1.How to establish the hospital information system security policies.
Chinese Journal of Medical Instrumentation 2008;32(2):124-130
It is important to establish the hospital information system security policies. While these security policies are being established, a comprehensive consideration should be given to the acceptable levels of users, IT supporters and hospital managers. We should have a formal policy designing process that is consistently followed by all security policies. Reasons for establishing the security policies and their coverage and applicable objects should be stated clearly. Besides, each policy should define user's responsibilities and penalties of violation. Every organization will need some key policies, such as of information sources usage, remote access, information protection, perimeter security, and baseline host/device security. Security managing procedures are the mechanisms to enforce the policies. An incident-handling procedure is the most important security managing procedure for all organizations.

Objectives To investigate the relationship between fluorosis polymorphisms in collagen type Ⅰ alpha 2 (COL1A2) and osteocalcin (OC) gene, and serum calciotropic hormone levels. Methods The children between 8 and 12 years of age in Kaifeng and Tongxu cities of Henan Province were chosen to be the object of observation. Accoding to situation of dental fluorosis, they were divided into three groups: dental fluorosis group, non-dental fluorosis group from high fluoride areas, and control group form the control areas. The Pvu Ⅱ and Rsa Ⅰ markers of COL1A2 gene as well as HindⅢ marker of OC gene were genotyped by PCR-RFLP procedure. Calcitonin and osteocalcin levels in serum were measured using radioimmunassays. Results The frequency distribution of COL1A2 PvuⅡ genotype was pp 49.3%(37/75), Pp 32.0%(24/75), PP 18.7%(14/75) in children with fluorosis; pp 43.5% (30/69), Pp 52.2% (36/69), PP 4.3%(3/69) in children without fluorosis from high fluoride areas; and pp 43.8% (42/96), Pp 40.6% (39/96), PP 15.6% (15/96) in the children without fluorosis from control areas respectively. Childrens with the homozygous genotype PP of COL1A2 Pvu Ⅱ had a significantly increased risk of dental fluorosis(OR=4.85, 95%CI: 1.22-19.32) compared to children with the homozygous genotype pp in anendemic fluorosis area. The frequency distribution of COLIA2 Rsa Ⅰ genotype was rr 50.7% (38/75), Rr 36.0% (27/75), RR 13.3%(10/75) in children with fluorosis; rr 46.4%(32/69), Rr 46.4%(32/69), RR 7.2%(5/69) in children without fluorosis from high fluoride areas, and rr 45.8% (44/96), Rr 45.8% (44/96), RR 8.3% (8/96) in the children without fluorosis from control areas respectively. There were no significant differences in the three groups (P>0.05). The frequency distribution of OC Hind Ⅲ genotype was hh 48.0% (36/75), Hh 34.7% (26/75), HH 17.3% (13/75) in children with fluorosis; hh 43.5% (30/69), Hh 43.5% (30/69), HH 13.0% (9/69) in children without fluorosis from high fluoride areas, and hh 47.9%(46/96), Hh 40.6%(39/96), HH 11.5%(11/96) in children without fluorosis from control areas respectively. There were no significant differences in the three groups (P>0.05). Additionally, fluoride levels in urine and OC levels inserum were found to be significantly lower in controls from non-endemic areas compared to cases(P<0.05). However, the differences in urine fluoride and serum OC levels were not observed when cases were compared to controls from high fluoride areas(P>0.05). Conehlsions This study provides the evidence of an association between polymorphisms in the COL1A2 gene with dental fluorosis in populations exposed to high fluoride. There were no correlation between OC Hind Ⅲ genotype and the dental fluorosis.

OBJECTIVETo explore the influence of water fluoride exposure on reproductive hormones in female.
METHODSCross-sectional study was conducted in seven villages of a county in Henan province by using simple random sampling including high fluoride area, defluoridation project area and control area on April, 2011 based on the preliminary study results of fluoride concentration in drinking water. Women who were born and growth or lived in the village at least 5 years and aged 18-48 years old were recruited using cluster sampling. They were divided into high fluoride group (HFG, 116 subjects), defluoridation project group (DFPG, 132 subjects) and control group (CG, 227 subjects) in accordance with the above areas. All subjects accepted questionnaire and physical checkup. Fasting blood and morning urine samples were collected. The concentration of fluoride in urine was determined by fluoride ion selective electrode method. The serum level of GnRH was detected using enzyme linked immunosorbent assay (ELISA). The serum level of luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone (T), estradiol (E2) were determined by chemiluminesence immunoassay (CLIA).
RESULTSThe average age was (39.44 ± 7.34), (38.84 ± 8.03), (37.45 ± 7.70) years old in female from DFPG, HFG and CG respectively, there were no significant differences among the three groups (F = 3.02, P = 0.05). The urine fluoride levels were (1.34 ± 1.07), (2.59 ± 1.57), (0.92 ± 0.46) mg/ml in female from DFPG, HFG and CG respectively, there was a significant difference among three groups (F = 105.38, P < 0.01). No significant differences were observed of serum GnRH, LH, T, FSH and E2 among three groups in follicular phase (P > 0.05). The serum levels of E2 in Ovulatory period were 67.73, 58.09, 84.96 pg/ml in female from DFPG, HFG and CG respectively. It was lower in HFG than that in CG (H = 4.00, P < 0.05). The serum levels of T in Ovulatory period were 0.55, 0.45, 0.55 ng/ml in female from DFPG, HFG and CG respectively. It was lower in HFG than that in DFPG (H = 6.47, P < 0.05), but no significant difference was observed between HFG and CG (H = 2.41, P > 0.05). The serum levels of GnRH in Luteal phase were 24.09, 20.16, 23.50 ng/ml in female from DFPG, HFG and CG respectively. It was lower in HFG than that in DFPG (H = 14.14, P < 0.05) and CG (H = 12.53, P < 0.05). The serum level of E2 in luteal phase were 81.47, 64.60, 74.55 pg/ml in female from DFPG, HFG and CG respectively. It was lower in HFG than that in DFPG (H = 5.69, P < 0.05). As for LH, FSH and T, no significant differences were observed among the three groups (P > 0.05 respectively). The abnormal rates of E2 level were 22.73 (30/102), 37.93 (44/72), 20.26 (46/181) in female from DFPG, HFG and CG respectively. The E2 abnormal rate in female from HFG was higher that from DFPG (χ(2) = 6.82, P < 0.05) and CG (χ(2) = 12.38, P < 0.05).
CONCLUSIONFluoride exposure may influence reproductive hormones in female, especially in ovulatory and luteal phase of menstrual cycle.

OBJECTIVETo assess the medical community's awareness and practice regarding delirium in the intensive care unit (ICU).
METHODSOne hundred and ten predesigned questionnaires were distributed to ICU practitioners in the affiliated hospitals of Zhejiang University.
RESULTSA total of 105 valid questionnaires were collected. Totally, 55.3% of the clinicians considered that delirium was common in the ICU. Delirium was believed to be a significant or serious problem by 70.5% of respondents, and under-diagnosis was acknowledged by 56.2% of the respondents. The incidence of ICU delirium is even more under-estimated by the pediatric doctors compared with their counterparts in adult ICU (P less than 0.05). Primary disease of the brain (agreed by 82.1% of the respondents) was believed to be the most common risk factor for delirium. None of the ICU professionals screened delirium or used a specific tool for delirium assessment routinely. The vast majority (92.4%) of respondents had little knowledge on the diagnosis and the standard treatment of delirium.
CONCLUSIONSAlthough delirium is considered as a serious problem by a majority of the surveyed ICU professionals, it is still under-recognized in routine critical care practice. Data from this survey show a disconnection between the perceived significance of delirium and the current practices of monitoring and treatment in ICU in China.

OBJECTIVETo initially evaluate the application of artificial vertebra of n-HA/PA66 in anterior reconstruction of lower cervical spine fracture and dislocation.
METHODSIn this study, 84 patients with lower cervical spine fracture and dislocation received anterior cervical discectomy, spinal canal decompression or subtotal corpectomy, spinal canal decompression and reconstruction by n-HA/PA66 composite artificial vertebral body combined with plate instrumentation. Neurological function was followed up by improvement rate of Frankel and situations of the supporting body was observed by X ray and 3D-CT in 3, 12, 24 months postoperatively. The intervertebral height, physical arc (reflected by Cobb angle) and the locations and fusion rate of the supporting body were assessed in order to evaluate the stability of the cervical spine and alignment improvements.
RESULTSAll the patients underwent operation successfully and were followed up for 6 to 24 months with an average of 12 months. The preoperative symptoms were improved to varying degrees. Imaging studies showed that in all cases graft fusion were achieved, and cervical alignments, intervertebral height, cervical spine stability and the locations of the artificial vertebral body were well maintained. No displacement and subsidence of the artificial vertebral body occurred. Postoperative immediate intervertebral height (2.4 ± 0.2) cm, preoperative intervertebral height (1.9 ± 0.1) cm, comparisons of the two groups was statistically significant (q = 2.48, P < 0.001). The immediate, 3 month, 1 year, 2 year period follow-up group intervertebral height was not statistically significant (P > 0.05). Preoperative Cobb angle was 9.8° ± 1.2°, postoperative immediate Cobb angle was 16.6° ± 1.2°, comparisons of the two groups was statistically significant (q = 14.25, P < 0.001). The immediate, 3 month, 1 year, 2 year period follow-up group Cobb angle was not statistically significant (P > 0.05).
CONCLUSIONSn-HA/PA66 artificial vertebral body can provide early cervical spine support and stability and effectively maintain the biological alignment and cervical intervertebral height. It has high rate of graft fusion and is convenient to observe by X-ray. Therefore, n-HA/PA66 can be taken as an ideal graft for anterior lower cervical spine fracture and dislocation operation, but further follow-up study is still required to evaluate the long-term effects.
