OBJECTIVES:
To investigate the association between insulin resistance and uterine volume in girls with idiopathic central precocious puberty (ICPP).
METHODS:
A retrospective study was conducted involving 61 girls diagnosed with ICPP who visited the pediatric growth and development clinic of the Third Affiliated Hospital of Zhengzhou University between January 2022 and September 2024, designated as the ICPP group, and 61 normally developing girls as the control group. The differences in insulin resistance index (homeostasis model assessment of insulin resistance, HOMA-IR), uterine volume, and other indicators between the two groups were compared, and the relationship between insulin resistance and uterine volume in these girls was analyzed.
RESULTS:
The uterine volume and HOMA-IR level in the ICPP group were significantly higher than those in the control group (P<0.05). Correlation analysis revealed that there was a positive correlation between HOMA-IR level and uterine volume in the ICPP group (rs=0.643, P<0.001). Multiple linear regression analysis indicated that as HOMA-IR increased,uterine volume in the girls tended to increase (P<0.05).
CONCLUSIONS
There is an association between insulin resistance and uterine volume in girls with ICPP, and as HOMA-IR increases, uterine volume in the girls also increases.

Ursodeoxycholic acid (UDCA) is a naturally occurring, low-toxicity, and hydrophilic bile acid (BA) in the human body that is converted by intestinal flora using primary BA. Solute carrier family 7 member 11 (SLC7A11) functions to uptake extracellular cystine in exchange for glutamate, and is highly expressed in a variety of human cancers. Retroperitoneal liposarcoma (RLPS) refers to liposarcoma originating from the retroperitoneal area. Lipidomics analysis revealed that UDCA was one of the most significantly downregulated metabolites in sera of RLPS patients compared with healthy subjects. The augmentation of UDCA concentration (≥25 μg/mL) demonstrated a suppressive effect on the proliferation of liposarcoma cells. [15N2]-cystine and [13C5]-glutamine isotope tracing revealed that UDCA impairs cystine uptake and glutathione (GSH) synthesis. Mechanistically, UDCA binds to the cystine transporter SLC7A11 to inhibit cystine uptake and impair GSH de novo synthesis, leading to reactive oxygen species (ROS) accumulation and mitochondrial oxidative damage. Furthermore, UDCA can promote the anti-cancer effects of ferroptosis inducers (Erastin, RSL3), the murine double minute 2 (MDM2) inhibitors (Nutlin 3a, RG7112), cyclin dependent kinase 4 (CDK4) inhibitor (Abemaciclib), and glutaminase inhibitor (CB839). Together, UDCA functions as a cystine exchange factor that binds to SLC7A11 for antitumor activity, and SLC7A11 is not only a new transporter for BA but also a clinically applicable target for UDCA. More importantly, in combination with other antitumor chemotherapy or physiotherapy treatments, UDCA may provide effective and promising treatment strategies for RLPS or other types of tumors in a ROS-dependent manner.

ObjectiveTo investigate the significance of different non-treatment thresholds or upper limits of normal (ULN) of alanine aminotransferase (ALT) in evaluating significant liver pathological injury in patients with chronic hepatitis B virus (HBV) infection, and to provide guidance for clinical diagnosis and treatment. MethodsThis study was conducted among 733 patients with chronic HBV infection who were hospitalized in Ningbo No. 2 Hospital from January 2015 to December 2023 and underwent liver biopsy and histopathological examination, and all patients had a persistent ALT level of ≤40 U/L and positive HBV DNA (>30 IU/mL). According to the treatment threshold or ULN of ALT, the patients were divided into group 1 with 575 patients (≤35 U/L for male patients, ≤25 U/L for female patients), group 2 with 430 patients (≤30 U/L for male patients, ≤19 U/L for female patients), group 3 with 443 patients (≤27 U/L for male patients, ≤24 U/L for female patients), group 4 with 446 patients (≤25 U/L), group 5 with 158 patients (>35 U/L for male patients, >25 U/L for female patients), and group 6 with 145 patients (>30 — ≤35 U/L for male patients, >19 — ≤25 U/L for female patients). Groups 2, 5, and 6 were compared to analyze the severity of liver pathological injury in patients with different ALT levels and the constituent ratio of patients with significant liver pathological injury, and groups 1, 2, 3, and 4 were compared to investigate the value of different ULN or non-treatment thresholds of ALT in determining liver inflammation grade (G), liver fibrosis stage (S), and the treatment indication based on liver pathology. The independent-samples t test was used for comparison of normally distributed continuous data between two groups; a one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test or the Tambane’s test was used for further comparison between two groups; the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the Kruskal-Wallis H test was used for comparison between multiple groups and further comparison between two groups; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups; a Ridit analysis was used for comparison of ranked data. A multivariate Logistic regression analysis (forward stepwise) was performed with whether liver pathology met the treatment indication (≥G2 and/or ≥S2) as the dependent variable and related factors with a significant impact on the dependent variable (P <0.05) as the independent variable. The receiver operating characteristic (ROC) curve was plotted, and the area under the ROC curve (AUC), as well as sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio, was used to assess the diagnostic value of different non-treatment thresholds of ALT. ResultsAmong the 733 patients, 259 (35.33%) had ≥G2 liver inflammation, 211 (28.79%) had ≥S2 liver fibrosis, and 306 (41.75%) had treatment indication (≥G2 and/or ≥S2). There was a significant difference in liver inflammation grade (G0 — G4) between groups 2, 5, and 6 (χ2=22.869, P <0.001), and there were also significant differences in the constituent ratios of patients with ≥G2 or ≥G3 liver inflammation between the three groups (χ2=21.742 and 14.921, P<0.001 and P=0.001). There was a significant difference in liver fibrosis stage (S0 — S4) between groups 2, 5, and 6 (χ2=16.565, P<0.001), and there were also significant differences in the constituent ratios of patients with ≥S2, ≥S3 or S4 liver fibrosis between the three groups (χ2=13.264, 13.050, and 6.260, P=0.001, 0.001, and 0.044). There were significant differences between groups 2, 5, and 6 in the constituent ratios of patients with or without treatment indication based on liver pathology (χ2=20.728, P<0.001). There were significant differences between groups 2, 5, and 6 in the constituent ratio of male patients (χ2=24.836, P<0.05), age (F=5.710, P<0.05), ALT (F=473.193, P<0.05), aspartate aminotransferase (AST) (F=107.774, P<0.05), ALT/AST ratio (F=40.167, P<0.05), γ-glutamyl transpeptidase (GGT) (H=15.463, P<0.05), aspartate aminotransferase-to-platelet ratio index (APRI) (H=63.024, P<0.05), and LIF-5 (5 indicators for liver inflammation and fibrosis) (H=46.397, P<0.05). In groups 1 — 4, compared with the patients without treatment indication, the patients with treatment indication had a significantly lower constituent ratio of patients with positive HBeAg, significantly lower levels of platelet count (PLT) and HBV DNA, and significantly higher age, ALT, AST, GGT, APRI, FIB-4, and LIF-5 (all P<0.05). The Logistic regression analysis showed that age (odds ratio [OR]=1.044, 95% confidence interval [CI]: 1.025 — 1.063, P<0.001), GGT (OR=1.022, 95%CI: 1.007 — 1.038, P=0.003), and HBV DNA (OR=0.839, 95%CI: 0.765 — 0.919, P<0.001) were influencing factors for treatment indication based on liver pathology in group 1; HBeAg (OR=1.978, 95%CI: 1.269 — 3.082, P=0.003), age (OR=1.048, 95%CI: 1.025 — 1.071, P<0.001), GGT (OR=1.016, 95%CI: 1.001 — 1.031, P=0.041), and PLT (OR=0.995, 95%CI: 0.991 — 1.000, P=0.049) were influencing factors in group 2; age (OR=1.040, 95%CI: 1.014 — 1.066, P=0.002), ALT (OR=1.047, 95%CI: 1.005 — 1.092, P=0.029), HBV DNA (OR=0.817, 95%CI: 0.736 — 0.907, P<0.001), and LIF-5 (OR=7.382, 95%CI: 1.151 — 47.330, P=0.035) were influencing factors in group 3; age (OR=1.054, 95%CI: 1.031 — 1.077, P<0.001), ALT (OR=1.061, 95%CI: 1.016 — 1.107, P=0.008), and HBV DNA (OR=0.825, 95%CI: 0.743 — 0.917, P<0.001) were influencing factors in group 4. The diagnostic performance for identifying ≥G2 liver inflammation, ≥S2 liver fibrosis, and treatment indication in groups 1 — 4 had an AUC of >0.7; group 1 showed the lowest sensitivity (28.76%) and the highest specificity, positive predictive value, positive likelihood ratio, and negative likelihood ratio in judging treatment indication; group 2 had the highest sensitivity and negative predictive value and the lowest negative likelihood ratio; groups 3 and 4 had similar diagnostic indicators. ConclusionIn patients with chronic HBV infection and a persistently low ALT level, the severity of liver histopathological injury and the constituent ratio of significant liver histopathological injury decrease with the reduction in ALT level. A higher non-treatment threshold or ULN of ALT can help to identify the patients requiring treatment (with a higher specificity), while a lower non-treatment threshold or ULN of ALT can help to identify the patients who do not require treatment (with a higher sensitivity).

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Aim To explore the potential targets and mechanisms of Houpuwenzhongtang for the treatment of spleen and stomach deficiency cold stomach disease. Methods Firstly, TCMSP database, disease database and compound target prediction platform were used to collect active components, disease targets and predict potential targets. Secondly, Cytoscape 3.7.2 and String platform were used to screen key chemical components and core targets, and PPI network diagram was constructed. Finally, The active components with degree greater than 30 were used for molecular docking with key targets, and some docking results were selected for cell experiment. Results The key active components of Houpuwenzhongtang in the treatment of spleen and stomach deficiency cold stomach disease were hesperidin, magnolol, 6-gingerol, and so on. The key targets were JUN, AKT1, IL-8, etc.. The related pathways mainly involved immune response, signaling transduction, cell proliferation and apoptosis. Molecular docking results showed that the key active components had good binding activity with disease targets. The results of cell experiments showed that magnolol, hesperidin and 6-gingerol had different degrees of anti-inflammatory activity against IL-8 in a dose-dependent manner. Conclusions It is speculated that Houpuwenzhongtang may act on IL-8, JUN, AKT1 and other targets through magnolol, hesperidin,6-gingerol and other active ingredients, and participate in the regulation of PI3K-AKT signaling pathway, N F-K B signaling pathway for the treatment of spleen and stomach deficiency cold stomach disease. And it is found for the first time that 6-gingerol could stably bind to multiple disease targets related spleen and stomach deficiency cold stomach disease,such as AKT1,IL-8 and so on. The result suggests that 6-gingerol is worth further research. Through the results of IL-8 cell experiment, it is speculated that the components such as magnolol and hesperidin may play a role in gastric diseases caused by Helicobacter pylori infection by reducing the content of IL-8 in gastric mucosa.

Excessive application of chemical fertilizer has caused many problems in Angelica dahurica var. formosana planting, such as yield decline and quality degradation. In order to promote the green cultivation mode of A. dahurica var. formosana and explore rhizosphere fungus resources, the rhizosphere fungi with nitrogen fixation, phosphorus solubilization, potassium solubilization, iron-producing carrier, and IAA-producing properties were isolated and screened in the rhizosphere of A. dahurica var. formosana from the genuine and non-genuine areas, respectively. The strains were identified comprehensively in light of the morphological characteristics and ITS rDNA sequences, and the growth-promoting effect of the screened strains was verified by pot experiment. The results showed that 37 strains of growth-promoting fungi were isolated and screened from the rhizosphere of A. dahurica var. formosana, mostly belonging to Fusarium. The cultured rhizosphere growth-promoting fungi of A. dahurica var. formosana were more abundant and diverse in the genuine producing areas than in the non-genuine producing areas. Among all strains, Aspergillus niger ZJ-17 had the strongest growth promotion potential. Under the condition of no fertilization outdoors, ZJ-17 inoculation significantly promoted the growth, yield, and accumulation of effective components of A. dahurica var. formosana planted in the soil of genuine and non-genuine producing areas, with yield increases of 73.59% and 37.84%, respectively. To a certain extent, it alleviated the restriction without additional fertilization on the growth of A. dahurica var. formosana. Therefore, A. niger ZJ-17 has great application prospects in increasing yield and quality of A. dahurica var. formosana and reducing fertilizer application and can be actually applied in promoting the growth of A. dahurica var. formosana and producing biofertilizer.
