Objective To search for evidence of diagnosis of pulmonary embolism for guiding clinical practice.Methods We searched PubMed(1970~2005-10)and CBM(1992~2005-10)in Oct.2005 to identify system reviews(SR)and cross-sectional study(CSS)about the diagnosis of pulmonary embolism.Results Sixteen SR and 9 CSS were identified in PubMed,none in CBM.Pulmonary arteriography was the gold standard in the diagnosis of pulmonary embolism.Our result showed that computed tomography,ventilation-perfusion scanning and doppler ultrasound were useful in the diagnosis of pulmonary embolism combind with clinical judgment.Multidetector CT might be another gold standard in the diagnosis of pulmonary embolism.A negative result on quantitative rapid ELISA of D-dimer could exclude the diagnosis of pulmonary embolism.Conclusion Diagnostic tests combind with clinical judgment are useful for diagnosing or excluding pulmonary embolism.

The HLA DQA1 genes of 40 IDDM patients (including 8 cases with onset of diabetes before 14 years of age, 19 between 15-30 years and 13 after 31 years) and 51 healthy controls were studied by using for allele specific oligonucleotide probes. All of our research subjects are of Southern Chinese origin. The results showed that the HLA DQA1 52Arg(+) associated IDDM susceptibility is significantly higher in the group younger than 14 years of age (P

AIM:To evaluate the poor vision condition and analyze the myopia etiological factor in primary school He'xi district of Sanya.
METHODS: A cohort of 1 218 subjects were recruited randomly from grade 1~6 of two primary schools. Visual activity test, dioptroscopy and risk factor questionnaire were evaluated.
RESULTS: The prevalence of poor vision was 29. 55%. The incidence of myopia increased with grade, and was significantly higher in girls than that in boys. The outdoor activity time of myopic pupil ( 7. 25 ± 5. 35h/wk ) was significantly lower than emmetropic pupil (11. 86±6. 65h/wk) ( P < 0. 05 ). The usage of electronic product ( TV, computater and cell phone) time of myopic pupil (13. 36±8. 35h/wk) was significantly higher than emmetropic pupil (7. 75±5. 83h/wk) (P<0. 05).
CONCLUSION: The increase of myopia incidence is closely related with sparing outdoor activity and excess usage of electronic product.

We present an algorithm for numerical solution of transport equation in diffusive regimes, in which the transport equation is nearly singular and its solution becomes a solution of a diffusion equation. This algorithm, which is based on the Least-squares FEM in combination with a scaling transformation, presents a good approximation of a diffusion operator in diffusive regimes and guarantees an accurate discrete solution. The numerical experiments in 2D and 3D case are given, and the numerical results show that this algorithm is correct and efficient.

Trans-cinnamaldehyde, the main component of volatile oil from cassia twig or Cinnamomum cassia, which is a traditional Chinese herbal medicine. Trans-cinnamaldehyde is a kind olefine aldehyde of organic compounds and has many pharmacological properties, such as anti-inflammatory, anti-tumor, anti-bacterial, antidiabetic, anti-obesity, and neuroprotection etc. The compound has preventive and therapeutic effects on the nervous system, cardiovascular, cancer, diabetes and other diseases. Trans-cinnamaldehyde, as a preventive care of nature medicine, has great clinical and market potential. This paper gives a review about the pharmacological effects and mechanism of trans-cinnamaldehyde researched in the latest five years. We hope to provide some basic information for further research on trans-cinnamaldehyde.

AIM: To explore the effects of prostaglandi n I 2 (PGI 2) on mesenteric microcirculation and hemorheology during renal isch emia/reperfusion (IR) injury. METHODS: 36 rabbits were randomly distributed into the sham oper ated group (sham group), renal ischemia/reperfusion injury group (IR group) and PGI 2+IR group(PGI 2 group). IR group received clamping for 60 min follow ed by 120 min of reperfusion. A microcircular microscope image analysis system w as used to study the changes of mesenteric microcirculation and hemorheology at 60 min of ischemia and 120 min of reperfusion, respectively, while the blood sa mples were obtained for the measurement of hemorheological indexes. RESULTS: ① In IR group during the period of renal IR, the numb er of adhesive leukocytes and microthrombus, hemorrhage and hemorheological ind exes such as blood viscosity, plasma viscosity, blood reduction viscosity, he matocrit, erythrocyte aggregation index, erythrocyte sedimentation rate, eryt hrocyte sedimentation rate K and plasma fibrinogen were significantly higher, w hile microvascular diameters, blood flow velocity and erythrocyte deformation i ndex were significantly lower compared with sham group (P0.05). CONCLUSIONS: PGI 2 ameliorates the disturbance of mesenteric microcirculation and hemorheology caused by renal IR injury with the best effect at 10 ng?kg -1?min -1.

Objective To explore the association of dietary behavior of children with Tourette syndrome (TS) and tic symptoms.Methods 207 TS children and their 264 corresponding controls,who visited our hospital during the period of November 2008 to October 2010,were investigated with children' s dietary behavior questionnaire,under the guidance of professional staff,and the TS tic symptom severity was also evaluated according to The Yale Global Tic Severity Scale (YGTSS).Kruskal-Wallis H rank-sum test was applied for univariate analysis and multinominal logistic regression for further multivariate analysis,with values of odds ratio (OR) and population attributable risk (PAR) obtained to demonstrate the relation strength between dietary behavior and tic symptom severity.Results Results of univariate analysis showed that western fast meal,barbecues,cream food,cold food,and spicy food were related to TS tic symptom severity (P<0.05).Results of multivariate analysis demonstrated that western fast meal,fruits and vegetables,cream food and spicy food were risk factors for mild TS compared with control group,with OR and 95% CI of 3.282 (1.922,5.064),2.239 (1.298,3.861),2.341 (1.355,4.046),2.118 (1.327,3.380) and their corresponding PAR of 0.306,0.464,0.169,0.250 respectively.As to moderate and severe TS,the risk factors included western fast meal,fruits and vegetables,and spicy food,with their respective OR and 95% CI of 2.581 (1.322,5.038),2.364 (1.166,4.795),1.822 (1.014,2.272) and PAR of 0.234,0.487,0.197.Conclusion Dietary behavior,especially western fast meal,fruits and vegetables,cream food and spicy food,are considered to be associated with TS tic symptom severity.Therefore it' s obligatory to rectify undesirable dietary behaviors for TS children.
