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 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 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 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.

Objective To explore the effect of vitamin K2 on β-glycerophosphate(β-GP)-induced rat vascular smooth muscle cells (VSMCs) calcification and and the mechanism.Methods VSMCs were obtained from rat aortic,and identified by immunocytochemistry,then randomly divided into control group,high phosphorus group,vitamin K2 group (the group was settled three subgroups according to the concentration of vitamin K2 based on the high phosphorus medium,namely 10 μmol/L,25 μmol/L,50 μmol/L) and noggin (bone morphogenetic protein pathway inhibitor) group.Calcification was visualized by Alizarin red staining,calcium load in cells was quantified by o-cresolphthalein complexone method and alkaline phosphatase (ALP) activity was measured after stimulating 14 days,gene expressions of bone morphogenetic protein-2 (BMP-2),SMAD1,SMAD7 and Runx2 mRNA were detected by RT-PCR,Runx2 protein levels was detected by Western blotting after stimulating 3 days.Results Compared with the cells in control group,high phosphorus induced cell calcification,increased ALP activity,up-regulated the expression of BMP-2,SMAD1,Runx2 mRNA (P ＜ 0.05) and down-regulated the expression of SMAD7 (P ＜ 0.01),while compared with high phosphorus group,the calcium deposition,ALP activity and the expression of BMP-2,SMAD1,Runx2 mRNA were remarkably reduced in a dose-dependent manner by treatment with vitamin K2 (P ＜ 0.05) and the expression of SMAD7 was increased (P ＜ 0.01).Compared with high phosphorus group,SMAD1 and Runx2 expression in noggin group were remarkably reduced(P ＜ 0.01).Conclusion Vitamin K2 inhibits β-glycerophosphate-induced VSMCs calcification which correlates with the suppression of the expression of osteoblast markers through the down-regulation of bone morphogenetic protein pathway.

Objective To explore the correlation between anaplastic lymphoma kinase (ALK) fusion gene detected by immunohistochemistry (IHC) and reverse transcription-polymerase chain reaction (RT-PCR) in non-small cell lung cancer. Methods The ALK fusion protein/gene in 71 patients of NSCLC which was detected both by IHC (1A4/1H7) and RT-PCR were retrospective studies, and the 2 methods were compared. Results Among the 71 NSCLC patients, the ALK fusion protein positive was in 21 cases and negative was in 50 cases by IHC detected, while the ALK fusion gene positive was in 12 cases and negative was in 59 cases by RT-PCR. The ALK fusion genes detected by RT-PCR were all negative when IHC negative and IHC 1+. All patients with IHC 2+ and IHC 3+ were confirmed ALK fusion genes positive with RT-PCR. The positive rate of ALK fusion protein detected by IHC in large surgical specimens was 28.95%(11/38), and the positive rate of ALK fusion protein detected by IHC in small biopsy specimen was 30.30%(10/33). The positive rate of ALK fusion gene detected by RT-PCR in large surgical specimens was 18.42%(7/38), and the positive rate of ALK fusion gene detected by RT-PCR in small biopsy specimen was 15.15% (5/33). Conclusions Although the ALK fusion protein detected by IHC may have certain false positive, IHC is highly consistent with RT-PCR in IHC 2+and IHC 3+ cases. The combination of IHC and RT-PCR can be used to ALK fusion gene positive NSCLC screening and diagnosis. The small biopsy specimen is also good material for ALK detection, when the surgical specimen can not be got from patients.

OBJECTIVE:To evaluate the rationality and validity of chemical medicine tablet production equipment cleaning pro-cedure. METHODS:Among several chemical medicines prepared by similar production technology as Metoprolol succinate sus-tained-release tablets,Captopril tablets,Isosorbide mononitrate tablet and Metformin hydrochloride tablet,Metoprolol succinate sus-tained-release tablets had strongest toxicity and were included in validation test. The production equipment was cleaned and disinfect-ed according to cleaning procedure. The point which was most difficult to clean could be wiped and sampled by using the cotton swab method. The detection limit and the limit of quantitation of the residue limits were verified as well as the recovery rate of wip-ing,in order to evaluate whether the results meet the requirements. RESULTS:The cotton swab method is adopted to wipe sample and detect the point which is most difficult to clean. The visible foreign body has not been found in each sampling point. The amount of residual drug is <29.75 μg/cotton bud,and microbial limits are <50 CFU/cotton bud,indicating test items are in line with the standard. CONCLUSIONS:The cleaning method can effectively clean the production equipment,and can effectively pre-vent product contamination and cross contamination to ensure the quality,efficacy and safety of the next batch of products.
