OBJECTIVETo study the prevalence of asthma and its correlated factors in Zaozhuang area in 2003, to provide a basic consideration for prevention/treatment and control policy.
METHODS6 points were selected by stratified-clusterd-random sampling with a total of 16,725 persons expected, but only 10,610 subjects investigated.
RESULTSIn this survey, 128 asthma cases were identified with a overall prevalence of 1.21%. The prevalence for children was 2.02%, and for adult was 0.90% with the former significantly higher then the latter (chi(2) = 21.39, P < 0.01). Rates for male and female were 1.08%, 1.32% with a ratio of 1:1.22. For 77.97% of children with asthma. The initiative age of asthma was before 7 years old among children while among 36.23% of the adults, it was before 15 years of age. Correlation analysis showed that upper respiratory tract infection (OR = 17.81, 95% CI: 12.25-25.89), cold air exposure (OR = 3.43, 95% CI: 2.41-4.90), stimulation through cooking and by harmful gases (OR = 2.56, 95% CI: 1.80-3.63), allergic materials (OR = 2.74, 95% CI: 1.80-4.17) were main inducing factors. 65.63% of the asthma cases having had history of allergic disease while 25.78% having had family history with the OR of allergic history and family history as 21.69 vs. 73.96.
CONCLUSIONThe epidemic status of bronchial asthma was serious, with an assumption that asthma cases might have reached the number of 43 thousand in Zaozhuang area.

OBJECTIVETo evaluate the usefulness of multi-slice spiral CT (MSCT) in the post-operative assessment of cochlear implanted electrode.
METHODSTwenty-three cochlear implant recipients were enrolled in this study. All patients were examined with a SOMATOM Sensation 16-slice CT scanner (Siemens) using the following parameters: 120 kV, 100 mAs, 0. 75 mm collimation, 1 mm reconstruction slice thickness and increment, a pitch factor of 1, and a FOV of 100 mm. The axial images of interested ears were reconstructed with 0.1 mm increment and a FOV of 50 mm, and then volume rendering technique (VRT) reconstruction were done on the work station.
RESULTSThe electrode arrays were detected on axial CT images. Both inner ear and electrode array could be displayed on one image simultaneously. VRT provided an intuitionistic view of the relationship between electrode array and cochlea VRT showed the number of the electrode array in 20 patients implanted with Combi 40 + standard electrode array and demonstrated the shape, position, and insertion depth. The electrode array number determined by VRT was in accordance with the surgical findings in 18 patients, and was underestimated in two patients. In 3 patients with Combi 40 + compressed electrode array, only 4 to 5 electrodes arrays were clearly identified and others were not observed.
CONCLUSIONMSCT with VRT can provide useful three-dimensional information of the electrode array and indicate the exact relationship between electrode array and cochlea.

OBJECTIVETo investigate the mutation characteristics of spastin gene in Chinese patients with hereditary spastic paraplegia (HSP) and thus provide a basis for the gene diagnosis of HSP.
METHODSMutation of spastin gene was screened by polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) combined with DNA direct sequencing in 31 unrelated affected HSP individuals in China, of whom 22 were from autosomal dominant families and 9 were sporadic HSP patients. Co-segregation analysis was carried out after the finding of abnormal SSCP bands.
RESULTSSix cases were found to have abnormal SCP bands, and among them, two missense mutations (T1258A, A1293G in exon 8) and one deletion mutation (1667delACT or 1668delCTA or 1669delTAC in exon 14) were found and all of them were not reported previously. They were all co-segregated with the disease and were localized within the functional domain of spastin gene. Besides, T1258A was seen in two unrelated families.
CONCLUSIONThe mutation rate (18.2%) in autosomal dominant HSP in Chinese patients is comparatively low. Point mutation is the major mutation type and exon 8 may be the mutation hot spot.

OBJECTIVETo establish the spectra of metabolites that coued be employed in identification of oral pathogenic bacteria, and try to find a convenient and rapid way to discriminate oral microorganisms.
METHODSSuspensions of Streptococcus mutans ATCC 25175, Streptococcus sanguis ATCC 10556 and Lactobacillus acidophilus ATCC 4356 with same density were preparecd and cultured respectively at improved TPY liquid culture medium. The growth quantity were measured periodically by a turbidimeter. And the growth curves of the inoculated bacteria were completed. The culture solutions in stationary phase of the three bacteria were tested with 1H-nuclear magnetic resonance (1H-NMR) spectroscopy respectively. The data of 1H-NMR spectroscopy results were analyzed by principal components analysis (PCA).
RESULTSThe PCA showed the obvious clustering phenomena and the points of three group differentially centralized to three clusters. Therefore, the NMR-based metabonomics profiles could discriminate the three different kinds of bacteria.
CONCLUSIONThe metabonomics is a promising new technology for developing to a rapid discrimination method of oral pathogenic bacteria.

OBJECTIVETo analyses the clinical characteristics and electrophysiological finding of 106 patients with auditory neuropathy (AN). Investigate the differential curve type of pure tone audiogram and the abnormal ABR.
METHODSReview the history of patients, pure tone audiometry, middle ear acoustic reflexes, auditory brainstem response, distortion product otoacoustic emission and radiologic imaging studies of the brain of 106 patients with AN during December 2001 to May 2007 in retrospect.
RESULTSThe 106 patients with AN were of both genders. The age were between 11-37 years old, and the average age was 17.5 years old. The most patients were adolescence (70.8%). Twelve cases of the 106 patients had evidence of other peripheral neuropathy in addition to hearing loss. Another 94 patients were idiopathic origins. The pure tone audiogram showed a minimal to moderate sensorineural hearing loss at low frequencies 0.5 kHz and 0.25 kHz in 209 ears (98.6%). The average hearing threshold (WHO 1997) in 23.2% of disordered ears at less than 25 dB in the "normal" range. Auditory brainstem response could not be recorded in 124 ears (58.5%) at maximum stimulus. The other 88 ears showed 1 or 2 wave, but the wave were small. There were 23 patients which one side ear ABR was 1 or 2 small waves presented, but the contralateral side were all waves absent. In 3 cases of AN with other peripheral neuropathy which ABR were both ears 1 or 2 small wave ear recorded. However, 1 patient in our sample could not be detected distortion product otoacoustic emission at 3-6 kHz (left ear) and 5-6 kHz (right ear).
CONCLUSIONSAN was not rare in adolescence. The average hearing threshold for AN should be discussed.

The STandards for Reporting Interventions in Clinical Trials Of Moxibustion (STRICTOM), in the form of a checklist and descriptions of checklist items, were designed to improve reporting of moxibustion trials, and thereby facilitating their interpretation and replication. The STRICTOM checklist included 7 items and 16 sub-items. These set out reporting guidelines for the moxibustion rationale, details of moxibustion, treatment regimen, other components of treatment, treatment provider background, control and comparator interventions, and precaution measures. In addition, there were descriptions of each item and examples of good reporting. It is intended that the STRICTOM can be used in conjunction with the main CONSORT Statement, extensions for nonpharmacologic treatment and pragmatic trials, and thereby raise the quality of reporting of clinical trials of moxibustion. Further comments will be solicited from the experts of the CONSORT Group, the STRICTA Group, acupuncture and moxibustion societies, and clinical trial authors for optimizing the STRICTOM.

OBJECTIVETo study the distribution of ScrF1 restriction polymorphism in intron 2 of the 3-hydroxy-3-methylglutaryl coenzyme A(HMG-CoA) reductase gene in Chinese Han population and the association of the polymorphism with coronary heart disease(CHD).
METHODSHMG-CoA reductase genotyping was performed using polymerase chain reaction-restriction fragment polymorphism.
RESULTSHMG-CoA reductase allelic frequencies of A, a were 0.519, 0.481; 0.440, 0.560 in CHD group and control group respectively. There was no significant difference in frequencies of allele and genotype in ScrF1 polymorphism between CHD group and control group(P>0.05). However, the levels of plasma very low density lipoprotein (VLDL) and TG in CHD patients with AA genotype were higher than those in CHD patients with other genotypes(P<0.05). The frequencies of A, a alleles at ScrF1 polymorphic site were significantly different from those reported in European Caucasians (0.44 vs 0.55, 0.56 vs 0.45, P<0.05).
CONCLUSIONNo direct association was found between the ScrF1 polymorphism and CHD, but there is a significant correlation between the AA genotype of the HMG-CoA reductase gene and the levels of plasma VLDL and TG in CHD group.

OBJECTIVETo compare and analyze the MRI features of different renal cell carcinoma (RCC) subtypes.
METHODSThe MR images of 81 surgically and pathologically confirmed renal cell carcinomas from 79 patients were reviewed retrospectively. The MR imaging features of lesions in plain scan, the degree and patterns of lesion enhancement (homogeneous, heterogeneous, peripheral), and tumor spreading patterns were analyzed. In order to evaluate the diagnostic validity of differentiating RCC subtypes using signal enhancement, receiver operating characteristic curves (ROC) were generated. The cutoff value of post-contrast signal intensity to noise ratios (SNR) of the tumor parenchyma were also generated in order to differentiate clear cell RCC from other subtypes.
RESULTSOf the 81 lesions, 58 were clear cell carcinomas, 10 chromophobe cell carcinomas, 8 papillary cell carcinomas, and 5 unclassified RCC. All the chromophobe cell subtype tumors showed a homogeneous density (P < 0.05). The clear cell subtype tumors were likely heterogenous, and also showed heterogenous enhancement with mixed signal than other subtypes (P < 0.05). The cutoff value of SNR, which was used to differentiate clear cell subtype from the other subtypes, were 616 (corticomedullary phase), 579 (nephrographic phase) and 278 (excretory phase), retrospectively. The nephrographic phase is the most appropriate for differentiation, with a sensitivity of 62.1%, specificity of 91.3%, positive predictive value of 94.7%, negative predictive value of 48.8% and an accuracy value of 70.3%. No significant difference was found in tumor spreading patterns among all subtypes of RCC.
CONCLUSIONMR imaging features, particularly tumor heterogeneity and degree of enhancement are useful in differentiation of the renal cell carcinoma subtypes, and in choosing an individualized therapy.
