To investigate the role of immediate-early gene c-fos in sodium selenite-induced apoptosis and its position in a possible cascade of apoptogenic genes, we compared the time-courses of expression for 5 related genes, including c-fos, during the apop- tosis induced by sodium selenite with or without blockage of c-fos expression by adding c-fos antisense oligodeoxynucleotide ( ASO) in cultured cortical neurons. The results showed that: (1) in control experiments without c-fos ASO adding, 0. 5 μmol/ L sodium selenite-induced apoptosis as revealed by electrophoretic and flow cytometric examinations; at the same time, sodium selenite also induced down-regulation of bcl-2 mRNA expression and up-regulations of mRNAs related to bax, c-fos, p53, and acetylcholinesterase (AChE) genes; (2) in similar experimental conditions with c-fos ASO cotreatment, the sodium selenite-in- duced apoptosis was blocked with the up-regulation of p53 expression still emerging as before, while the changes in expressions of bcl-2, bax, AChE genes were reversed at the same time. The results suggest that c-fos ASO could play a protective role upon cortical neurons from suffering apoptosis induced by sodium selenite, and there might exist a cascade of gene expressions with p53 and c-fos genes being regulated upstream and then bcl-2, bax, and AChE genes being regulated downstream.

OBJECTIVE: To evaluate the anxiety and depression status of patients with nasal septum deviation before and after surgery, and explore the relationship between anxiety and depression and nasal symptoms. METHOD: By means of visual analogue scale (VAS) as the evaluation index of quality of life, self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to analyze statuses before and after surgery. The 98 patients with nasal septum deviation were collected. RESULT: The preoperative SAS/SDS scores of the nasal septum deviation patients were higher than those of the national standards. The level of anxiety and depression were lower than the national norm after treatment. The patients of the normal and moderate SAS/SDS scores felt better after surgery. The patients of the severe SAS/SDS scores felt the symptoms improve poor. CONCLUSION Doctors should pay attention to the application of the SAS/SDS in patients of nasal septum deviation. Surgeon should actively communicate with severe patients in psychological problems, and strictly control the surgical indication of such patients.

In this study, we use pot experiment to evaluate the effect of plant growth regulator on plant morphology and biomass allocation of Salvia miltiorrhiza. Different concentrations of uniconazole were supplied to S. miltioohiza by means of foliar spray. Height, breadth and stem diameter were measured dynamically, the biomass of leaf, stem, flower and fruit, root biomass and biomass ratio were also examined at the harvest time. Owing to the treatment, plant morphology showed significant changes, the height had been greatly reduced and the breadth decreased largely. Meanwhile, the biomass allocation changed too. The biomass ratio of leaf and stem had been notably reduced while the biomass ratio of root had been increased remarkably. It appears that foliar application of uniconazole during vigorous growth period in S. miltioohiza has dramatic effect on dwarfing plant and improving resistant to lodging. This measure could also be applied to condensed cultivation of S. miltioohiza to increase production.
