Objective To study the application of ultrasonic freestyle extended imaging(FEI) in thyroid,breast,artery,vein diseases.Methods Thirty-five patients with above mentioned diseases were examined by FEI and the images were analyzed.Results FEI could entirely show the scan region needed.It also could enhance image quality,show the physiologic radian of the body,measure the nidi accurately.Conclusion The FEI technology provides more image information and is of great help to improve the clinic diagnosis ratios.

Objective To explore the clinical application value of transcranial Doppler on patients with hyperlipidemia. Methods 80 patients with hyperlipemia and 70 healthy people were studied by transcranial Doppler ultrasound(TCD) of interal carotid artery hemodynamics. Results 57 (71.7%)of the 80 patients with hyperlipemia had arteriosclerosis, and terminal sclerosis happened on 12 patients ( 13.3% ). Compared with the control group, the difference was all statistically significant ( P ＜ 0.05 ). Conclusion Hemodynamics at the terminal of interal carotid artery patients with hyperlipemia was obvious abnormal studied by transcranial Doppler ultrasound (TCD) , and sclerosis of interal carotid artery is common complication of patients with hyperlipemia. Results showed that TCD could be used as a routine method for testing of patients with hyperlipemia and had some value in preventing cerebrovascular disease induced by hyperlipidemia.

Sometimes a pilomatrixoma on upper neck can be misdiagnosed as primary salivary gland tumor, skin adnexal tumor or metastatic carcinoma. On fine needle aspiration cytology(FNAC), characteristic features are ghost cells, basaloid cells, and calcium deposits, among which presence of ghost cells seems to be the key to recognize it. Here we present a cytologically misdiagnosed case of pilomatrixoma. A 32-year-old man presented a subcutaneous mass on the right posterior neck. It has grown slowly for 1 year, and was nontender, well circumscribed, hard, and movable mass. An initial FNAC yielded only monomorphic population of highly mitotic basaloid cells, without anucleated ghost cells, chronic inflammatory cells or foreign-body giant cells, suggestive of a poorly differentiated carcinoma. However, that was inconsistent with patient's clinical findings. For further correct diagnosis, FNAC was repeated, which yielded the basaloid cells and foreign-body giant cells. The diagnosis of pilomatrixoma could be made and the mass was excised. This case demonstrates that the pilomatrixoma should be considered in the differential diagnosis of subcutaneous aspirates containing not ghost cells but a dominant population of basaloid cells.

BACKGROUND:Apolipoprotein E is one of the important plasma apolipoproteins with polymorphism and involved in lipid metabolism and cholesterol balance modulation, playing also a role in the normal growth and repair of the nervous system.OBJECTIVE: To analyze apolipoprotein E gene polymorphism in patients with vascular dementia (VaD) in comparison with patients with cerebral infarction (CI) patients and healthy controls, so as to elicit the relationship between apolipoprotein E gene polymorphism and VaD.DESIGN: Case-control study.SETTING: Department of Neurology, General Hospital of Jinan Military Area Command of Chinese PLA.PARTICIPANTS: The participants were recruited from the inpatients and outpatients with cerebrovascular diseases and healthy subjects for routine physical examination in the General Hospital of Jinan Military Area Command of Chinese PLA between August 2001 and October 2003, including 35 cases of VaD, 36 CI cases and 40 healthy controls.METHODS: Four milliliters of venous blood was collected from the elbow vein form all participants after fasting for 12 hours for detection of apolipoprotein E genotype using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Blood lipids and apolipoprotein contents were also examined.of triglyceride, total cholesterol, high-density lipoprotein cholesterol (HDLC), low-density lipoprotein cholesterol (LDL-C), as well as apolipoprotein A and aoplipoprotein B.RESULTS: Data of 35 VaD 36 CI patients and 40 healthy controls were all VaD group and CI group had higher ε4 allele frequency were higher (22.86% and 22.22% vs 7.5%, respectively, P ＜ 0.05) but lower ε3 allele frequency (70% and 69.45% vs 86.25%, respectively, P ＜ 0.05); the frequencies of all alleles were basically comparable between VaD and CI groups er in E ε4 allele carriers [(5.85±L03), (4.73±0.29), (4.96±0.87) mmol/L, respectively] than in E ε2 [(3.91±0.87), (3.12±0.65), (3.06±0.33) mmol/L] and ε3 [(1.34±0.21), (1.00±0.28), (0.94±0.32) g/L] allele carriers in VaD group (P ＜ 0.05).CONCLUSION: Apolipoprotein E gene polymorphism is closely associated with the onset of VaD, for which ε4 allele might be a risk factor with similar impact in CI.

In this paper five nutritive indexes of Ulva pertusa were measured in Liaoning coast. The results showed that in dry powder of Ulva pertusa, the protein was 6. 03% , crude fat was 3. 12%, carbohydrate 38. 88%, moisture content 12. 27%, ash content 39. 7, etc. In which the carbohydrate is made up of rhamnose, glucose, xylose, triose, fucose, mannose, galactose, arabinoe etc, measured with gas chromatography. There were many inorganic elements, such as calcium, magnesium, zinc, selenium. The results indicate that Ulva pertusa is rich in nutritive components and can be developed into valuable function food.
