Age and sex differences in the association between Dietary Inflammatory Index and severe headache or migraine: a nationwide cross-sectional study.

BACKGROUND: Migraine and severe headaches are extremely prevalent neurological disorders that plague humans and society. Prior research has revealed that DII may affect the occurrence of migraines, but there are too few relevant studies and more are required. This study aimed to determine the association between severe headache or migraine and the Dietary Inflammatory Index (DII), with particular attention to age and gender differences. METHODS: Using data from the National Health and Nutrition Examination Survey (NHANES), we performed a cross-sectional study. In addition, we investigated the association between DII and severe headache or migraine using weighted multivariate logistic regression models, and restricted cubic splines models were plotted to explore their linear correlation. RESULTS: There were a total of 13,439 people participating in the study, and of those, 2745 experienced a severe headache or migraine within the previous three months. The DII was linearly and positively correlated with severe headache or migraine (odds ratio [OR] = 1.05, 95% confidence interval [CI] = 1.01-1.08, p = 0.0051). Stratified analysis showed that this relationship persisted among women and those aged < 60 years, with ORs of 1.08 (95% CI = 1.04-1.13, p = 0.0004) and 1.05 (95% CI = 1.01-1.09, p = 0.0071), respectively. CONCLUSIONS: We found that greater levels of DII were significantly related to an increased likelihood of migraine onset, especially among women and young and middle-aged populations. Further research is required to validate and expand upon our results.

WeChat Continuity Nursing on Postpartum Depression and Quality of Life in Primipara Undergoing Cesarean Delivery.

Objective: To assess the effectiveness of WeChat-based continuity nursing in reducing postpartum depression and improving the quality of life among primiparous women undergoing cesarean delivery. Methods: A total of 200 patients who intended to undergo cesarean delivery in our hospital between January 2021 and January 2022 were recruited for this study, including 20 patients who refused to participate in the study and 30 patients who did not meet the criteria of this study for various reasons, and a total of 150 cases were finally included. All participants were assigned 1:1 into the control group and observation group according to the time of the first pregnancy test and the primiparous in the observation group were given WeChat continuity nursing, and the primiparous in the control group was given routine obstetric care. WeChat continuity nursing included establishment of continuity nursing team, WeChat group setup and communication, education and support, and psychological counseling and follow-up. The baseline data of all mothers were collected and recorded, and the Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS), quality of life scores, maternal and infant complications, and the satisfaction rate of care were compared between the two groups. Results: The SAS and SDS scores of the observation group were consistently lower than those of the control group at 1, 3, and 6 months post-hospital discharge (P < .01). Following the implementation of WeChat continuity nursing intervention, patients in the observation group demonstrated significant improvements in mental health, physical function, somatic pain, vitality, and social function scores compared to the control group (P < .01). Additionally, the incidence of complications was notably lower in the observation group, including reduced rates of incisional infection, breast swelling, unclear dew, abnormal defecation among mothers, and decreased occurrence of breech redness, umbilical cord issues, eczema, and delayed umbilical cord detachment among infants (P < .05). Moreover, the satisfaction rate among patients in the observation group was significantly higher than that of the control group (95.507% vs. 84.058%) (P < .05). These findings highlight the efficacy and importance of integrating WeChat continuity nursing intervention into postpartum care practices. Conclusion: Our study strongly supports the effectiveness of WeChat continuity nursing intervention in improving postpartum mental health, reducing complications, and increasing patient satisfaction. These findings suggest the potential for integrating digital nursing interventions into standard postpartum care practices, offering personalized and accessible healthcare services. Policymakers and healthcare providers should consider adopting such interventions to optimize postpartum outcomes and enhance patient experiences.

A new perspective on hippocampal synaptic plasticity and post-stroke depression.

Post-stroke depression, a common complication after stroke, severely affects the recovery and quality of life of patients with stroke. Owing to its complex mechanisms, post-stroke depression treatment remains highly challenging. Hippocampal synaptic plasticity is one of the key factors leading to post-stroke depression; however, the precise molecular mechanisms remain unclear. Numerous studies have found that neurotrophic factors, protein kinases and neurotransmitters influence depressive behaviour by modulating hippocampal synaptic plasticity. This review further elaborates on the role of hippocampal synaptic plasticity in post-stroke depression by summarizing recent research and analysing possible molecular mechanisms. Evidence for the correlation between hippocampal mechanisms and post-stroke depression helps to better understand the pathological process of post-stroke depression and improve its treatment.

Relationship Between Changes in Cranio-Cervical Extensor Muscles and Quality of Life: A Single-Center Study of 15 Patients with Chronic Tension-Type Headache.

BACKGROUND This single-center study of 15 patients with chronic tension-type headache aimed to compare the cranio-cervical extensor muscles between patients with chronic tension-type headache and healthy individuals and to explore the relationship between changes in cranio-cervical extensor muscles and quality of life (QoL). MATERIAL AND METHODS We recruited 15 patients with chronic tension-type headache and 15 healthy individuals. Patients with chronic tension-type headache were diagnosed by 2 neurologists according to the diagnostic criteria in the International Classification of Headache Disorders, 3rd edition (ICHD-3). Morphological changes in the cranio-cervical extensor muscle were detected using magnetic resonance imaging (MRI). QoL and the degree of neck dysfunction were assessed using the Headache Impact Test-6 (HIT-6) and Neck Disability Index (NDI), respectively. RESULTS The relative cross-sectional areas (rCSAs) of the rectus capitis posterior minor (RCPmin) were lower in patients with chronic tension-type headache than in healthy individuals. The HIT-6 scores (r=-0.93, P<0.001 and r=-0.85, P<0.001 for RCPmin right side and left side, respectively) and NDI scores (r=-0.75, P<0.001 and r=-0.70, P<0.001 for RCPmin right side and left side, respectively) were negatively associated with the rCSA of RCPmin in the chronic tension-type headache group. CONCLUSIONS Most patients with chronic tension-type headache experience RCPmin atrophy. The more evident the RCPmin atrophy, the worse the QoL of the patients with chronic tension-type headache.

Early swallowing training after free flap surgery in oral cancer: A randomized controlled trial.

OBJECTIVE: To explore the effect of early swallowing training on postoperative outcomes of patients who had undergone oral cancer surgery plus free flap reconstruction. SUBJECTS AND METHODS: In this prospective, randomized controlled trial, 121 patients who had undergone oral cancer surgery plus free flap reconstruction were randomly assigned to the control (n = 59) or intervention group (n = 62). The control group underwent routine nursing measures. The intervention group received swallowing training on the sixth postoperative day. On the 15th day and 1 month after surgery, the swallowing function (Mann Assessment of Swallowing Ability-Oral Cancer [MASA-OC] score), weight loss rate, time of nasogastric tube removal, and quality of life were evaluated. RESULTS: Patients in the intervention group had higher MASA-OC scores and better weight loss rates than those in the control group on the 15th day (MASA-OC: p = 0.014, weight loss: p < 0.001) and 1 month (both p < 0.001) after surgery. The time of nasogastric tube removal and the quality of life was statistically significant between groups (p < 0.001). CONCLUSION: Early swallowing training improves the swallowing function, nutritional status, and quality of life and shortens the indwelling time of nasogastric tube of patients who have undergone oral cancer surgery plus free flap reconstruction.

A Resting-State Functional Magnetic Resonance Imaging Study of Abnormal Frontoparietal Network Function in Migraine without Aura.

BACKGROUND This study aimed to investigate frontoparietal network (FPN) dysfunction in participants with migraine without aura (MwoA). MATERIAL AND METHODS We selected 48 age-, sex-, and education level-matched graduate students (24 participants with MwoA [MwoA group] and 24 healthy controls). RS-fMRI and independent component analysis were used to examine the FPN and to compare abnormal encephalic regional homogeneity values. The Mindful Attention Awareness Scale (MAAS), Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), and Self-Rating Scale of Sleep (SRSS) were used to evaluate attention, anxiety, depression, and sleep, respectively. Pearson's correlation was applied to evaluate the association between abnormal brain areas and the scores for each scale. RESULTS Neural function activity in encephalic regions of FPN showed abnormal changes in the MwoA group. The MwoA group had significantly lower MAAS scores (P<0.001), higher SAS scores (P<0.001), and higher SDS (P=0.06) and SRSS scores (P=0.26). In the MwoA group, functional activity of the right parietal lobule in the left FPN was positively correlated with MAAS scores (P=0.01) and negatively correlated with SAS (P=0.02). The orbital part of left inferior frontal gyrus activity in the right FPN was positively correlated with SDS (P=0.04) and SRSS (P<0.001). Right superior marginal gyrus activity in the right FPN was positively correlated with SDS (P=0.02). CONCLUSIONS Abnormal FPN function was correlated with attention, anxiety, depression, and sleep status in the MwoA group. These results offer further insights into the evaluation and treatment of MwoA.

A Systematic Review of Swallowing Training Measures for Postoperative Oral Cancer Patients.

Swallowing disorder is one of the most common postoperative complications for oral cancer patients and seriously influences quality of life. Limited attention has been paid to evaluating swallowing training measures in postoperative oral cancer patients. This study systematically reviewed swallowing training measures for these patients. A comprehensive search strategy was undertaken across various databases for studies published between database inception and 15 June 2021. Raters independently judged titles, abstracts and full articles for selection according to inclusion and exclusion criteria. The included literature was evaluated for quality and data were extracted. Meta-analyses were conducted using RevMan 5.3. Ten intervention studies (four randomized controlled trials and six quasi-experimental studies) involving 588 patients were identified. Across the studies, most started in the early postoperative stage; however, there were differences in starting time, training time and duration, and type of training. We summarized four training methods: oral exercise, oral sensory stimulation, compensatory strategies and protective airway manoeuvres. The meta-analysis indicated that swallowing training could improve patients' swallowing function and quality of life in the short term, but the long-term effects were not obvious. Swallowing training mostly occurred in the early postoperative period and training measures were often used in combination. The timing, frequency and content of interventions varied between studies, and the effectiveness of any single measure was unclear. High-quality randomized controlled trials are necessary to study the efficacy and clinical applicability of various training measures, to provide a theoretical basis for their optimal selection and to develop a standardized training programme for postoperative oral cancer patients.

Differences in network centrality between high and low myopia: a voxel-level degree centrality study.

BACKGROUND: Previous studies have linked high myopia (HM) to brain activity, and the difference between HM and low myopia (LM) can be assessed. PURPOSE: To study the differences in functional networks of brain activity between HM and LM by the voxel-level degree centrality (DC) method. MATERIAL AND METHODS: Twenty-eight patients with HM (10 men, 18 women), 18 patients with LM (4 men, 14 women), and 59 healthy controls (27 men, 32 women) were enrolled in this study. The voxel-level DC method was used to assess spontaneous brain activity. Correlation analysis was used to explore the change of average DC value in different brain regions, in order to analyze differences in brain activity between HM and LM. RESULTS: DC values of the right cerebellum anterior lobe/brainstem, right parahippocampal gyrus, and left caudate in HM patients were significantly higher than those in LM patients (P < 0.05). In contrast, DC values of the left medial frontal gyrus, right inferior frontal gyrus, left middle frontal gyrus, and left inferior parietal lobule were significantly lower in patients with HM (P < 0.05). However, there was no correlation between behavior and average DC values in different brain regions (P < 0.05). CONCLUSION: Different changes in brain regions between HM and LM may indicate differences in neural mechanisms between HM and LM. DC values could be useful as biomarkers for differences in brain activity between patients with HM and LM. This study provides a new method to assess differences in functional networks of brain activity between patients with HM and LM.

Hsa-miR-877-5p Expression in Acute Ischemic Stroke Based on Bioinformatics Analysis and Clinical Validation.

Inflammation and immunity play important roles in the pathogenesis of ischemic stroke. This study aimed to explore key regulatory genes in acute ischemic stroke (AIS) and their underlying mechanisms to provide new research targets for the diagnosis and treatment of ischemic stroke. We searched for differentially expressed mRNAs and miRNAs in patients with AIS and healthy populations in GEO databases, constructed a miRNA-mRNA network, and screened key miRNAs using least absolute shrinkage and selection operator regression and the support vector machine-recursive feature elimination model. Correlations between key miRNAs and infiltrating immune cells and inflammatory factors were analyzed using CIBERSORT and immunoassays and verified using clinical experiments. Bioinformatics analysis identified hsa-miR-877-5p as a key regulatory miRNA in AIS that can modulate immune and inflammatory responses. In clinical studies, it was verified by quantitative PCR analysis that the expression of hsa-miR-877-5p in the blood of AIS patients was higher than that of the healthy group. Then, enzyme-linked immunosorbent assay revealed that the expression of IL-23 and TNF-α related to inflammation in AIS patients was higher than that of the healthy. Quantitative PCR further found that the relative mRNA expression of IL-23, CXCR3, and TNF-α in AIS group was higher than that of the healthy group. This study may provide a basis for a more comprehensive understanding of the potential mechanism of the occurrence and development of AIS, and hsa-miR-877-5p and its downstream effectors IL-23, CXCR3, and TNF-α may be potential intervention targets in AIS.

Silicone oil migrating into the conjunctival space and orbit after surgery for an eye-penetrating injury: A case report.

BACKGROUND: We report a case of eye-penetrating injury in which a massive silicone oil migration into the patient's subconjunctival space and orbit occurred after vitrectomy. CASE SUMMARY: A 30-year-old male patient sought medical attention at Ganzhou People's Hospital after experiencing pain and vision loss in his left eye due to a nail wound on December 9, 2023. Diagnosis of penetrating injury caused by magnetic foreign body retention in the left eye and hospitalization for treatment. On December 9, 2023, pars plana vitrectomy was performed on the left eye for intraocular foreign body removal, abnormal crystal extraction, retinal photocoagulation. Owing to the discovery of retinal detachment at the posterior pole during surgery, silicone oil was injected to fill the vitreous body, following which upper conjunctival bubble-like swelling was observed. Postoperative orbital computed tomography (CT) review indicated migration of silicone oil to the subconjunctival space and orbit through a self-permeable outlet. On December 18, 2023, the patient sought treatment at the First Affiliated Hospital of Nanchang University, China. The patient presented with a pronounced foreign body sensation following left eye surgery. On December 20, 2023, the foreign body was removed from the left eye frame and an intraocular examination was conducted. The posterior scleral tear had closed, leading to termination of the surgical procedure following supplementary laser treatment around the tear. The patient reported a significant reduction in ocular surface symptoms just one day after surgery. Furthermore, a notable decrease in the migration of silicone oil was observed in orbital CT scans. CONCLUSION: The timing of silicone oil injection for an eye-penetrating injury should be carefully evaluated to avoid the possibility of silicone oil migration.

Looking for a Beam of Light to Heal Chronic Pain.

Chronic pain (CP) is a leading cause of disability and a potential factor that affects biological processes, family relationships, and self-esteem of patients. However, the need for treatment of CP is presently unmet. Current methods of pain management involve the use of drugs, but there are different degrees of concerning side effects. At present, the potential mechanisms underlying CP are not completely clear. As research progresses and novel therapeutic approaches are developed, the shortcomings of current pain treatment methods may be overcome. In this review, we discuss the retinal photoreceptors and brain regions associated with photoanalgesia, as well as the targets involved in photoanalgesia, shedding light on its potential underlying mechanisms. Our aim is to provide a foundation to understand the mechanisms underlying CP and develop light as a novel analgesic treatment has its biological regulation principle for CP. This approach may provide an opportunity to drive the field towards future translational, clinical studies and support pain drug development.

Early swallowing intervention after free flap reconstruction for oral cancer: A systematic review and meta-analysis.

OBJECTIVES: This study aimed to summarize the state of current literature and evaluate evidence for timing, methods, and effects of early intervention in patients after free flap reconstruction. METHODS: A comprehensive search was conducted in nine databases. The methodological quality of literature was assessed according to the JBI Critical Appraisal Tools. RESULTS: Eight studies were finally included. Most studies started the intervention within 1 to 2 weeks after surgery with multiple swallowing training measures. The results of meta-analysis showed that swallowing intervention could improve swallowing function (SMD = -1.03, 95%CI [-1.37, -0.69], Z = 5.95, p < 0.01) and the quality of life (SMD = 1.52, 95%CI [0.97, 2.07], Z = 5.43, p < 0.01). CONCLUSION: Early swallowing intervention can improve patients' swallowing function and short-term quality of life. We can only summarize the basic consensus of the studies on early swallowing intervention, and rigorous trials are needed in the future.

Rhabdomyolysis-induced acute kidney injury after administration of a red yeast rice supplement: A case report.

BACKGROUND: A few reports have revealed induction of rhabdomyolysis by a red yeast rice (RYR) supplement or by RYR in combination with abiraterone (an androgen biosynthesis inhibitor). CASE SUMMARY: A 76-year-old man presented with progressive limb weakness, muscle soreness, and acute kidney injury (AKI). He had been taking the anti-prostate cancer drug abiraterone for 14 mo and had added a RYR supplement 3 mo before symptom onset. After being diagnosed with rhabdomyolysis-induced AKI, the patient discontinued these drugs and responded well to hemodialysis and hemoperfusion. After 23 d of treatment, creatine kinase levels returned to normal and serum creatinine levels decreased. CONCLUSION: We speculate that statins, the main lipid-lowering component of RYR, or a combination of statins and abiraterone, will increase the risk of rhabdomyolysis.

The role of T cells in acute ischemic stroke.

Acute ischemic stroke (AIS) is associated with high rates of disability and mortality, exerting a substantial impact on overall survival and health-related quality of life. Treatment of AIS remains challenging given that the underlying pathologic mechanisms remain unclear. However, recent research has demonstrated that the immune system plays a key role in the development of AIS. Numerous studies have reported infiltration of T cells into ischemic brain tissue. While some types of T cells can promote the development of inflammatory responses and aggravate ischemic damage in patients with AIS, other T cells appear to exert neuroprotective effects via immunosuppression and other mechanisms. In this review, we discuss the recent findings regarding the infiltration of T cells into ischemic brain tissue, and the mechanisms governing how T cells can facilitate tissue injury or neuroprotection in AIS. Factors influencing the function of T cells, such as intestinal microflora and sex differences, are also discussed. We also explore the recent research on the effect of non-coding RNA on T cells after stroke, as well as the potential for specifically targeting T cells in the treatment of stroke patients.

Association Between Copper Intake and Migraine: a National Cross-sectional Study.

Migraine is a common clinical neurological disorder that adversely affects humans and society. The relationship between copper intake and migraine has been less studied and controversial. The purpose of this study was to determine the relationship between copper intake and migraine and to guide dietary interventions. The data for this study were obtained from the National Health and Nutrition Examination Survey (NHANES) database from 1999 to 2004, involving a total of 12,724 participants. The relationship between copper intake and migraine was examined using weighted multivariate logistic regression models, and smooth-fit curves were plotted to explore the relationship. After non-linear relationships were found, recursive algorithms and two-stage linear regression models were used to calculate inflection points. Stratified analyses were also performed to explore population differences. In the model corrected for all covariates, the OR (95% CI) of copper intake with migraine was 1.19 (0.97, 1.46), which was not statistically significant. However, the results of the linear trend test suggested that their relationship might be non-linear. Smooth-fit curves confirmed the non-linear relationship between copper intake and migraine, and an inflection point (0.98 mg/day) was identified. There was no statistical significance before the inflection point, but after the inflection point, copper intake was positively associated with migraine attacks. Stratified analyses showed that this non-linear relationship persisted in females, people under 45 years old, and people with BMI less than 30. In this large cross-sectional study, we found a non-linear correlation between copper intake and migraine.

The piRNA pathway is required for nucleopolyhedrovirus replication in Lepidoptera.

The Piwi-interacting RNA (piRNA) pathway has been shown to be involved in the antiviral defense against RNA viruses, especially in mosquitoes, but its universality has been questioned. Here, we used the Bombyx mori nucleopolyhedrovirus (BmNPV) -infected silkworm as a model to explore the effects of the key factors of piRNA pathway, BmAgo3 and Siwi, on replication of a large DNA virus (belonging to the family of Baculoviridae). We demonstrated that BmAgo3 and Siwi could promote the replication of BmNPV through both overexpression and knockdown experiments in BmN cell lines and silkworm larvae. In addition, we also studied the effect of PIWI-class genes on Autographa californica nucleopolyhedrovirus (AcMNPV) replication in the Spodoptera frugiperda cell line Sf9. By knocking down the expression of PIWI-class genes in Sf9, we found that Piwi-like-1 and Piwi-like-2-3 could inhibit AcMNPV replication, while Piwi-like-4-5 promoted virus replication. Our study provides compelling evidence that the piRNA pathway affects host infection by exogenous viruses in Lepidoptera. Also, our results reflect the diversity of the roles of PIWI-class genes in virus infection of the host across species. This study is the first to explore the interaction of PIWI-class proteins with DNA viruses, providing new insights into the functional roles of the piRNA pathway.

Timing of Oral Feeding in Patients Who have Undergone Free Flap Reconstruction for Oral Cancer.

OBJECTIVE: Determine the safety and effectiveness of a nasogastric tube removal plan designed to shorten nasogastric tube indwelling time after oral cancer surgery plus free flap reconstruction. MATERIALS AND METHODS: A parallel randomized clinical trial was conducted from May 2021 to December 2021 at Peking University School of Stomatology. Volunteers (n = 128) were separated into four groups: non-tracheostomy control and intervention groups and tracheostomy control and intervention groups. Control patients received the conventional nasogastric tube removal plan. Non-tracheotomy intervention patients were asked to swallow 5 ml of water on the first postoperative day. If there was no coughing, they were allowed progressively increasing amounts of water for the following 2 days. The nasogastric tube was removed only after ensuring level I/II performance on the Watian water swallowing test, no "wet voice" after drinking water, no marked decrease in blood oxygen saturation after drinking, and satisfactory daily oral nutritional intake. Tracheotomy intervention patients received the same protocol plus an additional Watian water swallowing test after tracheal tube removal. RESULTS: Nasogastric tube removal time was earlier in the intervention subgroups than in control subgroups: 5.0 ± 2.3 days versus 7.8 ± 3.9 days (p = 0.001) in non-tracheostomy patients and 9.8 ± 1.1 days versus 16.2 ± 13.0 days (p = 0.049) in tracheostomy patients. Incidence of wound complications and daily food intake were comparable between the groups. The incidence of pneumonia was lower in the tracheostomy intervention group than in the tracheostomy control group (12.5% vs. 3.1%, p = 0.162). Pharyngeal pain score was lower in tracheotomy intervention patients than in tracheotomy control patients (p = 0.029). Postoperative hospital stay was shorter in tracheotomy intervention patients than in tracheotomy control patients (p = 0.005). CONCLUSIONS: On the basis of ensuring safety and effectiveness, patients undergone free flap reconstruction for oral cancer could be offered oral intake early after surgery, which will not increase the incidence of wound complications and pneumonia or adversely affecting the oral intake of the patients; it can also help minimize pharyngeal pain and shorten postoperative hospital stay of patients with a tracheotomy. LEVEL OF EVIDENCE: 2 Laryngoscope, 133:1382-1387, 2023.

BmCH25H, a vertebrate interferon-stimulated gene(ISG) homolog, inhibits BmNPV infection dependent on its hydroxylase activity in Bombyx mori.

Cholesterol-25-hydroxylase (CH25H) has been identified as an interferon-stimulated gene (ISG) in mammals that exerts its antiviral effects by catalyzing the conversion of cholesterol to 25-hydroxycholesterol (25HC). However, invertebrates lack an antiviral system homologous to vertebrate interferons (IFNs) because the genomes of invertebrates do not encode IFN-like cytokines. Nevertheless, CH25H is present in insect genomes and it therefore deserves further study of whether and by which mechanism it could exert an antiviral effect in invertebrates. In this study, the Bombyx mori CH25H (BmCH25H) gene, of which the encoded protein has high homology with other lepidopteran species, was identified and located on chromosome 9. Interestingly, we found that the expression of BmCH25H was significantly upregulated in B. mori nucleopolyhedrovirus (BmNPV) -infected BmN cells and silkworm (B. mori) larvae at the early infection stage. The inhibitory effect of BmCH25H on BmNPV replication was further demonstrated to depend on its catalytic residues to convert cholesterol to 25HC. More importantly, we demonstrated that during BmNPV infection, BmCH25H expression was increased through the Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway, similar to the induction of ISGs following virus infection in vertebrates. This is the first report that CH25H has antiviral effects in insects; the study also elucidates the regulation of its expression and its mechanism of action.

Tongmai Zhuke decoction restrains the inflammatory reaction of macrophages for carotid artery atherosclerosis by up-regulating lincRNA-Cox2.

To explore the mechanism of Tongmai Zhuke decoction for promoting blood circulation by taking carotid artery atherosclerosis (CAA) as an example, two sets of in-depth transcriptomic data as well as two sets of single-cell RNA sequencing data related to the macrophages in CAA were included. STAR and DCC software were used to process in-depth transcriptomic data in order to measure the expression level of LncRNAs as well as mRNA according to FPKM analysis. Single-cell RNA sequencing data from Illumina NovaSeq 6000 were further analyzed by CellRanger channel, CellRanger count, Seurat R package, DoubletFinder package, CCA algorithm, LogNormalize, principal-component analysis, t-SNE and ToppGene online tools. Based On unsupervised clustering, a total of four diverse cell populations with distinct transcriptional features were found in human carotid atherosclerotic plaques. The macrophages were further annotated as the "effector cell" in the pathologic process of CAA, based on the expression of CD68+/CD440-. A total of 84 up-regulated genes and 58 down-regulated linc-RNAs were identified in samples with carotid atherosclerotic plaques. Thereinto, lincRNA-Cox2 is the most down-regulated LincRNA. For the macrophages in carotid atherosclerotic plaques, expression level of Il6, Ccl3, Ccl4 Il10 and Tnfa were significantly up-regulated, while Timp1 significantly down-regulated comparing with healthy carotid sample. The expression level of lincRNA-Cox2 was significantly increased in macrophages after treated by Tongmai Zhuke decoction, while Cxcl10, Ccl3, Ccl4, Cxcl2, Ccl5, and Ccl19 were significantly decreased. Collectively, Tongmai Zhuke decoction could restrain the inflammatory reaction of macrophages for carotid artery atherosclerosis by up-regulating lincRNA-Cox2.
