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.
4.Reseach on changes of varieties of ancient and modern Chinese herbs.
China Journal of Chinese Materia Medica 2011;36(13):1835-1838
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 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.

Objective To investigate the efficacy of Jianpiwenyang Gel(SSWYG)for treating chronic diarrhea and explore its therapeutic mechanism.Methods Eighty patients with chronic diarrhea of spleen and stomach weakness type were randomized into two groups for interventions with lifestyle adjustment and treatment with bifid triple viable capsules(control group,n=40)or naval application with SSWYG(treatment group,n=40)for one week,after which symptoms of chronic diarrhea were evaluated.The Chinese medicine system pharmacology analysis platform(TCMSP),GeneCards,NCBI,OMIM database and GEO database(GSE14841)were used to obtain the active ingredients and target proteins of SSWYG and chronic diarrhea-related targets.The key targets were obtained by topological analysis for Gene Ontology(GO)and KEGG analyses.The affinity and binding characteristics of SSWYG for specific targets were verified by molecular docking using AutoDock software.Results In both groups,gastrointestinal symptom rating scale(GSRS),Bristol Scale and TCM syndrome scores significantly improved after the treatments(P<0.05),and better effects were observed in the treatment group(P<0.05).Sixty-eight targets of SSWYG in treating chronic diarrhea were obtained,and 33 most probable ones were screened out by topological analysis.GO and KEGG analyses identified several chronic diarrhea-related pathways including the TNF and IL-17 pathways.Molecular docking study showed good affinity of the core components of SSWYG for the key targets CASP3,JNK,IL1B,IL6,and AKT1.JUN and CASP3 had the lowest binding energy and the highest stable binding energy with multiple major active ingredients of SSWYG.Conclusion SSWYG can significantly improve clinical symptoms of chronic diarrhea possibly by regulating the TNF and IL-17 as well as other pathways via CASP3 and JUN,suggesting a complex therapeutic mechanism of SSWYG involving multiple ingredients and targets and coordinated regulation of multiple pathways.
