The physicians and nurses in the intensive care unit often discuss about withdrawing or withholding life-support therapy of critical ill patients with them or their family members.In this article,we expatiate on the importance,approach,agendas and medical ethical issues of the communication about end-of-life care between clinicians and families.

This paper reported the characteristics and regular patterns of the changes in computerized quantitative electrocncephalogram(EEGcq) and frontal electromyogram(EMGf) in 331 patients under the effect of various inhaled and intravenous anesthetics, and the changes in the EEGcq and EMGf during cerebral ischemia caused by serious hypotention or arrhythmia, feeble heartbeat, cardiac electromechanical dissociation and hypoperfusion during extracorporeal circulation. It was found that the amplitude of EEGcq decreased with a"suddenly coming and departing appearance"when the anesthesia with isofl-uorane was excessively deepened or the course of becoming light, that the EEGcq amplitude displayed on the screen showed frequent sharp uprisings when the anesthesia with enfluorane was excessively deepened, that the response of EMGf to various hurtful stimuli presented spikes when anesthesia was inadequate, and that the EMGf showed plateau tracings when the anesthesia was very light.

Vascular or endoluminal stent is a stent implanted in the lesion site to support stenosis vessels based on luminal balloon expansion,to reduce vascular elasticity recoil and remoulding,and maintain blood flow patent.Some stents can also prevent vascular restenosis.Stent size,surface coverage,radial supporting,extensibility,longitudinal recoil,fatigue test,material composition,corrosion-resistance,coagulation,surface roughness and biocompatibility(blood compatibility) are performance parameters to evaluate the stents.Vascular or endoluminal stent has been widely used in arterial and venous systems and non-vessel luminal systems.The incidence of complications following stenting is 11.6%,including acute or subacute thrombogenesis,restenosis,or stent dislocation.It is commonly demonstrated that intrastent restenosis is caused by hyperblastosis.

Objective To study the clinical therapeutic effect of acupuncture in the treatment of depressive neurosis.Methods The 60 selected patients of depressive neurosis were randomized into treatment group(acupuncture regulating the liver group)and con- trol group(near-by sham-point acupuncture group),with 30 in each.The scores of Symptom Checklist 90(SCL-90),Self-rating De- pression Scale(SDS),and Hamilton Depression Scale(HAMD),and the total effective rate after treatment were observed.Results The total effective rate of the treatment group and the control group was 92.6% and 56.0% respectively,and the difference was sig- nificant(P

Objective To investigate the relative risk factors of glucose metabolism disorder in newborn infants.Methods Clinical information of 791 newborns suffered from glucose metabolism disorders who had been hospitalized in NICU from Jan.2004 to May 2007 were analyzed retrospectively.Four hundred and thirty-nine cases presented with hypoglycemia,275 cases presented with hyperglycemia,and 77 cases presented with both hypoglycemia and hyperglycemia.Data of risk factors were processed with both ?2 test and multiple Logistic regression analysis.Results The statistic analysis showed that low birth weight[258 cases(58.77%)],asphyxia[217 cases(49.43%)],acidosis[146 cases(33.26%)],hypothermia[128 cases(29.16%)],maternal gestational hypertension[83 cases(18.91%)],pneumonia[63 cases(14.35%)],anomaly of placenta[35 cases(7.97%)],maternal diabetes[17 cases(3.87%)] and septicaemia[10 cases(2.28%)]were significant hypoglycemia risk factors(according to the level of morbidity).Pneumonia[98 cases(35.64%)],asphyxia[129 cases(27.23%)],hypoxemia[61 cases(22.18%)]and septicaemia[24 cases(8.73%)]were significant hyperglycemia risk factors.Acidosis[33 cases(42.86%)],pneumonia[27 cases(35.06%)]and maternal diabetes[6 cases(7.79%)] were significant risk factors for neonates with both hypoglycemia and hyperglycemia.Conclusion Dynamic monitoring of blood glucose concentration and reasonable adjustment is recommended for neonates with risk factors to lower morbility and mortality.

Objective To explore the occurrence of diaphragmatic muscle fatigue(DMF) in children with pneumonia and its relationship with respiratory failure.Methods One hundred and twenty-six cases of pneumonia(pneumonia group) and 60 healthy children(healthy control group) were selected,and 2K-V1 type intelligence electric impedance respirograph was used to measure diaphragmatic function of the children in both groups to find if the ribcage-abdomen motion was synchronic and to calculate M levels.The abdomen impedance values as X-axis were calculated,which were regarded,and the chest impedance values as Y-axis were calcaulated,which described two-dimensional chart of ribcage-abdomen motion curve and the ? angle which was between connection of maximum X value to the smallest X value and the X-axis were calculated.According to the changes of chest-abdominal curve in one-dimensional chart and the changes of M value and ? angle,the degree of the diaphragmatic muscle fatigue was judged.Results There were 98 cases of DMF in the 126 children with pneumonia,and 68 cases of which were type Ⅰ DMF,and 30 cases were type Ⅱ DMF.One-dimensional chart showed contradictory chest-abdominal respiratory motional curve,and two-dimensional chart moved in a clockwise direction.M value was(46.1?8.4)%,? angle was(136.7?12.0) degrees in children with type Ⅰ DMF;One-dimensional chart showed that the peak value of chest-abdominal respiratory motional curve dislocates,and two-dimensional chart moved in a counter-clockwise direction.M value was(17.2 ? 3.2)%,? angle was(48.2 ? 9.5) degrees in children with type Ⅱ DMF;the control group had M value(4.3 ? 1.0)%,? angle was(31.7 ? 5.2) degree.There were significant differences in M value and ? angle between type Ⅰ DMF children,type Ⅱ DMF children and healthy children(Pa
