1.Application of adaptive enhancement means in head and neck CR images
Chinese Journal of Medical Imaging Technology 2009;25(12):2294-2296
Digital CR of head and neck overcomes the disadvantage of regular X-ray radiography, which can not reveal bone and soft tissue position deficiency in one exposing, and reduces the X-ray radiation dose. Meanwhile, various factors decline the imaging quality, and images must be enhanced in order to meet demands of doctors clinical diagnosis. The general enhancement algorithms don't consider bodys structure difference and density characteristics. A new adaptive CR enhancement algorithms was proposed in this article, and head and neck images were processed with this method and compared with linear unsharp masking method. The results proved that the details of CR image enhanced were abundant and enhanced CR had good visual effect. SNR was high, as well as detail variance/background variance (DV/BV) indicating that this algorithms is suitable for head and neck CR medical image.

Objective To investigate the Effect of Tetramethylpyrazine on adhesion and invasion ability of Cell PG in Hypoxic Environment. Methods The revival cell PG was divided into three dosages(high, medium and low)group of Tetramethylpyrazine, DDP group and negative control group. All of five groups were cultured separately in the normal and hypoxic environment. The adhesion ability of Cell PG were detected by MTT. The invasion ability of Cell PG were detected by Transwell chamber. Results Observed on the reconstruction of the basement membrane adhesion in PG cells by MTT, in normoxic environment the mean absorbance of the TMP high, medium and low concentrations, cisplatin group, control group were (0.556±0.040),(0.519±0.056), (0.517±0.061),(0.333±0.057),(0.300±0.066), P<0.01. In hypoxic environment the mean absorbance of the TMP high , medium and low concentrations, cisplatin group, control group were (0.48±0.032),(0.452±0.059),(0.274±0.093),(0.464±0.099),(0.155±0.042), P<0.01. Promotion of cell adhesion with Tetramethylpyrazine of high, medium and low concentration group and DDP group in hypoxic environment is greater than in normoxic environment(P<0.01). Observed the reconstruction of the invasion of basement membrane of PG cells by Transwell chamber, in normoxic environment the invasive cells of the TMP high, medium and low concentrations, cisplatin group, control group were :(28.00±17.00),(91.67±30.37),(105.67±39.58),(85.00±8.19),(152.33±24.71), P<0.05. In hypoxic environment the invasive cells of the TMP high , medium and low concentrations , cisplatin group, control group were (20.33±15.31), (22.33±17.62),(56.00±11.53),(57.67±35.95), (76.33±18.01), P<0.05. The invasive cells of normoxic control group was significantly more than hypoxic control group(P<0.05). Conclusion In hypoxic environment , adhesion and invasion ability of Cell PG significantly decreased compared with normoxic environment ; In normoxia and hypoxia environment, Tetramethylpyrazine and cisplatin could promote the adhesion ability and inhibit the invasion ability of PG cells. Role in promoting of Tetramethylpyrazine on cell adhesion of PG cells was stronger in hypoxic environment.

OBJECTIVETo evaluate the short effect and safety of the acupoint application of dog days for allergic rhinitis.
METHODSTwo hundred and forty-nine patients were randomly divided into an application group (166 cases) and a placebo group (83 cases). On the first day of the first dog days, the first day of the second of the three ten-day periods of the hot season and the first day of the last of the three ten-day periods of the hot season, acupoint application was adopted mainly at Dazhui (GV 14), Feishu (BL 13), Pishu (BL 20) and Shenshu (BL 23) in the application group. The plaster was made of Chinese herbs, including Baijiezi (semen brassicae), Xixin (asarum), Yanhusuo (corydalis tuber) and Gansui (euphorbia kansui). Buckwheat plaster without medical ingredient was used in the placebo group. The application was pasted for 2-6 h every time. On the first three days of all the three periods of dog days, treatment was used continuously. The whole period of dog days was made into one course. The changes of symptom and syndrome scores, visual analogue scale (VAS) for symptom before and after treatment and the adverse reaction with the condition disposed were observed in the two groups.
RESULTSAfter treatment, the symptom and syndrome scores and VAS for symptom were improved compared with those before treatment in the two groups (all P < 0.05), and the improvements of the application group were more obvious than those of the placebo group (all P < 0.05). The short effective rate of the application group was 68.1% (113/166), which was better than 48.2% (40/83) of the placebo group (P < 0.05). The adverse reaction rates were 4.2% (7/166), 2.4% (2/83) respectively, with no statistical significance between the two groups (P > 0.05).
CONCLUSIONThe dog days plaster achieves obvious effect with good safety for allergic rhinitis.

Objective To study the effect of p50 on IKKα at IL-1β promoter in LPS tolerant cells and to reveal the mechanism of the inhibition of IL-1β mRNA by pS0. Methods THP-1 human promono-cyte model of endotoxin tolerance that simulates the sepsis leukocyte phenotype was used. Chromatin immu-noprecipitation assay(CHIP) and real-time PCR were applied to quantify the binding of p50 and IKKα to IL-1βpromoter. IL-1β mRNA transcription was studied after knocking-down of p50 and/or IKKα. Results With LPS stimulation, p50 binding did not reduce but somewhat increased at IL-1β promoter in tolerant THP-1 cells. Knocking-down of p50 increased the transcription of IL-1β mRNA, which revealed the inhibi-tory effect of p50 in tolerant cells. In contrast, the accumulation of IKKα to IL-1β promoter decreased with LPS stimulation in tolerant cells; However, IKKα binding increased after p50 gene knock-down. In the meantime, IL-1β mRNA transcription increased; At last, IL-1β mRNA decreased again after double-knoc-king down of p50 and IKKα. Conclusion p50 is an inhibitory protein at IL-1β promoter in tolerant THP-1 cells. The unresponsiveness of IL-1β mRNA transcription to LPS at least partly results from the inhibition of IKKα binding to IL-1β promoter by p50.
