Biocontrol effects of Penicillium griseofulvum against monkshood (Aconitum carmichaelii Debx.) root diseases caused by Sclerotium rolfsiii and Fusarium spp. J Appl Microbiol 2019; 127:1532-1545. [PMID: 31304623 DOI: 10.1111/jam.14382] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2019] [Revised: 06/26/2019] [Accepted: 07/02/2019] [Indexed: 12/29/2022]
Abstract
AIMS The aims of this study were to investigate the biocontrol effects of Penicillium griseofulvum strain CF3 and its mechanisms against soil-borne root pathogens (Fusarium oxysporum and Sclerotium rolfsii) of the medical plant Aconitum carmichaelii Debx. METHODS AND RESULTS The effects of P. griseofulvum strain CF3 were evaluated with regard to the hyphal growth of S. rolfsii and F. oxysporum, the sclerotial formation and germination of S. rolfsii and its expression of sclerotia-formation-related genes. A field experiment was conducted to explore how strain CF3 controls the severity of soil-borne diseases, promotes the growth of A. carmichaelii plants and mediates shifts in the culturable rhizosphere microbial populations. The results showed that treatment with a cell-free culture filtrate of strain CF3 considerably inhibited the hyphal growth of both S. rolfsii and F. oxysporum, in addition to limiting the sclerotial formation and germination of S. rolfsii. Three genes related to sclerotial formation (ArsclR, ArnsdD1 and ArnsdD2) were predicted in S. rolfsii and their expression was found suppressed by the CF3 treatment. Field application of the CF3 biocontrol agent in a powder form (1·9 × 1010 conidia per gram of substrate) reduced soil-borne disease severity by 15·0%. The shoot and root growth of A. carmichaelii plants was promoted by 61·6 and 83·1% respectively, as the biocontrol strain massively colonized the rhizosphere soil. The CF3 treatment also markedly reduced the density of some known species harmful to plants while increasing the density of some beneficial species in the rhizosphere soil. SIGNIFICANCE AND IMPACT OF THE STUDY Genes related to sclerotia formation of S. rolfsii are predicted for the first time and their expression patterns in the presence of P. griseofulvum strain CF3 are evaluated. This comprehensive study provides a candidate fungal biocontrol strain and reveals its potential mechanisms against S. rolfsii and F. oxysporum in A. carmichaelii plants.

Abstract
Objective: To compare the expression of leukemia inhibitory factor (LIF), interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF) in tissue and fluid samples from patients with endometriosis, and investigate whether LIF and IL-6 regulate VEGF in human endometriotic stromal cells (ESC). Methods: The levels of VEGF, LIF, IL-6 in serum, peritoneal fluid of patients with and without endometriosis were measured by ELISA. The mRNA of these three factors in the ectopic and eutopic endometrial tissue and stromal cells were measured by real-time PCR. ESC derived from ovarian endometriomas were cultured using the method of primary cell culture with LIF and IL-6, and the level of VEGF mRNA and protein were measured by the method of real-time PCR and ELISA respectively. Results: VEGF and IL-6 concentration were 1.2 and 1.3 times higher in the serum of patients with endometriosis than in the control group [(94±19) versus (78±17) ng/L; (45±14) versus (35±9) ng/L; all P<0.05]. VEGF and IL-6 concentration were 1.2 and 1.4 times higher in the peritoneal fluid of patients with endometriosis than in the control group [(110±25) versus (91±21) ng/L; (69±20) versus (49±15) ng/L; all P<0.05]. VEGF and IL-6 concentrations in peritoneal fluid of patients with endometriosis were 1.2 and 1.5 times higher than in serum (all P<0.01). VEGF, LIF and IL-6 mRNA expression were 2.2, 8.6, 44.7 times higher in ESC compared with the matching eutopic endometrial stromal cells (all P<0.01). LIF and IL-6 mRNA were 2.0 and 64.8 times higher in ectopic endometrial tissue than the matching eutopic endometrial tissue (all P<0.05).ESC cultured with LIF, IL-6 and LIF+IL-6 induce VEGF protein secretion [(106±18), (124±30), (140±27) ng/L] by 1.3, 1.5 and 1.7 times (all P<0.05). Conclusion: Overexpression of LIF and IL-6 may synergistically contribute to upregulation of VEGF in ESC and promote development of endometriosis.

Abstract
Objective: To elucidate whether metformin could regulate the mRNA expression level of estrogen synthetase and ER in human uterine leiomyoma tissues. Methods: (1) Seventeen pairs of uterine leiomyoma tissues and adjacent myometrium (>2 cm) were collected from patients underwent hysterectomy in Peking University First Hospital between December 2016 and January 2017. Real-time PCR was used to measure the mRNA expression level of estrogen synthetase [including cytochrome P450 cholesterol side chain cleavage enzyme (P450scc), cytochrome P450 17α-hydroxylase (P450c17), 3-beta-hydroxysteroid dehydrogenase type 2 (3β-HSD-2), 17-beta-hydroxysteroid dehydrogenase type 1 (17β-HSD-1) and aromatase cytochrome P450 (P450arom)] and ER (including ERα and ERβ) in the uterine leiomyoma tissues and adjacent myometrium. (2) Uterine leiomyoma cells derived from uterine leiomyoma tissues were identified by immunocytochemistry method and cultured to the third generation. The treatment groups were cultured with different concentrations of metformin (10, 50 and 100 μmol/L) for 48 hours, and the control group was cultured with deionized water for 48 hours. The mRNA expression level of estrogen synthetase and estrogen receptor subtypes were measured by real-time PCR. Results: (1) P450scc, P450c17, 3β-HSD-2, 17β-HSD-1, P450arom mRNA median expression levels were 112, 4, 13, 42 and 194 in the uterine leiomyoma tissues, and were respectively 114, 5, 11, 32 and 6 in the myometrium. Compared to those of the myometrium, 3β-HSD-2 and P450arom mRNA expression levels in the uterine leiomyoma tissue were significantly higher (P<0.05), while there were no significant change of mRNA expression levels among P450scc, P450c17 and 17β-HSD-1 (P>0.05). ERα and ERβ mRNA median expression levels were 208 and 116 in the uterine leiomyoma tissues, and were 24 and 95 in the myometrium. Compared to that of the myometrium, ERα mRNA level in the uterine leiomyoma tissue was significantly higher (P=0.001), while there were no significant change of ERβ mRNA level (P=0.193). (2) After cultured with different concentrations of metformin (10, 50 and 100 μmol/L), the P450arom mRNA levels in the uterine leiomyoma tissues were 9±4, 8±5 and 8±3 respectively in the treatment groups and was 16±5 in the control group. Compared to that of the control group, P450arom mRNA expression levels in the treatment groups were significantly declined (P<0.05). There were no significant different change of mRNA expression levels among 3β-HSD-2, ERα and ERβ between the treatment groups and the control group (P>0.05). Conclusions: Metformin could down-regulate the mRNA expression level of aromatase in the uterine leiomyoma cells. These results indicate that metformin may inhibit the local estrogen synthesis and therefore suppress the development of uterine leiomyoma.

Abstract
Objective: The role of planned neoadjuvant radiotherapy or chemoradiotherapy in the non-radical resection of esophageal squamous cell carcinoma was unclear. The study aimed to evaluate their therapeutic effect and analyze the prognostic factors. Methods: We retrospectively analyzed the clinical data of locally advanced esophageal squamous cell carcinoma who received neoadjuvant radio therapy (33 patients) and concurrent chemoradiotherapy (119 patients) from January 2004 to December 2016 in our single-institution database.The survival rates were calculated by Kaplan-Meier method. The prognostic factors were analyzed by using Log rank test and Cox proportional hazards model. Results: The median follow-up was 29.8 months. One hundred and one patients survived more than 3 years. The rates of overall survival (OS) and disease-free survival (DFS) at 3 years were 63.9% and 55.6%, respectively.The rates of complete, partial and minimal pathological response of the primary tumor were 50.3%, 38.4%, 11.3%, the corresponding 3-year OS were 75.5%, 57.4%, 27.3% (P<0.001) and 3-year DFS were 72.0%, 44.7%, 17.6% (P<0.001), respectively.The postoperative lymph node metastasis rate was 27.0%. The 3-year OS and DFS of the lymph node positive group was 45.6% and 32.8%, significantly lower than 70.8% and 63.7% of the negative group (both P<0.001). The 3-year OS and DFS of pathologic stage Ⅰ, Ⅱ, ⅢA, ⅢB and Ⅵ A were 76.2%, 57.4%, 64.7%, 35.0%, 33.3% (P<0.001) and 70.1%, 49.3%, 41.2%, 22.1%, 33.3% (P<0.001), respectively.The operation-related mortality was 3.3%. Multivariate analysis showed that chest pain, postoperative respiratory failure, pathological differentiation, more than 15 lymph node dissection and ypTNM stage were the independent prognostic factors of OS (P<0.05 for all). Conclusions: The planned neoadjuvant radiotherapy or chemoradiotherapy for the non-radical resection of advanced esophageal squamous cell carcinoma could result in favorable survival. The chest pain, postoperative respiratory failure, pathological differentiation, the number of lymph node resection and ypTNM stage are the independent prognostic factors of the prognosis of these patients.

Abstract
BACKGROUND AND OBJECTIVE The underlying molecular mechanisms of gastric cancer (GC) have yet not been investigated clearly. In this study, we aimed to identify hub genes involved in the pathogenesis and prognosis of GC. METHODS We integrated five microarray datasets from Gene Expression Omnibus (GEO) database. The differentially expressed genes (DEGs) between GC and normal samples were analyzed with limma package. Gene ontology (GO) and KEGG enrichment analysis were performed using DAVID. Then we established the protein-protein interaction (PPI) network of DEGs by the Search Tool for the Retrieval of Interacting Genes database (STRING). The prognostic analysis of hub genes were performed through Gene Expression Profiling Interactive Analysis (GEPIA). Additionally, we used real-time quantitative PCR to validate the expression of hub genes in 5 pairs of tumor tissues and corresponding adjacent tissues. Finally, the candidate small molecules as potential drugs to treat GC were predicted in CMap database. RESULTS Through integrating five microarray datasets, a total of 172 overlap DEGs were detected including 79 up-regulated and 93 down-regulated genes. Biological process analysis of functional enrichment showed these DEGs were mainly enriched in digestion, collagen fibril organization and cell adhesion. Signaling pathway analysis indicated that these DEGs played an vital in ECM-receptor interaction, focal adhesion and metabolism of xenobiotics by cytochrome P450. Protein-protein interaction network among the overlap DEGs was established with 124 nodes and 365 interactions. Three DEGs with high degree of connectivity (NID2, COL4A1 and COL4A2) were selected as hub genes. The GEPIA database confirmed that overexpression levels of hub genes were significantly associated with worse survival of patients. Finally, the 20 most significant small molecules were obtained based on CMap database and spiradoline was the most promising small molecule to reverse the GC gene expression. CONCLUSIONS Our results indicated that NID2, COL4A1 and COL4A2 could be the potential novel biomarkers for GC diagnosis prognosis and the promising therapeutic targets. The present study may be crucial to understanding the molecular mechanism of GC initiation and progression.

Oncoimmunology 2019; 8:e1568810. [PMID: 30906662 DOI: 10.1080/2162402x.2019.1568810] [Citation(s) in RCA: 30] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2018] [Revised: 12/20/2018] [Accepted: 01/03/2019] [Indexed: 12/14/2022] Open
Abstract
Background: Although immunosenescence-induced difference on overall immune function and immune cell subsets between younger and older populations has been well characterized, the potential effect of patients' age on the efficacy of immune checkpoint inhibitors (ICIs) remains little known. We performed a meta-analysis to investigate whether age differences play a role in cancer immunotherapy efficacy based on a large amount of clinical data. Methods: We conducted a systematic search of PubMed, Embase and MEDLINE for relevant randomized controlled trials. The primary outcome was overall survival (OS) and progression-free survival (PFS) was secondary outcome. The interaction test was used to assess the heterogeneity of HR between younger and older groups. Results: In total, 19 clinical randomized trials involving 11157 patients were included. The pooled HR for OS was 0.73 (95% CI 0.69-0.78) and 0.63 (95% CI 0.52-0.73) for PFS in younger patients receiving ICIs treatments, when compared with younger patients treated with controls. For older patients treated with ICIs, the pooled HR for OS compared with controls was 0.64 (95% CI 0.59-0.69) and 0.66 (95% CI 0.58-0.74) for PFS. The difference on OS efficacy between younger and older patients treated with ICIs was significant (Pheterogeneity = 0.025). Conclusions: Immune checkpoint inhibitors significantly improved OS and PFS in both younger and older patients compared with controls, but the magnitude of benefit was clinically age-dependent. Patients ≥65 y can benefit more from immunotherapy than younger patients. Future research should take age difference into consideration in trials and focus on tolerance and toxicity of ICIs in older patients.

Abstract
Objective: Adenosquamous carcinoma of lung is an uncommon subtype with more aggressive behavior and poor prognosis than adenocarcinoma and squamous cell carcinoma. This study was aimed to investigate the clinicopathological characteristics and prognostic factors of lung adenosquamous carcinoma. Methods: The pathological features and follow-up data of 133 patients were collected and the prognostic factors of these patients were retrospectively analyzed. Results: Among the 133 patients, 81 cases (60.9%) smoked. Among the 62 patients whose percentage of histological components were identified, 45 cases had >50% adenocarcinoma components, and 17 cases had >50% squamous cell carcinoma components. 55 patients had lymph node metastasis at the first visit. All patients accepted at least one test of tumor driven gene mutation, and the results showed that the mutation rate of EGFR was 50.8% (67/132), the mutation rate of K-ras was 8.6% (11/128), the ALK-positive rate was 4.2% (2/48). The gender, smoking status, and the proportion of pathological components were the main influence factors of EGFR mutation status. The median overall survival was 28 months, the rates of 1-year, 3-year, and 5-year survival were 72.9%, 23.3%, and 9.0%, respectively. EGFR tyrosine kinase inhibitors (TKIs) treatment was an independent risk factor for prognose of these patients (P=0.024). Conclusions: Lung adenosquamous carcinoma is a rare subtype with high malignancy and poor prognosis. Early diagnosis and driven-mutation-based individualized therapy may improve the survival of patients with lung adenosquamous carcinoma.

Abstract
Cerebrovascular diseases have a heavy burden on society and the family. At present, in the treatment of cerebrovascular diseases, the recognized effective treatment method is a thrombolytic therapy after cerebral infarction, but limited to the time window problem, many patients cannot benefit. Other treatments for cerebrovascular disease are still in the exploration stage. The study found that medical gas and hypothermia have brain protection effects. Further research found that when the two are used in combination, the therapeutic effect has a superimposed effect. This article reviews the current research progress of hypothermia therapy combined with medical gas therapy for cerebrovascular disease.

Abstract
The C-terminal binding protein 2 (CtBP2) is crucial for the activation of the Wnt/β-catenin pathway and regulates significant cellular processes in multiple cancer cells. However, the role of CtBP2 in non-small cell lung cancer (NSCLC) remains uncertain. Our western blotting and immunohistochemistry assays revealed that CtBP2 expression was obviously increased in NSCLC tissues and cells. In addition, the chi-square test and Kaplan-Meier analysis showed that over-expression of CtBP2 correlates with more invasive tumor phenotype and poor prognosis. In vitro studies with serum starvation-refeeding and CtBP2-shRNA transfection assay demonstrated that CtBP2 expression facilitates NSCLC cell proliferation and reduces sensitivity to cis-diamminedichloroplatinum (CDDP). The possible signaling transduction pathways were investigated, and the immunoprecipitation assay revealed that CtBP2 interacts directly with DvL1. Depletion of CtBP2 resulted in inhibited DvL1 expression and decreased expression of downstream genes. Moreover, our study showed that CtBP2 knockdown enhanced NSCLC cell sensitivity to CDDP through inhibition of the Wnt/β-catenin pathway. These results suggest that CtBP2 plays a crucial role in NSCLC progression and CDDP sensitivity, and that CtBP2 depletion can provide a new target for NSCLC treatment.

Abstract
BACKGROUND Patients with Parkinson's disease (PD) are at a lower risk of suffering cardiovascular events, but the underlying factors for this decreased risk remain unclear. Serum triglycerides (TG) and total cholesterol (TC), and their expression relative to high-density lipoprotein cholesterol (TG/HDL-C and TC/HDL-C), are independent predictors of cardiovascular events. This study aimed to determine if PD patients have decreased lipid levels and lipid ratios, which may underlie the decreased risk of coronary heart disease (CHD). METHODS This retrospective study included 92 PD patients (PD group), 450 control subjects with no CHD (OD group), and 450 CHD patients (CHD group). We analyzed serum lipid levels and lipid ratios in each group. RESULTS There were significant differences in TC (F = 10.459, p < 0.0001), TG (F = 46.856, p < 0.0001), low density lipoprotein cholesterol (LDL-C) (F = 6.910, p = 0.001), high density lipoprotein cholesterol HDL-C (F = 30.694, p < 0.0001), TC/HDL-C (F = 32.675, p < 0.0001), and TG/HDL-C (F = 45.554, p < 0.0001) between all three groups; TC/LDL-C (F = 2.518, p = 0.081) was not significantly different between groups. Compared to the CHD group, PD patients had lower TC (p < 0.0001), TG (p < 0.0001), LDL-C (p = 0.001), TG/HDL-C (p < 0.0001), and TC/HDL-C (p < 0.0001); TC/LDL-C (p = 0.563) and HDL-C (p = 0.196) were not significantly different. TC and LDL-C levels were positively correlated within individual groups (all p < 0.0001). In addition, TG and HDL-C were negatively correlated in the OD and CHD groups (p < 0.0001); no significant negative association was observed in the PD group (p = 0.077). TG/HDL and LDL-C levels were inversely correlated in the CHD group (p < 0.0001) and weakly positively correlated in the PD (p = 0.159) and OD (p = 0.199) groups. CONCLUSIONS TC/HDL and TG/HDL ratios were significantly lower in PD patients compared to CHD patients, suggesting there is a strong correlation between lipid ratios and incidence of CHD in PD patients.

Abstract
Interleukin 27 (IL-27) regulates T cell function and is involved in inflammation. It has been reported that human placenta-derived mesenchymal stromal cells (hPMSCs) can inhibit T cell responses and attenuate inflammation reactions. However, it is unclear whether IL-27 can regulate hPMSC function. Here, we examined the effects of IL-27 upon adherence, migration, and proliferation as well as the immunomodulatory effects of hPMSCs. The results show that IL-27 receptor α chain (IL-27Rα) is expressed in hPMSCs. IL-27 at 30 ng/ml inhibited hPMSC adherence and proliferation, while the migration of hPMSCs was promoted with IL-27 at doses of 20 or 30 ng/ml, as determined with use of real-time cell analysis (RTCA). Moreover, IL-27 promoted regulatory effects of hPMSCs through enhancing Th2 and suppressing Th1 subset generation from activated T cells in human peripheral blood. IL-27 also enhanced the ability of hPMSCs to secrete IL-10 from CD4+T cells through increased expression levels of the programmed death ligand 1 (PDL1) in hPMSCs via the Janus kinase (JAK)/signal transducer and activator of transcription 1 (STAT1) signaling pathway. In conclusion, IL-27 has significant modulatory effects on adherence, proliferation, and migration of hPMSCs. IL-27 increased PDL1 expression levels in hPMSCs via the JAK/STAT1 pathway, which then enhanced the regulatory effects of hPMSCs upon Th1 and Th2 cell generations and IL-10 secretion from CD4+T cells.

Abstract
Cell therapy has been shown to be a key clinical therapeutic option for central nervous system diseases or damage. Standardization of clinical cell therapy procedures is an important task for professional associations devoted to cell therapy. The Chinese Branch of the International Association of Neurorestoratology (IANR) completed the first set of guidelines governing the clinical application of neurorestoration in 2011. The IANR and the Chinese Association of Neurorestoratology (CANR) collaborated to propose the current version "Clinical Cell Therapy Guidelines for Neurorestoration (IANR/CANR 2017)". The IANR council board members and CANR committee members approved this proposal on September 1, 2016, and recommend it to clinical practitioners of cellular therapy. These guidelines include items of cell type nomenclature, cell quality control, minimal suggested cell doses, patient-informed consent, indications for undergoing cell therapy, contraindications for undergoing cell therapy, documentation of procedure and therapy, safety evaluation, efficacy evaluation, policy of repeated treatments, do not charge patients for unproven therapies, basic principles of cell therapy, and publishing responsibility.

Abstract
Background This study aimed to assess the efficiency of anterior fissureless uniport (AFU) thoracoscopic lobectomy for early stage right upper non-small cell lung cancer (NSCLC). Methods Between June 2014 and Dec 2016, 162 consecutive NSCLC patients who underwent thoracoscopic right upper lobectomy (RUL) by AFU approach (AFU group, n=65) or posterior intra-fissure triple-port dissection (PIFT group, n=97) were enrolled. A propensity-matched analysis was used to compare perioperative outcomes, safety and efficiency between the two groups. Results Propensity matching produced 40 pairs in this retrospective study. During the operation, lobectomy took less time in the AFU group compared with the PIFT group, while no statistical differences in mediastinal lymphadenectomy time, intraoperative blood loss, and total of lymph nodes harvested were found between the two groups. Postoperatively, length of hospital stay (LOS) and time of postoperative air leak were significantly reduced in AFU group than in PIFT group. However, the overall complication rate and volume of pleural effusion drainage within 48 h were similar. Compared with the PIFT group, visual analogue scale (VAS) of 3 postoperative days in AFU group was slighter. Conclusions In RUL, AFU thoracoscopic approach is safe, efficient and easily maneuverable, which would reduce the duration of lobectomy, LOS and time of postoperative air leak. Postoperative pain is also mild.
