Diabetic kidney disease(DKD),a prevalent complication of diabetes mellitus,remains a leading cause of end-stage renal disease.Recent research has identified lipophagy,a novel mechanism in DKD pathogenesis,drawing increasing attention in the field.This paper explores the biological connotation of the"internal heat leading to Zheng"pathogenesis based on lipophagy.The study proposes that lipophagy represents the microscopic biological correlation of liver-spleen coordination in regulating spleen transport and the ascending-descending dynamics of the middle jiao.Under persistent hyperglycemia,the suppression of lipophagic activity mirrors the traditional Chinese medicine(TCM)pathophysiological process described as"excessive fire consuming healthy qi,"whereas aberrant lipid accumulation in the kidney corresponds to the dynamic aggregation and dispersion of micro-zhengjia.Lipotoxicity,a key driver of DKD progression,is interpreted as the biological manifestation of accumulated turbidity transforming into toxicity,resulting in progressive impairment of renal essence and function.The dynamic process of lipophagy dysfunction under hyperglycemia,marked by renal microangiopathy,glomerular and tubular dysfunction,and renal fibrosis,closely mirrors the pathological evolution of"micro-zhengjia"and"internal heat leading to Zheng."Consequently,TCM strategies for DKD prevention and treatment should emphasize heat regulation,stage-specific interventions,liver-spleen harmonization,metabolic modulation,early collateral protection,and blood-activating approaches.

Diabetic kidney disease (DKD) is a common microvascular complication of diabetes. "Internal heat leading to zheng" is the core pathogenesis of DKD, while "glucose toxicity" is transformed from subtle substances through "internal heat" and the cementation of various pathological products, which is pivotal to the transformation of diabetes to DKD. "Glucose toxicity" is characterized by deep and widespread heat, caused by various pathological factors, and its sticky nature makes it difficult to resolve, which can cause severe damage to the kidney collaterals. In the early stage of "glucose toxicity", it is yang pathogen, which can be transformed into yin pathogen in the later stage with disease progression. In clinical practice, treatment should be based on disease staging, with attention on grasping the pathogenesis of "internal heat leading to zheng" and identifying the nature of "glucose toxicity". During the diabetic period, clearing heat is the primary method, often using modified Yueju Pill and Dachaihu Decoction. In the early stage of DKD, treatment primarily focuses on clearing and penetrating latent heat to treat DKD, aiming to prevent toxic heat from transitioning from qi to blood. The approach emphasizes clearing heat and re-penetrating, detoxification, and re-clearing, often using a self-made modified Qingre Xiaozheng Decoction. In the middle and late stages of DKD, the focus shifts to clearing heat, eliminating zheng, strengthening vital qi, and dispelling turbidity, with commonly used treatments including the self-made modified Xiezhuo Xiaozheng Formula, Jingui Shenqi Pill, and Zhenwu Decoction.

OBJECTIVES:
This study aimed to compare the osteogenic performance differences of titanium surface coatings modified by dopamine or silanized graphene oxide, and to provide a more suitable modification scheme for titanium surface graphene oxide coatings.
METHODS:
Titanium was subjected to alkali-heat treatment and then modified with dopamine and silanization, respectively, followed by coating with graphene oxide. Control and experimental groups were designed as follows: pure titanium (Ti) group; titanium after alkali-heat treatment (Ti-NaOH) group; titanium after alkali-heat treatment and silanization modification (Ti-APTES) group; titanium after alkali-heat treatment and dopamine modification (Ti-DOPA) group; titanium with silanization-modified surface decorated with graphene oxide (Ti-APTES/GO) group; titanium with dopamine-modified surface decorated with graphene oxide (Ti-DOPA/GO) group. The physical and chemical properties of the material surfaces were analyzed using scanning electron microscopy (SEM), contact angle goniometer, X-ray photoelectron spectroscopy (XPS), and Raman spectrometer. The proliferation and adhesion morphology of mouse embryonic osteoblast precursor cells MC3T3-E1 on the material surfaces were observed by cell viability detection and immunofluorescence staining followed by laser confocal microscopy. The effects on the osteogenic differentiation of MC3T3-E1 cells were studied by alkaline phosphatase (ALP) staining, alizarin red staining and quantification, and real-time quantitative polymerase chain reaction.
RESULTS:
After modification with graphene oxide coating, a thin-film-like structure was observed on the surface under SEM. The hydrophilicity of all experimental groups was improved, among which the Ti-DOPA/GO group had the best hydrophilicity. XPS and Raman spectroscopy analysis showed that the modified materials exhibited typical D and G peaks, and XPS revealed the presence of a large number of oxygen-containing functional groups on the surface. CCK8 assay showed that all groups of materials had no cytotoxicity, and the proliferation level of the Ti-APTES/GO group was higher than that of the Ti-DOPA/GO group. Under the laser confocal microscope, the cells in the Ti-DOPA/GO and Ti-APTES/GO groups spread more fully. The Ti-DOPA/GO and Ti-APTES/GO groups had the deepest ALP staining, and the Ti-APTES/GO group had the most alizarin red-stained mineralized nodules and the highest quantitative result of alizarin red staining. In the Ti-DOPA/GO and Ti-APTES/GO groups, the expression of the early osteogenic-related gene RUNX2 reached a relatively high level, while in the expression of the late osteogenic-related genes OPN and OCN, the Ti-APTES/GO group performed better than the Ti-DOPA/GO group.
CONCLUSIONS
Ti-APTES/GO significantly outperformed Ti-DOPA/GO in promoting the adhesion, proliferation, and in vitro osteogenic differentiation of MC3T3-E1 cells.

OBJECTIVES:
To develop a risk prediction model for the transformation of chronic atrophic gastritis to high-grade intraepithelial neoplasia (HGIN) based on traditional Chinese medicine (TCM) syndrome patterns.
METHODS:
Clinical data of 201 chronic atrophic gastritis patients who visited the Second People's Hospital Affiliated to Fujian University of Traditional Chinese Medicine and Dong'erhuan Branch between January 2022 and March 2023 were retrospectively analyzed, including 32 patients with HGIN (HGIN group) and 169 patients with moderate and severe chronic atrophic gastritis (non-HGIN group). The information of demographic characteristics, dietary habits, lifestyle factors, social and psychosocial factors, family history of tumors, medical history and comorbidities, long-term medication, endoscopic findings, histopathological examination results, as well as TCM syndrome types were collected. Potential HGIN risk factors were screened using LASSO regression, and the significant risk factors for establishing an HGIN risk prediction model were identified using logistic regression analysis. The final model was visually presented using a nomogram, and its diagnostic performance was evaluated through receiver operating characteristic curve analysis.
RESULTS:
Spleen-stomach Qi deficiency was the most common TCM syndrome in both HGIN and non-HGIN groups. LASSO-logistic regression model analysis showed that heavy alcohol consumption (X1), syndrome of static blood in stomach collaterals (X2), low-grade intraepithelial neoplasia (X3), high-salt diet (X4), and age (X5) were independent risk factors related to the occurrence of HGIN, and the predictive model was ln[P/(1-P)]=2.159X1+2.230X2+1.664X3+2.070X4+0.122X5- 11.096. The model demonstrated good discriminative ability, calibration, and goodness-of-fit, with area under the curve values of 0.940 and 0.891 in the training and validation sets, respectively.
CONCLUSIONS
The TCM syndrome of static blood in stomach collaterals shows correlation with the transformation from chronic atrophic gastritis to HGIN. The HGIN prediction model based on TCM syndrome patterns developed in the study demonstrates potential value in clinical application.

Objective:To clarify the natural course of renal angiomyolipoma and the risk factors for its progression.Methods:This was a retrospective case-control study that included 401 patients diagnosed several times by ultrasound examination in the hospital physical examination system from January 2012 to June 2024. All patients were untreated. There were 128 male cases (31.90%) and 273 female cases (68.10%). The average age at initial diagnosis was (44.04 ± 10.24) years (range 22-78 years). The median longest diameter of the tumor at initial diagnosis was 9.0 (7.0, 11.5) mm. There were 359 cases (89.50%) with single tumors and 42 cases (10.50%) with multiple tumors. The patients were divided into the progression group(≥1 mm/year) and the non-progression group (<1 mm/year)based on the average growth rate of tumor. The differences in gender, age at initial diagnosis, initial tumor size, number of lesions and lesion site between the two groups were compared. Univariate logistic regression analysis was used to explore the relationship between the above factors and the progression of renal angiomyolipoma. Multivariate logistic regression analysis was conducted to identify the risk factors for progression.Results:A total of 401 cases were followed up for an average of (88.15 ± 21.09) months (range 48-140 months). The median maximum diameter of the tumors at the initial diagnosis was 9.0 (7.0, 11.5) mm, and at the end of the follow-up, it was 11 (8, 14) mm. The average growth rate was 0.38 mm/year, and the median growth rate was 0.25 (0, 0.60) mm/year. Among them, 341 cases (85.04%) were in the non-progression group with an average growth rate of 0.14 mm/year, and 60 cases (14.96%) were in the progression group with an average growth rate of 1.74 mm/year. The age of the progression group was lower than that of the non-progression group [(41.43 ± 9.64) years vs. (44.50±10.29) years], the initial maximum diameter of the tumors in the progression group was larger than that in the non-progression group [11.0 (8.0, 16.0) mm vs. 9.0 (7.0, 11.0) mm], and the proportion of multiple tumors in the progression group was higher than that in the non-progression group [14 cases (23.30%) vs. 28 cases (8.20%)], and the differences were all statistically significant ( P<0.05). Age at initial diagnosis( OR=0.96, 95% CI 0.93-0.99), initial tumor size ( OR=1.08, 95% CI 1.04-1.12) and number of lesions ( OR=2.96, 95% CI 1.38-6.34) were the risk factors for the growth of renal angiomyolipoma ( P<0.05), according to the results of multivariate logistic regression analysis. Conclusions:The natural history of most renal angiomyolipoma shows slow growth or relative quiescence, with a small number showing a significant increasing trend. Age at initial diagnosis, initial tumor size and number of lesions were independent risk factors for the growth of renal angiomyolipoma.
