BACKGROUND: The bone fragments from spinal vertebral fracture can enter into vertebral canal to cause neural functional injury. The restoration of neural function after injury is mainly determined by the character and extent of primary injury, and is related with the spinal injured range. Early imageological analysis can evaluate the degree and range of spinal injury to preliminarily evaluate the therapeutic method and prognosis of the patient.OBJECTIVE: To explore the merit of MRI in the evaluation of function prognosis in compressive fracture induced by spinal trauma or primary osteoporosis to provide a gist for early rehabilitative intervention.DESIGN: A case retrospective study by employing patients with benign vertebral compressive fracture as subjects.SETTING: Department of Imageology of Henan Provincial Hebi Mineral Bureau General Hospital, Department of Radiology of affiliated hospitals of two universities.PARTICIPANTS: Totally 107 cases(123 vertebras) of benign vertebral compressive fracture with complete clinical data including 65 cases of trauma (trauma group, 71 vertebras) and 42 cases of osteoporosis(osteoporosis group, 52 vertebras) were selected from 125 spinal MRI testees of the first affiliated hospital of Beijing Medical University and the first affiliated hospital of Xinxiang Medical College for retrospective analysis.INTERVENTIONS: MRI images of the compressive vertebras in 107 cases (123 vertebras) induced by acute trauma or primary osteoporosis were comparatively analyzed by two vice botanic physicians with blindness method.Vertebral compression was classified into "wedge-shaped" or "flat-shaped" based on the difference between anterior and posterior height of the deformed vertebras and the shapes to observe whether there was bone fragment or not and typical fracture line.RESULTS: MRI manifestation of osteoporosis compression: medullary signal was completely kept in the deformed vertebras with the mixture of high signals. The anterior superior angle of vertebra stuck into vertebral canal. Strip low signal was under the endplate of T1 vertebra. The anterior and posterior vertebral border had normal morphology or slightly sucked with smooth margin. Vertebral vein was clearly displayed. MRI manifestation of traumatic compression: vertebra had relatively even low signal and kept partial medullary signals. Vertebra was obviously deformed with para-vertebral hematoma. There was fracture line or usually accompanied with medullary edema, and cystic degeneration. Vertebral enhancement was an important manifestation of fracture rehabilitative stage, which was the indicator for the judgment of fresh or old fracture.CONCLUSION: MRI can differentiate spinal traumatic fracture and primary osteoporosis fracture, judge fracture time, and preliminarily evaluate the function and prognosis of the patient.

Objective To investigate the prevalence of vitiligo in China through a multi-center and larse-population epidemiological survey.Methods A community-based survey was conducted in 6 cities from 6 provinces.Cluster sampling method was used.Subjects were required to fulfill the self-report questionnaires and received physical examination by dermatologists.EpiData and SPSS11.5 were utilized for statistical analysis. Results Totally,19 974 patients participated in this study,and 17 345 valid questionnaires were retrieved with a return rate of 86.84%.Of them,122 were found to have vitiligo.The prevalence and standardized prevalence of vitiligo was 0.70% and 0.56% in all patients,0.95% (75) and 0.69% in male patients and 0.50% (47) and O.45% in female patients.respectively.A significant elevation was observed in the prevalence of vitiligo in males than in females (P<0.01).The prevalence of vitiligo was increased with age and peaked in patients aging from 60 to 69 years and those over 70 years.The age at onset of vitiligo varied from 0 to 19 years in 21.85% of these patients,from 20 to 49 years in 47.05%.The most connnon type was focal vitiligo,which accounted for 36.06%,while the rarest type wag segmental type (2.46%).The pesitivity rate of family history of vitiligo was 9.84% in patients and 1.31% in community population (P<0.01).About 31.97% of the patients complained of negative influence of vitiligo on quality of life.Conclusions The standardized prevalence of vitiligo is 0.56%in 6 provinces from China.Males seem to have a higher prevalence of vifiligo than females.

Objective: Investigated the status quo of quality control of cancer chemotherapy in hospitals in Beijing to discover the main problems and provide the improvement measures. Methods: One medical record of cancer chemotherapy was taken every month for examination of quality control, and a total of 10 medical records in each hospital were examined. A total of 756 medical records from 76 hospitals were examined. Results: The results of analysis showed that the overall standardization and quality control of cancer chemotherapy was positively correlated with the grade of hospital. Only 36.8% of the hospitals were equipped with Pharmacy Intravenous Admixture Services (PIVAS). In terms of quality control of chemotherapy and medicine, the department of oncology had better performance than other departments (P<0.01). The scores of quality control of chemotherapy and medicine in the hospitals with clinical specialist pharmacists were 50.6 and 14.5, significantly higher than 47.2 and 12.7 of those without clinical specialist pharmacists (P<0.05). Conclusion We should focus on the quality control of cancer chemotherapy in secondary hospitals, reinforce the training of oncology specialists, establish the admission system of oncologists, enhance the training of oncology clinical pharmacists and promote the standardization of cancer chemotherapy.
