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.

Objective:To investigate the prognostic value of estrogen receptor (ER), progesterone receptor (PR), and Ki-67 in breast can-cer patients receiving neoadjuvant chemotherapy (NAC) and explore the association of chemotherapy regimens and cycles with the outcome of NAC. Methods:Clinical data of cancer patients receiving NAC were retrospectively analyzed. All the patients were admit-ted in Tianjin Medical University Cancer Institute and Hospital from January 2015 to December 2015. All statistical analyses were per-formed using SPSS version 19.0. The relationship among the outcome of NAC, molecular subtype, expression levels of ER, PR, and Ki-67, and chemotherapy regimens and cycles was investigated. Results:Only five HER-2(+) patients accepted the addition of trastuzum-ab in treatment, and few cases were excluded from the statistical analysis based on the effect of chemotherapy regimens. The effec-tiveness of NAC was positively correlated with the expression of Ki-67 whereas negatively correlated with the expression levels of ER and PR (P<0.05). In patients receiving NAC, the patients with Luminal subtype had worse outcome than those with non-Luminal sub-type (P=0.033). The invalid efficacy of pathologic evaluations of Luminal and non-Luminal NAC were 10.1%and 1.3%, respectively. No significant difference was found in the outcome among patients receiving TE, TEC, or EC-T;however, patients who received more than four cycles of NAC had better outcome than others (P=0.016). The outcome was statistically significant when the cut-off value of Ki-67 was 25%. Conclusion:Ki-67 proliferative index could be used as a prognostic marker to NAC in breast cancer patients. The cut-off value of Ki-67 should be determined on the basis of the data of each cancer patient. The curative effect of NAC was poor, and Luminal pa-tients with chemotherapy were insensitive and could be considered for surgical treatment. Patients who received less than four cycles of NAC had worse outcome than others, and prompt NAC foot treatment could improve the efficiency.

Objective:To study the effect of Ginkgo biloba extract (EGb761) on metabolism of aflatoxin B_1(AFB_1) in Wistar rats. Methods:Seventy one Wistar rats were divided into three groups at random: group A (AFB_1 group), group B (AFB_1+EGb761 group), and group C (control group). The rats in groups A and B were given AFB_1(intraperitoneal injection, 100-200 μg/ kg body weight, 1-3 times/week). The rats in group B were fed the food containing EGb761 while the rats in groups A and C were given normal food. Blood samples were collected and liver biopsy was performed on the 14th, 28th and 42nd week. All the rats were sacrificed at the 64th week. The incidence of hepatoma was observed. The hepatic phase Ⅰ drug-metabolizing enzyme CYP450 and phase Ⅱ enzyme GST were detected by spectrometry. The serum AFB_1-lysine adduct was determined by high performance liquid chromatography (HPLC). The expression of 8-hydroxydeoxyguanosine(8-OHdG) was measured by immunohistochemistry. Results:The incidence of hepatocellular carcinoma (HCC) in group B was significantly lower than that in group A (26.92% vs 76.00%,P<0.001). No hepatocellular carcinoma developed in group C. EGb761 had no effects on the activities of CYP450 and GST in rat liver tissues. The level of AFB_1-lysine adduct reached the peak (4 356.01 pg/mg albumin) at the 14th week in group A. EGb761 significantly inhibited the formation of AFB_1-lysine adducts in serum by 13.07% at the 14th week (P=0.033), and 73.63% at the 42nd week (P=0.002). The expression of 8-OHdG protein in rat liver tissues in group B was significantly lower than that in group A at the 28th, 42nd, and 64th week (P<0.05). Conclusion:The main mechanism underlying the effect of EGb761 in blocking hepatogenesis induced by AFB_1 may not be fully related with its influence on the activity of liver phase Ⅰ and phase Ⅱ metabolizing enzymes. EGb761 inhibites the production of AFB_1-lysine addcuts, decreases the expression of 8-OHdG protein, and finally alleviates the DNA oxidative injury, which may be one of the mechanisms for the effects of EGb761 in inhibiting or delaying hepatogenesis induced by AFB_1.

BACKGROUND:Dendritic cel s can regulate the immunological reaction in the intestinal tract, this functional deficit may induce inflammatory bowel disease. Tol-like receptor-4/nuclear factor-κB pathway is highly involved in this reaction. OBJECTIVE:To establish experimental colitis model in rats, to observe effects of resina draconis on dendritic cel s and Tol-like receptor-4/nuclear factor-κB expression in rats with experimental colitis, and to explore its action mechanism. METHODS:A total of 44 male Sprague-Dawley rats were randomly assigned to four groups (n=11):blank control group, model group, resina draconis group, 5-aminosalicylic acid treatment group. With the exception of blank control group, 2,4,6-trinitrobenzenesulfonic acid-induced ulcerative colitis models were established in the model group, resina draconis group and 5-aminosalicylic acid treatment group. After the models were successful y established, the rats in the resina draconis and 5-aminosalicylic acid treatment groups were intragastrical y treated with resina draconis [(0.75 g(kg·d)] and 5-aminosalicylic acid [100 mg(kg·d)] respectively for 10 days. RESULTS AND CONCLUSION:Disease activity index, macroscopic colonic damage score and histopathological score were significantly decreased in the resina draconis group compared with the model group (P<0.05). Symptoms and tissue damages were obviously lessened in the 5-aminosalicylic acid treatment and resina draconis groups compared with the model group. Expression rates of CD80 and CD86, as wel as expression levels of Tol-like receptor-4 and nuclear factor-κB were significantly higher in the model group compared with the blank control group, resina draconis group and 5-aminosalicylic acid treatment group (P<0.05, P<0.01). Tol-like receptor-4 and nuclear factor-κB expression was significantly lower in the resina draconis group than that in the 5-aminosalicylic acid treatment group. Experimental findings indicate that, resina draconis can partial y relieve experimental colitis symptoms in rats and effectively inhibit the activation of dendritic cel s in the mesenteric lymph node. Resina draconis can relieve enteric inflammatory reaction by suppressing the expression of Tol-like receptor-4 and nuclear factor-κB in rats.
