Effect of Modified Shiquan Dabutang on Inflammatory and Bone Metabolism Indexes in Elderly Patients with Osteoporotic Intertrochanteric Fractures Due to Qi and Blood Deficiency / 中国实验方剂学杂志

Objective:To explore the application value of modified Shiquan Dabutang in the treatment of elderly patients with osteoporotic intertrochanteric fractures （OIFs） due to Qi and blood deficiency by observing its impacts on inflammatory and bone metabolism indexes. Method:Ninety-eight elderly patients admitted to our hospital for OIFs of Qi and blood deficiency syndrome from April 2018 to April 2020 were randomized into an observation group （<italic>n</italic>=49） and a control group （<italic>n</italic>=49）. Following the proximal femoral nail antirotation （PFNA） fixation， patients in the control group were treated with Guipiwan， while those in the observation group received the modified Shiquan Dabutang. The clinical efficacy， inflammatory and bone metabolism indexes， and complications were compared between the two groups after four weeks of treatment. Result:The levels of such serum indexes as fibroblast growth factor-2 （FGF-2）， osteoprotegerin （OPG）， transforming growth factor-<italic>β</italic>₁ （TGF-<italic>β</italic>₁）， <italic>β</italic>-endorphin （<italic>β</italic>-EP）， bone-specific alkaline phosphatase （BALP）， and osteocalcin （BGP） in the observation group after treatment were significantly elevated as compared with those in the control group （<italic>P</italic><0.05）， whereas the serum tumor necrosis factor-<italic>α</italic> （TNF-<italic>α</italic>） and <italic>D</italic>-dimer （<italic>D</italic>-D） declined （<italic>P</italic><0.05）. The TCM symptom score in the observation group after treatment was obviously lower than that in the control group， while the Harris Hip Score （HHS） was higher （<italic>P</italic><0.05）. The overall response rate of the observation group was 93.88% （46/49）， higher than 75.51% （37/49） of the control group （<italic>χ²</italic>=6.376， <italic>P</italic><0.05）. The total incidence of incision infection， deep vein thrombosis of lower limbs， and pulmonary infection in the control group was 24.49% （12/49）， significantly higher than 6.12% （3/49） in the observation group （<italic>χ²</italic>=6.607， <italic>P</italic><0.05）. Conclusion:The modified Shiquan Dabutang is able to alleviate inflammation， regulate bone metabolism， promote bone repair， and reduce the incidence of complications in elderly patients with OIFs due to Qi and blood deficiency.

Anatomic and radiological study on posterior pedicle screw fixation in the atlantoaxial vertebrae of children / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To investigate the feasibility of posterior fixation with 3.5-mm pedicle screws in the atlantoaxial vertebrae of children.</p><p><b>METHODS</b>In this study, atlantoaxial vertebrae specimens were obtained from 10 cadavers of children aged 6-8 years. We measured the height and width of the C(1) pedicle and the midportion of C(1) lateral mass; the width of C(1) posterior arch under the vertebral artery groove and the height of the external and internal one-third of this part; the external, internal height and the superior, middle, inferior width of the C(2) pedicle (transverse foramen). Furthermore, computed tomography (CT) axial scan was performed on 20 age-matched volunteers to obtain relative data of their atlantoaxial vertebrae. We measured the length and width of the C(1) and C(2) pedicles in the atlantoaxial cross-sectional plane. On CT workstation, we also measured the angles between the longitudinal axes of the atlantoaxial pedicles and the midsagittal plane.</p><p><b>RESULTS</b>For the cadaveric specimen group, the height and width of the C1 pedicle were (5.26+/-0.44) mm and (6.26+/-0.75) mm respectively. The height of the medial one-third of the C1 posterior arch under the vertebral artery groove was (4.07+/-0.24) mm. The external, internal height and superior, middle, inferior width of the C2 pedicle was (6.86+/-0.48) mm, (6.67+/-0.49) mm, (6.63+/-0.61) mm, (5.41+/-0.39) mm and (3.71+/-0.30) mm, respectively. For the volunteer group measured by CT scan, the height and width of the C(1) pedicle were (5.47+/-0.34) mm and (6.63+/-0.54) mm respectively, while (6.59+/-0.51) mm and (5.13+/-0.42) mm of the C2 pedicle. The angles between the atlas, axis pedicles and the midsagittal plane were (9.60+/-1.32) degree and (27.80+/-2.22) degree respectively.</p><p><b>CONCLUSION</b>It is feasible to place a 3.5-mm pedicle screw in the C(1) and C(2) pedicles of children aged 6-8 years old.</p>
