Objective To study the combination effectof curcumin and γray on the activity of human lung carcinoma NCI-H460 cells and explore the sensitization of curcumin to γray.Methods The NCI-H460 cells proliferation were detected by MTT,the cell cycle and apoptosis by flow cytometry.The expression of Bcl-2 and Bax were detected by Western Blot and the NF-κB gene expression by RT-PCR.In addition,the mice model of lung cancer was randomly divided into 4 groups:control group,curcumin group,γ ray group and combination group.After 28 days,the tumor volume was measured.Results The proliferation and cell cycle of NCI-H460 cells were inhibited and the apoptosis was increased in combination group.In addition,compared with curcumin group or γray group,the expression of Bcl-2 was inhibited,but the expression of Bax was increased and the mRNA expression of NF-KB was inhibited in combination group(all P＜0.05).Also in combination group the tumor volume was significantly inhibited compared with curcumin group or γ ray group(all P＜0.05).Conclusion Curcumin might induce the radiosensitivity of Human Lung Carcinoma NCI-H460 cells through the pathway.

Osteoporosis is a common metabolic bone disease in the aging population society. The incidence is increasing during these years. Elderly people especially postmenopausal women are of greatest susceptibility. Fracture and other complications caused by osteoporosis may affect patients' life span and the quality of life. It also increased medical costs. The principles of managing osteoporosis are understanding the risk factors and susceptible population; appropriate evaluating bone mass and multidisciplinary approach. The present paper reviewed the update of epidemiology, pathophysiology, risk factors, evaluation methods and management of this disease.

Advances in hepatic surgical technique,perioperative care and improvements in patient selection criteria have increased the number of patients who could undergo major or extended hepatectomy with curative intent.Posthepatectomy liver failure (PHLF) is one of the most serious complications after liver resection.Different risk factors are related to the occurrence of PHLF,among surgery-related factors,massive bleeding and remnant liver volume were related to higher frequency of PHLF.The presence of diabetes and liver disease such as cirrhosis,cholestasis,steatosis had been involved with the occurrence of PHLF.So far there is no good method for the treatment of PHLF,so prevention is very important.

Objective To determine the effects of lensspecific overexpression of OSM on the eye development. Methods A truncated mouse OSM cDNA (661 bp) was linked to the ?A-crystallin promoter. Transgenic mice were characterized by routine histological and immunohistochemical techiniques. TUNEL assays were used to detect cell death. The mRNA expression of caspase-3 was detected by in situ hybridization, Rabbit anti-cleavage caspase-3 antibody was used to detect active capase-3. Results At embryonic day (E) 14.5 and 17.5, expression of the OSM transgenic protein was detected specifically in lens fiber cells. The onset of retinal degeneration in the mid portion of the transgenic retinae was observed started from E17.5. By the time of birth 50% or more of the retinal cells were missing. The OSM transgenic retinal cells underwent apoptosis indicated by TUNEL assays. Most strikingly, activation of caspase-3 protein were observed throughout the transgenic retinas. Conclusions Lens-specific overexpression of OSM activate caspase-3, leading to abnormal eye development, apoptosis and widespread retinal degeneration.
