Objective To systematic evaluate the effectiveness of different psychological treatment methods in the management of postpartum depression (PPD). Methods Relevant literature between 1968 and February 2009 was searched by computer and manual. And suitable randomized controlled trials were brought into this research according to the inclusion and the exclusion criteria. Then meta-analysis was used in four time periods including immediately post- treatment,6 months after treatment, 1 year after treatment and 5 years after treatment.Results A total of eight studies were brought into this research. Immediately post-treatment,it showed significant differences between intervention and control groups of CBT (P = 0.03 ), non-directive counseling(P = 0.0009), psychodynamic therapy (P = 0.005 ) and interpersonal psychotherapy (P = 0.002 ). Within 6 months after treatment, it showed significant differences between intervention and control groups of CBT(P = 0.006 )and peer support (P =0.03) ,but not in non-directive counseling. Within 1 year after treatment,it showed significant differences between intervention and control groups of CBT(P= 0.02 ), but not in non-directive counseling and psychodynamic therapy.Within 5 years after treatment, no significant differences in intervention and control groups of CBT, non-directive counseling and psychodynamic therapy. Conclusions A total of five psychological treatment methods are effective in the management of PPD. CBT has both good short-term and long-term effectiveness. Non-directive counseling and psychodynamic therapy only have a good short-term effectiveness, but a poor long-term effectiveness. Interpersonal psychotherapy and peer support have a good short-term effectiveness.

Spinal muscular atrophy in childhood is one of the most common neuromuscular disorders with an autosomal recessive mode of inheritance. The main pathogenesis is homozygous loss and small intragenic mutations of the SMN1. SMN2 ,as a very identical copy of SMN1, modulates the disease severity. The functional difference between both genes is a variance of single nucleotide within the coding region, causing silent mutation obviously to decrease SMN2 transcripts. Histone deacetylase inhibitors have been shown better perspective in clinical trials.

Age-related macular degeneration (AMD) is one of the leading causes to blindness worldwide in elderly population.Innate immune system elements, such as macrophages and cytokines, play an important role in AM D pathology and pathogenesis.In AMD,macrophages can be functionally polarized into M1 (classically activated) and M2 (alternatively activated), as well as regulatory cells, in response to systems biology approaches.Imbalances in the M1 and M2 populations together with activation of retinal microglia are observed and potentially contribute to tissue degeneration.In this review, the phenomenon of macrophage polarization in AMD study was summarized, and the relationship between macrophage polarization and dry AMD,wet AMD,AMD related risk factors were discussed.

With more details of end-of-life-care such as moral principle and standard management,the development condition of end-of-life-care in China is compendiously introduced, and "1,3,9——PSD"service mode of end-of-life-care is also put forward in this artical.

ObjectivesTo investigate the effect of thyroid hormone on the expression of deiodinase and myelin basic protein in brain tissue of neonatal rats with germinal matrix-intraventricular hemorrhage (GM-IVH), and its nerve protective effect.Methods Sixty premature rabbits of gestational age 29 days were randomly divided into control, model and intervention groups. The prema-ture rabbits in model and intervention groups were given intraperitoneal injection of 50% glycerol to establish GM-IVH animal model and the premature rabbits in control group were given the same dose of saline. The GM-IVH was screened by cranial ultrasound. The premature rabbits with GM-IVH in intervention group were given intraperitoneal injection of triiodothyronine and the other two groups were given the same dose of saline. At 3 days, 7 days and 14 days after birth, the premature rabbits were killed and the brain tissue were quickly separated. The expression of type 2 iodothyronine deiodinase (D2) and type 3 iodothyronine deiodinase (D3) of periventricular zone tissue were detected by western blot method. The expression of myelin basic protein (MBP) were detected by immunohistochem-ical method.ResultsThe expression of D2 in brain tissue increased gradually in three groups. At the same time point, the expression of D2 was the lowest in the model group, the highest in the control group, and the middle in the intervention group. The differences of D2 among three groups were statistically signiifcant (allP<0.001). The expression of D3 increased gradually in the control and model groups, while it was the highest in the intervention group at day 7. At the same time point, the expression of D3 in the control group was the lowest, it was higher in intervention group than that in the model group at 3 days, then it was higher in the model group than that in the intervention group. The differences of D3 among three groups were statistically signiifcant (allP<0.001). The expression of MBP increased gradually in the control and intervention groups, and it decreased gradually in the model group. At the same time point, the MBP was the lowest in the model group, it was the highest in the control group, and it was the middle in the intervention group. The differences of MBP among three groups were statistically signiifcant (P<0.001).ConclusionsThe expressions of D2 and MBP in the brain tissues of premature rabbit with the GM-IVH increased while the expression of D3 decreased in some extent after thyroxine intervention.

In order to investigate the possibility of analysis of single strand DNA by using DNA biosensor, we developed a quartz crystal DNA biosensor and studied its performances. The single strand DNA probe was immobilized on the surface of gold filled quartz crystal by biotin immunoreaction. The DNA biosensors were used to detect the complete complementary and single base mismatch complementary single strand DNA in solution. The DNA biosensors were regenerated with 0 1mol/L HCl after hybridization. The hybridization sensitivity of quartz crystal DNA biosensor is 10ng/ml. In the range of 5～40ng/ml, there was a linear correlation between responding signals and concentrations of complementary single strand DNA with a high specificity. The DNA biosensor could be repeatedly used over 5 times by using 0 1mol/L HCl for regeneration.
