Research progress on dental materials for preventing root caries / 口腔疾病防治

@#The high incidence and untreated rate of root caries, a common and frequently occurring oral disease with challenging treatment in elderly individuals, is the main cause of tooth loss among elderly people, as rapid development results in pulpitis and periapical periodontitis or residual crown and root, which has been regarded as one of the common chronic oral diseases seriously affecting the quality of life of elderly people. Thus, early intervention and prevention are important. Traditional dental materials for preventing root caries have been widely used in clinical practice; however, they have the disadvantages of tooth coloring, remineralization and low sterilization efficiency. A series of new dental materials for preventing root caries have gradually become a research hotspot recently, which have the advantages of promoting the mineralization of deep dental tissue, prolonging the action time and enhancing adhesion. Future caries prevention materials should be designed according to the characteristics of root surface caries and the application population and should be developed toward simplicity, high efficiency and low toxicity. This review describes current research regarding anti-caries prevention material application, serving as a theoretical underpinning for the research of root caries prevention materials, which is important for both promotion in the effective prevention of root caries and improvement in the status of oral health and the quality of life among old people.

Staging Sequential Treatment of Ischemic Stroke Based on Syndrome Differentiation of Deficiency and Excess in Eight Principles / 中国实验方剂学杂志

The core of diagnosing and treating diseases in traditional Chinese medicine lies in syndrome differentiation. The eight principles of syndrome differentiation serve as guidance for syndrome differentiation. As one of the eight principles of syndrome differentiation， the differentiation of deficiency and excess is the basic and critical method. Ischemic stroke is currently the leading cause harming the health of Chinese residents. Although the hypotheses about the cause of ischemic stroke have evolved from external wind to the later internal wind and to the modern theory of toxin damaging the brain collaterals， they all believe that this disease is rooted in internal deficiency and external excess. According to available studies， although stroke is characterized by complex pathogenesis and rapid progression of syndromes， the key cause evolution has a regularity， that is， from excess to deficiency. This article analyzes the historical evolution of the etiology， pathogenesis， and syndrome differentiation schemes of stroke. There are diverse schemes for the syndrome differentiation of stroke， which make it difficult to choose in clinical practice. In view of this problem， this paper puts forward a new approach of staging sequential treatment of ischemic stroke based on the differentiation of deficiency and excess according to the evolution law of the key cause of stroke. Furthermore， we conducted a randomized controlled study on 100 patients with ischemic stroke to evaluate this new approach. The results showed that the staging sequential treatment of ischemic stroke based on the differentiation of deficiency and excess demonstrated definite clinical efficacy. In addition， this article reviews the previous research results of our team and the research achievements of other teams to preliminarily explore the relationship between stroke syndromes and biomarkers， aiming to provide an objective basis for unveiling the pathogenesis of stroke. In summary， according to the key cause evolution （from excess to deficiency）， the treatment of ischemic stroke by stages based on differentiation of deficiency and excess can facilitate the rapid intervention and improve the clinical efficacy on ischemic stroke.

Assessment of the learning curve of peribulbar blocks using the Learning-Curve Cumulative Sum Method (LC-CUSUM): an observational study

Abstract Introduction: This study aimed to assess the learning curves of peribulbar anesthesia and estimate the number of blocks needed to attain proficiency. Methods: Anonymized records of sequential peribulbar blocks performed by first-year anesthesia residents were analyzed. The block sequential number and the outcomes were extracted from each record. Success was defined as a complete sensory and motor block of the eye, and failure was defined as an incomplete block requiring supplemental local anesthetic injections or general anesthesia. Learning curves using the LC-CUSUM method were constructed, aiming for acceptable and unacceptable failure rates of 10% and 20%, and 10% probability of type I and II errors. Simulations were used to determine the proficiency limit h0. Residents whose curves reached h0 were considered proficient. The Sequential Probability Ratio Test Cumulative Sum Method (SPRT-CUSUM) was used for follow-up. Results: Thirty-nine residents performed 2076 blocks (median = 52 blocks per resident; Interquartile Range (IQR) [range] = 27-78 [4-132]). Thirty residents (77%) achieved proficiency after a median of 13 blocks (13-24 [13-24]). Conclusions: The LC-CUSUM is a robust method for detecting resident proficiency at peribulbar anesthesia, defined as success rates exceeding 90%. Accordingly, 13 to 24 supervised double-injection peribulbar blocks are needed to attain competence at peribulbar anesthesia.

A way forward in pulmonary aspiration incidence reduction: ultrasound, mathematics, and worldwide data collection

Abstract Aspiration of gastric contents during induction of general anesthesia remains a significant cause of mortality and morbidity in anesthesia. Recent data show that pulmonary aspiration still accounts for many cases with implications on mortality despite technical and technological evolution. Practical, ethical, and methodological issues prevent high-quality research in the setting of aspiration and rapid sequence induction/intubation, and significant controversy is ongoing. Patients' position, drugs choice, dosing and timing, use of cricoid force, and a reliable risk assessment are widely debated with significant questions still unanswered. We focus our discussion on three approaches to promote a better understanding of rapid sequence induction/intubation and airway management decision-making. Firstly, we review how we can use qualitative and quantitative assessment of fasting status and gastric content with the point-of-care ultrasound as an integral part of preoperative evaluation and planning. Secondly, we propose using imaging-based mathematical models to study different patient positions and aspiration mechanisms, including identifying aspiration triggers. Thirdly, we promote the development of a global data collection system aiming to obtain precise epidemiological data. Therefore, we fill the gap between evidence-based medicine and experts' opinion through easily accessible and diffused computer-based databases. A better understanding of aspiration epidemiology obtained through focused global data gathering systems, the widespread use of ultrasound-based prandial status evaluation, and development of advanced mathematical models might potentially guide safer airway management decision making in the 21st century.

A discussion on the tactics for cultivating medical students' autonomous learning ability / 中华医学教育探索杂志

This article analyzes the limitations of traditional medical theory teaching, and proposes the strategies for cultivating medical students' autonomous learning ability, i.e., informatization-based flipped classroom, problem-oriented teaching, mind mapping training, semi-open book examination, exploitation of the clinical and scientific thinking, and practice activities of medical humanities. The strategies of "problem oriented teaching" and "mind mapping training" were integrated into the practice teaching of hematology. Compared with the traditional medical teaching mode, students' feedback after class showed that the teaching mode incorporating new cultivation strategies was more conducive to the improvement of students' self-learning ability ( P = 0.008), and their satisfaction with teaching mode, learning interest, and self-learning ability were all improved. Thus, the appropriate application of the above strategies can help improve students' autonomous learning ability and optimize the effect of medical theory teaching.

Thoughts of syndrome differentiation and treatment of precancerous lesions of chronic atrophic gastritis based on the theory on hidden pathogen / 国际中医中药杂志

Precancerous lesions of gastric cancer (PLGC) is a pathological change accompanied by intestinal metaplasia and dysplasia on the basis of chronic atrophic gastritis. It is also an important stage of "inflammation-cancer transformation" on gastric mucosa. Paying attention to the intervention of PLGC has important value and significance for the secondary prevention of gastric cancer. PLGC has the characteristics of occult onset, toxin damaging collaterals, and long course of disease, which is highly consistent to the pathogenesis characteristics of incubative pathogenic factors. Based on the relevance of incubative pathogenic factors and PLGC, treatment of PLGC from the perspective of incubative pathogenic factors should be mainly strengthening the spleen and stomach, and combined with the methods of regulating qi and dissipating dampness, and removing blood stasis and detoxification. It should also pay attention to the prognosis.Paying attention to the body-mind treatment can reduce the re-occurrence , so as to provide a new way of thinking for treating PLGC from incubative pathogenic factors.

L-glutamine supplementation reduced morphological damage in the renal glomerulus of rats with Walker-256 tumor

ABSTRACT Purpose: To evaluate the effects of the experimental subcutaneous Walker-256 tumor and L-glutamine supplementation, an antioxidant, on the glomerular morphology of rats. Methods: Twenty Wistar rats were distributed into four groups (n = 5): control (C); control treated with 2% L-glutamine (CG); rats with Walker-256 tumor (WT); and rats with Walker-256 tumor treated with 2% L-glutamine (WTG). Renal histological samples were submitted to periodic acid-Schiff and Masson's Trichrome staining to analyze glomerular density, morphometry of glomerular components and glomerulosclerosis; and to immunohistochemistry for fibroblast growth factor-2 (FGF-2). Results: WT showed 50% reduction in body mass gain and cachexia index > 10%, while WTG demonstrated reduction in cachexia (p < 0.05). WT revealed reduction of glomerular density, increase in the glomerular tuft area, mesangial area, matrix in the glomerular tuft, decrease in the urinary space and synechia, and consequently higher glomerulosclerosis (p < 0.05). L-glutamine supplementation in the WTG improved glomerular density, and reduced glomerular tuft area, urinary space, mesangial area, and glomerulosclerosis compared to WT(p < 0.05). WT showed higher collagen area and FGF-2 expression compared to C (p < 0.05). WTG presented lower collagen fibers and FGF-2 expression compared to WT (p < 0.05). Conclusions: L-glutamine supplementation reduced cachexia and was beneficial for glomerular morphology of the rats, as well as it reduced kidney damage and improved the remaining glomeruli morphology.
