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.

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.

ObjectiveTo establish a modified BISAP scoring system， and to investigate the value of the BISAP scoring system versus the modified BISAP scoring system in assessing the severity and condition of acute pancreatitis （AP）. MethodsFor the establishment of the new scoring system， a retrospective analysis was performed for the clinical data of 1 033 patients with AP who were admitted to Third Xiangya hospital of central South University from January 2019 to December 2021， and according to the revised Atlanta classification， they were divided into mild acute pancreatitis （MAP） group with 827 patients and severe acute pancreatitis （SAP） group with 206 patients. The two groups were compared in terms of clinical features， laboratory markers， and imaging data. A binary logistic regression analysis was performed for the statistically significant indicators to screen for the independent risk factors for SAP. The receiver operating characteristic （ROC） curve was used to obtain the optimal cut－off value corresponding to the maximum Youden index for each independent risk factor， and a score of 0 or 1 was assigned depending on different situations， which was integrated into the BISAP scoring system to establish a modified BISAP scoring system. For the validation of the new scoring system， a retrospective analysis was performed for the clinical data of 473 patients with AP who were admitted to Third Xiangya hospital of central South University from January 2017 to December 2018. BISAP score and modified BISAP score were determined for each patient， and the area under the ROC curve （AUC） was used to compare the value of the two scoring systems in predicting the severity and prognosis of AP. The chi－square test or the Fisher’s exact test was used for comparison of categorical data between two groups， and the independent－samples t test and the Mann－Whitney U test were used for comparison of continuous data between two groups. ResultsFor the establishment of the new scoring system， there were significant differences between the MAP group and the SAP group in mode of admission， length of hospital stay， ICU admission rate， number of deaths， underlying diseases， and incidence rate of complications （all P<0.05）. The binary logistic regression analysis showed that body temperature， neutrophil－to－lymphocyte ratio （NLR）， C－reactive protein （CRP）， albumin， triglycerides， D－dimer， fibrinogen， and MCTSI score were independent risk factors for SAP （all P<0.05）. The ROC curve analysis showed that CRP （AUC=0.921）， NLR （AUC=0.798）， D－dimer （AUC=0.768）， and MCTSI score （AUC=0.931） had a good predictive value for SAP， and the combination of these four indicators had an AUC of 0.976 and showed a significantly higher diagnostic efficiency than each indicator alone or the combination of two or three indicators （all P<0.05）. For the validation of the new scoring system， a total of 473 patients were enrolled， with 408 in the MAP group and 65 in the SAP group， and there were significant differences between the two groups in mode of admission， length of hospital stay， ICU admission rate， number of deaths， and incidence rate of complications （all P<0.05）. The modified BISAP score was better than the BISAP score in predicting SAP （AUC： 0.972 vs 0.887， P<0.05）， with an optimal cut－off value of >3 points. The modified BISAP score also had a relatively high value in predicting the mortality of AP patients （AUC=0.910）， but there was no significant difference between the modified BISAP score and the BISAP scoring system （AUC： 0.910 vs 0.896， P=0.707）. ConclusionThe modified BISAP score is better than the BISAP score in predicting the severity of AP and has a relatively high value in predicting the mortality of AP patients， giving a more accurate， objective， and early assessment of the condition of AP patients.
