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.

0.05).The titer of HBV DNA is higher in YMDD mutation group than in no mutation group at twelve month or eighteen month with(8.14?0.94)vs(7.29?0.97) and(8.28?0.77) vs(7.17?0.91) respectively.(t=2.33,P10~8copies/ml).

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 investigate the clinical efficacy of acupuncture combined with back Shu acupoint catgut embedding therapy in treating allergic rhinitis. Methods Totally 66 allergic rhinitis patients were included. Random number table method was used to divide the 66 patients into observation group and control group, with 33 cases in each group. The control group was given Ketotifen Fumarate Nasal Drops nose drops 2 drops each time, 3 times a day, Loratadine Tablets 10 mg orally, once a day for 4 weeks. The experimental group was treated with acupuncture, once a day, 10 d as a treatment course, three courses in total; at the same time, back Shu acupoint catgut embedding therapy was given, 15 d each time, twice treatment in total. After the end of treatment, clinical efficacy, clinical symptom score, life quality score, serum levels of inflammatory factors, serum immunoglobulin, peripheral blood eosinophil count and the incidence of adverse reactionsof the two groups were observed. Results The total effective rate was 93.94％ (31/33) in observation group and 75.76％ (25/33) in the control group, with statistical significance in the two groups (P<0.05). Compared with before treatment, the TNSS score, TNNSS score and RQLQ score of the two groups were significantly lower than after treatment (P<0.05); the IgE and EOS levels significantly decreased (P<0.05); the serum IL-17 and IL-22 levels were significantly lower (P<0.05). Compared with the control group, the TNSS, TNNSS and RQLQ score and the levels of IgE, EOS, IL-17 and IL-22 in the treatment group were lower after treatment (P<0.05). There was no significant difference in adverse reactions between the two groups (P>0.05). Conclusion Acupuncture combined with catgut embedding therapy in the treatment of allergic rhinitis has a significant clinical efficacy, which can improve the level of inflammatory factors in patients with high safety.

AIM：To investigate the roles of nitric oxide (NO) and endothelin-1(ET-1) in regulation of coronary vascular reserve (CVR) during hypoxia.METHODS： CVR were measured with 99m TC radiolabelled frog RBC, the changes of NO-2，ET-1 contents， nitric oxide synthase(NOS) activity and the myocardial morphometry were observed. RESULTS： (1) Acute hypoxia caused an increase in left and right ventricular myocardial blood flow，myocardial NO-2，ET-1 contents，NOS activity，but CVR in the left and right ventricle were decreased compared with the control group.(2) Intermittent hypobaric hypoxia for 90 days did not lead to significant change in left ventricular CVR，myocardial ET-1/NO-2 ratio. However, right ventricular myocardial ET-1 contents，ET-1/ NO-2 ratio were increased，right ventricular CVR and myocardial NO-2 contents were decreased. We also observed that perivascular collagen，arterial wall thickness in right ventricle， hematocrit，RV weight index were augmented. CONCLUSION： Rest myocardial blood flow was increased，CVR was decreased；The decreased coronary vascular reserve during chronic hypoxia might be resulted from the increased hematocrit，arterial wall thickness，perivascular collagen，ET-1 content, the decreased NO content and right ventricular hypertrophy

Objective:To construct a recombinant prokaryotic expression vector pGEX-5X-3/hIL-17F and express it in E.coli and to explore the biological activities of human IL-17F fusion protein.Methods:The coding sequence of the mature human IL-17F(minus the signal peptide) was amplified from pUCm-T/hIL-17F by PCR and subcloned into the prokaryotic expression vector pGEX-5X-3 to express glutathione S-transferase(GST) fusion protein. The fusion protein was induced in E.coli BL21 by IPTG and purified by standard methods reported in prokaryotic system. The purified GST-hIL-17F fusion protein was identified by Western blot.
