TNF related apoptosis inducing ligand (TRAIL) is a new identified member of TNF family, which selectively kills a broad spectrum of tumor cells, but nontoxic to most normal cells. TRAIL triggers tumor cell apoptosis via death receptor DR4 and DR5 anchored in the cell surface, which is mediated through intracellular induced apoptosis proteins. The major pathway of its action proceeds through the formation of DSIC and activation of caspase8. The apoptotic processes follow two signal pathways, namely the mitochondrial independent activation of caspase3, and mitochondrial dependent apoptosis through the cleavage of BID by caspase8, the release of cytochrome C, the formation of apoptosome, and activation of caspase9 and the downstream apoptosis. In previous researches, it is shown that nontagged TRAIL proved to be noncytotoxic to hepatocytes in monkeys and chimpanzees and to human normal hepatocytes. Thus, the nontagged TRAIL has attracted great attention in recent years as a promising anti cancer reagent.

Recently accumulating evidence has shown that innate immunity recognition of invading pathogens can be attributed mainly to the Toll-like receptor (TLR) family.TLR signaling can induce the production of proinflammatory cytokines and upregulate expression of costimulatory molecules to provoke rapid activation of innate immuniry. Activated innate immunity subsequently leads to effective adaptive immunity. It, thereby, activites not only innate but ultimately also adaptive immunity. It can mediate activation of many kinds of cells, such as immune cells, hepatocytes et al. Upon binding to its respective ligands, TLR can activate signal transduction cascades leading to activation of transcription factors and protein kinases such as NF-?B and MAPK, and expression of immune response genes. Besides,TLR family may be involved in the pathogenesis of inflammation via recognition of host products. Inhibition of TLR action may work as anti-inflammatory drugs, and possibly also as agents to treat autoimmune diseases.Thus,the increasing understanding of TLR system could be the basis for treating a variety of pathological conditions.

Objective To investigate the clinical and electromyographic features of peripheral nerve involvement in MS. Methods The clinical and electromyographic (EMG) data of 29 MS patients were evaluated retrospectively.Results 18 (62.1%) patients showed clinical and/or electromyographic abnormalities of peripheral nerves. The clinical symptoms included extremity numbness in 16 cases (88.9%), limb inertia in 11 cases (61.1%), radicular pain in 5 cases (27.8%), autonomic nerve disorder and dysphagia in few patients. Signs included decrease of tendon reflex in 11 cases (61.1%), periphery or root form hypoesthesia in 9 cases (50%), muscle weakness in 7 cases (38.9%), myatrophy in 4 cases (22.2%), and reduced pharyngeal reflex in 1 case (5.6%). There was no difference in age of onset, course of disease, neurologic impairment and prognosis between the patients accompanied with peripheral neuropathy and the patients without peripheral neuropathy. The electromyographic abnormalities included spontaneous potential in 4 cases (13.8%), increased motor unit potential in 8 cases (27.6%), slow MCV in 15 cases (51.7%), slow SCV in 13 cases (44.8%), low amplitude in 9 cases (31.1%), and prolonged distal latency in 5 cases (17.2%). The neuropathies improved by treatment with corticosteroid in the all patients except one.Conclusions Some MS patients may accompany with peripheral nerve abnormalities, which may improve with the recovery of MS. EMG is useful to evaluale the site and degree of peripheral nerve damage.

Objective　To investigate the relationship of proximal femur geometry and hip fracture in elderly women. 　Methods　 We compared proximal femur measurements made from the uninvolved hip of 48 plane anteroposterior pelvis radiographs of elderly women without fracture to those of the contralateral hip in a group of 43 cases with hip fracture. Measurements of Singh index, head diameter(HD), neck diameter(ND), femoral neck length(NL), neck shaft angle(NSA) and cortical thinckness of proximal femur were analyzed. 　Results　 The cortical thickness of proximal femur in hip fracture and without hip fracture groups was (10.9±3.1) mm and (13.2±2.9) mm, and the Singh index below Ⅲ° was 86.05% and 66.67%, respectively. No difference in HD,ND,NL and NSA could be demonstrated.　Conclusions　 Singh index and cortical thickness of proximal femur may be used to predict the occurrence of the hip fracture in elderly women.
