Abstract Background: Orthodontic temporary anchorage devices (TADs) offer absolute anchorage for clinical orthodontics. No systematic course on TADs has been described so far. The objectives of this study were to develop a systematic course on orthodontic TADs and to determine its teaching outcome.Methods: Five modules (fundamentals, anatomic sites, clinical applications, complications and insertion techniques, FACCI) were designed in this FACCI course on TADs. A total of 61 orthodontic graduate students from Department of Orthodontics, West China Hospital of Stomatology, Sichuan University were enrolled in this study. Baseline levels on the use of TADs were surveyed through a before-course questionnaire and the teaching outcomes were assessed through an after-course questionnaire.Results: After the course, significantly more students were willing to insert TADs by themselves (p<0.001). Students were significantly more familiar with the clinical applications of TADs for different types of tooth movements (p<0.001) and the insertion techniques of TADs at different anatomic sites (p<0.001). Before the course, most of the students had no knowledge on addressing TADs-associated complication and they were significantly more familiar with the techniques and skills of addressing TADs-associated complication after the course (p<0.001).Conclusions: The FACCI course on orthodontic TADs was effective and promoted the clinical applications of TADs in clinical practice among orthodontic graduate students.

Одним из основных требований к разработке экспериментальных моделей цереброваскулярных заболеваний является их максимальная приближенность к реальной клинической практике. В работе систематизированы данные по основным методам моделирования острой ишемии головного мозга (ОИГМ), представлена их классификация, анализируются данные о преимуществах и недостатках той или иной модели. Обсуждаются результаты экспериментальных исследований по изучению патогенеза ОИГМ с использованием различных моделей (полной и неполной глобальной, локальной и мультифокальной ишемии) и способов их реализации (перевязка артерий, клипирование, коагуляция, эмболизация и др.). Особое внимание уделяется «стабильности» последствий острого нарушения мозгового кровообращения: необратимых ишемических повреждений головного мозга или обратимых с реперфузией заданной продолжительности. Отмечается, что важное значение в этих исследованиях должно принадлежать современным методам прижизненной визуализации очагов острого ишемического повреждения, что позволяет оценивать динамику патологического процесса. Предлагаемый метод отвечает требованиям гуманного обращения с животными. Подчеркивается, что выбор релевантной модели ОИГМ определяется задачами предстоящего исследования и технологическими ресурсами научной лаборатории. Development of experimental models for acute forms of cerebrovascular diseases is essential for implementation of methods for their prevention and treatment. One of the principal requirements to such models is their maximum approximation to actual clinical practice. This review systematized major models of acute cerebral ischemia (ACI), their classification, and presented information about their advantages and shortcomings. Also, the review presented results of experimental studies on pathophysiological mechanisms of different types of modeled ACI (complete and incomplete global, local, and multifocal ischemia) and methods for creating these models (arterial ligation, clipping, coagulation, embolization, etc.). Particular attention was paid to “stability” of the consequences of acutely impaired cerebral circulation - an irreversible ischemic brain injury or a reversible injury with reperfusion of a given duration. The authors emphasized that in such studies, a special significance should be given to intravital imaging of acute ischemic damage foci using modern methods, which allow assessing the dynamics of the pathological process and meet the requirements to humane treatment of animals. The choice of a relevant ACI model is determined by objectives of the planned study and the technological resources available at the research laboratory.

Background: The incoming disease-modifying therapies against Alzheimer’s disease (AD) require reliable diagnostic markers to correctly enroll patients all over the world. CSF AD biomarkers, namely amyloid-β 42 (Aβ42), total tau (t-tau), and tau phosphorylated at threonine 181 (p-tau181), showed good diagnostic accuracy in detecting AD pathology, but their real usefulness in daily clinical practice is still a matter of debate. Therefore, further validation in complex clinical settings, that is patients with different types of dementia, is needed to uphold their future worldwide adoption. Methods: We measured CSF AD biomarkers’ concentrations in a sample of 526 patients with a clinical diagnosis of dementia (277 with AD and 249 with Other Type of Dementia, OTD). Brain FDG-PET was also considered in a subsample of 54 patients with a mismatch between the clinical diagnosis and the CSF findings. Results: A p-tau181/Aβ42 ratio higher than 0.13 showed the best diagnostic performance in differentiating AD from OTD (86% accuracy index, 74% sensitivity, 81% specificity). In cases with a mismatch between clinical diagnosis and CSF findings, brain FDG-PET partially agreed with the p-tau181/Aβ42 ratio, thus determining an increase in CSF accuracy. Conclusions: The p-tau181/Aβ42 ratio alone might reliably detect AD pathology in heterogeneous samples of patients suffering from different types of dementia. It might constitute a simple, cost-effective and reproducible in vivo proxy of AD suitable to be adopted worldwide not only in daily clinical practice but also in future experimental trials, to avoid the enrolment of misdiagnosed AD patients.

UNSTRUCTURED The COVID-19 pandemic spurred unprecedented progress on a paradigm shift to telemedicine to limit exposure to the virus. Telemedicine has many benefits. In the West China Hospital of Sichuan University, we use it to do COVID-19 related tele-educations to health professionals and general population, tele-diagnosis, online treatment and internet-based drug prescription and delivery. However, at our practices, we are noticing that many older adults could not make appointment with doctors due to their difficulty using the internet-based platform. We worried that older adults who need healthcare the most are not well prepared for this rapid change. We need to pay attention to avoid causing treatment disparities for vulnerable older adults 60 years of age and over. Researchers and policy makers should work together to study effective strategies and make proper policies to mitigate barriers older adults face when using telemedicine.

Abstract Background Using effective scolicidal agents intraoperatively is essential to lessen the recurrence rate of hepatic echinococcosis. However, severe hypernatremia may occur after hypertonic saline (HS) has been applied as the scolicidal agent. The aim of this study is to report on pediatric patients with severe hypernatremia after hepatic echinococcus surgery. Methods Patients who presented to West China Hospital between January 2010 and February 2017 were retrospectively analyzed. Children under 16 years with echinococcosis treated by resection were included in the study. Results A total of 26 children were enrolled in this study, including 16 boys and 10 girls with a median age of 8 (2–16). 24 (92.3 %) cases were cystic echinococcosis (CE) and two (7.7 %) were alveolar echinococcosis (AE). According to Clavien-Dindo classification of surgical complications, the complication rate of all 26 patients was 19.2 %, among which three cases belonged to Grade I, one to Grade III b and 1 to Grade IV. Two children encountered severe hypernatremia (sodium: 155.3 mmol/L and 190.0mmol/L). Data showed classic clinical features of severe hypernatremia: profound and persistent bradycardia, hypotension and coma. After treatment, they recovered well without any neurologic sequelae. All patients were followed up regularly for a median time of 38 months (range 4–89 months); the overall disease-free survival was 100.0 %. Conclusions HS irrigation of intra-abdominal echinococcosis may cause acute hypernatremia and severe consequences. Diagnostic suspicion and early intervention are vital tools for avoiding morbidity and mortality.

Abstract Background The genus Arisaema (Areaceae), popularly known as cobra lilies and jack in pulpit is mainly found in temperate to tropical areas of all continents except South America, Europe and Australia and contain about more than 250 species. Arisaema genus is being used by the different folks of human populations for medicinal as well as food purposes. Arisaema plants are used for the treatment of different types of diseases. There have been several attempts to highlight different aspects of genus Arisaema by describing it in terms of phytochemistry and medicinal uses. The present study is, however, an attempt to put together all the former data available related to the phytochemistry and medicinal uses of genus Arisaema. Main body The phytochemicals of the plant include alkaloids, phenols, terpenes, flavonoids, lectins, saponins, glycosides, triterpenoids, stigmasterols, n-alkanes, n-alkanols sitosterols, campesterol, oxalates, coumarins, tannins etc. Moreover, the properties such as antioxidant, antifungal, antibacterial, insecticidal, antimicrobial, cytotoxic, nematocidal, antiallergic antitumour and anticancer activities are also shown by the plants belonging to genus Arisaema. Arisaema plants have been traditionally used to treat various ailments such as resolving phlegm, dampness, and to treat asthma, bronchitis, cold, cough, and laryngitis etc. It has been found that there are several species which are toxic by nature. The development of clinical applications of arisaematis rhizomes had been seriously constrained due to its toxic properties like, mouth and lingua pain, even respiration slowing and suffocation, mucous membrane and skin irritation etc. and this toxicity of arisaematis rhizomes is due to raphide components. Conclusions The collection of data available on the phytochemistry of genus Arisaema is not sufficient as further work is required to do on phytochemical and medicinal basis. The data available on phytochemistry and medicinal properties of the plants belonging to genus Arisaema throws light on various species of Arisaema which are medicinally important and have been exploited to treat different types of diseases in the world.

Therapeutic Profile

Background: Pinus and other related conifers belonging to family pinaceae are most commonly used medicinal plants in Indian North-western Himalayas. Various parts of these plants including needles are source of several well known alkaloids. Of all the alkaloids, piperidine group is one of important component and hold considerable medicinal importance. Methods: The group of alkaloids was initially identified from genus Piper through which a large variety of piperidine molecules have been extracted. The planar structure of this heterocyclic nucleus enables acetamide groups to be added at various ring configurations. Results: In the area of drug research, the piperidine heterocycle has gained considerable interest. To produce a new therapeutic profile, the broad range of its therapeutic application paved the way for researchers to implant the nucleus from time to time in diversified pharmacophores. Discussion: However, biological functions of piperidine metabolites have been mostly examined on a limited scale and that most of the findings are thus preliminary. We have tried to present different clinical applications of piperidine alkaloids in this study that researchers have already attempted to demystify from time to time. Conclusion: Given the importance of the piperidine nucleus, the study will enable the researcher to produce scaffolds of the highest therapeutic efficacy. We have also illustrated different types of piperidine, its sources in different member of family pinaceae with special emphasis on Pinus.
