Objective To construct adenovirus vector with agiostatinK1-5 gene and to investigate the function of suppression to proliferation and migration for vascular endothelial cells.Methods With the use of gene recombination and clone technology, we constructed the adenovirus vector with the gene of angiostatin K1-5. In vitro vascular endothelial eclls proliferation assay and migration activity were performed through direct infection,MTT and transwell chemotaxis assay. Results 50% TCID indicated that the condence of resultant viruses was 1.5?109PFU/mL. It was purified by CsCL banding,final yield were generally 1.1?1010 PFU/mL plaquing-forming units. Through indirect infect assay and MTT, we found angiostatin K1-5 inhibited human vascular endothelial cells proliferation. We utilized human vascular endothelial cells to study the effect angiostatin K1-5 on cell migration,the result showed that adenoviruse vector with angiostatin K1-5 significantly inhibited HUVEC migration.Conclusion We successfully constructed adenoviruse vector with angiostatin K1-5 and demonstrated its inhibitory effect on proliferation andmigration of HUVEC.

Objective To discuss the clinical effect of neoadjuvant chemotherapy combined tumor cells to destroy the loss in treatment of patients with advanced ovarian cancer.Methods One hundred and forty-four patients with advanced ovarian cancer were divided randomly into the control group(n=72) and research group (n=72).The patients of control group were given conventional chemotherapy(ovarian tumor remove first and then neoadjuvant chemotherapy) and the patients of research group were given neoadjuvant chemotherapy (neoadjuvant chemotherapy first and then ovarian tumor remove).The operation time, intraoperative blood loss, hospital stay, ideal reduction rate, clinical efficacy and postoperative complications between the two groups were compared.Results The operation time, intraoperative blood loss, hospital stay of the research group were obviously lower than that of the control group((124.6±21.3) min vs.(186.4±32.6) min, (382.5±62.3) ml vs.(618.5± 86.4) ml, (8.9± 1.3) d vs.(12.2± 3.4) d;t =5.623,9.646,5.257), while the ideal reduction rate of the research group were obviously higher than that of the control group(70.8％ vs.47.2％, x2 =8.735), the differences were statistically significant(P＜0.05).The clinical efficacy(87.5％ vs.52.8％, x2 =6.748) of the research group were obviously higher than that of the control group, while the postoperative incision infection (9.7％ vs.19.4％, x2 =4.452) and fever(4.2％ vs.15.3％,x2 =5.536) were obviously lower than that of the control group, the differences were statistically significant (P＜0.05).Conclusion The treatment of neoadjuvant chemotherapy can obviously increase the the clinical effect of treatment of patients with advanced ovarian cancer and decrease the postoperative complications, it is worth popularization and application.

Atherosclerosis （AS） is a chronic inflammatory pathological process in which lipid and/or fibrous substances are deposited in the intima of arteries， and it is one of the pathological bases of many cardiovascular and cerebrovascular diseases. Endoplasmic reticulum stress （ERS） is a protective mechanism of cell adaptation. Moderate ERS can reduce abnormal protein aggregation and increase the degradation of misfolded proteins to repair and stabilize the internal environment， while excessive ERS can cause unfolded protein reaction， activate inflammation， oxidative stress， apoptosis， autophagy， and other downstream pathways， and lead to cell damage， or even apoptosis. A large number of studies have shown that ERS mediates a variety of pathological processes related to AS， affects endothelial cells， smooth muscle cells， macrophages， endothelial progenitor cells， and other cell components closely related to its occurrence and development， influences the progress of AS by regulating cell function， and promotes the formation of AS plaque， the transformation of stable plaque to unstable plaque， and the rupture of unstable plaque. Regulation of ERS may be a key target for the prevention and treatment of AS， and it is a research hotspot at present. Traditional Chinese medicine （TCM） believes that the origin of AS is the imbalance of Yin and Yang， the disharmony of Zangfu organs， and the abnormal operation of Qi， blood， and body fluid， which leads to the accumulation of phlegm， blood stasis， and other pathological products in the pulse channels， making the blood flow blocked or misfunction and causing the disease， which belongs to the syndrome of deficiency in origin and excess in superficiality. As the pathogenesis of AS is complex， and the symptoms are diverse， TCM has significant advantages in treating AS because of its multiple targets， multiple pathways， stable efficacy， strong individualization， and high safety. This paper systematically elaborated on the role of ERS in the occurrence and development of AS and summarized the mechanism research on the regulation and control of ERS by Chinese herbal monomer， Chinese herbal extract， Chinese herbal compound， and proprietary medicine， so as to provide a theoretical basis for clinical research and drug development in the prevention and treatment of AS.
