Effect of low-dose glucocorticoid on corticosteroid insufficient patients with acute exacerbation of chronic obstructive pulmonary disease

BACKGROUND: This study aimed to investigate the prevalence rate of critical illness-related corticosteroid insuffi ciency(CIRCI) and the effect of low-dose glucocorticoid on prognosis of CIRCI in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).METHODS: Since January 2010 to December 2012, 385 patients, who met the criteria of AECOPD, were enrolled in the Intensive Care Unit(ICU) of the First People's Hospital and Municipal Central Hospital of Xiangtan City. The AECOPD patients complicated with CIRCI screened by an adrenalcorticotrophic hormone test within 12 hours after admission to ICU were divided into a treatment group(n=32) and a control group(n=31) for a prospective, randomized and controlled clinical trial. Hydrocortisone(150 mg/d) or normal saline was injected intravenously for 7 days. The patients were followed up for 28 days after injection. The endpoint included 28-day survival time, non-shock time, ICU stay and the period of non-mechanical ventilation. The markers ofinfl ammation C-reactive protein, tumor necrosis factor-α, interleukin 6 and procalcitonin were measured at baseline and 7 days after treatment. The variables were analyzed by Student's t test, the non-parametric statistical test, the Chi-square test or the Kaplan-Meier method with SPSS18.0 statistic software. A P value 0.05 was considered statistically signifi cant.RESULTS: Totally 63 patients were diagnosed with CIRCI by an adrenalcorticotrophic hormone test and the prevalence rate was 16.4%. The shock rate of the AECOPD patients complicated with CIRCI was higher than that of the AECOPD patients without CIRCI(23.8% vs. 8.7%, P0.01). KaplanMeier analysis revealed that the 28-day survival time of the treatment group was obviously longer than that of the control group(P0.05). Compared with the control group, shock-free days within 28 days was longer in the treatment group(18.2±9.5 vs. 25.8±4.1, P0.05). Treatment with low-dose glucocorticoid obviously decreased the markers ofinfection and inflammation(P0.01), such as C-reactive protein(13.2±5.5 mg/L vs. 8.3±3.1 mg/L for the control group; 13.5±5.9 mg/L vs. 5.1±2.3 mg/L for the treatment group), tumor necrosis factor-α(26.1±16.2 g/L vs. 17.5±11.7 g/L for the control group; 25.0±14.8 g/L vs. 10.4±7.8 g/L for the treatment group) and procalcitonin(3.88 g/L vs. 2.03 g/L for the control group; 3.77 g/L vs. 1.26 g/L for the treatment group). Furthermore, the markers in the treatment group decreased more obviously than those in the control group(P0.01).CONCLUSION: The prevalence rate of CIRCI was higher in the patients with AECOPD in the department of critical medicine, and low-dose glucocorticoid treatment for one week reduced the 28-day mortality, shock time and markers ofinfection and infl ammation.

Abstract：

Objective To observe the effects and mechanism of pretreatment in rats with prostaglandin E1 on liver after hemorrhagic shock and resuscitation(HSR).Method In total,32 male SD rats were randomly(random number)divided into four groups(n=8):group A(sham group),group B(shock group),group C(HSR group)and group D(Lipo-PGEl+HSR).In group B,rats were sacrificed 90 min after shock,and in group C,rats were anesthetized and then subjected to hemorrhagic shock followed by resuscitation.In group D,rats were pretreated with Lipo-PGEI one hour before HSR.Liver function,NO and ET.1 were measured,and pathological changes of liver tissue in each group were observed,and the expres8ions of iNOS and ET.1 of liver tissue were measured by using immunohistochemistry 6 hours after HSR.Data were analyzed by analysis of variance,and P<0.05 was considered as significantly different in statitistics.Results The levels of liver iNOS and ET-I increased in HSR group compared with shock group [(O.225±0.080)vs.(0.082±0.021)and(0.292±0.047)vs.(0.082±0.035),P<0.05].Pretreatment with Lipo-PGEl markedly reduced the damage of Liver function,and lowered the levels of NO and ET-I.which were consistent with decrease in iNOS and ET-16 hours after HSR[(0.116±0.034)vs.(0.225±0.080)and(0.198±0.041)vs.(0.292±0.047),P<0.05].Conclusions Pretreatment with Lipo-PGEl could reduce liver injury after HSR.The mechanisms might be attributed to inhibiting iNOS and ET-1,regulating the balance of NO/ET-I.     

Study on the mechanism of resolvin D1 in alleviating brain injury after cardiopulmonary resuscitation through the inhibition of autophagy in pigs北大核心CSCD

Objective To investigate the mechanism of resolvin D1 (RvD1) in alleviating brain injury after cardiopulmonary resuscitation (CPR) through regulating autophagy pathway in pigs. Methods Nineteen male domestic pigs, weighing 30-41 kg, were divided into 3 groups using a random number table method: sham group (S group, n=5), CPR group (n=7), and RvD1 group (n=7). In the S group, the animals only experienced general preparation. In the CPR and RvD1 groups, the pig CPR model was established by 8 min of cardiac arrest caused by electrically induced ventricular fibrillation, and followed by 5 min of CPR. At 5 min after resuscitation, a dose of 0.6 μg/kg of resolvin D1 was injected via femoral vein in the RvD1 group, and the same amount of vehicle was similarly administered in the other two groups. At 1, 3, 6, and 24 h after resuscitation, blood samples were collected from the femoral vein to measure serum concentrations of neuron specific enolase (NSE) and S100β protein by ELISA. At 24 h after resuscitation, neurological function was evaluated by neurological deficit score (NDS), and then the animals were euthanized to obtain cerebral cortex for measuring the expressions of phosphorylated AMP-activated protein kinase (p-AMPK), phosphorylated mammalian target of rapamycin (p-mTOR), microtubule-associated protein light chain 3 (LC3 II) and p62 by Western blot. The variables were compared with One-way analysis of variance and then the Bonferroni test among the three groups. Results During 24 h after resuscitation, the NDS was significantly increased accompanied with significantly greater concentrations of NSE and S100β in serum in the CPR and RvD1 groups compared to the S group (all P<0.05). However, the NDS was significantly decreased at 24 h after resuscitation [(182±34) vs.(124±18), P<0.05], and serum NSE and S100β were significantly reduced starting 3 h after resuscitation in the RvD1 group compared to the CPR group [NSE (ng/mL): (23.1±3.8) vs. (18.0±2.2) at 3 h, (27.3±2.9) vs. (19.8±1.4) at 6 h, and (28.1±1.3) vs. (15.1±2.1) at 24 h; S100B (pg/mL): (1 611±208) vs. (1 322±100) at 3 h, (1 825±197) vs. (1 410±102) at 6 h, and (1 613±138) vs. (1 183±139) at 24 h, all P<0.05]. The expression levels of p-AMPK and LC3 II were significantly increased while the expression levels of p-mTOR and p62 were significantly decreased at 24 h after resuscitation in the CPR and RvD1 groups compared to the S group (all P<0.05). However, the expression levels of p-AMPK and LC3 II were significantly lower and the expression levels of p-mTOR and p62 were significantly higher at 24 h after resuscitation in the RvD1 group compared to the CPR group [p-AMPK: (0.28±0.08) vs. (0.17±0.03); LC3 II: (0.33±0.09) vs. (0.21±0.04); p-mTOR: (0.13±0.02) vs. (0.16±0.02); p62: (0.16±0.05) vs. (0.22±0.02), all P<0.05]. Conclusions The protective mechanism by which RvD1 alleviates brain injury after CPR in pigs might be related to the inhibition of neuronal autophagy mediated by AMPK/mTOR pathway. © 2022 Chinese Medical Association.

The effects of resolvin Dl on myocardial dysfunction after cardiopulmonary resuscitation in swine and its potential mechanisms北大核心CSCD

Objective To establish a porcine model of cardiopulmonary resuscitation to explore the effectiveness of resolvin Dl in improving post-resuscitation myocardial dysfunction and its potential mechanisms. Methods Twenty-eight male domestic pigs weighing 36 ± 3 kg were utilized. The pig model was established by 8 mins of untreated ventricular fibrillation and then 5 mins of cardiopulmonary resuscitation. The animals were randomly divided into 4 groups (n = 7 each): sham operation group (group S), cardiopulmonary resuscitation group (group CPR), low-dose resolvin Dl group (group LRD), and high-dose resolvin Dl group (group HRD). The animals in group S only got the general preparation without the procedure of cardiac arrest and resuscitation. At 5 rain after resuscitation, the doses of resolvin Dl 0. 3 gig/kg and 0. 6 kg/kg were respectively injected via the femoral vein of pigs in LRD and HRD groups, and meanwhile the equal volume of vehicle was given into the animals in the other two groups. At 3 h, 6 h and 24 h after resuscitation, the changes of stroke volume (SV) and global ejection fraction (GEF) were evaluated by a PiCCO monitor, and meanwhile the concentration of cardiac troponin I (cTNI) in serum was measured. At 24 h after resuscitation, the pigs were sacrificed, and myocardial tissue was obtained for the determination of tumor necrosis factor-alpha (TNF-a), interleukin-6 (IL-6), malondialdehyde (MDA), and superoxide dismutase (SOD) activity. Results Compared with group S, significantly decreased SV and GEF and markedly increased concentration of serum cTNI were observed in the other three groups with post-resuscitation myocardial dysfunction (all P <0. 05). Compared with group CPR, the values of SV and GEF were significantly increased while the concentration of serum cTNI was significantly decreased in LRD and HRD groups [SV (nil): 28±5, 31 ±5 vs. 23 ±4 at 3 hrs, 32±3, 36±6 vs. 27 ± 6at6hrs,35±5,4l±5vs.29±5at24hrs;GEF(%):l7±2,19i2vs.l4±lat3hrs,20±2,23 ±3 vs. 16±3 at6 hrs, 23±2, 26±3 vs. 20±2 at 24 hrs; cTNI (pg/nil):247±34, 230 ±26 vs. 324 ± 56 at3 hrs, 553 ±37, 501 ±34 vs. 611 ±44 at 6 hrs, 436 ±23, 371 ±29 vs. 553 ±47 at24 hrs, all P< 0. 05]. Compared with group LRD, myocardial function and serum markers were further significantly improved in group HRD (all P <0. 05). The inflammation and oxidative stress in myocardial tissue were observed in all the animals experiencing cardiac arrest and resuscitation, which were indicated by increased levels of TNF-a, IL-6 and MDA and decreased SOD activity. Compared with group CPR, the levels of TNF-a, IL-6 and MDA were significantly decreased while SOD activity was significantly increased in LRD and HRD groups [TNF-A (pg/mi): 442 ±87, 218 ±55 vs. 653 ± 112; IL-6 (pg/nil): 563 ± 68, 403±61 vs. 824±117; MDA (nmol/mg):3. 95±0. 96,2. 54±1. 2lvs. 6. 37±1. 26; SOD (U/mg): 2. 27±0. 93, 3. 36±0. 74 vs. 0. 89±0. 31, all P<0. 05). The morbidity of myocardial inflammation and oxidative stress were further significantly ameliorated in group HRD evidenced by the figure of biomarkers compared with group LRD (all P <0. 05). Conclusions Resolvin Dl can improve post-resuscitation myocardial dysfunction in a dose-dependent manner in swine, and the mechanism is related to the inhibition of inflammation and oxidative stress.

Objective To investigate pulmonary function in terms of tidal respiration and the influencing factors on it in <34 weeks premature infants with RDS at corrected gestational age of 40 weeks. Methods A total of 49 of <34 weeks premature infants with RDS (RDS group) and 36 of <34 weeks premature infants without RDS (non-RDS group) followed throughout entire twelve months were collected from December 2013 to October 2015. Of them, 35 RDS patients and 20 non-RDS patients had the pulmonary function examination. A total of 26 full term infants with hyperbilirubinemia (full term group) were recruited for comparison study. The differences in parameters of tidal respiration were compared among the three groups. The RDS patients were further divided into the mild RDS subgroup and severe RDS subgroup according to the severity of illness. Result (1) The TPEF [(0.17 ± 0.04) s vs. (0.23 ± 0.09) s], VPEF[(6.74 ±2.70) mL vs. (9.33 ±2.92) mL], TPEF/TE [(29.06 ±4.21)% vs. (38.27± 7.16)%], VPEF/VE [(32.54 ±4.43)% vs. (39.64 ±5.88)%] in RDS group were significantly lower than those in full term group (P < 0.05). The TPEF [(0.19 ± 0.06) s vs. (0.23 ± 0.09) s], TPEF/TE [(30.31 ±11.53)% vs. (38.27±7.16)%], VPEF/VE [(34.39 ±8.44)% vs. (39.64 ±5.88)%] in non-RDS group were significantly lower than those in full term group (P <0.05). The TPEF, TPEF/TE, VPEF/VE in RDS group were lower than those in non-RDS group, but the differences were not significant (P>0.05). (2) The TPEF, VPEF, TPEF/TE, VPEF/VE in mild RDS group were higher than those in severe RDS group, but the differences were not significant (P > 0.05). (3) Logistic regression analysis indicated that the gestational age was the protective factor of pulmonary function in premature infants with RDS. Conclusions Small airway resistance in <34 weeks premature infants with RDS is higher than that in full term infants. There was no significant difference in pulmonary function between RDS premature infants and non-RDS premature infants.

目的 观察连续性血液净化(CBP)对严重脓毒症患者的治疗作用,探讨CBP对严重脓毒症患者内皮细胞功能的影响.方法 按随机原则将严重脓毒症患者分为常规对照组22例,联合CBP组23例.两组患者均按照2008年脓毒症全球治疗指南常规治疗,联合CBP组同时行连续性静-静脉血液滤过(CVVH),置换液量为40 ml·kg-1·h-1,治疗72 h.分别于治疗前及治疗24 h、72 h(治疗终止10 min)行动脉血气分析,测定血浆活化蛋白C(APC)、可溶性细胞间黏附分子-1(sICAM-1)及血管性血友病因子(vWF)含量,并观察患者重症监护病房(ICU)住院时间、机械通气时间及28 d病死率.结果 联合CBP组患者ICU住院时间(d)及机械通气时间(d)均明显短于常规对照组(9.12±3.07比11.64±4.82;5.52±3.48比8.02±5.25,均P<0.05);28 d病死率明显低于常规对照组[13.0%(3/23)比40.9%(9/22),P<0.05].治疗72 h后,两组急性生理学与慢性健康状况评分系统Ⅱ(APACHEⅡ)评分(分)均明显下降,且联合CBP组下降程度优于常规对照组(3.96±4.07比1.68±2.43,P<0.05).常规对照组治疗前后APC、sICAM-1及vWF均无明显变化.联合CBP组APC在治疗72 h出现增高,sICAM-1在治疗24 h后、vWF在治疗72 h均较治疗前明显下降,且72 h时APC(μg/L)和vWF(mg/L)与常规对照组比较差异有统计学意义(15.12±7.57比10.01±5.83;1.58±0.73比2.64±1.34,P<0.05和P<0.01).所有死亡患者(12例)治疗前后APC、sICAM-1及vWF均无明显变化.存活组患者(33例)治疗72 h APC浓度(μg/L)较治疗前升高(13.55±7.11比10.37±7.60,P<0.01);sICAM-1(μg/L)及vWF(mg/L)均低于死亡组患者(61.03±45.58比104.64±71.08;1.88±1.21比2.70±0.95,均P<0.05).结论 CBP治疗能改善严重脓毒症患者受损的内皮细胞功能,减轻病情的严重程度,改善预后.

Abstract：

Objective To investigate the effect of continuous blood purification (CBP) in patients with severe sepsis, and to evaluate the change in endothelial cell function in patients with severe sepsis during CBP therapy. Methods According to random principle, 45 patients were divided into control group (n=22) and CBP group (n=23). All patients of both groups received routine treatment according to international guidelines 2008 for management of severe sepsis, but the patients in the CBP group also received continuous veno-venous hemofiltration (CVVH) for 72 hours, the ultrafiltrate volume was 40 ml·kg-1·h-1. Blood gas analysis was done before and 24 hours and 72 hours after CVVH therapy. The activated protein C (APC), soluble intercellular adhesion molecule-1 (sICAM-1) and von Willebrand factor (vWF) were measured. Also the length of stay in intensive care unit (ICU), time of mechanical ventilation, and death rate of patients in 28 days were observed. Results Compared with control group, the length of stay in ICU (days) and length of use of ventilator (days) in CBP group were shorter (9.12±3.07 vs. 11.64±4.82, 5.52±3.48 vs. 8.02±5.25, both P<0.05), and the death rate in 28 days was lower [13.0% (3/23) vs. 40.9% (9/22), P<0.05]. After therapy, patients in CBP group showed more reduction in the APACHEⅡ score compared with control group (3.96±4.07 vs. 1.68±2.43, P<0.05). Patients in control group showed less change in APC, sICAM-1 and vWF. APC in CBP group increased at 72 hours, and sICAM-1 and vWF of CBP group respectively decreased at 24 hours or 72 hours, while the APC (μg/L) and vWF (mg/L) at 72 hours showed significant change compared with that of the control group (15.12±7.57 vs. 10.01±5.83, 1.58±0.73 vs. 2.64±1.34, P<0.05 and P<0.01). In patients who died in 28 days (12 patients) there were little changes in APC, sICAM-1 and vWF, while patients who lived for 28 days (33 patients), showed significantly more reduction in sICAM-1 (μg/L) and vWF (mg/L, 61.03±45.58 vs. 104.64±71.08, 1.88±1.21 vs. 2.70±0.95, both P<0.05). The APC value (μg/L) was increased after treatment in patients who survived for 28 days (13.55±7.11 vs. 10.37±7.60, P<0.01). Conclusion CBP therapy can protect endothelial cell function and ameliorate dysfunction, and it reduces the severity of the severe sepsis as well as improves the outcome of patients with severe sepsis.
