Surface-enhanced laser desorption ionization spectrometry (SELDI),as a new type of proteinchip technique,could easily and quickly acquire the information of proteins in all kinds of body fluid and tissue. It could be used in selecting new tumor markers,early diagnosis and evaluating the risk of tumors. This article introduces the principium of this ProteinChip technique,its application in clinic detection,and the outline of its future.

Objective:To evaluate the feasibility of the 3-D surface reconstruction by multislice spiral CT(MSCT) technique in the diagnosis of impacted teeth in maxilla.Methods:Eighty two cases with impacted teeth in maxilla were examined with volumetric CT scan using MSCT,the dental reconstruction images were obtained with multiplanar reformation technique and 3D-reconstruction technique.Results:Dental surface 3D-reconstruction image could display the shape,location and eruption orientation of the impacted teeth clearly.Conclusion:3-D surface reconstruction by MSCT can provide valuable diagnostic and anatomic information of the impacted teeth in maxilla.

Objective To detect the antimutagenesis of carrot juice and to provide necessary data for the development of fruit-vegetable beverage. Methods Revised rat salmonella mutagenicity test was used, strains had been cultured for 48 hours at a constant temperature of 37 ℃. We counted the anaphysis strains produced in the paper circle, and judged whether there was a antimutagenesis effect according to the difference of the anaphysis strain number between the samples and the dissolvent controls. We also judged the mutagensis effect of the samples based on the anaphysis strains outside the paper circle. Results TA98-TA100 strains were all inside the normal scope, mutagenesis effect of all samples had not been observed. Conclusion Under our laboratory conditions, the inhibition rate of sample Ⅰ,Ⅳ on the induction of N-methy1-N/-nitroso-N-nitrosoguanidine(MNNG) to TA100-S9 and of sample Ⅱ, Ⅲ on the induction of aflatoxin B1( AFB1) to TA+S9 was high, and dose-response effect was obvious, also the inhibition effect of both sample Ⅰ,Ⅱ on the induction of AFB1 and that of sample Ⅰ on the Benzo(a)pyrene (BAP) to TA100+S9 was relatively high, but there was no dose-response effect exist.

There is a small amount of liquid in healthy people's abdomen,but excessive liquid in abdomen has been called peritoneal effusion or ascites.Ascites is a common clinical sign.Though many causes can lead to ascites,cirrhosis,malignancy and tuberculosis are more common.According to different causes and physical and chemical properties,ascites can be divided into extravasate and transudate.It is important to distinguish between benign and malignant ascites,but sometimes the differential diagnosis is difficult.In this paper,the characteristics of the ascites,the procedure of diagnosis and treatment are discussed.

Objective To evaluate retrospectively ECG -gating for the coronary angiography with MSCT. Methods 15 patients were studied with a multislice spiral CT on retrospective ECG -gating,0.5s rotation, and cardial segment reconstruction algorithm. Nine phases were chosen to reconstruct images of coronary arteries. Results In the 230 coronary artery segments,213 (91%)were best visualized at 70%. And 15 (6.4%), 9 (3.8%), and 3 (1.3%) were optimal at 80%, 40% , and 5% of the cycle respectively. Conclusion The coronary arteries usually are best visualized at 70% image reconstruction window of the cardial cycle.

0.05). Oil red O staining demonstrated that lipid droplet number was significantly less in the each adipogenic inductor + extracting solution from Eucommia ulmoides Oliv. groups compared with the adipogenic inductor group. CONCLUSION: Extracting solution from Eucommia ulmoides Oliv. can induce the differentiation of in vitro cultured goat BMSCs into osteoblasts, and inhibit their differentiation into adipocytes.

Objective To explore the change of peripheral benzodiazepine receptors (PBR) expression in the telencephalon of mice with schistosomiasis. Methods The changes of PBR mRNA in the telencephalon of schistosomiasis mice were observed by the real-time FQ-PCR method. The results were judged with circle number of times (C_T) when the level of amplification exponent achieved detecting liminal value. Results Comparing the experiment group (n=10) with the healthy control (n=10) at the 8th、12th、20th week, the changes of C_T were significant(P

Four diterpenoid alkaloids were isolated from Aeonitum longtounens T. L. Ming grown in Lijiang of Yunnan Province, for the first time. They were identified as foresaconitine, chasmaconitine, delsoline and delcosine by Physical contants and spectral data.

One hundred and thirty-two cases of acute facial paralysis involving the channels and collater als (Group A) were treated with acupoint injection of dexamethasone combined with radiance of TOP. And ninety-three cases treated with acupuncture served as the control (Group B). The results showed that the therapeutic effect in Group A was superior to that in Group B ( P

Pathological changes of uterine fibroide after transcatheter uterine artery embolization(TUAE) has been proven with regular pathological change during the elapse time after TUAE resulting in fibrotic proliferation. Inflammation took place first, followed by coagulation necrosis and hyaline degeneration but incomplete in most cases and finally with proliferative fibrous tissue formation. These dynamic changes of pathology are basis for fibroid volume reduction and recurrences. The factors affecting the extent of fibroid necrosis included tumor size,position and elapse of duration after TUAE. Inflammation was found in normal uterine tissue after TUAE but no necrosis occurred. The finding of embolization agent in peripheral vessels of adnexa may suggest future possible damage of function in ovary and fallopian tube. (J Intervent Radiol, 2006, 15: 507-509)
