Abstract
Background Patients are increasingly using artificial intelligence (AI) chatbots to seek answers to medical queries. Methods Ten frequently asked questions in anaesthesia were posed to three AI chatbots: ChatGPT4 (OpenAI), Bard (Google), and Bing Chat (Microsoft). Each chatbot's answers were evaluated in a randomised, blinded order by five residency programme directors from 15 medical institutions in the USA. Three medical content quality categories (accuracy, comprehensiveness, safety) and three communication quality categories (understandability, empathy/respect, and ethics) were scored between 1 and 5 (1 representing worst, 5 representing best). Results ChatGPT4 and Bard outperformed Bing Chat (median [inter-quartile range] scores: 4 [3-4], 4 [3-4], and 3 [2-4], respectively; P<0.001 with all metrics combined). All AI chatbots performed poorly in accuracy (score of ≥4 by 58%, 48%, and 36% of experts for ChatGPT4, Bard, and Bing Chat, respectively), comprehensiveness (score ≥4 by 42%, 30%, and 12% of experts for ChatGPT4, Bard, and Bing Chat, respectively), and safety (score ≥4 by 50%, 40%, and 28% of experts for ChatGPT4, Bard, and Bing Chat, respectively). Notably, answers from ChatGPT4, Bard, and Bing Chat differed statistically in comprehensiveness (ChatGPT4, 3 [2-4] vs Bing Chat, 2 [2-3], P<0.001; and Bard 3 [2-4] vs Bing Chat, 2 [2-3], P=0.002). All large language model chatbots performed well with no statistical difference for understandability (P=0.24), empathy (P=0.032), and ethics (P=0.465). Conclusions In answering anaesthesia patient frequently asked questions, the chatbots perform well on communication metrics but are suboptimal for medical content metrics. Overall, ChatGPT4 and Bard were comparable to each other, both outperforming Bing Chat.

Abstract
The onset of Alzheimer's disease is related to neuron damage caused by massive deposition of Aβ in the brain. Recent studies suggest that excessive Aβ in the brain mainly comes from peripheral blood, and BBB is the key to regulate Aβ in and out of the brain. In this study, we explored the pathogenesis of AD from the perspective of Aβ transport through the BBB and the effect of QKL injection in AD mice. The results showed that QKL could improve the cognitive dysfunction of AD mice, decrease the level of Aβ and Aβ transporter-RAGE, which was supported by the results of network pharmacology, molecular docking and molecular dynamics simulation. In conclusion, RAGE is a potential target for QKL's therapeutic effect on AD.

Abstract
Background Spanish is the second most spoken language globally with around 475 million native speakers. We aimed to validate a Spanish version of the Obstetric Quality of Recovery-10 item (ObsQoR-10) patient-reported outcome measure. Methods ObsQoR-10-Spanish was developed using EuroQoL methodology. ObsQoR-10-Spanish was assessed in 100 Spanish-speaking patients undergoing elective Caesarean or vaginal delivery. Patients <38 weeks, undergoing an intrapartum Caesarean delivery, intrauterine death, or maternal admission to the intensive care unit (ICU) were excluded. Validity was assessed by evaluating (i) convergent validity-correlation with 24-h EuroQoL and global health visual analogue scale (GHVAS) scores (0-100); (ii) discriminant validity-difference in ObsQoR-10-Spanish score for patients with GHVAS scores >70 vs <70; (iii) hypothesis testing-correlation of ObsQoR score with maternal and neonatal factors; and (iv) cross-cultural validity assessed using differential item functioning analysis. Reliability was assessed by evaluating: (i) internal consistency; (ii) split-half reliability and (iii) test-retest reliability; and (iv) floor and ceiling effects. Results One hundred patients were approached, recruited, and completed surveys. Validity: (i) convergent validity: the ObsQoR 24-h score correlated moderately with the 24-h EuroQoL (r=-0.632) and GHVAS scores (r=0.590); (ii) discriminant validity: the ObsQoR-10-Spanish 24-h scores were higher in women who delivered vaginally compared to via Caesarean delivery, (mean [standard deviation] scores were 89 [9] vs 81 [12]; P<0.001). The 24-h ObsQoR-Spanish scores were lower in patients experiencing a poor vs a good recovery (mean [standard deviation] scores were 76 [12.3] vs 87.1 [10.6]; P=0.001); (iii) hypothesis testing: the ObsQoR-10 score correlated negatively with age (r=-0.207) and positively with 5-min (r=0.204) and 10-min (r=0.243) Apgar scores. Remaining correlations were not significant; and (iv) differential item functioning analysis suggested no potential bias among the 10 items. Reliability: (i) internal consistency was good (Cronbach alpha=0.763); (ii) split-half reliability was good (Spearman-Brown prophesy reliability estimate of 0.866); (iii) test-retest reliability was excellent with an intra-class correlation coefficient of 0.90; and (iv) floor and ceiling effects: six patients scored a maximum total ObsQoR-10 score. Conclusions The ObsQoR-10-Spanish patient-reported outcome measure is valid, reliable, and clinically feasible, and should be considered for use in Spanish-speaking women to assess quality of inpatient postpartum recovery.

Abstract
BACKGROUND Neuraxial analgesia provides effective pain relief during labor. However, it is unclear whether neuraxial analgesia prevalence differs across U.S. hospitals. The aim of this study was to assess hospital variation in neuraxial analgesia prevalence in California. METHODS A retrospective cross-sectional study analyzed birthing patients who underwent labor in 200 California hospitals from 2016 to 2020. The primary exposure was the delivery hospital. The outcomes were hospital neuraxial analgesia prevalence and between-hospital variability, before and after adjustment for patient and hospital factors. Median odds ratio and intraclass correlation coefficients quantified between-hospital variability. The median odds ratio estimated the odds of a patient receiving neuraxial analgesia when moving between hospitals. The intraclass correlation coefficients quantified the proportion of the total variance in neuraxial analgesia use due to variation between hospitals. RESULTS Among 1,510,750 patients who underwent labor, 1,040,483 (68.9%) received neuraxial analgesia. Both unadjusted and adjusted hospital prevalence exhibited a skewed distribution characterized by a long left tail. The unadjusted and adjusted prevalences were 5.4% and 6.0% at the 1st percentile, 21.0% and 21.2% at the 5th percentile, 70.6% and 70.7% at the 50th percentile, 75.8% and 76.6% at the 95th percentile, and 75.9% and 78.6% at the 99th percentile, respectively. The adjusted median odds ratio (2.3; 95% CI, 2.1 to 2.5) indicated substantially increased odds of a patient receiving neuraxial analgesia if they moved from a hospital with a lower odds of neuraxial analgesia to one with higher odds. The hospital explained only a moderate portion of the overall variability in neuraxial analgesia (intraclass correlation coefficient, 19.1%; 95% CI, 18.8 to 20.5%). CONCLUSIONS A long left tail in the distribution and wide variation exist in the neuraxial analgesia prevalence across California hospitals that is not explained by patient and hospital factors. Addressing the low prevalence among hospitals in the left tail requires exploration of the interplay between patient preferences, staffing availability, and care providers' attitudes toward neuraxial analgesia.

Abstract
BACKGROUND Psychological maltreatment by teachers and peer victimization are significant public health issues among youth. However, few studies have verified transactional associations between psychological maltreatment by teachers and peer victimization at the within-person level and the mediating roles of depression and aggression have yet to be fully evaluated. OBJECTIVE This study examined the transactional associations between psychological maltreatment by teachers and peer victimization from middle childhood to early adolescence, separating within- and between-person variation. The study also examined whether youth's depression and aggression mediated the associations. PARTICIPANTS AND SETTING A total of 4945 Chinese youth (Mage = 9.92 years, SD = 0.73 53 % boys) completed a packet of measures on five occasions at 6-month intervals from May of 2017 to May of 2019. METHODS Random Intercept Cross-Lagged Panel Models (RI-CLPMs) were used to distinguish between- and within-person effects. RESULTS The results indicated that: (a) Psychological maltreatment by teachers predicted peer victimization, and vice versa; (b) Depression (but not aggression) mediated the associations from peer victimization to psychological maltreatment by teachers. CONCLUSIONS The findings supported bidirectional spillover effects between adverse teacher-student and peer interactions and demonstrated at the within-person level that such effects were transmitted indirectly via youth's depression.

Abstract
BACKGROUND Neuraxial anesthesia with reactivation of a labor epidural catheter is commonly utilized for postpartum tubal ligations (PPTL), although the optimal anesthetic approach is unknown. We assessed institutional anesthesia practices for PPTL, and evaluated the failure rates of reactivation of labor epidural catheters, de novo spinal anesthesia, and spinal anesthesia after failed blocks. METHODS We conducted a single-center retrospective cohort analysis of 300 consecutive patients who underwent a PPTL and 100 having spinal anesthesia for cesarean delivery. Anesthetic management data (existing labor epidural catheter reactivation, de novo spinal anesthesia or general anesthesia) were collected from electronic medical records. Anesthetic block failure rates were determined for each anesthetic technique. RESULTS The failure rate was 15% for de novo spinal anesthesia and 23% after failed reactivation of a labor epidural catheter or spinal anesthesia. The epidural catheter reactivation failure rate was 35%. The failure rate of spinal anesthesia for cesarean delivery was 4%. Drug dosage, epidural catheter use in labor, time since epidural catheter placement or delivery, labor neuraxial technique (combined spinal-epidural, epidural), supplemental top-up doses during labor, and anesthesiologist experience did not predict neuraxial anesthesia failures. CONCLUSIONS Our analysis revealed an unexpectedly high neuraxial anesthesia failure rate even when de novo spinal anesthesia was used for PPTL. The results are consistent with other institutions' recent findings, and are higher than spinal anesthesia failure rates associated with cesarean delivery. Further studies are required to determine optimal anesthesia dosing strategies, and to understand the mechanisms behind high neuraxial anesthesia failures for PPTL.

Abstract
Disparities relating to postpartum recovery outcomes in different socio-economic and racial ethnic groups are underexplored. We conducted a planned analysis of a large prospective caesarean delivery cohort to explore the relationship between ethnicity, socio-economic status and postpartum recovery. Eligible patients were enrolled and baseline demographic, obstetric and medical history data were collected 18 h and 30 h following delivery. Patients completed postpartum quality of life and recovery measures in person on day 1 (EuroQoL EQ-5D-5L, including global health visual analogue scale; Obstetric Quality of Recovery-10 item score; and pain scores) and by telephone between day 28 and day 32 postpartum (EQ-5D-5L and pain scores). Socio-economic group was determined according to the Index of Multiple Deprivation quintile of each patient's usual place of residence. Data from 1000 patients who underwent caesarean delivery were included. There were more patients of Asian, Black and mixed ethnicity in the more deprived quintiles. Patients of White ethnicities had shorter postpartum duration of hospital stay compared with patients of Asian and Black ethnicities (35 (28-56 [18-513]) h vs. 44 (31-71 [19-465]) h vs. 49 (33-75 [23-189]) h, respectively. In adjusted models at day 30, patients of Asian ethnicity had a significantly greater risk of moderate to severe pain (numerical rating scale ≥ 4) at rest and on movement (odds ratio (95%CI) 2.42 (1.24-4.74) and 2.32 (1.40-3.87)), respectively). There were no differences in readmission rates or incidence of complications between groups. Patients from White ethnic backgrounds experience shorter postpartum duration of stay compared with patients from Asian and Black ethnic groups. Ethnic background impacts pain scores and recovery at day 1 postpartum and following hospital discharge, even after adjusting for socio-economic group. Further work is required to understand the underlying factors driving differences in pain and recovery and to develop strategies to reduce disparities in obstetric patients.

Abstract
Arsenic (As) contamination in soil poses a potential threat to human health via crop uptake. As-hyperaccumulator Pteris vittata serves as a model plant to study As uptake and associated mechanisms. This study focuses on a novel P/AsV transport system mediated by low-affinity phosphate transporter-B 1 family (PTB1) in P. vittata. Here, we identified two plasma-membrane-localized PTB1 genes, PvPTB1;1/1;2, in vascular plants for the first time, which were 4.4-40-fold greater in expression in P. vittata than in other Pteris ferns. Functional complementation of a yeast P-uptake mutant and enhanced P accumulation in transgenic Arabidopsis thaliana confirmed their role in P uptake. Moreover, the expression of PvPTB1;1/1;2 facilitated the transport and accumulation of As in both yeast and A. thaliana shoots, demonstrating a comparable AsV uptake capacity. Microdissection-qPCR analysis and single-cell transcriptome analysis collectively suggest that PvPTB1;1/1;2 are specifically expressed in the epidermal cells of P. vittata roots. PTB1 may play a pivotal role in efficient P recycling during phytate secretion and hydrolysis in P. vittata roots. In summary, the dual P transport mechanisms consisting of high-affinity Pht1 and low-affinity PTB1 may have contributed to the efficient P/As uptake in P. vittata, thereby contributing to efficient phytoremediation for As-contaminated soils.

Abstract
A rheo-microscopy in situ synchronous measurement system was utilized to investigate the dynamic behavior of water droplets in W/O waxy crude oil emulsions subjected to dynamic cooling conditions, the microstructural evolution of water droplets aggregates can be categorized into three stages based on the various forms of wax crystals. The results show that under the joint action of wax crystals and water droplets, the water droplets aggregation trend and complexity in the system are negatively correlated with the changes of temperature and shear rate, and the water droplets movement behavior is positively correlated with the changes of temperature and shear rate. As the temperature decreases, the minimum edge distance of water droplets decreases by a maximum of 32.1%, the specific surface area (SA) decreases by a maximum of 12.0%, and the fractal dimension increases by a maximum of 11.7%. As the shear rate increases, the minimum edge distance of water droplets increases by up to 27.9%, the specific surface area (SA) increases by up to 10.1%, and the fractal dimension decreases by up to 8.5%. Additionally, an analysis is conducted on the collision aggregation behavior of water droplets in shear flow field based on population balance theory.

Abstract
Wound healing is an intricate and fine regulatory process. In diabetic patients, advanced glycation end products (AGEs), excessive reactive oxygen species (ROS), biofilm formation, persistent inflammation, and angiogenesis regression contribute to delayed wound healing. Epigenetics, the fast-moving science in the 21st century, has been up to date and associated with diabetic wound repair. In this review, we go over the functions of epigenetics in diabetic wound repair in retrospect, covering transcriptional and posttranscriptional regulation. Among these, we found that histone modification is widely involved in inflammation and angiogenesis by affecting macrophages and endothelial cells. DNA methylation is involved in factors regulation in wound repair but also affects the differentiation phenotype of cells in hyperglycemia. In addition, noncodingRNA regulation and RNA modification in diabetic wound repair were also generalized. The future prospects for epigenetic applications are discussed in the end. In conclusion, the study suggests that epigenetics is an integral regulatory mechanism in diabetic wound healing.

Abstract
The structural characteristics of plant communities in urban green spaces have a significant impact on their carbon sequestration function. In this study, comprehensive data were collected from 106 plant communities (each 20 m × 20 m) in Zhengzhou Green Expo Park. We assessed aboveground and soil carbon storage, alongside maintenance carbon emissions, to quantify carbon dynamics. Our primary objective was to establish a statistical model that correlates the structural attributes of plant communities with their total annual carbon sequestration. This model aims to provide a quantitative framework for optimizing community structures to maximize carbon sequestration in urban green spaces. The results showed that density and coverage were significantly and positively correlated with aboveground and soil carbon stocks. Density and mean height were significantly and positively correlated with maintenance carbon emissions. Density played a key structural role in regulating the total carbon sequestration of the plant communities, being 27.24 times more effective than coverage. The total annual carbon sequestration of the plant community reached an optimal value of 327.67 kg CO2-eq/y-1 at a density and cover of 0.15 and 1, respectively. This study provides valuable data for increasing the carbon sink ability of urban green spaces through plant structure regulation and supporting low-carbon development strategies in urban management.

Abstract
Background The role of continuous wound infusion catheters as part of a multimodal analgesia strategy after Caesarean delivery is unclear. We introduced continuous wound infusion catheters to our multimodal analgesia regimen to evaluate the impact on analgesic outcomes after Caesarean delivery. Methods After institutional review board (IRB) approval, a 4-month practice change was instituted as a quality improvement initiative. In addition to multimodal analgesia, continuous wound infusion catheters for up to 3 days were offered on alternate weeks for all women undergoing Caesarean deliveries. The primary outcome was postoperative in-hospital opioid consumption. Secondary outcomes were static and dynamic pain scores at 24 and 72 h, time until first analgesic request, opioid-related side-effects, length of stay, satisfaction (0-100%), and continuous wound infusion catheter-related complications. Results All women scheduled for Caesarean delivery (n=139) in the 4-month period were included in the analysis, with 70 women receiving continuous wound infusion catheters, and 69 in the control group. Opioid consumption (continuous wound infusion catheter group 11.3 [7.5-61.9] mg morphine equivalents vs control group 30.0 [11.3-48.8] mg morphine equivalents), pain scores (except 24 h resting pain scores which were higher in the control group 2 [1-3] vs 1.5 [0-3] in the continous wound infusion catheters group; P=0.05), side-effects, length of stay, and complications were similar between groups. Satisfaction scores at 24 h were higher with continuous wound infusion catheters (100% [91-100%] vs 90% [86-100%]; P=0.003) with no differences at 72 h. One patient demonstrated symptoms of systemic local anaesthetic toxicity which resolved without significant harm. Conclusions The addition of continuous wound infusion catheters to a multimodal analgesia regimen for post-Caesarean delivery pain management demonstrated minimal clinically significant analgesic benefits. Future studies are needed to explore the use of continuous wound infusion catheters in populations that may benefit most from this intervention.

Abstract
Cadmium (Cd) contamination in soils is of great concern for plant growth and human health. Willow (Salix spp.) is a promising phytoextractor because of its high biomass production. However, as a non-hyperaccumulator, willow has a low competitive ability in extraction of Cd. Thus, improving Cd concentrations in developing tissues is one of the primary tasks. Here, our study uncovers a novel SsIRT9 gene from Sailx suchowensis which manipulates plant Cd accumulation. SsIRT9 was more highly expressed in willow roots than other SsIRT genes. As a plasma membrane-localized protein, when expressed in yeast, SsIRT9 retarded cell growth more severely than other SsIRT proteins in the presence of Cd. Furthermore, SsIRT9 was cloned and expressed in tobacco and SsIRT9 did not affect plant growth. In hydroponic experiments, SsIRT9 lines displayed higher Cd in the shoots than the wild type. When grown in Cd-contaminated soils, Cd levels in transgenic tobacco increased by 152-364% in roots and by 135-444% in shoots, demonstrating significant superiority in Cd accumulation over other functional IRT/ZIP transporters. Moreover, expressing SsIRT9 in tobacco altered metal homeostasis, especially manganese and zinc. Taken together, we envision that SsIRT9 expression in plants is a promising strategy for upgrading extraction of Cd from soils.

Abstract
Sarcophaga (Liosarcophaga) angarosinica (Rohdendorf, 1937) (Diptera: Sarcophagidae) is a species of both medical and ecological significance. In this study, the complete mitochondrial genome (mitogenome) of S. angarosinica was sequenced and characterized. The mitogenome has a total length of 15,215 bp, including 13 protein-coding genes, two ribosomal RNAs, 22 transfer RNAs, and an adenine and thymine-rich region. This mitogenome comprises 39.5% adenine, 9.4% guanine, 14.4% cytosine, and 36.8% thymine. Phylogenetic analysis revealed that S. angarosinica is closely related to Sarcophaga similis. This study enriches the genetic data on S. angarosinica and will contribute to establishing the phylogenetic relationships among flesh flies.

Abstract
Our aim in this study was to translate and psychometrically evaluate a Chinese version of the Behavioral Regulation in Sport Questionnaire (BRSQ). Participants were Chinese collegiate athletes (N = 361) who were competitive in their respective sports. We examined the construct validity of the Chinese BRSQ using alternative structural equation models and evaluated convergent validity, factor score reliability, and measurement invariance of the optimal model. Due to insufficient score reliability for some subscales, our initial Chinese BRSQ was deemed problematic. A modified version of the questionnaire with a four-factor structure (amotivation, external regulation, introjected regulation, and autonomous motivation) demonstrated excellent construct validity, convergent validity, and score reliability. There was measurement invariance across athlete level and sex. This tool provides a valuable resource for practitioners and sport psychology researchers for assessing sport motivation among competitive university athletes in China.

Abstract
Introduction: Elderly patients are more prone to develop acute kidney injury during infections and polymyxin B (PMB)-associated nephrotoxicity than young patients. The differential response to PMB between the elderly and young critically ill patients is unknown. We aimed to assess PMB exposure in elderly patients compared with young critically ill patients, and to determine the covariates of PMB pharmacokinetics in critically ill patients. Methods: Seventeen elderly patients (age ≥ 65 years) and six young critically ill patients (age < 65 years) were enrolled. Six to eight blood samples were collected during the 12 h intervals after at least six doses of intravenous PMB in each patient. PMB plasma concentrations were quantified by high-performance liquid chromatography-tandem mass spectrometry. The primary outcome was PMB exposure as assessed by the area under the concentration-time curve over 24 h at steady state (AUCss, 0-24 h). Results and Discussion: The elderly group had lower total body weight (TBW) and higher Charlson comorbidity scores than young group. Neither AUCss, 0-24 h nor normalized AUCss, 0-24 h (adjusting AUC for the daily dose in mg/kg of TBW) was significantly different between the elderly group and young group. The half-life time was longer in the elderly patients than in young patients (11.21 vs 6.56 h respectively, p = 0.003). Age and TBW were the covariates of half-life time (r = 0.415, p = 0.049 and r = -0.489, p = 0.018, respectively). TBW was the covariate of clearance (r = 0.527, p = 0.010) and AUCss, 0-24 h (r = -0.414, p = 0.049). Patients with AUCss, 0-24 h ≥ 100 mg·h/L had higher baseline serum creatinine levels and lower TBW than patients with AUCss, 0-24 h < 50 mg·h/L or patients with AUCss, 0-24 h 50-100 mg·h/L. The PMB exposures were comparable in elderly and young critically ill patients. High baseline serum creatinine levels and low TBW was associated with PMB overdose. Trial registration: ChiCTR2300073896 retrospectively registered on 25 July 2023.

Abstract
Background: Chinese patent medicines (CMPs) have curative effectiveness in preventing coronary restenosis. However, the relative efficacy between different CPMs has not been sufficiently investigated. Methods: Randomized clinical trials were searched from electronic databases including PubMed, Web of Science, Cochrane Library, Embase, CNKI, VIP, WanFang, SinoMed, Chinese Clinical Trial Registry, and ClinicalTrials.gov. Bayesian network meta-analysis was performed to analyze CPMs' efficacy in preventing angiographic restenosis, recurrence angina, acute myocardial infarction, and target lesion revascularization after percutaneous coronary intervention. Results: This network meta-analysis included 47 trials with 5,077 patients evaluating 11 interventions. Regarding angiographic restenosis, the efficacy of CPMs (except Xuezhikang capsule) combined with standard treatment (Std) was superior to Std alone, and Guanxin Shutong capsule plus Std reduced the risk of angiographic restenosis by 76% (relative risk 0.24, 95% confidence interval 0.11-0.45, and very low to moderate certainty of evidence), most likely the best intervention. Fufang Danshen dripping pill combined with Std showed superiority over other interventions for relieving recurrence angina, which can reduce the risk by 83% (RR 0.17, 95% CI 0.04-0.51, very low to moderate certainty of evidence) compared to Std alone. In acute myocardial infarction after percutaneous coronary intervention, compared with Std alone, Danhong injection plus Std displayed a significant effect (RR 0.11, 95% CI 0.00-0.69, very low to moderate certainty of evidence) and was the best treatment probably. Chuanxiongqin tablet plus Std was the most effective treatment for reducing target lesion revascularization by 90% (RR 0.10, 95% CI 0.00-0.60, very low to moderate certainty of evidence) compared with Std alone. Conclusion: The results indicated that CPMs combined with Std reduced the risk of coronary restenosis after percutaneous coronary intervention. However, the results should be interpreted cautiously due to significant data limitations.

Abstract
Intercropping heavy metal hyperaccumulators and low-accumulating cultivars is a promising strategy for remediating contaminated soils without impeding agricultural production. A field plot experiment was conducted to explore the effects of intercropping maize with Brassica juncea L. on the rhizosphere microecological properties, plant growth and cadmium (Cd) accumulation. The results showed that the Cd bioaccumulation amount per unit area (BCAarea) of the intercropping system was 12.9% lower than that of the Brassica juncea L. monoculture but 87.5% higher than that of the maize monoculture. The grain yield of maize was increased by 10.5% through intercropping, and the land equivalent ratio (LER) was greater than 1. Soil available Cd in intercropped maize was 13.4% lower than that in monoculture maize but was 12.7% higher in intercropped Brassica juncea L. than in monoculture Brassica juncea L. Intercropping significantly increased the contents of malic acid and citric acid in the rhizospheres of maize and Brassica juncea L. The dominant microorganisms were similar in all studied soils but were different in relative abundance between the intercropping and monoculture treatments. These findings suggest that intercropping maize with Brassica juncea L. could be a promising approach for phytoremediation without reducing crop yield in Cd-contaminated soil.

Abstract
Objective To investigate the effect of micro-implant anchorage combined with a clear aligner on the efficiency of mandibular molar distalization and the protection of anterior teeth anchorage, provide reference for clinical scheme design. Methods This is a prospective study. Seventeen patients who were treated in the Orthodontics Department of the Hospital of Stomatology affiliated to Fujian Medical University from 2019 to 2021 and used Invisalign clear aligners to move mandibular molars distally were included and divided into two groups according to anchorage types: Group-A and Group-B. Group-A (ten cases) were treated without micro-implant anchorage, while Group-B (seven cases) were treated with micro-implant anchorage nails for enhanced anchorage. The effect of micro-implant anchorage on crown and root distal movement of mandibular molars and the difference in three-dimensional movement between mandibular molars and mandibular central incisors were analyzed. Results The crown distalization efficiency of mandibular first and second molars in Group-B was 68.66% and 71.02%, respectively, which were higher than those in Group-A(p<0.05). The mandibular central incisors in Group-A showed labial displacement and a small amount of elongation, while those in Group-B showed less anchorage loss(p<0.05). In Group-A, the crown was tilted in the distal direction and moved in the buccal direction during mandibular molar distalization(p<0.05). While in Group-B, the crown was tilted in the distal directio (p<0.05) and the mandibular second molar was depressed(p<0.05). Conclusion In the process of mandibular molar distalization assisted by micro-implant anchorage combined with a clear aligner, better protects the anchorage of the mandibular central incisor and improves the efficiency of the molar crown distalization.

Abstract
BACKGROUND Anesthesiology experts advocate for formal education in maternal critical care, including the use of focused cardiac ultrasound (FCU) in high-acuity obstetric units. While benefits and feasibility of FCU performed by experts have been well documented, little evidence exists on the feasibility of FCU acquired by examiners with limited experience. The primary aim of this study was to assess how often echocardiographic images of sufficient quality to guide clinical decision-making were attained by trainees with limited experience performing FCU in term parturients undergoing cesarean delivery (CD). METHODS In this prospective cohort study, healthy term parturients (American Society of Anesthesiologists [ASA] ≤ 3, ≥37 weeks of gestation) with singleton pregnancy, body mass index (BMI) <40 kg/m2, and no history of congenital and acquired cardiac disease undergoing scheduled, elective CD were recruited by a trainee. After undergoing standardized training, including an 8-hour online E-learning module, a 1-day hands-on FCU course, and 20 to 30 supervised scans until the trainee was assessed competent in image acquisition, 8 trainees with limited FCU experience performed apical 4-chamber (A4CH), parasternal long-axis (PLAX), and short-axis (PSAX) view preoperatively after spinal anesthesia (SPA) and intraoperatively after neonatal delivery (ND). Obtained FCU images were graded 1 to 5 by 2 blinded instructors (1 = no image to 5 = perfect image obtainable; ≥3 defined as image quality sufficient for clinical decision-making). RESULTS Following the screening of 95 women, 8 trainees with limited FCU experience each performed a median of 5 [3-8] FCUs in a total of 64 women. Images of sufficient quality were obtainable in 61 (95.3 %) and 57 (89.1 %) of women after SPA and ND, respectively. FCU images of perfect image quality were obtainable in 9 (14.1 %) and 7 (10.9 %) women preoperatively after SPA and intraoperatively after ND, respectively. A PLAX, PSAX, and A4CH view with grade ≥3 was obtained in 53 (82.8 %), 58 (90.6 %) and 40 (62.5 %) of women preoperatively after SPA and in 50 (78.1 %), 49 (76.6 %), and 29 (45.3 %) of women intraoperatively after ND. Left ventricular function could be assessed in 39 of 40 women (97.5 %) preoperatively after SPA and 39 of 40 (97.5%) intraoperatively after ND. Right ventricular function could be assessed in 31 of 40 (77.5 %) after SPA and in 23 of 40 (59%) after ND. We observed a difference in image grading between different trainees in the AP4CH-view (P = .0001). No difference in image grading was found between preoperative and intraoperative FCUs. CONCLUSIONS FCU is feasible in the parturient undergoing CD and images of sufficient quality for clinical decision-making were obtained by trainees with limited experience in almost all parturients. Image acquisition and quality in the A4CH view may be impacted by the individual trainee performing the FCU.

Abstract
INTRODUCTION There is a dearth of comprehensive studies on the association between serum electrolyte and adverse short-term prognosis of Chinese patients with acute decompensated heart failure (ADHF). PATIENTS AND METHODS A total of 5166 patients with ADHF were divided into four serum electrolyte-related study populations (potassium (n = 5145), sodium (n = 5135), chloride (n = 4966), serum total calcium (STC) (n = 4143)) under corresponding exclusions. Different logistic regression models were utilized to gauge the association between these electrolytes or the number of electrolyte abnormalities and the risk of a composite of all-cause mortality or 30-day heart failure (HF) readmission. RESULTS In multivariable adjusted analysis, patients with potassium below 3.5 mmol/L (odds ratios (ORs) 1.45; 95% confidence interval (CI):1.07-1.95), 4.01-4.50 mmol/L (OR: 1.29, CI: 1.02-1.62), 4.51-5.00 mmol/L (OR: 1.43, CI: 1.08-1.90) and above 5.00 mmol/L (OR: 1.74, CI: 1.21-2.51) had an increased risk of outcome when compared with potassium at 3.50-4.00 mmol/L. Sodium levels were inversely related to the risk of a composite outcome (<130 mmol/L: OR: 2.73 (95% CI, 1.81-4.12); 130-134 mmol/L: OR, 1.97 (CI, 1.45-2.68); 135-140 mmol/L: OR, 1.45 (CI, 1.17-1.81); p for trend < 0.001) in comparison with sodium at 141-145 mmol/L. Chloride < 95 mmol/L corresponded to a higher risk of a composite outcome with an OR of 1.65 (95% CI, 1.16-2.37) in contrast to chloride levels at 101-105 mmol/L. In addition, the adjusted ORs (95% CI) for a composite outcome comparing the STC < 2.00 and 2.00-2.24 vs. 2.25-2.58 mmol/L were 0.98 (0.69-1.43) and 1.13 (0.89-1.44), respectively. Besides that, the number of electrolyte abnormalities was positively related to the risk of a composite outcome (N = 1, OR 1.40, 95% CI: 1.13-1.73; N = 2, OR 2.51, 95% CI: 1.85-3.42; N = 3, OR 2.47, 95% CI: 1.45-4.19; p for trend < 0.001) in comparison with N = 0. CONCLUSIONS A deviation of potassium levels from 3.50 to 4.00 mmol/L, lower sodium levels and hypochloremia were associated with poorer short-term prognosis of ADHF. Furthermore, the number of electrolyte abnormalities positively correlated with adverse short-term prognosis of patients with ADHF. Key MessagesADHF patients with baseline serum potassium at first half part of normal range (3.50-4.00 mmol/L) may herald the lowest risk of recent cardiovascular events.Serum sodium and chloride levels exhibit discrepancies in terms of risk of short-term adverse events of ADHF patients.The number of electrolyte abnormalities is a significant predictor of poor short-term prognosis in patients with ADHF.

Abstract
OBJECTIVE To describe the prevalence and predictors of postpartum sleep disorders. DESIGN A retrospective cohort study. SETTING Postpartum. POPULATION Commercially insured women delivering in California (USA) between 2011 and 2014. METHODS Using the Optum Clinformatics Datamart Database. MAIN OUTCOME MEASURES Prevalence of a postpartum sleep disorder diagnosis with and without a depression diagnosis up to 12 months following hospital discharge for inpatient delivery. We also identified predictors of a postpartum sleep disorder diagnosis using multivariable logistic regression. RESULTS We identified 3535 (1.9%) women with a postpartum sleep disorder diagnosis. The prevalence of sleep disorder diagnoses was insomnia (1.3%), sleep apnea (0.25%), and other sleep disorder (0.25%). The odds of a postpartum sleep disorder were highest among women with a history of drug abuse (adjusted odds ratio (aOR): 2.70, 95% confidence interval (CI): 1.79-4.09); a stillbirth delivery (aOR: 2.15, 95% CI: 1.53-3.01); and chronic hypertension (aOR: 1.82; 95% CI: 1.57-2.11). A comorbid diagnosis of a postpartum sleep disorder and depression occurred in 1182 women (0.6%). These women accounted for 33.4% of all women with a postpartum sleep disorder. The strongest predictors of a comorbid diagnosis were a history of drug abuse (aOR: 4.13; 95% CI: 2.37-7.21) and a stillbirth delivery (aOR: 2.93; 95% CI: 1.74-4.92). CONCLUSIONS Postpartum sleep disorders are underdiagnosed conditions, with only 2% of postpartum women in this cohort receiving a sleep diagnosis using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes. Insomnia was the most common disorder and one-third of women diagnosed with a postpartum sleep disorder had a co-morbid diagnosis of depression. Future studies are needed to improve the screening and diagnostic accuracy of postpartum sleep disorders.

Abstract
STUDY OBJECTIVE To explore the relationship between Obstetric Quality of Recovery survey (ObsQoR-10-Heb) and Edinburgh postnatal depression scale (EPDS) measured 6 weeks after delivery, adjusted for potential confounding factors. DESIGN Prospective, longitudinal cohort study. SETTING Large postpartum department, 13,000 annual deliveries, quaternary medical center in Israel. PATIENTS Women ≥18 years old, gestational age ≥ 37 weeks after term delivery (spontaneous vaginal, operative vaginal, planned, and unplanned cesarean delivery), with non-anomalous neonates not requiring special support after delivery or at the time of recruitment. Written informed consent was provided. Women unable to read or understand Hebrew were excluded. INTERVENTIONS No interventions were done. MEASUREMENTS We investigated the relationship between inpatient postpartum recovery and positive postpartum depression (PPD) screening at 6 weeks postpartum. Enrolled women completed the validated Hebrew version of ObsQoR-10 survey (ObsQoR-10-Heb; scored between 0 and 100 with 0 and 100 representing worst and best possible recovery) from 24 to 48 h after delivery, and the Edinburgh Postnatal Depression Scale (EPDS) at 6- and 12 weeks postpartum. We assessed the univariate association between ObsQoR-10-Heb; patient factors; obstetric factors; and positive PPD screening at 6 weeks postpartum. Potential confounders were adjusted in a multiple logistic regression model. MAIN RESULTS Inpatient ObsQoR-10-Heb has been completed by 325 postpartum women; 270 (83.1%) and 253 (77.9%) completed the 6- and 12 weeks EPDS respectively. Lower ObsQoR-10-Heb (aOR 0.95 (95% CI 0.92, 0.98); p = 0.001); depression or anxiety before delivery (aOR 4.53 (95% CI 1.88, 10.90); p = 0.001); and hospital readmission (aOR 9.08 (95% CI 1.23, 67.14); p = 0.031) were associated with positive screening for postpartum depression at 6 weeks. CONCLUSIONS Our study demonstrates that worse inpatient postpartum recovery is an independent risk factor for positive PPD screening at 6 weeks postpartum. Other risk factors found in our study were maternal hospital readmission and a previous history of anxiety or depression.

Abstract
Objectives Suspected coarctation of the aorta (CoA) is a common fetal echocardiographic presentation. However, the prenatal findings did not indicate a satisfied accuracy in determining the truly CoA after birth, which made the prenatal diagnosis of CoA still as a critical challenge with high false positive rate. Thus, this research is aimed to distinguish the potential prenatal parameters influencing the fetal echocardiographic images and enhance the true positive diagnostic rate of CoA fetuses which require early clinical intervention in postnatal life. Methods A retrospective study had been designed and fetuses with suspected with CoA had been included from Jan 2016 to Dec 2021 in our center. The fetal echocardiography and related clinical information had been collected. And the postnatal diagnosis had been reached by echocardiography or CTA. Then, all the parameters had been analyzed by univariate analysis, and a multivariate logistic regression analysis was further involved to determine the independent parameters influencing the accuracy of diagnosis CoA fetuses. Moreover, such results had been validated by nomogram analysis and ROC curve. Results Among the included 44 liveborn infants who presented suspected CoA in fetal cardiac screening, 18 cases had been proved to be CoA postnatally (Group P). The true positive rate for this study was 40.9% (18/44). The abnormal atrial hemodynamic status (AAHs) and the gestational week of delivery (GWoD) were associated with the postnatal CoA confirmation among prenatal suspected fetuses. The ROC curve of predicting probability of the mode combined with two independent factors of absence of AAH and GWoD (AUC = 0.880, 95% CI 0.763-0.997) presented a satisfied efficacy in distinguishing postnatal positive CoA diagnosis. The nomogram plot had been be utilized in CoA prediction (model likelihood ratio test, p < 0.0001). Conclusions AAH and GWoD had been identified as independent factors of predictive accuracy in detecting postnatal CoA among prenatal suspected fetuses. The prediction mode based on nomogram scores could be used to predict the risk of occurring CoA fetuses.

Abstract
Objective To evaluate the effects of periodontal initial therapy combined with orthodontic treatment on anterior tooth function and inflammatory factors in gingival crevicular fluid in patients with periodontal disease induced anterior tooth displacement. Methods This was a clinical comparative study. A total of 140 patients with anterior teeth displacement caused by periodontal disease in Fujian University of Traditional Chinese Medicine from May 2020 to May 2022 were selected and randomly divided into two groups. Patients in the control group received periodontal initial therapy, and those in the study group were provided with orthodontic treatment on the basis of initial therapy. Further comparative analysis was performed focusing on the clinical effects of the two groups, the changes of probing depth, anterior overjet degree, oral function and inflammatory factors in gingival crevicular fluid before and after treatment. Results The efficacy of the study group was significantly higher than that of the control group(p=0.00). After treatment, the probing depth, the anterior overjet degree and the rate of bleeding on probing in the study group were significantly lower than those in the control group(P=0.00). Furthermore, the proportion of tooth mobility degrees I, II and III in the study group was significantly lower than that in the control group after treatment(P<0.05). The levels of post-treatment inflammatory factors in the study group were significantly lower than those in the control group(p=0.00). Conclusion Periodontal initial therapy combined with orthodontic treatment has a significant effect on anterior teeth displacement caused by periodontal disease, which deserves promotion clinically.

Abstract
AIMS Dasatinib, a second-generation tyrosine kinase inhibitor of BCR-ABL 1, used for first-line treatment of Philadelphia chromosome-positive chronic myeloid leukemia (CML), exhibits high pharmacokinetic (PK) variability. However, its PK data in Chinese patients with CML remains rarely reported to date. Thus, we developed a population pharmacokinetic (PPK) model of dasatinib in Chinese patients and identified the covariate that could explain the individual variability of PK for optimal individual administration. METHODS PPK modeling for dasatinib was performed based on 754 plasma concentrations obtained from 140 CML patients and analysis of various genetic and physicochemical parameters. Modeling was performed with nonlinear mixed-effects (NLME) using Phoenix NLME. The finally developed model was evaluated using internal and external validation. Monte Carlo simulations were used to predict drug exposures at a steady state for various dosages. RESULTS The PK of dasatinib were well described by a two-compartment with a log-additive residual error model. Patients in the current study had a relatively low estimate of CL/F (126 L/h). A significant association was found between the covariate of age and CL/F of dasatinib, which was incorporated into the final model. None of the genetic factors was confirmed as a significant covariate for dasatinib. The results of external validation with 140 samples from 36 patients were acceptable. Simulation results showed significantly higher exposures in elderly patients. CONCLUSIONS This study's findings suggested that low-dose dasatinib would be better suited for Chinese patients, and the dosage can be appropriately reduced according to the increase of age, especially for the elderly.

Abstract
INTRODUCTION Physiologically based pharmacokinetics (PBPK) models are increasingly used in the drug research and development, especially in anti-cancer drugs. Between 2001 and 2020, a total of 89 small-molecule targeted antitumor drugs were approved in China and the United States, some of which already included PBPK modeling in their application or approval packages. This article intended to review the prevalence and application of PBPK model in these drugs. METHOD Article search was performed in the PubMed to collect English research articles on small-molecule targeted anti-cancer drugs using PBPK modeling. The selected articles were classified into nine categorizes according to the application areas and further analyzed. RESULT From 2001 to 2020, more than 60% of small-molecule targeted anti-cancer drugs (54/89) were studied using PBPK model with a wide range of application. Ninety research articles were included, of which 48 involved enzyme-mediated drug-drug interaction (DDI). Of these retrieved articles, Simcyp, GastroPlus, and PK-Sim were the most widely model building platforms, which account for 63.8%, 15.2%, and 8.6%, respectively. CONCLUSION PBPK modeling is commonly and widely used to research small-molecule targeted anti-cancer drugs.

Abstract
Interleukin-12 (IL-12) is involved in the occurrence and development of many diseases, such as preeclampsia, intrauterine growth restriction, preterm labor, and recurrent pregnancy losses. This study aimed to determine whether a high serum level of IL-12 was associated with adverse in vitro fertilization (IVF) outcomes. Included infertile women with high serum IL-12 levels who underwent IVF cycles and infertile controls with pure tubal etiology. The impact of serum IL-12 on baseline and clinical characteristics, immune-related indicators, IVF laboratory, and pregnancy outcomes were compared. In addition, the correlation of follicular fluid IL-12 and serum IL-12 level and the role of IL-12 in apoptosis of granulosa cells (GCs) was investigated. Women with high serum IL-12 levels had lower numbers of retrieved oocytes, embryos, perfect and available embryos, lower rates of perfect and available embryos, and blastocyst formation. Additionally, significantly higher levels of serum Th1, Th2, and Th17-related cytokines were observed in women with high serum IL-12 levels than in the controls. Meanwhile, the follicular fluid IL-12 levels were positively correlated with serum IL-12 levels, and IL-12 promoted apoptosis of GCs in vitro. We concluded that women with serum high IL-12 levels may have adverse IVF outcomes, partly by promoting apoptosis of GCs. Therefore, early screening for cytokines, especially IL-12, and appropriate consultation for couples receiving IVF-ET should be considered. In addition, specific immune and inflammatory mechanisms associated with high serum IL-12 levels should be further explored.

Abstract
The motion behaviors, rheological properties, and mechanical properties of a wax crystal mesoscale force chain network of waxy crude oil during gelation were experimentally studied and simulated by rheo-optic in situ measurement and computational fluid dynamics-discrete element method (CFD-DEM) numerical simulation, respectively. The motion behavior characteristics of wax crystals and the changes in the average coordination number of wax crystal networks were obtained at different temperatures. The study investigates the rule of crude oil rheological deterioration, the increase of wax crystals, and the changes in wax crystal motion behaviors with decreasing temperature. The relationship between the structure of the mesoscale force chain of the wax crystal network and the motion behaviors of the wax crystal and its rheological properties was analyzed. The results show that the average motion velocity of wax crystals or aggregates decreases from 28.48 to 22.56 μm/s when the temperature decreases from wax appearance temperature (48 °C) to 25 °C. The rotation and rolling trend of wax crystals gradually flatten, and the average coordination number increases 4.39 times. The viscosity of waxy crude oil increases from 6.27 to 8369.7 mPa·s, and the average coordination number of wax crystals obtained by CFD-DEM also increases significantly, which confirms the experimental results. We also found that when the system tended to gelation, a complex and stable force chain network was formed between the wax crystals, with a force chain coverage of 87.93% and a significant increase in the pressure drop in the flow field, which is consistent with the variation pattern of the system viscosity. The micro-meso-dynamic behavior analysis of waxy crude oil combined with CFD-DEM coupling provides a new way to explore the rheological properties of waxy crude oil and the microscopic mechanism of its modification.

Abstract
BACKGROUND 1q21.1q21.2 microdeletions/microduplications are rare and incompletely penetrant genetic mutations, and only a few reports regarding their prenatal diagnosis are currently available. Here, we analyzed the ultrasonographic phenotypic characteristics of fetuses with these mutations to improve the understanding, diagnosis, and screening of these mutations during gestation. METHODS We retrospectively analyzed 8700 cases of pregnant women who underwent invasive prenatal screening by karyotyping and chromosomal microarray analysis (CMA) between November 2016 and November 2021. RESULTS CMA revealed copy number changes in the 1q21.1q21.2 region of eleven fetuses, of which five had microdeletions and six had microduplications. These eleven fetuses exhibited variable ultrasonographic phenotypes. Of the five fetuses with the microdeletion, one exhibited a right-dominant heart, permanent right umbilical vein, and mild tricuspid regurgitation, another showed thickened nuchal translucency, and the remaining three had normal ultrasound phenotypes. Two of the six cases with 1q21.1q21.2 microduplication had structural malformations; one of them had a bilateral subependymal cyst, neck mass, and enlarged cardiothoracic ratio, while the other had right ventricular hypoplasia. Of the remaining four cases, two exhibited nasal bone dysplasia, one showed measurement slower than that during menopause and mild tricuspid regurgitation, and another did not show any notable abnormality in ultrasound examination. Among the eleven cases of 1q21.1q21.2 microdeletion/microduplication, only the parents of two fetuses underwent pedigree verification. The parents of these two fetuses with 1q21.1q21.2 microdeletion syndrome chose to continue the pregnancy, and all aspects of postnatal follow-up were normal. The parents of the other nine fetuses refused pedigree verification; of these cases, four cases terminated, and five cases continued the pregnancies. The five continued pregnancies were followed up after birth; no abnormalities were found. CONCLUSIONS Fetuses with 1q21.1q21.2 microdeletion/microduplication show different ultrasound characteristics and may have congenital heart disease, thickened nuchal translucency, and nasal bone dysplasia or show no notable abnormalities in an ultrasound examination. Our study highlights that CMA as a powerful diagnostic tool for these diseases can provide an accurate genetic diagnosis, while improving prenatal diagnosis standards.

Abstract
Gluconeogenesis is closely related to the occurrence and development of type 2 diabetes mellitus (T2DM). Gentiopicroside (GPS) is the main active secoiridoid glycoside in Gentiana manshurica Kitagawa, which can improve chronic complications associated with diabetes and regulate glucose metabolism. However, the effects and potential mechanisms by which GPS affects T2DM understudied and poorly understood. In this study, we systematically explored the pharmacological effects of GPS on T2DM induced by a high-fat diet (HFD) and streptozotocin (STZ) as well as explored its related mechanisms. The results showed that GPS supplementation discernibly decreased blood glucose levels, food intake and water consumption, ameliorated glucose intolerance, abnormal pyruvate tolerance, insulin resistance and dyslipidemia. Furthermore, GPS discernibly ameliorated pathological morphological abnormalities of the liver and pancreas, reduced hepatic steatosis and maintain the balance between α-cells and β-cells in pancreas. Moreover, GPS significantly inhibited gluconeogenesis, as evidenced by the suppressed protein expression of phosphoenolpyruvate carboxykinase (PEPCK) and glucose 6-phosphatase (G6Pase) in the liver. Additionally, the results of Western blot analysis revealed that GPS increased p-PI3K, p-AKT, and p-FOXO1 expression levels, and decreased FOXO1 expression at protein level in the liver. Furthermore, the results of the immunostaining and Western blot analysis demonstrated that GPS supplementation increased the expression of zonula occludens-1 (ZO-1) and occludin in the ileum. Collectively, these results indicate that GPS may inhibit hepatic gluconeogenesis by regulating the PI3K/AKT/FOXO1 signaling pathway and maintain intestinal barrier integrity, and ultimately improve T2DM. Together, these findings indicate that GPS is a potential candidate drug for the prevention and treatment of T2DM, and the results of our study will provide experimental basis for further exploration of the possibility of GPS as a therapeutic agent for T2DM.

Abstract
Importance Dural-puncture epidural (DPE) and standard epidural are common modes of neuraxial labor analgesia. Little is known about conversion of DPE-initiated labor analgesia to surgical anesthesia for cesarean delivery. Objective To determine whether DPE provides a faster onset and better-quality block compared with the standard epidural technique for cesarean delivery. Design, Setting, and Participants This double-blind, randomized clinical trial was conducted between April 2019 and October 2022 at a tertiary care university hospital (University of Arkansas for Medical Sciences). Participants included women aged 18 years and older undergoing scheduled cesarean delivery with a singleton pregnancy. Interventions Participants were randomized to receive DPE or standard epidural in the labor and delivery room. A T10 sensory block was achieved and maintained using a low concentration of bupivacaine with fentanyl through the epidural catheter until the time of surgery. Epidural extension anesthesia was initiated in the operating room. Main Outcomes and Measures The primary outcome was the time taken from chloroprocaine administration to surgical anesthesia (T6 sensory block). The secondary outcome was the quality of epidural anesthesia, as defined by a composite of the following factors: (1) failure to achieve a T10 bilateral block preoperatively in the delivery room, (2) failure to achieve a surgical block at T6 within 15 minutes of chloroprocaine administration, (3) requirement for intraoperative analgesia, (4) repeat neuraxial procedure, and (5) conversion to general anesthesia. Results Among 140 women (mean [SD] age, 30.1 [5.2] years), 70 were randomized to the DPE group, and 70 were randomized to the standard epidural group. The DPE group had a faster onset time to surgical anesthesia compared with the standard epidural group (median [IQR], 422 [290-546] seconds vs 655 [437-926] seconds; median [IQR] difference, 233 [104-369] seconds). The composite rates of lower quality anesthesia were 15.7% (11 of 70 women) in the DPE group and 36.3% (24 of 66 women) in the standard epidural group (odds ratio, 0.33; 95% CI, 0.14-0.74; P = .007). Conclusions and Relevance Anesthesia initiated following a DPE technique resulted in faster onset and improved block quality during epidural extension compared with initiation with a standard epidural technique. Further studies are needed to confirm these findings in the setting of intrapartum cesarean delivery. Trial Registration ClinicalTrials.gov Identifier: NCT03915574.

Abstract
This study aimed to identify gender-specific co-developmental trajectories of internalizing and externalizing problems from middle childhood to early adolescence, along with key environmental and individual predictors among Chinese youth. A total of 1653 Chinese elementary school students (M age = 9.40; SD = 0.51; 54.57% boys) participated in assessments at six time points, using 6-month assessment intervals. Parallel process latent class growth modeling identified four trajectories for boys: Congruent-low (65.74%), moderate-decreasing internalizing and moderate-stable externalizing problems (18.40%), high increasing-internalizing and low-stable externalizing problems (8.20%), and high decreasing-internalizing and low-stable externalizing problems (7.65%). Three trajectories were identified for girls: Congruent-low (81.09%), moderate co-occurring (7.19%), and high increasing-internalizing and low-stable externalizing problems (11.72%). Multivariate logistic regression analyses revealed that peer victimization served as an environmental risk predictor for the adverse co-developmental trajectories of internalizing and externalizing problems for boys and girls. High sensation-seeking and low self-control served as individual risk variables predicting the trajectories of high increasing-internalizing and low-stable externalizing problems, and low self-control also predicted the trajectories of high decreasing-internalizing and low-stable externalizing problems for boys. The findings highlight the importance of gender differences in understanding the progression of internalizing and externalizing problems and inform effective strategies for prevention and intervention.

Abstract
BACKGROUND Inpatient postpartum recovery trajectories following cesarean delivery and spontaneous vaginal delivery are underexplored. OBJECTIVE This study primarily aimed to compare recovery following cesarean delivery and spontaneous vaginal delivery in the first postpartum week, and secondarily to evaluate psychometrically the Japanese version of the Obstetric Quality of Recovery-10 scoring tool. STUDY DESIGN Following institutional review board approval, the EQ-5D-3L (EuroQoL 5-Dimension 3-Level) questionnaire and a Japanese version of the Obstetric Quality of Recovery-10 measure were used to evaluate inpatient postpartum recovery in uncomplicated nulliparous parturients delivering via scheduled cesarean delivery or spontaneous vaginal delivery. RESULTS A total of 48 and 50 women who delivered via cesarean delivery and spontaneous vaginal delivery, respectively, were recruited. Women delivering via scheduled cesarean delivery experienced significantly worse quality of recovery on days 1 and 2 compared with those who had spontaneous vaginal delivery. Quality of recovery significantly improved daily, plateauing at days 4 and 3 for cesarean delivery and spontaneous vaginal delivery groups, respectively. Compared with cesarean delivery, spontaneous vaginal delivery was associated with prolonged time to analgesia requirement, decreased opioid consumption, reduced antiemetic requirement, and reduced times to liquid/solid intake, ambulation, and discharge. Obstetric Quality of Recovery-10-Japanese is a valid (correlates with the EQ-5D-3L including a global health visual analog scale, gestational age, blood loss, opioid consumption, time until first analgesic request, liquid/solid intake, ambulation, catheter removal, and discharge), reliable (Cronbach alpha=0.88; Spearman-Brown reliability estimate=0.94; and intraclass correlation coefficient=0.89), and clinically feasible (98% 24-hour response rate) measure. CONCLUSION Inpatient postpartum recovery is significantly better in the first 2 postpartum days following spontaneous vaginal delivery compared with scheduled cesarean delivery. Inpatient recovery is largely achieved within 4 and 3 days following scheduled cesarean delivery and spontaneous vaginal delivery, respectively. Obstetric Quality of Recovery-10-Japanese is a valid, reliable, and feasible measure of inpatient postpartum recovery.

Abstract
Soil contamination by arsenic (As) poses potential health risks to humans. As-hyperaccumulator P. vittata has been used in As-contaminated soils for phytoremediation. Clarifying the mechanisms of its As-hyperaccumulation is critical to enhance its efficiency in phytoremediation. Here, based on transcriptome analysis, we determined the concentration-dependent patterns of As-related gene families by comparing As-hyperaccumulator P. vittata and non-hyperaccumulator P. ensiformis after exposing to 20 µM arsenate (AsV). As expected, arsenic induced more stress in P. ensiformis than P. vittata. Based on gene ontology, differences in transporter activity are probably responsible for their differential As accumulation. Though As exposure induced expression of phosphate transporter PvPht1;4 for AsV absorption in both plants, stronger AsV reduction, AsIII transport, and AsIII-GSH complexation were found in P. ensiformis roots. Unlike P. ensiformis, As metabolism processes occurred mainly in P. vittata fronds. Notably, tonoplast-localized ACR3s were only present in P. vittata, making it more effective in sequestrating AsIII into frond vacuoles. Further, vesicle As transformation via PvGAPC1 (glyceraldehyde 3-phosphate dehydrogenase), PvOCT4 (organic cation transporter 4), and PvGSTF1 (glutathione S-transferase) contributed little to As-hyperaccumulation. This study provides information on critical genes responsible for As-hyperaccumulation by P. vittata, which can be applied to construct As-hyperaccumulating plants by genetic engineering to enhance their phytoremediation efficiency in As-contaminated soils.

Abstract
The present study aimed to investigate the occurrence of chromosomal karyotype abnormalities and azoospermia factor (AZF) microdeletion on the long arm of the Y chromosome (Yq) in infertile men, and to determine their association with infertility to ultimately improve clinical outcomes in these patients. A total of 1,980 azoospermic and oligospermic men from the outpatient department of the Fujian Maternity and Child Health Hospital (Fuzhou, China) were recruited between January 2016 and December 2019. Peripheral blood was used for karyotype analysis; AZF microdeletion analysis of the Yq was performed using capillary electrophoresis. Among the 1,980 patients, 178 had chromosomal abnormalities (9.0%; 178/1,980), of whom 98 had an abnormal number of chromosomes. Among the abnormal karyotypes, the most common was 47, XXY (80/178; 44.9%). AZF microdeletion on the Yq occurred at a rate of 10.66% (211/1,980); the most common type was the AZFb/c deletion (sY1192; 140/211; 66.4%). The present findings showed that karyotype abnormalities and AZF gene microdeletion are important drivers of male infertility. Specifically, men with Yqh- and del(Y)(q11) had a higher risk of AZF microdeletion. These results suggested that patient treatment could be personalized based on routine molecular genetic analysis, which could further alleviate the economic and emotional burden of undergoing redundant or ineffective treatments.

Abstract
BACKGROUND The genetic etiology of congenital pulmonary stenosis (PS) in fetuses remains inadequately studied. We used karyotype analysis and chromosomal microarray analysis (CMA) to investigate the genetic aberrations associated with PS in human fetuses. METHODS A retrospective analysis was performed on 84 fetuses with congenital PS in southern China. Fetal amniotic fluid and umbilical cord blood samples were obtained for chromosomal karyotype analysis and CMA. RESULTS The rate of pathogenic copy number variation (CNV) was 15.5% (13/84) after karyotyping and CMA. An abnormal karyotype was detected in five cases (6.0%, 5/84) via karyotyping, whereas pathogenic CNVs were detected in 13 cases (15.5%, 13/84) via CMA. In addition to the five abnormal karyotypes detected using karyotype analysis, eight additional chromosomal microduplications and microdeletions were detected using CMA, comprising three cases of 22q11.21 microdeletion; two cases of 16p11.2 microdeletion; one case of simultaneous 18q23 microdeletion and 22q13.33 microduplication; one case of 15q24.1q24.2 microdeletion; and one case of 1q21.1q21.2 microduplication. The rate of pathogenic CNV occurrence was 11.5% in fetuses with isolated PS and 17.2% in fetuses with PS combined with other ultrasound abnormalities. This difference between the two experimental groups was statistically significant. Among 84 fetuses with PS, 39 pregnancies were terminated, and five were lost to follow-up. CONCLUSIONS CMA was not only conducive to detect PS-related pathogenic genomic abnormalities but also to accurately evaluate fetal prognosis in genetic counseling. The early detection of PS and genomic abnormalities will exerta positive impact on fetal intervention and the related prognosis of PS in perinatal infants.

Abstract
Cadmium (Cd) pollution threatens food security and the environment. Willow species (Salix, Salicaceae) exhibit a remarkable potential to restore Cd-polluted sites due to their high biomass production and high Cd accumulation capacities. This study examined the Cd accumulation and tolerance in 31 genotypes of shrub willow in hydroponic conditions at varying Cd levels (0 μM Cd, 5 μM Cd, and 20 μM Cd). The root, stem, and leaf biomass of 31 shrub willow genotypes showed significant differences to Cd exposure. Among 31 willow genotypes, four patterns of biomass variation response to Cd were identified: insensitive to Cd; growth inhibition due to excessive Cd supply (high Cd inhibition); low Cd causing inhibited growth, whereas high Cd leading to increased biomass (U-shape); and growth increment with excessive Cd exposure (high Cd induction). The genotypes belonging to the "insensitive to Cd" and/or "high Cd induction" were candidates for the utilization of phytoremediation. Based on the analysis of Cd accumulation of 31 shrub willow genotypes at high and low Cd levels, genotypes 2372, 51-3, and 1052 obtained from a cross between S. albertii and S. argyracea grew well and accumulated relatively more Cd levels than other genotypes. In addition, for Cd-treated seedlings, root Cd accumulation was positively correlated with shoot Cd accumulation and total Cd uptake, demonstrating that Cd accumulation in roots could serve as a biomarker for evaluating the Cd extraction capacity of willows, especially in hydroponics screening. The results of this study screened out willow genotypes with high Cd uptake and translocation capacities, which will provide valuable approaches for restoring Cd-contaminated soils with willows.

Abstract
To better understand outcomes in postpartum patients who receive peripartum anaesthetic interventions, we aimed to assess quality of recovery metrics following childbirth in a UK-based multicentre cohort study. This study was performed during a 2-week period in October 2021 to assess in- and outpatient post-delivery recovery at 1 and 30 days postpartum. The following outcomes were reported: obstetric quality of recovery 10-item measure (ObsQoR-10); EuroQoL (EQ-5D-5L) survey; global health visual analogue scale; postpartum pain scores at rest and movement; length of hospital stay; readmission rates; and self-reported complications. In total, 1638 patients were recruited and responses analysed from 1631 (99.6%) and 1282 patients (80%) at one and 30 days postpartum, respectively. Median (IQR [range]) length of stay postpartum was 39.3 (28.5-61.0 [17.7-513.4]), 40.3 (28.5-59.1 [17.8-220.9]), and 35.9 (27.1-54.1 [17.9-188.4]) h following caesarean, instrumental and vaginal deliveries, respectively. Median (IQR [range]) ObsQoR-10 score was 75 ([62-86] 4-100) on day 1, with the lowest ObsQoR-10 scores (worst recovery) reported by patients undergoing caesarean delivery. Of the 1282 patients, complications within the first 30 days postpartum were reported by 252 (19.7%) of all patients. Readmission to hospital within 30 days of discharge occurred in 69 patients (5.4%), with 49 (3%) for maternal reasons. These data can be used to inform patients regarding expected recovery trajectories; facilitate optimal discharge planning; and identify populations that may benefit most from targeted interventions to improve postpartum recovery experience.

Abstract
We propose and demonstrate a high-performance distributed dynamic absolute strain sensing technique by synthesizing φ-OTDR and BOTDR. The technique synthesizes the relative strain obtained by the φ-OTDR part and the initial strain offset estimated by fitting the relative strain with the absolute strain signal from the BOTDR part. As a result, it provides not only the characteristics of high sensing accuracy and high sampling rate like φ-OTDR, but also the absolute strain measurement and the large sensing dynamic range like BOTDR. The experiment results indicate the proposed technique can realize the distributed dynamic absolute strain sensing with a sensing dynamic range of over 2500 µɛ, a peak-to-peak amplitude of 1165 µɛ, and a wide frequency response range from 0.1 to over 30 Hz over a sensing range of about 1 km.

Abstract
OBJECTIVE A simple, rapid, and specific method has been developed and validated to measure sulbactam in human plasma using high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). MATERIALS AND METHODS The pharmacokinetic characteristics of sulbactam in critically ill patients with augmented renal clearance were investigated after the repeated administration of cefoperazone-sulbactam (3 g, q8, IV drip, combination ratio of 2 : 1). Sulbactam plasma concentration was determined using LC-MS/MS with tazobactam used as an internal standard (IS). RESULTS The method was fully validated with a sensitivity of 0.20 μg/mL, the linear concentration was ranged from 0.20 to 30.0 μg/mL. The intra-batch precision (RSD%) was less than 4.9%, and the accuracy deviation (RE%) ranged from -9.9 to 1.0%; the inter-batch precision (RSD%) was less than 6.2%, and the accuracy deviation (RE%) ranged from -9.2% to 3.7%. The value of the mean matrix factor at the low and high quality control (QC) concentration was 96.8 and 101.0%, respectively. The extraction recovery for QCL and QCH of sulbactam were 92.5 and 87.5%, respectively. Plasma samples and clinical data were collected at 0 (pre dose), 0.25, 0.5, 1, 2, 3, 6, and 8 hours (post dose) from 11 critically ill patients. Pharmacokinetic parameters were determined by non-compartmental analysis (NCA) using Phoenix WinNonlin software. CONCLUSION This method was successfully applied to study the pharmacokinetics of sulbactam for critically ill patients. The main pharmacokinetic parameters of sulbactam in augmented renal function and normal renal function groups were summarized as follows: half-life, 1.45 ± 0.66 and 1.72 ± 0.58 hours, area under the concentration-time curve from 0 to 8 hours, 59.1 ± 20.1 and 111.4 ± 23.2 μg × h/mL, drug plasma clearance at steady state, 18.9 ± 7.5 and 9.32 ± 2 .03 L/h, respectively. These results suggested that a higher dose of sulbactam should be used in critically ill patients with augmented renal clearance.

Abstract
In this paper, we propose an adaptive path tracking algorithm based on the BP (back propagation) neural network to increase the performance of vehicle path tracking in different paths. Specifically, based on the kinematic model of the vehicle, the front wheel steering angle of the vehicle was derived with the PP (Pure Pursuit) algorithm, and related parameters affecting path tracking accuracy were analyzed. In the next step, BP neural networks were introduced and vehicle speed, radius of path curvature, and lateral error were used as inputs to train models. The output of the model was used as the control coefficient of the PP algorithm to improve the accuracy of the calculation of the front wheel steering angle, which is referred to as the BP-PP algorithm in this paper. As a final step, simulation experiments and real vehicle experiments are performed to verify the algorithm's performance. Simulation experiments show that compared with the traditional path tracking algorithm, the average tracking error of BP-PP algorithm is reduced by 0.025 m when traveling at a speed of 3 m/s on a straight path, and the average tracking error is reduced by 0.27 m, 0.42 m, and 0.67 m, respectively, at a speed of 1.5 m/s with a curvature radius of 6.8 m, 5.5 m, and 4.5 m, respectively. In the real vehicle experiment, an electric patrol vehicle with an autonomous tracking function was used as the experimental platform. The average tracking error was reduced by 0.1 m and 0.086 m on a rectangular road and a large curvature road, respectively. Experimental results show that the proposed algorithm performs well in both simulation and actual scenarios, improves the accuracy of path tracking, and enhances the robustness of the system. Moreover, facing paths with changes in road curvature, the BP-PP algorithm achieved significant improvement and demonstrated great robustness. In conclusion, the proposed BP-PP algorithm reduced the interference of nonlinear factors on the system and did not require complex calculations. Furthermore, the proposed algorithm has been applied to the autonomous driving patrol vehicle in the park and achieved good results.

Abstract
Numerous studies have evaluated the use of single nucleotide polymorphism array (SNP-array) in prenatal diagnostics, but very few have evaluated its application under different risk conditions. Here, SNP-array was used for the retrospective analysis of 8386 pregnancies and the cases were categorized into seven groups. Pathogenic copy number variations (pCNVs) were found in 699 (8.3%, 699/8386) cases. Among the seven different risk factor groups, the non-invasive prenatal testing-positive group had the highest pCNVs rate (35.3%), followed by the abnormal ultrasound structure group (12.8%), and then the chromosomal abnormalities in the couples group (9.5%). Notably the adverse pregnancy history group presented with the lowest pCNVs rate (2.8%). Further evaluation of the 1495 cases with ultrasound abnormalities revealed that the highest pCNV rates were recorded in those cases with multiple system structure abnormalities (22.6%), followed by the groups with skeletal system (11.6%) and urinary system abnormalities (11.2%). A total of 3424 fetuses with ultrasonic soft markers were classified as having one, two, or three ultrasonic soft markers. The different pCNV rates in the three groups were statistically significant. There was little correlation between pCNVs and a previous history of adverse pregnancy outcomes, suggesting that genetic screening under these conditions should be evaluated on a case-by-case basis.

Abstract
Bombyx mori cypovirus 1 (BmCPV1), a primary pathogen of the silkworm, is a typical dsRNA virus belonging to the Reoviridae family. In this study, a total of 2520 differentially expressed genes (DEGs) were identified by RNA-seq analysis of the silkworm midgut after BmCPV1 infection and Gene Ontology (GO) functional annotation showed that the DEGs predominantly functioned in binding (molecular function), cell (cellular component), and cellular processes (biological process). Additionally, the Kyoto Encyclopedia of Genes and Genomes (KEGG) functional annotation revealed that the DEGs were mainly distributed in global and overview metabolism maps, translation, and signal transduction. Among the identified DEGs, BmPGRP-S5 belongs to the peptidoglycan recognition protein (PGRP) family. Previous studies have revealed that PGRPs were involved in the interactions between silkworm and BmCPV1. Here, we explored the effect of BmPGRP-S5 on BmCPV1 replication and demonstrated that BmPGRP-S5 promotes the proliferation of BmCPV1 in BmN cells through overexpression or knockdown experiments. Knocking down of BmPGRP-S5 in silkworm larvae similarly promoted the proliferation of BmCPV1. Through experimental validation, we therefore determined that BmPGRP-S5 acts as a proviral host factor for BmCPV1 infection. This study clarifies the proliferation mechanism of BmCPV1 and provides new insights into the functional role of BmPGRP-S5.

Abstract
BACKGROUND Head and neck squamous cell carcinoma (HNSCC) is a multisite malignancy that responds well to immunotherapy. Despite the initial enthusiasm, the clinical benefits of immunotherapy in HNSCC patients are overall limited. Endoplasmic reticulum stress (ERS) has been indicated to play a key role in the process of anti-tumor immune response mediation. However, ERS-related biomarkers which can accurately predict prognosis and immunotherapy response in HNSCC are still lacking. METHODS AND RESULTS In this study, we identify and validate an ERS-related signature comprises of six genes (ASNS, EXOSC6, BAK1, TPP1, EXOSC8, and TATDN2) that can predict the prognosis of HNSCC patients. GSEA analysis indicates that the ERS-related signature is significantly correlated with tumor immunity in HNSCC. Moreover, the infiltration of naive B cells and CD8 + T cells are significantly diminished in patients with high-risk scores compared to those with low-risk scores, while macrophages and activated mast cells are remarkably enhanced. Furthermore, the ERS-related signature also displays a tremendous potential for predicting immunotherapy response in HNSCC. CONCLUSIONS Our study identifies an ERS-related signature that can predict the prognosis of HNSCC patients and highlights its potential value as a predictive biomarker of immunotherapy response, potentially enabling more precise and personalized immunotherapy response and paving the way for further investigation of the prognostic and therapeutic potentials of ERS.

Abstract
We experimentally demonstrate a narrow linewidth semiconductor multi-wavelength distributed feedback (DFB) laser array by simultaneously injection locking each laser to the corresponding resonance of a single on-chip microring resonator. The white frequency noises of all the DFB lasers is reduced by more than 40 dB once they are simultaneously injection locked to a single microring resonator with a quality factor (Q-factor) of 2.38 million. Correspondingly, the instantaneous linewidths of all the DFB lasers are narrowed by a factor of 104. In addition, frequency combs originating from non-degenerate four-wave mixing (FWM) between the locked DFB lasers are also observed. Simultaneously injection locking multi-wavelength lasers to a single on-chip resonator may enable the possibilities of integrating a narrow-linewidth semiconductor laser array on a single chip and having multiple microcombs in a single resonator, which are in high demand in wavelength division multiplexing coherent optical communication systems and metrological applications.

Abstract
BACKGROUND Most of the 1.1 million women who deliver by cesarean in the United States each year have an uncomplicated recovery. However, severe pain resistant to standard multimodal therapy within the first days after surgery is associated with an increased risk for prolonged pain and opioid use. The best outpatient management for parturients with severe resistant early onset pain is not known. METHODS We performed a prospective, double-blind, placebo-controlled, randomized trial of up to 12 weeks of outpatient treatment with gabapentin to evaluate its effectiveness to facilitate opioid cessation in women with at least 2 reports of severe pain during the immediate postpartum period resistant to standard multimodal pain management. Time to opioid cessation was the primary outcome. Time to pain resolution; time to discontinuation of gabapentin, acetaminophen, and ibuprofen; time to self-reported recovery; and National Institute of Health Patient-Reported Outcomes System (PROMIS) surveys for anxiety, depression, fatigue, and physical function were assessed as secondary outcomes. RESULTS There was no difference in time to opioid cessation between patients who were randomly assigned to be treated with gabapentin (Kaplan-Meier estimated median of 2 [25th-75th percentiles of 1-3] weeks, n = 35) versus those who were treated with placebo (2 [1-3] weeks, n = 35). The hazard ratio was 1.1 (95% confidence interval [CI], 0.67-1.8), P = .65. There were no differences in any secondary end points between the study groups. CONCLUSIONS Outpatient supplementation with gabapentin did not reduce time to opioid cessation, pain, anxiety, depression, fatigue, or improve physical function in women with severe pain after cesarean delivery. Gabapentin should not be routinely added to the standard outpatient multimodal regimen of ibuprofen, acetaminophen, and opioids.

Abstract
Humoral immunity confers protection against COVID-19. The longevity of antibody responses after receiving an inactivated vaccine in individuals with previous SARS-CoV-2 infection is unclear. Plasma samples were collected from 58 individuals with previous SARS-CoV-2 infection and 25 healthy donors (HDs) who had been vaccinated with an inactivated vaccine. The neutralizing antibodies (NAbs) and S1 domain-specific antibodies against the SARS-CoV-2 wild-type and Omicron strains and nucleoside protein (NP)-specific antibodies were measured using a chemiluminescent immunoassay. Statistical analysis was performed using clinical variables and antibodies at different timepoints after SARS-CoV-2 vaccination. NAbs targeting the wild-type or Omicron strain were detected in individuals with previous SARS-CoV-2 infection at 12 months after infection (wild-type: 81%, geometric mean (GM): 20.3 AU/mL; Omicron: 44%, GM: 9.4 AU/mL), and vaccination provided further enhancement of these antibody levels (wild-type: 98%, GM: 53.3 AU/mL; Omicron: 75%, GM: 27.8 AU/mL, at 3 months after vaccination), which were significantly higher than those in HDs receiving a third dose of inactivated vaccine (wild-type: 85%, GM: 33.6 AU/mL; Omicron: 45%, GM: 11.5 AU/mL). The level of NAbs in individuals with previous infection plateaued 6 months after vaccination, but the NAb levels in HDs declined continuously. NAb levels in individuals with previous infection at 3 months post-vaccination were strongly correlated with those at 6 months post-vaccination, and weakly correlated with those before vaccination. NAb levels declined substantially in most individuals, and the rate of antibody decay was negatively correlated with the neutrophil-to-lymphocyte ratio in the blood at discharge. These results suggest that the inactivated vaccine induced robust and durable NAb responses in individuals with previous infection up to 9 months after vaccination.
