Objective To observe the changes of plasma pulmonary surfactant protein-A (SP-A) and serum ferritin (SF) in neonates with mechanical ventilation and its clinical significance in ventilation-induced lung injury (VILI).Methods The study was carried out in 36 neonates with mechanical ventilation and 31 neonates without mechanical ventilation .Plasma SP-A and SF levels in venous blood were mea- sured on 1,24,48,72 hours after mechanical ventilation and 24 hours after mechanical ventilation removal by Western-dot blot and radioimmunoassay (RIA).Plasma SP-A and SF levels of non-mechanical ventilation group were determined at the same time.Results Plasma SP-A levels in neonates on 24,48,72 hours after mechanical ventilation were significantly higher than those of non-mechanical ventilation group[( 2.20? 0.22)vs(1.97?0.29) ?g/L,(2.43?0.28)vs(1.94?0.33) ?g/L,(2.61?0.38)vs(1.80?0.34) ?g/L,respectively P

The absorption process is an important factor in determining the bioavailability of orally administered drugs. however, the absorption mechanism of many drugs is not clear. Caco-2 cell model is the best in vitro absorption model nowadays. It is widely used in the research on drug absorption process and absorption mechanism, especially in the aspect of traditional Chinese medicine absorption, the use of Caco-2 cell model has become the hot spot recently. Mo- reover, Caco-2 cell model is also applied in the research on drug metabolism. Therefore, Caco-2 cell model will become an important method in the research of drug absorption, and will be helpful to accelerate the process of new drug screening and development.

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

Objective: To apply the NRS2002 to screen the nutritional status of preoperative patients and investigate the nutrition support in the perioperation and clinical outcomes. Methods: 127 selective operational cases(including general surgery,thoracic surgery,gynecology and orthopedic) were recruited to adopte the NRS2002 which issued by CESPN in 2006,and the nutrition support,energy and nutriment in the perioperation,complications,length of stay and drug costs were investigated. Result: 30.7% patients needed nutrition support,with general surgery(28.3%) being higher than thoracic surgery(2.4 %),gynecology(0%) and orthopedic(0%).The nutritional risk in elderly,carcinoma,abdominal operation patients were 18.1%,19.7% and 18.1% seperately,which was higher than others(P

ObjectiveTo evaluate the effect of rehabilitation nursing in the peri-operative period of the first-stage combined anterior-posterior approach surgery in the sacral tumor resection.Methods15 patients with sacral tumor received psychological intervention, gastrointestinal preparation, exercises of perineum sphincter contraction and relaxation training before the operation. Changes of patients' vital signs and nerve function were observed after the operation, and rehabilitation training and instruction were performed.ResultsAll cases were followed up for 2～37 months. Except one case died of tumor transfered to lung, all of other cases had a satisfactory curative effect in the near future, and their local symptom released and the functions of urination and defecation were kept well.ConclusionRehabilitation nursing in the peri-operative period plays an important role in surgical treatment of sacral tumor. It affects the rehabilitation and function restitution obviously and can reduce the occurrence of complication effectively.

Objective:To explore the methods of emergency terminating refractory tachyarrhythmia.Methods:Data of 117 cases,Who received emergency termination of tachyarrhythmia in emergency department of Taihe Hospital in the last five years,Were summarized and revieWed.Results:All 117 cases With tachyarrhythmia Were successfully terminated in emergency.A total of 21 cases (17.9%)Were successfully terminated in emergency using tWo or more methods (12 cases With supraventricular tachycardia,five cases With ventricular tachycardia,one case With atrial flutter and three cases With atrial fibrillation),in these patients concluded as refractory tachyarrhythmia,five pa-tients (23.8%)Were terminated via synchronous electrical cardioversion.Conclusion:Termination of refractory tachyarrhythmia needs individualization treatment strategy,its treatment may be drugs first and then electrical car-dioversion,or electrical cardioversion directly if necessary.

Objective To investigate the role of human cytomegalovirus (CMV) in the occurrence of drug eruptions.Methods Peripheral blood samples were collected from 44 patients with drug eruptions (including 13 severe cases) and 50 healthy human controls.Taqman fluorescent real-time quantitative PCR (RT-PCR) was performed to determine the positive rate and load of CMV DNA in peripheral blood mononuclear cells (PBMCs).Enzyme-linked immunosorbent assay (ELISA) was conducted to detect anti-CMV IgM antibodies in sera.Results The positive rate of CMV DNA was significantly higher in the patients than in the controls (65.91％ (29/44) vs.28.00 ％ (14/50),x2 =13.552,P ＜ 0.05),significantly different among patients with severe drug eruptions (11/13),patients with mild drug eruptions (58.06％ (18/31)) and the controls (x2 =16.153,P ＜ 0.05).In addition,patients with severe drug eruptions showed a higher positive rate of CMV DNA compared with patients with mild drug eruptions (x2 =13.817,P ＜ 0.05) and the controls (x2 =7.237,P ＜ 0.05).CMV DNA load was significantly higher in the patients than in the controls ((28 183.829 ± 19 527.654) vs.(3 019.952 ± 1 760.952) copies,t' =8.517,P ＜ 0.05).No significant difference was found in CMV DNA load between patients with severe drug eruptions ((554 813.389 ± 722 642.498) copies),patients with mild drug eruptions ((13 290.558 ± 14 082.356) copies)) and the controls (P ＞ 0.05).The positive rate of anti-CMV IgM antibodies was similar between the patients and controls (13.64％ (6/44) vs.6.00％ (3/50),P ＞ 0.05),but significantly different among patients with severe drug eruptions (4/13),patients with mild drug eruptions (6.45％,2/31) and the controls (x2 =7.832,P ＜ 0.05),and significantly higher in patients with severe drug eruptions than in the controls (x2 =6.409,P ＜ 0.05).Conclusions CMV infection exists in patients with drug eruptions,and might be a factor associated with the initiation and aggravation of drug eruptions.
