Objective To evaluate the clinical effect of dual-plate for treatment of comminuted distal humerus fractures in adult. Meth-ods 28 patients with distal humeral fractures were treated with condylar anatomical plate interal fixation. The supracondylar fracture was fixed with condylar anatomical plating, and the two plates were kept in 90°with each other. Results The 28 cases were followed up average-ly 26 months (12 to 34 months). All fractures healed and there was no delayed union or nonunion cases. According to Cassebaum scoring system, there were 9 cases of excellent,14 cases of good, 4 cases of moderate and 1 case of bad. According to Morrey-Chao scoring system, there were 16 cases of cases,11 cases of good. The average time of bone healing was 10 weeks. Conclusion In treatment of comminuted distal humerus fractures in adult, open reduction and dual-plate internal fixation can get good clinical results. The placement of the dual-plate may depend on surgeon experience and preference and the fracture pattern present.

Flocculent gene FLO1 and its truncated form FLO1c with complete deletion of repeat unit C were expressed in a non-flocculent industrial strain Saccharomyces cerevisiae CE6 to generate recombinant flocculent strains 6-AF1 and 6-AF1c respectively. Both strains of 6-AF1 and 6-AF1c displayed strong flocculation and better cell growth than the control strain CE6-V carrying the empty vector under acetic acid stress. Moreover, the flocculent strains converted glucose to ethanol at much higher rates than the control strain CE6-V under acetic acid stress. In the presence of 0.6% (V/V) acetic acid, the average ethanol production rates of 6-AF1 and 6-AF1c were 1.56 and 1.62 times of that of strain CE6-V, while the ethanol production rates of 6-AF1 and 6-AF1c were 1.21 and 1.78 times of that of strain CE6-V under 1.0% acetic acid stress. Results in this study indicate that acetic acid tolerance and fermentation performance of industrial S. cerevisiae under acetic acid stress can be improved largely by flocculation endowed by expression of flocculent genes, especially FLO1c.

OBJECTIVE To investigate the effects of recombinant human epidermal growth factor (rhEGF) on wound healing of chronic sinusitis patients after functional endoscopic sinus surgery. METHODS A total of 110 patients with chronic sinusitis underwent functional endoscopic sinus surgery with both sides of their nose. The right side of their nasal cavity (control group) treated by nasal irrigation and steroid nasal spray, the left side of their nasal cavity (study group) treated by nasal irrigation and the nasal spray of steroid hormones and rhEGF. Surgical effect was evaluated under nasal endoscope at 2, 4, 12 and 24 weeks after surgery, while subjective symptom was evaluated depending on visual analogue scale (VAS). Both the score of endoscopic examination and VAS, also the rates of epithelization of the two groups were compared. RESULTS The score of endoscopic examination of the study group at 2 weeks after surgery was better than that of the control group, which had statistical significance, while the score of VAS had no statistical difference. The score of endoscopic examination and VAS, the rate of epithelization in study group at 4 and 12 weeks after surgery were better than those in control group, and the difference was statistically significant, but they were no statistical difference at 24 weeks after surgery. CONCLUSION The using of rhEGF nasal spray on chronic sinusitis patients with functional endoscopic sinus surgery can shorten the time of epithelization, improve the situation of nasal mucosa and patients' subjective symptoms, it is worthy of clinical application.

Aim To screen the differentially expressed microRNAs ( miRNAs ) induced by hypoxia precondi-tioning ( HPC ) in adult rat cardiomyocytes, and pre-dict miRNAs-regulated target genes and their func-tions. Methods Cardiomyocytes were isolated from a-dult rat ventricular myocardium and cultured ( in vitro) . The cells were divided into 2 groups: control group ( CON ) and hypoxia preconditioning group ( HPC) . The cardiomyocytes in HPC group were sub-jected to 10 min hypoxia followed by 30 min reoxygen-ation, while the cells in CON group were cultured un-der normal condition. After that, total RNA was ex-tracted and then subjected to miRNA microarray to screen differentially expressed miRNAs. The microar-ray results were further validated by quantitative RT-PCR ( qRT-PCR ) . Bioinformatics analysis was per-formed to predict the miRNAs-regulated target genes and analyze the enriched gene ontology ( GO) and sig-naling pathway ( Pathway) . Results HPC caused sig-nificant changes in miRNAs expression in cardiomyo-cytes as compared to CON group. A total of 12 miR-NAs were up-regulated and 14 miRNAs were down-reg-ulated ( P <0. 01 , FDR <0 . 05 ) . The differentially expressed 7 miRNAs with a fluorescent signal intensity>500 were selected for further bioinformatics analysis. The expression of miR-133b-5p, miR-664-1-5p and miR-6216 detected by qRT-PCR exhibited the similar patterns of up or down regulation to those shown in mi-croarray results. Bioinformatics analysis revealed that miRNAs-regulated target genes were significantly en-riched in 27 GOs and 6 signal pathways. Conclusion
The expression profile of miRNAs in rat cardiomyo-cytes is significantly affected by HPC. These differenti-ally expressed miRNAs might participate in HPC-in-duced cardioprotection by regulating their target genes in rat cardiomyocytes.
