ABSTRACT
Objective:To investigate the predictive value of sputum heparin binding protein(HBP) in sepsis related acute respiratory distress syndrome(ARDS).Methods:This study was a prospective case-control study.A total of 134 children with sepsis who were admitted in PICU at Hunan Children′s Hospital from January 2020 to November 2021 were included, including 63 children who had completed fiberoptic bronchoscopy.The 63 children were divided into sepsis without ARDS group, sepsis with mild ARDS group, and sepsis with moderate to severe ARDS group according to the presence and severity of ARDS.Sputum was collected and HBP was detected in all children with sepsis when they were admitted to the hospital.The alveolar lavage fluid within 72 hours of admission was reserved for HBP.The levels of interleukin (IL)-6 and tumor necrosis factor (TNF)- α were detected, and the blood biochemistry, pulmonary imaging, pediatric critical case score and other data within 72 hours were collected.Results:(1) Among 63 children with fiberoptic bronchoscopy, 29 were in sepsis without ARDS group, 18 were in the sepsis with mild ARDS group, and 16 were in the sepsis with moderate to severe ARDS group.There was no significant difference in the pediatric critical case score and the location of primary infection focus among the three groups at admission.The primary infection focus was respiratory system in 36 cases, whose sputum HBP level was (42.1±9.8) ng/mL, and 27 children with other systems infection, whose sputum HBP level was (37.8±10.8) ng/mL, there was no significant difference between two groups ( t=1.65, P=0.104). (2) There were significant differences in sputum HBP, alveolar lavage fluid HBP, IL-6 and TNF-α levels among sepsis with mild ARDS group, sepsis with moderate and severe ARDS group and sepsis without ARDS group ( P<0.05). The sputum HBP of 34 children with sepsis combined with ARDS was positively correlated with alveolar lavage fluid HBP, IL-6, TNF-α levels and lung injury score, and negatively correlated with SpO 2/FiO 2 ( P<0.05). (3)Among the 34 children with sepsis combined with ARDS, the sputum HBP concentration of children with invasive ventilation was significantly higher than that of children with non-invasive ventilation ( P<0.05). The sputum HBP concentration in children with three or more organ damage was significantly higher than that of children with two or less organ damage ( P<0.05). The sputum HBP concentration of dead children was higher than that of surviving children ( P<0.05). (4) The area under curve of sputum HBP for predicting ARDS was 0.772 (95% CI: 0.655~0.889). When the cut-off point value of sputum HBP was 27.9 mU/L, whose sensitivity and specificity were 70.6% and 79.3%, respectively.The area under curve of sputum HBP for predicting moderate and severe ARDS was 0.793 (95% CI: 0.661~0.926). When the cut-off point value of sputum HBP was 51.55 mU/L, whose sensitivity and specificity were 81.3% and 76.6%, respectively. Conclusion:Sputum HBP is elevated in children with sepsis and ARDS, which is related with the severity of the disease.Sputum HBP has a good predictive value for the diagnosis and severity of children with sepsis and ARDS, and can be used as a clinically effective and convenient evaluation index for children with sepsis related ARDS.
ABSTRACT
Objective:To explore the clinical value of serum insulin combined with cardiac-related markers in evaluating the severity of sepsis associated encephalopathy (SAE).Methods:The clinical data of 130 children with sepsis who admitted to the Pediatric Intensive Care Unit of Hunan Children's Hospital from January 2018 to December 2021 were analyzed retrospectively, and the differences of serum insulin and cardiac-related markers in children with sepsis and SAE were compared.Results:The levels of serum insulin, creatine kinase isoenzyme, hypersensitive troponin T, and N-terminal cerebral urine peptide in the SAE group were significantly higher than those in the non-SAE group ( P<0.05), but there was no significant difference in heart rate and lactic acid ( P>0.05). The levels of serum insulin, creatine kinase isoenzyme, hypersensitive troponin T, N-terminal cerebral urine peptide and lactic acid in the death group were significantly higher than those in the survival group ( P<0.05), while the heart rate was not significantly different ( P>0.05). The area under ROC curve of serum insulin, creatine kinase isoenzyme, hypersensitive troponin T, and N-terminal cerebral urine peptide in predicting SAE were 0.841, 0.599, 0.700, and 0.667, respectively; in terms of judging the prognosis of sepsis, the area under ROC curve were 0.647, 0.669, 0.645, and 0.683, respectively; and in terms of judging the prognosis of children with SAE, the areas under the ROC curve were 0.509, 0.682, 0.666 and 0.555, respectively. Binary logistic regression equation was established with serum insulin, creatine kinase isoenzyme, hypersensitive troponin T, and N-terminal cerebral urine peptide: Y=8.153×NT-proBNP+1.704×CTnT-hs+27.121×insulin+0.946×CK-MB+1.573. The area under the ROC curve of the new variable Y in predicting sepsis SAE, evaluating the prognosis of sepsis, and predicting the prognosis of children with sepsis and SAE was 0.890, 0.756, and 0.729, respectively. Conclusions:Serum insulin, creatine kinase isoenzyme, hypersensitive troponin T, and N-terminal cerebral urine peptide can be used alone to determine the severity of sepsis and sepsis in children with SAE. The combined value of the four indicators is obviously better than that of the single indicator. The combined application of the four indicators may better evaluate the severity of sepsis and SAE.
ABSTRACT
Objective:To study the clinical features of children with pertussis and the risk factors of severe pertussis.Methods:A retrospective analysis was performed based on clinical data and laboratory examination results of hospitalized children with pertussis who admitted to the intensive care unit, respiratory department, and emergency general department at Hunan Children′s Hospital from January 2019 to March 2020.According to the age, the patients were divided into age ≤3 months group( n=58)and age >3 months group( n=64). According to sputum culture, 63 cases were divided into negative sputum culture group and 59 cases were positive sputum culture group.The patients were also divided into vaccinated group( n=19)and unvaccinated group( n=103). Severe disease was seen in 28 cases, and the other 94 cases had the modest disease.The clinical characteristics between two groups were compared, and the risk factors of severe pertussis pneumonia were analyzed. Results:The hospitalization days in age ≤3 months group was higher than that in age >3 months group.It was also found that shortness of breath, apnea, cyanosis after coughing, heart rate decline were more common in age ≤3 months group than those in age >3 months group( P<0.05). The incidences of respiratory failure and heart failure in positive sputum culture group were higher than those in negative sputum culture group.Clinical characteristics such as hospitalization days, hospitalization expenses, peak white blood cell count, peak lymphocyte count, and incidence of bacterial infection were higher in severe pertussis group than those in non-severe pertussis group( P<0.05). Four patients were treated with exchange blood transfusion, and one patient died.Logistic regression analysis revealed that fever, wheezing, cyanosis after coughing and white blood cell count>20×10 9/L were risk factors for severe pertussis.White blood cell count of 20×10 9/L and lymphocyte count of 14×10 9/L had the highest sensitivity and specificity in predicting severe pertussis(0.71, 0.78; 0.54, 0.79). Conclusion:The younger the children are, the more likely they have shortness of breath, apnea, cyanosis, heart rate falls, and the longer the hospital stay.Bacterial infection will aggravate pertussis.Patients with fever, wheezing, cyanosis after coughing, and white blood cell count>20×10 9/L are more likely to develop severe pertussis.The white blood cell count >20×10 9/L and the lymphocyte count >14×10 9/L are associated with severe pertussis.
ABSTRACT
Objective:To investigate the clinical characteristics and therapeutic strategies of huge esophageal stones.Methods:One patient with esophageal esophageal calculus admitted to Beijing Friendship Hospital, Capital Medical University, who failed in undergoing endoscope treatment and shifted to an operation were retrospectively analyzed, and analyzed and summarized in combination with relevant literature.Results:The patient has significant dysphagia and severe malnutrition requiring further medical intervention. CT examination found that the lower esophagus was incarcerated with huge stones, and gastroscopy showed stones were obstructing the lumen, esophageal polyps and muscle bridges under the stones.Because the stones were large and hard, multiple endoscopic stone removal failed, and then the stones were successfully removed by thoracic surgery. The patient recovered well after surgery and had no complications such as anastomotic leakage or stenosis.Conclusions:Esophageal stones are easy to cause obstruction, and even lead to perforation, so it should be actively managed clinically. For patients with esophageal stones who have failed multiple endoscopic stone removals, thoracotomy can be used as a further treatment.
ABSTRACT
Objective:To investigate the clinical value of serum cystatin C(Cys C) and neutrophil gelatinase associated lipocalin(NGAL) combined with cardiac biomarkers in the evaluation of sepsis with renal injury in children.Methods:The clinical data of 130 children with sepsis(67 cases in sepsis non AKI group and 63 cases in septic AKI group)admitted to pediatric intensive care unit(PICU) at Hunan Children′s Hospital from May 2018 to December 2019 were retrospectively analyzed.The differences of serum Cys C, NGAL and cardiac related biomarkers between sepsis and septic kidney injury were analyzed and compared.Results:The levels of serum Cys C, NGAL and amino-terminal pro-brain natriuretic peptide(NT-proBNP) in children with septic AKI were significantly higher than those in children of sepsis non AKI group(all P<0.01). There were no significant differences in creatine kinase isoenzyme(CK-MB)and high-sensitivity troponin T(cTnT-hs) between two groups (all P>0.05). The levels of CK-MB, cTnT-hs, NT-proBNP, Cys C and NGAL in the dead children were significantly higher than those in the surviving children ( P<0.05). In terms of predicting of AKI, the area under the ROC curve of NGAL, Cys C and NT proBNP were 0.724, 0.759 and 0.747, respectively.Regarding predicting the survival and death of sepsis, the area under the ROC curve of NGAL, Cys C and NT proBNP were 0.719, 0.722 and 0.769, respectively.In predicting the prognosis of children with sepsis and kidney injury, the area under the ROC curve of NGAL, Cys C and NT proBNP were 0.683, 0.651 and 0.682, respectively.The binary Logistic regression equation was established by Cys C, NGAL and NT-proBNP, Y=0.970 NGAL+ 0.9441 BNP+ 1.815 Cys C-2.944.In predicting kidney injury, evaluating prognosis of sepsis and predicting prognosis of sepsis with kidney injury, the area under ROC curve of new variable Y were 0.882, 0.802 and 0.808, respectively. Conclusion:NGAL, Cys C and NT-proBNP can be used to judge sepsis and sepsis with kidney injury alone.The evaluation value of combined detection of three indexes is better than that of single index.Therefore, the combined use of the three indicators may be better to judge the condition of children with sepsis and kidney injury.
ABSTRACT
Objective:To investigate the effect of the timing of continuous renal replacement therapy (CRRT) administration on the prognosis of acute kidney injury (AKI) in children.Methods:The medical records of children with AKI who were admitted to the Intensive Care Unit of Hunan Children′s Hospital from March 2015 to February 2020 and underwent CRRT were prospectively analyzed.The children who met the criteria were divided into early group (defined as AKI 1 and 2) and delayed group (defined as AKI 3) according to AKI stage.The general conditions, indicators when CRRT was initiated, and prognosis of the children in two groups were recorded.Results:(1) A total of 39 children were included in the study, including 23 in the early group and 16 in the delayed group.There were no significant differences in age, gender, body weight and proportion of mechanical ventilation between two groups ( P>0.05). The score of critical cases in the early group was higher than that in the delayed group ( P=0.008). (2) There were no significant differences in serum potassium and bicarbonate when CRRT was initiated between two groups ( P>0.05). The urine output in the early group was higher than that in the delayed group ( P>0.001). The serum creatinine and urea nitrogen in the early group were lower than those in the delayed group ( P>0.05). (3) The 28-day survival rate and proportion of renal function recovery at 28 days in the early group were significantly higher than those in the delayed group ( P>0.05). The duration of CRRT, ICU stay and duration of mechanical ventilation in the early group were shorter than those in the delayed group ( P>0.05). Conclusion:Early initiation of CRRT at AKI stage 1 and 2 can improve the 28-day survival rate and renal function recovery of survivors when critically ill children are complicated with AKI.
ABSTRACT
Objective:To discuss the role of continuous blood purification (CBP) therapy in children with severe adenovirus pneumonia.Methods:A total of 114 children with severe adenovirus pneumonia admitted to the Department of PICU at Children′s Hospital of Hunan Province from June 2018 to July 2019 were selected as the research objects.According to whether treated with CBP, they were divided into CBP group and control group.The following indicators during the process of treatment were compared between two groups, including respiratory mechanics indicators[respiratory index(PaO 2/FiO 2), dynamic lung compliance(Cdyn)]; hemodynamic indicators(heart rate and mean arterial pressure); changes in levels of inflammatory factors interleukin(IL)-6, IL-10, tumor necrosis factor(TNF)-α and the prognosis 28 days after admission. Results:The respiratory mechanics index, serum IL-6 and TNF-α levels of two groups after treatment were significantly lower than those before treatment, and the serum IL-10 level was significantly higher than that of this group before treatment.There were statistical differences in the CBP group before and after treatment, while there was no statistical difference in control group.In the CBP group, the serum IL-6 and TNF-α levels after treatment were significantly lower than those of the control group( P<0.05), and the serum IL-10 level was significantly higher than that of the control group( P<0.05). The 28-day mortality rate of patients in CBP group was 8.6%(3/35), which was significantly lower than 13.9%(11/79) of control group ( P<0.05). Conclusion:CBP could improve the main respiratory mechanical indexes of adenovirus pneumonia and decrease the level of inflammatory cytokines.
ABSTRACT
Objective:To summary the mixed infection as well as clinical characteristics and analyze the risk factors for mixed infection of severe adenovirus pneumonia(SAP) in children.Methods:The clinical data of 114 children with SAP were retrospectively analyzed.Multivariate Logistic regression analysis was performed to assess the risk factors for mixed infection.Results:The incidence age was from 6 months to 2 years(62.5%). High fever(94.7%), cough(98.2%), dyspnea(86.8%) and lethargy(95.6%) were the main symptoms.Laboratory examination showed that children with SAP were prone to increased white blood cell count, C-reactive protein, procalcitonin, aspartate aminotransferase, alanine aminotransferase and CK-MB, as well as decreased proportion of CD3 + , CD4 + , CD8 + , CD4 + /CD8 + and NK cells.The main complications intrapulmonary organ were respiratory failure(80.7%). The main complications extrapulmonary organ were circulatory complications (55.3%). SAP was easily combined with other pathogenic infections.Streptococcus pneumoniae(22.9%)was the most common bacterial pathogen.Respiratory syncytial virus(10.0%)were the most common virus, in addition, mycoplasma pneumoniae(17.1%) was also common.Multivariable Logistic regression analysis showed that the decreasing ratio of CD4 + /CD8 + and NK cells, congenital heart disease and congenital airway dysplasia were the independent risk factors for mixed infection of SAP in children( P<0.05). Conclusion:The SAP patients could easily suffer from mixed infection and high fatality rate.Immune dysregulation is the important risk factors for mixed infection of SAP in children.So immunoregulatory treatment is very important.
ABSTRACT
Objective:To investigate the efficacy and safety of bronchoscopic lavage in children with severe adenoviral pneumonia.Methods:Patients with severe adenovirus pneumonia who were admitted to ICU department of Hunan Children′s Hospital for bronchoscopy were collected from February to June 2019 and divided into lavage group( n=36) and non-lavage group( n=15) in line with whether lavage was performed.Their results, namely, bronchoscopic diagnosis, blood gas analysis before and 2 hours, 24 hours and 48 hours after bronchoscopy, improvement time of clinical symptoms(fever and pulmonary moist rales), the positive rate of pathogen detection and mortality rate, main vital signs such as heart rate, respiratory rate, mean arterial pressure and bronchoscopy-related complications were recorded before and 1 hour, 2 hours and 24 hours after bronchoscopy. Results:A total of 51 children were collected, all of whom suffered from endobronchitis.More secretions were observed in the airways of 36 patients in the lavage group, and only a little or no secretions were observed in 15 patients in the non-lavage group.P/F value and PCO 2 at 2 hours, 24 hours and 48 hours after treatment in the lavage group were improved comparing to those before treatment and were superior to those in the non-lavage group( P<0.05). P/F values at 24 hours and 48 hours after treatment in the non-lavage group increased and PCO 2 decreased at 48 hours after treatment( P<0.05). The thermal duration, time to resolution of moist rales in the lungs in the lavage group were shorter than those in the non-lavage group( P<0.05). The mortality rate in the lavage group was lower than that in the non-lavage group[2.8%(1/36) vs.26.7%(4/15), P<0.05]. The positive rate of pathogen detection in lavage group was higher than that in non-lavage group[55.6%(20/36) vs. 20.0%(3/15), P<0.05]. There was no significant difference in heart rate, respiratory rate, and mean arterial pressure at each time point before and after bronchoscopic treatment( P>0.05). Associated complications were 11 cases of intraoperative transient hypoxemia, four cases of bronchial mucosal bleeding, and one case each of postoperative hypoxemia, intraoperative hypertension and hypotension.There was no significant difference in the incidence of complications between the two groups( P>0.05). Conclusion:Bronchoscopic lavage, in treating children with severe adenovirus pneumonia, may improve clinical symptoms, respiratory function, and rate of pathogen detection, reduce mortality, and is effective and safe.
ABSTRACT
Objective:To explore the application value of heparin-binding protein (HBP) in the early diagnosis and assessment of severe adenovirus pneumonia.Methods:A total of 90 children diagnosed with adenovirus pneumonia admitted in the Department 1 of Emergency and Pediatric Intensive Care Unit 1 in Hunan Children′s Hospital from January 2019 to March 2020 were recruited.HBP levels in children with adenovirus pneumonia were detected.The correlation between HBP with white blood cell count (WBC), neutrophil ratio (N), C-reactive protein (CRP), interleukin-6(IL-6) and erythrocyte sedimentation rate (ESR) were examined.Receiver operating characteristic(ROC) curve analysis was conducted to explore the value of HBP in the early diagnosis and assessment of severe adenovirus pneumonia.Children with adenovirus pneumonia were divided into severe adenovirus pneumonia group (severe group) and non-severe adenovirus pneumonia group (non-severe group) according to their severity.Those in the severe group were further divided into bronchiolitis obliterans(BO) group and non-BO group according to the occurrence of BO.Results:(1) The HBP level in children with adenovirus pneumonia was (49.47±34.19) μg/L, which was significantly higher in the severe group than that of non-severe group[(82.88±44.02) μg/L vs.(35.15±13.08) μg/L, t=15.349, P<0.05]. Children in the severe group were significantly younger, and they had a significantly longer length of stay, lower Pediatric Critical Illness Scores (PCIS), and higher inflammatory markers like HBP, WBC, N, CRP, IL-6, and ESR compared with those of the non-severe group (all P<0.05). No significant difference in the procalcitonin (PCT) level was detected between groups.(2) The HBP was positively correlated with inflammatory markers like WBC ( r=0.38, P<0.05), N ( r=0.26, P<0.05), CRP ( r=0.47, P<0.05), IL-6 ( r=0.76, P<0.05), and ESR ( r=0.35, P<0.05). However, HBP did not have a significant correlation with PCT ( r=0.097, P>0.05). (3) In the severe group, the HBP level of the children with invasive mechanical ventilation, oxygenation index(P/F index)≤ 200 mmHg (1 mmHg=0.133 kPa) and BO was significantly higher than that of the non-invasive mechanical ventilation, P/F index> 200 mmHg and non-BO (all P<0.05). (4) The area under the ROC curve of HBP, WBC, N, CRP, ESR and IL-6 in predicting the severity of adenovirus pneumonia were 0.915, 0.748, 0.770, 0.740, 0.820 and 0.798, respectively.When the cut-off value of HBP was 45 μg/L, the sensitivity and specificity of HBP were 81.48% and 85.71%, respectively. Conclusions:As an inflammatory mediator, HBP is involved in the inflammatory response of the body.It may be a useful new marker for the early diagnosis of severe adenovirus infection, which also has a certain value in the evaluation of the severity and prognosis of the disease.The findings provide a basis for early clinical intervention and treatment of adenovirus infection in children.
ABSTRACT
Objective:To investigate the efficacy and safety of dexmedetomidine in noninvasive continuous positive airway pressure(NCPAP)for acute respiratory failure in children.Methods:Clinical data of children with acute respiratory failure who underwent NCPAP from January 2018 to March 2020 in PICU of Hunan Children′s Hospital were prospectively collected.They were randomly divided into dexmedetomidine group(group D)and midazolam group(group M), with a total of 100 children.We compared the sedation depth of the two groups at 7 time points after sedation at 0.5 h(t1), 1 h(t2), 2 h(t3), 6 h(t4), 12 h(t5), 24 h(t6), and 48 h(t7), time to reach proper sedation, NCPAP time, NCPAP failure rate, oxygenation index(P/F value)before sedation(T0)and 1h(T1), 24h(T2), and 48h(T3)after sedation, and the main vital signs and adverse reactions before sedation(T0)and 1h(T1), 24h(T2), 48h(T3)after sedation.Results:(1)The proportion of proper sedation at T4, T5, T6 and T7 after sedation in group D was higher than that in group M[98%(49/50)vs.84%(42/50), 94%(47/50)vs.90%(45/50), 96%(48/50)vs.88%(44/50), 90%(45/50)vs.88%(44/50), χ2=6.538, 8.043, 8.174, 7.678, all P<0.05]. Time to reach proper sedation in group D was shorter[(58.6±7.9)s vs.(66.7±9.3)s, t=4.682, P<0.01]. (2)The treatment time and failure rate of NCPAP in group D were lower than those in group M[(134.9±25.5)h vs.(147.8±24.3)h, 10%(5/50)vs.28%(14/50), all P<0.05]. P/F after NCPAP treatment in the two groups was improved as compared with that before treatment(all P<0.01), and the improvement was more significant in group D than in group M at T2 and T3 after sedation[(199.3±26.1)vs.(188.5±24.2)mmHg, (212.2±25.4)mmHg vs.(200.8±24.8)mmHg, t=2.132, 2.278, all P<0.05]. (3)There were no significant differences in heart rate(HR), mean arterial pressure(MAP), and respiratory rate(RR)before sedation between the two groups(all P>0.05). HR and RR after sedation in both groups decreased as compared with those before sedation( P<0.01). HR at T1, T2, and T3 after sedation in group D decreased more significantly than that in group M[(116.3±17.6)bpm vs.(124.8±14.1)bpm, (110.2±18.4)bpm vs.(121.9±15.2)bpm, (108.5±18.7)bpm vs.(117.6±12.8)bpm, t=0.479, -3.474, -2.840, all P<0.05]. There was no significant difference in RR after sedation between the two groups( t=1.872, 1.632, 1.675, all P>0.05). MAP at T1 in group D decreased as compared with T0( P<0.01). MAP at T1 in group D was lower than that in group M[(65.5±5.1)mmHg vs.(68.0±5.7)mmHg, t=-2.297, P=0.024]. (4)There was no significant difference in the incidence of total adverse reactions between the two groups[20%(10/50)vs.14%(7/50), P=0.595]. The incidence of bradycardia was higher in group D than in group M[16%(8/50)vs.2%(1/50), P=0.031]. Conclusion:The incidence of adverse reactions of dexmedetomidine and midazolam in the sedation of NCPAP in children with acute respiratory failure is similar, but the sedative effect of dexmedetomidine is better than that of midazolam in the improvement of pulmonary oxygenation.
ABSTRACT
Esophageal cancer is one of the common malignancies of the digestive tract, and its exact etiology and pathogenesis have not been completely clear. The establishment of animal model of esophageal cancer provides support for the basic and preclinical research of esophageal cancer, which is of great significance for further study to clarify the pathogenesis and explore the development of new therapeutic drugs. At present, the animal models commonly used in the study of esophageal squamous cell carcinoma mainly include chemical induction model, heterotopic transplantation model and orthotopic transplantation model. With the continuous progress of animal research on human origin tumor, the human transplanted tumor model has been more and more widely used. No matter which model has its own advantages and disadvantages and applicability, should be selected according to the purpose of the experiment. In this paper, the research progress on animal models of esophageal squamous cell carcinoma in recent years is reviewed, and the models commonly used in scientific research and preclinical treatment are discussed, which may provide a theoretical basis for the clinical treatment.
ABSTRACT
Objective@#To investigate the effect of oral nutritional supplements(ONS) on body weight loss and life quality in post-discharge patients with gastric and colorectal cancer.@*Methods@#All the enrolled post-operative gastric or colorectal cancer patients were randomly divided into ONS group and control group. Body weight loss, middle arm circumference, triceps skinfold thickness and right-hand grip strength were measured and the Karnofsky score, ECOG score and QOL score were calculated 3 months after the discharge.@*Results@#The body weight loss of gastric cancer patients was lower in ONS group than in control group since 2 months after discharge.(2 months after discharge: 1.65±2.11vs. 2.70±1.90 kg, t=-2.385 3, P=0.019 3; 3 months after discharge: 1.95±2.75vs. 3.67±2.29 kg, t=-3.134 7, P=0.002 4), There was no difference of body weight loss between two groups in colorectal cancer patients. The middle arm circumference, triceps skinfold thicknessand right-hand grip strength showed no statistic difference between two groups both in gastric and colorectal cancer patients. The Karnofsky score(56.82±13.65%vs. 51.71±9.72%, t=2.014 8, P=0.047 2) and QOL score(41.91±6.92 vs. 38.39±8.77, t=2.059 7, P=0.042 6) were higher in ONS group than in control group in gastric cancer patients. While all 3 types of scores had no difference between two groups in colorectal cancer patients.@*Conclusion@#ONS can efficiently reduce the body weight loss and improve the performance status and life qualityin post-discharge gastric cancer patients, but not in colorectal cancer patients.
ABSTRACT
Objective@#To investigate the relationship between sleep beliefs and attitudes and sleep quality in patients with stable coronary heart disease.@*Methods@#Totally 390 patients with stable coronary heart disease were investigated by the Pittsburgh Sleep Quality Index (PSQI), Dysfunctional Beliefs and Attitudes about Sleep Scale-16(DBAS-16) and a general information questionnaire which was designed by researchers.@*Results@#48.2% of patients with stable coronary heart disease reported poor sleep quality at home, and the total score of PSQI was (7.99 ± 4.061), the total score of DBAS was (47.44 ± 9.77). Univariate anova showed that age (F=14.567, P<0.01), gender (H=16.657, P<0.01), marital status (F=4.706, P=0.031), job status (F=15.738, P<0.01) and the number of comorbid diseases (F=4.674, P=0.003),are factors affecting sleep quality. Pearson correlation analysis showed that there were significantly negative correlation between PSQI and DBAS (r=-0.260, P<0.01). Multiple Linear Regression showed that sleep beliefs and attitudes, gender, age, the number of comorbid diseases were influencing factors of sleep quality (R2=0.247, F=17.907, P<0.01).@*Conclusions@#The sleep quality at home in patients with stable coronary heart disease was closely related to sleep beliefs and attitudes. Nurses should pay more attention to the sleep quality of patients, correct their incorrect sleep cognition timely, and improve their sleep quality.
ABSTRACT
Objective@#To observe the effect of curcumin on myocardial mitochondrial related gene (mtATP6), high mobility group box 1(HMGB1) mRNA expression and plasma HMGB1 level in rats with sepsis, and to explore a new strategy for protection of myocardial injury in sepsis.@*Methods@#A rat sepsis model was established by cecal ligation and puncture (CLP). Thirty male Sprague-Dawley rats were randomly (random number) divided into the sham operation group (sham group), sepsis group (CLP group), and curcumin intervention group (Cur group), with 10 rats in each group. Rats in the Cur group were treated with curcumin by intraperitoneal injection at 100 mg/kg, and normal saline was injected into rats in the sham and CLP groups. Five rats were randomly (random number) sacrificed at 6 h and 24 h after modeling. The pathological changes of myocardial tissue were observed under light microscope. The levels of CK and CK-MB in serum were detected. The HMGB1 level in plasma was detected by ELISA. Real-time PCR was used to detect the expression of HMGB1 mRNA and mtATP6 in myocardial tissue. One-way ANOVA were performed in multigroup mean comparison, LSD-t test was used to compare the mean values of two samples, and P<0.05 was considered statistically significant.@*Results@#The pathological score of myocardial tissue in the Cur group was lower than those in the CLP group at 6 h and 24 h (P<0.05).

The expression levels of HMGB1 mRNA and mtATP6 in myocardial tissue of the CLP group were lower than those in the sham group at 6 h (P<0.05), while the expression levels of HMGB1 mRNA and mtATP6 in myocardial tissue of the Cur group were higher than those in the CLP group at 6 h, but the difference was not statistically significant (P>0.05).@*Conclusion@#Curcumin protects acute myocardial injury by affecting HMGB1 release and translocation down-regulation of extracellular levels and regulation of mtATP6 expression in CLP model rats.
ABSTRACT
Objective To investigate the effect of oral nutritional supplements (ONS) on body weight loss and life quality in post-discharge patients with gastric and colorectal cancer. Methods All the enrolled post-operative gastric or colorectal cancer patients were randomly divided into ONS group and control group. Body weight loss, middle arm circumference, triceps skinfold thickness and right-hand grip strength were measured and the Karnofsky score, ECOG score and QOL score were calculated 3 months after the discharge. ResultsThe body weight loss of gastric cancer patients was lower in ONS group than in control group since 2 months after discharge. (2 months after discharge: 1. 65±2. 11vs. 2. 70±1. 90 kg, t = -2. 3853, P = 0. 0193; 3 months after discharge: 1. 95±2. 75vs. 3. 67±2. 29 kg, t = -3. 1347, P = 0. 0024), There was no difference of body weight loss between two groups in colorectal cancer patients. The middle arm circumference, triceps skinfold thicknessand right-hand grip strength showed no statistic difference between two groups both in gastric and colorectal cancer patients. The Karnofsky score (56. 82±13. 65％vs. 51. 71± 9. 72％, t = 2. 0148, P = 0. 0472) and QOL score (41. 91±6. 92 vs. 38. 39±8. 77, t = 2. 0597, P = 0. 0426) were higher in ONS group than in control group in gastric cancer patients. While all 3 types of scores had no difference between two groups in colorectal cancer patients. Conclusion ONS can efficiently reduce the body weight loss and improve the performance status and life qualityin post-discharge gastric cancer patients, but not in colorectal cancer patients.
ABSTRACT
Objective To investigate the efficacy and application of bronchoalveolar lavage in chil-dren with severe pneumonia undergoing mechanical ventilation. Methods Using a prospective randomized controlled clinical study, 202 children with severe pneumonia received mechanical ventilation in Hunan Children′s Hospital from January 2016 to January 2018 were selected as the subjects. According to the digital method,all cases were divided into treatment group (101 cases) and control group (101 cases) randomly. The patients in the control group were given conventional treatment ( anti-infection and symptomatic thera-py) . The treatment group was treated with bronchoalveolar lavage on the basis of conventional treatment. The basic situation,the respiratory function before and after the treatment,the inflammation index,the curative effect and the prognosis of two groups were analyzed. Results There were no significant differences between the two groups in gender,age,course pre-admission,pediatric critical illness score,respiratory function and in-flammation index ( P>0. 05 ) . The respiratory function indexes of the treatment group were obviously im-proved 2 hours after the treatment and the PaO2 ,PaO2/FiO2 and SaO2 were significantly higher than those of the control group[PaO2:(82. 4 ± 6. 4) mmHg(1 mmHg=0. 133 kPa) vs. (74. 0 ± 5. 5) mmHg, PaO2/FiO2:(360. 2 ± 21. 3) mmHg vs. (332. 6 ± 23. 5) mmHg,SaO2:(94. 9 ± 8. 2)％ vs. (88. 6 ± 10. 3)％], while the PaCO2 were significantly lower than the control group [ ( 37. 3 ± 10. 3 ) mmHg vs. ( 45. 8 ± 5. 5 ) mmHg],and the differences were statistically significant (P<0. 05). Five days after treatment,the WBC, PCT and CRP of treatment group were significantly lower than those in the control group[WBC:(8. 5 ± 2. 4) × 109/L vs. (11. 7 ± 3. 5) × 109/L,PCT:(1. 2 ± 0. 7) μg/L vs. (2. 3 ± 0. 9) μg/L,CRP:(9. 1 ± 3. 2) mg/L vs. (16. 5 ± 4. 7) mg/L,P<0. 05,respectively]. The total effective rate in the treatment group was significantly higher than that in the control group[93. 1％(94/101)vs. 81. 2％(82/101)]. Mechanical venti-lation duration and PICU stay in treatment group were significantly shorter than those in the control group [(148. 5 ±30. 6)h vs. (159. 6 ±47. 3)h,(220. 8 ±49. 7)h vs. (330. 7 ±94. 6)h]. The positive rate of patho-genic bacteria was significantly higher than that in the control group [79. 2％(80/101)vs. 62. 4％(63/101), P<0. 05],but there was no significant difference in the 28 days mortality of the two groups[5. 0％(5/101) vs. 5. 9％(6/101),P>0. 05]. Conclusion The bronchoalveolar lavage can improve the respiratory func-tion,reduce the inflammatory reaction,shorten mechanical ventilation duration and PICU stay in children with severe pneumonia undergoing mechanical ventilation obviously. It is worth popularizing in the PICU because of the improvement of curative effect in these children.
ABSTRACT
Objective To investigate the relationship between sleep beliefs and attitudes and sleep quality in patients with stable coronary heart disease. Methods Totally 390 patients with stable coronary heart disease were investigated by the Pittsburgh Sleep Quality Index (PSQI), Dysfunctional Beliefs and Attitudes about Sleep Scale-16(DBAS-16) and a general information questionnaire which was designed by researchers. Results 48.2% of patients with stable coronary heart disease reported poor sleep quality at home, and the total score of PSQI was (7.99 ± 4.061), the total score of DBAS was (47.44 ± 9.77). Univariate anova showed that age (F=14.567, P＜0.01), gender (H=16.657, P＜0.01), marital status (F=4.706, P=0.031), job status (F=15.738, P＜0.01) and the number of comorbid diseases (F=4.674, P=0.003),are factors affecting sleep quality. Pearson correlation analysis showed that there were significantly negative correlation between PSQI and DBAS (r=-0.260, P＜0.01). Multiple Linear Regression showed that sleep beliefs and attitudes, gender, age, the number of comorbid diseases were influencing factors of sleep quality (R2=0.247, F=17.907, P＜0.01). Conclusions The sleep quality at home in patients with stable coronary heart disease was closely related to sleep beliefs and attitudes. Nurses should pay more attention to the sleep quality of patients, correct their incorrect sleep cognition timely, and improve their sleep quality.
ABSTRACT
Objective To observe the effect of curcumin on myocardial mitochondrial related gene (mtATP6), high mobility group box 1(HMGB1) mRNA expression and plasma HMGB1 level in rats with sepsis, and to explore a new strategy for protection of myocardial injury in sepsis.Methods A rat sepsis model was established by cecal ligation and puncture (CLP). Thirty male Sprague-Dawley rats were randomly (random number) divided into the sham operation group (sham group), sepsis group (CLP group), and curcumin intervention group (Cur group), with 10 rats in each group. Rats in the Cur group were treated with curcumin by intraperitoneal injection at 100 mg/kg, and normal saline was injected into rats in the sham and CLP groups. Five rats were randomly (random number) sacrificed at 6 h and 24 h after modeling. The pathological changes of myocardial tissue were observed under light microscope. The levels of CK and CK-MB in serum were detected. The HMGB1 level in plasma was detected by ELISA. Real-time PCR was used to detect the expression of HMGB1 mRNA and mtATP6 in myocardial tissue. One-way ANOVA were performed in multigroup mean comparison, LSD-t test was used to compare the mean values of two samples, andP<0.05 was considered statistically significant.Results The pathological score of myocardial tissue in the Cur group was lower than those in the CLP group at 6 h and 24 h (P<0.05). The CK and CK-MB in the Cur group were lower than those in the CLP group at 6 h and 24 h (P<0.05). The levels of HMGB1 in the Cur group were lower than those in the CLP group at 6 h and 24 h (P<0.05). The expression levels of HMGB1 mRNA and mtATP6 in myocardial tissue of the CLP group were lower than those in the sham group at 6 h (P<0.05), while the expression levels of HMGB1 mRNA and mtATP6 in myocardial tissue of the Cur group were higher than those in the CLP group at 6 h, but the difference was not statistically significant (P>0.05).Conclusion Curcumin protects acute myocardial injury by affecting HMGB1 release and translocation down-regulation of extracellular levels and regulation of mtATP6 expression in CLP model rats.
ABSTRACT
Objective To compare the contents of hospital information disclosure in China and the United States, and provide reference to improve hospital information disclosure in China. Methods Systematic collection was made for hospital information disclosure data from government documentation, statistical yearbooks, and hospital website portals like Hospital Compare of the United States and China. By means of inductive method and comparative analysis, hospital's medical services that were openly and freely accessible to the public of the two countries were studied in terms of structural indexes, medical quality indexes and patient experience assessment. Results The disclosed structure indexes of the US were abundant and distinctive. Its disclosed medical service quality indexes include such four diseases as myocardial infarction, cardiac failure, pneumonia and childhood asthma, as well as classification indexes under surgery infection prevention, comprising ten core process indexes and nine outcome indexes. In addition, the US also discloses patient experience survey results of ten aspects. Given the rich hospital information structure openly accessible in China, there lacks medical service quality information for disclosure. The only information directly comparable was the ranking of hospitals and specialties, instead of patient experience results. Conclusions China can learn from the experiences of American hospital information disclosure, establish an easy-to-understand and comparable index system; enrich the disclosure content, and build an authoritative and unified disclosure platform.
