Abstract
Objective: To understand the current status of anemia, iron deficiency, and iron-deficiency anemia among preschool children in China. Methods: A cross-sectional study was conducted with a multi-stage stratified sampling method to select 150 streets or townships from 10 Chinese provinces, autonomous regions, or municipalities (East: Jiangsu, Zhejiang, Shandong, and Hainan; Central: Henan; West: Chongqing, Shaanxi, Guizhou, and Xinjiang; Northeast: Liaoning). From May 2022 to April 2023, a total of 21 470 children, including community-based children aged 0.5 to<3.0 years receiving child health care and kindergarten-based children aged 3.0 to<7.0 years, were surveyed. They were divided into 3 age groups: infants (0.5 to<1.0 year), toddlers (1.0 to<3.0 years), and preschoolers (3.0 to<7.0 years). Basic information such as sex and date of birth of the children was collected, and peripheral blood samples were obtained for routine blood tests and serum ferritin measurement. The prevalence rates of anemia, iron deficiency, and iron-deficiency anemia were analyzed, and the prevalence rate differences were compared among different ages, sex, urban and rural areas, and regions using the chi-square test. Results: A total of 21 460 valid responses were collected, including 10 780 boys (50.2%). The number of infants, toddlers, and preschoolers were 2 645 (12.3%), 6 244 (29.1%), and 12 571 (58.6%), respectively. The hemoglobin level was (126.7±14.8) g/L, and the serum ferritin level was 32.3 (18.5, 50.1) μg/L. The overall rates of anemia, iron deficiency, and iron-deficiency anemia were 10.4% (2 230/21 460), 28.3% (6 070/21 460), and 3.9% (845/21 460), respectively. The prevalence rate of anemia was higher for boys than for girls (10.9% (1 173/10 780) vs. 9.9% (1 057/10 680), χ2=5.58, P=0.018), with statistically significant differences in the rates for infants, toddlers and preschoolers (18.0% (475/2 645), 10.6% (662/6 244), and 8.7% (1 093/12 571), respectively, χ2=201.81, P<0.01), and the rate was significantly higher for children in rural than that in urban area (11.8% (1 516/12 883) vs. 8.3% (714/8 577), χ2=65.54, P<0.01), with statistically significant differences in the rates by region (χ2=126.60, P<0.01), with the highest rate of 15.8% (343/2 173) for children in Central region, and the lowest rate of 5.3% (108/2 053) in Northeastern region. The prevalence rates of iron deficiency were 33.8% (895/2 645), 32.2% (2 011/6 244), and 25.2% (3 164/12 571) in infants, toddlers, and preschoolers, respectively, and 30.0% (3 229/10 780) in boys vs. 26.6% (2 841/10 680) in girls, 21.7% (1 913/8 821), 40.0% (870/2 173), 27.1% (2 283/8 413), 48.9% (1 004/2 053) in Eastern, Central, Western, and Northeastern regions, respectively, and each between-group showed a significant statistical difference (χ2=147.71, 29.73, 773.02, all P<0.01). The prevalence rate of iron-deficiency anemia showed a significant statistical difference between urban and rural areas, 2.9% (251/8 577) vs. 4.6% (594/12 883) (χ2=38.62, P<0.01), while the difference in iron deficiency prevalence was not significant (χ2=0.51, P=0.476). Conclusions: There has been a notable improvement in iron deficiency and iron-deficiency anemia among preschool children in China, but the situation remains concerning. Particular attention should be paid to the prevention and control of iron deficiency and iron-deficiency anemia, especially among infants and children in the Central, Western, and Northeastern regions of China.

Abstract
INTRODUCTION Urinary incontinence (UI) is one of the most common chronic diseases among women, which can endanger their physical and mental health and incur a heavy financial burden on both individuals and society. Web-based interventions (WBIs) have been applied to manage women's UI, but their effectiveness has remained inconclusive. This systematic review and meta-analysis aims to explore the effectiveness of WBIs on self-reported symptom severity, condition-specific quality of life, adherence to pelvic floor muscle training (primary outcomes) and other extensive secondary outcomes among women with UI. We also aimed to investigate whether intervention characteristics (format, interactivity and main technology) have impacts on the effectiveness of primary outcomes. METHODS AND ANALYSIS This systematic review protocol was developed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols guidelines. 10 electronic databases will be comprehensively searched from their inception to 1 May 2024, along with grey literature searches and manual reviews of relevant reference lists to identify eligible randomised controlled trials. The methodological quality of the included studies will be assessed by two reviewers based on the Cochrane Risk of Bias Tool. Meta-analyses will be conducted via Stata V.12.0. Leave-one-out sensitivity analyses will be performed, and publication bias will be evaluated using funnel plots and Egger's test. Subgroup analyses regarding intervention format, interactivity and main technology will be carried out. ETHICS AND DISSEMINATION No ethics approval is needed for this review since no primary data are to be collected. The results of this review will help develop an optimal WBI for women with UI, thereby providing them with maximum benefits. The findings will be disseminated via a peer-reviewed journal or conference presentation. PROSPERO REGISTRATION NUMBER CRD42023435047.

Abstract
OBJECTIVES The objectives were to assess (i) the quality of theory implementation, (ii) the application of behavior change techniques, and (iii) the effectiveness of theory-based interventions in promoting physical activity in pregnant women and improving maternal and neonatal outcomes. METHODS A systematic search was conducted across 8 databases (Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, EMBASE, MEDLINE, APA PsycINFO, PubMed, SPORTDiscus, and Web of Science) to identify randomized controlled trials published from database inception to 8 July 2023. The Cochrane risk-of-bias 2.0 tool was used to evaluate the quality of the included studies. The theory coding scheme was used to measure the quality of theory implementation, and behavior change techniques were coded according to behavior change taxonomy (version 1). The meta-analysis was performed using RevMan 5.3. The Grading of Recommendations, Assessment, Development, and Evaluation Approach was used to assess the certainty of evidence. RESULTS Eleven studies met the study criteria. Nine studies were based on one theory, while two studies were based on a combination of two theories. The quality of theory implementation was generally moderate. A total of 24 unique behavior change techniques were extracted. The most commonly used types of behavior change techniques were 'instruction on how to perform the behavior' (n = 9), 'goal setting' (behavior) (n = 8), 'action planning' (n = 7), and 'information about health consequences' (n = 7). Theory-based interventions significantly improved moderate-to-vigorous physical activity (standardized mean difference (SMD) = 0.17, 95 % confidence interval (CI) [0.04, 0.30], P = 0.01; moderate certainty of evidence), reduced the average gestational weight gain per week (mean difference (MD) = -0.06, 95 % CI [-0.11, -0.01], P = 0.02; moderate certainty of evidence), and decreased the incidence of gestational diabetes mellitus (risk ratio (RR) = 0.64, 95 % CI [0.46, 0.89], P = 0.008; high certainty of evidence). However, the effects of theory-based interventions on total physical activity, total gestational weight gain and the incidence of gestational hypertension and preterm delivery were unclear (P > 0.05). CONCLUSIONS (i) Most of the studies exhibited a moderate level of theory implementation quality. (ii) The use of theories varies, but common behavior change techniques were found across studies. (iii) Theory-based interventions can improve physical activity and maternal and neonatal outcomes and appear to be safe. Appropriate health behavior theories and behavior change techniques should be fully utilized in future interventions. REGISTRATION PROSPERO: CRD42023440886. TWEETABLE ABSTRACT Theory-based interventions can improve physical activity and maternal and neonatal outcomes and appear to be safe. Appropriate health behavior theories and behavior change techniques should be fully utilized in the development of future interventions.

Abstract
Periodontitis has been emphasized as a risk factor of insulin resistance-related systemic diseases. Accumulating evidence has suggested a possible "oral-gut axis" linking oral infection and extraoral diseases, but it remains unclear whether periodontal pathogens can survive the barriers of the digestive tract and how they play their pathogenic roles. The present study established a periodontitis mouse model through oral ligature plus Porphyromonas gingivalis inoculation and demonstrated that periodontitis aggravated diet-induced obesity and insulin resistance, while also causing P. gingivalis enrichment in the intestine. Metabolic labeling strategy validated that P. gingivalis could translocate to the gastrointestinal tract in a viable state. Oral administration of living P. gingivalis elicited insulin resistance, while administration of pasteurized P. gingivalis had no such effect. Combination analysis of metagenome sequencing and nontargeted metabolomics suggested that the tryptophan metabolism pathway, specifically indole and its derivatives, was involved in the pathogenesis of insulin resistance caused by oral administration of living P. gingivalis. Moreover, liquid chromatography-high-resolution mass spectrometry analysis confirmed that the aryl hydrocarbon receptor (AhR) ligands, mainly indole acetic acid, tryptamine, and indole-3-aldehyde, were reduced in diet-induced obese mice with periodontitis, leading to inactivation of AhR signaling. Supplementation with Ficz (6-formylindolo (3,2-b) carbazole), an AhR agonist, alleviated periodontitis-associated insulin resistance, in which the restoration of gut barrier function might play an important role. Collectively, these findings reveal that the oral-gut translocation of viable P. gingivalis works as a fuel linking periodontitis and insulin resistance, in which reduction of AhR ligands and inactivation of AhR signaling are involved. This study provides novel insight into the role of the oral-gut axis in the pathogenesis of periodontitis-associated comorbidities.

Abstract
BACKGROUND Lower urinary tract symptoms (LUTS) are prevalent and distressing concerns for women worldwide. The prevalence of LUTS reaches the first peak during pregnancy and postnatal period. However, less attention has been paid to LUTS around childbirth and little progress has been made in the prevention of LUTS. Understanding the epidemiological characteristics of LUTS around childbirth would inform decision making for health care providers and perinatal women in the prevention of LUTS. The study aims to investigate the epidemiological trends and associated risk factors related to LUTS around childbirth. METHODS Pregnant women were consecutively enrolled during pregnancy in the obstetrical wards of a tertiary hospital and followed up at 6-8 weeks and one year postpartum through a prospective design. Urinary incontinence was assessed with the International Consultation on Incontinence Modular Questionnaire-Urinary Incontinence Short Form. Other symptoms were measured with questions based on definitions of the International Incontinence Society. Multiple logistic regression was used to examine the risk factors for LUTS including urinary incontinence, increased daytime frequency, nocturia and urgency. The report followed the STROBE statement. RESULTS A total of 1243 pregnant women participated in this study. The prevalence of at least one type of storage symptoms was 94%, 55% and 35% in late pregnancy, at 6-8 weeks and one year postpartum, respectively. The prevalence of urinary incontinence remained at 21% within one year postpartum. The majority of the participants suffered from mild to moderate urinary incontinence. Age, job, BMI before pregnancy, gestational diabetes mellitus, urinary tract infection history, previous history of LUTS, age at first birth and birth mode were predictors of LUTS one year postpartum. CONCLUSION LUTS were highly prevalent during pregnancy and postnatal period. The prevalence of urinary incontinence was more stable than that of other LUTS within one year postpartum. Women aged more than 35 years, engaging in manual work, with gestational diabetes mellitus, with a history of urinary tract infection and LUTS, with advanced age at first birth and vaginal delivery were more likely to suffer from LUTS postpartum. The findings provided a novel and deep insight into the epidemiological trends and related risk factors of LUTS around childbirth.

Abstract
PURPOSE/OBJECTIVE(S) Spatially fractionated radiation therapy (Lattice) delivers ablative doses to metastatic and/or unresectable tumors with a curative or palliative goal. Through different forms of three-dimensional focusing, lattice forms several spherical high-dose areas(vertices) within the tumor, to produce a more obvious peak-valley effect and limit exposure to surrounding normal tissue. This study aimed to evaluate the efficacy and toxicity of patients with metastatic and/or bulky tumors treated with Lattice radiation. MATERIALS/METHODS Between April 2017 and February 2021, 76 patients with metastatic or bulky tumors treated with spatially-fractionated high-dose external beam radiation using the Lattice technique were included. A median dose of 15 Gy/1 fraction (range 10-45 Gy in 1/3 fractions) was delivered to the vertices in the gross tumor volumes (GTV). 46 patients were treated with Lattice radiation combined with conventional fractionated external irradiation, and 30 patients were treated with Lattice alone. Patients were evaluated for clinical response, survival, and toxicity. RESULTS A total of 76 patients with 85 sites were included in the analysis, 63 (82.9%) patients had metastatic diseases. Median GTV was 138.6cc (range 4.9-3784.1cc) in volume and 6.2 cm (range:2.3-21.4cm) in greatest axial diameter. 38 tumors were in the thorax, 13 abdomen/pelvis, 19 metastatic lymph nodes, 8 bone, 5 head and neck, and 2 extremities. The median follow-up was 11.6 months (range 1.27-57.37 months). At the time of analysis, 23 patients (29.9%) were alive, without the progression of disease. 90.7% of the deceased patients died of disease progression. Median overall survival (OS) was 11.4 months (95% CI: 8.4-17.6), the 1-year OS and cancer specific survival were 46.8% and 48.7% respectively. The disease control rate (DCR) was 91.8%, including 2.4% complete remission, 48.2% partial remission, and 41.2% stable disease. Symptomatic improvement was observed in 98.7% of patients. No mortality was associated with Lattice therapy. There was no treatment-associated acute or late grade 3+ toxicity. CONCLUSION Lattice radiation is feasible and well-tolerated in the treatment of metastatic and/or bulky diseases, and may provide a high DCR. In light of these preliminary results, it seems that this therapy may be a new paradigm for treating patients with advanced cancers.

Abstract
INTRODUCTION Regular physical activity during pregnancy is effective in preventing diseases and promoting the health outcomes of mothers and babies. However, the level of physical activity among them is not ideal. Especially in China, the proportion of pregnant women who meet the recommendation of physical activity in the guidelines is even lower. Thus, we aim to evaluate the prevalence of meeting physical activity recommendation and its influencing factors during pregnancy in China. METHODS AND ANALYSIS This protocol is developed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols guidelines. PubMed, Web of Science, Scopus, CINAHL, MEDLINE, PsycINFO, EMBASE, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (Weipu) and WanFang Data will be comprehensively searched by two reviewers. Studies that report the prevalence of Chinese pregnant women meeting physical activity recommendation will be included. Two reviewers will independently assess eligibility, extract data and evaluate methodological quality. Data including authors, publication years, language, geographical region, tools, trimesters, prevalence and influence factors will be extracted. Data will be analysed by Stata V.11 statistical software. ETHICS AND DISSEMINATION No formal ethics approval is required for this protocol and no primary data are to be collected. Findings from this review may be useful to develop interventions for the physical activity of pregnant women in China. The results will be disseminated through peer-reviewed journals, conference presentations and public events. PROSPERO REGISTRATION NUMBER CRD42022372722.

Abstract
Objective: To evaluate the efficacy of gonadotropin-releasing hormone agonist (GnRH-a) pretreatment before total hysterectomy for adenomyosis patients with uterine volume ≥12 gestational weeks and moderate or severe anemia. Methods: From January 2018 to March 2023, 689 patients who underwent total hysterectomy for adenomyosis in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. According to the preoperative medication, they were divided into study group (127 cases) and control group (562 cases). Patients in the study group underwent GnRH-a pretreatment for 3 cycles before surgery, and the control group received operation directly. SPSS 26.0 software was used to perform 1∶1 matching for the two groups of patients through the propensity score matching method. Matching variables included age, body mass index, gravidity, parity, history of pelvic and abdominal surgery, menstrual cycle, menstrual period, dysmenorrhea score, initial diagnosis of cancer antigen 125 (CA125), uterine volume and hemoglobin value. The dysmenorrhea score, uterine volume, hemoglobin value and CA125 level before and after GnRH-a pretreatment in the study group were compared. And the duration of operation, intraoperative blood loss, postoperative white blood cell count, perioperative blood transfusion cases, postoperative disease rate, duration of hospitalization, total hospitalization cost between the two groups were compared. Results: With propensity score matching, 119 patients in the study group and 119 patients in the control group were finally enrolled in this study. In the study group, before and after the treatment with GnRH-a, the dysmenorrhea score (7.4±1.7 vs 5.6±1.8), uterine volume [(362±160) vs (233±126) cm3], hemoglobin value [(74.1±10.7) vs (102.5±13.5) g/L], and CA125 level [(104±76) vs (64±51) kU/L] were statistically different (all P<0.05). There were statistical differences of operation time [(86±18) vs (116±31) minutes], intraoperative blood loss [(24±9) vs (43±22) ml], white blood cell count after 1 day of operation [(9.80±0.10)×109/L vs (9.90±0.10)×109/L], number of perioperative blood transfusion case [5.9% (7/119) vs 61.3% (73/119)], postoperative disease rate [5.0% (6/119) vs 16.0% (19/119)], hospitalization duration [(7.1±1.6) vs (7.9±1.6) days], and total hospitalization cost [(35 323±5 275) vs (37 159±5 640) yuan] between the study group and the control group (all P<0.05). Conclusion: The pretreatment of using GnRH-a before total hysterectomy for adenomyosis patients with uterine volume ≥12 gestational weeks and moderate or severe anemia is not only conducive to improving dysmenorrhea, signs of anemia, reducing uterine volume, but also conducive to the implementation of surgery, reducing intraoperative and postoperative complications, and reducing hospital costs.

Abstract
BACKGROUND Stress urinary incontinence during pregnancy is closely related to the occurrence of postpartum and long-term urinary incontinence. Early pelvic floor management is of great significance in promoting the recovery of pelvic floor tissues in pregnant women. However, effective management of urinary incontinence is far from achievable owing to the low adherence of pregnant women in partaking in pelvic floor rehabilitation. As a comprehensive framework for behavioural theory, the Theoretical Domain Framework allows for comprehensive identification of behavioural determinants. Using Theoretical Domain Framework, this study aimed to identify barriers and enablers of pelvic floor rehabilitation behaviours in pregnant women with stress urinary incontinence. METHODS A descriptive, qualitative design was used in this study. Face-to-face semi-structured interviews were conducted with pregnant women with stress urinary incontinence based on the Theoretical Domain Framework. The data were analysed using a combination of inductive and deductive methods. RESULTS Twenty pregnant women with stress urinary incontinence were interviewed. Seven themes were summarised and used to explain the pelvic floor rehabilitation behaviours of pregnant women with stress urinary incontinence. The seven themes were (1) individual knowledge and experience of pelvic floor management, (2) judgments about expected outcomes, (3) interactions of interpersonal situations, (4) environment, resources, and decision-making processes, (5) personal goal-setting and efforts towards behaviour change, (6) emotional influences on decision-making, and (7) personal characteristics. Besides the "Optimism" domain, 13 of the 14 Theoretical Domains Framework domains were found to influence pregnant patients' pelvic floor rehabilitation behaviours after deductive mapping of themes to the Theoretical Domains Framework. In addition, the inductive analysis generated a theme of personal characteristics that did not map to any of the Theoretical Domains Framework domains. CONCLUSIONS The pelvic floor rehabilitation behaviours of pregnant women with stress urinary incontinence are complex and are affected by many factors. The findings confirm the need for multiple interventions to support pelvic floor management in pregnant women with stress urinary incontinence, focusing on enhancing knowledge and skills in pelvic floor care and using appropriate behaviour change techniques (such as prompts) to provide a supportive environment.

Abstract
BACKGROUND Effective management of gestational diabetes mellitus (GDM) is essential because it is one of the most prevalent diseases during pregnancy, and the consequent condition maternal hyperglycemia is closely related to considerable short- and long-term maternal and neonatal complications. Web-based interventions (WBIs), defined as therapeutic interventions offered via the web, have been implemented to assist in managing GDM owing to their advantages of high accessibility and efficiency, but findings across relevant studies are inconsistent. OBJECTIVE This systematic review and meta-analysis aimed to evaluate the effectiveness of WBIs on glycemic control among pregnant women with GDM; examine whether specific types of intervention interactivity, format, and technology have beneficial effects on maternal glycemic control; and comprehensively assess the efficacy of WBIs in maternal behavioral outcomes, cognitive and attitudinal outcomes, mental health, maternal and neonatal clinical outcomes, and medical service use and costs among pregnant women with GDM. METHODS PubMed, Embase, Cochrane Library, Web of Science, CINAHL, and PsycINFO were searched from their respective inception to November 19, 2022, to identify relevant randomized controlled trials and controlled clinical trials. The methodological quality of the included studies was assessed using the Effective Public Health Practice Project tool. Where possible, the data for all outcomes were meta-analyzed using the Stata software (version 12.0; StataCorp). Overall, 3 subgroup analyses and post hoc sensitivity analyses of maternal glycemic control parameters were performed. RESULTS Overall, 25 publications arising from 21 randomized controlled trials and controlled clinical trials were included. The overall meta-analyses on glycemic control parameters demonstrated that WBIs could significantly improve fasting blood glucose (standardized mean difference=-1.764, 95% CI -2.972 to -0.557; P=.004) and 2-hour postprandial blood glucose (standardized mean difference=-1.433, 95% CI -2.561 to -0.304; P=.01) compared with the control group, whereas no significant effect was found on glycated hemoglobin and 1-hour postprandial blood glucose. The results of the subgroup analyses indicated that mobile app-delivered interventions with a personalized format and interactive function showed more beneficial effects on maternal glycemic control. Moreover, WBIs could significantly enhance compliance with the self-monitoring of blood glucose; increase the rate of normal vaginal delivery; and decrease the chance of emergency cesarean, admission to the neonatal intensive care unit, and composite neonatal complications. GDM knowledge, risk perception of the disease, self-efficacy, satisfaction with care, and medical service use of the participants in the WBI group were also improved compared with the control group. However, the effectiveness of WBIs on other secondary outcomes was either nonsignificant or uncertain. CONCLUSIONS WBIs are a promising approach to GDM management. Personalized, interactive, and mobile app-delivered interventions seem more worthy of being recommended for future clinical practice. Further high-quality studies are required to verify these findings before making broad recommendations.

Abstract
BACKGROUND AND AIM Fear of childbirth (FOC) is one of the most common mental health concerns among expectant fathers, which can cause adverse consequences for themselves and their families. A valid and accurate tool is the key to the identification of FOC. This study aimed to translate and culturally adapt the fathers' fear of childbirth scale (FFCS) into simplified Chinese and test the scale's psychometric properties among expectant fathers in mainland China. METHODS Researchers obtained translation permission and followed the multiphase translation guidelines to develop the Chinese version of the fathers' fear of childbirth scale (C-FFCS). Relevant psychometric properties were selected for the scale's psychometric validation on the basis of the Consensus-based Standards for the Selection of Health Status Measurement Instruments checklist. In this cross-sectional study, two samples of expectant fathers were collected in a university-affiliated hospital in Hangzhou between September and October 2022. RESULTS A total of 381 expectant fathers completed the C-FFCS, resulting in an effective response rate of 95.6%. The C-FFCS is a 3-factor structure consisting of 16 items, which explained 66.374% of the total variance. The content validity index of items ranged from 0.833 to 1.00, and the scale-level content validity index was 0.931. The confirmatory factor analysis confirmed the scale's 3-factor structure. Evidence of convergent validity (average variance extracted = 0.508-0.780) as well as discriminant validity offered excellent psychometric support. The Cronbach's α coefficient, McDonald's ω coefficient, intraclass correlation coefficient, Spearman-Brown coefficient, and Guttman split-half coefficient are within the satisfactory range (> 0.80). Significant correlations between the scores of the C-FFCS and Childbirth Attitude Questionnaire (r = 0.658, p < 0.01) and Fear of Birth Scale (r = 0.555, p < 0.01) both revealed good concurrent validity. The structure of C-FFCS was invariant across different parity groups, with no floor and ceiling effect. CONCLUSION The C-FFCS was demonstrated to be a sound instrument with good reliability and validity for measuring Chinese expectant fathers' FOC levels. However, further studies are advocated to verify the C-FFCS among a larger sample that is more representative of the Chinese expectant father population.

Abstract
BACKGROUND Physical activity (PA) brings many benefits to pregnant women and fetuses; however, the majority of pregnant women do not participate actively in PA during pregnancy. OBJECTIVES This study aimed to: (1) assess the utility of Multi-Theory Model (MTM) to explain the intentions of PA behavior in Chinese pregnant women; (2) analyze the predictors in initiating and maintaining PA behavior based on MTM. METHODS A cross-sectional study including pregnant women was conducted from March to June 2022 at a university hospital in Hangzhou, Zhejiang Province, China. Participants completed measures that included a self-developed demographic questionnaire and a 29-item MTM questionnaire. Descriptive statistics and stepwise multiple regression were used to analyze the data. The reliability was assessed by Cronbach's alpha and test-retest stability. The construct validity was evaluated by using exploratory factor (EFA) analysis and confirmatory factor analysis (CFA). RESULTS A total of 450 pregnant women participated in this study. The score of the magnitude of intention to initiate and maintain PA behavior during pregnancy was 2.30 (1.08) and 2.24 (1.09). The overall Cronbach's alpha value was 0.857. A four-factor structure for initiation model and a three-factor structure for maintenance model were determined. Results of the CFA confirmed construct validity of subscales (initiation model: χ2 = 206.123, df = 140, p < 0.001, χ2/df = 1.472, RMSEA = 0.046, SRMR = 0.0432, GFI = 0.913, CFI = 0.982; maintenance model: χ2 = 49.742, df = 29, p < 0.001, χ2/df = 1.715, RMSEA = 0.057, SRMR = 0.0432, GFI = 0.958, CFI 0.985). The result of regression indicated that participatory dialogue (β = 0.030; p = 0.002), behavioral confidence (β = 0.128; p < 0.001), changes in physical environment (β = 0.041; p = 0.005), trimester (β = -0.192; p = 0.001), and Gestational Diabetes Mellitus (GDM) (β = 0.408; p < 0.001) explained 52.1% variance in initiating PA behavior. Emotional transformation (β = 0.197; p < 0.001), practice for change (β = 0.083; p = 0.001), changes in social environment (β = 0.063; p < 0.001), pre-pregnancy exercise habit (β = -0.251; p = 0.001), and GDM (β = 0.298; p = 0.003) were significantly associated with pregnant women's intentions to maintain PA behavior and explained 49.1% variance. CONCLUSIONS The constructs of MTM were effective in explaining the intention to initiate and maintain PA behavior among Chinese pregnant women.

Abstract
Background and aim The postpartum depression literacy (PoDLi) of perinatal women is closely related to the occurrence, recognition, and treatment of postpartum depression, therefore valid instruments for evaluating the level of PoDLi are of great significance for both research and clinical practice. This study aimed to cross-culturally adapt the postpartum depression literacy scale (PoDLiS) into Chinese and to test its psychometric properties among Chinese perinatal women. Materials and methods A cross-sectional study was conducted from April to May 2022 in a tertiary hospital in Hangzhou, Zhejiang Province, China. 619 out of the 650 perinatal women that were approached via a convenience sampling method completed the Chinese version of the PoDLiS (C-PoDLiS). Content validity [the content validity index of items (I-CVI) and scale-level content validity index (S-CVI)] was evaluated by an expert panel. Psychometric properties, including item analysis, structure validity (exploratory factor analysis, confirmatory factor analysis), convergent and discriminant validity, reliability (internal consistency, test-retest reliability), criterion validity (concurrent validity, predictive validity), and floor/ceiling effect were examined. Results The final version of C-PoDLiS is a six-factor structure consisting of 27 items, which explained 61.00% of the total variance. Adequate content validity (I-CVI = 0.833–1.00, S-CVI = 0.920) was ensured by the expert panel. The modified confirmatory factor analysis model revealed that the 6-factor model fitted the data well (χ2/df = 1.532, root mean square error of approximation = 0.042, goodness of fit = 0.900, incremental fit index = 0.949, comparative fit index = 0.948, Tucker–Lewis index = 0.940). The total Cronbach’s α was 0.862, the total McDonald’s ω was 0.869, and the test-retest reliability coefficient was 0.856. Results of convergent validity (average variance extracted = 0.486–0.722) and discriminant validity provided good or acceptable psychometric support. Significant correlations between scores of the C-PoDLiS and Mental health literacy scale (r = 0.155–0.581, p < 0.01) and Attitudes toward seeking professional psychological help short form scale (r = 0.361–0.432, p < 0.01) supported good concurrent and predictive validity, respectively. No floor/ceiling effect was found. Conclusion The C-PoDLiS was demonstrated to be a sound instrument with good reliability and validity for evaluating Chinese perinatal women’s PoDLi levels. Its use in the future can facilitate data aggregation and outcome comparisons across different studies on this topic.

Abstract
INTRODUCTION Gestational diabetes mellitus (GDM) is one of the most prevalent diseases during pregnancy, which is closely associated with many short-term and long-term maternal and neonatal complications and can incur heavy financial burden on both families and society. Web-based interventions have been used to manage GDM because of the advantages of high accessibility and flexibility, but their effectiveness has remained inconclusive. This systematic review and meta-analysis aims to comprehensively investigate the multidimensional effectiveness of web-based interventions for pregnant women with GDM, thereby aiding implementation decisions in clinical settings. METHODS AND ANALYSIS This systematic review protocol strictly adheres to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines. Six electronic databases (PubMed, Web of Science, Cochrane Central Register of Controlled Trials, Embase, CINAHL and PsycINFO) will be comprehensively searched from their inception to 26 January 2022 to identify randomised controlled trials and controlled clinical trials regarding the efficacy of web-based interventions for pregnant women with GDM on glycaemic control, behavioural outcomes, cognitive and attitudinal outcomes, mental health, maternal and neonatal clinical outcomes, and medical service utilisation and costs. Two reviewers will independently conduct the study selection, data extraction and quality assessment. The methodological quality of included studies will be assessed using the Effective Public Health Practice Project assessment tool. The overall meta-analyses for each of the interested outcomes will be performed if the outcome data are sufficient and provides similar effect measures, as well as subgroup analyses for glycaemic control indicators based on the different types of intervention format, interactivity and technology. We will conduct a qualitative synthesis for studies that cannot be quantitatively synthesised. ETHICS AND DISSEMINATION Ethics approval is not required for this review as no human participants will be involved. The results will be disseminated via a peer-reviewed journal or an academic conference. PROSPERO REGISTRATION NUMBER CRD42022296625.

Abstract
Reticuloendotheliosis virus (REV) is an avian oncogenic retrovirus that causes atrophy of immune organs, such as the spleen, thymus, and bursa of Fabricius, leading to severe immunosuppression. However, there is limited information describing the genes or microRNAs (miRNAs) that play a role in replicating REV-spleen necrosis virus (SNV). Our previous miRNA and RNA sequencing data showed that the expression of gga-miR-222b-5p was significantly upregulated in REV-SNV-infected chicken spleens of 7, 14, and 21 dpi compared to non-infected chicken spleens, but mitogen-activated protein kinase 10 (MAPK10), which is related to innate immunity, had the opposite expression pattern. To understand chicken cellular miRNA function in the virus-host interactions during REV infection, we used quantitative reverse transcription PCR (qRT-PCR) to determine whether the expression of gga-miR-222b-5p and MAPK10 in the spleen of specific-pathogen-free chickens at 28, 35, and 42 dpi was consistent with the first 3 time points, and dual-luciferase reporter assay was used to determine the targeting relationship between gga-miR-222b-5p and MAPK10. Results show that MAPK10 was downregulated at all 3 time points; however, significant difference (p⟨0.01) was noted only at 35 dpi. Moreover, the expression of gga-miR-222b-5p was upregulated; however, significant difference (p⟨0.01) was observed only at 28 and 35 dpi. A dual-luciferase reporter assay showed that MAPK10 is a direct target of gga-miR-222b-5p. This study suggests that gga-miR-222b-5p may target MAPK10 to promote the REV-SNV-induced tumorigenesis via the RLRs signaling pathway.

Abstract
OBJECTIVE Gastric cancer is a common malignancy, with high metastasis and poor prognosis. Our purpose was to explore potential molecular mechanisms of gastric cancer. PATIENTS AND METHODS A total of 10 pairs of gastric cancer tissues and adjacent normal gastric tissues were collected for RNA sequencing (RNA-seq), followed by differential expression analysis. Combining qRT-PCR results, two novel genes were selected for in-depth analysis, including up-regulated ONECUT and down-regulated SST. To investigate the effects of ONECUT and SST on the biological behaviors of gastric cancer cells, gastric cancer cell lines were transfected by ONECUT2 knockdown and SST overexpression. Afterwards, cell migration and invasion were examined using transwell assays, and the expressions of epithelial-mesenchymal transition (EMT)-related proteins were measured by Western blot analysis. Furthermore, cell viability was detected by CCK-8 assay. Finally, tumorigenicity in nude mice was performed. RESULTS Gastric cancer cell migration and invasion were inhibited in BGC823 cells transfected by shONECUT2. Similar results were observed in SST overexpression in MGC803 cells. Silencing ONECUT2 or overexpressing SST reduced the expressions of mesenchymal markers (N-cadherin and vimentin), STAT3, fibronectin, Wnt2, β-catenin and increased epithelial marker (E-cadherin), p-STAT3, smad2/3, α-catenin protein levels. In addition, inhibiting ONECUT2 or elevated SST suppressed tumor cell viability in vitro. Moreover, ONECUT2 silencing or elevated SST significantly inhibited tumor growth in vivo. CONCLUSIONS Up-regulated ONECUT2 and down-regulated SST promote gastric cell migration, invasion, epithelial-mesenchymal transition and tumor growth in gastric cancer.

Abstract
OBJECTIVE To analyze the species, abundance and structure differences of intestinal flora between patients with type 2 diabetes mellitus (T2D) and healthy individuals and explore the correlation between intestinal flora changes and T2D. OBJECTIVE We collected a total of 133 clinical fecal samples from 78 healthy individuals and 55 patients with T2D. Hiseq2500 was used for high-throughput sequencing of the V3+V4 regions of the 16S rRNA gene. Usearch and QIIME were used for data splicing and filtering, classification and species annotation. The Alpha diversity index and Beta diversity index of the samples were analyzed using R language data packets to compare the richness and diversity of the sample flora. The flora differences were compared between the two groups and the disease marker flora was screened after correction of the relevant factors. PICRUST software was used to predict the function of different flora. OBJECTIVE There was significant difference in the intestinal flora diversity between the two groups. Cluster analysis showed that Fimicutes and Bacteroidetes were the dominant species at the phylum level. LefSe analysis showed that significant differences in the relative abundance between the two groups in 2 phyla, 3 classes, 3 orders, 4 families and 10 genera. After correction for the influence of related factors, the markers of T2Drelated bacteria groups were identified, including Bifidobacterium, Bifidobacteriales, Bifidobacteriaceae, Actinobacteria, Bacilli, Lactobacillales, Lactobacillaceae and Lactobacillus. On this basis, analysis of KEGG metabolic pathways of the differential flora revealed significant differences in 36 KEGG metabolic pathways between the two groups, and the citric acid cycle, lipopolysaccharide biosynthesis and other metabolic pathways were all up-regulated in T2D group. OBJECTIVE The composition and abundance of intestinal flora were different between T2D group and the normal group, and T2D group showed the characteristics of ecological imbalance.

Abstract
OBJECTIVE To explore the underlying mechanism of ncRNA (MIR22HG) in thyroid papillary carcinomas. PATIENTS AND METHODS 40 pairs of thyroid papillary carcinomas tissues and adjacent normal tissues were collected from patients of the First Affiliated Hospital of Guangxi Medical University, who underwent oral surgery. qRT-PCR was applied to detect the expression of MIR22HG, miR-24-3p and p27kip1 in tissues and cells. Western blot was used to measure the protein level of p27kip1 in tissues and cells. Kaplan-Meier plot was used to analyze the overall survival rates in thyroid papillary carcinomas. Pearson's correlation analysis was used to analyze the correlation relationship among MIR22HG, miR-24-3p and p27kip1 expression. Flow cytometric assay was applied to measure cell apoptosis. Transwell assay was used to assess cell migration and invasion abilities. Luciferase reporter assay was applied to verify the molecular relationships among MIR22HG, miR-24-3p and p27kip1 in thyroid papillary carcinomas. RESULTS LncRNA MIR22HG and p27kip expressed low while miR-24-3p expressed high in thyroid papillary carcinomas and cells. Overexpression of MIR22HG inhibited cell proliferation, migration and invasion, whereas promoted cell apoptosis in thyroid papillary carcinomas cells. However, these effects were reversed by upregulation of miR-24-3p. Further exploration showed that the promoted effects of miR-24-3p mimics on thyroid papillary carcinomas cells were suppressed by enhancing p27kip1 expression. Meanwhile, MIR22HG induced p27kip1 expression by binding miR-24-3p in thyroid papillary carcinomas. CONCLUSIONS MIR22HG inhibited cell growth through modulating p27kip1 by decreasing miR-24-3p expression in thyroid papillary carcinomas, providing a new modulate mechanism and therapeutic targets in thyroid papillary carcinomas.

Abstract
Streptococcus mutans is a major cariogenic pathogen that resides in multispecies oral microbial biofilms. The VicRK 2-component system is crucial for bacterial adaptation, virulence, and biofilm organization and contains a global and vital response regulator, VicR. Notably, we identified an antisense vicR RNA (AS vicR) associated with an adjacent RNase III–encoding ( rnc) gene that was relevant to microRNA-size small RNAs (msRNAs). Here, we report that ASvicR overexpression significantly impeded bacterial growth, biofilm exopolysaccharide synthesis, and cariogenicity in vivo. Transcriptome analysis revealed that the AS vicR RNA mainly regulated carbohydrate metabolism. In particular, overproducing AS vicR demonstrated a reduction in galactose and glucose metabolism by monosaccharide composition analysis. The results of high-performance gel permeation chromatography revealed that the water-insoluble glucans isolated from AS vicR presented much lower molecular weights. Furthermore, direct evidence showed that total RNAs were disrupted by rnc-encoded RNase III. With the coexpression of T4 RNA ligase, putative msRNA1657, which is an rnc-related messenger RNA, was verified to bind to the 5′-UTR regions of the vicR gene. Furthermore, AS vicR regulation revealed a sponge regulatory-mediated network for msRNA associated with adjacent RNase III–encoding genes. There was an increase in AS vicR transcript levels in clinical S. mutans strains from caries-free children, while the expression of AS vicR was decreased in early childhood caries patients; this outcome may be explored as a potential strategy contributing to the management of dental caries. Taken together, our findings suggest an important role of AS vicR-mediated sponge regulation in S. mutans, indicating the characterization of lactose metabolism by a vital response regulator in cariogenicity. These findings have a number of implications and have reshaped our understanding of bacterial gene regulation from its transcriptional conception to the key roles of regulatory RNAs.

Abstract
The oral cavity contains a distinct habitat that supports diverse bacterial flora. Recent observations have provided additional evidence that sRNAs are key regulators of bacterial physiology and pathogenesis. These sRNAs have been divided into 5 functional groups: cis-encoded RNAs, trans-encoded RNAs, RNA regulators of protein activity, bacterial CRISPR (clustered regularly interspaced short palindromic repeat) RNAs, and a novel category of miRNA-size small RNAs (msRNAs). In this review, we discuss a critical group of key commensal and opportunistic oral pathogens. In general, supragingival bacterial sRNAs function synergistically to fine-tune the regulation of cellular processes and stress responses in adaptation to environmental changes. Particularly in the cariogenic bacteria Streptococcus mutans, both the antisense vicR RNA and msRNA1657 can impede the metabolism of bacterial exopolysaccharides, prevent biofilm formation, and suppress its cariogenicity. In Enterococcus faecalis, selected sRNAs control the expression of proteins involved in diverse cellular processes and stress responses. In subgingival plaques, sRNAs from periodontal pathogens can function as novel bacterial signaling molecules that mediate bacterial-human interactions in periodontal homeostasis. In Porphyromonas gingivalis, the expression profiles of putative sRNA101 and sRNA42 were found to respond to hemin availability after hemin starvation. Regarding Aggregatibacter actinomycetemcomitans (previously Actinobacillus actinomycetemcomitans), a major periodontal pathogen associated with aggressive periodontitis, the predicted sRNAs interact with several virulence genes, including those encoding leukotoxin and cytolethal distending toxin. Furthermore, in clinical isolates, these associated RNAs could be explored not only as potential biomarkers for oral disease monitoring but also as alternative types of regulators for drug design. Thus, this emerging subspecialty of bacterial regulatory RNAs could reshape our understanding of bacterial gene regulation from their key roles of endogenous regulatory RNAs to their activities in pathologic processes.

Abstract
To investigate the expression of microRNA-34a (miR-34a) in patients with chronic lymphocytic leukemia (CLL) in Xinjiang Uygur and Han nationalities and its prognostic significance. Our data showed that miR-34a expression in Uygur and Han CLL patients was significantly higher than that in their respective healthy controls, while miR-34a levels were similar between Uygur and Han patients. By comparing with known prognostic factors, receiver operating characteristic (ROC) curves showed that miR-34a was a good predictive factor for the prognosis of CLL (demarcation value was 3.567 6). Survival analysis was further performed according to miR-34a expression level, that low expression of miR-34a translated into poor prognosis.

Abstract
OBJECTIVE This study aimed to investigate the prevalence of general anxiety disorder (GAD) among postmenopausal women with symptomatic pelvic organ prolapse (POP) and to identify its associated factors. METHODS A cross-sectional study was conducted among postmenopausal women with symptomatic POP. Sociodemographic data and medical histories were obtained. Participants completed the POP Quantification (POP-Q), the Pelvic Floor Impact Questionnaire-7 (PFIQ-7), and the Pelvic Floor Distress Inventory (PFDI-20) measures. Measures of GAD were obtained using the Generalized Anxiety Disorder-7 (GAD-7). The data were analyzed using independent sample t-tests, the Mann-Whitney U-test, χ2 tests, Fisher's exact tests and logistic regression. RESULTS Of the 177 participants interviewed, 19.2% had symptoms of GAD. There were no statistically significant differences in the sociodemographic characteristics or the POP-Q stage between women with and without GAD (p > 0.05). GAD was significantly associated with higher PFDI-20 and PFIQ-7 subscale scores (p < 0.05). After multiple logistic regression analyses, only the PFIQ-7 subscale UIQ-7 (odds ratio = 1.025, 95% confidence interval 1.007-1.043, p = 0.005) and the PFDI-20 subscale CRADI-8 (odds ratio = 1.025, 95% confidence interval 1.004-1.047, p = 0.021), which represented the impact on quality of life from lower urinary tract symptoms and the distress caused by bowel dysfunction, were risk factors that were independently associated with GAD. CONCLUSIONS GAD is prevalent in almost one-fifth of postmenopausal women with symptomatic POP. GAD is not associated with the severity of the POP-Q stage but is associated with higher scores for lower urinary tract and bowel dysfunction caused by POP.

Abstract
BACKGROUND While next generation sequencing has enhanced our understanding of the biological basis of malignancy, current knowledge on global practices for sequencing cancer samples is limited. To address this deficiency, we developed a survey to provide a snapshot of current sequencing activities globally, identify barriers to data sharing and use this information to develop sustainable solutions for the cancer research community. METHODS A multi-item survey was conducted assessing demographics, clinical data collection, genomic platforms, privacy/ethics concerns, funding sources and data sharing barriers for sequencing initiatives globally. Additionally, respondents were asked as to provide the primary intent of their initiative (clinical diagnostic, research or combination). RESULTS Of 107 initiatives invited to participate, 59 responded (response rate = 55%). Whole exome sequencing (P = 0.03) and whole genome sequencing (P = 0.01) were utilized less frequently in clinical diagnostic than in research initiatives. Procedures to identify cancer-specific variants were heterogeneous, with bioinformatics pipelines employing different mutation calling/variant annotation algorithms. Measurement of treatment efficacy varied amongst initiatives, with time on treatment (57%) and RECIST (53%) being the most common; however, other parameters were also employed. Whilst 72% of initiatives indicated data sharing, its scope varied, with a number of restrictions in place (e.g. transfer of raw data). The largest perceived barriers to data harmonization were the lack of financial support (P < 0.01) and bioinformatics concerns (e.g. lack of interoperability) (P = 0.02). Capturing clinical data was more likely to be perceived as a barrier to data sharing by larger initiatives than by smaller initiatives (P = 0.01). CONCLUSIONS These results identify the main barriers, as perceived by the cancer sequencing community, to effective sharing of cancer genomic and clinical data. They highlight the need for greater harmonization of technical, ethical and data capture processes in cancer sample sequencing worldwide, in order to support effective and responsible data sharing for the benefit of patients.

Abstract
Sogatella furcifera Horváth (Hemiptera: Delphacidae), is a major migratory pest of rice crops in Asia. The ultrastructure of the flight muscle directly affects the flight ability of insects. The ultrastructure of the flight muscle of some insects can be affected by insecticides. However, the ultrastructure of the flight muscle of S. furcifera and the effect of insecticides on the flight muscle of S. furcifera are not well understood. The present study was conducted to determine the effect of the insecticide dinotefuran on the ultrastructure of the flight muscle of S. furcifera females. In this study, the cross-sectional area and the diameter of the myofibril cross-sections of dinotefuran-treated S. furcifera females increased with the number of days after emergence (DAE), and they were higher than in untreated females. The sarcomere length of myofibrils increased with the number of DAE, and it differed from that of the untreated females. On the first day after emergence, the higher the concentration of dinotefuran, the smaller was the extent of decrease. On the third day after emergence, the higher the concentration of dinotefuran, the larger was the extent of enhancement. For the percentage of mitochondria, those of LC10 and LC20 dinotefuran-treated S. furcifera females increased with the number of DAE and were higher than in untreated females. LC10 dinotefuran-treated S. furcifera females exhibited the largest increase. Thus, our results suggest that the flight ability of S. furcifera increased with time. Some concentrations of dinotefuran can enhance the flight capacity of S. furcifera.

Abstract
Objective:To investigate the differences of volume of pharyngeal cavity between normal healthy subjects and patients with severe obstructive sleep apnea hypopnea syndrome(OSAHS)before and after surgery and its application value in assessment of surgical curative effect.Method:Forty-four healthy male adults were included in normal group.Thirty-eight patients with severe OSAHS diagnosed by polysomnography were included in experimental group(OSAHS group). Volume of pharyngeal cavity, oropharynx and laryngopharynx measured by acoustic pharyngealmetry and AHI, obstructive apnea frequency and the lowest oxygen saturation recorded by PSG monitor were all obtained in normal groups and experimental groups before and 3 months after the surgery. All the data are statistically analyzed. Result:Volume of pharyngeal cavity,AHI,obstructive apnea frequency and lowest oxygen saturation of patients in experimental group were all improved after surgery compared with pre-operation(P<0.01). Conclusion: The measurement of pharyngeal cavity volume is helpful to the quantitative analysis of upper airway structure and determine the stenosis location, it is also useful to guide surgery and evaluate the curative effect of the surgery.

Abstract
BACKGROUND Limited research has been published on current Helicobacter pylori infection rate in asymptomatic children in China. AIM To assess current Helicobacter pylori infection rate, distribution characteristics and risk factors in Chinese asymptomatic children. METHODS A prospective, cross-sectional, population-based study was performed from 2009 to 2011 in three cities of China. Helicobacter pylori infection was diagnosed by a stool antigen test. Multi-stage cluster random sampling was used to select asymptomatic children including neonates. Socioeconomic details were obtained through a standardised questionnaire. RESULTS Among total of 3491 children (0-18 years), the global infection rate was 6.8% and there were no significant differences between genders. Age specific infection rate between regions was significantly different (P < 0.05). The infection rate significantly increased with age (P for trend <0.01). It was low during the newborn (0.6%) to preschool period and was significantly increased in high school students (13.5%) (P < 0.01). Multivariable regression indicated that hand sanitisation, individually served meals, higher education level of mother, above average living space and residence in urban areas were significantly protective against infection (OR 0.749, 0.698, 0.720, 0.838 and 0.770 respectively). Conversely, consuming meals in unsanitised conditions, sharing towels, receiving pre-chewed food from the mother, artificial feeding and family history of gastrointestinal disease were significantly associated with the risk of infection (OR 1.200, 1.965, 2.002, 1.071 and 2.093 respectively). CONCLUSIONS Helicobacter pylori infection rate increases with age in Chinese asymptomatic children and is common after 10 years of age. The rate of infection is related to socioeconomic status.

Abstract
We evaluated the relationship between total serum immunoglobulin E (IgE) levels and pregnancy outcome in a prospective cohort study focusing on fetal growth restriction (FGR). Sixty women with FGR and twenty with normal singleton pregnancy were enrolled during their third trimester. Infants were followed up for 6 months. Blood samples were obtained from pregnant women during the third trimester; cord blood samples were also taken. Six months after birth, blood samples were obtained from infants. Demographic and baseline characteristics were compared between groups. Birth weight, length and head circumference of neonates in the FGR group were lower than those in the control group. Total serum IgE level was significantly increased in third-trimester pregnant women with FGR compared with normal group (P < 0.05). However, this trend was not observed in the cord blood at birth or peripheral blood of 6-month-old infants. The prevalence of atopic eczema between the 2 groups was similar. Linear regression analysis revealed that the IgE level in the third trimester was negatively correlated with birth weight (P < 0.05). Higher serum IgE level in the cord blood was significantly associated with an increased risk of being small for gestational age (P < 0.05). In conclusion, IgE levels in the third trimester of pregnancy and cord blood are strongly related to birth outcomes of FGR.

Abstract
The aim of this study was to separate, purify, and identify Salmonella paratyphi A flagellin, and to prepare its antisera. Primary flagellin was isolated from S. paratyphi A using the acid lysis method. The flagellin was purified with weak anion exchange chromatography and the protein was identified with sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), Western blot, and negative staining with phosphotungstic acid with scanning electron microscopy (SEM). The production of the obtained flagellin was then quantified. New Zealand white rabbits were then immunized with the isolated flagellin, the presence of serum anti-flagellin antibodies was assessed with the immunoblot test, and its potency was determined with the double immunodiffusion test. The results of SDS-PAGE showed that the molecular weight (m.w.) of the purified flagellin was 52 x 10(3). The immunoblot test also showed a band at 52 x 10(3) m.w. The SEM results showed that the flagellin was filamentous. These three results showed that the protein was homogeneous. The protein quantification analysis found that 4.8 ± 0.5 mg flagellin could be extracted per 1 g wet weight bacteria. The titer of the anti-flagellin antiserum was 1:64. Through this method, we obtained high productions of flagellin, which could be easily purified, identified, and prepared into high titer antiserum.

Abstract
Electrically generated flows around a thin dielectric plate pierced by a cylindrical hole are computed numerically. The geometry represents that of a single nanopore in a membrane. When the membrane is uncharged, flow is due solely to induced charge electroosmosis, and eddies are generated by the high fields at the corners of the nanopore. These eddies meet at stagnation points. If the geometry is chosen correctly, the stagnation points merge to form a single stagnation point at which four streamlines cross at a point and eight eddies meet.

Abstract
A theoretical model of electroosmosis through a circular pore of radius a that traverses a membrane of thickness h is investigated. Both the cylindrical surface of the pore and the outer surfaces of the membrane are charged. When h ≫ a, end effects are negligible, and the results of full numerical computations of electroosmosis in an infinite pore agree with theory. When h = 0, end effects dominate, and computations again agree with analysis. For intermediate values of h/a, an approximate analysis that combines these two limiting cases captures the main features of computational results when the Debye length κ(-1) is small compared with the pore radius a. However, the approximate analysis fails when κ(-1) ≫ a, when the charge cloud due to the charged cylindrical walls of the pore spills out of the ends of the pore, and the electroosmotic flow is reduced. When this spilling out is included in the analysis, agreement with computation is restored.
