ABSTRACT
In order to improve the wearing comfort and bearing effectiveness of the exoskeleton, based on the prototype and working mechanism analysis of a relaxation wearable system for knee exoskeleton robot, the static optimization synthesis and its method are studied. Firstly, based on the construction of the virtual prototype model of the system, a comprehensive wearable comfort evaluation index considering the factors such as stress, deformation and the proportion of stress nodes was constructed. Secondly, based on the static simulation and evaluation index of system virtual prototype, multi-objective genetic optimization and local optimization synthesis of armor layer topology were carried out. Finally, the model reconstruction simulation data confirmed that the system had good wearing comfort. Our study provides a theoretical basis for the bearing performance and prototype construction of the subsequent wearable system.

Objective To investigate the effect of psychological intervention combined with venlafaxine and risperidone in the treatment of refractory depression and its influence on the quality of life .Methods 97 patients with refractory depression were selected .According to the random number table , they were divided into the observation group(50 cases) and the control group(47 cases).The control group was given venlafaxine combined with risperidone treatment,the observation group received psychological intervention on basis of the control group .The Hamilton depression scale ( HAMD) of patients in the two groups before treatment ,4,8 and 12 weeks after treatment were recorded .The curative effect after 12 weeks of treatment was evaluated ,the adverse reaction was evaluated by the side effects scale ( TESS ) , and the quality of life ( WHOQOL-100 ) of the two groups before treatment , 12 weeks after treatment were compared .Results The HAMD score of the two groups had no statistically significant difference before treatment(t=0.307,P>0.05).After treatment for 4,8,12 weeks,the HAMD scores of the two groups were significantly lower than before treatment (t=5.743,17.756,27.288,4.595,15.801,23.247,all P<0.05),and the HAMD scores in the observation group after treatment for 8 weeks and 12 weeks were significantly lower than those in the control group(t=0.887,3.717,5.854,all P<0.05).After 12 weeks of treatment,the total effective rate of the observation group was significantly higher than that of the control group (90.00％ vs.74.47％,χ2 =4.043,P <0.05 ).There was no statistically significant difference in incidence rate of adverse reactions between the two groups (26.00％vs.25.52％,χ2 =0.003,P >0.05).The WHOQOL-100 scores of the two groups had no statistically significant differences before treatment(t=0.597,0.497,0.378,0.923,0.136,all P>0.05).The WHOQOL-100 scores of the two groups after treatment were significantly higher than those before treatment ( t =11.668,8.701, 6.857,7.053,2.247,4.815,4.639,2.999,4.117,2.011,all P<0.05).After treatment,the psychological and physiological independence and social relationship domain scores in the observation group were significantly higher than those in the control group(t=5.618,3.295,4.335,3.603,all P<0.05).Conclusion Psychological interven-tion combined with venlafaxine and risperidone in the treatment of refractory depression can significantly improve the clinical efficacy ,improve the clinical symptoms and the quality of life of patients .
ABSTRACT
Objective To study effects of shuganjieyu capsule of plasma glucose and lipid metabolism and sleep and body weight in patients with depression.Methods 90 patients of depression who received therapy from July 2013 to July 2016 in our hospital were selected.According to random number table, those patients were divided into the observation group ( n =45 ) and the control group ( n =45 ) .The control group was treated with citalopram, while the observation group was treated with shuganjieyu capsule, then glucose and lipid metabolism, sleep, weight and clinical curative effect were compared.Results After treatment, the fasting blood glucose (FBG), postprandial 2h blood glucose (2 hPG), triacylglycerol (TG), total cholesterol (TC) in the observation group were lower than the control group(all P<0.05), the sleep state self rating scale (SRSS) and the Pittsburgh sleep quality index ( PSQI) in the observation group were lower than the control group ( all P <0.05 ) .The body weight and body mass index in the observation group were lower than the control group (all P<0.05).The total effective rate in the observation group 95.56% (43/45)was higher than the control group 77.78% (35/45) (P<0.05); the incidence of adverse reactions in observation group 20.00% (9/45) was lower the control group 46.67% (21/45) ( P <0.05).Conclusion Shuganjieyu capsule is well for depression, which can conducive to maintaining glucose and lipid metabolism, weight stability, and improve sleep quality and clinical symptoms, and high security,it's worthy of application and promotion.
ABSTRACT
Objective To explore the curative effect of quetiapine combined with paroxetine in the treatment of bipolar depression,and to provide reference for the choice of clinical treatment.Methods According to the digital table,96 patients with bipolar disorder were randomly divided into observation group and control group,48 cases in each group.The control group was treated with quetiapine orally,the observation group was treated with quetiapine combined with paroxetine.After 6 weeks of treatment,the clinical curative effect,the Montgomery Asberg Depression Rating Scale and the Beck pull fan Sen Mania Rating table score before and after treatment were compared between the two groups.At the same time,the adverse reactions of the two groups were compared.Results After 6 weeks of treatment,the total effective rate of the observation group was 70.83％,which was significantly higher than 50.00％ in the control group,the difference was statistically significant(x2 =4.356,P =0.037).After 6 weeks of treatment,the Montgomery Asberg Depression Rating quantity score in the observation group was (14.01 ± 2.95) points,which was significantly lower than (18.07 ± 3.05)points in the control group,the difference was statistically significant (t =5.527,P =0.036).The Baker-pull fan Sen Mania Rating score before and after treatment between the two groups had no statistically significant differences.There were no serious adverse reactions in the two groups.Conclusion Quetiapine combined with paroxetine can effectively inhibit bipolar depressive episodes,avoid manic episodes,has good clinical efficacy and high safety,it is worthy of popularization and application.
ABSTRACT
Objective To observe plasma albumin,total bilirubin and serum inflammatory factors,gonadal hormone levels in men with bipolar disorder,and to provide evidence for the diagnosis of the disease.Methods 48 men with bipolar disorder were selected as disease group,and 42 cases of male physical examination were selected as control group.Plasma albumin,total bilirubin and serum inflammatory factors,gonadal hormone levels of the two groups were detected.Results The levels of serum albumin and total bilirubin of the disease group were (43.4 ± 3.9)g/L and (9.4 ±1.9)μmol/L,which were lower than those of the control group[(49.6 ±3.0)g/L and (11.8 ± 2.1)μmol/L],the differences were statistically significant (t =8.361,5.692,all P 0.05).The serum level of E2 of the disease group was (23.2 ± 16.1)pg/mL,which was lower than (35.9 ±18.0)pg/mL of the control group,the serum T level of the disease group was (10.8 ±4.9)ng/mL,which was higher than (4.2 ±1.6)ng/mL of the control group,the differences were statistically significant(t =3.533,8.344,all P <0.05).Conclusion Plasma albumin,total bilirubin and serum IL -1β,IL -4 levels can be used as references for clinical diagnosis of bipolar disorder,and serum E2 and T levels can be used as risk factors for bipolar disorder.
