OBJECTIVETo explore the effect of Bushen Huoxue Compound (BHC) on lactate dehydrogenase (LDH) leakage, expressions of vascular endothelial growth factor (VEGF) and VEGF mRNA in retinal Muller cells under high glucose condition or advanced glycosylation end products (AGEs) condition by using serum pharmacological method.
METHODSThe retinal Müller cells of 5-7 days post-natal Sprague Dawley (SD) rats were cultured with modified enzyme-digestion method. Purified retinal Muller cells were cultured in normal conditions, high glucose condition (50 mmol/L) or AGEs (50 mg/L and 100 mg/L) conditions, and BHC-containing serum was added to culture medium. The LDH leakage and VEGF expressions were measured by enzyme-linked immunosorbent assay (ELISA). In addition, the relative expression of VEGF mRNA was tested by reverse transcription polymerase chain reaction (RT-PCR).
RESULTSCompared with the normal control group, expressions of VEGF and VEGF mRNA were significantly increased in the high glucose group, the low dose AGEs group and the high dose AGEs group (all P < 0.01). The LDH leakage was obviously increased in the high dose AGEs group, when compared with the normal control group and the high glucose group (P < 0.01). The LDH leakage, expressions of VEGF and VEGF mRNA were obviously decreased by BHC-containing serum both in high glucose and AGEs conditions (P < 0.05, P < 0.01). BHC-containing serum had no significant effect on the LDH leakage and expressions of VEGF and VEGF mRNA in normal conditions (P > 0.05).
CONCLUSIONSAGEs intervention could obviously lower the stability of Müller cell membrane. Up-regulated expressions of VEGF and VEGF mRNA in cultured Müller cells could be induced by AGEs or high glucose. BHC-containing serum could stabilize the stability of Müller cell membrane, inhibit the transcription of VEGF mRNA and decrease the protein expression of VEGF, which might be one of important mechanisms for preventing and treating diabetic retinopathy.

The objective of this study was to investigate the relationship between the expressions of breast cancer resistance protein (BCRP) gene and drug resistance as well as prognosis in adult patients with acute lymphocytic leukemia (ALL). Semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR) was used to detect the expression of BCRP gene in 97 adult patients with acute lymphocytic leukemia (ALL) and 30 normal subjects. Beta(2) microglobulin (beta(2)-MG) was used as an internal reference. BCRP/beta(2)-MG ratio >or= 0.48 was defined as BCRP positive. The results showed that the positive ratio of BCRP gene expression in untreated group was 28.7%, in contrast that in refractory and relapsed patients was 51.2%. The first complete remission rates in patients with negative and positive expression were 71.7% and 29.7% respectively. In ALL subtypes BCRP gene expression of L3 type was distinctly higher than that of L(1), L(2) types. In immune types the BCRP gene expression of B-ALL was higher than that of T cell type, especially in mature B cell type with obviously statistical significance (p<0.01). It is concluded that the high expression of BCRP gene may induce clinical drug resistance, and may be an unfavorable factor for prognosis in adult patients with acute lymphocytic leukemia.

OBJECTIVETo isolate CD133(+)/CD44(+)/ESA(+) subsets cells from SW480 colon cancer cells, and to observe the tumor formation.
METHODCD133(+)/CD44(+)/ESA(+) subsets cells, CD133(-)/CD44(+)/ESA(+) subsets cells and CD133(-)/CD44(-)/ESA(-) subsets cell were sorted by flow cytometry from SW480 colon cancer cells, then three subsets were separately inoculated in five NOD/SCID mice and the growth rates were calculated.
RESULTThe proportion of CD133(-)/CD44(-)/ESA(-), CD133(-)/CD44(+)/ESA(+) and CD133(+)/CD44(+)/ESA(+) subsets cells in SW480 cells were (86.38±10.23)%,(1.26±0.28)% and(0.38±0.07)%. After inoculation, tumor nodules could be formed three days later in CD133(+)/CD44(+)/ESA(+) group, and they could be formed 9 days later in CD133(-)/CD44(+)/ESA(+) group, while they could be formed 15 days later in CD133(-)/CD44(-)/ESA(-) group. Eighteen days later, tumor sizes in three groups were(13.82±5.04) mm(3), (9.25±4.57) mm(3) and (4.76±3.92) mm(3) respectively, and the differences were statistically significant(P<0.05).
CONCLUSIONESA(+)-CD44(+) is one of the surface markers for colonic cancer stem cells, and CD133(+)-CD44(+)-ESA(+) cells are SW480-like cancer stem cells.

A rapid detection of foot-and-mouth disease virus (FMDV) was established by using reverse transcription loop-mediated isothermal amplification (RT-LAMP) method, meanwhile its specificity and sensitivity were assessed. The results showed that the FMDV RNA could be amplified by incubation at 65degrees C for only 1h using six primers designed based on FMDV polyprotein gene and the amplification products could be detected easily by naked-eye. There is no cross reaction with other virus such as SVDV, SFV and PPV by detecting their RNA samples. The detection limit of this method was found to be 10(-5) dilution of RNA sample which was 100-fold higher than that of PCR and 10-fold higher than real-time PCR.

Chronic myeloid leukemia (CML) is characterized by the accumulation of active BCR-ABL protein.Imatinib is the first-line treatment of CML;however,many patients are resistant to this drug.In this study,we aimed to compare the differences in expression patterns and functions of time-series genes in imatinib-resistant CML cells under different drug treatments.GSE24946 was downloaded from the GEO database,which included 17 samples of K562-r cells with (n=12) or without drug administration (n=5).Three drug treatment groups were considered for this study:arsenic trioxide (ATO),AMN107,and ATO+AMN107.Each group had one sample at each time point (3,12,24,and 48 h).Time-series genes with a ratio of standard deviation/average (coefficient of variation) >0.15 were screened,and their expression patterns were revealed based on Short Time-series Expression Miner (STEM).Then,the functional enrichment analysis of time-series genes in each group was performed using DAVID,and the genes enriched in the top ten functional categories were extracted to detect their expression patterns.Different time-series genes were identified in the three groups,and most of them were enriched in the ribosome and oxidative phosphorylation pathways.Time-series genes in the three treatment groups had different expression patterns and functions.Time-series genes in the ATO group (e.g.CCNA2 and DAB2)were significantly associated with cell adhesion,those in the AMN107 group were related to cellular carbohydrate metabolic process,while those in the ATO+AMN107 group (e.g.AP2M1) were significantly related to cell proliferation and antigen processing.In imatinib-resistant CML cells,ATO could influence genes related to cell adhesion,AMN107 might affect genes involved in cellular carbohydrate metabolism,and the combination therapy might regulate genes involved in cell proliferation.

Objective To study and analyze of clinical effect of Kangfuxin liquid combined with traditional Chinese medicine enema in the treatment of radiation enteritis. Methods 120 cases of radiation enteritis caused by radiotherapy in the affiliated hospital of Southwest medical University from February 2015 to August 2016 were selected as the research objects. They were randomly divided into the control group and the experimental group, 60 cases for each group. The control group was given 100mL saline and 10mg dexamethasone enema treatment. The patients in the experimental group were given Kangfuxin liquid combined with Traditional Chinese Medicine enema treatment, two groups of patients were treated for 4 weeks. The therapeutic effects of the two groups were compared and analyzed. Results In the experimental group, 6 patients were cured, 34 cases were improved, 20 cases were cured. In the control group, 21 patients were cured, 23 cases were improved, 16 cases were cured. The effective rate of treatment in the experimental group was 90.0%, which was significantly higher than that in the control group, and the effective rate was 65.0%, with statistical difference (P<0.05). There were no obvious adverse reactions in the experimental group and the control group. The average hospital stay in the control group was (30.98±2.10) d, significantly longer than the experimental group, the average length of stay (23.89±2.31) d, with statistical difference (P<0.05). Conclusion Kangfuxin liquid combined with Traditional Chinese Medicine enema in the treatment of the has good clinical effect in treating radiation enteritis, and high effective rate of treatment of radiation enteritis with high safety.
