Abstract
Pancreatic cancer (PC) is a highly malignant cancer characterized by poor prognosis, high heterogeneity, and intricate heterocellular systems. Selecting an appropriate experimental model for studying its progression and treatment is crucial. Patient-derived models provide a more accurate representation of tumor heterogeneity and complexity compared to cell line-derived models. This review initially presents relevant patient-derived models, including patient-derived xenografts (PDXs), patient-derived organoids (PDOs), and patient-derived explants (PDEs), which are essential for studying cell communication and pancreatic cancer progression. We have emphasized the utilization of these models in comprehending intricate intercellular communication, drug responsiveness, mechanisms underlying tumor growth, expediting drug discovery, and enabling personalized medical approaches. Additionally, we have comprehensively summarized single-cell analyses of these models to enhance comprehension of intercellular communication among tumor cells, drug response mechanisms, and individual patient sensitivities.

Abstract
OBJECTIVE To enhance the accuracy in predicting lymph node metastasis (LNM) preoperatively in patients with papillary thyroid microcarcinoma (PTMC), refining the "low-risk" classification for tailored treatment strategies. METHODS This study involves the development and validation of a predictive model using a cohort of 1004 patients with PTMC undergoing thyroidectomy along with central neck dissection. The data was divided into a training cohort (n = 702) and a validation cohort (n = 302). Multivariate logistic regression identified independent LNM predictors in PTMC, leading to the construction of a predictive nomogram model. The model's performance was assessed through ROC analysis, calibration curve analysis, and decision curve analysis. RESULTS Identified LNM predictors in PTMC included age, tumor maximum diameter, nodule-capsule distance, capsular contact length, bilateral suspicious lesions, absence of the lymphatic hilum, microcalcification, and sex. Especially, tumors larger than 7 mm, nodules closer to the capsule (less than 3 mm), and longer capsular contact lengths (more than 1 mm) showed higher LNM rates. The model exhibited AUCs of 0.733 and 0.771 in the training and validation cohorts respectively, alongside superior calibration and clinical utility. CONCLUSION This study proposes and substantiates a preoperative predictive model for LNM in patients with PTMC, honing the precision of "low-risk" categorization. This model furnishes clinicians with an invaluable tool for individualized treatment approach, ensuring better management of patients who might be proposed observation or ablative options in the absence of such predictive information.

Abstract
Objective: To assess and compare the diagnostic efficacy of next-generation ultrathin bronchoscopy (UTB) and conventional bronchoscopy (CB), both combined with radial endobronchial ultrasound (r-EBUS), in the evaluation of peripheral pulmonary lesions (PPL). Methods: A cohort of 39 patients with PPL who underwent multimodal bronchoscopy at Dushu Lake Hospital, Soochow University, from June 1, 2021 to May 31, 2023 was consecutively enrolled. A single bronchoscopist performed multimodal bronchoscopies using CB (external diameter 4.9 mm or 5.9 mm, working channel diameter 2 or 3 mm, CB group) for transbronchial biopsy under r-EBUS guidance (rEBUS-TBLB), followed by UTB (external diameter 3 mm, working channel diameter 1.7 mm, UTB group) for transbronchial biopsy under r-EBUS guidance. Pathological findings and a 6-month clinical follow-up were used as the gold standard to compare the diagnostic yield of biopsy specimens, ultrasound characteristics, and localization rates of the two bronchoscope types. The aim was to evaluate the clinical application value of UTB combined with r-EBUS. Binary variables were analysed using the McNemar test for paired data. Continuous variables or ranked data were analysed using the Wilcoxon signed-rank test for paired data. Results: The diagnostic yields for UTB and CB groups were 66.67% (26/39) and 30.77% (12/39), respectively, with the UTB group significantly surpassing the CB group (χ2=10.56, P=0.001, 1-β=0.968). r-EBUS with CB exhibited no visible lesion in 13 cases, adjacent to the lesion in 19 cases, and within the lesion in 7 cases.Substitution of UTB resulted in r-EBUS images changing from no visible lesion to adjacent to the lesion in 7 cases, from no visible lesion to within the lesion in 3 cases, and from adjacent to the lesion to within the lesion in 12 cases. The positioning of the r-EBUS probe in relation to the lesions improved significantly with UTB usage (Z=-4.46, P<0.001). Localization rates (number of patients with "within" or "adjacent to" the image/total number of patients) for UTB and CB were 92.30% (36/39) and 66.67% (26/39), respectively (χ2=8.10, P=0.002). UTB improved r-EBUS probe localization rates. The diagnostic yields of UTB were higher than CB for solid lesions, lesions>30 mm in diameter, non-upper lobar location, benign or malignant lesions and lesions with or without a bronchus sign. Conclusion: The UTB group demonstrated a significantly higher diagnostic yield than the CB group, providing superior r-EBUS probe images, and a significant diagnostic advantage for PPL.

Abstract
Objective: To investigate the associations of onset age, diabetes duration, and glycated hemoglobin (HbA1c) levels with ischemic stroke risk in type 2 diabetes patients. Methods: The participants were from Comprehensive Research on the Prevention and Control of the Diabetes in Jiangsu Province. The study used data from baseline survey from December 2013 to January 2014 and follow-up until December 31, 2021. After excluding the participants who had been diagnosed with stroke at baseline survey and those with incomplete information on onset age, diabetes duration, and HbA1c level, a total of 17 576 type 2 diabetes patients were included. Cox proportional hazard model was used to calculate the hazard ratio (HR) and 95%CI of onset age, diabetes duration, and HbA1c level for ischemic stroke. Results: During the median follow-up time of 8.02 years, 2 622 ischemic stroke cases were registered. Multivariate Cox proportional risk regression model showed that a 5-year increase in type 2 diabetes onset age was significantly associated with a 5% decreased risk for ischemic stroke (HR=0.95, 95%CI: 0.92-0.99). A 5-year increase in diabetes duration was associated with a 5% increased risk for ischemic stroke (HR=1.05, 95%CI: 1.02-1.10). Higher HbA1c (per 1 standard deviation increase:HR=1.17, 95%CI: 1.13-1.21) was associated with an increased risk for ischemic stroke. Conclusion: The earlier onset age of diabetes, longer diabetes duration, and high levels of HbA1c are associated with an increased risk for ischemic stroke in type 2 diabetes patients.

Abstract
In recent years, significant advancements have been made in the synthesis and application of 1,3-dienes. This specific structural motif has garnered significant attention from researchers in materials science and biology due to its unique aggregation-induced emission (AIE) properties and extensive conjugation systems. The luminescent characteristics of these compounds are notably influenced by the geometry of the two double bonds. Therefore, it is essential to consolidate stereoselective synthetic strategies for 1,3-dienes. This comprehensive review seeks to elucidate the diverse techniques employed to attain stereo-control in the synthesis of 1,3-diene-based AIE luminogens (AIEgens). Particular emphasis is placed on comprehending the determinants of stereoselectivity and exploring the array of substrates amenable to these methods. Furthermore, the review underscores the AIE properties exhibited by these compounds and their extensive utility in organic light-emitting diodes (OLEDs), stimuli-responsive materials, sensors, bioimaging, and photodynamic therapy (PDT).

Abstract
Objective: To evaluate the incidence and case fatality rate of cardiovascular disease (CVD) among populations in urban and rural communities in eastern, central and western regions of China. Methods: The present study was based on the data of the Prospective Urban and Rural Epidemiology (PURE)-China cohort, which enrolled participants who had at least one follow-up visit and complete information on age and sex. Information on baseline demographics, cardiovascular risk factors, and prevention and treatment for CVD were collected. CVD and mortality events were documented using the standardized case report form of the PURE Global Study to assess the incidence and case fatality rate of CVD among populations in urban and rural communities in eastern, central and western China. Results: This study included a total of 47 262 community-dwelling participants (age: (51.1±9.6) years; female, n=27 529, 58.2%) from 115 urban and rural communities in 12 provinces across the eastern, central, and western regions of China. Over a follow-up period of 11.9 (9.5, 12.6) years, 2 686 deaths and 5 873 cardiovascular events were documented. The incidence of CVD was 11.90 (95%CI: 11.60-12.21)/1 000 person-years. A significant difference in CVD incidence was observed across regions (Ptrend<0.001), which was highest in the western provinces (13.99 (95%CI: 13.33-14.65)/1 000 person-years), intermediate in the eastern provinces (11.92 (95%CI: 11.52-12.33)/1 000 person-years), and lowest in the central provinces (8.87 (95%CI: 8.25-9.50)/1 000 person-years). The 1-year case fatality rate of CVD demonstrated an increasing trend from eastern to western regions (eastern: 10.20% (95%CI: 6.95-14.73); central: 13.50% (95%CI: 9.90-18.14); western: 18.62% (95%CI: 14.95-22.94); Ptrend<0.001). Moreover, the incidence of major CVD was consistently higher in rural areas compared with urban areas across eastern (P<0.001), central (P=0.01) and western (P<0.001)_regions, respectively. The 1-year case fatality rate in rural areas was also significantly higher compared with that in urban areas in both eastern (P<0.001) and western regions (P=0.02). Conclusions: The incidence and case fatality rate of CVD were high among middle-aged population in China, especially those in western regions with low socioeconomic levels and in rural areas.

Abstract
Background Robotic assistance in thyroidectomy is a developing field that promises enhanced surgical precision and improved patient outcomes. This study investigates the impact of the da Vinci Surgical System on operative efficiency, learning curve, and postoperative outcomes in thyroid surgery. Methods We conducted a retrospective cohort study of 104 patients who underwent robotic thyroidectomy between March 2018 and January 2022. We evaluated the learning curve using the Cumulative Sum (CUSUM) analysis and analyzed operative times, complication rates, and postoperative recovery metrics. Results The cohort had a mean age of 36 years, predominantly female (68.3%). The average body mass index (BMI) was within the normal range. A significant reduction in operative times was observed as the series progressed, with no permanent hypoparathyroidism or recurrent laryngeal nerve injuries reported. The learning curve plateaued after the 37th case. Postoperative recovery was consistent, with no significant difference in hospital stay duration. Complications were minimal, with a noted decrease in transient vocal cord palsy as experience with the robotic system increased. Conclusion Robotic thyroidectomy using the da Vinci system has demonstrated a significant improvement in operative efficiency without compromising safety. The learning curve is steep but manageable, and once overcome, it leads to improved surgical outcomes and high patient satisfaction. Further research with larger datasets and longer follow-up is necessary to establish the long-term benefits of robotic thyroidectomy.

Abstract
Objective: To evaluate the efficacy and safety of chimeric antigen receptor T-cell (CAR-T) therapy followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with Ph-like acute lymphoblastic leukemia (Ph-ALL) . Methods: Patients with Ph-ALL who underwent CAR-T therapy followed by allo-HSCT from March 2018 to August 2023 at the First Affiliated Hospital of Soochow University were included, and their clinical data were retrospectively analyzed. Results: Of the 21 patients, 14 were male and 7 were female. The median age at the time of CAR-T therapy was 22 (6-50) years. Seven patients had ABL1-like rearrangements, and 14 had JAK-STAT rearrangements. Prior to CAR-T therapy, 12 patients experienced hematologic relapse; 7 were multiparameter flow cytometry minimal residual disease (MFC-MRD) -positive and 2 were MFC-MRD-negative. CAR-T cells were derived from patients' autologous lymphocytes. Nine patients were treated with CD19 CAR-T cells, and 12 were treated with CD19/CD22 CAR-T cells. After assessment on day 28 after CAR-T therapy, 95.2% of the patients achieved complete remission, with an MRD-negative remission rate of 75%. Nineteen patients developed grade 0-2 cytokine release syndrome (CRS) and 2 patients suffered grade 3 CRS, all cases of which resolved after treatment. All patients underwent allo-HSCT after CAR-T therapy. The median time from CAR-T therapy to allo-HSCT was 63 (38-114) days. Five patients experienced relapse after CAR-T therapy, including four with hematologic relapse and one with molecular relapse. The 3-year overall survival (OS) rates in the ABL1 and JAK-STAT groups were (83.3±15.2) % and (66.6±17.2) %, respectively (P=0.68) . The 3-year relapse-free survival (RFS) rates were (50.0±20.4) % and (55.6±15.4) % in the ABL1 and JAK-STAT groups, respectively. There was no significant difference in 3-year OS or RFS between the two groups. Conclusions: CAR-T therapy followed by allo-HSCT leads to rapid remission in most patients with Ph-ALL and prolongs leukemia-free survival.

Abstract
Malignant tumors in children are one of the most important diseases that threaten the health and quality of life of children and are the second most common cause of death in children.With the continuous improvement and progress of treatment technology, the long-term survival rate of children with tumor has been significantly improved, but both the disease itself and the treatment can impair the immune function of children, which makes them vulnerable to various infectious diseases and secondary serious complications, and even become a source of infection, endangering the health of others. Vaccination is the most cost-effective measure to prevent infectious diseases. For children with normal immune functions, the benefits of vaccination usually outweigh the disadvantages. However, there is a lack of detailed data on the vaccination situation, efficacy and safety of vaccine use for such immunocompromised tumor survivors, and there are no authoritative and uniform vaccination recommendations. This article reviewed and summarized the literature and consensus of some domestic and foreign scholars on current status of post-treatment vaccination status, efficacy and safety of vaccination for children with tumors after treatment, with the aim of providing a reference for the practice in this field in China.

Abstract
Objective: To clarify the efficacy and safety of endoscopic submucosal dissection (ESD) with additional radiotherapy in T1a-MM/T1b-SM esophageal squamous cell carcinoma (ESCC). Methods: A retrospective analysis was conducted on 71 patients with T1a-MM/T1b-SM ESCC admitted to Southeast University Affiliated Zhongda Hospital from January 2015 to December 2019. The patients were divided into two groups based on the treatment method: the ESD group (ESD therapy alone) and the ESD-radiotherapy group (ESD combined radiotherapy). The follow-up duration after ESD was (44±17) months. The difference of disease-free survival (DFS) rate and overall survival (OS) rate between the two groups was compared by survival analysis, and the occurrence of complications was compared. Baseline variables of the two groups were compared and the influencing factors of DFS rate were analyzed by Cox proportional risk regression model. Results: There were 44 patients in the ESD-radiotherapy group [28 males, 16 females, aged (65±7) years] and 27 patients in the ESD group [18 males, 9 females, aged (67±9) years]. The results of survival analysis show that the 1, 3 and 5-year DFS rates of ESD-radiotherapy group were 95.5%, 92.9% and 77.4%, respectively, which were higher than those of ESD group 85.2%, 73.2% and 62.7% (all P<0.05). The 1, 3 and 5-year OS rates of the ESD-radiotherapy group were 100%, 94.7% and 94.7%, while those of the ESD group were 96.3%, 96.3% and 79.4%, respectively. The difference was not statistically significant (all P>0.05). Cox proportional hazard regression model analysis showed that ESD combined with radiotherapy (HR=0.19, 95%CI: 0.04-0.90, P=0.037), complete tumor resection (HR=0.25, 95%CI: 0.07-0.86, P=0.027), and vascular invasion (HR=12.06, 95%CI: 1.61-90.26, P=0.015) were the influencing factors of DFS rates. The most common complication of ESD was esophageal stenosis, and no grade 3 or higher radiation adverse reactions occurred after combined radiotherapy. Conclusion: ESD combined radiotherapy is an effective and safe therapeutic strategy for patients with T1a-MM/T1b-SM ESCC.

Abstract
Cancer stands as a serious malady, posing substantial risks to human well-being and survival. This underscores the paramount necessity to explore and investigate novel antitumor medications. Nitrogen-containing compounds, especially those derived from natural sources, form a highly significant category of antitumor agents. Among these, antitumor agents with six-membered aromatic nitrogen heterocycles have consistently attracted the attention of chemists and pharmacologists. Accordingly, we present a comprehensive summary of synthetic strategies and clinical implications of these compounds in this review. This entails an in-depth analysis of synthesis pathways for pyridine, quinoline, pyrimidine, and quinazoline. Additionally, we explore the historical progression, targets, mechanisms of action, and clinical effectiveness of small molecule inhibitors possessing these structural features.

Abstract
The vaginal microbiota is a complex and dynamic environment that plays an important role in the healthy reproduction of women. The mechanism of unexplained infertility is not yet clear, and the imbalance and low stability of vaginal microbiota may be related to unexplained infertility. Taking probiotic composite preparations to restore normal vaginal microbiota may be a safe and natural method for treating unexplained infertility. This article reviews the probiotic composite preparations used in the treatment of unexplained infertility both domestically and internationally, including the isolation site of the bacterial species, the use method of the composite preparation, the course of treatment, and the final therapeutic effect, aiming to provide a basis for the clinical application of probiotic composite preparations in the treatment of unexplained infertility.

Abstract
Hydrogen sulfide (H2S) promotes microangiogenesis and revascularization after ischemia. Neovascularization starts with the destruction of intercellular junctions and is accompanied by various endothelial cell angiogenic behaviors. Follistatin-like 1 (FSTL1) is a cardiovascular-protective myokine that works against ischemic injury. The present study examined whether FSTL1 was involved in H2S-induced angiogenesis and explored the underlying molecular mechanism. We observed that H2S accelerated blood perfusion after ischemia in the mouse hindlimb ischemia model. Western blot analysis showed that H2S stabilized FSTL1 transcript and increased FSTL1 and Human antigen R (HuR) levels in skeletal muscle. RNA-interference HuR significantly inhibited the H2S-promoted increase in FSTL1 levels. Exogenous FSTL1 promoted the wound-healing migration of human umbilical vein endothelial cells (HUVECs) and increased monolayer endothelial barrier permeability. Immunostaining showed that FSTL1 increased interendothelial gap formation and decreased VE-Cadherin, Occludin, Connexin-43, and Claudin-5 expression. In addition, FSTL1 significantly increased the phosphorylation of Src and VEGFR2. However, the Src inhibitor, not the VEGFR2 inhibitor, could block FSTL1-induced effects in angiogenesis. In conclusion, we demonstrated that H2S could upregulate the expression of FSTL1 by increasing the HuR levels in skeletal muscle, and paracrine FSTL1 could initiate angiogenesis by opening intercellular junctions via the Src signaling pathway.NEW & NOTEWORTHY The myocyte-derived paracrine protein FSTL1 acts on vascular endothelial cells and initiates the process of angiogenesis by opening the intercellular junction via activating Src kinase. H2S can significantly upregulate FSTL1 protein levels in skeletal muscles by increasing HuR expression.

Abstract
Objective: To explore the risk factors of rebleeding in patients with obscure gastrointestinal bleeding (OGIB) after capsule endoscopy (CE), and construct a model to predict rebleeding. Methods: The data of patients with OGIB who underwent CE in Zhongda Hospital Affiliated to Southeast University from July 2018 to September 2021 were retrospectively analyzed. Follow-up data were obtained via electronic medical records or telephone interviews. Univariate and multivariate Cox regression models were performed to figure out the risk factors of rebleeding in OGIB patients. Then the optimal prediction model was determined and presented as a nomogram. The model was evaluated by C statistic, calibration curve and decision curve analysis. Results: One hundred and thirty patients with OGIB were included, including 64 females and 66 males, aged (55.8±17.2) years (18-87 years), and 39 (30.0%) cases developed rebleeding during follow-up. Univariate and multivariate Cox regression model analysis showed the duration of more than 2 weeks OGIB (HR=3.70, 95%CI: 1.85-7.42, P<0.001), a history of previous gastrointestinal bleeding (HR=5.25, 95%CI: 2.00-13.81, P<0.001), positive CE findings (HR=3.72, 95%CI: 1.66-8.33, P=0.001), and the lowest hemoglobin level before CE<80 g/L (HR=2.00, 95%CI: 1.02-3.84, P=0.044) were risk factors for rebleeding, while specific treatment (HR=0.25, 95%CI: 0.11-0.54, P<0.001) was a protective factor. The corresponding scores of the above five predictive factors were: OGIB duration>2 weeks: 79 points; Previous history of gastrointestinal bleeding: 100 points; The result of CE was positive: 79 points; Specific treatment:-85 points; Minimum hemoglobin before CE<80 g/L: 41 points. The prediction model constructed from the above five variables had good discriminative capability (concordance index=0.798, 95%CI: 0.732-0.865). The calibration curves showed high consistency between nomogram-predicted probabilities and actual observations. The decision curves showed that when the threshold probability was above 0.04, the use of the nomogram to predict rebleeding provided a greater net benefit than the assumption of "all patients rebleeding or no patients rebleeding". Conclusion: The prediction model established in this study has a good ability to predic rebleeding in patients with OGIB after CE examination.

Abstract
Rationale Idiopathic hypogonadotropic hypogonadism (IHH) is a prevalent congenital genetic disorder with multiple inheritance patterns. IHH can manifest as normal hypogonadotrophic sexual hypofunction (nIHH) or with an abnormal sense of smell, known as Kallmann. It primarily affects the production and effectiveness of gonadotropin-releasing-hormone (GnRh), leading to reduced follicle-stimulating hormone and luteinizing hormone levels. This results in infertility and underdeveloped secondary sexual characteristics. Patient Concerns A 29-year-old female presented with infertility. Diagnosis IHH diagnosis was confirmed through magnetic resonance (MR) scan, endocrine tests, physical examination, and B ultrasonic inspection. Additionally, genetic studies, including chromosome analysis, were conducted for the patient. The results confirmed no genetic abnormalities or concerns. Interventions The patient underwent multiple ovulation induction programs. Outcome After several ovulation induction cycles, the patient conceived and delivered a live baby. Lessons For IHH patients, a tailored human menopausal gonadotropin (HMG) dose is recommended. High-dose HMG can benefit those with poor follicular response. The addition of letrozole (5-7.5mg) may enhance follicular response during stimulation. Our approach, which emphasizes the combined use of high-dose HMG, letrozole, and the adjustment of FSH and LH ratios, offers a unique perspective compared to traditional treatments. If HMG treatment is ineffective, alternative ovulation induction methods, such as r-fsh combined with r-lh or HMG combined with rLH, can be considered. Adjusting the FSH and LH ratio and varying rFSH and rLH additions might help achieve dominant follicles and live birth in resistant cases. This case report underscores the potential benefits of our regimen, suggesting its consideration for future research and clinical applications.

Abstract
Objective: This study aims to explore the causal relationship between obstructive sleep apnea (OSA) and type 2 diabetes (T2D) using bidirectional Mendelian randomization (MR). Methods: The genetic data related to OSA were obtained from the FinnGen Biobank (Ncase=16, 761, Ncontrol=201, 194) in the Genome-wide association study (GWAS). Three single nucleotide polymorphism (SNP) were screened out as instrumental variable (IV) of OSA. The genetic data related to T2D were derived from a large Meta-analysis of GWAS (Ncase=62, 892, Ncontrol=596, 424), 114 SNP were selected as IV of T2D. Multiple MR methods were used for analysis and inverse variance weighted (IVW) was performed as main method. The sensitivity of MR analytic results was analyzed using MR-Egger and other methods, and the IV was evaluated using F-value statistics. Results: MR analysis showed that OSA was significantly associated with increased risk of T2D (OR=2.016, 95%CI: 1.185-3.429, P<0.05). There was no significant relationship between T2D and OSA risk (OR=1.030, 95%CI: 0.980-1.082, P=0.238). There was heterogeneity in both-way results (OSA➝T2D, P=1.808×10-11; T2D➝OSA, P=1.729×10-7), and no horizontal pleiotropy (OSA➝T2D, P=0.477; T2D➝OSA, P=0.349). IV of OSA and T2D-selected in the study were strong instrumental variables (F statistics of OSA=20.543; F statistics of T2D=30.117). Conclusion: Our results supported that OSA was a risk factor for T2D, but T2D had no significant impact on the incidence of OSA. Blood glucose monitoring and diabetes screening in OSA patients might be beneficial to the early detection and intervention of T2D.

Abstract
BACKGROUND For female breast cancer patients, the psychological status after surgery, especially the social and family psychological-related factors, deserves more attention. This study analyzed the influence of social constraints, social support, social isolation, family conflict, and family emotion expression on depression. At the same time, this study conducted the relationship between the variables and the mechanism of action. METHODS We conducted a cross-sectional study and 522 breast cancer patients finished questionnaires consisting of Self-Rating Depression Scale (SDS), General Self-Efficacy Scale (GSES), Multi-Dimensional Scale of Perceived Social Support (MSPSS), Social Constraints Scale-5 (SCS-5), Family Environment Scale (FES), and Lubben Social Network Scale (LSNS-6). Multivariable logical regression was used to explore influencing factors. Pearson's correlation, hierarchical regression, and simple slope analysis were conducted to verify the role of self-efficacy. RESULTS 71.6% of patients had depressive symptoms. Family contradiction (OR = 10.086), social constraints (OR = 2.522), social isolation (OR = 2.507), and high blood glucose (OR = 2.156) were risk factors of depressive symptoms. Family emotional expression (OR = 0.480), family intimacy (OR = 0.235), and self-efficacy (OR = 0.246) were protective factors against depressive symptoms. The interactive items interpretation quantity were as follows: Contradiction*Self-efficacy (ΔR2 = 2.3%, P < 0.001), Emotional expression*Self-efficacy (ΔR2 = 2.6%, P < 0.001), Intimacy*Self-efficacy (ΔR2 = 1.0%, P = 0.018), Social constraints*Self-efficacy (ΔR2 = 1.0%, P = 0.008), Social networks*Self-efficacy (ΔR2 = 1.0%, P = 0.010), Blood Glucose*Self-efficacy (ΔR2 = 0.6%, P = 0.023). The influence of independent variables on depressive symptoms was gradually decreased in the low, mean, and high groups of self-efficacy. CONCLUSION Postoperative Chinese breast cancer survivors reported higher depressive symptoms. Social, family, and physiological factors could affect depressive symptoms, in which self-factor played moderator roles.

Abstract
Objective: To explore the efficacy and safety of Venetoclax combined with multidrug chemotherapy in patients with relapsed or refractory early T-cell precursor acute lymphoblastic leukemia (R/R ETP-ALL) . Methods: This study retrospectively analyzed 15 patients with R/R ETP-ALL who received Venetoclax combined with multidrug chemotherapy from December 2018 to February 2022. Among them, eight cases were combined with demethylated drugs, four cases were combined with demethylated drugs and HAAG chemotherapy regimen, two cases were combined with demethylated drugs and CAG regimen, and one case was combined with Cladribine. Specific usage and dosage of Venetoclax: 100 mg on day 1, 200 mg on day 2, 400 mg on day 3-28, orally; when combined with azole antifungal drugs, dosage was reduced to 100 mg/d. Results: Fifteen patients (10 males and 5 females) with R/R ETP-ALL were treated with Venetoclax and multidrug chemotherapy with a median age of 35 (12-42) years old. Of 4 refractory and 11 relapsed patients, the efficacy was evaluated on the 21th day following combined chemotherapy: the overall response rate, the complete response (CR) rate, and the CR with incomplete hematological recovery (CRi) rate were 67.7% (10/15), 60.0% (9/15), and 6.7% (1/15), respectively. For the overall study population, the 12-month overall survival (OS) rate was 60.0%, and the median OS was 17.7 months. The disease-free survival (DFS) rate of all CR patients at 12 months was 60.0%, and the median DFS did not reach. About 14 patients had Ⅲ-Ⅳ hematological toxicity, but these adverse reactions were all controllable. No adverse reaction in the nervous system and tumor lysis syndrome occurred in this study, and no adverse reaction of organs above grade Ⅲ occurred. Conclusion: Venetoclax combined with multidrug chemotherapy may be a safe and promising treatment option for patients with R/R ETP-ALL.

Abstract
Schizophrenic and pregnant smokers with tobacco dependence had always been excluded from most large treatment trials for nicotine dependence. As weight gain was found to be common after smoking cessation, obese people were more likely to have a reduced willingness to quit smoking and an increased risk of relapse. This article reviewed the latest research progress in pharmacological treatment of tobacco dependence in schizophrenia, pregnant women, and obese people.

Abstract
The present study examines whether there is a mechanism beyond the current concept of post-translational modifications to regulate the function of a protein. A small gas molecule, hydrogen sulfide (H2S), was found to bind at active-site copper of Cu/Zn-SOD using a series of methods including radiolabeled binding assay, X-ray absorption near-edge structure (XANES), and crystallography. Such an H2S binding enhanced the electrostatic forces to guide the negatively charged substrate superoxide radicals to the catalytic copper ion, changed the geometry and energy of the frontier molecular orbitals of the active site, and subsequently facilitated the transfer of an electron from the superoxide radical to the catalytic copper ion and the breakage of the copper-His61 bridge. The physiological relevance of such an H2S effect was also examined in both in vitro and in vivo models where the cardioprotective effects of H2S were dependent on Cu/Zn-SOD.

Abstract
Primary bovine intestinal epithelial cells (PBIECs) are an important model for studying the molecular and pathogenic mechanisms of diseases affecting the bovine intestine. It is difficult to obtain and grow PBIECs stably, and their short lifespan greatly limits their application. Therefore, the purpose of this study was to create a cell line for exploring the mechanisms of pathogen infection in bovine intestinal epithelial cells in vitro. We isolated and cultured PBIECs and established an immortalized BIEC line by transfecting PBIECs with the pCI-neo-hTERT (human telomerase reverse transcriptase) recombinant plasmid. The immortalized cell line (BIECs-21) retained structure and function similar to that of the PBIECs. The marker proteins characteristic of epithelial cells, cytokeratin 18 (CK18), occludin, zonula occludens protein 1 (ZO-1), E-cadherin and enterokinase, were all positive in the immortalized cell line, and the cell structure, growth rate, karyotype, serum dependence and contact inhibition were normal. The hTERT gene was successfully transferred into BIECs-21 where it remained stable and was highly expressed. The transport of short-chain fatty acids and glucose uptake by the BIECs-21 was consistent with PBIECs, and we showed that they could be infected with the intestinal parasite, Neospora caninum. The immortalized BIECs-21, which have exceeded 80 passages, were structurally and functionally similar to the primary BIECs and thus provide a valuable research tool for investigating the mechanism of pathogen infection of the bovine intestinal epithelium in vitro.

Abstract
Background Gonadotropin-releasing hormone antagonists (GnRH-ant) are widely used in current in vitro fertilization-embryo transfer (IVF-ET), however, whether the lowest daily dose of GnRH-ant is individualized remains unknown. Due to the negative effect of GnRH-ant on endometrial receptivity, lessening the amount of GnRH-antagonists used during controlled ovarian stimulation may be helpful for embryo implantation. As such, a randomized controlled study is essential to validate the feasibility and efficacy of daily GnRH-ant dose reduction to 0.125 mg geared towards providing scientific evidence for guidance in clinical practice. Methods In total, 620 infertile women undergoing in vitro fertilization will be enrolled in the multicentered, randomized, parallel controlled trial. Based on a computer-generated random list, they will be randomly and equally subdivided into half-dose GnRH-ant group or conventional-dose GnRH-ant group. The primary outcome is ongoing pregnancy ie, intrauterine pregnancy diagnosed by pelvic ultrasonography at more than 12 weeks of gestation accompanied by normal fetal heartbeats. Secondary outcomes include cycle cancellation, premature luteinizing hormone surge, positive pregnancy, embryo implantation rate, clinical pregnancy, early spontaneous abortion, and live birth. The intention-to-treat and per protocol analyses will be used to initially analyze the difference in ongoing pregnancy rate between the two groups, while the multiple imputation method was used to handle missing values in the data. Discussion At present, no randomized controlled trials (RCTs) have been performed on the use of the half-dose GnRH-ant protocol (0.125mg/d) to improve reproductive outcomes of IVF-ET in predicted normal responder, compared to conventional-dose GnRH-ant protocol (0.25mg/d). Half-dose GnRH-ant protocol might provide a suitable clinical solution for predicted normal responder undergoing IVF treatment. Thus, it is critical to conduct a well-designed RCT to evaluate the impact of a half-dose GnRH-ant protocol on the reproductive outcomes of IVF-ET in predicted normal responder. Trial Registration This study was registered in the Chinese Clinical Trials Registry Platform on August 29, 2020. (chictr.org.cn; identifier: ChiCTR2000037629). This trial is version 1.3.

Abstract
Biological aqua crust (BAC), as a novel biological crust with high arsenic (As) immobilization capacity, might be an ideal nature-based solution for As removal in mine drainage. This study examined the As speciation, binding fraction and biotransformation genes in the BACs to find out the underlying mechanism of As immobilization and biotransformation. Results showed that the BACs could immobilize As from mine drainage up to 55.8 g/kg, and their As immobilization concentrations were 1.3-6.9 times higher than that of sediments. Extremely high As immobilization capacity was attributed to the processes of bioadsorption/absorption and biomineralization driven by Cyanobacteria. The high abundance of As(III) oxidation genes (27.0 %) enhanced microbial As(III) oxidation, resulting in >90.0 % of As(V) with low toxicity and mobility in the BACs. The increase in abundances of aioB, arsP, acr3, arsB, arsC and arsI with As was the key process for microbiota in the BACs for resistance to the As toxicity. In conclusion, our findings innovatively confirmed the potential mechanism of As immobilization and biotransformation mediated by the microbiota in the BACs and highlighted the important role of BACs for As remediation in mine drainage.

Abstract
BACKGROUND Papillary thyroid cancer (PTC) is one of the well-differentiated thyroid tumors. Cutaneous metastasis from differentiated thyroid cancers occurs in < 1% of primary thyroid carcinomas but produces the worst survival prognosis. The multi-targeting tyrosine kinase inhibitor anlotinib has been approved to treat refractory advanced non-small-cell lung cancer as well as advanced soft-tissue and clear cell sarcomas in China.
CASE SUMMARY In a patient with scalp metastasis caused by PTC, thyroid and skull metastasis tumor sizes were significantly reduced after a trial of neoadjuvant anlotinib therapy for 3 cycles. Anlotinib maintenance medication after thyroidectomy further reduced the metastatic skull tumor size thereby preventing the requirement for craniotomy.
CONCLUSION The outcome of the present trial confirmed the potential of anlotinib therapy to treat scalp metastasis induced by PTC and point the way for the treatment of similar diseases in the future.

Abstract
The original description and outline figure of the mayfly Ephemera pieli Navás, 1934, were based on male subimagoes, and its morphology and taxonomic status have not been confirmed since then. However, recently collected materials from eastern China, including all stages of this mayfly, reveal several unique characteristics that indicate E. pieli is a valid species in the subgenus Ephemera (Ephemera). These characteristics include forewings with numerous dark dots, hindwings or hind wingpads with one or two distinct median dots, penes covered mostly by the subgenital plate, and the apex of the penis bluntly extended. A neotype is designated.

Abstract
Objective: To analyze the burden of disease attributable to high temperature exposure in China and globally from 1990 to 2019, and to study the current burden of disease in relevant populations. Methods: In October 2021, based on data from the global burden of disease 2019 (GBD 2019) study, population attributable fraction (PAF), number of deaths, mortality, disability-adjusted life year (DALY) and DALY rate of Chinese and global populations with different ages and genders in 1990 and 2019 were extracted and analyzed. The rate of change was calculated, the mortality rate was normalized by the age structure of the world standard population, and the causes of disease burden caused by high temperature exposure of Chinese residents were analyzed. Results: In 2019, compared with 1990, the PAF of Chinese and global population decreased by 43.98% and 12.41% respectively, the number of deaths increased by 29.55% and 49.40% respectively, the crude mortality rate increased by 7.81% and 3.30% respectively, the DALY decreased by 48.12% and 14.41% respectively, and the DALY rate decreased by 56.82% and 40.82% respectively. The mortality rate of the ≥70 age group was higher than that of other groups. The disease burden indicators such as PAF, standardized mortality and DALY attributable to high temperature exposure in men were higher than those in women. In 2019, the main cause of DALY affected by high temperature exposure in Chinese population was ischemic heart disease (84400 person-years), and the main cause of death was ischemic heart disease (4900 cases). Conclusion: The burden of diseases attributable to high temperature exposure is still serious in China and the world at large. Targeted interventions should be formulated for men, the elderly and people with occupational exposure, and a sound surveillance system should be established to reduce the burden of diseases caused by high temperature exposure.

Abstract
In 2001, Rutledge reported the first case of mini gastric bypass (MGB). Carbajo improved the technique of MGB and named it one anastomosis gastric bypass (OAGB). Over the past 20 years, a large number of clinical and basic studies on OAGB/MGB have been reported, and the answers to some key questions about OAGB/MGB have gradually become clear. From a technical point of view, MGB and OAGB can be regarded as two subvariants of one surgery. The advantages of OAGB/MGB include: (1) simplicity, safety and lower probability of internal hernia;(2) stable and durable weight reduction effect; (3) stable and durable remission rate of type 2 Diabetes. The disadvantages of OAGB/MGB include: (1) bile reflux; (2) higher risk of malnutrition. OAGB/MGB has achieved a good balance between effectiveness and safety, and has become the most noticed and fastest-growing bariatric and metabolic procedure in recent years. OAGB/MGB has been recommended as a standard bariatric and metabolic procedure by IFSO and ASMBS.

Abstract
Objective: To understand the epidemiological characteristics of a local clustered epidemic caused by 2019-nCoV Delta variant in Ningbo and provide reference for the improvement of COVID-19 epidemic prevention and control. Methods: Case finding was conducted based on case definitions, and field epidemiological investigation of COVID-19 cases was carried out. In which Nasal and oropharyngeal swabs of the cases were collected for pathogen testing, and the results were analyzed with descriptive epidemiological methods. Results: A total of 74 COVID-19 cases were reported in this epidemic, and the cases were mainly mild ones, accounting for 87.84% (65/74), and there were no severe or critical cases. The epidemic curve showed a human-to-human transmission mode, indicating that a transmission for at least six generations had occurred. The age of the COVID-19 patients ranged from 2 years to 80 years, and 27.03% (20/74) of the cases were older than 60 years. The cases were mainly workers (55.41%, 41/74) and housework/the unemployed (27.03%, 20/74). The COVID-19 epidemic was limited, and no further spread to other areas occurred. The transmission chain among the cases was clear, and the gene sequencing results confirmed that the current epidemic was caused by 2019-nCoV Delta variant, which was highly homologous to the strains from other province. Conclusion: The local COVID-19 epidemic in Ningbo was caused by imported cases of COVID-19 from other province, and local community spread occurred through daily contacts between cases and contacts.

Abstract
Objective: To investigate the association between peripheral blood mitochondrial DNA copy number (mtDNAcn) and incident risk of liver cancer. Methods: At the baseline of Dongfeng-Tongji (DFTJ) cohort, 27 009 retirees were recruited from Dongfeng Motor Corporation in 2008. After excluding people without baseline DNA, with current malignant tumor and loss of follow-up, 1 173 participants were randomly selected into a sub-cohort by age-and gender-stratified sampling method at a proportion of 5% among all retirees. A total of 154 incident liver cancer cases identified from the cohort before December 31, 2018 (4 cases had been selected into the sub-cohort) were selected to form the case cohort of liver cancer. For the above 1 323 participants, their baseline levels of mtDNAcn in peripheral blood cells were measured by using quantitative real-time PCR method. The restricted cubic spline analysis was used to fit the shape of the association between baseline mtDNAcn and incident risk of liver cancer. The weighted Cox proportional hazards model was used to estimate the hazard ratio (HR) and 95%CI. Results: In this case-cohort study, the median follow-up time was 10.3 years. The restricted cubic spline analysis indicated that the relationship between peripheral blood mtDNAcn and incident risk of liver cancer followed a U-shaped pattern (Pnon-linear<0.05). All case-cohort population were divided into four subgroups by sex-specific quartiles of mtDNAcn levels among sub-cohort participants, when compared to participants in the Q2 subgroup of mtDNAcn, those in the Q1 subgroup (HR=2.00,95%CI:1.08-3.70) and Q4 subgroup (HR=4.11,95%CI:2.32-7.26) both had a significantly elevated risk of liver cancer, while those in the Q3 subgroup (HR=1.05,95%CI:0.54-2.05) had not. There were no significant multiply interaction effects of aging, gender, tobacco smoking, alcohol drinking and history of chronic hepatitis on the above association (Pinteraction>0.05). Conclusion: Both extremely low and high baseline level of mtDNAcn in peripheral blood cells are associated with an increased risk of incident liver cancer, but the underlying mechanisms need to be further clarified.

Abstract
Aims: The genes targeted by miRNAs have been well studied. However, little is known about the feedback mechanisms to control the biosynthesis of miRNAs that are essential for the miRNA feedback networks in the cells. In this present study, we aimed at examining how hydrogen sulfide (H2S) promotes angiogenesis by regulating miR-192 biosynthesis. Results: H2S promoted in vitro angiogenesis and angiogenesis in Matrigel plugs embedded in mice by upregulating miR-192. Knockdown of the H2S-generating enzyme cystathionine γ-lyase (CSE) suppressed in vitro angiogenesis, and this suppression was rescued by exogenous H2S donor NaHS. Plakophilin 4 (PKP4) served as a target gene of miR-192. H2S up-regulated miR-192 via the VEGFR2/Akt pathway to promote the splicing of primary miR-192 (pri-miR-192), and it resulted in an increase in both the precursor- and mature forms of miR-192. H2S translocated YB-1 into the nuclei to recruit Drosha to bind with pri-miR-192 and promoted its splicing. NaHS treatment promoted angiogenesis in the hindlimb ischemia mouse model and the skin-wound-healing model in diabetic mice, with upregulated miR-192 and downregulated PKP4 on NaHS treatment. In human atherosclerotic plaques, miR-192 levels were positively correlated with the plasma H2S concentrations. Innovation and Conclusion: Our data reveal a role of YB-1 in recruiting Drosha to splice pri-miR-192 to mediate the proangiogenic effect of H2S. CSE/H2S/YB-1/Drosha/miR-192 is a potential therapeutic target pathway for treating diseases, including organ ischemia and diabetic complications. Antioxid. Redox Signal. 36, 760-783.

Abstract
Ascorbic acid (AsA) is an important nutrient in celery, the conversion of D-mannose-1-P to GDP-D-mannose catalyzed by GDP-D-mannose pyrophosphorylase (GMPase) represents the first committed step in the biosynthesis of AsA. To clarify the function of the AgGMP gene of celery, the AgGMP gene was cloned from celery cv. 'Jinnan Shiqin' . It contains an open reading frame (ORF) with the length of 1,086 bp, encoding 361 amino acids. AgGMP protein was highly conserved among different plant species. Phylogenetic analysis demonstrated that the GMP proteins from celery and carrot belonged to the same branch. AgGMP protein was mainly composed of three α-helixes and certain random coils. No signal peptide was found in the AgGMP protein. The subcellular localization indicated that the AgGMP protein was located in the cytoplasm. The relative expression levels of AgGMP in 'Jinnan Shiqin' were significantly up-regulated at 2 h and 4 h under drought stress treatments. AsA contents in transgenic Arabidopsis lines hosting AgGMP gene were higher than that in wild type plants, and the root lengths were also longer in the MS medium containing 300 mM mannitol. The present study provides useful evidence for the functional involvement of AgGMP in regulating AsA accumulation and response to drought stress in celery.

Abstract
We present an anomalous Josephson effect in a TI-based Josephson junction with a ferromagnetic insulator (FI) trilayer which has noncoplanar magnetizations. It is shown that there exist equal fractional spin-singlet and -triplet correlations due to the magnetism-tuning chiral Dirac energy band structure. The consequent anomalous Josephson supercurrent is exhibited, in which a 0-πor similar 0-πstate transition through phase shift is induced only by exchange field strength of the first FI region, while theϕ0supercurrent and the maximum one gradually drop with the increase of exchange field strengths of the second and third FI regions without relative state transitions. With the increase of the FI region length, theϕ0supercurrent and the maximum one are also both decreased, are found, which is different from the situation for increasing the exchange filed strength. In addition, the corresponding free energies are presented and discussed.

Abstract
The aim of this study was to construct a simple, rapid and ultra-sensitive optical biosensing technique based on rolling circle amplification (RCA), and to apply it to multiple detection of drug-resistant genes of mycobacterium tuberculosis. The common mutation sites of isoniazid, rifampicin and streptomycin resistance genes are katG315 (AGC➝ACC), rpoB531 (CAC➝TAC) and rpsL43 (AAG➝AGG). For these three gene sites, from February 2020 to May 2021, in the Department of Laboratory Medicine of the First Affiliated Hospital of Army Military Medical University, the padlock probe (PLP), primers and capture probes were designed. And a solid-phase RCA constant temperature amplification reaction system based on magnetic beads was constructed and the experimental parameters were optimized. The RCA products were accurately captured by the multicolor fluorescent probes (Cy3/Cy5/ROX), and the single-tube multiple detection of three mutation genes was realized. The sensitivity, specificity and linear range of this method were further verified. The results showed that the response range of katG315 in the same reaction system ranged from 1.0 pmol/L to 0.1 nmol/L. The response range of rpoB531 and rpsL43 ranged from 1.0 pmol/L to 50.0 pmol/L and 1.0 pmol/L to 20.0 pmol/L, and the method had good specificity and sensitivity, and could accurately identify single base mutations in mixed targets, with the minimum detection limit as low as 1.0 pmol/L. The recoveries of simulated serum samples were 95.0%-105.2%. In conclusion, the constant temperature amplification multiple detection method constructed in this study can quickly realize the single-tube multiple detection of three drug resistance mutation sites. This technology is low-cost, simple and rapid, and does not rely on large equipment, providing a new analysis method for pathogen drug resistance gene detection.

Abstract
Objective: To compare the efficacy and safety of ticagrelor and clopidogrel in elderly Chinese patients with acute coronary syndrome (ACS) underwent percutaneous coronary intervention (PCI) in the real world. Methods: This study is a post-hoc analysis of a single center, retrospective cohort study. Between March 2016 and March 2018, elderly (age≥65) ACS patients who underwent PCI in the General Hospital of Northern Theater Command were included in the study. The patients were grouped according to P2Y12 receptor inhibitor. The primary endpoints of this study were ischemic events during the 2-year follow-up, which were defined as the composite of cardiac death, myocardial or stroke. The secondary efficiency endpoints included all-cause death and BARC 2, 3, 5 bleeding events. Results: A total of 4 022 elderly (mean age: (71.5±5.3) years) ACS patients were included in this study. Based on the choice of P2Y12 receptor inhibitor, patients were divided into clopidogrel (n=3 201) and ticagrelor (n=821) groups. Incidences of ischemic events (3.2% (26/821) vs. 5.6% (179/3 201), P=0.005) at 2 years were significantly lower in ticagrelor group compared to clopidogrel group. BARC 2, 3, 5 bleeding events (1.7% (14/821) vs. 1.6% (52/3 201), P=0.818) were comparable between the two groups. The incidence of all-cause death (1.5% (12/821) vs. 4.1% (132/3 201), P=0.005) were also lower in the ticagrelor group compared to the clopidogrel group. Clinical outcomes were consistent after adjusting for confounding factors, the incidence of ischemic events (HR= 0.637, 95%CI 0.409-0.991, P=0.046) and all-cause mortality (HR=0.402, 95%CI 0.213-0.758, P=0.005) was significantly lower in the ticagrelor group compared with the clopidogrel group. Risk of BARC 2, 3, 5 bleeding events were similar between the two groups (HR=0.957, 95%CI 0.496-1.848, P=0.897). Conclusion: In real-world clinical practice, for elderly patients with ACS undergoing PCI, ticagrelor use might reduce the incidence of long-term ischemic events and all-cause death without increasing the risk of bleeding.

Abstract
New food packaging has shown research significance in the face of increasing demand for high-quality foods and growing attention paid to food safety. In this study, ginger essential oil microcapsule composite films were prepared by combining microcapsules prepared by a complex coacervation method with gelatin films, and the mechanical properties and active functions of the composite films were analyzed. Fourier-transform infrared spectroscopy and differential scanning calorimetry confirmed the successful encapsulation of ginger essential oil. The scanning electron microscopy of the composite films showed the microcapsules and gelatin film matrix were highly compatible. During the entire storage period, the antioxidant capacity of the ginger essential oil microcapsule films weakened more slowly than ginger essential oil microcapsules and could be maintained at a relatively high level for a long time. The microcapsule films had excellent inhibitory effects on Escherichia coli, Staphylococcus aureus, and Bacillus subtilis. Therefore, the direct addition of microcapsules to a film matrix can broaden the application range of microcapsules and increase the duration of the release of active ingredients. Ginger essential oil microcapsule films are potential biodegradable food packaging films with long-lasting activity.

Abstract
目的 分析影响初治多发性骨髓瘤(NDMM)患者早期死亡(EM)的因素,建立其预测模型,以期识别EM风险。 方法 回顾性分析2009年5月至2017年1月吉林大学白求恩第一医院收治的275例NDMM患者,对6个月(EM6)、12个月(EM12)及24个月(EM24)内死亡患者初诊时基线特征进行单因素分析,并根据多因素分析结果建立EM的预测模型。 结果 本研究中EM6、EM12及EM24的发生率分别是5.5%、12.7%和30.2%;最常见的死亡原因为疾病复发/进展,在EM6、EM12及EM24中分别占60.0%、77.1%及84.3%。影响EM6的因素包括经白蛋白校正的血清钙(校正钙)>2.75 mmol/L和PLT<100×109/L;影响EM12的因素包括年龄>75岁、国际分期系统(ISS) Ⅲ期、修订版国际分期系统(R-ISS) Ⅲ期、校正钙>2.75 mmol/L、血清肌酐>177 µmol/L、PLT<100×109/L及骨髓浆细胞比例≥60%;影响EM24的因素中,除上述影响EM12的因素外,还包括男性和染色体核型1q+。多因素分析尚未发现EM6和EM12的独立预后因素。在EM24的多因素分析中,年龄>75岁、PLT<100×109/L和染色体核型1q+是EM24的独立预后因素。根据Logistic回归系数赋分:年龄>75岁:1分;PLT<100×109/L:2分;染色体核型1q+:1分,建立EM24预测模型,ROC曲线下面积为0.709(95%CI 0.626~0.793)。积分≥3分的患者24个月内死亡风险是0~2分患者的26倍,积分0~4分的NDMM患者中位总生存期分别为59、41、22、17.5及16个月(P<0.001)。 结论 年龄>75岁、PLT<100×109/L和染色体核型1q+为EM24的独立预后因素,依据上述变量构建的EM24预测模型有助于识别EM风险和预测生存,具有较好标准度与区分度。

Abstract
OBJECTIVES The postoperative risk factors for electroencephalogram(EEG) abnormalities after paediatric cardiopulmonary bypass (CPB) remain to be identified. We investigated the characteristics of EEG abnormalities and risk factors in routine clinical management post-CPB. METHODS EEG and cerebral oxygen saturation (ScO2) were monitored in 96 patients (aged 3 days, 37 months, median 5 months) for 72 h post-CPB. Clinical measurements included 4-hourly arterial and central venous pressure, arterial blood gases, doses of inotropic and vasoactive drugs, daily C-reactive protein (CRP) and NT-proB-type Natriuretic Peptide (NT-proBNP). Demographics, STAT categories and outcomes (duration of mechanical ventilation,CICU stay) were recorded. Un. RESULTS Seizures occurred in 20 patients (20.8%) beginning at 0-48 hand lasting 10 min-31 h; background abnormalities occurred in 67 (69.8%) beginning at 0-8 h and lasting 4-48 h. Patients with EEG abnormalities had worse outcomes. In univariable regression, seizures positively correlated with STAT categories, CPB time, temperature, blood pressure, central venous pressure, NT-proBNP, CRP, lactate and epinephrine, negatively with ScO2 and PaCO2 (P < 0.001 for lactate and epinephrine, P < 0.1 for the remaining). The degree of background abnormalities positively correlated with STAT categories, CPB time, operative time, central venous pressure, milrinone, negatively with blood pressure (P = 0.0003-0.087); it negatively correlated with lower dose of epinephrine (P < 0.001) and positively with higher dose (P = 0.03l). In multivariable regression, seizures positively correlated with epinephrine, lactate and temperature; the background abnormality correlations remain significant except for milrinone and operative time (P < 0.001 for epinephrine, P < 0.05 for the remaining). CONCLUSIONS Numerous perioperative risk factors are associated with EEG abnormalities post-CPB. The most significant and consistent risk factor is epinephrine.
