Objective To investigate the feasibility of tissue-specific gene therapy for bladder cancer using human UroplakinⅡ(UPⅡ) promoter. Methods The recombinant adenoviruses,Ad-hUPⅡ-TNF carrying tumor necrosis factor (TNF-?) under control of the hUPⅡ,were generated.ELISA showed the production and secretion of TNF by bladder cancer cells infected with Ad-hUPⅡ-TNF.The level of TNF in urine was identified with ELISA. Results ELISA showed that production and secretion of TNF by bladder cancer cells infected with Ad-hUPⅡ-TNF was distinctly higher than by non-urothelium cells infected with Ad-hUPⅡ-TNF and MTT showed that proliferation of bladder cancer cells was obviously inhibited.Conditioned medium from bladder cancer cells apparently inhibited cells of L929 proliferation,compared with conditioned medium from non-bladder cells by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay.Intravesical inoculation of Ad-hUPⅡ-TNF also caused decreased tumor growth in orthotopic human bladder cancer model.The sustained high level of TNF in urine could be identified with ELISA. Conclusions TNF driven by hUPⅡ promoter has effective active in the inhibition of bladder cancer growth both in vivo and in vitro.These will undoubtedly yield a new approach of therapy for bladder cancer.

Objective: To investigate the effects of the cooperative actions of isoflavone, vitamin C and E on the expression of acute C reactive protein (CRP) and interleukin 6 (IL-6) in the patients with typeⅡdiabetic mellitus (DM). Method: Ninety six patients with DM were divided randomly into 4 groups, DM control group(B), and groups receiving low(C), medium (D) , and high (E) dose of the compound antioxidant of isoflavone, vitamin C and E respectively. Another 24 healthy subjects served as normal control group (A). Observe the changes of the levels of CRP and IL-6 during oral glucose tolerance test (OGTT). Results: The peak of serum levels of CRP and IL-6 in the patients of DM control group and lower dosage group appeared 1 h after OGTT and were significantly higher than the 0 h value (P

Objective To explore the effects of long-term Tai Ji exercise on risk factors of cardiovascular diseases and incidence of chronic diseases. Methods The elderly involved were divided into control group (n=62) and Tai Ji group (n=63). Both of them received 2-years health education. The Tai Ji group exercised with the frequency of 30~40 minutes each time, 3 times a week, while the control group didn't change their daily behavior. They were observed 2 and 6 years later. Results 2 years later, the blood pressure, weight and waistline decreased in Tai Ji group compared with the control group (P<0.05). After 6 years followed, 1 people died and 4 people occured cardiovascular diseases in Tai Ji group, while 2 people died and 12 people occured cardiovascular diseases in the control group. The incidence of chronic diseases was lower in Tai Ji group (9.52%) than in the control group (33.87%) (P<0.01). And the blood pressure, waistline, and hipline in Tai Ji group decreased significantly compared with the control group (P<0.001). Conclusion Long-term Tai Ji Exercise can ameliorate the risk factors of cardiovascular diseases and reduce the incidence of chronic diseases.

Aims To construct an expression vector of human lncRNA H 1 9 ,and to determine the effect of H1 9 overexpression on MCF-7 cell proliferation. Methods Total RNA was extracted from MCF-7 cells,and the full-length of H1 9 lncRNA was amplified by RT-PCR and subcloned into pcDNA3.1 (-)ex-pression vector.The constructed H1 9 expression vector was transfected into HEK-293T and COS-7 cells and the H1 9 lncRNA expression was evaluated by real-time PCR.Following the transfection of H1 9 expression vec-tor into MCF-7 cells for 0,24h and 48h and H1 9 siR-NA interference fragment into MCF-7 cells for 24h, MCF-7 cell proliferation was determined by MTS as-say.Results A hH1 9-pcDNA3.1 (-)expression vector was successfully constructed. At Forty-eight hours after the transfection with H1 9 expression vector in to MCF-7 cells,cell proliferation was significantly increased in the transfected group compared to those without transfection and to those transfected with a neg-ative control vector,while twenty-four hours after the transfection with H1 9 siRNA interference fragment into MCF-7 cells,cell proliferation was significantly de-creased in the transfected group compared to those transfected with a negative control vector.Conclusion Ectopic overexpression of H1 9 lncRNA can promote breast cancer MCF-7 cell proliferation.

Acquired chromosomal translocations can be identified in nearly 50% of human acute myeloid leukemias. The common chromosomal translocation in this disease is t(8;21) (q22;q22). It involves the aml1 (runx1) gene on chromosome 21 and the eto (mtg8, runx1t1) gene on chromosome 8 generating the aml1/eto fusion gene. An initial model for its pathogenesis emphasized the conversion of a hematopoietic transcriptional activator AML1 into a leukemogenic repressor which blocked myeloid differentiation at the level of target gene regulation. Aml1/eto fusion genes inhibit key hematopoietic transcription factor that function as tumor suppressors at several nodal point during hematopoietic differentiation. A new model is presented in which aml1/eto coordinates expansion of the stem cell compartment with diminished lineage commitment and with genome instability. In this review, the molecular role of aml1/eto fusion gene and his transcribed isoforms in regulating stem renewal, blocking hematopoietic differentiation and interacting with various lineage-specific transcription factors are summarized.

Objective To analyze the related factors of foot blisters caused by long-distance weight-bearing march and to explore the pathogenesis of foot blisters to provide a useful way for the prevention and treatment.Methods After the 300 km march,counted the number who had accomplished the march,and then recorded the number of foot blisters,location of blisters,and abrasion of sole.Collected the data of gender,age,body mass index (BMI),hand dominance,and whether had bliters before the march through questionnaire.And the data were coded for analysis with SPSS 13.0 statistical package.Results The 7 cases who complete the whole march and 17 cases who already had foot blisters before the march were ruled out of the final statistics.Among the remaining 590 cases,there were 554 cases (93.9%)suffered from foot blisters.And there were 1 282 blisters in total,among which the plantar blisters occupied 98% (1 257 cases).The analysis showed that the incidence of foot blisters had no significant correlation with gender,left/right foot,hand dominance,BMI and age.The predilection sites of blisters were the second and third metatarsals (28.2%),the hallux (21.3%),the fifth metatarsal (18.1%),and the calcaneus (15.8%)of the left foot.The predilection sites of blisters were the second and third metatarsals (33.3%),the hallux (22.4%),the fifth metatarsal (18.6%),and the calcaneus (14.5%)of the right foot.In terms of the abrasion of sole,the lateral heel was worn out the most (34.6% on the left and 34.2% on the right).Conclusion The study confirmed that the incidence of foot blisters had no significant correla-tion with gender,left/right foot,hand dominance,BMI and age,which may be affected by the particularity of this march.Most of the foot blisters occurred in the planta,and the predilection sites of blisters were in accord with sites of of the abrasion of sole and the distribution of plantar shear force,which demonstrated the shear force is the most critical factor on the pathogenesis of foot blisters.
