Background and Aims Recent evidence suggest that microbiota is associated with almost all major types of diseases, including cardiovascular diseases. However, its role in Acute Cerebral Infarction remains unexplored. It is important to understand the diversity and distribution of gut microbiota (GM) in patients with Acute Cerebral Infarction and the role that GM plays in this type of disease. Methods We performed pyrosequencing on the gut microbiota of 40 individuals in order to elucidate whether the composition of the microbiota differs between patients with Acute Cerebral Infarction and healthy controls: Of these individuals, there were 31 with Acute Cerebral Infarction and nine controls. We applied linear regression to calculate the correlation between the gut flora and disease risk factors. Finally, KEGG functional enrichment analysis was conducted to examine the correlation between the gut flora and Acute Cerebral Infarction. Results The overall microbial structure was similar in both the controls and the patients, but the control group had higher relative presence of Blautia obeum while the presence of Streptococcus infantis and Prevotella copri were relatively higher in the patient group. Using linear regression, we found that Blautia obeum was negatively associated with white blood cell count and Streptococcus infantis was positively correlated with creatinine and lipoprotein. The KEGG pathway analysis indicated that the bio-pathways including methane metabolism, lipopolysaccharide synthesis, bacterial secretion, and flagellar assembly of the gut microbiota in the patient group was expressed differently than that of the controls. We identified three differentially expressed gut microbial functions in Acute Cerebral Infarction and found four bacterial pathways that might be related to the development of this disease. Conclusions Our study identified three abnormally-expressed bacteria—Blautia obeum, Streptococcus infantis, and Prevotella copri—in patients with Acute Cerebral Infarction compared with healthy controls. It reveals a correlation of these bacterial species with Acute Cerebral Infarction as they relate to disease factors and functional pathways. These findings may shed light on the treatment of cerebral infarction because gut microbiota could serve as a potential therapeutic approach for the treatment of cardiovascular and metabolic diseases.

To investigate the expression and clinical significance of lysosomal granule glycoprotein 63 (CD63), P-selectin (CD62P) and endothelial cell plasminogen activator inhibitor (PAI-1) in patients with acute cerebral infarction. A total of 106 patients with acute cerebral infarction (ACI) admitted to our hospital from January to July in 2017 were selected as the patient group; 80 healthy subjects for physical examination in our hospital were selected as the control group. The expression levels of serum CD63, CD62P, and PAI-1 of the subjects were detected. The levels of CD63, CD62P, and PAI-1 in the serum of the patient group were significantly higher than those in the control group. There was a positive correlation between serum CD63 and CD62P (r = 0.672, P < 0.05) in the patient group. There was a positive correlation between serum CD63 and PAI-1 (r = 0.643, P < 0.05) in the patient group. There was also a positive correlation between serum CD62P and PAI-1 (r = 0.601, P < 0.05) in the patient group. Moreover, in other subtypes of cerebral infarction, the expression of CD63, CD62P, and PAI-1 was significantly higher than that of lacunar infarction. CD63, CD62P, and PAI-1 are highly expressed in peripheral blood mononuclear cells (PBMC) and serum of patients with ACI, which may be closely related to the occurrence and development of patients with ACI. These indices may be used as indicators of clinical diagnosis and prognosis in patients with ACI.

AbstractObjectiveThe aim of this study is to investigate the dysbiosis characteristics of gut microbiota in patients with cerebral infarction (CI) and its clinical implications.MethodsStool samples were collected from 79 CI patients and 98 healthy controls and subjected to 16S rRNA sequencing to identify stool microbes. Altered compositions and functions of gut microbiota in CI and its correlation with clinical features were investigated. Random forest and receiver operating characteristic analysis were used to develop a diagnostic model.ResultsMicrobiota diversity and structure between CI patients and healthy controls were overall similar. However, butyrate-producing bacteria (BPB) were significantly reduced in CI patients, while lactic acid bacteria (LAB) were increased. Genetically, BPB-related functional genes were reduced in CI patients, whereas LAB-related genes were enhanced. The interbacterial correlations among BPB in CI patients were less prominent than those in healthy controls. Clinically, BPB was negatively associated with the National Institutes of Health Stroke Scale (NIHSS), while LAB was positively correlated with NIHSS. Both BPB and LAB played leading roles in the diagnostic model based on 47 bacteria.ConclusionsThe abundance and functions of BPB in CI patients were significantly decreased, while LAB were increased. Both BPB and LAB displayed promising potential in the assessment and diagnosis of CI.

The aim of this investigation was to define the concentrations of serum proteinase — plasmin — and some of proteinase inhibitors, such as α2-macroglobulin (MG) and α1-antitrypsin (AT), in order to study their role in cerebral infarction (CI) and discircular encephalopathy (DE) pathogenesis. We have investigated 30 patients with cerebral infarction, 30 patients with discircular encephalopathy and 60 serum samples of the healthy people as a control. Plasmin (Pl), AT and MG levels have been defined with rocket immunoelectrophoresis method. We have found a significant Pl decrease in both group patients as compared to the control. The decrease has been (95,83 ± 4,3) mkg/ml in CI patients’ serum, (83,49 ± 3,79) mkg/ml in DE patients and (112,98 ± 2,66) mkg/ml in the control group. AT concentration has been increased in DE patients’ serum [(2,44 ± 0,15) g/l], MG concentration has decreased significantly [(1,08 ± 0/09) g/l] as compared to the control. On the contrary, MG serum concentration (1,72 ± 0/08 g/l) in CI patient group has not differed from the control [(1,64 ± 0,04) g/l] but it has been accompanied by AT level increase [(2,50 ± 0,16) g/l at patients and (1,78 ± 0,04) g/l at control]. We think that these differences can be used during differential diagnostics of the investigated diseases.

Background: We aimed to explore the effect of comprehensive cerebral protection on cerebral oxygen metabolism and vascular endothelial function in elderly patients with acute cerebral infarction. Methods: A total of 168 elderly patients with acute cerebral infarction treated in The First Affiliated Hospital of Nanchang University, China from January 2016 to January 2018 were selected. The patients were divided into a control group and an observation group using random number method, n=84. Patients in the observation group were given comprehensive cerebral protection treatment, and patients in the control group were treated with conventional standardized treatments. The changes of cerebral oxygen metabolism, hemorheology and vascular endothelial function before and after treatment were compared between the two groups. Results: After treatment, oxygen content in arteries and internal jugular veins (Da-vO2), ofoxygen uptake fraction (OEF), Oxygen saturation (SpO2), nitric oxide (NO) were increased in both groups in comparison to before treatment, jugular venous oxygen saturation (SjvO2), brain oxygen uptake rate (ERO2), endothelin (ET), intracranial pressure (ICP), whole blood viscosity, plasma viscosity, reduced viscosity of whole blood, and hematocrit were decreased. However, the changes in the observation group were larger than those in the control group, the difference was statistically significant (P<0.05). Conclusion: The treatment of cerebral infarction in elderly patients with acute cerebral infarction can effectively improve the cerebral oxygen metabolism and vascular endothelial function and improve the blood rheology, which has important clinical value.

Objective: To observe the clinical efficacy of sequential butylphthalide therapy combined with dual antiplatelet therapy in the treatment of elderly patients with acute cerebral infarction (ACI). Methods: One hundred and twenty-two elderly patients with ACI who were admitted to the department of neurology of our hospital at May 2016-August 2018 were selected grouped into a control group and an observation group by random number table method, 61 in each group. On the basis of conventional treatment, the patients in the control group were given dual antiplatelet therapy (aspirin enteric-coated tablets + clopidogrel bisulfate tablets), while the patients in the observation group were given sequential butylphthalide therapy on the basis of the control group. The clinical effects of the two groups were compared after four weeks of treatment, and the changes of National Institutes of Health Stroke Scale (NIHSS), ADL score, plasma 3-mercaptopyruvate sulphurtransferase (3-MST) and Amyloid β42 (Aβ42) levels and the occurrence of adverse reactions during treatment were recorded. Results: The clinical efficacy of the observation group was better than that of the control group (P<0.05). There was no significant difference in NIHSS and ADL scores between the two groups before treatment (P>0.05). After treatment, the NIHSS and ADL scores of the observation group were better than those of the control group (P<0.05). There was no significant difference in plasma levels of 3-MST and AB42 between the two groups before treatment (P>0.05). The level of plasma 3-MST in the observation group was higher than that in the control group, and the level of plasma Aβ42 was lower than that in the control group (P<0.05). No serious adverse reactions occurred during the treatment period in both groups. Conclusion: Butylphthalide sequential therapy combined with dual antiplatelet therapy is effective in the treatment of elderly ACI. It can effectively improve the plasma level of 3-MST and decrease the plasma level of Aβ42, which is conducive to improving the living ability and neurological function of patients and has high safety. doi: https://doi.org/10.12669/pjms.36.4.1831 How to cite this:Wo X, Han J, Wang J, Wang X, Liu X, Wang Z.

Abstract Mammals have a symbiotic relationship with various microorganisms called microbiota throughout their lives. These microorganisms are known to affect the host's physiology, health, and even mental balance. In the harbor of the densest and most diverse microorganisms in mammals, the curved structure of the intestines and their rich nutrient content are effective. The development of the gut microbiota is regulated by a complex interaction between host and environmental factors, including diet and lifestyle. Herein, it is aimed to elucidate the changes in the gut microbiota of rats living in urban and rural habitats. All taxonomic changes in the gut microbiota of wild rats belonging to Rattus rattus species caught from urban and rural areas of Western Anatolian (Bilecik province) were examined comparatively by 16S rRNA next-generation sequencing technique. Laboratory rats were used as a control group for comparison. Thus, 2000 different bacterial species were identified in gut microbiota. According to the Shannon and Simpsons values ​​calculated, laboratory rats showed the highest species diversity. When the similarities of microbiota profiles were compared with the principal coordinate analysis (PcoA), bacterial populations showed variability among different habitats. The comparison of species richness between the groups with the species rarefaction technique revealed higher species richness in all wild rats, especially in the rural habitat, compared to laboratory rats. Food sources were determined as the most important factor contributing to species richness and diversity. While the increased food variety boosted species richness, species diversity was increased due to the diminished food variety.

A lot of previous studies have recently reported that the gut microbiota influences the development of colorectal cancer (CRC) in Western countries, but the role of the gut microbiota in Chinese population must be investigated fully. The goal of this study was to determine the role of the gut microbiome in the initiation and development of CRC. We collected fecal samples of 206 Chinese individuals: 59 with polyp (group P), 54 with adenoma (group A), 51 with colorectal cancer (group CC), and 42 healthy controls (group HC).16S ribosomal RNA (rRNA) was used to compare the microbiota community structures among healthy controls, patients with polyp, and those with adenoma or colorectal cancer. Our study proved that intestinal flora, as a specific indicator, showed significant differences in its diversity and composition. Sobs, Chao, and Ace indexes of group CC were significantly lower than those of the healthy control group (CC group: Sobs, Chao, and Ace indexes were 217.3 ± 69, 4265.1 ± 80.7, and 268.6 ± 78.1, respectively; HC group: Sobs, Chao, and Ace indexes were 228.8 ± 44.4, 272.9 ± 58.6, and 271.9 ± 57.2, respectively). When compared with the healthy individuals, the species richness and diversity of intestinal flora in patients with colorectal cancer were significantly reduced: PCA and PCoA both revealed that a significant separation in bacterial community composition between the CC group and HC group (with PCA using the first two principal component scores of PC1 14.73% and PC2 10.34% of the explained variance, respectively; PCoA : PC1 = 14%, PC2 = 9%, PC3 = 6%). Wilcox tests was used to analyze differences between the two groups, it reveals that Firmicutes (P=0.000356), Fusobacteria (P=0.000001), Proteobacteria (P=0.000796), Spirochaetes (P=0.013421), Synergistetes (P=0.005642) were phyla with significantly different distributions between cases and controls. The proportion of microorganism composition is varying at different stages of colon cancer development: Bacteroidetes (52.14%) and Firmicutes (35.88%) were enriched in the healthy individuals; on the phylum level, the abundance of Bacteroidetes (52.14%-53.92%-52.46%–47.06%) and Firmicutes (35.88%-29.73%-24.27%–25.36%) is decreasing with the development of health-polyp-adenomas-CRC, and the abundance of Proteobacteria (9.33%-12.31%-16.51%–22.37%) is increasing. PCA and PCOA analysis showed there was no significant (P<0.05) difference in species similarity between precancerous and carcinogenic states. However, the composition of the microflora in patients with precancerous lesions (including patients with adenoma and polyp) was proved to have no significant disparity (P<0.05). Our study provides insights into new angles to dig out potential biomarkers in diagnosis and treatment of colorectal cancer and to provide scientific advice for a healthy lifestyle for the sake of gut microbiota.

BACKGROUND: Acute cerebral infarction (ACI) is a common cerebrovascular disease in clinical practice. OBJECTIVE: The present study aims to investigate the efficacy and safety of alteplase and urokinase in treating ACI. METHODS: A total of 96 patients with ACI, who were treated with alteplase and urokinase, were selected as the main subjects. Among these patients, 45 patients with ultra-early acute cerebral infarction, who received intravenous thrombolysis with RT-PA (alteplase), were included in the treatment group, while 51 patients with acute cerebral infarction, who were treated with urokinase in the same time period, were included in the control group. RESULTS: The National Institute of Health Stroke Scale (NIHSS) scores were significantly lower in the treatment group and control group (P< 0.05) at two hours, seven days and 14 days after thrombolysis, when compared to those before thrombolysis. The bleeding rate was significantly lower in the control group, when compared to the treatment group (P< 0.05). CONCLUSION: The intravenous thrombolysis with urokinase or alteplase in the ultra-early stage of acute cerebral infarction can reduce the neurological injury symptoms and effectively improve the prognosis of patients with stroke. Urokinase is lower in risk of bleeding, but better in safety, when compared to alteplase.

Abstract Objectives Triggering receptor expressed on myeloid cells (TREM) -1 is a receptor as a member of the immunoglobulin superfamily expressed on the cell-surface of neutrophils, monocytes and macrophages. This receptor amplifies the inflammatory response, activating the signaling pathway. TREM-1 expression is associated with mature myeloid cell development. TREM-1 is shed from the membrane of activated macrophages without the transmembrane and intracellular domains, and can be found as soluble TREM (sTREM)-1. Soluble TREM-1 is thought to negatively regulate TREM receptor signaling. Some studies currently reported that TREM-1 regulates the malignant behavior of cancer cells in lung cancer and HCC. However, no related studies about the role of TREM-1 in leukemia have been carried out. The aims of this study was investigated the TREM-1 expression in myelogenous leukemia cells. Methods Thirty-five patients with AML, twenty-five patients with CML and a control group of eleven healthy people were subjected to the study. TREM-1 expressions on the surfaces of leukemia cells were measured by flow cytometry. Plasma sTREM-1 levels were measured by ELISA. Results In this study, our results provide the first evidence that TREM-1 was differentially expressed in myelogenous leukemia cells. The TREM-1 mean ratio of median fluorescence intensity (mean ratio of MFI) was 3.13±0.88 and 2.52±0.40 in CML and AML patients, respectively. The TREM-1 mean ratio of MFI was 3.03±1.40 in myelogenous leukemia cell lines (K562, HL60, THP-1). The TREM-1 mean ratio of MFI was 5.37±0.88 in healthy controls. Compared to healthy controls, myelogenous leukemia cells had decreased TREM-1 expressions (P<0.001). The TREM-1 mean ratio of MFI was 4.89±0.60 in patients who are in complete remission after Novartis's Gleevec therapy. Compared with CML patient groups, patients who are in complete remission after Gleevec therapy had rising TREM-1 expressions (P<0.01). TREM-1 expressions of patients who are in complete remission after Gleevec therapy were slightly lower than the healthy controls, but this did not reach significance. No significant difference in TREM-1 expressions was seen between AML and CML patient groups, male and female patient groups, and cells derived from peripheral blood and bone marrow of the same leukemia patients (p>0.1). In addition, the plasma sTREM-1 levels were measured by ELISA. sTREM-1 levels was 48.54±57.63pg/mL for AML group and 43.72±23.93pg/mL for CML group. Results indicated that plasma sTREM-1 levels significantly higher in AML and CML patients than that in healthy controls (P<0.01). However, there was no significant difference in plasma sTREM-1 levels observed in AML patient group compared with CML patient group, male patients group compared with female patients group, and plasma from peripheral blood compared with plasma from bone marrow of the same leukemia patients (p>0.1). An ongoing project focuses on the relationship between the function of TREM-1 and occurrence, progression and prognosis of myelogenous leukemia, advances will be reported in time. Conclusion TREM-1 expression on leukemia cells was significantly lower in patients with AML and CML than those in healthy controls and patients in complete remission had increased TREM-1 expression. Patients with AML and CML had increased plasma soluble TREM-1. The TREM-1 expression on leukemia cells had an inverse correlation with plasma sTREM-1 level in AML and CML patients.
