Objective To investigate the clinical effect of homemade toilet stool on bed urination in spontaneous subarachnoid hemorrhage (SAH) patients.Methods The newly admitted 80 SAH patients with 0～2 level of Hunt-Hess grade were randomly divided into the observation group and the control group with 40 cases in each group.The control group was taken ordinary toilet stools and regular monitoring methods,and the observation group was taken homemade toilet stools and regular monitoring methods.Then the rate of urination,time of induced urination,blood pressure changes during induced urination and residual urine volume of bladder were compared within these two groups.Results The rate of successful urination in the observation group were significantly higher than that in the control group,and time of induced urination,blood pressure changes during induced urination,residual urine volume of bladder in the observation group were all significantly lower than those in the control group.Conclusions Homemade toilet stool is effective in promoting bed urination,shortening the time of induced urination,reducing the fluctuation of blood pressure during induced urination and the residual urine volume of bladder.

Objective To investigate the clinical efficacy and prognosis of early protective pulmonary ventilation and intra-aortic balloon pump(IABP)combined with percutaneous coronary intervention(PCI)in treating patients with acute myocardial infarction(AMI)complicated with cardiogenic shock(CS)and hypoxemia.Methods The 49 patients diagnosed as AMI complicated with CS and hypoxemia and treated with early protective pulmonary ventilation and IABP combined with PCI in Tianjin Chest Hospital from January 2015 to December 2015 were retrospectively analyzed.Major adverse cardiovascular events(MACE)including sudden cardiac death,recurrent myocardial infarction,heart failure and development of target vessel revascularization were recorded during one year of follow-up visits.Survival rate was analyzed and Cox regression analysis was used to explore risk factors for occurrence of MACE after the treatment.Results The revascularization of target vessel was successfully operated on all of the 49 patients.The mean time from attack to hospitalization was(6.2±1.5)hours,while the mean time from emergency room to balloon dilatation was(118.55±28.28)minutes.In these patients,30(61.2%)cases were diagnosed as STEMI,among which 23(76.6%)cases as anterior wall myocardial infarction and 5(16.7%)cases as inferior wall myocardial infarction.While the other 19(38.8%)cases were diagnosed as non-STEMI.Using coronary arteriography,46(93.9%)cases had multi-vessel coronary artery disease,among which 13(26.5%)cases were complicated with severe left main coronary artery disease and 27(55.1%)cases had severe vascular calcification.44(89.8%)cases had TIMI perfusion grade 3 blood flow after PCI,while 5(10.2%)cases did not achieve TIMI grade 3 blood flow.One(2.0%)case had serious complications and 12(24.5%)patients died in hospital.31(63.3%)patients survived 1 year during follow-up visits.Total number of MACE was 32(65.3%).Among these events,18(36.7%)died,4 cases(8.2%)had recurrent myocardial infarction,13 cases(26.5%)had heart failure(HF)and 5 cases(10.2%)had target vessel revascularization(TVR).The total event-free survival rate was 34.7%.Multivariable Cox regression analysis showed that severe vascular calcification〔HR(95%CI):2.677(1.184-6.054),P=0.018〕,TIMI grade blood flow less than level 3 after PCI〔HR(95%CI):26.289(6.314-109.470),P=0.000〕and more than 120 minutes from emergency room to balloon dilatation〔HR(95%CI):2.923(1.325-6.446),P=0.008〕were risk factors for MACE.Conclusions Early protective pulmonary ventilation and IABP combined with emergency PCI are safe and effective for treatment of patients with AMI complicated with CS and hypoxemia.The pattern of treatment can significantly decrease death rate and increase 1-year survival rate.

Objective: Schizophrenia (SCZ) is one of the most common and severe mental disorders. Modified electroconvulsive therapy (MECT) is the most effective therapy for all kinds of SCZ, and the underlying molecular mechanism remains unclear. This study is aim to detect the molecule mechanism by constructing the transcriptome dataset from SCZ patients treated with MECT and health controls (HCs). Methods: Transcriptome sequencing was performed on blood samples of 8 SCZ (BECT: before MECT; AECT: after MECT) and 8 HCs, weighted gene co-expression network analysis (WGCNA) was used to cluster the different expression genes, enrichment and protein-protein interaction (PPI) enrichment analysis were used to detect the related pathways. Results: Three gene modules (black, blue and turquoise) were significantly associated with MECT, enrichment analysis found that the long-term potentiation pathway was associated with MECT. PPI enrichment p-value of black, blue, turquoise module are 0.00127, <1×10-16 and 1.09×10-13, respectively. At the same time, EP300 is a key node in the PPI for genes in black module, which got from the transcriptome sequencing data. Conclusion It is suggested that the long-term potentiation pathways were associated with biological mechanism of MECT.

Objective: To investigate the features of plaques of saphenous venous graft (SVG) with virtual histology intravascular ultrasound (VH-IVUS) in patients underwent coronary artery bypass graft surgery. Methods: From March 2016 to March 2018, a total of 45 patients ((64.4±7.9) years old, 88.9% male (40 cases)) with ischemic symptoms after coronary artery bypass graft surgery and with coronary artery angiography evidenced SVG stenosis greater than or equal to 50%, who received percutaneous coronary intervention in Tianjin chest hospital were continuously included in this study, and the clinical data were retrospectively analyzed. VH-IVUS was performed before PCI to analyze plaque composition. The patients were divided into no smoking group (21 cases) and smoking group (24 cases), no diabetes group (30 cases) and diabetes group (15 cases), normal very low density lipoprotein cholesterin (VLDL-C) group (24 cases) and elevated VLDL-C group (21 cases), stable angina pectoris group (5 cases) and acute coronary syndrome group (40 cases), plaque burden (PB) < 70% group (11 cases) and PB ≥ 70% group (34 cases), without thin-cap fibroatheroma group (35 cases) and thin-cap fibroatheroma group (10 cases), and plaque features were compared between different groups. Results: The graft age was (8.9±3.7) years.The stenosis degree of SVG lesions was 90 (90, 98) %. The minimum lumen diameter was 1.6 (1.5, 1.8) mm. The vessel cross-sectional area was (12.1±4.0) mm². The plaque area was 8.6 (5.7,12.0) mm². The minimum lumen area was 2.5 (2.1,3.3) mm². The plaque burden was (75.3±8.3)%. The fibrotic tissue (FI) ratio was (65.1±10.1)%, fibrofatty plaque (FF) ratio was 13.8 (5.4,25.3) %, necrotic core tissue (NC) ratio was 12.0 (5.4,24.0)%, and dense calcium tissue (DC) ratio was1.0 (0.2,3.8)% in SVG lesions. There were no significant differences in SVG plaque area, FI area,FF area,NC area,and DC area between no smoking group and smoking group, no diabetes group and diabetes group, and normal VLDL-C group and elevated VLDL-C group. SVG plaque volume was significantly higher in acute coronary syndrome group than in stable angina pectoris group (262.2 (148.5,401.2) mm³ vs. 93.1 (50.6,155.9) mm³,P=0.006), and plaque area (10.1 (6.6,13.3) mm² vs. 5.0 (3.6,6.9) mm², P<0.001), FI area(4.8 (3.2,6.8) mm² vs. 2.8 (1.9,3.0) mm², P<0.001),and FF area (1.15 (0.60, 2.07) mm² vs. 0.30 (0.10,0.90) mm², P=0.009) were significantly larger in PB ≥ 70% group than in PB < 70% group.The NC area (1.75(0.40,2.78) mm² vs. 0.60 (0.20,1.30) mm², P=0.030) and DC area (0.35 (0.10,0.50) mm² vs. 0.00 (0.00,0.10) mm², P=0.006) were significantly larger in thin-cap fibroatheroma group than that in without thin-cap fibroatheroma group. Spearman correlation analysis showed that the plaque area of SVG lesion was positively correlated with FF area (r=0.64, P<0.001) and NC area (r=0.43, P=0.003). PB was positively correlated with FF area (r=0.50, P<0.001) and NC area (r=0.33, P=0.028). Graft age was positively correlated with FF area (r=0.30, P=0.047). Conclusions The main components of SVG plaque are fibrotic tissue, conversely, calcified tissue is rare in patients with SVG stenosis after coronary artery bypass graft surgery. Fibrofatty tissue is increased in the plaque in patients with PB ≥ 70%. The necrotic component is also increased in patients with thin-cap fibroatheroma. The fibrofatty component increases and the plaque tends to be unstable in proportion with increaing age of the graft in this patient cohort.

Despite exciting achievements with some malignancies, immunotherapy for hypoimmunogenic cancers, especially glioblastoma (GBM), remains a formidable clinical challenge. Poor immunogenicity and deficient immune infiltrates are two major limitations to an effective cancer-specific immune response. Herein, we propose that an injectable signal-amplifying nanocomposite/hydrogel system consisting of granulocyte-macrophage colony-stimulating factor and imiquimod-loaded antigen-capturing nanoparticles can simultaneously amplify the chemotactic signal of antigen-presenting cells and the "danger" signal of GBM. We demonstrated the feasibility of this strategy in two scenarios of GBM. In the first scenario, we showed that this simultaneous amplification system, in conjunction with local chemotherapy, enhanced both the immunogenicity and immune infiltrates in a recurrent GBM model; thus, ultimately making a cold GBM hot and suppressing postoperative relapse. Encouraged by excellent efficacy, we further exploited this signal-amplifying system to improve the efficiency of vaccine lysate in the treatment of refractory multiple GBM, a disease with limited clinical treatment options. In general, this biomaterial-based immune signal amplification system represents a unique approach to restore GBM-specific immunity and may provide a beneficial preliminary treatment for other clinically refractory malignancies.
