0.05). Conclusions The LTs synthesis is elevated in RSV bronchiolitis and LTs may participate in the pathogenesis of RSV bronchiolitis. Leukotriene receptor antagonist may play an important role in RSV bronchiolitis. However there still needs further research on the relationship between LTs and eosinophils count in the pathogenesis of RSV bronchiolitis.
2.Etiology of chronic diarrhea in children
Chinese Journal of Applied Clinical Pediatrics 2015;(19):1441-1443
Chronic diarrhea in children is often accompanied by malnutrition,growth disorders,immune dis-function and repeated infection due to deferment diarrhea and malabsorption of nutrients, which could influence the physical and mental development of children. The etiology and pathogenesis of chronic diarrhea are complex. The causes of chronic diarrhea are different in children with different ages,different regions and countries.
3.Study on heat shock protein 90α and β in peripheral blood mononuclear cells in mayasthenia gravis children treated with glucocorticoid
Journal of Chinese Physician 2015;17(2):243-246
Objective To investigate the expressions of heat shock protein(HSP)90α and HSP90β in peripheral blood mononuclear cells (PBMC) in myasthenia gravis (MG) children before and after glucocorticoid (GC) treatment,and normal control groups.Methods Fresh bloods were collected from 20 cases of children with MG before and after treatment and 19 healthy children.PBMCs were isolated,followed by measurement of the expression levels of HSP90α and β by immunocytochemistry,and HSP90α and β mRNAs by reverse transcription and polymerase chain reaction (RT-PCR).Results The positive cell ratio of HSP90α andβ of MG children before and after of GC treatment was significantly higher than control groups (P < 0.05),and their mRNA expression levels was higher than control groups (P < 0.05).HSP90β in MG children after GC treatment was mainly expressed in the nucleus(P < 0.05).Conclusions HSP90α and β in PBMC of MG children before and after GC treatment were significantly higher than those of normal control groups.HSP90β in MG Children after GC treatment was significantly increased.The present results suggest HSP90β promote GC receptor binding and enhance GC transportation,which promotes and strengthens the physiological and pharmacological effects of GC to improve the clinical symptom of MG children.
4.Binding capacity of nano-hydroxyapatite/polyamide composite material on the interface of artificial humeral head
Chinese Journal of Tissue Engineering Research 2015;19(30):4764-4768
BACKGROUND:Nano-hydroxyapatite/polyamide 66 is a new nanobionic composite material and has good biocompatibility and bone conduction, but after implantation, whether the composite material can bind to vertebral bone interface and whether it is safe in clinical use stil need further studies. OBJECTIVE: To observe the ability of nano-hydroxyapatite/polyamide composite binding to the interface of artificial humeral head. METHODS: The rabbits were randomly divided into two groups: composite group was implanted with nano-hydroxyapatite/polyamide composites; control group implanted with autologous bone. After the replacement, rabbit bone marrow mesenchymal stem cels were subjected to primary culture, and then the cels were co-cultured with the composite material. RESULTS AND CONCLUSION:At 24 hours after culture, bone marrow mesenchymal stem cels grew wel on the composite materials. The cel adhesion rate was significantly higher in the composite group than the control group at 1 and 4 hours after culture (P < 0.05). After co-culture 4.5, 5.5, 6.5 hours, the absorbance value of cels in the composite group was higher than that in the control group (P < 0.05). At 24 weeks after replacement, changing ranges in the proportions of bone tissue and fibrous layers on the implant surface as wel as coverage rate in the composite group were the highest (P < 0.05). These findings indicate that the nano-hydroxyapatite/ polyamide composite implant has a certain binding capacity, which can make a good interface osseointegration.
5.Detection of Lead Ions in Water Based on Surface Energy Transfer between Gold Nanoparticles and Fluorescenct Dyes
Chinese Journal of Analytical Chemistry 2014;(8):1196-1200
We established a sensitive method for the detection of lead ions in aqueous solution based on the surface energy transfer between gold nanoparticles and fluorescent dyes. The fluorescein-modified thrombin aptamer (5′-FAM-GGT TGG TGT GGT TGG-3′) can be selectively transformed to G-quadruplex induced by lead ions. The conformation changes of the aptamer can alter the distance between the energy donor of fluorescent dyes and the energy receptor of gold nanoparticles, and further enhance the fluorescence intensity. The fluorescence recovery efficiency ( F/F0 ) is proportional to the concentration of lead ions in the range of 12. 5-100 nmol/L following the linear regression equation of y=0. 910﹢0. 007c(R2=0. 997)and the limit of determination is about 10 nmol/L. The proposed method has been applied to the determination of lead ions in tap water with satisfied results.

8.Comments on health care theories of "disease prevention" and "health preservation from both physique and spirit "
China Journal of Traditional Chinese Medicine and Pharmacy 2006;0(09):-
The potential advantage of Traditional Chinese Medicine(TCM) theories of disease prevention,especial the thinking mode of "health preservation from both physique and spirit "has been generally recognized and widely understood by international society increasingly.In TCM,methods of disease prevention are various and the "health preservation from both physique and spirit" is praised the highest.This article demonstrates the theory that preserving the spirit firstly and then combining with physique,also the methods of keeping an undisturbed spirit and protecting the physique from any harm,for the purpose to make new contribution to the mankind’s health-care industry.
9.Effects of Bacille Calmette Guerin on immunological function of infants with bronchiolitis
Chinese Journal of Clinical Pharmacology and Therapeutics 2000;0(03):-
AIM:To approach the effects of Bacille Calmette-Guerin(BCG)on immunological function of infants with bronchiolitis in vitro. METHODS: The monocytes were segregated from the peripheral blood of infants with acute bronchiolitis and healthy infants as control. The cytokines of IL-10 and IL-12 were measured by ELISA after interfered with different concentrations of BCG in vitro. IL-4, produced by lymphocytes treated with the cultural supernatant of BCG-stimulated monocytes were determined by ELISA. Acute bronchiolitis infants and health children treated with normal saline were as control. RESULTS: BCG stimulated IL-10 and IL-12 production in a dose response manner in a certain concentration range. The higher level of IL-10 was observed when BCG concentration reached 50 ?L/mL, while IL-12 had no significant increase. The level of IL-4 was markedly decreased compared with pre-treatment (P
10.Allogeneic hematopoietic stem cell transplantation for myelodysplastic syndrome
Chinese Journal of Practical Internal Medicine 2001;0(05):-
The indications for patients with Myelodysplastic Syndrome (MDS) to receive allogeneic hematopoietic stem cell transplantation (Allo-HCT) are:intermediate risk-2 and high risk groups according to IPSS,and intermediate risk-1 group with poor karyotype,severe multilineage cytopenia or infusion-dependent.Constant follow-up and evaluation is important for therapeutic decision.Unrelated or related haploidentical donor could be an alternative in case of absence of identical sibling donor.Remission through chemotherapy before the transplantation is recommended in patients with advanced MDS who receive reduced-intensity conditioning.Demethylation drugs followed by Allo-HCT do not show additional transplantation-related toxicity,whose efficiency remains to be determined.
