Dynamin-related protein 1 (Drpl) is a major protein for regulating mitochondrial fission.Its activity is associated with the post-translational modification,mainly including phosphorylation,ubiquitination,sumoylation,and S-nitrosylation.During the cerebral ischemia,Drpl is activated and translocates from the cytoplasm to the mitochondrial outer membrane,mediates mitochondrial fission and eliminates damaged mitochondria.Drpl plays the important roles in the pathological processes of ischemic neuronal apoptosis,necrotic apoptosis,and mitophagy.Excessive mitochondria fission or accumulation of damaged mitochondria will aggravate neuronal injury.

Objective To evaluate hernia repair with Onlay (premuscular positioning of the prosthesis) for the treatment of parastomal hernia.Methods In this study 45 patients with parastomal hernia were treated with a tension-free manner of hernia repair in situ by Onlay using prolene mesh between February 2006 and April 2012.There were 24 males and 21 female cases,including 6 recurrent parastomal hernia cases.The average age was (49 ±8) years ranging from 43 to 80.The parastomal defect ranged from 4 cm to 9 cm.Results All operations were successful.There was no hospital death or severe postoperative complications.The mean operating time was (109 ± 23) min (96-148),and the average time of pulling out the gastrointestinal decompression tube was (2.0 ± 2.0) day (12 h-3 d) and the drainage tube was removed after (5.0 ± 2.0) days (4-9 d).The mean postoperative hospitalization was (11 ± 3) days (9-16 d).42 cases achieved primary healing.The serofluid swelling in 7 cases was cured by puncturing and pressing the incision.41 cases were followed-up from 8 to 48 months,and 4 patients suffered from hernia recurrence respestively after 3 months,4 months,4.5 months and 7 months.One recurrent case was healed by conservative therapy and the other three were healed by reoperation.Conclusions Hernia repair in situ with Onlay method for parastomal hernia with prolene mesh was a safe and effective.

Objective To explore the accuracy and practical significance of the 3-dimensional (3D) reconstruction of the liver and the abdominal blood vessels based on the data of 64-slice spiral computerized tomography (64S-SCT). Methods The 2D images of the liver and the abdominal blood vessels were collected after TLC-scanning with 64S-SCT. The 3D images of the liver, hepatic internal duct system and the abdominal blood vessels were reconstructed by the medical image processing system. The volume of the 3D reconstructed liver was compared with that of the actual liver measured by the 64S-SCT, and the portal vein of the reconstructed liver model was compared with that reconstructed by the Mxview workstation based on the 64S-SCT data. Results The 3D models of the liver, hepatic internal duct system and abdominal blood vessels were vivid, and could be revolved and observed at any direction. The spatial relationship among main intrahepatic ducts was clearly displayed. The actual liver volume and the condition of the intrahepatic ducts were accurately demonstrated. The reconstructed liver, the branches of the hepatic artery and portal vein, and the abdominal blood vessels were simultaneously displayed by adjusting the transparency of the liver model. The portal vein of the reconstructed liver model completely matched that reconstructed by the Mxview workstation based on the 64S-SCT data. Conclusions The 3D models of the liver, hepatic internal duct system and abdominal blood vessels reflect the human anatomy structure, and provide reliable virtual organs and vessel system for virtual liver surgery.

BACKGROUNDMatrix metalloproteinase-9 (MMP-9), endostatin (ES) and vascular endothelial growth factor (VEGF) are important angiogenic regulators for many neoplasms. The aim of this study is to judge clinical and prognostic values of detection of serum MMP-9, ES and VEGF in patients with non-small cell lung cancer (NSCLC).
METHODSSerum levels of MMP-9, ES and VEGF were detected in 92 patients with NSCLC, 50 patients with pulmonary benign disease and 52 healthy controls by ELISA method.
RESULTSThe serum levels of MMP-9, ES and VEGF in NSCLC patients were significantly higher than those in patients with pulmonary benign disease and healthy controls (P=0.000, P=0.000, P=0.000). The sensitivity and specificity of serum MMP-9 was 92.51% and 79.10% with a cutoff value of 117.17 μg/L, 88.32% and 74.25% for ES with a cutoff value of 100.31 μg/L, and 83.40% and 75.63% for VEGF with a cutoff value of 380.32 ng/L. Serum MMP-9 and ES levels were significant prognostic factors for lung cancer patients (P=0.0145, P=0.008). The change of serum MMP-9 level after chemotherapy was a useful indicator of prognosis for NSCLC patients (P=0.0322).
CONCLUSIONSThe serum levels of MMP-9, ES and VEGF are significantly increased in patients with NSCLC. They might be used as prognostic parameters in patients with NSCLC.

Objective To analyze the related factors of congestive heart failure (CHF) in elderly female patients. Methods 39 female patients aged over 60-year-old with chronic CHF were divided into two groups according to the cardiac functional grading. Historical features and data were compared between two groups by single factor and multifactorial regression analysis.Results There were differences between two groups in hemoglobin concentration, serum creatinine, incidence of chronic kidney disease and anemia (P<0.01), but no obvious difference between two groups in morbidity of hypertension and diabetes. And it was n by multifactorial regression analysis showed that hemoglobin concentration, serum creatinine, incidence of chronic kidney disease and anemia could not be in regression equation. Conclusion The hemoglobin concentration, serum creatinine, incidence of chronic kidney disease and anemia may associated with degree of congestive heart failure.

BACKGROUNDUroacitides is a group of cell differentiation inducers, which is purified from fresh human urine. Preclinical studies of Uroacitides have showed that cancer cells could be induced to differentiate, and the growth of cancer cells could be inhibited by Uroacitides. The aim of this study is to compare the efficacy and toxicity between Uroacitides combined with NP regimen and NP alone in treatment of advanced non-small cell lung cancer (NSCLC).
METHODSForty-two cases of advanced NSCLC were randomized into Uroacitides+NP and NP groups. NP group: NVB 25mg/m² on days 1 and 8, DDP 75mg/m² on day 1. Uroacitides combined with NP group: Uroacitides of 300mL was given through subclavian catheter daily for 7 days prior to the NP chemotherapy, then concurrently with NP regimen for 2 cycles, except the days of administration of chemotherapy.
RESULTSIn the Uroacitides+NP group, the overall response rate was 44.4%, and 20.0% in the NP group (P > 0.05). The median survival time was 9 months in the Uroacitides+NP group and 6 months in the NP group (P=0.0287). The main toxicities were myelosuppression, gastrointestinal reaction and alopecia, and there was no significant difference in incidences of toxicities between the two groups (P > 0.05).
CONCLUSIONSUroacitides combined with NP regimen shows a good curative effect and low toxicity, and may significantly prolong the median survival time for advanced NSCLC.

BACKGROUNDTo evaluate the efficacy, side-effects, median survival duration and survival rate of vinorelbine (NVB) combined with cisplatin (DDP) in the treatment of non-small cell lung cancer (NSCLC).
METHODSA total of 220 patients with inoperable NSCLC received NVB and DDP combined chemotherapy: NVB 25-30 mg/(m²*d) on days 1 and 5 (or 8), DDP 60-80 mg/(m²*d) on day 2. The schedule was repeated every 28 days. The efficacy and side-effects were analysed and followed-up after at least two cycles of chemotherapy.
RESULTSThe overall response rate (CR+PR) was 30.9% (68/220). The response rate was 31.3% (51/163) in initial treatment group, and 29.8% (17/57) in retreatment group. The median survival duration was 8.3 months. The 1-, 2- and 3-year survival rates were 39.23%, 19.31% and 6.32%, respectively. The main side-effects were myelosuppression and digestive tract reactions.
CONCLUSIONSVinorelbine plus cisplatin is an effective and well-tolerated regimen for non small cell lung cancer and myelosuppression is its dose-limiting toxicity.
