1.MEASUREMENT OF LACTOFERRIN IN HUMAN MILK AND NEONATAL FAECES AND EXPLORATION OF RELATION BETWEEN THEM
Acta Nutrimenta Sinica 1956;0(03):-
The concentrations of lactoferrin (LF) in colostrum during the first 8 days and mature milk during the first 4 months of postpartum were determined by electroimmunodiffusion. Meanwile a sensitive enzyme linked imm-unosorbent assay for measurements of LF in neonatal faeces were established. The results showed that human milk, especially colostrum, was rich in LF. The colostrum contained 6.88 ? 3.10mg/ml (M?SD) aad mature milk 3.18 ? 0.37mg/ml LF. LF in human milk was the highest during the first 3 days of lactation with a decline in concentration as lactation proceeds although a wide variation in concentration was noted among different individuals.LF in neonatal faeces showed significant difference in different feeding manners. LF level in the breast-fed infants was 19 times higher than that in the bottle-fed infants. The LF percentage detected in the former was 100% and the latter only 60%. The dynamic variations of LF in faeces of breast-fed infants during the first day of life were found to be relative to LF level in mother'milk.These data demonstrated the influence of high LF level in mother'milk on the concentrations of LF in breast-fed infants' intestine.Furthermore a few amounts of LF was found in meconium and its percentage detected was 35%. This suggested that the production of endogenous LF began from foetus period, but was limited during the first day of life. LF ingested by the breast-fed infants were not completely destroyed and thus may supplement the insufficiency of the endogenous LF in the newborn infants' intestinal tract.
2.RAM-HPLC vs.FPIA for Determination of Plasma Concentration of Carbamazepine
China Pharmacy 2007;0(29):-
OBJECTIVE:To develop a RAM(Restricted-access media)-HPLC for the determination of plasma concentration of carbamazepine,and to compare the determination results with those determined by FPIA method. METHODS: The plasma samples were centrifugalized,then the venous plasma samples were determined by FPIA and RAM-HPLC,respectively,while the fingertip plasma sample was determined by RAM-HPLC alone. The chromatographic column was Hisep shielded hydrophobic phase analytical column,and the mobile phase consisted of ammonium acetate buffer-acetonitrile (88∶12) at a flow rate of 1.5 mL?min-1. The detective wavelength was set at 280 nm;the sample size was 20 ?L and the column temperature was kept at room temperature. RESULTS: A good correlation was noted between the carbamazepine concentration in venous plasma sample determined by FPIA and carbamazepine concentrations in either venous or fingertip plasma determined by RAM-HPLC,with the correlation coefficients being 0.989 and 0.995,respectively,but the differences were significant(P0.05). CONCLUSION: Both RAM-HPLC and FPIA are applicable for the determination of carbamazepine concentration,but FPIA is more suitable for routine monitoring while RAM-HPLC is more suitable for the related research and monitoring of specific cases. Both methods shows good reproducibility and in which the samples don't have to be pretreated.

5.Impact of past Toxoplasma gondii infection on the fetus during pregnancy
Chinese Journal of Schistosomiasis Control 2010;22(2):187-188
Objective To discuss the activity of Toxoplasma gondii and its impact on fetus during pregnancy.Methods Sixty -eight pregnant women whose IgG was positive and IgM was negative for anti - Toxoplasma gondii antibodies were chosen.Their serum and umbilical blood were tested for IgG,IgM,CAg (by ELISA) and DNA (by PCR) of Toxoplasma gondii.The infections of placental samples were tested by the direct smear,homogenate smear and PCR.Results There were 28 positive cases of Toxoplasma gondii IgG antibodies in cord blood,and the vertical transmission rate of IgG in placenta was 41.2%.There were 6 positive cases of Toxoplasma gondii DNA in cord blood,and the incidence of intrauterine infection was 8.8%.There were 9 positive cases of Toxoplasma gondii DNA in placental tissues,and the incidence of intrauterine infection was 13.2%.Conclusions Past Toxoplasma gondii infection during pregnancy may lead to vertical transmission between the mother and infant.
6.Chinese and Modern Medicine Progress in the Mechanism Study of Restenosis after Percutaneous Coronary Intervention
World Science and Technology-Modernization of Traditional Chinese Medicine 2013;(5):1061-1066
In recent years , along with the continuous accumulation of clinical experiences and the improvement of surgical devices, the percutaneous coronary intervention (PCI) has become a perfect treatment method and been widely used in the clinic . Hence , the coronary heart disease ( CHD ) patients have received better treat-ment results. However, the in-stent restenosis is still a big problem after PCI. The combination of Chinese and modern medicine in the prevention of restenosis has become a focused hotspot . In order to further under-stand this issue , this article discussed the Chinese and modern medicine mechanism in order to provide more thoughts for clinical practice .
7.Changes of L-selectin expression on peripheral blood polymorphonuclear leukocytes and their significance in rats with acute lung injury
Chinese Journal of Pathophysiology 1986;0(03):-
AIM: To explore the changes of L-selectin expression on peripheral blood polymorphonuclear leukocytes (PMNs) and their significance in rats with acute lung injury (ALI). METHODS: ALI model in rat was established by intravonous injection of E. coli endotoxin (ET). The expression of L-selectin on peripheral blood PMNs was measured by immunofluorescence and flow cytometry.RESULTS: The contribution of L-selectin fluorescence signal was on the surface of PMNs membrane. The expression of L-selectin on poeripheral blood PMN was significantly lower at 5 min after injection of ET and the lowest during 15 min to 30 min, then gradually increased, but the expression of L-selectin on PMN was lower at 60 min after injection of ET than that of control animal.CONCLUSION: In physiological state, L-selectin were expressed on the surface of PMN membrane. The protein expression of L-selectin on PMNs reduced rapidly after injection of ET and the lowest at 15 min, then gradually increased. L-selectin may play a role in the development of ALI.
8.Application of MRI in the diagnosis of fetal malformations
International Journal of Pediatrics 2010;37(1):92-95
Magnetic resonance imaging(MRI) has multi-faceted advantages due to its non-ionization radiation, excellent tissue contrast, high spatial resolution and multi-dimensional imaging technique. It can clearly observe the pathological changes of deseases, and judge for the prognosis. With the development of MRI, MRI has become increasingly popular in the diagnosis of fetal malformation. In this paper, it is described the value of MRd in the diagnosis, management and prognosis of fetuses malformations, via the central nervous system, circulatory system, respiratory system, digestive system, genitourinary system, musculoskeletal system, endocrine system, and so on.

Combined with the routine work of preventing and treating diseases, the construction of a clean and honest administration in stomatological hospital would be beneficial to raise the administrative staff's awareness of the constructive characteristics of a clean and honest administration in their work belief and methods to enhance the work initiative and effectiveness.
10.Safe margin of breast conserving surgery for breast cancer
Journal of International Oncology 2016;43(6):458-461
Breast conserving surgery has become the first choice for the treatment of early breast cancer.However,the safety margin is still one of the important issues for surgeons in the implementation of breast conserving surgery.Because variety of clinical factors have some effects on the safety margin,at present,no consensus on safe margin of breast conserving surgery is reached,and the controversy still goes on.
