AIM: Age-related macular degeneration (AMD) is the leading cause of blindness in the developed world and complement factor H (CFH) polymorphism has been found to associate with the AMD. To investigate whether the Y402H variant in CFH is associated with AMD in Chinese populations, a systematic review and meta-analysis were performed to estimate the magnitude of the gene effect and the possible mode of action. METHODS: A meta-analysis was performed using data available from ten case-control studies assessing association between the CFH Y402H polymorphism and AMD in Chinese populations involving 1538 AMD. Data extraction and study quality assessment were performed in duplicate. Summary odds ratios (ORs) and 95% confidence intervals (CIs) an allele contrast and genotype contrast were estimated usingfixed- effects models. The Q-statistic test was used to assess heterogeneity, and Funnel plot was used to evaluate publication bias. RESULTS: Seven of ten case-control studies were neovascular AMD, and few studies came from west and north of China. There was strong evidence for association between CFH and AMD in Chinese population, with those having risk allele C 2.35 times more likely to have AMD than subjects with T allele. Evidence of publication bias was not observed in our meta-analysis. CONCLUSION: This meta-analysis summarizes the strong evidence for an association between CFH and AMD in Chinese and indicates each C allele increasing the odds of AMD by 2.33-fold. But more evidences about the relation between CFH polymorphism and different type of Chinese AMD from various district were needed. 展开更多

AIM:To determine the outcome of non-investigational treatment with intravitreal bevacizumab(IVB) in neovascular age-related macular degeneration(AMD)patients.· METHODS:Retrospective chart review of 81 eyes with neovascular AMD followed-up for at least 12 mo and received 3-monthly loading IVB injections.Re-treat was based upon the individual clinician's judgment.Bestcorrected visual acuity(BCVA) and optical coherence tomography measurements of central foveal thickness outcomes were evaluated at 12,24 mo.· RESULTS:Eighty-one eyes(of 75 patients) completed12 mo of follow-up and 44 eyes(of 41 patients) completed24 mo of follow-up.The mean baseline logMAR BCVA significantly improved from 0.94±0.69 to 0.85±0.68 at12mo(P〈0.001) and from 0.91±0.65 to 0.85±0.60(P=0.004)at 24 mo.The proportion of eyes that lost 〈15 logMAR letters at 12 mo was 90.1%and at 24 mo was 81.8%.IVB was effective in improving visual acuity in both treatment naive and previous photodynamic therapy(PDT)-treated subgroups.Treatment naive patients required significantly fewer injections than patients with prior PDT.Multiple regression analysis identified that poorer baseline visual acuity was associated with greater improvement in visual acuity(P=0.015).· CONCLUSION:Fewer injections in clinical practice may result in suboptimal visual outcomes compared with clinical trials of IVB in neovascular AMD patients.Poor baseline visual acuity and prior PDT treatment may also improve vision after IVB.The safety and durability of effect was maintained at 24 mo. 展开更多

BACKGROUND : c-fos and c-jun, the important immediate early genes (IEG), are regarded as the markers for the location and function of neuronal activity, as well as the third signal messengers, they couple the stress stimulation and the gene expression in neuron, and hippocampus is involved in the process of signal transmission after stress stimulation induced depression. OBJECTIVE: To observe the therapeutic effects of Bushen Yiqi (tonifying kidney to benefit qi), Huoxue Huayu (promoting blood circulation to dissipate blood stasis) and Ditan Kaiqiao (eliminating phlegm for resuscitation) on the expressions of c-Fos and c-Jun proteins in hippocampus and spontaneous behaviors of rats with post-stroke depression (PSD), and compare the results with those of fluoxetine, which is known to have definite effect on depression. DESIGN: A randomized controlled tna SETTING : Zhejiang College of Traditional Chinese Medicine MATERIALS : The trial was completed in Zhejiang College of Traditional Chinese Medicine from January to July in 2003. Fifty-six healthy adult Wistar male rats of clean grade, weighing (250±50) g, were randomly divided into 7 groups with 8 rats in each group: control group, model group, forced swimming group, Bushen Yiqi group; Huoxue Huayu, Ditan Kaiqiao group and fluoxetine group. The Bushen Yiqi Tang contained Renshen, Huangqi, Heshouwu, Gouqi, Shudi, etc., crude drugs 1 800 g/L. The Huoxue Huayu Tang contained Danshen, Chuanxiong, Chishao, Yujin, etc., crude drugs 3 600 g/L. The Ditan Kaiqiao Tang contained Banxia, Danxing, Changpu, Yuanzhi, etc., crude drug 1 000 g/b METHODS: ① Except the control group and forced swimming group, rats in the other groups were made into PSD models by deligating the bilateral common carotid artedes permanently. ② Rats in the control group, model group and forced swimming group were intragastncally perfused by saline (3 mL for each time); those in the Bushen Yiqi group, Huoxue Huayu, Ditan Kaiqiao group and fluoxetine group were intragastncally perfused with Bushen Yiqi Tang (18 g/kg), Huoxue Huayu Tang (9 g/kg), Ditan Kaiqiao Tang (9 g/kg) and fluoxetine (2.5 mg/kg) respectively, once a day. ③ At 55 days after model establishment, rats in the forced swimming group were managed according to the Porsolt's method. They were placed in water for 15 minutes, and then taken out and dned, no moving-time within 5 minutes was recorded at drying and 24 hours after drying. ④ Measurement of spontaneous behaviors: Except the forced swimming group, the spontaneous behaviors and activities (including horizontal and vertical movements) of rats were observed with the Open-Field method at 28, 42 and 56 days after administration in the other groups. ⑤ The expressions of c-Fos and coJun proteins in hippocampus were determined with the immunohistochemical method, the relative sectional area ratio and average objective gray value of c-Fos and c-Jun positive cells in hip- pocampus were measured with the computerized image analytical system. MAIN OUTCOME MEASURES: The spontaneous behaviors of rats, the relative sectional area ratio and average objective gray value of c-Fos and c-Jun positive cells in hippocampus were observed. RESULTS: Of the 56 rats, 1 died in the forced swimming group, and finally 55 rats were involved in the analysis of results. ① Results of spontaneous activities: At 28 days, the times of crossing movements were obviously fewer in the model group and fluoxetine group [(69.00±37.01), (98.11 ±36.68) times/3 minutes] than in the control group [(128.44±16.85) times/3 minutes, P 〈 0.01, 0.05], but those in the Bushen Yiqi group, Huoxue Quyu group and Ditan Kaiqiao group had no obvious differences as compared with those in the control group (P 〉 0.05). At 42 and 56 days, the times of crossing movements were obviously more in the Bushen Yiqi group, Huoxue Quyu group and Ditan Kaiqiao group [(106.44±31.24), (117.20±23.95), (134.80±28.18), (136.36±40.95) times/3 minutes; (117.33±35.91), (129.60 ±23.78), (131.90 ±26.81), (136.09±28.34) times/3 minutes] than in the model group [(64.00±17.51), (72.86±20.68) times/3 minutes, P 〈 0.01]. The times of rearing movements had no obvious differences among the groups for the three times (P 〉 0.05). ② The no moving-time within 5 minutes 24 hours after drying was obviously longer than that at drying in the forced swimming group. ③ The average objective gray values of c-Fos positive cells were not obviously different in the Bushen Yiqi group and Ditan Kaiqiao group from the control group (P 〉 0.05), but lower in the model group than in the control group (69.84±9.82, 75.78±5.89, P 〈 0.01), and higher in the forced swimming group than in the control group (85.97±10.99, P 〈 0.01); all higher in the fluoxetine group, Bushen Yiqi group, Huoxue Quyu group and Ditan Kaiqiao group than in the model group (81.27±10.73, 74.04±8.34, 83.29±9.89, 70.14±4.92, P 〈 0.05-0.01). The average objective gray values of c-Jun positive cells were obviously lower in the Bushen Yiqi group than in the control group (68.11 ±6.89, 79.58±5.86, P 〈 0.01), but all higher in the other groups than in the control group (84.68±7.15, 81.34 ±8.36, 97.51±10.55, 85.68±9.25, 86.19±10.98, P 〈 0.05-0.01); Those were obviously higher in the fluoxetine group, Huoxue Quyu group and Ditan Kaiqiao group than in the model group (P 〈 0.05-0.01 ), lower in the Bushen Yiqi group than in the model group (P 〈 0.05), all obviously lower in the Bushen Yiqi group, Huoxue Quyu group and Ditan Kaiqiao group than in the fluoxetine group (P 〈 0.01). The relative sectional area ratios of c-Fos and c-Jun positive cells had no obvious differences among the groups (P 〉 0.05). CONCLUSION : The methods of Bushen Yiqi, Huoxue Quyu and Ditan Kaiqiao can effectively treat PSD in rats, and the results were equivalent with those of fluoxetine, the actions of the above-mentioned drugs may correlated with their regulation to c-Fos and c-Jun expressions in hippocampus. PSD animal models can be successfully established by both permanent deligation of bilateral common carotid arteries and forced swimming, and the models induced by the former has similar basic cerebrovascular lesions as human stroke in clinic. 展开更多

This study intends to compare and contrast love expressions used by American and Chinese university students. The participants of 40 university students, including American male university students, American female university students, Chinese male university students, and Chinese female university students, were selected randomly. Each of them was given one questionnaire. There was an introductory question, which aimed at finding out whether the participants would choose to express their love in verbal or written language, and if they would, how they would express it. Then the participants were channeled into the four different parts. Results showed that male university students of both nations were more eager to express their love and also had less constraints and pressure compared with their female counterparts did. American university students of both genders were more open and direct when they expressed their love, whereas Chinese university students of both genders were more reserved and tended to express their love indirectly. 展开更多

The cDNA fragment encoding caffeic acid 3_O_methyltransferase (COMT) in Chinese white poplar ( Populus tomentosa Carr.) was isolated and cloned by RT_PCR technique. The size of the cDNA fragment is 1 080 bp, which almost covers the whole cDNA_encoding region. Authors’ cDNA fragment in P. tomentosa shares 98.7% homology with the reported corresponding cDNA in the P. tremuloids at nucleotide level, 99.4% homology at amino acid level, respectively. The analysis of Northern dot hybridization showed that COMT is expressed specifically in the developing secondary xylem of stem during the season of xylem differentiation, which means the linkage between the gene expression for a monolignol biosynthetic enzyme and seasonal regulation of xylem development in woody plant. 展开更多

CBF/DREB proteins play a critical role in abiotic stress-mediated gene expression and represent attractive regulons for plant breeding programs.However,no study has been conducted for CBF/DREB protein-related genes in jujube(Ziziphus jujuba Mill.).In this study,twenty-five ZjDREB genes were identified and annotated from the jujube(Z.jujuba‘Dongzao’)genome.Detailed analysis,including gene classification,annotation,phylogenetic evaluation,conserved motif determination and expression profiling were performed on all genes.Phylogenetic analysis showed that ZjDREB proteins were divided into five subgroups(A1–A5),but lacking a subgroup A6 corresponding to AtDREBs.The ZjDREB genes were distributed in nine of twelve chromosomes in the genome.Additionally,the expression patterns of the DREB genes under different abiotic stresses were investigated using q RT-PCR.Nineteen ZjDREB genes were down-regulated under low temperature,in contrast six ZjDREB genes(01,03,05,11,23 and 24)were up-regulated.Under drought,salinity and high temperature conditions,expression of ZjDREB03,09,10,14,15,17 and 20 genes were induced and showed similar expression patterns,suggesting that various stress conditions share common elements in the signaling pathway.The results suggest that the family of DREB genes play an important role in abiotic stresses in jujube,and provide a foundation for further functional studies of this important class of transcriptional regulators. 展开更多

As a member of the Frizzled family, Frizzled3 (FZD3) is a receptor of the canonical Wnt signaling pathway and plays a vital role in mammalian hair follicle developmental processes. However, its effects on wool traits are not clear. The objectives of this study were to identify the single nucleotide polymorphisms (SNPs) and the expression patterns of FZD3 gene, and then to determine whether it affected wool traits of Chinese Merino sheep (Xinjiang Type) or not. PCR-single stranded conformational polymorphism (PCR-SSCP) and sequencing were used to identify mutation loci, and general linear model (GLM) with SAS 9.1 was used for the association analysis between wool traits and SNPs. Quantitative real-time PCR (qRT-PCR) was used to investigate FZD3 gene expression levels. The results showed that six exons of FZD3 gene were amplified and two mutation loci were identified in exon 1 (NC_019459.2: g.101771685 T>C (SNP1)) and exon 3 (NC_019459.2: g.101810848, A>C (SNP2)), respectively. Association analysis showed that SNP1 was significantly associated with mean fiber diameter (MFD)(P=0.04) and live weight (LW)(P=0.0004), SNP2 was significantly associated with greasy fleece weight (GFW)(P=0.04). The expression level of FZD3 gene in skin tissues of the superfine wool (SF) group was significantly lower (P<0.05) than that of the fine wool (F) group. Moreover, it had a higher expression level (P<0.01) in skin tissues than in other tissues of Chinese Merino ewes. While, its expression level had a fluctuant expression in skin tissues at different developmental stages of embryos and born lambs, with the highest expression levels (P<0.01) at the 65th day of embryos. Our study revealed the genetic relationship between FZD3 variants and wool traits and two identified SNPs might serve as potential and valuable genetic markers for sheep breeding and lay a molecular genetic foundation for sheep marker-assisted selection (MAS). 展开更多

To determine differential expression of genie male sterility A/B lines in Chinese cabbage-pak-choi (Brassica campestris ssp. chinensis Makino var. communis Tsen et Lee), we used the RNA fingerprinting technique, cDNA-AFLP analysis, in different developmental stages and different tissues. While no obvious differential expressions were observed in rosette leaves, florescence leaves, and scapes, some differential expressions were found in alabstrums of A/B lines and among leaves, scapes and alabstrums. We analyzed the al-abstrums collected in different developmental stages with 10 primer combinations. We got a unique band between middle size alabstrums and large alabstrums in B line in one of the ten pair primers, and in another one pair, one band reflecting a higher gene-expression level in A line than that in B line was obtained. No unique bands were found with the other primer combinations. The bands reflecting different gene-expression level were confirmed by Northern hybridization. The results indicated that cDNA-AFLP was a suitable tool for studying differential expression of genie male sterility in plants. SDS-polyacrylamide gel electrophoresis patterns of soluble proteins further verified the difference in A/B lines. 展开更多

A PCR-based homologous cloning strategy was used to identify an actin gene from the roots of Chinese licorice(Glycyrrhiza uralensis Fisch). Results of sequence analysis indicate that a 1137 bp cDNA with an open reading frame encoding 377 amino acids, actin ortholog, GuActin, was successfully cloned and characterized(GenBank accession No. EU190972). Thus far, GuActin is the first actin of Chinese licorice that has been identified at a molecular level. Analysis by Northern blot shows that GuActin was expressed strongly in the roots, particularly in radicles than in stems and leaves. These results suggest that GuActin may be a member of the vegetative subfamily of the actin family. 展开更多

Objective To explore the differential expression and mechanisms of bone formation-related genes in osteoporosis(OP)leveraging bioinformatics and machine learning methodologies;and to predict the active ingredients of targeted traditional Chinese medicine(TCM)herbs.Methods The Gene Expression Omnibus(GEO)and GeneCards databases were employed to conduct a comprehensive screening of genes and disease-associated loci pertinent to the pathogenesis of OP.The R package was utilized as the analytical tool for the identification of differentially expressed genes.Least absolute shrinkage and selection operator(LASSO)logis-tic regression analysis and support vector machine-recursive feature elimination(SVM-RFE)algorithm were employed in defining the genetic signature specific to OP.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analyses for the selected pivotal genes were conducted.The cell-type identification by estimating rela-tive subsets of RNA transcripts(CIBERSORT)algorithm was leveraged to examine the infiltra-tion patterns of immune cells;with Spearman’s rank correlation analysis utilized to assess the relationship between the expression levels of the genes and the presence of immune cells.Coremine Medical Database was used to screen out potential TCM herbs for the treatment of OP.Comparative Toxicogenomics Database(CTD)was employed for forecasting the TCM ac-tive ingredients targeting the key genes.AutoDock Vina 1.2.2 and GROMACS 2020 softwares were employed to conclude analysis results;facilitating the exploration of binding affinity and conformational dynamics between the TCM active ingredients and their biological targets.Results Ten genes were identified by intersecting the results from the GEO and GeneCards databases.Through the application of LASSO regression and SVM-RFE algorithm;four piv-otal genes were selected:coat protein(CP);kallikrein 3(KLK3);polymeraseγ(POLG);and transient receptor potential vanilloid 4(TRPV4).GO and KEGG pathway enrichment analy-ses revealed that these trait genes were predominantly engaged in the regulation of defense response activation;maintenance of cellular metal ion balance;and the production of chemokine ligand 5.These genes were notably associated with signaling pathways such as ferroptosis;porphyrin metabolism;and base excision repair.Immune infiltration analysis showed that key genes were highly correlated with immune cells.Macrophage M0;M1;M2;and resting dendritic cell were significantly different between groups;and there were signifi-cant differences between different groups(P<0.05).The interaction counts of resveratrol;curcumin;and quercetin with KLK3 were 7;3;and 2;respectively.It shows that the interac-tions of resveratrol;curcumin;and quercetin with KLK3 were substantial.Molecular docking and molecular dynamics simulations further confirmed the robust binding affinity of these bioactive compounds to the target genes.Conclusion Pivotal genes including CP;KLK3;POLG;and TRPV4;exhibited commendable significant prognostic value;and played a crucial role in the diagnostic assessment of OP.Resveratrol;curcumin;and quercetin;natural compounds found in TCM;showed promise in their potential to effectively modulate the bone-forming gene KLK3.This study provides a sci-entific basis for the interpretation of the pathogenesis of OP and the development of clinical drugs. 展开更多

As typical visual culture symbol of China, the visual image of Sun Wukong firstly appeared on the mural of Yulin Caves of Dunhuang in Western Xia regime and the story of Monk Tang and his prentices on the mural in Yuan Dynasty. Up to Yuan Dynasty, it became very popular. Since the novel Pilgrimage to the West was published, the visual image of Sun Wukong has appeared in the visual carriers of wood block, colored drawing, paper-cut, traditional Chinese opera, film, television, ad, cartoon and so on. European countries, America, Japan and South Korea use advanced film and TV technology and digital technology to deduce, model, adapt and simulate the visual image of Sun Wukong. This paper investigates the construction of the visual image of Sun Wukong in China and extraterritorial countries and regions, tries to explore Chinese "visual" experience in mediaeval times and especially modern times and seeks a clue for understanding Chinese problem of visual expression. 展开更多

The exocyst is a conserved protein complex,and required for vesicles tethering,fusion and polarized exocytosis.Exo70A1,the exocyst subunit,is essential for assembly of the exocyst complex.To better understand potential roles of Exo70A1 in non-heading Chinese cabbage(Brassica campestris ssp.chinensis),we obtained the full-length cDNA of Exo70A1 gene,which consisted of 1 917 bp and encoded a protein of 638 amino acids.BlastX showed BcExo70A1 shared 94.9% identity with Brassica oleracea var.acephala(AEI26267.1),and clustered into a same group with other homologues in B.oleracea var.acephala and Brassica napus.Subcellular localization analysis showed BcExo70A1 was localized to punctate structures in cytosol of onion epithelial cells.Results showed that BcExo70A1 was widely presented in stamens,young stems,petals,unpollinated pistils,roots and leaves of self compatible and incompatible plants.The transcripts of BcExo70A1 in non- heading Chinese cabbage declined during initial 1.5 h after incompatible pollination,while an opposite trend was presented after compatible pollination.Our study reveals that BcExo70A1 could play essential roles in plant growth and development,and is related to the rejection of self pollen in non-heading Chinese cabbage. 展开更多

The expression of traditional Chinese literati is based on connection, seeking emotion and harmony. With various forms, though, this style of expression shares the same value in some art forms, like traditional Chinese poetry, calligraphy and paintings, and Chinese architecture. Based on the commonalities of various forms of literature and art, this paper offered an insight into Chinese architecture in light of poetic and pictorial expression of traditional Chinese literati. In order to illuminate the corresponding connection between traditional Chinese poetry, calligraphy and paintings, and Chinese architecture, this paper discussed the expression of Chinese architecture corresponding to the essence of traditional Chinese poetry, calligraphy and paintings respectively from the perspective of philosophy, aesthetics, and culture study of Chinese architecture. Via analogous analysis, which includes the analogy between the emotion of architecture and the feelings in traditional poetry, the analogy between the order of architecture and the spirit of calligraphy, and the analogy between the artistic conception and the picturesque scene, the poetic and pictorial expression of Chinese architecture was clarified. This paper emphasized that Chinese architecture needs to jump out of the concrete image, eradicate the interdisciplinary boundaries, and stress the integration of arts and humanities in a higher level, to express Chinese architecture in a Chinese way. That means making Chinese architecture modern in forms and techniques, and traditional in spirit and artistic conception. 展开更多
