Objective To determine the median effective effect-site concentration (EC50 ) of remifentanil inhibiting responses to laryngeal mask airway insertion when combined with propofol in elderly male patients . Methods Thirty ASA physical status Ⅰ or Ⅱ male patients ,aged 65>yr ,with body mass index <30 kg/m2 , scheduled for elective transurethral resection of bladder tumor or prostate under general anesthesia ,were enrolled in this study .Anesthesia was induced with target-controlled infusion of propofol with a target plasma concentration (Cp) of 3 μg/ml .When Observer′s Assessment of Alertness/Sedation (OAA/S ) score ≤1 ,remifentanil target-controlled infusion was started with the initial target Cp set at 4.0 ng/ml . The concentration of propofol was adjusted until BIS value reached 55-65 ,and then the laryngeal mask airway was inserted .Modified Dixon’s up-and-down method was used to determine the Cp of remifentanil . Each time the Cp of remifentanil increased/decreased in the next patient depending on whether or not the response to laryngeal mask airway insertion occurred . The ratio of the two successive Cps was 1.2 .The response to laryngeal mask airway insertion was defined as development of coughing ,laryngospasm and/or body movement during insertion or within 3 min after insertion .The number of patients in whom inhibition of responses to insertion was effective/ineffective was recorded .The EC50 of remifentanil required to inhibit responses to laryngeal mask airway insertion and the 95% confidence interval when combined with propofol were calculated .Results The EC50 (95% confidence interval ) of remifentanil required to inhibit responses to laryngeal mask airway insertion was 1.86 (1.64-2.12) ng/ml when combined with propofol in elderly male patients .Conclusion The EC50 of remifentanil required to inhibit responses to laryngeal mask airway insertion is 1.86 ng/ml when combined with propofol in elderly male patients .

Objective To summarize our experiences of applying totally implantable venous access ports ( TIVAP) in chemotherapy for young children with malignant tumors.Methods Between December 2011 and May 2015, 50 young children with malignant tumors were implanted with TIVAP in Anhui Provincial Children's Hospital for chemotherapy.A retrospective review was conducted with their clinical records, focusing on success rate, clinical effect, and complications of TIVAP.Results The technical success rate was 100%with no intrao-perative complication such as puncture-related injury.In one case the device had to be adjusted through reopera-tion due to malposition of catheter tip.The port was removed in one case after 1 year due to infection.15 patients had the ports removed after the completion of chemotherapy.5 patients died due to the relapse and metastasis of tumor.29 patients are still using the port with no complications.Conclusion TIVAP is a safe device in young children, ensuring reliable vascular access for chemotherapy and improving patients'quality of life.

Objective To investigate the status of undergraduates′ sub-health and explore the relationship between personality traits and sub-health and the mediating role of self-harmony. Methods A total of 196 undergraduate nursing students in Tianjin University of Traditional Chinese Medicine were investigated by Sub-health Self-rating Scale (SSS), Self Consistency and Congruence Scale (SCCS) and Eysenck Personality Questionnaire Short Scale. Results The the total scores of the undergraduate nursing students′personality traits, self-harmony and sub-health were 22.71±4.90, 102.74±14.41, 182.54± 31.76. The neuroticism and extroversion of personality traits were significantly correlated with self-harmony and sub-health (P<0.01). Neuroticism had a significant prediction on self-harmony (β=0.37, P<0.01) and sub-health (β=-0.64, P<0.01), after controlling self-harmony, the prediction on sub-health was reduced, but still significant (β=-0.56, P<0.01);extroversion had a significant prediction on self-harmony (β=-0.27, P<0.01) and sub-health (β=0.54, P<0.01), after controlling self-harmony, the prediction on sub-health was reduced, but still significant (β=0.46, P < 0.01). Conclusions The sub-health status of undergraduate nursing students was not optimistic. Nursing students′ personality traits of psychoticism, extroversion, which directly impact on the health status, and through self-harmony indirectly affect their health level, self-harmony played a intermediary role between personality traits and sub-health.

Objective To determine the perioperative risks of partial hepatectomy by determining the preoperative liver functional reserve in patients with hepatocellular carcinoma (HCC),and to compare the model for end-stage liver disease (MELD) score with the Child-Pugh classification in predicting prognosis.Methods We reviewed the clinical data of 202 patients with HCC who underwent partial hepatectomy.The MELD score and the Child-Pugh classification were determined preoperatively.Results The incidence of postoperative liver dysfunction happened in 44.0％ of Child A patients,50％ in Child B patients,41.6％in patients with a MELD score below 14,and 91.7％ in patients with a MELD score of ＞ 14.The difference between the rates of postoperative liver dysfunction in patients with a preoperative MELD score above 14 and below 14 was significant (P ＜ 0.05),while that between patients with Child-Pugh A and B was insignificant (P ＞ 0.05).The incidences of postoperative liver dysfunction in patient with a MELD ＜ 8,8 ≤ MELD ≤ 14,MELD ＞ 14 were 38.2％,57.6％ and 91.7％,respectively,indicating that there was a positive co-relationship between the MELD score and the incidences of liver dysfunction.The Spearman rank correlation test showed the MELD score was significant correlated with the Child-Pugh score (r =0.404 ; P ＜ 0.05).The areas under the ROC curves of the MELD score and the Child-Pugh score were 0.703 and 0.587 (P ＜ 0.05).Conclusions The MELD score predicted postoperative liver dysfunction more accurately than the Child-Pugh classification.HCC patients undergoing partial hepatectomy with a preoperative MELD score ＞ 14 had a high perioperative risk.To ensure the safety of partial hepatectomy,HCC patients with a preoperative MELD score ＞ 14 requires active preoperative preparation,bringing the score near to or less than 14.

Objective To understand the epidemiological characteristics of brucellosis among risk population and analysis risk factors, and to provide a reference basis for prevention and treatment of brucellosis. Methods Retrospective survey method was used to collect information on brucellosis and epidemiologically confirmed cases in Tongxiang City from 2010 to 2015. The employees gender, age, occupation, job seniority, contact area, contact history to abortion cub and with or without protection measures were analyzed by single factor and multiple factors analysis, calculate odds ratio (OR) and 95%confidence interval (CI). Results Totally 1 450 people were investigated and 43 were confirmed positive (2.97%),new cases were 37 with joint pain 86.49% (32/37), low temperature 81.08%(30/37), and weak 62.16%(23/37) as the main body symptoms. Most people were infected in the summer season, accounted for 8.07%(18/223); female cases were relatively higher, accounted for 5.38% (12/223);people younger than 30 years old had the highest positive rate 24.14%(7/29);people working in the processing of animal products had the highest positive rate 6.42%(12/187). The employees gender, age, the types of work, the job seniority, the district distribution and the season were all related to the prevalence of the disease (all P< 0.05) analyzed by Chi-square test and Fisher's exact probability method. By single factor analysis, gender (male, OR =0.397, 95%CI:0.178-0.884), age (31-60 years old, OR = 0.254, 95%CI:0.081-0.796), and types of work (processing personnel, OR =3.211, 95%CI: 1.424 - 7.238) and contacting young animal (OR = 3.544, 95%CI: 1.729 - 7.264), practitioners operating tool (OR=0.231, 95%CI:0.070-0.766) were related to the prevalence of the disease;by multiple factors analysis, contacting young animal (OR=5.198, 95%CI:2.078-13.000) was a risk factor for brucellosis abortion, and practitioners operating tools (OR = 0.161, 95%CI: 0.045 - 0.577) were brucellosis protective factors such as wearing gloves . Conclusion We suggest to strengthen health education and health promotion in professional key populations, do a good job in the epidemic monitoring and promote occupational protection awareness, and decrease the infection of brucellosis.

Objective To discuss the clinical efficacy of internal fixation assisted by thoracoscope in treatment of rib fractures.Methods The study enrolled 180 patients with rib fractures associated with thoracic deformity hospitalized from July 2010 to June 2013.Ninety out of the patients were operated on by thoracoscope-assisted internal fixation (operation group),and the remaining 90 fractures were treated non-operatively (non-operation group).Clinical markers recorded were duration of pain,time of ventilator use,hospital length of stay and complications.Patient mental health was measured with self esteem scale (SES).Patient mobility was evaluated at follow-up.Results Between operation and non-operation groups differences were observed in duration of pain [(3.1 ± 1.0)d vs (8.9 ± 1.2) d],time of ventilator use [(3.0 ± 1.0) d vs (4.8 ± 1.0) d] and hospital length of stay [(10.0 ± 1.1) d vs (15.8 ± 1.0) d] (P ＜ 0.01).SES in operation group was (28.3 ± 2.1) versus (24.4 ± 3.3) points in non-operation group (P ＜ 0.01).No major complications occurred in operation group,but there were 20 pleural effusion,15 severe thoracic collapse or deformity,14 lung infection,10 refractory chest pain and 2 upper limb dysfunction in non-operation group (P ＜0.01).Two patients presented mobility limitation in operation group,but 12 had evident loss of mobility in non-operation group (P ＜0.01).Conclusions Thoracoscope-assisted internal fixation is effective to accelerate the pace of recovery,relieve pains,reduce complications and thus can be a priority method for treatment of rib fractures.

Objective To compare the expressions of Beclin 1 and its 11 interacting proteins in subcutaneous fat and visceral fat,and to observe the expressions of these genes in 3T3-L1 adipocytes differentiation process.Methods In 3T3-L1 adipocytes,cells were harvested at day 0,2,4,6,8 in differentiation process,and then proteins or mRNAs were obtained and followed with Western blot and realtime PCR.Mice tissue proteins or mRNAs were detected with Western blot and realtime PCR.Results In 3T3-L1 adipocytes differentiation process,expressions of LC3,Beclin 1,and TNFAIP3 continued to rise,expression of BIRC5 was high to low,FEZ1 continued at a low level.In mice,expressions of LC3,Beclin 1,YWHAQ,FEZI,BAD,WAC,TNFAIP3,and GOPC in visceral fat were significantly higher than those in subcutaneous fat,while expression of SLAMF1was higher in subcutaneous fat.Conclusion Autophagy plays an important role in 3T3-L1 differentiation process and may be tissue-specific in visceral fat and subcutaneous fat.
