Highlights Curving 2D MXene into 1D nanofibers can effectively stop the restacking of MXene flakes, and then the nanofibers are used to construct a lightweight and multifunctional MXene/C aerogel. The MXene/C aerogels achieved an RLmin of − 53.02 dB and EAB of 5.3 GHz. The radar cross-sectional reduction value of MXene/C aerogels can reach 12.02 dB m2. Integrating multiple functions such as thermal insulation, sensing, and microwave absorption into one material—MXene/C aerogel.

Abstract Background Metabolic syndrome (MetS) has been related to the pathogenesis of variety categories of cancers. This meta-analysis aimed to determine the association between MetS and the incidence of lung cancer. Methods Relevant cohort studies were identified by search of PubMed, Embase, and Cochrane’s Library databases. Cochrane’s Q test and I2 statistic were used to analyze the heterogeneity. Random-effect model which incorporates the potential heterogeneity was used for the meta-analysis. Results Five cohort studies with 188,970 participants were included. A total of 1,295 lung cancer cases occurred during follow-up. Meta-analyses showed that neither MetS defined by the revised NCEP-ATP III criteria (hazard ratio [HR]: 0.94, 95% confidence interval [CI]: 0.84 to 1.05, p = 0.25; I2 = 0) nor the IDF criteria (HR: 0.82, 95% CI: 0.61 to 1.11, p = 0.20; I2 = 0) was associated with an affected risk of lung cancer. Subgroup analyses showed consistent results in women and in men, in studies performed in Asian and non-Asian countries, and in prospective and retrospective cohorts (p all > 0.05). Meta-analysis limited to studies with the adjustment of smoking status also showed similar results (HR: 0.91, 95% CI: 0.80 to 1.05, p = 0.21; I2 = 0). No publication bias was detected based on the Egger regression test (p = 0.32). Conclusions Current evidence from cohort studies does not support that MetS is an independent risk factor for the incidence of lung cancer.

Silica aerogels are one of the most widely used aerogels, exhibiting excellent thermal insulation performance and ultralow density. However, owing to their plenitude of Si-O-Si bonds, they possess high infrared emissivity in the range of 8–13 µm and are potentially robust passive radiative cooling (PRC) materials. In this study, the PRC behavior of traditional silica aerogels prepared from methyltrimethoxysilane (MTMS) and dimethyldimethoxysilane (DMDMS) in outdoor environments was investigated. The silica aerogels possessed low thermal conductivity of 0.035 W/m·K and showed excellent thermal insulation performance in room environments. However, sub-ambient cooling of 12 °C was observed on a clear night and sub-ambient cooling of up to 7.5 °C was achieved in the daytime, which indicated that in these cases the silica aerogel became a robust cooling material rather than a thermal insulator owing to its high IR emissivity of 0.932 and high solar reflectance of 0.924. In summary, this study shows the PRC performance of silica aerogels, and the findings guide the utilization of silica aerogels by considering their application environments for achieving optimal thermal management behavior.

Background: Statin, a lipid-lowering drug, has been suggested to confer anticancer efficacy. However, previous studies evaluating the association between statin use and prognosis in breast cancer showed inconsistent results. A meta-analysis was performed to evaluate the association between statin use and clinical outcome in women with breast cancer.Methods: Cohort studies comparing recurrence or disease-specific mortality in women with breast cancer with and without using of statins were identified by search of PubMed, Embase, and Cochrane's Library databases. A random-effect model, incorporating the inter-study heterogeneity, was used to combine the results. Subgroup analyses were performed to evaluate the influences of study characteristics on the outcomesResults: Seventeen cohort studies with 168,700 women with breast cancer were included. Pooled results showed that statin use was significantly associated with a lower risk of breast cancer recurrence (adjusted hazard ratio [HR] = 0.72, p < 0.001) and breast cancer mortality (HR = 0.80, p < 0.001). Subgroup analysis showed that timing of statin use, statin type, study design, sample size, or quality score did not significantly affect the outcomes. However, statin use was associated with more remarkably reduced breast cancer recurrence in studies with mean follow-up duration ≤ 5 years (HR = 0.55, p < 0.001) than that in studies of >5 years (HR = 0.83, p = 0.01).Conclusions: Statin use is associated with reduced recurrence and disease-specific mortality in women with breast cancer. These results should be validated in randomized controlled trials.

Abstract Background Investigations on the role of the time-mean serum uric acid (SUA) value in determining the risk of chronic kidney disease (CKD) are limited. We investigated whether the time-mean SUA value indicates the risk of CKD, and explored associations of the baseline and time-mean SUA levels with kidney function decline and incident CKD in a healthy population. Methods We initiated an inhabitant-based cohort study between January 2011 and December 2016. All participants completed a yearly medical check-up at the Zhejiang Province People’s Hospital and had baseline estimated glomerular filtration rates (eGFR) > 60 ml/min/1.73m2. The SUA level and eGFR were assessed every year in the follow-up period. A multivariate adjusted binary logistic regression analysis and Cox proportional hazards models were used to evaluate the risk of newly-developed CKD among different stratified groups. Results During the 6-year follow-up period, 227 (4.4%) participants developed CKD. In multivariable-adjusted analyses, the odds ratio (OR) for new-onset CKD increased, with higher time-mean SUA levels than at baseline (OR: 1.00 [reference], 2.709 [95% confidence interval: 1.836–5.293], 3.754 [1.898–7.428], and 7.462 [3.694–15.073]). After adjustment for potential cofounders, a multivariate Cox proportional hazard model showed that a higher SUA increased the risk of developing CKD (the adjusted hazard ratios of the highest and lowest quartiles for the baseline and time-mean SUA levels were 1.689 [1.058–2.696] and 6.320 [3.285–12.159], respectively). Conclusion An increased time-mean and single SUA value were independently associated with an increased likelihood of eGFR decline and development of new-onset CKD in the general population.

Abstract Background To describe the indications, techniques and preliminary experience of modified spiral tracheoplasty in the reconstruction of large tracheal defect after thyroidectomy. Methods The medical records of patients who underwent tracheal torsion to repair large tracheal defects after thyroid carcinoma surgery from January 2019 to January 2022 were retrospectively reviewed. The extent of tracheal defect, duration of tracheal reconstruction, postoperative complications and surgery results were analyzed. Results The duration of tracheal reconstruction was 30–60 min. No postoperative bleeding, incision infection, tracheostomy stenosis occurred. Recurrent laryngeal nerve palsy occurred in 5 patients. All patients were followed up for 24 to 60 months. The 2-year overall survival rate was 100%, the 2-year local control rate of trachea was 100%, and the 2-year tumor-free survival rate was 81.8%. Conclusion The modified spiral tracheoplasty is a safe and effective method to repair the large defect of trachea after thyroid carcinoma invading the trachea.

Abstract Manganese (Mn) is widely recognized owing to its low cost, non-toxic nature, and versatile oxidation states, leading to the emergence of various Mn-based nanomaterials with applications across diverse fields, particularly in tumor diagnosis and therapy. Systematic reviews specifically addressing the tumor diagnosis and therapy aspects of Mn-derived biomaterials are lacking. This review comprehensively explores the physicochemical characteristics and synthesis methods of Mn-derived biomaterials, emphasizing their role in tumor diagnostics, including magnetic resonance imaging, photoacoustic and photothermal imaging, ultrasound imaging, multimodal imaging, and biodetection. Moreover, the advantages of Mn-based materials in tumor treatment applications are discussed, including drug delivery, tumor microenvironment regulation, synergistic photothermal, photodynamic, and chemodynamic therapies, tumor immunotherapy, and imaging-guided therapy. The review concludes by providing insights into the current landscape and future directions for Mn-driven advancements in the field, serving as a comprehensive resource for researchers and clinicians.

BackgroundMetabolic syndrome (MS) is a significant risk factor for cardiovascular and cerebrovascular diseases, primarily driven by insulin resistance (IR). Although the herbal compound Chaihu Shugan powder (CSP) has demonstrated the potential to improve IR in animal models of MS, its mechanism of action remains incompletely understood. Therefore, this study aimed to investigate the biological pathways through which CSP exerts its therapeutic effects on IR in MS using both in vitro and in vivo methods.MethodsThe primary metabolites of CSP aqueous extract and CSP-containing serum were measured by LC-MS/MS. A mouse model of MS-related IR was induced by a high-fat, high-fructose diet combined with chronic immobilization stress. The CSP’s therapeutic potential was evaluated through glucose and insulin tolerance tests and hepatic insulin signaling molecules (p-IRS-1, IRS-1, p-Akt, and Akt). The expression of lipid metabolism-related factors (FFA, DAG, LXRα, SREBP-1, FASN, and ACC) in the liver was also measured. Hepatocyte IR was modeled using high-glucose and high-insulin conditions, and CSP impact was evaluated using 2-NBDG uptake and insulin signaling molecule expression. The specific mechanism of CSP was explored using the LXRα agonist T0901317.ResultsThe MS-related IR model exhibited a decreased p-Akt/Akt ratio and increased fasting glucose, insulin, homeostatic model assessment of IR, and hepatic lipid metabolism factors. Treatment with CSP mitigated these effects. In the hepatocyte IR model, CSP-containing serum improved glucose uptake and modulated the expression of insulin signaling and lipid metabolism factors. Furthermore, T0901317 reversed the beneficial effects of CSP, indicating the role of LXRα in CSP’s therapeutic action.ConclusionThe CSP ameliorated IR in MS by restoring fatty acid metabolism through the regulation of the LXRα/SREBP-1 signaling pathway.

Aims: To systematically evaluate the efficacy and safety of the Guanxinshutong capsule (GXST) combined with Western medicine (WM) in treating stable angina pectoris (SAP).Methods: Randomized controlled trials (RCTs) evaluating the efficacy of GXST combined with WM for the treatment of patients with SAP were searched across several databases, including the Cochrane Library, PubMed, Embase, the Chinese National Knowledge Infrastructure (CNKI), the Chinese Science and Technology Journal Database (VIP), and Wan Fang, from inception until 30 April 2024. Two independent reviewers rigorously performed study selection, data extraction, and quality assessment. Version 2 of the Cochrane risk-of-bias tool for randomized trials (RoB 2) was employed to assess the methodological quality of included RCTs. R version 4.2.2 was applied for data synthesis.Results: Between 2012 and 2024, 31 RCTs involving 4,172 patients were identified, with 2,101 in the experimental group and 2,071 in the control group. GXST and WM combination was significantly more effective than WM alone across several metrics: clinical efficacy rate (odds ratio [OR] = 4.05, 95% confidence interval [CI] = 3.42–4.80), electrocardiogram improvement (OR = 3.39, 95% CI = 2.35–4.87), enhancement in left ventricular ejection fraction (mean difference [MD] = 1.07, 95% CI = 0.69–1.46), reduction in total cholesterol levels (MD = −0.78, 95% CI = −1.20 to −0.35), decrease in tumor necrosis factor-alpha (MD = −1.36, 95% CI = −2.18 to −0.53), and improvement in Chinese medicine evidence score (OR = 3.77, 95% CI = 2.20–6.43). No significant difference was observed in the reduction in C-reactive protein levels (MD = −6.66, 95% CI = −15.91 to 2.59), triglyceride levels (MD = −1.62, 95% CI = −3.39 to 0.15), or in the occurrence of adverse drug reactions (OR = 0.60, 95% CI = 0.23–1.57). Based on meta-regression and subgroup analyses, the observed heterogeneity was attributed to variations in GXST capsule dosage, the duration of treatment, and the baseline characteristics of patients.Conclusion: GXST and WM combination therapy demonstrates the potential to enhance clinical outcomes for SAP patients. Nevertheless, additional rigorous studies are imperative to substantiate the reliability and safety of this combined treatment modality.Systematic Review Registration: The protocols for this meta-analysis were registered in the International Prospective Register of Systematic Reviews (PROSPERO, https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=543537, Identifier CRD42024543537).

PurposeSleep disturbances are prevalent in autistic children. The emergence of telehealth offers new possibilities for remote professional intervention. By combining telehealth with parental support, this study aims to explore a novel family-based model to enhance moderate-to-vigorous physical activity (MVPA) and improve sleep quality in children with autism.MethodsThirty-four autistic children (mean age = 15.7 years) were randomly assigned to either a 6-month intervention group or a control group. Both groups received standard physical education classes at school. The intervention group received additional after-school telehealth support. MVPA and sleep quality were assessed 1 week before the intervention and at the 6-month follow-up.ResultsAfter 6 months, children in the intervention group nearly doubled their daily MVPA compared to the control group (Cohen's d = 8.34, CI95% = 6.17–10.52). Actigraphy-assessed sleep efficiency was notably higher (d = 2.35, CI95% = 1.44–3.26), and there were reductions in wake time (d = 1.65, CI95% = 0.84–2.46), sleep fragmentation (d = 0.80, CI95% = 0.07–1.52), and sleep latency (d = 0.82, CI95% = 0.09–1.54) were all reduced. These improvements in objective sleep metrics were corroborated by subjective assessments using the Sleep Disturbance Scale for Children (d = 0.86, CI95% = 0.13–1.59).ConclusionsTelehealth combined with parental support addresses barriers to enhancing health behaviors at home. This innovative model not only improves after-school MVPA and sleep quality in autistic children but also holds significant potential for benefiting other populations requiring remote support.Clinical Trial Registrationhttps://clinicaltrials.gov/study/NCT06444659?id=NCT06444659&rank=1 (NCT06444659).

In this paper, we conducted a study of H-Toeplitz operators on the Dirichlet type space $ \mathfrak{D}_{t} $, which included several aspects. To begin, we established the matrix representation of the H-Toeplitz operator $ S_{\varphi} $ with respect to the orthonormal basis of $ \mathfrak{D}_t $. Subsequently, we characterized the compactness of $ S_{\varphi} $ in terms of the symbol $ \varphi $. Furthermore, we developed a new method to investigate the algebraic properties of H-Toeplitz operators, including self-adjointness, diagonality, co-isometry, partial isometry as well as commutativity.

Summary: Myocardial remodeling (MR) following myocardial infarction (MI) contributes to heart failure. Inflammation is a key determinant in cardiac remodeling, with potential prognostic improvements by inhibiting inflammatory factors. Pattern recognition receptors, including interferon gamma-inducible protein-16 (IFI-16), play significant roles in this process, yet its specific involvement remains underexplored. This study investigates IFI-16’s role in initiating inflammation via the inflammasome and its direct interaction with galectin-3 protein post-MI. Elevated IFI-16 levels were observed in human and rat myocytes and a mouse MI model under hypoxic, nutrient-deprived conditions, correlating with increased inflammation-associated proteins. Suppression of IFI-16/IFI-204 using short hairpin RNA (shRNA) lentivirus or adeno-associated virus decreased inflammatory factor activation, thereby mitigating remodeling and enhancing cardiac function post-MI. Co-immunoprecipitation (coIP) and double-fluorescence staining confirmed IFI-16’s ability to interact directly with galectin-3. These findings underscore IFI-16’s critical role as a pro-inflammatory factor in post-MI MR, suggesting its inhibition as a potential therapeutic strategy.

Background: Benign prostatic hyperplasia (BPH) is prevalent among the aging male population and often presents with distressing lower urinary tract symptoms. There is emerging evidence that commercial oral poly-herbal traditional Chinese medicine (TCM) formulation combined with Western medicine (WM) may offer enhanced therapeutic effects compared to WM alone in BPH treatment. Nevertheless, determining the optimal formulations for BPH remains controversial. We aimed to employ a network meta-analysis to compare and assess differences among commonly used and recommended poly-herbal TCM formulations outlined in the Chinese guidelines for BPH treatment, providing clinical medication recommendations and guidance.Methods: We extensively searched for RCTs of BPH patients that had oral poly-herbal TCM formulations and WM treatment, covering both English and Chinese databases up to 31 October 2023. The quality of the included studies was evaluated using the Cochrane risk-of-bias tool Version 2 (ROB2). A Bayesian network meta-analysis was performed to assess the effectiveness of various formulations, followed by sensitivity and subgroup analyses.Results: Our meta-analysis included 107 RCTs involving 11,037 patients across 16 oral poly-herbal TCM formulations. The quality of the selected studies was assessed as “Some concerns”. Most formulations combined with WM demonstrated superior therapeutic efficacy compared to WM alone. For clinical effective rate, Jingui Shenqi pill (JGSQ) + WM had the highest-ranking probability (87.38%). Concerning International Prostate Symptom Score (IPSS) and maximum flow rate of urine, Guizhi Fuling capsule (GZFL) + WM was most effective (91.10% and 98.55%). Regarding the quality of life score and postvoid residual urine, Pulean tablet (PLA) + WM ranked first (86.71% and 91.81%). In controlling prostate volume, Huange capsule (HE) + WM demonstrated the highest efficacy (95.65%). Additionally, among the interventions, Lingze (LZ) + WM capsule exhibited the lowest incidence of adverse drug reactions (2.32%).Conclusion: Combining oral poly-herbal TCM formulations with WM may provide greater therapeutic benefits in BPH treatment compared to WM alone. JGSQ, GZFL, PLA, and HE emerged as promising treatment options. However, further rigorous empirical studies are essential to substantiate these findings.Systematic Review Registration:https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=459651, CRD 42023459651.

The International Classification of Functioning, Disability, and Health (ICF) offers a comprehensive bio-psycho-social model for evaluating the multifaceted needs of individuals with disabilities. While its adoption in healthcare settings is widespread, its utilization within the domain of physical activity interventions, particularly for adolescents with intellectual disabilities (IDs), remains insufficiently explored. This study rigorously examines the efficacy of a 6-month ICF-based Adaptive Physical Activity (APA) intervention on the development of fundamental motor skills (FMSs), improvements in physical fitness (PF), and enhancements in quality of life (QoL) among adolescents with ID. A total of thirty-eight adolescents were randomly allocated into either an intervention group (IG), which participated in the tailored APA program, or a control group (CG), which received standard physical education. The findings demonstrated statistically significant improvements in the IG’s test of gross motor development (TGMD) total, locomotor, object control, and QOL scores relative to the CG (p < 0.001, η² = 0.330, 0.249, 0.224, and 0.439, respectively). Furthermore, substantial gains were observed in PF measures, including upper and lower limb strength as well as cardiorespiratory fitness (p < 0.001, η² = 0.254, 0.351, 0.176). Strong positive correlations were noted between FMS, PF, and QoL (r = 0.34–0.71, p < 0.05). This study underscores the importance of tailoring physical activity programs for adolescents with ID, offering insights into the relationships between FMS, PF, and QoL, and guidance for future interventions aimed at improving health outcomes in this population.

Aims:To systematically evaluate the comprehensive effect of combining Naoxintong capsule (NXT) with Western medicine (WM) on coronary heart disease post-percutaneous coronary intervention (PCI).Methods:Randomized controlled trials (RCTs) of NXT for patients with CHD after PCI were systematically searched across multiple databases, including the Cochrane Library, PubMed, Embase, Chinese National Knowledge Infrastructure (CNKI), Chinese Science and Technology Journal Database (VIP), and Wan Fang, from inception until 31 January 2023. Study selection, data extraction, and quality assessment were performed by two independent reviewers. The quality of the included studies was evaluated using version 2 of the Cochrane risk-of-bias tool (RoB 2), and data analysis was performed using R4.2.2.Results:Fifteen RCTs conducted between 2011 and 2022 and involving 1,551 patients were identified, with 774 and 777 patients in the experimental and control groups respectively. It was found that the NXT and WM combination was superior to the WM therapy alone in terms of the effective clinical rate (odds ratio [OR] = 4.69, 95% confidence interval [CI] = 2.13–10.30), effective rate in electrocardiogram (OR = 6.92, 95% CI = 3.44–13.92), effective rate in angina (OR = 5.90, 95% CI = 3.04–11.46), left ventricular ejection fraction (mean difference [MD] = 4.94, 95% CI = 2.89–6.99), brain natriuretic peptide (MD = −294.00, 95% CI = −584.60 to −3.39), creatine kinase-MB (MD = −7.82, 95% CI = −13.26 to −2.37), major adverse cardiovascular events (OR = 0.24, 95% CI = 0.14–0.43), maximum platelet aggregation rate (MD = −8.33, 95% CI = −11.64 to −5.01), and Chinese medicine evidence score (OR = 9.79, 95% CI = 3.57–26.85). However, there was no significant difference in cardiac troponin I level reduction (MD = −0.13, 95% CI = 0.35–0.09) or the occurrence of adverse medicine events (OR = 0.92, 95% CI = 0.41–2.05). Meta-regression and subgroup analyses indicated that NXT capsule dosage, treatment duration, and patient baseline characteristics contributed to the heterogeneity.Conclusion:A combination of NXT and WM can improve clinical outcomes in patients undergoing PCI. However, further studies are needed to confirm the reliability and safety of this combined treatment approach.Systematic Review Registration:PROSPERO, https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=369174, Identifier CRD42022369174.

ABSTRACT CONTEXT: Scrub typhus, caused by Orientia tsutsugamushi, has a wide range of clinical manifestations, including meningoencephalitis, acute renal failure, pneumonitis, myocarditis, and septic shock. However, there are no documented cases of scrub typhus with hypokalemia. In this report, we present a case of scrub typhus with hypokalemia and multiple organ failure syndrome, highlighting the importance of electrolyte imbalance in patients with scrub typhus. CASE REPORT: A 59-year-old woman presented to the emergency department with abdominal pain that had been present for 1 day. On admission, the physical examination and laboratory test results indicated that the patient had renal, liver, and circulatory failure, and hypokalemia. She developed meningitis and disseminated intravascular coagulation during hospitalization. She recovered with appropriate management, and was discharged on day 17. CONCLUSION: This report highlights the potential for atypical presentations of scrub typhus, including a previously undocumented association with hypokalemia. Although the contribution of hypokalemia to the patient’s clinical course remains uncertain, this case underscores the importance of considering electrolyte imbalance in the management of patients with scrub typhus. Further research is warranted to better understand the relationship between scrub typhus and electrolyte imbalance.

Objectives: We intended to preserve the internal branch of superior laryngeal nerve in transoral surgery of hypopharyngeal squamous cell carcinoma and observe swallowing function recovery. Methods: 26 patients with hypopharyngeal squamous cell carcinoma underwent transoral surgery with the preservation of internal branch of superior laryngeal nerve. Sensation in the pharyngolaryngeal mucosa was tested by flexible laryngoscope and swallow function was evaluated by water swallow test and MD Anderson Dysphagia Inventory questionnaire after surgery. Results: Surgeries were successfully performed in all patients. The internal branch of superior laryngeal nerve were preserved in all patients. Testing of mucosa sensation revealed the presence of the cough reflex in most patients. The water swallow test showed that 12 cases (46.15%) on the 1st day, 23 cases (88.46%) on the 7th day and 25 cases (96.15%) on the 14th day after operation had normal swallowing function. The mean score of MD Anderson Dysphagia Inventory was 98 on the 14th day after operation. All patients achieved an oral soft diet at a median of 3 days (range, 2–6 days), full normal oral diet at a median of 5.5 days (range, 4–10 days) and removal of the nasogastric tube at a median of 6 days (range, 5–11 days). During the two-year follow-up, 3 patients recured, 1 patient died of lung metastasis. Conclusions: Preserving of the internal branch of superior laryngeal nerve in transoral surgery is feasible, and it can help to achieve a satisfactory recovery of the swallowing function after surgery of hypopharyngeal squamous cell carcinoma.

This study evaluated the disparities in growth performance and nutritional composition between two common Chinese mitten crab varieties, “Jianghai 21” and “Changjiang 2”, cultured in Jiangxi Province. Over the breeding period, parameters such as body weight, height, carapace length and width, and lengths of the second and third legs exhibited increases. Growth indices of “Jianghai 21” surpassed those of “Changjiang 2” during the intermediate and late breeding phases. While “Changjiang 2” demonstrated significantly higher crude lipid content than “Jianghai 21”, the latter exhibited markedly higher levels of total amino acids (TAAs), essential amino acids (EAAs), and delectable amino acids. Although overall nutrient composition did not significantly differ, TAA and EAA contents in the hepatopancreas were notably greater in “Jianghai 21” than in “Changjiang 2”. Moreover, a total of 901 differentially expressed genes (DEGs) were identified between the two varieties, with 560 upregulated and 341 downregulated. These DEGs were primarily associated with pathways related to fatty acid degradation, metabolism, and growth regulation. The observed variances in growth performance and nutrient composition between “Jianghai 21” and “Changjiang 2” suggest potential regulation by relevant genes. In summary, the results showed that the growth performance of “Jianghai 21” is greater than that of “Changjiang 2”, offering valuable insights for the selection of aquaculture varieties in the region.

Abstract Background Advanced maternal age (AMA; ≥35 years) is considered to be a major risk factor for adverse pregnancy outcomes. Along with the global trend of delayed childbearing, and in particular, the implementation of China’s second and third-child policy leading to a dramatic increase of AMA in recent years, the association between maternal age and pregnancy outcomes requires more investigation. Methods A population-based retrospective study was performed. Data were derived from the Medical Birth Registry of Xiamen from 2011 to 2018. Univariate and multivariate logistic regression was used to evaluate the effects of maternal age on pregnancy outcomes. Results A total of 63,137 women categorized into different age groups (

Purpose: To evaluate visual acuity (VA) outcomes and complications from resident physician-performed cataract surgery in a diverse Veterans Affairs Hospital population. Methods: A retrospective chart review was conducted for patients who underwent cataract surgery performed by resident physicians from 01/01/2013 to 12/31/2015 at the Veterans Affairs Medical Center. Intraoperative and postoperative clinical information, best-corrected VA (BCVA) (1 day, months 1, 2-3, and 6), and surgery complications were extracted. Univariable and multivariable linear regression models were performed for risk factors of BCVA change. Results: This study included 1183 patients, with mean (SD) age of 70.8 (9.3) years. 1154 (97.5%) were males, 493 (41.7%) African-American, and 681 (57.6%) Caucasian. The mean (SD) VA in logMAR was 0.69 (0.74) at baseline, improved to 0.19 (0.36) at 1 month, 0.16 (0.34) at 2-3 months, and 0.14 (0.36) at 6 months. 1080 (91.3%) patients experienced VA improvement from baseline and 1023 (86.5%) patients achieved at least 20/40 BCVA at 1 month. There were 86 (7.3%) complications, most commonly including 47 (4.0%) posterior capsular tears and 64 (5.4%) vitreous loss. In multivariable analysis, younger age (P < 0.0001), worse baseline VA (P < 0.0001), and absence of iris prolapse (P < 0.001) were significantly associated with greater improvement in VA at 1 month. Conclusion: In a diverse VAMC, resident-performed cataract surgeries achieved significant improvement in VA with a cumulative complication rate lower than previously reported. Resident physician education may benefit from specific focus on prevention of iris prolapse and better incision construction during surgery as these intraoperative events often led to delayed stabilization of visual outcome beyond 1 month.

Abstract Background The severity of liver fibrosis is an important predictor of death in patients with non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM). However, there is still no definite conclusion on the relationship between triiodothyronine (T3) and the severity of liver fibrosis. Thus, the aim of this study was to analyze the correlation between T3 level and the severity of liver fibrosis. Methods We performed a cross-sectional study of 2072 T2DM patients with normal thyroid function from January 2017 to January 2020. NAFLD fibrosis score (NFS), Fibrosis index based on the 4 factors (FIB-4) and BARD score (BARD) were used to assess the severity of fibrosis in T2DM patients, and linear regression analyses were used to determine the factors independently associated with liver fibrosis. Further experiments were performed to assess the impact of low T3 on fibrosis progression in mice model and explore possible mechanisms. Results Free triiodothyronine (fT3) levels had significantly inverse correlations with NFS and FIB-4, and BARD in T2DM patients (P

Abstract Background Patients with diabetes are prone to asymptomatic hypoglycemia (AH) due to diminished ability to perceive the onset of hypoglycemia. However, the actual prevalence and influencing factors of AH in outpatients with type 2 diabetes (T2DM) have not been well investigated. Methods A total of 351 outpatients with T2DM underwent glucose monitoring by continuous glucose monitoring system (CGMS) for consecutive 72 h without changing their lifestyle and treatment regimens. Hypoglycemia is defined as a blood glucose level less than 3.9 mmol/L, which was further divided into Level 1 hypoglycemia (blood glucose 3.0–3.9 mmol/L) and Level 2 hypoglycemia (blood glucose

Abstract Purpose To estimate laryngopharyngeal reflux (LPR) changes after uvulopalatopharyngoplasty (UPPP) for obstructive sleep apnea (OSA) using the reflux symptom index (RSI) and reflux finding score (RFS) questionnaires. Methods A total of 91 participants were recruited and divided into three groups: control (n = 27), OSA mild to moderate (n = 29), and OSA severe (n = 35) groups according to polysomnography. All participants completed the preoperative RSI, and underwent blinded evaluation on videolaryngoscopy using the RFS questionnaire. Thirty‐four OSA patients who underwent UPPP surgery completed postoperative polysomnography and questionnaires again after a 6‐month follow‐up. Results The RSI score and RFS were higher in patients with OSA than in those without OSA. Patients with severe OSA also had a higher RSI score and RFS than those with mild to moderate OSA. Apnea and hypopnea index degree and percentage of recording time for

Background. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an invasive procedure that required deep sedation to suppress coughing and body movements. Deep sedation, on the other hand, has been shown to cause respiratory and circulatory depression, especially when the airway is shared with the endoscopist. Esketamine is a novel sedative and analgesic with little respiratory inhibition that appears to be an appropriate adjuvant in propofol sedation for EBUS-TBNA. We compared the efficacy and safety of esketamine combined with propofol target-controlled infusion (TCI) and propofol TCI for deep sedation in EBUS-TBNA. Methods. The study included 135 patients with ASA II-III undergoing EBUS-TBNA. They were randomly divided into two groups (group E and group P). Both groups received midazolam (0.01–0.03 mg/kg) and oxycodone (0.07–0.08 mg/kg). Then, patients in group E received 0.3 mg/kg esketamine, propofol TCI, and 0.2 mg·kg−1·h−1 esketamine for sedative maintenance. Patients in group P received only propofol TCI. The primary outcome was the dose of 1% lidocaine administrated by the endoscopist and the times of lidocaine sprays. Secondary outcome indicators were cough score, propofol dosage, patient satisfaction, endoscopist satisfaction, the incidence of sedation-related adverse effects and side effects, and recovery time. Results. Patients in group E were given significantly less lidocaine (4.36 ml/h (2.67–6.00) vs 6.00 ml/h (4.36–7.20), P

ObjectiveThis study aimed to evaluate the clinical therapeutic efficacy of anti-snake venom serum blockade in treating local tissue necrosis caused by Chinese cobra (Naja atra) bites.MethodsPatients bitten by a Chinese cobra (Naja atra) (n = 50) that met the inclusion criteria were randomly divided into two groups: the experimental group (n = 25) and the control group (n = 25). The experimental group received regular as well as anti-snake venom serum blocking treatment, whereas regular treatment plus chymotrypsin blocking therapy was given to the control group. The necrotic volumes around snake wounds in these groups were detected on the first, third and seventh days. On the third day of treatment, some local tissues in the wounds were randomly selected for pathological biopsy, and the necrosis volume of the local tissue was observed. Furthermore, the amount of time required for wound healing was recorded.ResultsOn the third and seventh days post-treatment, the necrotic volume of the wound of the experimental group was much smaller than that of the control group, and the experimental group's wound healing time was shorter than that of the control group (all p < 0.05). Moreover, the pathological biopsies taken from the control group showed nuclear pyknosis, fragmentation, sparse nuclear density, and blurred edges, and the degree of necrosis was much higher than that of the experimental group.ConclusionsAnti-snake venom blocking therapy is a new and improved therapy with good clinical effect on local tissue necrosis caused by Chinese cobra bites; moreover, it is superior to conventional chymotrypsin blocking therapy in the treatment of cobra bites. It can better neutralize and prevent the spread of the toxin, reduce tissue necrosis, and shorten the course of the disease by promoting healing of the wound. Furthermore, this treatment plan is also applicable to wound necrosis caused by other snake toxins, such as tissue necrosis caused by elapidae and viper families.Clinical trial registrationThis trial is registered in the Chinese Clinical Trial Registry, a primary registry of International Clinical Trial Registry Platform, World Health Organization (Registration No. ChiCTR2200059070; trial URL:http://www.chictr.org.cn/edit.aspx?pid=134353&htm=4).

Background: Nonalcoholic fatty liver disease (NAFLD) is the most common metabolic disease and is intertwined with cardiovascular disorders and diabetes. Chaihu Shugan powder (CSP) is a traditional Chinese medicine with a significant therapeutic effect on metabolic diseases, such as NAFLD. However, its pharmacological mechanisms remain to be elucidated.Methods: The main compounds of CSP were measured using LC-MS/MS. A network pharmacology study was conducted on CSP. Its potential active ingredients were selected according to oral bioavailability, drug similarity indices, and phytochemical analysis. After obtaining the intersected genes between drug targets and disease-related targets, the component-disease-target network and protein-protein interaction analysis were visualized in Cytoscape. GO and KEGG enrichment analyses were performed using the Metascape database. Six-week-old male C57BL/6 mice fed a high-fat high-fructose diet for 16 weeks plus chronic immobilization stress for 2 weeks, an in vivo model, were administered CSP or saline intragastrically. Liver histology, triglyceride and cholesterol levels, ELISA, and RT-PCR were used to assess hepatic inflammation and steatosis. Immunohistochemistry and western blotting were performed to assess protein levels.Results: A total of 130 potential target genes in CSP that act on NAFLD were identified through network pharmacology assays, including tumor necrosis factor (TNF), interleukin-6 (IL6), interleukin-1β (IL-1β), and peroxisome proliferator-activated receptor γ (PPARG). KEGG enrichment analysis showed that the main pathways were involved in inflammatory pathways, such as the TNF and NF-κB signaling pathways, and metabolism-related pathways, such as the MAPK, HIF-1, FoxO, and AMPK signaling pathways. The results in vivo showed that CSP ameliorated liver inflammation and inhibited hepatic fatty acid synthesis in the hepatocyte steatosis model. More specifically, CSP therapy significantly inhibited the expression of tumor necrosis factor α (TNFα), accompanied by a decrease in TNF receptor 1 (TNFR1) and the ligand availability of TNFR1.Conclusion: Through the combination of network pharmacology and in vivo validation, this study elucidated the therapeutic effect of CSP on NAFLD, decreasing liver inflammation and inhibiting hepatic fatty acid synthesis. More specifically, the anti-inflammatory action of CSP was at least partially mediated by inhibiting the TNFα/TNFR1 signaling pathway.

In literature, learning with expert advice methods usually assume that a learner always obtain the true label of every incoming training instance at the end of each trial. However, in many real-world applications, acquiring the true labels of all instances can be both costly and time consuming, especially for large-scale problems. For example, in the social media, data stream usually comes in a high speed and volume, and it is nearly impossible and highly costly to label all of the instances. In this article, we address this problem with active learning with expert advice, where the ground truth of an instance is disclosed only when it is requested by the proposed active query strategies. Our goal is to minimize the number of requests while training an online learning model without sacrificing the performance. To address this challenge, we propose a framework of active forecasters, which attempts to extend two fully supervised forecasters, Exponentially Weighted Average Forecaster and Greedy Forecaster, to tackle the task of online active learning (OAL) with expert advice. Specifically, we proposed two OAL with expert advice algorithms, named Active Exponentially Weighted Average Forecaster (AEWAF) and active greedy forecaster (AGF), by considering the difference of expert advices. To further improve the robustness of the proposed AEWAF and AGF algorithms in the noisy scenarios (where noisy experts exist), we also proposed two robust active learning with expert advice algorithms, named Robust Active Exponentially Weighted Average Forecaster and Robust Active Greedy Forecaster. We validate the efficacy of the proposed algorithms by an extensive set of experiments in both normal scenarios (where all of experts are comparably reliable) and noisy scenarios.

Background: Stable angina is a common condition with high morbidity and mortality rates. It has been reported that combining oral Chinese patent medicines (OCPMs) and Western medicine (WM) could potentially achieve a better effect than WM alone. However, the optimal OCPMs for stable angina remain controversial and merit further empirical research.Methods: PubMed, Embase, Web of Science, Cochrane Library, Ovid-Medline, Clinical Trials.gov, China National Knowledge Infrastructure, Wanfang Database, Weipu Journal Database, and Chinese Biomedical Literature Database were all searched from inception to 13 March 2022. We employed Version 2 of the Cochrane risk-of-bias tool (ROB2) to assess the overall quality of the selected studies. We also used R 4.1.2 and STATA 14.0 software applications to perform network meta-analysis, followed by sensitivity and subgroup analysis.Results: A total of 179 randomized controlled trials with 16,789 patients were included. The selected trials were all assessed as some concerns. OCPMs combined with WM had a better treatment effect than WM alone. In terms of the effective clinical rate, a significant increase was detected for Qishen Yiqi dripping pill (QSYQ)+WM as compared with Shensong Yangxin capsule (SSYX)+WM, Shexiang Baoxin pill (SXBX)+WM, Tongxinluo capsule (TXL)+WM, Xuefu Zhuyu capsule (XFZY)+WM, Qiliqiangxin capsule (QLQX)+WM, Naoxintong capsule (NXT)+WM, Fufang Danshen dripping pill (FFDS)+WM, and Danlou tablet (DL)+WM. QSYQ + WM had the highest-ranking probability (98.12%). Regarding the effective rate in ECG, QSYQ + WM was superior to SXBX + WM, TXL + WM, DL + WM, FFDS + WM, and NXT + WM. QSYQ + WM ranked first (94.21%). In terms of weekly frequency of angina, QLQX + WM obtained a better effect than FFDS + WM, Kuanxiong aerosol (KXQW)+WM, NXT + WM, QLQX + WM, SSYX + WM, SXBX + WM, and TXL + WM. QLQX + WM ranked first (100.00%). Regarding the duration of an angina attack, KXQW + WM was superior to SSYX + WM; KXQW + WM ranked first (95.71%). Adverting to weekly nitroglycerin usage, TXL + WM had the highest-ranking probability (82.12%). Referring to cardiovascular event rate, DL + WM had the highest effect (73.94%). Additionally, SSYX + WM had the lowest rate of adverse drug reactions (1.14%).Conclusion: OCPMs combined with WM had a higher efficacy. QSYQ + WM, QLQX + WM, KXQW + WM, TXL + WM, DL + WM, SSYX + WM, and SXBX + WM merit further investigation. SXBX + WM is presumably the optimal treatment prescription for both clinically effective and cardiovascular event rates. Further high-quality empirical research is needed to confirm the current results.Systematic Review Registration: URL = https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=316534, CRD 42022316534

ObjectiveStudies have shown that sex differences in lean mass, concentrations of sex hormones, and lifestyles influence cle health and glucose metabolism. We evaluated the sex-specific association between low muscle mass and glucose fluctuations in hospitalized patients with type 2 diabetes mellitus (T2DM) receiving continuous subcutaneous insulin infusion (CSII) therapy.MethodsA total of 1084 participants were included. Body composition was determined by dual-energy X-ray absorptiometry. Intraday blood glucose fluctuation was estimated by the Largest amplitude of glycemic excursions (LAGE) and standard deviation of blood glucose (SDBG).ResultsThe prevalence of low muscle mass was higher in males than in females (p

Background: Acute tonsillitis has high morbidity. Chinese herbal injections (CHIs) were reported to be useful in treating acute tonsillitis and might reduce the probability of antibiotic resistance. Nevertheless, the optimal strategy for combining CHIs with western medicine (WM) to treat acute tonsillitis remains unclear.Methods: We retrieved data from the following databases with retrieval time from inception to 11 January 2022: PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Wanfang Database, Weipu Journal Database, and Chinese Biomedical Literature Database. Version 2 of the Cochrane risk-of-bias tool (ROB2) was used for evaluating the quality of the included studies. R 4.1.2, STATA 14.0, and Python 3.10.4 were employed for network meta-analysis, with 5-dimensional K-means cluster analysis, meta-regression analyses, sensitivity analyses, and subgroup analyses.Results: A total of 110 randomized controlled trials including 12,152 patients were included. All the studies were rated as “high risk” and “some concerns”. In terms of improving clinical effectiveness rate, Qingkailing injection + WM ranked ahead of other interventions (89.51%). Regarding reducing antipyretic time, Reduning injection + WM had the highest-ranking probability (68.48%). As for shortening sore throat relief time, Shuanghuanglian injection + WM ranked first (76.82%). Concerning shortening red and swollen tonsils relief time, Yanhuning injection + WM possessed the highest-ranking probability (89.17%). In terms of reducing tonsillar exudate relief time, Xuebijing injection + WM ranked ahead of the other interventions (94.82%). Additionally, the results of the cluster analysis suggested that Xuebijing injection + WM, Reduning injection + WM, and Yanhuning injection + WM were probably the best interventions. Furthermore, adverse drug reactions rate of Xuebijing injection + WM, Reduning injection + WM, Yanhuning injection + WM, Qingkailing injection + WM, and Shuanghuanglian injection + WM were individually 0.00%, 3.11%, 3.08%, 4.29%, and 4.62%.Conclusions: CHIs + WM have a better impact on patients with acute tonsillitis than WM alone. Xuebijing injection, Reduning injection, and Yanhuning injection might have potential advantages in treating the disease. Concerning adverse drug reactions, Xuebijing injection is presumably the optimal CHI. More high-quality studies are needed to further confirm our findings.Systematic Review Registration: CRD42022303243; URL= https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=303243

Abstract The same thyroid hormone receptor B gene (THRB) mutation led to thyroid hormone resistance with different clinical manifestations in the kindreds.

AimsNocturnal asymptomatic hypoglycemia (NAH) is a serious complication of diabetes, but it is difficult to be detected clinically. This study was conducted to determine the largest amplitude of glycemic excursion (LAGE) to predict the episodes of NAH in outpatients with type 2 diabetes.MethodsData were obtained from 313 outpatients with type 2 diabetes. All subjects received continuous glucose monitoring (CGM) for consecutive 72 hours. The episodes of NAH and glycemic variability indices (glucose standard deviation [SD], mean amplitude of plasma glucose excursion [MAGE], mean blood glucose [MBG]) were accessed via CGM. LAGE was calculated from self-monitoring blood glucose (SMBG).ResultsA total of 76 people (24.3%) had NAH. Compared to patients without NAH, patients with NAH showed higher levels of glucose SD (2.4 ± 0.9 mmol/L vs 1.7 ± 0.9 mmol/L, p

Background: Septic shock is associated with high morbidity and mortality. Studies have reported that Chinese herbal injections (CHIs) in combination with Western medicine (WM) were more favorable. However, the debate on optimal CHIs is ongoing. The objective of this study is to explore the comparative effectiveness of CHIs for septic shock.Methods: We retrieved data from the English and Chinese databases with retrieval time from database inception to 30 September 2021. Network meta-analysis was performed, with evaluation of methodological quality among the included studies and assessment of strength of evidence among the outcomes.Results: A total of 77 RCTs with 5,647 patients were included. All the studies were rated as some concerns. In terms of 28-days-mortality, Yiqifumai injection (YQFM)+WM, Shuxuetong injection (SXT)+WM, Xuebijing injection (XBJ)+WM, and Shenfu injection (SF)+WM were better than WM; YQFM + WM and SXT + WM were superior for Shenmai injection (SM)+WM; YQFM + WM was superior for SF + WM; YQFM + WM ranked first. Regarding ICU length of stay, SF + WM and XBJ + WM were better than WM; XBJ + WM was superior for SF + WM; XBJ + WM ranked first. Concerning hospital length of stay, Shenqifuzheng injection (SQFZ)+WM, Shengmai injection (SGM)+WM, and XBJ + WM had greater potential than WM and SF + WM; SQFZ + WM ranked first. As for SOFA score at 7-days, XBJ + WM and SF + WM were superior for WM; XBJ + WM was superior for SF + WM; XBJ + WM ranked first. Regarding procalcitonin level at 7-days, SF + WM, SM + WM, and Xiyanping injection (XYP)+WM were better than WM; XYP + WM was superior for SF + WM, SGM + WM, SM + WM, Danshen injection (DS)+WM, and XBJ + WM; XYP + WM ranked first. Concerning serum lactate level at 7-days, SF + WM and SM + WM were more effective than XBJ + WM and WM; SM + WM ranked first. The comparisons were rated as moderate (15.05%), low (40.86%), and very low quality (44.09%); the strength of evidence of ranking probability for hospital length of stay was low whereas the remaining outcomes were rated as very low.Conclusions: CHIs combined with WM might have higher efficacies for septic shock than WM alone. YQFM, XBJ, SQFZ, XYP, SM, SGM, and SF may be the potential optimal CHIs for septic shock. More and better evidence is needed to validate the conclusions.Systematic Review Registration:https://www.crd.york.ac.uk/prospero/display_record.php?, identifier CRD42021282958.

Objective: To explore the independent associations of the new adiposity indices lipid accumulation product (LAP) index, visceral adiposity index (VAI), and product of triglycerides and glucose (TyG) with the risks of hepatic steatosis (HS) in women with polycystic ovary syndrome (PCOS). Design: This is a cross-sectional study with 101 women with PCOS undergoing controlled attenuation parameter (CAP) measurement who were recruited from November 2018 to August 2019. Multivariable logistic regression analysis was performed to determine the associations of adiposity indices with HS. Result(s): Among the 101 PCOS patients, the prevalence rate of HS was 70.3%. The PCOS patients with HS have higher percentage of overweight/obesity status, higher level of aminotransferase (AST and ALT), homeostasis model assessment of insulin resistance (HOMA-IR), LAP, VAI, TyG, waist circumference (WC), and BMI (P < 0.05). Partial correlation analysis showed LAP, WC and BMI were significantly p ositively associated with CAP (P < 0.05) after controlling for confounding factors. Besides, BM I, WC, and CAP were gradually elevated with the increase of LAP level. Further, multivariable logistic regression analysis showed adjusted odd ratio (OR) with associa ted 95% CI (OR (95% CI)) were respectively 1.09 (1.03–1.16) for LAP, 1.14 (1.05–1.23) fo r WC, 1.28 (1.08–1.51) for BMI, respectively. Conclusions: The present study demonstrates that in women with PCOS, except for the traditional adiposity indices (WC and BMI), LAP is independently correlated with the risk of HS.

BackgroundObstructive sleep apnea-hypopnea syndrome (OSA) may cause liver fibrosis, and liver fibrosis serum biomarkers plays an important role on the diagnosis of liver fibrosis. In addition, this study aimed to observe the changes of 4 serum markers and Chitinase 3-like protein 1 (CHII3L1) levels in OSA patients with different disease severity and explore their interactions. And then, we examined whether intermittent hypoxia (IH) exposure can activate hepatic stellate cell.Methods74 OSA patients in Second Xiangya hospital from January 2021 to October 2021 was selected and categorized into mild, moderate, and severe groups according to AHI. In addition, 20 subjects were selected as the control group. Serum levels of liver fibrosis markers were determined by electrochemiluminescence immunoassay. Hepatic stellate cells were exposed to intermittent IH or normoxia (RA). Results were analyzed using the SPSS software.ResultsThere was a significant increase in serum hyaluronic acid (HA), collagen type IV (CIV) and CHI3L1 levels in OSA patients compared with control group. Specifically, serum liver fibrosis markers HA, CIV and CHI3L1 levels were positively correlated with apnea-hypopnea index (AHI), but negatively correlated with the lowest saturation oxygen (LSaO2) respectively. The LX-2 cells (human hepatic stellate cell line) exposed to IH showed significant increases in fibrotic protein expression.ConclusionOSA might either directly or indirectly trigger or exacerbate liver fibrosis, possibly via IH-related pathways.

Background: Childhood obesity is an important public health problem, which may lead to increase risk of obesity in adulthood. The relationship between the incidence of obesity and the mode of delivery is not clear. Cesarean section（CS） may be one of the risk factors of obesity in children. We investigated the relationship between the mode of delivery of pregnant women and the risk of overweight/obesity in children of all ages from 1 to 4 years. Methods: Registered in the maternal and child registration system of Xiamen city, newborns born between January 2011 and December 2012 were followed up to 4 years old. Results: 9964 cases were included in the study, of which 3462 cases (34.7%) were cesarean deliveries. From 1 to 4 years old, BMI Z-scores and the risk for overweight/obesity of children delivered by CS was higher than by the vagina. Longitudinal analysis of anthropometric assessed during study visits from 1 to 4 years offspring exposed to CS showed that after adjustment for kinds of effect factors, the changes in BMI Z-scores were 0.04 (95% CI 0.01 to 0.09，P=0.003), significantly higher than vaginal delivery, and the risk incidence of overweight/obesity increased 8% in CS offspring, OR=1.08(1.01 to 1.21, P

This study aimed to evaluate the influence of stocking density on growth performance, nutritional quality, and immune-related gene expression of Eriocheir sinensis and water quality in pond ecosystems. E. sinensis were randomly divided into five density groups (G1: 1.2 inds/m2; G2: 1.5 inds/m2; G3: 1.8 inds/m2; G4: 2.1 inds/m2; G5: 2.4 inds/m2) based on their breeding densities, and three replicates were set up for each density group, for a total of fifteen ponds. After 169 days of breeding, the muscle, hepatopancreatic tissue, and hemolymph of E. sinensis, randomly selected from each group, were collected for analysis. Body weight (BW), carapace length, and carapace width increased with breeding time, and the BW of E. sinensis in G3 was higher than that in the other groups. In the muscle and hepatopancreas, the crude lipid content in the G3 group was higher than that in the other groups (p > 0.05). In the muscle tissue, the contents of total, essential, and delicious amino acids in the G3 group were higher than those in the other groups. The expression levels of immune-related genes in G5 were higher than those in the other groups. The value of pH decreased and NO2-N increased significantly in the G5 group and pH, as a synergetic factor of culture density, affected the growth performance of E. sinensis. In conclusion, stocking density has a certain impact on the growth performance, nutrition quality, and immunity of E. sinensis and water quality in pond ecosystems, and a stocking density of 1.8 inds/m2 can be considered optimal for rearing in pond ecosystems of the Poyang Lake region.

The urbanized world has brought social, economic, and environmental sustainability into challenged surroundings in rapidly rising countries, thereby requiring the exploration of their intertwined relationships. This study regarded Brazil, India, and China as "BIC" countries to be the representative study areas for our investigation of sustainability in the context of rapid urbanization. In general, our work was synthesized into a comparison framework in four aspects: rural-urban relation, industrial development, city development, and urban landscape pattern. We determined that rural-urban dichotomy exists in all study areas, with India and China having a high degree. China was identified as a manufacturing-based country in the past half-century, whereas Brazil and India have the service sector as their primary industry. The distribution of large cities follows a regional pattern, with Brazil being northeast-focused, China being southeast-focused, and India being comparatively balanced. The Amazon forest in the north brings great challenges to Brazil with respect to the conservation of its biodiversity and eco-environment. India and China have encountered tremendous urban expansion or sprawl in the past several decades. The sustainability issues in social, economic, and environmental aspects for Brazil, India, and China were summarized in the context of rapid urbanization to provide references for other countries.

Abstract Aims/Introduction Diabetes prevalence in China has increased, but the trend in gestational diabetes mellitus prevalence is unclear. The objective of the present study was to examine the prevalence of gestational diabetes in Xiamen, China, and its association with maternal risk factors. Materials and Methods This linked‐database cohort study used the Medical Birth Registry of Xiamen. Between 1 March 2011 and 30 March 2018, 78,572 women who were diagnosed with gestational diabetes mellitus (GDM) were enrolled in the study. Maternal factors associated with the prevalence of GDM were examined using multivariate logistic regression. Results A total of 13,738 (17.6%) pregnant women were diagnosed with GDM according to the International Association of Diabetes and Pregnancy Study Groups criteria. GDM prevalence ranged from 15.5% (2012) to 19.9% (2017). Increasing age was associated with GDM; women aged >40 years versus those aged >25 years had an adjusted odds ratio (OR) of 5.91 (95% confidence interval [CI] 4.202–8.314). A positive correlation was observed between weight and GDM risk; obese women versus normal‐weight women had an adjusted OR of 2.508 (95% CI 2.253–2.792). Family history of diabetes and hypertension were more commonly observed among women with GDM. Multivariate analysis showed that family history of diabetes (OR 1.101, 90% CI 1.028–1.180), weight gain during early pregnancy (OR 1.087, 90% CI 1.052–1.124) and systolic blood pressure (OR 1.015, 90% CI 1.011–1.020) were risk factors associated with GDM incidence. Conclusions GDM affects 17.6% of all pregnant women in Xiamen. Age and maternal obesity were major contributors to GDM. The trend of GDM risk remained stable during the study.
