Objective To investigate the inhibitory effect of ester catechin monomers-EGCG, GCG on the growth of human colon carcinoma cell line SW480 and its potential mechanism. Methods MTT assay, soft-agar colony formation test, Hoechst 33258 stain and flow cytometry analysis were used to determine the inhibitory effect of theasinesin(TS), and its monomers-EGCG, GCG on SW480 growth. Results EGCG, GCG and TS significantly inhibited the growth of human colon carcinoma cell line SW480 in dose-dependent manner, and their half inhibitory concentration (IC 50 ) was 108.88, 183.21, and 83.36?g?ml -1 , respectively. 24 hours after treatment with IC 50 of EGCG, GCG and TS, the colony formation rate of SW480 cells in the experimental group was obviously lower than that in the control group. Hoechst 33258 staining showed typical apoptotic features such as cell shrinkage, nuclear condensation and cell splinter in the experimental group. A subdiploid peak before G 0/G 1 phase in the experimental group was observed by flow cytometry. Conclusion In accord with TS, EGCG and GCG could inhibit the growth of colon carcinoma cell line SW480 cells, the mechanism of which may be related to inducing cell apoptosis.

Objective To investigate the levels of creatine kinase (CK-MB), brain natriuretic peptide (BNP), and neu-ropeptide Y (NPY) in severe pneumonia pediatric patients combined with heart failure (HF). Methods Pneumonia pediatric patients admitted from December 2010 to December 2014 had been enrolled and divided into pneumonia group (P) (n=32), se-vere pneumonia group (SP) (n=20) and severe pneumonia combined HF group (HF) (n=36). Twenty healthy children served as control group (C). Serum level of CK-MB was detected by enzyme rate method and were measured by ELISA. BNP and NPY were measured again during the recovery period in 18 cases in HF group. Results The serum levels of CK-MB, BNP and NPY were signiifcantly different among the four groups, (F=25.19~277.94, P<0.01). The serum levels of CK-MB, BNP and NPY were signiifcantly higher in HF group than in SP, P and C group (P<0.05). The serum level of CK-MB was signiifcantly higher in SP group than that in P and C group (P<0.05) and there was no difference between P and C group (P>0.05). The serum levels of BNP and NPY were not statistically signiifcant between SP and P and C group (all P>0.05). In HF group, the serum levels of CK-MB, BNP, and NPY were signiifcantly decreased in 18 cases after treatment. The serum level of BNP was positively correlat-ed with CK-MB and NPY (r=0.681, 0.525, all P<0.01) and the NPY and CK-MB levels were also positively correlated (r=0.545, P<0.01). Conclusions The Detection of the serum levels of CK-MB, BNP and NPY can help diagnose severe pneumonia com-bined with HF. The BNP maybe the most sensitive indicator.

In recent years , the emergence and progress of cancer genomics and targeted therapies have remarkably expanded the application fields of protein-protein interaction in cancer research .Fluorescence resonance energy transfer ( FRET ) is a kind of nonradiation energy transfer technique , which can timing , quantitative , positioning , and dynamically monitor the interaction between protein and protein in living cells .With the discovery of novel fluorescent proteins and the development of FRET -based biosensors , FRET has became an important method for visualizing spatial and temporal dynamics of interactions among biological macromolecules in native environments .This review summarises the recent studies and technological advances that have enhanced the use of FRET tech -nology in cancer basic research , early diagnosis , prognosis evaluation , drug development and other areas .

Objective To investigate the requirement of health education for patients with spinal tuberculosis,making clinical education form,and determine the evaluation system.Methods 134 cases of spinal tuberculosis patients were surveyed with self-designed questionnaires.The questionnaire included 5 aspects,using the Likert 4 scoring method.Delphi method was applied in 16 experts.Results The health demand of patients showed high positive correlation in domains of cognition and operation.There was a moderate positive correlation between affective domain and cognition,operation domain.Two rounds of expert consultation showed that the expert opinion coordination coefficient was 100％,the average of authority was above 0.8,the expert opinion coordination coefficients of all the indexes were between 0.2～0.6.Conclusions The health education form for spinal tuberculosis patients can help to understand the needs of patients,it is pertinent and get the recognition of experts.

AIM: To investigate the molecular mechanism of Epstein-Barr virus encoded latent membrane protein 1 regulated cellular proliferation in nasopharyngeal epithelial cells. METHODS: The nasopharyngeal epithelial cells NP69 were infected with RV-pLNSX (the empty vector) and RV-LMP1 retroviruses, respectively. Therefore, the NP69-pLNSX and NP69-LMP1 cell lines were established. Sequentially, cellular proliferation of NP69-pLNSX and NP69-LMP1 cells was compared to draw the cellular growth curve. The experiments of plate clone formation and forming of soft agar colony were conducted. Meanwhile, the differential expression of proteins were identified between NP69-pLNSX and NP69-LMP1 cell lines by proteomic methods, and the expression levels of partial identified proteins were verified. RESULTS: (1) LMP1 was able to accelerate cellular proliferation of nasopharyngeal epithelial cell NP69 (n=3, P<0.05). (2) Twenty two proteins (9 up-and 13 down-regulated) of LMP1 mediated regulation were identified from infected NP69 cell lines, and the differential expression of partial identified proteins was confirmed by Western blotting and fluorescent real-time quantitative RT-PCR. CONCLUSION: LMP1 probably mediates the regulation of vimentin protein and keratin 19 protein expression to promote cellular proliferation in NP69 cells.

Adolescent idiopathic scoliosis (AIS) is a three-dimensional deformity of the spine,which not only affects spinal anatomy,mobility and trunk symmetry,but also leads to the changes of human locomotion through pelvic.During the past 30 years,though great progress has been made in the treatment of AIS,the pathogeny of AIS is still uncertain.Most scholars believe that many factors contribute to the pathogeny of AIS,however,some studies have shown that poor posture during walking and poor manage of balance could lead to the progress of scoliosis.Gait is a behaviour characteristic during walking,and normal gait is the result of nervous system,musculoskeletal system,proprioception and vision.Any disease of the system above may cause abnormal gait.Gait analysis can spot the key links and impact factors of abnormal gait by observing and measuring the testers' walking,reflect the abnormal gait objectively and quantitatively,and provide reference opinions for the recovery and treatment of patients.At present,gait analysis has been mostly applied in hemiplegia,cerebral palsy and knee osteoarthritis.In recent years,gait analysis has been increasingly used in AIS patients.There have been many researches about the kinematics and kinetics of gait analysis in adolsecent idiopathic scoliosis abroad and some positive results have been reported..But in China,it's still in the initial stage.We reviewed the published papers about gait analysis in AIS patients,and summarized the kinematics,kinetics and different means of intervention on gait in AIS patients.We hope it will provide references for our researches.
