A new method for analysis of cobalt phthalocyamine sulfonates(CoSPC) by thin layer chromatography/flame ionization detector (TCL/FID) was investigated. Different compounds in CoSPC can be separated by TLC, and structure can be further identified by matrix-assisted laser desorption/ionization-time-of-flight-muss spectrometry (MALDI-TOF-MS). Experimental results indicated that commercial CoSPC has three compounds, cobalt phthalocyanine (CoPC) mono-sulfonates with two isomers, CoPC di-sulfonates with five isomers and CoPC- tri-suflonates, TCL/FID could be used to determine the amount of different compounds. This method is featured by its ease operation, quick response, good separation and satisfactory results.

Objective To study molecular adsorbent recycling system (MARS) in the treatment of patients with acute liver failure waiting for liver transplantation. Methods The effects of MARS artificial liver treatments in 16 cases were reviewed. Results There was a remarkable improvement in clinical symptoms and physical signs after MARS treatment, including significant decrease in prothrombin time, total bile acid, level of alanine aminotransferase, aspartate aminotransferase, creatinine, and blood ammonia (P<0.05=;There was no statistical change in NO,TNF-α and IL-10(P>0.05).Sequential organ failure assessment(SOFA)score decreased from 9.91±1.09 to 6.64±1.76 and Glascow coma score increased from 7.29±2.06 to 13.26±2.14.Fourteen patients were tided over to liver transplantation among them 13 patients survived and were successfully discharged from the hospital. The survival rate was 89.5%.Conclusion MARS is a safe and effective assistant device in bridging acute liver failure patients to liver transplantation.

Gratifying progress has taken place both in clinical studies and basic research of IM on CHD during 2013. We got some innovation in Chinese medical etiologies and pathogeneses of CHD. We also got some improvement in researches on Chinese medical syndromes in various fields. Many clinical studies have proved Chinese medicine and pharmacy is playing a role in preventing and improving CHD patients. In-depth basic researches on preventing and treating CHD by IM are gradually undergoing. Acting targets and mechanism are further clarified. Besides, we also pointed out the developing tendency of CHD researches and the current deficiency in CHD researches, hoping to provide reference for further studies in this field.

The aim of this paper is to apply Raman spectroscopy technique to develop rapid quantitative models for five kinds of Traditional Chinese Medicine containing CaCO3. In the experiment, Raman spectras of 67 batch of sample including Otolithum Sciaenae, Galaxeae Os, Ophicalcitum, Calcite, Stalactite and their mixture which had different content of CaCO3 were collected, and the quantitative models were established by using an improved siPLS to optimize the characteristic spectral bands and using the CaCO3 contents which were measured by EDTA titration method as references. Compared with the results by EDTA titration, the established quantitative model for CaCO, content showed a prediction result that the average relative deviation of the prediction results is 2. 71% and the average recovery rate was 100.46%, when the content is between 0.465 4-0.999 7, and when the characteristic spectral bands of 1 290-1 280, 730-714, 700-690, 660-650, 465-460, 455-445, 405-385 cm(-1) had been optimized. The result also showed that the model using Raman spectroscopy and based on an improved siPLS can get a rapid determination for contents of 5 kinds of Traditional Chinese Medicine containing CaCO3.

The aim of this paper is to clarify the mineral origin of traditional Chinese medicine (TCM) Yangqishi and Yinqishi and guide identification of the both, by X-ray diffraction (XRD) Fourier patterns. Morphological identification and conventional physical and chemical analysis wee used to identify 22 batches of Yangqishi and Yinqishi. It used XRD Fourier patterns which has been collected from sample powders to analyze phase composition. It has been found experimentally that the mineral origin of Yinqishi is Talc schist and the mineral origin of Yangqishi is tremolite and actinolite. The results also showed that the method using XRD can get not only an accurate but also rapid identification of Yangqishi and Yinqishi. There are many differences in medicinal properties, efficacy, indications and composition of Yangqishi and Yinqishi, so be careful not to mix them up.

Referring to the rules for agricultural seed testing (GB /T 3543-1995) issued by China, the test of sampling, seed purity, weight per 1 000 seeds, seed moisture, seed viability and germination rate had been studied for screening seed quality test methods of Pesudostellaria heterophylla. The seed quality from different collection areas was measured. The results showed that at least 6.5 g seeds should be sampled and passed through 10-mesh sieve for purity analysis. The weight of 1 000 seeds was determined by using the 500-seed method. The phenotypic observation and size measurement were used for authenticity testing. The seed moisture was determined under the higher temperature (130 ± 2) degrees C for 5 hours. The seeds were dipped into 0.2% TTC sustaining 1 hour at 40 degrees C, then the viability could be determined. The break dormancy seeds were cultured on sand at 10 degrees C. K cluster analysis was applied for the data analysis, the seed quality from different collection areas grading of P. Heterophylla was described as three grades. The seed quality of each grade should reach following requirements: for first grade seeds, germination rate ≥ 86%, 1 000-grain weight ≥ 2.59 g, purity ≥ 87%, moisture ≤ 13.1%; for second grade seeds, germination rate ≥ 70%, 1 000-grain weight ≥ 2.40 g, purity ≥ 77%, moisture ≤ 14.3%; for third grade seeds, germination rate ≥ 41%, 1 000-grain weight ≥ 2.29 g, purity ≥ 76%, moisture ≤ 15.8%. The seed testing methods for quality items of P. heterophylla had been initially established, as well as the primary P. heterophylla seed quality classification standard.

The aim of this paper is to apply near infrared spectroscopy techniques to construct a rapid identification method for 8 kinds of mineral Chinese Medicines containing carbonates. The qualitative model using clustering analysis method in OPUS software can identify accurately 8 kinds of carbonate-containing mineral Chinese medicines. The near-infrared quantitative model was established by using partial least squares method (PLS) for 7 mineral Chinese Medicines in which main component is calcium carbonate. Compared with the results by EDTA titration, the established quantitative analysis model for calcium carbonate content showed a good prediction result that when the content is between 47.61% -99.17%, the average relative deviation of the prediction result is 0.24% and the average recovery rate was 100.3%. The results also showed that the model using near infrared spectroscopy can get not only a rapid identification of the 8 mineral Chinese medicines containing carbonates, but also an accurate and reliabe content determination of calcium carbonate for the 7 mineral Chinese medicines which contain the component.
