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.

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.

Objective To observe the efficacy of rotavirus vaccine to children with rotavirus gastroenteritis.Methods The children with rotavirus gastroenteritis at the first time were divided into two group;One have been given oral rotavirus vaccine,the others haven't.The difference of illness severity,rate of hospital admission and duration of the illness were compared between two group.Results The duration of rotavirus gastroenteritis of the group which have been given oral rotavirus vaccine was shorter,illness severity was lower and need for hospitalization was reduced.There was significant difference between the two group(P

Objective To study the status of electrolyte imbalance in infant with moderate to severe malnutrition and discuss reasonable clinical therapy.Methods we examined serum level of electrolyte and analyse retrospectively.96 infants were divided into three group-pneumonia,diarrhea and mixed group,difference of electrolyte imbalance was compared within the three groups.Results Hypokalemia and hyponatremia were the major electrolyte imbalamce.60.4% had hypokalemia,55,2% had hyponatremia;the other imbalance,46.9% had hypochloremia,40.6% had hypocalcemia,32.3% had hypomagnesemia,30.2% had metabolic acidosis and 16.6% had metabolic alkalosis.Conclusions The pneumonia group was more likely to have hyponatremia,and the diarrhea group was more likely to have hypokalemia.Serum level of chloride fluctuated with the change of blood potassium.Hypomagnesemia and hypocalcemia were normal and were influenced by acid-base balance.Acidosis was more likely to be found in diarrhea group,and was metabolic in most situation.There was a trend of emerging metabolic alkalosis in severe dehydration patient.

Objective To study the blood pressure and cardiovascular conditions in kidney transplant recipients in order to prevent the cardiovascular complications in such patients. Methods The blood pressure and ECG were monitored day and night by noninvasive means for 86 patients after transplantation.The results were analysed and compared with the pretransplantation studies. Results Hypertension occurred in 55 out of 86 patients.There was a significant difference of average blood pressure and the occurrence of abnormal ST segment or T wave between day and night whereas no significant change was observed in blood CsA concentration,blood creatinine,serum cholesterol,blood sugar,triglyceride and K+,N+,Cl-,TCO 2,Ca 2+ ,etc. Conclusions Cardiovascular complications in kidney transplant recipients is related to the high blood pressure during night,the normal day-night blood pressure rhythm being violated.It is not related to the immunosuppresives used.

Objective To study on the thermic effect of food (TEF) of patients with chronic obstructive pulmonary disease(COPD).Methods Basal energy expenditure (BEE) of 12 male cases and resting energy expenditure (REE) of 11 male cases of COPD were detected by indirect calorimetry with metabolic cart. There were no significant difference in sex, age, height and body weight between two groups' e.g:TEF=REE-BEE.Results BEE and REE were 1114?208kcal/d,1433?136kcal/d respectively, the latter was higher 28% than BEE.Conclusion TEF increases significantly which may contributes to malnutrition and non-response to nutritional support in patients with COPD.

Guided by the innovation theory and ideology, the authors'hospital saw to it that the main line of innovative progress ran through the entire process of its development and set up a management engineering framework for innovation in six chief aspects. It managed to achieve “three firsts”, viz. the first to put forward in the domestic medical industry the suggestion of taking strategic actions so as to promote the construction of a clean and honest administration in the hospital; the first among hospitals of the armed forces to cultivate an “experimental plot” that partook of no money earmarked for national defense; and the first among large general hospitals at home to develop into a non profit hospital without government subsidies. It also attained remarkable results in the fight against SARS.

Objective To study the immune enhancing effect of arginine on patients with chronic obstructive pulmonary disease (COPD) complicated with malnutrition.Methods Thirty cases with COPD accompanied by malnutrition received nutritional support of total calorie intake of 1 5 times of resting energy expenditure (REE).Group A(n=12) received oral administration of 30g L-arginine per day as supplementation;Group B(n=18) were control subjects.Results The nutritional parameters such as TSF(triceps skinfold) thickness,PAlb(prealbumin),CHI(creatine height index) were markedly improved in Group A than Group B,TNF-?,CD 8 decreased and IL-2,NO(nitric oxide),IgG and CD 4 increased significantly in Group A(P

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　To modify the Guy's stone score system and evaluate the validation of the modified score system in grading the complexity of percutaneous nephrolithotomy (PCNL) and predicting the stone-free rate after PCNL.　Methods　The modified system comprises 4 grades:grade Ⅰ,solitary stone in mid/lower pole or solitary stone in the pelvis with simple anatomy; grade Ⅱ,solitary stone in upper pole or multiple stones (located in 2 or more 2 calyces) in a patient with simple anatomy or a solitary stone in a patient with abnormal anatomy; grade Ⅲ,multiple stones in patients with abnormal anatomy or stones in a caliceal diverticulum or partial staghorn calculus; grade Ⅳ,staghorn calculus or any stone in a patient with spinal injury or spine malformation ( e.g.spina bifida,scoliosis,lordosis) ; kidney dysplasia ( e.g.duplex kidney,horseshoe kidney).It was validated on a database of 145 PCNL procedures performed by a single surgeon in a stone center.The clinical outcomes were retrospectively assessed with multivariate analysis.Results Of the 145 PCNL patients,according to Guy's stone score system and the modified score system,there were 22 G1 cases (15.2％) and 22 SFR cases (100.0％) ; 27 G2 cases (18.6％) and 25 SFR cases (92.6％); 36 G3 cases (24.8％) and SFR(31,86.1％); 60 G4 cases (41.4％) and 49 SFR cases ( 81.7％ ).Showing that the modified Guy's stone score was more accurate in predicting stone-free rate after PCNL ( P ＜ 0.05 ).　Conclusions　The modified Guy' s stone score system can accurately predict the stone-free rate after PCNL than the old system.
