AIM：To examine the effects of patient age,canalicular obstruction,mode of anesthesia,and duration of nasolacrimal intubation on the outcomes of endoscopic endonasal dacryocystorhinostomy（DCR）. METHODS： Totally 56 eyes of 46 patients with prolonged epiphora underwent minimally invasive endoscopic endonasal DCR.A successful surgical outcome was defined as a significant improvement in symptoms,adequate water passage from the puncta to the nasal cavity,and patency of the DCR *** outcomes were assessed at least 6mo after ***＇s exact test was used to discuss the factors,and then the logistic regression analysis was made by SAS9.4 ***： The overall success rate was 75.0%,and complete resolution was observed in 27 *** success rate was higher for patients with ≥6mo intubation than for those with 〈6mo ***,there were no significant differences in outcomes between groups stratified by age（〈65 or ≥65y）,presence or absence of canalicular obstruction,mode of anesthesia（local or general）,and use or nonuse of a radiowave *** patient developed subcutaneous emphysema around the eye and nose and one developed subcutaneous hemorrhage after surgery. CONCLUSION： Endoscopic endonasal DCR can be considered safe and minimally invasive with reasonable success rates,particularly when the duration of nasolacrimal intubation is ≥6mo.

Background: Implementing invasive procedures is an important part of patient management by clinical nurses;however, there are gaps between nurses’ actual knowledge and skills and expected professional care capacity. Purpose: This scoping review aimed to map the existing literature related to recent institution-provided educational programs for invasive procedures involving clinical nurses. This study seeks to understand the contents of educational programs and the methods for assessing educational effects. Methods: This scoping review was completed using the following four databases: PubMed (MEDLINE), Embase, Cochrane Library, and Emcare for the period 2000-2022. We included studies that used all forms of educational approaches (e.g., didactic lectures, hands-on training, or on-the-job training). This scoping review considered peer-reviewed publications published in English using quantitative, qualitative, or mixed approaches. A total of 83 studies underwent in the final analysis. Results and Conclusion: A combination of didactic lectures and hands-on training was provided as an educational program in most studies. Contrary to our prediction, educational interventions with advanced technologies such as VR are extremely rare, suggesting that the effectiveness of advanced technologies in learning invasive procedures should be examined to facilitate and retain educational effects more efficiently in future studies. Regarding the assessment of educational effects, nurses’ cognitive (i.e., theoretical knowledge about procedures), psychomotor (i.e., implementing procedures), and psychological aspects (e.g., confidence and self-efficacy in procedures) were evaluated using questionnaires and observational methods. While most studies used a one-group pretest-posttest design, the ratio of randomized controlled trials (RCT) was relatively low. Thus, an RCT design should be introduced in future studies to test the validity of the developed educational program more accurately.

The rare earth manganite BaLn2Mn2O7(Ln = rare earth element) has a Sr3Ti2O7-type layered perovskite structure with double-block oxygen octahedra belonging to the Ruddlesden-Popper-type homologous series AO(ABO3)2. In Pr-manganite, a novel phase transition was first observed in situ at 1040 K by a thermal transmission electron microscope. At 1040 K, reflections began to split along the c-direction in the selected area diffraction pattern. This indicates that a new phase appears in the original phase matrix; the c length of the new phase is 1.5% longer than that of the original phase. After about 5 min, the original phase disappears. No change in the crystal symmetry (space group 14/mmm) is observed above 1040 K.

The titled high performance foamed concrete was developed from Portland cement, ultra fine granulated blast-furnace slag, pulverized fly ash and condensed silica fume by means of pre-foaming process. The resultant foamed concrete presents its thermal conductivity of about 0.16-0.75 W/（m·℃） and 28 d compressive strength of about 1.1-23.7 MPa when its mix proportion varies in the range of cement content 280 kg-650 kg/m^3, fly ash 42-97 kg/m^3, slag 64-146 kg/m^3, silica fume 34-78 kg/m^3, and sand 0-920 kg/m^3. The compressive strength of the foamed concrete with oven dried bulk density of 1500 kg/m^3 in appropriate mix proportion and with small amount of superplasticizer reached as high as 44.1 MPa. Meanwhile, the flesh foamed concrete behaves like an excellent flow-ability, therefore, is especially suitable for the application in case of massive foamed concrete casting in situ and in the case of filling casting into large volume underground irregular voids, except for pre-casting of building components like blocks, bricks, and wall panels.
