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.

Objective To observe the expression of small ubiquitin?related modifiers(SUMO)protein in normal cultured human lens epithelial cells(SRA01/04)and discuss regulation effects of SUMO protein on oxidative stress induced by high glucose. Methods The expression and local?ization of SUMO 1,2/3,4 was detected in normal cultured SRA01/04 cells through immunocytochemistry. The mRNA expression levels of SUMO 1?4 were examined by RT?PCR after the SRA01/04 cells treated with high glucose media at different concentrations and time points. Samples were grouped by medium concentrations(glucoses 5.5 mmol/L,12.5 mmol/L,25 mmol/L,50 mmol/L respectively for 24 h)and by treatment time(0 h, 6 h,12 h and 24 h respectively). After highly efficient transfection of GFP?SUMO2 into SRA01/04 cells,the survival and apoptotic rates of transfect?ed and un?transfected cells treated with high glucose was detected by CCK8 method and AV/PI double staining flow cytometry. Results The immu?nocytochemistry results showed that SUMO1,2/3,4 proteins were mainly located in the nucleus of SRA01/04 cells and part of SUMO2/3 was in the cytoplasm. RT?PCR results showed that compared with the low?glucose group,the mRNA expression of SUMO1?4 was increased along the increas?ing glucose concentration in the high?glucose group(P<0.05). Compared with 0 h,the mRNA expression of SUMO1?4 was enhanced at 6 h,12 h and 24 h(P<0.05)in the high?glucose group treated at 50 mmol/L concentration. Compared with the un?transfected cells,the survival rate was in?creased and the apoptotic rate was decreased in GFP?SUMO2 transfected cells in oxidative stress induced by high glucose(P<0.05). Conclusion SUMO protein was positively expressed in SRA01/04 cells and the expression of SUMO mRNA was affected by oxidative stress induced by high glu?cose.

Objective To evaluate the role of spinal sigma-1 receptors in the maintenance of bone cancer pain (BCP) in rats and the relationship with extracellular signal-regulated kinase (ERK).Methods Part Ⅰ Twenty-four female Sprague-Dawley rats,weighing 180-220 g,were randomized into 2 groups using a random number table:sham operation group (S group,n =4) and BCP group (n =20).BCP was induced by inoculating Walker 256 mammary gland carcinoma cells into the medullary cavity of the right tibia.Four rats were sacrificed on day 10 after inoculation in S group or on day 3,5,7,10 and 14 after inoculation in BCP group,and the L4-6 segments of the spinal cord were removed to measure the expression of sigma-1 receptors by Western blot.Part Ⅱ Forty female Sprague-Dawley rats,weighing 180-220 g,were randomized into 4 groups (n =10 each) using a random number table:sham operation group (S group),sigma-1 receptor inhibitor BD1047 group (BD group),BCP group,and BCP + BD1047 group (BCP + BD group).On day 10 to 14 after inoculation,normal saline 20 μl was injected intrathecally once a day in S and BCP groups,or BD1047 120 nmol/20μl was injected intrathecally once a day in BD and BCP + BD groups.Mechanical paw withdrawal threshold (MWT) to yon Frey filament stimulation was measured one day before inoculation,on day 3,5 and 7 after inoculation,and on day 10,12 and 14 after administration.After measurement of MWT on day 14 after inoculation,the rats were sacrificed and the L4-6 segments of the spinal cord were removed to determine the expression of phosphorylated ERK (p-ERK) by Western blot.Results Part Ⅰ Compared with group S,the expression of sigma-1 was significantly up-regulated and peaked on day 10 after operation in group BCP.Part Ⅱ Compared with S group,no significant changes were found in MWT and p-ERK expression at each time point in BD group,and MWT was decreased and p-ERK expression was up-regulated in BCP and BCP + BD groups.Compared with group BCP,after intrathecal injection of BD1047,MWT was significantly increased and the expression of p-ERK was down-regulated in BCP + BD group.Conclusion Spinal sigma-1 receptors are involved in the maintenance of BCP in rats possibly through promoting phosphorylation of ERK.
