Aim To explore the effects of depression on tumors, as well as its molecular mechanisms. Methods The chronic unpredictable mild stress model (CUMS) was constructed. Tumor was inoculated after behavioral test, and the differences in serum norepinephrine and tumor volume between groups were detected. Breast cancer cells were stimulated by administration and invasion, migration, proliferation and cell cycle distribution were detected. Western blot and immunofluorescence were utilized to detect cell surface receptors and intracellular signaling pathways. Results Depression up-regulated the level of norepinephrine (N E) and increased the phosphorylation of p38 MAPK, resulting in increased malignancy of breast cancer cells. Conclusions Depression may increase the malignancy of breast cancer through norepinephrine-induced p38 MAPK signaling pathway, thus increasing the malignant degree of breast cancer.

Objective To evaluate the influence of epimeric glycyrrhizic acid on production of endothelin-1 (ET-1) in the lungs induced by ischemia-reperfusion(I/R) injury.Methods Twenty healthy long-ear white rabbits of both sexes, weighing 1.1-2.1kg were randomly divided into 2 groups: group I I/R alone ( n = 10) and group II I/R + epimeric glycyrrhizic acid (n = 10). The animals were anesthetized with thiopental 25 mg?kg-1 and tracheotomized and mechanically ventilated (FiO2 = 100% , VT = 10-13 ml?kg, RR = 20-30 bpm, I:E= 1: 1.2). Anesthesia was maintained with fentanyl, thiopental and vecuronium. Femoral artery was cannulated for continuous direct BP monitoring. MAP was maintained at 70-90 mm Hg during experiment. Right interval jugular vein was cannulated. Catheter was inserted into right atrium for fluid administration, blood sampling and right atrial pressure monitoring. Chest was opened and the hilum of right lung was mass-ligated to induce ischemia for 60 min and then released for reperfusion for 60 min. Epimeric glycyrrhizic acid 30 mg?kg-1 was given iv 30 min before ischemia of the right lung. Blood samples were taken from right atrium and femoral artery for determination of ET-1 concentration before ischemia of right lung (T0) and 1 and 5 min after right lung started being perfused (T1 , T2). At the end of 60 min reperfusion of the right lung, the animals were sacrificed and lungs (right and left) were removed for electron microscopic examination. Results In group 1 at T, the ET-1 levels in the blood from both femoral artery and right atrium were significantly higher than the baseline (T0) and the ET-1 concentration in the blood from femoral artery was significantly higher than that from right atrium. In group II there was no significant difference in blood ET-1 concentration between T0 and T, .Conclusion Ischemia-reperfusion induces increased production of ET-1 in the injured lung. Epimeric glycyrrhizic acid can inhibit the increase in the production of ET-1 in the induced by I/R.

OBJECTIVETo investigate the changes of cerebral metabolism in rabbit model of hemorrhagic shock by using proton magnetic resonance spectroscopy(PMRS).

METHODSTen New Zealand white rabbits were used for construction of the model of acute hemorrhagic anemia. 1H-MRS was performed before and at the time-peint of 30, 90, and 180 min after hemorrhagic shock. The concentrations of NAA, Cr, Cho, Lac, and NAA/Cr and Cho/Cr ratios were estimated.

RESULTSHemorrhagic shock was associated with significant reductions in red blood cell count, hemoglobin level, hematocrit, pH, and PaCO, and elevations of blood lactate and PaO. The ratios of NAA/Cr at 30 min, 90 min and 180 min after shock were (1.50±0.09), (1.37±0.09) and (1.27±0.10), respectively, which were significantly lower than those before shock (2.11±0.16) (P <0.05) (1.16±0.05) and (0.97±0.04) at 30 min and 90 min after shock, respectively, which were significantly lower than those pre-shock (1.38±0.08) (P <0.05). The ratis of Cho/Cr at 30 min and 90 min were (1.16±0.05) and (0.97±0.04), respectively, which were significantly lower than those before shock (1.38±0.08) (P <0.05).

CONCLUSIONMRS can noninvasively and dynamically detect brean metabolic changes in early hemorrhagic shock, and has positive significance for early diagnosis and prognosis assessment of hemorrhagic shock.

OBJECTIVETo investigate Chinese medicine (CM) patterns and epidemiological characters of patients with influenza-like illness (ILI) syndromes in clinics in China.

METHODSA prospective multi-center observational epidemiology survey on the clinical CM patterns of ILI and its prevalence was conducted from September 2009 to April 2010. A unified survey questionnaire was developed for data collection of ILI symptoms and CM patterns. Totally 45 hospitals from 22 provinces, municipality cities and autonomous regions of China participated this study. The collected data were input by EPI-data v3.1 and analyzed by SPSS 18.0, which included descriptive analysis and Chi-square test for group comparison.

RESULTSA total of 5,967 ILI patients were included in the study. The proportion of the 18-34 aged group (56.2%) was the largest; students (41.0%) were more than other occupations. Majority of the patients had the wind-heat invading Lung (Fei) syndrome (76%), while in Southwest China mainly wind-heat invading Lung syndrome and wind-cold tightening the exterior syndrome occurred. The typical symptoms of ILI were ranked as fatigue (80.9%), cough (72.2%), sore throat (67.2%), muscular soreness (67.1%), headache (65.4%), aversion to cold (60.1%), thirst (55.1%) and nasal obstruction (48.1%).

CONCLUSIONSThe ILI patients in clinics were mainly teenagers and young adults. In regard to CM syndrome, wind-heat invading Lung syndrome prevailed in all regions except the Southwest China. The characteristics of CM syndrome of ILI patients may be relevant to age and region distribution.

OBJECTIVETo develop a new imaging agent, (99m)Tc-Rituximab, for sentinel lymphoscinti-graphy and investigate its feasibility in detecting the sentinel lymph node (SLN) for breast cancer patient.

METHODS(99m)Tc-Rituximab was prepared by introducing (99m)Tc directly into the mclecule of Rituximab, thus a new kind of lymphoscintigraphy agent ((99m)Tc-Rituximab) was produced. Five Bal b/c mice and ten breast cancer patients underwent dynamic SLN mapping procedures using (99m)Tc-Rituximab. Axillary lymph node status in breast cancer patients were evaluated with the fusion images, which was processed by computer software. With ROI technique, SLN/background ratio and the rate of SLN uptake were calculated and the dynamic curve of SLN uptake was drawn. The other 61 breast carcinoma patients underwent routine lymphatic mapping. Sentinel lymph node biopsy (SLNB) and axillary lymph node dissection (ALND) were both performed in all 71 patients. Fresh SLNs and all axillary nodes were sent for pathological examination using hematoxylin and eosin (H&E) staining.

RESULTS(99m)Tc-Rituximab, with a yield of about 95.0%, can show SLN status in both mice and patients. The fusion image showed SLNs clearly, even the depth of SLNs in the axilla. The results of dynamic SLN mapping showed visible SLN starting from 10 min, up to 16 h after injecting tracer, however, secondary lymph nodes were not detectable at all. In mice, the ratio of SLN/background was 2.1, the rate of uptake was about 3.0% to 3.5%, and the equation of the curve was produced as: y = 0.036x + 2.7875, r(2) = 0.9787. For breast cancer patients, the uptake rate was different from case to case, but the cure seemed to be consistent with logarithm. The result of SLNB and ALND showed that the sensitivity and accuracy of SLNB was both 100.0%. The average number of SLNs found in each case was 2.6. Of nineteen breast cancer patients (26.8%) with lymph node metastasis, 11 were found to only have SLN metastasis.

CONCLUSION(99m)Tc-Rituximab, as a new tracer to mapping sentinel lymph node for breast cancer patient, is able to show the status of sentinel lymph node reliably. The fusing image is easy to obtain and be interpreted by the clinician.

Background: Circulating endometrial cells (CECs) have been reported to be present in the peripheral blood of women with endometriosis (EM), providing clear and specific evidence of the presence of ectopic lesions. In this study, we established a method with a high detection rate of CECs, assessed the diagnostic value of CECs for EM and compared with serum CA125, and proposed a hypothesis for the pathogenesis of EM from the new perspective of CECs. Methods: The participants were enrolled prospectively from October 2015 to July 2016. The peripheral blood samples were collected from 59 participants, and the blood cells were isolated for immunofluorescence staining via microfluidic chips. The cells that were positive for vimentin/cytokeratin and estrogen/progesterone receptor and negative for CD45 were identified as CECs. The serum CA125 level was tested with electrochemiluminescence immunoassay. Results: The detection rate of CECs reached 89.5% (17/19) in the EM group, which was significantly higher than that of the control group (15.0% [6/40], P < 0.001) and was independent of menstrual cycle phases. Furthermore, a positive CEC assay detected 4/5 cases of Stage Ⅰ–Ⅱ EM. In contrast, a positive CA125 test had limited value in detecting EM (13/19, 68.4%) and detected only one case of Stage Ⅰ–Ⅱ EM. Conclusion: CECs are promising biomarkers for EM with great potential for a noninvasive diagnostic assay.
