Objective To determine the appropriate dosage of parexoxib sodium for postoperative analgesia in different age children with day surgery.Methods One hundred and eighty ASA Ⅰ children aged 1-12 yr scheduled for day surgery undergoing sevoflurane anesthesia combined with lateral inguinal regional blockade were divided into 3 groups according to age ( n =60 each):group 1-3 yr (group Ⅰ ),group 4-6 yr (group Ⅱ ) and group 7-12 yr (group Ⅲ).Eeach group was randomly divided into 2 sub-groups( n =30): parecoxib sodium 0.5 mg/kg (sub-group A) and parecoxib sodium 1.0 mg/kg (sub-group B).Sub-groups A and B received iv injection of paracoxib sodium 0.5 or 1.0 mg/kg respectively immediately at skin incision.Analgesic effect was evaluated by FLACC score (group Ⅰ ),CHEOPS score (group Ⅱ ) and VAS scroe (group Ⅲ) at 6(T1 ),12(T2 )and 24 h (T3)after operation.The effective analgesia was defined as FLACC score≤3,CHEOPS score≤7 or VAS score≤ 3.Side effects were also observed.Results Compared with sub-group B,FLACC score was significantly increased at T1 in sub-group Ⅰ -A ( P ＜ 0.01 ).There was no significant difference in CHEOPS score or VAS score between sub-groups Ⅱ -A and Ⅱ -B,and between sub-groups Ⅲ-A and Ⅲ-B (P ＞ 0.05).The incidence of effective analgesia was 97％ in group Ⅰ (93％ in group sub-group Ⅰ -A,100％ in sub-group Ⅰ -B),100％ in group Ⅱ and 93％ in group Ⅲ (97％ in sub-group Ⅲ-A,90％ in sub-group Ⅲ-B).There was no significant difference in the incidence of side effect between sub-groups Ⅰ -A and Ⅰ -B,between sub-groups Ⅱ -A and Ⅱ -B,and between sub-groups Ⅲ-A and Ⅲ-B ( P ＞ 0.05).Conclusion Parecoxib sodium 1.0 or 0.5 mg/kg can be used in postoperative analgesia in children aged 1-3 yr or 4-12 yr with day surgery respectively.

Toxoplasmosis, a neglected tropical disease caused by the protozoan parasite Toxoplasma gondii, occurs throughout the world. Human T. gondii infection is asymptomatic in 80% of the population; however, the infection is life-threatening and causes substantial neurologic damage in immunocompromised patients such as HIV-infected persons. The major purpose of this study was to investigate the seroprevalence of T. gondii infection in subjects infected with HIV/AIDS in eastern China. Our findings showed 9.7% prevalence of anti-T. gondii IgG antibody in HIV/AIDS patients, which was higher than in intravenous drug users (2.2%) and healthy controls (4.7%), while no significant difference was observed in the seroprevalence of anti-Toxoplasma IgM antibody among all participants (P>0.05). Among all HIV/AIDS patients, 15 men (7.7%) and 10 women (15.9%) were positive for anti-T. gondii IgG antibody; however, no significant difference was detected in the seroprevalence of anti-Toxoplasma IgG antibody between males and females. The frequency of anti-Toxoplasma IgG antibody was 8.0%, 13.2%, 5.5%, and 0% in patients with normal immune function (CD4+ T-lymphocyte count ≥500 cells/ml), immunocompromised patients (cell count ≥200 and <500 cells/ml), severely immunocompromised patients (cell count ≥50 and <200 cells/ml), and advanced AIDS patients, respectively (cell count <50 cells/ml), while only 3 immunocompromised patients were positive for anti-T. gondii IgM antibody. The results indicate a high seroprevalence of T. gondii infection in HIV/AIDS patients in eastern China, and a preventive therapy for toxoplasmosis may be given to HIV/AIDS patients based on CD4+ T lymphocyte count.

Objective To investigate the relationship between the professional burnout status and the personality trait of duty nurses , and to effectively alleviate the professional burnout of duty nurse , and provide practical basis to the quality management of nursing personnel .Methods Ninety five duty nurses were investigated with the Chinese version of Maslach Burnout Inventory ( MBI ) and the Eysenck Personality Questionnaire ( EPQ ) .We studied the professional burnout status and the personality trait distribution , and analyzed the relationship between them .Results The detection rate of the professional burnout was 86 .32%. The rate of degree of burnout at low , medium, high level were 35.79%, 32.63%, 17.89%, respectively.The personality trait had an important impact on the burnout level (F=11.940,P<0.01).Conclusions The group of duty nurses is at a high level of professional burnout .And their personality trait can predict the professional burnout.We should pay attention to the relevant administrative and management interventions .
