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”.

Objective To investigate the risk distribution of breast cancer for location and time of recurrence metastasis in molecular subtype.Methods We studied retrospectively the female patients who were diagnosed as invasive ductal breast cancer in our hospital from July 2004 to June 2012,detected ER,PR,and HER2 expressions in the paraffin sections.The patients with recurrence metastasis were divided into local recurrence and distant metastasis with the first transfer site as standard for analyzing the distribution in molecular subtype and the time of the first site of recurrence metastasis.Results Sixty two patients were encountered recurrence metastasis,including 23 patients with local recurrence,and 39 patients with distant metastasis,death 11.The rates of distant metastasis for patients who belonged to HER2 type and basal-like type were higher than that of local recurrence (P =0.01,P =0.001).The risk distribution of recurrence metastasis time in molecular recurrence metastasis showed that 35 percent of recurrence metastasis time of luminal A type was first 3 years,75 percent of molecular subtype of basa1-1ike type recurrence metastasis time in first 3 years and advanced.The peak of luminal B and HER2 type was first 3 years,and very low in 5 years.Conclusions Molecular subtype of breast cancer is an important complement for TNM method in accurately assessing the patients of recurrence metastasis for location and time,and is helpful for the individual screening of patients for recurrence metastasis.

The etiological agent of severe acute respiratory syndrome (SARS) was identified as a new coronavirus, termed SARS-CoV. Establishment of an efficient and sensitive diagnostic system of SARS-CoV genetic materials is crucial for SARS control. In this study, we quantified SARS-CoV mRNAs in both infected cell culture lysate and in supernatant by using Real-time quantitative revere transcription-PCR based on EvaGreen鈩?dye and Taqman-MGB probes. For extensive evaluation of sensitivities and specificities, 13 pairs of primers and 4 probes were designed based on different genes of SARS-CoV. Glyceraldehydes-3-phosphate dehydrogenase (GAPDH) was selected as the internal control gene. Results showed that S-gene-specific PCR was the most sensitive for detection, but because of its sequence variability in the different viral strains, primers and a probe based on the N gene were suitable substitutions. Meanwhile, we found the mRNA concentrations in cell culture lysates were much higher than in cell supernatant and facilited more sensitive detection of the SARS-CoV.

Objective To investigate the expressions of apoptosis stimulating protein of P53 (ASPP)family in colorectal carcinoma tissue and to explore their relationship with the clinicopathological characteristics of colorectal carcinoma,and to clarify the effect of ASPP family in the development of colorectal carcinoma.Methods 45 cases of colorectal carcinoma tissue and 20 cases of healthy controls were selected. Among 45 cases of colorectal carcinoma tissue, there were 1 1 cases of well differentiated colorectal carcinoma, 2 1 cases of moderately differentiated colorectal carcinoma,and 13 cases of poorly differentiated colorectal carcinoma;7 cases of T1 stage colorectal carcinoma,8 cases of T2 stage colorectal carcinoma,25 cases of T3 stage colorectal carcinoma,and 5 cases of T4 stage colorectal carcinoma;19 cases of N1 stage with lymph node metastasis,26 cases of N0 stage without lymph node metatasis.The expressions of ASPP1,ASPP2,and iASPP in 45 cases of colorectal carcinoma tissue and 20 cases of normal colon tissue were detected by immunohitochemistry SP method,and the correlations between the expressions of ASPP family and the pathologic typing,infiltrative depth,and lymph node metastasis of colorectal carcinoma were analyzed. Results ①The immunohitochemical staining results showed that the ASPP family members expressed in colorectal carcinoma tissue and normal colon tissue, and there were no significant differences in ASPP1 and ASPP2 positive rates between colorectal carcinoma tissue and normal colon tissue (P>0.05);the positive expression rate of iASPP in colon cancer tissue was higher than that in normal colon tissue (P<0.01).② The expression of ASPP1 in colon caner tissue had no correlation with the differentiation degree of tumor cells (rs=0.163,P>0.05);the expression of ASPP2 positive rate was decreased when the differentiation degree of tumor cells reduced,they had positive correlation (rs=0.454,P=0.002);the expression of iASPP in colon cancer tissue had no correlation with the differentiation degree of tumor cells (rs=-0.171,P>0.05).③ The expression of ASPP1 in colon caner tissue had no correlation with the infiltrative depth of tumor (rs=-0.268,P>0.05);the expression of ASPP2 positive rate was decreased when the tumor infiltrative depth increased,they had negative correlation (rs=-0.348,P<0.05);the expression of iASPP in colonic carcinoma caner tissue had no correlation with the infiltrative depth of tumor (rs=0.231,P>0.05).④The expressions of ASPP1,ASPP2, and iASPP in colon caner tissue had no correlation with lymph node metastasis (rs=0.089,rs=0.044,rs=0.210, P>0.05).Conclusion The expression levels of iASPP in colon cancer and normal colon tissues are different,it may be useful for the diagnosis, differential diagnosis and evaluation in benign and malignant colorectal diseases. The expression of iASPP is negatively correlated with the pathologic typing and neoplasm staging of colorectal carcinoma,it indicates that iASPP can be used as a indicator in judging the prognosis of colorectal carcinoma.
