Objective To observe the effects of thin recipe ofBuyang Huanwu Decoction on expressions of glutathione (GSH) antioxidant system including GSH, GSH-Px andγ-GCS in the brain of focal cerebral ischemia rats;To study its mechanism of antioxidant effect.Methods Totally 120 SD rats were randomly divided into four groups according to random number table method:sham-operation group, model group,Buyang Huanwu Decoction group and thin recipe ofBuyang Huanwu Decoction group. Except for the sham-operation group, the rest groups established focal cerebral ischemia rat model by middle cerebral arterial occlusion. The treatment groups were given corresponding medicine by gavage, while the sham-operation group and model group were given the same amount of normal saline 2 h after modeling. Each group was detected after cerebral ischemia for 1 day, 3 days, and 7 days respectively. The content of GSH and the activity of GSH-Px were detected. At the same time,γ-GCS mRNA and protein levels were determined by using real time-PCR and Western blot.Results The content of GSH and the activity of GSH-Px at each time point decreased in the model group (P<0.05), compared with the corresponding sham-operation group. But the expression ofγ-GCS mRNA and protein increased, with statistical significance on day 1 (P<0.05). Compared with model group, content of GSH and GSH-Px activity levels increased differently in each treatment group, whileγ-GCS mRNA and protein expression raised, with statistical significance on day 3 (P<0.05).Conclusion The thin recipe ofBuyang Huanwu Decoction plays antioxidant effect by regulating the expression of glutathione antioxidant system GSH, GSH-Px andγ-GCS after cerebral ischemia, which may be one of its therapeutic mechanisms for cerebral ischemia.

OBJECTIVETo obtain postoperative desirable appearance of the deformed breast we apply Mckissock reduction mammaplasty technique in treatment of giant benign breast tumor.

METHODSAccording to the principle of Mckissock reduction mammaplasty technique, we design a special incision to remove the tumor in company with the proceeding of mammaplasty.

RESULTS11 cases of operation with satisfactory results for giant benign tumors have been performed since 1993.

CONCLUSIONSStandard reduction mammaplasty technique has turned out to be an effective remedy for giant tumor spoiling the appearance of the breast.

OBJECTIVETo introduce an improved technique for Macrocheilia. The traditional technique for macrocheilia with direct suture and Z-plasty was improved to decrease postoperative complications, e.g. dynamic abnormality, obvious scar and recurrence due to scar contraction.

METHODSOutside of the new commissure, a triangle flap of the upper lip vermilion was designed, created and inserted to the lower lip. The orbicularis oris muscle was anatomically replaced. Skin Z-plasty was made with triangle flap transferring from the upper to the lower instead.

RESULTSSince August 1985, the new technique has been used in 12 cases of Macrocheilia. All the patients obtained satisfactory results with nice configuration and good function without dynamic abnormality and obvious scar.

CONCLUSIONThe new technique is a more reasonable method for macrocheilia with nice configuration, good function and fewer complications.

Aim To evaluate the regulation of thin recipe of Buyang Huanwu decoction on cyclin-dependent kinase 5(Cdk5)expressions in hippocampus tissue of rats after cerebral ischemia.Methods Male SD rats were divided into sham-operation group,MCAO group,Buyang Huanwu decoction group(ig.3.15 g·kg-1)and its thin recipe composition group(ig.2.41 g·kg-1).Each group was then divided into five subgroups based on the time after administration for 1,3,7,14,28 d respectively.Cdk5 protein and mRNA levels in each group were examined by using immunohistochemistry,Western blot and real-time PCR respectively.Results The up-regulation of Cdk5 was observed in model rat hippocampus after cerebral ischemia 1 day,and kept increasing with the aggravation of ischemia injury,the peaked expression was observed after 7～14 d,while the downtrend was observed after 28 days compared with the corresponding sham-operation groups(P<0.01),suggesting that the Cdk5 signal pathway would be activated by cerebral ischemic injury.The expression of Cdk5 in thin recipe of Buyang Huanwu decoction group was significantly lower than that in model group at each time point(P<0.05),and there was also more obvious down-regulation with the extend of intervene time.The regulation effects of thin recipe of Buyang Huanwu decoction was up to the best after 28 days of administration,which indicated the thin recipe was positive to the abnormal expression of Cdk5,and there was no difference between Buyang Huanwu decoction and its thin recipe treated groups(P>0.05).Conclusion The thin recipe of Buyang Huanwu decoction could exert the protective effect by regulating Cdk5 after cerebral ischemia.

Aim To observe the effects of thin recipe of Buyang Huanwu Decoction on angiogenesis and the signal pathway of Nrf2 / HO-1 after cerebral ischemic injury in rats. Methods Totally 120 SD rats were randomly divided into four groups: sham operation group,model group,Buyang Huanwu Decoction group and thin recipe of Buyang Huanwu Decoction group. The focal cerebral ischemia rat model was established by middle cerebral arterial occlusion. Each group was treated with corresponding treatment. Each group was detected after cerebral ischemia for day 1,day 3 and day 7, respectively. Immunohistochemical method was used to detect the plasma levels of factor VIII related antigen( vWF), determination of microvessel density (MVD). The expression of Nrf2,HO-1 gene and pro-tein in brain tissues was detected by Real-Time PCR (RT-PCR) and Western blot. Results ① Compared with sham-operation group, the expression of vWF in the model group was significantly increased on day 3(P< 0. 05). Compared with model group, the expression levels increased differently in each drug group on day 7 (P < 0. 05). ② The expression of Nrf2, HO-1 gene and protein in sham operation group showed a small a-mount of gamma expression. Compared with sham op-eration group at the same time point, the expression of Nrf2 protein was significantly increased on day 3(P <0. 01). Compared with model group at the same time point, the Nrf2mRNA and protein expression was up-regulated in each drug group. The Nrf2mRNA on day 1,the Nrf2 protein on day 1 and day 7 were significant-ly increased( P < 0. 01). Compared with sham opera-tion group at the same time point, the expression of HO-1mRNA and protein in the model group was signif-icantly increased on day 7(P < 0. 05). Compared with model group at the same time point, the HO-1mRNA on day 3, the HO-1 protein on day 3 and day 7 in each drug group were significantly increased (P < 0. 05,P <0. 01). Conclusions The thin recipe of Buyang Hua-nwu Decoction promotes brain angiogenesis after ische-mia. The effect may be related wih the expression of Nrf2 / HO-1 signal pathway.
