ABSTRACT
Objective To investigate the clinical features of osteonecrosis of the knee (ONK) in patients with systemic lupus erythematosus (SLE).Methods A retrospective chart review was conducted to identify patients of SLE with ONK.The clinical characteristics of these patients were analyzed.Results Between 2008 and 2013,eighty-one patients with SLE were analyzed in the 210th Hospital of People's Liberation Army.Eleven of these patients were diagnosed as ONK.All of these ONK patients were female.The age of onset ranged from 19-57 (36±13) years.The disease duration ranged from 4.5-31.0 (13±6) years.The local clinical symptom included knee swelling with pain in 5 cases,only pain with no swelling in 1 patient,no symptoms in 5 patients.All patients were with aseptic necrosis of the femoral head.For laboratory examination,7 patients had elevated triglyceride lipids in blood.Three of 7 patients accompanied with cholesterol level increased.Total cumulative dosage of oral corticosteroids was (66 824±27 328) mg.Conclusion ONK in patients of SLE is common and the majority of them have impaired renal function and elevated blood lipids,as well as long-term glucocortico-steroid therapy.
ABSTRACT
Aiming at the characteristics of combat readiness medical teams in military hospital,this paper designs a management system for hospital combat readiness.It can effectively manage such work in medical team as medical equipment,medicine,consumable,personnel,preparation,training,etc.It not only improves the equipment flow in storehouse but enhances the work efficiency.
ABSTRACT
AIM To observe the expression of inducible nitric ox ide synthase (iNOS) in the rats' hippocampus of kainic acid (KA) induced-seizur es and the effect of L-arginine(L-Arg) or L-nitroarginine(L- NNA) chronic intervention before KA. METHODS The expression of iN OS mRNA by RT-PCR and behaviour were observed after administration of convulsan t dose of KA (10 mg?kg -1 ) and pretreatment with NO predecessor (L-Ar g, 40 mg?kg -1 ) or a inhibitor of NOS(L-NNA, 50 mg?kg -1 ) befo re KA. RESULTS The time-dependent seizures were induced on rats after giving KA, and were improved and serious in the animals with L-NNA pr etreatment, but they were alleviated by L-Arg pretreatment before KA. Compa red with control, iNOS mRNA expression was feebly at KA 3 h, continuative improv ement accompanying KA time prolonged, and it was markedly enhanced at KA 24 h. I t couldn't be examined at KA 2 d or 3 d, and was obviously improved at KA 7 d a gain. iNOS mRNA appeared weak in the rats hippocampus with L-Arg pretreatme nt after KA 1 h, whereas it wasn't found in L-NNA pretreatment animals. CONCLUSION iNOS mRNA expression appeared in the hippocampus of seizu re rats at a few time after KA, and L-Arg chronic intervention before KA ha s a little effect on it.
ABSTRACT
AIM To explore the role of nitric oxide (NO) mediators in seizure behavior and the related expression of interlukin 6(IL 6). METHODS The IL 6 immunoreactivity (IL 6 ir) and behaviour were observed in kainic acid (KA) induced seizure following pretreatment with L nitroarginine( L NNA), a inhibitor of nitric oxide synthase(NOS), or the same number of moles of L arginine( L Arg). RESULTS The results showed that time dependent seizures were induced on animals after administration of KA (10 mg?kg -1 ), accompanied by the immediate enhancement of IL 6 ir in hippocampal structure, piriform area and cortex. The behaviors of rats were not markedly altered by chronic pretreatment with L NNA (50 mg?kg -1 ) or L Arg (40 mg?kg -1 ). However, after the administration of KA, the seizure behaviors were obviously different in the group of L NNA and L Arg respectively. Seizure was agrevated in the animals with L NNA pretreatment and many rats died at KA 3 hours, whereas seizure was alleviated after KA in the group of L Arg. IL 6 expression was apparently up regulated in some brain areas such as hippocampus in the group of KA pretreated with L NNA, but opposite effects appeared in the group pretreated with L Arg before KA injection. CONCLUSION These results indicate that endogenous NO mediators may alleviate the seizure behaviors and may down regulated the early expression of IL 6 in KA challenged seizure, but it the mechanism of the early expression of IL 6 with the homeostasis of endogenous NO mediator merits further study.nismoftheearlyexpressionofIL 6withthehome
