ObjectiveTo summarize and analyze the clinical characteristics of patients with acute diffuse lung changes and respiratory failure.MethodsThe clinical data of patients in the Department of Critical Care Medicine, Dazhou Central Hospital between January 2016 and December 2018 were retrospectively collected, whose main clinical manifestation was acute respiratory distress syndrome with acute onset (<3 weeks) and main imaging manifestation was diffuse changes in both lungs. The clinical characteristics of patients were summarized, and the causes of the disease were explored.ResultsA total of 65 patients with acute diffuse lung changes and respiratory failure were enrolled, including 42 males (64.6%) and 23 females (35.4%). The average age was (57.1±18.4) years, the average time from onset to treatment was (7.5±5.9) d, and the average length of stay in the intensive care unit was (8.9±4.1) d. A total of 23 cases died, with a case-fatality rate of 35.4%. Among the 65 patients, there were 50 case (76.9%) of infectious diseases, including 36 cases of bacterial infections (including 4 cases of tuberculosis), 8 cases of viral infections (all were H1N1 infections), and 6 cases of fungal infections (including 1 case of pneumocystis infection); and there were 15 cases (23.1%) of non-infectious diseases, including 4 cases of acute left heart failure, 2 cases of interstitial pneumonia, 2 cases of vasculitis, 1 case of myositis dermatomyositis, 1 case of aspiration pneumonia, 1 case of acute pulmonary embolism, 1 case of acute drug lung injury, 1 case of neurogenic pulmonary edema, 1 case of drowning, and 1 case of unknown origin.ConclusionsInfectious diseases are the main cause of acute diffuse lung changes and respiratory failure, while among non-infectious diseases, acute heart failure and immune system diseases are common causes.
ObjectiveTo investigate the association between serum thyroid hormone levels and prognosis for patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) without thyroid disease, and explore the prognostic value of serum thyroid hormone levels for patients with AECOPD.MethodsThe clinical data of 239 hospitalized cases of AECOPD [149 males, 90 females, aged 42-92 (77.7±8.9) years] from January 2013 to November 2017 were retrospectively analyzed. Serum thyroid hormone levels including total tetraiodothyronin (TT4), total triiodothyronin (TT3), thyroid stimulating hormone (TSH), free tetraiodothyronin (FT4) and free triiodothyronin (FT3) were measured by chemiluminescence immunoassay. All patients were divided into a survival group and a death group according to the prognosis. Serum thyroid hormone levels were compared between two groups. Correlations of serum thyroid hormone levels with the occurrence of death in AECOPD patients were analyzed. The prognostic value of serum thyroid hormone levels for AECOPD patients was explored by receiveroperating characteristic (ROC) curve analysis. And the best cut-off value of serum thyroid hormone level in predicting the risk of death was calculated.ResultsSerum TT4, TT3, FT4 and FT3 levels in the survival group were significantly higher than those in the death group [TT4: (89.35±21.45) nmol/L vs. (76.84±21.33) nmol/L; TT3: (1.05±0.34) nmol/L vs. (0.72±0.19) nmol/L; FT4: (16.17±2.91) pmol/L vs. (14.45±2.85) pmol/L; FT3: (3.06±0.81) pmol/L vs. (2.24±0.72) pmol/L; all P<0.05]. The differences of serum TSH level between two groups were not statistically significant [0.98 (0.54-1.83)vs. 0.57 (0.31-1.84), P>0.05]. Spearman correlation analysis showed that serum TT4, TT3, FT4 and FT3 levels were significant correlated with the occurrence of death (r values were 0.226, 0.417, 0.220, 0.387, respectively, P<0.05). And there was no significant correlation between serum TSH level and the occurrence of death (P>0.05). ROC curve analysis was done between serum thyroid hormone levels (TT4, TT3, TSH, FT4 and FT3) and the occurrence of death in the AECOPD patients. The areas under ROC curve were 0.659, 0.793, 0.588, 0.655 and 0.772, respectively. Serum TT3 was the best indicator for predicting the occurrence of death. When serum TT3 level was 0.85nmol/L, the Youden index was the highest (0.486), with a sensitivity of 70.2%, and a specificity of 78.3%. It was the best cut-offl value of serum TT3 to predict the risk of death in AECOPD patients.ConculsionsSerum thyroid hormone levels are significant associated with the prognostic for AECOPD patients. There is certain value of serum thyroid hormone levels in prognostic evaluation of AECOPD patients.
Objective To evaluate the activity of the pancreatic tissue phospholipase A2 (PLA2) in acute pancreatitis (AP) and the therapeutic effects of verapamil in rats. MethodsThe model of rat AP induced by a closed duodenal loop technique was established to observe the changes of PLA2 activity in AP group and treated group. The pancreatic histology was examined by light and electron microscopy. Results At 16 and 24 hours after induction of AP in rats, significant inhibition of the pancreatic tissue PLA2 activity was shown in the treated group as compared with AP group, with 32.34±3.87u, 35.26±4.52u and 44.83±5.31u, 47.77±5.86u respectively. The treated animals also showed a decrease in the severity of pancreatic hemorrhage, necrosis and damage to the cellular ultrastructures. Conclusion There exists high activity of PLA2 in rats AP. Calcium channel blocker, verapamil might take therapeutic effects on AP by inhibiting activity of PLA2.
Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) is defined as an acute and clinically significant respiratory deterioration characterized by evidence of new, widespread alveolar abnormality. In the past, AE-IPF was considered to be idiopathic, which was hard to be prevented and its prognosis was hard to be obviously improved; the latest researches have shown that AE-IPF can be triggered by known causes, including pulmonary infection, aspiration, etc. This review summarizes the etiology or risk factors, treatment and prevention of AE-IPF according to the latest researches.
ObjectiveTo investigate clinical efficacy of percutaneous nephroscope in treatment of patients with severe acute pancreatitis (SAP). MethodsEighty-six patients with SAP in this hospital from August 2012 to November 2015 were selected, which were divided into percutaneous nephroscope treatment group (43 cases) and laparotomy treat-ment group (43 cases) according to the difference of therapy modality. The conventional drug therapy was performed for all of them. The postoperative recovery, content of serum C reactive protein (CRP) on day 14 after operation, and post-operative complications were observed in these two groups. Results① The abdominal pain relief time, postoperative bowel sounds recovery time, normal body temperature recovery time, and postoperative hospitalization time in the percu-taneous nephroscope treatment group were significantly shorter than those in the laparotomy treatment group (P<0.05). ② The contents of serum CRP in the percutaneous nephroscope treatment group and in the laparotomy treatment group on day 14 after operation were significantly lower than those on day 1 before operation[(8.35±2.13) mg/L versus (31.44±3.45) mg/L, P<0.05; (16.42±2.44) mg/L versus (32.09±2.98) mg/L, P<0.05]. On day 14 after operation, the content of serum CRP in the percutaneous nephroscope treatment group was significantly lower than that in the laparotomy treat-ment group[(8.35±2.13) mg/L versus (16.42±2.44) mg/L, P<0.05]. ③ The incidence rate of postoperative complications in the percutaneous nephroscope treatment group was significantly lower than that in the laparotomy treatment group[14.0% (6/43) versus 32.6% (14/43), P<0.05]. ConclusionPercutaneous nephroscope in treatment of patients with SAP is effect, it has advantages of shorter hospital stay and early recovery, which could reduce incidence of postoperative complications, and it's mechanism might be related to systemic inflammatory response.
ObjectiveTo systematically review mortality risk prediction models for acute type A aortic dissection (AAAD). MethodsPubMed, EMbase, Web of Science, CNKI, WanFang Data, VIP and CBM databases were electronically searched to collect studies of mortality risk prediction models for AAAD from inception to July 31th, 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Systematic review was then performed. ResultsA total of 19 studies were included, of which 15 developed prediction models. The performance of prediction models varied substantially (AUC were 0.56 to 0.92). Only 6 studies reported calibration statistics, and all models had high risk of bias. ConclusionsCurrent prediction models for mortality and prognosis of AAAD patients are suboptimal, and the performance of the models varies significantly. It is still essential to establish novel prediction models based on more comprehensive and accurate statistical methods, and to conduct internal and a large number of external validations.
ObjectiveTo explore the correlation of serum lipocalin-2 (LCN2) with inflammation and the predictive value of LCN2 for detecting acute kidney injury (AKI) in acute pancreatitis (AP).MethodsNighty-one patients with AP, who were admitted to Bazhong Municipal Hospital of Traditional Chinese Medicine between June 2016 and June 2018, were enrolled in the present study. Clinical paramaters were analyzed between patients with AKI (n=29) and patients without AKI (n=62). The correlation of serum LCN2 with inflammation was assessed with Pearson’s correlation analysis. The area under the receiver operating characteristic curve (ROC AUC) for serum LCN2 predicting AKI in AP patients was assessed.ResultsCompared with the patients without AKI, the patients with AKI showed increased serum levels of C-reactive protein [(64.8±10.5) vs. (148.3±21.6) mg/L], procalcitonin [(3.5±2.3) vs. (4.8±3.9) μg/L], urea nitrogen [(5.5±2.1) vs. (6.6±2.8) mmol/L], creatinine [(80.3±28.1) vs. (107.3±30.8) μmol/L], interleukin-6 [(10.1±3.7) vs. (16.2±4.6) pg/mL], and LCN2 [(155.0±37.6) vs. (394.8±53.1) mg/mL], as well as decreased level of calcium [(2.6±1.3) vs. (2.0±1.0) mmol/L], the differences were all statistically significant (P<0.05). The serum level of LCN2 was correlated with C-reactive protein (r=0.694, P<0.05), interleukin-6 (r=0.762, P<0.05), and procalcitonin (r=0.555, P<0.05) in patients with AP. The ROC AUC of LCN2 for predicting AKI was 0.844 (P<0.05) , with a sensitivity of 81.3% and a specificity of 81.4% when the cut-off value was 210.2 ng/mL.ConclusionsSerum LCN2 concentration is elevated in patients with AKI. In patients with AP, serum LCN2 level is positively correlated with C-reactive protein, interleukin-6, and procalcitonin. It can be regarded as a reliable indicator for predicting AKI.
