Dual material gate SOI MOSFET with asymmetrical halo can suppress short channel effect and increase carriers transport efficiency. The analytical model of its subthreshold drain current is derived based on the explicit solution of two-dimensional Poisson's equation in the depletion region. The model takes into consideration the channel length modulation effect and the contribution of the back channel current component. Its validation is verified by comparision with two dimensional device simulator MEDICI.

Objective It has been shown that ketamine attenuates cytokine production and release induced by endotoxin. The purpose of this study was to investigate the effects of diazepam and ketamine on inflammatory responses during early stage of burn. Methods BALB/C male mice weighing 20-25 g were randomly divided into 5 groups : (1) normal control group (n = 10); (2) burn control group received Ⅲ degree bums covering 15%-20% of the body surface (n = 10); (3) D-K group received intramuscular diazepam 0.4mg?kg-1 and ketamine 10 mg?kg-1 ( n = 10); (4) D + K pretreatment group received D + K 15 min before burn ( n = 10) and (5) D + K post-treatment group received D + K 15 min after burn ( n = 10) . Four hours after burn or anesthesia (D + K) the animals were sacrificed and blood was collected for determination of serum TNF-?, IL-1? and IL-10 concentrations (ELISA) and peritoneal macrophages were isolated for detection of glucocorticoid receptor (GR) by Western blotting. In addition peritoneal macrophages isolated from normal animals (group 1) and bum animals (group 2) were cultured with diazepam-ketamine for 1 h befor detection of GR.Results Serum TNF-?, IL-1? and IL-10 levels in group 2 were significantly higher than those in group 1. In group 4 and 5 serum TNF-?, IL-l? and IL-10 levels were significantly lower than those in group 2. In group 4 only serum IL-10 level whereas both serum IL-1? and IL-10 levels in group 5 were significantly higher than those in group 1. GR of peritoneal macrophage was significantly down regulated 4 h after bum (group 2) as compared with group 1. The level of GR in group 4 was significantly higher than that in group 2 but not significantly different from that in group 1; whereas the GR level in group 5 was significantly higher than that in group 2 but lower than that in group 1 and 4. There was no significant difference in GR expression after macrophages were cultured in vitro with diazepam and ketamine between normal or bum groups. Conclusion Diazepam-ketamine pretreatment can suppress cytokine release induced by severe bum. The expression of GR in peritoneal macrophages is significantly reduced by bum. Diazepam-ketamine given before or after bum can suppress the inflammatory response but have no direct effect on peritoneal macrophages.

Objective To investigate the value of DNA-image cyt-ometry (DNA-ICM) in the diagnosis of urothelial cell carcinomas (UCC). Methods Totally 162 voided urine specimens (92 cases from urothel-ial car-cinomas patients and 70 cases from benign urinary system diseases patients ) were detected with DNA-ICM and liquid-based cytology (LBC), respectively. Results The sensitivity and specificity of DNA-ICM were 65.2%and 100% respectively in the diagnosis of UCC but those of LBC were 27.2% and 98.6%, respectively. The sensitivity of DNA-ICM was significantly higher than that of LBC in the diagnosis of UCC (P < 0.01). The sen-sitivity of DNA-ICM in upper urinary tract urothelial cell carcinomas (UTUC) were 77.1%, which was much higher than that in bladder urothelial cell carcinomas (57.9%) but no statistical significance was found (P >0.01). Conclusion DNA-ICM, which improves the positive rate of urinary cytology, has great application value in the diagnosis of urothelial cell carcinomas and it is an effective screening method for urothelial cancer in diag-nosis and follow-up.

This study was aimed to investigate the distribution of tumor necrosis factor-alpha (TNF-alpha)-308 gene polymorphism and its correlation with asthma in TCM syndromes between Han and Uyghur People in Xin-jiang. The polymerase chain reaction - restriction fragment length polymorphism (PCR-RFLP) method was applied in the detection of TNF-alpha-308 gene polymorphism among 160 bronchial asthma cases and 40 healthy con-trols. Traditional Chinese medicine (TCM) syndrome differentiation standard on bronchial asthma was applied in the syndrome differentiation of 160 bronchial asthma cases. And gene distributions of TCM syndrome differentia-tion were compared. The results showed that there was no significant difference between the genotypes (wild-type and mutant) and allele distribution between the asthma group and the normal control group, the Uyghur asthma group and Uyghur normal control group, the Han asthma group and Han normal control group, Uyghur normal control group and Han normal control group (P > 0.05). There was no significant difference on the TNF-alpha-308 genotype distribution among different TCM syndromes. There was no significant difference on TCM syndrome distribution between Han asthma patients and Uyghur asthma patients. It was concluded that bronchial asthma in Xinjiang may be nothing to do with ethnic group, TNF-alpha-308 gene polymorphism. And the bronchial asthma syndrome differentiation type may be nothing to do with the TNF-alpha-308 genotype distribution.
