ObjectiveTo study the characteristics of the relationship between injury and disease in foren-sic identification cases of cervical trauma with cervical vertebra degeneration, and to explore the prob-lems about how to identify the participation rates of injury and disease using the clinical information, forensic examination and imaging examination.MethodsSeventeen forensic identification cases of cervi-cal trauma with cervical vertebra degeneration were collected. The age distributions, injury formations, injury severities and imaging findings of these cases were analyzed and the relationship between injury and disease was evaluated comprehensively.ResultsMiddle-aged and elderly were common in 17 cases and every case was involved with intervertebral disc herniation. The main reasons of injuries were hy-perextension. The degree of injury severity and vertebra degeneration were graded according to the imag-ing findings. The participation rates of injury and disease were also calculated comprehensively.Conclu-sionThe forensic identification cases of cervical trauma with cervical vertebra degeneration should be evaluated with clinical information, forensic examination and imaging finding.

Objective To investigate the relation between the formaldehyde content of newly decorated houses and the time after decoration finished, which will offer an important reference to housing corporations and household. Methods The formaldehyde contents of newly decorated houses in Maoming were analyzed by colorimetry, Mar-Aug, 2003. Results The formaldehyde content in house A, in which the floor was compound floor boards, was higher than that in house B, in which the floor was wearable bricks. The formaldehyde content was not only related to the time after decoration finished, but also to the air temperature. After decoration finished, it must take half a year that the content of formaldehyde would meet the national standard limit. In consecutive testing, it was found that the content of formaldehyde would increase a little as the air temperature increased. Conclusion It must be attached importance to the formaldehyde content in the house floored with compound boards. It will need 6 months at least that the content of formaldehyde meet the requirement of the national standard after the newly house decoration.

Liver failure is a clinical syndrome characterized by serious liver damages.It can results from a variety of causes,and the prognosis is usually poor.How to objectively assess the severity of liver failure and accurately predict the prognosis are the hot spots and challenges in studies on liver failure.The assessment criteria and models widely used clinically include:Child-Turotte-Pugh (CTP) score,acute physiology,age and chronic health evaluation(APACHE) Ⅱ/Ⅲ score,King's College Hospital (KCH) criteria,sequential organ failure assessment (SOFA) score and model for end-stage liver disease (MELD) score.Besides,more factors are identified as potential markers in prognosis assessment.This paper reviews the importance of prognosis assessment in liver failure,and introduces current and new systems or markers in prognosis assessment.

A spectrophotometric method for the determination of trace amounts of mercury (Ⅱ ) was described based on the formation of a complicated ion-association complex of Hg (Ⅱ )-Ⅰ-Rhodamine B in ihe presence of polyvinyl alcohol. The maximum absorption of the ion-association complex was at 595nm, Beer's law was obeyed for mercury (Ⅱ ) in the range of 0~5?g/25ml. The apparent molar absorptivity was 7. 36 ?105L/mol?cm. The recovery of mercury was 97. 0% ~ 103. 0%,RSD

Purpose To explore the clinical value of131I-whole body scan (131I-WBS) and 18F-FDG PET/CT on the metastatic management of patients with differentiated thyroid cancer (DTC) after operation.Materials and Methods Serum thyroglobulin (Tg) of 27 patients after DTC surgery was measured one day before131I therapy, and the patients underwent131I-WBS on 3-5 days after131I therapy. According to the results of Tg and 131I-WBS, all the patients were divided into 4 types as follows: type I: Tg (+),131I-WBS (-); type II: Tg (+),131I-WBS (+); type III: Tg (-),131I-WBS (+); and type IV: Tg (-), 131I-WBS (-). Then the patients received18F-FDG PET/CT scan within a week after 131I-WBS. The results of131I-WBS and18F-FDG PET/CT scan were analyzed according to histopathologic findings or clinical and imaging follow-up of at least 6 months as diagnosis standard.Results The examinations uncovered that metastasis occurred in 52 lesions of 22 cases out of the 27 cases.131I-WBS revealed 24 metastatic lesions (46.2%) in 8 cases (36.4%), and18F-FDG PET/CT showed 35 metastatic lesions (67.3%) in 15 cases (68.2%), the difference with statistic significance (χ2=4.46 and 4.74,P<0.05). Metastasis were confirmed in 13 type I cases (100.0%); 5 type II cases (100.0%); 3 type III cases (100.0%) and 1 type IV case (16.7%), respectively. The rate of detecting metastasis by 18F-FDG PET/CT was 100.0% in type I, 20.0% in type II, 0% in type III respectively, the difference with statistic significance (χ2=9.14 and 10.11,P<0.05); and 100.0% in type IV, the difference without statistic significance (χ2=1.25,P>0.05). Based on that, therapeutic plans were modified for 13 patients with type I metastasis and 1 patient with type IV metastasis.Conclusion131I-WBS and18F-FDG PET/CT are complementary for detecting metastatic lesion and help to decide the following treatment of DTC patients after surgery. Moreover,18F-FDG PET/CT shows advantages in detecting metastatic lesion in Tg-positive and negative131I-WBS type of DTC patients after surgery, thus can provide an important clinical guidance for this type of patients.

Objective To analyze the image characteristics of chest schwannoma in coincidence 18FFDG SPECT studies,and to evaluate its prospective diagnostic function on chest schwannoma.Methods Four cases confirmed as schwannoma by surgery and pathology were enrolled in this retrospective study.Enhanced CT and coincidence 18F-FDG SPECT studies were performed before surgery.Imaging characteristics for the diagnosis of chest schwannoma were summarized.Results Tumors were totally removed by surgery.The histological diagnosis of schwannoma was confirmed by pathological,HE and immunohistological staining examination (positivity for the S-100 protein and vimentin),including 1 case of malignant schwannoma and 3 cases of benign.Four cases all showed high uptake of 18F-FDG.The uptake in malignant schwannoma was much higher than that in benign schwannoma.Benign schwannomas were noninvasive masses and mainly showed compression symptoms,with obvious lobulation and distinct borders.Malignant schwannoma was invasive masses.Conclusions 18 F-FDG coincidence SPECT is of limited value as a prospective diagnostic imaging technique for the identification of benign schwannoma from malignant schwannoma.But it could play an important role in the staging,restaging,and post-therapy follow-up of schwannoma.

Objective To analyze the latency of posture evoked response of normal lower limb muscle in different stimulations and explore its influencing factors. Methods The normal lower limb was induced to produce postural evoked response by the dynamic posturography through two kinds of perturbations, the supporting surface rotation stimulation (Toes-up and Toes-down) and the horizontal perturbation stimulation (Forward and Backward). The latencies of tibialis anterior muscle and gastrocnemius muscle were recorded by surface electromyography acquisition system. The differences of the left and right limb, gen-der and height on the latency of postural evoked response were analyzed. Results (1) Under the Toes-up and Backward perturbation, the latency of tibialis anterior muscle was longer than gastrocnemius muscle;under the Toes-down and Forward perturbation, the latency of gastrocnemius muscle was longer than tib-ialis anterior muscle. (2) The latencies of left limb and right limb had no significant difference. (3) The la-tency in male was longer than that in female. (4) The latency gradually increased with the increase of height. Conclusion In the postural evoked response, different perturbations, gender and height have sig-nificant impacts on the latency of posture evoked response of lower limb muscle. However, the effect of height and gender should be not considered referring to the same individual.
