Angiogenesis is an important link of tumor growth, invasion and metastasis. The tumor angiogenesis targeting strategy for the treatment of cancer has become a hot spot in oncology research currently. Signal transduction of tumor angiogenesis is a complex, multi-factor, multi-way and cross network system. Treatment for a single target is often not sufficient to halt or reverse its highly heterogeneous structure and abnormal shape. Therefore, it will be an important research direction that the combination of different pathways and mechanisms of medications effect on signaling pathway in tumor angiogenesis by multi-target. A number of experimental studies found that qi-reinforcing and blood-activating medication can play a regulating role of multiple targets, multiple pathways in tumor angiogenesis. It had different effect on tumor angiogenesis against tumor invasion and metastasis.Qi-reinforcing and blood-activating medication will have broad prospects in the treatment of tumor and angiogenesis.

This study was aimed to observe the influence on migration ability of human umbilical vein endothelial cell (HUVEC) in vitro by couplet medicines of reinforcing qi and activating blood, and initially screen medicines with relative obvious promoting or inhibiting effect on migration ability of HUVEC. The model of HUVEC cultured in vitro was established. The Paeonia, Ligusticum chuanxiong, Cortex moutan, Salvia, curcuma zedoaria, Sparganium, Astragalus, and ginseng were combined in pairs with the proportion of 1:2, 1:1, 2:1. There were 13 couplet medicines of reinforcing qi and activating blood. Serum pharmacological method was used to prepare medicated serum of the couplet medicines of reinforcing qi and activating blood. Scratch method was used to detect the effect of medicated serum of these couplet medicines of reinforcing qi and activating blood and activate blood herbs on the migration a-bility of HUVEC (with the density of 5í105/mL) after 24 hours. The results showed that compared with the blood serum of the blank group, the Cortex moutan group, Ligusticum chuanxiong group, Paeonia group, Salvia and Astra-galus (1:2) group, Salvia and Astragalus (1:1) group, Ligusticum chuanxiong and Astragalus (1:2) group had obvious promoting effect on the migration ability of VEC (P < 0.05 or P < 0.01). The Sparganium group, curcuma zedoaria group, Cortex moutan group, curcuma zedoaria and Astragalus (2:1) group, Sparganium and ginseng (2:1) group, Spar-ganium and Astragalus (1:1) group had obvious inhibiting effect on the migration ability of VEC (P< 0.05 or P<0.01). It was concluded that different compatibility of medicines of reinforcing qi and activating blood and activate blood herbs had different promoting or inhibiting effect on migration ability of HUVEC. It may be related to the mechanism of action of these drugs on promoting or inhibiting angiogenesis at the cellular level.

This study was aimed to observe the influence of qi-reinforcing and blood-activating(QRBA) herbs onan-giogenesis of the myocardial microvascular, SDF-1 and CXCR4 protein expression as well as mRNA expression in the infarcted myocardium edge area of acute myocardial infarction (AMI) ratmodel. The AMI rat model was estab-lished. The immunohistochemical staining method was used in the detection of vWF protein expression in the myocar-dial tissues. The MVC account was recorded. The SDF-1 factor and its specific receptor factor CXCR4 were detected by the western blot and realtime-PCR technique in the infarcted myocardium edge area of rats from each group. The results showed that in the new generated microvessels which were staining marked by the vWF factor can be seen in infarcted myocardium edge area of rats from the sham-operated group, model group, each medication group. The new generated microvessels in the myocardium of rats in the sham-operated group were not obvious. Small amount of new generated microvessels can be seen in rats from the model group. More new generated microvessels can be seen in rats from each medication group. The comparison between the model group and the sham-operated group showed sta-tistical difference (P<0.05). The comparison between each medication group and the model group showed statistical difference(P<0.05 or P<0.01). Compared with the sham-operated group, SDF-1, CXCR4 and mRNA expression were obviously increased in the myocardium of rats in the model group (P<0.05 or P<0.01). Compared with the model group, SDF-1, CXCR4 protein and mRNA expression were obviously increased in the myocardium of rats from each medication group (P<0.05 or P<0.01). It was concluded that herbs such as Salvia, couplet herbs of Salvia and Astra-galushad stimulation effectonangiogenesis. Mechanism of these drugs in angiogenesismay be through the promotion of SDF-1 and CXCR4 protein as well as mRNA express.

Objective To discuss the method of the surgical treatment for retained and regenerate hepaticolithiasis, and to improve the theraputic level. Methods In recent 5 years,in our hospital,136 cases of retained and regenerate hepaticolithiasis were treated by combination of hepatolobectomy with other operation, and these cases were analyzed retrospectivly. Results One patient died after operation (0. 7%),8 patients had other complications including: biliary fistuta(6 cases, 4.4%), subphrenic abscess (2 cases,1.5%). All cases were visited for 2.5 - 8.3 years, 115 (84.6%) cases had not any symptom, 6 (4.4%)cases had infection of biliary tract, 6(4.4%) cases had retained calculus, 9(6.6%) cases recurred calculus 2 -5 years after operation. Conclusion Retained and regenerate hepaticolithiasis should be treated by combination of hepatolobectomy with other operation and fiber choledochoscope and B ultrasound of operation, which can increase therapeutic effect.

Because of many reasons, big changes occur in the varieties of ancient and modern Chinese herbs. Besides a significant increase in the number, there are many other features, such as significant differences among mainstream varieties, partly resolving the chaotic situation of uncoincidence of different herb names, increasing proportion of plant herbs, and herbal multi-polarization, etc.

Objective Using polysulfon fibers, a new bioartificial liver was developed. This study was to evaluate the efficacy of this bioartificial liver in the support of a disfunctioned liver. Methods Hepatocytes were procured from swine using Seglen′s methods. The bioartificial liver was constructed based on polysulfon bioreactor with a procurement of 10 10 hepatocytes, and was applied in 12 acute liver failure patients for 14 sessions. Each BAL treatment lasted 6 hours. The general conditions of the patients and the biochemical parameters were evaluated. Results After treatment with bioartificial liver, ammonia, prothrombin time and total bilirubin level significantly decreased (all P

Objective To investigate the effects of extract from couple medicinals of strengthening healthy qi and eliminating pathogenic qi, i.e.Huangqi(Radix Astragali, astragalus root) and Ezhu (Rhizoma Curcumae, curcumae rhizome), and oxaliplatin(L-OHP)on inhibiting metastasis of CT26 wild-type(CT26.WT)cells, and regulating CXCR3, CCR6 mRNA, and protein expression in rats with colon cancer.Methods Orthotopic transplantation model of BALB/c colon carcinoma was built in mice.L-OHP or L-OHP combined with extract from huangqi and ezhu were given to the mice model.Effects of those medicines on liver metastasis were observed.CXCR3 and CCR6 mRNA expression were measured by using RT-PCR, and CXCR3, CCR6 protein expression was detected with Western Blot.Results L-OHP group and L-OHP combined with Chinese medicinal groups exhibited inhibitive effects on orthotropic tumor growth, and best effect was observed in positive expression (P<0.01).L-OHP combined with TCM can decrease the incidence of liver metastasis (P<0.05).Compared with the control group, mRNA expressions of CXCR3 and CCR6 decreased in the model group and low-dose group (P<0.01).Effects of L-OHP combined with low-dose Chinese medicine were more effective than other groups(P<0.01).Compared with the control group, CXCR3 and CCR6 protein expressions decreased sinificantly in all groups(P<0.05 or P<0.01).Conclusion Mechanism of huangqi, ezhu and oxaliplatin(L-OHP) to inhibit tumor metastasis may relate to downregulation of CXCR3, CCR6 mRNA and protein expression.
