OBJECTIVE: To understand the vowel duration and statement reading of the adductor spasmodic dysphonia (ADSD) patients compared with their normal controls, and provide ideas for clinical diagnosis and treatment. METHOD: Twenty-nine ADSD patients were included in the research, with 31 normal controls. All subjects filled in form voice handicap index (VHI) by themselves. Maximum phonetic time (MPT) and maximum loudness phonetic time(MLPT) were tested on /a/ sound for all patients. Also, all the patients were required to read aloud a standard mandarin assay named , duration were measured with Praat5. 0 software after sounds were collected. A one-way t-test was performed to compare spasmodic group with control group on VHI, MPT, MLPT and duration for reading standard sentences. Pearson/Spearman correlation was tested. Result: The VHI of the 29 ADSD patients is 89±12, and their normal controls 15±16, indicating that the VHI in ADSD group is significantly higher than in the control group(P<0. 01). The MPT of the ADSD group is(16. 9±9. 8 s), and the control group is (25. 3±10.0)s, indicating that MPT in the ADSD group is significantly shorter than the control group(P<0. 01). The MLPT of the ADSD group is (15.7±7. 6)s, and the control group is (26. 5±11. 4)s, indicating that MLPT in the ADSD group is significantly shorter than the control group (P<0. 01). The duration of standard sentence reading of the ADSD group is (55.0±14. 2)s, and the control group is (37. 8±4. 8)s, indicating that the duration of standard sentence reading in the ADSD group is significantly longer than the control group (P<0. 01). Correlation analysis showed that MPT and MLPT are related within the ADSD group(r=0. 697,P< 0.01), other indexes being tested have no significant correlations. CONCLUSION The voice disorder condition of the ADSD patients is significantly worse than normal people. Their pronunciations on continuous vowels are not lasting compared with normal people. In the meantime, their ability to read sentences is worse than normal people, needing longer time to complete the reading task. There is a significant correlation between MLPT and MPT, which can be used as an alternative to MPT.

OBJECTIVETo investigate the effect and its indication of orbital fat flap for treating sunken upper eyelid in middle-aged and elder patients.

METHODSThe upper middle orbital fat was transferred to the sunken area as a flat flap to correct Sunken upper eyelid at grade I, II, III. The depression depth was graded as I (<0.5 cm), as II (0.5-1.0 cm), as III ( >1.0 cm). From April 2011 to April 2012, 66 cases were treated and 49 cases were followed up for 12-15 months.

RESULTSAll patients with sunken upper eyelid were successfully treated using this procedure and no complications were encountered. Fat absorption was not observed. The effective rate was 90.9% (20/22) for grade I , 31.0% (18/58) for grade II and 0 for grade III (0/18), showing significant difference between any of two groups (P<0.05).

CONCLUSIONSThe orbital fat flap is effective for grade I Sunken upper eyelid with long- term effect.

Using the weight-average molecular weight 50 000 polylactic acid (PLA) as a carrier, and a certain proportion of erythromycin (EM) and prednisone acetate (PNA) to mixed prepare the compound erythromycin sustained release preparation (sustained-release tablets). Using ultraviolet spectrophotometry and high performance liquid chromatography (HPLC) to detect separately the release amount of EM and PNA in vitro medium. The sustained-release tablets release for about 21 days, the average content of EM is 99.7 mg/table, RSD = 0.82%; and the average content of PNA is 10.03 mg/table, RSD = 0.93%. Within 21 days, the cumulative releases of EM and PNA are 86.1% and 78.3%, respectively. The drug release is steady and slow after 5 days, the burst release phenomenon in early stage is more significant. The results showed that the sustained-release tablet preparation method is feasible, the release performance is good and the clinical efficacy is significant.

This study is to prepare the microemulsion-based gel based on the W/O microemulsion and fluorouracil (5-Fu) as a model drug to study the transdermal characterization and observe its skin irritation of the microemulsion-based gel in vitro. IPM acted as oil phase, AOT as surfactant, Tween 85 as cosurfactant, water was added dropwise to the oil phase to prepare W/O microemulsion at room temperature using magnetic stirring, then 5-Fu powder was added. The gelatin was used as substrate to prepare 5-Fu microemulsion-based gel. The permeation flux of 5-Fu from 5-Fu microemulsion-based gel across excised mice skin was determined in vitro using Franz diffusion cell to study the influence of the amount of gelatin and the drug loading capacity. Refer to 5-Fu cream, the irritation of microemulsion and microemulsion-based gel on the rat skin was studied. Based on the water/AOT/Tween 85/IPM microemulsion, only the gelatin can form the microemulsion-based gel. At 25 degrees C, 32 degrees C and 40 degrees C, the amount of gelatin required for the formation of microemulsion-based gel were 7%, 14% and more than 17%, respectively. The 12 h transdermal cumulated permeation amount of 5-Fu from microemulsion-based gel containing 14% gelatin and 0.5% drug loading were (876.5 +/- 29.1) microg x cm(-2), 12.3 folds and 4.5 folds more than 0.5% 5-Fu aqueous solution and 2.5% (w/w) 5-Fu cream, respectively. Microemulsion-based gel exhibited some irritation, but could be subsided after drug withdrawal. Microemulsion-based gel may be a promising vehicle for transdermal delivery of 5-Fu and other hydrophilic drug.

Objective To investigate the effects of miR-100 on the proliferation of MIA PaCa-2 and CFPAC-1 cells through targeting fibroblast growth factor receptor 3 (FGFR3).Methods miR-100 expression levels in 17 cancer tissues and 17 nonmalignant tissues were examined by Real-time PCR.The effect of miR-100 overexpression on cell proliferation was examined by CCK-8 assay in vitro.Luciferase assay was used to confirm that miR-100 could directly target FGFR3.Real-time PCR and Western blot were used to examine the expression of FGFR3 in miR-100 overexpressing pancreatic cancer cells.The predicted target gene of miR-100,FGFR3,was downregulated by siRNA,and its effect on cell proliferation was also examined.Cell proliferation was analyzed using CCK-8 and Edu assay.Results miR-100 was lowly expressed in pancreatic cancer tissues (P ＜ 0.05).In pancreatic cancer cells,the transfection of lv-miR-100 was able to upregulate the endogenous expression of miR-100 and inhibit the cell proliferation (P ＜0.05).Luciferase assay showed FGFR3 was the direct target of miR-1O0.FGFR3 was significantly downregulated by overexpressing miR-100 in pancreatic cancer cells (P ＜0.05),and FGFR3 knockdown by specific siRNA exerted the similar effect as miR-100 overexpression (P ＜ 0.05).Conclusions Our study identified a new miRNA regulator,miR-100,and clarified a novel mechanism of how miR-100 regulates cell proliferation in pancreatic cancer.The strategy of overexpressing the tumor suppressor miR-100 may provide a new therapeutic approach for treating patients with pancreatic cancer.
