Evidence of the pharmacological activity of traditional Chinese medicine (TCM) provides the basis for clinical prescription. Study of the classification of Chinese medicines according to these activities is key to understanding the general active tendencies of medicinal prescriptions, exploring their material basis, investigating their properties and searching for their alternatives. Taking the herbal classic Shennong's Materia Medica Classic (Shennong Bencao Jing) for the data source, this paper studied the classification of Chinese medicines based on semi-supervised incremental clustering algorithm using "micro-cluster" concept in order to investigate the complex similarity among Chinese medicines. The results showed that 253 Chinese medicines were reasonably classified into 14 types, such as invigoration, clearing heat, diuresis, dredging blockages in the channels, treating gynecological conditions and treating strange diseases caused by ghosts. The results also showed that the other 112 Chinese medicines were classified into 112 individual types and the same high similarity to different known types was the main reason for this. The semi-supervised incremental clustering algorithm employed in the study had a high quality and a good development for clustering which is suitable for classification of Chinese medicines. This study illustrated the diversity of Chinese medicines and their complex similarities, thus aiming to provide innovative ideas and methods for related research.

Objective To investigate the nutritional management level of Department of Clinical Nutrition in elderly inpatients through analyzing the actual hospital dietary intakes in elderly inpatients in Peking Union Medical College Hospital from 2013-2015.Methods Using continuous sampling, the nutrients contents and the eating rates of hospital meals ordered by the elderly inpatients on the 1st, 15th, 29th of every month from May 2013 to October 2015 were selected.The intake levels of energy, protein, calcium, vitamin A, vitamin B1 , and vitamin C were calculated and compared with the Chinese dietary reference intakes (DRIs).The nutritional in-take differences between diabetes diet and the basic hospital diet were also compared.Results A total of 90 days of hospital dietary data from 8 402 elderly inpatients were included in the study.The average eating rate was (50.1 ±4.2)%, which was lower than the general eating rate of the hospital [ (59.0 ±4.0)%, P<0.001]. Only protein intake from hospital diet reached the requirement target [male (103.1 ±47.3)%, femal (98.3 ± 33.8)%].Individual compliance rates were 63.2%and 59.8%, respectively, while the other kinds of nutrients were lower.The compliance rates of energy [ (73.3 ±26.3)%vs.(62.1 ±38.2)%, P<0.001] and ma-jor nutrient intake [ protein: ( 119.1 ±41.2 )% vs.( 93.3 ±65.1 )%, P <0.001; calcium: ( 55.5 ± 26.7)% vs.(34.3 ±34.2)%, P <0.001; vitamin A: (75.2 ±48.3)% vs.(57.4 ±97.1)%, P<0.001;vitamin B1:(76.4 ±38.2)%vs.(52.1 ±46.6)%, P<0.001;vitamin C:(92.2 ±51.4)%vs. (49.3 ±55.0)%, P<0.001) in diabetes diet group were significantly higher than those in the basic hospi-tal diet group.Conclusions The nutritional intakes from hospital diets may not meet the nutritional require-ments based on DRIs in elderly inpatients.Medical diet designed by physicians and dietitians should be ex-panded to improve the nutritional management level for these patients.

Objective To investigate the value of prospectively electrocardiogram (ECG)-triggered high-pitch coronary computed tomography angiography at 70 kV and 30 mL contrast medium with Stellar detector dual-source CT.Methods 60 patients with the BMI<24.9 kg/m2 were randomized into two groups:Group A (30 cases)with the tube voltage of 70 kV and 30 mL contrast medi-um.Group B (30 cases)with the tube voltage of 100 kV and 50 mL contrast medium.All the patients were performed with a Stellar detector dual-source CT using a prospectively ECG triggered high-pitch spiral technique.The images of Group A were reconstructed with SAFIRE technique,while Group B were with FBP technique.The objective image quality includes CT attenuation,SNR, CNR.And radiation dose was also calculated.The subjective was evaluated by 4-scale point.Independent sample t test was used.Re-sults There was no difference for subjective image quality between the groups,A:(3.38±0.942),B:(3.50±0.682),(t=-0.562, P >0.05).The CT attenuation of the 70 kV group were higher than that of the 100 kV group for all the segments(P <0.01).The SNR and the CNR have no statistically significant difference between the groups (P >0.05).Compared with the 100 kV group,the radiation dose of the 70 kV group was reduced by 76.5% (A:0.19±0.023 mSv,B:0.81±0.101 mSv,P <0.01).Conclusion Using 70 kV with 30 mL contrast medium in Stellar detector dual-source CT coronary angiography for the patients with a normal BMI could obtain qualified diagnostic image with low radiation dose and contrast medium.
