Objective To study the difference in occurrence of complications and health economics between early enteral nutrition (EN) and total parenteral nutrition (TPN) in patients with alimentary tract carcinoma after surgical operation.Methods Totally,164 patients with alimentary tract carcinoma hospitalized at the Department of General Surgery in China-Japan Friendship Itospital,Beijing during September 2003 to December 2005 with nutritional intervention,84 cases with early EN and 80 with TPN within 24 to 48 hours after surgical operation,were reviewed.Nutrition index,complications,recovery of gastrointestinal movement,length of hospital stay after operation and total cost of the patients were analyzed. Results Serum level of prealbumin in EN group was (309?49) mg/L,significantly higher than that in TPN group of (277?46) mg/L (P

Objective To explore the effect of Dexamethasone(DEX)on the proliferation and the expression of fibroblast growth factor(FGF)- 1,FGF - 2 and interleukin - 6(IL - 6)mRNA in hyperoxia - exposed human em-bryo lung fibroblasts(MRC - 5). Methods High oxygen volume fraction of 950 mL/ L was used to establish hyperoxia -damaged cell models,then treated with different concentrations of DEX(10 - 4 ,10 - 6 ,10 - 8 ,10 - 9 ,10 - 10 ,10 - 11 ,10 - 12 mol/ L),respectively. The proliferation activity of the cells was evaluated by methyl thiazolyl tetrazolium(MTT)at 24 h,48 h,72 h,and the optimal hyperoxia - exposed time and concentration of DEX were chosen;then they were divided into air group,hyperoxia group and hyperoxia + DEX group. The mRNA expressions of FGF - 1,FGF - 2 and IL - 6 were detected by quantitative real - time PCR at 48 h. Results Cell proliferation activity of the hyperoxia group was lower than that of the air group and there were significant differences at 48 h and 72 h(all P ﹤ 0. 05). Compared with the hyperoxia group,cell proliferation activity of the hyperoxia + DEX group increased with the concentration of DEX decreasing,reaching the peak at 10 - 9 mol/ L,and then gradually decreased with the concentration of DEX decreasing. Cells were cultured for 48 h,compared with the air group,the level of FGF - 1 mRNA was lower,FGF - 2 and IL - 6 mRNA were higher in the hyperoxia group(P ﹤ 0. 05). Compared with hyperoxia group,the level of FGF - 1 mRNA was higher,FGF - 2 and IL - 6 mRNA were lower in hyperoxia + DEX group(P ﹤ 0. 05). Conclusions Exposure to high oxygen volume fraction of 950 mL/ L for 48 h can cultivate optimal hyperoxia - damaged cell models,and DEX can protect the cell from hyperoxia injury and 10 - 9 mol/ L was the optimal concentration. Enhanced the expression of FGF - 1 mRNA and inhibited expression of FGF - 2 mRNA may be one of the mechanism that DEX protects the cells from hyperoxia injury.

Objective To determine the risk factors and clinical features of mild vascular cognitive impairment due to subcortical small vessel disease (mVCI-SSVD).Methods Detailed demographic data,vascular risk factors, past and present history were collected and carefully neurological examination, National Institutes of Health Stroke Scale (NIHSS), as well as Hachinski ischemic score (HIS) were performed on 56 mVCI-SSVD patients.Further, the demographic data and vascular risk factors of mVCI-SSVD patients were compared with those of 80 normal control subjects.Results Proportions of smoking (39.3% (22/56)), hypertension (67.9% (38/56)), and diabetes (25.0% (14/56)) were higher in the patient group than in the normal control group (21.3% (17/80) , 47.5% (39/80), 11.3% (9/80)).Odds ratio (2.32(95% CI 1.05-5.13),2.15 (95% CI 1.02-4.54),2.26(95% CI 0.86-5.92)) between the two groups was statistically significant (P value: 0.039, 0.045, 0.047).There was no difference in terms of hyperlipidemia and cardiac disease between groups.Fifty percent (28/56) mVCI-SSVD patients had a clear stroke history.Twenty-six point eight percent (15/56) patients developed the cognitive impairment with an acute onset.Neurological focal signs presented in 20 patients (35.7%).Twenty four (42.9%) patients with HIS ≤ 4 points.Thirty eight cases (67.9%) scored 0 on NIHSS.Conclusions Current study suggested that smoking, hypertension, and diabetes may be risk factors for mVCI-SSVD.While hyperlipidemia and cardiac disease do not increase the risk of mVCI-SSVD.Unlike mVCI caused by large vessel disease, about half mVCI-SSVD patients lack of stroke history.Most patients show a relatively insidious onset and free of significant neurological focal signs.

A cardiac stimulator for rapid atrial pacing animal model was designed in this paper. According to the needs of clinical research, output pulse parameters of the cardiac stimulator can be designed. The cardiac stimulator will be controlled through magnet. Efficiency of the cardiac stimulator was validated by animal experiments.

Objective To approach the method for improving the intellectual development,of whom had suffered from parity′s brain damage.Methods The patients were divided into 2 groups randomly(age range from 7 days to 18 months) who were observed and compared for 3 years.Group A was bundle of intervention which had been under early intervention program since infant.Group B was bundle of comparing of which had not been under early intervention.Results Observed for 6 months and 12 months,the intellectual development of group A was prior to that of group B(age 6 months P

Objective:To investigate the expression of transforming growth factor ?1(TGF-?1) in dog mandibular distraction osteogenensis (DO). Methods: Mandibular DO model was established in 12 dogs and nonunion model in another 12 dogs, 4 dogs were used as the no-treatment control. Tissue samples were obtained 6 d,2 and 8 weeks after operation respectively.Immunohistochemistry and enzyme-linked immunosorbent assay (ELISA) were used to determine the expressions of TGF-?1 in the samples.Results: TGF-?1 (ng/g) in control group was 1394.3?20.1,6 d after operation that in DO and nonunion groups was 1928.5?33.5(vs control,P

Objective To observe the B- ultrasonic (B-US) renal changes of chronic aristolochic acid nephropathy (CAAN) patients and to determine its value in disease diagnosis. Methods The renal B-US data of 124 CAAN patients were retrospectively studied. The relationship between the B-US characteristics and the renal function was tested. Clinicopathological data of 19 CAAN patients underwent renal biopsy were compared with those of 18 patients with chronic tubulointerstitial nephropathy due to none-aristolochic acid causes (non-AAN-CTIN). Results The characteristics of renal B-US changes in CAAN patients included diminished parenchyma thickness (90.3%), atrophy of the kidney (62.90%) and asymmetrically shrinked kidneys (17.74%). The renal B-US markers, including the longitude, the volume and the parenchyma thickness, were closely associated with the level of Scr, eGFR and the function of renal tubules (P
