Objective To investigate the effect of enteral nutrition (EN) on the T lymphocytes-mediated immune function in patients with acquired immune deficiency syndrome (AIDS). Methods Totally 79 AIDS patients were randomly divided into enteral nutrition ( EN ) group ( supported with EN daily in addition to conventional treatment; n = 46) and control group (underwent conventional treatment only; n = 33 ). T lymphocytes including CD3, CD4, and CD8 cells as well as blood biochemical parameters including alanine aminotransferase ( ALT), aspartate aminotransferase (AST), glucose ( Glu ), total protein (TP), albumin ( ALB ), blood urea nitrogen (BUN) , Cr, and prealbumin (PA) were determined immediately before management (T0) and on the 30th day(T1). Results ALT, AST, Glu, TP, ALB, BUN, Cr, and PA showed no significant differences between these two groups before management ( all P ＞ 0. 05 ). The levels of TP ( P = 0. 015), ALB ( P = 0. 007 ), and PA ( P =0. 022 ) were significantly higher in EN group than those in control group at T1. The cell counts of CD3, CD4, and CD8 were not significantly different at T0, while the cell count of CD4 was significantly higher in EN group than that in control group at T1 ( P ＜ 0. 05 ). Conclusion EN can improve the nutritional status and T lymphocytesmediated immune function in AIDS patients.

To identify metabotropic glutamate receptor 4 (mGluR4) modulators by Ca2+ influx assay, we developed the functional cell-based high throughput-screening (HTS) assay. The human mGluR4 cDNA was transfected into HEK-293 stably expressing promiscuous G-protein (Ga alpha15) cells. Recombinant stable mGluR4 cell line was selected under Zeocin and validated by Ca2+ influx assay. The assay was optimized on loading time of Fluo Calcium Indicator, Dimethyl sulfoxide (DMSO) tolerance and sodium hydroxide (NaOH) tolerance using agonist (L-Glutamic acid (L-Glu)) of mGluR4. The rank order of the agonist potency for the stable human mGluR4 cell line was L-(+)-2-Amino-4-phosphonobutyric acid (L-AP4) > L-Serine-O-phosphate (L-SOP) > L-Glu, and of the antagonist potency was (RS)-alpha-Methylserine-O-phosphate (MSOP) > (RS)-alpha-Methyl-4-phosphonophenylglycine (MPPG). Z' factor value of the cell line in 96- and 384-well plate format was 0.80 and 0.65. Our data indicate a successful development of functional human mGluR4 recombinant stable cell line that was suitable for high throughput screening to identify mGluR4 agonist/antagonist.

Objective To determine whether the CD133+ cancer stem cells lie in circumferential resection margin of rectal cancer,and to explore the relationship between CD133+ cancer stem cells and prognosis of rectal cancer.Methods The circumferential resection margin of rectal cancer was cut,one half of the tissue was stained HE for microscope observation.Both groups were labeled CD133 by immunohistochemistry.The tissues with positive circumferential resection margin were classified as experimental group,otherwise the control group.Another half was made into single cell suspension and used to detect CD133+ cancer stem cells by flow cytometry.The relapse of patients in the experimental group was following-up.Results Two cases were positive by immunohistochemistry in the experimental group (28 cases),showed that CD133+ cancer stem cells were in circumferential resection margin,but there was not marked difference compared with the control group (72 cases were all negative) (P =0.076).CD133+ cancer stem cells can be detected by flow cytometry,and the expression was higher in experimental group than that in the control group (5.19 ％ and 0.56 ％,Z =-7.739,P ＜ 0.01).In experimental group,the expression of CD133+ cancer stem cells in circumferential resection margin of relapse patients was significantly higher than that in patients without relapse,the difference was statistically significant [(6.57±1.72) ％ and (4.77±1.33) ％,t =3.038,P ＜ 0.05].Spearman rank correlation analysis showed that the proportion of CD133+ cancer stem cells in the experimental group was positively correlated with relapse (rs =0.473,P ＜ 0.05).Conclusion There are CD133 + cancer stem cells within circumferential resection margin of rectal cancer,and the expression of CD133+ cancer stem cells in experimental group is correlated with the postoperative recurrence.

Objective To study the pathogenic bacteria distribution and drug resistance characteristics in HIV/AIDS patients with lower respiratory tract infection in Yunnan province, so as to guide the clinical medication. Methods We collected 278 cases of hospitalized patients with sputum,alveolar lavage specimen smear, culture, positive specimens from HIV/AIDS patients with lower respiratory infection in The Third People’s Hospital of Kunming from January 2008 to December 2012. Then we retrospectively analyzed the collected data. Results From 278 cases of sputum and alveolar lavage fluid specimens,we isolated a total of 127 strains of bacteria (45.7%), 53 strains of fungus (19.1%),50 strains of white candida,3 strains of aspergillus,49 strains of mycobacterium, 44 strains of mycobacterium tuberculosis,and the rest of atypical mycobacteria. Gram negative bacilli accounted for 64.6%,followed by pneumonia klebsiella bacteria, pseudomonas aeruginosa,e. coli,acinetobacter,sewer,e. coli, gram-positive bacteria accounted for 15.4%. Fungi accounted for 19.1%, and candida albicans was the common fungus. Mycobacterium tuberculosis accounted for 17.6%. Gram-negative bacilli were sensitive to imipenem, ptilinum ketone/sulbactam and amikacin,gram-positive bacilli were sensitive to vancomycin, nitrofurantoin and imipenem. Conclusions The major pathogenic bacteria are gram-negative bacilli in HIV/AIDS patients with lower respiratory tract infection in Yunnan province,but fungal infection ratio is increasing year by year, and conditional pathogenic bacteria are the major pathogen,which have antimicrobial resistance with different degree,TB infection rate is high and multi-drug resistant TB appears. Antimicrobial agents should be rationally used to delay the appearance of pathogen resistance.

Objective:To detect the effect of EphrinA1-Fc on the phosphorylation of EphA2 and extracellular signal-regulated ki-nase (ERK) in 786-O renal carcinoma cells (RCCs). Methods:The soluble ligand EphrinA1-Fc was used to inhibit the 786-O RCCs in vitro. Western blot analysis was used to examine the phosphorylation of EphA2 and ERK1/2 in the 786-O RCCs at different time points. Results:After the intervention with EphrinA1-Fc for 5, 10, 30, and 60 min, the expression of p-EphA2 increased (F=9.392, P=0.025) as well as that of p-ERK (F=4.428, P=0.041). No p-EphA2 and p-ERK expression was observed in the pre-intervention group. Conclusion:One of the possible mechanisms of the inhibitory effect of EphrinA1-Fc on tumor metastasis and recurrence involves the phosphorylation of EphA2 by EphrinA1-Fc, leading to the degradation of EphA2.

Objective To investigate the relationship between polymorphisms in mitochondrial displacement-loop (mtDNA D-loop) and renal cell carcinoma. Methods Fifty-nine patients with clear cell renal cell cancer (renal cancer group) and 68 healthy control (control group) were selected in this study. The mtDNA D-loop region was amplified and se-quenced using polymerase chain reaction (PCR). Data were compared and analysed with the Revised Cambridge Reference Sequence (rCRS) in library of mitochondria. The difference in frequency analyses of mtDNA D-loop region was compared be-tween two groups. Results A total of 143 single nucleotide polymorphisms (SNP) of mitochondria D-Loop region were de-tected in renal cancer group and control group. Compared with control group, there were significantly higher frequencies of 262T and 16293G alleles in mitochondria D-loop region, and significantly lower frequencies of 16298C and 16319A alleles, in renal cancer group (P<0.05). Conclusion The analysis of genetic polymorphisms in the D-loop can be used as predic-tors of renal cell carcinoma and contribute to the early detection in patients of renal cell carcinoma.

Objective To explore the effects of the different concentrations of magnesium ions on vascular smooth muscle cell (VSMC) calcification in rats. Methods VSMCs were obtained from rat aortic, and were identified by immunocy-tochemistry. VSMCs were then randomly divided into control group, high phosphorus group and magnesium intervention group. VSMCs were cultured with 10%fetal bovine serum in control group. VSMCs were cultured with high phosphorus in high phosphorus group. VSMCs were cultured with different concentrations of magnesium chloride based on the high phos-phorus medium in magnesium intervention group (final concentrations of magnesium ions were 1, 2 and 3 mmol/L). The calci-um content and alkaline phosphatase(ALP)activity were measured after the stimulation for 7 days. The expression of Cbfα1 mRNA was detected by RT-PCR. Results Compared with control group, calcium deposits were found significantly higher in high phosphorus group and magnesium intervention group. The calcified nodules gradually reduced with the increased magnesium ion concentration in the intervention group. The calcium contents were significantly lower in the intervention groups (2 and 3 mmol/L) compared with those of high phosphorus group (P<0.05), but no difference was found between 1 mmol/L magnesium intervention group and high phosphorus group. There were no significant differences in the ALP activity and Cbfα1 mRNA expression between intervention groups (2 and 3 mmol/L) and control group (P<0.05). The ALP activity and the expression of Cbfα1 mRNA were gradually decreased with the increased magnesium ion concentration in the inter-vention group, and which were lower than those of high phosphorus group (P<0.05). Conclusion Magnesium can reduce calcification and osteoblastic transdifferentiation, which may be achieved by reducing the expression of Cbfα1 in VSMCs.

Objective To explore the effect and mechanism of magnesium on calcification induced by hyperphosphate.Methods Vascular smooth muscle cells (VSMCs) were primarily cultured in vitro and induced calcification by β-glycerophosphate (β-GP).VSMCs were randomly divided into control group,high phosphorus group (10 mmol/L β-GP),magnesium intervèntion group(10 mmol/L β-GP + 3 mmol/L MgSO4) and 2-aminoethoxy-diphenylborate (2-APB,an inhibitor of magnesium transporter) intervention group(10 mmol/L β-GP+3 mmol/L MgSO4+ 10-4 mol/L 2-APB).Calcium deposition and alkaline phosphatase (ALP) activity were measured by alizarin red staining,quantification of calcium and euzyme linked immunosorbent assay.RT-PCR and Western blotting were used to observe the expression of core binding factor α-1 (Cbfα-1) mRNA and protein,respectively.In vivo,male Sprague-Dawley rats (n=24) were randomly divided into control group (methylcellulose+high phosphorous diet),vascular calcification group (adenine suspension + high phosphorous diet),high magnesium intervention group(adenine suspension+high phosphorous and magnesium diet).The aortic pulse wave velocity (PWV) was measured,and vascular calcification was determined by von Kossa stain and quantification of calcium.Cbfα-1 in aortic was measured by immunohistochemistry.Results In vitro,compared with high phosphorus group,calcification,ALP activity (P ＜ 0.05) and Cbfα-1expression in VSMCs were significantly decreased in magnesium intervention group after incubation for 14 days,but the addition of 2-APB might inhibit the protective effect of magnesium on VSMCs.Dynamic observation of Cbfα-1 showed that magnesium significantly inhibited the expression of Cbfα-1 (P ＜ 0.05) on the third day and the inhibitory role was obviously increased in a time-dependent manner.Consistent with the findings in vitro,the aortic PWV,calcification were all significantly reduced (P ＜ 0.05) in high magnesium intervention group with high serum magnesium level,when compared with vascular calcification group.Immunohistochemistry showed that hypermagnesemia downregulated obviously the expression of Cbfα-1 induced by hyperphosphatemia(P ＜ 0.05).Conclusion Magnesium protects against vascular calcification by inhibiting osteogenic differentiation of VSMCs.
