RESUMO
Objective To evaluate the reliability and validity of the Chinese version of multidimen-sional existential meaning scale (MEMS-C) in college students. Methods The MEMS was translated into Chinese. A total of 453 college students was tested by convenience sampling method via online survery. Eighteen college students were surveyed by MEMS-C before and after a two-week interval in order to analyze the retest reliability of the scale. Results The fitting indexes of the confirmatory factor analysis were χ2=450. 510,df=74,P<0. 01,χ2/df=6. 088,GFI=0. 859,CFI=0. 930,RMSEA=0. 106,RMR=0. 074,SRMR=0. 0494. The correlation validity coefficient of the scale was 0. 617 (P<0. 01). Internal consistency relia-bility coefficient of the total scale,comprehension,purpose,and mattering factors were 0. 935,0. 893,0. 936, 0. 733. The retest reliability was 0. 908 (P<0. 01). Conclusion The MEMS-C has good reliability and va-lidity. It is suitable to measure the sense of life of college students.
RESUMO
BACKGROUND: In recent years, percutaneous kyphoplasty (PKP) has been widely used in the treatment of osteoporotic vertebral compression fractures, but there are still some complications, such as bone cement leakage and re-fractures, and a lack of follow-up treatment.OBJECTIVE: To investigate the effect of PKP with low-dose bone cement in combination with zoledronic acid on bone mineral density (BMD), vertebral height and low back pain after osteoporotic vertebral compression fractures.METHODS: Eighty patients with osteoporotic vertebral compression fractures were equally randomized into test group (treated with PKP with low-dose bone cement in combination with zoledronic acid) and control group (treated with PKP with conventional bone cement). Visual analog scale score, vertebral height, and Cobb angle were detected before, at 3 days after treatment and at the final follow-up visit. BMD and re-fracture incidence were reviewed 1 year after treatment.RESULTS AND CONCLUSION: Visual analog scale scores, vertebral height, and Cobb angle were significantly improved in both groups at 3 days after treatment and at the final follow-up visit (P < 0.05); however, there was no statistical difference between the test and control groups. One year after treatment, the BMD value was significantly increased in the test group (P < 0.05), but showed no change in the control group as compared with the pretreatment.Postoperatively adjacent vertebral fractures were found in one case of the test group, and five cases in five cases of the control group. These findings indicate that PKP with low-dose bone cement in combination of zoledronic acid can effectively relieve pain symptoms, restore the height of the vertebral body, significantly increase BMD value and reduce the incidence of adjacent vertebral fractures in patients with osteoporotic vertebral compression fractures.
RESUMO
Objective To compare medium-term therapeutic effect by bilateral and unilateral puncture plasma coblation nucleoplasty(PCN) in the lumbar disc herniation patients. Methods 90 cases confirmed no significant rupture of annulus fibrosus of lumbar disc herniation by CT or MRI were randomly divided into two groups. Bilateral and unilateral puncture plasma coblation nucleoplasty groups were respectively divided into group A and group B, and compared the JOA scores. Results 82 patients were followed up for 10 ～ 32 months,the average follow-up time was 16.2 months. Preoperative JOA scores of the two groups were not statistically significant(P ＞ 0.05) but the postoperative follow-up JOA scores were higher than preoperative(P ＜0.05) and the JOA scores of group A were higher than group B(P ＜0.05). Conclusion The medium-term therapeutic efficacy of bilateral puncture coblation nucleoplasty was superior to unilateral therpy.
RESUMO
Objective To discuss the protective effects and mechanisms of dexamethasone and Shenfu sepa-rate and joint administration of flap after ischemia-reperfusion injury. Methods 40-month-old fairly healthy rats were randomly divided into 4 group as A, B, C, D, and to product the abdominal island flap, then blocking the flow of blood of the pedicle artery respectively before 30 minutes when injecting with normal saline (1 ml/kg), dexametha-sone (1 ml/kg), Senate (10 ml/kg), joint injection with dexamethasone (1 ml/kg) and Shenfu (10 ml/kg). 4 groups of animals' blood samples were collected from the pedicle vein before the time of I hour when blocking vascu-lar pedicle and reperfusion after the time of 1 h, 6 h, 12 h, 24 h, respectively. Then the plasma concentration of TNF-α was measured. Results The concentration of TNF-α in the treatment group was significantly lower than the blank group(P <0.01). And the group D and the group B、C has significant differences either(P <0.01). Conclu-sion Using Dexamethasone, Shenfu injection in early can reduce the concentration of TNFα in repeffusion injury of flap and has a protective effect on the flap, but make better effect in combined.
RESUMO
Objective To evaluate the efficacy of Grosse Kempf interlocking intramedullary nailing (Grosse Kempf IIN) and AO plate in the treatment of tibial fractures. Methods A retrospective analysis was done on the recovery of 55 cases with tibial fractures treated with the Grosse Kempf IIN (Group A) and 40 treated with AO plate (Group B) from 1994. Results The 10 26 months follow up showed that the healing rate and the infection rate were 98.2% (54/55) and 1.8% (1/55) respectively in the Group A with a mean healing time for 5.6 months and 90.0% (36/40) and 12.5% (5/40) respectively in the Group B with a mean healing time for 7.5 months. Conclusions The Grosse Kempf IIN has obvious advantage of excellent biodynamics, reliable fixation, simple operation, less trauma on regional blood supply and is more effective in the treatment of tibial fractures than the AO plate. Nevertheless, I IN itself has limitation for further application.

No significant differences between the two groups were found in terms of associated injury, ISS, ICU length of hospital stay,complication or mortality, while significant difference existed between two groups in terms of associated shock (?2=6.078,P
