Chinese Journal of Tissue Engineering Research 2001;5(9):53-54
Objective The purpose of this study was to investigate the relationship between oxygen consumption (VO2) after recovery from incremental maximal exercise and the levels of the blood lactate (HLa), glucose and alanine metabolism. Method The VO2, HLa and plasma alanine were obtained using a modified version of Bruce' s protocol 30 min after exhaustion for 10 men. Result The VO2 after recovery has returned to the pre - exercise, but the HLa concentrations and plasma alanine were significantly increased from rest to maximal exercise, and were significantly decreased thereafter, but remained above resting values for 30 min after maximal stage. Conclusion we conclude that oxygen consumption after exhaustive maximal exercise is related to glucose resyntbesis through alanine metabolism, as compared with that from lactate metabolism.

AIM: To observe the protein expression of vascular endothelial growth factor 1 (VEGF-1) in pulmonary arterial endothelial cells and VEGF-1 gene expression in lung tissue in rats with hypoxia-induced pulmonary hypertension and treated with heparin. METHODS: Twenty four male adult SD rats were randomly divided into three groups (8 rats each): a control group (group A), a group with hypoxia for 4 weeks (group B) and a group with hypoxia for 4 weeks and injected with heparin to abdominal cavity simultaneously (group C). Mean pulmonary arterial pressure (mPAP), right ventricle hypertrophy index (RVHI) and vessel morphometry were measured. The morphology of pulmonary artery was observed by HE staining. The expression of VEGF-1 protein in pulmonary arterial endothelial cells was determined by immunohistochemistry. The level of VEGF-1 mRNA in lung tissue was measured by reverse transcription polymerase chain reaction (RT-PCR). RESULTS: mPAP, RVHI, pulmonary artery remodeling parameters, VEGF-1 protein expression in pulmonary arterial endothelial cells and VEGF-1 gene expression in lung tissue of the three groups from high to low were group B, group C and group A. It was statistically significant when compared between either two groups of the three (P<0.01). Linear correlation analysis showed that VEGF-1 protein was positively correlated with pulmonary artery remodeling parameters (r=0.974, P<0.01), and VEGF-1 mRNA was positively correlated with VEGF-1 protein (VEGF 120 mRNA, r=0.919, P<0.01; VEGF164 mRNA, r=0.896, P<0.01). CONCLUSION: Heparin may down-regulate the expression of VEGF-1 at the levels of transcription and translation, resulting in the inhibitory effect on rats with hypoxia-induced pulmonary hypertension.

OBJECTIVETo observe the clinical efficacy on cognitive impairment after traumatic brain injury (TBD treated with acupuncture and cognitive training.
METHODSSixty patients were randomized into an observation group and a control group, 30 cases in each one, and 5 cases of them were dropped out due to the earlier discharge. Finally, there were 28 cases in the observation group and 27 cases in the control group. In the control group, the cognitive training and conventional treatment were applied. In the observation group, on the basis of the treatment as the control group, acupuncture was applied to Baihui (GV 20), Fengchi (GB 20), Geshu (BL 17) and Fenglong (ST 40), once a day, for 4 weeks totally. The mini-mental state examination (MMSE) and Montreal cognitive assessment (MoCA) were adopted to evaluate the cognitive function in the patients of post-TBI cognitive impairment.
RESULTS(1) After treatment, the total score in MMSE and the score of each item were increased significantly as compared with those before treatment in the two groups (all P<0. 05). Except for the score of immediate recall, the score in MMSE and the score of each of the other items were increased significantly in the observation group as compared with those in the control group after treatment (all P<0. 05). (2)After treatment, the total score in MoCA and the score of each item were increased significantly as compared with those before treatment in the two groups (all P<. 05). Except for the score of nomenclature item, the total score in MoCA and the score of each of the other items were increased significantly in the observation group as compared with those in the control group after treatment (all P<0. 05).
CONCLUSIONBoth the simple cognitive training and the combined therapy of acupuncture and cognitive training improve MMSE and MoCA scores and relieve the cognitive impairment induced by TBI. But the combined therapy achieves the much better efficacy.

Objective To investigate the therapeutic effect of epigallocatechin gallate (EGCG) on the bladder neo-plasm induced by N-methyl-N-nitrosourea (MNU) in Wistar rats. Methods Seventy-two female rats were randomly divid-ed into two groups, treatment group and control group. The rat model of bladder tumor was established by intravesical instilla-tion of MNU (2mL/time, once every two weeks) inside bladder. Rats in treatment group were given EGCG (2 mL/time, once/day), and control group were given the same volume of distilled water. Six rats were executed respectively at the 3rd, 5th, 7th, 9th, 11th and 13th week, and the bladder histopathological changes were studied in two groups. Results The untypical hyper-plasia was observed after 5 weeks. The bladder neoplasm was observed at the 11th week in control group. The bladder neo-plasm was not found in treatment group. There was a significantly lower pathological score in treatment group than that of control group except for the first two weeks (P<0.05). Conclusion EGCG is effective for treatment of the bladder neo-plasm induced by MNU.
