Objective To observe the effect of transduetion of human wild type gene(wt-p53) mediated by recombinant adenovirus on cell growth, cell cycle and apoptosis of neuroblastoma (NB) cell line SH-SY5Y. Methods The NB cell line SH-SY5Y were transfected by recombinant adenovirus with green fluorescent protein(Ad-GFP). The suitable muhiplieity of infection (MOI) was determined after trans-fer efficiency was tested by flow cytometry (FCM). Both recombinant adenovirus(Ad) and recombinant adenovirus mediating wt-p53 gene (Ad-p53) were transfected into SH-SY5Y cells. SH-SY5Y cells without any transfection were used as blank group. The p53 protein expres-sion was validated by Western blot. Cell number was counted and growth curve was drawn. Both cell cycle and apoptesis were detected by FCM. Results The results indicated that the transfer efficiency of recombinant adenovirus to SH-SY5Y was satisfied, and 100 MOI was suitable. After transfection with Ad-p53, p53 protein was high expressed. Cell growth were inhibited, apoptosis and cell cycle arrest were in-duced in p53 gene transfeetion group. Conclusions Our results indicate that clinical application of the in vitro p53 gone modified tumor cell vaccine might be feasible and effective in clinical treatment of NB.

Sarcopenia is closely related with age-related loss of muscle fiber, reduced physical activity, hormone level decline and nutrition deficiency. Though torque generation in knee extension, relative skeletal muscle index, lean body weight, electromyogram, gait analysis, grasp force, nuclear magnetic resonance and B ultrasonic examination are generally accepted as diagnostic method, there is not an unified standard in diagnosis. Through the physical activity and diet can prevent and reverse the tendency of sarcopenia, which also improve the activity of the hypothalamic-GH-insulin-like growth factor-1 axis. In future, the characteristic therapy of Chinese medicine science can be added into resistance exercise and nutrition method, or combined compound hormones with nutrition intervention to design orthogonal test for seeking the best interaction, and explore the long-term safety and effectivity by follow-up observation.

Objective To construct and express fusion toxin human IL15 mutant/TNF? mutant (hIL15M/TNF?M) in order to develop a targeted toxin capable of eliminating abnormal cells expressing high levels of hIL15 receptors. Methods DNA fragments of truncated hIL15M and TNF?M coding gene were joined in frame and cloned into T7 expression vector pET16b. The expressed fusion protein was purified from E. coli . Cytotoxicity of hIL15M/TNF?M was measured by MTT assay. Results E. coli transformed with the recombinant plasmid expressed an extra band with the expected size of 30?10 3. MTT assay indicated that PHA activated T cells were 13 times more sensitive to the cytotoxic effect of hIL15M/TNF?M than to the resting T cells. Conclusion hIL15M/TNF?M has high toxic effect against cells expressing high levels of IL15 receptors, suggesting that hIL15M/TNF?M has potential therapeutic effect on T cell leukemia and other diseases related with improperly activated T cells.

Objective To compare knowledge about hypertension between elderly Chinese urban patients with preferences for either traditional Chinese medicine (TCM) or Western medicine (WM).Methods Elderly (≥ 65 years old) patients with hypertension who prefer TCM treatment (n=112) or WM (n=126) were questioned about hypertension.Their answers were compared.Results Only 32.6% of participants correctly identified hypertension as a main risk factor of coronary heart disease and stroke,22.3% of patients answered that the main purpose of hypertension control was preventing cardiovascular disease.Other major reasons for these patients to seek medical treatment for their hypertension included:persuasion by physicians or their family members (21.6%),alleviating symptoms such as headache and dizziness (16.8%),lowering blood pressure without knowing specific reason (12.4%).The predictors for poor knowledge of hypertension were similar irrespective of preference for WM or TCM treatment,and included those with lower levels of education and older age.Television and newspaper (46.8%) were the most frequent sources of hypertension information for both groups.Among those who preferred TCM treatment,TCM has fewer side effects than WM and TCM cures disease while WM only alleviates symptoms were common beliefs held.Conclusion This study shows that knowledge of hypertension is similar among Chinese urban patients with preferences for either WM or TCM treatment and that misunderstandings about hypertension are common among the elderly patients.In order to control hypertension effectively,public health education is necessary.This should target those with a lower level of education and older age.
