Objective@#To determine human tear proteins using nanoliter liquid chromatography coupled to quadrupole orbitrap mass spectrometry (NanoLC-Q-Orbitrap-MS), and perform a bioinformatics analysis of main proteins.@*Methods@#Human tear samples were collected with capillary, transferred to 3 kDa ultrafiltration tubes containing 400 μL of superpure water and centrifuged at 12 000×g for 15 min. Repeated extraction of tear proteins were performed four times, and following digestion with trypsin, the proteins were separated using the Waters NanoAcquity peptide BEH C18 column (1.7 μm, 100 μm×100 mm) and determined using NanoLC-Q-Orbitrap-MS with the mobile phase of 0.1% formic acid aqueous solution and acetonitrile (0.1% formic acid) in the full MS/dd-MS2 mode. The types of proteins were characterized in the Uniprot database using the software Proteome Discoverer version 2.1 and verified using bovine serum albumin. The tear proteins were subjected to gene annotation analysis using the String database.@*Results@#A total of (387±160) human tear proteins were yielded, with a relative standard deviation (RSD) of 4.13%, and there were 25 types of proteins with a relative high abundance, including lipocalin 1, lysozyme and lactoferrin. The peptide sequence coverage of bovine serum albumin was (86.08±2.61)%, with a RSD of 3.03%. The 25 major tear proteins were involved in substance transduction among cells, homeostasis process, negative regulation of the endopeptidase activity, detection of chemical stimulants and humoral immune responses, and the 16 proteins had close interactions. Lacritin, lipocalin 1, lactoferrin, lysozyme and zinc-α 2-glycoprotein, which had a relative high abundance, had close biological connections.@*Conclusion@#NanoLC-Q-Orbitrap-MS is stable, reliable and feasible for detection of multiple proteins in tears.

Circular RNA Vaccines against SARS-CoV-2 and Emerging Variants

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its emerging variants of concern (VOC), such as Delta (B.1.617.2) and Omicron (B.1.1.529), has continued to drive the worldwide pandemic. Therefore, there is a high demand for vaccines with enhanced efficacy, high thermostability, superior design flexibility, and fast manufacturing speed. Here, we report a circular RNA (circRNA) vaccine that encodes the trimeric RBD of SARS-CoV-2 Spike protein. Without the need of nucleotide modification, 5-capping or 3-polyadenylation, circRNA could be rapidly produced via in vitro transcription and is highly thermostable whether stored in naked or lipid-nanoparticle (LNP)-encapsulated format. LNP-encapsulated circRNARBD elicited potent neutralizing antibodies and T cell responses, providing robust protection against Beta (B.1.351) and native viruses in mice and rhesus macaques, respectively. Notably, circRNA vaccine enabled higher and more durable antigen production than 1m{Psi}-modified mRNA vaccine, eliciting a higher proportion of neutralizing antibodies and stronger Th1-biased immune responses. Importantly, we found that circRNARBD-Omicron vaccine induced effective neutralizing antibodies against only Omicron but not Delta variant. By contrast, circRNARBD-Delta could elicit high level of neutralizing antibodies against both Delta and Omicron. Following two doses of either native- or Delta-specific vaccination, circRNARBD-Delta, but not Omicron or Beta vaccines, could effectively boost the neutralizing antibodies against both Delta and Omicron variants. These results suggest that circRNARBD-Delta is a favorable choice for vaccination to provide a broad-spectrum protection against the current variants of concern of SARS-CoV-2.

Bioinformatics Analysis of long non-coding RNA TUG1 in hepatocellular carcinoma / 国际检验医学杂志

Objective To explore the significance of long non-coding RNA (lncRNA) taurine up-regulated gene 1 (TUG1) in hepatocellular carcinoma (HCC),to predict the target gene of TUG1,and to provide a ref-erence for further study of TUG1 in HCC.Methods The differential expression of TUG1 in HCC was ana-lyzed by using the UALCAN database and the survival analysis of TUG1 was performed.The target gene of TUG1 was predicted by RegRNA 2.0 biology software,HMDD,targetscan and microT-CDS,and the regulato-ry network of lncRNA TUG1-microRNAs-mRNAs was constructed.The predicted target gene was analyzed by Gene Ontology (GO) and KEGG signal transduction pathway enrichment by using FunRich platform. Results TUG1 expression in HCC was significantly increased,and the expression level of TUG1 increased generally with the increase of tumor grade.The overall survival of patients with low expression of lncRNA TUG1 was significantly longer than that of lncRNA TUG1 high expression patients.There were four possible binding sites of HCC related microRNAs (hsa-mir-122-5p,hsa-mir-200a-3p,hsa-mir-34c-3p,hsa-mir-629-3p) on TUG1,which regulated 245 downstream target genes and formed the regulatory network of lncRNA TUG1-microRNAs-mRNAs.In the biological process,microRNA target genes were highly enriched in the processes such as the regulation of nucleobase,nucleoside,nucleotide and nucleic acid metabolism.In KEGG pathway analysis,microRNA target genes were highly enriched to the signal pathways mediated by Syndecan and TRAIL.Conclusion TUG1 expression level in HCC increased.Increased expression of TUG1 is associat-ed with poor prognosis in HCC.Bioinformatics methods can be used to explore the mechanism of tumorigene-sis from the molecular level,which can provide valuable information for subsequent experiments and clinical diagnosis and treatment.

Objective To explore the relationship between DNA methyctransferace1(DNMT1)gene polymorphism and cognitive function in the first episode, drug-na?ve schizophrenia. Methods One hundred eighty-six first episode, drug-na?ve schizophrenia patients and 182 healthy controls were examined by using polymerase chain reaction (PCR), denaturing polyacrylamide gel electrophoresis and silver staining to determine genotype and allele of DNMT1 gene. Cognitive function was assessed by using the standardized measurement tools—the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery (MCCB) Chinese version. Comparisons were made on the cognitive function and the genotype and allele distribution of SNP rs2114724 and rs2228611 between schizophrenia group and the control group.The relationship between DNMT1 gene polymorphism and cognitive function was analyzed. Results There was no significant difference of the genotype T/T, T/C, C/C and allele T, C distribution of SNP rs2114724 between schizophrenia group and healthy controls group (P>0.05). There was no significant difference of the genotype G/G, G/A, A/A and allele G, A distribution of SNP rs2228611 between schizophrenia group and healthy control group (P>0.05). There was significant difference in Spatial Span Test (SST) scores(P<0.05)among three different genotype T/T,T/C and C/C of rs2114724 in schizophrenic group.The SST scores of the patients with C/C genotype were higher than that of the patients with T/T or T/C genotype (P<0.05). Conclusion DNMT1 gene polymorphisms is not associated with the first-episode, drug-na?ve schizophrenia, but may be associated with the work memory in cognitive function of schizophrenia in the Chinese Han population.

[Effect of Al2O3 sandblasting on the bond strength between 3mol% yttrium-stabilized tetragonal zirconium polycrystal zirconia framework and veneering porcelain].

OBJECTIVE: The effect of sandblasting on the bond strength between 3mol% yttrium-stabilized tetragonal zirconium polycrystal (3Y-TZP) zirconia framework and veneering porcelain was evaluated. METHODS: A total of 21 specimens [(25 ± 1) mm x (3 ± 0.1) mmx (0.5 ± 0.05) mm] were prepared according to ISO 9693. The specimens were then randomly divided into 3 groups. Sandblasting was performed on 2 meshes of Al2O3 particles: group A with mesh 110 and group B with mesh 80. Group C, which was not sandblasted, was the control group. The surface roughness of the zirconia framework, as well as the bond strength between 3Y-TZP zirconia framework and veneering porcelain, was measured. The interface microstructure was observed by scanning electron microscope (SEM), and elemental distribution was detected by energy dispersive spectroscopy (EDS). RESULTS: Surface roughness values were (1.272 ± 0.149) µm for group A, (0.622 ± 0.113) µm for group B, and (0.221 ± 0.065) µm for group C. Statistical significance were found among groups (P < 0.05). The bond strength values were (28.21 ± 1.52) MPa for group A, (27.71 ± 1.27) MPa for group B, and (24.87 ± 3.84) MPa for group C. Statistical significance was found between group A and group C (P < 0.05), whereas the other groups had no statistical significance (P > 0.05). Interface adhesion failure was the primary performance. SEM images showed the close interface bonding, and EDS showed that the interface had no obvious element penetration. CONCLUSION: Al2O3 sandblasting can slightly enhance the bond strength between zirconia framework and veneering porcelain.

Mechanism of Bu-Shen Kang-Shuai Tablet on Oxidative Stress in Atherosclerosis / 世界科学技术-中医药现代化

This study was aimed to determine effect of Bu-Shen Kang-Shuai (BSKS) Tablet on HO-1 mRNA and its associated oxidative stress levels among atherosclerotic rabbits. A total of 56 rabbits were randomly divided into the normal group (8 rabbits) and the experimental group (48 rabbits). Normal diet was given to the normal group. Atherosclerotic rabbits models were established in the experimental group. At the eighth week, rabblits in the experi-mental group were randomly divided into the model group, BSKS Tablet group and simvastatin group. Blood samples were collected before medication, 8-, 12-, 16-week after medication from rabbits of each group. Rabbits were sacri-ficed under aseptic conditions at the last blood collection. Expressions of aortic HO-1 mRNA and PPARα mRNA were measured by Q-PCR method. The level of MMP-9 was measured by immunohistochemical assay. Serum HbCO, COX-2 activity and cGMP level were measured by ELISA assay. The results showed that after the intervention of BSKS Tablet, serum HbCO level decreasd, cGMP was obviously increased. However, there was no obvious change on the COX-2 activity. The immunohistochemical assay showed that BSKS Tablet obviously reduced MMP-9 level of rabbits. There was only small amount of aortic HO-1 mRNA expression in the normal group. However, the expres-sion of aortic HO-1 mRNA in the atherosclerosis group was increased. After intervention of BSKS Tablet, the ex-pression of HO-1 mRNA was increased with statistical significance (P < 0.05). Simvastatin had similar antioxidant effect. It was concluded that the compound preparation of traditional Chinese medicine (TCM) BSKS Tablets had an important antioxidant effect in treatment of atherosclerosis. Its protective mechanism may be through the regulation of HO-1 mRNA gene expression and effects of HO-1/CO-cGMP pathway activities of related enzymes while peroxida-tion stability of atherosclerotic plaque.
