Aim To investigate the treatment effect of Tongxinluo(TXL)combined peripheral blood derived mesenchymal stem cells(PB-MSCs)transplantation on angiogenesis of HIF-1 /VEGF pathway and miR-21 0 in diabetic foot(DF)rats.Methods Seventy male Spra-gue-Dawley rats were fed with high-fat diet and given
combined streptozotocin injection to build diabetic rat model.The femoral artery and vein of right lower ex-tremity of modeled rats were ligatured to induce DF model.The normal rats in the same batch copied is-chemia model served as control group.The modeled rats were divided into 6 groups :model group ,TXL
group,Cilostazol group,PB-MSCs group,TXL com-bined PB-MSCs(T-MSCs)group and Cilostazol com-bined PB-MSCs(C-MSCs)group.After the treatment for 28 days,animal gastrocnemius muscle and serum were taken for detection,in which serum was used to detect VEGF-A and HIF-1 α by ELISA,and muscle was used to detect VEGF-A and VEGF-R2 by Western blot,and VEGF-A by RT-PCR.Results Compared with the control group,the expressions of VEGF-A, HIF-1 α,VEGF-R2 and miR-21 0 in the model group were significantly reduced(P <0.01 ).Compared with the model group,the expressions of VEGF-A,VEGF-
R2 and miR-21 0 in each treatment group were signifi-cantly increased(P <0.01 ),where the expressions of VEGF-A,HIF-1 α,VEGF-R2 and miR-21 0 in the T-MSCs were higher than these in the TXL,cilostazol and PB-MSCs group(P <0.05,P <0.01 ).Conclusion TXL combined with PB-MSCs transplantation may be regulated by HIF-1 /VEGF pathway and miR-21 0,pro-moting endothelial cell proliferation,differentiation, and promoting the formation of new blood vessels.

Objective To investigate the onset and risk factors of the transient ischemic attack of vertebrobasilar artery vertige in old patients. Methods Patients were divided into group A, group B, group C based on attack times of vertige and whether cerebral thrombosis was formed within half a year. Blood biochemistry index, blood pressure variation, carotid ultrasonic examination results in the first 24 hours were compared. Results High sensitive C-reactive protein (hs-CRP), systolic blood pressure (SBP), diastolic blood pressure(DBP), blood sugar(BS), cholesterol(TC), triglyceride(TG), common carotid artery resistance of group A index(CCARI), internal carotid artery resistance index(ICARI) and atherosis plaque index in the first 24 hours were significantly lower than those of group C (P0.05). Logistic regression indicated that hs-CRP, DBP, BS, TC, CCARI, ICARI and plaque index were correlated with risk factors of the transient ischemic attack of vertebrobasilar artery vertige and cerebral thrombosis in old patients. Conclusion hs-CRP, SBP, BS, TC, CCARI, ICARI and plaque index elevation might be an early warning index for the unstability and easy drop of the carotid's plaque.

The pathogenesy of diabetic peripheral neuropathy(DPN) is approached according to collaterals diseases theory in this study,indicated that defi ciency of both vital energy and yin is the chief pathologic foundation and obstruction of collaterals by blood stasis and phlegm is the critical element in DPN.Furthermore,highlight of differentiation of symptoms and signs,therapeutic principle and diagnosis and treatment based on differentiation are illuminated.This study has supplied a new idea for precaution and treatment of DPN.

AIM: To observe the different changes of neuroendocrine systems between the state of sport fatigue and poverty of movement. METHODS: 60 male Wistar rats were randomly divided into three groups: normal control group, sport fatigue model group and poverty of movement model group (20 rats in each group). The sport fatigue model was established by the method of combining basal diet and loaded swimming during 2 weeks, whereas the method of restricted activities was used to establish the poverty of movement model with total experimental time of 10 weeks. By the end of experiment, the climbing pole time was determined. The contents of hypothalamus thyrotropin releasing hormone (TRH), and serum norepinephrine (NE) and epinephrine (E) in rats with different treatments were determined by ELISA. In addition, the changes of hypothalamus corticotropin release hormone (CRH), pituitary adrenocorticotropic hormone (ACTH) and thyroid stimulating hormone (TSH), and serum corticosterone (CORT), triiodothyronine (T_3), tetraiodothyronine (T_4) were determined by radioimmunoassay to evaluate the functions of adrenergic nerve-adrenomedullin system, hypothalamo-pituitary-adrenal (HPA) axis and hypothalamo-pituitary-thyroid (HPT) axis. RESULTS: Compared to control group, the climbing pole time of the animals was obviously decreased in two model group. The adrenergic nerve-adrenomedullin system and HPA axis were inhibited in sport fatigue model rats, but HPT axis was unchanged. Interestingly, the HPA axis was hyperfunctional and HPT axis was inhibited in poverty of movement model rats. However, no change in the adrenergic nerve-adrenomedullin system was observed. CONCLUSION: Sport fatigue and poverty of movement all affect neuroendocrine system and lead to the adjustment mechanism imbalance, but the target and tendency are different.

OBJECTIVE: To explore the pathogenesis characteristics of variant angina pectoris (VAP) by extracting its syndrome elements and analyzing the combination and distribution regularity of the syndrome elements. METHODS: One hundred and seventy-five case files of VAP patients were collected. The extraction of syndrome elements and symptom contribution to syndrome was completed by the partition method of complex system based on entropy theory. Diagnostic threshold was established by receiver operator characteristic curve. According to the results diagnosed by diagnostic criteria for syndrome element with quantitation, the combination and distribution regularity of the syndrome elements in patients with VAP was analyzed. RESULTS: The basic syndrome elements in the patients with VAP were qi deficiency, qi stagnation, blood stasis, phlegm turbidity, phlegm-heat, stagnation-heat, yin deficiency and yang deficiency syndromes. It showed that the combination types of syndrome elements could be made up of one syndrome, two, three, four or more than four syndromes. Qi deficiency, yin deficiency, qi stagnation, blood stasis and phlegm turbidity syndromes had the higher frequency than other syndrome elements in the patients with VAP. CONCLUSION: The partition method of complex system based on entropy theory can be used in extracting the syndrome elements of the patients with VAP. It is found that VAP has complicated pathogenesis according to the combination and distribution regularity of syndrome elements. Qi deficiency, qi stagnation, blood stasis, phlegm turbidity and yin deficiency syndromes are the main syndrome elements.
