OBJECTIVE: To evaluate the clinical outcomes of single-balloon kyphoplasty in the treatment of thoracic osteoporotic compression fractures via extrapedicular approach METHODS: From July 2004 to May 2008, 38 cases (52 vertebra) of thoracic osteoporotic fractures were treated by balloon kyphoplasty via unilateral extrapedicular approach, including 12 males and 26 females with an average age of 60.3 years (range 55-72 years). There were 34 cases of primary osteoporosis, and 4 had administrated hormone due to other diseases for over 6 months. Symptomatic levels ranged from T_4 to T_(12) confirmed by physical examination, MRI and X-ray. The pain relief, restoration of vertebral height and kyphosis correction were compared before and after operation by using visual analogue scale (VAS) and radiograph, respectively. In addition, bone cement leakage location and complications were recorded. RESULTS: Operation were successfully performed in 38 cases with an average injection of bone cement volume of (3.2+ 1.4) mL (2.25-4.60 mL in unilateral infusion). The mean time of surgery was 25-55 minutes, and that of follow-up was 9.5 months (6-24 months). Back pain of 36 cases was improved, and the VAS 3 days postoperatively and the final follow-up was significantly reduced (P < 0.05). The vertebral anterior margin and median height following surgery were significantly improved detected by X-ray (P < 0.05), and average median height restoration was (50.90+34.60)%, but no significant change was found in posterior height (P > 0.05). No lateral wedging or changes in the coronal alignment was found. Three cases (5 vertebra) had cement leakage: the bone cement of 1 case leaked to posterior margin through the puncture channel, and 2 cases leaked to lateral vertebra through vertebral venous system without any adverse event. The patients could move the second day after surgery, discharged from the hospital at days 3-4, and restored to normal life at 1 month postoperatively. No blood vessel or spinal cord puncture injury or pulmonary embolism, or blood vessel embolism was found. CONCLUSION: Unilateral extrapedicular kyphoplasty is safe and effective in treating thoracic osteoporotic fractures. It rapidly releases backache, restores the body height of fractured thoracic vertebrae and improves quality of life of the patients.

Objective To discuss the clinical efficacy of surgical treatment of pathologic vertebral surgery for thoracic and lumbar tuberculosis. Methods All of 322 cases of thoracic and lumbar spinal tuberculosis patients from December 2003 to June 2014 were retrospectively analyzed in our department. All patients were underwent debridement, fusion and nerve decompres?sion surgery. According to different fixed methods, patients were divided into pathologic vertebral surgery group (fixation complet?ed within lesions invaded motion unit) including 91 males and 100 females, with an average age of 41.53 years, and non?pathologic vertebral surgery group (long segments or short segment fixation) including 61 males and 70 females, with an average age of 42.72 years. We observed the tuberculosis cure rate, degrees of deformity, pain and neurological recovery, operative time, blood loss and complications by follow?up. Results The average follow?up time was 75.52 months in pathologic vertebral surgery group and 76.21 months in non?pathologic vertebral surgery group. The total number of pathologic vertebras in pathologic vertebral surgery group and non?pathologic vertebral surgery group were 277 and 218 respectively, and the average was 1.45 and 1.66. The total number of fixed segments was 277 in pathologic vertebral surgery group and 485 in non?pathologic vertebral surgery group, and the average fixed segments was 1.45 and 3.70. The cure rate was 85.86%in pathologic vertebral surgery group and 85.49%in non?pathologic vertebral surgery group at 6 months postoperatively, and 98.95%and 98.47%at the last follow?up time, with no signifi?cant difference between groups. Graft fusion rate was 89.00%in pathologic vertebral surgery group and 89.31%in non?pathologic vertebral surgery group 6 months postoperatively, 98.38%and 98.47%at the last follow?up time, without significant difference. In lumbar spine, the average correction of Cobb's angle was 12.4° in pathologic vertebral surgery group and 13.1° in non?pathologic vertebral surgery group, and the average angle loss was 1.3 and 1.4°, with no significant difference. In thoracolumbar, the average correction of Cobb’s angle was 10.9°in pathologic vertebral surgery group and 11.1°in non?pathologic vertebral surgery group, and the average angle loss was 1.7°and 1.5° respectively, without significant difference. However, in thoracic, the average correction of Cobb's angle was 10.2° in pathologic vertebral surgery group and 12.7° in non?pathologic vertebral surgery group, and the average angle loss was 3.6° and 2.5°respectively, with significant difference. The mean operation time was 210.45 min in pathologic verte?bral surgery group and 210.45 min in non?pathologic vertebral surgery group, with significant difference. The average blood loss was 726.12 ml in pathologic vertebral surgery group and 726.12 ml in non?pathologic vertebral surgery group, with significant dif?ference. The complication rate was 11.51%in pathologic vertebral surgery group and 11.45%in non?pathologic vertebral surgery group, with no significant difference. Conclusion Pathologic vertebral surgery surgery is a safe, effective and feasible method of operation for treatment of thoracic and lumbar tuberculosis, which can effectively preserve adjacent normal vertebral motion unit features. The thoracic surgery was less satisfactory than the lumbar and thoracolumbar surgery.

Objective:To investigate the mid-term efficacy of Dynesys internal fixation and posterior lumbar interbody fusion (PLIF) in the treatment of grade I degenerative lumbar spondylolisthesis.Methods:From June 2014 to June 2016, 68 cases, in which 35 males and 33 females aged from 44-74 (55.3±7.5), of grade I degenerative lumbar spondylolisthesis treated using Dynesys internal fixation were retrospectively analyzed. There were 8 cases of L 3, 52 cases of L 4 and 8 cases of L 5 with an average visual analogue scale (VAS) of 4.5±2.1. At the same time, 72 patients were treated with posterior lumbar interbody fusion (PLIF). There were 37 males and 35 females aged from 46-76 (56.8±7.2), with 9 cases of L 3, 53 cases of L 4 and 10 cases of L 5. The VAS of this group was 4.4±2.3. The operative time, intraoperative blood loss, postoperative drainage volume and complications were compared between the two groups. Range of motion (ROM), disc height of stable segment and upper adjacent segment, adjacent segment degeneration between the two groups were evaluated. ASD, Oswestry disability index (ODI) score and Japanese Orthopaedic Association (JOA) score were also compared between the two groups. Results:The patients in both groups were followed up. The follow-up time of Dynesys group was 50-74 months, average 64.2±18.3 months, and the follow-up time of PLIF group was 55-79 months, average 65.2±15.5 months. The operation time [(120.5±21.0) min vs. (132.5±27.0) min, t=2.924, P=0.004], intraoperative bleeding [(312.5±80.7) ml vs. (352.5±84.5) ml, t=2.861, P=0.005] and postoperative drainage [(120.3±45.8) ml vs. (140.2±50.2) ml; t=2.446, P=0.016] in Dynesys group were significantly better than those in PLIF group. The differences were statistically significant. There was no significant difference in postoperative ROM of stable segment, ROM of upper segment, disc height of stable segment and adjacent segment between the two groups before operation. At 5 years postoperatively, there was statistically significant difference between the stable segment ROM (4.3°±1.6° vs. 0; t=22.809; P<0.001) and the upper segment ROM (10.5°±2.1° vs. 12.8°±2.2°; t=6.329, P<0.001). At 5 years postoperatively, ODI scores of the two groups were (11.25%±8.12%, 16.53%±9.23%), and JOA scores were (22.60±2.20, 19.01±2.34), which were significantly improved compared with those before surgery, with statistically significant differences (ODI: t=3.585, P<0.001; JOA: t=9.340, P<0.001). There was no significant difference in the incidence of symptomatic ASD between the two groups (8.8% vs. 16.7%, χ2=1.284, P=0.257) , but there was significant difference in the incidence of X-ray ASD between the two groups (2.9% vs. 13.9%, χ2=4.043, P=0.044) . Conclusion:Compared with PLIF, Dynesys internal fixation for degenerative lumbar spondylolisthesis is a minimally invasive, safe and effective surgical method to retard ASD; Compared with PLIF, adjacent segment degeneration can be reduced using Dynesys internal fixation.

Patient satisfaction is one of the core indicators to measure the service quality of medical institutions. To this end, a multi-campus public hospital in Shanghai constructed a management system of patient satisfaction evaluation. Since 2021, its call center has conducted a full coverage satisfaction assessment for discharged patients from its three campuses and collected dissatisfaction information feedback. The hospital organized relevant clinical departments and functional departments to fully communicate with the dissatisfied patients according to the feedback information, followed by a joint rectification. The hospital regularly conducts in-depth analysis of all complaints for timely discovery of common problems in different campuses for continuous improvement. This practice can provide reference for multi-campus hospitals to promote homogeneous management, to improve management efficiency, service quality and patient satisfaction.

OBJECTIVE： To systematically evaluate the efficacy and safety of Tapentadol immediate-release preparation （Tap IR） for relieving severe acute pain after brachiocephalic arteritis， and to provide evidence-based reference for rational drug use. METHODS： Retrieved from PubMed， Medline， Cochrane library， CNKI， VIP， Wanfang database and American clinical trial database， randomized controlled trials （RCTs） about Tap IR （trial group） versus Oxycodone immediate-release preparation or placebo for relieving severe acute pain after brachiocephalic arteritis were collected. After literature screening， data extraction and literature quality evaluation with modified Jadad scale， Meta-analysis was conducted by using RevMan 5.3 software. RESULTS： A total of 6 RCTs were included， involving 2 378 patients. Results of Meta-analysis showed that 48 h total pain relief value （TOTPAR48） of trial group was significantly higher than control group [MD＝35.60，95％CI（27.31， 43.88）， P＜0.000 01]. Results of sub-group analysis showed that TOTPAR48 of trial group using Tap IR 50 mg [MD＝28.68， 95％CI （18.18， 39.17），P＜0.00 001]， 75 mg [MD＝39.97， 95％CI （34.21， 45.73）， P＜0.000 01] and 100 mg[MD＝38.50， 95％CI（1.46， 75.54），P＝0.04] were significantly higher than control group； TOTPAR48 of patients who received Tap IR 75 mg were significantly higher than patients who received Tap IR 50 mg [MD＝9.04，95％ CI（4.31， 13.77），P＝0.000 2]. There was no statistical significance in the utilization rate of rescue medicine （URM） between 2 groups [RR＝1.23，95％ CI（0.84， 1.80），P＝0.29]. Subgroup analysis showed that URM in patients who received Tap IR 75 mg was significantly lower than those receiving Tap IR 50 mg [RR＝0.62，95％CI（0.41， 0.94），P＝0.02]. The total difference of 48 h pain intensity （SPID48） in trial group was significantly lower than control group [MD＝－18.96，95％CI（－37.28，－0.64），P＝0.04]. Subgroup analysis showed that SPID48 in patients who received Tap IR 75 mg was significantly higher than those receiving Tap IR 50 mg [MD＝21.66，95％CI（8.93， 34.39），P＝0.000 9]. There was no statistical significance in the total change of pain impression （PGIC） between 2 groups [RR＝0.95，95％CI（0.88， 1.03），P＝0.23]. Subgroup analysis showed that PGIC in patients who received Tap IR 75 mg was significantly higher than those receiving Tap IR 50 mg [RR＝1.07，95％CI（1.01， 1.13），P＝0.02] but significantly lower than those receiving Tap IR 100 mg [RR＝0.86，95％CI（0.77， 0.97），P＝0.01]. The incidence of nausea， vomiting， constipation， dizziness and headache in trial group were significantly lower than control group （P＜0.05）. CONCLUSIONS： Tap IR shows good therapeutic efficacy and safety for severe acute pain after brachiocephalic arteritis， and the efficacy of Tap IR might be better when the dose of Tap IR is 75 mg.

OBJECTIVE To establish a method for simultan eous determination of 5 kinds of pentacyclic triterpenoids as 3-O- acetyl-pomolic acid in Chaenomeles speciosa ，and to analyze the difference in the contents of C. speciosa from different producing areas by different processing technologies .
