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 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.

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.

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.

Microvesicles (MVs) is small membrane vesicles released from different cell types under different conditions.Studies have shown that MVs may mediate vascular inflammation,angiogenesis,and other pathological processes.MVs may play an important role in the pathogenesis of diabetic retinopathy (DR) by mediating endothelial cell injury,thrombosis and neovascularization.The plasma MV level may be an effective parameter to monitor the development of DR.This article will summarize the research progress of the relationship between MVs and DR in recent years.

Objective To investigate the clinical pathological features and prognosis of gastric carcinoma with neu-roendocrine differentiation (NED) and mixed gonadal neuroendocrine carcinoma of the stomach (MANECs). Methods A retrospective analysis of 61 cases of gastric carcinoma with NED and 34 cases of MANECs and their histochemistry and im-munohistochemistry were also observed. Prognosis of the 2 groups were compared by the Kaplan-Meiers survival analysis. Prognostic factors associated with patients with gastric cancer were analyzed by COX proportional hazards model. Results Tumor location, distant metastasis and lymph node metastasis were statistically different between these 2 groups (P<0.05). Syn positive expression rate is higher than CgA and CD56 in the gastric carcinoma with NED group;Postoperative survive pe-riod of the gastric carcinoma with NED is shorter than that of MANECs (P<0.05). Lymph node metastasis and distant region-al transfer is obviously correlated with prognosis (P<0.05). Conclusion Immunohistochemistry is important for the diag-nosis of these two tumor. The number of neuroendocrine cells can help to assess prognosis and guide treatment.

Resonance frequency analysis(RFA) has been successfully applied to measure the stability of implants, and proved to an objective method. Domestic and international scholars in the field of organ implantation have paid great attention on RFA in recent years. The present paper systematically introduces principles and applications of RFA in buccal medicine. The advantages and insufficiencies of RFA are discussed too.

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.
