As constructive cells of the glomerular filtration barrier, podocytes plays an essential role in the maintenance of the glomerular blood filtration, and also in the prevention of protein loose from blood. Many factors cause podocyte injury, and consequently contribute to the onset and progression of glomerular lesions. This review focuses on relationship between podocyte injury and glomerular disease.

Objective To evaluate the clinical efficacy and adverse effects of CAG regimen in treatment of primary, refractory and relapsed acute myeloid leukemia (AML) and high risk myelodysplastic syndrome (MDS), and analyse the factors influencing long-term survival. Methods Sixty-one patients with AML ( primary, n = 27; refractory, n = 18; relapsed, n = 16) and 9 patients with MDS were treated with CAG regimen. Examinations on liver and renal function, electrocardiogram and bone marrow cytology were performed before and after treatment, and adverse effects of CAG were observed. Short-term efficacy was evaluated based on clinical manifestation, peripheral blood and bone marrow cytologic examinations. Patients were followed up, overall survival ( OS) and disease free survival ( DFS) were analysed, and long-term efficacy of CAG regimen was evaluated. The factors influencing long-term survival were analysed by Log-rank test of survival curve. Results After a course of treatment by CAG regimen, the total effective rate was 71% , and 34 patients (49%) experienced complete remission. The median time of follow up was 45 months, the median OS was 28 months, and the median DFS was 23 months. Age, level of lactate dehydrogenase (LDH), remission condition after a course of treatment by CAG regimen and adoption of HD-Ara-C regimen as consolidation treatment were influencing factors for OS and DFS. The dominant clinical adverse effects were bone marrow depression, with 13 d as the median duration of agranulocytosis ( neutrophil <0.5 ×10~9/L) and 9 d as the median duration of thrombocytopenia (platelet <20 ×10~9/L). Conclusion CAG regimen may lead to favourable therapeutic effects in treatment of primary, refractory and relapsed AML and high risk MDS, and may yield less adverse effects and better long-term therapeutic effects. Age, level of LDH, remission condition after a course of treatment and adoption of HD-Ara-C regimen as consolidation treatment are dominant influencing factors for survival.

Objective To evaluate the growth inhibition and apoptosis of human monocytic leukemia THP-1 cell line by using 5,8-dimethyl-2-β-hydroxyisovalerylshikonin (SK36) and explore its preliminary mechanism. Methods CCK colorimetric assay and cell counting was used to examine the growth inhibition of shikonin on THP-1 cells. The apoptosis of THP-1 cells was detected by Annexin V/PI double labeling. The activation of Caspase-3 apoptosis pathway was determined by FCM. The apoptosis and the necrosis of THP-1 cells were detected by the laser scanning confocal microscopy. Results When the THP-1 cells were treated with SK36 at 1.02 μg/ml for 24 h and 48 h, the growth inhibition was dose-dependent. The cell apoptotic rate of THP-1 cells treated with 1.02 μg/ml evaluated by FCM with Annexin V/PI double labeling staining were (40.61 ±2.13) % and (67.40±9.15) % at 24 h and 48 h after treatment, respectively, which were significantly higher than that of the control group [(16.97±0.61) %] ([ = 18.444, t = 9.528, P <0.01). SK36 could induce THP-1 cells apoptosis involving the activation of Caspase-3 (F= 323.61, P<0.01). Conclusion SK36 can induce human THP-1 cells to undergo apoptosis, and its primary mechanism was to activate the Caspase-3.

Aim Toinvestigatetheeffectsoftriptonot-erpene methyl ether ( TME ) , a diterpene derived from the medicinal plant Triptergium wilfordii, on human gastric cancer AGS cell proliferation inhibition and ap-optosisinducedinvitro.Methods MTTassaywas used for screening tumor spectrum and detecting the vi-ability of AGS cells and normal human gastric epitheli-al cells GES-1 . Cell morphology was observed by light microscopy and AO / EB staining. Flow cytometry was used to detect cell apoptotic rate and cell cycle. JC-1 staining and fluorescence probe DCFH-DA were em-ployed to detect the changes of mitochondrial mem-brane potential and reactive oxygen species ( ROS ) . The effect of inhibiting AGS clonogenic survival was as-sayed by the method of plate clone formation. Western blot was used to analyse the expression of caspase-3 , caspase-8,Bcl-2andBax.Results MTTresults showed that TME exhibited significantly higher cytotox-icity to gastric cancer AGS cell line than to noncancer-ous cell line GES-1. IC50 for AGS of 48 h treatment was 23 . 85 μmol · L-1 . TME significantly inhibited colony formation and caused morphological changes in AGS cells. Annexin V-FITC / PI double staining showed the apoptotic rate increased. DCFH-DA stai-ning showed TME resulted in an increase in intracellu-lar ROS levels. Mitochondrial membrane potential de-creased after TME treatment. Western blot results showed that TME increased the proportion of Bax /Bcl-2 , with the activation of caspase-8 and caspase-3 . The broad-spectrum caspase inhibitor z-VAD-fmk pre-treatment reduced the expression of caspase-8 and caspase-3. TME enabled AGS cell cycle arrest in G0/G1phase.Conclusion TMEpossessespotenttumor selected toxicity and can induce apoptosis of AGS cells through cell cycle arrest, which is associated with Bcl-2 protein family.

Objective To investigate the effects of self-efficacy-oriented nursing intervention on postoperative quality of life of lung tumor patients. Methods Ninety patients with lung tumors undergoing chest surgery in our hospital from March 2010 to March 2012 , involved in the study. The nursing data were retrospectively analyzed for investigation of the nursing strategies. The patients were randomized into two group with random digits table in equal number: The control group received routine nursing and the intervention group with self-efficacy-oriented nursing intervention beside routine nursing care. 3 months after nursing intervention , the two groups were compared by Self-rating Depression Scale (SDS) and Self-rating Anxiety Scale (SAS) in terms of quality of life and psychological state. Results The scores of the intervention group by SDS and SAS were both significantly higher than those of the control group (P < 0.05). The scores of the intervention group on self efficacy and quality of life were significantly higher than those of the control (P < 0.05). Conclusion The self-efficacy-oriented nursing intervention applied in the postoperative nursing care to lung cancer patients can significantly improve the postoperative symptoms and psychological status. It can also improve their self efficacy and then enhance their quality of life.

The changes of serum malondialdehyde, myeloperoxidase, total antioxidant capacity, superoxide dismutase activity, and glutathione peroxidase were observed in patients with Graves′ disease. The myeloperoxidase level increased in patients with Graves′ disease. The balance between oxidation and antioxidative defense was disrupted in patients with newly-onset Graves′ disease. Oxidative stress seems to be related to hyperthyroidism.
