To evaluate the process from systemic inflammatory response syndrome (SIRS) to multiple organ dysfunction syndrome (MODS) and probe the therapeutic strategies for elderly patients, we retrospectively studied the clinical data of SIRS and MODS in 292 elderly patients with surgical abdominal emergency. Results: On admission, the morbidity rate of SIRS was 41.1%. Afterwards the morbidity rate of MODS was 14.2%, and the mortality rate of the elderly patients with SIRS was 11.7%. After 48 hours of therapy, MODS was developed in 40.5% of the cases also with SIRS. Of all the 292 elderly patients, 19 cases (6.5%) developed MODS and 16 patients (84.2%) died. Conclusion: The outcome of the patients with surgical abdominal emergency may be improved if SIRS is early diagnosed, the cause of SIRS after 48 hours therapy is well defined and the body inflammatory response is properly regulated.
Objective To explore the clinical and inflammatory characteristics and risk factors of severe asthma to improve clinicians' awareness of the disease. Methods The general information of patients with asthma who visited the Department of Respiratory Medicine, the First Hospital of Shanxi Medical University from May 2018 to May 2021, as well as the diagnosis and treatment of asthma, personal history, comorbidities, auxiliary examination, asthma control test (ACT) score were collected. A total of 127 patients were included, including 40 in the severe asthma group and 87 in the mild-to-moderate asthma group. Chi-square test, independent sample t test and logistic regression were used to analyze the clinical characteristics, inflammatory markers and risk factors of severe asthma. Results Compared with the patients with mild to moderate asthma, the patients with severe asthma were more older (51.0±12.0 years vs 40.7±12.8 years, P<0.05), had more smokers (32.5% vs. 14.9%, P<0.05), and more males (67.5% vs. 40.2%, P<0.05). The patients with severe asthma got poor FEV1%pred [(56.1±23.8)% vs. (93.2±18.0)%, P<0.05] and FEV1/FVC [(56.7±13.2)% vs. (75.8±9.0)%, P<0.05)], and more exacerbations in the previous year (2.7±3.1 vs. 0.1±0.4, P<0.05), lower ACT score (14.4±3.7 vs. 18.0±5.0, P<0.05), and higher blood and induced sputum eosinophil counts [(0.54±0.44)×109/L vs. (0.27±0.32)×109/L, P<0.05; (25.9±24.2)% vs. (9.8±17.5)%, P<0.05]. There was no significant difference in the proportion of neutrophils in the induced sputum or FeNO between the two groups (P>0.05). Analysis of related risk factors showed that smoking (OR=2.740, 95%CI 1.053 - 7.130), combined with allergic rhinitis (OR=14.388, 95%CI 1.486 - 139.296) and gastroesophageal reflux (OR=2.514, 95%CI 1.105 - 5.724) were risk factors for severe asthma. Conclusions Compared with patients with mild to moderate asthma, patients with severe asthma are characterized by poor lung function, more exacerbations, and a dominant eosinophil inflammatory phenotype, which is still poorly controlled even with higher level of treatment. Risk factors include smoking, allergic rhinitis, and gastroesophageal reflux, etc.
Objective To assess the effect of nonsteroidal anti-inflammatory drugs (NSAIDs) for the prevention of colorectal neoplasia. Methods A systematic review of all relevant randomized controlled trials and quasi-randomized controlled trials of NSAIDs for prevention of colorectal neoplasms was performed by using The Cochrane Collaboration recommended methods. Results Nine trials were included and assessed. There was sufficient evidence for aspirin to prevent the development of colorectal adenomas compared with placebo in three trials of high quality and large sample size with relative risk (RR) 0.81, 95% confidence interval (CI) 0.72 to 0.91 and P=0.000 5 . No adequate evidence supported aspirin in the prevention of development of colorectal cancer (RR 0.97, 95% CI 0.79 to 1.20, P= 0.79). However, there was no evidence to support sulindac and celecoxib curing or preventing colorectal adenomas or familial adenomatous polyposis (RR 0.71, 95% CI 0.49 to 1.03, P= 0.07 and RR 0.90, 95% CI 0.76 to 1.07, P=0.23). No evidence on the dose of NSAIDs was used for prevention of colorectal adenomas at present. No significant difference was seen in the number of adverse events between patients taking NSAIDs and those taking placebo (P=0.9). Conclusions Aspirin may prevent the development of colorectal adenomas and may avoid polypectomy for 1 in every 10 to 18 persons but we don’t know whether aspirin can be substituted for endoscopically removed colorectal polyps. However, the true clinical benefit for prevention of colorectal neoplasia of NSAIDs should be considered.
ObjectiveTo investigate the association between preoperative systemic immune-inflammation index (SII) and early allograft dysfunction (EAD) in liver transplant recipients. MethodsThe patients underwent liver transplantation who met the inclusion and exclusion criteria in the West China Hospital of Sichuan University from January 2015 to December 2019 were collected. The postoperative EAD was analyzed. The generalized propensity score weighting (GPSW) were used to balance the confounding factors affecting the occurrence of EAD. ResultsA total of 390 patients who met the inclusion and exclusion criteria were enrolled in this study, 93 cases of EAD occurred, the incidence of EAD was 23.8%. The recipient’s model for endstage liver disease score and Child-Pugh grade, the donor’s body mass index, age, and graft weight, and the intraoperative cold ischemia time, liver transplantation time, intraoperative blood loss, total infusion, red blood cell transfusion, autologous blood reinfusion, fresh frozen plasma transfusion, concentrated platelet transfusion, total red blood cell and autologous blood transfusions were balanced by GPSW, then the overall mean correlation coefficient of the 14 covariables and SII decreased from 0.049 to 0.039, and each covariable reached the standard of less than 0.1. The binary logistic regression analysis based on GPSW showed that there was no significant association between SII and EAD (P=0.371). ConclusionFrom preliminary result of this study, it is not found that preoperative SII of liver transplantation patients is related to occurrence of postoperative EAD.
Atherosclerotic cardiovascular disease (ASCVD) is a disease caused by the accumulation of atherosclerotic plaques that leads to arterial hardening and impairment of contractility. Proprotein convertase subtilisin/kexin type 9 (PCSK9) can increase low-density lipoprotein cholesterol levels in plasma, which accelerates the development and progression of ASCVD. This article intends to review the biological characteristics and functional mechanisms of PCSK9, elucidate its impact on the development and progression of ASCVD, provide research literature support for the diagnosis and treatment of such diseases and improving the prognosis of patients.
Objective
To investigate the reasons, status, treatment and precautions of misdiagnosis of pulmonary inflammatory pseudotumor.
Methods
Between January 2005 and December 2015, one hundred eighteen articles about pulmonary inflammatory pseudotumor published in Wanfang and CNKI databases were retrospectively analyzed, among them forty-four articles referring to misdiagnosis rate. The misdiagnosis rate, distribute of misdiagnosed diseases, reasons and main means of definite diagnosis were analyzed.
Results
There were 1 286 cases of pulmonary inflammatory pseudotumor in the 44 articles, of them 1 012 cases were misdiagnosed. The misdiagnosis rate was 78.84%. Pulmonary inflammatory pseudotumor was often misdiagnosed as lung cancer (65.81%), tuberculosis (15.42%, which included 72 cases of tuberculoma and accounted for 7.11%) and benign pulmonary neoplasms (9.59%). Most misdiagnosed patients did not suffer from adverse consequences, except a few patients undergo unnecessary extended operations. Lack of specificity in clinical manifestations, lack of awareness about the disease, dependent on auxiliary examination and lack of awareness about the fine feature of the disease were the main reasons of misdiagnosis. The majority of misdiagnosed cases were terminal pathological diagnosed through the operation or after percutaneous biopsy.
Conclusions
Pulmonary inflammatory pseudotumor is lack of specificity in clinical manifestations and easy to be misdiagnosed. It is very important to analyze and identify the fine feature of imaging changes. To reduce and avoid misdiagnosis, clinicians should improve the awareness of this disease.
ObjectiveTo investigate the situation of depression and anxiety in the patients with postoperative inflammatory small bowel obstruction (PISBO), and to provide the dependent indications for the treatment.
MethodsThe serf-rating depression scale (SDS scale) and self-rating anxiety scale (SAS scale) were used to test the depression and anxiety of 79 patients with PISBO, who treated in the Department of General Surgery of The Second Hospital of Lanzhou from Jan. 2008 to Oct. 2014. Comparison between the scores of SDS scale/SAS scale and corresponding Chinese norms was performed, and then exploring the influence factor of depression and anxiety of PISBO patients.
ResultsThe standard scores of depression and anxiety were 49.23±11.39 and 50.31±6.25 respectively, which were higher than those of corresponding Chinese norms (P < 0.05). The results of multivariate logistic regression analysis indicated that, the independent influential factors of depression and anxiety in patients with PISBO included course of disease, type of tumor, other postoperative complications, and postoperative insomnia (P < 0.05), patients whose course of disease longer than 15 days, who with malignant tumor, and who suffered from other postoperative complications and postoperative insomnia, had higher ratios of depression and anxiety.
ConclusionThe depression and anxiety is very evident in the patients with PISBO, we should pay attention to this phenomenon and give intervention for it.
ObjectiveTo study the local vascular remodeling, inflammatory response, and their correlations following acute spinal cord injury (SCI) with different grades, and to assess the histological changes in SCI rats.MethodsOne hundred and sixteen adult female Sprague Dawley rats were randomly divided into 4 groups (n=29). The rats in sham group were received laminectomy only. A standard MASCIS spinal cord compactor was applied with drop height of 12.5, 25.0, or 50.0 mm to establish the mild, moderate, or severe SCI model, respectively. Quantitative rat endothelial cell antigen 1 (RECA1) and CD68 positive areas and the correlations were studied by double immunofluorescent (DIF) staining at 12 hours, 24 hours, 3 days, 7 days, and 28 days following SCI. Moreover, qualitative neurofilament-H (NF-H) and glial fibrillary acidic protein (GFAP) positive glial cells were studied by DIF staining at 28 days. ELISA was used to detect the levels of tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β), and IL-6 in spinal cord homogenates at 12 hours, 24 hours, and 3 days, and the correlations between TNF-α, IL-1β, or IL-6 levels and microvascular density (RECA1) were accordingly studied. Moreover, the neural tissue integrity and neuron damage were assessed by HE staining at 12 hours, 24 hours, 3 days, 7 days, and 28 days, and Nissl’s staining at 28 days following SCI, respectively.ResultsDIF staining revealed that the ratio of RECA1 positive area was the highest in moderate group, higher in mild and severe groups, and the lowest in sham group with significant differences between groups (P<0.05). The ratio of CD68 positive area was the highest in severe group, higher in moderate and mild groups, and the lowest in sham group with significant differences between groups (P<0.05), except the comparisons between mild and moderate groups at 24 hours and 28 days after SCI (P>0.05). There was no significant correlation between the RECA1 and CD68 expressions in sham group at different time points (P>0.05). At 12 and 24 hours after SCI, the RECA1 and CD68 expressions in mild and moderate groups showed significant positive correlations (P<0.05), while no significant correlation was found in severe group (P>0.05). No significant correlations between the RECA1 and CD68 expressions was shown in all SCI groups at 3 days and in severe group at 7 days (P>0.05), while the negative correlations were shown in mild and moderate groups at 7 days, and in all SCI groups at 28 days (P<0.05). In mild, moderate, and severe groups, the axons became disrupted, shorter and thicker rods-like, or even merged blocks with increased injury, while the astrocytes decreased in number, unorganized and condensed in appearance. ELISA studies showed that TNF-α, IL-1β, and IL-6 levels in sham group were significantly lower than those in other 3 groups at different time points (P>0.05). The differences in TNF-α, IL-1β, and IL-6 levels between SCI groups at different time points were sinificant (P<0.05), except IL-1β levels between the mild and moderate groups at 12 hours (P>0.05). Three inflammatory factors were all significantly correlated with the microvascular density grades (P<0.05). Histological analysis indicated that the damage to spinal cord tissue structure correlated with the extent of SCI. In severe group, local hemorrhage, edema, and infiltration of inflammatory cells were found the most drastic, the grey/white matter boundary was disappeared concurrently with the formation of cavity and shortage of normal neurons.ConclusionIn the acute stage following mild or moderate SCI, progressively aggravated injury result in higher microvessel density and increased inflammation. However, at the SCI region, the relation between microvessel density and inflammation inverse with time in the different grades of SCI. Accordingly, the destruction of neural structures positively relate to the grades of SCI and severity of inflammation.
Rituximab (RTX) is a monoclonal antibody directed against the CD20 antigen expressed on B cells. It has been successfully employed in the treatment of non-Hodgkin's lymphoma and varied systemic autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, and granulomatosis with polyangiitis. Recently its efficacy in the treatment of ocular inflammatory diseases (OID), including refractory scleritis, peripheral ulcerative keratitis, uveitis, and ocular cicatricial pemphigoid, has aroused more concerns. The literature suggests that RTX may be useful for controlling the inflammation and decreasing or stopping the use of corticosteroids and other immunosuppressants in OID, which may contribute a new treatment alternative in patients with the recalcitrant and sight-threatening forms of OID. This article reviews the clinical application status of RTX in the treatment of OID.
ObjectiveTo explore the combined application of neutrophil to lymphocyte ratio (NLR) and systemic immune inflammation index (SII) on the prognosis of hepatitis B-related hepatocellular carcinoma after resection.MethodsRetrospectively collected data of 180 patients with hepatitis B-related hepatocellular carcinoma who were hospitalized in the Department of Infectious Diseases and Hepatobiliary Surgery of the Affiliated Hospital of Southwest Medical University and received surgical treatment from January 2013 to December 2019, including general information, laboratory examination and abdominal CT or MRI results. NLR and SII values were measured at one week before operation, and their critical values of NLR and SII were determined by ROC curve analysis. Univariate and multivariate analysis were performed to determine the risk factors to predict the survival status of patients with hepatitis B-related hepatocellular carcinoma after hepatectomy.ResultsUnivariate analysis showed that AFP, platelets, TNM staging, portal vein tumor thrombus, tumor differentiation, NLR, SII, and NLR+SII combined score were significantly correlated with the prognosis of patients with hepatitis B-related hepatocellular carcinoma (P<0.05). Multivariate analysis showed that PLT [HR=1.791, 95%CI (1.124, 2.854), P=0.014], NLR [HR=4.289, 95%CI (2.571, 7.156), P<0.001], SII [HR=5.317, 95%CI (3.016, 9.374), P<0.001], and NLR+SII combined score [HR=7.901, 95%CI (4.124, 15.138), P<0.001] were independently correlated with the survival of patients with hepatitis B-related hepatocellular carcinoma.ConclusionsThe preoperative NLR+SII combined score can be used to evaluate the postoperative prognosis of patients with hepatitis B-related hepatocellular carcinoma. The higher the score, the lower the postoperative survival rate.
