ABSTRACT
ABSTRACT Introduction: Gymnastics requires high-level body coordination and control. The key to success for gymnasts is to control and adjust the center of gravity through the abdominal core muscles. Abdominal core resistance training is mainly aimed at fulfilling this purpose. Objective: Analyze the results of abdominal core resistance training on the fitness of gymnasts. Methods: 20 volunteer gymnasts were selected by random sampling. The experimental participants were tested for functional exercise capacity. The study focused on the athletes' weaknesses during exercise. After completing the abdominal core resistance training, the fitness test was performed. The data obtained were analyzed statistically. Results: The peaks of the flexor and dorsal muscles were significantly enhanced (P<0.05). There was no significant difference between the two groups before and after training of body flexors and extensors (P>0.05). Conclusion: Abdominal core resistance training plays a positive role in improving the fitness of gymnasts. Coaches can actively introduce abdominal core resistance training into their regular exercises to improve athletes' fitness.

RESUMO Introdução: A ginástica exige coordenação e controle corporal de alto nível. A chave para o sucesso dos ginastas é controlar e ajustar o centro de gravidade através dos músculos do centro abdominal. Os exercícios de força do centro abdominal visam principalmente cumprir este propósito. Objetivo: Analisar os resultados do treinamento de força muscular no centro abdominal sobre a aptidão física dos ginastas. Métodos: 20 ginastas voluntários foram selecionados por amostragem aleatória. Os participantes experimentais foram testados quanto à capacidade de exercício funcional. O estudo focalizou os pontos fracos dos atletas durante o exercício. Após a conclusão do exercício de força do centro abdominal, efetuou-se o teste de aptidão física. Os dados obtidos foram analisados por estatisticamente. Resultados: Os picos dos flexores e músculos dorsais foram significativamente aprimorados (P<0,05). Não houve diferença significativa entre os dois grupos antes e depois do treinamento de flexores e extensores corporais (P>0,05). Conclusão: O exercício da força do centro abdominal tem um papel positivo na melhoria da aptidão física dos ginastas. Os treinadores podem introduzir ativamente o treino de força do centro abdominal nos exercícios habituais para melhorar a aptidão física dos atletas.

El estudio se centró en los puntos débiles de los atletas durante el ejercicio. Después de completar el ejercicio de fuerza del núcleo abdominal, se realizó una prueba de aptitud física. Los datos obtenidos se analizaron estadísticamente. Resultados: Los picos de los músculos flexores y dorsales aumentaron significativamente (P<0,05). No hubo diferencias significativas entre los dos grupos antes y después del entrenamiento de los flexores y extensores del cuerpo (P>0,05). Conclusión: El ejercicio de fuerza del núcleo abdominal tiene un papel positivo en la mejora de la condición física de los gimnastas. Los entrenadores pueden introducir activamente el entrenamiento de la fuerza del núcleo abdominal en los ejercicios habituales para mejorar la forma física de los deportistas.

ABSTRACT
Abstract Objective To investigate the indoor environmental risk factors to provide measures for the prevention and control of otitis in preschool children. Method In this cross-sectional study, a questionnaire survey was administered to preschool children aged 2-7 years from 60 kindergartens in six districts of Urumqi City in August 2019. Multiple regression was run to predict influence factors for otitis media in preschool children. Result A total of 8153 valid questionnaires were collected. After adjusting for age, the prevalence of otitis among preschool children in Urumqi was 13.1%. Multivariate logistic regression showed that previous antibiotic treatment, treatment with one to two antibiotics before 1 year of age, presence of walls with aqueous or latex paint, use of carpet floor bedding in rooms, newly decorated homes of mothers before pregnancy, purchase of new furniture for homes of children at 0-1 year of age, and presence of flowering plants in the residence of children at 0-1 years of age were all identified as risk factors for the development of otitis in children. Conclusion Parents should also pay attention to indoor living environments, and reduce indoor renovation in the homes of children during their growth and development, which can positively improve children's indoor living environment, thus effectively preventing otitis in preschool children.
ABSTRACT
Aim: This study aimed to compare clinical and oncological outcomes of robot-assisted and laparoscopic surgery for rectal cancer. Materials and Methods: We searched PubMed/Medline, Embase, the Cochrane Library, Yahoo, and Google Scholar databases for relevant articles published up to 2017. Studies based on comparability between robot-assisted and laparoscopic surgery for rectal cancer were designated. Clinical outcomes included operative time, conversion to open surgery, estimated blood loss (EBL), bowel function recovery time, length of hospital stay (LOS), anastomosis leak, and postoperative complications. Oncological outcomes comprised the number of lymph nodes extracted, the positive circumferential margin (PCRM), and the distal resection margin (DRM) Results: Twenty studies were designated totaling 5496 patients, comprising a robot-assisted surgery patient group (n = 2168, 39.4%) and a laparoscopic surgery patient group (n = 3328, 60.6%). The robot-assisted surgery group was associated with longer operative time (odds ratio [OR] 0.48, 95% confidence interval [CI]; 0.14, 0.82), lower conversion to open surgery rate (OR 0.55, 95% CI; 0.44, 0.69), shorter LOS (OR − 0.15, 95% CI; −0.30, 0.00), faster bowel function recovery (OR − 0.38, 95% CI; −0.74, −0.02), and lower postoperative complications (OR 0.79, 95% CI; 0.65, 0.97). EBL, anastomosis leak rate, and oncological outcomes including the number of lymph nodes extracted, the DRM, and the PCRM showed no significant differences between groups. Conclusion: Robot-assisted surgery for rectal cancer showed longer operative time, lower conversion, faster bowel function recovery rates, and shorter hospital stay, and similar oncological outcomes compared to laparoscopic surgery
ABSTRACT
@#Objective To investigate the significance of neoadjuvant chemotherapy in the treatment of limited-disease small cell lung cancer (LD-SCLC). Methods We retrospectively analyzed the clinical data of 55 LD-SCLC patients who underwent surgery in the Department of Thoracic Surgery, China-Japan Friendship Hospital from May 2007 to August 2016. There were 42 males and 13 females with a mean age of 57 years. All patients underwent clinical staging before treatment. According to the different treatments, the patients were divided into two groups, a preoperative neoadjuvant chemotherapy group and a direct surgery group. The comparison of long-term survival rates was made between the two groups. Results Among the 55 patients, median survival time was 27 months. The 1-, 3-, 5-year survival rate was 89.1%, 45.0%, 33.8% respectively. Treatment methods and clinical N stage were significantly different in prognosis (P<0. 05). The results of Cox proportional hazards regression model showed that clinical N stage was prognostic factor of LD-SCLC patients (P<0. 05). Conclusion Patients with clinical stage Ⅰ and Ⅱ SCLC are better to receive direct surgery. For patients with clinical stage Ⅲ, it is recommended to reach partial response or complete response with neoadjuvant chemotherapy before surgery. The status of lymph node metastasis is closely related to survival, thus identifying the accurate clinical stage is crucial before treatment.
ABSTRACT
@#Small cell lung cancer is a pathological type with higher malignancy in lung cancer, and has biological characteristics different from non-small cell lung cancer, such as rapid growth, high malignancy and poor prognosis. Mediastinal lymph node and distant metastasis occur frequently. In recent years, the treatment of limited-stage small cell lung cancer has been stagnant, and various treatments are poor. The operation is mainly suitable for patients with small cell lung cancer (T1-2N0M0). Small cell lung cancer has strong sensitivity to chemotherapy, but the clinical application of neoadjuvant chemotherapy in T1-2N0M0 small cell lung cancer remains controversial. This article reviewed the value of neoadjuvant chemotherapy in the treatment of T1-2N0M0 small cell lung cancer.
