ABSTRACT
OBJECTIVE: To provide reference basis for standardizing the medicinal market of Wudu area of Gansu.METHODS: Through market research and sample collecting of Sapashnikovia divicata in Wudu of Gansu as well as a comparatively study on the morphological characters,histological structure and physicalchemical properties of Sapashnikovia divicata,a statistical analysis was conducted on certified Sapashnikovia divicata and its faked product circulating in Wudu of Gansu.RESULTS: There were a lot of faked Sapashnikovia divicata product which were very similar in exterior shape and property to the certified products,but much more different in microscopical feature and physicalchemical properties from the certified products.CONCLUSION: The study provides the theoretical basis for standardizing the market of Sapashnikovia divicata.
ABSTRACT
Objective To promote more understanding of bone metastasis and reduce the misdiag-nostic rate of bone metastatic tumor.Methods The mechanism of skeletal metastasis,the spreading pathway of tumor to bone,its frequency and distribution of skeletal metastasis,as well as relative frequency of primary malignant tumor,clinical features,diagnosis and differential diagnosis with bone metastastic tumor were re-viewed.Five misdiagnosed cases as bone metastasis were presented.Results Five cases of patients were ob-tained post-longer time of follow-up examination,ranging from24to96months(average57.6months).Case1was carcinoma of lung,and case2carcinoma of prostatic gland,both were living and well.Case4and case5were tuberculosis of lumbar spine,their conditions were stable and satisfied.A lesion of lum-bo sacral disc in case3was found and diagnosed as infection and kept stable without any back and extremities pain since first attack of disease.The causes of misdiagnosis were analyzed.Conclusion Meticulous review of the history and clinical features as well as proper explanation of the supplemental data from plain X-ray,bone scintigraphy,CT and MRI findings are essential for diagnosis of majority of bone metastatic tumor.Al -though such new imaging devices(as bone scintigraphy,CT and MRI )possess a high sensitivity for early detection of bone metastasis,yet with a poor specificity,hence orthopaedic surgeon have to catch hold of proper understanding about new imaging techniques.In difficult and doubtful cases,the bone biopsy under CT guiding may be needed,the radioisotopic Hawkeye system and diffusion weighted MR imaging are rec-ommended for differential diagnosis of senile acute benign(e.g.osteoporosis)and malignant (e.g.metastasis)vertebral body com pressive fracture.
ABSTRACT
Objective To investigate the incidence and the factors related to male senile osteoporosiswith dual energy X - ray ahsorptiometry (DEXA). Methods 139 cases of healthy elderly men were examined by WHO T - Score with DEXA to estimate the incidence of male senile osteoporosis. The relationshipbetween osteoporosis and various parameters such as age, body weight, smoking etc. was assessed. The resultsof DEXA examination were compared with those of plain X - ray film of lateral view of lumbar spine, hip Singhindex etc. Bone turnover markers were examined to study their relationship with osteoporosis by DEXA. Results The incidence of male senile osteoporosis was 26. 6%. Body weight and smoking were closely relatedto osteoporosis. No signifieant relationship was found between bone turnover markers and osteoporosis. PlainX - ray film of lumbar spine and hip Singh index bore a relationship with osteoporosis by DEXA. ConclusionIncidence of male senile osteoporosis is rather high, and it is imper'tant to pay more attention to the preventionand treatment of male senile osteoporosis. DEXA equipment is not popular in general hospital, therefore theplain X - ray film of lumbar spine and hip Singh index were found to have some value for the diagnosis of senileosteoporosis.
