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.

Twenty five new beta-aminoalcohols containing nabumetone moiety were prepared via the reduction of potassium borohydride with a convenient and efficient procedure, starting from beta-aminoketones that have been synthesized by our group. Their chemical structures were determined by IR, MS, 1H NMR, 13C NMR, HR-MS and antidiabetic activities were screened in vitro. Preliminary results revealed that the antidiabetic activity of most beta-aminoalcohols were better than that of the corresponding beta-aminoketones. Although most compounds showed weak antidiabetic activity, the alpha-glucosidase inhibitory activity of compounds 5hd(1) and 5id(2) reached 74.37% and 90.15%, respectively, which were superior to the positive control. The relative peroxisome proliferator-activated receptor response element (PPRE) activity of five compounds were more than 60%, among them compound 5ca possessed the highest activity (112.59%). As lead molecules of antidiabetic agents, compounds 5hd(1), 5id(2) and 5ca deserve further study.
