Objective To analyze the utilization of Chinese medicines in outpatients of our hospital for the rational use of Chinese medicines in clinic. Methods Drug consumption data during 2010-2012 were collected from the hospital information system database,and drug daily dosages(DDDs)and consumption sum were statistically analyzed. Results The amount of Chinese medicines was 33.07%-36.29%of all drugs costs in the outpatients from 2010-2012. From DDDs’top 10 Chinese medicines during 2010-2012, medicine for cardiovascular medications and urinary system had a great percentage, and the doctors used Chinese medicines reasonably. Conclusion The Chinese medicines uses in outpatients of our hospital is generally rational.

Objective To establish the HPLC fingerprints of Tangbikang Granules; To scientifically evaluate and effectively control the quality of Tangbikang Granules; To ensure its production stability. Methods HPLC was performed on the column of Germany Merck RP-18 endcapped (250 mm × 4.6 mm, 5 μm) with mobile phase of acetonitrile-0.1% formic acid water; column temperature was 40 ℃; flow rate was 1.0 mL/min; detection wavelength was 240 nm; volume injection was 20 μL. Fingerprint Similarity Evaluation Software (edition 2004A) of Chinese Pharmacopoeia Commission was used to evaluate the similarity of the 10 batches of Tangbikang Granules, and to analyze the correlations of 9 ingredients in Tangbikang Granules. Results Wogonoside was used as the reference peak, and the common mode for the HPLC fingerprints was set up. The similarities of the 10 batches of Tangbikang Granules were above 0.930, and altogether 25 common peaks in the chromatograms were found, of which 18 peaks were assigned to Chinese materia medica in Tangbikang Granules. Conclusion The method has good separability and is accurate and simple, which can provide references for the quality control of Tangbikang Granules.

In order to develop clinical diagnostic tools for rapid detection of the SARS-CoV (severe acute respiratory syndrome-associated coronavirus) and to identify candidate proteins for vaccine development, the C-terminal portion of the nucleocapsid (NC) gene was amplified using RT-PCR from the SARS-CoV genome, cloned into a yeast expression vector (pEGH), and expressed as a glutathione S-transferase (GST) and Hisx6 double-tagged fusion protein under the control of an inducible promoter. Western analysis on the purified protein confirmed the expression and purification of the NC fusion proteins from yeast. To determine its antigenicity, the fusion protein was challenged with serum samples from SARS patients and normal controls. The NC fusion protein demonstrated high antigenicity with high specificity, and therefore, it should have great potential in designing clinical diagnostic tools and provide useful information for vaccine development.

To unravel the genetic mechanisms of disease and physiological traits, it requires comprehensive sequencing analysis of large sample size in Chinese populations. Here, we report the primary results of the Chinese Academy of Sciences Precision Medicine Initiative (CASPMI) project launched by the Chinese Academy of Sciences, including the de novo assembly of a northern Han reference genome (NH1.0) and whole genome analyses of 597 healthy people coming from most areas in China. Given the two existing reference genomes for Han Chinese (YH and HX1) were both from the south, we constructed NH1.0, a new reference genome from a northern individual, by combining the sequencing strategies of PacBio, 10× Genomics, and Bionano mapping. Using this integrated approach, we obtained an N50 scaffold size of 46.63 Mb for the NH1.0 genome and performed a comparative genome analysis of NH1.0 with YH and HX1. In order to generate a genomic variation map of Chinese populations, we performed the whole-genome sequencing of 597 participants and identified 24.85 million (M) single nucleotide variants (SNVs), 3.85 M small indels, and 106,382 structural variations. In the association analysis with collected phenotypes, we found that the T allele of rs1549293 in KAT8 significantly correlated with the waist circumference in northern Han males. Moreover, significant genetic diversity in MTHFR, TCN2, FADS1, and FADS2, which associate with circulating folate, vitamin B12, or lipid metabolism, was observed between northerners and southerners. Especially, for the homocysteine-increasing allele of rs1801133 (MTHFR 677T), we hypothesize that there exists a "comfort" zone for a high frequency of 677T between latitudes of 35-45 degree North. Taken together, our results provide a high-quality northern Han reference genome and novel population-specific data sets of genetic variants for use in the personalized and precision medicine.
