Objective To explore the caring ability and demands of the primary caregivers of stroke patients in community. Methods Seventeen patients of stroke in community participated in the semi-structure interviews. Data were analyzed by Colaizzi phenomenological procedure. Results The lack of ability of the primary caregivers to take care of, mainly reflected inthe lack of professional knowledge of the disease, lack of basic skills and medication blindness. The factors that affected the ability of the primary caregiversto take care ofwere health status and psychological status of the caregivers, duration of illness of patients, coordination degree of patients and financial burden. The caring demands of the caregivers mainly focused on the following areas: professional medical support, economic support, daily care service, and spiritual support services. Conclusions The government and community health service centers should pay more attention tothe rehabilitation of stroke patients in community, and help them to solvepractical problemsactively, meet the care needs, and improve their self-care ability, so as to improve the ability of daily life and quality of life of patients.

The research progress of rapid eye movement sleep behavior disorder in Parkinson's disease / 中华行为医学与脑科学杂志

Present data achieving from collecting showed it should be pay attention to the intimate connection between rapid eye movement sleep behavior disorder( RBD) and neurodegenerative diseases such as Parkinson’ s disease( PD) ,there is a scholar who has announced that RBD is the mark of alpha-synucle-in,and the PD patients who also have the RBD may appear some certain clinical features.To integrate exist-ing data and analyze the research progress of Parkinson's disease with REM sleep behavior disorder,it’ s ex-tremely close between PD and RBD,however,their exact mechanism and the accurate relationship remains to be further defined so that we can correspond treatment such as nerve protection as soon as possible,to help delay occurrence or progress about disease.

Popliteal artery endovascular angioplasty for the treatment of diabetic foot (a report of 65 cases) / 中国综合临床

Objective To evaluate the effect of pepliteal artery endovascular angioplasty for the treatment of diabetic foot. Methods 65 cases (69 limbs) of diabetic foot were treated by long bloon endovascular angioplasty. Results No death occured. 60 cases (64 limbs) were successfully treated and 5 cases (5 limbs) failed. The imme-diately success rate was 92.75%. The pain relieved, the temperature was improved and the ankle brachial index (ABI) was up to 0.84±0.11. Anterior tibial artery or posterior tibial artery of 39 limbs could be touched. 21 limbs were cured by debride and change dressings. 10 limbs were cured after the gangrene was ablated. 6 limbs were cured after the gangrene was debrided. 22 limbs were cured after toe amputation. Half of the foot was amputated. No limb was amputated. Every month was further consulted by Doppler and the rate of follow upwas 100%. 6 limbs of 6 cases were reobliterated (1,1,2,2 cases occurred after 1,6,12,18 month respectively.) and treated by endovascular an-gioplasty again. Conclusion Endovascular angioplasty below the knees for the treatment of diabetic foot is an effec-tive method for the limbs saving, with minimal invasive, safety, less complication and retreatment. It can be used as a first choice for the artery obliteration of diabetic foots.

Effect of modified Wendan decoction on expression of p-JNK and p-c-jun in cellular model of AD / 中华中医药杂志

Objective: To investigate the effect of Modified Wendan Decoction(MWD) on expression of p-JNK and p-c-Jun in cellular model of AD.Methods: NG108-15 cells were exposured to 5?mol/L A?25-35 for 24h to establish the cell model.After treating with contained-MWD serum,cells morphous were observed,survival rate was tested by MTT and cell apoptosis by FCM,the expression of p-JNK and p-c-Jun was measured by method of immuocytochemistry.Results: MWD obviously reduced the expression of p-JNK and p-c-Jun and cell's apoptotic rate.Compared with the model group,the expression of p-JNK and p-c-jun in the SP600125 group and the group treated with contained-MWD serum decreased significantly(P

Techniques of performances improvement of LED light source for instruments / 医疗卫生装备

This paper introduces the principle and characteristics of the LED constant-current and constant-power drive circuit for instrument's excitation light source.It also analyzes the steady-state and dynamic performances of the drive circuits.At last,it discusses the improving measures of the precision and stability for the drive circuit of LED excitation light source.

EFFECT OF UNDARIA PINNATIFIDA DIETARY FIBER ON VASCULAR ENDOTHELIUM IN HYPERLIPIDEMIC RATS / 营养学报

Objective To test the effect of Undaria pinnatifida soluble dietary fiber on endothelial function in hyperlipidemic rats. Method Forty rats were divided into 4 groups(n=10) :control group,hyperlipidemic model group,low dose dietary fiber-treated group(5%) ,high dose dietary fiber-treated group(10%) . After treatment for 8 w. Endothelium-dependent vasorelaxation in isolated aortic rings,the content of plasma malondialdohyde(MDA) ,nitric oxide(NO) and endothelin-1(ET-1) were determined. The protein expression of endothelial NO synthase(eNOS) was measured by Western blotting. Results Undaria pinnatifida soluble dietary fiber treatment significantly decreased MDA and ET-1 level. It also significantly improved endothelial function and plasma NO level concomitantly with unregulation of the expression of eNOS protein. Conclusion In hyperlipidemic rats Undaria pinnatifida soluble dietary fiber could improve vascular endotheliual function,which might be explained by its action to decreasing plasma ET-1 level and increased NO production.
