Objective: To study the anti-senile and anti-oxidative activities of Forsythia suspense leaves tea(FSLT) in mice. Methods: 36 ICR mice(7 mo age) were randomly divided into three groups: senior control group,ig distilled water ; FSLT1 group,ig FSLT 0.3 g ?kg-1?d-1 ; and FSLT2 group,ig FSLT 0.9 g?kg-1?d-1 .The other 12 ICR mice(young control group) were given ig distilled water. MDA and MAO-B in brain and mitochondria were measured. SOD,MDA and POD in heart, liver index, thymus index and spleen index were determined. Results: Forsythia suspense leaves tea may reduce the level of MDA and MAO-B, and increase the activities of SOD and POD. Conclusion: Forsythia suspense leaves tea may have anti-senile and anti-oxidative activities.

Objective To investigate the relationship between dystrobrevin binding protein 1 (DTNBP1) gene polymorphisms and cognitive function in patients with recurrent depressive disorder.Methods 49 recurrent depressive disorder patients and 60 age-,gender-and education-matched normal controls were recruited in this case-control study.Clinical symptoms were evaluated by HAMD and Wechsler adult memory scale,Wisconsin card sorting test,trail making test(TMT),verbal fluency test (VFT),S troop colorword test were used to evaluate cognitive function.The gene polymorphisms of DTNBP1 were determined by PCR-RFLP technique.SPSS 16.0 was used for statistical analysis.Results The distributions of genotypes in the patients and controls were consistent with Hardy-Weinberg equilibrium(P＞0.05).The time in trail making A task (73.4±30.5 vs 56.2± 11.7),the digital Span (9.6±2.3 vs 8.1±3.0),visual reproduction (9.6±2.3 vs 7.4±3.1),paired association learning (9.7±2.2 vs 6.1±4.2) and Spilling forward (9.1 ±2.4 vs 7.2±2.9) in Wechsler adult memory scale,the categories completed (1.8 ± 1.6 vs 2.5 ± 1.8),total trials (47.6± 1.1 vs 47.3± 0.7) and error numbers (28.5±5.3 vs 24.1±9.3) in WCST performs,and the word meaning interference score (18.4±9.0 vs 25.3±9.5) in Stroop color-word test were monitored.Patients with the genotype of rs9476867 G/G got higher interference number than patients with DTNBP1 rs9476867 C/G and C/C,and patients with the genotype of rs16876738 A/G spent more time to finish TMT-A than patients with rs16876738 G/G and A/A.G/G single nucleotide polymorphism (SNP) of rs9476867 and A/G SNP of rs16876738 affected attention ability.Conclusion DTNBP 1 gene polymorphisms are correlated with cognitive function in recurrent depressive disorder patients.

Objective:To study the effects of nourishing yin and supplementing kidney of Peikun Capsule. Methods: The Kindney yin vacuity model was made with thyroid hormone. Results: It was found that Peikun Capsules could reduce the oxygen consumption, raise the pain threshold, lower the body temperature and increase water intake of mice with kidney yin vacuity. Conclusion: Peikun Capsule has obvious effects of nourishing yin and supplementing kidney.

Nutrient agar medium was exposed in 0.085-0.092 T static magnetic fields for 12 h. Then we densities the optical densities at lamda = 600 (OD600) of Escherichia coli, Staphylococcus aureus and Bacillus subtilis in different culturing stage. The results were compared with those of control group in the normal geomagnetic field. The OD600 values of experimental groups of these three kinds of aerobes were significantly higher than those of control groups from 3h to 9h. However, after 11 h, there was no remarkable difference regarding the OD600 values between the two groups. The dissolved oxygen content of nutrient agar medium was determined by microtitration. The dissolved oxygen of nutrient agar medium under static magnetic for 12h increased 15% in average and there was significant difference when compared with the control. The results showed that the ferro-magnetic fields increased the dissolved oxygen content of nutrient agar medium significantly. These findings suggest that the effects of static magnetic fields on Escherichia coli, Staphylococcus aureus and Bacillus subtilis are related to the dissolved oxygen.

Objective: To conduct a preliminary evaluation for the usability of Carelink remote monitoring system by clinical physician. Methods: A total of 215 patients received cardiovascular implantable electronic devices (CIED) with Carelink remote monitoring function from 12 hospitals in China between 2012-01 and 2013-10 were prospectively enrolled. The patient's mean age was (62.3±14.3) years including 108 male and 107 female. There were 54 physicians completed questionnaire survey. Based on the type of CIED, the patients were divided into3 groups: PM (pace maker) group,n=110, ICD (implantable cardioverter defibrillator) group,n=54 and CRT (cardiac resynchronization therapy) group,n=51. The patients received routine hospital visit at 3 months of CIED implantation and meanwhile, they performed device data transmission at 3 and 6 months of Carelink remote monitoring. The time physician spent to evaluate data was collected at 3 months and the questionnaire survey was completed by physician at 6 months after CIED implantation. Results: All 54 physicians felt that Carelink remote monitoring system was simple to operate and easy to use. There were 147 patients ifnished hospital visit at 3 months after CIED implantation, the mean time for physician to evaluate data was (14.8±8.4) min; 150 patients ifnished Carelink remote monitor at 3 months after CIED implantation, the mean time for physician to evaluate data was (8.2 ±4.6) min,P<0.0001.Conclusion: Carelink remote monitoring system was easy to use, it may save time in follow-up study which with high satisfaction in clinical practice.

Objective To characterize hotline callers and related factors in Xiamen psychological aids hotline.Methods The data of 8397 callers who had used hotline were recruited from September 2010 to August 2015.During the calling,the callers were interviewed on their demographic characteristics,main counseling problems and suicidal related factors.Results Among the 8397 callers,1304 (15.5％) were frequent callers.Frequent callers had a high proportion of love and interpersonal problems,learning problems,mental illness problems.After adjusted for demographic characteristics,suicidal ideation or behavior (OR=1.417,95％CI:1.083～1.853),prior suicidal behavior 2 weeks before calling (OR=1.453,95％CI:1.058～1.996),symptoms of mental illness (OR=1.909,95％CI:1.188～3.065) were associated with repeated calls among hotline caller.Conclusion Counselor should pay attention to the suicidal related factors in psychological aids hotline to provide better service for hotline caller.

Objective To analyze the characteristics and correlated factors of attempted suicide among psychological aid hotline callers,and provide a reference for suicide prevention and intervention to the domestic psychological aid hotlines.Methods From September,2010 to August,2015,1 299 callers who had the database of attempted suicide among hotline callers were collected.During the calling,the callers were interviewed on their attempted suicides,depression and 10 correlated factors associated with caller's suicidal behaviors.Results Among 1 299 callers who received assessment of suicidal behavior relates factors,361 (27.8％) had evaluated of current suicidal ideation or behavior,223 (17.2％) had history of prior suicidal attempts.There was no significant difference in the incidence of suicide attempts among different gender,age and occupation.1 024 (78.8％) had symptoms of mental illness,794 (61.1％) had symptoms of anxiety,708 (54.5％) had symptoms of depression,864(66.5％) had concomitant two or more symptoms.Compared the caller's occurrence rate of suicidal attempter between single depression and concomitant other symptoms,the results found single depression and concomitant anxiety,concomitant obsession,concomitant panic and concomitant fear were statistically significant.Multiple logistic regression analysis showed that high depression emotion (β=O.389,OR=1.48,95％CI=1.08-2.02),the history of prior attempted suicide (3=0.487,OR=1.63,95％CI=1.19-2.22) and high hopelessness (β=0.618,OR=1.86,95％CI=1.32-2.60) were associated with the caller of ever attempted suicide behaviors.Conclusion Among the callers with attempted suicide,in order to improve the effectiveness of hotline prevention and invention,the psychological consultant should focus on the evaluation of concomitant mental symptoms,high depression emotion,history of prior attempted suicide and hopelessness.
