瞄准：在 Kupffer 房间的功能上检验 adiponectin 的效果，脂肪的多糖(LPS ) 的关键调节的人导致了肝损伤。方法：D-galactosamine (GalN ) 和 LPS intraperitoneally 被注入 adiponectin-/- 老鼠和野类型老鼠。Kupffer 房间，从 Sprague-Dawley 孤立老鼠，是 preincubated 与或没有 adiponectin，然后与 LPS 对待。结果：在猛烈老鼠， GalN/LPS 注射显著地降低了幸存率，显著地提起了丙氨酸转氨酶和肿瘤坏死 factor-alpha (TNF-alpha ) 的血浆层次并且显著地减少了与野类型老鼠相比的 IL-10 层次。在肝的 TNF-alpha 基因表示是哪个更高并且 IL-10 的那些比在野类型老鼠在猛烈老鼠是更低的。在有教养的 adiponectin-pre-treated Kupffer 房间， LPS 显著地降低了 TNF-alpha 层次并且在培养基和他们的各自的基因表示层次提起了 IL-10 层次，与没有 adiponectin-pre-treatment 的 Kupffer 房间相比。结论：Adiponectin supresses TNF-alpha 生产并且响应 LPS 刺激由 Kupffer 房间导致 IL-10 生产，并且 adiponectin 的缺乏提高导致 LPS 的肝损伤。

AIM To construct a non-invasive prediction algorithm for predicting non-alcoholic steatohepatitis(NASH), we investigated Japanese morbidly obese patients using artificial intelligence with rule extraction *** Consecutive patients who required bariatric surgery underwent a liver biopsy during the operation. Standard clinical, anthropometric, biochemical measurements were used as parameters to predict NASH and were analyzed using rule extraction technology. One hundred and two patients, including 79 NASH and 23 non-NASH patients were analyzed in order to create the predictionmodel, another cohort with 77 patients including 65 NASH and 12 non-NASH patients were analyzed to validate the *** Alanine aminotransferase, C-reactive protein, homeostasis model assessment insulin resistance, albumin were extracted as predictors of NASH using a recursive-rule extraction algorithm. When we adopted the extracted rules for the validation cohort using a highly accurate rule extraction algorithm, the predictive accuracy was 79.2%. The positive predictive value, negative predictive value,sensitivity and specificity were 88.9%, 35.7%, 86.2% and 41.7%, *** We successfully generated a useful model for predicting NASH in Japanese morbidly obese patients based on their biochemical profile using a rule extraction algorithm.
