Effect of superior cervical ganglion block on cardiac function and NLRP3 signaling pathway in a rat model of myocardial ischemia-reperfusion / 中华麻醉学杂志

Objective:To evaluate the effect of superior cervical ganglion block (SCGB) on cardiac function and nucleotide like receptor protein 3 (NLRP3) signaling pathway in a rat model of myocardial ischemia-reperfusion (I/R).Methods:Sixty healthy SPF male Sprague-Dawley rats, weighing 250-300 g, aged 2-3 months, were divided into 4 groups ( n=15 each) using a random number table method: sham operation group (sham group), myocardial I/R group (IR group), myocardial I/R + normal saline group (IR+ NS group), and myocardial I/R + SCGB group (IR+ SCGB group). Myocardial I/R model was developed by ligation of the left anterior descending branch of the coronary artery for 45 min followed by restoration of blood flow in anesthetized aninals. IR+ SCGB group received SCGB (0.25% ropivacaine 0.1 ml) at 10 min before reperfusion once a day for 2 consecutive weeks, while 0.9% sodium chloride was given instead of ropivacaine in IR+ NS group. Blood samples were collected at 24 h and 14 days of reperfusion for determination of serum concentrations of norepinephrine (NE), troponin T (TnT), tumor necrosis factor-alpha (TNF-α), interleukin-18 (IL-18) and IL-1β by enzyme-linked immunosorbent assay. Echocardiography was performed before ischemia and at 14 days of reperfusion, and left ventricular short axis shortening rate (FS), ejection fraction (EF), and cardiac output (CO) were measured. The rats were sacrificed at 14 days of reperfusion and the hearts were taken for determination of the contents of norepinephrine (NE) in myocardial tissues in the infarction area (by enzyme-linked immunosorbent assay), percentage of myocardial fibrosis area (by Masson staining), M1 macrophage marker CD68 + cell count in the infarction area (by immunohistochemical method), and expression of NLRP3 and gasdermin D (GSDMD) in myocardial tissues (by Western blot). Results:Compared with Sham group, the serum concentrations of TnT, TNF-α, IL-18 and IL-1β, percentage of myocardial fibrosis area, and NE levels in serum and myocardial tissues were significantly increased, the expression of NLRP3 and GSDMD in myocardial tissues was up-regulated, CD68 + cell count was increased, and EF, CO and FS were decreased in IR group ( P<0.05). Compared with IR group, the serum concentrations of TnT, TNF-α, IL-18 and IL-1β, percentage of myocardial fibrosis area, and NE levels in serum and myocardial tissues were significantly decreased, the expression of NLRP3 and GSDMD in myocardial tissues was down-regulated, CD68 + cell count was decreased, and EF, CO and FS were increased in IR+ SCGB group ( P<0.05), and no statistically significant changes were found in the parameters mentioned above in IR+ NS group ( P>0.05). Conclusions:SCGB can improve the cardiac function in a rat model of myocardial I/R, and the mechanism may be related to the inhibition of NLRP3 signaling pathway.

Mechanism of transforming growth factor- β1 induce renal fibrosis based on transcriptome sequencing analysis / 浙江大学学报·医学版

OBJECTIVES@#To explore the mechanism of transforming growth factor-β1 (TGF-β1) induce renal fibrosis.@*METHODS@#Renal fibroblast NRK-49F cells treated with and without TGF-β1 were subjected to RNA-seq analysis. DESeq2 was used for analysis. Differentially expressed genes were screened with the criteria of false discovery rate<0.05 and l o g 2 F C >1. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed for differentially expressed genes. Genes encoding transcription factors were further screened for differential expression genes. Then, the expression of these genes during renal fibrosis was verified using unilateral ureteral obstruction (UUO)-induced mouse renal fibrosis model and a public gene expression dataset (GSE104954).@*RESULTS@#After TGF-β1 treatment for 6, 12 and 24 h, 552, 1209 and 1028 differentially expressed genes were identified, respectively. GO analysis indicated that these genes were significantly enriched in development, cell death, and cell migration. KEGG pathway analysis showed that in the early stage of TGF-β1 induction (TGF-β1 treatment for 6 h), the changes in Hippo, TGF-β and Wnt signaling pathways were observed, while in the late stage of TGF-β1 induction (TGF-β1 treatment for 24 h), the changes of extracellular matrix-receptor interaction, focal adhesion and adherens junction were mainly enriched. Among the 291 up-regulated differentially expressed genes treated with TGF-β1 for 6 h, 13 genes (Snai1, Irf8, Bhlhe40, Junb, Arid5a, Vdr, Lef1, Ahr, Foxo1, Myc, Tcf7, Foxc2, Glis1) encoded transcription factors. Validation in a cell model showed that TGF-β1 induced expression of 9 transcription factors (encoded by Snai1, Irf8, Bhlhe40, Junb, Arid5a, Vdr, Lef1, Myc, Tcf7), while the expression levels of the other 4 genes did not significantly change after TGF-β1 treatment. Validation results in UUO-induced mouse renal fibrosis model showed that Snai1, Irf8, Bhlhe40, Junb, Arid5a, Myc and Tcf7 were up-regulated after UUO, Vdr was down-regulated and there was no significant change in Lef1. Validation based on the GSE104954 dataset showed that IRF8 was significantly overexpressed in the renal tubulointerstitium of patients with diabetic nephropathy or IgA nephropathy, MYC was highly expressed in diabetic nephropathy, and the expressions of the other 7 genes were not significantly different compared with the control group.@*CONCLUSIONS@#TGF-β1 induces differentially expressed genes in renal fibroblasts, among which Irf8 and Myc were identified as potential targets of chronic kidney disease and renal fibrosis.

Objective:To explore the expressions of miRNA-17-92 (miR-17-92) cluster and mitofusin 2 (MFN2) protein in endometrial cancer (EC) and their clinical significances.Methods:A total of 72 EC tissues, 36 endometrial lesions of patients with endometrial atypical hyperplasia, and 22 normal endometrial tissues from total hysterectomy for grade Ⅲ cervical intraepithelial neoplasia in the Second Affiliated Hospital of Shandong First Medical University from January 2008 to December 2014 were collected; at the same time, all patients' paraffin-embedded tissues were collected. Real-time quantitative polymerase chain reaction was used to detect the expression level of miR-17-92 in each tissue. Immunohistochemical SP method was used to detect the localization and expression level of MFN2 protein in each paraffin-embedded tissue. The correlation of miR-17-92 and MFN2 protein with clinicopathological features of EC patients was analyzed. Kaplan-Meier method was used to draw survival curve of patients with different miR-17-92 and MFN2 levels, and log-rank test was made; Cox proportional hazard regression model was used for multivariate survival analysis.Results:The relative expression of miR-17-92 in EC, atypical hyperplasia and normal endometrial tissues were 1.49±0.46, 1.01±0.30 and 0.69±0.20, respectively. The expression of miR-17-92 in EC tissues was higher than that in the other endometrial tissues, and the differences were statistically significant (both P < 0.01). The high-expression rates of MFN2 protein in EC, atypical hyperplasia and normal endometrial tissues were 20.8% (15/72), 39.4% (13/33) and 85.0% (17/20); the high-expression rate of MFN2 protein in EC tissue was lower than that in the other endometrial tissues, and the differences were statistically significant (both P < 0.012 5). In EC patients, the relative expression of miR-17-92 in patients with histological type Ⅱ was higher than that in patients with histological type Ⅰ ( P < 0.05); the relative expression of miR-17-92 in patients with myometrial invasion depth ≥1/2 were higher than that in patients with myometrial invasion depth <1/2 ( P < 0.05). The high-expression rate of MFN2 protein in patients with histological type Ⅰ was higher than that in patients with histological type Ⅱ ( P < 0.05); the high-expression rate of MFN2 protein in patients with International Federation of Gynecology and Obstetrics (FIGO) grade Ⅰ was higher than that in patients with FIGO grade Ⅱ and Ⅲ ( P < 0.05). When the EC patients were grouped according to the median relative expression of miR-17-92 (1.421), Kaplan-Meier survival analysis showed that the median overall survival (OS) time of the miR-17-92 low-expression group (36 cases) was not reached, and the high-expression group (36 cases) was 36 months (95% CI 32-42 months), and the difference in OS between the two groups was statistically significant ( P = 0.049); the median OS time of the MFN2 high-expression group (15 cases) was not reached, and the low-expression group (57 cases) was 38 months (95% CI 33-41 months), and the difference in OS between the two groups was statistically significant ( P = 0.046). Multivariate Cox regression analysis showed that the expression levels of miR-17-92 and MFN2 were independent influencing factors for the survival of EC patients ( HR = 3.10, 95% CI 1.36-7.07, P = 0.007; HR = 0.30, 95% CI 0.09-0.99, P = 0.048). Conclusion:The high-expression of miR-17-92 and low-expression of MFN2 protein in EC tissues may be involved in the occurrence and development of EC, and they can be used as indicators for judging the prognosis of EC patients.

A clinical study on nasal atomization of budesonide combined with hypertonic saline / 实用医学杂志

Objective To study the clinical efficacy of respiratory allergic diseases in children treated by nasal atomization of budesonide combined with 3% hypertonic saline. Methods Children diagnosed as upper air-way cough syndrome or mild to moderate asthma without being controlled by anti-asthma treatment were included in the study.They contracted with complications of nasal congestion and/or running noseand other symptoms,and na-sal CT confirmed the nasal lesions.Thirty children undergoing conventional treatment(conventional drug therapy+keeping away from allergen)were defined as the control group. 89 children treated with nasal spray therapy(con-ventional drug therapy + keeping away from allergen + nasal spray treatment)were defined as the therapy group. The treatment group was subdivided into IgE-mediated group and non-IgE-mediated group according to IgE level. The treatment course was 7 days.The clinical symptoms score,nasal symptom visual scale(VAS),peak expirato-ry flow(PEF)index were observed and analyzed. Results The clinical symptom score and nasal VAS showed a decreasing trend and the percentage of PEF showed an increasing trend in the two groups within 1 week after treat-ment.The clinical symptom score and nasal VAS score of the treatment group were significantly lower than those of the control group,while the PEF%value was significantly higher.The difference in treatment method was interact-ed with the treatment time(P<0.05).The percentage of PEF in the non-IgE-mediated group was significantly high-er than that of IgE-mediated group 1 week after treatment(P < 0.05). Conclusion The nasal atomization of budesonide combined with hypertonic saline in the treatment of children with respiratory allergic diseases is effec-tive and of a good clinical value.

Effects of Edaravone on protein expression of the mitogen-activated protein kinase/extracellular signal-regulated protein kinase signaling pathway in elderly patients with acute ischemic stroke / 中华老年医学杂志

Objective To investigate the effects of Edaravone on cognitive dysfunction and on protein expression of the mitogen-activated protein kinase/extracellular signal-regulated protein kinase (MAPK/ERK)signaling pathway in elderly patients with acute ischemic stroke. Methods A total of 100 elderly patients with acute ischemic cerebral stroke admitted to our hospital from January 2011 to December 2015 were enrolled in this study.During the corresponding period ,100 healthy individuals receiving regular check-ups were selected as the control group. The effects of Edaravone on cognitive function in elderly patients with acute ischemic cerebral stroke were assessed.Serum proteins related to the MAPK/ERK signaling pathway were assayed. Results Elderly patients with acute ischemic stroke showed obvious cognitive dysfunction ,and scores on memory ,orientation ,attention ,calculation language and recall significantly decreased(P＜0.01)but returned to normal after Edaravone treatment (P＜0.01).Compared with the control group ,serum protein expression of rat sarcoma (Ras) ,rapidly accelerated fibrosarcoma(Raf) ,hypoxia inducible factor-1α(HIF-1α) ,connective tissue growth factor (CTGF),extracellular signal-regulated protein kinase(ERK1),ERK2 ,MAPK/ERK kinase(MEK), interleukin-1(IL-1) ,tumor necrosis factor-α(TNF-α) ,vascular endothelial growth factor (VEGF) , tissue inhibitor of metalloproteinase (TIMP) ,nerve growth factor (NGF)and its receptors was significantly downregulated(P＜0.01) ,while expression of leptin and its receptors was upregulated in elderly patients with acute ischemic cerebral stroke ( P ＜ 0.01 ). Expression levels of the above downregulated proteins clearly recovered after Edaravone treatment ( P ＜ 0.01 ). Conclusions Edaravone has favorable effects on cognition dysfunction in elderly patients with acute ischemic cerebral stroke ,which may be related to the regulation of the MAPK/ERK signaling pathway.

Classification and phylogenetic analysis of the genus Mobiluncus based on matrix-assisted laser de-sorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and whole genome sequen-cing / 中华微生物学和免疫学杂志

Objective To identify Mobiluncus species with matrix-assisted laser desorption/ioniza-tion time-of-flight mass spectrometry (MALDI-TOF MS) and 16S rRNA gene sequencing and to analyze anti-biotic resistance genes and phylogenetic relationships among Mobiluncus species with whole genome sequen-cing. Methods Twenty-five Mobiluncus strains were isolated after anaerobic culture of 65 vaginal secretion samples of patients with bacterial vaginosis (BV) and identified to species level by MALDI-TOF MS and 16S rRNA gene sequencing. The whole genome DNA of each strain was extracted for next-generation sequencing. SPAdes was used to assembly genomes. Resistance genes were searched in ARGD database. The core ge-nome of all isolates was analyzed by Harvest to construct phylogenetic tree. Results MALDI-TOF MS could only identify Mobiluncus curtisii, while 16S rRNA gene sequencing could identify both Mobiluncus mulieris and Mobiluncus curtisii. Results of the whole genome sequencing showed that tetracycline resistance gene tet ( o) and macrolides resistance gene erm(x) were the two predominant acquired resistance genes of Mobilun-cus with a positive rate of 84. 7% and 61. 5% respectively. Intra-species relationships of the two Mobiluncus species were close, but a distant phylogenetic relationship was found between the two species. Conclusion This study shows that MALDI-TOF MS can't be used to identify Mobiluncus mulieris at present. Mobiluncus strains have potential resistance to tetracycline and macrolides. Intra-species evolution of Mobiluncus is slow, which indicates that there is no growing trend towards new species for the time being.

An acoustic-articulatory study of the nasal finals in students with and without hearing loss / 生物医学工程学杂志

The central aim of this experiment was to compare the articulatory and acoustic characteristics of students with normal hearing (NH) and school aged children with hearing loss (HL), and to explore the articulatory-acoustic relations during the nasal finals. Fourteen HL and 10 control group were enrolled in this study, and the data of 4 HL students were removed because of their high pronunciation error rate. Data were collected using an electromagnetic articulography. The acoustic data and kinematics data of nasal finals were extracted by the phonetics and data processing software, and all data were analyzed by test and correlation analysis. The paper shows that, the difference was statistically significant ( <0.05 or <0.01) in different vowels under the first two formant frequencies (F1, F2), the tongue position and the articulatory-acoustic relations between HL and NH group. The HL group's vertical movement data-F1 relations in /en/ and /eng/ are same as NH group. The conclusion of this study about participants with HL can provide support for speech healing training at increasing pronunciation accuracy in HL participants.
