Objective To explore the effects of electro-acupuncture combined with surface gastric pacing on gastrointestinal dysfunction for patients with spinal cord injury (SCI).Methods Seventy-five SCI patients with gastrointestinal dysfunction were divided randomly into an electro-acupuncture group (group A),a gastric pacing treatment group (group B) and a group for which electro-acupuncture was combined with gastric pacing (group C).There were 25 cases in each group.Members of group A were given 30 minutes of electro-acupuncture per day ; those of group B had 30 minutes of gastric pacing treatment twice per day ; group C was provided with both 30 minutes of electro-acupuncture and one 30-minute gastric pacing treatment per day.All of the interventions lasted ten days.Before and after the treatment,all patients were assessed using a clinical symptoms score and with electrogastrograms,and any adverse effects were observed.Results There was a significant improvement in upper abdominal pain and epigastric discomfort,bloating and early satiety,nausea,vomiting,as well as belching and loss of appetite in each group after treatment.Before treatment there was no significant difference in the average clinical symptom scores of the three groups.After treatment the values had decreased,and those of group C were significantly lower than group A or B.The average scores of groups B and A were not significantly different.The electrogastrogram results showed than after treatment there was significant improvement in N％ and T％ in groups A and B,and also significant improvement in N％,B％ and T％ in group C compared to before treatment.Group C's improvements were all significantly greater than those observed in groups A and B.Conclusion Electro-acupuncture or gastric pacing alone can give some improvement in gastrointestinal function and its electrophysiological indicators,but their combined effects are better than when either is used alone.

Objective To evaluate the diagnostic value of the combination of serum DKK1 (Dickkopf-1 )and P53 autoantibodies in patients with esophageal squamous cell carcinoma (ESCC).Methods Serum levels of DKK1 and P53 autoantibodies were measured by enzyme-linked immunosorbent assay (ELISA) for the 1 26 patients with ESCC and 60 normal controls.Receiver operating characteristics (ROC)was used to calculate the diagnostic efficiency.Results The serum levels of DKK1 and P53 autoantibodies were signifi-cantly higher in ESCC than those in normal controls [(673.09 ±343.82)pg/ml vs (362.05 ±1 48.07)pg/ml, Z =6.1 58,P <0.000 1 ;(0.398 ±0.546)vs (0.069 ±0.050),Z =3.832,P <0.000 1 ].ROC curves showed the optimum diagnostic cutoff for serum DKK1 was 588.77 pg/ml,with an area under curve (AUC)of 0.780 (95%CI:0.71 5 ~0.844,61 .9% sensitivity,95.0% specificity).Measurement of P53 autoantibodies demonstrated an AUC of 0.674 (95%CI:0.598 ~0.750,45.3% sensitivity,95.0% specificity).The com-bination of DKK1 and P53 autoantibodies yielded an AUC of 0.843 (95%CI:0.788 ~0.897,73.8% sensitiv-ity,95.0% specificity).In early-stage ESCC,combined detection of DKK1 and P53 autoantibodies improved the diagnostic power,with an AUC of 0.903 (95%CI:0.845 ~0.961 ,81 .0% sensitivity,95.0% specifici-ty).Conclusion Serum DKK1 and P53 autoantibodies can be used as potential diagnostic biomarkers for the ESCC.Combined detection of them might aid the early diagnosis of ESCC.

Objective To evaluate the application effect of teaching-picture archiving and communication system (T-PACS) in training image reading ability of eight-year-program students. Methods Sixty students were divided into two groups: control group (applying traditional teaching method) and experimental group (applying traditional teaching method and T-PACS) when doing clinical medical image reading ability training. Making multimedia teaching movie, clinical image reading teaching and establishing image database by T-PACS were used in experiment group. Mean-while, reading room was set up and classroom teaching and problem-oriented assignments were in-creased. Finally objective evaluation of image recognition ability and questionnaire were used to compare the teaching effect. Measurement data were expressed as x±s. Total scores of image reading were am-alyzed by t test. Full score rates were analyzed by X2 test. Results The results showed that the score of medical image reading ability was higher in experimental group (90.08±4.52) than in control group (86.92±4.68) (P=0.010). There were differences in respiratory and orthopedic full score rate (P=0.006;P=0.035). Most students thought that application of T-PACS could effectively improve the teaching and learning quality. Conclusions Application of T-PACS can improve the medical image reading ability of eight-year-program medical students and is worth further promoting.
