OBJECTIVETo detect the presence of Porphyromonas gingivalis (Pg) and Actinobacillus actinomycetemcomitans (Aa) using polymerase chain reaction (PCR) in the oral plaque samples from children and investigate the relationship between bacteria and clinical parameters.

METHODSA total of 151 children aged 7 to 12 years were selected from Changchun Ziqiang primary school. The supragingival plaque sample was collected from the mesiobuccal and labial surfaces of the right maxillary central incisor and the right maxillary first molar. Extracted DNA from plaque samples was used for PCR analysis. Intraoral examination, probing depth (PD) and bleeding on probing (BOP) were performed and recorded.

RESULTSThe detection rate for Pg was 27.6% and Aa 54.3% in supragingival plaque. The detection rates for Pg in molars were much higher than those in incisors (P < 0.01). The detection rate of Pg was positively related to BOP+ and PD. The detection rate for Pg increased gradually with aging, and the detection rate for Aa was highest in the group aged 11 to 12 and the detection rates for Pg and Aa were higher in the gingiva with BOP+ than that with BOP- (P < 0.05). The detection rates for Pg increased remarkably with BOP+ and especially when PD was greater than 4 mm.

CONCLUSIONSDetection rates of putative periodontal pathogens from healthy children of 7 to 12 years of age were high. The detection rates for Pg in molars were much higher than those in incisors,and the presence of Pg and Aa in supragingival plaque was related to periodontal parameters.

BACKGROUNDPatients with end-stage renal disease have a high mortality from coronary artery disease, but the impact of moderate renal insufficiency on clinical outcomes after percutaneous coronary intervention (PCI) and the effect of drug-eluting stent implantation in these patients remain unclear. This study determined the long-term effect of moderate renal insufficiency on death and major adverse cardiac events (MACE) after stent based PCI and examined whether drug-eluting stent implantation could favourably influence clinical outcome.

METHODSMajor adverse cardiac events and causes of mortality were determined for 1012 patients undergoing percutaneous intervention from January 1, 2002 to December 31, 2004 at Shanghai Ruijin Hospital. Based on estimated creatinine clearance levels, long term outcomes were compared between patients with estimated creatinine clearance < 60 ml/min (renal insufficiency group; n = 410) and those with estimated creatinine clearance > or = 60 ml/min (control group; n = 602). Subgroup analysis was also made for patients with renal insufficiency between drug eluting stent (n = 264) and bare metal stent implantation (n = 146) during PCI.

RESULTSDuring follow-up (average 17 months) after successful PCI, all causes of death (7.1% vs 2.3%, P < 0.01) and cardiac death (3.4% vs 1.0%, all P < 0.01) were significantly higher in renal insufficiency group than in control group. For patients with moderate renal insufficiency, drug-eluting stent implantation reduced significantly all causes of death (5.3% vs 10.9%, P < 0.05) and occurrence of major cardiac adverse events (15.1% vs 24.6%, P < 0.05) compared with bare metal stents.

CONCLUSIONSModerate renal insufficiency is an important clinical factor influencing the mortality after PCI in patients with coronary artery disease and the use of drug-eluting stents should be the preferred therapy for the improvement of long-term outcomes in such patients.

OBJECTIVETo review our experience with endoscopic endonasal approach for surgical management of clival tumors.

METHODSTwenty-four patients with clival tumors treated by endoscopic endonasal surgery between August 2002 and November 2005 were studied prospectively. The operative technique was described in detail. There were 5 chordoma, 2 ossifying fibroma, 1 meningioma, 1 craniopharyngioma, 1 hemangioblastoma, 6 squamous cancer, 2 chondrosarcoma, 2 chondrosarcoma, 1 lymphoma, 1 malignant giant cell tumor and 2 metastatic carcinoma.

RESULTSTotal tumor removal was obtained in 22 cases, subtotal removal in 2 case. Follow-up ranged 12 to 51 months. Three patients dead. Five patients with total removal recurred, one of them dead. Two patients with subtotal removal dead, one with chondrosarcoma and one with chordoma. The complications included subarachnoid hemorrhage in 1 patient, and transient cerebrospinal leakage in 2 cases.

CONCLUSIONSThe use of nasoendoscopy to perform clival tumor surgery is not only limited to the minimally invasive aspect, it also provides better visualization of deeper structures in the skull base, provides the ability to 'look around corners' and wide exposed field. This approach permits us to manage clival lesions properly.

The study was designed to explore the drug-drug interactions mechanisms mediated by OATP1B1 between traditional Chinese medicine Danshensu and rosuvastatin. First, the changes of rosuvastatin pharmacokinetics were investigated in presence of Danshensu in rats. Then, the primary rat hepatocytes model was established to explore the effects of Danshensu on the uptake of rosuvastatin by hepatocytes. Finally, HEK293T cells with overexpression of OATP1B1*a and OATP1B1*5 were established using a lentiviral delivery system to explore the effects of Danshensu on the uptake of rosuvastatin. Rosuvastatin pharmacokinetic parameters of C(max0, AUCO(0-t), AUC(0-∞) were increased about 123%, 194% and 195%, by Danshensu in rats, while the CL z/F value was decreased by 60%. Uptake of rosuvastatin in the primary rat hepatocytes was decreased by 3.13%, 41.15% and 74.62%, respectively in the presence of 20, 40 and 80 μmol x L(-1) Danshensu. The IC50 parameters was (53.04 ± 2.43) μmol x L(-1). The inhibitory effect of Danshensu on OATP1B1 mediated transport of rosuvastatin was related to the OATP1B1 gene type. In OATP1B1*5-HEK293T mutant cells, transport of rosuvastatin were reduced by (39.11 ± 4.94)% and (63.61 ± 3.94)%, respectively, by Danshensu at 1 and 10 μmol x L(-1). While transport of rosuvastatin was reduced by (8.22 ± 2.40)% and (11.56 ± 3.04)% and in OATP1B1*1a cells, respectively. Danshensu significantly altered the pharmacokinetics of rosuvastatin in rats, which was related to competitive inhibition of transport by OATPJBI. Danshensu exhibited a significant activity in the inhibition of rosuvastatin transport by OATP1B1*5-HEK293T, but not by OATP1B1*1a, suggesting a dependence on OATP1B1 sequence.

OBJECTIVETo detect the presence of Tannerella forsythus (Tf) and Prevotella intermedia (Pi) using polymerase chain reaction (PCR) in the oral plaque samples from children and investigate the relationship between bacteria and clinical parameters.

METHODSA total of 151 children aged 7 to 12 years were selected from Changchun primary school. The supragingival plaque sample was collected from the mesiobuccal and labial surfaces of the right maxillary central incisor (FDI1) and the right maxillary first molar (FDI6). Extracted DNA from plaque samples was used for PCR analysis. Intraoral examination, probing depth (PD) and bleeding on probing (BOP) were performed and recorded.

RESULTSThe detection rate for Tf was 40.3% (118/293) and Pi was 46.4% (136/293) in supragingival plaque. The detection rates for Tf and Pi in molars were much higher than those in incisors (P < 0.01). The detection rate of Tf and Pi was positively related to BOP+ and PD. The detection rate for Pi decreased gradually with age, and the detection rate for Tf was highest in the group aged 7 to 8 and the detection rates for Tf and Pi were higher in the gingiva with BOP+ than that with BOP- (P > 0.05). The detection rates for Tf increased remarkably with BOP+ and especially when PD was greater than 4 mm.

CONCLUSIONSDetection rates of putative periodontal pathogens from healthy children of 7 to 12 years of age were high. The detection rates for Tf and Pi in molars were much higher than those in incisors, and the presence of Tf and Pi in supragingival plaque was related to periodontal parameters.

BACKGROUNDThe adverse health effects of lead for children under 6 years are well known. Studies to assess the lead exposure among children in China are small in sample size and lack of national representative data. The aim of this study therefore was to describe blood lead levels and identify risk factors for lead exposure among children aged 0 to 6 years living in 16 cities in China.

METHODSWe analyzed data from blood lead levels surveillance in China carried out in 16 large cities between 2004 and 2008. A stratified clustered random sampling strategy was used. A total of 69 968 children aged 0 to 6 years were included. We conducted multiple Logistic regression analyses to explore risk factors to high blood lead level.

RESULTSThe geometric mean blood lead level of the children was 4.50 µg/dl (median: 4.90 µg/dl; IQR: 3.20 - 7.00 µg/dl). Overall prevalence of blood lead level ≥ 10.00 µg/dl among 0- to 6-year-old children was 7.57%. But the proportion of blood lead level ≥ 5.00 but < 10.00 µg/dl was 42.12%. Blood lead levels were significantly higher in boys (4.63 µg/dl) than in girls (4.35 µg/dl) (P < 0.0001). The geometric mean blood lead levels and prevalence of blood lead level ≥ 10.00 µg/dl increased with age (P < 0.0001 for the two trends). After controlling for sociodemographic, dietary and behavior factors, multivariable analysis indicated that lower maternal education, male gender, younger age, often biting pencil or/and toys, walking or playing for long time on the street, not washing hands before eating are major risk factors for higher lead levels.

CONCLUSIONSThe blood lead levels among Chinese children in urban areas are lower than previous studies but close to those of developed countries. However, children with low lead exposure account for almost half and the sociodemographic factors (age, male sex, and low mother education level) continue to be associated with higher blood lead levels.

OBJECTIVETo evaluate the value of transbronchial needle aspiration (TBNA) combined with transesophageal endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in the diagnosis of mediastinal and pulmonary hilar lesions as well as in the lymph node staging (N staging) of lung cancer.

METHODS129 patients with mediastinal and pulmonary hilar lesions underwent either TBNA or EUS-FNA with cytological needle aspiration. The samples obtained from TBNA or EUS-FNA were examined by both cytologiy and histopathology.

RESULTSOf the 129 patients, 59 underwent TBNA and 70 EUS-FNA. The diagnostic rate were 84.7% (50/59) by TBNA and 94.3% (66/70) by EUS-FNA, resepectively. The diagnosis of 116 (89.9%) patients were confirmed by either TBNA or EUS-FNA. The pathological and cytological diagnostic rates were 92.2% (107/116) and 88.0% (102/116), resepectively. The diagnostic rate was elevated by 8.4% (9/107) through pathological examination. The histological classification rates by cytological and pathological examination were 73.8% (76/116) and 89.3% (92/103), respectively. The diagnostic rate of histological classification was elevated by 35.5% (27/76) through pathological examination.

CONCLUSIONThe combination of TBNA and EUS-FNA can improve the diagnostic rate for wider mediastinal and pulmlonary hilar lesions. Pathological examination of the samples obtained from the TBNA and EUS-FNA can elevate not only the rate of diagnosis but also the rate of histological classification.

BACKGROUNDChronic obstructive pulmonary disease (COPD) has a variable natural history and not all individuals follow the same course. This study aimed to identify the prevalence and characteristics of asymptomatic COPD patients from a population-based survey in China.

METHODSA multistage cluster sampling strategy was used in a population from seven different provinces/cities. All residents (over 40 years old) were interviewed with a standardized questionnaire and spirometry. Post-bronchodilator forced expiratory volume in 1 second (FEV(1))/forced vital capacity (FVC) of less than 70% was defined as the diagnostic criterion of COPD. All COPD patients screened were divided into symptomatic group and asymptomatic group according to the presence or absence of chronic respiratory symptoms. Socio-demographic, personal and exposure variables were collected and analyzed.

RESULTSAmong the 1668 patients who were diagnosed with COPD from the 25 627 sampling subjects, 589 (35.3%) were asymptomatic. The age, sex, body mass index (BMI), rural and urban distributions, smoking habit and education levels were similar in the two groups. A total of 64.7% of the asymptomatic patients had no comorbidities. Cardiovascular diseases and lung cancer were more common among symptomatic COPD patients than asymptomatic group. Asymptomatic COPD group were less likely to present with poor ventilation in the kitchen, a family history of respiratory disease and recurrent childhood cough. Asymptomatic COPD patients had significantly higher FEV(1) (73.1% vs. 61.0%), FVC (91.9% vs. 82.0%), and a higher ratio of FEV(1)/FVC (62.9% vs. 58.7%) (all P < 0.001) than symptomatic group. More asymptomatic patients were underdiagnosed (91.9% vs. 54.3%, P < 0.001) than symptomatic patients.

CONCLUSIONSThis large population-based survey confirmed a high prevalence of asymptomatic COPD patients in China. More use of spirometry screening test may be important to the early detection of COPD.

OBJECTIVETo investigate the value of narrow band imaging (NBI) endoscopy in the detection of laryngeal cancer and its precursor lesions.

METHODSBetween December 2008 and July 2009, a total of 122 consecutive patients with suspected precancerous or cancerous lesions of the larynx were enrolled in this study. High performance endoscopic system equipped with the white light mode and NBI mode was introduced in the examination of larynx. Full pharyngeal and laryngeal examination was performed first under white light endoscope and then under NBI. Each lesion was observed by NBI endoscopy and classified according to the detailed morphologic findings of epithelial microvessels. Histological results were then compared to the corresponding white light and NBI images.

RESULTSAmong the 122 patients, a total of 149 lesions were detected by white light and NBI modes. The histological diagnoses of these lesions were as follows: 16 laryngeal polyp, 7 laryngitis, 24 simple hyperplasia, 17 mild dysplasia, 6 moderate dysplasia, 6 severe dysplasia, 9 carcinoma in situ, 64 invasive cancer. The diagnostic accuracy by NBI for the laryngeal lesions was 90.6% (135/149), which was significantly higher than that of white light (75.2%, 112/149, chi² = 12.514, P < 0.001). The sensitivity of NBI and white light to detect laryngeal carcinoma was 93.2% (68/73) and 68.5% (50/73), respectively (chi² = 14.317, P < 0.001).

CONCLUSIONSNBI endoscopy was a promising tool for the differentiation of non-malignant from malignant laryngeal lesions in vivo by detection of the morphology of mucosal capillary vessels. NBI endoscopy was easy to application in the routine pharyngolaryngeal examination with high sensitivity, and facilitated to improve the abilities of preoperative diagnosis and postoperative surveillance.
