OBJECTIVETo investigate the expression of Fas/FasL in infantile hemangiomas and discuss the role of Fas/FasL in the pathologic evolution of infantile hemangioma.

METHODThe EnVision immunohistochemical stain and RT-PCR technique was used to examine the expression of Fas/FasL protein and mRNA in the infantile hemangiomas.

RESULTS(1) In the early and middle proliferating stage, a number of infantile hemangioma cells expressed Fas. In the late proliferating stage, the number of positive cells increased obviously and the expression of Fas mRNA was reaching the strongest level. In the early regressing stage the Fas still existed in some cells and after that the expression decreased quickly. (2) Up to the middle proliferating stage, there were a few of FasL(+) cells foound. In the late proliferating stage, the number of FasL(+) cells increased significantly. From the early regressing stage, the number of FasL(+) cells decreased rapidly and disappeared.

CONCLUSIONThere may exist significant correlation between the expression of Fas/FasL and the development of the infantile hemangioma cells. The apoptosis of the infantile hemangioma cells mediated by Fas/ FasL may be the major reason of the spontaneous involution of infantile hemangioma.

The aim of this study was to investigate the relationship between the plasma levels of chemokine CCL-2/MCP-1 and acute graft-versus-host disease (aGVHD) and/or idiopathic pneumonia syndrome (IPS) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). ELISA assays were used to detect the plasma level of CCL-2/MCP-1 of 22 patients who received allo-HSCT, including 14 patients without or with grade I, 8 patients with grade II - IV aGVHD, respectively. 8 out of 22 patients were also diagnosed with IPS clinically. The dynamic changes of the plasma levels of CCL-2/MCP-1 chemokine and its correlation with aGVHD and/or IPS were analysized retrospectively. The results showed that the plasma levels of CCL-2/MCP-1 in the patients with moderate and serious aGVHD (grade II - IV) significantly increased, as compared with that prior to allo-HSCT (p < 0.05). The plasma levels of CCL-2/MCP-1 in the patients with aGVHD and/or IPS were higher significantly than those without any of these complications (p = 0.001). The retrospective analysis indicated that the plasma levels of CCL-2/MCP-1 in the patients with IPS significantly increased (p = 0.006). It is concluded that plasma level of CCL-2/MCP-1 correlates with aGVHD and/or IPS, and plays a role in the pathogenesis of these complications.

OBJECTIVETo observe the impact of heat-sensitive moxibustion on lung function in chronic persistent bronchial asthma and analyze its effect on the improvement of life quality as well as compare its efficacy with Seretide inhaler.

METHODSFifty-seven cases were divided into a heat-sensitive moxibustion group (28 cases) and a Seretide group (29 cases) according to the random number table. In heat-sensitive moxibustion group, the therapy of heat-sensitive moxibustion was applied to the regions at the level of Feishu (BL 13) and Geshu (BL 17), or to the heat-sensitized points in the region 6 cun lateral from the 1st and 2nd intercostal spaces in the chest. The treatment was given continuously for 8 days, once per day, 12 treatments should be ensured in the later 22 days of the 1st month. In the later two months since then, 15 treatments should be ensured each month (< or = 1 treatment each day). In Seretide group, Seritide manufactured in GlaxoSmithKLine was used, one inhalation each time, twice per day. The cases in both groups were received treatment for 3 months. The changes in lung function such as forced expiratory volume one second (FEV1), TCM symptoms score, Asthma Control Test (ACT) and St George's Respiratory Questionnaire (SGRQ) were assessed and compared between two groups and within group separately.

RESULTSLung function as FEV1 was improved in either group (P < 0.05, P < 0.01). The terminal improvement effects on symptoms of Chinese medicine, life quality and others were same between two groups (all P > 0.05). But the improvements in general situation, chills, fever and sweating in heat-sensitive moxibustion group were superior to those in Seretide group (both P < 0.05). Concerning to the improvement in respiratory symptoms, the effect of Seretide was better than that of heat-sensitive moxibustion (P < 0.05).

CONCLUSIONHeat-sensitive moxibustion improves lung function, relieves clinical symptoms and benefits life quality for patients with chronic persistent bronchial asthma. It's efficacy on the disease is equal to the internationally-recognized effect of Seretide.

OBJECTIVETo investigate the expression and role of glucose transporter-1 (Glut1) in infantile hemangioma.

METHODSFifty-two samples from infantile hemangioma, 25 in cavernous venous malformation, 9 in arteriovenous malformation, 2 in capillary malformation and 5 in normal skin samples were involved in this study. The EnVision immunohistochemical stain was used to investigate the expression of Glut1 protein in these samples.

RESULTSIn the early proliferating stage, a number of endothelial cells expressed Glut1. In the middle proliferating stage, most of vascular endothelial cells and scattered endothelial cells expressed Glut1. In the late proliferating stage, the expression of Glut1 decreased quickly. In the involuting stage, all hemangioma samples didn't express Glut1. All of the samples from the cavernous venous malformations, arteriovenous malformations, capillary malformations and normal skin had no expression of Glut1.

CONCLUSIONSGlut1 may be one of the phenotypes of infantile hemangioma endothelial cells in their development, rather than the inherent character. The expression of Glut1 changes according to the metabolic need of infantile hemangioma cells.

Objective To explore the retrograde contamination of drainage bag outlets,and provide basis for the formulation of related guideline for healthcare-associated infection(HAI)management. Methods On October 14,2016,with sterile manipulation,urine,5% glucose solution,glucose normal saline,sterile water,and 0.9% nor-mal saline were injected into anti-reflux drainage bags(anti-reflux group)and common drainage bags(common group)respectively,entrances of bags were sealed and bags were hung in two ways:outlets were 10 cm away from the ground(suspended group)and touched the ground(ground-touching group)respectively,specimens were col-lected from bag outlets to perform bacterial culture every 3 days,a total of 10 times of cultures were performed,re-trograde contamination of drainage bag outlets was observed dynamically.Results Retrograde contamination rate of drainage bag outlets of anti-reflux group was significantly lower than common group(7.7% vs 46.0%,P=0.000);suspended group was significantly lower than ground-touching group(17.9% vs 35.8%,P=0.000). Retrograde contamination rates of outlets of drainage bags filled with different properties of liquid were as follows:urine (54.3%)>5% glucose solution(34.5%)>glucose normal saline(24.3%)>0.9% normal saline(10.8%)>ste-rile water(10.5%),pairwise comparison showed a significant difference(P=0.000).The initial occurrence time of contamination in anti-reflux group and common group was on the 13thday and 7thday respectively,two group was significantly different on the 7thday(P=0.041). There was a medium intensity correlation between the types of drainage bags and liquid properties(PearsonC=0.5).Conclusion Different types of drainage bags,retention time,and liquid property can impact retrograde contamination of drainage bag outlets,regular urine culture during the use of drainage bags should be paid attention in clinical practice,so as to use antimicrobial agents rationally and guide replacement time of drainage bags.

OBJECTIVETo study the value of prenatal ultrasound in the diagnosis of fetal malformations.

METHODSWe retrospectively analyzed the clinical data of 993 cases of neonates and induced babies with malformations who were labored in our hospital from January 1999 to October 2006.

RESULTSThe incidence rate of fetal malformation was 22.5 per thousand in our study group. The detection rate of prenatal ultrasound was 79.02% (1 062/1 344), among which the detection rate of the severe malformations (87.58%, 860/982) were significantly higher than that of the minor malformations (55.80%, 202/362) (P < 0.005). The false negative rate was high for the extremity malformations (39.46%) and facial malformations (31.91%), especially the acrosclerodermas, simple cleft palates, and ear deformities.

CONCLUSIONPrenatal ultrasound is sensitive for fetal severe malformations, while the detection rate is low for fetal minor malformations.
