Abstract
BACKGROUND The present study investigated the structure, functional and physicochemical properties of lotus seed protein (LSP) under different pH environments. The structures of LSP were characterized by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, Fourier transform infrared spectroscopy (FTIR), zeta potential, particle size distributions, free sulfhydryl and rheological properties. The functional and physicochemical properties of LSP were characterized by color, foaming property, emulsification property, solubility, oil holding capacity, water holding capacity, differential scanning calorimetry analysis and surface hydrophobicity. RESULTS LSP was mainly composed of eight subunits (18, 25, 31, 47, 51, 56, 65 and 151 kDa), in which the richest band was 25 kDa. FTIR results showed that LSP had high total contents of α-helix and β-sheet (44.81-46.85%) in acidic environments. Meanwhile, there was more β-structure and random structure in neutral and alkaline environments (pH 7.0 and 9.0). At pH 5.0, LSP had large particle size (1576.98 nm), high emulsion stability index (91.43 min), foaming stability (75.69%) and water holding capacity (2.21 g g-1), but low solubility (35.98%), free sulfhydryl content (1.95 μmol g-1) and surface hydrophobicity (780). DSC analysis showed the denaturation temperatures (82.23 °C) of LSP at pH 5.0 was higher than those (80.10, 80.52 and 71.82 °C) at pH 3.0, 7.0 and 9.0. The analysis of rheological properties showed that LSP gel had high stability and great strength in an alkaline environment. CONCLUSION The findings of the present study are anticipated to serve as a valuable reference for the implementation of LSP in the food industry. © 2024 Society of Chemical Industry.

Abstract
BACKGROUND Zanthoxylum seed, as a low-cost and easily accessible plant protein resource, has good potential in the food industry. But protein and its hydrolysates from Zanthoxylum seed are underutilized due to the dearth of studies on them. This study aimed to investigate the structure and physicochemical and biological activities of Zanthoxylum seed protein (ZSP) hydrolysates prepared using Protamex®, Alcalase®, Neutrase®, trypsin, or pepsin. RESULTS Hydrolysis using each of the five enzymes diminished average particle size and molecular weight of ZSP but increased random coil content. ZSP hydrolysate prepared using pepsin had the highest degree of hydrolysis (24.07%) and the smallest molecular weight (<13 kDa) and average particle size (129.80 nm) with the highest solubility (98.9%). In contrast, ZSP hydrolysate prepared using Alcalase had the highest surface hydrophobicity and foaming capacity (88.89%), as well as the lowest foam stability (45.00%). Moreover, ZSP hydrolysate prepared using Alcalase exhibited the best hydroxyl-radical scavenging (half maximal inhibitory concentration (IC50 ) 1.94 mg mL-1 ) and ferrous-ion chelating (IC50 0.61 mg mL-1 ) activities. Additionally, ZSP hydrolysate prepared using pepsin displayed the highest angiotensin-converting enzyme inhibition activity (IC50 0.54 mg mL-1 ). CONCLUSION These data showed that enzyme hydrolysis improved the physicochemical properties of ZSP, and enzymatic hydrolysates of ZSP exhibited significant biological activity. These results provided validation for application of ZSP enzymatic hydrolysates as antioxidants and antihypertensive agents in the food or medicinal industries. © 2023 Society of Chemical Industry.

Abstract
BACKGROUND The limited physicochemical properties (such as low foaming and emulsifying capacity) of mung bean protein hydrolysate restrict its application in the food industry. Ultrasound treatment could change the structures of protein hydrolysate to accordingly affect its physicochemical properties. The aim of this study was to investigate the effects of ultrasound treatment on the structural and physicochemical properties of mung bean protein hydrolysate of protamex (MBHP). The structural characteristics of MBHP were evaluated using tricine sodium dodecylsulfate-polyacrylamide gel electrophoresis, laser scattering, fluorescence spectrometry, etc. Solubility, fat absorption capacity and foaming, emulsifying and thermal properties were determined to characterize the physicochemical properties of MBHP. RESULTS MBHP and ultrasonicated-MBHPs (UT-MBHPs) all contained five main bands of 25.8, 12.1, 5.6, 4.8 and 3.9 kDa, illustrating that ultrasound did not change the subunits of MBHP. Ultrasound treatment increased the contents of α-helix, β-sheet and random coil and enhanced the intrinsic fluorescence intensity of MBHP, but decreased the content of β-turn, which demonstrated that ultrasound modified the secondary and tertiary structures of MBHP. UT-MBHPs exhibited higher solubility, foaming capacity and emulsifying properties than MBHP, among which MBHP-330 W had the highest solubility (97.32%), foaming capacity (200%), emulsification activity index (306.96 m2 g-1 ) and emulsion stability index (94.80%) at pH 9.0. CONCLUSION Ultrasound treatment enhanced the physicochemical properties of MBHP, which could broaden its application as a vital ingredient in the food industry. © 2023 Society of Chemical Industry.

Abstract
The purpose of this study was to investigate structural, functional and antioxidant properties of Lentinus edodes protein hydrolysates (LEPHs) by alcalase, protamex, trypsin, papain and neutrase. Structural and functional properties were determined using gel electrophoresis, Fourier transform infrared spectroscopy, laser scattering, fluorescence spectroscopy, emulsifying properties etc. Antioxidant activities were detected by Fe2+ chelating, hydroxyl and DPPH radical scavenging assays. Enzymatic hydrolysis destroyed secondary and tertiary structures of Lentinus edodes protein, decreased its molecular weight and particle size, particularly hydrolysate prepared by alcalase with the highest hydrolytic degree (32.86 ± 0.98 %), the smallest particle (130.77 ± 1.85 nm) and molecular weight (5.86 kDa). Moreover, alcalase hydrolysate exhibited the highest emulsifying stability, the strongest hydroxyl radical scavenging activity and Fe2+ chelating ability among LEPHs. Whilst trypsin hydrolysate displayed the highest DPPH radical scavenging, foaming and fat absorption capacity. These results provided basis for LEPH as ingredients to be used for food industry.

Abstract
OBJECTIVES Given the global prevalence of dental caries, impacting 2.5 billion individuals, the development of sophisticated prevention filling materials is crucial. Streptococcus mutans, the principal caries-causing strain, produces acids that demineralize teeth and initiate dental caries. To address this issue, we aimed to develop a synergistic resin-based composite for enhancing caries control. METHODS The synergistic resin composite incorporates fluorinated kaolinite and silanized Al2O3 nanoparticle fillers into an epigallocatechin gallate (EGCG) immobilized urethane-modified epoxy acrylate (U-EA) resin matrix, referred to the as-prepared resin composite. The EGCG-modified TPGDA/U-EA network was synthesized by preparing methacrylate-functionalized isocyanate (HI), reacting it with EGCG to form HI-EGCG, and then incorporating HI-EGCG into the TPGDA/U-EA matrix. The lamellar space within the kaolinite layer was expanded through the intercalation of acrylamide into kaolinite, enhancing its capability to adsorb and release fluoride ions (F-). The layered structure of acrylamide/ kaolinite in the U-EA resin composite acts as a F- reservoir. RESULTS The physico-mechanical properties of the as-prepared resin composites are comparable to those of commercial products, exhibiting lower polymerization shrinkage, substantial F- release and recharge and favorable diametral tensile strength. The immobilized EGCG in the composite exhibits potent antimicrobial properties, effectively reducing the biofilm biomass. Furthermore, the synergistic effect of EGCG and fluorinated kaolinite efficiently counteracts acid-induced hydroxyapatite dissolution, thereby suppressing demineralization and promoting enamel remineralization. SIGNIFICANCE Our innovative EGCG and fluoride synergistic composite provides enhanced antimicrobial properties, durable anti-demineralization, and tooth remineralization effects, positioning it as a promising solution for effective caries control and long-term dental maintenance.

Abstract
Analyses of National Health and Nutrition Examination Survey (NHANES) data suggested a significant decrease in sealant prevalence among children between 2011 to 2014 and 2015 to 2018. We explore whether this decrease could be associated with possible changes in 1) clinical sealant delivery, 2) dental materials (i.e., increased use of glass ionomer [GI] sealants resulting in an inability to detect sealant fragments that still provide preventive benefits or increased use of composite restorations leading to misclassifying sealants as restorations), and 3) examination sensitivity and specificity. We used NHANES data to estimate the prevalences of sealants, untreated caries, and restorations in ≥1 first permanent molar among children aged 7 to 10 y and used Medical Expenditure Panel Survey data to estimate the annual clinical delivery of sealants and fluoride treatments. We examined changes in outcomes between 2 periods (P < 0.05) controlling for selected sociodemographic characteristics. NHANES sealant examination quality was based on the reference examiner's replicate examinations. The adjusted prevalence of sealants decreased relatively by 27.5% (46.6% vs. 33.8%). Overall, untreated caries decreased. Untreated caries and restoration decreased among children without sealants. Annual clinical sealant delivery did not change, whereas fluoride treatment delivery increased. The decrease in sealant prevalence held when assessed for various age ranges and NHANES cycle combinations. While sealant examination specificity remained similar between the periods, sensitivity (weighted by the proportion of exams by each examiner) decreased relatively by 17.4% (0.92 vs. 0.76). These findings suggest that decreased sealant prevalence was not supported by decreased clinical sealant delivery nor increased use of composite restorations. Decreased examination sensitivity, which could be due to an increased use of GI sealants, could contribute to the decrease in sealant prevalence. The decrease in caries among children without sealants could suggest the increased use of GI sealants. However, we could not rule out that the decrease in caries could be attributable to increased fluoride treatment delivery.

Abstract
Background/purpose External cervical resorption (ECR) is an aggressive form of root resorption, which etiology is unclear and its prognosis remains unpredictable. The purpose of this study was to investigate the prognosis and potential prognostic factors of ECR-affected teeth after surgical intervention for external repair with/without root canal treatment. Materials and methods Treated ECR cases from 2009 to 2019 were collected retrospectively. The survival of the teeth and the status of root resorption were assessed during the follow-up period. Potential prognostic factors were analyzed with log-rank test and Kaplan-Meier statistics. Results A total of 42 treated ECR-affected teeth were enrolled. The two-year survival rate was 71.20% [54.16%, 93.59%]. Persistent root resorption was the main complication after treatment. Patients with multiple ECR-affected teeth had greater recurrent potential than patients with solitary ECR-affected teeth. Prolonged calcium hydroxide dressing may contribute to a more favorable clinical outcome. Gender, age, tooth position and the need for root canal treatment did not show statistically significant effect on the prognosis. Conclusion The current surgical method was able to arrest ECR in most cases. However, the case type (the number of ECR-affected teeth per patient) could highly affect the prognosis of the teeth. Clinicians should consider long-term calcium hydroxide dressing in case of pulp involvement to achieve better results.

Abstract
BACKGROUND In previous analyses, myocardial injury after noncardiac surgery, major bleeding, and sepsis were independently associated with most deaths in the 30 days after noncardiac surgery, but most of these deaths occurred during the index hospitalization for surgery. The authors set out to describe outcomes after discharge from hospital up to 1 yr after inpatient noncardiac surgery and associations between predischarge complications and postdischarge death up to 1 yr after surgery. METHODS This study was an analysis of patients discharged after inpatient noncardiac surgery in a large international prospective cohort study across 28 centers from 2007 to 2013 of patients aged 45 yr or older followed to 1 yr after surgery. The study estimated (1) the cumulative postdischarge incidence of death and other outcomes up to a year after surgery and (2) the adjusted time-varying associations between postdischarge death and predischarge complications including myocardial injury after noncardiac surgery, major bleeding, sepsis, infection without sepsis, stroke, congestive heart failure, clinically important atrial fibrillation or flutter, amputation, venous thromboembolism, and acute kidney injury managed with dialysis. RESULTS Among 38,898 patients discharged after surgery, the cumulative 1-yr incidence was 5.8% (95% CI, 5.5 to 6.0%) for all-cause death and 24.7% (95% CI, 24.2 to 25.1%) for all-cause hospital readmission. Predischarge complications were associated with 33.7% (95% CI, 27.2 to 40.2%) of deaths up to 30 days after discharge and 15.0% (95% CI, 12.0 to 17.9%) up to 1 yr. Most of the association with death was due to myocardial injury after noncardiac surgery (15.6% [95% CI, 9.3 to 21.9%] of deaths within 30 days, 6.4% [95% CI, 4.1 to 8.7%] within 1 yr), major bleeding (15.0% [95% CI, 8.3 to 21.7%] within 30 days, 4.7% [95% CI, 2.2 to 7.2%] within 1 yr), and sepsis (5.4% [95% CI, 2.2 to 8.6%] within 30 days, 2.1% [95% CI, 1.0 to 3.1%] within 1 yr). CONCLUSIONS One in 18 patients 45 yr old or older discharged after inpatient noncardiac surgery died within 1 yr, and one quarter were readmitted to the hospital. The risk of death associated with predischarge perioperative complications persists for weeks to months after discharge. EDITOR’S PERSPECTIVE

Abstract
Objective: To investigate the reproductive toxicity of cadmium sulfide nanoparticles (Nano-CdS) with different particle sizes on male mice. Methods: In January 2019, 30 SPF grade male mice were randomly divided into a control group, an experimental group[CdS Ⅰ group (particle size approximately 5 nm), and a CdS Ⅱ group (particle size approximately 50 nm) ], with 10 mice in each group. The experimental group was orally gavaged with 100 mg/kg, once a day, while the control group was gavaged with an equal volume of physiological saline for 45 consecutive days. After 45 days, levels of cadmium accumulation in testis were determined directly by AAS, deformity and testicular histopathological changes were also observed. Serum testosterone levels were measured by enzyme-linked immunosorbentassay (ELISA), expression levels of P450scc, 17β-HSD and P450c17 mRNA were determined by real-time PCR. P450c17 protein was determinated by Western Blot. Results: The histopathological results showed that the testes of the experimental group mice showed varying degrees of damage; Ultrastructural observation showed that the ultrastructure of mouse testicular cells in each experimental group showed varying degrees of mitochondrial expansion and disappearance of cristae, as well as irregular nuclear membranes. The degree of damage in CdS Ⅰ group was milder than that in CdS Ⅱ group. Compared with the control group, the cadmium content in the testes of the CdS Ⅰ and CdS Ⅱ groups significantly increased (P=0.001, 0.001), and the CdS Ⅱ group was higher than the CdS Ⅰ group (P=0.001). Compared with the control group, the levels of testosterone in the CdS Ⅰ and CdS Ⅱ groups decreased with statistical significance (P=0.001, 0.001). Real time fluorescence quantitative PCR results showed that compared with the control group, the experimental group's P450scc, 17β-HSD. The expression levels of 17β-HSD and P450c17 mRNA were significantly reduced, with statistically significant differences (P=0.001, 0.001, 0.001), and CdS Ⅱ group 17β-HSD. The expression levels of 17β-HSD and P450c17 mRNA were significantly lower than those of CdS Ⅰ group (P=0.001, 0.036). The Western Blot assay results showed that the expression levels of P450c17 protein in the testes of CdS Ⅰ and CdS Ⅱ groups of mice were significantly reduced, with statistical significance (P=0.001, 0.001) ; And the CdS Ⅱ group was significantly lower than the CdS Ⅰ group (P=0.001). According to Spearman correlation analysis, testosterone levels are correlated with P450scc, P450c17, 17β-HSD mRNA. There is a highly positive correlation between 17β-HSD mRNA levels, with statistically significant differences (r(s)=0.88, 0.80, 0.70, P=0.001, 0.001, 0.004) . Conclusion: Nano cadmium sulfide may induce reproductive toxicity by reducing the expression levels of key enzyme genes and enzyme protein activity in testosterone and its synthesis in mice, and the CdS Ⅱ group has a stronger toxic effect.

Abstract
Objective: To analyze the morbidity characteristics of new occupational diseases in Taian City from 2006 to 2021 and provide scientific evidence for local prevention and treatment of occupational diseases. Methods: In March 2022, the data of newly diagnosed occupational diseases in Taian City from 2006 to 2021 were obtained from Information Monitoring System for Occupational Diseases and Health Hazards. A descriptive analysis was performed for the distribution of onset age, working years, types of occupational diseases, region, industries, enterprise scale, enterprise economic type and the epidemic trend of occupational diseases. Results: 1362 cases of occupational diseases in 29 species of 9 categories were reported in Taian City from 2006 to 2021, including 1311 males and 51 females. The M (P(25), P(75)) of onset age and working age were 53 (47, 64) and 24.08 (16.56, 29.25) respectively. The top three categories of occupational diseases were occupational pneumoconiosis and other respiratory diseases (1128 cases, 82.82%), occupational otolaryngology and oral diseases (107 cases, 7.86%), and occupational chemical poisoning (70 cases, 5.14%) in sequence. Coal worker's pneumoconiosis, noise deafness, silicosis, poisoning of manganese and its compounds and cataract were the top five species of occupational diseases, which accounted for 69.60% (948/1362), 7.64% (104/1362), 5.58% (76/1362), 3.38% (46/1362) and 2.94% (40/1362) of the total cases of occupational diseases.There were significant differences among the composition of occupational diseases categories reported annually (P<0.001), but the number of occupational pneumoconiosis and other respiratory diseases was the highest on each year. The number of occupational diseases showed a decreasing trend with the year, and the optimal fitting curve was an growth curve. The number of newly diagnosed occupational diseases was predicted to be 172 cases from 2022 to 2026. Occupational pneumoconiosis and other respiratory diseases was the main disease in 6 counties. The occupational diseases cases were mainly distributed in Feicheng County and Xintai County, with 520 cases and 504 cases respectively, accounting for 75.18% of occupational diseases cases. The coal mining and washing industry had the largest number of occupational diseases cases, accounting for 73.05% of all occupational diseases cases. 91.85% of occupational diseases cases came from large and medium-sized enterprises. The economic type of enterprises with the most occupational diseases was state-owned enterprises, accounting for 74.52% of occupational diseases cases. Conclusion: The predominant occupational diseases in Taian City are occupational pneumoconiosis and other respiratory diseases, occupational otolaryngology and oral diseases, occupational chemical poisoning. And the prevention and control of occupational diseases should be strengthened in key industries such as coal mining and washing industry, key enterprises such as state-owned large and medium-sized enterprises.

Abstract
We experimentally realize a meterscale strong coupling effect between magnons and photons at room temperature, with a coherent coupling of ∼20 m and a dissipative coupling of ∼7.6 m. To this end, we integrate a saturable gain into a microwave cavity and then couple this active cavity to a magnon mode via a long coaxial cable. The gain compensates for the cavity dissipation, but preserves the cavity radiation that mediates the indirect photon-magnon coupling. It thus enables the long-range strong photon-magnon coupling. With full access to traveling waves, we demonstrate a remote control of photon-magnon coupling by modulating the phase and amplitude of traveling waves, rather than reconfiguring subsystems themselves. Our method for realizing long-range strong coupling in cavity magnonics provides a general idea for other physical systems. Our experimental achievements may promote the construction of information networks based on cavity magnonics.

Abstract
OBJECTIVES This study aimed to evaluate the impact of chlorhexidine (CHX) gel on inflammation-induced periodontal tissue destruction, osteoclastogenesis, subgingival microbiota, and on the modulation of the RANKL/OPG as well as inflammatory mediators during bone remodeling in vivo. MATERIALS AND METHODS Ligation- and LPS injection-induced experimental periodontitis were created to investigate the effect of topical application of CHX gel in vivo. Alveolar bone loss, osteoclast number and gingival inflammation was evaluated by micro-CT, histological, immunohistochemistry and biochemical analysis. The composition of the subgingival microbiota was characterized by 16S rRNA gene sequencing. RESULTS Data shows significant decreases in the alveolar bone destruction in rats from ligation-plus-CHX gel group compared to ligation group. In addition, significant decreases in the number of osteoclasts on bone surface and the protein level of receptor activator of nuclear factor κB ligand (RANKL) in gingival tissue were observed in rats from ligation-plus-CHX gel group. Moreover, data shows significantly decreased inflammatory cell infiltration and decreased expression of cyclooxygenase (COX-2) and inducible NO synthase (iNOS) in gingival tissue from ligation-plus-CHX gel group versus ligation group. Assessment of the subgingival microbiota revealed changes in rats with CHX gel application treatment. CONCLUSION HX gel presents protective effect on gingival tissue inflammation, osteoclastogenesis, RANKL/OPG expression, inflammatory mediators, and alveolar bone loss in vivo, which may have a translational impact on the adjunctive use in the management of inflammation-induced alveolar bone loss.

Abstract
The two most commonly used airway management techniques during general anaesthesia are supraglottic airway devices and tracheal tubes. In older patients undergoing elective non-cardiothoracic surgery under general anaesthesia with positive pressure ventilation, we hypothesised that a composite measure of in-hospital postoperative pulmonary complications would be less frequent when a supraglottic airway device was used compared with a tracheal tube. We studied patients aged ≥ 70 years in 17 clinical centres. Patients were allocated randomly to airway management with a supraglottic airway device or a tracheal tube. Between August 2016 and April 2020, 2900 patients were studied, of whom 2751 were included in the primary analysis (1387 with supraglottic airway device and 1364 with a tracheal tube). Pre-operatively, 2431 (88.4%) patients were estimated to have a postoperative pulmonary complication risk index of 1-2. Postoperative pulmonary complications, mostly coughing, occurred in 270 of 1387 patients (19.5%) allocated to a supraglottic airway device and 342 of 1364 patients (25.1%) assigned to a tracheal tube (absolute difference -5.6% (95%CI -8.7 to -2.5), risk ratio 0.78 (95%CI 0.67-0.89); p < 0.001). Among otherwise healthy older patients undergoing elective surgery under general anaesthesia with intra-operative positive pressure ventilation of their lungs, there were fewer postoperative pulmonary complications when the airway was managed with a supraglottic airway device compared with a tracheal tube.

Abstract
Tranexamic acid is an antifibrinolytic drug that is widely used during surgery, but there are concerns about its thromboembolic effects. We aimed to investigate the effect of prophylactic intravenous tranexamic acid on thromboembolic outcomes in patients undergoing non-cardiac surgery. The MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials were searched. Randomised controlled trials comparing intravenous tranexamic acid with placebo or no treatment in patients undergoing non-cardiac surgery were included. The primary outcome was a composite of peri-operative cardiovascular thromboembolic events, defined as any deep vein thrombosis, pulmonary embolism, myocardial ischaemia/infarction or cerebral ischaemia/infarction. A total of 191 randomised controlled trials (40,621 patients) were included in the review. The primary outcome occurred in 4.5% of patients receiving intravenous tranexamic acid compared with 4.9% of patients in the control group. Our analysis showed that there was no difference between groups for composite cardiovascular thromboembolic events (risk ratio 1.02, 95%CI 0.94-1.11, p = 0.65, I2 0%, n = 37,512). This finding remained robust when sensitivity analysis was performed with continuity correction and in studies with a low risk of bias. However, in trial sequential analysis, our meta-analysis only achieved 64.6% of the required information size. There was no association between intravenous tranexamic acid and seizure rate or mortality rate within 30 days. Intravenous tranexamic acid was associated with a reduced blood transfusion rate compared with control (9.9% vs. 19.4%, risk ratio 0.46, 95%CI 0.41-0.51, p < 0.0001). It was encouraging to see the evidence that the administration of intravenous tranexamic in patients undergoing non-cardiac surgery was not associated with an increased risk of thromboembolic outcomes. However, our trial sequential analysis demonstrated that currently available evidence is not yet sufficient to reach a firm conclusion.

Abstract
The U6 promoter is an important element driving sgRNA transcription in the CRISPR/Cas9 system. Seven PqU6 promo-ter sequences were cloned from the gDNA of Panax quinquefolium, and the transcriptional activation ability of the seven promoters was studied. In this study, seven PqU6 promoter sequences with a length of about 1 300 bp were cloned from the adventitious roots of P. quinquefolium cultivated for 5 weeks. Bioinformatics tools were used to analyze the sequence characteristics of PqU6 promoters, and the fusion expression vectors of GUS gene driven by PqU6-P were constructed. Tobacco leaves were transformed by Agrobacterium tumefaciens-mediated method for activity detection. The seven PqU6 promoters were truncated from the 5'-end to reach 283, 287, 279, 289, 295, 289, and 283 bp, respectively. The vectors for detection of promoter activity were constructed with GUS as a reported gene and used to transform P. quinquefolium callus and tobacco leaves. The results showed that seven PqU6 promoter sequences(PqU6-1P to PqU6-7P) were cloned from the gDNA of P. quinquefolium, with the length ranged from 1 246 bp to 1 308 bp. Sequence comparison results showed that the seven PqU6 promoter sequences and the AtU6-P promoter all had USE and TATA boxes, which are essential elements affecting the transcriptional activity of the U6 promoter. The results of GUS staining and enzyme activity test showed that all the seven PqU6 promoters had transcriptional activity. The PqU6-7P with a length of 1 269 bp had the highest transcriptional activity, 1.31 times that of the positive control P-35S. When the seven PqU6 promoters were truncated from the 5'-end(PqU6-1PA to PqU6-7PA), their transcriptional activities were different in tobacco leaves and P. quinquefolium callus. The transcriptional activity of PqU6-7PA promoter(283 bp) was 1.59 times that of AtU6-P promoter(292 bp) when the recipient material was P. quinquefolium callus. The findings provide more ideal endogenous U6 promoters for CRISPR/Cas9 technology in ginseng and other medicinal plants.

Abstract
Objective: To investigate the clinical and biological characteristics of familial platelet disorder (FPD) with germline Runt-related transcription factor (RUNX) 1 mutations. Methods: Patients diagnosed with myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) with RUNX1 mutations from February 2016 to December 2021 in Wuhan No.1 Hospital underwent pedigree analysis and were screened for gene mutations (somatic and germline). Patients diagnosed with FPD with germline RUNX1 mutations were enrolled and evaluated in terms of clinical characteristics and biological evolution. Bioinformatics analysis was used to assess the pathogenicity of mutations and to analyze the effect of mutated genes on the function of the corresponding protein. Results: Germline RUNX1 mutations were detected in three out of 34 patients suffering from MDS/AML who had RUNX1 mutations. A pedigree of FPD with RUNX1 (RUNX1-FPD) c.562A>C and RUNX1 c.1415T>C mutations was diagnosed, and the mutations were of patrilineal origin. Bioinformatics analysis indicated that the locus at positions 188 and 472 in the AML-1G type of RUNX1 was highly conserved across different species, and that variations might influence functions of the proteins. The mutations were evaluated to be highly pathogenic. Of the nine cases with germline RUNX1 mutations: two patients died due AML progression; one case with AML survived without leukemia after transplantation of hemopoietic stem cells; four patients showed mild-to-moderate thrombocytopenia; two cases had no thrombocytopenia. During the disease course of the proband and her son, mutations in RUNX1, NRAS and/or CEBPA and KIT appeared in succession, and expression of cluster of differentiation-7 on tumor cells was enhanced gradually. None of the gene mutations correlated with the tumor were detected in the four cases not suffering from MDS/AML, and they survived until the end of follow-up. Conclusions: RUNX1-FPD was rare. The mutations c.562A>C and c.1415T>C of RUNX1 could be the disease-causing genes for the family with RUNX1-FPD, and these mutations could promote malignant transformation. Biological monitoring should be carried out regularly to aid early intervention for family members with RUNX1-FPD.

Abstract
We observe a power-dependent anticrossing of Walker spin-wave modes under microwave pumping when a ferrimagnet is placed in a microwave waveguide that does not support any discrete photon mode. We interpret this unexpected anticrossing as the generation of a pump-induced magnon mode that couples strongly to the Walker modes of the ferrimagnet. This anticrossing inherits an excellent tunability from the pump, which allows us to control the anticrossing via the pump power, frequency, and waveform. Further, we realize a remarkable functionality of this anticrossing, namely, a microwave frequency comb, in terms of the nonlinear interaction that mixes the pump and probe frequencies. Such a frequency comb originates from the magnetic dynamics and thereby does not suffer from the charge noise. The unveiled hybrid magnonics driven away from its equilibrium enriches the utilization of anticrossing for coherent information processing.

Abstract
BACKGROUND/PURPOSE The signaling mechanisms for Porphyromonas gingivalis lipopolysaccharide (PgLPS)-induced inflammation in human dental pulp cells are not fully clarified. This in vitro study aimed to evaluate the involvement of phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) pathway in PgLPS-induced pulpal inflammation. METHODS Human dental pulp cells (HDPCs) were challenged with PgLPS with or without pretreatment and coincubation with a PI3K/Akt inhibitor (LY294002). The gene or protein levels of PI3K, Akt, interleukin (IL)-6, IL-8, alkaline phosphatase (ALP), osteocalcin and osteonectin were analyzed by reverse transcription polymerase chain reaction (PCR), real-time PCR, western blotting, and immunofluorescent staining. In addition, an enzyme-linked immunosorbent assay was used to analyze IL-6 and IL-8 levels in culture medium. RESULTS In response to 5 μg/ml PgLPS, IL-6, IL-8, and PI3K, but not Akt mRNA expression of HDPCs, was upregulated. IL-6, IL-8, PI3K, and p-Akt protein levels were stimulated by 10-50 μg/ml of PgLPS in HDPCs. PgLPS also induced IL-6 and IL-8 secretion at concentrations higher than 5 μg/ml. Pretreatment and co-incubation by LY294002 attenuated PgLPS-induced IL-6 and IL-8 mRNA expression in HDPCs. The mRNA expression of ALP, but not osteocalcin and osteonectin, was inhibited by higher concentrations of PgLPS in HDPCs. CONCLUSION P. gingivalis contributes to pulpal inflammation in HDPCs by dysregulating PI3K/Akt signaling pathway to stimulate IL-6 and IL-8 mRNA/protein expression and secretion. These results are useful for understanding the pulpal inflammation and possible biomarkers of inflamed pulp diagnosis and treatment.

Abstract
Background/purpose The objective structured clinical examination (OSCE) is a test designed to test technical, clinical, and practical competency in medicine teaching. This study tried to evaluate the influencing factors of the computer-based tests (CBT) results for dental students. Materials and methods The 32 5th-year dental students of the dental school of National Taiwan University (NTU) joined preclinical CBT. The contents of CBT included clinical knowledge and practical skills of nine dental specialties. Twenty single-choice questions were played with the PowerPoint 2016 on a desktop, and the playing time for each question was 30 s. Several factors including the gender, age, and dental student admission ways (with or without the skill tests) were evaluated. Also, the comparison between the clerk's grade and CBT scores of nine dental specialties was performed. The students also filled the feedback questionnaire about the examination questions and suggestions for the CBT. Results There were no significant differences in the mean CBT scores between male and female dental students, between two groups of dental students with or without the skill tests in the admission process, and among three different age groups of dental students. The clerk's scores were not directly related to the CBT scores. Conclusion The CBT has been well-intentioned in dental education since 2022 in Taiwan. The CBT results revealed that the conjunction of knowledge from the textbook and clinical observation should be enhanced. The guideline should be established to integrate CBT into preclinical education and promote the performance of clinical work of dental students.

A total of 80 New Zealand White rabbits were used and 34 hearts without drug treatment were defined as control group A, these hearts were then treated with IKATP opener pinacidil, defined as pinacidil group A. Then, 27 hearts from pinacidil group A were selected to receive combined perfusion with sodium channel inhibitors or quinidine, a traditional drug used to treat short QT syndrome, including ranolazine combined group (n=9), mexiletine combined group (n=9), and quinidine combined group (n=9). Nineteen out of the remaining 46 New Zealand rabbits were selected as control group B (no drug treatments, n=19), and then treated with pinacidil, defined as pinacidil group B (n=19). The remaining 27 rabbits were treated with sodium inhibitors or quinidine alone, including ranolazine alone group (n=9), mexiletine alone group (n=9), and quinidine alone group (n=9). Electrocardiogram (ECG) physiological parameters of control group A and pinacidil group A were collected. In control group B and pinacidil group B, programmed electrical stimulation was used to induce ventricular arrhythmias and ECG was collected. ECG physiological parameters and ventricular arrhythmia status of various groups were analyzed. The concentrations of pinacidil, ranolazine, mexiletine and quinidine used in this study were 30, 10, 30 and 1 μmol/L, respectively. Results: Compared with control group A, the QT interval, 90% of the repolarization in epicardial and endocardial monophasic action potential duration (MAPD90-Epi, MAPD90-Endo) was shortened, the transmural dispersion of repolarization (TDR) was increased, and the effective refractor period (ERP) and post-repolarization refractoriness (PRR) were reduced in pinacidil group A (all P<0.05). Compared with the pinacidil group A, MAPD90-Epi, MAPD90-Endo, QT interval changes were reversed in quinidine combined group and mexiletine combined group (all P<0.05), but not in ranolazine combined group. All these three drugs reversed the pinacidil-induced increases of TDR and the decreases of ERP and PRR. The induced ventricular arrhythmia rate was 0 in control group B, and increased to 10/19 (χ2=13.6, P<0.05) in pinacidil group B during programmed electrical stimulation. Compared with the pinacidil group B, incidences of ventricular arrhythmia decreased to 11% (1/9), 11% (1/9) and 0 (0/9) (χ2=4.5, 4.5, 7.4, P<0.05) respectively in ranolazine group, mexiletine group and quinidine group. Conclusions: Inhibition of late sodium current does not increase but even decreases the risk of malignant arrhythmia in hearts with a shortened QT interval. The antiarrhythmic mechanism might be associated with the reversal of the increase of TDR and the decrease of refractoriness (including both ERP and PRR) of hearts with shortened QT interval.

Abstract
Objective: To evaluate the bladder function and sleep pattern in the children with primary mono-symptomatic nocturnal enuresis (PMNE) by the polysomnography (PSG) and ambulatory urodynamic monitoring (AUM). Methods: From October 2019 to October 2021, forty-three patients with PMNE were selected as PMNE group from the First Affiliated Hospital of Zhengzhou University and further subdivided into the severe PMNE group (enuresis>4 times/week) and the non-severe PMNE group (enuresis times 4 times/week) according to the severity. The conventional urodynamics (CUD), AUM, and PSG examinations and bladder diary were completed in the PMNE group. The control group consisted of 23 children with normal PSG findings and without the lower urinary tract symptoms. Results: The severe PMNE group included 9 males and 14 females, aged(12.1±3.2)years, and nocturnal enuresis number per week is 6.7±1.7. The non-severe PMNE group included 9 males and 11 females, aged(12.0±3.4)years, and nocturnal enuresis number per week is 2.3±1.0. The incidences of nocturnal polyuria and the reduction in maximum bladder capacity in the PMNE group was 34.9% and 11.6%, respectively. The incidence and frequency of detrusor overactivity (DO) in the severe PMNE group were significantly higher than those in the non-severe PMNE group [78.3% vs 45.0%, (5.5±1.8) times/h vs (3.4±1.0) times/h, respectively, all P<0.05]. It was found by the PSG that the severe PMNE group had significantly higher cortical arousal index, apnea hypopnea index (AHI), and percentage of N1+N2 phase in total sleep time, compared with the control group[(58.6±9.8)% vs (49.3±9.5)%, (9.4±4.4) times/h vs (3.1±1.5) times/h, (2.7±0.9) times/h vs (0.9±0.7) times/h] (all P<0.05). While the sleep efficiency of the severe PMNE group was substantially lower than that of the non-severe PMNE group [(86.4±4.3)% vs (91.0±3.9)%], the cortical arousal index and AHI were significantly greater than those of the non-severe PMNE group[(9.4±4.4) times/h vs (5.7±3.2) times/h, (2.7±0.9) times/h vs (1.9±0.7) times/h] (all P<0.05). In the PMNE group, there were positive correlations between cortical arousal index and nocturnal DO frequency or AHI (r=0.705, 0.765, P=0.001). Conclusions: Children with PMNE have nocturnal bladder dysfunction and abnormal sleep pattern, and there is a certain correlation between them. PSG and AUM are necessary for the evaluation and treatment of children with PMNE.

Abstract
Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ2=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Abstract
Objective: To investigate the genetic characteristics of varicella zoster virus (VZV) in Shandong province from 2020 to 2021. Methods: From April 2020 to December 2021, 85 herpes fluid samples from suspected varicella patients in Shandong province were collected. The qPCR was used to detect viral DNA and screen suspected samples. Six single nucleotide polymorphisms (SNPs) of ORF22 fragment and ORF38 fragment in positive samples were examined via PCR and Sanger sequencing to identify the viral genotypes. Four SNPs of ORF38 and ORF62 were examined to identify the vaccine and wild-type strains. The sequences were analyzed with Sequencher and MEGA7 software, using the VZV reference strain sequences from GenBank. Results: In the 85 samples suspected of varicella, 80 were VZV positive and wild-type strains belonging to Clade 2. Compared with clade 2 representative strains, the nucleotide and amino acid similarities of ORF22 fragment were 99.5%-100% and 98.5%-100%, respectively. SD20-1, SD20-5, SD20-6, SD20-8, SD20-9, SD20-10, SD20-11, SD20-12, SD20-13, SD20-30 and SD20-31 had a A➝G nucleotide mutation at 37990, causing amino acid change from glutamine to arginine. SD21-1 had a C➝A nucleotide mutation at 38059, causing threonine to asparagine during coding. Conclusions: From 2020 to 2021, all VZV strains in Shandong province are the wild-type strains belonging to Clade 2.

Abstract
Objective: To analyze the significance of HBV DNA below the lower detection limit of HBV RNA levels after long-term nucleos(t)ide analogues (NAs) antiviral therapy in patients with hepatitis B virus cirrhosis. Methods: 97 cases with hepatitis B virus cirrhosis treated with NAs antiviral therapy for at least 3 years between May 2018 to July 2019 were selected. High-sensitivity HBV DNA (<20 IU/ml), alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyltransferase (GGT), HBsAg, HBeAg and HBV RNA at least twice every 6 months were detected. According to Child-Pugh classification, HBeAg, HBsAg level, and HBV RNA level intergroup comparison was performed. Rank sum test, χ2 test and linear regression analysis were performed on the data. Results: Compared with the HBV RNA level of child-Pugh class A patients, the HBV RNA level of Child-Pugh class B+C patients were significantly higher [4.1 (0,4.9) log10 copies/ml and 2.0 (0,3.5) log10 copies/ml], and the difference was statistically significant (Z=2.370, P<0.05). According to different HBeAg levels, they were divided into HBeAg positive and negative group, and the quantitative comparison of HBV RNA levels between the two groups were 2.0 (0, 4.5) log10 copies/ml and 1.0 (1.0, 2.0) log10 copies/ml, respectively, and the difference was statistically significant (Z=3.233, P<0.05). According to different HBsAg levels, they were divided into three groups: HBsAg≤100 IU/ml, 100<HBsAg<1 000 IU/ml, and HBsAg≥1 000 IU/ml, and the quantitative comparison of HBV RNA levels among the three groups were 0 (0, 2.0) log10, 2.0 (0,4.6) log10, and 2.2 (2.0, 4.7) log10 copies/ml, respectively, and the difference was statistically significant (H=11.265, P<0.05). Gender, age, ALT, AST, GGT, HBsAg, and HBeAg were included for linear regression analysis, and the HBsAg and AST levels were correlated with HBV RNA quantification (P<0.05). Adverse events occurrence during 1-year follow-up were recorded. 19 (31.7%) out of 60 cases had adverse events with detectable HBV RNA, and 3 (8.1%) out of 37 cases had adverse events with undetectable HBV RNA, and the difference was statistically significant (χ2=7.24, P<0.05). Conclusion: HBV RNA can still be detected after HBV DNA falls below the detection limit in patients with hepatitis B virus cirrhosis treated with long-term NAs antiviral therapy. HBV RNA quantification level is higher in patients with Child Pugh class B and C. Patients with detectable HBV RNA has higher proportion of adverse events, and AST and HBsAg levels may be correlated with serum HBV RNA.

Abstract
Objective: To evaluate whether underdilated stent could reduce the occurrence of hepatic encephalopathy (HE) after transjugular intrahepatic portosystemic shunt (TIPS) creation. Methods: A total of 197 patients with decompensated liver cirrhosis, who had underwent TIPS creation at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, were analyzed retrospectively, including 110 males and 87 females with age 25-79 (54±11) years old. Uncovered and covered stents with 8 mm diameter were implanted in all subjects, and then dilated by balloon catheters with 6 mm or 8 mm diameter. The patients were divided into two groups, including underdilated group (6 mm, n=105) and control group (8 mm, n=92).Kaplan-Meier curves were used to illustrate cumulative rate of HE, and the differences were assessed with the log-rank test. Multivariate analyses with a Cox regression model were conducted to explore the risk factors for HE. Results: During a median follow-up period of 29 (12-54) months, 16 (15.2%) patients developed HE in the underdilated group and 27 (29.3%) patients in the control group. There was a significant difference in the cumulative rate of HE (P=0.014), but no statistical differences were found in terms of variceal rebleeding, shunt dysfunction and survival between the two groups (P=0.608, P=0.659, P=0.968). In multivariated analysis, group assignment (underdilated vs. control, HR=0.291, 95%CI 0.125-0.674, P=0.004) was identified as an independent risk factor for HE after TIPS creation. Conclusion: Underdilated TIPS could reduced the risk of HE compared with completely dilated TIPS, with comparable risk of variceal rebleeding, shunt dysfunction and mortality. And it is worthy of applying this technique to a large sample of patients in clinical practice.

Abstract
Objective: This study aimed to look into the clinical characteristics and prognosis of patients with human immunodeficiency virus (HIV) -associated diffuse large B-cell lymphoma (DLBCL) . Methods: Retrospective review of the clinical data of 63 HIV-infected patients with DLBCL diagnosed at Chongqing University Cancer Hospital between July 2008 and August 2021. The Kaplan-Meier method was used to calculate survival curves, and the log-rank test method was used to compare survival between groups. The Cox proportional hazards model was used for multivariate analysis. Results: In 63 patients with HIV-associated DLBCL, 57 (90.5% ) were men, and the median age was 49 (23-87) years. The most common pathological subtype was the germinal center B-cell-like lymphoma (74.6% ) ; 46.0% (29/63) were combined with extranodal lesions. Seventeen of 63 (27.0% ) patients had large masses (≥7.5 cm) . Twenty of 63 (31.7% ) patients had B symptoms. The median CD4(+) T cell count was 203 (4-1022) ×10(6)/L. A total of 49% (25/51) patients had CD4(+) cell count <200×10(6)/L, 56.9% (33/58) had high (3-5) International Prognostic Index (IPI) scores, and 43.1% (25/58) had low (0-2) IPI scores. Further, 78% (46/59) were diagnosed with Ann Arbor Stage Ⅲ/Ⅳ, and 25.4% (16/63) didn't receive chemotherapy. A total of 22.2% (14/63) of patients received less than four cycles of chemotherapy, and 52.4% (33/63) received four or more cycles of chemotherapy. Among patients undergoing chemotherapy, 61.7% (29/47) received R-CHOP-like regimens, and 38.3% (18/47) used CHOP-like regimens. The 1-, 2-, 3-, and 5-year overall survival (OS) rates were 65.0% , 53.8% , 47.1% , and 43.5% , respectively. Univariate analysis revealed that age ≥ 60 years (P=0.012) , Eastern Cooperative Oncology Gruop Performance Status (ECOG-PS) score 2-4 points (P=0.043) , IPI score 3-5 points (P=0.001) , β(2)-MG elevation (≥5.5 mg/L) (P=0.007) , and systemic chemotherapy cycles less than four times (P<0.001) were the negative prognostic factors affecting the OS of patients. The Cox multivariate analysis depicted that age ≥60 years (HR=2.272, 95% CI 1.110-4.651, P=0.025) , IPI score 3-5 points (HR=3.562, 95% CI 1.794-7.074, P<0.001) , ECOG-PS score 2-4 points (HR=2.675, 95% CI 1.162-6.153, P=0.021) , and number of cycles of chemotherapy<4 (HR=0.290, 95% CI 0.176-0.479, P<0.001) were independent risk factors for adverse prognosis of OS. Conclusion: HIV-associated DLBCL is the most common HIV-related tumor, is most commonly seen in men, and has a high 1-year mortality rate. Chemotherapy combined with antiretroviral therapy can improve patient prognosis.

Abstract
This study aimed to investigate influence of ultrasonic treatment on physicochemical and antioxidant properties of mung bean protein hydrolysate (MPH). Physicochemical properties of MPH were evaluated by Tricine-SDS-PAGE, particle size distribution, fourier transform infrared spectroscopy (FTIR) and fluorescence spectroscopy, among others. Radicals scavenging activities of ABTS, hydroxyl, superoxide anion, Fe2+ chelating ability and reducing power characterized antioxidant activities of MPH. MPH contained four bands of 25.6, 12.8, 10.6 and 4.9 kDa, in which 4.9 kDa was the most abundant. Ultrasonic treatment increased the contents of aromatic and hydrophobic amino acids in MPH. Ultrasonic treatment decreased the content of α-helix of MPH and increased β-sheet and β-turn compared to MPH. MPH-546 W (ultrasonic treatment 546 W, 20 min) had the lowest average particle size (290.13 nm), zeta potential (-36.37 mV) and surface hydrophobicity (367.95 A.U.). Antioxidant activities of ultrasonicated-MPH increased with the ultrasonic power, achieving the lowest IC50 (mg/mL) of 0.1087 (ABTS), 1.796 (hydroxyl), 1.003 (superoxide anion) and 0.185 (Fe2+ chelating ability) in 546 W power. These results indicated ultrasonic treatment would be a promising method to improve the antioxidant properties of MPH, which would broaden the application scope of MPH as bioactive components in the food industry.

Abstract
During intervertebral disc degeneration (IVDD), due to endplate calcification, diminished oxygen and nutrient concentrations and accumulated lactate are present in the microenvironment of the nucleus pulposus (NP). The disadvantages of 3D layered culture include uneven oxygen and nutrient gradients. In the present study, to mimic the in vivo microenvironment of the NP, a 5-layered 3D culture was constructed using clinical haemostatic gelatine sponges and developed as a NP degeneration (NPD) model. Subsequently, cell distribution as well as expression of NP chondrogenic markers (type II collagen and aggrecan), glycosaminoglycan (GAG) and degeneration markers [e.g. matrix metalloproteinase (MMP) 3] were measured from the top to the bottom layer. However, in a single NP-cell-loaded disc model, the chondrogenic potency in the middle or bottom layer was higher than that in the top layer. To further study the mechanism underlying the degeneration of NP cells in this NPD model, the contribution of secreted metabolites was examined. Lactate identified in the supernatant modulated GAG accumulation and MMP3 expression. Inhibition of lactate influx by the monocarboxylate transporter (MCT)-1 inhibitor, AZD3965, reversed the effect of lactate on GAG accumulation and MMP3 expression and further improved NP cell degeneration in the NPD model. Thanks to the homogenous expression of lactate in the model, it was possible to further identified that the combination of lactate and hypoxia enhanced MMP3 expression. Taken together, multilayered cell-loaded sponges, with oxygen and nutrient gradients as well as lactate accumulation, can represent a 3D multilayered NPD model for exploring potential agents for IVDD.

Methods: The clinical manifestations including fever, rash, systems involvement as well as laboratory results and genotypic characteristics of 35 children with inflammasomopathies diagnosed by the Department of Pediatrics, Peking Union Medical College Hospital, from January 1, 2008 to December 31, 2020 were analyzed retrospectively. Results: A total of 35 cases of inflammasomopathies were diagnosed, and 20 of them were boys while 15 were girls. Inflammasomopathies patients have early onset, the age of onset as well as diagnostic age were 1 (0,7) and 7 (3,12), respectively. Among those patients, 10 had familial mediterranean fever, 3 had mevalonate kinase deficiency, 15 cases had NLRP3 gene associated autoinflammatory disease, 4 cases had NLRP12-associated autoinflammatory disease, 2 cases had familial cold autoinflammatory syndrome 3, and 1 case had familial cold autoinflammatory syndrome 4. A total of 34 cases (97%) showed recurrent fever, 27 cases (77%) had skin rashes, while 11 cases (31%), 10 cases (29%), and 8 cases (23%) were presented with lymphadenopathy, hepatosplenomegaly and growth retardation, respectively. In terms of systemic involvement, there were 18 cases (51%), 12 cases (34%), 8 cases (23%), and 5 cases (14%) with skeletal, neurological, auditory, and renal involvement, respectively. Central nervous system involvement was seen only in NLRP3 gene associtated autoinflammatory diseases (12 cases), sensorineural deafness was seen in NLRP3 gene associtated autoinflammatory diseases (6 cases) and NLRP12 gene associated autoinflammatory diseases (2 cases), and abdominal pain was observed in familial Mediterranean fever (5 cases), mevalonate kinase deficiency (1 case) and NLRP12 gene related autoinflammatory diseases (1 case). In the acute inflammatory phase, the acute phase reactants (erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP)) of 35 cases (100%) were significantly increased. There were 21 cases received ferritin examination, and only 4 cases (19%) showed an increase of it. In terms of autoantibodies, among all 35 patients, 4 cases (11%) were positive for antinuclear antibodies (ANA). Conclusions: Fever, skin rash, and skeletal manifestations are the most common clinical features, accompanied with increased CRP and ESR, and negative results of autoantibodies such as ANA. The clinical manifestations of those diseases are complex and diverse, and it is prone to delayed diagnosis and treatment.

Abstract
Background/purpose In 1906, there was a dental treatment room established in the department of surgery of Taipei Hospital to introduce modern dental services to Taiwan. It is undoubtedly the earliest hospital dentistry in Taiwan. This study tried to assess the dental manpower and treated dental diseases in Taipei Hospital, and hence to explore the appearance of Taiwan's early hospital dentistry. Materials and methods This study utilized the secondary data analysis to evaluate the dental manpower and treated dental diseases of dental outpatients in the 27th Annual Report of Taipei Hospital (Taisho 12th year or 1923). Results Our results found that there were 3 dentists and one dental technician in the dental department of Taipei Hospital in 1923. These 3 dentists totally treated 3 inpatients and 1759 outpatients with 4511 outpatient visits (1959 for male patients and 2552 for female patients) in that year. Dental caries and retained root were the two most common dental diseases in Japanese and Taiwanese dental outpatients, and followed in a descending order by missing tooth, pulp necrosis, and pulpitis for Japanese outpatients as well as pulpitis, suppurative periodontitis, and acute or chronic periodontitis for Taiwanese outpatients. Conclusion We conclude that the dentistry of Taipei Hospital in 1923 does have a modern form of dentistry with 3 dentists and one dental technician. Its dental patients are mainly Japanese and minorly Taiwanese. Moreover, the treated dental diseases are mainly tooth diseases for Japanese outpatients and both tooth and periodontal diseases for Taiwanese outpatients.

Abstract
Background: Most patients who take antihypertensive medications continue taking them on
the morning of surgery and during the perioperative period. However, growing
evidence suggests this practice may contribute to perioperative hypotension
and a higher risk of complications. This protocol describes an acute kidney
injury substudy of the Perioperative Ischemic Evaluation-3 (POISE-3) trial,
which is testing the effect of a perioperative hypotension-avoidance
strategy versus a hypertension-avoidance strategy in patients undergoing
noncardiac surgery. Objective: To conduct a substudy of POISE-3 to determine whether a perioperative
hypotension-avoidance strategy reduces the risk of acute kidney injury
compared with a hypertension-avoidance strategy. Design: Randomized clinical trial with 1:1 randomization to the intervention (a
perioperative hypotension-avoidance strategy) or control (a
hypertension-avoidance strategy). Intervention: If the presurgery systolic blood pressure (SBP) is <130 mmHg, all
antihypertensive medications are withheld on the morning of surgery. If the
SBP is ≥130 mmHg, some medications (but not angiotensin receptor blockers
[ACEIs], angiotensin receptor blockers [ARBs], or renin inhibitors) may be
continued in a stepwise manner. During surgery, the patients’ mean arterial
pressure (MAP) is maintained at ≥80 mmHg. During the first 48 hours after
surgery, some antihypertensive medications (but not ACEIs, ARBs, or renin
inhibitors) may be restarted in a stepwise manner if the SBP is ≥130
mmHg. Control: Patients receive their usual antihypertensive medications before and after
surgery. The patients’ MAP is maintained at ≥60 mmHg from anesthetic
induction until the end of surgery. Setting: Recruitment from 108 centers in 22 countries from 2018 to 2021. Patients: Patients (~6800) aged ≥45 years having noncardiac surgery who have or are at
risk of atherosclerotic disease and who routinely take antihypertensive
medications. Measurements: The primary outcome of the substudy is postoperative acute kidney injury,
defined as an increase in serum creatinine concentration of either ≥26.5
μmol/L (≥0.3 mg/dL) within 48 hours of randomization or ≥50% within 7 days
of randomization. Methods: The primary analysis (intention-to-treat) will examine the relative risk and
95% confidence interval of acute kidney injury in the intervention versus
control group. We will repeat the primary analysis using alternative
definitions of acute kidney injury and examine effect modification by
preexisting chronic kidney disease, defined as a prerandomization estimated
glomerular filtration rate <60 mL/min/1.73 m2. Results: Substudy results will be analyzed in 2022. Limitations: It is not possible to mask patients or providers to the intervention;
however, objective measures will be used to assess acute kidney injury. Conclusions: This substudy will provide generalizable estimates of the effect of a
perioperative hypotension-avoidance strategy on the risk of acute kidney
injury.

Abstract
A total of 16 detrusor hyperactivity with impaired contractility (DHIC) patients who received 12 weeks remote variable frequency stimulation (VFS) were enrolled at the First Affiliated Hospital of Zhengzhou University from September 2020 to February 2021. The voiding diary, symptom score scales and incidence of complications were completed and recorded at baseline, constant frequency stimulation (CFS) and VFS phases. Compared with the CFS phase, voiding times, urge incontinence times and daily catheterization volume were reduced; average voiding amount and functional bladder capacity increased; and the quality of life score and mental health questionnaire assessment were improved in the VFS phase(all P<0.05). In the end, among all 16 patients, there were 14 whose symptoms had improved, and there were no new complications such as pain or infection at the implantation site, electrode displacement, and electric shock sensation in the stimulation area. VFS-SNM can not only improve the DHIC patients' lower urinary tract symptoms during storage and urination period, but also improve the patients' quality of life and satisfaction of the therapy.

Abstract
To investigate the effect of Er:YAG laser treatment on lipopolysaccharide (LPS) clearance and fibroblast adhesion on titanium disks. Grade IV titanium discs (n = 216) were used and allocated to 6 groups. Group 1 was the negative control without Porphyromonas gingivalis inoculation. Discs in Groups 2-6 were incubated with P. gingivalis to form a biofilm. Group 3 received 0.12% chlorhexidine irrigation and Group 4 received titanium curettage to remove the biofilm. Group 5 was treated with Er:YAG laser irradiation and Group 6 was treated with titanium curettage plus Er:YAG laser irradiation. The contact angle and surface roughness were measured after the various treatments. The surface microstructure and residual bacteria were examined using scanning electron microscopy and confocal laser scanning microscopy, respectively. Residual LPS was examined using a limulus amoebocyte lysate assay and human gingival fibroblast adhesion was quantified using fluorescent microscopy. Curettage plus Er:YAG laser irradiation was the most effective method for removing bacteria and LPS. No significant difference in the amount of fibroblast adhesion was found between the control and Group 6. Combined use of Er:YAG laser irradiation and curettage optimizes LPS clearance and fibroblast adhesion on titanium discs.

Abstract
Temozolomide (TMZ) resistance is an important cause of clinical treatment failure and poor prognosis in gliomas. Increasing evidence indicates that cancer-derived exosomes contribute to chemoresistance; however, the specific contribution of glioma-derived exosomes remains unclear. The aim of this study was to explore the role and underlying mechanisms of exosomal macrophage migration inhibitory factor (MIF) on TMZ resistance in gliomas. We first demonstrated that MIF was upregulated in the exosomes of TMZ-resistant cells, engendering the transfer of TMZ resistance to sensitive cells. Our results indicated that exosomal MIF conferred TMZ resistance to sensitive cells through the enhancement of cell proliferation and the repression of cell apoptosis upon TMZ exposure. MIF knockdown enhanced TMZ sensitivity in resistant glioma cells by upregulating Metalloproteinase Inhibitor 3 (TIMP3) and subsequently suppressing the PI3K/AKT signaling pathway. Additionally, exosomal MIF promoted tumor growth and TMZ resistance of glioma cells in vivo, while IOS-1 (MIF inhibitor) promotes glioma TMZ sensitive in vivo. Taken together, our study demonstrated that exosome-mediated transfer of MIF enhanced TMZ resistance in glioma through downregulating TIMP3 and further activating the PI3K/AKT signaling pathway, highlighting a prognostic biomarker and promising therapeutic target for TMZ treatment in gliomas.
