Objective To analyze the characteristics of of organochlorine pesticides(OCPs) residues in the soil of the suburbs of Guangzhou.Methods In Baiyun,Conghua,Zengcheng,Panyu,Nansha,surface soil(0-20 cm) samples of vegetable fields,orchard and paddy soil were collected,soil profile(20-40cm,40-60cm) of Baiyun and Panyu were also collected,in Aug,2008.Gas chromatography-electron capture detector method(GC-ECD)was used to determine 17 kinds of organochlorine pesticides.Results The detection rate of 17 kinds of organochlorine pesticides was 90.59% in topsoil,the residue level was 4.19-39.89 ng/g,and the detection rate in profiles soil was 76.70 %,the residue level was 2.35-91.26 ng/g.OCPs residues were mainly HCHs and DDTs.Conclusion Detection rate of organochlorine pesticides is high in soil in the investigated soil and in the 20-40 cm profiles of Baiyun and Panyu,the level of OCPs exceeds the related standard limit,which may have adverse effects on soil environment.

Objective To investigate the effect of acupuncture combined with minimally invasive hematoma aspiration on a rabbit model of brain injury in the acute stage of intracerebral hemorrhage (ICH). Methods A total of 65 healthy New Zealand white rabbits were randomly divided into a sham operation (SO) group, an ICH group,a hematoma aspiration (HA) group, and an acupuncture and hematoma aspiration (AHA) group. Models of ICH were established in the latter three groups. The HA group was treated with minimally invasive hematoma aspiration and the AHA group was treated with both acupuncture and minimally invasive hematoma aspiration. At 6 hours and 1, 3 and 7 days after the ICH models were established, brain water content (BWC) was measured, and the expression of matrix metalloproteinase-9 ( MMP-9 ) in the rabbits' brains was detected by immunohistochemistry. MMP-9activity was detected by gelatin zymography. Results The BWCs of the ICH group, HA group and AHA group rabbits were significantly higher than those of the SO group. The BWCs of the HA group and AHA group animals descended significantly more than those in the ICH group as time went on, especially on the 3rd day in the AHA group. Immunohistochemistry and gelatin zymography showed that the expression and activity of MMP-9 in these test groups decreased with time, especially on the 3rd day in the AHA group. Conclusions Acupuncture combined with hematoma aspiration can reduce injury in the acute stage of ICH, and inhibition of the expression of MMP-9 may be the mechanism.

Object To investigate the features of health related quality of life ( HRQOL) among elderly hypertensive patients with different body mass index (BMI) so s to provide evidence for the health promotion of hypertensive. Methods A cross-sectional survey of health status data from a population of 1281 elderly hypertensive patients from Beijing and 8 provinces of China ( Jiangsu, Anhui, Gansu, Qinghai, Fujian, Jilin, Jiangxi, and Henan) was made in the study. Analysis of variance was applied to compare the differences in HRQOL of elderly hypertensive patients in different BMI categories. Results For the elderly hypertensive patients with low body mass index, the scores of 8 dimensions and scores in physical component summary (PCS) and mental component summary( MCS) of SF-36 were the lowest;except the role-emotional(RE) dimension,the scores of other 7 dimensions,PCS and MCS were significantly different(PF,RP,BP,GH,VT,MH, P<0.01; SF,PCS,MCS, P<0.01). Comparing the scores between any two groups in PCS, the scores of patients with low body mass index were significantly lower than normal weight group (62.30 ± 22. 12 vs72.40 ±20.86, P<0.05) .overweight group (62.30 ± 22.12 vs 74.97 ± 19.20, P<0.05 ) and obese group (62.30 ± 22.12 vs 74.57 ± 19. 22, P < 0.05 ). Comparing the scores between any two groups in MCS,the scores of patients with low body mass index were significantly lower than normal weight group (68. 81 ± 20. 48 vs 74. 70 ± 20.41, P < 0. 05), overweight group (68. 81 ± 20. 48 vs 78.08 ±18.23, P<0.05) and obese group (68.81 ±20.48 vs 78. 69 ± 17.77, P<0.05); the score of normal weight group was significantly lower than the overweight group (74. 70 ±20. 41vs 78. 08 ±18.23, P<0.05). Gender Stratification showed that females with low body mass index had worse HRQOL than males. Conclusion The HRQOL of elderly hypertensive patients with low body mass index is significantly lower than normal weight patients, overweight patients and obese patients, the health promotion of elderly hypertensive patients with low body mass index should be paid more attentions, especially females with low body mass index.

ObjectiveTo analyze the craniocerebrum ultrasonographic images of the infants born by women with hypertension in pregnancy and investigate the effect of hypertension in pregnancy on neonate brain injury and brain development.MethodsTo assess the brain injury and brain development, 106 infants born by women with hypertension in pregnancy (study group) and 200 infants born by women without high risk factors during perinatal period (control group) in the neonatal intensive care unit of First Affiliated Hospital of Harbin Medical University between 2013 and 2014 underwent brain ultrasonography. The abnormal ultrasound images and the constitution of abnormal ultrasound images distribution in two groups were compared. The relationship between the abnormal ultrasound images and the degree of hypertension in pregnancy were analyzed.ResultsThe brain ultrasonographic result of the infants : (1) In the group with hypertension in pregnancy, the abnormal ultrasound images were found in 78 cases (73.6%). For the preterm infants, the solitary abnormality was found in 41 cases (25 cases of cerebral white matter injury, 14 cases of peri-intraventricular hemorrhage and 2 case of brain hypoevolutism) and multiple abnormalities were found in 15 cases; for the full-term infants, the solitary abnormality was found in 17 cases (12 cases of peri-intraventricular hemorrhage, 3 cases of hypoxic-ischemic encephalopathy and 2 case of brain hypoevolutism) and multiple abnormalities were found in 5 cases. (2) In the group without high risk factors, abnormalities were found in 73 cases (36.5 %). For the preterm infants, abnormal ultrasound images were found in 45 cases, including solitary abnormality found in 30 cases (24 cases of cerebral white matter injury, 4 cases of peri-intraventricular hemorrhage and 2 case of brain hypoevolutism) and multiple abnormalities found in 15 cases; for the full-term infants, the abnormal ultrasound images were found in 30 cases, including solitary abnormality found in 24 cases (10 cases of peri-intraventricular hemorrhage and 14 cases of hypoxic-ischemic encephalopathy) and multiple abnormalities found in 6 cases. (3) There were obvious statistical significances between the comparativeness of two groups (χ2=38.119,P<0.001), but there were no statistical significances in the constitution of the abnormal ultrasound images distribution between the two groups (χ2=0.552,P=0.759). (4) There were statistical significances between the comparativeness of the abnormal ultrasound images and the degree of hypertensive disorder complicating pregnancy (P<0.001). ConclusionCraniocerebrum ultrasonography is the first choice to detect and monitor brain abnormal and can provide basis for clinical diagnosis, treatment and intervention at early stage for the infants born by women with hypertension in pregnancy.

To programming one Child's Behavior Problems Computer Screening System (CBPCSS), a series of software for analyzing child behavior individual and group sample. According to the world-famous American ACHENBACH child's behavior checklist, to ensure the screening quality and compatibility of cultures, we revised and standardized the norms of different ages in primary schools and nursery schools in various cities based on the principle of cluster stratified sampling. Then we designed CBPCSS carefully. The system can reliably and rapidly screen an individual child behavior and output the behavior factor curve (appearing in front of the profile). With CBPCSS we can observe the child behavior clearly. It takes twenty times shorter than that of manual screening. On the other hand, CBPCSS has a function of group analysis. The clinical practice proved that CBPCSS could substitute for manual screening completely. It is a powerful tool for social, scientific and pediatric medical workers.
