ABSTRACT
Objective:To evaluate the effect of mechanical chest compression device in patients with cardiac arrest.Methods:The relevant literatures about mechanical cardiopulmonary resuscitation and manual cardiopulmonary resuscitation were systematically searched from China Knowledge Network (CNKI), VIP, Wanfang, PubMed, Web of Science and other databases. The effective data were extracted and analyzed by RevMan5.3 software.Results:A total of 20 clinical studies involving 29 727 patients were included, of which 11 104 patients received mechanical cardiopulmonary resuscitation and 18 623 patients received traditional manual cardiopulmonary resuscitation. The results of meta-analysis showed that mechanical cardiopulmonary resuscitation could not effectively improve the restoration of spontaneous circulation (ROSC) rate, admission survival rate, discharge survival rate and neurological prognosis in patients with cardiac arrest compared with manual cardiopulmonary resuscitation. ROSC occurrence rate ( RR=1.10, 95% CI: 0.99-1.23, P<0.01), admission survival rate ( RR=1.01, 95% CI: 0.95-1.08, P=0.67), discharge survival rate ( RR=1.00, 95% CI: 0.86-1.15, P=0.14), and good neurological function rate ( RR=0.81, 95% CI: 0.61-1.06, P=0.69) showed no significant differences between the mechanical cardiopulmonary resuscitation and manual cardiopulmonary resuscitation. Conclusions:Mechanical chest compression device has no advantage compared with manual cardiopulmonary resuscitation. Mechanical cardiopulmonary resuscitation is not recommended to completely replace manual chest compression in cardiopulmonary resuscitation.
ABSTRACT
Objective To evaluate the surgical treatment of complex acetabular fractures through the lateral-rectus approach with pelvic reconstructive plate and antegrade posterior-column lag screws.Methods Between January 2014 and April 2018,29 patients were surgically treated for complex acetabular fractures at Department of Orthopaedic and Trauma,Taihe Hospital.They were 22 males and 7 females,aged from 19 to 72 years(mean,41.7 years).According to the Letournel-Judet classification,there were 4 transverse fractures,7 T-shape fractures,15 both column fractures and 3 anterior plus posterior hemitransverse fractures.In all the patients,the lateral-rectus approach was adopted;their anterior column fractures were fixated with pelvic reconstructive plate and screws and their posterior column fractures with antegrade lag screws.The operation time,intraoperative bleeding,fracture reduction,fracture union time,function of the affected hip and complications were recorded.Results The operation time ranged from 50 to 140 min,averaging 85 min;the volume of intraoperative bleeding ranged from 150 to 1,100 mL,averaging 315 mL.By the Matta criteria,the reduction was rated as excellent in 21 cases,as good in 7 and as poor in one,giving an excellent to good rate of 96.6％.The average follow-up was 16.2 months (from 6 to 30 months) for the 29 patients.Their fractures got united after an average of 11 weeks (from 7 to 13 weeks).According to the Merle d'Aubigné & Postel scoring system at the last follow-up,the function of the affected hip was excellent in 20 cases,good in 7 and fair in 2,yielding an excellent to good rate of 93.1％.There was one case of vasospasm of external iliac artery.No such complications were observed by follow-up as infection,deep venous thrombosis,heterotopic ossification,osteoarthritis or avascular necrosis of the femoral head.Conclusions The lateral-rectus approach with pelvic reconstructive plate and antegrade posterior-column lag screws is a suitable surgical treatment for complex acetabular fractures,leading to satisfactory clinical results.The lateral-rectus approach provides adequate exposure of the quadrilateral surface and facilitates insertion of the posterior column antegrade lag screws.
ABSTRACT
With the increasing incidence of osteoporosis, osteoporotic vertebral compression fracture (OVCF) has become a common disease in the elderly. Relevant researches have indicated that percutaneous vertebroplasty (PVP) has become the main treatment for painful osteoporotic vertebral compression fractures. In aspect of perioperative nursing care for PVP, both domestic and foreign scholars have published a large number of research reports, indicating that perioperative nursing intervention can alleviate the pain, reduce the incidence of complications, improve the quality of life of patients, and promote rehabilitation. This article aims to make a comprehensive review about the perioperative nursing care for patients with osteoporotic vertebral compression fractures who are receiving PVP so as to provide reference for clinical nursing staff in the implementation of nursing intervention.

ABSTRACT
Objective To determine the value of oxygenation index in assessing the outcome of mechanical ventilated patients with acute respiratory distress syndrome (ARDS).Methods From September 2008 to September 2013,patients meeting the Berlin definition of ARDS were evaluated in this retrospective study.Data included oxygenation index (PaO2/FiO2) on day before,and day 1 and day 3 after mechanical ventilation.The levels of PaO/FiO2 on day before and day 1 after mechanical ventilation were compared between 28-day survivors and non-survivors.Results There were 236 patients meeting the criteria of the Berlin Definition for diagnosis and treated with mechanical ventilation.The mean score of APACHIE Ⅱ and sequential organ failure assessment (SOFA) at the beginning were (19.1 ± 3.0) and (10.8 ±2.5),respectively,while oxygenation index on day before mechanical ventilation was (150.3 ± 62.6) mmHg.According to the hypoxemia grade,patients were divided into mild (n =36),moderate (n =122) and severe (n =78) ARDS,and their levels of PaO2/FiO2 were (80.1 ± 8.1),(162.3 ± 19.9) and (261.6 ± 22.3) mmHg,respectively.There were 92 non-survivors and 144 survivors.No obvious difference in oxygenation index of non-survivors among on day before、and day 1 and day 3 after mechanical ventilation.There was statistically significant difference in oxygenation index between on day before and day 1 after mechanical ventilation in survivors (P ＜ 0.05).Compared with the survivors,the score of APACHE Ⅱ,SOFA,and oxygenation index on day 3 were associated with increased mortality in the non-survivors,respectively (P ＜ 0.05).In respect to the mortality,the cut-off point of score of oxygenation index set at ＜ 180 mmHg on Day 3,an area under the receiver operating curve (AUC) was 0.749 with statistically significance (P ＜ 0.05),leading to sensitivity 61.7％ and specificity 93.2％.The relationship between prognosis and antibiotic resistance did not have statistically significance.Conclusions Data of oxygenation index on early phage of ARDS may be valuable to predict the outcome.A strong predictor of adverse outcome in such conditions was the score of oxygenation index on Day 3 ≤ 180 mmHg.
ABSTRACT
Objective To study the effects of thrombolysis for the treatment of acute cerebral infarction (ACI) in early stage (within 6 hours after onset) in hospital, and to demonstrate the benefit of urokinase in the treatment of acute cerebral infarction. Method The patients with cerebral infarction treated with UK within 3hours after onset in the emergency department were enrolled as the study group, and those treated with thrombolytics in the neurological unit over the same period were taken as the control group. Results The average time from onset of ACI to starting thrombolytic therapy was 45 minutes in the study group and 80 minutes in the control group.The number of patients treated with thrombolysis within 3 hours was 39 ( 14.4% ) in the study group and 29 (10.5%) in the control group. There were significant differences in the scores of the National Institutes of Health Stroke Scale (NIHSS) after thrombolytic therapy and in Bathel index of complete or nearly complete recovery rate between two groups. The length of hospital stay was shorter in patients of the study group than that in the control group. Conclusions The thrombolytic treatment with urokinase employed to the patients in the early stage of acute cerebral infarction leads to better outcomes than that in the later stage.

ABSTRACT
A method for the determination of cinoxacin and nalidixic acid in human plasma by reverse-phase high performance liquid chromatography is introduced. The single separation system involves a RP-C18 column, a ultraviolet detector at 254 mn and CH3CN-CH3OH-0.01 mol/L HOOCOOH (30:5:65;pH 4.55). The influence of two kind of buffer (phosphate buffer and oxalate buffer) in mobile phase on the separation were studied. Oxalate buffer can improve tailing peak and decrease detection limits. Three pH values (pH 2.80,4.08,4.55) were studied, pH 4.55 can give best separation result. The detection limits of cinoxacin and nalidixic acid were 0.14 ng and 0.24 ng, respectively.
