Objective To summarize extracorporeal membrane oxygenation (ECMO) in percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) with cardiac arrest,and to evaluate the clinical efficacy comparing with literature review.Methods 5 patients of AMI with cardiac arrest who proved invalid to conventional cardio-pulmonaryresuscitation (CPR),were successfully resuscitated with ECMO support,and underwent emergency PCI with stable hemodynamic status.Results In support of ECMO,4 patients were successfully resuscitated with stable hemodynamic status,and underwent primary PCI.The duration of ECMO support ranged from 42 to 220 h (average 126.6 h).3 patients discharged with full recovery,one patient didn't wean from ECMO successfully,and one died of respiratory failure.Conclusion Although mortality of AMI with cardiac arrest is high,early ECMO-assisted cardiopulmonary resuscitation and secondary PCI treatment increase the possibility of cardiac recovery,and provide conditions for emergency revascularization treatment.This reduces mortality in critical patients with AMI,and is an effective short term life support method.

Objective To observe the changes in cytokines, oxygen free radicals, acidulous production in serum and to investigate the effectiveness of monitoring metabolism of cells and the method for evaluating cell injury in patients with severe trauma. Method The detailed data of 117 patients rescued and managed carefully from May 2005 to February 2007 were assessed and stratified with ISS and APACHE Ⅱ , and the serum levels of arterial blood lactate(ABL) ,base deficit(BD) ,superoxide(SOD) ,lipid peroxide(LPO) ,TNF-α and IL-6 were measured in real-time according to the condition of the patient. Results The monitoring biomarkers obviously changed with injury severity which endangered the situation of patients after trauma (P < 0.05) , especially in the patients with ischemia , hypoxia, shock, iniection, SIRS, and MODS (P < 0.01). The persistence of extremely elevated levels of biomarkers meant the organ failure and fatality of patients after trauma, and there was a obvious differece between those cases and cases without elevation of biomarkers ( P < 0.01). Conclusions The outcome of patients after trauma is closely correlated with injury severity,infection and MODS,and the levels of biomarkers including ABL, SOD, IPO, TNF-a and IL-6 are useful indicators of outcome measure.

A thermal desorption ( TD) device was developed and coupled to gas chromatography ( GC) or gas chromatography-mass spectrometry ( GC-MS ) for the qualitative and quantitative analysis of semi-volatile organic compounds on atmospheric particulate matters ( PM ) . The TD was operated by direct heating and placed on the GC injector, leading to high heating rate and easy transfer of analytes to GC without focusing of analytes by cold trap. For establishing the TD-GC method, the materials used for supporting PM samples, temperature and time of thermal desorption, and types of sample injection were investigated for detection of sixteen polycyclic aromatic hydrocarbons ( PAHs) and nine n-alkanes. The limits of detection of the proposed TD-GC method were in the range of 0. 014-0. 093 ng for PAHs, and 0. 016-0. 026 ng for n-alkanes, respectively, with the correlation coefficients of correlation above 0. 9975. The TD-GC method was applied to the determination of trace PAHs and n-alkanes on PM10 samples from three cities. The recoveries were in the range of 95%-135% ( PAHs) and 95%-115% ( n-alkanes) , respectively. Finally, the TD was coupled to GC-MS for comparison of the contents of PAHs and n-alkanes on PMx with different particulate size ( x=10 , 5, 2, 1, 0. 5, 0. 25, 0. 1).

Objective To summarize the method and effects of extracorporeal membrane oxygenation (EC-MO) for eight patients with sever heart or(and) lung diseases,and to get some reliable advises by analysis of retro-spoctive indications,timing and result in ECMO therapy. Methods Eight patients,aging from 26 to 82 and weighted from 57-87 kg were observed. Vein-artery ECMO was used in all patients,with the flow in 40-70 ml/(kg·min) and the activated clotting time(ACT) kept at 160-200 s. Results The time of ECMO support varied from 9.5 h to 84.1 h;Among the eight patients,one didn't weaned from ECMO and died,two who were weaned died 38 h ,6 h af-ter ECMO;five patients weanned succsesefully from ECMO and discharged. Conclusions ECMO do well in treat-ment of severe cardiopulmonary failure, resuscitation and support post cardiosurgery,and the indication and timing performance are important to the final result.

Objective To explore the protective effects and the mechanisms of peritoneal dialysis (PD) on multiple organs induced by acute organophosphoms pesticide poisoning(AOPP)in order to get a scientific basis for the application of PD to treat AOPP patients. Method The model of AOPP rabbits was made by intragastric administration of 25 mg/kg(0.5LD50)40% omethoate, and the symptoms of poisoning such as myosis, salivating and muscular tremor were observed. Eighteen male Japanese rabbits were randomly divided into control group and peritoneal dialysis group (PD group). Pralidoxime chloride and atropine were given by intra-muscular injection to rabbits of control group (re = 9). Rabbits of PD group ( n = 9) had a tube inserted into peritoneal cavity and peritoneal dialysis was given for 10 times after administration of pralidoxim chloride and atropine. Serum TNF-α,CK-MB (M.B. isoerizyme of creatine kinase), ALT, creatinine, and amylase were observed dynamically. The dialysate of peritoneal dialysis was remained in the peritoneal cavity for testing the nature of intoxicant by using Varian 3900/ Saturn 2100T GC/MS device. All data were analyzed with SPSS version 12.0 software. Statistical comparison between two groups was carried out by using student t-test and analysis of variance(ANOVA) followed by Dunnett-ttests before and after intoxication. The pearson correlation analysis was used for determination of the relationship between TNF-α and other biomarkers. Results After intoxication, serum TNF-α, CK-MB, ALT and amylase increased except creatinine, but the serum levels of those biomarkers in PD group were significantly lower than those in control group.The level of TNF-a had positive correlations with CK-MB ( r = 0.470), ALT ( r = 0.649), and amylase ( r = 0.517). The omethoate was detected in the dialysate of peritoneal dialysis. Conclusions Organophosphorus pesticides can lead the cardiac muscle, liver, kidney and pancreas to the injury through several mechanisms,and the inflammatory mediators play important role in the development of MODS induced by AOPP. Peritoneal dialysis can clean up intoxicants slowly and continuously and in turn lower down the level of inflammatory mediators resulted in protecting multiple organs from AOPP.

ObjectiveTo investigate the biomechanical characteristics of different types of fixation with bioactive cervical fusion cage made of hydroxyapatite and poly L-lactic acid in cervical spinal fusion.MethodsIliac crest bone,bioactive cervical fusion cage and bioactive cervical fusion cage with plate fixation were used for anterior interbody implants after anterior discectomy across C5-6 in six fresh human cervical spine specimens respectively,and the range of motion of the cervical vertebrae interbody fusion were measured through the motional stability test.Results After discectomy,Bioactive Cervical Fusion Cage with plate fixation exhibited a significant increase in stability and a decrease of range of motion in angular motion than others in all motional directions ( P ＜ 0.005 ). Bioactive cervical fusion cage exhibited a decrease in stability and an increase of range of motion (6.25 ± 0.29) in angular motion than the intact spine (5.76 ± 0.40) in extension,but the difference was not significantly ( P ＞ 0.05 ).Bioactive cervical fusion cage exhibited a decrease in angular motion than iliac crest bone and a significant increase in stability in all motional directions except extension (P ＜ 0.005).ConclusionsBioactive cervical fusion cage' s biomechanical performance was excellent and bioactive cervical fusion cage with plate fixation was excellent in stability in all motional direction,and could remain initial stability of cervical vertebrae.

BACKGROUND:Distal radius C fractures belong to multiple fractures in the joint. Its treatment should recover various angles and joint surface continuity outside the joint. The recovery of palmar tilt angle, radial inclination angle and radial height is also very important for treating distal radius. OBJECTIVE:To study the changes in palmar tilt angle, radial inclination angle and radial height after type C fractures of the distal radius repaired with Acu-Loc(R)2 VDR bone plate system. METHODS:From May 2015 to March 2016, 11 cases of type C distal radial fractures were treated with Acu-Loc(R)2 VDR bone plate system. Preoperatively, the palmar tilt angle was-31° to-4° (-12.45° on average), and the radial inclination angle was 6° to 18° (11.18° on average), and the radial height was 1.92 mm to 8.68 mm (5.28 mm on average). X-ray films were observed at postoperative 4, 8 and 12 weeks and half a year in all patients. Palmar tilt angle, radial inclination angle and radial height were measured and observed using anteroposterior and lateral X-ray films during final follow-up. Wrist function was assessed with Gartland-Werley score. RESULTS AND CONCLUSION:(1) 11 patients were followed and the postoperative follow-up ranged from 7 months to 15 months. X-ray films showed that the union of fractures was achieved in 6-8 weeks (6.5 weeks on average). No infection or internal fixation failure occurred. The articular facets were smooth in 10 patients and a little poor was found in 1 case (<2 mm). (2) After operation, the palmar tilt angle was 8° to 15° (11.55° on average) (P<0.05);the radial inclination angle was 22° to 27° (23.18° on average) (P<0.05);the radial height was 8.01 mm to 13 mm (11.03 mm on average) (P<0.05). (3) The results were excellent in 8 cases, good in 2 cases, and poor in 1 cases according to Gartland-Werley wrist function assessment;the excellent and good rate was 91%. (4) Acu-Loc(R)2 VDR bone plate fixation can provide reliable fixation and effective support for type C distal radius fractures, which can recover the palmar tilt angle, the radial inclination angle and the radial height, so the Acu-Loc(R)2 VDR bone plate is an ideal method to treat type C fractures of the distal radius.

Objective: To unveil the efficacy of Shaolin internal qigong exercise in treating capsulitis of the shoulder (CS) and explore objective outcome measures by observing the changes in the surface electromyography (sEMG) signals of shoulder muscle groups after regular practice of Shaolin internal qigong exercise in CS patients. Methods: Sixty CS patients were randomized into two groups by the random number table method, with 30 cases in each group. Patients in the qigong group practiced Shaolin internal qigong exercise on a regular basis, while patients in the electroacupuncture (EA) group received EA treatment. Before and after treatment, the sEMG signals of six muscles, i.e. biceps brachii, triceps brachii, deltoid, pectoralis major, latissimus dorsi and trapezius muscles, of the affected side were recorded at 45° abduction of the shoulder, 60° forward flexion and 90° internal rotation with the elbow flexed during maximal isometric contraction, and the integrated electromyography (iEMG) of each muscle was calculated. Results: The total effective rate was 93.3％ in the qigong group, higher than 83.3％ in the EA group (P<0.05). Intra-group comparison showed that the iEMG of biceps brachii, triceps brachii, pectoralis major and deltoid muscles in the qigong group increased significantly after intervention at 45° abduction of the shoulder, 60° forward flexion and 90° internal rotation with the elbow flexed (all P<0.05), and the iEMG of trapezius and latissimus dorsi muscles decreased (both P<0.05); in the EA group, the iEMG of biceps brachii, pectoralis major and deltoid muscles increased significantly during contraction (all P<0.05), while the iEMG of triceps brachii, trapezius and latissimus dorsi muscles had no significant changes (all P>0.05). After intervention, there were significant differences in the iEMG of most of muscles between the two groups (all P<0.05), except for the iEMG of deltoid muscle at 45° of abduction of the shoulder joint during isometric contraction (P>0.05). Conclusion: Shaolin internal qigong exercise can effectively increase the motion intensity of the biceps brachii, triceps brachii, pectoralis major and deltoid muscles and reduce the compensation of the latissimus dorsi and trapezius muscles in CS patients; compared with EA, it produces a better result in improving the coordination and stability in shoulder joint movements.
