Objective To investigate the clinical effect of glutamine on parenteral alimentation in patients with severe craniocerebral injury in ICU. Methods 120 patients with severe brain injury in our hospital from November 2013 to November 2014 were selected as the research object.According to the random number table method, the 120 patients were divided into experimental group and control group, 60 cases in each group.The patients in the experimental group received glutamine parenteral nutrition support, while the control group received conventional parenteral nutritional support.The serum total protein, albumin, the complications and malnutrition-inflammation score(MIS) scores of the two groups were compared.Results The serum total protein and serum albumin levels of the experimental group post-treatment were significant higher than those in the control group (P<0.001).The complication rate in the experimental group was 15.0%, significantly lower than the control group of 55.0%(χ2 =21.099,P<0.001).The patients of normal MIS score in the experimental group were obviously superior to the control group ( 70.0% vs.33.3%, χ2 =16.151, P <0.001 ). Conclusion Adding glutamine to parenteral nutrition support therapy in the treatment of patients with severe craniocerebral injury can effectively improve the nutritional status after operation and strengthen nutrition support.

AIM To examine the effect and mechanism of emodin on intestinal movement of constipation model. METHODS The movement of charcoal powder and the absorption of D-xylose into serum were observed. The electrical p otential difference(PD) related to Na + and glucose transport was measured across the wall of rev erted intestinal sacs. RESULTS Emodin 0 1, 0 2 g?kg -1 incr eased markedly the rate of charcoal powder moving and inhibited the absorption of D-xylose into serum. Emodin 0 2, 0 4, 0 8 and 1 6 g?L -1 decreased PD when ther e was glucose. However, emodin had little effect when glucose was free. CONCLUSION Emodin promotes intestinal movement and this effect is related to Na +,K +-ATPase.

BACKGROUND: Vascular endothelial growth factor (VEGF) is a very effective way to make tissue engineer bone vascularization.However, because of expensive and short half-life, VEGF cannot maintain effective concentration in blood after injection. To resolve the problem effectively, gene transfection technique is used in this experiment to transfer human VEGF into seed cells-mesenchymal stem cells (MSCs) of tissue engineer bone and to make it secrete VEGF which could vascularize bone.OBJECTIVE: To explore the possibility of human vascular endothelial growth factor 165 (VEGF165) to transfect rabbit MSCs, and establish the experimental foundation of angiogenesis tissue engineering organization and the treatment of ischemic disorders.DESIGN: Observation control trail.SETTING: First Hospital of Jilin University and Institute of Frontier Medical Sciences of Jilin University.MATERIALS: The experiment was conducted in the Key Laboratory (BSL-2) of Frontier Medical Sciences of Jilin University between June 2003 and August 2004. Health New Zealand white rabbits, 4.0-5.0 months old, weighing 2.5-3.5 kg, half male and half female, were provided by Animal Center of Jilin University. The rabbits were handled under asepsis and anesthetized condition,corresponding to the animal ethical standard. Medicine and reagents: Ham F12 culture media (Gibco, U.S), MTT (Sigma, U.S)PLXSNKDRp-VEGF165 and pcDNA 3.0 vectors were prepared in the present laboratory. ELISA detection kit (Jingmei company,Shenzhen), DH5 α, restriction endonucleases Barn H I, Xhol Ⅰ, Hind Ⅲ, EcoR Ⅰ and standard DNA molecule (Promega,U.S) were also used in this study.METHODS: Rabbits' MSCs were separated and cultivated. The pcDNA 3.0-hVEGF165 expression vector was constructed and identified, pcDNA3.0-VEGF165 eukaryotic expression vector was constructed, the vector was used directly to transfect MSCs. The cultural supernatant then was collected and the soluble protein of human VEGF gene expression was analyzed with ELISA method.The proliferation capability of human umbilical vein endothelial cells (HUVEC) stimulated by the supernatant was measured with MTT methods, untreated MSCs and pcDNA3.0 transfected MSCs were used as control groups.MAIN OUTCOME MEASURES: ① Result of restriction enzyme digestion and DNA sequencing of the recombinant plasmid pcDNA3.0-VEGF165;② the secretion of human VEGF165 proteins of the transfected MSCs analyzed by ABC-ELISA; ③ MTT method was used to detect the effects of MSCs culture supematant transfected with VEGF165 on HUVEC cells proliferation ability.RESULTS: ①Result of restriction enzyme digestion and DNA sequencing of the recombinant plasmid: The constructed plasmid was digested with Hind Ⅲ and XHol Ⅰ, and then two pieces fragments were isolated with agarose gel electrophoresis, which was accordance with expected results. And sequencing results showed that PeDNA3.0-VEGF165 eukaryotic expression vector was successfully constructed. ② ABC-ELISA method: Compared with the control group, concentration of human VEGF protein in the supernatant of the cultured cells increased significantly after the MSCs were transfected with pcDNA3.0-VEGF165 for 24, 48, 72 hours (P＜0.05).③ MTT method was used to detect the effects of MSCs culture supernatant transfected with VEGF165 on HUVEC cells proliferation ability. The results showed MSCs supematant transfected with VEGF165 (2%, 4%,8%, 16%, and 32%) had statistical significance in promoting HUVEC cells proliferation rate compared with the normal control (P＜0.05).CONCLUSION: Human VEGF gene can be successfully transfected into MSCs and expressed effectively.

Objective To further understand the clinical manifestations and improve clinical diagnosis of patients with leptomeningeal metastasizing high-grade glioma.Methods Sixteen patients with leptomeningeal metastasizing high-grade glioma (WHO classification:grade Ⅲ-Ⅳ) in Department of Radiotherapy,the First Hospital of Jilin University from July 2010 to September 2015 were respectively analyzed.The pathological types included anaplastic gliomas (1),anaplastic oligodenastrocytoma (1),glioblastoma (12),small-cell glioblastoma (1),gliosarcoma (1).We reviewed the relative clinical manifestations of the patients,and further compared them with 163 patients with systemic malignant solid tumors at corresponding period.Results The median time from initial diagnosis to the diagnosis of leptomeningeal metastasis was 13.0 months (range 2-19 months).Plain and enhanced magnetic resonance imaging was obtained in all patients.The main radiographic characteristics included ependymal enhancement (11),leptomeningeal enhancement (3),nodules of implantation metastasis in spinal canal (1),cranial nerve enhancement (2),and ventricular dilatation (1).Eight patients received cerebrospinal fluid examination.The diagnosis of leptomeningeal metastasis in 15/16 patients was determined by radiographic findings.Comparing with leptomeningeal metastasis from systemic malignant tumors at the corresponding period,the incidence of headache in patients with high-grade glioma was significantly lower (6/16 vs 81.6％ (133/163);x2 =16.3,P ＜ 0.01);and the incidence of cranial nerve paralysis was also significantly lower (4/16 vs 56.4％ (92/163);x2 =5.79,P =0.016 1).The incidence of nerve root symptoms was lower than that of systemic malignant tumors,though without statistically significant difference (2/16 vs 26.4％ (43/163);x2 =1.49,P=0.222).Nine patients respectively received chemotherapy,intrathecal chemotherapy or intrathecal chemotherapy combined with whole brain radiotherapy.The median survival tine was 4.5 months (range 0.7-13.3 months).Conclusions The imaging examination played an important role in the diagnosis of high-grade leptomeningeal metastasizing glioma.Comparing with the systemic malignant solid tumors,the leptomeningeal metastasizing high-grade glioma had its unique clinical characteristics.
