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 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 investigate the effect of Glutamine (Gln) on heat stress-induced dysfunction of intestinal epithelial barrier. Methods Human intestinal epithelial Caco-2 cells were pre-incubated with Gln for 24h and then exposed to heat 43℃ for 1h. Cell counting kit-8 (CCK-8) was used to detect the cellular proliferation with various concentrations of Gln and choose an optimum concentration for subsequent experiments. The barrier integrity was measured by transepithelial electrical resistance (TEER) and horseradish peroxidase (HRP) permeability. Levels of tight junction protein occludin and ZO-1 were analyzed by Western blotting. Cytoskeleton using Coomassie blue staining was observed by microscopy. Results At 0.7mmol/L concentration, Gln showed the most effective cell proliferation compared with other concentration groups (P<0.05). Therefore, 0.7mmol/L Gln was used as effective concentration in following experiments. Gln attenuated the TEER decrease and impairment of intestinal permeability induced by heat exposure compared with 43℃ group (P<0.01). The expressions of occludin and ZO-1 were significantly elevated by pretreatment with Gln. The distortion of cytoskeleton was also effectively prevented. Conclusion 0.7mmol/L Gln is potentially beneficial for protecting against heat stress-induced permeability dysfunction and epithelial barrier damage.

Objective To investigate the risk factors of mental disorders of patients treated in intensive care unit(ICU).Methods Collected from January 2013 to December 2014 ICU stay eligible cases,and analyzed the past history (hypertension,intemperance),previous surgery,mechanical ventilation,date of ICU admission,quality of care, APACHE II score,electrolyte disorder,LVEF,sleep disturbance,PCT,oxygenation index,drug use situation (midazo-lam,opioids)and the clinical care unit the incidence of mental disorders in relationship.Results 568 patients (male 345 cases,female 223 cases),mental disorders group of 157 patients,the clinical incidence rate of 27.6% overall;568 patients were in the sex ratio of 1.55:1,mental disorders group of 157 patients(96 males,61 females),male to female ratio 1.57:1,mean age was (65.5 ±11.2)years;no mental disorders group (249 males,162 females),male to female ratio 1.30:1,mean age was (48.8 ±14.3)years.Logistic regression analysis revealed that coronary heart disease,hypotension,alcohol abuse,surgery,mechanical ventilation,ICU admission time,quality of care,APACHE II score,electrolyte imbalance,ejection fraction,sleep disorders,procalcitonin,oxygenation index,use of midazolam or opioids were among the risk factors of ICU mental disorders.Mechanical ventilation,quality of care,hypotension,alco-hol abuse,and use of midazolam were independent risk factors for ICU mental disorders (all P <0.05).Conclusion ICU inpatients with past history of hypertension and intemperance,use of mechanical ventilation and midazolam should be closely monitored and evaluated,early psycho -psychiatric screening,and take effective measures in time;high -quality care can reduce the incidence of mental disorders in ICU patients significantly.
