ObjectiveTo analyze the distribution characteristics of traditional Chinese medicine (TCM) syndrome elements in different risk populations of heart failure complicated with type 2 diabetes. MethodsClinical data of 675 type 2 diabetes patients were retrospectively collected. Lasso-multivariate Logistic regression was used to construct a clinical prediction nomogram model. Based on this, 441 non-heart failure patients were divided into a low-risk group (325 cases) and a high-risk group (116 cases) according to the median risk score of heart failure complicated with type 2 diabetes. TCM diagnostic information (four diagnostic methods) was collected for both groups, and factor analysis was applied to summarize the distribution of TCM syndrome elements in different risk populations. ResultsLasso-multivariate Logistic regression analysis identified age, disease duration, coronary heart disease, old myocardial infarction, arrhythmia, absolute neutrophil count, activated partial thromboplastin time, and α-hydroxybutyrate dehydrogenase as independent risk factors for heart failure complicated with type 2 diabetes. These were used as final predictive factors to construct the nomogram model. Model validation results showed that the area under the curve (AUC) of the receiver operating characteristic (ROC) curve for the modeling group and validation group were 0.934 and 0.935, respectively. The Hosmer-Lemeshow test (modeling group P = 0.996, validation group P = 0.121) indicated good model discrimination. Decision curve analysis showed that the curves for All and None crossed in the upper right corner, indicating high clinical utility. The low-risk and high-risk groups each obtained 14 common factors. Preliminary analysis revealed that the main disease elements in the low-risk group were qi deficiency (175 cases, 53.85%), dampness (118 cases, 36.31%), and heat (118 cases, 36.31%), with the primary locations in the spleen (125 cases, 38.46%) and lungs (99 cases, 30.46%). In the high-risk group, the main disease elements were yang deficiency (73 cases, 62.93%), blood stasis (68 cases, 58.62%), and heat (49 cases, 42.24%), with the primary locations in the kidney (84 cases, 72.41%) and heart (70 cases, 60.34%). ConclusionThe overall disease characteristics in different risk populations of type 2 diabetes patients with heart failure are a combination of deficiency and excess, with deficiency being predominant. Deficiency and heat are present throughout. The low-risk population mainly shows qi deficiency with dampness and heat, related to the spleen and lungs. The high-risk population shows yang deficiency with blood stasis and heat, related to the kidneys and heart.

Cancer is characterized by abnormal cell proliferation. Cyclins and cyclin-dependent kinases (CDKs) have been recognized as essential regulators of the intricate cell cycle, orchestrating DNA replication and transcription, RNA splicing, and protein synthesis. Dysregulation of the CDK pathway is prevalent in the development and progression of human cancers, rendering cyclins and CDKs attractive therapeutic targets. Several CDK4/6 inhibitors have demonstrated promising anti-cancer efficacy and have been successfully translated into clinical use, fueling the development of CDK-targeted therapies. With this enthusiasm for finding novel CDK-targeting anti-cancer agents, there have also been exciting advances in the field of targeted protein degradation through innovative strategies, such as using proteolysis-targeting chimera, heat shock protein 90 (HSP90)-mediated targeting chimera, hydrophobic tag-based protein degradation, and molecular glue. With a focus on the translational potential of cyclin- and CDK-targeting strategies in cancer, this review presents the fundamental roles of cyclins and CDKs in cancer. Furthermore, it summarizes current strategies for the proteasome-dependent targeted degradation of cyclins and CDKs, detailing the underlying mechanisms of action for each approach. A comprehensive overview of the structure and activity of existing CDK degraders is also provided. By examining the structure‒activity relationships, target profiles, and biological effects of reported cyclin/CDK degraders, this review provides a valuable reference for both CDK pathway-targeted biomedical research and cancer therapeutics.

Bone repair remains an important target in tissue engineering, making the development of bioactive scaffolds for effective bone defect repair a critical objective. In this study, β-tricalcium phosphate (β-TCP) scaffolds incorporated with processed pyritum decoction (PPD) were fabricated using three-dimensional (3D) printing-assisted freeze-casting. The produced composite scaffolds were evaluated for their mechanical strength, physicochemical properties, biocompatibility, in vitro pro-angiogenic activity, and in vivo efficacy in repairing rabbit femoral defects. They not only demonstrated excellent physicochemical properties, enhanced mechanical strength, and good biosafety but also significantly promoted the proliferation, migration, and aggregation of pro-angiogenic human umbilical vein endothelial cells (HUVECs). In vivo studies revealed that all scaffold groups facilitated osteogenesis at the bone defect site, with the β-TCP scaffolds loaded with PPD markedly enhancing the expression of neurogenic locus Notch homolog protein 1 (Notch1), vascular endothelial growth factor (VEGF), bone morphogenetic protein-2 (BMP-2), and osteopontin (OPN). Overall, the scaffolds developed in this study exhibited strong angiogenic and osteogenic capabilities both in vitro and in vivo. The incorporation of PPD notably promoted the angiogenic-osteogenic coupling, thereby accelerating bone repair, which suggests that PPD is a promising material for bone repair and that the PPD/β-TCP scaffolds hold great potential as a bone graft alternative.

Originating but free from chromosomal DNA, extrachromosomal circular DNAs (eccDNAs) are organized in circular form and have long been found in unicellular and multicellular eukaryotes. Their biogenesis and function are poorly understood as they are characterized by sequence homology with linear DNA, for which few detection methods are available. Recent advances in high-throughput sequencing technologies have revealed that eccDNAs play crucial roles in tumor formation, evolution, and drug resistance as well as aging, genomic diversity, and other biological processes, bringing it back to the research hotspot. Several mechanisms of eccDNA formation have been proposed, including the breakage-fusion-bridge (BFB) and translocation-deletion-amplification models. Gynecologic tumors and disorders of embryonic and fetal development are major threats to human reproductive health. The roles of eccDNAs in these pathological processes have been partially elucidated since the first discovery of eccDNA in pig sperm and the double minutes in ovarian cancer ascites. The present review summarized the research history, biogenesis, and currently available detection and analytical methods for eccDNAs and clarified their functions in gynecologic tumors and reproduction. We also proposed the application of eccDNAs as drug targets and liquid biopsy markers for prenatal diagnosis and the early detection, prognosis, and treatment of gynecologic tumors. This review lays theoretical foundations for future investigations into the complex regulatory networks of eccDNAs in vital physiological and pathological processes.

Objective To identify the influencing factors of operation time of hand-assisted laparoscopic living donor nephrectomy, and to analyze the relationship between influencing factors and the severity of postoperative complications. Methods Clinical data of 91 donors who underwent hand-assisted laparoscopic nephrectomy were retrospectively analyzed. The correlation between preoperative baseline data of donors and operation time was analyzed. The relationship between operation time and postoperative complications was assessed and the threshold of operation time was determined. Results Multiple donor renal arteries, thick perirenal and posterior renal fat, metabolic syndrome, high Mayo adhesive probability (MAP) score and Clavien-Dindo score prolonged the operation time. By analyzing the receiver operating characteristic (ROC) curve, we found that when the operation time was ≥138 min, the incidence of postoperative complications of donors was significantly increased (P<0.05). Conclusions For donors with multiple renal arteries, thick perirenal and posterior renal fat, metabolic syndrome and high MAP score and Clavien-Dindo score, experienced surgeons should be selected to make adequate preoperative preparation and pay close attention after surgery, so as to timely detect postoperative complications and reduce the severity of complications, enhance clinical prognosis of the donors.

ObjectiveTo observe the clinical efficacy and relative mechanism of the Modified Wenshen Yixin Formula (温肾益心方加减, MWYF) as an auxiliary treatment of coronary heart disease (CHD) complicated with hypothyroidism of spleen-kidney yang deficiency. MethodsA total of 135 CHD patients complicated with hypothyroidism and spleen-kidney yang deficiency were included and divided into control group (67 cases) and experimental group (68 cases) according to the patients' wishes of herbal medicine administration. The control group was given conventional western medicine, while the treatment group was additionally given MWYF, 1 dose per day; both groups were treated for 8 weeks. The traditional Chinese medicine (TCM) syndrome scores, angina scores, SF-36 scores, thyroid function indicators including thyroid stimulating hormone (TSH), thyroxine (T4) and triiodothyronine (T3), as well as serum cyclic adenosine monophosphate (cAMP), cyclic guanosine monophosphate (cGMP), monocyte chemoattractant ligand 2 (CCL2), and tumor necrosis factor-related activator protein (CD40L) levels before and after treatment were compared between the two groups. The dosage and reduction and discontinuation rate of thyroid hormone preparations after treatment were compared between the two groups. The effectiveness regarding TCM syndrome and angina pectoris was evaluated, and the safety was assessed. ResultsBias was adjusted by matching on propensity score, and 102 cases were finally included in the statistical analysis, with 51 cases in each group. The total effective rate regarding TCM syndrome [94.12% (48/51) versus 64.71% (33/51)], the total effective rate regarding angina pectoris [80.39% (41/51) versus 62.75% (32/51)], and the reduction and discontinuation rate of thyroid hormone preparation [39.21% (20/51) versus 5.88% (3/51)] were significantly higher in the experimental group than those in the control group (P<0.05 or P<0.01). After treatment, the total TCM syndrome score, individual scores of major symptoms , the major symptoms score, the secondary symptoms score, angina pectoris score, and TSH level were significantly reduced (P<0.01), while all dimensions of SF-36 scores, T4, T3, and cAMP levels significantly increased in both groups (P<0.05 or P<0.01). The dosage of thyroid hormone preparations and the levels of cGMP, CCL2, and CD40L in the experimental group significantly decreased after treatment (P<0.01). When compared between the two groups after treatment, the total TCM syndrome score, the major symptoms score, the scores of individual major symptom (chest tightness, chest pain, fear of cold, cold limbs, waist and kness soreness and weakness), the secondary symptoms score, angina pectoris score, TSH, cGMP, CCL2, and CD40L levels of the experimental group were significantly lower than those of the control group (P<0.05 or P<0.01), while all dimension scores of SF-36, T4, T3, and cAMP levels were significantly higher (P<0.01). A total of three adverse events occurred during treatment, none of which were judged to be related to the interventions of this study. ConclusionMWYF can significantly ameliorate the TCM syndrome, angina pectoris, quality of life and thyroid function in CHD patients complicated with hypothyroidism and spleen-kidney yang deficiency, and can promote the reduction and disconti-nuation of thyroid hormone preparations. The mechanism may be related to the regulation of cAMP/cGMP balance, the regulation of hypothalamic-pituitary-thyroid metabolic axis and the reduction of immune inflammation.

OBJECTIVE:
To explore the effectiveness of Nice knot technique for wound closure in Gustilo type ⅢA and ⅢB open tibial fractures.
METHODS:
A retrospective study was performed on 22 patients with Gustilo type ⅢA and ⅢB open tibial fractures, who underwent wound closure using the Nice knot technique and were admitted between June 2021 and June 2022. There were 15 males and 7 females. The age ranged from 18 to 67 years, with an average of 41.9 years. The causes of injury included traffic accident in 11 cases, falling from height in 7 cases, and heavy object injuries in 4 cases. Fractures were located on the left side in 9 cases and on the right side in 13 cases. And 9 cases were type ⅢA fractures and 13 were type ⅢB fractures according to Gustilo classification. All patients had extensive soft tissue injuries, and no vascular or neurological damage was observed. The time from injury to debridement was 3-8 hours (mean, 6.5 hours). The sizes of wounds before operation and at 2 weeks after operation were measured and wound healing rate at 2 weeks after operation were calculated. The wound healing time and wound healing grading were recorded. The Vancouver Scar Scale (VSS) score was used to assess the wound scar after wound healed and the excellent and good rate was calculated.
RESULTS:
The wound area was 21.0-180.0 cm 2 (mean, 57.82 cm 2) before operation, and it was 1.2-27.0 cm 2 (mean, 6.57 cm 2) at 2 weeks after operation. The wound healing rate at 2 weeks after operation was 76%-98% (mean, 88.6%). After operation, 2 cases needed to adjust Nice knot due to skin cutting and 1 case occurred soft tissue infection on the wound. The other patient's wounds healed. The average wound healing time was 27.8 days (range, 18-44 days). And the wound healing were grade A in 13 cases and grade B in 9 cases. VSS score was 2-9, with an average of 4.1; 10 cases were rated as excellent, 10 as good, and 2 as poor, with an excellent and good rate of 90.9%. All patients were followed up 9-24 months (mean, 14.6 months). During follow-up, no deep infection or osteomyelitis occurred. Two cases experienced fracture non-union, and were treated with compression fixation and bone grafting. The fractures of the other patients all healed, with a healing time of 85-190 days (mean, 148.2 days).
CONCLUSION
Nice knot technique can be used in wound closure of Gustilo type ⅢA and ⅢB open tibial fractures effectively, which is easy to operate.

Primary aldosteronism (PA) mainly includes aldosteronoma (APA) and idiopathic aldosteronism (IHA). APA often presents as unilateral adrenal nodules, but can also be accompanied by non-functional adrenal nodules, which leads to difficulty of the identification. In this paper, the clinical characteristics, diagnosis and treatment process of two cases of PA with non-functional adrenal nodules were analyzed and discussed to provide some references for the accurate diagnosis and treatment of PA.
