Objective:To investigate the eating disorder and mood among students of a female university in Beijing.Methods:352 female students from a same-sex college in Beijing,between the age of 17-25 years were in- vestigated by Eating Disorder Inventory(EDI)and Profile of Mood States-Short Form(POMS-SF).Their weight and height were also collected for calculating for their body mass index(BMI).Results:Female university students showed serious tendency of eating disorder.The negative attitudes to body and body satisfaction were serious among normal BMI female university students.The behaviors and attitudes to eating disorders among the students of fresh-woman and senior were significantly higher than other grades(x~2=17.94,P

Objective To evaluate the safety of dynamic anterior plate fixation for cervical distractive flexion injuries and compare its rigidity between different types of plate design. Methods Twelve sets of cadaveric calf spine were used in this test. All the specimens were made into distractive flexion injury models (C4-C5) ac- cording to Allen's method. After discectomy and grafting, they were randomized into three groups in which Orion, Codman, and Window instrumentations were used respectively. The stiffness of each construct was tested in flexion, extension, lateral bending and axial torsion conditions sequentially. Results Compared with an intact cervical spine, the range of motion (ROM) of an injured cervical spine increased whatever plate was applied. Orion in- strumentation presented stiffness the closest to that of the normal control, except for less torsional stiffness. Codman instrumentation provided stiffness close to that for normal and Orion groups only in lateral bending. Window's was the weakest mad not enough in all kinds of movement. Conclusions Static anterior fixation is the first choice for cervical injuries. Dynamic plate fixation may sacrifice stiffness to some extent, especially when a shifting kind of design is to be chosen.

OBJECTIVETo study on effects of acupuncture at a same point at physiological or pathological state on brain functional imaging.

METHODSElectroacupuncture was given at Neiguan (PC 6) of the healthy senile persons (normal group) and the patients of Alzheimer's disease (AD group), and they were scanned on a 1.5 T MRI scanner and the data of functional magnetic resonance imaging (fMRI) were analyzed by Statistical Parametric Mapping (SPM99). The functional imaging of different brain regions were obtained from both the healthy group and the AD group.

RESULTSBoth the frontal lobe and the temporal lobe were activated in varying degrees by electroacupuncture at Neiguan (PC 6) in the healthy group. However, the frontal lobe, the temporal lobe and the cingulate gyrus as well as the cerebellum were activated in varying degrees and other brain regions were not activated by electroacupuncture at Neiguan (PC 6) in the AD group.

CONCLUSIONAcupuncture at Neiguan (PC 6) can activate functions of different brain regions in the healthy group and the AD group, indicating that acupuncture at Neiguan (PC 6) has different effects on functional magnetic resonance imaging in different functional states.

Objective To learn the temporal-spatial distribution and clustering of hand-foot-mouth disease (HFMD)in Xiaoshan in 2014,and to provide reference and basis for prevention and control.Methods The HFMD data of Xiaoshan in 2014 was derived from the China Information System for Diseases Control and Prevention.The vector map was created by Map Info 10.0 on the background of 1∶65 000 zoning map ,extracted village and community geographical position information from Baidu map.At the village level,the spatial autocorrelation analysis and spatial scanning analysis were made using software ArcGIS10.2 and SaTScan9.2.Results In Xiaoshan,the epidemic curve of HFMD in 2014 showed two peaks,during April to July and during September to October.The global spatial autocorrelation Moran's I index was 0.442 7(P<0.001),and the global Getis-Ord G value was 0.003 3,(E(G)=0.002 1,Z(G)=11.82,P<0.001). Local autocorrelation analysis showed that the cluster state was high-high.Ningwei Street had the most hot spots.Five statistically significant HFMD clusters were identified by space-time scan statistics,the most likely cluster was located in Heshang Town,from January 6 to February 4 (RR=23.00,LLR=17.45,P<0.05).Conclusion In Xiaoshan,the major epidemic peak of HFMD in 2014 was from April to July.A positive spatial correlations was found,and the disease showed a distinct regional distribution feature and temporal-spatial clustering.The clusters were observed including the villages and communities of rural-urban continuum and in vicinity of industrial development zone in countryside.

Objective To evaluate the effects of the chronic Keshan disease's self-management in Liangshan Prefecture of Sichuan Province. Methods According to "The Serf Management Program of Chronic Keshan Disease in Liangshen Prefecture of Sichuan Province", 56 chronic Keshan disease patients were selected in the personalized self-manngemant evaluation under the instructions by endemic disease specialists and the rural doctors. Evaluation was based on changes of indexes such as the clinical symptoms, general health conditions, the electrocardiogram, X-ray, the heart function, etc, before treatment and 3 and 6 months following the treatment. Results Clinical signs and symptoms of the patients were significantly improved 3 and 6 months after the treatment, and the improvement was more obvious 6 months than 3 months following the treatment(P<0.05 or< 0.01). After treatment for 3 months, the patients'electrocardingram and heart function did not show obvious change (X2=0.05,039, P0.05); hut obvious improvements Eexcept X ray results(X2=0.61 ,P0.05)] were seen 6 months after treatment (X2=4.36,16.84, P<0.05 or<0.01). Altogether, among the 56 patients evaluated after treatment for 6 months, none achieved the clinical cure standard, 26 cases(46.3%) showed significant improvement, 17 cases (30.4%) were stable, 5 cases (8.9%) were aggravated,one case (1.8%) lost contact, and 6 cases (10.6%) died. Conclusion The project of the chronic Keshan disease's self-management is suitable for the present situati,on of the endemic regions and can he introduced to many places in our country.

Objective To evaluate low-weight mesh for tension-free repair of inguinal hernia in the elders. Methods 120 old patients ( age at 60 -97 years) underwent tension-free repair of inguinal hernia by using low-weight mesh. The early complications, time of up and about, hospital stay, postoperative chronic pain,foreign body feelings and hernia recurrence were analyzed. Results The operations were successful in all cases and the average time of operation was (43 ± 12 ) min. 9 cases suffered from edema of the scrotum, 5 cases suffered urine retention, 4 cases suffered from incision hematoma. The average time of outof-bed was ( 17.4 ± 1.8 ) h, the average hospital days was ( 7.4 ± 1.9) d. However, there were 1.7%(2/120) patients suffering from slight chronic pain and 9. 1% (11/120) patients complaining foreign body feelings. There was no recurrence after follow-up for 6 to 48 months. Conclusions The clinical application of low-weight mesh for tension-free repair of inguinal hernia in old age is safe and effective, with an additional advantage of low occurrence of chronic pain and foreign body feelings.

Objective To evaluate the diagnostic value of spiral CT [CT arterial portography (CTAP) and CT hepatic arteriography(CTHA)] for hepatic carcinoma. Methods The CTAP and CTHA manifestations in 21 patients with hepatocelluar carcinoma were analyzed and compared with those in three-phase enhanced CT . Results The detection rate of three-phase enhanced CT was 72.4% , CTAP and CTHA was 96.1% and 88.2% respectively. The detection rate of combination CTAP and CTHA was 98.7% . They could reveal tumors of 0.5 cm in diameter . Both CTAP and CTHA gave false-positive findings , such as perfusion defects in 22.3% of CTAP and non-pathologic enhancement in 30.2% of CTHA .Conclusion With the use of spiral CT technique , the quantity of contrast material administrated in CTAP and CTHA can be considerably reduced . And the quality of CT images significantly improved . The detection rate of CTAP and CTHA is higher than that of three-phase enhanced CT . Simultaneous use of both procedures may decrease the false-positive rate.
