Objective To discuss the efficacy of fiberoptic ductoscopy(FDS)in the treatment of mammary duct diseases with nipple discharge.Methods Fiberoptic ductoscopy was utilized for diagnosing and treating exudative lesions in the mammary duct in 72 cases(80 sides).After the lesion was detected under ductoscope,repeated irrigation using normal saline was performed until the flocculent discharge disappeared.Intraductal drug administration(dexamethasone 5 mg and gentamycin 40 000 U)was given during the retreat of ductoscope.Results There were 57 sides of galactophoritis and 23 sides of mammary duct ectasia.A complete recovery was achieved in 65 sides(nipple discharge disappeared completely and no relapse occurred in 6 months),in which a follow-up for 1～2 years showed no recurrence.A remarkable improvement was obtained in 15 sides(nipple discharge significantly reduced,or progressively decreased within 6 months,or underwear wetted occasionally).Conclusions Fiberoptic ductoscopy in the treatment of mammary duct lesions with abnormal nipple discharge is effective.

Objective:To investigate the changes of occlusal plane in the process of retracting maxillary anterior teeth with different vertical traction force.Methods:The three dimensional finite element model of maxillary anterior teeth en-masse retraction by micro-implant was constructed with cone beam CT scanning and MIMICS and ANSYS software.Then the movement tendency of tooth and the changes of the maxillary occlusal plane was calculated when the vertical traction force was 0,0.5,0.75 and 1 N in the process of en-mass retraction,respectively.Results:Lingual tipping of anterior teeth,distal tipping of the first molar and the maxillary occlusal plane clockwise rotation by the retraction forces were observed.With the vertical traction force increasing,lingual tipping of anterior teeth and distal tipping of the first molar were decreased,and the occlusal plane clockwise rotation was prevented.Conclusion:The upper dentition movement and occlusal plane rotation can be changed effectively by the vertical traction with different force.When retract anterior teeth,0.5-0.75 N vertical traction force is beneficial to prevent clockwise rotation of the maxillary occlusal plane.

Objective To evaluate the effects of aminoguandine(AG) used as a selective inhibitor of the inducible isoform of nitric oxide synthase(iNOS) and L NAME used as a non selective inhibitor of nitric oxide synthase(NOS) on severe hemorrhagic shock Methods Forty rabbits were bled to mean arterial pressure of 4 4 66 kPa via femoral artery Hypotention was maintained for 120 min, the shed blood was then returned, followed by an infusion with Ringer′s solutions Animals were randomly divided into three groups: hemorrhagic shock group (n=14), AG group (AG 20mg/kg was infused intravenously ,n=14), L NAME group (L NAME 30mg/kg was infused intravenously with ,n=12) Plasma levels of endotoxin, tumor necrosis factor(TNF?) and nitric oxide (NO) were determined before and after shock, immediately after resuscitation and 0 5h, 2h, 4h after resuscitation The 24h and 48h survival rates were recorded Lung, intestine, liver and kidney tissues were obtained 48 h after shock for microscopic examination Results The plasma endotoxin, TNF? and NO levels markedly increased and were kept at high levels after shock Lower plasma levels of endotoxin TNF? and NO, less tissue damages and high survival rates were observed in AG group as compared with those in L NAME group and shock group Conclusions The endotoxin,TNF? and NO play an important role in the development of irreversible shock AG is beneficial in the treatment of hemorrhagic shock, while L NAME does not improve the outcome of shock

Ontology alignment technology is a knowledge engineering method to realize the concept and relationship integration of different ontologies.In view of the same scope of ontology,such as disease ontology,developed by researchers from a number of different areas or institutions of independent research and development,there is a big difference between the term expression and the concept of the relationship.Thus,how to achieve the integration of multi-source ontology through alignment processing has been recognized as a significant methodological problem.In this paper,the concept,technology,method and corresponding tool of ontology alignment were expounded at full length.The technique of ontology alignment based on linguistic features and structural features was emphasized.Combined with the two international disease ontology:Disease Ontology and Orphanet,the experiment and analysis of the technique of ontology alignment were carried out and detailed the application of alignment technology.Furthermore,for the existing multi-source problems on TCM ontology database,the necessity and application of ontology alignment were discussed.

Objective_To investigate the effect of estrogen(E2) on different age rat groups of Parkinson’s disease (PD) models induced by Rotenone and its mechanism.Methods_24-month-old SD rats(high age group)and 12-week-age SD rats( low age group ) were divided into control group ( saline ) , Rotenone treatment group ( Rotenone 2 mg/kg), Estrogen treatment group(Rotenone 2 mg/kg and E2 1 mg/kg)and Tamoxifen treatment group(Rote-none 2 mg/kg, E2 1 mg/kg and Tamoxifen 1 mg/kg).Behavior tests were carried out to observe the change of movement function, Immunohistochemistry and Western blot were used to assess the changes of TH and LC-3. HPLC-ECD was used to detect possible changes of monoamine neurotransmitters in striatum.Results_1) Rotenone reduced significantly old age rat’s rotarod latencies and prolonged the climbing pole time(P<0.05).E2 ameliorated this effect, Tamoxifen reduced the effect of E2.2) Rotenone significantly reduced the number of TH positive cells in
high age rats(P<0.05), E2 partly restored TH positive cell loss, Tamoxifen reduced this effect of E2, so did the ex-pression of TH protein.3)Rotenone increased the expression of LC-3(P<0.05), E2 did not affect the expression of LC-3, so did Tamoxifen.4)Rotenone significantly decreased the level of DA and its metabolite DOPAC(P<0.05), elevated the level of 5-HT especially in old rats(P<0.05).E2 downregulated the influence, and Tamoxifen reduced the effect of E2.5)Rotenone increased the number of autophagosomes, but E2 increased the proportion of autolyso-somes/autophagosomes.Conclusions_Old age rat PD model was more reliable.Estrogen promoted autophagy ma-ture, and had obvious therapeutic effect on rat PD model induced by rotenone.

Based on the Clinical Medical Research Information Sharing System ( CMRISS ) , this article took thedisease-syndrome-herb study on acute exacerbation of chronic obstructive pulmonary disease (AECOPD) as a model to explore the establishment of disease-syndrome-herb study method on many types of diseases for the guidance of Chinese medicine clinical practice. The CMRISS of the First Affiliated Hospital of Henan University of Traditional Chinese Medicine, which contained 5000 format electronic medical records from August 2011 to March 2013 , was used as the database . Data preprocessing , crystal reports and complex network were used in data mining to receive the frequency relation of AECOPD disease-syndrome-herb in order to analyze medica-tion features of different Chinese medicine clinical syndromes of AECOPD . The results showed that three syn-dromes, which were phlegm-heat obstructing the lungs, phlegm-stasis obstructing the lungs, and qi-yin deficien-cy, have corresponding Chinese herbs of licorice, orange peel and earthworm. The treatment of syndrome of phlegm-heat obstructing the lungs contains herbs to clear heat, remove phlegm and activate blood circulation. The treatment of syndrome of qi-yin deficiency contains herbs to benefitqi , nourish yin as well as to activate blood circulation and remove phlegm. It was concluded that the application of CMRISS is able to process a large amount of clinical data. The data mining results can be used to guide clinical practice. It provided a better plat-form for the scientific research of Chinese medicine clinical practice .
