First Report of Fusarium acuminatum Causing Leaf Spot on Schisandra chinensis in China.

Schisandra chinensis (Turcz.) Baill. is a popular and widely cultivated medicinal herb in China, which has rich nutritional value and medicinal effect. In August 2022, leaves with oval and irregularly circular light brown spots from 2 to 10 mm wide with white centers were found on Schisandra chinensis growing in Fusong district (127°28'E, 42°33'N) of Jilin, China. The symptoms were observed in 20% of the plants of a 2 ha-1 field of Schisandra chinensis. About 50% of the leaf areas were affected. As the disease developed, the lesions grew larger and developed necrotic centers. Leaves with light brown spot symptoms from five plants were collected from the field. Five leaf pieces (3 to 5 mm2) were excised from lesion margins, surface sterilized based on Ju et al. (Ju et al. 2021), and incubated on potato dextrose agar (PDA) at 25°C. Six single spores were isolated from five independently infected isolates for pure culture using the single spore isolation technique (Zhang. 2003). Representative single spore isolate (ZWWZH) was selected from pure cultures for further culture. After 5 days, fluffy white aerial mycelium with pink pigmentation on the underside of the colony were observed on PDA. Mycelia became pinkish-brown as the culture aged. Microscopic observations showed the presence of elongated or pointed, and thick-walled macroconidia (n = 50), predominantly three septate, 3.40 to 7.50 × 40.34 to 61.29 µm were observed. Chlamydospores formed in chains within or on top of the mycelium. The primers ITS1/ITS4 (White et al. 1990) and Bt-2a/Bt-2b (Robideau et al., 2011) were used to amplify the internal transcribed spacer (ITS) rDNA and ß-tubulin (TUB2) region, respectively. The obtained sequences were submitted to GenBank under accession numbers for OQ629789 (ITS) and OQ803521(TUB2). BLASTn analysis of both ITS sequence and TUB2 sequence, revealed 100% and 99.92% sequence identity with F. acuminatum MT566456, MT560377 and KJ396328, respectively. The pathogen was identified as F. acuminatum based on morphological and molecular data. Pathogenicity tests were carried out in the greenhouse. Select five healthy Schisandra chinensis seedlings, each with each healthy leaf surfaces inoculated a 1 × 106 spores/mL solution, 3 wells on one side, 10 µL per well. Sterile ddH2O was used in the control experiment. The inoculated seedlings were incubated at 25°C with a relative humidity of 65 to 70% in a greenhouse. Four days after inoculation, all inoculated leaves exhibited the same symptoms as observed in the field, while the controls showed no symptoms. The experiment was repeated three more times with similar results. The re-isolated fungi from the inoculated plants had the same morphology and DNA sequences as the original isolate (ZWWZH) obtained from the field samples, completing Koch's postulates. To our knowledge, this is the first report of F. acuminatum causing leaf spot on Schisandra chinensis in China. F. acuminatum has seriously affected the quality of Schisandra chinensis production. The identification of leaf spot caused by F. acuminatum will enable farmers to identify practices to minimize disease on this important crop.

Reverse effect of Semaphorin-3F on rituximab resistance in diffuse large B-cell lymphoma via the Hippo pathway / 中华医学杂志(英文版)

BACKGROUND@#Exploring the underlying mechanism of rituximab resistance is critical to improve the outcomes of patients with diffuse large B-cell lymphoma (DLBCL). Here, we tried to identify the effects of the axon guidance factor semaphorin-3F (SEMA3F) on rituximab resistance as well as its therapeutic value in DLBCL.@*METHODS@#The effects of SEMA3F on the treatment response to rituximab were investigated by gain- or loss-of-function experiments. The role of the Hippo pathway in SEMA3F-mediated activity was explored. A xenograft mouse model generated by SEMA3F knockdown in cells was used to evaluate rituximab sensitivity and combined therapeutic effects. The prognostic value of SEMA3F and TAZ (WW domain-containing transcription regulator protein 1) was examined in the Gene Expression Omnibus (GEO) database and human DLBCL specimens.@*RESULTS@#We found that loss of SEMA3F was related to a poor prognosis in patients who received rituximab-based immunochemotherapy instead of chemotherapy regimen. Knockdown of SEMA3F significantly repressed the expression of CD20 and reduced the proapoptotic activity and complement-dependent cytotoxicity (CDC) activity induced by rituximab. We further demonstrated that the Hippo pathway was involved in the SEMA3F-mediated regulation of CD20. Knockdown of SEMA3F expression induced the nuclear accumulation of TAZ and inhibited CD20 transcriptional levels via direct binding of the transcription factor TEAD2 and the CD20 promoter. Moreover, in patients with DLBCL, SEMA3F expression was negatively correlated with TAZ, and patients with SEMA3F low TAZ high had a limited benefit from a rituximab-based strategy. Specifically, treatment of DLBCL cells with rituximab and a YAP/TAZ inhibitor showed promising therapeutic effects in vitro and in vivo .@*CONCLUSION@#Our study thus defined a previously unknown mechanism of SEMA3F-mediated rituximab resistance through TAZ activation in DLBCL and identified potential therapeutic targets in patients.

[Effect of Chelating Agents and Organic Acids on Remediation of Cadmium and Arsenic Complex Contaminated Soil Using Xanthium sibiricum].

In order to improve the phytoextraction efficiency of Xanthium sibiricum on farmland soil that had been contaminated by Cd and As, this study explored the effects of chelating agents and organic acids (EDTA, SAP, CA, and MA) on the extraction of Cd and As heavy metals using X. sibiricum. The results showed that the four different chelating agents and organic acids had little effect on the biomass of the roots, stems, and leaves of X. sibiricum. However, they had different effects on the concentrations and accumulation of Cd and As in various organs of X. sibiricum. Compared with the those in the CK treatment, EDTA, SAP, CA, and MA significantly increased the Cd concentrations in the leaves of X. sibiricum by 44.1%, 32.4%, 41.2%, and 38.2% and the As concentrations in the roots of X. sibiricum by 89.6%, 7.4%, 94.8%, and 61.5%, respectively. The four treatments (EDTA, SAP, CA, and MA) improved the total Cd accumulation of X. sibiricum, with increasing ranges, respectively, of 70.2%, 29.4%, 28.9%, and 33.1%, and the As accumulation increased by 67.0%, 19.6%, 81.9%, and 40.8%, respectively, compared with that of the CK treatment. The four chelating agents and organic acids had different effects on the Cd and As bioconcentration factor and transfer factor of various organs of X. sibiricum. Treatments with EDTA, SAP, CA, and MA resulted in a decrease of 32.7%-38.2% in soil Cd concentrations and a decrease of 14.6%-20.5% in soil As concentrations. These four chelating agents can be used for enhancing the efficiency of extraction Cd and As heavy metals by X. sibiricum.

Effect of matrine sodium chloride injection on a mouse model combining disease with syndrome of human coronavirus pneumonia with cold-dampness pestilence attacking the lung / 药学学报

"TCM syndrome of plague attack lung" is a classification of traditional Chinese medicine syndromes of the novel coronavirus pneumonia by the Beijing Municipal Administration of Traditional Chinese Medicine. In this study, a mouse model combining disease with syndrome of human coronavirus pneumonia with cold-dampness pestilence attacking the lung was established for the first time, and the therapeutic effect of matrine sodium chloride injection was evaluated based on immune regulation and inflammatory damage. Lung index, lung index inhibition rate and HE stain were used to evaluate the therapeutic effect of matrine sodium chloride injection on the model mice; the viral load in lung tissue was measured by RT-PCR to evaluate its antiviral effect; the percentage of CD4+ T cells, CD8+ T cells and B cells were detected by flow cytometry to evaluate its immunomodulatory effect; the production of interleukin 6 (IL-6), IL-10, tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) were measured by ELISA to evaluate its anti-inflammatory effect. All interventions and operations in the experiment were approved by the Animal Ethics Committee of the Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences, and conformed to the Guide for the Care and Use of Laboratory Animals published by the US National Institutes of Health (NIH) and Beijing Experimental Animal Ethics Committee. The results showed that intraperitoneal injection of the high-dose (36.67 mL·kg-1·d-1) and low-dose (18.33 mL·kg-1·d-1) of matrine sodium chloride injection significantly improved the pathological damage of lung tissue and reduced lung index. The lung index inhibition rates were 86.86% and 76.53%, respectively. The production of IL-6, IL-10, TNF-α, IFN-γ, as well as the viral load in lung tissue were reduced significantly compared to the model; the percentage of CD4+ T cells, CD8+ T cells and B cells in peripheral blood were increased compared to the model. These results indicated that the matrine sodium chloride injection has an evident therapeutic effect on the model, and its mechanism was related to the inhibition virus replication, regulation of immunity function and inhibition of inflammatory factor release. This study provided laboratory data support for matrine sodium chloride injection which was used to treat the novel coronavirus pneumonia in clinical in Hubei province. These results indicated that the matrine sodium chloride injection has a good prospect for prevention and treatment of the novel coronavirus pneumonia.

Clinical significance of matrix metalloproteinase 3 in different active states of rheumatoid arthritis / 中华检验医学杂志

Objective:To investigate the levels and the clinical signficance of matrix metalloproteinase 3 (MMP-3) in different activities of rheumatoid arthritis (RA).Methods:Case-control study. A total of 130 patients [24 cases of male, 106 cases of female, age (52.98±13.24)years, the median age was 51 years] with RA diagnosed in the Department of Rheumatology from the Second Affiliated Hospital of Soochow University, Suzhou Hospital of Traditional Chinese Medicine and Suzhou Ninth People′s Hospital from 2017 to 2018, and 100 healthy controls [28 cases of male, 72 cases of female, age (45.04±11.55) years, the median age was 44 years] from the physical examination center of the Suzhou Ninth People′s Hospital. The basic clinical data was used to determine the MMP-3 on groups of RA patients and healthy controls by immunoturbidimetry. The discriminating validity of MMP-3 in disease was evaluated using receiver operating characteristic (ROC) curve analysis.Results:Compared with that in healthy controls[28.0 (21.7-36.1)ng/mL], the MMP-3 in the low groups [51.8(41.8-73.1)ng/mL] increased dramatically ( Z=2.942, P<0.01). However, there was no significant difference between the MMP-3 in remission patients [28.8 (21.9-38.7)ng/mL] compared with the healthy controls ( Z=1.09, P>0.05). The area under the curve (AUC) of MMP-3 for diagnosis of RA was 0.877. the sensitivity was 73.1%, and the specificity was 93%.The AUC of MMP-3 diagnosis of low groups was 0.906, the sensitivity was 77.8%, and the specificity was 88%. In addition, the MMP-3 level was correlated with CRP and ESR ( r=0.242, r=0.243), and it was significantly correlated with DAS 28 ( r=0.361). Conclusions:It was indicated that the level of MMP-3 increased with the severity of rheumatoid arthritis. And the clinically low level of MMP-3 in RA patients could be used to indicate the remission condition. Meanwhile, the serum MMP-3 was closely related to DAS28.
