1.Research Progress on Interleukin-6 Inhibitors in the Treatment of Rheumatoid Arthritis
Herald of Medicine 2017;36(6):646-649
Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by polyarthritis.Numerous agents with varying mechanisms are used in the treatment of RA,but there is no radical cure.Interleukin-6 (IL-6) plays an important role in the pathogenesis of RA.Agents targeting IL-6 such as tocilizumab (TCZ) attracted significant attention as a promising agent in RA treatment.This article reviewed the key efficacy and safety data from clinical trials of TCZ,as well as six candidate IL-6 blockers including sarilumab,ALX-0061,sirukumab,MEDI5117,clazakizumab,and olokizumab,and their future perspectives in the treatment of RA.
2.Influence of baicalin on the expression of receptor activator of nuclear factor-κB ligand and osteoprotegerin in human periodontal ligament cells
Journal of Pharmaceutical Analysis 2009;21(4):256-262
Objective To study the effect of baicalin on the expression of receptor activator of nuclear factor-κB ligand (RANKL) and osteoprotegerin (OPG) in cultured human periodontal ligament (HPDL) cells. Methods Small interfering RNA (siRNA) eukaryotic expression vector targeted transforming growth factor βⅡ receptor (TGF-β RⅡ) was constructed and transfected into T cells. HPDL cells with T cells transfected with siRNA or not were placed in the culture medium that had been added with lipopolysaccharide (LPS) and baicalin. The obtained solution was divided into six groups according to the components (group Ⅰ: HPDL cells+LPS+T cells transfected with siRNA1+baicalin;group Ⅱ: HPDL cells+LPS+T cells transfected with siRNA1; group Ⅲ: HPDL cells+LPS+T cells+baicalin; group Ⅳ: HPDL cells+LPS+T cells; group Ⅴ: HPDL cells+baicalin; group Ⅵ: HPDL cells) and was cultured for 48 hours. RT-PCR was used to observe the effect of baicalin on the expression of OPG-RANKL in HPDL cells. Results The ratio of RANKL/OPG in group Ⅰ was lower than that in group Ⅱ (P<0.01) and higher than that in group Ⅲ (P<0.01); The ratio of RANKL/OPG in gronp Ⅲ was lower than that in group Ⅳ (P<0.01); the ratio of RANKL/ OPG in group Ⅳ was higher than that in group Ⅵ (P<0.01); the ratio of RANKL/OPG in group Ⅴ was lower than TGF-β signaling transduction plays an important role in the effect of baicalin on the RANKL/OPG ratio in HPDL cells.

4.THE CHANGES OF MYOSIN ATPase ACTIVITY AND ITS ISOENZYME DISTRIBUTION IN EARLY STAGE OF CARDIAC HYPERTROPHY FOLLOWING MYOCARDIAL INFARCTION IN RATS
Journal of Xi'an Jiaotong University(Medical Sciences) 1981;0(02):-
To investigate the changes of cardiac myosin ATPase and its isoenzyme in early stage of cardiac hypertrophy following myocardial infarction(MI), we studied myosin ATPase activitzy, isoenyme distriibution and myocardial fiber diameter of uninfarcted ventricu lar sfptum, 9 aed 21 days after operation in MI rats. The results showed that coincident with the increases in myocardial fiber diameter on 9 days after MI, both myosin ATPase activity and V_1 isoenzyme amount were depressed. These changes were more pronounced on 21 after MI. It is suggested that with the development of myocardial hypertrophy in early stage of MI, adaptive changes in myosin ATPase activity and isoenzyme distribution occur.
5.Nursing of patients with Swyer syndrome

6.Simultaneous Determination of Vinyl Chloride and Vinylidene Chloride in Drug Packaging Materials Con-taining Polyvinyl Chloride/Polyvinylidene Chloride by HS-GC
China Pharmacist 2016;19(7):1413-1414,1415
Objective:To develop a method for the simultaneous determination of vinyl chloride and vinylidenechloride in drug packaging materials containing polyvinyl chloride /polyvinylidene chloride by HS-GC.Methods: A Stabilwax (30.0 m ×0.25 mm, 0.25 μm) capillary column and an FID detector were adopted .The headspace equivalent temperature was 80℃for 30 min and the col-umn temperature was 40℃.The inlet temperature was 190℃and the detector temperature was 210℃.N2 was used as the carrier gas . The flow rate was 1.0 ml · min-1 .Results: Vinyl chloride had a good linear relationship within the range of 0.5-2.5 μg ( r =0.996 7), and the average recovery was 90.4%(RSD=0.9%, n=9).Vinylidenechloride had a good linear relationship within the range of 1.0-5.0 μg (r=0.999 0), and the average recovery was 90.0%(RSD=0.6%, n=9).Conclusion: The method is fast and accurate in the simultaneous determination of vinyl chloride and vinylidenechloride in drug packaging materials containing polyvinyl chloride/polyvinylidene chloride .
7.Mammography qualifying diagnosis analysis of atypical solitary breast nodules
Journal of Practical Radiology 2017;33(2):218-220,225
Objective To investigate the qualitative diagnostic features of less than 2 cm atypical solitary breast nodules.Methods 52 patients diagnosed with atypical solitary breast nodules as well as the mammography and clinical characteristics were analyzed retrospectively.Results Among those 52 cases of nodular lesions,there were 23 benign nodules and 29 malignant nodules.Among these 29 malignant cases,26 cases were misdiagnosed as benign lesions,the X-ray of which showed the margin of nodules were mostly smooth,the density relatively homogenic yet with no sign of lobulation.Meanwhile,19 cases were diagnosed as malignant lesions, the X-ray of which showed irregular nodules,uneven density with or without multiple calcification,their margin lobulated,ragged, and ambient structure irregularity.In some case their local skin thickened and subcutaneous axungia were turbid.There were 7 cases unable to make timely diagnosis,the X-ray of which showed more or less regular form,uneven or almost even density,ambient structure barely regular,lack typical features.Conclusion To make accurate diagnosis,it is necessary to understand the characteristics of the pathology X-ray of different lesions,the atypical manifestation,plus comprehensive and detailed analysis,combing ultrasound and clinical palpation,MRI,biopsy and follow-ups when needed.
