Objective 99Tcm-4,9-diaza-3,3,10,10-tetramethyldodecan-2,11-dione dioxime(HL91),a new type of hypoxic agents,accumulates in tumor hypoxic tissue specifically.The aim of this study was to evaluate the value of 99Tcm-HL91 imaging in the diagnosis of bone metastasis.Methods Nineteen cases with bone metastasis(without any treatment)and 8 cases with benign lesions underwent SPECT imaging at 4 h after injection of 740 MBq of 99Tcm-HL91 along with 99Tcm-methylene diphosphonic acid(MDP)imaging.Regions of interest(ROIs)were drawn in tumor tissue and contralateral normal tissue respectively,and the radioactivity ratios of tumor-to-normal(T/N)were calculated.The t-test was used for data analysis with SPSS 11.0.Results There were visible uptake of 99Tcm-HL91 in 79 out of 85 focuses in 19 patients of bone metastasis;however,there was no obvious uptake of 99Tcm-HL91 in 12 focuses of 8 patients of benign lesions.Significant difference existed between the T/N values of malignant(1.877±0.288)and benign lesions[(0.735±0.236);t=13.065,P＜0.05].However,the T/N value of bone metastasis from lung cancer did not differ with that from prostate cancer(1.915±0.344 and 1.825±0.175,respectively;t=1.378,P＞0.05).Conclusion The results indicated that 99Tcm-HL91 was useful in diagnosing the malignant and benign bone lesions.

Objective To observe the effect of auricular-plaster therapy on non-incisional pain from post-laparoscopic surgery.Methods Sixty patients with non-incisional pains from laparoscopic surgery were divided into experimental group (n=30) and control group (n=30).The patients of control group after laparoscopic surgery were routinely given the oxygen inhalation for 6 hours and encouraged to do off-bed activity earlier.Besides the above-mentioned treatment,the patients of experimental group were additionally given auricular-plaster therapy.The patients of two groups were compared in terms of pain intensity and duration.Result The pain duration in the experimental group was significantly shorter and the pain density was significantly lower than that of the control group (bothP<0.05).Conclusion Auricular-plaster therapy can significantly reduce the duration and intensity of non-incisional pain from gynecological laparoscopy.

Objective To explore ways to decrease peripheral vascular complications during parenteral nutrition through peripheral veins. Methods According to the support sequences of giving peripheral parenteral nutrition, ninty perioperative cases were randomly divided into low(20. 3 kPa·h-1 ),medium(27. 1 kPa·h-1 ) and high(33. 9 kPa·h-1 ) osmotic pressure rates(n=30 in each group). The infusion pump was used to control the rate of infusion. The total parenteral nutrient was infused through BD24G venous indwelling needles. The pain ratings at injection sites were evaluated after parenteral nutrition everyday,the incidences of phlebitis were observed three days later after removing the indwelling needles. ResultsUnder the low osmotic pressure,the pain was mild,while for the medium osmotic pressure,the pain became more obvious. The pain was aggravated obviously under high osmotic pressure. There were only two cases of over grade-II phlebitis under low osmotic pressure rate,9 cases under medium osmotic pressure rate and 14 cases under high osmotic pressure rate, in which a grade-Ⅲ phlebitis developed. Conclusion Decreasing the osmotic pressure rate through peripheral venous is an effective method to avoid or reduce the incidences of peripheral vascular complications with the peripheral parenteral nutrition support.

Objective To explore the impact of total parathyroidectomy(tPTX)on carotid-femoral pulse wave velocity(cfPWV)in hemodialysis patients. Methods A total of 35 patients undergoing hemodialysis with refractory secondary hyperparathyroidism and treated with tPTX were studied. Before tPTX and 1 year after the oper-ation,cfPWVwas measured and hepatic and renal function,serum calcium,serum phosphorus,intact parathyroid hormone and hemoglobin were measured. The impact of tPTX on cfPWV in hemodialysis patients was analyzed. Results Serum calcium,serum phosphorus and intact parathyroid hormone decreased(P < 0.01),while hemo-globin and serum albumin increased(P < 0.01)and cfPWV decreased 1 year after the operation,which showed statistical significance(P<0.01). The cfPWV of the patients with tPTX was still higher than that of healthy indi-viduals(P<0.01). Conclusion tPTX can effectively reduce cfPWV in hemodialysis patients with refractory sec-ondary hyperparathyroidism.

Objective To evaluate the value of reconstruction of three-dimentional CT in development dislocation of hip(DDH)in children.Methods Twelve cases of DDH concluded 4 bilateral and 8 unilateral cases.To sum up,16 sick hips were operated and 8 normal hips were also obtained by three-dimensional CT(Hip speed Fi/x,GE Co).Results 3D reconstruction were used to show femoral head,(acetabulum) and relationship of acetabulum and femoral head respectively.The difference between FNA measurement of sick hips and those of normal hips were significant(P
