    Abstract The fluorinated decorations have recently been widely used in many biomedical applications. However, the potential mechanism of the fluorination effect on the cellular delivery of nanoparticles (NPs) still remains elusive. In this work, we systemically explore the penetration of a perfluoro-octanethiol-coated gold NP (PF-Au NP) and, for comparison, an octanethiol-coated gold NP (OT-Au NP) across lipid bilayers. We also investigated the effect of these two types of NPs on the properties of lipid bilayers. Our findings indicate that the lipid type and the surface tension of the lipid bilayer significantly impact the penetration capabilities of the fluorinated gold NP. By examining the distribution of ligands on the surface of the two types of NPs in water and during the penetration process, we unveil their distinct penetration characteristics. Specifically, the PF-Au NP exhibits amphiphobic behavior (both hydrophobic and lipophobic), while the OT-Au NP exhibits solely hydrophobic characteristics. Finally, we observe that the penetration capabilities can be increased by adjusting the degree of fluorination of the ligands on the NP surface. Overall, this study provides useful physical insights into the unique properties of the fluorinated decorations in NP permeation.

    Abstract Cognitive impairments in schizophrenia are pivotal clinical issues that need to be solved urgently. However, the mechanism remains unknown. It has been suggested that cognitive impairments in schizophrenia are associated with connectome damage, and are especially relevant to the disrupted hub nodes in the frontal and parietal lobes. Activating the dorsolateral prefrontal cortex (DLPFC) via repetitive transcranial magnetic stimulation (rTMS) could result in improved cognition. Based on several previous magnetic resonance imaging (MRI) studies on schizophrenia, we found that the first-episode patients showed connectome damage, as well as abnormal activation and connectivity of the DLPFC and inferior parietal lobule (IPL). Accordingly, we proposed that DLPFC-IPL pathway destruction might mediate connectome damage of cognitive impairments in schizophrenia. In the meantime, with the help of multimodal MRI and noninvasive neuromodulation tool, we may not only validate the hypothesis, but also find IPL as the potential intervention target for cognitive impairments in schizophrenia.

    Abstract Accurate calculation of protein-protein binding free energy is of great importance in biological and medical science, yet it remains a hugely challenging problem. In this work, we develop a new strategy in which a screened electrostatic energy (i.e., adding an exponential damping factor to the Coulombic interaction energy) is used within the framework of the molecular mechanics/Poisson-Boltzmann surface area (MM/PBSA) method. Our results show that the Pearson correlation coefficient in the modified MM/PBSA is over 0.70, which is much better than that in the standard MM/PBSA, especially in the Amber14SB force field. In particular, the performance of the standard MM/PBSA is very poor in a system where the proteins carry like charges. Moreover, we also calculated the mean absolute error (MAE) between the calculated and experimental Δ

    Abstract Major psychiatric disorders create a significant public health burden, and mental disorders such as major depressive disorder, bipolar disorder, and schizophrenia are major contributors to the national disease burden. The search for biomarkers has been a leading endeavor in the field of biological psychiatry in recent decades. And the application of cross-scale and multi-omics approaches combining genes and imaging in major psychiatric studies has facilitated the elucidation of gene-related pathogenesis and the exploration of potential biomarkers. In this article, we summarize the results of using combined transcriptomics and magnetic resonance imaging to understand structural and functional brain changes associated with major psychiatric disorders in the last decade, demonstrating the neurobiological mechanisms of genetically related structural and functional brain alterations in multiple directions, and providing new avenues for the development of quantifiable objective biomarkers, as well as clinical diagnostic and prognostic indicators.

    Abstract Catatonia is a psychomotor syndrome that can occur in a broad spectrum of brain disorders, including schizophrenia. Current findings suggest that the neurobiological process underlying catatonia symptoms in schizophrenia is poorly understood. However, emerging neuroimaging studies in catatonia patients have indicated that a disruption in anatomical connectivity of the cortico-striatal-cerebellar system is part of the neurobiology of catatonia, which could serve as a target of neurostimulation such as electroconvulsive therapy and repetitive transcranial magnetic stimulation.

    Abstract Rationale: Uterine abscess is a rare gynecologic entity and only a few cases have been reported so far. This study aimed to describe our clinical experience in this case. Initially, hematoma was diagnosed without detail previous medical record. Finally, laparotomy was performed due to refractory fever and highly possible diagnosis of uterine abscess. We successfully performed a hysterectomy and the patient had an uneventful recovery.
    Patient concerns: A 44-year-old nulliparous woman underwent myomectomy in the local hospital, 45 days ago. She complained of irregular fever (up to 40 °C) without abdominal pain since the surgery.
    Diagnoses: Due to lack of her detail medical record, equivocal images and her strong intention to preserve uterus, she was misdiagnosed with hematoma and treated with antibiotic treatment. Finally, intraoperative findings revealed that the huge myometrial abscess contained a mass of pus.
    Interventions: Laparotomy was performed due to refractory high-grade fever and highly possible diagnosis of uterine abscess. Total hysterectomy was performed to avoid the possibility of life-threatening sepsis.
    Outcomes: The postoperative course was uneventful and the patient was discharged 10 days after surgery.
    Lessons: Complete imaging examinations are recommended prior myomectomy to facilitate the differential diagnosis of postoperative complications. In addition, several measures, such as maintaining aseptic conditions during surgery and postoperative drainage, play a critical role in preventing nosocomial infections. Rare uterine abscess is often mistaken for hematoma with fever. If the patient develops high fever after myomectomy, accompanied by a mass in the myometrium, the possibility of infection or even abscess formation should not be excluded. For women who need to preserve their fertility, the early diagnosis and timely administration of appropriate medication is crucial for preventing uterine loss.

    Abstract Purpose: Quality follow-up (FU) is crucial after bariatric surgery. However, poor adherence after surgery is prevalent. This research aimed to explore the factors related to FU adherence after bariatric surgery in West China.
    Materials and methods: This study used a sequential explanatory mixed-methods research design. Participants (n = 177) were identified from the West China Hospital. Demographic information, disease profile, treatment information, and post-surgery FU information were obtained from the bariatric surgery database of the Division of Gastrointestinal Surgery of the West China Hospital. The survey data were analyzed using logistic regression. Semi-structured interviews with participants (n = 10) who had low adherence were conducted. The recording was transcribed verbatim and entered into qualitative data analysis software. Qualitative data were analyzed using a content analysis approach.
    Results: Multiple logistic regression revealed that living in Chengdu (OR, 2.308), being employed (OR, 2.532), non-smoking (OR, 2.805), and having less than five years of obesity (OR, 2.480) were positive predictors of FU adherence within one year. Semi-structured interviews suggested that factors related to adherence to FU were lack of motivation, lack of opportunity, insufficient ability, and beliefs regarding consequences.
    Conclusion: Factors impacting one-year FU visit adherence after bariatric surgery include not only demographic and disease-related factors but also social and family factors. These results will provide evidence to support healthcare professionals in developing personalized postoperative FU management strategies.

    Abstract Objective: To quantitatively analyze the myocardial work of patients with type 2 diabetes (T2D) by use of the pressure-strain loop and to investigate the clinical factors that affect myocardial work in the left ventricle.
    Methods: We analyzed data from 50 control patients and 180 case patients, with 70 cases in group A (T2D only), 40 cases in group B (T2D + high blood pressure), 33 cases in group C (T2D + coronary heart disease), and 37 cases in group D (T2D + high blood pressure + coronary heart disease). Each patient received conventional ultrasonography and 2-dimensional speckle-tracking echocardiography, and the pressure-strain loop technique was applied to measure the left ventricular myocardial work parameters to compare the control and case groups.
    Results: Systolic blood pressure was dramatically higher in groups B and D than in the control group and in groups A and C. N-terminal pro-brain natriuretic peptide was markedly higher in group D than in the control group, and the disease duration was markedly higher in groups C and D than in group A. The left ventricular global longitudinal strain of the epicardium (LVGLSepi) was substantially lower in groups B, C, and D than in the control group. The LVGLSepi of groups C and D was significantly lower than group A, and the LVGLSepi of group D was significantly lower than group B. The LVGLS, LVGLS of the endocardium, global work index, and global constructive work progressively reduced among the control and case groups. LVGLS strongly correlated with global work index (r = -0.886; P < .001) and global constructive work (r = -0.880; P < .001). Body mass index, duration of diabetes, and glycated hemoglobin A1c independently associated with global work index (Body mass index: P = .04; duration of diabetes: P < .001; glycated hemoglobin A1c: P = .02) . In addition to the above three indicators, systolic blood pressure independently associated with global constructive work (systolic blood pressure: P = .04).
    Conclusion: Pressure-strain loop technology can quantitatively, accurately, and sensitively monitor the variations in left ventricular myocardial contractile function of patients with T2D and detect subclinical cardiac injury at an early disease stage.

    Abstract The outbreak of the coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has become a worldwide public health crisis. When the SARS-CoV-2 enters the biological fluids in the human body, different types of biomolecules (in particular proteins) may adsorb on its surface and alter its infection ability. Although great efforts have recently been devoted to the interaction of specific antibodies with the SARS-CoV-2, it still remains largely unknown how the other serum proteins affect the infection of the SARS-CoV-2. In this work, we systematically investigate the interaction of serum proteins with the SARS-CoV-2 RBD by molecular docking and all-atom molecular dynamics simulations. It is found that non-specific immunoglobulins (Ig) indeed cannot effectively bind to the SARS-CoV-2 RBD while human serum albumin (HSA) may have some potential in blocking its infection (to ACE2). More importantly, we find that the RBD can cause significant structural changes in Apolipoprotein E (ApoE), by which SARS-CoV-2 may hijack the metabolic pathway of ApoE to facilitate its cell entry. The present study enhances the understanding of the role of protein corona in the bio-behaviors of SARS-CoV-2, which may aid the more precise and personalized treatment for COVID-19 infection in the clinic.

    Abstract Background: Cognitive impairment is the main factor in the poor prognosis of schizophrenia, but its mechanism remains unclear. The inferior parietal lobule (IPL) is related to various clinical symptoms and cognitive impairment in schizophrenia. We aimed to explore the relationship between IPL-related functions and cognitive impairment in schizophrenia.
    Methods: 136 schizophrenia patients and 146 demographically matched healthy controls were enrolled for a cross-sectional study. High-spatial-resolution structural and resting-state functional images were acquired to demonstrate the alternations of brain structure and function. At the same time, the digit span and digit symbol coding tasks of the Chinese Wechsler Adult Intelligence Test Revised (WAIS-RC) were utilized in assessing the subjects' cognitive function. Patients were divided into cognitive impairment and normal cognitive groups according to their cognitive score and then compared whether there were differences between the three groups in fractional amplitude of low-frequency fluctuation (fALFF). In addition, we did a correlation analysis between cognitive function and the fALFF for the left IPL of patients and healthy controls. Based on the Allen Human Brain Atlas, we obtained genes expressed in the left IPL, which were then intersected with the transcriptome-wide association study results and differentially expressed genes in schizophrenia.
    Results: Grouping of patients by the backward digit span task and the digit symbol coding task showed differences in fALFF values between healthy controls and cognitive impairment patients (P < 0.05). We found a negative correlation between the backward digit span task score and fALFF of the left IPL in healthy controls (r = - 0.388, P = 0.003), which was not seen in patients (r = 0.203, P = 0.020). In addition, none of the other analyses were statistically significant (P > 0.017). In addition, we found that diacylglycerol kinase ζ (DGKζ) is differentially expressed in the left IPL and associated with schizophrenia.
    Conclusion: Our study demonstrates that the left IPL plays a vital role in cognitive impairment in schizophrenia. DGKζ may act as an essential regulator in the left IPL of schizophrenia patients with cognitive impairment.
