This work summarizes the research development and molecular mechanism of Ebp1, a member of the proliferation-associated 2G4 family, in tumor proliferation and invasion. This research serves as a basis and support for further research on the mechanism of tumor proliferation and invasion. The low expression of Ebp1 in various cancers promotes tumor proliferation and invasion. Ebp1 inhibits E2F1, cyclin D1, and cyclin E transcription by interacting with Rb, human histone deacetylase 2, and the transcriptional repressor Sin3A. This inhibition triggers cell cycle arrest and suppresses cell proliferation. Ebp1 also influences cancer invasion and migration. However, the underlying mechanisms remain unknown and require further exploration.

BACKGROUND: Sjogre's syndrome is a common disease of aged people,in which, dry mouth and throat have disturbed chawing, swallowing and speech and have seriously affected living quality of patients. OBJECTIVE: To probe into the improvement of oral function treated with Chinese medicine based on differentiation of symptoms. DESIGN: Retrospective analysis on cases was designed. SETTING: Department of Periodontal Disease, College of Stomatology,Fourth Military Medical University of Chinese PLA. PARTICIPANTS: Thirty-six cases of Sjogre's syndrome were selected from clinic of Department of Periodontal Disease of Stomatology College of Fourth Military Medical University of Chinese PLA from May 2000 to February 2004, with agreement and in the know of patients. Of those, 5cases were male, 31 cases were female, aged varied from 27 to 70 years,with duration of sickness in range from 0.5 to 10 years. METHODS: ① On basis of moistening, drying up heat, producing fluid and stopping thirst, the drugs for activating blood circulation, resolving stasis, clearing away heat and detoxification were supplemented. Formula:shashen (Radix Glehniae), maidong (Radix Ophiopogonis), shihu (Herba Dendrobii), yuzhu (Rhizoma Polygonati Odorati), huafen (Radix Trichosanthis), xuanshen (Radix Scrophulariae), shengdi (Radix Rehmanniae), chenpi (Pericarpium Cirri Reticulatae), danshen (Radix Salviae Miltiorrhizae), banzhilian (herba Scutellariae Barbatae), bahuasheshecao (Herba Hedyotis Dissusae), etc. ②Treatment of vitamins and transfer factor were associated.③ Artificial saliva in local was applied to prevent from secondary infection. ④ It was to test 99Tc m parotid function (After 99Tc m was injected intravenously on elbow, the parotid uptaking and concentrated 99Tc m curve were traced immediately. When radioactivity intensity was increased to maximum, the patients were required to chaw Vit. C tablet, 200 mg. In following, it was to trace the minimum of 99Tc m radioactivity on decreased curve. Normal imaging was illustrated clearly, the development after Vit. C stimulationwas declined swiftly. Time-radioactivity curve illustrated obvious uptaking and excreting segments. Positive results were unclear parotid development or the development after Vit. C stimulation was not declined obviously. Time-radioactivity curve was of horizontal type, low-horizontal type, parabola type or persistent rising type), erythrocyte sedimentation (ERS) (Normal value: 0-15 mm/h for male adult, 0-20 mm/h for female adult) and a part of immunology, such as rheumatoid factor, immunoglobulin (I gG normal value: 7.6-16.6 g/L), immune complex, etc. The effect was determined as increased saliva secretion and improved oral function. MAIN OUTCOME MEASURES: 99Tc m parotid function test, rheumatoid factor, ERS, IgG and immune complex were applied to determine the therapeutic effects of Chinese herbs. RESULTS:Thirty-six cases all entered result analysis. ① After treatment, the positive rate of rheumatoid factor was lower significantly compared with that before treatment [36.7%, 73.3%,(x2=6.796, P < 0.01)]. The levels of ERS, IgG and immune complex were all decreased significantly compared with those before treatment [(35.50±5.65) mm/h,(13.47±1.58) g/L,(8.30±1.24) mg/L;(55.20±8.85)mm/h,(23.57±2.37) g/L,(14.96±2.21) mg/L; (t=3.549-4.962,P < 0.01)]. The result of 99Tc m parotid function test and main determined indexes had been improved for all. ② After treatment, dry mouth, dry eye and general symptoms were all improved of various degrees and saliva secretion was increased. Total effective rate reached 80.7%. CONCLUSION: Treatment based on differentiation of symptoms is applied in Chinese medicine. On basis of moistening, drying up heat, producing fluid and stopping thirst, the drugs for activating blood circulation, resolving stasis, clearing away heat and detoxification are supplemented and effectively promote rehabilitation of oral function in Sjogre's syndrome,such as chawing, swallowing, speech, etc.

Objective To understand the levels of plasma endothelin (ET) and calcitonin gene-related peptide (CGRP) in cough variant asthma(CVA) patients, and to investigate their correlation and clinical implications. Methods Thirty CVA patients,30 typical bronchial asthma patients and 25 healthy controls were recruited. Three milliliter limosis venous blood were drawn from each patient to measure the levels of plasma ET and CGRP by radioimmanity. Results ①The levels of ET in the CVA group and typical bronchial asthma group were higher than that in healthy controls (P < 0.01). Their values were (103.58±28.66) ng/L, (129.37±27.28) ng/L and (72.63±21.52)ng/L, respectively. The levels of CGRP in the CVA group and typical bronchial asthma group were (7.62±2.56) ng/L and(6.63±2.09)ng/L The level of CGRP in the healthy controls group was (21.60±3.29) ng/L. The first two groups were lower than the latter(P < 0.01). However, there was no significant difference between the CVA group and typical bronchial asthma group(P >0.05). ②ET and CGRP were negatively correlated in both CVA group(r= -0.819,P<0.05) and typical bronchial asthma group(r= -0.738,P<0.05). Conclusions ET and CGRP were negatively correlated in both CVA group and typical bronchial asthma group, which means that ET and CGRP were a couple of antagonistic factors participated in the regulation of CVA, and may play an important role in the process of CVA.

AIM: To detect the protein expression of TIMP3 and RUNX3 in bone marrow mononuclear cells (BMMCs) from acute leukemia (AL) patients and to investigate the relationship between the methylation status of genes and their expressional levels. METHODS: Protein expression of TIMP3 and RUNX3 in 50 samples of BMMCs and 10 samples of peripheral blood mononuclear cells (PBMCs) from healthy volunteers was detected by Western blotting. The prognostic factors related to AL and data from methylation specific polymerase chain reaction were also analyzed. RESULTS: The expression level of RUNX3 with methylation was less than that without methylation in BMMCs from AL patients. The complete remission (CR) rate was related to RUNX3 expression and blasts in bone marrow (BM). BMMCs from patients with silencing of RUNX3 and higher blasts in BM had a lower CR rate. CONCLUSION: Absence of RUNX3 protein expression resulting from methylation of RUNX3 promoter probably plays a role in the pathogenesis of AL and is of value in prognosis. No relationship between methylation of TIMP3 promoter and the pathogenesis of AL is observed.
