Objective To evaluate CT in the diagnosis of small bowel obstruction in children. Methods Thirty one cases with small bowel obstruction manifestations on CT and plain radiograph were analysed. The age ranged from 9 months to 14 years, male 17 cases, female 14 cases. There were 29 acute small bowel obstructions, and 2 chronic obstruction. Seven cases had history of previous abdominal operation. Results Corred diagnosis was made in 19 cases and 29 cases respectively by plain film and CT. The accurate etiologic diagnosis could be made by CT in 18 cases, including small bowell stone 4 cases, intussusception, 5 localized infection and adhesion 6 intraluminal bowel duplication, 1 congenital umbilical hernia, congenital malrotation of the intestine 1 case.Combined with history of abdominal operation the accurate CT etiologic diagnosis increased to 25 cases.There were 4 CT false negative cases and 2 plain film false negative cases. Conclusion The CT is obviously superior to plain radiograph in detecting strangulation and gas in bowel wall,better dilineating the transitional segment of bowel stenosis thereby demonstrating the case of obstruction which is very helpful for clinical management.

Obesity as a global issue is a serious threat to children's health.To control childhood obesity must begin with effective preventions.Most studies have found that breast milk can protect against childhood obesity.It is recommended that children should be exclusively breastfed for at least 4-6 months.The duration of breastfeeding has some negative correlation with the prevalence of childhood obesity.Increasing the duration of breastfeeding can properly decrease the risk of childhood obesity.

Objective To explore the role of apparent diffusion coefficient (ADC) value of diffusion-weighted imaging (DWI) in the differentiation between benign and malignant bone tumors. Methods Echo planar imaging DWI was performed in 18 patients with benign tumor or tumorous lesion and 26 patients with malignant tumor of bone. Three b-values (0, 500 and 1000 s/mm2) were applied. The lowest, highest, and whole ADC values were measured for each lesion, respectively. Results The lowest ADC values of benign bone tumor[ mean( 1.28±0. 49) ×10-3mm2/s ] were significantly higher than that of malignant tumor [ mean ( 0. 92±0. 35 )×10-3mm2/s, t = 2. 839, P < 0. 01 ]. The whole ADC values of benign bone tumor [ mean (1.62±0. 51 ) ×10-3mm2/s] were significantly higher than that of malignant tumor [ mean ( 1.21±0. 36) ×10-3mm2/s, t = 3. 092, P < 0. 01 ]. However, there were much overlapping between benign and malignant bone tumor in the lowest and whole ADC values. There was no significant difference for the highest ADC values between benign [. Mean ( 2. 02±0. 55 )×10-3mm2/s] and malignant bone tumor[ mean( 1.71±0. 65 ) ×10-3mm2/s, t = 1. 669, P > 0. 05 ]. Excluding cases of bone cyst and aneurismal bone cyst, the lowest, highest, and whole ADC values of benign bone tumor was (1.11± 0. 31 )×10-3mm2/s, ( 1.88±0. 49)×10-3mm2/s, and( 1.45±0. 35 )×10-3mm2/s, respectively. There was no significant difference for the lowest, highest, or whole ADC values between benign and malignant bone tumor (t = 1. 728, 0. 964, and 2. 012, respectively, P > 0. 05). Conclusion ADC value is useless for the differentiation between benign and malignant bone tumors.

Objective To treat the patients with primary dysmenorrhea by puncturing Shiqizhui (EX-B8) and observe the change and regularity of the analgesic effect with different needle-retaining time, for providing evidence for the optimal needle-retaining time. Method Ninety eligible subjects with primary dysmenorrhea were randomized into a 20 min group of 30 cases, a 30 min group of 30 cases, and a blank control group of 30 cases. Visual Analogue Scale (VAS) was used to observe the change before and after intervention with the time, and to compare the intergroup differences. Result The acupuncture groups started to show analgesic effect 10 min after needling, and the effect increased with the needle-retaining time (P＜0.05);the therapeutic efficacy of the 30 min group was significantly superior to that of the 20 min group (P＜0.01). Conclusion Acupuncture at Shiqizhui can produce a real-time analgesic effect for patients with primary dysmenorrhea, and retaining the needle for 30 min is superior to 20 min.

Objective To explore scanning technique in 64-slice spiral CT angiography, and to evaluate the clinical value of various of post-processing methods.Methods 45 patients were examined with CT angiography, including 4 cases of thoracic aorta, 15 cases of abdominal aorta,10 cases of pulmonary artery, which delay time was determined by bolus tracking. The delay time of others ,including 4 cases of cerebrovascular, 6 cases of cervicum blood vessel and 6 cases of lower limb artery were determined by artifical. The initial images were processed with MPR, CPR, MIP ,SSD and VRT.Results According to standard valuation of imaging quality ,the good images were 37 cases, the better were 8 cases and none was bad.Conclusion As far as the diagnosis of great vessels is concerned, 64-slice spiral CTA can instead of DSA. MIP and VRT are important methods in post-processing of image.

Background Whether serum uric acid are related with ischemic stroke in essential hypertension (EH) is controversial. Objective To delineate the relationship between serum uric acid and ischemic stroke in EH. Methods A retrospective study was conducted in a cohort of 729 EH patients. Patients were classified into four groups according to serum uric acid level. The odds ratio for ischemic stroke was calculated with the lowest quartile as the reference. Results The prevalence of ischemic stroke in EH with quartile 4 of uric acid was higher than that in EH with quartile 1(37.9% vs 17.6%,P

Objective To investigate the effect of metabolic syndrome(MS) on the atrial fibrillation(AF) in patients with essential hypertension(EH).Methods A cross-sectional study was conducted in a cohort of 1810 hospitalization essential hypertension patients,which were divided into EH+non MS group(n=1155) and EH+MS group(n=655) according to MS criteria.Results Incidence of AF in EH+MS group was higher than that in EH+non MS group(14.4% vs 8.3%,P

This paper introduces a method for drawing the circuit diagram of the circuit board rapidly. The pictures of the circuit board are taken firstly and then are imported into Protel. Also an example is given to explain the details. The method can simplify the drawing of the schematic for the circuit board, and thus is worth popularizing.

AIM: To investigate the protective effect of anti-macrophage migration factor monoclonal antibody (anti-MIF MAb) on oleic-acid-induced acute lung injury (ALI) rats and its influence on the expression level of MIF and intercellular adhesion molecule-1(ICAM-1). METHODS: The rats were subjected to injection of oleic acid (oleic acid group) or saline solution (control group). One hours before administration of oleic acid, the rats were intraperitoneally injected with anti-MIF antibody (5 mg/kg) as the treatment group. After injecting oleic acid or saline for 4 hours, the PaO_2, lung permeability index (LPI), the number of macrophage and the level of soluble ICAM-1 (sICAM-1) in the bronchial alveolar lavage fluid (BALF) were measured. The expression level of MIF mRNA and ICAM-1 mRNA in the lung were detected by in situ hybridization, and the degree of macrophage infiltration and the expression of MIF were evaluated by double staining immunocytochemistry. RESULTS: The PaO_2 of the oleic acid group was far lower than those of the control and treatment group (P
