Objective To explore the value of contrast-enhanced ultrasonography (CEUS) in diagnosis of esophagogastric varices (EGV) compared with color Doppler flow imaging (CDFI). Methods CDFI and CEUS were performed on 23 variceal patients based on the B mode ultrasound examination. The blood flow of esophageal varices (EV) or gastric varices (GV) displayed with CDFI and CEUS were compared. Results The flow signal demonstration rate of EV with CDFI and CEUS was 42.11% (8/19) and 73.68% (14/19), while that of GV with CDFI and CEUS was 76.47% (13/17) and 94.12% (16/17), respectively. CEUS displayed the flow signal of EV better than CDFI did (χ~2=4.17, P＜0.05), but the flow signal demonstration rate of GV was not significantly different (χ~2=1.33, P＞0.05). Conclusion CEUS can be used more extensively in clinic practice for diagnosis of EGV.

Objective To compare healing effects of surgical incisions using 635 /808 nm dualwavelength semiconductor laser and He-Ne laser irradiation.Methods 168 cases of non-malignant tumor surgery patients were randomly divided into 2 groups:test group including 83 cases which were treated on the surgical incisions by laser irradiation of the semiconductor illumination with low-intensity power; positive control group with 85 cases treated with He-Ne laser.Observation was carried out on incision healing by the clinic manifestations including redness,heat,swelling,pain,exudation,wound open,adverse event and the incision length offset.Results There was no significant difference between experimental group and the control group on incision healing (P＞0.05).Conclusions The treatment efficacy of the dual-wavelength semiconductor laser on surgical incisions healing is similar with that of the He-Ne laser.

Objective To discuss the relationship between peptic ulcer in children and food-specific IgG, and to evaluate the effect of avoiding the intolerant food on treatment of peptic ulcer. Method Fourteen kinds of food specific IgG in 69 cases of peptic ulcer were tested by ELISA. The patient′s intolerance to different foods and its relationship with age , sex and different ulcer were analyzed. The efficacy of avoiding the intolerant food was assessed after 8 weeks. Results Total positive of food-specific IgG in children with peptic ulcer was 94.2%. For preschool children, the highest intolerance rates were in milk and eggs; for school-age and adolescence children, the highest intolerance rate was in eggs. As the age increases, kinds of intolerant food increased too. Ulcer healing rate in observation group was higher than that in the control group after 8 weeks. Conclusions High positive percentage of food- specific IgG was found in children with peptic ulcer , indicating a possible correlation of peptic ulcer and food-intolerance. Kinds of intolerant food correlates with the age group , but not with sex and ulcer sites. Avoiding the intolerant food may increase ulcer healing rate.

ObjectiveTo explore the effect of early rehabilitation on patients with severe traumatic brain injury.Methods89 patients with severe traumatic brain injury were divided randomly into the treatment group (49 cases) and control group (40 cases). All patients of two groups were treated with routine nursing, dehydrated drug, brain protective therapy and alimental therapy, and measures of preventing complications. While, the patients of the treatment group were added with motor and cognitive rehabilitation, mainly physical therapy, combined with occupational therapy, psychotherapy and speech therapy. All patients of two groups were evaluated with scores of activities of daily living (ADL), Disability Rating Scale (DRS), Fugl-Mayer Assessment (FMA), Mini-mental status examination (MMSE), three class balance scale before and after treatment.ResultsThe scores of ADL, DRS, FMA and balance function of the patients in the treatment group were significantly different from that of the control group after treatment ( P<0.05).The MMSE scores of two groups had no significantly difference after treatment ( P>0.05).ConclusionEarly rehabilitation can improve the brain function of the patients with severe traumatic brain injury, patients' living quality and ADL.
