Objective To evaluate prognostic significance of early lactate clearance rate for cardiogenic shock patients on extracorporeal membrane oxygenation(ECMO).Methods Forty-seven patients with cardiogenic shock supported by venoarterial ECMO were prospectively enrolled from May 2010 to May 2013.Arterial blood lactate at pre-ECMO support(0 h),at post-ECMO 6 hours(6 h) were measured and then 6 h lactate clearance rate was calculated.90 days after admission was the endpoint of research.Patients were divided into the survival group(n =25) and the death group(n =22).6 h lactate clearance rate was compared between groups.The 6 h lactate clearance rate for predicting death was evaluated by receiver operating characteristic(ROC) curves.The surviving curve was drawn using the Kaplan-Meier method,and the survival of the patients was analyzed by the Log-rank test.Factors influencing the prognosis were analyzed by applying the multiplelogistic regression analysis.Results The 6 h lactate clearance rate was higher in survivors than in nonsurvivors [(38.6 ± 15.1) ％ vs.(14.4 ± 13.8) ％,P ＜ 0.05].The area under the ROC curve of 6 h lactate clearance rate for predicting death was 0.869 ± 0.075 (95％ CI:0.753-0.991).The best cutoff point was 20.0％ with a sensitivity of 92.0％ and specificity of 85.0％.KaplanMeier survival analysis showed that 90 days survival rate of high lactate clearance rate group and low lactate clearance rate group were 66.7％ and 35.0％,with significant difference between the two groups(Log-rank test,P ＜ 0.05).Multivariate logistic regression analysis showed that 6 h lactate clearance rate (OR =3.156,95 ％ CI:2.326-7.253,P ＜ 0.05) was one of the independent risk factors associated with mortality of patients on ECMO.Conclusion Early lactate clearance rate could be used as an important maker for evaluating the prognosis of cardiogenic shock patients on ECMO.

OBJECTIVE To investigate the prevailing strains of pathogens of hospital acquired infections in ICU and their drug-resistances in order to provide treatment basis for critical and severe patients in fighting against infection.METHODS A retrospective investigation analysis was made for all the isolated bacteria as well as their drug-resistance in our hospital from Jan 2000 to Dec 2005.RESULTS Totally 869 bacterial strains were isolated which included 666 strains of G-bacteria(74.3%),and 230 strains of G+bacteria(25.7%).The G-bacteria included Pseudomonas aeruginosa,Klebsiella pneumoniase,Escherichia coli,Acinetobacter baumannii,etc,which were isolated mainly from respiratory tract.The G+ bacteria consisted of Staphylococcus and Enterococcus.Staphylococcus were mainly isolated from respiratory tract and Enterococcus from urinary tract.Bacteria were highly resistant to commonly used antimicrobials and demonstrated multi-drug resistance.The isolated rate of G+bacteria and drug resistance of G-bacteria to the commonly used antibiotics was increasing yearly.CONCLUSIONS The pathogens are mainly isolated from respiratory tract and the most are G-strains and multi-drug-resistant.The selection and use of antibiotics should be based on the results of drug-sensitivity tests.

This paper summarized nursing care in intra-hospital transfer of 13 critically ill patients with extracorporeal membrane oxygenation. The key points to guarantee safety of critically ill patients were establishing a well-trained professional team and developing standardized procedures,and applying checklist for ECMO Transfer. The key points in nursing were assessment and pretreatment,homogenized nursing during transfer and effective handover after transfer. As a result,six cases of avian influenza patients successfully completed CT ex-amination,five cases of lung re-transplant patients and two cases of lung transplant patients were successfully trans-ferred to the operating room.

Objective:To investigate the relationship between the degree of basilar artery stenosis and the short-term prognosis in patients with isolated pontine infarction.Methods:One hundred and thirty-seven patients with isolated pontine infarction within 1 month after symptom onset admitted to our hospital from April 2016 to April 2018 were consecutively included.Based on modified Rankin scale(mRS)socres, patients were divided into the good outcome group(mRS score≤2)and the poor outcome group(mRS score>2). Venous blood samples were taken for biochemical testing on admission or the next day.Baseline National Institutes of Health Stroke Scale(NIHSS)scores and demographic data were recorded and compared between the two groups.The degree of basilar artery stenosis was assessed by magnetic resonance angiography(MRA), and subjects were divided into the non-stenosis, mild stenosis, middle stenosis and severe stenosis subgroups.Results:There were 108 patients in the good outcome group and 29 in the poor outcome group.The baseline NIHSS score(2.71±0.22 vs.7.10±0.59, t=6.99, P<0.01)and total cholesterol[(4.29±0.101)mmol/L vs.(4.76±0.17)mmol/L, t=2.21, P=0.03]were lower in the good outcome group than in the poor outcome group.The proportion of patients without stenosis was higher(76 or 70.4% vs.5 or 17.2%, χ2=26.70, P<0.01)and the proportion of patients with severe stenosis were lower(4 or 3.7% vs.7 or 24.1%, P=0.002)in the good outcome group than in the poor outcome group.Binary logistics regression analysis showed that baseline NIHSS score( OR=1.658, 95% CI: 1.327-2.071, P=0.000)and degree of basilar artery stenosis( OR=2.071, 95% CI: 1.159-3.701, P=0.014)were risk factors for the short-term prognosis. Conclusions:The degree of basilar artery stenosis is a risk factor for the short-term prognosis in patients with isolated pontine infarction, and patients with severer stenosis will have a poorer prognosis.

Objective To investigate the prevalence of hypertension in Keshan disease endemic areas in China,in order to provide evidence for making the policy in hypertension prevention and control for the most disadvantaged people in China.Methods Using non probability sampling method,50 counties with the highest prevalence rate of Keshan disease were selected in the 13 provinces (municipalities and autonomous regions) investigated in the 2012 national monitoring of Keshan disease,and in each county 2 villages were selected as the survey sites.Survey respondents aged over 18 years old were selected as the survey subjects.The prevalence of hypertension in residents was investigated through questionnaire investigation and clinical physical examination.The diagnostic criterion for hypertension was based on the 2010 Chinese Guidelines for the Management of Hypertension.Results A total of 45 165 adults aged 18 years and older were surveyed and 12 329 patients with hypertension in total were found,and the prevalence rate of hypertension was 27.3％.Among which the prevalence of men and women was 27.4％ (5 163/18 868) and 27.3％ (7 166/26 297),respectively.The prevalence rates of hypertension increased with age (x2 =4 132.3,P ＜ 0.05).Among different categories of hypertension,the proportion of grade one hypertension was the largest [33.4％ (4 116/12 329)],and differences between different proportions were significant (x2 =1 586.0,P ＜ 0.05).Conclusions The prevalence of hypertension in Keshan disease endemic areas is significantly higher than the national average level.The prevention and control of hypertension in vulnerable groups in the rural areas and Keshan disease areas should be emphasized.

Objective To test whether the changes of partial end-tidal carbon dioxide pressure (PETCO2) during passive leg raising (PLR) predict fluid responsiveness in mechanically ventilated patients with septic shock.Methods Forty-two mechanically ventilated patients with septic shock admitted from January 2012 to November 2012 were prospectively recruited.Hemodynamic parameters monitored by a pulse indicator continuous cardiac output(PiCCO) device and PETCO2 monitored by an expiratory-CO2 device were studied at baseline,after PLR,and after volume expansion.Fluid responsiveness was defined as an increase in cardiac index (CI) of 15％ or greater after volume expansion.The correlation between PLR-induced CI change (△CIPLR) and PETCO2 (△PETCO2-PLR) was analyzed.The value of △PETCO2-PLR to predict fluid responsiveness was evaluated by receiver operating characteristic (ROC) curves.Results A total of 42 patients were enrolled in this study,of whom,24 had a CI increase of ≥ 15％ after volume expansion (responders).After PLR,CI and PETCO2 were both significantly increased in the response group compared with baseline [(21.4 ± 12.9) ％ of CI and (9.6 ± 4.7) ％ of PETCO2,P ＜ 0.05],while no significant changes were observed (P ＞ 0.05) in the non-response group.Both △CIPLR and △PETCO2-PLR were significantly higher in responder group than in the non-responder group (both P ＜ 0.05).△CI and △PETCO2 after PLR were strongly correlated (r =0.64,P ＜ 0.05).In responders after PLR,the area under ROC curve of △PETCO2-PLR was 0.900 ± 0.056 (95％ CI 0.775-1.000,P ＜ 0.05).An increase of ≥ 5％ in △PETCO2-PLR predicted fluid responsiveness with a sensitivity of 88.0％ and specificity of 88.2％.Conclusions The change of PETCO2 induced by passive leg raising is a non-invasive and easy way to predict fluid responsiveness in mechanically ventilated patients with septic shock.

Objective:To investigate the correlation between IL-10 and I1-17 expression levels in Mycoplasma pneumoniae pneumonia (MPP) and lung function.Methods:70 patients were included in this study.According to wheezing or not,they were divided into wheezing group and non-wheezing group.Another 30 healthy children were taken as a control group.After taking fasting blood 5ml,the serum IL-10 and IL-17 expression levels were detected by ELISA.The forced expiratory volume in one second (PEV1),peak expiratory flow (PEF) and forced vital capacity (FEV1 / FVC) of all subjects were detected.Results:The IL-10 expression level of the wheezing group were significantly different with that of the control group (P＜0.05) and that of the non-wheezing group (P＜0.05).The 1L-17 expression level of the wheezing group also had significant difference (P＜0.05) with that of the control group and non-wheezing group (P＜0.05).The IL-10 expression levels of wheezing and non-wheezing group all were lower than that of the control group.Whereas the IL-17 expression levels of wheezing and non-wheezing group all were higher than that in the control group.In addition,patients in wheezing group had higher PEV1,PEF,PVE1/FVC values than those in non-wheezing group,with significant difference (P＜0.05).The serum level of IL-10 expression of Mycoplasma pneumonia patients was positively correlated with PEV1,PEF and PVE1/FVC,while the serum level of IL-17 expression of Mycoplasma pneumonia patients was negatively correlated with PEV1,PEF and PVE1/FVC.Conclusion:The serum levels of IL-17 and IL-10 expression of Mycoplasma pneumonia children had close correlation with their pulmonary function.

Objective:To investigate the influence of bundled ligation of the pancreatic stump on postoperative pancreatic fistula (POPF) of distal pancreatectomy (DP).Methods:The retrospective case-control study was conducted. The clinical data of 60 patients with diseases in pancreatic body and tail who underwent DP in the Affiliated Hospital of Inner Mongolia Medical University from January 2011 to August 2018 were collected. There were 24 males and 36 females, aged from 19 to 68 years, with a median age of 45 years. Of the 60 patients, 36 cases undergoing dissection of pancreas with Endo-GIA stapler were allocated into non-bundled group, and 24 cases undergoing bundled ligation of the pancreatic stump with No.10 or No.7 suture at the site over 1 cm of the resection site before dissection of pancreas were allocated into bundled group. Observation indicators: (1) postoperative situations; (2) analysis of risk factors for POPF of DP. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test or ANOVA test. Measurement data with skewed distribution were represented as M (range).Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test. Univariate analysis was conducted using the chi-square test and multivariate analysis was conducted using the Logistic regression model. Results:(1) Postoperative situations: the amylase concentration, cases with biochemical fistula, cases with grade B pancreatic fistula, cases with complications, time to extubation, duration of postoperative hospital stay, total hospital expenses were (2 629±592)U/L, 14, 5, 7, (11.9±0.7)days, (13.6±0.7)days, (49 430±1 626)yuan in non-bundled group and (683±312)U/L, 3, 1, 2, (9.7±0.6)days, (11.3±0.5)days, (44 767±1 163)yuan in bundled group, respectively. There were significant differences in the amylase concentration, cases with biochemical fistula, time to extubation, duration of hospital stay, total hospital expenses between the two groups ( t=2.528, χ2=1.512, t=2.341, 2.311, 2.111, P<0.05), and there was no significant difference in the cases with grade B pancreatic fistula or cases with complications between the two groups ( χ2=1.512, 1.394, P>0.05). (2) Analysis of risk factors for POPF of DP. Results of univariate analysis showed that tumor diameter and bundled ligation of the pancreatic stump were related factors of patients undergoing pancreatic fistula after DP ( χ2=4.462, 5.061, P<0.05). Results of multivariate analysis showed that bundled ligation of the pancreatic stump was an independent influencing factor of patients undergoing pancreatic fistula after DP ( odds ratio=0.187, 95% confidence interval as 0.037-0.954, P<0.05). Conclusions:Bundled ligation of the pancreatic stump was an independent influencing factor of patients undergoing pancreatic fistula after DP. Bundled ligation of the pancreatic stump can effectively reduce the incidence of POPF, especially biochemical fistula, the time to extubation, duration of postoperative hospital stay and total hospital expenses, and promote patient recovery after DP.
