Chinese Caterpillar Fungus (CCF) is one of the rare Chinese traditional drugs. As the resource is reducing sharply, the price is rising higher and higher, and there have been much more adulterants in the markets, but until now we don't have a scientific and accurate research on the identification study for this drug. On the basis of resource investigation, during the study of the samples collected by ourselves and the specimens stored in the museum, using the macroscopic and microscopic methods, referring to the literatures of entomology, emphasizing on the characteristics of polypide part, we have studied this species in detail of the macroscopic characters such as the insertion position of the stroma part, the annulations and segments of the caterpillar, the abdominal leg, the pinaculum, and the microscopic characters of the body wall; firstly added the microscopic character of the crotchets on the planta of abdominal leg. The result turned out that the characters which we have studied are regular and stable, and it have laid the foundation for the powder products and patent medicines which have used the crude drug of CCF.

Purpose To investigate the value of three-dimensional speckle tracking echocardiography in evaluating the cardiac function in breast cancer patients treated with Anthracycline. Materials and Methods Thirty-two breast cancer patients were followed with three-dimensional echocardiography prechemotherapy (group A), 2 cycles (group B) and 4 cycles (group B) postchemotherapy to compare left ventricle global longitudinal strain (GLS), global radial strain (GRS), global circular strain (GCS), global area strain (GAS), early diastolic global area strain rate (EASR), and early diastolic 3D velocity (3DVe). Results GCS, GAS and EASR were signiifcantly lower in group C than group A (t=3.555, 3.692 and 3.590, P<0.01);EASR was lower in group B than group A with statistical significance (t=2.190, P<0.05). GLS, GRS and 3DVe were not significantly different among three groups (F=2.305, 1.957 and 1.205, P>0.05). EASR was negatively correlated with IVRT (r=-0.44, P<0.01); EASR was positively correlated with Em (r=0.49, P<0.01) and Em/Am (r=0.32, P<0.01). GSR was positively correlated with Sm (r=0.21, P<0.05). Conclusion Three-dimensional echocardiography sensitively detects the early changes in diastole function in breast cancer patients treated with Anthracycline.

Recently, there are many prominent problems about the quality ofIndigo Naturalis. To explore the underlying reasons, both ancient and modern herbal literatures were reviewed. Through the organization of recordings onIndigo Naturalis, the traditional process method required soaking and fermentation, stiring and depositing, foaming and shade drying. The currently usedIndigo Naturalis was mostly isolated and purified from crude deposit -“Cu-Dian.” The modern process technique ofIndigo Naturalis was gradually deviated from the traditional processing method. This paper also discussed the quality standards ofIndigo Naturalis. The author considered that the current standard on descriptions ofIndigo Naturalis characteristics was deviated from the traditional morphological features ofIndigo Naturalis, which should be further researched and verified. Therefore, this study provided certain references for the quality control and market supervision ofIndigo Naturalis.

Chinese Pharmaceutical Journal 2013;48(22):1951-1954
OBJECTIVE: To establish a method for determination of D(-) sulbenicillin sodium in sulbenicillin sodium for injection by HPLC/MS. METHODS: The analysis was performed on a SHIMADZU VP-ODS column with mobile phase consisting of 0.01 mol·L-1 ammonium acetate solution-methanol (90:10) at a flow rate of 0.6 mL·min-1. The detection was performed by Multiple Reaction Monitoring (MRM) scanning mode with ESI negative ion mode. RESULTS: D(-) and L(+) sulbenicillin could be effectively separated. Good liner relationship was achieved when the concentration of D(-) sulbenicillin was in the range of 1.03-51.90 μg· mL-1 (r = 0.9997). The average recovery rate was 99.98% at three levels (RSD = 0.30%, n = 9). CONCLUSION: The MRM method is accurate, reliable, and can be used for the determination of D(-) sulbenicillin sodium in sulbenicillin sodium for injection.

BACKGROUND:Cartilage injury is stil one of the clinical problems difficult to be treated completely so far. Recently, the discovery of synovial mesenchymal stem cells (SMSCs) has brought about the new hope to cartilage repair.
OBJECTIVE:To explore the process concerning SMSCs-based therapy for cartilage repair in the past few years, such as the characteristics of SMSCs, culture conditions, preclinical and clinical studies, and then to summarize the literatures published in recent years.
METHODS:A computed-based online search of PubMed and SpringerLink databases was performed using the key words of“synovial mesenchymal stem cells, cartilage repair”for literatures published from January 1993 to May 2013.
RESULTS AND CONCLUSION:Final y, 37 articles were included. SMSCs have a greater proliferative capability, colony-forming potential and chondrogenic potential than other mesenchymal stem cells. The diseases such as osteoarthritis and rheumatoid arthritis can influence the characteristics of SMSCs. Numerous articles have aimed at the studies of cellculture in vitro and celltransplantation in vivo. However, the process of SMSCs therapy is mostly at its preliminary stage. Reports on its unique characteristics, optimal culture conditions and the high-quality clinical studies are stil largely lacking. In a word, though further studies are needed, SMSCs appear to be a promising cellsource for cartilage repair in the future.

Epmedii Folium is a commonly used traditional Chinese drug, and is beneficial for the "liver" and "kidney" s function in Chinese medicine. Recently, the origin of this drug is more complex. Most of the identification studies are emphasized on the species certified by the pharmacopoeia and other related species from the same genus of Epimedium, but few was emphasized on the counterfeit. In this paper, one counterfeit of Epmedii Folium, identified as the dried leaf of Quercus variabilis (Fam. Fagaceae), has been reported based on field investigation, comparing specimen of Epmedii Folium and Q. variabilis,using the macroscopic, microscopic and TmC methods. It is resulted that they could be identified clearly not only by the macroscopic features, such as the vein character and the tooth apex, but also by the microscopic features, such as the vascular bundles of the midrib, the non-glandular hair, the anticlinal wall of the epidermis cell and the calcium oxalate crystal. Furthermore their TLC chromatograms showed also difference. This study will give reference for the identification of Epmedii Folium and the related supervision and inspection work.
