Abstract
Influenza A virus (IAV) poses a threat to patients receiving immunosuppressive medications since they are more susceptible to infection with severe symptoms, and even death. Understanding the direct effects of immunosuppressants on IAV infection is critical for optimizing immunosuppression in these patients who are infected or at risk of influenza virus infection. We profiled the effects of 10 immunosuppressants, explored the antiviral mechanisms of immunosuppressants, and demonstrated the combined effects of immunosuppressants with the antiviral drug oseltamivir in IAV-infected cell models. We found that mycophenolic acid (MPA) strongly inhibits viral RNA replication via depleting cellular guanosine pool. Treatment with 6-Thioguanine (6-TG) promoted viral protein degradation through a proteasomal pathway. Filgotinib blocked mRNA splicing of matrix protein 2, resulting in decreased viral particle assembly. Furthermore, combined treatment with immunosuppressants and oseltamivir inhibits IAV viral particle production in an additive or synergic manner. Our results suggest that MPA, 6-TG, and filgotinib could be the preferential choices for patients who must take immunosuppressants but are at risk of influenza virus infection.

Abstract
Polyprenols (PPs) are compounds with excellent biological activities and are applied in food, pharmaceutical, and cosmetic industries. However, its strong non-polar nature makes it difficult to separate with many saturated impurities (such as saturated fatty acids) extracted together. Complexation extraction is an effective method for separating saturated and polyunsaturated compounds. In this study, mesoporous silica MCM-41 was modified by imidazole-based ionic liquids (IL) followed by coating these MCM-41-supported IL compounds with silver salt to construct π-complexing adsorbent (AgBF4/IL•MCM-41) to enrich PPs from Ginkgo biloba leaves (GBL) extract. The mesoporous π-complexing sorbent was characterized by small-angle X-ray scattering (SAXS), FTIR, and nitrogen adsorption-desorption. The effect of the ratio of silver salt to IL•MCM-41 on the adsorption capacity of polyprenols from GBL was compared, and the dosage of AgBF4 was determined to be 1.5 mmol/g IL•MCM-41. Adsorption isotherms and kinetics indicate that the π-complexing adsorbent has excellent PPs adsorption performance (153 mg/g at 30 °C) and a fast adsorption rate (the time to reach adsorption equilibrium is 210 s). The PPs were separated using the fixed bed after treatment for only one cycle with AgBF4/IL•MCM-41, and the content of PPs in the product was increased from 38.54% to 70.2%, with a recovery rate of 86.6%. The π-complexing adsorbent showed excellent reusability for ≥3 adsorption-desorption cycles.

Abstract
Objective: To explore the feasibility and efficacy for the dissection and ligation of the superior laryngeal artery in endoscopic surgery for hypopharyngeal cancer. Methods: Eight cadaveric heads were selected, and the laryngopharynxes were harvested. The positions of the superior laryngeal arteries entering the larynxes were dissected and observed under endoscopic vision, and their anatomical characteristics were summarized. Twenty-nine patients (all were male, aged 39-74 years old) with hypopharyngeal cancer who underwent transoral endoscopic surgery at the Department of Otorhinolaryngology Head and Neck Surgery of the Second Xiangya Hospital, Central South University from January 2018 to December 2019 were selected, and the patients were randomly divided into two groups by drawing lots, namely, the superior laryngeal artery was actively dissected and occluded during surgery in observation group (n=15) or not in control group (n=14). The differences in surgical time, bleeding volume, postoperative complications, and postoperative disease-free survival rate were compared between the two groups. Statistical analysis was conducted using SPSS 25.0 software. Results: The entry point of the superior laryngeal artery into the larynx was approximately at the level of the superior edge of the thyroid cartilage, and entered the larynx at the posterior one-third of the lateral wall of the pyriform fossa. The superior laryngeal artery might be determined through endoscopic exploration in all patients of observation group. The endoscopic surgery time [(40.00±7.56) minutes] and intraoperative bleeding volume [(24.00±8.28) ml] in the observation group were respectively less than those [(48.57±14.06) minutes and (42.86±15.41) ml] in the control group, and the differences were statistically significant (t=-2.064, P=0.049; t=-4.064, P=0.001). There was no case with postoperative bleeding in the observation group, but with one case of postoperative bleeding in the control group. Total disease free survival rate was 86.2% and there was no significant difference in disease free survival rates between the two groups during a follow-up period of at least 36 months (P=0.986). Conclusion: Dissection of the superior laryngeal artery during endoscopic surgery for hypopharyngeal cancer is feasible, and pre-management and occlusion of the superior laryngeal artery can effectively reduce intraoperative bleeding.

Abstract
BRISC (BRCC3 isopeptidase complex) is a deubiquitinating enzyme that has been linked with inflammatory processes, but its role in liver diseases and the underlying mechanism are unknown. Here, we investigated the pathophysiological role of BRISC in acute liver failure using a mice model induced by D-galactosamine (D-GalN) plus lipopolysaccharide (LPS). We found that the expression of BRISC components was dramatically increased in kupffer cells (KCs) upon LPS treatment in vitro or by the injection of LPS in D-GalN-sensitized mice. D-GalN plus LPS-induced liver damage and mortality in global BRISC-null mice were markedly attenuated, which was accompanied by impaired hepatocyte death and hepatic inflammation response. Constantly, treatment with thiolutin, a potent BRISC inhibitor, remarkably alleviated D-GalN/LPS-induced liver injury in mice. By using bone marrow-reconstituted chimeric mice and cell-specific BRISC-deficient mice, we demonstrated that KCs are the key effector cells responsible for protection against D-GalN/LPS-induced liver injury in BRISC-deficient mice. Mechanistically, we found that hepatic and circulating levels of TNF-α, IL-6, MCP-1, and IL-1β, as well as TNF-α- and MCP-1-producing KCs, in BRISC-deleted mice were dramatically decreased as early as 1 h after D-GalN/LPS challenge, which occurred prior to the elevation of the liver injury markers. Moreover, LPS-induced proinflammatory cytokines production in KCs was significantly diminished by BRISC deficiency in vitro, which was accompanied by potently attenuated NF-κB activation. Restoration of NF-κB activation by two small molecular activators of NF-κB p65 effectively reversed the suppression of cytokines production in ABRO1-deficient KCs by LPS. In conclusion, BRISC is required for optimal activation of NF-κB-mediated proinflammatory cytokines production in LPS-treated KCs and contributes to acute liver injury. This study opens the possibility to develop new strategies for the inhibition of KCs-driven inflammation in liver diseases.

Abstract
Methionine is indispensable for growth and meat formation in pigs. However, it is still unclear that increasing dietary sulphur-containing amino acid (SAA) levels using different methionine sources affects the growth performance and meat quality of barrows and gilts. To investigate this, 144 pigs (half barrows and half gilts) were fed the control (100% SAA, CON), DL-Methionine (125% SAA, DL-Met)-supplemented, or OH-Methionine (125% SAA, OH-Met)-supplemented diets during the 11-110 kg period. The results showed that plasma methionine levels varied among treatments during the experimental phase, with increased plasma methionine levels observed following increased SAA consumption during the 25-45 kg period. In contrast, pigs fed the DL-Met diet had lower plasma methionine levels than those fed the CON diet (95-110 kg). Additionally, gilts fed the DL-Met or OH-Met diets showed decreased drip loss in longissimus lumborum muscle (LM) compared to CON-fed gilts. OH-Met-fed gilts had higher pH45min values than those fed the CON or DL-Met diets, whereas OH-Met-fed barrows had higher L45min values than those fed the CON or DL-Met diets. Moreover, increased consumption of SAA, regardless of the methionine source, tended to decrease the shear force of the LM in pigs. In conclusion, this study indicates that increasing dietary levels of SAA (+25%) appeared to improve the meat quality of gilts by decreasing drip loss and increasing meat tenderness.

Abstract
BACKGROUND Ginkgo biloba leaves contain beneficial flavonoids, bilobalide (BB), and ginkgolides. However, the toxic ginkgolic acid (GA) limit its application. In this study, various traditional processing methods were used to prepare G. biloba leaf tea (GBLT), including white tea, black tea, dark tea, green tea, and freeze-dried as control, followed by investigations of their effects on quality, antioxidant capacity, bioactive components, and cytotoxicity of the tea products. RESULTS Results showed that different processing methods significantly impact the tea products' quality indexes and the principal component analysis (PCA) and hierarchical cluster analysis (HCA) corroborated it. White tea had the highest total sugar (TS) and GA content and the most potent cytotoxicity on HepG2 cells. However, TS and GA content and the cytotoxicity of GBLT markedly decreased during fermentation and fixation. Moreover, white tea possessed higher total phenolic content (TPC), total flavonoid content (TFC), and more vigorous antioxidant activities than green tea, black tea, and dark tea. Terpene trilactones value was stable, but different catechins contents fluctuated according to the manufacturing process of different GBLTs. Among the four GBLTs, dark tea combining fixation and fermentation had the lowest GA content and cytotoxicity, less bioactive components reduction, appropriate quality, and stronger flavor. CONCLUSION These findings demonstrate that fixation and fermentation help reduce GAs during the manufacturing of GBLT. However, their ability to retain bioactive substances needs further optimization in future studies. © 2023 Society of Chemical Industry.

Abstract
Objective: To compare the characteristics of children's pulmonary tuberculosis (PTB) cases reported from 2019 to 2021 before and during the implementation of the Action Plan to Stop Tuberculosis. Methods: Based on the reported incidence data and population data of child pulmonary tuberculosis (PTB) notified to the Chinese Center for Disease Control and Prevention (CDC) Tuberculosis Information Management System (TBIMS) from 2019 to 2021, the population information and clinically relevant information in different years were compared. Results: From 2019 to 2021, the reported cases of PTB in children were 363, 664 and 655, respectively. The number of reported cases increased significantly. The median age of the cases in children increased from 10.4 years in 2019 to 11.7 years in 2021 (P=0.005) over a three-year period. The etiological positive rate increased significantly from 11.6% (42/363) in 2019 to 32.2% (211/655) in 2021 (P<0.001). The positive rate of molecular testing increased most significantly, which became the main means of etiological detection and accounted for 16.7% (7/42), 62.0% (57/92) and 75.4% (159/211) of the children with positive etiological results, respectively. The resistance rates of isoniazid and rifampicin were analyzed in children with PTB who underwent drug sensitivity tests. The results showed that the resistance rates of isoniazid and/or rifampicin were 2/9, 3.9% (2/51) and 6.7% (11/163), respectively, with an average of 6.7% (15/223) over three years. The median patients' delay was 27 (12, 49) days in 2019. It was reduced to 19 (10, 37) days in 2020 and 15 (7, 34) days in 2021, both significantly lower than 2019 (P=0.009 and 0.000 2, respectively). Conclusion: From 2019 to 2021, the reported numbers of children with PTB and children with positive etiological results increase significantly in Liangshan Prefecture, while the diagnosis delay of patients significantly reduces.

Abstract
Rotavirus remains a major cause of diarrhea among 5-y-old children, and vaccination is currently the most effective and economical measure. We conducted a randomized, double-blind, placebo-controlled phase II clinical trial designed to determine the dosage, immunogenicity, and safety profile of a novel hexavalent rotavirus vaccine. In total, 480 eligible healthy infants, who were 6-12 weeks of age at the time of randomization were randomly allocated (1:1:1) to receive 105.5 focus-forming unit (FFU) or 106.5FFU of vaccine or placebo on a 0, 28 and 56-d schedule. Blood samples were collected 28 d after the third dose to assess rotavirus immunoglobulin A (IgA) antibody levels. Adverse events (AEs) up to 28 d after each dose and serious adverse events (SAEs) up to 6 months after the third dose were recorded as safety measurements. The anti-rotavirus IgA seroconversion rate of the vaccine groups reached more than 70.00%, ranging from 74.63% to 76.87%. The postdose 3 (PD3) geometric mean concentrations (GMCs) of anti-rotavirus IgA among vaccine recipients ranged from 76.97 U/ml to 84.46 U/ml. At least one solicited AE was recorded in 114 infants (71.25%) in the high-dose vaccine group, 106 infants (66.25%) in the low-dose vaccine group and 104 infants (65.00%) in the placebo group. The most frequently solicited AE was fever. The novel oral hexavalent rotavirus vaccine was safe and immunogenic in infants support the conclusion to advance the candidate vaccine for phase 3 efficacy trials.

Abstract
To seek new high energetic materials, N-methylene-C-bridged nitrogen-rich heterocycle 1-((4,5-diamino-4H-1,2,4-triazol-3-yl)methyl)-1H-1,2,4-triazol-3,5-diamine (DATMTDA) (2) was first synthesized, and two copper coordination compounds ([Cu12(OH)4(ClO4)4(H2O)4(DATMTDA)12](ClO4)16·12H2O (3) and [Cu3(OH)(ClO4)(DATMTDA)3](ClO4)3(NO3) (4)) based on 2 were formed by introducing different anions. These compounds were characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction analysis. The crystal structures of compounds 3 and 4 are similar and crystallize in monoclinic systems with the P21/c space group, while the central copper atoms show different coordination behaviors. However, the structure of compounds 3 and 4 is analogous to a three dimensional structure owing to the O atom of OH-, forming coordinate bonds with three copper cations. The NBO charge of 2 was calculated using density functional theory to understand its coordination modes. The Hirshfeld surface calculation reveals that 3 and 4 have strong intermolecular interactions. The thermal decomposition processes, non-isothermal kinetics, and enthalpies of formation and sensitivities of these compounds were investigated. By introducing one NO3- of compound 4 to replace one ClO4- in compound 3, compound 4 shows lower density and lower decomposition peak temperature but lower sensitivity and a higher formation enthalpy than compound 3. The complex 4 possesses an outstanding catalytic effect for the decomposition of AP than that of complex 3. The results illustrate the possibility of introducing various anions into energetic coordination compounds for the regulation of energetic materials.

Abstract
Objective: To evaluate the immunogenicity and safety of revaccination of 23-valent pneumococcal polysaccharide vaccine (PPV23) in elderly people aged ≥60 years. Methods: The elderly aged ≥60 years with 1 dose of PPV23 vaccination were selected as revaccination group and those without history of pneumococcal vaccine immunization were selected as the first vaccination group. One dose of PPV23 was administered to both groups, and the first blood samples were collected before vaccination while the second blood samples were collected on day 28-40 after vaccination. ELISA was used to detect the concentrations of anti-specific serotype Streptococcus pneumoniae podocyte polysaccharide immunoglobulin G, and the safety of the vaccination was evaluated after 30 days. Results: The geometric mean concentration (GMC) of antibody to 23 serotypes before the vaccination (0.73-13.73 μg/ml) was higher in revaccination group than in the first vaccination group (0.39-7.53 μg/ml), the GMC after the vaccination (1.42-31.65 μg/ml) was higher than that before the vaccination (0.73-13.73 μg/ml) in the revaccination group, and the GMC after the vaccination (1.62-43.76 μg/ml) was higher than that before the vaccination (0.39-7.53 μg/ml) in the first vaccination group; the geometric mean growth multiple in revaccination group (2.16-3.60) was lower than that in the first vaccination group (3.86-16.13); The mean 2-fold antibody growth rate was lower in revaccination group (53.68%, 95%CI: 52.30%-55.06%) than in the first vaccination group (93.16%, 95%CI: 92.18%- 94.15%), all differences were significant (P<0.001). After the vaccination, 13 serotypes of GMC were higher in the first vaccination group than in revaccination group (P<0.001), the differences were not significant for 10 serotypes of GMC (P>0.05). The incidence of local adverse reaction was 19.20% and 13.27% in revaccination group and the first vaccination group, respectively (P=0.174). Conclusions: The antibody level in ≥60 years people who received one dose of PPV23 after a 5-year interval was still higher than that in unvaccinated people. The antibody level decreased after 5 years of the first vaccination, and the antibody level could be rapidly increased by one more dose vaccination, but the overall immune response was lower than that of the first vaccination; revaccination with PPV23 has a good safety.

Abstract
The process of erythroid differentiation is orchestrated at the molecular level by a complex network of transcription factors. Erythroid Krüppel-like factor (EKLF/KLF1) is a master erythroid gene regulator that directly regulates most aspects of terminal erythroid differentiation. However, the underlying regulatory mechanisms of EKLF protein stability are still largely unknown. In this study, we identified Vacuolar protein sorting 37 C (VPS37C), a core subunit of the Endosomal sorting complex required for transport-I (ESCRT-I) complex, as an essential regulator of EKLF stability. Our study showed that VPS37C interacts with EKLF and prevents K48-linked polyubiquitination of EKLF and proteasome-mediated EKLF degradation, thus enhancing EKLF protein stability and transcriptional activity. VPS37C overexpression in murine erythroleukemia (MEL) cells promotes hexamethylene bisacetamide (HMBA)-induced erythroid differentiation manifested by up-regulating erythroid-specific EKLF target genes and increasing benzidine-positive cells. In contrast, VPS37C knockdown inhibits HMBA-induced MEL cell erythroid differentiation. Particularly, the restoration of EKLF expression in VPS37C-knockdown MEL cells reverses erythroid-specific gene expression and hemoglobin production. Collectively, our study demonstrated VPS37C is a novel regulator of EKLF ubiquitination and degradation, which plays a positive role in erythroid differentiation of MEL cells by enhancing EKLF protein stability.

Abstract
Objective: To evaluate the efficacy of supraclavicular fasciocutaneous island flap (SIF) for repairing the defect of parotid or auricle regions after tumor resection. Methods: From February 2019 to June 2021, 12 patients (11 males and 1 female, aged 54-77 years old), of whom 4 with parotid adenoid cystic carcinoma and 8 with auricular basal cell carcinoma underwent reconstruction surgery for postoperative defects in the parotid gland area and auricular area with SIF in the Department of Otorhinolaryngology Head and Neck Surgery, the Second Xiangya Hospital of Central South University and their clinical data were retrospectively analyzed. Size of the SIF, time for harvesting SIF, neck lymph node dissection and postoperative complications were recorded. Results: The flap areas were (6-9) cm × (8-13) cm, and the harvesting time for SIF ranged from 40 to 80 min, averaging 51.7 min. The donor sites were directly closed. All patients underwent ipsilateral levels Ⅰ-Ⅲ neck dissection, with 4 cases undergoing additional level Ⅳ neck dissection and 2 cases undergoing level Ⅳ-Ⅴ neck dissection. Of the 12 SIF, 10 were completely survival and 2 had flap arterial crisis with partial flap necrosis, in addition, 1 had donor site wound dehiscence. With follow-up of 10-42 months, there were no tumor recurrences in 10 patients, 1 patient was lost to follow-up at 10 months postoperatively, and 1 patient experienced local tumor recurrence at 11 months after surgery and died 15 months later. Conclusion: SIF is an easily harvested flap with good skin features matching the skin in parotid and auricle regions and less damage to donor site, and this flap has no need for microvascular anastomosis technique. SIF is feasible and effective for repairing defects in parotid and auricle area.

Abstract
Agriculture produces food, fiber and biofuels for the world's growing population, however, agriculture can be a major contributor of nitrogen (N) losses including emissions of ammonia (NH3), nitrous oxide (N2O) and nitrate (NO3-) leaching and runoff. A Canadian Agricultural Nitrogen Budget for Reactive N (CANBNr) model was developed to estimate the soil N balance in 3487 soil landscape of Canada polygons from 1981 to 2016. The CANBNr model integrates NH3 emission from fertilizers, manure from housing, storage and field, as well as direct/indirect N2O emissions from fertilizers, manures, crop residues and soil organic matter. The NO3- leaching is estimated based on the residual soil N (RSN) at harvest and drainage derived with the DeNitrification-DeComposition (DNDC) model. From 1981 to 2016, the N input from fertilizer and N fixation increased at a greater rate than N removal in harvested crops in all provinces of Canada, resulting in an increase in the RSN and N losses. In 2016, the Prairie provinces had lower N losses (11.7 kg N ha-1) from N2O, NH3 and NO3- compared with 43.2 kg N ha-1 in central Canada, and 76.5 kg N ha-1 in Atlantic Canada. However, the Prairie provinces had 84.3% of the total Canadian farmland (74.3% of the total Canadian N input), while central Canada had 12.9% of Canadian farmland (21.7% of the total Canadian N input). In the Prairie provinces, the total N2O loss from fertilizer N ranged 4.4-8.6 Gg N whereas NH3 loss ranged from 17.1 to 44.6 Gg N and these values were influenced by both emission intensity and total land area. Total N2O losses from manure were highest in Alberta, Ontario and Quebec resulting in 4.8, 4.4, and 3.4 Gg N and NH3 losses from manure were also highest in these 3 provinces at 61.1, 45.2 and 40.4 Gg N, respectively. Nitrate leaching was impacted by drainage volumes, soil type and N inputs. In the non-growing season, NO3- leaching losses (36-yr average) were 63.3 Gg in Ontario and 57.5 Gg N in Quebec compared with 20.8 Gg N for Ontario and 35.5 Gg N for Quebec in the growing season. In contrast, the Prairie provinces showed higher NO3- leaching in the growing season (23.1-37.4 Gg N) than in the non-growing season (10.4-13.7 Gg N). In summary, total fertilizer N increased the most over the 36 years in the Prairies which resulted in increased RSN and N leaching losses that will require further intervention.

Abstract
Seasonal influenza, causes millions of deaths annually, posing a severe threat to human health. Currently available influenza vaccines are targeted only at specific strains or conserved epitopes; however, these vaccines are not completely efficacious because influenza viruses can undergo mutation during circulation, leading to antigenic mismatch between recommended strains and circulating strains and elusion from the immune system. Therefore, developing an influenza vaccine that is quick, effective, and broadly protective has become crucial, and the integral part of hemagglutinin (HA) remains an ideal target for vaccine development. This study developed a lipid nanoparticle-encapsulated nucleoside-modified mRNA vaccine (mRNA-LNPs) encoding a consensus full-length HA sequence (H1c) and evaluated its protective efficacy and immunogenicity through in vitro and in vivo assays. Following two intramuscular immunizations (2 µg, 10 µg, or 20 µg) at a 3-week interval in BALB/c mice, H1c-mRNA-LNP vaccine induced strong antibodies as shown in the hemagglutination-inhibition test and protective neutralizing antibodies against numerous heterologous H1N1 influenza viruses as shown in the microneutralization assay. Additionally, both Th1- and Th2-biased cellular immune responses were elicited, with the Th1-biased response being stronger. Two doses of the H1c-mRNA-LNP vaccine could neutralize a panel of heterologous H1N1 influenza viruses and could confer protection in mice. Taken together, these findings suggest that the H1c-mRNA-LNP vaccine encoding a consensus full-length HA is a feasible strategy for developing a cross-protective vaccine against a panel of heterologous H1N1 influenza viruses.

Abstract
This article reviews the relevant studies on the efficacy and safety of influenza, pneumococcal and COVID-19 vaccination among tumor patients worldwide in recent years. By combing and analyzing the retrieved literature, the results show that influenza and pneumococcal vaccination can significantly reduce the morbidity and hospitalization rate of infectious diseases in tumor patients, reduce the risk of cardiovascular events and death, and significantly improve survival prognosis. COVID-19 vaccination can also protect tumor patients, especially those who have completed full dose vaccination. Authoritative guidelines and consensuses worldwide all recommend that tumor patients receive influenza, pneumococcal and COVID-19 vaccines. We should carry out relevant researches, as well as take effective measures to strengthen patient education, so that tumor patients can fully experience the health protection brought by the vaccine to this specific group.

Abstract
The immunity of patients who recover from coronavirus disease 2019 (COVID-19) could be long lasting but persist at a lower level. Thus, recovered patients still need to be vaccinated to prevent reinfection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or its mutated variants. Here, we report that the inactivated COVID-19 vaccine can stimulate immunity in recovered patients to maintain high levels of anti-receptor-binding domain (RBD) and anti-nucleocapsid protein (NP) antibody titers within 9 months, and high neutralizing activity against the prototype, Delta, and Omicron strains was observed. Nevertheless, the antibody response decreased over time, and the Omicron variant exhibited more pronounced resistance to neutralization than the prototype and Delta strains. Moreover, the intensity of the SARS-CoV-2-specific CD4+ T cell response was also increased in recovered patients who received COVID-19 vaccines. Overall, the repeated antigen exposure provided by inactivated COVID-19 vaccination greatly boosted both the potency and breadth of the humoral and cellular immune responses against SARS-CoV-2, effectively protecting recovered individuals from reinfection by circulating SARS-CoV-2 and its variants.

Abstract
Objective: This study was performed to investigate the feasibility of preservation of internal branch of superior laryngeal nerve(ibSLN) during transoral endoscopic surgery for hypopharyngeal squamous cancer(HSCC) and the influence on patient's swallowing function after operation. Methods: From May 2020 to June 2021, the data of 29 HSCC patients who required for transoral endoscopic surgery in the Department of Otorhinolaryngology Head and Neck Surgery, the Second Xiangya Hospital of Central South University were prospectively included, and the included patients were divided into two groups randomly by lottery. According to whether ibSLN was actively dissected during operation, they were divided into ibSLN preservation group (n=15) and control group (n=14, without ibSLN preservation). Operation time, intraoperative hemorrhage, intraoperative neck dissection, postoperative radiotherapy, postoperative recurrence within 1 year, retention and swallowing function, the recovery of oral soft diet and the quality of life were compared between two groups. SPSS 25.0 software was used for statistical analysis. Results: The study included 29 eligible patients, including 25 males and 4 females.The age ranged from 42 to 67 (56.07±5.93) years. There were no significant differences(P>0.05) between 2 groups in the following data,including age(t=-0.56), gender(χ2=0.01), TNM stage(T stageχ2=0.29, N stage χ2=0.02), pathological diagnosis(χ2=0.03), preoperative swallowing function(χ2=0.00) and M. D. Anderson Dysphagia Inventory(MDADI) score(global t=0.55, emotional t=0.16, functional t=0.60, physical t=0.64), operation time(t=1.62) and intraoperative hemorrhage(t=-1.46), intraoperative neck dissection(χ2=0.01), postoperative radiotherapy(χ2=0.32), postoperative recurrence within 1 year(P>0.050). The swallowing function was evaluated by water swallowing test after operation. The swallowing function of ibSLN preservation group was better than control group, and the difference between two groups was statistically significant on the 1st (χ2=4.44, P=0.035), 5th (χ2=4.24, P=0.039) and 7th (χ2=4.55, P=0.033) day after operation. On the 14th day after operation, the MDADI scores of patients in the ibSLN preservation group were higher than those in the control group in global (t=2.45, P=0.021), functional (t=2.54, P=0.017) and physical (t=2.24, P=0.034) dimensions, except for emotional dimension (t=1.89, P=0.070). The median time of oral soft diet(U=23.00, P<0.001), normal oral diet(U=21.00, P<0.001) and the nasogastric tube removal time (U=18.50, P<0.001) in ibSLN preservation group was 2 days, 5 days and 6 days respectively, earlier than that in control group, which had statistically significant difference. Conclusion: Our results show that it is feasible to preserve the ibSLN during HSCC transoral endoscopic surgery, which can achieve rapid recovery of postoperative swallowing function.

Abstract
Herein, A non-invasive pathomics approach was developed to reveal the methylation status in patients with cervical squamous cell carcinoma and predict clinical outcomes and treatment response. Using the MethylMix algorithm, 14 methylation-driven genes were selected for further analysis. We confirmed that methylation-driven genes were differentially expressed in immune, stromal, and tumor cells. In addition, we constructed a methylation-driven model and explored the alterations in immunocyte infiltration between the different models. The methylation-driven subtypes identified in our investigation could effectively predict the clinical outcomes of cervical cancer. To further evaluate the level of methylation-driven patterns, we constructed a risk model with four genes. Significant correlations were observed between the score and immune response markers, including PD1 and CTLA4. Multiple immune infiltration algorithms evaluated the level of immunocyte infiltration between the high- and low-risk groups, while the components of anti-tumor immunocytes in the low-risk group were significantly increased. Subsequently, a total of 205 acquired whole-slide imaging (WSI) images were processed to capture image signatures, and the pathological algorithm was employed to construct an image prediction model based on the risk score classification. The model achieved an area under the curve (AUC) of 0.737 and 0.582 for the training and test datasets, respectively. Moreover, we conducted vitro assays for validation of hub risk gene. The proposed prediction model is a non-invasive method that combines pathomics features and genomic profiles and shows satisfactory performance in predicting patient survival and treatment response. More interdisciplinary fields combining medicine and electronics should be explored in the future.

Methods: Clinical features of 436 BL patients who were ≤18 years old and treated with the CNCL-B-NHL-2017 regimen from May 2017 to April 2021 were analyzed retrospectively. Clinical characteristics of patients at disease onset were analyzed and the therapeutic effects of patients with different clinical stages and risk groups were compared. Survival analysis was performed by Kaplan-Meier method, and Cox regression was used to identify the prognostic factors. Results: Among 436 patients, there were 368 (84.4%) males and 68 (15.6%) females, the age of disease onset was 6.0 (4.0, 9.0) years old. According to the St. Jude staging system, there were 4 patients (0.9%) with stage Ⅰ, 30 patients (6.9%) with stage Ⅱ, 217 patients (49.8%) with stage Ⅲ, and 185 patients (42.4%) with stage Ⅳ. All patients were stratified into following risk groups: group A (n=1, 0.2%), group B1 (n=46, 10.6%), group B2 (n=19, 4.4%), group C1 (n=285, 65.4%), group C2 (n=85, 19.5%). Sixty-three patients (14.4%) were treated with chemotherapy only and 373 patients (85.6%) were treated with chemotherapy combined with rituximab. Twenty-one patients (4.8%) suffered from progressive disease, 3 patients (0.7%) relapsed, and 13 patients (3.0%) died of treatment-related complications. The follow-up time of all patients was 24.0 (13.0, 35.0) months, the 2-year event free survival (EFS) rate of all patients was (90.9±1.4) %. The 2-year EFS rates of group A, B1, B2, C1 and C2 were 100.0%, 100.0%, (94.7±5.1) %, (90.7±1.7) % and (85.9±4.0) %, respectively. The 2-year EFS rates was higher in group A, B1, and B2 than those in group C1 (χ2=4.16, P=0.041) and group C2 (χ2=7.21, P=0.007). The 2-year EFS rates of the patients treated with chemotherapy alone and those treated with chemotherapy combined with rituximab were (79.3±5.1)% and (92.9±1.4)% (χ2=14.23, P<0.001) respectively. Multivariate analysis showed that stage Ⅳ (including leukemia stage), serum lactate dehydrogenase (LDH)>4-fold normal value, and with residual tumor in the mid-term evaluation were risk factors for poor prognosis (HR=1.38,1.23,8.52,95%CI 1.05-1.82,1.05-1.43,3.96-18.30). Conclusions: The CNCL-B-NHL-2017 regimen show significant effect in the treatment of pediatric BL. The combination of rituximab improve the efficacy further.

Abstract
Objective: To study the expression of methyltransferase-like protein 14 (METTL14) in epithelial ovarian cancer and its clinical significance, and to explore the effect of METTL14 expression on the proliferation, invasion and migration of ovarian cancer cells. Methods: Immunohistochemistry (IHC) was used to detect METTL14 expression in tumor tissue samples, and analyze the relationships among METTL14 expression, clinicopathological factors, and prognosis in ovarian cancer. Lentiviral vectors and small interfering RNA (siRNA) were used to up-regulate and down-regulate the METTL14 expression in ovarian cancer cell lines A2780 and SKOV3, respectively. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was used to detect the N6-methyladenosine (m6A) content in ovarian cancer cells. Cell counting kit-8 (CCK-8), wound healing assay, and transwell assay were used to examine the function of METTL14 expression in the cells. Results: (1) The IHC score of METTL14 protein was 6.2±3.7 in 20 samples of ovarian cancer tissues and 3.3±2.5 in 15 samples of normal ovarian tissues, and the difference was statistically significant (t=-2.64, P=0.012). Among the patients who suffered from ovarian cancer, there were 69 cases with high expression of METTL14 protein (IHC score≥6), accounting for 57.0% (69/121), and the cases with low expression of METTL14 protein (IHC score<6) accounting for 43.0% (52/121). Compared with the patients with low expression of METTL14, the patients with high expression of METTL14 had later stages, higher rates of lymph node metastasis, abdominal metastasis, and more ascite amount. The differences were statistically significant (all P<0.05). The overall survival rate was significantly lower in patients with high METTL14 expression than the low expression (P=0.009). (2) LC-MS/MS data showed that the relative expression of m6A in A2780 and SKOV3 cells in the lentivirus (LV)-METTL14 group were 0.213±0.024 and 0.181±0.018, which were significantly higher than those in the LV-normal control (NC) group (0.109±0.022 and 0.128±0.020; all P<0.05). While the relative expression of m6A in A2780 and SKOV3 cells in the si-METTL14 group were 0.063±0.012 and 0.069±0.015, which were significantly lower than the expression in si-NC group of 0.108±0.014 and 0.121±0.014 (all P<0.05). CCK-8 assay showed that the absorbance values were significantly lower in the si-METTL14 group compared with the si-NC group at 36, 48, 60 hours (all P<0.05); while were significantly increased in the LV-METTL14 group compared with the LV-NC group at 48, 60 hours (all P<0.01). Scratch wound assays showed that the migration rate of the si-METTL14 group was lower than those of the si-NC group, while the LV-METTL14 group were higher than the LV-NC group by 24 hours, the differences were statistically significant (all P<0.01). Cell migration and invasion were detected by transwell migration and invasion assays. After cultivated for 24 hours, the invasion cell number and the migration cell number in the si-METTL14 group were less than those in the si-NC group. While the invasion cell number and the migration cell number in the LV-METTL14 group were more than those in the LV-NC group, respectively. The differences were statistically significant (all P<0.01). Conclusion: Patients with high METTL14 expression have a worse prognosis in ovarian cancer, which may increase the m6A modification of ovarian cancer cells and promote cells proliferation, invasion and migration.

Abstract
Drying plays a significant role in Ginkgo biloba seed's (GBS) processing, and the previous research showed drying affected the product quality. A combined hurdle drying technology (integrated non-thermal pretreatment and drying) could be applied on GBS to achieve better product quality. Osmotic (OS), osmo-vacuum (OS + V), sonication (US), and osmosonication (OS + US) pretreatment followed by infrared drying was performed on GBS, and the product qualities (texture, color, enzyme inactivation, water activity, and microstructure), physicochemical properties (titrable acidity, reducing sugar, soluble solids, total sugar, free amino acid, and ascorbic acid), and organoleptic qualities were evaluated. Results showed pretreatment had various effects on physicochemical and product quality, and was confirmed by principal component analysis (PCA). The sensory scores, acceptability index combined with Pearson's correlation, and PCA showed that different pretreatments influenced the likeness and acceptability, and color, taste, and odor were the key determinants and strongly associated with the consumers' preferences. The untreated GBS (no pretreatment before drying) had a higher color change and lower enzyme inactivation. Pretreatment increased texture preservation after thermal processing, although it had a negative effect on soluble solids, reducing sugar and total sugar content. While the US improved the texture, it resulted in shrinkage (from the microstructure) and total sugar degradation. Among the various hurdle technologies, osmosonication (OS + US, followed by infrared drying) had the highest sensory attributes, free amino acid, slight structure deformation, and lowest water activity. The present study showed that osmosonication is a promising hurdle technology for GBS because it provides better quality attributes. PRACTICAL APPLICATION: Previous research showed that Ginkgo biloba seed (GBS) drying has an impact on product quality, which will ultimately determine GBS acceptance. This research was set out to envisage and advance current dryer design by merging the sequential operations (integrated non-thermal pretreatment and drying), also known as hurdle drying technology on GBS, to achieve better process efficiency, product quality, and make GBS's drying process more sustainable. The various pretreatments improved ginkgo seed's product qualities compared to the control (no pretreatment prior to drying). Osmosonication is a promising hurdle technology for GBS processing.

Abstract
Vaccination is the most effective measure to prevent influenza. However, due to the existence of antigen drift and/or antigen shift of influenza virus, the vaccine strains often do not match the epidemic strains, so that the protection provided by influenza vaccine is still limited. With the rapid development of new vaccine technology, a kind of influenza vaccine with extensive protection or universal has attracted great attention. It can effectively induce humoral and cellular immunity against the conserved epitopes of influenza virus, provide good protection against various types/subtypes of influenza virus, and has a rapid production platform, which is the ideal goal for the development of a new generation of universal influenza vaccine. This article reviews the latest research progress of influenza universal vaccine.

Abstract
This study evaluated the mass transfer, drying, and rehydration kinetics (drying and rehydration curve, moisture diffusivity [Deff ]), energy consumption (specific energy consumption [SEC], moisture extraction rate (MER), and specific moisture extraction rate [SMER]), and mathematical modeling of infrared dried Ginkgo biloba seed (GBS) using the various nonthermal pretreatments namely: osmotic (OS), osmovacuum (V + OS), ultrasound (US, ginkgo seed immersed in a distilled water with US), and osmosonication (US + OS, ginkgo seeds immersed in an OS solution with US). Results showed that various pretreatments affected mass transfer, drying, and rehydration characteristics, and energy consumption, which was confirmed by principal component analysis. In terms of mass transfer, US pretreatment recorded the highest weight loss while the osmosonication pretreatment registered the highest solid gain. The entire drying process occurred in the falling-rate period. The Deff values were within the normal range of agroproducts (10-11 to 10-8 m2 /s). The modified Page-I and Weibull model best fitted the drying and rehydration kinetics, respectively, with the coefficient of determination (R2 ) > 0.991, root mean square error, residual sum of squares, and reduced chi-square closer to zero, compared with the other models. The untreated GBS (control) had the lowest energy efficiency (lowest SMER and MER) and the highest SEC than the pretreated GBS. Among the various pretreatments, the US pretreatment of GBS was superior, with the highest Deff , MER, SMER, and drying rate, and lowest drying time and SEC. Based on the findings, sequential US pretreatment and infrared drying is a feasible drying technique for GBS that could be used commercially. PRACTICAL APPLICATION: Ginkgo tree cultivation in China has exceeded market needs with 60,000 tons per annum of GBS produced. Hence, there is a compelling need to explore new chances to use GBS availability irrespective of the seasonality and address the problem where GBS utilization is limited to the early phases of home-cooked dishes. Although drying increases the shelf life of ginkgo seeds, there is a higher operation cost. Thus, pretreatment can reduce energy consumption and augment the product quality is ideal. This research reported the impact of nonthermal pretreatments on ginkgo seeds' mass transfer, drying, and rehydration characteristics. The present results will provide a comprehensive understanding of the engineering application of ginkgo seed pretreatment, allowing for the best technique to be selected.

Abstract
BACKGROUND Although SARS-CoV-2 infection often causes milder symptoms in children and adolescents, young people might still play a key part in SARS-CoV-2 transmission. An efficacious vaccine for children and adolescents could therefore assist pandemic control. For further evaluation of the inactivated COVID-19 vaccine candidate BBIBP-CorV, we assessed the safety and immunogenicity of BBIBP-CorV in participants aged 3-17 years. METHODS A randomised, double-blind, controlled, phase 1/2 trial was done at Shangqiu City Liangyuan District Center for Disease Control and Prevention in Henan, China. In phases 1 and 2, healthy participants were stratified according to age (3-5 years, 6-12 years, or 13-17 years) and dose group. Individuals with a history of SARS-CoV-2 or SARS-CoV infection were excluded. All participants were randomly assigned, using stratified block randomisation (block size eight), to receive three doses of 2 μg, 4 μg, or 8 μg of vaccine or control (1:1:1:1) 28 days apart. The primary outcome, safety, was analysed in the safety set, which consisted of participants who had received at least one vaccination after being randomly assigned, and had any safety evaluation information. The secondary outcomes were geometric meant titre (GMT) of the neutralising antibody against infectious SARS-CoV-2 and were analysed based on the full analysis set. This study is registered with www.chictr.org.cn, ChiCTR2000032459, and is ongoing. FINDINGS Between Aug 14, 2020, and Sept 24, 2020, 445 participants were screened, and 288 eligible participants were randomly assigned to vaccine (n=216, 24 for each dose level [2/4/8 μg] in each of three age cohorts [3-5, 6-12, and 13-17 years]) or control (n=72, 24 for each age cohort [3-5, 6-12, and 13-17 years]) in phase 1. In phase 2, 810 participants were screened and 720 eligible participants were randomly assigned and allocated to vaccine (n=540, 60 for each dose level [2/4/8 μg] in each of three age cohorts [3-5, 6-12, and 13-17 years]) or control (n=180, 60 for each age cohort [3-5, 6-12, and 13-17 years]). The most common injection site adverse reaction was pain (ten [4%] 251 participants in all vaccination groups of the 3-5 years cohort; 23 [9·1%] of 252 participants in all vaccination groups and one [1·2%] of 84 in the control group of the 6-12 years cohort; 20 [7·9%] of 252 participants in all vaccination groups of the 13-17 years cohort). The most common systematic adverse reaction was fever (32 [12·7%] of 251 participants in all vaccination groups and six [7·1%] of 84 participants in the control group of the 3-5 years cohort; 13 [5·2%] of 252 participants in the vaccination groups and one [1·2%] of 84 in the control group of the 6-12 years cohort; 26 [10·3%] of 252 participants in all vaccination groups and eight [9·5%] of 84 in the control group of the 13-17 years cohort). Adverse reactions were mostly mild to moderate in severity. The neutralising antibody GMT against the SARS-CoV-2 virus ranged from 105·3 to 180·2 in the 3-5 years cohort, 84·1 to 168·6 in the 6-12 years cohort, and 88·0 to 155·7 in the 13-17 years cohort on day 28 after the second vaccination; and ranged from 143·5 to 224·4 in the 3-5 years cohort, 127 to 184·8 in the 6-12 years cohort, and 150·7 to 199 in the 13-17 years cohort on day 28 after the third vaccination. INTERPRETATION The inactivated COVID-19 vaccine BBIBP-CorV is safe and well tolerated at all tested dose levels in participants aged 3-17 years. BBIBP-CorV also elicited robust humoral responses against SARS-CoV-2 infection after two doses. Our findings support the use of a 4 μg dose and two-shot regimen BBIBP-CorV in phase 3 trials in the population younger than 18 years to further ascertain its safety and protection efficacy against COVID-19.

Abstract
The compound [3-(1H-benzimidazol-2-methylene)-5-(2-methylphenylaminosulfo)-2-indolone], known as Indo5, is a novel selective inhibitor of c-Met and Trks, and it is a promising anticancer candidate against hepatocellular carcinoma (HCC). Assessing the pharmacokinetic properties, tissue distribution, and toxicity of Indo5 is critical for its medicinal evaluation. A series of sensitive and specific liquid chromatography-tandem mass spectrometry methods were developed and validated to determine the concentration of Indo5 in rat plasma and tissue homogenates. These methods were then applied to investigate the pharmacokinetics and tissue distribution of Indo5 in rats. After intravenous injection of Indo5, the maximum concentration (Cmax) and the time at which Cmax was reached (Tmax) were 1,565.3 ± 286.2 ng/ml and 1 min, respectively. After oral administration, Cmax and Tmax were 54.7 ± 10.4 ng/ml and 2.0 ± 0.48 h, respectively. We calculated the absolute oral bioavailability of Indo5 in rats to be 1.59%. Following intravenous injection, the concentrations of Indo5 in various tissues showed the following order: liver > kidney ≈ heart > lung ≈ large intestine ≈ small intestine ≈ stomach > spleen > brain ≈ testes; hence, Indo5 distributed highest in the liver and could not cross the blood–brain or blood–testes barriers. Continuous injection of Indo5 for 21 days did not lead to liver injury, considering unchanged ALT and AST levels, normal histological architecture of the liver, and normal number and frequencies of immune cells in the liver, indicating a very low toxicity of Indo5 in vivo. Collectively, our findings provide a comprehensive understanding of the biological actions of Indo5 in vivo and further support its development as an antitumor treatment for HCC patients.

Abstract
One of the best ways to control COVID-19 is vaccination. Among the various SARS-CoV-2 vaccines, inactivated virus vaccines have been widely applied in China and many other countries. To understand the underlying protective mechanism of these vaccines, it is necessary to systematically analyze the humoral responses that are triggered. By utilizing a SARS-CoV-2 microarray with 21 proteins and 197 peptides that fully cover the spike protein, antibody response profiles of 59 serum samples collected from 32 volunteers immunized with the inactivated virus vaccine BBIBP-CorV were generated. For this set of samples, the microarray results correlated with the neutralization titers of the authentic virus, and two peptides (S1-5 and S2-22) were identified as potential biomarkers for assessing the effectiveness of vaccination. Moreover, by comparing immunized volunteers to convalescent and hospitalized COVID-19 patients, the N protein, NSP7, and S2-78 were identified as potential biomarkers for differentiating COVID-19 patients from individuals vaccinated with the inactivated SARS-CoV-2 vaccine. The comprehensive profile of humoral responses against the inactivated SARS-CoV-2 vaccine will facilitate a deeper understanding of the vaccine and provide potential biomarkers for inactivated virus vaccine-related applications.

Abstract
Objective: To estimate the healthy life expectancy (HALE) of registered residents in Jing'an District, Shanghai City. Methods: From June to August in 2017, 14 districts (towns) were selected as the research sites, and 4 159 registered residents were selected as the subjects. The health status data of subjects were collected by using the self-rated health scale, and the health rate of subjects was obtained by using the CHOPIT model. The health rate of residents under 18 years old was replaced by the parameters of 18-year-old group, and Sullivan method was used to calculate the HALE of registered residents in Jing'an District, Shanghai City. Results: The age of 4 159 subjects was (56.46±15.19) years old, ranging from 18 to 98 years old. There were 1 768 males (42.5%). The overall health rate of subjects was 74.96%, of which the health rates of male and female were 76.87% and 72.45% respectively. With the increase of age, the health rate decreased (Z=265.51, P<0.001), and the health rate of male was higher than that of female (χ²=2 154.54, P<0.001). The HALE of the 0-year-old group was 64.29 years old, in which the male and female were 66.25 and 63.57 years old respectively. Among the 18-year-old group, the HALE was 48.18 years old, with 49.07 years old for male and 47.46 years old for female. The HALE of male was higher than that of female in all age groups. With the increase of age, the HALE decreased gradually. Conclusion: There are significant sex and age differences in HALE in Jing'an District, Shanghai City. The health issue of female and older people should be given more attention.

Abstract
We investigate localization properties of two-coupled uniform chains (ladder) with quasiperiodic modulation on interchain coupling strength. We demonstrate that this ladder is equivalent to two Aubry-André chains when two legs are symmetric. Analytical and numerical results indicate the appearance of mobility edges in asymmetric ladder systems. We propose an easy-to-engineer quasiperiodic Moiré superlattice ladder system comprising two-coupled uniform chains. An irrational lattice constant difference results in a quasiperiodic structure. Numerical simulations indicate that such a system supports the existence of mobility edges. Furthermore, we demonstrate that the mobility edges can be detected through a dynamical method, that is based on the measurement of survival probability in the presence of a single imaginary negative potential. The results provide insights into localization transitions and mobility edges in experiments.

Abstract
Background Rotavirus infections, prevalent in human populations, are caused mostly by group A viruses. Immunization against rotaviruses in infancy is currently the most effective and economical strategy to prevent rotavirus infection. This study evaluated the safety of a novel hexavalent rotavirus vaccine and analyzed its dose and immunogenicity.Methods This randomized, double-blinded, placebo-controlled phase I clinical trial enrolled healthy adults, toddlers, and infants in Zhengding County, Hebei Province, northern China. 40 adults and 40 children were assigned in a 2:1:1 ratio to receive one vaccine dose, placebo 1, and placebo 2, respectively. 120 6-12 week old infants were assigned equivalently into 3 groups. The infants in each group were assigned in a 2:1:1 ratio to receive three doses of vaccine, placebo 1, and placebo 2, at a 28-day interval. Adverse events (AEs) until 28 days after each dose and serious adverse events (SAEs) until 6 months after the third dose were reported. Virus shedding until 14 days after each dose in infants was tested. Geometric mean concentrations (GMCs) and seroconversion rates were measured for anti-rotavirus IgA by using an enzyme-linked immunosorbent assay (ELISA).Results The solicited and unsolicited AE frequencies and laboratory indexes were similar among the treatment groups. No vaccine-related SAEs were reported. The average percentage of rotavirus vaccine shedding in the infant vaccine groups was 5.00%. The post-3rd dose anti-rotavirus IgA antibody geometric mean concentrations (GMC) and seroconversion rate were higher in the vaccine groups than in the placebo groups.Conclusions The novel oral hexavalent rotavirus vaccine was generally well-tolerated in all adults, toddlers and infants, and the vaccine was immunogenic in infants.

Abstract
BACKGROUND Ginkgo biloba seeds are used as a functional food across Asia. However, the presence of toxic compounds has limited their application. In this study, freeze drying, infrared drying, hot-air drying and pulsed-vacuum drying were used to dry G. biloba seeds. A comprehensive analysis was performed on their product quality, antioxidant activities, bioactive and toxic components. RESULTS Results showed that the drying methods had a significant influence on product quality with freeze drying being superior due to the minimal microstructural damage, followed by infrared drying and pulsed-vacuum drying. Infrared-dried product possessed the strongest antioxidant activities and higher bioactive compound content than hot-air-dried and pulsed-vacuum-dried product. Toxic compounds in fresh G. biloba seeds (ginkgotoxin, ginkgolic acid and cyanide) were reduced markedly by drying. Ginkgotoxin was reduced fourfold, and the contents of acrylamide, ginkgolic acid and cyanide in dried G. biloba seeds were reduced to the scope of safety. Amongst the four drying methods, infrared drying had the shortest drying time, and its product showed higher quality and bioactive compound content, and stronger antioxidant activities. CONCLUSIONS These findings will offer salient information for selecting a drying method during the processing of ginkgo seeds. Infrared drying could be considered as a multiple-effect drying method in the processing of ginkgo seeds. © 2020 Society of Chemical Industry.

Abstract
Pharmacologically inhibiting nucleotide-binding domain and leucine-rich repeat-containing (NLR) family, pyrin domain-containing protein 3 (NLRP3) inflammasome activation results in potent therapeutic effects in a wide variety of preclinical inflammatory disease models. NLRP3 deubiquitination is essential for efficient NLRP3 inflammasome activity, but it remains unclear whether this process can be harnessed for therapeutic benefit. Here, we show that thiolutin (THL), an inhibitor of the JAB1/MPN/Mov34 (JAMM) domain-containing metalloprotease, blocks NLRP3 inflammasome activation by canonical, noncanonical, alternative, and transcription-independent pathways at nanomolar concentrations. In addition, THL potently inhibited the activation of multiple NLRP3 mutants linked with cryopyrin-associated periodic syndromes (CAPS). Treatment with THL alleviated NLRP3-related diseases in mouse models of lipopolysaccharide-induced sepsis, monosodium urate-induced peritonitis, experimental autoimmune encephalomyelitis, CAPS, and methionine-choline-deficient diet-induced nonalcoholic fatty liver disease. Mechanistic studies revealed that THL inhibits the BRCC3-containing isopeptidase complex (BRISC)-mediated NLRP3 deubiquitination and activation. In addition, we show that holomycin, a natural methyl derivative of THL, displays an even higher inhibitory activity against NLRP3 inflammasome than THL. Our study validates that posttranslational modification of NLRP3 can be pharmacologically targeted to prevent or treat NLRP3-associated inflammatory diseases. Future clinical development of derivatives of THL may provide new therapies for NLRP3-related diseases.

Abstract
The Laoguan River is the tributary of Danjiangkou Reservoir located nearest to the water diversion outlet, and water quality here directly affects the safety of the diverted water. To explore the community composition and functional change of bacterioplankton in the Laoguan River before and after the flood season, four representative sites were sampled in the main stream before (May) and after (October) the 2018 and 2019 flood seasons. Water quality was assessed and high-throughput sequencing of bacterioplankton was performed. Yanghe (YH) was slightly disturbed, Xixiabei (XX) was moderately disturbed, Dangziling (DZL) was heavily disturbed, and Zhangying (ZY) was moderately disturbed. In total, 599 genera from 40 phyla were collected. The diversity of bacterioplankton before the flood season was higher than afterwards, and moderate levels of disturbance increased the Shannon-Wiener diversity index. LEfSe analysis indicated that significant differences existed in some dominant phyla; Armatimonadete in Yanghe, Epsilonbacteraeota and Firmicutes in Xixiabei, and Cyanophyta in Dangziling dominated before flood season, while significant differences only occurred in Firmicutes and Cyanophyta in Dangziling after the flood season. The PCoA of the bacterioplankton community showed that the sampling points were distinct before and after the flood season, and that differences among samples were greater before the flood season. The RDA and CCA indicated that total nitrogen and ammonia nitrogen were the main environmental factors causing declines in bacterioplankton diversity. PICRUSt showed a total of ten dominant categories of COG function genes. A total of 30 KO function genes related to nitrogen metabolism group also different between the two periods, with greater differences before flood season. The genes cynt and can in Yanghe were significant different from the other three sampling points before the flood season. Overall, nitrogen and phosphorus were the main factors regulating the bacterioplankton community structure and eutrophication in the Laoguan River. Changes in nitrogen inputs will result in changes in microbial nitrogen metabolic function in different regions of the river.

Abstract
BACKGROUND Toll-like receptor 5 (TLR5)-mediated pathways play critical roles in regulating the hepatic immune response and show hepatoprotective effects in mouse models of hepatic diseases. However, the role of TLR5 in experimental models of liver regeneration has not been reported. This study aimed to investigate the role of TLR5 in partial hepatectomy (PHx)-induced liver regeneration. METHODS We performed 2/3 PHx in wild-type (WT) mice, TLR5 knockout mice, or TLR5 agonist CBLB502 treated mice, as a model of liver regeneration. Bacterial flagellin content was measured with ELISA, and hepatic TLR5 expression was determined with quantitative PCR analyses and flow cytometry. To study the effects of TLR5 on hepatocyte proliferation, we analyzed bromodeoxyuridine (BrdU) incorporation and proliferating cell nuclear antigen (PCNA) expression with immunohistochemistry (IHC) staining. The effects of TLR5 during the priming phase of liver regeneration were examined with quantitative PCR analyses of immediate early gene mRNA levels, and with Western blotting analysis of hepatic NF-κB and STAT3 activation. Cytokine and growth factor production after PHx were detected with real-time PCR and cytometric bead array (CBA) assays. Oil Red O staining and hepatic lipid concentrations were analyzed to examine the effect of TLR5 on hepatic lipid accumulation after PHx. RESULTS The bacterial flagellin content in the serum and liver increased, and the hepatic TLR5 expression was significantly up-regulated in WT mice after PHx. TLR5-deficient mice exhibited diminished numbers of BrdU- and PCNA-positive cells, suppressed immediate early gene expression, and decreased cytokine and growth factor production. Moreover, PHx-induced hepatic NF-κB and STAT3 activation was inhibited in Tlr5-/- mice, as compared with WT mice. Consistently, the administration of CBLB502 significantly promoted PHx-mediated hepatocyte proliferation, which was correlated with enhanced production of proinflammatory cytokines and the recruitment of macrophages and neutrophils in the liver. Furthermore, Tlr5-/- mice displayed significantly lower hepatic lipid concentrations and smaller Oil Red O positive areas than those in control mice after PHx. CONCLUSION We reveal that TLR5 activation contributes to the initial events of liver regeneration after PHx. Our findings demonstrate that TLR5 signaling positively regulates liver regeneration and suggest the potential of TLR5 agonist to promote liver regeneration.

Abstract
The ongoing COVID-19 pandemic is causing huge impact on health, life, and global economy, which is characterized by rapid spreading of SARS-CoV-2, high number of confirmed cases and a fatality/case rate worldwide reported by WHO. The most effective intervention measure will be to develop safe and effective vaccines to protect the population from the disease and limit the spread of the virus. An inactivated, whole virus vaccine candidate of SARS-CoV-2 has been developed by Wuhan Institute of Biological Products and Wuhan Institute of Virology. The low toxicity, immunogenicity, and immune persistence were investigated in preclinical studies using seven different species of animals. The results showed that the vaccine candidate was well tolerated and stimulated high levels of specific IgG and neutralizing antibodies. Low or no toxicity in three species of animals was also demonstrated in preclinical study of the vaccine candidate. Biochemical analysis of structural proteins and purity analysis were performed. The inactivated, whole virion vaccine was characterized with safe double-inactivation, no use of DNases and high purity. Dosages, boosting times, adjuvants, and immunization schedules were shown to be important for stimulating a strong humoral immune response in animals tested. Preliminary observation in ongoing phase I and II clinical trials of the vaccine candidate in Wuzhi County, Henan Province, showed that the vaccine is well tolerant. The results were characterized by very low proportion and low degree of side effects, high levels of neutralizing antibodies, and seroconversion. These results consistent with the results obtained from preclinical data on the safety.

Abstract
Neurological diseases such as stroke, Alzheimer’s disease, Parkinson’s disease, and Huntington’s disease are among the intractable diseases for which appropriate drugs and treatments are lacking. Proteolysis targeting chimera (PROTAC) technology is a novel strategy to solve this problem. PROTAC technology uses the ubiquitin-protease system to eliminate mutated, denatured, and harmful proteins in cells. It can be reused, and utilizes the protein destruction mechanism of the cells, thus making up for the deficiencies of traditional protein degradation methods. It can effectively target and degrade proteins, including proteins that are difficult to identify and bind. Therefore, it has extremely important implications for drug development and the treatment of neurological diseases. At present, the targeted degradation of mutant BTK, mHTT, Tau, EGFR, and other proteins using PROTAC technology is gaining attention. It is expected that corresponding treatment of nervous system diseases can be achieved. This review first focuses on the recent developments in PROTAC technology in terms of protein degradation, drug production, and treatment of central nervous system diseases, and then discusses its limitations. This review will provide a brief overview of the recent application of PROTAC technology in the treatment of central nervous system diseases.

Abstract
In the face of COVID-19 pandemic caused by the newly emerged SARS-CoV-2, an inactivated, Vero cell-based, whole virion vaccine candidate has been developed and entered into phase III clinical trials within six months. Biochemical and immunogenic characterization of structural proteins and their post-translational modifications in virions, the end-products of the vaccine candidate, would be essential for the quality control and process development of vaccine products and for studying the immunogenicity and pathogenesis of SARS-CoV-2. By using a panel of rabbit antisera against virions and five structural proteins together with a convalescent serum, the spike (S) glycoprotein was shown to be N-linked glycosylated, PNGase F-sensitive, endoglycosidase H-resistant and cleaved by Furin-like proteases into S1 and S2 subunits. The full-length S and S1/S2 subunits could form homodimers/trimers. The membrane (M) protein was partially N-linked glycosylated; the accessory protein 3a existed in three different forms, indicative of cleavage and dimerization. Furthermore, analysis of the antigenicity of these proteins and their post-translationally modified forms demonstrated that S protein induced the strongest antibody response in both convalescent and immunized animal sera. Interestingly, immunization with the inactivated vaccine did not elicit antibody response against the S2 subunit, whereas strong antibody response against both S1 and S2 subunits was detected in the convalescent serum. Moreover, vaccination stimulated stronger antibody response against S multimers than did the natural infection. This study revealed that the native S glycoprotein stimulated neutralizing antibodies, while bacterially-expressed S fragments did not. The study on S modifications would facilitate design of S-based anti-SARS-CoV-2 vaccines.

Abstract
Objective: To study the risk of malnutrition and related factors of cancer patients in community of Shanghai. Methods: From October 2018 to January 2019, four communities, Pengpu New Village Street, Pengpu Town, Jiangning Road Street, and Caojiadu Street, from 14 communities in Jing 'an District, Shanghai City, were selected by using a random cluster sampling method based on the Shanghai Cancer Registration and reporting system. All cases of malignant tumors and benign tumors of the central nervous system were included. A total of 4 396 questionnaires were distributed. After the exclusion of 9 invalid questionnaires, 3 310 valid questionnaires were included with a rate of 99.73%. A self-designed questionnaire was used to collect data including basic demographic characteristics, history of malignant, physical and psychological pain, nutritional demands and cognitive status. Malnutrition Universal Screening Tools (MUST) was used to analyze the nutritional risk of cancer patients in the community. Multivariate logistic regression model was applied to analyze potential factors. Results: Among the 3 310 cancer patients who completed the survey, the average age of study participants was (64.05±13.02), and 1 467 cases (44.32%) were males. The incidence rate of nutritional risk was 12.84% (425/3 310). The result of logistic regression analysis showed that compared with male, other cancer patients and no physical pain, the risk factors of the occurrence of nutritional included: female (OR=1.53,95%CI:1.23-1.92), head and neck malignant tumors (OR=1.42,95%CI:1.07-1.90), bronchus/lung malignant tumors (OR=1.93,95%CI:1.43-2.61), liver, biliary/pancreatic malignant tumors (OR=2.11,95%CI:1.21-3.65) and upper gastrointestinal malignant tumors (OR=6.04,95%CI:4.31-8.46), patients with physical pain (OR=1.39,95%CI:1.02-1.89). Conclusion: Nutritional risk of cancer patients is higher in community of Shanghai. Gender, location of tumors and physical pain are associated with the occurrence of nutritional risk.

Abstract
BRCA1/BRCA2-containing complex subunit 3 (BRCC3) is a lysine 63-specific deubiquitinase involved in multiple biological processes, such as DNA repair and immune responses. However, the regulation mechanism for BRCC3 protein stability is still unknown. Here, we demonstrate that BRCC3 is mainly degraded through the ubiquitin-proteasome pathway. The HECT-type E3 ubiquitin ligase WWP2 modulates BRCC3 ubiquitination and degradation. ABRO1, a subunit of the BRCC36 isopeptidase complex (BRISC), competes with WWP2 to bind to BRCC3, thereby preventing WWP2-mediated BRCC3 ubiquitination and enhancing BRCC3 stability. Functionally, we show that lentivirus-mediated overexpression of WWP2 in murine macrophages inhibits NLRP3 inflammasome activation by decreasing BRCC3 protein level. This study provides the first insights into the regulation of BRCC3 stability and expands our knowledge about the physiological function of WWP2.

Abstract
Objective: To observe the analgesic effect, complication and patient satisfaction of Acute Pain Service (APS) after thoracic surgery. Methods: The clinical data were collected from 264 patients who underwent different thoracic surgery from January 2017 until December 2019 retrospectively. They were divided into thoracotomy group (group O) and thoracoscopy surgery group (group T). There were 90 cases in group O and 174 cases in group T. According to the use of APS, the group O is divided into the no-APS group (group O1) and the APS group (group O2), the group T is divided into the no-APS group (group T1) and the APS group (group T2). The effect of postoperative analgesia, the incidence of nausea and vomiting and the satisfaction of patients were compared between group O1 and group O2, group T1 and group T2, respectively. Results: In the resting state, the Numeric Rating Scales (NRS) scores of the group O2 at 0 h (0.92±0.50 vs 1.59±0.62), 4 h (0.92±0.50 vs 2.06±1.03), 8 h (0.92±0.50 vs 2.18±1.13), 12 h (0.92±0.50 vs 2.47±1.42), 24 h (1.00±0.71 vs 2.53±1.42), and 48 h (1.00±0.71 vs 2.35±1.80) after leaving the Anesthesia Recovery Room (PACU) were significantly lower than those of the group O1 (all P<0.05), and in the active state, the NRS scores of the group O2 at 0 h (P=0.023), 4 h (P=0.001), 8 h (P=0.000), 12 h (P=0.001), 24 h (P=0.000), 48 h (P=0.000), and 72 h (P=0.019) after leaving the PACU were significantly lower than those of the group O1 (all P<0.05). In the resting state, the NRS scores of the group T2 at 4 h (P=0.029), 8 h (P=0.008), 12 h (P=0.006), and 24 h (P=0.013) after leaving the PACU were significantly lower than those of the group T1 (all P<0.05). In the active state, the NRS scores of the group T2 at 4 h (P=0.019), 8 h (P=0.000), 12 h (P=0.001), 24 h (P=0.002), and 48 h (P=0.002) after leaving the PACU were significantly lower than those of the group T1 (all P<0.05). Conclusion: APS can significantly reduce the NRS scores after thoracotomy and thoracoscopic surgery compared to ordinary analgesia model.

Abstract
The nucleotide-binding domain and leucine-rich repeat-containing family pyrin domain containing 3 (NLRP3) inflammasome is involved in various acute and chronic liver diseases, however, it is not clear whether NLRP3 contributes to d-Galactosamine (D-GalN) plus lipopolysaccharide (LPS)-induced acute liver failure (ALF). This study aims to investigate the role of NLRP3 inflammasome in D-GalN/LPS-induced fatal hepatitis. We found that Nlrp3-/- and WT mice showed similar mortality against a lethal dose of D-GalN/LPS treatment. Serum ALT and AST levels, as well as liver necrosis area and hepatocyte apoptosis, were not significantly different between Nlrp3-/- and WT mice at 6 h after D-GalN/LPS injection. Moreover, the numbers of intrahepatic F4/80+ cells and Ly6G+ cells were comparable in two genotype mice following D-GalN/LPS treatment. Besides, Nlrp3-/- mice had reduced IL-1β levels but similar TNF-α, IL-6, and MCP-1 levels compared with WT mice upon D-GalN/LPS administration. Our findings revealed that NLRP3 ablation does not protect mice from D-GalN/LPS-induced fatal hepatitis and has a marginal effect on intrahepatic inflammatory response upon D-GalN/LPS treatment. This suggests that NLRP3 inflammasome does not appear to be a major contributor to D-GalN/LPS-induced ALF.

Abstract
OBJECTIVE To investigate the relationship between spine-pelvic sagittal parameters and clinical efficacy before and after oblique lumbar interbody fusion(OLIF). METHODS A retrospective analysis of clinical data of 65 patients with lumbar degenerative diseases treated with OLIF were performed from July 2017 to July 2018. There were 26 males and 39 females aged from 33 to 79 years old with an average of (62.72±10.23) years old. Oswestry Disability Index (ODI) and visual analogue scale (VAS) before and at the latest follow up were evaluated. Disc height (DH) and spine- pelvic sagittal parameters of the surgical segment were measured before and at the latest follow- up, including pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS) and lumbar lordosis (LL). According to the difference of PI-LL, it was judged whether PI and LL match and the patients were grouped, PI-LL ranged from -9° to 9° was set as matching group, and PI-LL less than -9° or larger than 9° was set as mismatching group. The spine-pelvic sagittal parameters were analyzed before and at the latest follow-up of OLIF in patients with lumbar degenerative diseases, and the correlation between changes and clinical efficacy was compared. RESULTS All patients were followed up from 8 to 20 months with an average of (14.20±3.68) months. Operation time was (91.54±25.97) min, intraoperative blood loss was (48.15±10.14) ml, and the hospitalization time ranged from 6 to 19 days with an average of (9.28± 2.50) days. Totally 84 surgical levels, 46 patients were single segment and 19 patients were double segments. VAS and ODI score were improved from (4.88±0.99) point, (67.60±13.73) % preoperatively to (2.85±1.30) points, (30.57±6.48) % at the latest follow-up. There were significant differences in VAS and ODI scores between before and at the latest follow-up. The sagittal parameters of LL, PT, SS, PI, PI -LL and the surgical level DH were (42.80 ±16.35)° , (23.22 ±10.91)° , (26.95 ± 13.30)°, (50.22±14.51)°, (7.53±16.13) °, (0.91±0.29) cm preoperatively and improved to the latest follow-up (49.95± 12.82) °, (17.94±9.24) °, (33.71±12.66) °, (51.65±10.26) °, (1.68±17.00) °, (1.20±0.40) cm;there were statistical differences in LL, PT, SS, PI-LL, DH before operation and at the latest follow up, while no difference in PI. LL of preoperative PI-LL in matched group was (48.76±11.09)° , and (38.00±18.37)° in PI-LL mismatch group, there was difference between two groups. There were no differences in VAS, ODI, PT, SS, PI and DH between two groups. At the latest follow-up, ODI between PI-LL matched group and PI-LL mismatched group were (29.40±5.93)% and (32.86±7.02)% respectively, and had difference in ODI between two groups;while there were no significant differences in VAS, LL, PT, SS, PI, and DH. Pearson correlation analysis showed preoperative PT-LL was positively correlated with VAS;PT was positively correlated with ODI at the latest follow-up. CONCLUSION OLIF has a good surgical effect on lumbar degenerative diseases, and could change spine-pelvic sagittal parameters of patient to a certain extent, and further restoring the balance of the sagittal plane of lumbar spine.

Abstract
Objective: To evaluate the feasibility and efficacy of partial superficial parotidectomy with V-shaped incision by comparing with the Blair incision and hairline N-shaped incision. Methods: From January 2015 to January 2016, 60 patients (47 males and 13 females, with an age range of 25- 63 years) required for superficial partial parotid gland resection were randomly divided into three groups: V-shaped incision (VI) group, Blair incision (BI) group and hairline N-shaped incision (NI) group, with 20 cases in each group.Intraoperative, postoperative and follow-up indexes were compared between three groups. Operative time and drainage volume in the surgery of tumors at different sites in VI group were compared. SPSS18.0 software was used for statistic analysis. Results: There were no statistically significant differences among the three groups in operative time, drainage volume, postoperative hospital stay, periauricular numbness, fistulas, pain score, facial palsy, and scar score at the 3rd month after surgery (P>0.05). For appearance satisfaction score at the 6th month after surgery, VI group was better than BI group or NI group, with significant differences(VI group vs. BI group: 9.00[8.00, 9.00] vs. 5.00[4.00, 5.25], χ(2)=6.629, P<0.001; VI group vs. NI group: 9.00[8.00, 9.00] vs. 7.00[6.00, 8.00], χ(2)=2.942, P=0.010; BI group vs. NI group: 5.00[4.00, 5.25] vs. 7.00[6.00, 8.00], χ(2)=-3.687, P=0.001). For tumors located in the front, upper and middle of parotid gland, there were no statistically significant differences in operative time and drainage volume between the three groups (P>0.05). For tumors located at the lower part of parotid gland, the difference in operative time between the three groups was statistically significant (F=7.278, P=0.01). With pairwise comparison, operative time in VI group was longer than that in BI group or NI group, but there was no significant difference between BI group and NI group (VI group vs. BI group: (181.00±22.89) min vs. (132.50±9.01) min, t=3.694, P=0.004; VI group vs. NI group:(181.00±22.89) min vs. (149.00±15.94) min, t=2.585, P=0.025; BIgroup vs. NI group, (132.50±9.01) min vs. (149.00±15.94) min, t=1.257, P=0.235). For tumors located at the lower part of parotid gland, the differences in intraoperative drainage volume were not statistically significant between three groups (P>0.05). There were no statistically significant differences in operative time and drainage volume in the surgery of tumors at different sites in VI group (P>0.05). Conclusions: By use of V-shaped incision for the surgery of benign parotid gland tumors, the operation time of tumors located only in the lower part of the parotid gland will be prolonged. For tumors in different sites without increasing surgical complications, this modality can get good cosmetic effect.

Abstract
Objective: To determine whether 60 Gy is superior to standard 50 Gy for definitive concurrent chemoradiation(CCRT) in esophageal squamous cell carcinoma (ESCC) using modern radiation technology in a phase Ⅲ prospective randomized trial. Methods: From April 2013 to May 2017, 331 patients from 22 hospitals who were pathologically confirmed with stage ⅢA-ⅣA ESCC were randomized to 60 Gy or 50 Gy with random number table. Total of 305 patients were analyzed, including 152 in 60 Gy group and 153 in 50 Gy group. The median age was 63 years, 242(79.3%) males and 63(20.7%) females. The median length of primary tumor was 5.6 cm. The clinical characteristics between two groups were comparable. All patients were delivered 2 Gy per fraction, 5 fractions per week. Concurrent weekly chemotherapy with docetaxel (25 mg/m(2)) and cisplatin (25 mg/m(2)) and 2 cycles consolidation chemotherapy with docetaxel (70 mg/m(2)) and cisplatin (25 mg/m(2), d1-3) were administrated. The primary endpoint was local/regional progression-free survival (LRPFS). The data were compared with Pearson chi-square test or Fisher's exact test. Results: At a median follow-up of 27.3 months, the disease progression rate was 37.5% (57/152), 43.8% (67/153) in the high and standard-dose group, respectively (χ(2)=1.251, P=0.263). The 1, 2, 3-year LRPFS rate was 75.4%, 56.8%, 52.1% and 74.2%, 58.4%, 50.1%, respectively (HR: 0.95, 95%CI: 0.69-1.31, P=0.761). The 1, 2, 3-year overall survival rate was 84.1%, 64.8%, 54.1% and 85.4%, 62.9%, 54.0%, respectively (HR: 0.98, 95%CI: 0.71-1.38, P=0.927). The 1, 2, 3-year progression-free survival rate was 70.8%, 54.2%, 48.5% and 65.5%, 51.9%, 45.1%, respectively (HR: 0.93, 95%CI: 0.68-1.26, P=0.621). The incidence rates in toxicities between the two groups were similar except for higher rate of severe pneumonitis in high dose group (χ(2)=11.596, P=0.021). Conclusions: The efficacy in disease control is similar between 60 Gy and 50 Gy using modern radiation technology concurrent with chemotherapy for ESCC. The 50 Gy should be recommended as the regular radiation dose with CCRT for ESCC.
