Objective To investigate the effect of exogenous hydrogen sulfide (H2S) on intestinal mucosal barrier after cardiopulmonary resuscitation (CPR) in cardiac arrest (CA) rabbits. Methods Forty-four male New Zealand rabbits were divided into sham operation group (Sham group, n = 12), post-cardiac arrest syndrome (PCAS) group (n = 16) and H2S intervention group (PCAS+NaHS, n = 16) according to random number table method. The rabbit model of PCAS was established by tracheal clamping and suffocation, and CPR was started at 5 minutes after CA. However, Sham group did not clamp the tracheal intubation after anesthesia, and the other operations were the same as those in PCAS group. In the PCAS+NaHS group, a bolus of NaHS (0.5 mg/kg), a H2S donor, was injected via era vein 1 minute before the start of CPR, followed by a continuous injection of NaHS (1.5 mg·kg-1·h-1) for 3 hours, while the rabbits in other group were intravenously injected with the same volume of normal saline (NaCl 0.9%). Intestinal and portal vein blood samples were collected 24 hours after return of spontaneous circulation (ROSC). The level of serum fluorescein isothiocyanate-dextran (FD-4) was detected by fluorescein isothiocyanate (FITC) labeling method to reflect intestinal mucosal permeability. After hematoxylin-eosin (HE) staining of small intestine tissues, the morphological changes of mucosa were observed under light microscope, and the intestinal mucosa injury score was calculated. The expression of tight junction protein ZO-1 in intestinal mucosa was detected by immunohistochemistry. The content of malondialdehyde (MDA) in small intestinal tissue was determined by thiobarbituric acid chromogenic method, the activity of superoxide dismutase (SOD) was determined by xanthine oxidation method, and the level of myeloperoxidase (MPO) was determined by double antibody sandwich enzyme linked immunosorbent assay (ELISA) to reflect the oxidative stress and inflammatory reaction in small intestinal tissue. The expression of apoptosis protein (caspase-3) and autophagy related protein (Beclin-1, LC3) in small intestine tissue was detected by Western Blot. Results 12, 13 and 14 animals were successfully resuscitated in Sham group, PCAS group and PCAS+NaHS group respectively, while 12 animals in each group survived to the end of experiment. Compared with Sham group, the level of FD-4 in portal vein serum was significantly increased in PCAS group (mg/L: 11.95±0.59 vs. 1.43±0.48, P < 0.05), the pathological injury and inflammation infiltration were obviously aggravated under light microscope, the score of small intestine injury was significantly increased (4.21±0.37 vs. 0.36±0.18, P < 0.05), the expression of tight junction protein ZO-1 in the intestine was visibly down-regulated detected by immunohistochemistry, MDA content and MPO activity were significantly increased [MDA (nmol/mg): 3.65±0.32 vs. 1.54±0.24, MPO (U/g): 362±35 vs. 134±18, both P < 0.05], while SOD activity was significantly decreased (U/mg:78.84±7.49 vs. 115.48±8.48, P < 0.05), the expression levels of cleaved capase-3, Beclin-1 and LC3 proteins in the intestine were significantly increased (caspase-3/β-actin: 1.11±0.08 vs. 0.21±0.02, Beclin-1/β-actin: 2.08±0.11 vs. 0.42±0.03, LC3/β-actin: 1.05±0.07 vs. 0.37±0.05, LC3-Ⅱ/ LC3-Ⅰ: 1.28±0.14 vs. 0.17±0.02, all P < 0.05). Compared with PCAS group, the portal vein serum FD-4 level in PCAS+NAHS group was significantly decreased (mg/L:5.59±0.48 vs. 11.95±0.59, P < 0.05), the intestinal mucosal pathological injury and inflammatory cell infiltration were significantly decreased, the score of small intestine injury was significantly decreased (2.18±0.47 vs. 4.21±0.37, P <0.05), the expression of ZO-1 in intestine was significantly increased, MDA content and MPO activity in intestine were significantly decreased [MDA (nmol/mg): 2.65±0.31 vs. 3.65±0.32, MPO (U/g): 251±21 vs. 362±35, both P < 0.05], while SOD activity was significantly increased (U/mg: 96.86±7.52 vs. 78.84±7.49, P < 0.05), while the expression of activated caspase-3, Beclin-1 and LC3 proteins was significantly decreased (caspase-3/β-actin: 0.72±0.06 vs. 1.11±0.08, Beclin-1/β-actin: 0.96±0.08 vs. 2.08±0.11, LC3/β-actin: 0.72±0.06 vs. 1.05±0.07, LC3-Ⅱ/ LC3-Ⅰ:0.83±0.09 vs. 1.28±0.14, all P < 0.05). Conclusion H2S has a protective effect on intestinal mucosal injury induced by CA/CPR, which may be related to tight junction protein ZO-1 up-regulation, oxidative stress alleviation, inflammation reduction, apoptosis and autophagy inhibition.

Objective To observe and assess the effects of full marathon on hemodynamics and cardiac electrophysiology of marathon amateurs without adverse event after the race.Methods Fiftyone subjects were included in the final analysis of the study,blood pressure,heart rate,body surface electrocardiogram (ECG) of all subjects under static status before the race and within (15-30) min after the race were detected,and sufficient amounts of the peripheral blood and the radial arterial blood specimens of all subjects under static status before the race and within (15-30) min after the race were collected instantly.The peripheral blood was used for measuring markers of muscle injury and NT-proBNP,and the radial arterial blood was taken for blood gas analysis.The QTc interval,QRS,PR interval,and QTd interval were recorded from the 12-lead ECG report.Results Compared with those under static status before the race,the systolic blood pressure,diastolic blood pressure,mean arterial blood pressure and heart rate of all the subjects within (15-30) min after the race were significantly higher (P＜0.05).When the markers of striated muscle injury were compared before and after the competition,levels of CK,cTNI,LDH,and myoglobin after the race were significantly increased compared with them under static status before the race (P ＜0.05),and the level of NT-proBNP after the race was also significantly increased compared with it before the race (P＜0.05).When blood gas analysis before the race was compared with that after the race,the PH values after race were significantly lower than it before race (P＜0.05).The level of lactic acid after the race was significantly higher than it before race (P＜0.05).After the race,the levels of PCO2,SBE and HCO3-decreased significantly compared with those before race (P＜0.05),and the QTc and QTd intervals after the race increased significantly compared with those before the race,however,the QTc interval and QTd interval for all subjects before and after the competition were within the normal range.Conclusions Full marathon significantly affect the myocardial electrophysiological markers of healthy amateur athletes without chronic diseases,but those markers fluctuate within the normal range.

Objective To investigate the effects of hydrogen (H2) on myocardium injury post-cardiac arrest (CA) in rabbits.Methods Sixty New Zealand rabbits were randomly divided into H2 treatment group (n = 30) and control group (n = 30) by random number table. The rabbit CA model was established by means of electrical stimulation of external membrane, both groups were mechanically ventilated. Cardiopulmonary resuscitation (CPR) was performed after 6 minutes of nonintervention, and stopped after restoration of spontaneous circulation (ROSC). Inhalation of 2％ H2 gas was conferred to rabbits immediately at the end of CA modeling for 72 hours in H2 treatment group. Air was given to rabbits in control group instead. The survival rate of rabbits was analyzed. Heart rate, ventricular premature beat frequency, and the levels of blood samples cardiac troponin I (cTnI), left ventricular ejection fraction (LVEF), B-type natriuretic peptide (BNP), and blood lactic acid (Lac) were collected before CA and after ROSC in all rabbits. Rabbits were sacrificed and microstructure injury was observed by electric microscope after ROSC 72 hours.Results There were 28 animals ROSC in both groups; the survival number in H2 treatment group was higher than that in control group at 72 hours after ROSC (number: 15 vs. 7,χ2 = 4.791,P = 0.029). In the early stage of ROSC, the heart rate of two groups slowed down, the number of premature ventricular increased, and then gradually recovered; the heart rate in H2 treatment group was returning to normal more quickly than that in control group at 48 hours after ROSC (bpm: 319±63 vs. 362±40,P < 0.05); the ventricular premature beat frequency was lower than that in control group at 72 hours after ROSC (times per minutes: 9.1±4.3 vs. 15.0±8.0,P < 0.05). The animals of two groups had different degrees of myocardial damage and cardiac insufficiency after ROSC, and restored with the extension of time. Compared with control group, the level of BNP in H2 treatment group was significant decreased at 24 hours after ROSC (ng/L: 385±98 vs. 488±174,P < 0.05), the levels of cTnI and Lac were significant decreased at 48 hours after ROSC [cTnI (μg/L:1.83±0.68 vs. 2.83±0.98, Lac (mmol/L): 5.5±1.6 vs. 7.9±2.6, bothP < 0.01], the LVEF was slightly higher than that at 72 hours after ROSC (0.690±0.040 vs. 0.650±0.041,P = 0.051). Compared with control group, less damage to myocardial ultra structure was found in H2 treatment group at 72 hours after ROSC.Conclusion Inhalation of H2 alleviates cardiac dysfunction and myocardial injury after CPR.

Objective:To analyze and summarize the causes of unscheduled suspension of knee and hip arthroplasty and to provide the method for optimizing the patient's pre-operative management and improving the efficiency of medical resources as well as the patient's satisfaction.Methods: The data for this report was retrospectively collected from September 2013 to August 2014 in our hospital,from cases of knee and hip arthroplasty that were suspended before the scheduled operation time.Acquisition data from the collected cases including the patients' gender,age and the surgical procedure.At the same time,the suspension reasons were recorded and analyzed.All the decisions of suspension was made by the surgeons and the anesthesiologists according to the abnormal result of preoperative examinations,after communicating with the patients and their families and obtaining their understandings.Results: In the collecting period,our department scheduled 1 146 cases of knee and hip arthroplasty,among which 1 003 were completed,143 suspended (12.5％ suspension rate).Among the causes of suspension,the top four common causes were cardiovascular disease (44/143,31％),other infections (20/143,14％),bacteriuria (18/143,13％) and inappropriate surgical indication (16/143,11％).Other causes include surgeon's reason,Blood system abnormalities,high inflammatory index,deep vein thrombosis,other diseases uncontrolled,abnormal liver function and poor diabetes mellitus control,etc.For the rate of suspension,there was no significant difference between the patients with different genders (male: 15.0％,and female: 11.7％,P=0.149),or age (≤50 years: 13.0％;51-65 years: 11.6％;66-80 years 13.3％;>80 years 11.1％;P=0.864).However compared with knee arthroplasty,hip arthroplasty had a higher suspension rate (knee arthroplasry 11.1％,hip arthroplasry 16.1％,P=0.021).Conclusion: It is important to educate and manage the patients before their knee and hip arthroplasty.Through clear diagnosis,detailed medical history analysis careful physical examination,and targeted outpatient examinations and tests for which priority was focused on cardiovascular or other system diseases we could minimize the occurrence of operative suspension post hospitalization,therefore improving the efficiency of the use of medical resources.

Objective:To compare the pain control efficiency of continuous adductor canal block (ACB) and femoral nerve block (FNB) in total knee arthroplasty.Methods:From April to September 2016,patients with severe knee osteoarthritis undergoing primary unilateral total knee arthroplasty (TKA) were prospectively observed,and all the patients were randomized received ultrasound-guided continuous ACB or FNB after surgery.Numeric pain rating scales (NPRS)pain scores in rest and activity 2,6,12,24 and 48 h after surgery were collected,and the preoperative and postoperative quadriceps strength at 24 and 48 h were analyzed.Opioids consumption and anesthesia related adverse effects were also recorded.Results:In the study,40 patients were enrolled,with 20 patients in each group,male ∶female =7 ∶ 33,the age:(63.8 ± 10.1) years,and the body mass index (BMI):(28.5 ± 3.5) kg/ m2.The general conditions were comparable between the two groups.Though the rest pain 2 h after surgery [ACB =0.0(0,6),FNB =3.0(0,5),P=0.004] and activity pain 12 h post operation [ACB =3.0(3,0),FNB =5.5(0,10),P =0.004] were lower in ACB group compared with FNB group,there was no statistical difference in the other pain checking points between the two groups.The quadriceps strength 24 h and 48 h after surgery were (85.3-± 27.6) N and (80.0 ± 30.1) N in ACB group,(69.0 ± 29.4) N and (64.4 ± 32.0) N in FNB group,both of them were declined by time.The exact data were higher in ACB group,however,there was no statistical difference between the two group by repeated measurements variance analysis(F =2.703,P =0.108).Four patients in ACB group and five in FNB acquired additional use of dolantin once (100 mg/per time) within 24 h.And among them,three patients acquired once dolantin in ACB,two in FNB,from 24 to 48 h postoperation.There were five patients who suffered nausea postoperation in ACB group,and one who reported xerostomia.Four patients in FNB had nausea with vomiting,and three experienced xerostomia.Deep vein thrombosis appeared in 2 patients in FNB group,but no one in ACB group.Conclusion:Continuous ACB is not superior in pain control after TKA compared with FNB,and the quadriceps strength could be reserved more by this method,which performed early benefits in fast rehabilitation.

Objective To observe the impact of improving the compliance of ventilator bundle on morbidity of ventilator-associated pneumonia (VAP) in intensive care unit (ICU) patients undergoing mechanical ventilation (MV) guided by context of Joint Commission International (JCI) settings, and to study the oral care efficacy of suction tube sponge brush. Methods A prospective study was conducted. The patients who needed MV admitted to Department of Critical Care Medicine of the First Affiliated Hospital of Xiamen University from January 2013 to December 2016 were enrolled. In the context of JCI settings, necessary measurements were taken to enhance the compliance of ventilator bundle each year. In 2013, the preventive measures were set up and the education was strengthened. In 2014,the compliance of hand hygiene and bedside elevation was strengthened. In 2015, a control study was conducted to evaluate the effect between the traditional cotton dipped in chlorhexidine and the suction tube sponge brush rinsed with chlorhexidine on oral health impact parameters. The suction tube sponge brush rinsed with chlorhexidine oral care was introduced to improve compliance. In 2016, electronic bundle checklist for daily self-audits was conducted. The annually morbidity of VAP through the software of hospital and ICU was collected and calculated. The annual incidence of VAP was indicated by the VAP cases per 1000 MV days. Based on the VAP incidence rate in 2013 as 1, the VAP incidence-rate ratio (IRR) of each year was calculated. Results During the study period, a total of 2733 patients admitted to the ICU, including 1403 patients undergoing MV. Ninety-four of the 1403 patients with community-acquired pneumonia (CAP), aspiration pneumonia, back elevation ban, incomplete information, and withdrew from the study were excluded. 1399 patients undergoing MV were enrolled in the final analysis, with total MV days of 11012 days, and 94 patients occurred VAP. The annual incidence of VAP was progressively declined from 2013 to 2016, and the VAP cases per 1000 MV days were 17.0, 10.0, 5.9, 3.5 cases, respectively. Based on the VAP incidence rate in 2013, the IRR of VAP from 2014 to 2016 was also progressively declined, which was 0.59 [95% confidence interval (95%CI) = 0.35-0.98], 0.35 (95%CI = 0.18-0.64), and 0.21 (95%CI = 0.09-0.41), with statistical significance (all P < 0.05). In 2013, ICU patients had the lowest rates of bedside elevation and hand hygiene compliance, which were 28.57% and 54.29%, respectively. Compared with 2013, by the implementation of two quality control circle (QCC) projects for bedside elevation and hand hygiene, the rates of bedside elevation and hand hygiene compliance were improved significantly in 2014, which were 82.35%, 91.18%, respectively (both P < 0.05). In 2015, the compliance of chlorhexidine oral care which was the worst performed in 2014 had been improved by the method of QCC, and the rate of the compliance was significantly higher than that in 2013 (87.10% vs. 62.86%, P < 0.05). Compared with 2013, bundle compliance was significantly increased in 2016, except for the sterile operation of the suction tube [daily wake and weaning: 95.00% vs. 71.43%, bedside elevation for over 30°: 92.50% vs. 28.57%, hand hygiene: 97.50% vs. 54.29%, chlorhexidine mouth care once per 6-8 hours:95.00% vs. 62.86%, turned back and posture drainage: 97.50% vs. 80.00%], the differences were statistically significant (all P < 0.05). The incidences of bad breath, dirt residue and plaque were significantly lower in the group of oral care by using suction tube sponge brush with chlorhexidine (30 cases) compared with the group of traditional cotton pad with chlorhexidine (30 cases; bad breath: 10.0% vs. 40.0% %, dirt residue: 16.7% vs. 70.0%, plaque: 3.3% vs. 30.0%, all P < 0.05). There was no significant difference in the incidence of oral ulcers between the oral brush group and the traditional group (10.0% vs. 30.0%, P > 0.05). Conclusion Ventilator bundle can effectively reduce the morbidity of VAP in the context of JCI settings, and the oral care by using suction tube sponge brush and chlorhexidine can effectively improve oral hygiene.
