The interest in covalent drugs has resurged in recent decades, spurring the development of numerous specialized computational docking tools to facilitate covalent ligand design and screening. Herein, we present CarsiDock-Cov, a new paradigm distinguishing itself as the first deep learning (DL)-guided approach for covalent docking. CarsiDock-Cov retains the core components of its non-covalent predecessor, leveraging a DL model pretrained on millions of docking complexes to predict protein-ligand distance matrices, along with a dedicated-designed geometric optimization procedure to convert these distances into refined binding poses. Additionally, it incorporates several key enhancements specifically tailored to optimize the protocol for covalent docking applications. Our approach has been extensively validated on multiple public datasets regarding the docking and screening of covalent ligands, and the results indicate that our approach not only achieves comparably improved applicability compared to its non-covalent predecessor, but also exhibits competitive performance against various state-of-the-art covalent docking tools. Collectively, our approach represents a significant advance in covalent docking methodology, offering an automated and efficient solution that shows considerable promise for accelerating covalent drug discovery and design.

Sensorineural hearing loss (SNHL), the most commonly-occurring form of hearing loss, is caused mainly by injury to or the loss of hair cells and spiral ganglion neurons in the cochlea. Numerous environmental and physiological factors have been shown to cause acquired SNHL, such as ototoxic drugs, noise exposure, aging, infections, and diseases. Several programmed cell death (PCD) pathways have been reported to be involved in SNHL, especially some novel PCD pathways that have only recently been reported, such as ferroptosis, necroptosis, and pyroptosis. Here we summarize these PCD pathways and their roles and mechanisms in SNHL, aiming to provide new insights and potential therapeutic strategies for SNHL by targeting these PCD pathways.

This paper summarized Professor LI Yueqing's clinical experience in treating prostate cancer by stages from the perspective of deficiency and stasis. It is believed that the onset of prostate cancer is due to kidney deficiency, while blood stasis is the core pathogenesis, and dampness-heat, phlegm-turbid, and cancer toxins are the key pathological factors in the progression of the disease. The pathogenesis in the early stage of the disease is kidney qi depletion and dampness, heat and phlegm coagulation; in the middle stage, it is spleen and kidney depletion, phlegm coagulation and blood stasis; and in the late stage, the pathogenesis changes into yin deficiency and essence depletion, and stasis-turbid toxin obstruction. For treatment, the basic principle is to supplement and boost kidney qi, enrich and nourish the kidney yin. The main treatment methods are draining dampness, dissolving phlegm, dispelling stasis, clearing heat and resolving toxins, and the method of invigorating blood and dispelling stasis runs through the whole course of treatment. In the early stage, radical treatment is mainly used, and Longshe Yangquan Decoction (龙蛇羊泉汤) with modifications is supplemented to clear and drain dampness and heat. In the middle stage, androgen deprivation therapy is the basic treatment, and Bushen Tongqiao Decoction (补肾通窍汤) with modifications is used in combination to nourish the spleen and kidney, dissolve phlegm and dispel stasis. In the late stage, Dabuyin Pills and Liuwei Dihuang Pills (大补阴丸合六味地黄丸) with modifications is mainly used to enrich yin and supplement essence, resolve toxins and dissolve stasis, and prevent cancer recurrence.

Expert systematic review on the choice of conduits for coronary artery bypass grafting: endorsed by the European Association for Cardio-Thoracic Surgery and the Society of Thoracic Surgeons published in 2023 made recommendations for the selection of bypass vessels. The left internal thoracic artery-anterior descending branch anastomosis represents the accepted gold standard. Radial artery could achieve a better long-term patency rate and a reduction in adverse cardiac events compared to the great saphenous vein. Radial artery graft using an open harvesting method should be chosen to graft the target vessel with low competitive coronary flow, with the use of vasodilators for the first year. There was no clear evidence of better patency for the right internal thoracic artery compared to the great saphenous vein. The bilateral internal thoracic artery had better long-term survival compared to great saphenous vein but may be associated with a higher risk of deep sternal wound infection and should be avoided in high-risk patients. The impact of skeletonization of the internal thoracic artery on graft patency and cardiovascular outcomes was unclear. Endoscopic vein harvest reduced the risk of leg wound complications and was associated with reduced long-term patency. The patency of the no-touch great saphenous vein was significantly better than that of conventional great saphenous vein. A significantly higher risk of complications at the harvesting site and no clear evidence of better long-term clinical outcomes were found in the no-touch great saphenous vein compared to the conventional. There was limited data on the use of right gastroepiploic artery and skeletonized harvesting, which should be used to bypass target vessels in patients with low competitive flow.

Chinese Journal of School Health 2024;45(1):66-71
Objective:
To understand current situation epidemiology and associated factors of suicidal ideation among high school students in Yixing, so as to provide basis for targeted intervention.
Methods:
From March to May 2019, a questionnaire survey was conducted on 12 799 students from 3 junior high schools and 4 senior high schools in Yixing City, Jiangsu Province, using a stratified cluster random sampling method. Latent profile analysis was used to classify suicidal ideation among high school students, the chi square test was used to compare the differences in suicidal ideation among different characteristics of students, multiple Logistic regression was used to analyze influencing factors, a risk predictive nomogram model was constructed and then verified.
Results:
Three latent classes of suicidal ideation among high school students was divided into three categories were observed: none or mild, moderate, and severe. Among them, 3 034 (23.7%) had moderate suicidal ideation and 753 (5.9%) had severe suicidal ideation. The Logistic regression results showed that gender was female, academic performance was lower midrange, smoking, drinking, popularity with classmates(less popular and unpopularity), family member relationships(general/occasional contradictions/contradictions), trust in others(more trusted/less trusted/less trusted at all), past or current relationships, physical bullying, relationship bullying, verbal bullying, and sexual bullying were the influencing factors for severe suicidal ideation among students ( OR =3.27; 2.18 ;1.63;1.72;2.66, 6.05;3.00,3.29, 6.38;1.71, 6.04, 12.48; 2.50; 1.59; 2.16; 1.45; 1.63, P <0.05). The nomogram prediction model had good discrimination.
Conclusions
Suicide ideation is influenced by multiple factors. Family and peer situations, as well as being bullied, are all related to the degree the severity of suicidal ideation. Efforts can be made to improve students family and interpersonal relationships, control bullying, then reduce their suicidal ideation which might help prevent suicide ideation among students.

Purpose:
Gastric cancer (GC) is among the deadliest malignancies and the third leading cause of cancer-related deaths worldwide. Galectin-1 (Gal-1) is a primary protein secreted by cancer-associated fibroblasts (CAFs); however, its role and mechanisms of action of Gal-1 in GC remain unclear. In this study, we stimulated GC cells with exogenous human recombinant galectin-1 protein (rhGal-1) to investigate its effects on the proliferation, migration, and resistance to cisplatin.
Materials and Methods:
We used simulated rhGal-1 protein as a paracrine factor produced by CAFs to induce GC cells and investigated its promotional effects and mechanisms in GC progression and cisplatin resistance. Immunohistochemical (IHC) assay confirmed that Gal-1 expression was associated with clinicopathological parameters and correlated with the expression of neuropilin-1 (NRP-1), c-JUN, and Wee1.
Results:
Our study reveals Gal-1 expression was significantly associated with poor outcomes.Gal-1 boosts the proliferation and metastasis of GC cells by activating the NRP-1/C-JUN/ Wee1 pathway. Gal-1 notably increases GC cell resistance to cisplatin The NRP-1 inhibitor, EG00229, effectively counteracts these effects.
Conclusions
These findings revealed a potential mechanism by which Gal-1 promotes GC growth and contributes to chemoresistance, offering new therapeutic targets for the treatment of GC.
