Objective To understand the current status and related factors of unexpected injuries during hospitalization in old patients in Shaoxing city. Methods By way of convenient sampling methods, 850 old patients aged over 65 years were chosen from five of grade 3 hospitals in Shaoxing city. The status and consequence of unexpected injuries during their hospitalization in past one year were retrospectively investigated with face to face questionnaire at patients home. Results The occurrence of unexpected injuries in 850 hospitalization old patients were 54(6.35%) during their hospitalization in past one year. The occurrence rate in female (9.27%) was significantly higher than that in male (4.25%) (?2=7.57, P

Objective To introduce clinical diagnostic specificity of hepatocellular carcinoma (HCC) with serum AFP level in 21*!?g/L to 200*!?g/L. Methods Making a literature summarizaton based on the papers review.Results and Conclusions (1) The AFP level more than 20*!?g/L can be used as a diagnostic criteria of HCC when existing liver space occuping lesion (SOL). (2) The clinical diagnostic criteria using AFP level more than 20 ?g/L instead of more than 200 ?g/L would be helpful to avoid misdiagnosis of HCC with the AFP level in 21 ?g/L to 200 ?g/L. (3) The Combination of AFP level more than 20 ?g/L with ultrasonography, CT scanning would have higher sensitivity and specificity than single diagnostic method.

ObjectiveTo investigate the value of low positive AFP level for the diagnosis of hepatocellular carcinoma (HCC) when a space occuping lesion (SOL) was already identified in the liver.MethodsUsing randomized controlled clinical trial,a clinical epidemiological analysis was made based on the result of surgery and pathology proven hepatic SOL of 2?878 cases admitted from January 1993 to June 2001.In this series,there were 2?362 HCC cases, among which 424 HCC cases were with a low positive AFP level(between 21 and 200??g/L) which constitutes the basis of our analysis.ResultsIn HCC and non HCC groups,the sensitivity,specificity and positive predictive value were 69 9%(1?650/2?362) vs.8 9%(46/516) ( P

Aim To observe the protective effects of epigallocatechin gallate(EGCG)on cortical neurons of embryonic mice the injury by FeSO4/H2O2 in vitro.Methods The cell injury model was established with FeSO4/H2O2 for 24 h.The process of the growth and morphology of the neurons were observed under phase contrast microscope in vitro.The cell survival was analyzed using colormetric neutral red assay.The cortical neuronal viability was analyzed using MTT assay.TBARS method was performed to detect the levels of Malondialdehyde(MDA).The composing capacity of total protein was measured by BCA method.Results As compared with FeSO4/H2O2,EGCG enhanced the mouse cortical neuronal survivality and viability,decreased the levels of MDA and increased the composing capacity of total protein.Conclusion EGCG exerted protective effects on cortical neurons the injury induced by FeSO4/H2O2,which may be related to free radial scavenging activity and lipid peroxidation process being inhabited.

Objective To research the indoor air pollution in offices induced by decoration and its health effects. Methods According to the completed time, the offices were divided into 6 groups (2 month group, 2-4 month group, 5-8 month group, 9-11 month group, 12-18 month group, over 5 year group). The concentration of indoor air pollutants was determined and 617 people from the decorated offices were randomly selected to finish the questionnaires on health. Results The over standard rate of formaldehyde, benzene and ammonia in indoor air was the highest in 2 month group, 100%, 87.3%, 83.9% respectively. The concentration of indoor air pollutants decreased as the time went on, about one year after decoration, the concentrations were lower than the standard limits (GB/T 18883-2002). The adverse response rate of the staff members in offices decorated group (76.4%) was significantly higher than that in the control group (30.9%) (P

Objective　To introduce clinical diagnostic specificity of hepatocellular carcinoma (HCC) with serum AFP level in 21μg/L to 200μg/L. Methods　Making a literature summarizaton based on the papers review.Results and Conclusions　(1) The AFP level more than 20μg/L can be used as a diagnostic criteria of HCC when existing liver space occuping lesion (SOL). (2) The clinical diagnostic criteria using AFP level more than 20 μg/L instead of more than 200 μg/L would be helpful to avoid misdiagnosis of HCC with the AFP level in 21 μg/L to 200 μg/L. (3) The Combination of AFP level more than 20 μg/L with ultrasonography, CT scanning would have higher sensitivity and specificity than single diagnostic method.

Objective To investigate the real situation of the burden of the caregivers who take care of patients with spinal cord injury.Methods Using phenomenological research methods of qualitative study,information of 15 family caregivers of patients with spinal cord injury were collected through semi-structured interviews in Jiangxi province,and data were analyzed with Colaizzi 7-step analysis method.Results Four themes were summarized:weak social support system,heavy economic burden,insufficient care ability,mental and physical exhaustion; mental and physical exhaustion concluded three sub-themes:burnout,lifestyle changes,sad/helplessness.Conclusions Care burden of caregivers of patients with spinal cord injury includes four aspects:social,physical,psychological,and less caring capacity.Care workers should be concerned about the health status of the caregivers,give targeted care intervention,so that caregivers can be adapted to the caregivers' role,maintain and promote a high level of health of the patients and their families.

Objective To investigate the feasibility of achieving consistent image quality with dose reduction technology in lumber spine MSCT examination with Z-axis automatic tube current modulation (ATCM). Methods Forty-eight patients diagnosed as lumber intervertebral disc protrution scanned twice by MSCT before and after interventional operations with the same coverage from third lumbar vertebra to first sacral vertebra. The first scan (FM) was with fixed tube current of 320 mAs. The follow-up scan was with ATCM with noise index (NI) of 12.0 HU. At the levels of L3-4, L4-5 and 15-S1, image quality, image noise and radiation dose were measured and analyzed. Image quality and radiation dose were compared by paired t-test and the image noise was compared by ANOVA test. Results The dosage of the ATCM had a 31.3% reduction compared with FM, the average DLP was(187.9±66.4)mGy·cm and(273.4±45.4) mGy·cm respectively, where t = 8.205, P < 0.05. The average noise and their deviations for the FM group were (9.8±2.4) HU,(9.9±2.4) HU, and (11.5±3.2) HU at level of L3-4, L4-5, 15-S1, respectively. With ATCM, the average noise was(12.0±0.8) HU, (11.7±0.6) HU, and (11.7±1.4) HU, respectively. There was statistical difference between the two groups (F = 23.31, P < 0.05). The image quality scores for the FM group were (4.7±0.3), (4.5±0.2), (4.5±0.2) and showed no statistical difference to ATCM group (4.6±0.3), (4.5±0.2), (4.5±0.2) at level of L3-4, L4-5, L5-S1, respectively, where t = 1.000, P > 0.050 Conclusion ATCM technique with the noise index setting at 12.0 HU can achieved a 31.3% dose reduction while keep the consistent image quality for lumbar spine MSCT study.
