Objective To explore the clinical efficacy of robot-assisted coronary artery bypass grafting through a small incision in the left intercostal space in the treatment of multivessel coronary disease. Methods A retrospective analysis was conducted on the clinical data of patients who underwent coronary artery bypass grafting through a small incision in the left intercostal space at Central China Fuwai Hospital of Zhengzhou University from January 1, 2023 to October 15, 2024. Patients were divided into a robotic group and a minimally invasive group based on whether the surgery was assisted by the Da Vinci robot. Results A total of 81 patients were included, with 57 in the minimally invasive group, including 41 males and 16 females, with a median age of 65.0 (57.5, 69.5) years; and 24 in the robotic group, including 17 males and 7 females, with a median age of 61.0 (56.0, 69.0) years. There was no statistically significant difference in baseline data between the two groups (P>0.05). The robotic group had less intraoperative bleeding [300 (200, 438) mL vs. 500 (375, 600) mL, P=0.006], shorter postoperative mechanical ventilation time [15.0 (13.3, 23.5) h vs. 22.0 (15.5, 39.5) h, P=0.037], and lower incidence of postoperative pain [8 (33.3%) vs. 33 (57.9%), P=0.043]. The hospitalization cost in the robotic group was higher than that in the minimally invasive group [130491 (123298, 135691) yuan vs. 123892 (115543, 133449) yuan, P=0.023]. There was no statistical difference in postoperative laboratory indicators between the two groups (P>0.05). There was also no statistical difference in the duration of surgery, postoperative 24 h drainage volume, ICU stay time, postoperative hospital stay or incidences of perioperative compications including pleural effusion, transfusion, new-onset atrial fibrillation, acute kidney injury, non-union of incision, major cardiovascular and cerebrovascular adverse events, and reoperation between the two groups (P>0.05). Conclusion Compared with the minimally invasive group, the robotic group shows satisfactory efficacy and can effectively reduce postoperative pain and intraoperative bleeding, and shorten postoperative mechanical ventilation time.

Background::Hepatic ischemia-reperfusion injury (HIRI) remains a common complication during liver transplantation (LT) in patients. As a key downstream effector of the Hippo pathway, Yes-associated protein (YAP) has been reported to be involved in various physiological and pathological processes. However, it remains elusive whether and how YAP may control autophagy activation during ischemia-reperfusion.Methods::Human liver tissues from patients who had undergone LT were obtained to evaluate the correlation between YAP and autophagy activation. Both an in vitro hepatocyte cell line and in vivo liver-specific YAP knockdown mice were used to establish the hepatic ischemia-reperfusion models to determine the role of YAP in the activation of autophagy and the mechanism of regulation. Results::Autophagy was activated in the post-perfusion liver grafts during LT in patients, and the expression of YAP positively correlated with the autophagic level of hepatocytes. Liver-specific knockdown of YAP inhibited hepatocytes autophagy upon hypoxia-reoxygenation and HIRI ( P <0.05). YAP deficiency aggravated HIRI by promoting the apoptosis of hepatocytes both in the in vitro and in vivo models ( P <0.05). Attenuated HIRI by overexpression of YAP was diminished after the inhibition of autophagy with 3-methyladenine. In addition, inhibiting autophagy activation by YAP knockdown exacerbated mitochondrial damage through increasing reactive oxygen species ( P <0.05). Moreover, the regulation of autophagy by YAP during HIRI was mediated by AP1 (c-Jun) N-terminal kinase (JNK) signaling through binding to the transcriptional enhanced associate domain (TEAD). Conclusions::YAP protects against HIRI by inducing autophagy via JNK signaling that suppresses the apoptosis of hepatocytes. Targeting Hippo (YAP)-JNK-autophagy axis may provide a novel strategy for the prevention and treatment of HIRI.

Objective To systematically evaluate the effect of exercise therapy on body structure,function,and activity and partici-pation in patients with chronic nonspecific neck pain(CNSNP)based on the International Classification of Func-tioning,Disability and Health(ICF)framework. Methods A PICO framework was constructed,and randomized controlled trials(RCTs)on the intervention of different types of exercise therapy for patients with CNSNP were retrieved from databases of CBM,Wanfang data,VIP,CNKI,Cochrane Library,Embase,PubMed and Web of Science,from the establishment to March,2024.The quality of the literature was evaluated with Cochrane Risk of Bias Tool and Physiotherapy Evidence Database(PEDro)scale,and the evidence quality of the outcome indicators was evaluated using GRADE.Data were syn-thesized and analyzed using RevMan 5.3,and the risk of bias was evaluated using Stata 18.0. Results A total of eleven RCTs involving 668 subjects were included.The scores of PEDro scale were five to eight.The types of interventions included muscle strength training,stability training,proprioception training,Yoga and Pi-lates.The control groups received placebo,physical factor therapy and health education.Exercise therapy could increase the craniovertebral angle(SMD=0.84,95%CI 0.42 to 1.26,P<0.001),reduce the Visual Analogue Scale score(SMD=-2.05,95%CI-2.58 to-1.52,P<0.001),increase the pressure pain threshold(MD=112.27,95%CI 75.03 to 149.50,P<0.001),increase the range of motion of cervical forward(SMD=1.24,95%CI 0.34 to 2.15,P=0.007)and lateral(SMD=1.52,95%CI 0.40 to 2.65,P=0.008)flexion,and improve the endurance of the deep cervical flexors(SMD=1.02,95%CI 0.10 to 1.94,P=0.03)and position sense of the cervical spine(SMD=-1.00,95%CI-1.47 to-0.53,P<0.001);however,it was not significant in improving the range of motion of backward flexion(SMD=0.85,95%CI-1.04 to 2.75,P=0.38)and rotation(SMD=1.65,95%CI-0.35 to 3.65,P=0.11).Exercise therapy could also reduce the Neck Disability Index score(MD=-11.88,95%CI-16.09 to-7.68,P<0.001),and it was no significant in the Short-Form-36 score(MD=19.04,95%CI-3.00 to 41.08,P=0.09). Conclusion Exercise therapy can improve head posture,pain,motion of forward flexion and lateral flexion,endurance of the cervical flexors and joint position sense,and the overall function in patients with CNSNP.However,fur-ther researches are needed to verify the effects on cervical backward flexion and rotation,and quality of life.

Objective To investigate the anti-estrogenic activity of bisphenol A and its substitutes, and to analyze the relevant mechanisms. Methods Bisphenol A and its three most widely used substitutes (bisphenol S, bisphenol F and bisphenol AF) were selected as the docking ligand molecules, and estradiol was used as the control ligand molecule. The ligand molecules docking was simulated with estrogen receptor (ER) α and ERβ using AutoDock software. Results Bisphenol A forms a hydrogen bond with ERα at the His474 residue and with ERβ via three hydrogen bonds at Leu260, His428, and Asn431 residues. Similar to bisphenol A, bisphenol S, bisphenol F, bisphenol AF and estradiol primarily interact with ERα and ERβ through hydrophobic interactions and hydrogen bonds, but with varying optimal binding sites and affinities. The binding forces of the optimal binding sites for bisphenol A, bisphenol F, bisphenol AF, bisphenol S and estradiol with ERα were -4.15, -4.19, -2.73, -4.62 and -5.37 kcal/mol, respectively, and with ERβ were -3.76, -3.91, -2.86, -3.93, and -4.98 kcal/mol, respectively. The affinity ranking for two ERs with these five molecules from high to low was estradiol > bisphenol S> bisphenol F> bisphenol A > bisphenol AF. Conclusion The affinity between bisphenol compounds with ERα and ERβ is mainly based on the hydrophobic interaction with non-polar residues of the receptor and hydrogen bonding with key residues. Bisphenol S, bisphenol F and bisphenol AF showed similar or even stronger endocrine disrupting effects than bisphenol A.
