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.

Hydronephrosis is a common and frequent clinical disease. With the extensive application of minimally invasive techniques of Western medicine, it can quickly remove the obstruction and eliminate water. However, there may be problems of easy recurrence after surgery, causing more serious irreversible kidney damage. TCM has a unique advantage in the treatment of hydronephrosis, which can radically relieve the pain of patients, prevent recurrence, and protect the kidney function. Professor SHAO Zhao-di thinks that the cause of hydronephros is deficiency of kidney qi, which affects the function of gasification. Therefore, the treatment should be nourishing qi to invigorate spleen and reinforcing kidney for diuresis. In clinical practice, Bixie Fenqing Decoction can be used to treat hydronephrosis, which can obtain good efficacy.

Objective To observe the in vitro effect of leptin, alone or in combination with tumor necrosis factor-alpha (TNF-α) on inducible nitric oxide (NO) and on inducible matrix metallo-proteinase-1 3 (MMP-13) in rabbit articular chondrocytes. Methods The chondrocytes from the articular cartilage of 2-month-old rabbits were cultivated and identified, and the second filial generation chondrocytes were cocultured on plates with different concentrations of leptin alone or in combination with TNF-α for 48 h or 96 h after 12 h starvation. The concentration of NO and MMP-13 was measured in the chondrocytes culture supernatant fluid. The results were statistically analyzed. Results There was no significant difference in the concentrations of NO between the different concentrations of leptin alone groups and the blank control group (P > 0. 05). In combination with the same concentration of TNF-α (10 ng/mL), leptin could dose-dependently increase the concentration of NO in the chondrocytes culture supernatant fluid in vitro. There was significant value in average concentration of MMP-13 on the main effect of both time and dose (P <0. 05) . No MMP-13 was detected in the blank control group. Conclusion Leptin can induce MMP-13 and have synergistic induction effect on NO with TNF-α in rabbit articular chondrocytes in vitro.
