ObjectiveTo evaluate the predictive value of six surrogate indices of insulin resistance (IR) for cardiovascular disease (CVD) risk in adults with cardiovascular-kidney-metabolic syndrome (CKM) stages 0-3. MethodsRelated data of 6 813 participants from the China health and retirement longitudinal study (CHARLS) were analyzed. Cox proportional hazards models and restricted cubic spline (RCS) analyses were performed to evaluate the associations between six insulin resistance surrogate indices (TyG, TyG-BMI, TyG-WC, TyG-WHtR, TyG-CVAI, CVAI) and CVD incidence. Predictive performance of 6 indices was comprehensively compared from 3 dimensionalities, using receiver operating characteristic (ROC) curves for discriminative ability, net reclassification improvement (NRI) for incremental predictive value, and decision curve analysis (DCA) for clinical utility. ResultsAll six IR surrogate indices significantly predicted CVD in the CKM population. RCS analysis revealed linear associations between each index and CVD incidence. ROC analysis showed that CVAI had the highest AUC (0.628,95%CI: 0.611-0.646), significantly outperforming the single TyG index (P=0.001 6). NRI analysis indicated significant reclassification improvement for the event group with CVAI (event NRI=0.042 8). DCA demonstrated that CVAI achieved the highest net benefit across most thresholds. Subgroup analysis confirmed stronger associations between CVAI and CVD risk in CKM stages 2-3. ConclusionsThese six IR surrogate indices serve as valuable tools for predicting CVD incidence in individuals with CKM stages 0-3. Among them, CVAI exhibits optimal predictive value for future CVD risk in adults with CKM stages 1-3.

To evaluate the reliability of flash continuous glucose monitoring(CGM) and itsaccuracy in supporting clinical decision-making after pancreatic surgery. This was a single-center retrospective secondary analysis derived from a multicenter prospective cohort study. Adult patients undergoing elective pancreatic surgery at Peking Union Medical College Hospital between March 2024 and March 2025 were enrolled. All patients had a CGM sensor placed on the left upper arm one day before surgery, with monitoring continued until at least postoperative day 7. The sensor measured interstitial fluid glucose every minute and allowed real-time scanning to obtain instant glucose values. In parallel, all patients underwent point-of-care(POC) blood glucose testing postoperatively. Paired glucose measurements at the same time points were identified using the Gplus glucose management system and the hospital information system. The mean absolute relative deviation(MARD) was calculated to assess the degree of deviation between the two methods. Agreement was evaluated using Bland-Altman analysis, and the clinical accuracy of CGM for decision support was assessed using Parkes error grid analysis. A total of 255 patients were ultimately included, with a median CGM wear time of 276.3(204.8, 314.1) hours. A total of 829 paired CGM and POC glucose values were obtained. The MARD between CGM values and POC glucose measurements was 14.10%. Bland-Altman analysis showed a mean difference of -18.72 mg/dL between the two methods, with 95% limits of agreement ranging from -69.88 to 32.44 mg/dL. The dispersion of differences widened progressively with increasing glucose levels, indicating marked heteroscedasticity. Parkes error grid analysis demonstrated that 99.88% of the paired glucose deviations fell within zones A and B, suggesting high accuracy of CGM in supporting correct clinical decisions. Flash CGM demonstrates generally satisfactory reliability for postoperative glucose monitoring following pancreatic surgery, with a low risk of harmful clinical decisions attributable to monitoring deviations. However, the measurement bias increases significantly with higher glucose levels, indicating that in the setting of severe hyperglycemia, CGM readings should be clinically calibrated and interpreted with caution in conjunction with POC blood glucose testing.

This study primarily investigates the effect of Liuwei Dihuang Pills on the activation and proliferation of female germline stem cells(FGSCs) in the ovaries and cortex of mice with premature ovarian failure(POF), and how it improves ovarian function. ICR mice were randomly divided into the control group, model group, Liuwei Dihuang Pills group, Liuwei Dihuang Pills double-dose group, and estradiol valerate group. A mouse model of POF was established by intraperitoneal injection of cyclophosphamide. After successful modeling, the mice were treated with Liuwei Dihuang Pills or estradiol valerate for 28 days. Vaginal smears were prepared to observe the estrous cycle and body weight. After the last administration, mice were sacrificed and sampled. Serum levels of estradiol(E_2), follicle-stimulating hormone(FSH), luteinizing hormone(LH), and anti-Müllerian hormone(AMH) were measured by enzyme-linked immunosorbent assay(ELISA). Hematoxylin-eosin(HE) staining was used to observe ovarian morphology and to count follicles at all stages to evaluate ovarian function. Immunohistochemistry was used to detect the expression of mouse vasa homolog(MVH), a marker of ovarian FGSCs. Immunofluorescence staining, using co-labeling of MVH and proliferating cell nuclear antigen(PCNA), was used to detect the expression and localization of specific markers of FGSCs. Western blot was employed to assess the protein expression of MVH, octamer-binding transcription factor 4(Oct4), and PCNA in the ovaries. The results showed that compared with the control group, the model group exhibited disordered estrous cycles, decreased ovarian index, increased atretic follicles, and a reduced number of follicles at all stages. FSH and LH levels were significantly elevated, while AMH and E_2 levels were significantly reduced, indicating the success of the model. After treatment with Liuwei Dihuang Pills or estradiol valerate, hormone levels improved, the number of atretic follicles decreased, and the number of follicles at all stages increased. MVH marker protein and PCNA proliferative protein expression in ovarian tissue also increased. These results suggest that Liuwei Dihuang Pills regulate estrous cycles and hormone disorders in POF mice, promote the proliferation of FGSCs, improve follicular development in POF mice, and enhance ovarian function.

Geniposidic acid(GA), a natural iridoid, exists in the roots, stems, leaves, flowers, bark, fruits, and seeds of medicinal plants of Rubiaceae, Eucommiaceae, and Plantaginaceae. Modern pharmacological studies have revealed that GA has multiple pharmacological activities, including organ-protective, anti-inflammatory, antioxidative, anti-osteoporosis, anti-neurodegenerative, and anti-cardiovascular effects. GA can enhance cell/organism defenses by upregulating key anti-inflammatory and antioxidant cytokines, while downregulating key node proteins in pro-inflammatory signaling pathways such as AhR and TLR4/MyD88, thereby exerting pharmacological effects such as organ protection. Pharmacokinetic investigations have suggested that after oral administration, GA can be distributed in multiple organs(kidney, liver, heart, spleen, lung, etc.). In addition, the pharmacokinetic behavior of GA could be significantly altered under disease conditions, as demonstrated by a marked increase in systematic exposure. This article comprehensively summarizes the reported pharmacological activities and mechanisms and systematically analyzes the pharmacokinetic characteristics and key parameters of GA, with the aim of providing a theoretical basis and scientific reference for the precise clinical application of GA-related Chinese patent medicines, as well as for the investigation and development of innovative drugs based on GA.

OBJECTIVE:
To retrospectively analyze the clinical data of newly diagnosed acute myeloid leukemia (AML) patients treated with venetoclax combined with azacitidine (Ven/Aza) or standard "3+7" regimen and similar regimens, collect real-world study data, compare the treatment response and adverse events between the two regimens, as well as perform survival analysis.
METHODS:
To retrospectively analyze the efficacy, survival, and adverse reactions of newly diagnosed AML patients treated with Ven/Aza (24 cases) and "3+7" regimens (117 cases ) in our hospital from September 2009 to March 2023, as well as factors influencing outcomes. A propensity score matching (PSM) was performed on age and Eastern Cooperative Oncology Group performance status (ECOG PS) to obtain a 1:1 matched cohort of 20 pairs, and the efficacy and survival before and after the matching were compared.
RESULTS:
The median age of patients in the Ven/Aza group was 69 years, while that in the "3+7" group was 56 years (P <0.001). Objective remission rate (ORR) was 62.5% in Ven/Aza group and 74.8% in "3+7" group (P >0.05). The median overall survival (OS) in the Ven/Aza group was 522 days, while that in the "3+7" group was 1 002 days (P >0.05). After controlling the two variables of age and ECOG PS, a PSM cohort of 20 pairs was obtained, in which the ORR was 65% in Ven/Aza group and 60% in "3+7" group (P >0.05). The median OS was 522 days and 629 days, and median progression-free survival (PFS) was 531 days and 198 days between the two groups, respectively. There were no statistically significant differences in OS and PFS between the two groups (both P >0.05). Additionally, the incidence of adverse events in the Ven/Aza group was significantly reduced.
CONCLUSION
The overall cohort shows that the "3+7" regimen has advantages in efficacy and survival, but Ven/Aza regimen is relatively safer. After performing PSM on age and ECOG PS, the Ven/Aza group showed improved efficacy, and a longer median PFS compared to "3+7" group.

Intentional tooth replantation (ITR) is an advanced treatment modality and the procedure of last resort for preserving teeth with inaccessible endodontic or resorptive lesions. ITR is defined as the deliberate extraction of a tooth; evaluation of the root surface, endodontic manipulation, and repair; and placement of the tooth back into its original socket. Case reports, case series, cohort studies, and randomized controlled trials have demonstrated the efficacy of ITR in the retention of natural teeth that are untreatable or difficult to manage with root canal treatment or endodontic microsurgery. However, variations in clinical protocols for ITR exist due to the empirical nature of the original protocols and rapid advancements in the field of oral biology and dental materials. This heterogeneity in protocols may cause confusion among dental practitioners; therefore, guidelines and considerations for ITR should be explicated. This expert consensus discusses the biological foundation of ITR, the available clinical protocols and current status of ITR in treating teeth with refractory apical periodontitis or anatomical aberration, and the main complications of this treatment, aiming to refine the clinical management of ITR in accordance with the progress of basic research and clinical studies; the findings suggest that ITR may become a more consistent evidence-based option in dental treatment.
