This paper reported a new method of Armillaria mellea isolation-Gastrodia elata tissue isolating. Compared with normal isolating method-rhizomorph isolating method, it showed that the success rate of new method (78% ) was higher than the rhizomorph isolating method (16% ) , besides this, the new method was easier, and growth characteristic of obtained strain was superior to that obtained from rhizomorph isolating method.

A coupling principle of reflecting impedance based on resonance is designed to achieve impedance detection with high sensitivity. It is characterized by small impelled current, high sensitivity and simple circuit. The principle can be used not only in detecting human respiratory impedance, but also in detecting the bio-impedance of other human organs. It may find wide application in this aspect.

Objective To study the role of cell density in the tyrosol production and morphology for Candida albicans biofilms. Methods C. albicans SC5314 and clinical isolates were propagated in yeast peptone dextrose (YPD) medium. Cells were collected by centrifugation and washed twice in sterile phosphate-buffered saline (PBS) before this study, then resuspended in RPMI 1640 supplemented with L-glutamine and adjusted to a desired concentration of 5 × 10~6 cells/ml, 5×10~5 cells/ml, 5 × 10~4 cells/ml, 5 × 10~3 cells/ml after counting with a hematocytometer. Standardized C. albicans cells were prepared as above description and 2000 μl of this standardized cell suspension was dispensed into the wells, then C. albicans biofilms were formed on the bottom of the polystyrene wells. In this study, tyrosol synthesized by SC5314 and clinical isolates of C. albicans biofilm was quantified by high performance liquid chromatography (HPLC). The effects of tyrosol on morphology of C. albicans biofilms were investigated by scanning electron microscopy (SEM). Results Tyrosol production of C. albicans biofilms was affected by cell densities. At lower inoculation size(5 μ 10~3 cells/ml), there was too less tyrosol production to be detected at the early stage of the biofilms formation. At higher inoculation size (5 μ10~6 cells/ml), tyrosol can be detectable at the early stage or at the mature stage of biofilms formation. There was a sharp increase in tyrosol concentration at 24 h, while there was a decrease in tyrosol concentration after that time from the strains when the strains were at an inoculation size of 5 × 10~6 cells/ml and 5 × 10~5 cells/ml. Cell densities affected the morphology formation of the C. albicans biofilms. At the early stage of the biofilms formation, C. albicans grew less germ tube at lower cell densities than that at the higher cell densities. With the mature of the biofilms, C. albicarts grew more hyphae at higher cell densities than that at the lower cell densities. All these above showed that cell densities played an important role in the propagation for the C. albi-cans in the biofilm formation. Conclusion Cell density play an important role in the formation of the C. albi-cans biofilms and the production of the tyrosol.

Objective To evaluate the cytogenetic, molecular responses and safety of generic imatinib in newly diagnosed patients with chronic myelogenous leukemia in chronic phase (CML-CP) in 1-year at different stages. Methods From January 2014 to November 2014, 50 CML-CP patients received oral generic imatinib 400 mg/d. The cytogenetic examinations, bcr-abl transcript levels and safety were monitored after 3, 6, 9 and 12 months respectively. Results 46 of 50 patients insisted on oral generic imatinib and followed up 1 year. At 3-month, 52.0 % (26/50) patients reached the complete hematologic responses (CHR) rate, and patients at least achieved minor cytogenetic response (mCyR) and bcr-ablIS≤10 % were 84.0 % (42/50) and 42.0 % (21/50). At 6-month, patients at least achieved part cytogenetic response (PCyR) and bcr-ablIS≤10 %were 73.5 % (36/49) and 59.2 % (29/49). At 12-month, patients achieved complete cytogenetic response (CCyR), bcr-ablIS≤1 % and bcr-ablIS≤0.1 % were 60.9 % (28/46), 63.1 % (29/46) and 45.7 % (21/46). The grade 3 leukopenia, thrombocytopenia and anemia rates were 34 % (17/50), 40 % (20/50) and 30 % (15/50), respectively. No grade 4 hematologic toxicity occurred. The common non-hematologic toxicities included edema [84 % (42/50)], nausea [46 % (40/50)], muscle pain [20 % (10/50)], rash [16 % (8/50)], and impaired liver function [8 % (4/50)]. Conclusion Generic imatinib has a favorable effect in treatment of patients with CML-CP, and without serious adverse reactions.
