AIM: To observe the recent curative effect of basic fibroblast growth factor(bFGF) to patients with recurrent aphthous ulcer(RAU). METHODS: 60 patients with RAU were treated by locally spraying compound bFGF preparations composing of calculated quantity of bFGF, tinidazole and dicaine on the surface of ulcerations,?other?40?patients?were?treated?by?alternatively smearing Xi Leisan and Smecta on the surface of ulcerations as routine treatment group, tid, for 5 d. RESULTS: The improvement of three indexes including the size, the degree of ache and hyperemia of the ulcerations are greater in compound bFGF treatment group than those in routine treatment group (P

Objective To explore the role of growth hormone (GH),leptin (Lep),T3,T4,TSH in cord blood in intrauterine growth.Methods 120 healthy newborns (60 males,60 females) were enrolled in this study.The neonates were divided into AGA,LGA and SGA groups according to the relationship between birth weight and gestation.The head circumference,birth length,birth weight,body mass index,biparietal diameter,and placental weight,the levels of GH,Lep,T3,T4,TSH in the cord blood were measured.Results There were significantly statistical differ ences in growth indexs (all P ＜ 0.05),the levels of GH and TSH were significantly increased [(21.52 ± 2.13) ng/L vs (15.64 ± 1.28) ng/L ; (8.6 ± 0.67) mIU/L vs (3.34 ± 0.29) mIU/L,t =3.042,4.367,all P ＜ 0.05] and Lep,T3,T4 were significantly decreased in LGA group when compared with the AGA group [(7.53 ±0.81) g/L vs (9.55 ± 1.26) g/L; (1.25 ± 0.42) nmol/L vs (1.48 ± 0.37) nmol/L; (69.45 ± 10.07) nmol/L vs (76.68 ± 8.22) nmol/L; t =1.749,1.905,1.783,all P ＜ 0.05],the level of Lep in LGA group was significantly higer than that in AGA group [(14.61 ±2.05) g/L vs (9.55 ±1.26) g/L,t =3.064,P ＜0.05].And GH,Lep,T3,T4 were positively correlated with head circumference,birth length,birth weight,body mass index,biparietal diameter,and placental weight (all P ＜ 0.05).TSH was negatively correlated with growth indexs.Conclusion The levels of Lep,T3,T4,TSH in cord blood were associated with fetal growth and could be used as indicators of intrauterine growth.

Objective To investigate the relationship of the C-reactive protein (CRP) and metabolic syndrome.Methods The serum level of CRP was determined in 48 cases of obese children and 36 cases of healthy individuals.All children were 10 years old.The differences between the two groups and whether CRP was associated with metabolic syndrome were analyzed.Results The obese children had significant higher serum insulin,TG,TC,CRP,BMI,SBP and HOMA-IR [for respectively (16.1 ± 3.7) mU/L,(1.38 ± 0.29) mmol/L,(4.79 ± 0.88) mmol/L,(1.83 ± 0.89) mg/L,(28.7 ± 5.3) kg/m2,(129.4-11.3) mmHg,(3.81 ± 0.92)] than those of the normal controls [for respectively(10.4 ±2.8) mU/L,(0.75 ±0.12) mmol/L,(4.12 ± 0.65) mmol/L,(0.78 ± 0.22) mg/L,(22.4 ± 3.9)kg/m2,(117.2 ±8.9) mnHg,(2.37 ±0.78)] (t =7.727,12.260,3.846,6.912,6.012,5.349,7.568,all P ＜0.05).The results of correlation analysis showed that CRP had a positive correlation with serum insulin,TG,BMI,SBP and HOMA-IR (r=0.693,0.293,0.525,0.212,0.195,all P＜0.05),but not TC.Conclusion There are significant increases of serum CRP level in obese children,and the increased CRP was closely related with metabolic syndrome.

Glaucoma is the second leading cause of blindness worldwide.It is mainly caused by glaucomatous optic neuropathy characterized by retinal ganglion cells (RGCs) loss,which leads to visual field loss and blindness.There are many risk factors other than intraocular pressure (IOP) elevation are thought to be responsible for RGCs damage induced by glaucoma,such as neurotrophic factors deprivation,excitotoxicity,oxidative stress and enhanced microglia activity,and these factors are essential for glaucomatous optic neuropathy,especially in normal tension glaucoma (NTG).Up to date,the major attempt of glaucoma therapy is to protect optic nerve function by lowering IOP through surgery and drugs.However,the therapies can not arrest RGCs damage although effectively lowing IOP in a number of patients.Novel study is turning to find and develop some new approaches to solve neuroprotection problem targeting to the pathogenic factors of glaucomatous optic neuropathy out of IOP.This review paper mainly focused on the neuroprotective therapies that are developed in the past few years.

OBJECTIVE:To establish a HPLC method for determination of the content of baicalin in Bifukang oral liq?uid.METHODS:The ODS C 18 column was used with methanol-water-glacial acetic acid(45∶55∶1.5)as mobile phase,and de?tective wavelength was274nm,the flow rate was1ml/min.RESULTS:Within the range of0.215?g～4.3?g,baicalin presented a fine linear relationship between amount and peak area(r=0.9995).The average recovery was99.44%(RSD=0.79%,n=5). CONCLUSION:This HPLC method is convenient,rapid and accurate,and can be used for quality control in the production of Bifukang oral liquid.

Objective To explore the morphology changes of spinal cord after nursing intervention on motor function repair spinal cord injuried rats. Methods 60 adult SD rats were randomly divided into normal control group, experimental control group, and experimental group ( n=20 for each group) . Each group were divided into four time phase points, that is 1 day, 7 days, 30 days and 60 days after spinal cord injury (n=5). The model of L4 plane with full transection of spinal cord were made in the rats in experimental control group and exper-imental group. Normal control group were of untreated normal rats, experimental control group were given routine nursing such as urination and defecation after spinal cord injury, and experimental group were given passive movement practices and muscle massage training twice a day (10 min each time) besides regular nursing. HE staining and immunohistochemistry method were applied to observe the morphology changes of spinal cord. Results In experimental control group and experimental group there was no significant changes in HE staning and NF-200 and GFAP immunohistchemistry staning in spinal cord section of rat at each time phase points, but compared to the normal control group, it was of significant difference. Conclusion There is no apparent change in morphology in injured spinal area after nursing intervention.
