Objective: The NaCl stress conditions were simulated to study the effect of the endophytic fungi C1, C4 on antisalty characteristic of Chrysanthemum morifolium in the adverse circumstance. Methods: Endophytic Botrytis sp. (C1) and Chaetomium globosum (C4) were inoculated to the C. morifolium plantlets which were planted in the pots in order to research the effects of salt stress on physiological indicators of C. morifolium. Results: With the increase of NaCl concentration, the water content of root and leaf decreased in every group. The loss of root and leaf's water in fungi-treated group was smaller than that in the control group. SOD activities in every group increased with the increase of NaCl concentration, and achieved the peak value at 20 g/L NaCl. The SOD activity in fungi-treated group was higher than that in the control group. Soluble protein of fungi-treated group was higher than that in the control group, and C4 group surpassed C1 group. POD activity increased firstly and then decreased, and compared to the control group, the POD activities in C4 and C1 groups increased by 25.50% and 1.35%, respectively at 15 g/L NaCl. PAL activity of C4 treated group was seven folds compared to the control group at 15 g/L NaCl. Conclusion: Endophytic fungi could enhance the salt-tolerant ability of C. morifolium, and the effect in C4 group was better than C1 group.

OBJECTIVE: To evaluate the function of tubomanometry (TMM) in forcasting the progonosis of acute otitis media with effusion (OME). METHOD: We used the technique of TMM to quantify the degree of eustachian tube (ET) dysfunction in 65 patients with OME. The opening of the ET and the transportation of gas into the middle ear were registered by a pressure sensor in the occluded outer ear after applying the stimulus of a controlled gas bolus into the nasopharynx during swallowing. Three excess pressure values were tested subsequently (30, 40, and 50 mbar). If tube opening was registered, the time of opening in relation to pressure applied was measured. The TMM calculated the opening latency index or index R. An R value of < 1 indicated early opening of the tube at the start of application of the stimulus, which was considered optimal. A value > 1 indicated late opening of the tube occurring after the initial stimulus and was interpreted as suboptimal. Inability to calculate the index R value indicated that the tube was unable to actively open at all. The TMM results, were weighted as follows: no R with 0 points, R > 1 with 1 point and R < 1 with 2 points for the measurements at 30, 40, and 50 mbar, respectively. The points of these three tests were added so the ET score (ETS) ranges from 0 (worst value) to 6 (best value). According to the medical history, the patients were divided into two groups, chronic OME group (defined as positive control group), 30 cases with 38 ears; and acute OME group, 35 cases with 46 ears. The healthy ears of all patients were defined as normal control group, 46 cases with 46 ears. The same regular treatments, including classic medical treatments and intratympanic dexamethasone injections, were used to acute OME group in the following 1-2 months. On the basis of therapeutic effect, acute OME group was subdivided into valid group (26 cases with 33 ears) and invalid group (9 cases with 13 ears). RESULT: The ETS of normal control group was 5.11 ± 1.32 while it was 1.08 ± 1.32 in positive control group. It was found marked differences between the two groups (P < 0.01). The ETS of both valid and invalid subgroup of actue OME group were significantly lower than normal control group (P < 0.01), but in valid subgroup it was significantly higher than positive control group (P < 0.01), and no marked difference was found between the invalid subgroup and positive control group. After treatments, a significant improvement of the ETS was found in both valid and invalid subgroup (P < 0.05) there was no marked difference between valid subgroup and normal control group. But in invalid subgroup it was still significantly lower than normal cohtrol group (P < 0. 01). CONCLUSION TMM could forecast the prognosis of acute OME. Patients with acute OME suffered from ET dysfunction of varied degrees. Those with high ETS could be cured by classic medical treatments and intratympanic dexamethasone injections. But those with poor ETS could not be cured in short period, tube insertion should be considered. If ETS could not be improved by ventilation tube placement, more active treatment, for example, balloon Eustachian tuboplasty (BET), should be used to prevent transforming into chronic OME.

?AIM:To study the clinical value of non-steroidal anti-inflammatory drug in adjuvant treatment of intravitreal triamcinolone acetonide ( IVTA ) for macular edema caused by retinal vein occlusion ( RVO) .?METHODS: Forty - eight eyes in 48 patients were randomly divided into trial and control group ( 24 eyes each ) in this prospective study. In the trial group, additional pranoprofen drops was administered from 1d before IVTA to 30d after injection. Central foveal thickness ( CFT ) was measured with optical coherence tomography ( OCT ) . Available documents of best corrected visual acuity ( BCVA ) , CFT, intraocular pressure and complications pre- and post-injection at 3d, 1,2wk, 1 and 3mo were evaluated.?RESULTS: After IVTA, BCVA was improved in both groups at different levels; but there was no statistically significant between two groups at each time point ( P>0. 05). The CFT values were 629 ± 43μm vs 605 ± 57μm before IVTA in the trail vs control groups (P>0. 05). The values were 432±74μm vs 511±32μm (t=7. 533, P<0. 05), and 275±54μm vs 379±29μm (t=13. 212, P<0. 05) of the trial vs control groups at 1 and 3mo after IVTA, respectively. Ocular hypertension occurred in 5 eyes after injection in trail group, and was controlled with anti-glaucoma medication and one eye with filtration surgery. Progression of cataract was noted in 3 of 35 phakic eyes and cataract surgery was performed in 2 eyes at 4-12mo after injection in trail group. Progression of cataract was noted in 4 eyes and cataract surgery was performed in 2 eyes at 4- 12mo after injection in control group. No retinal detachment and endophthalmitis happened during the whole period of follow-up.?CONCLUSION: Application of non - steroidal anti -inflammatory eye drops in perioperative period can be useful to improve the outcome of IVTA for macular edema, which needs further evaluation.
