The quality of traditional Chinese medicines (TCMs) has been mainly evaluated based on chemical ingredients, yet recently more attentions have been paid on biological ingredients, especially for pill-based preparations. It is a key approach to establish a fast, accurate and systematic method of biological ingredient analysis for realization of modernization, industrialization and internationalization of TCMs. The biological ingredient analysis of TCM preparations could be abstracted as the identification of multiple species from a biological mixture. The metagenomic approach based on high-throughput-sequencing (HTS) and big-data-mining has been considered as one of the most effective methods for multiple species analysis of a biological mixture, which would also be helpful for the analysis of biological ingredients in TCMs. Simultaneous identification of diverse species, including the prescribed species, adulterants, toxic species, protected species and even the biological impurities introduced through production process, could be achieved by selecting appropriate DNA biomarkers, as well as applying large-scale sequence comparison and data mining. By this approach, it is prospective to offer an evaluation basis for the effectiveness, safety and legality of TCM preparations.

Doppler echocardiography was performed to evaluate the tricuspid regurgitation in 786 infants and children with heart disease. 3 Doppler methods were used. : The duration of systolic turbulence of tricuspid regurgitation in thr right atrium was evaluated by continuous wave Doppler method, the distance of systolic turbulence within right atrium from the tricuspid plane, by pulsed Doppler method and the retrograde systolic hepatic vein regurgitation, by color Doppler method. The following results were obtained. 1) Incidence of pan systolic tricuspid regurgitation in each disease were as follows. 68% of ECD, 66% of Ebstein's anomaly, 54% of pulmonary atresia, 50% of arrhythmia, 45% of ASD, 38% of TAPVR, 15% of VSD, 26% of TOF, 12% of PDA, 13% of normal children. 2) In about 90% of children with tricuspid regurgitation, hepatic vein regurgitation was detected by color Doppler echocardiography.

A statistical comparison of pulmonary artery and pulmonary venous wedge pressure has been made by the correlation coefficient method in 24 children with various congenital heart disease. None of them had pulmonary hypertension above the normal range. During the systolic phase, pulmonary arterial pressure was 2.02+/-2.64mmHg greater than pulmonary venous wedge pressure with poor correlation(r=0.57). During the diastolic phase, pulmonary venous wedge pressure was 2.08+/-2.47mmHg greater than pulmonary aetery pressure with poor correlation(r=-.63). Mean pulmonary arterial pressure was 0.79+/-1.02mmHg greater than pulmonary venous wedge pressure with good correlation (r=0.96). Therefore, it is concluded that if pulmonary artery is not entered, a pulmonary vein wedge pressure is a useful indication of pulmonary artery mean pressure in selected cases of congenital heart disease.

OBJECTIVETo investigate the prevalence and subtype distribution of human papillomavirus (HPV) infection and its correlation with age among women in Beijing urban area, and provide some epidemiological evidence for the clinical application of HPV vaccines.

METHODSWe collected cervical specimens from 1999 women in the Outpatient Department of our hospital, performed genetyping of HPV-DNA, and analyzed the incidence of HPV infection in different age groups.

RESULTSHPV infection was detected in 502 (25.2%) of the 1999 women patients, with 391 (19.6%) cases of high-risk HPV, which included 326 (83.4%, 326/391) cases of single infection. HPV-16 was the most common type (21.2%, 69/326), followed by HPV-52 (19.3%, 63/326) and HPV-58 (16.0%, 52/326). The prevalence of HPV infection was the highest among the women aged 41 -50 years and the lowest among those over 60 years.

CONCLUSIONThe subtype- and age-specific distribution of HPV infection among women in Beijing urban area shows an obvious heterogeneity, which deserves due consideration in the clinical application of HPV vaccines.
