ObjectiveTo observe the clinical features, complications, and prognosis of subarachnoid hemorrhage (SAH) in the aged. Methods132 old cases were analyzed retrospectively. Results56.8% of patients complained headache as the main symptoms, 43.2% with dizziness or vertigo, 40.1% with disturbance of consciousness, 70.5% with negative of meningeal irritation sign. The most common cause is the aneurysm. The mortality was more in those complicated with hypertension. ConclusionSAH in the old characterized variable clinical manifestations, no special signs, half of them with good prognosis.

Graves′disease ( GD) is an organ-specific、autoimmune and hyperthyroid thyroid disease closely related to the TSH receptor antibody ( TRAb) .Oxygen free radicals and the oxidative damage caused by these are closely related to the development and progression for GD .Researches on oxidative stress are providing novel therapeutic targets of GD .

Objective To investigate the level of serum vascular endothelial growth factor and soluble vascular endothelial growth factor receptor-1 in patients with pre-eclampsia and eclampsia.Methods Serum vascular endothelial growth factor and soluble vascular endothelial growth factor receptor-1 in peripheral venous blood were determined by ELISA in patients with pre-eclampsia(n=9),severe pre-eclampsia(n=10) and eclampsia(n=5)(total eclampsia n=24) and healthy controls(n=18).Results Patients with pre-eclampsia and eclampsia had higher level of serum sVEGFR-1(pre-eclampsia:58?7 mg/L,severe pre-eclampsia:82?15 mg/L,eclampsia:96?13 mg/L vs control:11?3 mg/L,P

As a first-grade carcinogen,the dioxin had caused huge food safety and political crisis as well as economic losses, and posed unacceptable health risk to consumers in some European countries.The international community has commonly shown great concerns for the issue.Three specific researches on the dietary exposure risk of Australian consumers posed by dioxin have been undertaken in Australia since 2001.Reliable results of the research have been obtained.This paper outlined origin, development and the status of the Australian dioxin dietary exposure assessment.Prospecting for developing the dioxin dietary exposure assessment in China has been put forward based on the discussion of the Australian experience.

Objective To understand the hygienic situation of drinking water in the rural areas in the river system of the Yangtze and Huaihe in Jiangsu Province,and to provide the scientific evidence for improving the quality of drinking water. Methods From January to October in 2007,according to the guideline of drinking water quality monitoring in the rural areas,in the river system of the Yangtze and Huaihe in Jiangsu Province,in 53 counties (cities),the drinking water quality of the central water supply and the non-central water supply was investigated. Results From the result of comprehensive evaluation,the eligible rate of drinking water in the rural areas in the river system of the Yangtze and Huaihe in Jiangsu Province was 41.34%. As for residual chlorine the eligible rate was 49.64%,as for total coliform group it was 79.69%,as for total number of bacteria it was 88.78%,as for the turbidity it was 85.75%,as for fluoride it was 92.63%,as for the other indexes it was above 95%. Compared with the Huaihe river system,the fluoride content in the Yangtze river system was lower,total coliform group,turbidity and manganese content were higher (P

[Summary] The human thyroid epithelium cells were obtained from normal para-adenoma tissues of patients with thyroid adenoma or nodule.Cells were treated with 1 000 IU/ml interferon-γ (IFN-γ) + 10 ng/ml tumor necrosis factor-α (TNF-α),1 mmol/L N-acetylcysteine (NAC),1 mmol/L glutathione (GSH),and 10 μmol/L dexamethasone (DEX) respectively.Malondialdehyde(MDA),glutathioneperoxidase(GSH-Px),and superoxidedismutase(SOD) levels in the cell supernatant were measured.The results showed that IFN-γ+TNF-α significantly increased MDA level (P＜0.05) while decreased GSH-Px and SOD levels (P＜0.05).After NAC,GSH,and DEX intervention,MDA levels all were significantly lowered (all P＜0.05) while GSH-Px and SOD levels were significantly increased compared with IFN-γ+TNF-α stimulation(all P＜0.05).These results suggest that IFN-γ and TNF-α can induce oxidative stress in the human thyrocyte,and this effect is antagonized by NAC,GSH,and DEX via increasing GSH-Px,SOD activity and decreasing MDA content.

?AIM:To compare the corrected vision and improvement of visual quality after wearing rigid gas permeable corneal lens ( RGPCL) or spectacles in aphakic patients.?METHODS: We selected 29 aphakic patients ( 29 eyes ) caused by different reasons wearing RGPCL and spectacle.The corrected vision, eye condition and visual quality were observed and all patients were followed up for 6mo.? RESULTS: RGPCL was better than spectacle on corrected vision (P<0.05).The patients who wore RGPCL for long had no corneal complications reported. The patients who wore RGPCL had better subjective visual quality than those wore spectacle.?CONCLUSION: RGPCL is a good choice for correcting high myopia and astigmatism for aphakic patients.The patients'compliance is good. Wearing RGPL long has high safety for patients'ocular surface.

Objective To explore the clinical manifestation of stroke caused by central nervous system vasculitis (CNSV). Methods 49 patients who suffered from stroke by CNSV were reviewed retrospectively. Results Among the 49 patients, 5 were intracerebral hemorrhage, 15 were ventricular hemorrhage, 7 were subarachnoid hemorrhage and 22 were cerebral infarction; the mean of age was (26.0±12.7) years old. Conclusion The clinical manifestation of stroke caused by CNSV is variform, and usually happens in young age. CNSV should be considered as the cause of stroke in adolescent.

Objective To investigate the application value of multifunctional dynamic flat panel X-ray detector in intravenous pyelography.Methods Total 540 patients with intravenous pyelography were divided into multifunctional dynamic flat panel X-ray detector group (300 cases) and conventional flat panel X-ray detector group (240 cases) by random digits table method.Image quality,radiation dosage and examination time were analyzed and compared between the two groups.Results There was no statistical difference between the two groups in image quality (P ＞ 0.05).The examination time and radiation dosage was (25.5 ± 8.2) min and (12.5 ± 6.8) mAs respectively in multifunctional dynamic flat panel X-ray detector group and (39.2 ± 12.1) min and (23.6 ± 7.6) mAs in conventional flat panel X-ray detector group.The differences had statistical significance (P ＜ 0.01).Conclusions Multifunctional dynamic flat panel X-ray detector in intravenous pyelography can provide lower radiation dose,shorter examination time and higher image quality.It has obvious advantages in urography.

Objective To determine the relationship between acceptance of disability and posttraumatic stress response in patients with brachial plexus injury. Methods Total 160 patients with brachial plexus injury were recruited and investigated with the Impact of Event Scale-Revised (IES-R) and the Acceptance of Disability Scale (ADS). Results The total score of ADS was (79.07±11.99) which showed medium level of acceptance of disability. The total score of IES-R was 4-66 (33.51±14.41), which showed that most of the patients suffered from posttranmatic stress response. Significantly negative correlation was found between acceptance of disability and posttraumatie stress response(r=-0.480, P<0.001). Conclusions Nurses should pay more attention to the acceptance of disability and posttranmatic stress response in patients with brachial plexus injury, and provide appropriate health education and effective psychological intervention to improve the patients' mental health and quality of llfe.
