BACKGROUND:Bone cement solidification can improve the stability, strength and mechanical support of fractured vertebrae. However, there are few studies on the effect of bone cement dispersion within the fracture line on percutaneous vertebroplasty. OBJECTIVE:To analyze the effect of bone cement dispersion within the fracture line of thoracolumbar osteoporotic vertebral compression fractures on percutaneous vertebroplasty. METHODS:Totaly 90 patients with thoracolumbar osteoporotic vertebral compression fractures were enroled, 53-80 years old, including 42 males and 48 females. Al these patients underwent percutaneous vertebroplasty with bone cement injection, and divided into two groups according to bone cement dispersion conditions: study group with good bone cement dispersion (n=60) and control group with poor bone cement dispersion (n=30). Visual analogue scale scores, Oswestry dysfunction index, Cobb's angle and adverse reactions were recordedbefore and after treatment. RESULTS AND CONCLUSION:There were no differences in the visual analogue scale score and Oswestry dysfunction index between the two groups before treatment (P > 0.05). The visual analogue scale scores were significantly lower in the study group than the control group at 3 days after treatment and at the last folow-up (P < 0.05); the Oswestry dysfunction index and Cobb's angle were also lower in the study group than the control group at 3 days after treatment (P < 0.05). However, no difference was found in the Oswestry dysfunction index, Cobb's angle and bone cement leakage between the two groups at the last folow-up. These findings indicate that the percutaneous vertebroplasty show better effects on pain relief in patients with good bone cement dispersion that those with poor bone cement dispersion, and the vertebral stability is better as wel as the short-term effect is more obvious.

Objective To compare the safety , surgery effects , pain scores of the close-distance-two-port video-assisted lobectomy and systematic dissection of the mediastinal nodes , and single-port video-assisted thora-coscopic surgery (VATS). Methods Between October 2012 and January 2015 in Peking University First Hospi-tal and Beijing Hospital , 269 patients who were going to be performed lobectomy and systematic lymph node dissection, were gathered and 205 patients were included in this study finally. Of the total, 122 patients were performed close-distance-two-port VATS , and 83 patients underwent single-port VATS. The clinical data were gathered, and statistically analyzed. Result In both groups, no severe postoperative complications or death oc-curred. No significant differences existed between the two groups in terms of intraoperative blood loss , duration and volume of chest tube drainage , postoperative pain score , hospital stay after surgery and hospitalization ex-penses (P > 0.05) but the data about operating time, number of dissected lymph nodes, complications(subcuta-neous emphysema , air-leak from the port of drainage tube and poor wound healing ) were significantly different (P < 0.05). Conclusions Compared with the single-port VATS, the method of close-distance-two-port video-as-sistant lobectomy and systematic dissection of the mediastinal nodes is safe and practicable with definite thera-peutic effect, less operation difficulty and complications.

BACKGROUND:Studies have shown that bisphosphonates inhibit osteoclast resorption, but whether cathepsin K, a key cytokine of bone resorption, plays an effect has rarely been reported.
OBJECTIVE:To study the effect of bisphosphonate on capthesin K and bone resorption function during osteoclast differentiation.
METHODS:Osteoclasts were cultured by mouse monocyte-macrophage cellline-RAW264.7. The cells were divided into two groups:control group, treated with 100μg/L receptor activator of nuclear factorκB ligand factor;alendronate group, treated with 100μg/L receptor activator of nuclear factorκB ligand factor+10-7 mol/L alendronate. Osteoclastogenesis and resorption function of osteoclasts were examined at 7 days of culture and gene expression of capthesin K was detected by immunofluorescence method at 72 hours of culture. Western blot assay was used to detect capthesin K protein expression at 72 hours of culture.
RESULTS AND CONCLUSION:Tartrate-resistant acid phosphatase positive multinuclear cells were observed and resorption lacunae formed in two groups. Control group showed the higher number of tartrate-resistant acid phosphatase positive multinuclear cells and larger size of resorption lacunae than the alendronate group (P<0.01). Immunofluorescence showed expression of capthesin K was higher in the control group than the alendronate group (P<0.01);furthermore, the protein expression of capthesin K was also lower in the alendronate group than the control group (P<0.01). These findings indicate that bisphosphonates could strongly inhibit osteoclastogenesis and its resorption function by inhibiting gene expression of capthesin K.

Objective:To observe the effectiveness of bone cement-enhanced proximal femoral nail antirotation (PFNA) in the treatment of severe osteoporotic intertrochanteric fracture.Methods:Between January 2016 and June 2017, 23 patients with severe osteoporotic intertrochanteric fracture were treated with bone cement-enhanced PFNA at Department of Orthopaedics, The Second Affiliated Hospital to Luohe Medical College. They were 9 men and 14 women with an average age of 85.3 years (range, from 80 to 91 years). According to AO/OTA-2018 classification, there were 2 cases of type 31-A1.3, 5 cases of type 31-A2.2, 13 cases of type 31-A2.3 and 3 cases of type 31-A3.3. According to Singh standard grading, 4 cases were rated as level 1, 16 cases as level 2 and 3 cases as level 3. The PFNA fixation was enhanced by bone cement in all. The operation time, amount of intraoperative bleeding, postoperative complications, fracture healing time and hip Harris scores at the last follow-up were recorded.Results:The operation time averaged 56.3 minutes (range, from 47 to 91 minutes) and the amount of intraoperative bleeding 197 mL (range, from 110 to 450 mL). All patients were followed up for 5 to 27 months (mean, 14.7 months). One patient who had been rated as good by the Harris hip score died 5 months after surgery because of acute suppurative obstructive cholangitis. All the 23 fractures achieved bony union. The healing time averaged 11.3 weeks (range, from 8 to 18 weeks). By the Harris scores at the last follow-up, 11 cases were excellent, 10 cases good and 2 cases fair, giving an excellent and good rate of 91.3%.Conclusion:Bone cement-enhanced PFNA can bring about good short-term outcomes for severe osteoporotic intertrochanteric fractures because it can improve the screw control and reduce the risk of internal fixation failure.
