1.Soft regulation of inflammatory immune responses
Chinese Pharmacological Bulletin 2016;32(3):297-303
Inflammation reaction and immune response are in-separable in the levels of system, tissue, cell and molecule. In-flammatory immune responses ( IIR) is proposed in this paper, which is defined a moderate or abnormal system responses of in-flammatory immune related cells in responding to the internal and external environment changes of body. It is described briefly that the research progresses of inflammatory immune cells ( e. g. , macrophages, dendritic cells, T cells and B cells, etc. ) and non-inflammatory immune cells ( e. g. , glial cells, endothe-lial cells, epithelial cells, fibroblasts, synovial cells and liver cells, etc. ) , and cytokines/receptor signal transduction in-volved in IIR. Moreover, the existing problems about regulating IIR drugs clinically are summarized. It is firstly put forward that soft regulation of inflammatory immune responses ( SRIIR) is a new direction of discovery and development of new drugs for the treatment of IIR related diseases.
2.The antisaccade in children with autistic spectrum disorders
International Journal of Pediatrics 2010;37(5):521-523
Recent studies demonstrate that autistic spectrum disprders children have deficits in executive functiony, particularly the function referred response inhibition. The antisaccade task provides a new tool for direct evaluation of inhibitory function and a new way to explore the character of response inhibition in children with cognitive impairment. Researchers have used the technologies of eye movement to reveal the ability of oculomotor inhibition in children with autistic spectrum disprders, which is poorer than that of normal children.

5.Studies on Volatile Constituents and Their Anti-tumor Activities from the Peel and Shell of Podocarpus nagi Fruits
Herald of Medicine 2015;(5):609-612
Objective To compare the volatile constituents and anti-tumor activity from the peel and shell parts of Podocarpus nageia fruits. Methods Steam distillation was used for extracting volatile oil from the peel and nutshell of Podocarpus nageia, and gas chromatography-mass spectrometry was exploited to compare the chemical compositions. Their anti-tumor activities were studied by the MTT assay. Results The yield of volatile oil from nageia peel was 0. 23%. 21 kinds of composition were isolated and 18 kinds were identified, the main composition was caryophyllene, accounting for 72. 44% contents of the total volatile oil. The volatile oil from nageia nutshell was 0. 15%. 15 kinds of composition were isolated and 13 species were identified from the nutshell. 4 compositions were found in both two parts. The volatile oil from both of nageia peel and nutshell inhibitted nasopharyngeal carcinoma cells proliferation in vitro, and the IC50 were 54. 58 and 114. 83 μg·mL-1 , which indicated that the volatile oil from the peel showed stronger inhibitory activity. Conclusion The main components in the volatile oil from nageia fruit are alkenes, alcohols and terpenes. The volatile oil extracted from peel shows comparable stronger anti-tumor activity.

8.Multimodal intervention measures to improve efficacy of hand hygiene compliance rate
Chinese Journal of Infection Control 2015;(7):455-458
Objective To evaluate the feasible hand hygiene intervention methods to improve health care workers’ (HCWs)hand hygiene compliance,and reduce healthcare-associated infection(HAI)rate.Methods The surgical department in a hospital was selected as intervention department,intervention department was conducted baseline investigation in January-February 2013,multimodel intervention measures were conducted between March 2013 and April 2014,post-intervention survey was performed by the same method as baseline survey in May-June 2014,hand hygiene of HCWs as well as occurrence of HAI between before and after intervention was compared respectively. Results After intervention,HCWs’hand hygiene compliance before and after patient contact both enhanced signifi-cantly;HCWs’hand hygiene compliance rate increased from 53.32% before intervention to 69.27% after interven-tion,the difference was significant(χ2= 26.19,P<0.001 ). HCWs’hand hygiene modes before patient contact:liquid soap plus running water before intervention(67.02% ),alcohol-based hand rub after intervention (61 .08% );HCWs’hand hygiene modes after patient contact :both liquid soap plus running water before and after intervention (86.40% and 70.41% respectively). Before intervention,hand dry method of HCWs before and after patient con-tact was by wiping with uniforms,after intervention was by wiping with paper towel. HAI in intervention depart-ment decreased from 3.08% before intervention to 2.00% after intervention,the difference was significant(χ2=7.76,P= 0.005).Conclusion Multimodel intervention measures in intervention department can effectively improve HCWs’hand hygiene compliance rate.

Clinical Medicine of China 2015;31(5):394-397
Objective To investigate the effect of renal anemia variability on the progression of renal function in patients with chronic kidney disease and hemoglobin variability on the incidence of cardiovascularevents,mortality and re-hospitalization rate.Methods one hundred and twenty-three patients with chronickidney disease with stage Ⅲ-Ⅴ were enrolled in this study.The information of hemoglobin variability,creatinineclearance rate (Ccr),renal function,the incidence of cardiovascular events,mortality and rehospitalization rate,the incidence of cardiovascular events,mortality and rehospitalization rate were recorded and analyzed.ResultsThe change of hemoglobin level was (20.6 ± 10.7) g/L and Ccr change level was (16.3 ± 4.1) ml/min inpatients,and the pearson correlation coefficient was 0.82.Multiple covariance analysis showed that Ccr increaselevel was higher in CKD Ⅲ-Ⅴ period patients with hemoglobin fluctuations than that of hemoglobin stabilitypatients after adjusting smoking history,blood pressure,24 h urinary protein quantitative factors (F =7.6,9.1,4.3;P<0.05).The incidence of cardiovascular events in patients,mortality,rehospitalization rate of hemoglobinwave group were higher than those of hemoglobin stabilizing group(x2 =26.9,5.1,10.6,P<0.05 or P<0.01).Conclusion The fluctuation of hemoglobin is able to aggravate quickly of renal function development,increasethe incidence,mortality and rehospitalization rate of cardiovascular events.
10.Radiofrequency ablation for the treatment of recurrent hepatocellular carcinoma:analysis of the therapeutic results and prognostic factors
Journal of Interventional Radiology 2015;(10):923-927
Based on both domestic and abroad research results concerning the local therapeutic efficacy, influence factors, survival time and prognosis of radiofrequency ablation (RFA) in treating recurrent hepatocellular carcinoma (HCC), this paper aims to make a review of medical literatures about RFA treatment of recurrent HCC that were published in Chinese and in English during the period from 2005 to 2014, and to analyze the related factors that may influence the local therapeutic efficacy and survival rate. The results indicate that the recurrent tumor size, tumor number, recurrence interval, serum alpha fetoprotein (AFP) level, serum prothrombin, etc. are important factors that will affect the therapeutic efficacy of recurrent HCC. At the same time, the results point out that the study of imaging predictors can help suggest the different recurrent types, which is very useful in making individualized follow-up strategy and in monitoring tumor recurrence. Local treatment, with RFA being the main method, together with comprehensive therapies, including other new technologies and new drugs, will improve the current clinical situation in treating recurrent HCC.
