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.

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 To evaluate the clinical effects of platelet-rich plasma in treatment of DeepⅡburn wounds. Methods Sixty eight cases of inpatients with Deep Ⅱburns were selected, whose age were from 1 to 65 years and their burn areas were between 5%~62%of total body surface area (TBSA). Deep gradeⅡburn of each sample was divided into two parts. Part A was the treatment group and part B was the control group.The burn wounds in the treatment group were treated with platelet-rich plasma and the counterpart in the control group were treated with SD-Ag. Healing time ,recovering rate and the frequency of dressing changes,frequency of changing the most innerlayer gauze and the rate of wound infection were also analyzed. Finally the laboratory abnormalities and adverse effect were monitored regularly. Results The healing time of the treatment group (16.5±3.1 ) d was shorter than that of the control group (19.5±3.8 ) d. The recovering rate of the treatment group was higher than that of the control group on the 14th and 17th day after treatment. There were statistically sig?nificant differences between these two groups (P<0.05). After two weeks’treatment, the internal and external dressing per?meability into wet gauze layers were 20.6 ± 1.7, which were significantly decreased than that in the control group 23.3 ± 5.9. The frequency of dressing changes was(7.2±1.1)times in treatment group versus(9.2±1.4)times in control group and the frequency of changing the inner most layer gauze was( 2.3±0.6)times in the treatment group versus(5.3±1.3)times in con?trol group. There were 5 inflammation reaction cases in the treatment group, but 13 cases in the control group. However, there was no statistic significance between the two group in the outcomes of bacterial culture, the laboratory abnormalities and the adverse effect. Conclusion Platelet-rich plasma can remarkably shorten the healing time,improve healing rate,re?duce frequency of dressing change and promote wound healing for deepⅡburn wound. PRP is a potential safety reagent in treating deepⅡburn wound.

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.
