Objective To assess the quality of iodized salt and investigate the urinary iodine level of pupils and women after implementation of universal salt iodization in Shijiazhuang city. Methods Between 2004 and 2008, nine salt samples were randomly collected from wholesale enterprises of 5 different directions of east,south, west, north and center in Shijiazhuang city every month. Meanwhile, eight salt samples, four urine samples of women, were randomly collected in each of the 8 households of 210 villages selected from 23 counties. Between 2004 and 2008, twenty urine samples of 8 - 10 year old pupils were collected in each of 160 schools from the 23 counties. Direct titration method was used for salt iodine determination, iodine concentration in urine was detected by the method of ammonium persulfate digestion-As3+-Ce4 + catalytic spectrophotometry. Results At wholesale level, the qualified rate of iodized salt was above 99%. At household level, the consuming rate of iodized salt was above 95%, and the rate of consuming non-iodized salt was less than 5%. The rate of qualified iodized salt was above 90% in every year except 2004(87.10%), and the rate of consuming qualified iodized salt was above 90% in those years except 2004(83.08%). Urinary median iodine level of both the pupils and the women was higher than 100 μg/L, and the rate of urinary iodine level that less than 50 μg/L was below 10%. Conclusions The quality assessment of iodized salt from wholesale companies and related indices of urinary iodine level of pupils, women and household iodized salt have already reached the national standard for eliminating iodine deficiency disorders.

ObjectiveTo study the clinical features, arterial involvement, therapeutic strategies and outcomes of Takayasu arteritis (TA). MethodsThe clinical symptoms, arterial images, inflammatory parameters and follow-up information of 173 patients with TA were retrospectively studied. Comparisons between groups were performed by t-test. ResultsThere were 136 female and 37 male patients in this study. The mean age at onset was(26±11 ) years. Hypertension, pulse deficit or asymmetrical pulse, and fever were present in 46.6％, 41.1％, 28.7％ of patients, respectively. The distribution of arterial involvement were 64.7％in aorta, 9.8％ in pulmonary artery, 19.1％ in innominate artery, 65.9％ in common carotid arteries, 65.3％in the subclavian artery, 36.2％ in the renal artery, 12.1％ in the vertebral artery, and 5.8％ in coeliac axis.Elevated erythrocyte sedimentation rate(ESR) was found in 61.0％ patients. Active tuberculosis or history of tuberculosis was implicated in 45 patients(26.0％). Ten patients(5.8％) were hepatitis B virus carriers.Among 105 followed-up patients, 98 patients(94.2％) achieved persistent remission, 17 patients relapsed when corticosteroids were tapered. ConclusionCorticosteroids combined with or steroid alone, supplemented with endovascular intervention procedures or surgical bypass procedures when necessary, can effectively control the clinical symptoms and inflammatory parameters and improve the quality of life of patients.

70 bpm during scan),the proportion of segments that could not be assessed because of motion artifact were 0.1%(1/759),1.1%(7/649),2.5% (10/407),42.6%(103/242),and 75.5%(108/143),respectively.With conventional selective coronary angiography as the golden standard,the sensitivity,specificity,positive and negative prediction values to detect≥50% stenotic lesions in the assessable segments were 79.2%,96.0%,83.8%,and 94.6%,respectively.There was a significant correlation between the number of segments per patient not assessable because of motion artifact and heart rate during the scan(r=0.655,P=0.000).Conclusion MSCT is capable of achieving high accuracy for detection of coronary artery stenosis,and is a reliable technique to diagnose coronary artery disease.

Objective To observe dopamine transporter (DAT) binding capacity using 99Tcm-TRODAT-1 in drug-naive patients with Tourette's syndrome (TS) on SPECT imaging, and explore possible correlations between 99Tcm-TRODAT-1 uptake ratio and TS patient's age, disease duration, and tic severity.Methods Eighteen drug-naive TS patients, male 14, female 4, as well as 8 age- and gender-matched healthy subjects were recruited. Brain SPECT imaging was performed 2. 5 h after intravenous injection of 11.1 - 14.8 MBq/kg 99Tcm-TRODAT-1. ROI was drawn on the striatum including its sub-regions of caudate and putamen, with cerebellum as the background. Striatum/cerebellum ratio was calculated. Comparisons of the ratios between TS patients and controls were carried out by independent-sample t-test. Pearson correlation analysis was performed between DAT uptake ratios of striatum and patients' age, disease duration, tic severity. Results Compared with the control, higher symmetrically striatum uptake of 99Tcm-TRODAT-1 in TS patients was observed (2.17±0.23 vs 1.87±0.24, t =2.957, P＜0.05). Age (r= -0.320, P＞0.05)and tic severity(r = 0. 345, P ＞ 0.05) scores were not significantly correlated with specific uptake ratios measured in the striatum. But there was significant negative correlation between disease duration and the specific uptake ratios (r = - 0. 483, P ＜ 0. 05). Conclusions 99 Tcm-TRODAT-1 SPECT imaging may play an adjuvant role for initial evaluation of untreated TS.

Objective To evaluate the clinical application of serum CYFRA21-1 detection during the diagnosis of lung cancer. Methods Serum level of CYFRA21-1 in 196 patients with lung cancer and 39 healthy controls were determined by the Elctro-chemiluminescence Immuno-assay ( ECLIA) , respectively. Results Serum level of CYFRA21 -1 ( range from 0. 30 μgg/L to 500.00 μg/L) in patients with lung cancer were significantly higher than those in the healthy control ( range from 0. 27 μg/L to 3. 29 μg/L,Z = -4. 65,P < 0.01). ROC analysis of diagnosis efficiency showed that the area under curve ( AUC) was 0. 735 (P < 0. 001 ). The confidence interval of 95% was from 0. 663 to 0. 807. Positive detection rate of CYFRA21-1 was 48. 8% (39/80) in squamous,31.7% (20/63) in adenocarcinoma and 22. 6% (12/53) in small cell lung cancer (SCLC) respectively, as well as total positive rate was 36. 2% (71/196). Stepwise regression analysis showed that serum level of CYFRA21-1 had a linear correlation with the squamous and the metastasis to liver or bone (r =0. 505 ,P <0. 05). Conclusions Serum level of CYFRA21-1 increases the diagnostic sensitivity, which is helpful for determining histological types, monitoring the metastasis of liver and bone, and evaluating the treatment response in patients with lung cancer.

To evaluate the cohort study in Chinese medicine research, especially in acupuncture study field. This paper introduced the concepts, methods and applications of cohort study; furthermore, it introduced the applications and progress of cohort study in clinical Chinese medicine research at present. In China, cohort study has been mainly used in Chinese medicine research focusing on tumors, any researches using cohort study in acupuncture were not retrieved. Contrarily, the cohort study has been used earlier and advocated to apply in abroad acupuncture research. As one of methods in classic epidemiological observational studies, cohort study is fit to evaluate clinical researches of Chinese medicine and acu-moxibustion, so it is worthy of being promoted in applications.
