Chinese Journal of Behavioral Medicine and Brain Science 2011;20(7):602-604
Objective To investigate the role of sex chaperone on self-acceptance,anxiety,depression and coping strategy in stable phase extensive burn patients'.Methods According to the different role of accompanies,the extensive burn patients in stable phase were divided into sex chaperone accompany groups(treatment group)and non-sex chaperone accompany group(control group).They were assessed by self-acceptance questionnaire(SAQ),self-rating anxiety scale(SAS),self-rating depression scale(SDS)and medical coping modes questionnaire(MCMQ).The results were statistically analyzed.Results The treatment group patients'results are as follows:SAQ total score was(41.37±6.98),self-acceptance factor score was(20.56±4.87),self-evaluation factor score was(22.35±5.82),MCMQ facing factor score was(21.80±4.07),MCMQ avoiding factor score was(22.35±5.82).The results of treatment group patients were significantly higher than those in control group,it had significant differences(P<0.05 or P<0.01);while the treatment group patients'scores of SAS,SDS,MCMQ yield factor were significantly lower that those in the contorl group.The self-acceptance factor score appeared to be negative correlation with the SAS score,SDS score and MCMQ yield factor score,while to be positive correlation with MCMQ facing/avoiding factor score.Conclusion Sex chaperone'accompany can eliminate the extensive burn patients'tension and the effect of adverse psychological factors,and meet family love needs of patients,then improve the level of patient self-acceptance,reverse the negative emotion of patients,and guide patients in a positive way to face the disease.

The pharmacokinetics of ketamine were studied in 8 preschool children,aged 3.5~6 years. The ketamine was administrated by I. V. infusion at a dose of 3mg?kg~(-1) in one hour constantly. The plasma concentrations of ketamine were measured by high performance liquid chromatography. The disposition of intravenous infusion with ketamine could be described by two-compartment open model, and the variables of pharmacokinetics of ketamine were as follows: T_(1/2?)=0.15?0.04 hours,T_(1/2?)=2.84?0.44 hours,Cl=0.34?0.06L?kg~(-1)?h~(-1), AUC=9.21?1.00mg/L?h, and V_d=0.66?0.29 L?kg~(-1). This suggests that intravenous infusion of ketamine at 3mg?kg~(-1)?h~(-1) is safe for the maintenance of general anesthesia in preschool children, attention must he paid to the children anesthetized with long period of ketamine infusion because recovery may be delayed due to the prolonged elimination half-life.

Objective: To determine the influence of ?-hydroxybutyric sodium (7-OH)on the pharmacokinetics of ketamine infusion in preschool children. Method: Sixteen patients were randomly assigned to group Ⅱ (Ketamine) and group Ⅱ (Ketamine plus ?-OH). After trachea intubation,0.05% ketamine was infused in both groups at 3mg?kg~(-1)?h~(-1) and ?-OH 125mg?kg~(-1) only in group Ⅱ. The plasma concentration of ketamine was measured using high performance liquid chromatography. Pharmacokinetic parameters were calculated using 3P_(87) software composed by Chinese Pharmacologic Society. Result: In both groups,pharmaeokinetics could be descrided as two-compartment open model. The T_(1/2)? and the Cl differ between group Ⅰ and group Ⅱ (P

A new biosensor was prepared based on conductive polymer poly ( 3 , 4-ethylenedioxythiophene ) ( PEDOT) and 1-pyrenebutanoic acid ( PBA) through π-π stacking, as well as hematin associated with PBA through coordinate bonds of Zr4+ and carboxyl group. Its stability and sensitivity were examined by cyclic voltammetry ( CV) , electrochemical impedance spectroscopy ( EIS) and current-time ( i-t) method. A pair of well defined and quasi-reversible redox peaks was observed when GCE/PEDOT/PBA/hematin was tested by CV in PBS without oxygen. The electron transfer rate constant was estimated to be 4. 8 s-1 . Results indicated that the PEDOT film enhanced the electron transfer process of hematin. When the i-t method was used to detect the response of biosensor to catechol with different concentrations, it displayed a linear response for the reduction of catechol in the range of 0. 5-200 μmol/L. The linear equation was i=0. 018C+0. 006 ( R=0. 9998), and the detection sensitivity was 0. 258 μA (μmol/L· cm2) with a detection limit of 0. 33 nmol/L (S/N=3). The results illustrate that the GCE/PEDOT/PBA/hematin biosensor is very sensitive and stable.

Objective To establish two-dimensional electrophoresis profiles of laryngeal squamous carcinoma tissue with high resolution and reproducibility. Methods The total protein of well-differentiated or poorly-differentiated laryngeal cancer tissue was separated by means of immobilized pH gradient-based two-dimensional gel electrophoresis (2-DE). The differential expression protein was analyzed by using ImageMaster 2D analysis software. Results We obtained fine resolution, reproducible 2-DE patterns of well-differentiated and poorly-differentiated laryngeal squamous carcinoma. Differential expression protein spots were defined in 2-DE gels. Thirteen protein spots were preliminarily identified, among which seven proteins were upregulated in well-differentiated laryngeal cancer tissue, six were downregulated. Conclusion The expression map of proteomics was established for well-differentiated and poorly-differentiated laryngeal cancer, which was of significant difference between them. Laryngeal cancer proteome might reflect the underlying pathological state.

0.05). The incidence of restenosis and major adverse cardiovascular events were significantly less in the hyperbaric oxygen group than that in the control group (6.67% vs 22.58% for restenosis, and 8.82% vs 38.24% for major adverse cardiovascular events; P0.05). No severe adverse effect was found during hyperbaric oxygen therapy in the hyperbaric oxygen group. Conclusion Hyperbaric oxygen therapy is effective and safe in preventing restenosis after intracoronary stenting.

Objective:To investigate the relationship between serum fibroblast growth factor 21/23 level, trauma severity and prognosis in middle-aged and older adult patients with traumatic fracture.Methods:A total of 126 middle-aged and older adult patients with traumatic facture who received treatment in the Second People's Hospital of Lishui, China between June 2017 and June 2019 were included in the study group. Fifty healthy controls who concurrently received physical examination in the Second People's Hospital of Lishui were included in the control group. The study group was divided into five subgroups according to relevant criteria: mild, moderate, severe, poor prognosis and good prognosis. The levels of C-reactive protein (CRP), procalcitonin (PCT), FGF21 and FGF23 were measured.Results:On admission, serum CRP, PCT, FGF23, FGF2 levels in the study group were (19.18 ± 5.66) mg/L, (0.71 ± 0.20) μg/L, (79.75 ± 18.62)μg/L,(52.10 ± 16.34) μg/L, respectively, and they were significantly higher than those in the control group [ (7.60 ± 2.61) mg/L, (0.30 ± 0.11) μg/L, (40.18 ± 10.33) μg/L, (30.11 ± 10.19) μg/L, t = 18.888, 17.750, 18.336, 11.032, all P < 0.001). On admission, serum CRP, PCT, FGF23, FGF2 levels in the study group were (19.18 ± 5.66) mg/L, (0.71 ± 0.20) μg/L, (79.75 ± 18.62) μg/L, (52.10 ± 16.34) μg/L, respectively, and they were significantly increased at 1 day [(21.59 ± 4.53) mg/L, (0.79 ± 0.22) μg/L, (83.85 ± 19.07) μg/L, (55.18 ± 16.55) μg/L, t = 3.72, 3.29, 1.56, 1.56, P < 0.05, P < 0.05, P = 0.122, P = 0.122] and 3 days after surgery [(23.15 ± 3.16) mg/L, (0.80 ± 0.24) μg/L, (88.11 ± 19.80) μg/L, (59.70 ± 16.07) μg/L, t = 6.65, 3.12, 3.59, 3.77, all P < 0.05] , and significantly decreased at 7 days after surgery [(14.35 ± 4.02) mg/L, (0.52 ± 0.16) μg/L, (50.06 ± 15.50) μg/L, (32.18 ± 12.52) μg/L, t = 8.31, 8.58, 13.77, 11.11, all P < 0.001]. On admission, there were significant differences in serum CRP, PCT, FGF23, FGF21 levels between mild, moderate and severe groups ( F = 25.087, 15.851, 15.831 and 12.645, all P < 0.001). On admission, serum CRP, PCT, FGF23, FGF21 levels in the poor prognosis group were significantly higher than those in the good prognosis group ( t = 5.757, 4.984, 3.189 and 4.006, all P < 0.001). The receiver operating characteristic curve (ROC) analysis results showed that serum CRP, PCT, FGF23, FGF21 levels in patients with traumatic fracture on admission had a certain value in the prediction of poor prognosis. Combined detection of these four indexes had the highest value, with AUC (0.95 CI) of 0.877 (0.783-0.982). Conclusion:Serum FGF21 and FGF23 levels have a certain value in the prediction of severity and prognosis of traumatic fracture in middle-aged and older adult patients.
