Abstract
Liposomes have been widely studied as drug carriers for clinical application, and the key issue is how to achieve effective delivery through targeting strategies. Even though certain cell-level targeting or EPR effect designs have been developed, reaching sufficient drug concentration in intracellular regions remains a challenge due to the singularity of functionality. Herein, benefiting from the unique features of tumor from tissue to cell, a dual-thermosensitive and dual-targeting liposome (DTSL) was creatively fabricated through fine microstructure tailoring, which holds intelligent both tissue-regulated active-to-passive binding and membrane-derived homologous-fusion (HF) properties. At the micro level, DTSL can actively capture tumor cells and accompany the enhanced HF effect stimulated by self-constriction, which achieves a synergistic promotion effect targeting tissues to cells. As a result, this first active-then passive targeting process makes drug delivery more accurate and effective, and after dynamic targeting into cells, the nucleus of DTSL undergoes further thermally responsive contraction, fully releasing internal drugs. In vivo experiments showed that liposomes with dual targeting and dual thermosensitive features almost completely inhibited tumor growth. Summarized, these results provide a reference for a rational design and microstructural tailoring of the liposomal co-delivery system of drugs, suggesting that active-to-passive dual-targeting DTSL can function as a new strategy for cancer treatment.

Abstract
The tricuspid valve is known as "the forgotten valve". Tricuspid regurgitation (TR) is a highly prevalent valvular heart disease. TR is often late in the course of the disease when it becomes symptomatic, often being a marker of late-stage chronic heart failure with a poor prognosis and high mortality rate at long-term follow-up. Despite the clear correlation between TR and mortality, most TR patients are under-treated. Neither pharmacologic nor surgical treatment demonstrates a significant survival benefit. Isolated tricuspid valve surgery has the highest mortality rate of all valve surgeries. Therefore, there is an urgent clinical need for minimally invasive therapies to meet the needs of patients with TR. In recent years, a variety of transcatheter tricuspid valve interventions representing less invasive alternatives to surgery have shown promising results, which bring hope to patients with severe TR. The purpose of this review is to provide a complete and updated overview on current transcatheter tricuspid valve interventions and clinical evidence.

Abstract
PURPOSE This study aimed to show the outcomes of isolated tricuspid valve replacement (ITVR) after left-sided valve surgery (LSVS). METHODS Patients who underwent ITVR after LSVS were divided into bioprosthetic tricuspid valve (BTV) and mechanical tricuspid valve (MTV) groups. Clinical data were collected and analyzed between groups. RESULTS 101 patients were divided into BTV (n = 46) and MTV (n = 55) groups. The mean ages of the BTV and MTV groups were 63.4 ± 8.9 and 52.4 ± 7.6 years, respectively (P <0.01). There was no significant difference in 30-day mortality (BTV 10.9% vs. MTV 5.5%), early postoperative complications, and long-term tricuspid valve (TV)-related adverse events between these two groups. New-onset renal insufficiency was an independent risk factor for early mortality. Survival rates in the BTV group were 94.8% ± 3.6%, 86.5% ± 6.5%, and 54.2% ± 17.6% and in the MTV group were 96.0% ± 2.8%, 79.0% ± 7.4%, and 59.4% ± 14.8% at 1, 5, and 10 years, respectively (P = 0.826). CONCLUSION The TV prosthesis selection in ITVR after LSVS seems to not affect 30-day mortality and early postoperative complications. Long-term survival and the occurrence of TV-related events were also comparable between these two groups.

Abstract
Objective: To explore the spatial autocorrelation and macro influencing factors of stroke mortality in Zhejiang Province in 2015-2020 and provide a scientific basis for stroke prevention and control strategy. Methods: The data on stroke death were obtained from Zhejiang Chronic Disease Surveillance System. The spatial distribution of stroke mortality was explored by mapping and spatial autocorrelation analysis. The spatial panel model analyzed the correlation between stroke mortality and socioeconomic and healthcare factors. Results: From 2015 to 2020, the average stroke mortality was 68.38/100 thousand. The standard mortality of stroke was high in the areas of east and low in the west, high in the south and low in the north. Moreover, positive spatial autocorrelation was observed (Moran's I=0.274-0.390, P<0.001). Standard mortality of stroke was negatively associated with per capita gross domestic product (GDP) (β=-0.370, P<0.001), per capita health expenditure (β=-0.116, P=0.021), number of beds per thousand population (β=-0.161, P=0.030). Standard mortality of ischemic stroke was negatively associated with per capita GDP (β=-0.310, P=0.002) and standard management rate of hypertension (β=-0.462, P=0.011). Standard mortality of hemorrhagic stroke was negatively associated with per capita GDP (β=-0.481, P<0.001), per capita health expenditure (β=-0.184, P=0.001), number of beds per thousand population (β=-0.288, P=0.001) and standard management rate of hypertension (β=-0.336, P=0.029). Conclusions: A positive spatial correlation existed between stroke mortality in Zhejiang Province in 2015-2020. We must focus more on preventing and controlling strokes in relatively backward economic areas. Moreover, to reduce the mortality of stroke, increasing the investment of government medical and health funds, optimizing the allocation of medical resources, and improving the standard management rate of hypertension are important measures.

Abstract
BACKGROUND The study aimed to evaluate the prognostic value of preoperative systemic inflammation response index (SIRI) for acute type A aortic dissection (ATAD) following open surgery. METHODS AND RESULTS Totally, 410 ATAD patients underwent open surgery from 2019 to 2021 were enrolled in the study. Among the patients, the in-hospital mortality was 14.4%. Cox regression (95%CI 1.033-1.114p < 0.001) and receiver operating characteristic curve analysis (AUC = 0.718, p < 0.001) demonstrated the prognostic role of SIRI for in-hospital mortality after surgery. The optimal cut-off value of SIRI for in-hospital mortality was identified as 9.43 by maximally selected Log-Rank statistics. The patients were divided into high SIRI group (SIRI ≥ 9.43) and low SIRI group (SIRI < 9.43)) after the linear inverse relationship between SIRI and hazard ratio for in-hospital mortality was demonstrated by restricted cubic spline analysis (p = 0.0742). The Kaplan-Meier analysis illustrated that in-hospital mortality increased significantly in high SIRI group (p < 0.001). In addition, elevating SIRI was significantly associated with the incidence of coronary sinus tear (95%CI 1.020-4.475p = 0.044). Furthermore, the incidence rate of postoperative complications including renal failure (p < 0.001) and infection (p = 0.019) was higher in high SIRI group. CONCLUSION The study indicated that preoperative SIRI could provide strong prognostic value for in-hospital mortality in ATAD patients following open surgery. Thus, SIRI was a promising biomarker for risk stratification and management prior to open surgery.

Abstract
To explore the characteristics of big data of patients with allergic rhinitis, including the time, population and spatial distribution of allergic rhinitis in Beijing from 2016 to 2021, so as to provide reference for the prevention and treatment of this disease. Descriptive epidemiological methods were used to analyze the distribution (including gender, age and location)and trend of allergic rhinitis patients in 30 pilot hospitals from January 2016 to December 2021, T test and Kruskal-Wallis rank sum test were used to test the statistical differences. The results showed that the number of patients with allergic rhinitis in 30 hospitals increased year by year from 2016 to 2019, with an increase of 97.9%. In 2020, the number of patients decreased. In 2021, the number of visits returned to the pre-epidemic level (461 332); The number of patients with allergic rhinitis was the highest in September, with a seasonal index of 177.6%, while the lowest number was in February, accounting for only 47.2%; a significant difference was observed in the number of patients in different age groups(H=45 319.48, P<0.05), and patients under 15 years old accounted for the highest proportion(819 284 visits); There were significant differences between patients of different genders in the 45-59 year old group (t=-4.26, P<0.05).There were relatively more patients with allergic rhinitis in Dongcheng District(31.1%) than in Huairou District and Miyun District (0.4%). In conclusion, since 2016, the number of patients increased significantly, with a varied trend in different seasons. Most patients were children. There were more patients in the central urban area than in the outer suburbs.

Abstract
BACKGROUND Patients undergoing total knee arthroplasty (TKA) surgery are at high risk of chronic postsurgical pain (CPSP). Accumulating evidence suggests an active role of neuroinflammation in chronic pain. However, its role in the progression to CPSP following TKA surgery remains unanswered. Here, we examined the associations between preoperative neuroinflammatory states and pre- and postsurgical chronic pain in TKA surgery. METHODS The data of 42 patients undergoing elective TKA surgery for chronic knee arthralgia at our hospital were analyzed in this prospective study. Patients completed the following questionnaires: brief pain inventory (BPI), hospital anxiety and depression scale, painDETECT, and pain catastrophizing scale (PCS). Cerebrospinal fluid (CSF) samples were collected preoperatively and concentrations of IL-6, IL-8, TNF, fractalkine, and CSF-1 were measured by electrochemiluminescence multiplex immunoassay. CPSP severity was ascertained, using the BPI, 6 months postsurgery. RESULTS While no significant correlation was observed between the preoperative CSF mediator levels and preoperative pain profiles, the preoperative fractalkine level in the CSF showed a significant correlation with CPSP severity (Spearman's rho = -0.525; p = .002). Furthermore, multivariate linear regression analysis revealed that the preoperative PCS score (standardized β coefficient [β]: .11; 95% confidence interval [CI]: 0.06-0.16; p < .001) and CSF fractalkine level (β: -.62; 95% CI: -1.10 to -0.15; p = .012) were independent predictors of CPSP severity 6 months after TKA surgery. CONCLUSIONS We identified the CSF fractalkine level as a potential predictor for CPSP severity following TKA surgery. In addition, our study provided novel insights into the potential role of neuroinflammatory mediators in the pathogenesis of CPSP.

Abstract
BACKGROUND Despite the prolonged median disease-free survival (DFS) by adjuvant targeted therapy in non-small-cell lung cancer patients with epidermal growth factor receptor (EGFR) mutations, the relationship between the treatment duration and the survival benefits in patients remains unknown. PATIENTS AND METHODS In this multicenter, randomized, open-label, phase II trial, eligible patients aged 18-75 years with EGFR-mutant, stage II-IIIA lung adenocarcinoma and who had not received adjuvant chemotherapy after complete tumor resection were enrolled from eight centers in China. Patients were randomly assigned (1 : 1) to receive either 1-year or 2-year icotinib (125 mg thrice daily). The primary endpoint was DFS assessed by investigator. The secondary endpoints were overall survival (OS) and safety. This study was registered at ClinicalTrials.gov (NCT01929200). RESULTS Between September 2013 and October 2018, 109 patients were enrolled (1-year group, n = 55; 2-year group, n = 54). Median DFS was 48.9 months [95% confidence interval (CI) 33.1-70.1 months] in the 2-year group and 32.9 months (95% CI 26.6-44.8 months) in the 1-year group [hazard ratio (HR) 0.51; 95% CI 0.28-0.94; P = 0.0290]. Median OS for patients was 75.8 months [95% CI 64.4 months-not evaluable (NE)] in the 2-year group and NE (95% CI 66.3 months-NE) in the 1-year group (HR 0.34; 95% CI 0.13-0.95; P = 0.0317). Treatment-related adverse events (TRAEs) were observed in 41 of 55 (75%) patients in the 1-year group and in 36 of 54 (67%) patients in the 2-year group. Grade 3-4 TRAEs occurred in 4 of 55 (7%) patients in the 1-year group and in 3 of 54 (6%) patients in the 2-year group. No treatment-related deaths or interstitial lung disease was reported. CONCLUSIONS Two-year adjuvant icotinib was shown to significantly improve DFS and provide an OS benefit in EGFR-mutant, stage II-IIIA lung adenocarcinoma patients compared with 1-year treatment in this exploratory phase II study.

Abstract
OBJECTIVE To investigate the prevalence and influencing factors of soil-transmitted nematode infections in Ningbo City from 2016 to 2021, so as to provide insights into the development of targeted control measures against soil-transmitted nematodiasis. METHODS Permanent residents at ages of 3 years and older were sampled in Ningbo City using a multi-stage sampling method each year during the period from 2016 to 2021. Soil-transmitted nematode eggs were detected in stool samples using a modified Kato-Katz thick smear method (two slides for each stool sample), and Enterobius vermicularis eggs were additionally identified among children at ages of 3 to 12 years using the adhesive cellophane-tape perianal swab method. The time- and regions-specific prevalence of soil-transmitted nematode infections was calculated, and the factors affecting hookworm infections were identified using a multivariate logistic regression model. RESULTS A total of 11 573 person-times were detected for soil-transmitted nematode infections in Ningbo City from 2016 to 2021, and 296 egg-positives were detected, with a mean prevalence rate of 2.56% [95% confidential interval (CI): (2.28%, 2.87%)]. Hookworm was the predominant species of soil-transmitted nematode among egg-positives in Ningbo City (98.31%, 291/296), and there was a significant difference in the prevalence of hook-worm infections among years (χ2 = 190.27, P < 0.01). The highest prevalence of hook-worm infections was observed in Ninghai County (4.06%), and there was a region-specific prevalence rate of hookworm infection in Ningbo City (χ2 = 148.43, P < 0.01). Multivariate logistic regression analysis showed that elderly residents at ages of over 60 years [odds ratio (OR)= 1.94, 95% CI: (1.07, 3.54), P < 0.05], males [OR = 2.19, 95% CI: (1.72, 2.80), P < 0.01], farmers [OR = 6.94, 95% CI: (3.37, 14.29), P < 0.01] and residents with a low education level [illiteracy or semi-illiterate: OR = 3.82, 95% CI: (1.56, 9.35), P < 0.05; primary school: OR = 2.70, 95% CI: (1.11, 6.59), P < 0.05] were at a higher risk for hookworm infections. CONCLUSIONS The overall prevalence of soil-transmitted nematode infections was low among residents in Ningbo City from 2016 to 2021. The surveillance and health education for human hookworm disease remain to be reinforced among male farmers with a low education level at ages of over 60 years in Ninghai County.

Abstract
PURPOSE To investigate whether the metabolic score for insulin resistance (METS-IR) is associated with an increased risk of cardiovascular disease (CVD). METHODS A total of 6489 participants aged 35-70 years without a history of CVD were included in this prospective cohort study. The median follow-up time was 10.6 years. The METS-IR was calculated as ln [2 × FPG (mg/dL) + fasting TG (mg/dL)] × BMI (kg/m2)/ln [HDL-C (mg/dL)]. The primary outcome was CVD, defined as the composite of coronary heart disease (CHD) and stroke. RESULTS During follow-up, 396 individuals developed CVD. Kaplan-Meier survival curves by quintiles of METS-IR showed statistically significant differences (log-rank test, P < 0.001). Multivariate Cox regression analysis showed that the hazard ratio [95% confidence interval (95% CI)] of CVD was 1.80 (1.24-2.61) in quintile 5 and 1.17 (1.05-1.31) for per standard deviation (SD) increase in METS-IR. In subgroup analysis, the significant association between METS-IR and CVD was mainly observed among females and subjects without diabetes mellitus. A significant interaction was found between gender and METS-IR (P-interaction = 0.001). Moreover, adding METS-IR to models with traditional risk factors yielded a significant improvement in discrimination and reclassification of incident CVD. CONCLUSION The elevated METS-IR was independently associated with incident CVD, suggesting that the METS-IR might be a valuable indicator for risk stratification and early intervention of CVD.

Abstract
Purpose The involvement of hypoxic response mechanisms in local functional impairments in surgical wounds is unclear. In the present study, we characterized tissue hypoxia in surgical wounds and investigated the role of pharmacological ischemic conditioning (PIC) using roxadustat, an oral prolyl hydroxylase domain enzyme inhibitor, in postoperative local functional impairments in a murine model of deep hind paw incision. Methods Male BALB/cAJcl mice aged 9-13 weeks were used in all experiments. Plantar skins of mice that underwent surgical incision were subjected to immunohistochemistry to localise tissue hypoxia. Pain-like behaviours and sudomotor function were compared between mice treated with 6-week perioperative PIC and control mice. The effects of PIC were examined in vitro by immunocytochemistry using sympathetically differentiated PC12 cells and in vivo by immunohistochemistry using plantar skins collected on postoperative day 21. Results Prominent tissue hypoxia was detected within axons in the nerve bundles underneath surgical wounds. Six-week perioperative PIC using roxadustat failed to ease spontaneous pain-like behaviors; however, it mitigated local sudomotor impairment postoperatively. Upregulation of sympathetic innervation to the eccrine glands was observed in the PIC-treated skins collected on postoperative day 21, in accordance with the in vitro study wherein roxadustat promoted neurite growth of sympathetically differentiated PC12 cells. Conclusion This study suggests that tissue hypoxia is involved in the pathogenesis of local sudomotor dysfunction associated with surgical trauma. Targeting the hypoxic response mechanisms with PIC may be of therapeutic potential in postsurgical local sympathetic impairments that can be present in complex regional pain syndrome.

Abstract
BACKGROUND Defecation delay is a common symptom in patients after tricuspid valve replacement (TVR). Previous studies have demonstrated that defecation delay was associated with worse clinical outcomes of critically ill patients. Our study aimed to investigate the incidence and risk factors of defecation delay in patients after TVR and its adverse clinical outcomes. METHODS A retrospective study was conducted in 206 patients undergoing TVR under cardiopulmonary bypass from May 2005 to July 2021. According to the first postoperative defecation time after surgery, patients were divided into the delayed group (>3 days) and control group (≤3 days). Baseline characteristics and preoperative, intraoperative, and postoperative data were collected to investigate the clinical outcomes of defecation delay. RESULTS Among the 206 patients, 51.9% (107/206) cases were classified into the defecation delay group. Univariate analysis showed that age (P = 0.043), preoperative platelets (PLT) (P < 0.001), cardiopulmonary bypass (CPB) time (P = 0.013), minimum rectal temperature (P = 0.042), and the use of prokinetic drugs (P = 0.015) were significantly different in the two groups. In addition, the perioperative adverse events in the defecation delay group were significantly higher than that of the control group. Logistic regression analysis indicated that the mortality of patients was associated with postoperative renal dysfunction (P = 0.047) and postoperative respiratory failure (P = 0.004) but was not associated with defecation delay (P > 0.05). CONCLUSION Patients with defecation delay after TVR were more likely to appear adverse events, however, defecation delay was not associated with mortality after TVR.

Abstract
Low back pain (LBP) is an extremely common disorder and is a major cause of disability globally. Intervertebral disc degeneration (IVDD) is the main contributor to LBP. Nevertheless, the specific mechanisms underlying the pathogenesis of IVDD remain unclear. Mitochondria are highly dynamic organelles that continuously undergo fusion and fission, known as mitochondrial dynamics. Accumulating evidence has revealed that aberrantly activated mitochondrial fission leads to mitochondrial fragmentation and dysfunction, which are involved in the development and progression of IVDD. To date, research into mitochondrial dynamics in IVDD is at an early stage. The present narrative review aims to summarize the most recent findings about the role of mitochondrial fission in the pathogenesis of IVDD.

Abstract
BACKGROUND Patients with long-term tricuspid regurgitation (TR) are mostly accompanied by hepatic, cardiac, and venous remodeling. Transcatheter tricuspid valve replacement (TTVR) device has emerged as a promising alternative to open-heart surgery for TR patients. No study has assessed the impact of TTVR on hepatic, cardiac, and venous remodeling. METHODS Twenty-two patients with TR enrolled in this study underwent TTVR between October 2020 and January 2021. Liver, heart, and veins were reconstructed by three-dimensional computed tomography reconstruction software at baseline and 6 months follow-up. RESULTS Twenty-two patients were enrolled in this study. The mean age was 64.8 ± 8.2 years, and all patients had severe or greater TR with multiple comorbidities. The left hepatic lobe volume decreased from 518.8 ± 171.9 ml to 470.4 ± 179.6 ml at 6 months during follow-up (p = 0.049). Evidence of a decrease in three hepatic veins parameters and splenic vein parameters was noted from baseline to 6 months. And a significant decrease in right atrial volume (317.5 ml [interquartile range: 216.1 to 497.3 ml] vs. 266.7 ml [interquartile range: 178.7 to 480.7 ml]; p = 0.003) were observed in the study. CONCLUSIONS Six-month outcomes show that TR elimination by LuX-Valve is associated with the reverse remodeling of liver, heart, and veins. Accordingly, LuX-Valve is a promising alternative for patients presenting with severe TR.

Abstract
Background Lead-induced tricuspid regurgitation is one of the complications after permanent pacemaker implantation (PPI) and refers to tricuspid regurgitation (TR) caused by the lead in the right ventricle (RV). Objectives To study the clinical characteristics of severe TR after PPI and the effect of transcatheter tricuspid valve replacement (TTVR) with the guidance of 3-dimensional (3D) printing. Methods This study was a single-center, descriptive study. Six patients with severe TR after PPI were enrolled in Xijing Hospital from January 2020 to May 2020. Before TTVR, the 3D printed tricuspid valve (TV) model was used for evaluation in the bench test. LuX-Valve was implanted under the guidance of TEE and x-ray fluoroscopy, and all patients underwent transatrial access. Six patients' data were collected at baseline, before discharge, and 6 months, 1 year and 2 years after TTVR. Results The LuX-Valve was successfully implanted in 6 patients, TR was significantly reduced to ≤2+, and no deaths or cardiopulmonary bypass occurred during procedures. Three cases were caused by TV expansion: Patient #4 had TR caused by lead adhesion to TV, Patient #2 had TR caused by lead winding, and Patient #6 had TR caused by lead impingement on TV. During the 2-year follow-up, TTE revealed that 5 patients had no/trace regurgitation, and one patient (Patient #5) had mild regurgitation. All 6 patients (100.0%) reached primary endpoints. Conclusion TTVR guided by 3D printing is safe and effective in the treatment of severe TR associated with permanent pacemaker lead, providing prospects and possibilities for the precise treatment of TV-related diseases.Clinical Trial Registration: ClinicalTrials.gov Protocol Registration System (NCT02917980).

Abstract
The purpose of this study is to determine whether preoperative 6-minute walk test (6MWT) is associated with prolonged postoperative hospitalization in high risk patients with severe tricuspid regurgitation (TR) after transcatheter tricuspid valve replacement (TTVR). Forty-one patients with severe TR who underwent TTVR and discharged between September 2018 and April 2021 were enrolled in this study. Patients were divided into 2 groups according to whether the postoperative hospital stay was >10 days and patients' data were retrospectively collected. 6MWT was performed before operation. Twenty-one patients were in the control group (≤10 days) and 20 patients were in the prolonged postoperative stay (PPS) group (>10 days). 6MWT distance was significantly decreased in PPS group (192.70 ± 62.34 vs 274.57 ± 52.09 m, P < .05). PPS group had more patients with severe liver disease (50.00% vs 19.05%, P < .05), higher systolic pulmonary artery pressure (45.05 ± 9.28 vs 35.57 ± 8.91 mm Hg, P < .05) and longer procedure time (159.85 ± 56.61 vs 124.43 ± 31.67 min, P < .05). Multivariable logistic regression analysis found 6MWT <267 m was an independent risk factor with the odds ratio of 10.95 (1.66-72.39, P < .05) for prolonged postoperative hospitalization in patients who received TTVR. In the present study, we identified that preoperative decreased 6MWT distance was an independent risk factor for prolonged hospitalization in high risk TR patients after TTVR.

Abstract
Chronic refractory wounds and scars caused by abnormal wound repair seriously damage the health of patients and affect their quality of life. At present, there is a lack of simple but effective and economical treatment methods. Adipose-derived stem cells (ASCs), as a kind of mesenchymal stem cells with multi-directional differentiation potential, have been confirmed by several in vivo and in vitro studies to promote wound healing by promoting epithelialization, angiogenesis, immunoregulation, antioxidant properties, and other mechanisms. ASCs and their derivatives have been used in the treatment of refractory wounds caused by burns, diabetic, and radiation injuries with good results achieved. Their potential to become new materials for wound repair has also been confirmed. This paper reviewed the mechanism and clinical application of ASCs in promoting wound repair, and looked into its research direction and prospects.

Abstract
Transcatheter aortic valve implantation (TAVI) has become a popular treatment for surgical high-risk patients with severe aortic stenosis (AS). Recently, we have applied TAVI to the treatment of aortic regurgitation (AR). Compared with conventional surgical procedures, TAVI is less invasive and considered a useful option for these high-risk patients. In this study, we reported a patient who underwent transapical TAVI. The patient was a 52-year-old female with Takayasu arteritis (TA) for 25 years, as well as with severe aortic regurgitation, porcelain aortas, and heart failure. Transapical TAVI successfully was accomplished without neurological complications, and heart failure immediately improved postoperatively.

Abstract
This study explored the correlation between peripheral blood CD3+, CD3+/CD4+, CD3+/CD8+, CD4+/CD8+, CD3-/CD16+ CD56+, and CD3-CD19+ and disease activity of different subtypes of systemic lupus erythematosus (SLE). The percentages of CD3+, CD3+/CD4+, CD3+/CD8+, CD4+/CD8+, CD3-/CD16+ CD56+, and CD3-CD19+ in the peripheral blood of patients (n = 80) classified into lupus nephritis, blood involvement, and joint involvement and SLE in different active stages were detected by flow cytometry. Their correlations with baseline clinical experimental indicators of SLE patients' SLE disease activity index score (SLEDAI) and complement C3 were analyzed. The results showed that CD3+, CD3+/CD4+, and CD3+/CD8+ at baseline level were negatively correlated with SLEDAI scores. These were positively correlated with C3. In conclusion, T-lymphocyte subpopulations are closely related to SLE activity and can be used as reference indicators to evaluate the SLE activity.

Abstract
OBJECTIVE To explore the clinical value of high mobility group box-1 (HMGB-1), C-reactive protein (CRP), procalcitonin (PCT), and CRP to albumin (Alb) ratio in the diagnosis and evaluation of the severity of sepsis in children. PATIENTS AND METHODS A total of 90 children, 50 with sepsis and 40 with general infection, whose symptoms did not meet the criteria for diagnosis of sepsis, were admitted to the Pediatrics Department of Jingzhou Central Hospital in Hubei Province between November 2021 and December 2022, were enrolled and selected as experimental and control group, respectively. The serum of two groups was collected within 24 hours after admission, the levels of HMGB-1 were detected by enzyme-linked immunosorbent assay (ELISA), and CRP, PCT, Alb, and hospitalization days were recorded. The differences in indicators between the two groups were compared, and correlation analysis was performed between hospitalization days and various indicators. The receiver operating characteristic (ROC) curve was drawn to evaluate the independent or combined value of CRP, PCT, HMGB-1, and CRP/Alb ratio in the early diagnosis of sepsis in children. RESULTS These four indicators of children with sepsis were significantly higher than those in the general infection group (all p=0.000). The levels of CRP, PCT and CRP/Alb ratio were significantly positively correlated with the hospitalization days (r=0.329, 0.333, 0.329; p=0.02, 0.01, 0.002). The area under curve (AUC) of CRP, PCT, HMGB-1, and CRP/Alb ratio for the diagnosis of sepsis in children was 0.798, 0.817, 0.838, 0.809, respectively, and that of the combination of four indicators was 0.952. CONCLUSIONS CRP, PCT, HMGB-1, and CRP/Alb ratio resulted as effective indicators for early diagnosis and evaluation of childhood sepsis, having a higher value in combined diagnosis.

Abstract
Background The paucity of objective and reliable measurements of pain-like behaviors has impeded the translatability of mouse models of postsurgical pain. The advanced dynamic weight-bearing (DWB) system enables evaluation of spontaneous pain-like behaviors in pain models. This study investigated the suitability and efficiency of the DWB system for assessing spontaneous pain-like behaviors and analgesic therapies in murine models of postsurgical pain. Methods Male adult C57BL/6JJcl mice were subjected to multiple surgical pain models with distinct levels of invasiveness, including a superficial incisional pain model involving only hind paw skin incision, deep incisional pain model that also involved incision and elevation of the underlying hind paw muscles, and orthopedic pain model involving tibial bone fracture and fixation with a pin (fracture and pinning [F/P] model). Spontaneous pain-like behaviors post-surgery were evaluated using weight distribution, pawprint area of the operated paw in the DWB system, and guarding pain score. Mechanical hypersensitivity was assessed using the von Frey test. The therapeutic effects of analgesics (diclofenac and buprenorphine for the deep incision model and diclofenac for the F/P model) were evaluated using the DWB system and von Frey test. Results The von Frey test demonstrated contradictory results between superficial and deep incisional pain models. The DWB system captured weight distribution changes in the operated hind paw, in accordance with the invasiveness and time course of wound healing in these surgical pain models. The reduction in weight-bearing on the operated paw correlated with guarding score, degree of paw swelling, and local expression of inflammatory mediators. DWB enabled accurate evaluation of the pharmacological effects of analgesics for detecting attenuation of surgery-induced weight-bearing changes in these models. Conclusion The DWB system serves as an objective and reliable method for quantifying pain-like behaviors and evaluating the therapeutic effects of analgesics in mouse models of postsurgical pain models.

Abstract
Objective: To investigate the different tracer materials in identifying the axillary reverse mapping(ARM) lymph nodes. Methods: A retrospective analysis of clinical and pathological data of 478 breast cancer female patients(mean age: 50.5±8.0) under axillary lymph node dissection(ALND) with ARM technique was conducted between March 2019 and November 2020 in Wuhan University Zhongnan Hospital. Of the 478 patients, methylene blue was applied in 147 patients, indocyanine green in 119, and indocyanine green plus methylene blue in 212 patients. Wilcoxon rank-sum test, Chi-squire test or Fisher test, and binary logistic regression were carried out to identify the factors associated with identifying ARM lymph nodes. Results: The recognition rates of ARM lymph nodes were 73.5%, 79.0%, and 83.0%(P=0.091), and the recognition rate of ARM lymphatic vessels was 62.6%, 92.4%, 89.6%(P<0.001), respectively. The coincidence rate of ARM lymph node and SLN was 8.1%(12/148), and the metastasis rate was 16.1%(61/378). Supplemental injection of 1 ml of methylene blue or indocyanine green can improve the identification of ARM lymph nodes. The larger BMI and the performance of neoadjuvant therapy were associated with the lower recognition rate of ARM lymph nodes. Neoadjuvant therapy was an independent factor for the identification rate of ARM lymph nodes. Conclusions: Indocyanine green combined with methylene blue can improve the recognition rate of ARM lymph nodes. Obese patients have a lower recognition rate of ARM lymph nodes, and the supplemental injection tracer can be injected to improve the recognition rate. In breast cancer patients whose ARM lymph nodes are not successfully identified during operation, it may be that the ARM lymph nodes are not located in the axilla.

Abstract
AIM Immature necrotic teeth are frequent findings in adolescents that may lead to thin root walls and open apexes. The absence of an apical stop becomes a challenge for endodontic treatment because it is difficult or impossible to seal the immature root canal with conventional endodontic techniques. Revascularisation therapy (RET) may be more suitable for the treatment of immature necrotic teeth. However, clinicians are still more inclined to choose apexification (AP) when considering the predictability of treatment results. METHODS The literature was searched via PubMed/MEDLINE and the Cochrane Library, Web of Science data from June, 2001 to September, 2020 and randomised clinical trials were selected that compared RET with AP for the treatment of immature necrotic teeth assessing clinical and radiographic results. RESULTS A total of 556 articles were retrieved, though only five studies were included. There were no differences in the periapical healing rate, overall effective rate/invalid rate, or apical closure rate between RET and AP. The root length was significantly increased in the RET group compared with the AP group quantitatively (pooled difference in means=1.28, 95% CI: [1.08, 1.48], Z=12.69, P<0.00001) and qualitatively (pooled RR=4.12, 95% CI: [2.44, 6.97]), Z=5.28, P<0.00001). The effective rate of root thickness was significantly increased in the RET group compared with the AP group (pooled RR=22.63, 95% CI: [6.08, 84.26]), Z=4.65, P<0.00001). CONCLUSIONS Both RET and AP were effective options regarding the healing of periapical periodontitis or the closure of open apices. Pulp revascularisation is more effective for root elongation and thickening without higher risk of overall invalid treatment.

Abstract
OBJECTIVE The current study aimed to illustrate whether wogonin influences HCC cell cycle progression and apoptosis by regulating Hippo signaling. <P> Methods: The effects of wogonin on HCC cell viability, cell cycle progression and apoptosis were analyzed by utilizing CCK-8 and flow cytometry. RNA-seq was employed to analyze the expression profiles between wogonin-treated and control HCC cells, and the selected RNA-seq transcripts were validated by reverse transcription-quantitative real-time polymerase chain reaction (RT-qPCR). Immunofluorescence staining was performed to detect the distribution of YAP/TAZ in the nucleus and cytoplasm in HCC cells. Western blotting and human apoptosis array were performed to examine the expression of the indicated genes. <P> Results: We demonstrated that wogonin induced cell cycle arrest and apoptosis of HCC cell lines SMMC7721 and HCCLM3. RNA-seq analysis showed enrichment in genes associated with cell cycle progression and apoptosis following incubation with wogonin in HCC cells, and the pathways analysis further identified that Hippo signaling pathways highly altered in wogonin-treated cells. Specifically, wogonin increased the phosphorylation of MOB1 and LATS1, promoted translocation of endogenous YAP and TAZ from the nucleus to the cytoplasm, and facilitated phosphorylation of YAP and TAZ. Notably, overexpression of YAP or TAZ partially abrogated the wogonin-mediated HCC cell cycle arrest and apoptosis, and reversed wogonin-mediated suppression of Claspin. <P> Conclusion: Wogonin induced HCC cell cycle arrest and apoptosis probably by activating MOB1-LATS1 signaling to inhibit the activation of YAP and TAZ, and then decrease the expression of Claspin, suggesting that the understanding of the molecular mechanisms underlying wogonin-induced cell cycle arrest and apoptosis may be useful in HCC therapeutics.

Abstract
Abstract
Study question
Is ERA testing different between RIF patients with control group?
Summary answer
In RIF patients, there were more chances of non-receptive endometrium. ERA testing may be helpful for the patients with repeated IVF failure. What is known already: The endometrium receptivity analysis testing might have the ability to detect the implantation window. In repeat implantation failure patients, detecting of precisely implantation window may have some benefits.
Study design, size, duration
This was a single-center retrospective observational study. Two hundred and forty-nine patients who underwent ERA testing following frozen-thawed embryo transfer in our center were including in this study between January 2019 and May 2020.
Participants/materials, setting, methods
181 patients having unexplained repeated IVF failure (RIF group, at least tow implantation failure) and 68 patients having no experience with embryo transfer (Control group) who underwent ERA testing were including in this study. Both of Patients having a receptive (R) ERA and having a non-receptive (NR) ERA underwent a personalized embryo transfer (pET) on ERA. ERA results and clinical outcomes compared between RIF group and control group were analyzed by Chi-square test.
Main results and the role of chance
The proportion of R/NR results were 33:35 for the RIF group and 118:63 for the Control group, demonstrating the displacement of the window of implantation in patients with RIF. Our results revealed an endometrial factor in 51% RIF patients, which was significantly greater than the Control group 34.8% (P = 0.02). Among the patients with NR ERA result, there are not significantly difference in clinical pregnancy rate in the RIF group compared with control group (57.1%. vs. 61.9%). The clinical pregnancy rate of the patients with receptive ERA result also is comparable in both group (70.3% vs. 66.7%).
Limitations, reasons for caution
This is a retrospective, single center study with limited case number. There were may some bias with ERA testing errors.
Wider implications of the findings: In RIF patients, there were more chances of non-receptive endometrium. ERA testing may be helpful for the patients with repeated IVF failure. Larger randomized studies are required to validate these results.

Abstract
To determine whether curcumin (Cur) can treat mice with experimentally-induced colitis by regulating follicular helper T cells (Tfh) and follicular regulatory T cells (Tfr) by inhibiting interleukin (IL)-21. In this study, 40 male C57BL/6 mice were randomly grouped into four groups, i.e., normal, trinitrobenzene sulfonic acid (TNBS), TNBS + curcumin, and TNBS + anti-IL-21. Mice with experimental colitis were induced by 100 mg/kg TNBS. The mice in the TNBS + Cur group were treated with 100 mg/kg curcumin for seven days, and mice in the TNBS + anti-IL-21 group were treated with anti-IL-21 (150 μg/mouse) once per week, intraperitoneally, starting on the second day after establishing the experimental colitis model. On day eight, the therapeutic effect of curcumin was evaluated by colon mucosa damage index (CMDI), histological examination, and disease activity index (DAI). Furthermore, the number of CD4 + CXCR5 + PD-1 + Tfh and CD4 + CXCR5 + FoxP3 + Tfr cells were measured by flow cytometry. The mRNA and protein expression of IL-21, Bcl-6, FOXP3, ICOS, and PD-1 in colonic mucosa was detected by reverse transcription polymerase chain reaction and the Western blot technique. Compared with the TNBS group, the DAI, CMDI, histological score, the number of CD4 + CXCR5 + PD-1 + Tfh cells, the expression of IL-21, Bcl-6, ICOS, and PD-1 were significantly decreased in the TNBS + curcumin group and TNBS + anti-IL-21 group; body weight, number of CD4 + CXCR5 + FoxP3 + Tfr cells, and the expression of FoxP3 were observably elevated in the TNBS + curcumin group (all P < 0.05). Curcumin may have a potential therapeutic effect on mice with colitis treated experimentally through regulation of the balance of Tfh and Tfr cells via inhibiting the synthesis of IL-21.

Abstract
Background:Rituximab is an effective therapy for rheumatoid arthritis (RA) patients with inadequate responses to methotrexate (MTX)1, 2. However, it has not been registered or approved in China for the treatment of RA by far. HLX01, an approved rituximab biosimilar (demonstrated in Chinese patients with diffuse large B-cell lymphoma)3, is thus evaluated in this study for the benefits of Chinese RA patients.Objectives:This study aimed to evaluate the efficacy and safety of HLX01 plus MTX versus placebo plus MTX in Chinese patients with active RA who had inadequate responses to MTX.Methods:This was a randomised, double-blind, placebo-controlled phase 3 study conducted in China (NCT03522415). Eligible patients were randomised 2:1 to receive intravenous infusion of 2×1000 mg HLX01 or placebo on day 1 and day 15. Patients with inadequate responses at week 16 and 20 were allowed to receive rescue treatments. Patients were retreated with or switched to receive (if initially assigned to placebo) 2×1000 mg rituximab at the first day of week 24 and 26. The primary endpoint of this study was the American College of Rheumatology criteria (ACR) 20 response at week 24. Secondary efficacy endpoints were evaluated at week 12, 24, 36 and 48. The safety, pharmacokinetics, pharmacodynamics and immunogenicity of HLX01 were observed and analyzed throughout the study.Results:Between May 28, 2018 and Sep 11, 2020, a total of 275 patients (ITT set) were randomised and 263 patients without major protocol deviations were included in per-protocol set (PPS). At week 24, HLX01 showed statistically superior efficacy (p <0.001) to placebo (ACR20: 60.7% vs 35.9% in ITT set, 60.3% vs 37.1% in PPS). Secondary efficacy endpoints were also significantly improved in HLX01 group compared with placebo (Table 1). The overall incidence of serious treatment emergent adverse events (TEAEs), adverse drug reactions (ADRs), and TEAEs leading to drug discontinuation were similar among treatment groups, with the most common TEAE been upper respiratory tract infection before (18.1% vs 18.5%) or after (13.0% vs 12.3%) week 24. Serum concentrations, immunogenicity and pharmacodynamics were similar between HLX01 and placebo groups.Table 1.Results of secondary efficacy endpoints at week 12, 24, 36 and 48 in ITT set.DurationSecondary efficacy endpointsACR20 (%)ACR50 (%)ACR70 (%)DAS28-CRP(mean)HAQ-DI(mean)HLX01PlaceboHLX01PlaceboHLX01PlaceboHLX01PlaceboHLX01PlaceboBaseline5.495.431.401.45Week 1248.132.621.910.94.45.43.894.471.021.22Week 2460.735.936.618.515.312.03.394.370.871.22Week 3660.148.946.431.532.217.42.883.510.710.97Week 4873.862.055.240.239.927.22.823.510.721.03Conclusion:Comparing with placebo plus MTX, HLX01 plus MTX showed significantly improved clinical outcomes and comparable safety profiles in Chinese patients with moderately to severely active RA who had inadequate responses to MTX, demonstrating HLX01 in combination with MTX as a well-tolerated, safe and efficient treatment option.References:[1]Emery P, Deodhar A, Rigby WF, et al.

Abstract
Objective: To investigate the effect of plasma uric acid level on the incident risk of type 2 diabetes mellitus (T2DM) among the oldest old (those aged ≥80 years). Methods: Participants were recruited from the Healthy Aging and Biomarkers Cohort Study (HABCS), which conducted a baseline survey in 2008-2009 and follow-up of 3 times in 2011-2012, 2014, and 2017-2018, respectively. A total of 2 213 oldest old were enrolled in this study. The general demographic, socioeconomic, lifestyle and disease data of the oldest old were collected, and physical measurements were made for the oldest old. Fasting venous blood was collected for uric acid and blood glucose detection. Information on the incident and death of T2DM were collected through the follow-up. Cox proportional hazard regression model was used to explore the association of hyperuricemia and plasma uric acid level with the incidence of T2DM. Restricted cubic spline (RCS) function was used to explore the dose-response relationship of plasma uric acid levels with the risk of T2DM. Results: The age of participants was (93.2±7.6) years old, and 66.7% of the participants (1 475) were female. The plasma uric acid level at baseline was (289.1±88.0)μmol/L, and the prevalence of hyperuricemia was 13.3% (294 cases). During 9 years of cumulative follow-up of 7 471 person-years (average of 3.38 years for each), 122 new cases of T2DM occurred and the incidence density was 1 632.98/105 person year. Cox proportional hazards regression analysis showed that per 10μmol/L increase in plasma uric acid level, the risk of T2DM increased by 1.1% [HR (95%CI): 1.011 (1.004, 1.017)]. Compared with the participants with the lowest quintile of plasma uric acid (Q1), the risk of diabetes increased by 20.7 % among the oldest old with uric acid in the highest quintile (Q5) [HR (95%CI):1.207 (1.029, 1.416)]. The risk of T2DM was 19.2% higher in the hyperuricemia group than that in the oldest old with normal plasma uric acid [HR (95%CI): 1.192 (1.033, 1.377)]. RCS function showed that the risk of T2DM increased with the increase in plasma uric acid levels in a nonlinear dose-response relationship (P=0.016). Conclusion: The incident risk of T2DM increases with the elevates of plasma uric acid levels in the oldest old.

Abstract
Antifungal innate immunity is an important defence used by insects against entomogenous fungi. However, the downstream target antifungal peptides of different immune signalling pathways are unknown. We found that the Toll, Janus kinase/signal transducer and activator of transcription (Jak/STAT) and Immunodeficiency (IMD) signalling pathways in the silkworm, Bombyx mori, can be activated by Beauveria bassiana. Inhibition of the Toll, IMD and Jak/STAT signalling pathways reduced the antifungal activities of silkworm haemolymph. We verified the target antifungal peptides of different immune signalling pathways. The expression patterns of five anti-fungal peptide genes in silkworm larvae and BmN cells were detected after blocking or over-expressing the immune signalling pathways. The Toll signalling pathways mediated the expression of Bmcecropin A, Bmattacin 1 and Bmgloverin 2; IMD signalling pathways mediated Bmenbocin 1, Bmgloverin 2 and Bmattacin 1; Jak/STAT signalling pathways mediated Bmstorage protein 30K-19G1 (Bmsp 1), Bmattacin 1 and Bmcecropin A. These data indicated that anti-microbial peptide genes in B. mori evolved through expansion and selection of existing genes to adapt to the challenge of invasive microorganisms such as fungi. This information provides insight into the antifungal immune responses in B. mori and aids understanding of insect immune regulation mechanisms.

Abstract
Designing public health responses to outbreaks requires close monitoring of population-level health indicators in real-time. Thus, an accurate estimation of the epidemic curve is critical. We propose an approach to reconstruct epidemic curves in near real time. We apply this approach to characterize the early SARS-CoV-2 outbreak in two Spanish regions between March and April 2020. We address two data collection problems that affected the reliability of the available real-time epidemiological data, namely, the frequent missing information documenting when a patient first experienced symptoms, and the frequent retrospective revision of historical information (including right censoring). This is done by using a novel back-calculating procedure based on imputing patients' dates of symptom onset from reported cases, according to a dynamically-estimated "backward" reporting delay conditional distribution, and adjusting for right censoring using an existing package, NobBS , to estimate in real time (nowcast) cases by date of symptom onset. This process allows us to obtain an approximation of the time-varying reproduction number ( R t ) in real-time. At each step, we evaluate how different assumptions affect the recovered epidemiological events and compare the proposed approach to the alternative procedure of merely using curves of case counts, by report day, to characterize the time-evolution of the outbreak. Finally, we assess how these real-time estimates compare with subsequently documented epidemiological information that is considered more reliable and complete that became available later in time. Our approach may help improve accuracy, quantify uncertainty, and evaluate frequently unstated assumptions when recovering the epidemic curves from limited data obtained from public health surveillance systems in other locations.

Abstract
Objective: To investigate the association between blood lead concentrations and cognition impairment among Chinese older adults aged 65 or over. Method: Data was collected in 9 longevity areas from Heathy Aging and Biomarkers Cohort Study between 2017 and 2018. This study included 1 684 elderly aged 65 years and older. Information about demographic characteristics, socioeconomic factors, health status and cognitive function score of respondents were collected by questionnaire survey and physical examination. Venous blood of the subjects was collected to detect the blood lead concentration. Subjects were stratified into four groups (Q1-Q4) by quartile of blood lead concentration. Multivariate logistic regression model was used to analyze the association between blood lead concentration and cognitive impairment. The linear or non-linear association between blood lead concentration and cognitive impairment were described by restrictive cubic splines (RCS). Results: Among the 1 684 respondents, 843 (50.1%) were female and 191 (11.3%) suffered from cognition impairment. After adjusting for confounding factors, the OR value and 95%CI of cognition impairment was 1.05 (1.01-1.10) for every 10 μg/L increase in blood lead concentration in elderly; Compared with the elderly in Q1, the elderly with higher blood lead concentration had an increased risk of cognitive impairment. The OR value and 95%CI of Q2, Q3 and Q4 groups were 1.19 (0.69-2.05), 1.45 (0.84-2.51) and 1.92 (1.13-3.27), respectively. Conclusion: Higher blood lead concentration is associated with cognitive impairment among the elderly aged 65 years and older in 9 longevity areas in China.

Abstract
Objective: To investigate the association of blood oxidative stress level with hypertriglyceridemia in the elderly aged 65 years and older in China. Methods: A total of 2 393 participants aged 65 years and older were recruited in 9 longevity areas from Heathy Aging and Biomarkers Cohort Study, during 2017 to 2018. Information on demographics characteristic, life style and health status were collected by questionnaire and physical examination, and venous blood was collected to detect the levels of blood oxidative stress and hypertriglyceridemia. The linear or non-linear association between oxidative stress and hypertriglyceridemia was described by restrictive cubic splines (RCS) fitting multiple linear regression model. The generalized linear mixed effect model was conducted to assess the association between oxidative stress and hypertriglyceridemia. Results: A total of 2 393 participants, mean age was 84.6 years, the youngest was 65 and the oldest was 112, the male was 47.9%(1 145/2 393), the triglyceride level was (1.4±0.8) mmol/L. The hypertriglyceridemia detection rate was 9.99%(239/2 393). The results of multiple linear regression model with restrictive cubic spline fitting showed that MDA level was linear association with triglyceride level; SOD level was nonlinear association with triglyceride level. MDA level had significantly association with hypertriglyceridemia, and the corresponding OR value was 1.063 (95%CI: 1.046,1.081) with 1 nmol/ml increment of blood MDA; SOD level had significantly association with hypertriglyceridemia, and the corresponding OR value was 0.986(95%CI: 0.983,0.989) with 1 U/ml increment of blood SOD. Conclusion: Among the elderly aged 65 and older in 9 longevity areas in China, MDA and SOD levels were associated with the risk of hypertriglyceridemia.

Abstract
OBJECTIVE The aim of this study is to investigate the relation between CaMKII S-nitrosylation and its activation, as well as the underlying mechanism, after global cerebral ischemia-reperfusion. MATERIALS AND METHODS The rat model of cerebral ischemia-reperfusion was established by four-vessel occlusion of 15 min and reperfusion of different times. nNOS inhibitor 7-nitroindazole (7-NI), exogenous nitric oxide donor GSNO (nitrosoglutathione), or N-methyl-D-aspartate receptor (NMDAR) antagonist MK-801 were administered before ischemia. The expressions of S-nitrosylation and phosphorylation of CaMKII and nNOS were detected by biotin switch assay, immunoblotting, and immunohistochemical staining after cerebral ischemia-reperfusion. The survival of hippocampal CA1 pyramidal cells after administration of the three drugs was examined by cresyl violet staining. RESULTS Following cerebral ischemia-reperfusion, the S-nitrosylation of CaMKII was increased, accompanied by a decrease of phosphorylation, suggesting a decrease of activity (p<0.05). Meanwhile, the phosphorylation and S-nitrosylation of nNOS were notably decreased at the same time point (p<0.05). The administration of 7-NI, GSNO, and MK-801 increased the S-nitrosylation and phosphorylation of nNOS, leading to the attenuation of increased S-nitrosylation and decreased autophosphorylation of CaMKII after cerebral ischemia-reperfusion (p<0.05). Administration of MK-801, GSNO, and 7-NI significantly decreased the neuronal damage in rat hippocampal CA1 caused by cerebral ischemia-reperfusion (p<0.05). CONCLUSIONS After cerebral ischemia-reperfusion, the decrease of autophosphorylation of CaMKII regulated by its S-nitrosylation may be due to the denitrosylation of nNOS and subsequent NO production. Increasing the phosphorylation of CaMKII by nNOS inhibitor, exogenous NO donor or NMDA receptor antagonist exerted neuroprotective effects against cerebral ischemia-reperfusion injury.

Abstract
Background:Cardiac involvement is a serious complication of idiopathic inflammatory myopathy (IIM). Early diagnosis and intervention can improve prognosis. At present, myocardial biopsy is the gold standard for its diagnosis, but it is not commonly used because of its invasiveness. Biomarkers can be invoked as a non-invasive and convenient choice. The traditional markers of myocardial injury, as troponin and creatine kinase are lack specificity in inflammatory myopathy, so the novel biomarkers are getting attention.GDF-15 can predict the risk of cardiovascular disease and the prognosis of coronary atherosclerosis, heart failure and other diseases.Objectives:This article was intended to investigate the diagnostic value of GDF-15 for myocardial involvement in inflammatory myopathy.Methods:This retrospective study included 54 patients with inflammatory myopathy from May 2018 to October 2019.Of these,30 patients underwent cardiac magnetic resonance examination due to increased myocardial markers, excluding 1 case of severe lung infection. 33 patients with systemic lupus erythematosus (SLE),16 normal patients were used as the control group.The concentration of GDF-15 in the serum of all groups of patients was measured by ELISA.Results:1. There were significantly differences in GDF-15 levels in patients with inflammatory myopathy, systemic lupus erythematosus and normal subjects (H =39.870, P <0.001).2. 29 patients with cardiac magnetic resonance on the basis of the delayed enhancement (LGE) and ECV results were divided into two groups in which 19 patients with myocardial injury group and 10 patients without myocardial injury. The best cut-off value was calculated by ROC curve,and comparing GDF-15 and CKMB with the optimum cut-off values in predicting cardiac involvement in IIM.GDF-15 levels were statistically significant between the myocardial injury group (1765.868±1068.549 pg/ml) and the group without myocardial injury(689.967±458.12 pg/ml)(p =0.0011).At the same time, the creatine kinase isoenzyme (CKMB)(158.583±119.389 U/L vs 57.96±52.673 U/L, p =0.005) was statistically different between the two groups.3.GDF-15≥1005.3650pg/ml (AUC =0.853,95% CI 0.694-1.000) predicted myocardial involvement in inflammatory diseases with a sensitivity of 0.765 and specificity of 0.900.The AUC of the ROC curve for the joint detection of GDF-15 and CKMB was 0.888,95% CI0.757-1.000,with the predicted probability cut-off value in 0.3895, the sensitivity 0.941 and the specificity 0.800.The combined detection of the two increased the sensitivity of myocardial damage detection in IIM patients. 5. After adjusted for age, renal function, the risk of myocardial injury in IIM patients increased by an average of 0.3% per unit of GDF-15(OR =1.003,95% CI 1.000–1.005).Conclusion:GDF-15 can predict myocardial injury in patients with inflammatory myopathy which have high specificity.The prediction sensitivity can be improved by combining with the traditional myocardial enzyme CKMB.More further studies are needed to confirm the specific mechanism of GDF-15 for myocardial involvement to assess the prognosis of such patients and guide further treatment.References:[1]Sultan SM, Ioannou Y, Moss K, Isenberg DA.
