All patients of two groups were assessed by JOA scale at 2nd week and 6th month after operation.Results The JOA scores of two groups at 6th month were all higher than that at 2nd week and scores of the rehabilitation exercises group were also higher than that of the normal care group ( P<0.01).Conclusion Rehabilitation exercises after artificial intervertebral disc replacement can improve spine cord function of CSM patient.

A method was developed for analyzing the stable carbon isotope ratio of five volatile components ( Ethanol, Glycerol, Acetic acid, Ethyl lactate, 2-methyl-butanol ) in wine using gas chromatography-combustion-isotope ratio mass spectrometer ( GC-C-IRMS ) . The sample injection volume was less than 0. 5 μL, and the analytical time of each run was less than 14 min. The precision of this method was 0. 08‰-0. 25‰ for analyzing standards, while 0. 09‰-0. 36‰ for wine samples. Compared to element analysis-isotope ratio mass spectrometry ( EA-IRMS) results, the deviations were lower than 0. 5‰. Fifty-four wine samples from France, Australia, America and China were considered. The δ13 C of five volatile components were measured using GC-C-IRMS. Discriminant analysis ( DA) was employed for analyzing the geographical origin traceability of selected wine. The result indicated that δ13 C of volatile components could be used to distinguish the origin of wines. The method was shown to be effective in improving detection of the origin traceability of wine.

【Objective】 To explore the clinical effect of unilateral double-channel endoscope-assisted bone graft fusion and internal fixation (ULIF) in the treatment of recurrent lumbar disc herniation. 【Methods】 The clinical data of 22 patients with recurrent lumbar disc herniation treated by ULIF in our hospital from August 2020 to October 2020 were analyzed retrospectively. The study indicators included intraoperative blood loss, operation time, bed rest time, and hospital stay. The follow-up data included visual analogue score (VAS) of low back pain, Japanese Orthopaedic Association score (JOA), OSwestry disability index (ODI) score, as well as 36 concise health status survey (SF-36) scores before operation, and 1 week and 6 months after operation. 【Results】 The average operation time was (179.15±42.06) minutes, the average intraoperative blood loss was (132.67±41.92) mL, the average bed rest time was (1.51±0.42) days, and the average hospital stay was (4.82±1.13) days. The VAS score of low back pain at 1 week after operation was lower than that before operation (all P<0.000 1), and further decreased during the follow-up. The ODI score, JOA score and SF-36 score of postoperative follow-up were significantly different from those before operation (P<0.05). The satisfaction rate was 86.4% at 1 week after operation and 95.4% at 6 months after operation. The proportion of significant clinical efficacy at 1 week after operation and postoperative 6 months was 18.2% and 63.6%, respectively. 【Conclusion】 ULIF has the advantages of short-term recovery, less intraoperative blood loss, short bed rest and hospital stay, and good medium-term clinical effect. It is a safe and reliable minimally invasive technique for spinal surgeons in the treatment of recurrent lumbar disc herniation.

OBJECTIVE: To investigate the relationship between the changes of serum neutrophil extracellular traps (NETs), soluble vascular cell adhesion molecule-1(sVCAM-1) and deep venous thromboembolism after knee arthroplasty. METHODS: From May 2017 to April 2020, 30 patients with deep venous thromboembolism after knee arthroplasty were retrospectively selected as the observation group, and 60 patients without deep venous thromboembolism after knee arthroplasty in the same period were randomly selected as the control group. The clinical data, serum levels of nets and sVCAM-1 before and 1, 3 and 5 days after operation were compared between the two groups. Logistic regression model was used to analyze the influencing factors of deep venous thromboembolism after knee arthroplasty; Pearson correlation was used to analyze the relationship between serum nets and sVCAM-1 levels;Draw the receiver operating characteristic curve(ROC) to obtain the area under the curve(AUC), and analyze the diagnostic value of serum nets and sVCAM-1 levels for deep vein thromboembolism after knee arthroplasty. RESULTS: There were statistically significant differences between two groups in age, body mass index, and postoperative knee elevation and flexion ratio(P<0.05). The level of serum NETs and sVCAM-1 on the 1st and 3rd day after surgery of the observation group were higher than the control group(P<0.05). Logistic regression analysis showed that age, body mass index, knee flexion position, serum nets and sVCAM-1 levels at 1 and 3 days after operation were all the influencing factors of DVT after knee arthroplasty (P<0.05);Pearson correlation analysis showed that there was a positive correlation between the levels of serum NETs and sVCAM-1 in patients with deep venous thromboembolism after knee arthroplasty 1 and 3 days after operation(P<0.05). The ROC curve of predicting deep venous thromboembolism after knee arthroplasty by serum nets and sVCAM-1 levels at 1 and 3 days after operation was drawn, the results showed that the AUC of serum nets and sVCAM-1 levels at 1 day after operation was higher than that at 3 days after operation, which had a good predictive effect. CONCLUSION The influencing factors of deep vein thromboembolism after knee arthroplasty are age, body mass index, postoperative knee elevation and flexion, postoperative serum NETs and sVCAM-1 levels, especially postoperative serum NETs and sVCAM-1 levels. Changes can be used as potential biomarkers for predicting postoperative deep vein thromboembolism, and clinical attention should be paid to it.

Background: Diminutive (≤5 mm) and small (6-9 mm) polyps are the most common colorectal polyps seen clinically, and a tiny percentage of them contain advanced histology. Aims: To clarify the endoscopic characteristics of diminutive and small colorectal polyps with advanced histology. Methods: A retrospective analysis was conducted in patients undergoing colonoscopic polypectomy in Ningbo First Hospital from June 2016 to September 2021, and the clinical, endoscopic and pathological data were collected. Propensity score matching (1: 1) was performed to select the non - advanced histology controls comparable with diminutive and small polyps with advanced histology. The endoscopic characteristics related to advanced histology was identified by univariate and multivariate analyses. Results: A total of 3 631 diminutive and small adenomatous polyps were detected in 2 950 patients, among them, 14 (1.2%) diminutive polyps and 114 (4.6%) small polyps were diagnosed as advanced histology pathologically, with 14 high - grade intraepithelial neoplasia (HGIN) in diminutive polyps, and 109 HGIN and 5 submucosal invasive carcinoma in small polyps. For serrated lesions, 755 polyps less than 10 mm in diameter were detected in 504 patients, but no advanced histology was diagnosed. Multivariate Logistic regression analysis showed that chicken skin mucosa (OR=3.790, 95% CI: 1.767-8.128), congestion (OR=2.802, 95% CI: 1.450 - 5.415), hemorrhage (OR=5.074, 95% CI: 1.511 - 17.035), lobular changes (OR=2.522, 95% CI: 1.247 - 5.098) and relative depression (OR=5.317, 95% CI: 1.376-20.550) were independent risk factors for advanced histology in diminutive and small polyps, while no correlations were found between JNET classification type 2B and type 3, Paris endoscopic classification type 0 - I and advanced histology. Conclusions: When endoscopic characteristics including chicken skin mucosa, congestion, hemorrhage, lobular changes and relative depression are found in diminutive and small colorectal polyps, advanced histology should be suspected.

Methods Retrospective analysis of 117 patients (137 feet) with congenital clubfoot treated with serial casting in Ponseti approach from March 2008 to June 2014. A repeatable tendo-achilles tenotomy was performed on 102 pa-tients (116 feet) (84.67%) when less than 15o of ankle dorsiflexion and 70oof foot abduction. The foot-abduction brace was used postoperatively and follow-up termly. Results All of 117 patients were follow-up for 3 to 48 months, averag-ing 26.3 months. The results of 112 (131 feet) (91.97%) were satisfactory. The tendo-achilles tenotomy was performed averaged 1.4 times in the patients taken surgery. The tendon performed tenotomy were all connected and patients walk with normal gait later. Conclusion The results of the treatment of repeatable tendo-achilles tenotomy for congenital clubfoot ware satisfactory. This surgery performed in Ponseti approach will always achieve a successful result.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.
