Objectives:To observe the role of peri operational nutritional support in the old patients with gastrointestinal carcinoma. Methods: One hundred and seventeen cases of aged patients with gastrointestinal carcinoma were divided into two groups: nutritional support (NS) group and normal therapy(NT) group. The therapeutic effects of peri operational nutritional support were studied. Results: All patients survived. The rate of complication in group of NT was higher than that of NS group. The recovering time of the gut function after operation and average duration in the hospital of the NT group were longer than that in the NS group. The recovery of body weight, level of plasma albumen and nitrogen balance in NS group was faster than that of NT group. Conclusions:Peri operational nutritional support in the aged patients with gastroenterological carcinoma is of significance, improving the nutritional condition,enhancing the endurance from the surgical trauma and decreasing the rate of postoperative complication.

Objective To investigate the effect of transcutaneous electrical nerve stimulation (TENS) on baseline eyes-closed brain activation and on pain-related EEG activity when TENS is applied contralatarally to the hand of pain. Method 128-channel electroencephalography (EEG) was recorded in four conditions including baseline,heat pain test,TENS stimulation and contralateral TENS modulation in 15 right-handed healthy young males. The Short Form McGill Pain Questionnaire was employed to assess pain sensation. Fast Fourier Transformation analysis (FFT) was performed to calculate absolute EEG power spectra based on 7 bands spectrum. Results ① The fronto-central beta-1 activity was significantly enhanced by TENS compared to eyes-closed [eyes-closed:(290±201)μV2,TENS:(385±224)μV2,t=3.323,P<0.01].②TENS markedly relived pain sensation assessed by SF-MPQ and significantly increased the posterior-anterior alpha-1 power [pain:(332±221)μV2,TENS modulation:(378±243)μV2,t=3.683,P<0.01] and fronto-central and posterior beta-1 activities [pain:(348±213)μV2,TENS modulation:(397±240)μV2,t=2.362,P<0.05]. Conclusion TENS,used as a peripheral nerve stimulation,mainly activates sensorimotor cortex.The increased Alpha-1 activity implies that TENS is likely able to relieve pain affective.

Objective To study the renal protective effects of ulinastatin in rats with multiple organ dysfunction syndrome(MODS). Methods Thirty-six Wistar rats were divided into 3 groups:control group ,model group and treatment group. The MODS models were produced by injecting lipopolysaccharide(LPS) through the sublingual vein into the rats. Ulinastatin was injected into the sublingual vein of the rats in treatment group, LPS was injected into rats in the same way after 10 minutes. On the second hour and the sixth hour after treatment, serum and renal tissue samples were collected from the rats to determine the level of TNF-?,IL-6, IL-1?, iNOS by RIA.The pathologic changes of renal tissue was examined. Results The levels of TNF-?,IL-6, IL-1?, iNOS of serum and renal tissue in treatment group were obviously lower than in model group (P

Objective To compare the effects of oral Sildenafil(SIL)and intravenous prostaglandin E_1(Alprostadil,PGE_1)in treatment of postoperative pulmonary hypertension(PH)associated with congenital heart defects(CHD).Methods Data were collected from 24 children with postoperative mPAP≥35 mmHg in our hospital between August 2004 and March 2005.These children were randomly divided into three groups:8 children(group A)initially received SIL(0.35 mg/kg,orally by nasal gastric tube),followed by the addition of intravenous PGE_1(20 ng/kg per min)at 40 min.The second group of 8 children(group C)initially received intravenous PGE_1 followed by the addition of SIL at 20 min(dose as above).And remains(group B)were placebo-controlled.The changes of hemodynamic variables,arterial blood gas,lung static compliance(C)and work of breathing(W)were measured after drugs were given.Results Compared with group B,the mPAP and mPAP/mSAP was significantly reduced(P

Objective To study the reliability and validity of the Chinese version of the dynamic occupational therapy cognitive assessment for children (DOTCA-Ch).Methods The English version of the DOTCA-Ch was translated into Chinese. One hundred and nine students from the city of Jiamusi were assessed with the Chinese Binet intelligence test and the DOTCA-Ch. Intra-class correlation coefficients (ICCs) were used in inter-rater and intra-rater reliability assessments. Cronbach's alpha coefficient was used to assess internal consistency. Factor analysis was used to assess construct validity. Pearson correlation coefficients were used in assessing criterion-related validity. Results The total ICC of the DOTCA-Ch was 0. 892. Cronbach's alpha coefficients for the subtests were orientation 0. 713 ; spatial perception 0. 793 ; praxis 0. 850 ; visuomotor construction 0. 844 and thinking operations 0. 630. The ICC for intra-rater reliability was 0. 991 and for inter-rater reliability it was 0. 989. Using the Binet intelligence test as a benchmark, the Pearson correlation coefficient between the IQ values and the total DOTCA-Ch scores was 0. 872 for 6 year-olds, but 0. 870 for 11 and 12 yearolds. Factor analysis revealed an acceptable set of 5 common factors. Their cumulative contribution was 67％.Conclusions The Chinese version of the DOTCA-Ch is reliable and valid. It can be used as an effective measuring tool to evaluate children's cognitive functioning.
