To find a new method to identify Mori Cortex and its adulterants by analysis their ITS2 sequence of barcode,total genomic DNA was isolated from Mori Cortex and its adulterants. Nuclear DNA ITS2 sequences were amplified,and purified PCR products were sequenced. Sequence assembly and consensus sequence generation were performed using the CodonCode Aligner V3.0. The Kimura 2-Parameter (K2P) distances were calculated us-ing software MEGA 4.0. Identification analyses were performed using BLAST1, Nearest Distance and neighbor-joining (NJ) methods. The results showed the intra-specific genetic distance of Mori Cortex was 0, which were lower than inter-specific genetic distances between Mori Cortex and its closely related species (0.003-0.343). The ITS2 region is an efficient barcode for identification of Mori Cortex and its closely related species, which provides a scientific basis for fast and accurate identification and new method of Mori Cortex.

OBJECTIVE:
To investigate the efficacy and related factors of nasal surgery combined with upper air way radiofrequency ablation(RFA) for treatment of obstructive sleep apnea hypopnea syndrome (OSAHS) with chronic nasal blockage.
METHOD:
One hundred and three mild or moderate OSAHS patients with chronic nasal blockage were recruited, all cases had nasal surgery and upper airway RFA. All patients were evaluated by body mass index (BMI), Epworth sleep scale (ESS), snoring scale, and nocturnal polysomnography (PSG). Eighty-nine patients were reevaluated at least 6 months after surgery with the preoperative methods.
RESULT:
After operation, the apnea and hypopnea index (AHI) decreased from (18.67 +/- 9.48)/h to (9.22 +/- 7.18)/h; the lowest artery oxygen saturation (LSaO2) increased from (0.83 +/- 0.08) to (0.92 +/- 0.06); the Epworth sleep scale(ESS) decreased from (8.74 +/- 5.67) to (5.12 +/- 3.74); the snoring scale decreased from (7.16 +/- 2.85) to (3.56 +/- 2.26), the percentage of time with oxyhemoglobin saturation below 0.90 (CT90) decreased from (18.64 +/- 12.98) to (10.73 +/- 8.29). All of the differences were obvious (P<0.01). Success was defined as a postoperative apnea-hypopnea in dex < 10 events per hour and at least 50% less than the preoperative value. The surgical success rate was 75.3% (67/89). No major perioperative complications occurred.
CONCLUSION
Our findings suggest that nasal surgery combined with upper airway RFA can improve snoring and disease-specific quality of life in patients with anatomic na sal obstruction with mild or moderate OSAHS.

OBJECTIVE:
To observe the effect of tympanic injection of dexamethasone in the guinea pig endolymphatic hydrops and the change CFTR expression, to explore the effect of glucocorticoid treatment endolymphatic and its possible mechanism.
METHOD:
Thirty guinea pigs were divided into three groups: hormone group, water group, control group. The animals(hormone group, water group) in study were injected DDAVP 4 μg/kg in the first 7 d, and will increase to 6 μg/kg in the second 3 d. The control group was given normal saline, continuous 10 d. After twelfth days, the hormone group transtympanic injection of dexamethasone (5 mg/ml, 0.5 ml), and water group, control group transtympanic given normal saline (0.5 ml), continuous injection 5 d. Using immuno- histochemistry and Western blot to detect the cystic fibrosis transmembrane conductance regulator cochlear factor (CFTR) expression.
RESULT:
The water group ABR thresholds was significantly higher than that before the experiment (P < 0.01), and the water group was significantly higher than the rest of the groups (P < 0.01); Hormone group compared with the control group increased threshold value (P < 0.05). The control group had no endolym- phatic hydrops, the water group showed varying degrees of endolymphatic hydrops, cochlear duct and vestibular plus cochlear duct area ratio compared with the control group, hormone group was significantly higher (P < 0.01). hormone group area ratio was higher than the control group (P < 0.05). CFTR was primarily expressed in the stria vascularis, Corti's, spiral ligament, basilar membrane, cochlear ganglion,etc . The expression of CFTR in the water group was increased than that in the control group, and the hormone group (P < 0.01); the expression of hormone group increased compared with the control group (P < 0.05).
CONCLUSION
Tympanic injection of dexa- methasone can alleviate the desmopressin acetatein guinea pigs caused by membranous labyrinth, and the improve- ment of the hearing; Tympanic injection of dexamethasone can make the endolymphatic hydrops cochlea of guinea pigs decreased CFTR expression, indicating that the expression and possible mechanisms of CFTR intratympanic steroids reduce endolymphatic hydrops changes.

To improve 3-ketosteroid-△1-dehydrogenase (KSDH) activity and the transformation level for androst-4-ene-3,17-dione,3-ketosteroid-△1 -dehydrogenase gene (ksdD) from Arthrobacter simplex was cloned into plasmid pWB980 and expressed in B. subtilis WB600 under the control of promoter P43. The molecular weight of expressed enzyme was about 55kDa by SDS-PAGE analysis. The activitities assayed by spectrophotometrical method of intracellular and extracellular soluble enzyme were 110 ± 0.5mU and 15 ± 0.6mU per milligram of protein respectively. The transformation rate of androst-4-ene-3,17-dione by the B. subtilis recombinant cells was 45.3%. Compared with Arthrobacter simplex, the enzyme activity of KSDH expressed in B. subtilis was improved about 30 fold, and the transformation level of androst-4-ene-3,17-dione by the B.subtilis recombinant cells was improved about 10 fold. The recombinant B. subtilis cells used in biotransformation of steroids provided a new way for steroid medicines production.

Objective To analyze the onset time rule of spontaneous pneumothorax ,and investigate the influence of climatic factors such as atmo-spheric pressure,wind speed,etc. on the onset of spontaneous pneumothorax. Methods Five hundred and ninety-three patients of spontaneous pneumothorax in Cenral Hospital Affiliated to Shenyang Medical College were enrolled for this study between January 1,2011 and December 31, 2015. The data of the average daily atmosphere pressure and wind speed in five years were recorded. The relationship between the onset of sponta-neous pneumothorax and the change of the atmosphere pressure and wind speed was analyzed. Results The incidence of spontaneous pneumotho-rax in Shenyang area was obvious seasonal. Primary spontaneous pneumothorax episodes were observed mostly in spring and in March and April;Second spontaneous pneumothorax episodes were observed mostly in winter and in November and December. The difference in mean atmospheric pressure was 0.6 hPa lower than on days in which no spontaneous pneumothorax occurred. This difference was statistically significant(P=0.015). We observed significantly higher average wind speed on days with SP versus days without(9.46±6.33 m/s vs 7.11±5.47 m/s,P<0.001). Conclu-sion Spontaneous pneumothorax has obvious aggregation of onset time. A sharp drop in atmospheric pressure and increases in wind speed has im-portant influence on the incidence of spontaneous pneumothorax.
