Objective:To investigate the effects of continuous renal replacement therapy (CRRT) on plasma concentration, clinical efficacy and safety of colistin sulfate.Methods:Clinical data of patients received with colistin sulfate were retrospectively analyzed from our group's previous clinical registration study, which was a prospective, multicenter observation study on the efficacy and pharmacokinetic characteristics of colistin sulfate in patients with severe infection in intensive care unit (ICU). According to whether patients received blood purification treatment, they were divided into CRRT group and non-CRRT group. Baseline data (gender, age, whether complicated with diabetes, chronic nervous system disease, etc), general data (infection of pathogens and sites, steady-state trough concentration, steady-state peak concentration, clinical efficacy, 28-day all-cause mortality, etc) and adverse event (renal injury, nervous system, skin pigmentation, etc) were collected from the two groups.Results:A total of 90 patients were enrolled, including 22 patients in the CRRT group and 68 patients in the non-CRRT group. ① There was no significant difference in gender, age, basic diseases, liver function, infection of pathogens and sites, colistin sulfate dose between the two groups. Compared with the non-CRRT group, the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and sequential organ failure assessment (SOFA) were higher in the CRRT group [APACHE Ⅱ: 21.77±8.26 vs. 18.01±6.34, P < 0.05; SOFA: 8.5 (7.8, 11.0) vs. 6.0 (4.0, 9.0), P < 0.01], serum creatinine level was higher [μmol/L: 162.0 (119.5, 210.5) vs. 72.0 (52.0, 117.0), P < 0.01]. ② Plasma concentration: there was no significant difference in steady-state trough concentration between CRRT group and non-CRRT group (mg/L: 0.58±0.30 vs. 0.64±0.25, P = 0.328), nor was there significant difference in steady-state peak concentration (mg/L: 1.02±0.37 vs. 1.18±0.45, P = 0.133). ③ Clinical efficacy: there was no significant difference in clinical response rate between CRRT group and non-CRRT group [68.2% (15/22) vs. 80.9% (55/68), P = 0.213]. ④ Safety: acute kidney injury occurred in 2 patients (2.9%) in the non-CRRT group. No obvious neurological symptoms and skin pigmentation were found in the two groups. Conclusions:CRRT had little effect on the elimination of colistin sulfate. Routine blood concentration monitoring (TDM) is warranted in patients received with CRRT.

Objective:To construct an inter-hospital standardized transport scheme for patients supported by extracorporeal membrane oxygenation (ECMO) combined with modified early warning score (MEWS) and the transport checklist based on the theory of process reengineering.Methods:Through literature review, according to the actual situation of the Second Affiliated Hospital of Zhengzhou University, the MEWS scores and transport verification sheets were effectively combined to construct the inter-hospital standardized transport scheme for patients supported by extracorporeal membrane oxygenation. And according to the inter-hospital standardized transport scheme, the medical staff in the transport team were trained and assessed for ECMO patient transport knowledge. Using the convenient sampling method, a total of 223 ECMO patients admitted to the Second Affiliated Hospital of Zhengzhou University from January to December 2019 who were transported by conventional transport were selected as the control group. A total of 222 ECMO patients who were transported by the ECMO interhospital standardized transport scheme from January to December 2020 were selected as the observation group. This study Compared the incidence of adverse transport events in the two groups of and the transport knowledge of medical staff in the transport group before and after training.Results:The score of transport knowledge of ECMO patients of medical staff after training were higher than those before training, and the difference was statistically significant ( P<0.01) . The incidence of transport adverse events in the observation group was lower than that in the control group, and the difference was statistically significant ( P<0.05) . Conclusions:The standardized inter-hospital transport scheme for ECMO patients can form an efficient and safe standardized transport process, reduce the incidence of adverse transport events and improve the transport safety of ECMO patients.

Objective:To investigate the function of gasdermin D (GSDMD) in intestinal damage of mice with severe acute pancreatitis (SAP).Methods:The healthy C57BL/6 mice were divided into four groups randomly, including normal saline (NS) group, small interfering RNA (siRNA)-NS group, SAP model group and siRNA-SAP group, with 6 mice in each group. The SAP mouse model was reproduced by intraperitoneal injection of caerulein 50 μg/kg combined with lipopolysaccharide (LPS) 10 mg/kg; the NS group was given the same amount of NS; in the siRNA-SAP group and siRNA-NS group, siRNA 50 mg/kg was injected through the tail vein three times before modeling or injection of NS. The blood of mice eyeball in each group was taken 12 hours after modeling, and serum interleukins (IL-1β, IL-18) levels were detected by enzyme linked immunosorbent assay (ELISA). The mice were sacrificed to observe the general changes in abdominal cavity, the pancreas and ileum tissues were taken to observe the pathological changes under a light microscope. The expression of long-chain non-coding RNA uc.173 (lnc uc.173) was detected by reverse transcription-polymerase chain reaction (RT-PCR). Immunohistochemical method was used to detect the expression of tight junction proteins zonula occluden-1 (ZO-1) and Occludin in intestinal mucosal epithelial cells. Western blotting was used to detect the GSDMD protein expression level in the intestinal tissue.Results:The serum levels of IL-1β and IL-18 in the SAP model group were significantly higher than those in the NS group and the siRNA-NS group [IL-1β (ng/L): 146.66±1.40 vs. 44.48±5.76, 81.49±10.75, IL-18 (ng/L): 950.47±177.09 vs. 115.43±16.40, 84.84±21.90, all P < 0.05]; and the levels of IL-1β and IL-18 in the siRNA-SAP group were significantly lower than those in the SAP model group [IL-1β (ng/L): 116.26±15.54 vs. 146.66±1.40, IL-18 (ng/L): 689.96±126.08 vs. 950.47±177.09, both P < 0.05]. General observation showed that there were no obvious abnormalities in the abdominal cavity of the mice in the NS and siRNA-NS groups; the mice in the SAP model group and the siRNA-SAP group had different degrees of edema and congestion in the intestine; compared with the SAP model group, the abnormalities in the siRNA-SAP group was significantly reduced. Under light microscope, there were no obvious changes in the pancreas and intestinal mucosa in the NS group and the siRNA-NS group; the pancreatic tissue of the SAP model group and the siRNA-SAP group had different degrees of edema, inflammatory cell infiltration, and lobular structure damage, and the intestinal mucosa was damaged to a certain degree, and the villi were broken to varying degrees, but the damage in the siRNA-SAP group was lighter. The results of RT-PCR showed that the expression of lnc uc.173 in the intestinal tissues of the model SAP group was significantly lower than that of the NS group and the siRNA-NS group (2 -ΔΔCt: 0.26±0.12 vs. 1.01±0.37, 0.67±0.32, both P < 0.05), while the expression of lnc uc.173 in the siRNA-SAP group was significantly higher than that in the SAP model group (2 -ΔΔCt: 0.60±0.39 vs. 0.26±0.12, P < 0.05). Immunohistochemistry showed that ZO-1 and Occludin proteins in the NS group were distributed along the epithelial cells of the intestinal mucosa, showing a strong expression; ZO-1 and Occludin expressions were significantly reduced in the SAP model group and siRNA-SAP group, but the expressions in the siRNA-SAP group was higher than that in the SAP model group. Western blotting showed that the expression level of GSDMD protein in the intestinal tissues of the SAP model group was significantly higher than that of the NS group and the siRNA-NS group [GSDMD protein (GSDMD-N/β-actin): 1.99±0.46 vs. 1, 1.00±0.78, both P < 0.05]. Compared with the SAP model group, the expression of GSDMD protein in the siRNA-SAP group was significantly decreased [GSDMD protein (GSDMD-N/β-actin): 1.42±0.42 vs. 1.99±0.46, P < 0.05]. Conclusions:The systemic inflammatory response and intestinal mucosal barrier damage of SAP mice may be related to the increase of GSDMD expression in intestinal tissues. GSDMD mediates cell pyrolysis to promote the release of inflammatory factors, cause intestinal injury, and down-regulate the expression of intestinal epithelial cell tight junction proteins such as ZO-1 and Occludin, resulting in intestinal mucosal damage.

Objective:To investigate the effects of poly (ADP-ribose) polymerase-1(PARP-1) in intestinal mucosal barrier injury in rat model with severe acute pancreatitis (SAP).Methods:Twenty healthy male Wistar rats were divided into four groups ( n=5 each group) using a random table method: control, SAP, 3-aminobenzamide (3-AB), and 3-AB control groups. The SAP model was induced by intraperitoneal injection of cerulean with lipopolysaccharide. At 30 min, the rats were treated with the PARP-1 inhibitor, 3-AB, or normal saline,separately. After 12 h, all rats were sacrificed to harvest pancreas tissues, intestines tissues, and blood from the hearts for index detection. Serum amylase (AMY) and interleukin (IL)-6 levels were measured using an automatic biochemical instrument and enzyme-linked immunosorbent assay (ELISA), respectively.The protein expression of PARP-1 and nuclear factor (NF-κB) were measured using Western blot and that of occludin was measured using an immunohistochemical test. One-way analysis of variance was used for comparison of multiple groups of variables. Non-parametric tests of rank conversion were used when variances were not uniform. A P <0.05 was considered statistically significant. Results:Compared to the control group, the following indexes in the SAP group were significantly increased: ascites (with serious hemorrhage and necrosis in the pancreas and disordered intestinal villi),serum AMY and IL-6 levels, and the expression of PARP-1 and NF-κB. However, Occludin expression was significantly decreased. There was no significant difference between 3-AB group and 3-AB control group. Compared to the SAP group, the severity of SAP and pancreatitis-associated intestinal injury was significantly attenuated with the administration of 3-AB. Serum AMY and IL-6 levels were significantly decreased (serum AMY: 1 879.25 ± 736.6 U/L vs 5 569.33 ± 1993.48 U/L; IL-6: 77.98 ± 20.65 pg/mL vs 209.14 ± 79.08 pg/mL, both P<0.05), but the expression of PARP-1 and NF-κB were significantly increased (PARP-1: 1.44 ± 0.09 vs 1.49 ± 0.13; NF-κB: 0.63 ± 0.09 vs 0.96±0.08, both P<0.05). Similarly, Occludin expression was significantly decreased (6.7±1.5 vs 3.2±1.1, P<0.05). Conclusions:Inhibition of PARP-1 has protective effects on SAP associated intestinal mucosal barrier damage. The mechanism may be related to the inhibition of NF-κB signaling pathway and increase intestinal mucosal Occludin protein expression.

Objective:To analyze the risk factors of renal function recovery in patients with severe acute pancreatitis (SAP) combined with acute kidney injury (AKI).Methods:A retrospective study was conducted in 105 SAP patients with AKI who were admitted to ICU or EICU of the Affiliated Hospital of Qingdao University from January 2013 to October 2019. According to the recovery of renal function at 28 days, the patients were divided into the renal function recovery group and the poor recovery group. Multivariate logistic regression analysis was used to analyze the clinical data of the two groups and to determine the risk factors related to renal function recovery.Results:According to the recovery of renal function, 105 patients were divided into the renal function recovery group ( n=73) and the poor recovery group ( n=32). Compared with the renal function recovery group, patients in the poor recovery group were older, had a higher prevalence of diabetes and coronary heart disease and a higher score on the acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ); More patients had abdominal necrosis infection and abdominal hemorrhage. The proportion of patients who applied mechanical ventilation was higher in the poor recovery group. Multivariate logistic regression analysis showed that abdominal necrosis infection ( OR=5.088, 95% CI:1.041-24.871, P=0.044) and mechanical ventilation ( OR=4.615, 95% CI:1.126-18.904, P=0.034) were the independent risk factors of renal function recovery in SAP patients with AKI. Conclusions:Abdominal necrosis infection and mechanical ventilation are the independent risk factors for renal function recovery in patients with SAP and AKI.

Objective To compare the intestinal microbiota of septic shock patients and healthy subjects,and study the composition of the intestinal microbiota and its effect on septic shock patients in the intensive care unit (ICU).Methods A total of 15 stool samples were prospectively collected from septic shock patients admitted to the ICU in the First Affiliated Hospital of Zhengzhou University between June 2015 and February 2016,while 15 samples from healthy subjects served as controls.Bacterial DNA was submitted for 16S rDNA gene sequencing.The association between gut microbiota composition and clinical parameters was evaluated.Shannon index was used to assess the bacterial diversity.Results Compared with the healthy subjects,the composition of intestinal microbiota in septic shock patients changed significantly.The abundance of Proteobacteria and Fusobacteria were significantly higher in septic shock patients than in healthy subjects (23.71％ vs 3.53％,P=0.000 6;1.27％ vs 0.12％,P=0.059,respectively).In this study,29 species were identified,and the composition of intestinal microbiota in each patient was highly individualized.There was no significant difference in Shannon index between septic shock patients and healthy subjects (P=0.12).Conclusions The composition of intestinal microbiota in septic shock patients was characterized by high diversity and individualization,but there was the phenomenon of overproduction of single bacteria genus.The relationship between the composition of intestinal microbiota and clinical outcomes requires further exploration by large sample studies.

Objective To compare the efficacy and safety of induction therapy in 3+7 protocol and 3+10 protocol in children with acute myeloid leukemia (AML). Methods Two protocols were carried out in our hospital during January 2010 to January 2015, namely 3+7 protocol(AML-06,A group) and 3+10 protocol (modified AML protocol, B group). A total of 56 cases aged from 1 year-old to 13 year-old were enrolled in A group with male to female ratio at 31:25. Five of them were classified as FAB M1, 25 as M2, 11 as M4, 10 as M5, 2 as M6 and 3 as M7. Another 44 cases aged from 1 year to 12 years were enrolled in B group with a male to female ratio at 26:18, and 17 cases were classified as FAB M2, 14 as M4, 9 as M5, 2 as M6, and 2 as M7. Efficacy and adverse events were compared between the two groups. Results The complete remission rate (CR) of B group was 70.4%, while CR in A group was 48.2%. Considering the CR, 3+10 protocol showed higher efficacy than 3+7 protocol (P< 0.05). The major adverse event was bone marrow suppression. Treatment-related mortality (TRD) in A group was 1.8%, which was lower than that in B group (2.3%). The overall survival rate in A group was 75.0%, which was lower than that in B group (86.4%, P< 0.05). Conclusions The induction therapy of 3+10 protocol and 3+7 protocol showed effectiveness for AML treatment. The 3+10 protocol showed a higher CR than 3+7 protocol with no TRD increase, indicating that the 3+10 protocol should be recommended for AML treatment in children.
