Objective To investigate the expression of Th17 cells in peripheral blood of patients with sarcoidosis at different stage. Methods Flow cytometry was used to detect the Th17 cells in peripheral blood of 38 patients with sarcoidosis, including 18 cases of newly diagnosed active patients with obvious symptoms such as cough, fever, fatigue and weight loss, and 20 stable cases who were followed up regularly.15 cases of healthy volunteers were enrolled as control. Serumangiotensin-converting enzyme ( SACE) of the patients with sarcoidosis was detected by ultraviolet spectrophotometry. The cell classification and CD4 + /CD8 + T in the BALF of the newly diagnosed active patients were calculated. Results The expression of Th17 cells in peripheral blood in the patients with active sarcoidosis were higher than that in the sable patients and the controls [ ( 1. 59 ±0. 44) % vs. ( 0. 56 ±0. 32) % and ( 0. 49 ±0. 23) % , all P lt; 0. 05] . Th17 cells in peripheral blood in the patients with stable sarcoidosis and the controls were not different significantly ( P gt;0. 05) . The levels of SACE in the patients with active sarcoidosis were higher than that in the patients with stable sarcoidosis [ ( 56. 6 ±14. 6) IU/L vs. ( 35. 8 ±18. 3) IU/L, P lt; 0. 05) . There was not significant correlation between the Th17 cells in peripheral blood and SACE in the patients with sarcoidosis ( P gt;0. 05) . In the patients with active sarcoidosis, the Th17 cells in peripheral blood were not significantly correlated with lymphocyte percentages in BALF( P gt; 0. 05) , but significantly correlated with CD4 + /CD8 + in BALF ( r=0. 63, P lt;0. 05) .Conclusion In patients with active sarcoidosis, the increased expression of Th17 cells in peripheral blood may correlate with the activity of sarcoidosis.
Non-alcoholic fatty liver disease (NAFLD) is one of the major chronic liver diseases that endanger human health. It is characterized by hepatic steatosis and absence of other causes of hepatic fat accumulation, such as alcohol abuse. The incidence of NAFLD is increasing year by year. However, the pathogenesis is still undefined. Porphyromonas gingivalis is a major periodontal pathogen of various periodontal disease. Apart from affecting periodontal health, Porphyromonas gingivalis is also related to the incidence of many systemic diseases. In recent years, Porphyromonas gingivalis is considered to be a risk factor of NAFLD. In this paper, the relationship between NAFLD and Porphyromonas gingivalis, as well as the possible pathogenesis are discussed.
Surgery is an accepted standard in the treatment of adenocarcinoma of esophagogastric junction (AEG), but the efficacy of surgery alone for locally advanced AEG is limited. In-depth studies concerning combined therapy for AEG have been carried out worldwide, including neoadjuvant chemotherapy (nCT), neoadjuvant chemoradiotherapy (nCRT), perioperative chemotherapy (pCT), postoperative chemoradiotherapy, etc. Significantly, the contribution of nCRT and pCT to improving the prognosis of locally advanced AEG patients has been shed light on. Compared with that, multimodality treatment for AEG patients is not well established in China. An attempt was thus made to take an overview of the evidence-based research advance regarding integrated therapy of AEG.
Objective To systematically review the abroad studies on patients for patient safety, and compare them with the current status of domestic studies, so as to provide suggestions for evidence-based strategic decision about how to conduct the education of patients for patient safety and improve the medical quality. Methods The databases of MEDLINE, EMbase and Chinese Biomedical Literature Database (CBM) were searched to identify the relevant studies and their references. Literatures were screened with data extraction in accordance with the predefined inclusive and exclusive criteria. The quality of literatures was assessed with the standard of Cochrane Handbook 5.0 and Critical Appraisal Skills Programme, and the data were comprehensively analyzed with qualitative research methods.Results Among 28 included studies, 5 were Chinese literatures, 1 was RCT, and the others were cross-sectional studies. The results showed that: a) Generally, the patients at home and abroad were poor in the awareness of patient safety, but they were eager to participate in the patient safety; b) Factors affecting patients’ participation were their characteristics, disease-related, and emotional feelings; c) Three studies reported the methods of involving patients in patient safety from the aspects of infection, malpractice, and medication; d) Some studies showed that patients’ participation could effectively promote the standardized operation of medical staffs, prevent unsafe events, and reduce damages; and e) The research contents of the included Chinese literatures were just related to the patients’ awareness of patient safety, attitude to participation, and influencing factors. Conclusion The limited studies relevant to patients for patient safety are short of high-quality RCTs for proving the effectiveness of patient participation methods, so it indicates that the stress should be laid on evaluating the effectiveness of patients for patient safety in future research.
【Abstract】 Objective To compare the accuracy of color-doppler ultrasonography, mammography and near-infrared light scanning for diagnosing breast diseases. Methods The diagnostic accuracy of the above three imaging methods were analyzed and compared with each other on the basis of the postoperative pathological results. ResultsFive hundreds and sixty-five cases (breast cancer: 274 cases, benign diseases: 291 cases) were examined. The sensitivity of color-doppler ultrasonography, mammography and near-infrared light scanning for diagnosing breast cancer were 83.7%(200/239), 84.2%(64/76) and 76.9%(100/130), respectively. The specificity were 88.6%(226/255), 93.2%(69/74) and 82.6%(114/138), and the accuracy were 86.2%(426/494), 88.7%(133/150) and 79.9%(214/268), respectively. Color-doppler ultrasonography and mammography were superior to near-infrared light in the item of accuracy (P＜0.05), especially for lesions of breast cancers that were less than 2 cm. The false negative rate of near-infrared light was higher (48.8%, 21/43）than those of the other methods in detecting breast cancer at early stage. The sensitivity for detecting intraductal papilloma and inflammation of breast using color-doppler ultrasonography were 58.8%(10/17) and 69.2%(18/26), respectively, which were higher than that of near-infrared light scanning 〔0 and 23.5%(4/17)， P＜0.05 and P＜0.01〕. The sensitivity and the accuracy of near-infrared light without physical examination reduced significantly, in which the sensitivity reduced from 76.9%(100/130) to 56.9%(74/130), P＜0.01, and the accuracy reduced from 79.9%(214/298) to 61.9%(166/268), P＜0.01. Conclusion Color-doppler ultrasonography and mammography are accurate imaging methods for diagnosing breast diseases.
Objective To investigate the clinical characteristics and bacterial drug resistance of bloodstream infection of gram-negative bacteria, and provide guidance for clinical rational drug use and control of hospital infection. Methods A retrospective analysis was conducted in the patients diagnosed as severe pneumonia with blood culture of gram-negative bacteria from January 2015 to December 2017 in Beijing Anzhen Hospital. Results A total of 60 severe pneumonia patients suffered from bloodstream infection of gram-negative bacteria were recruited including 34 males and 26 females aging from 42 to 89 years and 73.4 years in average. In the 60 patients, 32 cases were infected with Klebsiella pneumonias, 20 cases were infected with Acinetobacter baumanni, and 8 cases were infected with Escherichia coli. The antimicrobial susceptibility testing result of Klebsiella pneumonias showed that the drug susceptibility rate was 100% to tigecycline, and 6.3% to amikacin. Escherichia coli was sensitive to Amikacin, imipenem, ceftazidime and meropenem while resistance to other drugs. The antimicrobial resistance of Acinetobacter baumanni was 28.6% for cefoperazone/sulbactam, and 14.3% for tigecycline. C-reactive protein, procalcitonin and SOFA scores were higher in the patients infected with Acinetobacter baumanni. Neutrophils and blood lactic acid were higher in the patients infected with Klebsiella pneumonias. There were no statistical differences in white blood cell, platelet or motality rate between the patients infected with Acinetobacter baumanni and the patients infected with Klebsiella pneumonias. SOFA scores and blood lactic acid had significantly statistical relevance with prognosis. Conclusion There is a high proportion of drug resistance of Klebsiella pneumoniae and Acinetobacter baumanni in the bloodstream infection of gram-negative bacteria.
ObjectiveTo study the correlation between international normalized ratio (INR) and coagulation factor Ⅱ and Ⅹ in patients with pulmonary thromboembolism treated with warfarin at moderate and low intensity anticoagulation.MethodsFifty-one patients with pulmonary thromboembolism treated with warfarin orally were divided into low-intensity anticoagulation group (INR from 1.6 to 2.0) and standard-intensity anticoagulation group (INR form 2.0 to 3.0) according to their monitoring INR indices. The levels of coagulation factor Ⅱ and Ⅹ were measured, and the correlation between INR level and coagulation factor activity was compared.ResultsThe INR of the low intensity anticoagulation group was 1.69±0.2 and the standard intensity anticoagulation group was 2.55±0.46. The corresponding activity of coagulation factor Ⅱ was (48.3±28.0)% and (24.0±8.0)% respectively. The activity of coagulation factor Ⅹ was (32.8±24.0)% and (16.7±6.0)%. There was a negative correlation between the activity of INR and coagulation factor Ⅱ and Ⅹ, with correlation coefficients of –0.903 and –0.459, respectively. Coagulation factor Ⅱ activity < 40%, coagulation factor Ⅹ activity inhibitory level < 25% is defined as anticoagulation effect. When coagulation factor Ⅱ activity level reaches anticoagulation effect, the corresponding minimum INR value was 1.56 and as to coagulation factor Ⅹ, the corresponding minimum INR value was 1.66.ConclusionsINR is negatively correlated with the activity of coagulation factor Ⅱ and coagulation factor Ⅹ. With the increase of INR, the activity of coagulation factor Ⅱ and coagulation factor Ⅹ decrease. Low intensity anticoagulation could not effectively inhibit the activity of coagulation factor.
Objective To understand the preventive effect of pneumatic compression therapy on deep vein thrombosis (DVT) in lower limbs of patients with spinal cord injury. Methods Patients with spinal cord injury who transferred from Orthopedics Department to Rehabilitation Department undergoing rehabilitation in the First Affiliated Hospital of University of Science and Technology of China and discharged from April 2017 to December 2020 were retrospectively included. According to the contents of the medical order of the case data, the patients were divided into treatment group and control group. The intervention method of the treatment group was pneumatic compression therapy and conventional rehabilitation treatment, and the control group was conventional rehabilitation treatment. Multivariate logistic regression was used for statistical analysis to explore the association of pneumatic compression therapy and the risk of DVT in patients with spinal cord injury. Results Finally, 153 patients were enrolled, including 71 cases in the treatment group and 82 cases in the control group. After rehabilitation therapy, DVT occurred in 10 cases (14.1%) in the treatment group and 21 cases (25.6%) in the control group. There was no significant difference in incidence of DVT between the two groups (χ2=3.129, P=0.077). After six months of follow-up, DVT occurred in 11 cases (15.5%) in the treatment group and 12 cases (14.6%) in the control group. There was no significant difference in incidence of DVT between the two groups (χ2=0.022, P=0.822). D-dimer [odds ratio (OR) =1.104, 95% confidence interval (CI) (1.036, 1.175), P=0.002] and age [OR=1.081, 95%CI (1.040, 1.124), P<0.001] were independent risk factors for the risk of DVT after treatment. Pneumatic compression therapy was a protective factor for the risk of DVT [OR=0.210, 95%CI (0.075, 0.591), P=0.003]. Age [OR=1.057, 95%CI (1.008, 1.108), P=0.023] was an independent risk factor for the risk of DVT after six months. The effect of pneumatic compression therapy was not statistically significant (P=0.393). Conclusions After spinal cord injury, it is necessary to strengthen the management of high serum D-dimer state, especially the risk of DVT in elderly patients. Pneumatic compression therapy could be used as a treatment measure to reduce risk of DVT in patients with spinal cord injury during hospitalization, however, the preventive effect after half a year needs to be further studied.
ObjectiveGelatin methacryloyl (GelMA)/hyaluronic acid methacryloyl (HAMA)/chitosan oligosaccharide (COS) hydrogel was used to construct islet biomimetic microenvironment, and to explore the improvement effect of GelMA/HAMA/COS on islet activity and function under hypoxia. Methods Islets cultured on the tissue culture plate was set as the control group, on the GelMA/HAMA/COS hydrogel with COS concentrations of 0, 1, 5, 10, and 20 mg/mL respectively as the experimental groups. Scanning electron microscopy was used to observe the microscopic morphology, rheometer test to evaluate the gel-forming properties, contact angle to detect the hydrophilicity, and the biocompatibility was evaluated by the scaffold extract to L929 cells [using cell counting kit 8 (CCK-8) assay]. The islets were extracted from the pancreas of 8-week-old Sprague Dawley rats and the islet purity and function were identified by dithizone staining and glucose-stimulated insulin secretion (GSIS) assays, respectively. Islets were cultured under hypoxia (1%O2) for 24, 48, and 72 hours, respectively. Calcein-acetyl methyl/propidium iodide (Calcein-AM/PI) staining was used to evaluate the effect of hypoxia on islet viability. Islets were cultured in GelMA/HAMA/COS hydrogels with different COS concentrations for 48 hours, and the reactive oxygen species kits were used to evaluate the antagonism of COS against islet reactive oxygen species production under normoxia (20%O2) and hypoxia (1%O2) conditions. Calcein-AM/PI staining was used to evaluate the effect of COS on islet activity under hypoxia (1%O2) conditions. Islets were cultured in tissue culture plates (group A), GelMA/HAMA hydrogels (group B), and GelMA/HAMA/COS hydrogels (group C) for 48 hours, respectively. Immunofluorescence and GSIS assays were used to evaluate the effect of COS on islet activity under hypoxia (1%O2) conditions, respectively. Results GelMA/HAMA/COS hydrogel had a porous structure, the rheometer test showed that it had good gel-forming properties, and the contact angle test showed good hydrophilicity. CCK-8 assay showed that the hydrogel in each group had good biocompatibility. The isolated rat islets were almost round, with high islet purity and insulin secretion ability. Islets were treated with hypoxia for 24, 48, and 72 hours, Calcein-AM/PI staining showed that the number of dead cells gradually increased with time, which were significantly higher than those in the non-hypoxia-treated group (P<0.001). Reactive oxygen staining showed that GelMA/HAMA/COS hydrogels with different COS concentrations could antagonize the production of reactive oxygen under normal oxygen and hypoxia conditions, and this ability was positively correlated with COS concentration. Calcein-AM/PI staining indicated that GelMA/HAMA/COS hydrogels with different COS concentrations could improve islet viability under hypoxia conditions, and cell viability was positively correlated with COS concentration. Immunofluorescence staining showed that GelMA/HAMA/COS hydrogel could promote the expression of islet function-related genes under hypoxia conditions. GSIS assay results showed that the insulin secretion of islets in hypoxia condition of group C was significantly higher than that of groups B and C (P<0.05). Conclusion GelMA/HAMA/COS hydrogel has good biocompatibility, promotes islet survival and function by inhibiting reactive oxygen species, and is an ideal carrier for building islet biomimetic microenvironment for islet culture and transplantation.
