AIM:To explore the polarized distribution of M 2 macrophages in the marginal region around lung adenocarcinoma , the marginal/central ratio and their effect on the prognosis .METHODS:Double immunohistochemistry staining was used to determine the distribution and the difference of CD 163 +/CD68 +( M2 ) macrophages in the marginal and central regions in 49 cases of lung adenocarcinoma in situ ( AIS), 11 cases of minimally invasive adenocarcinoma ( MIA) and 57 cases of invasive adenocarcinoma ( IA) in order to explore the effect and mechanism of the polarized distri-bution and the marginal/central ratio on the progression of lung adenocarcinoma .Single-factor Kaplan-Meier survival curve analysis and multivariate Cox survival analysis were employed to explore the relationship between the polarized distribution of M2 macrophages and the prognosis .RESULTS:Polarized aggregation of M 2 macrophages was observed in the marginal region of lung adenocarcinoma compared with that in the central region , and the difference was significant ( P<0.01 ) . Based on the median level , they were divided into high polarized group and low polarized group .In low polarized group , M2 macrophage count in AIS was not significantly different from that in MIA or IA .However, in high polarized group, M2 macrophage count in AIS was lower than that in MIA and IA in turn and there were statistically significant differences (P<0.01).Single-factor Kaplan-Meier survival curve analysis and log-rank test result showed that the number of M2 mac-rophages in the marginal region and marginal/central ratio were negatively correlated to the survival time (χ2 =44.71, P<0.01;χ2=21.75, P<0.01).Multivariate Cox survival analysis showed that the high polarized distribution of M 2 macro-phages in the marginal region and the marginal /central ratio were independent risk factors for the prognosis ( P<0.01 ) . CONCLUSION:There is a polarization effect of M2 macrophages on the marginal region of lung adenocarcinoma .The marginal polarization and the marginal/central ratio are independent risk factors of the prognosis .Therefore , it may be an effective method for the evaluation of the prognosis to judge the marginal polarization by preoperative puncture and to deter -mine the marginal/central ratio of M2 macrophages by postoperative biopsy .

Objective To perform the sample survey on the recognition degree of abdominal compartment syndrome (ACS) among domestic pediatric healthcare providers (PHCP) Methods Three hundred self‐designed questionnaires were distributed to the participants at the twelfth Chinese Medical Association Congress of Pediatric Critical Care Medicine in November 2011 .Results A total of 194 effective questionnaires were reclaimed with the recovery rate of 64 .7% .28 .9% (56/194)of respondents did not heard of ACS .49 .5% (96/194)of them heard of ACS ,but did not contact ACS .Only 21 .6% (42/194)of respondents were well fa‐miliar with ACS .Among the medical staffs who were aware of ACS (familiar or just heard of ) ,only 7 .2% (10/138)knew the real definition of ACS .83 .3% (35/42) of respondents who were familiar with ACS used the intravesical route to measure the intra -ab‐dominal pressure(IAP) .However ,only 57 .1% (20/35)of respondents knew the correct saline volume for measuring IAP .Conclusion The recognition degree of ACS is low among domestic PHCP .It is necessary to strengthen the ACS related education among do‐mestic PHCP for increasing the awareness of ACS and promoting its treatment .

Objective To explore the diagnostic value of ultrasonography of fetal congenital cystic adenomatoid malformation of the lung (CCAM), and to predict the prognosis according to ultrasonographic findings. Methods The chest of 19 fetus with CCAM was multi-sectionally scanned with two-dimensional ultrasonography. The position, appearance and size of mass were observed, and complications were continuously followed. Results CCAM was pathologically confirmed in 13 fetus after induced abortion. One neonatal died, while CCAM in other 5 fetus disappeared before 36 weeks. The mass of typeⅠCCAM became smaller and smaller, and eventually disappeared. The echo-free spaces in typeⅡbecame smaller and fewer, and the strong echo weakened to the same level as normal lung. For type Ⅲ, the echo of solid mass weakened to the same level as normal lung, or transformed to typeⅡ gradually, and finally recovered to normal echo of lung as the gestational age increased. During follow up, there were 10 fetus (10/19, 52.63%) that lung adenoma cyst increased with the gestational age increased, and the heart, mediastinal shifted, pleural effusion, and (or) fetal edema were observed. Conclusion Ultrasound examination is a reliable method for the diagnosis of CCAM, and enable to predict the prognosis of the affected fetuses. If heart and mediustinum displacement, pleural effusion, hydrops fetal or other abnormalities exist, it's necessary to terminate the pregnancy.

Objective To investigate the effect of slice orientation on the popliteomeniscal fasciculi (PMF) MR imaging and its normal MRI appearances. Methods Volumetric MRI data of 40 knees of healthy volunteers were acquired using an isotropic 3D turbo spin echo (TSE) MR sequence. The posterior tangential line to both femoral condyles was used as the reference line, and the long axis sectional images of the popliteal hiatus region were reformatted at 0°, 15°, 30°, 45°, 60°, 75° and 90° to the reference line. The MRI appearances of the PMF were scored respectively and classified. The final scores of the PMF at each slice angle were statistically analyzed by a repeated measure ANOVA. Results At 0°, 15°, 30°, 45°, 60°, 75° and 90° slice angles: scores of the anteroinferior fasciculi were (1.7±0.7), (1.8±0.6), (1.9±0.6), (2.0±0.7), (1.9±0.7), (1.8±0.8) and (1.0±0.5),respectively. Scores of the posterosuperior fasciculi were (1.5±0.7), (1.9±0.7), (2.1±0.6), (2.2±0.6),(2.2±0.6), (2.0±0.8) and (1.7±0.8), respectively. There were statistically significant differences in the average scores at each slice angle for both anteroinferior fasciculi (F = 29.744, P = 0.000) and posterosuperior fasciculi (F = 19.770,P =0.000). The anteroinferior fasciculi and the posterosuperior fasciculi had highest average scores at the angle of 45°. The percentage of type A, B and C of anteroinferior fascicali were 20.0% (8/40), 75.0% (30/40) and 5.0% (2/40), respectively. The percentage of type A, B and C of posterosuperior fasciculi were 37.5% (15/40) ,62.5% (25/40) and 0% (0/40) ,respectively. Conclusion The anteroinferior fasciculi and the posterosuperior fasciculi can be well depicted at the angle of 45° slice orientation.

Objective:To explore the possibility of using peritoneal alternatively activated M2 macrophages to prevent rejection after islet allotransplantation in a murine model.Methods:Peritoneal monocytes from C57BL/6 mice were induced and modulated to M2 and M0 macrophages in vitro,then the phenotype of macrophage was assessed by flow cytometry.C57BL/6 mice were induced diabetic by streptozotocin (STZ) injection and transplanted with islets isolated from BALB/c mice under the left kidney capsule.The recipients were randomly divided to 3 groups (n=8).A total of 2.5× 106 M2 macrophages were injected intravenously at 0,3,7 d after transplantation in islet+M2 group;2.5×106 M0 macrophages were injected intravenously at 0,3,7 d after transplantation in islet+M0 group;the mice in islet+PBS group were injected with PBS.Blood glucose was monitored after transplantation.On day 10 after transplantation,2 recipients in each group were randomly selected and sacrificed,and the left kidneys were resected for pathological examination.Results:Achievement of euglycemia was significantly prolonged after islet transplantation in the islet+M2 group than that in the other two groups (P＜0.01).The median survival time of islet allografts in the islet+PBS group,the islet+M0 group,and the islet+M2 group were 6.5 (4-10),7.5 (4-10),and 24(＞ 15) d,respectively.Pathological examination also showed that the grafts in islet+M2 group remained an intact structure with positive insulin stain and no apparent lymphocytes infiltration,while the graft was rejected in other 2 groups with negative insulin stain and massive lymphocytes infiltration.Conclusion:Peritoneal alternatively activated M2 macrophages can prevent rejection after islet allotransplantation,prolong the survival time of islet allografts and enhance the tolerance of the recipient to blood glucose in mice.
