To providing evidence about nitrogen adequate application of Platycodon grandiflorum, the pot culture experiment was conducted to study the effect of nitrogen on the growth, physiological metabolism and the quality of P. grandiflorum. The activity of NR, GS and SOD, POD and CAT were determined. And the nitrate and ammonium nitrogen content, photosynthetic characteristics, active components of P. grandiflorum were determined. The results showed that the nitrate nitrogen content and P. biomass reached its maximum value, when NH4(+)-N/NO3(-) -N was 0: 100, the activity of NR. The activity of GS was the highest at the NH4(+) -N/NO3(-) -N ratio of 25:75 and ammonium nitrogen content was the highest at 75:25. The activity of SOD decreased and then increased with the increasing of NO3(-) -N. At the NH4(+) -N/NO3(-) -N ratio of 25: 75, the activity of CAT had its maximum value and the content of MDA had the minimum value. At the same time, the content of platycodon D was the highest at this treatment. The studies had shown that different nitrogen forms and ratio had a significant effect on the characteristics of photosynthetic physiology, nitrogen metabolism and resistance adjustment, growth and the quality of P. grandiflorum. The NH4(+) -N/NO3(-) -N ratio of 25: 75 was a suitable ratio of nitrogen forms for the growth of P. Grandiflorum and accumulating the content of platycodon D.

OBJECTIVES: Some emotional components, such as self-esteem, depression and anxiety, have been reported to be associated with paranoia in non-clinical population and schizophrenia patients. The aim of this study was to investigate the correlation between self-esteem and paranoia in healthy controls, in ultra-high risk for psychosis and schizophrenia patients. METHODS: 34 subjects with recent onset schizophrenia, 36 subjects with ultra-high risk for psychosis, and 44 healthy volunteers participated in this study. A detailed assessment was made of the paranoia, self-esteem, depression, and anxiety. RESULTS: In all three groups, there were a negative correlation between paranoia and self-esteem, and positive correlations between paranoia and depression and anxiety. In healthy control, lower self-esteem showed a trend to predict higher paranoia, and in ultra-high risk for psychosis, this trend tern on statistically significant level, and in recent onset schizophrenia group, this correlation was disappeared. CONCLUSION: The individual who have lower self-esteem showed higher paranoia tendency under delusional level, but after formation of persecutory delusion, the tendency was disappeared. This result supports the hypothesis that persecutory delusions are a defense against negative affective process.

Calcaneal fractures involving subtalar joint can be associated with prolonged and severe disability. Many different methods have been tried for the treatment in order to search for better results. From March 1983 to December 1985, 8 cases of calcaneal fractures involving subtalar joint were treated by open rcduction and internal fixation. and the results were as follows: 1. Satisfactory results were obtained from 7 cases out of 8. 2. Anatomic reduction was obtained by open reduction and internal fixation. 3. When medial approach failed, combined lateral and medial approaches gave better visualization of articular fecets and ensured anatomic reduction.

This study was purposed to analyze the clinical characteristics of multiple myeloma (MM) patients with and without renal impairment (RI) and to investigate the effect of bortezomib (Bor) on MM with RI. Clinical data of 39 MM patients (15 cases with RI, 24 cases without RI) received treatment of Bor in department of hematology in our hospital from Jan 2007 to Aug 2011 were collect and analyzed in term of clinical characteristics, curative efficacy, outcome of renal impairment and toxic reaction associated to chemotherapy. The results showed that (1) the obvious difference of the disease type, the creatinine, uric acid, serum calcium and β2-microglobulin levels existed in patients with and without RI, while there were no significant difference in hemoglobin and globin levels; (2) there were no significant difference in overall reaction rate and overall survival rate between MM patients with and without RI, however the median survival time of patients without RI was longer than that of patients with RI; (3) the RI could be reversed after the treatment with Bor, and the effect was most obvious after the first cycle. 20% MM patients with RI had recovered from RI after the first cycle; and the recovery rate from RI got up to 38.4% after the second cycle. The decline of creatinine levels had no difference between MM patients with or without RI after the second cycle. (4) The adverse events included gastrointestinal symptoms, peripheral neuropathy, thrombocytopenia and infection. There was also no difference between the 2 groups. It is concluded that Bor-based regimens for the MM patients with RI are effective and safe, and the renal function would be reversed after 2 cycle of Bor-based regimen.

Purpose To investigate the relations of THEM4/Akt expression and extracellular matrix deposit in kidney of diabetic mice. Methods Diabetic mice models were successfully established by intraperitoneally injected STZ. Both normal control mice and diabetic mice were raised for 8 week until they were sacrificed. Western blot, immunohistochemistry and realtime PCR were used to detect the expression of THEM4, phospho-Akt (Ser 473), TGF-β1, a-SMA, Col Ш, FN protein and THEM4 mRNA in the kidneys of normal mice and diabetic mice. Results Compared to normal control mice, THEM4 expression decreased by 37.7% followed by 3.66, 1.29 2.33, 1.99 and 2.82 times increased of phospho-Akt (Ser473), TGF-β1, a-SMA, Col Ш and FN in kidney of diabetes mellitus. Extracellular matrix accumulation was found in renal interstitial region of diabetic mice. Conclusion The decreased THEM4 might cause extracellular matrix deposit in kidney of diabetic mice by upregulating the phosphorylation of Akt and TGF-β1, α-SMA expression in diabetic mice.

A beta-glucan synthase gene was isolated from the genomic DNA of polypore mushroom Sparassis crispa, which reportedly produces unusually high amount of soluble beta-1,3-glucan (beta-glucan). Sequencing and subsequent open reading frame analysis of the isolated gene revealed that the gene (5,502 bp) consisted of 10 exons separated by nine introns. The predicted mRNA encoded a beta-glucan synthase protein, consisting of 1,576 amino acid residues. Comparison of the predicted protein sequence with multiple fungal beta-glucan synthases estimated that the isolated gene contained a complete N-terminus but was lacking approximately 70 amino acid residues in the C-terminus. Fungal beta-glucan synthases are integral membrane proteins, containing the two catalytic and two transmembrane domains. The lacking C-terminal part of S. crispa beta-glucan synthase was estimated to include catalytically insignificant transmembrane alpha-helices and loops. Sequence analysis of 101 fungal beta-glucan synthases, obtained from public databases, revealed that the beta-glucan synthases with various fungal origins were categorized into corresponding fungal groups in the classification system. Interestingly, mushrooms belonging to the class Agaricomycetes were found to contain two distinct types (Type I and II) of beta-glucan synthases with the type-specific sequence signatures in the loop regions. S. crispa beta-glucan synthase in this study belonged to Type II family, meaning Type I beta-glucan synthase is expected to be discovered in S. crispa. The high productivity of soluble beta-glucan was not explained but detailed biochemical studies on the catalytic loop domain in the S. crispa beta-glucan synthase will provide better explanations.
