Abstract
This study was to determine the effects of the mixture of glycerol monolaurate and cinnamaldehyde (GCM) supplementation on the intestinal morphology, immunity, antioxidant status and cecal microbiota of laying hens. A total of 1,120 healthy laying hens (Jingfen-1 strain) at the age of 14 wk were randomly divided into 4 groups with 10 replicates of 28 layers in each and layers were fed diets containing 0 (control group), or 250, 500, and 1,000 mg/kg GCM for 12 wk. The results showed that dietary supplementation with GCM significantly increased intestinal villus height and villus height/crypt depth, duodenal villus area, total superoxide disumutase activities in the liver and jejunum, jejunal glutathione peroxidase activities while decreased duodenal and jejunal crypt depth, hydrogen peroxide content in the liver and jejunal malondialdehyde content of laying hens aging 28 wk (P < 0.05). Meanwhile, GCM addition significantly increased serum immunoglobulin A and immunoglobulin M concentration of layers at the age of 20, 24, and 28 wk (P < 0.05). Moreover, it was observed in the 16S rRNA sequencing that the addition of GCM elevated the abundance and diversity of gut microbiota in laying hens. The predominant bacteria from each group were Bacteroidota and Firmicutes at the phylum level and Bacteroides and Lactobacillus were the dominant genera. The composition and structure of cecal microflora were changed by the addition of GCM to the diet of laying hens. In conclusion, the addition of GCM (500-1,000 mg/kg diet) can improve intestinal morphology, immune function, intestinal and liver antioxidant status and intestinal flora of laying hens, thereby improving intestinal digestion and absorption capacity. These findings provide a new way to further explore the mechanism of GCM improving intestinal health.

Abstract
Objective: To understand the monkeypox knowledge awareness, risk perception and vaccination intention in men who have sex with men (MSM) in five cities in northeast China. Methods: A cross-sectional study was conducted by using electronic questionnaire in MSM selected by convenience sampling in five cities in northeast China (Shenyang, Panjin, Changchun, Harbin and Jiamusi) from June 28 to July 8, 2023 by local centers for disease control and prevention and MSM communities. The sample size was estimated to be 220. Information about their demographics, monkeypox-related knowledge awareness, perceived concern about epidemic risk perception, and monkeypox vaccination intention were collected. Logistic regression model was used to analyze related factors for MSM's monkeypox vaccination intention. Results: In 355 MSM, 63.9% (227/355) had monkeypox vaccination intentions, and 55.5% (197/355) had high awareness of monkeypox related knowledge with a mean knowledge awareness score of 3.7±1.5. MSM with education level of high-school and above (aOR=1.93, 95%CI:1.01-3.69), higher knowledge awareness score (aOR=1.19, 95%CI:1.02-1.40) and higher risk perception of monkeypox infection (aOR=1.82, 95%CI:1.15-2.88), were more willing to receive monkeypox vaccination. The main reasons for willingness to receive monkeypox vaccine were preventing monkeypox (86.3%, 196/227) and worrying about appearance being affected (62.1%, 141/227). The main reasons for unwillingness for the vaccination included concerns about vaccine safety (53.1%, 68/128), clinical progression of AIDS being affected (46.1%, 59/128) and efficacy of antiretroviral therapy being affected (44.5%, 57/128). Conclusions: The levels of knowledge awareness and vaccine intentions still need to be improved among MSM in five cities of northeast China. It is necessary to improve the awareness of monkeypox and intention of monkeypox vaccination, promote protected sex behavior and self-assessment of infection risk, reduce vaccine hesitancy and increase monkeypox vaccination intention in MSM in 5 cities in northeast China.

Abstract
Objective: This study aimed to investigate the viability and safety of a novel defecator in managing rectal fecal impaction. Methods: In a descriptive case series, this new defecator was administered to constipated individuals among the ages of 18 and 80 years who met the diagnostic criteria for rectal fecal impaction and were identified with acute rectal fecal impaction through CT scans. The contraindications for this defecator included: (1) Anal stenosis, acute intestinal obstruction, and intestinal perforation; (2) Concomitant rectal malignant tumors; (3) Coagulation dysfunction, low platelet counts, gastrointestinal bleeding, or other bleeding risks; (4) Patients with severe underlying conditions affecting the heart, brain, lungs, or other systems; (5) Individuals with mental health disorders. Based on these criteria, clinical data from 42 patients with rectal fecal impaction who underwent treatment with the new defecator at Deyang People's Hospital between July 2020 and April 2023 were retrospectively analyzed.The defecator comprises three components: a head, a spiral rod, and a handle, constructed from disposable stainless steel wire. The treatment procedure involves the following steps: The patient assumes a flexed, supine position on their left side with their buttocks slightly protruding from the bed's edge. A transparent sealing bag is affixed to the buttocks, centered around the anus. With gloved hands inserted through the bag's entrance, a cotton ball soaked in liquid paraffin lubricates the anal canal and the head of the defecator's spiral rod. The defecator is then slowly rotated and inserted into the anus, with careful attention to any changes in resistance. Once the spiral rod is fully inserted, the patient is instructed to inhale and defecate while the defecator is slowly withdrawn, carrying the dislodged fecal matter, and depositing it into the sealed bag. This operation is repeated 2 to 3 times, followed by the injection of either 100 ml of 36°C normal saline or 60 ml of liquid paraffin into the rectum. After a 5 to 8-minute wait, the patient assumes a squatting position to expel any remaining feces from the rectum. The study assessed the operation time, single treatment success rate, pain levels during treatment, and the occurrence of complications. Results: All 42 patients successfully underwent treatment with the new defecator device, achieving a single treatment success rate of 100%. The average operation time was 11.0 minutes (range: 9.0 to 13.3 minutes). During treatment, 20 cases (47.6%) reported moderate to severe anal pain, with 1 case (2.4%) experiencing anal fissure bleeding, and 6 cases (14.3%) reporting discomfort such as palpitations and sweating. No serious complications, including rectal perforation, were observed in any case. Conclusion: The new defecator device demonstrates ease of use and safety, making it a feasible option for treating acute rectal fecal impaction.

Abstract
Objective: To investigate the relationships between molecular types of the cancer genome atlas (TCGA) of patients with endometrial carcinoma (EC) and lymph node metastasis and other clinicopathological features. Methods: The clinical pathological information of 295 patients with EC who underwent initial inpatient surgical treatment and accepted the detection of the molecular types of TCGA with next-generation sequencing technology at Peking University People's Hospital were collected during April 2016 and May 2022. The TCGA molecular typing of EC was divided into four types: POLE-ultramutated (15 cases), high microsatellite instability (MSI-H; 50 cases), copy-number low (CNL; 175 cases), and copy-number high (CNH; 55 cases). The differences of clinical pathological features among different molecular types and the risk factors of lymph node metastasis were analyzed retrospectively. Results: Among 295 patients with EC, the average age was (56.9±0.6) years. (1) There was a statistically significant difference in lymph node metastasis (0, 8.0%, 10.3% and 25.5%) among the four molecular types (χ2=12.524, P=0.006). There were significant differences in age, stage, pathological type, grade (only endometrioid carcinoma), myometrium invasion, lymphatic vascular space infiltration, and estrogen receptor among the EC patients of four molecular types (all P<0.05). Among them, while in the patients with CNH type, the pathological grade was G3, the pathological type was non-endometrioid carcinoma, and the proportion of myographic infiltration depth ≥1/2 were higher (all P<0.05). (2) Univariate analysis suggested that pathological type, grade, myometrium infiltration depth, cervical interstitial infiltration, lymphatic vascular space infiltration, and progesterone receptor were all factors which significantly influence lymph node metastasis (all P<0.01); multivariate analysis suggested that the lymphatic vascular space infiltration was an independent risk factor for lymph node metastasis (OR=5.884, 95%CI: 1.633-21.211; P=0.007). (3) The factors related to lymph node metastasis were different in patients with different molecular types. In the patients with MSI-H, the non-endometrioid carcinoma of pathological type was independent risk factor for lymph node metastasis (OR=29.010, 95%CI: 2.067-407.173; P=0.012). In the patients with CNL, myometrium infiltration depth≥1/2 (OR=4.995, 95%CI: 1.225-20.376; P=0.025), lymphatic vascular space infiltration (OR=14.577, 95%CI: 3.603-58.968; P<0.001) were the independent risk factors for lymph node metastasis. While in the CNH type patients pathological type of non-endometrioid carcinoma (OR=7.451, 95%CI: 1.127-49.281; P=0.037), cervical interstitial infiltration (OR=22.938, 95%CI: 1.207-436.012; P=0.037), lymphatic vascular space infiltration (OR=9.404, 95%CI: 1.609-54.969; P=0.013), were the independent risk factors for lymph node metastasis. Conclusions: POLE-ultramutated EC patients have the lowest risk of lymph node metastasis, and CNH patients have the highest risk of lymph node metastasis. The risk factors of lymph node metastasis of different molecular types are different. According to preoperative pathological and imaging data, lymph node metastasis is more likely to occur in patients with non-endometrioid carcinoma in MSI-H and CNH type patients, and lymph node metastasis is more likely to occur in patients with myometrium infiltration depth ≥1/2 in CNL type patients.

Abstract
The dice lattice, containing a stack of three triangular lattices, has been proposed to exhibit nontrivial flat bands with nonzero Chern numbers, but unlike the honeycomb lattice it is much less studied. By employing density-functional theory (DFT) calculations with an on-site Coulomb repulsion term, we explore systematically the electronic and topological properties of (LaXO3)3/(LaAlO3)3(111) superlattices with X = Ti, Mn and Co, where a LaAlO3 trilayer spacer confines the LaXO3 (LXO) dice lattice. In the absence of spin-orbit coupling (SOC) with symmetry constrained to P3, the ferromagnetic (FM) phase of the LXO(111) trilayers exhibits a half-metallic band structure with multiple Dirac crossings and coupled electron-hole pockets around the Fermi energy. Symmetry lowering induces a significant rearrangement of bands and triggers a metal-to-insulator transition. Inclusion of SOC leads to a substantial anomalous Hall conductivity (AHC) around the Fermi energy reaching values up to [Formula: see text] for X = Mn and Co in P3 symmetry and both in- and out-of-plane magnetization directions in the first case and along [001] in the latter. The dice lattice emerges as a promising playground to realise nontrivial topological phases with high Chern numbers.

Abstract
Obesity is an important health problem in our society today, which can lead to the chronic low-grade inflammation state, to be an inducement for many chronic diseases such as hypertension, type 2 diabetes and non-alcoholic fatty liver disease. As a common oral chronic infectious disease, periodontitis is mainly characterized by gingival inflammation, periodontal pocket formation, alveolar bone resorption and tooth mobility. The ultimate goal of periodontitis treatment is to achieve periodontal tissue regeneration in the defect area. As a major risk factor for periodontitis, obesity can alter the periodontal inflammatory microenvironment in multiple ways, affecting the effects of periodontal tissue regeneration ultimately. Therefore, this paper will review the relationship between obesity and periodontal tissue regeneration, mechanism of obesity affecting periodontal tissue regeneration and the therapeutic strategies of periodontal tissue regeneration, providing new ideas for periodontal tissue regeneration treatment in obesity.

Abstract
High-fat diet (HFD)-induced obesity results in bone loss associated with an imbalanced gut microbiota and altered immune status. Probiotics are live microorganisms that are beneficial to the host and are important in maintaining bone health and gut homeostasis. In this study, the probiotic Lactobacillus coryniformis subsp. torquens (T3L) was isolated from traditional yak milk cheese produced in Lhasa and showed distinct acid and bile salt resistance as potential probiotics. Our data indicated that T3L not only reversed HFD-induced gut dysbiosis, as indicated by decreased Firmicutes-to-Bacteroidetes ratios but also reduced bone loss. The anti-obesity, microbiome-modulating, and bone-protective effects were transmissible via horizontal faeces transfer from T3L-treated mice to HFD-fed mice. The protective effects of T3L on bone mass were associated with regulatory T (Treg) cell-mediated inhibition of osteoclast differentiation. Our data indicate that T3L is a regulator of the gut microbiota and bone homeostasis in an animal model.

Abstract
Objective: To establish the norms and clinical application standards of mass spectrometry method to measure vitamin D in capillary blood. Methods: Following the "Province-City-Hospital" sampling procedure, a cross-sectional sample of 1 655 healthy children under 7 years of age were recruited from 12 provinces, autonomous regions, or municipalities in China from November 2020 to December 2021. Both venous and capillary blood samples from the same individual were collected, for which serum 25(OH)D levels were measured by high-performance liquid chromatography-mass spectrometry (HPLC-MS/MS) method. Pearson correlation analysis and linear regression analysis were used to detect the correlation and determine a correction algorithm. The agreement was analyzed using Bland-Altman plot and Kappa statistic. The sensitivity and specificity were evaluated using receiver operating characteristic (ROC) curve method. Results: Venous and capillary 25(OH)D levels of 1 655 healthy children under 7 years of age were 74.25 (59.50, 92.00) and 68.75 (54.44, 86.25) nmol/L, respectively, showed a significant difference(Z=22.14, P<0.001) as well as a highly significant correlation between venous and capillary 25(OH)D levels(r=0.95, P<0.001). Linear regression analysis was then performed to determine the correction algorithm: lg(corrected capillary 25(OH)D)=0.13+0.95×lg(capillary 25(OH)D)(R2=0.90,P<0.001). The deviation between venous and corrected capillary 25(OH)D levels was (0.50±17.50) nmol/L, a difference value that did not reach statistical significance (P>0.05). The cut-off values of capillary blood 25(OH)D values 30.00, 50.00, 75.00 nmol/L corresponding to venous blood 25(OH)D values were 26.59, 45.56, and 69.84 nmol/L, respectively. Good consistency was observed between venous and corrected capillary 25(OH)D levels in clinical diagnosis (Kappa value 0.68-0.81). Corrected capillary 25(OH)D showed a high clinically predictive value (area under curve 0.97-0.99,sensitivity 0.72-0.92,specificity 0.89-0.99). Conclusion: The standardized capillary HPLC-MS/MS method can be used to detect 25(OH)D levels in children clinically.

Abstract
Objective: To investigate the clinicopathological characteristics, immunophenotype, molecular characteristics, differential diagnosis, clinical treatment and prognosis of mixed carcinoma of cervix with adenoid cystic pattern. Methods: Three cases of mixed cervical carcinoma with adenoid cystic pattern were collected at the Affiliated Hospital of Xuzhou University Medical School from 2018 to 2021.The clinicopathological characteristics were analyzed, immunohistochemistry (IHC) and in situ hybridization (ISH) were performed. The related literature was reviewed. Results: The three patients were postmenopausal women with a median age of 74.7 years. The clinical symptom was vaginal bleeding without obvious causes. One case was an endophytic tumor, and the others were exophytic. The median diameter of the three cases was 3.3 cm. Two patients underwent hysterectomy, the tumors infiltrated the external 1/3 and middle 1/3 of the cervix respectively. All the lymph nodes were negative. One patient had a previous biopsy. Microscopically, all three tumors were characterized by a cribriform structure, which were filled with basophilic myxoid substance and surrounded by tubules lined by two layers of cells. The tumor cells had scanty cytoplasm and showed the characteristics of cervical basal-like cells. All three cases were accompanied by high-grade squamous intraepithelial lesions and squamous cell carcinoma, and one also showed a non-specific spindle cell sarcomatoid component. Within the double-layered epithelial structure, the outer epithelium was positive for p63, CD117, p16INK4a (clone E6H4) and MYB protein and negative for S-100 by IHC. The combined positive score of PD-L1 (clone 22C3) was less than 1 in all three cases. Human papillomavirus (HPV) types 16 and 18 were detected in one patient preoperatively, while high-risk HPV were positive in the other two patients by RNAscope ISH postoperatively. None of the three cases showed MYB gene rearrangement by FISH. The mean follow-up time was 23.3 months (36, 28 and 6 months, respectively). Two patients underwent hysterectomy and radiotherapy survived without disease. One patient survived with tumor just by radiotherapy and drug therapy. Conclusions: Mixed cervical carcinoma with adenoid cystic pattern is extremely rare. It is a high-grade malignancy with poor prognosis. The tumor is associated with high-risk HPV infection, without MYB gene rearrangement, and with low PD-L1 immunoreactivity. Radical surgery combined with radiotherapy and chemotherapy is the mainstay of treatment at present.

Abstract
Objective: To study the effects of salivary microbiota in patients with periodontitis on the tryptophan-aryl hydrocarbon receptor (AhR) signaling axis in mice with periodontitis and to provide theoretical basis as well as new ideas for the influences of periodontitis on systemic metabolism. Methods: Salivary microbiota of 12 healthy individuals and 14 patients with periodontitis were collected in Nanjing Stomatological Hospital, Medical School of Nanjing University from June to December of 2020. According to the random number table method, twenty-four mice were randomly divided into three groups: Sham group (control group), P group (periodontitis patients' salivary microbiota group) and H group (periodontal healthy individuals' salivary microbiota group). The maxillary second molars of all mice were treated with silk thread ligation to induce periodontitis. Phosphate buffer as well as salivary microbiota of periodontal healthy individuals and periodontitis patients were gavaged into periodontitis mice for 2 weeks. The expression of inflammatory factors in mice serum were detected by enzyme linked immunosorbent assay, and the expression of tryptophan and indole metabolites in intestinal tract and serum were detected by liquid chromatography-mass spectrometry. The expression of AhR in intestinal tract of mice was detected by immunohistochemistry and quantitative real time-PCR while gut microbiota constitution was detected by 16S rRNA gene sequencing. The remaining saliva samples of periodontitis patients and periodontal healthy individuals were applied to detect the expression of tryptophan and indole metabolites themselves. Results: The salivary microbiota of periodontitis patients could induce the expression of interleukin-1β [P group: (162.38±39.46) pg/ml, H group: (82.83±20.01) pg/ml; t=4.40, P=0.001) and tumor necrosis factor-α [P group: (361.16±123.90) pg/ml, H group: (191.66±106.87) pg/ml; t=2.54, P=0.030) in serum of periodontitis mice, and reduce the expression of AhR in colon (P group: 1.18±0.05, H group:1.83±0.47; t=3.09, P=0.015) and ileum (P group: 0.80±0.13, H group: 1.18±0.11; t=4.93, P=0.001). After gavage of salivary microbiota of periodontitis patients to the mice, tryptophan (P group: (18.1±3.8)×107, H group: (26.6±6.6)×107; t=2.49, P=0.037] and indole lactic acid [P group: (1.9±0.7)×107, H group: (3.7±0.6)×107; t=4.49, P=0.002) in serum of periodontitis mice were significantly decreased, but was relatively disorder in intestinal tract. However, the expressions of tryptophan and indole metabolites in saliva of periodontitis patients were higher than those of periodontal healthy individuals. There were significant differences in indole propionic acid [P group: (1 239.39±818.72) nmol/L, H group: (56.96±38.33) nmol/L; t=2.83, P=0.022]. What we find noteworthy was that the expressions of indolelactic acid metabolism in saliva, serum and intestinal were consistent, and salivary microbiota of periodontitis patients could reduce the relative abundance of indolelactic acid-producing bacteria in the gut, suggesting that the salivary microbiota of periodontitis patients might affect the expression of AhR through gut microbiota disorder and indolelactic acid downregulation. Conclusions: Salivary microbiota in patients with periodontitis may affect the systemic inflammatory state through down-regulating the expression of tryptophan-AhR signal axis.

Abstract
Prediabetes mellitus (Pre-DM) is an intermediate state of hyperglycemia between normal blood glucose homeostasis and type 2 diabetes mellitus (T2DM). More than half of adults in China suffer from Pre-DM. Periodontitis is a chronic inflammatory disease mainly caused by microorganisms in dental plaque. It shares common risk factors and interacts with non-communicable diseases such as diabetes mellitus. Pre-DM may increase the risk of periodontitis, and the latter may also influence the development and progress of diabetes. Oxidative stress, systemic inflammation and intestinal flora are the main mechanisms by which Pre-DM and periodontitis interconnect with each other. This article mainly reviews the relationship between Pre-DM and periodontitis and potential related mechanisms, providing a new basis for the prevention and treatment of both.

Abstract
Objective: To explore current vitamin D status and influential factors of vitamin D deficiency and insufficiency among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China. Methods: According to the "province-city-hospital" sampling technical route, a total of 1 531 healthy children under 7 years of age were sampled from 11 provinces, autonomous regions or municipalities in China by the cluster random sampling method from November 2020 to November 2021. The demographic information, family conditions, behavior and living habits and feeding behaviors were collected using unified questionnaire. Serum 25-hydroxyvitamin D(25(OH)D) levels were measured by liquid chromatography-tandem mass spectrometry. Serum 25(OH)D<30 nmol/L was considered deficient and 30-50 nmol/L was considered insufficient. With 25(OH)D≤50 nmol/L as the dependent variable, multivariate Logistic regression was applied to analyze the association between vitamin D deficiency and insufficiency and potential influential factors. Results: The prevalence of vitamin D deficiency and insufficiency among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China was 14.0% (215/1 531), 3.8% (25/664) and 21.9% (190/867) in 0-<3 and 3-<7 of age years, respectively. Compared to children aged 0-<3 years, children aged 3-<7 years had a 2.6-fold increased risk of vitamin D deficiency and insufficiency (OR=3.60, 95%CI 1.93-6.72, P<0.001). Frequent sunlight exposure (OR=0.46, 95%CI 0.29-0.73, P=0.001), vitamin D supplementation (sometimes, OR=0.33, 95%CI 0.21-0.51, P<0.001; daily, OR=0.20, 95%CI 0.11-0.36, P<0.001) and infant formula intake(4-7 times per weeks, OR=0.43, 95%CI 0.28-0.68, P<0.001) were protective factors for vitamin D deficiency and insufficiency. Conclusion: Vitamin D deficiency and insufficiency are common among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China, which is affected by age, sunlight exposure, vitamin D supplementation and infant formula intake.

Abstract
It is known that intracellular pathogens interact and react with the cellular immune system through exosomes produced by macrophages. This study aimed to determine whether co-culture of macrophages and Talaromyces marneffei induces exosomes and leads to immune responses. T. marneffei was incubated to collect conidia, co-cultured with human macrophages, which then induced exosomes. In cellular experiments, after extraction and purification, the exosomes were then observed by electron microscopy and detected by flow cytometry and mass spectrometry. In animal experiments, flow cytometry and enzyme-linked immunosorbent assay were used to examine whether exosomes were antigenpresenting. The results showed that purified exosomes produced a pro-inflammatory response and stimulated production of TNF-α in non-fungal-treated macrophages. Protein mass spectrometry analysis of exosomes also indicated their potential ability to activate the internal immune response system and the pro-inflammatory response. Translation and ribosomes were the most abundant GO terms in proteins, and the most relevant KEGG pathway was the biosynthesis of secondary metabolites. Furthermore, in vivo experiments revealed that exosomes induced activation of lymphocytes and increased expression of TNF-α and IL-12 in the lung, mediastinum, and spleen area. In conclusion, exosomes can be released by co-culture of T. marneffei and macrophages, having antigen-presenting functions, promoting macrophage inflammation, and initiating adaptive immune responses. These processes are inextricably linked to the translation of secondary metabolites, ribosomes and biosynthesis.

Abstract
Objective: To prepare the modified hyaluronic acid viscous hydrogel loaded with sliver particles and to explore the roles and mechanism of the hydrogel in healing of full-thickness skin defect wounds with bacterial colonization in mice. Methods: The experimental research method was adopted. Dopamine modified hyaluronic acid (HA-DA) and phenylboric acid modified hyaluronic acid (HA-PBA) were prepared, and their characteristic peaks were detected by Fourier-transform infrared spectroscopy. Different mass of acrylamides was added to HA-DA and HA-PBA to prepare the viscous hydrogel with mass fraction of acrylamide in 10%, 15%, and 20%. The gelation of the viscous hydrogel with mass fraction of acrylamide in 20% was observed in the state of tilt and inversion at 37 ℃, and the storage modulus and loss modulus of the above 3 kinds of viscous hydrogels were detected by rotational rheometer. The sliver-loaded viscous hydrogel was prepared by adding nano silver ions to the viscous hydrogel with mass fraction of acrylamide in 20%. The concentration of silver ions released by sliver-loaded viscous hydrogel was measured by inductively coupled plasma mass spectrometer, and the cumulative release rate of silver ion was calculated (n=5). The mouse fibroblasts L929 were divided into phosphate buffered saline (PBS) group, viscous hydrogel group, and sliver-loaded viscous hydrogel group, which were dealt correspondingly, and the cell survival was detected by cell counting kit 8 method after 1, 2, and 3 d of culture (n=5). Twenty-four male C57BL/6 mice aged 6-8 weeks were selected, and forty-eight full-thickness skin defect wounds were inflicted and inoculated with the mixture of Escherichia coli and Staphylococcus aureus in the back of the mice, with two wounds in each mouse. The wounds were divided into normal saline group, viscous hydrogel group, and sliver-loaded viscous hydrogel group, which were dealt correspondingly, with 16 wounds in each group, and two wounds in each mouse were divided into different groups. On post injury day (PID) 3, 7, 10, and 14, the wound healing was observed and the wound healing rate was calculated. On PID 3, the colony forming units of Escherichia coli and Staphylococcus aureus in wounds were observed and counted. On PID 14, the epithelized epidermal thickness and the optical density of collagen fiber in wounds were observed and analyzed after hematoxylin eosin staining and Masson staining, respectively. On PID 3, 7, and 10, the expressions of tumor necrosis factor α (TNF-α), transforming growth factor β1 (TGF-β1), and vascular endothelial growth factor (VEGF) were detected by immunohistochemistry. The number of wounds in each index detecting at each time point was four. Data were statistically analyzed with analysis of variance for factorial design, one-way analysis of variance, and Bonferroni correction. Results: The characteristic peaks of HA-PBA were detected at the wave numbers of 1 369 and 1 425 cm-1, indicating that phenylboric acid had been successfully grafted on hyaluronic acid, and the characteristic peaks of HA-DA were detected at the wave numbers of 1 516 and 1 431 cm-1, indicating that dopamine had been successfully grafted on hyaluronic acid. The viscous hydrogel with mass fraction of acrylamide in 20% maintained the stable and no-flow condition of gelation in the state of tilt and inversion at 37 ℃. The storage modulus and loss modulus of the viscous hydrogel increased with the increase of acrylamide content, the storage modulus and loss modulus of the 3 kinds of viscous hydrogels had no obvious changes with the increase of the oscillation frequency or time, and the storage modulus of the 3 kinds of acrylamide hydrogels were greater than the loss modulus. The release of silver ion in the sliver-loaded viscous hydrogel lasted for 7 days, and the cumulative release rate of silver ion was up to 65%. After 1, 2, and 3 d of culture, the cell survival rates in sliver-loaded viscous hydrogel group were significantly lower than those in PBS group and viscous hydrogel group (P<0.05 or P<0.01), while after 1 d of culture, the cell survival rate in viscous hydrogel group was significantly lower than that in PBS group (P<0.01). With extension of time after injury, the wounds of mice in the 3 groups shrank gradually. On PID 3, 7, 10, and 14, the wound healing rates in sliver-loaded viscous hydrogel group were (53.0±3.6)%, (75.3±6.9)%, (93.3±1.2)%, and (96.7±0.8)%, which were significantly higher than (21.8±6.4)%, (53.9±8.2)%, (72.0±7.8)%, and (92.5±0.4)% in normal saline group (P<0.01). On PID 3 and 14, the wound healing rates in sliver-loaded viscous hydrogel group were significantly higher than (43.5±2.4)% and (94.1±1.5)% in viscous hydrogel group (P<0.05). On PID 3 and 10, the wound healing rates in viscous hydrogel group were significantly higher than those in normal saline group (P<0.01). On PID 3, the colony forming units of two bacteria in wound of sliver-loaded viscous hydrogel group were significantly less than those in normal saline group and viscous hydrogel group (P<0.01), while the colony forming units of two bacteria in wound of viscous hydrogel group were significantly less than those in normal saline group (P<0.05). On PID 14, the wounds were basically epithelialized and the epidermis was thicker, with collagen protein content being increased significantly and more orderly arranged collagen in sliver-loaded viscous hydrogel group compared with those in the other 2 groups. On PID 14, the epidermal thickness in wounds of sliver-loaded viscous hydrogel group was significantly increased compared with that in the other two groups (P<0.05), and the optical density of collagen fiber was significantly increased compared with those in normal saline group (P<0.05). On PID 3, the expressions of TGF-β1 and VEGF in wounds of sliver-loaded viscous hydrogel group were significantly higher than those in normal saline group (P<0.05 or P<0.01), while the expression of VEGF in wounds of viscous hydrogel group was significantly higher than that in normal saline group (P<0.01). On PID 7, the expression of TGF-β1 in wounds of sliver-loaded viscous hydrogel group was significantly higher than that in the other 2 groups (P<0.01), and the expression of VEGF was significantly higher than that in normal saline group (P<0.01). On PID 10, the expression of TNF-α in wounds of sliver-loaded viscous hydrogel group was significantly lower than that in normal saline group (P<0.05), the expressions of TGF-β1 and VEGF in wounds of sliver-loaded viscous hydrogel group were significantly higher than those in normal saline group (P<0.05 or P<0.01), and the expression of VEGF in wounds of sliver-loaded viscous hydrogel group was significantly higher than that in viscous hydrogel group (P<0.05). Conclusions: The sliver-loaded viscous hydrogel prepared in this study has good stability and elasticity, which can continuously release silver ions and help to accelerate the healing of full-thickness defect wounds with bacterial colonization in mice. Besides, the sliver-loaded viscous hydrogel has low biological toxicity and can promote re-epithelialization, collagen deposition as well as angiogenesis of wounds, which may be related to the infiltration and regression of inflammatory cells.

Abstract
Abstract
Objective
Coronary intravascular imaging allows visualization and characterization of vessel wall. Percutaneous coronary intervention (PCI) using intravascular ultrasound or optical coherence tomography has optimized stent deployment techniques, reduced periprocedural outcomes and reduced long-term major cardiovascular events. We sought to investigate the outcomes of imaging guided to conventional angiography guided PCI with reference to in-hospital mortality, hospital length of stay (LOS) and total hospital charge.
Methods
We performed a retrospective cohort study using data from the 2016–2017 Nationwide Inpatient Sample (NIS) which is the largest collection of inpatient hospitalization data in the United States. Patients admitted with a principal diagnosis of acute coronary syndrome (ACS) who underwent PCI with and without intravascular imaging was determined using the International Classification of Diseases, Tenth revision codes. The primary outcome was inpatient mortality while secondary outcomes are showed in table 1. STATA software was used for the analysis. Multivariate logistic and linear regression models were used to adjust for confounders.
Results
There were over 71 million hospital discharges in the combined 2016 and 2017 NIS database. Admission for ACS in adult patients (aged ≥18 years) who underwent PCI yielded 622,855 results. Among this group, 27, 520 (4.4%) had imaging guided PCI while 595,335 (95.6%) had PCI without imaging.
Patients with imaging guided PCI had lower inpatient mortality (3.2% vs 2.3%, AOR: 0.74, 95% CI 0.60–0.90, p=0.004) compared to PCI with angiographic data alone. Imaging guided PCI had an adjusted increased mean LOS of 0.16 days (3.8 vs 3.7 days, CI: 006–0.26, p=0.002) with an adjusted increased mean total hospital charge of $13, 206 ($120,203 vs $104,916, p= <0.0001).
Conclusion
Patients hospitalized for ACS who had imaging guided PCI had reduced inpatient hospital mortality compared to those who had PCI without imaging guidance. Overall utilization of imaging was less than 5% in 2016–2017, however it is expected to be higher in recent years with improvements in clinical practice, training and available scientific evidence.

Abstract
Terahertz (THz) magneto-optical (MO) properties of monolayer (ML) tungsten disulfide (WS2), placed on different substrates and subjected to external magnetic fields, are studied using THz time-domain spectroscopy (TDS). We find that the THz MO conductivity exhibits a nearly linear response in a weak magnetic field, while a distinctly nonlinear/oscillating behavior is found in strong magnetic fields owing to strong substrate-induced random impurity scattering and interactions. The THz MO response of ML WS2 depends sensitively on the choice of the substrates, which we trace back to electronic localization and the impact of the substrates on the Landau level (LL) spectrum. Our results provide an in-depth understanding of the THz MO properties of ML WS2/substrate systems, especially the effect of substrates, which can be utilized to realize atomically thin THz MO nano-devices.

Abstract
Objective: To investigate the relationship of microcystic elongated fragmented (MELF) and clinicopathological features of patients with low grade endometrial endometrioid carcinoma, and to analyze its impact on prognosis. Methods: The clinical pathological data of 512 cases with low grade endometrial endometrioid adenocarcinoma were collected. The MELF invasive pattern in all of the sections were reappraised. The correlations between MELF pattern and clinicopathological features were analyzed by chi-square test, and the independent risk factor of lymph node metastasis were evaluated by Logistic multivariate regression analysis. Survival curves was drawn by Kaplan-Meier method, and Log-rank test was used to compare progression free survival (PFS) between patients with or without MELF pattern. Disease progression-related multivariate analysis was carried out by Cox proportional hazards model. Results: MELF pattern was observed in 12.9% (66/512) low grade endometrioid adenocarcinoma. It was significantly associated with cervical stroma invasion, more than half of the depth of myometrial invasion, lymph node metastasis and vessel invasion (P<0.05). In addition, MELF pattern was an independent risk factor for lymph node metastasis (P<0.05). The 5-year PFS of patients with and without MELF pattern were 95.0% and 96.0% respectively (P>0.05). Conclusions: The patients with MELF pattern are more likely accompany with cervical stroma and deeper myometrium invasion, vessel invasion, and lymph node metastasis, and it is an independent risk factor of lymph node metastasis. However, MELF pattern has no significant impact on prognosis of patients with endometrioid carcinoma.

Abstract
Objective: To study whether high-fat diet could aggravate the effect of periodontitis on gut microbiota and glucose metabolism. Methods: Twenty-four male SD rats were randomly and equally divided into four groups based on table of random numbers (n=6 in each group): control group, in which rats were given normal chow diet; periodontitis group, in which periodontitis was induced by ligating bilateral maxillary second molars with 5-0 silk thread; high-fat diet group, in which rats were given high-fat diet; high-fat diet+periodontitis group, in which rats were given high-fat diet and periodontitis was induced at the end of the 8th week. Fasting blood glucose and glucose tolerance were measured at the end of the 12th week. Then the rats were euthanized and the cecum content was collected. The microbial 16S rRNA gene sequencing was performed on the Illumina MiSeq platform. The taxonomy of the sequences was analyzed through RDP Classifier (http://rdp.cme.msu.edu/) against the SILVA (SSU123) 16S rRNA database. Pearson correlation analysis was performed to analyze the correlation between changes in gut microbiota and blood glucose. Results: After 4 weeks of periodontitis induction, the fasting blood glucose levels of the periodontitis group and the high-fat diet group were (4.93±0.28) and (5.25±0.24) mmol/L, respectively, which were significantly higher than that of the control group [(4.56±0.20) mmol/L] (P<0.05) with glucose intolerance. The fasting blood glucose level of high-fat diet+periodontitis group [(5.53±0.14) mmol/L] was significantly higher than that of periodontitis group and high-fat diet group, respectively (P<0.05), with the glucose tolerance curve higher than that of periodontitis group. The 16S rRNA gene analysis revealed that the Bacteroides/Firmicutes ratio in the periodontitis group is (0.37±0.23), which was significantly lower than that of the control group (0.68±0.05) (P<0.05). The relative abundance of Lachnospiraceae_NK4A136_group in the periodontitis group was (14.03±6.38)%, which was significantly lower than that of the control group [(28.21±4.82)%] (P<0.05). The relative abundance of Allobaculum [(4.27±2.67)%], Ruminococcaceae_UCG_005 [(3.70±0.90)%], Blautia [(0.63±0.45)%] in the periodontitis group were significantly higher than those of the control group [(0.60±0.72) %, (0.43±0.16) %, (0.13±0.13) %, respectively](P<0.05). Compared with periodontitis group, the relative abundance of Proteobacteria in high-fat diet+periodontitis group [(3.06±0.90)%] was significantly higher than that of the periodontitis group [(1.40±0.98)%] (P<0.05). The principal coordinate analysis and similarity analysis based on the Bray-Curtis distance showed that samples of the high-fat diet+periodontitis group clustered separately from the periodontitis group and the high-fat diet group. The results of correlation analysis showed that the abundance of Lachnospiraceae_NK4A136_group was negatively correlated with fasting blood glucose and glucose levels after loading for 60 and 120 minutes (r=-0.56, -0.50, -0.42, respectively) (P<0.05). The abundance of Allobaculum, [Eubacterium]_coprostanoligenes_group, Peptococcaceae_uncultured, [Ruminococcus]_torques_group, and several genera belonging to the Proteobacteria were positively correlated with glucose levels after loading for 120 minutes (P<0.05). Conclusions: Periodontitis might be closely related to impaired gut microbiota and glucose metabolism, and the effect could be aggravated by high-fat diet.

Abstract
Insect samples found on human corpses can provide the information important to estimating the minimum postmortem interval (PMImin). A female cadaver, found in a deserted factory in Chongqing of China, was confirmed as a homicide case after the forensic investigation and autopsy. Determining the time of death was difficult due to the inconsistent degree of decomposition in different parts of the decedent. The insect specimens found on the cadaver were identified to be Chrysomya rufifacies (C. rufifacies, Macquart) by morphology and mitochondrial DNA sequence analysis. The PMImin was estimated to be 452 h, based on the developmental rate of C. rufifacies. The PMImin was estimated successfully to be almost precise, which provided an important entomological evidence for case investigation and suspect prosecution. In so doing, this highlights the usefulness of entomological evidence of specific species in the geographic area for PMI accurate estimation, especially in the case of advanced decomposed corpses.

Abstract
AIM To determine the differences in clinicopathological and mammographic findings between ductal carcinoma in situ (DCIS) and ductal carcinoma in situ with micro-invasion (DCIS-MI) and explore clinicopathological and mammographic factors associated with DCIS-MI. MATERIALS AND METHODS All DCIS patients with or without micro-invasion who underwent preoperative mammography at The Affiliated Hospital of Qingdao University from January 2016 through June 2020 were identified retrospectively. The correlations of clinicopathological findings with DCIS-MI were evaluated using univariate and multivariate binary logistic regression analyses. Imaging findings were compared between the groups by using the Pearson chi-square test. RESULTS A total of 445 DCIS lesions and 151 DCIS-MI lesions were included in the final analysis. Large extent (≥2.7 cm), high nuclear grade, comedo-type, negative progesterone receptor (PR), negative oestrogen receptor (ER), high Ki-67 and axillary lymph node metastasis were more frequently found in DCIS-MI than in DCIS (all p<0.05), and the first four of these were found to be independent predictors of DCIS-MI in the multivariate analysis (all p<0.05). Regarding imaging findings, compared to DCIS, DCIS-MI showed fewer occult lesions and more lesions with calcifications in mass, asymmetry, and architectural distortion (p=0.004). Grouped calcifications were usually associated with DCIS, while regional calcifications were commonly found in DCIS-MI (p<0.05). CONCLUSION Large extent, high nuclear grade, comedo-type and negative PR were found to be independent predictors of DCIS-MI. Lesions with calcifications and regional calcifications were more likely associated with DCIS-MI on mammography.

Abstract
Objective To establish the basic data for estimating minimum postmortem interval (PMImin) of heavily decayed and skeletonized remains by studying the development of Dermestes maculatus DeGeer (Coleoptera: Dermestidae). Methods The developmental stages of Dermestes maculatus were observed at four constant temperatures of 20 ℃, 24 ℃, 28 ℃ and 32 ℃, and the changes in body length were also examined as the biological indicator to estimate larval day-age and instar. Results The total developmental time from egg to adult at 20 ℃, 24 ℃, 28 ℃ and 32 ℃ were (126.7±10.6) d, (69.4±8.2) d, (50.4±8.4) d and (49.6±6.5) d, respectively. The body length increased gradually, but changed irregularly as a whole. Conclusion The study provides basic data on the development and growth of Dermestes maculatus, especially on its developmental duration as a significant value for estimating PMImin of heavily decayed and skeletonized remains. Nevertheless, the change of body length is not found to be the best biological indicator for instar determination.

Abstract
Microplastics (MPs), plastics with particles smaller than 5 mm, have been found almost in every corner of the world, especially in the ocean. Due to the small size, MPs can be ingested by animals and enter the marine trophic chain. MPs can affect animal health by physically causing damage to the digestive tract, leaking plastic chemical components, and carrying environmental pollutants and pathogens into animals. In this study, impacts of MPs ingestion on gut microbiota were investigated. Filter feeding mussels were exposed to "virgin" and "weathered" MPs at relatively realistic concentration 0.2 mg L-1 ("low") and exaggerated concentration 20 mg L-1 ("high") for 6 weeks. Influence in mussel gut microbiota was investigated with 16S rRNA gene high-throughput sequencing. As compared with non-exposed mussels, alteration of gut microbiota was observed after mussels were exposed to MPs for 1 week, 3 weeks, 6 weeks, and even after 8-day post-exposure depuration. Potential human pathogens were found among operational taxonomic units (OTUs) with increased abundance induced by MP-exposure. Faecal pellets containing microorganisms from altered gut microbiota and MPs might further influence microbiota of surrounding environment. Our results have demonstrated impacts of MP-exposure on mussel gut microbiota and suggested possible consequent effects on food quality, food safety, and the well-being of marine food web in the ecosystem for future studies.

Abstract
Objective: To quantitatively evaluate the change of the long axis angle and the relative displacement of the crown feature points of the posterior teeth under normal bite force utilizing an intraoral scanner, and to provide clinical reference. Methods: From May to December 2019, fifteen graduate volunteers (5 males and 10 females, aged from 22 to 30, with an average age of 25.7 years) from Peking University School and Hospital of Stomatology were recruited to participate in the study. The surface data (U1, L1) of the maxillary and mandibular posterior teeth were scanned by an intraoral scanner i500, and saved as original data. The volunteers were guided to bite in the intercuspal position with normal bite force. The buccal bite data of the posterior teeth were scanned as the basis for registration. The digital casts were imported into Geomagic studio 2013 software and the boundary lines along the gingival margin and mesial and distal contact area of posterior teeth of data (U1, L1) were determined. Long axis of the crown, crown centroid and mesial functional cusp vertex were establishd. The data (U1, L1) were segmented into single tooth. Single tooth was aligned to buccal bite data separately using best-fit alignment command based on the buccal common area of the crown and new casts data (U2, L2) were obtained as the data under bite force. The long axis angle and centroid distance between adjacent teeth (second premolar and first molar, second molar and first molar) were measured and the deviation between data obtained at mouth-open state and that at biting state was calculated. Negative value meant centroid distance became shorter under bite force. The first molar was set as the common area and registrate the U1, L1 to U2, L2. The angle of long axes, and displacement of centroid and of functional cusp vertex between second premolar of two casts were calculated, as well as between second molar of two casts. Wilcoxon signed rank test was used to analyze the differences of teeth displacement between second premolar and second molar, and between maxillary and mandibular jaws with SPSS 26.0 statistical software. Results: The result of second premolar and second molar in the same jaw had no statistical difference (P>0.05). The centroid distance deviation of mandibular second premolar-first molar [-0.022(0.046) mm] was larger than that of maxilla [-0.006 (0.040) mm] (P<0.05). The long axis angle of second premolar itself [0.913°(0.647°)] and centroid distance of second molar itself [0.102 (0.106) mm] on the mandibular jaw were different from that on the maxillary jaw, which were 0.590°(0.550°) and 0.074(0.060) mm respectively (P<0.05). Conclusions: Under bite force, displacement of the second premolar and second molar was present, including the displacement of centroids and deflection of long axes. The mandibular posterior teeth have larger displacement than the maxillary teeth.

Abstract
Objective: To compare the subgingival microbiota of subjects from patients with aggressive periodontitis (AgP), chronic periodontitis (CP) and periodontally healthy (PH) individuals, respectively. Methods: Volunteers were recruited from the Nangjing Stomatological Hospital, Medical School of Nanjing University during December 2013 to December 2014. Ten individuals were included in each of three groups. Preliminary estimation of sampling sites was chosen based on the X-ray and intraoral examination. Then the subgingival plaque samples were collected, the periodontal clinical indices were recorded, genes were extracted and amplified by PCR, and subsequently a DNA library was constructed for 16S rDNA sequencing. The library that can be successfully constructed and sequenced includes: 18 samples from 8 AgP group patients, 31 samples from 10 CP group patients and 10 samples from 8 PH group volunteers. Finally, we analyzed and compared the α-diversity, β-diversity and microbial compositions of samples in each group. Pearson correlation analysis was adopted to evaluate the correlation between the relative abundance of microorganisms and the probing depth (PD). Results: The α-diversity of subgingival flora in AgP group was significantly lower than that in PH group and CP group, respectively (P<0.05). On the phylum level, the abundance of Bacteroides [(36.8±7.4)%] and Spirochetes [(16.0±5.4)%] in AgP group and the abundance of Bacteroides [(37.2±6.3)%] and Spirochetes [(11.8±3.6)%] in CP group were significantly higher than those in PH group [(27.5±11.2)%, (5.2±4.4)%, respectively, P<0.05]. While the relative abundance of Actinomycetes and Proteobacteria [(4.2±3.3)%, (12.9±5.1)%, respectively] in AgP group and that of CP group [(6.1±2.6)%, (12.1±4.0)%, respectively] were significantly higher than PH group [(19.3±13.1)%, (23.0±10.1)%, respectively, P<0.01). The abundance of Spirochetes and Tenericutes in AgP group [(16.0±5.4)%, (1.7±1.2)%, respectively] were significantly higher than that in CP group [(11.8±3.6)%, (0.7±0.6)%, respectively, P<0.05]. At the genus level, Corynebacterium, Actinomycete, Saccharibacteria_norank, Selenomonas and Oribacterium in the subgingival flora of AgP group were significantly lower than that of CP group, while the relative abundance of Actinomycetes, Lentimicrobiaceae_norank, Defluvitaleaceae_UCG_011, Family_XI_unclassified were significantly higher than that of CP group (P<0.05). Principal coordinate analysis showed that samples of each group clustered separately from each other. Linear discriminant analysis revealed that the bacteria enriched in AgP group included Spirochetes, while in CP group included Bacteroidaceae. The result of correlation analysis showed that the abundance of the following genera in AgP group were positively correlated with PD: Treponema_2, Defluitaleaceaeae_UCG_011, Mycoplasma, Catonella, Fretibacterium (r=0.525-0.750, P<0.05). While the relative abundance of Comamonadaceae_unclassified, Streptococcus, Capnocytophaga, Neisseria, Prevotella, Peptococcus, Ralstonia, Bergenia and Actinomycetes were negatively associated with PD (r=-0.617--0.490, P<0.05). In the CP group, the abundance of Dialister, Family_XI_unclassified, Catonella, Peptococcus, Pelospora and Rikenella_RC9_gut group were positively correlated with PD (r=0.430-0.533, P<0.05). Conclusions: There is a clear difference between the subgingival flora of periodontal patients and that of PH individuals. Besides, subgingival flora of AgP and CP are also different, suggesting that these could be two different diseases.

Abstract
The epidemiological history and clinical characteristics of 7 cases of COVID-19 and 1 case of close contact in the first family aggregation epidemic of COVID-19 in Gansu Province were analyzed. The first patient A developed on January 22, 2020, with a history of residence in Wuhan, and confirmed severe cases of NCP on January 24, 2020; patient B, on January 23, 2020, diagnosed on January 31, severe cases; patient C, asymptomatic, diagnosed on January 27; patient D, asymptomatic, diagnosed on January 27; patient E, on January 24, diagnosed on January 28; patient F, asymptomatic, diagnosed on January 31; Patient G was asymptomatic and was diagnosed on January 31. In close contact, H was asymptomatic, PCR test was negative and asymptomatic, and he was discharged early. Among the 7 patients, 1 case died of (B) aggravation, and the other patients' condition was effectively controlled after active treatment. Except for the discharged cases, 5 cases were positive for COVID-19 specific IgM antibody and 1 case was negative. In this clustering outbreak, 4 patients remained asymptomatic, but PCR and IgM antibodies were positive, indicating that asymptomatic patients may be the key point to control the epidemic. Specific IgM antibody screening for patients whose pharyngeal swab nucleic acid test is negative but with ground glass-like lung lesions is very important for early detection and early isolation.

Abstract
OBJECTIVE To examine the effect of rational emotive therapy on negative emotions among advanced schistosomiasis patients with repeated hospitalizations. METHODS A total of 97 advanced schistosomiasis patients with anxiety and depressive emotions that were hospitalized in Xiangyue Hospital of Hunan Institute of Schistosomiasis Control for three times or more were enrolled, and given rational emotive therapy for 4 weeks in addition to routine nursing care. The scores for anxiety, depression and quality of life were estimated in patients before and after the rational emotive therapy using the Self-Rating Anxiety Scale (SRS), the Self-Rating Depression Scale (SDS) and WHOQOL-BREF Form. RESULTS The SAS and SDS scores were significantly lower 4 weeks following rational emotive therapy than before the intervention (SAS score, 45.40 ± 7.77 vs. 59.25 ± 9.29, t = 14.021, P < 0.01; 51.48 ± 8.01 vs. 63.93 ± 9.59, t = 12.991, P < 0.01). The percentages of patients with moderate and severe anxiety and depression were significantly lower 4 weeks following rational emotive therapy than before the intervention (P < 0.01), and the scores for each item in the quality of life were all significantly greater 4 weeks following rational emotive therapy than before the intervention (P < 0.01). CONCLUSIONS Rational emotive therapy may improve the negative emotions and the quality of life of advanced schistosomiasis patients with repeated hospitalizations.

Abstract
Objective: To explore the relationships between serum lipoprotein-associated phospholipase A2 (Lp-PLA2) and KIM-based white matter lesion (WML) and carotid atherosclerotic plaque. Methods: From November 2018 to July 2019, 155 patients admitted to the Department of Neurology of the First Affiliated Hospital of Anhui Medical University were enrolled, with 125 cases of brain MRI manifestations of white matter lesions allocated to WML group and 30 cases of normal MRI in control group (NC group). According to KIM classification, WML patients were further divided into juxtaventricular white matter lesion (JVWML) group (n=30), periventricular white matter lesion (PVWML) group (n=33), juxtacortical white matter lesion (JCWML) group (n=30) and deep white matter lesion (DWML) group (n=32). Clinical Data of vascular risk factors in all subjects was collected and reviewed. Serum Lp-PLA2 content was determined by double-antibody sandwich enzyme-linked immunosorbent assay (ELISA). Carotid atherosclerosis plaques were detected by carotid artery ultrasonography and divided into stable and vulnerable plaques, and thus total score of each plaque was subsequently calculated according to the Crouse method. Results: The Lp-PLA2 ((117±37) ng/ml vs (95±30) ng/ml), stable Crouse plaque integral (CPI) (0 (0,2.5) vs 0) and unstable CPI (0 (0,3.4) vs 0) in the WML group were significantly higher than those in the NC group (all P<0.05). Lp-PLA2 ((138±41) ng/ml) and unstable CPI (1.5(0,3.8)) in the PVWML group were significantly higher than those in the NC group (all P<0.05). Lp-PLA2 levels in the PVWML group were significantly higher than those in the JVWML group ((100±28) ng/ml) and JCWML group ((101±27) ng/ml) (all P<0.05). Correlation analysis revealed that blood glucose (r=0.600, P=0.000), triglyceride (TG) (r=0.371, P=0.034), low-density lipoprotein cholesterol (LDL-C) (r=0.367, P=0.036) and Lp-PLA2 (r=0.567, P=0.001) were positively correlated with unstable CPI in PVWML group, while it is negatively correlated with HDL-C (r=-0.368, P=0.035). Multivariate linear regression of all relevant factors and unstable CPI in the PVWML group showed that blood glucose (b=0.463, P<0.01) and Lp-PLA2 (b=0.347, P<0.05) were still positively correlated with unstable CPI. Conclusions: Serum Lp-PLA2 is an indicator of atherosclerosis, which is associated with carotid instability plaques in periventricular WML, suggesting that inflammatory mechanism plays an important role in the development of ischemic white matter lesions.

Abstract
The present study aimed to evaluate the effects of excess dietary fluoride (F) on laying performance, egg quality, tissue retention, serum biochemical indices, and serum reproductive hormones of laying hens. A total of 384 Hy-Line Gray hens, 37 wk old, were treated with sodium fluoride added to a corn-soybean meal basal diet at 0, 400, 800, and 1200 mg fluorine/kg feed. The results showed that dietary F levels at 800 and 1200 mg/kg markedly decreased ADFI, laying rate, average egg weight, and increased feed conversion ratio (FCR) (P < 0.05). Dietary F levels at 800 and 1200 mg/kg dramatically decreased the egg quality of albumen height, yolk color, eggshell strength, and eggshell thickness, and on the 49th D, 400 mg/kg F group significantly decreased the eggshell strength, compared to those of control group. Fluoride residues in tissues of hens were increased significantly with the increase of dietary F supplemental levels (P < 0.05). Fluoride concentrations were generally high in feces, eggshell, tibia, kidney, and ovary, and the highest in feces, following with eggshell and tibia, lower in kidney and ovary, and the lowest in serum. Serum uric acid levels and alanine aminotransferase activity increased significantly (P < 0.05), and glucose, triglycerides, and phosphorus decreased significantly (P < 0.05) in response to dietary F concentration, compared to those of the control group, respectively. Dietary F supplementation at 1200 mg/kg significantly decreased (P < 0.05) the estrogen concentrations in serum, compared to those of the control group. Concentrations of progesterone in the fluoride-treated groups were significantly (P < 0.05) decreased relative to those of the control group. In conclusion, these results indicated that the excessive ingestion of F has had a detrimental effect on egg laying rate and quality of eggs by damaging the function of the liver, kidney, and ovary of laying hens.

Abstract
Blastocystis is frequently identified in humans and animal hosts and exhibits a large genetic diversity with the identification of 17 subtypes (STs). Despite its zoonotic potential, its prevalence and ST distribution in edible marine fish and marine mammals remain unknown. A large-scale survey was thus conducted by screening 345 fish caught in Atlantic Northeast and 29 marine mammals stranded on the coasts of northern France for the presence of the parasite using real-time Polymerase Chain Reaction PCR. The prevalence of the parasite was about 3.5% in marine fish. These animals were mostly colonized by poikilotherm-derived isolates not identified in humans and corresponding to potential new STs, indicating that fish are natural hosts of Blastocystis. Marine fishes are also carriers of human STs and represent a likely limited source of zoonotic transmission. 13.8% of the marine mammals tested were colonized and 6 different STs were identified including 3 potential new STs. The risk of zoonotic transmission through marine mammals is insignificant due to the lack of repeated contact with humans. The present survey represents the first data regarding the prevalence and ST distribution of Blastocystis in marine fish and marine mammals and provides new insights into its genetic diversity, host range and transmission.

Abstract
BACKGROUND Infantile haemangiomas (IHs) involving the lip are of special concern because of the susceptibility of complications, including ulceration, obstruction and disfigurement. The available data for the relationship between their clinical characteristics and ulcerations are limited. OBJECTIVES To describe the clinical characteristics of lip IHs and to evaluate the main risk factors for ulceration. METHODS A retrospective study was designed that included infants with lip IHs during an 8-year period, the clinical data of participants were collected, and univariable and multivariable logistic models were used to determine the relationships between the clinical characteristics of lip IHs and ulcerations. Location, size and type were investigated as potential independent factors influencing the development of ulceration. RESULTS A total of 69 lip IHs were identified including 40 girls and 29 boys. Ulcerations were found in 37 (53.6%) lip IHs. Lip haemangiomas experiencing ulceration had a mean size (SD) of 3.49 (2.82) cm2 compared with 1.08 (0.96) cm2 for those without ulceration. Twenty-eight (52.8%) of the 53 localized haemangiomas and 9 (56.3%) of the 16 segmental haemangiomas experienced ulcerations. Univariable analyses of all investigated factors revealed significant associations of location and size with increased risk of ulceration, and these significant associations remained after adjusting for sex and age [OR 8.61 (95% CI, 2.24-33.13) and 2.62 (95% CI, 1.46-4.72), respectively]. The duration before ulceration was between 4 and 70 days after the occurrence of lip IHs, with a median of 28 (19.41) days. Most ulcers occurred within 45 days of IH occurrence. CONCLUSIONS Ulceration is a common complication of lip IHs at an earlier stage. A swollen with pale or bright crimson appearance of the lip IH surface could be an important signal of subsequent ulceration. Location of the IH on the lower lip and lip IH size are risk factors for the occurrence of ulceration.

Abstract
The epidemiological history and clinical characteristics of 7 cases of COVID-19 and 1 case of close contact in the first family aggregation epidemic of COVID-19 in Gansu Province were analyzed. The first patient A developed on January 22, 2020, with a history of residence in Wuhan, and confirmed severe cases of NCP on January 24, 2020; patient B, on January 23, 2020, diagnosed on January 31, severe cases; patient C, asymptomatic, diagnosed on January 27; patient D, asymptomatic, diagnosed on January 27; patient E, on January 24, diagnosed on January 28; patient F, asymptomatic, diagnosed on January 31; Patient G was asymptomatic and was diagnosed on January 31. In close contact, H was asymptomatic, PCR test was negative and asymptomatic, and he was discharged early. Among the 7 patients, 1 case died of (B) aggravation, and the other patients' condition was effectively controlled after active treatment. Except for the discharged cases, 5 cases were positive for COVID-19 specific IgM antibody and 1 case was negative. In this clustering outbreak, 4 patients remained asymptomatic, but PCR and IgM antibodies were positive, indicating that asymptomatic patients may be the key point to control the epidemic. Specific IgM antibody screening for patients whose pharyngeal swab nucleic acid test is negative but with ground glass-like lung lesions is very important for early detection and early isolation.

Abstract
Objective: The authors aim to provide genetic counselling and prenatal gene diagnosis to the families with osteogenesis imperfecta(OI), based on the identification of pathogenetic mutations in large cohort genetic testing. Methods: DNA was extracted from the peripheral blood of parents of the fetuses, and from the villi tissue, amniotic fluid or cord blood of the fetuses using a standard sodium dodecyl sulfate-proteinase K-phenol/chloroform extraction method. PCR combined with Sanger DNA sequencing was performed to validate the pathogenic mutations of 200 fetuses at risk of OI and their parents from 158 families. Allelic analysis of microsatellite markers was applied to exclude the false positive caused by maternal DNA contamination, when both the fetus and the mother harbored the same pathogenic genotype. Results: A total of 83 affected fetuses (83/200, 41.5%) and 12 (12/200, 6.0%) recessive carriers were identified among the 200 fetuses. The 83 affected fetuses included 78 heterozygotes (45 of COL1A1, 32 of COL1A2, one of IFITM5), and 5 compound heterozygotes or homozygotes of recessive OI (two of FKBP10, one of SEC24D, one of WNT1 and one of CRTAP); The 12 recessive carriers included 7 of WNT1, 4 of SERPINF1 and one of SERPINH1. Maternal DNA contamination was excluded from the genomic DNA samples of OI fetuses when their mother with the same affected genotypes. Conclusion: In this study, the authors used an optimized gene diagnosis system of OI to perform prenatal genetic diagnosis to 200 fetuses at high risk of OI, and provided precisely genetic counselling to the OI families.

Abstract
Atomic vacancies and nanopores act as local scattering centers and modify the transport properties of charge carriers in phosphorene nanoribbons (PNRs). We investigate the influence of such atomic defects on the electronic transport of multi-terminal PNR. We use the non-equilibrium Green's function approach within the tight-binding framework to calculate the transmission coefficient and the conductance. Terminals induce band mixing resulting in oscillations in the conductance. In the presence of atomic vacancies and nanopores the conductance between non-axial terminals exhibit constructive scattering, which is in contrast to mono-axial two-terminal systems where the conductance exhibits destructive scattering. This can be understood from the spatial local density of states of the transport modes in the system. Our results provide fundamental insights into the electronic transport in PNR-based multi-terminal systems and into the ability of atomic defects and nanopores through tuning the transport properties.

Abstract
OBJECTIVE To analyze the endemic situation of schistosomiasis in Wuhu City from 2009 to 2018, so as to provide evidence for adjusting and developing the control strategy. METHODS The data regarding the endemic situation were retrospectively collected and analyzed in Wuhu City from 2009 to 2018. RESULTS The prevalence of human Schistosoma japonicum infections reduced from 0.450% in 2009 to 0.035% in 2018 in Wuhu City, and a reduction rate of 92.22% (χ2 = 1 6128.307, P < 0.01), and the prevalence of S. japonicum infections decreased from 0.483% in 2009 to 0 in 2018 (χ2 = 27.570, P < 0.01) in livestock. The area of snail habitats increased from 1 501.07 hm2 in 2009 to 4 408.62 hm2 in 2018, with an increase of 193.70%. No infected snails were found in Wuhu City since 2012, and no egg positives were detected in humans and livestock since 2016. CONCLUSIONS Currently, the endemic situation of schistosomiasis is at a low level in Wuhu City; however, there are still factors affecting schistosomiasis transmission. In the future, the integrated strategy with emphasis on the control of infectious source and the surveillance-response system should be intensified to consolidate the achievements of schistosomiasis control.

Abstract
Objective: To understand the mechanism of chemotherapy resistance in nasopharyngeal carcinoma under hypoxic conditions through the perspective of protein SUMOylation modification. Methods: Cobalt chloride (CoCl(2)) was used to establish the hypoxic model of human nasopharyngeal carcinoma CNE1 cells. Then, the cell cycle was detected by flow cytometry, and the expression level of small ubiquitin-related modifier(SUMO) and cyclin-dependent kinase 6 (CDK6) proteins were detected by western blotting. MTT assay was used to determine the median lethal dose (IC(50)) of cancer cells against cisplatin, and enzyme-linked immunosorbent assay (ELISA) was used to determine lactate dehydrogenase (LDH) level. Results: The cell cycle of CNE1 induced by hypoxia was arrested in G0/G1 phase.The results of Western blot showed that the protein expression level of CDK6 in CNE1 cells was lower than that in the control group (0.83±0.25 vs. 0.43±0.21, t=14.67, P=0.003). The protein level of conjugated SUMO1 was significantly lower than that in the control group (2.69±0.48 vs. 1.38±0.31, t=17.22, P=0.001), while the level of free SUMO1 protein was significantly higher than that in the control group (2.01±0.43 vs. 2.60±0.59, t=15.45, P=0.002).The LC50 of CNE1 cells in the control group was significantly lower than that in the hypoxic group (29.44 μg/ml vs. 97.72 μg/ml, t=12.79, P=0.001). After CNE1 cells received 50 μg/ml cisplatin for 48 h, the LDH content in the supernatant of the control group was significantly higher than that in the hypoxic group ((541.49±64.59) ng/ml vs. (234.67±41.03) ng/ml, t=11.94, P=0.007)). The apoptosis rate of CNE1 cells in the control group was significantly higher than that in the hypoxic group ((76.64±5.37)% vs. (32.84±4.77) ng/ml, t=8.49, P=0.003)). Conclusion: Hypoxia can dissociate the covalent modification of CDK6 and SUMO1, inhibit cell cycle and increase the chemotherapy resistance of nasopharyngeal carcinoma.

Abstract
Food impaction with tight proximal contacts, also known as kinetic food impaction and food impaction without anatomical structure destruction, is mainly caused by a transient separation in contacts area during mastication. It's an intractable food impaction with high morbidity and low cure rate. There are two kinds of pathogenesis accepted: the shifting of anterior teeth incongruous with adjacent teeth or lack of anterior shifting; lack of food escape grooves. The preferred treatment is occlusal adjustment, but it's difficult to determine the area and extent of selective grinding, to quantify the occlusal adjustment, or to predict the prognosis. This review summarized the pathogenesis and treatment modality for kinetic food impaction in order to provide evidence for future researches and clinical application.

Abstract
This experiment was conducted to evaluate the effects of dietary supplementation with Clostridium butyricum on laying performance, egg quality, serum parameters, and cecal microflora of laying hens in the late phase of production. Jinghong-1 strain laying hens (n = 960; 48 wk of age) were randomly allocated to 5 treatment groups with 6 replicates of 32 hens. Hens were fed with basal diet (control) and basal diet supplemented with 2.5 × 104 (CB1), 5 × 104 (CB2), 1 × 105 (CB3), and 2 × 105 (CB4) cfu/g C. butyricum for 10 wk. The results showed that egg production, egg mass, and eggshell strength increased quadratically as supplemental C. butyricum increased, and these responses were maximized in the CB2 group (P < 0.05). Compared with the control group, the addition of C. butyricum resulted in quadratic effects on serum total protein, uric acid, calcium, complement component C3 and catalase concentrations, and these responses were maximized or minimized in the CB2 group (P < 0.05). Linear and quadratic increases were observed in serum IgM, total superoxide dismutase, and glutathione peroxidase concentrations, and these responses were maximized in CB2 or CB3 group (P < 0.05). The addition of C. butyricum in the CB2 group resulted in linearly increasing levels of serum IgG concentration as compared with the control group (P < 0.05). Spleen index increased (P < 0.05) in the CB2 group. Hens fed with C. butyricum reduced (P > 0.05) the population of E. coli, while Bifidobacterium counts increased quadratically and maximized in the CB2 group (P < 0.05). In conclusion, the results indicated that dietary supplementation with C. butyricum (5 × 104 or 1 × 105 cfu/g) could improve laying performance and egg quality by promoting immune function, enhancing antioxidative capacity, and benefiting the cecal microflora of laying hens in the late phase of production.

Abstract
OBJECTIVES To analyze the forensic characteristics of 24 psychiatric patients who died of long-term use of psychotropic drugs. METHODS Cases of sudden death of psychiatric patients from 2011 to 2016 were collected. The forensic characteristics of these sudden deaths were retrospectively analyzed by systematic investigation plus results of autopsy and toxics (drugs). RESULTS Among the 24 psychiatric patients who died of long-term use of psychotropic substances, the ratio of male to female was 1.7∶1, and the average age was (59.0±8.8) years. Fifteen patients had clear disease durations (14.4±8.2) years, and other the nine were known to have disease durations of over 3 years. The death time of 62.5% of patients was the daytime in working days, and 91.7% of the patients died at home. Most patients complained different degrees of physical discomfort before death. Patients with schizophrenia (20 cases) were the most common, followed by depression (4 cases). All patients had the history of taking psychotropic drugs, with clozapine and chlorpromazine being the mostly detected ones. The causes of death were mainly circulatory diseases (15 cases), with the most common being myocarditis (11 cases) followed by pneumonia (4 cases). CONCLUSIONS Critical attention should be paid to the risk of antipsychotics-induced sudden unexpected deaths for psychiatric patients, particularly for those with schizophrenia.

Abstract
Objective: To analyze the interpretation results on the pathogenic classification of KCNH2 variants and SCN5A variants of long QT syndrome (LQTS) based on American College of Medical Genetics and Genomics (ACMG) guidelines by 4 clinical gene screening agencies from Beijing. Methods: Pathogenic classification of 16 variants in KCNH2 and SCN5A was made by 4 clinical gene screening agencies from Beijing based on ACMG guideline. Krippendorff's alpha was used to assess the inter-agency variation consistency. Results: All 4 agencies made pathogenic assessment on all the variants and provided the interpretation results for the classification. For the eight variants from the patients with LQTS, the consistency of classification was only 1/8 and the alpha test value was - 0.01. For the eight variables from incidental findings, the consistency of classification was 4/8 and the alpha test value was 0.407. Evidence analysis of the 4 variants with large differences in classification among agencies showed that the main reasons for the discrepancies originated from the comprehensiveness of the literature search and the inconsistency of the subjective determination of the evidence grade. Conclusion: The consistency of the pathogenic classification of LQTS gene variants based on ACMG guidelines among clinical gene screening agencies from Beijing is poor, which will result in great impact on the clinical treatment strategies of the patients with LQTS. The standardization of pathogenic evaluation of variants in clinical gene screening agencies needs to be improved urgently.

Methods: One hundred and eighty patients, age ranged from 40 to 65 years, body mass index from 18 to 25 kg/m(2,) ASA physical status Ⅱ-Ⅲ, who were scheduled for transcatheter arterial chemoembolization (TACE) under monitor anesthesia care (MAC) were randomly divided into 3 groups: hydromorphone group (H group), hydromorphone supplement with dexmedetomidine 1 μg/kg group (D1 group), hydromorphone supplement with dexmedetomidine 2 μg/kg group (D2 group), 60 patients in every group. All the groups of patients received PCIA pump, in the H group, the PCIA reagent was composed of 120 μg/kg hydromorphone and 5 mg tropisetron in 100 ml of normal saline. In comparison, PCIA regiment was composed of 120 μg/kg hydromorphone, 1 μg/kg dexmedetomidine and 5 mg tropisetron in 100 ml of normal saline in the D1 group, while 120 μg/kg hydromorphone, 2 μg/kg dexmedetomidine and 5 mg tropisetron in 100 ml of normal saline in the D2 group. The visual analogue scale (VAS) score, the observer's assessment of alertness/sedation scale (OAA/S) score, patients' satisfaction index, consumption of hydromorphone, the additional dose of morphine, the effective pressing times of PCIA and adverse reactions were recorded in detail at 0, 0.5, 1, 4, 12 and 24 hours after the patients underwent TACE. Results: The total consumptions of hydromorphone were (4.3±0.1), (4.1±0.1), and (3.8±0.1) mg in group H, D1, and D2, respectively, and the effective pressing times were 13±3, 6±2 and 2±1, the additional doses of morphine were (30±5), (15±3), and (3±1) mg, and adverse reaction rates were 45.0%, 28.3%, and 10.0%, respectively. The manifestations mentioned above in D2 group were significantly lower than those in group H and group D1 (P<0.05). Immediately and 5 min after embolization, at the end of surgery and 0.5, 1, 4, 12 and 24 h after surgery, the VAS scores in the D2 group were 1.9±0.2, 2.1±0.3, 1.8±0.4, 1.8±0.3, 1.7±0.3, 1.6±0.3, 1.3±0.2, 1.3±0.3, respectively, lower than those in group H and group D1 (P<0.05); The satisfaction index in D2 group at these times were 8.7±1.1, 8.9±0.8, 9.2±0.9, 9.0±0.7, 9.1±0.8, 9.0±0.6, 9.1±0.7, 9.2±0.9, respectively, higher than those in group H and group D1 (P<0.05). No breath depression happened in these three groups. Conclusion: The formula of hydromorphone combined with dexmedetomidine to patients undergoing TACE is greatly safe and efficient, with advantages in alleviating pain, reducing hydromorphone consumption and the incidence of adverse reaction of hydromorphone, and without breath depression.

Abstract
Dehydroepiandrosterone (DHEA) possesses fat-reducing effect, while little information is available on whether DHEA regulates cell proliferation and mitochondrial function, which would, in turn, affect lipid droplet accumulation in the broiler. In the present study, the lipid droplet accumulation, cell proliferation, cell cycle and mitochondrial membrane potential were analysis in primary chicken hepatocytes after DHEA treated. The results showed that total area and counts of lipid droplets were significantly decreased in hepatocytes treated with DHEA. The cell viability was significantly increased, while cell proliferation was significantly inhibited in a dose dependent manner in primary chicken hepatocytes after DHEA treated. DHEA treatment significantly increased the cell population in S phase and decreased the population in G2/M in primary chicken hepatocytes. Meanwhile, the cyclin A and cyclin-dependent kinases 2 (CDK2) mRNA abundance were significantly decreased in hepatocytes after DHEA treated. No significant differences were observed in the number of mitochondria, while the mitochondrial membrane permeability and succinate dehydrogenase (SDH) activity were significantly increased in hepatocytes after DHEA treated. In conclusion, our results demonstrated that DHEA reduced lipid droplet accumulation by inhibiting hepatocytes proliferation and enhancing mitochondrial function in primary chicken hepatocytes.

Abstract
This study was conducted to investigate the effects of dietary manganese-methionine (Mn-Met) supplementation on the egg quality of laying hens. A total of 480 Jinghong-1 strain layers aged 53 wk were divided into 5 groups with 6 replicates of 16 layers. Birds in the control group were fed a diet supplemented with 60 mg Mn/kg in the form of MnSO4; the birds in other 4 experimental groups were fed a diet supplemented with 20, 40, 60, and 80 mg Mn/kg as Mn-Met, respectively. Dietary Mn-Met treatments significantly affected (P < 0.05) the albumen height, yolk color, and Haugh unit compared to those of the control diet. The Mn contents in the eggshell increased (P < 0.01) significantly by increasing the Mn-Met supplementation, whereas Mn content in eggshell was triple that in the yolk or albumen. Compared with the 60 mg/kg Mn-Met group, the transverse surface in the control group had (P < 0.01) a greater width of mammillary cones, and there were obvious cracks on the outer surface in the control. There was no difference (P > 0.05) in the eggshell gland (ESG) in the expression of calbindin-D28k (CaBP-D28k) mRNA in response to any diet treatment. In conclusion, dietary Mn-Met supplementation increased internal egg quality and the ultrastructure of the eggshell. Compared to the control, 60 mg/kg Mn-Met treatment resulted in improving egg quality, and 20 mg/kg Mn-Met treatment had similar effects the control treatment had on the egg quality. This indicates that the inorganic Mn can be replaced by the lower concentration of Mn-Met.

Abstract
Metabolic disorder is a major health problem and is associated with a number of metabolic diseases. Due to native hyperglycaemia and resistance to exogenous insulin, chickens as a model had used in the studies of adipose tissue biology, metabolism and obesity. But no detailed information is available about the comprehensive changes of serum metabolites at different stages of chicken embryonic development. This study employed LC/MS-QTOF to determine the changes of major functional metabolites at incubation day 14 (E14d), 19 (E19d) and hatching day 1 (H1d), and the associated pathways of differential metabolites during chicken embryonic development were analysed using Metabolite Set Enrichment Analysis method. Results showed that 39 metabolites were significantly changed from E14d to E19d and 68 metabolites were significantly altered from E19d to H1d in chicken embryos. Protein synthesis was promoted by increasing the concentrations of L-glutamine and threonine, and gonadal development was promoted through increasing oestrone content from E14d to E19d in chicken embryos, which indicated that serum glutamine, threonine and oestrone contents may be considered as the candidate indicators for assessment of early embryonic development. 2-oxoglutaric acid mainly contributed to enhancing the citric cycle, and it plays an important role in improving the growth of chicken embryos at the late development; the decreasing of L-glutamine, L-isoleucine and L-leucine contents from E19d to H1d in chicken embryonic development implied their possible functions as the feed additive during early posthatch period of broiler chickens to satisfy the growth. These results provided insights into understand the roles of serum metabolites at different developmental stages of chicken embryos, it also provides available information for chicken as a model to study metabolic disease or human obesity.

Abstract
Objective:To investigate the clinical effect of local combined with systemic glucocorticoid injection on young and middle-aged patients with severe and profound hearing loss. Method:Ninety-three cases of young and middle-aged patients with severe and profound hearing loss admitted to our hospital from May 2013 to May 2017 were retrospectively analyzed. Patients were divided into two groups according to the different treatment. Forty-six cases in control group were treated with systemic injection of glucocorticoids.Forty-seven cases in observation group were treated with local administration combined with systemic glucocorticoid therapy. The efficacy, changes of average hearing threshold and the incidence of adverse reactions were evaluated.Result:The total effective rate in the observation group was 68.09%, which was significantly higher than that in the control group (45.65%,P<0.05).After treatment, the average hearing thresholds in the observation groups of 0.5,1.0,2.0 and 4.0kHz were(35.77±13.28)dB HL,(39.71±14.09)dB HL, (32.99±10.73)dB HL and (30.17±9.29)dB HL respectively,which were significantly higher than that in the control group(26.30±14.03)dB HL,(25.14±13.28)dB HL,(20.54±9.27)dB HL,and (20.98±8.71)dB HL(P<0.05).Among all the patients received systemic injection of dexamethasone sodium phosphate injection,there was no other complications were found except for one patient whose blood pressure instability was relieved after treatment stopping. In the observation group, intratympanic methylprednisolone sodium succinate did not cause serious complications such as tympanic cavity infection and perforation of the tympanic membrane on the basis of systemic injection.While in the observation group,one case complained of earache and one case complained of a slight burning sensation in the ear, and both of them eased after rest.Conclusion:Local combined with systemic glucocorticoid treatment of young and middle-aged patients with severe and profound hearing loss can significantly improve the efficiency and increase the average hearing threshold changes at 0.5,1.0,2.0 and 4.0 kHz,and there was no serious adverse reactions.
