Objective To know the influence of psychological nursing on depression of patients with hypokalemic periodic paralysis.Methods Evaluated the mental condition by SDS for 46 patients with hypokalemic periodic paralysis and 30 health control, and then carried out certain psychological nursing measures for patients.Divided 46 patients with hypokalemic periodic paralysis into the intervention group and the control group randomly.There were 23 cases in each group.Psychological nursing cares and routine cares was used in the two group respectively, and then compared the incidence rate of depression in the two groups.Results The negative emotion in the patients with hypokalemie periodic paralysis was significant more obvious than that of in the health control.After the psychological nursing intervention, the SDS scores in the intervention group was released significantly than themselves before the intervention and the scores in the control group in the same time.Conclusions Depression was a common phenomenon in patients with hypokalemic periodic paralysis, characteristic psychological nursing intervention can effective release this kind of negative emotion, and then improve their rehabilitation.

Objective To observe the effects of stationary cycle training on lower limb muscle tension and motor function in children with spastic cerebral palsy.Methods Sixty-seven children with spastic cerebral palsy were divided into a treatment group (n =34) and a control group (n =33).Both were treated with routine rehabilitation therapy,including neurodevelopment treatment,massage and physical agent therapy.The treatment group additionally cycled on a stationary bicycle for 20 min a day,five days a week for 3 months.Muscle tension in the children's adductor,hamstring and gastrocnemius muscles was evaluated using the modified Ashworth scale (MAS),while the adductor angle,popliteal fossa angle and foot dorsiflexion angle were measured using a joint protractor.Moreover,the 88-item version of the Gross Motor Function Measure (GMFM-88) was used to evaluate gross motor function.Results After treatment the average muscle tension of both groups was significantly lower than before treatment.The average muscle tension scores of the adductors,hamstrings and calf muscles of the treatment group [(1.79±0.54),(1.00±0.60),(2.29 ±1.77)] were significantly lower than those of the controls [(1.82 ± 0.53),(1.15 ± 0.44),(2.52 ± 1.89)].The adductor angles,popliteal fossa angles and foot dorsiflexion angles of both groups were significantly larger than before treatment,and the angles in the treatment group [(97.06 ± 19.03) °,(53.38 ± 12.54) ° and (8.38 ± 9.11) ° respectively] were significantly larger on average than those in the control [(98.94 ± 21.42) °,(56.52 ± 12.90) ° and (5.30 ± 14.30) ° respectively].After treatment the total GMFM scores of both groups were better than before treatment,but the treatment group's average score(138.18 ± 54.86) was significantly better than that of the control group(112.21 ± 62.44).Conclusion Three months of stationary cycle training can effectively reduce the muscle tension of children with spastic cerebral palsy and improve their motor function.

Objective To investigate the correlation between orexin A and the serine proteinase inhibitor vaspin in obese rats with insulin resis?tance(IR)induced by high?fat diet and elaborate the possible action mechanism of orexin involvement in fat metabolism in IR pathological process. Methods A total of 75 4?week?old male Sprague?Dawley rats were randomly divided into the normal dietary group(NC group,n=20)and the high?fat dietary group(HF group,n=55)to establish the model of obese rats with IR,the euglycemic insulin clamp technique was used to determine re?lated indicators of insulin resistance and lipid metabolism. The rats were treated with orexin A(1×10-8?1×10-6 mol/L)by hypodermic injection. The serum levels of orexin A and vaspin in rats were detected with enzyme linked immunosorbent assay. Results After 6 weeks of high?fat diet,the se?rum glucose,insulin,TC,TG and LDL?C were increased significantly in HF group than in NC group,while GIR60~120 in obese rats was decreased significantly[(16.31 ± 1.54)vs(30.22 ± 2.76)mg/(kg · min),P<0.05]. The serum vaspin level was increased 177.08%in HF group compared with NC group(P<0.05). With hypodermic injection of orexin A(1×10-8 mol/L,1×10-7 mol/L and 1×10-6 mol/L),the levels of serum vaspin in?creased 25.00%,68.75%,and 120.83%in NC group and increased 7.52%,24.06%,and 40.60%in HF group. There was a positive correlation be?tween vaspin and orexin A,glucose,insulin,TC,TG,and LDL?C(r1=0.482,P1=0.02,r2=0.515,P2=0.02,r3=0.303,P3=0.04,r4=0.388,P4=0.03,r5=0.255,P5=0.04,r6=0.253,P6=0.04)and a negative correlation between vaspin and HDL?C(r=-0.226,P=0.04)in obese rats with IR. Conclusion High?fat diet can induce insulin resistance and obesity in rats,and orexin A is closely correlated to vaspin in obese rats with insu?lin resistance. Orexin A increases serum vaspin expression and thus involves in onset of insulin resistance in obese rats.

Crohn’s disease( CD)is a gastrointestinal progressive granulomatous disease with unknown etiology. It is characterized as active stage alternating with remission stage,long-term course with many complications,sometimes needing surgery and having the tendency of relapse in patient ’s whole life. Therefore,it is important to define an effective therapeutic endpoint to ameliorate the natural course of CD. This article reviewed the progress in defining treatment endpoint of CD.
