Objective To investigate the effects of hydrogen on post - cardiac arrest brain injury in rabbits.Method Sixty New Zealand rabbits were randomly divided into two groups,namely experiment group ( group A,n =30 ) and control group ( group B,n =30 ).Inhalation of 2% hydrogen gas was conferred to rabbits immediately at the end of cardiac arrest modeling for 72 hours in the group A. Air instead was given to rabbits in the group B.Blood samples were collected before cardiac arrest (CA),and 4,12,24 and 72 hours after restoration of spontaneous circulation (ROSC) in all rabbits for determining the levels of hydrogen,tumor necrosis factor - α ( TNF - α),neuron - specific enolase (NSE) and protein S100β.At the same time,rectal temperature,mean arterial pressure,heart rate and respiration rate were recorded,and the neurologic deficit scoring (NDS) was carried out.The rate of systemic inflammatory response syndrome ( SIRS ) and the rate of survival of rabbits were analyzed. Results There was no significant difference in level of TNF - α activation between group A and group B within12 h of cardiopulmonary resuscitation (CPR).In group A,TNF - α level and the rate of SIRS peaked at 24 hours after CPR,which were higher than those in group B,and then decreased gradually,and the rate of survival was higher than that in group B in 72 hours after ROSC,the NSE was lower than that in group B at 24 hours after ROSC.In group B,S100β level began to increase significantly 4 hours after CPR,which was higher than that in group A,the level of NDS in group B was higher than that in group A 72 hours after ROSC.Conclusions Inhalation of hydrogen gas lessened inflammation and alleviated the brain injury after CPR.

Objective:To explore the effect of augmented renal clearance(ARC)on 24-hour area under the concentration-time curve to minimum inhibitory concentration ratio(AUC 24/MIC)of vancomycin and prognosis in critical children, thus to provide proposal for individual dosage regimen. Methods:Sixty-five critical children treated with vancomycin, who suffered from sepsis/septic shock, were brought into this retrospective cohort study.According to estimate glomerular filtration rate, these children were divided into ARC group ( n=27) and normal group ( n=38). The influencing factor of AUC 24/MIC of vancomycin and therapy prognosis for two groups were detected and analyzed. Results:There were no significant differences between two groups in basic setting (age, sex, weight), scores of pediatric sequential organ failure assessment and pediatric risk of mortality Ⅲ, infection markers (C-reactive protein and procalcitonin), glutamic-pyruvic transaminase, hypoproteinemia, usage of diuretic and vasoactive agent( P>0.05). The patients from ARC group showed lower levels than those from normal group in AUC 24/MIC of vancomycin[375.2(300.8, 489.4) vs. 443.6(412.3, 593.2), Z=2.263, P=0.024] and it′s target achievement ratio (TAR)(40.7% vs. 76.3%, χ2=8.440, P=0.005). When usage of diuretic and vasoactive agent, the AUC 24/MIC of ARC group was lower than that of normal group( P<0.05). But there was no significant difference between ARC group and normal group regarding hypoproteinemia( P>0.05). The days of body temperature steady at least 48 hours[7.0(5.5, 9.0)d vs. 6.0(5.0, 8.0)d], the length of hospital stay[39.0(21.0, 58.0)d vs. 20.5(16.0, 28.0)d], the length of PICU stay[14.0(9.0, 31.5)d vs. 10.0(5.0, 15.0)d] were longer than those in normal group( P<0.05). There were no significant differences between ARC group and normal group regarding days of ventilation and infectious markers decreased at least 50%, as well as 28-days mortality( P>0.05). The multivariable analysis showed that the presence of ARC, hypoproteinemia, use of diuretics and vasoactive agent were significantly associated with AUC 24/MIC of vancomycin( P<0.05). Conclusion:ARC may down regulate levels of AUC 24/MIC and TAR of vancomycin.During ARC period, the usage of diuretic and vasoactive agent could affect the AUC 24/MIC of vancomycin.Individual dosage regimen should be employed for critical children suffered with ARC.

Objective:To investigate the prognostic value of proprotein convertase subtilisin/kexin type 9 (PCSK9) and blood lipid indexes in patients with sepsis.Methods:Patients with sepsis or septic shock who were ≥ 18 years old and met the Sepsis-3.0 diagnostic criteria admitted to the department of critical care medicine of Binzhou Medical University Hospital from January to October 2021 were enrolled. Healthy adults at the same period were selected as healthy control group. Baseline characteristics, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and sequential organ failure assessment (SOFA) score were recorded. Venous blood samples were collected within 24 hours after diagnosis, and serum PCSK9 was determined by enzyme-linked immunosorbent assay (ELISA) at 1, 3 days and 5 days. Meanwhile, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), total cholesterol (TC), triglyceride (TG) and lipoprotein A were detected. The differences of each index between sepsis group (28-day death group and survival group) and healthy control group were compared. Meanwhile, the indexes of patients with different severity and 28-day prognosis in sepsis group were compared. Receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of PCSK9 and blood lipid for the prognosis of sepsis. Multivariate Logistic regression was used to analyze the influencing factors for the prognosis of sepsis, and the Kaplan-Meier survival curve at 28th day was drawn.Results:There were 50 patients in sepsis group (including 19 patients with sepsis, 31 patients with septic shock) and 27 patients in healthy control group. In the sepsis group, 19 patients died and 31 patients survived within 28 days. The serum PCSK9 in the sepsis group was significantly higher than that in the healthy control group [μg/L: 223.09 (198.47, 250.82) vs. 188.00 (165.27, 214.90), P < 0.01], and HDL-C, LDL-C, TC and lipoprotein A were significantly lower than those in the healthy control group [HDL-C (mmol/L): 0.82±0.35 vs. 1.45±0.24, LDL-C (mmol/L): 1.53 (1.14, 2.47) vs. 2.89 (2.55, 3.19), TC (mmol/L): 2.03 (1.39, 2.84) vs. 4.24 (3.90, 4.71), lipoprotein A (g/L): 8.80 (5.66, 17.56) vs. 27.03 (14.79, 27.03), all P < 0.01]. PCSK9 in the sepsis death group was higher than that in the survival group [μg/L: 249.58 (214.90, 315.77) vs. 207.01 (181.50, 244.95), P < 0.01], and the HDL-C, LDL-C and TC were lower than those in the survival group [HDL-C (mmol/L): 0.64±0.35 vs. 0.93±0.30, LDL-C (mmol/L): 1.32±0.64 vs. 2.08±0.94, TC (mmol/L): 1.39 (1.01, 2.23) vs. 2.69 (1.72, 3.81), all P < 0.01]. With the progression of the disease, the PCSK9 in the sepsis death group and the survival group was significantly lower than that within 1 day of diagnosis (all P < 0.05). ROC curve analysis showed that PCSK9 had higher predictive value of 28-day death than HDL-C, LDL-C, TC [area under ROC curve (AUC) and 95% confidence interval (95% CI): 0.748 (0.611-0.885) vs. 0.710 (0.552-0.868), 0.721 (0.575-0.867), 0.702 (0.550-0.854)]. Multivariate Logistic regression analysis showed that PCSK9 was an independent risk factor affecting the 28-day prognosis of sepsis (β value was 1.014, P = 0.020). Kaplan-Meier survival curve analysis showed that when PCSK9 ≥ 208.97 μg/L, with the increase of PCSK9, the 28-day survival rate of sepsis patients decreased significantly. Conclusions:PCSK9, HDL-C, LDL-C and TC can all predict the 28-day prognosis of patients with sepsis. The prognostic value of PCSK9 is the highest. PCSK9 is an independent risk factor affecting the prognosis of sepsis. In the early stage of the disease, PCSK9 may have a good predictive value for the prognosis of sepsis. When PCSK9 ≥ 208.97 μg/L, the 28-day survival rate decreased significantly.
