Further experiment showed that the ability of the cell to reduce nitroblue tetrazolium (NBT) dye, phagocytosis, as complement receptors and activities of acid phosphatase and ?-glucuronidase were all enhanced after differentiation. There were significant differences between the treated groupand the control group in NBT positive rate (62% v. s. 10%, P

Objective To explore the mechanism ofTiaozhong Huatan Anshen Mixture (THAM). Methods A total of 200 healthy Kunming mice were randomly and equally divided into first, second, third and fourth major groups. Each major group was further equally divided into blank group, control group and high, medium, low dose THAM groups. Each group was given an equal volume of NS, estazolam, or high, medium, or low dose THAM by gavage for 7 d. For the first major group, the changes in number of spontaneous activities after administration were evaluated. For the second major group, 60 min after administration, each group was given pentobarbital sodium (30 mg/kg body weight, minimum dose for all mice sleeping) by intraperitoneal injection, and the sleep time was recorded. For the third major group, 60 min after administration, each group was given pentobarbital sodium (15 mg/kg body weight, maximum dose for 90%-100% of all mice having righting reflex) by intraperitoneal injection. The number of mice falling asleep was recorded, and the sleep rate was calculated. For the fourth major group, mice were sacrificed after continuous administration 15 d. They were quickly removed brain tissue;homogenates were taken out in batches;5-HT and 5-HIAA levels in brain tissues were determined according to fluorescence spectrophotometric.Results Compared with the blank group, all treated groups had a reduced number of spontaneous activities, a shortened sleep latency, a prolonged sleep time, and an increased sleep rate after administration (P<0.01,P<0.05), with the most significant changes seen in the control group and high-dose THAM group (P<0.05), with out statistical significance between the two groups (P>0.05). Compared with the blank group, brain 5-HT and 5-HIAA levels in all treated groups increased in mice (P<0.01,P<0.05), with the most significant changes seen in the high-dose THAM group (P<0.05).Conclusion THAM has a significant sedative-hypnotic effect. The mechanism may be related to increasing brain 5-HT synthesis and metabolism.

Objective To study the effects of miR-130b on the neuronal migration in the developing embryonic mice cortex.Methods Pregnancy E15.5 mice were selected and plasmid of miR-130b was injected into the lateral ventricle of the embryonic brain.Two days after eletroporation,murine embryos were collected and cut into frozon coronal slices,then surveyed the neuronal migration under the fluorescence microscope.Results The neuronal migration rates were higher in miR-130b overexpression embryonic cortex,of which 75.1％ eletroporated neurons migrated into MZ,compared with the 22.1％ in control group.On the contrary,only 7.9％ eletroporated neurons stayed in the VZ/ SVZ in the experimental group,compared with the 69.3％ in control group.Conclusions miR-130b accelerates the neuronal migration in the developing embryonic mice cortex,its regulational role is worth studying.

Objective To explore the difference between the results of the cross-disciplinary joint teaching method and the traditional teaching method in medical humanity courses.Method 128 students in one military medical university were selected to be randomly assigned to the study group and the control group,using the cross-disciplinary joint teaching mode (study group,n=64) and traditional teaching mode (control group,n=64) in medical humanity courses.For the joint teaching mode,we compiled the teaching materials of medical humanities,formed the teaching team and organized the academic communication after class by social media.After all courses were finished,the subject cognition and approval of whole students were evaluated by the unified arranged examination and questionnaire.Then the data was processed by SPSS 18.0.Results On the aspect of subject cognition,the total scores of the study group were higher than control group in health law [(76.2 ± 3.34) vs.(72.5 ± 4.76);t=3.32,P=0.000] and medical ethics [(75.3 ±2.93) vs.(68.3 ± 3.10);t=4.01,P=0.000].On the aspect of subject approval,the recognition of the students of the study group in these three subjects were more than those of the control group except the selfevaluation of medical psychology (P=0.000).Conclusion The application of cross-disciplinary joint teaching method on medical humanity courses contributes evidently to the promotion of the medical humanity quality of clinical medical students.To implement this model,however,multi-sided resources are needed for colleges to coor-dinate,for perfect results require more practical exploration.

Frailty is a pre-disabled stage and associated with increased vulnerability to adverse health outcomes. Frailty has high preva-lence in older population. There are 2 principal emerging models of frailty, which are the phenotype model and the frailty index model. Many studies have developed tools to detect frailty, including self-report scales, such as PRISMA-7, Groningen Frailty Indicator (GFI), Ed-monton Frail Scale (EFS) and Simple Frailty Questionnaire (FRAIL);and single assessments, such as gait speed, timed up-and-go test, grip strength, pulmonary function test. Intervention of exercise and/or nutrition are benefical for frail older adults.

Objective To explore the effect of brief group psychological counseling in promoting students psychological health of high grade in primary school. Methods Two classes were randomly selected from a primary school in a community of Pudong New Area in Shanghai from October 2014 to November 2014, with stratified cluster sampling method in 4,5 grade ( the boy 30, the girl 24) as the research object, the other 2 classes (4,5 grade 1 classes;the boy 25,the girl 31) of students as control group, in the intervention group students brief group counseling was carried out, while the control group received the routine psychological health education course. Using the mental health diagnosis test (MHT) as a psychological assessment tool, MHT scores of two groups of students and factors were analyszed by the test analysis. Results Before intervention, the intervention group and the control group in the mental health diagnosis test (MHT) had no significant difference in each factor (P>0.05). After the intervention, significant were found differences between the intervention group and the control group in MHT learning anxiety, anxiety to people, self accusation tendency, allergic tendency, body symptom, terror tendency and the total score(6.46±3.01, 8.59±3.40; 3.04±1.91, 4.45±2.43; 3.56± 2.13, 5.30 ± 2.10; 4.37 ± 1.93, 5.84 ± 2.63; 3.76 ± 2.82, 5.46 ± 3.38; 2.15 ± 2.34, 3.91 ± 3.00; 32.44 ± 13.07, 44.52±17.59)(t=-3.47、-3.38、-4.30、-3.35、-2.87、-3.40、-4.10 ,P<0.05), and the average scores in the intervention group of each factor were lower than those of control group. Conclusion Brief group psychological counseling for higher-grade students of elementary school learning anxiety group, had better interventional effect on anxiety, self-blame tendency, the overall tendency of anxiety and other fields. It will have a positive impact on the allergic tendency, body symptom, terror tendency and other fields; it needs further evaluation in large sample for long-term effect.
