Objective To explore the relationship of red blood cell distribution width (RDW) with severity and prognosis in children with sepsis. Methods The RDW, clinical features and prognosis of 494 sepsis children were retrospectively ana-lyzed. Results The RDW was increased in 305 sepsis children (61.74%) among whom 49.30%in sepsis group, 60.27%in sever sepsis group and 83.46%in septic shock group. The difference was signiifcant (P<0.001). The mortality of RDW increased children among three groups was 1.89%, 20.45%, 67.57%, and it was signiifcantly different (P<0.001). The rates of increased RDW was 56.15%in 374 survived cases and 79.17%in 120 died cases, and the difference was signiifcant (P<0.001). Pediatric critical illness score (PCIS) was negatively correlated with RDW (P<0.001), while mortality was positively correlated with RDW (P<0.001). Conclusions The rate of increased RDW is high in children with severe sepsis and septic shock and the level of RDW is closely related to the prognosis of patients.

Objective To explore the impact of iodine nutrition on pregnant women before and after adjusting the iodine content in iodine salt.Methods Twelve counties (areas,cities) in Hangzhou were divided into urban,suburban and rural areas before and after adjusting the iodine content of salt.One survey spot was selected in each district and one hundred pregnant women were selected;family salt and urinary samples of each pregnant woman were collected.The levels of salt and urinary iodine were measured by the methods of picric sodium thiosulfate titrimetric (GB 13025.7-2012) and spectrophotometer (WS/T 107-2006),respectively.Results One thousand two hundred and thirty-nine and one thousand two hundred and thirty-three household salt samples were collected before and after adjusting the iodine content in iodine salt.The median of salt iodine of pregnant women (23.30 mg/kg) before adjusting the iodine content in iodine salt was lower than that after adjusting the iodine content in iodine salt (30.09 mg/kg,x2 =-4.71,P ＜ 0.01).The iodine salt coverage rate and the consumption rate of qualified iodized salt after adjusting the iodine content in iodine salt [93.92％ (1 158/1 233),93.84％ (1 157/1 233)] were higher than those before adjusting the iodine content in iodine salt [91.85％ (1 138/1 239),91.37％ (1 132/1 239),x2 =4.01,5.51,all P ＜ 0.05].The iodine salt coverage rate and the consumption rate of qualified iodized salt in urban and suburb areas after adjusting the iodine content in iodine salt [99.42％ (510/513),100.00％ (203/203),97.86％ (5021513),100.00％ (203/203)] were higher than those before adjusting the iodine content in iodine salt [86.71％ (450/519),98.00％ (196/200),77.26％ (401/519),85.00％ (170/200)],but the iodine salt coverage rate and the consumption rate of qualified iodized salt in rural area before adjusting the iodine content in iodine salt [94.62％ (492/520),86.92％ (452/520)] were higher than those after adjusting the iodine content in iodine salt [85.69％(443/517),76.98％ (398/517),x2=64.22,2.32,100.02,32.90,23.31,17.33,all P ＜ 0.05].One thousand two hundred and thirty-four and one thousand two hundred and thirty-one household urine samples were collected before and after adjusting the iodine content in iodine salt.The median of urinary iodine (MUI,114.80 μg/L) of pregnant women after adjusting the iodine content in iodine salt was lower than that before adjusting the iodine content in iodine salt (168.60 μg/L,x2 =36.92,P ＜ 0.01).The MUIs of pregnant women in urban,suburban,and rural areas (171.30,170.20 and 162.40 μg/L) before adjusting the iodine content in iodine salt were higher than those after adjusting the iodine content in iodine salt (101.00,149.48 and 119.90 μg/L,x2 =-7.78,-2.63,-6.28,all P ＜ 0.01).The differences of urinary iodine between groups were statistically significant in urban,suburban and rural areas after adjusting the iodine content in iodine salt (x2 =32.86,P ＜ 0.01),the MUI of pregnant women in urban areas was lower than those in the suburban and rural areas (x2 =6.70,8.13,all P ＜ 0.05).Conclusions After adjusting the iodine content of salt in Hangzhou,the iodine-nutrition level of pregnant women is decreased.But the consumption rates of qualified iodized salt and the MUIs in urban,suburb,rural areas are different,so the coverage of iodized salt at household level needs to be enhanced and the health education should be highlighted.

Objective To observe the effect of autophagy on paclitaxel-induced CaSki cell death through the regulation of the expression of autophagy gene Beclin1, and to explore the interaction and relationship between autophagy and apoptosis. Methods Eukaryotic expression vector pcDNA3.1-Beclin1 and RNA interference vector pSUPER-Beclin1 were transfected into human cervical cancer CaSki cells in vitro and screened for stable expression cell lines. The formation of autophagic vacuoles was observed with an electronic microscope. The expression of Beclin1 and LC3 was measured by Western blot. After being treated with paclitaxel, the change of cell proliferation was assessed by MTT assay, the percentage of apoptotic cells and autophagic cells were analyzed by flow cytometry. Results A lot of autophagic vacuoles were observed in pcDNA3.1-Beclin1 cells by electronic microscopy. Beclin1 and LC3 protein expression was up-regulated in CaSki cells transfected with pcDNA3.1-Beclin1, and was inhibited in cells transfected with pSUPER-Beclin1. MTT assay revealed the survival rate of CaSki cells was significantly decreased after being transfected with pcDNA3.1-Beclin1. After being treated with paclitaxel, the percentages of apoptotic cells and autophagic cells were both increased in pcDNA3.1-Beclin1 group compared with that of the blank control group especially the increase of apoptosis was particularly evident. Conclusion Autophagy and apoptosis have different roles in the process of paclitaxel-induced cervical cancer CaSki cell line death. Overexpression of Beclin1 in CaSki cells may enhance the apoptosis induced by paclitaxel.

Objective:To investigate the functional status of dendritic cells(DCs)in oral leukoplakia(OLK)tissues.Methods:The expression of DC-specific markers CD1 a,CD209,CD1 23 and CD83 in 20 cases of OLK with abnormal dysplasia,1 0 with simple dys-plasia and 1 0 of normal oral mucosa tissues was examined by immunohistochemistry.Results:CD1 a and CD209 positive DCs were found in all cases.More CD1 a positive Langehans cells(LCs)in lamina propria were found in OLK with abnormal dysplasia than in normal o-ral mucosa and OLK with simple dysplasia(P <0.01 ).A great mount of CD209 positive stromal DCs were recruited in OLK.There was no CD83 positive and CD1 23 positive cell in normal oral mucosa,however,CD83 positive mature DCs and CD1 23 positive plasmacytoid DCs(PDCs)were observed in OLK(P <0.01 ).Conclusion:OLK is characterized by the recruitment of different subsets of DCs,the different DC subsets may play an important role in the development of OLK.
