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.

People departure from the treatment, prevention and health care purposes, intermittently or continuously excessive use of drugs with dependence, will cause serious mental and physical damage, while serious social harm.Opioids are the most commonly abused drug, abusers by taking an excess number of pills orally or by crushing the pills, followed by smoking, snorting, or injecting the new altered formulation to get euphoric.The escalating abuse of opioids has recently spawned the development of novel drug formulations resistant to various methods of tampering and misuse.This article discusses available opioids that include abuse-deterrent mechanisms as well as such agents currently in development.

Objective To investigate the impact of early enteral nutrition on the prognosis of severe head injury patients.Methods According to the different nutritional therapy,160 cases of severe craniocerebral injury patients were randomly divided into two groups using random digit.Two groups of patients were all given similarly conventional methods,the observation group were given early enteral nutrition therapy,the control group were given routine nutrition.CD3+,CD4+,IgE,IgG immune factors were observed after treatment for 10d.Results 10d later,the serum IgG,IgM,IgA in the observation group were significantly higher than those in the conventional nutrition group(t =2.18,3.42,11.23,all P ＜ 0.05),IgE was significantly lower than that in the conventional nutrition group (t =4.76,P ＜ 0.05) ;The serum T-lymphocyte subsets CD3+,CD4+ level in the observation group were higher than those in the conventional nutrition group(t =21.41,5.38,all P ＜ 0.05),the incidence of complications of the observation group was 23.75%,which was significantly lower than 55.00% in the conventional nutrition group(x2 =4.73,P ＜ 0.05).Conclusion Early enteral nutrition therapy can significantly improve the immunity of severe head injury patients,reduce complications,thereby improve the prognosis and the patient's quality of life.

Objective To investigate the effect of pelvic floor muscle exercise on perimenopausal female sexual dysfunction. Methods Forty six patients with perimenopausal female sexual dysfunction received pelvic floor muscle exercise. Sexual function and pelvic floor muscle strength were compared between pre-and post-exercises. Result The patients′pelvic floor muscle strength and sexual function after exercises were significantly better than those before the exercises (P<0.05). Conclusion Implementation of the pelvic floor muscles exercise in the patients with perimenopausal sexual dysfunction can strengthen pelvic floor muscle and thus alleviate their sexual dysfunction.

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 observe the effect of rosuvastatin on serum hs-CRP,IL-18 levels in patients with acute myocardial infarction.Methods By randomized,double-blind,controlled study,102 patients with acute myocardial infarction were randomly divided into the treatment group(rosuvastatin 10mg/d,continuous medication 14d) and the control group(not used rosuvastatin,other treatment and care were same with the treatment group).Before treatment,24h after treatment,after 2 months of follow-up,the serum hs-CRP and IL-18 levels were detected and compared.Results After treatment,the serum hsCRP level increased and then decreased,24h after treatment,the serum hsCRP level of the treatment group increased to (15.54 ±2.51) mg/L,which was significantly lower than the control group (19.26 ±.2.92) mg/L (t =4.65,all P ＜ 0.05).2 months after treatment,the serum hs-CRP levels of the two groups were decreased to (3.21 ± 1.39) mg/L and (7.67 ± 2.07) mg/L,the difference was statistically significant (t =5.54,4.63,all P ＜ 0.05).After treatment,the serum IL-18 level decreased,24h after treatment,the serum IL-18 level ofthe treatment group decreased to (29.13 ±6.34)pg/L,which was significandy lower than the control group (33.01 ± 7.34) pg/L(t =3.59,P ＜ 0.05).2 months after treatment,serum IL-18 levels of the two groups were decreased to (27.52 ± 5.33) pg/L and (32.01 ± 6.24) pg/L,the difference was statistically significant (t =3.87,3.28,P ＜0.05).Conclusion Rosuvastatin can significantly reduce the serum hsCRP and IL-18 levels in patients with acute coronary syndrome,it has better anti-inflammatory effect and can be used as a new therapeutic target for acute myocardial infarction.

Objective To explore the clinical efficacy and toxicity of idarubicin (IDA)-based IA regimen as induction chemotherapy in treating acute myeloid leukemia (AML) within different risk groups.Methods Data collected in 60 patients initially diagnosed and treated with one course of IA regimen were studied retrospectively.Results Efficacy were different for patients treatment with different prognosis after one course of IA chemotherapy,CR rates achieved in patients with favorable,intermediate and unfavorable prognosis were 83.3 ％ (10/12),73.1％ (19/26),59.1％ (13/22) respectively,PR rates were 16.7 ％ (2/12),19.2％ (5/26),13.6％ (3/22) while ORrateswere 100％ (12/12),92.3 ％ (24/26),72.7 ％ (15/22)respectively.After 2 years of follow-up,relapse free survival (RFS) rates were 100 ％ for patients with good prognosis,53.8 ％ for those with moderate prognosis,and 45.5 ％ for people with poor prognosis.The outcome showed that there were significant differences among these three group (P =0.042).Myelosuppression and infections due to neutropenia were the main adverse effects,and severe non-hematologic toxicities were not observed.Conclusion IA regimen as induction chemotherapy may be an efficacious and safe solution and achieve a higher CR rate and 2 years RFS rate for patients diagnosed as AML with good prognosis.Hematopoietic stem cell transplantation should be considered as soon as possible for patients with moderate or poor prognosis.
