Ischemic stroke is one of the main diseases which harm the health of the elderly. To promote angiogenesis is of great significance for treating ischemic stroke. In recent years, treatment by TCM based on therapeutic angiogenesis intervention for ischemic stroke has achieved great development. Pharmacological and clinical studies have shown that TCM can promote angiogenesis, thereby improving cerebral ischemia and neurological function. This article reviewed the current situation in this field and provided references for clinical treatment of ischemic stroke.

Objective To study the expression and significance of human tissue kallikrein gene 6(KLK6) in cervical cancer tissues.Methods With glyceraldehyde 3-phosphate dehydrogenase (GAPDH)as reference,the expression of KLK6 in 80 cases of cervical cancer tissues (40 cases with metastasis and 40cases without metastasis) and 40 cases of normal cervical tissues was determined by Taqman probe real-time quantitative reverse transcription-polymerase chain reaction,and analyzed the relationship between cervical cancer occurring and KLK6 expression with clinical data and pathological dats.Results The expression of KLK6 in normal cervical tissues[(1.06 ± 0.40) × 10-3] was lower than that in cervical cancer tissues without and with metastasis[(4.41 ± 1.70) × 10-3,(32.22 ± 6.70) × 10-3],and there was significant difference (P＜0.01).The expression of KLK6 in Ⅰ a,Ⅰ b,Ⅱ a stage of cervical cancer tissues with metastasis was (30.42 ± 5.00) × 10-3,(31.64 ± 1.30) × 10-3,(33.02 ± 8.00) × 10-3,and there was no significant difference among them (P ＞ 0.05).The expression of KLK6 in Ⅰ a,Ⅰ b,Ⅱ a stage of cervical cancer tissues without metastasis was (4.12 ± 1.10) × 10-3,(4.35 ± 1.30) × 10-3,(4.82 ± 1.90) × 10-3,and there was no significant difference among them (P＞0.05).There was significant difference in the expreesion of KLK6 in Ⅰ a,Ⅰ b,Ⅱ a stage between cervical cancer tissues with metastasis and cervical cancer tissues without metastasis (P ＜0.01).Conclusion KLK6 can stimulate the cervical cancer cell proliferation,and participate in the progresses of cervical cancer metastasis.

Objective To evaluate the therapeutic effects of combining acupuncture and physical therapy with drugs on treating Duchenne muscular dystrophy (DMD).Methods Sixty infants with DMD were randomly divided into a treatment group and a control group (n =30 in each).Both groups were injected with Bozhi glycopeptide and given levocamitine and fructose sodium diphosphate orally.Moreover,the treatment group was additionally given acupuncture and physical therapy.Before and after 90 days of treatment,the time to walk 10 metres and to climb stairs of 2 metres high was measured,as were the serum creatine phosphate kinase (CPK),lactate dehydrogenase (LDH) and aspertate aminotransferase (AST) levels of all participants.Results After treatment,the average walking and stair climbing times of both groups were significantly shorter,and those of the treatment group were significantly shorter than those of the control group.Moreover,the average CPK,LDH and AST levels in the treatment group were significantly lower than before treatment and than those of the control group after treatment.There was a significant difference in the overall response rates,with 93％ observed in the treatment group and 73％ in the control group.Conclusion Combining acupuncture and physical therapy with drugs can significantly increase the mobility and improve the serum CPK,LDH and AST levels of children with DMD.

Aim To observe the effect of methotrexate (MTX) on proliferation, migration and apoptosis of cultured vascular smooth muscle cells (VSMC). Methods Rabbit thoracaortic VSMC were cultured in vitro.VSMC proliferation was evaluated by cell counting and cell cycle analysis. Monolayer cell scrape was used to observe VSMC migration. Apoptosis was observed with flow cytometry, DNA gel electrophoresis and TUNEL stain. Results MTX (25～100 nmol?L -1) inhibited VSMC proliferation in a dose-dependent manner.25 nmol?L -1 and 50 nmol?L -1 MTX increased the percentage of the S phase cells and decreased the percentage of the G 2/M phase cells (P

AIM: To investigate the effects of Yiqi Huoxue prescription and Bushen Shengsui prescription on the expression of Notch-1 and Jagged1 protein in ischemic penumbra after local cerebral ischemia/reperfusion in intraluminal thread occlusion of the middle cerebral artery (MCAO) rats. METHODS: The local cerebral ischemia/reperfusion model was established by intraluminal thread occlusion of the middle cerebral artery. The animals were randomly divided into pseudo surgery group (sham group), model (MCAO) group, Yiqi Huoxue prescription (MCAO+Yiqi Huoxue) and Bushen Shengsui prescription (MCAO+Bushen Shengsui) groups. Using the techniques of immuno-histochemical staining, the expression of Notch-1 and Jagged1 was observed at 1, 2 and 3 weeks in ischemic penumbra of the cortex of frontal and parietal lobe. RESULTS: A value and positive unit of Notch-1 and Jagged1 protein expression in model group were higher than those in sham in ischemic penumbra of the cortex of frontal or parietal lobe after local cerebral ischemia/reperfusion in MCAO rats (P<0.05 or P<0.01). A value and/or positive unit of the expression in Yiqi Huoxue prescription and Bushen Shengsui prescription groups were lower than those in model group (P<0.05 or P<0.01). CONCLUSION: Yiqi Huoxue prescription and Bushen Shengsui prescription affect the proliferation and differentiation of neural stem cells, depress Notch signal transduction after local cerebral ischemia/reperfusion in MCAO rats by inhibiting the expression of Notch-1and Jagged1 protein.

OBJECTIVETo investigate the cystathione beta synthase (CBS) gene T833C, G919A, 844ins68 polymorphisms and plasma homocysteine (Hcy) levels in ethnic Uyghur and Han patients with essential hypertension (EH) in Xinjiang.

METHODSFour hundred twenty nine cases including 211 Uyghur and 218 Han EH patients were recruited, whilst 410 healthy individuals including 210 Uyghurs and 200 Hans were used as the controls. Amplification refractory mutation system (ARMS) was adopted to analyze the CBS gene polymorphisms including T833C, G919A and 844ins68. Enzymoimmunoassay was applied to determine the plasma level of Hcy. Chemiluminescence was applied to determine the plasma folic acid and vitamin B12.

RESULTSCompared with the controls, the plasma Hcy level was significantly higher in the EH group in both ethnic Uyghurs and Hans (P < 0.05). Plasma levels of Hcy in T833C, G919A genotypes (for both heterozygotes and homozygotes) were statistically higher than wild types (P < 0.05). A significant difference was detected in G919A polymorphism between the EH patients and controls in both Uyghur and [CM(144.5mm] Han ethnics (Uyghur: x² = 10.264, P < 0.01; Han: x² = 23.075, P < 0.01), and in T833C between the EH patients and controls in ethnic Uyghurs (x² = 40.254, P < 0.01). Logistic regression analysis indicated that age (OR=1.151, P=0.047, 95% CI = 1.002-1.323), T833C (CC) (OR = 1.078, P = 0.003, 95% CI = 1.043-1.114), obesity (OR = 1.284, P = 0.021, 95% CI = 1.038-1.590), hyperhomocysteine (OR = 3.296, P = 0.016, 95% CI = 1.244-8.733) were independent risk factors for EH among ethnic Uygurs, while age (OR = 1.162, P = 0.007, 95% CI = 1.042-1.297), obesity (OR = 3.501, P = 0.003, 95% CI = 1.521-8.060), hyperhomocysteine (OR = 1.046, P = 0.031, 95% CI = 1.011-1.459) were independent risk factors for EH in ethnic Hans after adjusting for confounding factors.

CONCLUSIONPlasma level of Hcy is associated with ethnic Uyghur and Han patients with EH in Xinjiang. CBS gene T833C CC genotype may be associated with the EH among Uyghur ethnics.
