This study was aimed to investigate the biological behavior of annonaceous acetogenin mimic AA005 in various kinds of leukemia cells and further elaborated its possible mechanisms in acute promyelocytic leukemia (APL) cell line NB4. The proliferative inhibition of leukemia cells was measured by CCK-8 method. Cell death was determined by trypan blue. Cell morphological features of NB4 treated with AA005 were examined by microscopy after Wright's staining. The form of cell death was measured by flow cytometry. Proteins PARP-1 and caspase-3 were detected by Western blot. Flow cytometry was used to detect the cell cycle arrest induced by AA005 of low concentration. The results showed that AA005 (> 200 nmol/L) significantly inhibited proliferation of all tested leukemia cell lines in a concentration-dependent manner. The vast majority of cells went to die after leukemia cell lines of NB4, U937 and K562 were treated with different concentration of AA005 for 48 h. Typical morphologic changes significantly appeared in NB4 cells after AA005 treatment. AA005 almost simultaneously induced early apoptosis and late apoptosis. The little cleavage of PARP-1 and activation of caspase-3 happened in AA005-induced cell death, and caspase-3 inhibitor Z-VAD-fmk could not block the cell death. The non-toxic concentrations of AA005 (< 200 nmol/L) caused NB4 cells G(2)/M-phase arrest. It is concluded that annonaceous acetogenin mimic AA005 induces significant proliferative inhibition of various leukemia cell lines in a concentration-dependent manner, which may be associated with cell death and G(2)/M-phase arrest induced by AA005.

Objective To analyze the factors that influence the survival condition during the first year after hepatectomy in patients with hepatocellular carcinoma (HCC). Methods Five hundred twentyeight HCC cases undergoing hepatectomy were included from January 1997 to December 2008.The factors and survival outcomes in these patients were analyzed. Results There were 302 patients dying during a medium follow-up of 35 months and 1-year cumulative survival was 85%.The causes of death during first year were tumor recurrence (78.1%,75/96) and liver dyscompensation ( 19.8%,19/96).By Cox regression analysis,tumor size ≥5 cm (P =0.047 ),vascular invasion ( P =0.018),histologic moderately and poorly differentiation ( P =0.001 ) and pathologically positive margin ( P =0.004 ) were significantly associated with tumor recurrence,and portal hypertension was an independent factor for patients dying from liver dysfunction ( P =0.001 ).Positive tumor margin was the most important factor associated with postoperative death within one year (59.3%,60/96). Conclusions During the first year after HCC resection,tumor recurrence and liver dysfunction are main factors influencing HCC patients' survival,nonR0 resection is the main factor causing tumor recurrence,and portal hypertension is an independent factor for patients dying of liver dyscompensation.

OBJECTIVETo summarize the experiences and advantages of laparoendoscopic single-site (LESS) surgery for neonatal intestinal atresia and stenosis.
METHODSTwenty patients of neonatal intestinal atresia and stenosis were treated with LESS procedure in Huai'an Women and Children's Hospital of Jiangsu Province between October 2010 and April 2012. The clinical data were retrospectively analyzed.
RESULTSAmong these patients, 13 were male, 7 were female. Age at admission ranged from 10 min to 1 d. Four cases were premature, and 3 were born with low birth weight (<2500 g). One was diagnosed with duodenal atresia, 1 with duodenal stenosis, 9 with jejunal atresia, 2 with jejunal stenosis, and 7 with ileal atresia. Laparoscopic exploration was performed in all the cases by transumbilical procedure, the proximal and distal ends were exteriorized from the umbilical port site for anastomosis. Twenty neonates with intestinal atresia and stenosis were performed using this new minimally invasive approach, with no cases converted to open operation or standard laparoscopy. The operative time was 35-60 (mean, 40) min. The intraoperative bleeding was 3-5 ml. Two cases were given up treatment by their parents on the second postoperative day. For the other 18 patients, oral intake started on postoperative day 5-10 (mean, 7), and discharged from hospital on the postoperative day 10-20 (mean, 13). The follow up ranged from 1 to 11 months, during which 1 case died, 3 cases were managed with conservative treatment for diarrhea or malnutrition. The other 14 cases grew up healthily.
CONCLUSIONThe technique of LESS in the treatment of neonatal atresia and stenosis is simple and the outcomes are satisfactory.

Objective To evaluate the solute clearance characteristics of REXEEDTM series dialyzers during high-flux dialysis, and explore the care characteristics. Methods A randomized crossover study of 3×3 Latin square was designed based on different dialyzers. Eighteen patients with regular hemodialysis underwent dialysis with REXEEDTM-15AC dialyzer, REXEEDTM-15UC dialyzer and controlled APS-15U dialyzer, respectively. Blood samples were obtained from the blood flow entrance and exit of dialyzers, levels of urea nitrogen, creatinine, phosphate and β2-microglobulin were detected, and solute clearance rates were calculated. Before and after the third dialysis with each dialyzer, blood samples were obtained to measure the levels of urea nitrogen and creatinine, and the rates of decrease were calculated. The vital signs of each patient were intensively observed, and the venous pressure and transmembrane pressure were monitored from the dialyzers. Results The urea nitrogen clearance rates of REXEEDTM-15AC dialyzer and REXEEDTM-15UC dialyzer were significantly higher than that of APS-15U dialyzer (P<0.05). The creatinine clearance rate of REXEEDTM-15AC dialyzer was significantly higher than that of APS-15U dialyzer(P<0.05). There was no significant difference in the rate of decrease in blood urea nitrogen among different dialyzers of the same patient(>65 % for all patients). The vital signs were stable with no adverse events during dialysis, and there was no abnormal findings in laboratory security parameters. Conclusion REXEEDTM series dialyzers are effective and safe for clinical application. Great importance should be attached to the complaints from patients during dialysis. For those with less ultrafiltration, fluid as well as uhrafiltration should be supplemented to increase the transmembrane pressure.
