Objective · To detect gingival thickness of the anterior teeth region of Han nationality youths in Shanghai by cone-beam computerized tomography (CBCT), and evaluate its clinical application feasibility and the gingival biotype. Methods · Firstly, gingival thickness in the same site (5 participators, 30 sites) was detected by bone sounding and CBCT respectively, and the data were compared. A total of 30 participators with healthy gingival were recruited to the study and examined by the CBCT, the gingival thickness of selected sites (330 sites) was assessed and compared. All the subjects were examined by the experienced doctors and classified into three groups, thick-type middle-type and thin-type. Gingival thickness range and the proportion of every type were obtained. All data analyses were performed using SPSS 13.0. Results · There was no statistical difference in the thickness of gingival measured by bone sounding and CBCT (P>0.05). The main gingival biotypes of Han nationality youths in Shanghai were thin-type and middle-type. The average gingival thickness of upper central incisors [(1.32±0.15) mm] was larger than those of upper lateral incisors [(1.07±0.16) mm,P=0.000] and upper canines [(1.08±0.18) mm, P=0.000]. Conclusion · CBCT is feasible for detecting gingival thickness. Gingival thickness of the upper central incisors is significantly larger than those of upper lateral incisors and upper canines. The main gingival biotype of Han nationality youths in Shanghai is middle-type, the proportion of thick-type is least.

Objective · To establish a replicative senescence model of human gingival fibroblasts (hGFs), investigate changes in aging related biological characteristics, and provide an efficient cell model for further study on the aging in periodontal diseases. Methods · hGFs were isolated from healthy gingival tissues and cultured with tissue block method in vitro. The tissue source was verified with immunofluorescence. hGFs were continuously cultured and cumulative population doublings (CPD) were calculated and used to draw the curves. Changes in the proliferative capacity of hGFs with CPDs of 10.82, 20.65, 29.52, 42.22, 60.79, and 70.03 were examined with CCK-8. Real-time PCR was used to evaluate changes in the mRNA expression of senescence-related genes p16INK4a and p21Cip1. Results · CPD curves showed that after continuous culture, the CPD value increased gradually and became stable after achieving 70.03. hGFs became flatter and more cell rocessesappeared with the increase of CPD value. The cell proliferative capacity declined and mRNA levels of p16INK4a and p21Cip1 significantly increased (P=0.000). Conclusion · A replicative senescence model of hGFs is established throughcontinuous culture. CPD curves can reflect the aging of hGFs.

Objective To evaluate the effects of nucleoside/nucleotide analogue treatment on immunoglobulin and complement in patients with chronic hepatitis B (CHB).MethodsA total of 157 CHB patients were recruited and divided into CHB group,liver cirrhosis (LC) group and severe hepatitis B (SHB) group.There were 50 patients who received oral antiviral treatment (lamivudine 100 mg/d,or entecavir 0.5 mg/d,or telbivudine 600 mg/d).Serum levels of complement 3 and 4 (C3,C4),C-reaction protein (CRP),hemolytic complement (CH50),immunoglobulin G,M,A (IgG,IgM,IgA),hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) were detected by enzyme-linked immunosorbent assay (ELISA) or immunoturbidimetry.Hepatitis B virus (HBV) DNA was quantified by real-time polymerase chain reaction (RT-PCR) before and 1,2,3 and 4 weeks after nucleoside antiviral therapy.Comparison of means was done by t test and Mann-Whitney test.The correlation was analyzed by Pearson correlation coefficient test.ResultsSerum IgA and IgM levels of SHB and LC patients were significantly higher than those of CHB patients (P<0.01).Levels of C3,C4,CH50 and CRP were significantly different among three groups.Levels of C3,IgM,IgG and HBV DNA in HBeAg positive patients were significantly different from those in HBeAg negative patients.There was a statistically significant difference of IgA,IgM,C3 and CH50 levels between patients with high HBV DNA level and low HBV DNA level in HBeAg-positive patients.While in the HBeAg-negative patients,only the IgA level was significantly different with HBV DNA levels.After anti-viral treatment,immunoglobulin and HBV DNA levels were all decreased in three groups,while the serum complement level was increased compared to baseline,and the differences became significant at week 4 of treatment. HBV DNA level was negatively correlated with C3 (r=-0.78,P=0.021) and HBeAg titer was positively correlated with C3 (r=0.87,P=0.015).ConclusionsThe immunoglobulin,CRP,C3,C4,and C H50 could reflect the inflammatory activity in liver.The changes of C3 level can predict the efficacy of antiviral therapy.

Objective To study the clinical characteristics and HBeAg status in HBV liver cirrhosis patients with different HBV DNA levels, Method Three hundred and thirty-seven patients with liver cirrhosis caused by chronic HBV infection were investigated. HBV DNA levels were detected by PCR, and HBV markers were detected by MEIA. The ratio of patients with HBeAg positive or negative in groups with different HBV DNA levels was compared, and the clinical characteristics in patients with different HBV DNA levels and HBeAg status were evaluated. Results The positive ratio of HBV DNA and HBeAg were 80.4% (271/337) and 31.5% (106/337). The negative ratio of HBeAg was 68.5% (231/337). The proportion of patients with Child-Pugh grade A, B or C and hepatocellular carcinoma (HCC) in different groups of HBV DNA levels and in different HBeAg status showed no significant difference, but the ratio of HCC in patients with HBV DNA 3-4 lg copies/ml was higher than that in patients with HBV DNA <3 lg copies/ml (P=0.014) and ≥7 lg eopies/ml (P =0.009). No significant difference of HBV DNA levels was found in different age groups, but the negative ratio of HBeAg increased with the increasing of the age. Conclusions More than 80% of patients with liver cirrhosis caused by chronic HBV infection axe HBV DNA positive, and 2/3 of them are HBeAg negative. Suppressing HBV replication may improve the prognosis of HBV related cirrhosis and HCC.

AIM: To explore the mechanism of ET-1, NO and PGI 2 release from coronary artery endothelial cells (CAEC) induced by acute hypoxia. METHODS: Bovine coronary artery endothelial cells were cultured and [ 45 Ca 2+ ] was used to investigate the difference of calcium uptake between normoxia group and hypoxia group (3% O 2). The contents of ET-1, NO and PGI 2 in media of normoxia group, hypoxia group and hypoxia + verapamil group were measured 24 h after hypoxia. RESULTS: [ 45 Ca 2+ ] uptake by CAEC in hypoxia group was 1.9 times more than normoxia group ( P

Objective To evaluate the effectson experimental posterior vitreous detachment(PVD) induced by intravitrous injection of hyaluronidase and perfIuoroethane(C3F8),and whether it is safe or not.Methods Twelve rabbits(24 eyes) were divided into 3 experimental groups,the contralateral eyes in same animals served as the controls.The eyes in group A(4 eyes) and B(4 eyes) were injected with 10IU of hyaluronldase(0.2ml) and 0.2ml perfluoropropane(C3F8) respectively.The eyes in group C(4 eyes) were received vitreous injections of 10IU(0.1ml) of hyaluronldase and 0.1ml perfluoropropane(C3F8) together.All control eyes were injected with balanced salt solution(0.2ml).The ocular and fundus signs were examined for 2 following weeks and then killed for histological examination.Results Four eyes in group C showed complete separation of the vitreous cortex from the retina(PVD) by B-scan and scanning electron microscopy,and no PVD was detected in group A、B and all control eyes.No evidence of retinal toxicity was revealed by light or transmisson electron microscopy in all eyes.Conclusion Vitreous injection of hyaluronidase combined with perfluoropropane(C3F8),as a safety method,can induce posterior vitreous detachment after 2 weeks.
