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.

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.

Many clinical researches and animal experiments proved that kineditherapy could undoubtedly improve the blood lipid level of dyslipidemia. The mechanism is that kineditherapy can regulate lipid metabolism, lipoprotein and lipoproteinic lipase. On the other hands kinesitherapy also indirectly modulates insulin, adhesion factors and cytokines to influence the blood lipid level. It is important for patients to choose suitable exercises and insist them for a long time. The effect of different activity intensity on lipid level has no distinct difference.

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.

Objective To investigate the nutrition support during stress response period after tumor ex-tirpation in middle-aged and elderly patients with oral and maxillofacial tumors. Methods Sixty patients who had undergone maxillofacial tumor extirpation were randomly divided into nutrition therapy group (n = 35) and control group ( n = 25 ). Patients in nutrition therapy group received enteral nutritional treatment, while patients in control group fed themselves. The nutritional status of the two groups before operations were evaluated with Concise Nutritional Assessment Indicators of human body measurement and biochemistry were used to evaluate the nutritional conditions. The incidence of post-operational complications and recovery time ( from the operation to discharge) were analyzed. Results The weight and arm muscle circumference in the nutrition therapy group significantly decreased after operations (P <0. 05). However, in the control group, all the nutritional indica-tors except the total lymphocyte count were significantly lower than the baseline levels after operations (P < 0. 05 ) ; particularly, of the average body weight decreased by about 6 kg. The incidence of complications in the nutrition therapy group was significantly lower than that in control group (5. 7% vs. 12. 0% , P <0. 05). The recovery time was significantly longer in the control group than that in the nutrition therapy group [ (28. 62± 2.38) vs. (22. 76± 3. 24) d, P < 0. 01 ]. Conclusion The nutritional support during the stress response period can satisfy the demands of high catabolism after maxillofacial tumor extirpation operation in middle-aged and elderly patients.
