Protein-protein interactions (PPIs) are not only crucial for the assembly of protein complexes but also fundamental for maintaining normal biological functions. These interactions are vital for protein structure and biological functionality and play a central role in cellular signaling, metabolic pathways, and regulatory networks. The 14-3-3 protein, highly conserved and widely expressed in eukaryotes, primarily recognizes and binds to its partner proteins to participate in essential life processes such as cell cycle control, signal transduction, and energy metabolism. This review discusses the role of dysregulated PPIs between 14-3-3 proteins and their partner proteins such as estrogen receptor α (estrogen receptor α, ERα), RAF proto-oncogene serine/threonine-protein kinase (C-RAF/RAF-1), and p53 in the onset and progression of tumors, focusing on the research progress of 14-3-3/ERα, 14-3-3/C-RAF, and 14-3-3/p53 molecular glues. These molecular glues, by mimicking or enhancing the phosphorylation sites of serine on partner proteins, form covalent bonds, salt bridges, and hydrogen bonds with 14-3-3 proteins, thereby enhancing the stability of PPIs and effectively intervening in protein activity and signaling under pathological conditions. Additionally, this article explores the potential of this chemical intervention strategy in clinically suppressing tumor progression, providing a theoretical foundation and practical guidance for future research directions.

OBJECTIVETo explore the relationship between angiotensin converting enzyme (ACE) gene single nucleotide polymorphisms (SNP) and premature coronary heart disease (PCHD) patients with blood stasis syndrome (BSS).

METHODSrs4343, rs4293, and rs4267385 were selected at SNP from ACE gene. Allele and genotype were detected. Frequencies of allele and genotype were compared by using time-of-flight mass spectrometry technique (TOF-MS).

RESULTSCompared with the healthy control group, genotype of rs4293 and rs4267385 in ACE gene were similar, but there was statistical difference in polymorphisms and allele frequencies of rs4343 in the I and II group (P < 0.05, P < 0.01). The frequency of G allele was higher in the 3 groups than in the healthy control group (P < 0.05, P < 0.01). The relative risk analysis showed that the risk for PCHD occurrence in G allele carriers at rs4343 (GG +AG) was 3. 6 times the risk in non-G allele carriers (95% CI: 1.224-10.585, P = 0.02). There was also statistical difference in sex, age, TC, and TG after adjusted Logistic regression analysis (OR = 3.994, 95% CI: 1.230-12.974, P = 0.021).

CONCLUSIONThe polymorphism at rs4343 (G2350A) might be one of risk factors for PCHD occurrence, but not a predisposing factor for PCHD patients of BSS.

Objective To observe the effect of Kangnaoye on angiogene-sis in rats after focal cerebral ischemia reperfusion.Methods The male SD rats were randomly divided into 6 groups: sham operation group , model group, Kangnaoye high, middle and low dosages groups (24,12,6 g· kg -1· d-1), and nimodipine group(1 mg· kg -1· d -1).The mod-els of cerebral ischemia reperfusion were established in rats by methods of middle cerebral artery occlusion ( MCAO).Immunohistochemical method was used to observe the change of the microvessel density ( MVD ) after cerebral ischemic and the expression of vascular endothelial growth ( VEG), HGF and CD31 protein of rats which were killed at the 0.5, 3, and 7 d of reperfusion injury respectively 2 h after cerebral ischemia.The nervous function deficit scores were evaluated at the 2 , 24 , and 48 h af-ter reperfusion.Results Compared with model group , the neurological behavior performance in Nimodipine and Kangnaoye treatment groups were significantly improved , with an increased number of MVD , and en-hanced vascular endothelial growth factor ( VEGF) and hepatocyte growth factor( HGF) protein levels ( P<0.05 or P<0.01 ) , especially in the Kangnaoye middle dosage group.Conclusion Kangnaoye has neuropro-tective effect against focal cerebral ischemic injury by improving the ex-pression of VEGF and HGF , which is one of possible anti -ischemic mechanisms.

Objective: To determine protein binding characteri stic and signal transmission pathway of melatonin（Mel） receptor(MR) in human e mbryonic peripheral organ tissues. Methods: MR was measured by radio ligand-binding assay and the effect of GTPγS on melatonin specific bindi ng was studied. Results: Mel specific binding sites were det ermined in 16 kinds of human embryonic tissue and this binding could be inhibit ed by GTPγS, supporting the theory that MR is coupled to inhibitory G-proteins system. Conclusion: MR is measured in human embryo tissue, the se results provide experimental data for elucidating the mechanism of the effect of Mel.

OBJECTIVETo explore the clinical outcomes of open reduction and internal fixation with calcaneal locking plates in treating Sanders type II and III calcaneal fractures.

METHODSFrom January 2010 and October 2012, 38 calcaneal fractures with Sanders type II or III were treated with open reduction and internal fixation with calcaneal locking plate. According to the Sanders classification, 15 fractures were classified as type II, 23 fractures as type III. The patients were divided into two groups (group A and B) according to the different fixed methods. Sustentaculum tali was fixed with one screw in group A, including 13 males and 5 females, with a mean age of (38.56±8.03) years old (ranged, 25 to 55). And sustentaculum tali was not fixed in group B, including 16 males and 4 females, with a mean age of (42.35±8.29) years old (ranged, 29 to 53). Clinical effects were evaluated according to the changes of Böhler's angle and the Maryland Foot Score and VAS score.

RESULTSAll patients were followed up from 12 to 20 months with a mean of 14 months. Böhler's angles and subtalar joints obtained satisfactory reconstruction in all patients. One year after operation, the mean Maryland Foot Score was 88.61±7.59 in group A; and was 82.40±9.24 in group B; Maryland Foot Score of group A was higher and foot functional rehabilitation was better than group B. The mean VAS score was 13.39±11.47 in group A; and was 22.50±13.10 in group B; VAS score of group A was lower and foot pain was less than group B.

CONCLUSIONSustentaculum tall screw fixation has advantages of strong fixed strength, high stability, less postoperative pain, rapid functional recovery in treating Sanders type II and III calcaneal fractures.

The combined application of statins that inhibit HMG-CoA reductase and fibrates that activate PPAR-α can produce a better lipid-lowering effect than the simple application, but with stronger adverse reactions at the same time. In the treatment of hyperlipidemia, the combined administration of TCMs and HMG-CoA reductase inhibitor in treating hyperlipidemia shows stable efficacy and less adverse reactions, and provides a new option for the combined application of drugs. In this article, the pharmacophore technology was used to search chemical components of TCMs, trace their source herbs, and determine the potential common TCMs that could activate PPAR-α. Because there is no hyperlipidemia-related medication reference in modern TCM classics, to ensure the high safety and efficacy of all selected TCMs, we selected TCMs that are proved to be combined with statins in the World Traditional/Natural Medicine Patent Database, analyzed corresponding drugs in pharmacophore results based on that, and finally obtained common TCMs that can be applied in PPAR-α and combined with statins. Specifically, the pharmacophore model was based on eight receptor-ligand complexes of PPAR-α. The Receptor-Ligand Pharmacophore Generation module in the DS program was used to build the model, optimize with the Screen Library module, and get the best sub-pharmacophore, which consisted of two hydrogen bond acceptor, three hydrophobic groups and 19 excluded volumes, with the identification effectiveness index value N of 2. 82 and the comprehensive evaluation index CAI value of 1. 84. The model was used to screen the TCMD database, hit 5,235 kinds of chemical components and 1 193 natural animals and plants, and finally determine 62 TCMs. Through patent retrieval, we found 38 TCMs; After comparing with the virtual screening results, we finally got seven TCMs.
