Objective: To investigate the influence of Swiss ball exercises on clinical efficacy and stability of lumbar vertebra in patients with protrusion of lumber intervertebral disc. Method: Thirty patients with non-acute protrusion of lumber intervertebral disc were divided by gender and clinics orders into control and exercises group. Roland Morris questionaire(RMQ) and visual analogue seale(VAS) were selected as pain assessment. Pain, abdominal and back muscle strength were assessed respectively before treatment, 2 and 4 weeks after Swiss ball exercises. Both Swiss ball exercises and lumbar traction were used in exercises group. Lumbar traction was used in control group. Result: Compared with before treatment, RMQ and VAS scores decreased significantly after 4 weeks in control and exercises groups (P<0.05, P<0.01). Compared with control, RMQ and VAS scores in exercises group decreased significantly after 2 and 4 weeks respectively (P<0.05, P<0.01). Compared with control, abdominal and back muscle strength in exercises group increased significantly after 2 and 4 weeks respectively (P<0.05, P<0.01). Conclusion: The low back pain symptom of patients with protrusion of lumber intervertebral disc decreased significantly and abdominal and back muscle strength increased significantly by beth Swiss ball exercises and lumbar traction. The stability of lumbar vertebra of patients with protrusion of lumber intervertebral disc increased significantly.

Objective To compare the levels of murine basophils distribution in different organs and analyze the characteristics of CD4+T cells activation/differentiation regulated by basophils.Methods Firstly,the mononuclear leukocytes were isolated separately from periphery blood,liver,spleen,lung and lymph nodes and the percentages of FcεR I+CD49b+ basophils in different organs were investigated.Secondly,liver basophils were purified by immuno-microbead strategy and co-clutured with different cytokines for 24 h.Apoptosis status of basophils was detected by Annexin V straining method.Thirdly,Mice were subcutaneously implanted with a miniosmotic pump containing 5 μg IL-3.At day 7 after implantation,liver mononuclear cells were harvested and the percentages of basophils were analyzed.Finally,Th1/Th2 polarization influenced by basophils orientated cytokines was investigated when naive OT-Ⅱ CD4 T cells were stimulated with spleen dentritic cells and OVA peptides.Results The percentage of murine basophils in mononuclear leukocytes of liver was significantly higher than that of periphery blood,spleen,lung and lymph nodes under physiological condition.Both of in vitro and ex vivo experiments showed that IL-3 played an inhibitory role on apoptosis of basophils.Cytokines secreted by basophils was investigated to induce Th2 polarization and inhibit Th1 response when naive OT-Ⅱ CD4 T cells were co-cultured with spleen dentritic cells and OVA peptides.Conclusion Th2 response was enhanced and Th1 response was down-regulated by murine basophils,which implied that basophils might participate in the construction of liver specific physiological immuno-tolerant microenvironment.

Objective To analyze the effect of reconstruction for the proximal or distal femoral defect by a composite of massive frozen allograft and prosthesis replacement. Methods According to Enneking's classification, malignant bone tumors of the proximal or distal femur were widely resected in 28 cases. Reconstruction of the affected hip or knee joint after major joint removal was done by a composite of allograft and prosthesis. A conventional femoral component with a stem long enough to provide good fixation in the femoral shaft was threaded over a customized allograft. After the assembly had been reduced and checked for size and position, the allograft was cemented to the femoral component, and the composite was in turn cemented into the femoral shaft with PMMA. Results 26 patients were followed up from 6 to 78 months with an average of 41 months. 3 cases died within 18 months following operation; 4 case sustained recurrences within 8 months postoperatively, and underwent re-resection; and the others were alive without diseases. All patients had no dislocation, loosening or breakage of prosthesis. X-rays showed the time of bone healing between allograft and host femur was an average of 7.4 months (range, 5 to 11 months), and the rate of bone healing was 92% (24/26). Absorption was seen around allograft greater trochanter of femur in 9 cases and at femoral condyle in 6 cases. 13 cases with total hip composite replacement had good active extension-flexion degrees of an average of 85?( range, 71? to 124?), and 13 with total knee composite replacement had a rang of motion of 92?(range, 68? to 135?). The postoperative average ISOLS scale score of 26 cases by Enneking's system was 26.2 point (range, 22 to 28). Conclusion The clinical result demonstrated the composite of massive frozen allograft and prosthesis replacement has the advantages of both allograft and prosthesis. Its best indications are that the patients with a major femoral defect from benign or low grade malignant tumor have longer survival expectancy.

Objective To observe the effects of shenfu injection (SFI) on the awakening quality of the patients with hepatitis B cirrhosis undergoing splenectomy under general anethesia. Methods Forty patients with hepatitis B cirrhosis and hepatic insufficiency (ASA classⅡ~Ⅲ) underwent splenectomy by general anesthesia. Patients were all sent into the post-anesthesia care unit (PACU) shortly after the operation with unconscious and no spontaneously breathing. They were randomly divided into two groups: SFI treatment group (Group SFI, n =20) and normal saline controlled group (Group NSC, n = 20). SFI group were treated with SFI (1 mL/kg, i. v.) in 10 minutes, and NSC group were treated with normal saline (1 mL/kg,i.v.). The time of eyes opening, extubation of tracheal catheter and the detention time of PACU were recorded. The heart rate (HR) and the average artery presses (MAP) were monitored at 4 time points: before SFI and normal saline administration, 5 min, 15 min, and 45 min after administration. The incidence of restlessness during the patients awakening period was also recorded. Results The time of eyes opening, extubation and the detention time of PACU of SFI group show no significant difference compared with the NSC group (P > 0.05). SFI and normal saline intravenous injection did not cause significant changes on HR and MAP at the time of 5 min , 15 min and 45 min compared to the time of before administration (P > 0.05). The incidence of restlessness during the patients resuscitation period in SFI group were lower than in NSC group (P < 0.05). Conclusion Shenfu injection can effectively improve the awakening quality and decrease the incidence of restlessness of the patients with hepatitis B cirrhosis undergoing splenectomy under general anesthesia during the awakening period in PACU.

AIM: To observe the growthinhibiting cell cycle-modifying and apoptosis-inducing effects of satraplatin on human ovarian carcinoma cell line A2780, and to explore its possible mechanism. METHODS: The effect of satraplatin on A2780 cells proliferation was determined using MTT, and the change in cell cycle was analyzed using PI staining. Morphologic change was visualized by fluorescence and electron microscopy. AnnexinV-FITC/PI staining multiparameter flow cytometry and immuno- histochemical TUNEL assay were used to detect apoptotic cells. The activity of caspase-3 and the effect of pan-caspase inhibitor on cell viability were measured as well. RESULTS: The growthinhibiting and apoptosis-inducing effects of satraplatin were dose-dependent and similar to those of cisplatin. Satraplatin mainly caused A2780 cell accumulation in S phase accompanied by minor accumulation in G2/M phase. Cells treated with satraplatin exhibited typical morphology of apoptosis. Satraplatin-induced increase in caspase-3 activity of A2780 cells was concentration-dependent. The viability of A2780 cells was affected by pan-caspase inhibitor z-VAD-fmk in a dose-dependent manner under certain concentration of z-VAD-fmk. CONCLUSION: Satraplatin-induced apoptosis in A2780 in vitro was observed. Caspase-dependent and independent pathways were involved in apoptosis induced by satraplatin, and the latter included caspase-3 dependent and non-caspase-3 dependent pathways.
