1.The study of quantitative evaluation of hypoxia of the patients with pulmonary heart disease
Chinese Journal of Practical Nursing 2011;27(2):62-64
Objective To find a grading method for assisting in evaluating hypoxia degree of patients with pulmonary heart disease non-invasively. Methods To design a quantitative method to score degree of hypoxia of 67 patients with pulmonary heart disease by using acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) as a frame and to make comparative analysis between the grading result and artery blood gas to find the correlation. Results There was a negative correlation between evaluation mark and pH、PaO2、SaO2 and a positive correlation between the evaluation mark and PaCO2, according to statistics. Conclusions Although the grading table of hypoxia evaluation can not substitute blood gas analysis, acting as a non-invasive method to assist in evaluating the hypoxia degree of patients with pulmonary heart disease, it can not only relieve patients' repeated punctuation pain, but also achieve the goal of estimating hypoxia.Consequently the non-invasive method to evaluate hypoxia is of clinical value.

4.Research progress of the new tumor suppressor gene SLC5A8
International Journal of Surgery 2013;40(8):547-550
Current research suggests that SLC5A8 is a new candidate tumor-suppressor gene whose expression is reduced or deficient in human thyroid cancer,esophageal cancer,gastric cancer,colon cancer and acute myeloid leukemia.The gene is in human chromosomes 12q13-23,and encoding proteins that belongs to the members of the family of sodium/glucose transporters.It is sodium-coupled carrier that transfer short chain fatty acid,lactic acid,nicotinic acid and iodide.The exon 1 of GPG island methylation and histone acetylation can make SLC5A8 gene express silenced and promote the occurrence of tumor.of all transporter substrates of SLC5A8 expresses,butyrate,propionate and pyruvate function as histone deacetylase inhibitors and can be mediated apoptosis of many kinds of tumor cells,which may be the mechanism of inhibiting tumor.
5.Tumor necrosis factor-α and cerebral ischemia-reperfusion injury
International Journal of Cerebrovascular Diseases 2009;17(1):60-62
As an important inflammatory cytokine, tumor necrosis factor-α (TNT-α) plays an important role in the process of cerebral ischemia-reperfusion. The discussion of the dynamic changes, the mechanism of neurotoxicity and antagonizing the therapeutic effect of TNF-α in the process of cerebral ischemia-reperfusion injury will provide theoretical basis for the treatment of cerebrovascular diseases.
6.Construction of risk early-warning system for medical quality
Chinese Journal of Medical Science Research Management 2010;23(2):93-96
Up to present,the research of the early-warning system for the risk of the medical quality has been carried out both at home and abroad.The majority of these researches aimed at providing theoretical guidance for the scientific decision-making of local health departments.In order to construct quality of medical care evaluation indicators system.On the bases of intelligence research,drawing on a series of internationally recognized quality of medical care evaluation system.The majority of these researches aimed at providing theoretical guidance for the scientific decision-making of local health departments.However,the hospital-related research is very limited.Therefore,hospitals were selected as objects in this study.33 experts from 6 three"A" hospitals were selected.And by using a series of internationally recognized quality health care system as a source of reference and focusing on process control and standardizing of management,the early-warning system for the risk of the medical quality has been constructed based on the combination of theory and practice.At the same time,Delphi method was used to verify the results repeatedly to form a set of early-warning system for the risk of the medical quality which is objective,scientific and approved by experts.

8.Tissue-engineered scaffold preparation using three-dimensional printing technology:a retrospective study on bone repair
Chinese Journal of Tissue Engineering Research 2017;21(10):1611-1616
BACKGROUND: The tissue-engineered scaffold, as a substitute of autogenous bone graft, plays an important role in bone repair. In the meanwhile, three-dimensional (3D) printing technology has obtained more attention because of its accurate adjustment.OBJECTIVE: To review the in vitro or in vivo studies on the 3D-printed scaffolds applied in bone repair, thus providing basis for clinical research.METHODS: The first author searched the PubMed database using the English keywords of tissue engineering, bone,three-dimensional printing, scaffold for pertinent articles addressing 3D-printed tissue-engineered scaffolds.RESULTS AND CONCLUSION: There are plenty of studies on 3D-printed tissue-engineered scaffolds, and recent research focuses on the material selection and surface modification. The appropriate porosity is vital, and with the development of manufacturing technology, each property of the scaffold is improved, and composite materials prevail gradually. All above improvements enhance the mechanical property and promote cell adhesion and proliferation.Furthermore, the surface modification promotes the implant-bone interaction. In vivo and in vitro research both indicate that composite materials with the surface coating of bone induction can improve the scaffold performance and osteogenesis.
9.Proton and heavy ion radiotherapy: the context and challenges
Chinese Journal of Radiological Medicine and Protection 2016;36(8):616-620
Protons and heavy ion radiation therapy have proven highly effective against a wide range of cancers and in recent decades there have been rapid advances.Due to the physical characteristics of the Bragg-peak and superior biological properties,proton and heavy ion radiation is able to focus its energy on the tumor while minimizing exposure to surrounding normal tissues and organs,which is expected help enhance the tumor dose and reduce normal tissue damage.In recent years,many studies have explored the efficacy and safety of proton and heavy ion radiotherapy on various malignancies,such as head and neck cancer,lung cancer,esophageal cancer,and liver cancer.The results of these studies enable a better understanding of the characteristics and advantages of proton and heavy ion therapy.

Objective To investigate the relation of DNA content and SPF to the clinicopathological characteristic in lung cancer.Methods Fresh specimens taken from 56 patients with lung cancer and 36 patients with non-malignant pulmonary lesions were measured for DNA index(DI),S-phase fraction(SPF) by using FACSCalibur 4200 flow cytometry.Results ① DNA index(DI) of lung cancer was 1.18?0.33,0.99?0.07 in lung cancer and non-malignant groups,respectively.The percentage of heteroploid was 78.6% in lung cancer,(5.6%) in non-malignant.DI and the positive rate of heteroploid were significantly higher in lung cancer groups than that in non-malignant group(P0.05);③ It was demonstrated that SPF was significant higher in lung cancer groups than that in non-malignant group. The SPF of heteroploid tumors was higher than that of diploid tumors(P
