Strontium-89(89Sr)therapy has been recognized as an effective method for treating bone metastases. It functions as a calcium analog that binds with collagen matrix produced by the MC3T3-E1 cells during collagen mineralization. 89Sr emits pure β rays which palliate bone pains and reduce the number of new metastasis sites. Response to 89Sr is affected by factors such as the location, size and histological type of lung cancer, the type of metastasis and the duration of treatment, and can be predicted by relief of bone pain, elimination of metastasis, CD4 +/CD8 +, ALP, and others. 89Sr therapy is safe and effective. Repeat administration or combined used with other treatments can improve the therapeutic effect of 89Sr.

Objective :To establish a simple, reproducible brain edema model induced by endotoxin in infant rats and explore the role of intracellular free calcium and calmodulin (CaM). in the development of brain edema. Methods: A total of 45 infant rats were divided randomly into endotoxin treated( n = 36) and control( n = 9) group. The animals were intraperitoneally injected with 10mg/kg of endotoxin or saline respectively. The brain tissue intracelluar free [Ca2 + ] as well as the expression of CaM was detected by fluorescence and protein hybridizaton methods respectively. The tissue water content,Evans Blue content and pathology under electronic microscope were also observed. Results:Brain water and EB content were remarkably increased in endotoxin treated animals compared with those in the control, in which the intracellular free [Ca2+ ] was also significantly increased and the expression of CaM up - regulated. Electron microscopic studies revealed that the blood - brain barrier(BBB)was disrupted with neuronal degeneration,neurogliocyte swelling and necrosis. Conculsion :These results suggest that LPS increases the intracellular free [Ca2+ ] ,and activates the CaM - dependent function via Ca2+ /CaM pathway,which might relate to the increased BBB permeability and brain edema formation.

Objective To compare the clinical effects of low-temperature plasma ablation combined with adenoidectomy and decolle-ment in the treatment for patients with sleep apnea syndrome.Methods Totally 68 patients with sleep apnea syndrome who underwent elec-tive surgical treatment in our hospital from June 2013 to February 2015 were selected as the study objects.According to the order of treat-ment,the patients were randomly divided into the control group and the observation group,with 34 cases in each group.The control group were treated by routine decollement.The observation group were treated by low-temperature plasma ablation combined with adenoidectomy.After operation,the 2 groups were followed up for 6 months.The improvement effects of different operative methods in clinical symptoms and prog-nosis of patients with sleep apnea syndrome were compared.Results The total effective rate in the observation group (97.06%)was higher than that in the control group (82.35%),and the difference was statistically significant (P <0.05).The postoperative VAS pain grading of the observation group was relatively lower.The normal proportion (50.00%) was significantly higher than that in the control group (11.76%).Patients with moderate and severe pain in the control group accounted for 44.12% and 14.71% respectively,which were signif-icantly higher than those in the observation group(P <0.05).The incidence of postoperative bleeding in the observation group(2.94%)was significantly lower than that in the control group while the incidence of fever was higher than that in the control group (P <0.05).After oper-ation and at the end of the follow-up,OSA-18 score of the observation group decreased significantly and were (46.66 ±7.87)and (33.47 ± 10.59)respectively.The decreased range was greater than those in the control group (P <0.05).Conclusion To adopt low-temperature plasma radiofrequency ablation combined with adenoidectomy in the treatment of patients with sleep apnea syndrome can improve the surgical treatment effect,reduce postoperative pain,reduce the incidence of postoperative bleeding,optimize patients’quality of life and improve the prognosis.

Objective To evaluate the effects of inhaled nitric oxide (iNO) therapy combined with conventional ventilation in the infants with persistent pulmonary hypertension of the newborn (PPHN).Methods NO inspiration was added for 22 infants with PPI-IN ventilated with FiO2≥0. 9,PIP≥30 cm H2O,PEEP≥3 cm H2O,RR≥50 bpm for 4～6 hours,with SpO2 still < 90% and PaO2 <55 mm Hg. The iNO concentration started at (10～20)×10-6 for 20 infants,and (20～40)×10-6 for 2 infants. The iNO would be stopped when the concentration reached 40×10 -6 without any sign of improvement. The SpO2 ,blood gas analyses,blood pressure, heart rate and NO: concentration were moraitored during therapy and the resulting data compared to readings before administration of int. Results Clinical situation were significantly improved in 20 (91%) of the infants with SpO2 gradually going up after 10 minutes of int. Before iNO,mean Fit2 was 0. 9±0. 1 ,SpO2 was(76. 3±13.3)% ,and Pat2 was (46. 4±10. 1 ) man Hg. From 1 to 6 hours after iNO,SpO2 increased to(95. 1±3.8)% ,Pat2 increased to(92. 8±24.7) mm Hg,FiO2 decreased to 0.6 s0. 1.The differences were significant (P < 0. 01 ). Eighteen of 22 (82%) infants surviving. Conclusion iNO is effective in alleviating PPHN in infants. There are no remarkable side effects. It is more beneficial to start the iNO concentration at (10～20)×10-6 while some infants may need NO concentration at up to (20～40)×10-6.
