1.Challenges in Drug Discovery for Thiazolidinedione Substitute.
Acta Pharmaceutica Sinica 2011;1(3):137-142
Thiazolidinedione (TZD) is a powerful insulin sensitizer in the treatment of type 2 diabetes. It acts as a ligand to the nuclear receptor PPARγ (peroxisome proliferator-activated receptor-gamma) and induces transcription of PPARγ responsive genes. TZD controls lipid synthesis and storage in adipose tissue, liver and many other tissues through PPARγ. Derivatives of TZD, such as rosiglitazone (Avandia) and pioglitazone (Actos), are more powerful than metformin or berberine in insulin sensitization. Although they have common side effects such as weight gain and edema, these did not influence the side effects in general. However, recent findings of risk for congestive heart failure and bladder cancer have indeed significantly impaired their future in many countries. European countries have prohibited those drugs and in 2011, US will terminate application of rosiglitazone in clinics and hospitals. The multiple country actions may mark the end of TZD era. As a result, there is a strong demand for identification of TZD substitute in the treatment of type 2 diabetes. In this regard, literature about PPARγ ligands and potential TZD substitute are reviewed in this article. Histone deacetylase (HDAC) inhibitor is emphasized as a new class of insulin sensitizer here. Regulators of SIRT1, CREB, NO, p38, ERK and Cdk5 are discussed in the activation of PPARγ.

Acta Anatomica Sinica 1954;0(02):-
WGA-HRP was injected into the inferior colliculus in the rat in order to study the non-auditorial afferents of the inferior colliculus. In the diencephalon and truncus encephali, retrograde labeling was observed in many non-auditorial regions: bilateral (with contralateral predominance) cuneate nucleus, gracile nucleus, nucleus of spinal tract of trigeminal nerve, nucleus medullae oblongatae centralis dorsalis; bilateral (with homolateral predominance) locus ceruleus, nucleus reticularis pontis oralis, laterodorsal tegmental nucleus, substantia nigra, sub-parafascicular nucleus, perifornical nucleus; bilateral medial parabrachial nucleus, deep tegmental nucleus of midbrain, lateral hypothalamic area; homolateral deep layer of superior colliculus, zona incerta; contralateral nucleus of solitary tract; and posteromedian septum, central tegmental nucleus, dorsal nucleus of the raphe. The afferent neurons from cuneate nucleus, gracile nucleus, nucleus of spinal tract of trigeminal nerve, nucleus of solitary tract mainly located below the level of obex. The results mentioned above suggested that the inferior colliculus is not only an auditorial relay nucleus, but also a complex body which is of different functions.

Objective To explore the effect on effect of combined use of Y27632 (ROCK II inhibitor)and TDZD-8(GSK-3β inhibitor)on axonal regeneration of dorsal root ganglion (DRG) neurons in neogenetic rats. Methods All the thoracolumbar DRGs of two neogenetic Sprague-Dawley (SD)rats(<5 days)were harvested under the stereopsis raicrostat,and then the DRG neurons were cultured,purified and indentified.Fifteen adult female SD rats were randomly divided into three groups,ie,complete paraplegia group(5 rats),sham operation control group(5 rats)and normal group(5 rats)respectively.The T8-10 spinal cord extracts (SCEs) were harvested in the complete paraplegia group,sham operation control group and normal group respectively at day 7 after spinal cord injury.The experiment was divided into group A(DRG neurons + PBS),group B(DRG neurons + complete paralysis SCE),group C(DRG neurons + complete paralysis SCE + different concentration Y27632),group D(DRG neurons + complete paralysis SCE + different concentration TDZD-8)and group E(DRG neurons + complete paralysis SCE + proper concentration Y27632 and TDZD-8).The average axonal length and expression intensity of Tubulin βⅢ at distal end of neuronal axons were observed after two days of co-culture respectively in intro. Results (1)The average axonal length and expression intensity of Tubulin βⅢ at axon shaft and growth cone in the group B were significantly shorter and weaker than that in the group A,with statistical difference.(2)In the group C,the average axonal length and expression intensity of Tubulln βⅢ at axon shaft and growth cone in 5-10 μmol/L Y27632 treatment groups were more than that in the group B but lower than that in the group A.The average axonal length and expression intensity of Tubuhn βⅢ at axon shaft and growth cone in 20-50 μmol/L Y27632 treatment group were longer and stronger than that in the group A and the group B,especially the group B.Among different concentration Y27632 treatment groups,there was a longest average axonal length and strongest expression intensity of Tubulin βⅢ in 30 μmol/L treatment group.(3) In the group D,there was a longer average axonal length in 0.5-3 μmol/L TDZD-8 treatment group than that in the group A and the group B,with the longeat average axonal length in l μmool/L TDZD-8 treatment group.In 5-25 μmol/L TDZD-8 treatment groups,the average axonal length showed no difference compared with the group B but wns shorter than that in the group A.In all different concentration TDZD-8 treatment groups,the expression intensity of Tubulin βⅢ at axon shaft and growth cone was significantly stronger than that in the groups A and B.(4) In the group E,although the average axonal length was increased in the group E,there was no statisilcal difference compared with the group A,30 μmol/L Y27632 treatment group and l μmol/L TDZD-8treatment group.There was a significantly longer average axonal length in the group E than it in the group B and the expression intensity of Tubulin βⅢ at axon shaft and growth cone was stronger in the group E compared to the group A,30 μmol/L Y27632 treatment group and l μmol/L TDZD-8 treatment group.Conclusion The complete paralysis SCEs obviously inhibits DRG axonal growth,induces axonal retraction and growth cone collapse.High concentration of Y27632 can more obviously promote the axon growth compared with the low concentration,while the low concentration of TDZD-8 can obviously promote the axon growth.Combined use of appropriate concentration of TDZD-8 and Y27632 can promote the axon growth and induce the axons branching,as facilitates the formation of the axon circuit.

Objective To study the clinical feature, diagnossis and therapy of open spinal cord injury. Methods A retrospective study was performed in 15 patients with open spinal cord injury including 14 males and one female, at age range of 15-46 years (mean 23 years). There were two patients with open cervical spinal cord injury, 11 with open thoracic spinal cord injury and two with open lumbar spinal cord injury. Injury causes included sharp knife injury in 12 patients, firearm injury in two and stick stabbing in one. According to ASIA scale, there was one patient at Grade A, two at Grade B, seven at Grade C, four at Grade D and one at Grade E preoperatively. Foreign bodies were found in the wound in four patients. There were three patients combined with spinous process fracture, eight with vertebral plate fracture and five with vertebral body fractures. All 15 patients were treated by emergency management including vertical canal exploration, hematoma debridement or foreign body removal. Results Postoperative complications included cerebrospinal fluid leakage in two patients and wound infection ( without spinal cord infection) in one. There were different degrees of neural functional recovery in five patients. The post-operation ASIA scale: one patient at Grade A, three at Grade C, 10 at Grade D and one at Grade E,with no patient at Grade B. Conclusions For open spinal cord injury, emergency operation is necessary under adequate preoperative preparation. Preoperative identification of foreign bodies, exploration and decompression are beneficial to spinal cord function recovery and reduction of the incidence rate of postoperative complications like infection or hemorrhage.
