Patent ductus arteriosus (PDA) is a frequent congenital heart disease .Incidence rate of PDA accounts for 10% ~21% of total incidence rate of congenital heart disease .In recent years ,along with the continuous deepening understanding of anatomical structure and pathology of PDA ,there were a variety of treatment methods ,including drug therapy ,interventional therapy and operation .The present article made a review about indications ,contraindi‐cations ,advantages and disadvantages of above three treatments .

Objective To study the effect of different palatal vault shape on the stress distribution of edentulous maxilla surface.Methods Using three-dimensional finite element method(3-D FED),we simulated five bite states,putting five loading conditions on 3-D FED model of maxillary edentulous with three different palatal vault shapes.Results We obtained the stress value and multicolor picture of 3-D FE model.Labial frenal notch zone and alveolar ridge zone were the stress concentration zone of the maxillary edentulous with three different palatal vault shapes under five kinds of loading conditions.The deep palatal vault maxillary edentulous almost had the maximum stress values in labial frenal notch zone,palate zone and alveolar ridge zone,and upper edentulous jaw with palatal torus was the minimum.Conclusion Palatal vault shape can change the stress value of edentulous maxilla surface,but cannot change the stress distribution.Loading condition can change the stress distribution and stress value.

Objective To investigate the MRI features of urethral sphincter in female with stress urinary incontinence(SUI) by the study of the indexes of the thickness of middle urethral sphincter, the function urethral length and bladder neck funnel . Methods Forty patients of female patients diagnosed as SUI by clinical were retrospectively as SUI group, and 40 asymptomatic female volunteers were recruited as reference group. All of the subjects were tested by pelvic MRI scanning both in static status and in the condition of Valsalva. The thickness of middle urinary sphincter was measured in the horizontal axis plane. In the midsagittal plane, the function urethral length was measured from the internal orifice to perineal fascia. The bladder neck funnel whether exist was observed from the midsagittal plane. For the comparison of the urinary sphincter thickness and urethral length of the two groups, independent sample t test was adopted. For urethral length in static status and under the condition of Valsalva, paired t test was done. For comparison of positive rate of the bladder neck funnel, Chi?squared test has been done. Results The value of the middle urinary sphincter thickness in the groups of SUI and reference were (2.23±0.68) mm and (2.69± 0.75) mm, respectively. Thus the differences of the two groups had statistical significance (t=-2.839, P<0.01 ). In the static status, the urethral length in SUI and reference group were (2.72±0.51) cm and (2.94± 0.34) cm respectively, wheras in Valsalva condition, the value were (2.33 ± 0.49) cm and (2.43 ± 0.43) cm respectively. The differences of the two groups had statistical significance in static status (t=-2.322, P=0.023), wheras there had no statistical significance in the two groups in Valsalva condition (t=-1.049,P=0.297). For SUI and reference group, both in static status and Valsalva condition, the difference of function urethral length had statistical significance (P< 0.01). The positive rate of bladder neck funnel for SUI was 72.5% (29/40), and for reference was 22.5% (9/40), the difference of the two groups had statistical significance(χ2=20.050, P<0.01). Conclusion For female SUI patients, urinary sphincter muscle is much thinner, function urethral length is much shorter and has higher positive rate of bladder neck funnel.

Objective To investigate the dynamic changes in each radical line of pelvic floor levator hiatus in female with stress urinary incontinence(SUI). Methods A retrospective analysis of MR images was performed in 30 female patients with clinically diagnosed SUI and 30 asymptomatic female volunteers recruited as reference group. All of the subjects underwent pelvic MRI scanning both in static statusand Valsalva maneuver, respectively, Valsalva was performed by attempt to forcibly urinate while holding her breath, respectively. Area of pelvic diaphragm hiatus (LHA), ntero-posterior length (LHL) and tmixmum width (LHW) were measured in horizontal axis plane of the obtained images.H line distance was measured in the midsagittal plane. Independent sample t test was performed to compare the difference in LHA, LHL and LHW between two groups. Paired t test was used to compare difference in LHA, LHL and LHW between two groups in static status and Valsalva maneuver, respectively. Results In static status, the values in LHA, LHL, LHW and H line distance for SUI groups were(28.7±19.3) cm2, (7.1±2.2) cm, (4.7± 1.6 ) cm and (5.7±1.1) cm, respectively. The parameters for the reference group were(13.1±3.7)cm2, (5.3± 0.8) cm, (3.4 ± 0.5) cm and (5.7 ± 0.9) cm, respectively. The difference in LHA, LHL, LHW between two groups was statistically significant (t=4.33, 4.36, 4.23, and P<0.01 for all indexes), whereas the difference in H line distance between two groups was no statistically significanct because of P> 0.05. In Valsalva
maneuver, LHA, LHL, LHW and H line distance were (40.0±26.0) cm2, (8.0±2.3) cm, (6.0±2.5) cm and (6.1± 1.5)cm for SUI group, and were (16.2±6.2) cm2,(5.5±1.0) cm, (3.6±0.8) cm and (6.0±1.0) cm for the reference group, respectively. The difference in LHA, LHL and LHW between two groups was statistically significant, (t=4.88, 5.36, 4.91 respectively, and P<0.01), whereas the differencein H value between two groups was no statistically significant (P< 0.05). For SUI group , the difference of LHA, LHL and LHW between static status and Valsalva maneuver had statistically significant with P<0.01. For reference group, the difference of LHA and LHL between static status and Valsalva maneuver had statistically significant(P<0.05). Conclusion Dynamic and static pelvic MRI can evaluate the morphology and variation of pelvic floor levator hiatus much intuitively and accurately. pelvic floor levator hiatus becomes enlarged in female with SUI.

The signal transduction system induced by epidermal growth factor receptor(EGFR) regulates cell cycle ,modulates cell growth and differentiation and improves damage repair.The overexpression of EGFR in several epithelial tumors including non small cell lung cancer(NSCLC) forecasts low survival rate, poor prognosis and metastasis. Thereby EGFR can be a potential target for gene therapy. Tyrosine kinase inhibitors(TKIs) selectively inhibit tyrosine kinase activity,supress tumor growth ,and increase the sensitivity of radio chemotherapy. [

BACKGROUND:With the development of science and technology and improvement in living quality, telemedicine has played an important role in daily life, in particular in disease diagnosis and treatment as wel as rescue process for elderly people. OBJECTIVE: Based on Web of Science and ClinicalTrials.gov databases, to analyze the international telemedicine and elderly disease development so as to provide referential basis for the related study in China. METHODS: An online retrieval of Web of Science and ClinicalTrials.gov databases was performed with the key words “telemedicine” and “geriatric diseases” for papers regarding telemedicine for geriatric diseases published from 2003 to 2013. RESULTS AND CONCLUSION: (1) 239 papers regarding telemedicine for geriatric diseases were retrieved in Web of Science from 2003 to 2013. As per distribution by country for publications, USA published the highest number of papers (n=93, 38.912%). As per distribution by institute for publications (2003-2013), University of Washington was most prolific, folowed by Columbia University, The University of Queensland and The University of Western Australia (Australia). Among the included journals,Journal of Telemedicine and Telecare published the greatest number of papers (n=20, 8.368%). The number of included papers gradualy increased over the 10-year study period. Among these 239 papers, only 4 of them were from China, indicating that Chinese scholars paid relatively little attention in this research field, and the number and quality of Chinese papers on telemedicine for geriatric diseases need to be improved. (2) 18 studies regarding telemedicine for geriatric diseases were registered in ClinicalTrials.gov database from 2003 to 2013. Interventional studies (n=15) accounted for the largest proportion, folowed by observational studies.
