ABSTRACT
Objective To describe the epidemiological characteristics of cervical spine fracture combined with trauma cervical spinal cord injury (TCSCI) in Guangxi province. Methods A total of 385 patients met the inclusion criteria were enrolled for retrospective investigation. Detailed information included age, sex, marital status, occupation, date of admission, mechanisms of trauma, level of injury, ASIA grade, concomitant injuries, length of hospital stay, complications, and mortality. Results The ratio of Male/Female was 4.4:1. The average age of the patients was 47.9 years, and 88.8％ of the patients were married. 72.9％ of TCSCI occurred between the age of 35-64 years. Farmers accounted for the largest number of patients with TCSCIs, and 63％ of patients with TCSCI were caused by falling. The damage was located at the C3-C5 level, accounting for 63.8％. More than half of the patients with CSCI had brain injury. The most common complication was respiratory infection (54.5％). Among the injury levels, the proportions of ASIA grade A, B, C, and D were 34.8％, 8.5％, 35.5％, and 21％, respectively. During the treatment, 58 patients required cardiopulmonary resuscitation, and 36 patients required mechanical ventilation. The average length of hospital stay was (26.5±21.6) d. Of the 375 patients discharged from the hospital, 51.2％ patients had no improvement in the muscle strength. Conclusions Falling is the main cause of CSCI and men are more likely to be exposed to the injury. Patients with TCSCI have long treatment time and poor treatment results. Additionally, complications during the treatment should not be ignored.
ABSTRACT
Objective To explore the improvement of cognitive impairment in patients with mild and moderate vascular cognitive impairment( VCI) treated with cerebralcare granule ( CG) and basic treat-ment.Methods From October in 2014 to December in 2016 year,143 cases of VCI patients were admitted from six hospitals in some areas of Hebei Province as the research objects,and divided into CG treatment group (experimental group,n=98) and conventional treatment group (control group,n=66).Three months and six months after treatment,the score of mental state examination ( MMSE) ,the Montreal cognitive assess-ment scale ( MoCA) and the daily living capacity scale( ADL) of the two groups were compared after 3 and 6 moths of treatment.Results ①The total score of MMSE in the experimental group was higher than that of the control group for six months after treatment, and the difference was statistically significant ( ( 23. 76 ± 4.02) vs (21.52±5.13),P<0.05).②Six months after treatment,the total score of MoCA ((21.06±4.66) vs (18.32±5.20)) and visual spatial/executive function((3.05±1.37) vs (2.42±1.66)),calculation force ((2.24±0.84) vs (1.83±1.05)) and orientation ability((5.20±1.12) vs (4.06±1.35)) scores in the ex-perimental group were significantly higher than those in the control group (P<0.05) .③Six months after treat-ment,the ADL score in the experimental group was lower than that before treatment,and the difference was statistically significant((24.96±8.74) vs (29.20±11.55),P<0.05);while there was no significant difference in the ADL score between the experimental group and the control group after 6 months (P>0.05).Conclusion CG can improve cognitive function in mild to moderate VCI patients,mainly in visual space/execution func-tion,calculation ability and orientation ability,and with the extension of treatment time,the curative effect is more obvious.
ABSTRACT
ObjectiveTo investigate the value of combined digital mammography and Color Doppler Mammasonography in the diagnosis of the breast carcinoma with ROC analysis.MethodsFifty female patients with breast carcinoma and fifty female patients with breast benign lesions confirmed by means of surgery and histopathological examinations were studied.All patients were examined by Digital Mammagraphy and Color Doppler Mammasonography.Images of all patients were sorted and divided into three groups,Digital radiographs of all patients was the first group,and the second group was Color Doppler photographs,and the third was included the above two photographs.Each group was evaluated respectively by three radiologists independently.The diagnostic result of breast carcinoma or benign lesions were investigated with a five point confidence-rating scale:(1)definitely positive;(2)probably positive;(3)indeterminate;(4)probably negative,and(5)definitely negative.ROC analysis was made with SPSS 11.0 software.The differences of the area under the curve for each group was made by Z test.ResultsThe average number of breast carcinoma diagnosed by three radiologists with digital mammography,Color Doppler Mammasonogaraphy and both of them was 42,38,and 48,respectively;and the average number of breast benign lesions was 40,43,and 47,respectively.The sensitivity and specificity for digital mammography was 84%(42/50),80%(40/50),and they were 76%(38/50),86%(43/50)for Color Doppler;and 96%(48/50),94%(47/50)for two modes combination.ROC analysis indicated that the average area under the curve was 0.852 for Digital Mammagraphy,0.825 for Color Doppler,and 0.952 for both combined.For digital mammography combined with Color Doppler Mammasono-garaphy on diagnosis breast carcinoma,the area under the curve(Az)was significally larger than that for digital mammography(Z1=2.183,P＜0.01),and also larger than that for Color Doppler Mammasono-garaphy(Z2=2.581,P＜0.01), respectively.Conclusions Among three medical imaging modes on diagnosing breast carcinoma,the diagnostic value of digital mammography combined with Color Doppler Mammasono-garaphy was the highest. It was helpful on detecting and diagnosing breast carcinoma early.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the set-up and preliminary performance of a digital radiology conference system and its characteristics.</p><p><b>METHODS</b>The imaging system included a dual-screen image-text workstation with a Matrox G450 demonstration dual-head card, two multimedia projectors, a large screen, and a line-pair and grey scale test card. Patient information on radiology information system (RIS) and images on picture archiving and communication system (PACS) were fetched with GE Radworks software based on Intranet and PACS. The fetching velocity and resolution and grey scale of the images were measured.</p><p><b>RESULTS</b>Patient information in the form of texts and images were demonstrated successfully on two screens with Matrox G450 demonstration dual-head card and switched rapidly between text-image two-screen and image two-screen. The image fetching velocity was fast, the resolution was high, and the grey scale was good.</p><p><b>CONCLUSION</b>The digital conference radiology system is good, and should be popularized.</p>
