OBJECTIVE: To explore the clinical treatment effects of sea buckthorn oil for in different size traumatic perforation of tympanic membrane in different size. METHOD: Prospective, randomized study of 199 outpatients with traumatic perforation of tympanic membrane who were enrolled between December 2012 and December 2014 after informed consent. The patients were divided into treatment group (101 cases) and control group (98 cases). According to the size of the perforations, patients in each group were divided into large perforation group, middle perforation groups and small perforation group. The cases in large perforation group, middle perforation groups and small perforation group were 36, 34, 31 in treatment group and 35, 33, 30 in control group. The patients in treatment group were treated with sea buckthorn oil once a week, while the patient in control group were self-healing and checked once a week. All the patients were followed-up in two months. The healing rate of two groups was applied for the evaluation indicator of clinical effect. We compared the healing rate, average healing time and phological change of tympanic membrane of patients at the first and second month. RESULT: The total healing ratio of patients in treatment group is 62.4% and 79.2% compared with 29.6% and 57.1% in control group at the first and second month (P < 0.05). There is statistical significance between the healing ratios of middle, large perforation groups in treatment group and control group (P < 0.05). There is no statistical significance between the healing ratios of small perforation group in treatment group and control group (P > 0.05). The average healing time of large, middle and small perforation group at the second month are significantly shorter than the control group. CONCLUSION It is better to apply observation method and let it self-healed for small traumatic tympanic membrane perforation according to its higher healing ratio. While, it is better to apply sea buckthorn oil method for middle and large traumatic tympanic membrane perforation according to its lower healing ratios. Sea buckthorn oil treatment is benefitial for increasing the ratio of perforation healing, shorten the healing time, resumpting of the middle ear function earlier, helping most of the patients to avoid operation and the reduce medical expense. Therefore, it is valuable to promote the method in clinical treatment.

Ethanol tolerance of self-flocculating yeast SPSC01 was studied in a 3-L bioreactor under fed-batch culture. Yeast floc populations with the average sizes around 100, 200, 300, and 400 microm were obtained by adjusting the mechanical stirring rates of the fermentation system. When subjected to 20% (V/V) ethanol shock for 6 h at 30 degrees C, the remained cell viability was 3.5%, 26.7%, 48.8% and 37.6% for the aforementioned four floc populations, respectively. The highest ethanol yield 85.5% was achieved for the 300 microm flocs, 7.2% higher than that of the 100 microm flocs. The amounts of trehalose and ergosterol (including free ergosterol and total ergosterol) were positively correlated with the average size distributions from 100 to 300 microm. However, in the 400 microm flocs, the content of trehalose and ergosterol decreased, which coincided with its reduced ethanol tolerance compared to that of the 300 microm flocs. Furthermore, when subjected to 15% (V/V) ethanol shock at 30 degrees C, the equilibrium nucleotide concentration and plasma membrane permeability coefficient(P') of the 300 microm flocs accounted for only 43% and 52% respectively of those of the 100 microm and 200 microm populations. The effect of floc size distribution on the ethanol tolerance of the self-flocculating yeast strain SPSC01 was closely related to plasma membrane permeability. An optimal floc size distribution with the highest ethanol tolerance and ethanol production level could be obtained by controlling mechanical stirring speed of the bioreactor, which provides basis for the process optimization of fuel ethanol production using this self-flocculating strain.
