Objective: To explore the relationship between the combinative intervention therapy and clinical curative effect, through used function magnetic resonance imaging (fMRI) to observe the change of detection data for patients with cerebral infarction pre and post-intervention therapy of acupuncture combined with traditional Chinese medicine (TCM). Methods: 40 patients with cerebral infarction were divided into control group (20cases, received normal treatment)and observation group (20cases, received combinative treatment of acupuncture and TCM). Pre and post therapy, the patients of every group received evaluation about state of illness and detection of fMRI. The score of national institute of health stroke scale (NIHSS) was used to evaluate the degree of neurologic impairment, and analyze the imaging manifestations of fMRI on patients with cerebral infarction at basal ganglia who received acupuncture combined with TCM. Some cerebral functional imaging techniques, included blood oxygenation level dependent( BOLD), fMRI and diffusion tensor imaging (DTI), were used to grasp the changes of relevant functional region of brain and different brain regions connected with function region of patients with cerebral infarction before and after therapy. Results: The NIHSS score of observation group was significantly less than that of the control group (t=5.450, P<0.05), and the total efficiency of observation group (95%) was significantly higher than that of the control group (75%) (x2=4.329, P<0.05). And the differences of the activation frequency, activation volume, ADCavg values and the values of FA between the observation group and the control group were statistically significant (t=5.425, 2.760, 3.453, 5.513, P<0.05). Conclusion: Acupuncture combined with traditional Chinese medicine can efficiently improve the status of neurologic impairment for patients with cerebral infarction, and the clinical efficacy before and after treatment can preferably be observed by fMRI.

Objective To assess the variation of salivary gland function in differentiated thyroid carcinoma (DTC) patients receiving different doses of 131 I therapy in the first.Methods 40 DTC patients were divided into two groups according to the application 131I doses,salivary scintigraphy was performed with 99TcmO4-on DTC patients before and 3months after 131 I therapy.Quantitative analysis of salivary gland function were performed.Results In low dose group,only the uptake ratio of 30min (UR30) of bilateral parotid decreased ( P ＜ 0.05 ) ; but in high - dose group,the uptake ratio of 30min (UR30),excretion fraction ( EF ),excretion rate (ER) of bilateral parotid and submandibular glands were significantly decreased,excretion time(EP) significantly prolonged after 131 I therapy( all P ＜0.05) ;the parotid gland was more severely than the submandibular gland.Conclusion Salivary gland function was damaged of DTC patients receiving different doses of 131I therapy in the first,salivary gland dysfunction correlated well with the administered dose.

Objective To investigate MVD, TSP-1, TGF-?1 expression in GH-Secreting Pituitary Adenomas by immunohistochemistry, and to correlate data with clinical characteristics.Methods The protein expression of TSP-1, TGF-?1 in 48 surgical specimens (21 invasive cases; 27 non-invasive cases) of pituitary adenomas was measured using immunohistochemical method. The relationship between the expression and clinical properties was examined. MVD was measured by detecting CD34.Results Compared with the noninvasive group, no difference of expression of CD34(t=2.257; P=0.083) was observed. The expression of TSP-1 in invasive group was low. The expression of TGF-?1 was higher in invasive cases than that in noninvasive ones. The expression of TGF-?1 had positive correlations with MVD; but there was no correlation between the expression of CD34 and the invasion of pituitary adenomas. In addition, MVD count was not associated with the expression of TSP-1. Size, sex or rate of recurrence did not influence MVD and TSP-1 expression. Conclusion MVD values do not necessarily represent angiogenesis in pituitary adenomas. TGF-?1 may increase MVD, and TSP-1 does not affect MVD in pituitary adenomas and angiogenesis may be regulated by other pathway.
