Breast cancer (BC) is the most common cancer of women worldwide. Over the past 20 years, the incidence and mortality rates of BC have increased and have ranked the first place of the female cancer in our country. In the theory of traditional Chinese medicine (TCM), etiology and pathogenesis of BC have long been recognized. Base on these basic theories, TCM physicians have developed their typical opinions on BC treatment. Liver depression has been considered as the key point and the main syndrome type in BC syndrome differentiation. It showed the impor-tance of liver depression syndrome in breast cancer and provided ideas for clinical treatment. With the development of modern science, several experimental and clinical studies have found that liver depression syndrome is closely related to BC. Further study on liver depression syndrome in BC procession may not only helpful to screen high-risk BC groups and improve the early diagnosis rate but also helpful to find new drug targets.

Objective To study the neuropsychological behavior development of preterm infants and low birth weight infants,and to provide a reference to the early prevention and intervention on developmental retardations.Methods A total of 101 preterm infants and/or low birth weight infants received the infant development test of 0 ～ 6 year-old children intelligence developmental scale for neurological development and autism behavior checklist(ABC).Results 25 boys and 5 girls suffered from different psychological mental disorders.The occurrences were as follows:10 cases with mental retardation,9 cases with the language development delay,9 cases with motor retardation,1 case with cerebral palsy and 1 case with autism spectrum disorder.The incidence of intelligence problems were that language retardation (18.9％),the fine motor (16.8％),the adapative ability (12.6％),social action (9.5 ％) and the motor delay (3.2％).There were significant differences in the scores of social communication(x2=8.88,P=0.003),adaptive ability(x2=7.41,P=0.007),the fine motor(x2 =6.22,P=0.01) and total developmental quotient(x2 =5.58,P=0.02) between city children'and rural area.The behavioral problems more consisted in self-care ability and language retardation.Conclusion Preterm infants and low birth weight infants are exposed to language,fine motor,adaptive and communication ability problems,especially the children living in country.It is necessary to improve the early education and intervention for the rural preterm infants and low birth weight infants.

Objective To investigate the hemodynamic changes in cirrhosis rats after orthotopic liver transplantation. Methods The cirrhosis model was constructed in 50 healthy male SD rats by intraperitoneal and subcutaneous injection with carbon tetrachloride (CCl_4), and induced by drinking alcohol solution for 10 weeks. Orthotopic liver transplantation with two-cuff technique was adopted to these rats. The hemodynamic changes were observed. Results Cirrhosis model was constructed in 36 rats, 26 of which then received liver transplantation. Finally 12 cirrhosis rats survived, and hemodynamics of portal vein were observed. The statistical analysis revealed that the portal venous pressure decreased significantly after the operation compared with pretransplant [(1.60±0.10)kPa vs. (1.70±0.25)kPa, P<0.05]; the portal vascular resistance increased significantly [(7.55±1.02)mL/min vs. (6.15±0.88)mL/min, P<0.05]; however, the portal venous flow decreased obviously[(11.84×10~(-2)±2.51×10~(-2))kPa/(mL·min)vs.(16.29×10~(-2)±2.40×10~(-2))kPa/(mL·min),P<0.05-.Conclusion The hemodynamics of cirrhosis rats ameliorate after rthotopic liver transplantation.

OBJECTIVETo explore the working mechanism and age-related change of the conflict processing system of the frontal cortex.

METHODSFifteen normal elderly people and 15 youth were performed a modified Eriksen flanker paradigm, while event-related potential (ERPs), which include 32 systerm electroencephalography, reaction time and correct rate were recorded.

RESULTSThe elderly group showed a distinct effect of reaction time and effect of conflict in the respond level compared with the youth group. The elderly group had a longer time window of N380 and same amplitude as the youth group. Low resolution brain electromagnetic tomography (LORETA) showed the bilateral temporal lobe and the dorsolateral prefrontal cortex (especially right) were activated in the youth group, while the left temporal lobe, the left dorsolateral prefrontal cortex and left medial frontal gyrus were activated in the elderly group.

CONCLUSIONWhen conflict stimuli existed in the response level, old people showed frontal interference control hypofunction. N380 reflected the activation of the left dorsolateral prefrontal cortex and the left temporal lobe during response selection and executive control processing in older people.

Objective To evaluate the effectiveness and safety of Shuangyi Qushi Tongluo Capsules ( SQTC) in treating ankylosing spondylitis (AS), and to explore the synergistic action of SQTC combined with sulfasalazine. Methods A randomized and parallel-controlled trial was carried out in 80 AS patients. The enrolled subjects were evenly randomized into testing group and control group. Both groups were given oral use of sulfasalazine enteric-coated tablets, and the testing group was additionally given oral use of SQTC, which is mainly composed of silky ant (Formica Fusca), black-winged Termitidae, Scorpio, Radix Ginseng, Radix Astragali, Rhizoma Atractylodis Macrocephalae, Radix Angelicae Sinensis, Flos Carthami, Radix Salviae Miltiorrhizae, Radix Achyranthis Bidentatae, Caulis Spatholobi, Herba Epimedii, and Radix Morindae Officinalis. The treatment for the two groups covered 24 weeks. On treatment week 4, 12, 24, we recorded the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), visual analog scale (VAS) scores of rachialgia, patients’ general assessment (PGA), VAS scores of night pain, spondylitis scores, Bath Ankylosing Spondylitis Functional Index ( BASFI) , Bath Ankylosing Spondylitis Metrology Index ( BASMI) , scores of the quality of life ( QOL) , erythrocyte sedimentation rate ( ESR) , C-reactive protein ( CRP). Moreover, the adverse reaction of the two groups was also monitored. Results ( 1) Compared with the control group, testing group had high ASAS 20 percentage on treatment week 4, 12 and 24 (P<0.05 or P<0.01). (2) After treatment for 12, 24 weeks, the observation indexes were much improved in the testing group ( P<0.05 or P<0.01 compared with the control group). ( 3) In the control group, one case ( 2.86%) had slight abnormal hepatic function, and one case (2.63%) in the testing group had slight gastrointestinal discomfort, the difference being insignificant (P>0.05). Conclusion SQTC are effective and safe in treating AS, starting an effect shortly and having synergistic effect on salfasalazine for the treatment of AS.

To clarify the source of deviations of drug combination effects evaluated with different drug interaction mathematical models, the cytotoxicity of SAHA and arsenic trioxide and their combinations were observed in a series of human cancer cell lines and a normal cell line. The combined effects were evaluated with three drug interaction models: Loewe Additivity (LA), Bliss Independence (BI) and Chou's Median Effect Model. The evaluations with three different models were further compared with each other. We demonstrated that when dose-response curves were fitted with the same method, similar evaluated results for drug combinations would be derived with different models. The deviations of evaluated effects of drug combinations were attributed to different curve fitting methods used rather than the models themselves. The effects of drug combinations showed discrepancies on different cell lines, and at different combined drug concentrations on same cell line.

Objective To investigate the effect of transforming growth factor-?1 (TGF-?1) on the activity of connective tissue growth factor(CTGF) gene promoter in human renal proximal tubular epithelial cell line HK-2.
