Apoptosis is an essential factor in keeping homeostasis of the organism. Apoptosis is regulated by a series of cytokines. Bcl-2 family proteins are key regulators of apoptosis. The Bcl-2 family includes both anti- and pro-apoptotic proteins with opposing biological functions. Their interaction regulates the transmission of the apoptosis signal. High expression of anti-apoptotic members such as Bcl-2 and Bcl-xL are commonly found in human cancers. In recent years, following the disclosing of the crystal structures of Bcl-2 family proteins, researchers have paid attention to the development of the small molecule inhibitors of Bcl-2 family proteins. This article reviews the progress in this field from the view of drug design.

Researches on the testicular dysgenesis syndrome (TDS) have flourished in the recent decade, and a widely accepted view on its pathogenesis is that environmental endocrine disrupting chemicals (EDCs) act on Leydig cells and/or testicular Sertoli cells, resulting in abnormal development of the testis and leading to the symptoms of TDS. Molecular biological studies suggest a correlation of TDS etiology with insulin-like factor 3 (INSL-3), androgen receptor (AR), P27kip, WT-1 and Müllerian inhibiting substance (MIS). This review focuses on the progress in current researches on the etiology and mechanism of TDS.

pH and temperature sensitive biodegradable block copolymers are some macromolecules connected by biodegradable materials and pH sensitive monomers according to a certain sequence, or biodegradable polyesters polymerized themselves. On the basis of pertinent documents, the development of pH and temperature sensitive biodegradable block copolymers was introduced, involving their mechanism of action and potential application. PH and temperature sensitive biodegradable block copolymers could control the drug release rate freely, avoiding burst effect. Besides, the biocompatibility of these biodegradable materials is also excellent. So the use of pH and temperature sensitive biodegradable block copolymers as biodegradable drug delivery devices has attracted considerable interest in the intelligent drug delivery system.

OBJECTIVETo investigate the effects of free and pedicled thoracodorsal artery perforator (TDAP) flaps for repairing skin and soft tissue defects in limbs, neck, axillary and shoulder.

METHODSFrom October 2009 to Auguest 2011, 16 TDAP flaps were used to repair skin and tissue defects. Among them, five ipsilateral pedicled flaps were used to repair wounds in neck, axillary and shoulder. 11 free TDAP flaps were used to repair the wounds with bone or tendon exposure. In 12 cases, the flaps were pedicled with thoracodorsal artery and vein-lateral branches-perforators, in 4 cases, pedicled with thoracodorsal artery and vein-serratus anterior muscular branches-perforators. The deep fascia, the latissimus dorsi and thoracodorsal nerve were not included in all flaps. The flaps size ranged from 10 cm x 5 cm to 26 cm x 10 cm.

RESULTSAll 16 flaps survived completely with primary healing both at donor site and recipent area. After a follow-up of 3 to 24 months, all flaps gained good texture and appearance. Only linear scar was left at donor area. The shoulder could move freely.

CONCLUSIONSTDAP flap has good texture, long vascular pedicle,and reliable blood supply, leaving less morbidity at donor site. The latissimus dorsi and thoracodorsal nerve are also preserved. The pedicled TDAP flap is an ideal flap for repairing the ipsilateral skin and soft tissue defects of the neck, shoulder, axillary. The free TDAP flap is suited for repairing skin and soft tissue defects of the extremities.

OBJECTIVETo establish an porcine model of whole pancreaticoduodenal transplantation with portal venous drainage and enteric drainage for ensuring physiologically normal function without hyperinsulinemia and reducing postoperative complications.

METHODSTwenty sichuan native outbreding white pigs weighing 25-30 kg were divided equally into two groups to serve as the donors and recipients. Cooling of the grafts was accomplished with in situ flush with 4 degrees C UW preservation solution via an aortic cannula. A whole pancreatoduodenal graft with the segment of abdominal aorta and the portal vein was harvested from the donor pigs. Type I diabetes model was established by complete removal of the recipient pancreas. The whole pancreatoduodenal graft was preserved and shaped in UW solution, and the subphrenic abdominal aorta of the recipient was joined with the donor abdominal aorta via a side-to-end anastomosis, and venous reflux was reconstructed between the donor portal vein and the recipient superior mesenteric vein. Side-to-side intestinal anastomosis was performed between the donor duodenum and the recipient jejunum.

RESULTSTen pancreaticoduodenal transplantations (PVE+ED style) were done, and pancreatic graft thrombosis and embolism occurred only in 1 pig 6 days after transplantation.

CONCLUSIONThe model of whole pancreaticoduodenal transplantation with portal venous drainage and enteric drainage is stable and reliable.

OBJECTIVETo explore the influence of oxidized high-density lipoprotein (oxHDL) on the maturation and migration of bone marrow-derived dendritic cells (BMDCs) from C57BL/6J mice.

METHODSThe C57BL/6J mice bone marrow cell suspension was prepared and purified. Recombinant granulocyte-macrophage colony-stimulating factor (rmGM-CSF) and recombinant interleukin-4 (rmIL-4) were used to promote monocytes to differentiate and suppress lymphocytes. Then 50 microg/mL oxHDL was added to stimulate BMDCs, using 50 microg/mL high-density lipoprotein (HDL) as homologous protein control, PBS as negative control, and 1 microg/mL lipopolysaccharide (LPS) as positive control. The CD86 and MHCII expression rates were detected with fluorescence-activated cell sorting (FACS). Liquid scintillation counting (LSC) was used in mixed lymphocyte reactions (MLRs) to reflect the ability of BMDCs in stimulating the proliferation of homologous T cells. Levels of cytokines IL-12 and IL-10 were detected by ELISA. The cell migration was evaluated with the transwell system.

RESULTSCompared with PBS group, the expressions of CD86 and MHCII, counts per minute of MLRs, secretion of IL-12 and IL-10, and number of migrated cells in oxHDL group and LPS group significantly increased (all P<0.05), while the increment was less in oxHDL group than LPS group. The number of migrated cells in oxHDL group was about twice of that in HDL group.

CONCLUSIONOxHDL may promote the maturation and migration of BMDCs in vitro.
