ObjectiveTo analyze the expression of molecular marker affecting the prognosis of acute myeloid leukemia (AML) patients from bioinformatics database, thus providing an experimental basis for further exploration of a novel molecular marker for the prognosis of AML. MethodsThe prognostic data of 179 AML patients from The Cancer Genome Atlas (TCGA) database were examined for differential gene analysis and survival analysis. The bone marrow samples of 74 healthy individuals (HI) and 542 de novo AML patients in the dataset GSE13159 downloaded from the Gene Expression Omnibus (GEO) database were analyzed to detect the difference in the expression levels of differential target genes. Peripheral blood and bone marrow samples were collected from 18 de novo AML patients and 20 age- and gender-matched healthy controls, and real-time fluorescent quantitative PCR was used to validate the expression levels of the differential genes in the AML patients. ResultsBioinformatics data analysis showed that the optimal cut-off value of Homo sapiens NK2 homeobox 3 (NKX2-3) calculated by R language was 0.051. Survival analysis revealed a statistically poorer overall survival in de novo AML patients with high NKX2-3 expression than in those with low NKX2-3 expression (P = 0.0036). NKX2-3 was highly expressed in patients with de novo AML than in HI and the difference was statistically significant (P < 0.001). Real-time fluorescence quantitative PCR verified the expression levels of the NKX2-3 gene in AML patients and confirmed that compared with those in HI, in the de novo AML patients, NKX2-3-1 and NKX2-3-2 were highly expressed and were significantly correlated (P = 0.000, P = 0.000). ConclusionNKX2-3 is highly expressed in de novo AML patients, and the AML patients with high NKX2-3 expression have poor overal survival. NKX2-3 may be closely related to the clinical outcome and prognosis of AML.

The banana Fusarium wilt (BFW) caused by Fusarium oxysporum f. sp. cubense tropical race4 (FocTR4) is difficult to control worldwide, which causes a huge economic losse to banana industry. The purpose of this study was to screen Trichoderma strains with antagonistic activity against FocTR4, to isolate and purify the active compound from the fermentation broth, so as to provide important biocontrol strains and active compound resources. In this work, Trichoderma strains were isolated and screened from the rhizosphere soil of crops, and the strains capable of efficiently inhibiting FocTR4 were screened by plate confrontation, and further confirmed by testing inhibition for the conidial germination and mycelial growth of FocTR4. The phylogenetic tree clarified the taxonomic status of the biocontrol strains. Moreover, the active components in the fermentation broth of the strains were separated and purified by column chromatography, the structure of the most active component was analyzed by nuclear magnetic resonance spectroscopy (NMR), the BFW control effect was tested by pot experiments. We obtained a strain JSHA-CD-1003 with antagonistic activity against FocTR4, and the inhibition rate from plate confrontation was 60.6%. The fermentation broth of JSHA-CD-1003 completely inhibited the germination of FocTR4 conidia within 24 hours. The inhibition rate of FocTR4 hyphae growth was 52.6% within 7 d. A phylogenetic tree was constructed based on the ITS and tef1-α gene tandem sequences, and JSHA-CD-1003 was identified as Trichoderma brevicompactum. Purification and NMR identification showed that the single active compound was trichodermin, and the minimum inhibitory concentration (MIC) was 25 μg/mL. Pot experiments showed that the fermentation broth of strain JSHA-CD-1003 was effective against BFW. The control rate of leaf yellowing was 47.4%, and the rate of bulb browning was 52.0%. Therefore, JSHA-CD-1003 effectively inhibited FocTR4 conidial germination and mycelium growth through producing trichodermin, and showed biocontrol effect on banana wilt caused by FocTR4, thus is a potential biocontrol strain.

Objective:To observe and evaluate the clinical efficacy and safety of albumin-bound paclitaxel as first-line treatment for patients with advanced pancreatic cancer in China, and to explore the prognosis-related molecules in pancreatic cancer based on next-generation sequencing (NGS) of tumor tissues.Methods:From December 2018 to December 2020, patients with locally advanced or metastatic pancreatic cancer were recruited to accept albumin-bound paclitaxel as first-line treatment in the oncology departments of 24 hospitals in East China. The primary endpoints were overall survival (OS) and treatment related adverse events, and the secondary endpoint was progression-free survival (PFS). Adverse effects were graded using Common Terminology Criteria for Adverse Events 5.0 (CTCAE 5.0). NGS sequencing on the primary or metastatic tissue samples of pancreatic cancer obtained through surgical resection or biopsy was performed.Results:This study recruited 229 patients, including 70 patients with locally advanced pancreatic cancer (LAPC) and 159 patients with metastatic pancreatic cancer (mPC). The disease control rate was 79.9% and the objective response rate is 36.3%.The common adverse effects during treatment were anaemia (159 cases), leucopenia (170 cases), neutropenia (169 cases), increased aminotransferases (110 cases), and thrombocytopenia (95 cases), and the incidence of grade 3-4 neutropenia is 12.2% (28/229). The median follow-up time was 21.2 months (95% CI: 18.5-23.1 months). The median PFS (mPFS) was 5.3 months (95% CI: 4.37-4.07 months) and the median OS (mOS) was 11.2 months (95% CI: 9.5-12.9 months). The mPFS of patients with LAPC was 7.4 months (95% CI: 6.6-11.2 months), and their mOS was 15.5 months (95% CI: 12.6-NA months). The mPFS of patients with mPC was 3.9 months (95% CI: 3.4-5.1 months), and their mOS was 9.3 months (95% CI: 8.0-10.8 months). Multivariate Cox regression analysis showed that clinical stage ( HR=1.47, 95% CI: 1.06-2.04), primary tumor site ( HR=0.64, 95% CI: 0.48-0.86), Eastern Cooperative Oncology Group Performance Status (ECOG PS) score ( HR=2.66, 95% CI: 1.53-4.65), and whether to combine radiotherapy ( HR=0.65, 95% CI: 0.42-1.00) were independent influencing factors for the PFS of these patients. The primary tumor site ( HR=0.68, 95% CI: 0.48-0.95), ECOG score ( HR=5.82, 95% CI: 3.14-10.82), and whether to combine radiotherapy ( HR=0.58, 95% CI: 0.35-0.96) were independent influencing factors of the OS of these patients. The most frequent gene mutations in these advanced stage pancreatic patients were KRAS (89.66%), TP53 (77.01%), CDKN2A (32.18%), and SMAD4 (21.84%) by NGS of tumor tissues from 87 pancreatic cancer patients with sufficient specimens. Further analysis revealed that mutations in CDKN2B, PTEN, FGF6, and RBBP8 genes were significantly associated with an increased risk of death ( P<0.05). Conclusion:Albumin-bound paclitaxel as first-line treatment demonstrated feasible anti-tumor efficacy and manageable safety for patients with advanced pancreatic cancer in China.

Chronic atrophic gastritis(CAG)is a common intractable gastric disease in clinic,which belongs to the gastric precancerous lesions.Professor LIU Feng-Bin and his team have performed the exploration and practice in the field of CAG for more than 30 years,and they proposed that the evolution of the traditional Chinse medicine(TCM)pathogenesis of inflammation-to-tumor transition(ITT)in CAG was characterized by spleen deficiency being the root cause,qi stagnation,blood stasis and dampness retention being the branch cause,and stasis and toxin being the aggravating factors.Deificiency of the spleen and stomach is the initial factor of CAG,which influences the whole process of the disease.Qi stagnation,blood stasis and dampness retention are the triggering and aggravating factors for the ITT in CAG.The formation of blood stasis and toxin is the key to the progression and transition of CAG.Treatment of ITT in CAG should be based on the results of syndrome differentiation and gastroscopic findings by staging therapy.Before treatment,disease dianosis and syndrome differentiation should be made,and macro and micro syndrome differentiation should be carried out for assistance.Therapy of strengthening the spleen and supporting healthy qi should be implemented throughout the whole process of the disease.The early stage of CAG has the features of gastric mucosa with mild to moderate atrophy and with or without mild intestinal epithelial hyperplasia,the pathogenesis of early CAG is characterized by weakness of the spleen and stomach and is accompanied with the pathological factors of qi stagnation,damp-retention and blood stasis,and the basic treatment should adopt the therapies of strengthening the spleen and clearing heat,regulating qi and activating blood stasis.The advanced stage of CAG has the features of severe atrophic gastric mucosa with or without moderate to severe intestinal epithelial and/or mild to moderate intraepithelial neoplasia,the pathogenesis is characterized by weakness of the spleen and stomach,phlegm blended with blood stasis,and stasis-toxin in the gastric collaterals,and the basic treatment should adopt the therapies of supporting healthy qi and dissipating masses,and unblocking the collaterals and removing toxin,so as to construct an intact line to blocking the ITT in CAG with traditional Chinese medicine.

Recent studies have shown that stress can substantially facilitate breast cancer metastasis,which can be reduced by nonselective β1/β2-adrenergic receptor(β1/β2-AR)blocker.However,several side effects were identified.Thus,it is extremely warranted to explore more effective and better-tolerated β2-AR blocker.Currently,we demonstrated that baicalin(BA),a major bioactive component of Scutellaria bai-calensis Georgi,could significantly attenuate stress hormones especially epinephrine(Epi)-induced breast cancer cell migration and invasion in vitro.Mechanistically,we identified that β2-AR was a direct target of BA via the drug affinity responsive target stability(DARTS)combined with mass spectrum assay,and BA photoaffinity probe with pull-down assay,which was further confirmed by a couple of bio-physical and biochemical assays.Furthermore,we demonstrated that BA could directly bind to the Phe-193 and Phe-289 of β2-AR,subsequently inhibit cyclic adenosine monophosphate-protein kinase A-focal adhesion kinase(cAMP-PKA-FAK)pathway,and thus impede epithelial-mesenchymal transition(EMT),thereby hindering the metastatic progression of the chronic stress coupled with syngeneic and xenograft in vivo orthotopic and tail vein mouse model.These findings firstly identify BA as a potential β2-AR inhibitor in the treatment of stress-induced breast cancer metastasis.
