ObjectiveTo investigate the influence of the midazolam sedation based on remifentanil analgesia on the occurrence of delirium in critically ill patients in intensive care unit (ICU).Methods A single-center prospective randomized controlled trial was conducted. 140 consecutive critically ill patients admitted to ICU of Peking University People's Hospital, undergoing mechanical ventilation longer than 24 hours, with the need of sedation, from February 2014 to January 2015 were enrolled. They were randomly divided into two groups by computer generated random numbers table, eachn = 70. The patients in observation group received midazolam 1μg·kg-1·min-1 for sedation, and 1 mg/mL remifentanil for analgesia with 0.05 mg/kg intravenous bolus, then continuous infusion of 0.02-0.10 mg·kg-1·h-1. The patients in control group received midazolam for sedation only. The data were recorded as follows: the main indices for observation included the occurrence of delirium and its duration; the second item for observation was consumption of drug for sedation, followed by the mean arterial pressure (MAP) before and after sedation, the time of wake-up, duration of mechanical ventilation, the length of ICU stay, and 28-day fatality rate. The 28-day survival was analyzed by Kaplan-Meier survival curve.Results The dosage of remifentanil used in observation group was (98.6±24.9) mg/d, the dosage of midazolam was significantly lower than that of the control group (mg/d: 160.6±33.3 vs. 178.9±43.4, t = 2.829,P = 0.005), the incidence of delirium was obviously lower than that of the control group [22.9% (16/70) vs. 57.1% (40/70),χ2 = 15.700,P< 0.001], and the time of delirium was slightly shorter than that of the control group (hours: 162.9±78.0 vs. 194.8±117.3,t = 0.947,P = 0.348). Among the patients with delirium, the dosage of dexmedetomidine used in observation group was significantly less than that of the control group (mg/d: 0.54±0.11 vs. 0.64±0.14,t = 2.112,P = 0.041). The MAP before sedation was similar as the MAP after sedation in both groups, and there was no significant difference between observation group and control group [mmHg (1 mmHg = 0.133 kPa), before treatment: 84.7±16.2 vs. 89.5±37.7, after treatment: 82.3±10.7 vs. 80.8±13.9, bothP> 0.05]. There was no significant difference in the time of waking-up between observation group and control group (hours: 2.3±0.9 vs. 2.4±0.8,t = 0.487,P = 0.627). The duration of mechanical ventilation (hours: 143.4±138.3 vs. 163.9±158.9, t = 0.812,P = 0.418), the length of ICU stay (days: 8.8±7.7 vs. 10.0±7.8,t = 0.917,P = 0.361) and 28-day fatality rate [11.4% (8/70) vs. 20.0% (14/70),χ2 = 1.941,P = 0.245] in observation group were slightly lower than those of the control group without significant difference. Kaplan-Meier survival curve showed that the cumulative 28-day survival rate in observation group was slightly higher than that of control group (χ2 = 1.647,P = 0.199). ConclusionAnalgesia based on sedation may reduce the occurrence of delirium and its severity, furthermore, even if delirium occurs, it may be less severe.

Objective To explore the effects of clinical psychological intervention on anxiety and depression in hemodialysis patients .Methods Hemodialysis patients were randomly divided into two groups:psychological inter-vention group and control group ,25 patients in each group .In intervention group ,besides routine clinical treatment and nursing measures ,we analyzed the clinical information of the patients ,consulted the relevant documents ,combined the evidence and clinical experience ,and finally conducted the psychological intervention .Self-Rating Anxiety Scale and Self-Rating Depression Scale of these patients were analyzed .Results Before the intervention , the SAS and SDS scores of intervention group and control group were (57.3 ±1.5) versus (56.9 ±1.6) and (55.3 ±2.3) versus (56.1 ±3.5),respectively.The t values were 0.912(P>0.05) and 0.955(P>0.05),respectively.After interven-tion,the score before and after the trial between these two groups were significantly different (P<0.05).The SAS and SDS scores of intervention group and control group were (16.4 ±0.9) versus (10.1 ±1.3) and (14.3 ±2.1) ver-sus (9.7 ±1.5),respectively.Conclusion Clinical psychological intervention can effectively relieve anxiety and depression in hemodialysis patients .

A total of 218 patients on chemotherapeutic regimens containing oxaliplatin were randomly divided into experimental (n =120) and control (n =98) groups.The experimental group received an intravenous infusion of lipoic acid plus sodium potassium magnesium calcium and glucose injection.The control group had only normal saline.Overall incidence of neurotoxicity and toxicity grade of peripheral nerve were observed after 4,8 and 12 cycles.Those with neurotoxic symptoms were followed up for 1 year.No significantly statistical difference existed in the incidence of peripheral neurotoxicity after 4,8 cycles (P ＞0.05).After 12 cycles,31 patients in the experimental group had an onset of neurotoxicity of grade3 (n=8,6.7％) &grade4 (n=0) versus21 cases of grade3 (n=21,21.4％) and grade4 (n=5,5.1％) in the control group.Statistically significant differences existed between grades 3 and 4 neurotoxicity (P ＜0.05).After 1 year of follow-up,the incidence of grade 1 of neurotoxicity was 2.5％ (n =3) in the experimental group versus 23.7％ (n =9) in the control group.And the inter-group difference was statistically significant (P ＜ 0.05).Lipoic acid plus sodium potassium magnesium,calcium and glucose injection can effectively prevent the occurrences of acute and chronic peripheral neurotoxicity associated with oxaliplatin.

Recent epidemiologic data indicate that metfomin has an anti-tumor effect.However,the underlying anti-tumor mechanisms remain unclear.MicroRNAs (miRNAs)can exhibit pro-oncogenic or anti-oncogenic effects by regulating the differentiation and proliferation of cells.In vitro studies show that metformin can regulate the expressions of multiple miRNAs which are closely associated with tumor development,a process possibly relating to the anti-cancer roles of metformin.

Objective To explore selection of the procedures in one stage urethroplasty for treatment of the coexistence of urethral strictures in anterior and posterior urethra.Methods Between January 2008 and December 2014, a total of 27 patients with coexist strictures simultaneously in anterior urethra and posterior urethra were treated in our hospital.The mean age was 38 years old (ranging 13-83 years old.Stricture etiology was secondary to lichen sclerosus in 2 patients, iatrogenic in 3 and posttraumatic in 22.The mean length of urethral stricture was 11cm (ranging 6-14cm).Two procedures for treatment of anterior urethral stricture, including augmentation of urethroplasty using penile skin flap was performed in 20 patients and augmentation of urethroplasty using lingual mucosa in 7.Three procedures for treatment of posterior urethral stricture, including non-transecting spongiosum end to end anastomosis of the two urethral ends was performed in 3 patients, end to end anastomosis of the two urethral ends was performed in 17 and substitution urethroplasty using different tissues was performed in reminder 7 patients.Of them, pedicle scrotal skin urethroplasty was performed in 2 patients and lingual mucosal graft urethroplasty in 5 patients.Results The patients were mean followed up 2.6 years (ranging 0.545.0 years) with an overall success rate of 88.9％ (24 of 27 cases).Complications developed in 3 patients (11.1％).Of the 17 patients with end to end anastomosis, urethral stricture developed respectively 4 and 6 months in 2 patients and voiding well after pedicle scrotal skin urethroplasty.Urethral pseudodiverticulum developed 9 months after pedicle penile flap urethroplasty in another patient and voiding well after urethroplasty.Urethrography showed patent urethra with adequate lumen in the remaining patients and mean urinary peak flows was 21.3 ml/s (ranging 14.2-37.9 ml/s).Conclusions Substitution urethroplasty using penile skin or oral mucosa was more good procedure for anterior urethral stricture during the treatment of the coexistence of urethral stricture in the anterior and posterior urethra.The treatment of posterior urethral stricture was based on the length of the stricture, local condition to make a choice between anastomotic urethral reconstruction and substitution urethroplasty using other tissue.

Objective To evaluate the clinical value of 3.0T magnetic resonance imaging (MRI) diffusion weighted imaging (DWI) on evaluation effect of neoadjuvant chemotherapy in advanced gastric cancer. Methods 3.0 T MRI DWI examination was performed in 42 cases of advanced gastric cancer diagnosed by gastroscopy and pathology, including 32 patients were examined with DWI both before and after chemotherapy. Lymph nodes of gastric cancer lesions and display ability of stomach were measured, and the area of the apparent diffusion coefficient (ADC) values in normal stomach and tumors were compared. ADC values were compared in the same patients before and after neoadjuvant chemotherapy and analyzed along with postoperative pathological examinations. Results In a total of 40 patients who received 74 DWI examinations, ADC values in tumor and lymph nodes were significantly higher than those in normal tissue. The ADC value in tumors was (1.348 ±0.278) ×10-3 mm2/s, and in 12 cases of stomach lymph node enlargement was (1.329±0.188) ×10-3 mm2/s. However, the average ADC value of normal stomach was (2.081± 0.189) ×10-3 mm2/s with significantly lower DWI than that of the former (P< 0.001). After chemotherapy, the ADC value in tumors was increased, which was (1.572 ±0.261) ×10-3 mm2/s (P< 0.001). After neoadjuvant chemotherapy, 16 patients received gastric cancer radical prostatectomy, and postoperative pathological TRG ratings of tumor were decreased with different extent. Tumor cell density (TCD) before treatment with an average of 4.45 ×10-5 / px2, which was downgraduated to 2.48 ×10-5 / px2 after chemotherapy and surgery. Negatively correlation between TCD values and ADC values were observed. Conclusion MRI DWI examination can effectively detect advanced stomach cancer and the associated lymph node enlargement. Comparison of tumor morphology and ADC values in advanced gastric cancer before and after neoadjuvant chemotherapy has clinical value in prognosis.

RAGE (receptor for advanced glycation end products) is a multiligand receptor on the cell surface.Ligand-RAGE inter-actions activate several signal transduction pathways that propa-gate cellular oxidative stress and inflammatory response.RAGE expressed on the CD4 + T cells has been identified as a central transduction receptor which affects the activation,proliferation, migration and differentiation of the cells.In addition,blockade of RAGE suppressed the development of multiple immune-related
disorders mediated by CD4 + T cells.These studies highlight the importance of RAGE and its ligands for CD4 + T cells.This arti-cle briefly reviews the role of RAGE and its ligands on the prolif-eration,migration and differentiation of CD4 + T cells and sum-marizes the related research progress.

The fibrosis can occur in many kinds of organs,and its sustained progress may lead to organ structural damage and functional decline,and even the organ failure,which threatens the human health and the life seriously.Adenosine is an endogenous purine nucleoside that can be generated in various tissues of the body and regulate a multitude of body functions via the combina-tion with four different kinds of G protein-coupled receptors.Re-cent studies have found that adenosine receptors play an impor-tant role in regeneration tissue and fibrosis process.To under-stand the processes may be helpful to the treatment of fibrosis diseases.This review makes a summary on latest research pro-gress of adenosine receptors in fibrosis diseases.

Objective To investigate the effect of dezocine combined with fentanyl in patients undergoing kidney transplantation on the quality of anesthesia and recover consciousness,as well as explore the preemptive analgesia effect of dezocine in renal transplantation.Methods Eighty patients undergoing allogeneic renal transplantation were randomly divided into control group (Ⅰ) and dezocine group (Ⅱ) (40 cases for each group).Patients in two groups were induced with midazolam 0.05 mg/kg,propofol 1-2 mg/kg,fentanyl 3 μg/kg,and cis-atracurium 2.5 mg/kg intravenously,and then they were incubated and given mechanical ventilation.Anesthesia was maintained with intravenous and inhalational anesthesia.1％-2％ sevoflurane had been inhaled until half an hour before the end of the surgery,while 1％ propofol 3-5 mg/kg/h and remifentanil 0.1-0.2 μg/kg/min had been pumped intravenously till the end of the surgery.2μg/kg fentanyl was infused in control group,while in dezocine group 0.1 mg/kg dezocine was intravenously infused before skin incision.The concentration of sevoflurane and the pump speed ofremifentanil were adjusted according to the depth of anesthesia.Changes of mean arterial pressure (MAP),heart rate (HR) and the pulse oximetry (SPO2) before anesthesia (T0),before skin incision (T1),5 minutes after incision (T2),5 minutes before extubation (T3) and 10 minutes after extubation(T4) were recorded.Extubation time,nausea,vomiting and the incidence of adverse reactions during recovery period were also recorded.Before leaving the operating room,VAS scale was used to assess the pain situation of patients.Results There were no significant differences in terms of MAP,HR and SPO2 at each time point between two groups (P ＞ 0.05).The VAS scores in fentanyl group was 1.76 ± 0.43,as same as that in dezocine group (1.84 ± 0.57,P =0.480 7).The incidence of adverse reactions including nausea,vomiting in fentanyl group and dezocine group were 22.5％ and 2.5％,and the difference was significant (x2 =7.314 3,P =0.007).The extubationtime after surgery in diesoline group [(12.21 ± 2.16) min] was significantly shortened than that in fentanyl group [(15.15 ± 2.25) min],P =0.000).Conclusion Dezocine preemptive analgesia is used in renal transplant patients in advance,and it can partly replace the same effect of fentanyl analgesia intensity,significantly shorten the extubation time,reduce the occurrence of awakening period adverse events such as of nausea,vomiting and restlessness.It is safe for renal transplant patients.
