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 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.

Objective To study the effect and the possible mechanism of delavirdine on muhidrng resist-ance-aasociated protein 2(MRAP2)-mediated multidrug resistance in LLC/cMOAT cells. Methods MTT assay was used to determine the effects of delavirdine on proliferation of LLC/CMV and LLC/cMOAT cells. The inhibitory effects of vincristine (VCR),cisplatin (DDP),adriamycin (ADM) and etoposide (VP-16) used alone or in combi-nation with delavirdine on the proliferation of LLC/CMV and LLC/cMOAT cells were evaluated by MTT assay. The cell cycle distribution, the apoptosis rate of the cells treated with different concentration of delavirdine and the intra-cellular concentration of ADM were determined by flow cytometry (FCM). Results Delavirdine at the concentration of 4 μmol/L and below showed no significant cytotoxicity to LLC/CMV and LLC/cMOAT cells. The resistance of LLC/cMOAT cells to VCB, VP-16, ADM and DDP were 9.58,1.11,2.98 and 3.96 folds of that of LLC/CMV cells. When 2 μmol/L delavirdine was added, the resistance was 5.21 and 2.55 folds respectively;when 4 μmol/L dela-virdine was edded,the resistance was 7.56 and 3.03 ,while 2,4 μmol/L delavirdine made no significant changes to the chemosensitivity of LLC/CMV cells to VCR and DDP(P>0.05). Cellular cycle analysis demonstrated that 0,6, 12,24 hours after co-cultured with delavirdine the amount of cells at G1 phase increased from(38.92±0.15)% to (56.87±2.23)%,(65.36±2.76)% and (74.77±5.06)%. The cell apoptosis rate increased from 1.77% to 17.45% and 28.52% when treated with delavirdine at 2,4 μmol/L and VCR for 24 h. When treated with 2,4 μmol/L delavirdine, ADM accumulation in LLC/cMOAT cells was enhanced significantly(P<0.05). Conclusion DLV can partially reverse the multidrng resistance of LLC/cMOAT cells, and the reverse effect correlates to the concentration. The possible mechanism may involve the growth arrest at G1, increasing of intracellular drug concen-tration and promoting apoptosis.
