1.Advances in research on the early and late effect of delayed umbilical cord clamping on neonatal
International Journal of Pediatrics 2015;42(1):8-10,17
Neonatal is separated from the maternal by clamping the umbilical cord after delivery.And traditionally,the clinical practice is clamping the umbilical cord immediately after delivery.With the futher study of optimal timing of umbilical cord clamping,the effect of delayed umbilical cord clamping attracts more and more attention.This paper discussed about the subject of the early and late effect of delayed umbilical cord clamping on neonatal.We found that a briefly delay in clamping the umbilical cord increased the placental transfusion and blood volume,decreased the prevalence of anemia,promoted the stability of circulation and internal environment,without adversely affecting health of neonatal.

3. Effect of acitretin on the T helper cells of psoriasis vulgaris
Academic Journal of Xi'an Jiaotong University 2010;22(3):198-202
Objective: To investigate the effects of acitretin on T helper cell (Th) 1/Th2 balance and Th17 cells in psoriasis vulgaris (PV) patients. Methods: A total of 13 men and 17 women with PV were investigated. 10 mg of acitretin was administered twice a day for 8 weeks for intervention therapy. Serum levels of interferon-gamma (IFN-γ), interleukin (ID-4 and IL-17 were measured by enzyme-linked immunosorbent assay. T, Th1, Th2 and Th17 cells in skin biopsies were counted with double-labeled immunofluorescence. Psoriasis Area and Severity Index (PASI) score was calculated before and 8 weeks after treatment. Results: Before treatment PV patients had higher serum levels of IFN-γ and IL-17, and increased T, Th1 and Th17 cells in skin biopsies. After treatment, both serum levels of IFN-γ and IL-17, and T, Th1 and Th17 cells infiltrating in PV skin decreased significantly. Th1/Th2 balance was restored to normal. However, their IL-4 and Th2 cells showed no significant change throughout the therapy. Conclusion: Acitretin exerts influence on dermal Th1/Th2 balance and Th17 cell infiltration, so does it on production of systematic inflammatory cytokines IFN-γ and IL-17 in PV patients. However, Th2 cells and its derivative cytokine - IL-4 are not affected.

5.Comparative studies by different dyeing methods on antiserum preparation against hemorrhagins from Agkistrodon acutus venom
Chinese Journal of Immunology 2016;32(12):1793-1796
Objective:In order to look for a good method for preparation of hemorrhagin antiserum. Methods: Three kinds of hemorrhagins including AaH Ⅰ, AaH Ⅱ, and AaH Ⅳ were purified from Agkistrodon acutus venom according to predecessors's methods and crude AaH Ⅰ, AaH Ⅱ and AaH Ⅳ were obtained. Preparation electrophoresis was used to purify AaH Ⅰ,AaH Ⅱand AaH Ⅳ further. As for an hemorrhagin, six different dyeing methods were used to dye PAGE gel and the gel contained hemorrhagin was obtained respectively. The ground gel contained hemorrhagin was used to immune mice and its antiserum was obtained. Antiserums quality was tested through ELISA test and neutralization of the hemorrhagic activities of corresponding hemorrhagin. Results:Effective IgG concentration in different antiserum was different and effective IgG made through non toxic type protein fast stain reagent kit was higher than others. Conclusion:Non toxic type protein fast stain reagent kit is the best dyeing method among the six dyeing methods.
6.Determination of Four Flavonoids in Shenyan Siwei Granules by Quantitative Analysis of Multi-components with Single Marker
Herald of Medicine 2017;36(1):65-69
Objective To establish an HPLC method to measure four flavonoids ( baicalin, wogonoside,baicalein and wogonin) in shenyan siwei granules by quantitative analysis of multi-components with single marker ( QAMS ) . Methods Agilent ZORBAX SB-C18 column(4. 6 mm × 250 mm,5 μm) was used. The mobile phase was composed with methanol and 0. 4% phosphoric acid solutionat at 1. 0 mL·min-1 flow rate with gradient elution. The detection wavelength was 278 nm. Baicalin was used as the internal reference substance. The relative correction factors ( RCF) between the baicalin and the other three flavonoids were established to detect the quantitation of baicalin and calculate the quantitation of the other three constituents. The external standard method was used for quantitating the four constituents, and the method was evaluated by comparing to the quantitative results between external standard method and QAMS method. Results The results of QAMS method had no significant difference with those of external standard method. Conclusion It is feasible and accurate to control the quality of shenyan siwei granules with QAMS.

Chinese Medical Equipment Journal 2003;0(11):-
Objective To explore the daily management mode of hygienic materials of locomotive logistics unit. Methods Through the method of building deposit area and buffer area in regular depot, hygienic materials with validity regulation such as drugs could be included in hospital regular inventory manage ment; the hygienic materials were dynamically replaced according to the hospital's daily cost. Results Under the condition of ensuring the adequateness of hygienic materials, the method was able to meet the validity requirement and avoid wasting as well. Conclusion Hospitals have favorable condition and professional management in reserving different types of hygienic materials. As it costs time to assemble materials, this management mode is more suitable for the management of hygienic materials of locomotive logistics unit.

Carcinogenesis is found in 25 % patients.
10.Review of Study on TCM Intervention in Different Signal Transduction Pathways in ;Pulmonary Fibrosis in China
Chinese Journal of Information on Traditional Chinese Medicine 2017;24(2):127-131
The etiology of pulmonary fibrosis is complex. The occurance and development of this disease involve many cell signal transduction pathways, including MAPK signaling pathway, JAK-STAT signaling pathway, Smad signaling pathway, PI3K-Akt signaling pathway, NF-κB signaling pathway and so on. Numbers of experiments have shown that intervention in signal transduction pathways with TCM can delay the progression of fibrosis, which provides good therapeutic methods for this disease. This article reviewed study on TCM intervention in different signal transduction pathways in the pulmonary fibrosis in China.
