Localizing the anterior wall of the maxillary sinus and maxillary tuberosity using Auto-CAD software / 中国组织工程研究

BACKGROUND:To make a better preparation for orthodontic tooth, we investigate the changes in the localization of the anterior wal of the maxilary sinus and maxilary tuberosity, analyze the development of the maxila, and detect the bone mass of the maxila and development timing. However, the use of Auto-CAD software has not been reported to localize the anterior wal of the maxilary sinus and maxilary tuberosity. OBJECTIVE: To investigate the localization and growth of the anterior wal of the maxilary sinus and maxilary tuberosity in 300 children aged 4-14 years from the Han ethic group in Urumqi, Xinjiang Uygur Autonomous Region, China. METHODS: Totaly 300 children, 4-14 years of age, admitted at the Stomatological Hospital of Urumqi, Xinjiang Uygur Autonomous Region, China, were enroled. According to Helman’s dental developmental staging, these children were divided into five groups: groups IIA, IIC, IIIA, IIIB, IIIC. Auto-CAD software was used to analyze the panoramic radiographs of the maxila and mandible. The tracing of each radiograph was digitized by translating the reference points onto an X-Y coordinate system. The straight line that passed the point where the nasal septum intersected with the hard palate (point O) and the point where the medial wal of maxilary sinus intersected with the hard palate (point PA) was designated as the X axis. The straight line that was vertical to the X axis and passed through the point O at a right angle was designated as the Y axis. The X and Y coordinate values of reference point were calculated. And then O point was set as (0, 0), and the point where the posterior wal of maxilary tuberosity intersected with the hard palate (PP) was set as (PPX, PPY). Colected data were analyzed statisticaly to understand the changes in the localization of PA and PP at different stages of dental development. RESULTS AND CONCLUSION:The change of point PA had on significant differences between the five groups (α > 0.05). Point PP grew obviously in a horizontal rearward and vertical downward manner from stage IIA to IIIA; this point only presented a horizontal rearward growth from stage IIIA to IIIB and only a vertical downward growth from stage IIIB to IIIC. This period was the time of the second molar eruption, indicating that the second molar eruption is helpful to the vertical growth of the maxila.

Characteristics of angiographically confirmed drug-eluting stent thrombosis / 中华老年医学杂志

Objective To analyze the clinical characteristics and outcomes of angiographically confirmed drug-eluting stent thrombosis (ST). Methods All the angiographically confirmed ST was enrolled in the study from March 2005 to March 2009. Clinical data, angiographic outcomes, procedures of PCI, and anti-platelet treatment of ST were retrospectively collected. Results Total 20 cases of ST included 18 cases (90.0%) of sirolimus and derives eluting stents and 2 cases (10.0%) of paclitaxel eluting stent. Ten (50.0%) stent thromboses were subacute, 1 (5.0%) were late, and 9 (45.0%) were very late. ST reoccurred in 3 cases and occurred simultaneously in two arteries in 1 case. All the cases presented with ST-segment elevation myocardial infarction (STEMI). ST occurred in 16 cases after emergency PCI and 4 cases after selective PCI. Nine late stent thrombosis occurred after clopidogrel cessation. Long stents (stent length ≥ 30 mm) were implanted in 12 cases (60.0%), of which overlap stents were implanted in 8 cases (40.0%).Balloon angioplasty was used in 16 cases (80.0%). The 2 patients died from STEMI during hospitalization and 1 patient accepted coronary artery bypass graft for repetitive ST. Conclusions Angiographically confirmed ST appears rarely, but most frequent ST presents with STEMI. ST is related with long stent implantation and emergency PCI. Balloon angioplasty is frequently used for ST. Some patients have the risk of multiple arteries and repetitive ST.

Objective To investigate the long-term anticoagulation starus and relation of INR and complica-tion,best anticoagulation range and clinical significance in patients after mechanical heart valve replacement. Meth-ods The data of blood clotting test series(containing PT,PT% ,PTR,INR,Fbg,APTT) for patients after 6 months of mechanical heart valve replacement were collected, then the cases were divided into 4 groups according to their INR levels( group Ⅰ : INR < 1.5; group Ⅱ : INR 1.5 ～ 2.0 ; group Ⅲ : INR 2.1 ～ 2.5 ; group Ⅳ : INR > 2.5 ). Results Group Ⅰ contained 28 person-times, with their dosage of warfarin for (3.61 ± 1.44 ) mg, INR 1.38 ± 0. 12, core-bral embolism occurred for 4 person-times,with a inception rate of 14%. Group Ⅱ contained 92 person-times,with their dosage of warfarin for (3.5±1.37)mg,INR 1.65±0. 14,hemorrhinia occurred for 2 person-times,with a in-ception rate of 2%. Group Ⅲ contained 80 person-times, with their dosage of warfarin for (3.18±1.63 )mg, INR 2.23±0.19 ,bematuria occurred for 2 person-times, bemorrhinia occurred for 2 person-times, with a total inception rate of 5% ; Group Ⅳ contained 16 person-times, with their dosage of warfarin for ( 2.32 ± 1. 23 ) mg, INR 2.80± 0.19, hemorrhinia occurred for 2 person-times and hemoptysis occurred for 1 person-times, with a total inception rate of 18.7%. The person-times in group Ⅱ and Ⅲ accounted for 79.6% and the complication rate was the lowest when INR was between 1.5-2.5. Conclusions INR levels between 1.5-2.5 is the most secure, which is the best antico-agu]ation range in our region. Since the anticoagulation strength dynamically changes, the long-term anticoagulation status in patients after mechanical heart valve replacement should be deeply concerned.
