Carefully evaluation of cardiovascular function in children with septic shock is the basis of appropriate therapy.Clinical methods of cardiovascular function evaluation include clinical manifestation,hemodynamic momtoring and laboratory test of tissue oxygenation.Evaluation of cardiovascular function should combine all results from different methods and should be dynamically monitored with the development of septic shock.

Mechanical ventilation is an important life support method.Correct parameter adjustment of mechanical ventilation depends on assessment of Patient's respiratory and the effectiveness of mechanical venfilation.Blood gas monitoring is the most important way to assess the effectiveness of mechanical ventilation.Guidance of blood gas monitoring in parameter adjustment of mechanical venfilation is the key of successful mechanical ventilation.

Objective:to study alexithymia of long-term survivors of cancers. Method:to compare 36 long-term survivors of cancers and 45 normal controls with TAS (Toronto alexithymia scale) and SCL-90.Result:there was no significant difference between the two groups in total score of SCL-90. But the survivors had significant higher score in TAS than controls.Conclusion:although long-term survivors are similar in symptom level to normal control, they still have obvious alexithymia.

Purpose:To study the efficacy and the toxic side effects of high dose epirubicin containing combination regimen in the treatment of advanced breast cancer. Methods:16 patients with advanced breast cancer were treated with epirubicin (EPI) 100 mg/m 2,CTX 600 mg/m 2,5 FU 500 mg/m 2,every 21 days,Each patient was given at least 2 cycles. Results:There were 2 CR and 9 PR, the overall response rate was 68.8% (11/16). Main side effects were grade Ⅰ—Ⅱ leucopenia, nausea and vomitting, alopecia.Conclusions:This study confirmed that combination chemotherapy with high dose epirubicin is a safe and effective regimen for patients with advanced breast cancer and is worthy of further clinical trial.

Objective To explore the clinical features of nephrotic syndrome combined with H1N1 influenza. Methods The clinical manifestations, laboratory and image examinations, treatment, and prognosis of nephrotic syndrome combined H1N1 influenza were retrospectively analyzed in 15 children with. Results All of 15 children with nephrotic syndrome met the diagnostic criteria of H1N1 influenza. The median age of all children was 4-year-8-month old (2-year-2-month to 6-year-9-month). All children were treated with hormone alone or combined with other immunosuppressive drugs. Three cases were severe and another 5 cases were critically ill. Four cases were complicated with recurrence of nephrotic syndrome, 2 of which suffered from acute renal insufficiency. All children were given oseltamivir as antiviral treatment at admission. Four cases took oseltamivir within 48 hours of onset and showed mild symptoms. Fourteen children with H1N1I influenza were cured, their urinary proteins were significantly decreased or converted to negative, and the median hospital stay was 8 days (1 to 25 days). One child died of acute necrotizing encephalopathy and brain herniation. Conclusions Children with nephrotic syndrome are susceptible to severe or critical H1N1 influenza infections. During the epidemic of H1N1 influenza, the clinical preventive measures should be taken in children with nephrotic syndrome.

OBJECTIVE: Small diameter vascular grafts (＜ 6 mm) are used predominantly in revascularization and reconstructive procedures. The small diameter vascular grafts already used in our clinical practice include autologous veins or arteries, polyethylene terephthalate (Dacron) and expanded polytetrafluoroethylene (ePTFE) synthetic vascular grafts. Unfortunately these vascular grafts all have some disadvantages that prohibit their uses. Therefore search for ideal small diameter vascular grafts has become the focus in recent years.DATA SOURCES: A computer-based online search of Pubmed database was undertaken to identify the articles about small diameter vascular grafts published in English between January 1990 and January 2007 with the key words of "prosthetic graft, vascular bypass graft, small diameter vascular graft, tissue engineering".STUDY SELECTION: The data were selected firstly to choose the full-text of articles met the criteria. Inclusion criteria: ① Articles about biological vascular grafts; ②Articles about synthetic vascular grafts; ③Articles about small diameter tissue engineering blood vessels. Exclusion criteria: Repetitive or analogical articles or case reports.DATA EXTRACTION: Totally 113 articles on small diameter vascular grafts were collected and 41 met the inclusive criteria after eliminated the repetitive or similar studies or case reports.DATA SYNTHESIS : Although biological vascular grafts have the outstanding advantages, such as superior long-term patency, relatively resistant to infection, minimal thromboembolism, etc., they also have predominant disadvantages of limited availability, durability and aneurysm formation. Dacron and ePTFE are currently the standard synthetic vascular grafts in the vascular bypass surgery, but their immediate or long-term patency rates are relatively poor due to compliance mismatch, thrombogenicity and poor haemodynamics, especially when they are used in small diameter revascularization and reconstructive procedures. Thus, various modifications have been applied to Dacron and ePTFE grafts to improve their function. In recent two decades, the emergence of tissue-engineering technology has made the development of a novel biologically viable vascular substitute feasible, and it may prove to be the ultimate solution for better small-diameter vascular grafting.CONCLUCTION: So far there is no completely biodegradable small diameter vascular graft suitable for the arterial circulation in humans. Construction of an ideal small-diameter vascular graft will require an interdisciplinary effort requiring critical contributions from biologists, engineers, and clinicians, with strong collaborations among these 3 fields being crucial to success.

Objective To investigate the role of fluid therapy in treatment of septic shock in children.Methods A total of 48 pediatric patients with septic shock were enrolled.Twenty-seven patients were treated with volume expansion and 21 patients were treated with fluid resuscitation.There were no differences in use of antibiotics,inotropic and vasoactive agent in two groups.The time needed for haemodynamic stability,occurrence of pulmonary edema.length of PICU stay,and mortality were compared between two groups.Results Compared with volume expansion group,the time needed for haemodynamic stability significantly decreased in fluid resuscitation group ((216.10± 168.13) minutes vs (121.63 ± 75.59) minutes) (P < 0.05). There were no significant difference in occurrence of pulmonary edema between volume expansion group and fluid resuscitation group (14.8% vs 9.5% . P > 0.05) .Compared with volume expansion group,length of PICU stay significantly decreased in fluid resuscitation group ((6.188 ±3.250) days vs (3.944±2.711) days,P < 0.05).Compared with volume expansion group,mortality significantly decreased in fluid resuscitation group (40.7% vs 14.3%,P < 0.05) . Conclusions Rapid fluid resuscitation was associated with early reach of haemodynamic stability,short stay in PICU,improved survival rate and no increase in the risk of complication in pediatric patient with septic shock.

Aim To investigate the molecular mechanisms of differentiation in human leukemia HL-60 cells induced by diallyl disulfide(DADS)using suppression subtractive hybridization(SSH).Methods In our privious study,the subtractive cDNA library was constructed successfully and efficiently. 30 clones were randomly analyed with restriction enzyme.The inserts of cDNAs were analyzed by restrictive enzyme EcoR I.Positive clones were sequenced and the homology of resulting cDNA sequences were analyzed through bioinformatics software Blastn.Results 18 clones contained 100～600 bp cDNA inserts.10 differantiation genes were obtained and involved in cell cycle,signal transduction,metabolism and RNA binding.And 3 of 10 genes,p21,STAT1 and CAMTA1 were up-regulated and detected by RT-PCR,the results matched with SSH.Conclusion sThere are tight correlation between the differentiation induced by DADS and three-upregulated gene:p21,STAT1 and CAMTA1.

To analyze the reasons of injuries during surgical practices and explore the hazards and the corresponding preventive measures. The surgical interns don't receive enough training of injury prevention. They don't pay enough attention to the occupational prevention and are not skilled in operation, which causes high rate of sharp edged instrument injuries. Therefore, a perfect plan of education, training and treatment must be made to reduce the occupational injuries and blood sourced diseases.
