Objective To investigate the application effect of indwelling needle puncture in the axillary vein of newborn infants.Methods From September 2015 to February 2016,the venous indwelling needle puncture was given for neonatal transfusion 180 cases,including 90 cases of the axillary vein indwelling needle infusion in the experimental group,and 90 cases of puncture of extremity vein infusion in the control group.The application effect of the 2 groups was compared.Results There were significant differences in terms of indwelling needle shedding,phlebitis,drug extravasation,lien time between the experimental group and the control group (P < 0.05) Conclusions During neonatal indwelling needle puncture infusion process,the axillary vein indwelling needle infusion can prevent the indwelling needle shedding,decrease the incidence of phlebitis and reduce the incidence of drug extravasation,and can prolong the indwelling time.Puncture in the simple operation easy,is easy to learn and no need for special facilities and equipment,only conventional intravenous infusion required material,plus 24g indwelling needle,aseptic transparent dressing,paper tape,economical and practical,suitable for application in neonatal ward.
2.The Application of the Puncture Method of Indwelling Needle by Single Hand in Puncture Technique of Pediatrics
Journal of Kunming Medical University 2016;37(5):148-150
Objective To investigate the application effect of the puncture method of indwelling needle by single hand in clinical attendance of pediatrics. Methods From March 2015 to September 2015,578 patients in our pediatrics were randomly and equally divided into two groups. The experiment group were treated with the puncture method of indwelling needle by single hand and the control group received traditional puncturing method. Results There were statistical significances in the success rate of first puncture,degree of comfort,sense of pain,dropping of the indwelling needle,phlebitis,exosmosis of drugs and indwelling time of patients between the two groups(P< 0.05). Conclusion In the process of using indwelling needle in pediatrics,the application of the puncture method of indwelling needle by single hand could improve the success rate of first puncture of venous retention needle,enhance the comfort degree of neonates,relieve the sense of pain,reduce the dropping of the indwelling needle,incidence of phlebitis and exosmosis of drugs,and prolong the indwelling time. The operation of this puncture is simple and easy to do and to learn,without any special equipment. In the venous puncture,the only necessities are 24G retention needle,3M indwelling needle and adhesive tape. Obviously,it is economical and practical,and is suitable for application in clinic.
3.Determination of Diprophylline in Diprophylline Tablets by HPLC
China Pharmacy 2001;0(07):-
OBJECTIVE: To establish an HPLC method for the determination of diprophylline in diprophylline tablets. METHODS: The analytical column was C18 and the mobile phase consisted of methanol-water (30∶ 70) at a flow rate of 1.0 mL?min-1. The detection wavelength was 273 nm and the sample size was 20 ?L. RESULTS: The linear range of diprophylline was 8.1~81 ?g?mL-1 (r=0.999 8) with an average recovery rate of 100.01% (RSD=0.21%). CONCLUSION: The method is simple, accurate and precise, and it can be used for the quality control of diprophylline tablets.

Chinese Journal of Medical Education Research 2012;11(8):840-843
Language,as a cartier of specified social culture,is closely and complementarily associated with it.Considering the especial education targets of medical universities and colleges,the present curriculum and the trend of international communication,College English is obliged to focus on humanistic value and necessarily plays its constructive role in heightening students' humanistic quality.
5.Information of clinical studies on the effect of collagen peptides on joint pain in athletes
Chinese Journal of Clinical Nutrition 2012;20(2):128-129
Recent clinical studies have shown that collagen peptides may reduce joint pain and the dependence on analgesics,and enhance sport ability in athletes.Therefore,collagen peptides may be a safe nutrient supplement for prevention and mitigation of joint pain in athletes.
6.Research and treatment of invasive pituitary adenomas: current status and future expectation
Academic Journal of Second Military Medical University 2000;0(08):-
Invasive pituitary adenoma is a common pituitary adenoma invading nearby structures such as the sphenoidal sinus, ethmoidal sinus,upper clivus,sellar floor dura and bone. With the development of diagnosis neuroradiology, endocrinology,pathology and microsurgery,dramatic progress has been made on the pathogenesis, pre operative diagnosis and therapy of invasive pituitary adenoma.The development of pathology,molecular biological and medication and surgical therapy of invasive pituitary adenoma in the past few years is discussed in this paper.
7.Study on immunogenicity of a novel bionic scaffold of nucleus pulposus tissue engineering
Journal of Third Military Medical University 2003;0(09):-
Objective To explore the immunogenicity of a novel bionic scaffold of nucleus pulposus tissue engineering. Methods The biocompatibility of a subcutaneously implanted scaffold of nucleus pulposus tissue engineering was studied in SD rats by analyzing tissue reactions up to 3 months using histological and ultrastructural methods. The expression of IFN-?, IL-2, IL-4 and IL-10 mRNA was measured by RT-PCR, and the levels of serum antibodies to porcine type Ⅱ collagen were measured by ELISA. Results There was less inflammatory reaction in rats induced by subcutaneously implanted scaffold. By degrees, a granulation tissue had developed within the implant, which had disappeared by 3 months. The expression of IFN-?, IL-2 mRNA by RT-PCR was of no changes. But the expression of IL-4 and IL-10 mRNA increased, which meant the implant induced Th cell into Th2 cell and the induction inhibited the inflammatory reaction. No antibodies to porcine type Ⅱ collagen were found in the sera of implanted rats. Conclusion There was less immunogenicity in rats induced by implanted scaffold of nucleus pulposus tissue engineering.
9.THE AFFERENT CONNECTIONS OF THE NUCLEUS TEGMENTI DORSALIS IN THE ALBINO RAT
Acta Anatomica Sinica 1953;0(01):-
Afferent connections to the nucleus tegmenti dorsalis were studied by means of retrograde axonal transport method of horseradish peroxidase (HRP). HRP was depositted stereotaxically via three approaches: vertical, oblique through the cerebellum or oblique through the cerebrum. The serial sections were treated by 3,3'-diamino-benzidine, benzidine dihydrochloride, diaminobenzidine-cobalt dichloride or tetrame-thylbenzidine respectively.Labeled neurons were observed in following nuclei: nucleus lateralis habenulae,nucleus interpeduncularis, nucleus mammillaris lateralis, nucleus posterior hypothalami, nucleus lateralis hypothalami, substantia grisea centralis mesencephali, nucleus dorsalis raphes, nucleus tractus solitarii, nucleus prepositus hypoglossi, nucleus parafascicularis and nucleus of Darkschewitsch.Then HRP was introduced into nucleus parafascicularis or nucleus prepositus hypoglossi, labeled terminals were also observed within the nucleus tegmenti dorselis.
