This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). This article has been retracted at the request of the Editors-in-Chief. A large part of the article is highly similar to the paper previously published by Wenqian Hou, Lei Ren, Yang Zhang, Haoyun Sun, Tianye Shi, Yulan Gu, Aimin Wang, Daifu Ma, Zongyun Li and Lei Zhang in Scientia Horticulturae 288 (2021) 110374 https://doi.org/10.1016/j.scienta.2021.110374. In particular, a large part of the two articles shows a study on the same gene family in the same plant, with similar methodological approaches, resulting in a series of highly similar figures. One of the conditions of submission of a paper for publication is that authors declare explicitly that their work is original and has not appeared in a publication elsewhere. Re-use of any data should be appropriately cited. As such this article represents a severe abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the submission process.

Effects of imidapril on blood gas, oxidative stress and inflammatory fac-tors in rats with acute lung injury induced by ammonium chloride / 中国病理生理杂志

AIM:In this study, the rat lung injury model was induced by ammonium chloride for studying the effect of imidapril on blood gas, serum TNF-α, IL-6 and MDA concentrations, and AngⅡand CD54 protein expression in rat lung tissue.METHODS:Male rats were randomly divided into 3 groups:control group, lung injury model group and drug group.The rats in control group were given saline (2 mL/kg), while the rats in lung injury model group were given 6% ammonium chloride (2 mL/kg).In drug group, imidapril (3 mg· kg-1· d-1) was given to the rats once daily for 1 week by intragastric gavage after given 6%ammonium chloride.On the 7th day, the rats were anesthetized with 2% so-dium pentobarbital.Abdominal aorta blood, venous blood and lung tissue were collected.The blood gas indexes and serum TNF-α, IL-6 and MDA concentrations were determined.The lung tissues were fixed and sliced, and the expression of AngⅡ and CD54 proteins was detected by immunohistochemistry.RESULTS: The PaCO2 increased in lung injury model group compared with control group and drug group (P<0.05).The expression of AngⅡand CD54, and the concentrations of TNF-α, IL-6 and MDA also increased significantly ( P<0.01) in model group.Pulmonary edema, inflammation, alveo-lus congestion, hemorrhage and hyperplasia in model group were obvious compared with control group and drug group. CONCLUSION:Imidapril improves blood gas indexes, and reduces lipid peroxidation and inflammatory responses in the rats with lung injury induced by ammonium chloride.

F-01A, an antibiotic, inhibits lung cancer cells proliferation / 中国天然药物

AIM@#In an effort to identify novel, small molecules which can affect the proliferation of lung cancer cells, F-01A, a polyether antibiotic isolated from the fermentation broth of Streptomyces was tested.@*METHOD@#F-01A was tested for its antitumor properties on the lung cancer cell line SPC-A-1, at six doses (0.1, 0.5, 1, 2.5, and 5 μmol·L(-1)), using various cellular assays. Cell viability was measured by the MTT assay, Hochest 33258 was used to study nuclear morphology; DNA ladder and the loss of mitochondrial membrane potential were also evaluated.@*RESULTS@#F-01A induces apoptosis against SPC-A-1 cells in a dose-dependent manner. The IC50 is 0.65 μmol·L(-1), and the inhibition at 5 μmol·L(-1) is 87.89%. Further, JC-1 staining indicates F-01A could induce the loss of mitochondrial membrane potential, and the DNA fragment is evident.@*CONCLUSION@#Mechanistic analysis showed that F-01A induced apoptosis of cancer cells probably in the mitochondrial pathway. The antitumor actions of F-01A involve activation of the apoptotic pathway against SPC-A-1 cells, and it may be valuable for further drug development.

Social Network Analysis of the Co-authoring Network in Domestic International Classification of Diseases Field / 中华医学科研管理杂志

Objective The purpose of this article is to analyze the domestic situation of co-authorship in the field of international classification of diseases using Social Network Analysis.Methods Using UCINET to do this research from the following five perspectives,namely density,degree centrality,betweenness centrality,closeness and subgroup analysis.Results The density of co-authoring network is 0.0021.The number of nodes which made up the main component accounts for 3.46％ of the total nodes.Lin Jie-zhong possesses the highest value of degree centrality,and Guo Yun-qing's value of betweenness centrality and closeness is the highest.Forty-four 2-plexes are found in all authors.Conclusions Currently,the co-authorship is not close,but to a certain extent,the authors liked Lin Jie-zhong,Liang Yao,Li Jian-wei,Fan Wei,Guo Yun-qing,Liu Ai-min and so on constitute the core members or leaders.From the overall point of view,the authors in this field have not yet formed a subgroup phenomenon obviously.The structure of this co-authoring network is loose and isolated.

Susceptibility to hepatocellular carcinoma associated with null genotypes of GSTM1 and GSTT1.

AIM:In order to study the association between the null genotypes of GSTM1 and GSTT1 and the genetic susceptibility to hepatocellular carcinoma (HCC).METHODS:The genotypes of GSTM1 and GSTT1 of 63 cases of HCC and 88 controls were detected with the multiple PCR technique.RESULTS:The frequency of GSTM1 null genotype was 57.1% among the cases, and 42.0% among the controls, the difference being statistically significant (X(2) = 3.35, P = 0.067), but X(2) value approaching the significance level. The odds ratio was 1.84 (95% CI = 0.91-3.37). The frequency of GSTT1 non-null genotype was 87.3% among the cases and 62.5% among the controls, the difference being statistically significant (X(2) = 11.42, P = 0.0007274). The odds ratio was 4.13 (95% CI = 1.64-10.70).According to the cross analysis, the GSTT1 non null genotype was more closely associated with HCC than GSTM1 null genotype, and these two factors play an approximate additive interaction in the occurrence of HCC.CONCLUSION:The persons with GSTM1 null genotype and GSTT1 non-null genotype have the increased risk to HCC.
