Objective · To explore family medical intervention model of senile dementia with behavioral and psychological symptoms. Methods · Four streets of Changning District in Shanghai were randomly selected and subjects were enrolled according to the inclusion criteria, who were randomly divided into the intervention group (n=71) and control group (n=70). The intervention group received door-to-door service from psychiatric doctors, given drug treatment and psychological intervention. Subjects were evaluated by several scales, including Behavioral Pathology in Alzheimer's Disease Rating Scale (BEHAVE-AD), Mini-Mental State of Examination (MMSE), Activity of Daily Living Scale (ADL), Quality of Life-Alzheimer's Disease (QOL-AD), and Generic Quality of Life Inventory-74 (GQOLI-74), at baseline and by the end of 6 months and 12 months. Results · ① There was no significant difference in the total scores and all factor scores of BEHAVE-AD between the two groups before intervention (P>0.05). Repeated measures analysis of variance revealed a significant main effect of time (P<0.001). The between-group effect was significant in the total scores of BEHAVE-AD and the factor scores of affective disorder, anxiety and terror (P<0.001). The interactive effect of time×group was significant in the total scores of BEHAVE-AD and the factor scores of delusion and affective disorder (P<0.05). ② Intergroup comparison of the BEHAVE-AD scores indicated that by the end of 6 months, factor scores of hallucination, circadian rhythm disorder, affective disorder, anxiety and terror of the intervention group were remarkably better than those of the control group and the differences were statistically significant (P<0.01). By the end of 12 months, total scores of BEHAVE-AD, and factor scores of delusion, conduct disorder, affective disorder, anxiety and terror of the intervention group were remarkably better than those of the control group and the differences were statistically significant (P<0.01). ③ There was no significant difference in the scores of MMSE, ADL, QOL-AD and GQOLI-74 between the two groups before intervention (P>0.05). Repeated measures analysis of variance revealed a significant main effect of time (P<0.001). The between-group effect was significant in the scores of MMSE and QOL-AD (P<0.001). The interactive effect of time×group was significant in the scores of MMSE, ADL, QOL-AD, and GQOLI-74 (P<0.05). ④ Inter-group comparison of MMSE, ADL, QOL-AD, and GQOLI-74 scores indicated that by the end of 6 months, scores of MMSE of the intervention group were remarkably better than those of the control group and the differences were statistically significant (P<0.05). By the end of 12 months, scores of MMSE, ADL, QOL-AD, and GQOLI-74 of the intervention group were remarkably better than those of the control group and the differences were statistically significant (P<0.05). Conclusion · The family medical intervention model of door-to-door services from psychiatrists integrating multidisciplinary team is effective to attenuate the mental and behavioral symptoms of senile dementia patients, and can improve the quality of life of patients and caregivers. The effect of persistent implementation will be more remarkable.

The aim of the study is to evaluate the effects of the single and mixed decoction of Thallus laminariae (kelp) and Glycyrrhiza glabra (licorice) on the metabolism and their difference. The mixed decoction of kelp and licorice and the single decoction were made and intragastrically administered to the SD rats. The effect on system metabolism, the toxicity of liver and kidney were assessed by GC-MS profiling of the endogenous molecules in serum, routine biochemical assays and histographic inspection of tissues from SD rats, separately. The mixed decoction of kelp and licorice induced more obvious pathological abnormalities in SD rats than a single decoction of kelp, while the extracts of licorice did not show any pathological change. Neither the mixed, nor the single decoction showed abnormal histopathology. After intragastric administration of extracts for 5 days, the mixed decoction induced a decrease of ALT (no significant change in the groups of single decoction) and an increase of BUN (so did the single decoction of kelp). Metabolomic profile of the molecules in serum revealed that the metabolic patterns were all obviously affected for the three groups, i.e., the mixed and single decoction of kelp and licorice. The rats given with the single decoction of kelp showed a similar pattern to that of the mixed decoction, indicating that the kelp primarily contributed the perturbation of metabolism for the mixed decoction. All three groups induced a decrease of branched chain amino acids, TCA cycle intermediates and glycolysis intermediates (e.g., pyruvic acid and lactic acid) and an increase of 3-hydroxybutyric acid. Kelp decoction showed stronger potential in reducing TCA cycle intermediates and glycolysis intermediates than the other two groups, while the levels of branched chain amino acids were the lowest after licorice extracts were given. These results suggested that the effect of the mixed decoction on metabolism was closely associated with both kelp and licorice. The continuous administration of single decoction of kelp and the mixed decoction of licorice and kelp resulted in pathological abnormalities in kidney of SD rats. The mixed decoction of kelp and licorice distinctly perturbed sera molecules and hence system metabolism, which showed associated with those of kelp and licorice. Although the metabolic effect was associated with both kelp and licorice, the results suggested kelp contributed to it primarily.

Objective:To evaluate the immunogenicity of Madin-Darby canine kidney (MDCK) cell-based quadrivalent influenza split vaccine (MDCK-Va) combined with different adjuvants.Methods:Different doses of MDCK-Va and chicken embryo-based quadrivalent influenza split vaccine (egg-Va) were intramuscularly immunized BALB/c mice twice with an interval of three weeks. Serum samples were collected to detect antibody titers using hemagglutination inhibition (HI) assay. BALB/c mice were immunized with different doses of MDCK-Va combined with QS21, AddVax, PolyI∶C, CpG ODN 1826 and AddVax/PolyI∶C (Add/Poly), respectively. HI and microneutralization assays were used to detect antibody titers 21 d after the first and booster immunization. Spleen tissues were collected from the mice immunized with 10 μg MDCK-Va combined with the above adjuvants 5 d after the booster immunization to analyze spleen index and the types of spleen cells.Results:The immunoprotective effect of MDCK-Va was not inferior to that of egg-Va. MDCK-Va combined with each of the above adjuvants could induce higher HI antibody titer than MDCK-Va alone, especially the QS21/Va and Add/Poly/Va groups, and the differences were statistically significant. For H1N1 vaccine, the Pearson′s correlation coefficient ( r) between HI antibody and neutralizing antibody was 0.737-0.910, and for H3N2 subtype vaccine, the value of r was 0.839-0.947. Compared with the MDCK-Va group, the QS21/Va group showed significantly increased spleen index and decreased proportion of single lymphocytes. QS21 and Add/Poly were much better than other adjuvants in stimulating mouse splenic neutrophils and CD4/CD8 cells. Conclusions:Add/Poly had a stronger immune enhancement effect on MDCK-Va, suggesting that it was a potential adjuvant for MDCK-Va. The antibody titer detected by HI and MN assays had a strong positive correlation.
