Abstract
Amino acids are the building blocks of proteins and are widely used as important ingredients for other nitrogen-containing molecules. Here, we report the sustainable production of amino acids from biomass-derived hydroxy acids with high activity under visible-light irradiation and mild conditions, using atomic ruthenium-promoted cadmium sulfide (Ru1/CdS). On a metal basis, the optimized Ru1/CdS exhibits a maximal alanine formation rate of 26.0 molAla·gRu‑1·h‑1, which is 1.7 times and more than two orders of magnitude higher than that of its nanoparticle counterpart and the conventional thermocatalytic process, respectively. Integrated spectroscopic analysis and density functional theory calculations attribute the high performance of Ru1/CdS to the facilitated charge separation and O-H bond dissociation of the a-hydroxy group, here of lactic acid. The operando nuclear magnetic resonance further infers a unique "double activation" mechanism of both the CH-OH and CH3-CH-OH structures in lactic acid, which significantly accelerates its photocatalytic amination toward alanine.

Abstract
It has been well-established that light-matter interactions, as manifested by diverse linear and nonlinear optical (NLO) processes, are mediated by real and virtual particles, such as electrons, phonons, and excitons. Polarons, often regarded as electrons dressed by phonons, are known to contribute to exotic behaviors of solids, from superconductivity to photocatalysis, while their role in materials' NLO response remains largely unexplored. Here, the NLO response mediated by polarons supported by a model ionic metal oxide, TiO2, is examined. It is observed that the formation of polaronic states within the bandgap results in a dramatic enhancement of NLO absorption coefficient by over 130 times for photon energies in the sub-bandgap regions, characterized by a 100 fs scale ultrafast response that is typical for thermalized electrons in metals. The ultrafast polaronic NLO response is then exploited for the development of all-optical switches for ultrafast pulse generation in near-infrared (NIR) fiber lasers and modulation of optical signal in the telecommunication band based on evanescent interaction on a planar waveguide chip. These results suggest that the polarons supported by dielectric ionic oxides can fill the gaps left by dielectric and metallic materials and serve as a novel platform for nonlinear photonic applications.

Abstract
Objective: To investigate the associations of cardiometabolic multimorbidity (CMM) with grip strength and gait speed among older Chinese adults. Methods: This study included participants aged ≥60 years from the China Health and Retirement Longitudinal Survey during 2011-2015. Generalized estimating equation models were employed to estimate the associations of CMM with grip strength and gait speed. Results: A total of 6 357 participants were included to measure grip strength and 6 250 participants to measure gait speed. Compared with no cardiometabolic disease, participants with 1 (β=-0.018, 95%CI: -0.026--0.010), 2 (β=-0.029, 95%CI: -0.041- -0.018), and ≥3 (β=-0.050, 95%CI: -0.063- -0.037) cardiometabolic diseases were associated with a decreased grip strength. The associations between cardiometabolic disease counts (1: β=-0.052, 95%CI: -0.326-0.222; 2: β=-0.083, 95%CI: -0.506-0.340; ≥3: β=-0.186, 95%CI: -0.730-0.358) and gait speed were not statistically significant. The predictive value of gait speed of the participants with 0, 1, 2, and ≥3 cardiometabolic diseases were found to be 1.98 (95%CI: 1.38-2.58), 1.93 (95%CI: 1.34-2.51), 1.89 (95%CI: 1.18-2.61), and 1.79 (95%CI: 1.10-2.48) m/s respectively, which was clinically significant for the magnitude of the decrease. Cardiometabolic combinations with a higher risk of decreased grip strength and gait speed mainly seen in diabetes. Conclusions: Cardiometabolic disease counts and combinations were associated with grip strength and gait speed. Grip strength and gait speed can be used to measure CMM severity.

Abstract
BACKGROUND Circular RNA (circRNA) has been proved to be an important regulator of gastric cancer (GC). However, the role and regulatory mechanism of circrna related competitive endogenous RNA (ceRNA) in GC have not been established. METHODS CircRNA data and clinical data were obtained from the GEO and TCGA databases. The ceRNA networks were constructed and a function enrichment analysis was completed. Additionally, correlations between hub genes expression, immune cell infiltration, and clinical phenotypes were determined. The differentially expressed circRNAs and their downstream microRNAs (miRNAs) were validated by quantitative real-time polymerase chain reaction, and the hub genes were validated by western blot analysis. The migration and invasion ability of overexpressed hsa_circ_0002504 was determined by a transwell assay. RESULTS The ceRNA network contained 2 circRNAs, 3 miRNAs, and 55 messenger RNAs (mRNAs). 323 biological processes terms, 53 cellular components terms, 51 molecular functions terms, and 4 signaling pathways were revealed by the function enrichment analysis. The GSEA analysis revealed that the hub genes were positively correlated with the axon guidance and adhesion molecules pathways. The correlation analysis revealed that overexpressed EPHA4 and KCNA1 indicated poor tissue differentiation and were associated with clinically advanced stages of GC. The in vitro experiments showed that hsa_circ_0002504 was significantly down-regulated in GC cell lines. In addition, the overexpression of hsa_circ_0002504 led to a significant downregulation of hsa-miR-615-5p and hsa-miR-767-5p, as well as an upregulation of EPHA4, KCNA1, and NCAM1. Furthermore, it suppressed the migration and invasion ability of GC cells. CONCLUSIONS Hsa_circ_0002504 is a potential diagnostic biomarker for GC. High expression of EPHA4 and KCNA1 may indicate poor prognosis.

Abstract
Background Hsa_circ_0072309 has been identified as a tumor suppressor in several carcinomas. However, its precise role in gastric cancer (GC) remains largely unknown. This study was aimed to explore the precise role of Hsa_circ_0072309 in GC. Methods The transcriptional and clinical data of stomach adenocarcinoma were downloaded using the University of California SantaCruz (UCSC) Xena browser. The circular RNA (circRNA) datasets were obtained from the Gene Expression Omnibus (GEO) database. The expression profile and survival analysis of differentially expressed micro RNAs (DEMIs) and differentially expressed messenger RNAs (DEMs) were performed. Correlations between the expression and immune infiltration of the DEMS were studied. Additionally, the expression of hsa_circ_0072309 in GC tissues and cell lines were validated, and the relationship between its expression and clinical features was investigated. Gain- and loss-of function experiments and molecular interaction experiments were also conducted. Results Overall, 7 differentially expressed circRNAs, 13 DEMIs, and 17 DEMs were screened. Two DEMIs (hsa_miR-34a-3p and hsa_miR-326) and five DEMs (C7, MARCKSL1, UBE2T, OLR1, and HOXC11) showed significant differences in the high- and low-risk groups. The most significantly enriched Gene Ontology terms were the circadian regulation of gene expression and protein binding. The most significantly enriched Kyoto Encyclopedia of Genes and Genomes pathways were the PI3K-Akt and Ras signal pathways. Additionally, six genes were significantly correlated with immune infiltration. The real-time quantitative PCR (RT-qPCR) results revealed a significant downregulation of hsa_circ_0072309 in GC tissues related to tumor size, vascular invasion, and lymph node metastasis. A hsa_circ_0072309 overexpression suppressed whereas a hsa_circ_0072309 knockdown promoted GC cells proliferation and migration in vitro; in addition, hsa_circ_0072309 could directly bind to has-miR-34a-3p and has-miR-330-5p. Conclusions Hsa_circ_0072309 is a potential diagnostic biomarker for GC, and complement component 7 may be a tumor suppressor. These may potentially predict the prognosis of patients with GC and may become new therapeutic targets.

Abstract
Objectives: To analyze the current development status of gastric cancer (GC) randomized controlled trials (RCT) between 2000 and 2019, and to review the basic characteristics of published RCT. Methods: ClinicalTrials.gov was searched for phase 3 or 4 RCT conducted between January 2000 and December 2019 with the keyword "gastric cancer", and the development trend of different types of RCT during different time periods was described. Basic features of registered RCT such as intervention, study area, single-center or multicenter, sample size, and funding were presented. PubMed and Scopus databases were searched to judge the publication status of studies completed until June 2016. The adequacy of the report was estimated by the Consolidated Standards of Reporting Trials (CONSORT) checklist. Design flaws were evaluated by Cochrane tool and/or whether a systematic literature review was cited. The data was analyzed by χ2 test or Fisher exact test. Results: There were 262 RCT including in the present study. The number of GC-RCT registered on ClinicalTrials.gov had been on the rise from 1 case in 2000 to 30 cases in 2015. The proportion of RCT associated with targeted therapy or immunotherapy increased from 0 during 2000-2004 to 37.1% (36/97) during2015-2019. The RCT registered in Asia was 191 cases, while that in non-Asia region was 71 cases. The proportion of multi-center RCT from non-Asia was higher than that from Asia (70.4% (50/71) vs. 50.3% (96/191), χ²=8.527, P=0.003). The proportion of RCT published was 59.1% (81/137). Among the published RCT, 65 (80.2%) studies were reported adequately, but 63 (77.8%) studies had avoidable design limitations. Conclusions: Targeted therapy and immunotherapy have become research hotspots in the treatment of GC. At present, there are inadequate multicenter RCT in Asia, and the publication rate of RCT is low. A considerable number of published RCT are reported inadequately and have avoidable design flaws.

The proportion of RCT associated with targeted therapy or immunotherapy increased from 0 during 2000-2004 to 37.1% (36/97) during 2015-2019. The RCT registered in Asia was 191 cases, while that in non-Asia region was 71 cases. The proportion of multi-center RCT from non-Asia was higher than that from Asia (70.4% (50/71) vs. 50.3% (96/191), χ²=8.527, P=0.003). The proportion of RCT published was 59.1% (81/137). Among the published RCT, 65 (80.2%) studies were reported adequately, but 63 (77.8%) studies had avoidable design limitations. Conclusions: Targeted therapy and immunotherapy have become research hotspots in the treatment of GC. At present, there are inadequate multicenter RCT in Asia, and the publication rate of RCT is low. A considerable number of published RCT are reported inadequately and have avoidable design flaws.

Abstract
Objective: To explore the relationship between obesity status and death stratified by different multi-morbidity status in older adults in China. Methods: Data for older Chinese adults aged ≥65 years were from Chinese Longitudinal Healthy Longevity Survey (CLHLS). Multi-morbidity patterns based on 13 chronic conditions were explored using exploratory factor analysis. Cox models were used to examine relationships between obesity status and death stratified by disease count and multi-morbidity patterns at baseline, respectively. Besides, obesity status was defined by baseline body mass index and waist circumference. Results: A total of 6 272 participants were included in the analyses. Multi-morbidity including cardio-metabolic, sensory perception and other patterns were identified. For those without any chronic condition, compared with those without central obesity, central obesity was associated with a higher risk for death (HR=1.66, 95%CI:1.04-2.66). For those only with one chronic condition, compared with normal weight, underweight was associated with a higher risk for death (HR=1.41, 95%CI: 1.10-1.80). For those with multi-morbidity, compared with normal weight, underweight increased the risk for death (HR=1.19, 95%CI:1.05-1.34). Compared with those without central obesity, central obesity decreased the risk for death (HR=0.88, 95%CI:0.78-0.99). Conclusions: Relationships between obesity status and death varied by multi-morbidity status in older adults in China. Underweight and non-central obesity were associated with increased risks for death in older adults with only one chronic disease or multi-morbidity. Therefore, it is necessary to pay attention to multi-morbidity status in the management of obesity in older adults and provide effective targeted body weight management plan.

Abstract
Objective To explore the correlation between changes in esophageal pressure and psychological status in patients with globus sensation. Methods A total of 40 patients with globus sensation who attended Wenzhou People’s Hospital between August 2020 and February 2021 were divided into two groups based on the results of esophageal manometry: a high-pressure group and a non-high-pressure group. The duration of disease, clinical symptom score, and self-rating anxiety scale (SAS) were compared between the two groups to determine the relationship between changes in esophageal pressure and psychological status. Results All the patients before treatment were divided into a high-pressure group (n = 14) and a non-high-pressure group (n = 26) according to whether the resting pressure of the upper esophageal sphincter (UES) was greater than 104 mmHg. The differences between the high-pressure group and non-high-pressure group in duration of disease, clinical symptom score, and SAS were statistically significant (all P < 0.05). Anxiety was present in 12 patients in the high-pressure group and two patients in the non-high-pressure group. The difference between the the high-pressure group and non-high-pressure group in the incidence of anxiety was statistically significant (χ2 = 21.04 and P < 0.001). Pearson correlation analysis of the association between esophageal pressure and anxiety resulted in R = 0.74 and P < 0.001. Conclusion Patients with globus sensation who develop anxiety were more likely to have high pressure in the upper esophageal sphincter.

Abstract
Detailed information about the influences of the cooperative motion of water and methanol molecules on practical solid-liquid heterogeneous photocatalysis reactions is critical for our understanding of photocatalytic reactions. The present work addresses this issue by applying operando nuclear magnetic resonance (NMR) spectroscopy, in conjunction with density functional theory (DFT) calculations and ab initio molecular dynamics (AIMD) simulations, to investigate the dynamic behaviors of heterogeneous photocatalytic systems with different molar ratios of water to methanol on rutile-TiO2 photocatalyst. The results demonstrate that methanol and water molecules are involved in the cooperative motions, and the cooperation often takes the form of methanol-water clusters that govern the number of methanol molecules reaching to the active sites of the photocatalyst per unit time, as confirmed by the diffusion coefficients of the methanol molecule calculated in the binary methanol-water solutions. Nuclear Overhauser effect spectroscopy experiments reveal that the clusters are formed by the hydrogen bonding between the -OH groups of CH3OH and H2O. The formation of such methanol-water clusters is likely from an energetic standpoint in low-concentration methanol, which eventually determines the yields of methanol reforming products.

Abstract
Understanding the role of different solvent molecules for practical solid-liquid heterogeneous photocatalytic reactions is critical for determining the pathway of the reaction. In this study, the operando nuclear magnetic resonance (NMR) method, combined with density functional theory (DFT) calculations, was employed to evaluate the control effect of solvent water in the photocatalytic reforming mechanism of methanol with a Pt-TiO2 catalyst. Results indicate that the presence of water effectively promotes the formation of the HCHO intermediate but inhibits the H2 evolution originating from the switch of the hydrogen source of the H2 formation from CH3OH to H2O. More interestingly, as detected directly in the ab initio molecular dynamics simulation, a small amount of H2O can dissociate, and the evolved -OH species at Ti5c site can greatly reduce the C-H activation barrier of -CH3O, contributing to the formation of oxidation products (e.g., HOCH2OH and CH3OCH2OH) on the Pt-TiO2 surface.

Abstract
Objective: To study the value of Saccharomyces boulardii for the prevention of antibiotic-associated diarrhea in older inpatients. Methods: A total of 163 older patients who were treated with wide-spectrum antibiotics at least three days during January 2014 to December 2015 were randomly divided into control and study group. In study group, 81 patients were administrated with oral Saccharomyces boulardii 500 mg twice a day for 21 days. The control group was of no intervention. Morbidity rate of antibiotic-associated diarrhea and Clostridium difficile-associated diarrhea, frequency and duration of diarrhea were recorded. Results: The incidence of antibiotic-associated diarrhea in study group was significantly lower than that in control group [14.8%(12/81) vs 28.0%(23/82), P<0.05], whereas no difference was seen in the incidence of Clostridium difficile-associated diarrhea [3.7%(3/81) vs 4.9%(4/82), P>0.05] in two groups. The frequency and duration of diarrhea in the study group were significantly lower and shorter than those in control group[(4.3±1.7) times/day vs (6.9±2.0) times/day; (3.0±1.1) days vs (5.7±1.8) days, both P<0.01]. Conclusion:Saccharomyces boulardii may reduce the incidence of antibiotic-associated diarrhea therefore improving the symptom of diarrhea in older inpatients.

Abstract
Objective To examine if the hospitalisation trends of liver cirrhosis are changing with the changes of risk factors of the disease in China. Design Secondary analysis of hospitalisation records in the 31 top-ranking hospitals in Beijing. Results Between 2006 and 2010, hospitalisation from viral hepatitis cirrhosis (VHC) decreased by 10% (95% CI=5–14%, p<0.001), but non-viral hepatitis cirrhosis (NVHC) and alcoholic cirrhosis (AC) increased by 35% (26–46%, p<0.001) and 33% (19%– 47%, p<0.001), respectively. The age patterns of hospitalisation varied with different types of liver cirrhosis. The hospitalisation risks for patients with VHC and AC were significantly high in the age groups 40–49 and 50–59 years, but risks for those with NHVC were high in all age groups of 40 years or above. Overall male-to-female hospitalisation ratios for VHC, NVHC and AC were 2.71, 1.14 and 59.9, respectively. The sex ratio became smaller with time from 2006 to 2010 in hospitalised patients with VHC, but it substantially increased in those with NVHC during the same period. Conclusions Hospitalisation rates for liver cirrhosis in Beijing are changing with time. The changes of viral hepatitis infection and alcohol consumption in the general population may cause these changes.

Abstract
Colchicine (COL), an alkaloid derived from plants, has been used to treat gout, pseudogout and familial Mediterranean fever for several decades. The purpose of this study was to investigate the in vivo effect of COL on rat cytochrome P450 enzymes (CYP1A2, CYP2C9, CYP2C19 and CYP2D6) to assess its potential to interact with co-administered drugs. This was a randomized, double-blind, two-way crossover study with a 4-week washout period between the phases. Rats received COL via an irrigation stomach needle at a dose of 0.4 mg/kg once daily for consecutive 10 days. On the eleventh day, a cocktail solution at a dose of 4 ml/kg, which contained phenacetin (15.0 mg/kg), tolbutamide (3.0 mg/kg), omeprazole (15.0 mg/kg) and dextromethorphan (15.0mg/kg), was oral administered to all rats. Then 0.3 ml blood samples were collected at a set of time-points. The plasma concentrations of probe drugs were simultaneously determined by HPLC-MS/MS. Pharmacokinetic parameters simulated by DAS software were used for the evaluation of COL on the activities of rat CYP1A2, CYP2C9, CYP2C19 and CYP2D6 enzymes. Our study showed that COL administration induced CYP2C9 activity, causing a significant decrease in AUC(0-infinity) (P < 0.01) and t1/2 (P < 0.05) of tolbutamide, and a distinct increase in CL (P<0.01). Many pharmacokinetic parameters of dextromethorphan in COL-treated rats were affected significantly, which indicated that the metabolism of dextromethorphan in these treatment groups was evidently slowed down. However, there was no significant influence of pharmacokinetic parameters of phenacetin and omeprazole in COL-treated rats. The results from the present in vivo study suggested that COL showed no effects on rat CYP1A2 and CYP2C19, however, it demonstrated potential inductive effects on CYP2C9 and inhibitory effects on CYP2D6. Therefore, caution is needed when COL is co-administered with drugs metabolized by CYP2C9 or CYP2D6, which may result in altered plasma concentrations of these drugs and relevant drug-drug interactions.

Abstract
We have investigated the role of ginsenoside Re (Re) in preventing 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced apoptosis of the substantia nigra neurons in the mouse model of Parkinson's disease (PD). C57BL mice have been administrated i.s.c. with MPTP to establish the PD model. Pretreatment groups were given different doses of Re (6.5, 13, 26 mg kg(-1)) i.g. for 13 days. Transmission electron microscope (TEM), tyrosine hydroxythase (TH) immunostaining and TDT-mediated dUTP nick-end labeling (TUNEL) staining have been used to observe the damage of substantia nigral neurons. To measure the expression of inducible nitric oxide synthase (iNOS), Bcl-2, Bax protein and expression of Bcl-2, Bax gene, immunohistochemistry and in situ hybridization have been explored respectively. Western blot analysis has been performed with anti-caspase-3. Pretreatment with Re (13, 26 mg kg(-1)) markedly increases TH-positive neurons and decreases the TUNEL-positive ratio compared with the MPTP model group. Furthermore, Re could enhance the expression of Bcl-2 protein and Bcl-2 mRNA, but reduce the expression of Bax, Bax mRNA, and iNOS, and weaken the cleavage of caspase-3. In summary, ginsenoside Re showed protection from MPTP-induced apoptosis in the PD model mouse nigral neurons and this effect may be attributable to upregulating the expression of Bcl-2 protein, downregulating the expression of Bax, and iNOS protein, and inhibiting the activation of caspase-3.

Abstract
The effect of (3,5,6-trimethylpyrazin-2-yl)methyl 2-[4-(2-methylpropyl)phenyl]propanoate (ITE) on type II collagen (CII)-induced arthritis in mice was studied. Mice were immunized twice with CII, ITE being given orally once a day for 40 d after the 1st immunization. Clinical assessment showed that ITE had no effect on the day of onset of arthritis but did lowered the incidence rate of arthritis and the arthritis score. And ITE had a marked suppressive effect on the mouse hind paw edema induced by CII. ITE suppressed the delayed-type mouse ear skin reaction to CII but had no effect on the level of serum anti-CII antibodies. These results suggest that ITE inhibits the development of CII-induced arthritis in mice by suppressing delayed-type hypersensitivity to CII.

Abstract
We have isolated and sequenced cDNAs for S2- and S3-alleles of the self-incompatibility locus (S-locus) in Solanum chacoense Bitt., a wild potato species displaying gametophytic self-incompatibility. The S2- and S3-alleles encode pistil-specific proteins of 30 kDa and 31 kDa, respectively, which were previously identified based on cosegregation with their respective alleles in genetic crosses. The amino acid sequence homology between the S2- and S3-proteins is 41.5%. This high degree of sequence variability between alleles is a distinctive feature of the S-gene system. Of the 31 amino acid residues which were previously found to be conserved among three Nicotiana alata S-proteins (S2, S3, and S6) and two fungal ribonucleases (RNase T2 and RNase Rh), 27 are also conserved in the S2- and S3-proteins of S. chacoense. These residues include two histidines implicated in the active site of the RNase T2, six cysteines, four of which form disulfide bonds in RNase T2, and hydrophobic residues which might form the core structure of the protein. The finding that these residues are conserved among S-proteins with very divergent sequences suggests a functional role for the ribonuclease activity of the S-protein in gametophytic self-incompatibility.
