Abstract
Objective: To assess the impact of Friday surgery on clinical outcomes in elderly patients with hip fracture under multidisciplinary treatment. Methods: A retrospective cohort study. The clinical data of 414 geriatric patients with hip fractures admitted to Zhongda Hospital Affiliated with Southeast University from January 2018 to March 2021 were analyzed retrospectively, including 126 males and 288 females with a mean age of (81.3±7.6) years. The patients were divided into two groups based on whether they underwent surgery on Friday or not. The Friday group(n=69) and the non-Friday group(n=345) were compared in terms of general information, American Society of Anesthesiologists(ASA) classification, fracture type, injury to admission time, preoperative waiting time, surgical method, anesthesia type and use of intensive care unit (ICU) fast track. Propensity score matching (PSM) was performed based on age, ASA grade, time from injury to admission, preoperative waiting time, hemoglobin and albumin levels at admission. Clinical outcomes were collected and compared between the two groups, including length of hospital stay, total hospitalization cost and 30-day, 90-day and 1-year mortality rates, and postoperative complications. Multivariate logistic regression analyses were conducted to identify influencing factors for 1-year mortality in geriatric patients with hip fracture. Results: Baseline data showed statistically significant differences in hemoglobin, albumin and preoperative waiting time between the two groups (all P<0.05). After PSM matching, 69 patients were included in each group, and no significant differences were observed in baseline data between the two groups (all P>0.05). There was no significant differences in 30-day mortality rate (4.3% vs 0, P=0.080), 90-day mortality rate (7.2% vs 1.4%, P=0.095), length of hospital stay [(10.85±4.45)d vs (10.92±3.68)d, P=0.919], total hospitalization cost [(60.9±15.4) thousands yuan vs (59.1±15.4) thousands yuan, P=0.489], postoperative complications [pneumonia (11.6% vs 13.0%, P=0.796), cardio-cerebrovascular complications (11.6% vs 8.7%, P=0.573) and delirium (5.7% vs 2.9%, P=0.245)] between the Friday group and the non-Friday group (all P>0.05). However, the 1-year mortality rate was higher in the Friday group than that in the non-Friday group(18.8% vs 4.3%, P=0.008). Multivariate analysis revealed that surgery on Friday (OR=11.222, 95%CI: 2.198-57.291, P=0.004), low hemoglobin levels at admission (OR=0.920, 95%CI: 0.875-0.967, P=0.001), hemiarthroplasty treatment (OR=5.127, 95%CI: 1.308-20.095, P=0.019) and longer surgery duration (OR=0.958, 95%CI: 0.927-0.989, P=0.009) were influencing factors for 1-year mortality in geriatric patients with hip fracture. Conclusions: In the context of multidisciplinary treatment, Friday surgery does not increase short-term mortality, length of hospital stay, total hospitalization cost or incidence of complications in geriatric patients with hip fracture. However, it remains a influencing factor for 1-year mortality in those patients.

Abstract
Genome-wide association studies (GWAS) and cis-expression quantitative trait locus (cis-eQTL) analyses indicated an association of the rs508419 single nucleotide polymorphism (SNP) with type 2 diabetes (T2D). rs508419 is localized in the muscle-specific internal promoter (P2) of the ANK1 gene, which drives the expression of the sAnk1.5 isoform. Functional studies showed that the rs508419 C/C variant results in increased transcriptional activity of the P2 promoter, leading to higher levels of sAnk1.5 mRNA and protein in skeletal muscle biopsies of individuals carrying the C/C genotype. To investigate whether sAnk1.5 overexpression in skeletal muscle might predispose to T2D development, we generated transgenic mice (TgsAnk1.5/+) in which the sAnk1.5 coding sequence was selectively overexpressed in skeletal muscle tissue. TgsAnk1.5/+ mice expressed up to 50% as much sAnk1.5 protein as wild-type (WT) muscles, mirroring the difference reported between individuals with the C/C or T/T genotype at rs508419. However, fasting glucose levels, glucose tolerance, insulin levels and insulin response in TgsAnk1.5/+ mice did not differ from those of age-matched WT mice monitored over a 12-month period. Even when fed a high-fat diet, TgsAnk1.5/+ mice only presented increased caloric intake, but glucose disposal, insulin tolerance and weight gain were comparable to those of WT mice fed a similar diet. Altogether, these data indicate that sAnk1.5 overexpression in skeletal muscle does not predispose mice to T2D susceptibility.

Abstract
OBJECTIVE To explore the improvements of high-fat intake on lung injury induced by Paragonimus proliferus infection in rats, and to preliminarily explore the mechanisms underlying the role of cytochrome P450 4A1 (CYP 4A1) in the improve ments. METHODS SD rats were randomly assigned into three groups, including the normal control group (n = 10), the infection and normal diet group (n = 12) and the infection and high-fat diet group (n = 12). Rats in the normal control group were fed with normal diet and without any other treatments, and animals in the infection and normal diet group were subcutaneously injected with 8 excysted metacercariae of P. proliferus via the abdominal wall, followed by feeding with normal diet, while rats in the infection and high-fat diet group were subcutaneously injected with 8 excysted metacercariae of P. proliferus via the abdominal wall, followed by feeding with high-fat diet. All rats were sacrificed 28 weeks post-infection, and serum samples and lung specimens were collected. Following hematoxylin-eosin (HE) staining of rat lung specimens, the rat lung injury was observed under an optical microscope, and alveolitis was evaluated using semi-quantitative scoring. Serum interleukin-1β (IL-1β) and tumor necrosis factor alpha (TNF-α) levels were measured using enzyme-linked immunosorbent assay (ELISA), and the cytochrome P450 4A1 (CYP 4A1) expression was quantified in rat lung specimens at transcriptional and translational levels using quantitative real-time PCR (qPCR) and Western blotting assays. RESULTS Alveolar wall thickening, edema and inflammatory cell infiltration were alleviated 28 weeks post-infection with P. proliferus in rats in the infection and high-fat diet group relative to the infection and normal diet group, and no alveolar consolidation was seen in the infection and high-fat diet group. The semi-quantitative score of alveolitis was significantly higher in the infection and normal diet group [(2.200 ± 0.289) points] than in the normal control group [(0.300 ± 0.083) points] and the infection and high-fat diet group [(1.300 ± 0.475) points] (both P values < 0.05), and higher serum IL-1β [(151.586 ± 20.492)] pg/mL and TNF-α levels [(180.207 ± 23.379) pg/mL] were detected in the infection and normal diet group than in the normal control group [IL-1β: (103.226 ± 3.366) pg/mL; TNF-α: (144.807 ± 1.348) pg/mL] and the infection and high-fat diet group [IL-1β: (110.131 ± 12.946) pg/mL; TNF-α: (131.764 ± 27.831) pg/mL] (all P values < 0.05). In addition, lower CYP 4A1 mRNA (3.00 ± 0.81) and protein expression (0.40 ± 0.02) was quantified in lung specimens in the infection and normal diet group than in the normal control group [(5.03 ± 2.05) and (0.84 ± 0.14)] and the infection and high-fat diet group [(11.19 ± 3.51) and (0.68 ± 0.18)] (all P values < 0.05). CONCLUSIONS High-fat intake may alleviate lung injuries caused by P. proliferus infection in rats through up-regulating CYP 4A1 expression in lung tissues at both translational and transcriptional levels.

Abstract
Objective: To investigate the effect of noninvasive positive pressure ventilation(NIPPV) on all-cause mortality in patients with chronic obstructive pulmonary disease-obstructive sleep apnea overlap syndrome(OVS) through long-term follow-up. Methods: A total of 187 OVS patients were divided into the NIPPV group(n=92) and the non-NIPPV group(n=95). Of these, 85 males and 7 females were in the NIPPV group with an average age of (66.5±8.5) years(range 47-80 years); 89 males and 6 females were in the non-NIPPV group with an average age of (67.4±7.8) years(range 44-79 years). Follow-up was performed from enrolment with an average duration of 39(20, 51) months. The all-cause mortality was compared between the two groups. Result: There were no significant differences in their baseline clinical characteristics(all P>0.05), indicating that the data from the two groups were comparable. The Kaplan-Meier curve showed no difference in all-cause mortality between the two groups(log rank P=0.229). However, deaths from cardio-cerebrovascular diseases were higher in the non-NIPPV than in the NIPPV group(15.8% vs. 6.5%,P=0.045). Age, BMI, neck circumference, PaCO2, FEV1, FEV1%, moderate to severe OSA(AHI>15 events/h), mMRC, CAT, number of acute exacerbations of COPD and number of hospitalizations were associated with all-cause death in OVS patients; among which, age(HR 1.067, 95%CI 1.017-1.119, P=0.008), FEV1(HR 0.378, 95%CI 0.176-0.811, P=0.013), and number of COPD exacerbations(HR 1.298, 95%CI 1.102-1.530, P=0.002) were independent risk factors for all-cause mortality in OVS patients. Conclusions: The combination of NIPPV and conventional treatment may reduce cardio-cerebrovascular disease-related mortality in OVS patients. The deceased OVS patients had severe airflow limitation and mild to moderate OSA. Old age, low FEV1 and COPD exacerbations were independent risk factors for all-cause mortality in OVS patients.

Abstract
Objective: To explore the clinical and biochemical discriminants of hyperandrogenism in functional hypothalamic amenorrhea (FHA). Methods: From January to September 2022, a total of 56 patients with FHA group in the Obstetrics and Gynecology Hospital of Fudan University outpatient clinic were included in this retrospective cross-sectional analysis. According to the clinical or biochemical features of hyperandrogenism, FHA patients can be divided into two subgroups, namely hyperandrogenic FHA and non-hyperandrogenic FHA. Explore the differences and its significances between hyperandrogenic FHA and non-hyperandrogenic FHA by comparing anthropometry, reproductive hormones, AMH, ultrasonic manifestation, the scores of eating attitude test, depression questionnaire and anxiety scale respectively and analyzing their correlations. Results: The age of 56 FHA patients was 15-32(23.36±4.90) years, and body mass index(BMI) was (18.91±2.49) kg/m2. The age of hyperandrogenic FHA and non-hyperandrogenic FHA was (21.76±4.40) and (24.05±5.00) (P=0.109) years old respectively, and BMI was (19.14±3.15 )and (18.81±2.18) kg/m2 (P=0.702). Compared to the non-hyperandrogenic FHA, the AMH (6.46 and 3.63 ng/ml, P=0.025) and PRL (278.78 and 149.46 mU/ml, P=0.002) levels were higher in hyperandrogenic FHA group. There was no significant difference between the hyperandrogenic and non-hyperandrogenic FHA group in body composition.GAD-7 (r=0.455, P=0.005) and PHQ-9 (r=0.664, P<0.001) were correlated with EAT-26 scores in non-hyperandrogenic FHA group, but no significant correlation was shown between PHQ-9 (r=0.091, P=0.766)、GAD-7 (r=0.304, P=0.313) and EAT-26 in hyperandrogenic FHA group. Conclusions: Some patients with FHA had clinical manifestations of hyperandrogenism and mildly elevated AMH and PRL, with underlying PCOS endocrine characteristics.

Abstract
PURPOSE The effects of calorie restriction (CR) on gut microbiota and the mechanism of CR ameliorating hyperglycemia in streptozotocin (STZ)-induced T2DM model rats were explored. METHODS High-fat diet and STZ injection were applied to induce T2DM model rats. Rats were divided into the following three groups: the control-diet ad libitum group, the T2DM model group fed with ad libitum diet, and the T2DM group fed with 30% restriction diet. 16S rRNA sequencing was used to determine the bacterial communities. Lipopolysaccharide (LPS)-binding protein (LBP), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were measured. RESULTS Glucose tolerance and insulin sensitivity were improved by CR, as well as the levels of fasting and random plasma glucose. Besides, CR not only modulated the overall structure of gut microbiota but also had selective enrichment in anti-inflammatory bacteria such as Lachnospiraceae_NK4A136_group, Ruminococcaceae_9, Allobaculum, Alistipes, and Oscillibacter, and decreased pro-inflammatory pathogenic bacteria such as Bacteroides, Lachnoclostridium, and Bifidobacterium. Tax4Fun indicated that CR could regulate related functional pathways such as lipopolysaccharide biosynthesis, and the plasma levels of LBP, IL-6, and TNF-α were markedly reduced by CR, suggesting the mechanism of CR ameliorating hyperglycemia may associate with the modulation of disordered gut microbiota and the reduction of metabolic endotoxemia and inflammation. CONCLUSION CR could ameliorate hyperglycemia, the mechanism of which may associate with the alteration of the overall structure of gut microbiota, restoration of disordered microbiota function, and the downregulation of metabolic endotoxemia and inflammation in diabetic rats.

Abstract
Context The expression of TSHR-C on the serum tetraiodothyronine (T4) and TSH receptor antibody (TRAb) levels are rarely studied. Objective The effect of TSHR-c on T4 and TRAb levels and concomitant thyroid histological changes in mice was investigated. Design Animal experimental study. Subjects and methods Female BALB/c mice at 6-8 weeks of age were immunized with the thyroid stimulating hormone receptor antigen C-terminus (TSHR-C), and randomly divided into control group (treated with the corresponding concentrations of normal saline) and four experimental subgroups: TSHR-c1 subgroup (4 µg), TSHR-c2 subgroup (6 µg), TSHR-c3 subgroup (8 µg) and TSHR-c4 subgroup (10 µg). Serum T4 and TRAb levels were determined. Results The serum T4 level decreased significantly in the experimental mice as the concentration increased. All the experimental mice were positive for serum TRAb (experimental groups: 40 positive/40, 100% vs. control group: 3 positive/10, 30%) compared to the control group (P =0.000). HE staining showed that the follicles in the control mice were composed of small to medium-sized round follicles, whereas the follicles in the experimental mice were irregularly enlarged under light microscope. Conclusions TSHR-c immunization resulted in thyroid hormone changes like those observed in hypothyroidism, probably due to the induction of TRAb generation.

Abstract
Objective: To investigate whether rosuvastatin acts on lymphatic system and influences lymphatic system-mediated reverse cholesterol transport to play an anti-atherosclerosis role. Methods: Forty-eight apolipoprotein E-/- mice fed a high fat diet were used to construct the atherosclerosis model. They were randomly divided into 4 groups with 12 rats in each group. They were treated with rosuvastatin, vascular endothelial growth factor-C (VEGF-C) and rosuvastatin+VEGF-C inhibitors as experimental group, and no intervention measures were given in control group. After 8 weeks, aortic plaque area, high density lipoprotein cholesterol (HDL-C) content in lymph fluid, the function of popliteal lymphatic drainage of peripheral Evans blue, and the ability of lymphatic system to transport peripheral cell membrane red fluorescent probes to label high-density lipoprotein (HDL) were detected. Subsequently, the effects of rosuvastatin on proliferation, migration and tubular function of lymphoendothelial cells and the expression of scavenger receptor class B type 1 (SR-B1) on lymphoendothelial cells at different concentrations were detected. Results: Compared with the control group, Rosuvastatin and VEGF-C could reduce the area of aortic atherosclerotic plaque (P<0.05). In addition to rosuvastatin plus VEGF-C inhibitor, the intra-aortic plaque area increased (P<0.05). Compared with the control group, Rosuvastatin could increase the content of HDL-C in lymphatic fluid (P<0.05), enhance the drainage function of lymphatic vessels, and enhance the capacity of HDL in the transport tissue fluid of lymphatic system. Compared with the control group, VEGF-C increased the content of HDL-C in mouse lymph fluid (P<0.01), enhanced the drainage function of popliteal lymphatic canal, and enhanced the ability of lymphatic system to transport HDL. With the addition of VEGF-C inhibitor on the basis of rosuvastatin, the content of HDL-C in lymph fluid was reduced, the drainage of popliteal lymphatic canal was interrupted, and the ability of lymphatic system to transport HDL was reduced. Western blotting showed that rosuvastatin increased the protein expression of SR-B1. Conclusion: Rosuvastatin can promote the proliferation, migration and tube formation of lymphatic endothelial cells. At the same time, SR-B1 expression on lymphatic endothelial cells is promoted, thus enhancing the lymphatic system mediated cholesterol reversal transport and playing the role of anti-atherosclerosis.

Abstract
Objective: To systematically evaluate the efficacy of live Bifidobacterium preparations combined with entecavir in the treatment of hepatitis B virus-related cirrhosis. Methods: PubMed, Web of Science, CNKI, Wanfang, VIP, and other databases were searched electronically until October 2020. Randomized controlled clinical trials in the treatment of hepatitis B virus-related cirrhosis with live Bifidobacterium preparations combined with entecavir were included for statistical analysis. The relative risk (RR) was used as the effect size for the count data. Measurement data were expressed as mean difference (MD) or standardized mean difference (SMD) to represent the effect size. 95% confidence intervals (95% CI) were calculated for each effect size. The I2 statistic and P-values were used to evaluate the heterogeneity of the included literature. The fixed effect model was used for analysis if I (2)≤50%, P > 0.1; otherwise, the random effect model was used for meta-analysis. Results: A total of 865 patients from nine studies were included. Among them, 434 cases were in the live Bifidobacterium preparation combined with the entecavir treatment group and 431 cases in the entecavir group. The results showed that compared with the entecavir group, the live bifidobacterium preparation combined with the entecavir treatment group had significantly reduced the four indicators of liver fibrosis: serum hyaluronic acid (HA) (SMD = -1.87 ng/ml, 95%CI: -2.32 ~ 1.41, P < 0.01), laminin (LN) (SMD = -1.62 ng/ml, 95%CI: -2.04 ~ 1.19, P < 0.01), type III procollagen peptide (PC-III) (SMD = -0.98, 95%CI: -1.26 ~ 0.7, P < 0.01), type IIIcollagen (III-C) (SMD = -1.14 ng/ml, 95%CI: -1.73 ~ 0.55, P < 0.01), portal vein diameter (SMD = -0.91 mm, 95% CI: -1.27 ~ 0.55, P < 0.01) and spleen thickness (MD = -3.26mm, 95%CI: -3.95 ~ 2.58, P < 0.01). However, there was no statistically significant difference in the negative conversion rate of hepatitis B virus DNA (HBV DNA) between the two groups of patients. Conclusion: Compared to the entecavir treatment group, the live Bifidobacterium preparation combined with entecavir showed apparent severity improvement and enhanced clinical efficacy in patients with hepatitis B virus-related cirrhosis.

Abstract
Degradable bone cement has superior osteoconductivity and plasticity and is commonly used to treat defects greater than the critical-size. Magnesium gallate metal-organic frameworks (MOFs) (Mg-MOF), with antibacterial and anti-inflammatory properties, are doped into a composite cement composed of calcium sulfate, calcium citrate, and dicalcium hydrogen phosphate anhydrous (CS/CC/DCPA). The doping of the Mg-MOF slightly influences the microstructure and curing properties of the composite cement, with the mechanical strength of the cement displaying a significant increase from 27 to 32 MPa. Antibacterial tests reveal that the Mg-MOF bone cement has excellent antibacterial characteristics and can effectively inhibit bacterial growth in 4 h (Staphyloccocus aureus survival rate <10%). Herein, lipopolysaccharide (LPS)-induced macrophage models are used to investigate the anti-inflammatory characteristics of composite cement. The Mg-MOF bone cement can regulate the inflammatory factors and polarization of macrophages (M1 and M2). In addition, the composite cement promotes cell proliferation and osteo-differentiation of mBMSCs, and the activity of alkaline phosphatase and calcium nodules are increased. The bone related transcription factor and specific proteins, such as runt-related transcription factor 2 (Runx2), bone morphogenetic protein 2, osteocalcin (OCN), osteopontin (OPN), and collagen type 1 (COL1), were highly expressed by the Mg-MOF bone cements. Therefore, Mg-MOF doped CS/CC/DCPA bone cement is multifunctional for bone repair, which will promote bone formation and avoid the infection of wounds, and it is suitable for use with non-load-bearing bone defects.

Abstract
There are many types in food allergy, and the most common is mediated by IgE. Currently, the diagnosis of food allergy mainly relied on skin prick test and serum specific IgE of allergen extract, which can not identify cross-sensitization. Component-resolved diagnosis (CRD) can identify the major allergen components and cross-components of food allergens, which plays an important role in dietary guidance, prognosis monitoring and diagnosis of special types of IgE-mediated food allergy. This article enumerates clinical characteristics of the IgE-mediated common food allergies, such as milk, egg and seafood allergy, and special type of food allergy, such as cat pork syndrome, oral allergy syndrome, α-gal syndrome and food-dependent exercise-induced anaphylaxis, summarizes the advances of CRD in these types of IgE-mediated food allergy, in order to provide an evidence for the diagnosis, treatment and prevention of IgE-mediated food allergy.

Abstract
AIM To evaluate the predictive performance of the radiomics model in predicting axillary lymph node (ALN) metastasis through the associations between radiomics features and genomic features in patients with breast cancer. MATERIALS AND METHODS Patients with breast cancer were enrolled retrospectively from a public database (111 patients as training group) and one hospital (15 patients as external validation group). The genomics features from transcriptome data and radiomics features from dynamic contrast-enhanced magnetic resonance imaging (MRI) were collected. Firstly, overlapping genes were identified using the Kyoto Encyclopedia of Genes and Genomes and differentially expressed gene analysis, while radiomics features were reduced using a data-driven method. Then, the associations between overlapping genes and retained radiomics features were assessed to obtain key pairs of radiomics-genomics features. Furthermore, the least absolute shrinkage and selection operator (LASSO) algorithm was used to detect the key-pairs features. Finally, radiomics and genomics models were constructed to predict ALN metastasis. RESULTS After using the hybrid data- and gene-driven selection method, key pairs of features were detected, which consisted of six radiomic features associated with four genomic features. The radiomics model exhibited comparable performance to the genomics model in predicting ALN metastasis (radiomic model: area under the curve [AUC] = 0.71, sensitivity = 77%, specificity = 56%; genomic model: AUC = 0.72, sensitivity = 85%, specificity = 74%). The four genomic features were enriched in six pathways and related to metabolism and human diseases. CONCLUSION The radiomics model established using the gene-driven hybrid selection method could predict ALN metastasis in breast cancer, which showed comparable performance to the genomics model.

Abstract
The objective of this study was to examine to what extent the anatomic characteristics of the upper airway can influence the effect of nocturnal wearing of dentures on the sleep of edentulous elders with untreated sleep apnea. This study used the data from a randomized crossover clinical trial and an exploratory approach to address its objectives. Cone beam computed tomography scans of 65 edentulous individuals (female, n = 37; male, n = 28; mean ± SD age, 74.54 ± 6.42 y) with untreated obstructive sleep apnea (OSA) were used to identify anatomic variables. Polysomnography data were collected by means of one portable overnight recording. The respiratory variable values, including apnea-hypopnea index (AHI), with and without denture worn during sleep were used to calculate the change. Statistical analyses included multiple linear regressions, cluster analysis, and binary logistic regressions. A receiver operator characteristic curve was used to illustrate the accuracy of the statistical model. The regression model explained 15.8% (R2) of AHI change. An increase in the lateral dimension of the minimum cross-sectional area was associated with a decrease in AHI, oxygen desaturation index, and respiratory arousal index changes (P ≤ 0.041). Furthermore, an increase in the length of the hypopharynx was associated with an increase in AHI and oxygen desaturation index changes (P ≤ 0.027). An increase in the lateral dimension of the minimum cross-sectional area of the upper airway was associated with a decreased likelihood of being in the group having a worsened AHI (odds ratio = 0.85; 95% CI, 0.76 to 0.95; P = 0.006). An increase in the length of the oropharynx was associated with an increased likelihood of having increased AHI (odds ratio = 1.10; 95% CI, 1.01 to 1.20; P = 0.026). The nocturnal aggravation of respiratory variables in edentulous individuals with OSA who wear dentures at night can be linked to certain anatomic characteristics of the upper airway. Replication of these findings may open novel avenues for personalized advice regarding nocturnal wearing of dentures in edentulous individuals with OSA (ClinicalTrials.gov: NCT01868295).

Abstract
In this study, we evaluated a novel functional monomer (4-formylphenyl acrylate [FA]) that can specifically and covalently bind to the dentin collagen matrix as a potential alternative hydrophobic diluent-like monomer for improving the durability of dentin bonding. Experimental adhesives with different FA contents (0%, 10%, 20%, and 30%) were evaluated as partial substituents for the hydrophilic monomer 2-hydroxyethyl methacrylate, with the commercial adhesive One-Step (Bisco, Inc.) employed as the positive control. Their degree of conversion, viscosity, hydrophobicity, mechanical properties, and water absorption/solubility were measured as the comprehensive characterization. In situ zymographic assays were performed to determine the extent to which FA inhibits the endogenous hydrolytic activity of dentin. Finally, the bonding performances of the novel adhesives were evaluated with microtensile strength tests and scanning electron microscopy. The results showed that the incorporation of FA significantly improved the mobility of experimental adhesives attributable to the dilution property of FA. In contrast to the possible compromised rate of polymerization by hydroxyethyl methacrylate, FA exhibited typical characteristics of favorable copolymerization with polymerizable monomers in adhesives and improved the degree of conversion of experimental adhesives. The rigidity and hydrophobic properties of the phenyl framework of the FA molecule conferred superior mechanical properties and hydrolysis resistance to the novel experimental adhesives. An inhibitory effect on gelatinolytic activities within the hybrid layer was also observed in the in situ zymographic assays, even at a low FA concentration (10%). In conjunction with the significantly improved infiltration found via scanning electron microscopy, the experimental adhesives containing FA possessed significantly better-maintained microtensile strength, even after aging. Thus, the incorporation of this novel monomer endowed the experimental adhesives with multiple enhanced functionalities. These remarkable advantages highlight the suitability of the monomer for further applications in clinical practice.

Abstract
Objectives: To evaluate microvascular perfusion and left ventricular function in patients with acute ST-segment elevation myocardial infarction after revascularization using myocardial contrast echocardiography (MCE), and to explore clinical influencing factors of abnormal microvascular perfusion in these patients. Methods: This is a cross-sectional study. The analysis was performed among patients admitted to Peking University People's Hospital for acute ST-segment elevation myocardial infarction (STEMI) from June 2018 to July 2021. All patients underwent percutaneous coronary intervention (PCI) and completed MCE within 48 hours after PCI. Patients were divided into normal myocardial perfusion group and abnormal perfusion group according to the myocardial perfusion score. The echocardiographic indexes within 48 hours after PCI, including peak mitral valve flow velocity (E), mean value of early diastolic velocity of left ventricular septum and lateral mitral annulus (Em), left ventricular global longitudinal strain (GLS) and so on, were analyzed and compared between the two groups. Multivariate logistic regression analysis was used to evaluate the influencing factors of myocardial perfusion abnormalities. Results: A total of 123 STEMI patients, aged 59±13 years with 93 (75.6%) males, were enrolled. There were 50 cases in the normal myocardial perfusion group, and 73 cases in the abnormal myocardial perfusion group. The incidence of abnormal myocardial perfusion was 59.3% (73/123). The left ventricular volume index ((62.3±18.4)ml/m2 vs. (55.1±15.2)ml/m2, P=0.018), wall motion score index (WMSI) (1.59 (1.44, 2.00) vs. 1.24(1.00, 1.47), P<0.001) and mitral E/Em (17.8(12.0, 24.3) vs. 12.2(9.2, 15.7), P<0.001) were significantly higher whereas left ventricular global longitudinal strain (GLS) ((-10.8±3.4)% vs. (-13.8±3.5)%, P<0.001) was significantly lower in the abnormal myocardial perfusion group than those in the normal myocardial perfusion group. Multivariate logistic regression analysis showed that left anterior descending (LAD) as culprit vessel (OR=3.733, 95%CI 1.282-10.873, P=0.016), intraoperative no/low-reflow (OR=6.125, 95%CI 1.299-28.872, P=0.022), and peak troponin I (TnI) (OR=1.018, 95%CI 1.008-1.029, P=0.001) were independent risk factors of abnormal myocardial perfusion. As for ultrasonic indexes, deceleration time of mitral E wave (OR=0.979, 95%CI 0.965-0.993, P=0.003), mitral E/Em (OR=1.100, 95%CI 1.014-1.194, P=0.022) and WMSI (OR=7.470, 95%CI 2.630-21.222, P<0.001) were independently related to abnormal myocardial perfusion. Conclusions: The incidence of abnormal myocardial perfusion after PCI is high in patients with acute STEMI. Abnormal myocardial perfusion is related to worse left ventricular systolic and diastolic function. LAD as culprit vessel, intraoperative no/low-reflow and peak TnI are independent risk factors of abnormal myocardial perfusion.

Abstract
Giant cell tumors (GCTs) of the bone are locally aggressive primary bone tumors with a benign character. Spinal involvement is rare which accounts for approximately 5% of all primary bone tumors and it is quite rare in the lumbar spine. An 11-year-old boy patient presented with pain of low back and bilateral low extremities. Lumbar CT and MRI revealed a lytic lesion of the L4 vertebra corpus. The patient earned remarkable and timely recovery with 2 surgical interventions and the use of denosumab. Surgical resection for GCTs is still preferable as the initial treatment, denosumab should be utilized after tumor resection whether based on the purpose of prevention or treatment of tumor recurrence.
