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 relationship between neck circumference and metabolic syndrome(MS) and its components in type 2 diabetes Methods A total of 272 subjects with type 2 diabetes were recruited.According to the diagnostic criteria of MS,all subjects were divided into MS group and non-MS group.According to neck circumference tertile,all subjects were respectively divided into male and female of three groups to analyze the relationship between neck circumference and MS and its components.Male:Q1＜38.8 cm,Q2=(38.8-41.3) cm,Q3≥41.4 cm;female:Q1＜34.0 cm,Q2=34.0-36.3 cm,Q3≥36.4 cm.The optimal cut-off points of neck circumference were used to determine the MS by ROC curve.Results (1) Compared with non-MS group,subjects in MS group had significantly higher neck circumference((38.3±3.2)cm vs.(36.1±3.7) cm),waist circumference((94.1±8.4) cm vs.(82.7±10.8) cm),waist-hip ratio(0.93±0.06 vs.0.88± 0.08),body mass index ((26.2 ± 2.9) kg/m2 vs.(23.9 ± 3.5) kg/m2),fasting plasma glucose(9.0(6.7-11.5) mmol/L vs.7.7(5.9-10.2) mmol/L),systolic pressure(140(130-150) mmHg vs.130 (120-130) mmHg),diastolic pressure (80 (80-90) mmHg vs.80 (75-85) mmHg),triglycerides (1.9(1.4-2.8) mmol/L vs.1.2 (0.9-1.5) mmol/L),low-density lipoprotein cholesterol (LDL-C) ((3.3 ± 1.0)mmol/L vs.(3.0±0.9) mmol/L) and blood uric acid((322.7±90.1) mmol/L vs.(270.3±82.3) mmol/L),and the differences were significant(t or Z=-4.843,-8.622,-5.157,-5.592,-2.729,-5.723,-3.847,-6.856,-2.123,-4.545;P＜0.05).While the level of total cholesterol((2.7±2.8) mmol/L vs.(4.9±1.3)mmol/L) and high-density lipoprotein cholesterol (HDL-C) (1.0 (0.8-1.2) mmol/L vs.1.2 (1.1-1.5)mmol/L) were decreased,and the differences were significant (t or Z =-2.269,-7.068;P ＜ 0.05).(2)Compared with those with lowest tertiles(Q1 ＜38.8 cm) of neck circumference,male subjects with highest tertile (Q3≥41.4 cm) had higher level of waist circumference((97.8±8.6) cm vs.(89.9±8.5) cm),waist-hip rati (0.96±0.07 vs.0.93±0.06),body mass index((27.4±2.1) kg/m2 vs.(23.8±2.3) kg/m2),blood uric acid ((374.0±85.6) mmol/L vs.(305.8±73.6) mmol/L),and the differences were significant(P＜0.05).While age((52.1±10.7) years vs.(60.4±11.8) years) andHDL-C((1.0±0.3) mmol/Lvs.(1.2±0.5) mmol/L) were decreased,and the differences were significant (P＜0.05).Female subjects with higher tertile (Q3 ≥ 36.4 cm) had significantly higher level of waist circumference ((96.8 ± 10.1) cm vs.(79.5 ± 8.5) cm),waist-hip ratio(0.94±0.07 vs.0.86±0.06),body mass index((28.5±3.1) kg/m2 vs.(21.9±2.2) kg/m2),blood uric acid((295.2±94.3) mmol/L vs.(244.6±62.3) mmol/L),the frequency of MS(83.3％(40/48)vs.21.7％(10/46)) than with lower tertile(Q1＜34.0 cm).(3) Logistic regression analysis showed that neck circumference (β =0.187,P ＜ 0.001) was an independent risk factor of MS (y =0.187x-6.613).(4) The optimal cut-off points of neck circumference to MS were 40.1 cm (AUC =0.682,P=＞0.008) in male,and 35.3cm (AUC =0.766,P＜ 0.001) in female.Conclusion Neck circumference increases when type 2 diabetes patients with MS.Neck circumference is an independent risk factor for MS,which can be used as an indicator to evaluate MS.

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 retrospectively investigate the characteristics of patients with inflammatory bowel disease (IBD)in last 10 years in Kunming city. Methods Four hundred and thirty consecutive patients with IBD, who had hospitalized in 7 hospitals between January 1998 to March 2007, were investigated. Among them, 379 patinets had ulcerative colitis (UC) and 51 had Crohn's disease (CD). The patients who received coloscopy, histopathological and bariam enema examination accunted for 98.2%, 56.2% and 2.6% in UC group,respectively, and 72.5%,78.4% and 31.4% in CD group,respectively. The gender, age, occupation and the clinical manifestation of the patients, and the results of the colonoscopy and pathological examination were analyzed. Results Most of the UC patients were aged 30 to 39 years and 50 to 59 years with average age of (46.9±15.8) years, whereas CD patients were aged 20 to 29 years with average age of (41.6±17.2)years. The male and urban patients were predominat in both UC and CD groups. Mental workers were common in UC group. The symptoms of diarrhea (302,79.7%), abdominal pain (285,75.2%) and bloody stools (290,76.5%) were major events in UC patients, and those of abdominal pain (44,86.3%), diarrhea (28,54.9%) and weight loss (28,54.9%) were major events in CD patients. The coincidence ratio among colonoseopy, histopathology and bariam enema examinations was 88.4 % ( 329/372 ), 24.4 % ( 52/213 ) and 4/10 in UC patients, respectively, and 86.5%(32/37), 27.5%(11/40) and 75%(12/16) in CD patients, respectively. All of the UC patients were in active stage of disease,including 38.3 % in mild,42.2% in moderate and 19.5% in severe. In CD group, 7.8% was in relief stage and 92.2% in active stage,including 15.7% in mild,43.1% in morderate and 41.2% in severe.Conclusion The understanding of prevalence and clinical characteristics of IBD in last 10 years in Kunming city will be helpful in diagnosis and treatment of the disease.
