Objective To introduce the techniques and clinical application of coronary arterial calcification measurements by using the multi-slice CT (MSCT). Methods The recent literature on the coronary artery calcium scoring with MSCT were reviewed. The data acquisition, image reconstruction, quantification methods in assessment of calcium and usefulness of calcium scoring in coronary artery disease were investigated. Results MSCT with nearly isotropic volumetric imaging data, subsecond rotation and retrospective electrocardiographic gating could provide better input data for quantification of coronary arterial calcium volume. Conclusion MSCT allows more precise and repeated measurement of coronary arterial calcification with low interexamination variability.

AIM: To investigate the quality of life in adults with strabismus and evaluate the improvement in quality of life after treatment.
METHODS: In this prospective study, forty-five adults with a diagnosis of strabismus conform to the inclusion and exclusion standard were selected in our hospital from October 2013 to May 2014, as experimental group and 45 normal adults were enrolled as control group. A Chinese Adult Strabismus-20 questionnaire was used to evaluate the differences of quality of life between patients with strabismus and normal adults, and to evaluate the differences of quality of life in patients with strabismus preoperative and 6mo postoperative.
RESULTS:The scores of quality of life in adult patients with strabismus preoperative and 6mo postoperative were statistically significant lower than those of normal adults (P< 0. 01). In 6mo postoperative, the scores of quality of life statistically significant increased than preoperative ( P<0. 01).
CONCLUSION: Strabismus can decrease the quality of life in psychosocial and visual functional for adults and the surgical treatment can improve quality of life in patients with strabismus.

Sensory, chemical, microbiological quality and bacterial flora on fresh Pseudosciaena crocea were qualitatively and quantitatively investigated. The results showed that total viable counts and total volatile basic nitrogen reached 5. 51?0. 25Log10cfu/g, 7. 84?2. 25mg/100g respectively. 279 strains of bacteria were isolated and 84.2% of them were gram negative bacteria, a small percentages of gram positive bacteria were detected (6. 1% ) . The predominant bacterial floras were composed of Enterobacteriaceae (14. 7% ), Aeromonas spp. (12. 5% ), Acinetobacter spp. (11. 5% ) and Moraxella spp. (11. 1% ) . A few percent of Pseudomonas spp. , Stenotrophomonas maltophilia and other bacteria were also found. The high number of Enterobacteriaceae showed that bacterial contamination on Pseudosciaena crocea, was mainly from cultural water field and polluted seriously by non-borne bacteria, and it should be paid attention to.

ObjectiveTo examine the prognostic value of 99mTC-MIBI single-photon emission computed tomography (SPECT) in patients with suspected or diagnosed coronary artery disease (CAD).Methods116 patients with suspected or diagnosed CAD were examined with 99m TC-MIBI SPECT exercise and rest myocardial imagings, and followed by investigation of cardiac events.Results Follow-up information was complete in 106 patients. Over an average follow-up of 25±8 months, cardiac events occurred in 11 patients. Univariate analyses showed that age, old myocardial infarction, exercise peak heart rate, the change in heart rate from rest to exercise peak, exercise peak systolic blood pressure, the change in systolic blood pressure from rest to exercise peak, abnormal myocardial imaging, the number of myocardial perfusion defect and ischemic volume rate (IVR) were the effective predictors of subsequent cardiac events. Multivariate stepwise Logistic regression analyses revealed that the size of IVR was the only variable with independent predictive value for occurrence of subsequent cardiac events. IVR more than 25% was associated with a significantly increased frequency of subsequent cardiac events (relative risk ratio was 5.9, P<0.005). IVR less than 25% or even normal myocardial perfusion imaging was associated with a very low-risk of cardiac event and a very good prognosis.Conclusion 99mTC-MIBI SPECT myocardial imaging is the most effective noninvasive technique that predicted the occurrence of cardiac event in patients with suspected or diagnosed CAD. According to the size of IVR, high-risk and low-risk patients can be effectively identified.

Objective To survey and analyze characteristics of brucellosis epidemic in Weinan city of Shaanxi province for the purpose of setting up prevention and control measures for the disease. Methods According to "The Executing Plan for the Work of Surveying Brucellosis Disease in Shaanxi Province", 35 villages(towns) of designated monitoring locations and 24 villages (towns) of randomized monitoring locations in five countries of Weinan were chosen to survey brucellosis disease. The five countries were Chengcheng, Dali, Heyang, Tongguan and Hancheng. High risk populations with a history of contacting livestock and livestock products aged between 7 and 60 underwent clinical and serology examination[rose bengal plate agglutination test(RBPT) and standard tube agglutination test(SAT)]. All manipulation methods and judging standards were in accord with the "Diagnostic Standard for Brucellosis" (WS 269-2007). Results In the designated monitoring location, a total of 8664 people at high risk were investigated, among whom 1407 people were tested by RBPT test and 27 people were positive,the positive rate was 1.92%(27/1407); 27 people were tested by SAT test and 27 people were positive, the positive rate was 100% (27/27); 25 people were diagnosed and the diagnosis rate was 92.59%(25/27). In the randomized monitoring location, a total of 3464 people at high risk were investigated, among whom 411 people were tested by RBPT test and 3 people were positive, the positive rate was 0.73%(3/411 ), 3 people were tested by SAT test which were all positive and made a definite diagnosis. Twenty-eight new cases were made a definite diagnosis and its incidence was 2.06 in a hundred thousand(28/1 361 618). Conclusions The infection of human brucellosis in Weinan city stays at higher level. The governments should increase input for the monitoring,investigating and disinfecting to prevent the disease from increasing and outspreading.

Ten dimeric phthalide racemates (1-10) were isolated from an aqueous extract of the Angelica sinensis root head (Guitou) by separation techniques of column chromatography over macroporous adsorbent resin, MCI resin, silica gel, and Sephadex LH-20, together with preparative thin-layer chromatography and reversed phase HPLC. The racemates were further separated into (+)-/(-)-1-(+)-/(-)-10 with chiral HPLC. Their structures including absolute configurations were elucidated by comprehensive analysis of spectroscopic data, combined with electronic circular dichroism (ECD) and NMR calculations as well as single crystal X-ray diffractions. Compounds (+)-/(-)-1-(+)-/(-)-10 are either new structure or new natural product, named (+)-/(-)-angelidipthalidic acids A-H [(+)-/(-)-1-(+)-/(-)-8] and (+)-/(-)-angelidipthalidols A and B [(+)-/(-)-9 and (+)-/(-)-10], respectively. Meanwhile, dimeric phthalide mono- and bis-lactone derivatives with 3.3′a,8.6′- and 3.6′,8.3′a-coupling patterns as well as determination of their relative configurations are discussed.
