ABSTRACT

Objective To investigate the effect of salidroside on intestinal mucosal immune status in rats under compound stress of hypoxia and training (HTCS) and the mechanism. Methods SD rats were randomly divided into HTCS model group (model), placebo group (placebo) and salidroside group (salidro). Model group received no intervention, and placebo and salidro group received intraperitoneal injection of normal saline and salidroside, respectively. Then, ileum tissue of rats were collected and the intestinal damage was assayed by HE staining and Chiu scores. Intestinal permeability indices, including serum D-diamine oxidase (DAO), D-lactic acid (DLA) and endotoxin (END) and secretory immunoglobulin A (sIgA) of intestinal tissue were detected by ELISA. T lymphocyte subsets of intestinal tissue were detected by flow cytometry. Expression of tight junction molecules, including ZO-1, Claudin-3, occluding, were detected by PCR and western blot. Activation of TLR4/NF-κB signaling pathway was detected by Western blot analysis. Results Compared with model group and placebo group, salidro group had the decreased intestinal mucosal injury and low Chiu score, and the level of intestinal permeability indices including serum DAO, DLA and END fell off. CD4+ T cell percentage, CD4+/CD8+ ratio and sIgA level were went up, while CD8+ T cell percentage was went down. mRNA and the level of protein expressions of ZO-1, claudin-3 and occludin increased, while activation of TLR4/NF-κB signaling pathway was inhibited. Conclusion Salidroside can alleviate the intestinal barrier injury and improve intestinal mucosal immune status of rats under compound stress of hypoxia and training via inhibiting TLR4/NF-κB signalling pathway.

ABSTRACT

Objective:To explore the clinical effect of high-titer plasma in the treatment of severe viral pneumonia in children.Methods:A total of 80 eligible children with severe viral pneumonia in intensive care unit of Guangzhou Women and Children Medical Center were enrolled in this retrospective study from January 2016 to June 2019, According to whether high-titer plasma was used or not, patients were divided into the high-titer plasma group (40 cases) and non-high-titer plasma group (40 cases). Chi-square test, Fisher's exact probability test and Mann-Whitney U test were used to compare the basic data, infection indicators, blood gas and ventilator parameters related indicators, treatment and prognosis of the two groups. Results:There were no significant differences in age, sex, admission weight, onset days and fever days between the high-titer plasma group and non-high- titer plasma group before entering the study (all P>0.05); There were no significant differences in the worst SOFA score, Murray lung injury score, chest X-ray involvement and sepsis within 3 days (all P>0.05). There were no significant differences in white blood cells, neutrophils and c-reactive protein between the two groups before and after entering the study (day 3 and 7) (all P> 0.05). There were no significant differences in arterial partial pressure of oxygen (PaO 2), partial pressure of carbon dioxide (PaCO 2), lactic acid (Lac), mean airway pressure (MAP), oxygenation index (P/F) and oxygen index (OI) between the two groups before and after entering the study (day 1, 3 and 7) (all P>0.05). There were no significant differences in the use of immunoglobulin, hormone, fiberoptic bronchoscope, blood purification, high frequency ventilator, pulmonary surfactant and extracorporeal membrane between the two groups (all P>0.05). There were no statistical differences in the number of days using invasive ventilator, the number of days staying in PICU and the total length of hospital stay between the two groups (all P>0.05). There was shorter time of the body temperature decreased to normal time in the high-titer plasma group than in the non-high-titer plasma group ( Z=-2.10, P=0.04). The survival rate of the high-titer plasma group was higher than that of the non-high-titer plasma group (85% vs 65%, χ2=4.27, P=0.04). The average daily cost of the high-titer plasma group was less than that of the non-high-titer plasma group, 3 688.38 yuan (2 335.49, 5 741.51) yuan vs 3 979.24 yuan (2 670.68, 9 992.62) yuan, but the difference was not statistically significant (Z=-1.35, P=0.18). No serious adverse reactions were observed during the treatment with high-titer plasma. Conclusions:The treatment of severe viral pneumonia with high-titer plasma can shorten fever time and improve survival rate. High-titer plasma can be used as a safe and effective treatment for severe viral pneumonia.

ABSTRACT

Objective To investigate the role of nuclear transcription factor kappa B (NF-κB) -matrix metalloproteinase-9 (MMP-9) signaling pathway in delayed encephalopathy after acute carbon monoxide poisoning (DEACMP). Methods 150 male SD rats were randomly assigned to air control group (AC group) , CO poisoning group (CO group) , pyrrolidine thiocarbamate (PDTC) + CO poisoning group (PC group). DEACMP model was reconstructed by modified intraperitoneal injections. The 1, 3, 7, 14, and 21 d after intraperitoneal injection were observed here by different approaches. Morris water maze test was used to test the learning and memory ability of rats.HE staining was used to observe the morphology of hippocampal CA3 cells. Immunofluorescence and Western Blot methods were used to detect the expression of NF-κB and MMP-9. RT-PCR was used to measure the expression of MMP-9 mRN A. Transmission electron microscopy was used to observe the ultrastructure of synapses. Results After14 days, the average intubation period of CO group was longer than that of AC group (P < 0.05) , and that of PC group was shorter than that of CO group (P < 0.05). However, average intubation period of PC group was longer than that of AC group (P< 0.05). In CO group, the expression of NF-κB in hippocampus increased (day 1). At day 3, the expression of NF-κB rapidly increased. The expression of MMP-9 gene and protein increased in the first three days and then decreased thereafter. The expression of NF-κB and MMP-9 in PC group was lower than that in CO group (P < 0.05) , while it was higher than AC group (P < 0.05). The peak value of apoptosis in CO group was delayed to 7-14 d after exposure, the apoptotic cells in PC group decreased significantly, and it was obvious on the 14 th day.Electron microscopy showed that the damage of synapses ultrastructure in CO group was significantly heavier than that in PC group on the 14 th day. Conclusions NF-κB-MMP-9 signal pathway leads to DEACMP, and PDTC could alleviate the impairment of learning and memory ability in rats with acute CO poisoning.

ABSTRACT

Objective@#To investigate the effects of astaxanthin on neuronal injury in hippocampus of rats after acute carbon monoxide poisoning(ACMP) and the relationship with NF-κB inflammatory signaling pathway.@*Methods@#Male SD rats screened by water maze were randomly divided into three group(n=50): control group (NC group), CO poisoning group (COP group), CO poisoning+ astaxanthin group (AST group) . ACMP rat model was established by static inhaled exposure method. Meanwhile, rats in AST group were further given astaxanthin twice a day by gavage.At 1 day, 7 days, 14 days, 21 days and 28 days after CO poisoning (10 rats in each group were selected), the learning and memory abilities were evaluated by Morris water maze test. The pathological changes of the neurons in hippocampal CA1 region were observed by hematoxylin-eosin(HE) staining.The expression and activation of NF-κB in hippocampus were detected by immunoblotting and immunofluorescence, and the expression of TNF-α and IL-6 protein in hippocampus were examined by ELISA.@*Results@#Morris water maze test showed that there were no significant difference in escape latency and crossing platform times between the three groups (P>0.05). Compared with NC group, the escape latency of COP group was prolonged at 14, 21 and 28 days after CO poisoning (t=-6.04, -6.28, -8.18, all P<0.05), and the number of crossing platform was decreased (t= 5.96, 7.85, 6.51, all P<0.05). Compared with the COP group, the escape latency of the rats in AST group at the 14, 21 and 28 days was shortened (t=4.74, 4.82, 5.98, all P<0.05), and the number of crossing platform was increased (t=-3.72, -4.45, -6.53, all P<0.05). Compared with NC group, the number of NF-κ B positive cells in CA1 area of hippocampus in COP group increased at every time point (t=-8.62, -18.00, -16.67, -11.15, -6.22, all P<0.05); the number of NF-κ B positive cells in CA1 area in AST group decreased at 7 d, 14 d, 21 d and 28 d after CO poisoning, the difference was statistically significant (t= 6.55, 6.96, 4.40, 4.17; all P<0.05). Western blot showed that the changes of NF-κB protein was similar to that of immunofluorescence. After 7 days of CO poisoning, the level of NF-κB protein in hippocampus of COP group was (1.44±0.08), it was higher than that of NC group (t=-20.07, P<0.05), while that of AST group was (0.68±0.10), it was lower than that of COP group (t=10.23, P<0.05). The results of Elisa showed that TNF-α and IL-6 in the hippocampus of COP group were higher than those of NC group at every time point(all P<0.05), while compared with COP group, TNF-α and IL-6 in AST group were lower (all P<0.05). After 7 days of CO poisoning, TNF -α in COP group ((39.04±5.29) pg/ml)was higher than that in NC group ((14.13±2.12) pg/ml) (t=-7.58, P<0.05); TNF -α in AST group ((25.77±3.31) pg/ml) was lower than that in COP group (t=3.69, P<0.05). After 7 days of CO poisoning, the level of IL-6 in COP group ((181.79±9.12) pg/ml)was higher than that in NC group ((73.12±11.04) pg/ml) (t=-8.24, P<0.05), and the level of IL-6 in AST group ((121.47±9.80) pg/ml) was lower than that in COP group (t=7.80, P<0.05).@*Conclusion@#The excessive inflammatory response which mediated by NF-κB signaling pathway is involved in ACMP-induced neuronal damage in hippocampus.Astaxanthin can down-regulate the expression of NF-κB inflammatory signaling pathway related proteins, and pave a way for the treatment of ACMP brain damage and cognitive dysfunction.

ABSTRACT

Objective To determine the levels of blood pancreatic stone protein/ regenerating protein(PSP/reg)and to explore the value of PSP/ reg in assessing severity and predicting prognosis of sepsis with or without panc-reatic damage. Methods In this prospective study,the clinical data and blood samples to measure PSP/ reg levels in 1,3 and 7 days after admission in the Pediatric Intensive Care Unit,Hunan Children's Hospital,from the children with sepsis from September 2013 to September 2014 were collected. According to levels of pancreatic trypsin(amylase or li-pase),the children were divided into normal group,mildly elevated group(1 - 3 times),and severely elevated group (more than 3 times);based on the condition of sepsis,the children were divided into sepsis group and severe sepsis group. Chi - square test,nonparametric rank sum test,Spearman correlation and area under the receiver operating cha-racteristic curve(AUC),Kaplan - Meier survival curves were used for statistical analysis. Results (1)A total of 226 children with sepsis were included in this study,among them pancreatic trypsin was normal in 159 cases(70. 4% ), pancreatic trypsin mildly elevated in 44 cases( 19. 4% ),and pancreatic trypsin severely elevated in 23 cases (10. 2% );125 cases(55. 3% )were sepsis,and 101 cases(44. 7% ,of which 29 cases were sepsis shock)were severe sepsis.(2)The correlation between PSP/ reg and serum amylase was maximum,while PSP/ reg had some correlation with serum lipase,but there was no correlation with C - peptide,insulin,glucose.(3)When pancreatic trypsin was normal or mildly elevated,severe sepsis group had higher levels of PSP/ reg than that of sepsis group(Z = - 7. 627,- 2. 965,P =0. 000,0. 003);while pancreatic trypsin was severe elevated,there was no significant difference in PSP/ reg levels be-tween sepsis group and severe sepsis group(Z = - 0. 134,P = 0. 894).(4)The AUC of PSP/ reg and procalcitonin to assess severity of sepsis were greater than 0. 7 in the children whose pancreatic trypsin was normal or mildly elevated, and there was no significant difference between them(P ﹥ 0. 05);while the AUC of C - reactive protein and WBC were less than 0. 7.(5)PSP/ reg levels gradually increased in non - survival children in 3 and 7 days,while survival children gradually declined. The AUC of PSP/ reg to predict prognosis was 0. 775,and 60 μg/ L was viewed as the critical point, sensitivity 89% ,specificity 67% . Children with PSP/ reg levels ≤60 μg/ L had higher rate of survival than children with ﹥ 60 μg/ L(χ2 = 36. 874,P = 0. 000). Conclusions PSP/ reg is closely associated with pancreatic exocrine func-tion,but PSP/ reg still can assess severity and predict prognosis in children with sepsis and pancreatic damage.

ABSTRACT

ObjectiveTo explore the value of elevated amylase in assessment of severity of the disease and its inlfuencing factors in critically ill children.MethodThe clinical data from critically ill children hospitalized in pediatric intensive care unit were retrospectively analyzed from November 2009 to June 2014. According to levels of serum amylase, the critically ill children were divided into normal serum amylase group (≤103 IU/L) and elevated serum amylase group (>103 IU/L). The differences between two groups were compared.ResultsA total of 1920 critically ill children were enrolled, most of whom had primary respiratory and neurological diseases. Among them, 1470 children had normal serum amylase (76.6%) and 450 children had ele-vated serum amylase (23.4%). The elevated serum amylase group had signiifcantly higher rate of organs failure (≥4), lower rate of PCIS (<70), higher rate of invasive mechanical ventilation and mortality than those in normal serum amylase group (P<0.001). The correlation of serum amylase with lipase blood, urine amylase, blood urea nitrogen and creatinine were signiifcant (r=0.246 to 0.683,P<0.001). Blood amylase was positively correlated with shock index (r=0.111,P=0.002) and negatively correlated with respiratory failure index (r=0.133,P<0.001).ConclusionsSerum amylase could be used to assess the severity of disease. The elevated amylase was closely related to pancreatic exocrine function, renal function, ischemia, and hypoxia. The elevated serum amylase in critically ill children is a warning sign.
