OBJECTIVETo evaluate the clinical effects of percutaneous pedicle screw fixation(PPSF) combined with percutaneous vertebroplasty(PVP) for the treatment of osteoporotic thoracolumbar fractures.

METHODSThe clinical data of 94 patients with osteoporotic thoracolumbar fractures treated from January 2014 to December 2015 were retrospectively analyzed. There were 31 males and 63 females, aged from 65 to 70 years old with an average of 67.2 years. Fracture level was T₁₁ on 15 cases, T₁₂ on 32 cases, L₁ on 29 cases and L₂ on 18 cases. The patients were divided into two groups according to different therapeutic methods. Percutaneous pedicle screw fixation combined with percutaneous vertebroplasty were applied in 43 patients(group A) and percutaneous vertebroplasty was applied to 51 patients(group B). Operation time, intraoperative blood loss, bone cement volume, postoperative in-bed time were recorded; preoperatively, 3 d, 1 year after the operation, the ratios of anterior border heights, sagittal Cobb angles, visual analogue scale(VAS) scores were compared between two groups. The condition of postoperative complication in two groups was analyzed.

RESULTSAll the patients were followed up for 12 to 24 months with an average of 18.5 months. Operation time of group A [(96.2±28.7) min] was longer than that of group B [(31.8±10.6) min]. Intraoperative blood loss of group A[(62.2±25.5) ml] was more than that of group B [(25.4±10.9) ml]. Bone cement volume of group A [(5.5±0.5) ml] was larger than that of group B [(4.9±1.1) ml]. Postoperative in-bed time of group A[(5.1±1.8) d] was longer than that of group B[(1.8±0.7) d]. There were significant differences in operation time, intraoperative blood loss, bone cement volume, postoperative in-bed time between two groups(<0.05). Three days, 12 months after the operation, the ratios of anterior border heights and Cobb angles in two groups were significantly improved. At final follow-up, the ratio of anterior border height and Cobb angle of group A[(85.6±3.5)%, (11.9±5.3)°] were better than of group B[(84.2±4.5)%, (15.3±3.4)°](<0.05). Three cases in group B had re-collapse of cemented vertebral bodies. Postoperative at 3 d, 1 year, VAS score of all patients had significantly decreased(<0.05), and there was no significant difference between two groups(>0.05).

CONCLUSIONSCompared to simple PVP, PPSF combined with PVP in treating osteoporotic thoracolumbar fracture can obtain stronger vertebral strength and stiffness, furthermore to improve vertebral reduced effect, keeping vertebral heights, and preventing vertebral re-collapse.

To explore the optimized dispatch of the rescue resources based on the mastered resources informa-tion. The objective function was set as the shortest rescue time, and 0-1 programming models were established and solved for the conditions that the number of medical rescue units was more or less than needed by the missions. In the two conditions, the model's calculated results were both optimal, and could be used to obtain the optimal dispatch solutions while the medical rescue time was the shortest. The 0-1 programming model can be effectively used to optimize dispatch strategy for medical rescue team.

Objective To analyze the correlation of traditional Chinese medical constitution types withcardiovascular risk factors in community hypertension patients. Methods We defined the constitution types of 1108 community hypertension patients, created personal health archives and provided routine examination for the subjects. After that, we input and analyzed the relevant data and results by computer. Results In 1108 cases of hypertension patients, 229 (20.67%) were defined as harmony physique, 879 (79.33%) as biased physique. In patients with biased physique, phlegm-dampness physique accounted for 25.54% (283 cases) , and then came yin deficiency physique and Qi deficiency physique, which accounted for 15.16% (168 cases) and 13.18% (146 cases) , respectively. The biased physique was dominated by single biased physique with a total of 590 cases ( 67.12%) , but the complex physique was also in large quantity, with a total of 289 cases ( 32.88%) . The complex physique consisting of two kinds of single physique was commonly seen in the patients with complex physique, accounting for 15.70%. The complex physique consisting of more kinds of single physique had less percentage. Phlegm-dampness physique was a kind of physique involving the most cardiovascular risk factors. Patients with phlegm-dampness physique had higher incidence of overweight, abnormal lipid level, family history of cardiovascular disease, lack of physical exercise and electrocardiographic abnormality, and the difference was statistically significant compared with other physique types ( P<0.05 or P<0.01) . Conclusion Phlegm-dampness, yin deficiency and Qi deficiency physique are the three commonly-seen constitution types in hypertension patients. Phlegm-dampness physique is the most commonly-seen biased physique and is also a kind of physique involving the most cardiovascular risk factors. Prevention and management in consideration with the constitution characteristics and cardiovascular risk factors will be a new prospective method for the treatment of hypertension patients in community.
