the occurrence of psychological behavior problems in primary school students.

Chinese medicinal materials serve as the material foundation of traditional Chinese medicine (TCM) culture. The sustainable development of Chinese medicinal material resources is a focal point in the modernization of TCM. With the increasing scarcity of Chinese medicinal material resources, the expansion of new Chinese medicinal material resources has become a crucial means for the sustainable utilization of these resources. New Chinese medicinal material resources refer to natural resources that have been newly discovered or developed, possessing potential medicinal value or healthcare functions, which fall outside the traditional application scope of herbal medicines. These resources have not yet been widely recognized or applied within the framework of traditional TCM theory. They specifically include artificial substitutes for endangered medicinal materials, new medicinal parts of medicinal plants, medicinal materials with expanded clinical applications, and foreign medicinal resources. The rational compatability and formulation of new Chinese medicinal material resources are essential pathways for integrating them into the TCM system. Due to the weak foundational research on new Chinese medicinal material resources in China, the characteristics of these resources that align with the TCM theory are not yet fully understood, posing numerous constraints on formulating prescriptions based on the traditional compatibility principles of TCM. This paper integrates the traditional formulation theory of TCM with modern data integration methods, proposing four formulation models for new TCM resources: synergistic compatibility, substitutive compatibility, symptom-based compatibility, and efficacy semantic compatibility. These models provide new insights for the application of new Chinese medicinal material resources, not only facilitating their rational use in clinical practice but also offering theoretical support for the development and compatibility research of these resources.

Objective:
This study explored whether anxiety and core self-evaluation mediate the relationship between negative life events and depressive symptoms in adolescents of the Yi ethnic minority in China.
Methods:
In this cross-sectional study, a convenience sample of 627 Yi adolescents 10–19 years old (252 males, 40.2%) from primary, middle and high schools in Liangshan Prefecture in China completed the Adolescent Self-Rating Life Events Checklist (ASLEC) to report on negative life events, the Second Edition of the Beck Depression Inventory (BDI-II) to report on depressive symptoms, the Core Self-Evaluations Scale (CSES) to describe core self-evaluation, and the Screen for Child Anxiety-Related Emotional Disorders (SCARED) to report anxiety symptoms.
Results:
In Pearson correlation analysis, total score and dimension subscores on the ASLEC correlated positively with total score and dimension subscores on the SCARED survey as well as with total score on the BDI. Total ASLEC score and dimension subscores correlated negatively with total CSES score. Mediation analysis indicated that negative life events affected depressive symptoms directly, as well as indirectly via core self-evaluation (mediating effect was 0.087; 95% confidence interval [CI], 0.063–0.113; p<0.001). The chain-mediated pathway effect was significant (mediating effect was 0.017; 95% CI, 0.011–0.026; p<0.001).
Conclusion
Yi adolescents in Liangshan Prefecture show certain prevalence of anxiety and depression, and they score relatively low on core self-evaluation. In this ethnic group, negative life events can affect depressive symptoms directly as well as indirectly through chain-mediated effects of anxiety and core self-evaluation.

Diabetes & Metabolism Journal 2025;49(1):128-143
Background:
The genetic basis for hyperglycaemia in pregnancy remain unclear. This study aimed to uncover the genetic determinants of gestational diabetes mellitus (GDM) and investigate their applications.
Methods:
We performed a meta-analysis of genome-wide association studies (GWAS) for GDM in Chinese women (464 cases and 1,217 controls), followed by de novo replications in an independent Chinese cohort (564 cases and 572 controls) and in silico replication in European (12,332 cases and 131,109 controls) and multi-ethnic populations (5,485 cases and 347,856 controls). A polygenic risk score (PRS) was derived based on the identified variants.
Results:
Using the genome-wide scan and candidate gene approaches, we identified four susceptibility loci for GDM. These included three previously reported loci for GDM and type 2 diabetes mellitus (T2DM) at MTNR1B (rs7945617, odds ratio [OR], 1.64; 95% confidence interval [CI],1.38 to 1.96]), CDKAL1 (rs7754840, OR, 1.33; 95% CI, 1.13 to 1.58), and INS-IGF2-KCNQ1 (rs2237897, OR, 1.48; 95% CI, 1.23 to 1.79), as well as a novel genome-wide significant locus near TBR1-SLC4A10 (rs117781972, OR, 2.05; 95% CI, 1.61 to 2.62; Pmeta=7.6×10-9), which has not been previously reported in GWAS for T2DM or glycaemic traits. Moreover, we found that women with a high PRS (top quintile) had over threefold (95% CI, 2.30 to 4.09; Pmeta=3.1×10-14) and 71% (95% CI, 1.08 to 2.71; P=0.0220) higher risk for GDM and abnormal glucose tolerance post-pregnancy, respectively, compared to other individuals.
Conclusion
Our results indicate that the genetic architecture of glucose metabolism exhibits both similarities and differences between the pregnant and non-pregnant states. Integrating genetic information can facilitate identification of pregnant women at a higher risk of developing GDM or later diabetes.
