Abstract
The apolipoprotein E (APOE) ε4 is a well-established risk factor of amyloid-β (Aβ) in Alzheimer's disease (AD). However, because of the high prevalence of APOE ε3, there may be a large number of people with APOE ε3/ε3 who are non-demented and have Aβ pathology. There are limited studies on assessing Aβ status and clinical conversion in the APOE ε3/ε3 non-demented population. Two hundred and ninety-three non-demented individuals with APOE ε3/ε3 from ADNI database were divided into Aβ-positron emission tomography (Aβ-PET) positivity (+) and Aβ-PET negativity (-) groups using cut-off value of >1.11. Stepwise regression searched for a single or multidimensional clinical variables for predicting Aβ-PET (+), and the receiver operating characteristic curve (ROC) assessed the accuracy of the predictive models. The Cox regression model explored the risk factors associated with clinical conversion to mild cognitive impairment (MCI) or AD. The results showed that the combination of sex, education, ventricle and white matter hyperintensity (WMH) volume can accurately predict Aβ-PET status in cognitively normal (CN), and the combination of everyday cognition study partner total (EcogSPTotal) score, age, plasma p-tau 181 and WMH can accurately predict Aβ-PET status in MCI individuals. EcogSPTotal score were independent predictors of clinical conversion to MCI or AD. The findings may provide a non-invasive and effective tool to improve the efficiency of screening Aβ-PET (+), accelerate and reduce costs of AD trial recruitment in future secondary prevention trials or help to select patients at high risk of disease progression in clinical trials.

Abstract
The coexistence of ferroptosis and other modes of death has great advantages in the treatment of cancers. A series of glutathione peroxidase 4 (GPX4) and cyclin-dependent kinase (CDK) dual inhibitors were designed and synthesized, given the synergistic anticancer effect of ML162 (GPX4 inhibitor) in combination with indirubin-3'-oxime (IO) (CDK inhibitor). Compound B9 exhibited the highest potential cytotoxic activity against all four cell lines and displayed excellent inhibitory activity against GPX4 (IC50 = 542.5 ± 0.9 nM) and selective inhibition of CDK 4/6 (IC50 = 191.2 ± 8.7, 68.1 ± 1.4 nM). Mechanism research showed that B9 could simultaneously induce ferroptosis and arrest cells at the G1 phase in both MDA-MB-231 cells and HCT-116 cells. Compared with ML162 and IO, B9 showed much stronger cancer cell growth inhibition in vivo. These results proved that developing potent GPX4/CDK dual inhibitors is a promising strategy for the malignant cancer therapy.

Abstract
BACKGROUND Dysregulated cell death machinery and an excessive inflammatory response in Coxsackievirus B3(CVB3)-infected myocarditis are hallmarks of an abnormal host response. Complement C4 and C3 are considered the central components of the classical activation pathway and often participate in the response process in the early stages of virus infection. METHODS In our study, we constructed a mouse model of CVB3-related viral myocarditis via intraperitoneal injection of Fer-1 and detected myocarditis and ferroptosis markers in the mouse myocardium. Then, we performed co-IP and protein mass spectrometry analyses to explore which components interact with the ferroptosis gene transferrin receptor (TFRC). Finally, functional experiments were conducted to verify the role of complement components in regulating ferroptosis in CVB3 infection. RESULTS It showed that the ferroptosis inhibitor Fer-1 could alleviate the inflammation in viral myocarditis as well as ferroptosis. Mechanistically, during CVB3 infection, the key factor TFRC was activated and inhibited by Fer-1. Fer-1 effectively prevented the consumption of complement C3 and overload of the complement product C4b. Interestingly, we found that TFRC directly interacts with complement C4, leading to an increase in the product of C4b and a decrease in the downstream complement C3. Functional experiments have also confirmed that regulating the complement C4/C3 pathway can effectively rescue cell ferroptosis caused by CVB3 infection. CONCLUSIONS In this study, we found that ferroptosis occurs through crosstalk with complement C4 in viral myocarditis through interaction with TFRC and that regulating the complement C4/C3 pathway may rescue ferroptosis in CVB3-infected cardiomyocytes.

Abstract
AIMS The aims of the study were to explore the experiences of women with gestational diabetes mellitus (GDM) and their partners and examine the factors influencing partner involvement in GDM management, seeking to inform a targeted couple-based intervention. DESIGN A descriptive qualitative study. METHODS We conducted semi-structured interviews with 14 women with GDM and their partners. Participants were recruited through convenience sampling from a tertiary hospital in Xi'an, China. Data were analysed using thematic analysis. RESULTS Three themes and 12 subthemes were identified. Theme I: Women's expectations of their partner's involvement in GDM management-practical support and emotional support. Theme II: Partner involvement in GDM management-constructive involvement, unhelpful involvement with good intentions and insufficient involvement. Theme III: Factors that influence partner involvement in GDM-knowledge of GDM, GDM risk perception, health consciousness, attitudes towards the treatment plan, couple communication regarding GDM management, family roles and appraisal of GDM management responsibility. CONCLUSION Women desired practical and emotional support from partners. The types of partner involvement in GDM management varied. Some partners provided constructive support, while some partners' involvement was limited, non-existent or actively unhelpful. By combining these results with the factors influencing partner involvement, our findings may help healthcare professionals develop strategies to involve partners in GDM care and enhance women's ability to manage GDM. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE Partner involvement in GDM care may help them understand and better attend to women's needs, thus improving their experience and potential outcomes. This study highlights novel factors that need to be considered in developing couple-based interventions for this population. REPORTING METHOD The reporting follows the COREQ checklist. PATIENT OR PUBLIC CONTRIBUTION Some patients were involved in data interpretation. There is no public contribution.

Abstract
Viral myocarditis (VMC) is the major reason for sudden cardiac death among both children and young adults. Of these, coxsackievirus B3 (CVB3) is the most common causative agent of myocarditis. Recently, the role of signaling pathways in the pathogenesis of VMC has been evaluated in several studies, which has provided a new perspective on identifying potential therapeutic targets for this hitherto incurable disease. In the present study, in vivo and in vitro experiments showed that CVB3 infection leads to increased Bim expression and triggers apoptosis. In addition, by knocking down Bim using RNAi, we further confirmed the biological function of Bim in apoptosis induced by CVB3 infection. We additionally found that Bim and forkhead box O1 class (FOXO1) inhibition significantly increased the viability of CVB3-infected cells while blocking viral replication and viral release. Moreover, CVB3-induced Bim expression was directly dependent on FOXO1 acetylation, which is catalyzed by the co-regulation of CBP and SirTs. Furthermore, the acetylation of FOXO1 was an important step in Bim activation and apoptosis induced by CVB3 infection. The findings of this study suggest that CVB3 infection induces apoptosis through the FOXO1 acetylation-Bim pathway, thus providing new insights for developing potential therapeutic targets for enteroviral myocarditis.

Abstract
Objective: To analyze the immunological characteristics and antibody changes of patients infected with the Omicron BA.1 and evaluate the possibility of secondary infection. Methods: A total of 104 patients infected with Omicron BA.1 in the Jinnan District of Tianjin from January 8 to February 2, 2022, were included in the study. The control group and case group were matched 1∶1 based on age, sex and vaccination status. Serum was collected from the case group and control group at 3, 6 and 9 months after infection. The serum levels of interleukin4 (IL-4), IL-5 and interferon-gamma (IFN-γ), as well as the positive rates of IgG, IgG1 and IgG2, were detected by ELISA. Results: The highest concentration of IFN-γ in the case group at 6 months after infection was 145.4 pg/ml, followed by a decrease in concentration. The concentrations of IL-4 and IL-5 began to decrease at 6 months after infection (all P<0.001). There was no significant difference in the IgG2 positive rate between the case group and the control group at 6 months after BA.1 infection. However, at 9 months, there was a significant decrease compared to the control group (P=0.003). The ratio of IFN-γ/IL4 at 3 months after infection in the case group was lower than that in the control group (P<0.001). There was no significant difference in the ratio between the case group and the control group at 9 months after infection. Conclusion: The cellular immune function has been impaired at 3 months after infection with BA.1, and the specific cellular immune and humoral immune functions decrease significantly after 6 months, and the risk of secondary infection increases.

Abstract
Glutathione peroxidase 4 (GPX4) is an essential antioxidant enzyme that negatively regulates ferroptosis. To exploit novel GPX4 inhibitors, we designed and synthesized 32 indirubin derivatives. Compound 31 exhibited the strongest antitumor activity against HCT-116 cells (IC50 = 0.49 ± 0.02 μM). Further studies suggested that 31 could induce ferroptosis in colon cancer cells and its cytotoxic activity could be reversed by ferroptosis inhibitors. Mechanism research showed that 31 promoted the degradation of GPX4, causing the accumulation of lipid ROS to induce ferroptosis. Animal experiments also proved that 31 could inhibit the growth of colon cancer cells in vivo and reduce the expression of GPX4 in tumor tissues. These results indicated that compound 31 had potential as a novel ferroptosis inducer agent for colon cancer.

Abstract
PURPOSE To investigate the incidence of fear of cancer recurrence (FCR) in Chinese postmastectomy patients and explore the relationships between metacognition, coping style, and FCR on the basis of the self-regulating executive function model. METHODS A total of 480 postmastectomy patients from two tertiary comprehensive hospitals in Xi'an were enrolled from March 2021 to November 2021. The participants completed demographic information, the Metacognitions Questionnaire-30 (MCQ-30), Positive Metacognitions and Positive Meta-Emotions Questionnaire (PMCEQ), Simplified Copying Style Questionnaire (SCSQ), and Fear of Cancer Recurrence Inventory Short Form (FCRI-SF). RESULTS 34.2% of the respondents had scores indicating a clinical level of FCR (FCRI-SF≥13). FCR had a positive correlation with maladaptive metacognition and negative coping style (P < 0.01), while adaptive metacognition and positive coping style were negatively correlated (P < 0.01). Besides, maladaptive metacognition had both direct and indirect effects on FCR, with the indirect effect primarily mediated by negative coping style (total effect, 0.430). Adaptive metacognition had both direct and indirect effects on FCR, with the indirect effect primarily mediated by positive coping style (total effect,﹣0.302). CONCLUSION FCR was a common phenomenon in postmastectomy patients and moderate in most patients. In addition, both metacognition and coping style had a direct and indirect association with the occurrence and development of FCR. Moreover, adaptive metacognition and maladaptive metacognition had different mechanisms on FCR in patients with breast cancer.

Abstract
Due to its complex pathological mechanisms, bone cancer pain (BCP) has become an increasingly challenging clinical issue, there is an urgent need to identify the underlying mechanisms of BCP. In our present study, we found that decreased expression of miR-199a-3p in spinal dorsal horn (SDH) neurons contributed to BCP hypersensitivity. Intrathecal administration of miR-199a-3p agomir alleviated the initiation of tumor inoculation induced pain hypersensitivity and suppressed the expression of DNMT3A. Subsequently, luciferase assays confirmed direct binding between miR-199a-3p and Dnmt3a mRNA. AAV-DNMT3A-shRNA microinjection relieved mechanical hyperalgesia and upregulated the expression of Nrf2 levels in BCP. In naïve rats, Overexpression of DNMT3A yielded the opposite effects. Finally, increase of DNMT3A by lentiviral vector abolished miR-199a-3p-mediated alleviation hypersensitivity effects on BCP progression. Taken these together, our findings highlighted a novel contribution of miR-199a-3p to BCP and provided a fresh outlook on potential mechanism research for BCP.

Abstract
AIMS To estimate the effectiveness of the Couples Coping with Gestational Diabetes Mellitus (GDM) Programme on GDM self-management and pregnancy outcomes. METHODS A randomised controlled trial among pregnant women with suboptimal GDM self-management and their partners was undertaken. Couples recruited from three hospitals in China were randomly allocated to either intervention (n = 70) or control (n = 70) conditions. Couples in the intervention group underwent the couple-based intervention (GDM education, shared illness appraisals, initiation of collaborative action and consolidation of collaborative action). Women in the control group received individual GDM education. Data were analysed using the independent samples t-test, chi-square test, and generalised estimating equations. RESULTS GDM knowledge for the women and their partners and GDM self-management significantly improved in both the intervention and control groups, with stronger improvement in the intervention group. Women in the intervention group gained significantly less weight than those in the control group (11.2 kg ± 2.8 kg vs 13.1 kg ± 2.6 kg, p = 0.008). Infant birth weights were significantly lower in the intervention group (3.2 kg ± 0.3 kg vs 3.4 kg ± 0.4 kg, p = 0.008). There were no significant differences in other pregnancy outcomes. CONCLUSIONS The Couples Coping with GDM Programme was associated with improvements in GDM knowledge of women and their partners and in women's self-management, and with lower gestational weight gain and infant birth weight.

Abstract
1. A study was conducted to evaluate the effects of dietary cholecalciferol (vitamin D3) and 25-hydroxycholecalciferol (25-OH-D3) supplementation on the reproductive performance, egg quality, eggshell ultrastructure, serum hormone level and antioxidant capacity, intestinal morphology and tibia quality of breeder geese during the laying period.2. The trial was designed as a 3 × 3 factorial arrangement with three levels (300, 400 and 500 IU/kg) of vitamin D3 supplementation and three levels (25, 50 and 75 μg/kg) of 25-OH-D3 supplementation in a 10-wk feeding trial.3. The results showed that the combined supplementation of 400 IU/kg vitamin D3 and 50 μg/kg 25-OH-D3 had a better feed conversion ratio and a higher egg laying rate than the other groups. Vitamin D3 supplementation significantly increased the rate of qualified eggs for hatching, eggshell strength and thickness, serum testosterone and progesterone levels, serum total superoxide dismutase and glutathione peroxidase activities, tibia ash content and bone mineral density (P < 0.05). Dietary 25-OH-D3 supplementation significantly increased serum glutathione peroxidase activity and duodenal villus height and villus height-to-crypt-depth ratio (P < 0.05). The geese receiving 500 IU/kg vitamin D3 and 75 µg/kg 25-OH-D3 had the highest tibia calcium and phosphorous content among all groups (P < 0.05).4. Feeding 400 IU/kg vitamin D3 plus 50 µg/kg 25-OH-D3 gave optimal effects on feed conversion ratio and egg laying rate. This combination could be a nutritional strategy for increasing the laying rate, eggshell quality, serum hormone levels and serum antioxidant function regardless of 25-OH-D3 supplementation. Supplementation of 50 μg/kg 25-OH-D3 could be a recommended dose for improving the serum antioxidant capacity and intestinal morphology regardless of vitamin D3 supplementation.

Abstract
Objective: To investigate the clinical effects of the bow-tie adjustable suture technique in managing overcorrection in patients with intermittent exotropia after surgery. Methods: This was a retrospective case series study. Clinical data were collected from children with intermittent exotropia who underwent strabismus correction surgery, including the bow-tie adjustable suture technique and conventional techniques, at the Department of Strabismus and Pediatric Ophthalmology, Shanxi Eye Hospital, from January 2020 to September 2021. Children with postoperative esodeviation≥15 prism diopters (PD) within the first 6 days were treated differently based on the surgical technique and their individual conditions, including suture adjustment and conservative treatment. The overcorrection rate and its changes among different surgical groups, the recovery of ocular alignment and binocular visual function after different treatment methods in children with overcorrection on the sixth postoperative day, and the postoperative complications in different surgical groups were observed. Statistical analysis was performed using independent samples t-test, Wilcoxon rank-sum test, repeated-measures analysis of variance, Bonferroni test, chi-square test, or Fisher's exact probability test, as appropriate. Results: A total of 643 children who underwent intermittent exotropia correction surgery were included in the study. Among them, 325 children underwent the bow-tie adjustable suture technique, with 185 males and 140 females, and the mean age was (9.50±2.69) years. The remaining 318 children underwent conventional techniques, with 176 males and 142 females, and the mean age was (9.90±2.67) years. There were no statistically significant differences in age and gender distribution between the two surgical groups (all P>0.05). On the first postoperative day, among children who underwent the bow-tie adjustable suture technique, 40 had an esodeviation of≥10 PD, resulting in an overcorrection rate of 12.3% (40/325), while among children who underwent conventional techniques, 32 had an esodeviation of≥10 PD, resulting in an overcorrection rate of 10.1% (32/318). On the sixth postoperative day, these rates decreased to 5.5% (18/325) and 3.1% (10/318) in the two groups, respectively. At 1, 6, and 12 months postoperatively, the overcorrection rate in children who underwent the bow-tie adjustable suture technique was 0, while in children who underwent conventional techniques, the overcorrection rate did not show a significant decrease compared to before surgery. The differences between the two surgical groups were statistically significant (all P<0.05). On the sixth postoperative day, among children with an esodeviation of≥15 PD, 13 underwent suture adjustment and 7 received conservative treatment. The results of repeated-measures analysis of variance showed statistically significant differences in near and distance esodeviation angles among children who received different treatment methods (F=145.20, 106.87, both P<0.001), as well as statistically significant differences in near and distance esodeviation angles at different time points within each group of children (F=81.67, 35.09, both P<0.001). There were also significant differences in the trends of change in near and distance esodeviation angles at different time points among children who received different treatment methods (F=79.90, 36.73, both P<0.001). Further pairwise comparisons showed significant differences in near and distance esodeviation angles between the sixth postoperative day and 1, 6, and 12 months postoperatively in children who underwent suture adjustment (all P<0.05), while no statistically significant differences were observed in children who received conservative treatment (all P>0.05). At 12 months postoperatively, among the 13 children who underwent suture adjustment, 12 achieved stereopsis, while among the 7 children who received conservative treatment, all became stereo-blind after removing the prismatic correction. No serious complications occurred in any of the children postoperatively. Conclusion: The proportion of children with intermittent exotropia who achieved orthotropic alignment one year after surgery was relatively low among those who had an overcorrection of≥15 PD on the sixth postoperative day. The bow-tie adjustable suture technique is a simple and effective approach for managing overcorrection in patients with intermittent exotropia. Adjusting the sutures on the sixth postoperative day can reduce the overcorrection rate and is considered a safe and effective method.

Abstract
BACKGROUND The way to evaluate brain tau pathology in vivo is tau positron emission tomography (tau-PET) or cerebrospinal fluid (CSF) analysis. In the clinically diagnosed mild cognitive impairment (MCI), a significant proportion of tau-PET are negative. Interest in less expensive and convenient ways to detect tau pathology in Alzheimer's disease has increased due to the high cost of tau-PET and the invasiveness of lumbar puncture, which typically slows down the cost and enrollment of clinical trials. OBJECTIVE We aimed to investigate one simple and effective method in predicting tau-PET status in MCI individuals. METHODS The sample included 154 individuals which were dichotomized into tau-PET (+) and tau-PET (-) using a cut-off of >1.33. We used stepwise regression to select the unitary or combination of variables that best predicted tau-PET. The receiver operating characteristic curve was used to assess the accuracy of single and multiple clinical markers. RESULTS The combined performance of three variables [Alzheimer's Disease Assessment Scale-Cognitive Subscale 13 (ADAS-Cog13), Mini-Mental State Examination (MMSE), ADNI-Memory summary score (ADNI-MEM)] in neurocognitive measures demonstrated good predictive accuracy of tau-PET status [accuracy = 85.7%, area under the curve (AUC) = 0.879]. The combination of clinical markers model (APOEɛ4, neurocognitive measures and structural MRI imaging of middle temporal) had the best discriminative power (AUC = 0.946). CONCLUSION As a noninvasive test, the combination of APOEɛ4, neurocognitive measures and structural MRI imaging of middle temporal accurately predicts tau-PET status. The finding may provide a non-invasive, cost-effective tool for clinical application in predicting tau pathology among MCI individuals.

Abstract
OBJECTIVES Cerebral venous sinus thrombosis (CVST) due to adenomyosis, though rare, threaten women with severe morbidity. Adenomyosis is easily overlooked in the etiological assessment of CVST. Etiological under-recognization has considerable prognostic, and therapeutic implications. The current study reports two cases of successful management of cerebral venous sinus thrombosis due to adenomyosis. MATERIALS AND METHODS We present two young women with cerebral venous sinus thrombosis due to adenomyosis. We additionally review the literature to identify previously reported cases of stroke associated with adenomyosis. RESULTS Except for this report, a total of 25 cases of stroke related to adenomyosis have been reported in the literature, of which only three cases are related to CVST. Through their diagnosis and treatment, we believe that early diagnosis and treatment are important for these patients with long-term illnesses. In addition, through literature review, for female stroke patients with heavy menstruation combined with anemia or carbohydrate antigen (CA) 125 elevation, the existence of adenomyosis should be vigilant and the etiological treatment should be timely targeted. CONCLUSION Our cases illustrate the significance of the etiological identification of CVST for women with adenomyosis and serve to increase clinicians' awareness of this disabling, but sometimes treatable, condition. In CVST due to adenomyosis associated with iron deficiency anemia and/or high serum CA125 level, antithrombotic therapy and treatment for the anemia may improve the hypercoagulable state. The long-term monitoring of D-dimer levels is required.

Abstract
OBJECTIVES The prognosis of patients with locally advanced esophageal squamous cell carcinoma with different recurrence backgrounds is highly heterogeneous. This study aims to explore the effects of recurrence patterns on prognosis. METHODS The phase III, multicenter, prospective NEOCRTEC5010 trial enrolled 451 patients with stage IIB-III esophageal squamous cell carcinoma randomly assigned to neoadjuvant chemoradiotherapy combined with surgery (NCRT group) or surgery alone (S group) and followed them long-term. We investigated the effects of recurrence patterns on survival in patients undergoing radical esophagectomy. RESULTS In total, 353 patients were included in the study. The 5-year overall survival of patients with different recurrence patterns was significantly different: recurrence versus recurrence-free (17.8% vs 89.2%; P < .001), early recurrence versus late recurrence (4.6% vs 51.2%; P < .001), and distant metastasis versus locoregional recurrence (17.0% vs 20.0%; P = .666). Patients with early recurrence had significantly shorter survival after recurrence than those with late recurrence (hazard ratio, 1.541; 95% confidence interval, 1.047-2.268, P = .028). There was no significant difference in postrecurrence survival between patients with distant metastasis and locoregional recurrence (hazard ratio, 1.181; 95% confidence interval, 0.804-1.734; P = .396). Multivariate logistic analysis showed that pN1 stage, lymph node dissection <20, and lack of response to NCRT were independent risk factors for postoperative early recurrence. Multivariate Cox regression suggested that NCRT, age ≥60 years, early recurrence, and the pN1 stage were independent risk factors for shortened survival after recurrence. CONCLUSIONS Prerecurrence primary tumor stage is inaccurate in predicting postrecurrence survival. In contrast, recurrence patterns can guide follow-up while also predicting postrecurrence survival. NCRT prolongs disease-free survival but is associated with a worse prognosis in patients with recurrence, especially early recurrence.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Qixue Shuangbu Prescription (QSP) is a classical traditional Chinese medicine prescription, which has widely used for the treatment of chronic heart failure (CHF). Preliminary clinical studies have shown that the efficacy of processed QSP (P-QSP) in treating CHF is greater than crude QSP (C-QSP). However, the pharmacokinetic characteristics of its major bioactive components under pathological conditions are unclear. AIM OF STUDY This study aims to compare pharmacokinetics of seven bioactive components after oral administration of C-QSP and P-QSP in CHF model rats. MATERIALS AND METHODS Ginsenoside Rb1, ginsenoside Re, ginsenoside Rg1, ferulic acid, astragaloside IV, calycosin-7-O-β-D-glucoside, and paeoniflorin in QSP were used as the target components. CHF model in rats was induced by the intraperitoneal injection of doxorubicin. A microdialysis combined with UPLC-MS/MS method was first established to compare the pharmacokinetics of seven major bioactive components in CHF model rats after oral administration of C-QSP and P-QSP. RESULTS This method was successfully applied to the pharmacokinetic investigation of seven major components of C-QSP and P-QSP following oral administration in CHF model rats. Compared with the C-QSP group, the Cmax, AUC0-t and AUC0-∞ of ginsenoside Rb1, ginsenoside Re, ginsenoside Rg1, ferulic acid, astragaloside IV and paeoniflorin significantly increased (P < 0.05) in the P-QSP group, which suggested that the absorptivity and bioavailability were increased. Lower T1/2, MRT0-t of ginsenoside Rb1, gerulic acid and higher T1/2, MRT0-t of ginsenoside Rb1, astragaloside IV, paeoniflorin in the P-QSP group, which indicated that eliminated more quickly or slowly, respectively. CONCLUSIONS The pharmacokinetic parameters of bioactive components were significantly changed for better bioavailability and absorption, longer lasting time elimination, which were beneficial for enhancing therapeutic efficacy in the P-QSP group. This study will provide a new perspective to explain the pharmacokinetic-pharmacodynamic correlation of P-QSP on the treatment of CHF.

Abstract
SQSTM1/p62 sequesters intracellular aberrant proteins and mediates their selective autophagic degradation. p62 oligomerization posttranslational modification enhances its sequestration function and positively regulates the KEAP1-NRF2 redox pathway. However, the regulation of p62 covalent oligomerization has yet been poorly characterized. Here, we identified a natural small-molecule sesquiterpene, Iso-seco-tanapartholide (IST) modified p62 cysteine residues, which induced p62 to form crosslinked oligomers between TBS and TBS or TBS and PB1 domains in a covalently non-disulfide-linked manner. Using LC-MS/MS analysis and complementary approaches, we revealed that Cys residues of p62 were necessary for IST-induced covalent oligomer. This oligomerization promoted p62 recruitment of KEAP1 for degradation by autophagosomes and released NRF2 to the nucleus to activate the expression of downstream genes with anti-oxidant and anti-inflammatory capacities. Accordingly, IST-mediated p62/NRF2 activation conferred protection from oxidative and inflammatory destruction of rheumatoid arthritis in vitro and in vivo. In contrast, p62-knockdown cells displayed a reduced anti-oxidant response and increased pro-inflammatory cytokine secretion in response to TNF-α stimulation. Hence, our findings uncover an unrecognized role of IST in the regulation of p62 oligomerization and provide a new strategy for the treatment of rheumatoid arthritis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In traditional Chinese folk medicine, Artemisia argyi H.Lév. & Vaniot (A. argyi) has been used for thousands of years, and it is clinically used to treat bronchitis and asthma. However, the mechanism of action of A. argyi on respiratory tract inflammation is not clear. Accumulating evidence that phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3) is actively expressed in inflammation. Here, we found that iso-seco-tanapartholide (IST), a sesquiterpene isolated from A. argyi, exhibited potent anti-inflammatory activity and significant inhibition of PFKFB3 expression. Therefore, we evaluated the effect of IST on airway inflammation and revealed its possible mechanisms. AIM OF THE STUDY This study aimed to investigate the protective effect and possible mechanism of IST in lipopolysaccharide (LPS)-induced acute lung injury in mice. MATERIALS AND METHODS In vitro, RAW264.7 cells and BMDMs were stimulated with LPS, and the level of NO and inflammatory factors TNF-α, IL-1β, and IL-6 were detected by Griess reagent and ELISA, respectively. The effect of IST on the levels of PFKFB3 and its downstream proteins (p-STAT3, p-p65) in cells was assayed by western blotting. Lactate and glycolytic phenotypes were detected by lactate kit and Seahorse assay. In vivo, a mouse model of acute lung injury was induced by LPS, and the levels of inflammatory factors were measured by ELISA. Expression of PFKFB3 and its downstream proteins (p-STAT3, p-p65) in mouse alveolar macrophages by western blotting analysis. Lung permeability assessment by Evans Blue dye assay. H&E staining and Immunocytochemistry were used to observe the protection of IST against lung injury. RESULTS IST significantly reduced LPS-induced expression of PFKFB3 and its downstream proteins (p-STAT3, p-p65). The inhibition of PFKFB3 has an impact on the glycolytic phenotype, such as a reduction in the rate of extracellular acidification (ECAR) and elevated lactate levels, and an increase in the rate of cellular oxygen consumption (OCR). Furthermore, IST inhibited LPS-induced NO release and increased the expression of pro-inflammatory factors TNF-α, IL-1β, and IL-6. In vivo, IST reduced pulmonary edema in LPS-induced acute lung injury, improved lung function, and reduced levels of inflammatory factors and lactate secretion. CONCLUSIONS These results suggest that IST improves the characteristics of ALI by inhibiting the expression of the PFKFB3-mediated glycolytic pathway and may be a potential anti-inflammatory agent for inflammation-related lung diseases.

Abstract
BACKGROUND Human coronaviruses (HCoVs) are important respiratory pathogens in humans and animals. Most HCoVs are emerging pathogens, with five known human pathogens identified in the last two decades. AIM To examine the clinical course of HCoV infection in children to improve understanding of severity and outcomes. METHODS A retrospective review was undertaken of all encounters of children with known HCoV infection at a tertiary paediatric hospital from January 2015 to January 2018. Electronic medical records were reviewed for demographic data, HCoV type, viral co-pathogens, time to testing, need for hospitalization, requirement for higher-level care (HLC) including intensive care unit management and requirement for oxygen support, radiographic findings suggestive of lower respiratory tract (LRT) disease, and length of stay (LOS). FINDINGS In total, 450 encounters for 430 different patients were identified, with the majority (85%) being inpatient. OC43 was the most common HCoV. Younger patients (age <5 years) had higher probability of hospitalization [adjusted odds ratio (aOR) 2.2, 95% confidence interval (CI) 1.2-4.1], requirement for HLC (aOR 1.8, 95% CI 1.0-3.1) and presence of LRT findings on chest radiographs (aOR 1.7, 95% CI 1.01-2.9). Clinical outcomes did not differ between HCoV types, except LOS which was longer for 229E. Fifty-two (11%) encounters were detected after 3 days of hospitalization (median 25.5 days), suggesting possible nosocomial infection. CONCLUSION HCoVs are important respiratory pathogens in the paediatric population, especially among patients aged <5 years who are at increased risk for severe disease. The role of HCoVs as hospital-acquired pathogens may be underappreciated.

Abstract
BACKGROUND This study evaluates the impact of general anesthesia combined with erector spinae plane blocks (ESPB) on patients who underwent thoracoscopic radical resection (TRR) for lung cancer. METHODS There involved a total of 108 patients undergoing TRR for lung cancers. Patients enrolled were equally allocated into experimental group (general anesthesia combined with ESPB) and control group (general anesthesia). The following parameters, including baseline characteristics, serum markers of neurological disorders, postoperative pain degree, dosage of narcotic, adverse events and early postoperative rehabilitation quality, were compared between the two groups. RESULTS Based on Visual Analogue Scale, the postoperative pain degree was significantly lower in experimental group on 6h postoperative (P<0.001). And markedly lower results were observed in the levels of serum markers of neurological disorders in the experimental group one day after surgery (all P<0.05). Moreover, the dosage of narcotic and early postoperative rehabilitation quality based on QoR-40 scale were significantly lower in experimental group (all P<0.05). CONCLUSION Adding ESPB with general anesthesia reduce the postoperative pain up to 6 h, reduce the requirement of postoperative narcotic and help early postoperative rehabilitation quality.

Abstract
Introduction TSG-6 plays a wide anti-inflammatory and therapeutic role in a variety of autoimmune diseases as the key mediator of mesenchymal stem cells (MSCs). Purpose We aimed to test whether TSG-6 could exert similar effects as MSCS in TAO via establishing TAO animal model immunized by hTSHR-A subunit plasmid. Material and Methods We tested the expression level of TSG-6 on intraconal orbital fat from controls and patients with TAO. We established a stable thyroid-associated ophthalmopathy animal model by immunizing 6-week-old female Balb/c mice with recombination hTSHR-A subunit plasmid. After four immunizations, TSG-6 or dexamethasone was injected through the tail vein. The effects of the drugs on body weight, thyroid function, orbital inflammation, fibrosis and lipogenesis were observed. Results The expression of TSG-6 in the orbital tissues of TAO patient is lower than that of normal people. In our animal model, mice showed weight loss, higher TT4 and TSHR antibody levels, and ocular symptoms such as inflammation and proptosis. TSG-6 can reduce ocular fibrosis and lipogenesis by inhibiting the infiltration of CD3+ T lymphocytes and macrophages in the mouse model of thyroid associated ophthalmopathy. Compared with dexamethasone, TSG-6 showed comparable anti-inflammatory effect, moreover, it has given a better performance in inhibiting adipogenesis. Conclusion It was demonstrated that TSG-6 has a considerable positive impact on improving eye symptoms of TAO mice, which could be a novel candidate for the early treatment of TAO.

Abstract
Coxsackievirus B3 (CVB3) is a leading cause of viral myocarditis, but no effective treatment strategy against CVB3 is available. Viruses lack an inherent metabolic system and thus depend on host cellular metabolism for their benefit. In this study, we observed that CVB3 enhanced glycolysis in H9c2 rat cardiomyocytes and HL-1 mouse cardiomyocytes. Therefore, three key glycolytic enzymes, namely, hexokinase 2 (HK2), muscle phosphofructokinase (PFKM), and pyruvate kinase M2 (PKM2), were measured in CVB3-infected H9c2 and HL-1 cells. Expression levels of HK2 and PFKM, but not PKM2, were increased in CVB3-infected H9c2 cells. All three key glycolytic enzymes showed elevated expression in CVB3-infected HL-1 cells. To further investigate this, we used 2 deoxyglucose, sodium citrate, and shikonin as glycolysis inhibitors for HK2, PFKM, and PKM2, respectively. Glycolysis inhibitors significantly reduced CVB3 replication, while the glycolysis enhancer dramatically promoted it. In addition, glycolysis inhibitors decreased autophagy and accelerated autophagosome degradation. The autophagy inducer eliminated partial inhibition effects of glycolysis inhibitors on CVB3 replication. These results demonstrate that CVB3 infection enhances glycolysis and thus benefits viral replication.

Methods We used two clinical POP datasets with patients' information (GSE12852 and GSE53868), a dataset consisting of altered microRNA expression in circulating blood after exercise (GSE69717) for bioinformatic analysis and clinical diagnostic analysis, while a series of cellular experiments were conducted for preliminary mechanical validation. Results Our results show that AXUD1 is highly expressed in the smooth muscle of the ovary and is a key pathogenic gene in POP, while miR-133b is a key molecule in the regulation of POP by exercise-induced serum exosomes. The AUCs of AXUD1 for POP diagnosis were 0.842 and 0.840 in GSE12852 and GSE53868 respectively. At cut-off value = 9.627, the sensitivity and specificity of AXUD1 for predicating POP is 1.000 and 0.833 respectively for GSE53868, while at cut-off value = 3324.640, the sensitivity and specificity of AXUD1 for predicating POP is 0.941 and 0.812 separately for GSE12852. Analysis and experiments confirmed that miR-133b can directly regulate AXUD1. miR-133b mediated C2C12 myoblasts proliferation and inhibited hydrogen peroxide-induced apoptosis. Conclusions Our study proved that AXUD1 is a good clinical diagnostic indicator for POP and provided a theoretical basis for future prevention of POP through exercise and a potential target for intervention in muscle dysfunction.

Abstract
OBJECTIVES Diabetic nephropathy (DN) is one of the most common microvascular complications of diabetes mellitus. Oxidative stress resulting from high glucose promotes accumulation of ECM and development of DN. Activation of Nrf2 could attenuate oxidative stress and following accumulation of ECM. To find novel therapy for DN, we explored the effects of swinhoeic acid from Potentilla fragarioides on mesangial cells under high glucose and underlying mechanisms. METHODS CCK-8 and BrdU incorporation assays for survival of mesangial cells gave the concentration of swinhoeic acid in following investigations. ROS, MDA, SOD and CAT were determined. And ECM proteins and their upstream regulators TGF-β1 and CTGF were detected using ELISA assays. Activation of Nrf2 was explored by immunofluorescence staining together with luciferase reporter assay. To demonstrate the role of Nrf2 activation, siRNA interference was performed. And co-immunoprecipitation assay was used to elucidate swinhoeic acid affects the interaction between Keap1 and Nrf2. RESULTS Swinhoeic acid at 10 and 20 μM attenuated oxidative stress and accumulation of ECM in mesangial cells under high glucose. Itactivated Nrf2 in a Keap1-dependent manner, which was involved in its effects. CONCLUSION Swinhoeic acid ameliorates oxidative stress and accumulation of ECM resulting from high glucose in mesangial cells via activating Nrf2 in Keap1-dependent manner.

Abstract
Purpose This study aims to explore the post-discharge experience and needs of COVID-19 survivors. Methods A qualitative study was conducted. A total of 16 post-discharge COVID-19 patients aged 31–68 years were recruited. The semi-structured interviews were conducted by telephone one month after discharge and were analysed by Colaizzi’s 7-step method. Results The post-discharge experience of COVID-19 patients were classified into four categories and ten subcategories. Category I: physiological problems consisted of physical sequelae (such as fatigue, shortness of breath, sleep disorder, chest pain) and a lack of physical rehabilitation guidance. Category II: psychological issues included anxiety, depression, fear, and psychological trauma. Category III: social issues included social stigma and financial stress. Category IV: positive experience and change included gratitude to social support and cherishing life and family. Conclusions COVID-19 survivors urgently need guidance for physical rehabilitation and psychological growth, social support provisions, and protection from social stigma. The experience of COVID-19 survivors is significant for planning healthcare management systems and guiding public health prevention efforts.

Abstract
Abstract
INTRODUCTION
DSC-MRI perfusion methods are commonly used to evaluate both primary and metastatic brain cancer with the creation of maps of relative cerebral blood volume (rCBV). Recently, guidelines were established to ensure a standard DSC-MRI acquisition protocol that reduces inter-site variability. The purpose of this study was to initiate the determination of rCBV benchmark values using the DSC-MRI consensus protocol in treatment-naïve brain metastases.
METHODS
Patients from three sites with treatment-naïve, contrast-enhancing brain metastases on MRI were considered for inclusion in this retrospective study. The MRIs included pre- and post-contrast T1w(T1+C) images obtained after administration of gadolinium-based contrast agent (GBCA) (0.1 mmol/kg), which serves as the recommended preload for the DSC-MRI data collection. A 2nd GBCA dose (0.1 mmol/kg) was administered 40-60sec after the collection of baseline GRE-EPI images using recommended settings (FA=60o, TE/TR=30ms/1100-1250ms) for 120s. Calibrated pre/post T1w difference maps (dT1) were used for delineation of enhancing lesion, and standardized (calibrated) rCBV (sRCBV) created. Mean sRCBV for metastases were compared to normal appearing white matter (NAWM) and treatment-naive glioblastoma (GBM) from a previous study. Pairwise comparisons were performed using the Mann-Whitney nonparametric test.
RESULTS
N=52 patients with primary histology of lung (n=27); breast (n=6); skin (n=7); gastrointestinal (GI: n=3) and genitourinary (GU: n=9) cancers were included in comparison to GBM (n=31). The mean sRCBV for all metastases (1.77+/-1.05) is significantly lower (p=0.0003) than for GBM (2.67+/-1.34) but with both statistically greater (p< 0.0001) than NAWM (0.706+/-0.163). Individually, lung (1.47+/- 0.61), breast (2.275+/-0.87), skin (2.10+/-1.22), GI (1.91+/- 0.64) and GU (2.01+/-0.63) mean sRCBV are statistically greater than for NAWM.
CONCLUSION
Using the consensus DSC-MRI acquisition protocol confirms use of sRCBV to identify biologically active, treatment-naive brain metastases setting benchmark values for future applications.

Abstract
Bone cancer pain (BCP) is a clinically intractable mixed pain, involving inflammation and neuropathic pain, and its mechanisms remain unclear. CXC chemokine receptor 1 (CXCR1, IL-8RA) and 2 (CXCR2, IL-8RB) are high-affinity receptors for interleukin 8 (IL8). According to previous studies, CXCR2 plays a crucial role in BCP between astrocytes and neurons, while the role of CXCR1 remains unclear. The objective of this study was to investigate the role of CXCR1 in BCP. We found that CXCR1 expression increased in the spinal dorsal horn. Intrathecal injection of CXCR1 siRNA effectively attenuated mechanical allodynia and pain-related behaviors in rats. It was found that CXCR1 was predominantly co-localized with neurons. Intrathecal injection of CXCR1-siRNA reduced phosphorylated JAK2/STAT3 protein levels and the NLRP3 inflammasome (NLRP3, caspase1, and IL-1β) levels. Furthermore, in vitro cytological experiments confirmed this conclusion. The study results suggest that the spinal chemokine receptor CXCR1 activation mediates BCP through JAK2/STAT3 signaling pathway and NLRP3 inflammasome (NLRP3, caspase1, and IL-1β).

Abstract
Acute kidney injury (AKI) is a frequent and serious complication of sepsis, which results in a rapid decline of kidney function. Currently, there are no curative therapies for AKI. Theacrine is a purine alkaloid and exerts significant role in regulating inflammation, oxidative stress, and mood elevation. The study aims to evaluate the biological role and potential mechanism of theacrine in septic AKI. The murine and cellular models of septic AKI were established in lipopolysaccharide (LPS)-treated C57BL/6 mice and HK-2 cells, respectively. The effect of theacrine on alleviating septic AKI was assessed after pretreatment with theacrine in vivo and in vitro. We found that theacrine treatment significantly alleviated LPS-induced kidney injury, as evidenced by decreased levels of kidney injury markers (blood urea nitrogen and creatinine), inflammatory factors (IL-1β and IL-18), and cell apoptosis in vivo and in vitro. Mechanistically, theacrine markedly repressed the activation of NOD-like receptor (NLR) pyrin domain-containing protein 3 (NLRP3)inflammasome. As expected, MCC950 (a specific inhibitor of NLRP3) treatment also decreased LPS-induced production of IL-18 and IL-1β and cell apoptosis in HK-2 cells. More important, Nigericin sodiumsalt (a NLRP3 agonist) damaged the effect of theacrine on repressing kidney injury markers (blood urea nitrogen and creatinine), pro-inflammatory cytokines (IL-18 and IL-1β), and cell apoptosis. Taken together, these results demonstrate that theacrine alleviates septic AKI, at least in part by repressing the activation of NLRP3 inflammasome.

Abstract
Tuberculous infection in a skin wound is a rare but well-known condition. This study describes a child infected with tuberculosis after being wounded. Because of swelling and pain in his wrist tissue, he was admitted to the Affiliated Hospital of Jining Medical University of Shandong Province on 16 October 2021. His medical history only included a wound. He was discharged after debridement. The laboratory data were normal. Two months after surgery, his wound was still swollen and painful. Secretions from the wound were sent for metagenomic next-generation sequencing (mNGS), which revealed three reads related to the Mycobacterium tuberculosis complex group (MTBC). A diagnosis of cutaneous tuberculosis (TB) was made. The wound disappeared after anti-TB drugs were administered. This case demonstrates that, while TB presenting as a severe cutaneous wound is rare, it should be considered in the clinical diagnosis. Clinicians should also pay attention to extrapulmonary infection with MTBC in patients, particularly in some long-suffering patients, and identify the specific pathogen as soon as possible. mNGS could help to identify pathogens and facilitate early treatment, thereby improving the prognosis.

Abstract
Newcastle disease (ND) is an acute and highly contagious infectious disease found in poultry. Although commercial ND virus (NDV) vaccines are universally used, some case reports persistently documented vaccination failure. Therefore, novel strategies are still required to control the occurrence of the disease in chickens. Recently, nanobodies (Nbs), which have the advantages of small molecular weight and low production costs, have been shown to be promising therapeutics against viral infection. In the present study, a total of 16 Nbs against NDV nucleocapsid protein (NP) were screened from two libraries against NDV using phage display technology. Of the 16 screened Nbs, eight were prevented from binding to NDV NP protein through administering positive chicken sera for anti-NDV antibodies, indicating that the epitopes recognized by these eight Nbs were able to induce the immune response after the chickens were infected with NDV stock. Subsequently, transfection assay, construction of recombinant DF-1 cells capable of expressing different nanobodies and viral inhibition assay were used to screen the nanobodies inhibiting NDV replication. The results demonstrated that Nb18, Nb30, and Nb88 significantly inhibited the replication of Class I and different genotypes of Class II NDV strains in DF-1 cells when they were expressed in the cytoplasm. Collectively, these nanobodies provided new tools for researching the functions of NDV NP protein and may be used as a novel strategy for designing drugs against NDV infection in chickens.

Abstract
CVB3 is a single positive-strand enterovirus, and a common pathogen in myocarditis etiology. Although a number of antiviral candidates are under development, specific targeted therapy is not available for CVB3. Ferroptosis is a new type of regulatory cell death discovered in recent years. In this study, our team provided the first evidence that ferroptosis existed in CVB3 infection in vivo and in vitro by iron overload, and massive accumulation of lipid peroxides. Mechanistically, we construct a classical model of HeLa cells following a time-course infection (6, 12, 24, 36, 48 h) with CVB3 (MOI = 10). We demonstrated that the TFRC gene plays an important role in promoting ferroptosis in CVB3 infection and downregulation of TFRC attenuated the ferroptosis. Interestingly, we observed that TFRC was nuclear translocation induced by the CVB3, which was predominantly localized in the cell membrane, but redistributed to the nucleus during CVB3 infection. Moreover, we found that the transcription factor Sp1 was an essential factor that could bind to the TFRC promoter and upregulate the TFRC transcription. Collectively, these results suggest that the Sp1/TFRC/Fe axis may provide a new target for the development of therapies against CVB3 infection.

Background
Anatomical variations and characteristics of the left atrium (LA) may have a previously undescribed effect on source locations in atrial fibrillation (AF). Electrographic flow (EGF) mapping is a novel method used to estimate cardiac action potential flow in the atria that can detect AF sources in patients with persistent AF. The EGF technology offers a revolutionary mapping possibility for AF, however, it is not commercially available yet.
Purpose
This is the first study aiming to investigate the relationship between anatomical characteristics of the LA and non-PV sources detected by EGF in patients with persistent AF.
Methods
We collected cardiac computed tomography (CT) and EGF data from patients who underwent radiofrequency catheter ablation (CA) for persistent AF. EGF mapping creates a spatial and temporal reconstruction of electric potentials derived from endocardial unipolar electrograms. By analyzing EGF maps obtained during CA procedures, we localized non-PV sources in the LA. Patients with individual stable sources with a source activity above threshold (leading source present in more than > 26% of the time) were classified as having an S-Type EGF signature with source-dependent AF. Patients with no stable active source pattern and no leading source with a source activity above threshold were characterized as having a C-Type EGF signature consistent with source-independent AF. We assessed LA anatomical characteristics including size, LAA length, LAA ostial diameter, trajectory of the left superior pulmonary vein (LSPV) and its relation to the LAA on cardiac CT scans. Abutting LAA-LSPV was defined as cases when the LSPV touched the posterior aspect of LAA, and the maximal distance between the two structures was less than 2 mm. Those cases where the distance between LAA and LSPV was more than 2 mm were defined as non-abutting LAA-LSPV.
Results
Thirty patients were included in this study (mean age 62.4±6.8 years):23 patients had an S-Type EGF signature (77%), and 7 patients had a C-Type EGF signature (23%). We identified 10 patients with AF sources near the LA ridge, while twenty patients had no leading source near the LA ridge. LA anatomical characteristics, LAA length and ostial diameter showed no correlation with the presence of a leading source near the ridge. We described 19 patients with abutting LAA-LSPV, and 11 patients with non-abutting LAA-LSPV. Three out of 19 patients presented with a leading source near ridge in the abutting LAA-LSPV group, while 7 out of 11 patients presented with a leading source near ridge in the non-abutting LAA-LSPV group (p=0.01).
Conclusion
Our data suggests that non-abutting LAA-LSPV is associated with the presence of AF sources near the LA ridge.

Background
Electrographic flow (EGF) mapping detects and quantifies patterns of electrical wavefront propagation in the atrial myocardium from basket catheter recordings. However, no single catheter can map the entire endocardial surface simultaneously. Creating panoramic maps of the whole atrium may be possible by reconstructing multiple basket positions obtained within a few minutes of each other.
Purpose
Present a method of 3D reconstruction of EGF maps generated from individual basket recordings using QRS morphologies and CT anatomies.
Methods
EGF maps were generated from unipolar signals recorded over 1 minute from 64-pole basket catheters. QRS morphologies recorded by each individual electrode were used to train a neural network (NN) on the reconstruction of the basket geometries in 3D. The NN uses the similarities between QRS morphologies to represent multiple recordings in one coherent 3D space and spatially integrate phenomena across multiple recordings without any external navigation system.
Results
A basket catheter was placed in the superior vena cava of a chronic AF canine model. The catheter was manually pulled back in steps of 5mm under fluoroscopic supervision. After reconstruction of the 3D electrode positions, a successive displacement of 3.5±1.2mm per step was reproduced. We applied the proposed method on recordings of 18 patients where an EGF source was identified. Independently, an expert determined the source locations on a 3rd party navigation system, based on 10 predefined regions in the left atrium. In 83% of the cases, the proposed method projected the sources in the same or adjacent region.
Conclusion
Novel 3D reconstruction from QRS signatures enables integration of EGF maps from multiple basket recordings that can be aligned with CT anatomy. Due to the real-time EGF map acquisition, synthesizing maps from more than 1 basket position provides a more panoramic visualization of complex atrial flow patterns.

Abstract
Background Patients with malignant pleural effusion (MPE) are usually treated with an indwelling pleural catheter (IPC) or pleurodesis. However, most do not achieve a satisfactory control rate of pleural effusion and have poor prognosis. Distilled water has cytocidal effects of hypotonic shock and can result in the lysis of cancer cells which was used in surgery to eradicate cancer cells. However, there is no study focusing on the efficacy of intrapleural hyperthemic perfusion for MPE under video-assisted thoracoscopic surgery (VATS). This study explored the efficacy and safety of intrapleural hyperthermic perfusion (IHP) with distilled water in patients with MPE. Methods In this retrospective, single-arm trial, patients admitted to department of cardiothoracic surgery of Taizhou hospital and diagnosed with MPE caused by non-small cell lung cancer from January 2014 and December 2018 were included. The clinical characteristics including age, gender smoking history, Karnofsky score, volume of pleural effusion, TNM cancer stage, pathology, genetic test of patients were collected. Patients were treated with hyperthermic perfusion. The pleural cavity was perfused with 43.0 ℃ distilled water for 60 minutes under video-assisted thoracic surgery (VATS). The efficacy of treatment was defined as follows: (I) complete remission (CR; no recurrence of pleural effusion after IHP for at least four weeks); (II) partial remission (PR; pleural effusion was decreased by 50% and the condition lasted for 4 weeks; or (III) no remission (NR; no decrease in pleural effusion). Kaplan-Meier method with a log-rank test was used for survival analysis. Cox proportional hazards regression models were applied to perform univariate and multivariate analyses Results From January 2014 through December 2018, 30 patients with MPE caused by non-small cell lung cancer (NSCLC) were treated with hyperthermic perfusion. There were no serious reportable clinical complications associated with the procedure. The response rate was 96.7%, with 63.3% experiencing PR and 33.3% achieving CR. The overall survival (OS) ranged from 2 to 46 months. The median survival was 12 months. Conclusions IHP proved to be a feasible and safe strategy for patients with MPE in our study but it still needs to be verified with a larger, prospective and randomized trial in the future.

Abstract
PURPOSE We assessed the effectiveness of "timing it right" (TIR) applications in patients undergoing radiotherapy for head and neck cancer through a carefully designed TIR intervention program. The assessment in this study emphasized the impact of the TIR intervention on the unmet needs and psychological pain of patients with head and neck cancer at different stages of radiotherapy. METHODS In total, 140 radiotherapy patients were randomly recruited into two study groups: (1) the TIR intervention group received routine nursing follow-up and comprehensive nursing intervention based on TIR, and (2) the control group received routine nursing care. Assessments were conducted at baseline, before discharge, and 3 months and 6 months after discharge. The comprehensive needs and psychological pain of patients with radiotherapy were measured using the Comprehensive Needs Assessment Tool in Cancer for Patients (CNAT) and the Distress Thermometer (DT), respectively. A linear mixed model was applied to analyze the effects. RESULTS A total of 137 patients completed the study. Compared to the control group, the TIR group showed significant improvements in information needs, health and psychological problems, healthcare staff, physical symptoms, health facilities and services, religious/spiritual support, and psychological pain (F=8.503, p=0.004; F=1.896, p=0.003; F=12.422, p<0.001; F=9.634, p=0.001; F=7.310, p=0.006; F=1.684, p=0.009; F=1.692, p=0.041). In addition to practical support, the remaining indicators differed significantly by time point, group, and group-time interaction. CONCLUSIONS The patient support application based on TIR can effectively address unmet needs and improve psychological pain, supporting TIR as an effective psychological management and intervention strategy for radiotherapy patients in the early stage of long-term rehabilitation.

Abstract
BACKGROUND Traditional Chinese medicine (TCM) is a type of alternative medicine that has been widely utilized in the prevention and treatment of mental diseases such as schizophrenia, ADHD, Alzheimer's disease, and Tourette's syndrome (TS) in many countries. However, the evidence regarding TCM's effectiveness and safety in treating TS are conflicting. Therefore, the goal of the present study is to analyze and summarize the available literature related to the efficacy of TCM in the treatment of TIC disorders especially, TS. MATERIALS AND METHODS Relevant articles for the meta-analysis were searched using appropriate keywords from PubMed, MEDLINE, and CENTRAL databases. Event data for TCM for the treatment of TS in the control and intervention arms were determined from the RCTs, and Diagnostic odds ratio and risk of bias analysis were performed. Meta-analysis was performed using MedCalc software, and suitable parameters to assess heterogeneity were computed. RESULTS Twelve randomized clinical trials with a total of 1681 Tourette syndrome patients were included as per the inclusion criteria. The patient's clinical symptoms were improved to a greater extent, and the pooled diagnostic odds ratio (DOR) of 1.311 with a 95% confidence interval (CI) value ranging from 0.804 to 2.139 I2 value of 72.04 % was obtained. The pooled relative risk was 1.09, with a 95%CI value ranging from 0.97 to 1.268. The data heterogeneity was assessed, and we achieved the Q value of 33.54, p-value 0.0004, and I2 value of 67.21% with a 95% CI value of 32.91 to 82.10. All these values are statistically significant, with p <0.005, and confirmed the effectiveness of TCM for TICS patients Conclusion: The present meta-analysis on account of these statistically significant results highly recommends using traditional Chinese medicine (TCM) to treat Tourette syndrome.

Abstract
Objective: To investigate the short-term efficacy of the prism treatment in a manner of reducing prism diopters step by step for small-angle acute acquired concomitant esotropia (AACE). Methods: Retrospective case series study. The clinical data of 17 AACE patients with strabismus ≤25 prism degrees (PD) including 6 males and 11 females, aged 14 to 60 years, who underwent the prism treatment in the Strabismus and Pediatric Ophthalmology Clinic of Shanxi Eye Hospital from October 2018 to June 2020 were collected. The prism treatment was conducted by a step-by-step reduction of prism diopters. An under-corrected prism was applied to the patient for the first time, and the degree of the prism was reduced gradually with the decrease in the degree of strabismus. Statistical analysis was performed after 6 months of treatment. The treatment success was defined as obtaining orthotropia and deleting diplopia when prism glasses were weaned off. The strabismus degree, Worth 4 dot test results, near stereopsis (Titmus stereopsis) and synoptophore fusion function before and after treatment were compared, and the factors affecting the curative effect were analyzed. Statistical methods mainly included paired t-test, Wilcoxon rank sum test, the Fisher exact test and univariate logistic regression analysis. Results: Among these 17 patients, 15 had myopia and 2 had emmetropia. Pretherapeutic esodeviation was (13.94±5.83) PD at near (33 cm), and was (15.76±5.24) PD at distance (6 m). After 6 months of treatment, 7 patients were successfully cured. The deviation angle at distance [(10.60±7.16) PD] and near [(9.80±6.00) PD] of the remaining 10 patients at 6 months after prismatic treatment was significantly smaller than that before treatment [(17.50±5.40) PD and (16.10±5.47) PD; t=3.69, 4.10; both P<0.01]. The Titmus stereogram showed that 2 cases had no stereopsis, 6 cases had peripheral stereopsis, 3 cases had macular stereopsis, and 6 cases had foveal stereopsis before treatment. Stereopsis was significantly improved at 6 months after prismatic treatment, with 3 cases havimg macular stereopsis and 14 cases having foveal stereopsis (Z=-2.99; P<0.01). The Worth-4-dot test disclosed that, the number of patients who saw four lamps at distance and near was 0 and 2 before treatment, and 7 and 9 after treatment, respectively, and the difference was statistically significant (both P<0.05). The divergent fusional amplitude and convergent fusional amplitude in the synoptophore at 6 month after treatment was not significantly different from that before treatment (both P>0.05). The efficacy of treatment was not significantly related to the duration from onset to treatment, the pretherapeutic esodeviation, the Titmus stereoacuity, cycloplegic refractive error, and age (all P>0.05). None of the 7 patients, who were successfully cured had a recurrence of esotropia or diplopia during the observation period of 6 to 24 months (median, 11 months). Conclusions: Prism treatment in a manner of step-by-step reduction of prism diopters can significantly diminish the degree of esotropia and improve the binocular function in small-angle AACE. Furthermore, some patients could be cured, achieving orthophoria without diplopia.

Abstract
Covalent modification of Keap1 results in reducing ubiquitination and the accumulation of Nrf2, which subsequently initiates the transcription of cellular anti-oxidant and anti-inflammatory genes. Iso-seco-tanapartholide (IST), a sesquiterpene isolated from the traditional Chinese medicine Artemisia argyi, had been reported to possess NF-κB inhibitory activity. However, its deep anti-inflammatory effects and direct target have never been reported. Here we show that IST activated Nrf2 and increased its target gene expression. In particular, LPS-caused inflammation in vitro and in vivo was mitigated by IST-induced Nrf2 activation but aggravated by Nrf2 inhibition. Mechanically, IST targeted Keap1 proteins via alkylating its cysteine residues 151, 273, 288, and so on. Subsequently, the modifying agent IST was displaced by intermolecular sulfhydryl disulfide interchange to lead to a disulfide dimer of Keap1. The resulting conformational change of Keap1 liberated Nrf2 from sequestration and allowed it translocation to the nucleus to activate the transcriptional program. Further studies demonstrated that Keap1 dimer formation contributed to the anti-inflammatory effects of IST. Taken together, our findings reveal a new mechanism for Nrf2 activation and provide a potential lead compound to treat inflammatory diseases through targeting Keap1.

Abstract
BACKGROUND Kawasaki disease (KD) is an acute systemic vasculitis of unknown etiology. The rs8108402 C/T single nucleotide polymorphism (SNP) is located in the promoter region of miR-181-c/d gene and the intron of Nanos3 gene. The miR-181 family contributes to the pathogenesis of cardiovascular and inflammatory disorders, while Nanos3 is involved in DNA transcription regulation and cell proliferation. However, no studies have examined the association between miR-181c/d and Nanos3 polymorphisms and the susceptibility and progression of KD. OBJECTIVE The purpose of our study is to examine the association of miR-181c/miR-181d/Nanos3 gene locus rs8108402 C/T polymorphism with KD susceptibility, intravenous immunoglobulin (IVIG) responsiveness, and the development of coronary artery lesions (CAL). METHODS Peripheral blood specimens from 100 children with KD and 100 healthy children were collected. The polymorphism of rs8108402 C/T was detected using polymerase chain reaction-sequencing-based typing technique. RESULTS There were statistically significant differences in C and T allele frequency distributions between the KD group and healthy controls for the polymorphic site rs8108402 C/T (P = 0.002). The distribution of the genotypes CC, CT, and TT also presented statistical significant difference between the KD and control groups (P = 0.003). Compared to the rs8108402 C allele, the T allele was associated with increased KD susceptibility (OR = 2.080, 95% CI = 1.317∼3.283). However, there were no significant associations discovered between the rs8108402 C/T polymorphism and CAL formation or IVIG unresponsiveness in the study. CONCLUSION SNP rs8108402 C/T located in the miR-181c/d promoter and Nanos3 intronic region is associated with susceptibility to Kawasaki disease but not with the development of coronary artery lesions or IVIG unresponsiveness in Chinese children.

Abstract
The effects of zinc (Zn) and Bacillus subtilis (B. subtilis) on reproductive performance, egg quality, nutrient digestion, intestine morphology, and antioxidant capacity were explored in geese breeders. Geese breeders (n = 120, 46-wk of age) were randomly assigned into 6 groups with 4 replicates of 5 birds each (1 male and 4 female). Breeders were fed diets with 2 levels of B. subtilis (2.5 × 109 and 5 × 109 CFU/kg) crossed with three levels of Zn (25, 45, and 65 mg/kg) for duration of 10-wk. The results showed that the egg laying rate (P < 0.05), fertility rate (P < 0.01), hatchability rate (P < 0.05), yolk color (P < 0.05), and the retentions of crude protein (P < 0.05), ether extract (P < 0.05) and phosphorus of geese breeders were improved by dietary supplementation of 5 × 109 CFU/kg B. subtilis and 25 mg or 45 mg/kg Zn. The serum T-SOD (P < 0.05) was increased by 45 mg/kg Zn supplementation. The serum T-AOC (P < 0.05) and retention of Zn (P < 0.05) were increased by 5 × 109 CFU/kg B. subtilis supplementation. The birds fed with 5 × 109 CFU/kg B. subtilis and 25 mg or 45 mg/kg Zn showed improved villus length (P < 0.01) and villus length/ crypt depth (P < 0.01) in both the jejunum and ileum. In conclusion, the combination of B. subtilis and Zn may have synergistic effects on these parameters, and dietary inclusion of 5 × 109 CFU/kg B. subtilis and 45 mg/kg Zn is recommended for improving the reproductive performance of geese breeders.

Abstract
OBJECTIVE To explore the significance of CYP3A4 and CYP3A5 genetic polymorphisms in achieving personalized fentanyl application in patients undergoing thoracoscopic operation. METHODS This was a retrospective study. One hundred patients with lung cancer received thoracoscopic surgery operation under the conditions of general anesthesia. According to the results of individualized analgesia guided by CYP3A4/5 polymorphisms, the patients were assigned into three groups: group I (the wild-type homozygote, the induced dosage of fentanyl: 6 µg/kg, the background infusion rate of patient-controlled intravenous analgesia (PCIA): 2 mL/h), group II (the heterozygote, the induced dosage of fentanyl: 5 µg/kg, the background infusion rate of PCIA: 1.5 mL/h), and group III (the mutant homozygote, the induced dosage of fentanyl: 4 µg/kg, the background infusion rate of PCIA: 1 mL/h). The locking-time was 15 min. A visual analog scale (VAS) score less than 3 points suggested effective analgesia. The times of operation and recovery were examined. Surgical plethysmography index (SPI), blood glucose levels, VAS and bruggemann comfort scale (BCS) scores at different time points were recorded, respectively. Total consumption of fentanyl, the effective time of PCIA compression, and the incidence of adverse drug reactions were also recorded. RESULTS There were no statistical differences in SPI, blood glucose level, VAS, BCS scores and incidence of adverse reactions among the three groups. In term of intraoperative, postoperative fentanyl doses and the amount of effective PCA, significant differences were found among the groups (P < 0.05). CONCLUSION According to the genotype of CYP3A4/CYP3A5, an individualized application of fentanyl is feasible.

Abstract
BACKGROUND Few studies have exclusively investigated the value of pathological complete response (pCR), in esophageal squamous cell carcinoma (ESCC) patients, although it is a clinically significant parameter to evaluate the impact of neoadjuvant chemoradiotherapy (nCRT) on treatment outcome after surgery. The aim of our study was to explore the relationship between pCR after nCRT and survival among patients with local ESCC. METHODS All patients receiving nCRT followed by surgery in NEOCRTEC5010-trial (NCT01216527) were included. Non-pCR patients were classified into three subgroups: ypTanyN0M0, ypT0NanyM0 and ypTanyNanyM0. The Kaplan-Meier method with log-rank test was employed to evaluate disease-free survival (DFS) and overall survival (OS). Multivariate regression analysis was performed using a Cox proportional hazards model to identify clinicopathological parameters associated with pCR. RESULTS Among the 185 patients included, 80 (43.2%) achieved pCR after nCRT. The mean survival time of the pCR group was significantly longer than that of the non-pCR group (92.6 vs. 69.2 months; HR, 2.70; 95% CI: 1.48-4.92; P=0.001). The 5-year OS and DFS of the pCR group were 79.3% and 77% respectively, compared to 54.8% and 51.2%, respectively, in the non-pCR group. The results showed that the OS and DFS of the ypTanyN0M0 group were better than those of the ypT0NanyM0 group and the ypTanyNanyM0 group. We also found that the number of dissected lymph nodes and pCR were independent risk factors for DFS and OS rates. CONCLUSIONS pCR after nCRT is an important prognostic indicator of OS and DFS in patients with ESCC. In addition, lymph-node status could represent an important parameter in the prognostic evaluation of esophageal cancer patients.
