Objective To observe the influencing factors of recurrence and metastasis for postoperative breast cancer high-risk population, and TCM regimen of syndrome differentiation and treatment was used to validate its significance for the prevention of recurrence and metastasis. Methods The influencing factors of recurrence and metastasis of 178 postoperative breast cancer high-risk cases with positive hormone receptor were studied. The recurrence and metastasis, disease-free survival and accumulative points of TCM symptoms of integrated group (with TCM syndrome differentiation and endocrine therapy) and western medicine group (with endocrine therapy) were compared. Results Lymph node metastasis, cancer staging and TCM therapy had influence on the disease-free survival rate of postoperative breast cancer high-risk patients. TCM therapy was the independent prognostic factor for disease-free survival. 3-year recurrence and metastasis rate was lower in integrated group than that in western medicine group, with statistical difference (P=0.03). The total accumulative points of TCM symptoms in both two groups decreased after treated for 3 and 6 months, integrated group showed greater significance. TCM therapy was better for the treatment of irritability, hot flash and perspiration, good for spontaneous perspiration and insomnia, but poor in dry mouth, bitter taste in mouth and fatigue. Conclusion Lymph node metastasis, cancer staging and TCM therapy are main influencing factors for recurrence and metastasis. TCM therapy with regimen of syndrome differentiation and treatment can reduce 3-year recurrence and metastasis rate, improve TCM symptoms, especially is significant for the improvement of irritability, hot flash and perspiration.

Objective To analyze the effect of conductive education combined with massage on activity of children with severe cerebral palsy. Methods 11 children (7 males and 4 females) with cerebral palsy receiving rehabilitation therapies in CereCare Wellness Centre of Xuhui, Shanghai from April to October 2010 were enrolled in this study. The type of cerebral palsy was as follows: 7 tetraplegia, 1 diplegia,2 athetoid, and 1 dystonia. The average age was 7.47 years, ranging from 4.7～11.9 years. The participants were divided randomly into 2groups. 5 children in group A accepted conductive education and massage therapy in the first 3 months, and then accepted routine rehabilitation therapies in the next 3 months. 6 children in group B accepted routine rehabilitation therapies in the first 3 months, and then accepted conductive education and massage therapy in the next 3 months. The phase of conductive education combined with massage was called intervention period, and the phase of routine rehabilitation therapies was called contrast period. The gross motor function was assessed with Gross Motor Function Measure Scale (GMFM), while the fine motor function was assessed with Fine Motor Function Measure Scale (FMFM).Pediatric Evaluation of Disability Inventory (PEDI) was used to assess activities of daily living. The different effects between conductive education combined with massage and routine rehabilitation therapies were compared. Results The scores of GMFM and FMFM both increased in intervention period, while both decreased in contrast period. The score of FMFM increased significantly (P<0.05). The scores of PEDI changed without statistical significance. Conclusion Conductive education combined with massage may increase the fine motor function of children with severe cerebral palsy compared with routine rehabilitation therapies.

This study aimed to investigate the effects of tannins extracted from Tibetan medicine Phyllanthi Fructus on cytochrome P450 enzyme of liver microsomes in rats.Cocktail probe substrates were incubated with liver microsomes in vitro.Metabolic elimination percentages of the six probe substrates,including dapsone,dextromethorphan hydrobromide,coumarin,phenacetin,chlorzoxazone and tolbutamide,were determined by HPLC.The effects of tannins extracted from Tibetan medicine Phyllanthi Fructus on the enzymatic activity of rat liver microsomal P450s was evaluated.It was found that tannins extracted from Phyllanthi Fructus did not impact P450 enzymes.The IC50 values of CYP3A4 and CYP1A2 were over 200 μg·mL-1,while the IC50 value of CYP2C9 was superior to 500 tg·mL-1.In conclusion,Tannins extracted from Tibetan medicine Phyllanthi Fructus did not significantly affect cytochrome P450 enzymes.

Objective To study the feasibility of DCE-MRI application in the orthotopic transplantation model of gastric cancer in nude mice.Methods Orthotopic transplantation model of gastric cancer in nude mice was established, and 15 models underwent DCE-MRI using the contrast agent of gadopentetate.Subsequently, the tumor was dissected in order to detect the MVD.The MVD was compared between orthotopic transplantation tumor model of gastric cancer and normal gastric mucosa.Results Fifteen nude mice with orthotopic transplantation of gastric cancer successfully underwent DCE-MRI examination.As for the cancer, the values of Ktrans, Kep and Ve were (2.11±0.44) min-1, (4.59±0.93) min-1, and 0.46±0.06, respectively.The MVD in gastric cancer tissues was significantly higher than that in normal gastric mucosa (χ2=16.205, P<0.001).Conclusion DCE-MRI can be used for noninvasively quantitative evaluation of vascular parameters of gastric carcinoma.

OBJECTIVE: To make an animal model of cervical spondylosis (arthralgia syndrome type) with stimulation of wind, cold, and dampness. METHODS: Twenty-four 8 months old male New Zealand white rabbits were randomly allocated into four groups: normal control group, light stimulation group, moderate stimulation group and severe stimulation group. The wind speed was 10.8-13.8 m/s, the temperature was (5+/-0.5)degrees centigrade, and the humidity was 100%. The rabbits of light, moderate, and severe stimulation groups were kept in the above-mentioned environments for 4 hours everyday, and for a total of 32, 64, and 128 hours, respectively. The intervertebral discs were stained with HE method, and observed with a light microscope. Prostaglandin E(2) (PGE(2)), 6-ketone-prostaglandin F1alpha (6-K-PGF(1alpha)) and thromboxane B(2) (TXB(2)) contents were measured by ELISA. Fas and Bcl-2 expressions were examined by immunohistochemical avidin-biotin peroxidose complex technique. Interleukin-1beta (IL-1beta), tumor necrosis factor alpha (TNF-alpha), and transforming growth factor beta (TGF-beta) mRNA expressions were examined by reverse transcription-polymerase chain reaction. RESULTS: The nucleus pulposus of rabbits in the light and moderate stimulation groups shrunken, and in the severe stimulation group, the anulus fibrosus loosed or ruptured, and the cartilage end-plate became proliferated. Compared with rabbits in the normal control group, the PGE(2) content rose in the light stimulation group, the contents of PGE(2), 6-K-PGF(1alpha), and TXB(2) increased, the expressions of IL-1beta and TNF-alpha mRNAs and Fas were up-regulated, and the expressions of TGF-beta mRNA and Bcl-2 were down-regulated in the moderate and severe stimulation groups. The expression of Fas was up-regulated mostly and Bcl-2 was down-regulated mostly in the severe group. CONCLUSION: Moderate and severe stimulations of wind, cold and dampness can lead to degeneration of cervical intervertebral discs of rabbits. The model corresponds to the theory of traditional Chinese medicine about arthralgia syndrome caused by wind, cold and dampness.
