The Outline-style homework is introduced, which is one of the characteristic diagnostic methods of TCM psychology. The outline-style homework contents include①the painful, sad or aggrieving things.②the person(s) or object(s) or event(s) that your are/were afraid of.③the past events about love relationship and sex that you are reluctant or feel too ashamed to mention.④the most trusted, dependence, unforgettable person, and why.⑤the most relaxed , happy time, and why? It comes from the ancient Chinese emotional theory and modern TCM psychotherapy practice. Nowadays, this method is widely used to help doctors quickly collect the patient's mental condition, growth experience, and convenient for clinical treatment.

Objective To explore the effect of behavioral training on the differentiation of neural stem cells in the dental gyrus (DG) in rats with hippocampus infarction. Methods Seventy-eight Sprague-Dawley rats were randomized into infarction plus behavior training group, infarction group and control group. Photochemistry method was used to induce hippocampal infarction in rats of the infarction plus behavioral training group and infarc-tion group. At 1 day after surgery, Morris water maze training was used for infarction plus behavioral training group, free-movement without training was performed for infarction group. Double staining immunofluorescence was used to detect the co-expression of bromodeoxyuridine (BrdU) with neuronal nuclei ( NeuN ) or glia fibrillary acidic protein (GFAP) in the DG at different time points. Results Few BrdU/NeuN and BrdU/GFAP double staining cells were observed in the DG of control rats. In the infarction group and infarction plus behavioral training group the number of BrdU/NeuN and BrdU/GFAP double-stained cells increased in the DG on the opposite side compared with the control group on 14th, 21st, 28th and 35th days after surgery (P < 0.05 ). There observed significantly more BrdU/NeuN and BrdU/GFAP double-stained cells in the infarction plus behavioral training group than that in the infarction group on the 14th, 21st, 28th and 35th days after surgery ( P < 0.05 ). Conclusion Behavioral training can accelerate the differentiation of neural stem cells to neuron and astrocyte, by which to promote the re-covery of neural functions.

Methods Totally, 60 adult rats were selected and divided into blank control group( n=10) and blood stasis endometriosis model group( n=50 ) . The blood stasis endometriosis model group was randomly divided into 5 groups after modeling: the Resina draconis. high-, medium-, and low-dose group, Guizhi Fuling group and model control group, 10 rats in each group.The Resina draconis. at 0.50, 0.25 and 0.12 g.kg-1 .d-1 was administered to the rats in the Resina draconis. high-, medium-, and low-dose groups, Guizhi Fuling capsule at 0. 25 g . kg-1 . d-1 to those in Guizhi Fuling group, and the same volume of 0. 5% sodium carboxyl methyl cellulose solution to those in model control group and blank control group. All treatments lasted for 3 weeks.At the end of the treatment, the rats were sacrificed;the volume and weight of ectopic tissue were measured. The blood viscosity was detected with blood rheometer.The concentration of estradiol and progesterone was detected using enzyme-linked immune sorbent assay.The matrix metalloprotein-2 expression in ectopic tissues was determined by RT-PCR. Results High, medium and low dose Resina draconis. significantly reduced the volume and weight of the ectopic tissue, and inhibited MMP-2 expression in ectopic tissues.High-, medium-dose Resina draconis. significantly reduced plasma cutting middle and low shear viscosity of the rats.But the Resina draconis. had no obvious effect on serum estradiol and progesterone concentration. Conclusion Resina draconis. reduces blood viscosity and inhibits MMP-2 expression, which can be used for the treatment of blood stasis type of endometriosis.

Objective To explore the effect of Cx43 protein on improvement of learning and memory ability induced by enriched environment (EE) in rats with traumatic brain injury (TBI). Methods TBI model was made by fluid percussion injury (FPI) in Sprague-Dawley rats. The TBI rats were divided into EE group (A), standard housing (ST) group (B), Cx43 specific antisense oligonucleotides (Cx43 ASODN)+EE group (C) and scrambled sequence ODN+EE group (D) with 6 rats in each group. Another 6 normal rats were taken as the control group. Groups C and D were given hippocampal microinjection of Cx43-ASODN (2 μl/d/rat, 1.5 mmol/L) and ScrbASODN (2 μl/d/ rat, 1.5 mmol/L) respectively. Morris water maze was used to evaluated the learning and memory ability. Results The latency was longer and the traversing times was less in group B than in the control group (P<0.05). The latency was shorter in group A than in group B (P<0.05), and there was no significant difference between group A and the control group (P>0.05) from the 9th day after injury. The traversing times was more in group A than in group B and there was no significant difference between group A and the control group (P>0.05). The latency was longer and the traversing times was less in group C than in group A (P<0.05). Conclusion Cx43 protein may participate in the improvement of the learning and memory ability induced by EE in rats with TBI.
