Circulating endothelial cells (CEC) are endothelial cells which are detected in the peripheral blood. There are very few CEC in healthy adults while the number is obviously increasing in patients with arthrosclerosis, diabetes mellitus, lupus erythematosus, et al. Nowadays, flow cytometry analysis and immunomagnetic isolation for CEC are employed successfully in clinic and scientific research. Several research findings have confirmed that there is intimate relation between CEC and tumorigenesis. Because of the important role in angiogenesis and tumor growth, CEC would be a perspective tumor marker in antiangiogenesis and would also predict the chemotherapy efficacy.

Objective To explore the types, clinical pathologic and immunohistochemical features of spindle cell tumors of the uterine and broad ligament. Methods Clinical pathological files of spindle cell tumors in the uterine and broad ligament from 2007.12 to 2015.12 were reviewed. Results The primary sites of the 145 cases was cervical in 11 cases (7.58%), uterine body in 119 cases (82.07%), the broad ligament in 12 cases (8.28%), and uterine or cervix and the abdominal wall in 3 case (2.07%). Histopathological types of the 145 cases was smooth muscle origin in 126 cases (86.90%), of which 120 cases had benign leiomyoma, 3 cases had uncertain malignant potential and 3 cases had leiomyosarcoma;endometrial stromal origin in 15 cases (10.34%), including endometrial stromal nodule (5 cases), endometrial stromal sarcoma (10 cases); endometrial stromal- variant (3 cases, 2.07%), including endometrial stromal nodule associated with smooth muscle differentiation (2 cases), endometrial stromal sarcoma associated with smooth muscle differentiation (1 case); gastrointestinal stromal tumor (1 case, 0.68%). Conclusions Origin of spindle cell tumors of the uterine and broad ligament is mainly smooth muscle, endometrial stromal origin, and endometrial stromal tumor variants, and gastrointestinal stromal tumors in rare cases. We need to combine the clinical site, pathological morphology and immunohistochemistry for diagnosis and differential diagnosis.

Based on the theory of the rise and fall of qi-blood in meridians, Professor GAO Yu-chun harmonizes the qi-blood and yin-yang for diagnosis and treatment of hypertersion from liver, spleen and kidney. With reference of the academic idea of“Preventive Acupuncture”, he investigated the qi and blood, treated diseases in the upper part by managing the lower part, pay attention to the syndrome differentiation of excess and deficiency, the different of acupoint property, and the treatment of acupuncture or moxibustion. Thus, through balancing yin and yang, the qi and blood are regulated to reach the therapeutic aim of“yin and yang in equilibrium”.

Immunological rejection is the major barrier to successful transplantation.The immune response to an allograft is an ongoing dialogue between the innate and adaptive immune system that will lead to the rejection of allograft.Activation of elements of the innate immune system,triggered as a consequence of tissue injury sustained during cell isolation or organ retrieval and ischemia reperfusion,will initiate and amplify the adaptive response.Identifying the molecular pathways that trigger tissue injury,signal transduction and rejection facilitates the identification of targets for the development of immunosuppressants.

Objective To establish a new RP-HPLC method for simultaneous determination of chlorogenic acid,forsythin, and baicalin in shuanghuanglian powder for injection after ultrasonic atomization. Methods Hypersil ODS2 C18(250 mmí4. 6 mm,5 μm) was used as the chromatographic column. The mobile phase was methanol-0. 2% phosphate acid solution (4060). Flow rate was 1. 0 mL·min-1 . Sample volume was 5μL. Column temperature was 30℃. Detection wavelength was 324 nm at 0-10 min and 277 nm at 10-25 min. Results Contents of chlorogenic acid,forsythin, and baicalin had good linear relationship with the respective peak area (r≥0. 999 7) within the scope of the sample volume. The RSD was <2% for precision, reproducibility, and stability. Recovery rate was 98. 50%-101. 12% (n=6). Conclusion The method is rapid, accurate and reproducible, with high resolution. It can determine the content of three kinds of components at the same time. The three components in shuanghuanglian powder for injection did not change significantly before and after ultrasonic atomization.
