Objective To investigate the expression of NF-k B and c-myc in keratinocytes of HPV infected condyloma acuminata (CA) lesions.Methods Fifty cases of HPV 6/11 positive CA were diagnosed by in situ hybridization.The expression and distribution of NF-k B and c-myc were detected by immunohistochemistry technique (EnVision) with CA lesions and 25 normal human skins (foreskins). Results②The expression of NF-k B and c-myc was significantly higher in keratinocytes of CA lesions than those of normal controls (P＜0.01 ).NF-k B was mainly expressed in spinous layers of CA lesions, and most positive signals located significantly in the cytoplasm.C-myc was mainly expressed in the whole epidermis or in spinous and basal layers in CA lesions,and positive signals located in the nuclei.②There was a positive correlation between the expression of NF-k B and c-myc in CA lesions (r=0.89,P＜0.01).Conclusions The study demonstrates that the expression of both NF-k B and c-myc is significant- ly higher in HPV 6/11 positive CA than in normal skin.The data suggest that transcriptional factor NF-k B and c-myc may play a role in the regulation of proliferation of HPV 6/11 infected cells.

Objective To compare the effect of cimetidine associated with bletilla striata,rhubarb on peptic ulcer,cushingulcer,acute erosive gastritis,bleeding of esophagus and gastric funds varicosis of cirrhotic portal hyper- tension and gastri cancer.Methods 136 patients with upper gastrointestinal hemorrhage were randomly divided into 2 groups.The treated group(n=69)was given cimitidine associated with bletilla striata,rhubarb and the control group(n=67)was given cimitidine only.The effects of hemostasis in 2 groups were observed.Results The effect of hemostasis in the treated group was better than that in the control group on peptic ulcer,cushingulcer,acute ero- sive gastritis and gastric cancer(P＜0.05).There were no difference between 2 groups about bleeding of esophagus and gastric funds varicosis of cirrhotic portal hypertension(P＞0.05).Conclusion The effect of hemostasis on up- per gastrointestinal hemorrhage treated by integrated traditional Chinese medicine and western medicine might achieve better on cushingulcer,acute erosive gastritis,peptic ulcer and gastri cancer.It has less adverse effect and more safety.

Objective To investigate the daily total fluoride intake in relating to the prevalence of skeletal fluorosis in two villages in Jiangsu Province,in order to provide the scientific evidences for the control and prevention of endemic fluorosis.Methods Adults sampled from a high-fluoride Village,Wamiao,and a low-fluoride Village,Xinhuai,were surveyed in this study according to the fluoride concentration in their household shallow well.The average daily total fluoride intake from difierent sources and the skeletal fluorosis were investigated in each subject.Then the subjects from two villages were allocated into five subgroups(＜2.00,2.00～,3.00～,4.00～,≥5.00 mg/d),the relation fluoride intake and prevalence of osteofluorosis was analyzed.Results The prevalence of skeletal fluorosis in Wamiao Village was 31.06%(41/132),but no skeletal fluorosis case(0/35)was found in Xinhuai Village.According to the daily total fluoride intake,subjects with higher daily total fluoride intake tended to associated with a higher prevalence of skeletal fluorosis in a significant dose-response relationship(regression equation:y=2.624-6.855x+3.424x2:r=0.997).The benchmark dose lower limitation of daily total fluoride intake with 95% confidencewas 2.50 mg/d calculated according to this dose-response relationship,the reference dose(RfD)was 2.50 mg/d.In Wamiao Village a significant difference was also found between daily total fluoride intake in 41 subjects[(5.09±1.20)mg/d]with X-ray detectable skeletal fluorosis and in 91 subjects[(3.08±1.12)mg/d]without X-ray detectable skeletal fluorosis(t=-9.32,P＜0.01).Conclusions These findings indicate that the daily total fluoride intake has a significant dose-response relationship with the prevalence of skeletal fluorosis in an endemic fluorosis area associated with high-fluoride drinking water;and the RfD in this study was lower than that in the national standard of"Chinese hygienic standard for daily total fluoride intake(WS/T 87-1996)"(3.50 mg/d).

Objective To discuss the risks of hypertension development with relation to the level of lipid variables among populations who had normal blood pressure at baseline study. Methods In April 2000, under the support of project "prevention of metabolic syndrome and multi-metabolic disorders in Jiangsu province", a cohort study was performed to obtain the baseline data among 8685 persons from age 34 to 74. In June of 2006, a follow-up investigation was carried out among those who had been in the study for 5 years after the baseline study started. 2603 persons who met the selection criteria and showed normal blood pressure during baseline study, were recruited in this investigation. The interval from the baseline to the follow-up studies was 6.38 years on average. Relationship between the risk of developing hypertension and the baseline level of lipid variables were analyzed. Results Relations between baseline lipid levels and the incidence of hypertension during the follow-up was discovered. In gender and age adjusted model, the lipid variables were all associated with hypertension(Wend test, P<0.01). In multivariable-adjusted model, HDL-C [aRR=0.71 (95%CI: 0.61-0.99)], non-HDL-C [αRR=1.28 (95%CI: 1.14-1.83)], TC/HDL-C ratio[aRR=1.41 (95%CI: 1.25-2.03)] and TG [αRR=1.49(95%CI: 1.30-2.13)] were again associated with hypertension (trend test, P<0.05). Even the αRR was much weakened after the baseline SBP, DBP were adjusted with Cox model, the significant relation of hypertension to HDL-C, TC/HDL-C ratio and TG still existed. Excluding the two factors of obesity (BMI≥28) and diabetes which had been recognized in marked linking with hypertension, lipid variables were still associated with hypertension. Conclusion Dyslipidemia might occur before being hypertensive. Hypertension was associated with HDL-C, TC/HDL-C and TG or even exclusion of obesity, diabetes and factors of smoking and drinking or baseline level of SBP, DBP were adjusted.
