Objective To explore the therapeutical effects of enteral nutrition (EN) combined with panaxoside Rb1 on mouse modles of postoperative fatigue syndrome. Methods Totally, 72 male Sprague-Dawley mice were randomly divided into control group, model group, EN group, EN associated with high/middle/low dose panaxoside Rb1 groups (EHP group, EMP group, and ELP group, n = 12 in each group). Changes in body weight were measured before and after interventions. Learning and memory playback abilities, physical strength,and vim state were evaluate by Morris Water Maze test and Improved Tail Suspension test. Serum transferrin, prealbumin, fibronectin, and interleukin-2 levels were measured with ELISA. Serum albumin level was assayed with Bromcresol Green colorimetric technique. CD4 + and CD8 + proportions were assayed by flow cytometry. Results The body weight grew alternately in each group without significant differences ( P ＞ 0.05 ) except for model group.The latency period was significantly shorter in EN combined with panaxoside Rbl group than that in model group ( P ＜ 0. 05 ) , and the frequencies of crossing platform in EHP group and EMP group were significantly higher than those in model group ( P ＜ 0. 01 ). The areas of struggling above domain in EHP group and EMP group were significantly larger than those in model group ( P ＜ 0. 05 ), and the accumulated static time of rest in EHP group, EMP group, and ELP group was significantly shorter than that in model group ( P ＜ 0.05 ). Serum transferrin, prealbumin, fibronectin levels in EN combined with panaxoside Rb1 group were significantly higher than those in model group ( all P ＜ 0.05 ). The CD4 + T proportion and interleukin-2 level in EHP group, EMP group, and ELP group were significantly higher than those in model group (both P ＜0.05 ); however, CD8 + T proportion was not significantly different between three panaxoside Rbl groups and model group (P ＞ 0. 05 ). Conclusion EN combined with panaxoside Rb1 can improve postoperative fatigue syndrome in a dose-dependent way, which may be explained by the fact that it can strengthen the postoperative nutrition, restrain hypermetabolism, and increase immunity.

Objective To evaluate the value of acute kidney injury network (AKIN) criteria for predicting hospital mortality in post-cardiosurgery elderly patients. Methods From October 2006 to January 2007, the elderly patients who underwent coronary artery bypass grafting or valve replacement operation were enrolled in this study. The medical data included gender, age, operation type, perioperative hemodynamic parameters, urine output, biochemical parameters and outcome. Renal function was assessed according to the AKIN criteria, and severity of illness was determined after surgery by calculating Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ ) score. Results A total of 225 patients underwent cardiac surgery during this period, 169 patients were male (75. 1%), while 56 were female (24. 9%), mean age was (66. 7±5. 0) years old. The overall hospital mortality rate was 5.8% (13/225). According to AKIN criteria, there were 125 patients with acute kidney injury (55.6%), and the hospital mortality of stage 1, 2 and 3 patients were 2. l%(2/96), 9. 1% (1/11) and 50. 0% (9/18) respectively. A significant increase was observed in mortality based on AKIN criteria (P<0. 01). By applying the area under the receiver operating characteristic curve, the AKIN criteria had a good discriminative power. Conclusions Both the incidence and mortality rate of acute kidney injury in the post-cardiosurgery elderly patients are high, the AKIN criteria is a simple and valuable method with a good prognostic capability for evaluating acute kidney injury.

OBJECTIVETo observe the change of postoperative fatigue in rats after the effect of branched chain amino acid(BCAA) and associated antagonists on central neurotransmitter 5-HT metabolic pathway, and to investigate the role of 5-HT in the development of postoperative fatigue syndrome(POFS).

METHODSFifty SD rats were randomly divided into sham operation group(C group, n=10), model group(M group, n=10), L-type amino acid transporter inhibitor group(L group, n=10), 5-HT uptake inhibitor group(F group, n=10) and branched chain amino acids(B group, n=10). The rats in the C group and the M group were injected with normal saline, while other three groups were respectively injected with BCH, fluoxetine, BCAA(val:leucine:isoleucine=5:3:2), on preoperative 1 h, postoperative day 1, 2, 3, 4. The rats, except for those in the C group, underwent resection of 70% of the middle small intestine with end-to-end anastomosis. General status of the rats was observed before and after surgery. Morris water maze test, including the hidden platform test and search space test (detecting the learning ability of rats) and tail suspension test (detecting physical endurance of rats) were used to evaluate the degree of POFS from postoperative day 1 to day 7. Concentration of tryptophan(TRP), 5-HT, 5-hydroxyindoleacetic acid (5-HIAA) in different position of brain(hippocampus, striatum, hypothalamus) of rats were measured by high performance liquid chromatography(HPLC) at postoperative day 8.

RESULTSAs compared to the M group, other four groups showed better general condition and less fatigue. In the hidden platform test, M group showed the least time of crossing platform as compared to other four groups(all P<0.05). Meanwhile, M group and B group performed the longer incubation period than C group and L group(all P<0.05). In search space test, M group and B group showed less time of crossing platform, but there were no significant differences among the groups(all P>0.05). In tail suspension test, M group and F group showed lower score of physical strength than L group and B group(all P<0.05). Levels of TRP in the L, F, B groups were lower compared to the M group(all P<0.01) in brain tissue. The least concentration of striatum 5-HT was found in the C group but there were no significant differences among the M, L, F and B groups. Level of 5-HIAA in the M group, only in hypothalamus, was higher than that in the F group(P<0.05), but no significant differences between the M group and the L and B groups were found.

CONCLUSIONBCAA and associated antagonists (BCH, fluoxetine) can improve POFS by reducing the absorption of TRP that results in decreased synthesis of central 5-HT.

OBJECTIVETo investigate the prevalence and distribution characteristics of dyslipidemia among Shandong residents aged 18-69 years.

METHODSThe levels of triglyceride (TG), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), and total cholesterol (TC) were determined in fasting serum of 5 ml venous blood for subjects aged 18-69 years who were selected by multi-stage stratified cluster random sampling from 20 counties in July, 2011 in 140 counties of Shandong province. The prevalence of dyslipidemia, hypercholesterolemia, high blood LDL-C, low blood HDL-C and hypertriglyceridemia were analyzed by the complex weighting. The prevalence of dyslipidemia, hypercholesterolemia, high blood LDL-C, low blood HDL-C and hypertriglyceridemia were compared for different characteristics by Rao-Scott χ(2).

RESULTSThe prevalence of dyslipidemia among 15 350 subjects was 22.70% (3 572), with higher in males (26.91% (2 110/7 683)) than in females (18.41% (1 462/7 667)). The prevalence of hypercholesterolemia was 3.39% (n=582), with higher in Eastern Shandong (4.59% (185/3 704)). The prevalence of high blood LDL-C was 0.56% (n=94), with higher in Eastern Shandong (0.79% (32/3 074)). The prevalence of low blood HDL-C was 11.41% (n=1 789). The prevalence of hypertriglyceridemia was 13.02% (n=2 059), higher in urban residents (16.54% (814/4 804)) than in rural (11.52% (1 245/10 546)) (χ(2)=71.54, P<0.001). The difference between the prevalence of low blood HDL-C and hypertriglyceridemia was not significant among Eastern Shandong, Central-South and Northwest.

CONCLUSIONDyslipidemia rate was higher among adult residents in Shandong province. The rate was higher for men than for women. The prevalence of hypercholesterolemia and high blood LDL-C were higher in Eastern Shandong than the other areas. The hypertriglyceridemia and low blood HDL-C were two major types of dyslipidemia.

OBJECTIVETo screen differentially expressed genes and identify potential signaling pathway in Asian people with breast cancer.

METHODSFive gene microarray datasets of Asian people with breast cancer, GSE6367, GSE9309, GSE15852, GSE33447 and GSE45255, were downloaded from GEO. Microarrays with 318 breast cancer and 60 normal breast tissues were used for analysis of differentially expressed genes and pathway. 32 pairs of breast cancer patients' specimens were used to validate the differentially expressed genes by real-time PCR.

RESULTSAnalysis of the large sample of microarray data identified 436 differentially expressed genes in breast cancer tissues, while 259 of these genes were up-regulated and the other 177 down-regulated. Pathway analysis showed that metabolism-related signaling pathway may be involved in the development of breast cancer in Asian people. The expressions of KRT19, ADIPOQ, CFD, RBP4, LPL, ABCA8 and CD36 genes were confirmed by real-time PCR.

CONCLUSIONThis study shows differential gene expression profile and potential signaling pathway in Asian people with breast cancer. CD36 gene may be closely related to the Asian breast cancer. ABCA8 gene may be a new disease gene in Asian breast cancer.

A novel bioinspired phospholipid copolymer has been synthesized by the radical polymerization of poly2-Methacryloyloxyethylphosphorylcholine (MPC), stearyl methacrylate (SMA), hydroxypropyl methacrylate (HPMA) and trimethoxysilylpropyl methacrylate (TSMA). Contact angle results indicated that the coating surface rearranged to get a more hydrophilic surface at the polymer/water interface. The membrane mimic phosphorylcholine coating surface could resist the platelet adhesion and prolong plasma recalcification time significantly. Rapamycin was used as model drugs to prepare drug-eluting coating. The animal experiments showed that this novel drug-eluting stent could effectively prevent the phenomena of restenosis.
