Influence of functional training on teaching table tennis to college students / Influência do treinamento funcional no ensino de tênis de mesa em estudantes universitários / Influencia del entrenamiento funcional en la enseñanza de tenis de mesa en estudiantes universitarios

ABSTRACT Introduction: Contemporary table tennis teaching lacks attention to global abilities; some studies suggest that functional training can supply the demands of the high level of sport competition. Objective: Study the effect of functional training on teaching table tennis to college students. Methods: A controlled random selection was carried out (n=40), in which the experimental group (n=20) chose a functional training program. In contrast, the control group (n=20) participated in the teaching of traditional table tennis skills. The training frequency was one hour daily, three times a week, lasting six weeks. Table tennis-specific fitness was assessed before and after the experiment. Data were cataloged and statistically analyzed. Results: On the manual skills index, the experimental group's score increased from 63,194 to 79,683 points after the experiment, and the control group's score increased from 64,788 to 68,775 points after the experiment. In the regression index, the experimental group score increased from 63.645 to 78.614, and the control group score increased from 64.152 to 70.574. Conclusion: The functional training mode proposed in this paper can rapidly improve the competitive level of table tennis and improve the competitive performance of its practitioners.

RESUMO Introdução: O ensino contemporâneo no tênis de mesa carece de atenção em habilidades globais, alguns estudos sugerem que o treinamento funcional possa suprir as demandas requisitadas pelo alto nível de competição esportiva. Objetivo: Estudar o efeito do treinamento funcional sobre o ensino do tênis de mesa nos estudantes universitários. Métodos: Foi realizada uma seleção randômica controlada (n=40), na qual o grupo experimental (n=20) escolheu um programa de treinamento funcional, enquanto o grupo de controle (n=20) participou do ensino das habilidades tradicionais do tênis de mesa. A frequência do treinamento foi de uma hora diária, três vezes por semana, com duração de seis semanas. A aptidão física específica do tênis de mesa foi avaliada antes e depois do experimento. Os dados foram catalogados e analisados estatisticamente. Resultados: No índice de habilidades manuais, a pontuação do grupo experimental aumentou de 63.194 para 79.683 pontos após o experimento, e a pontuação do grupo de controle aumentou de 64.788 para 68.775 pontos após o experimento. No índice de retrocesso, a pontuação do grupo experimental aumentou de 63.645 para 78.614, e a pontuação do grupo de controle aumentou de 64.152 para 70.574. Conclusão: O modo de treinamento funcional proposto neste artigo pode melhorar rapidamente o nível competitivo do tênis de mesa e melhorar o desempenho competitivo de seus praticantes.

Non-junctional Cx32 mediates anti-apoptotic and pro-tumor effects via epidermal growth factor receptor in human cervical cancer cells / 中国药理学与毒理学杂志

ABSTRACT:OBJECTIVE To investigate the role of connexin proteins (Cx), which form gap junctions (GJ), in progression and chemotherapeutic sensitivity of cervical cancer (CaCx). METHODS We analyze the expression of Cx26, Cx30, Cx32 and Cx43 in human specimens consisting of: Normal cervix (n=78), CaCx FIGO stage Ⅰ (n=148), CaCx FIGO stage Ⅱ (n=165). InCaCx cell lines, Hela- Cx32 (induced expression by doxycycline), C- 33A (endogenously express Cx32) and siHa (transiently transfected plasmid with Cx32), we detected the role of Cx32 against tostreptonigrin/cisplatin-induced apopotosisin presence or absence of functional GJ through using GJ inhibitors or low density cultural.Furtherly, we observed the relativity of Cx32 and EGFR expression in human specimens. Also, we detected the role of EGFR signaling pathway in the process of Cx32 anti-apoptosis through suppressed EGFR expression by inhibitors or siRNA sequences in cell lines. RESULTS We firstly demonstrated the expression of Cx32 was highly upregulated and accumulated in cytoplasm in the CaCx specimens, and the degree of upregulation correlated with advanced FIGO stages. Thus,in three human cervical cell lines, Cx32 was shown to suppress apoptosis when GJ formation is inhibited. No matter in cases of CaCx or cell lines, Cx32 expression was highly correlated with expression of EGFR and the EGFR pathway is an essential component of the Cx32-induced anti-apoptotic effect. CONCLUSION Cx32, traditionally tumor suppressive protein, was shown to be tumor protective against chemotherapy through EGFR pathway in a GJ-independent way.

The role of glucocorticoid in treating cytomegalovirus pneumonia following renal transplantation / 中华器官移植杂志

Objective To study the role of glucocorticoid (GC) in treating patients with cyto- megalovirus (CMV) pneumonia following renal transplantation.Methods There were 75 cases CMV pneumonia following renal transplantation during one month (3 cases),2-6 months (64 cases) and more than 6 months (8 cases).All patients were subjected to the comprehensive treatments including anti-virus therapy.In 47 cases,GC was given (GC group),and in the rest 28 cases,GC was not administered (non-GC group).Results In GC group,40 cases (85.1%) were cured and there were 7 deaths (14.9%).In non-GC group,17 cases (60.7%) were cured and there were 11 deaths (39.3%).There was significant difference between two groups (P
