Objective:To study the effect of exogenous hyaluronidase on proliferation of human breast cancer cells in vitro.Methods:The proliferation of human breast cancer cell line ZR-75-30 were detected by MTT-assay and flow cytometry.Results:The absorbency value(A) of ZR-75-30 in study group treated with Hyase (0.674?0.221) was significantly higher than that in control group(0.563?0.046).The percentage of phase S cells in study group(18.36?0.65) was higher than that in control group(2.19?0.10);the percentage of phase G0/G1 cells in study group(44.49?4.33) was lower than that in control group(62.14?26.97).The absorbency value(A) of MDA-MB-435 in study group (0.674?0.221) was significantly higher than that in control group(0.563?0.046).The absorbency valve(A) of MDA-MB-231 in study group (0.674?0.221) was significantly higher than that in control group(0.563?0.046).Conclusion:Exogenous hyaluronidase may promote the proliferation of breast cancer cell lines in vitro.

Epidermal growth factor receptor(EGFR) family plays an important role in the development of gastric cancer. EGFR-targeted therapeutic agents include extracellular monoclonal antibodies and intracellular tyrosine kinase inhibitors. Many new agents such as trastuzumab, cetuximab, panitumumab and lapatinib, have been tested in randomized phase Ⅲ clinical trials. Results from ToGA trial may shed some light on the treatment of advanced gastric cancer.

Tumor progression is often associated with immune suppression or the ability of the tumors to avoid immune surveillance.Immunotherapy improves the ability of the immune system to recognize and clear tumor cells with a little influence on the normal tissues.Immunotherapy is a hot spot in the research of advanced esophageal cancer.Innnunotherapy of esophageal cancer includes immune checkpoint inhibitors,adoptive cellular immunotherapy,tumor vaccines and antibody therapy.At present,a large number of clinical trials are underway to evaluate the role of immunotherapy in esophageal cancer.Checkpoint inhibitors represented by Pembrolizumab and Nivolumab,has achieved initial success in the treatment of advanced esophageal cancer to improve the prognosis and life quality of esophageal cancer patients.In the future,further studies are needed to have a research on the effects of tumor heterogeneity,prediction of therapeutic targets,and immune tolerance.

Objective To study of vascular false as the clinical effect and safety of acromastitis were treated by com -pound anisodine treatment , to provide reference for the treatment of vascular pseudo optic .Methods From June 2013 to June 2015, 132 cases of patients with vascular pseudo optic papilla in our hospital were selected as the observation objects , and were divided into observation group and control group each 66 cases according to the treatment method .The control group was treated with routine drug therapy , and the observation group in the control group on the basis of daily injections of Com -pound Anisodine Hydrobromide Injection .Two groups before and after the treatment of vision changes , and the treatment of safety and efficacy were compared .Results The curative effect:The two groups of patients after treatment were improved , but the observation group was significantly higher than the control group after treatment ;The cure rate and total effective rate of the observation group were 39.51%and 88.89%respectively, which was significantly higher than the control group of 24. 36%and 73.08%, and had better curative effect in observation group .Security aspect:The total incidence of adverse reac-tions in the observation group and the treatment group was 10.61%, significantly less than 24.24% of the control group, higher safety .Conclusion In the treatment of vascular pseudoaneurysms as papillitis drugs , the curative effect of compound anisodine is much better with better security , which can significantly improve the visual acuity of the patients .

Objective To study the chemical constituents in fruits of Catalpa ovata. Methods Isolation and purification were carried out by silica gel, Sephadex LH-20, and active carbon column chromatography etc. Constituents were identified and structurally elucidated by physicochemical properties and spectral analysis. Results Eight compounds were obtained, six of them were determined as catalpol (Ⅰ), catalposide (Ⅱ), ursolic acid (Ⅲ), ?-daucosterol (Ⅳ), nonacosane (Ⅴ), ?-sitosterol (Ⅵ). (Conclusion)(All (~1H-NMR) and (~(13)C-NMR) chemical shifts of the compound) Ⅱ are assigned by UV, IR, ESI-MS, HREI-MS, (~1H-NMR), (~(13)C-NMR), HMQC, and HMBC techniques. Compounds Ⅲ and Ⅴ are isolated from the plant for the first time.

Objective To observe the expression and localization of the islet amyloid polypeptide(IAPP) in the stomach of human fetus. Methods The localization of IAPP immunoreactive(IR) cells in 12 human fetal bodies of stomach from 11th to 20th week of gestation was investigated with immunohistochemical SABC method. Results At 11th week of human fetal age,the IAPP-IR cells had been found in the gastric mucosa.The IAPP-IR cells were dominantly concentrated in the fundic gland.The number of IAPP-IR cells increased gradually,and the immunostain of immunoreactive cells darkened gradually from 14th to 20th week of gestation.As compared with the adjacent sections which were stained by HE,some IAPP-IR cells were co-localization with parietal cells.Conclusion IAPP-IR cells exist in the human fetal body of stomach..

Objective To study the chemical constituents in fruits of Catalpa ovata.Methods Various chromatographic techniques were used to separate and purify the constituents.Structures of the compounds were elucidated by physicochemical properties and spectral analysis (UV, IR, ESI-MS, 1H-NMR , 13 C-NMR , 1H- 1H COSY , HMQC, HMBC, NOESY, and CD).Results A compound was isolated and identified as 2(S)-(3′-hydroxy-5′-methoxy)-benz-3(S)-ethoxycarbonyl-6-trans-ethyl acrylate-8-methoxy-benzofuran.Conclusion This compound is a novel compound named as catalpafurxin.

Objective:To explore the relationship between Jiegu pastes and blood biochemical indices and the expression of cal-catonin gene related peptide( CGRP) in the process of fracture healing. Methods: The tibial fracture model of rats was established, and the rats were randomly divided into five groups:the blank control group, model control group, positive control group, Jiegu paste at low dose group ( L, 1 g·ml-1 , calculated by raw materials) and at high dose group ( H, 2 g·ml-1 , calculated by raw materials) with 60 ones in each. The blank control group and the model control group were given 2 ml saline, the positive control group was given 2 ml concentrated dipsacus bone mixture, and Jiegu paste L group and H group was given 2 ml concentrated solution at low concentra-tion and high concentration, respectively, and all the groups were with the following regimen: ig,qd, for 28 days. The blood samples and callus specimens were obtained on the 7th, 14th, 21st and 28th day after fracture. Blood biochemical indices were detected, and HE staining and immunohistochemical staining were performed. Results: Compared with those in the model control group, the serum calcium and phosphorus ion concentration in Jiegu paste H group significantly increased on the 14th and 21st day, and the serum AKP significantly increased on the 14th and 28th day (P<0. 05). The expression of CGRP in Jiegu paste H group was significantly higher than that in the control group (P<0. 05). There were no significant differences between H group and the positive control group (P>0. 05). Conclusion:Jiegu paste can achieve the purpose of promoting fracture healing by improving the activity of serum AKP, in-creasing the concentration of calcium and phosphorus and regulating the activity of neuropeptide CGRP.
