Objective: To investigate the vascular protective mechanism of different levels of herbs through detecting activity of HO-1/CO system in arterial tissues of rats with stagnancy of collateral-Qi in deficiency condition. Methods: Healthy male Wistar rats of cleanness level were randomly divided into control group, stagnancy of collateral-Qi in a deficiency condition group (SCQDC group), Renshen group, Shuangshen group, and Tongxinluo group. The ultrastructure of endothelium cells in the artery was observed. RT-PCR, Western blot, and immunohistochemical approaches were used to detect JNK, c-Jun mRNA and albumen expression in the arterial tissues. Meanwhile, the content of CO in the arterial tissue was also detected. Results: In SCQDC group, the counts of pinocytotic cells and microvili on the free surface of vascular endothelial cells were significantly decreased; most crests of mitochondria fused with membrane, some even disappeared; serious degranulation was observed in the rough surfaced endoplasmic reticulum. Immunohistochemistry showed that the HO-1 positive signals in the arterial histiocyte weakened significantly compared with the control group. The HO-1 expression was increased in the 3 treatment groups. Compared with control group, SCQDC group had decreased HO-1 mRNA and albumen expression(P<0.01,P<0.001). The 3 different kinds of Herbs to dredge collaterals increased the HO-1 mRNA and albumen expression to different degrees (P<0.001). The increase of albumen in the Tongxinluo group was more than those in the Shuangshen group and the Renshen group(P<0.001). Tongxinluo also significantly increased the CO content. Conclusion: Herbs to dredge collaterals can induce CO production by ameliorating or recovering the HO System, which may be one of the mechanisms for protecting the vascular tissues.

Objective To provide a clinical anatomic basis for the bi-pedicled gastrocnemius myocuta- neous flap which is to be used to repair defects of the Achilles tendon and posterior skin of the ankle.Methods In anatomic study,out of 30 cadaver specimens,bi-pedicled V-Y gastrocnemius myoeutaneous flaps were harvested to measure the downward sliding lengths of the flap when the knee was at flexion of different degrees.In clinic,12 patients with the Achilles tendon and posterior ankle skin defects were repaired with the bi-pedicled gastrocnemius myocutaneous flaps.The areas of composite defects ranged from 10 cm?6 cm to 6 cm?4 cm.They were followed up for four months to 12 years.Results The maximal sliding length of the flap reached (9.2?0.9)cm when the knee was at flexion of 90?.All the clinical flaps survived and ambulation of the patients recovered.The dorsiflexion and plantarflexion of the ankles reached 11.0??1.4?and 35.0??4.6?respectively.Conclusion This flap is suitable for one-stage repair of composite Achilles tendon defects.

Objective To observe the clinical effect of abdominal Tuina and acupuncture in treating Swiss generalized anxiety disorder (GAD). Methods 80 patients of GAD caused by liver depression-qi stagnation were randomly recruited into a treatment group and a control group, 40 patients in each. The treatment group was treated with abdominal tuina & acupuncture; while the control group was treated with acupuncture exclusively. Clinical effects and hamilton anxiety scale (HAMA) score were observed in both groups before and after the treatment. Results ①There was significant difference in total efficacy between the two groups CP<0.05), and the treatment group was better than the control group. ②The HAMA score of the two groups after the treatment was lower than that before the treatment, and the difference was significant (P< 0.05). There was also significant difference of HAMA score between the two groups after the treatment (/><0.05), with the treatment group showing better results than the control group. Conclusion Abdominal tuina combined with acupuncture has sound effects in treating Swiss GAD due to liver depression-qi stagnation.

OBJECTIVETo explore the clinical effect and therapeutic mechanism of Kangxian Baogan Decoction (KXBGD) on liver fibrosis caused by chronic hepatitis B.

METHODSEight-one patients with chronic hepatitis B were divided into two groups randomly. The 54 patients in the treated group were treated by KXBGD and the 27 patients in the control group were treated by conventional liver protecting treatment. Serum levels of hyaluronic acid (HA), procollagen type III (PC III), collagen type IV (C-IV), laminin (LN), transforming growth factor beta 1 (TGF beta 1) and tumor necrosis factor-alpha (TNF-alpha) were measured before and after treatment, meanwhile, liver function and pathological changes of liver tissues were observed.

RESULTSThe total effective rate in the treated group was significantly higher than that in the control group. Serum levels of HA, PC III, C-IV, LN, TGF beta 1 and TNF-alpha in the treated group obviously reduced after treatment, and the liver function got better with significant difference as compared with those in the control group (P < 0.05 or P < 0.01). Pathological examination of liver biopsy showed that the fibrous tissue in the liver reduced.

CONCLUSIONKXBGD has a definite effect of anti-liver fibrosis.

For the establishment of chemical library of protoberberines provided for the bio-activity screening, the target compounds were synthesized by thermal degradation and nucleophilic substitution reactions with the bio-active alkaloid, palmatine (1), as the raw material, and their structures were identified and conformed by 1H-NMR and MS spectra. Among them, 13 compounds were new.

OBJECTIVETo investigate the effect of Tongxinluo capsule (TXLC) on the patients with unstable angina pectoris (UAP).

METHODSPatients of UAP were divided into two groups, the treated group (n = 60) was treated with TXLC and the Danshen group (n = 30) was treated with composite Danshen tablet. The plasma endothelin (ET) and calcitonin gene related peptide (CGRP) were measured before and after treatment. Data were compared between the two groups and also compared with those measured in 20 healthy subjects for control.

RESULTSET level was higher and CGRP level lower significantly in UAP patients than that in healthy subjects significantly (P < 0.05). After TXLC treatment, ET significantly lowered (P < 0.01) and CGRP increased (P < 0.05). But in the Danshen group after treatment, the former decreased (P < 0.05), while the latter remained unchanged (P > 0.05). The effect of TXLC was better than that of composite Danshen tablet.

CONCLUSIONTXLC is an effective drug for UAP treatment, which could efficiently regulate the ET and CGRP metabolism and ameliorate the degree of myocardial ischemia damage.

Objective To observe the distribution of bone marrow mesenchymal stem cells(MSCs) and the effects on expression of apoptosis relative proteins Caspase 3 and Bcl-2 after intravenous transplanted into ischemic rat brains.Methods MSCs from SD rats were cultivated and proliferated in vitro and marked with CFSE.MSCs were then intravenously transplanted into middle cerebral artery occlusion(MCAO)models of SD rats.The rats were killed at different time points to observe the distribution of MSCs under fluorescence microscoDe as well as the effects on expression of apoptosis relative proteins Caspase 3 and Bcl-2 using immunohistochemical method.Results Density of Caspase 3 in immunohistochemically positive area in transplantion group were(2.81±0.35)%,(3.98±0.67)%,(5.58±0.92)%,(3.51±0.63)%,(1.64±0.29)%in 6,12,24,72 hours and in 7 days,respectively,and decreased significantly compared with those of control group[(3.92±0.44)%,(5.23±0.30)%,(6.89±0.57)%,(4.39±0.57)%,(2.29±0.21)%],the difference being significant(t=4.37,3.34,2.60,2.32,3.90,P＜0.05 or＜0.01).The density of Bcl-2 in immunohistochemically positive area in transplantation group were(4.70±0.16)%,(5.61±0.26)%,(3.00±0.28)%respectively in 6,12 hours and in 7 days,which had improved significantly compared with those of control group[(3.28±0.27)%,(4.54±0.59)%,(2.15±0.62)%],the difference being significant(t=8.32,3.25,2.54,P＜0.05 or＜0.01).Conclusions Bone marrow MSCs can exert protective effects on brain ischemia and reperfusion injury possibly by down-regulating Caspase 3 and up-regulating Bcl-2.
