Journal of Zhejiang Chinese Medical University 2015;(2):95-97
Objective] To study emotional counterbalance therapy which is used in depression treatment ,it plays an important role in the treatment of emotional disorders. [Method] With the research methods of taking depression for example ,through the sad,fear of these two emotional factors to explore the pathogenesis of depression,and analyze“happiness restrains sadness“ and“thought restrains fear”in the emotional counterbalance therapy, which are used in the depression clinical application.[Result]Emotional counterbalance uses one or more of the emotions to regulate ,control,overcome the other one or more negative emotions,which based on the restriction among the five elements theory is a kind of psychological therapy.Sadandfearare the most common chief complaints in depression which belong to the emotional depression in depression disease of Chinese medicine. On the basis of “sad doing harm to the lungs”and “dread doing harm to the kidneys”,lung,kidney and depression etiology,pathogenesis,symptoms are closely related. This reflects the lung,kidney play an indispensable role in the treatment of depression. It has significant curative effects to apply the theory of emotion counterbalance,such as happiness restrains sadness,thought restrains fear to cure diseases. At the same time,with a relaxed and pleasant mood,actively guiding to help thinking is also the treatment of depression,pessimistic disappointment medicine.[Conclusion] According to the restriction among five elements theory,to use the relation and restriction between emotion and five zang-organs to regulate emotional disorders can restore to the normal balance,which is an effective psychological treatment for emotional disorders.The therapy should be used alone or combined with traditional Chinese medicine treatment in different situations to relive the treatment effect.

Chinese Journal of Obstetrics and Gynecology 2012;47(6):412-417
Objective To investigate the relationships between concentrations of free fatty acid (FFA) in maternal serum and oxidative damage levels in placental mitochondria and preeclampsia ( PE)-Methods A total of 60 women with PE and 60 normal pregnant women as control participated in this study.All were admitted to Fujian Maternity and Child Health Hospital for delivery from August 2010 to May 2011.Patients with PE were divided into early-onset group ( n =30,presented at < 34 weeks of gestation ) and late-onset group ( n =30,presented at ≥ 34 weeks of gestation),with 30 normal pregnant women as early control group ( < 34 weeks of gestation ) and 30 as late control group ( ≥34 weeks of gestation).Improved copper agent colorimetry was used to detect FFA in maternal serum Ultraviolet colorimetry was used to detect glutathione peroxidase (GPX) and catalase (CAT) activity in maternal placenta and malondialdebyde (MDA) and permeability transiton (PT) pore in placental mitochondria.Total superoxide dismutase (SOD) assay kit-WST was used to detect SOD activity in placenta.Real-time fluorescent quantitative PCR was used to detect mitochondrial DNA (mtDNA) expression in placenta.Results ( 1 ) Maternal serum FFA was ( 1.6 ±0.5 ) mmol/L in early-onset PE group and ( 1.5 ± 0.4) mmol/L in lateonset PE group,significantly elevated as compared to ( 1.0 ± 0.5 ) mmol/L in early control group and (0.9 ±0.5) mmol/L in late control group (P < 0.05 ). However,no significant difference was found between early-onset and late-onset PE groups (P > 0.05 ).(2) The mean placental GPX,CAT and SOD activity were significantly decreased in the early-onset PE group [ (47 ±6),( 19 ±5),(62 ± 13) U/mg]and late-onset PE group [ (67 ±6),(20 ±4),(96 ± 17) U/mg] as compared to late control group [ (80 ±3),(55 ± 3 ),( 123 ± 19 ) U/mg],respectively ( P < 0.05 ).(3) The mean placental mitochondria MDA was significantly elevated in the early-onset PE group [ (115 ± 22) nmol/mg] and late-onset PE group [(90±17) nmol/mg] as compared to late control group [(52 ± 11) nmol/mg,P <0.05].The mean absorption value that present the permeability of placental mitochondria PT pore was significantly elevated in the early-onset PE group (0.086 ±0.013) and late-onset PE group (0.069 ±0.014) as compared to late control group (0.052 ± 0.0 12,P < 0.05 ).The mean placental mtDNA expression was significantly elevated in the early-onset PE group (3.0 ±0.7) and late-onset PE group (2.8 ±0.7) as compared to late control group ( 2.6 ± 0.6,P < 0.05 ).( 4 ) The mean placental mitochondria MDA concentration correlated positively with the concentrations of FFA in maternal serum in the early-onset PE group ( r =0.703,P <0.05 ) and late-onset PE group (r =0.457,P < 0.05 ),and negatively with placental antioxidant enzyme in the early-onset PE group ( r =- 0.652,- 0.787,- 0.952 ; P < 0.05 ) and late-onset PE group ( r =-0.378,-0.689,-0.854; P<0.05).Conclusions Increased FFA in maternal serum and high levels of oxidative damage in placental mitochondria may be involved in the pathogenesis of preeclampsia.Increased FFA in serum and decreased activity of antioxidant enzyme in placenta may contribute to oxidative damage levels in placental mitochondria in women with PE.
