Objective To explore the effect of high positive end-expiratory pressure (PEEP) for the treatment of neurological pulmonary edema (NPE) in patients undergoing mechanical ventilation,and to look for the best mechanical ventilation strategy to improve the prognosis.Methods A prospective study was conducted,and 120 patients with NEP admitted to Department of Critical Care Medicine of the First Affiliated Hospital of Guangxi Traditional Chinese Medical University from January 2010 to August 2013 were enrolled and divided into two groups according to random number table (n=60 in each group).The patients in two groups were given empiric treatment for the disease,and they underwent mechanical ventilation.In the normal PEEP group PEEP was 3-10 cmH2O (1 cmH2O =0.098 kPa),and in the high PEEP group PEEP was 11-30 cmH2O,and all the rest parameters were the same.Clinical indices before and 7 days after treatment,and 28-day morality rate were compared between two groups.Results The 28-day morality rate in high PEEP group was obviously lower than that in the normal PEEP group [25.0％ (15/60) vs.65.0％ (39/60),x2=6.465,P=0.011].The clinical signs in both groups were improved after treatment.Compared with the normal PEEP group,the clinical indices in high PEEP group were more significantly improved.There were significant differences in body temperature (℃ 37.4 ± 0.5 vs.38.5 ± 0.6),respiratory rate (times/min 18.3 ± 3.1 vs.23.3 ±3.5),heart rate (beats/min 94.7 ±8.5 vs.113.5 ±8.0),white blood cell count [WBC (× 109/L) 12.5 ±2.1 vs.17.1 ± 1.7],acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score (15.6 ± 3.2 vs.19.8 ± 3.7),Glasgow coma score (GCS 12.5 ± 2.1 vs.8.5 ± 2.9),gastrointestinal dysfunction score (3.9 ± 3.0 vs.3.6 ± 2.4),oxygenation index [PaO2/FiO2 (mmHg,1 mmHg=0.133 kPa) 196.5 ± 45.1 vs.134.1 ± 22.3],serum creatinine [SCr (μmol/L) 86.5 ± 35.6 vs.98.5 ± 37.7],total bilirubin [TBil (μmol/L) 39.7 ± 23.5 vs.41.5 ± 16.2],C-reacting protein [CRP (mmol/L) 53.7 ± 21.4 vs.108.4 ± 26.3],prothrombin time [PT (s) 15.0 ± 2.1 vs.20.4 ± 2.2],activated partial thromboplastin time [APTT (s):37.3 ±4.9 vs.56.7 ± 13.6],international normalized ratio (INR 2.52 ±0.64 vs.4.01 ±0.77),extra vascular lung water index [EVLWI (mL/kg) 7.53 ± 1.21 vs.15.85 ±3.41],pulmonary vascular permeability index (PVPI 6.07 ± 0.89 vs.9.47 ± 1.26),mean arterial pressure [MAP (mmHg) 87.3 ± 10.9 vs.98.7 ± 13.6],cardiac output [CO (L/min) 7.15 ± 1.42 vs.5.65 ± 1.82],systemic vascular resistance index [SVRI (KP) 112.4 ± 9.5 vs.136.5 ± 11.9],and blood lactate (mmol/L:2.53 ± 1.23 vs.5.81 ± 2.17) between high PEEP group and normal PEEP group (P＜0.05 or P＜0.01).Conclusion Prognosis can be improved in NPE patients with the use of high PEEP in mechanical ventilation.

Objective To discuss the diagnostic value of the lumbar intervertebral disc degeneration by CT scanning.Methods The clinical representation and CT view of 809 cases with degenerative lumbar intervertebral disc were retrospectively analyzed.Results According to the different CT representation character,the degenerative lumbar intervertebral disc may be divided into the lumbar intervertebral disc denaturation bulge in 96 cases and the lumbar intervertebral disc herniation in 713 cases.Conclusion CT scanning is a value method to diagnosing degenerative lumbar intervertebral disc.

Objective To improve the knowledge of lumbar posterior marginal cartilagionous node.Methods CT findings of lumbar posterior marginal cartilaginous node in 52 cases were analyzed.Results Three CT characters were:summarized cartilagionous node,centrum posterior marginal osseous absence and protruding follicle ring fragment.Conclusion CT scanning hes defiuite diagnositic value for the lumbar posterior marginal cartilaginous node.

Objective To improve recognition of the processus articularis arthropathy.Methods CT findings of the processus articularis arthropathy was analysed.Results According to the CT findings of the 94 cases processus articularis arthropathy,CT signs and the syndrome of this disease were summarized five types:①zygapophyseal hypertrophy and osteophyte formation;②stricture or asymmetry of articular space ;③vacuum phenomenon of articular space ;④pachynsis or calcification of articular capsule ;⑤articular instability.Conclusion The processus articularis arthropathy is a very high incidence of a disease.The CT scanning is very important significance to the disease.

Objective To study the clinical effects of Ditan Xingnao Chengqi soup for treatment of patients with sepsis brain dysfunction. Methods Sixty-two cases of sepsis brain dysfunction were divided into treatment group(32 cases)and control group(30 cases)according to random digits table. Both groups received general clinical treatment,while the treatment group additionally accepted Ditan Xingnao Chengqi soup through nasal feeding. The changes of C-reactive protein(CRP)of two groups before treatment and after treatment for 12,24,48,72 hours and 1 week were observed. Besides,the Glasgow Outcome Scale(GOS)was used to assess the curative effect of two groups, and its clinical significance was judged. Meanwhile,the hospitalization costs,the times staying in hospital and total effective rates of the two groups after treatment were observed. In addition,cost-effectiveness analysis was carried out. Results With the extension of therapeutic time,the levels of CRP(mg/L)in the two groups were reduced effectively in comparison with those before treatment,and the change was more obvious in the treatment group;after treatment for 24 hours,the difference in the level of CRP between the two groups began to be statistically significant(106.5±22.3 vs. 201.6±25.4,P<0.05). The GOS of two groups after treatment had been increased markedly in comparison to that before treatment,and the change was more obvious in treatment group(72 hours:10.34±0.76 vs. 7.34±0.48,1 week:13.16±0.86 vs. 9.56±0.64,both P<0.05). Hospitalization costs(yuan)of treatment group in intensive care unit (ICU)was lower than that in control group(43276.16±1844.23 vs. 51347.75±2011.06,P<0.05),and the duration of staying(day)in ICU of treatment group was shorter than that in control group(15.11±2.25 vs. 20.30±2.97,P<0.05). The total effective rate of treatment group was higher than that of control group,but the difference had no statistical significance(87.5%vs. 60.0%,P>0.05).The ratio of cose effectiveness analysis in treatment group was smaller than that of control group(497.42 vs. 855.80,P<0.05). Conclusions Ditan Xingnao Chengqi soup has a relatively good effect on antagonizing inflammatory factors,controlling excessive inflammatory response and improving disturbance of consciousness. The early intervention with this agent for a patient with sepsis cognitive impairment can control the disease situation,improve the patient's prognosis and reduce his or her hospitalization costs.

Objective To discuss the application value of MSCT in the diagnosis of acute appendicitis.Methods 30 patients with appendicitis were enrolled as a research group,meanwhile 30 healthy adults without any diseases were as a control group.Some MSCT findings were observed or measured including diameter and position of appendix,fluid and gas density in appendix cavity, periappendicural fat density and peritoneal thickening,ascites and so on.Results The outside diameter of acute appendicitis appen-dix was (9.78±2.33)mm on average,whereas the diameter of normal adults appendix was (5.05±0.53)mm,exhibiting a signifi-cant difference (t=24.85,P <0.01).Rough periappendicural fat with increased density in 25 patients (83.33%)with the CT value of about -40 to 20 HU,exudation and peritoneal thickening around the appendix in 13 (43.33%),thickening and edematous appen-dix walls in 29 (96.67%),fecal stone in the appendix cavity with high density in 9(30.00%),the appendicitis in combination with intestinal obstruction in 1 (3.33%),and the appendicitis with peritoneal thickening in 80.00% and with peritoneal effusion in 23.33%were found in the study.Conclusion Full abdominal MSCT can help to the diagnosis of acute appendicitis,and some MSCT findings can be useful for the diagnosis including the appendix diameter≥6 mm,appendix cavity effusion,lumen stone,peripheral increased adipose density and peritoneal effusion.
