Chinese Health Economics 2014;(4):59-61
Objective: To analyze the efficiency and differences of China Community Health Service, to analyze the shares of eastern-middle-western regional differences and the difference within each region in the total efficiency difference. Methods: The super efficiency DEA model and decomposition of Gini coefficient by Subgroups are used to analyze the provincial data in China from 2008 to 2011. Results: The eastern-central-western regional difference is the major cause of the efficiency differences in China Community Health Service. In the meantime, the shares of the difference within each region in the total efficiency difference are also non-negligible. Conclusion: To narrow the efficiency differences among eastern, central and western areas; improve the inter-regional flow of community health service resources; improve the support and supervision on the backward regions; make regional policies to coordinate the internal resources of community health services and strengthen the assessment mechanism using efficiency as the indicator.
2.Thrombosis and prevention after transcatheter occlusion of atrial septal defect
International Journal of Pediatrics 2012;39(2):122-124
Transcatheter closure as an alternative to medical surgery has become a preferred therapeutic method to atrial septal defect (ASD).However,thrombopoiesis after occluder implantation has been reported comprehensively and causes a series of serious complications such as cerebral embolism、myocardial infarction,pulmonary embolism and so on.Reasons of device thrombopoiesis are closely associated with atrial fibrillation,persistent atrial septal aneurysm,occluder type,activated coagulation system and occluder endothelialization process.This paper summarizes correlation factors of occluder thrombopoiesis and current related prevention proposal after transcatheter closure of ASD,and provides theoretical and experimental foundation for prevenition of device thrombopoiesis after occluder implantation of ASD.
3.Neo-adjuvant endocrine therapy in breast cancer
Cancer Research and Clinic 2011;23(2):139-141
Nco-adjuvant endocrine therapy has provided opened new alternatives for locally advanced breast cancer, especially for patient groups such as the elderly, those who are not suited for chemotherapy, and those whose response may not be optimal. The latest generation of endocrine therapy for breast cancer,aromatase inhibitors, has proved superior to tamoxifen in terms of toxicity and efficacy in the adjuvant setting.Compared with neo-adjuvant chemotherapy, the appropriate patients to receive nco-adjuvant endocrine therapy can achieve similar short-term benefit. However, because of fewer long-term follow up results, the overall prognosis is not clear.

6.Progress of molecular biology and treatment for triple negative breast cancer
Journal of International Oncology 2016;43(7):526-528
Triple negative breast cancer (TNBC)is difficult to benefit from endocrine therapy or tras-tuzumab targeted drug therapy.Biological overexpression of breast cancer susceptibility gene 1,p53 gene,vas-cular endothelial growth factor and microRNA suggests that TNBC is easy to metastasis and recurrence and has a poor prognosis.Exploring the molecular subtypes of TNBC,setting out the treatment plan for subtypes and finding the corresponding monoclonal antibody targets are the research direction of TNBC in the future.
7.Inhibition of Celastrus orbiculatus Extracts on VEGF Expression in Hepatoma Cells of Mice
Chinese Herbal Medicines 2010;2(1):72-76
Objective To discuss the antitumor mechanism preliminarily by observing effects of Celastrus orbiculatus extracts (COE) on vascular endothelial growth factor (VEGF) mRNA and protein expression in hepatoma (Hepal-6) cells of mice.Methods Hepa1-6 cells were treated with COE at different nontoxic concentration (0, 10, 20, 40, 80, and 160 μg/mL) for 16 h. The mRNA and protein expressions of VEGF were detected by reverse transcription-PCR and Western Blotting,respectively. Results COE significantly inhibited VEGF expression at both mRNA and protein levels in a dose-dependent manner. Conclusion COE can inhibit VEGF expression in Hepa1-6 cells, therefore suggest that VEGF could be chosen as an therapeutic target for COE in the context of cancer chemoprevention and anticancer therapy.
