2.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.

4.Discussion of Daily Drug Management Mode of Locomotive Logistics Unit and Design of Management Module Function
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.
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.
7.The application of inverted internal limiting membrane flap technique in macular hole
Chinese Journal of Ocular Fundus Diseases 2016;32(5):561-563
Vitrectomy combined with internal limiting membrane (ILM) peeling and vitreous tamponade is a conventional method for treating macular hole (MH),but the visual acuity and MH closure rate remains to be further improved.After removal of posterior vitreous cortex,the ILM is grasped with an ILM forceps and peeled off in a circular fashion for approximately 1 disc diameters around the MH.During the circumferential peeling,the ILM is not removed completely from the retina but is left attached to the edges of the MH.The ILM was then massaged gently over the MH from all sides until the ILM became inverted and then peel all other ILM within vascular arcades.Inverted ILM flap technique is one of the important improvement methods in MH vitrectomy,especially for MH with large diameter and unhealed MH after ILM peeling.Compared with conventional vitrectomy combined with ILM peeling,inverted ILM flap technique can enhance MH closure and improve visual acuity.Due to lack of large sample observation in clinical trials of inverted ILM flap technique,we still need more cases and longer follow-up of this technology to more accurately evaluate the effectiveness and safety of this technique.
8.Effect of Plantago depressa Willd. Extract on Chronic Nonbacterial Prostatitis in Rats
Herald of Medicine 2016;35(6):592-596
Objective To study the effect and mechanism of Plantago depressa Willd. extract on rats with chronic nonbacterial prostatitis. Methods Sixty rats were divided into six groups randomly: normal control group, model control group, cernilton group, high-, medium- and low- dose Plantago depressa Willd. extract group, ten rats in each group. Chronic nonbacterial prostatitis rat model was established in the animals except of normal control group. Rats in the cernilton group were administrated with cernilton solution( 100 mg . kg-1 ) . High, middle and low dose Plantago depressa Willd. extract groups were given 150, 300 and 600 mg . kg-1 of Plantago depressa Willd. extract, respectively. The rats in the normal control and model control group were treated with the same volume of purified water.The administration was performed once every day, and lasted for three weeks.Effects of Plantago depressa Willd.extract on prostate index (PI), prostate specific antigen (PSA), tumor necrosis factorα ( TNF-α) , interleukin-1β ( IL-1β) , cycloxygenase 2 ( COX-2) , prostaglandin E2( PEG2 ) , transforming growth factor-β1( TGF-β1 ) , and connective tissue growth factor ( CTGF ) levels and pathological changes of prostate tissue in rats were observed. Results PI and PSA levels of the normal control group were(0.8±0.3)mg.g-1 and(106.5±10.6)pg.mL-1, respectively;those of the model control group were(2.2±0.2)mg.g-1 and(319.4±23.4)pg.mL-1 respectively;Those of the cernilton group were(1.6±0.3)mg.g-1 and(179.5±13.7)pg.mL-1 respectively;Those of the low-, medium- and high- dose Plantago depressa Willd.extract groups were(1.8±0.4),(1.3±0.3),(0.8±0.3)mg.g-1 and(263.4±28.6),(178.5±21.5), (143.5±12.9)pg.mL-1, respectively.Compared with the model control group, PI and PSA were significantly decreased(P<0.01) , TNF-α, IL-1β, COX-2, PEG2 , TGF-β1 and CTGF levels in the prostate tissues were decreased ( P<0. 01 ) , and inflammatory cell infiltration and fibrosis of prostate tissue was significantly alleviated in the model control group. Conclusion This study confirms Plantago depressa Willd.extract exerts effective therapeutical effect on chronic nonbacterial prostatitis in rats.
