ABSTRACT
Madelung's disease is more common in male patients who drink alcohol. It can affect many parts of the body, but rarely affects scrotum. A case of Madelung's disease involving the scrotum was reported. The scrotum tumor was removed by operation and good results were obtained. No recurrence was found in the follow-up of 14 months. Surgical resection could be an effective treatment for this disease.
ABSTRACT
Objective To investigate the diagnostic value of prostate specific antigen density (PSAD),Gleason score and serum ferritin (SF) in bone metastases from prostate cancer.Methods 45 patients diagnosed with bone metastases from prostate cancer in our hospital from January 2015 to October 2017 were selected as metastasis group.90 cases without bone metastases in prostate cancer were selected as control group.The PSAD,SF and Gleason scores of the two groups were measured and compared.Receiver operating characteristic (ROC) curve was used to analyze the three indexes to predict the clinical value of bone metastases in patients with prostate cancer.Results The serum PSA,SF,prostate volume,PSAD levels in metastasis group were significantly higher than those in the control group,with statistically significant difference (P ＜ 0.05);the average Gleason scores metastasis group were significantly higher than the control group (P ＜ 0.05);The sensitivity and specificity of SF combined with PSAD and Gleason score diagnosis in patients with prostate cancer bone metastasis was 95.64％ and 91.30％ respectively,the area under the curve (AUC) value is 0.930.Conclusions Detection and analysis of PSAD,SF,and Gleason scores in patients with prostate cancer will help to evaluate whether or not the patients have bone metastases.
ABSTRACT
Objective: To To investigate the changes of MicroRNA-134, CREB and p-CREB expression in epileptic rat brains in order to elucidate the molecular mechanisms of epilepsy, providing new ideas for clinical treatment. Methods: Sixty-four Spraque-Dawley (SD) rats were divided into groups randomly, including control group, six hours after seizure group, 24-hour group, three-day group, one-week group, two-week group, four-week group, and eight-week group. All groups were placed under a pilocarpine-induced epilepsy model except the control group, and all rats were decapitated in different points of time. Brain specimens were taken for quantitative PCR experiments, immunohistochemistry and Western blot experiments. The results of the epilepsy model groups and the control group were compared. Results: There were no significant differences between the six hours after seizure group, the 24-hour group and the control group about the MicroRNA-134 levels. MicroRNA-134 in the hippocampus tissue of the three-day group significantly reduced compared with the control group; same result was observed with the one-week, two-week, four-week and eight-week groups. The CREB and p-CREB levels in the three-day group’s rat hippocampus significantly increased compared with the control group; and the high levels of CREB and p-CREB were constantly maintained in the one-week, two-week, four-week and eight-week groups. Conclusions: The MicroRNA-134 level of the epileptic rat hippocampus is significantly lower than normal after three days, and continues to maintain a low level; while CREB and p-CREB levels are rsignificantly increased after three days, and continue to remain at a high level. MicroRNA-134 plays a role in inhibiting synaptic plasticity by inhibiting CREB and p-CREB expressions.
