ABSTRACT
Objective:To construct a risk prediction model for infection with Klebsiella pneumonia (KP) for patients with severe acute pancreatitis (SAP).Methods:Retrospective analysis was done on the clinical data of 109 SAP patients who were admitted to Shanghai General Hospital, between March 2016 and December 2021. Patients were classified into infection group ( n=25) and non-infection group ( n=84) based on the presence or absence of KP infection, and the clinical characteristics of the two groups were compared. The least absolute shrinkage and selection operator (LASSO) algorithm was used to reduce the dimension of the variables with statistical significance in univariate analysis. A nomogram prediction model was created by incorporating the optimized features from the LASSO regression model into the multivariate logistic regression analysis. Receiver operating characteristic curve (ROC) was drawn and the area under curve (AUC) was calculated; and consistency index (C-index) were used to assess the prediction model's diagnostic ability. Results:A total of 25 strains of KP were isolated from 109 patients with SAP, of which 21(84.0%) had multi-drug resistance. 20 risk factors (SOFA score, APACHEⅡ score, Ranson score, MCTSI score, mechanical ventilation time, fasting time, duration of indwelling of the peritoneal drainage tube, duration of deep vein indwelling, number of invasive procedures, without or with surgical intervention, without or with endoscopic retrograde cholangiopancreatography (ERCP), types of high-level antibiotics used, digestion disorders, abnormalities in blood coagulation, metabolic acidosis, pancreatic necrosis, intra-abdominal hemorrhage, intra-abdominal hypertension, length of ICU stay and total length of hospital stay) were found to be associated with KP infection in SAP patients by univariate analysis. The four variables (APACHEⅡ score, duration of indwelling of the peritoneal drainage tube, types of high-level antibiotics used, and total length of hospital stay) were extracted after reduced by LASSO regression. These four variables were found to be risk factors for KP infection in SAP patients by multiple logistic regression analysis (all P value <0.05). Nomogram prediction model for KP infection in SAP was established based on the four variables above. The verification results of the model showed that the C-index of the model was 0.939, and the AUC was 0.939 (95% CI 0.888-0.991), indicating that the nomogram model had relatively accurate prediction ability. Conclusions:This prediction model establishes integrated the basic clinical data of patients, which could facilitate the risk prediction for KP infection in patients with SAP and thus help to formulate better therapeutic plans for patients.
ABSTRACT
Objective:To investigate the effect of T-lymphocyte and subpopulation counts on the prognosis of severe acute pancreatitis (SAP) patients.Methods:The clinical data of 90 patients with SAP diagnosed at the Shanghai General Hospital between January 2019 and June 2022 were retrospectively analyzed, and the patients were divided into good prognosis and poor prognosis group according to whether they were diagnosed for 28 d. The general information of the patients was recorded, including blood-related immunological indicators within 24 h of diagnosis, including leukocytes, neutrophils, lymphocytes, monocytes, CD 3+ , CD 4+ , CD 8+ T-lymphocyte count and CD 4+ /CD 8+ T-lymphocyte ratio, IgG4 level; blood inflammation index procalcitonin, albumin level and APACHEⅡ score at admission; survival and complication status of patients at 28 d of diagnosis. Non-parametric Mann-Whitney U test was used to analyze the correlation between each index and the prognosis of the patients. The subject operating characteristic curve (ROC) of patients was plotted, and area under curve (AUC) was calculated to assess the value of CD 3+ and CD 4+ T-lymphocytes in predicting the prognosis of SAP. Results:The majority of SAP patients were male (65.6%). The main cause of SAP was gallstone (56.7%), followed by hyperlipidemia (35.6%). At 28 days after diagnosis, 85(94.4%) patients survived, and 39 of them were cured and included in the good prognosis group. Forty-six cases were complicated with infection, multiple organ dysfunction syndrome (MODS) and local pancreatic complications, and 5 cases (5.56%) died; and a total of 51 cases were included in the poor prognosis group. Compared with the good prognosis group, the number of CD 3+ T-lymphocytes [366(268, 498) cells /μl vs 709(578, 999) cells /μl], CD 4+ T-lymphocytes [209(120, 298) cells /μl vs 486(303, 548) cells /μl] and albumin level (33.9 g/L vs 35.9 g/L) within 24 hours in the poor prognosis group were significantly lower, while the level of procalcitonin (1.02 ng/ml vs 0.43 ng/ml) and APACHEⅡ score [7(4, 10) vs 5(3, 8)] were significantly increased, and all the differences were statistically significant (all P value <0.05). ROC curve analysis showed that the AUC values for CD 3+ and CD 4+ T-lymphocyte counts within 24 hours for predicting poor prognosis of SAP were 0.857 (95% CI 0.696-1.000) and 0.867 (95% CI 0.708-1.000), respectively. The cut-off values were 524 cells /μl and 301 cells /μl, the sensitivity were both 85.7%, and the specificity were 78.6% and 85.7%, respectively. Conclusions:The significant decrease of peripheral blood CD 3+ and CD 4+ T-lymphocyte count within 24 h of SAP diagnosis has a certain predictive value for the prognosis of patients with SAP.
ABSTRACT
Objective:To evaluate the clinical efficacy of continuous renal replacement therapy (CRRT) with adsorptive filter oXiris in the treatment of severe acute pancreatitis (SAP).Methods:The clinical data of 5 SAP patients who received the treatment of absorptive filter oXiris in Department of Critical Care Medicine of Shanghai General Hospital from February 2021 to February 2022 were collected. The changes of inflammatory indicators, hemodynamics, acid-base balance indicators and organ function indicators were compared before and 24 h after treatment.Results:Before the treatment of oXiris, 3 patients had pancreatic necrotic infection, and all the five patients had systemic inflammatory response syndrome(SIRS), acute respiratory and circulatory failure and acute renal injury. At 24 h after the treatment with oXiris, the levels of inflammatory indicators such as white blood cell count [(13.4±5.0)×10 9/L vs (25.8±10.0)×10 9/L), CRP [(149.6±68.3)mg/L] vs (289.0±129.4)mg/L] and procalcitonin [3.7(1.4, 17.7)ng/ml vs 12.2(3.2, 62.9)ng/ml] in the blood samples from the patients were greatly decreased. Hemodynamics were obviously improved; heart rate [(107.4±9.5)bpm/min vs (143.4±9.7)bpm/min] was decreased, and the mean artery pressure [(87±5)mmHg vs (73±13)mmHg], 1 mmHg=0.133 kPa] tended to be stabilized. Metabolic acidosis was significantly improved; pH value (7.4±0.0 vs 7.2±0.1) and base excess (-2.1±2.5 vs -14.5±6.1) were increased, while lactic acid [(2.6±1.2)mmol/L vs (10.62±6.55)mmol/L] was decreased. Organ dysfunctions were improved; PaO 2/FiO 2 value (241.7±58.5 vs 115.9±53.6) was increased, while serum creatinine [(148.0±42.5)μmol/L vs (232.8±77.4)μmol/L], intra-abdominal pressure [(18.6±4.5)mmHg vs (24.2±4.0)]mmHg, modified Marshall score [3(3.0, 4.0) vs 6(5.5, 9.0)] and APACHEⅡ score (17.6±2.9 vs 26.0±5.2) were decreased. All the differences above were statistically significant (all P value <0.05). Conclusions:It is safe and feasible to treat SAP patients with CRRT by using oXiris in clinical practice, which may have the functions of clearing inflammatory mediators, stabilizing hemodynamics and acid-base balance and improving organ function.
ABSTRACT
Objective:To analyse the clinical efficacy and outcome of early abdominal paracentesis drainage (APD) in the treatment of severe acute pancreatitis (SAP).Methods:The clinical data of 107 SAP patients with massive abdominal fluid in Shanghai General People Hospital from May 2017 to December 2021 were collected and analyzed. Patients were divided into APD group ( n=56) and NO-APD group ( n=51) according to whether they underwent APD or not within 3 days after admission. The APD group was then divided into abdominal compartment syndrome (ACS) subgroup ( n=29) and NO-ACS subgroup ( n=27) according to whether ACS had occurred or not at the time of puncture. Patients' general data, the duration of systemic inflammatory response (SIRS), length of ICU stay, the trends of intra-abdominal pressure and inflammatory indicators (white blood cell count and the content of C-reactive protein) within 1-3 days after admission, incidence of infection complication, step-up therapy, discharge or death were recorded. Results:The intra-abdominal pressure were 18.6±5.6mmHg , 13.7±4.2mmHg (1 mmHg=0.133 kpa) in APD group and NO-APD group, respectively. The intra-abdominal pressure of APD group was significantly higher than that of NO-APD group, and the difference was statistically significant ( P=0.000). Compared with NO-APD group, the duration of SIRS was significantly shortened in APD group [3(2, 4) days vs 4(3, 6) days, P=0.029]. On day 1, 2 and 3 after admission, the intra-abdominal pressure was 18.6±5.6 mmHg, 16.4±4.7 mmHg and 13.5±3.9 mmHg in APD group, and was 13.7±4.2 mmHg, 12.3±3.6 mmHg and 11.0±2.6 mmHg in NO-APD group, respectively. The intra-abdominal pressure of the APD group dropped faster than the NO-APD group ( P=0.004). The white blood cell count was (14.8±4.8), (10.5±4.5) and (9.0±3.8)×10 9/L in APD group, and was (14.2±5.4), (12.3±7.3), (11.7±5.3)×10 9/L in NO-APD group, respectively. Compared with the NO-APD group, the decrease rate of white blood cell count was faster in APD group ( P=0.006). The C-reactive protein content was (153.6±47.1), (150.4±10.5) and (108.8±49.4)mg/L in APD group, and were (174.8±31.1), (191.6±29.4) and (186.8±45.5)mg/L in NO-APD group . The content of C-reactive protein in APD group decreased significantly, while that in NO-APD group did not decrease. There was a significant difference between the two groups ( P=0.009). In the subgroup comparisons, the duration of SIRS in the ACS subgroup was significant longer than that in the NO-ACS subgroup [4(3, 5) days vs 2(1, 3)days, P=0.000]. Compared between the two groups and two subgroups respectively, there were no statistically significant differences on length of ICU stay, infection complication rate, advanced treatment rate and mortality. Conclusions:For SAP patients with abdominal fluid, APD in the early stage could shorten the duration of SIRS, decrease intra-abdominal pressure rapidly, improve inflammatory indicators, but could not improve the clinical outcome.
ABSTRACT
Background: Autoimmune gastritis (AIG) can lead to hypergastrinemia and enterochromaffin ⁃ like cell hyperplasia, thereby increasing the risk of gastric neuroendocrine neoplasms and gastric adenocarcinoma. However, research on the association between AIG and gastric polyps is limited. Aims: To investigate the risk factors for the development of gastric polyps in AIG patients. Methods: The clinical data of 103 AIG patients visited the Chinese People’s Armed Police Force Sichuan Provincial Corps Hospital from June 2019 to June 2023 was collected retrospectively. The parameters analyzed included gender, age, anti⁃parietal cell antibody, anti⁃intrinsic factor antibody, pepsinogen (PG)I, PGII, ratio for PGI/ II, gastrin ⁃ 17 (G ⁃ 17), OLGA and OLGIM staging, size, location and pathological types of gastric polyps, vitamin B12, Helicobacter pylori infection and presence of anemia at the year AIG diagnosed. Univariate and multivariate Logistic regression analyses were performed to identify the risk factors for gastric polyps in AIG patients. The predictive performance of the variables was assessed by ROC curve analysis. Results: Among the 103 AIG patients enrolled in the study, 67 (65.05%) were females, and the median age was 58 years old. Fourteen (13.59%) patients had gastric polyps. Compared to patients without gastric polyps, those with gastric polyps had significantly higher levels of serum G ⁃ 17 (P< 0.000 1). Multivariate Logistic regression analysis indicated that G⁃ 17 was an independent risk factor for gastric polyps in AIG patients (OR=1.047, 95% CI: 1.017 ⁃ 1.078, P=0.002). The area under the curve (AUC) of G ⁃ 17 and the Logistic regression model in predicting the gastric polyp formation in AIG patients was 0.811 and 0.884, respectively. The optimal cutoff value of G⁃17 was 69.50 pmol/L, with the sensitivity and specificity of 92.9% and 67.4%, respectively. Conclusions: Serum G⁃17 is a potential prognostic factor for AIG. The optimal cutoff value for predicting the development of gastric polyp is 69.50 pmol/L.
ABSTRACT
Objective:To compare and analyze the clinical features of patients with severe coronavirus disease 2019 (sCOVID-19) and severe community acquired pneumonia (sCAP) who meet the diagnostic criteria for severe pneumonia of the Infectious Diseases Society of America/American Thoracic Society (IDSA/ATS).Methods:A retrospective comparative analysis of the clinical records of 116 patients with sCOVID-19 admitted to the department of critical care medicine of Wuhan Third Hospital from January 1, 2020 to March 31, 2020 and 135 patients with sCAP admitted to the department of critical care medicine of Shanghai First People's Hospital from January 1, 2010 to December 31, 2017 was conducted. The basic information, diagnosis and comorbidities, laboratory data, etiology and imaging results, treatment, prognosis and outcome of the patients were collected. The differences in clinical data between sCOVID-19 and sCAP patients were compared, and the risk factors of death were analyzed.Results:The 28-day mortality of sCOVID-19 and sCAP patients were 50.9% (59/116) and 37.0% (50/135), respectively. The proportion of arterial partial pressure of oxygen/fraction of inspired oxygen (PaO 2/FiO 2)≤250 mmHg (1 mmHg ≈ 0.133 kPa) in sCOVID-19 patients was significantly higher than that of sCAP [62.1% (72/116) vs. 34.8% (47/135), P < 0.01]. The possible reason was that the proportion of multiple lung lobe infiltration in sCOVID-19 was significantly higher than that caused by sCAP [94.0% (109/116) vs. 40.0% (54/135), P < 0.01], but the proportion of sCOVID-19 patients requiring mechanical ventilation was significantly lower than that of sCAP [45.7% (53/116) vs. 60.0% (81/135), P < 0.05]. Further analysis of clinical indicators related to patient death found that for sCOVID-19 patients PaO 2/FiO 2, white blood cell count (WBC), neutrophils (NEU), neutrophil percentage (NEU%), neutrophil/lymphocyte ratio (NLR), total bilirubin (TBil), blood urea nitrogen (BUN), albumin (ALB), Ca 2+, prothrombin time (PT), D-dimer, C-reactive protein (CRP) and other indicators were significantly different between the death group and the survival group, in addition, the proportion of receiving mechanical ventilation, gamma globulin, steroid hormones and fluid resuscitation in death group were higher than survival group. Logistic regression analysis showed that the need for mechanical ventilation, NLR > 10, TBil > 10 μmol/L, lactate dehydrogenase (LDH) > 250 U/L were risk factors for death at 28 days. For sCAP patients, there were significant differences in age, BUN, ALB, blood glucose (GLU), Ca 2+ and D-dimer between the death group and the survival group, but there was no significant difference in treatment. Logistic regression analysis showed that BUN > 7.14 mmol/L and ALB < 30 g/L were risk factors for 28-day death of sCAP patients. Conclusions:The sCOVID-19 patients in this cohort have worse oxygen condition and symptoms than sCAP patients, which may be due to the high proportion of lesions involving the lungs. The indicators of the difference between the death group and the survival group were similar in sCOVID-19 and sCAP patients. It is suggested that the two diseases have similar effects on renal function, nutritional status and coagulation function. But there were still differences in risk factors affecting survival. It may be that sCOVID-19 has a greater impact on lung oxygenation function, inflammatory cascade response, and liver function, while sCAP has a greater impact on renal function and nutritional status.
ABSTRACT
Objective:To evaluate the effect of thymosin alpha 1 on the prognosis of patients with coronavirus disease 2019 (COVID-19).Methods:A retrospective cohort study was performed to collect clinical data of 95 patients treated by Shanghai Aid Medical Team in Wuhan Third Hospital during January 31, 2020 and March 4, 2020, who were confirmed COVID-19. They were divided into two groups according to whether they were treated with thymosin alpha 1 after admission. The 28-day mortality (primary outcome), and 28-ventilator-free-day, lymphocyte count (LYM) level, C-reactive protein (CRP) level (secondary outcomes) were compared between two groups. Survival analysis was performed using the Kaplan-Meier curve. The effect of thymosin alpha 1 on 28-day survival was evaluated with Cox regression model.Results:Among the 95 patients, there were 31 cases in thymosin group and 64 cases in non-thymosin group; 29 patients died 28 days after admission, including 11 cases (35.5%) in thymosin group and 18 cases (28.1%) in non-thymosin group. Kaplan-Meier survival curve showed that thymosin alpha 1 could improve the 28-day survival of patients with COVID-19, but the univariate Cox model analysis showed that the difference was not statistically significant [hazard ratio ( HR) = 0.48, 95% confidence interval (95% CI) was 0.20-1.14, P = 0.098]; multivariate Cox model analysis showed that thymosin alpha 1 was the factor to improve the 28-day mortality ( HR = 0.15, 95% CI was 0.04-0.55, P = 0.004), old age ( HR = 1.10, 95% CI was 1.05-1.15, P < 0.001), accompanied by chronic renal dysfunction ( HR = 42.35, 95% CI was 2.77-648.64, P = 0.007), decrease of LYM at admission ( HR = 0.15, 95% CI was 0.04-0.60, P = 0.007) and the use of methylprednisolone ( HR = 4.59, 95% CI was 1.26-16.67, P = 0.021) were also risk factors for the increase of 28-day mortality. The use of immunoglobulin and antiviral drugs abidol and ganciclovir did not affect the 28-day mortality. After adjustment for age, gender, LYM and other factors, weighted multivariate Cox analysis model showed thymosin alpha 1 could significantly improve the 28-day survival of COVID-19 patients ( HR = 0.45, 95% CI was 0.25-0.84, P = 0.012). In terms of secondary outcomes, no statistical difference (all P > 0.05) was found between two groups in days without ventilator at 28 days after admission (days: 17.97±13.56 vs. 20.09±12.67) and the increase of LYM at 7 days after admission [×10 9/L: -0.07 (-0.23, 0.43) vs. 0.12 (-0.54, 0.41)]. But the decrease of CRP at 7 days after admission in thymosin alpha group was significantly greater than that in non-thymosin group [mg/L: 39.99 (8.44, 82.22) vs. 0.53 (-7.78, 22.93), P < 0.05]. Conclusion:Thymosin alpha 1 may improve 28-day mortality and inflammation state in COVID-19 patients.
ABSTRACT
The global coronavirus disease 2019 epidemic is still in a pandemic state. Aging population with underlying diseases is prone to become severe, and have a higher mortality. The treatment capacity of the critical care department directly determines the treatment success rate of critical illness. At present, there is still a certain gap between domestic and foreign countries in intensive care unit (ICU), which is not only in the allocation of medical staff, but also in the beds and settings. The current medical model cannot fully meet the needs of development. The experience and lessons of many major public health emergencies suggested that " dual track of peace and war" approach in discipline construction of critical care is the best medical model. Following the concept of "combination of peace and war", strengthening the discipline construction of critical care department in municipal and district designated hospitals, allocating reasonable standard ICU, step-down ICU and combat readiness ICU, establishing rapid response team, and strengthening regular training and scientific management may be the key measures to deal with the epidemic.
ABSTRACT
Objective:To investigate the differences in microbiological examination results between alcohol abuse and no alcohol abuse in adult ICU patients and the association between alcohol abuse and these differences.Methods:The adult patients with microbiological examination results were selected from the MIMIC-Ⅲ database and divided into two groups according to whether they had alcohol abuse. The two groups were matched by propensity score, and the similarities and differences in microbiological examination results were evaluated between the two groups after matching. The measurement data of non normal distribution were expressed by M ( Q1, Q3). Wilcoxon rank sum test was used for the comparison of the two groups, and the comparison of counting data was used χ 2 test or Fisher exact probability method. Results:After matching, the alcohol abuse patients were more likely to use mechanical ventilation (47.06% (1 379/2 930) vs. 52.66% (1 543/2 930), χ 2=18.14, P<0.001), had a higher positive rate in sputum samples (44.30% (400/903) vs. 49.41% (501/1 014), χ 2=4.81, P=0.028) and had a lower positive rate in other samples (26.85% (653/2 432) vs. 21.67% (541/2 496), χ 2=17.69, P<0.001). In blood samples, the percentage of Gram-negative bacteria was lower in the alcohol abuse group (26.87% (126/469) vs. 17.25% (74/429), χ 2=11.42, P<0.001), while the percentage of Gram-positive bacteria was higher (78.46% (368/469) vs. 86.01% (369/429), χ 2=8.17, P=0.004). The percentage of patients with Pseudomonas aeruginosa (3.75% (110/2 930) vs. 2.08% (61/2 930), χ 2=13.88, P<0.001) and Enterococcus sp. (8.19% (240/2 930) vs. 6.45% (189/2 930), χ 2=6.29, P=0.012) was lower in the alcohol abuse group. However, there was a higher percentage of patients with methicillin-resistant Staphylococcus aureus (2.32% (68/2 930) vs. 3.28% (96/2 930), χ 2=4.57, P=0.032) and Haemophilus influenzae (1.30% (38/2 930) vs. 2.01% (59/2930), χ 2=4.19, P=0.041) in the alcohol abuse group. For Staphylococcus aureus (61.10% (322/527) and 52.66% (267/507), χ 2=7.16, P=0.007) and Enterococcus sp. (75.83% (160/211) and 63.64% (56/88), χ 2=4.02, P=0.045), the alcohol abuse group had a lower resistance to levofloxacin; for Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae, the alcohol abuse group had a lower resistance to cephalosporins (all P<0.05). Conclusions:In adult ICU, alcohol abuse might increase the risks of using mechanical ventilation, and patients with alcohol abuse might be more prone to have respiratory tract infections. Alcohol abuse patients with blood infections were less likely to be infected with Gram-negative bacteria, but had a higher probability of Gram-positive bacteria infection. What is more, Alcohol abuse might increase the risks of infections with Haemophilus influenzae and methicillin-resistant Staphylococcus aureus. In alcohol abuse patients, the infection of Staphylococcus aureus, Enterococcus sp., Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae was less resistant to many antibiotics than that in no alcohol abuse patients.
ABSTRACT
Sepsis is caused by the imbalance of the host body's response to infection, which causes life-threatening organ dysfunction. Disorders of blood coagulation play a very important role in the development of sepsis. In sepsis, the body's coagulation system is activated, leading to hypercoagulability, while the anticoagulation mechanism is significantly inhibited, causing a large number of microthrombi to form, and disseminated intravascular coagulation (DIC) may occur. Although there are obvious controversies about the anticoagulation treatment of sepsis at home and abroad, we cannot deny the significance of anticoagulation treatment in sepsis. Only appropriate anticoagulation can effectively reduce the mortality in septic DIC, septic shock and high-risk population, and ultimately effectively reduce the occurrence of multiple organ dysfunction syndrome. The sepsis-induced coagulation dysfunction (SIC) score is currently used internationally to guide anticoagulation. SIC score is optimized based on the International Society on Thrombosis and Haemostasis (ISTH) overt DIC score and Sepsis-3, including platelet, international normalized ratio (INR) and sequential organ failure assessment (SOFA). The SIC score can sensitively monitor sepsis-induced coagulation dysfunction. When the SIC score is≥4, it is the best timing to initiate anticoagulation therapy. At present, the internationally recommended anticoagulant drugs include antithrombin (AT), thrombomodulin (TM), tissue factor pathway inhibitor (TFPI), heparin, etc., while the domestically recommended anticoagulant drugs are only unfractionated heparin and low molecular weight heparin. Before using anticoagulant drugs, it is necessary to evaluate the possibility of bleeding and thrombosis in the patients. At the same time, it is necessary to pay attention to the patient's primary disease. Try to adopt the treatment strategy of transitioning from unfractionated heparin to low molecular weight heparin without obvious anticoagulation contraindications.
ABSTRACT
Objective:To investigate the clinical effect of Jiedu Limai decoction in septic patients with syndrome of heat-toxin exuberance.Methods:A prospective randomized controlled trial was conducted. From March 2019 to April 2020, septic patients with syndrome of heat-toxin exuberance admitted to intensive care unit (ICU) of Shanghai General Hospital and Songjiang Branch of Shanghai General Hospital were enrolled as the research objects, and they were divided into routine treatment group and Jiedu Limai decoction group by the random number table method. Patients in both groups were given standard treatment in accordance with the guidelines, and patients in the Jiedu Limai decoction group were given Jiedu Limai decoction in addition to the standard treatment, once a day for 14 days. The 28-day survival of patients of the two groups were recorded, the acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, sequential organ failure assessment (SOFA) score, coagulation indexes, infection indexes, inflammatory cytokines and organ function indicators before treatment and 7 days after treatment in both groups were recorded, and the prognosis of the two groups were recorded.Results:A total of 259 patients with infection or clinical diagnosis of infection admitted during the experimental observation period were included, and those who did not meet the Sepsis-3 diagnostic criteria, more than 80 years old or less than 18 years old, with multiple tumor metastases, autoimmune system diseases, with length of ICU stay less than 24 hours, with acute active gastrointestinal bleeding and with incomplete data were excluded. One hundred patients were finally enrolled, with 50 patients in the routine treatment group and 50 patients in the Jiedu Limai decoction group. There were no statistically significant differences in coagulation indexes, infection indicators, inflammatory cytokines and organ function indicators before treatment between the two groups. After 7 days of treatment, the coagulation indexes, infection biomarkers and inflammatory cytokines in the Jiedu Limai decoction group were significantly lower than those in the routine treatment group [D-dimer (mg/L): 2.2 (1.8, 8.5) vs. 4.0 (1.5, 8.7), fibrinogen (Fib, g/L): 3.7 (3.4, 4.3) vs. 4.2 (3.7, 4.3), fibrinogen degradation product (FDP, mg/L): 7.2 (5.4, 10.2) vs. 13.2 (9.2, 15.2), procalcitonin (PCT, μg/L): 0.4 (0.2, 2.9) vs. 0.5 (0.2, 0.9), C-reactive protein (CRP, mg/L): 50.1 (9.5, 116.0) vs. 75.1 (23.5, 115.2), interleukin-6 (IL-6, ng/L): 31.6 (21.6, 81.0) vs. 44.1 (14.0, 71.3), all P < 0.05], and the levels of B-type brain natriuretic peptide (BNP) and kidney injury molecule-1 (KIM-1) were significantly lowered [BNP (ng/L): 261.1 (87.5, 360.3) vs. 347.3 (128.8, 439.4), KIM-1 (μg/L): 0.86 (0.01, 1.40) vs. 1.24 (1.05, 1.57), both P < 0.05]. Compared with the routine treatment group, the number of new organ failure in the Jiedu Limai decoction group was decreased (30.0% vs. 50.0%, P < 0.05). Although there was no significant difference in 28-day mortality between the two groups ( P > 0.05), the 28-day mortality in the Jiedu Limai decoction group was lower than that in the routine treatment group (18.0% vs. 24.0%).

Objective:To evaluate the hemostatic efficacy of N-carboxyethylchitosan fiber gauze (numbered NWL-K) in a leporine bleeding wounds of intraperitoneal parenchymal visceral.Methods:Sixty New Zealand rabbits were divided into two groups according to the randomized digital number method, with 30 rabbits per group. The leporine bleeding models of hepatic or splenic wound were made respectively. The two groups were subdivided into three groups: common gauze group, SURGICEL group and NWL-K group, with 10 rabbits per group. By analyzing the weight of excised liver tissue and amount of bleeding, the model stability was measured. The time to hemostasis and bleeding score in each group were analyzed every (20±5)seconds after compression for 30 seconds in the hepatic bleeding models or every (30±5)seconds after compression for 3 minutes in the splenic bleeding models. The adhesion between wound and gauze was evaluated at the same time.Results:There was no significant difference in the weight of excised liver tissue and amount of bleeding when the hepatic or splenic bleeding models were made ( P>0.05). It showed that the model was made stably and the hemostasis experiment would not be affected. In the splenic wound model experiment, the time to hemostasis was 255(233, 300)seconds in SURGICEL group and 210(180, 248)seconds in NWL-K group, both of which were significantly shorter than 465(383, 660)seconds in common guaze group ( P<0.05). NWL-K achieved shorter time to hemostasis than SURGICEL ( P<0.05). In the hepatic wound model experiment, the time to hemostasis was 90(85, 110)seconds in SURGICEL group and 70(70, 95)seconds in NWL-K group, both of which were significantly shorter than 250(225 290)seconds in common gauze group ( P<0.05). In the splenic wound model experiment, the bleeding score in NWL-K group and SURGICEL group decreased faster than that in common gauze group ( P<0.05). The difference of bleeding score was significant between NWL-K group and SURGICEL group at 180 seconds ( P<0.05). In the hepatic wound model experiment, the bleeding score in NWL-K group and SURGICEL group decreased faster than that in common gauze group at 50 seconds, 70 seconds and 90 seconds ( P<0.05). The bleeding score in common gauze group and NWL-K group showed significant difference at 30 seconds, 110 seconds and 130 seconds ( P<0.05). For the adhesion evaluation, both the water-absorbency and adhesion to tissue of NWL-K were better than common gauze and SURGICEL. Conclusions:For hepatic and splenic bleeding wounds, compared with other types of gauze, the application of NWL-K can effectively shorten the time to hemostasis and reduce the blood loss. The NWL-K shows high water-absorbency and firm adhesion to bleeding wound.
ABSTRACT
Objective:To explore the effect of KCa3.1 activating NLRP3 inflammasome in paraquat PQ treated-alveolar epithelial cells.Methods:The A549 cells were cultured in vitro and divided into the control group, TRAM-34 (specific inhibitor of KCa3.1) group, PQ group and PQ+TRAM-34 group. The expression of KCa3.1 was detected by immunofluorescence in A549 cells. Western blot was used to detect the level of the proteins related with the NLRP3 infammasome and NEK7 protein. And the level of cell potassium was detected by cell potassium concentration kit.Results:The level of KCa3.1 was significantly increased in A549 cells after PQ treatment by immunofluorescence. The expressions of NLRP3 infammasome-related proteins (NLRP3, ASC and Caspase-1) and NEK7 protein were increased after PQ treatment, and the expressions of NLRP3 infammasome-related proteins and NEK7 protein were decreased after inhibition of KCa3.1, and the difference was statistically significant [NLRP3/β-actin (control group vs TRAM-34 group vs PQ group vs PQ+TRAM-34 group): [ (0.02±0.00) vs (0.03±0.00) vs (0.74±0.00) vs (0.32±0.01) , ASC/β-actin (control group vs TRAM-34 group vs PQ group vs PQ+TRAM-34 group): [ (0.12±0.01) vs (0.11±0.03) vs (0.46±0.02) vs (0.17±0.03) ];Caspase-1/ β-actin (control group vs TRAM-34 group vs PQ group vs PQ+TRAM-34 group): [ (0.05±0.00) vs (0.04±0.00) vs (0.34±0.03) vs (0.15±0.01) ]; NEK7/ β-actin (control group vs PQ group vs PQ+TRAM-34 group);[ (0.38±0.03) vs (0.83±0.02) vs (0.51±0.01) , P<0.01]. The potassium level was decreased after PQ treatment and the degree could be declined by the KCa3.1 inhibitor by colorimetric detection with statistically significant difference (control group vs PQ group vs PQ+TRAM-34 group:[ (1.00±0.00) vs (0.60±0.05) vs (0.86±0.02) , P<0.01]. Conclusions:The KCa3.1 could promote the outflow of intracellular potassium and up-regulate the expression of NEK7, thereby activate the NLRP3 inflammatory in PQ-induced pulmonary fibrosis.
ABSTRACT
Objective:To investigate the molecule mechanism of nuclear translocation of hypoxia-inducible factor-1α (HIF-1α) in influenza A (H1N1) virus infected-alveolar epithelial cells.Methods:Human lung adenocarcinoma epithelial cells (A549 cells) were cultured in vitro, and cells in logarithmic growth phase were selected for experiments. ① Experiment 1: the A549 cell model with H1N1 virus infection was established by using H1N1 virus infected cells with multiplicity of infection (MOI) 1.0 for 24 hours (H1N1 virus infection group), and the blank control group was set up. Importin 4 and Importin 7 protein expressions were detected by Western Blot to investigate whether HIF-1α nuclear translocation depended on Importin 4 or Importin 7. ② Experiment 2: the A549 cells were infected with H1N1 virus under different MOI (0, 0.1, 0.5, 1.0, 2.0, 4.0) for 24 hours. Then the A549 cells were infected with H1N1 virus (MOI 1.0) for different time (0, 3, 6, 12, 18, 24, 36 hours). The septin 9 isoform 1 (SEPT9_i1) mRNA expression was detected by real-time fluorescence quantitative reverse transcription-polymerase chain reaction (RT-PCR) to investigate the effect of different MOI and infection time on the expression of SEPT9_i1. ③ Experiment 3: a cell model with SEPT9_i1 silencing was established by transfection of small interfering RNA (siRNA) for 24 hours (siRNA-SEPT9_i1 group), and the blank control group and blank vector control group (siControl group) were set up. Then the cells in the three groups were infected with H1N1 virus (MOI 1.0) for 24 hours after 24-hour transfection, and the SEPT9_i1 mRNA expression was detected by real-time fluorescence quantitative RT-PCR to investigate the interference efficiency of siRNA-SEPT9_i1. ④ Experiment 4: the cells were divided into siControl group and siRNA-SEPT9_i1 group. The transfection methods of two groups was as the same as experiment 3, and then the cells were infected with H1N1 virus (MOI 1.0) after 24-hour transfection. The distribution of HIF-1α was detected by immunofluorescence at 24 hours after infection. The M gene expression of virus was detected by real-time fluorescence quantitative RT-PCR at 6, 12, 24, 36, 48 hours after infection. The effects of SEPT9_i1 on HIF-1α translocation and virus replication were explored. ⑤ Experiment 5: the cells were divided into blank control group (complete medium), SP600125 group [100 μmol/L c-Jun N-terminal kinase (JNK) signaling pathway inhibitor SP600125 for 2 hours], H1N1 virus infection group (H1N1 virus of MOI 1.0 for 24 hours), H1N1 virus+SP600125 group (pretreated with 100 μmol/L SP600125 for 2 hours before 24-hour H1N1 virus infection). Real-time fluorescence quantitative RT-PCR was used to detect the expressions of SEPT_i1 mRNA and viral M gene to investigate the effect of JNK signaling pathway on SEPT9_i1 expression and virus replication. Results:① Experiment 1: compared with the blank control group, the protein expressions of Importin 4 and Importin 7 in the H1N1 virus infection group had no significant changes [Importin 4 protein (Importin 4/GAPDH): 1.08±0.03 vs. 1.05±0.03, Importin 7 protein (Importin 7/GAPDH): 0.87±0.11 vs. 0.78±0.03, both P > 0.05]. These indicated that the HIF-1α nuclear translocation in A549 cells might not be independent of Importin 4 and Importin 7 during H1N1 virus infection. ② Experiment 2: the SEPT9_i1 mRNA expression in A549 cells was increased with the increase in MOI and infection time of H1N1 virus, and peaked at MOI 2.0 or 18 hours after infection, and the differences were statistically significant as compared with MOI 0 or 0 hour after infection (2 -ΔΔCT: 1.39±0.05 vs. 1.00±0.00 at MOI 2.0, 1.47±0.04 vs. 1.00±0.00 at 18 hours, both P < 0.01). This indicated that the SEPT9_i1 expression in A549 cells was related to the MOI and the infection time during H1N1 virus infection. ③ Experiment 3: compared with the blank control group, the SEPT9_i1 mRNA expression in A549 cells was significantly decreased in the siRNA-SEPT9_i1 group (2 -ΔΔCT: 0.38±0.11 vs. 1.00±0.00, P < 0.01), and there was no significant difference between the siControl group and blank control group (2 -ΔΔCT: 1.03±0.16 vs. 1.00±0.00, P > 0.05). This indicated that SEPT9_i1 silence could inhibit the expression of SEPT9_i1 mRNA in H1N1 virus-infected A549 cells. ④ Experiment 4: HIF-1α nuclear translocation in the H1N1 virus-infected A549 cells in the siRNA-SEPT9_i1 group was significantly reduced as compared with the siControl group. The virus M gene expression after H1N1 virus infection in the siControl group was gradually increased, and peaked at 48 hours. The expression of virus M gene in A549 cells in the siRNA-SEPT9_i1 group was significantly down-regulated, and showed a statistically significant difference at 48 hours as compared with the siControl group (2 -ΔΔCT: 3.47±0.66 vs. 8.17±0.38, P < 0.05). This indicated that HIF-1α nuclear translocation and virus replication in H1N1 virus-infected A549 cells were inhibited after silencing SEPT9_i1. ⑤ Experiment 5: the expressions of SEPT9_i1 mRNA and virus M gene in A549 cells in the H1N1 virus infection group were significantly higher than those in the blank control group. However, the expressions of SEPT9_i1 mRNA and viral M gene in A549 cells in the H1N1 virus+SP600125 group were significantly lower than those in the H1N1 virus infection group (2 -ΔΔCT: SEPT9_i1 mRNA was 0.12±0.10 vs. 1.53±0.14, viral M gene was 2.13±0.10 vs. 4.66±0.14, both P < 0.05). There was no significant difference in above indicators between the SP600125 group and the blank control group. This indicated that the JNK signaling pathway could regulate the expression of SEPT9_i1 in A549 cells during H1N1 virus infection, and the JNK signaling pathway inhibition could down-regulate the expression of SEPT9_i1 and inhibit virus replication. Conclusion:The H1N1 virus regulates the expression of SEPT9_i1 by activating the JNK signaling pathway, thus increase HIF-1α transport efficiency and H1N1 replication.
ABSTRACT
Objective:To explore clinical predictive value of short-term dynamic changes in platelet counts (PLT) for prognosis of sepsis patients in intensive care unit (ICU).Methods:A retrospective cohort study was conducted. The patients aging 18 to 80 years old who were diagnosed by Sepsis-3 admitted to ICU of South Branch of Shanghai General Hospital from November 2015 to October 2018 were enrolled. According to whether the patients died within 28 days, they were divided into death and survival groups. General information and clinical baseline data [including disease severity score, infection biomarkers, PLT and organ function parameters (cardiac, liver, kidney, coagulation) and inflammatory cytokines] between the two groups were compared. Based on clinical indicators which had statistically significance, receiver operating characteristic (ROC) curve was drawn to predict the prognosis of the patients within 28 days. Then, risk factors of 28-day mortality of sepsis patients in ICU were screened by univariate and multivariate Logistic regression analysis. On the basis of multivariate Logistic regression analysis results, a multiparameter model was built, and the ROC curve was drawn to predict its prognosis within 28 days.Results:A total of 220 sepsis patients were enrolled. Among them, 61 patients died and 159 patients survived within 28 days with a 28-day mortality of 27.7%. Compared with the survival group, the patients in the death group were senior in age, more likely to suffer from chronic cardiovascular, chronic kidney and immune system disease, had higher scores in acute physiologic and chronic health evaluation Ⅱ (APACHEⅡ) score, sequential organ failure assessment (SOFA) score, disseminated intravascular coagulation (DIC) score and less PLT on the 1st and 7th day, sustained a higher incidence of persistent thrombocytopenia (PLT were all < 100×10 9/L in the first week after ICU admission) or acquired thrombocytopenia (PLT ≥ 100×10 9/L on the day of ICU admission, but dropped over 50% during the first week after ICU admission), were subjected to higher procalcitonin (PCT) and interleukin-6 (IL-6) levels and endured worse organ function (cardiac, kidney, coagulation) with statistically significant differences. However, there was no significant difference in gender, disease type, infection sites, pathogens or liver function. The ROC curve analysis for the 28-day prognosis of sepsis illustrated that the three disease severity scores could predict the 28-day prognosis of sepsis in ICU, and the area under ROC curve (AUC) of SOFA score was the highest (AUC = 0.878). The AUC of PLT on the 7th day was higher than that on the 1st day (AUC: 0.862 vs. 0.674), and the AUC of other clinical indicators were all < 0.8. Univariate and multivariate Logistic regression analysis showed that SOFA score [odds ratio ( OR) = 1.423, 95% confidence interval (95% CI) was 1.089-1.859, P = 0.010], troponin I (TnI; OR = 2.056, 95% CI was 1.057-3.999, P = 0.034), and persistent or acquired thrombocytopenia ( OR = 13.028, 95% CI was 4.033-42.090, P < 0.001) were three independent risk factors for 28-day mortality of the sepsis patients in ICU. Based on the multivariate Logistic regression analysis results, a multiparameter model was built with SOFA score, TnI and persistent or acquired thrombocytopenia, which showed a AUC of 0.926 to predict the 28-day mortality of sepsis patients in ICU. When the optimum cut-off value was 0.398 in the model, the sensitivity was 76.8%, and the specificity was 92.8%. Conclusions:Persistent or acquired thrombocytopenia within the first week of hospitalization proves to have a relatively momentous clinical predictive value for prognosis of sepsis patients in ICU. Clinical intervention focusing on thrombocytopenia may become a new potential therapy for these sepsis patients.

ABSTRACT
Objective To evaluate the prognostic value of ultrasonographic measurement of optic nerve sheath diameter (ONSD) and ONSD/eyeball transverse diameter (ETD) ratio in stroke patients during hospitalization. Methods Adult patients with stroke (ischemic stroke or hemorrhagic stroke) admitted to department of critical care medicine of Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine from November 2017 to November 2018 were enrolled. On the day of admission, ONSD and ETD (retina-retina at 3 mm behind the globe along) were detected by ultrasound, the ONSD/ETD ratio was calculated, and the baseline data and outcomes were recorded. Patients were divided into survival group and death group according to their survival status. Locally weighted scatterplot smoothing (LOWESS) and the receiver operating characteristic (ROC) curve were used to calculate the thresholds of ONSD and ONSD/ETD. The correlation between ONSD, ONSD/ETD and prognosis were assessed. Results Thirty-eight of 83 patients (45.8%) survived and were discharged from the hospital, while 45 patients died (54.2%). There were significant differences in Glasgow coma score (GCS), shifting of the middle structure, ONSD and ONSD/ETD between the death group and the survival group [GCS: 4.7±2.8 vs. 11.0±3.2, shifting of the middle structure (mm): 5.8±5.9 vs. 1.3±2.6, ONSD (mm): 5.5±0.4 vs. 4.4±0.5, ONSD/ETD: 0.25±0.02 vs. 0.20±0.02, all P < 0.05]. LOWESS and ROC curve analysis suggested thresholds of ONSD and ONSD/ETD for predicting adverse prognosis of stroke patients were 5.0 mm and 0.25, respectively. By adjusting the influence of confounding factors on prognosis, a prediction model based on ONSD was established, and the ROC curve was drawn. The area under the curve (AUC) was 0.978, the optimal predictive point of the model was 0.870, the sensitivity was 89%, and the specificity was 100%. The ONSD/ETD prediction model was also obtained, and the AUC was 0.988, the optimal prediction threshold of the model was 0.768, and the sensitivity for predicting adverse clinical prognosis was 94%, and the specificity was 97%. The stability of ONSD/ETD was better than that of ONSD. ONSD coefficient of variation was 0.14, and ONSD/ETD coefficient of variation was 0.13. Conclusions ONSD and ONSD/ETD were significantly correlated with the prognosis of critical patients with stroke. The mortality increased significantly in patients with an ONSD greater than 5.0 mm and ONSD/ETD greater than 0.25. ONSD and ONSD/ETD may be promising tools for early assessment of clinical outcomes in these patients.
