A simulation-based network analysis of intervention targets for adolescent depressive and anxiety symptoms.

Although previous research has well explored central and bridge symptoms of mental health problems, little examined whether these symptoms can serve as effective targets for intervention practices. Based on the Ising model, this study constructed a network structure of depressive and anxiety symptoms. The NodeIdentifyR algorithm (NIRA) was used to simulate interventions within this network, examining the effects of alleviating or aggravating specific symptoms on the network's sum scores. In this study, a total of 15,569 participants were recruited from China (50.87 % females, Mage = 13.44; SD = 0.97). The Ising model demonstrated that "sad mood" had the highest expected influence, and "irritability" had the highest bridge expected influence. Alleviating interventions suggested that decreasing the symptom value of "nervousness" resulted in the greatest projected reduction in network symptom activation, which may be a potential target symptom for treatment. Aggravating interventions indicated that elevating the symptom value of "sad mood" had the most projected increase in network activation, which may be a potential target for prevention. Additionally, network structure indices (e.g., central or bridge symptoms) need to be interpreted with more caution as intervention targets, since they may not be exactly the same. These findings enriched the comprehension of the depressive and anxiety network in Chinese adolescents, offering valuable insights for designing effective interventions.

Histone Lactylation Dynamics: Unlocking the Triad of Metabolism, Epigenetics, and Immune Regulation in Metastatic Cascade of Pancreatic Cancer.

Cancer cells rewire metabolism to sculpt the immune tumor microenvironment (TME) and propel tumor advancement, which intricately tied to post-translational modifications. Histone lactylation has emerged as a novel player in modulating protein functions, whereas little is known about its pathological role in pancreatic ductal adenocarcinoma (PDAC) progression. Employing a multi-omics approach encompassing bulk and single-cell RNA sequencing, metabolomics, ATAC-seq, and CUT&Tag methodologies, we unveiled the potential of histone lactylation in prognostic prediction, patient stratification and TME characterization. Notably, "LDHA-H4K12la-immuno-genes" axis has introduced a novel node into the regulatory framework of "metabolism-epigenetics-immunity," shedding new light on the landscape of PDAC progression. Furthermore, the heightened interplay between cancer cells and immune counterparts via Nectin-2 in liver metastasis with elevated HLS unraveled a positive feedback loop in driving immune evasion. Simultaneously, immune cells exhibited altered HLS and autonomous functionality across the metastatic cascade. Consequently, the exploration of innovative combination strategies targeting the metabolism-epigenetics-immunity axis holds promise in curbing distant metastasis and improving survival prospects for individuals grappling with challenges of PDAC.

"Still work?" Design and effect of interventions used to modify feeding problems in children with autism: A systematic review of studies employing group designs.

BACKGROUND: Feeding problems in children with autism jeopardize the well-being of both children with autism and their families. Mixed findings were reported from previous interventions, which were mostly evaluated by single subject research design (SSRD) studies. Moreover, feasibility assessment and social validity measurement were unaddressed by these SSRD studies. To fill this substantial knowledge gap, the present review systematically summarized and evaluated feeding interventions implemented in children with autism, which were assessed by studies employing group designs. METHOD: An extensive literature search in eight established online databases was conducted, and a total of 17 eligible studies published in 2009-2021 were included for further analysis. A descriptive account of the features of the investigations is provided, including assessment of study quality. RESULTS: A total of 449 children with autism and 203 parents/caregivers participated in the included studies. The multiple use of five strategic intervention components were highlighted in this review, including nutrition education/consultations, environmental modifications, sensory exposure, cognitive components, and behaviour interventions. The reviewed interventions showed a preliminarily positive effect for modifying feeding problems in children with autism. Furthermore, the evaluation based on the RE-AIM framework (reach, efficacy, adoption, implementation, and maintenance) demonstrated that an interdisciplinary multi-component intervention strategy may achieve high effectiveness and feasibility in improving feeding problems in a wide range of children with autism. CONCLUSIONS: This review found that interventions achieved and maintained a positive effect on modification of feeding problems in groups of children with autism. Information and gaps identified and summarized in the implementation process may assist both researchers and stakeholders to further support these vulnerable children.

Helicobacter pylori-Induced Angiopoietin-Like 4 Promotes Gastric Bacterial Colonization and Gastritis.

Helicobacter pylori infection is characterized as progressive processes of bacterial persistence and chronic gastritis with features of infiltration of mononuclear cells more than granulocytes in gastric mucosa. Angiopoietin-like 4 (ANGPTL4) is considered a double-edged sword in inflammation-associated diseases, but its function and clinical relevance in H. pylori-associated pathology are unknown. Here, we demonstrate both pro-colonization and pro-inflammation roles of ANGPTL4 in H. pylori infection. Increased ANGPTL4 in the infected gastric mucosa was produced from gastric epithelial cells (GECs) synergistically induced by H. pylori and IL-17A in a cagA-dependent manner. Human gastric ANGPTL4 correlated with H. pylori colonization and the severity of gastritis, and mouse ANGPTL4 from non-bone marrow-derived cells promoted bacteria colonization and inflammation. Importantly, H. pylori colonization and inflammation were attenuated in Il17a -/-, Angptl4 -/-, and Il17a -/- Angptl4 -/- mice. Mechanistically, ANGPTL4 bound to integrin αV (ITGAV) on GECs to suppress CXCL1 production by inhibiting ERK, leading to decreased gastric influx of neutrophils, thereby promoting H. pylori colonization; ANGPTL4 also bound to ITGAV on monocytes to promote CCL5 production by activating PI3K-AKT-NF-κB, resulting in increased gastric influx of regulatory CD4+ T cells (Tregs) via CCL5-CCR4-dependent migration. In turn, ANGPTL4 induced Treg proliferation by binding to ITGAV to activate PI3K-AKT-NF-κB, promoting H. pylori-associated gastritis. Overall, we propose a model in which ANGPTL4 collectively ensures H. pylori persistence and promotes gastritis. Efforts to inhibit ANGPTL4-associated pathway may prove valuable strategies in treating H. pylori infection.

ROR2 promotes invasion and chemoresistance of triple-negative breast cancer cells by activating PI3K/AKT/mTOR signaling.

Objective: This study aimed to investigate the role of receptor tyrosine kinase-like orphan receptor 2 (ROR2) in triple-negative breast cancer (TNBC). Methods: ROR2 expression in primary TNBC and metastatic TNBC tissues was analyzed by immunohistochemical staining and PCR. ROR2 expression in TNBC cell lines was detected by PCR and Western blot analysis. The migration, invasion and chemosensitivity of TNBC cells with overexpression or knockdown of ROR2 were examined. Results: ROR2 expression was high in metastatic TNBC tissues. ROR2 knockdown suppressed the migration, invasion and chemoresistance of TNBC cells. ROR2 overexpression in MDA-MB-435 cells promoted the migration, invasion, and chemoresistance. Moreover, ROR2 knockdown in HC1599 and MDA-MB-435 adriamycin-resistant cells enhanced chemosensitivity to adriamycin. ROR2 could activate PI3K/AKT/mTOR signaling in TNBC cells. Conclusion: ROR2 is upregulated and promotes metastatic phenotypes of TNBC by activating PI3K/AKT/mTOR signaling.

Prognostic impact of new-onset atrial fibrillation in myocardial infarction with and without improved ejection fraction.

AIMS: Improvement in left ventricular ejection fraction (impEF) often presents in contemporary acute myocardial infarction (AMI) patients. New-onset atrial fibrillation (NOAF) during AMI is an important predictor of subsequential heart failure (HF), while its impact on the trajectory of post-MI left ventricular ejection fraction (LVEF) and prognostic implication in patients with and without impEF remains undetermined. We aimed to investigate the prognostic impacts of NOAF in AMI patients with and without impEF. METHODS AND RESULTS: Consecutive AMI patients without a prior history of AF between February 2014 and March 2018 with baseline LVEF ≤ 40% and had ≥1 LVEF measurement after baseline were included. ImpEF was defined as a baseline LVEF ≤ 40% and a re-evaluation showed both LVEF > 40% and an absolute increase of LVEF ≥ 10%. Persistently reduced EF (prEF) was defined as the second measurement of LVEF either ≤40% or an absolute increase of LVEF < 10%. The primary endpoint was a major adverse cardiac event (MACE) that was composed of cardiovascular death and HF hospitalization. Cox regression analysis and competing risk analysis were performed to assess the association of post-MI NOAF with MACE. Among 293 patients (mean age: 66.6 ± 11.3 years, 79.2% of males), 145 (49.5%) had impEF and 67 (22.9%) developed NOAF. Higher heart rate (odds ratio [OR]: 0.84, 95% confidence interval [CI]: 0.73-0.97; P = 0.015), prior MI (OR: 0.25, 95% CI: 0.09-0.69; P = 0.008), and STEMI (OR: 0.40, 95% CI: 0.21-0.77; P = 0.006) were independent predictors of post-MI impEF. Within up to 5 years of follow-up, there were 22 (15.2%) and 53 (35.8%) MACE in patients with impEF and prEF, respectively. NOAF was an independent predictor of MACE in patients with impEF (hazard ratio [HR]: 7.34, 95% CI: 2.49-21.59; P < 0.001) but not in those with prEF (HR: 0.78, 95% CI: 0.39-1.55; P = 0.483) after multivariable adjustment. Similar results were obtained when accounting for the competing risk of all-cause death (subdistribution HR and 95% CIs in impEF and prEF were 6.47 [2.32-18.09] and 0.79 [0.39-1.61], respectively). CONCLUSIONS: The NOAF was associated with an increased risk of cardiovascular outcomes in AMI patients with impEF.

Efficacy of first-line chemotherapy based on primary site of tumor versus etoposide-platinum in advanced gastroenteropancreatic neuroendocrine carcinoma.

Background: Gastroenteropancreatic neuroendocrine carcinomas (GEP-NECs) constitute a rare and aggressive group of malignancies usually with widespread disease. There are limited studies on GEP-NECs, and therefore, we aim to acquire more information on the clinical features, treatment regimens, and prognosis. Methods: Data from advanced GEP-NECs patients who had not previously received systemic treatment for advanced disease at The First Affiliated Hospital of Nanjing Medical University from 2010 to 2022 were retrospectively collected. Relationships between clinical-pathological features, treatment regimens, and prognosis were investigated using Kaplan-Meier curves and cox regression models. Results: A total of fifty-four patients were enrolled in the study. The median age was 65.5 years and 79.6% were male. At diagnosis, 51.9% and 3.7% of patients developed liver and brain metastasis respectively. Sixteen (29.6%) patients received chemotherapy according to primary site of tumor (PST), while thirty-eight (70.4%) were treated with etoposide-platinum (EP) regimen, which based on the first-line treatment of advanced small cell lung cancer (SCLC). No significant differences on progression-free survival (PFS) and response rate were observed between these two groups. Univariate survival analysis showed that liver metastasis, elevated baseline serum carcinoembryonic antigen, elevated baseline serum neuron-specific enolase, elevated baseline serum lactate dehydrogenase, and elevated baseline serum neutrophil-to-lymphocyte ratio (NLR) were associated with shorter PFS. After multivariate analysis, elevated NLR was the only factor that remained significantly associated with shorter PFS (P=0.01). Conclusions: GEP-NECs are aggressive neoplasms, of which elevated NLR is proven to be an independent negative predictor. Treatment regimens based on PST are not inferior to regiments based on SCLC (EP) for GEP-NECs patients. Large-scale, prospective randomized controlled trials are required to establish the standard of care.

Fecal virome transplantation: A promising strategy for the treatment of metabolic diseases.

Metabolic diseases are a group of disorders caused by metabolic abnormalities, including obesity, diabetes, non-alcoholic fatty liver disease, and more. Increasing research indicates that, beyond inherent metabolic irregularities, the onset and progression of metabolic diseases are closely linked to alterations in the gut microbiota, particularly gut bacteria. Additionally, fecal microbiota transplantation (FMT) has demonstrated effectiveness in clinically treating metabolic diseases, notably diabetes. Recent attention has also focused on the role of gut viruses in disease onset. This review first introduces the characteristics and influencing factors of gut viruses, then summarizes their potential mechanisms in disease development, highlighting their impact on gut bacteria and regulation of host immunity. We also compare FMT, fecal filtrate transplantation (FFT), washed microbiota transplantation (WMT), and fecal virome transplantation (FVT). Finally, we review the current understanding of gut viruses in metabolic diseases and the application of FVT in treating these conditions. In conclusion, FVT may provide a novel and promising treatment approach for metabolic diseases, warranting further validation through basic and clinical research.

Immune mediated support of metastasis: Implication for bone invasion.

Bone is a common organ affected by metastasis in various advanced cancers, including lung, breast, prostate, colorectal, and melanoma. Once a patient is diagnosed with bone metastasis, the patient's quality of life and overall survival are significantly reduced owing to a wide range of morbidities and the increasing difficulty of treatment. Many studies have shown that bone metastasis is closely related to bone microenvironment, especially bone immune microenvironment. However, the effects of various immune cells in the bone microenvironment on bone metastasis remain unclear. Here, we described the changes in various immune cells during bone metastasis and discussed their related mechanisms. Osteoblasts, adipocytes, and other non-immune cells closely related to bone metastasis were also included. This review also summarized the existing treatment methods and potential therapeutic targets, and provided insights for future studies of cancer bone metastasis.

Glutathione-activated biotin-targeted dual-modal imaging probe with improved PDT/PTT synergistic therapy.

BACKGROUND: Glutathione (GSH), a highly abundant thiol compound within cells, plays a critical role in physiological processes and exhibits close correlation with cancer. Among molecular imaging technologies, most probes have relatively short emission wavelengths and lack photoacoustic imaging (PA) capability, resulting in the inability to obtain tissue images with high penetration depth. The presence of GSH in the tumor microenvironment neutralizes ROS, diminishing the therapeutic effect of PDT, thus resulting in often unsatisfactory therapeutic efficacy. Therefore, it is imperative to develop a dual-modal probe for the detection of GSH and the diagnosis and treatment of cancer. RESULTS: In this study, we synthesized a novel dual-modal probe, Cy-Bio-GSH, utilizing near-infrared fluorescence (NIRF) and photoacoustic (PA) imaging techniques for GSH detection. The probe integrates cyanine dye as the fluorophore, nitroazobenzene as the recognition moiety, and biotin as the tumor-targeting moiety. Upon reacting with GSH, the probe emits NIR fluorescence at 820 nm and generates a PA signal. Significantly, this reaction activates the photodynamic and photothermal properties of the probe. By depleting GSH and employing a synergistic photothermal therapy (PTT) treatment, the therapeutic efficacy of photodynamic therapy (PDT) is remarkably enhanced. In-vivo experiments confirm the capability of the probe to detect GSH via NIRF and PA imaging. Notably, the combined tumor-targeting ability and PDT/PTT synergistic therapy enhance therapeutic outcomes for tumors and facilitate their ablation. SIGNIFICANCE: A novel tumor-targeting and dual-modal imaging probe (Cy-Bio-GSH) is synthesized, exhibiting remarkable sensitivity and selectivity to GSH, enabling the visualization of GSH in cells and the differentiation between normal and cancer cells. Cy-Bio-GSH enhances PDT/PTT with effective killing of cancer cells and makes the ablation of tumors in mice. This work represents the first tumor-targeting probe for GSH detection, and provides crucial tool for cancer diagnosis and treatment by dual-modal imaging with improved PDT/PTT synergistic therapy.

Development and validation of machine learning models to predict MDRO colonization or infection on ICU admission by using electronic health record data.

BACKGROUND: Multidrug-resistant organisms (MDRO) pose a significant threat to public health. Intensive Care Units (ICU), characterized by the extensive use of antimicrobial agents and a high prevalence of bacterial resistance, are hotspots for MDRO proliferation. Timely identification of patients at high risk for MDRO can aid in curbing transmission, enhancing patient outcomes, and maintaining the cleanliness of the ICU environment. This study focused on developing a machine learning (ML) model to identify patients at risk of MDRO during the initial phase of their ICU stay. METHODS: Utilizing patient data from the First Medical Center of the People's Liberation Army General Hospital (PLAGH-ICU) and the Medical Information Mart for Intensive Care (MIMIC-IV), the study analyzed variables within 24 h of ICU admission. Machine learning algorithms were applied to these datasets, emphasizing the early detection of MDRO colonization or infection. Model efficacy was evaluated by the area under the receiver operating characteristics curve (AUROC), alongside internal and external validation sets. RESULTS: The study evaluated 3,536 patients in PLAGH-ICU and 34,923 in MIMIC-IV, revealing MDRO prevalence of 11.96% and 8.81%, respectively. Significant differences in ICU and hospital stays, along with mortality rates, were observed between MDRO positive and negative patients. In the temporal validation, the PLAGH-ICU model achieved an AUROC of 0.786 [0.748, 0.825], while the MIMIC-IV model reached 0.744 [0.723, 0.766]. External validation demonstrated reduced model performance across different datasets. Key predictors included biochemical markers and the duration of pre-ICU hospital stay. CONCLUSIONS: The ML models developed in this study demonstrated their capability in early identification of MDRO risks in ICU patients. Continuous refinement and validation in varied clinical contexts remain essential for future applications.

Relationship between childhood trauma and non-suicidal self-injury in high school students: the mediating role of the stress perception and the moderating role of teacher-student relationship.

This study delves into the correlation between childhood trauma and non-suicidal self-injury (NSSI) behaviors among high school students. Additionally, it examines the mediating role of stress perception and the moderating role of the teacher-student relationship in this association. A questionnaire survey was administered to 1,329 high school students in Yunnan Province to assess childhood trauma, NSSI behaviors, and stress perception. Firstly, the survey revealed a 12% prevalence of NSSI, with girls exhibiting a higher occurrence compared to boys (OR = 0.413, 95% CI: 0.280-0.609). Secondly, childhood trauma emerged as a significant predictor of NSSI behavior, irrespective of gender or whether the individual was an only child (r = 0.17, P < 0.01). Thirdly, stress perception functioned as a mediator in the relationship between childhood trauma and NSSI among high school students (t = 4.65, P < 0.01). The mediation effect occupies 26.56% of the total effect. Furthermore, the teacher-student relationship moderated the mediating effect of stress perception on the link between childhood trauma and NSSI (ß = 0.0736, P < 0.01). Notably, individuals with strong teacher-student relationships exhibited a significant elevation in stress perception upon exposure to childhood trauma. The findings of this study support a moderated mediation model in the association between childhood trauma and NSSI, suggesting profound implications for the development of targeted interventions and prevention strategies among high school students.

Argonaute 2 restored erectile function and corpus cavernosum mitochondrial function by reducing apoptosis in a mouse model of cavernous nerve injury.

PURPOSE: To determine whether the overexpression of the Argonaute RNA-induced silencing complex catalytic component 2 (Ago2) improves erectile function in mice after cavernous nerve injury (CNI). MATERIALS AND METHODS: Lentiviruses containing Ago2 open reading frame (ORF) mouse clone (Ago2 O/E) were used to overexpress Ago2, and lentiviruses ORF negative control particles (NC) were used as a negative control. Three days before preparing the CNI model, we injected lentiviruses into the penises of 8-week-old male C57BL/6 mice. Animals were then divided into four groups: the sham operation control group and the CNI+phosphate-buffered saline, CNI+NC, and CNI+Ago2 O/E groups. One week later, erectile function was assessed by electrically stimulating cavernous nerves bilaterally and obtaining intracavernous pressure parameters. Penile tissue was also collected for molecular mechanism studies. RESULTS: Ago2 overexpression improved erectile function in mice after CNI-induced erectile dysfunction (ED). Immunofluorescence staining and Western blot analysis showed that under Ago2 overexpressing conditions, the contents of endothelial cells, pericytes, and neuronal cells increased in the penile tissues of CNI mice, and this was attributed to reduced apoptosis and ROS production. In addition, we also found that Ago2 overexpression could restore penile mitochondrial function, thereby improving erectile function in CNI-induced ED mice. CONCLUSIONS: Our findings demonstrate that Ago2 overexpression can reduce penile cell apoptosis, restore penile mitochondrial function, and improve erectile function in CNI-induced ED mice.

Supine position popliteal vein puncture under ultrasound guidance is a feasible and effective strategy to establish venous access.

OBJECTIVE: This study aims to introduce the clinical application value of popliteal vein puncture in the supine position under ultrasound guidance and compare this method with popliteal vein puncture in the prone position. METHODS: Endovascular operations for nonthrombotic iliac vein lesions (NIVLs) patients using popliteal vein access were performed during the period from July 2019 to August 2022 at the Zhongshan Hospital (Xiamen), Fudan University and Shanghai Xuhui District Central Hospital. Patients were randomly divided into supine position group and prone position group. All of the patients were punctured under ultrasound guidance. The procedure duration time for popliteal vein puncture, visual analogue score (VAS) scores and postoperative complications were recorded and compared between the two groups. RESULTS: Totally 120 patients were included in this study, in which 60 patients were enrolled in the supine position group, and 60 patients were enrolled in the prone position group. The median procedure time from puncture to iliofemoral venography was 5.97 min (interquartile range 5.78 min -6.03 min) and 28.76min (interquartile range 26.84 min -29.83 min ; p＜0.01）in the supine position and prone position group, respectively. The median time from puncture to access sheath insertion was 5.05 min (interquartile range 4.88 min -5.13 min ) and 5.03 min (interquartile range 4.93 min-5.12 min; p =0.607）in the supine position and prone position group, respectively. The median VAS value was 3 (interquartile range 2-3 ) and 8 (interquartile range 7-9 , p＜0.01）in the supine position and prone position group, respectively. In the supine position group, 1 case of arterial branch injury was observed after operation, and was successfully managed by ultrasound-guided compression. CONCLUSIONS: Popliteal vein puncture in the supine position under ultrasound guidance is safe and significantly reduces the overall operation time without changing position, and relieves the discomfort of patients.

Scalp acupuncture targets for neurological disorders：evidence from neuroimaging studies (part 2). / åŸºäºŽç¥žç»å½±åƒå­¦çš„å¸¸è§ç¥žç»ç³»ç»Ÿç–¾ç— å¤´é’ˆåˆºæ¿€é¶ç‚¹ç ”ç©¶ï¼ˆä¸‹ï¼‰.

OBJECTIVES: Scalp acupuncture is a method of treating diseases by dividing and stimulating the corresponding function-oriented cortical scalp areas. It is a commonly used therapy for neurological disorders. However, the specific target selection for scalp acupuncture remains to be explored. This manuscript aims to initiate an attempt to develop/identify scalp acupuncture targets based on neuroimaging findings and noninvasive brain stimulation. METHODS: Neurosynth-based meta-analysis of neuroimaging studies was conducted to identify brain stimulation targets of neurological disorders. The identified target regions were further projected to the scalp. The traditional acupoints and 10-20 EEG system were referenced for the localization of these targets. In this study, the "mild cognitive impairment" (MCI), "Alzheimer's disease" (AD) and "dementia" were used as the retrieval terms respectively, and a unity detection method was used to generate brain maps, with the default FDR (false discovery rate, P<0.01) threshold of Neurosynth set for subsequent exploration of various disease-related brain regions. The literature search was conducted on July 30, 2022. RESULTS: The localization and manipulation suggestions of neuroimage-based scalp acupuncture targets for MCI, AD, and dementia were introduced in the present paper (part 2). Here are 3 target examples for each of these 3 diseases due to word limitation. 1) MCI：Based on the 81 papers retrieved, we identified 6 potential scalp acupuncture points for MCI, their corresponding brain regions, brain functions and the possible resultant effects of the scalp target acupoint stimulation respectively are as below. MCI1：the orbital part of the left inferior frontal gyrus (left Brodmann area ［BA］47), related to semantic coding, working memory and episodic memory, improving semantic coding and memory function；MCI2：the anterior motor area/left anterior central gyrus (left BA6), the motor center area, improving MCI motor function；MCI3：the left medial temporal gyrus (left BA21), related to the processing of speech, visual space, language and word understanding, improving language and memory. 2) AD：Based on the 196 papers retrieved, we found 6 potential scalp acupuncture targets for AD, their corresponding brain regions and brain functions of the 3 example targets respectively are as below. AD1：the left medial temporal gyrus (left BA21), participating in language and semantic processing, sentence and word generation, intent expression, deductive reasoning；AD2：the left angular gyrus (left BA39), related to semantic processing, word reading and comprehension, memory retrieval, attention and spatial cognition, reasoning, etc.；AD3：the left fusiform/suboccipital gyrus (left BA37), related to semantic classification, text generation, sign language, phonology processing, etc. 3) Dementia：Based on the 142 papers retrieved, we found 4 potential scalp acupuncture targets for dementia, their corresponding brain regions, brain functions and the possible targets of the proposed scalp stimulation respectively are as below. D1 and D2：the left inferior frontal gyrus (i.e., left BA46, and left BA47, respectively), being closely related to working memory, emotional response regulation, melody and other processing processes, may be suitable for treating memory decline and advanced executive dysfunction in patients with dementia；D3：the left medial temporal gyrus (left BA21), an important brain region for various sensory integration, cognitive processing and memory functions, and emotional processing, may be suitable for temporal dementia. CONCLUSIONS: We identified scalp acupuncture targets for several common neurological disorders based on neuroimaging findings and noninvasive brain stimulation. The proposed targets may also be used for treating these disorders using nerve/brain stimulation methods.

Scalp acupuncture targets for neurological disorders：evidence from neuroimaging studies (part 1). / åŸºäºŽç¥žç»å½±åƒå­¦çš„å¸¸è§ç¥žç»ç³»ç»Ÿç–¾ç— å¤´é’ˆåˆºæ¿€é¶ç‚¹ç ”ç©¶ï¼ˆä¸Šï¼‰.

OBJECTIVES: Scalp acupuncture is a unique acupuncture method developed based on brain functional and pathophysiological knowledge. In past decades, there has been significant development in the understanding of the brain pathology of many neurological disorders through cutting-edge brain imaging techniques. Yet, these findings have not been incorporated into scalp acupuncture. In the present paper, we aimed to initiate an attempt to develop/identify scalp acupuncture targets based on neuroimaging findings. METHODS: Based on the meta-analysis of neuroimaging studies in the Neurosynth database platform (http：//neurosynth.org/), the brain clusters related to neurological disorders were automatically identified according to the search terms "Parkinson's disease"(PD), "chronic pain"(CP), "aphasia"(APH), "dyslexia"(DYS), "mild cognitive impairment", "Alzheimer's disease" and "dementia". Subsequently, the discovered brain region clusters projected onto the brain surface and scalp surface were listed, and the peak points of the clusters projected to the scalp surface were proposed as the potential stimulation targets for the corresponding diseases. Further, by combining the traditional scalp acupoints (including the scalp acupuncture lines) with 10-20 EEG system sites, we made localization suggestions for scalp stimulation targets and made acupuncture operation suggestions by combining with the shape of the brain region clusters. The literature search was conducted on July 30, 2022. RESULTS: The localization and manipulation suggestions of neuroimage-based scalp acupuncture targets were introduced in two parts. This part (part 1) includes PD, CP, APH, and DYS. Here are 3 target examples of each of these 4 diseases simply introduced due to word limitation. 1) PD. Based on the 175 articles retrieved from Neurosynth, we identified 7 potential scalp acupuncture targets for PD, the locations of the acupuncture stimulation and the recommended acupuncture needle operation (RANO) as well as the corresponding brain regions (CBRs) respectively are as below. PD1：about 0.5 cun (1 cun≈33.3 mm) superior-posterior to the left Xuanlu (GB5)；puncturing subcutaneously and forward-upward；the left premotor area, subfrontal cortex of the island, inferior frontal gyrus and middle frontal gyrus. PD2：about 1 cun lateral-inferior to the left Chengling (GB18)；puncturing subcutaneously and backward-upward；the inferior parietal lobule and postcentral gyrus. PD3：about 0.5 cun lateral-anterior to the left GB18；puncturing subcutaneously and inward-backward；left anterior central gyrus and posterior central gyrus. 2) CP. Based on the retrieved 92 articles, we identified 8 potential scalp acupuncture targets, the location of the acupuncture stimulation and the RANO, and CBRs respectively are as below. CP1：about 1 cun anterior-inferior to the left Xuanli (GB8)；puncturing subcutaneously and backward-inwards；the left inferior frontal gyrus orbitalis and pars triangularis. CP2：about 0.5 cun posterior-superior to the left GB5；puncturing subcutaneously and forward-upward；the left anterior central gyrus and premotor area. CP3：about 0.5 cun posterior-superior to the left GB8；puncturing subcutaneously and forward；left inferior central area/central sulci operculum (second somatosensory area). 3) APH. Based on the retrieved 82 papers, we identified 7 potential scalp acupuncture targets for APH, their locations, RANO, and CBRs respectively are as below. APH1：close to the left GB5；puncturing subcutaneously and forward-downward；left subfrontal gyrus operculi/triangularis. APH2：about 0.5 cun posterior to the left Hanyan (GB4)；puncturing subcutaneously and backward-upward；the left anterior central gyrus and posterior central gyrus. APH3：about 0.5 cun anterior-inferior to the left Qubin (GB7)；puncturing subcutaneously and backward-downward；left medial/superior temporal gyrus. 4) DYS. Based on the retrieved 76 researches, we identified 8 potential scalp acupuncture targets for DYS, their locations, RANO and CBRs respectively are as below. DYS1：about 1 cun anterior-inferior to the left GB5；puncturing subcutaneously and forward-upward；the pars triangularis of the left inferior frontal gyrus. DYS2：about 0.5 cun posterior-superior to the left GB5；puncturing subcutaneously and forward-downward；the left subfrontal gyrus operculum, pars triangularis and anterior central gyrus. DYS3：the midpoint between the left GB5 and GB18；puncturing subcutaneously and forward；the left anterior central gyrus and posterior central gyrus. CONCLUSIONS: We identified scalp acupuncture targets for several common neurological disorders based on neuroimaging evidence for clinical application and research. The proposed targets may also be used for treating these disorders using brain stimulation methods.

DMLS: an automated pipeline to extract the Drosophila modular transcription regulators and targets from massive literature articles.

Transcription regulation in multicellular species is mediated by modular transcription factor (TF) binding site combinations termed cis-regulatory modules (CRMs). Such CRM-mediated transcription regulation determines the gene expression patterns during development. Biologists frequently investigate CRM transcription regulation on gene expressions. However, the knowledge of the target genes and regulatory TFs participating in the CRMs under study is mostly fragmentary throughout the literature. Researchers need to afford tremendous human resources to fully surf through the articles deposited in biomedical literature databases in order to obtain the information. Although several novel text-mining systems are now available for literature triaging, these tools do not specifically focus on CRM-related literature prescreening, failing to correctly extract the information of the CRM target genes and regulatory TFs from the literature. For this reason, we constructed a supportive auto-literature prescreener called Drosophila Modular transcription-regulation Literature Screener (DMLS) that achieves the following: (i) prescreens articles describing experiments on modular transcription regulation, (ii) identifies the described target genes and TFs of the CRMs under study for each modular transcription-regulation-describing article and (iii) features an automated and extendable pipeline to perform the task. We demonstrated that the final performance of DMLS in extracting the described target gene and regulatory TF lists of CRMs under study for given articles achieved test macro area under the ROC curve (auROC) = 89.7% and area under the precision-recall curve (auPRC) = 77.6%, outperforming the intuitive gene name-occurrence-counting method by at least 19.9% in auROC and 30.5% in auPRC. The web service and the command line versions of DMLS are available at https://cobis.bme.ncku.edu.tw/DMLS/  and  https://github.com/cobisLab/DMLS/, respectively.

Immune cell phenotypes and mortality in the Framingham Heart Study.

BACKGROUND: Global life expectancy is rising, with the 60 + age group projected to hit 2 billion by 2050. Aging impacts the immune system. A notable marker of immune system aging is the presence of Aging-Related Immune Cell Phenotypes (ARIPs). Despite their importance, links between immune cell phenotypes including ARIPs and mortality are underexplored. We prospectively investigated 16 different immune cell phenotypes using flow cytometry and IL-6 in relation to survival outcome among dementia-free Framingham Heart Study (FHS) offspring cohort participants who attended the seventh exam (1998-2001). RESULTS: Among 996 participants (mean age 62 years, range 40 to 88 years, 52% female), the 19-year survival rate was 65%. Adjusting for age, sex, and cytomegalovirus (CMV) serostatus, higher CD4/CD8 and Tc17/CD8 + Treg ratios were significantly associated with lower all-cause mortality (HR: 0.86 [0.76-0.96], 0.84 [0.74-0.94], respectively), while higher CD8 regulatory cell levels (CD8 + CD25 + FoxP3 +) were associated with increased all-cause mortality risk (HR = 1.17, [1.03-1.32]). Elevated IL-6 levels correlated with higher all-cause, cardiovascular, and non-cardiovascular mortality (HR = 1.43 [1.26-1.62], 1.70 [1.31-2.21], and 1.36 [1.18-1.57], respectively). However, after adjusting for cardiovascular risk factors and prevalent cancer alongside age, sex, and CMV, immune cell phenotypes were no longer associated with mortality in our cohort. Nonetheless, IL-6 remained significantly associated with all-cause and cardiovascular mortality (HRs: 1.3 [1.13-1.49], 1.5 [1.12-1.99], respectively). CONCLUSIONS: In 19-year follow-up, higher Tc17/CD8 + Treg and CD4/CD8 ratios were associated with lower all-cause mortality, while the CD8 + CD25 + FoxP3 + (CD8 + Treg) phenotype showed increased risk. Elevated IL-6 levels consistently correlated with amplified mortality risks. These findings highlight the links between immune phenotypes and mortality, suggesting implications for future research and clinical considerations.
