ABSTRACT

Objectives: The goal of this research was to see how reliable and valid three selected parameters from different analysis were in detecting the vertical skeletal pattern. Methods: There were 94 cephalometric x?rays used in all. The vertical skeletal pattern was assessed using the mandibular plane angle by Steiner, Frankfort mandibular angle by Tweed, and facial axis angle by McNamara. According to the diagnostic results of the majority of the measures, the samples were classified as normo?divergent, hypodivergent, or hyperdivergent. Kappa statistics, positive predictive value, and sensitivity were employed to verify the validity and reliability of the analyses. Results: A statistically significant weak negative correlation was found between Frankfort mandibular angle and facial axis angle in female group (p value < 0.01). A good agreement was found between mandibular plane angle with final diagnosis (K = 0.726). The mandibular plane angle showed highest sensitivity and positive predictive value in hypodivergent group (0.939, 0.816) and normo?divergent group (0.795, 0.833), respectively. Conclusion: For determining the facial vertical growth pattern the most accurate indicators were identified to be mandibular plane angle (SN?GoGn) and Frankfort mandibular angle.

ABSTRACT

Ashi points play a significant role in the clinical localization and qualitative diagnosis of acupuncture, as well as in selecting acupoints along the meridians and applying tonifying or reducing techniques. This paper introduces the theoretical basis and existing technical methods of objectification of ashi point diagnosis and treatment. It proposes that using sensory quantitative testing to determine the temperature and tenderness thresholds of ashi points could help to identify the pathological characteristics of "cold" "heat" "deficiency" or "excess" of ashi points. In addition, the possibility of objectification of ashi point diagnosis-treatment plan is explored from three perspectives, precision of selection of ashi point therapy, objectification of effect evaluation of ashi point analgesia, and differentiation of the studies on ashi point analgesic mechanism, aiming to provide new research ideas for the modernization of traditional Chinese acupuncture.

ABSTRACT

Introducción: el apoyo al automanejo, la participación y retroalimentación son centrales en la implementación de una atención centrada en el usuario en el marco del modelo de cuidados crónicos. Esto ha demostrado mejorar diversos resultados sanitarios. Objetivo: estimar el grado de participación de los pacientes hipertensos y diabéticos, en las decisiones sobre su plan de tratamiento en población adulta chilena. Métodos: análisis secundario de la Encuesta Nacional de Salud (ENS) 2016-2017, muestra aleatoria estratificada de hogares, multietápica por conglomerados, representativa de la población adulta chilena. Se incluyó población mayor de 15 años hipertensa o diabética bajo tratamiento. Se describen las prevalencias expandidas de la variable percepción de participación en la toma de decisio-nes sobre plan terapéutico en escala Likert de 5 niveles, según edad, sexo, zona urbana/rural y nivel educacional. Se utilizó regresión logística y OR ajustados. Resultados: el 72,3% de los diabéticos y el 71,9% de los hipertensos, refieren "nunca" haber sido consultados al preparar su plan de tratamiento. En la población hipertensa, existe una percepción de participación significativamente más baja en mujeres que en hombres (OR ajustado por edad = 0,5 (IC 95% de 0,3-0,8) no se observaron diferencias estadísticamente significativas según edad, ruralidad ni nivel educacional. Conclusiones: la población hipertensa y diabética percibe bajos niveles de participación en el diseño de su plan terapéutico y los resultados sugieren inequidad de género en hipertensos. Este estudio permitirá evaluar futuras políticas y modificaciones al modelo de cuidados crónicos en el sistema de salud chileno.


Introduction: Self-management support, activation, participation, and feedback are core elements in chronic care models. Patients' participation in decision-making has been shown to improve health outcomes. Objective: To estimate the degree of participation of hypertensive and diabetic patients in decisions about their treatment plan in the general Chilean adult population. Methods: Secon-dary analysis of the "Encuesta Nacional de Salud (National Health Survey) (ENS) 2016-2017" multistage random stratified sample of households representative of the Chilean adult population. Hypertensive or diabetic populations older than 15 years of age that were under treatment were included. The weighted prevalence of the variable "perception of participation in decision making about their treatment plan" was described on a Likert scale of 5 levels, according to age, sex, urban/rural area, and educational level. We used logistic regression and adjusted OR. Results 72.3.5% of diabetic and 71.9% of hypertensive patients say they have "never" been asked their opinion about their treatment plan. In the hypertensive population, women perceived less participation than men (OR adjust by age =0.5 [IC 95% de 0.3-0.8]), with no significant differences observed by age, rurality, or educational level. Conclusions: Hypertensive and diabetic populations perceive low levels of participation in the design of their therapeutic plan, results also suggest gender inequity. This study contributes essential insights for the reformulation of Chilean chronic care models and may stand as a baseline to evaluate the implementation of future health policy.

ABSTRACT

Objective:To analyze the dosimetric effects on off-center tumour treatment plan resulting from the MR-Linac-based isocenter position radiotherapy plan.Methods:The cases of 19 patients who were treated in Sun Yat-sen University Cancer Center in 2020 were collected in this study. Two different IMRT plans were designed for each patient with off-center tumor both for group A with planned isocenter position as IMRT and group B with planed target center position as geometric center. The conformity index and homogeneity index of target, the dose normal tissue and the number of MU were compared between two plans.Results:The two IMRT plans met clinical dosimetric requirements. No statistical differences were found both in homogeneity index and conformity index ( P>0.05). Also there was no differences found in doses to normal tissues. However, the MU number (1 149±903, t=2.804, P=0.012) in group A was higher than that in group B (970±652). Conclusions:It is feasible to perform MR-Linac-based off-center treatment plan.

ABSTRACT

BACKGROUND: The diagnosis and treatment of the terrible triad of the elbow have achieved a breakthrough. OBJECTIVE: To introduce the definition, basic anatomy, stable structure, injury mechanism and classification of terrible triad of the elbow, and to discuss the treatment plan deeply. METHODS: The first author searched PubMed, CNKI and Wanfang databases for the articles published before September 2019. The keywords were “terrible triad of the elbow, elbow joint, fracture dislocation” in English and Chinese, respectively. A large number of articles concerning the terrible triad of the elbow in recent years were reviewed, and the treatment strategy was summarized. RESULTS AND CONCLUSION: For the terrible triad of the elbow, the operator must carefully check the patient before operation, carefully analyze the imaging examination results and three-dimensional printed model, and accurately judge the bone structure of the elbow and degree of ligament injury. During the operation, the stability of the radial head, the fracture of the coronoid process and the injury of the lateral ligament complex are usually reconstructed through a single lateral approach or a combination of internal and external approaches. Then, the stability of elbow joint is tested to determine whether it is necessary to repair the medial ligament complex or use the hinged external fixator to restore the stability of elbow joint. Early active rehabilitation is needed. The above systematic treatment can reduce postoperative complications, accelerate fracture healing, and improve elbow joint function and patients’ quality of life.

ABSTRACT

The outbreak of pneumonia caused by novel coronavirus (COVID-19) at the end of 2019 was a major public health emergency in human history. In a short period of time, Chinese medical workers have experienced the gradual understanding, evidence accumulation and clinical practice of the unknown virus. So far, National Health Commission of the People's Republic of China has issued seven trial versions of the "Guidelines for the Diagnosis and Treatment of COVID-19". However, it is difficult for clinicians and laymen to quickly and accurately distinguish the similarities and differences among the different versions and locate the key points of the new version. This paper reports a computer-aided intelligent analysis method based on machine learning, which can automatically analyze the similarities and differences of different treatment plans, present the focus of the new version to doctors, reduce the difficulty in interpreting the "diagnosis and treatment plan" for the professional, and help the general public better understand the professional knowledge of medicine. Experimental results show that this method can achieve the topic prediction and matching of the new version of the program text through unsupervised learning of the previous versions of the program topic with an accuracy of 100%. It enables the computer interpretation of "diagnosis and treatment plan" automatically and intelligently.

ABSTRACT

Objective@#To summarize the treatment options for congenital maxillary lateral incisor agenesis (MLIA).@*Methods @#Review the literature, summarize the current treatment options and advantages and disadvantages of various methods of MLIA, and analyze cases. @*Results @#When a patient′s occlusion and other conditions are suitable for space closure and canine substitution, closure of the gap is the recommended method, as it has good aesthetic results and leads to good periodontal health. However, when closure cannot be performed, a dental implant has a strong advantage compared with other restoration methods. When planning implants for MLIA patients, doctors should carefully select the correct surgery time and take care with the implant position to obtain good results.@* Conclusion@#In the choice of a treatment plan for MLIA, we need to use the concept of multidisciplinary combined treatment to obtain a more satisfactory treatment effect with regard to aesthetics and function.

ABSTRACT

Objective@#To compare the dosimetrics of the plan target volume (PTV) and organs at risk (OARs) between two treatment planning approaches for patients with multiple brain metastases from non-small cell lung cancer on CyberKnife.@*Methods@#20 patients with multiple metastases from lung carcinoma were reviewed and analyzed, who had been treated by CyberKnife from December 2017 to December 2018. The CyberKnife stereotactic radiotherapy plans of the 20 cases were re-planed with single plan for multiple lesions and multiple plans per lesion. The dosimetry differences of PTV and OARs isodose disribution, conformity index (CI), total beam counts and total monitor units (MUs) were compared in the two types of plans.@*Results@#The two types of plans could satisfy over 95% PTV coverage of the prescription dose. The maximum and mean dose of normal brain adjacent to the PTV were reduced in multiple plan approach effectively. Moreover, the maximum and mean dose of OARs (brainstem) dropped by 1.62% and 5.57% (t=1.09, P<0.01) respectively. The number of treatment nodes and total MU declined by 4.63% (t=1.87, P<0.01)and 1.06% in multiple plan approach, which could significantly shorten the clinical treatment time. The differences in CI index between these two types of plans was of no statistical significance.@*Conclusions@#For patients with multiple brain metastases of similar diameter and volume from non-small cell lung cancer to be treated on CyberKnife, multiple plans per lesion could not only reduce dose to normal brain tissue and OARs, but also improve the treatment efficiency.

ABSTRACT

@# Objective: To investigate the therapeutic effect of dendritic cell-induced killer cells (DC-CIK) combined with 5-fluorouracil (5-FU) and loaded with CD133+ HT-29 cell lysate or RNA on mice bearing colon cancer HT-29 cell transplanted tumor, and to explore the underlying mechanism. Methods: Colon cancer xenograft model was established in BALB /c nude mice by using human colon cancer HT-29 cells at logarithmic growth phase; Antigen-free DC-CIK, 5-FU+DC-CIK, R+DC-CIK (loaded with total RNA of CD133+ cells), L+DC-CIK (loaded with CD133+ cell lysate), 5-FU and normal saline were respectively injected into transplanted mice, and the treatment efficacies on the growth of transplanted tumor in each group after three treatment cycles were observed, and the tumor growth curve was drawn. The nude mice were sacrificed by cervical dislocation and the tumor volume and body weight were measured. qPCR was used to detect the expression of AKT mRNA in transplanted tumor tissue, and WB was used to detect the expression of phosphorylated AKT protein. Results: After treatment, the body mass of nude mice in R+DC-CIK group, L+DC-CIK group and 5-FU+DC-CIK group increased steadily, while the body mass of nude mice in DC-CIK group and 5-FU group decreased gradually; the tumor growth speed of nude mice in R+DC-CIK group, 5-FU+DC-CIK group and L+DC-CIK group was significantly slower than that of the control group (P<0.05). Compared with 5-FU and DC-CIK alone, the combined treatment with loaded lysate/RNA had more sig nificant effect on mRNA and protein expressions of AKT(P<0.05). Conclusion: The effect of DC-CIKwithdifferentloadingoritscombinationwith5-FUisbetterthanthatofchemotherapy alone. One of the mechanisms is related to the down-regulation ofAKT level.

ABSTRACT

Objective To analyze the radiation dose to the normal lung tissue of patients with early stage of non-small cell lung cancer treated by Cyberknife. Methods A retrospective analysis was conducted by summarizing the treatment plans of 264 patients with early stage non-small cell lung cancer from January 2011 to December 2013 in Tianjin Medical University Cancer Institute and Hospital. Sorted by the tumor volumes and locations, the Cyberknife plans were evaluated by means of dose volume histograms ( DVH) , homogeneity indexes ( HI) , percentage volumes receiving at least x Gy ( Vx ) of dose, i. e. , V5 , V10 , V20 , and V30 of the ipsilateral and contralateral lungs. For the tumors approximate to the hilus, the contralateral lungs were included in the optimization process, and the dose-volume metrics were analyzed for the contralateral and bilateral lungs. Results For the tumors close to the chest wall, V5≥(15. 21 ± 3. 12)% in ipsilateral lung tissue and V5≥(1. 34 ± 0. 67)% in contralateral lung tissue were observed. For the tumors near the hilus, V5≥(39. 4 ± 11. 90) % in ipsilateral lung tissue and V5≥(1. 48 ± 0. 34) % in contralateral lung tissue were observed. The irradiated volume ratios of both ipsilateral and contralateral lung tissue increased with the enlargement of tumor sizes. After including the contralateral lung tissue into the optimization, the irradiated volume ratios of the contralateral and bilateral lung tissue (V5,V10) decreasedsignificantly(t=2.44,4.81,3.53,3.17,P<0.05). Conclusions Higherriskof radiation injury in both ipsilateral and contralateral lung tissue can be expected for tumors near the hilus than near the chest wall. After including contralateral lung tissue into the planning optimization, lower dose to the contralateral and whole lung tissue was achieved, indicating a better protection of normal lung tissue.
