Objective To investigate parenteral nutrition and enteral nutrition therapy for esophageal cancer patients nutritional status improvement.Methods Totally 63 patients with esophageal cancer were chosen,preoperative Nutritional Risk Screening 2002 (NRS2002) nutritional screening through joint after parenteral nutrition and enteral nutrition therapy.Patients with intestinal tolerability and complications after surgery on days 1 and 7 days nutrition indicators were observed,including total serum protein,albumin,prealbumin,hemoglobin,and lymphocyte count.Results Preoperative risk malnutrition occurred in 39 patients.Compared to patients on day 1 after the first 7 days,serum levels had no significant difference in total protein.Albumin,prealbumin,hemoglobin,and lymphocyte counts were significantly different statistical significance (P ＜ 0.05).Conclusions NRS2002 for nutritional screening patients at risk of malnutrition can be determined,and the combined parenteral and enteral nutrition therapies can improve nutritional status of patients with esophageal cancer.

Objective To enhance the function of picture archiving and communication systems (PACS) and the efficiency of medical imaging by adjusting dataflow. Methods About 9500 examinations consecutive data in July of 2003 were analysed and and followed. The dataflow was adjusted by adding digital radiology servers and temporal servers. Results The network bottleneck was resolved and the system load balanced, then the function of the system was enhanced. The secure running of the system was ensured in condition of urgency or increasing of patients and image data. Conclusion Adjustment of dataflow in PACS makes full use of all resources, reduces unnecessary time-wasting , further improves the working efficiency in our department.

Aim To explore the antioxidation of pergolide on rat models of Parkinson disease and its mechanism. Methods Wistar rats were pretreated daily with pergolide(1.0 mg?kg -1,ip),pergolide combined with sulpiride(25 mg?kg -1) or sulpiride alone for 7 days, and then sacrificed by decapitation. The activity of SOD and GSH in striatum was determined. Unilateral Parkinsonian models were made in rest of the rats by stereotaxically injecting 6-OHDA. After two weeks, apomorphine (APO)-induced rotational behavior of each group was compared, and the concentrations of striatal dopamine (DA),dihydroxyphenyl acetic acid(DOPAC) and homovanilic acid(HVA) were determined by high performance liquid chromatography (HPLC). Result Administration of pergolide for 7 days significantly increased the act- ivities of SOD and GSH in the striatum (P

AIM: To compare the contents of baicalin,paeoniflorin and glycyrrhetic acid in the seperated and mixed decoction of Huangqin Decoction(Radix Scutellariae,Radix Paeoniae alba,Radix et Rhizoma Glycyrrhizae and Fructus Jujubae). METHODS: The contents of baicalin,paeoniflorin and glycyrrhetic acid were analyzed by HPLC.Chromatographic conditions included: Hypersil BDS C_(18) column and the mobile phase consisted of a mixture of methanol-water-phosphoric acid(47(∶)53(∶)0.2),acetonitrile-water-phosphoric acid(18(∶)82(∶)0.1) and methanol-water-phosphate buffer solution(70(∶)29(∶)1).Baicalin,paeoniflorin and glycyrrhetic acid were detected at 280 nm,230 nm and 250 nm respectively. RESULTS: The linear range of baicalin,paeoniflorin and glycyrrhetic acid were 2.88—72.00 ?g/mL,2.85—22.80 ?g/mL and 4.16—52.00 ?g/mL respectively.The contents of baicalin in the mixed decoction was higher than that in the seperated decoction.The contents of paeoniflorin and glycyrrhetic acid in the mixed decoction were almost as same as that in seperated decoction. CONCLUSION: The contents of active ingredients in the mixed and seperated decoction are different.

MicroRNA (miRNA) are small non-coding RNA that act at the post-transcriptional level, regulating protein expression by repressing translation mRNA target. They can be detected in plants, animal species and viruses, and are involved in numerous cellular processes. MicroRNA-155 (miR-155) which is a kind of microRNAs expressed in hematopoietic cells. Recent data indicate that MiR-155 plays a key role in the pathogenesis of hematological malignancies through regulating cell signal transduction pathways of cell proliferation, differentiation and apoptosis, acting predominantly as an oncomir. MiR-155 may be an important indicator to assess the diagnosis, treatment and prognosis of patients with hematological malignancies, including malignant lymphoma, acute myeloid leukemia, and myelodysplastic syndrome. It could be suggested that drugs such as antisense oligonucleotides able to down-regulate miR-155 expression would provide a novel, and possibly specific way to control the growth of a range of haematopoietic malignancies in conjunction with classical cytotoxic therapy. The purpose of this review is to summarize current findings on the role of miR-155 in hematopoietic malignancies and, moreover, to highlight their role as potential therapeutic tools.

OBJECTIVETo study the genetic determination of fast plasma glucose (FPG) and correlation with its potential correlated traits, anthropometric measures and blood pressure.

METHODSTwo hundred and eighteen Type 2 diabetes mellitus (T2DM) pedigrees composed of 1383 Chinese Han individuals residing in the East and South-East China were analyzed. Univariate variance decomposition analyses were used to estimate the narrow-sense heritability (h(2)) of FPG, anthropometric indices and blood pressure, and bivariate quantitative genetic analyses were used to estimate the genetic and environmental correlations between FPG and anthropometric measures or blood pressure.

RESULTSWe found that FPG, blood pressure and all anthropometric indices except for waist to hip ratio were under significant genetic determination, and the h(2) was from 0.28 to 0.43. We did not find significant genetic and environmental correlation between FPG and anthropometric indices and blood pressure.

CONCLUSIONThe present study demonstrated that T2DM, obesity and hypertension were controlled by some genetic factors, and FPG shares little common genetic and environmental factors with obesity-related anthropometric indices and blood pressure in our Chinese sample population.
