BACKGROUND:Vertebroplasty and kyphoplasty have been widely applied in the treatment of osteoporotic thoracolumbar compression fracture. However, cement leakage is a major problem in the application of this technology, especial y for the vertebral posterior wal ruptured patients. OBJECTIVE:To investigate the therapeutic efficacy of high viscosity bone cement and vertebroplasty in the treatment of osteoporotic thoracolumbar compression fracture. METHODS:A retrospective study was conducted in 20 cases receiving high viscosity bone cement and vertebroplasty surgery for osteoporotic thoracolumbar compression fracture. Clinical outcomes were evaluated mainly with use of Visual Analog Scale for lower back pain. Function of lower back pain was assessed using Oswestry Disability Index questionnaire. Quality of life was evaluated using 36-Item Short Form Health Survey and Frankel score was applied to evaluate neurological function. The anterior vertebral height of the fractured vertebrae was assessed with X-ray. The bone cement leakage, pulmonary embolism, incidence of nearby vertebral fractures and other complications were evaluated during fol ow-up. RESULTS AND CONCLUSION:Al patients were fol owed up for 12-18 months. The anterior vertebral height of the fractured vertebrae, the lower back pain and function, and quality of life were improved significantly after treatment (P<0.05). Al patients got the same neurological symptoms before surgery. The bone cement dispersion was good after treatment, detected by X-ray and CT scan, only two cases appeared with bone cement leakage, but no clinical symptoms were found. There was no cement toxicity or al ergic complications, pulmonary embolism, infection, nerve injury or new fractures. The high viscosity bone cement used in the treatment of osteoporotic thoracolumbar vertebral compression fractures can significantly relieve thoracic back pain, improve lower back function and quality of life, and greatly reduce the risk of bone cement leakage.

BACKGROUND: Percutaneous vertebroplasty has been gradual y used to treat Kümmel disease because of less trauma and quick pain relief, but there is stil a high rate of bone cement leakage. OBJECTIVE: To investigate the clinical efficacy of percutaneous vertebroplasty with high-viscosity bone cement plus hyperextension position reset for treatment of Kümmel ’s disease. METHODS: The clinical data of 17 patients with Kümmel ’s disease were retrospectively analyzed, including 5 males and 12 females, aged 55-83 years, and al underwent percutaneous vertebroplasty with high-viscosity bone cement plus hyperextension position reset. The visual analog scale, Oswestry disability index score, vertebral body height and vertebral kyphosis angle were determined. The bone cement leakage, pulmonary embolism, adjacent vertebral fractures and other complications were recorded. RESULTS AND CONCLUSION: At the 12th Oswestry disability index scores and vertebral kyphosis angle of patients were significantly lower than those before treatment (P < 0.05), the vertebral body height was significantly higher than that before month of follow-up, the visual analog scale scores, treatment (P < 0.05). After treatment, there were three cases of bone cement leakage, which had no special discomfort and neurological symptoms, and one case of new fractures. These results demonstrate that hyperextension position reset combined with percutaneous vertebroplasty with high-viscosity bone cement in treatment of Kümmel ’s disease can effectively relieve back pain, improve function of the lower back, partial y restore vertebral height and reduce kyphosis angle.

Objective To explore the early clinical effects of lumbar discectomy associated with annulus repair in the treatment of lumbar disc herniation.Methods A prospective study was conducted to review 56 patients with lumbar disc herniation who accepted discectomy surgery in Subei People's Hospital of Jiangsu Province from January 2014 to September 2015,including 28 cases of discectomy associated with annulus repair (repair group) and 28 cases of discectomy (control group).Oswestry disability index and visual analog scale scores were recorded.Simultaneously,incision length,operative time,blood loss,hospitalization time,surgical complications,and postoperative recurrence of lumbar disc herniation were recorded.Results All patients completed the follow-up for 12 to 18 months (14.5 ± 1.3).There was no difference between the repair and control groups in the incision length,blood loss and hospitalization time (P ＞ 0.05).The operative time of the repair group was longer than that of the control group,but the difference was not statistically significant (P ＞ 0.05).The Oswestry disability index and visual analog scale scores for lumbar and lower limb pain significantly decreased in both groups after surgery (P ＜ 0.05).The visual analog scale scores at 24 hours and 3 days after surgery in the repair group were less than that in the control group (P ＜ 0.05).The satisfactory rate of treatment in the repair group was slightly higher than that in the control group,but the difference was not statistically significant (P ＞ 0.05).There was no recurrence in the repair group,but 2 recurrence cases in the control group (P ＞ 0.05).Conclusions These findings indicate that discectomy associated with annulus repair is a safe and reliable method to obtain remarkable early clinical results and can reduce the recurrent rate in the treatment of lumbar disc herniation.

Objective:To explore the trajectory of frailty changes in patients receiving maintenance hemodialysis and analyze its influencing factors.Methods:Maintenance hemodialysis patients at the Blood Purification Center of the Minda Hospital of Hubei Minzu University from January to October 2022 were selected by convenience sampling. The Clinical Frailty Scale (CFS) was used to survey patients at the start of dialysis and one, three, six, and 12 months of dialysis. Latent class growth modeling was employed to identify the potential classes of frailty trajectory changes and analyze the influencing factors of these classes.Results:A total of 255 questionnaires were distributed, with 212 valid responses, yielding an effective response rate of 83.14%. The changes in frailty among the patients receiving maintenance hemodialysis were categorized into three groups: moderate frailty worsening group ( n=64), frailty improvement group ( n=110), and stable pre-frailty group ( n=38). The average probabilities of patients belonging to each latent class were 0.948, 0.938, and 0.950, respectively. Age, gender, body mass index, anemia, continuing to work after illness onset, and comorbidities were identified as influencing factors of frailty trajectory changes in these patients (all P<0.05) . Conclusions:There are three types of frailty trajectory changes in patients receiving maintenance hemodialysis from the start of dialysis to 12 months of regular dialysis. Targeted interventions can be implemented based on the identified influencing factors.

Objective    To evaluate the strategy of chemoradiotherapy following endoscopic R0 resection for esophageal cancer in M3-T1b stage. Methods    There were 45 esophageal cancer patients with M3-T1b stage with endoscopic R0 resection followed by additional chemoradiotherapy from ECETC (Esophageal Cancer Endoscopic Therapy Consortium) as a trial group with 34 males and 11 females at age of 61.37±7.14 years. There were 90 patients with esophagectomy from Fudan University Shanghai Cancer Center as a control group with 63 males and 27 females at age of 61.04±8.17 years. Propensity score match (1:2) was used to balance the factors: gender, age, position, depth of invasion and lymphovascular invasion (LVI), which may influence the outcomes. Overall survival (OS) rate, relapse free survival (RFS) rate, and local recurrence rate were compared between the two groups. Result    There was no statistical difference (HR=2.66 with 95%CI 0.87 to 8.11, P=0.179) in terms of OS rate between the two groups. One, two and three years overall survival rate of patients in the control group was 93%, 86%, and 84%, respectively. Nobody died in the trial group within 3 years after surgery. The RFS rate between the two groups didn’t significantly differ (HR=1.48, 95% CI 0.66 to 3.33, P=0.389). One, two and three years RFS rate of patients in the contorl group was 87%, 78%, and 76%, respectively, while 97%, 93%, and 73% in the trial group, respectively. The local recurrence rates between the two groups didn’t significantly differ either ( HR=0.53，95%CI 0.13 to 2.18, P=0.314). One, two and three years local recurrence rate of patients in the control group was 5%, 6% and 6%, respectively, while 0%, 0% and 21% in the trial group, respectively. Conclusion    Similar outcomes are found regarding OS, RFS and local recurrence rates between the two groups. The strategy of endoscopic R0 resection followed by additional chemoradiotherapy has prospect for the treatment of esophageal cancer in M3-T1b stage. And this kind of therapy may be provided for those with risk factors or can not tolerate surgery.
