Abstract
Biomechanical microenvironment refers to a variety of mechanical signals in the extracellular mechanical microenvironment, which will change correspondingly with time and space. It plays an important role in histological changes such as cell migration, proliferation, and differentiation, and can further affect wound healing. Wound healing is a complex pathophysiological process, and one of the important factors that affects wound healing is whether the cells can efficiently and quickly migrate to the wound center or not. Previous studies have shown that biomechanical microenvironment can not only induce the directional migration of cells, but also improve the migration rate of cells. In the complex natural environment, cells adopt various migration patterns and are dominated by special patterns such as local myosin contractility and extracellular microenvironment. In addition to overcoming the extracellular barrier, cells also need to interact with neighboring cells and tissue through local physical and mechanical forces and signals to complete migration and thus accelerate wound healing. Therefore, in recent years, scholars at home and abroad have been actively developing biological materials based on improving biomechanical microenvironment in order to further promote cell migration and thus accelerate wound healing. This paper reviews the recent research advances on the role of biomechanical environment in wound healing promotion via the regulating of cell migration and the development of related biomaterials.

Abstract
Objective: To evaluate the feasibility, robustness and reproducibility of radiomics features derived from lung diffusion-weighted imaging (DWI). Methods: Thirty patients with pulmonary nodules/masses who underwent magnetic resonance imaging examination in the Department of Radiology, the First Affiliated Hospital of Guangzhou Medical University, from January 4 2019 to May 5 2019, including 16 males and 14 females, aged from 27 to 69 (57±11) years, were prospectively collected. Planar echo imaging (EPI) -DWI and fast spin-echo (TSE) -DWI scans were performed under free-breathing conditions. Each scan was repeated at an interval of 5 minutes, and the corresponding apparent diffusion coefficient (ADC) maps were reconstructed. Each DWI and ADC sequence (a total of eight groups of images) were manually segmented by two radiologists, and a total of 396 radiomics features in 6 categories were extracted from each group of images. Consistency correlation coefficient (CCC) and dynamic range (DR) were used to evaluate the robustness of features between two scans, and stable features were defined as both CCC values and DR values ≥0.85. Intra-observer and interobserver reproducibility were evaluated by intra-group correlation coefficient (ICC), and ICC values≥0.75 was considered to be good reproducibility. Results: Regardless of EPI or TSE technique, the number of robust features extracted fromDWI (TSE: n=197, EPI: n=169) were higher than that of the corresponding ADC (TSE: n=126, EPI: n=148). The proportion of robust features of TSE-DWI、EPI-DWI、TSE-ADC、EPI-ADC was 49.7% (197/396), 42.7% (169/396), 31.8% (126/396) and 37.4% (148/396), respectively. Of the 396 features, 54 (13.6%) of them demonstrated great robustness (CCC and DR≥0.85) and interobserver and interobserver reproducibility (ICC≥0.75) across all sequences. Conclusions: Radiomics features derived from lung DWI showed robustness and reproducibility. Different sequences and different feature clusters have different proportions of stable features, and some features have good robustness and reproducibility between different scans, different observers, and even different sequences.

Abstract
We present a combined experimental and theoretical study of the ultrafast transient absorption spectroscopy results of a {Ni2Dy2}‐compound in DMF, which can be considered as a prototypic molecule for single molecule magnets. We apply state‐of‐the‐art ab initio quantum chemistry to quantitatively describe the optical properties of an inorganic complex system comprising ten atoms to form the chromophoric unit, which is further stabilized by surrounding ligands. Two different basis sets are used for the calculations to specifically identify two dominant peaks in the ground state. Furthermore, we theoretically propagate the compound's correlated many‐body wavefunction under the influence of a laser pulse as well as relaxation processes and compare against the time‐resolved absorption spectra. The experimental data can be described with a time constant of several hundreds of femtoseconds attributed to vibrational relaxation and trapping into states localized within the band gap. A second time constant is ascribed to the excited state while trap states show lifetimes on a longer timescale. The theoretical propagation is performed with the density‐matrix formalism and the Lindblad superoperator, which couples the system to a thermal bath, allowing us to extract relaxation times from first principles.

Abstract
Porphyromonas gingivalis is responsible for the destruction of cementum in patients with periodontitis and periapical periodontitis. However, research about the effects of P. gingivalis on cementoblast mineralization and the underlying mechanism is still lacking. Casein kinase 2 interacting protein 1 (Ckip-1) is a scaffold protein that interacts with various proteins and signals to regulate different cell functions, such as cell morphology, apoptosis, and differentiation. In this study, we verified the suppressive effects of P. gingivalis and lipopolysaccharide (Pg-LPS) on OCCM-30 mineralization. We also showed that Ckip-1 gradually decreased during OCCM-30 mineralization but increased with the aggravation of Pg-induced inflammation. However, it remained unchanged when cells were stimulated with Pg-LPS, regardless of the concentration and incubation time. Then, more cellular cementum and enhanced Osterix expression were observed in Ckip-1 knockout mice when compared with the wild-type mice. Meanwhile, Ckip-1 silencing significantly enhanced cementoblast mineralization with or without P. gingivalis-associated inflammation. The trend was opposite when Ckip-1 was overexpressed. Finally, we found that the p38, Akt, and Wnt pathways were activated, while the Erk1/2 pathway was inhibited when Ckip-1 was silenced. The opposite results were also observed in the Ckip-1 overexpression group. Furthermore, we proved that cell mineralization was weakened when p38, Akt inhibitors were applied and strengthened when the Erk1/2 pathway was inhibited. In summary, Ckip-1 is upregulated underP. gingivalis-induced inflammation and negatively regulates cementoblast mineralization partially through mitogen-activated protein kinases and Akt signaling pathways, which may contribute to the restoration of cementum destroyed by P. gingivalis.

Abstract
Objective: To elucidate the clinical characteristics of bloodstream infection in patients with allogeneic hematopoietic stem cell transplantation (allo-HSCT) in our hospital and improves the survival of transplant patients with bloodstream infection. Methods: Two hundred and ten patients with allo-HSCT from the Department of Hematology were retrospectively analyzed between October 2014 and September 2019. Pathogen distribution, drug resistance, risk factors, and outcomes were investigated in 49 allo-HSCT patients with bloodstream infections. Results: Forty-nine of 210 patients with allo-HSCT had bloodstream infection, and 59 pathogenic microorganisms were identified, mainly Gram-negative bacteria (67.8%) , of which E. coli had the highest incidence (23.7%) , CRO accounted for 42.5%, and Grampositive bacteria accounted for 23.7% (without vancomycin or linezolid-resistant strain) . Additionally, fungi accounted for 8.5%. Univariate analysis suggested that the risk factors of bloodstream infection were gender, pretransplant disease status, and conditioning regimen. In contrast, multivariate analysis showed that bloodstream infection was mainly related to conditioning regimens. Further grouping results showed that 77.6% of patients with neutropenia had bloodstream infections, and 22.4% of patients with non-neutropenia had bloodstream infections; 81.0% of patients with active infections before transplantation had bloodstream infections, while bloodstream infection occurred in 16.9% of patients without active infection. Survival analysis showed that long-term survival of patients with bloodstream infection is shorter than that of patients without bloodstream infection and long-term survival of patients with CRO infection is shorter than that of patients without CRO infection. The survival of patients with neutropenia longer than 14 d is shorter than that of patients with neutropenia shorter than 14 d. Furthermore, there is no correlation between whether there is an active infection before transplantation and whether they are in a neutropenic state at the time of infection and survival. Conclusion: Our results suggest that effective prevention of bloodstream infections from drug-resistant bacteria, particularly CRO, shortening the duration of neutropenia, eradication of potential infections before transplantation, and patient-adaptive conditioning could reduce transplant-related mortality and improve prognosis.

Abstract
Abstract
Background
Despite regional variation in survival following out-of-hospital cardiac arrest (OHCA), few studies have investigated urban-rural differences in the provision of care and outcomes after OHCA. To better understand the role of pre-hospital care across the urban-rural spectrum, we compared the effects of bystander cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) use on survival after OHCA between geographical settings.
Methods
This retrospective study (2013–2019) used all adult, non-traumatic, and treated OHCAs registered in the Cardiac Arrest Registry to Enhance Survival. The urban/rural status of arrest locations were classified at the census tract level as urban, suburban, large rural, small town, or rural, using the Rural-Urban Commuting Area classification system (Figure). Bystander interventions were grouped into three categories, including no bystander intervention, bystander CPR alone, and bystander AED use (with CPR). The primary outcome of interest was survival to hospital discharge with good neurological outcome. Multivariable logistic regression models were developed to assess the association between bystander interventions and survival with good neurological outcome by urban/rural status, adjusting for relevant covariates.
Results
A total of 325,281 patients were included. Bystander CPR alone occurred most often in rural areas (50.8%), and least often in urban areas (35.4%). Bystander AED use varied by urban/rural status (1.7%-2.9%), with large rural (2.9%) and rural areas (2.4%) reporting the highest rates. Survival to hospital discharge with good neurological outcome differed for urban (8.1%), suburban (7.7%), large rural (9.1%), small town (7.1%), and rural areas (6.1%). In all areas, patients who received bystander AED use or bystander CPR alone were more likely to achieve survival with good neurological outcome than patients who received no bystander intervention. The effect of bystander AED use on survival was stronger than bystander CPR alone in urban, suburban, and rural areas (no overlap of confidence bands), whereas no significant differences between these two bystander intervention groups were observed in large rural areas or small towns (overlap of confidence bands) (Table).
Conclusions
Bystander CPR and AED use are critical components of the response to OHCA across the urban-rural spectrum. The relative impact of bystander interventions on survival varied based on the geographical location of arrests, despite adjusting for numerous potential confounding variables, such as response time. It is possible that unmeasured factors, such as time from collapse to bystander intervention, patient factors, AED accessibility, and CPR quality are contributing to these observed differences. Future research is needed to better understand the response to OHCA across the urban-rural spectrum, which may inform policies for community-specific emergency protocols and planning.

Abstract
Purpose Lysophosphatidic acid (LPA) is a bioactive molecule which participates in many physical and pathological processes. Although LPA receptor 6 (LPAR6), the last identified LPA receptor, has been reported to have diverse effects in multiple cancers, including breast cancer, its effects and functioning mechanisms are not fully known. Methods Multiple public databases were used to investigate the mRNA expression of LPAR6, its prognostic value, and potential mechanisms in breast cancer. Western blotting was performed to validate the differential expression of LPAR6 in breast cancer tissues and their adjacent tissues. Furthermore, in vitro experiments were used to explore the effects of LPAR6 on breast cancer. Additionally, TargetScan and miRWalk were used to identify potential upstream regulating miRNAs and validated the relationship between miR-27a-3p and LPAR6 via real-time polymerase chain reaction and an in vitro rescue assay. Results LPAR6 was significantly downregulated in breast cancer at transcriptional and translational levels. Decreased LPAR6 expression in breast cancer is significantly correlated with poor overall survival, disease-free survival, and distal metastasis-free survival, particularly for hormone receptor-positive patients, regardless of lymph node metastatic status. In vitro gain and loss-of-function assays indicated that LPAR6 attenuated breast cancer cell proliferation. The analyses of TCGA and METABRIC datasets revealed that LPAR6 may regulate the cell cycle signal pathway. Furthermore, the expression of LPAR6 could be positively regulated by miR-27a-3p. The knockdown of miR-27a-3p increased cell proliferation, and ectopic expression of LPAR6 could partly rescue this phenotype. Conclusion LPAR6 acts as a tumor suppressor in breast cancer and is positively regulated by miR-27a-3p.

Abstract
Objective: To investigate the epidemiological characteristics and etiological distribution of infection on 3 067 hospitalized pediatric patients with burns, and explore the prevention and treatment strategy of pediatric burns. Methods: A cross-sectional survey was conducted. An analysis was performed on the data of 3 067 hospitalized pediatric patients with burns who met the inclusion criteria and were admitted to the First Affiliated Hospital of Army Medical University (the Third Military Medical University) from January 2012 to December 2020, including gender, age, causative factors, locations and severities of burns, seasons of accidents, and the type, source of tissue or body fluid, and drug resistance of pathogenic bacteria. API bacterial identification batten and automatic microbial identification system were applied for pathogen identification. Drug sensitivities of top 3 consistent ratio pathogen identifed were tested with minimum inhibitory concentration and disk diffusion method. WHONET 5.6 software was applied to analyze the data. Results: There were 3 067 hospitalized pediatric patients with burns, including 1 768 boys and 1 299 girls. The majority of pediatric burn patients were >1 and ≤4 years, accounting for 72.9% (2 236/3 067), and the minority of pediatric burn patients were >8 and ≤12 years, accounting for 4.9% (150/3 067). Moderate burns and severe burns of pediatric burn patients accounted for the majority parts, and the proportions of the two were close. The top cause of pediatric burns was scald, accounting for 81.6% (2504/3 067). Extremities were the most common burn sites in that of entire 3 254. The most pediatric burns occurred in winter, accounting for 29.4% (903/3 067). A total of 1 018 strains of pathogenic bacteria were collected from pediatric burn patients, all of which were non-repeated isolates. The pathogens with top five consistent ratio were Staphylococcus aureus, Pseudomonas aeruginosa, Acinetobacter baumannii, Enterobacter cloacae, and Escherichia coli, among which Staphylococcus aureus ranked the first every year. The pathogens were mainly isolated from the wound exudate, accounting for 81.34% (828/1 018). Staphylococcus aureus from 2012 to 2020 showed no resistance to vancomycin, linezolid or teicoplanin while Staphylococcus aureus isolated in 2019 was 100% resistant to macrolides, penicillin, aminoglycosides, and quinolones. Pseudomonas aeruginosa was not resistant to polymyxin B. Acinetobacter baumannii showed a high rate of drug resistance to most antibiotics. Conclusions: Among the pediatric burn patients admitted to the First Affiliated Hospital of Army Medical University (the Third Military Medical University) from 2012 to 2020, the majority are male children aged >1 and ≤4 years with moderate burns. Scalds are the leading cause; and extremities are the common burn sites; and the most pediatric burns occurre in winter. Staphylococcus aureus from wound exudate is the primary pathogen of burn wound infections in pediatric patients.

Abstract
Proliferation of vascular smooth muscle cells (VSMCs) participates in multiple cardiovascular disorders, while the mechanism remains unclear. This study aims to investigate the effects of insulin on VSMC. Insulin was used to stimulate rat VSMCs, and the effects on cell cycle and proliferation were subsequently analyzed using flow cytometry. Furthermore, AP-1 and SM-α overexpression vectors were constructed and transfected into VSMCs. AP-1 and SM-α were inhibited by SR11302 and SM-α siRNA, respectively. The mRNA and protein expression levels were subsequently detected using the reversetranscription quantitative polymerase chain reaction and western blotting, respectively. AP-1 and SM-α gene promoter binding sites were determined using luciferase and chromatin immunoprecipitation assays. As a result, we found that high dose of insulin promoted proliferation of VSMCs and increased the percentage of cells in the S phase by downregulating AP-1. AP-1 was identified to bind to the SM-α gene promoter at locus 2-177 to upregulate SM-α gene expression. Inhibition of AP-1 led to the decrease of SM-α expression. Overexpression of SM-α directly suppressed proliferation of VSMCs, while knocking it down promoted the process. Therefore, this study revealed that insulin downregulated the expression of the SM-α gene by inhibiting AP-1, which in turn facilitated proliferation of VSMCs.

Abstract
This study aimed to construct a vector lentivirus carrying the Smo gene and transfect pancreatic cancer cells positive for CD24CD44 surface antibody and detect the infectivity. A lentivirus carrying a specific Smo fragment was designed and synthesized, and its functionality was tested. An overexpression group, inhibitory group, and negative control group were used for subsequent experimental research and comparison. A virus was successfully designed and produced. The best viral load was the 1X106 TU virus, where the cell growth and fluorescence effect of culture wells with polybrene dilution were the best. These are the transfection conditions and transfection param-eters for subsequent experiments. This plasmid was detected with a flag antibody by Western blot. The result was that it had a large specific 250kD band, and the membrane protein was overexpressed successfully. The expression results of Smo in five groups of cells after virus transfection detected by RT-PCR: blank group were 1.0038±0.0344, CON238 negative group: 1.0276±0.2944d, CON077 negative group: 0.8793±0.0402; LV-SMO15570-2 overexpres-sion group: 2.7479±0.8308, and LV-SMO-RNAi37304-1 inhibition group: 0.2386±0.0481. There were differences among the overexpression group and inhibition group with the other three groups. Homogeneity of variance: Bartlett F = 4.3530, P = 0.0016 < 0.05, heterogeneous. K-W test: cc2 = 10.9905* P = 0.0267, and there was a statisti-cally significant difference. The designed virus achieved the goal requirements. An sRNA fragment was designed for the key gene Smo of the Hh signaling pathway, and a vector lentivirus carrying this fragment was successfully constructed. The expression of Smo was analyzed after transfecting SW1990CD24CD44 positive cells, suggesting that the function of the RNA fragment designed for the key gene Smo in this experiment was successful.

Abstract
OBJECTIVE Studies have demonstrated that long non-coding RNAs (lncRNAs) are important in the development and prognosis of prostate cancer. The aim of this study was to investigate the functions and mechanism of lnc-SNHG14 in prostate cancer. PATIENTS AND METHODS Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) or Western blot (WB) were performed to detect mRNA expressions of SNHG14 and miR-5590-3p, and the protein levels of Yin Yang-1 (YY1) in prostate cancer tissues, adjacent tissues, and cancer cell lines. The correlation analysis was used to analyze the correlations between SNHG14, miR-5590-3p, and YY1. Kaplan-Meier survival analysis was used to analyze the overall survival for prostate cancer patients. Cell Counting Kit-8 (CCK-8) assay was performed to measure cell proliferation ability and flow cytometry assay was used to detect cell apoptotic rate. Besides, transwell assay was used to measure cell invasion ability. In addition, WB was performed to measure protein expressions in prostate cancer cell lines. Finally, Luciferase reporter assay was performed to verify the binding sites between SNHG14 and miR-5590-3p, miR-5590-3p, and YY1. RESULTS The results showed that SNHG14 was significantly increased in prostate cancer tissues and prostate cancer cell lines, which were related with advanced stage and poor diagnosis for prostate cancer patients. MiR-5590-3p was reduced in prostate cancer tissues and cell lines, which were negatively correlated with SNHG14. YY1 was found to be increased in prostate cancer tissues, which was negatively correlated with miR-5590-3p and positively correlated with SNHG14. Furthermore, SNHG14 knockdown inhibited cell proliferation, invasion, and promoted cell apoptosis in DU145 cells. In addition, protein expressions of Cyclin D1, Bcl-2, and N-cadherin were repressed, and the levels of Bax, Cleaved Caspase-3, and E-cadherin were increased. Besides, miR-5590-3p inhibition promoted cell proliferation and invasion, and inhibited apoptosis in DU145 cells. Importantly, Luciferase reporter assay proved that SNHG14 could directly sponge with miR-5590-3p, which could bind with YY1 and regulate the functions of cancer cell. Finally, we proved that SNHG14 regulated cell proliferation, cell apoptosis, and invasion via miR-5590-3p/ YY1 axis in prostate cancer. CONCLUSIONS Above all, we found that SNHG14 was increased in prostate cancer patients, which was related with future diagnosis for prostate cancer patients. Of note, we discovered that SNHG14 could promote cell proliferation, invasion, and repress cell apoptosis via miR-5590-3p/YY1 axis in prostate cancer, which might provide a new target for treating prostate cancer.

Abstract
Hair-fin anchovy (Setipinna tenuifilis) is an economically important fish distributed in the West Indian Ocean and the Northwest Pacific Ocean. In this study, 154 individuals in eight populations of S. tenuifilis were sequenced and 850 million raw reads were obtained using restriction site-associated DNA sequencing (RAD-seq). First, we identified 14 012 044 hypothetical SNP markers. A dataset of 199 903 high-quality SNPs was collected after further screening. These SNPs have a strong ability to test the genetic diversity between the eight populations. The differentiation and genetic law between samples were explored based on SNPs in populations of S. tenuifilis. The results of this study will provide data for protecting the genetic resources of the species.

Abstract
Objectives: The mortality rate of sepsis remains very high. Metabolomic techniques are playing increasingly important roles in diagnosis and treatment in critical care medicine. The purpose of our research was to use untargeted metabolomics to identify and analyze the common differential metabolites among patients with sepsis with differences in their 7-day prognosis and blood PD-1 expression and analyze their correlations with environmental factors. Methods: Plasma samples from 18 patients with sepsis were analyzed by untargeted LC-MS metabolomics. Based on the 7-day prognoses of the sepsis patients or their levels of PD-1 expression on the surface of CD4+ T cells in the blood, we divided the patients into two groups. We used a combination of multidimensional and monodimensional methods for statistical analysis. At the same time, the Spearman correlation analysis method was used to analyze the correlation between the differential metabolites and inflammatory factors. Results: In the positive and negative ionization modes, 16 and 8 differential metabolites were obtained between the 7-day death and survival groups, respectively; 5 and 8 differential metabolites were obtained between the high PD-1 and low PD-1 groups, respectively. We identified three common differential metabolites from the two groups, namely, PC (P-18:0/14:0), 2-ethyl-2-hydroxybutyric acid and glyceraldehyde. Then, we analyzed the correlations between environmental factors and the common differences in metabolites. Among the identified metabolites, 2-ethyl-2-hydroxybutyric acid was positively correlated with the levels of IL-2 and lactic acid (Lac) (P < 0.01 and P < 0.05, respectively). Conclusions: These three metabolites were identified as common differential metabolites between the 7-day prognosis groups and the PD-1 expression level groups of sepsis patients. They may be involved in regulating the expression of PD-1 on the surface of CD4+ T cells through the action of related environmental factors such as IL-2 or Lac, which in turn affects the 7-day prognosis of sepsis patients.

Abstract
ABSTRACT The function and protection of the parathyroid glands are increasingly popular research topics. New Zealand white rabbits are the most commonly used animal model of parathyroid ischemia. However, information on the vasculature of their parathyroid glands is limited. We used 94 healthy New Zealand white rabbits, 3-4 months of age and 2-3kg in weight, for exploration of the parathyroid glands, which were stained using hematoxylin and eosin (HE) after removal. The following types were classified according to the relationship between the position of the inferior parathyroid gland and the thyroid: Type A, Close Type, Type B, and Distant Type. There were 188 cases, 4 where the inferior parathyroid glands were located near the dorsal side of thyroid (2.13%), 8 where the inferior parathyroid glands were located superior to the upper pole of the thyroid (4.26%), 20 where the inferior parathyroid glands were located parallel to the thyroid (10.64%), and 155 cases where the inferior parathyroid glands were located inferior to the lower pole of thyroid (82.45%). Identifying the location and classifying the vasculature of the parathyroid glands in New Zealand white rabbits will provide an anatomical model to assist in future research.

Abstract
Objective: To examine treatment outcomes of breast phyllodes tumors and the prognosis factors of local recurrence. Methods: This retrospective cohort study included 276 patients who underwent surgical resection at Breast Center, Peking University People's Hospital from January 2011 to December 2019. Tumor subtype and histopathological features were determined from pathology reports, and the deadline of follow-up was September 30th, 2020. All 276 patients underwent open surgery, including 17 patients of mastectomy, and 259 patients of lumpectomy. The enrolled patients were all female, with age of (41.5±11.3) years (rang: 11 to 76 years), and tumor diameter of 35(28) mm (M(QR)). The Kaplan-Meier method and Log-rank test were used for survival analysis. The multivariate analysis was implemented using the Cox proportional hazard model. Results: According the pathologic test, there were 191 patients of benign phyllodes tumor, 67 patients of borderline tumor and 18 patients of malignant tumor. There were 249 patients with a follow-up of more than 6 months, and 14.1% (35/249) had local recurrence. The time-to-recurrence was (28.6±22.2) months (range: 2 to 96 months), (29.1±18.1) months (range: 2 to 80 months), (32.1±30.1) months (range: 5 to 96 months) and (12.0±6.9) months (range: 8 to 20 months) for benign, borderline and malignant phyllodes tumors. Tumor diameter (≥100 mm vs.<50 mm, HR=3.968, 95%CI: 1.550 to 10.158, P=0.004) and malignant heterologous element (yes vs. no, HR=26.933, 95%CI: 3.105 to 233.600, P=0.003) were prognosis factors of local recurrence. One death from malignant phyllodes occurred after distant metastasis. The 3-year disease-free survival rates of benign, borderline and malignant phyllodes tumor were 88.2%, 81.7% and 81.4% (P=0.300). Conclusion: Phyllodes tumors have a considerable local recurrence rate, which may be associated with tumor diameter and malignant heterologous element.

Abstract
OBJECTIVE In this study, we investigated whether certain types of lipid profiles are major contributors of acute ischemic stroke (AIS). PATIENTS AND METHODS We screened 13,285 hospitalized patients in two stroke medical centers treated with thrombolysis, thrombectomy, or conventional care for anterior cerebral artery-occluded AIS, and found 266 patients. We examined their plasma lipid profiles using the cutoff values from a receiver operating characteristic (ROC) curve. We applied a multivariate logistic regression or Fisher's exact test to compare their outcomes and risk factors. We used the modified Rankin scale (mRS) score to assess the major clinical outcome of the patients 3 months after disease onset. Mortality and symptomatic intracranial hemorrhage (sICH) were both evaluated as risk factors. We analyzed symptoms' improvements at discharge as a disease outcome measure. RESULTS In the patients with anterior cerebral artery-occluded AIS (NIHSS ≥ 10) treated by intravenous (IV) thrombolysis, a total cholesterol (TC) level greater than 5.07 mmol/L predicted a poor outcome (OR 3.55, 95% CI 1.21,10.46, p=0.021). CONCLUSIONS In patients with anterior cerebral artery-occluded AIS, the TC level is a promising prognosis marker for the IV thrombolysis outcome.

Abstract
Objective: To explore the feasibility, safety and effectiveness of anatomical partial lobectomy. Methods: The clinical data of 3 336 patients with lung nodules underwent anatomical partial lobectomy in our center from November 2013 to November 2019 were retrospectively analyzed. We set the safety margin distance according to the imaging feature of the lesion. The surgeons then anatomically detached the major vessels and bronchus in this region, resected the targeted lung tissue along the plane, and completed the resection of anatomical pulmonary lobe and clean and sampling of systemic lymph nodules. Results: A total of 668 cases were multiple nodules and 2 668 cases were solitary pulmonary nodules. According to the postoperative pathological results, 283 cases were benign, 1 197 cases were preinvasive lesions (including 38 cases of atypical adenomatous hyperplasia, 445 cases of adenocarcinoma in situ and 714 cases of minimally invasive adenocarcinoma), 1 713 cases were invasive adenocarcinoma, 73 cases were non-adenocarcinoma and 70 cases were metastatic carcinoma. Among 1 786 invasive primary lung cancers, 11 cases received preoperative neoadjuvant chemotherapy, and their postoperative pathologic diagnoses were stage ypIA. Other 1 775 cases who did not receive postoperative neoadjuvant treatment included 1 587 cases in stage ⅠA, 112 cases in stage ⅠB, 3 cases in stage ⅡA, 18 cases in stage ⅡB, 37 cases in stage ⅢA, 9 cases in stage ⅢB, 9 cases in stage Ⅳ. The average operation time was (127.3±55.3) minutes, and the mean postoperative hospital stay was (4.8±2.4) days. The incidence rate of complications (grade>2) was 1.1%(38/3 336), and no death occurred during 30 days after operation. Conclusion: Anatomic partial lobectomy has good clinical applicability, safety and effectiveness, which is worthy of clinical application and recommendation.

Abstract
Objective: To investigate the effects and mechanism of copper oxide nanozymes on wound healing of full-thickness skin defects in diabetic mice. Methods: (1) Copper oxide nanozymes were synthesized through the reaction of copper chloride and L-ascorbic acid. Transmission electron microscope was used for observing the particle size and morphology of copper oxide nanozymes, and dynamic light scattering particle size analyzers and Zeta potentiometer were used to analyze the hydrated particle size and surface potential of copper oxide nanozymes, respectively. (2) The hydrogen peroxide detection kit, superoxide anion determination kit, and 3, 3', 5, 5'-tetramethylbenzidine were used to test the hydrogen peroxide, superoxide anion, and hydroxyl radicals scavenging ability of 150 ng/mL copper oxide nanozymes, respectively, and the scavenging proportions of hydrogen peroxide, superoxide anion, and hydroxyl radicals were calculated. The sample numbers were all 3. (3) Mouse fibroblast cell line 3T3 cells were divided into blank control group, simple hydrogen peroxide group, and hydrogen peroxide+ copper oxide group according to the random number table (the same grouping method below), with 3 wells in each group. Cells in hydrogen peroxide+ copper oxide group were pre-treated with copper oxide nanozymes in final mass concentration of 25 ng/mL for 30 minutes, and then hydrogen peroxide in final molarity of 250 μmol/L was added into simple hydrogen peroxide group and hydrogen peroxide+ copper oxide group. Cells in blank control group were routinely cultured. After 24 hours of culture, 2', 7'-dichlorodihydrofluorescein diacetate fluorescence probe was used to detect the level of reactive oxygen species (indicated by green fluorescence intensity) in cells and cell counting kit-8 assay was performed to detect and calculate the cell survival rate. (4) Ten male BALB/c mice aged 6-8 weeks (the same gender and age below) were divided into phosphate buffer saline (PBS) group and copper oxide group, with 5 mice in each group. The mice in the copper oxide group were injected with 800 ng/kg copper oxide nanozyme at a concentration of 200 ng/mL via the caudal vein, and the mice in PBS group were treated with the same volume of PBS. The mice in the two groups were treated once a day for seven consecutive days. On the eighth day, 5 mice from each group were conducted and blood samples were taken for analysis of blood panel and serum biochemistry, and then the heart, liver, spleen, lung, and kidney were harvested for histopathological observation by hematoxylin-eosin (HE) staining after the mice were sacrificed. (5) Twenty mice were divided into PBS group and copper oxide group, with 10 mice in each group. Diabetes was induced by streptozotocin and high-sugar and high-fat diet and a full-thickness skin defect wound with diameter of 6 mm was reproduced on the back of each diabetic mouse. Immediately after injury, 20 μL PBS and 20 μL copper oxide nanozymes at the concentration of 200 ng/mL were added respectively to the wounds of mice in PBS group and copper oxide group, with the treatment being continued for twelve consecutive days. Three mice were selected from each group, and the wound healing was observed on post injury day (PID) 0 (immediately), 3, 6, 9, and 12 and the un-healed area was calculated. On PID 6, three mice from each group that were not for wound observation were sacrificed, and the content of interleukin 1β (IL-1β), tumor necrosis factor-α (TNF-α), and IL-6 in the wound tissue were determined by enzyme-linked immunosorbent assay. On PID 12, the rest 7 mice in each group were sacrificed for observation of the length of regenerated epidermis in wound tissue by HE staining, and the level of reactive oxygen species (indicated as red fluorescence intensity) in wound tissue by dihydroethidium staining. Data were statistically analyzed with one-way analysis of variance, analysis of variance for repeated measurement, independent sample t test, and Bonferroni test. Results: (1) The prepared copper oxide nanozymes were uniform in size with an average diameter of 3.5-4.0 nm in dry state, the hydrated particle size of 4.5 nm, and the surface potential of (-9.8±0.3) mV. By comprehensive judgment, copper oxide nanozymes had been successfully prepared. (2) After being treated with copper oxide nanozyme for 2 hours, 10 minutes, and 5 minutes, respectively, the scavenging proportions of hydrogen peroxide, superoxide anion, and hydroxyl radicals were (77±5)%, (45±5)%, and (84±4)%, respectively. (3) After 24 hours of culture, the cells in simple hydrogen peroxide group showed a significantly increased level of reactive oxygen species with abnormal morphology and decrease in cell number, while the cells in hydrogen peroxide+ copper oxide group showed a remarkably decreased level of reactive oxygen species with normal morphology similar to that of blank control group. The cell survival rate in simple hydrogen peroxide group was obviously reduced compared with the rates in blank control group and hydrogen peroxide+ copper oxide group (P<0.01), while there was no significant difference in cell survival rate between hydrogen peroxide+ copper oxide group and blank control group. (4) After 7 days of injection, there were no obvious differences in liver and kidney function indexes and blood panel indexes between mice in PBS group and copper oxide group. No necrosis, hyperaemia or hemorrhage in heart, liver, spleen, lung, or kidney was observed in mice in copper oxide group, which was similar to that in PBS group. (5) Compared with that of PBS group, wounds of mice in copper oxide group showed an accelerated healing trend with less redness. On PID 6, 9, and 12, the areas of un-healed wound of mice in copper oxide group (28.8±1.9), (17.6±3.8), and (10.4±1.8) mm(2), respectively, significantly lower than (38.0±4.3), (30.2±3.0), and (24.2±3.0) mm(2) in PBS group (t=3.706, 5.075, 5.558, P<0.01). On PID 6, the content of IL-1β, TNF-α, and IL-6 in wounds of mice in copper oxide group were significantly lower than that in PBS group (t=6.115, 11.762, 11.725, P<0.01). On PID 12, the length of regenerated epidermis in wounds of mice in copper oxide group was obviously longer than that in PBS group, the level of reactive oxygen species in wounds of mice in copper oxide group was obviously lower than that in PBS group. Conclusions: Copper oxide nanozyme not only has good biocompatibility, but also has efficient reactive oxygen species scavenging activity. It can eliminate the over-expressed reactive oxygen species in the full-thickness defect wounds of diabetic mice, reduce oxidative stress and inflammation, thus promoting wound repair.

Abstract
OBJECTIVE Pancreatic cancer (PC) is one of the most common malignant tumors of the digestive system with a high degree of malignancy. Currently, there have been many studies on exosomal microRNAs (miRNAs) discovery in pancreatic cancer. This systematic review aimed to give an overview about known exosomal miRNAs and discuss their diagnostic performance, as well as prognostic value in PC. MATERIALS AND METHODS PubMed and Web of Science were used for systematic literature research for this review. This literature research was mainly to identify studies that performed plasmatic and serological testing for exosomal miRNAs in pancreatic cancer patients and controls. Two independent reviewers separately extracted data on study characteristics and results. RESULTS In total, nine prior studies were included in this review. Of which, eleven different single exosomal miRNAs and three exosomal miRNA panels were reported. CONCLUSIONS When single exosomal miRNA was used as a diagnostic tool, the specificity is generally high, but the sensitivity is commonly low. When multiple of exosomal miRNAs were used simultaneously, higher sensitivities can be obtained at relatively reasonable specificity levels with certain miRNA combinations. Developing a combination of miRNA markers may be a promising approach for early detection of pancreatic cancer.

Abstract
OBJECTIVE The purpose of this study was to identify cardiac biomarkers of disordered eating as a function of diagnostic subtype as assessed via self-report inventory. METHOD Mean heart rate (HR), systolic and diastolic blood pressure, mean R wave amplitude (mV), mean T wave amplitude (mV), QTc interval (sec), Tpeak-Tend interval prolongation (sec), QTc interval prolongation (sec), QRS prolongation (sec), and spectral indicators of cardiac dysfunction (LF/HF spectral ratio, HF spectral power) were assessed via electrocardiography among women with no eating disorder symptoms (n = 32), subclinical eating disorder symptoms (n = 92), anorexia nervosa (n = 7), bulimia nervosa (n = 89), binge eating disorder (BED: n = 20), and other specified feeding and eating disorders (OSFED: n = 19). RESULTS MANOVA results showed statistically significant group differences. Follow-up tests revealed significantly decreased mean R wave amplitude among participants with self-indicated clinical (bulimia nervosa, binge eating disorder) and subclinical forms of disordered eating compared to asymptomatic controls. DISCUSSION Results suggest decreased mean R wave amplitude is a promising cardiac biomarker of disordered eating.

Abstract
Objective: To observe the alteration of clinical features of intrahepatic lymphocyte subsets in C57BL/6N-TG (1.28HBV)/Vst hepatitis B virus (HBV) transgenic mice composite carbon tetrachloride (CCl(4)) with intraperitoneal injection under the background of hepatitis B to induce liver fibrosis mice model, and analyze their correlation with serum HBV DNA and liver tissue hydroxyproline (Hyp) content. Methods: HBV-Tg mice were intraperitoneally injected with 10% CCl(4) to induce the rapid formation of hepatic fibrosis. Serum HBV DNA, HBsAg, HBeAg levels and liver tissue HBsAg expressional conditions were used to evaluate the virological characteristics of mice model. The degree of hepatic inflammation and fibrosis in mice were observed by HE, Sirius Red staining and liver tissue hydroxyproline (Hyp) content. Intrahepatic T lymphocyte, B lymphocyte, CD4+T lymphocyte, CD8+T lymphocyte, natural killer (NK) cell and natural killer T (NKT) cells distribution were observed by flow cytometry. One-way analysis of variance was used for intergroup data comparison, and LSD was used for pairwise comparison. Pearson's correlation analysis was used to analyze the correlation between the above lymphocyte subsets and serum HBV DNA and liver tissue Hyp content. Results: Serum HBsAg, HBeAg and liver tissue HBsAg had equal positive expression in the HBV-Tg composite CCl(4) mice model group, and the serum HBV DNA load was > 1 × 10(6) IU / ml. Compared with the wild-type control group, liver tissue Hyp content of the composite model group was significantly higher [(196.39 ± 38.14) μg /g and (347.67 ± 59.53) μ g/g, P < 0.01). The degree of inflammation and fibrosis in liver tissues was aggravated, and the proportion of all intrahepatic CD4+T, NK and NKT cells was significantly reduced (P < 0.01), while the proportion of CD8+T lymphocytes (30.58% ± 2.89% vs. 46.50% ± 2.24%, P < 0.01) and B lymphocytes (28.82% ± 2.24% vs. 37.10% ± 8.59%, P < 0.05) was significantly increased. Serum HBV DNA level was positively correlated with the proportion of intrahepatic T lymphocytes (r = 0.413, P < 0.05), and negatively correlated with the proportion of NK cells (r = -0.419, P < 0.05). Liver tissue Hyp content was negatively correlated with the proportion of all CD4+T lymphocytes (r = -0.871), NK cells (r = -0.716), and NKT cells (r = -0.876) (all P < 0.01), and positively correlated with the proportion of all CD8 + T lymphocytes (r = 0.852), and B lymphocytes (r = 0.593) (all P < 0.01). Conclusion: HBV-Tg composite CCl4 mice model can induce positive HBV virological indicators, liver inflammation and fibrosis in mice model of hepatitis B coexisting with fibrosis. This model has the features of immune disorder of liver lymphocyte similar to human disease, and the immune disorder of intrahepatic lymphocytes is correlated with HBV viral load and liver fibrosis degree.

Abstract
Objective: To investigate the detection of suspected occupational diseases in the occupational health examination population in Hangzhou, and to establish a two-level logistic model of influencing factors. Methods: In October 2018, the information of physical examinees was collected through the 2015-2017 occupational health examination and reexamination database of Hangzhou Hospital for the Prevention and Treatment of Occupational Disease. MlwiN 2.02 software was used to establish a 2-level logistic model of suspected occupational diseases, with the occupational hazard factors as the level 2 unit and the employees as the level 1 unit. χ(2) test was used to compare the detection rates of suspected occupational diseases with different characteristics. The trend of detection rates of suspected occupational diseases with age and working age were tested by Cochran-Armitage trend test. Results: The morbidity rate of suspected occupational diseases in 2965 workers was 59.6% (1767/2965) , and the rates caused by different occupational hazardous factors were significantly difference (χ(2)=1615.27, P<0.01) , that caused by noises was the highest (98.0%, 1206/1231) , and the next was the dust (87.5%, 70/80) . The rate in male was 61.5% (1532/2492) , and that in female was 49.7% (235/473) , they were significantly difference (χ(2)=22.96, P<0.01) . The rates of suspected occupational diseases increased with the ages (Z=8.77, P<0.01) and working years (Z=3.62, P<0.01) . The multivariate analysis by 2-level logistic model indicated that gender, age and working year were all no significant, instead the level 2 unit random effect was significant (χ(2)=4.77, P<0.05) . Conclusion: Suspected occupational diseases will occur in clusters in occupational hazardous factors. The influence of occupational hazardous factors on suspected occupational diseases was more than that of personal characteristics.

Abstract
PURPOSE This study aimed to find the associations between vasomotor symptoms (VMS) and metabolic syndrome (MetS) in Chinese middle-aged women in a cross-sectional study. METHODS A total of 675 participants were recruited from an urban Chinese community. MetS was defined by the 2009 criteria of the Joint Interim Statement. VMS including hot flashes and sweats, blood pressure, weight, height, waist circumference (WC), serum glucose, triglycerides, high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), estradiol, and follicle-stimulating hormone (FSH) were collected. RESULTS The presence of hot flashes was independently associated with the risk of MetS after adjusting for age, menopausal status, FSHlog, estradiollog, and physical activity (odds ratio: 1.98, 95% confidence interval: 1.21-3.24, p = 0.006). Both hot flashes and sweats were also independently associated with WC (for hot flashes, p = 0.016; and for sweats, p = 0.007) and triglycerides (for hot flashes, p = 0.041; and for sweats, p = 0.014) significantly. However, VMS were not significantly associated with blood pressure, glucose, HDL, and LDL. CONCLUSION Women with hot flashes had a higher risk of MetS. Both hot flashes and sweats were related to a higher amount of central fat indicated by WC and higher triglycerides, but were not related to blood pressure, glucose, and HDL in Chinese women.

Abstract
OBJECTIVE The aim of this study was to explore the correlations of changes in inflammatory factors, glucose and lipid metabolism indicators and adiponectin with alterations in intestinal flora in rats with coronary heart disease. MATERIALS AND METHODS A total of 30 male specific pathogen-free rats were randomly assigned into two groups, including: blank group (n=15) and coronary heart disease group (n=15). The rats in the coronary heart disease group were given high-fat diets and pituitrin to establish the model of coronary heart disease. Meanwhile, rats in the blank group were administered with an equal volume of double-distilled water. The alterations in the intestinal flora of rats were detected in the two groups, respectively. In addition, the changes in the levels of inflammatory factors, glucose and lipid metabolism indicators, adiponectin, creatine kinase (CK) and its isoenzyme, as well as troponin, were also examined. RESULTS Statistically, significant differences in the levels of glucose and lipid metabolism indicators low-density lipoprotein (LDL) (p=0.040), total cholesterol (TC) (p=0.039), high-density lipoprotein (HDL) (p=0.044), triglyceride (TG) (p=0.000) and blood glucose (p=0.046) were observed between the rats in the coronary heart disease group and blank group. The content of all the glucose and lipid metabolism indicators (except HDL) in coronary heart disease group was significantly higher than the blank group (p<0.05). The rats in the coronary heart disease group had evidently higher levels of CK (p=0.000) and its isoenzyme (p=0.019), as well as troponin (p=0.021), than those in the blank group. The level of serum adiponectin in rats in coronary heart disease group was distinctly lower than that in the blank group, showing statistically significant differences (p<0.05). Besides, the levels of the inflammatory factors interleukin (IL)-2 (p=0.011), transforming growth factor (TGF)-β (p=0.048), tumor necrosis factor-α (TNF-α) (p=0.025) and IL-6 (p=0.038) in rats in the coronary heart disease group were dramatically higher than those in blank group. Rats in coronary heart disease group had remarkably more Actinobacteria, Desulfovibrio, Aristipus and Escherichia coli in the intestine. Meanwhile, the abundance of Flavobacterium, Burkhofer and some probiotics increased significantly in the intestine of rats in blank group (p<0.05). The changes in the abundance of Actinobacteria, Desulfovibrio, Aristipus and Escherichia coli in the intestine of rats were probably correlated with increased levels of glucose and lipid metabolism indicators, inflammatory factors and adiponectin in coronary heart disease group. Moreover, the abundance of intestinal probiotics such as Bifidobacterium and Lactobacillus in rats in coronary heart disease group was notably lower than that in blank group (p<0.05). The decline in the abundance of such intestinal probiotics as Bifidobacterium and Lactobacillus was correlated with the changes in the levels of glucose and lipid metabolism indicators, inflammatory factors and adiponectin. In addition, decreased levels of probiotics weakened normal physiological functions of the intestine and promoted disease progression. CONCLUSIONS Inflammatory factors, glucose and lipid metabolism indicators and adiponectin have evident changes in rats with coronary heart disease, which may be correlated with the alterations in the intestinal flora.

Abstract
Antibody levels after hepatitis B virus (HBV) vaccination may be affected by suppression of the immune system due to cancer therapy. As such, childhood acute lymphocytic leukaemia (ALL) survivors are at risk of HBV infection due to immunosuppression secondary to chemotherapy. However, the hepatitis B surface antibody (HBsAb)-seropositive rate of childhood ALL survivors after chemotherapy is unknown, and the need to revaccinate HBsAb-seronegative ALL survivors is not appreciated in China. To assess the changes in HBsAb before and after chemotherapy, we retrospectively analyzed clinical data from 547 patients treated with the Chinese Children Leukaemia Group (CCLG)-ALL 2008 protocol from 1 April 2008 to 30 August 2019. The results revealed that 416 patients (76·1%) were HBsAb-seropositive at diagnosis, and at the time of the cessation of chemotherapy, 177 patients (32·4%) were HBsAb-seropositive and 370 patients (67·6%) were HBsAb-seronegative. Interestingly, 11 patients who were HBsAb-seronegative at diagnosis converted to seropositive at the time of the cessation of chemotherapy. HBsAb titres were decreased after chemotherapy (P < 0·0001). Further, patients with higher HBsAb titres at diagnosis were more likely to maintain protective antibody titres at the completion of chemotherapy (P < 0·0001). The loss of antibody was more remarkable in younger patients (≤ 10 years) both at diagnosis (P = 0·009) and at the completion of chemotherapy (P = 0·006). In summary, this study showed that 67·6% of patients were HBsAb-seronegative at the time of the cessation of chemotherapy, which indicates that ALL survivors are at high risk of HBV. As a result, HBV revaccination after chemotherapy should be highly valued in ALL survivors.

Abstract
OBJECTIVE Demyelinating neurodegenerative diseases are some of the most important neurological diseases that threaten the health of the elderly. Astrocytes (ASTs) play an important role in the regulation of the growth and development of oligodendrocytes (OLs) and oligodendrocyte progenitor cells (OPCs), which participate in remyelination. This study investigated the mechanism by which ASTs promote the proliferation of OPCs via connexin 47 (Cx47) in OPCs. MATERIALS AND METHODS Under direct-contact co-culture conditions, we performed Cx47 siRNA interference in ASTs and OPCs and tested the cell proliferation ability by flow cytometry and with 5-ethynyl-20-deoxyuridine (EdU). We then detected Chi3l1 expression by Western blotting and immunofluorescence. Next, after the addition of exogenous Chi3l1 protein to OPCs under monoculture conditions, we tested the cell proliferation ability by flow cytometry and EdU. RESULTS After siRNA interference with Cx47, the expression of Chi3l1 decreased from 1.10±0.91 to 0.30±0.08, and the proportion of new OPCs decreased from 48.7±3.8% to 28.4±6.6%. Moreover, upon addition of exogenous Chi3l1 protein under OPCs mono-culture conditions, the expression of cyclin D1 increased from 0.68±0.09 to 1.16±0.14, leading to an increased number of OPCs in the S phase, from 7.37±1.38% to 13.55±1.60%. CONCLUSIONS Cx47/Chi3l1 plays an important role in the promotion of OPCs proliferation by ASTs. ASTs can promote the expression of Chi3l1 via Cx47 in OPCs, and then activate the expression of cyclin D1 and regulate the cell cycle of OPCs, thereby promoting cell proliferation. This study provides a new target for the treatment of neurodegenerative diseases.

Abstract
Heat stress decreases crop growth and yield worldwide. Spermidine (Spd) is a small aliphatic amine and acts as a ubiquitous regulator for plant growth, development and stress tolerance. Objectives of this study were to determine effects of exogenous Spd on changes in endogenous polyamine (PA) and γ-aminobutyric acid (GABA) metabolism, oxidative damage, senescence and heat shock protein (HSP) expression in white clover subjected to heat stress. Physiological and molecular methods, including colorimetric assay, high performance liquid chromatography and qRT-PCR, were applied. Results showed that exogenous Spd significantly alleviated heat-induced stress damage. Application of Spd not only increased endogenous putrescine, Spd, spermine and total PA accumulation, but also accelerated PA oxidation and improved glutamic acid decarboxylase activity, leading to GABA accumulation in leaves under heat stress. The Spd-pretreated white clover maintained a significantly higher chlorophyll (Chl) content than untreated plants under heat stress, which could be related to the roles of Spd in up-regulating genes encoding Chl synthesis (PBGD and Mg-CHT) and maintaining reduced Chl degradation (PaO and CHLASE) during heat stress. In addition, Spd up-regulated HSP70, HSP70B and HSP70-5 expression, which might function in stabilizing denatured proteins and helping proteins to folding correctly in white clover under high temperature stress. In summary, exogenous Spd treatment improves the heat tolerance of white clover by altering endogenous PA and GABA content and metabolism, enhancing the antioxidant system and HSP expression and slowing leaf senescence related to an increase in Chl biosynthesis and a decrease in Chl degradation during heat stress.

Abstract
Cleft palate (CP), a congenital defect in the oral and maxillofacial regions, is difficult to detect prenatally. This study investigated the correlation between differentially expressed proteins in serum and CP induced by all-trans retinoic acid (atRA) and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in mice. We studied 80 mice in the following groups: male mice (male; n = 6), nonpregnant female control mice (NP-CRL; n = 6), healthy pregnant controls (P-CRL; Con; n = 24), pregnant mice with CP induced by atRA (n = 24), or pregnant mice with CP induced by TCDD (TCDD; n = 20). Pregnant mice were given with atRA (100 mg/kg) or TCDD (40 μg/kg), or corn oil by oral gavage at E10.5. The serum samples were collected and eight proteins-including interleukin (IL)-12p40, IL-12p70, receptor for advanced glycation end products (RAGE), interferon (IFN)-γ, IFN-β, IL-10, leukemia inhibitory factor (LIF), and epiregulin-were detected by enzyme-linked immunosorbent assay. Placental tissues were immunostained for IL-12p40 and RAGE from stages E13.5 to E16.5. In P-CRL mice, serum IL-12p40 was significantly increased at E13.5 and declined over E14.5-E16.5. P-CRL had lower IFN-γ levels at E13.5 compared with NP-CRL. The CP groups showed lower concentrations of IL-12p40 at E13.5-E14.5 and clearly higher concentrations of soluble RAGE (sRAGE) at E13.5 when compared with P-CRL. IL-12p40 immunostaining clearly decreased in placental tissue sections obtained from E13.5 to E14.5 in both CP groups. These findings suggest that reduced levels of IL-12p40 and increased levels of sRAGE in serum may be correlated with chemically induced CP in mice, but further studies would be required to establish this.
