Objective To evaluate the applied value of multislice spiral CT multiplanar reconstruction in diagnosing the trauma oforbit. Methods 40 patients with trauma of orbit underwent multislice spiral CT scan, the thickness of slices was 2 mm and collimator was 0.75 mm. Multiplanar reconstruction (MPR) and free angle parallel ranges reconstruction (PRR) were performed. CT findings of orbital trauma were analysed. The result passes through the surgery and the clinical confirmation.Results 14 cases with radiopaque foreign in orbit comfirmed by operation were accurately localized by MPR and PRR, but 6 cases were misdiagnosed by conventional CT. There were 21 cases with fracture of orbital wall, of them, 9 cases were not detected or partially misdiagnosed by plain CT. The damage of eye musculus rectus was in 16 cases, 6 cases were diagnosed by MPR+PRR. There were 16 cases with eyeball damage, of them , 4 cases detected by conventional CT difficultly, but they identified by MPR and PRR. The damage of optic nerve was in 5 cases, 4 cases were not discovered by conventional CT. Conclusion MPR and PRR are of important value in evaluating the orbital trauma.

Objective To evaluate the effect of comprehensive intervention measures on preventing and controlling surgical site infection (SSI)in patients undergoing total abdominal hysterectomy.Methods Patients undergoing total abdominal hysterectomy in a hospital between January 2011 and December 2014 were investigated retrospec-tively,patients in 2011 were as control group,from January 2012,a prospective monitoring on SSI was initiated, comprehensive intervention measures were taken,patients between January 2012 and December 2014 were as inter-vention group,SSI before and after the intervention was compared.Results A total of 1 052 patients undergoing to-tal abdominal hysterectomy were investigated,267 cases were monitored before intervention,25 patients (9.36%) developed healthcare-associated infection (HAI),12(4.49%)of whom were with SSI;785 cases were monitored af-ter intervention,13 (1 .66%)of whom were with SSI,incidence of SSI in 2012,2013,and 2014 were 2.31 %, 1 .89%,and 0.77% respectively,there was a decreasing tendency(χ2 =7.30,P <0.01 ).Conclusion Prospective monitoring on SSI and comprehensive intervention can reduce the incidence of SSI in patients undergoing total abdominal hysterectomy.

OBJECTIVE: To provide reference for rapid and effective first aid to mine disaster before hospitalization. METHODS: The status quo of emergent rescue for mine disaster in China was reviewed. The key to rescue, main countermeasures and necessary drug of first aid before hospitalization were analyzed according to the characteristics of mine disaster and troubles of medical rescue. RESULTS & CONCLUSIONS: Ambulance corps cooperated with medical staffs to set ICU at disaster site. Scientific rescue provided by professional team can improve survival rate. Meanwhile, a perfect mine disaster rescue system should be set up.

OBJECTIVETo evaluate the effect of the oral-appliance in the treatment of ED induced by obstructive sleep apnea-hypopnea syndrome (OSAHS).

METHODSThis study included 40 cases of OSAHS-induced ED. Based on the apnea-hyponea index (AHI) and lowest SaO2, we divided the patients into groups A (AHI < or = 30/h and lowest SaO2 > or = 80%) and B (AHI > 30/h and lowest SaO2 < 80%), and treated them with the oral-appliance for 3 months, followed by evaluation of the therapeutic effect using polysomnography, IIEF-5 questionnaire and Sexual Encounter Profile (SEP) diaries.

RESULTSThirty-seven of the patients accomplished the treatment, 16 in group A and 21 in group B. Compared with the baseline, the AHI was significantly decreased in both groups A (21.4 +/- 7.3 vs 14.2 +/- 6.6, P < 0.05) and B (51.4 +/- 9.5 vs 29.7 +/- 8.1, P < 0.05) after treatment, the IIEF-5 scores increased, even more remarkably in B than in A (3.36 +/- 2.48 vs 1.12 +/- 1.27, P < 0.05). The positive rates of SEP2 and SEP3 were markedly lower in A than in B (37.5% vs 76.2% and 25.0% vs 61.9%, P < 0.05).

CONCLUSIONThe oral-appliance can improve the erectile function of OSAHS-induced ED patients, particularly for those with severe OSAHS.

Objective: To study the right hemisphere function state of NLD children. Methods: Adapting tachistoscopic vision and Benton Revised Visual Retention Test (VRT), three groups involving 20 children each were studied. Results: Under the tachistoscopic vision, NLD children achived poorly in recognition of nonverbal stimulus; and they do worse also in VRT test, with more errors of omission and distortion. Conclusion: Compared with normal children, the function of NLD children's right hemisphere is relatively weaker.

The"Experiencing teaching"is a students-centered and task-based teaching approach,from which students can apply what they learn to practice through their own experiences in classes.Using experiencing teaching in medical psychology,we get good teaching effects.

Objective: To explore the personality traits in the people at high risk for schizophrenia.Methods: 188 individuals at high risk for schizophrenia,and 321 normal controls were assessed by Schizotypal Personality Questionnaire(SPQ).Results: The score of negative schizotypal dimension in SPQ in the individuals at high risk was higher than in the normal controls.Conclusion: The people at high risk for schizophrenia have negative schizotypal personality traits which may represent a genetic endophenotype for schizophrnia.

Objective To research the optimal test condition for determining TVOC in air based on GB 50325-2001 Code for Indoor Environmental Pollution Control of Civil Building Engineering. Methods Seven kinds of standard gas (benzene, toluene, ethylbenzene, p-dimethylbenzene, m-dimethylbenzene, ethenylbenzene and o-dimethylbenzene) were injected into Tenax-TA sampling tube, then heated for different time and pyrolyzed for different time. Results Tenax-TA sampling tube was heated for 30 seconds and pyrolyzed for 90 seconds. The recovery rate of seven kinds of compounds was more than 90%. Relative standard deviation was less than 10%. Conclusion The optimal test condition for determining TVOC in air has been presented in this paper. The precision and sample recovery rate will meet the requirement of indoor air quality standard annex A Indoor Air Monitoring Technology.

Twenty-six total intravenous anesthesia was performed in 23 ASAⅡorⅢpatients with various advanced malignancies undergoing whole body hyperthermia (WBH). Their age ranged from 32 to 67 yrs and body weight between 42 and 77 kg. The patients had no hypertension, coronary artery disease or diabetes mellitus. Anesthesia was induced with midazolam 5-10 mg, fentanyl 0.1 mg, propofol 1.5-2.5 mg?kg-1 and vecuronium 0.12 mg?kg-1 and maintained withⅣinfusion of midazolam (0.08-0.16 mg?kg-1?h-1), remifentanil (0.05-0.15?g?kg-1?h-1) and vecuronium (0.08-0.15 mg?kg-1?h-1). The patients were mechanically ventilated (VT = 8-12 ml?kg-1, RR= 10-18 bpm, FiO2 = 1.0) after tracheal intubation. PETCO2 was maintained at 35 mm Hg. ECG, MAP, HR, CVP, SpO2 , PETCO2 , peak airway pressure, VT, RR, minute ventilation (MV), urine output, core temperature (lower esophageal and naso-pharyngeal) and surface temperature were continuously monitored. Swan-Ganz catheter was placed in 15 patients. MPAP, PCWP and cardiac output (CO) were measured and Qs/Qt, cardiac index (CI) and stroke index (SI) were calculated. WBH was induced in an ultra-red radiation hyperthermic cabin (type ET-SpaceTM-1) and was divided into 3 phases:Ⅰwarming phase (lower esophageal temperature increased gradually to 41.8℃) ;Ⅱhyperthermic phase (lower esophageal temperature was maintained at 41.8℃for 1 h) andⅢcooling phase (core temperature was gradually decreased to 38.5℃without any cooling measures). Blood samples were taken from artery and Swan-Ganz catheter 15 min after induction of anesthesia (baseline), at 39℃, 40℃, 41℃and 41.8℃during warming phase, at the late hyperthermic phase and at 40℃and 38.5℃during cooling phase for blood gas analysis, determination of blood electrolytes and sugar. As the temperature was increasing, HR, CI, SI, CVP, MPAP, PCWP, Qs/Qt and peak airway pressure were gradually increased while MAP, PaO2 , pHa, BE and blood glucose and K+ were decreasing during warming phase (Ⅰ). These changes reached the peak levels at the late period of hyperthermic phase (Ⅱ) and then gradually returned to baseline during cooling phase (Ⅲ) . Vasoactive drugs and fluid infusion including crystalloid and colloid were needed to maintain hemodynamic stability in 69% patients. Acidosis had to be corrected in 54% patients. Severe hypotension and pulmonary edema occurred in 4 patients. Continuous hemodynamic monitoring, respiratory support, maintenance of circulatory stability and correction of acidosis and hypokalemia were the key factors in the management of patients during WBH.
