Multiple factors affect the regeneration of liver

SUMMARY OBJECTIVE To study factors affecting the liver regeneration after hepatectomy METHODS With 3D reconstitution technology, liver regeneration ability of 117 patients was analysed, and relative factors were studied. RESULTS There was no statistically difference between the volume of simulated liver resection and the actual liver resection. All livers had different degrees of regeneration after surgery. Age, gender and blood indicators had no impact on liver regeneration, while surgery time, intraoperative blood loss, blood flow blocking time and different ways of liver resection had a significant impact on liver regeneration; In addition, the patients' own pathological status, including, hepatitis and liver fibrosis all had a significant impact on liver regeneration. CONCLUSION 3D reconstitution model is a good model to calculate liver volume. Age, gender, blood indicators and biochemistry indicators have no impact on liver regeneration, but surgery indicators and patients' own pathological status have influence on liver regeneration.

RESUMO OBJETIVO Estudar os fatores que afetam a regeneração hepática após hepatectomia. MÉTODOS A capacidade de regeneração hepática de 117 pacientes foi analisada com a tecnologia de reconstituição 3D e foram estudados os fatores relacionados. RESULTADOS Não houve diferença estatística significante entre o volume de ressecção hepática simulada e a ressecção atual. Todos os fígados apresentaram diferentes graus de regeneração após cirurgia. Idade, gênero e indicadores sanguíneos não tiveram impacto na regeneração hepática, enquanto que tempo de cirurgia, perda sanguínea intraoperatória, tempo de bloqueio do fluxo sanguíneo e diferentes formas de ressecção mostraram impacto significante na regeneração do órgão. Além disso, condições patológicas dos pacientes, incluindo hepatite e fibrose hepática, tiveram impacto significante na regeneração hepática. CONCLUSÃO O modelo de reconstituição 3D é um bom modelo para calcular o volume do fígado. Idade, gênero, indicadores sanguíneos e bioquímicos não tiveram impacto na regeneração hepática, mas indicadores operatórios e condição patológica dos pacientes mostraram influência na regeneração do órgão.

Continuous positive airway pressure treatment for functional cardiac arrhythmias combined with obstructive sleep apnea hypopnea syndrome / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To discuss the effect of continuous positive airway pressure (CPAP) treatment for functional cardiac arrhythmias combined with obstructive sleep apnea hypopnea syndrome.</p><p><b>METHODS</b>Fifty-six OSAHS patients combined functional cardiac arrhythmia were randomized divided into two groups. The 28 patients in the control group were treated with metoprolol according to cardiac guidelines, the other 28 cases in the experimental group were treated with CPAP therapy combined with metoprolol. AHI and the lowest oxygen saturation (LSaO2) were tested before and after treatment.</p><p><b>RESULTS</b>The efficiency rates were 57.1% and 17.9% in experimental and control group respectively, with statistical difference (χ2 = 7.62, P < 0.01). Total effective rates were 85.7% and 53.6% respectively, with statistical difference (χ2 = 5.41, P < 0.05). In the experimental group, there were three treatment subgroups. After treatment, AHI and the lowest oxygen saturation were significantly different (P < 0.05).</p><p><b>CONCLUSION</b>CPAP treatment can effectively eliminate respiratory disturbance index, improve the symptoms of hypooxygen at night, and effectively improve the therapeutic effect of functional cardiac arrhythmias in OSAHS patients combined with functional arrhythmia.</p>
