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.

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

The pathogenesis of heart failure is a complex progression and associated with abnormal regulation of many signaling pathways. As a cofactor of hemoglobin, myoglobin, oxidative respiratory chain, DNA synthase and other important proteins, iron plays an indispensable role in myocardial energy metabolism. Recently, a large number of studies have shown that heart failure is related to the disorder of iron metabolism. Both iron deficiency and iron overload can lead to the development of a variety of cardiomyopathy, and even progress to heart failure. Iron metabolism could be a key target for the diagnosis, prevention and treatment of heart failure. Here, we review the basic process of iron metabolism and its mechanism in heart failure, expecting to provide new clues and evidence for the treatment of heart failure.

〔Abstract〕 Based on analyzing the background of generic drugs research and development, the paper elaborates the utilization meth-ods of drugs invalid patents, including information sources optimization and retrieval, invalid patents selection indexes and methods, in-fringement avoidance strategy.It takes the gastrointestinal stromal tumor drugs for example to find out drugs which can be imitated, pros-pects the future application of invalid patents information.

Prostate cancer is a common malignancy that affects men's health in the Western countries. Single nucleotide polymorphisms (SNPs), as the third generation of genetic markers, can influence the development, progression, and prognosis of prostate cancer. The same SNP may be related differently with prostate cancer among different races. This paper describes the relationship between SNPs and prostate cancer according to their related genes. SNPs can predict the risk of prostate cancer as well as the possible adverse reactions in its treatment, but at present they do have some limitations.

Objective To explore change of RBC[Ca2+]i levels in neonates with hypoxic-ischemic encephalopathy(HIE)and the influence of nimodipine on RBC[Ca2+]i and its clinical significance.Methods Fifty-eight neonates with moderate and severe HIE were randomly divided into 2 groups including routine treatment group(n=28)and nimodipine group(n=30),and 20 healthy full-term neonates were selected as healthy control group.Based on the routine treatment,nimodipine[2 mg,0.5-1.0 ?g/(kg?min)] was given intravenously in the nimodipine group for 7-10 days.Blood samples were collected before and after treatment for 72 hours and 10-14 days,respectively.The levels of RBC[Ca2+]i were measured by Fura-2 pentakis(acetoxymethyl)ester[Fura-2/AM].The results were analyzed by SPSS 10.0 software.Results 1.The levels of RBC[Ca2+]i in neonates with HIE were significantly higher than those in healthy control group[(2.83?0.36)mmol/L vs(2.15?0.18)mmol/L,P

?AIM:To investigate the causes and characteristics of retinal detachment after vitrectomy.?METHODS: Retrospective analysis of patients in our hospital in recent 4a who underwent primary, standard, three -port pars plana vitrectomy ( PPV ) . Retinal detachment occurred in 24 eyes ( 23 cases ) , 24-67 years old, average 49.0±12.0 years old.There were male in 17 cases, female in 6 cases, 6 right eyes, 18 left eyes.?RESULTS:Eighteen (75%) eyes without any symptoms were found during a routine check, 6 eyes ( 25%) with decreased visual acuity or in front of shadow.It took 1-223d from PPV to retinal detachment, average 40.7 ± 54.2d, of which retinal detachment occurred in 10 (42%) eyes within 1wk, 14 (58%) eyes within 1mo.The direct cause of retinal detachment was new retinal break ( a total of 27 holes ) in 19 eyes, proliferative vitreoretinopathy ( PVR) in 4 eyes, 1 eyes with primary hole not closed.All retinal detachment were ultimately completely reset.?CONCLUSION: The occurrence of new retinal breaks is the main cause of retinal detachment after vitrectomy, attention should be paid to the early postoperative peripheral retinal examination;after a timely surgery, the retina can be reset.
