Objective To investigate the effect of integrin-linked kinase (ILK) on inducing mesenchymal stem cells (MSCs) to neuron stem-like cell in vitro. Methods MSCs isolated from umbilical cord were transfected with plasmid DNA encoding green fluorescent protein (GFP) and GFP-fusion ILK, wild and mutant, respectively; and cultured in serum-free media with basic fibroblast growth factor, epidermal growth factor and B27. It was assessed with the proliferative activity and the efficiency of differentiation into neural stem-like cell. Results MSCs transfected with GFP-fusion wild ILK expressed ILK and kinase-dead mutant ILK stably. The activity of proliferation increased and more of them differentiated into neural stem-like cell, which express CD133 and Nestin validated by PCR and Western blotting, and more of wild than of mutant. Conclusion Integrin-linked kinase may play a positive role in MSC differentiation into neural stem-like cell, which may associate with the activity of kinase.

Objective To study the characteristics of mismatch negativity(MMN) in patients with depression.Methods MMN was recorded from 31 patients with depression and 28 age-matched controls. Results Compared with the controls, the patients with depression had prolonged latency ([189?22] ms vs [206?26] ms, P

Objective To explore the imageologic characteristics of pelvic fractures with artery injuries and the treatment methods for embolization of arteries.Methods From January 1999 to June 2005,60 cases(42 males and 18 females)aged 21-52 years(average 34.5 years)with pelvic fractures and unsteady blood dynamics were admitted into our hospital.There were 32 cases with traffic injury,13 with crushing injury,nine with fall injury and six with other injuries.The mean injury severity score was 39?16(16-66).All cases were hypetensive with systolic blood pressure less than 90 mm Hg on the arrival.Routine X-ray examination of dorsaventral,debouch and porch of pelvis was performed.The aver- age amount of blood transfusion was 2 886 ml.All cases underwent iliac artery angiography and pelvic ar- teriography.Results X-ray examination of pelvic fractures showed posterior pelvic fracture in 25 ca- ses,with 64 branches of blood vessels injured;anterior pelvic fracture in 13,with 17 branches of blood vessels injured;acetabular fracture in six,with 12 branches of blood vessels injured;and combined pel- vic fracture in 16,with 36 branches of blood vessels injured.Three cases died,with mortality rate of 5%.One case with common arterial thrombosis was treated with artificial blood vessel transplantation, four cases with external iliac artery injuries including one with artery rupture were treated with prosthesis, and among the three cases with external iliac artery thrombosis,one was treated with dislodgment of thrombosis,one treated with recanalization of thrombolysis and one did not give any treatment.Fifty cases with injury and bleeding of internal iliac artery and its branches were treated with arterial embolization. Five cases showed no obvious injury.Conclusions The types of artery injuries can be predicted through X-ray of pelvic fracture.Posterior pelvic fracture may easily cause injury to superior gluteal arter- ies,iliac lumber arteries,and lateral sacral arteries.While anterior pelvic fracture will cause injury to obturator arteries.Superior gluteal artery is susceptible to injury.Embolization of injured arteries and an- astomosis are preferred treatment for pelvic arterial disruptions.

Abstract: - （ ） ， Work related musculoskeletal disorders WMSDs are common occupational diseases in construction workers which have a high prevalence rate and involve a large number of construction workers. WMSDs affect daily work and quality of life of ， patients leading to absenteeism and burden. The main body parts of construction workers suffering from WMSDs are lower back/ ， ， ， ， ， waist neck shoulder knee elbow and hand/wrist and most of the patients are complicated in multiple sites. The prevalence ， of WMSDs varies by site with the lower back/waist being the most common sites. The influencing factors of WMSDs in （ ， ， ， ， ， construction workers mainly include individual factors age years of work gender smoking status sleep habits physical ， ）， （ ， ， ， fitness and physical exercise etc. occupational factors work load job type working posture work organization and ， ） management working environment and social psychological factors. The incidence of WMSDs is the result of multiple factors. ， ， Therefore tertiary prevention is the key to the prevention and control of WMSDs especially the etiological prevention. Chinese ， construction industry is in the period of rapid development and the demand of construction workers is large. It is urgent to carry out epidemiological and intervention studies on WMSDs for construction workers to guide the formulation of relevant guidelines and measures for prevention and control of WMSDs.

Complex genetic variation has been known to occur during the transmission of human enterovirus (HEV), and the HEV virulence and pathogenicity enhanced by genetic recombination also pose a serious threat to human health. In recent years, the interest in recombination mechanism of genetic plasticity has been renewed with the emergence of pathogenic recombinant circulating vaccine-derived polioviruses, which were implicated in poliomyelitis outbreaks in several regions of the world with insufficient vaccination coverage. This paper reviews recent research progress in HEV genome, including evolutionary characteristics, recombination types, and in vitro recombinant construction.

0.05). Conclusion There is abnormal thyroid function in patients with anorexia nervosa. Most of the patients with anorexia nervosa are individuals with low T3 syndrome, rather than hypothyroid. Since this syndrome is reversible, thyroxine is not necessary during the treatment.

0.5 cm or beneficial anatomical vari- ations displayed on MRCP,were obviously improved and there were no significantly different among the 4 types hilar eholangiocarcinoma.Conclusion MRCP could accurately make the preoperative diagnosis and type of hilar cholangiocarcinoma; the image of second branch of bile duct and the variation of the confluence of hepatic hilar displayed on MRCP has great clinical significance for operative regimes of hilar cholangiocar- cinoma,especially for typeⅣ.It does benefit not only to improve the resection and radical rate of some hilar cholangiocarcinomas, but also to select suitable method of biliary enteric anastomosis and avoid injuring the bile duct in operation.
