Objective To understand the effects of environmental pollution on blood lead levels of children.Methods The blood lead levels of605children aged2-7in6urban districts of Harbin and307children aged2-7in Jixi were deter-mined by graphite furnace atom absorption spectrophotometry during the period from April to June in1999.Results The data on blood lead levels of children in two cities showed both positive skewness distribution.The geometric means of blood lead lev-els of children were0.354?mol/L in Harbin and0.441?mol/L in Jixi,the medians were0.369?mol/L in Harbin and0.440?mol/L in Jixi,the values of P 95 were1.575?mol/L in Harbin and1.304?mol/L in Jixi.The children with blood lead levels of≥0.483?mol/L accounted for44.5%of total observed in Harbin and44.9%in Jixi.Conclusion Environmental lead pollution had coused potential adverse effects on preschool children health.

Objective To understand the influential factors for blood lead level of children in Harbin.Methods The lead level in the air,dust,vegetables and the blood of 605 children aged 2-7 years were determineded and family fitment,fuel combustion,the food consumption were investigated.Results The lead contents of air,dust in pollutant areas [(2.037?0.455)?g/m3,(84.000?0.015)mg/kg] were higher compared with the control areas[(1.017?0.595)?g/m3,(72.000?0.025)mg/kg],the differences were significant(P

Objective To analyze the risk factors of early renal damage in children with Henoch Schonlein purpura(HSP).Methods The clinical data of 196 children with HSP admitted to our hospital from April 2012 to January 2016 were analyzed retrospectively.They were divided into the renal damage group and non-renal damage group within 90 d after confirmed diagnosis.The related clinical data such as serum immunoglobulin and urinary microalbumin were compared between the two groups,and the risk factors of early renal damage in children with HSP were screened.Results There were significant differences between the two groups on age,joint symptoms,recurrent purpura,persistent rash,gastrointestinal bleeding and abdominal pain(with χ2 or t of 11.345,16.223,11.275,43.211,12.592,17.771,P<0.05).The white blood cell count,platelet count,immunoglobulin A(IgA) level and urinary albumin level also showed significant differences between the two groups(t=33.750,60.442,9.451,8.458,P<0.05).The multivariate regression analysis showed that the independent risk factors for early renal damage in children with HSP included age(OR=2.703),recurrent purpura(OR=2.721),persistent skin rash(OR=1.782),gastrointestinal bleeding(OR=11.472),abdominal pain(OR=2.046),IgA level(OR=1.221) and urine microalbumin(OR=3.214).Conclusion Age,recurrent purpura,persistent skin rash,gastrointestinal bleeding,abdominal pain,IgA level and urine microalbumin are closely related to early renal damage in children with HSP.

Objective To investigate the effects of different head positions during operation on wake-up time and quality among ankylosing spondylitis (AS) patients with thoracolumbar kyphosis following pedicle subtraction osteotomy (PSO).Methods Sixty patients were included in this study.All of them,treated with intravenous anesthesia,took the bow-prone position.The patients were randomly divided into two groups:the experiment group where the head was elevated by 10° and the control group where the head was not elevated.The two groups were compared in respect of wake-up time and quality of wake-up test.Results The wake-up time in the experiment group was significantly shorter as compared to that of the control group (1 3.7±2.0 min vs.24.2±2.7min,P＜0.05).The wake-up quality was better as well.Conclusion Elevation of the head by 10° can shorten wake-up time and improve the quality of wake-up test during the procedure of PSO for AS patients with thoracolumbar kyphosis.

Objective:This study aimed to investigate the expressions of EZH2 and Ki-67 in the salivary adenoid cystic carcino-ma (SACC) of humans and their correlation. Methods:A total of 42 cases of SACC tumor tissues and 5 cases of normal tissues were considered to determine the expressions of EZH2 and Ki-67 by immunohistochemistry. The relationship and correlation of such expres-sions with the clinicopathological characteristics were also analyzed. Results:The expression of EZH2 was notably higher in SACC than in normal tissues (P<0.05). EZH2 expression was detected in 66.67%(28/42) of the tumor tissues. This expression was correlated with pathological grade and clinical stage. By contrast, EZH2 expression did not correlate with gender, age, and localization. EZH2 was not expressed in normal tissues. The incidence of EZH2 expression in the Ki-67 positive group was 75.76%(25/33) and the incidence in the Ki-67 negative group was 33.33%(3/9). The difference between the two groups was statistically significant (P<0.05). Conclu-sion:The increased expression of EZH2 in SACC was related to tumor proliferation. EZH2 may participate in tumor cell proliferation via cell cycle management.
