Objective To explore the effect of recombinant pEGFP-N3-APC vectors carrying various APC functional domains on the expression of β-catenin in human colorectal cancer cells HT-29.Methods The recombinant plasmids were transfected into HT-29 cells mediated by lipofectamine~(TM) 2000, and detected by green fluorescence and RT-PCR. Western blot was applied to detect β-catenin expression level in HT-29 cells after transfection, and gray scales of electrophoresis strips were analyzed by SPSS 13.0.Results Green fluorescence and RT-PCR made clear that all 5 recombinant plasmids were successfully expressed in HT-29 cells. Western blot showed that β-catenin expression level in HT-29 cells was not affected after being transfected with pEGFP-N3-APC1, pEGFP-N3-APC2 and pEGFP-N3-APC3, and was distinctly affected after being transfected with pEGFP-N3-APC4 and pEGFP-N3-APC5, especially the later one. Conclusion The selected APC5 gene fragment with 15-amino acid repeats and SAMP repeats, which is relatively short, can degrade β-catenin level in HT-29 cells and may be applied in the gene therapy.

AIM:To investigate COX-2 and iNOS protein contents and their interaction in vascular endothelium injury of rats with deficiency of vital energy or qi stagnation,and the prevetion and treatment of Tongxinluo.METHODS:The model of vascular endothelium injury of rats with deficiency of vital energy or qi stagnation was established by using high L-Methionine,with load-carrying swimming or being fastened respectively.Western blotting was used to analyze protein contents of COX-2 and iNOS,co-immunoprecipitation and laser confocal microscopy were used to analyze the interaction between COX-2 and iNOS.Optical microscope and electronic microscope were used to evaluate pathological changes in vascular endothelium.RESULTS:The protein contents of COX-2 and iNOS,and their interaction increased significantly in deficiency of vital energy group and qi stagnation group,in accord with injury of vascular endothelium.Compared with deficiency of vital energy group and qi stagnation group respectively,their protein contents decreased and their interaction was weakened in Tongxinluo groups.CONCLUSION:When protein contents of COX-2 and iNOS increase and their interaction enhance after vascular endothelium injury of rats with deficiency of vital energy or qi stagnation,initiate exacerbations,Tongxinluo could attenuate the alterations and protect vascular endothelium from injury.

The amount of acupuncture treatment refers to the sum of acupuncture effects during the treatment. From the factors that constitutes the amount of acupuncture treatment, including the numbers of needling, the size of acupuncture instruments, the depth of acupuncture, the manipulation, the retained time of needle, etc., and combined with teaching and clinical experience, it is believed that the amount of acupuncture treatment is closely related with clinical efficacy, besides, moderate amount of acupuncture treatment is a key factor to improve acupuncture efficacy and guarantee the safety of acupuncture. The basic principles of regular treatment amount are arrival of qi and being moderate, indicating the retained time of needle, treatment frequency and course should be based on individual condition, time, location and disease.

BACKGROUND:Pelvic and acetabular fractures in elderly are frequently observed in the clinic, and the incidence gradual y increased. Moreover, it is difficult to conduct reduction and fixation due to their physical status and osteoporosis to different degrees. Locking plate is ideal fixation material in surgical treatment of acetabular fractures in elderly due to the special functions and good molding of screw and locking plate.
OBJECTIVE:To analyze the advantages and disadvantages of locking reconstruction plate used in the acetabular fracture for the aged patients and to improve the clinical effect of acetabular fractures in elderly.
METHODS:From January 2010 to February 2013, 21 aged patients with acetabular fracture were treated by open reduction and internal fixation with locking reconstruction plates made of titanium and 00Cr 18 Ni 14 Mo 3 stainless steel in the Department of Orthopedics Affiliated Hospital of Jining Medical University.
RESULTS AND CONCLUSION:Of 21 patients, 20 cases were fol owed up for 12-18 months (mean 14 months), but one dropped out. Al the fractures were healed within 4-6 months and no failure cases. According to Matta evaluation criteria, the satisfactory rate was 90%. According to the D’Aubigne scoring system, the excellent and good rate was 95%. These data indicated that locking reconstruction titanium plate is reliable, has low failure rate and satisfactory clinical effects for acetabular fracture in aged patients, and is ideal fixation material in treatment of acetabular fractures in elderly.

Objective To investigate the expressions of CDX2 and β-catenin in acute lymphoblastic leukemia (ALL) and their correlation. Methods Real-time PCR was used to determine the expressions of CDX2 and β-catenin mRNA in 43 de novo ALL and 30 non-malignant patients (used as control). Results The positivity rate of CDX2 mRNA expression in ALL group was 93%, but CDX2 mRNA expression couldn′t be detected in the control group (P<0.01). The mRNA expression of β-catenin could be detected in patients in both two groups, butβ-catenin mRNA expression in the ALL group was significantly higher than in the control group (P < 0.01). And mRNA expressions of CDX2 andβ-catenin were significantly correlated with WBC counts and LDH level (P<0.01). When the ALL patients acquired complete remission (CR), the mRNA expressions of CDX2 and β-catenin were significantly decreased compared with their newly diagnosed status , while disease-relapsed the mRNA expressions of CDX2 andβ-catenin were increased again. There was significantly positive correlation between CDX2 and β-catenin mRNA expressions (r = 0.835, P = 0.000). Conclusion Up-regulation of CDX2 and activation of Wnt/β-catenin pathway coexist in the ALL patients and the mRNA expressions of CDX2 and β-catenin are positively correlated.

AIM: To observe the different changes of neuroendocrine systems between the state of sport fatigue and poverty of movement. METHODS: 60 male Wistar rats were randomly divided into three groups: normal control group, sport fatigue model group and poverty of movement model group (20 rats in each group). The sport fatigue model was established by the method of combining basal diet and loaded swimming during 2 weeks, whereas the method of restricted activities was used to establish the poverty of movement model with total experimental time of 10 weeks. By the end of experiment, the climbing pole time was determined. The contents of hypothalamus thyrotropin releasing hormone (TRH), and serum norepinephrine (NE) and epinephrine (E) in rats with different treatments were determined by ELISA. In addition, the changes of hypothalamus corticotropin release hormone (CRH), pituitary adrenocorticotropic hormone (ACTH) and thyroid stimulating hormone (TSH), and serum corticosterone (CORT), triiodothyronine (T_3), tetraiodothyronine (T_4) were determined by radioimmunoassay to evaluate the functions of adrenergic nerve-adrenomedullin system, hypothalamo-pituitary-adrenal (HPA) axis and hypothalamo-pituitary-thyroid (HPT) axis. RESULTS: Compared to control group, the climbing pole time of the animals was obviously decreased in two model group. The adrenergic nerve-adrenomedullin system and HPA axis were inhibited in sport fatigue model rats, but HPT axis was unchanged. Interestingly, the HPA axis was hyperfunctional and HPT axis was inhibited in poverty of movement model rats. However, no change in the adrenergic nerve-adrenomedullin system was observed. CONCLUSION: Sport fatigue and poverty of movement all affect neuroendocrine system and lead to the adjustment mechanism imbalance, but the target and tendency are different.

OBJECTIVE:To systematically review the effect of ticagrelor versus prasugrel on platelet reactivity,and provide evi-dence-based reference for clinical treatment. METHODS:Retrieved from PubMed,CJFD and Wanfang Database,randomized con-trolled trials(RCT)about the effect of ticagrelor versus prasugrel on platelet reactivity were collected. Meta-analysis was performed by using Rev Man software after data extract and quality evaluation by Cochrane 5.1.0. RESULTS:Totally 17 RCTs were enrolled,involv-ing 2 757 patients. Results of Meta-analysis showed,regardless of Verity Now(VN)detection method [MD=15.43,95%CI(-0.39, 31.25),P=0.06] or vasodilator stimulus phosphoprotein(VASP)detection method [MD=-3.04,95%CI(-8.98,2.90),P=0.32], ticagrelor and prasugrel had the same effects on platelet reactivity under loading dose,the differences were not statistically significant;regardless of VN detection method [MD=-48.94,95%CI(-58.04,-39.84),P<0.001] or VASP detection method [MD=-14.32, 95%CI(-20.45,-8.20),P<0.001],the effects of ticagrelor were better than prasugrel on platelet reactivity under maintenance dose,the differences were statistically significant. CONCLUSIONS:At the loading dose,there was no difference between ticagrelor and prasugrel,but ticagrelor has more benefits than prasugrel under maintenance dose.
