The pathogenesis of heart failure is a complex progression and associated with abnormal regulation of many signaling pathways. As a cofactor of hemoglobin, myoglobin, oxidative respiratory chain, DNA synthase and other important proteins, iron plays an indispensable role in myocardial energy metabolism. Recently, a large number of studies have shown that heart failure is related to the disorder of iron metabolism. Both iron deficiency and iron overload can lead to the development of a variety of cardiomyopathy, and even progress to heart failure. Iron metabolism could be a key target for the diagnosis, prevention and treatment of heart failure. Here, we review the basic process of iron metabolism and its mechanism in heart failure, expecting to provide new clues and evidence for the treatment of heart failure.

Objective To study the oxidative stress and apoptosis relative protein expression in rat striatum during the pathogenesis of Parkinson's disease (PD) induced by 6-hydroxydopamine (6-OHDA). Methods 6-OHDA was stereotacticly injected into the right striatum of the rats at two sites to produce PD models. Activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), contents of reduced glutathione (GSH) and malondialdehyde (MDA) in the injured and normal striatum were measured using assay kits; and levels of Bax and Bcl-2 were detected by Western blotting in injured striatum. Results In 10 successful PD rats, compared with either the sham group or the normal group, activities of SOD and GSH-Px and contents of GSH in the right striatum significantly decreased while contents of MDA increased obviously (P<0.05); And levels of Bax significantly increased while expression of Bcl-2 obviously decreased. Conclusion Oxidative stress plays a key role in the pathogenesis of PD. Furthermore, Bax and Bcl-2 were involved in the regulation of apoptosis under oxidative stress induced by 6-OHDA.

One of the challenges in andrology nowadays is the diagnosis and treatment of external genital abnormalities and defects along with the consequent voiding, sexual, and reproductive dysfunctions, for which no guidelines are yet available. Hitherto, surgical repair and reconstruction are efficient for these diseases. The key to these operations is to individualize surgical strategies according to the specific local lesion and dysfunction, usually involving flap and graft techniques. This article presents our experience in the surgical treatment of penile and scrotal abnormalities and defects with urological and andrological techniques and microsurgical strategies, focusing on the external repair and functional reconstruction. Satisfactory treatment outcomes pivot on a precise evaluation of the disease, a rational design of surgical procedures, and an earnest communication with the patient. Some cases are rather complicated and challenging, usually with complications, and therefore deserve further researches for more effective treatment strategies in clinical practice.

Objective:To study the effect of Ginkgo biloba extract (EGb761) on metabolism of aflatoxin B_1(AFB_1) in Wistar rats. Methods:Seventy one Wistar rats were divided into three groups at random: group A (AFB_1 group), group B (AFB_1+EGb761 group), and group C (control group). The rats in groups A and B were given AFB_1(intraperitoneal injection, 100-200 μg/ kg body weight, 1-3 times/week). The rats in group B were fed the food containing EGb761 while the rats in groups A and C were given normal food. Blood samples were collected and liver biopsy was performed on the 14th, 28th and 42nd week. All the rats were sacrificed at the 64th week. The incidence of hepatoma was observed. The hepatic phase Ⅰ drug-metabolizing enzyme CYP450 and phase Ⅱ enzyme GST were detected by spectrometry. The serum AFB_1-lysine adduct was determined by high performance liquid chromatography (HPLC). The expression of 8-hydroxydeoxyguanosine(8-OHdG) was measured by immunohistochemistry. Results:The incidence of hepatocellular carcinoma (HCC) in group B was significantly lower than that in group A (26.92% vs 76.00%,P<0.001). No hepatocellular carcinoma developed in group C. EGb761 had no effects on the activities of CYP450 and GST in rat liver tissues. The level of AFB_1-lysine adduct reached the peak (4 356.01 pg/mg albumin) at the 14th week in group A. EGb761 significantly inhibited the formation of AFB_1-lysine adducts in serum by 13.07% at the 14th week (P=0.033), and 73.63% at the 42nd week (P=0.002). The expression of 8-OHdG protein in rat liver tissues in group B was significantly lower than that in group A at the 28th, 42nd, and 64th week (P<0.05). Conclusion:The main mechanism underlying the effect of EGb761 in blocking hepatogenesis induced by AFB_1 may not be fully related with its influence on the activity of liver phase Ⅰ and phase Ⅱ metabolizing enzymes. EGb761 inhibites the production of AFB_1-lysine addcuts, decreases the expression of 8-OHdG protein, and finally alleviates the DNA oxidative injury, which may be one of the mechanisms for the effects of EGb761 in inhibiting or delaying hepatogenesis induced by AFB_1.
