Abstract：

Objective To evaluate the effectiveness of periodontal mechanical therapy on periodontal health and interleukin-6 (IL-6) levels in gingival crevicular fluid (GCF) in type 2 diabetic patients with chronic periodontitis. Methods GCF samples were obtained with filter papers in first molar sites from 37 type 2 diabetic patients with chronic periodontitis. The randomized controlled and blinded clinical trial with a duration of six months was designed to compare effects between three groups of professional mechanical tooth cleaning (PMTC), i.e. coronal scaling (group Ⅱ) with periodontal initial therapy (group Ⅰ) and without clinical therapy (control group). The clinical periodontal index such as probing depth (PD), attachment loss (AL), modified bleeding index (mBI) and bacteria plaque index (PLI) were obtained with a Williams type periodontal probe. Laboratory examination including GCF volume, concentrations and total amounts of IL-6 in GCF were detected with ELISA method. Results Significantly decreasing trends of PD, AL, mBI, GCF volume and total amounts of IL-6 were observed in group Ⅰin all test period. The group Ⅱ had a significant reduction of PD at the third month as compared with baseline (⊿=0.36 mm, P＜0.05), and the other figures showed descending trends but didn′t present statistical significances. At the end of study, the group Ⅰand Ⅱ had significant reductions of GCF volume compared with increases of control group (0.96 μ1＞0.03 μ1mm＞-0.20 μ1, P＜0.05). Conclusions The sequential periodontal supra- and sub- gingival scaling has definitive effects on periodontal health improvement and on reducing the IL-6 level in GCF in type 2 diabetic patients.

Abstract：

Objective To detect the serum level of mannose binding lectin (MBL) in patients with renal injury induced by rheumatoid arthritis (RA), and to investigate the role of MBL in the pathogenesis of renal injury in RA. Methods ELISA was used to measure the serum MBL level of 19 RA patients with renal injury, 49 RA patients without renal injury and 40 healthy individuals. The clinical features and laboratory markers were compared and analyzed by chi-square test, two independent samples t-test and Spearman's correlation analysis. Results Compared with RA patients without renal injury, the number of tender and swollen joints [(15±9) vs (9±11)], duration of morning stiffness [(2.9±1.3) vs (2.3±1.6) h] and extraarticular manifestations (42.1％ vs 16.3％) in RA patients with renal injury were significantly higher (P＜0.05or P＜0.01). There was no significant difference between the two groups in RA disease duration and jointdeformity(P＞0.05). In patients with renal injury, the level of platelet count [(376±155)×109/L vs (304±121)×109/L], CIC[(4.3±3.0) vs (2.9±3.3) g/L], ESR[(79±46) vs (53±31) mm/1 h], RF[(77±42) vs (52±49)U/ml], CRP[(32±28)vs (23±18)mg/L], IgG[(11.7±2.6)vs (8.4±2.4)g/L], C3[(1.18±0.53)vs (0.94±0.21) g/L] were higher than those in RA patients without renal injury (P＜0.01 or P＜0.05); the level of Alb [(26±13) vs (30±9) g/L] was lower than that in RA patients without renal injury (P＜0.05). The level of serum MBL in the two groups of RA patients was significantly lower than that in the healthy group [(3.1±0.5)mg/L](P＜0.01), and the level of serum MBL in RA patients with renal injury [(1.7±1.2) mg/L] was higher than that in RA patients without renal injury [(1.4±1.3) mg/L](P＜0.05). The level of serum MBL in RA patients with renal injury showed a positive correlation with IgG, C3, CRP and 24 h urine protein level (r=0.6, 0.6, 0.47, 0.57; P＜0.05). Conclusion Renal injury in RA patients is immune complex dependent. The serum level of MBL is higher in patients with renal injury, therefore, high-concentration MBL may be one of a potential causes of renal injury in RA patients.

Abstract：

Objective To investigate the cellular immune function changes and the effect of thymosin alpha-1 on the changes in elderly patients with severe pneumonia. Methods T cell subset and natural killer (NK) cell were detected in 66 elderly patients with severe pneumonia and 34 elderly patients with common pneumonia. The severe pneumonia patients were randomly divided into 2 groups: the treatment groups (34 cases) and the control group (32 cases). All patients received conventional therapy of pneumonia. The treatment group received 1.6 mg of thymosin alpha-1 through subcutaneous injection once a day for a week and twice a week later. Results The levels of CD3, CD4, CD8 and NK cell were lower in elderly patients with severe pneumonia than in patients with common pneumonia [(43.54%±18.97%) vs. (45.46%±10.43%), (25.43%±12.72%) vs. (38.47%±8.20%), (16.68%±9.30%) vs. (22.36%±8.06%), (13.52%±4.66%) vs. (17.87%±7.11%), t=-6.779、-5.85、-3.161、-3.285 respectively all P＜0.05]. The levels of CD3, CD4, CD4/CD8 and NK cell increased significantly after treatment in treatment group [(64.22%±5.53%) vs. (61.53%±13.41%), (31.70%±4.38%) vs. (26.07%±4.31%), (1.27%±0.91%) vs. (0.97%±0.22%), (17.67%±4.56%) vs. (15.44%±3.82%), F=5.591,11.526,8.934,4.564 respectively, all P＜0.05]. The duration of antibiotic injection and length of stay were lower in treatment group than in control group [(14.17±2.51) d vs. (14.42±2.79) d, (12.69±2.80) d vs. (15.04±3.58) d, t=-3.152、-2.690 respectively, all P＜0.05]. Conclusions The immune function of the elderly patients with severe pneumonia is lower. Thymosin alpha-1 can improve the immune function of the elder patients with severe pneumonia and is helpful for controlling an infection.     

Inflammatory markers and elderly patients with stroke

C-reactive protein (CRP) is associated with unfavorable outcome in patients with acute ischemicsyndromes and in patients with chronic stable angina.Elevated CRP levels suggestive of heightened inflammatorystate in vascular conditions are often associated with elevated interleukin-6 (IL-6) levels.The aim of our study wasto show the predictive importance of CRP and IL-6 levels in patients with ischemic stroke that has not been fullyelucidated.Design We studied 647 consecutive elderly patients (>65 years) with stroke who were documentedwith ischemic stroke,presence of significant carotid atherosderosis and absence of atrial fibrillation.The studypopulation included 150 patients (74 men,76 women,mean age 74±2).Patients underwent evaluation of highsensitive CRP and IL-6 levels at baseline,during hospitalization and at discharge.Results In-hospital mortalitywas 6%,1 year mertality was 15% and a second cerebrovascular event occurred in 12% of patients.Those with in-hospital events had significantly higher baseline CRP and IL-6 levels than patients without events (3.8+1.1 vs1.9±0.9 mg/L,P<0.01 and 13.8±3.4 vs 6.3±2.1 pg/ml,P<0.01,respectively).Also CRP and IL-6levels were significantly higher in those patients with an event within 3 months of discharge compared to patientswithout an event (3.6±1.3 vs 1.1±0.7 mg/L,P<0.01 and 14.2±3.7 vs 5.4±1.6 pg/ml,P<001,respectively).Both base line CRP levels and IL-6 were predictive of events both in-hospital and after 3 months whileCRP and IL-6 levels at baseline were not associated with a poor 1 year prognosis.Elevated CRP levels wereassociated with an unfavorable outcome only when IL-6 levels were also elevated.In a stepwise multivariate analysisIL-6 level was a stronger predictor of outcome than CRP.Conclusions In conclusion,elevated CRP and IL-6levels may identify elderly patients at increased medium term risk,but do not predict one year events in this subsetof patients.CRP levels predict events only when they are coupled with IL-6 levels.(J Ceriatr Cardiol 2004;1:44-48.)

Methods The 92 elderly patients with T2DM (the elderly group) and 58 young and middle-aged patients with T2DM (the non-elderly group) were monitored using the continuous glucose monitoring system(CGMS). The characteristics of glucose profiles of the two different age groups, and of the different glycosylated hemoglobin (HbA1c) level groups in the elderly were comparatively analyzed. Results (1)There was no significant difference in HbA1c level between the elderly group and the non-elderly group. Compared with the non-elderly group, the elderly group showed the increases in blood glucose fluctuant coefficient [BGFC, (2.68±1.00) mmol/L vs. (2.12±0.74) mmol/L, t=-3.691, P＜0.001], in postprandial glucose excursion (PPGE) of breakfast and supper [(5.96±2.47) mmol/L vs. (5.11±2.44) mmol/L, t=-2.058, P＜0.05; (5.17±2.15) mmol/L vs. (4.16±2.28) mmol/L, t=-2.730, P＜0.01], in the time to postprandial glucose peak of breakfast and lunch [(112.5±29.7) min vs. (97.0±27.2) min, t=-3.225, P＜0.01; (140.0±39.7) min vs. (118.1±42.6) min, t=-3.195, P＜0.01], in the frequency of hypoglycemia (26.3% vs. 5.5%, P＜0.05), and showed the largest amplitude of glycemic excursions [LAGE, (9.66±2.48) mmol/L vs.(8.40±3.13) mmol/L, t=-2.720, P＜0.01]. (2)In the elderly, along with decreased HbA1c, the incidence of hypoglycaemia increased (P＜0.05); And along with increased HbA1c, the amplitude of blood glucose fluctuation increased. There were significant differences in BGFC, PPGE of breakfast and lunch, and LAGE among different HbA1c level groups (P＜0.01, P＜0.05, P＜0.05, P＜0.001). (3)HbA1c was positively correlated with FBG, mean blood glucose (MBG), percentage of time at glycemia (PT7.8, PT11.1), the lowest blood glucose (LBG), the highest blood glucose (HBG), BGFC, PPGE and LAGE (r=0.899-0.289, all P＜0.001). Multiple stepwise regression analysis indicated that MBG, FBG and PT7.8 was the independent influential factor of HbA1c (adjusted R2=0.807, P＜0.05). Conclusions The elderly patients with T2DM are at a particularly high risk for postprandial hyperglycemia and nocturnal hypoglycemic episodes, CGMS could show glucose fluctuation characters of T2DM patients diurnally, and provide a clinical basis for reasonable therapy.

Abstract：

Objective Chronic myocardial ischemia (CMI) has become the most importat cause of heart failure (HF) all over the world. The aim of the current study was to investigate the effects of Sarcoendoplasmic reticulum calcium ATPaee 2a (SERCA2a) gene transfer on cardiac function and endoplasmic reticulum stress (ERS) associated myocardial apoptosis in a minipig HF animal model induced by CMI. Methods HF was induced in minipigs by implantation of ameroid constrictor in the initial segment of left anterior descending (LAD) branch of coronary artery. After confirmation of myocardial perfusion defects and cardiac function impairment by myocardial perfusion imaging and echocardiography, animals were divided into 4 groups (n =4 each): HF group, HF + enhanced green fluorescent protein (EGFP) group,HF + SERCA2a group, and shamed animals as control group. A total amount of 1×1012 v.g. Of rAAV1EGFP or rAAV1-SERCA2a were injected intramyocardially to each animal of HF + EGFP and HF +SERCA2a groups. Sixty days after gene transfer, protein level and activity of SERCA2a were examined,cardiac functions and changes of serum inflammatory and neuro-hormonal factors were determined. Apoptotic index of the ischemic myocardium, protein levels of ER stress marker glucose regulated protein 78 ( GRP 78) and ER stress specific apoptotic marker caspase-12 were also assayed. Results At the study end,echocardiographic and hemodynamic measurements indicated a significant improvement of both cardiac systolic and diastolic function in HF + SERCA2a group compared with HF/HF + EGFP groups [LVEF (60.2±8.6)%vs (44.2±7.1)% and (46.8±6.7)%, Ev/Ay 1.28±0.24 vs 0.77 ±0.17 and 0.80±0.21, +dp/dtmax(2713.9 ±434.0) mm Hg/s ( 1 mm Hg =0.133 kPa) vs (1892.3 ±434.2) mm Hg/s and (1931.2±397.4)mm Hg/s, -dp/dtmax (1422.1±334.4) mm Hg/s vs (848.3±308.3) mm Hg/s and (849.5±278.3)mm Hg/s, P＜0.05], along with increase in both SERCA2a protein level (1.13±0.26 vs 0.73 ±0.17 and 0.64±0.18, P＜0.05) and activity [(16.2±5.5) IU/ml vs (7.9±3.1) IU/ml and (7.5 ±2.8)IU/ml, P ＜0.05] compared with HF/HF + EGFP groups. Serum concentrations of inflammatory factor tumor necrotic factor α [(382.3±114.4) ng/L vs (732.3±201.4) ng/L and (689.8±192 5) ng/L, P＜0. 05], neural-hormonal factors brain natriuretic peptide [(142.6±45.3) ng/L vs (422.3±113.6) ng/L and(393.7 ±103.3)ng/L, P＜0.01], endothelin-1 [(111.4 ±37.5)ng/L vs (193.5 ±54.3)ng/L and (201.0±72.1)ng/L,P＜0.05] and angiotensin Ⅱ[(189.7±65.2)μg/L vs (538.3 ± 135.2) μg/L and ( 525.5±144.1)μg/L, P＜0.01] were also significantly decreased in HF + SERCA2a group compared with HF/HF + EGFP groups. The apoptotic index [(12.71±4.11)% vs(23.22±7.23) % and (24.31±6.38)%, P＜0.05], protein levels of GRP78 (1.27±0.33 vs 3.23±1.14 and 4.18±1.13, P＜0.05)and protein level ratios of cleaved caspase-12 to total caspase-12[(4.62±1.93)% vs (9.71±2.70)% and (10.14±2.81)%, P＜0.05] were also significantly reduced in the ischemic myocardium of HF+SERCA2a group compared with the HF/HF + EGFP groups. Conclusion Overexpression of SERCA2a significantly improved cardiac systolic and diastolic function in this HF model partly through attenuation of ER stress related myocardial apoptosis, suggesting its therapeutic potential for CM1 related heart failure.
