ABSTRACT
Objective:To compare the clinical efficacy of pedicle subtraction osteotomy (PSO) versus vertebroplasty (VP) combined with long segment fixation for nonunion of osteoporotic vertebral fractures with kyphosis.Methods:A retrospective cohort study was conducted to analyze the clinical data of 72 patients with nonunion of osteoporotic vertebral fractures with kyphosis admitted to Jiangnan Hospital affiliated to Zhejiang University of Traditional Chinese Medicine from January 2010 to December 2017. There were 16 males and 56 females, aged 55-84 years [(68.2±5.2)years]. Level of injury was located at T 11 in 3 patients, at T 12 in 19, at L 1 in 31, and at L 2 in 19. According to the American Spinal Injury Association (ASIA) classification, 31 patients were scaled as grade D and 41 grade E. Overall, 51 patients were treated with PSO combined with long segment fixation (PSO group) and 21 patients treated with VP combined with long segment fixation (VP group). The operation time and bleeding volume were compared between the two groups. Before operation, at postoperative 2 weeks and at the last follow-up, the kyphotic Cobb angle, sagittal vertical axis (SVA), thoracic kyphosis (TK) and lumbar kyphosis (LL) were used to evaluate the osteotomy effect, and the visual analogue scale (VAS) and Oswestry disability index (ODI) were used to evaluate the degree of pain and lumbar function recovery. The improvement of ASIA grade was observed at the last follow-up. The complications were observed as well. Results:All patients were followed up for 24-46 months [(33.2±5.9)months].The operation time and bleeding volume were more in PSO group than in VP group (all P<0.01). Before operation, the kyphotic Cobb angle, SVA, TK and LL were not significantly different between the two groups (all P>0.05). At postoperative 2 weeks, TK was not significantly different between the two groups ( P>0.05), while PSO group showed significantly decrease of kyphotic Cobb angle and SVA and increase of LL when compared with VP group ( P<0.05 or 0.01). At the last follow-up, the kyphotic Cobb angle, SVA and TK in PSO group were (8.5±1.1)°, (2.6±0.5)cm and (28.8±6.2)°, respectively, significant lower than those in VP group [(14.2±1.5)°, (4.4±0.9)cm and (32.6±5.9)°] (all P<0.05); while the LL was significantly larger in PSO group [(43.1±3.9)°] than in VP group [(36.9±5.3)°] ( P<0.01). Before operation, the VAS and ODI were not significantly different between the two groups (all P>0.05). At postoperative 2 weeks, the VAS and ODI in the two groups were also not significantly different (all P>0.05), but both were greatly decreased from the preoperative level (all P<0.05). At the last follow-up, the VAS and ODI in PSO group were (1.4±0.5)points and 22.5±2.5, significant higher than (1.8±0.6)points and 25.5±5.1 in VP group (all P<0.01). At the last follow-up, the ASIA classification was grade E in all patients. There were 1 patient suffering from dural matter tear and 1 from proximal junctional kyphosis in PSO group. Whereas 3 patients had bone cement leaking and 1 pedicle screw loosening in PVP group. The complication rate was 3.9% (2/51) in PSO group, significant lower than 19.0%(4/21) in VP group ( P<0.05). Conclusion:Compared with VP group in the treatment of osteoporotic vertebral fractures with kyphosis, PSO combined with long segment fixation is much effective in improving kyphosis angle and spinal axial imbalance correction, maintaining vertebral height and spinal axial stability in middle- to long-term, improving pain and dysfunction and minimizing complications, regardless of more operation time and bleeding volume.
ABSTRACT
Objective:To compare the prognosis of fluoroucil combined with cisplatin and paclitaxel combined with cisplatin regimens with concurrent radiotherapy in treatment of esophageal squamous cell carcinoma.Methods:A total of 120 patients with esophageal squamous cell carcinoma who were admitted to Anyang Tumor Hospital of Henan Province from December 2012 to November 2018 were randomly divided into group A and group B by using a random number generator. Group A was given cisplatin combined with 5-fluorouracil, and group B was given cisplatin combined with paclitaxel. Both groups had the same radiotherapy regimen, and both used intensity-modulated radiation therapy (IMRT). Completions of 50 Gy radiotherapy and at least one cycle of chemotherapy were considered to be in line with the plan. Survival data was analyzed in the term of intention-to-treat (ITT) and per-protocol (PP) set.Results:Of the 120 patients, 114 patients were treated and the adverse reactions could be evaluated, including 55 cases in group A and 59 cases in group B. The incidence of grade Ⅲ-Ⅳ leukopenia in group B was higher than that in group A [49.2% (29/59) vs. 25.5% (14/55)], and the difference was statistically significant ( χ2 = 6.805, P = 0.012), and there were no statistical differences in the other adverse reactions between the two groups (All P > 0.05). A total of 113 cases can be analyzed for survival. According to ITT analysis, the median progression-free survival (PFS) time in group A and group B was 28.0 months (95% CI 15.5-34.5 months) and 27.0 months (95% CI 17.0-41.0 months), the median overall survival (OS) time was 28.0 months (95% CI 15.8-34.2 months) and not reached, the differences were not statistically significant (both P > 0.05). According to PP analysis, the median PFS time in group A and group B was 28.0 months (95% CI 15.8-34.2 months) and 29.0 months (95% CI 14.9-45.1 months), the median OS time in group A and group B was 28.0 months (95% CI 3.7-52.3 months) and not reached, the differences were not statistically significant (both P > 0.05). Conclusions:The fluorouracil combined with cisplatin regimen and paclitaxel combined with cisplatin regimen with concurrent radiotherapy have similar PFS and OS time in treatment of esophageal squamous cell carcinoma, the adverse reactions are different, but they are all tolerable. In individualized clinical practice, the toxicities and costs of the two regimens can be comprehensively considered.

ABSTRACT
Objective: To compare the post-infectious irritable bowel syndrome [PI-IBS] and none post-infectious irritable bowel syndrome [NPI-IBS] clinically and experimentally
Methods: From May 2013 to January 2015, eighty-nine patients with irritable bowel syndrome [IBS]were recruited in the internal department of the affiliated hospital of Shandong University of Traditional Chinese Medicine. The clinical data were collected for all the patients, and a blood sample was collected to detect the level of C-reactive protein [CRP] and intestinal fatty acid binding protein [IFABP], an investigation questionnaire of gastrointestinal symptom rating scale [GSRS] and self-rating anxiety scale [SAS] were carried out to evaluate the gastrointestinal function and anxiety status
Results: In the study, forty-eight patients were included in PI-IBS group and 41 in Non-PI-IBS group. There was no significant difference in age, gender and GSRS between the two groups [p>0.05]. In PI-IBS group 70.8% patients presented with the primary symptom of diarrhea and 60.4% presented with a SAS scores over 50, but in Non-PI-IBS group, the values were only 19% [p<0.05] and 34.1% [p<0.05]. The level of IFABP and CRP were significantly higher in PI-IBS group than those in Non-PI-IBS group [p<0.05]
Conclusion: The PI-IBS may be different from Non-PI-IBS in mechanism and should be treated using different strategies

Objective To evaluate the left ventricular (LV) systolic dyssynchrony after the acute myocardial infarction (AMI) with two-dimensional speckle tracking echocardiography (STE). Methods STE were performed in 65 patients within 72 h of AMI and compared with 60 age- and sex-matched healthy volunteers. The peak longitudinal strain (LS_(peak)) was measured at LV myocardium. LV dyssynchrony was defined as an interval ≥130 ms for the absolute difference in time to peak radial strain for the anteroseptal wall versus the posterior wall (TAS-POST). Size of myocardial infarction (MIS)was confirmed by wall-motion score index (WMSI). Results The LS_(peak) and LV ejection fraction (LVEF) were lower, and WMSI and TAS-POST were larger in AMI patients compared with controls. Forty-two patients had developed LV dyssynchrony (64.62%), and there were strong correlation between LV dyssynchrony (TAS-POST) and LS_(peak), LVEF, and WMSI (MIS). MIS was the most independent predictor for systolic dyssynchrony. Conclusion AMI with normal QRS can induce LV dyssynchrony, which is mainly determined by MIS. STE is a reliable technique for accurate evaluation of LV synchrony.
ABSTRACT
Objective To assess the predictive value of coronary angiography TIMI myocardial perfusion grade (TMPG), electrocardiogram (ECG) single-lend ST segment resolution (STR), ECG Max-ST-segment deviation (MaxSTE) on judging myocardial reperfusion after primary angioplasty in the patients with acute myocardial infarction (AMI). Methods Primary percutaneous coronary intervention(PCI) was performed in 42 patients within 12 hours after AMI onset. Coronary angiography and ECG was done before and after angioplasty. TMPG, ECG single-leed STR and MaxSTE were used to assess myocardial reperfusion immediately after PCI. Myocardial perfusion scan was examined in all the patients using99mTc-MIBI SPECT on day 7±2. Results Compared with the level of myocardial perfusion demonstrated in myocardial scan of 99mTc-MIBI SPECT, the sensitivity, specificity and accuracy of TMPG, single-lead STR and MaxSTE was calculated. The sensitivity of TMPG, single-lead STR and MaxSTE was 93.75%, 87.50% and 81.25%, respectively, the specificity of them was 20.00%, 80.00% and 80.00%, respectively, and the accuracy was 76.19%, 85.71% and 80.95%, respectively. The findings in single-lead STR and MaxSTE matched well with the results of myocardial scan of 99mTc-MIBI SPECT. Conclusion In the patients suffering from AMI treated with PCI, ECG is an effective method to assess myocardial tissue reperfusion.
ABSTRACT
Objective:To test the periodontal regeneration potential after tooth root replantation combined with in vitro cultured periodontal ligament cells (PDLCs).Methods:The third and fourth mandibular premolars of two mongrel dogs were extracted and the dog PDLCs were in vitro cultured.The autologous roots combined with PDLCs were replanted into the created cavities in the right mandibular edentulous area one month after premolar extraction.Roots replanted without PDLCs on the left mandible served as the controls. The dogs were sacrificed 2 months after the replantation. Paraffin sections were made and stained with hematoxylin & eosin, then examined histologically.Results:In the samples of root combined with PDLCs implantation, some fiber bundles vertical to the surface of bone were embedded in some inner walls of the alveolar socket opposite to the apical root.Conclusion:Cultured PDLCs in vitro retain the capacity of PDL-like tissue formation even in the artificial alveolar socket.
