Objective To investigate the prevalence and risk factors of metabolic syndrome (MS) in residents in Pudong New District of Shanghai. MethodsA total of 5 584 residents aged 20-80 years were randomly selected from Pudong New District of Shanghai through multistage sampling and interviewed from April to July of 2008. Metabolic syndrome was defined according to three diagnostic criteria for MS, issued by the modified National Cholesterol Education Program Adult Treatment Panel Ⅲ criteria ( NCEP-ATP Ⅲ ), International Diabetes Federation (IDF), and Chinese Diabetes Society (CDS). ResultsThe crude prevalences of MS in the adult population in Pudong New District were 18.2％ and 13.1％ standardized ( male 19. 1％, female 17.4％, the age-standardized 15.6％ and 13.2％ ) with CDS criterion, 31.8％ and 24.4％ standardized ( male 28.4％ ,female 35.1％ ,the agestandardized 22. 7％ and 25.0％ ) with NCEP-ATP Ⅲ criterion, and 21.7％ and 17.0％ standardized ( male 15.9％ ,female 26.7％, the age-standardized 13.8％ and 19.2％ ) with IDF criterion. The age-specific prevalence of MS increased according to three diagnostic criteria, and the age-adjusted prevalence was higher in males than females in junior age groups and higher in females than males in senior ones. Significant differences were present among region, education, marriage status, smoking, work intensity, recreation, and physical activity according to some diagnostic criteria. ConclusionsSubstantial proportions of adults in Pudong New District of Shanghai suffer from metabolic syndrome, and there exists a tendency for young people involved. MS has become a noteworthy public health problem. It suggests that community-integrated control strategy of MS should be made a priority.

0.05). Two fasting blood samples of 3 mL were taken in both groups and were sealed in tubes.Serum was separated by centrifugation at 3 000 r/min for 10 min.

Event-related potential (ERP) studies report that early components P120, N170 and VPP are associated with face processing. Several lines of evidence suggest that VPP is the positive counterpart of N170, and they are generated by the same brain sources. However, whether P120 has a negative counterpart and the relations among these early components (i.e. P120, N170, VPP) remain unclear. In this study, the scalp electroencephalogram was recorded when the subjects passively viewed different stimuli, and ERP was calculated. The synchronization of electroencephalography signals between fronto-central and bilateral occipitotemporal sites was evaluated, and independent component analysis was employed to seek the face-sensitive independent components and their corresponding sources. We found that P120 had the negative counterpart, i.e., VN120; moreover, VN120-VPP and P120-N170 complexes were generated by the same sources located in fusiform gyrus, which reflected the same sequential neural activities of face processing.

OBJECTIVETo analyze the efficacy and safety of bicyclol combined with thymosin in treatment of chronic viral hepatitis B (CHB).

METHODSA total of 135 patients with CHB were randomized into experimental group and control group. The patients in the experimental group received bicyclol orally 75 mg daily and thymosin 20 mg intramuscular injection once every 2 days for 24 weeks and those in control group received bicyclol orally 75 mg daily alone for 24 weeks. The levels of serum aminotransferase (ALT/AST), HBV-DNA, HBeAg /antiHBe were observed.

RESULTSCompared with pre-treatment levels, the serum aminotransferase levels decreased significantly in both groups, but there were no statistically significant differences between them. HBeAg negative conversion rate was significantly higher in the experimental group than in the control group (35.3 percent vs.19.4 percent, P less than 0.05). HBV DNA negative conversion rate was significantly higher in the experimental group than in the control group (36.7 percent vs. 20.9 percent, P less than 0.05). No obvious adverse events which were probably related to the drugs were observed in this study.

CONCLUSIONThe combination of bicyclol with thymosin had better effect in treatment of chronic hepatitis B ias compared with bicyvlol alone.

Objective To investigate the prevalence and risk factors of chronic kidney disease (CKD) in adult residents of Shanghai Pudong New Area. Methods A total of 5584 residents aged 20-80 years old were randomly selected from Shanghai Pudong New Area through multistage sampling and interview between April and July 2008. Fasting blood samples and morning urine samples were collected to detect Scr and urinary albumin and creatinine. Urine albumin to creatinine ratio (ACR) and glomerular filtration rate (GFR) was calculated to estimate the renal function. Logistic regression model was used to examine the associations of demographic and lifestyle factors with indicators of kidney damage. Results The age-standardized prevalence of albuminuria, reduced renal function and CKD was 9.9% (male 8.0%, female 12.4%), 1.1% (male 1.3%, female 0.9%) and 11.0%(male 8.8%, female 12.7%), respectively. The prevalence of CKD was higher in female and increased with age. No significant difference in the prevalence was observed between urban and rural areas. Elder, female, high blood pressure, high fasting glucose, dyslipidemia and obesity were associated with CKD independently. Conclusions The prevalence of CKD in Shanghai Pudong New Area is comparable to that previously reported in China or other developed countries, and even higher. CKD is going to be a public health problem and warrants the community-integrated control strategy to prevent the incidence of end-stage renal disease (ESRD) and related complications.

Objective To investigate the added diagnostic value of SPECT/CT imaging over routine planar whole-body bone scintigraphy (WBBS) for bone metastases from lung cancer. Methods One hundred and forty-six patients with lung cancer, confirmed by pathological examination, underwent routine 99Tcm-MDP (1110 MBq) WBBS, followed by SPECT/CT over the regions with indeterminate findings on WBBS. Both WBBS and bone SPECT/CT images were interpreted by two experienced nuclear medicine physicians in consensus as the positive, negative or uncertain bone metastases. The final diagnosis was comfirmed by pathology or clinical follow-up. x2 test was used to compare the differences between the two imaging methods. Results Finally, 45 patients were diagnosed as positive bone metastases and the other 101 as negative. The diagnostic sensitivity of bone SPECT/CT for bone metastases from lung cancer was 93.3%(42/45), singnificantly higher than that of WBBS (64.4%, 29/45) (x2 = 19.944, P＜0.05). The diagnostic accuracy of bone SPECT/CT was 89.7% ( 131/146), much higher than that of WBBS (44.5%,65/146) ( x2 = 69. 598,P ＜ 0.05). The uncertain and incorrect diagnostic rates of bone SPECT/CT and WBBS were 10.3% ( 15/146, raging from 5.3% to 15.2% with 95% confidence interval (CI) ) and 55.5% (81/146, raging from 47. 4% to 63.5% with95% CI), respectively. Conclusion BoneSPECT/CT provides incremental diagnostic value over routine WBBS for bone metastases from lung cancer.

Objective To investigate the additional diagnostic value of 99Tcm-MDP SPECT/CT over conventional SPECT scan in patients with spinal bone malignancy. Methods Fifty-two patients (mean age (56±14) years) with suspicious spinal bone diseases underwent both bone SPECT and SPECT/CT imaging right after 99Tcm-MDP whole-body planar bone scintigraphy. All patients were pathologically diagnosed by either spine operation or trans-spinal biopsy. The images were evaluated by two independent reviewers; inter-reviewer agreement was evaluated using a weighted Kappa score. Each focus of abnormality was recorded using a 4-point diagnostic confidence scale: benign (B), possibly benign (PB), possibly malignant (PM) or malignant (M). Results Accord to the pathological results, 36 patients had bone malignancy (19 with metastatic tumors and 17 with non-metastatic tumors) and 16 had benign lesions. Over SPECT images, two reviewers rated 73.1% (38/52) and 67.3% (35/52) the lesions as the equivocal (PB or PM) respectively. Over SPECT/CT images, they rated only 25.0% (13/52) and 13.5% (7/52) lesions as the equivocal. Inter-reviewer agreement was 63.5% (weighted Kappa score=0.62) for SPECT and 78.9% (weighted Kappa score=0.81) for SPECT/CT. Conclusions Compared with99Tcm-MDP SPECT, 99Tcm-MDP SPECT/CT results in a significant reduction of equivocal diagnoses for the spinal bone malignancy.

OBJECTIVETo report the results of clinical characteristics, enzyme activity determination and mutation analysis of GLB1 gene in a Chinese patient with mucopolysaccharidosis (MPS) type IVB (Morquio B disease).

METHODA 14-year-old Chinese boy with MPS type IVB was firstly diagnosed by blood leucocytes galactosamine-6-sulfate sulfatase (GALNS) and β-galactosidase (GLB1) determination, who was characterized by short stature, multiplex skeletal abnormalities, difficulty in walking. PCR-sequencing analysis was applied to detect the mutations in GLB1 of the patient.

RESULTThe patient was characterized by dwarfism, pectus carinatum, kyphosis, normal intelligence, and no neurologic damage of spasms, linguistic capacity and so on. The patient had normal GALNS enzyme activity and very low GLB1 enzyme activity [5.03 nmol/(h·mg) vs. normal value 118 - 413 nmol/(h·mg) ] in leukocytes. A compound heterozygous missense mutations c.442C > T(p.R148C)/c.1454A > G(p.Y485C) in GLB1 gene were detected in this patient. The mutation p.Y485C is a novel variant. With the method of gene analysis of new variant, the mutation p.Y485C was considered to be a pathogenic mutation.

CONCLUSIONThe MPS IVB patient showed severe multiple skeletal deformities, normal intelligence, no neurologic damage and very low GLB1 enzyme activity, who carries compound heterozygous mutations p.R148C/p.Y485C. The mutation p.Y485C in GLB1 gene may be a novel pathologic mutation of MPS type IVB.
