A cDNA sequence of Arnebia euchroma AP2/ERF named AeAP2/ERF was cloned by in silico cloning in this study, using ACX71873 sequence from Lithospermum erythrorhizon as the probe sequence. Some characters of the AP2/ERF gene and encoded protein sequences were predicted and analyzed by the bioinformatics methods, including general physical and chemical properties, hydrophobieity, signal peptide, secondary structure, localization sites in cells. Results showed that the 876 bp long gene included a 1 077 bp ORF and encoding 205 amino acid. The AeAP2/ERF protein had no signal peptide, it was a hydrophilic proteins located in nucleus. The function of the AP2/ERF protein was mainly involved with metabolism controlling and signal transduction.

A novel drug delivery system combining oral fast dissolving film with sodium deoxycholate/phospholipid mixed micelles was prepared to increase the absorption of cucurbitacin B that is a poor aqueous solubility substance. Encapsulation efficiency, particle size, zeta potential, polydispersity coefficient, investigated the morphology, disintegration time of oral fast dissolving film and the pharmacodynamic properties of cucurbitacin B sodium deoxycholate/phospholipid-mixed micelles before and after solidified in mice were evaluated and compared. The oral fast dissolving film prepared in this study showed a homogeneous pale yellow and could completely disintegrated in the 30 s. It could meet the requirements of rapidly disintegrating fully. The encapsulation efficiency, particle size, zeta potential, polydispersity coefficient of cucurbitacin B sodium deoxycholate/phospholipid-mixed micelles loaded in oral fast dissolving film were (43.36 +/- 2.12)%, (108.82 +/- 5.2) nm, (-34.18 +/- 1.07) mV, 0.088 +/- 0.012, respectively. The encapsulation efficiency, particle size, zeta potential, polydispersity coefficient of cucurbitacin B sodium deoxycholate/phospholipid-mixed micelles in solution were (41.26 +/- 2.22)%, (181.82 +/- 4.48) nm, (-30.67 +/- 0.81) mV, 0.092 +/- 0.012, respectively. The difference of pharmacodynamics among film of cucurbitacin B-loaded micelles, cucurbitacin B-loaded micelles and free cucurbitacin B in vivo was compared. Solubility of cucurbitacin B loaded in sodium deoxycholate/phospholipid-mixed micelles has also been greatly improved. The tumor inhibition rate of cucurbitacin B loaded in sodium deoxycholate/phospholipid-mixed micelles was significantly improved and did not change significantly before and after solidified. These showed that the sodium deoxycholate/phospholipid-mixed micelles could enhance the antitumor activities of cucurbitacin B and the stability of cucurbitacin B sodium deoxycholate/phospholipid-mixed micelles was improved significantly after solidified by oral fast dissolving film technology without pharmacodynamic properties changed significantly.

Objective To profile the phenotype and pathogens of cutaneous and mucous mycoses in a dermatology outpatient clinic in Nanchang region. Methods A review was performed to assess cutaneous and mucous mycoses diagnosed in the dermatology outpatient clinic of Dermatology Hospital of Jiangxi Province from 2006 to 2008. The relationship of clinical phenotype and pathogens to season, patients' age and gender was analyzed. Results A total of 7251 cases were collected, and the ratio of male to female patients was 2.3: 1. The most prevalent mycoses included tinea cruris (2702, 37.1%), pityriasis versicolor (1505, 20.8%) and tinea manus (727, 10.0%). In total, 4953 fungal strains were isolated from all the patients except for those with pityriasis versicolor, of them, Trichophyton rubrum accounted to 69.9%, Candida to 20.4%, and Trichophyton violaceum to 4.5%. Season, patients' age and gender were found to be associated with clinical phenotypes and pathogens of mycoses. Conclusions In the dermatology outpatient clinic of Nanchang region, tinea cruris is the most common superficial fungal disease, with the predominant pathogen being Trichophyton rubrum. Trichophyton violaceum is the primary pathogen of tinea capitis, which is different from other reports.

In recent years, polysaccharides have received much attention because of their high safety and good immunological activity. The study of polysaccharide in vivo process is a key scientific problem that needs to be solved for polysaccharide drug development. Some progress has been made in the field of polysaccharide pharmacokinetics and immunomodulation. However, due to the lack of both chromogenic and light-absorbing groups and the complex molecular structure of polysaccharides, the in vivo processes and immunomodulatory mechanisms of polysaccharides have been slow to be investigated. The effective combination of multiple techniques can break the bottleneck of difficult tracing and unknown immunomodulatory mechanism of polysaccharides in vivo, and promote the development and utilization of polysaccharides. In this paper, we systematically summarize the key techniques in the study of polysaccharide in vivo processes and immunomodulatory mechanisms in order to provide technical references and research ideas for the study of polysaccharide in vivo processes and immunomodulatory mechanisms.

OBJECTIVETo investigate results of total knee arthroplasty using the long-stem tibial component combined with metallic wedge of knee prosthesis for the treatment of proximal defects.

METHODSFrom January 2011 to May 2013, 10 patients (11 knees) were treated with total knee arthroplasties using the long-stem tibial component with metallic tibial wedge of knee prosthesis. All the patients were female and the average age was 67 years old (ranged, 60 to 77 years old). All the patients were osteoarthritis. All the patients were classified as T2A style. The patients were evaluated according to knee score system (KSS).

RESULTSAll the patients were followed up for 12 months on average (ranged 3 to 29 months). The clinical outcome was assessed using KSS score, including knee pain score, knee stability score, knee range of motion score and knee walking score, knee stairs score. There were significantly differences at 6 weeks, 3 months, 6 months and 12 months between pre-and postoperative KSS score.

CONCLUSIONThe mechanical stability of tibial fixation in primary TKA is significantly increased by using the long-stem tibial component with metallic wedge of knee prosthesis, even in the presence of poor proximal bone.

OBJECTIVETo detect CCL20 and CXCR4 expressions in epidermis infected with condyloma acuminatum (CA) and normal epidermis and investigate the effect of their expressions on Langerhans cells in CA epidermis.

METHODSGene expression of CCL20 and CXCR4 in 3 epidermal CA lesions and in 3 normal epidermis specimens were detected using Affymetrix oligonucleotide microarrays HG-U 133A 2.0, and the protein levels of CCL20 and CXCR4 in these specimens were measured by Western blotting.

RESULTSMicroarray analysis revealed markedly down-regulated mRNA expressions of CCL20 and CXCR4 in the 3 epidermal CA lesions as compared with those in the normal specimens. Western blot analysis showed that the protein expressions of CCL20 and CXCR4 in the CA lesions were significantly lower than those in normal epidermis.

CONCLUSIONThe protein and mRNA expressions of CCL20 and CXCR4 are markedly down-regulated in epidermal CA lesions, which may contribute to decreased number and backflow disturbance of Langerhans cells in these lesions.
